Predictors and management of post-banding ulcer bleeding in cirrhosis: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Post-banding ulcer bleeding (PBUB) is an understudied complication of oesophageal varices endoscopic band ligation (EBL). This systematic review with meta-analysis aimed at: (a) evaluating the incidence of PBUB in patients with cirrhosis treated with EBL in primary or secondary prophylaxis or urgent treatment for acute variceal bleeding and (b) identifying predictors of PBUB. METHODS: We conducted a systematic review of articles in English published in 2006-2022 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Searches were made in eight databases including Embase, PubMed and Cochrane Library. Random-effects meta-analysis was used to determine the incidence, mean interval and predictors of PBUB. RESULTS: Eighteen studies (9034 patients) were included. The incidence of PBUB was 5.5% (95% CI 4.3-7.1). The mean time for it to occur was 11 days (95% CI 9.94-11.97). Model for End-stage Liver Disease (MELD) score (OR 1.162, 95% CI 1.047-1.291) and EBL done in emergency setting (OR 4.902, 95% CI 2.99-8.05) independently predicted post-ligation ulcer bleeding. Treatment included drugs, endoscopic procedures and transjugular intrahepatic portosystemic shunt. Refractory bleeding was treated with self-expandable metallic stents or balloon tamponade. Mortality was on average 22.3% (95% CI 14.1-33.6). CONCLUSIONS: Patients with high MELD score and receiving EBL in an emergency setting are more prone to develop PBUB. Prognosis is still poor and the best therapeutic strategy to address remains to be ascertained.

Band-assisted endoscopic mucosal resection for small (≤ 1.5 cm) submucosal tumors originating from the muscularis propria in the gastric fundus: a prospective study.

BACKGROUND: To date, no prospective study has compared the safety and efficacy of band-assisted endoscopic mucosal resection (BA-EMR) with those of endoscopic dissection (ESD) for the treatment of submucosal tumors (SMTs) in the gastric fundus. We aimed to compare the safety and efficacy of BA-EMR with those of ESD for SMTs ≤ 1.5 cm in the gastric fundus. METHODS: In total, 62 patients with SMTs ≤ 1.5 cm in the gastric fundus underwent band ligation; the lesions that could be completely ligated were excised using a snare, while others were removed by ESD. RESULTS: Of 62 patients, 42 had their lesions completely ligated by the band and underwent BA-EMR, while 20 had lesions that could not be completely ligated and underwent ESD. The average tumor size was 0.94 ± 0.16 and 1.30 ± 0.16 cm in the BA-EMR and ESD groups, respectively. Compared with ESD, BA-EMR had significantly fewer complications and a significantly shorter mean operating time and hospital stay. CONCLUSION: BA-EMR is a safe and effective method for small SMTs in the gastric fundus, but is only suitable for SMTs < 1.2 cm. For small SMTs (< 1.2 cm) in the gastric fundus, BA-EMR may simplify the treatment procedure, shorten the operation time, and reduce complications.

Comparisons Between Endoscopic Band Ligation, Radiofrequency Ablation and Endoscopic Thermal Therapy for Gastric Antral Vascular Ectasia: A Meta-Analysis.

