What are the short- and long-term abdominal consequences of an omentectomy? A systematic review.

This review provides an overview regarding the abdominal effects of an omentectomy, with or without extra-peritoneal reconstructions. In general, reported complication rates were low. Short-term complications involved ileus, bowel stenosis, abdominal abscess and sepsis (range 0.0%-23%). Donor-site hernia was mainly reported as long-term complication (up to 32%) and negligible gastrointestinal complications were observed. However, the level of evidence and methodological quality are quite low with a maximum of 8.5 years follow-up.

Prognostic tools for hypertrophic scar formation based on fundamental differences in systemic immunity.

Unpredictable hypertrophic scarring (HS) occurs after approximately 35% of all surgical procedures and causes significant physical and psychological complaints. Parallel to the need to understanding the mechanisms underlying HS formation, a prognostic tool is needed. The objective was to determine whether (systemic) immunological differences exist between patients who develop HS and those who develop normotrophic scars (NS) and to assess whether those differences can be used to identify patients prone to developing HS. A prospective cohort study with NS and HS groups in which (a) cytokine release by peripheral blood mononuclear cells (PBMC) and (b) the irritation threshold (IT) after an irritant (sodium lauryl sulphate) patch test was evaluated. Univariate regression analysis of PBMC cytokine secretion showed that low MCP-1, IL-8, IL-18 and IL-23 levels have a strong correlation with HS (P < .010-0.004; AUC = 0.790-0.883). Notably, combinations of two or three cytokines (TNF-a, MCP-1 and IL-23; AUC: 0.942, Nagelkerke R2 : 0.727) showed an improved AUC indicating a better correlation with HS than single cytokine analysis. These combination models produce good prognostic results over a broad probability range (sensitivity: 93.8%, specificity 86.7%, accuracy 90,25% between probability 0.3 and 0.7). Furthermore, the HS group had a lower IT than the NS group and an accuracy of 68%. In conclusion, very fundamental immunological differences exist between individuals who develop HS and those who do not, whereas the cytokine assay forms the basis of a predictive prognostic test for HS formation, the less invasive, easily performed irritant skin patch test is more accessible for daily practice.

Patient-reported Outcomes after ADM-assisted Implant-based Breast Reconstruction: A Cross-sectional Study.

BACKGROUND: Although the use of acellular dermal matrices (ADMs) in implant-based reconstruction increases, there is a lack of studies evaluating patient-reported outcome measures after this reconstruction method. We aim to evaluate the patient satisfaction after ADM-assisted implant-based breast reconstruction (IBBR) in 1 of the largest series of patients undergoing ADM-assisted IBBR. METHODS: Patients with ADM-assisted IBBR were invited to fill out the BREAST-Q, a validated and standardized questionnaire to measure patient satisfaction after a breast reconstruction. A retrospective chart review was performed to identify patient and surgical characteristics. RESULTS: In total, 208 patients (38.4%) responded and reported a mean satisfaction of 70.6 ± 20.2 with their breasts and 78.0 ± 20.5 with the outcome. An overall complication rate of 7.7% was noted, with 1.5% severe complications leading to hospital readmission (0.5%) and implant removal (0.5%). Patients with complications and unilateral reconstruction for oncological reasons reported overall less satisfaction rates compared with patients with bilateral, preventive surgery, and an uncomplicated postoperative course. Strongly related domains indicate the importance of patient satisfaction with their breasts and outcome on psychosocial and sexual functioning and satisfaction with information on satisfaction with breasts, outcome, and surgeon. CONCLUSION: There is an increased demand for patient-reported outcome measures in a changing practice to which the opinion of the patient assumes a larger role. With high satisfaction rates, ADM-assisted IBBR is a valuable reconstruction method, provided that complication rates remain low. Hence, it should only be performed in a selected group of women.

Intraoperative evaluation of perfusion in free flap surgery: A systematic review and meta-analysis.

