Surgical Outcomes in 62 Patients with Ulcerative Colitis: A Retrospective, Single-Center Study from Poland

BACKGROUND Surgery continues to play an important role in the treatment of ulcerative colitis (UC), which is one of the most common inflammatory diseases of the colon and rectum. This retrospective study from a single center in Poland aimed to evaluate surgical outcomes in 62 patients with ulcerative colitis. MATERIAL AND METHODS The study enrolled 62 patients (36 men [58.1%], 26 women [41.9%]), mean age 52.69±16.84 (range, 19-96) years who underwent surgical treatment of UC during the period 2001-2020. The mandatory inclusion criteria were patients with UC, who underwent total intra-abdominal colectomy (n=22, 46.8%), proctocolectomy (n=25, 53.2%), or left-sided hemicolectomy (n=8, 12.9%). The primary endpoint was postoperative death, and secondary endpoints were long hospitalization (>15 days), complications, and relaparotomy. RESULTS Postoperative mortality was observed in 8 (12.9%) patients. Older age and low albumin level were associated with longer hospitalization time (P=0.004 and P<0.001, respectively). High C-reactive protein (CRP) level (P=0.003), high CRP/albumin ratio (P=0.023), and malnourishment (P=0.026) were risk factors for complications. Malnutrition (P=0.026), older age (P=0.031), high CRP level (p<0.001), high CRP/albumin ratio (P=0.014), arterial hypertension (P=0.012), and urgent surgeries (P=0.021) were associated with higher risk of postoperative death. Patients who had undergone previous surgeries were more likely to need relaparotomy (P=0.022). CONCLUSIONS Preoperative nutritional status was an important factor associated with postoperative outcomes in patients with ulcerative colitis. Correction of malnutrition seems to be a vital part of preoperative preparation.
