Abstract
AbstractGastric perforation is very rare. Gastric perforation following endoscopic glue injection for gastric varices (GVs) in patients with portal hypertension (PHT) has not been documented till date. They are associated with significant morbidity and mortality. We present a glue injection-induced gastric perforation in patients with PHT that has been treated with primary closure at our institution. To the best of our knowledge, this is the first case report of such complication following endoscopic glue injection for GVs. Such site of glue-induced perforation has not been reported in literature till date. A 38-year-old male patient having cirrhosis of liver with PHT underwent repeated upper gastrointestinal (GI) endoscopic procedures for recurrent upper GI bleed. After 20 days of third endoscopic procedure in which he had undergone glue injection for GVs, patient developed abdominal pain and abdominal radiograph was suggestive of bowel perforation. Emergency laparotomy was performed that showed gastric perforation near to glue injection site which was repaired with primary closure at our institution. Complication such as glue injection-induced gastric perforation has not yet been documented. It is potentially life-threatening. Early recognition may lead to a better prognosis through earlier intervention.

Abstract
Gastrointestinal bleeding as a sequela of portal hypertension can be catastrophic and fatal. Endoscopic and endosonographic therapy play a critical role in management of such bleeding- both for hemostasis of active bleeding and bleeding prophylaxis. Variceal band ligation is established as the standard intervention for esophageal varices. For other sources of portal hypertension-related bleeding, or for salvage therapy for esophageal varices, a variety of endoscopic techniques are available. Endoscopic ultrasound may be used to enhance endoscopic management, particularly for gastric and ectopic varices.

Abstract
BACKGROUND Gastric varices (GV) are associated with high morbidity and mortality in patients with portal hypertension. Endoscopic cyanoacrylate injection is the first-line recommended therapy for GV obliteration. This study aims to explore the reason behind related adverse events and better prevent its occurrence. METHODS A retrospective case series study was conducted from January 1, 2013, to December 31, 2016, to identify patients who experienced severe adverse events secondary to endoscopic cyanoacrylate injection. A literature review of similar cases was performed on two medical databases, Medline and Embase. RESULTS A total of 652 patients underwent cyanoacrylate injection at our center within the study duration. Five cases of severe adverse events related to the use of tissue adhesives were identified. Detailed clinical presentation, patient treatment, and outcomes were reviewed and analyzed. Twenty-seven similar cases were identified based on the literature review providing further insight into the study. CONCLUSION Although rare in incidence, systemic embolism associated with cyanoacrylate injection is often fatal or debilitating. This report may raise awareness in treatment protocol, including the necessity of preoperative angiographic studies, to avoid similar adverse events in clinical practice.

Abstract
PURPOSE OF REVIEW Cyanoacrylate (CYA) therapy has become an important component of the therapeutic toolbox of the interventional endoscopists with direct endoscopic injection accepted as first-line therapy of gastric varices. However, its generalized use has been cautioned by its serious adverse event profile. RECENT FINDINGS Endoscopic ultrasound guided therapy has several conceptual advantages over free-hand injection, particularly as it ensures intravascular delivery of therapy. This has allowed innovation with the use of vascular coils with or without CYA therapy, and very encouraging long-term results are now published showing reduced serious adverse events and low rebleeding rates. SUMMARY Direct endoscopic ultrasound guided intravascular injection of CYA is gaining widespread acceptance and offers reduced complication rates and significantly lower rebleeding rates. Data are supportive of CYA use both for primary and secondary prophylaxis of gastric varices.

Abstract
Expert knowledge of endoscopic management of gastric varices is essential, as these occur in 20% of patients with portal hypertension. Bleeding is relatively uncommon, but carries significant mortality when this occurs. Inability to directly target intravascular injections and the potential complication related to glue embolization has resulted in the development of novel techniques. Direct visualization of the varix lumen using endoscopic ultrasound (EUS) allows targeted therapy of feeder vessels with real-time imaging. EUS-guided combination therapy with endovascular coiling and cyanoacrylate injections promise to provide reduced complication rates, increased obliteration of varices, and reduced long-term rebleeding rates.

