A meatball in the anus without pain is usually caused by hemorrhoids, but very few patients may also be due to other diseases, such as rectal polyps, rectal prolapse, anal cancer, etc. Such patients need to go to the hospital’s anorectal department in a timely manner, to clarify the cause and then carry out the relevant treatment. The actual hemorrhoids can be found in the anal cushion structure and the surrounding venous plexus, which can cause congestion, hyperplasia, hypertrophy and displacement of the anal cushion, which can be dislodged from the anus during defecation, standing, coughing, exertion and weight bearing, and then a meatball can appear at the anus. Initially, internal hemorrhoids can retract on their own, gradually progressing to retracting by hand, and in severe cases, it is difficult to retract after the hemorrhoid has prolapsed. Internal hemorrhoids are mainly treated with medication, including topical creams and suppositories; in addition, patients should adjust their diet and improve their lifestyle, such as avoiding spicy and irritating foods and being sedentary. 2. External hemorrhoids: For patients with external hemorrhoids, there may be pathological expansion of blood microcirculation such as venous plexus or proliferation of connective tissue under the skin on the distal side of the dentate line to form anal hemorrhoid masses, which can be accompanied by itching. Generally, asymptomatic external hemorrhoids do not need treatment, usually increase the intake of fibrous food and change bad bowel habits; if pain, bleeding and other uncomfortable symptoms occur, you can go to the hospital and have them removed surgically; 3. Mixed hemorrhoids: they are hemorrhoids formed by the fusion of internal hemorrhoids with their associated external hemorrhoids through the anastomosing branches of the perianal plexus, and when the tissue around the hemorrhoid is destroyed and atrophied, the hemorrhoid nucleus gradually When the tissue around the hemorrhoid is destroyed and atrophied, the hemorrhoid nucleus gradually enlarges, moves down and separates from the muscle layer and comes out of the anus, then a meatball may appear in the perianal area. The initial stage of mixed hemorrhoids can be treated with non-steroidal anti-inflammatory drugs, such as acetaminophen and diclofenac sodium, under the guidance of a doctor. If the symptoms are not relieved for a long time after conservative treatment, you should immediately go to the hospital for surgical treatment, such as external peeling and internal ligation, mucosal circumferential anastomosis, etc. Second, other diseases 1, rectal polyps: mainly due to the abnormal proliferation of some cells in the rectum, resulting in redundant rectal mucosa, when these redundant with the stool out, can appear around the anus meatballs, and no pain. For small size meatballs can be treated by anal resection, for larger size meatballs can be treated by endoscopic trap removal; 2. Rectal prolapse: mainly due to weak pelvic floor tissues, increased abdominal pressure and other factors leading to prolapse of anal masses, which then manifests as meatballs around the anus. The patient may be asked to elevate the buttocks in a prone position, and the doctor will apply quartz oil and other lubricants and gently massage around the anus, using force evenly from the tip of the prolapsed intestine to the anus, until the prolapsed rectum is returned. Anal cancer is a relatively rare malignant tumor clinically, which is caused by long-term stimulation and damage from various factors, resulting in degenerative cell changes and loss of the ability to re-differentiate normally, leading to cancer and the appearance of meatballs in the anus. For early stage anal cancer, itching may occur, but the pain is usually mild or not obvious. For such patients, it is recommended to go to hospital for proctoscopic examination in time to clarify the type and stage of tumor and carry out relevant treatment, which usually adopts chemotherapy and radiotherapy, mainly mitomycin and capecitabine given simultaneously with radiotherapy, and for some patients, local excision through surgery may also be required.
