Latissimus dorsi muscle free flap revisited: a novel endoscope-assisted approach

Case Report: Vertical muscle-sparing latissimus dorsi flap in the reconstruction of chronic radiation-induced chest wall ulcers after breast cancer surgery: a case series

Introduction

Radiation therapy, a standard postoperative treatment for breast cancer, can lead to chronic ulcers owing to compromised tissue healing. Accordingly, flap surgery using healthy tissues is essential for aesthetic and functional recovery. Although various flap techniques exist, each has its own drawbacks. This study introduces the vertical muscle-sparing latissimus dorsi flap as a superior alternative due to its comparative operative efficiency and tissue preservation.

Case report

Two female patients aged 60 and 59 years with histories of breast cancer in their left breast treated with radiotherapy presented with chronic ulcers. The first patient had a 4 × 5 cm defect infiltrating the pleural space, while the second had a 15 × 9 cm defect after thoracic surgery for a bronchopleural fistula. In both cases, debridement was followed by reconstruction using a vertical muscle-sparing latissimus dorsi flap, thereby avoiding the need to change the patient's position and repeated draping during surgery. Both patients showed good postoperative recovery without significant complications.

Results

The vertical muscle-sparing latissimus dorsi flap resulted in better adhesions and functional outcomes due to shorter surgical duration.

Conclusion

The vertical muscle-sparing latissimus dorsi flap is an effective and efficient method for reconstructing radiation-induced chest wall ulcers in patients with breast cancer. Its application in the presented cases highlights its potential as a preferred option in similar clinical scenarios.

Anterior-First Approach for Latissimus Dorsi Myocutaneous Flap Breast Reconstruction: A Refined Elevation Method with Detailed Video Instructions

Background: The latissimus dorsi myocutaneous (LDMC) flap is a preferred flap in breast reconstruction for its wide surface area and volume. Since the flap is situated in the midback area, a lateral decubitus approach is a conventional method. However, proper visualization and access to the thoracodorsal vascular pedicle or muscle insertion is difficult from the lateral approach, causing inefficiency and surgeon fatigue. We propose the ‘anterior-first’ approach in LDMC flap reconstruction, where the landmark structures are first approached from the supine-anterior position through the mastectomy incision. Methods: From January 2014 to December 2020, 48 patients who received immediate breast reconstruction with LDMC flap were included in the study. Patients received reconstruction with the conventional approach (n = 20), or anterior-first approach (n = 28). Demographic factors and the operative outcomes were retrospectively analyzed and compared between the two groups. Results: Compared to the conventional approach group, the anterior-first approach group showed improved efficiency in the duration of total reconstruction (228 versus 330 min, p < 0.001), and flap elevation (139 versus 200 min, p < 0.001). No difference in complication rate and time to drain removal was observed (p = 0.14 and >0.9, respectively). Conclusion: The anterior-first approach for breast reconstruction with LDMC flap provides surgeons with an enhanced surgical exposure and superior ergonomics, leading to a safer and more efficient flap elevation.

The Usefulness of Endoscopic Harvesting of the Latissimus Dorsi Flap for Breast Reconstruction Using a Single-Port and CO2 Gas Insufflation Technique

BACKGROUND

In the recent trend toward less aggressive approaches to breast reconstruction, minimally invasive harvesting of the latissimus dorsi (LD) flaps has long been a desirable goal. Endoscopically-assisted LD flap harvesting was reported as a method for minimizing scar formation and reducing donor-site morbidity. This study investigates the surgical outcomes of endoscopically-assisted immediate breast reconstruction with LD muscle flaps.

MATERIALS AND METHODS

This prospective study included 21 patients who underwent endoscopically-assisted breast reconstruction with LD muscle flap and 20 patients who underwent breast reconstruction with conventional harvesting LD musculocutaneous flap. In patients with nonexcised skin or possible primary closure, the reconstruction was performed with endoscopically-assisted LD muscle flaps using the single-port and CO₂ gas insufflation technique. The patients were classified into groups according to the location of the defect and mastectomy type. Moreover, patient satisfaction was investigated 6 months after surgery.

