Abstract
STUDY AIM
Manual circular staplers are widely used in colorectal surgery; however, limited literature exists examining complications related to circular anastomoses when such devices are used. The present study evaluated the incidence, predictors, and economic burden of circular anastomotic complications in left-sided colorectal reconstructions involving manual circular staplers.
MATERIALS AND METHODS
Patients aged ≥18 years who underwent hemicolectomy, low anterior resection, or sigmoidectomy between 1 October 2016 and 31 December 2018 were identified from the Premier Healthcare Database. Manual circular stapler use was identified from hospital administrative billing records. Circular anastomotic complications were defined as a composite endpoint of multiple circular stapler use (proxy for stapler failure) or other circular anastomotic complications (anastomotic leak, bleeding, device/surgical complications, infection, and transfusion). Multivariable analyses were used to model the associations between circular anastomotic complications and total hospital costs, length of stay, operating room time, and 30-, 60-, and 90-day readmission rates.
RESULTS
A total of 13,167 patients met the study criteria, of whom 2,984 (22.7%) had circular anastomotic complications. Predictors of circular anastomotic complications included age, procedure type, provider region, and select patient comorbidities. As compared with those who did not, patients who suffered circular anastomotic complications had significantly higher adjusted total hospital costs ($26,924 vs. $18,748; p < .0001), length of stay (7.79 vs. 4.99 days; p < .0001), operating room time (280 vs. 239 min; p < .0001), non-home discharge status (9.63% vs. 4.61%; p < .0001), and all-cause readmission at 30 days (12.2% vs. 8.7%; p < .0001), 60 days (16.0% vs. 11.6%; p < .0001), and 90 days (18.5% vs. 13.4%; p < .0001).
LIMITATIONS
The present study is limited by the observational nature and potential for measurement error that is inherent to administrative healthcare databases.
CONCLUSIONS
In this analysis of patients undergoing left-sided colorectal reconstructions involving a manual circular stapler, circular anastomotic complications were associated with adverse economic consequences.
