Video-assisted Transaxillary Nipple-sparing Mastectomy and Immediate Implant-based Breast Reconstruction: A Novel and Promising Method

A Novel Endoscopic Approach for Treating Breast Cancer: Haigui-1 Hole

OBJECTIVE

Endoscopic surgery is an effective technique for preserving the nipple and areola, as well as for sentinel lymph node biopsy and breast implant reconstruction. However, the technical challenges associated with endoscopic surgery have limited its widespread adoption.

METHODS

In the normal single-port endoscopic surgery, the ultrasonic knife was accessed through the retractor. In our modified procedure, a tiny 5 mm incision was made at the lateral margin underneath the breast, serving as the second entry port for the ultrasonic scalpel, which was referred to as the "Haigui-1 hole". Preoperative and postoperative indicators such as blood loss, operative time, and postoperative drainage volume were collected. Differences between parameters were compared using Student's t test.

RESULTS

Endoscopic surgery with the assistance of the "Haigui-1 hole" led to preserved breast aesthetics with minimal scarring. Moreover, "Haigui-1 hole" surgery significantly reduced the operation time, intraoperative bleeding, and postoperative drainage volume compared to normal single-port endoscopic surgery.

CONCLUSION

The "Haigui-1 hole" procedure, which involves the addition of a second entrance to improve the maneuverability of the ultrasonic knife, is worthy of further promotion.

Clinical Outcomes of Transaxillary Reverse-Sequence Endoscopic Nipple-Sparing Mastectomy and Direct-to-Implant Prepectoral Breast Reconstruction: A Prospective Study of Initial 68 Procedures

BACKGROUND

Minimal access breast surgery improves cosmetic outcomes over conventional breast surgery but still faces barriers in becoming standard procedure for breast reconstruction. This report introduces a novel technique of transaxillary reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) followed by direct-to-implant prepectoral breast reconstruction (DTI-PBR) and describes its clinical outcomes.

METHODS

This prospective study enrolled patients who underwent R-E-NSM and DTI-PBR from March 2021 to December 2021 at a single institution. Perioperative data, surgical complications, oncologic outcomes, and patient- and surgeon-reported cosmetic results were noted.

RESULTS

The 60 patients in this study who underwent 68 R-E-NSM and DTI-PBR had a mean age was 40.4 ± 10.3 years. The average durations of uni- and bilateral operations were 156.5 ± 48.3 min and 191.3 ± 36.1 min, respectively. The overall surgical complication rate was 13.3%, including 10.0% of patients with minor complications and 3.3% of patients with major complications. The study had one case (1.7%) of implant loss and one case (1.7%) of skin flap necrosis treated by reoperation. During the median follow-up period of 24 months, one patient (1.7%) who discontinued chemotherapy for myelosuppression experienced liver metastases 5 months postoperatively, and one patient experienced new-onset contralateral ductal carcinoma in situ 24 months postoperatively. The preoperative and 18-month postoperative Breast-Q scores for satisfaction with breasts, psychosocial well-being, sexual well-being, and chest well-being did not differ significantly, and the Scar-Q was 81.2 ± 14.5 points. The good-to-excellent rate in surgeon-reported cosmetic results reached 90%.

CONCLUSIONS

Transaxillary R-E-NSM followed by DTI-PBR is a safe and efficient technique with high cosmetic outcomes and reliable medium-term oncologic results.

Reverse-sequence endoscopic nipple-sparing mastectomy with immediate implant-based breast reconstruction: an improvement of conventional minimal access breast surgery

Background

Our center proposes a new technique that effectively provides space to broaden the surgical field of view and overcomes the limitations of endoscopy-assisted nipple-sparing mastectomy (E-NSM) by changing the dissection sequence and combining it with air inflation. The purpose of this study was to compare the clinical outcomes of the new technique designated "reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with subpectoral breast reconstruction (SBR)" and the conventional E-NSM (C-E-NSM) with SBR.

Method

All patients undergoing E-NSM with SBR at our breast center between April 2017 and December 2022 were included in this study. The cohort was divided into the C-E-NSM group and the R-E-NSM group. The operation time, anesthesia time, medical cost, complications, cosmetic outcomes, and oncological safety were compared.

