Article Synopsis
- A study reviewed 13 patients with colonic stenosis caused by non-colorectal extracolonic cancers between July 2012 and January 2018, involving mainly older adults with various types of cancers.
- *The technical success rate of endoscopic stenting in these non-CRC patients (69%) was significantly lower compared to those with colorectal cancer (98%) and those who were preparing for surgery (99%).
- *Despite the lower success rates, endoscopic stenting provides a minimally invasive option that can offer quick relief for patients suffering from colonic stenosis due to extracolonic malignancies.
We experienced a case of low-grade appendiceal mucinous neoplasm complicated by pseudomyxoma peritonei that was successfully treated with cytoreductive surgery and early postoperative intraperitoneal chemotherapy. The patient was a 26- year-old man with massive ascites and a swollen appendix on the computed tomography(CT). The appendix was a cystic mass of 5 cm in size.

- The study aimed to evaluate the effectiveness of selective lateral pelvic lymph node dissection (LPLD) for patients with advanced low rectal cancer who received pre-operative chemoradiotherapy (CRT).
- Researchers reviewed data from 32 patients who had no signs of lateral lymph node (LPLN) metastasis on imaging before treatment and underwent total mesorectal excision (TME) without LPLD.
- Findings showed tumor recurrence in 14 patients, but none of the recurrences occurred in the lateral lymph node areas, suggesting that lateral dissection may not be necessary for these patients.
We report the case of a 55-year-old man who successfully underwent resection of a recurrence of ulcerative colitis(UC)- associated colon cancer located in the pancreatic body and left kidney. The patient had undergone an emergency laparotomy (total proctocolectomy with stapled ileal-pouch anal anastomosis)for the treatment of a descending colon cancer with retroperitoneal penetration associated with UC at the age of 50 years. At that time, histological examinations revealed a mucinous carcinoma that was classified as Stage II colon cancer.
