Endoscopic removal is contraindicated due to the high danger of package deal perforation, with resultant drug overdose. Operative intervention is indicated when bowel obstruction, failure to progress, or drug leakage/toxicity is suspected. In a large research, as a lot as 45% may require surgery with gastrotomy, enterotomy, or colotomy carried out based upon the placement of the packages. A latex hood or overtube can be particularly helpful in removing long, sharp, pointed objects to defend the rectal mucosa from laceration and to overcome the tendency of the anal sphincter to contract on attempted removing of objects. Although aware sedation will typically facilitate removal, general anesthesia can allow most dilation of the anal sphincter to help take away bigger and more advanced objects. Factors that improve the chance for complications embody removing of sharp and pointed objects, an uncooperative patient, a quantity of and/or deliberate ingestion, and extended length of time from meals impaction or overseas body ingestion. More generally, colorectal foreign our bodies had been inserted into the rectum intentionally or unintentionally. Radiographs should be obtained previous to making an attempt removing of colorectal international bodies for higher visualization of the location, orientation, and configuration of the object. To avoid health care supplier harm, attempts at handbook removing or digital rectal examination ought to be deferred until the presence of a pointy or pointed object has been excluded. Manual digital extraction could additionally be profitable for the removing of small, blunt, palpable objects within the distal rectum. Conscious sedation could additionally be enough for handbook removing in some patients, but examination and extraction beneath basic anesthesia may be required in others to permit greater anal sphincter rest and profitable object extraction. The three most common types of bezoars encountered are phytobezoars, composed of vegetable matter; trichobezoars, made up of hair or hair-like fibers; and medication bezoars (pharmacobezoars). Offending vegetables and fruits embrace celery, pumpkin, prunes, raisins, leeks, beets, and persimmon. Trichobezoars happen most commonly in younger ladies and youngsters from ingestion of enormous quantities of hair, carpet fiber, or clothes fiber. Trichobezoars are more often associated with psychiatric problems, psychological retardation, or pica. The clear majority of sufferers with bezoars (other than trichobezoars) have a predisposing factor that decreases emptying of gastric contents. Prior gastric surgery is evident in as many as 70% to 94% of patients with bezoars. Patients with diabetes or end-stage renal illness and patients on mechanical ventilation are at larger threat for bezoar formation. A history of earlier bezoar, gastric surgical procedure, or gastric dysmotility ought to be considered. Physical examination often assists little in the analysis, though occasionally a palpable stomach mass may be appreciated. Halitosis as a outcome of the putrefying supplies of the bezoar residing in the abdomen may be present. On distinction radiography, a gastric bezoar classically presents as filling defects inside the stomach. Medication bezoars will be seen as entire tablets or pill fragments in the midst of the material. Treatment Smaller bezoars could additionally be handled with conservative medical management; often this consists of a liquid diet for a brief period of time and a prokinetic agent to promote gastric emptying. Fragmentation could be carried out with the endoscope itself, with accessory gadgets like forceps or snares, or with instillation of saline or water flushes Clinical Features Patients with gastric bezoars could additionally be asymptomatic, however most (80%) have obscure signs of epigastric discomfort. Rapunzel syndrome is a term used to describe trichobezoars located primarily within the abdomen that reach previous the pylorus and into the duodenum, causing bowel obstruction and even jaundice or pancreatitis because of obstruction on the level of the ampulla of Vater. The fragments of the bezoar could be pushed into the small bowel or removed by mouth. If many of the bezoar is to be eliminated, an overtube is really helpful to facilitate frequent passes of the endoscope and to shield the airway. Mechanical disruption and endoscopic removing will be profitable in 85% to 90% of gastric bezoars. Laparoscopic removing can first be tried in bezoar removing however conversion to an open surgical procedure may happen in simply over half of sufferers.

