Diverticulitis aguda del intestino delgado como causa infrecuente de abdomen agudo en el adulto mayor: Reporte de caso / Acute diverticulitis of small bowel as rare cause of acute abdomen inthe elderly: Case report

Introducción. El dolor abdominal es uno de los principales motivos de admisión a urgencias y una de las causas más frecuentes es la enfermedad diverticular, que aumenta su prevalencia en el adulto mayor. Sin embargo, la diverticulitis del intestino delgado es una enfermedad infrecuente y en la mayoría de casos es asintomática. No obstante, la perforación de un divertículo intestinal es una complicación común de esta patología, por lo que debe ser considerado como un diagnóstico diferencial de abdomen agudo en este grupo poblacional. Caso clínico. Paciente masculino de 71 años, quien consultó por dolor abdominal de inicio súbito, con signos de irritación peritoneal al examen físico. Dado su deterioro hemodinámico fue llevado a cirugía y en la laparotomía exploratoria se halló una diverticulitis aguda perforada de yeyuno e íleon distal. Resultados. El paciente cursó con una adecuada evolución postoperatoria, sin reingresos. Conclusión. La diverticulitis aguda yeyuno-ileal es una causa importante, pero no frecuente de perforación intestinal. Hay muy pocos casos reportados en la literatura, lo que la convierte en un reto diagnóstico para el médico de urgencias y el cirujano general. No obstante, debe ser considerado como un diagnóstico diferencial en adultos mayores con abdomen agudo.

Introduction. Abdominal pain is one of the main reasons for admission to the emergency room and one of the most frequent causes is diverticular disease, which increases its prevalence in the elderly. However, diverticulitis of the small bowel is rare and in most cases asymptomatic. However, perforation of an intestinal diverticulum is a common complication of this pathology and should be considered as a differential diagnosis of acute abdomen in this population group. Clinical case. A71-year-old male patient presented with abdominal pain of sudden onset, with signs of peritoneal irritation. Given his hemodynamic deterioration, he was taken to surgery and in the exploratory laparotomy an acute perforated diverticulitis of the jejunum and distal ileum was found. Results. The patient had an adequate postoperative evolution, without readmissions. Conclusion. Acute jejuno-ileal diverticulitis is an important but uncommon cause of intestinal perforation. There are very few cases reported in the literature, which makes it a diagnostic challenge for the emergency physician and general surgeon. However, it should be considered as a differential diagnosis in older adults with acute abdomen.

Íleo biliar como causa de obstrucción intestinal en una paciente de 38 años con antecedentes de tres embarazos y cesárea: reporte de caso / Gallstone ileus-induced intestinal obstruction in a 38-year-old patient with a history of three pregnancies and cesarean section: a case report

RESUMEN La obstrucción intestinal inducida por íleo biliar es una condición rara pero significativa que se produce cuando una piedra en la vesícula se aloja en el tracto gastrointestinal. Entre los principales factores de riesgo para la obstrucción intestinal inducida por íleo biliar se encuentran la edad avanzada, el sexo femenino, la diabetes, los antecedentes de enfermedad biliar como cálculos biliares, así como procedimientos quirúrgicos previos relacionados con la vesícula biliar, como la colecistectomía. También el embarazo es un factor de riesgo conocido para la enfermedad de los cálculos biliares. En este artículo, se presenta el caso de una paciente de 38 años con antecedentes de tres cesáreas previas y sin comorbilidades aparentes. Antes de acudir al departamento de emergencias, la paciente experimentó dolor abdominal con cólico moderado en la parte inferior del abdomen durante dos días. El examen físico reveló sensibilidad abdominal difusa, predominantemente en la fosa ilíaca derecha, junto con signos de irritación peritoneal. Los análisis de laboratorio mostraron un recuento de leucocitos de 11 490 células/μl y una neutrofilia del 85,6 %. Después de una laparotomía exploratoria, se confirmó el diagnóstico sospechado de íleo biliar por cálculo. Se realizó una enterolitotomía y la paciente mostró un progreso posoperatorio favorable. En conclusión, es importante considerar la obstrucción intestinal inducida por íleo biliar en pacientes con síntomas relevantes y antecedentes médicos. Este reporte de caso subraya la importancia de considerar la obstrucción intestinal inducida por íleo biliar en pacientes con síntomas gastrointestinales y antecedentes de embarazo. El diagnóstico temprano y la intervención son cruciales para prevenir complicaciones graves.

