Application of a virtual ruler in predicting postoperative rebleeding from esophageal varices in patients with liver cirrhosis.

BACKGROUND: Esophageal variceal diameter (EVD) is one of the most important predictors of variceal bleeding, as well as an important predictor of the effectiveness of endoscopic esophageal varices (EV) treatments. EVD is currently determined using visual inspection by endoscopic operators, meaning that results can vary widely between operators. This approach also means that cases unsuitable for endoscopic variceal ligation (EVL) can be complicated by postoperative hemorrhage. Thus, the purpose of this study was to explore the value of a virtual ruler (VR) in predicting rebleeding after the endoscopic treatment of EV in patients with cirrhosis. METHODS: We enrolled 588 patients with cirrhosis and EV (with and without gastric varices), who were treated with EVL or endoscopic injection sclerotherapy across 3 hospitals. We categorized participants into 2 groups, a nonbleeding group and a rebleeding group, according to whether they bled again after surgery. We compared basic demographic and clinical data, laboratory tests, EVD, and treatment modalities between the 2 groups. Potential risk factors for rebleeding after EV operations were analyzed using univariate and multivariable regression analyses. Correlations between esophageal variceal rebleeding and EVD were also analyzed, as was the consistency between visual EVD estimates and EVD measured using a VR. RESULTS: Child-Pugh class, albumin (ALB) levels, prothrombin time (PT), EVD (visual value), EVD (VR value), red sign, and the number of laps used for EVL showed statistically significant differences between the rebleeding and nonbleeding groups. Univariate regression analysis showed that Child-Pugh classification, ALB levels, PT, EVD (VR value), and red sign were strongly associated with rebleeding after endoscopic treatment of EV, whereas multivariable regression analysis showed that Child-Pugh classification, ALB levels, and EVD (VR value) were predictive factors for rebleeding after endoscopic treatment of EV. Differences between visual EVD estimates and VR EVD measurements were large. (Kappa value: 0.391, P < .001). However, the 2 methods showed high agreement for EVD >1 cm (87/95) CONCLUSION: EVD (VR value) can more accurately predict rebleeding rates. It can also provide a basis for selecting appropriate endoscopic treatment modalities for EV and effectively circumvent postoperative EV rebleeding.

Comparison of Endoscopic Ultrasound-guided Cyanoacrylate Injection and Transjugular Intrahepatic Portosystemic Shunt in the Prevention of Gastric Varices Rebleeding.

OBJECTIVE: The purpose of this study was to investigate the efficacy and safety of endoscopic ultrasound (EUS)-guided injection of cyanoacrylate (CYA) and transjugular intrahepatic portal shunts (TIPSs) in the treatment of patients with cirrhosis with ruptured gastric varices. METHODS: In this retrospective study, 105 patients with liver cirrhosis and gastric varicose veins who were admitted to the First Affiliated Hospital of Anhui Medical University between April 2018 and April 2023 without nonselective ß-blockers treatment and no portal vein thrombosis were evaluated. The patients were divided into the transjugular intrahepatic portal shunt (TIPS) group (n = 60) and the EUS-CYA group (n = 45) for the purpose of evaluating postoperative rebleeding rates, complications, survival rates, and other factors. RESULTS: During the follow-up, there was no significant difference in the rebleeding rates between the TIPS group and EUS-CYA group within 3 months (5% vs 2.2%; P= 0.825; 10% vs 20%, P= 0.147). However, the TIPS group had significantly lower rebleeding rates than the EUS-CYA group at 6 months (10% vs 33.3%; P= 0.030) and 1 year or longer (11.7% vs 42.2%; P < 0.01). In terms of hepatic encephalopathy, the incidence rate of the TIPS group was significantly higher than that of the EUS-CYA group (20% vs 2.2%; P= 0.006). In addition, there was no difference in the survival rates between the two groups (93.3% vs 97.8%; P= 0.552). CONCLUSIONS: TIPS is superior to EUS in preventing rebleeding in patients with ruptured varices of the fundus, but it has a higher incidence of hepatic encephalopathy, and there is no difference in long-term survival between the two groups.

