Comparative efficacy of early TIPS, Non-early TIPS, and Standard treatment in patients with cirrhosis and acute variceal bleeding: a network meta-analysis

BACKGROUND

Cirrhosis is a chronic disease characterized by chronic liver inflammation and diffuse fibrosis. A combination of vasoactive drugs, preventive antibiotics, and endoscopy is the recommended standard treatment for patients with acute variceal bleeding; however, this has been challenged. We compared the effects of early transjugular intrahepatic portosystemic shunt (TIPS), non-early TIPS, and standard treatment in patients with cirrhosis and acute variceal bleeding.

MATERIALS AND METHODS

The present network meta-analysis was conducted in accordance with the criteria outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Assessing the methodological quality of systematic reviews guidelines. The review has been registered with the International Prospective Register of Systematic Reviews. The PubMed, Embase, Cochrane Library, ClinicalTrials.gov, and World Health Organization-approved trial registry databases were searched for randomized controlled trials (RCTs) evaluating early TIPS, non-early TIPS, and standard treatment in patients with cirrhosis and acute variceal bleeding.

RESULTS

Twenty-four RCTs (1894 patients) were included in the review. Compared with standard treatment, early TIPS [odds ratio (OR), 0.53; 95% credible interval (Cr), 0.30-0.94; surface under the cumulative ranking curve (SUCRA), 98.3] had a lower risk of all-cause mortality (moderate-to-high-quality evidence), and early TIPS (OR, 0.19; 95% CrI, 0.11-0.28; SUCRA, 98.2) and non-early TIPS (OR, 0.30; 95% CrI, 0.23-0.42; SUCRA, 1.8) were associated with a lower risk of rebleeding (moderate-to-high-quality evidence). Early TIPS was not associated with a reduced risk of hepatic encephalopathy, and non-early TIPS (OR, 2.78; 95% CrI, 1.89-4.23, SUCRA, 0) was associated with an increased incidence of hepatic encephalopathy (moderate-to-high-quality evidence). There was no difference in the incidence of new or worsening ascites (moderate-to-high-quality evidence) among the three interventions.

CONCLUSION

Based on the moderate-to-high quality evidence presented in this study, early TIPS placement was associated with reduced all-cause mortality [with a median follow-up of 1.9 years (25th-75th percentile range 1.9-2.3 years)] and rebleeding compared to standard treatment and non-early TIPS. Although early TIPS and standard treatment had a comparable incidence of hepatic encephalopathy, early TIPS showed superiority over non-early TIPS in this aspect. Recent studies have also shown promising results in controlling TIPS-related hepatic encephalopathy. However, it is important to consider individual patient characteristics and weigh the potential benefits against the risks associated with early TIPS. Therefore, we recommend that clinicians carefully evaluate the patient's condition, considering factors such as severity of variceal bleeding, underlying liver disease, and overall clinical status, before making a treatment decision. Further well-designed RCTs comparing early TIPS with non-early TIPS are needed to validate these findings and provide more definitive guidance.

Clinical outcomes of endoscopic submucosal dissection for superficial esophageal neoplasia in close proximity to esophageal varices: a multicenter international experience

BACKGROUND : There are limited data on the feasibility of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasia (SEN) located at or adjacent to esophageal varices. We aimed to evaluate the outcomes of ESD in these patients.

METHODS

 This multicenter retrospective study included cirrhotic patients with a history of esophageal varices with SEN located at or adjacent to the esophageal varices who underwent ESD.

RESULTS

 23 patients with SEN (median lesion size 30 mm; 16 squamous cell neoplasia and seven Barrett's esophagus-related neoplasia) were included. The majority were Child-Pugh B (57 %) and had small esophageal varices (87 %). En bloc, R0, and curative resections were achieved in 22 (96 %), 21 (91 %), and 19 (83 %) of patients, respectively. Severe intraprocedural bleeding (n = 1) and delayed bleeding (n = 1) were successfully treated endoscopically. No delayed perforation, hepatic decompensation, or deaths were observed. During a median (interquartile range) follow-up of 36 (22-55) months, one case of local recurrence occurred after noncurative resection.