There can also be diarrhea (a results of fast gastric emptying) and dumping syndrome. Respiratory symptoms, including respiratory distress at start and stridor, as nicely as recurrent pulmonary infections, have been reported. Anemia due to iron deficiency may happen as a outcome of decreased gastric acid secretion could preclude enough iron absorption; cobalamin (vitamin B12) deficiency could observe hyposecretion of intrinsic issue. The decrease esophageal sphincter is poorly defined, and esophagogastric reflux is often extreme. Because of the danger of malignancy related to distal gastric diverticula, surgical therapy by amputation, invagination, or segmental resection has been really helpful. Location is contiguous with the stomach, typically alongside the higher curvature or posterior wall, and accommodates all layers of the gastric wall. The duplication hardly ever communicates with the abdomen so for that reason, a tubular, fusiform, or spherical cystic mass develops. Infrequently, there could additionally be a connection to the colon, pancreas, or pancreatic duplication; the connection could also be the result of an acquired fistula from a penetrating peptic ulcer within the gastric duplication. Several embryologic defects have been proposed as etiologies for duplications, including errors in separation of notochord and endoderm, persistence of embryonic diverticula, and persistence of vacuoles inside the epithelium of the primitive foregut. Aside from concurrent duplications, vertebral anomalies are the second most commonly linked abnormality. Treatment the medical administration of microgastria contains frequent small-volume feedings or continuous-drip feedings into the stomach. An different is nocturnal drip feedings by way of jejunostomy to supplement oral intake. Surgical creation of a double-lumen Roux-en-Y pouch anastomosed to the greater curvature of the stomach has been described. This Hunt-Lawrence jejunal pouch has allowed normal development and improvement and prevented reflux and dumping syndrome. The true congenital diverticulum accommodates all gastric tissue layers and is positioned on the posterior wall of the cardia. The intramural (or partial) diverticulum initiatives into however not via the muscular layer, most commonly situated alongside the larger curvature of the antrum. The false (or pseudo-) diverticulum is fashioned by mucosal and submucosal herniation via a defect in the muscular wall and lacks muscularis propria. Clinical Features and Diagnosis the scientific presentation of gastric duplication is dependent upon factors similar to measurement, location, and speaking structure (if any). Diagnosis is suggested by an abdominal radiograph displaying displacement and extrinsic compression of gastric lumen. Contrast radiography might reveal the duplication by way of a mass impact on the abdomen. Contrast radiography shows a rounded, well-delineated mobile pouch, typically with an air-fluid level. On endoscopy, the diverticulum is seen as a well-delineated opening; distention by the scope could reproduce signs. Symptoms may be epigastric or lower chest ache, indigestion, bleeding, or nonbilious emesis. The differential prognosis consists of an acquired gastric diverticulum present in affiliation with pancreatitis, gastric outlet obstruction, trauma, ulcer disease, or malignancy. Hiatal hernia and hypertrophic gastric folds might mimic a diverticulum on contrast research. Additionally, mucosectomy or mucosal surface ablation ought to be thought-about as a end result of the event of malignancy in enteric duplications has been documented in adults. D, An intraoperative picture of the gastric duplication after dissection of the stomach and before resection. Gastric Teratoma Gastric teratomas are benign neoplasms of the abdomen that occur virtually solely in males. These tumors could have their origins in pluripotential cells and include all 3 embryonic germ cell layers. Most are located alongside the greater curvature of the stomach and are extragastric, though intramural extension has been reported. Premalignant modifications and frank malignant transformation to adenocarcinoma have been reported,30,31 and peritoneal gliomatosis has been observed.

