Outcomes and Quality of Life After Resorbable Synthetic Ventral Hernia Repair in Contaminated Fields.

INTRODUCTION: The ideal mesh type for hernia repair in a contaminated field remains controversial. Data regarding outcomes beyond 1 year and the impact on quality of life (QoL) are unknown. This study aims to evaluate the long-term surgical outcomes and patient-reported outcomes (PROs) after contaminated repair with poly-4-hydroxybutyrate (P4HB) mesh. MATERIALS METHODS: Patients undergoing a contaminated hernia repair with P4HB between 2015 and 2020 were identified. Surgical site occurrences and hernia recurrences were recorded. Long-term PROs as defined by the Abdominal Hernia-Q and Hernia-Related Quality-of-Life Survey were assessed. RESULTS: Fifty-five patients were included with a mean age of 54.5 years, a body mass index of 34 kg/m2, and a defect size of 356.9 ± 227.7 cm2. Median follow-up time was 49 months with a reoperation rate of 14.5% and a hernia recurrence rate of 7.3%. Of the 55 patients, 37 completed preoperative and postoperative PRO questionnaires. When comparing preoperative with postoperative Abdominal Hernia-Q, there was significant improvement in overall PROs (2.1 vs 3.5, P < 0.001). This improvement was maintained with no significant changes between postoperative scores over the course of 5 years. Patients with complications saw the same improvement in postoperative PRO scores as those without complications. CONCLUSIONS: Our study found a low hernia recurrence and acceptable long-term reoperation rates in patients undergoing hernia repair with P4HB mesh in a contaminated setting. We demonstrate a sustained significant improvement in QoL scores after hernia repair. These data yield insight into the long-term outcomes and QoL improvement, providing physicians further knowledge to better counsel their patients.

Obesity as a Risk Factor in Cosmetic Abdominal Body Contouring: A Systematic Review and Meta-Analysis.

BACKGROUND: The incidence of obesity is on the rise around the globe. Outside of the massive weight loss (MWL) patient population, knowledge of risk factors associated with abdominal body contouring (BC) is limited. This systematic review and meta-analysis assesses the impact of obesity has on cosmetic abdominal BC outcomes. METHODS: A systematic review conducted in accordance with PRISMA 2020 was done. PubMed, Embase, Scopus, and COCHRANE databases were reviewed under search syntax "obesity," "abdominoplasty," "panniculectomy," and "body contouring" for articles. Cosmetic was defined as abdominoplasty or panniculectomy outside the context of MWL. Obesity was defined as BMI ≥ 30 kg/m2. Studies reporting postoperative outcomes with less than 50% of their population involving MWL patients were included. Postoperative outcomes were assessed by pooled analysis and meta-analysis. RESULTS: Of 3088 initial studies, 16 met inclusion criteria, and nine were used for pooled and meta-analysis. Meta-analysis demonstrated that obesity was associated with more seromas (OR 1.45, 1.06-1.98, p = 0.02), hematomas (OR 2.21, 1.07-4.57, p = 0.03), and total surgical site occurrences (OR 1.99, 1.30-3.04, p = 0.0016). There was no significant difference in odds of any other complications. Analysis by obesity class showed no significant increase in odds in seromas or wound dehiscence. CONCLUSIONS: This review demonstrates obesity increased odds of postoperative complications following cosmetic abdominal BC. However, risk of complications does not continue to increase with higher obesity class. A BMI ≥ 30 kg/m2 should not be a strict contraindication to cosmetic abdominal BC. Instead, plastic surgeons should evaluate patients on a case-by-case basis. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Preoperative Botulinum Toxin for Abdominal Wall Reconstruction in Massive Hernia Defects-A Propensity-Matched Analysis.