RESULTS

In patients who underwent endoscopically-assisted breast reconstruction with LD muscle flaps, the scar of the donor-site was vertical, and the size was 4 cm to be obscured when lowering the arms. In comparison with patients who underwent breast reconstruction with conventional LD flaps, those who underwent endoscopically-assisted breast reconstruction with LD muscle flaps showed shorter hospital stay and no difference in patient satisfaction.

CONCLUSION

Endoscopically-assisted breast reconstruction with LD flaps showed no difference in patient satisfaction with good esthetic results compared with conventional LD flaps. The endoscopic LD muscle flap harvest technique using a single-port and CO2 insufflation technique can be very useful in breast reconstruction that does not require a skin paddle.

Chest Wall Reconstruction in Male Poland Syndrome Patients with Endoscopic-Assisted Latissimus Dorsi Muscle Flap Transfer

BACKGROUND

Pectoralis major absence generates chest wall deformity and always requires surgical intervention. This study aimed to introduce a technique to reconstruct the chest wall for male Poland Syndrome patients with endoscopic latissimus dorsi muscle (ELDM) flap via a single transverse axillary incision and evaluate its safety and effectiveness.

METHODS

A prospective study was designed to recruit male Poland Syndrome candidates for ELDM chest reconstruction. By performing a short and hidden transaxillary incision, we created anterior chest wall pocket and transferred the latissimus dorsi muscle (LDM) flap to recontour the chest wall. Data for patient demographics, LDM flap dimension, operative time, and complications were collected. Upper extremity functional disabilities were evaluated by the disabilities of the arm, shoulder and hand (DASH) outcome questionnaire. Satisfaction with the outcome was measured by satisfaction with outcome subscale of the BREAST-Q questionnaire.

RESULTS

This study recruited 11 eligible patients to receive ELDM chest wall reconstruction. ELDM flap harvesting averagely consumed 79.9 minutes. Without significant complications, all patients recovered uneventfully. Chest wall anomalies of different severity were corrected safely and effectively. The score of DASH was 3.7±3.3 preoperatively and 4.0±3.7 postoperatively with no statistically significant difference. The score of satisfaction with the outcome was 84.8±14.3.

CONCLUSIONS

For chest wall anomalies of different severity in male Poland Syndrome patients, the ELDM technique provides a safe and efficient way to reconstruct the chest wall with a better aesthetic outcome, high satisfaction rate, and satisfactory upper limb function.

Breast Reconstruction in Poland Syndrome Patients with Latissimus Dorsi Myo Flap and Implant: An Efficient Endoscopic Approach Using Single Transverse Axillary Incision

BACKGROUND

Breast hypoplasia or amastia with pectoralis major muscle defect in female Poland syndrome patients always necessitates surgical intervention. This study aims to introduce an efficient endoscopic technique to perform breast reconstruction in Poland syndrome patients with a latissimus dorsi myo flap and an implant using a single transverse axillary incision (ELDM + IMPLANT) and to evaluate its safety and effectiveness.

METHODS

A prospective study was designed to recruit Poland syndrome candidates for ELDM + IMPLANT breast reconstruction. Only one transaxillary incision was made to harvest the LDM flap and create the anterior chest wall pocket. The LDM flap was transposed to the front to reconstruct the breast with a silicone implant. Patient demographics, LDM area, implant size, contralateral symmetry surgery, operative time and post-operative complications were collected. The BREAST-Q reconstruction module was used to evaluate patient quality of life. The disabilities of the arm, shoulder and hand (DASH) outcome questionnaire was used to evaluate patient upper extremity disabilities.

RESULTS

Sixteen eligible patients were recruited and received ELDM + IMPLANT-BR. Mean endoscopic time for LDM flap harvesting was 61.6 min. All of the 16 patients recovered uneventfully without any significant complications. The post-operative scores of satisfaction with breast and psychosocial well-being were significantly higher than the pre-operative ones. The score of DASH was 7.1 pre-operatively and 8.3 post-operatively with no significant difference either. The score of satisfaction with outcome was 80.0.

CONCLUSIONS

Our proposed ELDM + IMPLANT technique provides a safe and efficient way to reconstruct breasts in Poland syndrome patients with a high satisfaction rate, optimized aesthetic outcome and minimized donor site morbidity.

