Severe ischemic cytomegalovirus proctocolitis with multiple perforation.

Cytomegalovirus (CMV) typically causes gastrointestinal infections in immunocompetent patients. Colonic perforations secondary to CMV are exceeding rare. We describe a 88-year-old male presenting with a week-long history of intractable abdominal discomfort, bloating, nausea and diarrhea.

Morning colonoscopies are associated with improved adenoma detection rates.

Background: Higher adenoma detection rates are associated with decreased risks for subsequent colorectal cancers. Studies have suggested that adenoma detection rate (ADR) may be affected by timing of colonoscopy due to endoscopist fatigue later in the day. The aim of our study is to assess the influence of the timing variables on ADR.

Unusual cause of pneumomediastinum in a laparoscopic extraperitoneal inguinal hernia repair.

Pneumomediastinum is an extremely rare complication after laparoscopic inguinal hernia repair. Very few cases have been reported in the surgical literature to date and most reports indicate pneumoperitoneum from the transabdominal preperitoneal approach as a causative factor. This case report describes a patient in whom an elective total extraperitoneal inguinal hernia repair was complicated by a pneumomediastinum without concomitant pneumoperitoneum, and identifies the tracking of air along the anterior extraperitoneal space and endothoracic fascia as a cause.
