Tumor neuroectodérmico maligno del tracto gastrointestinal: a propósito de un caso / Malignant neuroectodermal tumor of the gastrointestinal tract: case report

El tumor neuroectodérmico maligno del tracto gastrointestinal es una neoplasia rara con pocos casos reportados en la literatura, especialmente en América Latina. Descrito por primera vez en 2003, se trata de una entidad sin tratamiento estandarizado y de pobre pronóstico. Se presenta el caso de una paciente de 22 años de edad que acude a la consulta por dolor abdominal, anemia y masa abdominal palpable. Luego de estudios pertinentes se decide la conducta resectiva y el posterior tratamiento oncológico. (AU)

Malignant gastrointestinal neuroectodermal tumor (GNET), formerly known as clear cell sarcoma of the gastrointestinal tract, is an extremely rare tumor of mesenchymal origin, which presents great microscopic and molecular similarity to clear cell sarcoma found in other parts of the body, such as tendons and aponeurosis. It is characterized by its rapid evolution, high recurrence rate and frequent diagnosis as metastatic disease.1,2 (AU)

Ghost ileostomy release down: our initial experience

Background: Many publications describe the advantages of the creation of ghost ileostomy (GI) to prevent the need for formal covering ileostomy in more than 80% of carcinoma rectum patients. However, none of the papers describes exactly how to ultimately remove the GI in these 80% of patients in whom it doesn't need formal maturation. Aim: To describe and evaluate the ghost ileostomy release down (GIRD) technique in terms of feasibility, complications, hospital stay, procedure time etc. in patients with low anterior resection/ultra-low anterior resection (LAR/uLAR) with GI for carcinoma rectum. Method: The present was a prospective cohort study of patients with restorative colorectal resections with GI for carcinoma rectum, Postoperatively the patients were studied with respect to ease and feasibility of the release down of GI and its complications. The data was collected, analyzed and inference drawn. Results: A total of 26 patients needed the GIRD and were included in the final statistical analysis of the study. The procedure was done between 7th to 16th postoperative days (POD) and was successful in all patients without the need of any additional surgical procedure. None of the patients required any local anesthetic injection or any extra analgesics. The average time taken for procedure was 5-minutes and none of the patients had any significant difficulty in GI release. There were no immediate postprocedure complications. Conclusion: The GIRD technique is a simple, safe, and quick procedure done around the 10th POD that can easily be performed by the bedside of patient without the need of any anesthesia or additional analgesics.

Resultados quirúrgicos a corto y mediano plazo por enfermedad de Crohn ileocecal / Short and medium term results of the surgical management of ileocecal Crohn's disease

BACKGROUND: The treatment of Crohn's disease (CD) is based on medical therapy and surgery is reserved for failure of medical management or complications. AIM: To evaluate endoscopic, clinical, and surgical recurrence of CD after surgery. MATERIAL AND METHODS: In a prospectively maintained database, consecutive patients older than 15 years subjected to an ileocecal resection for ileocolic disease from January 2011 to April 2021, were identified. The diagnosis of CD was confirmed with the pathologic report. Patients with less than one year of follow-up were excluded. Information was obtained retrospectively from the database and clinical records. RESULTS: Fourteen patients were identified. The mean age at the time of surgery was 38 years. Surgery was performed at a median of 41.5 months (0-300) after the diagnosis of CD, nine elective and five emergency procedures. In five patients there were four major and two minor postoperative complications, with no anastomotic leakage. Six patients had endoscopic recurrence and seven had clinical recurrence (50%) at a mean of 15 months, one of whom required a second operation. There was no mortality. CONCLUSIONS: After the surgical treatment of CD, the clinical and endoscopic recurrence rate continues to be high.

