Prospective evaluation of an indwelling esophageal balloon dilatation feeding tube for treatment of benign esophageal strictures in dogs and cats.

ABSTRACT:

Background

Despite multiple dilatation procedures, benign esophageal strictures (BES) remain a recurring cause of morbidity and mortality in dogs and cats.

Objective

Investigate the use of an indwelling Balloon Dilatation esophagostomy tube (B-Tube) for treatment of BES in dogs and cats.

Animals

Nine dogs and 3 cats.

Methods

Animals with BES were recruited for our prospective study. Endoscopic and fluoroscopic evaluation of the esophagus and balloon dilatation were performed under general anesthesia, followed by placement of an indwelling B-Tube. The animals' owners performed twice daily at-home inflations for approximately 6 weeks. Repeat endoscopy was performed before B-Tube removal. Animals were reevaluated for changes in modified dysphagia score (MDS) after B-Tube removal.

Results

The B-Tube management was relatively well tolerated and effective in maintaining dilatation of a BES while in place. These animals underwent a median of 2 anesthetic episodes and were monitored for a median of 472 days (range, 358-1736 days). The mean MDS before treatment was 3.1 ± 0.5/4.0 and final follow-up MDS were significantly (P < .0001) improved at 0.36 ± 0.65/4.0. Eleven of 12 animals (91.7%) had improved MDS at the end of the follow-up period, with 8/12 (66.7%) having an MDS of 0/4, 2/12 (16.7%) an MDS of 1/4, and 1/12 (8.3%) an MDS of 2/4. One dog died.

Conclusions and clinical importance

The B-Tube offers an effective, and more economical method, and often decreased anesthetic time to repeated balloon dilatation procedures for the treatment of BES in dogs and cats.

Esophageal feeding tube placement and the associated complications in 248 cats.

Project description:BackgroundEsophageal feeding tubes are commonly used to provide enteral nutrition to cats, but their use is associated with adverse effects.ObjectivesTo evaluate the complications associated with e-tube placement in cats and to identify factors predisposing to these complications.AnimalsCats that had an esophageal feeding tube placed (n = 248).MethodsThis was a retrospective case review in which clinical records were interrogated across 2 referral centers to identify records of cats that had esophageal tubes placed. Clinical data were collected for signalment, clinical indication, method of placement, time of removal, and any complications. Logistic regression was then employed to assess the odds of an increase in complications, including infection and death.ResultsFor those cats that survived to discharge, tubes were in place for a median of 11 days, ranging from 1 to 93 days. Complications occurred in 35.8% of the cats, with the most common being tube dislodgement (14.5%), followed by stoma site infections (12.1%). Cats receiving glucocorticoids or oncolytic agents (OR = 3.91; 95% CI, 1.14-13.44) and with discharge at the stoma site (OR = 159.8; CI, 18.9-1351) were at an increased odds of developing a stoma site infection, whereas those with a lower weight (OR = 1.33; 95% CI, 1.02-1.75) or (pancreatic [OR = 4.33; 95% CI, 1.02-18.47], neoplastic [OR = 15.44; 95% CI, 3.67-65.07], respiratory [OR = 19.66; 95% CI, 2.81-137.48], urogenital [OR = 5.78; 95% CI, 1.15-28.99], and infectious diseases [OR = 11.57; 95% CI, 2.27-58.94]) had an increased odds of death. The duration of time in place and the cat being discharged with the tube in place were not associated with an increased risk of infection or death.Conclusions and clinical importanceOwners should be made aware of the potential risks involved and their predisposing factors.

Optimal use of biologics with endoscopic balloon dilatation for repeated intestinal strictures in Crohn's disease.

Project description:Background and aimIntestinal strictures in Crohn's disease (CD) have a high rate of repeated surgery. As alternatives to surgery, endoscopic balloon dilatation (EBD), immunomodulators (IMs), and antitumor necrosis factor alpha (anti-TNF?) have been proposed. We aimed to assess the effectiveness of the combined therapy with anti-TNF? and EBD in preventing intestinal stricture recurrence and surgery in patients with CD.MethodsThis retrospective cohort study included patients from the nationwide administrative database in Japan who were hospitalized and underwent at least one EBD between 1 April 2010 and 31 March 2017. The effectiveness of anti-TNF? was evaluated by performing survival analysis for the primary outcome. We selected the inverse probability of treatment weighting method for adjustment of covariates. As an exploratory analysis, we evaluated the association of anti-TNF? initiation timing with intestinal stricture recurrence.ResultsThe anti-TNF? exposed group had a significantly lower risk of intestinal stricture recurrence than that of the anti-TNF? nonexposed group (hazard ratio = 0.38, 95% confidence interval 0.31-0.48, P?<?0.001). Surgery-free rate was shown to have the same tendency. Anti-TNF? therapy initiation before or after EBD resulted in a lower risk of intestinal stricture recurrence than that of simultaneous treatment.ConclusionThe combined therapy with anti-TNF? and EBD could have preventive effects for intestinal stricture recurrence and surgery in hospitalized patients with CD. In particular, anti-TNF? initiation may be recommended before or after EBD, not immediately after EBD. With respect to EBD, it is important to clarify the effectiveness of combination therapy with several new medication treatments, such as biologics.

Stenting versus balloon dilatation in patients with tracheal benign stenosis: The STROBE trial.

