RESUMEN
Objective To observe the value of laparoscopic ultrasound(LUS)combined with CT three-dimensional reconstruction for guiding laparoscopic hepatectomy(LH).Methods Data of 78 hepatocellular carcinoma(HCC)patients who underwent LH were retrospectively analyzed.The patients were divided into observation group(n=46)or control group(n=32)based on whether underwent preoperative CT three-dimensional reconstruction and LUS.Clinical data,perioperative data and prognosis were compared between groups.Results No significant difference of clinical data was found(all P＞0.05),whereas significant differences of tumor body mainly location,resection method,tumor resection margin,surgical operation time,intraoperative blood loss,postoperative hospital stay,postoperative complication grading and incidence were found between groups(all P＜0.05).During follow-up period,15 patients died in observation group and 14 died in control group.Significant difference of disease-free survival rate was detected between groups(x2=4.210,P=0.040).Conclusion LUS combined with CT three-dimensional reconstruction for guiding LH could reduce intraoperative injury and complication incidence,improving disease-free survival rate of HCC patients.
RESUMEN
Objective:To study factors influencing postoperative pancreatic fistula rates with a view to prevent postoperation pancreatic fistula from happening.Methods:This is a retrospective study on 281 patients who underwent distal pancreatectomy at the First Affiliated Hospital of China Medical University from March 2011 to April 2018. There were 89 males and 192 females, with the age of (51.01±13.65) years. Univariate and multivariate logistic regression analyses were used to analyze the following factors on the occurrence of pancreatic fistula after operation: gender, age, body mass index(BMI), tumor characteristics, preoperative fasting blood glucose, blood biochemistry, liver function and surgical indications.Results:Of the 281 patients who underwent distal pancreatectomy in this study, 245 (87.2%) did not develop pancreatic fistula / biochemical leakage, while 36(12.8%) patients developed clinically significant pancreatic fistula (B/C grade). Univariate analysis showed the factors which affected the incidence of pancreatic fistula after surgery to include: BMI, preoperative fasting blood glucose, and whether the main pancreatic duct was ligated (all P<0.05). Multivariate logistic regression analysis showed that the independent factors affecting pancreatic fistula incidence after surgery were BMI≥25 kg/m 2 ( OR=2.354, 95% CI: 1.137-4.873, P<0.05), and main pancreatic duct was not ligated ( OR=4.067, 95% CI: 1.191-13.885, P<0.05). Conclusions:A high BMI increased the risk of postoperative pancreatic fistula, while ligation of main pancreatic duct during surgery reduced the risk.
