Síndrome pilórico en un body packer / Pyloric syndrome in a body packer

Introducción. El embalaje y transporte de estupefacientes dentro del organismo, o body packing, es una práctica frecuente en Centroamérica y el Caribe. Además del riesgo de muerte por la exposición a las sustancias tóxicas, existe el riesgo de complicaciones mecánicas con indicación de manejo quirúrgico. El Hospital de Engativá, por su cercanía al aeropuerto de Bogotá, D.C., Colombia, es el centro de referencia para el tratamiento de estos pacientes. Caso clínico. Un hombre de 65 años traído al hospital por un episodio emético con expulsión de cuatro cápsulas para el transporte de estupefacientes. Al examen físico se encontraron masas palpables en el hemiabdomen superior, sin abdomen agudo. La tomografía de abdomen informó un síndrome pilórico secundario a retención gástrica de cuerpos extraños. Fue llevado a laparotomía y gastrotomía logrando la extracción de 97 objetos cilíndricos de látex que contenían sustancias ilícitas. Discusión. En los body packer asintomáticos, la administración de soluciones laxantes es una estrategia terapéutica segura. Los casos reportados de obstrucción gastrointestinal son infrecuentes y se relacionan con la ingesta de un gran número de cápsulas, por lo que es necesario el tratamiento quirúrgico. Conclusión. El síndrome pilórico es una presentación infrecuente en un body packer. Se debe tener un alto índice de sospecha para garantizar un manejo oportuno

Introduction. Packaging and transportation of narcotic drugs inside a human body, or body packing, is a frequent practice in Central America and the Caribbean. In addition to the risk of death due to exposure to toxic substances, there is a risk of mechanical complications with an indication for surgical management. The Engativá Hospital, due to its proximity to the airport in Bogotá, D.C., Colombia, is the reference center for the treatment of these patients. Clinical case. A 65-year-old man brought to the hospital for an emetic episode with expulsion of four narcotic transport capsules. Physical examination revealed palpable masses in the upper abdomen, without an acute abdomen. Abdominal tomography revealed pyloric syndrome secondary to gastric retention of foreign bodies. He was taken to laparotomy and gastrotomy, achieving the extraction of 97 cylindrical latex objects that contained illicit substances. Discussion. In asymptomatic body packers, the administration of laxative solutions is a safe therapeutic strategy. Reported cases of gastrointestinal obstruction are infrequent and are related to the ingestion of a large number of capsules, for which surgical treatment is necessary. Conclusion. Pyloric syndrome is an uncommon presentation in body packers. A high index of suspicion is required to ensure timely management

Síndrome de Bouveret como variante de íleo biliar / Bouveret syndrome as a variant of gallstone ileus

Introducción. El síndrome de Bouveret es una variante del íleo biliar, de rara presentación dentro de las causas de obstrucción intestinal, generada por la impactación de un lito biliar a nivel del duodeno, secundario a la formación de una fístula bilioentérica. Es más común en mujeres en la octava década de la vida, con múltiples comorbilidades. y presenta síntomas inespecíficos, documentándose la triada de Rigler hasta en el 80 % de las tomografías de abdomen. La cirugía sigue siendo el tratamiento de elección. Caso clínico. Presentamos el caso de una paciente de 76 años, con múltiples antecedentes y cuadros previos de cólico biliar, que consultó por dolor abdominal y signos de hemorragia de vías digestivas altas y se documentó un síndrome de Bouveret. Fue tratada en la misma hospitalización mediante extracción quirúrgica del cálculo con posterior resolución de su sintomatología.Conclusión. A pesar de que el síndrome deBouveret es una entidad de infrecuente presentación, los cirujanos generalesdeben estar familiarizados con esta patología, en el contexto del paciente que consulta con un cuadro de obstrucción intestinal, conociendo el valor de la tomografía de abdomen y la endoscopia de vías digestivas altas, teniendo en cuenta la edad y las condiciones del paciente para definir el manejo quirúrgico más adecuado.

Introduction. Bouveret's syndrome is a variant of gallstone ileus, of rare presentation within the causes of intestinal obstruction, generated by the impaction of a biliary stone at the level of the duodenum, secondary to the formation of a biliary-enteric fistula. It is more common in women in the eighth decade of life, with multiple comorbidities, and presents non-specific symptoms, with Rigler's triad being documented in up to 80% of abdominal CT scans. Surgery remains the treatment of choice. Clinical case. We present the case of a 76-year-old patient, with history of multiple episodes of biliary colic, who consulted for abdominal pain and signs of upper gastrointestinal bleeding. Bouveret's syndrome was documented. She was treated in the same hospitalization by surgical extraction of the stone with subsequent resolution of her symptoms. Conclussion. Although Bouveret's syndrome is an entity of infrequent presentation, general surgeons must be familiar with this pathology in the context of the patient who presents with intestinal obstruction, knowing the value of abdominal tomography and upper GI endoscopy, taking into account the age and conditions of the patient to define the most appropriate surgical management.

Gastric outlet obstruction following recurrent Pancreatitis uncovers a Giant Parathyroid Adenoma: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#A 35-year-old female presented with abdominal pain, fever, projectile vomiting, and a diffuse tender epigastric mass. She was diagnosed to have acute persistent pancreatitis with a pancreatic pseudocyst. Elevated serum calcium levels provided an etiologic link between hypercalcemia and pancreatitis. On examination, a nodule was found in the left side of her neck which was later diagnosed as a giant left inferior parathyroid adenoma. This report highlights the critical analysis of history, examination, and investigations to reach an ultimate diagnosis. Pseudocyst drainage and parathyroidectomy resolved her symptoms.

Tratamiento endoscópico de la obstrucción del tracto de salida gástrico de origen péptico-cicatricial en un niño de 4 años / Endoscopic treatment of cicatricial pyloric stenosis of peptic origin in a 4-year-old boy

La obstrucción de la salida gástrica es una afección infrecuente en la edad pediátrica. Tradicionalmente, la cirugía ha sido el modo de tratamiento estándar, pero está asociada a mayor morbimortalidad. El tratamiento endoscópico ha surgido como una alternativa al tratamiento convencional. Presentamos el caso de un paciente de 4 años con estenosis prepilórica secundaria a enfermedad ulceropéptica. El cuadro clínico empezó con vómitos y dolor abdominal de 2 meses de evolución. Frente a la falta de respuesta al tratamiento médico y a la dilatación endoscópica con balón, se realizaron incisiones radiadas con electrocauterio e inyecciones de esteroides. La terapéutica endoscópica con balón debería ser el primer gesto terapéutico en este tipo de estenosis refractarias al tratamiento médico

Gastric outlet obstruction is an uncommon condition in children. Traditionally, surgery has been the standard mode of treatment, but it is associated with higher morbidity and mortality. Endoscopic treatment has emerged as an alternative to conventional treatment. We present the case of a 4-year-old patient with refractory prepyloric stenosis secondary to peptic ulcer disease. The picture begins with vomiting and abdominal pain of 2 months of evolution. Pre-pyloric stenosis was confirmed. Faced with the lack of response to medical treatment and balloon dilation, radiated incisions were made with electrocautery and steroid injections. When medical treatment is not sufficient, endoscopic balloon therapy should be the first therapeutic gesture in this type of stenosis; given its refractoriness, we believe it is important to highlight the usefulness of endoscopic treatment, which could prevent surgery and associated morbidity and mortality.

Obstrução gástrica por bezoar / Gastric obstruction due to bezoar

A obstrução por bezoar é um acúmulo de material parcialmente ou não digerido no estômago. Bezoares gástricos são raros e ocorrem com mais frequência em pacientes com transtornos de comportamento, esvaziamento gástrico anormal ou após cirurgia gástrica. Podem ser assintomáticos ou apresentar sintomas como dor abdominal e vômitos incoercíveis. Podem ainda ter composições diversas e ocorrer em todas as faixas etárias. O objetivo deste relato foi demonstrar um caso de bezoar gástrico em paciente previamente submetido à cirurgia bariátrica e internado com quadro de vômitos incoercíveis e hemorragia digestiva alta, com a demonstração de que sua resolução completa ocorreu na realização da segunda endoscopia.

