Video-assisted versus open ileocolic resection in primary Crohn's disease: a comparative case-matched study

Despite the technical difficulties, laparoscopic ileocolic resection for Crohn's disease (CD) has become widely accepted in recent years, due to its potential benefits. There are numerous reports concerning the use of laparoscopy in successfully treating CD, including two randomized trials and few comparative studies. For the most part, these reports outline use of laparoscopic approach in primary distal ileal or ileocolic disease, with a careful selection of the patients. The purpose of this comparative case-control study was to point out potential advantages and disadvantages in short- and long-term outcomes of the laparoscopic approach compared with the open one. From January 1999 to January 2004, 200 patients were admitted in our Surgical Unit for complicated primary CD. 100 patients (group 1) underwent a laparoscopic ileocolic resection, 100 patients (group 2), with alike demographic and clinical characteristics, underwent the same procedure using a traditional approach. The incidence of perforative disease was 32 and 40% in groups 1 and 2, respectively. Average operative time was 140 min (range 90-245 min) in the video-assisted group and 98 min (range 65-255 min) in group 2 (P < 0.05). Postoperative morbidity was 6 and 8% in groups 1 and 2, respectively (P = NS). Recovery of peristalsis occurred within 2-3 days in group 1 and 3-4 days in group 2 (P = NS). Median postoperative hospitalization was 7 days (range 5-18 days) in group 1 and 9 days (range 7-22 days) in control group (P < 0.05). The overall rate of surgical relapse of CD was 8 and 13% in groups 1 and 2, respectively (P = NS), at a mean follow-up of 52 and 60 months, respectively. The 1-year surgical recurrence rate was similar (3%) for the two groups. In conclusions, in spite of the technical difficulties, video-assisted surgery for CD offers advantages over laparotomy, including less postoperative pain, reduced postoperative hospital stay, less disability of the patient, and better cosmetic results. Potential advantages are: easier approach for re-resection, lower rate of postoperative adhesions and bowel obstruction, and lower rate of wound complications.