Results

Twenty-six and seventy-nine consecutive patients were included in the C-E-NSM and R-E-NSM groups, with average ages of 36.9 ± 7.0 years and 39.7 ± 8.4 years (P=0.128). Patients in the R-E-NSM group had significantly shorter operation time (204.6 ± 59.2 vs. 318.9 ± 75.5 minutes, p<0.001) and anesthesia time (279.4 ± 83.9 vs. 408.9 ± 87.4 minutes, p<0.001) and decreased medical costs [5063.4 (4439.6-6532.3) vs. 6404.2 (5152.5-7981.5), USD, p=0.001] and increase SCAR-Q scores (77.2 ± 17.1 vs. 68.8 ± 8.7, P=0.002) compared to the C-E-NSM group. Although trends increased in both the excellent rate of Ueda scores (53.8% vs. 42.3%, P = 0.144), excellent rate of Harris scores (44.0% vs. 63.1%, P=0.102), and decreased surgical complications (7.6% vs. 19.2%, P = 0.135) were observed in the R-E-NSM group, the differences were not significant. There were no significant differences in oncological outcomes between the two groups.

Conclusion

R-E-NSM improves cosmetic outcomes and efficiency of C-E-NSM, reduces medical costs, and has a trend of lower surgical complications while maintaining the safety of oncology. It is a safe and feasible option for oncological procedures that deserves to be promoted and widely adopted in practice.

A novel technique of reverse-sequence endoscopic nipple-sparing mastectomy with direct-to-implant breast reconstruction: medium-term oncological safety outcomes and feasibility of 24-hour discharge for breast cancer patients

BACKGROUND

Due to the short operation time and no need for special instruments, reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with direct-to-implant breast reconstruction (DIBR) has been rapidly becoming popular in the last three years. However, there has yet to be an evaluation of its oncologic safety or the feasibility of discharging patients within 24 hours.

MATERIALS AND METHODS

In this single-center retrospective cohort study, individuals diagnosed with stage 0-III breast cancer between May 2020 and April 2022 who underwent traditional open mastectomy or R-E-NSM with DIBR were included. Follow-up started on the date of surgery and ended in December 2023. Data, including demographics, tumor characteristics, medium-term oncological outcomes, and postoperative complications, were collected and analyzed. Propensity score matching (PSM) was performed to minimize selection bias.

RESULTS

This study included 1679 patients (median [IQR] age, 50 [44-57] years). Of these, 344 patients underwent R-E-NSM with DIBR (RE-R group), and 1335 patients underwent traditional open mastectomy (TOM group). The median [IQR] follow-up time was 30 [24-36] months (29 [23-33] months in the RE-R group and 30 [24-36] months in the TOM group). Regarding before or after PSM, the P value of local recurrence-free survival (LRFS, 0.910 and 0.450), regional recurrence-free survival (RRFS, 0.780 and 0.620), distant metastasis-free survival (DMFS, 0.061 and 0.130), overall survival (OS, 0.260 and 0.620), disease-free survival (DFS, 0.120 and 0.330) were not significantly different between the RE-R group and the TOM group. The 3y-LRFS and 3y-DFS rates were 99.0% and 97.1% for the RE-R group and 99.5% and 95.3% for the TOM group, respectively. The rates of any complications and major complications were not significantly different between the RE-R patients who were discharged within 24 hours and the RE-R patients who were not discharged within 24 hours (P=0.290, P=0.665, respectively) or the TOM patients who were discharged within 24 hours (P =0.133, P=0.136, respectively).

CONCLUSIONS

R-E-NSM with DIBR is an innovative oncologic surgical procedure that not only improves cosmetic outcomes but also ensures reliable oncologic safety and fewer complications, enabling patients to be safely discharged within 24 hours. A long-term prospective multicenter assessment will be supporting.

Minimally Invasive and Innovative Management of Prosthesis Infections in Endoscopic-Assisted Breast Reconstruction

BACKGROUND

Implant infection continues to be the most common complication of breast reconstruction, and it can lead to serious consequences of implant loss. Recently, endoscopic-assisted nipple-sparing mastectomy with direct-to-implant breast reconstruction is being performed more frequently, with similar prosthetic infection incidence compared to conventional techniques. But there is little information published in the literature on the management of periprosthetic infection in endoscopic-assisted breast reconstruction.

METHODS

A retrospective review was performed of patients who underwent endoscope-assisted breast reconstruction and developed periprosthetic infection between January 2020 and December 2022. Prosthesis infection was defined as any case where antibiotics were given, beyond the surgeon's standard perioperative period, in response to clinical signs such as swelling, pain, erythema, increased temperature, fever, etc. We summarized our clinical approach and treatment protocol for periprosthetic infection patients. Collected data include preoperative basic information, surgical details, postoperative data, and outcomes.

