Dementia Frequently Coexists With Hepatic Encephalopathy but Not Other Cirrhosis Complications in US Veterans.

INTRODUCTION: Hepatic encephalopathy (HE) is a common decompensating event in patients with cirrhosis. Because of the aging population of patients with cirrhosis, differentiating HE from nonhepatic etiologies of cognitive impairment, such as dementia, is increasingly important. METHODS: Veterans with cirrhosis were identified via International Classification of Diseases -10 codes between October 1, 2019, and September 30, 2021, using the VA Corporate Data Warehouse. Baseline characteristics were compared between cohorts based on the presence vs absence of dementia. Factors associated with having a diagnosis of dementia were evaluated using multivariate logistic regression models, adjusting for demographics, comorbid illnesses, cirrhosis etiology, and cirrhosis complications. RESULTS: A total of 71,552 veterans with cirrhosis were identified, of which, 5,647 (7.89%) veterans had a diagnosis of dementia. Veterans with dementia were older, more frequently White, urban located, and diagnosed with alcohol-related cirrhosis, metabolic syndrome, brain trauma, and cerebrovascular disease more frequently. On multivariable analysis, the presence of any decompensating event was associated with dementia. Multivariable analysis of individual decompensating events revealed HE to be associated with a dementia diagnosis, but not ascites, independent of other risk factors analyzed. DISCUSSION: Dementia is commonly diagnosed in patients with cirrhosis and correlates with a diagnosis of HE, independent of alcohol use, brain injury, age, and other metabolic risk factors. Dementia did not correlate with other decompensating events. Increased awareness of the overlap between dementia and HE, as well as reliable diagnostic and treatment strategies, is needed for the aging population of veterans with cirrhosis.

Alcohol treatment discussions and clinical outcomes among patients with alcohol-related cirrhosis.

BACKGROUND: Alcohol cessation is the cornerstone of treatment for alcohol-related cirrhosis. This study evaluated associations between medical conversations about alcohol use disorder (AUD) treatment, AUD treatment engagement, and mortality. METHODS: This retrospective cohort study included all patients with ICD-10 diagnosis codes for cirrhosis and AUD who were engaged in hepatology care in a single healthcare system in 2015. Baseline demographic, medical, liver disease, and AUD treatment data were assessed. AUD treatment discussions and initiation, alcohol cessation, and subsequent 5-year mortality were collected. Multivariable models were used to assess the factors associated with subsequent AUD treatment and 5-year mortality. RESULTS: Among 436 patients with cirrhosis due to alcohol, 65 patients (15%) received AUD treatment at baseline, including 48 (11%) receiving behavioral therapy alone, 11 (2%) receiving pharmacotherapy alone, and 6 (1%) receiving both. Over the first year after a baseline hepatology visit, 37 patients engaged in AUD treatment, 51 were retained in treatment, and 14 stopped treatment. Thirty percent of patients had hepatology-documented AUD treatment recommendations and 26% had primary care-documented AUD treatment recommendations. Most hepatology (86%) and primary care (88%) recommendations discussed behavioral therapy alone. Among patients with ongoing alcohol use at baseline, AUD treatment one year later was significantly, independently associated with AUD treatment discussions with hepatology (adjusted odds ratio (aOR): 3.23, 95% confidence interval (CI): 1.58, 6.89) or primary care (aOR: 2.95; 95% CI: 1.44, 6.15) and negatively associated with having Medicaid insurance (aOR: 0.43, 95% CI: 0.18, 0.93). When treatment was discussed in both settings, high rates of treatment ensued (aOR: 10.72, 95% CI: 3.89, 33.52). Over a 5-year follow-up period, 152 (35%) patients died. Ongoing alcohol use, age, hepatic decompensation, and hepatocellular carcinoma were significantly associated with mortality in the final survival model. CONCLUSION: AUD treatment discussions were documented in less than half of hepatology and primary care encounters in patients with alcohol-related cirrhosis, though such discussions were significantly associated with receipt of AUD treatment.

Long-term Outcome of Gastric Per-Oral Endoscopic Pyloromyotomy in Treatment of Gastroparesis.

