RESUMEN
The purpose of this study is to evaluate the safety and effectiveness of laparoscopic surgery by comparing laparoscopic and conventional surgery of right colonic diverticulitis (RCD). Among 124 patients who were treated for RCD from January 1997 to July 2007, we enrolled 54 patients who received resection therapy of RCD. Patients were divided into two groups: laparoscopic (LAP; n=19) and conventional (CON; n=35) surgery groups according to the respective surgical modality. The diverticulectomy (DIV; n=46) and right colectomy (COL; n=8) groups were also compared according to operative methods. There were significant differences between preoperative diagnosis and selection of the operative method and between RCD type and selection of operative method. However, there were no significant differences between preoperative diagnosis and selection of laparoscopic surgery and between RCD type and selection of laparoscopic surgery. The Kaplan-Meier estimated recurrence risk for all patients also showed no significant differences between LAP and CON and DIV and COL (P = 0.413). The Kaplan-Meier-estimated RCD-free period after surgery was 92.7 months (limited to 100 months). Laparoscopic surgery of RCD is an effective and safety method as a result of no differences in clinical data between conventional and laparoscopic surgery.