Correlation between diameter of esophageal varices and early rebleeding following endoscopic variceal ligation: a multicenter retrospective study based on artificial intelligence-based endoscopic virtual rule.

Background and objective: Bleeding following endoscopic variceal ligation (EVL) may occur as a result of numerous factors, including a diameter of esophageal varices (EV) that is too large to be completely ligated. The present study aimed to develop an artificial intelligence-based endoscopic virtual ruler (EVR) to measure the diameter of EV with a view to finding more suitable cases for EVL. Methods: The present study was a multicenter retrospective study that included a total of 1,062 EVLs in 727 patients with liver cirrhosis with EV, who underwent EVL from April 2016 to March 2023. Patients were divided into early rebleeding (n = 80) and non-rebleeding groups (n = 982) according to whether postoperative bleeding occurred at 6 weeks. The characteristics of patient baseline data, the status of rebleeding at 6 weeks after surgery and the survival status at 6 weeks after rebleeding were analyzed. Results: The early rebleeding rate following 1,062 EVL procedures was 7.5%, and the mortality rate at 6 weeks after bleeding was 16.5%. Results of the one-way binary logistic regression analysis demonstrated that the risk factors for early rebleeding following EVL included: high TB (P = 0.009), low Alb (P = 0.001), high PT (P = 0.004), PVT (P = 0.026), HCC (P = 0.018), high Child-Pugh score (P < 0.001), Child-Pugh grade C(P < 0.001), high MELD score(P = 0.004), Japanese variceal grade F3 (P < 0.001), diameter of EV (P < 0.001), and number of ligature rings (P = 0.029). Results of the multifactorial binary logistic regression analysis demonstrated that Child-Pugh grade C (P = 0.007), Japanese variceal grade F3 (P = 0.009), and diameter of EV (P < 0.001) may exhibit potential in predicting early rebleeding following EVL. ROC analysis demonstrated that the area under curve (AUC) for EV diameter was 0.848, and the AUC for Japanese variceal grade was 0.635, which was statistically significant (P < 0.001). Thus, results of the present study demonstrated that EV diameter was more optimal in predicting early rebleeding following EVL than Japanese variceal grade criteria. The cut-off value of EV diameter was calculated to be 1.35 cm (sensitivity, 70.0%; specificity, 89.2%). Conclusion: If the diameter of EV is ≥1.4 cm, there may be a high risk of early rebleeding following EVL surgery; thus, we recommend caution with EVL.

The Value of Follow-Up Liver Stiffness Changes Measured by Virtual Touch Quantification Elastography for Predicting Recurrence of Gastroesophageal Varices after Endoscopic Injection Sclerotherapy on Cirrhotic Patients.

Background and Aims: Recurrence of gastroesophageal varices (GEVs) after sclerotherapy is a public health problem. However, mass screening of recurrence of GEVs through gastroscopy is a high-cost procedure. We aim to evaluate the changes in liver stiffness (LS) over time after endoscopic injection sclerotherapy (EIS) and determine its value in predicting the recurrence of GEVs. Methods: One hundred and thirty-five patients with GEVs who underwent EIS treatment were included in this study. The patients were divided into two groups, namely, the nonrecurrence and recurrence groups, based on endoscopic findings at 6 months after discharge. LS measurements were obtained on five occasions. Repeated measure analysis of variance was employed to assess LS differences at different time points and compare them between the two groups. Results: The LS values during the 6-month postdischarge period were consistently higher than the baseline value (measured on the day of hospitalization). The recurrence group demonstrated sustained elevated LS levels throughout the 6-month follow-up period, while the nonrecurrence group showed a gradual decline in LS. The difference in LS trend between the two groups was statistically significant (P = 0.04). The area under the curve (AUC) values for LS differences were 0.806, with a corresponding 95% confidence interval (CI) of 0.640-0.918 and a cut-off value of 0.556, indicating their potential utility in predicting GEV recurrence. Conclusions: Longitudinal assessment of LS values in post-EIS patients can provide valuable information for predicting the recurrence of GEVs.

