Long-term outcomes of endoscopic ultrasound-guided hepaticogastrostomy in patients with malignant biliary obstruction.

BACKGROUND: Hepaticogastrostomy drainage through endoscopic ultrasound (EUS-HGS) has emerged in the 2010s as a new technique for biliary decompression in cases of endoscopic retrograde cholangiopancreatography (ERCP) failure for malignant biliary obstruction (MBO). Substantial technical and procedural progress in performing EUS-HGS has been achieved, allowing high technical and clinical success and an acceptable risk of adverse events in studies mainly focusing on short-term outcomes. However, the long-term effects of EUS-HGS and the risk of recurrent biliary obstruction (RBO) have not been fully evaluated. OBJECTIVES: To evaluate the long-term effects of EUS-HGS and the risk of RBO. METHODS: Data from 211 patients undergoing technically successful EUS-HGS in three academic centers were retrospectively collected. Clinical success, adverse events, RBO, and reinterventions were evaluated. RESULTS: In total, 198 patients underwent technically successful EUS-HGS for MBO. The median overall survival was 144 days [108, 2011] after the procedure. Mean patient age was 69.39 (12.91) years. The cause of MBO was pancreatic cancer (n = 98, 49.5%) followed by cholangiocarcinoma (n = 29, 14.6%). The location of MBO was distal in 27.6% of cases and proximal in 68.4%. Adverse events were observed during the follow-up in 65 patients (33%). On multivariate analysis, the use of partially covered self-expandable metal stents (PCSEMS) was associated with a lower risk of RBO (HR = 0.47 [0.24-0.95], p = 0.034). Additionally, patients with distal stenoses had a trend toward better stent patency (HR = 0.06[0-0.77], p = 0.031). RBO developed in 38 cases (19.1%) mainly due tumor ingrowth (36.8%) with a high success rate of endoscopic management. CONCLUSIONS: While RBO occurred in a notable proportion of patients, the primary cause of mortality was progression of the underlying malignancy rather than stent dysfunction. The efficiency of stents, particularly PCSEMS, and the high success rate of endoscopic management for RBO underscore the effectiveness and reliability of these treatments in managing biliary complications.

Outcomes and predictors of delayed endoscopic biliary drainage for severe acute cholangitis due to choledocholithiasis in an intensive care unit.

BACKGROUND: Acute cholangitis (AC) is an infection of the biliary tract secondary to biliary obstruction requiring biliary drainage through endoscopic retrograde cholangiopancreatography. This study aims to compare the outcome between the early and delayed ERCP in patients with severe AC. METHODS: Patient with severe AC due to choledocholithiasis admitted to intensive care unit were included. Early ERCP was defined was as ERCP performed within 24 h following hospital admission. Propensity-score matching was used to reduce the imbalance between groups. The primary outcome was 30-day mortality. Secondary outcomes included length of hospital and ICU stay, onset or persistent organ failure. RESULTS: The delayed ERCP group had a higher mortality rate at 30 days (45,5 versus 13%, <0.001) and at 1 year (59,7% versus 15,6%, p <0.001). Delayed ERCP had also a higher rate of respiratory adverse events (54,5 versus 27,8%, p = 0,002), longer ICU (7.41 versus 4.61, p = 0,004) and hospital (11,88 versus 9,22, p = 0,042) length of stay. Predictors of delayed ERCP were cardiac arrythmias, liver disease, creatinine value and white blood cell count at baseline. CONCLUSIONS: Delays in ERCP for patients with severe AC appear to be associated with higher mortality rate and prolonged ICU and hospital stays.

Single-use duodenoscopes are an efficient tool for emergency ERCP in real life.

