Robotic-assisted harvest of latissimus dorsi muscle flap for breast reconstruction: review of the literature

Endoscopic-Assisted Latissimus Dorsi Muscle Flap for Chest Wall Reconstruction in Poland Syndrome: Clinical Application and Literature Review

BACKGROUND

Poland syndrome is a rare congenital chest wall developmental defect. Traditional reconstruction applies open to harvest of the latissimus dorsi muscle flap, but issues like large incisions and high complication rates exist. Endoscopic-assisted harvest of the latissimus dorsi muscle flap has minimally invasive advantages worth exploring for application in Poland syndrome patients.

METHODS

We retrospectively analyzed the surgical situations of five Poland syndrome patients at our center, and systematically searched the literature, including 31 cases of endoscopic-assisted latissimus dorsi muscle flap reconstruction. Data on surgical complications, postoperative shoulder function scores, aesthetic scores, and patient satisfaction were collected and comprehensively analyzed in combination with literature reports.

RESULTS

Endoscopic surgery had smaller incisions, fewer complications, shorter recovery time, and high patient scar satisfaction. Postoperative aesthetic results were good, but the obtained flap tissue volume was limited. Upper limb function at the donor site was preserved, but there was some degree of strength decline.

CONCLUSIONS

Endoscopic-assisted latissimus dorsi flap surgery (ELDM) allows for clear visualization of the surgical field, reduces complications, minimizes scarring, shortens recovery time, and provides better cosmetic results, making it suitable for young Poland syndrome patients seeking improved aesthetic outcomes.

Minimal Access vs Conventional Nipple-Sparing Mastectomy

Importance

While nipple-sparing mastectomy (NSM) for breast cancer was only performed using the open method in the past, its frequency using endoscopic and robotic surgical instruments has been increasing rapidly. However, there are limited studies regarding postoperative complications and the benefits and drawbacks of minimal access NSM (M-NSM) compared with conventional NSM (C-NSM).

Objective

To examine the differences in postoperative complications between C-NSM and M-NSM.

Design, Setting, Participants

This was a retrospective multicenter cohort study enrolling 1583 female patients aged 19 years and older with breast cancer who underwent NSM at 21 university hospitals in Korea between January 2018 and December 2020. Those with mastectomy without preserving the nipple-areolar complex (NAC), clinical or pathological malignancy in the NAC, inflammatory breast cancer, breast cancer infiltrating the chest wall or skin, metastatic breast cancer, or insufficient medical records were excluded. Data were analyzed from November 2021 to March 2024.

Exposures

M-NSM or C-NSM.

Main Outcomes and Measures

Clinicopathological factors and postoperative complications within 3 months of surgery were assessed. Statistical analyses, including logistic regression, were used to identify the factors associated with complications.

Results

There were 1356 individuals (mean [SD] age, 45.47 [8.56] years) undergoing C-NSM and 227 (mean [SD] age, 45.41 [7.99] years) undergoing M-NSM (35 endoscopy assisted and 192 robot assisted). There was no significant difference between the 2 groups regarding short- and long-term postoperative complications (<30 days: C-NSM, 465 of 1356 [34.29%] vs M-NSM, 73 of 227 [32.16%]; P = .53; <90 days: C-NSM, 525 of 1356 [38.72%] vs M-NSM, 73 of 227 [32.16%]; P = .06). Nipple-areolar complex necrosis was more common in the long term after C-NSM than M-NSM (C-NSM, 91 of 1356 [6.71%] vs M-NSM, 5 of 227 [2.20%]; P = .04). Wound infection occurred more frequently after M-NSM (C-NSM, 58 of 1356 [4.28%] vs M-NSM, 18 of 227 [7.93%]; P = .03). Postoperative seroma occurred more frequently after C-NSM (C-NSM, 193 of 1356 [14.23%] vs M-NSM, 21 of 227 [9.25%]; P = .04). Mild or severe breast ptosis was a significant risk factor for nipple or areolar necrosis (odds ratio [OR], 4.75; 95% CI, 1.66-13.60; P = .004 and OR, 8.78; 95% CI, 1.88-41.02; P = .006, respectively). Conversely, use of a midaxillary, anterior axillary, or axillary incision was associated with a lower risk of necrosis (OR for other incisions, 32.72; 95% CI, 2.11-508.36; P = .01). Necrosis occurred significantly less often in direct-to-implant breast reconstruction compared to other breast reconstructions (OR, 2.85; 95% CI, 1.11-7.34; P = .03).

