Primary Outcome Measures:
- the incidence of surgical complications [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]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 ] [ Designated as safety issue: Yes ]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 ] [ Designated as safety issue: Yes ]Count patients' quality of life scores before sugery and at several time points after operation.
- pain scores [ Time Frame: up to 12 weeks ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]
- total cost of hospitalization [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 days ] [ Designated as safety issue: No ]
- Cosmetic results [ Time Frame: 1 month ] [ Designated as safety issue: No ]Through the incision length and patients' satisfaction to assess cosmetic results.
- The incidence of adverse events [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]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.

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.

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.

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 .
