Robotic Spleen Preserving Distal Pancreatectomy (Warshaw Techniqe) In A 12-Year-Old Female., Rachel Harvey, Begum Akay, Pavan Brahmamdam

Conference Presentation Abstracts

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare entity seen in young females. Complete surgical resection is often curative. This video shows a robotic spleen preserving distal pancreatectomy for a SPN in a 12-year-old female using the Warshaw technique. This technique preserves the short gastric and left gastroepiploic vessels allowing for splenic survival after ligation of the splenic vessels. This video demonstrates the feasibility of using the robot to perform this procedure in a pediatric patient. MRI at 18 months follow up showed that the spleen was completely perfused, with no evidence of recurrence or metastasis.

Laparoscopic Assisted Robotic Radical Prostatectomy With Pelvic Lymph Node Dissection Using Viable Cryopreserved Umbilical Tissue To Improve Cavernosal Nerve Function., Joshua Volin, Brett Watson, Lior Kopel, Samantha Kraemer, Jason Hafron

Conference Presentation Abstracts

Radical prostatectomy is the preferred treatment for patients with clinically localized prostate cancer and is typically performed using a robotic approach. Surgical techniques that preserve the neurovascular bundle minimize the risk of incontinence and erectile dysfunction post-operatively. Umbilical cord tissue is a relatively new technique, which has been shown to reduce inflammation and promote regenerative healing. In this video we show a robotic radical prostatectomy with bilateral nerve sparing technique utilizing a cryopreserved umbilical cord allograft nerve wrap.

Individuals who are immunocompromised (IC) due to disease or therapy are at increased risk of herpes zoster (HZ), with HZ cases in IC populations also resulting in increased health care resource use and costs as compared with the immunocompetent population. This study assesses the cost-effectiveness of recombinant zoster vaccine (RZV) versus no vaccine for the prevention of HZ in IC adults aged ≥ 18 years in the United States (US). Methods. A Markov model with a one-year cycle length was developed to follow a hypothetical cohort of one million IC individuals for a 30-year time horizon. The model estimates …

Recurrent Focal Segmental Glomeruloscleosis Progressing To Collapsing Glomerulopathy In Renal Graft Of An Autopsy Study, C Thorburn, K J Jabbar, W Li, H Kanaan, P Zhang

Conference Presentation Abstracts

Introduction/Objective: Collapsing glomerulopathy (CGN) mainly occurs in patients of African descent because a majority of these patients have APOL-1 gene mutations that results in damage of terminally differentiated podocytes, diffuse fusion of foot processes, and podocyte hyperplasia. Idiopathic FSGS is associated with high rates of recurrent FSGS in renal transplants and can be seen in patients with APOL-1 gene mutations as well, but recurrent FSGS progressing to CGN is not reported. Here we report an autopsy case with renal transplant showing recurrent FSGS progressing to CGN. Methods/Case Report: Our patient was a 32 year old African American man who had …

Introduction/Objective Only one prior case report indicates that mixed positive cryoglobulin in serum can be associated with intestinal vasculitis (Annals of Internal Medicine, 1974).

Methods/Case Report We report a 63-year old man with history of positive serum cryoglobulin and hepatitis-C 4 years ago and membranoproliferative pattern of glomerulonephritis with possible cryoglobulin type of deposits by electron microscopy on renal biopsy. After treatment, his hepatitis C became negative. But he was recently found to have monoclonal IgM-kappa and positive cryoglobulin in his serum, and the concurrent renal biopsy showed membranoproliferative pattern of glomerulopathy with many hyaline-thrombi (eosinophilic vascular occlusions with no …

Gata3 Is A Useful Immunohistochemical Marker To Differentiate Variants Of Renal Tubular Lesions From Different Segments Of Renal Tubules, M Deebajah, Z Qu, P Zhang

Conference Presentation Abstracts

Introduction/Objective GATA3 is found in glomerular mesangial cells, and the distal tubules & collecting ducts in metanephros and eventual kidneys, but not associated with the proximal tubules and loops of Henle. We hypothesize that GATA3 can be used as a marker to identify the origin of tubular differentiation in most renal tumors.

