Bowel preparation for colonoscopy: is diet restriction necessary?Chang, Hung-Jou 02 August 2021 (has links)
Background: Bowel preparation is essential for quality colonoscopy. Although most bowel preparation regimens recommend dietary restriction for 24 to 48 hours before the procedure, the evidence for this is poor. Objectives: To establish whether dietary restriction during bowel preparation improves the quality of bowel preparation. Methods: A prospective single blind, randomised controlled pilot study. The dietary restriction (DR) group was instructed not to ingest high fibre foods for 48 hours prior to the use of a polyethylene glycol (PEG) bowel preparation. The non-dietary restriction (NDR) group was not given any dietary modification, but received instructions for the use of the PEG-based preparation solution. On the day of colonoscopy, the quality of the bowel effluent was assessed, and additional preparation given as necessary. The primary endpoint was quality of bowel cleansing using the Harefield Cleansing Scale during colonoscopy. The secondary endpoint was the need for additional bowel preparation and quantity of additional bowel preparation given prior to endoscopy. Data were analysed on an intention to treat basis. Results: Twenty-three participants were randomised to the intervention group and thirty-four to the control group. Patient demographics were similar in both groups. Dietary restriction did not influence the success rate of bowel preparation: 97% successful bowel preparation in the DR group, vs 91% successful bowel preparation in the NDR group (p=0.559). Additional bowel preparation requirement were similar in both groups: 35% in DR group vs 39% in NDR group (p=0.768). Mean amount of additional bowel preparation required was similar: 560 ml in the DR group vs 460 ml in the NDR group (p=0.633). Conclusion: The quality of bowel preparation was comparable in patients with and without dietary restrictions prior to colonoscopy. Non-restrictive diets prior to bowel preparation should be considered to increase compliance. The sample size of this pilot study prohibited definite statistical conclusions but demonstrated this to be a reasonable methodology for a larger study.

Efficacy Of Various Modes Of Bowel Preparation to Prevent Surgical Site Infection Following Elective Colorectal ResectionKoller, Sarah January 2016 (has links)
Purpose: Administration of a mechanical bowel preparation (MBP) has long been standard before colorectal surgery with the aim of preventing complications such as surgical site infection (SSI). Newer evidence suggests that MBP does not reduce the risk of infection and that oral antibiotic (OA) use may be important in reducing post-operative infectious complications, however, there is little evidence comparing MBP, OA, and combination preparations. Our goal was to determine the relationship between type of bowel preparation and SSI in patients undergoing elective colorectal resections Methods: All patients within the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database undergoing elective colorectal resections from 2012 to 2013 were identified. The primary outcomes of interest were: any post-operative SSI, wound SSI, and organ/space SSI. Secondary outcomes were anastomotic leak, post-operative ileus, cardiac complications, renal complications, death, unplanned readmission, and length of stay (LOS). Univariate models were used to compare frequencies of patient and surgical characteristics across types of bowel preparation, and propensity adjustment was used to study the relationship between type of bowel preparation and all outcomes of interest. Results: Among the study sample, 25.5% received no bowel preparation, 40.8% received MBP, 3.3% received OA, and 30.4% received OA+MBP. A total of 1,844 patients (9.5%) developed any type of post-operative SSI. 1,231 (6.4%) developed a wound SSI and 672 (3.5%) developed an organ/space SSI. MBP was not associated with a reduced risk of any type of SSI compared to no bowel preparation. Both OA and OA+MBP were significantly associated with a decreased risk of any SSI and wound SSI compared to both no preparation and compared to MBP. No differences were observed for any SSI or wound SSI between OA and OA+MBP. Compared to no preparation, OA+MBP was associated with a decreased risk of anastomotic leak and post-operative ileus. No differences were observed between MBP and OA, or between these preparation methods and no preparation, for these secondary outcomes. There were no significant associations between type of bowel preparation and cardiac or renal complications, mortality, or readmissions. Both OA and OA+MBP were associated with a reduction in LOS. Conclusion: These results suggest that a combination oral and mechanical bowel preparation may be most effective at preventing SSI after elective colorectal resection and that OA alone may also be effective. Future prospective studies comparing combination and OA preparations may be warranted to explore this relationship further. / Clinical Research and Translational Medicine

Patienters upplevelser av information om laxering inför datortomografi av tjocktarmen : En kvalitativ studieStengård, Johanna, Granholm, Madeleine January 2015 (has links)
