RESUMEN
Intestinal malrotation is a congenital anomaly of intestinal rotation and fixation, diagnosed infrequently in adulthood. We report the presence of intestinal malrotation in a previously asymptomatic adult patient with changes in bowel habit in the last 6 months after a colonoscopy is performed with evidence of a polyp in the cecum, after resection presenting acute abdominal pain in the left iliac fossa that allows imaging to confirm the diagnostic.

La morbilidad y alteración de la calidad de vida asociadas a la resección anterior del recto y amputación abdominoperineal determinaron un gran interés en el desarrollo del abordaje transanal. En los últimos años se ha visto un marcado desarrollo tecnológico en los dispositivos disponible para este abordaje. La cirugía por vía transanal ofrece ventajas en cuanto a sus resultados y complicaciones cuando se la compara a la cirugía por vía abdominal. La cirugía transanal mini-invasiva surge como una alternativa de abordaje videoendoscópico del recto. La resección local por cirugía endoscópica para los pólipos grandes de recto se ha convertido en un nuevo estándar de tratamiento en la mayoría de los centros, obteniendo piezas no fragmentadas con una alta tasa de márgenes negativos. En el presente estudio realizamos una revisión sobre la aplicación de TAMIS (TransAnal Minimally Invasive Surgery) al tratamiento de los pólipos de recto. (AU)
A great interest has developed in implementing trans anal minimally invasive surgery for the treatment of rectal adenomas and early rectal tumors. It present advantages when compare to radical surgery and peace meal endoscopic resections. TAMIS delivers non-fragmented specimens with clear resection margin in the majority of the cases. Such good technical results are mirrored with a low recurrence rate when evaluating rectal adenomas. This is a review of the application of TAMIS for the treatment of rectal adenomas. (AU)

INTRODUCTION AND AIMS: Peutz-Jeghers syndrome is an autosomal dominant inherited pathology characterized by gastrointestinal hamartomatous polyps, predominantly in the small bowel, and pigmented mucocutaneous lesions. Guidelines suggest polypectomy with a balloon-assisted enteroscope when polyps are larger than 10mm. Complications in adults can be as high as 6.8%, but there is little information on pediatric populations. Our aim was to describe the safety and efficacy of polypectomy in a group of pediatric patients with Peutz-Jeghers syndrome using balloon-assisted enteroscopy. MATERIALS AND METHODS: A retrospective study was conducted at the Hospital de Especialidades del Centro Médico Nacional Siglo XXI on pediatric patients with Peutz-Jeghers syndrome that required balloon-assisted enteroscopy and polypectomy within the time frame of January 2010 and December 2015. Patients that underwent polypectomy with a push enteroscope were excluded from the study. RESULTS: A total of 35 polypectomies were performed on 4 patients (female/male: 3/1). The mean age of the patients was 13.7 years (range:11-16). Twelve enteroscopies were carried out, 8 of which were anterograde. A single-balloon enteroscope was used in 7 procedures and a double-balloon enteroscope in 5. The mean size of the polyps was 1.6cm (range: 1-4cm). A major complication (acute pancreatitis) presented in only one case (8.3%). No other major complications associated with the procedures were observed. CONCLUSION: Balloon-assisted enteroscopy with polypectomy in children is a safe and effective procedure, with complications similar to those reported in adults.

Introducción: Los pacientes con pólipos colorrectales no pediculados grandes (PCNP-G) han sido tradicionalmente tratados quirúrgicamente. Los avances en la endoscopía terapéutica permiten que la resección endoscópica de estas lesiones pueda ser considerada como una alternativa a la cirugía. Objetivo: Evaluar la eficacia y seguridad de la resección endoscópica en pacientes con PCNP-G. Materiales y métodos: Cohorte prospectiva multicéntrica. Se incluyeron a todos los pacientes referidos para resección endoscópica de PCNP-G entre enero del 2012 y diciembre del 2015, seguidos hasta agosto del 2016. Se obtuvieron las tasas de resecciones exitosas, de recurrencia y de complicaciones. Se analizaron los factores predictivos asociados a resección no exitosa y a recurrencia. Resultados: Se incluyeron 107 pacientes con 115 PCNP-G. La tasa de resección exitosa fue de 92%. Las complicaciones más comunes fueron el sangrado (8,7%) y la perforación (2,6%). La tasa de recurrencia fue de 7%, todas tratadas endoscópicamente con éxito. Los factores predictivos de resección no exitosa fueron una medida >50 mm de la lesión resecada y la presencia de fibrosis; y el único factor predictivo de recurrencia fue una medida >50 mm del pólipo resecado. Conclusiones: La resección endoscópica de los PCNP-G es altamente eficaz y segura
Introduction: Patients with large non-pedunculated colorectal polyps (L-NPCP) have been traditionally treated with surgery. Advances in therapeutic endoscopy allow endoscopic resection of these lesions and can be considered as an alternative to surgery. Objective: To evaluate the efficacy and safety of endoscopic resection in patients with L-NPCP. Methods: A prospective multicentric cohort. All patients referred for endoscopic resection with L-NPCP between January 2012 and December 2015, followed until August 2016, were included. Rates of successful resection, recurrence and complications were obtained. Predictive factors associated with unsuccessful resection and recurrence were analyzed. Results: 115 L-NPCP in 107 patients were included. The rate of successful resection was 92%. The most common complications were bleeding (8.7%) and perforation (2.6%). The recurrence rate was 7%, all successfully treated with a new endoscopic session. Predictors of unsuccessful resection were a measure >50 mm of the lesion and the presence of fibrosis; and the only predictor of recurrence was a size of the polyp resected >50 mm. Conclusions: Endoscopic resection of L-NPCP is very efficacious and safe

INTRODUCTION: Colorectal polyps are structures that project from the surface of the mucosal layer of the large intestine. They are classified as neoplastic or non-neoplastic. Early detection of pre-neoplastic lesions is important for preventing colorectal cancer. These can be resected so as to decrease the morbidity and mortality rates. Colonoscopy is the gold-standard procedure for diagnosing and resecting precursor lesions. OBJECTIVE: To evaluate the epidemiological, endoscopic and histological aspects of endoscopic resection of lesions of the colon and rectum at a training center. MATERIALS AND METHOD: A search was conducted in the database of our institution covering the period from January 2011 to July 2014. Cases that underwent endoscopic resection of polyps and/or colorectal lesions were selection. The following variables were defined: general data on the patients (age, gender and indication from the examination) and data on the polypoid lesion (number, histological type and topographic distribution). RESULTS: 678 lesions were identified in 456 examinations. Regarding sex, 242 (53.1%) were female and 214 (46.9%) were male. The mean age was 64.54 years, with extremes of 5 and 94 years. The most frequent locations were the rectum (21%) and sigmoid (20%). Histologically, 34.7% were hyperplastic polyps and 58.9% were adenomatous polyps, of which 74.1% were tubular, 10.6% tubulovillous, 2% villous and 13% indeterminate; and 1.7% were adenocarcinomas. In 65.4% of the cases, the examination showed that only one polyps was present, while 34.6% had two or more lesions. CONCLUSION: In our clinic, with a mean of 250 examinations/month, the parameters evaluated were compatible with the results reported in the literature.

BACKGROUND: Inflammatory fibroid polyp (IFP) is a very rare benign condition in children that can occur throughout the gastrointestinal tract. It is characterized as a polypoid lesion originating in the submucosa, composed of connective tissue and eosinophilic infiltrate. It is most common in the stomach and in adults between the fifth and seventh decades of life. Its occurrence is unusual in the duodenum. CASE SUMMARY: One case of duodenal IFP was described and the literature is reviewed with emphasis on the clinical and pathological features of IFP in children. A case of an IFP in the duodenum of a 13-year-old girl, who presented with abdominal pain, weight loss, vomiting, and constipation. The patient underwent exploratory laparotomy; a stenosing tumor of the third duodenal portion was found. The affected segment was resected and an end-to-end anastomosis between the duodenum and jejunum segment was performed. Immunohistochemically, actin and CD34 were positive, Ki67 was positive in <1% of cells, and the proteins CD117 and S100 were negative. CONCLUSION: To our best of our knowledge, this is the fourth report of IFP in adolescents, the first in a female's duodenum.

Abstract Background Inflammatory cloacogenic polyp is a very rare kind of benign polyp which occurs in the anal transitional zone and lower rectum. These polyps arise in association with various conditions (e.g., internal hemorrhoids, diverticulosis, colorectal tumors, and Crohn's disease) in which mucosal injury is the underlying pathogenic mechanism. Case report A 24-year-old male patient applied to emergency department with bloody defecation for a month. A polyp that is 1.5 cm in size had been observed at rectum and anal verge junction during colonoscopy, pathological diagnosis was inflammatory cloacogenic polyp. Thereupon, colonoscopic polypectomy was performed as the malignant transformation possibility. Conclusion Polyps of the anorectal junction with inflammatory appearance might be inflammatory cloacogenic polyps with malignant transformation potential that must be treated by endoscopic removal or surgery and followed up routinely with colonoscopic surveillance.
Resumo Experiência Pólipos cloacogênicos inflamatórios constituem um tipo muito raro de pólipo benigno, com ocorrência na zona de transição anal e reto baixo. Esses pólipos surgem em associação com diversos distúrbios (p. ex., hemorroidas internas, diverticulose, tumores colorretais, e doença de Crohn) nos quais a lesão à mucosa é o mecanismo patogênico subjacente. Relato de caso Paciente, gênero masculino, 24 anos, compareceu ao serviço de emergência com defecação sanguinolenta com duração de um mês. Durante a colonoscopia, foi observado um pólipo medindo 1,5 cm de diâmetro no reto e na junção da borda anal; foi estabelecido um diagnóstico patológico de pólipo cloacogênico inflamatório. Subsequentemente, foi realizada polipectomia colonoscópica, diante do potencial de transformação maligna. Conclusão Pólipos da junção anorretal com aspecto inflamatório podem ser pólipos cloacogênicos inflamatórios com potencial para transformação maligna, devendo ser tratados por remoção endoscópica ou cirúrgica e monitorados periodicamente com vigilância colonoscópica.

