Single-incision surgery in the morbidly obese patient has not been widely adopted, but remains a popular choice amongst patients. In the bariatric patient, it presents its own surgical challenges with hepatomegaly and increased abdominal adiposity. Here, we present our experience of 275 single-incision laparoscopic gastric bands.Between June 2009 and April 2013, 275 obese patients underwent single-incision laparoscopic adjustable gastric banding through a single incision using a multichannel single port and via a pars flaccida approach. Prospective data collection was undertaken including operating time, additional ports and additional procedures undertaken.In this series, median operative time was 60 (range 34–170) min. An additional port was placed in 15 patients (5 %), including two conversions to four-port technique (0.7 %). Of these patients (n = 15), the majority were male (p < 0.0001). Reasons for additional port placement included bleeding and anatomical abnormalities. Additional port placement occurred more often within the first 50 cases (5/50, 10 % vs 10/225, 4 %). An umbilical incision resulted in more wound-related complications than a transverse incision in the upper abdomen (p < 0.001). There were no 30-day mortality and minimal morbidity with two wound infections resulting in band removal.Single-incision laparoscopic adjustable gastric banding can be performed safely with minimal morbidity in the morbidly obese patient, and our technique has a high rate of success for all BMIs. Following 275 single-incision band insertions additional port placements were more commonly required in male patients, BMI >45 and earlier in the learning curve.
