Fluid administration in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: neither too much nor too little

Abstract Introduction Intraoperative fluid therapy in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy plays an important role in postoperative morbidity. Studies have found an association between overload fluid therapy and increased postoperative complications, advising restrictive intraoperative fluid therapy. Our objective in this study was to compare the morbidity associated with restrictive versus non-restrictive intraoperative fluid therapy. Methods Retrospective analysis of a database collected prospectively in the Anesthesiology Service of Virgen del Rocío Hospital, from December 2016 to April 2019. One hundred and six patients who underwent complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were divided into two cohorts according to Fluid Therapy received 1. Restrictive ≤ 9 mL.kg-1.h-1 (34 patients), 2. Non-restrictive ≥ 9 mL.kg-1.h-1 (72 patients). Percentage of major complications (Clavien-Dindo grade III-IV) and length hospital stay were the main outcomes variables. Results Of the 106 enrolled patients, 68.9% were women; 46.2% had ovarian cancer, 35.84% colorectal cancer, and 7.5% peritoneal cancer. The average fluid administration rate was 11 ± 3.58 mL.kg-1.h-1. The restrictive group suffered a significantly higher percentage of Clavien-Dindo grade III-IV complications (35.29%) compared with the non-restrictive group (15.27%) (p= 0.02). The relative risk associated with restrictive therapy was 1.968 (95% confidence interval: 1.158-3.346). We also found a significant difference for hospital length of stay, 20.91 days in the restrictive group vs 16.19 days in the non-restrictive group (p= 0.038). Conclusions Intraoperative fluid therapy restriction below 9 mL.kg-1.h-1 in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy was associated with a higher percentage of major postoperative complications.

Objetivo: Descrever o padrão histopatológico e identificar a incidência de carcinomatose peritoneal no momento do diagnóstico de mulheres diagnosticadas com neoplasia de ovário. Métodos: Trata-se de um estudo transversal e descritivo, baseado na análise secundária de dados correspondentes aos prontuários de mulheres adultas com diagnóstico de neoplasia de ovário de um serviço de referência em oncologia clínica. Foram analisados 40 prontuários entre janeiro de 2007 e janeiro de 2017. Resultados: Ao estadiamento segundo o sistema da International Federation of Gynecology and Obstetrics, três mulheres (7,5%) apresentavam estadiamento clínico (EC) II, três (77,5%) estágio ECIII com carcinomatose peritoneal/invasão da pelve e seis (15%) estágio ECIV com metástases à distância, especialmente para pulmão e fígado. Em relação ao padrão histopatológico, 20 mulheres apresentaram adenocarcinoma seroso papilífero de alto grau (50%), 4 (10%) adenocarcinoma seroso papilífero de baixo grau, 3 (7,5%) adenocarcinoma endometrioide, 3 (7,5%) tumor de teca/granulosa, 3 (7,5%) carcinoma de células claras, 3 (7,5%) tumores não classificados, 2 (5%) disgerminoma e 2 (5%) com cistoadenocarcinoma mucinosos. Conclusão: É nítida a necessidade de mais estudos envolvendo essa patologia, de modo a favorecer o diagnóstico e a intervenção em estágios mais precoces e reduzir desfechos desfavoráveis. (AU)

Objective: To describe the histopathological pattern, and to identify the incidence of peritoneal carcinomatosis at the time of the diagnosis of women diagnosed with ovarian neoplasm. Methods: This is a cross-sectional and descriptive study, based on the secondary analysis of data corresponding to the medical records of adult women diagnosed with ovarian neoplasm in a reference service of clinical oncology. A total of 40 medical records were analyzed between January 2007 and January 2017. Results: At the staging (FIGO system) of the International Federation of Gynecology and Obstetrics, three women (7.5%) had clinical staging (EC) II staging, 31 (77.5%) were in the ECIII stage, with peritoneal carcinomatosis/pelvic invasion, six (15%) were in the ECIV stage, with metastases at a distance, especially to lung and liver. Regarding the histopathological pattern, twenty women had high-grade papillary serous adenocarcinoma (50%), 4 (10%) with low-grade papillary serous adenocarcinoma, 3 (7.5%) with endometrioid adenocarcinoma, 3 (7.5%) with granulosa-theca tumor, 3 (7.5%) with clear cell carcinoma, 3 (7.5%) with unclassified tumors, 2 (5%) with dysgerminoma, two (5%) with mucinous cystadenocarcinoma. Conclusions: There is a clear need for further studies involving this pathology, in order to favor diagnosis and intervention at earlier stages and to reduce unfavorable outcomes. (AU)

