Tachycardia and Shoulder Pain After Sleeve Gastrectomy
A 39-year-old man is on postoperative day 3 after a laparoscopic sleeve gastrectomy (BMI 46 kg/m²). He was discharged on postoperative day 1 and returns with nausea, left shoulder pain, and inability to tolerate fluids. Heart rate is 118/min, blood pressure 104/66 mm Hg, temperature 38.0°C, respiratory rate 22/min, and SpO2 95% on room air. Urine output is 20 mL/hr. The abdomen is soft but tender in the left upper quadrant. WBC is 15,200/µL, lactate 2.4 mmol/L, and creatinine 1.3 mg/dL (baseline 0.9). He has no chest pain or leg swelling. The program has no in-house bariatric surgeon overnight, but a general surgeon is available and transfer to a bariatric center is 2 hours away.
1. What is the immediate assessment and differential diagnosis, and what should be done in the first hour?

This is a possible staple-line leak with early sepsis until proven otherwise. The combination of tachycardia, fever, left shoulder pain, oliguria, rising creatinine, and leukocytosis on POD 3 is the classic window for a sleeve leak. Left shoulder pain suggests diaphragmatic irritation. The differential also includes pulmonary embolism, atelectasis or pneumonia, dehydration, cholecystitis, pancreatitis, and urinary infection.
Immediate priorities: NPO, two large-bore IVs, balanced crystalloid resuscitation, urine output monitoring, broad-spectrum antibiotics after cultures, antiemetics, and supplemental oxygen. Call the bariatric surgeon now. Do not give oral contrast or feed the patient. Check ECG and consider CTA for PE if the chest picture dominates, but do not delay leak management.
2. What diagnostic workup and initial management would you order?

Diagnosis: CT of the abdomen and pelvis with water-soluble oral contrast is the preferred initial study; it can show a collection, extraluminal contrast, or pneumoperitoneum. A plain film is not sensitive. If CT is negative but suspicion remains high, repeat imaging, endoscopy, or surgical exploration may be needed. Blood cultures, lactate, CBC, CMP, and coagulation studies should be sent.
Treatment: start broad-spectrum antibiotics covering gram-negative and anaerobic organisms, provide aggressive fluids, and place a urinary catheter. If a drainable collection is present and the patient is stable, percutaneous drainage plus endoscopic stent and enteral or parenteral nutrition may be considered. If there is peritonitis, hemodynamic instability, or a large free leak, proceed to washout and drainage. Continue VTE prophylaxis once bleeding risk is assessed.
3. How do you decide between transfer, nonoperative management, and reoperation?
Read the worked answer
Disposition depends on physiology and local resources. This patient has tachycardia, oliguria, and a lactate of 2.4 mmol/L, so he is not a candidate for outpatient management. If the local hospital has no bariatric surgeon, stabilize and transfer to a bariatric center after starting antibiotics and fluids; do not wait for imaging if he deteriorates. The 2-hour transfer is acceptable only with monitored transport and a receiving bariatric team.
Operative criteria: diffuse peritonitis, hemodynamic instability, worsening lactate, free contrast leak, or failure of nonoperative drainage. Nonoperative pathway: stable patient, contained collection, no sepsis, and access to interventional radiology and endoscopy. Either way, the patient needs ICU-level monitoring, nutrition support, and a clear plan for repeat imaging.
