Abstract
BACKGROUND This study aimed to examine the inflow and outflow vascular system of the caudate lobe and determine its relevance to hepatobiliary surgery. METHODS A total of 41 cadaveric liver specimens were dissected in 2019 to evaluate the inflow and outflow vascular system of the caudate lobe. RESULTS The Glisson's pedicles of the paracaval portion were mainly from the right pedicle in 14 cases (34.15%), mainly from the left pedicle in 22 cases (53.66%), and equally from the left and right pedicle in 5 cases (12.19%). Many thick branches of the portal vein were found behind the plane consisting of the hilar plate and Arantius ligament, but none of them were thicker than 1 mm in front of the plane. All of the veins of the caudate lobe drained into the inferior vena cava (IVC) via the anterior face. There was an avascular zone without short hepatic veins (SHVs) consisting of loose connective tissue between the retrohepatic IVC and caudate lobe, with its length and width being 45-97 mm and 6-15 mm, respectively. CONCLUSIONS The plane consisting of the hilar plate and Arantius ligament can be regarded as the boundary between the caudate lobe and the other lobes. There is an avascular zone without SHVs consisting of loose connective tissue between the retrohepatic IVC and caudate lobe.

Abstract
The options of treatment for caudate tumors are presented. Treatment of caudate tumors by left-sided approach is proposal. Better results with left-sided approach are discussed. Selection of patients with tumors in caudate lobe for left-sided approach is important.
Introduction The caudate lobe is a distinct liver lobe and surgical resection requires expertise and precise anatomic knowledge. Left-sided approach was described for resection of small tumors originated in the Spiegel lobe but now the procedure has been performed even for tumors more than five centimeters. The aim of this study is to present three cases of tumor of caudate lobe underwent isolated lobectomy by left-sided approach. Presentation of case Three patients with metastasis of colorectal cancer, carcinoma hepatocellular and metastasis of neuroendocrine tumor underwent resection. After modified Makuuchi incision, early control of short hepatic e short portal veins before hepatectomy was performed. The operative time was 200, 270 and 230 min respectively. No blood transfusion was used and no postoperative complications were observed. The length of stay was 7, 11 and 5 days respectively. Discussion Some approaches have been described to access and resect tumors of the caudate lobe, including the left-sided approach, right-sided approach, combined left- and right-sided approach and the anterior transhepatic approach. For liver resection in patients with malignant disease, parenchymal preservation is important in order to avoid postoperative liver failure or due to the risk of second hepatectomy. In these patients isolated caudate lobectomy is a safe option. Conclusion Isolated caudate lobectomy is a feasible procedure. Left-sided approach can be preformed even for tumors larger than 5 cm.

Outcomes for primary kidney transplantation from donation after Citizens' death in China: a single center experience of 367 cases. BMC Health Serv Res 2017; 17:250. [PMID: 28376778 PMCID: PMC5379606 DOI: 10.1186/s12913-017-2190-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Accepted: 03/25/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The cases of donation after brain death followed by circulatory death (DBCD) and donation after cardiac death (DCD) have been increased year by year in China. Further research is needed to understand in the outcomes and risk factors of delayed graft function (DGF) in order to minimize the risk of DGF and ameliorate its potential impact on long-term outcomes. This study was to explore the differences in outcomes between DBCD and DCD transplant and the main risk factors for DGF in DBCD. METHODS Retrospective analysis of the clinical data of 367donations after citizens' death kidney transplant procedures (donors and recipients) between July 2012 and August 2015 at our center. RESULTS During the study period, the donation success rate was 25.3%. 164 cases of DBCD and 35 cases of DCD had been implemented and 367 kidneys were transplanted. The incidence of DGF in DBCD group were significantly lower than that of DCD group (12.0% vs. 27.0%, p = 0.002). The 1-year percent freedom from acute rejection (AR) was significantly higher in DBCD group compared with it of DCD group (94% vs. 82%, p = 0.036). Multivariate logistic regression analysis of the kidney transplants revealed that the high risk factors for DGF after renal transplantation in DBCD were history of hypertension (Odds Ratio [OR] = 5.88, 95% CI: 1.90 to 18.2, p = 0.002), low blood pressure (BP < 80 mmHg) (OR = 4.86, 95% CI: 1.58 to 14.9, p = 0.006) and serum creatinine of donor (OR = 1.09, 95% CI: 1.03 to 1.16, p = 0.003) before donation. CONCLUSIONS The outcomes of DBCD could be better than DCD in DGF and AR. The main risk factors for DGF in DBCD kidney transplants are donors with a history of hypertension, low blood pressure, and serum creatinine of donor before donation.

Hu HJ, Mao H, Shrestha A, Tan YQ, Ma WJ, Yang Q, Wang JK, Cheng NS, Li FY. Prognostic factors and long-term outcomes of hilar cholangiocarcinoma: A single-institution experience in China. World J Gastroenterol 2016; 22:2601-2610. [PMID: 26937148 PMCID: PMC4768206 DOI: 10.3748/wjg.v22.i8.2601] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Revised: 11/18/2015] [Accepted: 12/08/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the prognostic factors of hilar cholangiocarcinoma in a large series of patients in a single institution.
METHODS: Eight hundred and fourteen patients with a diagnosis of hilar cholangiocarcinoma that were evaluated and treated between 1990 and 2014, of which 381 patients underwent curative surgery, were included in this study. Potential factors associated with overall survival (OS) and disease-free survival (DFS) were evaluated by univariate and multivariate analyses.
RESULTS: Curative surgery provided the best long-term survival with a median OS of 26.3 mo. The median DFS was 18.1 mo. Multivariate analysis showed that patients with tumor size > 3 cm [hazard ratio (HR) = 1.482, 95%CI: 1.127-1.949; P = 0.005], positive nodal disease (HR = 1.701, 95%CI: 1.346-2.149; P < 0.001), poor differentiation (HR = 2.535, 95%CI: 1.839-3.493; P < 0.001), vascular invasion (HR = 1.542, 95%CI: 1.082-2.197; P = 0.017), and positive margins (HR = 1.798, 95%CI: 1.314-2.461; P < 0.001) had poor OS outcome. The independent factors for DFS were positive nodal disease (HR = 3.383, 95%CI: 2.633-4.348; P < 0.001), poor differentiation (HR = 2.774, 95%CI: 2.012-3.823; P < 0.001), vascular invasion (HR = 2.136, 95%CI: 1.658-3.236; P < 0.001), and positive margins (HR = 1.835, 95%CI: 1.256-2.679; P < 0.001). Multiple logistic regression analysis showed that caudate lobectomy [odds ratio (OR) = 9.771, 95%CI: 4.672-20.433; P < 0.001], tumor diameter (OR = 3.772, 95%CI: 1.914-7.434; P < 0.001), surgical procedures (OR = 10.236, 95%CI: 4.738-22.116; P < 0.001), American Joint Committee On Cancer T stage (OR = 2.010, 95%CI: 1.043-3.870; P = 0.037), and vascular invasion (OR = 2.278, 95%CI: 0.997-5.207; P = 0.051) were independently associated with tumor-free margin, and surgical procedures could indirectly affect survival outcome by influencing the tumor resection margin.
CONCLUSION: Tumor margin, tumor differentiation, vascular invasion, and lymph node status were independent factors for OS and DFS. Surgical procedures can indirectly affect survival outcome by influencing the tumor resection margin.