ABSTRACT Gallstone ileus-induced intestinal obstruction is a rare but significant condition that occurs when a gallstone becomes lodged in the gastrointestinal tract. Major risk factors for gallstone ileus-induced intestinal obstruction include older age, female sex, diabetes, history of gallbladder disease such as gallstones, as well as previous gallbladder-related surgical procedures such as cholecystectomy. Pregnancy is also a known risk factor for gallstone disease. We present the case of a 38-year-old patient with a history of three cesarean sections and no apparent comorbidities. Prior to her visit to the emergency department, the patient experienced moderate colicky abdominal pain in the lower abdomen for two days. The physical examination revealed diffuse abdominal tenderness, predominantly in the right iliac fossa, along with signs of irritation of the peritoneum. Laboratory tests showed a leukocyte count of 11,490 cells/µl and neutrophilia of 85.6 %. Following an exploratory laparotomy, the suspected diagnosis of gallstone ileus was confirmed. An enterolithotomy was performed, and the patient experienced good post-surgical progress. In conclusion, it is important to consider gallstone ileus-induced intestinal obstruction among patients with relevant symptoms and medical history. This case report highlights the importance of considering gallstone ileus-induced intestinal obstruction among patients with gastrointestinal symptoms and a history of pregnancy. Early diagnosis and intervention are crucial to prevent serious complications.

Massive Gastrointestinal Bleeding Caused by Multiple Small Intestinal Diverticula: A Case Study

We report the case of a 71-year-old woman with multiple comorbidities who was admitted to the hospital due to hematochezia, without hemodynamic instability. Initial investigations, including colonoscopy and upper endoscopy, did not reveal the cause of bleeding. However, the patient experienced increased bleeding, anemia, and hemodynamic instability during her hospital stay. Subsequent selective angiography did not show any signs of active bleeding. In light of the persistent shock, surgical intervention was performed, which revealed blood originating from multiple diverticula in the jejunum.

Se presenta el caso de una mujer de 71 años con múltiples comorbilidades que ingresó por hematoquecia sin inestabilidad hemodinámica. Se inició el estudio con una colonoscopia sin evidenciar la causa; durante la estancia hospitalaria presentó un aumento del sangrado, anemización e inestabilidad hemodinámica, por lo que se realizó una endoscopia digestiva alta sin hallazgos; posteriormente, se realizó una angiografía selectiva sin evidencia de sangrado activo. Ante el choque persistente se llevó a cirugía en la que se evidenció sangre proveniente del intestino delgado secundaria a la presencia de divertículos múltiples en el yeyuno.

Structural and functional changes in the ileum of Parkinsonian cynomolgus monkeys / 中华老年心脑血管病杂志

Objective To study the changes in intestinal structure and function of Parkinson's dis-ease(PD)model in cynomolgus monkeys so as to provide scientific basis for exploring the mecha-nism and intervention of constipation and other intestinal symptoms in PD patients.Methods Six male cynomolgus monkeys were subjected,and three of them received intracarotid injection of MPTP for manifestations of typical PD motor symptoms.The monkeys with the Kurlan score reached 10 and persisting for over 3 months without abrogation were identified as PD model(PD group).The other three monkeys served as control group.The brain and ileum tissue samples were collected from the two groups of monkeys.Immunohistochemical staining with tyrosine hydroxy-lase(TH)was used to determine the number of dopaminergic neurons in the substantia nigra of the brain and the changes in peripheral TH of the intestine.HE staining was employed to observe the structure of the intestine.Intestinal permeability was evaluated by atresia occlusive zone pro-tein 1(ZO-1),and intestinal peristalsis function was assessed with intestinal pacemaker cell bio-markers oncogene c-kit and protein gene product 9.5(PGP9.5).Results When compared with the control group,the PD group had significantly less number of nigrostriatal dopaminergic neurons in the left and right sides(133.13±108.63 vs 957.21±225.56,t=5.705,P=0.005;155.74±62.48 vs 917.52±161.14,t=7.611,P=0.002),lower expression of TH in the ileal intermuscular plexus(0.79±0.01 vs 0.73±0.01,t=5.149,P=0.007),reduced villus density with irregular arrange-ment,scattered structure,and detachment of goblet cells,and increased expression of ZO-1(0.28± 0.01 vs 0.22±0.02,P=0.006)and c-kit(0.21±0.01 vs 0.18±0.01,P=0.007)in the ileum muco-sa,but there was no such difference in the expression of PGP9.5 between the two groups(0.31± 0.08 vs 0.38±0.06,P=0.322).Conclusion Intestinal barrier integrity is damaged in PD mon-keys,with damaged villi,increased intestinal permeability and decreased peristalsis,and peristaltic function related intermuscular neurons are not involved.

Analysis on Ileum and Colon Microflora of SPF Male SD Rats based on High-throughput Sequencing / 实验动物与比较医学

Objective To analyze the microflora structure and abundance of ileum and colon of SPF male SD rats by high-throughput sequencing technique. MethodsThe ileal and colonic lumen contents of 30 SPF male SD rats were collected, the total bacterial DNA in the contents was extracted and amplified by PCR. The V3-V4 region of bacterial 16S rRNA in the samples was sequenced using Illumina NovaSeq sequencing platform. Then the species structure and abundance of the intestinal flora were analyzed at the phylum and genus level based on validated data. The diversity and differences between ileal and colonic flora were analyzed using the QIIME software (amplicon) analysis tool. The Tax4Fun program was applied to predict the dominant gene enrichment pathways of ileal and colonic flora. ResultsAt the phylum level, the dominant microflora in the ileum of male SD rats were Firmicutes and Actinobacteria, accounting for more than 98%. The dominant colonic microbial community were mainly Firmicutes and Bacteroidetes, accounting for more than 95%. At the genus level, Lactobacillus and Alistipes were the predominant bacteria in the ileum. The colon was dominated by Lactobacillus and Romboutsia. In terms of flora diversity, the alpha diversity of colonic flora including richness index (Chao1 index) and diversity index (Shannon index) were significantly higher than those of ileum (P < 0.01), and the structural variability of the composition of its flora species was smaller than that of ileum; the ileal flora with significant structural variability were mainly of the phylum Firmicutes, Romboutsia, Peptostreptococcaceae, while the colonic flora had significant structural differences in Bacteroidales. In terms of flora function, the ileal flora dominant genes were significantly enriched in lipid-like metabolism, polyketide metabolism, membrane transport, biodegradation and other pathways, while the colonic flora dominant genes were significantly enriched in glycan biosynthesis metabolism, energy metabolism, biosynthesis of cofactor and vitamins and other products, and other pathways. ConclusionThere are significant differences in structure and abundance between the ileal and colonic flora of SPF male SD rats, and the abundance and diversity of colonic flora are higher than those of ileal flora.

Effects of Weichang'an Pill on contraction of isolated ileum smooth muscles in rats / 中国药理学通报

Aim To investigate the impact and mechanism of Weichang'an Pill(WCA),its ethanol extract(EE),water extract(WE),and active ingredients on the contraction of isolated rat ileum smooth muscles induced by acetylcholine(ACh). Methods In vitro tissue bath experiment,WCA,EE,WE,or their active ingredients were added under the action of ACh,and then the contraction tension of isolated ileum smooth muscle from rats was recorded. The binding affinity ofthe active ingredients to the muscarinic acetylcholine M3 receptor was explored by molecular docking. Results WCA,EE,and WE were able to considerably inhibit the excitatory contraction of the ileal smooth muscles induced by ACh. Costunolide,dehydrocostus lactone,santalol,muscone,emodin,chrysophanol,physcion,crotonoside,magnolol,and honokiol were also significantly effective against ACh-induced ileal smooth muscle contraction. Conclusions WCA,EE,WE,and their active ingredients may help to promote intestinal smooth muscle relaxation by blocking the binding of the M3 receptor on the membrane of ileal smooth muscle with ACh.