A 25-yr-old lady with hypertension used self-induced vomiting to improve her blood strain by eliminating the effect of her antihypertensive medication. Her motive was to obtain a prolonged hospitalization so as to keep away from a tense home setting. The explanation for dying at autopsy was attributed to problems from pulmonary microcrystalline cellulose emboli, which doubtless resulted from self-injection of oral treatment by way of a central line. A psychiatrist examined the affected person and famous main melancholy with melancholia, recurrent type, with somatization, and an amphetamine was prescribed. The medicine seemed to help initially, and the affected person was feeling higher the subsequent day; nevertheless, on the following day, he was once more having severe stomach ache after meals. Progress notes acknowledged, "Pattern of complaints and his response to antidepressant are indicative of psychogenic ache problem coupled with dependent/oppositional personality dysfunction," and "Patient continues to be fairly regressed. He does appear depressed, however the ache syndrome appears psychogenic in origin (not a depressive equivalent) and secondary to his dependent narcissistic character construction. After taking a psychiatric historical past and observing the patient, the psychiatrist made a prognosis of "psychogenic ache," a time period that implies that ache is brought on primarily and maintained by emotional misery. This analysis was totally accepted by the gastroenterologist, and the affected person was transferred to a psychiatric unit of the hospital. Moreover, there were no clues suggesting constructive evidence for irregular sickness habits. Second, the psychiatrist ought to have recognized that secondary acquire is a half of normal sickness habits, and he should have acknowledged that there was no supporting proof for abnormal illness behavior.

Prior to that, we current a quick general discussion of the cellular mechanisms of radiation damage and introduce the concept of an organ that features in series versus one that capabilities in parallel, which informs radiation dose constraints. Conversely, the rate of radiation-induced apoptosis in endothelial cells is significantly decreased in animals missing the proapoptotic bcl-2 multidomain proteins, bax and bak. Beyond the acute loss of cells by way of apoptosis and mitotic catastrophe, radiation injury is the consequence of a complex set of interactions between cells involving multiple cytokines and molecular pathways that can acutely lead to mucosal edema, and chronically to fibrosis and organ dysfunction through excess deposition of extracellular matrix coincident with a discount within the expression of remodeling enzymes such as matrix metalloproteinases. Severe acute reactions can result in treatment breaks and, in turn, a suboptimal treatment course, whereas the concern for chronic toxicity, particularly to the small bowel, is usually a dose-limiting consideration in the creation of a remedy plan. Submucosal reaction exhibits large, bizarre radiation fibroblasts which have each cytomegaly and nucleomegaly. Mitigating the risk and severity of radiation enteritis and chronic small bowel damage is commonly the dose-limiting factor in the radiotherapeutic administration of most stomach and pelvic malignancies. Whether this manifests clinically is partly related to the practical association of the organ, of which there are 2 varieties: serial and parallel. Organs arranged in collection are composed of segments which may be reliant on the performance of the preceding phase such that the lack of any individual phase will make the organ dysfunctional or even nonfunctional downstream, and possibly upstream, from the insult. The prototypical organ with this arrangement is the spinal cord, the place vital injury at a single spinal degree can cause loss-of-function at each level downstream of the damage. Organs with parallel architecture, on the opposite hand, have some practical redundancy built in such that the lack of segments up to a degree might not manifest clinically. The liver has this type of arrangement, although debate continues on exactly how a lot liver need be preserved to remain totally practical particularly in patients with underlying liver disease. Organs with a parallel practical architecture are topic to constraints that enable for the safety of an sufficient relative quantity of practical tissue. As might be discussed within the case of the liver, it could be very important not permit an absolute volume to obtain greater than a sure dose of radiation. Irradiation of intestinal mucosa primarily affects the clonogenic intestinal stem cells throughout the crypts of Lieberk�hn (cells that provide, through self-replication and eventual maturation, replacement cells within the intestinal villi). Stem cell harm, as a outcome of direct radiation damage or radiationinduced microvascular damage, results in a lower in mobile reserves for the intestinal villi. This results in mucosal denudement, shortened villi, a decreased absorptive floor space, and associated intestinal inflammation and edema.

