A survey of 500 clinically active, board-certified colon and rectal surgeons in the United States and Canada was conducted to obtain data regarding current methods of bowel preparation for elective colorectal surgery. A review of recent publications on preoperative bowel preparation was used to compare the current literature recommendations with the actual practice among the group surveyed. Responses were received from 352 of 500 colorectal surgeons to whom questionnaires were sent (70 percent response rate). All respondents used a mechanical preparation and some form of antibiotics. The favorite antibiotic regimen was oral antimicrobials combined with systemic antibiotics (88 percent). Concomitant administration of oral neomycin-erythromycin base and a systemic second generation cephalosporin active against both anaerobic and aerobic colonic bacteria, together with oral polyethelene glycol electrolyte mechanical colonic cleansing, was the most popular method of preoperative bowel preparation (58 percent). The second most frequent method of mechanical bowel cleansing consisted of conventional enemas, dietary restrictions, and cathartic preparations (36 percent). Mannitol solution (5 percent), and whole-gut irrigation per nasogastric tube (1 percent) were the least popular methods of mechanical bowel cleansing. The literature supports the current methods of preoperative bowel preparation used by the vast majority of surgeons surveyed.Poster presentation at the meeting of the American Society of Colon and Rectal Surgeons, Toronto, Canada, June 11 to 16, 1989. 相似文献

It has been suggested that wound infection rates after colorectal operations are influenced more by the presence of adequate
tissue levels of antimicrobials at the time of contamination than by the extent of bacterial colonization of the intestinal
lumen. There are, however, theoretical grounds for the belief that both levels are important. The authors therefore conducted
a random control trial in 119 consecutive patients undergoing elective colorectal operations, comparing the results in a group
receiving purely parenteral antimicrobial prophylaxis with those in one having a combined oral and parenteral regimen. The
results in 83 contemporary nonrandomized patients, all of whom had the combined prophylactic regimen, are also reported. Oral
bowel preparation resulted in a significantly smaller number of operation cultures showing growth of fecal gram-negative aerobes
and anaerobes than did the purely parenteral regimen. There were more isolations of enterococci in the combined group but
the excess did not achieve statistical significance. The rates of infective complications were higher in the parenteral than
in the combined group, the difference in wound infection rates being statistically significant; the figures were 27.6 percent
and 13.9 percent, respectively (P=.04). It is concluded that, in colorectal operations, it is advisable not only to ensure adequate tissue levels of antimicrobials
but also to reduce the risk of endogenous bacterial infection by partially decontaminating the bowel. 相似文献

Physiologic effects of bowel preparation 总被引:4,自引:2,他引:4
PURPOSE: Despite the universal use of bowel preparation before colonoscopy and colorectal surgery, the physiologic effects have not been described in a standardized setting. This study was designed to investigate the physiologic effects of bowel preparation.METHODS: In a prospective study, 12 healthy volunteers (median age, 63 years) underwent bowel preparation with bisacodyl and sodium phosphate. Fluid and food intake were standardized according to weight, providing adequate calorie and oral fluid intake. Before and after bowel preparation, weight, exercise capacity, orthostatic tolerance, plasma and extracellular volume, balance function, and biochemical parameters were measured.RESULTS: Bowel preparation led to a significant decrease in exercise capacity (median, 9 percent) and weight (median, 1.2 kg). Plasma osmolality was significantly increased from 287 to 290 mmol kg–1, as well as increased phosphate and urea concentrations, whereas calcium and potassium concentrations decreased significantly after bowel preparation. No differences in plasma or extracellular volumes were seen. Orthostatic tolerance and balance function did not change after bowel preparation.CONCLUSIONS: Bowel preparation has significant adverse physiologic effects, which may be attributed to dehydration. The majority of these findings is small and may not be of clinical relevance in otherwise healthy patients undergoing bowel preparation and following recommendations for oral fluid intake.Supported by grants from the University of Copenhagen and the Danish Research Council (no. 22-01-0160).Presented at the meeting of the American Society of Anesthesiologists, San Francisco, California, October 11 to 15, 2003. 相似文献