Isolated intestinal neuronal dysplasia- type B of ileum: A rare occurrence

Intestinal neuronal dysplasia type B in the gastrointestinal tract is a rare occurrence and may occur alone or in combination with Hirschsprung disease. Distal colon seems to be a frequent site for isolated IND-B cases; however, small bowel involvement is scarcely reported. We report a case of 9 years old boy presenting with features of intestinal pseudo-obstruction for 5 years. Exploratory laparotomy revealed narrowed distal ileum with huge proximal dilatation. Histopathology of the resected terminal ileum revealed giant submucosal ganglion, hyperplastic submucosal nerves, and ectopic ganglion cells in the lamina propria suggestive of IND-B. Although IND-B involving ileum in isolation is a rare occurrence, suspicion should be kept in cases of intestinal obstruction with minimal response to conventional treatment.

Ileal fecaloma in a 2-month healthy boy

A fecaloma is a fecal matter that builds up to form a hard mass of feces that is extremely rigid than a mass connected with fecal impaction. Fecalomas are commonly in the rectosigmoid region. Our report aimed to give a brief review of this case and discuss the treatment options for it. A 2-month-old male presented with bowel obstruction and a palpable mass on the right side of the abdomen. A simple abdominal radiograph and contrasted abdominal computed tomography scan were performed immediately, resulting in small intestine mechanical obstruction. A 4.6 � 6.6 � 4 cm fecaloma was found in the distal ileum. We consequently diagnosed a case of ileal fecaloma producing small bowel obstruction. The patient was surgically managed after conservative treatment failed.

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.

Obstrucción intestinal por íleo biliar: reporte de un caso

El íleo biliar (IB) se define como la obstrucción intestinal mecánica intraluminal por uno o más cálculos biliares que han emigrado a través de una fístula biliodigestiva, establecida como complicación de una colelitiasis. Presentamos el caso de una mujer de 59 años con antecedente de hipertensión arterial, con diagnóstico tomográfico preoperatorio de obstrucción intestinal por íleo biliar (triada de Rigler), por lo que es intervenida quirúrgicamente de emergencia, decidiéndose realizar una enterolitotomía y programar su segunda intervención en dos meses. El IB es una causa infrecuente de obstrucción intestinal en pacientes de edad avanzada, con una elevada morbi-mortalidad. Requiere un alto índice de sospecha ante un cuadro de oclusión intestinal intermitente y antecedente de cólicos biliares. La triada de Rigler solo está presente en un tercio de los pacientes, para lo cual la tomografía es el estudio de elección. El tratamiento es controversial, pero el más empleado es la enterolitotomía.

Gallstone ileus (BI) is defined as intraluminal mechanical intestinal obstruction by one or more gallstones; who have emigrated through a biliodigestive fistula, established as a complication of cholelithiasis. We present the case of a 59-year-old woman with a history of arterial hypertension, with a preoperative tomographic diagnosis of intestinal obstruction due to biliary ileus (Rigler's triad), for which she underwent emergency surgery, deciding to perform an enterolithotomy and schedule her second intervention in two months. BI is an uncommon cause of intestinal obstruction in elderly patients, with high morbidity and mortality. It requires a high index of suspicion in the presence of intermittent intestinal obstruction and a history of biliary colic. Rigler's triad is only present in a third of patients, for which tomography is the study of choice. Treatment is controversial, but the most widely used is enterolithotomy.

