Abstract
INTRODUCTION Studies identifying predictors of postoperative outcomes in adhesive small bowel obstruction are limited. This study investigates the efficacy of the modified frailty index (mFI)to predict postoperative morbidity and mortality among patients undergoing surgery for adhesive small bowel obstruction. METHODS A multicentre retrospective cohort study including patients undergoing surgery for adhesive small bowel obstruction after failed trial of nonoperative management between January 2015 and December 2020 was performed. Impact of frailty status using the mFI, stratified as frail (≥0.27) and robust (<0.27), on postoperative morbidity, mortality, length of stay, and discharge destination was evaluated using multiple logistic regression. RESULTS Ninety-two robust patients (mean age 62.4 y, 68% female) and 41 frail patients (mean age 81.7 y, 63% female) were included. On simple stratification, frail patients had significantly increased 30-d morbidity (overall morbidity 80% versus 49%) and need for higher level of care on discharge (41% versus 9%). However, on multiple regression, functional dependence but not the mFI, was independently associated with worse 30-d overall morbidity (odds ratio [OR] 3.97, confidence interval [CI] 1.29-12.19) and lower likelihood of returning to preoperative disposition (OR 0.21, CI 0.05-0.91). The delay in operation beyond 5 d was independently associated with worse 30-d outcomes including overall morbidity and mortality (OR 7.54, CI 2.13-26.73) and decreased return to preoperative disposition (OR 0.14, CI 0.04-0.56). CONCLUSIONS The mFI, although promising, was not independently predictive of outcomes following surgery for adhesive small bowel obstruction. Further adequately powered studies are required.

Modified frailty index predicts postoperative morbidity in adhesive small bowel obstruction: analyzing the National Inpatient Sample 2015-2019. J Gastrointest Surg 2024; 28:205-214. [PMID: 38445910 DOI: 10.1016/j.gassur.2023.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Revised: 10/08/2023] [Accepted: 10/25/2023] [Indexed: 03/07/2024]
Abstract
BACKGROUND There are limited data identifying predictors of postoperative outcomes in adhesive small bowel obstruction (ASBO). This study used the National Inpatient Sample (NIS) to assess the efficacy of the modified frailty index (mFI) to predict postoperative morbidity among patients undergoing an operation for ASBO. METHODS A retrospective analysis of the NIS between September 1, 2015, and December 31, 2019, was performed to identify adult patients who underwent nonelective operative intervention for ASBO. The mFI was used to stratify patients as either frail (mFI value ≥ 0.27) or robust (mFI value < 0.27). The primary outcomes were overall in-hospital postoperative morbidity and mortality. The secondary outcomes were system-specific morbidity, length of stay (LOS), total in-hospital healthcare cost, and discharge disposition. Univariable and multivariable regressions were used. RESULTS Overall, 23251 robust patients and 6122 frail patients were included. Adjusted analyses demonstrated that frail patients had increased in-hospital mortality (adjusted odds ratio [aOR], 2.16; 95% CI, 1.80-2.60), postoperative morbidity (aOR, 1.63; 95% CI, 1.52-1.74), postoperative LOS (adjusted mean difference [aMD], 0.97 days; 95% CI, 0.73-1.21), and total in-hospital healthcare costs (aMD, $18,921; 95% CI, $14,608-$23,235) and were less likely to be discharged home (aOR, 0.59; 95% CI, 0.55-0.63). The findings were unchanged on subgroup analysis of patients undergoing open operation and those older than 65 years of age. CONCLUSION The mFI may predict postoperative outcomes for ASBO. Stratifying patients based on frailty may assist clinicians and patients in making informed decisions, setting realistic expectations, and proactively planning postoperative disposition.

Complicated Abdominal Wall Hernias in the Elderly: Time Is Life and Comorbidities Matter. Am Surg 2022:31348221101577. [PMID: 35578773 DOI: 10.1177/00031348221101577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
BACKGROUND Abdominal wall hernias represent a common problem that can present as surgical emergencies with increased morbidity and mortality. The data examining outcomes in elderly patients with hernia emergencies is scant. METHODS The 2007-2017 ACS-NSQIP database was queried. Patients ≥65 years old with a diagnosis of acute complicated abdominal wall hernia were included. Univariable and multivariable analyses were used to identify independent predictors of 30-day mortality and surgical site infection (SSI). RESULTS Main predictors of 30-day mortality were admission from nursing home or chronic care facility (OR = 1.62, 95% CI: 1.10-2.38, P = .014), transfer from outside ED (OR = 1.81, 95% CI: 1.31-2.51, P < .001), days from admission to operation (OR = 1.05, 95% CI: 1.02-1.08, P = .002), recent significant weight loss (OR = 1.95, 95% CI: 1.12-3.37, P = .018), pre-operative septic shock (OR = 4.13, 95% CI: 2.44-6.99, P < .001), ventilator dependence (OR = 2.50, 95% CI: 1.29-4.81, P = .006), and ASA status. When compared to open repair, laparoscopic repair emerged as protective against SSI (OR = .34, 95% CI: .17-.66, P = .001). Bowel resection (OR = 2.15, 95% CI: 1.63-2.84, P < .001) and increasing wound class were risk factors for SSI. CONCLUSION In the elderly patient presenting with an acute complicated abdominal wall hernia, time to surgery is crucial for survival, and comorbidities influence outcome. Laparoscopy is an option in management due to its decreased risk of surgical site infection without increased mortality, whenever patient factors are favorable for this approach.
