Abdominal Wall Sinus and Recurrent Abscess Formation Due to a Foreign Body Following Surgical Intervention.

The sinus tract, a tubular structure with no outlet connecting deep tissues to the skin, is a rare entity, especially in patients undergoing abdominal surgeries. The pathophysiology involves factors such as liquefaction of adipose tissue, infection, and retention of foreign bodies. Inadequate surgical drainage can lead to chronicity, culminating in the formation of an infectious sinus in the abdominal wall, clinically known as a sinus. Understanding this phenomenon is crucial to avoid recurrences and complications. A 65-year-old female patient with a history of multiple abdominal surgeries presented with pain and suprapubic discharge. Similar episodes had occurred previously. Examinations revealed a fistulous tract in the right iliac fossa. The surgical intervention included the excision of the tract, identification of points with cotton thread, and antibiotic therapy. Follow-up in the outpatient setting showed no recurrences. The presence of postoperative foreign bodies, such as sutures, can trigger recurrent local infections. Diagnosis involves imaging studies, and the type of surgical thread influences complications. Treatment aims at drainage and excision of the tract. A multidisciplinary approach is of paramount importance. The sinus, with its insidious formation, highlights the complexity of this condition. Careful selection of surgical materials, precise imaging diagnosis, and a multidisciplinary approach are essential for effective treatment. This case emphasizes the importance of clinical practice to enhance clinical outcomes and the quality of life of patients affected by this challenging condition.