BACKGROUND: Free flap survival relies on adequate tissue perfusion. We aim to give an overview of the available literature of all objective methods to intraoperatively assess free flap tissue perfusion, and the effects on (partial) flap loss. METHODS: A systematic review and meta-analysis according to the PRISMA guidelines was performed (PubMed, Cochrane Library, Embase) regarding English language articles. Meta-analyses were performed by pooling means and slopes using random-effect models. RESULTS: Sixty-four articles were included reporting on 2369 procedures in 2009 patients with various indications. Reported methods were fluorescence imaging (FI), laser Doppler, oxygen saturation, ultrasound, (dynamic) infrared thermography, venous pressure, and microdialysis. Intraoperative tissue perfusion was adequately measured by the use of FI and laser Doppler, leading to surgical intervention or altered flap design, and increased flap survival. Meta-analysis showed a mean time until onset of the dye to become visible of 18.4 (7.27; 29.46, Q P < 0.001) sec. The relative intensity of the flap compared to the intensity curve of normal tissue was 75.92% (65.85; 85.98, Q P = 0.719). The mean difference in the slope value of the oxygen tensions before and after the anastomosis was -0.09 (-0.12; -0;06 Q P = 0.982). No convincing evidence was found for the use of other methods. CONCLUSIONS: Based on the current literature, FI and laser Doppler are most suitable to intraoperatively measure free flap tissue perfusion, resulting in improved flap survival. However, this review was limited by the available literature. Additional studies are necessary to investigate the predictive value of intraoperative perfusion measurement.

Breast-specific factors determine cosmetic outcome and patient satisfaction after breast-conserving therapy: Results from the randomized COBALT study.

BACKGROUND AND OBJECTIVES: To identify breast-specific factors and the role of tumor, treatment, and patient-related items in influencing patient opinion on cosmesis and satisfaction after breast-conserving therapy (BCT). METHODS: Data from the randomized COBALT study was used. At 3, 12, and 36 months, 128 patients with T1-T2 breast cancer completed a questionnaire on breast-specific factors and overall cosmetic outcome and patient satisfaction, using a 4-point Likert scale. RESULTS: There was a strong positive correlation between breast-specific factors, overall cosmetic outcome,and satisfaction at all time-points. Excellent/good cosmetic outcomes and satisfaction decreased during follow-up. A shift was noted in the degree of influence of the various breast-specific factors. At 3 years, symmetry factors such as size, shape, and nipple position largely determined a patient's opinion on the final cosmesis, followed by firmness. The risk of an unacceptable outcome was associated with young age and large excision volumes. CONCLUSION: A questionnaire including breast-specific questions provides important information on final cosmetic results and satisfaction after BCT. These outcomes can also be of great value as quality indicators and pre-operative counseling. The major influence of breast-specific factors on asymmetry underlines the importance of achieving an optimal excision volume at the initial procedure.

Breast-conserving surgery following neoadjuvant therapy-a systematic review on surgical outcomes.

PURPOSE: Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer treatment. One of the main goals of NACT is to reduce the extent of local surgery of the breast and axilla. The aim of this study was to determine surgical outcomes for patients receiving breast-conserving therapy (BCT) after NACT, including margin status plus secondary surgeries, excision volumes, and cosmetic outcomes. METHODS: A systematic review was performed in accordance with PRISMA principles. Pubmed, MEDLINE, Embase, and the Cochrane Library were searched for studies investigating the results of BCT following NACT. The main study outcomes were margin status, additional local therapies, excision volumes, and cosmetic outcomes. Non-comparative studies on NACT were also included. Exclusion criteria were studies with less than 25 patients, and studies excluding secondary mastectomy patients. FINDINGS: Of the 1219 studies screened, 26 studies were deemed eligible for analysis, including data from 5379 patients treated with NACT and 10,110 patients treated without NACT. Included studies showed wide ranges of tumor-involved margins (2-39.8%), secondary surgeries (0-45.4%), and excision volumes (43.2-268 cm3) or specimen weight (26.4-233 g) after NACT. Most studies were retrospective, with a high heterogeneity and a high risk of bias. Cosmetic outcomes after NACT were reported in two single-center cohort studies. Both studies showed acceptable cosmetic outcomes. INTERPRETATION: There is currently insufficient evidence to suggest that NACT improves surgical outcomes of BCT. It is imperative that clinical trials include patient outcome measures in order to allow monitoring and meaningful comparison of treatment outcomes in breast cancer.

Breast-conserving therapy for breast cancer: Cosmetic results and options for delayed reconstruction.

