The prevalence of diverticular disease in all of its forms has risen among industrialized countries, accounting for 96 of every 100 000 hospital admissions2 in the US in 2008. This represents a considerable source of resource use, with each admission associated with a median length of stay of 4 days and a median treatment cost of $6333.3 While its prevalence continues to rise, there has been a concomitant shift toward a greater proportion of patients with diverticulitis being treated on an outpatient basis, with an associated decline in emergency surgeries and a greater use of minimally invasive approaches in elective settings.4 Past controversies include whether patients should undergo surgery on the basis of young age or a prior paracolic abscess, as well as the role of urgent surgeries that avoid resection, such as laparoscopic lavage.