Background Biliary tract emergencies are managed with endoscopic retrograde cholangiopancreatography (ERCP) using duodenoscopes, which are reusable devices that require high-level disinfection to minimize risk of cross-contamination. Recent reports about newly developed single-use duodenoscopes (SUDs) suggest equivalent performance with reusable duodenoscopes, but the effectiveness of SUDs in emergency ERCP has not yet been studied. Patients and methods We conducted a prospective case series of emergency ERCP procedures using SUDs (EXALT model D-Boston Scientific, United States) in a real-life, tertiary care setting without any possibility of using a back-up reusable duodenoscope. Results Twenty-one emergent ERCPs (acute cholangitis 48%, severe jaundice 38 %, others 14 %) were performed in 19 patients (mean age 49.5±15 years). Almost all procedures (20 of 21; 95 %) were technically and clinically successful, whereas selective cannulation failed in one case. Among the successful ERCPs, five (24 %) were achieved by a novice operator. The image was often considered skewed toward yellow tones (48 %), whereas stiffness and pushability for stent insertion were found suboptimal in 5 % of the procedures, without any impact on procedure success. Conclusions SUDs are effective and appropriate devices for emergent situations in real life even in non-expert hands and even if a regular duodenoscope is unavailable as a backup.

Does endoscopic mean safer? A comparison of the short-term safety of endoscopic versus laparoscopic bariatric therapies.

Background and study aims There is minimal research on real-world, large-volume data comparing endoscopic bariatric therapy (EBT) to laparoscopic bariatric therapy (LBT). This study aimed to compare 30-day postoperative morbidity and mortality outcomes of primary EBT vs LBT using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. Patients and methods Patients aged 18 to 80 with body mass index (BMI) 35 to 40 kg/m 2 undergoing primary procedures were included. Propensity score matching 1:50 was performed for EBT versus LBT based on age, sex, and BMI. Results We matched 211 EBTs with 9,059 LBTs. Operative length (63.9, 95 % confidence interval [CI]: 57.9, 69.8 versus 81.1, 95 % CI: 80.1, 82.1) and length of stay (0.49 days, 95 % CI: 0.29, 0.69 versus 1.43 days, 95 % CI: 1.41, 1.45) were significantly lower in the EBT group than the LBT group. There was no difference between EBT and LBT in the odds of readmission (odds ratio [OR] = 0.31, 95 % CI: 0.08, 1.25), reoperation (OR = 0.39, 95 % CI: 0.05, 2.84), or reintervention (OR = 0.98, 95 % CI: 0.24, 3.99). After controlling for chronic obstructive pulmonary disease, sleep apnea, history of myocardial infarction, hypertension requiring medications, and diabetes, EBT continued to be associated with lower odds of having any adverse event (AE) than LBT, with an OR of 0.34 (95 % CI: 0.16, 0.69). Subgroup analysis comparing EBT to laparoscopic sleeve gastrectomy (LSG) showed that EBT was associated with a lower risk having any AE than LSG, with an OR of 0.39 (95 % CI: 0.19, 0.79). Conclusions EBT is associated with a lower 30-day AE rate and shorter procedural length and length of stay than LBT, with similar rates of readmission, reintervention, and reoperation.

Analysis of spontaneous labor progression of breech presentation at term.

BACKGROUND: Cervical dilatation curves are widely used to describe normal and abnormal labor progression for cephalic presentation. Labor curves for breech presentations have never been described. OBJECTIVES: The aims of this study were to examine the pattern of labor progression in women with a breech presentation and to determine whether the type of breech or parity can influence the speed of cervical dilatation. STUDY DESIGN: We analyzed the labor data from 349 women with a term, singleton, and breech fetus after spontaneous onset of labor in 2010-2018. Cesarean deliveries were excluded. The patterns of labor progression were described by examining the relationship between the elapsed times from the full dilatation and cervical dilatation stages. Average labor curves were developed using repeated-measures analysis with 3rd degree polynomial modeling. The results were interpreted according to parity and the type of breech. RESULTS: The first stage of labor progression was divided into a latency phase from 0 to 5 cm of dilatation and an active phase from 5 to 10 cm. In the active phase, the median speed of cervical dilatation was 1.67 cm/h [1.25, 2.61] (2 cm/h for multipara and 1.54 cm/h for nullipara). The difference by parity was significant in the active phase (p< 0.05). The cervical dilatation rate from 3 cm to 10 cm did not significantly differ between the complete and frank breeches (1.56 cm/h vs 1.75 cm/h, p = 0.48). However, the median cervical dilatation rate from 8 cm to complete dilatation was faster for complete breeches (1.92 cm/h versus 1.33 cm/h, p = 0.045). CONCLUSION: As with cephalic presentation, the first stage of labor progression for breech presentation can be divided into a latent and active phase. Labor progression should be interpreted with respect to parity, and women should be informed that the type of breech does not seem to influence the cervical dilatation rate when there is adequate management.

