Background And Aim: The clinical outcomes of endoscopic submucosal dissection (ESD) for gastric tube cancer (GTC) after esophagectomy remain unclear. The aim of this study was to evaluate the clinical outcomes and safety of ESD for GTC.

Patients And Methods: Twenty GTC lesions in 18 consecutive patients who underwent ESD between February 2008 and June 2018 were included in this retrospective study. The endpoints were the treatment outcomes of ESD (i.e., resection rate, complete resection rate, and curative resection rate), the adverse events following ESD, and the long-term outcomes.

Results: The resection rate was 100%, while the complete resection rate and curative resection rate were 80% each. Adverse events were observed in 16.7% (3/18) of patients: one postoperative bleeding, 1 intraoperative perforation that required emergency surgery, and 1 pyothorax that required chest drainage. The 1-, 3-, and 5-year overall survival rates were 100%, 70.9%, and 70.9%, respectively. Although local recurrence was detected in 1 case of noncurative resection, no GTC- or ESD-related deaths were observed.

Conclusion: ESD for GTC was feasible and acceptable to enable resection and to prevent cancer death. However, ESD for GTC should be performed more carefully than common gastric ESD because serious adverse events specific to the gastric tube may occur.

Successful staged surgery for advanced esophageal cancer after conversion pancreatoduodenectomy with pancreaticogastrostomy.

Clin J Gastroenterol

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Background: Benefits of neoadjuvant treatment for pancreatic cancer with major vessel invasion has been demonstrated through randomized controlled trials; however, the optimal neoadjuvant treatment strategy remains controversial, especially for radiotherapy. Therefore, we aimed to evaluate the efficacy and safety of neoadjuvant radiotherapy followed by chemotherapy and the optimal time interval to undergo surgery after radiotherapy in (borderline) resectable pancreatic cancer.

Methods: Between 2013 and 2022, patients with (borderline) resectable pancreatic cancer with vessel contact who received 5-fluorouracil with leucovorin, oxaliplatin, and irinotecan or gemcitabine and nanoparticle albumin-bound paclitaxel as initial treatment following surgery were included.

Background: Low anterior resection (LAR) is the gold standard for curative cancer treatment in the middle and upper rectum. In radically operated patients, the local recurrence rates with total mesorectal excision (TME) after 5 and 10 years was<10%, with 80% in 5 years survival. Anastomotic leakage (AL) affects 4%-20% of patients who underwent LAR.

Flurbiprofen axetil is a nonsteroidal anti-inflammatory drug used for analgesia. Its combination with dezocine has previously shown a superior postoperative analgesic effect compared with that of opioids. The present study compared the analgesic effect between dezocine plus flurbiprofen axetil (DFA) and sufentanil in patients with colorectal cancer (CRC) following resection of the tumor.

Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.

Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.