Conclusions and Relevance

The similar complication rates between C-NSM and M-NSM demonstrates that both methods were equally safe, allowing the choice to be guided by patient preferences and specific needs.

Ushering in the era of regenerative surgery

Tissue loss, irrespective of etiology, often requires extensive reconstruction. In many instances, the need exceeds what current treatments and technologies modern medicine can offer. Tissue engineering has made immense strides within the past few decades due to advances in biologics, biomaterials, and manufacturing. The convergence of these three domains has created limitless potential for future surgical care. Unfortunately, there still exists a disconnect on how to best implant these 'replacement parts' and care for the patient. It is therefore vital to develop paradigms for the integration of advanced surgical and tissue engineering technologies. This paper explores the convergence between tissue engineering and reconstructive surgery. We will describe the clinical problem of tissue loss, discuss currently available solutions, address limitations, and propose processes for integrating surgery and tissue engineering, thereby ushering in the era of regenerative surgery.

Bibliometric analysis of robotic surgery research in breast cancer conducted between 2008 and 2022

BACKGROUND

To carry out a bibliometric analysis of robotic surgery research in the field of breast cancer conducted between 2008 and 2022 and to evaluate the status and trends in the field.

METHODS

A systematic search was undertaken in the Web of Science (WoS) for published articles related to surgical robots and breast cancer. R and VOSviewer software were used to carry out a quantitative analysis to explore the trend of annual publication volume and the cooperative relationship between countries, institutions, authors, and keywords.

RESULTS

A total of 177 publications were retrieved, 79.66% of which were published from 2016 to 2022, and most were conducted in the United States (US), China, and South Korea. Articles from the US had the most frequent international cooperation. A tally of institutional publications showed that Yonsei University (YONSEI UNIV; Korea) had produced the most publications. The author with the most published papers was Lee of YONSEI UNIV. The most accepted journal was the Asian Journal of Surgery. Keyword co-occurrence analysis showed that current research hotspots were mainly focused on nipple-conserving mastectomy and breast reconstruction, and breast-conserving and nipple-conserving mastectomy may be future research hotspots.

CONCLUSIONS

The annual incidence of robotic surgery and breast cancer is gradually increasing. The predominant countries conducting research in this field include the US, China, and South Korea, and the institutions are mainly distributed in universities and hospitals. Nipple-conserving mastectomy and breast reconstruction may be the current research hotspots, and breast-conserving mastectomy and minimally invasive surgery may represent hot research areas in the future. These findings may help scholars who are committed to the application of surgical robots to breast cancer to better understand the current research status and trends.

Breast Reconstruction: Necessity for Further Standardization of the Current Surgical Techniques Attempting to Facilitate Scientific Evaluation and Select Tailored Individualized Procedures Optimizing Patient Satisfaction

Background

Various breast cancer reconstruction methods and novel surgical techniques include autologous or allogenic procedures, which can increase patient's quality of life and provide options when dealing with patients seen as challenging clinical scenarios.

Summary

Our aim was to review the current literature and present published evidence on innovative standards in whole breast reconstruction. Advances in flap monitoring or newly published data regarding neurotization in breast reconstruction, arm lymphedema management, breast implant-associated anaplastic large cell lymphoma reconstruction treatment, and robotic surgery with regard to radiotherapy define innovative standards in the breast reconstruction setting. The role of meshes/acellular dermal matrix and fat grafting as well as optimal sequencing of postmastectomy radiotherapy in autologous and alloplastic breast reconstruction appear highly debatable also in expert panel meetings rendering further clinical research including RCTs imperative.

Key Messages

There is an abundance of novel available techniques, which mandate further standardization, facilitating scientific evaluation in an attempt to help surgeons select tailored procedures for each patient with the goal to promote informed decision-making in breast reconstruction.
