Two case reports and literature review for hepatic epithelioid angiomyolipoma: Pitfall of misdiagnosis

引用

World Journal of Clinical Cases 2019年第8期7卷 972-983页

作者： Jia-Xi Mao Fei Teng Cong Liu Hang Yuan Ke-Yan Sun You Zou Jia-Yong Dong Jun-Song Ji Jun-Feng Dong Hong Fu Guo-Shan Ding Wen-Yuan Guo department of liver surgery and organ transplantation Changzheng Hospital Naval Medical University

BACKGROUND Hepatic epithelioid angiomyolipoma(HEAML) is a rare liver disease and is easily misdiagnosed. Enhanced recognition of HEAML is beneficial to the differential diagnosis of rare liver *** SUMMARY We presented two cases of HEAML in Changzheng Hospital, Naval Medical University, and then collected and analyzed all reports about HEAML recorded in PubMed, MEDLINE, China Science Periodical Database, and VIP database from January 2000 to March 2018. A total of 409 cases of HEAML in 97 reports were collected, with a ratio of men to women of 1:4.84 and an age range from 12 years to 80 years(median 44 years). Among the patients with clinical symptoms mentioned, 61.93%(205/331) were asymptomatic, 34.74%(115/331) showed upper or right upper quadrant abdomen discomfort, while a few of them showed abdominal mass, gastrointestinal symptoms, low fever, or weight loss. The misdiagnosis rate of HEAML was as high as 40.34%(165/409) due to its nonspecific imaging findings. Most of the tumors were solitary and round in morphology, with clear boundaries. Ultrasound scan indicated low echo with internal nonuniformity and rich blood supply in most cases. Computer tomography/magnetic resonance imaging enhanced scan showed varied characteristics. The ratio of fast wash-in and fast wash-out, fast wash-in and slow wash-out, and delayed enhancement was roughly 4:5:1. A definite diagnosis of HEAML depended on the pathological findings of the epithelioid cells in lesions and the expression of human melanoma black 45, smooth muscle actin,melanoma antigen, and actin by immunohistochemical staining. HEAML had a relatively low malignant rate of 3.91%. However, surgical resection was the main treatment for HEAML, due to the difficulty diagnosing before *** HEAML is a rare and easily misdiagnosed disease, and it should be diagnosed carefully, taking into account clinical course, imaging, pathological,and immunohistochemical findings.

Risk factors associated with early and late HAT after adult liver transplantation

引用

World Journal of Gastroenterology 2014年第30期20卷 10545-10552页

作者： Yi Yang Ji-Chun Zhao Lu-Nan Yan Yu-Kui Ma Bin Huang Ding Yuan Bo Li Tian-Fu Wen Wen-Tao Wang Ming-Qing Xu Jia-Yin Yang department of Vascular surgery Liver Transplantation CenterWest China HospitalSichuan University liver transplantation center Department of Liver SurgeryWest China HospitalSichuan University

AIM: To identify risk factors that might contribute to hepatic artery thrombosis (HAT) after liver transplantation (LT). METHODS: The perioperative and follow-up data of a total of 744 liver transplants, performed from February 1999 to July 2010, were retrospectively reviewed. HAT developed in 20 patients (2.7%). HAT was classified as early (occurring in fewer than 30 d post LT) or late (occurring more than 30 d post LT). Early HAT devel-oped in 14 patients (1.9%). Late HAT developed in 6 patients (0.8%). Risk factors associated with HAT were analysed using the chi(2) test for univariate analysis and logistic regression for multivariate analysis. RESULTS: Lack of ABO compatibility, recipient/donor weight ratio >= 1.15, complex arterial reconstruction, duration time of hepatic artery anastomosis > 80 min, duration time of operation > 10 h, dual grafts, number of units of blood received intraoperatively >= 7, number of units of fresh frozen plasma (FFP) received intraoperatively >= 6, postoperative blood transfusion and postoperative FFP use were significantly associated with early HAT in the univariate analysis (P = 1.15 (OR = 4.499), duration of hepatic artery anastomosis > 80 min (OR = 5.429), number of units of blood received intraoperatively >= 7 (OR = 4.059) and postoperative blood transfusion (OR = 6.898). Graft type (whole/living-donor/split), duration of operation > 10 h, retransplantation, rejection reaction, recipients with diabetes preoperatively and recipients with a high level of blood glucose or diabetes postoperatively were significantly associated with late HAT in the univariate analysis (P 10 h (OR = 6.394), retransplantation (OR = 21.793) and rejection reactions (OR = 16.936). CONCLUSION: Early detection of these

