[Surgical Outcomes of Colorectal Cancer for Over 90-Year-Old Patients in Our Hospital].

The aim of this study was to investigate the short-term outcomes of surgery for colorectal cancer(CRC)in the elderly aged over 90 years old. We retrospectively analyzed 1,043 patients with stage Ⅰ-Ⅳ CRC who underwent curative surgery in our institutions between 2013 and 2022. The patients were divided into the super older(aged ≥90 years, 20 patients) and non-super older groups(aged 80-89 years, 243 patients). The short-term outcomes were compared between the 2 groups. There were no significant differences in tumor location, stage, surgical approach, duration of operation and blood loss. The incidence of severe postoperative complications did not differ between the 2 groups. In conclusion, our study suggested that surgery for colorectal cancer could be as safely performed in super elderly patients as in non-super elderly patients.

[Laparoscopic Surgery for Delayed Chylous Ascites in Unresectable Gastric Cancer Patient-A Case Report].

Chylous ascites is a rare post operative complication after gastrectomy, which commonly occurs in early postoperative period. Here, we successfully treated a patient with unresectable gastric cancer who occurred chylous ascites 9 months after first surgery and underwent laparoscopic surgery for chylous ascites. Since prolonged chylous ascites may cause malnutrition, surgical treatment should be considered for refractory chylous ascites.

Laparoscopic Surgery for Elderly Colorectal Cancer Patients With High American Society of Anesthesiologists Scores.

BACKGROUND/AIM: To evaluate the safety of colorectomy in elderly colorectal cancer patients with high American Society of Anesthesiologists (ASA) scores compared to those with low scores. PATIENTS AND METHODS: Two hundred patients with stage I-IV colorectal cancer aged ≥80 years were retrospectively analyzed. Short- and long-term outcomes were compared between 136 patients with ASA scores ≤2 (low ASA group) and 64 patients with scores ≥3 (high ASA group). RESULTS: The incidence of postoperative complications, duration of postoperative hospital stay, and 5-year overall and cancer-specific survival rates did not differ significantly between the groups. Laparoscopic surgery was significantly associated with a lower incidence of postoperative complications than open surgery in the high ASA score group (p=0.041), whereas no difference was observed in the low ASA score group (p=0.639). In the high ASA group, open surgery (p=0.024) and higher body mass index (p=0.040) were independent risk factors for postoperative complications. CONCLUSION: Colorectal cancer resection can be safely performed in elderly patients with high ASA scores. Moreover, laparoscopic surgery may have a stronger contribution to the reduction of postoperative complications in elderly patients with colorectal cancer with high ASA scores than in those with low ASA scores.

[A Case of an Advanced Gastric Cancer Patient with Outlet Obstruction and Malnutrition Who Successfully Underwent Neoadjuvant Chemotherapy with Enteral Nutrition].

We reported a case of an advanced gastric cancer patient with gastric outlet obstruction and malnutrition who successfully underwent neoadjuvant chemotherapy with enteral feeding. The patient is a 72-year-old man. The diagnosis was advanced gastric cancer with pyloric stenosis. Both decompression and enteral nutrition was performed with a W-ED®. Chemotherapy was markedly effective and nutritional status improved. He underwent robot-assisted distal gastrectomy(D2)and Billroth Ⅱ reconstruction under good nutritional status after neoadjuvant chemotherapy with intragastric decompression and nutritional management using a W-ED® tube. W-ED® tube is a useful tool for the proper nutritional management of patients with advanced gastric cancer who have pyloric stenosis by adequate decompression and enteral feeding.
