RÉSUMÉ

BACKGROUND/AIMS: Although bisacodyl is a widely administered laxative, its underlying mechanism of action remains generally unknown. This study focuses on investigating the effects of bisacodyl on the human colon muscle contraction, and elucidating its mechanism of action. METHODS: Sigmoid colon muscle strips (20 longitudinal and 18 circular muscles) were obtained from 20 subjects who underwent colectomy for colon cancer. Isometric force measurements were calculated in response to electrical field stimulation (EFS, 0.3 milliseconds in trains of 10 Hz for 20 seconds, 150 V). Peak and nadir (tone) during and after EFS, were measured in a controlled state, and after sequential addition of bisacodyl (1 μM), atropine (1 μM), N-nitro-L-arginine (L-NNA, 100 μM), MRS2500 (1 μM), and tetrodotoxin (TTX, 1 μM) to the organ bath. RESULTS: Transient phasic contractions were observed during EFS, and after cessation of EFS. In the longitudinal muscles, nadir during EFS, and tone after EFS, significantly increased after addition of bisacodyl, and persisted after sequential addition of atropine, L-NNA, MRS2500, and TTX, indicating a direct action of bisacodyl on the smooth muscle. In the second experiment, pretreatment of TTX abolished EFS-induced phasic contractions. Although no phasic contraction was produced after perfusion of bisacodyl, tone was increased, thereby supporting evidence of a direct mechanism of action of bisacodyl on the colon smooth muscle. CONCLUSIONS: Bisacodyl increases the tone of longitudinal muscle in the human sigmoid colon through a direct action on the smooth muscle. Further study is warranted to investigate the neural mechanism of action of bisacodyl.

RÉSUMÉ

The effect of bisacodyl on the treatment of rats with slow transit constipation (STC) was studied. Forty-five female Wister rats were divided into control group, STC group, and STC bisacodyl group. The immunohistochemical method was used to determine interstitial cells of Cajal (ICC) and the expression of c-Kit protein. Body mass and the number of defecations were significantly decreased in the STC group compared with the control group on the 100th day after diphenoxylate administration, while dry weight of feces was significantly increased and the intestinal transit time was prolonged. There were significant differences in the number of defecations, dry weight of feces, and intestinal transit time among the three groups. The number of defecations was higher, dry weight of feces was lower, and intestinal transit time was shorter in the STC bisacodyl group compared to the STC group. In addition, ICC basement membrane dissolution occurred in the colon wall of the STC group. The connection between ICC and surrounding cells was destroyed, and the nucleus shrunken to different degrees. Moreover, c-Kit expression in the STC group was significantly lower than the control group. The connection between ICC and surrounding cells in the STC bisacodyl group was significantly stronger than the STC group, and the number of ICC and the expression of c-Kit were increased. Bisacodyl could reduce the severity of STC in rats by increasing the number of ICC and the expression of c-Kit.

RÉSUMÉ

Resumen: Introducción: Múltiples preparaciones intestinales se han utilizado en niños sometidos a una colonoscopia, con limitación variable debido a la aceptación, tolerancia y la limpieza adecuada. El objetivo del estudio fue comparar la tolerancia seguridad y eficacia de la preparación intestinal para colonoscopia de 1 día con PEG 3350 (polietilenglicol) (4 g/kg/día) + bisacodilo y el tratamiento con 2 días de preparación con PEG 3350 (2 g/kg/día) + bisacodilo en pacientes pediátricos. Métodos: Se realizó un ensayo clínico, aleatorizado y ciego. Se incluyeron pacientes de 2 a 18 años, que ameritaron colonoscopia en forma programada. Los pacientes se asignaron de manera aleatoria en dos grupos: 1 día de preparación con PEG 3350 4 g/kg/día + bisacodilo y 2 días de preparación con PEG 3350 2 g/kg/día + bisacodilo. Por medio de un cuestionario, exploración física y valoración endoscópica (escala de Boston), se determinó la tolerancia, seguridad y eficacia de las 2 preparaciones a evaluar. Se realizó una prueba t de Student para variables cuantitativas y χ2 para variables cualitativas. Resultados: No hubo diferencias significativas en las tasas de cumplimiento, los efectos adversos y la extensión de la evaluación colonoscópica. Conclusiones: La tolerancia y seguridad entre la preparación intestinal para colonoscopia de 1 día con PEG 3350 (polietilenglicol) (4 g/kg/día) + bisacodilo y la preparación de 2 días con PEG 3350 (2 g/kg/día) + bisacodilo fue semejante. La calidad de la limpieza fue buena en ambos grupos, siendo parcialmente más eficaz en el grupo de 1 día con PEG 3350 (polietilenglicol) (4 g/kg/día).