Application of Indian ink markers for locating gastric varices under endoscopic ultrasonography.

OBJECTIVE: The present study aimed to investigate the accuracy of endoscopic ultrasonography (EUS) combined with Indian ink in locating target vessels of gastric varices (GVs) compared with conventional endoscopic techniques. Additionally, the characteristics of GVs under conventional endoscopy were also explored. METHODS: All 50 cirrhotic patients with GVs between August 2021 and December 2022 were included in the study. Firstly, conventional endoscopy was employed to identify GVs and to record the expected injection sites. Subsequently, EUS was used to locate the perforated vessel and the injection site was them marked with India ink followed by injection with cyanoacrylate (CYA). Finally, conventional endoscopy was used to examine GVs, to identify the marker points of Indian ink and to compare whether the injection points under conventional endoscopy were consistent with those marked with Indian ink. Furthermore, patients with consistent and inconsistent distribution of endoscopic markers and injection sites were divided into two groups. RESULTS: EUS could detect the perforating vessels in real time and intuitively. The distribution of markers using EUS was significantly different compared with the injection points obtained by conventional endoscopy (P < 0.001). Therefore, 20 cases were allocated to the consistent group and 30 cases to the non-consistent group. 16 patients who showed red wale signs were obtained in the consistent group and 11 patients in the non-consistent group (P = 0.048). The diameter of the largest GVs was 13.5 (10-15) mm in the consistent group compared with 10 (7.5-10) mm in the non-consistent group (P = 0.006). CONCLUSION: EUS could provide the exact location of GVs, thus more accurately describing the endoscopic characteristics of the GVs. Furthermore, the red wale signs and diameter of the largest GVs obtained using conventional endoscopy were helpful in determining the location of target GVs.

Endoscopic ultrasonography-guided injection of cyanoacrylate in the treatment of gastroesophageal varices type 1: a single-center randomized study.

BACKGROUND AND AIM: First, it has been demonstrated that endoscopic ultrasonography (EUS)-guided cyanoacrylate (CYA) injection (EUS-CYA) has greater efficacy than direct endoscopic injection of cyanoacrylate (DEI-CYA) for treating type 1-isolated gastric varices. However, it is necessary to conduct further studies to determine whether EUS has any advantage over the current guidelines for treating gastroesophageal varices type 1 (GOV1). Second, liver function is an important prognostic factor in patients with liver cirrhosis. Therefore, we evaluated the liver function of patients treated with EUS-CYA. METHODS: In a single-center study, a prospective cohort from February 2021 to September 2022 involving 89 patients with cirrhosis with GOV1 were assigned to undergo EUS-CYA (n = 45) or DEI-CYA (n = 44). The success rate of CYA injection, the rate of overall rebleeding, the rate of reintervention, the complications during the follow-up period, and the liver function were compared. RESULTS: In both groups, 100% of the operations were successful. The follow-up time of the two groups was 290 (153-398) days and 267 (177-416) days, respectively. In the EUS group, the perforating veins had an average diameter of 7.0 ± 2.7 mm, and they had a 100% occlusion rate. A statistically significant difference was found between the two groups regarding the number of sessions needed to eradicate GV (p = 0.005, pairwise comparisons were conducted using the Bonferroni correction method.), the late rebleeding rate after EUS-CYA [n = 3 (6.7%) vs n = 10 (22.7%); p = 0.032], and the incidence of postinjection ulcers [n = 4 (8.9%) vs n = 12 (27.3); p = 0.023)]. Following EUS or DEI-CYA treatment, the patient's liver function did not show any significant deterioration or decline. CONCLUSION: EUS-CYA has a higher eradication success rate and fewer complications, recurrences, and rebleeding episodes than DEI-CYA used for GOV1 treatment. In addition, EUS-CYA did not impair liver function.