BACKGROUND: Endoscopic band ligation (EBL) and radiofrequency ablation (RFA) have emerged as alternative therapies of gastric antral vascular ectasia (GAVE) in addition to endoscopic thermal therapy (ETT), but the optimum choice remains inconclusive. AIM: We conducted a meta-analysis in order to compare these three treatments for GAVE. METHODS: We searched the electronic databases of PubMed, Embase and Cochrane Central Register of Controlled Trials without any language restrictions and also performed a manual literature search of bibliographies located in both retrieved articles and published reviews for eligible publications prior to December 8, 2021. We included comparative trials which had evaluated the efficacy and safety of interventions in adults (aged ≥ 18 years) diagnosed with symptomatic GAVE and was confirmed according to clinical backgrounds and upper gastrointestinal endoscopy. We included reports that compared three interventions, ETT, EBL, and RFA. The study was comprised of adults diagnosed with GAVE and focused on overall mortality, bleeding cessation, endoscopic improvement, complications, hospitalization, hemoglobin improvement, number of sessions and transfusion requirements. RESULTS: Twelve studies were performed involving a total of 571 participants for analysis. When compared with ETT, EBL achieved better bleeding cessation (OR 4.48, 95% CI 1.36-14.77, p = 0.01), higher hemoglobin improvement (MD 0.57, 95% CI 0.31-0.83, p < 0.01) and lower number of sessions (MD - 1.44, 95% CI - 2.54 to - 0.34, p = 0.01). Additionally, EBL was superior to ETT in endoscopic improvement (OR 6.00, 95% CI 2.26-15.97, p < 0.01), hospitalization (MD - 1.32, 95% CI - 1.91 to - 0.74, p < 0.01) and transfusion requirement (MD - 2.66, 95% CI - 4.67 to - 0.65, p = 0.01) with statistical significance, with the exception of mortality (OR 0.58, 95% CI 0.19-1.77, p = 0.34) and complication rate (OR 5.33, 95% CI 0.58-48.84, p = 0.14). CONCLUSION: For GAVE, we suggest that EBL be initially recommended, and APC and RFA be used as alternative treatment choices based upon a very low quality of evidence.

Cumulative evidence for reducing recurrence of colonic diverticular bleeding using endoscopic clipping versus band ligation: Systematic review and meta-analysis.

BACKGROUND AND AIM: Either clipping or band ligation will become the most common endoscopic treatment for colonic diverticular bleeding (CDB). Rebleeding is a significant clinical outcome of CDB, but there is no cumulative evidence comparing reduction of short-term and long-term rebleeding between them. Thus, we conducted a systematic review and meta-analysis to determine which endoscopic treatment is more effective to reduce recurrence of CDB. METHODS: A comprehensive search of the databases PubMed/MEDLINE and Embase was performed through December 2019. Main outcomes were early and late rebleeding rates, defined as bleeding within 30 days and 1 year of endoscopic therapy for CDB. Initial hemostasis, need for transcatheter arterial embolization, or surgery were also assessed. Overall pooled estimates were calculated. RESULTS: Sixteen studies fulfilled the eligibility criteria, and a total of 790 participants were included. The pooled prevalence of early rebleeding was significantly lower for band ligation than clipping (0.08 vs 0.19; heterogeneity test, P = 0.012). The pooled prevalence of late rebleeding was significantly lower for band ligation than clipping (0.09 vs 0.29; heterogeneity test, P = 0.024). No significant difference of initial hemostasis rate was noted between the two groups. Pooled prevalence of need for transcatheter arterial embolization or surgery was significantly lower for band ligation than clipping (0.01 vs 0.02; heterogeneity test, P = 0.031). There were two cases with colonic diverticulitis due to band ligation but none in clipping. CONCLUSION: Band ligation therapy was more effective compared with clipping to reduce recurrence of colonic diverticular hemorrhage over short-term and long-term durations.

Safety and Effectiveness of Endoscopic Band Ligation for Colonic Diverticular Bleeding in Elderly Patients.

INTRODUCTION: Colonic diverticulosis increases with age, leading to a higher risk of colonic diverticular bleeding (CDB) in the elderly. As life expectancy continues to increase, the need for endoscopic hemostasis for CDB in the elderly can also be expected to increase. However, there have been no reports to date on the feasibility of endoscopic hemostasis for elderly CDB patients. Several recent studies have addressed the effectiveness of endoscopic band ligation (EBL) for CDB. In this study, we evaluate the safety and effectiveness of EBL in elderly CDB patients compared to younger CDB patients. METHODS: We retrospectively analyzed the medical records of consecutive patients treated with EBL for the first time at a tertiary referral center between March 2011 and November 2017. Patients were grouped according to age into those at least 75 years old (the Elderly) and those <75 years old (the Nonelderly). Patient characteristics, technical success, and complications were compared between the two groups. RESULTS: EBL was performed in 153 patients during the study period (49 Elderly patients and 104 Nonelderly patients). Elderly patients were less likely to be male (p < 0.001) and had lower hemoglobin levels on admission (p < 0.001). Bleeding on the right side of the splenic flexure was observed more frequently in the Nonelderly (p = 0.002). Charlson Comorbidity Index (CCI) and use of antithrombotic agents were significantly higher in the Elderly (p < 0.001 and p < 0.001, respectively). Active bleeding tended to be observed more frequently in the Elderly (p = 0.054), while the difference was not significant. There were no significant differences in the shock index, procedure time, or units of packed red blood cells transfused between the 2 groups. No significant differences in the technical success rate (97.1 vs. 98%, p = 0.76), early rebleeding rate (10.2 vs. 14.4%, p = 0.47), or other complications (2 vs. 1%, p = 0.58) were observed. Perforation and abscess formation were not observed in either group. Female gender, left-sidedness, higher CCI, and lower hemoglobin level were all significantly more frequently observed in the Elderly on multiple logistic regression analysis. DISCUSSION/CONCLUSION: EBL may be similarly safe and effective for the treatment of CDB in the elderly as in the nonelderly.

