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.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.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).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.We registered our research at https://www.gov/ .

In Asia, laparoscopic splenectomy and azygoportal disconnection (LSD) has been widely regarded as a preferential treatment modality for cirrhotic portal hypertension (PH). However, LSD involves high surgical risk, technical challenges, and many potential postoperative complications. Technology optimization and innovation in LSD aiming to solve to these difficulties has scarcely been reported. In this retrospective study, we aimed to evaluate the clinical therapeutic effect of our cluster technology optimization and innovation on LSD for PH.From February 2012 to January 2020, 500 patients with cirrhosis who had esophagogastric variceal bleeding and hypersplenism underwent LSD in our department. According to different operation periods, patients were divided into the early-, intermediate-, and late-period groups. We collected information regarding clinical characteristics of all patients as well as their preoperative and postoperative follow-up data.Compared with the early-period group, operation time and postoperative hospital stay were all significantly different and gradually declined from the intermediate- and late-period groups, respectively (all P lt; 0.05). Intraoperative blood loss of these three groups was gradually decreased, with significant differences (P lt; 0.05). The incidences of delayed gastric emptying and diarrhea in the late-period group were all significantly lower than those in the early- and intermediate-period groups, respectively (all P lt; 0.05). Compared with the early-period group, the incidence of variceal re-bleeding was significantly lower in the intermediate- and late-period groups (all P lt; 0.05).Our cluster technology optimization and innovation of LSD not only contributed to faster recovery and fewer complications but also enhanced surgical safety for patients. It is worth promoting this approach among patients with EVB and hypersplenism secondary to cirrhotic PH.

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. 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. 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. 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.

How to precisely protect and preserve anterior and posterior vagal trunks and all their branches during the procedure of splenectomy and azygoportal disconnection is studied rarely. We firstly developed a vagus nerve-guided robotic-assisted laparoscopic splenectomy and azygoportal disconnection (VGRSD). The aim of this study was to evaluate whether VGRSD is feasible and safe and to determine whether VGRSD can effectively eliminate postoperative digestive system complications by protecting vagal nerve precisely.In this prospective clinical study, 10 cirrhotic patients with oesophagogastric variceal bleeding and hypersplenism who underwent VGRSD between January 2022 and March 2022 were gathered, and compared with a retrospective cohort who received a part of the vagus nerve-preserving robotic-assisted laparoscopic splenectomy and azygoportal disconnection (VPRSD). They were all followed up for 6 months.In VGRSD group, the operation time was 173.5 ± 16.2 min, blood loss was 68.0 ± 39.1 ml, VAS pain score on the first day was 1.9 ± 0.7, and the postoperative hospital stay was 7.7 ± 0.7 days. There was no incisional complications, pneumonia, gastric fistula, pancreatic fistula, and abdominal infection. No patients suffered from diarrhoea, delayed gastric emptying, and epigastric fullness. Compared with VPRSD, operation time was significantly longer for VGRSD (p 0.05). However, VGRSD was significantly associated with less diarrhoea and shorter postoperative hospital stay (all p 0.05).VGRSD procedure is not only technically feasible and safe, it also effectively eliminate postoperative digestive system complications.We registered our research at https://www.gov/.

About 10%-20% of all individuals who develop hepatocellular carcinoma (HCC) do not have cirrhosis. Comparisons are rarely reported regarding the effectiveness of radiofrequency ablation (RFA) and liver resection (LR) in survival of HCC without cirrhosis and stratification by tumor size ≤ 5 cm.We used the Surveillance, Epidemiology, and End Results (SEER) database and identified 1505 patients with a solitary HCC tumor ≤ 5 cm who underwent RFA or LR during 2004-2015. Patients were classified into non-cirrhosis and cirrhosis groups and each group was categorized into three subgroups, according to tumor size (≤ 30 mm, 31-40 mm, 41-50 mm).In patients without cirrhosis, LR showed better 5-year HCC cancer-specific survival than RFA in all tumor size subgroups (≤ 30 mm: 82.5% vs. 56.4%; 31-40 mm: 71.3% vs. 46.8%; 41-50 mm: 74.7% vs. 37.5%; all P0.05). Compared with RFA, LR was an independent protective factor for HCC cancer-specific survival in multivariate Cox analysis [≤ 30 mm: hazard ratio (HR) = 0.533, 95% confidence interval (CI): 0.313-0.908; 31-40 mm: HR = 0.439, 95% CI: 0.201-0.957; 41-50 mm: HR = 0.382; 95% CI: 0.159-0.916; all P0.05]. In patients with cirrhosis, for both tumor size ≤ 30 mm and 31-40 mm groups, there were no significant survival differences between RFA and LR in multivariate analysis (all P0.05). However, in those with tumor size 41-50 mm, LR showed significantly better 5-year HCC cancer-specific survival than RFA in both univariate (54.7% vs. 23.1%; P0.001) and multivariate analyses (HR = 0.297; 95% CI: 0.136-0.648; P = 0.002).RFA is an inferior treatment option to LR for patients without cirrhosis who have a solitary HCC tumor ≤ 5 cm.

