Endoscopic Vacuum Therapy for Upper Gastrointestinal Leaks and Perforations: Analysis From a Multicenter Spanish Registry.

INTRODUCTION: Endoscopic vacuum therapy (EVT) is a novel technique for closing upper gastrointestinal (UGI) defects. Available literature includes single-center retrospective cohort studies with small sample sizes. Furthermore, evidence about factors associated with EVT failure is scarce. We aimed to assess the efficacy and safety of EVT for the resolution of UGI defects in a multicenter study and to investigate the factors associated with EVT failure and in-hospital mortality. METHODS: This is a prospective cohort study in which consecutive EVT procedures for the treatment of UGI defects from 19 Spanish hospitals were recorded in the national registry between November 2018 and March 2022. RESULTS: We included 102 patients: 89 with anastomotic leaks and 13 with perforations. Closure of the defect was achieved in 84 cases (82%). A total of 6 patients (5.9%) had adverse events related to the EVT. The in-hospital mortality rate was 12.7%. A total of 6 patients (5.9%) died because of EVT failure and 1 case (0.9%) due to a fatal adverse event. Time from diagnosis of the defect to initiation of EVT was the only independent predictor for EVT failure (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.05, P = 0.005). EVT failure (OR 24.5, 95% CI 4.5-133, P = 0.001) and development of pneumonia after EVT (OR 246.97, 95% CI 11.15-5,472.58, P = 0.0001) were independent predictors of in-hospital mortality. DISCUSSION: EVT is safe and effective in cases of anastomotic leak and perforations of the upper digestive tract. The early use of EVT improves the efficacy of this technique.

A multicenter analysis of the role of prophylactic transfusion of blood products in patients with cirrhosis and esophageal varices undergoing endoscopic band ligation.

BACKGROUND & AIMS: Prophylactic administration of platelets and fresh frozen plasma (FFP) has been recommended in patients with cirrhosis with low platelets and/or prolonged international normalized ratio (INR) without scientific evidence to support this practice. In this analysis, we evaluated the use of prophylactic administration of blood products in outpatients with cirrhosis undergoing endoscopic band ligation (EBL). METHODS: This is a multicenter retrospective analysis of consecutive EBL procedures in patients with cirrhosis at 4 hospitals in Spain from 01/2010-01/2017. FFP and/or platelet transfusion were given at the discretion of the physician if INR was >1.5 and/or platelet count <50x109/L. Patient demographics, endoscopic findings, bleeding events after EBL, and the use of prophylactic FFP or platelets were recorded. RESULTS: A total of 536 patients underwent 1,472 EBL procedures: 72% male; main etiology HCV and alcohol (72%); median MELD score 11; Child-Pugh A/B/C (59/33/8%). EBL procedures were performed for primary (51%) or secondary (49%) prophylaxis. A median of 2 procedures per patient were performed.1-4 FFP and/or platelets were administered in 41 patients (7.6%). The prophylactic transfusion protocol was followed in 16% and 28% of procedures with high INR and/or low platelets, respectively. Post-EBL bleeding occurred in 26 out of 536 patients (4.8%) and in 33 out of 1,472 procedures (2.2%). Bleeding was due to post-EBL ulcers in 21 patients and due to band dislodgment in 5. In 6 patients, bleeding occurred within 24 hours and in the remaining patients it occurred within 2 weeks after EBL. In those that bled, 7 met criteria for transfusion (2 for FFP and 5 for platelets), of whom only 1 received FFP and 4 received platelets; the remaining 19 patients did not meet criteria for transfusion. There was no association between INR or platelet count and bleeding events. Univariate and multivariate analysis revealed that Child-Pugh and MELD scores were risk factors for post-EBL bleeding. CONCLUSIONS: The incidence of post-EBL bleeding is low and is associated with advanced liver disease. Post-EBL bleeding was not related to baseline INR/platelet count and most outpatients with post-EBL bleeding did not meet criteria for prophylactic transfusion. LAY SUMMARY: Patients with chronic liver disease or cirrhosis and enlarged veins (varices) of the esophagus that can potentially bleed commonly need an endoscopy to treat these varices with elastic rubber bands (endoscopic band ligation). Some patients have low platelet counts or prolonged coagulation tests. This analysis of 4 centers evaluated the use of prophylactic administration of blood products in outpatients with cirrhosis undergoing endoscopic band ligation. The results showed that bleeding after band ligation is uncommon and that if bleeding occurs it does not seem to be related with coagulation tests or the administration of blood products to prevent bleeding after band ligation of esophageal varices.

The presence and outcome of biliary sphincter disorders in liver-transplant recipients according to the Rome IV classification.

