AIM: Gallbladder polyps are frequently discovered in recent year. If polyps are benign, and the gallbladder has a good function, it is not an absolute indication for cholecystectomy. For this reason percutaneous cholecystoscopic polypectomy of the gallbladder polyps were developed and applied.
METHODS: 100 patients with gallbladder polyps who were to undergo percutaneous endoscopic polypectomy of the gallbladder were studied. Under the epidural or general anesthesia, a mini laparotomy (2.5 to 3.0 cm) was performed subcostly in the right upper quadrant and the gallbladder fundus was then pulled out of the abdominal cavity with a grasping forceps. A rigid or flexible cholecystoscope was introduced into the gallbladder. The polyp stalk or basement mucosa of the polyps was coagulated by self-made microwave coagulator and then removed for histopathological evaluation. The preserved gallbladder was followed up to evaluate the efficacy of this innovative technique.
RESULTS: All procedures were uneventful with a mean operation time of 1h. 87 patients were followed-up for a mean of 5.5-year (1 to 11 years). The results showed that 74 patients were symptom free and their gallbladder function was found to be well preserved without recurrence of polyps and occurrence of gallstones on ultrasonography. The other 13 had mild upper abdominal discomfort and 3 of them their gallbladder function was proved insufficient with gallstone formation, the gallbladders were removed laparoscopically.
CONCLUSION: The procedure reported is a reliable, simple, applicable and minimally invasive technique to remove gallbladder polyps and to preserve gallbladder function for the patients who have benign gallbladder polyps. This technique need to be multicentral clinical trial.
