Deduction of operation, holds in colorectal surgery, include good knowledge of anatomy and her connection in that area. Large bowel has special anatomy and functional mark. Intensive study of colorectal cancer bring about a new knowledge about anatomy of the large bowel, especially about vascular variations. We described the very importance characteristic of colon, rectum and anus in this article.

Human intestinal spirochaetosis is caused by the colonisation of the luminal membrane of the colon and rectum by anaerobic spirochaetes belonging to the genus Brachyspira. The common method used for its diagnosis is routine haematoxylin and eosin staining of colonic and rectal biopsy samples. The clinical spectrum of human intestinal spirochaetosis is heterogeneous, ranging from asymptomatic colonisation to symptoms such as chronic mucosal diarrhoea, rectal bleeding, and abdominal pain.

(1) Background: Volumetric modulated arc therapy (VMAT) can deliver more accurate dose distribution and reduce radiotherapy-induced toxicities for postoperative cervical and endometrial cancer. This study aims to retrospectively analyze the relationship between dosimetric parameters of organs at risk (OARs) and acute toxicities and provide suggestions for the dose constraints. (2) Methods: A total of 164 postoperative cervical and endometrial cancer patients were retrospectively analyzed, and the endpoints were grade ≥ 2 acute urinary toxicity (AUT) and acute lower gastrointestinal toxicity (ALGIT).

Background: Postoperative death measured 30 days after surgery is a conventional quality metric, whereas intervals up to 90 days are increasingly used, although data-driven time windows have scarcely been investigated.
Methods: The Swedish Colorectal Cancer Registry was used to identify all patients subjected resection for colorectal cancer between 2007 and 2020. All patients were followed up until 180 days after surgery.

Background: The colon and rectum are highly innervated, with neural components within the tumor microenvironment playing a significant role in colorectal cancer (CRC) progression. While perineural invasion (PNI) is associated with poor prognosis in CRC, the impact of nerve density and diameter on tumor behavior remains unclear. This study aims to evaluate the prognostic value of nerve characteristics in CRC and to verify the impact of nerves on tumor growth.
