Chest wall reconstruction after extended resection

Sternal Resections: An Attempt to Find the Ideal Reconstruction Method

Background and Objectives: Sternal resections, although rare, pose significant challenges for the reconstruction of large anterior chest wall defects. Both stability and soft tissue reconstruction are essential for preventing respiratory complications and ensure structural stability. Despite the variety of techniques proposed, no consensus exists on an optimal method. Herein, we present our institutional experience using the novel "spider-web" technique combined with an anterolateral thigh (ALT) free flap for chest wall and soft tissue reconstruction following extensive sternectomies. Materials and Methods: Between January 2023 and November 2024, five female patients underwent partial or total sternectomy for oncologic indications. Chest wall stability was restored using the "spider-web" technique-based on non-resorbable polyester threads arranged in a geometric web pattern reinforced with polypropylene mesh-followed by soft tissue reconstruction using a free ALT myocutaneous flap. Data on demographics, surgical details, postoperative outcomes, and complications were prospectively analyzed. Results: Resections included two partial and three total sternectomies. The mean operative time was 385 min (range: 330-435 min). All patients were extubated postoperatively without the need for respiratory support. The "spider-web" construct provided adequate chest wall stability with no cases of paradoxical movement or chronic pain. No flap loss occurred; one case required revision for venous thrombosis, and one hematoma at the donor site was evacuated. No infections or wound dehiscence were observed. The median hospital stay was 11 days (SD ± 1.67 days), and 30-day mortality was 0%. Median follow-up was 10 months (SD ± 6.55 months), without long-term complications. Conclusions: The "spider-web" technique, combined with ALT myocutaneous free flap, is a simple, reliable, and cost-effective method for the reconstructing extensive chest wall defects following sternectomy. Its technical versatility and favorable outcomes suggest it as a valuable option, offering both structural stability and soft tissue coverage with minimal morbidity.

Long-Term Outcome of Chest Wall and Diaphragm Repair with Biological Materials

INTRODUCTION

 Chest wall and/or diaphragm reconstruction aims to preserve, restore, or improve respiratory function; conserve anatomical cavities; and upkeep postural and upper extremity support. This can be achieved by utilizing a wide range of different grafts made of synthetic, biological, autologous, or bioartificial materials. We aim to review our experience with decellularized bovine pericardium as graft in the past decade.

PATIENTS AND METHODS

 We conducted a retrospective analysis of patients who underwent surgical chest wall and/or diaphragm repair with decellularized bovine pericardium between January 1, 2012 and January 13, 2022 at our institution. All records were screened for patient characteristics, intra-/postoperative complications, chest tube and analgesic therapy duration, length of hospital stay, presence or absence of redo procedures, as well as morbidity and 30-day mortality. We then looked for correlations between implanted graft size and postoperative complications and gathered further follow-up information at least 2 months after surgery.

RESULTS

 A total of 71 patients either underwent isolated chest wall (n = 51), diaphragm (n = 12), or pericardial (n = 4) resection and reconstruction or a combination thereof. No mortality was recorded within the first 30 days. Major morbidity occurred in 12 patients, comprising secondary respiratory failure requiring bronchoscopy and invasive ventilation in 8 patients and secondary infections and delayed wound healing requiring patch removal in 4 patients. There was no correlation between the extensiveness of the procedure and extubation timing (chi-squared test, p = 0.44) or onset of respiratory failure (p = 0.27).

CONCLUSION

 A previously demonstrated general viability of biological materials for various reconstructive procedures appears to be supported by our long-term results.

Five-year experience with titanium mesh for rigid chest wall reconstruction

Objective

To characterize the performance of titanium mesh (TM) (off-label) for rigid chest wall reconstruction at a single institution over a 5-year period.

Methods

Between January 1, 2019, and May 15, 2023, 22 patients (median age, 61 years) underwent chest wall resection with TM reconstruction at Cleveland Clinic. Indications for resection included sarcoma (n = 15), breast cancer (n = 2), lung cancer (n = 2), chondroblastoma (n = 1), and benign neoplasm (n = 2). Patients were followed every 6 months with computed tomography scans for cancer recurrence. Continuous variables are summarized as median (interquartile range [IQR]); categorical variables, as frequency and percentage. Time to mesh fracture was assessed nonparametrically using Kaplan-Meier analysis.

Results

Among the 22 patients over 21,870 patient-days of TM implantation, 21 (95%) had an R0 resection. The mean area of mesh coverage was 108 cm2 (IQR, 97-180 cm2). No patient experienced respiratory complications or mesh failure postoperatively. Of the 3 reoperations (13.6%), 2 were for delayed regional infection (at 7 and 12 months postoperatively), necessitating localized mesh removal, and the third was for local cancer recurrence. Fifteen implants developed visible fractures on imaging at a median time of 9 months after implantation. There were no adverse sequelae, including migration/erosion or clinical decline in respiratory function.

Conclusions

Chest wall resections, particularly those for sarcomas, require large margins for optimal oncologic outcomes. Rigid reconstruction of large defects is desirable, yet options are limited. TM reconstruction provides a promising alternative because of its biocompatibility, rigidity, robust incorporation into surrounding structures, and resistance to infection.

Chest wall resections for advanced breast cancer: a narrative review

Background and Objective

Advanced breast cancer (BC) can involve the chest wall through local invasion by the primary tumor, locoregional recurrence, hematogenous metastasis, or sternum infiltration of the internal mammary chain lymph nodes. The purpose of this article is to review indications and the methods of chest wall resection and reconstruction in patients with advanced BC.

Methods

An online literature search was conducted on PubMed database using the following keywords: "chest wall reconstruction" or "chest wall resection" and "breast cancer". Articles in languages other than English were excluded.

Key Content and Findings

The treatment options should be discussed by a multidisciplinary team. The surgical principles include complete en bloc resection of the tumor including all involved or damaged skin, muscle and part of chest wall including ribs, complete or partial sternum and clavicles, as required, to achieve wide clear margins. The chest wall defect should be reconstructed with a good functional result. The optimal strategy for chest wall reconstruction depends on factors such as the defect`s size, location, and previous radiation or surgical intervention. A part of the reconstruction involves stabilizing the chest wall. Additionally, the defect should be covered with well-vascularized tissue, often necessitating reconstruction with muscle flaps or myocutaneous flaps.

Conclusions

A resection and reconstruction of the chest wall may be the best treatment option to achieve a high quality of life and favorable long-term outcomes, mostly as part of multimodality treatment for highly selected patients.

Chest wall resections for non-small cell lung cancer: a literature review

Background and Objective

The development of early screening for lung cancer has led to improved overall survival in patients with non-small cell lung cancer (NSCLC). However, the management of NSCLC patients with resectable and potentially resectable chest wall invasion (CWI) requires attention. The purpose of this review is to summarize the role of surgery (chest wall resections) in NSCLC patients with CWI.

