ARTICLE HIGHLIGHTS
Research background

Postoperative pain management for peroral endoscopic myotomy (POEM) is often neglected by anesthesiologists because of the short operative time, short hospital stay and the minimally invasive nature of the procedure.

Research motivation

The authors conducted this retrospective study to examine the postoperative pain intensity of achalasia patients receiving the POEM procedure and to investigate possible risk factors for postoperative pain.

Research objectives

To achieve better postoperative pain management.

Research methods

We included patients with achalasia who underwent POEM at Zhongshan Hospital from December 2017 to March 2018. The postoperative visual analog scale, postoperative sleep quality, basic patient information, and surgical parameters were collected.

Research results

The preoperative Eckardt score [odds ratio (OR): 1.82, 95% confidence interval (CI): 1.17-2.84, P < 0.001], previous treatment (OR: 7.59, 95%CI: 1.12-51.23, P = 0.037) and the distance between the end of the muscle incision and the cardia (OR: 1.52, 95%CI: 0.79-293.93, P = 0.072) were risk factors for post-POEM pain.

Research conclusions

Achalasia patients who underwent POEM experienced serious postoperative pain, which may affect sleep quality. A higher Eckardt score, previous treatment, and a longer distance between the muscle incision ending and the cardia were risk factors for poor post-POEM pain control.

Research perspectives

We will further explore the optimal approach to postoperative analgesia in patients who underwent POEM surgery in the randomized controlled trial study and will cooperate with endoscopists to explore the effect of the POEM modus operandi (intrapleural tunnel length and myotomy position) on postoperative pain.
