The value of ultrasound in diagnosis of neonatal upper and lower gastrointestinal perforation / 中国小儿急救医学

Objective To explore the value of ultrasound in the differential diagnosis of neonatal upper and lower gastrointestinal tract ( GIT) perforation. Methods We retrospectively reviewed the ultra-sound findings of 42 neonates of surgery-confirmed neonatal GIT perforation in our hospital from January 1, 2015 to December 31,2018. The accuracy of ultrasound for detecting GIT perforation and the ultrasound fea-tures of upper and lower GIT perforation were evaluated. Results (1)Of the 42 neonates with GIT perfora-tion,1 case didn′t undergo ultrasound,2 cases were missed,and 1 case was misdiagnosed. Thirty-eight neo-nates were diagnosed of GIT perforation by ultrasound preoperatively,with a detection rate of 92. 7%(38/41). The locations of GIT perforation were identified by ultrasound in 30 cases(78. 9%,30/38),including 11 cases of upper GIT perforation and 19 cases of lower GIT perforation. (2)A common sonographic finding of GIT perforation in 38 cases was pneumoperitoneum,which appeared as an echogenic line with posterior rever-beration artifact under diaphragm or anterior to hepatic/splenic surface and a "stratosphere" sign in M-mode sonography. Free gas changed position when the patient′s position was changed,and didn′t change due to re-spiratory change. Besides,free gas dispersed with compression on abdomen,and gathered without compres-sion. (3)Upper GIT perforation was showed that poor filling of the stomach cavity,and the abdominal free gas sharply increased. Lower GIT perforation was characterized by collapsed bowel,blurred and interrupted intestinal wall structure, and more accompanied with intestinal obstruction. ( 4 ) There was no significant difference of detection rate between ultrasound and X-ray in diagnosing GIT perforation [92. 7%(38/41) vs. 83. 3%(35/42)]( P>0. 05),whereas ultrasound more sensitive for a very small amount of free gas in the early stage of perforation. (5) Helicobacter pylori infection was found in two cases of GIT perforation. Conclusion Ultrasound can be used for differential diagnosis of upper and lower GIT perforation,and could be recommended as the first choice for detecting GIT perforation in neonatal patients.

Factores asociados a mal pronóstico en pacientes con sangrado digestivo bajo en un hospital público / Poor outcome factors associated to patients with lower digestive bleeding in a public hospital

Introducción: El sangrado digestivo bajo (SDB) es una entidad cuyas tasas de complicaciones y mortalidad se han incrementado en las últimas décadas. Si bien se han identificado algunos factores relacionados a mal pronóstico, aún quedan variables por evaluar. Objetivo: Identificar factores de mal pronóstico en pacientes que presentaron SDB en el Hospital Nacional Edgardo Rebagliati Martins de Lima, Perú. Materiales y métodos: Se realizó un estudio observacional analítico de tipo cohorte retrospectivo. Se realizó un censo de todos los pacientes que presentaron SDB agudo entre enero 2010 y diciembre 2013. Las variables principales a evaluar fueron frecuencia cardiaca ≥100/min, presión arterial sistólica <100 mmHg y hematocrito bajo (≤35%) al ingreso. Se definió mal pronóstico como cualquiera de los siguientes criterios: muerte durante la hospitalización, sangrado que requiera transfusión de ≥4 unidades de sangre, reingreso dentro del primer mes, o necesidad de cirugía de hemostasia. Resultados: Se incluyó un total de 341 pacientes con SDB, de los cuales el 27% tuvo mal pronóstico y 2% fallecieron. Se encontró como variables asociadas a mal pronóstico: frecuencia cardiaca ≥100/min al ingreso (RR: 1,75, IC 95% 1,23-2,50), presión arterial sistólica <100 mmHg al ingreso (RR: 2,18, IC 95% 1,49-3,19), hematocrito ≤35% al ingreso (RR: 1,98, IC 95% 1,23-3,18) y sangrado de origen no determinado (RR: 2,74, IC 95% 1,73-4,36). Conclusiones: Frecuencia cardiaca elevada al ingreso, hipotensión sistólica al ingreso, hematocrito bajo al ingreso y presentar un sangrado en el cual no se encuentra el punto de origen son factores que incrementan el riesgo de presentar mal pronóstico, por lo que se recomienda un monitoreo más estricto en estos pacientes