CONCLUSION

 ESD is feasible and effective for SEN located at or adjacent to esophageal varices in cirrhotic patients. Albeit, the majority of the esophageal varices in our study were small in size, when expertise is available, ESD should be considered as a viable option for such patients.

Effectiveness of antibiotic prophylaxis for acute esophageal variceal bleeding in patients with band ligation: A large observational study

BACKGROUND

Esophageal variceal bleeding is a severe complication associated with liver cirrhosis and typically necessitates endoscopic hemostasis. The current standard treatment is endoscopic variceal ligation (EVL), and Western guidelines recommend antibiotic prophylaxis following hemostasis. However, given the improvements in prognosis for variceal bleeding due to advancements in the management of bleeding and treatments of liver cirrhosis and the global concerns regarding the emergence of multidrug-resistant bacteria, there is a need to reassess the use of routine antibiotic prophylaxis after hemostasis.

AIM

To evaluate the effectiveness of antibiotic prophylaxis in patients treated for EVL.

METHODS

We conducted a 13-year observational study using the Tokushukai medical database across 46 hospitals. Patients were divided into the prophylaxis group (received antibiotics on admission or the next day) and the non-prophylaxis group (did not receive antibiotics within one day of admission). The primary outcome was composed of 6-wk mortality, 4-wk rebleeding, and 4-wk spontaneous bacterial peritonitis (SBP). The secondary outcomes were each individual result and in-hospital mortality. A logistic regression with inverse probability of treatment weighting was used. A subgroup analysis was conducted based on the Child-Pugh classification to determine its influence on the primary outcome measures, while sensitivity analyses for antibiotic type and duration were also performed.

RESULTS

Among 980 patients, 790 were included (prophylaxis: 232, non-prophylaxis: 558). Most patients were males under the age of 65 years with a median Child-Pugh score of 8. The composite primary outcomes occurred in 11.2% of patients in the prophylaxis group and 9.5% in the non-prophylaxis group. No significant differences in outcomes were observed between the groups (adjusted odds ratio, 1.11; 95% confidence interval, 0.61-1.99; P = 0.74). Individual outcomes such as 6-wk mortality, 4-wk rebleeding, 4-wk onset of SBP, and in-hospital mortality were not significantly different between the groups. The primary outcome did not differ between the Child-Pugh subgroups. Similar results were observed in the sensitivity analyses.

CONCLUSION

No significant benefit to antibiotic prophylaxis for esophageal variceal bleeding treated with EVL was detected in this study. Global reassessment of routine antibiotic prophylaxis is imperative.

Influence of subcutaneous adipose tissue index on prognosis in cirrhotic patients following endoscopic therapy: a retrospective cohort study

BACKGROUND

The relation of adipose tissue depletion with prognostic outcome of variceal bleeding among cirrhotic patients is still inconclusive. The present work explored whether adipose tissue, which was measured based on computed tomography (CT), was valuable for analyzing rebleeding and mortality among patients with variceal bleeding who had undergone endoscopic therapy.

METHODS

The study encompassed cirrhotic patients who underwent endoscopic therapy to prevent variceal rebleeding between January 2016 and October 2022. The L3-level CT images were obtained. Besides, impacts of subcutaneous adipose tissue index (SATI), visceral adipose tissue index (VATI), as well as total adipose tissue index (TATI) on rebleeding and mortality among cirrhotic patients following endoscopic therapy were examined.

