Laparoscopic Anatomical Versus Non-anatomical hepatectomy in the Treatment of Hepatocellular Carcinoma: A randomised controlled trial.

BACKGROUND: The choice of surgical modality for laparoscopic hepatectomy for hepatocellular carcinoma (HCC) has not been supported by high level of medical evidence hitherto. A prospective randomised controlled trial (RCT) was conducted to compare the perioperative and follow-up outcomes of patients with HCC treated by laparoscopic anatomical hepatectomy (LAH) and non-anatomical hepatectomy (LNAH). METHODS: Between March 2013 and Jan 2018, eligible patients undergoing LAH and LNAH were enrolled and divided randomly into LAH group and LNAH group in this study. The perioperative and follow-up outcomes of both groups were compared and analysed. RESULTS: A total of 385 patients with HCC were randomly divided into LAH (n = 192) and LNAH (n = 193) groups. The groups were evenly matched for age, sex, liver background, segment involvement, tumor size, Child-Pugh grade and preoperative liver function. The operative time in the LAH group was longer than that of the LNAH group (p = 0.003). No significant between-group differences in intraoperative blood loss (p = 0.368), transfusion rate (p = 0.876), conversion to laparotomy rate (p = 0.365), overall complication rates (p = 0.054) were observed. The 1-year, 3-year and 5-year overall survival rates (OS) in the LAH group were 91.1%, 67.2%, 43.2%, respectively. The corresponding data in the LNAH group were 89.1%, 63.7%, and 35.2%, respectively. No significant difference was observed with regard to the 5-year OS rate (p = 0.054) between the two groups. The 1-year, 3-year and 5-year disease-free survival (DFS) rates in the LAH group were 87.0%, 54.7%, 33.9%, respectively. The corresponding data in LNAH group were 70.5%, 34.7%, and 30.1%, respectively. The 5-year DFS rate in the LAH group was significantly higher than that in the LNAH group (p = 0.009). CONCLUSIONS: LAH versus LNAH for selected HCC patients was associated with increased DFS, lower intrahepatic ipsilateral recurrence rate, comparable long-term OS and postoperative complications. LAH is therefore recommended for selected HCC patients. REGISTRATION NUMBER: NCT02009176 (https://www. CLINICALTRIALS: gov/).

[Percutaneous plate fixation of three and four-part proximal humerus fractures in elderly patients].

OBJECTIVE: To evaluate the treatment effect of three and four-part fractures of proximal humerus in elder patients using indirect reduction combined with locking proximal humeral plate (LPHP) fixation. METHODS: From November 2004 to May 2008, 24 cases of proximal humeral three and four-part fracture were treated with percutaneous plate fixation using LPHP included 6 males and 18 females with an average age of 70 years old ranging from 55 to 88 years. The surgery was performed through antrolateral transdeoltoid approach. After extra articular capsule indirect reduction, the plate was inserted through the incision, and then an incision was made distal to previous incision to expose distal plate. The proximal fragments were fixed with 4 to 6 screws, and distal fragments were fixed with 3 screws. Shoulder exercises were performed at the 2nd to 3rd day after operation. Two weeks after operation, active shoulder exercise was done, which was gradually intensified 3 weeks after operation. The functional outcomes of the shoulder were assessed according to Constant score. RESULTS: All the fractures united clinically and radiologically. The mean healing time was 10.5 weeks (8 to 21 weeks). The mean Constant score was 81.6 points (49 to 92 points). A total of 20 patients had excellent or satisfactory result, with only one scored as poor. CONCLUSION: The technique of extra articular capsule indirect reduction combined LPHP internal fixation has the advantages of stable, easy to operate, less vascular damage and so on. It can effectively treat the proximal humerus three-and four-part fractures, especially to elder patients.
