RESUMEN
Askin tumors are the rare malignancy of neuroectodermal origin of the thoracic wall. Its prevalence is more in younger age group who present with vague symptoms leading to delayed diagnosis. We hereby present a case report of complex management of large chest wall tumor in a young boy and review the literature of this entity.
RESUMEN
Duodenal lipoma is a very rare entity with limited case reports present in literature. But duodenal ampullary lipomas are even more rare in nature. Owing to the recent advances in endoscopy and modern imaging techniques, more cases are being diagnosed and treated. However, challenge lies in performing a less invasive and least morbid procedures to treat them surgically in such complex location of tumour. To study the diagnosis and treatment of duodenal ampullary lipoma in a young male patient and challenges faced during surgical management. A 15-year-old young boy presented to us with complaints of intermittent upper gastrointestinal bleed and jaundice since last 2 months. At admission, his serum haemoglobin was 3 g% for which he was transfused 3 units of packed blood cells for optimization. On further evaluation, CT scan abdomen revealed 71 × 49 mm large heterogeneous mass in D3 segment of duodenum causing duodeno-duodenal intussusception involving D1 and D2 segment along with ampullary region with mass being the lead point. There was compression of CBD with dilatation measuring 11 mm in diameter and mild IHBR dilatation. UGIE revealed narrowing at D1-D2 junction due to polypoidal lesion with overlying smooth mucosa with no active bleeding point identified. His blood parameters were normal except for low haemoglobin (before blood transfusion) and total serum bilirubin of 2.3 mg/dl.He was optimized for surgery and underwent exploratory laparotomy with duodenotomy at D2 with mass excision of 7 × 5 cm sessile polyp with base over ampulla followed by plastic repair of sphincter of Oddi (pancreas preserving procedure). He was started on oral liquids on POD 3 and was discharged on normal diet by POD 7 with an uneventful recovery. Result of histopathological report revealed, on gross cut section, the presence of mass of 7 × 5 × 3 cm size with smooth mucosa and fibrofatty tissue. On microscopic examination, diagnosis of submucosal lipomatous polyp was made. Our case report indicated duodenal ampullary lipoma is extremely rare entity. The symptoms are nonspecific and CT scan abdomen is the first investigation of choice for diagnosis. The treatment depends on the patient's condition as well as the size and position of the tumour. In our case report, the tumour base was exactly at the level of ampulla where we performed complex procedure of local excision of mass with sphincteroplasty avoiding major Whipple procedure for such benign condition. It provided rapid postoperative recovery to the patient.
RESUMEN
Fibromatosis is a rare locally aggressive benign tumour which arises from the musculoaponeurotic structures throughout the body. In the oral and maxillofacial region, It has been described under a variety of synonyms, including 'extra articular desmoids', 'desmoids tumours', 'grade-1 fibrosarcomas','non metastasizing fibrosarcoma'and 'aggressive fibromatosis'. The pecularity of this entity in paranasal sinuses is that it is rare in this location and are locally aggressive with higher rates of recurrence in a relatively restricted area.The purpose of this study is to present a rare case report and reviewing the literature of this entity.
RESUMEN
More women with mechanical mitral valves (MMVs) are pursuing pregnancy. Guidelines exist for pregnancy anticoagulation, but they do not address individualized anticoagulation during delivery-a period of risk for bleeding, thrombosis, and anesthetic complications. This case series of parturients with MMVs highlights the challenges in, and the evidence and strategies for, treating these patients. (Level of Difficulty: Advanced.).
RESUMEN
Background: Giant cystic meconium peritonitis (MP) is a relatively rare entity. Prompt surgical treatment is required to manage the underlying etiology and reestablish the continuity of the intestines. Despite perinatal and postoperative care improvements, the overall mortality rate is still relatively high. We reported a giant cystic MP that was recognized using antenatal sonography (US). It was successfully treated with primary anastomosis. Case presentation: We presented a female newborn with a chief complaint of abdominal mass. The prenatal sonography showed an intraabdominal cyst at the 28th week of gestation. She was born at the gestational age of 38 weeks via vaginal delivery from a primigravid mother without complications, with a birth weight of 3275 g. Elective surgery was performed at the age of eight days, and a calcified 10 cm cyst was revealed along with severe adhesions. The cyst was found to communicate with the ileum located 30 cm proximal from the ileocecal junction. No malrotation and volvulus were found. The cyst and a portion of the ileum were resected, followed by a primary end-to-end anastomosis. Pathologic examination showed necrotic tissue lined with epithelial tissue with microcalcifications containing bilirubin pigments, consistent with cystic MP. The patient has uneventfully discharged on postoperative day 17. The patient has normal growth and development, except for delayed walking, at the last follow-up of two years of age. Conclusion: Giant cystic MP is a rare disorder that can be detected early using the antenatal US. Our case highlights the importance of early diagnosis for giant cystic MP using the antenatal US leads to prompt surgical treatment and a more favorable prognosis.