Abstract
Acute gastric variceal bleeding (GVB) is a catastrophic problem and accounts for one of the major causes of death in cirrhotic patients. Although, N-butyl cyanoacrylate (NBC) has been shown to control bleeding effectively, it still carries up high mortality rate. This study aimed to find the predictors of mortality within 6 weeks after emergent endoscopic treatment with NBC injection. This retrospective study recruited patients with acute GVB after emergent endoscopic NBC injection between January 2011 and June 2013 in Linkou Medical Center, Chang Gung Memorial Hospital, Linkou, Taiwan. Logistic regression analysis was applied for predictors of mortality within 6 weeks. Statistical significance was set as P < 0.05. There were 132 patients with acute GVB (83.3% men, median age 51.3 years) with endoscopic NBC injection treatments recruited. Mortality within 6 weeks was noted in 16.7% patients. By multivariate analysis, renal function impairment (odds ratio [OR]: 21.1, 95% confidence interval [CI]: 3.06-146.0, P = 0.002), higher Child-Turcotte-Pugh (CTP) score (OR: 2.49, 95% CI: 1.41-4.38, P = 0.002), higher model for end-stage liver disease (MELD) score (OR: 1.18, 95% CI: 1.03-1.35, P = 0.013), rebleeding within 5 days (OR: 16.4, 95% CI: 3.36-79.7, P = 0.001), and acute on chronic liver failure (ACLF) (OR: 4.67, 95% CI: 1.62-13.33, P = 0.004) were independent predictors of mortality within 6 weeks. A MELD score of ≥ 18 was associated with Area Under the Receiver Operating Characteristic (AUROC) of 0.79 (P < 0.001, 95% CI: 0.69-0.90) and a CTP score of ≥ 9 with AUROC of 0.85 (P < 0.001, 95% CI: 0.76-0.94) for determining 6 weeks mortality. Impaired renal function, deteriorated liver function with CTP score ≥ 9 as well as MELD score ≥ 18, rebleeding within 5 days, and ACLF are independent predictors of mortality.

Abstract
OBJECTIVE Gastric variceal bleeding is one of the most feared complications of portal hypertension and hence merits investigation for its optimal therapy. We aimed to evaluate the efficacy and long-term outcome(s) of patients treated with a single session of histoacryl sclerotherapy for active gastric variceal bleeding. METHODS The medical records of patients who presented with active gastric variceal bleeding between 1998 and 2011 in a tertiary care setting were evaluated retrospectively and the eventual outcome(s) (initial hemostasis, rebleeding, and mortality rate) was assessed at least 1 year after the index bleed. RESULTS Ninety-seven patients were included. The mean age of the patients was 51.0 ± 12.5 years; 62% were men. Hepatitis C was the most common etiology, found in 63 (65%) patients. The majority of the patients were classified as Child-Pugh grade B and C: 44 (46%) and 29 (31%) patients, respectively. A total of 40 (41%) patients were IGV1, 35 (36%) patients were GOV 2, 20 (21%) patients were GOV 1, and 2 (2%) patients were IGV2. A single session of histoacryl was successful in controlling bleeding in 83 (86%) patients. Seven (7%) patients died during the hospital stay. Rebleeding was observed in 24 (27%) patients during the 1-year follow-up, of whom 12 (50%) were managed successfully with repeated histoacryl injection. The overall mortality rate at 6 weeks, 6 months, and 1 year was 14 (14%), 19 (20%) and 26 (27%) patients, respectively. Child-Pugh classification was a significant prognostic factor of survival (P<0.001). CONCLUSION A single session of histoacryl sclerotherapy is effective in the majority of patients with active gastric variceal bleeding. Rebleeding was observed in one-fourth of patients, half of whom were controlled successfully by repeated histoacryl sclerotherapy.