RESULTS

In this work, our median follow-up period was 31 months. Among those adipose tissue indexes, only SATI exhibited an independent relation to higher rebleeding (HR 0.981, 95% CI, 0.971-0.991, p < 0.001) and mortality (HR 0.965, 95% CI, 0.944-0.986, p = 0.001) risks. Upon multivariate Cox regression, low SATI (male < 30.15 cm2/m2, female < 39.82 cm2/m2) was independently linked to higher rebleeding risk (HR 2.511, 95% CI, 1.604-3.932, p < 0.001) and increased mortality risk (HR 3.422, 95% CI, 1.489-7.864, p = 0.004) after adjusting for other predictors. Furthermore, subgroups were created based on using nonselective β-blockers (NSBBs), demonstrating that quantitatively assessing SATI exerts a vital role in evaluating rebleeding incidence in patients with or without NSBB therapy.

CONCLUSION

This study underscores the potential of quantifying SATI as a means for achieving a more accurate risk classification for individual patients and identifying patients that can gain more benefits from nutritional intervention.

Endohepatology: The endoscopic armamentarium in the hand of the hepatologist

ABSTRACT

Recent advances in the field of hepatology include new and effective treatments for viral hepatitis. Further effort is now being directed to other disease entities, such as non-alcoholic fatty liver disease, with an increased need for assessment of liver function and histology. In fact, with the evolving nomenclature of fat-associated liver disease and the emergence of the term "metabolic-associated fatty liver disease" (MAFLD), new diagnostic challenges have emerged as patients with histologic absence of steatosis can still be classified under the umbrella of MAFLD. Currently, there is a growing number of endoscopic procedures that are pertinent to patients with liver disease. Indeed, interventional radiologists mostly perform interventional procedures such as percutaneous and intravascular procedures, whereas endoscopists focus on screening for and treatment of esophageal and gastric varices. EUS has proven to be of value in many areas within the realm of hepatology, including liver biopsy, assessment of liver fibrosis, measurement of portal pressure, managing variceal bleeding, and EUS-guided paracentesis. In this review article, we will address the endoscopic applications that are used to manage patients with chronic liver disease.

Predicting survival in patients with 'non-high-risk' acute variceal bleeding receiving β-blockers+ligation to prevent re-bleeding

BACKGROUND & AIMS

Pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) is the treatment of choice for high-risk acute variceal bleeding (AVB; i.e., Child-Turcotte-Pugh [CTP] B8-9+active bleeding/C10-13). Nevertheless, some 'non-high-risk' patients have poor outcomes despite the combination of non-selective beta-blockers and endoscopic variceal ligation for secondary prophylaxis. We investigated prognostic factors for re-bleeding and mortality in 'non-high-risk' AVB to identify subgroups who may benefit from more potent treatments (i.e., TIPS) to prevent further decompensation and mortality.

METHODS

A total of 2,225 adults with cirrhosis and variceal bleeding were prospectively recruited at 34 centres between 2011-2015; for the purpose of this study, case definitions and information on prognostic indicators at index AVB and on day 5 were further refined in low-risk patients, of whom 581 (without failure to control bleeding or contraindications to TIPS) who were managed by non-selective beta-blockers/endoscopic variceal ligation, were finally included. Patients were followed for 1 year.

RESULTS

Overall, 90 patients (15%) re-bled and 70 (12%) patients died during follow-up. Using clinical routine data, no meaningful predictors of re-bleeding were identified. However, re-bleeding (included as a time-dependent co-variable) increased mortality, even after accounting for differences in patient characteristics (adjusted cause-specific hazard ratio: 2.57; 95% CI 1.43-4.62; p = 0.002). A nomogram including CTP, creatinine, and sodium measured at baseline accurately (concordance: 0.752) stratified the risk of death.

CONCLUSION

The majority of 'non-high-risk' patients with AVB have an excellent prognosis, if treated according to current recommendations. However, about one-fifth of patients, i.e. those with CTP ≥8 and/or high creatinine levels or hyponatremia, have a considerable risk of death within 1 year of the index bleed. Future clinical trials should investigate whether elective TIPS placement reduces mortality in these patients.

