The anal canal begins where the rectum enters the puborectalis sling at the apex of the anal sphincter complex (palpable as the anorectal ring on digital rectal examination and approximately 1 cm to 2 cm proximal to the dentate line) and ends with the squamous mucosa blending with the perianal skin (Figure 1), which coincides roughly with the palpable intersphincteric groove or the outermost ...

The transition from sigmoid to rectum is marked by the fusion of the tenia coli of the sigmoid to form the circumferential longitudinal muscle of the rectal wall approximately 12 to 15 cm from the dentate line.1 . The rectum is defined clinically as the distal large intestine commencing opposite the sacral promontory and ending at the upper ...

External hemorrhoids arise from the inferior (or external) rectal venous plexus which drains into inferior rectal veins, to the internal pudendal veins, to the internal iliac veins.

Second-degree haemorrhoids prolapse through the anus but reduce ...