Datortomografiundersökning av tjocktarmen har blivit en vanlig undersökning som utförs på röntgenavdelningar. Inför denna undersökning krävs förberedelser i form av laxering och födorestriktioner. Information till patienter inför denna undersökning är av stor vikt för förberedelsernas resultat och därmed även för en optimal undersökning. Syftet med denna studie var att beskriva om patienterna upplever att de fått tillräcklig information om laxeringsförberedelserna inför en DT-undersökning av tjocktarmen. Ett annat syfte med studien var att studera om patienterna förstått den information de fått. Tio patienter med en ålder mellan 62-81 år intervjuades efter DT-kolografiundersökningen på en röntgenavdelning i mellansverige under en period på två veckor. Det insamlade materialet analyserades sedan genom kvalitativ innehållsanalys. De intervjuade patienterna upplevde att informationen om förberedelserna inför DT-kolografiundersökningen var tillräcklig. Patienterna kunde ordagrant återberätta den information som de erhållit men det fanns en bristande förståelse av informationen som behandlade definitionen klar dryck och tillvägagångssättet med vissa mediciner. De flesta patienterna förstod syftet med de tarmförberedelser som utförs innan undersökningen. Studien visade att det fanns oklarheter i den skriftliga informationen inför DT-kolografiundersökningar som patienterna inte förstod, trots att de bedömde att informationen var tillräcklig. Genom att ta i beaktanden de brister i informationen om de tarmförberedelser som studiens resultat visar finns det förutsättning att undersökningens förberedelser och genomförande utförs på bästa möjliga sätt. / Computed tomography (CT) scan of the colon has become a common investigation in radiology departments. Prior to this examination preparation in form of purgation and food restrictions are required. Information to patients facing this examination are of great importance for the results of preparations and thus for optimal investigation. The aim of this studie was describe whether patients feel that they received sufficient information about the bowel preparations before a CT scan of the colon. Another purpose of the study was to see whether patients understood the information they receive before the examination. Ten patients with an age between 62-81 years were interviewed after the CT colography examination at the radiology department in a hospital in the middle of Sweden for a period of two weeks. The collected material was then analyzed by qualitative content analysis. The interviewed patients felt that information on preparations for the CT colonography examination was sufficient. Patients can literally retell the information received but there is a lack of understanding of the information that deals with the definition of clear liquids and the approach of certain medications. Most patients understood the purpose of the bowel preparations performance before the examination. The study showed that there were unclarities in the written infomrmation given before the CT colonography examination that the patients did not understand, even though they considered that the information was sufficient. By taking into considerations the lack of information about bowel preparation that the studies results show there are subject to examination, preparation and implementation is carried out in the best manner.

Efficacité des préparations coliques à doses fractionnées : une revue systématique et méta-analyse / Split-dose preparations are superior to day-before bowel cleansing regimens : a systematic revue and meta-analysisMartel, Miriam January 2016 (has links)
Introduction et objectifs: Les préparations coliques sont utilisées pour nettoyer le côlon avant de subir une coloscopie. Il existe plusieurs types de préparations coliques; celles-ci contiennent du polyéthylène glycol (PEG), du phosphate de sodium (NaP), du picosulfate (PICOS) ou une solution orale contenant du sulfate (OSS). L'administration en doses fractionnées est recommandées par plusieurs études randomisées mais une étude approfondie de la littérature n'a pas encore été effectuée. Notre objectifs est de déterminer l’efficacité des doses fractionnées comparativement à d’autres régimes posologiques, ainsi que le produit optimal et le volume le plus efficace.
Méthode: Nous avons procédé à une recension systématique de la littérature publiée entre janvier 1980 et mars 2014, à partir des bases de données MEDLINE, Embase, Scopus, CENTRAL et ISI Web of Knowledge. Une méta-analyse a été effectuée en incluant les études randomisées qui comparent des doses fractionnées à des doses administrées uniquement la veille de l’examen (non fractionnées). Ont été exclues les études portant sur une population pédiatrique ainsi que celles portant sur des patients hospitalisés ou atteints d’une affection intestinale inflammatoire. L’issue primaire consistait à déterminer la propreté du côlon. Les issues secondaires sont les effets indésirables,les issues procédurales, la volonté des patients à répéter la préparation colique et le temps requis pour reprendre leurs activités normales.
