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.

Meckel's diverticulum, which is a remnant of the omphalomesenteric or vitelline duct, is the most common congenital abnormality of the gastrointestinal system. Urachal abnormalities, resulting from anomalous urogenital development, are not observed frequently and case reports are mainly represented in literature. The presence of these two congenital anomalies together is a very rare pathology. Complications arising from a Meckel's diverticulum or urachal remnant may clinically mimic acute appendicitis and other surgical pathologies. We report on a patient who underwent surgery for acute appendicitis when it was discovered that the symptoms were produced by a perforated Meckel's diverticulitis. In the course of the surgery, a urachal remnant was found to coexist with the diverticulum.

Foreign body perforation of Meckel's diverticulum is a very rare event. We report two cases of fish bone perforation of Meckel's diverticulum that presented within 5 days of each other. Both patients presented with acute abdomen and were initially suspected to have acute appendicitis. The diagnosis was only made at surgery when the appendix was found to be normal and Meckel's diverticulum was found to be inflamed and perforated by a fish bone. Both cases were treated successfully with Meckel's diverticulectomy.

Acute appendicitis in infants is a very unusual disease, but associated to structural defects like patent peritoneovaginal duct, Meckel's diverticulum, clubfeet, and Moebius syndrome is extremely rare. Case report. A male of two months-old with this association is presented. Left inguinal swelling and acute abdomen syndrome were identified. In laparotomy, iguinal defect and a gangrenous appendicitis were observed. Appendectomy was performed and postoperative recovery was unevenful.

Abdominal fistula caused by an ingested wooden spit, which penetrated the intestinal wall and remained in the abdominal wall: a laparascopy was performed in a 41-year-old man suffering from acute appendicitis and an inflamed Meckel's diverticulum. After removal of the appendix and the diverticulum, a fistula developed in the excision channel of the left quadrant of the abdominal wall post-operatively. Despite repeated incision of the abscess in the course of 2 months, the fistula did not heal. Ultrasound examination of the abdominal wall was therefore performed. The postoperative status was without conspicuous findings. We could, however, detect a foreign body, a few centimetres long and 2-3 mm thick, displaying a smooth surface, deep down in the abdominal wall. A fistulography confirmed the diagnosis. After removal of the wooden spit, complete healing of the fistula in the abdominal wall was observed. Subsequently, the patient reported to have eaten a beef roulade, fixed with a wooden spit, 7 weeks before the abdominal operation.

At our institution, helical CT of the abdomen and pelvis with intravenous and rectal contrast (CTRC) has become the modality of choice for investigation of patients with right lower quadrant pain and clinical suspicion of acute appendicitis. CTRC has proven useful for the diagnosis of acute appendicitis (AA) and at the same time identifies alternative diagnoses mimicking AA. This pictorial assay illustrates the imaging findings of AA and its mimickers including primary epiploic appendagitis, right-sided diverticulitis, torsion of Meckel's diverticulum, gynecologic disorders, obstructive uropathy, right lower lobe pneumonia, and other conditions.

An unusual case of acute abdomen was caused by the inflammation of ectopic pancreatic tissue in a Meckel's diverticulum. A 49-year-old man presented with acute abdominal pain, and the clinical diagnosis of acute appendicitis was established. During laparotomy, a normal appendix of unusual localization near the gallbladder and a Meckel's diverticulum with an inflamed tip were found. Histological examination showed acute inflammation of heterotopic pancreatic tissue along with normal ectopic gastric and duodenal mucosa within the wall of the diverticulum. Fat necrosis was also ascertained. The authors believe that this is the first report of acute inflammation of ectopic pancreatic tissue and the presence of normal ectopic gastric and duodenal tissue in the same Meckel's diverticulum.

The study was done, to determine the factors for negative appendicectomies. This prospective descriptive study includes patients managed at four non teaching and a teaching hospital of Karachi from March 2006 to February 2008. One hundred and sixty eight patients underwent appendicectomy during the study period. Details of clinical presentations, investigations, operative findings and histopathology were entered and analyzed. Literature search was aimed to see the negative appendicectomy rate (NAR) in last ten years despite using diagnostic tools (clinical scoring, diagnostic imaging and laparoscopy). In this study a total number of 168 patients under went appendicectomy. Normal appendices were found in 31 patients (negative appendicectomy rate was 18.45%) and associated pathology was seen in 13 patients, an incidental finding of Meckel's diverticulum in 5 patients and no other pathology was seen in 13 patients. The different factors which we identified for negative appendicectomies in our practice were non teaching hospitals where diagnostic scoring system was difficult to apply, female gender, selective use of imaging modality, other pathologies presenting with pain in right lower quadrant (RLQ) and requiring surgical intervention, and non-availability of CT scan and laparoscopy. Despite many advances in diagnostic system, acute appendicitis is still a diagnostic dilemma at times. Although there is no substitute for clinical judgment but in sub groups of patients in whom the possibility of negative appendicectomy is high, diagnostic modalities should be used judiciously to decrease the negative exploration.

Over the last 20 years, the treatment of acute appendicitis has been transformed by the development of the laparoscopic approach. And yet the net value of this approach continues to be debated. Laparoscopic appendectomy is associated with a lower complication rate and a shorter period of disability in the general population. While operative costs are higher, the global cost of laparoscopic appendectomy is lower than for open appendectomy. There is a somewhat higher rate of abdominal abscess for the laparoscopic route. Laparoscopic appendectomy shows clear advantages in obese patients and in those with gangrenous or ruptured appendicitis. The laparoscopic approach is contra-indicated during pregnancy due to a higher incidence of miscarriage. Treatment of the appendiceal stump by ligature decreases the expense associated with the use of a surgical stapler. When Meckel's diverticulum is encountered during appendectomy, it should be removed in all pediatric patients; in adults, Meckel's diverticulectomy in adults should be performed only for clear-cut pathology. Surgeons continue to innovate and refine appendectomy techniques but many questions remain to be answered.

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.
