Basic information] Male, 17 years old [Disease type] Intractable constipation [Hospital] No.988 Hospital of PLA Joint Logistics Force [Consultation time] May 2022 [Treatment plan] Abscess incision, debridement and drainage + enema + medication (Lactulose oral solution) + dietary adjustments [Treatment cycle] 1 week of hospitalization, out-of-hospital follow up for 2 months [Effect of the treatment] Constipation and fissure have significantly improved, and pain relief in defecation. A 17-year-old student came to our clinic, saying that he had stomach distension, pain in the buttocks with bleeding, frequent hiccups, and had not had a bowel movement for several days, which prevented him from concentrating on his studies and caused a significant drop in his grades, and that he was very anxious because he was about to face the college entrance examination. After further communication with the patient, it was found that the patient usually had small boils on his back and buttocks, but he would often pick and squeeze them by himself. Further examination of the patient revealed that the boils on his buttocks were infected after picking and squeezing, and small abscesses formed on the wounds, which led to pain when he tried hard, fear of defecation, and constipation caused by prolonged absence of defecation, which was accompanied by anal fissure, making it even more difficult to relieve the bowel movement. After consultation with the Department of Anus and Intestines, the patient was diagnosed with persistent constipation, which required debridement and drainage, as well as enema treatment. As the constipation was stubborn, the patient and his family agreed to be hospitalized. After the patient was admitted to the hospital, the abscess in his buttocks was first incised and drained, and after the operation, the pain in the infected buttocks was relieved, and the pain was reduced when he squatted, and the patient was able to exert himself appropriately when he had a bowel movement. At the same time, the patient was treated with laxative and laxative therapy, and two enemas were administered two times in the first two days before admission to relieve the pain of persistent constipation. On the third day, the patient was given lactulose oral solution, and the patient was asked to increase vegetables, fruits and dietary fiber-rich foods in the diet, so as to make her stools gradually smooth. After active treatment, the patient’s buttock incision began to heal. As the patient was treated with 2 enemas, he could defecate in the toilet by himself on the 3rd day. At the same time, because lactulose oral solution can effectively laxative, so after a period of 5 days of drug treatment, the patient’s stubborn constipation has been significantly improved, the stool can reach the standard of once a day, stool molding, softer, anal fissure situation improved significantly, defecation is no longer bleeding, defecation pain is reduced. Considering the patient’s tight study schedule and good recovery, the patient was allowed to be discharged from the hospital for recuperation after 1 week of hospitalization. The patient was asked to follow up for 2 months after discharge. After a series of treatments, the patient’s persistent constipation and anal fissure were improved, and the attending physician was very happy. However, since the patient was not completely cured when he was discharged from the hospital, he still needs to pay attention to the following situations in his daily life: 1. Keep a light diet in his daily life, drink more noodle soup and rice porridge, increase the intake of vegetables, fruits and fiber-rich foods, avoid spicy and oily foods, and do not smoke or drink alcohol; 2. 3, due to the patient’s current study tension, often late at night, easy to anxiety and lead to diarrhea or constipation, so if you usually have abdominal discomfort, stool abnormalities, you can take a small amount of oral lactulose oral solution to relieve the symptoms, and if necessary, go to the hospital in time for treatment. V. Personal perception In daily life, constipation is very common, there are functional causes, there are organic diseases, there are lesions of the intestine itself, but also may be due to other factors, such as hemorrhoids, anal fissure, intestinal tumors, neuromyelitis optica, diabetic intestinal paraparesis and so on. In this case, the patient was suffering from chronic stress and sedentary lifestyle, which led to the inability to pass stools, coupled with the infection of boils on the buttocks, which prevented him from straining to pass stools and led to the formation of persistent constipation, affecting his studies and life. Therefore, in the face of boils on the skin, do not pick and squeeze, if repeated constipation discomfort, should go to the hospital in a timely manner to clarify the diagnosis. If it is functional constipation, you can adjust the work and rest, diet structure, but also with abdominal massage, acupuncture, moxibustion, exercise and other methods to regulate.