Abstract
Variceal bleeding is one of the commonest and most severe complications of liver cirrhosis. Even with the current best medical care, mortality from variceal bleeding is still around 20%. When cirrhosis is diagnosed, varices are present in about 30-40% of compensated patients and in 60% of those who present with ascites. Once varices have been diagnosed, the overall incidence of variceal bleeding is in the order of 25% at two years. Variceal size is the most useful predictor for variceal bleeding, other predictors are severity of liver dysfunction (Child-Pugh classification) and the presence of red wale marks on the variceal wall. The current consensus is that every cirrhotic patient should be endoscopically screened for varices at the time of diagnosis to detect those requiring prophylactic treatment. Non-selective beta-adrenergic blockers (NSBB) and endoscopic band ligation (EBL) have been shown effective in the prevention of first variceal bleeding. The current recommendation for treating acute variceal bleeding is to start vasoactive drug therapy early (ideally during the transferral or to arrival to hospital, even if active bleeding is only suspected) and performing EBL. Once bleeding is controlled, combination therapy with NSBB + EBL should be used to prevent rebleeding. In patients at high risk of treatment failure despite of using this approach, an early covered-TIPS within 72 h (ideally 24 h) should be considered. Data on management of gastric variceal bleeding is limited. No clear recommendation for primary prophylaxis can be done. In acute cardiofundal variceal bleeding, vasoactive agents together with cyanoacrylate (CA) injection seem to be the treatment of choice. Further CA injections and/or NSBB may be used to prevent rebleeding. TIPS or Balloon-occluded retrograde transvenous obliteration when TIPS is contraindicated may be used as a rescue therapy.

Abstract
AIM: To compare the efficacy of modified percutaneous transhepatic variceal embolization (PTVE) with 2-octyl-cyanoacrylate (2-OCA) and endoscopic variceal obturation (EVO) with an injection of 2-OCA for prophylaxis of gastric variceal rebleeding.
METHODS: In this retrospective study, the medical records of liver cirrhosis patients with gastric variceal bleeding who underwent either endoscopic 2-OCA (EVO) or modified PTVE using 2-OCA at Shandong Provincial Hospital from January 2006 to December 2008 were reviewed. Patient demographics, rebleeding rate, survival rate, and complications were compared between the two groups (PTVE and EVO). All results were expressed as mean ± SD, or as a percentage. Quantitative variables were compared by two sample Student t tests, and qualitative variables were compared by the Fisher exact test or the χ2 test (with Yates correction) where appropriate. A P value less than 0.05 was considered significant. Statistical computation was performed using SPSS 13.0 software.
RESULTS: A total of 77 patients were included; 45 patients who underwent EVO and 32 patients who received PTVE. During the follow-up (19.78 ± 7.70 mo in the EVO group, vs 21.53 ± 8.56 mo in the PTVE group) rebleeding occurred in 17 patients in the EVO group and in 4 patients in the PTVE group (37.78% vs 12.5%, P = 0.028). The cumulative rebleeding-free rate was 75%, 59%, and 49% in 1, 2, and 3 years respectively for EVO, and 93%, 84%, and 84% for PTVE (P = 0.011). Cox analysis was used to identify independent factors that predicted rebleeding after treatment. Variables including age, gender, cause, Child-Pugh classification, size of gastric varices (GV), location of GV, and treatment methods were analyzed. It was revealed that Child-Pugh classification [risk ratio (RR) 2.10, 95%CI: 1.03-4.28, P = 0.040], choice of treatment (RR 0.25, 95%CI: 0.08-0.80, P = 0.019), and size of GV (RR 2.14, 95%CI: 1.07-4.28, P = 0.032) were the independent factors for predicting rebleeding. Follow-up computed tomography revealed that cyanoacrylate was retained in the varices and in the feeding veins of PTVE patients. During the follow-up, eight patients in the EVO group and four patients in the PTVE group died. The cumulative survival rates at 1, 2, and 3 years were 93%, 84%, and 67% respectively in the EVO group, and 97%, 88%, and 74% respectively in the PTVE group. The survival rates were not significantly different between the two groups (P = 0.432). Cox analysis showed that the Child-Pugh classification was the most significant prognostic factor of survival (RR 2.77, 95%CI: 1.12-6.80, P = 0.027). The incidence of complications was similar in both groups.
CONCLUSION: With extensive and permanent obliteration of gastric varices and its feeding veins, PTVE with 2-OCA is superior to endoscopic 2-OCA injection for preventing gastric variceal rebleeding.