Bezoar obstruction is an accumulation of partially digested or undigested material in the stomach. Gastric bezoars are rare and occur more frequently in patients with behavioral disorders, abnormal gastric emptying, or after gastric surgery. They may be asymptomatic or present with symptoms such as abdominal pain and incoercible vomiting. They can have diverse compositions and occur in all age groups. The aim of this report was to demonstrate a case of gastric bezoar in a patient who previously underwent a bariatric surgery and was hospitalized with incoercible vomiting and upper gastrointestinal hemorrhage, with the demonstration that its complete resolution occurred during the second endoscopy.

Gastric outlet obstruction as manifestation of eosinophilic gastroenteritis / Obstrucción gástrica como manifestación de gastroenteritis eosinofílica

RESUMEN La gastroenteritis eosinofílica (EG) es una entidad poco frecuente. Presentamos un varón de 55 años sin antecedentes de atopía ni alergia, que presentó dolor abdominal y vómitos. La tomografía computarizada abdominal y la ecoendoscopia demostraron engrosamiento de la pared gástrica con engrosamiento de la pared del duodeno superior, sin masa definida ni colección de líquido. La endoscopia gastrointestinal confirmó engrosamiento de pliegues prepilóricos y duodeno superior con estenosis luminal. Se realizó gastrectomía parcial por ausencia de diagnóstico definitivo y sospecha de posible malignidad y diagnóstico de obstrucción de la salida gástrica. La histopatología fue compatible con EG, tratada con un tratamiento con corticoides de 8 semanas de duración, mostró mejoría clínica, aumento de peso y normalización del recuento de eosinófilos en sangre periférica.

ABSTRACT Eosinophilic gastroenteritis (EG) is a rare entity. We report a 55-year-old man had no previous atopy or allergic history, who presented abdominal pain and vomiting. Abdominal computed tomography and endoscopy ultrasonography demostrated gastric wall thickening with wall thickening of the superior duodenum, without defined mass or fluid collection. Gastrointestinal endoscopy confirmed thickening of prepyloric folds and superior duodenum with luminal stenosis. Parcial gastrectomy was performed due to absence of definitive diagnosis and suspicion of possible malignancy and diagnosis of gastric outlet obstruction. Histopathology was compatible with EG, treated with an 8-week long corticosteroid therapy, showed clinical improvement, weight gain and normalization of eosinophil count on peripheral blood.

Disseminated Tuberculosis Presenting as Gastric Outlet Obstruction

@#A 12-year-old female had a three-year history of fever, non-bilious vomiting and abdominal pain. Upper gastrointestinal series showed a filling defect at the duodenum. Esophagogastroduodenoscopy exhibited circumferential mass extending from the duodenal bulb to the 2nd part of the duodenum which on histology disclosed chronic granulomatous inflammation. Chest X-ray suggested miliary tuberculosis; endotracheal tube aspirate was PCR positive for Mycobacterium tuberculosis. Patient was diagnosed as disseminated tuberculosis of the duodenum and lungs. Quadruple anti-tuberculosis medication was started but patient succumbed to nosocomial sepsis.

Complicaciones del uso de prótesis metálicas autoexpansibles como paliación de obstrucción maligna del tracto de salida gástrico / Complications of the use of self-expanding metal stents as paliation of malignant obstruction of the gastric outlet tract

RESUMEN La colocación de prótesis metálicas autoexpansibles (PMA) constituye una forma de tratamiento común en las obstrucciones malignas al tracto de salida gástrico, pues consigue la resolución de los síntomas a corto plazo, con un riesgo aceptable de complicaciones. Objetivo: Evaluar la ocurrencia de complicaciones del procedimiento y su tratamiento. Métodos: Este trabajo tuvo un componente descriptivo sobre las complicaciones del uso de prótesis y su tratamiento y un componente de asociación respecto a la administración del tratamiento oncológico con intención paliativa y su resultado respecto a la supervivencia global. Se revisaron 150 pacientes desde enero de 2011 hasta julio de 2017 que requirieron este procedimiento en el Instituto Nacional de Cancerología (INC). Resultados: La etiología que más frecuentemente causó obstrucción del tracto de salida gástrico fue el cáncer de estómago, seguido del cáncer pancreatoduodenal, tumores malignos de la vía biliar y otros, incluso fuera del sistema digestivo. Se documentó un porcentaje de éxito técnico del 98,6% (148/150) y éxito clínico del 96% (146/150). Se identificó un 64% (N=96) de pacientes con enfermedad maligna en estadio IV y que tuvieron una incidencia de complicaciones tempranas del 11,33% (N=17) y tardías del 29,33% (N=44). La mayor parte de las complicaciones fueron tratadas por vía endoscópica y el 2,66% (N=4) de los pacientes necesitaron tratamiento quirúrgico. Conclusiones: Las complicaciones de la colocación de prótesis duodenales pueden ser manejadas en forma exitosa por vía endoscópica en la mayoría de los casos. Los pacientes que además de la colocación de prótesis recibieron tratamiento oncológico presentaron una mayor supervivencia estadísticamente significativa.

