RESUMO

BACKGROUND: Surgery has been used as part of breast cancer treatment for centuries; however any surgical procedure has the potential risk of infection. Infection rates for surgical treatment of breast cancer are documented at between 3% and 15%, higher than average for a clean surgical procedure. Pre- and perioperative antibiotics have been found to be useful in lowering infection rates in other surgical groups, yet there is no consensus on the use of prophylactic antibiotics for breast cancer surgery. This is an update of a Cochrane Review first published in 2005 and last updated in 2014. OBJECTIVES: To determine the effects of prophylactic (pre- or perioperative) antibiotics on the incidence of surgical site infection (SSI) after breast cancer surgery. SEARCH METHODS: For this fourth update, in August 2018 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase; and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA: We included randomised controlled trials of pre- and perioperative antibiotics for patients undergoing surgery for breast cancer. Primary outcomes were rates of surgical site infection (SSI) and adverse reactions. DATA COLLECTION AND ANALYSIS: Three review authors independently examined the title and abstracts of all studies identified by the search strategy, then assessed study quality and extracted data from those that met the inclusion criteria. We contacted study authors to obtain missing information. We evaluated the certainty of evidence using the GRADE approach. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: A total of 11 randomised controlled trials (2867 participants) were included in the review. No new studies were identified in this update. All studies included breast cancer patients and were based in the hospital setting. Ten studies evaluated preoperative antibiotic compared with no antibiotic or placebo. One study evaluated perioperative antibiotic compared with placebo or no antibiotic. Pooling of the results demonstrated that prophylactic antibiotics administered preoperatively probably reduce the incidence of SSI for patients undergoing breast cancer surgery without reconstruction (pooled risk ratio (RR) 0.67, 95% confidence interval (CI) 0.53 to 0.85; moderate certainty evidence). Anticipated absolute effects were calculated for the outcome incidence of SSI; 105 per 1000 for the none or placebo group and 71 per 1000 (95% CI 56 to 89) for the preoperative antibiotic prophylaxis group. Analysis of the single study comparing perioperative antibiotic with no antibiotic was inconclusive for incidence of SSI (RR 0.11, 95% CI 0.01 to 1.95; very low certainty evidence). No studies presented separate data for patients who underwent reconstructive surgery at the time of removal of the breast tumour.Secondary outcomes were not consistently included in the studies investigating preoperative antibiotic prophylaxis. It is very uncertain whether there is a difference in incidence of adverse events between the treatment and no treatment or placebo groups (10 studies, 2818 participants); very low certainty evidence downgraded one level for serious risk of bias, one level for serious inconsistency and one level for serious imprecision. It is unclear whether there is a difference in time to onset of infection between the treatment and no treatment or placebo groups (4 studies, 1450 participants); low certainty evidence downgraded one level for serious risk of bias and one level for serious inconsistency. It is unclear whether there is a difference in rates of readmission to hospital between the treatment and placebo groups (3 studies, 784 participants); low certainty evidence downgraded one level for serious inconsistency and one level for serious risk of bias. It is unclear whether there is a difference in cost of care between the treatment and no treatment or placebo groups (2 studies, 510 participants); low certainty evidence downgraded one level for serious risk of bias and one level for serious inconsistency. No analysable secondary outcome data were reported for the single study evaluating perioperative antibiotics. AUTHORS' CONCLUSIONS: Prophylactic antibiotics administered preoperatively probably reduce the risk of SSI in patients undergoing surgery for breast cancer. However, it is very uncertain whether there is an effect on incidence of adverse events. Furthermore, the effects on time to onset of infection, readmission to hospital and cost of care remain unclear. Further studies are required to establish the best protocols for clinical practice.

RESUMO

Mechanical bowel preparation used to be a standard procedure for a long time. Nowadays routine use of MBP seems to be debatable thus alternative approaches, e.g. avoiding any bowel preparation completely or using of MBP with oral antibiotics are considered. Data on performing different kinds of bowel preparation is reviewed in this article.