IMPACT AND IMPLICATIONS

Pre-emptive transjugular intrahepatic portosystemic shunt placement improves outcomes in high-risk acute variceal bleeding; nevertheless, some 'non-high-risk' patients have poor outcomes despite the combination of non-selective beta-blockers and endoscopic variceal ligation. This is the first large-scale study investigating prognostic factors for re-bleeding and mortality in 'non-high-risk' acute variceal bleeding. While no clinically meaningful predictors were identified for re-bleeding, we developed a nomogram integrating baseline Child-Turcotte-Pugh score, creatinine, and sodium to stratify mortality risk. Our study paves the way for future clinical trials evaluating whether elective transjugular intrahepatic portosystemic shunt placement improves outcomes in presumably 'non-high-risk' patients who are identified as being at increased risk of death.

Factors influencing in-hospital mortality for salvage percutaneous transjugular intrahepatic portosystemic shunting in cirrhotic patients with recalcitrant variceal bleeding after failed endoscopic intervention

BACKGROUND

Endoscopic therapy is the first-line treatment of choice for control of acute variceal bleeding (AVB). In high-risk patients with persistent AVB despite pharmacological treatment and endoscopic intervention, percutaneous transjugular intrahepatic portosystemic shunting (TIPS) provides a minimally invasive salvage method to reduce portal pressure and control bleeding.

OBJECTIVES

To evaluate factors influencing in-hospital mortality after salvage TIPS (sTIPS) in patients with exsanguinating variceal bleeding despite medical treatment and endoscopic intervention.

METHODS

Clinical and laboratory data were analysed in all patients treated with sTIPS following failed endoscopic therapy for AVB between August 1991 and November 2020. Factors associated with and predictors of death were determined using bivariate analysis and univariate logistic regression analysis.

RESULTS

Thirty-four patients (29 men, 5 women), mean age 52 years (range 31 - 80), received sTIPS for uncontrolled (n=11) or refractory (n=23) AVB. The causes of portal hypertension were alcohol-related (n=24) and non-alcohol-related cirrhosis. Salvage TIPS controlled bleeding in 32 patients, with recurrence in 1. Ten patients died in hospital (mean 4.8 days, range 1 - 10) of liver failure (n=4), multiorgan failure (n=3), alcoholic cardiomyopathy (n=2) and uncontrolled gastric variceal bleeding (n=1). On bivariate analysis, factors associated with death were Child-Pugh (C-P) score ≥10 (p=0.006), sodium Model for End-stage Liver Disease (MELD-Na) score ≥22 (p<0.001), ≥8 units of blood transfused (p<0.001), Sengstaken-Blakemore balloon tube placement (p<0.001), endotracheal intubation (p<0.001), inotropic support (p<0.001) and endoscopically uncontrolled bleeding (p<0.001). Univariate logistic regression analysis showed that the most significant predictors of mortality were inotrope dependency (odds ratio (OR) 134; p<0.001), endotracheal intubation (OR 99; p<0.001), endoscopically uncontrolled bleeding (OR 28; p=0.001), grade 3 ascites (OR 20.9; p=0.012) and C-P grade C (OR 8.8; p=0.011).

CONCLUSION

Salvage TIPS controlled variceal bleeding in 94% of patients after failed endoscopic therapy with 29% in-hospital mortality. The most significant predictors of mortality were C-P grade C, grade 3 ascites, inotrope requirement, endotracheal intubation and endoscopically uncontrolled bleeding.

Life-threatening variceal bleeding after liver transplantation and extensive portal vein thrombosis: Desperate times call for desperate measures

BACKGROUND

The management of complex, intra- and extrahepatic portal vein thrombosis (PVT) after liver transplantation (LT) is challenging. Although most of the patients remain asymptomatic or oligosymptomatic in the chronic setting, some of them may develop severe portal hypertension and related complications, notably gastrointestinal (GI) bleeding. In the emergency scenario, clinical and endoscopic treatments as well as intensive support constitute the bases of conservative management, while more definitive treatment options such as surgical shunting and retransplantation are related to high morbidity rates. Transjugular intrahepatic portosystemic shunt (TIPS) was largely considered of limited role due to technical difficulties arising from extensive PVT. Recently, however, new minimally invasive image-guided techniques emerged, allowing portal vein recanalization and TIPS creation simultaneously (TIPS-PVR), even in complex PVT pretransplant patients.

