1/25. Perforation of acute calculous Meckel's diverticulitis: a rare cause of acute abdomen in elderly.Complications of the Meckel's diverticula are well-known and defined. However, acute inflammation and perforation secondary to a calculus is a rare clinical presentation. A case of acute calculous Meckel's diverticulitis with perforation in a 58-year old man is presented and possible pathological conditions are discussed. Location of the perforation, apical microscopic focal ulcers, and ischaemic changes in the diverticulum remind the pathogenesis comparable to that of acute calculous cholecystitis. This case report with major complications related to Meckel's diverticulum strengthens the concept of prophylactic resection of Meckel's diverticulum in adults, incidentally discovered at laparotomy.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
2/25. 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 = inflammation (Clic here for more details about this article) |
3/25. carcinoid tumor in a Meckel's diverticulum: hypothesis on mutual embryological origin.Congenital defects presenting at an adult age are subject to diagnostic errors because of their relative rarity and often odd clinical presentation. We illustrate a 63-year-old male patient with multiple ileal carcinoid tumors along with a carcinoid tumor in Meckel's diverticulum. The Meckel's diverticulum is a congenital abnormality arising from a patent vitelline duct and is found at the anti-mesenteric side of the ileum. In the Meckel's diverticulum, ectopic tissue or neoplasms are sometimes found, which may lead to intussusception, hemorrhage, or inflammation. The carcinoid tumor is a neuroendocrine neoplasm originating from the neural crest and is diagnosed at virtually all ages. It may exhibit malignant behavior but generally has a mild clinical course. It is most often found in endodermally derived organs, especially the digestive and pulmonary tracts, and coexists frequently with malignant tumors, predominantly of endodermal origin such as colorectal carcinoma. The carcinoid tumor and Meckel's diverticulum are known to coincide, whereas the carcinoid is not really considered to be an embryologically determined defect. We hypothesize that both lesions are derived from local erroneous interaction among the neural crest and the endoderm.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
4/25. Bleeding from a Meckel's diverticulum after the use of ibuprofen.A Meckel's diverticulum is an unusual site of gastrointestinal bleeding in adults. Bleeding often results from ulceration of ileal mucosa that lies adjacent to ectopic gastric mucosa. We report on a 27-yr-old man who bled from a Meckel's diverticulum after receiving oral ibuprofen, a nonsteroidal antiinflammatory drug. Examination of the resected diverticulum revealed fundal-type gastric mucosa with inflammation, submucosal hemorrhages, erosions and ulceration in the absence of helicobacter pylori. The ileal mucosa was spared in this patient. These features suggest that oral ibuprofen caused damage to the ectopic gastric mucosa, precipitating significant hemorrhage. This is the first report in the English literature of such an occurrence.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
5/25. intestinal obstruction caused by omphalomesenteric duct remnant: usefulness of laparoscopy.The anomalies related to omphalomesenteric duct remnant constitute an uncommon cause of intestinal obstruction, of which Meckel"s diverticulum and its variants represent the most important clinical presentation. In most cases they are asymptomatic and usually affect young patients. When symptomatic, they usually present episodes of gastrointestinal bleeding or acute abdomen syndromes caused by strangulation of intestinal loops as a result of fibrous intraabdominal remnants or inflammation produced by the diverticulum. In most cases, the unexpected presence of these alterations makes intraoperative diagnosis necessary. Treatment is surgical and consists in exeresis of the diverticulum or the fibrous band causing the clinical picture. We report two cases of persistence of the vitelline duct resolved by laparoscopic approach.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
6/25. Acute ulcerative colitis in a Meckel's diverticulum.This report describes the case of a patient with acute ulcerative colitis who underwent an emergency colectomy and removal of an incidental Meckel's diverticulum which appeared inflamed. histology showed acute inflammation of colonic epithelium within the Meckel's diverticulum, justifying its removal and confirming that this was indeed a 'skip lesion'.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
7/25. Early appendicitis--a safe diagnosis?INTRODUCTION: Serosal inflammation of the appendix in association with a significant peritoneal exudate can be mistaken for early acute appendicitis. We highlight the importance of looking for other sources of intra-abdominal sepsis in this clinical setting. CLINICAL PICTURE: We present 3 cases of so-called "mild" appendicitis with serosal inflammation that was ultimately shown to be caused by Meckel's diverticulitis. TREATMENT: All 3 patients initially underwent an appendicectomy. In 2 of these cases, a further laparotomy and excision of a Meckel's diverticulum was carried out. All 3 made an uneventful recovery. CONCLUSION: Meckel's diverticulitis can mimic acute appendicitis in clinical history, physical findings and operative findings. It is important to always consider this as a possible cause for an acute abdomen.- - - - - - - - - - ranking = 2keywords = inflammation (Clic here for more details about this article) |
8/25. Spontaneous haemoperitoneum secondary to a Meckel's diverticulum.Meckel's diverticulum is a relatively common gastrointestinal entity which occasionally causes complications. Meckel's diverticulum is classically described to mimic acute appendicitis when inflamed as well as being a cause of unexplained luminal gastrointestinal bleeding. An unusual cause of spontaneous non traumatic haemoperitoneum found during surgery performed for a suspected acute appendicitis in a 22-year old female is described. The patient was found to have a significant haemoperitoneum due to a bleeding serosal vessel of a Meckel's diverticulum. The diverticulum was routinely excised. It was macroscopically and histologically devoid of inflammation. The bleeding vessel was not found to be abnormal or part of an arteriovenous malformation.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
9/25. Migrating calcified enterolith and chronic anemia: an unusual case presentation of a Meckel's diverticulum.Meckel's diverticulum is the most common congenital anomaly of the small intestine, occurring in about 2 % of the population. The most common complications associated with a Meckel's diverticulum include obstruction, bleeding, and inflammation (7, 9, 11, 18-20). The estimated lifetime risk of developing symptoms with a Meckel's diverticulum is 4-6 % (16), with the risks of complications decreasing with age. Stones within Meckel's diverticulum are recognized as a rare complication in the adult population (13,15). However, it has not been reported in the pediatric age group. The authors describe a 19-month-old male who presented with intermittent abdominal pain and vomiting, chronic microcytic anemia and a calcified stone in the lower abdomen, who was found to have a Meckel's enterolith.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
10/25. Meckel's stone ileus.Meckel's diverticulum is the most common congenital abnormality of the small bowel; it occurs in approximately 2% of the population. Complications of Meckel's diverticulum include hemorrhage, usually associated with heterotopic tissue within the diverticulum, intussusception, development of benign or malignant neoplasms, and inflammation. Formation of one or more enteroliths within a diverticulum is rare. An extremely rare complication is mechanical small bowel obstruction secondary to extrusion of an enterolith from a Meckel's diverticulum (Meckel's stone ileus). A case of Meckel's stone ileus is described herein, with a review of the literature of this extremely rare complication.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
