Gonorrheal infections in the oropharynx.

In the otolaryngology literature, little attention is given to pharyngeal gonococcal infections. In the past, gonorrheal stomatitis was emphasized; recent publications dealt especially with tonsillitis. A gonococcal focus in the tonsil is not easily eradicated and often leads to diseminated gonorrhea with arthritis. Homosexual contacts are of importance. Among 196 patients with suspected venereal disease (93 men and 103 women), 74 had genital or rectal gonorrhea, or both; two female patients had an isolated gonococcal pharyngeal infection. A positive gonococcal pharyngeal culture was obtained from one homosexual man who had tonsillitis. In all cases of tonsillitis in "young" adults, the otolaryngologist should be aware of the possibility of a gonorrheal infection. Even if there is the slightest suspicion, a tonsillar culture for gonococci is required, for which suction of the crypts is recommended.

Cricopharyngeal myotomy in pharyngeal paralysis. Cineradiographic and manometric indications.

A brief outline of the causes and symptoms of hypopharyngeal paresis is followed by a discussion of the diagnostic possibilities of manometry and cineradiography. It was found that the pharyngoesophageal sphincter mechanism remains intact in the case of complete paralysis of the hypopharynx. When there are severe symptoms of dysphagia, myotomy of the pharyngoesophageal sphincter is to be considered on the basis of these diagnostic findings. This procedure can lead to substantial improvement of the symptoms. Sphincterotomy yielded very favorable results in five out of nine patients, two of whom are discussed in some detail by way of illustration.

A simple endoscopic intubation technique in esophageal obstruction.

Endoscopic intubation was effected in 42 cases of malignant esophageal stenosis during the period 1979-1981. The stenosis was dilated with the aid of thermoplastic probes passed through a rigid esophagoscope of sufficient length, whereupon a tube was introduced under endoscopic control and left in situ in the malignant stricture. This "rigid" technique is suitable for process confined to the esophagus. Introduction of the tube requires adequate endoscopic skill and is not devoid of risk. Perforation, the gravest risk, occurred in two cases. Proximal tube migration was observed in five patients.

Microendoscopic surgery of the hypopharyngeal diverticulum using electrocoagulation or carbon dioxide laser.

In 1964 we started to treat hypopharyngeal (Zenker's) diverticular endoscopically, using the procedure described by Dohlman. With the increase in the number of patients (274 patients up until 1982), the technique and the instruments used have improved. This paper describes the technique we have used since 1981, which involves exposure of the tissue bridge between esophagus and diverticulum with the aid of a specially designed scope and subsequent severance of this bridge under microscopic control. In 12 cases the bridge was severed by electrocoagulation, while the CO2 laser was used for this purpose in another 12 cases. Both techniques have given good results. Essential advantages or disadvantages of either of these methods could not be elicited. We regard the use of an operating microscope as a great improvement.

Pathogenesis and endoscopic treatment of the hypopharyngeal (Zenker's) diverticulum.

The authors review the literature about the pathogenesis -still unknown- of Zenker's diverticulum as well as their experience of endoscopic treatment of this disease. From 1964 till 1988, they have treated endoscopically 507 patients, 323 by electrocoagulation, 184 by CO2-laser. The endoscopic procedure is described, consisting in precise division of the tissue bridge between the oesophagus and the diverticulum by micro-endoscopic surgery under general anesthesia. In recent years, the CO2-laser was found preferable, since it may cause less tissue necrosis and consequently less fibrous scar tissue. The results were very favourable, with more than 99% of the patients satisfied. Although many patients were old and in poor condition, only one patient died two days after operation because of cardiac failure. Complications such as bleeding, emphysema, mediastinitis and stenosis were seen in 5% of the patients, but in most cases there complications were mild and conservative therapy was sufficient. Stenosis occurred in 8 patients treated by electrocoagulation and in none of the patients treated by laser. Microendoscopic surgery is a safe and efficient method of therapy for the hypopharyngeal diverticulum.
