1/52. Heterotopic pancreas as lead point in intussusception: new variant of vitellointestinal tract malformation.Two cases of intussusception are reported with heterotopic pancreatic tissue attached to and draining into the ileum. The first patient, a boy aged 16 months, presented with ileoileal intussusception. The diagnosis was confirmed on ultrasound scan. laparotomy and resection were performed. A 12-mm nodule of heterotopic pancreatic tissue was identified in the ileal serosa at the apex of the intussusceptum, fully formed with acinar tissue, islets, and draining duct. The second patient, also a boy aged 16 months, presented with obstructed ileocolic intussusception in which the lead point at surgery resembled a Meckel's diverticulum. Histopathology revealed a similar 10-mm nodule of fully formed pancreatic tissue in the ileal serosal tissues, with some acinar tissue extending through the wall of the intestine alongside ductal structures. In both cases there was ectopic gastric mucosa either in the distal part of the draining duct or in the small intestine itself at the opening. Heterotopic pancreas is a rare cause of intussusception. We propose that this lesion is of vitellointestinal tract origin, conceptually similar to a Meckel's diverticulum but without a diverticulum as such. Heterotopic pancreatic tissue occurring alone is more common in the proximal small intestine, duodenum, and stomach than in the ileum, and it is often asymptomatic.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
2/52. An incidental case of human Heterophyes nocens infection diagnosed by sectional morphology in a biopsy specimen of the small intestine.A case of human infection with Heterophyes nocens (heterophyidae) was incidentally found in a biopsy specimen of the Meckel's diverticulum at the upper part of the small intestine. The patient was a 58-year-old man living in a rural area of Talsonggun, Kyongsangbuk-do. He had gastrointestinal symptoms such as epigastric pain, indigestion, and abdominal discomfort for 3 months, and severe diarrhea, abdominal pain, and vomiting for about 1 month before hospitalization. endoscopy of the upper part of the small intestine revealed a Meckel's diverticulum, and it was excised and histopathologically examined. Three adult flukes were incidentally found sectioned in the mucosa, and they were identified as H. nocens. The patient had a history of eating raw mullets at a fish market in Pusan 6 months ago, and the mullets were presumed to be the source of infection. This case brings a considerable interest in that specific diagnosis of heterophyid infections could be done by sectional morphology of the worms.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
3/52. A Meckel's diverticulum containing pancreatic tissue and nesidioblastosis in a patient with beckwith-wiedemann syndrome.A 30-month-old twin with beckwith-wiedemann syndrome underwent exstirpation of a nephroblastoma from the right kidney. A Meckel's diverticulum (MD), an incidental finding intraoperatively, was resected because it was indurated and enlarged. Histologically, the MD contained ectopic gastric and pancreatic mucosa. nesidioblastosis was identified within the pancreatic tissue. This is probably the first description of ectopic nesidioblastosis within a MD.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
4/52. Enterolith causing bleeding in a patient with Meckel's diverticulum. Angiographic demonstration.angiography demonstrated a bleeding Meckel's diverticulum supplied by tortuous, presumably embryonic branches of the superior mesenteric artery. A large enterolith, partially impacted into a constriction near the center of the diverticulum, caused a bleeding ulcer. The diverticulum contained no gastric mucosa.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
5/52. Massive bleeding in an adult patient suffering from Meckel's diverticulum.The case of a 22-year-old male who bled from a Meckel's diverticulum is described. The diagnosis was achieved after 99mTechnetium pertechnetate scintigraphy. With the administration of somatostatin very clear images were obtained. The histological examination confirmed the presence of ectopic gastric mucosa. The literature, over the last 10 years, has been reviewed to identify factors associated with bleeding in adults. Ectopic gastric mucosa is the most important factor predicting bleeding. The diagnostic approach to bleeding Meckel's diverticulum and the improvement in the quality of 99mTechnetium pertechnetate scintigraphy, following administration of somatostatin, is discussed.- - - - - - - - - - ranking = 2keywords = mucosa (Clic here for more details about this article) |