Over-the-scope clip for acute esophageal variceal bleeding.

Over-the-scope clip (OTSC) has been reported to control non-variceal bleeding; however, the use of this device for acute variceal hemorrhage (AVH) is very limited. We report our experience regarding the use of OTSC in patients with AVH in terms of technical success and safety. A retrospective clinical experience case series study was conducted from October 2017 to June 2019 at two tertiary care centers. Adult patients with AVH as a result of small varices managed with OTSC after endoscopic band ligation (EBL) failure were enrolled. Standard gastroscope and OTSC 'type a' with a cap of 11 mm in diameter were used in all procedures. Total of five patients with chronic liver disease (Child-Pugh score ≤8) and portal hypertension (hepatic venous pressure gradient, mean 14.4 ± 1.3 mmHg) were included. Four of them presented collapse of the bleeding varix, and one had wall disruption associated with fibrosis secondary to prior banding. We were able to stop AVH in all patients without clip-related adverse events during a 30-day follow-up period. Two patients developed solid food dysphagia after 3 months of clip deployment that resolved after removal using a bipolar cutting device. Twin grasper or anchor were not used to aid or facilitate the approximation of opposite edges in any patient. No additional local therapies or new endoscopic session for variceal eradication were required. This case series shows preliminary success controlling AVH with OTSC after EBL failure in patients with small varices. Esophageal dysphagia may appear as a complication during follow up but it can be resolved by clip removal.

High Cost of Hospitalization for Colonic Diverticular Bleeding Depended on Repeated Bleeding and Blood Transfusion: Analysis with Diagnosis Procedure Combination Data in Japan.

BACKGROUND: Bleeding from a colonic diverticulum is serious in aged patients. The aim of this study was to determine the risk factors for high-cost hospitalization of colonic diverticular bleeding using the diagnosis procedure combination (DPC) data. METHODS: From January 2009 to December 2015, 78 patients with colonic diverticular bleeding were identified by DPC data in Saga Medical School Hospital. All patients underwent colonic endoscopy within 3 days. The patients were divided into 2 groups: the low-cost group (DPC cost of <500,000 yen) and the high-cost group (DPC cost of >500,000 yen). RESULTS: Univariate analysis revealed that aging, hypertension, rebleeding, a low hemoglobin concentration at admission, and blood transfusion were risk factors for high hospitalization cost. Multivariate analysis revealed that rebleeding (OR 5.3; 95% CI 1.3-21.3; p = 0.017) and blood transfusion (OR 3.8; 95% CI 1.01-14.2; p = 0.048) were definite risk factors for high hospitalization cost. CONCLUSION: Rebleeding and blood transfusion were related to high hospitalization cost for colonic diverticular bleeding.

Endoscopic band ligation versus endoscopic submucosal dissection and laparoscopic resection for small gastric stromal tumors.