Mesotelioma benigno como causa de dolor abdominal inespecífico en un paciente con Enfermedad de Crohn / Benign multicystic peritoneal mesothelioma in a patient with Crohn disease

Benign multicystic peritoneal mesothelioma is an uncommon lesion arising from the peritoneal mesothelium. It is asymptomatic or presents with unspecific symptoms. Imaging techniques may reveal it, however the final diagnosis can only be made by histopathology. Surgery is the only effective treatment considering its high recurrence rate. We report a 19 years old male with Crohn’s disease. Due to persistent abdominal pain, an abdominal magnetic resonance imaging was performed, showing a complex cystic mass in the lower abdomen. The patient underwent surgery and the lesion was completely resected. The pathological study reported a benign multicystic peritoneal mesothelioma.

Linfangiomatosis mesentérica como causa de abdomen agudo en la tercera edad / Mesenteric lymphangiomathosis presenting as an acute abdomen in an older subject

We report a 71 years old male who consulted in the emergency room for abdominal pain lasting 12 hours. On physical examination there was pain on abdominal palpation and signs of peritoneal irritation. An abdominal CT scan showed a thickening of the medial and distal ileum, multiple adjacent collections and signs of peritonitis. The patient was operated, observing multiple white tumors in the mesentery and serosa of small bowel, one of these lesions, adhered to the bowel wall, had a hemorrhagic infarct. One of the lesions was punctured, obtaining a milky fluid. Biopsies were obtained and the infarcted lesion was excised. The pathological study reported a Mesenteric Multilocular Lymphangioma. The patient had an uneventful postoperative evolution.

Presentamos el caso clínico de un hombre de 71 años, sin antecedentes mórbidos, salvo apendicectomía y colecistectomía hace más de 20 años. Consulta en servicio de urgencias por dolor abdominal de 12 horas de evolución, sin otros síntomas asociados. Al examen físico destacaba dolor abdominal e irritación peritoneal a la palpación de hipocondrio izquierdo. Exámenes destacan aumento de parámetros inflamatorios, Ia tomografía computada de abdomen y pelvis revela engrosamiento de íleon medio-distal, con múltiples colecciones adyacentes y signos de peritonitis. Se realiza laparotomía exploradora, evidenciándose múltiples tumoraciones blanquecinas en mesenterio y serosa de todo el intestino delgado, una de las cuales se aprecia con infarto hemorrágico adherida a Ia pared abdominal. Punción de lesiones da salida a líquido lechoso. Se toman biopsias y se reseca lesión infartada. Paciente evoluciona favorablemente, dado de alta al tercer día. La histología reveló un Linfangioma Quístico Multilocular Mesentérico. Pese a ser una patología infrecuente, debe ser considerada dentro de los diagnósticos diferenciales de abdomen agudo, siendo extremadamente rara su presentación en Ia tercera edad.

Linfangioma mesentérico multiquístico como causa de vólvulo intestinal / Mesenteric lymphangioma causing volvulus: report of one case

Lymphangiomas are rare benign lesions, most commonly seen in children and adolescents. Their intra-abdominal presentation is uncommon. We report a 19 years old male, presenting to the emergency room with abdominal pain associated with fever, vomiting and abdominal distension. There was a history of multiple previous consultations for abdominal pain. A plain abdominal X-ray examination suggested a bowel obstruction. At surgery a volvulus and dilation of the small bowel in relation to a vascular malformation was found, excising 40 cm of jejunum with an end-to-end intestinal anastomosis. The pathology report showed a Mesenteric Multicystic Lymphangioma. Presently, the patient is in good conditions.

Los linfangiomas son lesiones benignas, de baja incidencia, más comunes en niños y adolescentes. Con muy baja frecuencia son intraabdominales y poseen presentación clínica variable, yendo desde el hallazgo clínico hasta pacientes con riesgo vital por abdomen agudo. Presentamos el caso de un paciente de 19 años, sin antecedentes mórbidos que acude a urgencias por dolor abdominal asociado a fiebre, vómitos y distensión abdominal; la radiografía simple es sugerente de obstrucción intestinal. En laparotomía exploradora se encuentra un vólvulo y dilatación del intestino delgado en relación a una malformación vascular y lesiones multilobuladas en mesenterio. Se resecan 40 cm de yeyuno y realiza anastomosis término-terminal. La histología reveló un Linfangioma Multiquístico Mesentérico. El paciente evoluciona en buenas condiciones generales y se mantiene control clínico e imagenológico seriado. Aunque infrecuente, es uno de los diagnósticos diferenciales de abdomen agudo. A pesar de su naturaleza benigna puede llegar a comprometer el pronóstico vital del paciente.