BACKGROUND & AIMS: Gastric per oral endoscopic pyloromyotomy (GPOEM) is a promising treatment for gastroparesis. There are few data on the long-term outcomes of this procedure. We investigated long-term outcomes of GPOEM treatment of patients with refractory gastroparesis. METHODS: We conducted a retrospective case-series study of all patients who underwent GPOEM for refractory gastroparesis at a single center (n = 97), from June 2015 through March 2019; 90 patients had more than 3 months follow-up data and were included in our final analysis. We collected data on gastroparesis cardinal symptom index (GCSI) scores (measurements of postprandial fullness or early satiety, nausea and vomiting, and bloating) and SF-36 questionnaire scores (measures quality of life). The primary outcome was clinical response to GPOEM, defined as a decrease of at least 1 point in the average total GCSI score with more than a 25% decrease in at least 2 subscales of cardinal symptoms. Recurrence was defined as a return to baseline GCSI or GCSI scores of 3 or more for at least 2 months after an initial complete response. The secondary outcome was the factors that predict GPOEM failure (no response or gastroparesis recurrence within 6 months). RESULTS: At initial follow-up (3 to 6 months after GPOEM), 73 patients (81.1%) had a clinical response and significant increases in SF-36 questionnaire scores (indicating increased quality of life) whereas 17 patients (18.9%) had no response. Six months after GPOEM, 7.1% had recurrence. At 12 months, 8.3% of patients remaining in the study had recurrence. At 24 months, 4.8% of patients remaining in the study had a recurrence. At 36 months, 14.3% of patients remaining in the study had recurrence. For patients who experienced an initial clinical response, the rate of loss of that response per year was 12.9%. In the univariate and multivariate regression analysis, a longer duration of gastroparesis reduced the odds of response to GPOEM (odds ratio [OR], 0.092; 95% CI, 1.04-1.3; P = .001). On multivariate logistic regression, patients with high BMIs had increased odds of GPOEM failure (OR, 1.097; 95% CI, 1.022-1.176; P = .010) and patients receiving psychiatric medications had a higher risk of GPOEM failure (OR, 1.33; 95% CI, 0.110-1.008; P = .052). CONCLUSIONS: In retrospective analysis of 90 patients who underwent GPOEM for refractory gastroparesis, 81.1% had a clinical response at initial follow-up of their procedure. 1 year after GPOEM, 69.1% of all patients had a clinical response and 85.2% of initial responders maintained a clinical response. Patients maintained a clinical response and improved quality of life for as long as 3 years after the procedure. High BMI and long duration gastroparesis were associated with failure of GPOEM.

Short-term outcomes of double versus single pyloromyotomy at peroral endoscopic pyloromyotomy in the treatment of gastroparesis (with video).

BACKGROUND AND AIMS: The prevalence of gastroparesis (Gp), a chronic debilitating disorder, and resulting hospitalizations are increasing. Gastric peroral endoscopic pyloromyotomy (POP or GPOEM) is a novel technique in the treatment of refractory Gp. Despite the initial promising results of GPOEM, one-third of patients do not exhibit any clinical response. Furthermore, loss of clinical response was reported in several studies. No response or loss of response after GPOEM may be related to inadequate myotomy. The aim of our study is to examine whether double pyloromyotomy at GPOEM is superior to single pyloromyotomy. METHOD: A retrospective case-controlled study of patients who underwent GPOEM for refractory Gp at our tertiary care institution between June 2015 and March 2018 was performed. Because the follow-up time for the single myotomy group was much longer than that of the double myotomy group, we matched the length of follow-up for the single myotomy group to that of the double myotomy group. The outcomes were measured by the changes in the Gastroparesis Cardinal Symptom Index (GCSI) before and 3 to 6 months after the procedure. Adverse events and other procedural and clinical parameters were also compared. RESULTS: Ninety patients underwent GPOEM (55 single and 35 double pyloromyotomy). The mean age was 47 ± 14 years, and the mean duration of symptoms was 5.3 ± 4.4 years. The average GCSI score was 3.8 before the GPOEM, and the average GCSI score 6 months after procedure was 1.8. Thirty-seven of 55 (67%) patients who underwent single pyloromyotomy achieved clinical response compared with 30 of 35 (86%) patients who underwent double pyloromyotomy. There were no significant differences for procedure time, postoperative pain, or length of hospital stay between the 2 groups. There was no difference in adverse events in the 2 pyloromyotomy groups. CONCLUSION: Double pyloromyotomy is a safe and feasible technique during GPOEM. Clinical success was higher in patients undergoing double pyloromyotomy compared with single pyloromyotomy in this nonrandomized, short-term follow-up study. Long-term studies are needed to further confirm our results.

Safety and Efficacy of TIPS as a Bridge to Liver Transplantation in Two Cases of Severely High MELD Patients With Variceal Bleeding.

