ABSTRACT
Objective:To evaluate fibrotic border guided anatomical hepatectomy in the treatment of hepatolithiasis complicated with atrophy-hypertrophy complex.Methods:One hundred and sixty-seven cases undergoing hepatectomy guided by the boundary of liver fibrosis in the treatment of hepatolithiasis complicated with atrophy-hypertrophy complex from Jan 2011 to Dec 2019 in Hunan Province Peopole's Hospital were reviewed.Results:All patients were successfully treated by anatomical hepatectomy under the guidance of the liver fibrosis boundary with intraoperative choledochoscopy,the operation time was (231.5±37.1) min and the average blood loss was (375.7±52.6) ml,the average hospital stay was (10.2±1.1) days,the residual stone rate was 8.9%, according to the scoring system of Clavien-Dindo, Grade Ⅰ complications occured in 86 cases, Grade Ⅱ complications occured in 35.Follow-up ranged from 3 to 107 months, 15 cases had recurrent stones,four were reoperated.Conclusions:Fibrotic border guided anatomical hepatectomy in the treatment of hepatolithiasis complicated with atrophy-hypertrophy complex is safe and effective.
ABSTRACT
Objective:To study the feasibility, safety and technique for laparoscopic anatomical liver resection of segment 8.Methods:The clinical data of 9 patients who underwent laparoscopic anatomical liver resection of segment 8 from January 2015 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. There were 6 males and 3 females, with age ranging from 29 to 67 years (average 53.6 years). The operation time, intraoperative blood loss , postoperative hospital stay, postoperative complications, and long-term survival and recurrence rates on follow-up were analysed.Results:Laparoscopic anatomical liver resection of segment 8 was successfully carried out in these patients. The mean operative time was 188.9 min(range 140-240 min). The mean estimated intraoperative blood loss was 117.8 ml (range 20-300 ml). The postoperative hospital stay was 6.9 days (range 3-12 days). One patient developed pleural effusion after operation and responded to conservative treatment. Another patients developed ascites with delayed extubation. The patient was successfully treated with conservative treatment. No patients developed complications above Clavien Dindo Ⅲa. There were no perioperative deaths. The postoperative pathological results showed hepatocellular adenoma ( n=2), hepatocellular carcinoma ( n=4), cholangiocarcinoma ( n=1), and metastatic liver cancer ( n=2). On follow-up for 12-58 months (median 22 months) one patient with hepatocellular carcinoma developed recurrence at 18 months after operation and was treated with microwave ablation. The other patients were well on follow-up. Conclusions:With adequate preoperative evaluation, reasonable case selection, rigorous surgical planning, and skilled laparoscopic techniques, laparoscopic anatomical liver resection of segment 8 was safe and feasible, and the short-term efficacy was good in this study.
ABSTRACT
Objective:To evaluate short-term therapeutic effect of surgical treatment for complicated hepatolithiasis under the guidance of 3D reconstruction.Methods:We retrospectively analyzed the clinical data of 56 patients with complicated hepatolithiasis undergoing surgical treatment with the guidance of 3D reconstruction at the Department of Hepatobiliary Surgery of Hunan Province People′s Hospital from Jan 2011 to Jun 2019.Results:All the patients were successfully operated on under the guidance of three-dimensional reconstruction and extraction of residual stones by choledochoscope. The average duration of operation was 210.3 minutes and the average blood loss was 350.6 ml. According to the scoring system of Clavien-Dindo, Grade Ⅰ complications occurred in 36 cases, Grade Ⅱ complications in 5 cases and there were no complications of Grade Ⅲ or higher. As found by an average follow-up of 3.6 years (range from 5 months to 8 years) , only one patient had reflux cholangitis .Although the rate of residual stone was 68.8%, most stones remained only in the end branch of bile duct, hence do not interfere much with the patients′ living status.Conclusions:The surgical treatment with the guidance of 3D reconstruction is of satisfactory short-term curative effect in complicated hepatolithiasis.
ABSTRACT
Objective To improve the method for determination of geniposide in Fructus Gardeniae.Methods The improved method was compared with the pharmacopoeia method.The content of geniposide was determined by HPLC at 238nm detection wavelength with acetonitrile-water(15:85)as mobile phase .Results The improved method in which 50 % methanol was used as solvent was superior to the pharmacopoeia method in which methanol was adopted as solvent.A higher geniposide content was abtained from the former.Conclusion The improved method is convenient and accurate,and can be used to supply reference evidence for the assay of Fructus Gardeniae in the new edition of pharmacopoeia.
