Clinical Trial Summary

This study showed the difference in postoperative pain between the groups that performed surgery with the low-pressure pneumoperitoneum and the group that performed surgery in the standard-pressure pneumoperitoneum when robotic single-hole cholecystectomy was performed.

The primary purpose of the study was to compare the differences in the visual analog scale (VAS) between the two groups and to demonstrate the effectiveness of pain relief after surgery.

Secondly, the effect of the low-pressure pneumoperitoneum on the patient's postoperative recovery and outcome was compared with the control group by comparing the length of stay, operation time, and postoperative complications.

Description:

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.

Intervention

Procedure:
• robotic single port cholecystectomy
Local anesthetic administration during wound incision In the experimental group and the control group, a local anesthetic was administered to the wound surface when a glove port was installed on the navel at the start of surgery. (bupivacaine 0.5% 14ml subcutaneous injection) Residual gas aspiration Pulmonary recruitment maneuver In both the experimental group and the control group, before the operation was completed and the wound was closed, the patient was taken to the Trenedelenburg position, and then the pressure of 60 cm H2o in the abdomen was applied, and manual inflation was performed twice, 5 seconds at a time, and pulmonary recruitment was performed. Warming of the washing solution in the abdominal cavity

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analogue Score(VAS)	The Visual Analogue Scale (VAS) consists of a straight line with the endpoints defining extreme limits such as 'no pain at all' and 'pain as bad as it could be'. The patient is asked to mark his pain level on the line between the two endpoints. The distance between 'no pain at all' and the mark then defines the subject's pain.	24 hours after surgery
Secondary	postoperative complication	postoperative complication : bile leakage, atelectasis, pneumonia, wound infection, bleeding, etc..	Participants will be followed for the duration of hospital stay, an expected average of 2 days
Secondary	hospital stay	hospital stay(days) : The duration between the operation day and the day of discharge	Participants will be followed for the duration of hospital stay, an expected average of 2 days
Secondary	operation time	operation time(minutes)	Participants will be followed for the duration of hospital stay, an expected average of 2 days