Abstract: Background: Multiple intestinal preparations have been used in children undergoing colonoscopy, with variable limitation due to acceptance, tolerance, and proper cleaning. The objective of this study was to compare the tolerability, safety and efficacy of the colonoscopy preparation with 1 day with PEG 3350 (poliethylenglycol) (4 g/kg/day) + bisacodyl compared to 2 days of preparation with PEG 3350 (2 g/kg/day) + bisacodyl in pediatric patients. Methods: A clinical, randomized, and blind trial was performed. Patients aged 2 to 18 years scheduled for colonoscopy were included. Patients were randomized into two groups: 1 day of preparation with PEG 3350 4 g/kg/day + bisacodyl and 2 days of preparation with PEG 3350 2 g/kg/day + bisacodyl. Through a questionnaire, physical examination and endoscopic evaluation (Boston scale), the tolerance, safety and efficacy of the 2 preparations to be evaluated were determined. Student's t test was performed for quantitative variables and χ2 for qualitative variables. Results: There were no significant differences in compliance rates, adverse effects, and extent of colonoscopic evaluation. Conclusions: Tolerance and safety between the intestinal preparation for 1-day colonoscopy with PEG 3350 (4 g/kg/day) + bisacodyl and the 2-day preparation with PEG 3350 (2 g/kg/day) + bisacodyl were similar. The quality of cleanliness was good in both groups, being partially more effective in the 1-day group with PEG 3350 (4 g/kg/day).

RÉSUMÉ

Constipation is a prevalent, often chronic, gastrointestinal motility disorder. Bisacodyl, a stimulant laxative, is widely used to treat constipation in adults and children. This drug is usually safe, but it has some side effects including diarrhea, abdominal pain, colitis, and proctitis. There have been reports that rectal administration of bisacodyl could cause injury to the rectal mucosa by mechanical and chemical mechanisms. However, there has been no report of severe proctitis with rectal ulcers in patients taking oral bisacodyl. In this report, we describe the case of an 80-year-old woman with severe rectal ulcers and proctitis after taking oral bisacodyl for several days, and review the literature.

RÉSUMÉ

Background - Colonoscopy is an important diagnostic and therapeutic procedure. Adequate bowel preparation is mandatory. Several regimens were discussed in the literature. Among the drugs which has recently used, polyethylene glycol is one of the most popular agents. Objectives - The aim of this study was to compare efficacy of three different methods for 1 day preparation before colonoscopy. Methods - This study included children with the range of ages (2-21) who had an indication of colonoscopy. Exclusion criteria were based on the history of previous surgery, parental disagreement, and patients who did not use preparation protocol. Three methods for bowel preparation were studied: 1- Polyethylene glycol only; 2- Polyethylene glycol and bisacodyl suppositories; 3- Polyethylene glycol plus normal saline enema. Boston Bowel Preparation Score was used for evaluation of preparation. SPSS version 16.0 (Chicago, IL, USA) were used for data analysis. Results - In this study 83 cases completed the bowel preparation completely. Acceptable bowel preparation was seen in 24 (85.71%), 36 (94.73%), and 14 (82.35%) of cases in PEG, PEG + bisacodyl, and PEG + normal saline enema groups respectively. PEG + bisacodyl suppositories was more effective than PEG + normal saline for the preparation of the first segment ( P=0.05). For second and third segment of colon, BPPS score was higher in PEG + bisacodyl suppositories compared to other regimens, but this difference was not statistically significant. Conclusion - There was no significant difference between 1 day colonoscopy regimens in terms of bowel preparation score. Lowest score was seen in PEG + enema group compared to other group.