The Attitude of Practitioners Towards Endoscopic Sleeve Gastroplasty.

BACKGROUND AND AIM: Despite widespread adoption and encouraging results seen over the last 5 years, no consensus exists regarding the endoscopic sleeve gastroplasty (ESG) technique, training, or preprocedure and postprocedure management of the patient. The aim of our survey was to assess practice trends and preferences of bariatric endoscopists with respect to ESG. METHODS: Using a digital platform, we conducted a worldwide survey by emailing a link with an electronic questionnaire to 1200 bariatric endoscopists trained to perform endoscopic suturing using the Apollo Overstitch suturing device (Apollo Endosurgery). RESULTS: We received 221 responses that were included in the analysis. Fifty-one responders (36.4%) required 1 to 10 procedures, and 37 (26.4%) needed 11 to 20 procedures to become proficient at ESG. Ninety-six (68.6%) stated that lower body mass index thresholds should be adopted for Asian and Arab patients. There was no consensus on the ideal number of sutures, with 45 (32.1%), 42 (30%), 36 (25.7%), 13 (9.3%), and 4 (2.9%) recommending 4 to 6, 5 to 7, 6 to 8, 7 to 9, and 8 to 12 sutures, respectively. The primary barriers to establishing an endobariatric program were the inability to establish a cash pay model, 77 (95.1%); lack of institutional support, 61 (75.3%); and difficulty in establishing an ambulatory surgical center/hospital to perform ESG, 73 (90.1%). CONCLUSIONS: ESG practice trends remain heterogenous among practitioners in regard to indication, technique, and preprocedure and postprocedure management. Specific ESG guidelines are warranted, and this survey will assist in providing the framework for these guidelines to be written.

Serum phosphate is associated with mortality among patients admitted to ICU for acute pancreatitis.

BACKGROUND AND AIMS: Routine laboratory tests can be useful predictors in the early assessment of the severity and mortality of acute pancreatitis (AP). The aim of this study was to evaluate the accuracy of clinical and laboratory parameters for the prediction of mortality among patients admitted to the intensive care unit (ICU) for AP. METHODS: We conducted a retrospective analysis of prospectively collected data from Beth Israel Deaconess Hospital made publicly available to examine the relationship between routine clinical and laboratory parameters with respect to mortality for AP. Cox proportional hazard ratio was used to evaluate the impact of several routine laboratory markers on mortality. Receiver operation characteristic (ROC) curve was performed to determine the accuracy of diagnosis of laboratory tests by using area under curve (AUC) for the respective analysis. RESULTS: In total, 499 patients were admitted to the ICU for AP. Several factors for predicting mortality in AP at admission were identified in the multivariate analysis: alkaline phosphatase hazard ratio (HR) = 1.00 (1.00-1.00, p = 0.024), anion gap HR = 1.09 (1.00-1.20, p = 0.047), bilirubin total HR = 1.11 (1.06-1.17, p < 0.001), calcium total HR = 0.59 (0.42-0.84, p = 0.004), phosphate HR = 1.51 (1.18-1.94, p = 0.001), potassium HR = 1.91 (1.03-3.55, p = 0.041), white blood cells HR = 1.04 (1.00-1.07, p = 0.028). The AUC of serum phosphate level for mortality was 0.7 in the ROC analysis. The optimal cut-off value of serum phosphate level for prediction of mortality was 3.78 mg/dl (sensitivity, 0.58; specificity, 0.78). CONCLUSION: In this large cohort, we identified baseline serum phosphate as the most valuable single routine laboratory test for predicting mortality in AP. Future prospective studies are required to confirm these results.

