Background: Laparoscopic splenectomy and azygoportal disconnection (LSD) is widely used for the treatment of esophagogastric variceal haemorrhage and hypersplenism owing to cirrhotic portal hypertension. However, whether LSD improves liver synthesis function and cirrhosis remains unclear. The aim of this study is to investigate the effect of LSD on liver synthesis function and cirrhosis based on a prospective 2-year follow-up study.Methods: A total of 118 patients with cirrhotic portal hypertension who underwent LSD were included in this study. We analysed clinical data including routine blood parameters, liver function, liver-synthesised proteins (antithrombin III, protein S, and protein C), liver fibrotic markers (type IV collagen (IV-C), procollagen type III (PC-III), laminin, and hyaluronidase), portal vein diameter, and portal blood flow velocity.Results: Postoperative portal vein diameter and portal blood flow velocity all showed gradual declines during the 2-year follow-up; compared with preoperative values, these were all significantly decreased from postoperative week (POW) 1 (all P < 0.001). Postoperative Child-Pugh scores and total bilirubin, albumin, international normalised ratio, antithrombin III, protein S, protein C, IV-C, PC-III, laminin, and hyaluronidase levels also all showed gradual improvements during the 2-year follow-up; compared with preoperative levels, these were all significantly improved from postoperative month (POM) 6, POW 1, POM 3, POM 3, POM 3, POM 6, POM 18, POW 1, POM 3, POM 24, and POM 18, respectively (all P < 0.05).Conclusion: LSD not only decreases portal hypertension and improves liver function, it also enhances liver synthesis function and reduces liver fibrosis.

Background: Posthepatitic cirrhosis is one of the leading risk factors for hepatocellular carcinoma (HCC) worldwide, among which hepatitis B cirrhosis is the dominant one. This study explored whether laparoscopic splenectomy and azygoportal disconnection (LSD) can reduce the risk of HCC among patients with hepatitis B virus (HBV)-related cirrhotic portal hypertension (CPH). Methods: A total of 383 patients with HBV-related CPH diagnosed as gastroesophageal variceal bleeding and secondary hypersplenism were identified in our hepatobiliary pancreatic center between April 2012 and April 2022, and conducted an 11-year retrospective follow-up. We used inverse probability of treatment weighting (IPTW) to correct for potential confounders, weighted Kaplan–Meier curves, and logistic regression to estimate survival and risk differences. Results: Patients were divided into two groups based on treatment method: LSD (n = 230) and endoscopic therapy (ET; n = 153) groups. Whether it was processed through IPTW or not, LSD group showed a higher survival benefit than ET group according to Kaplan–Meier analysis (P < 0.001). The incidence density of HCC was higher in the ET group compared to LSD group at the end of follow-up [32.1/1000 vs 8.0/1000 person-years; Rate ratio: 3.998, 95% confidence intervals (CI) 1.928–8.293]. Additionally, in logistic regression analyses weighted by IPTW, LSD was an independent protective predictor of HCC incidence compared to ET (odds ratio 0.516, 95% CI 0.343–0.776; P = 0.002). Conclusion: Considering the ability of LSD to improve postoperative survival and prevent HCC in HBV-related CPH patients with gastroesophageal variceal bleeding and secondary hypersplenism, it is worth promoting in the context of the shortage of liver donors.

Background: The optimal treatment options for gallstones together with common bile duct stones (CBDS) remain controversial. The aim of this study was to further compare the recurrence rate of stones after synchronous laparoscopic cholecystectomy combined with laparoscopic common bile duct exploration (SLCL) and synchronous laparoscopic cholecystectomy combined with intraoperative endoscopic sphincterotomy (SLCE) and to determine which option is more effective in reducing the rate of repeated recurrence of CBDS and the incidence rate of hepatolithiasis. Methods: We retrospectively investigated the clinical data of patients who underwent SLCL or SLCE at our hepatobiliary center between August 2012 and August 2020. The primary and secondary endpoints of this study were the recurrence of CBDS and the occurrence of hepatolithiasis, respectively. Results: In total, 1005 patients were enrolled in this study, including 431 patients in the SLCL group and 574 patients in the SLCE group. SLCL was associated with a significantly decreased rate of CBDS recurrence (4.18% vs. 7.84%, P = 0.018), repeated CBDS recurrence (0.70% vs. 3.00%, P = 0.010), and incidence of hepatolithiasis (0.00% vs. 1.05%, P = 0.040). Compared with SLCE, SLCL was an independent protective predictor of the recurrence of CBDS (relative risk, 0.505; 95% confidence interval, 0.286–0.891; P = 0.018) and repeated recurrence of CBDS (relative risk, 0.226; 95% confidence interval, 0.066–0.777; P = 0.018). Conclusions: SLCL is an optimal treatment option to SLCE for patients with gallstones combined with CBDS. [ABSTRACT FROM AUTHOR]

Background: Esophagogastric variceal bleeding is the most common lethal factor for patients with cirrhotic portal hypertension. We firstly developed a laparoscopic splenectomy and azygoportal disconnection (LSD) with intraoperative endoscopic variceal ligation (LSDL) technique. In this study, we aimed to evaluate whether LSDL is feasible and safe and whether LSDL can effectively prevent esophagogastric variceal re-bleeding (EVR), as compared with single LSD. Methods: In this randomized controlled single-center study, 88 patients with cirrhosis who had esophagogastric variceal bleeding and hypersplenism were randomly assigned to receive either LSD (n = 44) or LSDL (n = 44) between January 2020 and December 2021. The primary outcome was EVR. Results: No patients withdrew from the study. There were no significant differences in estimated blood loss, incidence of blood transfusion, time to first flatus and off-bed activity, or postoperative hospital stay between the two groups. Compared with that in the LSD group, operation time was significantly longer in the LSDL group (138.5 ± 19.4 min vs. 150.3 ± 19.0 min, P < 0.05); however, LSDL was associated with a significantly decreased EVR rate at 1-year follow-up (8/44 vs. 1/44, P < 0.05). Univariate analysis and multivariate logistic regression revealed that LSDL was a significant independent protective factor against EVR in comparison with LSD (relative risk: 0.105, 95% confidence interval 0.012–0.877; P = 0.037). Conclusions: Our newly developed LSDL procedure is not only technically feasible and safe; it also contributed to lowering the EVR risk more so than single LSD.

