Efficacy of mediastinal lymphadenectomy in transhiatal esophagectomy with and without diaphragm opening: a cadaveric study

DISEASES OF THE ESOPHAGUS, Issue 2 2002
F. A. M. Herbella
SUMMARY., Transhiatal esophagectomy (THE) is believed to induce a lower morbidity and mortality compared with transthoracic esophagectomy, but to be inefficient in performing mediastinal lymphadenectomy. Some surgeons are convinced that lymphadenectomy of the lower mediastinum in THE and transthoracic esophagectomy are equivalent. To test this, the authors performed THE in 20 cadavers (10 with and 10 without diaphragm opening). The number of lymph nodes resected with the esophagus and dissected through the hiatus was counted. After THE, the thorax was opened and the number of residual lymph nodes was evaluated. Complications were also assessed. The results show that lymphadenectomy in THE is incomplete in the lower mediastinum and not possible in the upper mediastinum; comparing THE with and without diaphragm opening, the first permits resection of a superior number of lymph nodes with the esophagus and dissection of a higher number of nodes through the hiatus. It is concluded that THE does not provide an effective mediastinal lymphadenectomy. [source]

Transcervical superior mediastinal lymphadenectomy in the management of papillary thyroid carcinoma

Abstract Aim. Surgery is the treatment of choice for lymph node metastases in papillary thyroid carcinoma. When adequately treated by surgical extirpation, the presence of lymph node involvement does not seem to have a negative impact on cure rates or survival. Surgical lymphadenectomy for metastatic papillary thyroid carcinoma has been well described for both the central and the lateral compartments of the neck. Superior mediastinal lymphadenectomy, however, has only sporadically been mentioned. We describe our experience with transcervical superior mediastinal lymphadenectomy (TSML) that avoids the morbidity of the traditional sternal split. Materials and Methods. This retrospective analysis included 30 patients (24 women and 6 men; age range, 17,72 years) who underwent TSML by the senior author (JLF) for papillary carcinoma metastatic to the superior mediastinum between 1985 and 1999. Histopathologic examination confirmed positive nodes in all the mediastinal dissections. All patients received postoperative I131. Results. All the patients are alive after a median follow-up of 5 years (range, 1,14 years). Twenty-nine of 30 patients remain free of disease, whereas one patient is alive with lung and bone metastases. No patient has had local or regional relapse. The only significant complication was a high incidence of temporary (70%) and later permanent (50%) hypoparathyroidism. Conclusions. TSML is a safe and effective treatment for superior mediastinal metastases in papillary thyroid carcinoma. © 2002 Wiley Periodicals, Inc. Head Neck 24: 000,000, 2002 [source]
