Esophagectomies have a high morbidity rate, mainly related to pulmonary complications. The aim of this work was to assess whether the thoracoscopic approach could reduce this morbidity. We have made a prospective study of the results of 29 attempts of esophagectomy using a right thoracoscopic approach. There were 20 males and 9 females having an average age of 47. The indication was a squamous cell carcinoma in 22 patients, an adenocarcinoma in 1 patient, a melanoma in 1 patient, and a caustic stenosis in 5. The whole esophagus was mobilized thoracoscopically and the esophagectomy was completed through the abdomen. The reconstruction was achieved using a gastric pull-through and a cervical anastomosis. There were five failures for the following reasons: unresectable carcinoma (one case), large tumor making a thoracoscopic dissection unsafe (two cases), and incomplete lung collapse making the exposure of the posterior mediastinum difficult (two cases). The average time of the thoracoscopic procedure was 135 min. The postoperative course was uneventful in all but five patients who had a pulmonary complication: atelectasis (three cases), right purulent pleural effusion (one case), acute respiratory disease syndrome (one case). The latter complication was lethal. Four out of five respiratory complications occurred in patients for whom the dissection was considered difficult. Among the other complications, there were five anastomotic leakages and three cases of laryngeal nerve palsy. The mortality rate was 3.8%. These initial results do not show a real benefit of the thoracoscopic approach for esophageal dissection, especially with respect to difficult esophagectomies. Further evaluation of the technique is needed.

Reoperation for persistent primary hyperparathyroidism is possible and may be easier within days of an initially unsuccessful procedure. With the intact 1-84 parathyroid hormone measurement, the diagnosis is accurate. Single-tracer 99mTc Sestamibi scintigraphy with FADS and SPECT is non-invasive, easily and rapidly performed, and was accurate in these six patients.