Background: The thrombosis of the main and intrahepatic branches of the portal vein (TMIP) is potentially lethal and deemed a common complication following laparoscopic splenectomy and azygoportal disconnection (LSD) in patients with cirrhosis and portal hypertension (PH). The predictors of TMIP after LSD remain unclear. The aim of this prospective study was to explore the predictive and risk factors for TMIP after LSD in cirrhotic patients with PH caused only by hepatitis B virus.Methods: From September 2014 to March 2017, we enrolled 115 patients with hepatitis B cirrhosis and PH who successfully underwent LSD. Patients were subdivided into a TMIP group and a non-TMIP group. Univariate and multivariate logistic regression analysis was conducted on 24 items of demographic and preoperative data, to explore the risk factors of TMIP.Results: Twenty-nine (25.22%) patients developed TMIP on postoperative day (POD) 7 and 26 (22.81%) patients developed TMIP on POD 30. From POD 7 to POD 30, 12 patients who did not have TMIP at POD 7 were newly diagnosed with TMIP, with portal vein diameter 15.05 ± 2.58 mm. Another 14 patients in whom TMIP had resolved had portal vein diameter 14.02 ± 1.76 mm. Univariate analysis and multivariate logistic regression revealed that portal vein diameter ≥ 13 mm [relative risk (RR) 5.533, 95% confidence interval (CI) 1.222-25.042; P = 0.026] and portal vein diameter ≥ 15 mm (RR 3.636, 95% CI 1.466-9.021; P = 0.005) were significant independent risk factors for TMIP on POD 7 and 30, respectively.Conclusion: Portal vein diameter ≥ 13 mm and ≥ 15 mm were significant independent predictors for TMIP after LSD in patients with hepatitis B cirrhosis and PH on POD 7 and POD 30, respectively.Trial Registration: We registered our research at https://www.Clinicaltrials: gov/ .

Background: Esophagogastric variceal re-bleeding (EGVR) is a common and potentially lethal complication after open or laparoscopic splenectomy and azygoportal disconnection (LSD) in patients with cirrhosis and portal hypertension. Currently, noninvasive biomarkers for predicting EGVR are lacking. This prospective study focused on developing a noninvasive and convenient clinical model for predicting postoperative EGVR. Methods: Between September 2014 and March 2017, we enrolled 164 patients with cirrhosis who successfully underwent LSD. Based on the absence or presence of EGVR, patients were divided into EGVR and non-EGVR groups. We used correlation analysis to determine significant candidate variables among the liver fibrotic markers procollagen type III (PC-III), hyaluronidase (HA), laminin (LN), and type IV collagen (C-IV). Results: Postoperative EGVR occurred in 22 (13.41%) patients. Correlation analyses showed that LN (r = 0.375; p < 0.001) and C-IV (r = 0.349; p < 0.001) were significantly positively associated with EGVR. The area under the receiver operating characteristic curve (AUC) of LN was 0.817 (95% confidence interval [CI] 0.722–0.913); that of C-IV was 0.795 (95% CI 0.710–0.881). In logistic multivariate regression, cutoff values LN ≥ 64 µg/L and of C-IV ≥ 65 µg/L were independent risk factors for EGVR. LN ≥ 64 µg/L combined with C-IV ≥ 65 µg/L was the best performing model, with AUC 0.867 (95% CI 0.768–0.967). Conclusion: LN and C-IV are potential markers to predict EGVR. Combining the two markers showed satisfactory ability to predict EGVR in patients with cirrhosis and portal hypertension after LSD. [ABSTRACT FROM AUTHOR]

Background: Digestive system complications are among the most important causes of postoperative poor quality of life after open and conventional laparoscopic splenectomy and azygoportal disconnection (CLSD). We firstly developed a modified vagus nerve-preserving laparoscopic splenectomy and azygoportal disconnection (MVLSD). In this study, we aimed to evaluate whether MVLSD is feasible and safe and to determine whether MVLSD can effectively eliminate postoperative digestive system complications, in comparison with CLSD. Method: In this randomized controlled single-center study, 60 patients with cirrhosis were randomly assigned to undergo either CLSD (n = 30) or MVLSD (n = 30) between April and December 2018. The primary outcome was delayed gastric emptying (DGE). Endoscopic physicians were blinded to group assignments. Results: One patient who received MVLSD withdrew from the study. There were no significant differences in intraoperative blood loss, incidence of blood transfusion, time to off-bed activity, time to first flatus, and postoperative hospital stay between the two groups. Compared with CLSD, operation time and incidences of DGE, diarrhea, epigastric fullness, and overall postoperative complications were all significantly reduced in the MVLSD group (all P < 0.05). Compared with CLSD, MVLSD was associated with significantly increased weight and albumin levels at 1, 6, and 12 months postoperatively versus preoperative values (all P < 0.05). The curative effect of resolving gastroesophageal variceal bleeding was similar between the groups. Conclusion: MVLSD is not only a technically feasible and safe procedure, it is also succinct and convenient. Furthermore, MVLSD effectively reduces postoperative digestive system complications, contributing to improved quality of life. [ABSTRACT FROM AUTHOR]