The Utility of EndoFLIP for Measuring Gastrojejunal Anastomosis Diameter and Distensibility in Patients Experiencing Weight Regain Post Roux-en-Y Gastric Bypass.

A dilated gastrojejunal anastomosis (GJA) diameter is an independent predictor of weight regain following Roux-en-Y gastric bypass (RYGB). Despite this, there is no standardized method for GJA diameter measurement. We performed a retrospective analysis to compare endoscopic visual estimation and endoluminal functional impedance planimetry (EndoFLIP) for measuring GJA diameter in patients with weight regain post-RYGB. Visual estimation was found to overestimate GJA diameter by a mean of 4.2mm ± 4.6mm when compared with EndoFLIP. Furthermore, we identified symptomatic patients with normal GJA diameter but increased distensibility, which may represent a previously unrecognized subgroup. Our findings suggest the potential utility of EndoFLIP in the evaluation of post-RYGB weight regain and support the need for prospective studies to investigate the relationship between GJA distensibility and weight regain.

Endoscopic sleeve gastroplasty: suturing the gastric fundus does not confer benefit.

BACKGROUND : There is heterogeneity regarding the technical aspects of endoscopic sleeve gastroplasty (ESG), such as applying fundal sutures. Our aim was to determine whether ESG with fundal suturing (ESG-FS) affects weight loss and the serious adverse event (SAE) rate when compared with ESG with no fundal suturing (ESG-NFS). METHODS: We conducted a two-center retrospective analysis of 247 patients who underwent ESG with or without fundal suturing. The primary outcome was percentage excess weight loss (%EWL) at 3, 6, and 12 months post-ESG. The secondary outcomes included the SAE rate and procedure duration. RESULTS: At 3, 6, and 12-months, ESG-NFS had a significantly greater mean %EWL compared with ESG-FS (38.4 % [standard deviation (SD) 15.3 %] vs. 31.2 % [SD 13.9 %], P = 0.001; 54.7 % [SD 19.2 %] vs. 37.7 % [SD 17.3 %], P < 0.001; 65.3 % [SD 21.1 %] vs. 40.6 % [SD 23.5 %], P < 0.001, respectively). There was no statistically significant difference in the SAE rates for ESG-NFS (n = 2; 2.0 %) and ESG-FS (n = 4; 2.6 %; P > 0.99). The mean procedure time was significantly shorter in the ESG-NFS group at 59.1 minutes (SD 32.7) vs. 93.0 minutes (35.5; P < 0.001), and a lower mean number of sutures were used, with 5.7 (SD 1.1) vs. 8.4 (SD 1.6; P < 0.001). CONCLUSION : ESG-NFS demonstrated greater efficacy and shorter procedure duration. Therefore, fundal suturing should not be performed.

Safety of different electrocautery modes for endoscopic sphincterotomy: a Bayesian network meta-analysis.