Methods

A literature search and review from three databases (PubMed, Embase, and ScienceDirect) comprised the last 39 years. This review was focused on the treatment of NSCLC patients with CWI, mainly including the preoperative evaluation, principles of treatment and strategic decision-making, surgical complications, and prognostic factors.

Key Content and Findings

Through the collection of relevant literature on NSCLC that invades the chest wall, this narrative review describes the actual role in clinical practice and future developments of chest wall resections. Preoperative treatment requires the multidisciplinary team (MDT) team to conduct accurate clinical staging of the patient and pay attention to the patient's lymph node status and rib invasion status. The successful implementation of chest wall resection and possible chest wall reconstruction requires refined individualized treatment based on the patient's clinical characteristics, supplemented by possible postoperative systemic treatment.

Conclusions

Surgery plays an important role in treating NSCLC patients with CWI, and a collaborative, experienced MDT is an essential component of the successful treatment of CWI with lung cancer. In the future, more high-quality clinical research is needed to focus on CWI patients so that patients can receive more effective treatment options and better clinical prognosis.

Postoperative Complications of Flap Procedures in Chest Wall Defect Reconstruction: A Two-Center Experience

Background and Objectives: Chest wall defect reconstruction is a complex procedure aimed at restoring thoracic structural integrity after trauma, tumor removal, or congenital issues. In this study, postoperative complications were investigated to improve the care of patients with these critical conditions. Materials and Methods: A retrospective study of chest wall reconstructions from 2004 to 2023 was conducted at Klinikum Nürnberg and Evangelisches Waldkrankenhaus Spandau-Berlin. Data included patient demographics, comorbidities, defect etiology, surgery details, and complications using the Clavien-Dindo classification. Results: Among the 30 patients included in the study, a total of 35 complications occurred in 35 thoracic wall defect reconstructions. These complications were classified into 22 major and 13 minor cases. Major complications were more common in patients with cancer-related defects, and considerable variations were observed between free flap and pedicled flap surgeries. Notably, the use of the anterolateral thigh (ALT) flap with vastus lateralis muscle demonstrated promise, exhibiting fewer complications in select cases. The reconstruction of chest wall defects is associated with substantial complications regardless of the etiology of the defect and the particular surgical procedure used. Interestingly, there was a lower complication rate with free flap surgery than with pedicled flaps. Conclusions: The ALT flap with vastus lateralis muscle deserves further research in this field of reconstruction. Multidisciplinary approaches and informed patient discussions are crucial in this complex surgical field, emphasizing the need for ongoing research and technique refinement.

Microsurgical reconstruction using thoracoacromial vessels as recipients for complicated chest wall defects

BACKGROUND

Free tissue transfer is often required for the reconstruction of complex and deep anterior chest wall wounds, for which the identification of suitable recipient vessels is crucial. Although the internal mammary arteries (IMAs) are a representative option, identifying secondary options when these vessels are compromised remains a challenge. This report evaluated the efficacy of using the thoracoacromial vessels (TAVs) as recipients for chest wall reconstruction by reviewing our experience.

METHODS

We conducted a retrospective review of patients undergoing free-flap-based chest wall reconstruction using TAVs as recipient vessels from February 2020 to March 2023. Patient demographics and surgery-related characteristics data were collected. The primary outcome of interest was the occurrence of flap perfusion-related complications.

RESULTS

In total, 12 cases utilized TAVs as recipients, primarily for defects following sternotomy, where bilateral IMA was unavailable due to prior surgery. The TAVs with reliable perfusion were consistently identified beneath the pectoralis major muscle. The anterolateral thigh flap was predominantly employed, with musculocutaneous or chimeric flaps introduced for bony defects. The mean pedicle length of the harvested flap was 7.2 cm (range, 3-13), and in cases with a vascular gap, the pedicle was extended using an arteriovenous interposition graft. This resulted in a mean pedicle length needed to reach recipient vessels of 9.9 cm (range, 6.5-19). All flaps survived, with only one experiencing partial necrosis.

CONCLUSIONS

The TAV could be considered as an attractive alternative recipient vessel in microsurgical reconstruction of complicated chest wall defects when the use of IMA is not feasible.

Rare case of chondrosarcoma of the manubrium sterni: Management challenges and insights (a surgical case report)

INTRODUCTION AND IMPORTANCE

Chondrosarcoma of the manubrium sterni is an exceedingly rare localization of chondrosarcoma. Its treatment poses a significant therapeutic challenge due to the tumor's proximity to the mediastinal organs and the clavicles. This challenge is magnified when the inner ends need to be resected due to tumor contact with the sternoclavicular joints and, more critically, during the reconstruction of the thoracic wall.

CASE PRESENTATION

We present the case of a 71-year-old female with a 45x42x51 mm chondrosarcoma of the manubrium sterni, extending to both sternoclavicular joints. The diagnosis was confirmed cytologically and histologically after an ultrasound-guided biopsy. A surgical strategy involving en bloc resection of the manubrium sterni, the internal ends of both clavicles, and the first two ribs, followed by sternal reconstruction using a synthetic manubrial plate and titanium costal staples without clavicular bridging, was indicated and executed.

CLINICAL DISCUSSION

This case outlines the surgical considerations and techniques adopted for this complex procedure, emphasizing the operative planning and interdisciplinary collaboration required for a successful outcome.

CONCLUSION

At 18 months post-surgery, the patient demonstrated favorable clinical and radiological progress, indicating a positive response to the treatment strategy employed.

Extended radical resection and chest wall reconstruction for a pulmonary sarcomatoid carcinoma: a case report

BACKGROUND

Pulmonary sarcomatoid carcinoma (PSC) is a rare and highly malignant type of non-small cell lung cancer (NSCLC), for which the treatment of choice is surgery. For peripheral PSC growing outward and invading the chest wall, a complete resection of the affected lung lobes and the invaded chest wall can improve long-term prognosis. However, when the extent of the resected chest wall is large, reconstruction is often required to reduce the risk of postoperative complications. Here, we present a case of PSC invading the chest wall treated with successful extended radical resection for lung cancer and chest wall reconstruction.

CASE PRESENTATION

A 58-year-old male patient with a nodule in the right upper lobe that had been identified on physical examination 2 years before presentation presented to our hospital with a recent cough, expectoration, and chest pain. Imaging revealed a mass in the right upper lobe that had invaded the chest wall. Preoperative puncture pathology revealed poorly differentiated NSCLC. We performed extended radical resection for lung cancer under open surgery and reconstructed the chest wall using stainless steel wire and polypropylene meshes. The procedure was uneventful, and the patient was discharged 7 days postoperatively. Furthermore, the final pathology revealed PSC.