OBJECTIVES: Optimisation of the cosmetic outcome after breast-conserving therapy (BCT) is important. We aimed to determine the cosmetic outcome following BCT and factors influencing this cosmesis and identify the most favourable options for delayed breast reconstruction. MATERIALS AND METHODS: Four reconstructive surgeons evaluated the cosmetic outcome of 109 patients after BCT. Additionally, the surgeons indicated which patients were amenable for delayed reconstruction and the preferred type of reconstruction. The inter- and intra-observer agreement of the surgeons was rated. RESULTS: The mean overall cosmetic outcome was rated as fair (2.7/4.0, SD 0.9, 1.0-4.0). Risk factors for a poor cosmesis were larger breast size (OR 3.81, p = 0.040), larger tumour (OR 1.63, p = 0.028) and axillary lymph node dissection (ALND) (OR 3.09, p = 0.013). Reconstruction of the ipsilateral side was recommended in 55.6% and 94.5% and contralateral reconstruction in 16.7% and 73.3% of patients with good and poor cosmesis, respectively. Flap reconstruction and lipofilling were most commonly reported for the ipsilateral, and breast reduction for the contralateral breast, with reasonable improvement expected (2.2/4.0, SD 0.5, 1.08-3.3). The inter- (0.5-0.7) and intra-observer (0.63-0.79) agreement of the cosmesis was moderate to good, however, poor regarding the recommended reconstruction techniques (mainly < 0.50). CONCLUSION: Cosmetic outcome after BCT is influenced by breast and tumour size and ALND. Although several reconstructive options are available, the optimal method for revision surgery has not yet been determined. Future studies are necessary to obtain evidence-based guidelines for reconstructive surgery after BCT.

Cosmetic outcome and quality of life are inextricably linked in breast-conserving therapy.

INTRODUCTION: Cosmetic results and quality of life (QoL) are increasingly important in the treatment of breast cancer. This study was designed to determine the relationship between QoL and both subjectively and objectively measured cosmetic outcomes of breast-conserving therapy (BCT), and its course over time. METHODS: A total of 128 breast cancer patients who underwent BCT as part of a prospective randomized controlled trial were included. QoL was measured using the EORTC QLQ-C30 and QLQ-BR23 at baseline, 3, 6, 12, and 36 months. Cosmetic outcome was determined by patient self-evaluation, panel evaluation, and BCCT.core software. RESULTS: By 36 months, all QoL factors except arm symptoms had returned to baseline or improved. After adjustment for patient and tumor characteristics, a significantly better QoL in terms of body image, pain, and arm and breast symptoms was found for good/excellent cosmetic outcomes compared to fair/poor outcomes, as measured by both patient self-evaluation and panel evaluation. The BCCT.core showed no correlation with any QoL factors. CONCLUSION: There is a high correlation between poor cosmetic outcome and low scores on quality of life indicators, underlining the importance of achieving a good cosmetic outcome after BCT.

Two-stage implant-based breast reconstruction compared with immediate one-stage implant-based breast reconstruction augmented with an acellular dermal matrix: an open-label, phase 4, multicentre, randomised, controlled trial.

BACKGROUND: The evidence justifying the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR) is limited. We did a prospective randomised trial to compare the safety of IBBR with an ADM immediately after mastectomy with that of two-stage IBBR. METHODS: We did an open-label, randomised, controlled trial in eight hospitals in the Netherlands. Eligible women were older than 18 years with breast carcinoma or a gene mutation linked with breast cancer who intended to undergo skin-sparing mastectomy and immediate IBBR. Randomisation was done electronically, stratified per centre and in blocks of ten to achieve roughly balanced groups. Women were assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. The primary endpoint was quality of life and safety was assessed by the occurrence of adverse outcomes. Analyses were done per protocol with logistic regression and generalised estimating equations. This study is registered at Nederlands Trial Register, number NTR5446. FINDINGS: 142 women were enrolled between April 14, 2013, and May 29, 2015, of whom 59 (91 breasts) in the one-stage IBBR with ADM group and 62 (92 breasts) in the two-stage IBBR group were included in analyses. One-stage IBBR with ADM was associated with significantly higher risk per breast of surgical complications (crude odds ratio 3·81, 95% CI 2·67-5·43, p<0·001), reoperation (3·38, 2·10-5·45, p<0·001), and removal of implant, ADM, or both (8·80, 8·24-9·40, p<0·001) than two-stage IBBR. Severe (grade 3) adverse events occurred in 26 (29%) of 91 breasts in the one-stage IBBR with ADM group and in five (5%) of 92 in the two-stage IBBR group. The frequency of mild to moderate adverse events was similar in the two groups. INTERPRETATION: Immediate one-stage IBBR with ADM was associated with adverse events and should be considered very carefully. Understanding of selection of patients, risk factors, and surgical and postsurgical procedures needs to be improved. FUNDING: Pink Ribbon, Nuts-Ohra, and LifeCell.

