Manejo quirúrgico de pseudoquiste pancreático gigante: caso clínico / Surgical management of giant pancreatic pseudocyst: case report

Resumen Introducción: Los pseudoquistes pancreáticos (PQP) corresponden al 80% de las lesiones quísticas del páncreas. Se debe descartar un tumor quístico, que representan el 10% al 15% de los quistes del páncreas y 1% de los tumores malignos por lo que es fundamental el estudio y diagnóstico diferencial. El término pseudoquiste pancreático gigante se usa tradicionalmente cuando el tamaño es mayor de 10 cm. Hay pocos casos de PQP gigantes en la literatura nacional. Objetivo: Reportar caso clínico con PQP gigante, analizar el diagnóstico diferencial y las opciones terapéuticas. Materiales y Método: Paciente con distensión abdominal progresiva, pérdida de peso y anorexia, posepisodio de pancreatitis aguda. Tomografía computarizada abdominal y resonancia magnética confirman lesión quística gigante intraabdominal. El paciente fue tratado con una cistoyeyunostomía pancreática abierta en Y de Roux. El análisis del contenido aspirado durante la cirugía sugiere PQP. Para la discusión se revisa la literatura más relevante. Resultados: Excelente resultado clínico postoperatorio, el estudio histopatológico de la pared del quiste confirmó el diagnóstico de pseudoquiste pancreático. Al año de seguimiento, el paciente permanece asintomático. Discusión: El estudio preoperatorio es crucial para determinar el diagnóstico diferencial y descartar lesiones neoplásicas o parasitarias quísticas. Los PSQ gigantes reportados son poco frecuentes y su manejo quirúrgico dependerá fundamentalmente de su tamaño, de las relaciones anatómicas y de la experiencia del equipo tratante.

Introduction: Pancreatic pseudocysts (PQP) correspond to 80% of cystic lesions of the pancreas. A cystic tumor must be ruled out, which represents 10% to 15% of pancreatic cysts and 1% of malignant tumors, so the study and differential diagnosis is essential. The term giant pancreatic pseudocyst is traditionally used when the size is greater than 10 cm. There are few cases of giant PQP in the national literature. Objective: To report a clinical case with giant PQP, to analyze the differential diagnosis and therapeutic options. Materials and Method: Patient with progressive abdominal distension, weight loss and anorexia post episode of acute pancreatitis. Abdominal computed tomography and magnetic resonance imaging confirm a giant intra-abdominal cystic lesion. The patient was treated with an open Roux-en-Y pancreatic cysto-jejunostomy. Analysis of the content aspirated during surgery suggests PQP. The most relevant literature is reviewed for discussion. Results: Excellent postoperative clinical results, the histopathological study of the cyst wall, confirmed the diagnosis of pancreatic pseudocyst. At one year of follow-up, the patient remains asymptomatic. Discussion: The preoperative study is crucial to determine the differential diagnosis and rule out neoplastic or cystic parasitic lesions. Reported giant PSQs are rare and their surgical management will depend fundamentally on their size, anatomical relationships, and the experience of the treating team.

Efficacy and safety of endoscopic ultrasound-guided drainage of pancreatic pseudocysts using double-pigtail plastic stents: A single tertiary center experience

OBJECTIVES: Pancreatic pseudocysts (PPC) are fluid collections with a well-defined wall that persist for more than 4 weeks inside or around the pancreas as a result of pancreatic inflammation and/or a ductal lesion. PPC have been successfully treated with endoscopic ultrasound (EUS)-guided drainage using different stents. This study aimed to evaluate the safety and efficacy of EUS-guided drainage of PPC using double-pigtail plastic stents in a tertiary hospital. METHODS: Patients with PPC referred for EUS-guided drainage between May 2015 and December 2019 were included in this case series. The primary endpoint was to evaluate the efficacy (clinical success) and safety (adverse events and mortality) of EUS-guided drainage of PPC. Secondary endpoints included technical success and pseudocyst recurrence. RESULTS: Eleven patients (mean age, 44.5±18.98 years) were included in this study. The etiologies for PPC were acute biliary pancreatitis, chronic alcoholic pancreatitis, and blunt abdominal trauma. The mean pseudocyst size was 9.4±2.69 cm. The clinical success rate was 91% (10/11). Adverse events occurred in three of 11 patients (27%). There were no cases of mortality. The technical success rate was 100%. Pseudocyst recurrence was identified in one of 11 patients (9%) at 12 weeks after successful clinical drainage and complete pseudocyst resolution. CONCLUSION: EUS-guided transmural drainage of PPC using double-pigtail plastic stents is safe and effective with high technical and clinical success rates.

