Purpose: To determine the efficacy and efficiency of laparoscopic transverse abdominis plane block (Lap-TAP) in patients undergoing pancreatoduodenectomy and gastrectomy compared to those of ultrasound-guided TAP (US-TAP).
Methods: We retrospectively analyzed the records of patients who underwent open or minimally invasive (MIS) pancreatoduodenectomy and major gastrectomy with the use of Lap-TAP or US-TAP at our institution between November 1, 2018, and September 30, 2021. We compared the estimated time and cost associated with Lap-TAP and US-TAP. We also compared postoperative opioid use and pain scores between patients who underwent open laparotomy with these TAPs.
Results: A total of 194 patients were included. Overall, 114 patients (59%) underwent pancreatectomy, and 80 patients (41%) underwent gastrectomy. Additionally, 138 patients (71%) underwent an open procedure, and 56 patients (29%) underwent MIS. A total of 102 patients (53%) underwent US-TAP, and 92 (47%) underwent Lap-TAP. The median time to skin incision was significantly shorter in the Lap-TAP group (US-TAP, 59 min vs. Lap-TAP, 45 min; P < 0.001), resulting in an estimated reduction in operation cost by $602. Pain scores and postoperative opioid use were similar between Lap-TAP and US-TAP among open surgery patients, indicating equivalent pain control between Lap-TAP and US-TAP.
Conclusion: Lap-TAP was equally effective in pain control as US-TAP after pancreatectomy and gastrectomy, and Lap-TAP can reduce operation time and cost. Lap-TAP is considered the preferred approach for MIS pancreatectomy and gastrectomy, which occasionally needs conversion to laparotomy.
