Background: Laparoscopic placement of an adjustable gastric band is an attractive alternative for patients who can benefit from a restrictive bariatric procedure. Creation of the retrogastric tunnel (RGT) may, however, be a considerable challenge early in the surgeon's learning curve. Recent reports described up to 10% band slippage and occasional gastric perforation associated with RGT. The two-step (TS) technique involves a crural dissection towards the angle of His through a gastrohepatic ligament approach. It facilitates passage of the band's tubing posteriorly with no wide posterior gastric wall dissection. Patients and Methods: Prospective data were registered for the 109 patients (92 females, 17 males) who underwent laparoscopic adjustable gastric banding from December 1998 to May 2000. In 11 patients the standard RGT approach was used, and in 98, the TS technique. The two groups were demographically similar. Mean age was 37 years (18-59); mean preoperative weight was 120 kg (90-165). Results: All procedures were completed laparoscopically. The mean operative time was 59 minutes (31-150) and the mean hospital stay 1.2 days (1-5). Complications in the TS group were gastric wall hematoma in one patient, 3 days of intubation post-operatively in one patient, damage to a band demonstrated in a postoperative contrast study in one patient, and a port-site hernia in one patient. There was no band slippage in the TS group. Among the 11 patients undergoing RGT, there was band slippage in three (27%), immediately postoperatively in one and after 3 and 11 months in the other two. In a mean follow-up of 7 months (1-18), similar weight loss was found in both groups. The mean BMI decreased from 44 kg/m2 (36-61) preoperatively to 40, 38, 36, 34 kg/m2 at 1, 3, 6 and 9 months respectively. 52 patients required band adjustment; of these, 12 required two adjustments. Conclusion: Our experience with both the RGT and TS techniques indicates that the latter may offer better results, particularly in the early experience period. It is recommended that in their initial experience with the adjustable band, surgeons should become familiar with this approach.