6/52. The value of angiography in diagnosis of Meckel's diverticulum: case report.Meckel's diverticulum is the most common anomaly of the gastrointestinal tract and usually produces no symptoms, although the classic symptom is painless rectal bleeding in a child. Because most symptomatic diverticula in children contain ectopic gastric tissue, radionuclide imaging using a technetium 99m pertechnetate scan is considered to be the method of choice. However, a bleeding Meckel's diverticulum may not be detected by pertechnetate imaging despite the presence of ectopic gastric mucosa. When the scan is negative, visceral angiography is an alternative procedure for detecting Meckel's diverticulum. We encountered a case of pathology-proven Meckel's diverticulum whose angiography result was diagnostic, while upper gastrointestinal panendoscopy, colonofibroscopy, barium enema studies, and repeated radionuclide scans were all negative. We report on this case to emphasize the potential role for angiographic detection of Meckel's diverticulum.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
7/52. Ectopic gastric mucosa presenting as a polypoid mass within a Meckel's diverticulum.A 32-year-old man presented with severe abdominal pain located in the mesogastrium and right hemi-abdomen. A barium transit study showed a tubular structure of 6 cm arising from a bowel loop in the distal ileum, with an intraluminal polypoid mass near the bottom. diagnosis of a benign lesion within a Meckel's diverticulum was made. Anatomopathology confirmed a Meckel's diverticulum and demonstrated that the polypoid mass was caused by an unusual great ectopic island of gastric mucosa.- - - - - - - - - - ranking = 5keywords = mucosa (Clic here for more details about this article) |
8/52. Synchronous gastric adenocarcinomas in a patient with Meckel's diverticulum.Meckel's diverticulum, which is the most common congenital anomaly of the gastrointestinal tract, occurs when the vitelline duct persists past the 7th week of gestation. Although complications may occur in 8% to 22% of patients with Meckel's diverticula, adenocarcinoma is very uncommon. We describe a patient with early gastric cancer who was incidentally found to have a superficial adenocarcinoma arising from ectopic gastric mucosa within a Meckel's diverticulum. To the best of our knowledge, synchronous gastric adenocarcinoma in a patient with Meckel's diverticulum has not been previously reported.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
9/52. A case of carcinoid of Meckel's diverticulum associated with gastric adenocarcinoma.Meckel's diverticulum is an uncommon gastrointestinal congenital anomaly that occurs in 1-3% of the population. It is sometimes associated with complications related to the presence of ectopic tissue (obstruction, ulceration, hemmorhage, inflammation, perforation, fistula and tumors). Neoplastic degeneration of Meckel's diverticulum mucosa is rare, developing in only 1-5% of all diverticula, usually asymptomatic and occasionally discovered. disease is metastatic, usually to the liver, in 25% of cases. We report a case of asymptomatic unsuspected carcinoid of Meckel's diverticulum with ileal, hepatic and mesenteric metastasis discovered during a gastrectomy performed for gastric adenocarcinoma. The patient underwent ileal and meckel diverticulum resection, excision of mesenterial metastasis and liver bisegmentectomy. Furthermore, total gastrectomy with esophago-jejunal anastomosis was performed. After an 18-month follow-up period, the patient is alive and disease free. Owing to possible neoplastic degeneration, Meckel's diverticulum should be resected when occasionally discovered. In the presence of a carcinoid tumor, even if associated with metastatic disease, extended resection is recommended.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
10/52. Cystic Meckel's diverticulum: A rare cause of cystic pelvic mass presenting with urinary symptoms.An atypical form of Meckel's diverticulum is presented. A 5-year-old girl was admitted with recurrent urinary tract infections. ultrasonography showed a cystic mass, which pressed and displaced the urinary bladder on its posterosuperior aspect. laparotomy results showed a cystic mass originating from the antimesenteric border of the ileum, which was attached tightly to the urinary bladder. It was diagnosed as a cystic Meckel's diverticulum, which had undergone abscess formation with preservation of the ileal mucosa in some areas and had severe inflammatory changes on its wall. The case is unique both in the mode of presentation and type of complication.
