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.

The largest perforator of DIEP flap has a higher rate of continuity with the superficial inferior epigastric artery.

BACKGROUND: In deep inferior epigastric artery (DIEA) perforator (DIEP) flap breast reconstruction, the network with the superficial inferior epigastric artery (SIEA) is key to achieving stable subcutaneous blood flow to the flap. This study investigated how the diameter and location of the DIEA perforator affect continuity with the SIEA. METHODS: A retrospective analysis of 94 specimens from 47 patients who underwent DIEA perforator flap breast reconstruction was performed. Relationships between the diameter and location of the DIEA perforator and its continuity with the SIEA were examined on preoperative multi-slice computed tomography. RESULTS: The largest DIEA perforator on each specimen showed continuity with the SIEA in 94 %, significantly more than the second (80 %; p = 0.027) or third largest perforator (76 %; p = 0.005). Medial perforators from 3 cm above to 3 cm below the umbilicus showed more continuity with the SIEA than lateral perforators (p = 0.008). CONCLUSIONS: Selection of the largest perforator of DIEP flap is advantageous in terms of continuity with the SIEA. Also, near the umbilicus, medial perforators communicate with the SIEA more than lateral perforators.

The Role of Deep Inferior Epigastric Perforator and Thoracodorsal Artery Perforator Flaps in Head and Neck Reconstruction.

Head and neck reconstruction has evolved to a more accurate replacement of the missing tissues for aesthetic and functional benefits, besides a concern with the morbidity caused in the donor site. This has led us to the use of perforator flaps. Deep inferior epigastric perforator flap allows the harvest of a large well-vascularized skin paddle with adequate bulk for large and voluminous defects reconstruction. Its main uses described in the literature are: tongue reconstruction, orbitomaxillary reconstruction, and scalp reconstruction. Thoracodorsal artery perforator flap is derived from the subscapular system and allows the harvest of a large array of chimeric flaps.

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.

Outcomes of Deep Inferior Epigastric Artery Perforator (DIEP) Flap in Indian Population-A Prospective Single-Institute Study.

Introduction Breast reconstruction has become integral part of breast cancer treatment. Deep inferior epigastric perforator (DIEP)-based flap is considered the gold standard in autologous breast reconstruction. Aims and Objectives The aim of this study was to evaluate the patient satisfaction and the incidence of complications in DIEP flaps in an Indian setup for breast reconstruction. Materials and Methods This is a prospective, nonrandomized study at a single institute-Manipal Hospitals, Old Airport Road, Bangalore. Eligible patients were women aged between 28 and 60 years with primary breast cancer requiring mastectomy and radiotherapy, who consented for DIEP flap reconstruction. Results The study includes subjects who had autologous breast reconstruction after mastectomy with DIEP flap between January 2019 and August 2021 that included 31 patients with a minimum follow-up of 2 years. Four flaps were turbocharged and 17 flaps were superdrained primarily. The average operative time for the whole procedure by adopting a two-team approach is 353.8 ± 43.793 minutes. About 94.1% patients had excellent aesthetic score results. Six patients developed mastectomy flap necrosis, one had fat necrosis that was managed conservatively, whereas one patient had donor site re-exploration for hematoma. We had no DIEP flap necrosis, seroma, flap site hematoma, or flap failure. Physical well-being module of Breast-Q indicated an average of 83 points, psychosocial well-being module indicated 80 points, whereas sexual scores reverted an average of 77 points. Among satisfaction module, aesthetic outcomes for breast showed an average of 94 points, whereas the donor site had 96 points. Satisfaction with information, surgeon, medical staff each gained more than 87 points. Conclusion Breast reconstruction with DIEP flap yields good aesthetic outcomes and quality of life in Indian population. The incidence of fat necrosis, flap and donor site complications is less over time and will enhance the patient satisfaction score further.

Abdominal donor-site complications following autologous breast reconstruction: A multi-institutional multisurgeon study.

BACKGROUND: The deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood. METHODS: We examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics. RESULTS: A total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04-1.18, p = 0.001), seroma (OR 1.07, CI 1.01-1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06-1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05-1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108-0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population. CONCLUSIONS: Higher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

Microsurgical training curriculum in a gynecological breast cancer center: a benefit for patients and surgeons?

