Objective:To investigate the perioperative alterations and management of coagulation function in patients of massive blood transfusion during retroperitoneal tumor (RT)resection.Methods:Fourty-seven RT patients at Peking University International Hospital from Jan 2016 to Dec 2021 undergoing resection with massive blood transfusion more than 20 U within 24 h were reviewed for coagulation function before and after surgery.Results:Intraoperative bleeding was 3 000-25 800 ml, 10 patients had blood loss ≥10 000 ml. During the operation, (25.3±9.9) U of red blood cells were transfused, (2 720±1 369) ml plasma transfused, and (2.4±3.3) U platelets were transfused in 6 patients. Fourty-five patients received intraoperative albumin of (79.5±46.5) g; All 47 patients received fibrinogen of (2.3±1.3) g; Prothrombin complex was given in 45 patients (1 205±807) U. Preoperative hemoglobin was statistically different compared to postoperatively and days 1, 3 and 5 ( W=1 790, P<0.001; W=1 672, P<0.001; W=1 704, P<0.001; W=1 486, P=0.004);As with platelets, the difference was also statistically significant compared to postoperative days 1, 3, and 5 ( W=2 153, P<0.001; W=2 092, P<0.001; W=1 732, P<0.001); Preoperative albumin was different compared to postoperative days 1 and 3 ( W=1 568, P<0.001; W=1 578, P<0.001,); Preoperative fibrinogen was different compared to postoperative day 1 ( W=1 964, P<0.001). PT and APTT were prolonged on postoperative days 1 and 3 ( W=628, P<0.001, W=804, P=0.023) ( W=661, P<0.001, W=796, P=0.02). Patient's preoperative fibrin degradation products and D-dimer were above the normal value and were higher on postoperative days 3 and 5 ( W=498, P<0.001, W=345, P<0.001). Conclusions:Coagulation disorders occur perioperatively in patients with massive transfusion while undergoing surgery for RT.The implementation of ratiional transfusion strategy and close postoperative survey and management of coagulation dysfunction help avoid the coagulation related morbidities.

Ganglioneuromas arise from neural crest sympathogonia and are rare benign neurogenic tumors. The most common affected sites are posterior mediastinum and the retroperitoneum. They rarely affect adrenal glands. Ganglioneuromas often present as solitary, painless and slow growing mass and are benign in nature. These tumors are closely related to major vessels. Hence, surgical management of retroperitoneal pathologies may require multiorgan resection in order to achieve complete surgical resection while preservation of surrounding organs especially in case of benign tumors. We present a case report of a 21 year old male with a 12×10×10 cm size right sided retroperitoneal ganglioneuroma which on computed tomography (CT) mimicked adrenal tumor crossing the midline and abutting the aorta and splaying the inferior venal cava and renal vein. Present paper is an attempt to review the various surgical options available while dealing with these benign retroperitoneal tumors which are related closely to retroperitoneal organs and major vessels.

Los tumores retroperitoneales de origen neurogénico benignos son infrecuentes; suelen ser asintomáticos y manifestarse tardíamente con síntomas imprecisos, tumor palpable o de compresión a estructuras adyacentes; cuando son funcionantes, la expresión constante es la hipertensión arterial. Debido a su rareza, ubicación y relación con grandes vasos, el abordaje laparoscópico ha sido inusual, por lo cual el empleo de esta estrategia operatoria aún no ha sido completamente aclarado. Se presenta una paciente, de 40 años, a quien en un estudio ultrasonográfico casual se le encuentra una lesión retroperitoneal, adyacente a la vena cava inferior. Se indica y describe la técnica empleada, que fue el abordaje laparoscópico transperitoneal. La duración de la intervención fue de 46 minutos, la pérdida sanguínea de 10 mL, el dolor escaso y el tiempo de internación, 48 horas. El resultado anatomopatológico confirmado por inmunohistoquímica fue de schwannoma. El control clínico y por imágenes a 14 meses es normal. Se realizan las consideraciones de esta patología tan infrecuente y se concluye que el abordaje transperitoneal laparoscópico de lesiones retroperitoneales es factible, con todas las ventajas que esta vía ofrece.
Benign neurogenic retroperitoneal tumors are rare, usually asymptomatic or present non-specific symptoms as a palpable mass or compression of the surrounding structures. Functional tumors are associated with hypertension. Due to their rarity, location and relationship with the surrounding vascular structures, the use of the laparoscopic approach to remove these tumors is unusual, and the routine use of this strategy has not been clarified yet. We report the case of a 40-year-old female patient with an ultrasound showing a retroperitoneal mass adjacent to the inferior vena cava. A transperitoneal approach was decided and the technique is described. Operative time was 46 minutes, blood loss was 10 mL, pain was minimal and hospital stay was 48 hours. The pathological examination and immunohistochemical tests revealed the presence of a schwannoma. Follow-up image tests and clinical examination at 14 months were normal. The considerations of this rare condition are made, concluding that transperitoneal laparoscopic approach for retroperitoneal masses is feasible with all the advantages provided by this method.

