Colonic fecal lithotripsy is an obstructive lesion caused by a calcified fecal mass remaining in the rectum or in the intestinal canal above the rectum that causes fecal inaccessibility and intestinal obstruction. It can occur in any part of the intestinal tract, commonly in the rectum, followed by the sigmoid colon and cecum. It is mostly seen in patients with poor defecation, dry stools and elderly people with low activity and reduced intestinal motor function. (a) Diagnostic points: 1. Patients with symptoms mostly have a history of poor defecation, constipation, inability to smoothly pass stool, accompanied by diarrhea-like stool, abdominal distension, abdominal pain, or a sense of urgency. 2.Signs: hard swelling can be palpated in the abdomen and move with the intestinal canal; rectal end can be palpated or intestinal fecal mass can be seen by anal palpation or sigmoidoscopy; intestinal cavity is swollen and thickened by fecal mass. 3, auxiliary examination abdominal plain film can be found in the rectum, sigmoid colon or cecum area round walnut to apple, or even larger uneven density shadows, mostly single, sometimes multiple melon-shaped shadow. There are often irregular circular circles of calcification at their outer edges, and regular calcifications are seen inside as patchy translucent areas. During barium enema, the barium often reaches the fecal mass and is obstructed. Fecal stone masses can move slightly in the intestinal lumen without a tip, and there is no infiltration and hardening of the surrounding intestinal wall. (B) clinical typing 1, true fecal stone whose core consists of epithelium of intestinal mucosa, small fecal stones, nuclei, but also other foreign bodies in the intestinal cavity as the core, by calcium, phosphorus, magnesium and other alkaline salts deposited to form fecal stones, mostly in the rectum, obviously affect defecation. 2, mixed fecal stone that is plant gross fecal stone, is also a kind of shell or bran as the core, the alkaline contents of the intestine deposited outside and formed by the fecal stone, often occurring in the cecum and ileum end. 3, drug fecal stone due to long-term oral intake of calcium, magnesium, bismuth compounds formed in the intestine of the fecal stone. Also reported in the intestine of painters or artificial paint mechanics, can form fecal stones composed of paint. (C) Treatment principles Removal of fecal stones from the intestine, unblocking the intestine, improving the bowel function and preventing the reoccurrence of fecal stones are the main reasons. 1.Removal of intestinal fecal stones Drug or lubricating fluid For smaller fecal stone disease, the patient can be allowed to take laxative drugs and intestinal dynamics drugs orally, with the help of drugs, fecal stones are excreted with the stool; you can also use soap solution or lubricating fluid enema to reach the purpose of removing fecal stones and unblocking the intestinal tract. 2.Local excretion of fecal stone method for large, hard texture of the fecal stone, in the drug and enema can not be discharged fecal stone disease, such cases need to use the finger first anal or rectal fecal stone hollowing, hook out of the anus, while also available catheter to the rectum injection of liquid paraffin, so that the patient transformed outside the body, so that the intestinal wall fully lubricated, but also in the perianal local anesthesia or sacral anesthesia, so that the sphincter muscle fully relaxed, and then use the oval forceps to remove the fecal stone from the The fecal stone can be removed from the anus or intestine with oval forceps. This treatment method is common in clinical practice for anal fecal stone disease and rectal fecal stone disease, and the treatment effect is better and the patient suffers less pain. 3.Surgical treatment For fecal stones above the rectum, such as fecal stones from the cecum to the sigmoid colon, if conservative treatment is not effective, it is feasible to remove the stones by intestinal wall incision, which is less common. Everyone has various habits, and stool is no exception, to a certain time to defecate, if often delayed stool time, destroy the good defecation habits, can make the defecation reflex weak, cause constipation, so do not artificially control the sense of defecation. For those who are often prone to constipation must pay attention to the bowel arrangement in a reasonable time, every time to go to the toilet, to develop a good defecation habits. 4, active physical exercise: activities, activities, stool since the passage. Walking, running, deep breathing exercises, qigong, taijiquan, turn the waist and lift the legs, participate in cultural and sports activities and physical labor, etc. can make the gastrointestinal activities to strengthen, appetite, diaphragm, abdominal muscles, anal muscles to exercise; improve defecation power, prevent constipation. Regular labor of rural elderly rarely constipation, and lazy activities, the urban elderly constipated more, which explains this reason. 5, timely treatment of relevant diseases: the treatment of relevant diseases on the prevention of constipation also has a certain role. Such as allergic colitis, colonic diverticulitis, colon tumors, colon stenosis; hypothyroidism diabetes; uterine fibroids; lead, mercury and other metal poisoning. As long as the prevention and prevention of constipation, the occurrence of fecal lithotripsy will disappear with it, to do the above, you can well treat and prevent fecal lithotripsy.