BACKGROUND AND AIM: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Previous studies have addressed the safety and feasibility of endoscopic band ligation (EBL) for the treatment of small gastric GISTs. However, published reports comparing EBL with other interventions are limited. This current study evaluates the efficacy of EBL and compares EBL to both endoscopic submucosal dissection (ESD) and laparoscopic resection (LAP) for small gastric GISTs less than 15 mm. METHODS: A total of 339 patients who underwent endoscopic therapy or laparoscopic resection for gastric GISTs between 1998 and 2012 were retrospectively identified and collected from medical records in our hospital. The parameters measured for each procedure type includes clinicopathological characteristics, length of stay, hospitalization expense and surgical outcomes. RESULTS: Among the 147 patients included in our study, 72 (48.98 %) received EBL, 27 (18.37 %) received ESD, and 48 (32.65 %) received LAP. The demographic and clinical characteristics of the patients such as gender, age, tumor site and size were well balanced between the study groups. There was also no significant difference in follow-up time between the study groups. The mean operating time was significantly shorter in the patients receiving EBL than patients receiving ESD and LAP (p < 0.001). The estimated blood loss was significantly different between the three groups (p < 0.001). Complications occurred in 1.39 % of the patients receiving EBL, 18.52 % of the patients receiving ESD and 4.17 % of the patients receiving LAP (p = 0.004), and recurrence rate in 15.00, 9.10 and 11.76 %, respectively (p = 0.705). There was also significant difference about mean hospital stay and hospital cost between three groups (p < 0.001). CONCLUSION: Our results show a significant advantage in the short-term outcome for EBL compared to ESD and LAP. However, long-term randomized controlled trials are needed to compare the three methods for the treatment of small GISTs.

Endoscopic ultrasound findings predict the recurrence of esophageal varices after endoscopic band ligation: a prospective cohort study.

OBJECTIVE: Variceal recurrence following endoscopic band ligation (EBL) is common. Esophageal collateral veins (ECV) are observed by endoscopic ultrasound (EUS) in patients with portal hypertension. The aim of the present study was to assess the role of EUS in predicting the recurrence of esophageal varices following EBL. MATERIAL AND METHODS: Forty patients who had undergone EBL for eradication of varices were examined over a 12-month period to detect variceal recurrence. EUS was performed before ligation to detect and describe the type, grade, and the number of ECV. EUS findings obtained prior to EBL were compared in the variceal recurrence and non-recurrence groups. RESULTS: Of the 40 patients, 19 (47.5%) had variceal recurrence within 12 months of EBL. Univariate logistic regression analysis showed that severe peri-ECV (p < 0.001), multiple peri-ECV (p < 0.001), and the presence of perforating veins (p < 0.014) were statistically significantly related to the variceal recurrence after EBL. Multivariate logistic regression model found that only severe peri-ECV (odds ratio [OR] = 24.39; 95% confidence interval [CI]: 2.34-253.78) and multiple peri-ECV (OR = 24.39; 95% CI: 2.34-253.78) remained as independent prognostic factors for variceal recurrence. The sensitivity and specificity of multivariate logistic regression model in predicting variceal recurrence was 89.2% and 90.5%, respectively (prognostic value (AUC) = 0.946). CONCLUSION: Recurrence rate of esophageal varices after EBL is high (47.5%). EUS can clearly depict ECV and has a value in predicting variceal recurrence after EBL; severe peri-ECV and multiple peri-ECV were significant and independent prognostic factors associated with variceal recurrence risk.

Comparison of endoscopic band ligation and endoclip closure of colonic perforation: technical feasibility and efficacy in an ex vivo pig model.

BACKGROUND AND AIM: Recent reports have indicated several instances of successful treatment of bowel perforation by using endoscopic band ligation (EBL) when treatment with endoclipping is unsuccessful, but this salvage method has not been investigated in any prospective model. Herein we aimed to compare the technical feasibility and efficacy of EBL and endoclip use in intraluminal closure of colon perforation, in an ex vivo model. METHODS: Standardized colonic perforations were created using fresh porcine colon and subsequently closed by full-thickness interrupted sutures, endoclip (QuickClip2(TM)), or EBL. Each closure site was tested with compressed air by using a digital pressure monitor for evaluating leak pressure. RESULTS: No significant differences were noted between the endoclip and EBL in leak pressures. Mean (± SD) pressures for air leakage from the perforations closed using the different devices were as follows: normal colon samples, 52.0 ± 13.2 mmHg; perforations closed with hand-sewn sutures, 32.3 ± 8.3 mmHg; perforations closed with endoclipping, 53.5 ± 22.7 mmHg; and perforations closed with EBL, 50.4 ± 12.5 mmHg. Time taken for closure by EBL was significantly less than that for closure by endoclipping (3.2 ± 1.7 min vs 6.8 ± 1.3 min, P < 0.01). Further, the number of devices used to achieve complete closure in the EBL group was lower than that with endoclipping (1.6 ± 0.5 vs 3.7 ± 0.8, P < 0.01). CONCLUSION: Endoluminal closure of a 1.5-cm colon perforation with EBL decreased procedure time and was not inferior in leak pressure compared with endoclipping in this ex vivo porcine model.