CONCLUSIONS

This case underscores the feasibility of surgical R0 resection in patients with PSC with chest wall invasion and no lymph node metastasis, potentially enhancing long-term outcomes. The novel aspect of this case lies in the individualized chest wall reconstruction for a large defect, using cost-effective materials that offered satisfactory structural support and postoperative recovery, thereby providing a valuable reference for similar future surgical interventions.

Soft tissue reconstruction of the trunk with pedicled perforator and musculocutaneous flaps: A single-center comparative retrospective study

BACKGROUND

Soft tissue trunk reconstruction is often challenging. Although free microvascular flaps are a feasible option in case of extensive defects involving deep structures, pedicled flaps represent a good alternative, especially if harvested and dissected with a "microsurgical" approach. The aim of this study is to evaluate the feasibility of trunk reconstruction with the use of pedicled flaps, according to the application of our reconstructive algorithm, and to compare it to other reconstructive methods.

PATIENTS AND METHODS

From January 2017 to December 2021, we retrospectively analyzed patients who underwent soft tissue reconstruction of the trunk with pedicled flaps at the authors' institution. Patient's demographic, clinical and surgical characteristics and postoperative complications were recorded and analyzed by descriptive statistics. A comparative analysis was made between the study group and two other groups who underwent reconstruction of trunk defects with free flaps and skin grafts, respectively, at the authors' institution.

RESULTS

Forty-seven patients were included in the study. Patients' age ranged between 36 and 82 years (mean: 57.8 years). Twenty-eight patients were male, while 19 patients were female. In 76.6% of patients (36 out of 47), reconstructive procedures were performed to repair defects resulting from cancer resection. Reconstruction of superficial defects was always achieved with perforator flaps (n = 25). In case of full-thickness defects, reconstruction was carried out with musculocutaneous flaps (n = 22); latissimus dorsi and vastus lateralis were the most used flaps for chest and abdominal wall reconstruction, respectively. In our series, we observed only one case of total flap loss requiring re-operation under general anesthesia. Minor complications occurred in 8.5% of cases (4 out of 47 patients). We observed two cases of partial flap necrosis and two cases of wound dehiscence. In the skin grafts group (n = 53), the mean age was 54.5 years (range 39-85) and 56% of patients were male (n = 30). In 66% of cases (n = 30) the defect resulted from oncological resection. The overall complication rate was 18.8% (n = 10). In the free flaps group (n = 10), the mean age was 49.0 years (range 29-77) and 60% of patients (n = 6) were male. In 70% of cases (n = 7) the defect was caused by oncological resection. Complications occurred in two patients (20%). No statistically significant differences were found in terms of overall complication rate between the study group and the two comparative groups (p = .48). A significant correlation was found between the reconstructive method and the type and size of the defect, with reconstruction through free flaps being associated with larger (344.0 vs. 220.4 cm2 ) (p = .04) and full-thickness defects (80.0% vs. 46.8%) (p < .01) if compared to pedicled flaps.

CONCLUSIONS

In the new era of microsurgery, pedicled flaps represent a valid alternative to free flaps for the majority of soft tissue defects of the trunk. In our series, no statistically significant differences in terms of complications were found between reconstructions of similar defects achieved with pedicled and free flaps, and free flap use was limited to extensive full-thickness defects. In addition, the rate of postoperative complications with pedicled flaps found in our cohort was lower than the rate reported in the literature.

Chest wall reconstruction, prosthesis and allografts: a narrative review

Background and Objective

What is the best material in the case of prosthesis used to replace major chest wall resection is still unknown. We reviewed most significant literature focused on the type of prosthetic materials available by highlighting their relative pros and cons.

Methods

We reviewed most significant articles, including clinical results of relevant case series (retrospective studies), published in English in the last 23 years: PubMed, Embase and Scopus databases were used in our search in the period between the 1st January 1999 and 31st December 2022.

Key Content and Findings

Overall, our literature review revealed lack of uniformity or conformity in the surgical strategies described for chest wall reconstruction with no internationally accepted standard in terms of decisions and optimal prosthetic materials and type of prostheses (soft, rigid, biological). Despite the increased interest in chest wall reconstruction, we observed a general lack of substantial prospective and multicentric studies. Likewise, there are not substantial data which may guide to the choice of optimal prosthetics in terms of characteristics and biocompatibility.

Conclusions

A variety of materials are available for reconstruction, including synthetic and biological meshes, flexible and rigid patches, and metal osteosynthesis systems. The material chosen should be optimized to each patient and damaged tissues to be restored. Prospective and multicentric studies are necessary to address current limits in this surgical field.

Reconstructive Strategies in Pediatric Patients after Oncological Chest Wall Resection: A Systematic Review

An appropriate reconstruction strategy after surgical resection of chest wall tumors in children is important to optimize outcomes, but there is no consensus on the ideal approach. The aim of this study was to provide an up-to-date systematic review of the literature for different reconstruction strategies for chest wall defects in patients less than 18 years old. A systematic literature search of the complete available literature was performed and results were analyzed. A total of 22 articles were included in the analysis, which described a total of 130 chest wall reconstructions. All were retrospective analyses, including eight case reports. Reconstructive options were divided into primary closure (n = 21 [16.2%]), use of nonautologous materials (n = 83 [63.8%]), autologous tissue repair (n = 2 [1.5%]), or a combination of the latter two (n = 24 [18.5%]). Quality of evidence was poor, and the results mostly heterogeneous. Reconstruction of chest wall defects can be divided into four major categories, with each category including its own advantages and disadvantages. There is a need for higher quality evidence and guidelines, to be able to report uniformly on treatment outcomes and assess the appropriate reconstruction strategy.

Biologic versus synthetic prosthesis for chest wall reconstruction: a matched analysis

OBJECTIVES

The aim of this study was to compare postoperative outcomes between biologic and synthetic reconstructions after chest wall resection in a matched cohort.

METHODS

All patients who underwent reconstruction after full-thickness chest wall resection from 2000 to 2022 were reviewed and stratified by prosthesis type (biologic or synthetic). Biologic prostheses were of biologic origin or were fully absorbable and incorporable. Integer matching was performed to reduce confounding. The study end point was surgical site complications requiring reoperation. Multivariable analysis was performed to identify associated risk factors.

RESULTS

In total, 438 patients underwent prosthetic chest wall reconstruction (unmatched: biologic, n = 49; synthetic, n = 389; matched: biologic, n = 46; synthetic, n = 46). After matching, the median (interquartile range) defect size was 83 cm2 (50-142) for the biologic group and 90 cm2 (48-146) for the synthetic group (P = 0.97). Myocutaneous flaps were used in 33% of biologic reconstructions (n = 15) and 33% of synthetic reconstructions (n = 15) in the matched cohort (P = 0.99). The incidence of surgical site complications requiring reoperation was not significantly different between biologic and synthetic reconstructions in the unmatched (3 [6%] vs 29 [7%]; P = 0.99) and matched (2 [4%] vs 4 [9%]; P = 0.68) cohorts. On the multivariable analysis, operative time [adjusted odds ratio (aOR) = 1.01, 95% confidence interval (CI), 1.00-1.01; P = 0.006] and operative blood loss (aOR = 1.00, 95% CI, 1.00-1.00]; P = 0.012) were associated with higher rates of surgical site complications requiring reoperation; microvascular free flaps (aOR = 0.03, 95% CI, 0.00-0.42; P = 0.024) were associated with lower rates.

