Chinese Journal of Digestive Surgery 2015;14(1):25-28
The application of enhanced recovery after surgery (ERAS) in hepatectomy is safe and feasible.The related researches of the clinical strategies of ERAS involved in colonic surgery instead of management of basic diseases of liver,and the influence of portal hypertension and hepatitis B virus infection on the ERAS has not been emphasized.According to the clinical strategies of ERAS in colon surgery,the basic diseases and the characteristics of liver were focused,and the clinical strategies of ERAS in the era of precision liver surgery were proposed.Through concerted efforts of the multidisciplinary team and a joint of surgeons,nurses and patients,the establishment of multicentre clinical studies under guidance of evidence-based medicine (EBM) will show clearly a development direction of the clinical strategies of ERAS in the era of precision liver surgery.
2.Pathological study of uterine fibroids after transcatheter uterine artery embolization
Journal of Interventional Radiology 2006;0(08):-
Pathological changes of uterine fibroide after transcatheter uterine artery embolization(TUAE) has been proven with regular pathological change during the elapse time after TUAE resulting in fibrotic proliferation. Inflammation took place first, followed by coagulation necrosis and hyaline degeneration but incomplete in most cases and finally with proliferative fibrous tissue formation. These dynamic changes of pathology are basis for fibroid volume reduction and recurrences. The factors affecting the extent of fibroid necrosis included tumor size,position and elapse of duration after TUAE. Inflammation was found in normal uterine tissue after TUAE but no necrosis occurred. The finding of embolization agent in peripheral vessels of adnexa may suggest future possible damage of function in ovary and fallopian tube. (J Intervent Radiol, 2006, 15: 507-509)
3.Current status, questions and challenges of transcatheter uterine artery embolization for the treatment of uterine fibroids
Journal of Interventional Radiology 2006;0(08):-
Current status, questions and challenges of transcatheter uterine artery embolization(UAE)in the treatment of uterine fibroids were summarized and analysed. It has been proved that UAE presents a good effectiveness in controlling the symptoms and shrinkage of fibroid and uterine volumes during follow-up of 4 to 6.9 years domestically and abroad, but relapse of the fibroid may however occur in 2 years or longer after UAE. Generally speaking,UAE is safe in the treatment of uterine fibroids but has a possibility of serious complications. UAE has no damage on normal uterine tissues but may affect pregnancy and delivery of patients significantly later on the cause of hypoxia and inertia of uterus. UAE may cause amenorrhea in the minority of women with ovarian failure and endometrium atrophy. The current questions are how to improve long-term efficiency to reduce relapse of tumor and to insure the safety of UAE. It is our further task to exploit more new effective and safe embolic agents by using animal and clinical study on the basic knowledge of pathology, pharmacology, biochemistry, endocrinology and molecular biology.

Uterine artery embolization(UAE)is a safe and effective method for uterine leiomyomas but its long and middle term effects are definite. Furthermore it bears some exguisite comparision with the conventional therapy but not as a radical one, with a tendency. However, to develop new leiomyomas and recurrence after UAE, there for all patients should be monitored with clinical and imaging examinations for more than 2 years after the procedure. At present,a few literatures involving the factors that could influence the effects of UAE have been issued. It is necessary to carry on large-scale clinical research of the related factors influencing the results of UAE in order to guide clinical practice correctly and swiftly.(J Intervent Radiol, 2006, 15: 503-506)

Thirty-seven patients with primary osteosarcoma treated with local radiation and arterial perfusion of cytotoxic agents followed by systemic chemotherapy from April 1986 to April 1992. Several patients themselves stopped the treatment. All patients were divided into 3 groups: Group A (18 cases) were treated by local radiation and arterial perfusion of DDP, followed by systemic chemotherapy; Group B (14 cases) were treated by local radiation and arterial perfusion with no or insufficient dose of systemic chemotherapy; Group C (5 cases) were treated by local radiation and arterial perfusion with insufficient half dose and no systemic chemotherapy. Except the patients in group C, all other patients(32 cases) were followed-up from 24 to 95 months. Local control rate of the tumors was 93.8%, hypokinesis rate of the limps decreased from 93.8% to 40.6%, and mean survival time with no evidence of cancer was 38 months after treatment . survival rates of 2,3,5 and 7 years in group A were 94.4%,92.3%,72.7% and 50%,respectively.The mean survival time from lung metastasis to death in 19 patients was 13.6 months. Our date showed that long term survival of group A was superior to other groups (P

Objective To investigate the pathologic basis of intrahepatic biloma formed in the patients with hepatocellulr carcinoma (HCC) after interventional treatment and to assess its clinical significance. Methods Three hundreds and fifty cases of HCC were followed up with CT examination after TAE/PEI, 11 cases received percutaneous bilomography, 10 cases received percutaneous biopsy, and 1 case had surgical resection. All cases of biloma underwent external drainage of bile or ethanol ablation. Results 11 cases of biloma were found (11/350), and all of them displayed a cystic dilation (11/11), 4 cases showed a columnar dilation with indefinite border (4/11), and 3 cases accompanied with a “soft rattan sign” of intrahepatic bile ducts (3/11). The pathologic findings included necrosis on the wall of the biliary tract, extravasation of bile, and infiltration with inflammatory cells. After the external drainage or the ethanol ablation, jaundice had been decreased and symptoms relieved (9/11). Conclusions Biloma is one of the complications of the patients with HCC after TAE/PEI caused by the necrosis of the wall of biliary tract, the correct diagnosis depends on the imaging procedures and biopsy. It is helpful to the further treatment to distinguish biloma from residual nidus of carcinoma. External drainage, stent placement, and ethanol ablation may be the choice of management.
