Background  

Laparoscopic cholecystectomy in elderly patients has been linked to higher complication rates and longer lengths of stay. The purpose of this study was to identify risk factors associated with prolonged postoperative hospitalization in elderly patients undergoing laparoscopic cholecystectomy.

Methods  

The records of 287 patients aged 65 years or older, who underwent successful laparoscopic cholecystectomy between January 2001 and July 2006, were retrospectively reviewed. Clinical data was abstracted from the chart and compared between patients with a shorter or longer postoperative stay.

Results  

The median postoperative hospital stay was three days (interquartile range 3–5). Forty-eight patients had complications, with an overall morbidity of 16% and mortality of 0.7%. The only independent predictor of prolonged postoperative stay was the occurrence of any major complication [odds ratio, 3.144; 95% confidence interval (CI), 1.882–5.251]. The physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and underlying chronic obstructive pulmonary disease were independently associated with major complications.

Conclusions  

A major complication is the most important cause of prolonged hospital stay after laparoscopic cholecystectomy in the elderly. No specific comorbidity has direct impact on the duration of hospitalization, but pulmonary disease is associated with increased risk of major complications.
