RESUMO

BACKGROUND: Pleural neoplasms are rare and can be subdivided into pleural metastasis and primary pleural neoplasms. Non-mesothelioma primary pleural neoplasms are a diverse group of extremely rare pathologies. CASE PRESENTATION: In this case series, we describe the presentation and management of two rare primary pleural neoplasms. A first case describes a primary pleural yolk sac tumor treated with neoadjuvant chemotherapy, extended pleurectomy decortication, and hyperthermic intrathoracic chemotherapy. In a second case we describe the management of a primary pleural synovial sarcoma by neoadjuvant chemotherapy and extrapleural pneumonectomy. A complete resection was obtained in both cases and the post-operative course was uncomplicated. No signs of tumor recurrence were noted during follow-up in the first patient. In the second patient a local recurrence was diagnosed 6 months after surgery. CONCLUSION: Neo-adjuvant chemotherapy followed by extensive thoracic surgery, including hyperthermic intrathoracic chemotherapy, is a feasible treatment strategy for non-mesothelioma primary pleural neoplasms, but careful follow-up is required.

RESUMO

The Department of Ophthalmology, Sahlgrenska University Hospital, has until recently been the only eye clinic in the Nordic countries to perform Mohs' micrographic surgery of basal cell carcinoma. This has led to the practice of only the most complicated basal cell carcinomas being operated on with this technique. The purpose of this study was to present the results of these surgeries in patients with at least 5 years of follow-up. A retrospective study of all patients operated upon in 2010-2015 was performed. Data were gathered from their medical charts. Primary outcome was recurrence of basal cell carcinoma. One-hundred and sixty-seven patients were operated on. Mohs' micrographic surgery was used for tumours that were judged as highly aggressive on preoperative biopsy, had ill-defined borders, had recurred after previous surgery, or a combination of these factors. Nine recurrences (5.4% of all radical Mohs' micrographic surgeries) were diagnosed after a mean postoperative time of 37 months (4-84 months). Interestingly, all of these 9 recurrences after Mohs' micrographic surgery were in patients who had such surgery because of a recurrent basal cell carcinoma to start with. Good results can be achieved when operating on the most complicated periocular basal cell carcinomas with Mohs' micrographic surgery but special care has to be taken to ensure radical borders when operating on recurring basal cell carcinomas.

RESUMO

BACKGROUND: Atrial arrhythmias (AA) commonly affect patients with cardiac amyloidosis (CA) and are a contributing risk factor for the development of heart failure (HF). This study sought to investigate the long-term efficacy and impact of catheter ablation on HF progression in patients with CA and AA. METHODS: Thirty-one patients with CA and AA undergoing catheter ablation were retrospectively included (transthyretin-ATTR CA 61% and light chain-AL CA 39%). AA subtypes included atrial fibrillation (AFib) in 22 (paroxysmal in 10 and persistent in 12), atrial flutter (AFl) in 17 and atrial tachycardia (AT) in 11 patients. Long-term AA recurrence rates were evaluated along with the impact of sinus rhythm (SR) maintenance on HF and mortality. RESULTS: AA recurrence was observed in 14 patients (45%) at a median of 3.5 months (AFib n = 8, AT n = 6, AFl = 0). Post-cardioversion, medical therapy or catheter ablation, 10 patients (32%) remained in permanent AA. Over a median follow-up of 19 months, all-cause mortality was 39% (n = 12): 3 with end-stage HF, 5 due to late complications of CA, 1 sudden cardiac death, 1 stroke, 1 COVID 19 (and one unknown). With maintenance of SR following catheter ablation, significant reductions in serum creatinine and natriuretic peptide levels were observed with improvements in NYHA class. Two patients required hospitalization for HF in the SR maintenance cohort compared to 5 patients in the AA recurrence cohort (p = 0.1). All 3 patients with deaths secondary to HF had AA recurrence compared to 11 out of the 28 patients whom were long-term survivors or deaths not related to HF (p = 0.04). All-cause mortality was not associated with AA recurrence. CONCLUSION: This study demonstrates moderate long-term efficacy of SR maintenance with catheter ablation for AA in patients with CA. Improvements in clinical and biological status with positive trends in HF mortality are observed if SR can be maintained.

