Abstract:
Objective:To investigate the application value of triangular modal construed for planning approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients who underwent local laparoscopic resection of liver tumors located in superior part of central liver lobe at the Affiliated Hospital of Qingdao University from January to June 2020 were collected. There were 6 males and 4 females, aged from 41 to 63 years, with a median age of 54 years. Preoperative triangular model was constructed for all patients to plan approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe. Observation indicators: (1) preoperative general situations of patients; (2) surgical situations; (3) follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect tumor recurrence and survival of patients up to February 2021. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed was absolute numbers. Results:(1) Preoperative general situations of patients: hepatocellular carcinoma was found in 7 cases, inthahepatic cholangiocarcinoma was found in 2 cases and ovarian cancer with liver metastasis was found in 1 case. Three cases had tumors located in S4a segment, 2 cases had tumors located in ventral subsegment of S8 segment, 2 cases had tumors located in dorsal subsegment of S8 segment, and 3 cases had tumors across the ventral segment of S4a+S8. The diameter of tumors was (3.4±1.0)cm. (2) Surgical situation: all the 10 patients underwent R 0 resection successfully, with no intraoperative blood transfusion or conversion to open surgery. The operation time of 10 patients was (149±59)minutes, the volume of intraoperative blood loss was (294±163)mL, the minimum surgical margin of specimen was (1.1±0.2)cm. The alanine aminotransferase was (324±151)U/L on the postoperative first day, the aspartic aminotransferase was (401±113)U/L on the postoperative first day, and the duration of postoperative hospital stay was (9±4)days. No bile leakage, hemorr-hage, reoperation or other complications occurred in all patients. (3) Follow-up: 10 patients were followed up for 7?13 months, with a median follow-up time of 11 months. All patients had no margin recurrence or distant metastasis. Conclusion:It is safe and feasible to construct triangular modal for planning approach of local laparoscopic resection of liver tumors located in superior part of central liver lobe.
