Agenesis of gallbladder-an unexpected absence in laparoscopy.

Gallbladder agenesis is a very rare condition, majority of which are normally diagnosed intraoperatively because of low index of suspicion and high rate of false positive results for cholecystitis on ultrasound imaging. We present a case of a 25-year-old man who presented with a right upper quadrant pain, whose ultrasound suggests a contracted gallbladder with gallstones. He was treated as an acute on chronic cholecystitis and booked for laparoscopic cholecystectomy.

A rarer cause of Bouveret syndrome - A case report.

Introduction And Importance: Bouveret syndrome is a rare type of gallstone ileus causing gastric outlet obstruction with high morbidity and mortality risk, and hence important to have a high degree of clinical suspicion on presentation for prompt diagnosis and management.

Case Presentation: We present a case of an elderly woman with abdominal pain, haematemesis, and an unremarkable radiograph whose initial emergent endoscopy showed a gastric obstruction and a duodenal diverticulum with a non-bleeding broad based duodenal ulcer. Subsequent computerised tomographic (CT) scan revealed a cholecystoduodenal fistula and gastric outlet obstruction secondary to a 5 cm stone in the duodenojejunal (DJ) flexure.

Case report: Heterotopic pregnancy - A very unlikely cause of haemoperitoneum in trauma setting.

Heterotopic pregnancy is a rare occurrence whereby a concurrent intrauterine and extrauterine pregnancy exists. It is a difficult diagnosis to make early, and often associated with significant morbidity and mortality from complications if diagnosed late. In this report, we present a rare case of heterotopic pregnancy in a 25-year-old woman who presented with abdominal pain following blunt abdominal trauma, and ultrasound showing haemoperitoneum and a viable intrauterine 10-week gestation.
