This article discusses the clinical outcomes of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasia (SEN) in patients with cirrhosis and esophageal varices. The study found that ESD was safe and effective in achieving complete resection of SEN in these patients, with high rates of successful removal. The results suggest that ESD may be a viable treatment option for this patient population. Another study discussed in the document found that ESD was feasible and safe in cirrhotic patients with SEN near esophageal varices, with high rates of successful removal and low rates of complications. The study suggests that ESD can be a potential treatment option for cirrhotic patients with SEN, even in the presence of esophageal varices. [Extracted from the article]

Background Peroral endoscopic myotomy (POEM) is effective for the management of achalasia and its variants; however, it can be ineffective in some patients. We aimed to develop and validate a risk scoring system to predict the clinical failure of POEM preoperatively. Methods Consecutive patients who underwent POEM in 14 high volume centers between 2010 and 2020 were enrolled in this study. Clinical failure was defined as an Eckardt score of ≥ 4 or retreatment. A risk scoring system to predict the short-term clinical failure of POEM was developed using multivariable logistic regression and internally validated using bootstrapping and decision curve analysis. Results Of the 2740 study patients, 112 (4.1 %) experienced clinical failure 6 months after POEM. Risk scores were assigned for three preoperative factors as follows: preoperative Eckardt score (1 point), manometric diagnosis (−4 points for type II achalasia), and a history of prior treatments (1 point for pneumatic dilation or 12 points for surgical/endoscopic myotomy). The discriminative capacity (concordance statistics 0.68, 95 %CI 0.62–0.72) and calibration (slope 1.15, 95 %CI 0.87–1.40) were shown. Decision curve analysis demonstrated its clinical usefulness. Patients were categorized into low (0–8 points; estimated risk of clinical failure < 5 %) and high risk (9–22 points; ≥ 5 %) groups. The proportions of clinical failure for the categories were stratified according to the mid-term outcomes (log-rank test, P < 0.001). Conclusions This risk scoring system can predict the clinical failure of POEM preoperatively and provide useful information when making treatment decisions. [ABSTRACT FROM AUTHOR]

BACKGROUND : This study aimed to assess the feasibility and efficacy of the novel loop 9 method of gastrointestinal (GI) defect closure. METHODS : 20 patients underwent a GI procedure that required defect closure. Loop 9 can be delivered through a single instrument channel (3.2 mm) and released at the defect site. After it has been anchored by two clips positioned on opposite sides of the defect edge, the loop 9 is tightened by pulling the end of the suture intraluminally using biopsy forceps. Additional clips are placed to achieve complete closure. The primary outcome was complete closure rate. The secondary outcomes were closure time, sustained closure rate, and adverse events. RESULTS : Complete closure was achieved in 100 % of cases. The mean size of the mucosal defects was 17.5 mm (range 10-55 mm). The median closure time was 14 minutes. The sustained closure rate was 90 %. No adverse events were noted. CONCLUSIONS : The loop 9 technique is feasible and effective in achieving complete and sustained closure of therapeutic endoscopy-related GI defects. [ABSTRACT FROM AUTHOR]
