Abstract
PURPOSE The use of mechanical bowel preparation (MBP) before pediatric colorectal surgery remains the standard of care for many pediatric surgeons, though the value of MBP remains unclear. The aim of this study was to systematically review and analyze the effect of MBP on the incidence of postoperative complications; anastomotic leakage, intra-abdominal infection, and wound infection, following colorectal surgery in pediatric patients. METHODS Embase, MEDLINE, Web of Science, and CINAHL databases were searched to compare the effect of MBP versus no MBP prior to elective pediatric colorectal surgery on postoperative complications. After critical appraisal of included studies, meta-analyses were conducted using a random-effect model. RESULTS 1731 papers were retrieved; 2 randomized controlled trials and 4 retrospective cohort studies met the inclusion criteria. The overall quality of evidence was low. MBP before colorectal surgery did not significantly decrease the occurrence of anastomotic leakage, intra-abdominal infection, or wound infection compared to no MBP. CONCLUSIONS On the basis of the existing evidence, the use of MBP before colorectal surgery in children seems not to decrease the incidence of postoperative complications compared to no MBP. To overcome confounding factors such as antibiotic prophylaxis, age and type of operation, a multicentre prospective study is suggested to validate these results.

Abstract
Colonoscopy is a routinely performed procedure in children and adolescents. Proper visualization of the intestinal mucosa, completion of the procedure, including examination of the terminal ileum, detection of pathological lesions, and therapeutic maneuvers, all are highly dependent on the quality of the bowel preparation. A significant proportion of patients, in some reports up to one third, are inadequately prepared for the examination, which leads to extended procedure time, incomplete examination, or need for repeat procedure. Aside from efficacy and safety, the most important aspects of colon preparation in pediatrics are ease of administration, palatability, dietary restriction, and minimization of disruption of daily routine. An ideal preparation does not exist and a wide variety of regimens are being used. Several of these have been investigated in pediatric clinical trials. This article reviews the published literature with an emphasis on the most commonly used agents, their mechanism of action, efficacy and ease of use, and safety.

Effect of whole gut irrigation solutions on gastrointestinal smooth muscle activity. J Pediatr Surg 2009; 44:1719-24. [PMID: 19735814 DOI: 10.1016/j.jpedsurg.2009.02.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2008] [Revised: 12/16/2008] [Accepted: 02/01/2009] [Indexed: 11/21/2022]
Abstract
BACKGROUND/PURPOSE It has been suggested that whole gut irrigation (WGI), which is a preparation method for large bowel surgery or colonoscopy, increases gastrointestinal motility by creating a gastrocolic reflex. An experimental study was performed to evaluate the effect of different WGI solutions on gastrointestinal smooth muscle activity. MATERIALS AND METHODS Thirty Wistar albino rats weighing 200 to 250 g were enrolled in the study. After anesthetization with thiopental sodium (50 mg/kg), proximal ileum, terminal ileum, and colon segments were removed via median laparotomy to obtain a control group. Four different groups (n = 6) were designated as having WGI with saline solution (SS), lactated Ringer's solution (RL), polyethylene glycol (PEG), and dibasic sodium phosphate (DNP). Bowel cleaning was performed by infusing solutions at a rate of 2 mL/min via gastric tube, until the stool was cleared. After completing the bowel cleaning, 2 cm of tissues were removed and suspended in Tyrode solution in an isolated organ bath with a resting tension of 1 g, to obtain carbachol and potassium chloride (KCl) responses. RESULTS The mean bowel cleaning times were 87.5 +/- 9.35, 81.6 +/- 9.83, 86.6 +/- 11.6, and 85.0 +/- 0.0 minutes in SS, RL, PEG, and DNP groups, respectively. The total amounts of solutions needed for cleaning were 156.67 +/- 21.6, 195.0 +/- 20.0, 197.5 +/- 32.8, and 70.0 +/- 0.0 mL, respectively. Although there was no difference in cleaning time between the groups, the amount of solution required was significantly less in the DNP group (P = .02). In the proximal ileum segments, though there was no difference in carbachol responses between groups, KCl responses were significantly increased in the RL group (P < .05). When we evaluated the terminal ileum responses, carbachol responses were significantly increased in RL and PEG groups (P = .011) and decreased in the DNP group (P = .049). The KCl responses were also significantly increased in the RL group with respect to the other groups (P < .05). Colon segments showed no difference in contractile responses with respect to different WGI solutions (P > .05, analysis of variance, post hoc Dunn's test). CONCLUSION The different WGI solutions demonstrated no significant differences in colon contractions. The increased contractile responses in the proximal and terminal ileum segments after WGI with RL may be related to the electrolyte composition of RL. Although the lower amount of DNP solution required to achieve bowel cleaning seems to be an advantage, the decreased ileal contractions can be assessed as a disadvantage of DNP irrigations.