Objectives: Gauze remnants form gauzeomas after surgery, if infection has not occurred. We present a case of gauzeoma diagnosed after surgery.Patient: A 72-year-old man noticed a mass in his lower abdomen. He had undergone surgery for left inguinal hernia 21 years ago. A retroperitoneal mass was found on computed tomography (CT) and magnetic resonance imaging (MRI), and he was then referred to our hospital. A detailed abdominal ultrasonography, CT, and MRI revealed a cystic mass with a bulkhead-like structure near the bladder. These findings indicated the possibility of a malignant cyst; hence, an open surgery was performed to excise the mass. Macroscopically, the specimen was clearly bound, covered with a capsule, and filled with pus and had a gauze inside.Results: Based on the patient history and position of the mass, it was diagnosed as gauzeoma, which had strayed into the retroperitoneal cavity during the surgery for inguinal hernia.Conclusion: The imaging findings of gauzeoma are diverse; hence, it is often difficult to diagnose without surgery. However, gauzeoma can be lethal if the cystic mass is infected; thus, it is important to diagnose it correctly.

Objective To investigate the clinical diagnosis and treatment strategies for retroperitoneal paragangliomas and to enhance the diag?nostic and therapeutic levels of retroperitoneal paragangliomas. Methods The clinical data of 49 patients having retroperitoneal paragangliomas were retrospectively analyzed. We studied 21 males and 28 females between an age range 17 and 72 years(mean 45.6 years). Hypertension was observed in 19 patients,9 patients suffered from lumbago or abdominal pain,and an abdominal mass was noted in 2 cases. Physical examination re?vealed paragangliomas in 17 patients. The positive rate of localization was 77.5%(31/40),96.0%(47/49),and 100%(10/10)using B?ultra?sound,computed tomography,and MRI respectively. Serum catecholamines were measured in 19 patients,of which 16 cases(84.2%)showed ele?vated levels. Results In our study,49 patients underwent open surgery,5 patients showed multiple tumors,and 56 tumors were found during sur?gery. The most common tumor location was periaortic and pericaval(71.4%,40/56). There were 51 cases of surgery in 49 patients. 54 tumors of 49 cases were totally resected. The tumors measured 1.5?20.0 cm in diameter with a mean diameter 6.7 cm. 75%tumors had integral pelos,14.2%(8/56)invaded the surrounding organs and vessels,and 10.7%(6/56)required resection of adjacent organs. We followed up 43 patients between 6 and 138 months after surgery. Postsurgical recurrence was noted in 4 patients,and 2 patients developed metastases. One patient died from metas?tasis during the follow?up period. Conclusion Surgical resection might be the most effective method for treatment of retroperitoneal paraganglio?mas. Sufficient preoperative and perioperative management might be the key point of successful surgery. Lifelong follow?up is important as recur?rent tumors need resection.

Objective:Characteristics of the retroperitoneal tumor blood supply arteries were analyzed to evaluate the safety and effec-tiveness of preoperative interventional embolization for benign and malignant retroperitoneal tumors. Methods:A total of 241 cases were divided into benign retroperitoneal tumor group and malignant retroperitoneal tumor group. Each group was divided into groups A, B, and C according to the long diameter of the tumor tissue. Group A>10.0 cm, 5.0 cm0.05). Significant differences in intraoperative bleeding and intraoperative blood transfusion were found between groups A and B (P<0.05). Main arteries of the abdominal retroperitoneal tumor are the lumbar, internal iliac, and adrenal arteries. The main artery of pelvic retroperitoneal tumor is the internal iliac artery. Conclusion:Preoperative interventional embolization can effec-tively reduce the risk of bleeding during malignant retroperitoneal tumor surgery and improve the perioperative safety of patients. No significant benefit of benign retroperitoneal tumors and no increased risk of bleeding during surgery were observed. Retroperitoneal tumor preoperative embolization should focus on investigating the lumbar, internal iliac, and adrenal arteries.