Abstract
The skin adhesive Histoacryl(®) consists of n-butyl-2-cyanoacrylate which polymerises in contact with moisture. It is not fully biodegradable, produces heat during polymerisation and releases products which are toxic and inhibit cell growth. Clinical application is exclusively approved to glue skin. However, there are also clinical studies and case reports in the scientific literature, which discuss the application of Histoacryl(®) as a soft tissue adhesive. In parallel to an analysis of the literature which discusses the usage of Histoacryl(®) in head and neck surgery, we performed in vitro and in vivo investigations with this adhesive. In vitro, the vitality of cultured cell lines which where treated with extracts of Histoacryl(®) was determined with a viability assay. In addition, Histoacryl(®) was examined by fixing defined mucous membrane of the nasal septum in an animal study in rabbits. The analysis of the literature shows both positive and negative results for the application of Histoacryl(®) as a soft tissue adhesive depending on the manner and place of the application as well as the applied amount of glue. Our own results confirm a negative influence of Histoacryl(®) on the viability of cultured cells and soft tissue. The histological examination showed that a better biocompatibility is achieved if the glue is used in small amounts. Both the literature study as well as the in vitro and in vivo examinations showed that the usage of Histoacryl(®) as a soft tissue glue may be arguable. Critical factors are the moisture at the application area and the applied amount of glue.

Abstract
Background and aims: Our aim was to evaluate the utility of endoscopic obliterative therapy with Histoacryl for gastric varices and to investigate the incidence of serious complications. Methods: Endoscopic obliterative therapy with Histoacryl was performed on 129 gastric variceal patients. Sixty-five patients had cardiofornical varices, and 64 had fundal varices. Forty-five of 129 patients were emergency cases and the other 84 patients were prophylactic cases. Endoscopic therapy was performed under fluoroscopy using 70% Histoacryl (Histoacryl diluted with 5% Lipiodol). Results: Endoscopic hemostasis of gastric varices was successful in 45/45 (100%) emergency cases. The recurrence rate of gastric varices was 17/120 (14.2%) among patients whose variceal eradication was achieved. Additional treatment was successfully performed in all recurrent cases. The incidence of serious complications was 4/129 (3.1%), including two cases of splenic infarction, one case of pulmonary embolism, and one case of an inflammatory tumor of pancreatic tail. The two patients with splenic infarction improved with conservative medical treatment. The patient with pulmonary embolism showed no respiratory symptoms, and died of liver failure. The patient with the pancreatic tumor, which was diagnosed as an inflammatory tumor, was treated surgically. Conclusions: Endoscopic obliterative therapy with Histoacryl is a useful and relatively safe method for treatment of bleeding gastric varices. Nonetheless, careful attention must be paid to avoid potentially serious complications.