Neoplasia sólida pseudopapilar pancreática: comunicación de cuatro casos clínicos y revisión de la literatura / Solid pseudopapillary tumor of the pancreas: four case reports and a review of the lilerature / Neoplasia sólida pseudopapilar pancreática: comunicação de quatro casos clínicos e revisão da literatura

Los tumores pseudopapilares del páncreas son tumores de origen pancreático poco frecuentes y de etiología desconocida. Comprenden entre el 0.2 y 2.7% de los carcinomas de páncreas. Hasta 2015 hay 900 casos reportados en la literatura, siendo una minoría en etapa diseminada. Son tumores voluminosos, de bajo potencial maligno, que se presentan con mayor frecuencia en mujeres jóvenes entre 18 y 35 años. Generalmente son asintomáticos o manifiestan clínicamente síntomas inespecíficos como dolor abdominal o presencia de masa abdominal. Anatómicamente se localizan con mayor frecuencia en la cola del páncreas, seguidos por la cabeza y el cuerpo. El tratamiento de elección es la resección quirúrgica. El rol de la quimioterapia en la enfermedad irresecable o avanzada no está claramente definido. Son tumores de excelente pronóstico, con sobrevida a 5 años de casi 100%.Se presentan cuatro casos clínicos y se hace una revisión de la literatura.

Pseudopapillary tumors of the pancreas are tumors of pancreatic origin with a low frequency and an unknown etiology. They account for 0.2 - 2.7 % of all pancreatic carcinomas. Up to 2015 there were approximately 900 well documented cases with only a small minority of them in a metastatic stage. This tumors could reach large proportions and they occur predominantly in young women between 18 and 35 years of age. Most of patients are asymptomatic or have non specific symptoms including abdominal pain or palpable abdominal mass. The most common localization is the tail of the pancreas, followed by the head and the body. Complete resection is the treatment of choice. It is not clearly stablished the rol of chemotherapy in metastatic disease. There are tumors with a favorable prognosis, with an overall 5 year survival rate about 95%. Herein, we report four clinical cases and a literatura review.

Pseudoquiste pancreático post-traumático en tauromaquia / Traumatic pancreatic pseudocyst in the tauromaquia

Aim: Here we present a case associated with closed abdominal trauma. Case report: Male 21 years old with history of abdominal trauma when riding a bull, managed conservatively with analgesics and antibiotics. Two months later he presented an abdominal painful mass located in epigastrium and middle abdomen. Abdominal USG and CT scan showed the presence of a tumor dependent of the pancreatic tail, with regular margins, compatible with pancreatic pseudocyst; surgical management was decided performing cystogastro anastomosis. Conclusion: This clinical report represent traumatic origin of some pancreatic pseudocysts, surgical indication needs to be personalized.

Objetivo: Presentamos aquí un caso de pseudoquiste de páncreas asociado a traumatismo abdominal cerrado. Caso clínico: Paciente masculino de 21 años de edad que recibe traumatismo directo sobre abdomen por un toro y es manejado de forma conservadora con analgésicos y antibióticos. Dos meses después presenta nuevamente dolor abdominal y aumento de volumen en epigastrio y mesogastrio. El ultrasonido y la TC abdominal evidencian imagen compatible con pseudoquiste pancreático realizándose cistogastroanastomosis. Conclusión: El caso representa la etiología traumática de algunos pseudoquistes de páncreas; las indicaciones quirúrgicas necesitan ser individualizadas.

Endoscopic Ultrasound-Guided Transluminal Drainage for Peripancreatic Fluid Collections: Where Are We Now?