CONCLUSIONS

The incidence of surgical site complications requiring reoperation was not significantly different between biologic and synthetic prostheses in chest wall reconstructions.

Outcome Analysis of Treatment Modalities for Thoracic Sarcomas

BACKGROUND

Primary chest wall sarcomas are a rare and heterogeneous group of chest wall tumors that require multimodal oncologic and surgical therapy. The aim of this study was to review our experience regarding the surgical treatment of chest wall sarcomas, evaluating the short- and long-term results.

METHODS

In this retrospective single-center study, patients who underwent surgery for soft tissue and bone sarcoma of the chest wall between 1999 and 2018 were included. We analyzed the oncologic and surgical outcomes of chest wall resections and reconstructions, assessing overall and recurrence-free survival and the associated clinical factors.

RESULTS

In total, 44 patients underwent chest wall resection for primary chest wall sarcoma, of which 18 (41%) received surgery only, 10 (23%) received additional chemoradiotherapy, 7% (3) received surgery with chemotherapy, and 30% (13) received radiotherapy in addition to surgery. No perioperative mortality occurred. Five-year overall survival was 51.5% (CI 95%: 36.1-73.4%), and median overall survival was 1973 days (CI 95% 1461; -). As determined in the univariate analysis, the presence of metastasis upon admission and tumor grade were significantly associated with shorter survival (p = 0.037 and p < 0.01, respectively). Five-year recurrence-free survival was 71.5% (95% CI 57.6%; 88.7%). Tumor resection margins and metastatic disease upon diagnosis were significantly associated with recurrence-free survival (p < 0.01 and p < 0.01, respectively).

CONCLUSION

Surgical therapy is the cornerstone of the treatment of chest wall sarcomas and can be performed safely. Metastasis and high tumor grade have a negative influence on overall survival, while tumor margins and metastasis have a negative influence on local recurrence.

The contribution of microvascular free flaps and pedicled flaps to successful chest wall surgery

OBJECTIVE

Pedicled flaps (PFs) have historically served as the preferred option for reconstruction of large chest wall defects. More recently, the indications for microvascular-free flaps (MVFFs) have increased, particularly for defects in which PFs are inadequate or unavailable. We sought to compare oncologic and surgical outcomes between MVFFs and PFs in reconstructions of full-thickness chest wall defects.

METHODS

We retrospectively identified all patients who underwent chest wall resection at our institution from 2000 to 2022. Patients were stratified by flap reconstruction. End points were defect size, rate of complete resection, rate of local recurrence, and postoperative outcomes. Multivariable analysis was performed to identify factors associated with complications at 30 days.

RESULTS

In total, 536 patients underwent chest wall resection, of whom 133 had flap reconstruction (MVFF, n = 28; PF, n = 105). The median (interquartile range) covered defect size was 172 cm2 (100-216 cm2) for patients receiving MVFF versus 109 cm2 (75-148 cm2) for patients receiving PF (P = .004). The rate of R0 resection was high in both groups (MVFF, 93% [n = 26]; PF, 86% [n = 90]; P = .5). The rate of local recurrence was 4% in MVFF patients (n = 1) versus 12% in PF patients (n = 13, P = .3). Postoperative complications were not statistically different between groups (odds ratio for PF, 1.37; 95% confidence interval, 0.39-5.14]; P = .6). Operative time >400 minutes was associated with 30-day complications (odds ratio, 3.22; 95% confidence interval, 1.10-9.93; P = .033).

CONCLUSIONS

Patients with MVFFs had larger defects, a high rate of complete resection, and a low rate of local recurrence. MVFFs are a valid option for chest wall reconstructions.

En bloc resection of the recurrent pleural mesothelioma and reconstruction of the chest wall after immunotherapy: A case report

Malignant pleural mesothelioma (MPM) is associated with previous asbestos exposure, while more clinical insights into this disease have come from other case studies. Maximal cytoreduction is critical in disease control and might help to improve the prognosis. Here, a 41-year-old female presented with a 6-month history of a mass detected in the chest wall following resection of a right pleural mesothelioma 2 years previously. A fluorodeoxyglucose positron emission tomography/computed tomography scan showed a right chest wall mass with a blurred boundary 8.9 cm × 3.7 cm in size. The patient had received one cycle of bevacizumab, carboplatin, and pemetrexed, and two cycles of nivolumab, ipilimumab, and gemcitabine 5 months before admission. We subsequently resected the tumor, the involved diaphragm, and the fifth and sixth ribs, and titanium mesh and continuous suture were used to close the thoracic cage. The fixed paraffin-embedded tissues showed epithelioid pleural mesothelioma. The patient received nivolumab and ipilimumab postoperatively, and no recurrence was detected 16 months after surgery. En bloc resection with reconstructive surgery effectively removed the locally advanced malignancy and restored the biological function of the thorax with a favorable prognosis. Neoadjuvant immunotherapy might therefore be conducive to radical resection and perioperative immunotherapy might improve the prognosis.

The oncologic efficacy of extended thoracic resections

Locally invasive lung cancers pose unique challenges for management. Surgical resection of these tumors can pose high morbidity due to the invasion into surrounding structures, including the spine, chest wall, and great vessels. With advances in immunotherapy and chemoradiation, the role for radical resection of these malignancies and associated oncologic outcomes is evolving. This article reviews the current literature of extended thoracic resections with a focus on technical approach, functional outcomes, and oncologic efficacy.

Primary intrathoracic synovial cell sarcoma requiring radical resection of the chest wall and diaphragm with reconstruction using titanium mesh

Intrathoracic synovial cell sarcomas are extremely rare tumors with a high rate of recurrence after resection. We report one such case of synovial cell sarcoma arising from the chest wall, which was completely intrathoracic without an external component. The tumor was resected twice and in spite of adjuvant chemo-radiation the tumor recurred. Radical resection of the tumor with reconstruction of the chest wall and diaphragm using titanium mesh and polypropylene mesh respectively was done. A latissimus dorsi flap cover was provided. Titanium mesh is an excellent prosthesis of choice for reconstruction, as it provides stability and better cosmesis of the chest wall. Radical resection can be offered for suitable candidates, with very low morbidity and mortality.

