Acute prostatitis after prostate biopsy under ciprofloxacin prophylaxis with or without ornidazole and pre-biopsy enema: analysis of 3. 479 prostate biopsy cases

ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

Enemas with mesalazine increase the tissue contents of mucins in the colonic mucosa devoid of fecal stream

Abstract Purpose: To evaluate the inflammatory reaction and measure the content of mucins, in the colonic mucosa without fecal stream submit to intervention with mesalazine. Methods: Twenty-four rats were submitted to a left colostomy and a distal mucous fistula and divided into two groups according to euthanasia to be performed two or four weeks. Each group was divided into two subgroups according daily application of enemas containing saline or mesalazine at 1.0 g/kg/day. Colitis was diagnosed by histological analysis and the inflammatory reaction by validated score. Acidic mucins and neutral mucins were determined with the alcian-blue and periodic acid of Schiff techniques, respectively. Sulfomucin and sialomucin were identified by high iron diamine-alcian blue technique. The tissue contents of mucins were quantified by computer-assisted image analysis. Mann-Whitney test was used to analyze the results establishing the level of significance of 5%. Results: Enemas with mesalazine in colonic segments without fecal stream decreased the inflammation score and increased the tissue content of all subtypes of mucins. The increase of tissue content of neutral, acid and sulfomucin was related to the time of intervention. Conclusion: Mesalazine enemas reduce the inflammatory process and preserve the content of mucins in colonic mucosa devoid of fecal stream.

Adequate rectal preparation reduces hospital admission for urosepsis after transrectal ultrasound - guided prostate biopsy

ABSTRACT Objectives: Previous studies have compared infectious outcomes on the basis of whether rectal preparation was performed; however, they failed to evaluate the quality of each rectal preparation, which may have led to confounding results. This study aimed to compare hospitalizations for urosepsis within 1 month after transrectal ultrasound-guided prostate biopsy between patients with adequate and traditional rectal preparations. Materials and Methods: Between January 2011 and December 2016, a total of 510 patients who underwent transrectal ultrasound - guided prostate biopsy at our institutions and were orally administered prophylactic antibiotics (levofloxacin) were included. Two rectal preparations were performed: (1) adequate rectal preparation confirmed by digital rectal examination and transrectal ultrasound (Group A, n = 310) and (2) traditional rectal preparation (Group B, n = 200). All patient characteristics were recorded. A logistic regression model was used to assess the effects of the two different rectal preparations on urosepsis, adjusted by patient characteristics. Results: There were a total of three and nine hospitalizations for urosepsis in Groups A and B, respectively. Differences in the demographic data between the two groups were insignificant. Logistic regression showed that adequate rectal preparation before biopsy significantly decreased the risk for urosepsis after biopsy (adjusted odds ratio: 0.2; 95% confidence interval: 0.05 - 0.78; P = 0.021). Conclusions: Adequate rectal preparation could significantly reduce hospitalizations for urosepsis within 1 month after transrectal ultrasound-guided prostate biopsy. The quality of rectal preparation should be evaluated before biopsy. If adequate rectal preparation is not achieved, postponing the biopsy and adjusting the rectal preparation regimen are suggested.

Tissue sulfomucin and sialomucin content in colon mucosa without intestinal transit subjected to intervention with Curcuma longa (curcumin)

Abstract Purpose: To measure the tissue sulfomucin and sialomucin content of the colon mucosa without fecal flow, subjected to intervention with curcumin, and the influence of the concentration used and the intervention time. Methods: Thirty-six rats were subjected to proximal right colostomy and distal mucous fistula. They were divided into two groups according to whether sacrifice was performed two or four weeks after the intervention. Each group was divided into three subgroups according to the enema applied daily: saline alone; curcumin at 50 mg/kg/day or curcumin at 200 mg/kg/day. Acid mucins were diagnosed using the Alcian blue technique. The mucin content was quantified by means of computer-assisted image analysis. The significance level of 5% was used throughout (p < 0.05). Results: There were dose-related increases in the quantities of sulfomucins in the animals subjected to interventions with curcumin, both after two weeks (p < 0.00001) and after four weeks (p < 0.00001). There were increases in sialomucin quantity that were concentration-related (p < 0.00001) and time-related (p < 0.00001). Conclusion: Curcumin enemas increase the quantity of acid mucins in the intestinal flow in the excluded colon, with dose and time dependency.

