Clinical Assessment

1. Midline wound dehiscence with fecal fistula — fecal content oozing from the midline incision
2. Ileostomy retraction — the stoma has receded below skin level
3. Severe hypoalbuminemia (albumin = 2 g/dL) — indicating significant malnutrition and impaired wound healing

Pathophysiology of the Situation

Next Line of Management

Step 1 — Immediate Resuscitation and Stabilization (First Hours)

• IV fluid resuscitation — correct dehydration and electrolyte deficits aggressively. Fecal fistulas cause massive fluid and electrolyte loss (Na⁺, K⁺, bicarbonate).
• Broad-spectrum antibiotics — cover aerobic and anaerobic gut flora (e.g., piperacillin-tazobactam or meropenem ± metronidazole). Fecal contamination of the wound indicates local/systemic sepsis.
• Blood investigations: CBC, RFT, electrolytes, blood culture, wound swab culture, serum prealbumin, CRP.
• CT abdomen with contrast — critical to identify undrained abscesses, assess residual bowel viability, delineate fistula anatomy, and rule out distal obstruction. This guides whether percutaneous drainage is needed. — Sabiston Textbook of Surgery

Step 2 — Sepsis Control

• Drain any intra-abdominal collections — percutaneous CT-guided drainage preferred; avoid reoperation if possible at this stage in a malnourished patient.
• Check and remove/replace any infected IV lines; rule out UTI, pulmonary infection as concurrent foci.
• Sepsis control is the most common cause of death in small bowel fistula patients; it takes priority. — Sabiston Textbook of Surgery, p. 1983

Step 3 — Wound Management and Fistula Effluent Control

• Do NOT attempt primary re-suture of the midline wound at this stage. The wound is contaminated, the patient is malnourished, and resuturing will fail again.
• Retracted ileostomy: Apply a convex pouching system (convex faceplate + ostomy belt) to create a seal around the retracted stoma. This is the first-line conservative management. Stoma nurses (wound/ostomy care nurses) are essential here.
• Wound with fecal fistula: The goal is to isolate the fistula effluent from the wound and protect perilesional skin:
  • Apply a wound manager bag or fistula pouch over the fistula opening to collect output accurately and measure it.
  • Protect surrounding skin with zinc oxide paste, karaya powder, or Stomahesive barriers. — Sabiston Textbook of Surgery, p. 1983
  • If output is high (>500 mL/day), consider a sump suction drain placed into the fistula tract for drainage.
  • Negative pressure wound therapy (NPWT/VAC) can be applied to the surrounding wound bed — with careful isolation of the fistula opening from the VAC sponge (use a silicone barrier or petroleum jelly gauze directly over exposed bowel to avoid iatrogenic fistula extension).
  • Proton pump inhibitors (e.g., pantoprazole IV) to reduce GI secretions.

Step 4 — Nutritional Rehabilitation (Critical Priority)

• Total Parenteral Nutrition (TPN) is the preferred route given:
  • Active fecal fistula (high output likely since this is ileal)
  • Wound contamination
  • Risk of increasing fistula output with enteral feeding
  • TPN significantly increases spontaneous fistula closure rates without increasing mortality. — Sabiston Textbook of Surgery, p. 630
• Protein target: 1.5–2.0 g/kg/day (higher end given fistula losses). — Current Surgical Therapy 14e, p. 1646
• If fistula output is low (<200 mL/day) or distal (which is less likely here as this is ileal), EN can be considered with close monitoring of output.
• Octreotide (somatostatin analogue) 100–300 mcg SC TID — consider for high-output fistula (>500 mL/day) to reduce secretions and potentially enhance closure. — Current Surgical Therapy 14e
• Correct micronutrient deficiencies (zinc, vitamin C, B-complex — essential for wound healing).
• Repeat albumin and prealbumin weekly to track response.

Step 5 — Stoma Revision Decision

• If the convex pouching system fails and the retracted stoma cannot be managed conservatively (fecal spillage uncontrolled, ischemia, peristomal skin breakdown), early stoma revision (within days) may be necessary — a limited procedure under GA, re-mobilizing the bowel limb and re-siting the stoma.
• If the retraction is mild and pouching is effective, defer revision.

Step 6 — Definitive Surgery Timing (Delayed)

• Wedge excision or segmental resection with primary anastomosis
• Careful adhesiolysis, minimize number of anastomoses
• Cover sutures with viable tissue (omentum)

POD 8 | Wound dehiscence + fecal fistula + stoma retraction + albumin 2

STOMA: Convex pouching system / consider early revision if pouching fails
         ↓
NUTRITION: TPN (1.5–2 g/kg/day protein) + octreotide if high output

DEFINITIVE SURGERY: Resection + anastomosis

Key Principles

• No re-suturing the midline wound now — it will fail in the face of contamination and hypoalbuminemia.
• No immediate reoperation for the fistula — septic abdomen with poor nutrition is a setup for anastomotic failure.
• The classic mnemonic for ECF management is SNAP: Sepsis control → Nutrition → Anatomy of the fistula (imaging) → Procedure (definitive surgery).
• Mortality in this scenario is primarily driven by uncontrolled sepsis — not by the fistula output per se. — Sabiston Textbook of Surgery, p. 1983
