Laparoscopic vs conventional ileocolectomy for primary Crohn disease

Hypothesis: Laparoscopic ileocolectomy can reduce the length of hospital stay and hospital charges compared with conventional surgery in the treatment of primary Crohn disease. Design: Nonrandomized, comparative, retrospective analysis of a prospective database. Setting: University hospital tertiary care center for. inflammatory bowel disease. Patients: Forty patients, 20 in the laparoscopic group (group A) and 20 in the conventional group (group B). Intervention: From July 1, 1996, to June 30, 200 1, we collected data on the following demographic clinical end points: age, sex, duration of disease, preoperative medical treatment, previous abdominal surgery, procedure performed, conversions to open surgery, operating time, number of trocars used, size of incision, blood loss, time to resolution of ileus, time to starting solid food diet, duration of hospital stay, hospital charges, morbidity, and mortality. Main Outcome Measures: Surgical results, length of hospital stay, hospital charges, and recurrences. Results: The mean age of the patients was 34.7 years (range, 20-68 years) in group A vs 40.0 years (range, 18-75 years) in group B. The male-female ratio was 1:2 in group A vs 1: 1 in group B. The morbidity was 5% in group B. There was no mortality. Operating time was longer in group A (mean, 145.0 minutes; range, 45-270 minutes) compared with group B (mean, 133.5 minutes; range, 98177 minutes) (P=.36). Blood loss was significantly higher in group B (mean, 265.5 mL; range, 100-400 mL) compared with group A (77.2 mL; range, 25-350 mL) (P<.001). Also, the size of the incision was significantly longer in group B (mean, 13.5 cm; range, 8-18 cm) compared with group A (mean, 5.5 cm; range, 3-12 cm) (P<.001). Bowel function returned more quickly in the laparoscopic group vs the conventional group in terms of return of bowel movements (1.70 vs 2.63 days) (P<.001) and resumption of a regular diet (1.35 vs 2.73 days) (P<.001). The mean length of stay was significantly shorter in the laparoscopic group (4.25 days) vs the conventional group (8.25 days) (P<.001). The mean hospital charges were US $9614 in group A vs US $17079 in group B (P<.05). The mean follow-up was 17.2 months in group A (range, 2.3-59.9 months) vs 18.7 months in group B (range, 1.0-37.5 months). Conclusions: Laparoscopic-assisted ileocolectomy for primary Crohn disease of the terminal ileum and/or cecum is safe and successful in most cases. Laparoscopic surgery for Crohn disease should be considered as the preferred operative approach for primary resections.
