Postoperative Pain Results According to Pressure to Form Pneumoperitoneum

Laparoscopic cholecystectomy was the most common treatment method for gallbladder-related diseases, and robotic cholecystectomy was also currently being performed. Many patients complained pain around the wound, shoulder and back after surgery. Several methods had been attempted to reduce postoperative pain, previous studies showed that oral medications such as NSAIDS, administration of local anesthetics in wounds and abdominal cavity, low-pressure penumoperitoneum, humidification of intraperitoneal washing fluid, And active residual gas suction in the abdominal cavity had been found to relieve postoperative pain. Robotic cholecystectomy, similar to laparoscopic cholecystectomy, also formed pneumoperitoneum to secure the surgical space during operation. Based on the results published in various studies, it had known that the most effective method of pain relief for laparoscopic pain was to create low-pressure pneumoperitoneum. In this study, investigators attempted to prove the effectiveness of low pressure pneumoperioneum through a prospective randomized controlled trial between the experimental group with the low-pressure pneumoperitoneum and the control group with the standard-pressure pneumoperitoneum during robotic single-hole cholecystectomy.
