Evidence-based management of pain after laparoscopic cholecystectomy: a PROSPECT review update.

BACKGROUND

Significant pain can be experienced after laparoscopic cholecystectomy. This systematic review aims to formulate PROSPECT (PROcedure SPECific Postoperative Pain ManagemenT) recommendations to reduce postoperative pain after laparoscopic cholecystectomy.

METHODS

Randomised controlled trials published in the English language from January 2006 (date of last PROSPECT review) to December 2017, assessing analgesic, anaesthetic, or operative interventions for laparoscopic cholecystectomy in adults, and reporting pain scores, were retrieved from MEDLINE and Cochrane databases using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) search protocols. PROSPECT methodology was used, and recommendations were formulated after review and discussion by the PROSPECT group (an international group of leading pain specialists and surgeons).

RESULTS

Of 1988 randomised controlled trials identified, 258 met the inclusion criteria and were included in this review. The studies were of mixed methodological quality, and quantitative analysis was not performed because of heterogeneous study design and how outcomes were reported.

CONCLUSIONS

We recommend basic analgesic techniques: paracetamol + NSAID or cyclooxygenase-2 specific inhibitor + surgical site local anaesthetic infiltration. Paracetamol and NSAID should be started before or during operation with dexamethasone (GRADE A). Opioid should be reserved for rescue analgesia only (GRADE B). Gabapentanoids, intraperitoneal local anaesthetic, and transversus abdominis plane blocks are not recommended (GRADE D) unless basic analgesia is not possible. Surgically, we recommend low-pressure pneumoperitoneum, postprocedure saline lavage, and aspiration of pneumoperitoneum (GRADE A). Single-port incision techniques are not recommended to reduce pain (GRADE A).
