Overview
Brief Summary
The purpose of this study is to compare the efficacy and safety of laparoscopically inserted transversus abdominis plane block (LTAP) in comparison to local wound analgesia in laparoscopic surgery due to suspected or diagnosed peritoneal endometriosis.
Detailed Description
The LTAP-trial is a prospective randomized controlled double-blinded study comparing the efficacy and safety of LTAP with local wound analgesia in laparoscopic endometriosis surgery. Patients are randomized to receive LTAP with levobupivacain and wound infiltration with placebo or wound infiltration with levobupivacain and LTAP with placebo. The primary outcome is postoperative opioid consumption measured by Patient Controlled Analgesia -pump (PCA). Secondly, subjective postoperative pain up to 24 h postoperatively will be measured by Numeric Rating Scale (NRS). Additional outcome measures are factors related to recovery and length of stay in the hospital as well as a 6 month follow-up survey regarding pain and general wellbeing after surgery. A total of 46 patients will be randomized in a proportion of 1:1.

Outcomes
Primary Outcomes
Postoperative opioid consumption
Time Frame: 24 hours
Oxicodone consumption measured via PCA-pump in Morphine equivalents
Secondary Outcomes
- Pain at six months postoperatively; assessed by NRS (numeric rating scale), (questionnaires sent to the patients)(6 months postop)
- Postoperative pain assessed by NRS (numeric rating scale)(Recovery room immediately postoperatively; on ward 6, 12 and 24 hours postoperatively)
- Quality of life at six months postoperatively; assessed by EHP-30 (endometriosis-related health profile) (questionnaires sent to the patients)(6 months postop)
- Intra- or postoperative complications(Up to 6 months postop)