Evisceración intestinal transvaginal incarcerada con perforación intestinal después de una colporrafia con malla. Reporte de un caso / Incarcerated transvaginal bowel evisceration with intestinal perforation after a mesh colporraphy. A case report

Introducción. La evisceración intestinal transvaginal es consecuencia, en la gran mayoría de casos, de dehiscencia del muñón vaginal posterior a histerectomía en pacientes postmenopáusicas. A través de la dehiscencia vaginal se produce la salida del contenido abdominopélvico, que puede presentarse como una evisceración simple, incarceración, obstrucción, estrangulamiento y perforación de un asa intestinal. Caso clínico. Mujer de 78 años, con antecedente inmediato de colpocleisis y colporrafia con malla de polipropileno por prolapso vaginal, que presentó dehiscencia del muñón vaginal debido a rechazo de la malla, que condicionó la solución de continuidad de la pared vaginal, con prolapso, incarceración, obstrucción y perforación de íleon. Con el diagnóstico de evisceración intestinal transvaginal incarcerada con perforación intestinal se llevó a tratamiento quirúrgico, con abordaje inicial por vía vaginal para liberar el asa intestinal, luego por laparotomía se realizó resección y anastomosis de íleon, sacrocolpopexia con malla y plastia de Douglas. Presentó buena evolución postoperatoria.Conclusión. La evisceración intestinal transvaginal con perforación intestinal es una entidad de muy rara presentación. El órgano más frecuentemente comprometido es el intestino delgado, especialmente el íleon. Puede complicarse con incarceración, obstrucción intestinal, isquemia y perforación. El manejo quirúrgico involucra resección intestinal, cuando hay signos de necrosis, con reparación y fijación del muñón vaginal.

Introduction. Transvaginal intestinal evisceration is a consequence, in the vast majority of cases, of dehiscence of the vaginal stump after hysterectomy in postmenopausal patients. Through vaginal dehiscence, the exit of the abdominopelvic content occurs, which can present as a simple evisceration, incarceration, obstruction, strangulation and perforation of an intestinal loop. Clinical case. A 78-year-old woman with an immediate history of colpocleisis and polypropylene mesh colporrhaphy due to vaginal prolapse, presents dehiscence of the vaginal stump caused by rejection of the mesh that conditioned the solution of continuity of the vaginal wall, prolapse, incarceration, obstruction and perforation of the ileum. Surgical treatment was performed with the diagnosis of incarcerated transvaginal intestinal evisceration with intestinal perforation. The initial approach was to free the intestinal loop vaginally, followed by laparotomy, ileal resection and anastomosis, mesh sacrocolpopexy, and Douglas plasty were performed. He presented good postoperative evolution.Conclussion. Transvaginal intestinal evisceration with intestinal perforation is a very rare entity. The most common organ involved is the small intestine, especially the ileum. It can be complicated by incarceration, intestinal obstruction, ischemia, and perforation. Surgical management involves intestinal resection, when there are signs of necrosis, with repair and fixation of the vaginal stump.

Íleo biliar: reporte de casos / GALLSTONE ILEUS: CASES REPORT

El íleo biliar se define como una obstrucción intestinal mecánica secundaria a la presencia de un cálculo biliar. Menos del 1% de los casos de obstrucción intestinal se derivan de esta etiología. La causa más frecuente es la impactación del cálculo en el íleon, tras su paso por una fístula bilioentérica. Es una complicación rara y potencialmente grave de la colelitiasis. Esta patología se presenta más en adultos mayores, la edad promedio en la que se presenta es entre los 60 y 84 años, afectando principalmente al sexo femenino, atribuido a la mayor frecuencia de patología biliar en dicho sexo. Presenta una alta morbimortalidad, principalmente por la dificultad y la demora diagnóstica.

Gallstone ileus is defined as a mechanical intestinal obstruction secondary to the presence of a gallstone. Less than 1% of cases of intestinal obstruction are derived from this etiology. Te most frequent cause is the impaction of the stone in the ileum, after passing through a bilioenteric fistula. It is a rare and potentially serious complication of cholelithiasis. Tis pathology occurs more in the elderly, the average age at which it occurs is between 60 and 84 years, mainly affecting the female sex, attributed to the higher frequency of biliary pathology in said sex. It presents a high morbidity and mortality, mainly due to the difficulty and the diagnostic delay

Risk factors for anastomotic leakage following total or subtotal colectomy

Introduction: A higher rate of anastomotic leakage (AL) is reported after ileosigmoid anastomosis (ISA) or ileorectal anastomosis (IRA) in total or subtotal colectomy (TSC) compared with colonic or colorectal anastomosis. Themain aimof the present studywas to assess potential risk factors for AL after ISA or IRA and to investigate determinants of morbidity. Methods: We identified 180 consecutive patients in a prospective referral, single center database, in which 83 of the patients underwent TSC with ISA or IRA. Data regarding the clinical characteristics, surgical treatment, and outcome were assessed to determine their association with the cumulative incidence of AL and surgical morbidity. Results: Ileosigmoid anastomosis was performed in 51 of the patients (61.5%) and IRA in 32 patients (38.6%). The cumulative incidence of ALwas 15.6% (13 of 83 patients). A higher AL rate was found in patients under 50 years-old (p=0.038), in the electivelaparoscopic approach subgroup (p=0.049), and patients in the inflammatory bowel disease (IBD) subgroup (p=0.009). Furthermore, 14 patients (16.9%) had morbidity classified as Clavien-Dindo ≥ IIIA. Discussion: A relatively high incidence of AL after TSC was observed in a relatively safe surgical procedure. Our findings suggest that the risk of AL may be higher in IBD patients. According to our results, identifying risk factors prior to surgerymay improve short-term outcomes. (AU)

The value of terminal lleum intubation during colonoscopy

Abstract It is uncertain whether terminal ileum intubation should be performed routinely during colonoscopy, as there is uncertainty regarding its diagnostic value. The aim of the present study is to assess the diagnostic yield of terminal ileum intubation during colonoscopy according to indications for colonoscopy. This is a cross-sectional study in which the results of 294 total colonoscopy procedures were reviewed; ileal intubation was performed in 269 (91.49%) patients. The indications for colonoscopy, the results of ileoscopy, and the histopathological results of ileal biopsies were evaluated. A total of 54 (20%) out of 269 patients who had successful intubation into the terminal ileumshowed macroscopic abnormalities on the terminal ileum. Biopsies were positive in 4 out of 54 (7.4%); all were of Crohn disease. Two were erosions (9.5%.) and 2 were ulcers (18.8%). The two erosions were presented as abdominal pain, abdominal pain and alternating bowel motion. Those with ulcers were presented with diarrhea and perianal disease. Conclusions Considering the low diagnostic yield of ileal intubation during colonoscopy, the decision to performileoscopy or not during colonoscopy needs to bemade on a case-by-case basis. However, routine ileal intubation, brief attempts should be considered despite low diagnostic yield. (AU)

Effect of Suanzaoren Decoction on molecular levels of bile acids in serum, liver, and ileum of insomnia mice / 中国中药杂志

To explore the mechanism of Suanzaoren Decoction in the treatment of insomnia from endogenous bile acid regulation, the present study investigated the hepatoprotective effect of Suanzaoren Decoction and the molecular changes of bile acids in the serum, liver, and ileum of insomnia model mice and Suanzaoren Decoction treated mice. The insomnia model in mice was established by the sleep deprivation method. After Suanzaoren Decoction(48.96 mg·kg~(-1)·d~(-1)) intervention by gavage for 7 days, the related indicators, such as water consumption, food intake, body weight, aspartate aminotransferase(AST), alanine transaminase(ALT), and total bile acid(TBA) were detected, and the pathological changes of the liver and ileum were observed. The molecular levels and distribution of 23 bile acids in the serum, liver, and ileum were analyzed by UPLC-MS/MS combined with principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA). The results showed that Suanzaoren Decoction could improve the decreased water consumption and food intake, weight loss, and increased AST and ALT in the model group, and effectively reverse the injury and inflammation in the liver and ileum. The bile acids in the liver of the insomnia model mice were in the stage of decompensation, and the bile acids in the serum, liver, and ileum of the mice decreased or increased. Suanzaoren Decoction could regulate the anomaly of some bile acids back to normal. Seven bile acids including glycoursodeoxycholic acid(GUDCA), glycodesoxycholic acid(GDCA), tauro-α-MCA(T-α-MCA), α-MCA, taurodeoxycholate(TDCA), T-β-MCA, and LCA were screened out as the main discriminant components by PLS-DA. It is concluded that Suanzaoren Decoction possesses the hepatoprotective effect and bile acids could serve as the biochemical indicators to evaluate the drug efficacy in the treatment of abnormal liver functions caused by insomnia. The mechanism of Suanzao-ren Decoction in soothing the liver, resolving depression, tranquilizing the mind, and improving sleep may be related to the molecular regulation of bile acid signals.

