Adjustable gastric banded plication versus sleeve gastrectomy: the role of gastrectomy in weight loss.

BACKGROUND

Laparoscopic adjustable gastric banded plication (LAGBP) is a procedure that has a stomach volume similar to the sleeve gastrectomy (SG). It has shown promising results but has not been adopted widely.

OBJECTIVE

To determine the difference gastrectomy has on weight loss and complications.

SETTING

Private practice, United States.

METHODS

A retrospective, matched-cohort analysis of LAGBP and SG patients was found through matching body mass index and sex for each LAGBP to a SG patient. Body mass index, percentage excess weight loss, and total weight loss percentage were analyzed. Complication data were also collected on a short- (<30 d) and long- (>30 d) term basis. Complication rates were then compared. Data were analyzed through descriptive statistics.

RESULTS

Patients who received SG lost more body mass index, percentage excess weight loss, and total weight loss percentage at 1 year and started to gain weight between 1 and 2 years. LAGBP patients weight loss also peaked at 1 year but maintained their weight loss to year 2. SG patients lost more weight at all time points, and the difference was statistically significant (P<.05). LAGBP and SG patients had statistically similar rates of short- and long-term complication rates. In the LAGBP group (57 patients) 5, 9, 13, 14, 14, and 17 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively. In the SG group (57 patients) 11, 10, 11, 13, 20, and 29 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively.

CONCLUSION

Both procedures have peak weight loss at 1 year with acceptable complication rates. However, the SG starts to regain weight while the LAGBP shows weight stability. More time is needed to see if the weight loss curves will intersect or if the late band complications will also happen with the LAGBP as they have with band placement without plication.
