Effects of minimizing access trauma in laparoscopic colectomy in patients with IBD.

Background: Laparoscopic interventions to minimize access trauma are increasingly gaining importance for both cosmetic reasons and lower postoperative morbidity. The aim of this study was to compare the clinical outcomes for different laparoscopic colectomy and proctocolectomy accesses considering IBD. A comparison was made between total laparoscopic (LR)-without an extra incision for sample--and laparoscopic-assisted resection using a small incision for retrieval of the specimen (LAR) PATIENTS AND METHODS: From 2006 to 2012, 109 IBD patients underwent minimal invasive total colectomy or proctocolectomy. Patients were subdivided according to access into LR and LAR. Perioperative outcomes were evaluated.

Results: 86 patients with Ulcerative Colitis (UC) and 23 with Crohn's disease (CD) were included (LR: 64 UC/13 CD, LAR: 22 UC/10 CD). Among them, there were no differences in age, BMI, sex, ASA score or pre-existing immunosuppression. Patients with LR and UC had a higher disease activity score (Truelove III LR: 42 %, LAR: 5 %; p = 0.005). The Crohn's Disease Activity Index did not differ. Patients with LR had a shorter operating time (LR: 211.5, LAR: 240 min; p = 0.002). There was no significant difference in hospital stay (LR: 11, LAR: 12.5 days; p ≥ 0.05), length of stay at the ICU (both 1 days; p ≥ 0.05), duration of required analgesia (LR: 7 days, LAR: 8 days; p ≥ 0.05), and nutritional build-up (both 5 days; p ≥ 0.05). Groups had the same overall complication rate, but surgical site infection rates tended to be higher in patients with LAR (LR: 9.1 %, LAR: 21.9 %, p = 0.07).

Discussion: Laparoscopic procedures for colectomy and proctocolectomy are safe and effective techniques for patients with colon involvement and IBD. Minimizing the access trauma in laparoscopic colectomy offers a potential advantage of reduced surgical site infections, especially for frequently immunosuppressed IBD patients.
