Conversion surgery for esophageal and esophagogastric junction cancer.

As a result of the recent advances in first-line treatment including chemotherapy, radiation therapy, targeted therapy, and immune checkpoint inhibitor immunotherapy (ICI) for locally advanced/metastatic initially unresectable esophageal and esophagogastric junction cancer, surgery aiming at cure after initial treatment, so-called "conversion surgery" has become more common in this field. Several studies have indicated encouraging survival outcomes for patients after conversion surgery with R0 resection. However, various issues, such the utility and the safety of conversion surgery remain unclear.

Modification of the lesser curvature incision line enhanced gastric conduit perfusion as determined by indocyanine green fluorescence imaging and decreased the incidence of anastomotic leakage following esophagectomy.

Aim: This study aimed to investigate the effectiveness of a modified incision line on the lesser curvature for gastric conduit formation during esophagectomy in enhancing the perfusion of gastric conduit as determined by indocyanine green fluorescence imaging and reducing the incidence of anastomotic leakage.

Methods: A total of 272 patients who underwent esophagectomy at our institute between 2014 and 2022 were enrolled in this study. These patients were divided based on two different types of cutlines on the lesser curvature: conventional group (n = 141) following the traditional cutline and modified group (n = 131) adopting a modified cutline.

Immunotherapy for esophageal cancer: Where are we now and where can we go.

Immune checkpoint inhibitor therapy has dramatically improved patient prognosis, and thereby transformed the treatment in various cancer types including esophageal squamous cell carcinoma (ESCC) in the past decade. Monoclonal antibodies that selectively inhibit programmed cell death-1 (PD-1) activity has now become standard of care in the treatment of ESCC in metastatic settings, and has a high expectation to provide clinical benefit during perioperative period. Further, anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) monoclonal antibody has also been approved in the treatment of recurrent/metastatic ESCC in combination with anti-PD-1 antibody.

Thoracoscopic McKeown esophagectomy in a patient with an azygos lobe.

Background: The azygos lobe is a relatively rare anatomical variation, and there have been no reports, until date, of thoracoscopic McKeown esophagectomy for esophageal cancer in a patient with an azygos lobe. The azygos lobe can be diagnosed by chest X-ray or CT, and is usually not associated with any symptoms. However, surgeons should be aware that transthoracic surgical procedures in patients with an azygos lobe could be associated with a high risk of complications.