In addition to its functional absence, no immunologically reactive lipase could be detected,418 suggesting both the whole absence of pancreatic lipase or the incidence of a major structural change affecting both immunogenicity and function. The response to exogenous pancreatic enzyme remedy is suboptimal, and limitation of dietary fats is often necessary to avoid oily stools and incontinence. Colipase deficiency has been described in male offspring of consanguineous and non-consanguineous marriages. Colipase activity is markedly reduced, with in any other case normal pancreatic enzyme secretion. Fat absorption improves dramatically with the intraduodenal instillation of purified colipase. Apparently, diabetes was not a characteristic of the syndrome as a result of each patients did properly on pancreatic enzyme replacement alone. Although few stories of congenital absence of enterokinase (enteropeptidase) have appeared because the unique description in 1969,427 a familial nature was instructed by its documentation in siblings.

The calcium launch into the cytosol causes a rapid rise in the focus of free calcium that mediates the secretory response. The continued stimulation of enzyme secretion by these brokers additionally depends on the inflow of extracellular. Pancreatic acinar cell agonists that stimulate digestive enzyme secretion act via 2 separate pathways. That is, the noticed response is bigger than could be anticipated from the additive responses of the individual agonists acting alone. The underlying mechanism entails the cholinergic nervous system in addition to the hormones motilin and pancreatic polypeptide. Digestive Secretion Like gastric secretion, exocrine pancreatic secretion with ingestion of a meal is split into 3 phases: cephalic, gastric, and intestinal. The extent of cephalic stimulation of exocrine pancreatic secretion in people has been evaluated via measurement of exocrine secretions stimulated by sham feeding (chewing and spitting out the food). One study80 indicated that sham feeding stimulated pancreatic enzyme secretion at up to 50% of the maximal secretory fee, with no increase in bicarbonate secretion when acidic gastric secretions have been prevented from coming into the duodenum. When gastric secretions had been allowed entry into the duodenum, the speed of pancreatic enzyme secretion rose to about 90% of maximal, and bicarbonate was also secreted. These outcomes counsel that cephalic stimulation particularly increases acinar secretion within the pancreas, and that a low pH in the duodenum (from gastric acid) augments acinar secretion as well as causes ductal bicarbonate secretion. Acetylcholine is definitely a major neurotransmitter concerned in mediating cephalic part pancreatic secretion as a end result of cholinergic antagonists tremendously reduce and in some circumstances abolish sham feeding�stimulated pancreatic secretion in humans. The main stimulus is gastric distention, which causes predominantly secretion of enzymes with little secretion of water and bicarbonate. Balloon distention of both the gastric fundus or the antrum ends in a low-volume, enzyme-rich secretion by means of a gastropancreatic vagovagal reflex. Three gastric processes-secretion of acid, pepsin, and lipase; digestion; and emptying-are tightly coupled to the mechanisms of the intestinal phase of pancreatic secretion. The intestinal part begins when chyme first enters the small gut from the stomach. Secretin is launched from enteroendocrine S cells within the duodenal mucosa when the pH of the lumen is less than four. Immunoneutralization of secretin with a selected antisecretin antibody decreases meal-stimulated pancreatic volume and bicarbonate secretion by as a lot as 80%. Thus the complete mealstimulated response outcomes from a mix of mediators. During the intestinal part, pancreatic secretion of digestive enzymes is mediated by intraluminal fatty acids greater than 8 carbons in length, monoglycerides of those fatty acids, peptides, amino acids, and, to a small extent, glucose. The components of the secretory mechanism during the intestinal section of a meal previously described are activated when normal vitamins enter the duodenum. However, the magnitude of stimulation varies as a perform of type of vitamins and site of supply of the nutrients. Such information is important for strategies to provide nutrients to patients with pancreatic disorders corresponding to acute or continual pancreatitis. With acute pancreatitis, stimulation of the pancreas can exacerbate the severity of the illness; in persistent pancreatitis, stimulation of the pancreas can exacerbate pain (see Chapters fifty eight and 59). Gastrointestinal Teaching Project, American Gastroenterological Association; 2003. These releasing elements are probably mediators of the physiologic feedback mechanism for enzyme secretion. Measurements of pancreatic functions have been tailored to use with endoscopic procedures and should embrace measurements of proteins and protein modifications in pancreatic juice. Indirect checks of pancreatic secretory function include measurement of (1) pancreatic enzymes in duodenal samples after nutrient ingestion, (2) products of digestive enzyme action on ingested substrates, and (3) pancreatic enzymes within the stool. Which pancreatic operate take a look at must be used is determined by the scientific question and the traits and availability of the take a look at. The major drawbacks to the direct exams are the necessities for duodenal intubation and the fact that not all centers are proficient in performing the studies properly.

