Although serum bile acids and total cholesterol (TC) are closely related to liver cirrhosis, the potential diagnostic value of total bile acid-to-cholesterol ratio (TBA/TC) for liver fibrosis is unclear. The present study aimed to evaluate the value of TBA/TC in the diagnosis of cirrhosis and the relationship between TBA/TC and significant liver fibrosis in chronic hepatitis B virus (HBV) infected patients without cholestasis. 667 patients with alkaline phosphatase (ALP) ≤ 1.5 upper limit of normal (ULN) and gamma-glutamyl transferase (GGT) ≤ 3 ULN were rigorously included in this cross-sectional study. Liver biopsy was performed in 32 patients and METAVIR scoring system was used to evaluate liver fibrosis stage. Liver ultrasound elastography was performed in 138 patients, significant fibrosis was defined as fibrosis ≥ F2. Multiple logistic regression as well as receiver operating characteristic (ROC) curves analyses were performed. Compared to patients with non-cirrhosis, TBA and TBA/TC were significantly higher in cirrhosis while TC was significantly lower (all P

Published reports on laparoscopic resection of gastric gastrointestinal stromal tumor (GIST) were limited to small experiences and selection bias. Two hundred fourteen patients who underwent primary gastric GIST resection at our institution (January 2006–December 2012) were identified from a prospectively collected database. Laparoscopic resections (LAP) were performed in 133 patients, and open resections (OPEN) were performed in 81 patients. The short- and long-term outcomes were analyzed using propensity-score matching (PSM) by comparing the clinicopathological factors between these groups. The tumor resection method and tumor size were significantly different between the LAP and OPEN groups. After PSM, there were no differences (P > 0.05) in these clinicopathological factors. The LAP group had less blood loss and shorter operation time, time to first flatus, time to first fluid diet, time to gastric tube removal, and postoperative stay before PSM. In addition, there were no differences regarding the time of drainage tube removal or hospitalization expense. Other than the time of gastric tube removal, which was similar in these 2 groups, the short-term outcomes were similar before and after PSM. The rates of postoperative complications in the LAP and OPEN groups were 6.8% and 22.8%, respectively, before PSM (P = 0.001) and 5.6% and 22.5%, respectively, after PSM (P = 0.004). The multivariate analyses for complications showed that tumors were located in the middle of the stomach, and the operation method and proximal gastrectomy were independent risk factors before and after PSM. The 5-year cumulative survival rates in the LAP and OPEN groups were 95.4% and 85.9%, respectively, (P = 0.07) before PSM and 93.1% and 91.9%, respectively, (P = 0.69) after PSM (not significantly different). Laparoscopic resection for gastric GISTs had better short-term outcomes and similar long-term outcomes compared with open surgery. Localized gastric GISTs can be treated with laparoscopic surgery.

This article investigated the feasibility of laparoscopic surgery in unfavorable site gastric gastrointestinal stromal tumors (GISTs). We identified 214 patients who underwent primary gastric GIST resection at our institution (January 2006–December 2014) from a prospectively collected database. These patients were divided into a Favorable group (140 cases) and an Unfavorable group (74 cases) according to the 2014 version of the National Comprehensive Cancer Network Clinical Guidelines (NCCN guidelines). The wedge resection rate of the Favorable group was higher than that of the Unfavorable group, and most procedures were performed laparoscopically (P 0.05). The postoperative stay of the Unfavorable group was longer than that of the Favorable group (P = 0.02). Laparoscopic surgery in both groups resulted in a shorter operative time, lower blood loss, faster time to first flatus, faster time to first fluid diet, and shorter postoperative stay than open surgery (P 0.05). Furthermore, in the Unfavorable group, the 5-year OS and RFS were similar for both laparoscopic and open procedures. Multivariate Cox regression analysis showed that imatinib (IM) treatment was an independent risk factor for poor prognosis. Laparoscopic operation for gastric GISTs located in unfavorable sites can yield similar long-term outcomes compared with an open operation. However, laparoscopic surgery has the obvious advantage of being minimally invasive, and the incidence of postoperative complications was low. Laparoscopic surgery is thus an option for the treatment of localized gastric GISTs.
