laparoscopic transversus abdominis plane block
Brief summary
This trial is a prospective randomized superiority trial comparing sole ropivacaine based local trocar site infiltration to local infiltration combined with laparoscopic ropivacaine TAP block (STALL) in LCC. There are only a few randomized trials comparing sole local anesthesia to additional laparoscopic TAP block in laparoscopic cholecystectomy and they have yet failed to show evidence in favor of TAP block. We hypothesize STALL (Single Transversus Abdominis Laparoscopy-guided plane block combined with Local trocar site ropivacaine infiltration) is superior to local port site infiltration, provided that the sample size is sufficiently big. The aim of this randomized study is to compare the efficacy of sole local anesthesia of trocar sites to STALL in LCC.

Study design
Masking description
The study will be blinded to patients and recovery room personnel, as well as the ward nurses and physicians, but not to operating surgeon(s), anesthesiologist(s), and nurses, treating patients during the surgery.
Intervention model description
Patients are analyzed following the intention to treat in three subgroups: 1. Patients treated in day-care outpatient surgical unit (DS): TAP+local vs local. 2. Patients treated electively in the inpatient surgery unit (IS): TAP+local vs local. 3. Emergency surgery patients (ES): TAP+local vs local.
Eligibility
Inclusion criteria
* All patients scheduled for elective or emergency LCC, aged over 18 and able to give an informed consent.
Exclusion criteria
* Age under 18 years, chronic daily opioid and/or pain tolerance / pain threshold -modifying medication use (abuse), pregnancy, known allergy to local anesthetics, diagnosed severe coagulopathy and incapability to give informed consent for whatever reason.