Primary tumors of the peritoneum include mesothelioma and desmoplastic round cell tumors. Adhesions could additionally be congenital, but the overwhelming majority is acquired as a end result of peritoneal damage. Intraperitoneal overseas bodies corresponding to suture materials, clips, and mesh additionally contribute to adhesion formation. Intra-abdominal adhesions could be a appreciable supply of morbidity and mortality. Adhesions are a quantity one explanation for secondary infertility in girls, accounting for 15% to 20% of cases. Adhesions might preclude peritoneal dialysis or intraperitoneal chemotherapy ought to they be essential. Extensive adhesions may preclude laparoscopic procedures and have been shown to increase blood loss, operative time, and danger of enterotomy in reoperative surgical procedure. These sufferers are then at elevated risk for postoperative complications and extended hospital keep. Tissue damage, hemorrhage, and inflammation within the peritoneal cavity lead to fibrin deposition on the peritoneal surfaces, allowing adjoining surfaces to adhere on this sticky matrix. Various strategies for prevention of adhesion formation embrace discount of peritoneal injury, inhibition of the inflammatory response, prevention of fibrin formation, Clinical Features Patients with peritoneal metastases are often identified late as a end result of inadequate imaging. The pathognomonic manifestations of peritoneal metastases are ascites and malignant bowel and ureteral obstructions, which may happen impartial of one another. Some sufferers current with abdominal wall metastases (including umbilical nodules recognized by the eponym "Sister Mary Joseph" nodules) that are easy to detect. In patients with excessive danger of peritoneal metastases, such findings should promptly trigger a laparoscopy to examine the peritoneum. Presence of such symptoms generally portend a worse prognosis and interventions at this stage are usually limited in their therapeutic profit with healing intent. This has led many investigators to try diagnosis of peritoneal metastases with proactive laparoscopies. The incidence of visualizing in any other case undetectable peritoneal metastases in resectable (and borderline resectable) pancreas cancer ranges from 8% to 20%. Thus, the presence of peritoneal fluid in the absence of inflammatory processes is suspicious for metastases. Exudative ascites seems in patients as evidence of a sophisticated manifestation of a identified tumor with a large tumor burden, rather than as a primary manifestation of most cancers. In the absence of peritoneal metastases, huge liver metastases, hepatocellular carcinoma with or with out cirrhosis, malignant lymph node obstruction as in lymphoma, and Budd-Chiari syndrome with or with out inferior vena cava obstruction, are also related to ascites. Ascitic fluid characteristics usually permit their distinction, which is important because every may require totally different therapy (see Chapter 93 for particulars of pathogenesis and ascitic fluid analysis). Cytology can often detect peritoneal metastases (except in sure histologies corresponding to mesothelioma) and the ascites is extra typically serous and mucinous than sanguineous (see Chapter 93). Patients with ureteral obstruction are generally by the way found to have hydronephrosis on imaging. Progression of hydronephrosis can lead to uremia, with nausea and vomiting mimicking bowel obstruction. Prompt relief of the obstruction with ureteral stents or percutaneous nephrostomy tubes can alleviate worsening renal dysfunction. Malignant bowel obstruction is a common terminal occasion for sufferers presenting with peritoneal metastases. Commonly, there are multifocal areas of obstruction, although a dominant obstruction may be advised. Patients typically present with belly pain, cramping from closed loop obstruction, and emesis. The sigmoid colon and proximal jejunum are widespread websites of obstruction from metastatic illness. Malignant Bowel Obstruction the management of malignant bowel obstruction often requires placement of a nasogastric tube. Soft sialistic nasogastric tubes can provide more comfort than standard Salem sump tubes. Supplemental administration options embody using octreotide, proton pump inhibitors (to reduce acid secretion), anticholinergics similar to hyoscamine to reduce spasms, and analgesia.