Influence of COVID-19 on Patients with Esophageal Varices under Prophylactic Endoscopic Band Ligation Therapy.

Background and Objectives: Endoscopic band ligation (EBL) plays a critical role in patients with clinically significant portal hypertension, as variceal eradication (VE) is essential to prevent further variceal upper gastrointestinal bleeding (GI). The emergence of COVID-19 has led to a dramatic reduction in endoscopic activity. Our study aimed to evaluate the effect of COVID-19 on VE, GI, and 6-month mortality of patients treated with prophylactic EBL therapy. In addition, our goal was to identify the risk factors for our proposed outcomes. Methods: A single-center retrospective cohort study included patients with esophageal varices treated with prophylactic EBL therapy between 2017 and 2021. To demonstrate the impact of COVID-19 on two independent groups on prophylactic EBL therapy with 1 year of follow-up, March 2019 was selected as the cut-off date. Clinical, laboratory, and endoscopic data were recovered from electronic reports. Results: Ninety-seven patients underwent 398 prophylactic EBL sessions, 75 men (77.3%) with mean age 59 ± 12 years. Most achieved VE (60.8%), 14.4% had GI bleeding post-therapy, and 15.5% died at 6 months. The rate of variceal obliteration was significantly lower in the pandemic group (40.9% vs. 77.4% in the pre-pandemic group, p = 0.001). Mean number of EBL sessions and pandemic group were independently associated with incomplete VE, while MELD-Na, portal vein thrombosis and failed VE were identified as risk factors associated with mortality at 6 months. Conclusions: Almost 60% of patients in the pandemic group failed to eradicate esophageal varices. Failure to achieve this result conferred a higher risk of GI bleeding and death at 6 months, the latter also significantly associated with the MELD-Na score and portal vein thrombosis. Our study is among the first to demonstrate the impact of COVID-19 in patients receiving prophylactic EBL therapy.

Introdução e objetivos: A laqueação elástica endoscópica (LEE) é crucial nos doentes com hipertensão portal clinicamente significativa, uma vez que permite a erradicação das varizes esofágicas (EVE) que, por sua vez, previne a hemorragia digestiva varicosa. Com o início da pandemia COVID-19, a atividade endoscópica foi drasticamente reduzida. Com este estudo pretendemos avaliar a influência da COVID-19 na EVE, hemorragia gastrointestinal (GI) e mortalidade aos 6 meses dos doentes sob LEE profilática, assim como identificar os seus fatores de risco. Métodos: Estudo de coorte monocêntrico e retrospetivo que incluiu doentes com varizes esofágicas sob LEE profilática entre 2017 e 2021. Para demonstrar o impacto da pandemia COVID-19 em dois grupos independentes sob LEE profilática durante um ano de follow-up, a escolha da data-limite foi Março de 2019. Os dados clínicos, laboratoriais e endoscópicos foram obtidos a partir dos relatórios eletrónicos. Resultados: Noventa e sete doentes cumpriram 398 sessões de LEE, 75 homens (77,3%), com idade média de 59 ± 12 anos. A maioria dos doentes obteve EVE (60,8%), 14,4% desenvolveu hemorragia GI e 15,5% faleceu nos primeiros 6 meses pós-terapêutica. A taxa de EVE foi significativamente inferior no grupo pandémico (40,9% vs. 77,4% no grupo pré-pandémico, p = 0.001). O número médio de sessões de LEE e o grupo pandémico foram independentemente associados à EVE incompleta; enquanto MELD-NA, trombose da veia porta e falha na EVE foram identificados como fatores de risco associados à mortalidade aos 6 meses. Conclusão: Cerca de 60% dos doentes no grupo pandémico não conseguiu erradicar as varizes esofágicas. A EVE incompleta aumenta o risco de hemorragia GI e mortalidade aos 6 meses, esta última também associada de forma significativa ao score MELD-Na e TVP. O nosso estudo foi pioneiro na demonstração do impacto da pandemia COVID-19 nos doentes sob LEE profilática.

