Clinical Study of Gimmi Ultramicro Instrument in Laparoscopic Cholecystectomy

To explore the practicability, feasibility and wound aesthetics of Gimmi ultra micro instrument in laparoscopic cholecystectomy. To retrospective analysis the clinical data of 75 patients undergoing elective surgery for gallbladder stones with chronic cholecystitis, gallbladder polyps and chronic cholecystitis who were admitted to the Department of General Surgery, Taikang Xianlin Drum Tower Hospital, Nanjing University School of Medicine, from October 2019 to October 2020. Among them, 35 cases used gimmi ultra micro instrument to remove the gallbladder (ultra-minimally invasive group) and 40 cases used the traditional three-hole method to remove the gallbladder (traditional group). The operation time, blood loss during operation, postoperative ventilation time, pain scores on the 1st and 3rd d after surgery, shortterm complications such as postoperative bleeding and bile leakage, incision scar satisfaction score, total hospital stay were compared between the two groups of patients and other indicators. Both groups of patients recovered and discharged without any bleeding or bile leakage after operation. The operation time of the ultra-minimally invasive group was slightly longer than that of the traditional group. There was no significant difference in the amount of blood loss, postoperative ventilation time and incision infection (p>0.05). The ultra-minimally invasive group was better than the traditional group in total hospital stay (p<0.05), on the 1st and 3rd d after operation, the ultra-minimally invasive group was better than the traditional group (p<0.05) and the ultra-minimally invasive group was significantly better than the traditional group (P<0.05). The gimmi ultra micro instrument is safe and reliable in laparoscopic cholecystectomy, the operation is not difficult, the postoperative pain of patients is low, the cosmetic effect is accurate and it is worthy of clinical application.