Contexto - A colonoscopia é um procedimento diagnóstico e terapêutico importante. A preparação intestinal adequada é obrigatória. Vários esquemas são discutidos na literatura. Dentre as drogas que se têm usado recentemente, o polietilenoglicol é um dos agentes mais utilizados. Objetivo - O objetivo deste estudo foi comparar a eficácia de três métodos diferentes para a preparação feita 1 dia antes de colonoscopia. Métodos - Este estudo incluiu crianças com a gama de idades entre 2 e 21 anos, que tinham indicação de colonoscopia. Os critérios de exclusão foram baseados em história da cirurgia anterior, não aprovação dos pais e pacientes que não utilizaram o protocolo de preparação. Três métodos para a preparação do intestino foram estudados: 1-polietilenoglicol; 2 - polietilenoglicol e bisacodil supositórios; 3 - polietilenoglicol e enema de solução salina. O escore de Boston para preparação intestinal foi usado para a avaliação e os dados foram analisados pelo SPSS versão 16.0 (Chicago, Il, USA). Resultados - Um total de 83 pacientes concluiu completamente o preparo intestinal. Houve preparo aceitável em 24 (85,71%), 36 (94,73%) e 14 (82,35%) dos casos, nos grupos PEG, PEG + bisacodil e PEG + enema salino, respectivamente. PEG + bisacodil supositórios foi mais eficaz do que a PEG + solução salina para a preparação do primeiro segmento ( P=0,05). Para segundo e terceiro segmento do cólon, a pontuação de BPPS foi maior no grupo PEG + bisacodil supositórios em comparação com outros regimes, mas essa diferença não foi estatisticamente significativa. Conclusão - Não houve nenhuma diferença significativa entre os regimes de preparo para colonoscopia de um dia em termos de pontuação de preparação do intestino. A nota mais baixa foi vista no grupo PEG + enema em comparação com outros grupos.

RÉSUMÉ

Based on published guidelines on the management of chronic constipation, secondary causes should be excluded and then patients should be told to increase their dietary fiber intake to 20-25 g per day. If these measures do not improve the symptoms, conventional laxatives are generally the next choice. Although there is limited evidence for the efficacy of these older laxatives due to a lack of well-designed clinical trials, most clinicians agree that they are effective at relieving the symptoms of constipation. Conventional laxatives include bulk-forming, osmotic, and stimulant laxatives. Bulking laxatives consist of fiber such as psyllium, cellulose, and bran. Osmotic laxatives are classified into sugar-based laxatives and polyethylene glycol. Bisacodyl and sodium picosulfate are stimulant laxatives. Understanding their mechanisms of action, efficacy, and side effects might improve the quality of life of patients suffering from chronic constipation.

RÉSUMÉ

BACKGROUND/AIMS: Inpatient status can cause inadequate bowel preparation. The majority of previous studies regarding bowel preparation have focused on comparing the effects of different purgative regimens in outpatients. However, data on bowel preparation for inpatients are lacking. The aim of this study was to investigate whether bisacodyl plus polyethylene glycol (PEG) can improve bowel preparation in hospitalized patients. METHODS: A prospective, randomized and observer-blind study was performed. A total of 196 hospitalized patients undergoing colonoscopy were randomized to receive 4 L PEG (PEG only group) or 4 L PEG+bisacodyl 10 mg (bisacodyl added group). The adequacy of bowel preparation was scored using the Ottawa bowel preparation scale. RESULTS: One hundred and eighty-three subjects completed the study; 96 in the bisacodyl added group and 87 in the PEG only group. There were no significant differences between the bisacodyl added group and the PEG only group with respect to the score of bowel cleansing (3.59+/-2.81 vs. 3.82+/-3.03, p=0.607), quality of bowel cleansing (adequate preparation 89.6% vs. 85.1%, p=0.380), and overall adverse events (66.7% vs. 52.9%, p=0.057). However, a larger proportion of patients in the PEG only group were able to ingest the entire solution as prescribed than in the bisacodyl added group (98.9% vs. 75.0%, p<0.001). CONCLUSIONS: In hospitalized patients, the quality of bowel preparation did not differ depending on whether bisacodyl is added or not. In addition, patient compliance based on consumption of cleansing agent was better in the PEG only group.

