Suprapubic sinus

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.

Ultrasound Evaluation of Dermal Sinuses/Fistulas in Pediatric Patients

A dermal sinus/fistula is a common condition; the relevant department should be consulted for appropriate treatment. It is important for radiologists to have adequate knowledge of these conditions to provide the correct diagnosis and recommend subsequent management. This review describes the following lesions: preauricular sinus, midline sinus of the upper lip, nasal dermoid sinus cyst, cheek fistula, first branchial cleft anomaly/sublingual branchial cleft anomaly, thyroglossal duct cyst/fistula, lateral cervical sinus/fistula, congenital dermal sinus/fistula of the anterior chest region, congenital skin sinus/fistula with a sternal cleft, and congenital prepubic sinus. On the basis of the skin orifice location and ultrasound images, radiologists can provide useful information to physicians.

Suprapubic versus prepubic sinus: a literature review

Urachal sinus usually presents with umbilical discharge and the opening can rarely be located between the umbilicus and the symphysis pubis and the so called suprapubic sinus (SPS). There is another different entity of cases reported in literature with a similar presentation but with an opening anywhere between the umbilicus and symphysis pubis but differs from SPS in the pathway of the tract and the epithelial lining. We report a case of a 2-year-old boy presenting with a prepubic sinus that was managed with surgical excision. After a thorough literature review, we compare our case to other prepubic and SPS.