BACKGROUND: Inflammatory fibroid polyp (lFP) is a rare, benign, and solitary neoplasm predominantly located in the gastric antrum and small bowel. Its clinical symptoms are heterogeneous and essentially depend on the location and size of the tumor. Definitive diagnosis is made through histopathology and this pathology has excellent long-term prognosis. AIM: To identify the cases of IFP seen at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán over a 10-year period. METHODS: A retrospective, cross-sectional, descriptive, and observational study was conducted that included patients with histopathologic diagnosis of IFP within the time frame of January 2001 and December 2011. RESULTS: Six cases were found and 5/6 (83.3%) of them were women. The median age was 41 years (minimum-maximum range of 19-56 years). The most frequent symptoms were weight loss (n=3), fever (n=2), nausea (n=2), and vomiting (n=2). Three patients presented with iron deficiency anemia and 2 cases with intussusception. The IFPs were located at the following sites: esophagus (n=1), stomach (n=2), small bowel (n=2), and colon (n=1). Treatment was surgical in 5/6 (83.3%) of the patients. CONCLUSIONS: IFPs are extremely rare in our population. They usually present with weight loss and iron deficiency anemia and are more frequently located in the stomach and small bowel. This is the largest reported IFP case series in a Mexican population.

Peutz-Jeghers syndrome (PJS) is an infrequent autosomal dominant inherited disorder, characterized by hamartomatous polyps associated to mucocutaneous pigmentation. The main problem in the management of PJS are the small intestine polyps that may cause intussusception with secondary intestinal obstruction and bleeding. Enteroscopic polypectomy is the preferred therapy for resection of small intestine polyps, reducing the number of emergency laparotomies and intestinal resection. Follow-up of gastrointestinal polyps is required. The best combination of diagnostic methods in the small intestine is capsule endoscopy and magnetic resonance enteroclysis. Long-term scheduled screening for neoplasies is essential. All first degree relatives must be evaluated. Although PJS incidence is low, it is important for the clinicians to be able to identify this condition in order to prevent complications and mortality. This article analyzes the management of three PJS case studies with small intestine polyps treated with resection using double balloon enteroscopy (DBE).
El síndrome de Peutz-Jeghers (SPJ) es una entidad hereditaria autosómica dominante de presentación inusual, caracterizado por poliposis hamartomatosa asociada con pigmentación mucocutánea. El principal problema en el manejo del SPJ son los pólipos en el intestino delgado (ID), los cuales pueden causar intususcepción con obstrucción intestinal secundaria y hemorragia. La polipectomía mediante enteroscopia, es la terapia de elección para la resección de pólipos en el ID, logrando disminuir el número de laparotomías de urgencia y resección intestinal. El seguimiento de pólipos gastrointestinales es necesario. La mejor combinación de métodos diagnósticos en ID es la cápsula endoscópica y la enteroclisis por resonancia magnética (RM). El screening de neoplasias programado a largo plazo es indispensable. Es necesario evaluar a todos los familiares de primer grado. Aunque la incidencia de SPJ es baja, es importante para los clínicos reconocer ésta enfermedad para prevenir sus complicaciones y mortalidad. En este artículo analizaremos el manejo de tres casos clínicos con SPJ con pólipos en ID tratados con resección mediante enteroscopia doble balón (EDB).