ABSTRACT The placement of self-expanding metallic stents (SEMS) is a common form of treatment in malignant obstructions to the gastric outlet tract, achieving the resolution of symptoms in the short term and with an acceptable risk of complications; It is convenient to know and the detail of its use and how to treat them. The objective of this publication was to evaluate the occurrence of complications of the procedure and its treatment. Methods: The work had a descriptive component on the treatment of the use of prosthesis and its treatment and another of association with respect to the administration of oncological treatment with palliative intention and its result with respect to survival; In a retrospective manner, 150 patients were reviewed from January 2011 to 25July 2017, who required this procedure at the National Institute of Cancerology, in Bogotá, Colombia. Results: A 64% (N = 96) of patients with stage IV disease were identified, which had an incidence of early complications of 11.33% (N = 17) and late complications 29.33% (N 29= 44). A technical success rate of 98.6% (148/150) and clinical success of 96% (146/150) was documented. Most of the complications were treated endoscopically and 2.66% (N = 4) patients needed surgical treatment. Conclusions: Complications of duodenal stent placement can be successfully managed endoscopically in most cases. Patients who, in addition to prosthesis placement, received oncological treatment had a statistically significant higher survival rate.

Endoscopic Management of Combined Biliary and Duodenal Obstruction

Combined obstruction of the bile duct and duodenum is a common occurrence in periampullary malignancies. The obstruction of gastric outlet or duodenum can follow, occur simultaneously, or precede biliary obstruction. The prognosis in patients with combined obstruction is particularly poor. Therefore, minimally invasive palliation is preferred in these patients to avoid morbidity associated with surgery. Endoscopic palliation is preferred to surgical bypass due to similar efficacy, less morbidity, and shorter hospital stay. The success of endoscopic palliation depends on the type of bilioduodenal stenosis and the presence of previously placed duodenal metal stents. Biliary cannulation is difficult in type II bilioduodenal strictures where the duodenal stenosis is located at the level of the papilla. Consequentially, technical and clinical success is lower in these patients than in those with type I and III bilioduodenal strictures. However, in cases with failure of endoscopic retrograde cholangiopancreatography, with the introduction of endoscopic ultrasound for biliary drainage, the success of endoscopic bilioduodenal bypass is likely to increase further. The safety and efficacy of endoscopic ultrasound-guided drainage has been documented in multiple studies. With the development of dedicated accessories and standardization of drainage techniques, the role of endoscopic ultrasound is likely to expand further in cases with double obstruction.

A Man with Dysphagia after Cervical Esophagogastrostomy: A Case Report / 대한연하장애학회지

Dysphagia caused by a functional gastric outlet obstruction is rare and the natural course of a functional gastric outlet obstruction is unclear. This paper reports a patient with dysphagia and a functional gastric outlet obstruction after a cervical esophagogastrostomy. A 62-year-old man with a history of esophageal cancer and cervical esophagogastrostomy presented with dysphagia and discomfort during meals. A videofluoroscopic swallowing study (VFSS) with barium revealed a mild increase in the post-swallow remnants and delayed emptying of the gastric outlet, reflecting a functional gastric outlet obstruction at the diaphragm. One month later, VFSS revealed a worsened functional gastric outlet obstruction at the diaphragm. A delayed chest X-ray showed worsened delayed emptying of the gastric outlet. A cervical esophagogastrostomy for early esophageal cancer can cause functional gastric outlet obstruction, presenting as dysphagia and discomfort during meals. Physicians should be concerned about dysphagia and the functional changes in the esophagus in patients with a cervical esophagogastrostomy.