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. 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. 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

Robotic surgery has been widely accepted in many kinds of surgical procedures. Little is known about clinical effects of robotic-assisted splenectomy and azygoportal disconnection (RSD) for gastroesophageal variceal bleeding and secondary hypersplenism owing to cirrhotic portal hypertension. The aim of this study was to evaluate whether RSD is feasible and safe for patients with cirrhotic portal hypertension and whether RSD is superior to laparoscopic splenectomy and azygoportal disconnection (LSD). We retrospectively investigated the clinical effects of 50 patients with cirrhosis who underwent vagus nerve-preserving RSD (n = 20) and LSD (n = 30) between September 2020 and October 2021. We compared patients' demographic, intraoperative, and perioperative variables. RSD and LSD were successful in all patients. Operative time did not differ significantly between the RSD group and LSD group (151.15 ± 21.78 min vs. 144.50 ± 24.30 min, P 0.05), but intraoperative blood loss were significantly reduced in the RSD group (61.00 ± 34.93 mL vs. 105.00 ± 68.77 mL, P 0.05). No statistically significant differences were found regarding intraoperative allogeneic transfusion rate, visual analog scale pain score on the postoperative first day, time to first oral intake, initial passage of flatus, initial off-bed activity, postoperative hospital stay, and overall perioperative complication rate (all P 0.05). In conclusion, RSD is not only a technically feasible and safe procedure but it was associated with less blood loss than LSD for cirrhotic portal hypertension with gastroesophageal variceal bleeding and secondary hypersplenism.

BACKGROUND: The prognosis for patient survival using the tumor–node–metastasis (TNM) staging system may be imperfect, as it based only on biological factors and does not include the socioeconomic factors (SEFs). We integrated the SEFs into the TNM system (TNM-SEF), and evaluated whether the novel TNM-SEF staging system showed better prediction capacity and improved clinical guidance in hepatocellular carcinoma (HCC). METHODS: We selected data of 12 514 cases with HCC between 2010 and 2015 from the SEER database. The Kaplan–Meier survival curves and Cox proportional hazards regression were used to analyze cancer-specific survival (CSS) among the TNM-SEF stages. RESULTS: Multivariate Cox analyses showed that insurance status, marital status, year of diagnosis, and income were prominent prognostic SEFs (all P < .05). When compared with the SEF0 stage, the SEF1 stage was significantly associated with a 36.1% increased risk of cancer-specific mortality in HCC overall, a 22.2% increased risk of metastatic HCC, and a 41.8% increased risk of non-metastatic HCC (all P < .001). The concordance index of the TNM-SEF stage (0.768) was better than that of the TNM stage (0.764). Furthermore, patients with SEF0 stage showed higher 5-year CSS than those with SEF1 stage (I: 48.7% vs. 28.1%; II: 41.0% vs. 25.1%; IIIA: 12.8% vs. 5.0%; IIIB: 7.8% vs. 6.0%; IIIC: 6.4% vs. 6.7%; IVA: 8.4% vs. 2.5%; IVB: 2.1% vs. 0.8%; all P < .05). CONCLUSION: We have proved that the SEF stage is an independent predictor for HCC. The combined SEF stage with TNM staging warrants more clinical attention, for improved prognostic prediction and clinical guidance.

Background: Surgery for pancreatic cancer with liver metastases (PCL) is not recommended in the international guidelines, and investigation of its clinical significance in patients with PCL is very limited. This study explored whether surgery, especially synchronous resection of the primary tumor and liver metastases (SPL), could improve survival in PCL. Methods: Data of 14,248 patients with PCL from Surveillance, Epidemiology, and End Results database was analyzed. Patients were divided into following groups: SPL, synchronous primary site, and other resection (SPO), single resection of the primary site (SPS), and no resection (NR). Results: In this study, only 93 (0.7%) underwent SPL, 88 (0.6%) for SPO, and 232 (1.6%) for SPS. Multivariate Cox analysis showed surgical procedures of both the primary site and other sites were independent protective prognostic factors for pancreatic cancer cause-specific survival (PCSS) (all P < 0.001). Patients in the SPL group showed the most survival benefit, with a significant and gradually increased difference as compared with the SPO, SPS, and NR groups (median survival: 54, 34, 15, and 3 months, respectively, all P < 0.001). Compared with the NR group, mortalities were significant and gradually declining in the SPS, SPO, and SPL groups, with hazard ratio 0.329 (95% confidence interval [CI], 0.281 to 0.386), 0.220 (95% CI, 0.164 to 0.294), and 0.162 (95% CI, 0.118 to 0.222), respectively (all P < 0.001). Conclusions: Surgical procedures for both primary site and other sites improved survival. SPL, particularly, showed a considerable survival benefit in well-selected patients with PCL.

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. 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). Postoperative EGVR occurred in 22 (13.41%) patients. Correlation analyses showed that LN (r = 0.375; p

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. 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. 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

We retrospectively studied Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 10,568 patients with GBC who underwent surgical treatment from 1980 to 2013. The patients were categorized according to age at diagnosis: 5-cm tumors, a lower prevalence of a localized SEER stage, a higher number of lymph nodes dissected (≥2 nodes), and a lower proportion of tumors among patients with a widowed marital status, all of which were statistically significant within-group differences ( P < 0.001). Age at diagnosis was an independent prognostic factor in the multivariate analysis ( P < 0.001). The 5-year gallbladder cancer cause-specific survival rate was 26.7% in the young group and 16.2% in the old group, which showed statistical significance in both the univariate and multivariate analysis ( P < 0.001). Conclusions Young patients with GBC treated with surgical resection appear to have unique characteristics and a higher cancer-specific survival rate than older patients, although they showed a higher rate of poor biological behavior and advanced-stage disease.
