Outcomes of Reoperation After Laparoscopic Gastric Plication Failure.

backgroundManagement of failed laparoscopic gastric plication (LGP), defined as weight regain or inadequate weight loss, is a challenging issue.

methodsThis prospective investigation was conducted in individuals with morbid obesity who had undergone LGP from 2000 to 2016. Patients with weight loss failure, weight regain, and regain-prone cases were indicated for reoperation. Re-plication, laparoscopic one anastomosis gastric bypass (LOAGB), and modified jejunoileal bypass were done as revisional surgery.

resultsRevisional surgery was performed in 102 of 124 patients who needed reoperation. Overall, 39 re-plication, 38 LOAGB, and 25 malabsorptive procedures were performed. Re-plication was the shortest surgery and had the shortest length of hospital stay. The percentage of TWL at 6, 12, and 24 months of follow-up was 20.5%, 25%, and 26.8% for re-plication; 20.2%, 27%, and 30.5% for LOAGB; and 22.9%, 28.9%, and 32.6% for the malabsorptive procedure, respectively. In addition, the percentage of EWL at 6, 12, and 24 months of follow-up was 62%, 74.6%, and 79.6% for re-plication; 51.6%, 68.2%, and 75.9% for LOAGB; and 55.4%, 70.1%, and 79.1% for malabsorptive procedure, respectively. In long-term follow-up, according to %TWL, LOAGB and malabsorptive procedure had better outcome compared to re-plication, whereas there was no statistically significant difference in %EWL among the three surgical approaches.

conclusionsIn terms of weight loss, reoperation on failed LGP was completely successful and no treatment failure was reported. All three revisional procedures, including re-plication, LOAGB, and malabsorptive procedure showed promising results and provided substantial weight loss. Since there is little information about the long-term efficacy and safety of revisional surgery on failed LGP, we highly recommend further investigations to confirm our results.