A case of a 84 year-old woman with a history of colonoscopy performed in May 2008, where a 5 mm polyp was detected from the hepatic flexure. It was removed by biopsy and histology showed a tubular adenoma with low-grade dysplasia. In May 2011, the patient consulted due to mild to moderate pain in both hypochondria of 6 months of duration accompanied by bloating and belching. A control colonoscopy was indicated, which was held in June 2011, and showed a 2 cm polyp in ascending colon, this was resected with polypectomy snare. In the vicinity there was a 3-mm polyp that was removed with biopsy forceps. Histological examination showed in the bigger lesion a moderately differentiated grade 2 invasive tubular adenocarcinoma, with superficial and focal invasion of the submucosa, developed in adenoma with free surgical margin (1.7 mm), no vascular, lymphatic invasion or tumor budding were found. The smaller lesion was reported as tubular adenoma with low grade dysplasia. Colorectal cancer epidemiology, indications for controls after colonoscopic polypectomy of adenomas, especially those at high risk, histopathological risk factors for adenocarcinomas developed in adenomas and the need to monitor these patients annually with occult blood test stool are discussed between the control colonoscopies indicated.
Se presenta el caso de una mujer de 84 años, con antecedentes de colonoscopia efectuada en mayo de 2008 donde se le detectó un pólipo de 5 mm del ángulo hepático del colon, el que fue extraído por biopsia y cuyo estudio histológico demostró un adenoma tubular con displasia de bajo grado. En mayo de 2011, consulta por dolor leve a moderado en ambos hipocondrios de 6 meses de evolución acompañados de meteorismo y eructos. Se indicó ileocolonoscopia, la que se realizó en junio de 2011 y demostró un pólipo del colon ascendente de 2 cm, que fue resecado con asa de polipectomía; y cercano a éste, un pólipo de 3 mm que se extirpó con pinza biopsia. El examen histológico informó adenoma tubular con displasia moderada en la lesión de menor tamaño y adenocarcinoma tubular invasor moderadamente diferenciado grado 2 de Broders, con invasión focal superficial de la submucosa, desarrollado en adenoma. Límites quirúrgicos libres de lesión, sin invasión vascular sanguínea, linfática ni budding tumoral con límite quirúrgico profundo a 1,7 mm de la lesión. Se comentan la epidemiología del cáncer rectocolónico, la indicación de los controles colonoscópicos luego de la polipectomía de los adenomas, en especial de aquellos de alto riesgo, los factores de riesgo anatomopatológicos de carcinomas desarrollados en adenomas, y la necesidad de controlar anualmente a estos pacientes con colonoscopias de vigilancia.

Distribución por sexo: 68% hombres y 32% mujeres. El 61% de los pacientes tenía 1 pólipo, el 22% 2, el 12% 3, el 4% 4 y el 1% 6 pólipos. El 88% eran menores a 10 mm, y el 22% mayor a 10 mm. El 50,9% eran adenomas tubulares Viena 3, el 32% eran pólipos hiperplásicos, el 5,45% adenomas serratos, el 3,63% adenomas tubulares con displasia de alto grado Viena 4, y el 0,9% adenomas vellosos Viena 3. De los pólipos menores a 10 mm, 2 tenían displasia de alto grado, 5 eran adenomas tubulares Viena 3 y 1 pólipo menor a 10 mm era un adenoma velloso; la totalidad de los adenomas serratos tenían un diámetro menor a 10 mm. Conclusión: Los resultados encontrados en nuestra experiencia coinciden con los publicados en la bibliografía internacional. Al prevenir la progresión de la secuencia adenoma-carcinoma y proporcionar un tratamiento temprano de lesiones preneoplásicas asintomáticas la pesquisa disminuye la probabilidad de padecer cáncer colorrectal.
Objectives: To demonstrate and to evaluate a colorectal cancer screening program in a captive population with low risk. We determine the incidence of polyps, and describe their morphological and pathological features. Methods: A retrospective analysis of 1246 colonoscopic procedures performed during the period of 05/2009 - 05/2010. We evaluate the incidence of polyps, number, shape, size and histology. Results: Polyps were found and resected in 100 patients (25% of all screening colonoscopies). 68% of the patients were males, 61% of our sample had I polyps, 22% had 2, 12% had 3, 45 had 4 polyps, and 1% 6 lesions. 50,9% of the resected polyps were tubulous adenomas (Vienna 3), 32% were hyperplastic polyps. 5,45% serrated adenomas and 3,63% tubulous adenomas with high grade dysplasia. Conclusions: Our results do not differ from literature. Screening reduces probability to develop colorectal cancer, as it disrupts the adenoma-carcinoma sequence, as well as representing an early treatment of asymptomatic neoplastic lesions.

BACKGROUND: Intussusception in an adult must make us suspect the presence of a tumor (benign or potentially dangerous) as the most frequent cause. Accurate diagnosis is of great importance in order to provide appropriate treatment and improve patient prognosis. CLINICAL CASE: We report the case of a 42-year-old male with abdominal pain. We performed a CT and found a small bowel intussusception. Definitive diagnosis according to the surgical specimen was inflammatory fibroid polyp (Vanek's polyp). CONCLUSIONS: Vanek's polyp is a benign lesion that occurs most frequently in the stomach and secondarily in the small bowel. Generally, it is uncommon, and its etiology is not completely known. Accurate diagnosis is done with immunohistochemistry. Because of the consequences that depend on the size and location of the lesion, it may be considered a malignant lesion. Treatment is resection.