RÉSUMÉ

CONTEXT: Colonoscopy is currently the gold standard method to examine the colon, the rectum and the terminal ileum. In order to perform the colonoscopy, it is necessary to clean the bowel and use medications that are generally poorly tolerated by the patients. OBJECTIVE: Compare the tolerability, acceptability, safety and efficacy of two solutions used for intestinal preparation for a colonoscopy. METHODS: One hundred patients matched for sex and age were prospective randomized into two groups. Polyethylene glycol group received bisacodyl 10 mg plus 1 L of polyethylene glycol the night before and 1 L on the day of the exam. Mannitol group received bisacodyl 20 mg the day before and 1 L of a 10% mannitol solution on the day of the exam. The diet was the same for both groups. Tolerability and acceptability were measured using previously validated questionnaires. In terms of safety, variations in vital signs before and after the preparation were recorded, in addition to any complications. The quality of the preparation was graded based on the Boston and Ottawa scales. RESULTS: Ninety-six percent (96%) completed the study. As for tolerability, the mannitol preparation group exhibited a significantly higher frequency of nausea, vomiting, abdominal pain, and abdominal distension than polyethylene glycol group (P < 0.05). Acceptability was significantly better in polyethylene glycol group. The polyethylene glycol solution has also previously been shown to be safer than mannitol. No difference was observed in the quality of the preparation between the two preparation methods. CONCLUSIONS: The following conclusions can be made: polyethylene glycol solution had higher tolerability, acceptability, and safety than the mannitol and should be used instead of mannitol. Both preparation solutions have similar efficacy.


CONTEXTO: O exame de colonoscopia é atualmente o padrão-ouro para investigação do cólon e íleo terminal. Para sua realização há necessidade de limpeza do cólon com soluções que, em geral, são mal toleradas pelos pacientes. OBJETIVO: Comparar duas soluções de preparo intestinal para colonoscopia quanto à tolerabilidade, aceitabilidade, segurança e efetividade. MÉTODOS: Cem pacientes pareados por sexo e idade foram randomizados prospectivamente em dois grupos. O grupo polietilenoglicol recebeu bisacodil 10 mg + 1 litro de polietilenoglicol na véspera e 1 litro no dia do exame. O grupo manitol recebeu bisacodil 20 mg na véspera e 1 litro de manitol 10% no dia do exame. A dieta foi a mesma nos dois grupos. A tolerabilidade e aceitabilidade foram aferidas por questionários previamente validados. Quanto à segurança foram avaliados: variação de sinais vitais antes e após o preparo e complicações, além de quaisquer sinais de complicação. A qualidade do preparo foi graduada através das escalas de Boston e Ottawa. RESULTADOS: Noventa e seis pacientes (96%) completaram o estudo. Quanto à tolerabilidade o grupo manitol apresentou manifestação significativamente maior de náusea, vômito, dor abdominal e distensão abdominal do que o grupo polietilenoglicol (P<0,05). Aceitabilidade foi significativamente melhor com o grupo polietilenoglicol. O grupo polietilenoglicol também se mostrou mais seguro. Não se observou diferença na qualidade do preparo entre os métodos. CONCLUSÕES: A solução de polietilenoglicol apresentou melhor tolerabilidade, aceitabilidade e segurança e deve ser usada ao invés da solução de manitol. Ambas as soluções são semelhantes em eficácia.

RÉSUMÉ

Constipation is one of the most common symptoms that a child visits pediatrician. The general approach to the child with functional constipation includes the following steps; disimpaction, maintenance and withdrawal of medication. There are many drugs which can be applied to children; osmotic agents (lactulose, sorbitol, magnesium hydroxide/citrate, polyethylene glycol with/without electrolytes, sodium phosphate, glycerin), stimulants (senna, bisacodyl, caster oil), lubricant (mineral oil), bulking agent (psyllium, cellulose, glucomannan). At each stage of treatment, one or some of these drug can be applied to the purpose. The author tries to summarize recent studies on drugs for constipation in child, and finally introduces new dugs for constipation which is under investigation.

