RESUMEN
OBJECTIVE: The effect of a pre-operative biliary stent on complications after pancreaticoduodenectomy (PD) remains controversial. MATERIALS AND METHOD: We conducted a meta-analysis according to the preferred reporting items for systematic reviews and meta-analyses guidelines, and PubMed, Web of Science Knowledge, and Ovid's databases were searched by the end of February 2023. 35 retrospective studies and 2 randomized controlled trials with a total of 12641 patients were included. RESULTS: The overall complication rate of the pre-operative biliary drainage (PBD) group was significantly higher than the no-PBD group (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.22-1.74; p < 0.0001), the incidence of post-operative delayed gastric emptying was increased in patients with PBD compared those with early surgery (OR 1.21, 95% CI: 1.02-1.43; p = 0.03), and there was a significant increase in post-operative wound infections in patients receiving PBD with an OR of 2.2 (95% CI: 1.76-2.76; p < 0.00001). CONCLUSIONS: PBD has no beneficial effect on post-operative outcomes. The increase in post-operative overall complications and wound infections urges the exact indications for PBD and against routine pre-operative biliary decompression, especially for patients with total bilirubin < 250 umol/L waiting for PD.
OBJETIVO: El efecto de una endoprótesis biliar pre-operatoria sobre las complicaciones después de la pancreaticoduodenectomía sigue siendo controvertido. MATERIALES Y MÉTODO: Se llevó a cabo un metaanálisis siguiendo las directrices PRISMA y se realizaron búsquedas en PubMed, Web of Science Knowledge y la base de datos de Ovid hasta finales de febrero de 2023. Se incluyeron 35 estudios retrospectivos y 2 ensayos controlados aleatorizados, con un total de 12,641 pacientes. RESULTADOS: La tasa global de complicaciones del grupo drenaje biliar pre-operatorio (PBD) fue significativamente mayor que la del grupo no-PBD (odds ratio [OR]: 1.46; intervalo de confianza del 95% [IC 95%]: 1.22-1.74; p < 0.0001), la incidencia de vaciado gástrico retardado posoperatorio fue mayor en los pacientes con PBD en comparación con los de cirugía precoz (OR: 1.21; IC95%: 1.02-1.43; p = 0.03), y hubo un aumento significativo de las infecciones posoperatorias de la herida en los pacientes que recibieron PBD (OR: 2.2; IC 95%: 1.76-2.76; p < 0.00001). CONCLUSIONES: El drenaje biliar pre-operatorio no tiene ningún efecto beneficioso sobre el resultado posoperatorio. El aumento de las complicaciones posoperatorias globales y de las infecciones de la herida urge a precisar las indicaciones de PBD y a desaconsejar la descompresión biliar pre-operatoria sistemática, en especial en pacientes con bilirrubina total inferior a 250 µmol/l en espera de pancreaticoduodenectomía.

