Abstract

Background Successful intraoperative microvascular anastomoses are essential for deep inferior epigastric perforator (DIEP) flap survival. This study identifies factors associated with anastomotic failure during DIEP flap reconstruction and analyzes the impact of these anastomotic failures on postoperative patient outcomes and surgical costs. Methods A retrospective cohort study was conducted of patients undergoing DIEP flap reconstruction at two high-volume tertiary care centers from January 2017 to December 2020. Patient demographics, intraoperative management, anastomotic technique, and postoperative outcomes were collected. Data were analyzed using Student's t -tests, Chi-square analysis, and multivariate logistic regression. Results Of the 270 patients included in our study (mean age 52, majority Caucasian [74.5%]), intraoperative anastomotic failure occurred in 26 (9.6%) patients. Increased number of circulating nurses increased risk of anastomotic failure (odds ratio [OR] 1.02, 95% confidence Interval [CI] 1.00–1.03, p <0.05). Presence of a junior resident also increased risk of anastomotic failure (OR 2.42, 95% CI 1.01–6.34, p <0.05). Increased surgeon years in practice was associated with decreased failures (OR 0.12, CI 0.02–0.60, p <0.05). Intraoperative anastomotic failure increased the odds of postoperative hematoma (OR 8.85, CI 1.35–59.1, p <0.05) and was associated with longer operating room times (bilateral DIEP: 2.25 hours longer, p <0.05), longer hospital stays (2.2 days longer, p <0.05), and higher total operating room cost ($28,529.50 vs. $37,272.80, p <0.05). Conclusion Intraoperative anastomotic failures during DIEP flap reconstruction are associated with longer, more expensive cases and increased rates of postoperative complications. Presence of increased numbers of circulators and junior residents was associated with increased risk of anastomotic failure. Future research is necessary to develop practice guidelines for optimizing patient and surgical factors for intraoperative anastomotic success. [ABSTRACT FROM AUTHOR]

Abstract

Nutritional rickets resulting from calcium insufficiency is common in Nigeria and high dietary phytate is thought to inhibit calcium and zinc absorption. We compared the effects of a high-phytate meal and enzymatic dephytinization on calcium and zinc absorption in Nigerian children with and without rickets. Nineteen children with rickets and 15 age-matched control children, aged 2-10 y, were given calcium (600 mg/d) and ergocalciferol (1250 [micro]g/wk). After 6 wk, calcium and zinc absorption were measured in both groups with and without maize porridge using stable isotopes. One week later, absorption measurements were repeated to assess the effects of enzymatic dephytinization and fermentation of the maize porridge. The phytate concentration of maize porridge (3.87 [+ or -] 0.38 g/kg wet weight) was reduced by enzymatic dephytinization (2.83 [+ or -] 0.41 g/kg; P < 0.001) but not by fermentation (3.35 [+ or -] 0.27 g/kg; P = 0.08). Calcium and zinc absorption were unaffected by the presence of rickets or by fermentation of maize porridge. Calcium absorption was greater.with a meal (61.3 [+ or -] 25.1%) than without (27.8 [+ or -] 14.6%; P < 0.001). Zinc absorption was lower with a meal (16.2 [+ or -] 8.0%) than without (63.4 [+ or -] 23.9%; P < 0.001). Enzymatic dephytinization increased relative zinc absorption from a meal by 101 [+ or -] 81% (P < 0.001) but did not affect calcium absorption. Rickets was not associated with impaired calcium or zinc absorption. Calcium absorption was enhanced by maize porridge, but zinc absorption was reduced. Enzymatic dephytinization increased zinc absorption. Multiple strategies may be required to optimize calcium and zinc absorption in deficient populations.
