Objective: To evaluate the early results of endoscopic treatment of vesicoureteral reflux (VUR) in children using polyacrylate polyalcohol copolymer (PPC).
Patients And Methods: We retrospectively reviewed 45 patients treated with subureteric injection of PPC in our clinic. The results of voiding cystouretrography performed on the 3rd postoperative month and the results of 1-year follow-up were evaluated.
Results: A total of 45 patients (57 ureters) underwent injection of PPC. The mean age of the patients was 6.5 years. There were 6 (10.5%) grade 1, 7 (12.2%) grade 2, 26 (45.6%) grade 3, 16 (28%) grade 4, and 2 (3.5%) grade 5 VUR. There were 11 overactive bladders, 2 duplex collecting systems, and 4 posterior urethral valves among the patients. Voiding cystouretrography postoperatively at the 3rd month showed that VUR had disappeared in 82.5% (47/57) of the ureters, downgraded to grade 2 and 3 in 7% (4/57), persisted in 5.2% (3/57) and upgraded in 5.2% (3/57). The success rate at the end of the first year was 98.1%. The procedure was free of complications such as fever, dysuria, lumbar pain or obstruction in all patients. No patient showed VUR recurrence at the end of the first year.
Conclusions: The short-term results of our patients suggested that PPC can be safely and successfully used in the endoscopic treatment of VUR in children. However, further prospective, controlled trials showing the long-term results of the patients are needed.

Background: Gastrointestinal subepithelial lesions (SELs) range from benign to malignant. Endoscopic ultrasound (EUS)-guided fine-needle biopsy (EUS-FNB) is used widely for pathological diagnosis of SELs. Early diagnosis and treatment are important because all Gastrointestinal stromal tumors (GISTs) have some degree of malignant potential.

Background: Endoscopic submucosal dissection is increasingly used to treat early-stage colorectal cancer. This study evaluated the feasibility of endoscopic submucosal dissection in this setting and the determinants of lymph node metastasis.
Methods: We reviewed patients who underwent colorectal endoscopic submucosal dissection for early-stage colorectal cancer at a tertiary center between 2011 and 2023.

Background And Aims: We sought to ascertain how prior exposure to TNF antagonists impacts treatment response with various classes of advanced therapies in patients with ulcerative colitis (UC), through a systematic review and meta-analysis.
Methods: Through a systematic review of multiple databases through June 30, 2024, we identified 17 RCTs in 8871 adults with moderate-severe UC who were treated with different advanced therapies vs. placebo, and reported efficacy in induction of clinical remission, stratified by prior exposure to TNF antagonists.

Background And Aims: Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. The published data on the accuracy of the detection of pancreas divisum by linear-array endoscopic ultrasound (L-EUS) is limited. The current study aimed to assess the diagnostic accuracy of L-EUS compared with magnetic resonance cholangiopancreatography (MRCP) for identifying PD.