Las lesiones sólidas mesenquimales del retroperitoneo son infrecuentes representando menos del 1 %. De los sarcomas retroperitoneales el 10 a 15 % corresponde a liposarcomas, los cuales representan el primer diagnóstico diferencial de lipomas benignos. La realización de inmunohistoquímica, específicamente el MDM2,dará el diagnóstico histológico certero, donde su negatividad se traduce en benignidad. El tratamiento quirúrgico de elección es la resección R-0. Caso clínico: Presentamos el caso de paciente femenino de 24 años de edad quien refiere 5 meses previos al ingreso aumento de la circunferencia abdominal y dolor a predo-minio de flanco izquierdo. Exámenes clínicos y paraclínicos indican el diagnóstico presuntivo de un tumor de aspecto graso retroperitoneal. Se realiza laparotomía exploradora con los hallazgos de tumor de aspecto graso, de superficie lisa, de gran tamaño ubicado a nivel de retroperitoneo. Se realiza resección R-0 de la lesión sin complicaciones. Tiempo operatorio: 110 minutos, sangrado estima-do: 150 cc. Tumor de aspecto graso de 11 Kg y 55 cm. Paciente es dado de alta a las 48 horas tolerando vía oral. La biopsia reporta tejido adiposo maduro sin atipias. Inmunohistoquímica reporta tumor lipomatoso, MDM2 Negativo, descartando de esta manera el diagnóstico de liposarcoma. Conclusión: Podemos concluir que los lipomas gigantes a nivel de retroperitoneo corresponden a una patología poco frecuente. Donde la resolución quirúrgica se basa en la resección R-O. La realización del MDM2 permitirá un diag-nóstico histológico confiable y por ende le brindará al cirujano la capacidad de decidir el tratamiento post-operatorio(AU)
The mesenchymal solid retroperitoneal lesions are uncommon, representing less than 1%. Liposarcomas constitute 10 to 15% of the retroperitoneal sarcomas, which represent the first differential diagnosis of benign lipomas. The immunohistochemistry, specifically the MDM2, give the accurate histological diagnosis, where their negativity translates into benignity. The treatment of choice is surgical R-0 resection. Clinical case: We report the case of 24 years old female patient who refers five months before admission increased abdominal girth and pain, predominantly at the left flank. Clinical and laboratory tests indicate presumptive diagnosis of retroperitoneal fatty tumor. Exploratory laparotomy is done with the findings of large retroperitoneal lipomatous tumor. R-0 resection of the lesion is performed without complications. Operating time: 110 minutes, estimated blood loss: 150 cc. Fatty tumor aspect of 11 kg and 55 cm. The patient's progress was satisfactory and he was discharged on the second postoperative day. Mature adipose tissue biopsy reports without atypia. Lipomatous tumor immunohistochemistry reports, MDM2 negative, discarding liposarcoma diagnosing.Conclusion:We conclude that the giant retroperitoneal lipomas corresponds a rare condition. The surgical resolution is based on R-0 resection, and the MDM2 allow a reliable histological diagnosis and thus will provide the surgeon with the capacity to decide the postoperative treatment(AU)

INTRODUCCIÓN: los tumores retroperitoneales se presentan con baja incidencia en la infancia, pero tienen muy alta letalidad. Aunque estos se clasifican en primarios y secundarios, y dependen en gran medida del tejido de origen, su forma quística o sólida, o su benignidad o malignidad en Pediatría, se presentan desde la etapa de recién nacido. OBJETIVO: determinar la incidencia de los tumores retroperitoneales en el Hospital Pediátrico Universitario Centro Habana, entre el 1º de enero de 2000 y el 31 de diciembre de 2012. MÉTODOS: se realizó un estudio descriptivo longitudinal retrospectivo de los 77 pacientes tratados en el centro con diagnóstico de tumores del retroperitoneo, entre el 1º de enero de 2000 y el 31 de diciembre de 2012. Se analizaron las variables edad, sexo, síntomas y signos, tipo de tumor y tratamiento. RESULTADOS: el 57 % era del sexo femenino, el 60 % tenía entre 0 y 5 años, el nefroblastoma se presentó en 50 %. El motivo de consulta fue dolor abdominal y fiebre (40 %), y el tumor fue palpable en el 80 %. La cirugía realizada fue resección total a todos los casos. Se constataron 39 nefroblastomas, 24 neuroblastomas y 6 carcinomas de células renales, entre otros. El neuroblastoma fue más frecuente en varones, y el nefroblastoma en hembras. En menores de 5 años fueron el nefroblastoma y el neuroblastoma. CONCLUSIONES: la ecografía abdominal detectó el tumor en todos los casos, por lo que es el examen de elección en la primera etapa de estudio. La rápida progresión de los tumores malignos en Pediatría, obliga a considerar la palpación de una masa abdominal como una urgencia pediátrica.
INTRODUCTION: the incidence of retroperitoneal tumors is low at childhood, but the fatality rate is very high. Although these tumors are classified into primary and secondary depending greatly on the tissue of origin, their cystic or solid form, benignancy or malignancy in pediatrics occurs since the neonatal phase. OBJECTIVE: to determine the incidence of retroperitoneal tumors in the university pediatric hospital of Centro Habana from January 2000 through December 2012. METHODS: a retrospective longitudinal and descriptive study of 77 patients who were treated at this center and diagnosed as retroperitoneal tumors from January 2000 through December 31st, 2012. The analysis variables were age, sex, symptoms and signs, type of tumor and treatment. RESULTS: in this group, 57 % were females, 60 % aged 0 to 5 years, and nephroblastoma was present in 50 % of cases. The reason for going to the doctor's was abdominal pain and fever (40 %) and the tumor was palpable in 80 %. Total resection was the elected surgery in all the cases. There were confirmed 39 nephroblastomas, 24 neuroblastomas and 6 renal cell carcinomas, among others. Neuroblastoma was the most frequent in boys whereas nephroblastoma was common in girls. In children aged under 5 years, nephroblastoma affected boys more and neuroblastoma was frequent in girls. CONCLUSIONS: nephroblastoma (39 cases) followed by neuroblastoma (24 cases) were the most common retroperitoneal tumors found at the university pediatric hospital of Centro Habana in the period of 2000 through 2012. Abdominal echography detected tumors in all the cases, so this is the test of choice in the first stage of the study. The rapid progression of malignant tumors in pediatrics leads to considering palpated abdominal mass as an emergency in pediatrics.

