Pessaux et al identified risk factors for morbidity and mortality in patients undergoing elective resection of the sigmoid colon for diverticulitis. These can help to identify a patient who may benefit from interventions to reduce the surgical risks. The authors are from multiple hospitals in France.


Since the surgery is elective, risk factors associated with urgent or emergency surgery such as peritonitis are not included.


Risk factors for mortality:

(1) age > 75 years

(2) obesity with body mass index > 30 kg per square meters


Risk factors for intra-abdominal morbidity:

(1) failure to administer effective antibiotic prophylaxis (ceftriaxone preferred) prior to surgery


Risk factors for extra-abdominal morbidity (pneumonia, urinary tract infection, etc):

(1) chronic obstructive pulmonary disease (COPD) with PaO2 < 65 mm Hg

(2) cirrhosis