METHODS

Herein, we describe a novel indication for TIPS-PVR in a post-LT adolescent presenting with life-threatening, refractory GI bleeding.

RESULTS

The patient presented with complete resolution of the hemorrhagic condition after the procedure, with no deterioration of hepatic function or hepatic encephalopathy. Follow-up Doppler ultrasound after TIPS-PVR showed normal hepatopetal venous flow within the stents, and no evidence of complications, including intraperitoneal or peri splenic bleeding.

CONCLUSIONS

This report describes the feasibility of TIPS-PVR in the post-LT scenario complicated by extensive PVT. In this case, a complete resolution of the life-threatening GI bleeding was achieved, with no major complications. Other patients with complex chronic PVT might benefit from the use of the described technique, but further studies are required to determine the correct timing and indications of the procedure, eventually before the occurrence of life-threatening complications.

Esophageal stent placement for endoscopic treatment failure

Up until approximately 10 years ago, the treatment for acute refractory esophageal variceal bleeding was balloon tamponading. Esophageal fully covered self-expanding stents are considered as effective as balloons and also much safer. They are kept in situ for longer periods, what eases the access to more definitive treatments with a low complication rate. We present 6 cases of patients with cirrhosis and massive bleeding due to esophageal varices refractory to conventional treatment, successfully treated with an esophageal fully covered self-expanding stent. There were no major complications, achieving an effective bleeding control in all cases.

Surgical Treatment of Portal Hypertension in Children

Introduction: Portal hypertension is a syndrome characterized by increased pressure in the portal vein system and can be caused by impaired blood flow in the portal vein, hepatic veins, or inferior vena cava. The main complications of this condition are bleeding from varicose veins of the esophagus (in our study in 100% of patients), splenomegaly with hypersplenism (in our study in 98% of patients), ascites (in our study in 1 patient). The main goal of treating portal hypertension is to prevent bleeding from esophageal varices. However, today the goal of surgical treatment of portal hypertension in children is not only to prevent the development of bleeding but also the possible restoration of intrahepatic blood flow. Materials and Methods: A retrospective analysis of the results of treatment of portal hypertension in 75 children (41 boys, 34 girls) operated in our Center for the period from 2019 to 2022 was carried out. The mean age of the patients was 7 ± 1 years. Sixty-nine patients had an extrahepatic form of portal hypertension, and 6 patients had an intrahepatic form (liver fibrosis). In 14 patients (18.6%), the operation was repeated (a vascular shunt was previously applied in another hospital; 4 children were operated on repeatedly). Results: A good result was obtained in all children, and the risk of bleeding from varicose veins of the esophagus was eliminated. Vascular bypass surgery was performed in all cases: mesoportal bypass in 17 (22.7%) patients, splenorenal bypass in 37 (49.3%) patients, mesocaval bypass in 21 (28%) patients. In 10 (13%) cases, repeated bypass surgery was required due to dysfunction or thrombosis of the previously performed bypass. In 14 (18.6%) patients with mesoportal shunts, blood flow in the liver was completely restored. Conclusions: The main method of surgical treatment of portal hypertension today is portosystemic bypass surgery, which effectively prevents bleeding from varicose veins of the esophagus. Mesoportal shunting is a definitive treatment for extrahepatic portal hypertension that restores portal perfusion of the liver.

Predicting the risk of early bleeding following endoscopic variceal ligation in cirrhotic patients with computed tomography

BACKGROUND

Life-threatening bleeding following endoscopic variceal ligation (EVL) in patients with cirrhosis rarely can occur. The present study aimed to evaluate the performance of computed tomography (CT) in predicting the risk of early bleeding following EVL in cirrhotic patients.

