Sleeve resections with unprotected bronchial anastomoses are safe even after neoadjuvant therapy


Storelli, Erica; Tutic, Michaela; Kestenholz, Peter; Schneiter, Didier; Opitz, Isabelle; Hillinger, Sven; Weder, Walter (2012). Sleeve resections with unprotected bronchial anastomoses are safe even after neoadjuvant therapy. European Journal of Cardio-Thoracic Surgery, 42(1):77-81.

Abstract

OBJECTIVES: Sleeve resection is the operation of choice in patients with centrally located tumours, in order to avoid a pneumonectomy. Most surgeons protect the bronchial anastomoses with tissue to prevent insufficiencies. The purpose of this study is to report on outcome of unwrapped bronchial anastomoses, especially after neoadjuvant chemo- or chemoradiotherapy.
METHODS: Between 2000 and 2010, 103 patients [59 years (range 16-80), 40 females] underwent bronchial sleeve resections without coverage of the anastomosis with a tissue flap. We retrospectively reviewed the data for morbidity, mortality and survival, especially with regard to the type of resection, neoadjuvant therapy and stage.
RESULTS: Sleeve lobectomy was performed in 88, sleeve bilobectomy in 8, sleeve pneumonectomy in 4 and sleeve resection of the main bronchus in 3 patients. Twenty-seven patients had a combined vascular sleeve resection. Neoadjuvant chemotherapy was performed in 20 and radiochemotherapy in 5 patients. Non-small cell lung cancer (NSCLC) was present in 76 patients (squamous cell carcinoma in 44, adenocarcinoma in 24, large cell carcinoma in 6 and mixed cell in 2) and neuroendocrine tumour in 20 and other histological types in 7 patients. The pathologic tumour stage in NSCLC was stage I in 26, stage II in 26, stage IIIA in 16, stage IIIB in 7 and stage IV in 1 patient. There were no anastomotic complications, especially no fistulas. One patient developed narrowing of the intermediate bronchus without need for intervention. Twenty-four patients had early postoperative complications, including 11 surgery-related complications (air leakage, nerve injury, haemothorax or mediastinal emphysema). The 30-day mortality was 3% (one patient died due to heart failure and two with multiorgan failure). The 5-year survival rate was 63% in NSCLC patients and 86% in neuroendocrine tumour patients.
CONCLUSIONS: Sleeve resection without wrapping the bronchial anastomoses with a tissue flap is safe even in patients who underwent neoadjuvant chemo- or chemoradiotherapy. Therefore, wrapping of the bronchial anastomoses is not routinely mandatory.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
