RESUMO
Purpose@#Colorectal cancer (CRC) occurs in all age groups, and the application of treatment may vary according to age. The study was designed to identify the characteristics of CRC by age. @*Methods@#A total of 4,326 patients undergoing primary resection for CRC from September 2006 to July 2019 were reviewed. Patient and tumor characteristics, operative and postoperative data, and oncologic outcome were compared @*Results@#Patients aged 60 to 69 years comprised the largest age group (29.7%), followed by those aged 50 to 59 and 70 to 79 (24.5% and 23.9%, respectively). Rectal cancer was common in all age groups, but right-sided colon cancer tended to be more frequent in older patients. In very elderly patients, there were significant numbers of emergency surgeries, and the frequencies of open surgery and permanent stoma were greater. In contrast, total abdominal colectomy or total proctocolectomy was performed frequently in patients in their teens and twenties. The elderly patients showed more advanced tumor stages and postoperative ileus. The incidence of adjuvant treatment was low in elderly patients, who also had shorter follow-up periods. Overall survival was reduced in older patients with stages 0 to 3 CRC (P<0.001), but disease-free survival did not differ by age (P=0.391). @*Conclusion@#CRC screening at an earlier age than is currently undertaken may be necessary in Korea. In addition, improved surgical and oncological outcomes can be achieved through active treatment of the growing number of elderly CRC patients.
RESUMO
BACKGROUND: In this era of donor shortage, use of organs from living donors has increased significantly. Nonetheless, less than 1% of pancreas transplantations involve living donors, despite the immunological benefits, reduced cold ischemic time, and decreased waiting time. One reason for the paucity of donors is the high morbidity after open surgery. Using hand-assisted laparoscopic donor surgery (HALDS) can be a favorable technique for living donors. METHODS: Using HALDS, we performed three Simultaneous pancreas-kidney transplantations (SPKs) involving living donors. Two donors were women; one was a man. RESULTS: Their mean age was 34.3±4.7 years, and their body mass index was 23.2±2.36 kg/m². The mean operation time was 241±19.0 minutes and the mean cold-ischemic time of the kidney was 42.7±9.8 minutes, while that of the pancreas was 64.3±5.2 minutes. One donor developed a pancreatic fistula, which was controlled using conservative management. The donors' pancreatic and renal functions were well preserved postoperatively. CONCLUSIONS: HALDS for SPKs can be performed without significant complications if the surgeon has sufficient skill.
