  Purpose
The purpose of this study is to scientifically evaluate the safety, efficacy and cosmetic results of transumbilical laparoendoscopic single site cholecystectomy.

Condition Intervention Phase
Gallstone Gallbladder Polyps Procedure: CLC Procedure: TU-LESSC Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomized Controlled Trial Of Transumbilical Laparoendoscopic Single Site Cholecystectomy Versus Conventional Laparoscopic Cholecystectomy

Further study details as provided by Beijing Friendship Hospital:

Primary Outcome Measures:
  • the incidence of surgical complications [ Time Frame: up to 12 weeks ]
    The primary outcome messures are the incidence of surgical complications caused by the two surgeries.Bleeding,bile duct injury and bile leakage during operation.Wound infection,umbilical hernia,poke holes hernia and biliary fistula after operation.


Secondary Outcome Measures:
  • transfer rate [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 days ]
    TU-LESSC(transumbilical laparoendoscopic single site cholecystectomy)is converted to LC(laparoscopic cholecystectomy)or open sugery;LC is converted to open sugery.

  • quality of life scores [ Time Frame: up to 12 weeks ]
    Count patients' quality of life scores before sugery and at several time points after operation.

  • pain scores [ Time Frame: up to 12 weeks ]
    Use VAS(Visual Analogue Score)to count patients' pain scores at several time points after operation.

  • length of hospital stay [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 days ]
  • total cost of hospitalization [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 days ]
  • Cosmetic results [ Time Frame: 1 month ]
    Through the incision length and patients' satisfaction to assess cosmetic results.

  • The incidence of adverse events [ Time Frame: up to 12 weeks ]
    The adverse events occurred after surgery,regardless of whether they are caused by the tow operations。 Such as nausea, dizziness, urinary retention, vomiting and so on.

Arms Assigned Interventions
Active Comparator: Laparoscopic Cholecystectomy
Laparoscopic cholecystectomy(4 ports or 3 ports)will be performed in a routine fashion by one full time faculty member with fellowship training in laparoscopy.
Procedure: CLC
CLC(4 ports or 3 ports)will be performed in a routine fashion by one full time faculty member with fellowship training in laparoscopy.
Other Name: conventional laparoscopic cholecystectomy
Active Comparator: TU-LESSC
TU-LESSC will be performed in a routine fashion which is same to CLC(conventional laparoscopic cholecystetomy)by one full time faculty member with fellowship training in laparoscopy through the conventional laparoscopic instruments.
Procedure: TU-LESSC
TU-LESSC will be performed in a routine fashion which is same to CLC by one full time faculty member with fellowship training in laparoscopy through the conventional laparoscopic instruments.
Other Name: Transumbilical laparoendoscopic single site cholecystectomy

Detailed Description:
As the natural orifice during embryonic, the transumbilical surgery not only can mask the abdominal scar and avoid infection produced by puncturing stomach, vagina or rectum in NOTES,but also can be played by the conventional laparoscopic instruments. TU-LESS (transumbilical laparoendoscopic single site surgery), is considered to be the most feasible NOTES(natural orifice transluminal endoscopic surgery)technology at present. Researches about TU-LESS mostly are case reports and small samples or the control experiments up to now,there are not persuasive randomized controlled trail between TU-LESS and conventional laparoscopic cholecystectomy. So the investigators design this prospective randomized controlled trail to scientifically evaluate the safety, efficacy and cosmetic results of transumbilical laparoendoscopic single site cholecystectomy .