OBJECTIVES: This study aimed to compare the intestinal and pancreatobiliary subtypes of ampullary adenocarcinoma in a large patient group due to limited data on survival and risk factors. METHODS: A retrospective analysis of the clinical and pathological findings and the survival of 184 patients with ampullary adenocarcinoma who underwent curative operation between 2007 and 2018 was performed. RESULTS: Pancreatobiliary subtype had a higher prevalence of jaundice before operation than the intestinal subtype (p < 0.05). Pancreatobiliary subtype had a larger tumor size (> 2 mm) (p < 0.01) and poorer differentiation (p < 0.05) than the intestinal subtype. Perineural invasion more frequently occurred in pancreatobiliary subtype than the intestinal subtype (p < 0.01) and pancreatobiliary subtype had a higher prevalence of positive dissected lymph nodes (p < 0.05) with an advanced disease stage (p < 0.01) than the intestinal subtype. Patients of the pancreatobiliary subtype had poorer disease-free and overall survival than patients of the intestinal subtype. No survival benefit of adjuvant chemotherapy was found in either patients of the intestinal subtype or pancreatobiliary subtype. No significant difference was found in any subtypes regarding the recurrent regions. CONCLUSIONS: Pancreatobiliary subtype exhibited a higher recurrence rate and a poorer overall survival rate with more unfavorable pathological characteristics than the intestinal subtype.
OBJETIVOS: Los datos sobre la supervivencia y los factores de riesgo del adenocarcinoma ampular son limitados debido a su rareza. Este estudio buscó comparar el subtipo intestinal y el subtipo pancreático-biliar en pacientes con adenocarcinoma ampular. MÉTODOS: Análisis retrospectivo de hallazgos clínicos y patológicos y la supervivencia de 184 pacientes con adenocarcinoma ampular tratados entre 2007 y 2018. RESULTADOS: El subtipo pancreático-biliar tuvo una mayor prevalencia de ictericia antes de la operación y un tamaño de tumor mayor, y una peor diferenciación, que el subtipo intestinal. La invasión perineural fue más frecuente en el subtipo pancreático-biliar, con una mayor prevalencia de linfonodos disecados positivos y un estadio avanzado de la enfermedad. Los pacientes del subtipo pancreático-biliar tuvieron una supervivencia libre de enfermedad y una supervivencia general peores que los pacientes del subtipo intestinal. No se encontró ningún beneficio de la quimioterapia adyuvante en pacientes del subtipo intestinal o pancreático-biliar. No hubo diferencia significativa en las regiones recurrentes. CONCLUSIÓN: El subtipo pancreático-biliar mostró una tasa de recurrencia y una tasa de supervivencia general peores, con características patológicas más desfavorables que el subtipo intestinal.

BACKGROUND: Metastatic disease in the regional lymph nodes (LNs) is a strong indicator of worse outcomes among patients after curative-intent resection of ampullary cancer (AC). This study aimed to ascertain the threshold number of examined LNs (ELNs) for AC to compare the prognosis accuracy of various nodal classification schemes relative to long-term prognosis. METHODS: Patients who underwent pancreatoduodenectomy (PD) for AC (2004-2019) were identified using the National Cancer Database. Locally weighted regression scatter plot smoothing (LOWESS) curves were used to ascertain the optimal cut point for ELNs. The accuracy of the American Joint Committee on Cancer N classification, LN ratio, and log odds transformation (LODDS) ratio to stratify patients relative to survival was examined. RESULTS: Among 8127 patients with AC, 67% were male with a median age of 67 years (IQR, 59-74). Tumors were most frequently classified as T3 (34.9%), followed by T2 (30.6%); T1 (12.9%) and T4 (17.6%) were less common. LN metastasis was identified in 4606 patients (56.7%). Among patients with nodal disease, 37.0% and 19.7% had N1 and N2 disease, respectively. The LOWESS curves identified an inflection cutoff point in the hazard of survival at 20 ELNs. The survival benefit of 20 ELNs was more pronounced among patients without LN metastasis vs patients with N1 disease (median overall survival [OS]: 54.1 months [IQR, 45.9-62.1] in ≥20 ELNs vs 39.0 months [IQR, 35.8-42.2] in <20 ELNs; P < .001) or N2 disease (median OS: 22.5 months [IQR, 18.9-26.2] in ≥20 ELNs vs 25.4 months [IQR, 23.3-27.6] in <20 ELNs; P < .001). When comparing the 4 different N classification schemes, the LODDS classification scheme yielded the highest predictive ability. CONCLUSIONS: Evaluation of a minimum of 20 LNs was needed to stratify patients with AC relative to the prognosis and to minimize stage migration. The LODDS nodal classification scheme had the highest prognostic accuracy to differentiate survival among patients after PD for AC.