Transjugular intrahepatic portosystemic shunt (TIPS) is well established as a salvage therapy for refractory esophageal variceal hemorrhage (EVH). A more controversial issue is the upper limit of Model for End-Stage Liver Disease (MELD) scores at which this procedure can be performed safely. We present 2 cases of TIPS performed for EVH in patients with severely high MELD scores as a successful intervention for hemostatic and hemodynamic stabilization, and as a bridge to urgent liver transplantation. Both patients had endoscopically confirmed EVH with high blood product transfusion and vasopressor needs despite standard medical therapy. Each received narrow bore TIPS at MELD 42 and 44, respectively, with subsequent resolution of hemorrhage despite worsening synthetic liver function. Detrimental consequences of metabolic acidosis associated with minimal residual hepatic function were avoided via continuous renal replacement therapy and mechanical ventilation, with a goal to maintain cardiopulmonary stability and favorable acid base balance. Liver transplant followed TIPS 4 and 3 days, respectively, with both patients maintaining good functional status at discharge. Both cases suggest that in patients deemed otherwise appropriate for liver transplantation, a severely high MELD score alone should not preclude TIPS as salvage therapy for refractory EVH bleeds.

Long-term Outcome of Per-oral Endoscopic Myotomy Performed in the Endoscopy Unit With Trainees.

INTRODUCTION: Per-oral endoscopic myotomy (POEM) has been widely adopted for the treatment of achalasia as it provides a precise, tailored myotomy in a minimally invasive endoscopic procedure. Several short-term studies and a few long-term studies have confirmed that POEM is a safe and effective treatment for achalasia. However, the long-term outcome of POEM performed by trainees is unknown. MATERIALS AND METHODS: We conducted a retrospective study of all patients who underwent POEM for achalasia at our tertiary care center during December 2012 and January 2019. All procedures performed with trainees were included. The primary outcome was the clinical response to POEM, defined as an Eckardt score of <3 after POEM. Trainees were trained in performing mucosotomy and submucosal dissection, creating a submucosal tunnel, identifying gastroesophageal junction, and performing myotomy and closure of mucosal incision in a step-by-step fashion. Trainees' performance was evaluated by the mentor based on several key points in each step. RESULTS: A total of 153 consecutive patients with a median age of 57±18 years were analyzed in this study. Of the total patients, 69 (45%) were male. The median length of follow-up after POEM was 32 months (range: 7 to 77 mo). A clinically significant response to POEM was achieved in 95% of patients at year 1, 84% at year 2, 80% at year 3, 79% at year 4, 78% at year 5, and 78% at year 6 and above. All trainees obtained competence within 6 cases for each step and could perform the procedure alone after 20 supervised cases. CONCLUSIONS: Overall, 78% of patients maintained positive clinical response at 6 years following POEM procedure. The recurrence rate of symptoms following POEM was 22% at a 6-year follow-up. This long-term outcome of POEM performed with trainees was comparable to those without trainees in other studies. To our knowledge, this is the longest follow-up and the largest number of patients after the POEM procedure performed with trainees.

Barriers to Lynch Syndrome Testing and Preoperative Result Availability in Early-onset Colorectal Cancer: A National Physician Survey Study.

OBJECTIVE: Although widely recommended, Lynch syndrome (LS) testing with tumor microsatellite instability (MSI) and/or immunohistochemistry (IHC) is infrequently performed in early-onset colorectal cancer (CRC), and CRC generally. Reasons are poorly understood. Hence, we conducted a national survey focusing on gastroenterologists, as they are frequently first to diagnose CRC, assessing testing barriers and which specialist is felt responsible for ordering MSI/IHC. Additionally, we assessed factors influencing timing of MSI/IHC ordering; testing on colonoscopy biopsy, opposed to post-operative surgical specimens, assists decisions on preoperative germline genetic testing and extent of colonic resection (ECR). METHODS: A 21-question web-based survey was distributed through an American College of Gastroenterology email listing. RESULTS: In total 509 completed the survey. 442 confirmed gastroenterologists were analyzed. Only 33.4% felt gastroenterologists were responsible for MSI/IHC ordering; pathologists were believed most responsible (38.6%). Cost, unfamiliarity interpreting results and unavailable genetic counseling most commonly prevented routine ordering (33.3%, 29.2%, 24.9%, respectively). In multivariable analysis, non-academic and rural settings were associated with cost and genetic counseling barriers. Only 46.1% felt MSI/IHC should always be performed on colonoscopy biopsy. Guideline familiarity predicted whether respondents felt surgical resection should be delayed until results returned given potential effect on ECR decisions. CONCLUSION: Inconsistencies in who is felt should order MSI/IHC may lead to diffusion of responsibility, preventing consistent testing, including preoperatively. Assuring institutional universal testing protocols are in place, with focus on timing of testing, can optimize care. Strategies addressing cost barriers and genomic service availability in rural and non-academic settings can enhance testing. Greater emphasis on guideline familiarity is required.
