Positive effects of the enhanced recovery after surgery (ERAS) protocol in DIEP flap breast reconstruction

Global perspectives on practices and preferences in autologous free flap breast reconstruction: From flap selection to postoperative care A descriptive quantitative study

Background

The purpose of this study was to evaluate the present-day practices in the preparation, peri-, and postoperative care for patients undergoing autologous free flap breast reconstructions (ABR) worldwide, with the aim of enhancing informed decision-making for plastic surgeons during the planning stages of ABR.

Methods

A global survey was conducted among 280 plastic surgeons and 39 plastic and reconstructive surgery societies worldwide, enquiring about flap and donor site selection, surgical actions, perforator imaging, and perioperative care during ABR.

Results

Eighty-two responses were received, among which 71% (n=58) were completed questionnaires. The preferred flap of choice was the deep inferior epigastric perforator flap (85%, n=51), with the internal mammary artery as the most commonly used recipient vessel. Preoperative imaging for ABR was typically performed using computed tomography angiography (75%, n=44) and often combined with a handheld Doppler. Handheld Doppler was the most frequently used modality to localize perforator vessels during surgery (33%, n=19), with the majority using either one (47%, n=24) or two (51%, n=26) perforators intraoperatively. These preferences were consistent across all clinic types.Postoperatively, flap monitoring was primarily performed by the nursing staff, initially every hour on the first day and at reduced frequencies on subsequent days.The most commonly used modality for monitoring flap viability was the handheld Doppler. The average length of hospital stay was 5 days.

Conclusion

This study provides valuable insights into the current preparations and peri- and postoperative care in ABR procedures worldwide, aiding in the development of standardized practices and potentially improving patient outcomes.

How low can we go: Achieving postoperative day 1 discharge after deep inferior epigastric perforator, a safe and feasible goal

BACKGROUND

Although rare reports describe discharge to be possible within 48 hours for patients undergoing autologous breast reconstruction, average length of stay remains around 3 days. This study aimed to demonstrate that patients can be safely discharged within 1 day after deep inferior epigastric perforator (DIEP) flap breast reconstruction.

METHODS

A retrospective review was performed of patients who underwent free flap breast reconstruction by a single surgeon from November 2021 to May 2024. Demographics, operative details, opioid ingestion, length of stay, and postoperative complications were reviewed to assess safety of discharge in 24 hours.

RESULTS

One hundred sixty-four DIEP flaps were performed on 119 patients. Average length of stay was 1.5 days (SD 0.7 days), with 67 (56.3%) patients discharged on postoperative day 1 (POD1) and 52 (43.7%) discharged after POD1. Of those discharged on POD1, 13 (19.4%) went home in <24 hours. Comparing patients discharged on POD1 to those discharged after POD1, there were statistically significant differences in reconstruction laterality (76.1% vs 44.2% unilateral, p<0.001), operative time (341.0 vs 439.1 minutes, p<0.001), and opioid ingestion on POD1 (4.2 IV morphine milligram equivalents [MME] vs 11.3 MME, p<0.001). Common complications included abdominal wound dehiscence (10.1%), abdominal seroma (5.0%), breast wound dehiscence (4.9%), and breast mastectomy flap necrosis (3.0%). Seventy-six (63.9%) patients had no complications. Overall success rate of flap reconstruction was 100%.

CONCLUSION

Collaboration among surgery, anesthesia, and dedicated nursing teams allow 23-hour observation or outpatient DIEP reconstruction to be safe and feasible. By attaining equivalency with implant-based reconstruction, access to flap reconstruction can be extended to more patients.

Reduced length of stay and less systemic complications, implementation of the optimized DIEP recovery pathway

BACKGROUND AND AIMS

The present study aimed to compare patients who underwent deep inferior epigastric perforator (DIEP) flap reconstruction with and without the implementation of the new optimized surgical recovery pathway. The new protocol aims to standardize and optimize perioperative management, shorten hospital stays, and lower complication rates for patients undergoing major surgical procedures.

METHODS

Consecutive patients who underwent immediate or delayed DIEP flap breast reconstruction were included in this study. Data regarding patient demographics, timing, laterality of reconstruction, hospital length of stay (LOS), and drain management were collected and compared for the pre-protocol group and the post-protocol group.

RESULTS

The pre-protocol group consisted of 65 patients, while the post-protocol group consisted of 68 patients. The two groups had similar total complication rates (pre-protocol 43.1% versus post-protocol 32.4%, p = 0.20). Between the two groups, there was a significantly lower rate of major surgical complications in the post-protocol group (pre-protocol 32.3% versus post-protocol 14.7%, p = 0.016). There were no significant differences between the groups regarding minor surgical complications (pre-protocol 7.7% versus post-protocol 17.6%, p = 0.086). In the pre-protocol group, the mean LOS was 6.1 days (range = 4-10, median = 6); in the post-protocol group, the mean LOS was 3.6 days (range = 3-10, median = 3; p < 0.00001). Majority of the post-protocol patients were discharged on postoperative day 3 (n = 47, 69.1%).

CONCLUSION

Patients undergoing DIEP flap reconstruction can be discharged earlier without risking their safety by following the new protocol.

Quality of plastic surgery Enhanced Recovery After Surgery (ERAS) studies: A systematic review

BACKGROUND

In effort to improve post-operative outcomes, enhanced recovery after surgery (ERAS) protocols have gained popularity. The objective of this systematic review was to assess the reporting and methodological quality of plastic surgery ERAS studies.

METHODS

All plastic surgery ERAS implementation studies, published between January 1, 2020, to November 20, 2023, were included. The primary outcome was reporting quality based on "The Reporting on ERAS Compliance, Outcomes, and Elements Research (RECOvER) checklist" (40 points). Secondary outcomes included methodology quality as per ERAS® Society endorsed guidelines (Breast 18 points; Head and Neck (H&N) 24 points).