Primary neuroendocrine tumors (NETs) of the bile duct are extremely rare and represent only 0.2-2% of all gastrointestinal NETs. Within the biliary system, the main bile duct is the most affected site. A 28-year-old man with a 6-month history of intermittent jaundice, pruritus, and choluria. MRCP, PET-CT and endoscopic ultrasound were performed. A well-differentiated neuroendocrine neoplasia was diagnosed. Complete resection of the main bile duct was performed with lymphadenectomy of the hepatic pedicle with Roux-en-Y hepaticojejunostomy, without complications. The patient had an adequate evolution and nowadays he's disease-free. Primary neuroendocrine tumors of the bile duct are extremely rare. They may present clinically and radiologically similar to perihilar cholangiocarcinoma, which makes preoperative diagnosis difficult. Radical resection is indicated. Usually, they are well differentiated tumors, being the Ki-67 labeling index a reliable prognostic marker.
Los tumores neuroendocrinos (TNE) primarios de la vía biliar son extremadamente raros y representan sólo el 0.2-2% de todos los TNE gastrointestinales. Dentro del sistema biliar, la vía biliar principal es el sitio más afectado. Hombre de 28 años con cuadro de 6 meses de evolución caracterizado por ictericia intermitente, prurito y coluria. Se realizó colangiopancreatoresonancia magnética nuclear, PET-TC y ultrasonido endoscópico que concluyeron neoplasia neuroendocrina bien diferenciada. Se realizó resección completa de la vía biliar principal con linfadenectomía del pedículo hepático con hepaticoyeyunoanastomosis en Y de Roux, sin complicaciones. El paciente cursó adecuada evolución y se encuentra libre de enfermedad. Los tumores neuroendocrinos primarios de la vía biliar son extremadamente raros, presentándose clínica y radiológicamente como lesiones similares al colangiocarcinoma perihiliar lo que dificulta el diagnóstico preoperatorio. Está indicado su tratamiento quirúrgico radical. Suelen ser bien diferenciados, siendo el antígeno Ki-67 un marcador pronóstico confiable.

BACKGROUND: The incidence of adenocarcinoma of the ampulla of Vater has been increasing over the past years. Nevertheless, it is still a rare disease and the prognostic factors predicting long-term survival are not sufficiently clarified. This study aims to evaluate the association between histopathological characteristics and long-term survival of patients with ampullary cancer after curative resection, as well as the efficiency of immunohistochemical expression of CK7, CK20, and CDX2 to distinguish the histopathological (intestinal or pancreaticobiliary) patterns. METHODS: Demographic, histopathological data, pTNM stage, and immunohistochemical expression patterns were collected from 65 patients with adenocarcinoma of the ampulla of Vater. Five and 10-year overall and disease-free survival rates after curative resection were determined. RESULTS: Of the 65 patients with ampullary carcinoma, 47 (72%) underwent radical resection. The 5- and 10-year overall survival rate was 46% and 37%, respectively. Our results demonstrate that the main prognostic factors were the presence and number of lymph node metastases, lymph node ratio (LNR), differentiation grade, and lymphovascular invasion. After multivariate analysis, only lymph node ratio ≥ 20% remained an independent prognostic factor of survival (HR: 2.63 95% CI: 1.05-6.61; p = 0.039). CONCLUSION: Here, we demonstrated more evidence that the lymph node metastases are associated with poor prognosis in ampullary carcinoma. Particularly, the relation between the number of metastatic lymph nodes and the number of harvested lymph node (LNR) should be considered a major prognostic factor.

BACKGROUND: Endoscopic papillectomy has been conceived as a less invasive therapeutic option for treatment of early neoplastic lesions located at the major duodenal papilla. OBJECTIVE: Evaluating patients with early ampullary lesions who underwent curative intent endoscopic papillectomy related to technical success (histopathological tumor margin assessment) and safety (adverse event rate). METHODS: A retrospective study including consecutive patients who underwent curative intent endoscopic papillectomy for demographic, histopathological and pre-/post-procedural clinical assessment. Endpoints were technical success (histopathological residual tumor assessment) and adverse events rates. RESULTS: A total of 21 medical records patients with a female predominance (13 cases, 61.9%) were included. The tumor was incidental in 8 (38%) cases. Negative residual tumor resection margin rate was 72% (15 cases); three of these cases confirmed high-grade dysplasia in the resected specimen, and six cases were invasive neoplasia. Tumoral recurrence was seen in two cases, and median follow-up time was 12 months, with a 23% loss rate (five patients). Six (28.5%) patients had adverse events, all of them early (bleeding and pancreatitis); none of them required surgical intervention and there was no mortality. CONCLUSION: Endoscopic papillectomy allowed for technical successful procedure with complete removal of ampullary neoplastic lesions in the majority of cases with acceptable adverse event rates. Recurrence rate should be carefully assessed in further studies. There was a recent increase in the number of procedures. There was also a low correlation between pre- and post-histopathological assessment regarding the presence of invasive carcinoma and adenoma with high grade dysplasia, with a predominance of superficial neoplastic adenomatous lesions.

