Laparoscopic cholecystectomy: do risk factors for a prolonged length of stay exist?

Gallstones are one of the most common morbidities in the world. Laparoscopic cholecystectomy is the gold standard for gallbladder stones’ removal. Few studies focus on the existence of predictive factors aimed at facilitating cholecystectomy in a day surgery setting. The aim of this retrospective study was to identify clinical factors that could guide day-surgery laparoscopic cholecystectomy safety. The study included 985 consecutive patients who underwent elective laparoscopic cholecystectomy for gallstone disease between May 2006 and February 2015. Patients were divided into two groups: group A with a length of stay ≤ 2 days (922 patients); group B with a length of stay > 2 days (63 patients). Univariate analysis showed that age, sex and the presence of obesity, cardiological, and nephrological comorbidities had a higher likelihood of a longer hospital stay. The logistic regression model showed that only age was a significant predictor of a longer stay. No complication has reached the statistical significance of extending the length of stay in group B. Conversely, the presence of such comorbidities has influenced the hospitalization. Our results allow the identification of a category of patients at high risk of hospitalization within 1 or 2 days from treatment. Moreover, we reported that there is no complication specifically affecting the length of stay. Our findings support the idea that a prolonged length of stay is not linked to the surgical procedure but to the patient’s comorbidities.
