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.

Randomized clinical trial comparing long-term quality of life for Billroth I versus Roux-en-Y reconstruction after distal gastrectomy for gastric cancer.

Background: Patients' quality of life (QoL) deteriorates remarkably after gastrectomy. Billroth I reconstruction following distal gastrectomy has the physiological advantage of allowing food to pass through the duodenum. It was hypothesized that Billroth I reconstruction would be superior to Roux-en-Y reconstruction in terms of long-term QoL after distal gastrectomy.

Successful resection of pancreatic carcinoma recurrence in the remnant pancreas after a pancreaticoduodenectomy.

We present a rare case in which a pancreatectomy was performed for a recurrent tumor in the remnant pancreas after a pancreaticoduodenectomy, and we review the associated literature. A 67-year old man underwent pancreaticoduodenectomy for pancreatic cancer on April 9, 2003. The tumor was composed of well differentiated adenocarcinoma and diagnosed as R0, pT2, pN1, pM0, pStage III according to UICC TNM classification.

Establishment and analysis of biological characteristics of a human duodenal carcinoma cell line, WDC-1.

Background: Duodenal carcinoma is very rare and its culture cell lines have rarely been established.

Methods: Tumor cells separated from a surgically resected primary tumor of duodenal carcinoma were put into culture. The patient was an 81-year-old female and had metastatic lymph nodes.

Reconstruction with bilateral gluteus maximus myocutaneous rotation flap after wide local excision for perianal extramammary Paget's disease. Report of two cases.

Purpose: Extramammary Paget's disease is a rare dermatosis. Wide local excision is recommended in patients with perianal extramammary Paget's disease. After wide local excision, it is necessary to do reconstruction, with preservation of bowel function.

Primary torsion of the greater omentum.

A case with primary torsion of the greater omentum is reported. This pathological condition is an uncommon cause of acute abdominal emergency and it is very difficult even for general surgeons to differentiate this from other acute abdomen. The etiology remains unknown and the treatment of choice is resection of the affected organ.