Balloon-occluded Esophageal Varices Obliteration Versus Ligation for the Management of F2 Esophageal Varices: A Randomized Controlled Trial.

AIM: To compare balloon-occluded esophageal varices obliteration (BEVO) with esophageal variceal ligation (EVL) in the management of cirrhotic patients with type F2 esophageal varices (F2-EVs). MATERIALS AND METHODS: A total of 157 patients with F2-EVs were randomly assigned to either BEVO (n=79) or EVL (n=78) group in the prospective study between July 2021 and December 2021. Primary outcomes included recurrence and eradication rates. Secondary outcomes included rebleeding rate, and procedural complications. RESULTS: The recurrence rate of EVs was notably lower in the BEVO group than in the EVL group (3.80% vs. 21.79%; P =0.001). The rate of complete eradication in the BEVO group was significantly higher than that of the EVL group (96.20% vs. 74.36%; P <0.001). The incidence of rebleeding in the BEVO group was markedly lower than that of the EVL group (7.59% vs. 20.51%; P =0.02). There was a higher incidence of transient dysphagia in the EVL group than in the BEVO group (10.26% vs. 1.27%; P =0.015). CONCLUSIONS: BEVO exerted an effective treatment option for F2-EVs.

Clinical outcomes of clip-assisted endoscopic cyanoacrylate injection versus conventional endoscopic cyanoacrylate injection in treating gastric varices with a gastrorenal shunt.

BACKGROUND AND STUDY AIMS: The optimal treatment for gastric varices (GVs) is a topic that remains definite for this study. This study compared the clinical outcomes of clip-assisted endoscopic cyanoacrylate injection (clip-ECI) to conventional endoscopic cyanoacrylate injection (con-ECI) for the treatment of GVs with a gastrorenal shunt. PATIENTS AND METHODS: Data were collected retrospectively in five medical centers from 2015 to 2020. The patients were treated with con-ECI (n = 126) or clip-ECI (n = 148). Clinical characteristics and procedural outcomes were compared. Patients were followed until death, liver transplantation or 6 months after the treatment. The primary outcome was rebleeding, and the secondary outcome was survival. RESULTS: There were no significant differences in age, sex, etiology, shunt diameter and Child-Pugh classification between the two groups. Fewer GVs obliteration sessions were required in the clip-ECI group than in the con-ECI group (p = 0.015). The cumulative 6-month rebleeding-free rates were 88.6% in the clip-ECI group and 73.7% in the con-ECI group (p = 0.002). The cumulative 6-month survival rates were 97.1% in the clip-ECI group and 94.8% in the con-ECI group (p = 0.378). CONCLUSIONS: Compared with con-ECI, clip-ECI appears more effective for the treatment of GVs with a gastrorenal shunt, which required less sessions and achieved a higher 6-month rebleeding-free rate.

Balloon-compression endoscopic injection sclerotherapy versus transjugular intrahepatic portosystemic shunt for esophageal variceal rebleeding.

BACKGROUND: In cirrhotic patients, recurrent bleeding after the first episode of esophageal variceal bleeding (EVB) is common and lethal. The present study was aimed to compare balloon-compression endoscopic injection sclerotherapy (bc-EIS) with transjugular intrahepatic portosystemic shunt (TIPS) for the prophylaxis of variceal rebleeding. METHODS: Between June 2020 and September 2022, 81 cirrhotic patients with EVB (42 in the bc-EIS group and 39 in the TIPS group) were evaluated retrospectively. The occurrence of rebleeding, hepatic encephalopathy (HE) or other complications, as well as liver functions and survival rate were compared between two groups. RESULTS: During the 12 months of follow-up, variceal eradication was achieved in 40 (95.24%) patients of the bc-EIS group after a mean of 1.80 ± 0.94 sessions. TIPS was successfully performed in 39 (100%) patients. No significant difference in the variceal rebleeding rate was observed between bc-EIS and TIPS groups (16.67 vs. 17.95%; p = 0.111). While the bc-EIS group showed significantly decreased incidence of HE (2.38 vs. 17.95%; p < 0.001) and lower level of total bilirubin (p < 0.05) in comparison with the TIPS group. The difference in mortality between the two groups failed to reach statistical significance (0.00 vs. 7.69%; p = 0.107). CONCLUSION: Bc-EIS is not inferior to TIPS in the survival and control of variceal rebleeding, but associated with decreased risk of HE and liver dysfunction.

