PURPOSE: The advent of laparoscopic surgery has altered the manner by which surgical specialties address pathologies of the abdominal cavity. This advance in technology has also changed colorectal surgery. One of the more common procedures of colorectal surgery is segmental resection for polyps that are large, broad based, or inaccessible for colonoscopic removal. We present a technique combining colonoscopy and laparoscopy to remove troublesome polyps without the need for segmental resections. METHODS: From May 1990 to September 1999 laparoscopic-monitored colonic polypectomies were performed in 47 patients, with a total of 60 polyps being removed. After laparoscopic mobilization of the involved segment of the colon, the proximal bowel is cross-clamped and the colonoscope passed to the involved portion of the colon. The polyp is then presented to the colonoscopist by the laparoscopist facilitating removal. The serosal surface is monitored for any indications of transluminal injury, and the area is repaired if needed. All polyps undergo immediate frozen section analysis. If the pathologic evaluation indicates malignancy then a segmental resection may be performed, otherwise the patients are decompressed and fed within a short time before discharge. RESULTS: The polyps were located most commonly in the ascending colon (18 polyps), transverse colon (12 polyps), and cecum (12 polyps). The most common histopathologic diagnosis was tubulovillous adenoma in 28 polyps followed by villous adenoma in 11 polyps. In three cases histopathologic diagnosis revealed malignancy necessitating segmental resection (1 low anterior resection and 2 right hemicolectomies), which were performed laparoscopically. Patients received a liquid diet within 6 hours, were discharged in an average of 21 hours, and returned to full activity, usually within days. The only complication presented in this group of patients was an umbilical port seroma. Virtually all patients (97 percent) behaved as if only a colonoscopy had been performed. Pain at the trocar sites was managed with acetaminophen 600 mg by mouth as needed. CONCLUSION: Laparoscopic-monitored colonoscopic polypectomy allows patients to undergo removal of colonic polyps without a segmental resection. This less invasive procedure yields recovery times similar to that of colonoscopy alone, and the potential complications of a segmental resection are avoided. All polyps are examined by frozen section, and if a malignancy is encountered, a laparoscopic resection can be performed.
