A new exploration for gallbladder polyps: gallbladder polypectomy by endolap technique.
Abstract Gallbladder polyps are most commonly treated with cholecystectomy, which is associated with various complications. For benign disease, preserving the gallbladder is preferable. Since 1994, we have been exploring percutaneous polypectomy and have recently developed an improved new technique. This study reports a new endoscopic-laparoscopic (Endolap) technique for the removal of polyps and the preservation of the gallbladder. Nine Chinese mini-pigs were used to observe mucosal regeneration. Microwaves of 50-70 mA for 9 seconds were safe, and the gallbladder mucosa of pigs recovered to nearly normal 2 weeks later. In the clinical cases, 60 patients with gallbladder polyps were studied. With the patient under general anesthesia, each polyp stem was coagulated, and then the polyp was removed. All procedures were successful at between 60 and 135 minutes. The success rate was 93.33% (56/60). A retrospective analysis was conducted to assess the recovery of gallbladder function. All patients were followed up and symptom-free, without recurrence of the polyps; 3 months after the operation, the volume and contraction of the gallbladder recovered to preoperative levels. Thus the Endolap technique is reliable for removing benign gallbladder polyps and is applicable to a wider range of clinical situations than percutaneous polypectomy.