RESUMO

OBJECTIVE: to evaluate the feasibility of abbreviated fasting in oncologic colorectal surgeries, as well as the impact on the surgical outcome of the patients. METHODS: prospective randomized comparative study with patients undergoing elective colorectal cancer surgeries from May to September 2017. Patients were randomized electronically into two groups according to the preoperative fast to be adopted: conventional or abbreviated. RESULTS: of the 33 patients included, 15 followed the abbreviated fasting protocol and 18 the conventional fasting. Both groups had comparable profiles. No patient underwent mechanical preparation of the colon. In 69.7% of the cases, surgery involved low rectal dissection. The procedures were equivalent in relation to intraoperative variables and severe complications. The time to achieve complete oral intake was shorter for abbreviated fasting (10 versus 16 days, p=0.001), as well as the length of inhospital stay (2 versus 4 days, p=0.009). Hospital costs were lower in the abbreviated fasting (331 versus 682 reais, p<0.001). The univariable analysis revealed a correlation between complete oral intake and abbreviated fasting [HR 0.29 (IC95%: 0.12-0.68] and abdominal distension [HR 0.12 (IC95% 0.01-0.94)]. After multivariable analysis, abbreviated fasting presented a lower time for complete oral intake [HR 0.39 (IC95%: 0.16-0.92]. CONCLUSION: the abbreviated preoperative fasting favors the metabolic-nutritional recovery, reducing the time for complete oral intake. The implementation of the abbreviation protocol reduces hospital admission costs.

RESUMO

BACKGROUND: The aim of this study was, from the Chinese healthcare perspective, to assess the cost-effectiveness of positron-emission tomography-computed tomography (PET-CT) with F-fluorodeoxyglucose (F-FDG) in preoperation staging for nonsmall-cell lung cancer (NSCLC) with resected monometastatic disease based on a retrospective study. This study was conducted from January 2017 to February 2019 at an academic hospital. METHODS: A Markov model and 3 decision-tree models were designed to calculate the long-term medical costs, outcomes, and incremental cost-effectiveness ratios (ICERs) of the 2 diagnostic strategies (PET-CT and conventional CT). Model robustness was assessed in sensitivity analyses. RESULTS: For the base-case analysis, preoperative PET-CT evaluation for NSCLC with resected monometastatic disease provided an additional 1.475, 2.129, and 2.412 life-years (LYs), in the time horizon of 10-, 20-, and 30-year, respectively, and the ICERs for the PET-CT group compared with the conventional CT group were $1153, $1393, and $1430 per LY, separately. The acceptability curves demonstrated that when the willingness-to-pay (WTP) thresholds ranged from $500 to $3000/LY, the probability of cost-effectiveness changed varied dramatically, and at WTP > $3000, the probability that the PET-CT group achieved cost-effectiveness was 100%. Sensitivity analyses suggested that the models we designed were robust. CONCLUSION: Compared with conventional CT scan, preoperative F-FDG PET-CT evaluation for patients with resected monometastatic NSCLC is cost-effective from the Chinese healthcare perspective. Preoperative F-FDG PET-CT evaluation should be popularized for patients with resected monometastatic NSCLC.

RESUMO

Insulinomas are rare endocrine malignancies of the pancreas that require surgical resection but can be difficult to localize preoperatively. We sought to review and improve the accuracy of preoperative localization techniques at our institution. We retrospectively reviewed all insulinomas that underwent resection at our institution between 1998 and 2016. Localization techniques include selective arterial calcium stimulation (CaStim), CT, MRI, angiography, and somatostatin receptor scintigraphy. Thirty-eight patients had pathologically proven insulinomas on surgical resection. Localization accuracies of CaStim, CT, and MRI were 89 per cent (31/35), 67 per cent (22/33), and 46 per cent (11/24), respectively. When compared with CT alone and CaStim alone, the combination of these two modalities resulted in 100 per cent preoperative localization (30/30), whereas the use of CaStim alone resulted in 80 per cent (4/5) localization and the use of CT alone resulted in 66 per cent (2/3) localization. Four of our patients had both negative CT and MRI. Among these patients, CaStim was 100 per cent localizing and the only positive modality for these patients. These data confirm that CaStim is accurate in preoperatively identifying single and multiple insulinomas; and when combined with CT, this accuracy is increased to 100 per cent. Based on these data, we propose that a dual imaging approach is a superior means of preoperative localization.

