The purpose of this study was to investigate the correlation between the oculocardiac reflex (OCR) and blepharoptosis surgery for safe eyelid surgery. Fifty-four consecutive patients with bilateral aponeurotic blepharoptosis were enrolled in this study. Changes in electrocardiography (ECG) monitoring were recorded during surgery. Preoperative pressing on the globe and intraoperative stretching of the levator aponeurosis were also carried out and the occurrence rate of the OCR was recorded. A positive OCR was observed in 12 patients (22.2%) in the preoperative globe-pressing test, whereas a positive OCR was observed in 22 patients (40.7%) in the levator-stretching test. The levator-stretching test did not indicate a significant difference in the rate of heart rate decrease with respect to laterality. No correlation was observed between age and the occurrence of OCR. On the other hand, there was a significant difference in the percentage of heart rate decrease between patients with positive OCR and negative OCR as determined in the globe-pressing test (mean = 13.1% vs. 5.4%). During the practical operative manoeuvre, no bradycardia was observed in any case. This study confirmed that a rapid and strong traction of levator aponeurosis induces the OCR regardless of laterality and age. Atraumatic and gentle handling are essential to prevent OCR. The preoperative globe-pressing test may be an index of the OCR in reflex-prone patients. Intraoperative ECG monitoring will be useful for early onset detection, although positive OCR was not observed in any patient during the practical surgical manoeuvre.

We report a case of tracheoesophageal fistula (TEF) secondary to chemotherapy for primary thyroid lymphoma. A 65-year-old man with a short history of a rapidly enlarging neck mass was diagnosed as having thyroid lymphoma of diffuse, large B-cell type. The TEF occurred during the first course of chemotherapy including cyclophosphamide, doxorubicin, vincristine and prednisolone. After placing a feeding gastrostomy without oral intake, eight cycles of chemotherapy were completed and complete remission was achieved. Although the cervical mass disappeared, TEF and esophageal stenosis persisted. Total thyroidectomy and resection of the stenotic cervical esophagus were carried out followed by interposition of the revascularized jejunum and its mesenteric patch to cover the TEF. This seems to be the first report of a TEF caused by chemotherapy for primary thyroid B-cell lymphoma. A variety of treatments for TEF including simple closure, tracheal resection, colonic bypass and muscle flap have been reported with low success rates. Our procedure using a jejunal mesenteric patch seems to be unique and may be a new treatment strategy for TEF.
