The aim of current single-center study was to compare the short-term outcome of suction and gauze wiping alone versus the irrigation and suction technique for peritoneal decontamination among patients who underwent laparoscopic repair of PPU. Using data from our institution's prospectively maintained database, 105 patients who underwent laparoscopic repair were enrolled in this study. The participants were further divided into the group who received peritoneal irrigation (irrigation group, n = 67) and group who received gauze wiping and suction only (suction only group, n = 38). The irrigation group had a longer operative time (140 vs. 113 min, p = 0.0001), higher number of drainage tubes (38.8% vs. 0%, p < 0.0001) and a higher incidence of intra-abdominal abscess (10.4% vs. 0%, p = 0.0469) than the suction only group. Peritoneal irrigation may be associated with a prolonged operative time and a higher number of abdominal drains. Meanwhile, gauze wiping and suction may be sufficient for peritoneal decontamination during the laparoscopic repair of PPU as further infectious complications are not observed.
