Laparoscopic adjustable gastric banding: a prospective comparison of two commonly used bands.
BACKGROUND
Surgery for morbid obesity has increased since the introduction of the adjustable gastric bands (AGB), which can be placed laparoscopically. There are two AGB in wide use: the Swedish Adjustable Gastric Band (SAGB, Obtech), and the Lap-Band (Inamed Health). We present the results of a comparative study between the 2 AGB.


METHODS
101 patients with a minimal follow-up of 6 months were included. 49 patients received a Swedish Adjustable Gastric Band (SAGB), and the remaining 52 received the Lap-Band (LB). Postoperative weight loss and complications were compared at set intervals of 3 months in the first postoperative year, and 6 months in the years following.


RESULTS
Mean follow-up was 9.9 months for the SAGB and 7.2 months for the LB. All but 5 procedures were performed laparoscopically. Mean operating-time was 102 minutes for the SAGB and 86 minutes for the LB. No significant difference in complications was noted between the 2 AGB. 1 SAGB was repositioned and 2 were removed, compared to 2 repositions and 2 removals of the LB. We excluded 5 patients with leakage of a SAGB due to technical failure. Mean preoperative weight kg/BMI of the SAGB patients was 133/45.3; in the LB patients 138/46.4. Mean weight loss at 6 months was 28 kg with the SAGB and 30 kg with the LB, and mean weight loss at 1 year 36 kg and 38 kg respectively. After 2 years, weight loss was 46 kg and 42 kg respectively.


CONCLUSIONS
There was no significant difference in postoperative weight loss and complications between the SAGB and the LB.
