Lesión quirúrgica de vía biliar compleja. Manejo conservador / Complex bile duct injury. Conservative management

RESUMEN La colecistectomía laparoscópica es el tratamiento de elección para la litiasis vesicular sintomática. Aunque la tasa de complicaciones es baja, las lesiones de la vía biliar representan un grave problema. La asociación con una lesión vascular (lesión compleja) genera un impacto adicional, disminuyendo la calidad de vida y la sobrevida a largo plazo. Presentamos el caso de una paciente con lesión compleja por compromiso vascular del pedículo hepático derecho que desarrolló una atrofia del parénquima correspondiente. Ante la ausencia de complicaciones sépticas, el tratamiento no operatorio pudo realizarse en forma exitosa.

ABSTRACT Laparoscopic cholecystectomy is considered the standard of care for symptomatic cholelithiasis. Although the rate of complications is low, bile duct injuries represent a serious problem. The association with vascular injury (complex injury) poses an additional impact by reducing the quality of life and long-term survival. We report the case of a female patient with complex injury due to vascular involvement of the right hepatic pedicle who developed right liver atrophy. Non-operative management was successful due to the absence of septic complications.

Abdominal puncture drainage alleviates severe acute pancreatitis in rats by activating Nrf-2/HO-1 pathway and promoting autophagy / 南方医科大学学报

OBJECTIVE@#To assess the effect of early abdominal puncture drainage (APD) on autophagy and Nrf-2/HO-1 pathway in rats with severe acute pancreatitis (SAP) and explore the possibile mechanism.@*METHODS@#Thirty-two male SD rats were randomly divided into sham-operated (SO) group, SAP group with retrograde injection of 4% sodium taurocholate, APD group with insertion of a drainage tube into the lower right abdomen after SAP induction, and APD + ZnPP group with intraperitoneal injection of 30 mg/kg ZnPP 12 h before APD modeling. Blood samples were collected from the rats 12 h after modeling for analysis of amylase and lipase levels and serum inflammatory factors. The pathological changes of the pancreatic tissue were observed with HE staining. Oxidative stress in the pancreatic tissue was detected with colorimetry, and sub-organelle structure and autophagy in pancreatic acinar cells were observed by transmission electron microscopy. The expressions of autophagy-related proteins and Nrf-2/HO-1 pathway were detected using RT-PCR and Western blotting.@*RESULTS@#Compared with those in SAP group, the rats with APD treatment showed significantly alleviated pathologies in the pancreas, reduced serum levels of lipase, amylase and inflammatory factors, lowered levels of oxidative stress, and activated expressions of Nrf-2/HO-1 pathway in the pancreas. The ameliorating effect of ADP was significantly inhibited by ZnPP treatment before modeling. APD obviously reversed mitochondrial and endoplasmic reticulum damages and p62 accumulation induced by SAP.@*CONCLUSION@#APD treatment can suppress oxidative stress and repair impaired autophagy in rats with SAP by activating the Nrf-2/HO-1 pathway, thereby reducing the severity of SAP.

Procedimiento de Whipple: experiencia de un centro en fase de crecimiento en cirugía hepato-bilio-pancreática / Whipple procedure: hepatic-bilio-pancreatic single center experience

Pancreatitis aguda posduodenopancreatectomía cefálica con complicaciones locales / Acute pancreatitis with local complications after cephalic pancreaticoduodenectomy

