A nurse is assessing a 52-year-old patient 6 hours after laparoscopic sleeve gastrectomy. Which assessment finding would be the priority concern requiring immediate intervention?

Left shoulder pain with abdominal distension and decreased bowel sounds indicates potential complications like retained CO2 or anastomotic leak requiring immediate assessment. Other findings (stable vitals, nausea, incisional pain) are expected post-op.

Priority Concern After Laparoscopic Sleeve Gastrectomy

The correct answer is left shoulder pain with abdominal distension and decreased bowel sounds. This combination of findings represents the highest clinical priority because it is a classic presentation of a gastric leak, which is a life-threatening postoperative complication requiring immediate intervention.

Pathophysiology and Clinical Rationale

A staple line leak after laparoscopic sleeve gastrectomy (LSG) is a serious complication, with postoperative bleeding from the staple line occurring in 0.6%-3.4% of cases ^[1]. When a leak occurs, gastric contents escape into the peritoneal cavity, causing chemical peritonitis and subsequent systemic effects. The leaked fluid and inflammatory exudate can track upward, irritating the diaphragm and phrenic nerve. This referred pain pathway manifests as left shoulder pain, also known as Kehr's sign.

The concurrent abdominal distension and decreased bowel sounds are hallmark signs of a developing paralytic ileus secondary to peritoneal irritation. As noted in the literature, gastric leaks remain a serious complication and are often diagnostically challenging ^[2]. A case report specifically describes a patient who experienced persistent dysphagia, post-prandial vomiting, and referred left shoulder pain as manifestations of a chronic gastro-diaphragmatic fistula following LSG ^[2]. This underscores that left shoulder pain in a post-gastrectomy patient is a red flag for a leak or fistula until proven otherwise.

Analysis of Other Options

Option 1 presents a heart rate of 88 beats per minute and blood pressure of 125/78 mmHg. These vital signs are within normal limits for a postoperative patient and do not indicate hemodynamic instability or an acute complication. Tachycardia and hypotension would be expected with significant hemorrhage or sepsis from an anastomotic leak, but these values are reassuring.

Option 3 describes nausea with one episode of clear, blood-tinged vomiting. A small amount of blood-tinged emesis in the early postoperative period can occur due to irritation of the gastric mucosa or residual blood from the surgical field. While it warrants continued monitoring, it is not the priority finding unless it becomes copious or is accompanied by hemodynamic changes. Postoperative gastrointestinal complications are distressing, but this isolated finding is less immediately threatening than a suspected leak .

Option 4 lists incisional pain rated 6/10 at trocar sites with minimal serous drainage. Incisional pain and a small amount of serous drainage are expected findings after laparoscopic surgery. The pain rating, while significant, is an expected postoperative symptom and does not suggest a life-threatening complication. Management would include pain medication and wound care, not emergent intervention.

Clinical Decision-Making and Nursing Priority

Using the ABC (Airway, Breathing, Circulation) framework and the concept of acute versus chronic complications, a suspected gastric leak takes precedence because it can rapidly progress to sepsis, peritonitis, and hemodynamic collapse. The nurse must recognize that left shoulder pain in this context is not a musculoskeletal issue but a sign of peritoneal irritation. Immediate nursing actions include notifying the surgeon, keeping the patient NPO, preparing for diagnostic imaging or endoscopic evaluation, and closely monitoring vital signs for signs of systemic infection. Studies on modifications like omentopexy aim to reduce these postoperative complications, highlighting the clinical significance of leak prevention and early detection .
