Table 1 Major risk factors and mechanistic contributors to postoperative nausea and vomiting after laparoscopic cholecystectomy
| Category | Specific factors | Mechanistic pathways involved |
| Patient-related | Female sex; younger age; history of motion sickness or prior PONV; non-smoking status | Heightened serotonergic sensitivity; autonomic imbalance |
| Anesthetic-related | Volatile anesthetics; opioids | Activation of 5-HT 3 and D2 pathways; delayed gastric emptying; vagal stimulation |
| Surgical-related | Bile duct manipulation; pneumoperitoneum | Gastrointestinal irritation; inflammatory signaling; altered bile acid dynamics |
| Physiological and biochemical | Altered gut microbiota; bile acid–serotonin interactions | Increased colonic 5-HT production; dysregulated motility |
| Perioperative factors | Anxiety; prolonged fasting; hemodynamic instability | Autonomic dysregulation; impaired gastrointestinal perfusion |
