AI Article Synopsis
- Perianal fistulae often develop complications like abscesses and have specific imaging characteristics, but atypical solid mass-like lesions can also occur.
- These lesions may indicate chronic inflammation or a more serious locally aggressive cancer, which has a worse prognosis and may require extensive surgery.
- Radiologists play a critical role in recognizing these unusual findings, understanding their possible causes, and recommending tissue sampling to rule out cancer, which is key for effective surgical treatment.
Article Abstract
Perianal fistulae are commonly complicated by abscesses and ramifications, which have well-recognized imaging morphology. Less commonly, atypical findings of solid enhancing mass-like lesions with no fluid component are associated with chronic and recurrent fistulae, the etiology of which includes inflammatory masses as well as locally aggressive malignancy. The latter predicts poorer prognosis and warrants extensive surgical resection. The reading radiologist must identify the unusual appearance, be aware of the possible etiologies, and if appropriate recommend prompt tissue sampling to exclude malignancy. This is pertinent as it determines surgical management, which is crucial in achieving a potential curative outcome.

Management of Perianal Fistulizing Crohn's Disease According to Principles of Wound Repair.
Aliment Pharmacol Ther

Background: Perianal fistulizing Crohn's disease (PFCD) is a challenging and debilitating phenotype of Crohn's disease that can negatively affect quality of life. Studies have begun to uncover the physiologic mechanisms involved in wound repair as it relates to PFCD and how aberrations in these mechanisms may contribute to fistula persistence.
Aims: To review the physiologic and pathophysiologic mechanisms of wound repair in PFCD and how specific therapeutic strategies may impact their outcomes.

Crohn's disease (CD) is a chronic, complex inflammatory disorder of the gastrointestinal tract that presents significant therapeutic challenges. Despite the availability of a wide range of treatments, many patients experience primary non-response, secondary loss of response, or adverse events, limiting the overall effectiveness of current therapies. Clinical trials often report response rates below 60%, partly due to stringent inclusion criteria.

Hemorrhoids, anal fissure, anal fistula and perianal abscess are the most common benign diseases around the anus, which obviously affect people's life and work, and need to be well diagnosed and treated. Based on damage control, the treatment principle is to eliminate relevant disease symptoms and protect the anal function at the same time. Perianal benign diseases are common and frequently occurring, which can be diagnosed and treated in many non-specialist hospitals.

Introduction: Crohn's disease (CD) is a chronic inflammatory bowel disease which can affect any area of the gastrointestinal tract, including oral tissues. The complex nature of this disease demands interdisciplinary management, especially when both intestinal and oral manifestations are present.
Case: This report presents the case of a 28-year-old male patient with oral, ileo-caecal and peri-anal CD managed jointly between Gastroenterology and Oral Medicine.

Exposure to ionizing radiation can induce harmful biological effects on the human body, particularly in cases of high-dose γ-irradiation affecting the gastrointestinal tract, bone marrow, skin and lung. Such exposures lead to lethal outcomes as individuals experience a breakdown in their immune system's ability to defend against pathogens, predisposing them to sepsis-induced multiple organ failures. Mesenchymal stromal/stem cells (MSCs) possess diverse biological characteristics, including immunomodulation, anti-inflammation and tissue regeneration.
