Abstract

INTRODUCTION: Small colonic tumor localization and correct extension of colonic resection is critical in laparoscopic surgery. Currently used techniques are sometimes inconclusive and may carry some morbidity. We describe an original method of small tumor localization during laparoscopic colorectal operations through the use of preoperative clip applications by colonoscopy and intraoperative ultrasound of the colon. METHODS: Eight patients with small colonic lesions necessitating preoperative marking were included into this study. A two-step technique was used. Before the operation two metal clips were endoscopically applied proximally and distally to the lesion site. At surgery an intraoperative ultrasound examination of the colon or rectum surface was performed to localize the clips. Subsequent laparoscopic colon resection was performed. RESULTS: Endoscopic metallic clips were easily applied around the lesion in all cases without complications. No dislodgement of clips was documented. At surgery laparoscopic ultrasound visualized the clips in all cases. The examination took between 5 and 17 minutes with no specific morbidity. The lesions with the surrounding clips were always found in the resected specimen. CONCLUSIONS: Endoscopic metal clipping and intraoperative laparoscopic ultrasound proved to be an easy, safe, and accurate technique in locating small colonic tumors.
