RESUMEN
BACKGROUND: DIEP flap is nowadays considered the gold standard in breast reconstruction. However, venous congestion is still a leading cause of free flap failure. Despite the conspicuous articles regarding the use of a secondary venous anastomosis, there is a lack in the literature regarding the prophylactic use of a secondary venous route to reduce the incidence of complications during breast reconstruction. METHODS: A double-center retrospective study based on women undergoing DIEP breast reconstruction was conducted, dividing patients into case group(DIEP flaps with double venous anastomosis) and control group(DIEP flaps with single venous anastomosis). Demographic and surgical data and complications were compared and statistically analyzed and a reconstructive algorithm was proposed to improve the flap insetting. RESULTS: 154 patients were included in the study, divided into Case group(74 patients) and control group(80 patients). Median age at the time of surgery was 49,09 years (range 29 -68), slightly lower in Group 1 when compared to Group 2. Mean BMI was 25,52 kg/m2(range 21,09-29,37), in particular 25,47 kg/m2 (range 23,44 -28,63) in Group 1 and 25,58 kg/m2(range 21,09-29,37) in Group 2. No statistical differences were found between groups in terms of BMI and smoking and comorbidities history. Average operative times were 272,16 minutes in Group 1 (range 221 - 328) and 272,34 minutes in Group 2(range 221-327), with no significant difference between groups, as well as ischemia times(44,4 minutes in Group 1 (range 38 - 56) and 49,12 minutes in Group 2(range 41- 67). Statistical analysis showed a reduction in short term complications and a statistically significant reduction for take-backs in the comparison of two groups. CONCLUSIONS: Our study suggests that venous supercharging of DIEP flap by performing dual venous anastomosis can be routinely and safely done prophylactically, and thus not only after intraoperative assessment of venous congestion, in order to avoid flap venous congestion and rates of re-exploration.
RESUMEN
This retrospective study examines the implementation of Nexobrid, an enzymatic debriding agent developed from bromelain, for burn debridement in a major Italian burn center. With previous research showing encouraging results for Nexobrid in terms of reducing the need for surgical intervention and faster eschar removal, the current study aims to add to the growing body of evidence regarding its potential benefits and limitations. The patient database was utilized to identify patients who received Nexobrid treatment between October 2019 and June 2023. A retrospective analysis was conducted to gather demographic information, burn causes, procedural details, and patient outcomes. Of the 30 patients treated with Nexobrid, 10% did not require further surgical intervention, showcasing Nexobrid's potential to improve patient outcomes. However, over 80% of patients still required additional surgical intervention, demonstrating that Nexobrid's effectiveness varies across patients and should be considered a tool rather than a definitive solution in burn wound management. A few patients developed complications, and about 10% of patients succumbed to systemic complications. The study results reveal both the potential benefits and limitations of using Nexobrid in burn debridement. While it successfully eliminated the need for further surgical intervention in a small percentage of patients, the majority still required additional surgical procedures. These findings not only highlight Nexobrid's role as a tool in burn wound management but also point toward the discrepancies with previous studies. The authors suggest future research should include randomized controlled trials, direct comparisons between Nexobrid and traditional debridement methods, and studies incorporating larger and more diverse patient groups.
