Meckel's Diverticulum (MD) is the most common congenital anomaly of gastrointestinal tract, occurring in 2% of the population. It is a true diverticulum and histologically all four intestinal layers are present within MD. There are various complications related to a Meckel's diverticulum, including haemorrhage, intestinal obstruction, inflammation and perforation. Axial torsion followed by gangrene of MD is the rarest of the complications that have been reported. The exact mechanism for torsion is unclear. Preoperative diagnosis of torsion of MD is difficult and often confused with appendicitis as pain is usually localized to right lower quadrant. Radiological investigations do not provide much help in diagnosis. We report a case of axial torsion of MD presenting as acute abdomen in an 11-year-old female patient. The diagnostic laparoscopy was performed. Confirmatory diagnosis and further surgical management was done by exploratory laparotomy under general anaesthesia.

Meckel's diverticulum is a remnant of the proximal part of the vitellointestinal duct and is the most common congenital anomaly of the gastrointestinal tract. It may either remain asymptomatic or present with myriad of clinical presentations. Gastrointestinal bleeding is the most common presentation in children whereas it is intestinal obstruction in the case of adults. We report a 9-year-old boy who presented with acute onset of periumbilical pain and nonbilious vomiting. His clinical and laboratory parameters were unremarkable, except for serum amylase levels. He was conservatively managed initially as acute pancreatitis with paralytic ileus. However, the child deteriorated in a course of 2 days with bilious vomiting, abdominal distension, and dehydration. Imaging was suggestive of an ileoileal intussusception, and exploratory laparotomy identified Meckel's diverticulum as the lead point for the intussusception. The histopathological examination revealed inflamed heterotopic pancreatic tissue at the apex of the diverticulum thus explaining the elevated amylase levels. This case is reported to highlight the atypical presentation of Meckel's diverticulum and the high clinical suspicion warranted in diagnosing such concomitant intussusception.

We would like to present the case of a 76-year-old female patient with cecal necrosis, which is a rare cause of acute abdomen in elderly women and a variant of ischemic colitis. The patient was admitted to our hospital with abdominal pain, anorexia, and nausea. Physical examination, laboratory parameters, and abdominal computed tomography revealed acute abdomen. We operated the patient with an infra-umbilical midline incision. Considering the pain localized to the right lower quadrant, our initial diagnosis was acute appendicitis; however, we kept in mind other differential diagnoses as well. After laparotomy Non-occlusive cecal necrosis was detected. Arterial pulse was palpated; however, no signs of trombus were detected. Patient also have a Meckel's diverticulum. Terminal ileum plus cecum resection and Meckel's diverticulum excision were performed. Isolated necrosis of the cecum may be caused due to multiple reasons. Especially in elderly female patients with predisposing factors like hypotension, sepsis, shock, drug use, vasculitis, and hypercoagulability, cecal necrosis should be kept in mind.

Heterotopic or ectopic tissue is a congenital anomaly, which is defined as the presence of the tissue outside its normal location, without neural, vascular, or anatomic connection with the main body of an organ in which it normally exists. This tissue is usually discovered incidentally and may be asymptomatic or may present with nonspecific gastrointestinal (GI) symptoms. Pancreatic and gastric heterotopia are the two predominantly occurring heterotopic tissues in the GI tract.[12] The prevalence of ectopic pancreatic tissue in the GI tract ranges from 0.6% to 13.7% of autopsy series and it can be present anywhere in the GI tract with the most common localizations being stomach (27.5%), duodenum (25.5%), colon (15.9%), esophagus, and Meckel's diverticulum.[345] It is a rare finding in the gallbladder and its prevalence has not been ascertained due to lack of large-scale studies and systematic review of literature. Similarly, heterotopic gastric tissue is common throughout the GI tract from the tongue to the rectum,[67] but it is extremely rare in the gallbladder with only around 34 cases reported in literature so far, while other cases of different types of heterotopic tissues in the gallbladder such as liver tissue and others such as adrenal and thyroid tissues have been described.[8] The most common presentation of ectopic tissue in the gallbladder is colicky pain in the epigastrium or right upper quadrant sometimes associated with nausea and vomiting. Here, we are presenting two incidentally detected cases, each of gastric and pancreatic heterotopias in the gallbladder.

The prevalence of small intestinal diverticula (SID) in the population is 0.5-2.3%, and in most cases they are asymptomatic. In the presence of small intestinal bacterial overgrowth this results in chronic diarrhea and malabsorption. When it is complicated by diverticulitis it causes pain and other symptoms of inflammatory bowel disease. Inflammatory process progression may be accompanied by bleeding, invagination, intestinal obstruction, diverticulum abscess and perforation with peritonitis development. SID include separate nosological forms such as paraphateral diverticulum and Meckel's diverticulum. In diagnosis of SID ray and endoscopic methods are crucial. The basis of small intestine diverticular disease treatment is intestinal antiseptics, antibiotics as well as surgical intervention for severe complications. Two cases are discussed, the first one confirms a possibility of development of severe malabsorption syndrome with chronic diarrhea, and the second one is a complication in a form of severe diverticulitis, abscess with perforation and peritonitis.

A 38-year-old female presented to the emergency department (ED) with acute-onset right lower quadrant abdominal pain following two days of nausea and vomiting. Physical examination revealed right lower quadrant tenderness to palpation, rebound tenderness, and guarding. Point-of-care ultrasound (POCUS) of the right lower abdomen was performed and interpreted as probable appendicitis. However, upon laparoscopic examination of the abdomen, a benign-appearing appendix was visualized. Further investigation revealed the source of the patient's pain to be a torsed Meckel's diverticulum. Although rare, a torsed and inflamed Meckel's diverticulum can be visualized by POCUS in the ED without the need for further imaging or delay.

Heterotopia is the presence of normal physiologic tissue in an atypical location. Gastric heterotopia has been described in various locations throughout the gastrointestinal tract, including the small intestine. Gastric heterotopia of the small intestine typically is asymptomatic but may present in several ways with symptoms of obstruction, bleeding, perforation, intussusception, or pain. However, gastric heterotopia is rare beyond the duodenum except for its frequent association with Meckel's diverticulum. This entity should be considered in the differential diagnosis of polypoid lesions presenting with symptoms of bleeding or obstruction especially in younger patients. We present a case of gastric heterotopia of the jejunum in a patient with a prior history of Meckel's diverticulectomy after he presented with obstructive symptoms. His symptoms improved following resection of two jejunal polyps via antegrade double-balloon assisted enteroscopy with fluoroscopy. On histopathlogical examination, findings were consistent with gastric heterotopia. This case highlights the importance of considering gastric heterotopia in the differential diagnosis of polypoid lesions located beyond the ligament of Treitz in younger patients presenting with obstructive symptoms.