RESUMO

BACKGROUND: Perioperative blood transfusion (PBT) has been associated with worse prognosis in several malignancies. For renal cell carcinoma (RCC), the effect of PBT is still debated. OBJECTIVE: To evaluate the impact of PBT on prognosis after nephrectomy in patients with RCC. METHODS: This study is A systematic review and meta-analysis of published article data (PRISMA protocol) for literature related to PBT and RCC through extensive search of EMBASE, Medline via PubMed, Web of Science and Cochrane Library, language limited to English, with no time constraint until May 20, 2022. We pooled the results of multivariable cox regression analyses from each study, with subgroup analyses by dose and timing of transfusion. All analyses were done using Stata14. RESULTS: A total of 12 studies involving 27,683 participants were included. Our meta-analysis pooled the results of multivariable cox regression analysis in each study, showing that PBT is associated with higher overall Mortality (OM; hazard ratio [HR] = 1.34, 1.23-1.44), cancer-specific mortality (CSM; HR = 1.35, 1.20-1.51), and disease recurrence (HR = 1.54, 1.18-1.89). when only patients with nonmetastatic RCC were included, PBT was still associated with higher OM (HR = 1.29, 1.11-1.47) and disease recurrence (HR = 1.58, 1.18-1.98), but the association with CSM (HR = 1.26, 0.99-1.52) was not statistically significant. In subgroup analysis by transfusion dose, small (1-2) units of PBT were not associated with CSM (HR = 1.84, 0.95-2.73), but large (≥3) units were associated with higher CSM (HR = 2.98, 1.74-4.22) and disease recurrence (HR = 1.99, 1.31-2.67). Each additional unit of PBT resulted in a higher CSM (HR = 1.07, 1.04-1.10). In subgroup analysis by transfusion timing, intraoperative transfusion was associated with higher CSM and disease recurrence, but postoperative transfusion was not. CONCLUSIONS: PBT is associated with higher OM, CSM and disease recurrence. This adverse effect seems to be particularly significant in high-dose intraoperative transfusion. It is necessary to limit the overuse of PBT, especially high-dose intraoperative transfusion, in order to improve the prognosis of patients undergoing nephrectomy for RCC.

RESUMO

INTRODUCTION: Disparities in postmastectomy reconstructive care are widely acknowledged. However, there is limited understanding regarding the impact of reconstructive services on cancer recurrence and breast cancer-related mortality. Therefore, this study aims to examine how patient-specific factors and breast reconstruction status influence recurrence-free survival and mortality rates in breast cancer patients. METHODS: Retrospective chart review was performed to collect data on patients who underwent mastectomy at 2 institutions within the New York-Presbyterian system from 1979 to 2019. Sociodemographic information, medical history, and the treatment approach were recorded. Propensity score matching, logistic regression, unpaired t test, and chi-square test were used for statistical analysis. RESULTS: Overall, cancer recurrence occurred in 6.62% (317) of patients, with 16.8% (803) overall mortality rate. For patients who had relapsed disease, completion of the reconstruction sequence was correlated with an earlier detection of cancer recurrence and improved survival odds (P < 0.05). Stratified analysis of the reconstruction group alone showed mortality benefit among patients who underwent free flap procedures (P < 0.05). CONCLUSION: Patients undergoing breast reconstruction after mastectomy are likely to have better access to follow-up care and improved interfacing with the healthcare system. This may increase the speed at which cancer recurrence is detected. This study highlights the need for consistent plastic surgery referral and continued monitoring by all members of the breast cancer care team for cancer recurrence among patients.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is the 3rd most common malignancy with the liver being the most common site of metastases. The recurrence rate of colorectal liver metastases (CRLM) after liver resection (LR) is notably high, with an estimated 40% of patients experiencing recurrence within 6 months. In this context, we conducted a meta-analysis to synthesize and evaluate the reliability of evidence pertaining to prognostic factors associated with early recurrence (ER) in CRLM following LR. METHODS: Systematic searches were conducted from the inception of databases to July 14, 2023, to identify studies reporting prognostic factors associated with ER. The Quality in Prognostic Factor Studies (QUIPS) tool was employed to assess risk-of-bias for included studies. Meta-analysis was then performed on these prognostic factors, summarized by forest plots. The grading of evidence was based on sample size, heterogeneity, and Egger's P value. RESULTS: The study included 24 investigations, comprising 12705 individuals, during an accrual period that extended from 2007 to 2023. In the evaluation of risk-of-bias, 22 studies were rated as low/moderate risk, while two studies were excluded because of high risk. Most of the studies used a postoperative interval of 6 months to define ER, with 30.2% (95% confidence interval [CI], 24.1-36.4%) of the patients experiencing ER following LR. 21 studies were pooled for meta-analysis. High-quality evidence showed that poor differentiation of CRC, larger and bilobar-distributed liver metastases, major hepatectomy, positive surgical margins, and postoperative complications were associated with an elevated risk of ER. Additionally, moderate-quality evidence suggested that elevated levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA199), lymph node metastases (LNM) of CRC, and a higher number of liver metastases were risk factors for ER. CONCLUSION: This review has the potential to enhance the efficacy of surveillance strategies, refine prognostic assessments, and guide judicious treatment decisions for CRLM patients with high risk of ER. Additionally, it is essential to undertake well-designed prospective investigations to examine additional prognostic factors and develop salvage therapeutic approaches for ER of CRLM.

