The purpose of this investigation is to compare the surgical conditions during laparoscopic cholecystectomy at a low intra-abdominal pressure with deep or moderate muscle relaxation.
The primary hypothesis is that surgical conditions during laparoscopic cholecystectomy are better with deep muscle relaxation than moderate muscle relaxation.

- The Percentage of Patients With Optimal Surgical Space Conditions ( 1 at a 4-step Scale) Assessed at the Time During Surgery, When View Was Less [ Time Frame: From surgical incision to last suture has been placed, an expected average of 30 minutes ]The surgical space conditions (4-stage scale) assessed at the time during surgery, when view was less. The laparoscopies were performed by experienced surgeons, whom were asked to evaluate surgical space conditions with a 4-point scale : Grade 1 ("optimal") = "optimal" surgical space conditions; Grade 2 (good) = non-optimal conditions, but an intervention was not considered; Grade 3 (acceptable) = an intervention was considered in order to improve surgical space; Grade 4 (poor) = inadequate conditions and an intervention was necessary in order to ensure acceptable surgical space.
- Surgical Space Conditions [ Time Frame: From surgical incision to last suture has been placed, an expected average of 30 minutes. ]The surgical space conditions (VAS 0-100) assessed at the time during surgery, when they were poorest
- Surgical Space Conditions [ Time Frame: From surgical incision to last suture has been placed, an expected average of 30 minutes. ]The average surgical space conditions (VAS 0-100 and 4-stage scale) during the procedure.
- Surgical Space Conditions [ Time Frame: During dissection of the gallbladder ]The surgical space conditions during dissection of the gallbladder (4-stage scale and VAS 0-100).
- Pain [ Time Frame: Preoperatively to 7 days after surgery ]Pain (shoulder, incision, deep abdominal and general) as the area under the curve from preoperatively to 7 days after surgery.
- Pain [ Time Frame: At arrival to the postanesthesia care department, 2 hours and 1 day after surgery ]Pain (shoulder, incision, deeop abdominal and general) at arrival to the postanesthesia care department, 2 hours and 1 day after surgery.
- Normal Functional Level [ Time Frame: from the day of surgery to re-establishing normal functional level - an expected average of 7 days. ]Numer of days before re-establing normal functional level
- Surgical Procedures at Low Pneumoperitoneum [ Time Frame: From surgical incision to last suture has been placed, an expected average of 30 minutes. ]Number of procedures which can be done with pneumoperitoneum 8 mmHg
- Duration of Surgery [ Time Frame: From surgical incision to last suture has been placed. ]Duration of surgery
- Duration of Anesthesia [ Time Frame: From induction of anesthesia to patient ready to leave the operating theatre ]Duration of anesthesia
- Consumption of Analgesics [ Time Frame: The first 24 hours after surgery ]Consumption of analgesics during the first 24 hours after surgery
- Nausea and Vomiting [ Time Frame: The first 24 hours after surgery ]The incidence of nausea and vomiting during the first 24 hours after surgery
- Anti-emetics [ Time Frame: During the first 24 hours after surgery ]Use of anti-emetics during the first 24 hours after surgery
