Laser Ablation of Pilonidal Sinus Disease: A Pilot Study.

BACKGROUND: Pilonidal disease is classically treated with wide local excision, although a number of minimally invasive approaches are currently under investigation. We aimed to determine the safety and feasibility of laser ablation of pilonidal sinus disease. IMPACT OF INNOVATION: Laser ablation provides a minimally invasive means of obliterating pilonidal sinus tracts without a need for excessive tract dilation. Laser ablation can be performed more than once on the same patient if necessary. TECHNOLOGY MATERIALS AND METHODS: This technique uses the NeoV V1470 Diode Laser (neoLaser Ltd, Caesarea, Israel) with a 2-mm probe. We performed laser ablation in adults and pediatric patients. PRELIMINARY RESULTS: We performed 27 laser ablation procedures in 25 patients, with a median operative time of 30 minutes. Eighty percent of patients reported either no pain or mild pain at the 2-week postoperative visit. The median time to return to work or school was 3 days. Eighty-eight percent of patients reported being satisfied or very satisfied with the procedure at their most recent follow-up (median, 6 mo). Eighty-two percent of patients were healed at 6 months. CONCLUSIONS AND FUTURE DIRECTIONS: Laser ablation of pilonidal disease is safe and feasible. Patients experienced short recovery time and reported low levels of pain and high levels of satisfaction.

Complicated appendicitis: Immediate operation or trial of nonoperative management?

BACKGROUND: The optimal treatment for complicated appendicitis remains controversial. We sought to compare clinical outcomes of patients with complicated appendicitis treated with an immediate operation or a trial of nonoperative management. METHODS: Adult patients (≥18 years) with complicated appendicitis were included. Patient characteristics and outcomes were compared between the immediate operation group and the nonoperative management group. RESULTS: A total of 101 patients met our inclusion criteria. Of those, 36 patients received an initial trial of nonoperative management with an 86.1% success rate. Patients who failed nonoperative management required significantly longer hospital stays than those in the immediate operation group (11 vs. 5 days). An immediate operation was performed in 65 patients. Open surgery was required in 9 patients (13.8%). Postoperatively, 7 patients (10.8%) required percutaneous drainage of intraabdominal abscess. CONCLUSIONS: Nonoperative management was successful in the majority of patients with complicated appendicitis, whereas failure of nonoperative management was associated with prolonged hospital stay. Patients who underwent an immediate operation often required percutaneous drainage of intraabdominal abscess.