A Noninvasive Technology Using Artificial Intelligence to Measure the Diameter of Esophageal Varices Under Endoscopy.

BACKGROUND: The diameter of esophageal varices (EVs) can not only predict variceal bleeding episodes but is also considered to be a significant factor in determining the endoscopic treatment of EVs. At present, visual observation is the most common method for estimating the diameter of EVs, the results of which may vary greatly between endoscopists. MATERIALS AND METHODS: Herein, a noninvasive measurement technology, a virtual ruler (VR), was designed using artificial intelligence. The diameter and pressure of EVs in 7 patients were measured using VR and an esophageal varix manometer (EVM). Statistical methods, including the Bland-Altman Plot and Pearson correlation coefficient analysis, were used to compare the aforementioned 2 methods. RESULTS: The results showed that the diameter of EVs measured using the aforementioned 2 methods did not differ. In addition, the time taken to measure the diameter of EVs using VR was 31 seconds (range, 25 to 44 s), significantly shorter compared with 159 seconds (range, 95 to 201 s) taken using an EVM ( P < 0.01). Furthermore, the diameter of EVs measured using an EVM exhibited a high linear correlation with pressure. CONCLUSIONS: The current study demonstrated that VR was more accurate in measuring the diameter of EVs compared with EVMs while reducing unnecessary early intervention and the risk of complications. In terms of clinical risk and economic cost, this technology is hardly a burden. Overall, VR could be a useful software for the endoscopic detection and treatment of EVs in patients with liver cirrhosis.

Analysis of Complications and Risk Factors Other than Bleeding before and after Endoscopic Treatment of Esophagogastric Variceal Bleeding in Patients with Liver Cirrhosis.

Objective: To identify any concomitant complications other than bleeding (COTB) before and after endoscopic treatment of esophagogastric variceal bleeding (EGVB) in liver cirrhosis patients and explore the underlying risk factors. Materials and Methods: Cirrhotic patients complicated with EGVB, who underwent interventional endoscopic treatments in our hospital from November 2017 to August 2020, were enrolled in this study. Clinical data were retrospectively analyzed for COTB at admission and within 2 years of the first endoscopic treatment. Patients were screened for potential risk factors of COTB before and after the treatment. Univariate analysis was performed to identify clinical factors of secondary complications, and statistically significant factors were included in the multivariate Cox and logistic regression analyses. Results: Of the 547 patients with cirrhosis, 361 individuals had COTB in the first endoscopic treatment. In this cohort, the top 3 prevalent incidences were portal vein thrombosis (PVT) or spongiosis, cholelithiasis, and pathogenic infections. The COTB did not occur at admission in 171 liver cirrhosis patients but happened at the follow-up. Higher Child-Pugh scores indicated potential risks of multiple concurrent complications, including bleeding. Risk factors for concomitant PVT or cavernous changes after endoscopic treatment of EGVB, pathogenic infections, and cholelithiasis could prolong the cirrhosis symptoms, while noncholestatic cirrhosis patients might have a lower risk than posthepatitis B cirrhosis patients, in the context of a higher degree of EGV and serum level of D-D and a lower blood calcium level. Conclusions: Clinical treatment and interventions can be tailored to avoid other complications during and after EGVB treatment, which can affect the outcome and prognosis of bleeding symptoms.

