Periampullary carcinoma presenting as duodenojejunal intussusception: a diagnostic and therapeutic dilemma.

Background: An intussusception is the invagination of one segment of the intestine into another. It is more common in children, but a rare clinical entity in adults, where the condition is almost always caused by tumors.

Methods: A 51-year-old female presented with symptoms of gastric outlet obstruction associated with significant weight loss, but no jaundice.

Chylous ascites after pancreatico-duodenectomy cholangiocarcinoma xenografts in nude mice.

Background: Chylous ascites (CA) following pancreatico-duodenectomy (PD) is a rare complication secondary to disruption of the lymphatics during extended retroperitoneal lymph node dissection. The majority of cases do not develop CA, possibly due to patency of the proximal thoracic duct and good collaterals. CA may be due to a consequence of occult obstruction of the proximal thoracic duct by malignant infiltration or tumor embolus.

Pseudoaneurysm following laparoscopic cholecystectomy.

Background: Laparoscopic cholecystectomy (LC) is the operation of choice for removal of the gallbladder. Unrecognized bile duct injuries present with biliary peritonitis and systemic sepsis. Bile has been shown to cause damage to the vascular wall and therefore delay the healing of injured arteries leading to pseudoaneurysm formation.

Staged resection for a ruptured hepatoblastoma: a 6-year follow-up.

Hepatoblastoma (HB) is a rare germ cell tumour of childhood usually presenting with progressive abdominal distention. However, presentation as acute abdomen is a rare occurrence and is secondary to spontaneous rupture. This presentation carries high mortality.
