BackgroundPrevious experimental studies have repeatedly demonstrated the potential protective effect of remote ischemic preconditioning (IPC) on colon anastomosis. The purpose of this experimental study was to investigate the possible positive effects of IPC by interval insufflations in laparoscopic colon operations.MethodsThirty Wistar-albino rats were randomized into 3 groups. Colonic transsection and anastomosis were performed in the control group. In the laparoscopic colon operation without IPC group, the intra-abdominal pressure was raised to 14 mm Hg for 60 minutes, and then laparotomy and colonic anastomosis were performed. In the IPC group, the intra-abdominal pressure was raised to 14 mm Hg for 5 minutes, followed by desufflation. Laparotomy and colonic anastomosis were performed exactly as in the non-IPC group. On the seventh postoperative day, all animals were killed, and blood and tissue samples were obtained. Anastomotic healing and inflammatory responses were determined by histopathologic examination and by measuring the anastomotic bursting pressure, tissue hydroxyproline level, and tissue and serum nitric oxide, malondialdehyde (MDA), and catalase activity levels. Differences with P-values of <0.05 were considered to be statistically significant.ResultsAlthough the best anastomotic healing was detected in the control group, anastomotic healing was better in the IPC group than that in the non-IPC group. In terms of anastomotic bursting pressure, plasma MDA, serum catalase activity, and tissue nitric oxide levels, the IPC group was superior to the non-IPC group. No significant differences were found between the control and IPC groups, except in the plasma MDA levels.ConclusionsUse of IPC with colon anastomosis had positive effects on wound healing and may serve as a safe method to reduce the adverse effects of ischemia and wound healing in laparoscopic colon operations.
