Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract, occurring in 2-3% of the population. Enterolith formation associated with MD is a rare entity. We present the case of a 35-year-old active duty sailor who presented with a 24-hour history of worsening abdominal pain and nausea. His exam revealed lower abdominal peritonitis. An abdominal and pelvic CT scan revealed a fluid-filled structure in the pelvis adjacent to the distal small bowel with associated calcifications. Exploratory laparotomy was performed, which revealed an acutely inflamed MD associated with enterolith formation. Consideration of this condition in the differential upon presentation of an acute abdomen is essential, secondary to the morbidity that can accompany it when misdiagnosed.

Meckel's diverticulum, an omphalomesenteric remnant caused by the failure of the vitelline duct to involute by the seventh or eight week of gestation, was first described in 1809 by Johann Friederick Meckel. It is the most common congenital abnormality of the small intestine. It is usually located in the last 90 cm of the terminal ileum and is formed by all layers of the small intestine. It frequently contains heterotopic tissue, usually gastric mucosa. Here we report a 15-year-old white female who presented to the emergency ward with abdominal pain. Laparatomy was performed with the diagnosis of acute abdomen. A Meckel's diverticulum was found in the mesenteric aspect of the ileum. Histologic examination of the specimen revealed the presence of pancreatic tissue and oxyntic and antral type gastric mucosa showing chronic peptic ulceration apart from intestinal mucosa. This case report underlines the need for a revision in our understanding and classification of Meckel's diverticulum.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract. Inflammation, bleeding and obstruction are its main complications. Formation of enterolith is rare. A case of acute abdomen caused by Meckel's diverticulitis with enterolith is reported.

Meckel's diverticulum (MD) is a congenital disorder that results from an incomplete obliteration of the vitelline duct. MD may give rise to bleeding, intestinal obstruction and inflammation; however its perforation by a foreign body is an extremely rare life-threatening complication. We report on a 52 years-old Brazilian Amazon man presenting symptoms and signs of acute abdomen with an initial suspicion of acute appendicitis. However, the right diagnosis was made only during exploratory laparotomy when the appendix was found to be normal, whereas MD was found to be inflamed and perforated by a chicken bone. The patient was treated successfully with resection of a segment of the ileum, including the perforated diverticulum, and had an uncomplicated postoperative course.

Meckel's diverticulum is the most prevalent abnormality of the gastrointestinal tract seen in approximately 2% of the population. Diagnosing complicated diverticulum is difficult, for its capacity to mime multiple disorders such as appendicitis, ulcer disease, enterocolitis, Chron disease, sigmoid diverticulitis, cholecystitis, and it should be considered in all patients with unexplained chronic abdominal pain, nausea, vomiting, gastrointestinal bleeding, unexpected cause of intestinal obstruction or acute abdomen. Herewith we provide an illustrative presentation, emphasizing the difficulties in preoperative diagnosis of complicated Meckel's diverticulum and underlining the nonspecific nature of the subjective and objective findings. Both cases were admitted to our clinic with acute abdomen diagnoses--first case as a intestinal obstruction and in second case was acute appendicitis. Laparatomy ascertain that the cause of symptoms was the complicated Meckel's diverticulum.

Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. The presence of malignant lesions arising in the diverticulum is very rare, the most common malignant lesion being sarcoma, followed by carcinoid tumors, and less frequently by adenocarcinomas. We present the case of an 86-year-old man who developed acute abdomen. Surgery revealed a perforated Meckel's diverticulum. Histology identified a poorly-differentiated adenocarcinoma arising in Meckel's diverticulum. We provide a review of the literature.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract (approximately 2% of population), and arises from improper closure and absorption of the omphalomesenteric duct. Very few cases of Meckel's diverticulitis on the mesenteric side have been reported in the surgical literature, and no reported cases have been documented on preoperative imaging. We report a 65-year-old woman presenting symptoms and signs of acute abdomen with an initial suspicion of acute appendicitis. MDCT imaging revealed a mesenteric abscess in the right lower quadrant at the level of the distal ileum as a complication of Meckel's diverticulitis on the mesenteric side. The patient recovered after a diverticulectomy without the need for a small bowel resection. This case demonstrates that MDCT is a fast imaging technique that may be helpful in the emergency setting for the preoperative diagnosis of an unusual complicated MD on the mesenteric side.

Incidental carcinoid tumor of the Meckel's diverticulum is an uncommon event. Herein, a case of a carcinoid tumor in Meckel's diverticulum that was incidentally found in a patient with acute appendicitis is presented. A 42-year-old Caucasian man presented with acute abdomen and clinical signs of acute appendicitis. A typical appendectomy was performed during which further abdominal exploration revealed a Meckel's diverticulum 60 cm proximal to the ileocecal valve, with an irregular and somewhat indurated serosal region on one side. A stapled diverticulectomy was performed. Pathology revealed an incidental carcinoid tumor measuring 1 cm within the Meckel's diverticulum. CT scan of the abdomen and 24-h urine 5-hydroxyindoleacetic acid results were normal. The patient had an uneventful recovery and was discharged at the 5th postoperative day. He is alive and without evidence of disease 23 months after the operation. Coexistence of acute appendicitis along with an incidental Meckel's diverticulum raises controversies in their surgical management. We discuss the issues in managing patients with two or more of these coexistent pathologies.

Meckel's diverticulum (MD) occurs in 2-4% of the population and is the most common congenital abnormality of the gastrointestinal tract. A 67 year-old woman was admitted with acute abdomen. Abdominal X-ray showed pneumoperitoneum. During explorative laparoscopy a large perforated MD was found over the right hepatic lobe. CT-scans from an earlier admission revealed the MD but it was misinterpreted on that occasion. An MD in this place and in a person of this age is extremely rare. This case can primarily serve as differential diagnosis when CT-scans reveal mysterious subphrenic configurations.

The aim of the study was to estimate the incidence and analyse the clinical profile and surgical outcome of the Meckel's diverticulum. This prospective study included 632 patients who were operated upon for acute abdomen during August 1999 to July 2004 in a single surgical unit. Pre-operative abdominal ultrasonography and plain x-ray abdomen erect were done depending on the necessity. These patients were subjected to laparotomy/appendicectomy depending on the case. A search for Meckel's diverticulum was done and if found, surgical resection and analysis by histopathological confirmation of the Meckel's diverticulum was performed. This study detected 9 patients (1.42%) with Meckel's diverticulum during the operation. In none of these cases pre-operative diagnosis of Meckel's diverticulitis was made. Out of 9 patients, 6 (66.6%) were males, 3 (33.4%) females. Four cases (44.4%) were symptomatic due to Meckel's diverticulum and 5 (55.6%) were asymptomatic. One patient presented with haematochezia, one with intestinal obstruction due to gangrene of the Meckel's diverticulum and one case of duplication of (double) Meckel's diverticulum. Histopathological examination of these specimens confirmed 2 cases with inflammation, one with gangrene and one ulcerated gastric mucosa in the Meckel's diverticulum. In 2 cases (22.2%) there was heterotopic epithelium (gastric-1, colonic-1). It is recommended that a search for Meckel's diverticulum in every case of appendicectomy, laparotomies for acute abdomen should be conducted and if found, Meckel's diverticulectomy/resection should be performed to avoid secondary complications arising from it.
