Enhanced Recovery After Surgery

The effectiveness of transversus abdominis plane block (TAP) on pain management after laparoscopic colorectal surgery (CRS) remains unclear since the only relevant meta-analysis on this topic did not separate laparoscopic CRS from open CRS. The aim of the study was to compare the analgesic efficacy and safety of TAP with non-TAP in patients undergoing laparoscopic CRS. Four databases were searched for randomized controlled trials (RCTs) on this topic using relevant keywords. Two authors independently completed evidence selection, data extraction, and critical appraisal. Available data were pooled in the random-effects model, and point estimates with 95% confidence interval (CI) were reported for postoperative pain at rest and on coughing, opioid consumption, length of hospital stay, and adverse events. A total of 14 RCTs (n = 1216) contributed to the present synthesis. Pooled result showed that patients in the TAP group had lower pain at rest than those in the non-TAP group at postoperative 2-h (mean difference [MD] = -1.42; P < 0.05), 4-h (MD = −0.97; P < 0.05), 12-h (MD = −0.75; P < 0.05), and 24-h (MD = −0.61; P < 0.05). Patients in the TAP group also had lower postoperative pain on coughing than those in the non-TAP group on the first day (MD = −1.02; P < 0.05). Moreover, TAP had lesser postoperative opioid consumption than non-TAP (standardized mean difference, −0.26; P < 0.05; I-square = 20%), and there were non-significant differences in hospital stay and adverse event between the two groups. Intraoperative TAP is a safe and feasible pain management for laparoscopic CRS, particularly it is recommended when patient-controlled analgesia is not delivered. Therefore, laparoscopic TAP block might be a favorable administered strategy.