Background: Lower gastrointestinal bleeding (LGIB) is an event that has shown an increase in complications and mortality rates in the last decades. Although some factors associated with poor outcome have been identified, there are several yet to be evaluated. Objective: To identify risk factors for poor outcome in patients with LGIB in the Hospital Edgardo Rebagliati Martins of Lima, Peru. Material and methods: A prospective analytic observational cohort study was made, and a census was conducted with all patients with acute LGIB between January 2010 and December 2013. The main variables were heart rate ≥100/min, systolic blood pressure <100 mmHg and low hematocrit (≤35%) at admission. Poor outcome was defined as any of the following: death during hospital stay, bleeding requiring transfusion of ≥4 blood packs, readmission within one month of hospital discharge, or the need for hemostatic surgery. Results: A total of 341 patients with LGIB were included, of which 27% developed poor outcome and 2% died. Variables found to be statistically related to poor outcome were: heart rate ≥ 100/min at admission (RR: 1.75, IC 95% 1.23-2.50), systolic blood pressure <100 mmHg at admission (RR: 2.18, IC 95% 1.49-3.19), hematocrit ≤35% at admission (RR: 1.98, IC 95% 1.23-3.18) and LGIB of unknown origin (RR: 2.74, IC 95% 1.73-4.36). Conclusions: Elevated heart rate at admission, systolic hypotension at admission, low hematocrit at admission and having a LGIB of unknown origin are factors that increase the risk of developing poor outcome, and these patients should be monitored closely due to their higher risk of complications

Hematochezia due to Angiodysplasia of the Appendix

Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleeding from the orifice of the appendix. We performed a laparoscopic appendectomy. Microscopically, dilated veins were found at the submucosal layer of the appendix. The patient was discharged uneventfully. Although lower gastrointestinal bleeding of appendiceal origin is very rare, clinicians should consider it during differential diagnosis.

Non-Steroidal Anti-Inflammatory Drug-Induced Enteropathy

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed drugs in the world. NSAID-induced lower gastrointestinal (GI) complications are increasing while upper GI complications are decreasing. Lower GI events accounted for 40% of all serious GI events in patients on NSAIDs. Capsule endoscopy and device assisted enteroscopy are available for detection of small intestinal lesions. Capsule endoscopy studies have demonstrated that NSAIDs use in healthy volunteers raised the incidence (55% to 75%) of intestinal damage. It appears that selective cyclooxygenase-2 inhibitors (coxibs) improved upper and lower GI safety based on results of clinical trials. Selective coxibs are still capable of triggering GI adverse events and cardiovascular toxicity issues were the main focus of concerns. Unfortunately, definite strategies are not available to prevent or heal NSAID-induced intestinal injuries. Thus, there is still a strong clinical need for effective drugs with improved safety profiles than the existing NSAIDs.

International Digestive Endoscopy Network to Strengthen Network for Lower Gastrointestinal Diseases Including Inflammatory Bowel Disease and Colorectal Cancer

The International Digestive Endoscopy Network 2012 organized by Korean Society of Gastrointestinal Endoscopy was held at Seoul, Korea on June 9 to 10, 2012, during which invited lectures of world renowned experts on the lower gastrointestinal (GI) tract were given with a wide range of the latest knowledge and novel imaging of inflammatory bowel disease (IBD) and colorectal endoscopic submucosal dissection (ESD). There were very informative five sessions in the lower GI part consisting of: Colonoscopy in IBD; what can we do in 2012?; A look into the bowel beyond colon in IBD; How to estimate the invasion depth of early GI cancer?; No more no man's land: small bowel exploration; and colorectal ESD: can it be a popular procedure?

Clinical Observation after Resection of Lower Gastrointestinal Carcinoid Tumor

BACKGROUND/AIMS: The increase of colonoscopy procedures has led to an increase in the diagnosis of carcinoid tumors in the lower gastrointestinal tract. The purpose of this study was to identify the clinical and pathological characteristics that affect the treatment and recurrence of carcinoid tumors of the lower gastrointestinal tract. METHODS: A 10-year (1999-2009) retrospective analysis of 41 patients with carcinoid tumors of the lower gastrointestinal tract at the Chungbuk National University Hospital was conducted. Patient and tumor characteristics, treatment and recurrence were analyzed. RESULTS: The mean age was 47.4+/-12.4 (range, 22-79 years) and the male to female ratio was 1:0.64. The mean tumor size was 9.4+/-4.8 (3-20) mm. In the lower gastrointestinal tract, the rectum was the most frequent location of the lower gastrointestinal carcinoid tumors (92.7%). Twenty-nine out of 41 patients were treated by endoscopy (mean size of tumor: 8.0+/-3.4 mm) and 12 were treated by surgery (mean size of tumor: 13.8+/-5.8 mm)(P=0.011). Among the patients treated by endoscopy, only one patient had a complete resection. However, the histology showed that 10 patients treated by endoscopy had positive resection margins; all 10 cases (35.7%) had a polypectomy (P=0.013). The mean follow-up duration was 19.2+/-14.5 months, and there were two recurrences of rectal carcinoid tumors. CONCLUSIONS: Both endoscopic and surgical resections were effective methods for the treatment of lower gastrointestinal carcinoid tumors. However, endoscopic polypectomy should be carefully considered because of the possibility of more frequent incomplete histological resections. Moreover, even for small rectal carcinoid tumors, follow-up examination should be performed to evaluate for tumor recurrence.

