Shoulder pain after natural orifice transluminal endoscopic surgery decreased with abdominal compression and pulmonary recruitment maneuver: A retrospective study

Objective: The study aimed to assess the efficacy of abdominal compression and pulmonary recruitment maneuver (CPRM) after transvaginal natural orifice transluminal endoscopic surgery (vNOTES) to alle-viate post-laparoscopic shoulder pain (PLSP). Materials and methods: In this retrospective cross-sectional study conducted in a tertiary referral medical center, women who underwent vNOTES between January 2018 and May 2019 were classified into control group and CPRM group with CO2 force expelled. Data on the demographic characteristics, indications for surgery, and surgical history were collected. Postoperative pain was assessed 24 and 48 h postoperatively using the visual analog scale (VAS, 0-10). Chest radiography was used to determine the residual air volume 24 h after surgery. Results: Of 10 patients, 6 and 4 underwent vNOTES adnexal surgeries and vNOTES hysterectomy, respectively. The median volumes of residual pneumoperitoneum were 9.02 mL and 28.11 mL in the CPRM and control groups, respectively (p = 0.001). The intensity of PLSP in the CPRM and control groups were 0 +/- 0 vs. 3.4 +/- 3.4 and 0.4 +/- 0.8 vs. 2.2 +/- 2.2 24 and 48 h after surgery, respectively (p = 0.005 for 24 h and p = 0.04 for 48 h). Conclusion: CPRM might facilitate decrease in residual gas volume and PLSP after vNOTES. CPRM might be considered using in vNOTES to decrease PLSP.

Automated summary

The study demonstrated that abdominal compression and pulmonary recruitment maneuver (CPRM) after transvaginal natural orifice transluminal endoscopic surgery (vNOTES) may help decrease residual gas volume and alleviate post-laparoscopic shoulder pain (PLSP).
