RISK OF DE NOVO BARRETT'S ESOPHAGUS POST SLEEVE GASTRECTOMY: A SYSTEMATIC REVIEW AND META-ANALYSIS OF STUDIES WITH LONG TERM FOLLOW UP.

BACKGROUND: Sleeve gastrectomy (SG) is one of the most commonly performed bariatric procedures worldwide. Gastroesophageal reflux disease (GERD) is a major concern in patients undergoing SG and is a risk factor for Barrett's esophagus (BE). We conducted a systematic review and meta-analysis to assess the incidence of and analyze predictive factors for post-SG BE. METHODS: A comprehensive literature search was conducted in April 2024, for studies reporting on incidence of BE, erosive esophagitis (EE) and hiatal hernia (HH) post SG. Primary outcomes were post SG pooled rates of de novo BE, EE, GERD symptoms, proton pump inhibitor (PPI) use and HH. Meta-regression analysis was performed to assess if patient and post SG factors influenced the rates of post SG BE. RESULTS: Nineteen studies with 2046 patients (79% females) were included. Mean age was 42.2 years (SD 11.1) and follow up ranged from 2 to 11.4 years. The pooled rate of de novo BE post SG was 5.6% (CI 3.5-8.8). Significantly higher pooled rates of EE [Risk Ratio (RR) 3.37], HH [RR 2.09], GER/GERD symptoms [RR 3.32] and PPI use [RR 3.65], were found among patients post SG. GER/GERD symptoms post SG positively influenced the pooled BE rates, while age, sex, BMI, post SG EE and HH did not. CONCLUSION: Our analysis shows that SG results in a significantly increased risk of de novo BE and higher rates of EE, PPI use and HH. Our findings suggest that clinicians should routinely screen patients with SG for BE and future surveillance intervals should be followed as per societal guidelines.

Endoscopic cryotherapy: Indications, techniques, and outcomes involving the gastrointestinal tract.

Endoscopic cryotherapy is a technique utilized for the ablation of target tissue within the gastrointestinal tract. A cryotherapy system utilizes the endoscopic application of cryogen such as liquid nitrogen, carbon dioxide or liquid nitrous oxide. This leads to disruption of cell membranes, apoptosis, and thrombosis of local blood vessels within the target tissue. Several trials utilizing cryotherapy for Barrett's esophagus (BE) with variable dysplasia, gastric antral vascular ectasia (GAVE), esophageal carcinoma, radiation proctitis, and metastatic esophageal carcinomas have shown safety and efficacy. More recently, liquid nitrogen cryotherapy (cryodilation) was shown to be safe and effective for the treatment of a benign esophageal stricture which was refractory to dilations, steroid injections, and stenting. Moreover, liquid nitrogen cryotherapy is associated with less post procedure pain as compared to radiofrequency ablation in BE with comparable ablation rates. In patients with GAVE, cryotherapy was found to be less tedious as compared to argon plasma coagulation. Adverse events from cryotherapy most commonly include chest pain, esophageal strictures, and bleeding. Gastric perforations did occur as well, but less often. In summary, endoscopic cryotherapy is a promising and growing field, which was first demonstrated in BE, but the use now spans for several other disease processes. Larger randomized controlled trials are needed before its role can be established for these different diseases.

Endo-sponge in management of anastomotic colorectal leaks: a systematic review and meta-analysis.

Background and study aims Following colorectal surgery, anastomotic dehiscence and leak formation has an incidence of 2 % to 7 %. Endo-SPONGE has been applied in the management of anastomatic leaks (ALs) after colorectal surgery. This is the first systematic review and meta analysis to evaluate the efficacy and safety of Endo-SPONGE in the management of colorectal ALs. Patients and methods The primary outcomes assessed were the technical and clinical success of Endo-SPONGE placement in colorectal ALs. The secondary outcomes assessed were the overall adverse events (AEs) and the AE subtypes. Pooled estimates were calculated using random-effects models with 95 % confidence interval (C. I.). The statistical analysis was done using STATA v16.1 software (StataCorp, LLC College Station, Texas, United States). Results The analysis included 17 independent cohort studies with a total of 384 patients. The rate of technical success was 99.86 % (95 % CI: 99.2 %, 100 %; P  = 0.00; I 2  = 70.69 %) and the calculated pooled rate of clinical success was 84.99 % (95 % CI: 77.4 %, 91.41 %; P  = 0.00; I 2  = 68.02 %). The calculated pooled rate of adverse events was 7.6 % (95 % CI: 3.99 %, 12.21 %; P  = 0.03; I 2  = 42.5 %) with recurrent abscess formation and bleeding being the most common AEs. Moderate to substantial heterogeneity was noted in our meta-analysis. Conclusions Endoscopic vacuum therapy appears to be a minimally invasive, safe, and effective treatment modality for patients with a significant colorectal leak without any generalized peritonitis with high clinical and technical success rates and a low rate of adverse events. Further prospective or randomized controlled trials are needed to validate our findings.

Characterization of fall patients: Does age matter?

INTRODUCTION: Evaluating age-specific fall characteristics is important for prevention programs. The aim was to characterize fallers who presented to our trauma center. We hypothesized that fall characteristics and outcomes would vary with age. METHODS: Data were retrospectively collected from the trauma registry and electronic medical records during January 1st, 2014-December 31st, 2015. Data were analyzed by Chi-square test with Yates' continuity correction and one-way ANOVA with Bonferroni's multiple comparisons test. RESULTS: There were 1541 fallers, 814 (52.8%) were male. Ages ranged from 11 months to 100years. The admission rate was high at 86%, with an average hospital stay of 5.7days. Patients in the 0-18 and 19-45age groups spent significantly less time in the hospital (p<0.0001). Elderly patients had the highest average injury severity score (p<0.0001). However, the youngest patients required surgery more often (p=0.0004). The overall mortality rate was 3.6% and 52.8% were male. The mortality rate increased with age, from 0% for the 0-18 age group to 6.9% for patients ≥65years of age. Remarkably, fallers in the 19-45 and 46-64age groups predominantly died from ground level falls even though the average fall height in these groups was the highest (p<0.0001). More fallers in the 19-45 and 46-64age groups tested positive for alcohol/drug use (p<0.0001). Middle-aged and elderly patients were more likely to be discharged to a skilled nursing or rehabilitation facility compared to younger patients who were discharged home. CONCLUSIONS AND PRACTICAL APPLICATIONS: Fall characteristics and outcomes varied with age. Data on age-specific characteristics, outcomes, and risk factors of falls will help in developing targeted interventions and may lead to better approaches to treat patients.
