The examination of the colon, to rule out a lesion contributing to blood loss, along with an upper gastrointestinal endoscopy (gastroscopy) to rule out oesophageal, stomach, and proximal duodenal sources of blood loss. Fecal occult blood is a quick test which can be done to test for microscopic traces of blood in the stool. A positive test is ...
3. Cholecystectomy: Surgically removing the gallbladder, frequently as a result of painful gallstones or other problems. 4. Colectomy: The removal of the colon (large intestine) whole or in part.

Before removal, the portion of the bowel to be resected must be freed or mobilized. This is done by dissection and removal of the mesentery and other peritoneal attachments. Resection of any part of the colon entails mobilization and the cutting and sealing, or ligation, of the blood vessels supplying the portion of the colon to be removed. [8]
Bleeding and puncture of the colon are possible complications of sigmoidoscopy. However, such complications are uncommon. Flexible sigmoidoscopy takes 10 to 20 minutes. During the procedure, the patient might feel pressure and slight cramping in the lower abdomen, but the patient will feel better afterward when the air leaves the colon.
Significant upper gastrointestinal bleeding is considered a medical emergency. Fluid replacement, as well as blood transfusion, may be required. Endoscopy is recommended within 24 hours and bleeding can be stopped by various techniques. [1] Proton pump inhibitors are often used. [2] Tranexamic acid may also be useful. [2]
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization