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)

Comparative study of single and double ileal Yang-Monti duct controllable outflow tract in patients with urethral damage / 中华泌尿外科杂志

Objective:To evaluate the efficacy and safety of Yang-Monti tube in the operation of bladder controllable outflow tract, and to compare the efficacy of single and double segments Yang-Monti tube in patients with urethral damage.Methods:The clinical data of 27 patients who underwent Yang-Monti tube surgery in West China Hospital of Sichuan University from January 2009 to February 2018 were retrospectively analyzed, including 14 cases of single segment ileum (single segment group) and 13 cases of double segment ileum (double segment group). The age of single-segment group and double-segment group was (56.5±4.3) years and (50.2±6.8) years, respectively ( P=0.220). There were 2/12 and 3/10 males and females, respectively ( P=0.564). The body mass index (BMI) was (19.6±1.3) kg/m2 and (24.2±2.1) kg/m2, respectively ( P<0.001). The disease duration was 6 (3-24) months and 8 (3-48) months, respectively ( P=0.650). The preoperative quality of life (QOL) score was (46.7±1.7) and (45.5±1.7), respectively ( P=0.061). The number of patients with urinary tract infection before operation was 11 and 13, respectively ( P=0.480). In the single-segment group, a 2 cm ileum with mesangial vessels was cut at a distance of about 15 cm from the ileocecal part, and the intestine was cut longitudinally along the direction of the intestinal canal at the opposite mesangial margin. The intestinal piece was wrapped horizontally around the F12 urinary tube and wound into a Yang-Monti tube by intermittent suture with a 3-0 single thread. The bladder wall was cut anterolateral to the top wall of the bladder, about 1 cm in length, and the Yang-Monti tube was anastomosed end-to-end with the mucosal muscularis of the bladder wall. A circular incision with a diameter of about 1 cm was made at the level of the anterior superior iliac spine at the rectus abdominis muscle, and a tunnel was formed by puncture into the abdomen with curved forceps. The Yang-Monti tube was led out of the abdominal wall along the tunnel, and the tube opening was fixed with subcutaneous suture. At the same time, the tube wall was fixed in the peritoneum with 4-0 silk thread. In the double-segment group, two segments of 2 cm ileum were cut, and the intestinal tube was cut longitudes along the direction of the opposite mesangial margin. The intestinal piece was first sutured end to end, and then the tube was coiled and reconstructed to form a Yang-Monti tube with a diameter of 0.6-0.8 cm and a length of about 12 cm. The proximal end of the Yang-Monti tube was directly anastomosed with the mucosal muscle layer of the bladder. The operation time, intraoperative blood loss, postoperative catheterization interval, postoperative single catheterization volume, postoperative complications (bleeding, intestinal obstruction, anastomotic leakage, anastomotic stenosis, stoma infection, urinary tract infection, urinary tract infection) and QOL score were compared between the two groups. Results:The operation was successfully completed in both groups. The operation time of single-segment group and double-segment group were (165.8±17.8) min and (157.54±12.25) min, respectively ( P=0.302), and the intraoperative blood loss was (60.0±20.0) ml and (50.00±25.00) ml, respectively ( P=0.650). The postoperative recovery time was 3 (2-4) d and 3 (2-9) d, respectively ( P=0.790), and the postoperative hospital stay was 12 (9-40) d and 12 (10-32) d, respectively (P=0.259). The postoperative single catheterization volume was (240.4±42.7) ml and (261.5±36.3) ml ( P=0.186), and the postoperative QOL was (22.4±2.7) and (21.5±2.6), respectively ( P=0.325), and there was no significant difference. There were 2 cases of urinary tract infection in the single-segment group, and 1 case of urinary tract infection, postoperative bleeding, and intestinal obstruction in the double-segment group. There was no significant difference between the two groups ( P=0.222). The time interval of catheterization in single-segment group and double-segment group was (2.5±1.0) h and (3.5±1.3) h, respectively, and the difference was statistically significant ( P=0.029). The quality of life score after operation was statistically significant compared with that before operation ( P<0.001), and the incidence of urinary tract infection after operation was also statistically significant compared with that before operation ( P=0.011). Conclusions:Both single segment and double segment ileum Yang-Monti tube surgery are feasible surgical methods for patients with urethral damage. There was no difference in the effects of the two types of surgery, and both may improve the quality of life of patients.The postoperative QOL score could be greatly improved and the incidence of complications was low.

