There was no delayed bleeding both in the SLE group and no-SLE group. Conclusion: A SLE after left-sided colorectal HM781-36B nmr ESD may contribute little to the prevention of delayed bleeding if preventive post-ESD-coagulation or clip closure is performed.

click here study aims to investigate the effects of endoscopic variceal ligation and sclerotherapy on the development and severity of PHG. Methods: Patients with esophageal varices by various etiologies presenting in the endoscopy unit of dr. Moewardi Hospital and meet the inclusion criteria between January–June 2014. The patient’s past record was reviewed retrospectively. PHG grading using Baveno scoring system. Statistical analysis using Wilcoxon Rank sum test with p < 0.05 statisticaly significant. Results: Out of 55 patients, 43 were males (78%). Ages range from 29–80 years (mean 54.62 ± 11.26 years). There were 6 patients (10.9%) with grade I esophageal varices, 7 patients (12.7%) grade

II, 39 patients (70.9%) grade III and 3 patients (5.4%) grade IV. Fourty-five patients (81.8%) had mild and 4 patients (7.3%) were suffering from severe PHG at the start. Twenty-two patients underwent sclerotherapy and 27 Endoscopic Variceal Banding Ligation (EVBL). Our finding shows relation between variceal degree with development of PHG (p = 0.003), but not with sclerotherapy (Z = −1.414, p = 0.157) and EVBL (Z = −1.134, p = 0.257) on the development and severity of PHG. Conclusion: Both sclerotherapy and EVBL do not related with the development Dynein and severity of PHG. Key Word(s): 1.

However, mucus, foam and bubbles in the upper gastrointestinal tract may remain despite using these solutions.
