How does vesical colonic fistula check?

summary

Vesicocolonic fistula is a common colonic fistula disease in daily life. Special attention should also be paid to diet. Due to the connection between bladder and colon, urinary system is vulnerable to infection, which brings great harm to patients. So, let's take a look at how to check for vesicocolonic fistula? Let's introduce the related knowledge of the field.

How does vesical colonic fistula check?

First, colonoscopy can find the abnormal opening of gastrointestinal tract and make differential diagnosis. When duodenoscopy entered duodenum, the mucosa was soft and smooth, and the nipple was located on the longitudinal uplifted plica in the medial descending segment of duodenum. Generally, the fistula was located above the opening of nipple, and the shape was irregular star shape, without normal nipple shape and opening characteristics. When the fistula is covered by mucous membrane, it is not easy to find, but intubate from the nipple opening, the catheter can be turned back to the intestinal cavity from the fistula, and intubate from the fistula above the nipple. The abnormal channel is developed and diagnosed. At this time, observe the mirror close to the fistula, and bile or other liquid can be seen overflowing. Endoscopic duodenal fistula should be distinguished from duodenal diverticulum. Diverticulum can also have an opening near the duodenal papilla, but the edge is more regular, the opening is mostly round, and there are often food residues in the cavity. After removing the residues, the catheter at the bottom of the diverticulum can be seen to insert into the cavity, that is, it can be folded back into the intestinal cavity to inject contrast agent, which can all overflow. At the same time, contrast agent can be seen in the intestinal tract, The other group reported 47 cases of choledochoduodenal fistula combined with duodenal diverticulum, 5 cases had papilla and fistula located in the cavity of the large diverticulum. Barium examination was taken immediately after endoscopy, which confirmed that the large diverticulum in the medial descending segment of duodenum could be clearly located by fiber colonoscopy, and the size of the fistula could be observed, Or tissue examination to determine the nature of the primary lesion to provide the basis for the choice of surgical methods.

Second, laparoscopy can also be used as a means of diagnosis and treatment of duodenal fistula, and has a wide application prospect. Cystoscopy: when duodenal (ureteral) fistula is suspected, in addition to cystitis signs, air bubbles or purulent debris can be seen at the ureteral opening on the affected side; Or after the contrast agent was injected through the catheter of the ureter on the diseased side, the contrast agent could be found in the duodenum. At present, the diagnosis mainly depends on retrograde pyelography, nearly 2 / 3 of the patients are positive.

Third: bone charcoal powder test: after oral administration of bone charcoal powder, black charcoal particles were excreted from urine 15-40 minutes later. This examination can only confirm the existence of internal fistula between digestive tract and urinary tract, but can not determine the location of fistula.

matters needing attention

Vesicocolonic fistula does great harm to human body. Feces in the colon often enter the bladder through the fistula, causing urinary tract infection. The treatment of this disease needs surgery to cure, at the same time, pay attention to diet conditioning in diet, can effectively alleviate.