The sternum reconstruction: Present and future perspectives

Sternectomy is a procedure mainly used for removing tumor masses infiltrating the sternum or treating infections. Moreover, the removal of the sternum involves the additional challenge of performing a functional reconstruction. Fortunately, various approaches have been proposed for improving the operation and outcome of reconstruction, including allograft transplantation, using novel materials, and developing innovative surgical approaches, which promise to enhance the quality of life for the patient. This review will highlight the surgical approaches to sternum reconstruction and the new perspectives in the current literature.

Chest-Wall Tumors and Surgical Techniques: State-of-the-Art and Our Institutional Experience

The chest wall can be involved in both primary and secondary tumors, and even today, their management and treatment continue to be a challenge for surgeons. Primary chest-wall tumors are relatively rare and include a large group of neoplasms that can arise from not only bone or cartilage of the chest wall but also from associated subcutaneous tissue from muscle and blood vessels. Secondary tumors refer to a direct invasion of the chest wall by neoplasms located elsewhere in the body, mainly metastases from breast cancer and lung cancer. En-bloc surgical excision of the lesion should ensure adequate negative margins to avoid local recurrence, and a full thickness surgical resection is often required, and it can result in important chest-wall defects such as skeletal instability or impaired breathing dynamics. The reconstruction of large defects of the chest wall can be complex and often requires the use of prosthetic and biologic mesh materials. This article aims to review the literature on these tumor entities, focusing on the main surgical techniques and the most recent advances in chest-wall resection and reconstruction. We also report on the institutional experience our center.

Intrathoracic scapular dislocation following radical surgical chondrosarcoma resection from chest wall

Locked scapula or intrathoracic scapular dislocation is an extremely rare entity encountered in the emergency department, with very few cases reported in literature. Conservative vs surgical approach in treating intrathoracic scapular dislocation is not well defined in literature. In this case report, we present a rare case of intrathoracic scapular dislocation, following multiple ribs resection due to malignant bone tumour, which was treated by closed manipulation reduction technique.

Surgical resection of chest wall sarcomas: an analysis of survival and predictors of outcome at an Australian multidisciplinary sarcoma service

BACKGROUND

Chest wall sarcomas are a rare group of tumours. Surgical resection is considered the mainstay of curative treatment, however, resection and reconstruction of chest wall defects presents complex issues for the clinician.

METHODS

A retrospective analysis of 59 patients undergoing surgical management of chest wall sarcoma between December 1996 and July 2020 was conducted across a multidisciplinary sarcoma service in Melbourne, Australia. Patient demographics, pathologic data, and long-term outcomes were recorded.

RESULTS

Mean age at surgery was 48.4 years (SD 18.3), and 66.1% were male. Median follow-up was 29 months (IQR 11.8, 51.0 months). Fifty-one patients presented with primary tumours, while the others had secondary tumours resected. Most tumours arose in bone (72.9%) as opposed to soft tissues (27.1%). Chondrosarcoma was the most common histologic subtype (50.8%). The most common reconstructive techniques involved the use of mesh (79.7%) or mesh supplemented with bone cement (33.9%). Overall survival at 1 and 5 years was 92% and 70%, respectively. Seven patients died of metastatic sarcoma during the follow up period with a median survival time of 27 months. Twelve patients had evidence of disease recurrence during the follow-up period. Stage 4 disease, soft tissue tumours, secondary tumours, leiomyosarcoma and UPS subtypes, and plating reconstruction were associated with increased disease recurrence.

CONCLUSIONS

The results suggest that outcomes for chest wall sarcoma are similar to extremity sarcomas and may be treated in a similar manner. Patients requiring adjuvant radiotherapy and those who develop disease-recurrence are more likely to have worse overall survival outcome despite complete surgical resection.

Porous Ceramic Sternal Prosthesis Implantation in a 13-Year-Old Patient Presenting with Metastatic Ewing's Sarcoma

Ewing's sarcoma is the second most frequent primary malignant bone tumor in adolescents and young adults. Locations on the thoracic wall represent up to 20% of primary and secondary locations. We present the case of a 13-year-old patient treated with the use of a radiolucency porous bioceramic prosthesis as a sternal replacement for a wide tumor resection in an oncologic context. Focal radiation therapy was not possible due to the high risk of severe myocardial injuries caused by the sternal location of the tumor. The sternum CERAMIL® (I.CERAM, Limoges, France), in porous alumina (Al ₂ O ₃ ) has already been implanted into adults in sternal replacement during its invasion by a tumor or its infectious destruction. There were no complication concerning the surgery. The last follow-up at 2 years postoperatively reveals a satisfactory clinical situation with any functional thoracic complaint and nor any functional respiratory symptoms. The porous alumina sternal prosthesis offers a reliable alternative for sternal replacement indications for children in an oncologic context.

Structural Failure of the BioBridge Rib Prosthesis After Chest Wall Resection

Chest wall reconstruction presents a challenging surgical problem with no universally recognized gold standard for the procedure. Various prosthetic and bioprosthetic materials exist for use in chest wall reconstruction, with bioprosthetic materials offering significant advantages in the case of a preoperatively infected surgical field. Here we present a case of the absorbable BioBridge system (Acute Innovations, Hillsboro, OR) used for chest well reconstruction and describe a novel complication of structural failure of the BioBridge plate, involving fracturing of the prosthesis with wound erosion, ultimately requiring reoperation and removal of the device.

[Reconstruction of post-resection chest wall defects in surgical treatment of invasive non-small cell lung cancer]

OBJECTIVE

To present the results of reconstruction of post-resection chest wall defects with nickel-titanium (TiNi) implants in patients with invasive NSCLC and to analyze the features of perioperative management.

MATERIAL AND METHODS

We enrolled 9 patients with NSCLC involving the ribs after lobectomy or pneumonectomy with chest wall reconstruction. Defects were closed used TiNi mesh and rib prostheses. We selected the shape and dimensions of artificial ribs individually before surgery according to CT data and 3D models of reinforcing elements.

RESULTS

There were male smokers aged 64.6±4.6 years among patients (range 58-73). T3N0M0 was diagnosed in 6 patients, T3N1M0 - 2, T3N2M0 - 1. Squamous cell carcinoma was verified in 4 (44.4%) patients, adenocarcinoma - in 5 (55.6%) patients. All patients had comorbidities. Mean Charlson's comorbidity index was 6.56±4.6. Dimension of chest wall defect varied from 78 to 100 cm². Postoperative period was uneventful without signs of respiratory failure. There were no lethal outcomes. Complications occurred in 33.3% of patients (prolonged air discharge through the drains, pleuritis and atrial fibrillation).

CONCLUSION

Surgical treatment of NSCLC spreading to the chest wall is a complex task requiring further improvement. Bioadaptive TiNi implants are a promising reinforcing material that allows successful reconstruction of post-resection chest wall defects with good anatomical, functional and cosmetic results. «Sandwich» technology is advisable for extensive defects. This approach includes 2 layers of knitted mesh and rib prostheses between these layers.