METHODS

We retrospectively investigated 285 cirrhotic patients who had undergone EVL. EVL was performed for prophylaxis or acute variceal bleeding. The patients were classified into 2 groups: early bleeding (< 14 days after EVL) and non-early bleeding. We compared baseline characteristics including CT findings between the patient groups.

RESULTS

Among the 285 patients who underwent EVL treatment, 19 patients (6.7%) experienced early bleeding. On average, these bleeding occurred 9.3 ± 3.5 days after the EVL, with a range of 3 to 13 days. Patients who experience early bleeding had a higher six-week bleeding-related mortality rate compared to those in the non-early bleeding group (31.6% vs. 10.2%; p = 0.014). There was a correlation between the grade of esophageal varix observed during endoscopy and the diameter of esophageal varix observed on CT (p < 0.001). The diameter of esophageal varix on CT was identified as the only significant predictive factor for early bleeding (p = 0.005).

CONCLUSION

A larger esophageal varix diameter observed on CT is associated with an increased risk of early bleeding after EVL treatment. Early identification of this high-risk group can provide a change of treatment strategies to improve patient outcomes.

Liver Transplantation in a Woman with Mahvash Disease

Mahvash disease is an exceedingly rare genetic disorder of glucagon signaling characterized by hyperglucagonemia, hyperaminoacidemia, and pancreatic α-cell hyperplasia. Although there is no known definitive treatment, octreotide has been used to decrease systemic glucagon levels. We describe a woman who presented to our medical center after three episodes of small-volume hematemesis. She was found to have hyperglucagonemia and pancreatic hypertrophy with genetically confirmed Mahvash disease and also had evidence of portal hypertension (recurrent portosystemic encephalopathy and variceal hemorrhage) in the absence of cirrhosis. These findings established a diagnosis of portosinusoidal vascular disease, a presinusoidal type of portal hypertension previously known as noncirrhotic portal hypertension. Liver transplantation was followed by normalization of serum glucagon and ammonia levels, reversal of pancreatic hypertrophy, and resolution of recurrent encephalopathy and bleeding varices.

The decreased risk of hepatocellular carcinoma in hepatitis B virus-related cirrhotic portal hypertension patients after laparoscopic splenectomy and azygoportal disconnection

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.

Impressive recompensation in transjugular intrahepatic portosystemic shunt-treated individuals with complications of decompensated cirrhosis based on Baveno VII criteria

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is the standard second-line treatment option for individuals with complications of decompensated cirrhosis, such as variceal bleeding and refractory ascites.

AIM

To investigate whether recompensation existed in TIPS-treated patients with decompensated cirrhosis according to Baveno VII criteria.

METHODS

This retrospective analysis was performed on 64 patients who received TIPS for variceal bleeding or refractory ascites. The definition of recompensation referred to Baveno VII criteria and previous study. Clinical events, laboratory tests, and radiological examinations were regularly conducted during a preset follow-up period. The recompensation ratio in this cohort was calculated. Beyond that, univariate and multivariate regression models were conducted to identify the predictors of recompensation.

RESULTS

Of the 64 patients with a 12-mo follow-up, 20 (31%) achieved recompensation. Age [odds ratio (OR): 1.124; 95% confidence interval (CI): 1.034-1.222] and post-TIPS portal pressure gradient < 12 mmHg (OR: 0.119; 95%CI: 0.024-0.584) were identified as independent predictors of recompensation in patients with decompensated cirrhosis after TIPS.

CONCLUSION

The present study demonstrated that nearly one-third of the TIPS-treated patients achieved recompensation within this cohort. According to our findings, recompensation is more likely to be achieved in younger patients. In addition, postoperative portal pressure gradient reduction below 12 mmHg contributes to the occurrence of recompensation.

Comparison of Spleen-Preservation Versus Splenectomy in Minimally Invasive Distal Pancreatectomy

BACKGROUND

Spleen-preservation during minimally invasive distal pancreatectomy (MIDP) can be technically challenging and remains controversial. Our primary aim was to compare MIDP and splenectomy with spleen-preserving MIDP. Secondarily, we compared two spleen-preserving techniques.

