Port complications following laparoscopic adjustable gastric banding for morbid obesity

Laparoscopic adjustable gastric banding (LAGB) has gained widespread acceptance. However, the technique has problems intrinsic to the material wear and tear around the port and connecting tubing that can lead to failure. Port complications are considered to be minor; however, few studies have analyzed them, and the optimal technique of port implantation and management has not been elucidated.

All patients who suffered from complications involving the tubing or access-port were included in this study. Their complaints, imaging studies, operative reports and hospitalization files were retrospectively reviewed.

1,272 of the patients were available for a mean follow-up period of 37 months. During this time, 91 patients (7.1%) experienced port complications that required 103 revisional operations. Of these patients, 62 had system leaks, 19 infectious problems, and 10 miscellaneous problems requiring operative correction. Overall port problems led to band removal in 6 patients, and replacement in 1 patient.

Access-port complications after the Lap-Band procedure are among the most common and annoying ones, and can render the device susceptible to failure. Careful surgical technique and routine use of radiologic guidance for band adjustments are the keys to avoiding complications.