Claudin-3 and occludin content in the glands of colonic mucosa devoid from fecal stream submitted to topical intervention with oil extract of Curcuma longa

Abstract Purpose: To evaluate the inflammatory intensity and measure the tissue content of the proteins claudin-3 and occludin in the colonic mucosa without fecal stream submit to intervention with curcumin. Methods: Thirty-six rats were submitted to a proximal colostomy and a distal mucous fistula and divided into two groups according to sacrifice to be performed two or four weeks. Each group was divided into three subgroups according daily application of enemas containing saline, curcumin at 50 mg/kg/day or 200 mg/kg/day. Colitis was diagnosed by histological analysis. Claudin-3 and occludin were determined by immunohistochemistry. The tissue content of claudin-3 and occludin were quantified by computer-assisted image analysis. Mann-Whitney, Student t and ANOVA tests were used to analyze the results establishing the level of significance of 5% for both (p<0.05). Results: Curcumin at both concentrations reduces the inflammation and preserves the tissue content of the proteins claudin-3 and occludin, which was related to the concentration used and to the time of the intervention. Conclusion: The application of enemas with curcumin reduces inflammation and preserves the tissue content of the proteins claudin-3 and occludin in the colonic mucosa devoid from the fecal stream.

Tissue content of sulfomucins and sialomucins in the colonic mucosa, without fecal stream, undergoing daily intervention with sucralfate

PURPOSE: To measure the content of acidic mucin, sialomucin, and sulfomucins in the colonic mucosa without fecal stream submit to intervention with sucralfate (SCF). METHODS: Thirty-six rats were submitted to a right colostomy and a distal mucous fistula and divided into two groups according to sacrifice to be performed two or four weeks. Each group was divided into three subgroups according daily application of enemas containing saline, SCF at 1.0 g/kg/day or 2.0 g/kg/day. Colitis was diagnosed by histological analysis. Acid mucins were determined with the Alcian-Blue and sulfomucin and sialomucin by high iron diamine-alcian blue (HID-AB) techniques. The mucins were quantified by computer-assisted image analysis. Mann-Whitney and ANOVA tests were used to analyze the results establishing the level of significance of 5% for both (p<0.05). RESULTS: SCF enemas decreased the inflammation score and was related to the concentration used and time of the intervention. SCF at both concentrations increased the content of acid mucin, which was related to the concentration used and to the improvement in the inflammatory score. There was an increase in the content of sulfomucins and sialomucins in SCF groups. SCF increased sulfomucins from 2 weeks of intervention, which was not related to the dose or time of application. The increase in sialomucin content was related to the time and dose used in the intervention. CONCLUSION: Sucralfate increased the content of acidic mucins, primarily at the expense of sialomucin, which was affected by the dose and time of intervention. .

Evaluation of the application of enemas containing sucralfate in tissue content of neutral and acid mucins in experimental model of diversion colitis

PURPOSE: To evaluate the effects of sucralfate on tissue content of neutral and acids mucins in rats with diversion colitis. METHODS: Thirty-six rats were submitted to a proximal right colostomy and a distal mucous fistula. They were divided into two groups according to sacrifice to be performed two or four weeks after intervention. Each group was divided into three subgroups according daily application of enemas containing saline, sucralfate at 1.0 g/kg/day or 2.0 g/kg/day. Colitis was diagnosed by histological analysis and neutral and acid mucins by Periodic Acid Schiff and Alcian Blue techniques, respectively. The contents of mucins were quantified by computer-assisted image analysis. Student's t paired and ANOVA test were used to compare the contents of both types of mucins among groups, and to verify the variance with time, establishing level of signification of 5% for both (p<0.05). RESULTS: Enemas containing sucralfate improves the inflammation and increases the tissue contents of neutral and acid mucins. The content of neutral mucins does not change with the time or concentration of sucralfate used, while acid mucins increases with concentration and time of intervention. CONCLUSIONS: Sucralfate enemas improve the inflammatory process and increase the tissue content of neutral and acid mucins in colon without fecal stream. .

