Optimal cutoff value of preoperative CEA and CA19-9 for prognostic significance in patients with stage II/III colon cancer.

Purpose: This unicentric, retrospective cohort study aimed to identify the optimal cutoff values of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) for the prognosis in patients with stage II/III colon cancer.

Methods: After excluding 43 patients with CA19-9 levels < 0.2 U/mL, 588 were included.

CA19-9 is a significant prognostic marker of patients with stage III gastric cancer.

Background: Due to prognostic heterogeneity within a stage of gastric cancer (GC), identification of patients with a high risk for recurrence after resection is important. We aimed to identify the prognostic significance of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels in patients with Stage I, II, and III GC who underwent R0 gastrectomy.

Methods: A total of 794 patients were included in this study after excluding 72 patients with CA19-9 <1.

Chronological Changes in Appendiceal Pathology Among Patients Who Underwent Appendectomy for Suspected Acute Appendicitis.

Background: Given recent advances in imaging and the development of diagnostic parameters, the rate of unnecessary appendectomy (i.e., negative appendectomy) has been decreasing.

Esophageal reconstruction using a pedicled jejunum following esophagectomy for metastatic esophageal stricture from breast cancer in a patient with previous pancreatoduodenectomy.

A 71-year-old woman with dysphagia was diagnosed with thoracic esophageal squamous cell carcinoma by endoscopic biopsy at another hospital. She had previously undergone partial breast excision with axillary lymph node dissection for right breast cancer eleven years earlier and subtotal stomach-preserving pancreatoduodenectomy with Child's reconstruction for ampullary cancer ten years earlier. Gastrointestinal endoscopy showed a stricture due to a bulging submucosal tumor in the mid-thoracic esophagus.

The impact of cervical lymph node dissection on acid and duodenogastroesophageal reflux after intrathoracic esophagogastrostomy following transthoracic esophagectomy.

Purpose: The aim of this study was to evaluate the impact of cervical lymph node dissection on acid reflux and duodenogastroesophageal reflux (DGER) in patients undergoing transthoracic esophagectomy with gastric tube reconstruction and intrathoracic esophagogastrostomy.

Methods: Thirty-one patients receiving transthoracic esophagectomy with gastric tube reconstruction by intrathoracic esophagogastrostomy were divided into the following two groups: a two-field lymph node dissection group (2F group) and a three-field lymph node dissection group (3F group). All patients underwent 24-h pH and bilirubin monitoring and gastrointestinal endoscopy at 1 year after surgery.