Project description:BackgroundIt is well known that benign tracheal stenosis represents an obstacle to open surgery, and that its treatment could be challenging. Two endoscopic techniques have so far been adopted to restore tracheal patency: balloon dilatation (BA) through laryngoscopy, and tracheal stenting (ST) with rigid bronchoscopy. The main objective of this study was to compare the efficacy of BA and ST to treat benign tracheal stenosis not eligible for surgery. We also compared the rate of adverse events in the two treatment groups.MethodsA retrospective, observational cohort study was carried out at the University Hospital of Modena (Italy) from November 2012 to November 2017 in two separate departments. Patients were considered to be "stabilized" (primary outcome) if they did not report significant respiratory symptoms, or restenosis in the long-term (2 years) following the endoscopic procedure.ResultsSixty-six patients were included in the study (33 in the BA and 33 in the ST group, respectively). Unadjusted Kaplan-Meier estimates showed a greater therapeutic effect of ST compared to BA at 2 years (hazard ratio = 3.9 95%CI [1.5-9.8], p = .01). After adjusting for confounders, stratified analyses showed that this effect was significant in patients with complex stenosis, idiopathic etiology, and degree of stenosis >70%. Compared with BA, ST showed a higher rate of adverse events (p = .01).ConclusionsCompared to BA, ST seems to be more effective in achieving stabilization of tracheal patency in complex benign tracheal stenosis, although burdened with a significantly higher number of adverse effects. These findings warrant future prospective study for confirmation. Level of evidence: 3.

Is a higher frequency of esophageal dilations more effective in treating benign esophageal strictures? Retrospective, multicenter study.

Project description:Background and study aims There is still a lack of evidence-based recommendations concerning endoscopic bougienage in benign esophageal strictures. Our study aimed to assess the relevance of the time interval between endoscopic dilation (ED) sessions with regard to endoscopic and clinical response. Patients and methods We performed a retrospective study including patients treated with endoscopic bougienage for a benign esophageal stricture in two German centers. Primary endpoint was the number of ED until freedom from dysphagia was achieved. Secondary endpoints were analyses on reaching a diameter of 15 mm and on achieving clinical freedom from symptoms. Results Between April 2014 and March 2020, bougienage was used as the primary treatment for benign esophageal strictures in 238 patients (194 patients in Center 1; 44 patients in Center 2). Both centers differed in their endoscopic bougienage regime: Center 1 was characterized by a higher frequency of interventions compared to Center 2 (median: 2 days [range 1-28] vs. 10 days [range 1-41]; P <0.001). Clinical response was achieved significantly earlier using the high-frequency regimen in all patients except for those with post-radiogen strictures, who clinically benefited from a low-frequency ED program. Accordingly, patients receiving higher-frequency ED reached a significantly larger post-dilation diameter and considerably larger diameter differences. Conclusions The results of our study demonstrate that a treatment concept consisting of higher-frequency bougienages seems to be more effective in treating most types of esophageal stricture. Radiogenic strictures were the only types of stenoses that benefited from a lower frequency ED program.

Management of benign oesophageal strictures.

Project description:Benign oesophageal strictures are an important gastrointestinal condition that can cause substantial morbidity. There are many different aetiologies and each case needs careful evaluation and individualised treatment. Management usually involves targeting therapy to the underlying cause, but oesophageal dilatation is an important part of the algorithm. The recent British Society of Gastroenterology guidelines provide advice on the use of dilatation for benign strictures and cover patient preparation, the dilatation procedure and disease-specific considerations. This article provides a summary of the key messages from the guidelines and applies them to routine clinical practice. It also includes practical advice on the clinical assessment, investigation and management of benign oesophageal strictures and gives an approach to the management of refractory strictures. Areas where evidence is sparse and further research is needed are highlighted.

Endoscopic dilation of benign esophageal anastomotic strictures over 16 mm has a longer lasting effect.

Project description:BackgroundThe optimal target of endoscopic dilation of postsurgical esophageal strictures is unknown. Our aim was to compare the dilation-free period of patients who underwent dilation up to 16 mm with patients who were dilated up to 17 or 18 mm.MethodsWe retrospectively analyzed adult patients who received bougie/balloon dilation for a benign anastomotic stricture after esophagectomy. An anastomotic stricture was defined as dysphagia in combination with a luminal diameter of ≤13 mm at endoscopy. We analyzed the dilation-free period using Kaplan-Meier and multivariable Cox regression analysis.ResultsEighty-eight patients were dilated up to a maximum diameter of 16 mm and 91 patients to a diameter >16 mm. The stricture recurrence rate was 79.5 % in the 16 mm group and 68.1 % in the >16 mm group (p = 0.083). The overall dilation-free period had a median of 41.5 (range 8-3233) days and 92 (range 17-1745) days, respectively (p < 0.001). For patients who developed a stricture recurrence, the median dilation-free period was 28 (range 8-487) days and 63 (range 17-1013) days, respectively (p = 0.001). Cox regression analysis showed a reduced risk of stricture recurrence for patients who were dilated up to >16 mm: crude hazard ratio (HR) 0.57 (95 % confidence interval (CI) 0.41-0.81) and adjusted HR 0.48 (95 % CI 0.33-0.70).ConclusionsEndoscopic dilation over 16 mm resulted in a significant prolongation of the dilation-free period in comparison with dilation up to 16 mm in patients with benign anastomotic strictures after esophagectomy.

Urinary miRNAs contained in exosome of dogs and cats

Project description:The purpose of this study was the identification of RNAs contained in the urinary exosome (UExo) from dogs and cats. The quality of total RNA in isolated urinary exosome (UExo)-derived total RNAs obtained from the column-based method (urine 1 mL) was checked by using a Bioanalyzer, and samples from normal renal function (NR) group and kidney disease (KD) group were pooled as one sample for each group. We collected NR dogs (n = 37), KD dogs (n = 47), NR cats (n=43), and KD cats (n = 45). For the next generation sequencing, libraries were prepared according to the manufacturer’s protocols and sequenced using 50-base reads acquired by using a HiSeq 2000 platform. The December 2011 (GRCm38/mm10) mouse (Mus musculus) genome data were used as reference. As a result, we could identify the miRNA from these samples.
