Attempts to remove the gallbladder by non-surgical means began in the 1980's, by applying chemicals, heat or laser to remove its mucosa and reduce it to an innocuous scar. The aim of this work is to determine whether complete ablation of this organ is possible using total ablation by applying a diode laser.Thirty rabbits were divided into 3 groups of 10 animals. The gallbladder was surgically accessed and a 980 nm diode laser was applied endoluminally using fibre optics until it shrunk. Ethanol was used as a sclerosing agent plus a fibrin tail to seal the gallbladder lumen in one of the control groups, and a physiological solution was used in the rest. The animals were slaughtered at 65 days and the results of the procedure were observed macroscopically and histologically, evaluating the remains of the gallbladder lumen, fibrosis, and areas of re-epithelialisation. Statistical analysis was made using the Fisher test.Eight of the gallbladders treated by laser disappeared leaving a small sub-hepatic scar. There were no complications during or after surgery. The results were successful in only case in the ethanol group, and there was no ablation with physiological solution. The comparison of the results showed a significant positive difference in the group treated with laser compared to those with ethanol plus fibrin tail (P.0055) and the physiological solution (P.0007).Ablation of the gallbladder using a diode laser was possible in this experimental model. |
