Background: Undifferentiated pleomorphic sarcoma (UPS) is a malignant soft tissue tumor that has been reclassified from malignant fibrous histiocytoma with the development of the pathological diagnosis. It principally occurs in the extremities but rarely occurs in the rectum. We herein report a rare case of UPS arising in the rectum.

Patients And Methods: Between 2012 and 2015, 113 patients with mCC who underwent chemotherapy according to the Japanese Colorectal Cancer Treatment Guidelines at four Jikei University Hospitals were enrolled in this study. The two serum tumor makers, CEA and CA19-9 were measured before first-line chemotherapy and at four months thereafter.
Background And Purpose: We started performing sentinel node navigation surgery (SNNS) for patients with early gastric cancer (EGC) using infrared ray electronic endoscopy (IREE) with indocyanine green injection from year 2000. The EGCs usually have complex lymphatic drainage, unidirectional or multidirectional lymphatic flow. In this study, we investigated and clarified factors that affect the direction of gastric lymphatic drainage.

Background/aim: To determine the superiority of the laparoscopic vs. open technique for colorectal cancer surgery.
Patients And Methods: We performed a retrospective analysis of consecutive patients who underwent curative surgery by laparoscopic colectomy (LC) or open colectomy (OC) for colon cancer.
Article Synopsis
- The study aimed to assess the safety of different anastomotic methods used during colon surgery by analyzing complications that arise from these techniques.
- Researchers looked at 684 cases from 2003 to 2013, evaluating complications like leakage, stricture, and bleeding based on three methods: hand-sewn (HS), functional end-to-end (FEEA), and triangulating (TRI) anastomosis.
- The findings indicated that TRI had a significantly lower incidence of anastomotic leakage compared to HS and FEEA, suggesting that TRI may be a safer option in colon surgeries.
Background/aim: The aim of this study was to evaluate the necessity of thoracic epidural analgesia (TEA) as enhanced recovery after surgery (ERAS) programs for laparoscopic colorectal surgery (LC).
Patients And Methods: We retrospectively compared between perioperative outcomes of patients who underwent LC with TEA (n=31) and with multimodal analgesia (MMA) (n=31). Furthermore, we also evaluated the patients' satisfaction by a questionnaire survey to the nurses.
