Pancreatic enzymatic mediastinitis followed by total gastrectomy with splenectomy: report of two cases.

Background: Acute mediastinitis is a rare disease that rapidly progresses with a high mortality rate. Its most common cause is direct injury of the mediastinum, including iatrogenic causes such as cardiac surgery or upper endoscopy. Enzymatic mediastinitis is a rare complication of a pancreatic fistula caused by the inflammatory digestion of the parietal peritoneum spreading to the mediastinum.

Lethal multiple colon necrosis and perforation due to fulminant amoebic colitis: a surgical case report and literature review.

Background: Amoebiasis caused by the protozoan species Entamoeba histolytica rarely develops into fulminant amoebic colitis (FAC), but when it does, it shows an aggressive clinical course including colonic perforation, necrotizing colitis, and high mortality. Surgical treatment for FAC patients should be carried out urgently. However, even after surgery, the mortality rate can be 40-50%.

Prognostic Impact of the Neutrophil-to-Lymphocyte Ratio in Stage I-II Rectal Cancer Patients.

Background: Systemic inflammation and immune response play crucial roles in tumor growth; neutrophil-to-lymphocyte ratio (NLR) is a known systemic inflammatory scoring system. Previous studies have reported that NLR is a prognostic biomarker in various human cancers. The aim of this study was to determine whether the NLR predicts tumor recurrence in patients with stage I-II rectal cancer after curative resection.

Long-Term Outcome of Definitive Chemoradiotherapy and Induction Chemoradiotherapy Followed by Surgery for T4 Esophageal Cancer with Tracheobronchial Invasion.

Background: T4 esophageal cancer (EC) that invades the trachea or bronchus often has poorer prognosis than other T4 ECs. We investigated the long-term results of definitive chemoradiotherapy (dCRT) or induction chemoradiotherapy followed by surgery (iCRT-S) in patients with T4 EC with tracheobronchial invasion (TBI).

Patients And Methods: From 2003 to 2013, 71 patients with T4 EC with TBI were treated in our institution; 58 underwent dCRT, and 13 underwent iCRT-S.

Benefits of laparoscopic surgery compared to open standard surgery for gastric carcinoma in elderly patients: propensity score-matching analysis.
