RESUMO
Mid-pancreatectomy combined with end-to-end anastomosis is a surgical procedure used to treat benign pancreatic tumors. It involves removing the tumor from the middle section of the pancreas and connecting the proximal and distal ends through an anastomosis. The traditional surgical approach for resecting the middle segment of the pancreas involves closing the proximal pancreas and creating a Roux-en-Y anastomosis with the jejunum. However, this approach carries a double risk of pancreatic stump fistula and pancreatico enteric anastomotic leak postoperatively. In this paper, a new procedure is described where stent tubes were placed into the proximal and distal sides of the pancreatic ducts after ensuring sufficient freedom from the proximal distal pancreas. The pancreatic parenchyma was then sutured continuously under direct vision to achieve pancreatic end-to-end anastomosis. This procedure helps preserve pancreatic function, reducing the risk of postoperative pancreatic insufficiency. However, due to the complexity and risks involved, thorough evaluation and preparation are necessary before surgery. We carefully assess the patient's history, serology, and imaging results to determine the feasibility and effectiveness of the procedure. During surgery, we consider the use of a suitable pancreatic duct stent to ensure the flow of pancreatic juice into the intestine through physiological pathways. Our goal is to remove the tumor while preserving as much normal pancreatic tissue as possible for the anastomosis. After the operation, it is crucial to monitor the patient's pancreatic function, paying close attention to blood glucose levels, drainage fluid volume, and amylase value of the pancreatic anastomosis. During the postoperative follow-up visit, the patient's pancreatic function was assessed, and there was no significant change in quality of life compared to before the surgery. This indicates that mid-pancreatectomy combined with end-to-end anastomosis is a safe and effective procedure for treating pancreatic benign neoplasms.

Objectives: Gastric cancer with liver metastasis (GCLM) is highly aggressive and has a poor prognosis. This study aims to evaluate the survival benefit of primary tumor resection (PTR) for gastric cancer with liver metastasis. Methods: Data on patients with GCLM was extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015. A 1:1 propensity score matching (PSM) analysis was performed to minimize the heterogeneity between the PTR and no-PTR groups. The Kaplan-Meier method and Cox regression analysis were used to assess the impact of primary tumor resection (PTR) on overall survival (OS) and cause-specific survival (CSS). Results: A total of 3,001 patients with GCLM were included, with 328 patients treated with primary tumor resection (PTR), whereas the other 2,673 patients were not. Patients with PTR had a significantly higher OS and CSS rate than those without PTR in unmatched and PSM cohorts. In an unmatched cohort, the median OS was 12.0 months (95% CI, 10 months to 14 months) for those who underwent PTR and 4 months (95% CI, 4 months to 5 months) for those without PTR; the median CSS for those who underwent PTR was 12.0 months (95% CI, 10 months to14 months) and 4 months (95% CI, 4 months to 5 months) for those without PTR, respectively. After PMS, the median OS was 12.0 months (95% CI, 10 months to 17 months) for those who underwent PTR and 7 months (95% CI, 5 months to 10 months) for those without PTR, respectively; the median CSS for those who underwent PTR was 12.0 months (95% CI, 11 months to 17 months) and 7 months (95% CI, 5 months to 8 months) for those without PTR, respectively. In addition, multivariate Cox analysis in the PSM cohort showed that PTR, age, degree of tumor differentiation, and chemotherapy were independent prognostic factors for OS and CSS in GCLM. Specifically, PTR was a significant protective factor for OS (HR: 0.427; 95% CI, 0.325 to 0.561, P <0.001) and CSS (HR: 0.419; 95% CI, 0.313 to 0.561, P <0.001). Conclusion: Primary tumor resection improves the survival of gastric cancer patients with liver metastasis.
