Can laparoscopic surgery prevent incisional hernia in patients with Crohn's disease: a comparison study of 750 patients undergoing open and laparoscopic bowel resection.

BACKGROUND: Incisional hernia (IH) is a frequent occurrence following open surgery for Crohn's disease (CD). This study compares the IH rates of patients with CD undergoing open versus laparoscopic bowel resection. METHODS: Seven hundred and fifty patients with CD operated by the authors at the Mount Sinai Medical Center, New York, USA, were reviewed from a prospectively maintained surgical database. Five hundred patients with Crohn's disease undergoing open surgery were compared to 250 patients undergoing laparoscopic bowel resection. RESULTS: The mean duration of follow-up in the study population was 6.8 years. Patients undergoing open surgery had a significantly higher age at onset of disease, age at surgery, longer duration of disease, lower serum albumin, history of multiple previous resections, were more likely to be on steroids, needed more blood transfusions, and had an increased necessity for an ileostomy during resection. Nevertheless, the incidence of IH at 36 months was nearly identical in both groups (10.8 vs. 8.4% for open vs laparoscopic). 16% of the patients in the laparoscopic group (range: 7-20%) required conversion to open surgery. Patients undergoing laparoscopic resection that required conversion to open surgery had the highest IH rate at 18%. There was a significant correlation between IH and the length of the midline vertical extraction incision. Patients undergoing laparoscopic resection with intracorporeal anastomosis and small transverse or trocar site extraction incisions had no IH. CONCLUSIONS: A marked decrease or complete elimination of IH in patients with CD undergoing bowel resection may be possible using advanced laparoscopic techniques that require intra-abdominal anastomosis and use of the smallest transverse extraction incisions.

Laparoscopy in Crohn's disease.

Crohn's disease represents a challenging operative dilemma. The nature of the disease increases the technical complexity of operations, their morbidity, and the likelihood of multiple operations. In this setting, the advantages of laparoscopic surgery, including shorter hospital stays, less adhesion formation, fewer wound complications, and faster recovery of bowel function, are particularly beneficial to the patient. Patients with Crohn's disease requiring operations in the elective and semi-elective setting can all be approached initially laparoscopically. The surgeon's skill set should include extensive experience in advanced laparoscopic bowel surgery as well as open management of Crohn's disease and its complications. Strict adherence to the basic tenet of bowel preservation is imperative. The operations most commonly performed for Crohn's disease include diagnostic laparoscopy, stricturoplasty, small bowel resection, ileocolic resection, colectomy, repair of fistulae, and gastrojejunostomy for bypass of gastric or duodenal disease. Postoperative management includes resumption of steroids, typically without the need for "stress-dosing," bowel rest for a short period, and pain control, which is also less than that experienced with a laparotomy.