Endoscopic Ultrasound-Guided Biliary Drainage for Benign Biliary Diseases

Although endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for benign biliary diseases, this procedure is technically difficult in some conditions such as a surgically altered anatomy and gastric outlet obstruction. After a failed ERCP, a surgical or a percutaneous approach is selected as a rescue procedure; however, various endoscopic ultrasound (EUS)-guided interventions are increasingly utilized in pancreatobiliary diseases, including EUS-guided rendezvous for failed biliary cannulation, EUS-guided antegrade treatment for stone management, and EUS-guided hepaticogastrostomy for anastomotic strictures in patients with a surgically altered anatomy. There are some technical hurdles in EUS-guided interventions for benign biliary diseases owing to the difficulty in puncturing a relatively small bile duct and in subsequent guidewire manipulation, as well as the lack of dedicated devices. A recent major advancement in this field is the introduction of a 2-step approach, in which EUS-guided drainage is placed in the first session and antegrade treatment is performed in subsequent sessions. This approach allows the use of various techniques such as mechanical lithotripsy and cholangioscopy without a risk of bile leak. In summary, EUS-guided interventions are among the treatment options for benign biliary diseases; however, standardization of the procedure and development of a treatment algorithm are needed.

Endoscopic Palliation for Biliary and Pancreatic Malignancies: Recent Advances

Malignancies of the pancreatobiliary system are usually unresectable at the time of diagnosis. As a consequence, a majority of these cases are candidates for palliative care. With advances in chemotherapeutic agents and multidisciplinary care, the survival rate in pancreatobiliary malignancies has improved. Therefore, there is a need to provide an effective and long-lasting palliative care for these patients. Endoscopic palliation is preferred to surgery as the former is associated with equal efficacy and reduced morbidity. The main role of endoscopic palliation in the vast majority of pancreatobiliary malignancies includes biliary and enteral stenting for malignant obstructive jaundice and gastric outlet obstruction, respectively. Recent advances in endoscopic palliation appear promising in imparting long-lasting relief of symptoms. Use of radiofrequency ablation and photodynamic therapy in malignant biliary obstruction has been shown to improve the survival rates as well as the patency of biliary stents. The emergence of endoscopic ultrasound (EUS) as a therapeutic tool has enhanced the capability of minimally invasive palliation in pancreatobiliary cancers. EUS is a valuable alternative to endoscopic retrograde cholangiopancreatography for the palliation of obstructive jaundice. More recently, EUS is emerging as an effective primary modality for biliary and gastric bypass.

Multiple Congenital Pancreatic Cysts in a Neonate

Congenital pancreatic cysts are rare in newborn babies, and this makes prenatal diagnosis difficult. Diagnosis can be delayed for a few months after birth until the infant presents with an abdominal mass, abdominal distension, or vomiting due to gastric outlet obstruction. Excision of the cyst is the treatment of choice. A congenital pancreatic cyst should be considered if the fetus has an abdominal cyst without a definite origin. A prompt diagnosis is crucial to prevent fatal complications such as cholangitis, pancreatitis, cyst rupture, and peritonitis. We report a case of neonate with multiple congenital pancreatic cysts suspected prenatally to be stomach diverticulum or duplication cysts of the intestine.

Establishment and clinical application of modified endoscopic freka trelumina placement / 中华胃肠外科杂志