RESULTS

Fifty ERAS studies were included (breast reconstruction: 29, 58%; head and neck: 7, 14%; craniofacial: 6, 12%; aesthetic: 5, 10%; other: 3, 6%). Average reporting quality was 22.6/40 (56.7%). ERAS protocol elements least adhered to included: patient warming strategy (8/50, 16%), management of post-operative fluids (14/50, 28%), and post-discharge outcome tracking (14/50, 28%). Evaluation of breast methodological quality revealed average compliance of 9.2/18 (51.3%). The least complied with elements included preoperative computed tomography angiography (4/23, 17.4%), intraoperative warming (6/23, 26.1%), and post-operative wound management (2/23, 8.7%). For head and neck studies, average compliance was 9.1/23 (39.6%). The least complied with elements included pre-anesthesia pain medications (1/7, 14.3%), post-operative wound care (0/7, 0%), and urinary catheterization removal (1/7, 14.3%).

CONCLUSIONS

ERAS implementation studies in plastic surgery are highly variable, with overall low reporting and methodology quality. Plastic surgeons should be cautious when adopting published ERAS protocols that do not adhere to the recommended and official ERAS® Society guidelines.

Effect of Enhanced Recovery after Surgery in Morbidly Obese Patients Undergoing Free Flap Breast Reconstruction

BACKGROUND

 Enhanced recovery after surgery (ERAS) pathways have been widely implemented across many surgical practices, including autologous breast reconstruction. However, the benefits of ERAS in the morbidly obese population have yet to be defined.

METHODS

 A retrospective chart review of patients undergoing deep inferior epigastric artery perforator (DIEP) flap breast reconstruction at our institution from 2017 to 2022 was performed. Length of stay (LOS), intensive care unit (ICU) utilization, opioid usage, cost, and flap outcomes were analyzed in patients with body mass index greater than 35 before and after ERAS implementation.

RESULTS

 Thirty-five morbidly obese patients receiving DIEP flap breast reconstruction were identified before ERAS and 18 after ERAS. There were no differences in unilateral versus bilateral or immediate versus delayed reconstruction. LOS decreased with ERAS (3.43 vs. 2.06 days, p < 0.0000001). ICU utilization decreased with ERAS (0.94 vs. 0.0 days, p < 0.0001). Daily and total opioid usage decreased with ERAS (41.8 vs. 17.9 morphine milligram equivalent [MME], p < 0.0001; 190.5 vs. 54.7 MME, p < 0.0001). Financial metrics improved with ERAS, including decreased total cost ($33,454 vs. $25,079, p = 0.0002) and increased cost margin ($4,458 vs. -$8,306, p = 0.004). There were no differences in donor or recipient site outcomes including flap loss, deep venous thrombosis/pulmonary embolism, hernia/bulge, delayed wound healing, revisions, and blood loss.

CONCLUSION

 ERAS pathways maintain benefits in the morbidly obese population undergoing abdominally based autologous breast reconstruction, including decreased LOS, ICU utilization, opioid use, and cost while maintaining successful reconstruction outcomes.

Assessing Donor Site Morbidity and Impact on Quality of Life in Free Flap Microsurgery: An Overview

Donor site morbidity remains a significant concern in free flap microsurgery, with implications that extend beyond immediate postoperative outcomes to affect patients' long-term quality of life. This review explores the multi-faceted impact of donor site morbidity on physical, psychological, social, and occupational well-being, synthesizing findings from the existing literature. Particular attention is given to the functional limitations, sensory deficits, aesthetic outcomes, and chronic pain associated with commonly utilized free flaps. Advancements in surgical techniques, including nerve-sparing and muscle-sparing methods, as well as innovations, like perforator flaps, have demonstrated the potential to mitigate these morbidities. Furthermore, the integration of regenerative medicine strategies, such as stem cell therapy and fat grafting, and technological innovations, including virtual reality rehabilitation and biofeedback devices, has shown promise in enhancing recovery and minimizing long-term complications. Despite these advances, challenges persist in standardizing QoL assessments and optimizing donor site management. This review emphasizes the need for a holistic, patient-centered approach in reconstructive microsurgery, advocating for further research to refine current strategies, improve long-term outcomes, and develop robust tools for QoL evaluation. By addressing these gaps, reconstructive surgeons can better align surgical objectives with the comprehensive well-being of their patients.

Meta analysis of 2059 patients assessing early discharge after DIEP flap breast reconstruction: Comprehensive outcomes before post-operative day 5

Autologous reconstruction with DIEP flap has illustrated greater patient satisfaction with both aesthetic satisfaction and reconstructive treatment process when compared to implant-based reconstruction longitudinally. However, DIEP flap breast reconstruction is associated with longer in-patient hospitalizations to monitor flap status. This systematic review and meta-analysis aims to report outcomes regarding the use of enhanced recovery after surgery (ERAS) protocols, particularly looking at the impact on complication rates in patients who undergo DIEP flap procedures and are discharged within 5 days after surgery. A computerized search was conducted on September 29th, 2023 using the MeSH terms "Free Tissue Flaps" OR "Myocutaneous Flap" OR "Surgical Flaps" AND "Patient Discharge". Twenty-four papers reporting on 2059 patients were included in the study, and four study groups were created by length of stay as follows: LOS 1-1.99 days = Group 1, LOS 2-2.99 days = Group 2, LOS 3-3.99 = Group 3, and LOS 4-5 days = Group 4 (control). An independent samples t-test was performed to compare the mean rates of each complication between Groups 1 and 4, Groups 2 and 4, and Groups 3 and 4. This meta-analysis showed no significant differences between rates of hematoma, seroma, infection and reoperation between groups. There was a significantly lower rate of total flap loss in all 3 groups with LOS less than 4 days when compared to the group with LOS between 4 and 5 days. This meta-analysis shows that appropriate patients may be discharged safely as early as POD1 following DIEP flap.