RESUMEN Antecedentes: la pancreatitis aguda posduodenopancreatectomía cefálica inmediata es una complica ción cuya frecuencia puede llegar al 55% y condiciona la aparición de fístula pancreática. Objetivo: describir el manejo de 3 pacientes que presentaron pancreatitis aguda posduodenopancrea tectomía con complicaciones locales y realizar una revisión de la literatura. Material y métodos: se revisó una base de datos prospectiva de resecciones pancreáticas. Se identifi caron los pacientes con diagnóstico de pancreatitis aguda con lesiones locales posterior a la realización de duodenopancreatectomía. Se definió fístula pancreática de acuerdo con la clasificación del ISGPF y pancreatitis como la elevación de la amilasa o lipasa tres veces por encima del máximo valor sérico normal en asociación con dolor abdominal o confirmación radiológica. Resultados: entre 2008 y 2019 los autores realizaron 260 duodenopancreatectomías. Tres pacientes presentaron pancreatitis posoperatoria con complicaciones locales. Conclusiones: la pancreatitis aguda posoperatoria es una complicación de una frecuencia elevada. La mayoría de ellas se resuelven en forma espontánea. Pocos pacientes presentan complicaciones locales que pueden requerir tratamiento percutáneo o quirúrgico, predisponiendo al desarrollo de fístulas a veces de difícil manejo. No hay forma de prevenir la aparición de la fístula pancreática. El tratamiento de las complicaciones locales se realizará de acuerdo con su aparición y repercusión, pudiendo requerir desde la colocación de un drenaje percutáneo hasta la pancreatectomía total.

ABSTRACT Background: The incidence of acute pancreatitis immediately after cephalic pancreaticoduodenec tomy is up to 55% and is associated with the development of pancreatic fistula. Objective: The aim of this study is to report three cases of acute pancreatitis after pancreaticoduode nectomy with local complications with a review of the literature. Material and methods: The information about pancreatic resections was retrieved from a prospective database. Patients with diagnosis acute pancreatitis with local lesions immediately after pancreatico duodenectomy were identified. Pancreatic fistula was defined according to the International Study Group on Pancreatic Fistula (ISGPF) Definition and pancreatitis was defined as serum amylase or lipase >3x upper limit of normal associated with abdominal pain or imaging criteria. Results: A total of 260 pancreaticoduodenectomies were performed between 2008 and 2019. Three patients developed postoperative acute pancreatitis with local complications. Conclusions: Postoperative acute pancreatitis is a common complication that solves spontaneously in most cases. Few patients present local complications that may require percutaneous or surgical treatment, which may predispose to the development of fistulas that are sometimes difficult to mana ge. There is no way to prevent pancreatic fistulas. Local complications will be treated according to their occurrence and impact, and may require a variety of procedures, ranging from percutaneous drainage to total pancreatectomy.

Pancreatitis aguda por hipercalcemia en el embarazo: caso clínico / Acute pancreatitis due to hypercalcemia during pregnancy: report of one case

Acute pancreatitis during pregnancy is uncommon and usually associated with gallstones. However other etiologies must be considered. We report a 24 years old woman with a 32 weeks pregnancy consulting for abdominal pain, nausea and vomiting. She had elevated lipase and amylase levels, a corrected serum calcium of 13.1 mg/dl and a serum phosphate of 1.6 mg/dl. A magnetic resonance colangiopancreatography showed an enlarged pancreas with inflammatory changes and a normal Wirsung duct. A parathyroid nodule was found on cervical ultrasonography. The patient was treated initially with cinacalcet with partial response. A parathyroidectomy was performed at 39 weeks of pregnancy with a good maternal and fetal evolution.

Páncreas divisum y pancreatitis: su importancia en la práctica cotidiana / Pancreas divisum and pancreatitis: its importance in everyday practice

Pancreas divisum (PD) is the most common congenital anatomical variant of the pancreas. Its etiological implication in recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) has been recurrently questioned. Normal anatomy and variants: 80-90% of the population has normal anatomy, with excretion of exocrine pancreatic secretion to the duodenum by the major papilla. Three anatomical variants of PD have been described: classic PD with visible ventral duct, but total absence of fusion; PD with absence of ventral duct; and incomplete PD, with a rudimentary connection between the ventral and dorsal ducts. Clinical implication: This anatomical variant is symptomatic in less than 5% of the carriers, being associated to higher prevalence in patients with RAP However, the relationship between PD and RAP is considered probable, only in cases of association with mutation of the CFTR gene. Obstructive CP can develop in the segment drained by the dorsal duct. Diagnosis: Magnetic resonance cholangiopancreatography (MRCP) is the most sensitive diagnostic method. Other non-invasive diagnostic methods are endosonography and computed tomography (CT), the latter with lower performance. Treatment: The current trend in acute pancreatitis (AP) where PD is assumed as an etiological factor, is endoscopic resolution, with papillotomy with or without a pancreatic stent.