RÉSUMÉ

BACKGROUND/AIMS: The aim of the study was to prospectively compare low-volume PEG plus 20 mg bisacodyl with the standard 4 L PEG with regards to the adequacy of bowel preparation, patient compliance and the side effects. METHODS: From September 2007 to January 2008, 59 patients who had previously undergone screening colonoscopy with 4 L PEG and had been diagnosed with colonic polyps were admitted for polypectomy. The colonoscopists, who were unaware of the preparation that was administered, evaluated the adequacy of the bowel cleansing. Detailed questionnaires were also used to assess patient compliance, the difficulty of bowel preparation, side effects and patient preference. RESULTS: The physician's evaluation of the colon cleansing showed better adequacy with 4 L PEG than with 2 L PEG plus bisacodyl (p<0.05). There was no difference in patient compliance between the 2 bowel preps. The patients in the 2 L PEG plus bisacodyl group tolerated the bowel preparation more easily than the patients in the 4 L PEG (81.4% vs. 15.3%, respectively). Moreover, the scores of the visual analog scale for the difficulty of bowel preparation were 5.8+/-2.3 in the 4 L PEG group and 3.2+/-1.9 in the 2 L PEG plus bisacodyl (p<0.01). The majority (89.8%) of the patients preferred 2 L PEG plus bisacodyl (p<0.001). The 2 L PEG plus bisacodyl group revealed less nausea, vomiting and sleep discomfort (p<0.05), but they had more abdominal pain (p<0.01). CONCLUSIONS: 2 L PEG plus bisacodyl is not as effective as the standard 4 L PEG for colon cleansing. However, 2 L PEG plus bisacodyl can be used for patients who have difficulty drinking a large amount of PEG.

RÉSUMÉ

O presente estudo comparou dois medicamentos, consagrados no mercado, utilizados no tratamento da constipação intestinal. São eles: docusato sódico + bisacodil (Humectol D) e bisacodil (Dulcolax). O número de pacientes avaliados foi de 91. A demografia da população do estudo foi dominantemente homogênea para os dois grupos de medicamentos, apesar de alguns dados, como idade e sexo, apresentarem uma distribuição distinta. Os resultados referentes à tolerabilidade foram de bons a excelentes em ambos os grupos de tratamento. Com relação à eficácia dos medicamentos, o docusato sódico + bisacodil (Humectol D) e o bisacodil (Dulcolax) demonstraram-se equivalentes no tratamento de constipações intestinais. Diante dos resultados obtidos nesse estudo clínico ficaram demonstradas a excelente eficácia e tolerabilidade do docusato sódico + bisacodil (Humectol D).

RÉSUMÉ

BACKGROUND/AIMS: This study compared the efficacy and patient's tolerance between those given a divided dose of a polyethylene glycol solution (PEG) and those given a stimulant laxative plus a reduced dose of PEG. METHODS: 190 consecutive patients for colon cleasing were randomized into 3 groups. In group A, 2 L of PEG was administered on the evening prior to the colonoscopy followed by 2 L of the same solution on the morning of colonoscopy. In group B, 2 L of PEG was administered in the morning only. In group C, 2 bisacodyl tablets (10 mg) were administered on the evening prior to colonoscopy and 2 L of PEG was administered in the morning. The patients completed a questionnaire to assess their tolerance to the bowel preparation before the colonoscopy. The endoscopists scored the adequacy of the bowel preparation using the Ottawa scale along with their satisfaction with the quality of the procedure. RESULTS: While 4 patients (6.7%) could not completely take the recommended dose in group A, all patients in groups B and C could take the recommended dose (p=0.012). The patients in Group B had a better tolerance and fewer side effects than those in Group A (p=0.01). A higher adequacy of bowel preparation was observed in group A than in group B (p=0.000) and there appeared to be a higher adequacy of bowel preparation in Group C than in Group B (p=0.06). CONCLUSIONS: The 2 L PEG solution only does not appear to be as effective as a bowel cleansing agent for colonoscopy compared with the divided 4 L PEG solution. No statistical difference in the side effects and efficacy was observed between the divided 4 L PEG solution and the combination of bisacodyl 10 mg with 2 L of a PEG solution.

