Review
Perianal symptoms occur in up to 50% of patients with Crohn's disease in other parts of the gastrointestinal tract, and in 5% of patients it is the first manifestation of the disease. The perianal area is often under stress in patients with Crohn's disease, because of the diarrhea, and the fecal urgency, frequency, and incontinence caused by proximal disease. Symptomatic perianal disease can therefore be due to the effects of the stress on an otherwise normal anus, or the result of Crohn's disease in the low rectum and/or perianal tissues themselves. This key distinction should drive the investigation and management of anal and perianal symptoms in patients with Crohn's disease. In this review, the evaluation and management of the various manifestations of Crohn's disease in the perineum and perianal tissues will be described.

Despite the fact that countless patients suffer from anal problems, there tends to be a lack of understanding of anal health care. Unfortunately, this leads to incorrect diagnoses and treatments. When treating a patient with an anal complaint, the primary goals are to first diagnose the etiology of the symptoms correctly, then to provide an effective and appropriate treatment strategy.The first step in this process is to take an accurate history and physical examination. Specific questions include details about bowel habits, anal hygiene, and fiber supplementation. Specific components of the physical examination include an external anal examination, a digital rectal examination, and anoscopy if appropriate.Common diagnoses include pruritus ani, anal fissures, hemorrhoids, anal abscess or fistula, fecal incontinence, and anal skin tags. However, each problem presents differently and requires a different approach for management. It is of paramount importance that the correct diagnosis is reached. Common errors include an inaccurate diagnosis of hemorrhoids when other pathology is present and subsequent treatment with a steroid product, which is harmful to the anal area.Most of these problems can be avoided by improving bowel habits. Adequate fiber intake with 30 g to 40 g daily is important for many reasons, including improving the quality of stool and preventing colorectal and anal diseases.In this Special Report, we provide an overview of commonly encountered anal problems, their presentation, initial treatment options, and recommendations for referral to specialists.

Review
Anal fissure is a common ailment, however, the pathophysiology and optimal treatment strategy is unclear. Anal fissures may be classified as acute or chronic. Acute fissures are effectively treated and prevented with conservative measures, whereas chronic fissures typically require medical or surgical therapy. Invasive interventions have superior healing rates compared with local medical therapies, but may cause persistent incontinence. New interventions are constantly introduced and may be of value in patients with high risk of incontinence, but more evidence is currently needed.

OBJECTIVES
Surgical management of chronic anal fissure can result in permanent fecal incontinence. Topical treatments have a lower risk of severe complication and are less expensive than surgical intervention. Rates of healing and compliance with topical agents vary in the reported literature. The aim of this study was to compare healing rates, incidence of headaches, and recurrence rates of chronic anal fissure in patients treated with topical diltiazem (DTZ) and topical glyceryl-trinitrate (GTN), with a view of identifying which agent should be used as first line non-operative therapy.
MATERIAL AND METHODS
Randomized controlled trials (RCTs), published since January 2000, comparing topical DTZ and GTN for treatment of chronic anal fissure were identified and compared. End points included healing rates, headache due to treatment, and late recurrence (>12 weeks). A random effects meta-analysis model was used to compare outcomes.
RESULTS
All studies used 2% DTZ and 0.2% or 0.5% GTN, and treatment was continued twice daily for between 6-12 weeks. Nine RCTs compared rates of healing with topical DTZ (n= 379) and GTN (n= 351), there was no difference between the two groups [RR 1.04 (0.93-1.16), p= 0.48]. Eight RCTs reviewed incidence of headaches, DTZ was better tolerated [RR 0.15 (0.07-0.34), p <0.00001]. Four RCTs reported late recurrence rates, DTZ was superior [RR 0.51 (0.27-0.96), p= 0.04].
CONCLUSION
Topical DTZ and GTN result in comparable healing rates; however, DTZ is superior with regards to headaches and late recurrence rates. DTZ should therefore be considered as first line non-operative treatment for chronic anal fissure.

Review
Anal stenosis, which develops as a result of aggressive excisional hemorrhoidectomy, especially with the stoutly use of advanced technologies (LigaSure, ultrasonic dissector, laser, etc.), has become common, causing significant deterioration in the patient's quality of life. Although non-surgical treatment is effective for mild anal stenosis, surgical reconstruction is unavoidable for moderate to severe anal stenosis that causes distressing, severe anal pain, and inability to defecate. The problem in anal stenosis, unlike anal fissure, is that the skin does not stretch as a result of chronic fibrosis due to surgery. Therefore, the application of lateral internal sphincterotomy does not provide satisfactory results in the treatment of anal stenosis. Surgical treatment methods are based on the use of flaps of different shapes and sizes to reconstruct the anal caliber and flexibility. This article aims to summarize most-used surgical techniques for anal stenosis regarding functional and surgical outcomes.

Meta-Analysis Review
BACKGROUND
There are no consensus guidelines on the optimal dose or injection site of botulinum toxin (BT) for chronic anal fissure (CAF). The objective of this study was to determine the appropriate dose and injection site of BT for CAF by comparing healing rate and adverse effects (incontinence and recurrence).
METHODS
MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus were searched from inception through May 31, 2021. Randomized controlled trials evaluating healing and adverse effects of BT injection for CAF published in any language were selected. Multiple treatment comparisons and ranking were performed using a two-stage network meta-analysis, and results were graded by Confidence in Network Meta-Analysis tool.
RESULTS
Twenty-seven trials involving 1880 patients were included. The results demonstrated that high-dose-BT had significantly higher short-term healing when injected out of the fissure (OF) site than each side of the fissure (SF) site, with a risk ratio (RR) of 2.12 (1.08, 4.15); low-dose-BT did not show any difference across OF and SF site with RR of 1.20 (0.85, 1.68). High-dose-BT at the OF site showed similar healing to low-dose-BT at the same site (RR of 1.02 (0.79, 1.31)) but with a higher risk of incontinence with RR of 3.54 (0.85, 14.76). In contrast, high-dose-BT at the SF site showed lower healing compared to low-dose-BT at the same site with RR of 0.57 (0.29, 1.14). Both high-dose-BT and low-dose-BT at the OF site had higher recurrence than high-dose-BT or low-dose-BT at the SF site with RR of 2.08 (0.33, 13.11) and 1.89 (0.60, 5.94), respectively.
CONCLUSIONS
Given moderate level of evidence, low-dose BT is optimal; injection out of the fissure site improves short-term outcomes while injection each side of the fissure site tends to reduce recurrence in the longer term.