RESULTS

A total of 580 patients (713 reconstructions) underwent endoscopic-assisted immediate breast reconstruction. There were 58 patients developed periprosthetic infection, 14 of whom had bilateral prosthesis reconstruction with unilateral prosthesis infection. The incidence of infection was 10.0%. Average follow-up was 17.3 ± 8.9 months (range = 2-37 months). Of the 58 patients, 53 (91.4%) patients successful salvaged implant and 5(8.6%) patients removed prosthesis. During follow-up, Baker III capsular contracture occurred in 2 patients (3.8%) who had radiotherapy.

CONCLUSION

Our management of prosthesis infections in endoscopic-assisted breast reconstruction is easy, minimally invasive, and inexpensive. This method can be repeated if the implant infection does not improve after the first drainage. What's more, our data suggest that our prosthesis salvage of periprosthetic infection is effective.

Gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI) for breast cancer: Lei's five-step method

Background

Endoscopic nipple-sparing mastectomy (E-NSM) is a promising procedure in the treatment of breast cancer, but the limitations of endoscopic tools and intrinsic technical complexity of the technique hinder its applicability. Here, we introduce a novel surgery, gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI), for breast cancer. and early effects.

Methods

A retrospective analysis of the clinical data of 11 female patients, aged 50 (27-78) years, admitted to our hospital from January to December 2022, who underwent gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI), was conducted. This study was designed to assess patient satisfaction before and after breast reconstruction, early complications, and breast function.

Results

The tumors were all solitary, with a mean maximum diameter of 1.0 (0-2.0) cm and a mean distance of 2.3 (2-4) cm from the nipple, the mean intraoperative bleeding volume was 47.5 mL, and the mean hospital stay was 1.5 d. Postoperatively, 1 patient developed depigmentation of the nipple due to mild ischemia. There were no incisional complications, subcutaneous emphysema, infection, areola necrosis, skin flap necrosis, or removal of the prosthesis and/or patch. No tumor recurrence or metastasis was observed during the follow-up period. The difference between breast satisfaction and psychosocial health scores was not statistically significant (P = 0.680; P = 0.612).

Conclusion

GETSMIRI, immediate implantable breast reconstruction, is less invasive than other such procedures, and short-term follow-up results show good postoperative satisfaction, making it an alternative surgical method.

Transaxillary Single-Port Endoscopic Nipple-Sparing Mastectomy with Immediate Implant-based Breast Reconstruction in Breast Cancer Patients Receiving Neoadjuvant Chemotherapy or Not: A Comparative Study with Analysis of Surgical Complications and Patient-Reported Outcomes

BACKGROUND

In most cases, transaxillary single-port endoscopic nipple-sparing mastectomy with immediate implant-based breast reconstruction (E-NSM-IIBR) is conducted in patients with early-stage breast cancer, ensuring surgical safety while achieving improved breast aesthetics. However, whether E-NSM-IIBR is appropriate in patients undergoing neoadjuvant chemotherapy (NAC) is still unclear. The aim of this study was to report the surgical safety and patient-reported outcomes (PROs) of breast cancer patients who underwent E-NSM-IIBR with NAC in comparison to those who did not receive NAC.

METHODS

A retrospective cohort study was conducted on patients who underwent E-NSM-IIBR with or without NAC at a single center between January 2021 and July 2022. Patient demographics, postoperative complications, and PROs evaluated using the BREAST-Q version 2.0 questionnaire were compared between the two groups. Factors associated with PROs at 9 months after surgery were assessed with linear regression analysis.

RESULTS

A total of 92 patients who underwent E-NSM-IIBR were included in the study, with 27 patients receiving NAC and 65 patients not receiving NAC. There was no significant difference in the incidence of postoperative complications between the two groups. The BREAST-Q version 2.0 questionnaire was completed by 24 out of 27 patients (88.9%) in the NAC group and 59 out of 65 patients (90.8%) in the non-NAC group at 9 months after surgery. The patient-reported outcomes in various domains of the BREAST-Q did not show a significant difference between the two cohorts. The results of the multiple linear regression analysis indicated that in the both groups age (β = - 0.985, 95% CI - 1.598 to - 0.371, p = 0.003 in the NAC group; β = - 0.510, - 1.011 to - 0.009, p = 0.046 in the non-NAC group) and rippling (β = - 21.862, - 36.768 to - 6.955, p = 0.006 in the NAC group; β = - 7.787, - 15.151 to - 0.423, p = 0.039 in the non-NAC group) significantly impacted the patients' satisfaction with breasts, and PMRT was negatively associated with patients' physical well-being of chest (β = - 13.813, - 26.962 to - 0.664, p = 0.040 in the NAC group; β = - 18.574, - 30.661 to - 6.487, p = 0.003 in the non-NAC group). Our findings revealed that patients with larger implant volumes had higher scores in psychosocial well-being (β = 0.082, 0.001 to 0.162, p = 0.047), whereas implant displacement (β = - 14.937, - 28.175 to - 1.700, p=0.028) had a negative impact on patients' psychological well-being in the non-NAC group. However, our results did not demonstrate any significant influencing factors on patients' psychosocial well-being within the NAC group.

CONCLUSION

Our preliminary experiences confirm that E-NSM-IIBR is a safe option for selected patients even after NAC, with favorable patient-reported outcomes comparable with those in the primary surgery setting. The postoperative long-term outcomes of patients who undergo radiation therapy after NAC merit further investigation in the future.

Single Axillary Incision Reverse Sequence Endoscopic Nipple-Sparing Mastectomy in the Management of Gynecomastia: Short-Term Cosmetic Outcomes, Surgical Safety, and Learning Curve of the Preliminary 156 Consecutive Procedures from a Prospective Cohort Study

BACKGROUND

Currently, a standard, optimal surgical procedure is still lacking for gynecomastia. Despite the development of a variety of surgical interventions, these techniques were often limited to patients with Simon I and II. The present study aimed to introduce a novel technique for all types and grades of gynecomastia, and reported the preliminary results.

METHODS

Patients who received single axillary incision reverse sequence endoscopic nipple-sparing mastectomy (R-E-NSM) from March 2021 to March 2023 were enrolled at a single institution. The data from 3-month follow-up cut-off were collected prospectively and analyzed to determine the short-term esthetic and safety results of this technique, as well as the learning curve.

RESULTS

A total of 159 single axillary incision reverse sequence endoscopic nipple-sparing mastectomy procedures were performed in 81 gynecomastia patients. Among these 81 patients, 7 patients (8.6%) were classified as Simon grade I, 29 patients (35.8%) as grade IIa, 24 patients (29.6%) as grade IIb, and 21 patients (25.9%) as grade III. In the patient-reported cosmetic results, the overall satisfaction score was 8.4 ± 1.4. A total of 74.1% of patients were highly satisfied, and 25.9% were satisfied. The overall complication rate was 10.1%, and only 1 patient had a major complication. According to the cumulative sum plot analysis, approximately 12 cases were needed for surgeon B and 11 cases for surgeon C to decrease their operation time significantly.

CONCLUSIONS

R-E-NSM is safe and effective for all Simon grade gynecomastia patients, with excellent cosmetic results and a short learning curve. However, a long-term follow-up assessment is still needed.

Single axillary incision reverse-order endoscopic nipple/skin-sparing mastectomy followed by subpectoral implant-based breast reconstruction: Technique, clinical outcomes, and aesthetic results from 88 preliminary procedures

BACKGROUND

Single axillary incision reverse-order endoscopic nipple-sparing mastectomy overcomes the limitations of conventional endoscopic nipple-sparing mastectomy application. We introduce this technique and report the preliminary results of this study.

METHODS

Patients who received single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy from May 2020 to May 2022 were enrolled from a single institution. Data were analyzed to evaluate the safety and effectiveness of this technique. Patient-reported and surgeon-reported cosmetic outcomes were collected.

RESULTS

In total, 68 patients who underwent 88 single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy combined with subpectoral implant-based breast reconstruction were enrolled in the current study. The overall complication rate was 10.3%. In total, 2.9% of patients suffered from major complications, and 5 (7.4%) experienced minor complications. Only 1 patient experienced partial nipple-areola complex necrosis. During a median follow-up time of 24 months, the locoregional recurrence and distant metastasis rate was both 1.6%. In the surgeon-reported cosmetic results, 92.1% of patients achieved good or excellent results. The mean SCAR-Q scores were 82.07 ± 8.86, and 85.3% evaluated their breasts as good or excellent. The mean overall cost was 5,670.4 ± 1,351.3 USD. The total mean operation time and maturity-stage mean operation time were 234.3 ± 80.4 and 172.55 ± 41.29 min, respectively. According to cumulative sum plot analysis, approximately 18 cases were needed for surgeons to decrease their operation time significantly and complication rate.

