Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up.

Review
When created properly, an ileostomy or colostomy can dramatically improve a patient's quality of life. Conversely, when a patient develops complications related to their stoma, the impact on physical and mental health can be profound. Unfortunately, significant morbidity is associated with stoma creation conveying high rates of both early and late-term complications. Early complications include stomal ischemia/necrosis, retraction, mucocutaneous separation, and parastomal abscess. Late complications include parastomal hernia, prolapse, retraction, and varices. This review will discuss commonly occurring nondermatological stoma complications and detail management strategies for the ostomate and the surgeon.

Review
Common anorectal conditions include hemorrhoids, perianal pruritus, anal fissures, functional rectal pain, perianal abscess, condyloma, rectal prolapse, and fecal incontinence. Although these are benign conditions, symptoms can be similar to those of cancer, so malignancy should be considered in the differential diagnosis. History and examination, including anoscopy, are usually sufficient for diagnosing these conditions, although additional testing is needed in some situations. The primary treatment for hemorrhoids is fiber supplementation. Patients who do not improve and those with large high-grade hemorrhoids should be referred for surgery. Acutely thrombosed external hemorrhoids should be excised. Perianal pruritus should be treated with hygienic measures, barrier emollients, and low-dose topical corticosteroids. Capsaicin cream and tacrolimus ointment are effective for recalcitrant cases. Treatment of acute anal fissures with pain and bleeding involves adequate fluid and fiber intake. Chronic anal fissures should be treated with topical nitrates or calcium channel blockers, with surgery for patients who do not respond to medical management. Patients with functional rectal pain should be treated with warm baths, fiber supplementation, and biofeedback. Patients with superficial perianal abscesses not involving the sphincter should undergo office-based drainage; patients with more extensive abscesses or possible fistulas should be referred for surgery. Condylomata can be managed with topical medicines, excision, or destruction. Patients with rectal prolapse should be referred for surgical evaluation. Biofeedback is a first-line treatment for fecal incontinence, but antidiarrheal agents are useful if diarrhea is involved, and fiber and laxatives may be used if impaction is present. Colostomy can help improve quality of life for patients with severe fecal incontinence.

Review
Ileostomy or colostomy formation is an important component of many surgical procedures performed for a wide range of disorders of the gastrointestinal tract. Despite the frequency with which intestinal stomas are created, stoma-related complications remain common and are associated with significant morbidity as well as cost. Some of the most prevalent complications of stoma formation which will be detailed in this article include peristomal skin complications, retraction, stomal necrosis, stomal stenosis, prolapse, bleeding, dehydration from high ostomy output, and parastomal hernia. The authors will review these common complications, detail means to avoid or prevent them, and outline recommendations for management.

Review
Rectal prolapse is a debilitating condition that often results in impaired quality of life. Posterior compartment defects including rectal prolapse and rectal intussusception are often associated with middle and anterior compartment prolapse and require a multicompartment approach to treatment. In recent years, ventral rectopexy, with or without sacrocolpopexy for combined middle compartment prolapse, has emerged as a safe and effective method of treatment for rectal prolapse. In this article, we aim to review the etiology of rectal prolapse and intussusception, describe the indications and workup for surgery, discuss technical aspects of ventral rectopexy alone and in combination with sacrocolpopexy, review potential surgical complications, and describe the reported outcomes of the surgery.

Review
Cystic fibrosis is one of the most common inheritable traits in Caucasians. Meconium ileus and its potential complications are the most likely reasons that these patients will need surgical care. Surgical intervention is usually needed in the neonatal period but may also be required later in life. This article discusses the various ways cystic fibrosis can affect the gastrointestinal tract. Both the operative and nonoperative management of complicated and uncomplicated meconium ileus are discussed in the neonatal period as well as long-term issues, such as distal intestinal obstructive syndrome, fibrosing colonopathy, and rectal prolapse, all of which may be seen in older children and adults.

Review
Rectal prolapse is a common and self-limiting condition in infancy and early childhood. Most cases respond to conservative management. Patients younger than 4 years with an associated condition have a better prognosis. Patients older than 4 years require surgery more often than younger children. Multiple operative and procedural approaches to rectal prolapse exist with variable recurrence rates and without a clearly superior operation. These include sclerotherapy, Thiersch's anal cerclage, Ekehorn's rectopexy, laparoscopic suture rectopexy, and posterior sagittal rectopexy.

BACKGROUND
Pyroptosis is a form of proinflammatory gasdermin-mediated programmed cell death. Abnormal mucosal inflammation in the intestine is a critical risk factor for colitis-associated colorectal cancer (CAC). However, it is unknown whether pyroptosis participates in the development of CAC.
METHODS
To investigate the role of gasdermin E (GSDME)-mediated pyroptosis in the development of CAC, Gsdme mice and their wild-type (WT) littermate controls were challenged with azoxymethane (AOM) and dextran sodium sulfate (DSS) to induce a CAC model. Neutralizing antibodies against high-mobility group box protein 1 (HMGB1) were used to determine the role of HMGB1 in CAC. To identify the role of ERK1/2 in HMGB1-induced colon cancer cell proliferation, we performed western blotting and CCK8 assays using the ERK1/2-specific inhibitor U0126 in CT26 colon cancer cells.
RESULTS
In the CAC model, Gsdme mice exhibited reduced weight loss and colon shortening, attenuated rectal prolapse, and reduced tumor numbers and sizes compared to WT littermates. Furthermore, treatment with neutralizing anti-HMGB1 antibodies decreased the numbers and sizes of tumors, ERK1/2 activation and proliferating cell nuclear antigen (PCNA) expression in AOM/DSS-challenged WT mice. In addition, our in vitro experiments demonstrated that HMGB1 induced proliferation and PCNA expression in CT26 colon cancer cells through the ERK1/2 pathway.
CONCLUSION
GSDME-mediated pyroptosis promotes the development of CAC by releasing HMGB1, which induces tumor cell proliferation and PCNA expression through the ERK1/2 pathway. This finding reveals a previously unrecognized link between pyroptosis and CAC tumorigenesis and offers new insight into CAC pathogenesis.