BACKGROUND AND AIMS: Post-endoscopic retrograde cholangiopancreatography acute pancreatitis (PAP) and post-sphincterotomy hemorrhage are known adverse events of post-endoscopic retrograde cholangiopancreatography. Various electrosurgical currents can be used for endoscopic sphincterotomy. The extent to which this influences adverse events remains unclear. We assessed the comparative safety of different electrosurgical currents, through a Bayesian network meta-analysis of published studies merging direct and indirect comparison of trials. METHODS: We performed a Bayesian random-effects network meta-analysis of randomized controlled trials that compared the safety of different electrocautery modes for endoscopic sphincterotomy. RESULTS: Nine studies comparing four electrocautery modes (blended cut, pure cut, endocut, and pure cut followed by blended cut) with a combined enrollment of 1615 patients were included. The pooled results of the network meta-analysis did not show a significant difference in preventing post-sphincterotomy pancreatitis when comparing electrocautery modes. However, pure cut was associated with a statistically significant increased risk of bleeding compared with endocut [relative risk = 4.30; 95% confidence interval (1.53-12.87)]. On the other hand, the pooled results of the network meta-analysis showed no significant difference in prevention of bleeding when comparing blended cut versus endocut, pure cut followed by blended cut versus endocut, pure cut followed by blended cut versus blended cut, pure cut versus blended cut, and pure cut versus pure cut followed by blended cut. The results of rank probability found that endocut was most likely to be ranked the best. CONCLUSION: No electrocautery mode was superior to another with regard to preventing PAP. Endocut was superior with respect to preventing bleeding. Therefore, we suggest performing endoscopic sphincterotomy with endocut.

Efficacy of Liraglutide to Prevent Weight Regain After Retrieval of an Adjustable Intra-gastric Balloon-a Case-Matched Study.

PURPOSE: Weight regain after balloon retrieval is a concern with all intra-gastric balloons (IGBs). The aim of this study was to evaluate the efficacy of liraglutide, a glucagon-like peptide-1 (GLP-1) agonist, to prevent weight regain following IGB retrieval. MATERIALS AND METHODS: This was a case-matched study of patients undergoing Spatz3 adjustable IGB (Spatz FGIA, Inc. NY, USA) at three outpatient clinics in Brazil between November 2015 and January 2019. Seventy-seven patients that opted to take liraglutide following IGB retrieval (IGB-L) were matched 1:1 to 198 patients that declined the medication-IGB-Alone (IGB-A). Propensity score adjustment was performed at the time of balloon retrieval on factors known to influence the choice of liraglutide. Weight and percent body fat (%BF) was measured at baseline and 9 months after IGB retrieval. % BF is defined as the total mass of fat divided by total body mass, multiplied by 100. The primary outcome was weight regain, and the secondary outcome was change in %BF 9 months after IGB retrieval. RESULTS: Propensity score matching yielded 53 matched pairs. Weight regain to the starting point was not observed in either group. There was significantly less weight regain in IGB-L compared to IGB-A, - 1.15 ± 0.94 kg versus - 0.66 ± 0.99 kg (p = 0.010) 9 months after balloon retrieval. Additionally, %BF decline in IGB-L was superior to IGB-A - 10.83 ± 1.50 versus - 7.94 ± 2.02 (p < 0.01). There was no difference in weight regain or decline in %BF based on liraglutide dose. CONCLUSION: Liraglutide has an additive benefit with respect to efficacy and a reduction in body fat when commenced after IGB retrieval. Future randomized control studies will be needed to determine the optimal dose and duration of liraglutide to achieve superior outcomes.

Endoscopic sleeve gastroplasty plus liraglutide versus endoscopic sleeve gastroplasty alone for weight loss.

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) has been shown to be effective for inducing weight loss. The efficacy of liraglutide, a glucagon-like peptide-1 agonist, to augment weight loss after ESG is unknown. This study aims to evaluate the efficacy of ESG and liraglutide (ESG-L) compared with ESG alone. METHODS: This was a retrospective study of prospectively collected data from patients undergoing ESG at 3 outpatient clinics in Brazil between November 2017 and July 2018. Liraglutide was offered to all patients 5 months after ESG. Patients who opted to take liraglutide (ESG-L) were matched 1:1 to patients who declined it (ESG). The primary outcome was percent total body weight loss (%TBWL), and percent excess weight loss (%EWL) 7 months after initiation of liraglutide (12 months after ESG). The secondary outcome was change in percent body fat 12 months after ESG. ESG technique and postprocedure follow-up were identical at all 3 sites. RESULTS: Propensity score matching yielded 26 matched pairs. Adjusted comparisons between the 2 groups showed that patients who opted to take liraglutide had a superior mean %TBWL 7 months after initiation of liraglutide (ESG-L) compared with those who declined it (ESG) (24.72% ± 2.12% vs 20.51% ± 1.68%, respectively; P < .001). ESG-L had a statistically greater reduction in percent body fat compared with ESG (7.85% ± 1.26% vs 10.54% ± 1.88%, respectively; P < .001) at 12 months. CONCLUSIONS: Addition of liraglutide at 5 months results in superior weight loss and improved efficacy as demonstrated by decreased body fat 12 months after ESG. Further studies are imperative to determine optimal dose, timing, and duration of liraglutide.

