Obese appendectomy patients have fewer complications with minimally invasive operations
Date:6/26/2012

09. Approximately 13,330 patients in the database were considered obese, based on a body mass index (BMI) of 30 or higher.

In the first analysis, Mason and his team of surgeons compared how all the obese patients in the database fared after having either an open or laparoscopic appendectomy. Results showed that patients who had the open procedure were significantly more likely to have complications, including wound infections, pneumonia, heart attacks, and septic shock. For example, 8 percent of the open appendectomy patients had non-wound related complications like heart attacks, compared with 4 percent of laparoscopy patients. Additionally, open appendectomy patients stayed in the hospital a mean of 2.3 days longer than patients who had the laparoscopic appendectomy. Overall, the laparoscopic procedure was associated with a 57 percent reduction in morbidity compared with the open procedure in obese patients.

The second analysis matched 1,114 of the laparoscopic appendectomy patients with an open operation patient group who had the same demographics and comorbid conditions. Results again showed that complications were more likely for patients who had open appendectomies. They spent more than a day longer in the hospital, and their procedures took longer than the time required for patients who had the laparoscopic procedure, which was associated with a 53 percent reduction in the risk of morbidity. Also, the more patients weighed, the worse their outcomes were with open procedures. In contrast, all the patients who underwent the laparoscopic procedure had similar outcomes, regardless of how obese they were.

Despite the noted improved outcomes for the laparoscopic surgical approach in patients with complicated appendicitis, over 40 percent of these patients in the database had undergone an open operation. With national expenditures already estimated at about $147 billion for obesity-related conditions,3 the study's r