Extra genital heterologous malignant mixed mullerian tumor of primary peritoneal origin.

The case of an extragenital heterologous malignant mixed müllerian tumor (MMMT) of primary peritoneal origin occurring in a 76-year-old female is presented. A large tumor was seen between the uterus and rectosigmoid occupying the entire pelvis. The uterus, fallopian tubes and ovaries were uninvolved. The tumor was composed of carcinomatous areas showing endometrioid and serous papillary differentiation and sarcomatous areas showing cartilaginous differentiation. The extragenital primary MMMTs of the female peritoneum are thought to originate from the secondary müllerian system. This case is presented for its rarity. To the best our knowledge, this is the first case of extragenital MMMT of primary peritoneal origin in Indian literature.

Giant Mesenteric Lipoma As an Unusual Cause of Abdominal Pain: A Case Report and a Review of the Literature

We report a rare case of giant mesenteric lipoma presenting with colicky abdominal pain. A 29-yr-old woman underwent laparoscopic resection for a giant mesenteric lipoma causing compression of the ileal loop. The resected ileal segment was encased by a giant fatty tissue, and normal mucosal fold patterns of the resected ileum were effaced by the mass. Microscopically, the mass was characterized by homogenous mature adipose tissue without cellular atypia, which was compatible with the diagnosis of a mesenteric lipoma. Despite the benign nature of this tumor, total excision with or without the affected intestinal loop should be considered if intestinal symptoms such as abdominal pain are present.

Disseminated peritoneal leiomyomatosis: a case report.

Disseminated peritoneal leiomyomatosis (DPL) is an exceedingly rare condition that simulates metastatic tumour and mostly occurs in women of reproductive age group subjected to an altered hormonal milieu, usually pregnancy. Here we report a case of a pregnant 28 year female with DPL, spontaneously regressing after pregnancy.

Mesenteric fibromatosis with involvement of the gastrointestinal tract.

Primary mesenteric fibromatosis is a rare condition. The aggressive nature of these tumors and the potential for major morbidity secondary to resection makes it a challenging disease for the surgeon. We report a case of mesenteric fibromatosis with involvement of small bowel.

Laminin concentration in ascites of patients with hepatic cirrhosis and peritoneal carcinomatosis

Laminin levels in ascitic fluid have been proposed as a marker for neoplastic ascites. We compared the concentration of laminin in serum and in ascitic fluid from patients with hepatic cirrhosis and peritoneal carcinomatosis and assessed the diagnostic value of serum laminin levels in differentiating neoplastic from benign ascites. Laminin concentrations were determined by ELISA with antibodies against laminin extracted from the human placenta, in patients with ascites due to peritoneal carcinomatosis (N = 20) and hepatic cirrhosis (N = 33). Patients with infected or hemorrhagic ascites were excluded. The receiver operating characteristic curve was used to determine the sensitivity and specificity of serum laminin for the diagnosis of neoplastic ascites. When compared to the group with cirrhosis, the carcinomatosis group presented significantly higher mean laminin levels in serum (3.3 ± 0.5 vs 2.1 ± 0.4 æg/ml, mean ± SD, P < 0.05) and ascites (2.8 ± 0.5 vs 1.6 ± 0.4 æg/ml, P < 0.05). Although laminin concentration was higher in serum than in ascites, the laminin serum/ascites ratio and serum-ascites gradient did not differ between the studied groups. A significant correlation (r = 0.93, P < 0.0001) was observed between the serum and ascites laminin values. Serum laminin levels >2.25 æg/ml showed 100 percent sensitivity and 73 percent specificity for the diagnosis of neoplastic ascites. Serum concentration seems to be the main determinant of laminin levels in ascitic fluid and its values can be used as a diagnostic parameter in the study of neoplastic ascites.

Malignant fibrous histiocytoma of peritoneum presenting as intestinal obstruction.

Malignant fibrous histiocytoma (MFH) is a high-grade soft-tissue sarcoma of fibroblast-cell origin with a propensity for metastasis and recurrence. Primary MFH of the peritoneum is rare. We report a 60-year-old man with MFH of the peritoneum presenting with obstructive symptoms. Complete surgical excision of the tumor was done, and he is well six months later.

Mesenteric lipoma: an unusual cause of small intestinal volvulus.

Mesenteric lipoma as a cause of small intestinal volvulus has not been reported before. We report a middle-aged man with this entity.