RESUMO

OBJECTIVES: This study was conducted to develop nomograms for predicting repeat intrahepatic recurrence (rIHR) and overall survival (OS), after radiofrequency ablation (RFA), treatment in patients with recurrent colorectal liver metastases (CLMs) after hepatectomy based on clinicopathologic features. METHODS: A total of 160 consecutive patients with recurrent CLMs after hepatectomy who were treated with ultrasound-guided percutaneous RFA from 2012 to 2022 were retrospectively included. Patients were randomly divided into a training cohort and a validation cohort, with a ratio of 8:2. Potential prognostic factors associated with rIHR and OS, after RFA, were identified by using the competing-risks and Cox proportional hazard models, respectively, and were used to construct the nomogram. The nomogram was evaluated by Harrell's C-index and a calibration curve. RESULTS: The 1-, 2-, and 3-year rIHR rates after RFA were 58.8%, 70.2%, and 74.2%, respectively. The 1-, 3- and 5-year OS rates were 96.3%, 60.4%, and 38.5%, respectively. In the multivariate analysis, mutant RAS, interval from hepatectomy to intrahepatic recurrence ≤ 12 months, CEA level >5 ng/ml, and ablation margin <5 mm were the independent predictive factors for rIHR. Mutant RAS, largest CLM at hepatectomy >3 cm, CEA level >5 ng/ml, and extrahepatic disease were independent predictors of poor OS. Two nomograms for rIHR and OS were constructed using the respective significant variables. In both cohorts, the nomogram demonstrated good discrimination and calibration. CONCLUSIONS: The established nomograms can predict individual risk of rIHR and OS after RFA for recurrent CLMs and contribute to improving individualized management.

RESUMO

BACKGROUND: Histopathological and molecular features have been proposed to hold prognostic information, but few have been validated. The aim of this retrospective study was to validate the Genetic And Morphological Evaluation ('GAME') score and assess the impact of histological characteristics on the prognosis in patients with colorectal liver metastases. METHODS: Data were collected from 176 patients with metastatic colorectal cancer undergoing liver resection at Hospital de la Santa Creu i Sant Pau. Patients were classified into Genetic And Morphological Evaluation score groups and relapse-free survival and overall survival were calculated. Histopathological changes in colorectal liver metastases were documented and prognostic variables were selected to create a post-surgery score, called the Histopathological, Clinical, And Molecular ('HICAM') score. RESULTS: Regarding the Genetic And Morphological Evaluation score, the high-risk group had a median relapse-free survival of 8.8 months, compared with 20.5 months for the low-risk group (P = 0.005), and the high-risk group had a median overall survival of 37.8 months, compared with 67.0 months for the low-risk group (P = 0.005). Histological examination of 144 liver samples showed that the desertic immune phenotype was associated with worse overall survival in the multivariable analysis (P = 0.020). The Histopathological, Clinical, And Molecular score variables were age at diagnosis, tumour burden score, carcinoembryonic antigen levels greater than or equal to 20 ng/ml, primary tumour resection, TNM stage at diagnosis, molecular status, histopathological growth patterns, and immune phenotypes of the liver. The high-risk group had a median relapse-free survival of 8.4 months, compared with 20.4 months for the low-risk group (P < 0.001), and a median overall survival of 30.4 months, compared with 105.0 months for the low-risk group (P < 0.001). CONCLUSION: The Genetic And Morphological Evaluation score was validated as a preoperative prognostic tool to predict candidacy for liver resection. The Histopathological, Clinical, And Molecular score could be useful to assess adjuvant treatment after hepatic resection.

