| 1 | Use of omental patch and endoscopic closure technique as an alternative to surgery after endoscopic full thickness resection of gastric intestinal stromal tumors: A series of cases显示文摘BACKGROUND Gastrointestinal stromal tumors(GISTs)originate from interstitial cells of Cajal.GISTs can occur anywhere along the gastrointestinal tract.Large lesions have traditionally been removed surgically.However,with recent innovations in advanced endoscopy,GISTs located within the stomach are now removed endoscopically.We describe a new innovative endoscopic technique to close large and hard to access defects after endoscopic full-thickness resection of gastric GISTs.CASE SUMMARY We present a series of three patients who were diagnosed with a gastric GIST.All patients underwent full-thickness endoscopic resection.In all cases,for closure of the surgical bed,conventional endoscopic techniques including hemoclips,endoloop and suturing were unsuccessful.We performed a new technique in which we pulled omental fat into the gastric lumen and completely closed the defect using endoscopic devices.All patients performed well post-procedure and computed tomography was carried out one day after the procedures which showed no extravasation of contrast.CONCLUSION The omental plug technique may be used as an alternative to surgery in selected cases of gastric perforation. | Amit H Sachdev Shahzad Iqbal Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura | 2020 | World Journal of Clinical Cases2020，8，1： | 2 |
| 2 | Acute bleeding after argon plasma coagulation for weight regain after gastric bypass: A case report显示文摘Roux-en-Y gastric bypass(RYGB)is the most commonly performed surgical procedure used to treat obesity worldwide.Despite satisfactory results in terms of weight loss,over time many patients experience weight regain.There are many factors that contribute to weight regain after RYGB,including the diameter of the gastric-jejunal anastomosis(GJA).One of the most commonly performed endoscopic procedures for weight regain after RYGB is argon plasma coagulation(APC).We report a case of hematemesis after outlet revision with APC.We highlight several treatment modalities that can be used to treat this complication.CASE SUMMARY A 45-year-old female with a history of weight regain after RYGB was referred for possible endoscopic treatment for weight regain.On endoscopic evaluation,the diameter of the GJA was 22 mm.Due to the dilated GJA,treatment with APC was performed.Several months later she reported a return of poor satiety and an increased appetite.A repeat endoscopy was then performed.The GJA was approximately 15 mm and was incompetent.APC was performed.One day post procedure she had four episodes of hematemesis.An endoscopy was performed and a large ulcer with a visible arterial vessel was visualized at the GJA.Coagulation was attempted using a Coagrasper and after initial contact with the vessel,the vessel started oozing.Due to fibrosis and the depth of ulceration in the area,clips and repeat APC could not be used.Therefore,an attempt to inject epinephrine injection was made.However,persistent oozing was noted.As a result,hemostatic powder was applied to the region of the bleeding vessel.Subsequently,no more bleeding was observed.On follow-up,the patient remained hemodynamically stable and a second look endoscopy was not performed.The patient was discharged three days later.CONCLUSION APC revision of the GJA is known to be a relatively safe and effective strategy to manage weight regain post RYGB.Anastomotic site bleeding is an infrequent and potentially life-threatening complication associated with this therapy.Endoscopic management is the first line therapy used to achieve hemostasis in these cases. | Diogo Turiani Hourneaux de Moura Amit H Sachdev Po-Wen Lu Igor Braga Ribeiro Christopher C Thompson | 2019 | World Journal of Clinical Cases2019，7，15： | 1 |
