Background: Patients suffering from chronic mesenteric ischemia are at risk of malnutrition due to the fear of food and weight loss. However, the impact of malnutrition on the morbidity and mortality at the time of surgery is not studied extensively, just as its prevalence. The main objective of this study was to evaluate the influence of malnutrition on the survival of the patients operated for chronic mesenteric ischemia. The secondary objectives were to evaluate the prevalence of malnutrition in this population and to evaluate the early complications after surgery according to the nutritional condition of the patients.
Methods: We conducted a monocentric retrospective observational study including consecutively all the patients operated for chronic mesenteric ischemia between 2005 and 2016. The nutritional status was determined a posteriori according to the criteria of the French High Health Authority using body mass index, the percentage of weight loss, and albumin. We thus divided the patients into 2 groups, "malnourished" and "non-malnourished." We compared the survival of the patients of the 2 groups with a log-rank test.
Results: We enrolled 54 patients including 35 men (65%), with a mean age of 68.1 years (±12.3). The prevalence of malnutrition was 70% (38 patients), including 9 severely malnourished patients (23.6%). Twenty-nine patients (53.7%) were treated by endovascular technique, and twenty-five had conventional surgery (46.3%). The type of management was not different between the 2 groups: 20 patients of the malnourished group (52.6%) and 9 patients of the non-malnourished group (56.3%) were treated by endovascular technique (P = 0.8). The 30-day mortality was null in the non-malnourished group, whereas ten patients (26.3%) died in the malnourished group (P = 0.02). The short-term complications were not significantly different between the malnourished and the non-malnourished groups (37% vs. 19%, P = 0.32). The mean duration of follow-up was 639 days (±660). The 3-year survival was not different between the endovascular group and the open surgery group (43% vs. 52%, P = 0.7). The 3-year survival was statistically higher in the non-malnourished group (87%) than in the malnourished group (49.6%) (P = 0.01).
Conclusions: In our experience, preoperative malnutrition is a factor significantly decreasing the survival of the patients treated with open surgery or with endovascular technique for chronic mesenteric ischemia. A more optimal preoperative management of this malnutrition could improve the results of these procedures.