Navigating the controversy regarding antibiotic prophylaxis in acute variceal bleeding.

Antibiotic prophylaxis in patients with cirrhosis and acute variceal bleeding is part of the standard of care according to most clinical guidelines. However, with recent evidence arguing against antibiotic prophylaxis, the role of this intervention has become less clear.

Endoscopic band ligation versus hot snare resection for hyperplastic gastric polyps in cirrhotic patients.

Managing patients with liver cirrhosis and gastric hyperplastic polyps (GHPs) is challenging. Despite being the standard technique for resection of GHPs, hot snare polypectomy (HSP) is risky in the setting of coagulation disorders associated with liver cirrhosis. The aim of the study was to assess the efficacy and safety of endoscopic band ligation (EBL), compared to HSP in resecting GHPs in cirrhotic patients. One hundred consecutive adults with liver cirrhosis and sessile or pedunculated GHPs were enrolled from December 2018 to December 2020. Cases were non-blindly randomized (1 : 1) to two groups to have GHPs managed by either EBL (group I) or HSP (group II). Data of demographic, clinical, and pathological factors, hospitalization expenses and outcomes of both treatment maneuvers were collected and statistically analyzed. Upper endoscopy was repeated for all patients at 3, 6 and 12 months after treatment for recurrence detection. Between the two procedures, the mean operational time was significantly shorter in the EBL than the HSP group (15.1 ±3.80 min vs. 36.6 ±6.72 min, p < 0.001). Concerning complications, 94% of EBL cases had reported no complications compared to 78% with HSP. Bleeding occurred only with HSP (20%) with urgent need for adrenaline and/or argon plasma coagulation (p = 0.003). Regarding cost, it was significantly lower in EBL than HSP (280 ±2.02 EGP vs. 390 ±181.8 EGP, p < 0.001). However, the recurrence rate of GHPs and number of needed sessions were not significantly different. EBL proved to be a safer, more rapid, and economic maneuver when compared to HSP on resecting GHPs in patients with liver cirrhosis.

Safety and efficacy of transjugular intrahepatic portosystemic shunts vs endoscopic band ligation plus propranolol in patients with cirrhosis with portal vein thrombosis: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to assess the efficacy and safety of transjugular intrahepatic portosystemic shunts (TIPS) against the combined treatment of endoscopic band ligation (EBL) and propranolol in managing patients with cirrhosis diagnosed with portal vein thrombosis (PVT). METHODS: A literature search from inception to September 2023 was performed using MEDLINE, the Cochrane Library, Web of Science, and Scopus. Independent screening, data extraction, and quality assessment were performed. The main measured outcomes were the incidence and recurrence of variceal bleeding (VB), hepatic encephalopathy, and overall survival. RESULTS: A total of 5 studies were included. For variceal eradication, there was initially no significant difference between the groups; however, after sensitivity analysis, a significant effect emerged (risk ratio [RR], 1.55; P < .0001). TIPS was associated with a significant decrease in the incidence of VB (RR, 0.34; P < .0001) and a higher probability of remaining free of VB in the first 2 years after the procedure (first year: RR, 1.41; P < .0001; second year: RR, 1.58; P < .0001). TIPS significantly reduced the incidence of death due to acute GI bleeding compared with EBL + propranolol (RR, 0.37; P = .05). CONCLUSION: TIPS offers a comprehensive therapeutic advantage over the combined EBL and propranolol regimen, especially for patients with cirrhosis with PVT. Its efficacy in variceal eradication, reducing rebleeding, and mitigating death risks due to acute GI bleeding is evident.

Endoscopic band ligation or endoscopic tissue adhesive injection in the treatment of gastric varices: Which is better?

The combination of endoscopic ultrasound with endoscopic treatment of type 1 gastric variceal hemorrhage may improve the robustness and generalizability of the findings in future studies. Moreover, the esophageal varices should also be included in the evaluation of treatment efficacy in subsequent studies to reach a more convincing conclusion.

Evaluation of the efficacy and safety of endoscopic band ligation in the treatment of bleeding from mild to moderate gastric varices type 1.

