Single-Incision Laparoscopic Placement of an Adjustable Gastric Band versus Conventional Multiport Laparoscopic Gastric Banding: A Comparative Study

Abstract

Single-incision laparoscopic surgery (SILS™) is rapidly becoming the focal point of attraction for early adopters of minimally invasive surgery nationwide. Having achieved a rapid crossover to the realm of advanced surgical procedures, SILS™ has shown remarkable versatility and adaptability, making it no longer limited to basic laparoscopic procedures. We report our experience performing laparoscopic placement of gastric bands with an emphasis on comparison of the single-incision laparoscopic approach with the conventional multiport laparoscopic approach. From December 2008 to September 2009, 27 patients underwent laparoscopic placement of an adjustable gastric band at Michigan State University/Kalamazoo Center for Medical Studies. This included 15 patients who underwent single-incision laparoscopic gastric banding and 12 patients who underwent conventional multiport laparoscopic gastric banding procedures. The overall pain score was found to be significantly less in the SILS group than that for the conventional multiport laparoscopic gastric banding group with a statistically significant P value of 0.012. The operating time was found to be significantly less in the multiport group with a P value of 0.000. Differences in immediate postoperative pain scores, analgesia, and the overall length of hospital stay were found to be statistically insignificant. Single-incision laparoscopic gastric banding is associated with significantly less overall postoperative pain than the conventional laparoscopic approach; in addition, it provides improved cosmetic outcome despite a modest increase in operative time.
