The aim of this study was to assess the impact of postoperative complications after esophagectomy on long-term outcome.The treatment of esophageal cancer has recently been improved; however, esophagectomy with thoracotomy and laparotomy carries considerable postoperative morbidity and mortality. The real impact of postoperative complications on overall survival is still under evaluation.A retrospective analysis was performed on patients with esophageal cancer who underwent esophagectomy with thoracotomy and laparotomy, with R0 or R1 resection between January 1997 and December 2012. Of 402 patients, we analyzed the following parameters 284 patients who could be followed up for over 5 years: stage of disease, neoadjuvant therapies, surgical approaches, surgical complications, postoperative medical complications, and overall and relapse-free survivals using medical records.Of the 284 patients, 64 (22.5%) had pneumonia, 55 (19.4%) had anastomotic leakage, and 45 (15.8%) had recurrent laryngeal nerve paralysis (RLNP). Pneumonia had a significant negative impact on overall survival (P = 0.035); however, anastomotic leakage and RLNP did not affect overall survival. Multivariate analysis revealed that the presence of pneumonia was predictive of poorer overall survival; the multivariate hazard ratio was 1.456 (95% confidence interval 1.020–2.079, P = 0.039).Pneumonia has a negative impact on overall survival after esophagectomy. Strategies to prevent pneumonia after esophagectomy should improve outcomes in this operation.

Introduction Non-exposed endoscopic wall-inversion surgery (NEWS) is a novel technique of endoscopic fullthickness resection without transluminal access mainly designed to treat gastric cancer. Here, we report a successful case of NEWS with sentinel node basin dissection (SNBD) for early gastric cancer (EGC) with the risk of lymph node metastasis. Patient and methods A 55-year-old female patient with a 2-cm, diffuse-type intramucosal EGC with ulceration was referred to our hospital for a less invasive gastrectomy based on sentinel node navigation surgery. After obtaining informed consent, NEWS with SNBD was applied. After placing mucosal markings, indocyanine green solution was injected endoscopically into the submucosa around the lesion to examine sentinel nodes (SNs). The SN basin (the area of the left gastric artery), including three stained SNs(#3), was dissected, and an intraoperative pathological diagnosis confirmed that no metastasis had occurred. Subsequently, NEWS was performed for the primary lesion. Serosal markings were placed laparoscopically, submucosal injection was added endoscopically, and circumferential sero-muscular incision and suturing were performed laparoscopically, with the lesion inverted toward the inside of the stomach. Finally, the circumferential mucosal incision was performed, and the lesion was retrieved perorally. Results The operation was finished in 270 min without complications. The patient was uneventfully discharged 10 days after the procedure. The final pathological diagnosis was coincident with the pre-and intraoperative assessment. Conclusions We demonstrated the feasibility and safety of NEWS with SNBD with a favorable result. This surgical concept is expected to become a promising, minimally invasive, function-preserving surgery to cure cases of EGC that are possibly node-positive.

Preoperative FA score was significantly associated with postoperative survival in esophageal cancer patients, and the prognostic value is currently being validated in a prospective multicenter cohort study.