RESUMO CONTEXTO: A papilectomia endoscópica tem sido a opção terapêutica menos invasiva no tratamento de tumores precoces que acometem a papila duodenal maior. OBJETIVO: Avaliar pacientes com tumores ampulares precoces submetidos a papilectomia endoscópica com finalidade curativa, com relação ao sucesso técnico (avaliação histopatológica da margem tumoral) e sua segurança (taxa de eventos adversos [EAs]). MÉTODOS: Foram avaliados retrospectivamente dados demográficos, exame histopatológico e evolução clínica pré e pós-procedimento de pacientes consecutivos submetidos a papilectomia endoscópica. Os desfechos avaliados foram o sucesso técnico (avaliação histopatológica de tumor residual) e taxa de EAs. RESULTADOS: Um total de 21 prontuários de pacientes com predominância feminina (13 casos, 61,9%) foi incluído no estudo. O diagnóstico tumoral foi incidental em 8 (38%) casos. A taxa de margem de ressecção negativa foi 72% (15 casos); três destas lesões confirmaram displasia de alto grau (DAG) no espécime ressecado e seis casos de neoplasia invasora. Houve recorrência tumoral em dois casos e a mediana de seguimento foi de 12 meses, com 23% de taxa de perda de seguimento (cinco casos). Seis (28,5%) pacientes apresentaram EAs, todos precoces (hemorragia e pancreatite aguda); nenhum destes necessitou de intervenção cirúrgica e não houve mortalidade. CONCLUSÃO: A papilectomia endoscópica permitiu sucesso técnico, com a completa remoção de lesões neoplásicas ampulares na maioria dos casos com taxa de EAs aceitáveis. A taxa de recorrência tumoral deve ser cuidadosamente avaliada em estudos futuros. Houve um aumento recente do número de procedimentos realizados. Também houve baixa correlação entre o diagnóstico histológico pré e pós-procedimento para a presença de adenocarcinoma invasor e adenoma com DAG, com predomínio de lesões adenomatosas superficiais.

BACKGROUND: Pancreatoduodenectomy or Whipple's operation, is the elective surgical procedure to treat different periampullary diseases. Through the years this surgery has been doing open, but in the lasts decades thanks to the improve technology and trained surgeons, today is feasible doing it laparoscopic with good results. OBJECTIVE: To present the initial experience and results in totally laparoscopic pancreatoduodenectomy in Hospital Regional ISSSTE Puebla, reporting the second number of cases in México. METHOD: Since July 2014-July 2018, 8 patients has been operated by totally laparoscopic pancreatoduodenectomy, 7 in Hospital Regional ISSSTE Puebla and 1 in a private Hospital. RESULTS: Evaluating all the patients, not one had mortality during operation, no morbidity or immediate reoperation, so the results are favourable. CONCLUSION: Laparoscopic pancreatoduodenectomy is a very complex procedure but feasible, and good results depends on various factors, like the appropriate patient selection.
ANTECEDENTES: La pancreatoduodenectomía o cirugía de Whipple es el procedimiento de elección en el tratamiento de las enfermedades periampulares. A través de los años se ha realizado de manera abierta, y actualmente, gracias a la mejora de los recursos humanos y tecnológicos, se realiza este procedimiento por mínima invasión con buenos resultados. OBJETIVO: Presentar la experiencia inicial en la pancreatoduodenectomía totalmente laparoscópica en el Hospital de Alta Especialidad del Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) de Puebla, dando a conocer la segunda serie de casos reportada en México. MÉTODO: De julio de 2014 a julio de 2018 se han realizado ocho pancreatoduodenectomías totalmente laparoscópicas, siete en el hospital de alta especialidad ISSSTE Puebla y una en un hospital privado. RESULTADOS: En todos los pacientes intervenidos los resultados son favorables, sin mortalidad transoperatoria y sin presentar complicaciones graves ni reintervención. CONCLUSIÓN: La pancreatoduodenectomía laparoscópica es un procedimiento de alta complejidad que, teniendo una adecuada selección de pacientes y un manejo multidisciplinario, se puede llevar a cabo con excelentes resultados.

