ReviewThe effect of intraperitoneal local anesthesia in laparoscopic cholecystectomy: a systematic review and meta-analysis.
Intraperitoneal administration of local anesthesia is often used to improve pain relief after laparoscopic cholecystectomy. We have conducted a meta-analysis to establish the efficacy of this technique in reducing early postoperative abdominal pain. A systematic literature search revealed 24 randomized, controlled trials assessing intraperitoneal local anesthetic use in laparoscopic cholecystectomy that met inclusion criteria. ⋯ Subgroup analysis suggested that the effect was greater when the local anesthetic was given at the start of the operation (WMD, -13 mm; 95% CI, -19 to -7) compared with instillation at the end (WMD, -6 mm; 95% CI, -10 to -2). No adverse events related to local anesthetic toxicity were reported. We conclude that the use of intraperitoneal local anesthesia is safe, and it results in a statistically significant reduction in early postoperative abdominal pain.