Methods/Case Report Ten negative controls and 43 renal mass lesions (RCC, papillary, clear cell papillary, and chromophobe carcinomas, oncocytoma, and polycystic kidney disease). GATA3 nuclear stain was graded as negative (absent stain), equivocal and positive (< 5 and > 5% cells, respectively). Details of their GATA3 nuclear expression was analyzed for …

Conference Presentation Abstracts

Introduction/Objective: IgG4 related disease, a systemic autoimmune inflammatory disorders, can be identified by high% of IgG4 positive plasma cells, thus IgG4 staining in paraffin embedded tissue is widely available in the most of pathology labs. IgG4 staining has been found useful to identify primary MGN (PLA2R and/or THSD7A positive) by others and us. This study was to scrutinize the findings of primary vs secondary MGN needed for IgG4 staining as a screening tool in our renal pathology practice over pasts 5 years Methods/Case Report: IgG4 staining in paraffin embedded tissue was performed in 45 primary MGN and 43 secondary MGN …

Increased Activated Plasma Cells In Inflammatory Bowel Disease When Compared To Ischemic Acute Colitis, C Thornburn, Z Qu, P Zhang

Conference Presentation Abstracts

Introduction/Objective Inflammatory bowel disease (IBD) and acute ischemic colitis can both be involved by active colitis. IBD is characterized by crypt architectural distortion, basal lymphoplasmacytosis, and occasional granulomatous changes. However, diagnosis of IBDs is still largely by exclusion of other types of active colitis with similar changes. We previously demonstrated that glucose regulated protein 94 (grp94) is mainly expressed by activated plasma cells. We postulate that increased numbers of grp94-positive plasma cells may support diagnosis of IBDs. Here, we compared IBD and active ischemic colitis for grp94 expression in mucosal plasma cells of colectomy specimens

Reimbursement Incentive Associated With Decreased Inpatient Opioid Prescribing Following Robotic Radical Prostatectomy, Brett Watson, Ross Touriel, Joshua Volin, Frank Burks

Conference Presentation Abstracts

Introduction: Various strategies have been explored to decrease the quantity of opioids prescribed for post-operative pain. The Michigan Opioid Prescribing Engagement Network, in partnership with BCBS-Michigan, has developed a pain optimization pathway for several surgical procedures, including prostatectomy. Urologists who follow the pain optimization pathway, which includes pre-operative patient education and limiting discharge opioids to 6 tablets of oxycodone 5 mg, can report a modifier for additional reimbursement. We explored the impact of this incentive on inpatient opioid prescribing practices following robotic assisted radical prostatectomy (RARP). Methods: Patients undergoing RARP between January 2017 and August 2019 at a single institution …

Perioperative Antibiotic Use In Neonatal General Surgery: A Survey Of Apsa Membership, Ashley Williams, Samuel K. Osei, Pavan Brahmamdam, Begum Akay, Diane Studzinski

Conference Presentation Abstracts

Background: Surgical site infections (SSIs) are a significant source of perioperative morbidity. There is limited data regarding antibiotic prophylaxis in pediatrics, and there are no standardized guidelines in neonates. Thus, peri-operative antibiotic use is based on surgeon experience and preference. To explore this knowledge gap, we sought to describe the practice patterns of pediatric surgeons with regard to antibiotic prophylaxis for SSIs in neonatal surgery

Methods: A survey was distributed to the American Pediatric Surgical Association (APSA). Members were asked to respond to 6 hypothetical case scenarios: Tracheoesophageal fistula/Esophageal atresia, Hirschsprung’s disease, Gastroschisis, Congenital diaphragmatic hernia repair, Neonatal intestinal obstruction …

Cost-Effectiveness Analysis Of Recombinant Zoster Vaccine For The Prevention Of Herpes Zoster In Immunocompromised Adults Diagnosed With Select Cancers In The United States, Desmond Curran, Brandon Patterson, Justin Carrico, Ahmed Salem, Elizabeth La, Stephane Lorenc, Katherine Hicks, Sara Poston, Christopher Carpenter

Conference Presentation Abstracts

Introduction / Background / Significance: Immunocompromised (IC) populations diagnosed with cancer are at increased risk for herpes zoster (HZ) due to their underlying disease and/or therapy. This risk is highest among individuals receiving hematopoietic stem cell transplant (HSCT) to treat multiple myeloma, lymphomas, or other diseases. HZ is characterized by a painful vesicular rash. IC populations with HZ are also at increased risk of developing HZ-related complications such as postherpetic neuralgia, a persistent pain that can last for months or years. This study evaluates the cost-effectiveness of recombinant zoster vaccine (RZV) versus no vaccine for the prevention of HZ in …
