Purpose: In recent years, major advancements have been made in rectal cancer surgery with the introduction of new techniques such as robotic surgery and indocyanine green fluorescence imaging (ICG-FI). This study aimed to evaluate the comprehensive risk factors for anastomotic leakage (AL) following rectal cancer surgery, incorporating recently introduced techniques and other existing factors, to reflect current practices.
Methods: A retrospective analysis was conducted of 304 patients who underwent either robotic or laparoscopic anterior resection between January 2019 and December 2023.
Purpose: Diverting ileostomy is related to postoperative high-output stoma (HOS) leading to kidney injury. The purpose of our study was to clarify the risk factors for ileostomy-associated kidney injury, which is kidney injury starting after the first operation to ileostomy closure after colorectal tumor surgery with diverting ileostomy.
Methods: Between January 2013 and December 2020, 442 patients who underwent colorectal tumor surgery (cancer, neuroendocrine tumor, and leiomyosarcoma) following diverting ileostomy formation were included.
Nitrite-oxidizing bacteria (NOB), which perform the second step of aerobic nitrification, play an important role in soil. In the present study, we report a novel isolate from agricultural soil affiliated with the genus Nitrobacter and its physiological characteristics. We sampled the surface soil of a vegetable field and obtained mixed culture A31 using the most probable number (MPN) method with inorganic medium containing 0.

- The study compares clinicopathological characteristics and prognosis of ulcerative colitis-associated colorectal cancer (UC-CRC) and sporadic colorectal cancer (S-CRC) in patients who underwent surgery between 2000 and 2021.
- Out of 5992 surgery patients, 288 (48 with UC-CRC, 240 with S-CRC) were matched and analyzed, revealing that UC-CRC patients had more invasive surgeries and longer operative times but similar postoperative outcomes.
- Long-term survival rates were comparable overall, but stage 3 UC-CRC patients exhibited significantly poorer 5-year survival rates and different recurrence patterns compared to S-CRC patients, indicating potential prognostic differences.