RESUMO

PURPOSE: The role of repeat resection for recurrent glioblastoma (rGB) remains equivocal. This study aims to assess the overall survival and complications rates of single or repeat resection for rGB. METHODS: A single-centre retrospective review of all patients with IDH-wildtype glioblastoma managed surgically, between January 2014 and January 2022, was carried out. Patient survival and factors influencing prognosis were analysed, using Kaplan-Meier and Cox regression methods. RESULTS: Four hundred thirty-two patients were included, of whom 329 underwent single resection, 83 had two resections and 20 patients underwent three resections. Median OS (mOS) in the cohort who underwent a single operation was 13.7 months (95% CI: 12.7-14.7 months). The mOS was observed to be extended in patients who underwent second or third-time resection, at 22.9 months and 44.7 months respectively (p < 0.001). On second operation achieving > 95% resection or residual tumour volume of < 2.25 cc was significantly associated with prolonged survival. There was no significant difference in overall complication rates between primary versus second (p = 0.973) or third-time resections (p = 0.312). The use of diffusion tensor imaging (DTI) guided resection was associated with reduced post-operative neurological deficit (RR 0.37, p = 0.002), as was use of intraoperative ultrasound (iUSS) (RR 0.45, p = 0.04). CONCLUSIONS: This study demonstrates potential prolongation of survival for rGB patients undergoing repeat resection, without significant increase in complication rates with repeat resections. Achieving a more complete repeat resection improved survival. Moreover, the use of intraoperative imaging adjuncts can maximise tumour resection, whilst minimising the risk of neurological deficit.

RESUMO

We compared the clinical outcomes of second breast conserving therapy (2ndBCT) versus salvage mastectomy (sMT) for the treatment of ipsilateral breast tumour recurrences (IBTR). 195 patients who presented with an IBTR after previous breast conserving treatment were salvaged either with re-excision and perioperative interstitial brachytherapy (n=39) or sMT (n=156). A total dose of 5×4.4Gy was delivered to the tumour bed, on 3 consecutive days. The median follow-up time was 59 and 56 months. During follow-up 4 (10.2%) and 28 (17.9%) second local recurrences occurred after 2ndBCT and sMT, respectively. There were no significant differences between treatments in 5-year oncological outcomes (local and regional recurrence-free survival, disease- and metastasis-free survival, cancer-specific and overall survival). After 2ndBCT, the rate of good to excellent cosmesis was 70%. 2ndBCT is a safe and feasible option for the management of IBTR, resulting similar 5-year oncological outcomes and better cosmetic results compared to sMT.

RESUMO

A young woman in her 20s was found to have a left breast malignant phyllodes tumour by ultrasound-guided core needle biopsy, after identifying a palpable lump. She then underwent lumpectomy excision with >1 cm gross margins; however, final pathology demonstrated <1 cm margins at the superior margin. She then underwent re-excision of superior and medial margins to ensure at least a 1 cm margin. Biopsy tract was not excised at initial or re-excision surgery. Approximately 6 weeks after completion lumpectomy, the patient noted a new palpable mass near the previous biopsy site and underwent punch biopsy. Final pathology of this new mass was concordant with early recurrence. The patient then underwent lumpectomy of the new mass along with excision of the overlying skin and biopsy tract with >1 cm margins.

RESUMO

A woman in her 30s, non-smoker, presented at the emergency department two times because of spontaneous pneumothorax. The first episode was treated with small bore catheter drainage, while during the second episode-occurring only 1 week later-thoracoscopic talcage was attempted. The postoperative course was characterised by slow clinical and radiological resolution, and recurrence 3 days after discharge. Eventually, multiportal video-assisted thoracoscopic exploration identified an interfissural solid mass. Resection and further work-up revealed the diagnosis of 'low-risk' solitary fibrous tumour (SFT) stage pT1N0M0. The interdisciplinary tumour board advised no adjuvant therapy. A CT thorax was scheduled in 1 year for follow-up. The patient was discharged without complications and has had no recurrences of pneumothorax at 6 months of follow-up. This report shows that SFT can easily be missed on initial presentation and should be considered in the differential diagnosis of pneumothorax, especially when frequently recurring.

