Transjugular intrahepatic portosystemic shunt versus open splenectomy and esophagogastric devascularization for portal hypertension with recurrent variceal bleeding

Prognosis of LSPD versus TIPS for the treatment of esophagogastric variceal bleeding in cirrhosis

BACKGROUND

This study aimed to compare postoperative complications in patients with esophagogastric variceal bleeding (EVB) who underwent laparoscopic splenectomy combined with pericardial devascularization (LSPD) versus transjugular intrahepatic portosystemic shunt (TIPS) procedures.

METHODS

A retrospective collection of medical records was conducted from January 2014 to May 2020 at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. The study included patients from the departments of trauma surgery, interventional radiology, and general surgery who were diagnosed with EVB caused by portal hypertension and treated with LSPD or TIPS. Follow-up data were obtained to assess the occurrence of postoperative complications in both groups.

RESULTS

A total of 201 patients were included in the study, with 104 cases in the LSPD group and 97 cases in the TIPS group. There was no significant difference in the 1-year and 3-year post-surgery survival rates between the TIPS and LSPD groups (P = 0.669, 0.066). The 3-year survival rate of Child-Pugh B patients in the LSPD group was higher than TIPS group (P = 0.041). The LSPD group also had a significantly higher rate of freedom from rebleeding at 3-year post-surgery compared to the TIPS group (P = 0.038). Stratified analysis showed no statistically significant difference in the rebleeding rate between the two groups. Furthermore, the LSPD group had a higher rate of freedom from overt hepatic encephalopathy at 1-year and 3-year post-surgery compared to the TIPS group (P = 0.007, < 0.001). The LSPD group also had a lower rate of severe complications at 3-year post-surgery compared to the TIPS group (P = 0.020).

CONCLUSION

Compared to TIPS, LSPD does not increase the risk of mortality and rebleeding, while demonstrating fewer complications. In patients classified as Child-Pugh A and B, the use of LSPD for treating EVB is both safe and effective.

Comparison of long-term outcomes of splenectomy with periesophagogastric devascularization and transjugular intrahepatic portosystemic shunt in treating cirrhotic portal hypertension patients with recurrent variceal bleeding

PURPOSE

Transjugular intrahepatic portosystemic shunt (TIPS) and splenectomy with periesophagogastric devascularization (SPD) are widely used to treat cirrhotic portal hypertension (PH) and prevent variceal rebleeding. However, direct comparisons between these two approaches are rare. This study was designed to compare the long-term outcomes of TIPS and SPD in patients with cirrhotic PH and variceal rebleeding.

METHODS

The study included cirrhotic PH patients with a history of gastroesophageal variceal bleeding between 18 and 80 years of age who were admitted to the Third Affiliated Hospital of Sun Yat-sen University from January 2012 to January 2022. Patients were enrolled into two groups according to TIPS or SPD was performed. Baseline characteristics were matched using propensity score matching (PSM).

RESULTS

A total of 230 patients underwent TIPS, while 184 underwent SPD. PSM was carried out to balance available covariates, resulting in a total of 83 patients in the TIPS group and 83 patients in the SPD group. Patients in SPD group had better liver function during 60 months follow-up. Five-year overall survival rates in SPD group and TIPS group were 72 and 27%, respectively, at 2 years were 88 and 86%, respectively. The 2- and 5-year freedom from variceal rebleeding rates were 95 and 80% in SPD group and 80 and 54% in TIPS group.

CONCLUSIONS

SPD is clearly superior to TIPS in terms of OS and freedom from variceal rebleeding in patients with cirrhotic PH. In addition, SPD improved liver function in patients with cirrhotic PH.

Progress in clinical diagnosis and treatment of cavernous transformation of the portal vein

Cavernous transformation of the portal vein (CTPV) refers to the compensatory neoformation of venous collaterals around the hepatic portal after the main portal vein or its branches are blocked, in order to maintain liver blood perfusion. This disease is relatively rare, and in clinical practice, its etiology, diagnosis, and treatment are not well understood. Patients with portal hypertension-related syndromes need to receive active treatment. The main goal of treatment is to prevent upper gastrointestinal hemorrhage and hypersplenism caused by portal hypertension, and to restore hepatopetal portal blood perfusion. It is necessary to fully assess the patient's condition and understand the best indications for each treatment. On this basis, we should adopt individualized comprehensive treatment strategies. This article reviews the latest advances in the understanding of the etiology, diagnosis, classification, and treatment of CTPV.

