RESUMO

Digestive diseases are the fourth leading cause of outpatient care in Peruvian healthcare centers, with gastritis and peptic ulcers being the most common. This is a retrospective, cross-sectional, descriptive study of secondary analysis of medical record data to evaluate the prevalence of Helicobacter pylori in patients undergoing upper digestive endoscopy during 2019 at Clinica Delgado, Lima, Peru. An association between males (PRa 1.27, 95% CI 1.10-1.48, p<0.001), age categories and upper digestive endoscopy (PRa 2.53, 95% CI 2.16-2.97, p<0.001) was reported. Based on these findings, it is recommended that other causes of gastritis be identified, especially in young women with deep chronic gastritis. Furthermore, we present a review of the scientific literature of Peru on factors associated with the positivity of Helicobacter pylori in the results of superior digestive endoscopy.

RESUMO

RESUMEN Las enfermedades digestivas representan la cuarta causa de atención ambulatoria en los centros sanitarios peruanos, siendo la gastritis y las úlceras pépticas las más comunes. El presente es un estudio retrospectivo, de corte transversal, de tipo descriptivo, de análisis secundario de datos de historias clínicas, para evaluar la prevalencia de Helicobacter pylori en pacientes sometidos a endoscopia digestiva alta durante el año 2019 en la Clínica Delgado, Lima, Perú. Asociación entre el sexo masculino (PRa 1,27, IC95% 1,10-1,48, p <0,001), categorías de la edad y resultado de endoscopia digestiva alta (PRa 2,53, IC95% 2,16-2,97, p<0,001) fueron reportados. Se recomienda, a partir de estos hallazgos, determinar otras causas de gastritis, especialmente en las mujeres jóvenes con gastritis crónica profunda. Además, presentamos una revisión de la literatura científica del Perú sobre los factores asociados a la positividad de Helicobacter pylori en los resultados de la endoscopia digestiva superior.

RESUMO

OBJECTIVE: To evaluate the therapeutic success of the injection of N-butyl-2 cyanoacrylate in the treatment of gastric varices. METHODS: Cross-sectional study included 33 patients with gastric varices who only received cyanoacrylate endoscopic therapy between 2006 and 2010. Intravariceally, cyanoacrylate was injected in a 1:1 dilution with lipiodol until the obliteration of varices. The therapeutic situation was: active bleeding, varices with stigmata of recent bleeding and secondary prophylaxis. Treatment success was evaluated according to hemostasis, recurrent bleeding and obliteration. RESULTS: Of the 33 patients, 3 (9.1%) were for active bleeding, 20 (60.6%) with stigmata of recent bleeding and 10 (30.3%) as secondary prophylaxis. Gastric varices were GOV2, 17 (51.5%); IGV1, 14 (42.4%); GOV1, 2 (6.1%). Hemostasis was achieved in 21 (91.3%) and in 2 (66.7%) of 3 patients with active bleeding. Five (15.6%) patients had recurrent bleeding and 2 of them used cyanoacrylate with successful hemostasis. Obliteration was achieved. Four patients died and one for failure of control bleeding. A high severity of Child-Pugh classification was related to treatment endoscopic failure (p=0.034). The main complication was bleeding after the injection of cyanoacrylate. CONCLUSIONS: Our results support the use of cyanoacrylate in the treatment of gastric varices with few major complications.

