Abstract

BACKGROUND: Sigmoid volvulus, a gastrointestinal disorder characterized by twisted bowel, often requires medical intervention, either through endoscopic or surgical means, to avoid potentially severe outcomes. This study examined the challenges elderly patients face in undergoing surgical treatment, encompassing both mortality and morbidity. Furthermore, it aimed to determine how medical practices and outcomes have changed over a period of 17 years.

METHODS: We utilized data from the National Surgical Quality Improvement Project, which covers the period from 2005 to 2021, to identify patients who underwent left hemicolectomy for colonic volvulus. The patients were categorized into three age groups: < 60 years, 60-75 years, and > 75 years. We performed a meticulous logistic regression analysis, carefully adjusted for risk factors, to compare mortality, morbidity, and types of surgical treatment administered among the different age groups.

RESULTS: Our study included 6775 patients. The breakdown of the patient population was as follows: 2067 patients were < 60 years of age, 2239 were between 60 and 75 years of age, and 2469 were > 75 years of age. The elderly cohort, those aged above 75 years, were predominantly male, had lower BMIs, underwent fewer laparoscopic surgeries, required more diverting stomas and end-ostomies, and had longer hospital stays. Notably, the elderly population faced a mortality risk that was 5.67 times (95% CI 3.64, 9.20) greater than that of their youngest counterparts, with this risk increasing by 10% (95% CI 1.06, 1.14) for each additional year of age. Furthermore, the odds of mortality associated with emergency surgery were 1.63 times (95% CI 1.21, 2.22) higher than those associated with elective surgery. The postoperative morbidity odds were also elevated for emergency surgeries, 1.30 times (95% CI 1.08, 1.58) greater than that for elective cases. Over the 17-year period, we observed a decline in mortality rates, an increase in the utilization of laparoscopic procedures, and overall stability of morbidity rates.

CONCLUSION: Our findings highlight the increased vulnerability of patients over 75 years of age, who are not only at an elevated risk of mortality compared to their younger counterparts, but also a continuously increasing risk with age. By focusing on elective surgeries for younger patients and minimizing emergency surgeries for the elderly, it may be possible to reduce the mortality risk associated with surgical interventions in this population.