Acute pancreatitis (AP) is a common adverse event (AE) of endoscopic papillectomy (EP). Prophylactic plastic pancreatic stent (PPS) placement appears to prevent AP. We evaluated factors associated with post-EP AP by a retrospective analysis of patients with tumors of the duodenal papilla who underwent EP from January 2008 to November 2016 at 2 tertiary care centers. Clinical, laboratory, endoscopic ultrasound parameters, and PPS placement were evaluated. Seventy-two patients underwent EP (37 men), with mean age of 60.3 (31-88) years. Mean main pancreatic duct (MPD) diameter was 0.44 (0.18-1.8) cm. Mean tumor size was 1.8 (0.5-9.6) cm. Tumors were staged as uT1N0, uT2N0, and uT1N1 in 87.5%, 11.1%, and 1.4%. Thirty-eight AEs occurred in 33 (45.8%) patients, with no mortality. Total bilirubin, tumor size, MPD diameter, and PPS placement had odds ratios (ORs) of 0.82, 0.14, 0.00, and 6.43 for AP. Multivariate analysis (PPS placement × MPD diameter) showed ORs of 4.62 (95%CI, 1.03-21.32; p = 0.049) and 0.000 (95%CI, 0.00-0.74; p = 0.042) for AP. In conclusion, patients with jaundice, large tumors, and dilated MPD seem less likely to have post-EP AP. PPS placement was associated with a higher risk of AP, which may question its use.

BACKGROUND: Given the lack of evidence on the best adjuvant approach, this review closely examines optimal adjuvant management for resected true ampullary cancer and its histological subtypes. MATERIALS AND METHODS: A comprehensive literature search of PubMed was performed to identify studies on resected true ampullary cancers, published between January 2010 and December 2018. Data including the use of radiation, chemotherapy or chemoradiation and the outcomes were extracted. RESULTS: A total of 116 records were identified, of which 65 screened were selected. Finally, nine studies were included. Only two of the studies reported separately the outcomes of pancreatobiliary and intestinal subtypes. Patients in the selected studies were treated with a pancreaticoduodenectomy with negative margins. Patients treated with adjuvant therapy were more likely to be pT3-4 and have positive nodes; median survival ranged from 30 to 47 months. A significant benefit for adjuvant treatment was observed in four of the studies, restricted to patients at stage IIB or higher. Likewise, patients with positive nodes may have a longer median survival with adjuvant chemoradiation compared to observation. CONCLUSIONS: The present review suggests a benefit for adjuvant treatment for patients with locally advanced tumors. Randomized trials are needed to ascertain the topic, as well as studies reporting toxicity and quality of life of resected true ampullary cancer patients.

