Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula. Exploratory laparotomy revealed a vesico-diverticular fistula resulting from a perforated Meckel′s diverticulum. Pathologic examination revealed that the diverticulum did not contain ectopic gastric or pancreatic tissue. The patient underwent a diverticulectomy and had an uneventful postoperative course. Unlike four of the six previously reported cases, our patient had no coexisting bowel or bladder disease occurring with her vesico-diverticular fistula. Conclusion: This is only the third reported case of a vesico-diverticular fistula resulting from a perforated Meckel′s diverticulum that did not contain ectopic tissue.
Gastro-intestinal stromal tumors (GISTs) of the appendix are a rare entity. To date, only eight cases has been described in the literature, most of which have been of the benign type. We report a new case of an appendiceal GIST in a 75-year-old man. The tumor was discovered when the patient presented with acute appendiceacal peritonitis. Preoperative diagnosis of appendiceal GIST was rarely done as tumors were usually associated with appendicitis-like symptoms.
The independent risk factors for conversion to open surgery included male sex, diabetes mellitus, total bilirubin level, and TG13 grade. TG13 grade was found to be the most powerful predictive factor for conversion as it had the highest OR.
A right hepatic artery arising from the superior mesenteric artery is a frequent anatomic variation. Surgeons must be aware of this to ensure the integrity of the hepatic artery blood supply in patients treated by pancreaticoduodenectomy. Despite controversy about the reality of the mesopancreas (postulated in analogy to the mesorectum), because of the absence of fibrous sheath or fascia, its complete removal in pancreatic head carcinoma is feasible by a subadventitial dissection of the superior mesenteric artery which can be considered as the real limit of the mesopancreas.
Laparoscopic cholecystectomy, for acute cholecystitis, during the first 24 h of onset of symptoms, significantly reduced conversion to open surgery and total hospital stay without increasing postoperative complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