BACKGROUND: Biliary sphincter disorders after liver transplantation (LT) are poorly described. We aim to describe the presence and outcome of patients with papillary stenosis (PS) and functional biliary sphincter disorders (FBSDs) after LT according to the updated Rome IV criteria. METHODS: We reviewed all endoscopic retrograde cholangiopancreatographies (ERCPs) performed in LT recipients between January 2003 and December 2019. Information on clinical and endoscopic findings was obtained from electronic health records and endoscopy databases. Laboratory and clinical findings were collected at the time of ERCP and 1 month after ERCP. RESULTS: Among the 1,307 LT recipients, 336 underwent 849 ERCPs. Thirteen (1.0%) patients met the updated Rome IV criteria for PS [former sphincter of Oddi dysfunction (SOD) type I] and 14 patients (1.0%) met the Rome IV criteria for FBSD (former SOD type II). Biliary sphincterotomy was performed in 13 PS and 10 FBSD cases. One month after sphincterotomy, bilirubin, gamma-glutamyl transferase and alkaline phosphatase levels decreased in 85%, 61%, and 92% of those in the PS group (P = 0.019, 0.087, and 0.003, respectively) and in 50%, 70%, and 80% of those in the FBSD group (P = 0.721, 0.013, and 0.093, respectively). All the 14 patients initially suspected of having a FBSD turned out to have a different diagnosis during the follow-up. CONCLUSIONS: PS after LT is uncommon and occurs in only 1% of LT recipients. Our data do not support the presence of an FBSD after LT. Sphincterotomy is a safe and effective procedure in LT recipients with PS.

Endoscopic management of bile leaks after liver transplantation: An analysis of two high-volume transplant centers.

BACKGROUND: Bile leak after liver transplantation (LT) is commonly treated with endoscopic retrograde cholangiopancreatography (ERCP); however, there are limited data regarding the optimal treatment strategy. OBJECTIVE: We aimed to examine the role of ERCP in LT recipients with bile leaks at two large institutions. METHODS: We reviewed all ERCPs performed in LT recipients with bile leak and duct-to-duct biliary anastomosis at two high-volume transplant centers. RESULTS: Eighty patients were included. Forty-seven (59%) patients underwent ERCP with plastic stent placement (with or without sphincterotomy) and 33 patients (41%) underwent sphincterotomy alone. Complete resolution was obtained in 94% of the stent group vs. 58% of the sphincterotomy group (p < 0.01). There was no difference in three-month survival among both groups. Percutaneous transhepatic therapy and surgery were required in 4% and 6% in the stent group vs. 12% and 42% in the sphincterotomy group, respectively (p = 0.22 and p < 0.001). The only predictive factor of bile leak resolution was stent placement. CONCLUSION: ERCP with plastic stent placement is highly successful and more effective than sphincterotomy alone for post-LT bile leak treatment. These results indicate that ERCP and plastic stent placement should be considered the standard of care for the treatment of bile leaks in LT.

Weber-Christian disease with ileocolonic involvement successfully treated with infliximab.

Weber-Christian disease (WCD) is an inflammatory disease whose main histological feature is lobular panniculitis of adipose tissue. The location of panniculitis determines the clinical presentation, being the subcutaneous adipose tissue the most frequent one, followed by liver, spleen, bone marrow and mesenteric adipose tissue. Systemic corticosteroids are first line treatment, but other options should be considered if systemic symptoms are observed or in case of refractory clinical situation. We report herein a case with WCD showing orbital, mesenteric and ileocolonic involvement, which required surgical treatment and also developed postoperative recurrence. Symptoms were resolved by administration of thalidomide and, afterwards, infliximab. To our knowledge, this is the first report of Weber-Christian disease with luminal ileocolonic involvement, treated with infliximab.

Endoscopic band ligation and esophageal stents for acute variceal bleeding.

Patients with portal hypertension and esophageal varices are at risk of bleeding due to a progressive increase in portal pressure that may rupture the variceal wall. Appropriate treatment with initial general measures, such as resuscitation, a restrictive transfusion policy, antibiotic prophylaxis, pharmacologic therapy with vasoconstrictors, and endoscopic therapy with endoscopic band ligation are mandatory. However, 10% to 15% of patients fail initial endoscopic therapy and thus rescue therapies are needed. This article reviews the current endoscopic strategies with band ligation and esophageal stents for patients with acute variceal bleeding.

Endoscopic retrograde cholangiography for biliary anastomotic strictures after liver transplantation.

Biliary complications after liver transplantation (LT) are an important cause of morbidity and mortality. In most cases, an anastomosis of the bile duct is performed as a duct-to-duct reconstruction, which makes endoscopic therapy with endoscopic retrograde cholangiography (ERC) feasible. Biliary anastomotic strictures (AS) are the most common cause of biliary complications. The early detection of an AS, which can sometimes be challenging given that its clinical presentation is often subtle, is of key importance to obtain high treatment success. In this review, we focus on the management of AS after LT with a special emphasis on ERC.