CONCLUSION

Single axillary incision reverse-order endoscopic nipple-sparing mastectomy is a safe, less expensive, and efficient surgical technique with reliable intermediate-term oncologic safety. For suitable candidates, the technique with subpectoral implant-based breast reconstruction can provide a good cosmetic outcome.

Short-term safety and cosmetic outcomes of endoscopic direct-to-implant breast reconstruction and simultaneous contralateral breast augmentation for breast cancer: a prospective analysis of 33 patients

BACKGROUND

For patients with small breasts, breast-conserving surgery (BCS) and unilateral nipple-/skin-sparing mastectomy (N/SSM) with breast reconstruction may result in visible breast deformities or asymmetry, and contralateral breast augmentation often require a two-staged operation. We propose a novel endoscopic technique, direct-to-implant breast reconstruction and simultaneous contralateral breast augmentation (DTI-BR-SCBA), and report its short-term safety and cosmetic outcomes.

METHODS

In this prospective study, patients with early breast cancer who underwent endoscopic DTI-BR-SCBA between November 2020 and August 2022 were followed for more than 3 months to analysed short-term postoperative safety (complications and oncological safety) and cosmetic outcomes (doctor-assessed results by Ueda scale and patient-reported results by Breast-Q scale).

RESULTS

A total of 33 patients, including 30 treated with endoscopic prepectoral DTI-BR-SCBA, 1 with endoscopic dual-plane DTI-BR-SCBA and 2 with endoscopic subpectoral DTI-BR-SCBA, were analysed. The mean age was 39.7 ± 6.7 years. The mean operation time was 165.1 ± 36.1 min. The overall surgical complication rate was 18.2%. All complications were minor, including haemorrhage (3.0%), cured by compression haemostasis, surgical site infection (9.1%), cured by oral antibiotics, and self-healing nipple-areolar complex ischaemia (6.1%). Furthermore, rippling and implant edge visibility occurred in 6.2% of them. The outcome was graded as "Excellent" and "Good" in 87.9% and 12.1% of patients in the doctor cosmetic assessment, respectively, and patient satisfaction with breasts was significantly improved (55.0 ± 9.5 vs. 58.8 ± 7.9, P = 0.046).

CONCLUSIONS

The novel endoscopic DTI-BR-SCBA method may be an ideal alternative for patients with small breasts because it can improve cosmetic results with a relatively low complications rate, which makes it worthy of clinical promotion.

Trans-axillary single port insufflation technique-assisted endoscopic surgery for breast diseases: Clinic experience, cosmetic outcome and oncologic result

Purpose

With an increasing demand for postoperative cosmetic effects in breast diseases, the single port by trans-axillary incision and air-inflation system, which provided better space and spared the assistant the effort of retraction, is widely used in clinic surgical treatment for multiple breast diseases.

Methods

According to inclusion and exclusion criteria, patients who underwent trans-axillary single-incision surgery at Tianjin Medical University Cancer Hospital between December 2020 and July 2022 were included in the study. We collected and analyzed data on age, fertility history, ultrasound grade, clinical stage, pathological results, oncological prognosis, patient-centered cosmetic outcome, etc.

Results

A total of 115 cases were included, of which 33 patients with benign disease underwent mass resection, 68 patients with malignant tumors underwent mastectomy. 10 patients had a special type of breast lesion. A mastectomy was performed in 4 patients with male mammary gland development. Of the 115 cases, the maximum mass diameter was 3.00 ± 1.644 (0.6–8.5) cm. Blood loss during surgery was 85.77 ± 50.342 (10-200) ml. The surgery took 131.84 ± 59.332 (30-280) minutes to complete. The patient spent a total of 5.05 ± 2.305 (2-18) days in the hospital. And the length of surgical incision in all patients was 3.83 ± 0.884 (3-8) cm. All patients were very satisfied with the appearance of their breasts after dressing. 94.78% of patients were satisfied with the position of the incision.

Conclusion

Through this study, we believe that in benign breast diseases and malignant breast tumors, trans-axillary single port insufflation technique-assisted endoscopic surgery has oncological safety and an aesthetic effect for most people with breast diseases.

