AimThe enhanced recovery after surgery (ERAS) pathway and laparoscopic approach had been proven beneficial for patients and should now be considered as a standard of care in colorectal surgery. Multimodal analgesia is the gold standard in the ERAS program with the use of thoracic epidural analgesia (TEA). Few data are available on Transversus abdominis plane (TAP) blocks in laparoscopic colorectal surgery and ERAS pathway. The aim of this study is to evaluate the efficacy of TAP block compared to TEA in the management of postoperative pain and the impact on the recurrence of postoperative nausea, vomiting and ileus in laparoscopic colorectal surgery in the ERAS program.MethodFrom October 2014 to October 2016, 182 patients underwent elective colon surgical interventions in enhanced recovery after surgery pathway. The patients were divided into two groups: Group 1 (n = 92) and Group 2 (n = 91) who received TEA and TAP block, respectively, with a standardized postoperative analgesic regimen consisting of regular 1 g of paracetamol every 8 h and a rescue dose with intravenous non-steroidal anti-inflammatory drugs infusion for both groups.ResultsNo differences were observed in baseline patient characteristics, clinical variables and surgical procedures between the two groups, as well as in the postoperative complications rate (p = 0.515) in accordance with Clavien–Dindo classification, 90-day mortality (p = 0.319), hospital stay (p = 0.469) and 30-day readmission rate (p = 0.711). Patients in the TAP block group showed lower postoperative nausea and vomiting rates (p = 0.025), as well as lower ileus (p = 0.031) and paraesthesia rates (p = 0.024). No differences were found in urinary retention (p = 0.157). Despite the “opioid-free” analgesia protocol in the TAP block group, pain intensity was comparable between the two groups (p = 0.651).ConclusionTAP block combined with an opioid-sparing analgesia in the setting of the laparoscopic colorectal surgery and ERAS program is feasible and effective in postoperative pain control.
