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.

A Clinical Study Of Gastric Outlet Obstruction

Background:Diagnosis of Gastric outlet obstruction (GOO) is a challenge in 3rd world countries. Gastric outlet obstruction occurs because of impeding emptying of stomach mechanically, and it has varied causes. This study was taken up to know the etiological factors and management. Material And Methods:This was a descriptive prospective study done at Smt. NHL Municipal Medical College for a period of 2years from June 2019 to May 2021. A set of inclusion and exclusion criteria were defined and followed. Upper gastrointestinal endoscopy (OGD) was done in all cases w hile Barium meal study was done in a few cases to make the diagnosis. Relevant operative procedure was done, and patients were managed post operatively. Result:Cicatrised Duodenal ulcer (DU) was the commonest cause followed by Carcinoma Pyloric antrum (Ca PA). Majority of the patients were males (68%) with male to female ratio of 2.13:1. Vomiting was one of the major presenting symptoms in all the patients. Conclusion:Cicatrised DU was the commonest cause for GOO in present study. Present study highlights the increasing incidence of Ca PA. This could be due to better management of DU at an early stage.

Therapeutic value of double endoscopic bypass for malignant gastric outlet obstruction and biliary obstruction (with video) / 中华消化内镜杂志

Objective:To evaluate the safety and feasibility of double endoscopic bypass, namely endoscopic ultrasound-guided gastroenterostomy (EUS-GE) combined with endoscopic ultrasound-guided biliary drainage (EUS-BD), for malignant gastric outlet and biliary obstruction.Methods:A retrospective analysis was conducted on data of 10 patients with malignant gastric outlet and biliary obstruction who were not suitable for surgery or endoscopic retrograde cholangiopancreatography (ERCP) and treated by double endoscopic bypass in Nanjing Drum Tower Hospital from August 2017 to October 2020. The completion of therapy, clinical efficacy and post-procedure adverse events were analyzed.Results:Ten patients with different malignant cancer successfully underwent EUS-GE and EUS-BD, with procedure time of 60.5±22.3 min (30-100 min). There were no postoperative adverse events. EUS-GE was clinically successful in all 10 cases. Of the 10 EUS-BD cases, 9 were clinically successful, and 1 did not meet the criteria of clinical success. The median follow-up was 71 (37-120) days. None of the 10 patients had recurrent gastric outflow tract obstruction or biliary tract obstruction.Conclusion:Double endoscopic bypass is feasible and effective for patients with malignant gastric outlet and biliary obstruction and without surgery or ERCP opportunity.

Sarcina Ventriculi of Gastrointestinal Tract: A Clinicopathologic Study

Background: Sarcina ventriculi, a gram-positive coccus, are occasionally found in gastric biopsies. Although Sarcina had been described more than 150 years ago, little is known about its pathogenicity in humans. Method: This retrospective case series included patients who were identified with Sarcina infection. We report clinicopathologic characteristics of 13 patients with Sarcina in gastric or duodenal biopsies. Result: The presenting symptoms included: epigastric discomfort (n=6), epigastric pain (n=4), anorexia (n=6), nausea and vomiting (n=5), constipation (n=2), diarrhoea (n=2) and weight loss (n=3).All patients had evidence of mucosal injury.Sarcina was found on mucosal surface.12 patients had food residue on oesophagogastroduodenoscopy (OGD). 10 patients had gastric outlet obstruction (GOO), antral narrowing in 7 and duodenal obstruction in 3. 6 patients had malignant GOO. Causes of benign GOO included Helicobacter Pylorigastritis (n=1), eosinophilic gastritis (n=1) and duodenal ulcers (n=2, 1 NSAIDs). Of the 5 patients that had follow-up OGD, 2 had gastric residue. One patient had recurrence of symptoms with the persistence of sarcina on biopsy at 3 months. Symptoms improved at 6 months and no evidence of sarcina on biopsy at 6 months. Conclusion: Our findings suggest GOOcan be considered as a predisposing factor for Sarcina infection. Sarcina infection may not be the aetiology for GOObut may complicate recovery and may lead to life-threatening complications. Clinicians and pathologists must be aware of such microorganisms and must be documented in the histology report for further investigation and therapeutic consideration.

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.

Acid corrosive injury of stomach: management and long-term outcome

Background: Acid corrosive injury to stomach is not uncommon in India due to easy availability. Corrosive ingestion results in significant morbidity. We present our experience in surgical management of such cases. The aims and objectives of this study to review the experience of surgical management of gastric corrosive injury and to assess long term outcome and functional results.Methods: This study was retrospective analysis of prospectively collected data of 23 cases of acid corrosive injury managed in a single surgical unit.Results: Median age was 31 years, male to female ratio was 12:11. Surgical procedures were tailored according to extent and degree of stricture. Posterior gastrojejunostomy was done in 8 (38.0%) cases, near total gastrectomy in 3 (14.3%) cases, total gastrectomy and Billroth I in 2 (9.5%) cases each. 4 cases were lost to follow up after preliminary feeding jejunostomy. 2 cases had mortality after feeding jejunostomy. 2 cases were managed successfully without active surgical intervention. All patients undergoing definitive procedure had good results in terms of nutritional status and symptoms of gastric outlet obstruction.Conclusions: The outcome of gastric stricture secondary to acid ingestion can be significantly improved by adequate preoperative preparation and planned approach depending upon type of injury.