El páncreas divisum (PD) es la variante anatómica congénita más frecuente del páncreas. Su implicancia etiológica en pancreatitis aguda recurrente (PAR) y pancreatitis crónica (PC) ha sido frecuentemente cuestionada. Anatomía normal y variantes: 80-90% de la población presenta anatomía normal, con salida de secreción pancreática exocrina al duodeno por la papila mayor. Se han descrito 3 variantes anatómicas: PD clásico con conducto ventral visible, pero ausencia total de fusión; PD con ausencia de conducto ventral; y PD incompleto, con conexión rudimentaria entre los conductos ventral y dorsal. Implicancia clínica: Esta variante anatómica da síntomas en menos de 5% de los portadores, asociándose a mayor prevalencia en pacientes con PAR. Sin embargo, se considera probable la relación entre PD y PAR, solo en casos de asociación con mutación del gen CFTR. Pancreatitis crónica (PC) obstructiva se puede desarrollar en el segmento drenado por el conducto dorsal. Diagnóstico: La colangiopancreatografía por resonancia magnética (CPRM) es el método diagnóstico más sensible. Otros métodos diagnósticos no invasivos son la endosonografía y tomografía computada (TC), este último de menor rendimiento. Tratamiento: La tendencia actual en PA donde se asume PD como factor etiológico, es la resolución endoscópica, con papilotomía con o sin stent.

Malformación arteriovenosa pancreática como causa de pancreatitis aguda tratada por vía endovascular / Pancreatic arteriovenous malformation as cause of acute pancreatitis treated by endovascular access

La malformación arterio-venosa (MAV) en el páncreas es una anomalía anatómica poco frecuente que puede ser causa de pancreatitis aguda. Presentamos el caso de un paciente de 46 años cuyo diagnóstico se sospechó por los hallazgos de la tomografía computarizada con contraste endovenoso y por resonancia magnética y se confirmó mediante una arteriografía del tronco celíaco y de la arteria mesentérica superior. El tratamiento recibido fue por vía endovascular, aunque la otra opción válida para el tratamiento de esta enfermedad es la resección quirúrgica. El objetivo de esta comunicación es presentar un caso de pancreatitis aguda por MAV tratada por vía endovascular.

Arteriovenous malformation in the pancreas is a rare anatomic abnormality that may produce acute pancreatitis. The diagnosis was suspected by computed tomography with intravenous contrast and by magnetic resonance imaging and it was confirmed by arteriography of the celiac trunk and superior mesenteric artery. The treatment received was endovascular, although the other valid option for the treatment of this disease is the surgical resection. The objective of this communication is to present a case of acute pancreatitis due to arteriovenous malformation treated by endovascular approach.

Acute Biliary Pancreatitis: A Case Report.

Acute biliary pancreatitis (ABP) a condition caused by gallstones; can be a life-threatening condition if not treated early (mortality ~2-7%). Complications and symptoms of ABP can be ranging from mild (nausea, vomiting, and fever) to severe (necrosis, infections, hemorrhage, abscesses, renal failure, and adult respiratory distress syndrome). Th is paper presents a specifi c case of a middle-aged male diagnosed with ABP to illustrate the disease in a clinical setting, mainly looking at its presentation, diagnosis and focusing more on treatment and management. Clinical examinations and radiological investigations are crucial to recognize the diagnosis and foresee the prognosis of this condition. Th e medications that are administered to patients suff ering from this condition include analgesics (like morphine), intravenous fl uids, and antibiotics (e.g. ciprofl oxacin). Th e limitations and lack of knowledge described above are immense concerns. It is highly encouraged that future research opportunities will compensate for the present gap in knowledge, contributing to current literature, as well as having practical implications for treatment and management of ABP.

