Prospective evaluation of laparoscopic-assisted colectomy in an unselected group of patients.

Laparoscopic technology is likely to have an increasing impact on surgical procedures that have previously required an open approach. We have prospectively evaluated laparoscopic colectomy in 40 patients requiring elective colonic excision mainly for malignant disease. 33 of 40 patients had a successfully completed laparoscopic colectomy, although there was one postoperative death. Seven operations were unsuccessful and required conversion to conventional open laparotomy. Morbidity was low with no wound infections and only two chest infections in the 32 survivors. Early mobilisation and discharge from hospital (mean 8 days) was a notable feature. Previous abdominal surgery was not an absolute contraindication to laparoscopic colectomy. However, the inability to palpate the colon directly to confirm the site of laparoscopically impalpable lesions leads us to recommend contrast radiology to confirm the location of colonoscopically diagnosed lesions before laparoscopically assisted colectomy. Preliminary pathological assessment of resected tumour specimens revealed a satisfactory tumour clearance. We conclude that laparoscopic colectomy is a feasible operation in most patients and leads to a substantial patient benefit without compromising the chance of a surgical cure of cancer.
