Colo-rectum: why do we not find diminutive sessile serrated polyp?

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

We describe a method to form gas hydrate on sessile water droplets to study the effects of various inhibitors, promoters, and substrates on the hydrate crystal morphology.

Here we demonstrate how to induce and monitor regeneration in the Starlet Sea Anemone Nematostella vectensis, a model cnidarian anthozoan. We demonstrate how to amputate and categorize regeneration using a morphological staging system, and we use this system to reveal a requirement for autophagy in regenerating polyp...

Polyp bail-out is a process induced by acute stress, in which coral polyps digest the tissue connecting them to their colony and detach from it to live as individuals. The present protocol describes how to induce coral micropropagation by bail-out using hypersaline or calcium-free seawater treatments.

The novel technique presented here employs a combination of 6-Fr micro-scissors and forceps for hysteroscopic treatment of endometrial polyps, demonstrating encouraging outcomes for infertile patients afflicted with this...

Vocal fold polyps can disrupt vocal fold dynamics and thus can have devastating consequences on a patient's ability to communicate. Three-dimensional flow separation induced by a wall-mounted model polyp and its impact on the wall pressure loading are examined using particle image velocimetry, skin friction line visualization, and wall pressure...
