Bidirectional Irrigation System to Treat a Difficult Wound: A Case Series.

AIMS: To date, there is no distinct principle determining whether to use irrigation under negative-pressure wound therapy (NPWT). We developed a new economical device to manage difficult wounds, employing 1 of 2 techniques depending on the wound condition. METHODS: This case series study was conducted in 12 patients with difficult wound, from 2017 to 2018. Four patients were treated with Type A bidirectional irrigation system (wound irrigation), while 8 patients were treated with Type B bidirectional irrigation system (wound irrigation combined with NPWT). RESULTS: In the Type A device group, inflammatory profiles in case I, case IV, and case VIII were not monitored due to the stability of their wound. The mean recovery period was 3.75 weeks (2-8 weeks), with decreases in 100% healing rate. In the Type B device group, we noted an average of 71% reduction in inflammatory profiles. All patients' infections were resolved or were healing, and 7 patients recovered satisfactorily. The recovery period ranged from 4 to 17 weeks, with a median value of 7 weeks. CONCLUSION: Bidirectional irrigation system decreases secondary infections and complications, and increases the healing rate in patients with difficult wound.

Scar Endometriosis Presenting as a Painful Abdominal Mass.

Abdominal wall scar endometriosis occurs in 1%-2% of women following a cesarean section delivery. We report a case of a 36-year-old woman with scar endometriosis, presenting with an acute, painful abdominal wall mass. She underwent a cesarean section 8 years before presentation. She was admitted to the emergency room for physical examination of the abdomen, which revealed a palpable mass. Abdominal computed tomography (CT) revealed an ill-defined soft-tissue lesion over the left rectus abdominis muscle (abdominal scar). Surgical removal of the abdominal wall mass was performed with adequate clearance margins with a preoperative diagnosis of postcesarean scar endometriosis. Postcesarean scar endometriosis is a rare cause of an abdominal mass; however, when this condition presents acutely, it can be difficult to diagnose. In this case, careful analysis of the patient's history, CT images, and histopathological results together confirmed the diagnosis. Surgical excision was performed under general anesthesia while maintaining adequate clearance margins.