Evaluation of Clinical Performance of TiNi-Based Implants Used in Chest Wall Repair after Resection for Malignant Tumors

In this study, we assessed the outcomes after surgical treatment of thoracic post-excision defects in 15 patients, using TiNi knitted surgical meshes and customized artificial TiNi-based ribs. Methods: Eight patients were diagnosed with advanced non-small cell lung cancer (NSCLC) invading the chest wall, of which five patients were T₃N₀M₀, two were T₃N₁M₀, and one was T₃N₂M₀. Squamous cell carcinoma was identified in three of these patients and adenocarcinoma in five. In two cases, chest wall resection and repair were performed for metastases of kidney cancer after radical nephrectomy. Three-dimensional CT reconstruction and X-ray scans were used to plan the surgery and customize the reinforcing TiNi-based implants. All patients received TiNi-based devices and were prospectively followed for a few years. Results: So far, there have been no lethal outcomes, and all implanted devices were consistent in follow-up examinations. Immediate complications were noted in three cases (ejection of air through the pleural drains, paroxysm of atrial fibrillation, and pleuritis), which were conservatively managed. In the long term, no complications, aftereffects, or instability of the thoracic cage were observed. Conclusion: TiNi-based devices used for extensive thoracic lesion repair in this context are promising and reliable biomaterials that demonstrate good functional, clinical, and cosmetic outcomes.

Staged Chest Wall Reconstruction for Radiation-induced Costochondritis

Costochondritis after breast reconstruction and radiation therapy is rarely reported. Moreover, it is difficult to diagnose using computed tomography and magnetic resonance imaging; as such, wound debridement and reconstruction must be performed in several stages. A 51-year-old woman was diagnosed with invasive cancer of the right breast, and she underwent nipple sparing mastectomy and direct-to-implant breast reconstruction in November 2007. Thirteen years later, in September 2020, she experienced pain and swelling on her right breast. Incisional drainage and implant removal were performed in another clinic; however, the infection was not controlled. An implant-induced infection was suspected, and debridement was performed to a level where fresh tissue appeared in the upper layer of the intercostal muscle. Antibiotics and open dressing were used for 10 days; however, yellowish debris was noted, and third to fifth ribs and costal cartilages turned dark brown. Radiation-induced costochondritis was diagnosed based on clinical findings from the intraoperative field, wound course, and cartilage biopsy. Radical chest wall resection and reconstruction was performed using Teflon (Dupont/Chemours, Wilmington, Del.) and latissimus dorsi musculocutaneous flap. The patient was discharged 2 weeks after surgery without any complications. Costochondritis should be clinically diagnosed while performing the first debridement in staged operation. Radical chest wall resection is essential with chest wall reconstruction using Teflon and a latissimus dorsi musculocutaneous flap.

Pectoralis major myo-parenchymal flap for local reconstruction of partial mastectomy defects. Description of a new technique

INTRODUCTION

Breast conservation is the standard of care treatment for early breast cancer. Several oncoplastic approaches have been described for the reconstruction of partial breast defects. The multiplicity of techniques indicates that the ideal reconstructive technique is yet to be identified. There has been a recent emphasis on minimizing the magnitude of surgery. In this report, we describe our experience of using the pectoralis major muscle to fill relatively large post-tumorectomy breast defects.

PATIENTS AND TECHNIQUE

Nine patients were operated on for malignant breast lesions. Tumorectomy resection with surgical margin rendered a 40-50% breast defect. The parenchymal defect was repaired with an advancement muscle flap of the ipsilateral pectoralis major muscle.

RESULTS

All patients experienced a non-eventful postoperative course. The early cosmetic outcome was excellent in four patients, good in another four, and fair in one patient.

CONCLUSION

The pectoralis major flap is useful for local repair of upper half partial breast defects in non-ptosed, cup A-B breasts.

Innovative chest wall reconstruction with a locking plate and cement spacer after radical resection of chondrosarcoma in the sternum: A case report

BACKGROUND

Chondrosarcoma, a cartilage matrix producing tumor, is the second most commonly observed primary bone tumor after osteosarcoma, accounting for 15% of all chest wall malignancies. We herein report the case of a patient with chondrosarcoma of the sternum and our management of the chest wall defects that presented following radical tumor resection.

CASE SUMMARY

A 31-year-old patient presented to our hospital with dull pain and a protruding mass overlying the chest for 3 mo. The presence of nocturnal pain and mass size progression was reported, as were overhead arm elevation-related limitations. Computed tomography showed a focal osteoblastic mass in the sternum with bony exostosis and adjacent soft tissue calcification. Positron emission tomography-computed tomography revealed hypermetabolic activity with a mass located over the upper sternum. Magnetic resonance imaging showed a focal ill-defined bony mass of the sternum with cortical destruction and periosteal reaction. Preoperative biopsy showed a consistent result with chondrosarcoma with immunohistochemical positivity for S100 and focal positivity for IDH-1. The grade II chondrosarcoma diagnosis was confirmed by postoperative pathology. The patient underwent radical tumor resection and chest wall reconstruction with a locking plate and cement spacer. The patient was discharged 1 wk after surgery without any complications. At the 1-year follow-up, there was no local recurrence on imaging. The functional scores, including Constant Score, Nottingham Clavicle Score, and Oxford Shoulder Score, showed the absence of pain in the performance of daily activities or substantial functional disabilities.

CONCLUSION

The diagnosis of chondrosarcoma must be considered when chest wall tumors are encountered. The surgical reconstructive materials, with a locking plate and cement spacer, used in our study are cost-effective and readily-available for the sternum defect.

Interdisciplinary Radical "En-Bloc" Resection of Ewing Sarcoma of the Chest Wall and Simultaneous Chest Wall Repair Achieves Excellent Long-Term Survival in Children and Adolescents