Transforming care: Optimizing ERAS pathway in breast cancer surgery with latissimus dorsi flap

INTRODUCTION

This study aims to establish, execute, and assess the effectiveness of a perioperative enhanced recovery after surgery (ERAS) clinical care pathway in breast reconstruction patients with LD flap breast cancer treatment. The goal is to improve early recovery outcomes, reduce hospitalization time, and enhance patient satisfaction by implementing a standardized approach to postoperative care.

METHODS

This study was conducted at the University of Malaya Medical Center. The outcomes of 21 breast cancer patients who underwent autologous reconstructive breast surgery with the latissimus dorsi (LD) flap within six months before the implementation of the ERAS pathway (pre-ERAS) were compared with 26 patients who underwent the same surgery with the ultrasound-guided erector spinae plane (ESP) block for the (ERAS protocol implementation) cohort. The study was conducted from November 2019 to October 2020. The length of hospital stay, amount of analgesic usage, and incidence of postoperative nausea vomiting (PONV) were recorded.

RESULTS

The implementation of the ERAS clinical care pathway resulted in shorter hospital stays compared with the preceding care. On average, ERAS patients were mostly discharged on Day 2 post-surgery, whereas pre-ERAS patients were mostly discharged on Day 7. ERAS patients had a lower incidence of PONV from Days 1 to 5, starting with 88.5% not experiencing the condition on Days 1 and 2 and increasing to 100% on Day 5. All pre-ERAS patients experienced PONV in the first 5 days post-surgery. Fewer ERAS patients required antiemetics post-surgery (88.5%) compared with pre-ERAS patients (42.9%).

CONCLUSION

The implementation of the ERAS protocol as part of clinical care in autologous reconstructive breast surgery with the LD flap can improve recovery by shortening hospital stay, decreasing the use of analgesia, and alleviating PONV.

Sustainability in Reconstructive Breast Surgery: An Eco-audit of the Deep Inferior Epigastric Perforator Flap Pathway

Background

The deep inferior epigastric perforator (DIEP) flap provides an effective and popular means for autologous breast reconstruction. However, with the complexity of the pathway, the environmental impact of the pathway has yet to be evaluated.

Methods

A retrospective analysis of 42 unilateral DIEPs at a single reconstructive center was performed. Process mapping and life-cycle analyses were performed for equipment, staff, patients, and land. A bottom-up approach was adopted to calculate carbon dioxide equivalent estimates for the initial consultation, preoperative, intraoperative, and immediate postoperative periods.

Results

This study estimated the carbon footprint of a patient undergoing DIEP flap surgery to be approximately 233.96 kg CO2eq. Induction, maintenance, and running of anesthesia had the highest overall contribution to the carbon footprint (158.17 kg CO2eq, 67.60% overall). Patient and staff travel contributed more than 15% overall carbon emissions in this study. The impact of sterilization was less than half of that from waste management (0.81 versus 1.81 kg CO2eq, respectively). Waste management alone contributed 4.21 kg CO2eq of the overall carbon emissions, the majority of which was accountable to the incineration of 14.75 kg of noninfectious offensive waste.

Conclusions

This study estimates the carbon footprint of the DIEP pathway. Strategies to mitigate the impact of carbon emissions including usage of reusable vs single-use equipment, virtual consultations, standardization of equipment packs, and optimizing waste disposal were suggested areas for improvement. Data from manufacturers on life-cycle assessments were limited, and further work is needed to fully understand and optimize the impact of DIEP surgery on the environment.

How to increase the success rate in microsurgical free and pedicled flap reconstructions with intraoperative multistep ICG imaging: A case series with 400 consecutive cases

BACKGROUND

Over the last decade, microsurgical soft-tissue transfer became the gold standard for various reconstructions throughout the body. Continuous improvement of instruments and surgical techniques, such as intraoperative indocyanine green angiography (ICG-A), allowed for a very high success rate. This study aimed to assess and validate the role of a standard intraoperative ICG-A in free and pedicled flap surgery to improve overall outcomes.

PATIENTS AND METHODS

From April 2018 to April 2023, 400 consecutive patients who underwent reconstruction using free and pedicled flaps were enrolled. ICG-A was always performed in a free flap after flap elevation, after microsurgical anastomosis, immediately after the flap inset, and after wound closure. In the pedicled flap, the sequential procedure was performed after flap elevation, flap inset, and wound closure.

RESULTS

All 400 patients who underwent flap reconstruction using intraoperative ICG-A had an extremely low incidence of necrosis (0.75% partial necrosis among free and pedicled flaps) and reoperation for perfusion-related complications (0.75% due to acute ischemia and 0.50% due to flap congestion). Minor complications, such as hematoma, seroma, wound dehiscence, and wound infections, were managed with a second operation. No flaps were lost, and all patients were successfully treated.

CONCLUSIONS

This study showed how systematic multistep ICG-A for intraoperative assessment of free and pedicled flap perfusion can significantly reduce the complication rate, including flap loss and re-exploration surgeries, in a time- and cost-effective manner.