Transjugular intrahepatic portosystemic shunt for patients with liver cirrhosis: survey evaluating indications, standardization of procedures and anticoagulation in 43 German hospitals

OBJECTIVES

Transjugular intrahepatic portosystemic shunt (TIPS) insertion is an established treatment to lower portal pressure. There are no obligatory evidence-based recommendations addressing procedure and anticoagulation. Therefore, a survey was performed to establish current practice at different German hospitals.

METHODS

A three-page survey was sent out via postal mail to 76 different hospitals addressing the topics indication, contraindication, follow-up and anticoagulation.

RESULTS

Forty-three hospitals completed the survey: the median number of TIPS/year was 28.6 ± 23. Ascites and hydrothorax were announced as the main indications. Bilirubin levels above 5 mg/dl, hepatic encephalopathy and cardiac disease were considered as absolute contraindications in most hospitals, but age was not. The biggest variations were reported with regard to anticoagulation after TIPS procedure. Four hospitals never used any anticoagulation; most hospitals reported the use of low molecular weight heparins for a period of days up to 4 weeks. But also aspirin or clopidogrel was used after TIPS insertion in eight different hospitals. Additionally, the standards for follow-up after TIPS insertion were different in the hospitals.

CONCLUSIONS

There is no consensus how to handle indication, contraindications and anticoagulation after the TIPS procedure. A national and international consensus is warranted to improve the outcome of TIPS patients and reduce secondary complications. In addition to compare results and efficacy in the future standard operation procedures as proposed here need to be put in place.

Transjugular intrahepatic portosystemic shunt and splenectomy are more effective than endoscopic therapy for recurrent variceal bleeding in patients with idiopathic noncirrhotic portal hypertension

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS), splenectomy plus esophagogastric devascularization (SED) and endoscopic therapy + non-selective β-blockers (ET + NSBB) are widely applied in secondary prevention of recurrent gastroesophageal variceal bleeding in patients with liver cirrhosis. These different treatments, however, have not been compared in patients with idiopathic non-cirrhotic portal hypertension (INCPH).

AIM

To compare the outcomes of TIPS, SED and ET + NSBB in the control of variceal rebleeding in patients with INCPH.

METHODS

This retrospective study recruited patients from six centers across China. Demographic characteristics, baseline profiles and follow-up clinical outcomes were collected. Post-procedural clinical outcomes, including incidence of rebleeding, hepatic encephalopathy (HE), portal vein thrombosis (PVT) and mortality rates, were compared in the different groups.

RESULTS

In total, 81 patients were recruited, with 28 receiving TIPS, 26 SED, and 27 ET + NSBB. No significant differences in demographic and baseline characteristics were found among these three groups before the procedures. After treatment, blood ammonia was significantly higher in the TIPS group; hemoglobin level and platelet count were significantly higher in the SED group (P < 0.01). Rebleeding rate was significantly higher in the ET + NSBB group (P < 0.01). Mortality was 3.6%, 3.8% and 14.8% in the TIPS, SED and ET + NSBB groups, respectively, with no significant differences (P = 0.082). Logistic regression analysis showed that mortality was significantly correlated with rebleeding, HE, portal thrombosis and superior mesenteric vein thrombosis (P < 0.05).

CONCLUSION

In patients with INCPH, TIPS and SED were more effective in controlling rebleeding than ET + NSBB, but survival rates were not significantly different among the three groups. Mortality was significantly correlated with rebleeding, HE and PVT.

ACR Appropriateness Criteria® Radiologic Management of Gastric Varices

Hemorrhage, resulting from gastric varies, can be challenging to treat, given the various precipitating etiologies. A wide variety of treatment options exist for managing the diverse range of the underlying disease processes. While cirrhosis is the most common cause for gastric variceal bleeding, occlusion of the portal or splenic vein in noncirrhotic states results in a markedly different treatment paradigm. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Transjugular intrahepatic portosystemic shunt for the prevention of recurrent esophageal variceal bleeding in patients with cavernous transformation of portal vein

BACKGROUND

Treatment options for patients with cavernous transformation of portal vein (CTPV) are limited. This study aimed to evaluate the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) to prevent recurrent esophageal variceal bleeding in patients with CTPV.

