Although duodenal diverticula are common, periampullary duodenal diverticula are rare. Periampullary duodenal diverticula are usually asymptomatic and may be difficult to diagnose and treat. However, they may present with massive bleeding, requiring prompt diagnosis.

Meckel’s diverticulum is usually asymptomatic and found in almost 2% of the population. Haemorrhage from a Meckel’s diverticulum is common in children but rare in adults. Here we report a case of 20 years old male with recurrent gastrointestinal bleeding. Meckel’s diverticulum was diagnosed due to abnormal vascularity on mesenteric angiography and embolization was performed. Diagnosis was correlated with other radiological imaging and later elective resection was performed. This case is reported to emphasize the potential role of mesenteric angiography in the detection and management of bleeding Meckel’s diverticulum and correlation with other radiological imaging.

The reported accuracy of pertechnetate scintigraphy (Meckel scan) in investigating children with a bleeding Meckel’s diverticulum has increased steadily since it was first introduced into clinical practice in 1970. Recent studies have indicated that the examination has a sensitivity of up to 94% and a specificity of up to 97% in this scenario. There have also been several misleading reviews from Departments of Surgery, suggesting that the Meckel scan has a poor predictive value, and should not be relied upon to exclude a bleeding Meckel’s Diverticulum (MD).

Quality control and technical issues are essential for high-quality imaging. An important technical parameter of image acquisition is selecting zoom factor according to camera field-of-view dimensions and patient’s body size. Here, we present a case of atypically located Meckel’s diverticulum mimicking bladder on Meckel scan.

A Meckel’s diverticulum is a common anomaly of the gastrointestinal tract. Although the majority of patients do not have any symptoms, malignancies can develop inside these diverticula, with neuroendocrine tumours being the most common. Diverticulectomy is the best option for complicated diverticula but prophylactic resection of asymptomatic diverticula in adults remains controversial. We present a case series of three patients with a neuroendocrine tumour found in a Meckel’s diverticulum. Given the number of asymptomatic diverticula not resected, it seems likely that incidental neuroendocrine tumours are more prevalent than thought previously. With the minimally invasive techniques now available and the low complication rate for incidental diverticulectomy, we believe that the benefits of resection of this high risk area for cancer outweigh the risks of surgery.

A Littre’s hernia is an unusual phenomenon where a Meckel’s diverticulum protrudes through a potential abdominal opening. We wish to present a unique case of a 79-year-old man with respiratory distress following a fall from standing, initially managed as a haemothorax. After a chest drain was placed, bowel contents were drained from the pleural cavity and he was taken to theatre. He had a history of minimally invasive oesophagectomy for cancer and had subsequently developed a diaphragmatic hernia. A blind ending diverticulum with a perforation at its tip was found in the left oblique lung fissure that was subsequently confirmed histologically as a perforated Meckel’s diverticulum. The patient had a prolonged stay on the intensive care unit with a left-sided empyema that was managed radiologically prior to discharge. Unfortunately 4 months postoperatively, he passed away from hospital-acquired pneumonia on a rehabilitation ward.

The frequent complications of Meckel’s diverticulum are hemorrhage, intestinal obstruction, and inflammation, and perforation. The presentation as a retroperitoneal abscess as complications of Meckel’s diverticulum is a very rare clinical entity.

Meckel scintigraphy with Tc-pertechnetate was performed in a 5-year-old boy to determine whether a Meckel diverticulum containing ectopic gastric mucosa caused bleeding. The images did not reveal focal activity characteristic of a Meckel diverticulum. Unexpectedly, activity in the tracheobronchial tree was visualized, consistent with aspiration of the radioactive saliva.

The Zenker diverticulum (ZD) is the most common type of esophageal diverticula. Management of ZD has different options; however, there is a recent increase in treatment with flexible endoscopic myotomy (FEM). In our study, we aimed to investigate the efficacy and safety of FEM among patients with ZD.

Jejunal diverticular (JD) disease is an uncommon occurrence that frequently present as a diagnostic dilemma. The correct diagnosis from complications of JD is typically made at laparotomy. Most JD are asymptomatic. Of clinically significant small bowel diverticula, only 15% present with surgical problems including obstruction, gastrointestinal bleed, and perforation.
