transverse colon ptosis
Introduction
Introduction The length of the transverse colon is the splenic syndrome that used to be said. Because the transverse colon is too long, some sag to the pelvic cavity, and the liver and spleen are relatively fixed. It forms an acute angle in the liver and spleen, and the discharge resistance increases, and the stool stays for a long time. In patients with constipation, the transverse colon can gradually lose its function. The occurrence of this disease is mostly due to insufficient suspension force of the diaphragm, liver and stomach, ligament ligament dysfunction and relaxation, abdominal pressure drop and abdominal muscle relaxation and other factors, plus body shape or physical factors and other factors, so that the stomach is extremely bottom The low-profile fish structure is the tension-free stomach seen by the stomach.
Cause
Cause
Sagging of the stomach causes the transverse colon to sag. The occurrence of this disease is mostly due to insufficient suspension force of the diaphragm, liver and stomach, ligament ligament dysfunction and relaxation, abdominal pressure drop and abdominal muscle relaxation and other factors, plus body shape or physical factors and other factors, so that the stomach is extremely bottom The low-profile fish structure is the tension-free stomach seen by the stomach.
Examine
an examination
Mild sagging of the stomach, generally asymptomatic, ptosis is obvious, there is upper abdominal discomfort, fullness, obvious after meals, accompanied by nausea, belching, anorexia, constipation and so on. Sometimes the abdomen has a deep pain, often after the meal, standing and tired after aggravation, long-term gastric ptosis often have weight loss, fatigue, standing fainting, low blood pressure, palpitations, insomnia, headache and other symptoms.
Diagnosis
Differential diagnosis
Transverse colonic displacement: Pancreatic cysts include true cysts, pseudocysts, and cystic tumors. True cysts include congenital simple cysts, polycystic disease, dermoid cysts, and retention cysts. The inner wall of the cyst is covered with epithelium. Cystic tumors include cystic adenomas and cystic carcinomas. The wall of the pseudocyst is composed of fibrous tissue and is not covered with epithelial tissue. Clinically, pancreatic cysts are most common with pseudocysts. X-ray barium meal examination also has a localization value for pancreatic pseudocysts. In addition to excluding the lesions in the gastrointestinal cavity, the signs of compression and displacement of the cysts on the surrounding organs can be seen. If there is a large pseudocyst in the stomach, the tincture can show that the stomach is moving forward, and the stomach can be compressed. A pseudocyst in the head of the pancreas can widen the duodenal curvature and shift the transverse colon upward or downward.
Colonic obstruction: Colonic obstruction can occur anywhere in the colon, but in the left colon. Cancerous obstruction often has typical chronic colonic obstruction, such as constipation, diarrhea, pus and bloody stool, bowel habits and shape changes, abdominal pain in the right colonic obstruction in the right and middle abdomen, left abdominal obstruction and abdominal pain in the left lower abdomen . Chronic obstruction can develop gradually or suddenly into acute obstruction. Beal suggested that progressive bloating and constipation in the elderly are typical colon cancer obstructions. Normal people have 10% to 20% ileocecal valve insufficiency, part of the colon content can return to the intestine to cause small intestine dilatation, gas accumulation, fluid, easily misdiagnosed as low intestinal obstruction. If the ileocecal valve function is good, a closed bowel segment is formed between the ileocecal part and the obstruction part; at this time, the gas and liquid in the ileum continuously enter the colon, causing the colon to swell, the abdominal distension is obvious, and the exhaust and defecation are completely stopped, but still No vomiting. In addition to abdominal distension during the examination, intestinal type or sputum and lump can be seen, and digital rectal examination and X-ray examination should be performed. In the abdominal fluoroscopy or abdominal plain film, the proximal intestinal fistula showed obvious expansion, and the distal intestinal fistula showed no gas. The standing position showed fluid level in the colon. Barium enema helps to identify, and at the same time it can play an important role in establishing the site of obstruction and the cause. Buechter reported a diagnosis rate of 97% and 94% for abdominal X-ray and barium enema, respectively.
Colonic swelling: ulcerative colitis (UC), referred to as ulceration, unexplained rectal or colonic inflammatory disease. Mainly involving the rectum, sigmoid colon and descending colon, pathological features of mucosal congestion, edema, multiple superficial ulcers, advanced intestinal wall thickening, intestinal stenosis and associated with polyps. Clinically, it is characterized by intractable diarrhea, mucus, bloody stool or pus and bloody stool, abdominal pain and urgency. It can be accompanied by parenteral manifestations such as fever, anemia, arthritis, skin lesions and liver disease. Very few acute onset, most of the onset is slow, the course of disease is longer, often recurrent, and the period of reversal is also called chronic non-specific ulcerative colitis. Abdominal pain, diarrhea, and bloody stools can occur early. Different degrees of abdominal pain are caused by colonic muscle spasm, colonic swelling and inflammation stimulating local sensory nerves. Abdominal distension is mostly confined to the left lower abdomen or lower abdomen, showing paroxysmal mild pain. Colic can be present when the lesion is severe.