METHODS

We retrospectively analyzed 67 consecutive patients undergone TIPS from January 2011 to December 2016. All patients were diagnosed with CTPV. The indication for TIPS was a previous episode of variceal bleeding. The data on recurrent bleeding, stent patency, hepatic encephalopathy and survival were retrieved and analyzed.

RESULTS

TIPS procedure was successfully performed in 56 out of 67 (83.6%) patients with CTPV. TIPS was performed via a transjugular approach alone (n = 15), a combined transjugular/transhepatic approach (n = 33) and a combined transjugular/transsplenic approach (n = 8). Mean portosystemic pressure gradient (PSG) decreased from 28.09 ± 7.28 mmHg to 17.53 ± 6.12 mmHg after TIPS (P < 0.01). The probability of the remaining free recurrent variceal bleeding was 87.0%. The probability of TIPS patency reached 81.5%. Hepatic encephalopathy occurrence was 27.8%, and survival rate was 88.9% until the end of follow-up. Four out of 11 patients who failed TIPS died, and 4 had recurrent bleeding.

CONCLUSIONS

TIPS should be considered a safe and feasible alternative therapy to prevent recurrent esophageal variceal bleeding in patients with CTPV, and to achieve clinical improvement.

Adverse factors responsible for below-normal platelet count after laparoscopic splenectomy and azygoportal disconnection

BACKGROUND/AIMS

Splenectomy is regarded as an effective curative treatment for thrombocytopenia caused by hypersplenism in patients with cirrhosis. However, in clinical practice, thrombocytopenia is not resolved by splenectomy in all patients. This study aimed to evaluate the adverse factors responsible for platelet (PLT) counts below the normal lower limit following laparoscopic splenectomy and azygoportal disconnection (LSD).

MATERIALS AND METHODS

We retrospectively evaluated the outcomes of 123 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism, who underwent LSD and who had PLT counts <125×109/L (non-normal group) or >125×109/L (normal group) at the postoperative month (POM) 3, between April 2014 and March 2017.

RESULTS

Sixteen patients (13.01%) had PLT counts <125×109/L at POM 3 after LSD, while the remaining 107 patients had normal counts. We analyzed 25 perioperative variables in both groups. A logistic multivariate regression identified age (relative risk [RR] 1.082, 95% confidence interval [CI] 1.018-1.150) and longitudinal spleen diameter (RR 0.977, 95% CI 0.955-1.000) as significant independent factors for the PLT count <125×109/L at POM 3. Bivariate correlation analysis showed that age >50 years and longitudinal spleen diameter <160 mm were threshold values for an increased risk of the PLT count <125×109/L at POM 3 after LSD.

CONCLUSION

Age was an independent positive predictor and longitudinal spleen diameter an independent negative predictor of PLT count <125×109/L at POM 3 after LSD.

Recurrent esophagogastric variceal bleeding due to portal vein thrombosis caused by protein S deficiency

Background and study aims  Esophagogastric variceal bleeding (EGVB) is common in patients with portal vein thrombosis (PVT). Hereditary deficiencies in natural anticoagulant proteins, such as protein S, might contribute to PVT. However, recurrent EGVB caused by PVT in patients with protein S deficiency is seldom reported. Herein, we present the case of a 38-year-old man with protein S deficiency complicated with PVT. The patient suffered recurrent EGVB for 7 years. He underwent splenectomy plus pericardial revascularization and sequential endoscopic therapy, including one gastric variceal obturation (GVO) procedure and two esophageal variceal ligations (EVL) to eradicate the varices. Rivaroxaban was administrated to reduce risk of thrombotic events. The patient is currently well without rebleeding after 1 year of follow-up. To our knowledge there is no consensus on management of recurrent EGVB on the basis of thrombophilia complicated with PVT. According to our practice, sequential endoscopic therapy combined with anticoagulant appears to be effective and safe.