RÉSUMÉ

PURPOSE: This study was undertaken to determine whether a mechanical bowel preparation with 90 ml of sodium phosphate (NaP) solution (Group II) increased the acceptability of bowel preparation and reduced discomfort compared with 2 liters of polyethylene glycol (PEG) combined with a bisacodyl 20 mg (Group I). METHODS: We conducted a prospective, randomized, single-blinded study. Forty-four patients undergoing elective colorectal surgery in the National Health Insurance Corporation Ilsan Hospital from March 2002 to November 2002 were included in this study. We assessed the patients' tolerance and cleansing ability, as well as the surgeon's satisfaction, by using a structured questionnaire. Postoperative complications were also evaluated. RESULTS: Patient tolerance to NaP was higher than it was to PEG (P=0.034). The cleansing ability and the surgeon's satisfaction were not different between the two groups (P=0.217, P=0.349). There is no significant postoperative complication except for 1 case of wound infection in both group. CONCLUSIONS: Both oral solutions proved to be equally effective and safe. However, patient tolerance to the small volume of NaP demonstrated a clear advantage over the traditional PEG solution.

RÉSUMÉ

Näo há um preparo intestinal uniforme para a realizaçäo da colonoscopia que seja recomendado para as diversas faixas etárias da criança, do lactente ao adolescente. Ao contrário do paciente adulto, o procedimento é geralmente realizado com anestesia geral ou sedaçäo profunda. Assim, o jejum oral necessário após a ingestäo do laxante retarda o início do exame. Os autores avaliaram a eficácia de preparo com bisacodil eenema fosfatado em estudo aberto e prospectivo em 17 crianças e adolescentes de ambos os sexos durante um período de 3 meses. A idade dos pacientes variou de 10 meses a 15 anos e 11 meses (mediana =5 anos e 2 meses), sendo 53 por sento do sexo masculino e 47 porcento do feminino. Foi utilizado bisacodil 5mg ou 10mg durante dois dias anteriores ao exame associado a 64ml ou 128ml de soluçäo fosfatada por via retal no diado exame em crianças menores e maiores de 5 anos, respectivamente. preparo excelente foi observado em 53 por cento, bom em 29 por cento e ruim em 18 por cento. Os dados sugerem que o preparo foi mais eficiente em crianças menores de 5 anos. os autores concluem que o preparo foi adequado em 82 por cento dos casos, podendo ser recomendado em crianças menores de 5 anos de idade

RÉSUMÉ

Realizamos 2000 colonoscopias ambulatoriais de dezembro de 1994 a maio de 1998. Na véspera, o preparo consistiu de dieta sem resíduos e quatro comprimidos de bisacodil às 19 horas. Para a manhä do dia do exame, orientamos o paciente diluir 120ml de lactulose em água ou suco de laranja coado até obter um litro de soluçäo e ingerí-la em uma hora, seis horas antes do início do procedimento endoscópico. Além disso, deveriam beber água ou chá à vontade até o momento do mesmo. As principais indicaçöes foram de dor abdominal, diarréia, enterorragia, obstipaçäo e pesquisa de tumores. Consideramos o resultado como Bom em 84, 85 por cento dos casos, Regular em 9,2 por cento e Ruim em 5,9 por cento. Ocorreu intolerância ao esquema em 3,35 por cento, quando os pacientes referiram vômitos. Queixas de cólicas abdominais, em 9,75 por cento dos casos, ocorreram principalmente durante a noite, sendo creditadas ao bisacodil. Mesmo os doentes com estenose näo complicaram com obstruçäo. Concluímos que o preparo de cólon para colonoscopia com lactose é eficaz, podendo ser feito a nível domiciliar, com boa aceitaçäo e maior conforto para o paciente

