Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID).

BACKGROUND AND OBJECTIVES: Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease-free survival. METHODS: Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. RESULTS: The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). CONCLUSION: Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection.

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID).

BACKGROUND: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. METHODS: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. RESULTS: The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). CONCLUSIONS: Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival.

Estudio multicéntrico sobre adenomas hepáticos / Multicentre study on hepatic adenomas

INTRODUCCIÓN: El adenoma hepático (AH) es un tumor benigno que puede presentar graves complicaciones por lo que, clásicamente, todos eran resecados. Actualmente se ha demostrado que los menores de 3 cm, y si no expresan Beta -catenina, solo se complican excepcionalmente, lo que ha cambiado la estrategia terapéutica. MATERIAL Y MÉTODOS: Estudio retrospectivo en 14 unidades HPB. Criterio de inclusión: pacientes con AH resecado y confirmado histológicamente. Periodo de estudio: 1995-2011. RESULTADOS: Fueron intervenidos 81 pacientes. Edad: 39,5 años (rango: 14-75). Sexo: mujeres (75%). Consumo de estrógenos en mujeres: 33%. Tamaño: 8,8 cm (rango: 1-20 cm). Solo 6 AH (7,4%) eran menores de 3 cm. La mediana de AH fue 1 (rango: 1-12). Nueve pacientes presentaban adenomatosis (> 10 AH). El 51% de los pacientes presentaban síntomas; el más frecuente (77%) era dolor abdominal. Ocho pacientes (10%) comenzaron con abdomen agudo por rotura o hemorragia. El 67% de los diagnósticos preoperatorios fueron correctos. La cirugía fue programada en el 90% de los pacientes. Las técnicas fueron: hepatectomías mayores (22%), menores (77%) y un trasplante hepático. Un 20% fueron realizadas por laparoscopia. La morbilidad fue 28%. No hubo mortalidad. Tres pacientes presentaron malignización (3,7%). El seguimiento fue 43 meses (rango: 1-192). Se detectaron 2 recidivas que fueron resecadas. DISCUSIÓN: Los pacientes con AH resecados son habitualmente mujeres con lesiones grandes, con un consumo de estrógenos inferior al esperado. Su diagnóstico preoperatorio correcto es aceptable (70%). La tasa de hepatectomías mayores es 25% y la de laparoscopia, 20%. Hemos obtenido una baja morbilidad y nula mortalidad

INTRODUCTION: Hepatic adenomas (HA) are benign tumours which can present serious complications, and as such, in the past all were resected. It has now been shown that those smaller than 3 cm not expressing Beta-catenin only result in complications in exceptional cases and therefore the therapeutic strategy has been changed. MATERIAL AND METHOD: Retrospective study in 14 HPB units. Inclusion criteria: patients with resected and histologically confirmed HA. Study period: 1995-2011. RESULTS: 81 patients underwent surgery. Age: 39.5 years (range: 14-75). Sex: female (75%). Consumption of oestrogen in women: 33%. Size: 8.8 cm (range, 1-20 cm). Only 6 HA (7.4%) were smaller than 3 cm. The HA median was 1 (range: 1-12). Nine patients had adenomatosis (> 10HA). A total of 51% of patients displayed symptoms, the most frequent (77%) being abdominal pain. Eight patients (10%) began with acute abdomen due to rupture and/or haemorrhage. A total of 67% of the preoperative diagnoses were correct. Surgery was scheduled for 90% of patients. The techniques employed were: major hepatectomy (22%), minor hepatectomy (77%) and one liver transplantation. A total of 20% were performed laparoscopically. The morbidity rate was 28%. There were no cases of mortality. Three patients had malignisation (3.7%). The follow-up period was 43 months (range 1-192). Two recurrences were detected and resected. DISCUSSION: Patients with resected HA are normally women with large lesions and oestrogen consumption was lower than expected. Its correct preoperative diagnosis is acceptable (70%). The major hepatectomy rate is 25% and the laparoscopy rate is 20%. There was a low morbidity rate and no mortality

The European experience with vascular injuries.

The rich and diverse heritage of the management of vascular injuries in the 45 independent European countries prevents the authors from revealing a uniform picture of the European experience, but some trends are clearly emerging. In countries with a low incidence of penetrating trauma and increasing use of interventional vascular procedures, the proportion of iatrogenic vascular trauma exceeds 40% of all vascular injuries, whereas on other parts of the continent, armed conflicts are still a major cause of vascular trauma. National vascular registries, mostly in the Scandinavian countries, produce useful, nationwide data about vascular trauma and its management but suffer still from inadequate data collection. Despite a relatively low incidence of vascular trauma in most European countries, the results are satisfactory, probably in most cases because of active and early management by surgeons on call, whether with vascular training or not, treating all kinds of vascular surgical emergencies. In some countries, attempts at developing a trauma and emergency surgical specialty, including expertise in the management of vascular injuries, are on their way.
