Laparoscopic Warshaw procedure in pediatric solid pseudopapillary neoplasm of the pancreas: Technical feasibility and oncological outcomes. Asian J Endosc Surg 2024; 17:e13336. [PMID: 38923310 DOI: 10.1111/ases.13336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 05/26/2024] [Accepted: 06/03/2024] [Indexed: 06/28/2024]
Abstract
Achieving margin-negative resection is crucial in treatment of solid pseudopapillary neoplasm (SPN) of the pancreas, while preserving the spleen during distal pancreatectomy is highly desirable in pediatric cases. Laparoscopic Warshaw procedure (Lap-WT) is invaluable when tumor involvement in splenic vessels complicates preservation. However, the feasibility of Lap-WT in pediatric patients remains contentious. This study presents the clinical outcomes of three pediatric SPN cases who underwent Lap-WT. The median age was 10 years, with a median tumor size of 50 mm. Lap-WT demonstrated successful outcomes with a median operation time of 311 min and blood loss of 12 mL. No postoperative complications occurred, with a median length of hospital stay of 8 days. Long-term follow-up showed mild thrombocytopenia and increased spleen volume in two cases, perigastric varices in one, with no bleeding complications. No instances of tumor recurrence were observed. Lap-WT emerges as a feasible approach for pediatric SPN, ensuring spleen preservation without compromising oncological outcomes.

Role of endoscopic ultrasound-guided fine needle aspiration biopsies in diagnosing pancreatic neoplasms in the paediatric population: experience from a tertiary center and review of the literature. Radiol Oncol 2024; 58:78-86. [PMID: 38378032 PMCID: PMC10878772 DOI: 10.2478/raon-2024-0008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 10/07/2023] [Indexed: 02/22/2024] Open
Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle aspiration biopsy (EUS FNAB) is a well established diagnostic method in adult patients, but is rarely used in the paediatric population. The Clinical Department of Gastroenterology at the University Clinical Centre Ljubljana and the Department of Cytopathology at the Institute of Pathology, Faculty of Medicine, University of Ljubljana, Slovenia, have been closely collaborating on EUS FNAB since the introduction in 2010. The aim of the study was to review the cases of EUS FNAB of pancreatic neoplasms in children. PATIENTS AND METHODS In the digital archive of the Institute of Pathology (IP), Faculty of Medicine (FM), University of Ljubljana (UL), we found 6 cases of EUS FNAB in children, 3 had EUS FNAB of the pancreas, 2 of whom had a cytopathologic diagnosis of a tumour. In the first case, the lesion was ultrasonographically solid, and the cell sample contained branching papillary structures surrounded by aggregates of small cells with nuclear grooves. In the second case, the lesion was ultrasonographically cystic, and predominantly necrosis was seen, with only single preserved cells. Positive nuclear reaction for β-catenin was found in both cases by immunohistochemical staining. RESULTS In both cases, the cytopathological diagnosis of solid pseudopapillary neoplasm of the pancreas was made, the cases represent the totality of paediatric cases of pancreatic neoplasms from the Children's Hospital Ljubljana since 2010. There were no adverse events during and after EUS FNAB. A histopathological examination of the tumour resection specimens confirmed the cytopathological diagnosis. CONCLUSIONS Our experience indicates that EUS FNAB is a safe and effective method for diagnosing pancreatic neoplasms in the pediatric population, as supported by the findings in the literature.

Abstract
Pancreatic cancer is one of the most lethal malignant neoplasms, with a 1-year survival rate after diagnosis of 24%, and a 5-year survival rate of only 9%. While this illustrates the behavior of its main histologic type - ductal adenocarcinoma, there are other histologic subtypes of pancreatic cancer that can harbor excellent prognosis. Solid pseudopapillary neoplasm, described as a rare low-grade malignant neoplasm by the World Health Organization, is the best example of that, having an overall 5-year survival rate of about 97%. Not only the prognosis, but everything about this entity is unique: its histogenesis, epidemiology, presentation, imaging characteristics, cytology features, immunohistochemical profile, and treatment. This explains the urge to improve our understanding about this entity and thus our ability to accurately recognize and manage it. Having this in mind, this article aims to summarize the most relevant topics regarding this entity.

Abstract
BACKGROUND Solid pseudopapillary tumors (SPTs) of the pancreas arise rarely in children, are often large, and can associate intimately with splenic vessels. Splenic preservation is a fundamental consideration when resecting distal SPT. Occasionally, the main splenic vessels must be divided to resect the SPT with negative margins, but the spleen can be preserved if the short gastric vessels remain intact (ie, Warshaw procedure). The purpose of this study was to evaluate outcomes of distal pancreatectomy (DP) for SPT in children and to highlight 2 cases of splenic preservation using the Warshaw procedure. METHODS Patients 19 years and younger who were treated at a single children's hospital between July 2004 and January 2021 were examined. Patient characteristics were collected from the electronic medical record. A pediatric radiologist calculated SPT and pre- and post-operative (ie, non-infarcted) splenic volumes. RESULTS Eleven patients received DP for SPT. Six DPs were performed open and 5 laparoscopically. The spleen was preserved in 3 open and 4 laparoscopic DPs. A laparoscopic Warshaw procedure was performed in 2 patients. Laparoscopic resection associated with less frequent epidural use (P = .015), shorter time to full diet (P = .030), and post-operative length of stay (P = .009), compared to open resection. Average residual splenic volume after the laparoscopic Warshaw procedure was 70% of preoperative volume. DISCUSSION Laparoscopic DP for pediatric SPT achieved similar oncologic goals to open resection. Splenic preservation was feasible with laparoscopy in most cases and was successfully supplemented with the Warshaw procedure, which has not been previously reported for SPT resection in children.

[PMID: 35201506 PMCID: PMC8777513 DOI: 10.1007/s12672-021-00451-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 11/17/2021] [Indexed: 11/06/2022] Open
Abstract
PURPOSE Solid pseudopapillary neoplasm (SPN) is an uncommon pathology with a low-grade malignancy. Surgery is the milestone treatment. Nevertheless, despite appropriate management, some patients present recurrence. Risk factors associated with recurrence are unclear. The objective was to identify the clinicopathological factors associated with recurrence in patients with SPN treated with pancreatic resection. METHODS Medical records of patients treated with pancreatic resection during 2006-2020 were evaluated. Patients with histological diagnosis of SPN were included. Survival analysis was performed to identify the clinicopathological factors related to recurrence. RESULTS Seventy-four patients were diagnosed with SPN; 70 (94.6%) patients were female, and the median age was 20 years old. The median tumor diameter was 7.9 cm. Multivisceral resection was performed in 9 (12.2%) patients. Four (5.4%) patients presented lymph node metastasis.R0 resection was achieved in all cases. Six (8%) patients presented recurrence and the liver was the most frequent recurrence site (n = 5).After a median follow-up of 40.2 months, 9 (12%) patients died. Five (6.8%) patients died of disease progression. The 1-3- and 5-year overall survival (OS) was 97.1%, 90.2% and 79.9%, respectively. The 1-3-and-5-year recurrence-free survival (RFS) was 98.4%, 89.9% and 87%, respectively. In the univariate Cox-regression analysis, age ≥ 28 years(HR = 8.61, 95% CI 1.1-73.8),tumor diameter ≥ 10 cm(HR = 9.3, 95% CI 1.12-79.6),invasion of adjacent organs (HR = 7.45, 95% CI 1.5-36.9), lymph node metastasis (pN +) (HR = 16.8, 95% CI 2.96-94.9) and, AJCC Stage III (HR = 10.1, 95% CI 1.2-90.9) were identified as predictors for recurrence. CONCLUSIONS SPN is more frequently diagnosed in young women with a good overall prognosis after an R0 surgical resection even with disease recurrence. Age ≥ 28 years, larger tumors ≥ 10 cm, invasion of adjacent organs, lymph node metastasis(pN +) and, AJCC Stage III were predictors factors of recurrence in resected SPN.

Abstract
BACKGROUND Undifferentiated embryonal sarcoma of the liver (UESL) is a rare liver tumour that occurs mainly in children. Herein, we aimed to identify any differences in clinical characteristics and survival between adult and paediatric patients with UESL. METHODS From 1975 to 2015 in the Surveillance, Epidemiology and End Results (SEER) database, patients diagnosed with UESL were identified and divided into paediatric (<18 years) and adult (≥18 years) groups. We then compared the clinical characteristics, management, and overall survival (OS) of adults and children diagnosed with UESL. RESULTS We analysed 113 patients with UESL (81 children and 32 adults). UESL was significantly more common in adult male than paediatric male patients (71.9% vs. 48.2%; P = 0.022). When compared to adult patients, paediatric patients were more likely to receive chemotherapy (93.8% vs. 65.6%; P < 0.001). Adults had a significantly worse OS than paediatric patients (5-year OS, 30.0% vs. 81.2%; P < 0.001). Univariate analysis found that adult age, surgical therapy and chemotherapy were associated with OS. Multivariate analysis revealed that adult age, SEER summary stage and surgical therapy were independent prognostic factors for OS. CONCLUSIONS UESL had a male predominance among adult patients. Moreover, the prognosis of adult patients with UESL was significantly worse than that of paediatric patients. Surgery and chemotherapy should be considered in the treatment of patients with UESL.

Abstract
BACKGROUND Solid pseudopapillary tumors (SPTs) are rare, but they comprise the majority of pediatric pancreatic neoplasms. However, studies on these conditions in pediatric patients are lacking. The aim of this study was to investigate the clinical characteristics and treatment outcomes in children and adolescents with SPTs. METHODS This retrospective study included 51 patients with SPTs who had undergone pancreatic tumor resection before the age of 19 years at Samsung Medical Center in Korea (from November 1994 to August 2020). We investigated the postoperative outcomes. RESULTS Of the 51 patients with SPTs (female, 88.2%), the median age at diagnosis was 14 years (range, 8-19). The most common symptom was abdominal pain (60.8%), and 14 patients (27.5%) were asymptomatic. The median maximal tumor diameter was 7 cm (range, 1.4-14), and the pancreatic body and/or tail were involved in 68.6% of patients. The short-term complication rate was 21.5%, and the recurrence rate was 5.9%. New-onset diabetes mellitus (NODM) occurred in four patients. CONCLUSIONS The ideal treatment for SPTs is complete resection of the tumor; however, long-term postoperative complications including NODM should be monitored carefully, particularly in children and adolescents.

Abstract
Gastrointestinal stromal tumors and neuroendocrine tumors in adult and pediatric populations differ immensely. Despite these established differences, the extreme rarity of gastrointestinal stromal tumors and neuroendocrine tumors in the pediatric population has resulted in the lack of consensus management guidelines, making optimal surgical approaches unclear. Comprehensive management principles to guide surgical approaches in adult literature are extensive. However, these are still lacking for pediatric patients. International cooperation to develop standardized pediatric-specific guidelines is urgently warranted in the future. This article highlights the vast differences between adult and pediatric parameters and provides recommendations on optimal and novel surgical approaches in children.

Abstract
Presentation, diagnosis and management of SPEN of the pancreas, a rare pancreatic tumor. SPEN is more common in women and can be more locally invasive and aggressive in men. Treatment involves surgical resection of the tumor and follow-up for recurrence. It has an excellent prognosis following resection; hence early identification and treatment are essential.
Introduction and importance Solid Pseudopapillary Epithelial Neoplasm (SPEN) of the pancreas is a rare cystic exocrine tumor of the pancreas most commonly occurring in women between 30 and 40 years of age. This case report aims to demonstrate the clinicopathological findings encountered and the management of a patient diagnosed with SPEN. Case presentation An 18-year-old woman with gradually progressive and intermittent abdominal pain in the epigastric region presented to our outpatient department. Physical examination elicited tenderness to palpation in the epigastric area, and imaging findings suggested SPEN of the pancreas involving distal body and proximal tail region of the pancreas. The tumor was resected, and the diagnosis was confirmed on histopathology examination. Clinical discussion SPEN is a slow-growing tumor with a low-grade malignant potential, found incidentally in asymptomatic patients and symptomatic patients present with abdominal pain. The average tumor size is about 4 to 6 cm in diameter. Imaging is essential for diagnosis, and distal pancreatectomy with splenectomy was the most commonly reported procedure. Conclusion It is crucial to consider a diagnosis of SPEN in women with abdominal pain in the epigastric region as early surgical resection of the tumor results in resolution and excellent prognosis.

Abstract
Background Pancreatic Solid Pseudopapillary Neoplasms (SPNs) are rare low-grade malignant tumors with a marked preponderance for young females. Objective was to describe the morphology, differential diagnosis, and prognosis of SPNs in patients under 20 years of age and present a detailed review of literature. Methods A total of 29 cases in patients under 20 years of age reported as SPN during the period January 2014 to December 2019, were included in the study. These included 19 resection specimens, 4 incision biopsies and 6 cases received as blocks for second opinion. Hematoxylin and eosin (H&E) slides as well as immunohistochemistry (IHC) slides of all cases were retrieved and reviewed by the authors. TFE3 and Progesterone Receptor were performed retrospectively. Results Twenty-eight of the 29 patients were females. Ages of patients ranged from 12 to 19 years. Nineteen cases were resections. Tail was the commonest location. Mean tumor size was 9.5 cm. In 89.5% cases, tumor was confined to the pancreas. In 2 cases, distant metastasis was present. In 2 cases, extension beyond pancreas was seen. Solid and pseudopapillary areas were seen in all cases while other features were variable. Beta catenin and Cyclin D1 were positive in most cases while TFE3 was positive in 57% cases. Progesterone Receptor (PR) was positive in all 13 cases in which it was performed. Follow up was available in 14 patients. Follow up period ranged from 3 to 70 months. Twelve were alive and well without recurrence or metastasis while 2 were alive with recurrence and metastasis to liver and omentum respectively. Conclusions Although many studies on SPNs have been published, surgeons, oncologists and even pathologists in this part of the world are often not aware of these rare tumors leading to inaccuracies and delays in diagnosis. In addition, this paper focusses on the interesting observation that the majority of SPNs diagnosed in our department during study period occurred in patients under 20 years of age (29 versus 21 in patients over 20). However, clinico-epidemiological, morphologic and prognostic features were similar in both age groups. Possibility of SPNs should always be considered in case of pancreatic neoplasms occurring in patients under 20 years of age as well. We believe that this is a very interesting and helpful study for the clinicians as well as the pathologists.

Abstract
Solid pseudopapillary tumors (SPTs) constitute 0.2 to 2.7% of non-endocrine primary tumors of the pancreas and comprise the majority (70%) of pediatric pancreatic neoplasms. These tumors are of unclear pathogenesis, low malignancy and favorable prognosis. Surgical resection offers an excellent chance for longterm survival, even in the presence of distant metastasis. The objective of this study is to review our experience in the management of SPT in a 12 years old girl at the pediatric hospital of the University hospital of Casablanca, in Morocco and provide an update on current management in pediatric population.