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.

Íleo biliar: una causa infrecuente de oclusión intestinal. Presentación de un caso clínico

RESUMEN El íleo biliar es una causa poco frecuente de obstrucción intestinal mecánica. Generalmente se ve en pacientes adultos mayores del sexo femenino con antecedentes de ser portadores de litiasis vesicular, representando solamente del 1 al 6% de las obstrucciones intestinales diagnosticadas. Se presenta el caso de una paciente femenina de 66 años de edad con antecedentes de presentar cólicos a repetición por litiasis vesicular, la cual acude al cuerpo de guardia de nuestro centro por dolor abdominal vómitos y distención abdominal. Se comprobó en el acto quirúrgico la presencia de un íleo biliar. Se concluye que entre las causas infrecuentes de oclusión intestinal mecánica podemos citar el íleo biliar, lo cual lo corrobora el hecho de que en el servicio de cirugía de nuestro centro solo tenemos dos casos anteriores reportados.

ABSTRACT Gallstone ileus is a rare cause of mechanical bowel obstruction. It is generally seen in older female patients with a history of being carriers of gallstones, representing only 1 to 6% of diagnosed intestinal obstructions. A case of a 66-years-old female patient with a history of recurrent colic due to gallstones, who came to the guardhouse of the hospital for abdominal pain, vomiting and abdominal distention, it is presented. The presence of a gallstone ileus was verified in the surgical act. It is concluded that among the infrequent causes of mechanical intestinal occlusion can be mentioned gallstone ileus, which is corroborated by the fact that in the surgery service of the hospital only have two previous reported cases.

Se realizaron procedimientos endoscópicos como: biopsias, tatuajes, resección y dilatación en 40 (88,9%), 39 (86,7%), 4 (8,9%) y 1(2,2%) paciente respectivamente. La localización más frecuente fue yeyuno en 39 (86%). Se confirmó GIST en 18 (40%), seguido de linfoma en 16 (35,6%) y adenocarcinoma en 5 (11%) casos. Todos los tumores GIST, adenocarcinoma y neuroendocrinos se sometieron a tratamiento quirúrgico y quimioterapia; el tratamiento de los linfomas consistió en tratamiento combinado principalmente; tres harmartomas y un fibroangiolipoma fueron resecados endoscópicamente. Conclusiones : Los tumores de intestino delgado yeyuno-ileal más frecuentes fueron los GIST, seguidos de linfomas y adenocarcinomas. La enteroscopia de doble balón fue la principal herramienta diagnóstica y terapéutica.

ABSTRACT Introduction : Primary tumors of the small intestine (PTID) represent approximately 5% of all primary gastrointestinal neoplasms; the latter include benign and malignant lesions, with different histological subtypes. Objective : To describe the clinical-pathological characteristics and the management of tumors located in the jejunum-ileum. Materials and methods : A descriptive, retrospective study was carried out in a single center. Results : 45 patients were included, the average age at diagnosis was 54.2 ± 8.2 years. 27 were male (60%). In the diagnostic algorithm, computed tomography was used in all patients, double-balloon enteroscopy in 41 (91.1%) and video capsule endoscopy in 32 (71.1%). Endoscopic procedures such as: biopsies, tattoos, resection and dilation were performed in 40 (88.9%), 39 (86.7%), 4 (8.9%) and 1 (2.2%) patients, respectively. The most frequent location was the jejunum in 39 (86%). GIST was confirmed in 18 (40%), followed by lymphoma in 16 (35.6%) and adenocarcinoma in 5 (11%) cases. All GIST, adenocarcinoma, and neuroendocrine tumors underwent surgical treatment and chemotherapy; treatment of lymphomas consisted mainly of combined treatment; three harmartomas and one fibroangiolipoma were resected endoscopically. Conclusions : The most frequent jejunoileal small intestine tumors were GISTs, followed by lymphomas and adenocarcinomas. Double-balloon enteroscopy was the main diagnostic and therapeutic tool.