METHODS

Adults undergoing MIDP (2007-2021) were retrospectively included in this single-center study. Intraoperative and postoperative outcomes between spleen-preservation and splenectomy and between the two spleen-preserving techniques were compared using the Mann-Whitney U test for continuous data, and Fisher's exact test for categorical data.

RESULTS

Of the 293 patients who underwent MIDP, preservation of the spleen was intended in 208 (71%) patients. Spleen-preservation was achieved in 174 patients (84%) via the Warshaw technique (130; 75%) or vessel-preservation (44; 25%). The spleen-preserving group had shorter length of stay (3 vs 4 days, p < 0.01), fewer conversions to open (1 vs 12, p < 0.01) and less blood loss (p < 0.01) compared to the splenectomy group. Operative (OR) times were comparable (229 vs 214 min, p = 0.67). Except for the operative time, which was longer for the Warshaw technique (245 vs 183 min, p = 0.01), no other differences between the two spleen-preserving techniques were found. At a median follow-up of 43 (IQR 18-79) months after spleen-preservation, only 2 (1.1%) patients had required splenectomy (1 partial splenectomy for infarct/abscess after Warshaw, 1 for variceal bleeding after vessel-preserving).

CONCLUSIONS

Spleen-preservation is not associated with increased risk of blood loss, longer hospital stay, conversion, nor lengthy OR times. Late splenectomy is very rarely required. Given the immune consequences of splenectomy, spleen-preservation should be strongly considered in MIDP.

Endoscopic Ultrasound-Guided Transgastric Shunt Obliteration for Recurrent Hepatic Encephalopathy

INTRODUCTION

Occlusion of spontaneous portosystemic shunts (SPSSs) in patients with cirrhosis may be required in recurrent or refractory hepatic encephalopathy. We describe a novel method for occlusion of SPSS using endoscopic ultrasound (EUS).

METHODS

EUS-guided transgastric shunt obliteration was performed by injecting glue and coils directly into SPSS.

RESULTS

EUS-guided transgastric shunt obliteration was performed for 7 patients in 9 sessions. Complete cessation of Doppler flow was achieved in 6/7 cases. Adequate clinical response was observed in 6/7 patients. No procedure-related severe adverse events were seen.

DISCUSSION

This novel technique is a potentially effective and efficient method for shunt obliteration.

Outcomes of Transjugular Intrahepatic Portosystemic Shunt and Gastric Coronary Vein Embolization for Variceal Bleeding in Cirrhotic Portal Hypertension

Purpose: To evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) combined with gastric coronary vein embolization (GCVE) for cirrhotic portal hypertensive variceal bleeding and compare outcomes of first-line with second-line treatment, coil with glue, and single-covered with double stents.Methods: Fifteen patients received TIPS plus GCVE as the first-line treatment for secondary prophylaxis of variceal bleeding, and 45 received it as second-line treatment. Preoperative and postoperative quantitative variables were compared using a paired t test. The incidence of survival rate, re-bleeding, hepatic encephalopathy, and shunt dysfunction were analyzed using the Kaplan-Meier method.Results: The portal venous pressure was significantly decreased from 39.0 ± 5.0 mm Hg to 22.5 ± 4.4 mm Hg (P≤0.001) after TIPS treatment. After 1, 3, 6, 12, 18, and 24 months re-bleeding rates were 1.6%, 3.3%, 6.6%, 13.3%, 0%, and 0%, respectively. Shunt dysfunction rates were 5%, 0%, 10%, 16.6%, 1.6%, and 5%, respectively. Hepatic encephalopathy rates were 3.3%, 1.6%, 3.3%, 6.6%, 0%, and 0%, respectively. And survival rates were 100%, 100%, 100%, 96.6%, 93.3%, and 88.3% respectively. In comparative analysis, statistically significant differences were seen in re-bleeding between the first-line and second-line treatment groups (26.6% vs 24.4%, log-rank P=0.012), and survival rates between single-covered and double stent (3.7% vs 16.1%, log-rang (P=0.043).Conclusion: The results suggest that TIPS combined with GCVE is effective and safer in the treatment of cirrhotic portal hypertensive variceal bleeding. The use of TIP plus GCVE as first-line treatment, may be preferable for high-risk re-bleeding, and more than 25 mm Hg portal venous pressure with repeated variceal bleeding. However, the sample size was small. Therefore, large, randomized, controlled, multidisciplinary center studies are needed for further evaluation.