Finally, you will want to notice that the scientific symptoms associated with late radiation injury are often difficult to distinguish from these brought on by recurrent or new main malignancies. Patients with strictures or ulcerations should also be evaluated to differentiate chronic radiation adjustments from most cancers recurrence. Radiation to the stomach in animals using a really excessive single dose leads to erosive and ulcerative gastritis. A barely decrease single dose ends in gastric dilatation and gastroparesis, with substitute of the normal gastric mucosa by hyperkeratinized squamous epithelium. With even lower doses, gastric obstruction occurring months after irradiation was noticed, with an atrophic gastric mucosa and intestinal metaplasia seen in surviving animals. Even with a comparatively low dose of 18 Gy delivered in 10 fractions, approximately 40% of ulcer patients had a 50% discount in gastric acid secretion that lasted for a yr or more. Histologic adjustments include disappearance of cytoplasmic details and granules in parietal and chief cells as early as 1 week into remedy. Cell injury and subsequent cell demise are often seen first in the depths of glands, adopted by thinning of the gastric mucosa. Additional mucosal adjustments embrace deepening of the glandular pits and proliferation of cells in the glandular neck. Loss of glandular architecture and thickening of the mucosa could be seen by the third week of radiotherapy. Signs of recovery of early radiation injury to the stomach embody re-epithelialization and fibrosis. Symptoms of acute radiation injury of the stomach consist primarily of nausea and vomiting, dyspepsia, anorexia, belly ache, and malaise. Radiation-induced nausea and vomiting could happen throughout the first 24 hours following treatment. It is estimated that approximately half of patients receiving upper belly radiation will experience emesis within 2 to three weeks following radiation initiation. Symptomatic gastritis occurred roughly 2 months following radiation completion, with ulcer formation occurring at a median of 5 months. Six of 233 patients (3%) required surgery for ulcer hemorrhage or ache associated to ulcer illness, virtually all of whom had obtained doses of larger than 50 Gy. Patients who obtained doses greater than 50 Gy experienced gastric ulceration and gastric ulcer�associated perforation at rates of 15% and 10%, respectively. Of the 7 patients enrolled, 3 experienced gastric or duodenal ulcers with extreme bleeding, requiring transfusion. Patients receiving dexamethasone showed a pattern toward improved full management of nausea (50% vs. The authors concluded that the addition of dexamethasone resulted in modest improvement in safety against radiation-induced emesis. Careful dietary support along with antiemetic therapy is important for patients present process radiotherapy to the stomach. With more extreme issues of bleeding, ulceration, gastric outlet obstruction, fistula formation, or perforation, sufferers could require endoscopic therapeutic approaches or rarely surgical intervention with partial gastrectomy. Top panels, Endoscopic view of the rectum reveals the attribute nice tortuosity and curling of the brand new vessels. Nevertheless, the mechanisms underlying acute and persistent accidents of the large intestine are similar to these of the small intestine. There is a decrease within the stem cell mitotic fee, resulting in a depletion of precursor cells required to replenish the epithelium because it normally sheds. Acute harm could be accompanied by superficial mucosal erosions and lamina propria hemorrhage. Late radiation giant bowel adjustments can lead to fluid and electrolyte malabsorption, obstruction, chronic proctitis, and fistula formation. Symptoms often begin 2 to three weeks into treatment and usually resolve inside several weeks to 3 months following radiation completion. A relationship between the incidence of acute and persistent radiation damage is unsure. Patients could present with tenesmus, bleeding, low-volume diarrhea, rectal ache, and occasionally low-grade obstruction or fistulae (see Table forty one. The rectum can be a readily accessible organ by endoscopy, permitting early diagnosis and intervention, probably stopping symptomatic development.