OBJECTIVE: To analyze the accuracy of endoscopic ultrasound (EUS) in the evaluation of ampullary tumors compared to histopathology (HP) staging. METHODS: A retrospective diagnostic test study. Patients with ampullary tumors staged by EUS and postpancreatoduodenectomy HP attended during 2012-2018 at tertiary level hospital. RESULTS: 14 patients with adenocarcinoma where included. Tumor size measured by EUS showed an adequate correlation (R = 0.65; p= 0.01) with HP. The accuracy in the evaluation of duodenal wall, pancreatic, and biliary duct invasion was 78.5, 78.5 and 57.1%, respectively. By HP, there were three T1 (21.4%), two T2 (14.2%) and nine T3 (64.2%). The accuracy of T and N staging by EUS was 71.4% (kappa = 0.50) and 50% (kappa = -0.04) respectively. There were more staging errors in patients with biliary stent. CONCLUSION: EUS was useful in estimating tumor size, duodenal wall and pancreatic invasion. Limitation was found in the evaluation of biliary duct invasion, as well as overestimation of T stage and underestimation of N stage. It is necessary an increased effort in ultrasonography training. We suggest EUS testing before biliary stenting.
OBJETIVO: Comparar el ultrasonido endoscópico (USE) en la valoración de los tumores ampulares primarios (TAp) con referencia al estudio histopatológico (HP). MÉTODO: Estudio retrospectivo prolectivo de pruebas diagnósticas en pacientes con TAp estadificados por USE y pancreatoduodenectomía con estudio HP, atendidos de 2012 a 2018 en un hospital de tercer nivel de atención. RESULTADOS: Fueron incluidos14 pacientes con adenocarcinoma. El tamaño del tumor medido por USE mostró una adecuada correlación (R = 0.65; p = 0.01) con el HP. La exactitud en la determinación de la invasión a la pared duodenal, el páncreas y el conducto biliar fue del 78.5, el 78.5 y el 57.1%, respectivamente. Por HP hubo tres T1 (21.4%), dos T2 (14.2%) y nueve T3 (64.2%). La exactitud del estadiaje T y N por USE fue del 71.4% (kappa = 0.50) y del 50% (kappa = −0.04), respectivamente. Los errores en la estadificación fueron más frecuentes en los pacientes con prótesis biliar. CONCLUSIÓN: El USE mostró utilidad en la determinación del tamaño tumoral y de la invasión al duodeno y al páncreas, y más limitada en la determinación de la invasión al conducto biliar por presencia de prótesis. Se observa una sobreestimación del estadiaje T y una subestimación del N. Es necesario mayor capacitación y sugerimos realizarse antes de colocar una prótesis biliar.

BACKGROUND: Periampullary neoplasms account for over 30,000 cancer-related deaths per year in the United States. Pancreaticoduodenectomy (PD) is considered the surgical standard and is the only curative treatment option for these pathologies. OBJECTIVE: The objective of this study was to report the prognostic factors in survival and surgical complications in PD. MATERIALS AND METHODS: A total of 178 cases are reported, several variables were reviewed and the same surgical technique was used by the same surgeon. RESULTS: A total of 151 PD were reviewed. The most common initial symptoms were jaundice, 111 (73%), abdominal pain, 20 (13%), and oral intolerance, 10 (6%). Poor prognostic factors for survival were the presence of a previous pathology, days of hospitalization, positive margins, and weight loss. DISCUSSION: With the experience gained, a decrease in surgical time, intraoperative bleeding, and transfusions performed was achieved. Our complication rate remained at 20%, lower than that reported in literature. CONCLUSION: PD is the only option of cure for patients with pancreatic and periampullary tumors. This procedure has been linked to high morbidity and mortality even in high-volume centers. A pancreatic fistula is the most feared complication; therefore, multiple pancreatojejunostomy techniques have been described in literature. It is important to continue reporting these cases to reach a consensus on this technique.
ANTECEDENTES: Las neoplasias periampulares suponen más de 30.000 muertes relacionadas con el cáncer por año en los EE.UU. La pancreaticoduodenectomía (PD) se considera el estándar quirúrgico y es la única opción de tratamiento curativo para esta enfermedad. OBJETIVO: Reportar los factores de pronóstico en la supervivencia y las complicaciones quirúrgicas de la PD. . MÉTODO: Se reportaron 178 casos; se revisaron varias variables y se utilizó la misma técnica quirúrgica por el mismo cirujano. RESULTADOS: Se revisaron 151 DP. Los síntomas iniciales más comunes fueron ictericia (111; 73%), dolor abdominal (20; 13%) e intolerancia oral (10; 6%). Los factores de pronóstico para la supervivencia fueron la presencia de patología previa, los días de hospitalización, los márgenes positivos y la pérdida de peso. DISCUSIÓN: Con la experiencia adquirida, se logró una disminución del tiempo quirúrgico, del sangrado intraoperatorio y de las transfusiones realizadas. Nuestra tasa de complicaciones se mantuvo en un 20%, inferior a la reportada en la literatura. CONCLUSIÓN: La PD es la única opción de curación para los pacientes con tumores pancreáticos y periampulares. Este procedimiento se ha relacionado con una alta morbilidad y mortalidad incluso en centros de alto volumen. La fístula pancreática es la complicación más temida, por lo que se han descrito numerosas técnicas de pancreatoyeyunostomía. Es importante seguir informando de estos casos para llegar a un consenso sobre esta técnica.