Colitis ulcerosa inespecífica como causa de hemorragia digestiva baja: caso pediátrico a propósito de diagnóstico diferencial y manejo / Nonspecific ulcerative colitis as a cause of lower gastrointestinal bleeding: a pediatric case purpose differential diagnosis and management

Se describe el caso clínico de una niña, de dos años y cuatro meses de edad, que consulta por rectorragia severa, luego de una disentería. La colonoscopía realizada a las tres horas del sangrado, reveló úlceras en todo el colon y el estudio histopatológico describe una colitis ulcerativa crónica en fase activa; es manejada solo condieta, probióticos y ceftriaxona, con mejoría del cuadro clínico. Dos colonoscopías de control muestran rectosigmoiditis inespecifica, con franca remisión de las úlceras. La estadística de colitis ulcerosa(CU) registrada en el Instituto Gastroenterológico Boliviano Japonés de La Paz, donde también se realizan todos los estudios endoscópicos del Hospital del Niño, muestra que el caso expuesto corresponde a la niña de menor edad reportada en nuestro medio hasta la fecha de la presente divulgación, aun que está descrita en laliteratura internacional la CU en lactantes de meses de edad (2). Esta circunstancia, junto a la remisión sin el uso de drogas específicas para la CU de la enfermedad inflamatoria intestinal (EII), obligan aplantear el diagnóstico diferencial con otras entidades que originan hemorragia digestiva baja con úlceras colónicas. Lo anterior, junto a los hallazgos endoscópico e histopatológico que inicialmente sugerían una CU como parte de la EII, la remisión progresiva consolo medidas dietéticas a perfilado el diagnóstico fi nal de una colitis ulcerosa inespecífica que amerita diagnósticos diferenciales por su evolución y por la rectorragia importante que ocasionó, por lo que el autor considera la justificación de esta publicación.

We describe the case of a 2 years and 4 months old girl who was admitted to the hospital for severe bleeding from the rectum after dysentery. Colonoscopy made three hours after the bleeding showed ulcers throughout the colon and the histopathologic exam described an active phase of chronic ulcerative colitis. The treatment is only diet, probiotics and ceftriaxone and the child’s state improves. Two control colonoscopies show an unspecific rectosigmoiditis with a clear remission of the ulcers. Statistics of ulcerative colitis (CU)recorded in the Instituto Gastroenterológico Boliviano Japonés of La Paz, where all the endoscopic studies of the Children’s Hospital are carried out, shows that the present case corresponds to the youngest girl ever reported until now, even though in the international literature, CU is described in babies of only months of age (2). This fact together with the remission of the infl ammatory intestinal disease (EII) without use of CU specifi c drugs, make it necessary to think of differential diagnoses with other diseases with colon ulcers that cause bleedings of the lower gastrointestinal tract. The above together with the endoscopic and histopathologic fi ndings that initially suggested a CU as part of the EII, the progressive remission with only dietetic measures, has drawn the fi nal diagnose of an unspecifi c ulcerative colitis that needs differential diagnosis due to its evolution and the important bleeding that it caused. For these reasons, the author considers this publication justifi ed.

Relation between Location of Pelvic bone Fractures and the Injury to the Urinary bladder, Urethra or Lower gastrointestinal tract

PURPOSE: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. METHODS: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher's-exact test and multiple logistic regression. RESULTS: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). CONCLUSION: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

A Case of Acute Lower Gastrointestinal Bleeding from Appendiceal Ulcer / 대한소화기내시경학회지

The common causes of acute lower gastrointestinal bleeding include diverticulosis, colonic vascular ectasia, neoplasm and colitis. Acute lower gastrointestinal bleeding from the appendix is a very rare malady and the causes are reported as angiodysplasia, diverticulum, appendicitis and endometriosis. We report here on the case of a 47-year-old man, who was taking enteric coated aspirin, with severe lower gastrointestinal bleeding that was due to appendiceal ulcer. An active bleeding was identified as coming from the appendiceal orifice during colonoscopy. He was treated by simple appendectomy. Histologic evaluation showed ulceration with both acute and chronic inflammation, along with thickened vessel walls in the submucosa of the appendix.

Benign Solitary Cecal Ulcer Accompanied by Massive Lower Gastrointestinal Tract Hemorrhage

A benign cecal ulcer is an uncommon lesion. The etiology remains unknown, and there are no pathognomonic lesions or symptoms. Lower gastrointestinal tract hemorrhage secondary to benign cecal ulcer is the most common complication. Herein, the case of a 24-year-old man with a benign cecal ulcer presenting with a massive lower gastrointestinal tract hemorrhage requiring transfusion until a exploratory laparotomy and right hemicolectomy, is reported with a review of the literature. Surgical intervention is warranted if malignancy is suspected or if the patient has signs of uncontrollable hemorrhage, perforation, or peritonitis.