OBJECTIVE@#To establish a modified endoscopic Freka Trelumina placement (mEFTP) for modifying or substituting the traditional endoscopic Freka Trelumina placement (EFTP) and to explore the safety and feasibility of mEFTP in patients requiring enteral nutrition and gastrointestinal decompression in general surgery.@*METHODS@#A retrospective cohort study was conducted to analyze the clinical data of patients undergoing EFTP or mEFTP at General Surgery Department of 920 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2016 to January 2018.@*INCLUSION CRITERIA@#the function of lower digestive tract was normal; patients who could not eat through mouth or nasogastric tube needed to have enteral nutrition and gastrointestinal decompression; the retention time of Freka Trelumina (FT) was not expected to exceed 2 months.@*EXCLUSION CRITERIA@#contraindication for gastroscopy; suspected shock or digestive tract perforation; suspected mental diseases; infectious diseases of digestive tract; thoracoabdominal aortic aneurysm. mEFIP procedure was as follow. FT was inserted into stomach through one side nasal cavity, gastroscope was inserted into stomach cavity, and the front part of FT was clamped with biopsy forceps through biopsy hole. Biopsy forceps and FT were inserted into the pylorus or anastomosis under gastroscope, and they were pushed into the duodenum or output loop. During pushing, the gastroscope did not pass through the duodenum or output loop. The biopsy forceps was released and pushed out, and FT was pushed with biopsy forceps synchronously into the duodenum or output loop more than 5 cm. The foreign body forceps was inserted through the biopsy hole, and the FT tube was held in the stomach and pushed to the duodenum or output loop. The previous steps repeated until the suction cavity reached the pylorus or anastomosis. The gastroscope was exited gently; the guide wire was pulled out slowly. EFTP procedure: foreign body forceps was used to clamp the front part of FT, and gastroscope, foreign body forceps and FT pass the pylorus or anastomosis simultaneously to reach the descendent duodenum or output loop as a whole. The time of catheterization was recorded and position of FT was examined by X-ray within 1 h after catheterization. The success rate of catheterization and morbidity of complications after catheterization were evaluated and compared between the two groups.@*RESULTS@#A total of 141 patients were enrolled, 72 in the mEFTP group and 69 in the EFTP group. In mEFTP group, 45 cases were males and 27 were females with an average age of 55.8(37-76) years; 27 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 17 cases, due to rectal cancer in 10 cases) and 45 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 18 cases and anastomotic block after gastroenterostomy in 27 cases). In the EFTP group, 41 were males and 28 were females with an average age of 55.3(36-79) years; 33 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 20 cases, due to rectal cancer in 13 cases) and 36 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 15 cases and anastomotic block after gastroenterostomy in 21 cases). In patients with normal upper digestive tract anatomy, the average catheterization time of mEFTP was (4.9±1.7) minutes which was shorter than (7.6±1.7) minutes of EFTP(t=6.683, P0.05). In patients with upper gastrointestinal anatomic changes, the success rate of catheterization in mEFTP was even higher than that in EFTP, but the difference was not significant [97.8%(41/45) vs. 86.1%(31/36), χ²=2.880, P=0.089]; while the morbidity of catheterization complication in mEFTP was lower than that in EFTP [0 vs. 8.3%(3/36), χ²=3.894, P=0.048].@*CONCLUSIONS@#Whether the upper gastrointestinal anatomy is normal or not, mEFTP presents shorter catheterization time, higher success catheterization rate than EFTP, and is safety. mEFTP can be widely applied to clinical practice for patients requiring enteral nutrition and gastrointestinal decompression.

Peptic Ulcer-related Stenosis

Peptic ulcer disease involves breakdown of the epithelial lining of the stomach or duodenum. Stenosis and associated gastric outlet obstruction is the least frequent complication of peptic ulcer disease. Most cases of stenosis occur because of duodenal or pyloric cannel ulceration. Although etiologies of peptic ulcer disease and the affected patient populations have changed, the most common etiologic factors remain Helicobacter pylori infection and use of non-steroidal anti-inflammatory drugs. In recent years, eradication of H. pylori and the use of proton pump inhibitors have reduced the incidence of complications. Because the predominant cause of gastric outlet obstruction has increasingly been attributed to malignant cancer in recent years, endoscopic examination is important to differentiate benign peptic stenosis from malignant stenosis. Medical treatment such as acid-reducing drugs or H. pylori eradication is the mainstay of treatment. Endoscopic dilation or surgical management may be considered in cases of refractory or recurrent stenosis despite medical treatment. Among the major complications of peptic ulcer disease, this report will provide an overview of peptic ulcer-related stenosis.

Fitobezoar posterior a mini bypass gástrico por laparoscopia / Phytobezoar after mini gastric bypass

Introducción. La miniderivación (mini-bypass) gástrica por laparoscopia es un procedimiento bariátrico que recientemente ha cobrado popularidad. Las alteraciones del tubo digestivo generadas por estos procedimientos pueden ocasionar diversas complicaciones, algunas raras, como los bezoares.Caso clínico. Se presenta el caso de una mujer de 52 años de edad con antecedentes de diabetes mellitus y obesidad, que fue tratada con una miniderivación gástrica por laparoscopia. Nueve meses después del procedimiento, presentó dolor en el epigastrio, intolerancia a los alimentos y vómito, por lo cual se dio tratamiento sintomático sin obtener mejoría. Se practicó una endoscopia de vías digestivas altas, cuyo hallazgo fue un bezoar de coco que obstruía parcialmente la anastomosis. El bezoar se trituró y se extrajo por endoscopia. Discusión. Los pacientes con antecedentes de cirugía bariátrica tienen mayor riesgo de presentar bezoares por la modificación del tubo digestivo. Estos pacientes presentan frecuentemente síntomas de dispepsia, por lo que la sintomatología inespecífica puede confundirse o subestimarse. Se debe considerar practicar una endoscopia en todos aquellos con antecedentes de cirugía bariátrica que presenten vómito persistente después de ingerir alimentos o síntomas de obstrucción gástrica