Shifting toward total drainless approach in DIEP flap-based breast reconstruction: Evaluation of safety

With increasing interest in swift postoperative recovery, there has been a trend toward omitting drains in deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, ideally aiming to avoid drains in the breasts and abdomen. This study evaluated our transition toward total drainless reconstruction, focusing specifically on the safety of omitting drains in the breasts. Patients who underwent breast reconstruction with DIEP flap from 2018 to 2023 were reviewed. They were divided into 3 groups: group A (with drains in the abdomen and breast), group B (drains only in the breast), and group C (total drainless). For group C, routine ultrasound examinations were performed to check for fluid accumulation. Complication profiles were compared among the groups. In total, 294 cases were included, comprising 77 in group A, 112 in group B, and 105 in group C. Chronologically, a gradual increase in the proportion of cases in group C was observed, with the complication rates remaining stable. On comparing the complication profiles of the recipient and donor sites among the 3 groups, no significant differences were found. Breast seroma, persisting 1 month postoperatively, was exclusively detected in 6 (5.7%) cases within group C, all of whom were treated with outpatient clinic-based aspiration. When restricting the analysis to group C, a greater weight of mastectomy specimen and axillary lymph node dissections exhibited an independent association with breast seroma development. Smooth transition to total drainless DIEP breast reconstruction appears safe, without significantly increasing the risks of complication.

Liposomal Bupivacaine Analgesia in Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Retrospective Cohort Study

Background

Liposomal bupivacaine (LB) can be used for postsurgical analgesia after breast reconstruction. We examined real-world clinical and economic benefits of LB versus bupivacaine after deep inferior epigastric perforator (DIEP) flap breast reconstruction.

Methods

This retrospective cohort study used the IQVIA claims databases to identify patients undergoing primary DIEP flap breast reconstruction in 2016-2019. Patients receiving LB and those receiving bupivacaine were compared to assess opioid utilization in morphine milligram equivalents (MMEs) and healthcare resource utilization during perioperative (2 weeks before surgery to 2 weeks after discharge) and 6-month postdischarge periods. A generalized linear mixed-effects model and inverse probability of treatment weighting method were performed.

Results

Weighted baseline characteristics were similar between cohorts (LB, n = 669; bupivacaine, n = 348). The LB cohort received significantly fewer mean MMEs versus the bupivacaine cohort during the perioperative (395 versus 512 MMEs; rate ratio [RR], 0.771 [95% confidence interval (CI), 0.677-0.879]; P = 0.0001), 72 hours after surgery (63 versus 140 MMEs; RR, 0.449 [95% CI, 0.347-0.581]; P < 0.0001), and inpatient (154 versus 303 MMEs; RR, 0.508 [95% CI, 0.411-0.629]; P < 0.0001) periods; postdischarge filled opioid prescriptions were comparable. The LB cohort was less likely to have all-cause inpatient readmission (odds ratio, 0.670 [95% CI, 0.452-0.993]; P = 0.046) and outpatient clinic/office visits (odds ratio, 0.885 [95% CI, 0.785-0.999]; P = 0.048) 3 months after discharge than the bupivacaine cohort; other all-cause healthcare resource utilization outcomes were not different.

Conclusions

LB was associated with fewer perioperative MMEs and all-cause 3-month inpatient readmissions and outpatient clinic/office visits than bupivacaine in patients undergoing DIEP flap breast reconstruction.

Acceptance of outpatient enhanced recovery after surgery (ERAS©) protocols for implant-based breast reconstruction nudged on by the COVID-19 pandemic

We retrospectively identified 295 women undergoing outpatient implant breast reconstruction (IBR) who received standardized ERAS care pre-pandemic (PP; April 2018-March 2020) and during the pandemic (DP; April 2020-March 2022). The majority of IBR was completed as outpatient surgeries DP versus PP (73% versus 38%, p < 0.001). Immediate IBR increased DP versus PP (p < 0.001). Preoperative ERAS© order sets were used 54% of the time. Lack of ERAS© order set use was associated with unplanned admissions (55.3% versus 44.7%, p = 0.02). COVID-19 changed health care and nudged IBR to outpatient procedures. With ERAS© recommendations, IBR can be safely and effectively transitioned to outpatient settings.

Enhanced Recovery After Surgery in Immediate DIEP Flap Breast Reconstruction: Reducing Length of Stay and Opioid Use

Background: To improve patient outcomes amid reduced healthcare resources during the COVID-19 pandemic, a single Canadian cancer center implemented an Enhanced Recovery After Surgery (ERAS) protocol for autologous DIEP flap breast reconstruction. Methods: This retrospective cohort study included 100 consecutive patients undergoing microsurgical breast reconstruction with DIEP flaps using the ERAS protocol and 100 patients using a standard protocol. Primary outcomes were the hospital length of stay and opioid use. Secondary outcomes included postoperative complications, laxative and antiemetic consumption. Results: In this study, 80% of the patients had immediate reconstruction, while the remaining patients received either delayed immediate or delayed reconstruction. Patients in the ERAS group had shorter hospital stays (2.8 vs 4.5 days; P < 0.001) and lower total opioid use (50.2 vs 136.3 mg; P < 0.001). This reduction was also observed when breaking down opiates per day of hospitalization (30.2 vs 18.2 mg; P < 0.001), and in the first 24 postoperatively hours (35.7 vs 67.6 mg; P < 0.001). The control group had a higher incidence of postoperative complications, including seroma, partial and total flap necrosis, compared to the ERAS group. However, readmission rates were similar between the two groups. Conclusion: Implementing the ERAS protocol for DIEP flap breast reconstruction can significantly reduce hospital length of stay and postoperative opioid requirements without increasing the risk of adverse events. This pattern holds true for immediate reconstructions with DIEP flaps.

Efficacy of the enhanced recovery after surgery protocol on reducing surgical disparities related to overweight/obesity in deep inferior epigastric perforator flap breast reconstruction

BACKGROUND

When choosing a method of deep inferior epigastric perforator (DIEP) flap for breast reconstruction, concerns regarding the potentially detrimental effects of obesity on postoperative recovery remain. Enhanced recovery after surgery (ERAS) is known to facilitate rapid postoperative recovery. This study aimed to examine the effect of the ERAS protocol on the disparity between normal/underweight and overweight/obese patients after DIEP flap breast reconstruction.

