Acute obstruction of the afferent loop caused by an enterolith.

Afferent loop obstruction is a relatively rare but significant complication of Billroth II gastrojejunostomy. We report the imaging findings in a patient in whom obstruction presented acutely and was due to the presence of an enterolith. CT showed dilatation of both the main pancreatic duct and the biliary ducts, and a markedly dilated afferent loop within which a 5-cm mass was present.

Pouch diverticula after vertical-banded gastroplasty.

Purpose: Diverticula of the proximal gastric pouch are rare after vertical-banded gastroplasty (VBG) for morbid obesity. We report the radiographic findings observed in a series of 12 patients with pouch diverticula.

Materials And Methods: Lesions were found along the posteromedial wall of the proximal gastric pouch and ranged in size from 10 to 25 mm.

Benign lymphoepithelial parotid lesions in vertically HIV-infected patients.

Benign lymphoepithelial parotid lesions (BLL) are frequently reported in HIV-infected patients, although their clinical and prognostic significance in HIV infection has not been clearly defined. Ultrasonography (USG) has been shown to be a reliable method in monitoring the progression of such lesions. The purpose of this study was to describe the spectrum of sonographic and Doppler findings and to monitor any clinically evident physical change of parotid glands in a cohort of congenitally HIV-infected patients taking antiretroviral therapy.

Crohn disease obstruction of the biliopancreatic limb in a patient operated for biliopancreatic diversion for morbid obesity.

Although rare, patients with biliopancreatic diversion for morbid obesity will be subject to obstruction of the biliopancreatic limb. This condition is commonly due to postoperative adhesions and intussusception and usually presents with misleading clinical and radiographic features that can delay the diagnosis and the treatment. We recently encountered a patient with obstruction of the biliopancreatic limb due to involvement from Crohn disease.

Thirteen years of follow-up in patients with adjustable silicone gastric banding for obesity: weight loss and constant rate of late specific complications.

Background: Despite its simplicity, safety and good short-term results, progressive weight regain and a high incidence of complications have been reported after the adjustable silicone gastric banding (ASGB). The aim of this study is to evaluate the long-term results of this operation in our patient population.

Methods: Between 1990 and 1996, 45 morbidly obese patients underwent insertion of an ASGB.
