2026
Laparoscopic surgery is widely used in the treatment of right-sided colon cancer and offers numerous advantages. This paper describes the caudal-to-cranial surgical approach combined with complete mesocolic excision (CME) and D3 lymph node dissection, which may potentially reduce the technical difficulty and appear to be a safe approach.

Laparoscopic Anatomic S7+S8d Resection Preserving Inferior Right Hepatic Vein and S6 with Right Hepatic Vein Transection

2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.
FAQs
Blood moves through the vessel from tissues located toward the tail back toward the trunk. This direction provides a route for venous return from posterior regions and connects tail circulation with the fish’s central circulation. Its position therefore helps relate external body anatomy to the internal pathway that ultimately directs blood toward the heart.
After leaving posterior tissues, venous blood may pass through the fish’s renal portal system before reaching the heart. This connection makes the caudal peduncle vein relevant to studies that trace how blood from the tail is routed through internal organs. It also links regional anatomy with broader investigations of circulation and physiological adaptation.
The caudal peduncle forms the narrow connection between the fish’s body and tail, so a vein in this region provides an anatomical reference for posterior blood return. Identifying that position helps researchers interpret how tail tissues connect with the trunk and distinguish local vascular relationships during studies of fish anatomy and circulation.
Its connections show how circulation accommodates the transition between the tail, the caudal peduncle, and the trunk. Studying this pathway can therefore place regional blood return within the larger organization of fish circulation. That anatomical context supports investigations of how body structure and blood flow relate to physiological adaptation in different fish conditions.
Veterinary examinations can use knowledge of this vessel’s location and connections when assessing fish health. The vein is relevant when researchers evaluate disease, stress, or overall systemic condition, because observations or samples associated with this region can be interpreted alongside the fish’s anatomy and circulation rather than as an isolated anatomical feature.
The caudal peduncle vein is relevant to blood collection procedures and aquaculture health assessment. Samples or examinations connected with this vessel can support evaluation of disease, stress, and systemic condition. Understanding the nearby anatomy helps researchers relate findings from the caudal region to venous return and the broader physiological status of the fish.