A comparison study between endoscope-assisted and the standard approach in the harvesting of the free rectus femoris muscle flap

BACKGROUND

Endoscopic harvesting of muscle flaps is well described for gracilis, latissimus dorsi, gastrocnemius, and pectoralis major amongst others. So far there has been no description of endoscopic harvesting of the rectus femoris muscle as a free flap. The purpose of this study was to compare the perioperative outcomes of harvesting the free rectus femoris muscle flap endoscopically as compared to the standard approach.

METHODS

Fifty patients with lower limb defects reconstructed with free rectus femoris muscle flap between January 2014 and December 2016 were included in this study. Their ages ranged from 37 years old to 92 years old. The flaps were harvested with both the standard and endoscopical method. Comparative data between the two methods collected included: age, gender, comorbid illnesses, flap size, defect size, reconstruction time, and flap survival rate RESULTS: Twenty patients underwent flap harvesting endoscopically and 30 were harvested with the standard technique. Their mean ages were 67 ± 9.4 and 65 ± 14 years old respectively (P = .47). The defect size was 96 ± 60 cm² versus 81 ± 74 cm² (P = .45). The flap size was 72 ± 34 cm² in the endoscopic group and 60 ± 42 cm² in the standard group (P = .52). The mean total reconstruction time in the endoscopic group was 228 ± 48 minutes and 216 ± 64 minutes in the standard group (P = .50). There was no significant difference between flap survival (P = N/A), complication rates (P = .33), and length of admission (P = .84) in the two groups.

CONCLUSION

Endoscope-assisted harvesting of a free rectus femoris muscle flap is a feasible option and permits a small scar at the donor site.

Scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of a maxillectomy defect: A minimally invasive transaxillary approach

The purpose of this study was to propose a novel, minimally invasive transaxillary approach for harvesting the scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of a maxillectomy defect. A retrospective case series study of 4 patients who underwent reconstruction using a scapular tip composite free flap through the transaxillary approach was conducted. The data (age, sex, pathology, previous treatment and adjuvant treatment) were collected and analysed. Total operation time, number of hospital days and the cosmetic and functional outcome of reconstruction were analysed. Two male and two female patients were enrolled in this study. The patients' ages ranged from 52 to 59 years. All the patients had maxillectomy defects, with at least a classification of Okay type II, which were successfully reconstructed using a scapular tip and latissimus dorsi free flap through a minimally invasive transaxillary approach. The entire operation time for the primary tumour surgery and reconstruction ranged from 6.2 to 12.1 h (mean, 11.1 h). The average length of the hospital stay was 13 days (range, 10-16 days). No major donor site morbidity was observed, and there was no graft failure that required revision or exploration surgery. The minimally invasive transaxillary approach for harvesting the scapular tip and latissimus dorsi osteomyogenous free flap for the reconstruction of maxillectomy defect is a promising approach for more favourable functional and aesthetic outcomes when compared to the use of other bone containing free flaps and the classic approach for harvesting scapular tip and latissimus dorsi free flap.

Immediate partial breast reconstruction with endoscopic latissimus dorsi muscle flap harvest

Background

Currently, breast conservation therapy is commonly performed for the treatment of early breast cancer. Depending on the volume excised, patients may require volume replacement, even in cases of partial mastectomy. The use of the latissimus dorsi muscle is the standard method, but this procedure leaves an unfavorable scar on the donor site. We used an endoscope for latissimus dorsi harvesting to minimize the incision, thus reducing postoperative scars.

Methods

Ten patients who underwent partial mastectomy and immediate partial breast reconstruction with endoscopic latissimus dorsi muscle flap harvest were reviewed retrospectively. The total operation time, hospital stay, and complications were reviewed. Postoperative scarring, overall shape of the reconstructed breast, and donor site deformity were assessed using a 10-point scale.

Results

In the mean follow-up of 11 weeks, no tumor recurrence was reported. The mean operation time was 294.5 (±38.2) minutes. The postoperative hospital stay was 11.4 days. Donor site seroma was reported in four cases and managed by office aspiration and compressive dressing. Postoperative scarring, donor site deformity, and the overall shape of the neobreast were acceptable, scoring above 7.

Conclusions

Replacement of 20% to 40% of breast volume in the upper and the lower outer quadrants with a latissimus dorsi muscle flap by using endoscopic harvesting is a good alternative reconstruction technique after partial mastectomy. Short incision benefits from a very acceptable postoperative scar, less pain, and early upper extremity movement.