Manejo endoscópico de las complicaciones de la pancreatitis / Endoscopic management of the complications of pancreatitis

Tanto la pancreatitis aguda como crónica causan diferentes complicaciones que antes del advenimiento de la terapéutica endoscópica tenían que ser tratadas con cirugía convencional. El avance de la endoscopía intervencionista nos ha permitido acceder al páncreas y tratar estas complicaciones efectivamente y con menor morbilidad para nuestros pacientes. Aproximadamente el 90% de las pancreatitis aguda son edematosas, tienen una resolución clínica temprana y sin complicaciones. Los pacientes que son admitidos con pancreatitis necrotizante están predispuestos a tener diferentes tipos de complicaciones tanto locales como sistémicas particularmente si hay falla orgánica. Por otro lado la pancreatitis crónica es un proceso inflamatorio crónico del páncreas en donde se ha establecido la fibrosis de la glándula con posible disfunción exocrina y/o endocrina. El objetivo principal de la terapéutica endoscópica en la pancreatitis crónica es aliviar la obstrucción y disminuir la presión del conducto pancreático con la intención de aliviar el dolor abdominal. En esta revisión vamos a hablar acerca de las indicaciones y técnica endoscópica para tratar las diferentes complicaciones de la pancreatitis como, drenaje de pseudoquistes, necrosectomía pancreática, manejo del síndrome de conducto desconectado y terapia endoscópica en pancreatitis crónica.

Acute and chronic pancreatitis may lead to complications that prior the recent advancement of therapeutic endoscopy had to be treated with conventional surgery. The current techniques in interventional endoscopy allow us to access the pancreas and treat some of the complications in a minimally invasive way leading to less morbidity in our patients. Approximately 90% of acute pancreatitis episodes are edematous with early resolution of clinical symptoms and rarely leading to major complications. Patients with necrotizing pancreatitis are susceptible to local and systemic complications particularly in the setting of organ failure. On the other hand chronic pancreatitis is as a chronic inflammatory process that leads to fibrosis of the gland and in occasions to exocrine and/or endocrine insufficiency. The main objective of therapeutic endoscopy in chronic pancreatitis is to relief the obstruction and decreases the pressure in the pancreatic duct with the intention to alleviate abdominal pain. In this review we will address the indications and endoscopic techniques to treat the different complications of pancreatitis such as pseudo cyst drainage, walled off necrosis debridement, disconnected duct syndrome and different options for endoscopic therapy in chronic pancreatitis.

Groove pancreatitis vs groove pancreatic adenocarcinoma. Report of two cases and review of the literature / Groove pancreatitis vs groove pancreatic adenocarcinoma. Report of two cases and review of the literature.

Groove pancreatitis (GP) is a rare form of segmental chronic pancreatitis affecting the groove area (anatomic space between the head of the pancreas, the duodenum and the common bile duct). Its clinical and radiological presentation may be similar to groove pancreatic adenocarcinoma (GPA). Nevertheless, treatment and prognosis are totally different. We report two cases of both GP and GPA and review the relevant aspects that may help to clarify the differential diagnosis between these two rare entities. The first patient is a 57-year-old man with a history of chronic alcohol consumption who presented with persistent abdominal pain. The CT-scan findings suggested GP. Due to the persistence of symptoms despite medical treatment, a pancreaticoduodenectomy was performed. Pathologic evaluation confirmed the diagnosis of GP. The second patient is a 72-year-old male who presented with cholestasis and weight loss. The tumor marker CA 19-9 was increased The CT-scan findings were consistent with duodenal dystrophy. In order to rule out malignancy a pancreaticoduodenectomy was performed. Pathologic evaluation revealed a pancreatic head adenocarcinoma (T3-N1-M0). GP is a rare entity that should be suspected in patients with a history of heavy alcohol consumption who complain of chronic abdominal pain and weight loss. Patients without a clear diagnosis even after a through imaging work-up, or those in whom symptoms are persistent in spite of medical therapy, should undergo surgical exploration.
