RESUMO
BACKGROUND: As the population ages emergency surgeries among the elderly population, including colonic resections, is also increasing. Data regarding the short- and long-term outcomes in this population is scarce. METHODS: A retrospective study was performed to investigate mortality and mortality risk factors associated with emergent colectomies in older compared to younger patients in a single university affiliated tertiary hospital. Patients with metastatic disease, colectomy due to trauma or index colectomy within 30 days prior to emergent surgery were excluded. RESULTS: Operative outcomes compared among age groups, included 30-day mortality, mortality risk-factors and long-term survival. 613 eligible patients were included in the cohort. Mean age was 69.4 years, 45.1% were female. Patients were divided into four age groups: 18-59, 60-69, 70-79 and ≥80-years. Thirty-day mortality rates were 3.2%, 11%, 29.3% and 37.8%, respectively and 22% for the entire cohort. Risk-factors for perioperative death in the younger group were related to severity of ASA score and WBC count. In groups 60-69, 70-79, main risk-factors were ADL dependency and ASA score. In the ≥80 group, risk-factors affecting perioperative mortality, included ASA score, pre-operative albumin, creatinine, WBC levels, cancer etiology, ADL dependency, and dementia. Long-term survival differed significantly between age groups. CONCLUSION: Perioperative mortality with emergency colectomy increases with patients' age. Patients older than eighty-years undergoing urgent colectomies have extremely high mortality rates, leading to a huge burden on medical services. Evaluating risk-factors for mortality and pre-operative discussion with patients and families is important. Screening the elderly population for colonic pathologies can result in early diagnosis potentially leading to elective surgeries with decreased mortality.
RESUMO
BACKGROUND: While left-sided colonic diverticular disease is common in Western Caucasian populations, right-sided colonic disease (RCD) is rare. The present study aimed to determine the rate of RCD and to identify the symptoms, clinical features, treatment, and outcomes in a single medical center in Israel. METHODS: Data for this descriptive retrospective analysis were collected from the electronic medical records of all patients diagnosed with colonic diverticulitis from January 2014 to June 2019. RESULTS: During the study period, 1000 patients with diverticulitis were admitted to our institution, of which 99 had RCD (10%). Mean age was 50.2 years. The main presenting symptom was acute onset of right-sided abdominal pain. The diagnosis was made almost exclusively by computed tomography scan and the cecum was the most frequent site. The clinical course was benign, without major complications for most patients (90.1%). Nine patients presented with abscess (n = 1), covered perforation (n = 7), or partial obstruction (n = 1). All patients were treated with intravenous antibiotics with a median length of hospital stay of 3 days and a median 9 days of antibiotic treatment. Only 1 patient underwent diagnostic laparoscopy due to suspected intestinal perforation. Three patients experienced disease recurrence after a median follow-up of 48 months. Upon recovery, half of the patients underwent colonoscopy; no further pathology was found in any. CONCLUSION: Unlike sigmoid colon diverticulitis, the incidence of RCD in Western populations is low. The clinical course is benign, with conservative treatment without the need for surgery. The complication and recurrence rates are low.
