Videolaparoscopic cholecystectomy for acute cholecystitis: analyzing conversion risk factors

Area of Science:

• Gastrointestinal Surgery
• Surgical Outcomes Research

Background:

• Acute cholecystitis frequently requires surgical intervention, with videolaparoscopic cholecystectomy being the preferred approach.
• Conversion to laparotomy during cholecystectomy can impact patient outcomes and resource utilization.

Purpose of the Study:

• To identify independent predictive factors for conversion from videolaparoscopic cholecystectomy to laparotomy in patients with acute cholecystitis.
• To inform surgical decision-making and patient risk stratification.

Main Methods:

• Prospective study of 176 consecutive patients undergoing videolaparoscopic cholecystectomy for acute cholecystitis.
• Data collected included patient demographics, symptom duration, American Society of Anesthesia (ASA) risk, leukocytosis, operative time, and conversion rates.
• Statistical analysis to identify independent risk factors for conversion.

Main Results:

• A conversion rate of 32.3% (57 out of 176 patients) to laparotomy was observed.
• Independent predictors of conversion included advanced age, higher ASA risk, longer symptom duration, elevated leukocytosis, and increased operative time.
• These factors were identified as significant independent conversion risk factors.

Conclusions:

• Preoperative and intraoperative factors such as age, ASA risk, symptom duration, leukocytosis, and operative time are crucial for predicting conversion.
• Awareness of these risk factors can aid surgeons in preparing for potential laparotomy and managing patient expectations.
• Further research could explore strategies to mitigate these conversion risks.