Endoscopic drainage for pancreatic and peripancreatic fluid collections (PFCs) has been increasingly used as a minimally invasive alternative to surgical or percutaneous drainage. Recently, endoscopic ultrasound-guided transluminal drainage (EUS-TD) has become the standard of care and a safe procedure for nonsurgical PFC treatment. EUS-TD ensures a safe puncture, avoiding intervening blood vessels. Single or multiple plastic stents (combined with a nasocystic catheter) were used for the treatment of PFCs for EUS-TD. More recently, the use of covered self-expandable metallic stents (CSEMSs) has provided a safer and more efficient approach route for internal drainage. We focused our review on the best approach and stent to use in endoscopic drainage for PFCs. We reviewed studies of EUS-TD for PFCs based on the original Atlanta Classification, including case reports, case series, and previous review articles. Data on clinical outcomes and adverse events were collected retrospectively. A total of 93 patients underwent EUS-TD of pancreatic pseudocysts using CSEMSs. The treatment success and adverse event rates were 94.6% and 21.1%, respectively. The majority of complications were of mild severity and resolved with conservative therapy. A total of 56 patients underwent EUS-TD using CSEMSs for pancreatic abscesses or infected walled-off necroses. The treatment success and adverse event rates were 87.8% and 9.5%, respectively. EUS-TD can be performed safely and efficiently for PFC treatment. Larger diameter CSEMSs without additional fistula tract dilation for the passage of a standard scope are needed to access and drain for PFCs with solid debris.

Pseudoquiste pancreático fistulizado a vía biliar principal / Fistula formation between a pancreatic pseudocyst and the biliary tree

Introduction: Fistula formation between a pancreatic pseudocyst and the biliary tree is uncommon. Clinical case: We report a 71 years old female who developed a pancreatic pseudocyst secondary to a biliary acute pancreatitis. After eight weeks of evolution, the patient was operated due to the size of the pseudocyst and the presence of symptoms. During the operation, a fistula between the cyst and the biliary tree was found. It was successfully excluded performing a choledochostomy with a Kehr tube and pseudocyst drainage. The patient had an uneventful postoperative evolution and imaging studies at the moment of discharge, one month after the operation, did not show a residual cavity...

Introducción: Los pseudoquistes pancreáticos pueden desarrollarse tras episodios de pancreatitis, pudiendo originar diversas complicaciones como infección, hemorragia, fenómenos compresivos o fístulas pancreáticas. En el caso de estas últimas, la comunicación de un pseudoquiste pancreático a la vía biliar es una rareza, existiendo hasta la fecha sólo 19 casos reportados en la literatura. Caso clínico: Presentamos el caso de una paciente de 71 años que desarrolló un pseudoquiste pancreático posterior a pancreatitis aguda biliar y que debido a su tamaño y síntomas se decide el tratamiento quirúrgico a las 8 semanas. Durante la cirugía se diagnostica una fístula entre el pseudoquiste y la vía biliar principal, realizándose exclusión exitosa con coledocostomía con sonda Kehr, colecistectomía y drenaje del pseudoquiste, debido a la imposibilidad de derivación al tubo digestivo por friabilidad de su pared. La paciente evoluciona favorablemente, siendo dada de alta al mes de la cirugía. El control con imágenes previo al alta revela la desaparición del pseudoquiste, sin cavidad residual...

Pseudoquiste de páncreas con extensión a mediastino / Pancreatic pseudocyst extended to the mediastinum: case report

We report a 53 years old male consulting for chest pain and dyspnea. On physical examination, an epigastric mass was detected. A TC scan showed a collection located in the omental bursa, which protruded over the posterior gastric wall and ascended to the mediastinum. Due to the presence of pancreatic calcifications, a pancreatic pseudocyst was suspected. The mediastinal cyst was drained percutaneously, leaving pig tail drainage in the cavity. Afterwards a cyst excision and Roux en Y gastrostomy was performed. After the surgical procedure the cyst became infected, requiring antimicrobials. After two weeks he was discharged in good conditions.

Los pseudoquistes de páncreas representan el 75 por ciento de las lesiones quísticas del páncreas y generalmente se circunscriben en el abdomen. Se presenta el caso de un paciente con un pseudoquiste de páncreas con extensión transhiatal a mediastino. Estos casos deben sospecharse mediante una historia clínica detallada y preguntando por antecedentes de dolor abdominal previo porque la clínica con la que se suelen manifestar es muy poco específica. El tratamiento de los pseudoquistes con extensión a mediastino debería ser el drenaje definitivo, bien de forma quirúrgica o endoscópica.