Ileoscopia: quando a avaliação ileal não é mandatória durante a colonoscopia / Ileoscopy: when ileal evaluation is not mandatory during colonoscopy

ABSTRACT BACKGROUND: Ileitis is defined as ileal inflammation, with several etiologies, including inflammatory bowel disease (IBD), and can be evaluated during the colonoscopy exam, but its mandatory evaluation is discussed, because of few diagnosis and procedure time. OBJECTIVE: This study aims to evaluate the correlation of colonoscopic ileitis with the clinical presentation, in order to identify the cases where ileal examination is mandatory. METHODS: A retrospective, cross-sectional study was conducted between 2013 and 2017. The examination report, indications for colonoscopy, and medical records were evaluated in order to identify whether the colonoscopic findings were clinically significant. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age, those with previous intestinal resections, and repeated examinations of the same patient in the study period were excluded. The estimated association measure was the odds ratio with 95% confidence intervals. P-values <0.05 indicated statistical significance. RESULTS: A total of 3382 cases were included. Among these participants, 64.5% were females and the average age was 56.9±13.1 years (18-89 years). Ileal alterations were observed in 5.3% of the patients, with 2.69% being clinically significant between all patients, and 0.96% excluding those with IBD. There was a positive correlation between the ileitis findings and IBD control examinations and a negative correlation in screening and change in bowel habit indications. Among the indications with ileitis clinically significant, IBD control still had a positive correlation, 'diarrhea' and 'others' did not show a statistical significance, and all other indications presented a negative correlation for ileal assessment. CONCLUSION: Ileal evaluation in only mandatory in IBD control. When the main colonoscopy objective is detecting colonic neoplasms, ileoscopy is unnecessary.

RESUMO CONTEXTO: Ileíte é definida como inflamação ileal, com diversas etiologias, incluindo doença inflamatória intestinal (DII), e pode ser avaliada durante o exame de colonoscopia, mas sua avaliação obrigatória é discutida, devido aos poucos diagnósticos e tempo de procedimento. OBJETIVO: O objetivo deste estudo é avaliar a correlação da ileíte colonoscópica com a apresentação clínica, a fim de identificar os casos em que o exame ileal é obrigatório. MÉTODOS: Foi realizado um estudo transversal retrospectivo entre 2013 e 2017. O laudo do exame, as indicações para colonoscopia e os prontuários médicos foram avaliados para identificar se os achados colonoscópicos eram clinicamente significativos. Pacientes maiores de 18 anos submetidos à ileoscopia foram incluídos, enquanto pacientes menores de 18 anos, aqueles com ressecções intestinais prévias e exames repetidos do mesmo paciente no período de estudo foram excluídos. A medida de associação estimada foi o odds ratio com intervalos de confiança de 95%. Valores de P <0,05 indicaram significância estatística. RESULTADOS: Foram incluídos 3382 casos. Desses, 64,5% eram mulheres e a média de idade foi de 56,9±13,1 anos (18-89 anos). Alterações ileais foram observadas em 5,3% dos pacientes, sendo 2,69% clinicamente significativos entre todos os pacientes e 0,96% excluindo aqueles com DII. Houve uma correlação positiva entre os achados de ileíte e exames de controle de DII e uma correlação negativa no rastreamento e alteração de hábito intestinal. Entre as indicações com ileíte clinicamente significativa, o controle de DII ainda teve uma correlação positiva, 'diarreia' e 'outros' não apresentaram significância estatística, e todas as outras indicações apresentaram correlação negativa para avaliação ileal. CONCLUSÃO: A avaliação ileal é obrigatória apenas no controle de DII. Quando o objetivo principal da colonoscopia é detectar neoplasias colônicas, a ileoscopia é desnecessária.

Functional results of hautmann neobladder with chimney modification and wallace ureteroileal anastomosis: initial experience with 22 patients

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

Nutritive evaluation, metabolisable energy and digestible amino acid contents of different indigenous feedstuff for Nile tilapia (Oreochromis niloticus) / Avaliação nutricional, energia metabolizável e conteúdo de aminoácidos digestíveis de diferentes alimentos indígenas para tilápia do Nilo (Oreochromis niloticus)

