Abstract

We reviewed the radiological findings in 45 morbidly obese patients (weight range 80-129 kg; mean 95.7 kg) after gastric restriction surgery with adjustable silicone gastric banding (ASBG) according to the Kuzmak technique. Radiographic studies of the stomach were performed before, and at 4 and 12 months after surgery; symptomatic patients underwent additional studies when needed. Patients were evaluated using both liquid barium and a solid opaque meal to assess post-operative gastric morphology as well as emptying time of the proximal gastric pouch. 27 patients had a normal clinical course. Variation of the calibre of the silicone band under radiographic guidance was required in 12 of these patients, based on dilatation of the proximal pouch, variation of the stomal calibre from operative values, or an emptying time longer than 30 min. All these problems disappeared after the adjustment manoeuvres. 18 patients had complications, of which five had stomal stenosis which could not be managed through simple deflation of the band; two had posterior bending and dilatation of the proximal pouch; four had gastritis and oesophagitis; six had infection of the inflatable reservoir; one had cranial displacement of the band, and two had migration of the band into the stomach. Removal of the gastric band was necessary in 11 cases, and removal of the reservoir alone had to be performed in three additional patients. Radiology plays an important role in evaluating complications after gastric restriction surgery. Knowing the variety of findings enables accurate treatment planning and follow-up of these patients.
