I now have all the information needed for a thorough answer. Here is a comprehensive summary on the treatment of splenic abscess.

Treatment of Splenic Abscess

(Note: I interpret "975 cc" in your query as likely a typo for "975 cc" as an abscess size, or possibly a dictation artifact. The treatment approach below covers all sizes and clinical scenarios.)

Background

Splenic abscess is uncommon (incidence 0.14-0.76%) but carries significant mortality if untreated. It arises most often from:

Hematogenous spread - infective endocarditis, IV drug use, bacteremia
Contiguous infection - pancreatic necrosis, bowel perforation
Hemoglobinopathy (e.g., sickle cell disease)
Immunosuppression - HIV, chemotherapy, chronic steroids
Trauma

CT scan with IV contrast (95% sensitivity/specificity) is the gold-standard imaging and also characterizes the abscess as unilocular vs. multilocular.

Treatment Principles

Treatment rests on three pillars:

1. Antibiotics

Start empiric broad-spectrum antibiotics within 1 hour for septic patients (Surviving Sepsis Guidelines)
Most abscesses are polymicrobial, so broad initial coverage is essential
Common organisms: Streptococcus spp., Staphylococcus aureus, E. coli, Salmonella, Klebsiella, Proteus, Bacteroides, Candida spp.
In immunocompromised patients, add coverage for Candida and Mycobacterium
Continue antibiotics for a minimum of 14 days; continue until percutaneous drains are removed
Narrow therapy once culture/sensitivity results available

2. Percutaneous Drainage (Preferred First-Line for Unilocular Abscess)

Performed under CT or ultrasound guidance by interventional radiology
Success rate: 67-100% in reported series
Indications: Unilocular abscess, hemodynamically stable patient
Contraindication to note: Avoid transpleural drainage (risk of empyema/seeding)
Send drain cultures for microbiologic identification
If unilocular - most likely to achieve complete resolution with this approach
If multilocular - often requires multiple drains and may ultimately still need splenectomy

3. Splenectomy (Definitive/Salvage)

Situation	Role of Splenectomy
Failure of percutaneous drainage	Recommended
Multiloculated abscess	Often required; open or laparoscopic
Hemodynamically unstable (unable to tolerate IR)	Emergent open splenectomy
Multiple abscesses throughout spleen	Preferred (spleen is part of overwhelming sepsis)
Pediatric patients	Percutaneous drainage preferred to preserve splenic function

Laparoscopic splenectomy is safe and feasible for splenic abscess and is the gold standard for elective/stable cases
Open splenectomy is used for hemodynamic instability or when laparoscopic approach fails
All patients undergoing splenectomy should receive vaccinations for encapsulated organisms (pneumococcus, H. influenzae type B, meningococcus, seasonal flu) - ideally at least 2 weeks pre-operatively

                  └── Multilocular / Multiple abscesses ──► Splenectomy (lap or open)

Post-Splenectomy Care

Monitor for early complications: intra-abdominal abscess, pleural effusion, empyema (treat with image-guided drainage)
Long-term: risk of overwhelming post-splenectomy sepsis (OPSS) - mitigated by vaccination