Endoscopic Therapy in Chronic Pancreatitis

Chronic pancreatitis (CP) is a debilitating disease that can result in chronic abdominal pain, malnutrition, and other related complications. The main aims of treatment are to control symptoms, prevent disease progression, and correct any complications. A multidisciplinary approach involving medical, endoscopic, and surgical therapy is important. Endoscopic therapy plays a specific role in carefully selected patients as primary interventional therapy when medical measures fail or in patients who are not suitable for surgery. Endoscopic therapy is also used as a bridge to surgery or as a means to assess the potential response to pancreatic surgery. This review addresses the role of endoscopic therapy in relief of obstruction of the pancreatic duct (PD) and bile du ct, closure of PD leaks, and drainage of pseudocysts in CP. The role of endoscopic ultrasound-guided celiac plexus block for pain in chronic pancreatitis is also discussed.

Pancreatic Pseudocyst in Federal Medical Centre; Gombe and Review of Literature

Pseudocyst arises from pancreatic inflammation or ductal disruption and is the commonest cystic lesion of the pancreas. Although spontaneous resolution is common particularly in its early phase; progression of the cyst may culminate in grave consequences for the patient. The aim of the study is to highlight the presentation; management and outcome of pseudocyst in an environment where it is reportedly uncommon. Case series with review of literature. Although pancreatic pseudocyst is not very frequently seen in this environment; it is not entirely rare but is frequently misdiagnosed. Non specific symptoms in the early stage and subsequent confusion with various intra abdominal pathologies are among the reasons for late diagnosis and delayed intervention. Pseudocyst is amenable to surgical treatment. Early recognition is imperative in preventing complications and in defining the true incidence of this disease entity in our locality. Clinical suspicion in every setting of pancreatitis complemented by serum amylase estimations and early ultrasound scan will improve the diagnosis

Update on Endoscopic Treatment of Chronic Pancreatitis

Endoscopic therapy has been increasingly recognized as the effective therapy in selected patients with chronic pancreatitis. Utility of endotherapy in various conditions occurring in chronic pancreatitis is discussed. Its efficacy, limitations, and alternatives are addressed. For the best management of these complex entities, a multidisciplinary approach involving expertise in all pancreatic specialties is essential to achieve the goal.

Endoscopic ultrasound-guided endoscopic transmural drainage of pancreatic pseudocysts

BACKGROUND: Surgery is the traditional treatment for symptomatic pancreatic pseudocysts, but the morbidity is still too high. Minimally invasive endoscopic approaches have been encouraged. AIMS: To evaluate the efficacy of endoscopic ultrasound-guided endoscopic transmural drainage of pancreatic pseudocysts. METHODS: From January, 2003 to August, 2006, 31 consecutive symptomatic patients submitted to 37 procedures at the same endoscopic unit were retrospectively analysed. Chronic and acute pancreatitis were found in, respectively, 17 (54.8 percent) and 10 (32.3 percent) cases. Bulging was present in 14 (37.8 percent) cases. Cystogastrostomy or cystoduodenostomy were created with an interventional linear echoendoscope under endosonographic and fluoroscopic control. By protocol, only a single plastic stent, without nasocystic drain, was used. Straight or double pigtail stents were used in, respectively, 22 (59.5 percent) and 15 (40.5 percent) procedures. RESULTS: Endoscopic ultrasound-guided transmural drainage was successful in 29 (93.5 percent) patients. Two cases needed surgery, both due to procedure-related complications. There was no mortality related to the procedure. Twenty-four patients were followed-up longer than 4 weeks. During a mean follow-up of 12.6 months, there were six (25 percent) symptomatic recurrences due to stent clogging or migration, with two secondary infections. Median time for developing complications and recurrence of the collections was 3 weeks. These cases were successfully managed with new stents. Complications were more frequent in patients treated with straight stents and in those with a recent episode of acute pancreatitis. CONCLUSIONS: Endoscopic transmural drainage provides an effective approach to the management of pancreatic pseudocysts.