PURPOSE: Reconstruction of massive incisional hernias (IHs) poses a significant challenge with high rates of recurrence. Preoperative chemodenervation using botulinum toxin (BTX) injections in the abdominal wall is a technique that has been used to facilitate primary fascial closure. However, there is limited data directly comparing primary fascial closure rates and postoperative outcomes after hernia repair between patients who do and do not receive preoperative BTX injections. The objective of our study was to compare the outcomes of patients who did and did not receive BTX injections before abdominal wall reconstruction. METHODS: This is a retrospective cohort study including adult patients from 2019 to 2021 who underwent IH repair with and without preoperative BTX injections. Propensity score matching was performed based on body mass index, age, and intraoperative defect size. Demographic and clinical data were recorded and compared. The statistical significance level was set at P < 0.05. RESULTS: Twenty patients underwent IH repair with preoperative BTX injections. Twenty patients who underwent IH repair without preoperative BTX injections were selected to comprise a 1:1 propensity-matched control cohort. The average defect size was 663.9 cm2 in the BTX group and 640.7 cm2 in the non-BTX group (P = 0.816). There was no difference in average age (58.6 vs 59.2 years, P = 0.911) and body mass index (33.0 vs 33.2 kg/m2, P = 0.911). However, there was a greater proportion of male patients in the BTX group (85% vs 55%, P = 0.082).Primary fascial closure was achieved in 95% of BTX patients and 90% of non-BTX patients (P = 1.0). Significantly fewer patients in the BTX group required component separation techniques to achieve primary fascial closure (65% vs 95%, P = 0.044). There was no significant difference in any postoperative surgical and medical outcomes. Hernia recurrence was 10% in the BTX group and 20% in non-BTX group (P = 0.661). CONCLUSIONS: In our study, we observed a lower rate of component separations to achieve primary fascial closure among patients with massive hernia defects who received preoperative BTX injections. These results suggest that preoperative BTX injections may "downstage" the complexity of hernia repair with abdominal wall reconstruction in patients with massive hernia defects and reduce the need for component separation.

The Role of Dedicated Research Training in Promoting Academic Success in Plastic Surgery: Analysis of 949 Faculty Career Outcomes.

This study aimed to analyze the association between completion of research training and career success in American plastic surgery faculty to aid trainees in their decisions to perform research fellowships. Methods: A cross-sectional analysis of attending academic plastic surgeons in the United States was conducted. Outcomes were compared between faculty who completed research training (research fellowship, PhD, or MPH) and those who did not. Outcomes included promotion to full professor and/or department chair, h-index, and attainment of National Institutes of Health funding. Outcomes were analyzed using chi-squared tests, t tests, and multivariable regressions. Results: A total of 949 plastic surgery faculty members were included, and of those, 185 (19.5%) completed dedicated research training, including 13.7% (n = 130) who completed a research fellowship. Surgeons who completed dedicated research training were significantly more likely to achieve full professorship (31.4% versus 24.1%, P = 0.01), obtain National Institutes of Health funding (18.4% versus 6.5%, P < 0.001), and have a higher mean h-index (15.6 versus 11.6, P < 0.001). Dedicated research fellowships were independently predictive of achieving full professorship (OR = 2.12, P = 0.002), increased h-index (ß = 4.86, P < 0.001), and attainment of National Institutes of Health funding (OR = 5.06, P = 0.01). Completion of dedicated research training did not predict an increased likelihood of becoming department chair. Conclusion: The performance of dedicated research training was predictive of improved markers of career success in plastic surgery and should be considered beneficial in both the short and long term.

Advanced Endoscopic Rescue of a Complication (Duodenojejunostomy Leak) After a Pylorus-Preserving Pancreaticoduodenectomy in a Post-Esophagectomy Patient with Pancreatic Adenocarcinoma: A Case Report and Review of the Literature.

Background: Approximately 4% of patients develop a second upper gastrointestinal cancer after esophagectomy, and nearly 60,000 people are diagnosed with pancreatic cancer in the United States each year. The need for a Whipple procedure after esophagectomy is rarely reported. Post-esophagectomy anatomy, particularly the vascular supply, makes this a complex operation. Herein, we describe the advanced endoscopic rescue of a duodenojejunostomy (DJ) leak after pylorus-preserving pancreaticoduodenectomy (PPPD) in a post-esophagectomy patient. Presentation: A 72-year-old male with a remote history of esophageal cancer treated with minimally invasive three-hole esophagectomy and chemoradiation presented to our institution for evaluation and management of newly diagnosed pancreatic cancer. The patient had undergone common bile duct (CBD) stent placement by his gastroenterologist 2 weeks earlier after experiencing jaundice, weight loss, and steatorrhea. Endoscopic ultrasound confirmed the presence of a pancreatic head and neck mass, obstructing and dilating the main pancreatic duct and CBD. Fine-needle biopsy revealed a poorly differentiated adenocarcinoma. A PPPD was performed without intraoperative complications. The patient was subsequently readmitted with a DJ leak requiring interventional radiology and advanced endoscopic intervention. Conclusions: PPPD in patients with pancreatic cancer can be performed after previous esophagectomy. Careful dissection is crucial to avoid injury to the remaining right gastric and right gastroepiploic arteries that supply the gastric conduit after esophagectomy. The DJ is at risk after this operation, and access to tertiary care inclusive of interventional radiology and advanced endoscopic teams is critical to the correction and healing of a leak of this anastomosis.

Choroidal amelanotic tumours: clinical differentiation of benign from malignant lesions in 5586 cases.