Evacuación del meconiointestinal para mejorar tolerancia alimentaria en prematuro de muy bajo peso (protocolo Emita) / Meconium evacuation to improve feeding tolerance in very low birth weight preterm infants (Emita protocol)

Se ha descrito que la tolerancia alimentaria en el extremo prematuro se asocia a una precoz eliminación de meconio. Estudios prospectivos, randomizados o con controles históricos de estimulación de evacuación de meconio reportan diferentes resultados. El objetivo de este estudio fue evaluar el uso sistemático de enemas que aceleren la evacuación de meconio, y por ende la tolerancia alimentaria. Pacientes y Método: Estudio controlado, aleatorizado y multicéntrico que evaluó el uso de enemas de solución fisiológica con glicerina (0,8 ml de glicerina + 3 ml de solución fisiológica o 1 ml de glicerina + 5 ml de solución fisiológica según peso al nacer menor o mayor de 800 g, respectivamente) versus simulación, iniciado en los primeras 96 h de vida, en prematuros con peso al nacimiento entre 500 y 1.250 g. Se registraron antecedentes maternos (parto prematuro, infección ovular, síndrome hipertensivo del embarazo, administración de sulfato de magnesio, y corticoides prenatales, doppler fetal alterado, tipo de parto, sexo, peso y edad gestacional, evaluación de apgar y necesidad de ventilación asistida y oxígenoterapia) y nutricionales (edad al alcanzar volúmenes de alimentación de 100 ml//kg/día y alimentación enteral completa, edad para eliminar meconio, número de días en nutrición parenteral, peso a los 28 días, volúmenes semanales de leche materna y fórmula de prematuros). Resultados: En 101 sujetos incluidos en el estudio, no se obtienen diferencias significativas en la variable principal de edad para alcanzar el aporte enteral total o los 100 ml por kg por día. Tampoco se observan diferencias en las variables secundarias: número de episodios de sepsis tardías con o sin hemocultivo positivo, hiperbilirrubinemia, enterocolitis necrotizante o hemorragia intracraneana...

Introduction: It has been reported that feeding tolerance in preterm infants is associated with an early passage of meconium. Prospective, randomized or historical control studies that stimulate meconium evacuation have reported varied results. This study was intented to evaluate the use of enemas to speed up meconium evacuation, facilitating feeding tolerance. Patients and Method: A controlled multicenter randomized trial that evaluated the use of physiological saline enemas with glycerol (0.8 ml glycerol + 3 ml saline or 1 ml glycerol + 5 ml saline depending on babies weighing less or more than 800 g at birth, respectively) versus simulation. This procedure was performed in the first 96 hours of life in infants with birth weight between 500 and 1,250 g. Maternal (preterm delivery, clinical chorioamnionitis, gestational hypertension, administration of magnesium sulfate and prenatal corticosteroids, fetal Doppler altered, type of delivery, gender, weight and gestational age, assessment of Apgar and need for assisted ventilation and oxygenotherapy) and nutritional history (age when feeding volumes of 100 ml/kg/day and full enteral feeding were reached, age to remove meconium, number of days on parenteral nutrition, weight at 28 days, weekly volumes of breast milk and preterm formula) were described. Results: No significant differences were obtained regarding the age to reach full enteral intake or 100 ml/kg/day were found among the 101 patients in the study. Also, no differences in the following secondary variables are observed: number of episodes of late sepsis with or without positive blood culture, hyperbilirubinemia, necrotizing enterocolitis and intraventricular hemorrhage...

Complications of Transrectal Ultrasound-Guided Prostate Biopsy: Impact of Prebiopsy Enema

PURPOSE: Transrectal ultrasound (TRUS)-guided biopsy of the prostate is usually safe. However, some patients are hospitalized owing to complications from TRUS biopsy. We identified the risk factors for complications and effective preventive measures for treating complications after TRUS biopsy. MATERIALS AND METHODS: Medical records and radiological images of 1,083 patients who underwent TRUS biopsy of the prostate over 10 years in Gyeongsang National University Hospital were examined retrospectively to investigate the correlation between complications after TRUS biopsy and preventive antibiotics, prebiopsy enema, number of biopsy cores, and pathological findings. RESULTS: Complications occurred in 69 patients (6.4%). The complication rates of the 1,008 patients who received antibiotics and the 75 patients who did not were 6.3% and 8.0%, respectively (p=0.469). Complication rates of the pre-biopsy enema group (n=658) and the group without prebiopsy enema (n=425) were 4.7% and 8.9%, respectively (p=0.007). Complication rates of the 6-core biopsy group (n=41) and the 12-core biopsy group (n=955) were 7.3% and 6.3%, respectively (p=0.891). Complication rates of the prostate cancer group (n=306) and the no prostate cancer group (n=713) were 6.2% and 6.6%, respectively (p=0.740). CONCLUSIONS: A prebiopsy enema was associated with a reduced risk of complications after TRUS biopsy. Preventive antibiotics, number of biopsy cores, and pathological findings did not significantly influence the complication rate.

