Laparoscopic adjustable gastric banding with duodenal switch for morbid obesity: technique and preliminary results

Abstract

Background: The procedure of choice for morbid obesity remains controversial. One of the most effective treatments is the biliopancreatic diversion with duodenal switch (BPD/DS), which is, however, associated with a significant morbidity rate. Adjustable gastric banding (AGB) by the laparoscopic approach is an easier procedure with the intent to reduce complication rates. It replaced the sleeve gastrectomy in this study. The objective was to assess the feasibility and safety of this new laparoscopic treatment.

Methods: AGB with duodenal switch (DS) was performed laparoscopically with 7 trocars. A gastric band was appropriately placed below the gastroesophageal junction, followed by BPD/DS with a 250-cm alimentary channel and a 100-cm common channel.

Results: All 5 patients were women, with mean preoperative BMI 52.2 kg/m(2) (40.6 to 64.4). The operations were performed via laparoscopy in a mean of 206 +/- 35 minutes. There was no postoperative complication, infection or conversion. Mean hospital stay was 8.8 days (8-11). At 12 months, mean BMI is 35.8 kg/m(2) (26.1-46.0), with continuing weight loss and no hypoalbuminemia.

Conclusions: These data suggest that laparoscopic AGB/DS is feasible, with a low morbidity rate. This technique could combine the long-term weight loss of malabsorptive procedures, with a low-morbidity, adjustable, restrictive procedure. This technique could be used in selected patients, but requires a larger study with longer follow-up.