PURPOSE: Autologous breast reconstruction improves patient satisfaction and quality of life after mastectomy. In Germany, free flap surgery and implant-based reconstruction is usually separate between reconstructive surgery and gynecology. Cooperation between the specialist disciplines and implementation of microsurgery into breast surgeon training could enhance surgical treatment for breast cancer patients. This evaluation is intended to demonstrate the learning progress within a microsurgical training program and the complication rate in relation to microsurgical experience. METHODS: At the breast cancer center at Klinikum rechts der Isar, TU Munich, a three-stage training program for autologous breast reconstruction and microsurgery for gynecological breast surgeons was developed. Between 2019 and 2022, 74 women received autologous free flap breast reconstruction by a consistent team consisting of a gynecological surgeon in training and an expert microsurgeon. Peri- and postoperative data were collected to analyze the feasibility and safety of a microsurgical training in gynecology. RESULTS: Within the training, operative steps of free autologous breast reconstruction were increasingly taken over by the gynecological surgeon in training. The analysis showed a decrease in operating times with consistently low complication rates during the training. CONCLUSION: This study demonstrated that a training in free autologous breast reconstruction for gynecological surgeons is safely feasible through close cooperation between gynecological and reconstructive surgery.

Surgical Considerations of One-Stage Reconstruction of Large Extremity Defects Using a Thin Deep Inferior Epigastric Perforator Flap.

Background One-stage reconstruction with "thin perforator flaps" has been attempted to salvage limbs and restore function. The deep inferior epigastric perforator (DIEP) flap is a commonly utilized flap in breast reconstruction (BR). The purpose of this study is to present the versatility of DIEP flaps for the reconstruction of large defects of the extremities. Methods Patients with large tissue defects on extremities who were treated with thin DIEP flaps from January 2016 to January 2018 were included. They were minimally followed up for 36 months. We analyzed the etiology and location of the soft tissue defect, flap design, anastomosis type, outcome, and complications. We also considered the technical differences in the DIEP flap between breast and extremity reconstruction. Results Overall, six free DIEP flaps were included in the study. The flap size ranged from 15 × 12 to 30 × 16 cm 2 . All flaps were transversely designed similar to a traditional BR design. Three flaps were elevated with two perforators. Primary closure of the donor site was possible in all cases. Five flaps survived with no complications. However, partial necrosis occurred in one flap. Conclusion A DIEP flap is not the first choice for soft tissue defects, but it should be considered for one-stage reconstruction of large defects when the circulation zone of the DIEP flap is considered. In addition, this flap has many advantages over other flaps such as provision of the largest skin paddle, low donor site morbidity with a concealed scar, versatile supercharging technique, and a long pedicle.

Building Complex Autologous Breast Reconstruction Program: A Preliminary Experience.

Autologous breast reconstruction is an increasingly popular method of reconstruction for breast cancer survivors. While deep inferior epigastric perforator (DIEP) flaps are the gold standard, not all patients are ideal candidates for DIEP flaps due to low BMI, body habitus, or previous abdominal surgery. In these patients, complex autologous breast reconstruction can be performed, but there is a limited number of programs around the world due to high technical demand. Given the increased demand and need for complex autologous flaps, it is critical to build programs to increase patient access and teach future microsurgeons. In this paper, we discuss the steps, pearls, and preliminary experience of building a complex autologous breast reconstruction program in a tertiary academic center. We performed a retrospective chart review of patients who underwent starting the year prior to the creation of our program. Since the start of our program, a total of 74 breast mounds have been reconstructed in 46 patients using 87 flaps. Over 23 months, there was a decrease in median surgical time for bilateral reconstruction by 124 min (p = 0.03), an increase in the number of co-surgeon cases by 66% (p < 0.01), and an increase in the number of complex autologous breast reconstruction by 42% (p < 0.01). Our study shows that a complex autologous breast reconstruction program can be successfully established using a multi-phase approach, including the development of a robust co-surgeon model. In addition, we found that a dedicated program leads to increased patient access, decreased operative time, and enhancement of trainee education.

Efficacy of superficial inferior epigastric vein superdrainage in free TRAM and DIEP flap: An indocyanine green angiography study of 68 cases.

BACKGROUND: This study aimed to evaluate the clinical efficacy of venous augmentation using superficial inferior epigastric vein (SIEV) in free transverse rectus abdominis musculocutaneous (TRAM) and deep inferior epigastric artery perforator (DIEP) flap and investigate the factors that hinder the venous superdrainage. METHODS: A retrospective review of 62 free muscle-sparing (MS)-TRAM and 6 DIEP unilateral breast reconstructions from September 2017 to July 2022. Intraoperative indocyanine green angiography was performed on the harvested flap, with the SIEV contralateral to the pedicle side clamped and unclamped for 20 min. The relative ratio of hypoperfused area to the total flap area was calculated and compared quantitatively. The preoperative computed tomography (CT) angiography was reviewed to obtain information on the SIEV diameter and number of midline-crossing medial branches. RESULTS: The participants were categorized into three groups: 42 patients in Group 1 (>3% decrease in hypoperfused area), 20 patients in Group 2 (change in hypoperfused area ranging from -3% to 3%), and six patients in Group 3 (>3% increase in hypoperfused area). The mean number of midline-crossing branches (p = 0.002) and mean difference in the diameter of bilateral SIEVs (p = 0.039) were significantly greater in Group 1 than in the other groups. CONCLUSIONS: Thirty-eight percent (26/68 cases) resulted in sustained or aggravated perfusion after SIEV superdrainage. Superdrainage using the contralateral SIEV in free MS-TRAM/DIEP flap is recommended when there are more than two midline-crossing medial branches of SIEV and when the caliber of SIEV is relatively greater compared with the pedicle side.

A Case of Breast Cancer With Ulceration of a Reconstructed Nipple Due to Local Recurrence.

Ulceration of a reconstructed nipple occurred in a woman in her 50s who had undergone mastectomy, axillary lymph node dissection, and deep inferior epigastric artery perforator flap reconstruction for right breast cancer. The implanted cartilage was removed on suspicion of infection and the ulcer was biopsied. Local recurrence was identified on histopathological examination. Local recurrence near a reconstructed nipple can cause ulceration because of the fragility of the reconstructed nipple tissue. If erosion or ulceration develops in the reconstructed nipple relatively long after surgery, pathological examination is warranted.

Consecutive bilateral breast reconstruction using different autologous flaps: can symmetrical results still be achieved? A case report.

We report a 60-year-old patient who underwent bilateral mastectomy at different times, followed by immediate autologous reconstruction with different flaps: deep-inferior epigastric-perforator flap on one breast, and fat-augmented latissimus dorsi on the contralateral side. At 20-month follow-up, good symmetry was recorded; patient-reported outcome measurements revealed high satisfaction scores.

Digital reconstruction technology in assisted design of lobulated deep inferior epigastric perforator flap for reconstruction of large defect in lower extremity / 中华显微外科杂志

Objective:To investigate the efficacy of digital reconstruction technology in assisted design of lobulated deep inferior epigastric perforator flap (DIEPF) for surgical reconstruction of large defect in lower extremity.Methods:From January 2017 to January 2022, a study was carried out to retrospectively analyse 8 patients who had massive soft tissue defects in lower extremities were admitted in the Department of Orthopaedic Surgery of the 920 Hospital of Joint Logistic Support Force of Chinese PLA. The size of defects varied from 16.0 cm×12.0 cm-28.0 cm×22.0 cm. CTA scans were performed over abdominal aorta and the arteries of lower extremities. Three-dimensional model of DIEPF and vascular pedicles were reconstructed by Mimics software. According to the shape and size of the wound, targeted perforators were determined on the 3D images, and precisely mapped in a digitised rectangular coordinate system. The lobulated flap was then digitally designed in the 3D coordinate system. Flaps were harvested according to preoperative digital designs for the reconstruction of large defects in the lower extremities. The donor site was sutured directly. The flaps and recovery of lower extremities were observed though postoperative follow-ups and were conducted through visits of outpatient clinics and distance interviews via telephone and WeChat. Recoveries of lower extremities were evaluated using Maryland ankle-foot function scoring system.Results:The 3D reconstructed models of the vessels in donor sites were successfully completed for all patients. The harvests of lobulated DIEPF were successfully guided by the digital designs. Fifteen lobes of lobulated DIEPF survived successfully in all 8 patients. All donor sites were closed in the stage-I. Necrosis occurred at the distal tip of a lobulated flap due to a local venous occlusion, and healed after debridement and re-suture. Four patients received further flap debulking surgery. Time of postoperative follow-ups had ranged 15-27 months, with an average of 20 months. At the last follow-up, all the flaps had satisfactory appearance with linear scars at the donor sites. All fractures were healed. Five patients achieved Maryland's ankle-foot function score in excellent, 2 in good, and 1 was acceptable.Conclusion:Digital reconstruction technology can accurately map the perforators and reasonably assist the design of lobulated flaps. A lobulated DIEPF offers a wider area for flap excision and allows a primary closure of the donor sites. Combination of the 2 advantages of a lobulated DIEPF can be effectively applied in reconstruction of a large-sized defect in lower extremity.