Al-Amal Al-Ehteqan [the enemata] an ancient way of complementary treatment

Enemata are the liquid preparations that are injected into the rectum and colon through anus. They are either intended to be returned or to be retained into the colon. Enema is an excellent treatment for removing superfluous matter from the bowels. It is the treatment of choice for intestinal colic. That's why it is called as Moalijah Al Fazilah [the Superfluous Therapy]. It allays pain and inflammation of the bowels, kidney, bladder and other pelvic organs. Enemas have been in practice from ancient time and helped to cure a lot of disorders like constipation, poisoning, acute headache, flu, common cold, meningitis, measles and many more. On the other hand enemas were largely practiced for many other therapeutic and diagnostic purposes also. Classical literature of Unani medicine describes enema in a scientific manner. Our ancestors had an ensuring experience in treating various kinds of disorders by this simple way. Unani scholars have mentioned even adiposgenous [Fattening] and aphrodisiac enemata. As per the necessities in the medical field enema has many types according to their mode of actions

Impactación fecal / Fecal impactation

Introducción: La Impactación fecal (I.F.) es la acumulación de materia fecal dura fundamentalmente en el recto, que no puede evacuarse voluntariamente. Es más común en el anciano y en personas debilitadas, inactivas, o que usan drogas por enfermedades psiquiátricas. Objetivo: Evaluar una serie consecutiva de pacientes con I.F., discutir su etiopatogenia y los resultados del tratamiento. Pacientes y método: Entre Enero 2006 y Diciembre 2008, de 26862 internaciones en el Sanatorio Trinidad Dupuytren de la Ciudad de Buenos Aires, 87 (0.32%) fueron por I.F. Mujeres 54 (62%), edad promedio 75 (rango 95-32) años. La I.F. fue baja (en el recto ó el rectosigma) en 50 (57.47%) pacientes y alta en 37 (42.53%). El diagnóstico se hizo con: examen semiológico y proctológico con instrumental rígido, Videocolonoscopía (VCC), radiología directa del abdomen, radiología contrastada del colon y tomografía abdominal computada (TC) según el caso. Resultados: Todos tenían factores condicionantes, más frecuentemente senectud (42.52%), trastornos neurológicos (20.69%), dolicocolon (9.19%) y megacolon chagásico (5.74%). Más del 90% se diagnosticaron con tacto rectal y endoscopía rígida. Las altas con VCC y ocasionalmente TC. Todos recibieron tratamiento médico (enemas tipo Murphy, laxantes y dieta), excepto 3 (3.45%) que fueron operados de emergencia por úlceras estercoráceas con peritonitis localizadas (operaciones tipo Hartmann). En 7 (8.3%) pacientes el tratamiento con enemas fue inefectivo, requiriendo extracción manual con anestesia: 4 y cirugía electiva: 3 (2 colostomías transversas y una cecostomía). Hubieron 9 (10.2%) complicaciones en los pacientes no operados (2 neumopatías, 5 fl ebitis y 2 infecciones urinarias) y 2 en los operados (absceso de pared y eventración). Estadía hospitalaria promedio: 11 (rango 5-45) días. Conclusión: El tratamiento con enemas por goteo, dieta y laxantes es de alta respuesta en la mayoría...