PURPOSE: To investigate demographics and clinical features of patients with amelanotic choroidal tumours. DESIGN: Retrospective analysis. METHODS: Comparison of demographic and clinical features of various amelanotic choroidal tumours based on stratification by patient age, sex and tumour diameter. Included were all patients with amelanotic choroidal tumours evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, Pennsylvania, USA, over a 45-year time period. RESULTS: A total of 5586 amelanotic choroidal tumours in 4638 eyes of 4441 patients were included with a mean age at presentation of 58 years (median 60, range 0.1-100 years). Most patients were white (95%), female (56%) and with unilateral lesion (96%). By comparison, amelanotic melanoma presented at a younger mean age (57 years) compared with metastasis (60 years, p<0.001), nevus (61 years, p<0.001), lymphoma (65 years, p<0.001), sclerochoroidal calcification (70 years, p<0.001) and peripheral exudative haemorrhagic chorioretinopathy (80 years, p<0.001). Melanoma presented at an older mean age compared with osteoma (30 years, p<0.001), granuloma (42 years, p<0.001), haemangioma (49 years, p<0.001) and inflammatory choroidal lesions (49 years, p<0.001). Differences in race and sex were also seen between the various amelanotic choroidal lesions. With few exceptions, amelanotic melanoma had significantly larger basal diameter, greater thickness, more frequent association with subretinal fluid and more often ultrasonographically hollow, compared with other amelanotic choroidal lesions. CONCLUSION: Understanding the demographic and clinical features of amelanotic choroidal melanoma and other amelanotic lesions could lead to an earlier and more accurate diagnosis.

Uveal metastasis in 1111 patients: Interval to metastasis and overall survival based on timing of primary cancer diagnosis.

PURPOSE: To evaluate interval between primary cancer diagnosis and uveal metastasis and assess survival outcomes based on whether the primary cancer was diagnosed before or after uveal metastasis. METHODS: In this retrospective analysis, all patients with uveal metastasis evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, PA, USA between February 1, 1974 and June 1, 2017 were included. Features and outcomes based on timing of primary cancer diagnosis, whether before or after diagnosis of uveal metastasis, were assessed. RESULTS: A total of 2214 uveal metastases were diagnosed in 1310 eyes of 1111 consecutive patients. Primary cancer was known prior to uveal metastasis in 742 patients (67%) and not known in 369 (33%). Of those not known, the primary cancer was later found in 192 patients (17%) and never found in 177 patients (16%). For those with known primary cancer, mean interval from primary cancer diagnosis to uveal metastasis was 5.2 years with differences in primary sites of gastrointestinal (2.1 years, p = 0.003), lung (2.2 years, p < 0.001), breast (6.5 years, p < 0.001), and thyroid (13 years, p < 0.001). By Kaplan-Meier analysis, the 5-year overall survival showed no difference between patients with primary cancer found before (28%) vs after (20%) vs never found (33%), relative to uveal metastasis. CONCLUSION: Of 1111 patients with uveal metastasis, early-onset uveal metastases were found with lung and gastrointestinal tract cancers, whereas late-onset metastases were found with breast and thyroid cancers. Overall survival did not vary on whether the primary tumor was diagnosed before, after, or never found, relative to uveal metastasis.

Suprachoroidal Hemorrhage Simulating Melanoma in Idiopathic Thrombocytopenic Purpura.

BACKGROUND: We report a case of suprachoroidal hemorrhage simulating choroidal melanoma in a patient with idiopathic thrombocytopenic purpura (ITP). METHODS: Case report. RESULTS: A 79-year-old white male with a history of lung adenocarcinoma, ITP, and mild anemia noted blurred vision with photopsia and floaters in the right eye (OD) that worsened over 2 months. He was found to have a pigmented choroidal mass and was referred for evaluation of possible choroidal melanoma. Visual acuity was 20/30 in the affected right eye and 20/25 in the left eye (OS). There was mild vitreous hemorrhage and 2 pigmented peripheral choroidal tumors in the temporal and nasal fundus OD. B-scan ultrasonography confirmed 2 acoustically hollow tumors, and transillumination demonstrated no shadowing. Optical coherence tomography over the lesions revealed choroidal elevation with suprachoroidal scalloped surface. Fluorescein and indocyanine green angiography revealed normal choroidal fluorescence and cyanescence with no "double circulation" of melanoma and no dye blockage, suggesting a suprachoroidal location. These findings were suggestive of suprachoroidal hemorrhage rather than melanoma. The patient was managed conservatively, and the hemorrhages demonstrated spontaneous resolution. CONCLUSION: Ocular manifestations of ITP are uncommon. Rarely, spontaneous suprachoroidal hemorrhage simulating melanoma can occur. A thorough clinical evaluation with multimodal imaging is critical to establishing the appropriate diagnosis.