INTRODUCTION: Pancreatic tumors and periampullary tumors have a similar clinical presentation; pancreatoduodenectomy represents the only possibility of cure or of increasing survival; with an average mortality of 5-10% and a morbidity of 20-40%. OBJECTIVE: To determine the morbidity and mortality secondary to the pancreatoduodenectomy intervention in patients with pancreatic cancer or periampullary tumors in the Oncology Hospital of Centro Médico Nacional Siglo XXI (Mexico City) from 2008 to 2013. METHOD: Historical, observational and descriptive cohort carried out in the department of sarcomas and tumors of the upper digestive tube of the Oncology Hospital of Centro Médico Nacional Siglo XXI, postoperative pancreatoduodenectomy from 2008 to 2013. RESULTS: We included 71 patients who underwent pancreatoduodenectomy, 47 (66.2%) were female and 24 (33.8%) were male. The average age was 60.3 years. The most common histology was cancer of the Vater's ampulla (66.2%). The resections were R0 in 95.8% of the cases. Mortality was 4.22% and morbidity was 69%. The most frequent complication was pancreatic fistula (23.9%). In the statistical analysis, perioperative transfusion was associated with surgical complications (p < 0.007). CONCLUSIONS: The morbidity of pancreatoduodenectomy is greater than that reported in the literature, however, it does not influence mortality that is similar to that reported in other centers. The number of lymph nodes resected; as well as the percentage of negative margins are those accepted worldwide; It is concluded that this is derived from the experience of the center where these procedures are performed. No factor with statistical significance was found, only the transfusion that increased the complications.
INTRODUCCIÓN: Los tumores de páncreas y los tumores periampulares tienen una presentación clínica similar. La pancreatoduodenectomía representa la única posibilidad de curación o de aumentar la sobrevida, con una mortalidad promedio del 5-10% y una morbilidad del 20-40%. OBJETIVO: Determinar la morbilidad y la mortalidad secundarias a la intervención de pancreatoduodenectomía en pacientes con cáncer de páncreas o tumores periampulares en el Hospital de Oncología del Centro Médico Nacional SXXI de 2008 a 2013. MÉTODO: Cohorte histórica, observacional y descriptiva, realizada en el departamento de sarcomas y tumores de tubo digestivo alto del Hospital de Oncología del Centro Médico Nacional Siglo XXI, operados de pancreatoduodenectomía entre 2008 y 2013. RESULTADOS: Se incluyeron 71 pacientes que se sometieron a pancreatoduodenectomía; 47 (66.2%) eran de sexo femenino y 24 (33.8%) de sexo masculino. La edad promedio fue de 60.3 años. La histología más común fue cáncer de ámpula de Vater (66.2%). Las resecciones fueron R0 en el 95.8% de los casos. La mortalidad fue del 4.22% y la morbilidad fue del 69%. La complicación más frecuente fue la fístula pancreática (23.9%). En el análisis estadístico, la transfusión perioperatoria se asoció a complicaciones quirúrgicas (p < 0.007). CONCLUSIONES: La morbilidad de la pancreatoduodenectomía es mayor que lo reportado en la literatura; sin embargo, no influye en la mortalidad, que es similar a lo reportado en otros centros. El número de ganglios resecados, así como el porcentaje de márgenes negativos, son los aceptados internacionalmente. Se concluye que esto se deriva de la experiencia del centro donde se realizan estos procedimientos. No se encontró ningún factor con relevancia estadística, excepto la transfusión, que incrementaba las complicaciones.

To report the first case of Whipple surgery performed at the Regional Hospital of Tumbes for the treatment of ampullary adenocarcinoma with successful results. A case report of a patient with diagnosis of ampullary adenocarcinoma, in whom was performed the first Whipple surgery at the Regional Hospital of Tumbes, in October, 2014. The patient diagnosed with an obstructive jaundice syndrome due to ampullary adenocarcinoma underwent Whipple surgery. She performed the postoperative period with gradual improvement, she did not present with respiratory pathology, she not have fever, the patient tolerated the oral route, the jaundice decreased and she was discharged after 13 days. She presented low-output pancreatic fistula (30 cc/day), which remitted at 3 weeks. The patient presented evident clinical improvement and satisfactory surgical results to date. Whipple surgery is the surgical technique of choice in the treatment of the ampullary adenocarcinoma and it is feasible to perform, in cases that is indicated, in bounderies hospitals if you have the trained personnel and necessary logistics.

