Article Synopsis
- Gastrointestinal subepithelial lesions (SELs) can be benign or malignant, and diagnosing them accurately using endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is challenging, especially for smaller lesions (≤ 2 cm).
- A retrospective study indicated that over 50% of patients with SELs of this size were diagnosed as gastrointestinal stromal tumors (GISTs), highlighting the necessity of using effective EUS-FNB techniques.
- This multicenter study aims to compare the effectiveness of two types of EUS-FNB needles (22G Fork-tip vs. 22G Franseen) in obtaining adequate tissue samples from SELs ≤ 2 cm, with different endpoints focusing on sample quality and procedural outcomes.
Background: This study compared short- and mid-term outcomes of hemihepatectomy (HH) and pancreatoduodenectomy (PD) in patients with extrahepatic cholangiocarcinoma, focusing on surgical outcomes, body composition, and nutritional status.
Method: A retrospective review was conducted to assess short-term outcomes, including operative time, blood loss, complications, and mortality. Body composition and nutritional parameters were analyzed preoperatively and 1 year postoperatively.
Article Synopsis
- * Patients were divided into long-TTS (≥64 days) and short-TTS (<64 days) groups, with the long-TTS group showing higher rates of preoperative biliary infections and portal vein embolization but comparable overall survival rates between the groups.
- * Despite a lower rate of potentially curative resections in the long-TTS group, TTS did not have an association with survival outcomes for those undergoing potentially curative procedures.
Background: This study aimed to determine the clinical significance of resection of pancreatic ductal adenocarcinoma diagnosed with occult para-aortic lymph node metastasis using intraoperative para-aortic lymph node sampling.
Methods: Between January 2005 and May 2021, a total of 606 patients who underwent surgery for pancreatic ductal adenocarcinoma with intraoperative para-aortic lymph node sampling were retrospectively investigated and divided into the resected para-aortic lymph node-negative (n = 543), resected para-aortic lymph node-positive (n = 44), and unresected para-aortic lymph node-positive (n = 19) groups. Overall survival, clinicopathologic characteristics, and prognostic factors were analyzed.