RESUMO

AIMS: The aim of this study was to determine the risk of local recurrence and survival in patients with osteosarcoma based on the proximity of the tumour to the major vessels. PATIENTS AND METHODS: A total of 226 patients with high-grade non-metastatic osteosarcoma in the limbs were investigated. Median age at diagnosis was 15 years (4 to 67) with the ratio of male to female patients being 1.5:1. The most common site of the tumour was the femur (n = 103) followed by tibia (n = 66). The vascular proximity was categorized based on the preoperative MRI after neoadjuvant chemotherapy into four types: type 1 > 5 mm; type 2 ≤ 5 mm, > 0 mm; type 3 attached; type 4 surrounded. RESULTS: Limb salvage rate based on the proximity type was 92%, 88%, 51%, and 0% for types 1 to 4, respectively, and the overall survival at five years was 82%, 77%, 57%, and 67%, respectively (p < 0.001). Local recurrence rate in patients with limb-salvage surgery was 7%, 8%, and 22% for the types 1 to 3, respectively (p = 0.041), and local recurrence at the perivascular area was observed in 1% and 4% for type 2 and 3, respectively. The mean microscopic margin to the major vessels was 6.9 mm, 3.0 mm, and 1.4 mm for types 1 to 3, respectively. In type 3, local recurrence-free survival with limb salvage was significantly poorer compared with amputation (p = 0.025), while the latter offered no overall survival benefit. In this group of patients, factors such as good response to chemotherapy or limited vascular attachment to less than half circumference or longitudinal 10 mm reduced the risk of local recurrence. CONCLUSION: The proximity of osteosarcoma to major blood vessels is a poor prognostic factor for local control and survival. Amputation offers better local control for tumours attached to the blood vessels but does not improve survival. Limb salvage surgery offers similar local control if the tumour attachment to blood vessels is limited. Cite this article: Bone Joint J 2019;101-B:1024-1031.

RESUMO

AIMS: Prosthetic joint infection (PJI) and aseptic loosening in total hip arthroplasty (THA) can present with pain and osteolysis. The Musculoskeletal Infection Society (MSIS) has provided criteria for the diagnosis of PJI. The aim of our study was to analyze the utility of F18-fluorodeoxyglucose (FDG) positron emission tomography (PET) CT scan in the preoperative diagnosis of septic loosening in THA, based on the current MSIS definition of prosthetic joint infection. PATIENTS AND METHODS: A total of 130 painful unilateral cemented THAs with a mean follow-up of 5.17 years (sd 1.12) were included in this prospective study. The mean patient age was 67.5 years (sd 4.85). Preoperative evaluation with inflammatory markers, aspiration, and an F18 FDG PET scan were performed. Diagnostic utility tests were also performed, based on the MSIS criteria for PJI and three samples positive on culture alone. RESULTS: The mean erythrocyte sedimentation rate, C-reactive protein, and white cell count were 47.83 mm/hr, 25.21 mg/l, and 11.05 × 109/l, respectively. The sensitivity, specificity, accuracy, negative predictive value, and false-positive rate of FDG PET compared with MSIS criteria were 94.87%, 38.46 %, 56.38%, 94.59 %, and 60.21%, respectively. The false-positive rate of FDG PET compared with culture alone was 77.4%. CONCLUSION: FDG PET has a definitive role in the preoperative evaluation of suspected PJI. This the first study to evaluate its utility based on MSIS criteria and compare it with microbiology results alone. However, FDG PET has a high false-positive rate. Therefore, we suggest that F18 FDG PET is useful in confirming the absence of infection, but if positive, may not be confirmatory of PJI. Cite this article: Bone Joint J 2019;101-B:910-914.

