Clinical and economic comparison of laparoscopic versus open hepatectomy for primary hepatolithiasis: a propensity score-matched cohort study.

BACKGROUND: It is unclear whether laparoscopic hepatectomy (LH) for hepatolithiasis confers better clinical benefit and lower hospital costs than open hepatectomy (OH). This study aim to evaluate the clinical and economic value of LH versus OH. METHODS: Patients undergoing OH or LH for primary hepatolithiasis at Yijishan Hospital of Wannan Medical College between 2015 and 2022 were divided into OH group and LH group. Propensity score matching (PSM) was used to balance the baseline data. Deviation-based cost modelling and weighted average median cost (WAMC) were used to assess and compare the economic value. RESULTS: A total of 853 patients were identified. After exclusions, 403 patients with primary hepatolithiasis underwent anatomical hepatectomy (OH n=143; LH n=260). PSM resulted in 2 groups of 100 patients each. Although LH required a longer median operation duration compared with OH (285.0 versus 240.0 min, respectively, P<0.001), LH patients had fewer wound infections, fewer pre-discharge overall complications (26 versus 43%, respectively, P=0.009), and shorter median postoperative hospital stays (8.0 versus 12.0 days, respectively, P<0.001). No differences were found in blood loss, major complications, stone clearance, and mortality between the two matched groups. However, the median overall hospital cost of LH was significantly higher than that of OH (CNY¥52,196.1 versus 45,349.5, respectively, P=0.007). Although LH patients had shorter median postoperative hospital stays and fewer complications than OH patients, the WAMC was still higher for the LH group than for the OH group with an increase of CNY¥9,755.2 per patient undergoing LH. CONCLUSION: The overall clinical benefit of LH for hepatolithiasis is comparable or even superior to that of OH, but with an economic disadvantage. There is a need to effectively reduce the hospital costs of LH and the gap between costs and diagnosis-related group reimbursement to promote its adoption.

Image classification of liver cancer surrounding right hepatic pedicle and its guide to precise liver resection.

PURPOSE: The aim of this study was to explore the feasibility of image classification of liver cancer surrounding right hepatic pedicle (RHP) and its guide to precise liver resection. METHODS: Twenty-five patients with single liver cancer surrounding RHP were collected. According to the adjacent relationship between neoplasm and RHP shown in CT or MRI, the liver neoplasms were divided into the 4 types, type A neoplasm infiltrating or surrounding RHP, type B neoplasm locating in the anterior side of RHP, type C neoplasm locating in the dorsal side of RHP and type D neoplasm locating between the two branches. On the basis of image classification, operation project including hepatic vascular occlusion (HVO) and surgical resection procedure was designed. In the end, preoperative classification and surgical design was compared with operative results. RESULTS: The locations of liver neoplasms were completely in line with preoperative classification. The methods of HVO and range of surgical resection were essentially coincident with preoperative plan. Pringle maneuver, total hepatic and hemihepatic vascular occlusion were applied. Four patients with type A neoplasms underwent right hemihepatectomy or extended right hepatectomy. Seven with type B received right anterior lobectomy or mesohepatectomy. Six with type C underwent segment V, VI resection, and eight with type D received right anterior or posterior lobectomy. All operations were smoothly finished. CONCLUSION: Preoperative classification guided by RHP can provide the accurate location information for liver cancer surrounding RHP, contribute to choosing suitable method of HVO and reasonable range of hepatic resection for precise surgery.

Outreach syphilis testing services by different health providers to female sex workers in southern China.

Health providers have played important roles on delivering prevention and care services to control syphilis in China. The current study was aimed to evaluate the performance of different health providers in providing outreach syphilis testing services to female sex workers (FSWs). The current study carried out during April to August 2009 in Liuzhou was aimed to investigate the services delivered by two different types of clinics in China. A total of 1,808 FSWs recruited from sex work venues were included in the study. Prevalence of positive syphilis test (6.4%) among FSWs accessed by the local center for disease control outreach teams (CDC teams) was significantly lower than that (9.3%) among FSWs accessed by the local reproductive health hospital outreach teams (RHH teams). As compared with CDC teams, RHH teams had more FSWs to be successfully referred to the designated STD clinics for further syphilis confirmation and intervention (85.7% vs. 26.7%, P<0.001). These findings indicate that RHH teams may be more efficient than CDC teams to provide outreach-based services to FSWs. Participation of the reproductive health providers or other medical facilities in outreach services to FSWs should be considered in developing intervention programs in China.