Abstract Three trials were executed to examine the nutritive profile, metabolisable energy and digestible amino acid (AA) contents of four indigenous feed ingredients including wheat (W), wheat middling (WM), canola meal (CM) and rapeseed meal (RSM) in Nile tilapia. Three samples of each test ingredient were collected from three different locations of Multan (MUL) and Sukkar (SKR), of Pakistan. The collected three samples were pooled thereafter to make a homogenous/ representative sample of each test ingredient from a particular study site. Nutrients composition, AA and energy digestibility of these indigenous ingredients were evaluated by using laboratory analyses and fish studies. Proximate analysis indicated variations in some of the nutrients due to location (p < 0.05). Differences were also observed in some AA including arginine, lysine, serine, cysteine, glutamic and aspartic acids, histidine, valine and glycine contents of these ingredients (p < 0.05). Digestibility of leucine, glycine and glutamic acid was higher (p < 0.05) in RSM from MUL. Among W samples from MUL, AA digestibility for lysine, threonine, and aspartic acid was higher (p < 0.05). Crude protein, arginine, alanine, serine, and aspartic acid had higher digestibility (p < 0.05), whereas digestibility was lower (p < 0.05) for threonine, valine and tyrosine in RSM from MUL. Metaboliseable energy contents did not differ among W, WM, CM and RSM regarding their origin (p > 0.05). The results indicated that nutritional profiles and their digestibility indices vary with the location for Nile tilapia.

Resumo Três experimentos foram executados para examinar o perfil nutritivo, a energia metabolizável e o conteúdo de aminoácidos digestíveis (AA) de quatro ingredientes alimentícios, incluindo trigo (W), farelo de trigo (WM), farelo de canola (CM) e farelo de colza (RSM) em tilápia do Nilo. Três amostras de cada ingrediente do teste foram coletadas de dois locais diferentes (Multan (MUL) e Sukkar (SKR), do Paquistão) e assim agrupadas. A composição nutricional, AA e digestibilidade energética desses ingredientes indígenas foram avaliadas por meio de análises laboratoriais e estudos de peixes. A análise imediata indicou variações (p <0,05) em alguns dos nutrientes devido à localização. Variações (p <0,05) também foram observadas em alguns teores de AA desses ingredientes. A digestibilidade da leucina, glicina e ácido glutâmico foi maior (p <0,05) em RSM de MUL. Entre as amostras de W da MUL, a digestibilidade de AA para Lys, Thr e Asp foi maior (p <0,05). Proteína Crud, arginina, alanina, serina e ácido aspártico apresentaram maior digestibilidade (p <0,05), e menor (p <0,05) para treonina, valina e tirosina em MRS. Nenhuma diferença (p> 0,05) relacionada a energia metabolizável foi observada entre esses ingredientes em relação à sua origem. Os resultados indicaram que os perfis nutricionais e sua digestibilidade variam com a localização.

Tratamento colonoscópico de íleo biliar: relato de um caso / Colonoscopic treatment of gallstone ileus: a case report

O íleo biliar representa de 1 a 4% das causas de obstrução mecânica do trato gastrointestinal, causado por um cálculo de origem biliar quando atinge a luz intestinal através de uma fístula bilioentérica. O seu tratamento normalmente é cirúrgico através da enterolitotomia, com ou sem realização de colecistectomia e correção da fístula bilioentérica no mesmo tempo cirúrgico. Relata-se o caso de um paciente de 78 anos com obstrução intestinal ao nível do íleo terminal. Devido ao risco cirúrgico elevado optou-se pela realização de colonoscopia de urgência, que extraiu um cálculo de 2,1cm, impactado na válvula ileocecal. O paciente evoluiu bem após o procedimento, sendo optado pelo tratamento conservador da vesícula biliar e fístula durante o internamento. Conclui-se que pacientes de alto risco se beneficiam com procedimentos menos invasivos, como os endoscópicos, que além de diagnósticos podem ser terapêuticos

The gallstone ileus represents 1 to 4% of the causes of mechanical obstruction from gastrointestinal tract, caused by a gallstone when it reaches the intestinal lumen through a bilioenteric fistula. The treatment is usually the enterolithotomy, with or without cholecystectomy and correction of the bilioenteric fistula at the same surgical time. We report a case of a patient, 78 years old, with intestinal obstruction at the level of the ileocecal valve. The examination showed abdominal distension and pain, with no signs of peritonitis. Due to the surgical risk, a emergency colonoscopy was performed, which removed a 2.1 cm gallstone impacted into the ileocecal valve. The patient evolved well after the procedure and it was chosen the conservative approach to the gallbladder and fistula during the same hospital stay. We conclude that the high-risk patients could benefit from less invasive treatments, such as endoscopy, which can be diagnoses and therapeutic

