Background. Radiofrequency ablation (RFA) is a palliative method known for its application in the endoscopic treatment of malignant bile duct obstruction. It may be a useful rescue method for metal stent malfunction caused by tumor ingrowth. This study aimed to examine the feasibility and safety of endoluminal RFA for occluded bilateral hilar metal stents due to tumor ingrowth in patients with malignant hilar bile duct obstruction. Methods: From March 2016 to June 2018, 11 patients with unresectable malignant hilar bile duct stricture with occluded bilateral hilar metal stents due to tumor ingrowth were enrolled. Endoluminal RFA was performed through a novel temperature-controlled catheter at a setting of 7 W power for 120 s with a target temperature of 80 °C via endoscopic retrograde cholangiopancreatography (ERCP). The patients’ demographics, clinical outcomes, and adverse events were investigated. Results: The median age was 64 (interquartile range, 54–72) years. All RFA procedures were successful. Clinical success was achieved in eight patients (72.7%). During the follow-up, eight patients (72.7%) showed stent dysfunction, and the median patency after RFA was 50 days (95% confidence interval (CI): 34–not available (NA)). All stent dysfunctions were successfully managed with ERCP. Ten patients died, and the median overall survival was 289 days (95% CI, 107–NA) from RFA to death. There was one case of mild abdominal pain after the procedure without serious adverse events. Conclusions: As a rescue therapy for occluded bilateral hilar metal stents due to tumor ingrowth, endoluminal RFA seemed to be safe and useful in selected patients.

Ligoniai, sergantys storosios žarnos vėžiu, komplikuotu obstrukcija, į gydymo įstaigas patenka skubos tvarka, neretai sunkios būklės, ir nėra idealūs kandidatai chirurginei operacijai. Šiuolaikinėje medicinos literatūroje gausėja mokslinių straipsnių apie sėkmingą ir saugų endoskopiniu būdu įkišamų savaime išsiplečiančių metalinių stentų naudojimą proktologijoje. Nors stentai ir yra brangūs, tačiau proktologinis stentavimas yra rentabili procedūra, leidžianti ligoniams, sergantiems storosios žarnos vėžiu, komplikuotu ūminė storosios žarnos obstrukcija, išvengti neatidėliotinos operacijos, o esant nerezektabiliam vėžiui, – kolostomos.

Acute colonic obstruction: endoscopical management Kęstutis Adamonis, Dainius Pavalkis, Žilvinas Saladžinskas, Algimantas Tamelis Management of malignant gastrointestinal obstruction presents a significant challenge. Most patients are in a profoundly decompensated state due to underlying malignancy and are not ideal candidates for invasive surgical procedures. In recent years, self-expandable metal stents have emerged as an effective and safe, less invasive alternative for the treatment of malignant intestinal obstruction. Although stents are expensive, the procedure appears to be cost-effective, since emergency surgery can be avoided in patients with acute bowel obstruction, and in those with advanced disease no resection of the colon is necessary. Here we report a retrospective analysis of a first self-expandable metal stent placed for colorectal obstruction at Kaunas Medical University Hospital, as well as review the literature published on self-expandable metal stent placement. Our first data confirm self-expandable metal stent efficacy in palliation of malignant intestinal obstruction. Keywords: intestinal obstruction, colorectal cancer, endoscopy, endoluminal stenting.

Radiation Esophagitis

Radiation esophagitis is a serious complication occurring in patients receiving radiotherapy for head and neck cancers. Current treatment with proton pump inhibitors and mucosal protectants provides symptomatic relief with few studies showing improvement in erosive esophagitis or ulceration. Use of self-expandable metal stents (SEMS) in cases of erosive radiation esophagitis refractory to medical therapy has not been studied. We report a case of a patient presenting with recurrent hematemesis from late (chronic) radiation esophagitis with bleeding esophageal ulceration successfully treated with SEMS placement after failure of conservative medical management, proposing a possible utility for SEMS in this setting.

Self Expandable Metal Stent

Aim: To investigate outcomes of endoscopic bilateral side-by-side placement across the papilla using 10-mm-diameter uncovered self-expandable metal stents for unresectable malignant hilar biliary obstruction. Methods: We retrospectively analyzed 23 patients who underwent endoscopic biliary uncovered self-expandable metal stent placement for unresectable malignant hilar biliary obstruction between January 2015 and September 2016 at our institution. We performed endoscopic side-by-side placement across the papilla using 10-mm-diameter longer-model uncovered self-expandable metal stents. Outcomes included the technical and functional success rates, recurrent biliary obstruction rate, time to recurrent biliary obstruction, reintervention rate, and incidence of adverse events other than recurrent biliary obstruction. Results: Of the 23 patients, 10 with malignant hilar biliary obstruction underwent endoscopic side-by-side uncovered self-expandable metal stent placement across the papilla (median age, 83 years; 6 men). The locations of malignant hilar biliary obstruction were Bismuth types II ( n = 3), III ( n = 3), and IV ( n = 4). The median common bile duct diameter was 8 mm. The technical and functional success rates were 100% and 80%, respectively. Seven patients (70%) developed recurrent biliary obstruction because of stent occlusions, including early hemobilia in two patients and late tumor ingrowth in five patients. The median time to recurrent biliary obstruction was 66 (95% confidence interval: 29–483) days. Six patients (60%) required reintervention, and 1 (10%) underwent transcatheter arterial embolization for right hepatic arterial pseudoaneurysm. Early adverse events other than recurrent biliary obstruction occurred in four patients and late adverse event in one patient. Conclusion: Endoscopic side-by-side placement across the papilla using 10-mm-diameter uncovered self-expandable metal stents was technically feasible for unresectable malignant hilar biliary obstruction; however, it might be better to avoid this method for patients with malignant hilar biliary obstruction because of high recurrent biliary obstruction rate and shorter time to recurrent biliary obstruction.

Abstract Background and study aims Endoscopic drainage of walled-off pancreatic necrosis (WOPN) is feasible when contact with the gastric or duodenal wall is present; when WOPN cannot be accessed endoscopically, a percutaneous approach can be considered. Percutaneous use of esophageal self-expandable metal stents (SEMS) to establish access to a WOPN cavity was evaluated.