Liposarcoma, the most common type of retroperitoneal tumor, usually presents late with average weight of 15-20 kg, mostly in men. Surgery is considered to be gold standard even in giant retroperitoneal liposarcomas. We report a case of 65 year old man with a giant retroperitoneal liposarcoma and show that large tumor size is not necessarily a contraindication to surgical resection.

Periadrenal retroperitoneal tumors are frequently misdiagnosed as adrenal tumors because of its rarity and anatomical vicinity. Thus, there are only very few cases reported and little information available in the literature. Preoperative diagnoses of theses tumors are challenging. The definitive diagnosis is based on postoperative pathological findings. We report two cases of periadrenal retroperitoneal tumors that mimicked adrenal neoplasms. Final diagnoses were mature cystic teratoma and papillary renal carcinoma, respectively. Although periadrenal retroperitoneal tumors are rare, it should be considered in the differential diagnosis of adrenal incidentalomas.

OBJETIVO: presentar un caso de carcinoma suprarrenal de gran tamaño, su diagnóstico y tratamiento. DESCRIPSIÓN: se presenta un paciente del sexo masculino, de 69 años de edad, con antecedentes de diabetes mellitus tipo II que refería palparse un tumor abdominal. Al examen físico tenía un tumor palpable en la fosa lumbar y flanco izquierdos de aproximadamente 15 a 16 cm de diámetro. El tumor se corroboró en el ultrasonido, por lo que fue necesario realizar la tomografía axial computadorizada simple y contrastada para establecer el origen suprarrenal de este. Se comprobaron niveles elevados de cortisol en plasma. INTERVENSIÓN: se realizó la suprarrenalectomía más la nefrectomía izquierdas. La evolución posoperatoria resultó satisfactoria. El informe histopatológico de la pieza quirúrgica fue carcinoma suprarrenal con infiltración renal. Se indicó tratamiento de quimioterapia con mitotano con posterioridad a la cirugía. En los controles semestral y anual realizados, el paciente se encontró asintomático y con niveles de cortisol sanguíneo normales. El ultrasonido, la tomografía axial computadorizada del abdomen y la radiografía del tórax no mostraron recidiva tumoral ni metástasis. CONCLUSIONES: los carcinomas suprarrenales pueden evolucionar de forma asintomática hasta alcanzar grandes dimensiones. El tratamiento combinado, quirúrgico y con quimioterapia, mejora el pronóstico de estos pacientes.
OBJECTIVE: this is the presentation of a case of a very large suprarenal carcinoma. DESCRIPTION: a male patient aged 69 with a history of type 2 diabetes mellitus mentioning the palpation of a abdominal tumor. At physical examination we noted the presence of a palpable tumor in lumbar fossa and left flanks of approximately 15 to 16 cm diameter. Ultrasound corroborated the tumor being necessary to perform a single and contrasted computed tomography to establish its suprarenal origin. There were high levels of cortisol in plasma. INTERVENTION: a left suprarenalectomy and nephrectomy were performed. Postoperative course was satisfactory. The histopathology report of the surgical specimen was a suprarenal carcinoma with renal infiltration. Chemotherapy with mitotane was prescribed after surgery. In half-yearly and yearly controls the patient was asymptomatic and with normal blood cortisol levels. Ultrasound, computerized axial tomography of abdomen and thorax X-rays not showed tumor relapse neither metastasis. CONCLUSIONS: suprarenal carcinomas may to evolve in an asymptomatic way and to have bid dimensions. Combined treatment of surgery and chemotherapy, improves the prognosis of these patients.