Introduction: Ewing sarcomas of the chest wall, historically known as "Askin tumors" represent highly aggressive pediatric malignancies with a reported 5-year survival ranging only between 40 and 60% in most studies. Multimodal oncological treatment according to specific Ewing sarcoma protocols and radical "en-bloc" resection with simultaneous chest wall repair are key factors for long-term survival. However, the surgical complexity depends on tumor location and volume and potential infiltrations into lung, pericardium, diaphragm, esophagus, spine and major vessels. Thus, the question arises, which surgical specialties should join their comprehensive skills when approaching a child with Ewing sarcoma of the chest wall. Patients and Methods: All pediatric patients with Ewing sarcomas of the chest wall treated between 1990 and 2020 were analyzed focusing on complete resection, chest wall reconstruction, surgical complications according to Clavien-Dindo (CD) and survival. Patients received neo-adjuvant chemotherapy according to the respective Ewing sarcoma protocols. Depending on tumor location and organ infiltration, a multi-disciplinary surgical team was orchestrated to perform radical en-bloc resection and simultaneous chest wall repair. Results: Thirteen consecutive patients (seven boys and six girls) were included. Median age at presentation was 10.9 years (range 2.2-21 years). Neo-adjuvant chemotherapy (n = 13) and irradiation (n = 3) achieved significant reduction of the median tumor volume (305.6 vs. 44 ml, p < 0.05). En-bloc resection and simultaneous chest wall reconstruction was achieved without major complications despite multi-organ involvement. Postoperatively, one patient with infiltration of the costovertebral joint and laminectomy required surgical re-intervention (CD IIIb). 11/13 patients were treated with clear resections margins (R1 resection in one patient with infiltration of the costovertebral joint and marginal resection <1 mm in one child with multiple pulmonary metastases). All patients underwent postoperative chemotherapy; irradiation was performed in four children. Two deaths occurred 18 months and 7.5 years after diagnosis, respectively. Median follow-up for the remaining patients was 8.8 years (range: 0.9-30.7 years). The 5-year survival rate was 89% and the overall survival 85%. Conclusion: EWING specific oncological treatment and multi-disciplinary surgery performing radical en-bloc resections and simultaneous chest wall repair contribute to an improved survival of children with Ewing sarcoma of the chest wall.

Use of pedicled latissimus dorsi flap in anterior chest wall reconstruction

Successful surgical management of chest wall tumours relies on extensive chest wall resection with adequate margins. In large complex tumours, return to form and function is determined by appropriate skeletal and soft tissue reconstruction of the chest wall defect. We report an original case of a large 11×16×3 cm ulcerative basosquamous carcinoma of the anterior chest wall. Soft tissue reconstruction was performed with a unilateral pedicled latissimus dorsi flap. A multidisciplinary approach between thoracic and plastic surgeons was used in the planning, intraoperative and follow-up periods. This case highlights a good long-term functional and cosmetic outcome in complex chest wall reconstruction as a result of successful cross-specialty collaboration.

Combined Free Fibula Osteocutaneous and Anterolateral Thigh-Vastus Lateralis Free Flaps for Clavicule and Extensive Chest Wall Reconstruction After Sarcoma Resection

Combined extensive chest and neck reconstructions is a challenging procedure. The rapid development in microvascular surgery has allowed the cancer surgeons to successfully resect and reconstruct advanced malignancies in the neck and thoracic region. Herein we present a young female diagnosed with malignant mesenchymal sarcoma of the right side of the neck extending to right upper lung and anterior mediastinum. The patient was successfully treated with two microvascular free flaps in a multidisciplinary approach. Wide local resection of the tumor was done along with removal of right upper pulmonary lobe and the subclavian vessels. Vascular reconstruction was done with polytetrafluoroethylene grafts. A free fibula osteocutaneous flap was used for stabilization and reconstruction of the clavicle. Anterolateral thigh flap with vastus lateralis muscle was used for soft tissue reconstruction. All flaps survived and the patient had a good recovery at three months of follow-up. Future reports suggesting guidelines or algorithms for complex chest wall reconstruction should benefit of similar scenarios to the one reported here.

Epithelioid hemangioendothelioma of the sternum

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor composed of dendritic and endothelial cells, and accounts for less than 1% of all vascular tumors. The tumor may arise from any location in the body, but it has a predilection for veins of the extremities, the liver, bone, and skin. Herein, we report a case of a 43‐year‐old man who presented with a chest mass accompanied by chest pain. Computed tomography (CT) scan of the chest showed a 3 cm × 2 cm sternal mass in the chest wall. We performed tumor resection and reconstruction of the chest wall. EHE was confirmed via postoperative pathology. The patient underwent postoperative adjuvant radiotherapy, and no evidence of tumor recurrence was discovered during the one‐year follow up.

Reconstruction of Oncologic Sternectomy Defects: Lessons Learned from 60 Cases at a Single Institution

Oncologic sternectomy results in complex defects where preoperative planning is paramount to achieve best reconstructive outcomes. Although pectoralis major muscle flap (PMF) is the workhorse for sternal soft tissue coverage, additional flaps can be required. Our purpose is to evaluate defects in which other flaps beside PMF were required to achieve optimal reconstruction.

Anterior chest wall resection and sternal body wedge for primary chest wall tumour: reconstruction technique with biological meshes and titanium plates

Chest wall tumours are heterogeneous neoplasms, either primary or metastatic, with a malignancy rate of 50%. Surgical resection is one of the mainstays of the treatment, however, chest wall resections can be particularly challenging depending onto the resection size, site and patient habitus. The surgical strategy should be carefully analysed preoperatively, keeping in mind the need of an oncological radical resection (R0) in accordance to the reconstruction principles elicited by le Roux and Sherma since 1983, which include restoring the chest wall rigidity, preserving pulmonary mechanics, protect the intrathoracic organs, avoiding paradox movements of the chest cavity and, possibly, to reduce the thoracic deformity. In this context, we herewith report our surgical reconstruction technique following an anterior chest wall resection and sternal body wedge for a primary chest wall tumour (chondrosarcoma).

Complex chest wall wound managed by a novel technique of thoracoplasty

Thoracoplasty is a procedure to collapse the chest wall over a residual space in the thoracic cavity in order to abolish and avoid the complications associated with this dead space. Although effective in achieving this, the procedure is crippled by poor cosmetic appearance and functional outcome. We report a case of recalcitrant complex chest wall defect with a large cavity, marred by visible heart and poor availability of local muscles, that was successfully managed by a novel technique of thoracoplasty with acceptable postoperative appearance and function.

Keystone Perforator Island Flap for Postmastectomy Defect Resurfacing in Late-stage Breast Cancer Patients

Late-stage breast cancer usually presents with locally advanced disease, with or without metastasis. The primary tumor is typically large with skin infiltration which affects quality of life. Surgical resection will result in an extensive defect which potentially deteriorates patients’ quality of life if not properly managed. Keystone perforator island flap (KPIF) is a local advancement flap based on multiple perforators which can be a reliable reconstructive method to close an extensive defect.

Sternal Reconstruction With Non-Rigid Biologic Mesh Overlay

Adequate reconstruction of sternal defects is critical for function and quality of life. Reconstructive techniques have historically included a rigid component, most often a synthetic prosthesis, but these are associated with complications related to presence of a foreign body and the loss of native bone's flexibility and growth capability. Recently, biologic mesh has been used as an alternative for reconstructions of the chest wall, but not the sternum. We present the case of a large sternal defect after chondrosarcoma resection reconstructed with porcine acellular dermal matrix and soft tissue flaps, without rigid component, and with excellent patient outcome through 2 years of follow-up.

