Modified Single Port Laparoscopic Cholecystectomy

ABSTRACT

PURPOSE: Currently, single port laparoscopic cholecystectomy (SLC) is gradually being expanded. However, its operative time and complications are reportedly variable according to the surgeon's expertise and experience. In order to overcome these problems, we introduced surgical methods using a 2 mm sized auxiliary device (NELIS, Korea) in cholecystectomy. METHODS: Between March 2010 and October 2010, laparoscopic cholecystectomy was performed in 53 patients for non-inflammatory gallbladder stones or gallbladder polyps based on the computed tomography findings. Fourteen of 53 consecutive patients underwent SLC and others underwent CLC. The patient's clinical characteristics and operative results were evaluated retrospectively. RESULTS: Comparison of clinical characteristics between SLC and CLC groups indicated that the SLC group included younger patients (p=0.008), however other characteristics (sex, mean body index, and previous abdominal operation history) were not significantly different. Operative outcomesparameters including the intensity of postoperative pain, rate of wound complication, and postoperative hospital stay did not differ significantly between the 2 groups. Operative time of the SLC group was longer than that of the CLC group (p=0.002). However, the operative time was decreased according to the increasing SLC cases. By 3 months, patients in the SLC group reported significantly better cosmesis (p=0.036). CONCLUSION: SLC with an auxiliary device (2 mm, Hold port, NELIS) is technically feasible and might be an alternative method for obtaining a critical view of safety and cosmetic results.