RESUMO

OBJETIVO: Evaluar el éxito terapéutico de la inyección de N-butil-2-cianoacrilato en el tratamiento de las várices gástricas. MATERIALES Y MÉTODOS: Estudio transversal que incluyó 33 pacientes con várices gástricas que sólo recibieron terapia endoscópica con cianoacrilato entre el 2006 al 2010. El cianoacrilato fue inyectado intravaricealmente en una dilución 1:1 con lipiodol hasta obtener la obturación de las várices. La situación terapéutica fue: Hemorragia activa, várices con estigmas de sangrado reciente y profilaxis secundaria. El éxito del tratamiento se evaluó según la hemostasia, recurrencia de sangrado y obturación. RESULTADOS: De los 33 pacientes, 3 (9.1%) fueron por hemorragia activa, 20 (60.6%) con estigmas de sangrado reciente y 10 (30.3%) como profilaxis secundaria. Las várices fueron GOV2, 17 (51.5%); IGV1, 14 (42.4%) y GOV1, 2 (6.1%). Se logró hemostasia total en 21 (91.3%) pacientes con sangrado agudo o reciente y en 2 (66.7%) de 3 sujetos con sangrado activo. En 5 (15.6%) pacientes hubo recurrencia de sangrado y 2 de ellos recibieron cianoacrilato con éxito de hemostasia. Se logró obturación en 25 (75.8%) del total de pacientes. Cuatro pacientes fallecieron, uno por fracaso del control de sangrado. La mayor severidad de clasificación Child-Pugh se relacionó con falla terapéutica (p=0.034). La complicación principal fue el sangrado post-inyección del cianoacrilato. CONCLUSIONES: Nuestros resultados favorecen el uso de cianoacrilato en el tratamiento de várices gástricas, con raras complicaciones mayores.

RESUMO

Female of 64 years old, who two years ago was hospitalized in another institution for treatment of an abscess in the right liver lobe. During that hospitalization, it was found a duodenal tumor by tomography; however, no further studies or follow up on this finding was done. Prior to actual hospitalization, she was seen in a private clinic and treated with antibiotics for a suggestive"organized abscess" in the pancreatic head diagnosed by tomography. She presented with fever, abdominal pain and a palpable abdominal tumor in the right upper quadrant for a month. We realized a three-phase multislice spiral tomography with pancreatic curved reconstruction, which allowed to identified an ovoid tumor of 80 x 60 mm, with an area of central necrosis and intense contrast enhancement (arterial phase), located between the second and third duodenal portion, near the head of the pancreas. An upper endoscopy showed an extrinsic compression of the third duodenal portion. The patient underwent tumor resection without complication and the histologic diagnosis of the surgical specimen revealed a duodenal stromal tumor (GIST) with extraluminal transmural growth. We presented this case because of its unusual presentation of this tumor.

RESUMO

Paciente mujer de 64 años de edad, quien hace dos años estuvo hospitalizada en otra institución para el tratamiento de un absceso en el lóbulo hepático derecho. Durante esa hospitalización se diagnosticó un tumor duodenal por tomografía; sin embargo, no se completó el estudio sobre este hallazgo. Previa a la actual hospitalización, la paciente estuvo internada en una clínica privada, donde fue tratada con antibióticos por una imagen sugestiva de "absceso organizado" en la cabeza del páncreas. Desde hace un mes presentaba fiebre, dolor abdominal y una masa palpable en el cuadrante superior derecho del abdomen. Se le realizó una tomografía espiral multicorte trifásica, con reconstrucción curvada de páncreas que permitió reconocer una tumoración ovoidea de 80 x 60 mm, con área de necrosis central e intenso realce del contraste (fase arterial), localizada entre la segunda y tercera porción duodenal, próxima a la cabeza de páncreas. La endoscopía alta demostró una compresión extrínseca en la tercera porción duodenal. La paciente fue sometida a una resección tumoral sin complicaciones y la histología del espécimen quirúrgico reveló un Tumor Estromal Gastrointestinal (GIST) Duodenal, de crecimiento transmural extraluminal. Presentamos el caso por ser una inusual presentación este tipo de tumores.

RESUMO

The Vater's ampulla neoplasias are not very frequent lesions. The ampullectomy consists on the total resection of the Vater's ampulla and part of the duodenal wall with the later reconstruction and anastomosis of the common bile duct and the Wirsung's duct to the duodenum. The local resection of the ampulla is an alternative to the duodenopancreatectomy that has to be taken into account, especially in benign lesions as in the case of adenomas of the Vater's ampulla. Here we describe two cases one with adenoma of the Vater's ampulla, with a high degree dysplasia, who first underwent an ampullectomy and finally ended up in a duodenopancreatectomy due to the infiltration of the adenoma into the edge of section and other case of Lymphangioma of Vater's ampulla with no infiltration in the edge of section.