Outcome of Children with Transjugular Intrahepatic Portosystemic Shunt: A Meta-Analysis of Individual Patient Data

PURPOSE

The purpose of the study was to investigate outcome after pediatric transjugular intrahepatic portosystemic shunt (TIPS) with respect to survival MATERIAL AND METHODS: After searching for studies on TIPS in children in Ovid, Medline, Embase, Scopus and Cochrane published between 2000 and 2022, individual patient data were retrieved from five retrospective cohorts. Overall survival (OS) and transplant-free survival (TFS) were calculated using Kaplan-Meier analysis and log-rank test and compared to the indication (ascites vs. variceal bleeding) as well as to the level of obstruction (pre-hepatic vs. hepatic vs. post-hepatic). Additionally, TIPS patency was analyzed.

RESULTS

n = 135 pediatric patients were included in the final analysis. Indication for pediatric TIPS creation was heterogeneous among the included studies. TIPS patency decreased from 6 to 24 months, subsequent pediatric liver transplantation was performed in 22/135 (16.3%) of cases. The presence of ascites was related with poorer TFS (HR 2.3, p = 0.023), while variceal bleeding was not associated with impaired survival. Analysis of the level of obstruction (pre-hepatic, hepatic and post-hepatic) failed to prove significantly reduced OS for post-hepatic obstruction (HR 3.2, p = 0.092) and TFS (HR 1.3, p = 0.057). There was no difference in OS and TFS according to age at time of TIPS placement.

CONCLUSIONS

The presence of ascites associates with impaired survival after TIPS in children, with no differences in survival according to the age of the child. Interventional shunt procedures can be considered feasible for all ages.

Risk factors analysis of endoscopy and TIPS in the treatment of secondary esophagogastric varicose bleeding with cirrhosis

Objective

To analyse the risk factors of secondary hemorrhage and survival rate in cirrhotic patients with esophagogastric variceal rupture and to compare the efficacy and safety of endoscopic hemostasis and TIPS (transjugular intrahepatic portosystemic shunt).

Methods

A total of 120 patients with secondary bleeding after endoscopic treatment of esophagogastric varicose bleeding with cirrhosis in our hospital during the past 3 years were retrospectively analysed. There were 65 males and 55 females, ranging in age from 49 to 74 years old, with an average of (59.5 ± 8.4) years old. The etiology, degree of varicose veins, bleeding location, hemostasis method, Infection, ascites, portal vein thrombosis or cancer thrombus, albumin, platelets, prothrombin activity, Child Pugh (Child-Pugh classification is a diagnostic criterion for liver reserve function) grade were compared in each group. The risk factors of treatment failure and analyse the survival time was analysed.

Results

There were statistically significant differences in varicosis degree, infection, ascites, portal vein thrombosis or cancer thrombus, child Pugh grade, albumin and prothrombin activity between the failed Endoscopy group and the successful hemostasis group (P< 0.05). There were statistically significant differences in child Pugh grade, albumin and prothrombin activity between the failed TIPS treatment group and successful hemostasis group (P< 0.05). There was no significant difference in 1-year survival between the endoscopy group and the TIPS group.

Conclusion

Severe varicose veins, infection, ascites, portal vein thrombosis or cancer thrombus, child pugh classification, albumin, and prothrombin activity were the major risk factors for failed secondary endoscopic therapy, child Pugh classification, albumin and prothrombin activity were the main risk factors for failure TIPS treatment. There is no significant difference in long-term survival between the two methods.
