Management of a Confirmed Staple Line Leak
A 47-year-old woman, three weeks after laparoscopic sleeve gastrectomy, has generalised peritonitis, temperature 38.9 °C, heart rate 125 beats/min, and blood pressure 90/55 mm Hg. Contrast-enhanced CT shows extravasation of oral contrast at the proximal staple line with a large left subphrenic collection. Which of the following is the most appropriate management?
- A.Therapeutic anticoagulation and observation
- B.Nil by mouth with intravenous antibiotics
- C.Urgent surgical exploration and lavageCorrect
- D.Endoscopic covered stent placement
Explanation
This patient has a confirmed proximal staple line leak with generalised peritonitis and haemodynamic compromise, which is a surgical emergency. The two governing principles of sepsis management are source control and drainage of the contaminated space, and neither can be achieved with medical therapy alone. Urgent exploration, laparoscopic or open, allows washout of the peritoneal cavity, identification and repair or buttressing of the defect where possible, and placement of wide drains adjacent to the leak. Enteral access by feeding jejunostomy is often established at the same operation, since these patients need prolonged nutritional support. Resuscitation, broad-spectrum antibiotics, and nil by mouth are essential adjuncts but are supportive measures rather than definitive treatment, and relying on them alone in a septic patient with peritonitis is fatal. Endoscopic covered stenting, internal drainage, or percutaneous drainage are excellent options for a small, contained, well-drained leak in a stable patient, but they do not clear diffuse peritoneal contamination. Anticoagulation has no role unless a thromboembolic event is proven. Early source control, ideally within hours of diagnosis, is the strongest determinant of survival in post-bariatric leak sepsis.
Why each option
- A.
- Anticoagulation treats venous thromboembolism and has no role in the management of an anastomotic or staple line leak.
- B.
- Nil by mouth, fluids, and antibiotics are necessary supportive measures but do not achieve source control in a patient with peritonitis.
- C.
- Correct. Diffuse peritonitis with a confirmed leak requires urgent operative washout, drainage, and repair of the defect.
- D.
- Endoscopic stenting suits a small contained leak in a stable patient and cannot clear established generalised peritoneal contamination.
