Laparoscopic assisted endorectal pull-through colon is minimally invasive surgery for Hirschsprung's disease; the part of the colon that does not have nerve cells is pulled through the anal canal and cut away, while the healthy end is sutured to the rectum. In addition to anal, surgical instruments, and a narrow lighted instrument with a video camera at the end (laparoscope) is inserted into the abdomen through four holes to mobilize the colon. Also known as • Colon repositioning • Laparoscopic…

prolapse is protuberance of rectal tissue via the anus to the exterior of the body. The rectum is the final segment of the large intestine. Description Rectal prolapse can be partial or complete. In partial prolapse, only the mucosa layer (mucous membrane) of the rectum spreads outside the body. The projection is usually 0.75-1.5 in (2-4 cm) long. In complete prolapse, named procidentia, the full thickness of the rectum obtrudes for up to 4.5 in (12 cm). Rectal prolapse is most common in…

Colorectal cancer is a type of cancer that is caused by the uncontrolled growth of malignant (cancerous) cells in the inner lining of the colon or rectum. The colon and rectum, also known as the large intestine, are parts of the digestive system. The primary function of the large intestine is to absorb water and excrete solid waste. The wall of the colon and rectum is composed of several layers. Colorectal cancer begins in the innermost layer of the wall (the mucosa) and can spread outward into…

The mouth which is also called the oral cavity is associated with the accessory organs such as teeth, salivary glands, and tongue. The mouth is where digestion starts. Our teeth are used to chew food into really small pieces and our saliva contains enzymes that begins the process of digestion. Our tongue occupies the floor of the mouth and mixes food with saliva to form bolus which is a compact mass that forms food into a lump that helps initiates swallowing. The mouth begins the process of…

One of the three type is External Beam Radiation therapy which is mostly used in rectum. Some of the several type of external beam therapy are Three Dimensional Conformal Radiation Therapy (3D-CRT), Intensity Modulated Radiation Therapy (IMRT), Proton Beam Therapy, Neutron Beam Therapy, Image Guided Radiation Therapy (IGRT), Stereotactic…

(WebMD). When the colon or rectal cancer spreads through the body, it is often found in the liver, sometimes found in the lungs, bones and other organs of the body. Colorectal cancer often happens when cells that are not grown normally in your colon or rectum, these cells are grown together and forms polyps, which are “benign growths (noncancerous tumors or neoplasms) involving the lining of the bowel” (American Society for Gastrointestinal Endoscopy). Over time, some of the polyps can turn into…

Heterotrophs are sectioned off into three different categories based on their intake of food. Heterotrophs are organisms that use organic compounds for energy and carbon. Herbivores, being animals that eat plants are; algae-eating snails, sapsucking insects, and vertebrates such as cows, horses, rabbits, and sparrows. Carnivores, animals who eat other animals; crabs, squid, many insects, cats, eagles, trout, and frogs. Omnivores, animals who eat both plants and other animals are; humans, pigs,…

challenge and shift the heteronormative systems of society (“Queer Histories”). Leo Bersani and Eve Kosofsky Sedgwick are two queer Authors who have impacted the public and academic structures of knowledge during this crisis. Examining Bersani’s “Is the Rectum a Grave?” and Sedgwick’s “Epistemology of the Closet,” both are positioned towards different audiences and found to converge and diverge from each other in the historically contingent need for justification of homosexual identity during…

longer bowel where it becomes solid faces. The colon is divided into three sections – Ascending, transverse and descending colon. The solid faces are collected at the end of the colon called the rectum. Bowel cancer is developed from polyps; these are tiny growths which are hidden deep inside the rectum. However, not all polyps are cancerous. Furthermore, there…

are missing from part of the large intestine (colon). The colon absorbs fluids and holds stool so that it can be passed out of the body with movements called contractions. In Hirschsprung disease, the colon has trouble moving stool out through the rectum. This leads to constipation. This condition is most commonly diagnosed at birth or shortly after. What are the causes? The cause of this condition is not known. It tends to run in families. In children who have the disease, it is present from…
