ABSTRACT
INTRODUCCIÓN: El adenocarcinoma de cuerpo y cola de páncreas corresponde a cerca de un tercio del total de cánceres pancreáticos. Evoluciona en forma silenciosa hasta alcanzar estadios avanzados, llegando a comprometer muchas veces grandes vasos como tronco celíaco y sus ramas, y la arteria mesentérica superior. La resolución quirúrgica parece ser la única alternativa en estos casos. OBJETIVO: Presentar dos casos de adenocarcinoma de cuerpo y cola de páncreas tratados en nuestro hospital con pancreatectomía corpo-caudal y resección en bloque de tronco celíaco (procedimiento de Appleby modificado). DISCUSIÓN: Este procedimiento ha demostrado aumentar la sobrevida de estos pacientes, además de generar un alivio inmediato y duradero del dolor. Sin embargo, corresponde a una intervención con una alta morbilidad, siendo la fístula pancreática y la gastropatía isquémica las complicaciones más frecuentes. La evaluación del flujo de los vasos colaterales es un paso crítico para evitar las complicaciones isquémicas. CONCLUSIONES: La pancreatectomía corpo-caudal con resección en bloque de tronco celíaco, es una alternativa factible en adenocarcinoma de cuerpo y cola de páncreas localmente avanzado. Su indicación debe ser cuidadosa debido a que corresponde a un procedimiento con alta morbilidad.
INTRODUCTION: Adenocarcinoma of the body and tail of the pancreas corresponds to about one third of all pancreatic cancers. It evolves silently to reach advanced stages, often involving large vessels such as the celiac trunk and its branches, and the superior mesenteric artery. Surgical resolution seems to be the only alternative in these cases. AIM: To present two cases of adenocarcinoma of the body and tail of the pancreas treated in our hospital with distal pancreatectomy and celiac trunk en block resection (modified Appleby procedure). DISCUSSION: This procedure has been shown to increase the survival of these patients, in addition to generating immediate and lasting pain relief. However, it corresponds to an intervention with a high morbidity, being the pancreatic fistula and the ischemic gastropathy the most frequent complications. The evaluation of the flow of the collateral vessels is a critical step to avoid ischemic complications. CONCLUSIONS: Distal pancreatectomy with en bloc resection of the celiac trunk is a feasible alternative in locally advanced adenocarcinoma of the body and tail of the pancreas. Its indication must be careful since is a procedure with high morbidity.

Common celiacomesenteric trunk, with the celiac and superior mesenteric arteries having a common origin from the aorta, is the least frequently reported anatomic variation of all abdominal vascular anomalies. Knowledge of variations concerning the celiac trunk and superior mesenteric artery are of great importance for both surgical approaches and angiographic examinations. Clinicians should keep in mind these variations to avoid complications.
O tronco único celíaco-mesentérico, com as artérias celíaca e mesentérica superior tendo uma origem comum a partir da aorta, é a variante anatômica menos reportada dentre todas as anomalias vasculares abdominais. Conhecer as variantes do tronco celíaco e da artéria mesentérica superior é de grande importância tanto para abordagens cirúrgicas quanto para exames angiográficos. É importante que os médicos tenham em mente essas variantes a fim de evitar complicações.

The prognosis of distal pancreatic cancer is even poorer than that of pancreatic head cancer because of its late symptom onset and tendency of aggressive retroperitoneal invasion at diagnosis. Since the first Appleby's operation in 1952, it has been performed in stomach cancer by several surgeons. But the survival benefit is still controversial. Appleby's operation includes total gastrectomy, splenectomy, distal pancreatectomy, celiac trunk division with ligation of common hepatic artery(CHA) and retroperitoneal lymph node dissection. In 1976, Nimura first adopted this method for distal pancreatic cancer. We report a case of modified Appleby's operation for distal pancreatic cancer. The patient was 44- year old female. Her chief complaint was epigastric pain for 2 weeks. Preoperative liver function test was within normal range and CA19-9 was elevated to 200 U/ml. Preoperative CT angiography showed 4.5x3cm sized, pancreatic mass in body and tail area invading splenic artery and celiac trunk from its left side. In operation, splenectomy and distal pancreatectomy was initially performed. After ligation of CHA, we confirmed intact proper hepatic artery(PHA) flow by doppler and then divided CHA. After confirmation of intact gastric blood flow, left gastric artery(LGA) was divided. Celiac axis(CA) was divided near its origin. Then we dissected retroperitoneal lymph nodes. There was minor pancreatic leakage controlled by conservative management. CA19-9 was normalized to 33 U/ml on the 16th postoperative day. She was discharged on the 28th postoperative day and underwent adjuvant chemotherapy and radiotherapy. There is no evidence of recurrence for 15 months of follow-up. We suggest that modified Appleby's operation should be considered for radical resection of distal pancreatic cancer which is invading CA or major CA branch but not involving PHA and superior mesenteric artery(SMA), if the CA root is resectable and PHA flow is intact from SMA after ligation of CHA.