RESUMO

OBJECTIVES: To compare oncologic outcomes after segmentectomy with division of segmental bronchus, artery and vein (complete anatomic segmentectomy) versus segmentectomy with division of <3 segmental structures (incomplete anatomic segmentectomy). METHODS: We conducted a single-centre, retrospective analysis of patients undergoing segmentectomy from March 2005 to May 2020. Operative reports were audited to classify procedures as complete or incomplete anatomic segmentectomy. Patients who underwent neoadjuvant therapy or pulmonary resection beyond indicated segments were excluded. Survival was estimated with Kaplan-Meier models and compared using log-rank tests. Cox proportional hazards models were used to estimate hazard ratios (HRs) for death. Cumulative incidence functions for loco-regional recurrence were compared with Gray's test, with death considered a competing event. Cox and Fine-Gray models were used to estimate cause-specific and subdistribution HRs, respectively, for loco-regional recurrence. RESULTS: Of 390 cases, 266 (68.2%) were complete and 124 were incomplete anatomic segmentectomy. Demographics, pulmonary function, tumour size, stage and perioperative outcomes did not significantly differ between groups. Surgical margins were negative in all but 1 case. Complete anatomic segmentectomy was associated with improved lymph node dissection (5 vs 2 median nodes sampled; P < 0.001). Multivariable analysis revealed reduced incidence of loco-regional recurrence (cause-specific HR = 0.42; 95% confidence interval 0.22-0.80; subdistribution HR = 0.43; 95% confidence interval 0.23-0.81), and non-significant improvement in overall survival (HR = 0.66; 95% confidence interval: 0.43-1.00) after complete versus incomplete anatomic segmentectomy. CONCLUSIONS: This single-centre experience suggests complete anatomic segmentectomy provides superior loco-regional control and may improve survival relative to incomplete anatomic segmentectomy. We recommend surgeons perform complete anatomic segmentectomy and lymph node dissection whenever possible.

RESUMO

No randomized trials exist to inform the peripheral surgical margins or depth of wide excision for eyelid melanoma. We performed a meta-analysis examining surgical margins and Breslow depth for eyelid melanomas. A systematic review was performed in August 2022 using PubMed, Cochrane, and Medline databases (1/1/1990 to 8/1/2022). Inclusion criteria included studies reporting surgical treatment of primary cutaneous melanomas of the eyelid with reported surgical margins. Ten articles were included. The studies were examined by surgical margin size (group 1: ≤ 0.5 cm; group 2 > 0.5 cm and ≤ 1.5 cm) and Breslow depth (group 1: ≤ 1 mm; group 2: > 1 mm). The odds ratio (OR) for local recurrence was 2.55 [95% CI 0.36-18.12], p = 0.18; regional metastasis was 0.70 [95% CI 0.00-23671.71], p = 0.48; and distant metastasis was 2.47 [95% CI 0.00-1687.43], p = 0.66. When examining by Breslow depth, the OR for local recurrence was 0.53 [95% CI 0.14-1.94], p = 0.34; regional metastasis was 0.14 [0.00-176.12], p = 0.54; and the OR for distant metastasis was 0.24 [95% CI 0.01-8.73], p = 0.46. There was a trend toward higher likelihood of recurrence and metastasis in the ≤ 0.5 cm group. Similarly, there is a trend toward higher likelihood of recurrence and metastasis with Breslow depth > 1 mm. A surgical margin of at least 0.5 cm and achievement of negative margins via permanent sections or MMS are likely needed to prevent adverse outcomes. En face sectioning may be a superior method of histological processing for eyelid melanoma.

