Preventing port site inversion in laparoscopic adjustable gastric banding



      Laparoscopic adjustable gastric banding (LAGB) is a safe, controlled method for weight loss in the morbidly obese patient. Inversion or dislodgement of the port leads to difficulty with access for band adjustments and frequently requires reoperation. We report our experience with port fixation to the rectus sheath of the abdominal wall by using port/mesh fixation to prevent port site complications.


      One hundred and ninety-one morbidly obese patients underwent LAGB between April 2002 and August 2005. The first group had ports fixed to the rectus fascia of the abdominal wall with a standard 4-point suture technique. The second group had ports sutured to a mesh, which was then tacked to the rectus sheath of the abdominal wall. Port site complications were analyzed over a 5-month to 40-month period and compared between the 2 groups. Intraoperative port fixation times were recorded for each technique.


      Thirty-nine patients in the suture fixation group encountered a 20.5% port site complication rate, with 10.3% of the ports becoming dislodged or inverted. The mesh/tack group consisted of 151 patients. The port site complication rate was 5.3%, with only a 1.3% rate of port dislodgement or inversion. The port dislodgement or inversion rates were significantly different between groups (P = .0049). The average operative times for port insertion were 12 minutes for the sutured technique and 5 minutes for the mesh/tack technique.


      The mesh/tack method of port fixation reduced the incidence of dislodgement and rotation in our patient population, which resulted in greater ease of access for adjustments. Furthermore, the mesh/tack technique is a quick, safe approach for port fixation through a small incision.
