Second Laparoscopic Colorectal Resection: Safety and Feasibility.

ABSTRACT

BACKGROUND: As laparoscopic colorectal surgery continues increasing worldwide, the need of having a second laparoscopic colorectal resection (SLCR) might increase as well. Experience with this challenging procedure is scarce. The aim of this study was to evaluate the safety and feasibility of SLCR. METHODS: A retrospective analysis of a prospectively collected database of patients undergoing colorectal surgery who needed an SLCR during the period 2008-2020 was performed. Demographics, operative variables, and postoperative outcomes were analyzed. A propensity score matching with a control population undergoing a first elective colorectal resection was performed. RESULTS: A total of 1918 patients underwent colorectal surgery and 32 patients (1.7%) who required a SLCR were included for analysis; 17 (53.1%) were male, and the mean age was 71 (39 to 89) years. The median time between the first and second operations was 69 (6 to 230) months. At the second resection The median operative time was 170 (90 to 380) minutes, there were 3 (9%) intraoperative complications and 2 (6%) conversions. Overall postoperative morbidity and major morbidity rates were 34% and 19%, respectively. Four patients (12.5%) required reoperation and 1 (3.1%) died of septic shock after an anastomotic leak. After propensity score matching, SLCR was more frequently performed by colorectal surgeons, and no differences in perioperative variables were observed compared with the control group. CONCLUSIONS: SLCR can be safely performed without jeopardizing perioperative outcomes. Further studies are needed to confirm the benefits of the minimally invasive approach in colorectal second resection and to elucidate the long-term outcomes.