RESUMEN
Ectopic ureters are rare congenital malformations of the urinary tract, more frequent in females and most commonly associated with single collecting system in males. We report a case of a prostate cancer patient undergoing robotically assisted laparoscopic radical prostatectomy. Duplication of vas deferens was thought to be found during surgery. Postoperatively, patient developed fevers. CT showed incidental finding of duplex collecting system on the left with dilatation of the upper moiety. Percutaneous nephrostomy was placed but an attempt at antegrade insertion of ureteric stent was unsuccessful. Robotic reimplantation of the ectopic ureter was successfully performed on day six post prostatectomy.

RESUMEN
Background: Development of sepsis is a major contributor to poor outcomes after liver transplant. The neutrophil-lymphocyte ratio (NLR) is an easily calculable inflammatory biomarker. We aim to utilize NLR to diagnose and predict the onset of sepsis in patients undergoing living donor liver transplants (LDLT). Materials and methods: Analysis of the perioperative course of 314 consecutive adult patients who underwent elective ABO compatible LDLT was done. Patients were divided into two cohorts; those who developed sepsis and a control group. Sepsis was defined by the combination of SIRS and clinical/radiological suspicion of infection. NLR was calculated by dividing the percentage of neutrophils by the percentage of lymphocytes in peripheral blood. Results: ostoperatively, 127 out of 314 patients (40.5%) having at least one episode of sepsis were included in the septic cohort and were compared to the 187 (59.5%) patients in the control group. Demographic and baseline characteristics, including NLR (13.74 ± 0.99 vs. 12.65 ± 0.57, P = 0.294) were comparable preoperatively. The NLR of the septic cohort was significantly higher than the control cohort (15.01 ± 1.67 vs. 9.98 ± 0.63, P = 0.001) 3 days prior to sepsis and remained significantly higher till the day of sepsis. The area under the cover was maximum for NLR 1 day prior to the development of sepsis (r = 0.707) with a sensitivity, specificity, positive predictive value, and negative predictive value of 62.4%, 62.2%, 51.4%, and 72.0%, respectively, at a cutoff of 8.5. Conclusion: NLR is a useful tool in diagnosing and pre-empting development of sepsis in LDLT.

RESUMEN
Background: Obstructive cholestasis can lead to significant alterations of the biliary tree depending on the extent and duration of the biliary occlusion. Current experimental studies reported about advanced techniques for corrosion cast and 3D reconstruction (3D-reco) visualizing delicate microvascular structures in animals. We compared these two different techniques for visualization and quantitative assessment of the obstructed murine biliary tree with classical 2D histology. Methods: Male mice (n = 36) were allocated to 3 different experiments. In experiments 1 and 2, we injected two different media (Microfil© for 3D-reco, MV; Batson's No.17 for corrosion cast, CC) into the extrahepatic bile duct. In experiment 3 we sampled liver tissue for 2D histology (HE, BrdU). Time points of interest were days 1, 3, 5, 7, 14, and 28 after biliary occlusion. We used different types of software for quantification of the different samples: IMALYTICS Preclinical for 3D scans (MV); NDP.view2 for the digital photography of CC; HistoKat software for 2D histology. Results: We achieved samples in 75% of the animals suitable for evaluation (MV and CC, each with 9/12). Contrasting of terminal bile ducts (4th order of branches) was achieved with either technique. MV permitted a fast 3D-reco of the hierarchy of the biliary tree, including the 3rd and 4th order of branches in almost all samples (8/9 and 6/9). CC enabled focused evaluation of the hierarchy of the biliary tree, including the 4th to 5th order of branches in almost all samples (9/9 and 8/9). In addition, we detected dense meshes of the smallest bile ducts in almost all CC samples (8/9). MV and CC allowed a quantitative assessment of anatomical details of the 3rd and 4th order branches of almost every sample. The 2D histology identified different kinetics and areas of proliferation of hepatocytes and cholangiocytes. Complementary usage of 3D-reco, corrosion casting and 2D histology matched dense meshes of small bile ducts with areas of intensive proliferative activity of cholangiocytes as periportal proliferative areas of 4th and 5th order branches (â¼terminal bile ducts and bile ductules) matched with its morphological information the matching assessment of areas with increased proliferative activity (BrdU) and a partial quantification of the characteristics of the 4th order branches of the biliary tree. Conclusion: The 3D-reco and corrosion casting of the murine biliary tree are feasible and provide a straightforward, robust, and reliable (and more economical) procedure for the visualization and quantitative assessment of architectural alterations, in comparative usage with the 2D histology.

