Study Completion Date: April 2012
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Laparoscopy
Laparoscopic cholecystectomy
Procedure: Cholecystectomy
Extirpation of the gallbladder by a surgical procedure
Experimental: Transumbilical
Transumbilical endoscopic cholecystectomy
Procedure: Cholecystectomy
Extirpation of the gallbladder by a surgical procedure
Experimental: Transvaginal
Transvaginal endoscopic cholecystectomy
Procedure: Transvaginal hybrid NOTES cholecystectomy
Cholecystectomy performed by using a combination of working tools inserted through the entry port for the minilaparoscopy and the videogastroscope, inserted into peritoneal cavity by transvaginal approach. The gallbladder is removed transvaginally through the videogastroscope.
Other Names:
  • NOTES cholecystectomy
  • Transvaginal cholecystectomy
Procedure: Cholecystectomy
Extirpation of the gallbladder by a surgical procedure

Detailed Description:

Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. At the present time these procedures are hybrids. It is expected a better cosmetic result and lower incidence in parietal complications in front of laparoscopic cholecystectomy, but is necessary to investigate that these benefits should not be associated with complications of the new access to abdominal cavity.

Methods. Prospective randomized clinical series of 60 female patients with gallstones that underwent endoscopic surgery, 20 of them operated with conventional laparoscopic approach, 20 by transumbilical endoscopic approach and 20 of them by transvaginal endoscopic approach. Variables as surgical wound infection, urinary tract infection, evisceration, hernia, mortality and other complications will be analyzed.
