Summary

Shoulder pain after laparoscopic cholecystectomy is not caused by residual CO2. Excessive traction on the triangular ligament and diaphragmatic stretching during insufflation are the primary culprits, impacting patient recovery.

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery
  • Pain Management

Background:

  • Post-laparoscopic cholecystectomy shoulder pain is a common complication.
  • The exact mechanism of this referred pain remains debated.
  • Understanding the cause is crucial for effective pain management strategies.

Purpose of the Study:

  • To investigate the mechanism of shoulder pain following laparoscopic cholecystectomy (LC).
  • To differentiate between residual CO2 and insufflation-related factors as causes of post-LC shoulder pain.

Main Methods:

  • Ninety patients undergoing LC were randomized into three groups: no intervention, CO2 absorption, or O2 insufflation with CO2 absorption.
  • Pre- and post-procedure partial pressures of oxygen (PO2) and carbon dioxide (PCO2) were measured.

  • Postoperative shoulder pain incidence and severity were assessed.

    • Main Results:

    • Group C (O2 insufflation) showed a significant PO2 difference compared to groups A and B.
    • Shoulder pain occurred in 43.33% of group A, 26.67% of group B, and 70% of group C.
    • Pain levels were significantly higher in group C compared to groups A and B.

    Conclusions:

    • Residual CO2 pneumoperitoneum is unlikely to be the primary cause of shoulder pain.
    • Excessive traction on the triangular ligament and diaphragmatic over-stretching during insufflation are identified as the main contributors to post-LC shoulder pain.