RESUMO

BACKGROUND: Accurate alignment of toric intraocular lens (TIOL) to steep corneal astigmatic axis is important to achieve effective postoperative results. The authors compare the accuracy of astigmatism correction using automated and manual marking in TIOL implantation during cataract surgery. METHODS: One hundred thirty-two eyes with nuclear density from Grade 2 to 4 were randomly subdivided into 2 groups (automated and manual marking). All patients underwent manual marking and the steep axis was compared to SensoMotoric Instruments (SMI). After phacoemulsification, 62 patients underwent toric IOL implantation using the SMI and 70 patients underwent toric IOL implantation using manual marking. Intraoperative measurement was the steep axis difference. Clinical measurements included preoperative and postoperative best corrected visual acuity (BCVA), and TIOL axis. RESULTS: The intraoperative steep axis difference between SMI and manual marking was 7.86 ± 6.4 degrees. The difference between the preoperative steep axis and the postoperative TIOL axis using SMI (3.63 ± 1.12 degrees) was significantly lower than that using manual marking (8.29 ± 2.23 degrees) (P < 0.05). CONCLUSIONS: The steep axis measurements may be different when using SMI vs. manual marking. The SMI is more accurate than manual marking for TIOL implantation during cataract surgery. TRIAL REGISTRATION: Current Controlled Trials ISRCTN12294725 , Retrospectively registered, on 20 July 2018.

RESUMO

BACKGROUND: Abdominal disorders can alter respiratory function and increase the morbidity and mortality of patients with chronic obstructive pulmonary disease. AIM: To improve the physiotherapeutic and muscular capacity in chronic obstructive pulmonary muscular inspiration in the preoperative preparation in abdominal surgeries. METHOD: Retrospective and documentary study using SINPE © , clinical database software of patients with chronic obstructive pulmonary disease and candidates to abdominal operation. The sample consisted of 100 men aged 55-70 years, all with chronic obstructive pulmonary disease who underwent preoperative physiotherapeutic treatment. They were divided into two groups of 50 individuals (group A and group B). In group A the patients were treated with modern mobility techniques for bronchial clearance and the strengthening of the respiratory muscles was performed with IMT ® Threshold. In group B the treatment performed for bronchial obstruction was with classic maneuvers and for the strengthening of the respiratory muscles for flow incentive was used Respiron ® . RESULTS: Both groups obtained improvement in the values ​​of the PiMáx after the different treatments. Group A obtained greater change in the intervals and a more significant increase of the values of the PiMax in relation to the average pre and post-treatment. However, when analyzing the variance and the standard deviation of the samples, group B presented the best results showing more homogeneity. CONCLUSIONS: The modern and traditional bronchial clearance techniques associated with inspiratory muscle training were equally effective in gaining inspiratory muscle strength with increased Pmax. In this way, the two can be used in the preoperative preparation of patients with chronic obstructive pulmonary disease and referred to abdominal operations.

RESUMO

Management of resectable esophageal carcinoma is based on a multimodal treatment associating neo-adjuvant chemoradiation before surgery. This therapeutic sequence allows a disease-free survival rate at 2 years around 45% but remains associated with a high post-operative morbidity. In case of definitive chemoradiotherapy, the dose delivered to the macroscopic disease is a controversial topic since decades and the prognosis of patients treated in this setting at the dose of 50Gy remains poor. This article proposes a review of the main published data and the ongoing studies related to the management of these patients.

RESUMO

AIMS: While previously underappreciated, factors related to the spine contribute substantially to the risk of dislocation following total hip arthroplasty (THA). These factors must be taken into consideration during preoperative planning for revision THA due to recurrent instability. We developed a protocol to assess the functional position of the spine, the significance of these findings, and how to address different pathologies at the time of revision THA. PATIENTS AND METHODS: Prospectively collected data on 111 patients undergoing revision THA for recurrent instability from January 2014 to January 2017 at two institutions were included (protocol group) and matched 1:1 to 111 revisions specifically performed for instability not using this protocol (control group). Mean follow-up was 2.8 years. Protocol patients underwent standardized preoperative imaging including supine and standing anteroposterior (AP) pelvis and lateral radiographs. Each case was scored according to the Hip-Spine Classification in Revision THA. RESULTS: Survival free of dislocation at two years was 97% in the protocol group (three dislocations, all within three months of surgery) versus 84% in the control group (18 patients). Furthermore, 77% of the inappropriately positioned acetabular components would have been unrecognized by supine AP pelvis imaging alone. CONCLUSION: Using the Hip-Spine Classification System in revision THA, we demonstrated a significant decrease in the risk of recurrent instability compared with a control group. Without the use of this algorithm, 77% of inappropriately positioned acetabular components would have been unrecognized and incorrect treatment may have been instituted.

