Less pain after transvaginal/transumbilical cholecystectomy than after the classical laparoscopic technique: short-term results of a matched-cohort study

Background Natural orifice surgery (NOS) is gaining acceptance as an alternative to the traditional laparoscopic technique, especially for cholecystectomy through the transvaginal route. However, NOS remains controversial concerning expected advantages in terms of short- and long-term outcomes and potential side effects. This study was designed to compare short-term outcomes between transvaginal/transumbilical and classical laparoscopic cholecystectomy (LC).
