Due to the increased prevalence of obesity in the last decades, bariatric surgery has been on the rise in recent years. Bariatric surgery is a compelling option for weight loss in obese patients with severe obesity-related comorbidities or for whom lifestyle modifications have proven ineffective. Redundant skin following significant weight loss is a common occurrence affecting up to 96% of patients who undergo bariatric surgery, negatively impacting physical and psychosocial health and detracting from activities of daily living. Statistics of the American Society of Plastic Surgeons show that 46,577 body contouring procedures were performed after massive weight loss in the USA in a 2020 report. Abdominoplasty, a well-established cosmetic surgery procedure for improving body contour, is performed by removing excess skin and fat from the abdominal wall and thereby restoring musculofascial integrity and skin elasticity, resulting in a more ideal body shape and increasing quality of life. Although abdominoplasty is a safe procedure, it has been associated with a higher complication rate compared with other body-contouring procedures. Technologic advances over the past decade have been developed as non-invasive alternatives or adjunctive tools to surgery to enhance cosmetic results and minimize complications. New energy-based technologies may supplant invasive surgery for mild to moderate skin laxity and/or diminish the extent of surgery and resulting scars. Plastic surgeons play a significant role in improving the quality of life of patients who suffer from obesity and underwent bariatric surgery. We are deeply convinced, however, that the advancement of knowledge and research in this field will determine the introduction of new technologies and custom-made techniques. This advancement will reduce the complication rate with a rapid reintegration of the patient into the world of work and resumption of daily activities.
Merkel cell carcinoma (MCC) is a rare, highly aggressive cutaneous neuroendocrine carcinoma. Controversy exists regarding optimal management of MCC as high-quality randomized studies and clinical trials are limited, and physicians are bound to interpret highly heterogeneous, retrospective literature in their clinical practice. Furthermore, the rising incidence and notably poor prognosis of MCC urges the establishment of best practices for optimal management of the primary tumor and its metastases. Herein, we summarized the relevant evidence and provided an algorithm for decision-making in MCC management based on the latest 2021 National Comprehensive Cancer Network guidelines. Additionally, we report current active MCC clinical trials in the United States. The initial management of MCC is dependent upon the pathology of the primary tumor and presence of metastatic disease. Patients with no clinical evidence of regional lymph node involvement generally require sentinel node biopsy (SLNB) while clinically node-positive patients should undergo fine needle aspiration (FNA) or core biopsy and full imaging workup. If SLNB or FNA/core biopsy are positive, a multidisciplinary team should be assembled to discuss if additional node dissection or adjuvant therapy is necessary. Wide local excision is optimal for primary tumor management and SLNB remains the preferred staging and predictive tool in MCC. The management of MCC has progressively improved in the last decade, particularly due to the establishment of immunotherapy as a new treatment option in advanced MCC. Ongoing trials and prospective studies are needed to further establish the best practices for MCC management.
Patients with early-stage disease typically have a good prognosis, but still have a risk of recurrence, even with negative sentinel lymph node biopsy (SLNB). This study explores the utility of routine imaging to detect metastases in patients with negative SLNB but high-risk 31 gene expression profile (31-GEP) scores. We retrospectively identified melanoma patients with negative SLNBs. Patients with high-risk GEP results were placed in the experimental group and patients without GEP testing were placed in the control group. Among both cohorts, recurrent melanoma groups were identified. The tumor burden at the time of recurrence and the time to recurrence were compared between experimental group patients with routine imaging and control group patients without imaging schedules. We identified 327 control patients and 307 experimental patients, of which 14.1% versus 20.5% had melanoma recurrence, respectively. Of the patients with recurrent melanoma, those in the experimental group were older (65.75 versus 59.20), had higher Breslow depths (3.72 mm versus 3.31 mm), and had advanced tumor staging (89.5% versus 71.4% of patients presenting clinical stage ≥ II) compared to the control group at primary diagnosis. However, melanoma recurrence was detected earlier (25.50 months versus 35.35 months) in the experimental group at a lower overall tumor burden (73.10 mm versus 27.60 mm). A higher percentage of experimental patients started immunotherapy when offered (76.3% and 67.9%). Patients who received routine imaging after high-risk GEP test scores had an earlier recurrence diagnosis with lower tumor burden, leading to better clinical outcomes.