INTRODUCTION: Periampular neoplasms represent 5% of all cancers of the gastrointestinal tract with peak incidence in the 7th decade of life. The most common clinical picture is jaundice, weight loss and abdominal pain. Considering that cholestasis is related to postoperative complications, preoperative biliary drainage was developed to improve the postoperative morbidity and mortality of icteric patients with periampular neoplasias, whether resectable or not. OBJECTIVE: To describe the outcome of patients with periampullary tumors undergoing preoperative biliary drainage with pancreatoduodenectomy. METHOD: The search was performed in the Medline/PubMed and Virtual Health Library databases by means of the combination of descriptors of the Medical Subject Headings. Inclusion criteria were clinical trials, cohorts, studies that analyze the morbidity and mortality of preoperative biliary drainage in Portuguese, English and Spanish. Exclusion criteria were studies published more than 10 years ago, experimental studies, systematic reviews and articles with WebQualis C or smaller journal in the area of ââMedicine I or Medicine III. Of the 196 references found, 46 were obtained for reading with quality assessed through the Checklist Strengthening the Reporting of Observational Studies in Epidemiology. Eight studies were selected for review. RESULTS: A total of 1116 patients with a sample ranging from 48 to 280 patients and a mean age of 48 to 69 years were obtained. Of the eight studies, four observed a higher rate of bleeding in drained patients; three a higher rate of positive bile culture in the intervention group; site and cavitary infection, and biliopancreatic leaks were more common in the drainage group in two studies each. The death outcome and rate of reoperation were observed in larger numbers in the control group in one study each. CONCLUSION: Preoperative intervention leads to a higher rate of infectious complications and bleeding.

Se presenta el primer caso de cirugía de Whipple realizada en el Hospital Regional de Tumbes para tratamiento de ampuloma con resultado exitoso. Reporte de caso de una paciente con diagnóstico de ampuloma en la que se realizó la primera cirugía de Whipple efectuada en el Hospital Regional de Tumbes en octubre del año 2014. La paciente con diagnóstico de síndrome ictérico obstructivo por ampuloma fue sometida a cirugía de Whipple, cursó el post operatorio con mejoría paulatina, no presentó patología respiratoria, ni cursó con fiebre, la paciente toleró la vía oral, la ictericia disminuyó y fue dada de alta hospitalaria a los 13 días. Cursó con fístula pancreática de gasto bajo (30 cc/día) la cual remitió a las 3 semanas. La paciente presentó mejoría clínica evidente y con resultados quirúrgicos satisfactorios hasta la fecha. La cirugía de Whipple es la técnica quirúrgica de elección en el tratamiento del ampuloma y es factible de realizarse, en casos que lo ameriten, en hospitales de frontera si se cuenta con el personal capacitado y la logística necesaria.

INTRODUCTION: This study set to examine relative survival of patients with periampullary cancers undergoing pancreaticoduodenectomy (PD). METHODS: Using the Surveillance, End Results and Epidemiology (SEER) database, this study identified 9877 patients with non-metastatic pancreatic adenocarcinoma who underwent PD between 2004 and 2013. RESULTS: Ampullary carcinomas have the best survival among periampullary malignancies. Lymph node ratio is a significant prognostic factor, even when stratified by tumour types. Patients receiving adjuvant radiotherapy following PD have superior survival than patients without radiotherapy (median 25 vs 20 months, p < 0.001), particularly ductal adenocarcinoma (HR: 0.74, CI95% 0.69-0.78; p < 0.001), cholangiocarcinoma (HR: 0.75, CI95% 0.59-0.97; p = 0.027), and ampullary carcinoma (HR: 0.79, CI95% 0.64-0.98; p = 0.029) with greatest survival benefit at 1-year postresection. CONCLUSION: Future studies aiming to further define genetic signatures of individual periampullary cancers would allow a personalised therapeutic approach in improving survival.