Introduction: Fecal impaction (F.I.) is the accumulation of hard feces, mainly in the rectum, that cannot be voluntarily expelled. It is more common in the elderly and in debilitated, or inactive persons, and those who use drugs for mental diseases. Objective: To assess a consecutive series of patients with con F.I., and discuss the etiopathology, and results of treatment. Patients and Methods: Between January 2006 and December 2008, from 26862 admissions in the Sanatorio Trinidad Dupuytren of Buenos Aires, 87 (0.32%) were for (F.I.) Women 54 (62%), mean age 75 (range 95-32) years. F.I. was low (in rectum or rectosigmoid) in 50 (57.47%) patients, and high in 37 (42.53%). Diagnosis was done with: physical exam, rigid sigmoidoscopy, videocolonoscopy (VC), plain abdominal X-ray, contrast colon radiology, and abdominal computed tomography (CT), case dependent. Results: All patients had conditioning factors, more frequently old age (42.52%), neurological conditions (20.69%), dolicocolon (9.19%) and Chagasic megacolon (5.74%). More than 90% were diagnosed with rectal digital exam and rigid sigmoidoscopy. For those with high impaction VC and occasionally CT were used. All patients had medical treatment (Murphy enemas, laxatives, and diet), except for 3 (3.45%) who underwent emergency surgery for estercoracic ulcers with localized peritonitis (Hartmann type operations). Enemas were ineffective in 7 (8.3%) patients, requiring manual extraction under anesthesia: 4, and elective surgery: 3 (2 transverse colostomies and 1 cecostomy). There were 9 (10.2%) complications in non-operated patients (2 pneumonias, 5 phlebitis, and 2 urinary infections), and 2 in operated patients (abdominal wall abscess, and incisional hernia). Length of stay: 11 (range 5-45) days. Conclusion: Treatment with enemas, diet and laxatives is highly effective in most patients...

Eficacia de los medios diagnósticos en el cáncer colorrectal en pacientes geriátrico / Efficacy of diagnostic means of the colorrectal cancer in elder patients

Las enfermedades colorrectales constituyen un serio problema de salud por su alta incidencia. En Cuba esta enfermedad ocupa la 4ta en orden de frecuencia para una tasa de 17,1 x 100 000 habitantes. Nuestro objetivo fue determinar los medios diagnósticos más utilizados en el pesquisaje del cáncer colorrectal. Se realizó un estudio descriptivo, longitudinal y prospectivo en el Policlínico Carlos Verdugo. El universo estuvo conformado por 37 pacientes geriátricos que asistieron a la consulta de gastroenterología en el periodo comprendido de enero 2007 a diciembre 2008. Las variables empleadas fueron sexo, edad, síntomas, signos y medios diagnósticos. El sexo más afectado fue el femenino para un 54 por ciento, el grupo etáreo donde apareció la enfermedad con más frecuencia fue de 60 a 69 años. Los síntomas y signos que predominaron fueron las diarreas con flemas y sangre en 12 pacientes, el dolor abdominal en nueve casos y el cambio del hábito intestinal en ocho pacientes, así como la mucosa hipocoloreada en 22 pacientes y la masa tumoral palpable en seis casos. El medio diagnóstico más utilizado fue el ultrasonido con una positividad en (nueve casos), seguido de las colonoscopia con una positividad de 33 pacientes y de ellos el colon por enema con una positividad de 31 casos.

Colorrectal diseases are a serious health problem because of its high incidence. In Cuba this disease is at the 4 th place in frequency order with a rate of 17,1 x 100 000 inhabitants. The objective of our investigation was determining the most used diagnostic means in the colorrectal cancer testing. We carried out a descriptive, longitudinal and prospective study at the Policlinic Carlos Verdugo. The universe was formed by 37 elder patients assisting the gastroenterology consultation in the period from january 2007 to december 2008. The variables used were genre, age, symptoms, signs and diagnostic means. Among the main results we found that the most affected genre was the female one with 54 percent, the age group where the disease was more frequent was the group of 60-69 years old persons. The predominant symptoms and signs were diarrhea with phlegm and blood in 12 patients, abdominal pain in 9 cases and intestinal habits change in 8 patients, and also hypocolored mucosa in 22 patients and palpable tumor mass in 6 cases. The most used diagnostic mean was ultrasound with positivity in 9 cases, followed by colonoscopy with a positivity of 33 patients, among them colon by enema with a positivity of 31 cases.