Mucosal-Associated Invariant T Cells in the Digestive System: Defender or Destroyer?

Mucosal-associated invariant T (MAIT) cells are a subset of innate T lymphocytes that express the semi-invariant T cell receptor and recognize riboflavin metabolites via the major histocompatibility complex class I-related protein. Given the abundance of MAIT cells in the human body, their role in human diseases has been increasingly studied in recent years. MAIT cells may serve as targets for clinical therapy. Specifically, this review discusses how MAIT cells are altered in gastric, esophageal, intestinal, and hepatobiliary diseases and describes their protective or pathogenic roles. A greater understanding of MAIT cells will provide a more favorable therapeutic approach for digestive diseases in the clinical field.

Balloon-Occluded Esophageal Variceal Obliteration Procedure: A Novel Technique Report from Three Centers.

Introduction: Esophageal variceal bleeding (EVB) is a potentially fatal complication of cirrhosis. The purpose of the present study was to evaluate the safety and efficacy of a novel technique of balloon-occluded esophageal varices (EVs) obliteration (BEVO) for EVs classified as F2 (medium size, F2-EVs) and F3 (large size, F3-EVs). Materials and Methods: Between December 2020 and December 2021, a total of 73 consecutive patients with EVs were treated using BEVO. An injection of sclerosant was administered via direct puncture of the varices during balloon occlusion. Immediate postprocedural Doppler endoscopic ultrasonography (EUS) was conducted to evaluate the blood flow in the EVs. Several factors, including the technical success, controlling of acute bleeding, intraoperative bleeding at the injection site, variceal eradication, variceal recurrence, and BEVO-related complications, were assessed. Results: BEVO was successfully performed in all patients. Immediate hemostasis was achieved in 100% (25/25) of patients with active EVB. The incidence of injection site intraoperative bleeding presenting as oozing and spurting bleeding was 76.71% (56/73) and 8.22% (6/73), respectively. Based on Doppler EUS and endoscopic examination, EVs were completely eradicated in 71 out of 73 patients (97.26%) after three sessions. A total of 3 (4.11%) patients were diagnosed with EV recurrence during follow-up after complete EV eradication. Retrosternal chest discomfort (13.70%; 10/73) and abdominal bloating (2.74%; 2/73) were spontaneously relieved after a few days. No serious BEVO-related complications were observed. Discussion: BEVO is a convenient and effective treatment for obliterating F2 and F3 EVs. Clinical Trial Registration No. ChiCTR2000039974.

Automatic detection of early gastric cancer in endoscopy based on Mask region-based convolutional neural networks (Mask R-CNN)(with video).

The artificial intelligence (AI)-assisted endoscopic detection of early gastric cancer (EGC) has been preliminarily developed. The currently used algorithms still exhibit limitations of large calculation and low-precision expression. The present study aimed to develop an endoscopic automatic detection system in EGC based on a mask region-based convolutional neural network (Mask R-CNN) and to evaluate the performance in controlled trials. For this purpose, a total of 4,471 white light images (WLIs) and 2,662 narrow band images (NBIs) of EGC were obtained for training and testing. In total, 10 of the WLIs (videos) were obtained prospectively to examine the performance of the RCNN system. Furthermore, 400 WLIs were randomly selected for comparison between the Mask R-CNN system and doctors. The evaluation criteria included accuracy, sensitivity, specificity, positive predictive value and negative predictive value. The results revealed that there were no significant differences between the pathological diagnosis with the Mask R-CNN system in the WLI test (χ2 = 0.189, P=0.664; accuracy, 90.25%; sensitivity, 91.06%; specificity, 89.01%) and in the NBI test (χ2 = 0.063, P=0.802; accuracy, 95.12%; sensitivity, 97.59%). Among 10 WLI real-time videos, the speed of the test videos was up to 35 frames/sec, with an accuracy of 90.27%. In a controlled experiment of 400 WLIs, the sensitivity of the Mask R-CNN system was significantly higher than that of experts (χ2 = 7.059, P=0.000; 93.00% VS 80.20%), and the specificity was higher than that of the juniors (χ2 = 9.955, P=0.000, 82.67% VS 71.87%), and the overall accuracy rate was higher than that of the seniors (χ2 = 7.009, P=0.000, 85.25% VS 78.00%). On the whole, the present study demonstrates that the Mask R-CNN system exhibited an excellent performance status for the detection of EGC, particularly for the real-time analysis of WLIs. It may thus be effectively applied to clinical settings.