METHODS

A retrospective review of consecutive patients who underwent DIEP flap breast reconstruction between January 2015 and November 2022 was conducted. The patients were categorized into two groups: pre-ERAS and post-ERAS. In each group, associations between overweight/obese patients (BMI ≥25 kg/m2 ) and postoperative course were evaluated.

RESULTS

In total, 217 patients in the pre-ERAS group (including 71 overweight/obese) and 165 in the post-ERAS group (including 58 overweight/obese) were analyzed. The post-ERAS group had shorter length of stay (LOS) (8.0 versus 7.0 days, p-value <.001) and lower postoperative pain scores (5.0 versus 3.0 at postoperative day (POD) 1, p-value <.001) than the pre-ERAS group. The complication profiles did not differ according to ERAS adoption. In the pre-ERAS group, overweight/obese patients showed a significantly longer LOS (8.0 versus 9.0 days, p-value = .017) and a higher postoperative pain score (3.0 versus 4.0 at POD 2, p-value = .018) than normal/underweight patients; however, these differences disappeared in the post-ERAS group, showing similar LOS, pain scores, and analgesic consumption.

CONCLUSIONS

Implementation of the ERAS protocol in DIEP free-flap breast reconstruction may reduce overweight/obesity-related disparities in postoperative recovery.

Safety of Drainless Donor Closure in DIEP Flap-Based Breast Reconstruction: A Prospective Analysis Using Ultrasound

BACKGROUND

 Although drainless donor closure with progressive tension suture (PTS) technique has been attempted to further reduce donor morbidity in deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, its clinical safety has not yet been fully elucidated. This study prospectively investigated donor morbidity after DIEP flap elevation and drain-free donor closure.

METHODS

 A prospective cohort study was performed on 125 patients who underwent DIEP flap-based breast reconstruction and drainless donor closure. Postoperatively, the donor site was evaluated repetitively using ultrasonography. Development of donor complications, including any fluid accumulation and seroma (defined as detection of fluid accumulation after postoperative one month), was prospectively noted, and independent predictors for the adverse events were evaluated.

RESULTS

 On ultrasound examination conducted within postoperative 2 weeks, 48 patients were detected to have fluid accumulation at the donor site, which were more frequently detected in cases of delayed reconstruction and those with lesser number of PTS conducted. The majority of those events (95.8%) were resolved with one- or two-times ultrasound-guided aspirations. Five patients (4.0%) showed persistent fluid accumulation after postoperative 1 month, which were successfully treated with repetitive aspiration without requiring reoperation. No other abdominal complications developed except for three of delayed wound healing. On multivariable analyses, harvesting larger-sized flap and conducting lesser number of PTS were independent predictors for the development of fluid accumulation.

CONCLUSION

 The results of this prospective study suggest that drainless donor closure of the DIEP flap with meticulous placement of PTS followed by postoperative ultrasound surveillance appears to be safe and effective.

Moving the needle: a narrative review of enhanced recovery protocols in breast reconstruction

Background and Objective

After a relatively late introduction to the literature in 2015, enhanced recovery protocols for breast reconstruction have flourished into a wealth of reports. Many have since described unique methodologies making improved offerings with superior outcomes attainable. This is a particularly interesting procedure for the study of enhanced recovery as it encompasses two dissident approaches. Compared to implant-based reconstruction, autologous free-flap reconstruction has demonstrated superiority in a range of long-term metrics at the expense of historically increased peri-operative morbidity. This narrative review collates reports of recovery protocols for both approaches and examines methodologies surrounding the key pieces of a comprehensive pathway.

Methods

All primary clinical reports specifically describing enhanced recovery protocols for implant-based and autologous breast reconstruction through 2022 were identified by systematic review of PubMed and Embase libraries. Twenty-five reports meeting criteria were identified, with ten additional reports included for narrative purpose. Included studies were examined for facets of innovation from the pre-hospital setting through outpatient follow-up. Notable findings were described in the context of a comprehensive framework with attention paid to clinical and basic scientific background. Considerations for implementation were additionally discussed.

Key Content and Findings

Of 35 included studies, 29 regarded autologous reconstruction with majority focus on reduction of peri-operative opioid requirements and length of stay. Six regarded implant-based reconstruction with most discussing pathways towards ambulatory procedures. Eighty percent of included studies were published after the 2017 consensus guidelines with many described innovations to this baseline. Pathways included considerations for pre-hospital, pre-operative, intra-operative, inpatient, and outpatient settings. Implant-based studies demonstrated that safe ambulatory care is accessible. Autologous studies demonstrated a trend towards discharge before post-operative day three and peri-operative opioid requirements equivalent to those of implant-based reconstructions.

Conclusions

Study of enhanced recovery after breast reconstruction has inspired paradigm shift and pushed limits previously not thought to be attainable. These protocols should encompass a longitudinal care pathway with optimization through patient-centered approaches and multidisciplinary collaboration. This framework should represent standard of care and will serve to expand availability of all methods of breast reconstruction.

Enhanced recovery after surgery pathways for deep inferior epigastric perforator flap breast reconstruction: A systematic review and meta-analysis

BACKGROUND

Deep inferior epigastric perforator (DIEP) surgery is one of the most difficult breast reconstruction techniques available, both in terms of operating complexity and patient recovery. Enhanced recovery after surgery (ERAS) pathways were recently introduced in numerous subspecialties to reduce recovery time, patient pain, and cost by providing multimodal perioperative care. Plastic surgery has yet to widely integrate ERAS with DIEP reconstruction, mostly due to insufficient data on patient outcomes with this combined approach.

METHODS

Five major medical databases were queried using predetermined search criteria according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Statistical analysis was performed using Cochrane's RevMan (v5.4).

