Perforated Acute Appendicitis with Percutaneous Abscess Drainage

July 1, 2015

​Pre drain images showing RLQ abscess and appendicolith. 

 

Video of the drainage procedure. This was done with the patient prone, but I flipped it to compare with the pre-drain images. I had to get the drain between the coln and psoas, while angling caudad into the large abscess in the pelvis. Note the appendicolith on the final images.

 

Percutaneous abscess drainage in patients with perforated acute appendicitis: effectiveness, safety, and prediction of outcome: "CT-guided percutaneous drainage is both effective and safe in the treatment of patients with acute appendicitis complicated by perforation and abscess. The clinical and technical success rates are high."

Management of Complicated Appendicitis in the Pediatric Population: When Surgery Doesn't Cut It: "The management of complicated appendicitis in children has evolved significantly over the last century. What initially was a surgeon's dilemma is becoming the interventional radiologist's task because image-guided percutaneous drainage of abscesses from a ruptured appendix obviates the need for urgent surgery and allows for selective interval appendectomy at the surgeon's discretion (versus conservative nonoperative management in selected cases). This paradigm shift places the onus on the interventional radiologist to recognize when the procedure is emergently indicated and to be cognizant of the special needs of a pediatric patient."

The NOTA Study (Non Operative Treatment for Acute Appendicitis): prospective study on the efficacy and safety of antibiotics (amoxicillin and clavulanic acid) for treating patients with right lower quadrant abdominal pain and long-term follow-up of conservatively treated suspected appendicitis: "Antibiotics for suspected acute appendicitis are safe and effective and may avoid unnecessary appendectomy, reducing operation rate, surgical risks, and overall costs. After 2 years of follow-up, recurrences of nonoperatively treated right lower quadrant abdominal pain are less than 14% and may be safely and effectively treated with further antibiotics."
