Location and number of sutures placed for hiatal hernia repair during laparoscopic adjustable gastric banding: does it matter?

BACKGROUND: It has been demonstrated that hiatal hernia repair (HHR) during laparoscopic adjustable gastric banding (LAGB) decreases the rate of reoperation. However, the technical aspects (location and number of sutures) are not standardized. It is unknown whether such technical details are associated with differing rates of reoperation for band-related problems. METHODS: A retrospective analysis was performed from a single institution, including 2,301 patients undergoing LAGB with HHR from July 1, 2007 to December 31, 2011. Independent variables were number and location of sutures. Data collected included demographics, operating room (OR) time, length of stay (LOS), follow-up time, postoperative BMI/%EWL, and rates of readmission/reoperation. Statistical analyses included ANOVA and Chi squared tests. Kaplan-Meier, log-rank, and Cox regression tests were used for follow-up data and reoperation rates, in order to account for differential length of follow-up and confounding variables. RESULTS: There was no difference in length of follow-up among all groups. The majority of patients had one suture (range 1-6; 55 %). Patients with fewer sutures had shorter OR time (1 suture 45 min vs. 4+ sutures 56 min, p < 0.0001). LOS, 30-day readmission, band-related reoperation, and postop BMI/%EWL were not statistically significant. Anterior suture placement (vs. posterior vs. both) was most common (61 %). OR time was shorter in those with anterior suture (41 min vs. posterior 56 min vs. both 59 min, p < 0.0001). Patients with posterior suture had a longer LOS (84 % 1 day vs. anterior 74 % 1 day vs. both 74 % 1 day, p < 0.0001). There was no difference in 30-day readmission, band-related reoperation, and postoperative BMI/%EWL. CONCLUSIONS: Patients with fewer or anterior sutures have shorter OR times. However, 30-day readmission, band-related reoperation, and postoperative weight loss were unaffected by number or location of suture. The technical aspects of HHR did not appear to be associated with readmission or reoperation, and therefore a standardized approach may not be necessary.
