High-resolution sonography of the undescended testis in childhood: an analysis of 45 cases.

A prospective study correlating the ultrasound and operative findings was carried out in 45 consecutive pediatric patients with undescended testes. Thirty-six of 37 (97%) palpable testes were located preoperatively by ultrasound. Six of eight impalpable testes (75%) were correctly localized by ultrasound.

Isolated gallbladder rupture due to blunt abdominal trauma.

Traumatic injury to the extrahepatic biliary system is rare and usually diagnosed at laparotomy when it is associated with other visceral injuries. Isolated gallbladder rupture due to blunt abdominal trauma is even rarer. The clinical presentation of gallbladder injury is variable, resulting in a delay in diagnosis and treatment.

The feasibility of in vivo resection of the left lobe of the liver and its use for transplantation.

The anatomical possibility of resecting the left lobe of the liver (segments II and III) in living subjects and using it for transplantation was evaluated. A group of 60 cadaveric livers were dissected at autopsy. The vascular and biliary elements of the left lobe were isolated and the lobe was resected and evaluated for possible grafting.

Jejunogastric intussusception. A new diagnostic test.

Jejunogastric intussusception is a rare complication of gastrojejunal reconstruction of unknown cause. There are two types of jejunogastric intussusception: the acute type, presenting as a surgical emergency, and the chronic intermittent type, which is difficult to diagnose and is usually of mild symptomatology but which may progress to the acute type with the incarceration of the intussusceptum. With two case reports and a literature review, an endoscopic diagnostic maneuver is proposed, hinting at disordered motility with reversed peristalsis as a possible causative factor.
