Application value of different operation methods in the treatment of left hepatolithiasis in special position / 国际外科学杂志

ABSTRACT

Objective:To study the application value of different operation methods in the treatment of left hepatolithiasis in special position (the stone is located in the sagittal section of left portal vein and/or near the proximal end of left hepatic vein).Methods:From July 2015 to June 2018, 58 patients with left hepatolithiasis in special position in Department of General Surgery, the First People′s Hospital of Tianmen City of Hubei Province were analyzed retrospectively. According to the different operation methods, they were divided into two groups left liver excision under laparoscopy and gallbladder incision stone group (left liver excision group, n=28) and laparoscopic left-half liver excision and bile tube excision stone removal group (left half liver excision group, n=30). The operation time, intraoperative bleeding, postopera-tive hospital stay, postoperative biliary fistula, postoperative bleeding, postoperative stone residue and stone recurrence were compared between the two groups.The measurement data with normal distributions were represented as ( Mean± SD), and comparison between groups was done using the t test. The chi-square test and Fisher precision test were used for comparison between counting data. Results:All 58 patients underwent laparoscopic surgery. Left liver excision group surgery time, in-serum bleeding, number of days hospitalized after surgery, number of postoperative bile fistula cases, number of postoperative bleeding cases were (161.53±30.56) min, (203.45±26.69) mL, (9.26±3.3. 86) days, 1 case, 1 case, left half liver excision group (153.16±42.63) min, (198.79±30.82) mL, (9.59±4.01) days 1 case, 1 case, The difference between the two groups was not statistically significant ( P>0.05). The number of postoperative stone residues was more than that of the left liver and outer leaf excision group (4 cases) than that of the left half of the liver excision group (1 case), and the number of postoperative stone recurrence cases was more than that of the latter (1 case), all of which were statistically significant ( P<0.05). The number of stone residues and stone recurrences after left liver excision group was 4 and 5 cases respectively, and the left half liver excision nurses were 1 case and 1 case, respectively, and the difference between the two was statistically significant ( P<0.05). Conclusion:For the left hepatolithiasis in special position (the stone is located in the sagittal section of the left branch of the portal vein and (or near the proximal end of the left hepatic vein in imaging), the lower abdominal left hemihepatectomy + choledocholithotomy is a safer and more effective treatment.