Efficient Initial Eradication of Large Esophageal Varices by Balloon-compression Endoscopic Injection Sclerotherapy.

BACKGROUND: The management of large esophageal varices (EVs) remains challenging because of the difficulty of endoscopic variceal ligation and fatal post-endoscopic variceal ligation bleeding ulcers. The current study evaluated the efficacy and safety of balloon-compression endoscopic injection sclerotherapy (bc-EIS) in the treatment of large EVs. MATERIALS AND METHODS: This retrospective study included 105 patients with cirrhosis exhibiting large EVs (64 in the bc-EIS group and 41 in the EIS group). Primary outcomes included the initial rate of variceal eradication and intraoperative bleeding signs. Secondary outcomes included incidences of rebleeding, mortality, complications, and optimal time of balloon-compression (bc). RESULTS: The initial rate of variceal eradication in the bc-EIS group was significantly higher than that in the EIS group (46.9 vs. 24.4%; P =0.021). The incidence of intraoperative bleeding, which was represented as oozing and spurting, in the bc-EIS group was markedly lower than that in the EIS group (43.8 vs. 61.0% and 9.4 vs. 39.0%, respectively; P =0.043). Patients in the bc-EIS group showed a significantly lower incidence of rebleeding (0.0 vs. 17.1%; P =0.001). However, no significant difference in mortality rate was observed between different groups. Chest pain or discomfort tended to be more common in the EIS group than in the bc-EIS group (58.5 vs. 17.2%; P =0.001). The cut-off value of 11.5-minutes appeared to have a maximum combined sensitivity and specificity of 80.0% and 58.8%, respectively. The area under the curve was 0.708 (95% confidence interval =0.576-0.839; P =0.004). CONCLUSION: bc-EIS could achieve a higher variceal eradication rate and milder intraoperative bleeding signs in large EVs. Furthermore, 11.5-minutes appeared to be the optimal compression time in bc-EIS.

Novel balloon compression-assisted endoscopic injection sclerotherapy and endoscopic variceal ligation in the treatment of esophageal varices: a prospective randomized study.

BACKGROUND: Herein, our group designed a novel technology, termed balloon compression-assisted endoscopic injection sclerotherapy (bc-EIS), which was applied to improve the efficiency of eradicating esophageal varices (EVs). The present study aimed to compare the rate of eradication and efficacy between bc-EIS and endoscopic variceal ligation (EVL) in the management of EVs. METHODS: Ninety-five patients with esophageal variceal bleeding (EVB) were randomly assigned to receive bc-EIS or ligation alone. Additional treatment sessions were held 1 month later and then at 3-month intervals until eradication of the varices was achieved. Endoscopic follow-up examinations were carried out at 6-month intervals in the absence of recurrence or immediately if there was any recurrent bleeding. RESULTS: The mean physical injection points per session were 2.89 ± 0.79, and the mean volume of lauromacrogol used per session was 17.74 ± 7.09 ml in the bc-EIS group. The mean band per session was 6.13 ± 0.86. The rate of eradication after one to three rounds of bc-EIS was obviously higher than that of the EVL group (89.36%, 97.87%, and 100% vs. 37.5%, 43.75%, and 47.92%, respectively). Retrosternal pain or discomfort in the bc-EIS group was slightly lower than that in the EVL group (23.4%, 11/47 vs. 31.25%, 15/48). Two and five patients showed mild abdominal bloating and distension between the bc-EIS and EVL groups, respectively (2/47, 4.26% vs. 5/48, 10.42% P > 0.05). Nausea and vomiting were reported in one patient (1/47, 2.13%) in the bc-EIS group and three patients (3/48, 6.25%) in the EVL group. However, there were no statistically significant differences between the two groups (P > 0.05). No fatal or severe complications, such as esophageal perforation, esophageal stricture or ectopic embolism, were observed. CONCLUSION: The bc-EIS method was effective in eradicating EVs and was accompanied by fewer complications.

