Abstract Objective: Bronchopleural fistula is a rare but life-threatening event with limited therapeutic options. Aim of our study is to investigate the efficacy and safety of the modified silicone stent in patients with bronchopleural fistula.Method: Between March 2016 and April 2020, we retrospectively collected 17 patients with bronchopleural fistula and who underwent bronchoscopic placement of the modified silicone sten. The Y-shaped stent was tailored and sutured manually. The initial success, clinical success, the cured rate and complications were recorded. Results: Placement of the modified silicone stent was successful in 16 patients on first attempt (initial success rate was 94.1%). The median follow-up time was 107(rang, 5-431) days. The amelioration of respiratory symptoms was reported in all patients. There were 14 patients with empyema, the daily drainage was significantly decreased in 11 patients over time, and the purulent fluid completely disappeared in six patients. The clinical success rate was 76.5%. There were seven stents was removed during follow-up, four (26.7%) removed for cured fistula, two for the severe proliferation of granulation tissue and one for the dislocation of stent. No severe adverse events of stent migration and suture dehiscence happened. There were three cases were lost to follow-up and seven patients succumbed. The cause of death included progression of primary malignance, the uncontrolled infection, myocardial infarction and left heart failure.Conclusion: The modified silicone stent may be an effective and safe option for bronchopleural fistula patients in whom the conventional therapy is inappropriate and contraindicated.

Abstract Background and study aims Endoscopic treatment of Zenker’s Diverticulum (ZD) using a flexible endoscope and a diverticuloscope consists of myotomy of the cricopharyngeus muscle, sparing the lower part of the diverticular septum. However, recurrence occurs in up to 54 % of patients at 4 years. We assessed the feasibility and safety of a complete septotomy in endoscopic treatment of ZD. Patients and methods We conducted a retrospective analysis of a prospectively collected database at a single referral center. All consecutive patients treated by complete resection of the diverticular wall were included. The endoscopic technique used a distal attachment cap and division of the ZD septum using a Dual Knife or a Triangle Tip knife in endocut mode, until the esophageal muscularis propria was seen and no residual diverticulum remained. Symptoms were evaluated using the Augsburger questionnaire. Results Nineteen patients, 10 of whom were men with mean age 79 ± 12 years, were treated by complete septotomy for a symptomatic ZD with a median size of 2.5 cm (range 1–5 cm). The clinical success rate was 100 % and the complication rate was 10 % (one pneumonia and one atrial fibrillation). Median hospital stay was 2 days (range 1–3 days). On Day 1 esophagogram, no extraesophageal contrast leakage was seen, periesophageal CO2 was still visible in two patients, and complete ZD regression was seen in 63 % of patients. The 6-month clinical success rate was 100 %, with two patients lost to follow-up, and a median symptom score of 0 (range 0–4). After a mean ± SD follow-up of 9 ± 5 months, the clinical success rate was 94 % (16/17). Conclusion Complete endoscopic septotomy is a feasible and safe therapeutic modality in patients with symptomatic ZD that does not require use of a diverticuloscope, and with good short-term efficacy. The complete regression of the diverticulum observed on Day 1 in 63 % of patients could be a marker of long-term clinical success.