RESUMO

OBJECTIVE: To assess the role of neoadjuvant chemotherapy (NAC) before robot-assisted radical cystectomy (RARC) for patients with variant histology (VH) muscle-invasive bladder cancer (MIBC). METHODS: Retrospective review of 988 patients who underwent RARC (2004-2023) for MIBC. Primary outcomes included the utilization of NAC among this cohort of patients, frequency of downstaging, and discordance between preoperative and final pathology in terms of the presence of VH. Secondary outcomes included disease-specific (DSS), recurrence-free (RFS), and overall survival (OS). RESULTS: A total of 349 (35%) had VH on transurethral resection or at RARC. The 4 most common VH subgroups were squamous (n = 94), adenocarcinoma (n = 64), micropapillary (n = 34), and sarcomatoid (n = 21). There was no difference in OS (log-rank: P = 0.43 for adenocarcinoma, P = 0.12 for micropapillary, P = 0.55 for sarcomatoid, P = 0.29 for squamous), RFS (log-rank: P = 0.25 for adenocarcinoma, P = 0.35 for micropapillary, P = 0.83 for sarcomatoid, P = 0.79 for squamous), or DSS (log-rank P = 0.91 for adenocarcinoma, P = 0.15 for micropapillary, 0.28 for sarcomatoid, P = 0.92 for squamous) among any of the VH based on receipt of NAC. Patients with squamous histology who received NAC were more likely to be downstaged on final pathology compared to those who did not (P < 0.01). CONCLUSION: Our data showed no significant difference in OS, RFS, or DSS for patients with VH MIBC cancer who received NAC before RARC. Patients with the squamous variant who received NAC had more pathologic downstaging compared to those who did not. The role of NAC among patients with VH is yet to be defined. Results were limited by small number in each individual group and lack of exact proportion of VH.

RESUMO

INRODUCTION: Mucinous cystic neoplasms are rare tumors. They may originate from either ovaries, pancreas, or other intra-abdominal sites, but rarely from the mesentery. CASE HISTORY: A 22-year-old nulliparaous woman, who had undergone laparascopic bilateral cystectomy for recurrent ovarian mass, presented with pain in abdomen, backache, and menstrual irregularities. Provisionally diagnosed as ovarian carcinoma, she underwent bilateral salpingo-oophorectomy and sigmoid colectomy. However, the histopathological examination revealed mucinous cystic neoplasm of the mesentery. DISCUSSION: Thus, complete resection of the cysts with meticulous gross and histopathological examination remains the gold standard to differentiate mucinous cystic neoplasm (MCN) of the mesentery from its mimics, especially malignant counterparts, enabling clinicians to adequately manage such patients. Here, we present a case of recurrent MCN of mesentery (mesocolon), mimicking as ovarian carcinoma confirmed on histopathological examination, in a young adult.

RESUMO

BACKGROUND: Biosynthetic meshes afford the cost advantages of being made from fully synthetic material, but are also biodegradable, making them a versatile option that can be used in both clean and contaminated cases. The aim of this study is to evaluate the safety profile and long-term outcomes of using GORE BIO-A (BIO-A) as an adjunct to abdominal wall reconstruction in all wound classes. METHODS: A retrospective review identified patients undergoing abdominal hernia repair using BIO-A from October 2008 to June 2018. The primary outcome was hernia recurrence rate. Only patients with at least 6-month follow-up were included when looking at recurrence rates. Secondary outcomes included 30-day morbidity categorized according to CDC Surgical Site Infection Criteria, return to operating/procedure room (RTOR), 30-day readmission, length of stay (LOS), and mortality. RESULTS: A total of 207 patients were identified, CDC Wound Classification breakdown was 127 (61.4%), 41 (19.8%), 14 (6.8%), and 25 (12.1%) for wound classes I, II, III, and IV, respectively. Median follow-up was 55.4 months (range 0.2-162.4). Overall recurrence rate was 17.4%. Contaminated cases experienced higher recurrence rates (28.8% versus 10.4%, p = 0.002) at a mean follow up of 46.9 and 60.8 months for contaminated and clean patients, respectively. Recurrent patients had higher BMI (32.4 versus 28.4 kg/m2, p = 0.0011), larger hernias (162.2 versus 106.7 cm2, p = 0.10), higher LOS (11.1 versus 5.6 days, p = 0.0051), and higher RTOR rates (16.7% versus 5.6%, p = 0.053). 51 (24.5%) patients experienced some morbidity, including 19 (9.2%) surgical site occurences, 7 (3.4%) superficial surgical site infections, 16 (7.7%) deep surgical site infections, and 1 (0.5%) organ space infection. CONCLUSION: This study affirms the use of biosynthetic mesh as a cost-effective alternative in all wound classifications, yielding good outcomes, limited long-term complications, and low recurrence. rates.
