Abstract
OBJECTIVE: The major barrier to transumbilical endoscopic surgery is external interference between the instrument handles around the umbilicus. We describe technique of totally transumbilical endoscopic cholecystectomy using improved instruments. METHODS: New trocars (5 and 3 mm in diameter, respectively) without proximal seal system on the sleeves were designed for this procedure. The maximum diameters of the trocars were reduced to 8 and 5 mm, respectively. The instruments used in this study were 5 cm longer than commercially available instruments. Ten cases of totally transumbilical cholecystectomy were performed successfully. RESULTS: All the gallbladders were removed successfully without severe bleeding during dissection, except one case of gallbladder wall perforation by cautery. Mean operating time was 62 +/- 25 min (range 45-110 min). All patients were satisfied with abdominal cosmetic results, discharged 48 h after the operation, and returned to work within seven postoperative days. CONCLUSIONS: External interference between trocars and instruments can be partially avoided by using the improved instruments. Totally transumbilical endoscopic cholecystectomy becomes feasible with this technique.
