Abstract

The introduction of total mesorectal excision and wider use of laparoscopic surgery pushed the field of colorectal surgery into an era of interfasical dissection. The Japanese suggestion of fascial arrangement of the trunk in a multilaminar, symmetrical and parallel way helps in better understanding of fascial relationship and interfascial planes surrounding the colon and the rectum. However, different interpretations of the multilayer retroperitoneal fascial relationship, complexity of fascial structures within the pelvis and dense adhesion between two apposed fasciae at special points make it still challenging for the surgeon to decide on the precise interfascial plane for colorectal mobilization. Small vessels on fasica propria of the rectum and various retroperitoneal fascia, especially ureterohypogastric fascia show distinctive features. The root of small vessels on fascia propria of the rectum helps to identify the anterolateral and posterolateral interfascial plane in the middle and low rectum. The longitudinal trajectory of small vessel on ureterohypogastric fascia and scarcity interfascial vascular communication between mesocolic and retroperitoneal fascia help the surgeon to find and stay in the interfacial plane duri...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