Cáncer del ángulo esplénico del colon: presentación de un caso / Cancer of the colon spleen angle: presentation of a case

El cáncer de colon es actualmente un importante problema de salud pública en los países desarrollados. Es el cuarto cáncer más frecuente en el mundo. Reportamos un caso de una paciente femenina, de 65 años de edad, raza negra, que acude a la consulta por presentar trastornos dispépticos como único síntoma, sin factores de riesgo conocido. Se le indicó un colon por enema, en el que se observó un estrechamiento distal al ángulo esplénico del colon en la misma zona de la estrechez fisiológica a ese nivel. Se le realizó colonoscopia que diagnostica: tumor de colon izquierdo próximo al ángulo esplénico. Se operó y se le realizó la resección segmentaria de ángulo esplénico, así como biopsia. Anatomía patológica informa adenocarcinoma del colon bien diferenciado.

The colon cancer is currently an important public health problem in developed countries. It is the fourth most common cancer in the world. We report the case of a 65-years-old, black, female patient, assisting our consultation with dyspeptic disturbances as the unique symptom, without known risk factors. We indicated a colon by enema and a distal narrowing was observed at the colon spleen angle, at the same zone of the physiologic narrowing at that level. A colonoscopy was carried out diagnosing a left colon tumor near the spleen angle. It was operated with segmental resection of the spleen angle and a biopsy was made. Pathologic anatomy informed a well-differentiated colon adenocarcinoma.

Comparison of prophylactic and therapeutic use of short-chain fatty acid enemas in diversion colitis: a study in Wistar rats

OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after post-operative day 40). The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006) and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy.

Chronic abdominal pain: imaging of bowel

A 70-year-old-man was evaluated as an outpatient for chronic abdominal pain for the last two years. The pain was intermittent and not severe enough for him to seek immediate medical attention. There was no history of vomiting, abdomen distension, or of similar episodes in the past. He gave no history of any change in his bowel habits. There was no significant past medical history. On examination, his vital signs were stable. Abdominal examination was normal. An upper gastrointestinal series with small-bowel follow-through and a double contrast barium enema was performed, which clinched the diagnosis [Figures 1 and 2]. What is your diagnosis?

The Malone Antegrade Continence Enema (MACE) principle in children: is it important if the conduit is implanted in the left or the right colon?

OBJECTIVE: The aim of the study was to determine which was the optimal side for the conduit to be placed (right or left colon) for antegrade continence enema implantation. MATERIALS AND METHODS: Between July 1999 and March 2006, 31 patients underwent the construction of a catheterizable conduit using the Malone principle (MACE) In 22 cases the conduit was re-implanted in the right colon and in 9 cases in the left colon. There were 20 male patients and 11 female patients, with a mean age of 10.23 years. The follow-up period varied from 3 from 83 months (average 25 months). Right and left implantation of the conduit in the colon were compared with regards to the presence of complications, volume of the solution utilized, frequency of colonic lavage, time needed for performing the enema, and degree of satisfaction. RESULTS: One patient with the conduit in the right colon, using the appendix, lost the mechanism after two month follow-up. Thirty patients remain clean and are all capable of performing self-catheterization. No statistically significant differences were found between the groups regarding the variables studied: complications (p = 1.000), solution volume (p = 0.996), time required (p = 0.790) and patient's rating (p = 0.670). The lavage frequency required for patients with the conduit in the right colon may be lower. CONCLUSION: The MACE principle was considered effective for treating fecal retention and leaks, independent of the implantation site. The success of this surgery appears to be directly related to the patient's motivation and not to the technique utilized.

Reversão de intussuscepções intestinais por meio de enema guiado por ultra-sonografia: descrição de três casos / Ultrasound-guided hydrostatic reduction of intestinal intussusception: description of three cases

Com o objetivo de divulgar a técnica de reversão hidrostática da intussuscepção intestinal, guiada por ultra-sonografia, são descritos três casos do diagnóstico confirmado da afecção, que foram submetidos à reversão por meio dessa técnica. Nos três casos a reversão foi atingida com sucesso, sem complicações. Um paciente apresentou recidiva da invaginação após oito dias do tratamento, sendo submetido à correção cirúrgica. A técnica de reversão hidrostática de intussuscepção intestinal guiada por ultra-som pode ser utilizada no lugar do enema opaco convencional apresentando-se como um método pouco invasivo, seguro, com altos índices de sucesso e poucas complicações.

A randomized double-blind controlled trial comparing two forms of enema for flexible sigmoidoscopy.