BACKGROUND: According to practice guidelines, endoscopic band ligation (EBL) and endoscopic tissue adhesive injection (TAI) are recommended for treating bleeding from esophagogastric varices. However, EBL and TAI are known to cause serious complications, such as hemorrhage from dislodged ligature rings caused by EBL and hemorrhage from operation-related ulcers resulting from TAI. However, the optimal therapy for mild to moderate type 1 gastric variceal hemorrhage (GOV1) has not been determined. Therefore, the aim of this study was to discover an individualized treatment for mild to moderate GOV1. AIM: To compare the efficacy, safety and costs of EBL and TAI for the treatment of mild and moderate GOV1. METHODS: A clinical analysis of the data retrieved from patients with mild or moderate GOV1 gastric varices who were treated under endoscopy was also conducted. Patients were allocated to an EBL group or an endoscopic TAI group. The differences in the incidence of varicose relief, operative time, operation success rate, mortality rate within 6 wk, rebleeding rate, 6-wk operation-related ulcer healing rate, complication rate and average operation cost were compared between the two groups of patients. RESULTS: The total effective rate of the two treatments was similar, but the efficacy of EBL (66.7%) was markedly better than that of TAI (39.2%) (P < 0.05). The operation success rate in both groups was 100%, and the 6-wk mortality rate in both groups was 0%. The average operative time (26 min) in the EBL group was significantly shorter than that in the TAI group (46 min) (P < 0.01). The rate of delayed postoperative rebleeding in the EBL group was significantly lower than that in the TAI group (11.8% vs 45.1%) (P < 0.01). At 6 wk after the operation, the healing rate of operation-related ulcers in the EBL group was 80.4%, which was significantly greater than that in the TAI group (35.3%) (P < 0.01). The incidence of postoperative complications in the two groups was similar. The average cost and other related economic factors were greater for the EBL than for the TAI (P < 0.01). CONCLUSION: For mild to moderate GOV1, patients with EBL had a greater one-time varix eradication rate, a greater 6-wk operation-related ulcer healing rate, a lower delayed rebleeding rate and a lower cost than patients with TAI.

Bleeding Complications of Portal Hypertension.

In portal hypertension, acute variceal bleed is the cause of 2/3rd of all upper gastrointestinal bleeding episodes. It is a life-threatening emergency in patients with cirrhosis. Nonselective beta-blockers by decreasing the hepatic venous pressure gradient are the mainstay of medical therapy for the prevention of variceal bleeding and rebleeding. Evaluation of the severity of bleed, hemodynamic resuscitation, prophylactic antibiotic, and intravenous splanchnic vasoconstrictors should precede the endoscopy procedure. Endoscopic band ligation is the recommended endotherapy. Rescue transjugular intrahepatic port-systemic shunt (TIPS) is recommended for variceal bleed refractory to endotherapy. In patients with a high risk of failure of combined pharmacologic and endoscopic therapy, pre-emptive TIPS may improve the outcome. For gastric varices, "Sarin classification" is universally applied as it is simple and has therapeutic implication. For IGV1 and GOV2, injection cyanoacrylate glue is considered the endotherapy of choice. Endoscopic ultrasound is a useful modality in the management of gastric varices.

Band ligation of gastric antral vascular ectasia is a safe and effective endoscopic treatment.

BACKGROUND AND AIM: Gastric antral vascular ectasia (GAVE) or 'watermelon stomach' is a rare and often misdiagnosed cause of occult upper gastrointestinal bleeding. Treatment includes conservative measures such as transfusion and endoscopic therapy. A recent report suggests that endoscopic band ligation (EBL) offers an effective alternative treatment. The aim of the present study is to demonstrate our experiences with this novel technique, and to compare argon plasma coagulation (APC) with EBL in terms of safety and efficacy. METHODS: A retrospective analysis of all endoscopies with a diagnosis of GAVE was carried out between 2004 and 2010. Case records were examined for information pertaining to the number of procedures carried out, mean blood transfusions, mean hemoglobin, and complications. RESULTS: A total of 23 cases of GAVE were treated. The mean age was 73.9 (55-89) years. Female to male ratio was 17:6 and mean follow up was 26 months. Eight patients were treated with EBL with a mean number of treatments of 2.5 (1-5). This resulted in a statistically significant improvement in the endoscopic appearance and a trend towards fewer transfusions. Of the eight patients treated with EBL, six (75%) patients had previously failed APC treatment despite having a mean of 4.7 sessions. Band ligation was not associated with any short- or medium-term complications. The 15 patients who had APC alone had a mean of four (1-11) treatments. Only seven (46.7%) of these patients had any endoscopic improvement with a mean of four sessions. CONCLUSIONS: EBL represents a safe and effective treatment for GAVE.