RESUMO

Fibrovascular polyps are extremely rare benign neoplasias of the esophagus, which usually originate in the lower cricoid area. They do not produce any discomfort in the patient for a long time, however it may make itself evident by the patient's regurgitation of the polyp, producing asphyxia or, more frequently, dysphagia. The case of a 58 year old male patient is presented herein, with a 9 month record of dysphagia, weight loss and intermittent melena. The barium x-ray showed a distended esophagus, with a tumor running from the upper esophageal sphincter to the cardia. The endoscopy confirmed the presence of a pediculated tumor, implanted in the cervical esophagus. Surgeons suspected the potential malignancy of the tumor and performed a transhiatal esophagectomy. The final pathologic diagnosis was giant fibrovascular esophageal polyp.

RESUMO

Dieulafoy lesion is an unsual source of upper astrointestinal bleeding with a frequency ranging from 0.3 to 6.7% of the reported literature, although at present it is more frequently diagnosed. It usually begins abruptly with massive bleeding and hemodynamic involvement. The higher prevalence is found in older people and because this group of patients is generally affected by other diseases, Dieulafoy lesion may be life threatening. A thick arterial blood vessel flows through the mucosa and submucosa and in more than 75% of cases the lesion is mostly found within 6 cm of the cardia. The severity of bleeding and the site of the lesion render the diagnosis sometimes difficult, more than one endoscopic exam is often required.There are different types of endoscopic treatment but combined methods seem to be the consense, epinephrine injection followed by thermal coagulation, rubber banding, or recently, hemoclips is being reported. The injection of sclerosing agents is also useful as has been published in later reports. The treatment must be aggressive to obliterate the bleeding vessel. The rate of complications reported with endoscopic approach, mainly perforation, is very low.Initial hemostasis is accomplished in 82% to 96% of cases and a complete one is achieved in 60% to 91% of the events. Recurrence can be treated in the same way as the first episode, but frequently massive bleeding or failure of an initial attempt to obliterate the vessel makes surgery mandatory. The prevalence rate of surgical treatment is between 2% to 36%, being local excision a better approach than the simple suture of the lesion. Before endoscopic age, the mortality rate was as high as 80% but it has been reduced, values range now from 0% to 22%. Long term follow - up after an initial successful endoscopic procedure has decreased the incidence of recurrency of the bleeding episode, being at present as low as 0% to 4.7%

RESUMO

Gastrointestinal bleeding in childhood is an uncommon problem, althought when it happens it maybe an emergency. Upper bleeding predominates, and when we consider lower bleeding, the principal cause are polyps. Recent evidence points out that polyps are responsible for bleeding in 77% of cases.We decided to study the clinical course, histologic characteristics and treatment in children with lower gastrointestinal bleeding. This investigation was held at Edgardo Rebagliati National Hospital during 1990 to 1996. Inclusion criteria were: younger than 14 years, gastrointestinal bleeding, and colonoscopy exam.100 colonoscopies were done in 74 children. Polyps were the cause for gastrointestinal bleeding in 71.6% of cases. In 14 children more than one colonoscopy was done. More than one polyp in 16 children were found. Ulcerative colitis was diagnosed in two cases, and intestinal tuberculosis in other two cases. Average age was 8.8 years, and 100% presented rectorragia and anemia.Polyps were located principally in rectum and sigmoid. Polipectomy was done in 94.34% of the cases, and it was technically succesful. We had only one complication (snare wire was trapped) but with no morbidity.Histological examination demonstrated that juvenile polyp was the most frequent type (56.66%), followed by tubular adenoma (11.32%), and Peutz-Jegher polyp in 3.77%. Treatment was polipectomy in all cases. Eleven procedures were done in the surgical room, and 19 in the endoscopy unit, with no complications in any of the cases.CONCLUSION: In children the main cause for lower gastrointestinal bleeding are polyps. All cases present with rectorragia or anemia, and juvenile polyps are the most frequent type. Colonoscopy is a safe method for diagnosis and treatment, which can be done in the endoscopy unit with mild sedation and with an anesthesist or pediatrician as assistants.