Résultats: Quarante-sept études randomisées répondant aux critères d’inclusion ont été répertoriées (n = 13 487 patients). La propreté du côlon était signficativement supérieure avec
les doses fractionnées [rapport de cotes (RC) = 2,51; intervalle de confiance à 95 % (IC) = (1,86-3,39)]. Le côlon était significativement plus propre avec les doses fractionnées de PEG [RC=2,60 (1,46-4,63)] de même qu’avec le NaP [RC=9,34 (2,12-41,11)] et le PICOS [RC=3,54 (1,95-6,45)] comparativement aux doses non fractionnées du même produit. La solution de 3 L ou plus de PEG en doses fractionnées a démontré une propreté supérieure à celle du PEG en doses fractionnées de faible volume [RC=1,89 (1,01-3,46)], mais seulement dans les analyses par intention de traitement. La volonté de répéter la préparation colique était supérieur chez les patients ayant reçu des doses fractionnées comparé aux doses non fractionnées [RC=1,90 (1,05-3,46)]; de même, que ceux ayant reçu <3 L de PEG en doses fractionnées comparativement à ceux qui ont PEG ≥ 3L en doses fractionnées [RC=4,95 (2,21-11,10)]. Les différences n’étaient pas significatives pour les autres issues. Conclusion: Les doses fractionnées augmentent le degré de propreté du côlon, en plus d’être le mode d’administration que les patients préfèrent, comparativement aux doses non fractionnées. D’autres études sont nécessaires afin d’évaluer L'OSS et les volumes réduits de PEG. / Abstract : Background & Aims
Bowel preparations are used before a colonoscopy to clean the bowel. There are different regimens of preparing the colon for colonoscopy, including polyethylene glycol (PEG), sodium phosphate (NaP), picosulfate (PICO), or oral sulfate solutions (OSS). Split-dose are recommended in several randomized trials but a thorough literature review has not yet been performed. Our aim was to determine the efficacy of split-dose vs other colon preparation regimens, the optimal products for use, and the most effective preparation volumes.
Methods
We performed systematic searches of MEDLINE, EMBASE, Scopus, CENTRAL, and ISI Web of Knowledge databases, from January 1980 to March 2014. A meta-analysis was done by including all randomized trials that assessed split-dose regimens vs day before colonoscopy preparation. We excluded studies that included pediatric or hospitalized patients, or patients with inflammatory bowel disease. The primary outcome was efficacy of bowel cleansing. Secondary outcomes included side effects, outcomes of procedures, patients’ willingness to repeat the procedure, and the amount of time required for patients to resume daily activities.
Results
We identified 47 trials that fulfilled our inclusion criteria (n=13,487 patients). Split-dose preparations provided significantly better colon cleansing than all day-before preparations (odds ratio [OR], 2.51; 95% confidence interval [CI], 1.86–3.39), as well as day-before preparations with PEG (OR, 2.60; 95% CI, 1.46–4.63), sodium phosphate (OR, 9.34; 95% CI, 2.12–41.11), or picosulfate (OR, 3.54; 95% CI, 1.95–6.45). PEG split-dose preparations of 3L or more yielded greater bowel cleanliness than lower-volume split-dose regimens (OR, 1.89; 95% CI, 1.01–3.46), but only in intention-to-treat analysis. A higher proportion of patients were willing to repeat split-dose vs day-prior cleansing (OR, 1.90; 95% CI, 1.05–3.46) and low-volume split-dose preparations vs high-volume split-dose preparation (OR, 4.95; 95% CI, 2.21–11.10). There were no differences between preparations in other secondary outcome measures.
Conclusion
Based on meta-analysis, split-dose regimens increase quality of colon cleansing and are preferred by patients, compared with day-before preparations. Additional research is required to further evaluate oral sulfate solution-based and PEG low-volume regimens.