RESULTS

A total of 466 articles were identified. A total of 14 studies were included in the review with a combined sample of 2102 patients. Eight studies were included in the meta-analysis with a combined sample of 1679 patients. On average, the included studies utilized 11.69 of 18 suggested protocols for ERAS with breast reconstruction. Our primary outcome, length of stay, was reduced by a mean of 1.12 (95% confidence interval [CI] [-1.30, -0.94], n = 1627, p < 0.001) days in the ERAS group. Postoperative oral morphine equivalents (OME) were also reduced in the ERAS group by 104.02 (95% CI [-181.43, -26.61], n = 545, p = 0.008) OME. The ERAS group saw a significant 3.54 (95% CI [-4.43, -2.65], n = 527, p < 0.001) standardized mean difference cost reduction relative to the control groups. The surgery time was reduced by 60.46 (95% CI [-125, 4.29], n = 624, p < 0.07) min, although this was not statistically significant.

CONCLUSIONS

The ERAS pathway in DIEP breast reconstruction is consistently associated with reduced hospital stay, opioid use, and patient cost. Moreover, there appears to be no evidence of serious adverse outcomes associated with the application of the ERAS protocol.

Faster Return to Daily Activities and Better Pain Control: A Prospective Study of Enhanced Recovery After Surgery Protocol in Breast Augmentation

BACKGROUND

Enhanced recovery after surgery (ERAS) has been proven to decrease the amount of opioid use and reduce postoperative pain for a variety of surgeries, including breast reconstruction. However, data on ERAS in breast augmentation is lacking.

OBJECTIVES

This study aims to investigate the effectiveness and safety of ERAS for breast augmentation.

METHODS

A standardized ERAS protocol was established with full consideration of all aspects of perioperative care. Patients undergoing implant-based breast augmentation were prospectively recruited between December 2020 and January 2023, and assigned to either the ERAS or non-ERAS group randomly. The primary outcome was the activity of daily living after surgery. The secondary was postoperative pain and other outcomes included time to freely elevation, vomiting frequency, the use of analgesics, and complications.

RESULTS

A total of 122 patients were included, with 70 in the ERAS group and 52 in the non-ERAS group. Compared to non-ERAS patients, ERAS patients had a shorter time to freely elevation of upper limbs (2.3 d vs. 5.5 d, P < 0.001). For ERAS patients, the pain scores were significantly lower on postoperative days 1 to 3, the activity of daily living index was significantly higher on postoperative days 1 to 3 and the opioids consumption was decreased (7.1 mg vs. 46.2 mg, P = 0.018). No difference was observed in complication and hospital costs between the two groups.

CONCLUSION

The ERAS protocol significantly reduced postoperative pain and the use of opioids and promoted a return to daily activities without increasing complications in breast augmentation.

Survey of Surgeon-reported Postoperative Protocols for Deep Inferior Epigastric Perforator Flap in Breast Reconstruction

Background

The use of deep inferior epigastric perforator (DIEP) flaps is a well-established breast reconstruction technique.

Methods

A 29-question survey was e-mailed to 3186 active American Society of Plastic Surgeons members, aiming to describe postoperative monitoring practice patterns among surgeons performing DIEP flaps.

Results

From 255 responses (8%), 79% performing DIEP surgery were analyzed. Among them, 34.8% practiced for more than 20 years, 34.3% for 10-20 years, and 30.9% for less than 10 years. Initial 24-hour post-DIEP monitoring: intensive care unit (39%) and floor (36%). Flap monitoring: external Doppler (71%), tissue oximetry (41%), and implantable Doppler (32%). Postoperative analgesia: acetaminophen (74%), non-steroidal anti-inflammatory drugs (69%), neuromodulators (52%), and opioids (4.4%) were administered on a scheduled basis. On postoperative day 1, 61% halt intravenous fluids, 67% allow ambulation, 70% remove Foley catheter, and 71% start diet. Most surgeons discharged patients from the hospital on postoperative day 3+. Regardless of experience, patients were commonly discharged on day 3. Half of the surgeons are in academic/nonacademic settings and discharge on/after day 3.

Conclusions

This study reveals significant heterogeneity among the practice patterns of DIEP surgeons. In light of these findings, it is recommended that a task force be convened to establish standardized monitoring protocols for DIEP flaps. Such protocols have the potential to reduce both the length of hospital stays and overall care costs all while ensuring optimal pain management and vigilant flap monitoring.

Postoperative Day 1 Discharge in Deep Inferior Epigastric Artery Perforator Flap Breast Reconstruction

With high success rates of autologous breast reconstruction, the focus has shifted from flap survival to improved patient outcomes. Historically, a criticism of autologous breast reconstruction has been the length of hospital stay. Our institution has progressively shortened the length of stay after deep inferior epigastric artery perforator (DIEP) flap reconstruction and began discharging select patients on postoperative day 1 (POD1). The purpose of this study was to document our experience with POD1 discharges and to identify preoperative and intraoperative factors that may identify patients as candidates for earlier discharge.

Methods

An institutional review board-approved, retrospective chart review of patients undergoing DIEP flap breast reconstruction from January 2019 to March 2022 at Atrium Health was completed, consisting of 510 patients and 846 DIEP flaps. Patient demographics, medical history, operative course, and postoperative complications were collected.

Results

Twenty-three patients totaling 33 DIEP flaps were discharged on POD1. The POD1 group and the group of all other patients (POD2+) had no difference in age, ASA score, or comorbidities. BMI was significantly lower in the POD1 group (P = 0.039). Overall operative time was significantly lower in the POD1 group, and this remained true when differentiating into unilateral operations (P = 0.023) and bilateral operations (P = 0.01). No major complications occurred in those discharged on POD1.

