Management of a large mucosal defect after duodenal endoscopic resection

Abstract Background The Cryoballoon focal ablation system (CbFAS) for dysplastic Barrett’s esophagus is simple, time-saving and has high therapeutic efficacy. This study aimed to evaluate the technical feasibility and tissue damage with combination therapy of endoscopic resection (ER) and CbFAS in porcine models. Methods Three pigs (A, B, and C) were included, and all ER procedures were performed by endoscopic mucosal resection using the Cap method (EMR). Combination therapy for each pig was performed as follows: (a) CbFAS was performed for a post-EMR mucosal defect for Pig A; (b) CbFAS for post-EMR scar for Pig B, and (c) EMR for post-CbFAS scar for Pig C. All pigs were euthanized at 32 days after the initial procedure, and the tissue damage was evaluated. Results All endoscopic procedures were followed as scheduled. None of the subjects experienced anorexia, rapid weight loss, bleeding, and perforation during the observation period. They were euthanized at 32 days after the initial endoscopic procedure. On histological assessment, there was little difference between the tissue that was treated with CbFAS alone and that treated with CbFAS in combination with ER. Conclusion Combination therapy with ER and CbFAS can be technically feasible, and its outcome was not significantly different from CbFAS alone in terms of tissue damage.

Esophageal Strictures

Abstract Background and study aims A disadvantage of endoscopic resection (ER) of early esophageal cancer (EC) is the high stricture rate after resection. A risk factor for stricture development is a mucosal defect after ER of ≥ 75 % of the esophageal circumference. Stricture rates up to 94 % have been reported in these patients. The aim of this study was to investigate the effectiveness of oral treatment with topical budesonide for stricture prevention after ER of early EC. Patients and methods We performed a retrospective analysis of a prospective cohort study of patients who received topical budesonide after ER of EC between March 2015 and April 2020. The primary endpoint was the esophageal stricture rate after ER. Stricture rates of our cohort were compared with stricture rates of control groups in the literature. Results In total, 42 patients were treated with ER and topical budesonide. A total of 18 of 42 patients (44.9 %) developed a stricture. The pooled stricture rate of control groups in the literature was 75.3 % (95 % CI 68.8 %-81.9 %). Control groups consisted of patients with esophageal squamous cell carcinoma with a mucosal defect after ER of ≥ 75 % of the esophageal circumference. Comparable patients of our cohort had a lower stricture rate (47.8 % vs. 75.3 %, P = 0.007). Conclusions Topical budesonide therapy after ER for EC seems to be a safe and effective method in preventing strictures. The stricture rate after budesonide treatment is lower compared to the stricture rate of patients who did not receive a preventive treatment after ER reported in the literature.

Postoperative Komplikationen

Fragestellung: Gemäss Literatur treten nach chirurgischer Behandlung entzündlich veränderter Bursae präpatellar oder am Olecranon in rund 20% der Fälle Narbenbeschwerden auf. Die Frage ist, ob durch ein endoskopisches Vorgehen, welches erstmals 1990 beschrieben wurde, die Häufigkeit dieser Komplikationen reduziert werden kann. Methode: Im Rahmen einer prospektiven Studie wurde bei 13 Patienten mit einer Bursitis ein endoskopisches Bursa-shaving durchgeführt. Alle Patienten wurden drei Wochen und sechs Monate postoperativ klinisch nachkontrolliert. Resultate: Bei neun Patienten wurde eine Bursa olecrani entfernt, viermal eine Bursa präpatellaris. In 11 Fällen handelte es sich um eine akute, infizierte Bursitis. Die Eingriffe wurden je zur Hälfte in Vollnarkose bzw. Regionalanästhesie durchgeführt. Intra- sowie postoperative Komplikationen wurden keine beobachtet. Bei den Nachkontrollen waren sämtliche Patienten beschwerdefrei und zeigten eine volle Funktion des betroffenen Gelenks. Schlussfolgerung: In unseren Händen hat sich das endoskopische Bursashaving zur chirurgischen Therapie der Bursitis bewährt. Im Vergleich zur konventionellen Bursektomie können insbesondere Wundheilungsstörungen und chronische Narbenbeschwerden reduziert werden.