Mesohepatectomy versus extended hemihepatectomy for centrally located hepatocellular carcinoma

引用

Hepatobiliary & Pancreatic Diseases International 2014年第3期13卷 264-270页

作者： Xi Chen Bo Li Wei He Yong-Gang Wei Zheng-Gui Du Li Jiang department of liver surgery and liver transplantation center West China Hospital Sichuan University

BACKGROUND: Extended hemihepatectomy is usually recommended to treat large centrally located hepatocellular carcinoma (HCC). However, the morbidity and mortality are high because of the postoperative liver failure. Mesohepatectomy is seldom used because of its technical complexity This study aimed to evaluate the short-term and long-term curative effect of mesohepatectomy. METHODS: From January 2002 to September 2008, a total of 198 consecutive patients with centrally located HCC underwent hepatectomy in our department. According to the surgical procedures, they were divided into mesohepatectomy (group M, n=118), extended right hemihepatectomy (group RE, n=47) and extended left hemihepatectomy (group LE, n=33) groups. The surgical techniques, clinical pathological characteristics and outcomes were compared between group M, group RE and group LE. RESULTS: The operative time of group M was significantly longer than that of the other two groups (P0.05). The morbidity rate in group M was significantly lower than that in group RE (37.3% vs 55.3%, P=0.034), but not in group LE (37.3% vs 24.2%, P=0.163). The biliary leakage tended to be more common in group M (10.2%, P>0.05). The incidence of postoperative liver failure in group M was significantly lower than that in group RE (1.7% vs 10.6%, P=0.032), but not in group LE (1.7% vs 6.1%, P=0.208). The 1-, 3- and 5-year tumor-free survival rates and the overall survival rates after mesohepatectomy were 53.4%, 30.5% and 16.9% and 67.8%, 45.5% and 28.9%, respectively. CONCLUSIONS: Mesohepatectomy is a safe and effective technique for centrally located HCC patients. Compared with extende

Anterior vs conventional approach hepatectomy for large liver cancer:A meta-analysis

引用

World Journal of Gastroenterology 2014年第45期20卷 17235-17243页

作者： Lei Li Hai-Qing Wang Qing Wang Jian Yang Jia-Yin Yang department of liver surgery Liver Transplantation Center West China Hospital of Sichuan University

AIM: To evaluate the clinical outcomes and safety of anterior-and conventional-approach hepatectomy for patients with large liver tumors. METHODS: PubMed, EMBASE, Google Scholar and the Cochrane Library databases were searched for randomized controlled trials (RCTs) and controlled clinical trials comparing anterior-approach hepatectomy (AAH) and conventional-approach hepatectomy (CAH). Two observers independently extracted the data using a spreadsheet and assessed the studies for inclusion. Studies that fulfilled the inclusion criteria and addressed the clinical questions of this analysis were further assessed using either fixed effects or random effects models. RESULTS: Two RCTs and six controlled clinical trials involving 807 patients met the predefined inclusion criteria. A total of 363 patients underwent AAH and 444 underwent CAH. Meta-analysis indicated that the AAH group had fewer requirements for transfusion (OR = 0.37, 95%CI: 0.21-0.63), less recurrence (OR = 0.57, 95%CI: 0.37-0.87), and lower mortality (OR = 0.29, 95%CI: 0.13-0.63). There were no significant differences between AAH and CAH with regard to perioperative complications (OR = 0.94, 95%CI: 0.58-1.51), intraoperative tumor rupture (OR = 0.98, 95%CI: 0.40-2.40), or length of hospital stay (weighted mean difference = -0.17, 95%CI: -2.36-2.02). CONCLUSION: AAH has advantages of decreased transfusion, mortality and recurrence compared to CAH. It is a safe and effective method for large cancers requiring right hepatectomy.
