Impact of Socioeconomic and Territorial Inequalities on Surgical Management of Sigmoid Diverticulitis

Sigmoid diverticulitis (SD) is a common pathology characterized by inflammation/infection of a diverticulum in the sigmoid colon. Surgical treatment of DS is indicated urgently, either because of a serious complication or because of therapeutic failure. Prophylactic surgical treatment of \"cold\" DS is indicated in symptomatic forms (smoldering diverticulitis, frequent recurrences impacting quality of life, symptomatic fistula, and stenosis). It is also indicated for asymptomatic forms in selected patients, to avoid recurrence and/or the occurrence of a DS complication. In France, some 12,000 prophylactic colectomies for DS are performed every year. The mortality rate for this operation during the hospital stay (which does not account for 30-day mortality) is 7 per thousand in France. Morbidity is fairly high, at around 25%, with almost 10% of severe complications. At a distance, the definitive stoma rate is around 6% of patients, and recurrences have been described in up to 10% of cases. Numerous clinical determinants linked to the patient and the pathology have been identified as potential risk factors for morbidity and mortality (advanced age, undernutrition, emergency surgery, neurological history, minimally invasive approach, etc.). Among non-clinical determinants, socio-economic and territorial deprivation is thought to have an impact on postoperative morbidity and mortality for a very large number of pathologies, including cardiovascular disease, cancer, and obesity. Thus, patients from the most disadvantaged backgrounds would have a significantly higher risk of postoperative mortality and morbidity. To our knowledge, however, few data are available on the possible impact of socio-economic deprivation and geographical isolation on the operative outcome of colorectal surgery. This French multicenter study aims to assess the impact of socio-economic and territorial inequalities on the surgical management of sigmoid diverticulitis; with the primary objec
