Outcomes of Self-Esophageal Dilation for Head and Neck Cancer Patients

Improved functional oral intake and exercise training attenuate decline in aerobic capacity following chemoradiotherapy in patients with esophageal cancer

PURPOSE

To investigate the impact of chemoradiotherapy on the physical fitness of patients with oesophageal cancer, and the clinical factors influencing it.

METHOD

A total of 67 participants successfully completed the study, with 18 of them engaging in supervised, in-hospital aerobic training at moderate intensity for a minimum of 20 sessions. Cardiopulmonary exercise testing, hand grip strength, body composition assessed via bioelectrical impedance analysis, patient-generated subjective global assessment, albumin, and the Functional Oral Intake Scale (FOIS) were evaluated before chemoradiotherapy and 6-8 weeks after its completion.

RESULT

Among the participants, cardiopulmonary fitness, hand grip strength, and phase angle of BC-BIA declined during chemoradiotherapy. Before and after chemoradiotherapy, V̇O2peak was 19.6 ± 4.4 and 17.4 ± 3.9 mL/min/kg respectively. The improvement in FOIS during chemoradiotherapy showed a positive correlation with changes in aerobic capacity. Additionally, exercise training was associated with attenuating the decline in aerobic capacity.

CONCLUSION

Physical fitness deteriorated in patients with oesophageal cancer following chemoradiotherapy. Improvement in dysphagia helps maintain aerobic capacity. Additionally, exercise training has the potential to mitigate the decline. This discovery can serve as a reference for enhancing holistic care for patients with oesophageal cancer.

Swallowing after total laryngectomy surgery: where are we after 150 years?

Purpose of review

Recent findings

Dysphagia is a common sequela following total laryngectomy surgery; however, there is significant variability in its assessment and management. Manometry enables an accurate understanding of the underlying mechanism of dysphagia and precise assessment of any oesophageal dysfunction. EndoFLIP is a useful tool to better understand dysfunction of the upper oesophageal sphincter particularly to detect stricture.

Summary

Following total laryngectomy surgery, dysphagia is common; clinicians need to be alert to early indicators of dysfunction and understand the tools to comprehensively characterize swallow function. Accurate diagnosis of a stricture is important, as this aspect of dysfunction can be modified, and may alleviate surrogate problems such as a leaking voice prosthesis. Clinicians should have a low threshold to examine patients for oesophageal dysfunction due to the high prevalence of dysmotility following a laryngectomy.

Self-dilatation of benign oesophageal strictures: a literature review

BACKGROUND

Benign oesophageal strictures can have several aetiologies and often require serial endoscopic dilatation. The aim of this study was to review the existing literature regarding the efficacy of self-dilatation for benign oesophageal strictures.

METHODS

This study presents the results of a systematic review that was performed on the available literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Full-text articles from Medline, PubMed and Embase were used, as well as associated reference lists. This study systematically reviews the literature to present the efficacy and different outcome measurements associated with self-dilatation of benign oesophageal strictures.

RESULTS

This study identified 13 articles with 274 participants.

CONCLUSION

Self-dilatation for refractory benign oesophageal strictures is effective regardless of aetiology. It is well tolerated, safe and leads to lasting symptom resolution in the majority of patients.

Feasibility and Safety of Office-Based Transnasal Balloon Dilation for Neopharyngeal and Proximal Esophageal Strictures in Patients with a History of Head and Neck Carcinoma

The aim of this study was to assess feasibility and safety of office-based transnasal balloon dilation of neopharyngeal and proximal esophageal strictures in patients with a history of head and neck carcinoma. The secondary objective was to explore its effectiveness. This prospective case series included patients previously treated for head and neck carcinoma with neopharyngeal or proximal esophageal strictures who underwent transnasal balloon dilation under topical anesthesia. The target dilation diameter was 15 mm; if necessary dilation procedures were repeated every 2–4 weeks until this target was reached. Completion rates, adverse events, and patient experiences measured by VAS scores (0 = no complaints – 10 = unbearable complaints), dysphagia scores based on food consistency (0 = no dysphagia – 5 = unable to swallow liquids/saliva), and self-reported changes in swallowing symptoms were recorded. Follow-up was 2 months. Twenty-six procedures were performed in 12 patients, with a completion rate of 92%. One minor complication occurred, i.e. an infection of the dilation site. Tolerance of the procedure was good (median VAS = 2). The dysphagia score improved after a mean of 2.2 procedures per patient, however not significantly. Eight patients reported improvement in dysphagia, of whom 3 had recurrence of dysphagia within 1 month post-treatment. Office-based transnasal balloon dilation is a feasible and safe in-office procedure which is well-tolerated by patients. The dilations can improve dysphagia, although effects might be transient.

Outcomes of Combined Antegrade-Retrograde Dilations for Radiation-Induced Esophageal Strictures in Head and Neck Cancer Patients

The purpose of this study is to analyze outcomes of combined antegrade-retrograde dilations (CARD). This retrospective study was conducted on 14 patients with a history of head and neck cancer, treated with radiation therapy that was complicated by either complete or near-complete esophageal stenosis. All patients had minimal oral intake and depended on a gastrostomy tube for nutrition. Swallow function before and after CARD was assessed using the Functional Oral Intake Scale, originally developed for stroke patients and applied to head and neck cancer patients. Patients undergoing CARD demonstrated a quantifiable improvement in swallow function (p = 0.007) that persisted at last known follow-up (p = 0.015) but only a minority (23.1%) achieved oral intake sufficient to obviate the need for tube feeds. Complication rates were 24% per procedure or 36% per patient, almost all complications required procedural intervention, and all complications occurred in patients with complete stenosis. Our study suggests further caution when considering CARD, careful patient selection, and close post-operative monitoring.

National Database Outcomes of Esophageal Dilations

OBJECTIVES/HYPOTHESIS

To better assess rates of postoperative complications and mortality following esophageal dilation, and to identify factors associated with adverse outcomes.

STUDY DESIGN

Observational, retrospective cohort study.

METHODS

We queried a national database of insurance claims for Current Procedural Terminology (CPT) codes representing esophageal dilation performed between 2011 and 2017. Patients aged 18 to 100 who were continuously enrolled with their insurance provider were included. Demographic information, additional CPT codes, concomitant diagnoses, and anticoagulant medication data were collected for all patients included. Postoperative mortality was assessed and International Classification of Diseases (ICD)9/10 codes for complications, including esophageal perforation, hemorrhage, mediastinitis, and sepsis were flagged.

RESULTS

We identified 202,965 encounters for esophageal dilation. Of these procedures, 193 were performed on a patient who underwent percutaneous endoscopic gastrostomy (PEG) during the study period and was analyzed separately. Another 244 dilations were excluded due to repeat entries. Of the remaining 202,528 procedures remaining, 42,310 were repeat dilations in the same patient. Data analysis was confined to each patient's initial dilation. 160,218 initial dilations remained. Of these, 62,107 were performed on male patients and 98,111 were performed on female patients. The average age was 57.7 years. There were 12 mortalities within 30 days postoperatively, representing 0.0075% of all dilations. Esophageal perforation and esophageal hemorrhage were the most common reported complications, with 139 and 110 occurrences, respectively. The overall per-dilation complication rate was 0.215%.

CONCLUSIONS

Evidence from a national insurance claim database suggests that esophageal dilation is a safe procedure with a low rate of serious complications and a 30-day all-cause mortality rate of less than 1 per 10,000 dilations.
