Chronic Pain, Quality of Life, and Functional Impairment After Surgery Due to Small Bowel Obstruction

Abstract

BACKGROUND: Emergency laparotomy is a high-risk procedure regarding short-term outcomes; however, long-term outcomes are not well described. The aim of this study was to determine the frequency of chronic postoperative pain, pain-related functional impairment, and incisional hernias and to evaluate the gastrointestinal quality of life after emergency laparotomy due to small bowel obstruction. METHODS: This study was a questionnaire study, conducted at a major gastrointestinal-surgery department in a single tertiary university hospital in Denmark. Patients who had been through emergency laparotomy due to small bowel obstruction were included in the study. The extent of acute and chronic postoperative pain and the prevalence of incisional hernias were examined with specially designed questionnaires, while the pain quality was assed by the self-report version of the S-LANSS-questionnaire. Pain-related functional impairment and quality of life were measured using the AAS and the GIQLI questionnaire, respectively. RESULTS: A total of 90 patients returned the questionnaire (response rate 82 %). Nineteen patients (21 %) suffered from chronic postoperative pain. Seventeen patients (19 %) had pain-related functional impairment as a result of the surgery, and 17 patients (19 %) had an incisional hernia at follow-up. Patients with chronic postoperative pain had significantly lower gastrointestinal quality of life score compared with the remaining study population (109 (IQR 39) vs. 127 (IQR 19), P < 0.001). CONCLUSIONS: Chronic postoperative pain is a common long-term complication after emergency laparotomy, and it is related to decreased quality of life. These results should be confirmed in prospective studies.
