Periumbilical infiltration of lidocaine with epinephrine for postoperative pain reduction in single-port laparoscopic adnexal surgery

An efficient and simple approach to control postoperative pain in transumbilical single-port laparoscopic surgery appears necessary. We conducted a retrospective analysis in a study group (80 patients who received periumbilical infiltration of lidocaine with epinephrine before their incisional site repair completion) and control group (80 patients who received no analgesic at their incisional site repair completion) matched for their age, body mass index and their frequency of previous abdominal surgery. The pain scores based on the numerical rating scale (NRS) and the analgesic use frequency during the postoperative period were evaluated. The postoperative pain scores based on the NRS were significantly lower in the study group than in the control group immediately after the operation and at postoperative 6 hours. The postoperative analgesic use frequency during the hospital stay and the pain scores at 24 and 48 hours were not significantly different between the two groups. Periumbilical infiltration of lidocaine with epinephrine can reduce surgical pain until 6 hours, postoperatively. Impact statementWhat is already known on this subject? No consensus on whether single port laparoscopic surgery significantly reduces postoperative pain, as compared to conventional laparoscopy exists, and the immediate postoperative pain seems to be severe even with the SPL surgery. What do the results of this study add? The periumbilical infiltration of lidocaine with epinephrine can alleviate surgical pain until 6 hours, postoperatively. What are the implications of these findings for clinical practice and/or further research? Our result may provide an efficient and simple approach to control postoperative pain in a single port laparoscopic surgery.