Conclusions

POD1 discharge after DIEP flap breast reconstruction is safe for select patients. Lower BMI and shorter operative times may be predictive in identifying patients as candidates for earlier discharge.

Rise of Acellular Dermal Matrix: Cost Consciousness, Industry Payment, and Publication Productivity

BACKGROUND

Despite high cost and lack of FDA approval for breast surgery, acellular dermal matrix (ADM) has become commonplace in reconstructive surgery and has been the focus of more than 500 plastic surgery publications since its wide adoption. We hypothesized that ADM-related academic output would correlate with public interest and industry funding.

STUDY DESIGN

All PubMed-indexed studies focusing on ADM in 11 plastic surgery journals were included (n = 535). Data on industry funding to the 17 most productive authors were extracted from the Open Payments Database. Google Trends in "breast surgery cost" and related terms were queried. Relationships among publication quantity, author industry funding, and public interest were analyzed by Pearson's correlation and linear regression.

RESULTS

The most published authors produced 8 qualifying publications on average (range 5 to 17), with 80% focused on breast surgery. These individuals grossed a total of $19 million industry dollars overall with $17 million (89%) in nonconsulting compensation from ADM-producing companies (NC-ADM). Individual total compensation and NC-ADM compensation, by quartile, were $194,000/$320,000/$1.25 million and $17,000/$210,000/$1.1 million, respectively. These variables showed strong correlation with individual publication rate with a linear regression coefficient of $110K in NC-ADM per publication (p < 0.01). Authors disclosed funding in a mean ± SD of 65 ± 26% of their work with strong correlation between disclosure and NC-ADM (p < 0.01). Google "breast surgery cost" search volume has grown rapidly in significant correlation with ADM publications (p = 0.02).

CONCLUSIONS

This study demonstrates significant correlation between ADM-related publication, industry funding, funding disclosure, and public interest. Education in the potential for such relationships and the importance of objectivity in plastic surgery warrants discussion.

"Spin" in Observational Studies in Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Systematic Review

The deep inferior epigastric artery perforator (DIEP) flap is widely used in autologous breast reconstruction. However, the technique relies heavily on nonrandomized observational research, which has been found to have high risk of bias. "Spin" can be used to inappropriately present study findings to exaggerate benefits or minimize harms. The primary objective was to assess the prevalence of spin in nonrandomized observational studies on DIEP reconstruction. The secondary objectives were to determine the prevalence of each spin category and strategy.

Methods

MEDLINE and Embase databases were searched from January 1, 2015, to November 15, 2022. Spin was assessed in abstracts and full-texts of included studies according to criteria proposed by Lazarus et al.

Results

There were 77 studies included for review. The overall prevalence of spin was 87.0%. Studies used a median of two spin strategies (interquartile range: 1-3). The most common strategies identified were causal language or claims (n = 41/77, 53.2%), inadequate extrapolation to larger population, intervention, or outcome (n = 27/77, 35.1%), inadequate implication for clinical practice (n = 25/77, 32.5%), use of linguistic spin (n = 22/77, 28.6%), and no consideration of the limitations (n = 21/77, 27.3%). There were no significant associations between selected study characteristics and the presence of spin.

Conclusions

The prevalence of spin is high in nonrandomized observational studies on DIEP reconstruction. Causal language or claims are the most common strategy. Investigators, reviewers, and readers should familiarize themselves with spin strategies to avoid misinterpretation of research in DIEP reconstruction.

A Single-center Comparison of Unipedicled and Bipedicled Diep Flap Early Outcomes in 98 Patients

The deep inferior epigastric perforator (DIEP) flap is the gold standard for autologous breast reconstruction. One or two pedicles may be used. Our study is the first to compare unipedicled and bipedicled DIEP flaps on donor and recipient site outcomes in the same patient cohort.

Methods

This is a retrospective cohort study comparing DIEP flap outcomes between 2019 and 2022.

Results

There were 98 patients, categorized differently for recipient or donor site. The recipient groups were unilateral unipedicled (N = 52), bilateral unipedicled (N = 15), and unilateral bipedicled (N = 31), and donor site groups were unipedicled (N = 52) and bipedicled (N = 46, including bilateral unipedicled and unilateral bipedicled). Bipedicled DIEP flaps had 1.15 times greater odds of donor site complication (95% CI, 0.52-2.55). Adjusting for operative time that was longer in bipedicled DIEP flaps (P < 0.001), odds ratio decreased, and there was a lower probability of donor site complication for bipedicled flaps (OR, 0.84; 95% CI, 0.31-2.29). Odds of recipient area complication was not significantly different between groups. Unilateral unipedicled DIEP flaps had significantly higher rates of revisional elective surgery than unilateral bipedicled DIEP flaps (40.4% versus 12.9%; P = 0.029).

Conclusions

We demonstrate no significant difference in donor site morbidity between unipedicled and bipedicled DIEP flaps. Bipedicled DIEP flaps do have slightly higher rates of donor site morbidity, which can be partly explained by longer operative times. There is no significant difference in recipient site complications, and bipedicled DIEP flaps can reduce rates of further elective surgery.

Pushing the DIEP Envelope with ERAS: 24 Hour Discharge is Safe in Appropriately Selected Patients

Enhanced recovery after surgery protocols have become increasingly adopted for autologous breast reconstruction, demonstrating improved quality of care and reduced hospital stays. Despite this, average length of stay remains over 3 days. We have found, in appropriately selected patients, hospital length of stay can be safely reduced to less than 48 hours.

Methods

Retrospective review was performed of patients who underwent microsurgical breast reconstruction by the senior author (M.H.) from April 2019 to December 2021. Demographics, operative details, length of stay, and postoperative complications are reported to assess for safety of discharge within 48 hours, with the primary outcome measure being flap loss.