RESUMO

OBJECTIVE: To investigate the effects of preoperative anxiety relieving on electrophysiological changes in patients undergoing off-pump coronary artery bypass surgery. METHODS: A total of 61 patients at ASA III risk group in the age range of 18-65 years were enrolled in the present study. Patients were randomly divided into two groups. Group S (Sedation group) was administered 0.04 mg/kg lorazepam per os (PO) twice before the operation. Group C (control group) was not administered with any anxiolytic premedication. State Trait Anxiety Inventory (STAI-I) and Beck Anxiety Inventory (BAI) were used to evaluate the level of anxiety. Electrocardiography (ECG), pulse oximeter and standard monitoring were performed for each patient. QT and P dispersions in each derivation of all ECGs were calculated. RESULTS: Preoperative STAI-I scores were significantly lower in sedation group compared to the controls. Mean values of QT dispersion measured before induction, at the 1st minute of induction, 30th second of intubation and 4th minute of intubation in sedation group were significantly reduced compared to controls (P=0.024; P=0.027; P=0.001; P=0.033, respectively). The mean values of P dispersion measured before induction, at the 3rd minute of induction, 30th second of intubation and 4th minute of intubation in sedation group were significantly reduced compared to controls (P=0.001; P=0.020; P=0.023; P=0.005, respectively). CONCLUSION: Elevated anxiety levels in patients undergoing coronary bypass surgery have a negative effect through prolonged QT and P-wave dispersion times. Anxiolytic treatment before surgery may be useful to prevent ventricular and atrial arrhythmias and associated complications through decreasing the QT and P-wave dispersion duration.

RESUMO

OBJECTIVES: The purpose of the current study was to investiagte the diagnostic accuracy of F18 flucholine (FCH) positron emission tomography/CT (PET/CT) for pre-operative lymph node (LN) staging in newly diagnosed prostate cancer (PCa) patients using meta-analysis. METHODS: PubMed and Embase from the earliest available date of indexing through December 31, 2018, were searched for studies evaluating the diagnostic performance of F18 FCH PET/CT for preoperative LN staging in newly diagnosed PCa. We determined the sensitivities and specificities across studies, calculated positive and negative likelihood ratios (LR + and LR-), and constructed summary receiver operating characteristic curves. RESULTS: Across seven studies (627 patients), the pooled sensitivity was 0.57 [95% confidence interval (CI) (0.42-0.70)] and a pooled specificity of 0.94 [95% CI (0.89-0.97)]. Likelihood ratio (LR) syntheses gave an overall positive likelihood ratio (LR+) of 10.2 (95% CI; 5.0-21.0) and negative likelihood ratio (LR-) of 0.46 (95% CI; 0.33-0.64). The pooled diagnostic odds ratio was 22 (95% CI; 9-54). CONCLUSIONS: F18 FCH PET/CT shows a low sensitivity and high specificity for the detection of metastatic LNs in patients with newly diagnosed PCa. Also, F18 FCH PET/CT is only useful for confirmation of LN metastasis (when positive) in PCa patients. ADVANCES IN KNOWLEDGE: F18 FCH PET/CT demonstrates low sensitivity but high specificity for diagnosis of metastatic LNs in patients with newly diagnosed PCa. Also, F18 FCH PET/CT is only useful for confirmation of LN metastasis (when positive) in PCa patients.

RESUMO

OBJECTIVE: To develop and validate clinical-radiomics nomograms based on three-dimensional CT and multiparametric MRI (mpMRI) for pre-operative differentiation of sacral chordoma (SC) and sacral giant cell tumor (SGCT). METHODS: A total of 83 SC and 54 SGCT patients diagnosed through surgical pathology were retrospectively analyzed. We built six models based on CT, CT enhancement (CTE), T1 weighted, T2 weighted, diffusion-weighted imaging (DWI), and contrast-enhanced T1 weighted features, two radiomics nomograms and two clinical-radiomics nomograms combined radiomics mixed features with clinical data. The area under the receiver operating characteristic curve (AUC) and accuracy (ACC) analysis were used to assess the performance of the models. RESULTS: SC and SGCT presented significant differences in terms of age, sex, and tumor location (tage = 9.00, χ2sex = 10.86, χ2location = 26.20; p < 0.01). For individual scan, the radiomics model based on diffusion-weighted imaging features yielded the highest AUC of 0.889 and ACC of 0.885, followed by CT (AUC = 0.857; ACC = 0.846) and CT enhancement (AUC = 0.833; ACC = 0.769). For the combined features, the radiomics model based on mixed CT features exhibited a better AUC of 0.942 and ACC of 0.880, whereas mixed MRI features achieved a lower performance than the individual scan. The clinical-radiomics nomogram based on combined CT features achieved the highest AUC of 0.948 and ACC of 0.920. CONCLUSIONS: The radiomics model based on CT and multiparametricMRI present a certain predictive value in distinguishing SC and SGCT, which can be used for auxiliary diagnosis before operation. The clinical-radiomics nomograms performed better than radiomics nomograms. ADVANCES IN KNOWLEDGE: Clinical-radiomics nomograms based on CT and mpMRI features can be used for preoperative differentiation of SC and SGCT.