Clinical Application of Transparent Cap in Retrograde Single-balloon Enteroscopy / 胃肠病学

Background: Enteroscopy-based biopsy pathology has high diagnostic value for suspected small bowel diseases. Retrograde single-balloon enteroscopy (SBE) is difficult to operate due to the influence of colonic segment. Transparent cap has been widely used in the diagnostic and therapeutic endoscopic procedure, which is conducive for inserting the enteroscope and stabilizing the intestinal cavity. Aims: To explore the role of transparent cap in retrograde SBE. Methods: A total of 64 cases of patients who were hospitalized for retrograde SBE in Suzhou Wuzhong People's Hospital were recruited and allocated into 2 groups according to the random number table method, with 32 cases in each group. Patients in experimental group received cap-assisted SBE and those in control group received routine SBE. All procedures were performed by an experienced senior endoscopist. Outcomes measured included time to reach the ileocecus, terminal ileum intubation rate, depth of insertion, diagnostic yield, and the related complications. Results: The mean time to reach the ileocecus was shorter in experimental group than in control group [(11.8±2.0) min vs. (13.6±2.8) min, P0.05). No severe complications were observed in all the cases. Conclusions: Cap-assisted retrograde SBE is an efficient method for optimizing the intubation rate, insertion depth and procedure time, and is suitable for promotion in clinical practice.

Association of colonoscopy and histopathological findings of the canine large intestine and ileum abnormalities: 54 cases series / Associação de achados de colonoscopia e histopatologia do intestino grosso e íleo de cães: série de 54 casos

Colonoscopy is a minimally invasive technique used to assess the large intestine through direct inspection of the intestinal mucosa. When associated with histopathological examination of fragments collected from the intestine, the definitive diagnosis can be obtained. This retrospective study evaluated colonoscopy and histopathological exams of the large intestine and ileum of dogs with gastrointestinal disorders admitted at the Veterinary Hospital of the Federal University of Minas Gerais (UFMG) and the Veterinary Hospital São Francisco de Assis to determine the frequency of injuries, their distribution in the intestinal segments, and the relationship of the findings observed in these two analyzes. The colonoscopy and histopathological findings of the case series were described using absolute and relative frequencies, as well as nature and intensity classification of the findings. Cohen's Kappa coefficient was obtained to assess the concordance of nature and intensity classifications between colonoscopy and histopathology, and its 95% confidence interval constructed. The analyses were performed using the Software SAS University Edition. It was observed a moderate agreement between the classification of the nature of the findings by endoscopy and histopathology (Kappa coefficient = 0.39, CI = 0.20-0.59). This can also be observed when assessing the frequency of similar diagnoses between the methods, since only 39 (72.22%) were consistent, i.e., 15 (22.78%) diagnoses differed depending on the nature of the finding, which could have a great influence on the final diagnosis if histopathology was disregarded. For the intensity of the injuries, little agreement was observed between the methods (Kappa coefficient = 0.1243, C = -0.05-0.30). This was even more evident in the frequency of similar diagnoses in terms of intensity, of which 20 (37.04%) were similar and 34 (62.96%) were different. Inflammatory affections are the most frequently observed alterations in the large intestine and ileum of dogs. The most common finding that reveals inflammatory changes is the lymphoplasmacytic infiltrate. As for the proliferative and neoplastic lesions, adenomatous polyps and lymphoma were common. The most affected sites of the large intestine were the descending colon and the rectum. Findings such as edema and reddening of the mucosa were frequent by macroscopy. Although the changes observed by colonoscopy and histopathology may not be similar, these techniques are complementary, which makes biopsies mandatory for a diagnostic conclusion.(AU)