Other vascular lesions that occur within the small intestine include the blue rubber bleb, hemangioma, angioma, Dieulafoy lesion and portal hypertensive enteropathy (discussed later). B, the bleeding level was a small defect without endoscopic evidence of ulceration. The normal mean reduction in variety of transfusions after 1 12 months of remedy was 0. Two studies analyzed using thalidomide for refractory bleeding, and both showed a lower in rebleeding charges and transfusion necessities. The abnormality is the presence of an artery of persistently large caliber in the submucosa and, in some cases the mucosa, typically with a small, overlying mucosal defect. Dieulafoy known as the lesion "exulceratio simplex" as a result of he thought it was the initial stage of a gastric ulcer. It is believed that focal pressure from these giant "caliberpersistent" vessels thins the overlying mucosa, resulting in erosion of the uncovered vascular wall with resultant hemorrhage. If discovered, tattooing of the lesion is advocated by some authorities to allow for speedy identification of the lesion ought to rebleeding happen. Mesenteric angiography is used when endoscopy fails to localize a site of hemorrhage and could additionally be of specific profit in patients with lesions in the colon or rectum the place the view could be obscured by lively bleeding and poor bowel preparation. Endoscopic treatments are thought-about protected and efficient at attaining hemostasis with success rates reaching 75% to one hundred pc. Combination endoscopic remedy with injection adopted by thermal or mechanical therapy is superior to monotherapy and has achieved hemostasis in 95% of circumstances. Hemangiomas are structurally sophisticated lesions characterised by an excess of blood vessels, often veins and capillaries, in a focal space of submucosal connective tissue. Hematochezia is much less frequent, besides with giant cavernous hemangiomas of the rectum, which can trigger huge hemorrhage. The prognosis is greatest established by endoscopy, together with enteroscopy because radiologic studies, even including angiography, regularly are normal. The analysis of cavernous hemangioma of the rectum usually may be suggested on plain films of the stomach by the presence of phleboliths and displacement or distortion of the rectal air column. On barium enema, the affected rectal lumen sometimes exhibits narrowing and rigidity, scalloping of the rectal wall, and widening of the presacral area Endoscopically, one sees elevated plum-red nodules or vascular congestion; ulcers and proctitis also may be present. Grossly, cavernous hemangiomas seem as polypoid or mound-like reddish purple mucosal lesions. Histologically, quite a few dilated, irregular blood-filled spaces are seen inside the mucosa and submucosa and generally lengthen through the muscular wall to the serosal floor. The vascular channels are lined by flat endothelial cells with flat or plump nuclei relying on their age. Younger hemangiomas have plump endothelial nuclei and infrequently reveal mitotic exercise, a characteristic not present in older lesions; vascular lumina remain small and irregular. During involution, the fibrous septa thicken, the endothelial cells are changed by adipocytes, and the vascular buildings atrophy. The endothelial cells are large, often hypertrophic, and in some areas could type solid cords or nodules with ill-defined capillary spaces. Small hemangiomas which may be solitary or few in number and approachable endoscopically could be ablated. Most massive or multiple lesions require resection of either the hemangioma alone or the concerned section of colon. Local measures to control large bleeding from cavernous hemangioma of the rectum normally are efficient solely temporarily. Embolization and surgical ligation of main feeding vessels also have been used, however in the end, excision of the rectum usually is required. The occurrence of bleeding or anemia in childhood usually results in the analysis, and surgical intervention may be required for steady, gradual bleeding or for intussusception. A, Plain film of the pelvis reveals a gentle tissue mass with foci of calcification in irregular vascular channels. This appearance of pelvic phleboliths in a baby is pathognomonic for a cavernous hemangioma.