A Preliminary Experience of Endoscopic Total Mastectomy With Immediate Free Abdominal-Based Perforator Flap Reconstruction Using Minimal Incisions, and Literature Review

PURPOSE

Endoscopic total mastectomy (ETM) is predominantly performed with reconstruction using prostheses, lipofilling, omental flaps, latissimus dorsi flaps, or a combination of these techniques. Common approaches include minimal incisions, e.g., periareolar, inframammary, axillary, or mid-axillary line, which limit the technical ability to perform autologous flap insets and microvascular anastomoses, as such the ETM with free abdominal-based perforator flap reconstruction has not been robustly explored.

METHODS

We studied female patients with breast cancer who underwent ETM and abdominal-based flap reconstruction. Clinical-radiological-pathological characteristics, surgery, complications, recurrence rates, and aesthetic outcomes were reviewed.

RESULTS

Twelve patients underwent ETM with abdominal-based flap reconstruction. The mean age was 53.4 years (range 36-65). Of the patients, 33.3% were surgically treated for stage I, 58.4% for stage II, and 8.3% for stage III cancer. Mean tumor size was 35.4 mm (range 1-67). Mean specimen weight was 458.75 g (range 242-800). Of the patients, 92.3% successfully received endoscopic nipple-sparing mastectomy and 7.7% underwent intraoperative conversion to skin-sparing mastectomy after carcinoma was reported on frozen section of the nipple base. Mean operative time for ETM was 139 minutes (92-198), and the average ischemic time was 37.3 minutes (range 22-50). Fifty percent of patients underwent deep inferior epigastric perforator, 33.4% underwent MS-2 transverse rectus abdominis musculocutaneous (TRAM), 8.3% underwent MS-1 TRAM, and 8.3% underwent pedicled TRAM flap reconstruction. No cases required re-exploration, no flap failure occurred, margins were clear, and no skin or nipple-areolar complex ischemia/necrosis developed. In the aesthetic outcome evaluation, 16.7% were excellent, 75% good, 8.3% fair, and none were unsatisfactory. No recurrences were observed.

CONCLUSION

ETM through a minimal-access inferior mammary or mid-axillary line approach, followed by immediate pedicled TRAM or free abdominal-based perforator flap reconstruction, can be a safe means of achieving an "aesthetically scarless" mastectomy and reconstruction through minimal incisions.

Endoscopic Nipple- or Skin-Sparing Mastectomy and Immediate Breast Reconstruction with Endoscopic Harvesting of the Latissimus Dorsi Flap: A Preliminary Experience of an Innovative Technique

Background

Endoscopic nipple- or skin-sparing mastectomy (E-N/SSM) and endoscopic latissimus dorsi muscle flap (E-LDMF) harvest have been operational difficulties over decades. The aim of this study was to describe the preliminary outcomes of our novel surgical technique, which allows the performance of E-N/SSM and E-LDMF harvest for immediate breast reconstruction (IBR) through a single cosmetic axillary incision for breast cancer patients.

Methods

This prospective study included 20 breast cancer patients who underwent E-N/SSM and E-LDMF harvesting through a single axillary incision in our hospital from September 2020 to June 2022. The outcomes were statistically calculated, including patient characteristics, operative data, complication rate, hospital length of stay and costs, and patient-reported outcomes.

Results

A total of 20 breast cancer patients underwent our sufficiently mature novel endoscopy technique. The mean LD flap harvest time was 96.5 ± 25.3 min, the mean operation time was 262.6 ± 54.4 min, and the average length of LDMF was 26.9 ± 3.1. During the median follow-up time of 7.5 months, 4 patients developed donor-site seroma. One of them was also complicated by hypopigmentation of the nipple areola, and one of them suffered from breast cellulitis. No bleeding or flap necrosis happened. No tumor recurrence or metastasis was found until the last follow-up. In the BREAST-Q evaluation, although they gave a lower score beginning at 1-month post-operation than preoperatively (P > 0.05, except for physical well-being: chest and physical well-being: back and shoulder, P < 0.01), there was an uptrend at 3 months postoperatively. Because of the hidden and short incision, the mean score of the appearance scale of the SCAR-Q at 3 months post-operation was 74.2 ± 8.8.

Conclusions

The novel endoscopy technique, which was first reported to perform lymph node surgery, N/SSM, and LDMF harvesting in an operation for breast cancer patients through a single axillary incision, is associated with a shorter surgery time, lower complication rates, and better patient-reported outcomes.
