Overview
No universal standard treatment exists for appendicitis complicated by abscess. The mainstay of treatment includes abscess drainage along with empiric antibiotics. It resolves most of the abscess. Once the abscess is resolved it is followed by appendectomy 8-12 weeks after the pharmacological treatment.
Treatment
The preferred treatment includes non-operative management such as drainage and broad spectrum IV antibiotics along with IV fluids followed by surgery which includes interval laparoscopic appendectomy. It has proved to have a high success rates up to 97% and low incidences of complications.[1][2][3][4]
Medical Therapy
Antibiotics should be started immediately once the diagnosis of abscess is made. Preoperative antibiotics have been associated with lower rates of wound and intra-abdominal infections.[5] [6]
Duration
The duration of treatment with intravenous antibiotics ranges from 5 to 10 days, until fever resolves, white blood cell count normalizes, and bowel function returns.[6]
Empiric therapy
Monotherapy with a beta-lactam/beta-lactamase inhibitor:
- Preferred regimen (1):Ampicillin-sulbactam 3 g IV q6h
- Preferred regimen (2):Ticarcillin-clavulanate 3 g IV q4h
- Preferred regimen (3):Piperacillin-tazobactam 3 g or 4.5 g IV q6h
Combination third generation cephalosporins PLUS metronidazole
- Preferred regimen (1): Ceftriaxone 1 g IV q24h AND Metronidazole 500 mg IV q8h OR 1500 mg q24h.
- Preferred regimen (2): Cefazolin 1–2 g IV q8h AND Metronidazole 500 mg IV q8–12 h OR 1500 mg q24h
- Preferred regimen (3): Cefuroxime 1.5 g IV q8h AND Metronidazole 500 mg IV q8–12 h OR 1500 mg q24h
- Preferred regimen (4): Cefotaxime 1–2 g IV q6–8 h AND Metronidazole 500 mg IV q8–12 h OR 1500 mg q24h
Alternative empiric regimens
Combination fluoroquinolone PLUS metronidazole:
- Preferred regimen (1): Ciprofloxacin 400 mg IV q12h AND Metronidazole 500 mg IV q8–12 h OR 1500 mg q24h
- Preferred regimen (2): Levofloxacin 750 mg IV q24h AND Metronidazole 500 mg IV q8–12 h OR 1500 mg q24h
Monotherapy with a carbapenem
- Preferred regimen (1): Imipenem-cilastatin 500 mg IV q6h OR 1 g q8h
- Preferred regimen (2): Meropenem 1 g IV q8h
- Preferred regimen (3): Doripenem 500 mg IV q8h
- Preferred regimen (4): Ertapenem 1 g IV q24h
Percutaneous drainage
- Percutaneous drainage can be performed under ultrasound or CT guidance, using either the Seldinger or trocar technique.[7]
- Ultrasound is limited if the abscess is small, obscured by other structures, or if precise placement is required because of nearby vessels or organs. In these cases, CT is the optimal imaging modality.[8]
- When an abscess is deep in the pelvis, depending on the specific location of the fluid collection, access may be obtained via transgluteal, transvaginal, or transrectal approaches.[9]
- If the fluid collection is sterile, a transgluteal approach is preferred because it allows for sterile technique.[8]
- Depending on the location of abscess,patient is placed in prone or supine position on the CT table
- Localization scan using CT allows in selecting a safe window of access into the collection.
- A coaxial micropuncture introducer set is advanced into the abscess under CT guidance.
- An Amplatz guidewire is advanced through the sheath and coiled within the abscess.
- After serial dilatation of the tract with a dilator, an pigtail drain is advanced over the guidewire and deployed.