Current status of autologous breast reconstruction in Europe: how to reduce donor site morbidity.

Autologous reconstruction techniques for breast reconstruction have significantly evolved in the last few decades in Europe. In the search of reducing the donor site morbidity, surgeons explored the possibilities to preserve the rectus muscle and its function, and a transition to deep inferior epigastric perforator (DIEP) flaps was started in the nineties. Throughout the years, and especially in the last decade, we have increasingly implemented aesthetic refinements for donor site handling in DIEP flap breast reconstruction. In our practice, autologous breast reconstruction provides an opportunity to effectively remodel the donor site, minimising functional morbidity, and maximising aesthetic satisfaction. To achieve this, careful patient selection, pre-operative preparation, meticulous intra-operative dissection, and a clear post-operative protocol are essential. The main goal in autologous breast reconstruction, and its biggest advantage, is to offer the patient a natural look and feel of the reconstructed breast. A second goal is to minimize the number of procedures needed to reach the desired breast shape, size, and volume. In most patients, the number of operations ranges between one and three. The third main goal is to minimize the donor site morbidity, both functionally and aesthetically. Functionally, this implies preserving as much of the rectus abdominis muscle as possible, limiting the fascia incision, preserving the motor branches to the muscle, ensuring an adequate fascial closure, and repairing the rectus diastasis is present. Aesthetically, we aim to have a low position of the scar, an aesthetically pleasing location of the umbilicus, and limited or no lateral skin excess or so called "dogears". In this clinical practice review article, we provide an overview of current autologous reconstruction methods, with a focus on minimising donor site morbidity and enhancing the aesthetic result of the donor site. We discuss key concepts in autologous reconstruction and provide surgical pearls for performing the procedure effectively with optimal reconstructive and aesthetic result.

Immediate Deep Inferior Epigastric Perforator Flap Reconstruction of a Giant Phyllodes Tumor.

We present a case of a giant phyllodes tumor (PT) requiring simple mastectomy with en bloc pectoralis major resection and immediate deep inferior epigastric perforator (DIEP) flap reconstruction. This patient presented with a four-year history of an enlarging breast mass with ultrasound-guided biopsy results consistent with atypical fibroepithelial proliferation that was highly concerning for a borderline phyllodes tumor. In this large, rare breast tumor that required en bloc pectoralis major resection, we describe the novel use of an immediate single pedicled DIEP flap for the resulting chest wall defect. The patient's postoperative course was uncomplicated, and she reported satisfactory cosmetic and functional outcomes at her initial postoperative follow-up visits. Our findings support the use of simple mastectomy with en bloc resection and immediate single-pedicled DIEP flap for the definitive treatment of giant phyllodes tumors. Our experience shows this is a safe and effective technique for achieving adequate oncologic resection while maintaining postoperative function and cosmesis, which are essential for patient quality of life.

Clinical outcomes following robotic versus conventional DIEP flap in breast reconstruction: A retrospective matched study.

Background: A robotic deep inferior epigastric perforator (DIEP) flap created through a totally extraperitoneal approach minimizes violation of the donor site, which may lead to postoperative pain reduction and rapid recovery. The authors compared the clinical outcomes of robotic and conventional DIEP flap breast reconstructions. Methods: Data from consecutive patients who underwent mastectomy with DIEP flaps for breast reconstruction between July 2017 and January 2021 were retrospectively reviewed. Patients were divided into robotic and conventional DIEP groups, and the two groups were matched using the inverse probability of treatment weighting method. They were compared based on the reconstruction time, drainage amount, postoperative pain, rescue analgesics, hospital stay, complications, and BREAST-Q scores. Results: After matching, a dataset of 207 patients was formed, including 21 patients in the robotic DIEP group and 186 patients in the conventional DIEP group. The mean reconstruction time was longer in the robotic DIEP group than in the conventional DIEP group (P<0.001). In the robotic group, pain intensity during the postoperative 6-24 hours was significantly reduced (P=0.001) with less use of fentanyl (P=0.003) compared to the conventional DIEP group. The mean length of hospital stay for the robotic DIEP group was shorter than that for conventional DIEP (P=0.002). BREAST-Q scores indicated a higher level of the abdominal physical well-being domain in the robotic group (P=0.020). Complication rates were comparable between the two groups. Conclusions: This study suggests that a robotic DIEP flap offers enhanced postoperative recovery, accompanied by a reduction in postoperative pain and hospital stay.
