Incarcerated Umbilical Hernia in a Child-Pugh B Cirrhotic: Operating on a High-Risk Patient
A 64-year-old man with alcohol-related cirrhosis (Child-Pugh B, MELD 15, diuretic-controlled ascites) presents with a painful umbilical swelling that appeared 8 hours ago and cannot be reduced. He has vomited twice. Temperature 37.8 °C, heart rate 104/min, blood pressure 112/70 mmHg. The hernia is 4 cm, tense, with overlying skin erythema but no necrosis or crepitus. The abdomen is distended and tympanic with mild generalised tenderness, no rigidity. CT shows a 3 cm umbilical defect containing small bowel with a closed-loop configuration and adjacent mesenteric stranding, but no free gas and no pneumatosis. White cell count 14.2 ×10⁹/L, platelets 96 ×10⁹/L, INR 1.6, bilirubin 42 µmol/L, albumin 27 g/L, creatinine 104 µmol/L, lactate 2.1 mmol/L. The anaesthetist is concerned about the operative risk and asks you to justify your plan.
1. The anaesthetist asks you to justify operating. How do you weigh the risks, and what do you do in the first three hours to optimise him?

The risk calculus. Emergency abdominal surgery in a Child-Pugh B patient with ascites, MELD 15, INR 1.6, platelets 96 ×10⁹/L and albumin 27 g/L carries roughly a 15–25% 30-day mortality and a high rate of decompensation, bleeding and ascitic leakage. However, a closed-loop obstruction does not decompress with a nasogastric tube; the CT already shows stranding suggesting impaired perfusion, and irreversible strangulation carries a mortality far above 25%. The decision is therefore to operate on a strangulated obstruction after a short, focused period of optimisation, not to observe and hope.
First three hours.
- Nasogastric tube, nil by mouth, urinary catheter, hourly output, and fluid replacement guided by output rather than a fixed volume, because over-resuscitation worsens ascites and under-resuscitation worsens renal function.
- Correct potassium and magnesium; give vitamin K 10 mg IV.
- Blood products ready: aim for platelets above 50 ×10⁹/L before incision, and consider fresh frozen plasma or fibrinogen if there is clinical bleeding, accepting that INR 1.6 alone is not an absolute barrier to laparotomy.
- Intravenous antibiotics covering enteric organisms and anaerobes (for example co-amoxiclav and metronidazole, or piperacillin–tazobactam).
- Inform hepatology and critical care, book a high-dependency bed, arterial line, warm the theatre, discuss the high risk and the possibility of stoma with the patient and family, and document that discussion.
2. Describe your operative approach and how you decide between primary suture repair, mesh and damage control, including what you would do if the incarcerated bowel is non-viable.

Approach. A midline laparotomy gives proper access to assess the bowel and to perform a safe adhesiolysis; a small periumbilical incision incorporating the hernia sac is an alternative if the defect is easily accessible and the bowel looks viable. Open the sac carefully, divide the constricting ring under direct vision, and deliver the bowel.
Bowel assessment. Warm packs for 10 minutes, then judge colour, peristalsis, bleeding from the cut edge and a Doppler signal. Resect if clearly dead. If viable, reduce it and resect nothing. If a small patch is doubtful, resect rather than leave ischaemic bowel inside the abdomen.
Repair decision - this is the judgement point.
- Gross contamination or bowel resection: avoid permanent synthetic mesh. Close the fascia with non-absorbable sutures; a biologic mesh is an alternative if the field is clean enough and the patient can afford it.
- Clean case, no resection, small defect: a lightweight mesh is oncologically and technically defensible, but in a cirrhotic with ascites recurrence is high and mesh infection would be catastrophic. Suture repair with a Mayo-type overlap is a reasonable choice, accepting a higher recurrence rate.
- Unstable or coagulopathic: damage control with temporary abdominal closure and a planned second look at 24–48 hours.
If the bowel is non-viable. Resect with primary anastomosis only if the patient is stable and contamination is limited; otherwise end stoma. Close the fascia, close skin loosely or leave it open, and do not place a drain through the defect.
3. On day 2 he has worsening ascites, creatinine 180 µmol/L and a rising bilirubin. Give your differential diagnosis and the investigations and treatment you would initiate.

Differential.
- Intra-abdominal collection or anastomotic/enterotomy leak from the operation.
- Spontaneous bacterial peritonitis.
- Pre-renal acute kidney injury from hypovolaemia, third spacing or over-diuresis.
- Hepatorenal syndrome, which is a diagnosis of exclusion and requires absence of shock, no ongoing nephrotoxin exposure and failure of volume expansion.
- Portal vein thrombosis, contrast nephropathy and drug-induced injury.
Investigations. Diagnostic paracentesis with ascitic fluid cell count, differential, albumin and culture (a polymorphonuclear count above 250 cells/mm³ defines spontaneous bacterial peritonitis). Blood and urine cultures, full biochemistry and coagulation, lactate. Ultrasound of the liver and portal vein. Cross-sectional imaging if there is any suspicion of a leak or collection, with attention to renal function and hydration before contrast.
Treatment. Hold diuretics. Give albumin 1 g/kg (1.5 g/kg on day 3) if spontaneous bacterial peritonitis is diagnosed, with intravenous cefotaxime or a comparable third-generation cephalosporin. If hepatorenal syndrome is suspected after volume challenge, start terlipressin plus albumin and involve hepatology. Avoid NSAIDs, aminoglycosides and nephrotoxic contrast. Drain any collection. If the leak is confirmed, return to theatre; the transplant team should know about a potential candidate before the creatinine climbs further.