RÉSUMÉ

Colon preparation using polyethylene glycol (PEGLEC) and combination of bisacodyl and magnesium sulphate was compared in 74 patients. Type of preparation did not influence patient discomfort. The quality of preparation was excellent with PEGLEC in 63.6% as compared to 41.6% with combination preparation. The completion rates were similar in both groups. Good preparation was linked with shorter procedure duration (p = 0.001) and greater depth of examination. No major side effects were noted with both preparations. To conclude, polyethylene glycol is recommended for screening of right colon while combination of bisacodyl and magnesium sulphate is a good and cheap preparation modality to screen the left colon.

RÉSUMÉ

PURPOSE: This study was undertaken to determine whether a mechanical bowel preparation with 2 liters polyethylene glycol solution combined with a Bisacodyl 20 mg (Group II) increases the acceptability of bowel preparation and reduces discomfort compared with 4 liters of polyethylene glycol solution (Group I). METHODS: We conducted a prospective randomized single-blinded study. Eighty patients undergoing an elective colorectal surgery in Severance hospital from April 1999 to September 1999 were included in this study. The patients' tolerance, cleansing ability and surgeon's satisfaction were assessed by a structured questionnaire. Postoperative complications were also evaluated. RESULTS: The patients' tolerance of the group II (2 liters polyethylene glycol solution combined with a Bisacodyl 20 mg) was better than that of the groups I (4 liters of polyethylene glycol solution). The cleaning ability and surgeon's satisfaction were not different between two groups (p=0.225, p=0.322). The incidence of postoperative complications was 2.3 percent in Group I and 2.7 percent in Group II. CONCLUSIONS: The mechanical bowel preparation with two liters of polyethylene glycol solution with a Bisacodyl 20 mg was more comfortable to patients and equally efficient compared with the mechanical bowel preparation with the 4 liters of polyethylene glycol solution regimen before elective colorectal surgery.

RÉSUMÉ

Desde o primeiro exame de fibrocolonoscopia em 1969, o continuo aperfeiçoamento das técnicas para a sua execuçäo bem como a perspectiva terapeutica sobre inumeras doenças do intestino grosso foram os responsáveis pela propagaçäo e popularizaçäo do método. O presente trabalho objetiva avaliar retrospectivamente os resultados da aplicaçäo da fibrocolonoscopia na disciplina de Coloproctologia do HCFMUSP no periodo de 1984 a 1995. Foram realizados 1715 exames com emprego do fibrocolonoscopio. Mais de 50 por cento dos doentes tinham idade entre a quinta e sétima decadas. A indicaçäo do exame foi de 37 por cento para os doentes que apresentavam alteraçöes do hábito intestinal ou perda de sangue as evacuaçöes, de 16 por cento para o seguimento dos doentes operados por cancer do intestino grosso e de 18 por cento para a investigaçäo da doença inflamatoria. Os exames foram realizados em regime ambulatorial em 90 por cento dos doentes. O preparo intestinal do tipo manitol expresso foi utilizado com sucesso em 97 por cento dos doentes. O resultado do exame foi normal em 728 (42,5 por cento) doentes. Polipos foram encontrados em 248 (14,5 por cento) doentes resultando em 376 polipectomias endoscopicas. Em 202 (11,8 por cento) doentes o diagnóstico foi tumor do intestino grosso. A molestia diverticular foi diagnosticada em 216 (12,6 por cento) doentes. Sindromes polipoides constituiram o diagnóstico em 53 (3,1 por cento) doentes e a ectasia vascular em 18 (1,1 por cento). A colonoscopia foi incompleta em 68 (3,9 por cento) ocasiöes. Nesta casuistica nao houve complicaçöes do tipo perfuraçäo ou sangramento nem quanto a sedaçäo e analgesia empregadas. Os autores concluem que o exame colonoscopio constitui método eficaz para o diagnóstico das afecçöes colorretais. A realizaçäo da fibrocolonoscopia enquanto método de diagnóstico e terapeutica (polipectomia) resultou em morbidade nula
