Meckel’s diverticulum is a common asymptomatic congenital gastrointestinal anomaly. However, its presentation as an inverted Meckel's diverticulum is a rare complication, of which few cases have been reported in the literature.

Here, we report the case of a 33-year-old man with iron deficiency anemia without manifestation of gastrointestinal bleeding. An upper gastrointestinal endoscopy and total colonoscopy were performed, but no abnormalities were found within the observed area. Finally, a capsule endoscopy was performed and offered us a clue to subsequently confirm the diagnosis of inverted Meckel's diverticulum via computed tomography scan. Laparoscopic intestinal resection surgery was performed. The final pathology report described a Meckel’s diverticulum.

Since inverted Meckel's diverticulum is an uncommon disease and its clinical presentation is not specific, it may go undetected by capsule endoscopy. Successful diagnosis and treatment of this disease requires a high index of clinical suspicion.

Intusussception leading to intestinal obstruction is a known complication of Meckel's diverticulum. Inverting of Meckel's acts as a lead point for intussusception. Causes of inversion are many but surgical inversion leading to intusussception is extremely rare.

We hereby report a case of a 14 year adolescent boy operated previously for open appendicetomy presenting to us with intestinal obstruction who on exploration was found to have an surgically inverted Meckel's diverticulum acting as a lead point for ileo-colic intusussception.

To the best of our knowledge, surgically inverting any Meckel's diverticulum is never a treatment option even when the diverticulum is incidentally detected. Diverticulectomy or segmental resection is the procedure of choice for Meckel's diverticulum.

Meckel's divereticulum should never be inverted surgically. Not only it is a wrong method but also increases the risk of complications.

Meckel’s diverticulum is a common asymptomatic congenital gastrointestinal anomaly, but rarely it can present with hemorrhage. Over the last few years inverted Meckel’s diverticulum has been reported in the literature with increasing frequency as an occult source of lower gastrointestinal hemorrhage. Here, we report a case of a 54-year-old male, who was referred for surgical evaluation with persistent anemia and occult blood per rectum after a work up which failed to localize the source over 12 mo, including upper and capsule endoscopy, colonoscopy, enteroclysis, Meckel scan, and tagged nuclear red blood cell scan. An abdominal computed tomography scan showed a possible mid-ileal intussusception and intraluminal mass. During the abdominal exploration, inverted Meckel’s diverticulum was diagnosed and resected. We review the literature, discuss the forms in which the disease presents, the diagnostic modalities utilized, pathological findings, and treatment. Although less than 40 cases have been reported in the English literature from 1978 to 2005, 19 cases have been reported in the last 6 years alone (2006-2012) due to improved diagnostic modalities. Successful diagnosis and treatment of this disease requires a high index of clinical suspicion, which is becoming increasingly relevant to general gastroenterologists.

Adult intussusception due to Meckel’s diverticulum (MD) is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report two cases of intussusception due to MD in adults. A diverticulectomy using a TA stapler was performed in the first patient. In the second patient extensive fibrosis of the adjacent mesentery and thickening of jejunal mucosa were observed, so a segmental resection of the small bowel or affected ileal part and a hand-sewn anastomosis was performed. The postoperative period along with the long term follow-up was uneventful for both patients. The decision between diverticulectomy vs bowel resection can be based on the intussuscepted bowel condition. Early surgical intervention may ensure a favorable outcome.

The current work attempts to highlight the various life threatening complications of Meckel's diverticulum and to present the surgical strategies used in the emergency conditions so far in the form of a review of the works presented in the literature. Our aim behind this presentation is to cover the possible indications, methods, their complications and the outcome of these surgical techniques. For this, we made an extensive literature search using Google and Pubmed with the words-"Meckel's diverticulum", "Complications", "Management" and "Emergency surgery". All the relevant articles containing the surgical aspects of symptomatic Meckel's diverticulum till May 2008 were collected and analyzed. Meckel's diverticulum is the remains of the prenatal yolkstalk (Vitellointestinal duct). Although it generally remains silent but life threatening complications may arise making it an important structure for having a detailed knowledge of its anatomical and pathophysiological properties to deal with such complications.
