Laparoscopy in the diagnosis and management of Crohn's disease

We have tried to evaluate the role of laparoscopy and laparoscopic-assisted surgery in the management of Crohn's disease. Over a 4-year period, we had 38 patients, of which 23 patients were suspected to have Crohn's disease and were admitted for diagnostic laparoscopy while 15 patients had already had a biopsy confirmation of Crohn's disease in the past and were admitted for specifically planned procedures. In the first group of 23 patients, 11 were found not to have Crohn's disease. In the remaining 12 patients, three were proven to have Crohn's disease, but no surgical procedure was undertaken. The remaining nine patients underwent laparoscopic-assisted procedures, of which two required conversion to a laparotomy because of intra-abdominal abscesses. All 15 patients in the second group underwent laparoscopic or laparoscopic-assisted procedures. In total, 14 patients were spared a potential diagnostic laparotomy and could go home the next day. The remaining 24 patients underwent procedures requiring longer hospital stays; five had a purely laparoscopic procedure, 17 had a laparoscopic-assisted procedure, and two required a laparotomy. Although there was little difference in the median stay for patients treated laparoscopically or by laparotomy, it is thought that the extent or severity of the disease process influenced the length of the stay rather than the approach used. The complication rate was similar to that found in Crohn's patients undergoing open surgery. It remains to be seen whether those in the laparoscopically treated group have less adhesive complications than those treated by laparotomy. It is our belief that laparoscopy is a valuable aid in the diagnosis of Crohn's disease. It remains to be proven whether or not laparoscopic-assisted surgery will be of significant value in the treatment of this condition.