OBJECTIVE: To compare bowel preparation quality and patient tolerance of two common enema solutions for flexible sigmoidoscopy. MATERIAL AND METHOD: Three hundred adults were randomized to receive a hypertonic sodium chloride or hypertonic sodium phosphate enema regime, each consisting of two enemas administered 60 and 30 min before the procedure. Patients completed surveys on preparation comfort. Patients and endoscopist were blinded to the preparation used During the procedure, the endoscopist took pictures of the mucosa and intraluminal content. All pictures were later evaluated by a single doctor who graded the quality of the preparation. RESULTS: There were no serious complications during or following the procedures. The preparation quality was rated as excellent or good by 76.9% of the hypertonic sodium chloride group and 72.9% of the hypertonic sodium phosphate group (p = 0.423). The hypertonic sodium chloride enema was associated with more abdominal discomfort (p = 0.018). CONCLUSION: Both enemas were safe for all patients with no statistical difference between the qualities of the two bowel preparations. Both preparations performed their bowel-cleaning function well and were suitable for the preparation of patients before flexible sigmoidoscopy. The less expensive hypertonic sodium chloride solution may be an option for hospitals where budgetary considerations are important.

Experimental antegrade enema: effects on water, electrolyte and acid-base balances with different solutions

PURPOSE: To study the effects on the water, electrolyte, and acid-base balances in rabbits submitted to antegrade enema with different solutions through appendicostomy. METHODS: Forty male New Zealand rabbits were submitted to appendicostomy, and distributed in 4 groups, according to the antegrade enema solution: PEG group, polyethylene glycol electrolyte solution (n=10); ISS group, isotonic saline solution (n=10); GS group, glycerin solution (n=10); SPS group, sodium phosphate solution (n=10). After being weighed, arterial blood gas analysis, red blood count, creatinine and electrolytes were measured at 4 times: preoperatively (T1); day 6 postop, before enema (T2); 4h after enema (T3); and 24h after T3 (T4). RESULTS: In PEG group occurred Na retention after 4h, causing alkalemia, sustained for 24h with HCO3 retention. In ISS group occurred isotonic water retention and hyperchloremic acidosis after 4h, which was partially compensated in 24h. GS group showed metabolic acidosis after 4h, compensated in 24h. In SPS group occurred hypernatremic dehydration, metabolic acidosis in 4h, and hypokalemia, hypocalcemia, hypomagnesemia, and metabolic alkalosis with partially compensated dehydration in 24h. CONCLUSIONS: All solutions used in this study caused minor alterations on water, electrolyte or acid-base balances. The most intense ones were caused by hypertonic sodium phosphate solution (SPS) and isotonic saline solution (ISS) and the least by polyethyleneglycol electrolyte solution (PEG) and glycerin solution 12 percent (GS).

OBJETIVO: Estudar os efeitos no equilíbrio hídrico, eletrolítico e ácido-base, do enema anterógrado com diferentes soluções em coelhos através de apendicostomia. MÉTODOS: 40 coelhos Nova Zelândia, machos, submetidos a apendicostomia, distribuídos em quatro grupos segundo a solução de enema: grupo PEG (n = 10) solução de polietilenoglicol com eletrólitos; grupo SF (n = 10) solução fisiológica; grupo SG (n = 10) solução glicerinada; grupo FS (n = 10) solução de fosfato de sódio. Realizou-se pesagem, gasometria arterial, série vermelha, creatinina e ionograma, em quatro tempos: TI (pré-operatório); T2 (6o PO antes do enema); T3 (4h após enema); T4 (24h após T3). RESULTADOS: No PEG ocorreu retenção de Na em 4h, com alcalemia por retenção de HCO3, mantida por 24h. No SF ocorreu retenção hídrica isotônica e acidose hiperclorêmica em 4h, resolvidos parcialmente com 24h. No SG ocorreu acidose metabólica hiperclorêmica em 4h, compensada com 24h. No FS ocorreu desidratação hipenatrêmica, acidose metabólica com ânion gap elevado em 4h, hipopotassemia, hipocalcemia, hipomagnesemia e alcalose metabólica com recuperação parcial da desidratação em 24h. CONCLUSÕES: Todas as soluções empregadas neste estudo causam alterações de pouca intensidade no equilíbrio hídrico, eletrolítico ou ácido-base. As mais intensas foram causadas pela solução de fosfato de sódio e solução fisiológica, e as menos intensas pela solução de polietilenoglicol com eletrólitos e solução glicerinada.
