intersigmoid hernia

Introduction

Introduction to sigmoid colon The intestine is caused by the sigmoid colon between the root of the sigmoid mesenteric and the posterior peritoneum, which is called intersigmoid hernia. More rare. Epidemiology: There is currently no relevant content to describe the cause: the cause of sigmoid colon sputum is unclear. It is generally believed that the presence of sigmoid crypt is the anatomical basis of its pathogenesis. The intersigmoid recess is a gap formed by the sigmoid mesentery not fully fused with the posterior peritoneal wall. Located on the left side of the sigmoid mesenteric root, just in the shape of a sigmoid colon, it is attached to the top of the posterior wall of the abdomen and has an upward funnel-shaped crypt, with the mouth facing to the left. The size of the fossa is from a small concave to a small fingertip. The anterior edge of the crypt is the sigmoid colonic blood vessel, the superficial sigmoid mesenteric membrane, the deep common iliac artery, and the left ureter of the vein just at the bifurcation of the common iliac artery. About 2/3 (60.52%) of the individuals in the normal population have the most common crypt, especially in the fetus and infancy, and may gradually disappear with age. basic knowledge Sickness ratio: 0.001%-0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: intestinal obstruction shock

Cause

Cause of sigmoid colon

Cause:

The cause of sigmoid colon sputum is unclear. It is generally believed that the presence of sigmoid crypt is the anatomical basis of its pathogenesis.

The intersigmoid recess is a gap formed by the sigmoid mesenteric membrane that is not fully fused with the posterior peritoneal wall. It is located on the left side of the sigmoid mesenteric root, just in the shape of a sigmoid colon, attached to the posterior wall of the abdomen. At the top, there is an upward funnel-shaped crypt with the mouth facing to the left.

About 2/3 (60.52%) of the individuals in the normal population have this crypt, especially in the fetus and infancy, and may gradually disappear with age.

Prevention

Sigmoid colon fistula prevention

Avoid lifting, pushing, or pulling heavy things; give up or try to smoke less, smokers' cough may accelerate the development or worsening of suffocation, give up smoking to improve blood, speed up the recovery process; eat less easily cause constipation and intra-abdominal Flatulent foods (especially cooked eggs, sweet potatoes, peanuts, beans, beer, carbonated sparkling drinks, etc.), eat high-fiber diets, including grains, grains, bran, and unprocessed fruits and vegetables; drink at least every day Eight glasses of water can help relieve constipation; avoid and reduce sneezing; deep breathing can help alleviate chronic cough.

Complication

Sigmoid colon fistula complications Complications, intestinal obstruction, shock

Intestinal obstruction, which is a common acute abdomen, can be caused by a variety of factors. At the beginning of the disease, the intestinal segment of the obstruction has anatomical and functional changes first, followed by the loss of fluid and electrolyte, intestinal circulatory disturbance, necrosis and secondary infection. Finally, it can cause toxemia, shock, and death.

Symptom

Symptoms of sigmoid colon sputum common symptoms intestinal sputum abdominal distension abdominal pain lower abdominal pain nausea left lower abdomen can be touched...

Recurrent paroxysmal left lower abdominal pain, accompanied by post-meal nausea, vomiting and bloating, if complete intestinal obstruction occurs, abdominal pain is aggravated, from paroxysmal to persistent, and exhaust defecation stops, physical examination: left lower abdomen It can touch the tenderness mass and smell the bowel sounds.

Although there are many sigmoid crypts in many people, it is extremely rare to have sigmoid colon in the clinic. Clemenz and Kemmerer (1967) reported in a comprehensive literature that only 34 cases were found in the literature. No specific symptoms, preoperative diagnosis is very difficult, often in the surgical exploration found that an enlarged small intestinal fistula into the sigmoid crypt can be diagnosed, if there are the following, after exclusion of other diseases, consider the sigmoid colon Between.

Examine

Examination of sigmoid colon

X-ray examination

(1) Abdominal fluoroscopy or plain film: visible small left intestine on the left or right side, dilated gas or fluid in the intestine, and other signs of intestinal obstruction.

(2) gastrointestinal sputum angiography: helpful for the diagnosis of sigmoid sputum, only suitable for patients with signs of intestinal obstruction. Typical image:

1 agglomerate small intestine spasm is concentrated on the left or right side of the abdomen, the intestine is not easy to separate, pushing or changing the patient's position by hand, the small intestine mass does not move, like the bag.

2 sputum in the small intestine through the slow; small pelvis in the pelvic cavity, the position of the terminal ileum is normal, colon and stomach position often change. A characteristic image of the sigmoid colon: the small intestine gathers into a mass (squat), located in the right abdomen. When the patient is erect, the stomach often sag to the left side of the small intestine mass (the mass), the descending colon is on the left side, and the ascending colon can be Its right side, rear, front or side to the left front side.

Diagnosis

Diagnosis and differentiation of sigmoid colon

1. Complete or incomplete intestinal obstruction; paroxysmal left lower abdomen pain; left lower abdomen can touch tender mass, and bowel sound hyperthyroidism is its main sign.

2. X-ray examination showed signs of intestinal obstruction.
