Abstract:
Objective To explore the application of the “cross-shaped coordinate line localization method” in laparoscopic cholecystectomy (LC) to realize critical view of safety (CVS) as well as summarize its safety and practicality. Methods Eighty-four patients who were treated with the “cross-shaped coordinate line localization method” at the Department of General Surgery of Wuxi Branch of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from February 2020 to February 2023 were selected as the observation group, and 84 patients who were randomly selected to receive the traditional LC treatment during the same period were selected as the control group. In the observation group, the “cross-shaped coordinate line localization method” was used as the boundary mark to reach CVS, and complete cholecystectomy. In the control group, the traditional blunt and sharp operation methods were used to free gallbladder triangle, and dissect out the cystic ducts and cystic arteries one by one and ligate them off. The intraoperative, postoperative and related complications of the two groups were compared and analyzed. Results All 168 patients successfully completed LC without serious surgical complications or conversion to open cases. The observation group took longer operation time to than the control group [(89.5±12.3) min vs. (67.7±8.9) min, P<0.001), and intraoperative blood loss was less than the control group [(7.0±3.9) mL vs. (15.2±4.6) mL, P<0.001). The rate of biliary and vascular anomalies in the observation group was higher than that in the control group (9.5% vs. 1.2%, P=0.040). The observation group had higher mobility on the first postoperative day than the control group, and time to first postoperative feeding and time to first postoperative flatus were earlier than those of the control group (P<0.05). The overall incidence rate of related complications in the observation group was lower than that in the control group (2.4% vs. 10.7%, P=0.029). There was no statistically significant difference between the two groups in terms of drain placement and length of hospital stay (P>0.05). Conclusions The “cross-shaped coordinate line localization method”, with its constant anatomical position as the basic symbol, can help surgeons quickly lock the safe operation area and realize CVS of the gallbladder triangle to avoid bile duct injury and reduce the incidence of related complications.
