In a consecutive series of 38 patients over 5 years, who required emergency surgery for obstructing left colonic carcinoma, 24 had primary bowel resection with immediate anastomosis, after intraoperative anterograde colonic irrigation. Complete colonic obstruction was present in all cases. There were 7 Dukes B tumors, 11 Dukes C tumors and 6 Dukes D tumors. The operative mortality was 8.3% (2 patients, with one from anastomotic leakage), anastomotic leakage rate was 4%. Superficial wound infection occurred in 4% of patients. The median postoperative hospital stay was 19.5 days. The Kaplan-Meier survival curve showed a 41% survival rate after 5 years. This technique was found to be safe and effective to perform a primary anastomosis, without requiring temporary colostomies, after emergency resection of selected left colonic carcinoma obstruction.

Background: Major histocompatibility complex class-1-related protein (MR1), unlike human leukocyte antigen (HLA) class-1, was until recently considered to be monomorphic. MR1 presents metabolites in the context of host responses to bacterial infection. MR1-restricted TCRs specific to tumor cells have been described, raising interest in their potential therapeutic application for cancer treatment.

The traditional treatment of colorectal cancer (CRC) involves a combination of chemotherapy and synthetic and natural drugs. In this study, a hybrid compound of 5-fluorouracil-curcumin encapsulated in bacterial nanocellulose (BNC) was evaluated for CRC treatment. Bacterial nanocellulose was produced using K.

Article Synopsis
- * A study of eight patients treated at Hospital Posadas from 2000 to 2021 found that all had mucinous adenocarcinoma, with the majority having advanced stages at diagnosis and a low 3-year survival rate of 25%.
- * No predisposing conditions were identified among the patients, highlighting the need for heightened awareness and prompt evaluation for colorectal cancer in young individuals presenting with relevant symptoms.