Introduction: Laparoscopic Mini-gastric bypass is a bariatric procedure that has gained popularity recently. Alterations to the gastrointestinal tract anatomy created during these procedures, may lead to several complications, some of them very rare, such as the bezoar. Presentation of case: A fifty-two years old female with type II diabetes mellitus and obesity was treated by laparoscopic mini-gastric bypass surgery. Nine months after her surgery she experienced epigastric pain, intolerance to food and vomiting with non-successful symptomatic treatment. One month later, the patient underwent an upper GI endoscopy which reported a coconut bezoar partially obstructing the anastomosis. Bezoar was broken into pieces and removed endoscopically. Two days after, patient returned to normal diet. Conclusion: Patients with bariatric surgeries have a higher risk of presenting such masses because of the gas-trointestinal tract modifications. Symptoms can be confused or overlooked in bariatric patients since there is a frequent complain of dyspeptic symptoms after such procedures. An endoscopy should be considered in every patient who underwent a bariatric procedure and presents with persistent vomiting after food ingestion and/or gastric outlet symptoms

Pseudoquiste pancreático intramural gástrico en páncreas heterotópico, una causa infrecuente de retención gástrica: caso clínico / Gastric intramural pseudocyst in a heterotopic pancreas causing gastric outlet obstruction: report of one case

Heterotopic pancreas is a silent gastrointestinal malformation that may become clinically evident when complicated by inflammation and pseudocyst formation. We report a 26 year-old male presenting with vomiting, pain and abdominal distention. An abdominal CT scan showed an important gastric distention secondary to a 4-cm cystic lesion located in the antrum wall. An endosonography showed that the lesion obstructed the gastric outlet and was compatible with a pseudocyst. A cysto-gastrostomy was performed draining the cyst. Its high lipase and amylase content confirmed that it was a pancreatic pseudocyst. Six months later, the lesion appeared again and a subtotal gastrectomy was performed Histopathology confirmed ectopic pancreatic tissue.

Endoscopic Balloon Dilation for Treatment of Congenital Antral Web / 대한소아소화기영양학회지

Congenital antral webs are a rare but relevant cause of gastric outlet obstruction in infants and children. The condition may lead to feeding refusal, vomiting, and poor growth. Due to the relative rarity of the disease, cases of congenital antral web are frequently misdiagnosed or diagnosed with significant delay as physicians favorably pursue diagnoses of pyloric stenosis and gastric ulcer disease, which are more prevalent. We report a case of an eight-month-old female who presented with persistent non-bilious emesis, feeding difficulties, and failure to thrive and was discovered to have an antral web. The web was successfully treated with endoscopic balloon dilation, which resolved her symptoms. Two years later, the patient remains asymptomatic and is thriving with weight at the 75th percentile for her age.

The vanishing stent: Repeated fracture and dissolution of nitinol gastric stents in a long term cancer survivor

Nitinol self expandable metal stents are increasingly utilised for malignant obstruction in the proximal gastrointestinal tract. We describe a case in which repeated fracture of proximal duodenal stents with dissolution of the nitinol wire skeleton and covering membranes occurred in a long term cancer survivor. This necessitated placement of 4 stents for symptom control and to allow oral feeding until the patient's death 20 months after the initial stent was inserted. Fracture of gastric and duodenal stents has rarely been described previously, some incidences of which were considered due to mechanical causes. Dissolution of stent metal skeletons has not previously been recognised in gastroduodenal stents but has been described in an oesophageal stent subject to reflux of gastric content and a biochemical mechanism has been proposed. With modern oncological treatment the prospect of patients outliving their stents is increasing and the need for repeat procedures should form part of the consent process.