A rare cause of gastric outlet obstruction

Gastric outlet obstruction is the clinical and pathophysiological consequence of any disease process that produces mechanical impediment to gastric emptying. It may be acute from inflammatory swelling and peristaltic dysfunction or chronic from cicatrix. Chronic inflammation of the duodenum may lead to recurrent episodes of healing followed by repair and scarring ultimately leading to fibrosis and stenosis of the duodenal lumen. We would like to present a unique case of an elderly lady presenting with intractable vomiting over 3 months, gradually progressive which aggravated on consuming solids initially to consuming liquids later. After thorough investigations a provisional diagnosis of chronic duodenal ulcer with gastric outlet obstruction probably due to cicatrix was made. On laparotomy there was a chronic scarred duodenal ulcer following a previously contained perforation which was causing the gastric outlet obstruction. Cholecystectomy, duodenoplasty and loop gastrojejunostomy was performed with no complications post-operatively. This is a rare case of previous contained duodenal perforation causing gastric outlet obstruction.

Annular pancreas in adults: single unit experience from a tertiary care centre of Northern India

Annular pancreas is a rare congenital anomaly which usually presents with gastrointestinal symptoms early in life. In adults mostly it remains asymptomatic or may present with abdominal or features of duodenal obstruction the increased diagnosis of which is attributed to the improved imaging modalities. We hereby report our experience of adult annular pancreas in whom clinical presentation initially mimicked gastric or duodenal outlet obstruction. Adult annular pancreas was diagnosed with the aid of computed tomography of the abdomen and treated successfully with Roux-en-Y isoperistaltic gastrojejunostomy.

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.

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.

Clinical value of X-ray guided endoscopic gastrojejunostomy using stent ( with video) / 中华消化内镜杂志

Objective To evaluate the efficacy and safety of X-ray guided endoscopic gastrojejunostomy using stent in treatment of malignant gastric outlet obstruction ( GOO ) . Methods Six hospitalized patients with malignant GOO underwent X-ray guided endoscopic gastrojejunostomy using stent in the department of gastroenterology, Shandong Provincial Hospital Affiliated to Shandong University between March 2017 and June 2017. The technical success rate, clinical success rate, procedure time, adverse events and follow-up were recorded and analyzed in this retrospective study. Results The stent was successfully placed in the 6 patients with 100％ ( 6/6) technical success rate. The mean procedure time was 91. 7±51. 8 min. After the procedure, all patients were fed liquid or semi-liquid diet, and the GOO score system was increased from 0-1 before operation to 2-3 after operation. The clinical success rate was 100％(6/6). Peritonitis was observed in 2 patients during operation, and resolved by abdominal drainage. Gastrointestinal bleeding occurred in 1 patient after operation, which was resolved with conservative treatment. During a mean follow-up period of 78. 6 days (range 32-100 days), there was no recurrence of obstruction symptoms except that 1 patient died because of tumor progress 60 days after procedure. Conclusion The X-ray guided endoscopic gastrojejunostomy using stent is feasible and safe to treat malignant GOO with a reliable short-term efficacy.

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.

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.

Liquid Fire In The Stomach A Minimally Invasive Approach

Corrosive injuries are common in developing countries. Acid ingestion is more common in developing countries when compared to alkali ingestion in developed countries. Ingestion may be accidental or suicidal. The nature of the corrosive ingested determines the extent of injury caused. Acidic injury commonly affects stomach than alkalis and it ranges from acute to chronic gastric injuries. In this article we discuss about the management of corrosive stricture of pylorus of stomach which was dealt by laparoscopy.

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.

Percutaneous placement of H-configured triple biliary and enteral stents through a single access: A solution for complex bilio-enteric obstruction

A 75-year-old male with recurrent pancreatic adenocarcinoma after a previous Whipple's procedure presented with jaundice. The local advancement of the tumor caused obstructions of the common bile duct, intrahepatic bile duct hilum, and small bowel. Endoscopic stent insertion was precluded by the Roux-en-Y reconstruction. A successful transhepatic percutaneous single-access stenting of the whole biliary tree and intestine was achieved by H-configured triple stenting by combining T-configured dual stent placement in the biliary system with a duodenal stent insertion across the bottom of the anastomosis after looping a wire in the afferent limb. The ‘H-configured’ stents remained patent for 10 months without major or minor complications. This technique adds a new minimal-invasive and effective palliative option for patients with obstruction of a bilio-enteric anastomosis inaccessible to endoscopy.

Comparison with different scoring system for preoperative nutritional status of gastric cancer patients with pyloric obstruction / 天津医药

@#Objective To compare patient generated subjective global assessment (PG-SGA) and nutritional risk screening table (NRS2002) scoring systems in preoperative nutritional status assessment of patients with advanced gastric cancer and pyloric obstruction. Methods A total of 114 patients from the Department of Gastric Surgery of the Liaoning Cancer Hospital were selected between July 2016 and July 2017. All patients were confirmed gastric cancer with outlet obstruction by gastroscopy and histopathology. All patients were treated with PG-SGA, NRS2002 scoring systems were used to assess the preoperative nutritional status. The serum albumin <30 g/L was used as the gold standard for the diagnosis of malnutrition. The receiver operating characteristic (ROC) curve was used to analyze the sensitivity and specificity of PGSGA and NRS2002 scoring systems in patients with preoperative evaluation of nutritional status of gastric cancer with pyloric obstruction. Results Eighty cases (70.1%) were diagnosed as malnutrition by serum albumin in 114 patients. The area under the PG-SGA curve (AUC) was 0.858 and NRS2002 was 0.706. The sensitivity of PG-SGA to preoperative diagnosis of malnutrition in patients with advanced gastric cancer and pyloric obstruction was 88.75%, NRS2002 was 77.50%, the specificity of PG-SGA was 85.29%, and NRS2002 was 76.47%. Conclusion The PG-SGA scoring system is more suitable for the assessment of preoperative nutritional status in patients with advanced gastric cancer and pyloric obstruction, and has a high diagnostic efficiency.
