Single incision laparoscopic bariatric surgery has developed over the last few years, with single incision laparoscopic adjustable gastric banding (SILS-AGB) being performed most commonly. However, there are no randomised controlled trials and few matched studies comparing SILS-AGB to conventional laparoscopic multi-port multiport adjustable gastric banding (LAGB). Our aim was to study any differences in outcome and analgesic requirements between two matched groups of gastric band patients (SILS-AGB and LAGB).
Between June 2009 and September 2010, 111 patients underwent SILS-AGB and 99 patients underwent LAGB performed by a single surgeon (AGP). Patients were matched for age, sex, weight, BMI and co-morbidities. Forty six SILS-AGB and LAGB patients were included for analysis. Their outcomes were compared for operating times, conversions, analgesia requirements, morbidity and mortality.
Patients characteristics between the SILS-AGB and LAGB groups were similar with no differences in their median age (44 vs 47 years), sex (m:f; 7:39 vs 4:42), body mass index (43.1 vs 44.4 kg/m2) or co morbidities respectively. In the SILS-AGB group the median operating time (70 min) was not significantly longer than in LAGB group (61.5 min, p = 0.07). However, SILS-AGB patients used less opiates (p < 0.01) than the LAGB patients. There was no difference in morbidity, mortality or readmission rates.
SILS-AGB is a safe and feasible option and is comparable with LAGB. Post operative demand for analgesia was significantly less in the SILS-AGB group. Further comparisons of post operative pain and long term outcomes are required; however preliminary results are promising.
