JOURNAL FREE ACCESS133Xe ventilation and 9mTc-MAA perfusion were studied on 4 children with radiolucent endobronchial foreign bodies. Scintigraphic findings showed ventilation defects, washout delays and perfusion defects on the obstructive regions due to foreign bodies which had been confirmed by the bronchoscopy. Ventilation scintigraphy had more diagnostic value because ventilation defects were greater than those of perfusion. Furthermore, according to the observation of both ventilation distribution and washout phase, we could estimate endobronchial changes due to foreign bodies in more detail.
The authors emphasize that 133Xe ventilation study which is harmless should be more applicated for the detection of radiolucent endobronchial foreign bodies of children.View full abstractDownload PDF (9263K) -

JOURNAL FREE ACCESSIt is very difficult to observe the postcricoid area of the hypopharynx and the upper end of the esophagus with a fiberscope because their lumens are usually closed. When the gastrointestinal fiberscope (GIF type P2, Olympus Co. Ltd.) and nasopharyngo-laryngofiberscope (ENF type LB, Olympus Co. Ltd.) were used in a case of hypopharyngeal (postcricoid) cancer for comparison, the ENF-LB is too slender to keep a favorable position for observation and insufficient to extend the postcricoid lumen. Therefore, it is not suitable for observation on these regions as compared with the GIF-P2. A small erosion in the postcricoid area of the hypopharynx after passage of fish bones could be diagnosed by mounting the hood on the GIF-P3. When the ENF-LB was simultaneously inserted through the nose while the gastrointestinal fiberscope (GIF type XQ10, Olympus Co. Ltd.) was being orally inserted, the pyriform sinus could be favorably observed because the hypopharynx cavity had been extended by the GIF.
From the above-mentioned experiences, the balloon (Top Co. Ltd.) which had been used in the sclerotherapy of the esophageal varix was mounted on the end of the GIF-XQ10 in order to obtain an enough visual field by extending the lumen of the hypopharynx and the upper end of the esophagus. It was used successfully in diagnosing and treating the ectopic gastric mucosa and foreign body in the esophagus.View full abstractDownload PDF (5881K) -

JOURNAL FREE ACCESSA case of adhesive stenosis of the hypopharynx following the lateral pharyngotomy and the CO2 laser surgery for the benign tumor of the larynx was reported and the treatment was discussed. The patient complained of severe dysphagia 2 weeks after the latest surgical treatment with CO2 laser.
On fiberscopic examination, the left arytenoid eminence and the right ary-epiglottic fold adherent to the posterior wall of the hypopharynx were observed. Because of the long and strong adhesion, surgical treatment was thought to be superior to the dilation bouginage.
After removing the scar tissue operatively, two-stage reconstruction of the hypopharynx was performed with horizontal neck flap successfully.View full abstractDownload PDF (4268K) -
Combination Therapy with Laser Surgery and InterferonRyusuke Saito, Setsuo Ueda, Reiko Date, Kinya Uno, Mario Quijano, Yosh ...1985 Volume 36 Issue 1 Pages 19-25

JOURNAL FREE ACCESSThree patients with aggressive juvenile laryngeal papillomatosis were treated with the combined use of endoscopic laser surgery and systemic administration of alpha-type interferon (Human Lymphoblastoid Interferon). All the three cases had the onset of the disease under four years of age and were of fulminant type with strong tendency of recurrence. The current results were, however, complete disappearance of papilloma in two cases and a tracelike remnant in one case and the control of papilloma was successful.
Since there is no single method of treatment to eradicate laryngeal papilloma in children consistently, it seems necessary to obtain lasting therapeutic effects by combining several kinds of therapeutic methods. It was emphasized that laser surgery and interferon were both powerful therapeutic means for this tenacious disease.View full abstractDownload PDF (5744K) -

JOURNAL FREE ACCESSOne of major functions of the epiglottis is thought to protect the lower respiratory tract, covering the glottis in phase of swallowing. It is most likely that the epiglottis might play an important role to make food channels bilaterally cooperating with hypopharyngeal structures in swallowing.
On the other hand, the epiglottis should stand up forward and upward in inspiratory phase in order to let the air pass the glottis smoothly.
If the epiglottis falls down backward and downward, in inspiration, dyspnea might be caused.
We have recently experienced such a patient with dyspnea. The laryngeal mirror examination revealed that the epiglottis was sucked down toward the glottis in phase of inspiration. The fluorocinematography was very useful to obtain an exact diagnosis. The epiglottis was thought to be longer than a usual one we observe clinically.
We succeeded in releasing the patient from dyspnea by partial resection of the epiglottis by use of laser under microlaryngoscopical procedure.
In this paper, the whole clinical course was reported and the merit of laser surgery for resection of the epiglottis through the direct laryngoscope was emphasized. The result was discussed from the viewpoint of anatomy of the epiglottis.View full abstractDownload PDF (3666K) -

JOURNAL FREE ACCESSWe had a patient with cancers of the tongue and the cervical esophagus. Cancers were resected and the defect in the oral cavity was primarily reconstructed with the use of PM-MC flap, and a free flap from the radial forearm was used for the reconstruction of the cervical esophagus by microvascular surgery.
We consider that the radial forearm free flap is useful for the reconstruction of the cervical esophagus.View full abstractDownload PDF (7778K) -

JOURNAL FREE ACCESSAn ectopic malignant thymoma in association with occult papillary adenocarcinoma in the thyroid, seen in a 58-year-old female, was reported. Clinically, this tumor took after a thyroid carcinoma. Thyroid scintigram using 99mTcO4- showed a cold nodule, while 201Tl radio-isotopes were markedly accumulated in the tumor lesion. Since the tumor invaded the left thyroid lobe and isthmus, recurrent nerve, trachea and esophageal muscle layer, subtotal thyroidectomy with resection of 2nd to 4th tracheal rings and partial resection of the esophageal muscle. The defective trachea was reconstructed by end to end anastomosis. Histologic examination revealed a malignant thymoma of mixed type and an occult papillary adenocarcinoma in the thyroid gland. Two year and three month follow-up showed no local recurrence and metastasis.View full abstractDownload PDF (7262K) -

JOURNAL FREE ACCESSFiberoptic bronchoscopy with conventional instruments is not feasible in infants and small children because of poor ventilation. Another limiting factor in foreign body removal presently is the small diameter of the instrument channel which precludes passage of standard grasping forceps.
To improve this situation, we devised a new flexible ventilating broncho-fiberscope.
The specifications for the new broncho-fiberscope are as follows: A light-guided system with forward viewing angle of 70°, with the outer diameter of its tip and flexible part 5.9mm and 6.1mm respectively. It has a working length of 600mm. Angulation angles are 110° upwards and 60° downwards. It has a large channel (diameter, 3mm), compared with the size of the scope.
For ventilation, we made a special adaptor, which has two connecting taps with a tube from the anesthesia machine for respiratory gases and a suction tube for aspirating secretions. By pushing the rubber cap of the adaptor, ventilation can be instantaneously switched to suction.
For removal of foreign bodies, we made a small sized fenestrated forceps which is especially suitable for grasping peanut.View full abstractDownload PDF (4467K)