On effectiveness in colorectal surgery : mechanical bowel preparation or not in elective colonic surgery and treatment options for elderly patients with rectal cancerJung, Bärbel January 2008 (has links)
The management of patients undergoing colorectal surgery has changed in recent decades. Efforts have been made to show that perioperative physiological stress to the patient can be minimised with standardised care programmes and thus improve short term outcome after colorectal surgery. Mechanical bowel preparation (MBP), for instance, has been questioned as part of standard management. There are studies highlighting the effect of cancer treatment and its side effects in the elderly, showing that geriatric patients benefit from oncological therapy in much the same way as younger patients. The impact of this information on surgical and oncological practice in Sweden today is not known. To assess the effectiveness of colorectal surgery we need both randomised controlled trials and population-based cohort studies. We have performed a trial on colonic surgery with and without preoperative mechanical bowel preparation, as well as a nation-wide register study comparing treatment and outcome of rectal cancer in two age groups. In a randomised controlled trial 1505 patients from 21 hospitals were randomised to MBP or no-MBP prior to open elective colonic resection. There were no differences in overall complication rates between the groups: cardiovascular 5.1% with MBP vs. 4.6% without MBP; general infection 7.9% vs. 6.8%; and surgical site complications 15.1% vs. 16.1%. The proportion of patients reaching at least one primary endpoint was 24.5% vs. 23.7% respectively. The patients experience of and postoperative recovery after MBP or no-MBP was evaluated in 105 of the patients in the bowel preparation trial at three of the participating hospitals. Sixty-five patients received MBP and 40 patients did not. In the MBP group 52% needed assistance with bowel preparation. Day 4 postoperatively patients in the no-MBP group perceived more discomfort than patients in the MBP group, p<0.05. Bowel emptying occurred significantly earlier in the no-MBP group than in the MBP group, p<0.05. In an experimental study the effect of MBP on intramucosal bacterial count was evaluated. Macroscopically normal colon mucosa was collected from 37 patients (20 MBP and 17 No-MBP) undergoing elective colorectal surgery at three hospitals. MBP did not influence the median colony count of E. coli, Bacteroides, or total median colony count, information that was previously unknown. These three studies imply that MBP can be omitted before elective colonic resection. In a population-based register study, treatment for rectal cancer in patients ≥ 75 years and those < 75 years was evaluated using data from the Swedish Rectal Cancer Register 1995-2004 (N=15104). This study revealed that preoperative radiotherapy was used less in patients > 75 years. There was also a higher threshold for surgery in this group, and they more often received a permanent stoma compared to younger patients. Outcome in terms of 5-year local recurrence rate and 5-year cancer-specific survival differed very little between the older and younger patient groups who underwent abdominal tumour resection with curative intent. We suggest future studies focusing on ways of reducing surgical and perioperative stress and on quality of life when assessing suitable treatment modalities for rectal cancer.

Qualidade da imagem nas pacientes com suspeita de Endometriose infiltrada profunda : comparação entre a ultrassonografia transvaginal antes e após a realização do preparo retal / Picture quality in patients with suspected deep endometriosis infiltrating : comparison transvaginal ultrasonography before and after performing the rectal preparationJuliana Vieira de Mendonça 25 July 2011 (has links)
Comparar a qualidade da imagem entre a ultrassonografia transvaginal sem preparo intestinal e após preparo intestinal nas pacientes com suspeita de endometriose infiltrativa profunda do compartimento posterior e avaliar do grau de desconforto das pacientes em relação ao preparo intestinal. Estudo transversal com dados coletados prospectivamente, incluindo 39 pacientes com suspeita clínica de endometriose do compartimento posterior do ambulatório de Endometriose do Hospital Universitário Pedro Ernesto (HUPE) da Universidade do Estado do Rio de Janeiro (UERJ), no Rio de Janeiro. As pacientes foram submetidas à ultrassonografia transvaginal (USTVG) sem preparo intestinal prévio, seguido de nova USTVG uma hora após realização do enema retal. Os vídeos dos exames gravados foram editados, com ênfase na avaliação do compartimento posterior, com interesse na identificação do nódulo retrocervical e do retossigmóide. Foram graduados conforme a qualidade da imagem pelo examinador e por um radiologista (ambos mascarados), que marcaram uma nota de 0 a 10, usando a escala analógica visual. Restaram apenas 26 pacientes. Em relação ao desconforto devido a realização do enema retal, todas pacientes (100%) relataram apenas um desconforto discreto. Conforme a opção escolhida pelos avaliadores em relação ao melhor método, eles concordaram em 13 (50%) pacientes que a ultrassonografia transvaginal com preparo retal é melhor. Foi usado o teste não-paramétrico de Wilcoxon para amostras