Perforation after rigid pharyngo-oesophagoscopy: when do symptoms and signs develop?

Hypopharyngeal perforation caused by blunt trauma during consensual fellatio: an expectant management approach

Perforation of the pharynx is a rare occurrence but has the potential to cause mediastinitis and has an attendant mortality risk. Though numerous mechanisms have been described, we report a unique case of a young woman who presented with a sore throat, odynophagia and subcutaneous emphysema, a short time after performing fellatio. A contrast swallow confirmed hypopharyngeal perforation. She was managed expectantly with nasogastric feeding and empirical antibiotics. The perforation took 4 weeks to heal, but there were no residual swallowing problems at 3-month follow-up. We will explore the incidence and causes of pharyngeal perforation and discuss the options for and risks of surgical repair. This case highlights that non-surgical management of such injuries can be both safe and feasible, and reinforces the importance of ensuring confidentiality and the need for vigilance regarding potential non-consensual injury.

[Evaluation of oesophagoscopy for staging and restaging of head and neck squamous cell carcinoma]

OBJECTIVE

Oesophagoscopy is important in diagnostic and follow up investigation in patients with head and neck squamous cell carcinoma (HNSCC). Second primary malignancies of the oesophagus have major impact on therapy of the primary tumour. Considering the low incidence of oesophageal second primaries and the serious complication of oesophageal perforation routine oesophagoscopy is being discussed.

MATERIAL AND METHODS

Incidence of oesophageal second primaries and complication rates in oesophagoscopy were identified in a systematic review. A retrospective analysis was performed in our own patient collective. To evaluate the current practice at German ENT Clinics a survey was conducted.

RESULTS

1053 oesophagoscopies in 800 patients were analysed. In 800 patients seven (0.9 %) synchronous secondary malignancies of the oesophagus occurred. In 253 follow up oesophagoscopies five (2 %) metachronous secondary malignancies were discovered. 14 (1.3 %) complications were detected; oesophageal perforation was only detected in one case (0.1 %). There was no association of certain risk factors with the incidence of secondary malignancies. The review of literature showed an incidence of secondary malignancies for Europe/USA of 1.8 % and for Asia of 4.1 %. Incidence of oesophageal perforation was 0-0.2 %. Survey results showed routine oesophagoscopy in staging (100 %) and regularly in follow up (65.3 %).

CONCLUSIONS

Oesophagoscopy is a convenient method to detect secondary malignancies of the oesophagus. To allow a selection of patients developing secondary malignancies according to risk profiles further prospective multicentre studies are required.

Current treatment and outcome of esophageal perforations in adults: systematic review and meta-analysis of 75 studies

BACKGROUND

The current prognosis of esophageal perforation and the efficacy of available treatment methods are not well defined.

METHODS

We performed a systematic review of esophageal perforations published from January 2000 to April 2012 and subjected a proportion of the retrieved data to a meta-analysis. Meta-regression was performed to determine predictors of mortality immediately after esophageal perforation.

RESULTS

Analysis of 75 studies resulted in a pooled mortality of 11.9 % [95 % confidence interval (CI) 9.7-14.3: 75 studies with 2,971 patients] with a mean hospital stay of 32.9 days (95 % CI 16.9-48.9: 28 studies with 1,233 patients). Cervical perforations had a pooled mortality of 5.9 %, thoracic perforations 10.9 %, and intraabdominal perforations 13.2 %. Mortality after esophageal perforation secondary to foreign bodies was 2.1 %, iatrogenic perforation 13.2 %, and spontaneous perforation 14.8 %. Treatment started within 24 h after the event resulted in a mortality rate of 7.4 % compared with 20.3 % in patients treated later (risk ratio 2.279, 95 % CI 1.632-3.182). Primary repair was associated with a pooled mortality of 9.5 %, esophagectomy 13.8 %, T-tube or any other tube repair 20.0 %, and stent-grafting 7.3 %.

CONCLUSIONS

Results of recent studies indicate that mortality after esophageal perforation is high despite any definitive surgical or conservative strategy. Stent-grafting is associated with somewhat lower mortality rates, but studies may be biased by patient selection and limited experience.

[Foreign bodies in ENT medicine]

A foreign body (Latin: corpus alienum) is any object originating outside the body. Of all specialties, otolaryngology covers the greatest number of natural body orifices, making foreign bodies a common diagnosis. Foreign bodies of the ear canal and nose often occur in children and are easily accessible during physical examination. Foreign bodies of the oral cavity and oropharynx are also easily removed. Esophageal and tracheobronchial foreign bodies are common in children and the elderly. A number of rigid and flexible endoscopic techniques are available for foreign body removal. In Germany, flexible endoscopy is six times more common than rigid endoscopy. Both methods are highly effective, and each has its advantages in certain situations. Rigid endoscopy is still a key in otolaryngology and can be used in case of failure of flexible techniques. It is therefore important for otolaryngologists to be proficient in both techniques.