A colonoscopia é uma técnica pouco invasiva utilizada para avaliação do intestino grosso por meio de inspeção direta da mucosa intestinal. Quando associada ao exame histopatológico, com a coleta de fragmentos do intestino, o diagnóstico definitivo pode ser obtido. O objetivo desse estudo retrospectivo foi associar os achados de exames de colonoscopia e histopatologia do intestino grosso e íleo em 54 cães com distúrbios gastrointestinais dos Hospitais Veterinários da Universidade Federal de Minas Gerais (UFMG) e São Francisco de Assis. Na colonoscopia, as alterações mais frequentemente observadas foram edema, friabilidade e avermelhamento de mucosa. Quanto à distribuição de lesões por segmento intestinal, houve maior incidência de alterações inflamatórias, das quais foram as mais frequentes, com o infiltrado linfoplasmocitário sendo o mais comum em todos segmentos analisados (i.e. reto, cólon, ceco e íleo). O cólon ascendente e o reto foram os locais de alterações mais frequentes na colonoscopia e na histopatologia. Os pólipos hiperplásicos e o linfoma foram as lesões proliferativas de ocorrência mais comum. Houve baixa concordância entre as classificações por natureza e intensidade dos achados na colonoscopia e histopatologia. Assim, não foi possível associar alterações descritas nos exames histopatológicos quanto à natureza e intensidade das lesões utilizando a colonoscopia, o que leva à conclusão de que é essencial a realização de biópsias em todos os exames para conclusão diagnóstica.(AU)

Caso infrecuente de oclusión intestinal por vólvulo de íleon / Infrequent case of intestinal occlusion due to ileum volvulus

Introducción: La oclusión intestinal mecánica es una enfermedad frecuente en los servicios quirúrgicos, sin embargo el vólvulo de intestino delgado es una de sus causas poco frecuentes. Objetivos: Describir las características clínicas de un caso de oclusión intestinal por vólvulo de íleon. Caso clínico: Paciente masculino de 63 años, con antecedentes de etilismo y pancreatitis crónica, para lo cual no llevaba tratamiento regular. Acudió al cuerpo de guardia por dolor abdominal de aproximadamente 24 horas de evolución. Presentó dos vómitos con restos alimentarios, sin fiebre u otros síntomas de interés. Semiotécnicamente el dolor era mantenido, difuso en todo el abdomen, intenso, punzante, no se aliviaba con analgésicos, sin otros síntomas acompañantes. Se realizaron estudios de laboratorio e imagenológicos, los resultados fueron sugerentes de un síndrome oclusivo y/o perforativo. Se decidió tratamiento quirúrgico, se diagnosticó una oclusión intestinal por vólvulo de íleon. Conclusiones: El diagnóstico del vólvulo de intestino delgado, requiere un alto índice de sospecha, debido a lo infrecuente en el adulto. Los hallazgos de imagen son de utilidad en el diagnóstico temprano. El tratamiento es eminentemente quirúrgico; se impone la resección intestinal del segmento afectado siempre que el tejido intestinal no sea viable(AU)

Introduction: Mechanical intestinal occlusion is a common disease in surgical services, however small bowel volvulus is one of its rare causes. Objectives: To describe the clinical characteristics of a case of intestinal occlusion due to ileum volvulus. Clinical case: A 63-year-old male patient, with a history of ethylism and chronic pancreatitis, for which he did not have regular treatment. He went to emergency due to abdominal pain of approximately 24 hours of evolution. He presented two vomits with food debris, without fever or other symptoms of interest. Semiotechnically the pain was maintained, diffuse throughout the abdomen, intense, stabbing, it was not relieved with analgesics. No other accompanying symptoms. Laboratory and imaging studies were performed, the results were suggestive of an occlusive and/or perforative syndrome. Surgical treatment was decided, an intestinal occlusion was diagnosed by ileum volvulus. Conclusions: The diagnosis of the small intestine volvulus requires a high index of suspicion, due to the infrequent occurrence in the adult. Image findings are useful in early diagnosis. The treatment is eminently surgical; Intestinal resection of the affected segment is imposed as long as the intestinal tissue is not viable(AU)
