Thyroid Cancer Presenting as Aspiration Pneumonia: A Tale of Retrosternal Goiters

Abnormal enlargement of the thyroid gland is called goiter. Structurally, it can be nodular or diffuse. Usually, it presents as an anterior cervical mass; however, less commonly, it presents as a retrosternal mass causing symptoms of compression on the surrounding structures. Most patients with goiter are asymptomatic due to the euthyroid nature of the disease. However, sometimes they can be hypo or hyperthyroid depending on the etiology of the goiter. Here, we present the case of a patient without any previously known goiter who presented to the hospital with shortness of breath and was found to have hypoxic respiratory failure as his first noticed sign of thyroid disease. Diagnostic workup revealed retrosternal goiter causing compression effect on the esophagus and trachea resulting in dysphagia and aspiration. The patient was treated with feeding tube placement, followed by surgical resection of the mediastinal mass.

Assessing the Clinical Utility of the Early Postoperative Pharyngogram in Hypopharyngeal Surgery for Dysphagia

OBJECTIVES/HYPOTHESIS

To evaluate the clinical utility of postoperative contrast x-ray pharyngograms (XRP) for detecting pharyngoesophageal leaks following hypopharyngeal dysphagia surgery.

STUDY DESIGN

Retrospective cohort study.

METHODS

Medical records were reviewed of patients undergoing endoscopic (E-) or open (O-) Zenker's diverticulectomy (-ZD) with cricopharyngeal myotomy (-CPM) and CPM alone from 2008 to 2020 at one academic institution. Exclusion criteria were patients who were fed enterally or underwent repair of epiphrenic diverticula or O-CPM during laryngectomy. XRP clinical indication, impact on clinical care, and factors associated with use patterns were examined using descriptive statistics and logistic regression (LR).

RESULTS

Of 152 subjects, 52% underwent O-ZD, 30% O-CPM, 15% E-ZD, and 3% E-CPM. An XRP was ordered for 65% of subjects, mostly routinely (94%). Among the four clinically apparent leaks observed in this cohort, early postoperative XRP confirmed one. It did not identify any clinically silent leaks. In univariate LR, undergoing XRP was associated with increasing day of diet advancement (odds ratio [OR] 4.7, 95% confidence interval [CI] 2.5-10.5) and hospital stay duration (OR 3.2, 95% CI 2.1-5.2), as well as surgeon specialty of otolaryngology compared to general surgery (OR 12.8, 95% CI 4.8-40.8) and procedure sub-type (O-CPM: OR 0.03, 95% CI 0.002-0.16). In multivariate LR, the following variables were significantly associated with XRP use: hospital stay (OR 1.7; 95% CI 1.1-3.0), otolaryngology (OR 105; 95% CI 15.4-2193), O-CPM (OR 0.03; 95% CI 0.002-0.16), and E-CPM (OR 0.04, 95% CI 0.002-0.60).

CONCLUSIONS

Prospective, multi-institutional studies are needed to confirm the low clinical utility we observed of early, postoperative XRP following hypopharyngeal surgery for dysphagia.

Transoral Laser-Assisted Diverticulectomy: Swallow Study Results after Complete Endoscopic Pouch Excision for Zenker's Diverticulum

OBJECTIVE

Transoral endoscopic laser-assisted diverticulotomy (TELD) with diverticulectomy and diverticuloplasty (TELD + DD) for the management of Zenker's diverticulum (ZD) has been utilized by our institution since 2016 in attempts to reduce residual pouch size. This technique involves complete endoscopic pouch excision with partial advancement of mucosal flaps. Our study compares the subjective outcomes, objective outcomes, and complication rates between TELD and TELD + DD.

METHODS

A retrospective cohort study was performed on patients who underwent TELD or TELD + DD by a single surgeon at a tertiary academic center (2013-2019). Videofluoroscopic swallow studies (VFSS) with esophagram, Eating Assessment Tool (EAT-10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and 3 month follow-up visits. A single blinded reviewer recorded height, width, and depth of pre and postoperative pouches with volumetric analysis performed assuming an ellipsoid shape. Comorbidities, complications, postoperative course, and recurrence were recorded.

RESULTS

Of the 75 patients that met criteria, 27 underwent TELD + DD and 48 underwent TELD. Eighteen TELD + DD and 37 TELD had both pre and post-operative VFSS. TELD + DD and TELD had a 96 ± 7% and 87 ± 16% reduction in pouch volume, respectively (t-test; P = .01). Complications (TELD + DD 7%, TELD 17%, fisher's exact; P = .31) and final subjective outcomes after adjusting for initial were not significantly different between methods (EAT-10 with TELD + DD ∆ + 1.3, P = .18; RSI ∆ + 1.4, P = .29; FOSS ∆-0.02, P = .91). One short-term recurrence was reported with TELD.

CONCLUSION

Use of TELD + DD is associated with a statistically significantly decreased residual pouch size with no significant difference in short-term subjective outcomes. Complication rates and short-term recurrence rates are comparable. Long-term recurrence rates will require further studies to characterize.

Cricopharyngeal Myotomy in Inclusion Body Myositis: Comparison of Endoscopic and Transcervical Approaches

OBJECTIVE

Inclusion body myositis (IBM) is a progressive inflammatory myopathy with dysphagia as a debilitating sequalae. Otolaryngologists are consulted for surgical candidacy when there are findings of cricopharyngeal dysfunction. We aim to compare transcervical cricopharyngeal myotomy (TCPM) versus endoscopic cricopharyngeal myotomy (ECPM) in the IBM population with particular focus on objective swallow study outcomes, complications, and recurrence rates.

METHODS

A retrospective cohort study was performed on IBM patients who underwent TCPM or ECPM (1981-2020) in the Department of Otolaryngology at a tertiary academic center with a high volume IBM referral base. Videofluoroscopic swallow studies, Eating Assessment Tool (EAT-10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and follow-up visits. Baseline patient characteristics, intraoperative data, and postoperative course were recorded.

RESULTS

Forty-one patients were identified (18 TCPM; 23 ECPM). There was no significant difference in the recurrence rates, complications, hospitalization length, operative time, or return to preoperative diet between approaches. For the 12 patients (11 ECPM; 1 TCPM) that had subjective swallow data, there was a statistically significant difference in the pre and postoperative scores for EAT-10, RSI, and FOSS (P < .05). There was a statistically significant improvement in the degree of narrowing between pre and postoperative imaging for both approaches (P < .05).

CONCLUSION

Both TCPM and ECPM are safe approaches for the management of dysphagia in patients with IBM with objective evidence of cricopharyngeal dysfunction. Cricopharyngeal myotomy is a durable technique that has demonstrated improved subjective and objective outcomes in this patient population.
