Effect of preoperative jaundice on long-term prognosis of gallbladder carcinoma with radical resection.

PURPOSES: This study was designed to evaluate the effect of preoperative jaundice on long-term prognosis of gallbladder carcinoma (GBC) after radical resection (R0). METHODS: A total of 267 GBC patients who underwent R0 resection from January 2004 to December 2014 were enrolled, including 54 patients with preoperative jaundice and 213 patients without jaundice. The clinicopathological parameters between the two groups were compared, and the correlation between preoperative jaundice and the long-term prognosis was furtherly analyzed. RESULTS: Unilateral and multivariate analyses of 267 GBC patients showed that the depth of tumor invasion (pT stage), lymphatic metastasis, and hepatic invasion were independent prognostic factors. The univariate and multivariate analysis of 54 GBC patients with preoperative jaundice showed that only pT stage was an independent factor for prognosis. Furthermore, the intraoperative blood transfusion and pT stage were significant different between long-term survival (survive for more than 3 years) and those who died within 3 years (P < 0.05). CONCLUSION: Preoperative jaundice was not the independent factor resulting in the poor long-term prognosis of gallbladder carcinoma after R0 resection. The pT stage was the only long-term prognostic factor in all GBC patients regardless of preoperative jaundice.

Case-control study of the efficacy of retrogastric Roux-en-Y choledochojejunostomy.

The traditional, retrocolic/antegastric Roux-en-Y choledochojejunostomy is technically complicated, and the incidence of postoperative complications remains high. Here we report the outcome of 59 consecutively treated patients (study group, SG) that underwent a new choledochojejunostomy method in which the jejunal loop is passed behind the antrum pyloricum (retrogastric route). A retrospective comparison was made between this group of patients and 187 patients (control group, CG) that underwent conventional Roux-en-Y choledochojejunostomy (antegastric route). Baseline clinicopathological characteristics were similar in both groups, except for the BMI, which was significantly higher in the SG. The time spent on constructing the anastomosis, as well as overall postoperative complications, did not differ between groups. Compared with the CG, the incidence of postoperative delayed gastric emptying was decreased in the SG, and the time elapsed before the patients' first postoperative liquid food consumption was shorter. We ascribe these beneficial effects to the superiority of the modified, retropyloric choledochojejunostomy approach, and propose that this surgical technique is particularly suitable for obese patients, especially those with a short ascending bowel loop.

Nomograms for survival prediction in patients undergoing liver resection for hepatitis B virus related early stage hepatocellular carcinoma.

BACKGROUND: The long-term outcomes of patients who underwent liver resection (LR) for early-stage hepatitis B virus (HBV)-related hepatocellular carcinomas (HCCs) are difficult to predict. This study aimed to develop two nomograms to predict postoperative disease-free survival (DFS) and overall survival (OS), respectively. METHODS: Data on a primary cohort of 1328 patients who underwent LR for HBV-related HCCs within Milan criteria at the Eastern Hepatobiliary Surgery Hospital (EHBH) from 2000 to 2006 were used to develop the nomograms by the Cox regression analyses. An internal validation cohort of 442 patients operated from 2006 to 2011 at the EHBH and an external validation cohort of 474 patients operated from 2007 to 2009 at the Zhongshan Hospital were used for validation studies. Discrimination and calibration were measured using concordance index (C-index), calibration plots and Kaplan-Meier curves. RESULTS: The independent predictors of DFS or OS which included tumour stage factors, biomarker and HBV-DNA level were respectively incorporated into the two nomograms. In the primary cohort, the C-indexes of the models in predicting DFS and OS were 0.76 (95% confidence interval: 0.75-0.78) and 0.79 (0.77-0.81), respectively. The calibration curves fitted well. Both nomograms accurately stratify patients into four distinct incremental prognostic subgroups. The C-indexes of the nomogram for OS prediction was significantly higher than those of the six conventional staging systems (0.65-0.71, all P<0.001). These results were verified by the internal and external validations. CONCLUSION: The proposed nomograms showed good prognostication for patients with early HBV-related HCCs after hepatectomy.
