Elective colorectal cancer surgery in nonagenarians and postoperative outcomes.

Objectives: The population of very elderly patients is increasing, and nonagenarians have significantly higher mortality rates and poorer rates of survival than younger patients. Meanwhile, recent studies have shown colorectal cancer surgery in nonagenarian patients to be feasible regarding postoperative outcomes. This retrospective study aims to evaluate the postoperative outcomes of nonagenarians in the latest clinical settings.

What is related to postoperative outcome of frail status in elective colorectal cancer surgery?

Background: The population affected by colorectal cancer is growing, and there is an increasing need for prevention of functional decline following treatment. We proposed that the Kihon Checklist published by the Japanese Ministry of Health, Labor, and Welfare would be an appropriate means of frailty assessment for prediction of postoperative complications in older patients with colorectal cancer. This prospective cohort study aims to identify the factors influencing postoperative frailty.

Asymptomatic patent processus vaginalis is a risk for developing external inguinal hernia in adults: A prospective cohort study.

Background: Inguinal hernia repair is common for children and adults across the world, but the mechanism behind hernia onset still requires elucidation. This prospective study aims to determine whether patent processus vaginalis (PPV) is a factor in the development of external inguinal hernias.

Method: We enrolled 1008 patients who underwent laparoscopic surgery and in whom the inguinal region was observed.

Optimal Assessment of Frailty Predicts Postoperative Complications in Older Patients with Colorectal Cancer Surgery.

Objectives: The increasingly elderly worldwide population has affected the incidence of colorectal cancer. Establishment of reliable assessment of frailty and proposals for multi-disciplinary interventions are urgently required in oncology practices. Kihon Checklist (KCL) was published by the Japanese Ministry of Health, Labor and Welfare originally to identify individuals ≥ 65 years old at probable risk for requiring care or social support.
