"Non-Scar" Total Laparoscopic Cholecystectomy through the Transumbilical Approach / 中国微创外科杂志

ABSTRACT

Objective To investigate the feasibility of "non-scar" total laparoscopic cholecystectomy trough the transumbilical approach by using modified instruments.Methods Trocars(5 and 3 mm in diameter respectively)without the 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.10 cases of total laparoscopic cholecystectomy were performed by using the tools.Results All the gallbladders were removed successfully without massive bleeding during dissection.A mini port was placed on the right upper abdomen to assist retraction in one case because of technical difficulty.The mean operation time was(62?25)minutes(range,45 to 110 minutes)in this series.No intra-and postoperative complications occurred.All the patients were satisfied with the abdominal cosmetic results.They were discharged in 48 hours after the operation,and then back to work in a week.Follow-up was available in the patients for 1 to 5 months.None of them showed complication or recurrence during the period.Conclusions The interference between trocars and surgical instruments can be partially avoided by using the modified tools."Non-scar" total laparoscopic cholecystectomy is feasible by using the technique.