Results

In total, 188 flaps were performed on 107 patients. Average age was 51.4 years (SD 10.1 years) with average BMI 26.6 kg/m² (SD 4.8 kg/m²). Average length of stay was 1.97 days (SD 0.61 days), and 96 patients (89.7%) were discharged within 48 hours. Six flaps (3.2%) required operative takebacks. Five of the six (83.3%) takebacks occurred on postoperative days zero or one, and all five of these flaps were salvaged. There were four breast hematomas (2.1%), four breast seromas (2.1%), eight breast infections (4.3%), 13 breasts (6.9%) with wound dehiscence, four flaps (2.1%) with partial flap loss, and 24 breasts (12.8%) with mastectomy flap necrosis. One hundred fifty flaps (79.8%) had no complications. Overall success rate of flap reconstruction was 99.5%.

Conclusion

Hospital discharge in 24-48 hours is safe in appropriately selected patients undergoing autologous tissue breast reconstruction.

Assessing the quality of reporting on quality improvement initiatives in plastic surgery: A systematic review

BACKGROUND

There has been a recent increase in the number and complexity of quality improvement studies in plastic surgery. To assist with the development of thorough quality improvement reporting practices, with the goal of improving the transferability of these initiatives, we conducted a systematic review of studies describing the implementation of quality improvement initiatives in plastic surgery. We used the SQUIRE 2.0 (Standards for Quality Improvement Reporting Excellence) guideline to appraise the quality of reporting of these initiatives.

METHODS

English-language articles published in Embase, MEDLINE, CINAHL, and the Cochrane databases were searched. Quantitative studies evaluating the implementation of quality improvement initiatives in plastic surgery were included. The primary endpoint of interest in this review was the distribution of studies per SQUIRE 2.0 criteria scores in proportions. Abstract screening, full-text screening, and data extraction were completed independently and in duplicate by the review team.

RESULTS

We screened 7046 studies, of which 103 full texts were assessed, and 50 met inclusion criteria. In our assessment, only 7 studies (14%) met all 18 SQUIRE 2.0 criteria. SQUIRE 2.0 criteria that were met most frequently were abstract, problem description, rationale, and specific aims. The lowest SQUIRE 2.0 scores appeared in funding, conclusion, and interpretation criteria.

CONCLUSIONS

Improvements in QI reporting in plastic surgery, especially in the realm of funding, costs, strategic trade-offs, project sustainability, and potential for spread to other contexts, will further advance the transferability of QI initiatives, which could lead to significant strides in improving patient care.

EFFECTS OF DIEP FLAP-BASED BREAST RECONSTRUCTION ON RESPIRATORY FUNCTION

BACKGROUND

Breast reconstruction (BR) is an essential part of breast cancer treatment, and the DIEP flap is considered the gold standard reconstruction technique, which uses a free abdominal flap. Concerns have been raised regarding the effects of abdominoplasty on respiratory functions. This topic has not been addressed regarding donor-site closure of DIEP flaps. Our aim is to prospectively compare preoperative and postoperative spirometry in patients undergoing DIEP flap-based BR, investigating its impact on respiratory function.

MATERIALS AND METHODS

We enrolled 21 patients who received BR with DIEP flap in our institution, who underwent pulmonary function assessment by spirometry 1 month preoperatively and 1 year postoperatively. We assessed Forced Expiratory Volume in the first second (FEV1), Forced Vital Capacity (FVC), FEV1/FVC ratio, and Peak Expiratory Flow (PEF). Statistical analysis was performed using the paired samples test.

RESULTS

An improvement in the mean values of all 4 variables was found at 1 year from surgery. Namely, FEV1 improved by 0.1 L with a standard deviation (SD) of 0.39 L, FVC by 0.04 L with SD of 0.627, FEV1/FVC by 2.11 L with SD of 7.85 L, and PEF by 1.2 L with SD of 1.45 L. Only PEF was statistically significant [P = 0.001].

CONCLUSION

Our results suggest that DIEP flap BR does not negatively impact respiratory function. Although further knowledge is required, we confirm the possibility of considering the indication for abdominoplasty and DIEP flap reconstruction in patients with altered and reduced pulmonary function.

Enhanced Recovery after Surgery (ERAS) in DIEP-Flap Breast Reconstructions-A Comparison of Two Reconstructive Centers with and without ERAS-Protocol

Enhanced recovery after surgery (ERAS) is established for autologous breast reconstruction. ERAS leads to a shortened hospital stay and improved outcome after elective surgery. In this retrospective, two-center case−control study, we compared two different treatment regimens for patients undergoing a DIEP-flap breast reconstruction from two centers, one with an established ERAS protocol and one without. All patients with DIEP breast reconstructions over the period of 12 months were included. The primary outcome measure was the length of hospital stay (LOS) in days. A total of 79 patients with 95 DIEP-flaps were analyzed. In group A (ERAS) 42 patients were operated with DIEP flaps, in group B (non-ERAS) 37 patients. LOS was significantly reduced in the ERAS group (4.51 days) compared to the non-ERAS group (6.32; p < 0.001). Multivariate analysis showed that, in group A, LOS is significantly affected by surgery duration. BMI in the ERAS group had no effect on LOS. In group B a higher BMI resulted in a significantly higher LOS. In multivariate analysis, neither age nor type for surgery (primary/secondary/after neoadjuvant therapy, etc.) affected LOS. In both groups, no systemic or flap-related complications were observed. Comparing two reconstructive centers with and without implemented ERAS, ERAS led to a significantly decreased LOS for all patients. ERAS implementation does not result in an increased complication rate or flap loss. Postoperative pain can be well managed with basic analgesia using NSAID when intraoperative blocks are applied. The reduced use of opioids was well tolerated. With implementation of ERAS the recovery experience can be enhanced making autologous breast reconstructions more available and attractive for various patients.