Clinical features of 44 patients with small bowel Crohn / 中南大学学报(医学版)

OBJECTIVES@#At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease.@*METHODS@#From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected.@*RESULTS@#A total of 44 patients were small bowel Crohn's disease. Among them, 40 patients were male. The age at diagnosis was (35.8±10.3) years old and disease duration was (35.2±59.5) months. The subtypes included 29(65.9%) of ileum, 7(15.9%) of jejunum, 8(18.2%) of ileum with jejunum. There were 27(61.4%) of stricture behavior, 4(9.1%) of penetrating behavior, and 13(29.5%) of non-stricture and non-penetrating behavior. Endoscopic visible stricture (29/85, 34.1%) was common, followed by longitudinal ulcers (27/85, 31.8%). Non-caseate granulomatous were found in 2 cases (4.5%). The score of Crohn's disease activity index was correlated to hemoglobin, hematocrit, and erythrocyte sedimentation rate (all @*CONCLUSIONS@#Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.

Diagnóstico diferencial de obstrucción del íleon distal en mujeres jóvenes. ¿Cuál es el rol de la enterorresonancia? / Differential diagnosis of distal ileal obstruction in young women What is the role of magnetic resonance enterography?

Resumen La obstrucción intestinal en pacientes jóvenes es poco frecuente. La mayor parte de los casos se presentan en mujeres jóvenes (premenopáusicas) y suelen estar relacionados a enfermedad inflamatoria intestinal tipo enfermedad de Crohn, o endometriosis con compromiso intestinal. En esta serie de casos presentamos tres pacientes mujeres en etapa reproductiva, con síntomas de obstrucción intestinal, quienes tienen patologías y desenlaces diferenciales. En el abordaje inicial de la obstrucción, se realizó enterorresonancia. Hacemos la presentación de casos, discusión y revisión de la literatura del diagnóstico diferencial de la estenosis en íleon distal y del uso de la enterorresonancia en ese escenario.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1327).

Abstract Intestinal obstruction is uncommon in young patients. Most cases present in young (premenopausal) women and tend to be related to inflammatory intestinal disease such as Crohn's disease or endometriosis with intestinal involvement. In this case series we present three female patients of reproductive age with intestinal obstruction symptoms who have differential diseases and outcomes. The initial approach to the obstruction included magnetic resonance enterography. We present the cases, discussion and review of the literature on the differential diagnosis of distal ileal stenosis and the use of magnetic resonance enterography in this scenario.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1327).

Ileal impaction resolution in a horse with colic via a standing right flank laparotomy ˗ case report / [Laparotomia de equino em estação para resolução de compactação de íleo ˗ relato de caso]

This report describes a horse presenting ileal impaction that went through a right flank laparotomy procedure while standing. The decision to use this technique was made under the influence of several factors: the patient exhibited a calm temperament and demonstrated responsiveness to the analgesic treatment for pain control; the abdominal lesion was amenable to correction by a standing right flank approach. Also, the owner reported financial problems. Ileal obstruction was relieved successfully, and the horse recovery was satisfactory. This case highlights that, in specific cases of colic syndrome, the use of surgical procedures in the standing position might be a viable option and promote fast recovery.(AU)

Este relato de caso descreve um equino com compactação de íleo corrigida por laparotomia em estação pelo flanco direito. A decisão dessa abordagem foi influenciada por vários fatores: o paciente exibiu um temperamento calmo e demonstrou responsividade ao tratamento analgésico para controle da dor; a afecção intestinal em questão foi passível de correção pela abordagem pelo flanco direito em estação; e o proprietário relatou limitações financeiras. A desobstrução ileal foi realizada com sucesso e o cavalo apresentou recuperação satisfatória. Este caso destaca que, em casos específicos da síndrome de cólica, o uso de um procedimento em estação pode ser uma abordagem viável e promover uma rápida recuperação.(AU)

Obstrucción mecánica secundaria a íleo biliar / MECHANICAL OBSTRUCTION SECONDARY TO GALLSTONE ILEUS

Gallstone ileus is defined as a mechanical intestinal obstruction secondary to the presence of a gallstone. Less than 1% of cases of intestinal obstruction are derived from this etiology. The most frequent cause is the impaction of the stone in the ileum, after passing through a bilioenteric fistula. It is a rare and potentially serious complication of cholelithiasis. This pathology occurs more in the elderly, the average age at which it occurs is between 60 and 84 years, mainly affecting the female sex, attributed to the higher frequency of biliary pathology in said sex. It presents a high morbidity and mortality, mainly due to the difficulty and the diagnostic delay.