Lethal Necrotizing Cellulitis Caused by ESBL-Producing E. Coli after Laparoscopic Intestinal Vaginoplasty.

BACKGROUND: The absence of a functional vagina has a negative effect on the quality of life of women. Multiple surgical procedures have been described for vaginal reconstruction in these patients. CASE: We present a case of an 18-year-old transgender woman, who underwent laparoscopic intestinal vaginoplasty as vaginal reconstruction, and subsequently developed septic shock and multiple organ failure on the basis of an extended-spectrum ß-lactamase-producing Escherichia coli. A severe progression of the necrotizing fasciitis was lethal, despite repeated surgical debridement, intravenous antibiotic use, and supportive care at the intensive care unit. SUMMARY AND CONCLUSION: Although vaginal reconstruction has a positive influence on the quality of life in transgender women, physicians and patients need to be aware of serious complications that might arise.

Autologous Fat Grafting in Cosmetic Breast Augmentation: A Systematic Review on Radiological Safety, Complications, Volume Retention, and Patient/Surgeon Satisfaction.

BACKGROUND: Autologous fat grafting (AFG) is increasingly used in cosmetic surgery. However, its efficacy and safety are still ambiguous. Both a comprehensive overview and recapitulation of the relevant literature provide current evidence on the efficacy and outcomes of AFG in cosmetic breast surgery. OBJECTIVES: This review provides an up-to-date overview of the literature on AFG in cosmetic breast augmentation. METHODS: A systematic review of the literature on AFG used for cosmetic breast augmentation was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. This study included selected studies that were published between January 1996 and February 2016 and reported on 10 patients or more who had a minimal mean follow-up period of 1 year. RESULTS: In this study, 22 articles that reported on 3565 patients with follow-up periods ranging from 12 to 136 months were included. A complication rate of 17.2% (95% CI 15.9-18.5) was seen. Indurations were the most frequent complication (33.3%, 95% CI 20.4-46.3), followed by persistent pain (25%, 95% CI 0.5-49.5), and hematoma (16.4%, 95% CI 14.5-18.4). Mammograms revealed micro-calcifications (9.0%, 95% CI 6.4-11.5) and macro-calcifications (7.0%, 95% CI 3.8-10.2). The mean volume retention was 62.4% (range, 44.7-82.6%), with a satisfaction rate of 92% in patients and 89% in surgeons. CONCLUSIONS: AFG is a promising method in achieving autologous cosmetic breast augmentation with satisfactory volume retention and satisfaction rates in eight and six studies, respectively. Complications and radiological findings are comparable to those after implant augmentation. Future studies should focus on cancer occurrence and detection to further substantiate AFG safety. In addition, grafting methods and the use of auxiliary procedures to identify factors leading to better outcomes in terms of volume retention should be investigated. Finally, objective questionnaires are needed to represent patient satisfaction. LEVEL OF EVIDENCE: 3 Therapeutic.

The Use of Autologous Fat Grafting for Treatment of Scar Tissue and Scar-Related Conditions: A Systematic Review.

BACKGROUND: Scar tissue can cause cosmetic impairments, functional limitations, pain, and itch. It may also cause emotional, social, and behavioral problems, especially when it is located in exposed areas. To date, no gold standard exists for the treatment of scar tissue. Autologous fat grafting has been introduced as a promising treatment option for scar tissue-related symptoms. However, the scientific evidence for its effectiveness remains unclear. This systematic review aims to evaluate the available evidence regarding the effectiveness of autologous fat grafting for the treatment of scar tissue and scar-related conditions. METHODS: A systematic literature review was performed using MEDLINE, Cochrane Library, EMBASE, and Web of Science. No language restrictions were imposed. RESULTS: Twenty-six clinical articles were included, reporting on 905 patients in total. Meta-analysis was not performed because of the heterogeneous methodology demonstrated among the articles. Main outcome measures were scar appearance and skin characteristics, restoration of volume and/or (three-dimensional) contour, itch, and pain. All publications report a beneficial effect of autologous fat grafting on scar tissue. There is statistical significant improvement of the scar appearance, skin characteristics, and pain. Itch and restoration of volume and three-dimensional contour also improved. CONCLUSIONS: Autologous fat grafting is used to improve a variety of symptoms related to scar tissue. This systematic review suggests that autologous fat grafting provides beneficial effects with limited side effects. However, the level of evidence and methodological quality are quite low. Future randomized controlled trials with a methodologically strong design are necessary to confirm the effects of autologous fat grafting on scar tissue and scar-related conditions.