dependentes. O p-valor obtido foi de 0.042, considerado significativo (abaixo de 0.05). Isto significa que a realização do enema retal antes da realização da ultrassonografia transvaginal proporcionou uma qualidade melhor na avaliação dos nódulos. A diferença entre as avaliações com e sem preparo retal é maior nos nódulos menores que 2cm, porque encontramos a diferença de 1,1 entre os valores das medianas dos dois tipos de exames. Nos nódulos maiores que 2cm, a diferença encontrada foi de apenas 0,65. A realização do enema retal previamente à realização da ultrassonografia transvaginal no diagnóstico do nódulo endometriótico mostra uma melhora discretamente significativa na qualidade da imagem, comparativamente a não realização de preparo intestinal prévio. Somente nos casos onde o nódulo era menor que 2 cm, foram encontrados valores estatisticamente significativos com o preparo retal. O enema retal causa discreto desconforto, porém isto não parece ser um fator limitante na realização da ultrassonografia com preparo intestinal. / To compare image quality between the transvaginal ultrasound without bowel preparation and after bowel preparation in patients with suspected deep infiltrating endometriosis of the posterior compartment and evaluate the degree of discomfort of patients in relation to bowel preparation. Cross sectional data collected prospectively, including 39 patients with clinical suspicion of endometriosis of the posterior compartment of the endometriosis clinic of the Hospital Universitário Pedro Ernesto (HUPE) State University of Rio de Janeiro (UERJ), in Rio de Janeiro . The patients underwent transvaginal sonography (USTVG) without prior bowel preparation, followed by new USTVG one hour after completion of the rectal enema. The recorded videos of the tests were published, with emphasis on evaluation of the posterior compartment, with interest in the identification of the nodule retrocervical and rectosigmoid. Were graded according to the quality of the image by the examiner and by a radiologist (both masked), which marked a score from 0 to 10, using the visual analog scale. That left only 26 patients. Regarding the realization of discomfort due to rectal enema, all patients (100%) reported only mild discomfort. Depending on the option chosen by the evaluators regarding the best method, they agreed in 13 (50%) patients with transvaginal ultrasound rectal preparation is better. We used the nonparametric Wilcoxon test for dependent samples. The p-value obtained was 0042 and considered significant (less than 0.05). This means that the completion of rectal enema prior to the transvaginal ultrasound provided a better quality in the evaluation of nodules. The difference between evaluations with and without rectal preparation is higher in nodules smaller than 2 cm, because we found a difference of 1.1 between the median values of the two types of tests. In nodules larger than 2cm, the difference was only 0.65.
The performance of the rectal enema prior to the performance of transvaginal sonography in the diagnosis of endometriotic nodule shows a slightly significant improvement in image quality, compared to non-completion of bowel preparation prior. Only in cases where the lump was less than 2 cm were found statistically significant values with rectal preparation. The rectal enema cause mild discomfort, but this does not seem to be a limiting factor in the performance of ultrasound with bowel preparation

Selective decontamination of the digestive tract in colorectal surgery reduces anastomotic leakage and costs: a propensity score analysisBogner, Andreas, Stracke, Maximilian, Bork, Ulrich, Wolk, Steffen, Pecqueux, Mathieu, Kaden, Sandra, Distler, Marius, Kahlert, Christoph, Weitz, Jürgen, Welsch, Thilo, Fritzmann, Johannes 22 February 2024 (has links)
Purpose Anastomotic leakage (AL) and surgical site infection (SSI) account for most postoperative complications in colorectal surgery. The aim of this retrospective trial was to investigate whether perioperative selective decontamination of the digestive tract (SDD) reduces these complications and to provide a cost-effectiveness model for elective colorectal surgery. Methods All patients operated between November 2016 and March 2020 were included in our analysis. Patients in the primary cohort (PC) received SDD and those in the historical control cohort (CC) did not receive SDD. In the case of rectal/sigmoid resection, SDD was also applied via a transanally placed Foley catheter (TAFC) for 48 h postoperatively. A propensity score-matched analysis was performed to identify risk factors for AL and SSI. Costs were calculated based on German diagnosis-related group (DRG) fees per case. Results A total of 308 patients (154 per cohort) with a median age of 62.6 years (IQR 52.5–70.8) were analyzed. AL was observed in ten patients (6.5%) in the PC and 23 patients (14.9%) in the CC (OR 0.380, 95% CI 0.174–0.833; P = 0.016). SSI occurred in 14 patients (9.1%) in the PC and 30 patients in the CC (19.5%), representing a significant reduction in our SSI rate (P = 0.009). The cost-effectiveness analysis showed that SDD is highly effective in saving costs with a number needed to treat of 12 for AL and 10 for SSI. Conclusion SDD significantly reduces the incidence of AL and SSI and saves costs for the general healthcare system.
