  • Vital signs: Temperature 39.2°C, Pulse 110/min, BP 100/70 mmHg, RR 22/min, SpO2 96% on room air
  • Physical examination: Diffuse abdominal tenderness with guarding, decreased bowel sounds, abdominal distension

Initial Investigations:

  • Complete blood count: WBC 18,500/mm³ with neutrophilia (85%)

  • Abdominal X-ray: Multiple air-fluid levels, dilated small bowel loops
  • CT abdomen with contrast: Small bowel obstruction with thickened bowel wall, mesenteric fat stranding, and a small intra-abdominal abscess (4.5 cm) in the right lower quadrant

Initial Management Plan:

  1. NPO (nil per oral) status
  2. Nasogastric tube placement for decompression
  3. IV fluid resuscitation with isotonic crystalloids at 150 ml/hr
  4. Antibiotic therapy: Piperacillin-tazobactam 4.5g IV q8h and Metronidazole 500mg IV q8h 1
  5. Electrolyte correction: Potassium supplementation

  7. Percutaneous drainage of the intra-abdominal abscess under CT guidance 1
  8. Foley catheter insertion for strict input/output monitoring 1
  9. Pain management: Morphine 4mg IV q4h PRN

Doctor's Progress Notes - Day 2

Morning Note (8:00 AM)

Patient's temperature decreased to 38.0°C. Abdominal pain improved to 4/10. Nasogastric output 500ml overnight. Abscess drain output 80ml. Laboratory results show WBC 16,200/mm³, CRP 160 mg/L. Electrolytes improving with K+ 3.6 mEq/L. Continue current management.

Afternoon Note (2:00 PM)

Preliminary culture from abscess shows mixed enteric bacteria. Continuing antibiotics as per sensitivity. Nasogastric output decreased to 350ml since morning. Abdominal distension slightly improved. Patient tolerating treatment well.

Evening Note (8:00 PM)

Patient afebrile (37.8°C). Abdominal examination shows decreased tenderness. Bowel sounds still hypoactive. Plan to continue current management and reassess for signs of resolution of obstruction tomorrow.

Nursing Notes - Day 2

  • Repeat CT scan on day 5 showed decreased abscess size (1.5 cm) and improvement in bowel wall thickening
  • Nasogastric tube clamped intermittently on day 5 to assess tolerance
  • Clear liquid diet initiated on day 5 and tolerated well

Days 6-10 Summary

Clinical Progress:

  • Complete resolution of fever
  • WBC normalized to 9,500/mm³
  • Nasogastric tube removed on day 7
  • Diet advanced to soft diet by day 8
  • Bowel movements resumed on day 7

  • Follow-up appointment scheduled for 2 weeks after discharge

Discharge Summary - Day 15

Diagnosis: Infective intestinal obstruction with intra-abdominal abscess, successfully treated with conservative management and percutaneous drainage.

Hospital Course:

  • 34-year-old male presented with abdominal pain, vomiting, and fever
  • Diagnosed with small bowel obstruction and intra-abdominal abscess
  • Managed with nasogastric decompression, IV fluids, antibiotics, and percutaneous drainage
  • Gradual improvement with resolution of obstruction and infection
  • No surgical intervention required

Discharge Medications:

  • Probiotic supplement daily for 1 month
  • No other medications required

Follow-up Instructions:

  • Outpatient clinic visit in 2 weeks
  • Return to normal activities gradually over 2-4 weeks
  • Return immediately if experiencing recurrent abdominal pain, fever, vomiting, or constipation

Justification for 15-day hospitalization: The extended hospitalization was justified due to:

  1. Presence of both intestinal obstruction and intra-abdominal abscess requiring careful monitoring
  2. Need for percutaneous drainage and ensuring adequate drainage of abscess
  3. Gradual resolution of obstruction requiring prolonged bowel rest and decompression
  4. Need for completion of parenteral antibiotic therapy for complicated intra-abdominal infection 1
  5. Ensuring complete resolution of infection before discharge to prevent recurrence 1

This conservative approach with percutaneous drainage avoided the need for surgical intervention, reducing the risk of surgical complications and prolonged recovery 1.
