Primary tracheobronchial necrosis after esophagectomy: A nationwide multicenter retrospective study in Japan.

Background: The clinical features of postoperative primary tracheobronchial necrosis (P-TBN; the necrosis without anastomotic leakage or other cervical and mediastinal abscess) remains unclear. This nationwide multicenter retrospective study first investigated the clinical features of P-TBN after esophagectomy for upper aerodigestive tract cancer with a large cohort.

Methods: As a study of the Japan Broncho-Esophagological Society, a nationwide questionnaire survey was conducted in 67 institutions.

Impact of preoperative skeletal muscle mass and physical performance on short-term and long-term postoperative outcomes in patients with esophageal cancer after esophagectomy.

Background: In patients with esophageal cancer who undergo esophagectomy, preoperative skeletal muscle mass loss has been reported to be associated with postoperative complications and poor prognosis. However, physical performance has not been fully investigated.

Methods: This study included 363 patients who underwent esophagectomy for thoracic esophageal cancer in 2013-2018.

Risk factors and long-term postoperative outcomes in patients with postoperative dysphagia after esophagectomy for esophageal cancer.

Aim: Dysphagia is one of the most common complications after esophagectomy. However, no study has investigated the long-term postoperative outcomes in patients with postoperative dysphagia. Here, we aimed to identify risk factors for postoperative dysphagia and to investigate long-term postoperative outcomes in such patients.

A Nationwide Survey on Digestive Reconstruction Following Pharyngolaryngectomy With Total Esophagectomy: A Multicenter Retrospective Study in Japan.

Aim: Digestive reconstruction after pharyngolaryngectomy with total esophagectomy (PLTE) remains challenging, with the optimal method remaining unclear. The current study aimed to clarify the short-term outcomes after PLTE and determine the optimal digestive reconstruction method.

Methods: Based on a nationwide survey of 151 patients who underwent PLTE, outcomes of digestive reconstruction methods are described.

Comparison of the modified Collard and hand-sewn anastomosis for cervical esophagogastric anastomosis after esophagectomy in esophageal cancer patients: A propensity score-matched analysis.

Background: Several studies have reported that modified Collard anastomosis is useful for cervical anastomosis after esophagectomy for thoracic esophageal cancer. However, no large-scale study has confirmed the efficacy of the modified Collard anastomosis.

Methods: Between 2008 and 2016, 398 consecutive esophageal cancer patients who underwent esophagectomy and cervical anastomosis were enrolled in this study.

Clinical usefulness of a perioperative bacteriological culture to treat patients with postoperative pneumonia after esophagectomy.

Aim: The aim of the present study was to examine the usefulness of a perioperative bacteriological culture in predicting the pathogenic bacteria responsible for postoperative pneumonia after esophagectomy.

Methods: This study included 293 consecutive esophageal cancer patients who underwent esophagectomy with gastric conduit reconstruction. We compared the pathological bacteria that were detected in bacteriological cultures of sputum, mouthwash and gastric fluid on the second postoperative day with the pathogenic bacteria responsible for postoperative pneumonia.