AIM: To compare the quality and tolerance of esophagogastroduodenoscopy (EGD)-assisted and conventional split-dose polyethylene glycol electrolyte solution for inpatient colonoscopy.METHODS: The study was a randomized controlled trial in hospitalized patients. Hospitalized patients undergoing colonoscopy the day following EGD for evaluation of gastrointestinal (GI) bleeding or other symptoms. Patients randomized to either EGD-assisted bowel prep [2 L polyethylene glycol (PEG) administered endoscopically into distal duodenum at time of EGD, plus 1 L PEG orally the following day] or conventional-PEG (2 L PEG orally the evening prior and 1 L PEG orally the following day). The main outcome measurements are bowel preparation quality and patient tolerance of bowel prep.RESULTS: Forty-two patients randomized to EGD-assisted bowel prep and 40 patients to conventional-PEG. Overall mean ± SD preparation quality was superior for EGD-PEG (4.1 ± 2.8) vs conventional-PEG (6.5 ± 3.1; P = 0.0005). Seventy-four percent of patients rated EGD-PEG as easy or slightly difficult to tolerate compared to 46% for standard-PEG (P = 0.0133). Mean EGD-procedural time was greater for EGD-assisted subject (24 ± 10 min) compared to conventional-PEG prep subjects (15 ± 7 min; P < 0.0001). Conscious sedation requirements did not differ between groups. There were no significant prep-related adverse events in either group.CONCLUSION: In selected hospitalized patients, compared to a conventional split-dose regimen, use of EGD to administer the majority of PEG solution improves patient tolerance and quality of bowel preparation for colonoscopy. 相似文献

Summary 1. Two hundred and twenty-two patients were examined by sigmoidoscopy following the use of one of four cleansing preparations: 50% magnesium sulphate solution, Fleet's solution, normal saline, and Dulcolax tablets and suppositories.2. Fifty per cent magnesium sulphate produced the highest percentage of excellently cleansed patients—69.7% in 96 patients.3. Almost equally useful, for the purpose described in this report, is Fleet's solution—58.7 per cent excellent cleansing, 84.7 per cent satisfactory cleansing (E and G), and less than 10 per cent marked congestion in 46 patients.4. Dulcolax, though practical, easily administered, and only mildly irritating, as employed in our study, gave only moderately satisfactory results—with 66 per cent satisfactory cleansing preparations in 53 patients.5. Normal saline was the least effective cleansing agent and was abandoned because of the poor results obtained—48.1 per cent satisfactory in 27 patients.6. There was little significant difference in side effects and rectal irritation in the preparations used, with the exception of normal saline, which produced much less congestion and mucus secretion.7. Cleansing the rectosigmoid, prior to sigmoidoscopy, by the method described in this report, using 50% magnesium sulphate, is a simple, efficient, safe, and inexpensive method of preparation, well tolerated by the patient. 相似文献

Background Mechanical bowel preparation prior to colorectal surgery may reduce infectious complications, facilitate tumor localization, and allow intraoperative colonoscopy, if required. However, recent data suggest that mechanical bowel preparation may not facilitate a reduction in infectious complications. During laparoscopic colectomy, manual palpation is blunt, thereby potentially compromising tumor localization. The aim of this study was to assess the utility of mechanical bowel preparation in laparoscopic colectomy.Materials and methods A retrospective medical record review of all patients who underwent laparoscopic colectomy was performed. Patients were divided into two groups: those who had preoperative mechanical bowel preparation (Group A) or those who did not (Group B). All relevant perioperative data were reviewed and compared.Results Two hundred patients underwent laparoscopic colectomy; 68 (34%) were in Group A and 132 (66%) were in Group B. Sixteen (8%) patients required intraoperative colonoscopy for localization and were evenly distributed between the two groups. The incidence of conversion to laparotomy was slightly higher in Group B (14 vs 9%) due to difficult localization in some cases; however, this difference did not reach statistical significance. Furthermore, there was no significant difference in the postoperative complication rate between the two groups. Specifically, an anastomotic leak and a wound infection were recorded in 4 and 12% of patients in Group A compared to 3 and 17% in Group B, respectively.Conclusions Laparoscopic colectomy may be safely performed without preoperative mechanical bowel preparation, although difficult localization may lead to a slightly higher conversion rate. Appropriate patient selection for laparoscopic colectomy without mechanical bowel preparation is essential. Furthermore, bowel preparation should be considered in cases of small and nonpalpable lesions.Dual first authorship—Zmora and Lebedyev, the first two authors, equally contributed to this study.Presented as a poster at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Denver, CO, March 31–April 3, 2004. 相似文献

