The Effect of Transvaginal vs. Conventional Laparoscopic Cholecystectomy on the Postoperative Course (TRAVAKOL)
|ClinicalTrials.gov Identifier: NCT01552421|
Recruitment Status : Terminated (For logistic reasons in the department and due to very low inclusion rates.)

Uncomplicated laparoscopic cholecystectomy will in most patients result in moderate to severe pain until the first postoperative day. This will subside during the second and third postoperative day . A feeling of low general well-being will also be present until the first postoperative day and subside during the next couple of days .
To achieve faster recovery after laparoscopic interventions it has been shown that a reduction in the size of laparoscopic ports and thereby incisions can reduce postoperative pain [3,4].
A new minimal invasive surgical technique is based on the principle of completely eliminating the use of ports through the abdominal wall. This new technique is called Natural Orifice Transluminal Endoscopic Surgery (NOTES) and is defined by acquiring minimal invasive access to the abdominal cavity through the body's natural openings like the mouth and stomach, anus, urethra and vagina. With the NOTES technique one can completely avoid incisions in the abdominal wall and thereby reduce the surgical trauma. The benefits of this technique is a reduction of postoperative pain, elimination of incisional hernias, prevention of wound infections, reduction of peritoneal adherence formation, achieving a faster recovery and a better cosmetic result [7,8].
The most documented and well-described way for gaining NOTES access to the abdominal cavity is through the vagina, transvaginal (TV). TV NOTES has mainly been used for cholecystectomy because of the direct line of vision to the upper abdomen and gallbladder that is achieved through this opening.
Compilation of results show that TV NOTES cholecystectomy can be implemented with low complication rates [20-22]. One retrospective case-control and one prospective observational study report less postoperative pain, reduced consumption of analgesics and faster recovery for TV NOTES compared to conventional laparoscopic cholecystectomy [23,24]. To date there are no systematic prospective randomized data on whether or not TV NOTES cholecystectomy leads to a better surgical outcome.
In the present study the postoperative course after TV NOTES cholecystectomy will be compared to laparoscopic cholecystectomy in a prospective randomized and blinded trial. The outcome of the randomization between the two surgical techniques will be blinded to patient and the nurse staff for the first 72 hours after the operation. The primary outcome parameter will be postoperative pain score during the first 24 hours. Secondary outcome parameters are postoperative pain score for the first 72 hours, fatigue, well-being, nausea, consumption of analgesics, complications, cosmetic result and sexual function.
The hypothesis being that TV NOTES cholecystectomy gives less postoperative pain, fatigue and nausea, a reduction in analgesics and a better cosmetic result and general well-being than conventional 4 port laparoscopic cholecystectomy.

Active Comparator: TV NOTES cholecystectomy
Participants randomized to TV NOTES cholecystectomy
Procedure: TV NOTES cholecystectomy
Transvaginal NOTES cholecystectomy
No Intervention: Laparoscopic cholecystectomy
Participants randomized to laparoscopic cholecystectomy
- Cumulated postoperative pain with visual analogue scale (VAS) [ Time Frame: 72 hours ]Postoperative pain will be measured with VAS, 3 hours after the operation as well as on the first, second and third postoperative day. Pain score will be assessed at rest and during mobilization from supine to erect posture. Based on these assesments a cumulated overall pain score for the first 72 postoperative hours will be calculated by adding the respective scores for each participant.
- Postoperative fatigue [ Time Frame: 72 hours ]Postoperative fatigue will be measured on a scale from 0 (no fatigue) to 10 (severe fatigue) 3 hours post surgery and on postoperative day 1, 2 and 3.
- Postoperative well-being [ Time Frame: 72 hours ]Well-being will be measured with VAS 3 hours post surgery and on postoperative day 1, 2 and 3.
- Postoperative nausea [ Time Frame: 72 hours ]Nausea will be measured with VRS 3 hours post surgery and on postoperative day 1, 2 and 3.
- Postoperative vomiting [ Time Frame: 72 hours ]Total number of times the participant have been vomiting 3 hours post surgery and on postoperative day 1, 2 and 3.
- Postoperative analgesic and antiemetic consumption [ Time Frame: 72 hours ]All participants will be given oral Paracetamol 1g four times a day and Ibuprofen 400 mg three times a day for the first 72 postoperative hours. Any need for additional analgesics besides this will be registered. Consumption of antiemetics will be registered.
- Postoperative complications [ Time Frame: 1 year ]Any postoperative complications will be registered during the participants admission and on follow-up 28 days (+/- 2 days) and 12 months (+/- 14 days) after surgery
- Cosmetic result [ Time Frame: 1 year ]Participants will be requested to score their satisfaction with the cosmetic result on a scale from 0 (no scarring) to 10 (severe scarring)28 days (+/- 2 days) and 12 months (+/- 14 days) after surgery.
- Sexual function and dyspareunia [ Time Frame: 1 year ]Participants are requested to fill in the questionnaire Female Sexual Function Index (FSFI) on sexual function and dyspareunia 28 days (+/- 2 days) and 12 months (+/- 14 days) after surgery.
- Postoperative hospitalization [ Time Frame: Until the individual participant is discharged from the hospital ]The time from admission to discharge from the hospital is recorded.
- Surgical details [ Time Frame: Intra-operative ]Details about the technical aspects of performing TV NOTES cholecystectomy is recorded during and immediate after surgery.
- Early postoperative pain with VAS [ Time Frame: 24 hours ]Early overall postoperative pain measured with VAS, 3 hours after the operation as well as on the first postoperative day. Pain score will be assessed at rest and during mobilization from supine to erect posture.
- Late postoperative pain measured with VRS [ Time Frame: 48 hours ]Late postoperative pain measured with VRS on the second and third postoperative day. Pain score will be assessed at rest and during mobilization from supine to erect posture.
- Early pain localization [ Time Frame: 24 hours ]Pain localization (abdominal wall, intra-abdominal or shoulder pain) will be measured with VRS, 3 hours postoperatively as well as on the first postoperative day.
- Late pain localization [ Time Frame: 48 hours ]Pain localization (abdominal wall, intra-abdominal or shoulder pain) will be measured with VRS, on the second and third postoperative day.