RACIONAL: A abordagem cirúrgica é o tratamento tradicional para os pseudocistos sintomáticos de pâncreas, contudo a morbidade permanece elevada. Terapêuticas endoscópicas minimamente invasivas têm sido encorajadas. OBJETIVO: Avaliar a eficácia da drenagem endoscópica transmural de pseudocistos de pâncreas guiada por ecoendoscopia. MÉTODOS: De janeiro de 2003 a agosto de 2006, 31 pacientes sintomáticos submetidos a 37 procedimentos no mesmo centro de referência foram analisados retrospectivamente. Pancreatite crônica e aguda foram detectadas em, respectivamente, 17 (54,8 por cento) e 10 (32,3 por cento) pacientes. Abaulamento da parede esteve presente em 14 (37,8 por cento) casos. Cistogastrostomias ou cistoduodenostomias foram criadas com um ecoendoscópio linear sob controle endosonográfico e fluoroscópico. Como rotina, apenas uma única prótese plástica foi empregada, sem dreno nasocístico. Próteses retas ou " double pigtail" foram empregadas em, respectivamente, 22 (59,5 por cento) e 15 (40,5 por cento) procedimentos. RESULTADOS: A drenagem endoscópica foi adequada em 29 (93,5 por cento) pacientes. Dois casos necessitaram intervenção cirúrgica por complicações do procedimento. Não houve mortalidade relacionada ao procedimento. Vinte e quatro pacientes contaram com seguimento superior a 4 semanas. Durante seguimento médio de 12,6 meses, ocorreram seis (25 por cento) recurrências sintomáticas por obstrução ou migração da prótese, com infecção secundária em dois casos, todos manejados com novas próteses. O tempo mediano para ocorrência de complicações foi de 3 semanas. Complicações tardias foram mais freqüentes em pacientes tratados com próteses retas e naqueles com história recente de pancreatite aguda. CONCLUSÔES: A drenagem endoscópica transmural constitui abordagem efetiva para o manejo dos pseudocistos de pâncreas.

Cistogastroanastomosis de pseudoquiste pancreático multilobulado / Cystogastricanastomosis of pseudocyst multilobulated pancreatic

Los pseudoquistes pancreáticos son colecciones pancreáticas encapsuladas por tejido fibroso. La incidencia luego de una pancreatitis es variable y cuando son de etiología por abuso de alcohol son más frecuentes los pseudoquistes múltiples. Ante la evolución, tamaño o complicación del pseudoquiste el tratamiento es quirúrgico, ya sea por vía endoscópica o por cirugía abierta. Se presenta un caso clínico de paciente con gran pseudoquiste multilobulado que requirió cistogastroanastomosis.

The pancreatic pseudocyst is a pancreatic fluid collection encapsulated by fibrous tissue. The incidence after pancreatitis is variable and if the etiology is secondary to alcohol abuse is more frequent the multiple pseudocyst. Depending of the evolution, size or complication of the pseudocyst, the treatment may be endoscopic or open surgery. A case report of patient with a huge multilobulated pseudocyst that required cysto-gastric anastomosis is presented.

Drenagem endoscópica transmural de pseudocisto pancreático: resultados a longo prazo / Transmural endoscopy drainage of pancreatic pseudocyst: long-term outcome

RACIONAL: Os pseudocistos pancreáticos são complicações relativamente comuns em pacientes adultos com pancreatite. OBJETIVO: Avaliar os resultados a longo prazo da drenagem endoscópica transmural, estabelecendo seu papel no manejo do pseudocisto pancreático. MÉTODOS: Foram estudados 14 pacientes com pseudocisto de pâncreas, cuja principal queixa à apresentação foi dor no andar superior do abdome e massa abdominal palpável, submetidos a cistogastrostomia (n = 12) e cistoduodenostomia (n = 2), acompanhados clinicamente e com tomografia computadorizada de abdome por até 51 meses. A colangiopancreatografia endoscópica retrógrada era tentada em todos os casos para estudo do ducto pancreático e classificação dos cistos. RESULTADOS: A pancreatite crônica alcoólica agudizada foi responsável por 10 casos (71,5 por cento) e a biliar por 4 (28,5 por cento). As duas formas de drenagens (cistogastrostomia e cistoduodenostomia) endoscópicas foram efetivas. Não houve mudança na conduta terapêutica proposta; em dois pacientes a migração da órtese para o interior do pseudocisto, no momento da inserção, foi a principal complicação, sendo possível sua retirada no mesmo ato, com o uso da cesta de Dormia, sob o auxílio de fluoroscopia. Não houve mortalidade, nem recidiva até o momento. O tempo médio de permanência hospitalar foi de 3 dias. CONCLUSÃO: A drenagem endoscópica transmural se apresentou como terapêutica eficaz, com baixo índice de complicações, mortalidade nula e pequeno tempo de internação hospitalar.