Efficacy of gastric electrical stimulation in intractable nausea and vomiting at 10 years: A retrospective analysis of prospectively collected data.

BACKGROUND: Gastric electrical simulation has been shown to relieve nausea and vomiting in medically refractory patients. Efficacy of gastric electrical stimulation has been reported mostly in short-term studies, but none has evaluated its efficacy beyond 10 years after implantation. METHODS: Patients implanted at our center for medically refractory severe and chronic nausea and/or vomiting were evaluated before and over 10 years after implantation using symptomatic scale and quality of life (GIQLI) score. Improvement was defined as a reduction of more than 50% in vomiting frequency. KEY RESULTS: A total of 50 patients were implanted from January 1998 to December 2009. Among them, 7 were explanted due to a lack of efficacy and/or side effects, 2 died, and 4 were lost to follow-up. Mean follow-up was 10.5 ± 3.7 years. In intention-to-treat analysis, 27/50 (54%) patients reported an improvement. Beyond 10 years, an improvement in early satiety (3.05 vs 1.76, <0.001), bloating (2.51 vs 1.70, P = .012), nausea (2.46 vs 1.35, P = .001), and vomiting (3.35 vs 1.49 P < .001) scores were observed. Quality of life improved over 10 years (GIQLI score: 69.7 vs. 86.4, P = .005) and body mass index (BMI: 23.4 vs. 26.2 kg/m2 ; P = .048). CONCLUSIONS AND INFERENCES: Gastric electrical simulation is effective in the long-term in patients with medically refractory nausea and vomiting, with an efficacy of 54% at 10 years on an intention-to-treat analysis. Other long-term observational studies are warranted to confirm these results.

Building an endobariatric program: lessons learned.

The emphasis on treating obesity has never been more critical, yet the complexity of delivering care has become more intricate due to new procedures, variable insurance coverage, and inconsistent reimbursement. This is our experience building an endobariatric program and treating overweight and obese patients with endobariatric therapies (EBTs) over 3 years. The primary intention of this manuscript was to educate the reader on how to build an endobariatric program, identify barriers, and provide succinct solutions to establish a successful program. The secondary aim was weight loss outcomes of procedures offered at our institution. We compiled a list of lessons learned, based on the difficulties we experienced to make it easy for others embarking on this journey. Herein, we present a business development strategy to overcome impediments, whilst offering high quality service. The high cost and lack of insurance coverage are significant barriers. Marketing can be costly and is often a factor that is ignored particularly early on, when finances are limited. However, it is an integral component of growing the program. The percentage total body weight loss (%TBWL) at 6 and 12 months post ESG was 17.8 ±â€Š6.48 and 20.6 ±â€Š8.3 ( P  < 0.001), respectively. The %TBWL at 6 months post IGB was 14.9 ±â€Š9.8 for the Orbera IGB and 12.6 ±â€Š7.4 for the Reshape IGB. There was a trend of preference for ESG compared to IGB placement over the 3 years. The key to building a successful endobariatric program is a motivated physician leader, collaborative bariatric surgeons, institutional support, and marketing. Insurance coverage will likely occur in the near future and programs must be prepared to manage the massive influx of patients that will likely request these procedures.