Endoscopic band ligation is safe despite low platelet count and high INR.

BACKGROUND: Prophylactic endoscopic band ligation (EBL) is used to prevent variceal bleeding in patients with liver cirrhosis. The association of thrombocytopenia, high INR (international normalized ratio) and liver dysfunction with the risk of procedure-related bleeding (PRB) remains debated and recommendations are controversial. METHODS: We analyzed real-life data of cirrhotic patients undergoing elective EBL at two large Viennese centers between Q1/2000-Q1/2018. PRB was defined as bleeding occurring within 30 days after EBL. RESULTS: We included 617 patients undergoing a total of 1178 prophylactic EBL procedures (median 2 per patient). Sixteen (2.6%) of 617 patients experienced PRB after a median of 12.5 (IQR 17.3) days with no difference in characteristics and laboratory values between the two groups. The proportion of patients with platelets (PLT) < 50 G/L or INR ≥ 1.5 was similar in patients with vs. without PRB. A higher MELD showed a non-significant association with EBL-related bleeding risk (odds ratio, OR 1.07; 95% confidence interval 95% CI 1.00-1.16, p = 0.058). While serum bilirubin was a significant predictor for PRB (OR: 1.10; 95% CI 1.03-1.18), the presence of large varices (OR 0.85 vs. small varices; 95% CI 0.20-3.84), INR (OR 0.50; 95% CI 0.10-3.14), PLT (OR 1.00; 95% CI 1.00-1.01) and the use of non-selective betablockers (OR 1.20; CI 95% 0.38-3.76) were not associated with PRB. CONCLUSION: EBL is safe and procedure-related bleedings are rare (2.6%) including in patients with thrombocytopenia < 50 G/L or high INR ≥ 1.5. Only high MELD, and especially high bilirubin seem to be linked to an increased risk of EBL-related bleeding.

An Economic Analysis of Transjugular Intrahepatic Portosystemic Covered Stent Shunt for Variceal Bleeding and Refractory Ascites in a Spanish Setting.

INTRODUCTION: The primary aim is to estimate the cost-effectiveness of transjugular intrahepatic portosystemic stent shunt (TIPSS) in two indications from a Spanish perspective. Firstly, as pre-emptive treatment for patients with acute variceal bleeding (indication 1) compared with endoscopic band ligation plus drug therapy. Secondly, to treat refractory ascites (indication 2) compared with large volume paracentesis. METHODS: A two-state (alive and dead) Markov model was developed to capture the costs and health impact for the two indications over a 2-year time horizon with monthly cycles. In the alive state, patients could experience adverse event(s), associated with costs and disutility, such as recurrent variceal bleeding, ascites, and hepatic encephalopathy. Discount rates of 3% for utilities and costs and a cost-effectiveness threshold of €25,000 per QALY were applied. RESULTS: In the base case analysis, TIPSS was estimated to be cost-effective as a pre-emptive treatment for indication 1 (incremental cost and QALYs of - €230 and 0.211, respectively). TIPSS also remained cost-effective (€16,819/QALY) in a conservative scenario analysis, conducted with an alternate source for clinical parameters. The key drivers of the outcomes were survival for the comparator arm, mean band ligation outpatient procedures, and TIPSS treatment costs. TIPSS was estimated to dominate the comparator for indication 2 (incremental cost and QALYs of - €25,687 and 0.531, respectively). The key drivers of the outcomes were monthly paracentesis sessions and cost per inpatient stay for those undergoing paracentesis. CONCLUSIONS: TIPSS is likely to be a cost-effective and a cost-saving treatment in patients with cirrhosis in indications 1 and 2, compared with standard treatments. The analyses estimate clinical benefits along with reduced healthcare costs from avoided downstream resource consumption.