RESUMO

Purpose: Preoperative anxiety over cataract surgery affects a large number of patients. This study aims to evaluate the effect of slow-stroke back massage on the anxiety of candidates for cataract surgery. Design: Quasi-experimental study. Methods: This study was a quasi-experimental study, which involved 60 candidates for cataract surgery referred to Amiralmomenin Hospital, Zabol in Iran between August 1, 2015, and March 30, 2016. These patients were randomly divided into two groups of slow-stroke back massage group (n=30) and control group (n=30). After obtaining an informed consent, the anxiety levels were measured by the Spielberger state trait anxiety questionnaire in the slow-stroke back massage group and the control group on the morning of the surgery before and immediately after the massage. SPSS software version 22 was used for data analysis. Independent t-test and chi-square test were used to compare the data. Findings: According to the results, there was a significant difference between the anxiety levels of the patients in the intervention group before and after the massage (p < 0.001). Conclusions: Based on the results of this study, Slow-stroke-back massage, which is a low-cost and safe method, significantly reduces anxiety in patients who are candidates for cataract surgery.

RESUMO

Congenital uterovaginal aplasia commonly occurs in Mayer-Rokitansky-Küster-Hauser syndrome. Various methods of neovagina creation exist, including nonsurgical self-dilation, surgical dilation, and surgical procedures involving skin or intestinal transplants. Subsequent uterus transplantation is necessary to enable pregnancy. We review the main characteristics, advantages, and disadvantages of established neovagina creation methods and discuss their suitability regarding subsequent uterus transplantation. Suitability criteria include sufficient vaginal length, absence of previous major intra-abdominal surgery, a natural vaginal axis, and a natural vaginal epithelium. In conclusion, Vecchietti-based laparoscopically assisted neovagina creation provides ideal functional conditions for uterus transplantation. Nonsurgical self-dilation and Wharton-Sheares-George vaginoplasty may also be suitable. TWEETABLE ABSTRACT: This review discusses the main advantages and disadvantages of neovagina creation methods with regard to subsequent uterus transplantation.

RESUMO

To test the hypothesis claimed in recent studies that quality of bowel preparation for colonoscopy could be influenced by the time of the day colonoscopy is performed. Do patients in morning list have better bowel preparation than those on the afternoon list? Retrospective analysis of 736 consecutive patients who had colonoscopy from 1st August to 31st December 2012. Patients with poor bowel preparation (Boston Bowel Prep Score 6 or less) were identified (n = 242). Colonoscopy reports of these patients analysed. Patients were stratified into two groups (am and pm) and results compared. Mean patient age 63.9 years (range 19-89). Male to female ratio 1:1. 92% of patients were given Moviprep. for bowel preparation. 32.9% (242/736) of patients were identified as having inadequate bowel preparation. 37.7% of morning list patients had poor bowel preparation. 26.7% of afternoon list patients had poor bowel preparation. 14.7% (108/736) had incomplete colonoscopy, of which 26.9% (29/108) were due to poor bowel preparation. The commonest reasons for incomplete examination were patient discomfort & bowel looping. Our study demonstrates that morning session patients had poorer bowel preparation than the afternoon session patients in contrast to published evidence in recent literature. This implies that timing of bowel preparation is probably more important than timing of colonoscopy. Poor bowel preparation does not seem to have a significant impact on the colonoscopy failure rate in this series.