RESUMEN
The management of type A aortic dissection (TAAD) during transcatheter aortic valve replacement (TAVR) is challenging because TAVR is often performed in elderly patients with significant surgical risk. We present a case of extensive TAAD that developed during the TAVR procedure, which resolved spontaneously with medical treatment. (Level of Difficulty: Intermediate).
RESUMEN
The clinical course after liver transplantation (LT) in progressive familial intrahepatic cholestasis type 1 (PFIC1) is complicated by intractable diarrhoea, growth failure, graft steatosis and cirrhosis. Recent evidence from Japan suggests the role of genotype to predict outcome after LT. We report a case with pathogenic frameshift mutation who had failed partial external biliary diversion, underwent LT and his post-LT course has been complicated by intractable diarrhoea, growth failure, steatosis and fibrosis. This case highlights the fact that homozygous frameshift p.Gly197LeufsTer10 mutation in ATP8B1 is associated with poor outcome and genetic evaluation should be mandatory before subjecting the patient to LT.
RESUMEN
Liver tumours are uncommon in the paediatric population, constituting 1-2 % of all paediatric tumours and 4% of all paediatric liver tumours. Hepatoblastoma followed by hepatocellular carcinoma is the most common tumours in this age group. Simultaneous development of two discrete liver tumours of distinct histologies (collision tumour) has been occasionally reported in adults but never in children. We hereby present the first reported case of hepatic collision tumours (hepatocellular carcinoma and cholangiocarcinoma) in the explant liver of a child who underwent living donor liver transplantation for end-stage liver disease and severe hepatopulmonary syndrome. The manuscript describes the clinical, radiological and histopathological findings of this case and also highlights the dilemma associated with management of this case had the diagnosis been made in the preoperative setting and also about the proposed management plan for this case in the postoperative period.
RESUMEN
Coronavirus disease 2019 (COVID-19), a novel etiology of end-stage lung disease, has resulted in major disruptions to the process of health care delivery worldwide. These disruptions have led to team-based innovations globally, resulting in a broad range of new processes in cardiopulmonary perioperative management. A key intersection of multidisciplinary teamwork and COVID-19 is found in lung transplantation, in which diverse teams collaborate throughout the perioperative period to achieve optimal outcomes. In this article, we describe the multidisciplinary approach taken by Mayo clinic in Florida to manage patients with COVID-19 presenting for lung transplantation.
RESUMEN

Acute postoperative aortic dissection in pediatric patients can be life-threatening. We performed a novel hybrid transcarotid covered stent exclusion of a postoperative ascending aortic dissection in an infant. (Level of Difficulty: Advanced.).
RESUMEN
BACKGROUND: An ideal definition of early allograft dysfunction (EAD) after live donor liver transplantation (LDLT) remains elusive. The aim of the present study was to compare the diagnostic accuracies of existing EAD definitions, identify the predictors of early graft loss due to EAD, and formulate a new definition, estimating EAD-related mortality in LDLT recipients. METHODS: Consecutive adult patients undergoing elective LDLT were analyzed. Patients with technical (vascular, biliary) complications and biopsy-proven rejections were excluded. RESULTS: There were 19 deaths due to EAD of a total of 304 patients. On applying the existing definitions of EAD, we revealed their limitations of being either too broad with low specificity or too restrictive with low sensitivity in patients with LDLT. A new definition of EAD-LDLT (total bilirubin >10 mg/dL, international normalized ratio [INR] > 1.6 and serum urea >100 mg/dL, for five consecutive days after day 7) was derived after doing a multivariate analysis. In receiver operator characteristics analysis, an AUC for EAD-LDLT was 0.86. The calibration and internal cross-validation of the new model confirmed its predictability. CONCLUSION: The new model of EAD-LDLT, based on total bilirubin >10 mg/dL, INR >1.6 and serum urea >100 mg/dL, for five consecutive days after day 7, has a better predictive value for mortality due to EAD in LDLT recipients.