Comparison of transjugular intrahepatic portosystemic with endoscopic treatment plus anticoagulation for esophageal variceal bleeding and portal vein thrombosis in liver cirrhosis.

BACKGROUND AND AIM: The optimal management of esophageal variceal bleeding (EVB) and portal vein thrombosis (PVT) in liver cirrhosis has not been well-established. The aim of the present study was to compare the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) and endoscopic treatment (ET) plus anticoagulation in cirrhotic patients with EVB and PVT. PATIENTS AND METHODS: A total of 66 cirrhotic patients with PVT and EVB (31 in the TIPS group and 35 in the ET plus anticoagulation group) were evaluated retrospectively between January 2016 and January 2022. RESULTS: During the follow-up period, 85.5% of patients in the TIPS group achieved complete recanalization of the portal vein, as compared with 19.6% in the ET plus anticoagulation group (p < .001). The cumulative 5-year rate of variceal rebleeding in the TIPS group was significantly lower than that in the ET plus anticoagulation group (31.0 vs. 50.1%; p = .017). The TIPS group exhibited a significantly higher incidence of overt hepatic encephalopathy (HE) than the ET plus anticoagulation group (25.8 vs. 5.7%; p = .037). No difference in the 5-year survival rate (74.1 vs. 85.7%; p = .692) and probability of other complications was observed between the two groups. CONCLUSION: TIPS was superior to ET plus anticoagulation in preventing variceal rebleeding and achieving recanalization of PVT but increased the incidence of overt HE without improving the survival rate.

Efficacy of Endoscopic Intervention plus Growth Inhibitor and Patient Self-Management in the Treatment of Esophagogastric Variceal Bleeding in Cirrhosis.

Objective: To assess the efficacy of endoscopic intervention plus growth inhibitor and patient self-management in the treatment of esophagogastric variceal bleeding. Methods: Between January 2019 and December 2021, 60 patients with esophagogastric variceal bleeding treated in our hospital were assessed for eligibility and randomly recruited. They were concurrently and randomly assigned at a ratio of 1 : 1 to receive either endoscopic intervention plus growth inhibitor (control group) or endoscopic intervention plus growth inhibitor and patient self-management (observation group). The endpoint is clinical efficacy. Results: All eligible patients showed a similar time of hemostasis, success rate of hemostasis, rebleeding rate, and disappearance rate of varicose veins (P > 0.05). Endoscopic intervention plus growth inhibitor and patient self-management were associated with a lower incidence of complication (6.67%, including 1 (3.34%) case of ulcer and 1 (3.34%) case of fever) than endoscopic intervention plus growth inhibitor (26.67%, including 3 (10.00%) cases of ulcer, 2 (6.67%) cases of retrosternal pain, and 3 (10.00%) cases of fever) (P < 0.05). Patients in the observation group had significantly higher life satisfaction scores (25.17 ± 4.28 and 23.68 ± 5.17) than those in the control group (22.13 ± 2.24 and 18.12 ± 3.28) (P < 0.05). A decrease in life satisfaction scores was observed at 6 months after treatment, and the patients given patient self-management showed a higher satisfaction (P < 0.05). Conclusion: Endoscopic intervention plus growth inhibitor and patient self-management yielded remarkable clinical efficacy in the treatment of esophagogastric variceal bleeding as it reduces the incidence of complication and enhances the life satisfaction of patients, and so it is worthy of clinical promotion.
