What is a sigmoid fixation?
A sigmoid fixation is a surgical technique used in the treatment of sigmoid volvulus, a condition where the sigmoid colon twists, leading to obstruction. This procedure typically involves detorsion of the twisted bowel and may include a fixation of the sigmoid colon to the lateral abdominal wall to prevent recurrence. It aims to alleviate symptoms and restore normal bowel function while minimizing the risk of future episodes.
Does a colonoscopy view the sigmoid colon?
Yes. A colonoscopy views the entire colon. It passes from the anus to the rectum, sigmoid colon, descending colon, transverse colon, ascending colon and on occasion may look at the distal part of the small bowel as well.
What is a polyp in the sigmoid colon?
A polyp in the sigmoid colon is an abnormal growth of tissue that forms on the inner lining of the colon, specifically in the sigmoid section, which is the S-shaped part of the large intestine leading to the rectum. Polyps can vary in size and shape, and while many are benign, some have the potential to develop into colorectal cancer over time. Regular screening, such as colonoscopy, is important for early detection and removal of polyps to reduce cancer risk.
What is tethering of sigmoid colon?
Tethering of the sigmoid colon refers to the abnormal fixation or attachment of the sigmoid colon to surrounding structures, which can occur due to inflammation, scarring, or surgical interventions. This condition may restrict the movement of the colon and lead to symptoms such as abdominal pain, constipation, or obstruction. Tethering can complicate surgical procedures and may require intervention if it causes significant discomfort or complications. Diagnosis typically involves imaging studies and clinical evaluation.
Can naproxen sodium be taken before sigmoid colonoscopy?
Sometimes during colonoscopy, biopsies are taken and sent to the lab for testing. Taking tissue samples can result in minor amounts of bleeding, and for this reason, any anti-clotting agent should not be taken in order to avoid hemorrhaging or blood loss. This is why patients are instructed to avoid ibuprofen, aspirin, coumadin, etc.. Unfortunately, naproxen (Aleve) falls into this category and therefore should not be taken up to 7 days prior to colonoscopy as complications may arise with internal bleeding. In addition, naproxen can cause disturbances within the GI tract which could, potentially, interfere with the procedure and results. Best of luck to you with your endoscopy, and I hope this was helpful.

What is the function of sigmoid flexure?
Sigmoid colonThe sigmoid colon is the part of the large intestine after the descending colon and before the rectum. The name sigmoid means S-shaped (see sigmoid). The walls of the sigmoid colon are muscular, and contract to increase the pressure inside the colon, causing the stool to move into the rectum.The sigmoid colon is supplied with blood from several branches (usually between 2 and 6) of the sigmoid arteries, a branch of the IMA. The IMA terminates as the superior rectal artery.
What is proximal sigmoid?
The proximal sigmoid colon is the portion of the large intestine that is closest to the beginning of the sigmoid colon. It is located near the end of the descending colon and functions in absorbing water and electrolytes from the remaining digested food before it moves into the sigmoid colon for further processing.

What is a flexible colonoscopy?
In a colonoscopy, a flexible tube with a lighted mirror at the end is threaded through the anus, rectum, and colon to examine the lower part of the large intestines. The patient receives a short-acting sedative which puts the person in a twilight sleep, so they can respond and move as told to do so, but they will not remember the procedure or any discomfort.