Improved capsule endoscopy after bowel preparation 总被引:18,自引:0,他引:18
BACKGROUND: The diagnostic yield of capsule endoscopy depends on the quality of visualization of the small-bowel wall and complete passage through the small bowel. This study examined the effect of bowel preparation on the volume of intestinal content and on small-bowel transit. METHODS: Sixty-one consecutive patients (34 men, 27 women; mean age 56 years, range 17-88 years) were enrolled in the study. Although not randomized, 33 patients received a bowel preparation, and 28 had no preparation. Gastric emptying, small-bowel transit time, overall preparation assessment, and bowel-wall visualization were evaluated by 3 investigators who were unaware of whether the patient had undergone bowel preparation. RESULTS: Small-bowel transit time was significantly shorter in patients with bowel preparation (median 213 minutes: 95% CI[190, 267]) than in those without preparation (median 253 minutes: 95% CI[228, 307]) (p <0.01). The capsule reached the cecum in 97% of patients in the bowel-preparation group, compared with 76% in the nonpreparation group (p=0.02). Bowel preparation improved the quality of visualization significantly; this effect was more pronounced in the distal small bowel. CONCLUSIONS: This study demonstrated that bowel preparation accelerates small-bowel capsule transit and leads to a higher rate of complete capsule endoscopy. Visualization of the small bowel was improved by bowel preparation. Bowel preparation before capsule endoscopy is recommended. 相似文献

Predictors of inadequate bowel preparation for colonoscopy 总被引:10,自引:0,他引:10

OBJECTIVE: Inadequate preparation of the bowel for colonoscopy can result in both missed pathological lesions and cancelled procedures. We looked prospectively at the quality of colonic preparation and evaluated potential associations between specific patient characteristics and inadequate colonic preparation. METHODS: Data were gathered on consecutive patients presenting for colonoscopy who received either a polyethylene glycol lavage or oral sodium phosphate bowel preparation. Patient demographic and medical history information was gathered before scheduled colonoscopy. The endoscopist evaluated the preparation quality during the procedure. Complete data were gathered on 649 of 714 eligible patients (90.8%). Possible predictors of inadequate colonic preparation were analyzed using univariate statistics and multivariate logistic regression models. RESULTS: An inadequate colonic preparation was reported in 21.7% of observed colonoscopies. Only 18% of patients with an inadequate colonic preparation reported a failure to adequately follow preparation instructions. A later colonoscopy starting time, a reported failure to follow preparation instructions, inpatient status, a procedural indication of constipation, taking tricyclic antidepressants, male gender, and a history of cirrhosis, stroke or dementia were all independent predictors of an inadequate colon preparation (all p < 0.05). A procedural indication of previous polypectomy was a negative predictor of inadequate colonic preparation (p < 0.05). CONCLUSION: Several patient characteristics were significantly associated with colonic preparation quality independent of preparation type, compliance with preparation instructions, and procedure starting time. This information may help to identify patients at an increased risk for inadequate colonic preparation for whom alternative preparation protocols would be appropriate. 相似文献