RESUMEN Introducción: Las fístulas aorto-entéricas son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Objetivo: Presentar el caso de una hemorragia digestiva por una fístula Aortoentérica diagnosticada y tratada. Presentación del caso: Se reporta el caso de un hombre de 72 años intervenido con el diagnóstico hemorragia digestiva masiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio, sin observar dilatación aneurismática, pero si una aorta ateromatosa y un proceso inflamatorio hacia la fístula. Se realizó reparación quirúrgica urgente con reparación cara anterior aorta infrarrenal cercana a la bifurcación y resección del íleo terminal con ileoascendentostomía termino-lateral. Discusión: Las fístulas aorto-entéricas es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación. Conclusiones: La fístula aorto-entérica primaria es una causa poco frecuente de hemorragia digestiva, que todo médico y cirujano debe tener en cuenta frente a un paciente con sangrado digestivo de causa no precisada(AU)

ABSTRACT Introduction: Aortoenteric fistulas are a rare cause of gastrointestinal bleeding. The generally ominous prognosis depends on high clinical suspicion and timely diagnosis. Objective: To present a case of gastrointestinal hemorrhage for aortoenteric fistula diagnosed and treated. Case presentation: The case is reported of a 72-year-old man who received surgery after the diagnosis of massive gastrointestinal bleeding during the preoperative period. However, the diagnosis of the fistula was made intraoperatively, without observing aneurysmal dilation, but an atheromatous aorta and an inflammatory process leading to the fistula instead. Urgent surgical repair was performed with repair of anterior infrarenal aorta near the bifurcation and resection of the terminal ileum with end-to-side ascending ileostomy. Discussion: Aortoenteric fistulas are a potentially fatal cause for gastrointestinal bleeding. Diagnosis continues to be a challenge due to its nonspecific presentation and should always be considered for any case of unexplained gastrointestinal bleeding. There are several options for surgical management that must be analyzed case by case, without delaying repair. Conclusions: Primary aortoenteric fistula is a rare cause for gastrointestinal bleeding, which every doctor and surgeon must take into account when dealing with a patient with digestive bleeding of an unspecified cause(AU)

Invaginación íleo-colónica en un paciente adolescente con fibrosis quística / Ileocolonic intussusception in an adolescent patient with cystic fibrosis

La invaginación intestinal ocurre cuando un segmento proximal de intestino se repliega dentro de la luz de un segmento distal adyacente y provoca obstrucción intestinal. Es una causa común de abdomen agudo en los dos primeros años de la vida, pero raro en niños mayores. Un varón de 16 años, con diagnóstico de fibrosis quística, se presentó con un cuadro compatible con síndrome de oclusión intestinal distal. Consultó a la clínica con dolor abdominal y una masa palpable en el hipocondrio derecho. Se realizó ecografía abdominal y tomografía de abdomen contrastada, que demostraron invaginación íleo-colónica con signos de isquemia intestinal, necrosis y neumatosis de la pared intestinal. Fue intervenido: se realizó resección del íleon terminal y hemicolon derecho, y se detectó una tumoración en ciego. La invaginación íleo-colónica es una causa rara de abdomen agudo en pacientes adolescentes con fibrosis quística y puede estar asociada a una causa orgánica subyacente.

Intestinal intussusception occurs when a proximal segment of the intestine telescopes into the lumen of an adjacent distal segment, causing intestinal obstruction. It is a common cause of acute abdomen in the first two years of life, but rare in older children. A 16-year-old male with a diagnosis of cystic fibrosis presented with symptoms compatible with distal intestinal occlusion syndrome. He came at the cystic fibrosis clinic with a 5-day evolution of abdominal pain and a palpable mass in the right hypochondrium. Abdominal ultrasound and abdominal contrasted tomography were performed demonstrating ileo-colonic invagination with signs of intestinal ischemia, necrosis and pneumatosis of the intestinal wall. He underwent surgery with resection of the terminal ileum and right hemicolon, ana tumor in the caecum was found. This is a rare cause of acute abdomen in young patients with cystic fibrosis and may be associated with an underlying organic cause.