BACKGROUND: Pancreatic pseudocysts are relatively common complications of pancreatitis in adults. OBJECTIVE: To evaluate the long-term results from transmural endoscopic drainage and thus to establish its role in managing pancreatic pseudocyst. METHODS: Fourteen patients with pancreatic pseudocyst were studied. Their main complaint was pain in the upper levels of the abdomen. They presented palpable abdominal mass and underwent cystogastrostomy (n = 12) and cystoduodenostomy (n = 2), with clinical follow-up using abdominal computed tomography for up to 51 months. Retrograde endoscopic cholangiopancreatography was attempted in all cases to study the pancreatic duct and classify the cysts. RESULTS: There were 10 cases (71.5 percent) of chronic pancreatitis that had become acute through alcohol abuse and 4 (28.5 percent) that had become acute through biliary disorders. Both types of endoscopic drainage (cystogastrostomy and cystoduodenostomy) were effective. There was no change in the therapeutic management proposed. Migration of the orthesis into the pseudocyst at the time of insertion (two cases) was the principal complication, and these could be removed during the same operation, by means of a Dormia basket, with the aid of fluoroscopy. There has so far not been any mortality or relapse. The mean hospital stay was 3 days. CONCLUSION: Transmural endoscopic drainage was an efficacious form of therapy, presenting a low complication rate and no mortality, and only requiring a short stay in hospital.

Manejo endoscópico del pseudoquiste pancreático / Endoscopic management of pancreatic pseudocyst

Los pseudoquistes pancreáticos son colecciones de fluido localizadas, rodeadas por una pared no epitelial, que habitualmente aparecen tras la rotura u obstrucción de un conducto pancreático, secundario a un episodio de pancreatitis o a un traumatismo. Los síntomas independientemente de su origen son: dolor, náusea, fiebre y pérdida de peso. Es frecuente encontrar al examen una masa palpable, generalmente epigástrica y menos frecuentemente ictericia. En relación a su tratamiento este depende tanto del tamaño del pseudoquiste, el tiempo de evolución y el estado en que se encuentra el paciente, pues no es inhabitual que pseudoquistes pequeños, en pacientes estables tengan una resolución espontánea. Sin embargo, cuando esto no ocurre está indicado el drenaje quirúrgico del pseudoquiste, que puede ir desde un drenaje externo, hasta técnicas mimamente invasivas, ya sean laparóscopicas o endoscópicas, que en los últimos años han tenido un fuerte desarrollo. En relación a esto, presentamos un caso de drenaje endoscópico interno realizado en el Hospital Base Valdivia, de un pseudoquiste pancreatico, en un paciente de 36 años secundario a pancreatitis aguda grave.

Large Adrenal Pseudocyst. Report of a Case

Authors report a case of large adrenal pseudocyst in a 53 year-old woman. A voluminous abdominal mass with malnutrition and dehydration symptoms were found. Surgical excision was difficult but complete after 6L fluid aspiration. Histologic examination showed fibrous and inflammatory cystic wall with groups of adrenal cells. No epithelial lining was present and the diagnosis of adrenal pseudocyst was made. Pathogenesis; histology; diagnosis and management were discussed

Pancreatic pseudocysts in Nigerian children

Pancreatic pseudocyst is uncommon in childhood and there is a paucity of literature on its occurrence in Nigeria. This was a retrospective study to highlight the clinical presentation and outcome of management of pancreatic pseudocyst in childhood. Twelve patients were managed in 6 years in 3 hospitals in north-central; Nigeria. There were seven girls and five boys. The median age at presentation was 5.8 years. The patients presented usually with abdominal pain; abdominal mass and fever. There was definite history of trauma in only two patients. Abdominal utrasonography suggested the diagnosis in 10 of the 11 patients examined. Non operative management with ultrasound monitoring was successful in one patient. The others had surgical internal drainage. The procedures performed were cystgastrostomy (7 patients); cystjejunostomy (3 patients) and cyst duodenostomy in one patient. The post-operative period was uneventful in all patients. There was no mortality recorded. The median duration of hospital stay was 8 days. There was no recurrence in three patients available for long term follow up. Pancreatic pseudocyst should be included in the differential diagnosis of abdominal masses in childhood. As is evidenced in this series the prognosis in childhood following prompt surgical intervention is good