Objective Robin Sequence (RS), characterized by micrognathia, glossoptosis, and upper airway obstruction, is an increasingly recognized diagnosis. An effective surgical intervention is mandibular distraction osteogenesis (MDO). This study analyzes published evidence regarding facial nerve dysfunction (FND) associated with MDO. Design and Setting According to PRISMA guidelines, a systematic review was carried out with databases queried in June 2019 using MESH terms, or equivalent terms, as follows: “distraction osteogenesis” and “Robin Sequence”. A review of original Spanish and English articles, were included. Outcome measures included the prevalence of FND; the affected branches; the rate of permanent vs. transient FND; the use of an internal vs. external device; the daily distraction rate; and finally, the overall distraction length. Subsequently, a meta-analysis was conducted to collate results regarding the prevalence of FND and the factors associated with it. Results Of 239 unique studies identified, 19 studies with 729 patients met inclusion criteria; 52 patients developed FND after MDO. A random-effects meta-analysis yielded a pooled prevalence of FND of 6.40%, with moderately heterogeneous studies (I2 = 41%, τ2 = 0.006). Marginal mandibular nerve involvement was most commonly noted. Nine studies reported transient FND, six permanent, one both, and two unspecified. Internal distractors were used in 8 studies and external in 3 and both in 2. Distraction rate was 1.00 to 2.00 mm/day and total distraction length ranged from 13.00 to 22.3 mm. Sample size was the only parameter inversely associated with rate of FND (p = 0.04). Conclusion This analysis of FND associated with MDO for patients with RS demonstrates a lack of consistent documentation. MDO-associated FND does not appear to be uncommon, and permanent dysfunction can occur. This review underscores the importance of thorough documentation to elucidate the mechanism of FND.
Summary: Radiation therapy following oncologic resection can result in incisional breakdown, delay or cessation of wound healing, and exposure of structures. Impaired wound healing often mandates free tissue transfer for definitive closure and preservation of function. We present the case of a 16-year-old male patient who had a major incisional dehiscence following resection of a synovial sarcoma of the lower leg after postoperative irradiation. The progressive wound breakdown failed to respond to local wound care or negative pressure therapy and progressed to expose tendons of the distal leg. The patient was successfully treated with SkinTE, an autologous homologous skin graft and casting. Healing was slow but the wound filled with granulation tissue (which covered the tendon), epithelialized, and led to an excellent cosmetic and functional result. This highlights the potential of stem cell therapy and other forms of regenerative methods in healing of complicated wounds.
Several reconstructive methods have been reported to restore the continuity of the aerodigestive tract following resection of pharyngeal and hypopharyngeal cancers. However, high complication rates have been reported after voice prosthesis insertion. In this setting, the ileocolon free flap (ICFF) offers a tubularized flap for reconstruction of the hypopharynx while providing a natural phonation tube. Herein, we systematically reviewed the current evidence on the use of the ICFF for reconstruction of the aerodigestive tract. A systematic literature search was conducted across PubMed MEDLINE, Web of Science, ScienceDirect, Scopus, and Ovid MEDLINE(R). Data on the technical considerations and surgical and functional outcomes were extracted. Twenty-one studies were included. The mean age and follow-up were 54.65 years and 24.72 months, respectively. An isoperistaltic or antiperistaltic standard ICFF, patch flap, or chimeric seromuscular-ICFF can be used depending on the patients' needs. The seromuscular chimeric flap is useful to augment the closure of the distal anastomotic site. The maximum phonation time, frequency, and sound pressure level (dB) were higher with ileal segments of 7 to 15 cm. The incidence of postoperative leakage ranged from 0 to 13.3%, and the majority was occurring at the coloesophageal junction. The revision rate of the microanastomosis ranged from 0 to 16.6%. The ICFF provides a reliable and versatile alternative for reconstruction of middle-size defects of the aerodigestive tract. Its three-dimensional configuration and functional anatomy encourage early speech and deglutition without a prosthetic valve and minimal donor-site morbidity.
PURPOSE:With widespread use of sentinel lymph node biopsy (SLNB) in melanoma, the accuracy of this procedure has been examined, quantified, and improved. However, the reported sensitivity and specificity of the procedure have ranged from 64 to 100%, with false-negative rates (FNR) ranging from 5.6 to 21%. Herein, we review a single-surgeon's experience in a large patient cohort with the purpose of evaluating the accuracy of a combination technique in SLNB. METHOD:All melanoma patients who underwent SLNB surgery by the senior author at Cleveland Clinic in February 2011 to December 2021 were included. All patients underwent SLNB using a combination of gamma and ICG for SLN identification. RESULTS:1,000 patients with mean age of 61 met the inclusion criteria. 220 patients had a positive SLNB with a mean number of 1.25 positive nodes of from an average of 2.86 nodes removed. From the 277 positive nodes, 247 (90%) were identified using combination of gamma and ICG (n=180/220), 21 (7%) using Gamma only (n= 26/ 220) and 8 (2%) using ICG only (n=14/220). 470 had a negative SLNB with an average of 2.9 nodes removed and a FNR of 2.3%. Mean follow-up was 2.3 years. CONCLUSION:We report one of the lowest false negative rates in a large patient cohort using a combination technique of gamma and ICG in SLNB, proving it a reliable technique in detecting melanoma nodal involvement.
