How to treat rectal prolapse?
Rectal prolapse mainly includes external rectal mucosal prolapse and internal rectal mucosal prolapse. External rectal mucosal prolapse primarily refers to the symptoms and types of clinical rectal prolapse. The most common and effective treatment for rectal prolapse or internal rectal mucosal prolapse is surgery. Simple medication can only relieve local relaxation or compressive symptoms, but it does not have a definitive therapeutic effect on the disease itself. The surgery mainly involves the removal and excision of the relaxed and prolapsed mucosa, thereby increasing the tightness of the intestinal mucosa and relieving the local mucosal pressure on the anus, which causes the patient's feelings of bloating and descent. After the surgery, patients need to rest in bed for a week and should avoid squatting and excessive abdominal straining in their future activities.
Why is a perianal abscess so painful?
During the acute phase of a perianal abscess, the intense pain is mainly due to the formation of an abscess and pus pockets in the subcutaneous area around the anus. The pus within these cavities cannot rupture, causing localized skin nerves to experience pecking-like or jumping pain. The pain from a perianal abscess is generally unbearable for patients, necessitating prompt surgical treatment. The surgical approach for a perianal abscess primarily involves incision and drainage, followed by debridement of the abscess cavity. It is important to note that postoperative disinfection and dressing changes of the local wound are crucial to prevent false healing of the wound.
What should be paid attention to for anal fistula?
Patients with anal fistula, as there is an external opening in the anal region and intermittent thick secretion from this opening, should first ensure to keep the perianal area clean. It is recommended to change underwear daily and to cleanse the area after bowel movements with saline or hemorrhoid wash, and to conduct fumigation and hot compresses around the perianal area and the external opening to prevent irritation and even sharp pain caused by residual feces and secretions. Furthermore, during acute episodes of anal fistula, mupirocin ointment can be applied around the external opening for anti-inflammatory treatment. The definitive surgery for anal fistula primarily involves fistulotomy with seton placement. Without surgery, an anal fistula cannot be completely cured and may lead to worsened conditions such as thickening of the fistula wall or increased branching of the fistula channels.
How many days is the hospital stay for perianal abscess surgery?
After surgery for a perianal abscess, due to the presence of a local wound and the significant discharge from the wound in the early postoperative period, combined with the potential fall of ligatures or elastic bands at the area, a hospital stay of approximately two weeks is required. For severe cases or those with deeper abscess cavities, a hospital stay of three weeks or even a month might be necessary. The main purpose of the hospital stay post-surgery is to monitor for any major bleeding from the wound, and to facilitate dressing changes. Postoperative dressing changes for a perianal abscess wound are crucial for recovery, as only thorough daily disinfection and dressing changes can ensure uniform granulation and growth of local tissues, prevent the enclosure of pus within the local cavity leading to pseudohealing or reinfection, and thus affect the treatment outcome of the surgery. Approximately one month after surgery, regular follow-up visits are required to monitor the healing of the local wound.
How to deal with a ruptured anal fistula?
The clinical symptoms of anal fistula mainly include intermittent discharge of pus from the external opening near the anus, or occasional acute attacks that cause redness, swelling, heat, and pain around the external opening of the anus. If the external opening of the anal fistula breaks and discharges pus, or is accompanied by pain, it is considered an acute phase of the anal fistula. The primary method of management and treatment is surgery, with the main surgical approach being fistulotomy and seton placement. To locally alleviate the inflammatory symptoms of the external opening of the anal fistula, anti-inflammatory ointments can be applied for temporary anti-inflammatory treatment. However, to avoid the local complications such as thickening or branching of the fistula, it is advised that patients undergo surgical treatment of the anal fistula as soon as possible. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
Perianal abscess clinical manifestations
Perianal abscess is an acute infectious disease of the local skin, mucosa, and sphincter around the anus, characterized by certain acute clinical symptoms, most commonly pain. The onset of a perianal abscess is generally sudden, occurring within one to three days. Due to the formation of a local pus cavity, intense pain is experienced along with the red, swollen, and hot skin in the affected area. The nature of the pain is often throbbing or pecking. If the infection worsens or is not actively treated, it may also cause systemic symptoms such as fever and chills due to the pain and infection. With repeated attacks over a long term, or if the patient's physical condition is poor, further symptoms like fatigue might occur. Acute episodes of perianal abscess require prompt surgical intervention.
Does an anal fistula hurt?
Anal fistula mainly refers to the presence of a noticeable fistula in the tissue under the perianal skin, which connects the inner opening in the anal canal and the outer opening around the anus. Usually, the anal fistula does not cause significant pain when it is not in acute flare-up. However, if the anal fistula enters an acute episode, there may be pain due to inflammation at the local external opening of the anus, and possibly an increase in purulent discharge, which can irritate the skin around the external opening, causing stinging pain and itching. To prevent recurrent episodes of anal fistula and further aggravation of the condition, it is advised to seek surgery as soon as the fistula is detected.
Is anal fistula prone to recurrence?
If active anal fistulotomy and thread-drawing surgery are carried out after the onset of an anal fistula, it generally does not recur easily. However, if patients do not pay attention to good dietary and defecation habits after being discharged, it may lead to the reoccurrence of the anal fistula. This is because there are multiple anal crypts within the anal canal, and removing the local anal crypts during this episode does not guarantee that other anal crypts will not become inflamed or infected in the future. Especially when patients consume excessive amounts of chili peppers or alcohol, or when they experience diarrhea, it can potentially trigger another infection of the anal crypts. Therefore, to prevent recurrence of anal fistulas, it is necessary to cultivate good defecation and dietary habits to avoid the reoccurrence of anal fistulas.
Can an anal abscess be left untreated without surgery?
Surgical treatment is required during the acute phase of a perianal abscess. If surgery is not performed, it could lead to an expansion of the abscess cavity or worsening of the infection. Severe cases may lead to a local cellulitis around the anus, forming an inflammation of the cellular tissue. The surgical approach for a perianal abscess primarily involves incision and drainage, complemented by a one-time radical cure. The surgical principle mainly involves excising the infected local lesions altogether, thoroughly disinfecting and dressing the area, accelerating the shedding of the local infection, and ensuring normal growth of granulation tissue. Postoperative dressing changes are also crucial for the recovery from a perianal abscess.
How long does it take to recover after surgery for an anal fistula?
After surgery for an anal fistula, the general recovery time is about twenty days to a month. The duration of recovery mainly depends on the size of the local lesion before surgery, as well as the surgical wound postoperatively, and also relates to the patient's constitution. Particularly, if the patient has certain underlying diseases, such as diabetes or a history of tuberculosis, the recovery time may be relatively extended. The wound after an anal fistula surgery is an open wound contaminated with bacteria, so postoperative wound dressing changes are very important for wound recovery. It is recommended that the secretion from the local wound be cleared daily, followed by disinfection with povidone-iodine, then application of an anti-inflammatory ointment, and covering the wound with an oil gauze strip for drainage to avoid poor drainage leading to false healing of the local wound.