Introduction: Hemodialysis patients with an arteriovenous fistula can use buttonhole techniques for cannulation. Although buttonholes generally work well, patients may report difficult and painful cannulation, and buttonholes may fail over time. We aimed to assess the effectiveness of tract dilation in treatment of failing buttonholes. Methods: We retrospectively analyzed data from patients treated with buttonhole tract dilation at an outpatient vascular access center between January 2013 and August 2015. Results: Data from 23 patients were analyzed. There were 51 tract dilation procedures during 36 encounters for failing arteriovenous fistula buttonhole tract(s). The technical success rate for established tract dilation with “blunt-recanalization” was 90% (n = 46). The five remaining buttonholes had “sharp-recanalization” to create and dilate new tract through the buttonhole. For 46 buttonholes treated with “blunt-recanalization,” there was an 85% clinical success rate at one week (39 buttonholes), and one was lost to follow-up; there was a 70% clinical success rate after one month (32 buttonholes). In the five buttonholes with “sharp-recanalization,” there was only one clinical success with p < 0.05 for difference in success rate compared to “blunt-recanalization” at both one week and one month. There was one complication from “sharp-recanalization” requiring abandonment of the buttonhole tract. Discussion: Buttonhole tract dilation is a useful method to treat difficult cannulation and painful cannulation and has the potential to extend the life of failing buttonholes.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Background. Endoscopic transpapillary gallbladder stenting (ETGBS) is an effective procedure for treating high-risk patients with acute cholecystitis and severe comorbidities. However, the efficacy of ETGBS for recurrent cholecystitis (RC) remains unclear. This study aimed to explore its efficacy in patients with RC for whom cholecystectomy is contraindicated because of its high surgical risk.Methods. Data on 19 high-risk patients who had undergone ETGBS for RC after initial conservative therapy in our institution between June 2006 and May 2012 were retrospectively examined. The primary outcome was the clinical success rate, which was defined as no recurrences of acute cholecystitis after ETGBS until death or the end of the follow-up period. Secondary outcomes were technical success rate and adverse events (AEs).Results. The clinical success rate of ETGBS was 100%, the technical success rate 94.7%, and AE rate 5%: one patient developed procedure-related mild acute pancreatitis. The clinical courses of all patients were as follows: four died of nonbiliary disease, and the remaining 15 were subsequently treated conservatively. The median duration of follow-up was 14.95 months (range 3–42 months).Conclusions. ETGBS is an effective alternative for managing RC in high-risk patients with severe comorbidities.

Abstract Background: Data on the long-term outcomes of gastric peroral endoscopic myotomy (G-POEM) for refractory gastroparesis are lacking. We report the results of a large multicenter long-term follow-up study of G-POEM for refractory gastroparesis. Methods: This was a retrospective multicenter study of all G-POEM operations performed in seven expert French centers for refractory gastroparesis with at least 1 year of follow-up. The primary endpoint was the 1-year clinical success rate, defined as at least a 1-point improvement in the Gastroparesis Cardinal Symptom Index (GCSI). Results: 76 patients were included (60.5 % women; age 56 years). The median symptom duration was 48 months. The median gastric retention at 4 hours (H4) before G-POEM was 45 % (interquartile range [IQR] 29 % – 67 %). The median GCSI before G-POEM was 3.6 (IQR 2.8 – 4.0). Clinical success was achieved in 65.8 % of the patients at 1 year, with a median rate of reduction in the GCSI score of 41 %. In logistic regression analysis, only a high preoperative GCSI satiety subscale score was predictive of clinical success (odds ratio [OR] 3.41, 95 % confidence interval [CI] 1.01 – 11.54; P = 0.048), while a high rate of gastric retention at H4 was significantly associated with clinical failure (OR 0.97, 95 %CI 0.95 – 1.00; P = 0.03). Conclusions: The results confirm the efficacy of G-POEM for the treatment of refractory gastroparesis, as evidenced by a 65.8 % clinical success rate at 1 year. Although G-POEM is promising, prospective sham-controlled trials are urgently needed to confirm its efficacy and identify the patient populations who will benefit most from this procedure.

Introduction. Colorectal anastomotic leak or stricture is a dreaded complication leading to significant morbidity and mortality. The novel use of self-expandable metal stents (SEMS) in the management of postoperative colorectal anastomotic leaks or strictures can avoid surgical reintervention. Methods. Retrospective study with particular attention to the indications, operative or postoperative complications, and clinical outcomes of SEMS placement for patients with either a colorectal anastomotic stricture or leak. Results. Eight patients had SEMS (WallFlex stent) for the management of postoperative colorectal anastomotic leak or stricture. Five had a colorectal anastomotic stricture and 3 had a colorectal anastomotic leak. Complete resolution of the anastomotic stricture or leak was achieved in all patients. Three had recurrence of the anastomotic stricture on 3-month flexible sigmoidoscopy follow-up after the initial stent was removed. Two of these patients had a stricture that was technically too difficult to place another stent. Stent migration was noted in 2 patients, one at day 3 and the other at day 14 after stent placement that required a larger 23 mm stent to be placed. Conclusions. The use of SEMS in the management of colorectal anastomotic leaks or strictures is feasible and is associated with high technical and clinical success rate.
