Constipation is a common clinical syndrome, and the prevalence of constipation among adults in China is about 5%, more in women than in men, and the higher the age, the higher the prevalence. Constipation may be caused by intestinal inflammation, tumors and other diseases, called organic constipation; however, it is more common to see functional constipation without organic intestinal lesions. The symptoms of constipation are decreased frequency of bowel movements, dry and hard stools, and/or difficulty in defecation. According to the Rome III criteria, the diagnosis of constipation should be made by meeting the following criteria for at least the past 6 months: 1. 2 or more of the following must be present: at least 25% of the bowel movements are strained; at least 25% of the bowel movements are dry or hard; at least 25% of the bowel movements are incomplete; at least 25% of the bowel movements have anorectal obstruction and/or blockage; at least 25% of the bowel movements require manual assistance ( At least 25% of the bowel movements require manual assistance (e.g. finger-assisted defecation, pelvic floor support); less than 3 bowel movements per week; 2. Rarely have loose stools without laxatives; 3. Do not meet the diagnostic criteria for IBS. Constipation is often classified clinically as slow-transmission and outlet obstructive. These two types of constipation can be causal and vicious circle, forming a mixed type of constipation. For example, slow-transit constipation leads to dry stools and increased pelvic pressure during defecation, resulting in anatomical abnormalities such as pelvic floor relaxation and rectal prolapse and mucosal overlap, while outlet obstruction prolongs defecation time and exacerbates dry stools and transmission disorders. The treatment of constipation includes lifestyle modification, medical medication and surgical treatment. Lifestyle adjustments include the following: diet: eat more fresh vegetables and fruits, at least 200g of fruits and 400g of tender leafy vegetables (fresh weight) per day; drink a glass of low-fat or nonfat yogurt (100~200g) per day; eat less spicy, dry, hard, and pickled foods; drink water: water contained in food and a small amount of soup during meals, you should also drink at least 1.5~2L of water per day, and if If you sweat a lot in hot weather, you should also increase the amount of water you drink; establish good bowel habits: colon activity is most active in the morning when you wake up and after meals, so it is recommended that patients try to defecate in the morning or within 2 hours after meals, and concentrate on reducing the interference of external factors when defecating. Drugs commonly used for constipation include: intra-volumetric laxatives: mainly various dietary fibers, which can become a component of stool and directly increase stool volume. Osmotic laxatives: such as polyethylene glycol, lactulose, can improve the osmotic pressure to absorb water, increasing the volume of stool. Stimulant laxatives: such as senna, should be used with caution under the guidance of a doctor; enemas and suppositories: such as glycerin enemas, can stimulate the intestinal wall to soften stool and facilitate its elimination. Since the sigmoid colon is on the left side of the body, lying on the left side may help enemas flow deeper. A small percentage of patients with constipation cannot be effectively relieved despite regular medical treatment, or the constipation gradually worsens over time and eventually requires surgical treatment. Surgical treatment of constipation is a risky and invasive treatment, and the indications for surgery should be met: meeting the Rome III diagnostic criteria; the condition persists for more than 4 years; regular and strict medical treatment is ineffective; the patient’s quality of life is seriously affected; and the organic disease causing constipation is excluded. In layman’s terms, this means “nothing to do, no pain”: if there are drugs or methods that have not been tried in internal medicine, there is no hurry to operate, but to try these drugs or methods first; if the patient feels that the constipation is still tolerable, there is no hurry to operate, and only when it is unbearable can we consider surgery. The use of colectomy for constipation was reported nearly a century ago, but the early procedures were not ideal for improving quality of life due to complications and effectiveness. The Jinling procedure is a modified subtotal colectomy designed by the Southern Military General Hospital, which removes most of the colon from the hepatic flexure to the junction of the rectum and removes the appendix at the same time (because the position of the appendix changes dramatically after surgery, which makes it difficult to diagnose and treat appendicitis once it occurs); after freeing the posterior wall of the rectum, the ascending colon is laterally anastomosed with the rectum. The subtotal resection of the colon removes the redundant and dynamically impaired bowel segment, and the anastomosis of the posterior wall of the rectum relieves the anatomical abnormalities around the rectum, and the lateral anastomosis can obtain a large and open anastomosis, so this procedure can solve the problems of slow transmission and exit obstruction at the same time. At the same time, this procedure preserves the ileocecal portion and part of the ascending colon to prevent severe postoperative diarrhea; and fully protects the pressure-sensing function of the anterior rectal wall to preserve the postoperative bowel control ability.