Sternal reconstruction with bone cement block using the rigid plate fixation technique

Chest computed tomography demonstrated a suspected primary tumor in the upper sternal body of a 48‐year‐old woman who presented with sternal pain. After being diagnosed with chondrosarcoma, she underwent sternal resection. Subsequent chest wall reconstruction was performed after careful planning using a bone cement block made of polypropylene mesh and polymethylmethacrylate. The block was fixed to the manubrium and ribs using the SternaLock System. She was discharged following an uneventful postoperative recovery, and is currently undergoing follow‐up.

Standardized Musculocutaneous Flap for the Coverage of Deep Sternal Wounds After Cardiac Surgery

BACKGROUND

Deep sternal wound infection remains a serious complication after cardiac surgery, leading to increased morbidity, mortality, and cost. The goal of our study was to develop a standardized, reproducible method to safely cover deep sternal wounds and ensure improved healing rates.

METHODS

The study was developed as a retrospective cohort study. We included 58 patients who received standardized latissimus dorsi flap coverage of a sternum defect wound after poststernotomy mediastinitis at our institution between September 2015 and June 2017.

RESULTS

The average age of the cohort was 66.75 years, and 51.72% of patients were men. The mean hospital stay was 26.83 days. Eight patients (14.75%) died during the hospital stay due to sepsis or heart failure. The average flap size was 137.13 cm². The mean operative time was 155 minutes. Seventy-four percent of patients developed a seroma at the donor site, which was treated conservatively with compression garments and taps, and 7% of patients developed a wound dehiscence of the donor site, which was treated conservatively with dressings. The mean follow-up time was 15 weeks. All 50 surviving patients showed complete wound healing on follow-up.

CONCLUSIONS

The latissimus dorsi pedicled flap is a safe, reproducible technique for coverage of deep sternal wounds, with few relevant perioperative complications. By setting definite parameters for the flap dissection and by ensuring a reliable blood supply, our method enables the coverage of these complex wounds by an interdisciplinary team in any cardiovascular surgical setting.

Reconstruction of anterior chest wall: a clinical analysis

Objective

To investigate the methods and clinical efficacy of reconstruction of chest defects with titanium sternal fixation system after the surgical resection of sternal tumors.

Methods

A total of 6 patients with sternal tumor who were diagnosed and underwent resection and repair of the chest wall defects by titanium plates system, from 2017.3 to 2017.11 in our hospital were reviewed. Their pathological types, surgical reconstruction methods, follow-up results were analyzed.

Results

Six cases of sternal tumor were completely resected and the sternums were reconstructed with titanium sternal fixation system. There was no operative death, postoperative chest wall deformity, abnormal breathing or complications of respiratory circulation. After 3 to 10 months of follow-up, there was no loose screw or plate exposure. Not only the thoracic appearances were good, but patients’ satisfaction was high.

Conclusions

Surgical resection is the best treatment for sternal tumors, no matter it is benign or malignant. Titanium sternal fixation system combine with other soft materials can reconstruct the chest wall well after resection, and this technique is efficient as well as easy to learn.

The painless combination of anatomically contoured titanium plates and porcine dermal collagen patch for chest wall reconstruction

Background

A plethora of new biomaterials and dedicated rib fixator implant systems have been introduced into the field of chest wall reconstruction. The aim of our study is to evaluate the surgical outcomes of a novel combination of the anatomically contoured titanium rib implant and porcine dermal collagen patch for chest wall reconstruction.

Methods

We performed a retrospective review of eight consecutive patients who underwent chest wall resection and reconstruction between January 2014 to August 2015 in a single institution. MatrixRib Fixation System and Permacol Surgical Implant were utilized to achieve chest wall reconstruction.

Results

The indication for reconstruction was malignant infiltration in 50% of patients. Three other subjects (37.5%) had chest wall resections to achieve adequate and safe surgical exposure. One patient had a right lung apical mycetoma with chest wall invasion. All patients underwent lung resections with the removal of 2 to 6 (median 3) ribs. Reconstruction was performed using the MatrixRib system, with a median of 2.5 (range, 2-4) ribs fixed in each patient. There was no post-operative mortality. One patient had a superficial wound infection which resolved with one week of oral antibiotics. Upon discharge, the pain scores were near zero with minimal analgesic requirements. None of the patients required repeat surgery or removal of their implants.

Conclusions

Our early experience indicates that the combination of the MatrixRib system and Permacol patch for chest wall reconstruction is safe and feasible with promising results in terms of anatomical restoration of the chest wall mechanics, infection and pain.

Chest wall reconstruction after tumor resection

Pediatric chest wall tumors are rare. Malignancies predominate of which sarcomas are the most common. Their resection and the subsequent reconstruction of the chest wall has been a surgical challenge since Dr. Frederick W. Parham published his first comprehensive account on the subject in 1898. Chest wall reconstruction is age, site and pathology dependent, must preserve long term function and cosmesis, must accommodate future growth and development, and must not be a hindrance to adjuvant radiotherapy. Bony reconstruction can be relatively simple or complex involving combinations of synthetic meshes, bioprosthetic materials, steel or titanium constructs, autografts, homografts and porcine or bovine xenografts. Soft tissue coverage can be achieved with direct closure, skin grafts, local advancement flaps, pedicled or free myocutaneous or osseomyocutaneous flaps or a combination of these. Complications to be avoided include scoliosis, pain and activity restriction, restrictive pulmonary deficits and interference with adjuvant radiotherapy which may result in tumor recurrence. Advances in cancer therapy have improved short- and long-term survival but significant functional and cosmetic challenges remain particularly for large chest wall defects in the very young. The future may lie with absorbable semi-rigid meshes, biointegratable acellular homografts and xenografts, demineralized bone matrices and bone marrow stromal cells, the patient's own lab-grown stem-cell based vascularized osseomyocutaneous chest wall grafts or the obsolescence of surgical resection altogether in the age of targeted anti-tumor and immune based therapy.

Materials and techniques in chest wall reconstruction: a review

Extensive chest wall resection and reconstruction are a challenging procedure that requires a multidisciplinary approach, including input from thoracic surgeon, plastic surgeon and oncologist. In particular chest wall neoplastic pathology is associated with high surgical morbidity and can result in full thickness defects hard to reconstruct. The goals of a successful chest wall reconstruction are to restore the chest wall rigidity, preserve pulmonary mechanic and protect the intrathoracic organs minimizing the thoracic deformity. In case of large full thickness defects synthetic, biologic or composite meshes can be used, with or without titanium plate to restore thoracic cage rigidity as like as more recently the use of allograft to reconstruct the sternum. After skeletal stability is established full tissue coverage can be achieved using direct suture, skin graft or local advancement flaps, pedicled myocutaneous flaps or free flaps. The aim of this article is to illustrate the indications, various materials and techniques for chest wall reconstruction with the goal to obtain the best chest wall rigidity and soft tissue coverage.
