A patient with cholecystitis undergoes laparoscopic surgery and is placed in supine position postoperatively. The patient develops shoulder pain. This is due to which complication?

Appeared in: NORCET 10 Mains

Explanation

Shoulder pain after laparoscopic surgery is a classic example of referred pain.
Carbon dioxide (CO₂) used to inflate the abdomen (insufflation) can remain trapped and irritate the diaphragm.
This irritation stimulates the phrenic nerve, which shares a common nerve pathway (C3-C5 vertebrae) with nerves supplying the shoulder.
The brain interprets the signal from the diaphragm as pain originating in the shoulder.
This is a common, expected, and temporary side effect that usually resolves as the gas is absorbed by the body.

Option A: Decreased bowel sounds (paralytic ileus) are common after abdominal surgery due to anesthesia but do not cause shoulder pain. They indicate slowed gastrointestinal motility.
Option C: A urethral stricture is a narrowing of the urethra. It is a urological issue and has no connection to a cholecystectomy or the symptom of shoulder pain.
Option D: A wound infection would typically appear several days (3-6 days) post-surgery, not immediately. Symptoms would be localized to the incision site (redness, swelling, pus, warmth) and may include fever.

Clinical Relevance

Nursing practice connection: Use the key finding related to Postoperative complications of laparoscopic surgery to guide bedside assessment, documentation, and the next nursing action.
Recognizing referred shoulder pain is crucial for nurses to provide accurate patient education and reassurance, preventing unnecessary anxiety about a more serious complication like a heart attack.
Prompt implementation of simple nursing interventions like ambulation and positioning can significantly alleviate the patient's discomfort and speed up recovery.
What if? If the shoulder pain was on the left side, sharp, and accompanied by hypotension, tachycardia, and abdominal guarding, the nurse should consider a more serious complication like splenic injury or internal bleeding, which would require immediate medical escalation, rather than assuming it is simple referred pain.

How to Approach the Question

First, identify the core elements of the clinical scenario: a patient who has just had laparoscopic surgery.
Next, note the specific symptom presented: shoulder pain.
Connect the procedure (laparoscopy) with its known, common side effects. Recall that gas is used to inflate the abdomen during this procedure.
Evaluate the options. Consider the pathophysiology of each option and whether it can cause shoulder pain in this context.
Eliminate options that are anatomically or temporally inconsistent. Urethral stricture is in a different body system. Wound infection occurs later. Decreased bowel sounds don't cause pain in the shoulder.
Select the option that provides a direct physiological explanation for the symptom in the context of the procedure: CO₂ gas irritating the diaphragm and phrenic nerve, causing referred pain.

Concept Tested & Keywords

Concept Tested: Postoperative complications of laparoscopic surgery
Stem keywords: cholecystitis, laparoscopic surgery, postoperatively, shoulder pain
Lead-in keywords: due to which complication
Clinical cues: The key clinical cue is the development of shoulder pain after a laparoscopic procedure, which strongly points towards referred pain from diaphragmatic irritation.