Abstract
BACKGROUND N-butyl-2-cyanoacrylate has been successfully used for the treatment of bleeding from gastric fundal varices (FV). However, significant rebleeding rates and serious complications including embolism have been reported. OBJECTIVE Our purpose was to analyze the safety and efficacy of N-butyl-2-cyanoacrylate for FV bleeding by using a standardized injection technique and regimen. DESIGN Retrospective. SETTING Two tertiary referral centers. PATIENTS A total of 131 patients (91 men/40 women) with FV underwent obliteration with N-butyl-2-cyanoacrylate by a standardized technique and regimen. INTERVENTIONS (1) Dilution of 0.5 mL of N-butyl-2-cyanoacrylate with 0.8 mL of Lipiodol, (2) limiting the volume of mixture to 1.0 mL per injection to minimize the risk of embolism, (3) repeating intravariceal injections of 1.0 mL each until hemostasis was achieved, (4) obliteration of all tributaries of the FV, (5) repeat endoscopy 4 days after the initial treatment to confirm complete obliteration of all visible varices and repeat N-butyl-2-cyanoacrylate injection if necessary to accomplish complete obliteration. MAIN OUTCOME MEASUREMENTS Immediate hemostasis rate, early rebleeding rate, bleeding-related mortality rate, procedure-related complications, long-term cumulative rebleeding-free rate, and cumulative survival rate. RESULTS Initial hemostasis and variceal obliteration were achieved in all patients. The mean number of sessions was 1 (range 1-3). The mean total volume of glue mixture used was 4.0 mL (range 1-13 mL). There was no occurrence of early FV rebleeding, procedure-related complications, or bleeding-related death. The cumulative rebleeding-free rate at 1, 3, and 5 years was 94.5%, 89.3%, and 82.9%, respectively. CONCLUSION Obliteration of bleeding FV with N-butyl-2-cyanoacrylate is safe and effective with use of a standardized injection technique and regimen.

Abstract
INTRODUCTION This was a prospective, randomised study undertaken from January 2001 to July 2003 firstly to assess the possibility of using glues to fix meshes, secondly to verify whether or not this leads to a higher hernia recurrence rate, and thirdly to assess post-operative pain. METHODS This study covered a total of 55 patients with bilateral hernias who presented similar characteristics on both sides and on whom fixation of the mesh was undertaken differently, depending on the side. On the right side polypropylene sutures were used (prolene 2/0), while on the left, attachment was done using glue (Tissucol). RESULTS AND CONCLUSIONS Results were similar in both inguinal regions, although there was less post-operative pain and less inflammatory reaction on the left side. There was no hernia recurrence in the follow-up at the end of 1 year.

Abstract
OBJECTIVES N-butyl-2-cyanoacrylate has been reported to be effective for bleeding varices but is not available in the United States. We report the initial US experience with cyanoacrylate in this prospective trial and evaluate its safety, efficacy, and relative costs. METHODS Patients with active or recent gastric variceal bleeding were eligible. Cyanoacrylate therapy was performed until variceal occlusion was achieved. Rebleeding was assessed at 72 h (acute phase), 6 wk (subacute phase), and 1 yr (chronic phase). Survival was assessed at 3 months and 1 yr. Cost analysis was performed comparing the first 17 patients to historical control patients not treated with cyanoacrylate. RESULTS A total of 44 patients were enrolled, 37 with cirrhosis and seven with noncirrhotic portal hypertension (NCPH). In cirrhotic patients, rebleeding was seen in two of 37 (5%) at 72 h, one of 30 (3%) at 6 wk, and five of 28 (18%) at 1 yr. Survival without shunt at 3 months was 30 of 34 (88%) and at 1 yr was 24 of 31 (77%). In NCPH patients, rebleeding was seen in two of seven (29%) at 72 h. These patients received definitive therapy for NCPH after diagnosis. Mortality and costs were substantially higher in the non-cyanoacrylate group. The odds of death were greater by 7-fold in the non-cyanoacrylate group than within the cyanoacrylate group (95% CI = 1.18-41.36, p = 0.0318). At 3 months, there was a 3.18-fold difference (95% CI = 1.05-9.64, p = 0.0411) in accrued costs; at 1 yr, the difference was 2.55-fold (95% CI = 0.96-6.94, p = 0.0585). The cost-effective ratio was estimated as 108,237 US dollars/death averted, reflecting marked cost reduction with improved survival in the cyanoacrylate-treated group. This is believed to result largely from avoidance of shunt interventions. CONCLUSIONS Cyanoacrylate treatment of gastric varices is safe, clinically effective, and cost effective.