Abstract
Total gut irrigation (TGI) is a safe method of bowel preparation in children. Many solutions are used but none is ideal. This study has been done to compare household common salt solution prepared by dissolving 10 g of pure NaCl salt (Active Reagent Quality) in 1 l of tap water, polyethylene glycol with electrolytes (PEG) and ringers lactate for TGI in children. We prospectively evaluated the three solutions in terms of efficacy, safety, rapidity, tolerability and cost effectiveness in patients undergoing a variety of colorectal procedures. Patients (126) were randomly assigned into one of the three groups; Group I, household common salt solution, 40; Group II, Peglec, 55; Group III, Ringer lactate, 31. TGI with PEG is the most rapid method of bowel preparation but is least tolerable. Household common salt solution is inexpensive and most tolerable of the three preparations. All three are similar in safety and effectiveness in bowel preparation. Household common salt solution is effective, safe, cost effective and the most tolerable method of bowel preparation.

Abstract
BACKGROUND/PURPOSE Preoperative mechanical bowel preparation (MBP) for elective intestinal operations has been a long accepted practice. However, MBP is often unpleasant and time-consuming for patients, and clinical trials in adults have not shown improved outcomes. We conducted this pilot study to test whether omitting MBP before elective intestinal operations in infants and children would increase the risk of infectious or anastomotic complications. METHODS Retrospective review was performed of 143 patients who had an elective colon or distal small bowel procedure performed at our children's hospital between 1990 and 2003. RESULTS Thirty-three patients (No PREP) were managed by a single surgeon who routinely omitted MBP, whereas another 110 patients (PREP) were prepared with enemas, laxatives, or both. Both groups received 24 hours of preoperative dietary restriction to clear liquids and perioperative parenteral antibiotics. The No PREP group had one anastomotic leak and no wound infections, whereas the PREP group had 2 anastomotic leaks and 1 wound infection (P = .58). These results occurred despite greater duration of antibiotic therapy and incidence of delayed wound closures in the PREP group. CONCLUSION The results of this pilot study suggest that omitting MBP before elective intestinal operations in infants and children carries no increased risk of infectious or anastomotic complications. Eliminating MBP may reduce health care costs and inconvenience to patients. These findings warrant a large, prospective, randomized clinical trial to validate our findings and to investigate further the necessity of MBP in the pediatric population.

Abstract
PURPOSE Although whole bowel irrigation (WBI) is a widely used method of bowel preparation in daily surgical practice, almost nothing is known about the histopathologic alterations caused by WBI and whether these differences have any detrimental effect on the outcome of gastrointestinal surgical procedures. Therefore, an experimental study has been conducted to evaluate and compare the effects of WBI with various solutions on the histology of gastrointestinal tract. METHODS During the experimental procedures animals were divided into 4 groups consisting of 8 animals each as follows: group A, WBI performed by using isotonic saline solution; group B, WBI performed by using an isoosmolar solution containing polyethylene glycol (PEG); group C, WBI performed by using Lactated Ringer's solution; group D, Animals that were not irrigated but sham operations that were performed served as controls. Four hours after WBI the animals underwent laparotomy and a segment of transverse colon with intact vascular peduncle was prepared. After waiting for 30 minutes, specimens from duodenum, small intestine, large bowel, colonic segment, and liver were obtained from each animal. Histopathologically, all of the specimens were evaluated and graded by 3 parameters including congestion, edema, and inflammation. RESULTS Although varying degrees of congestion, edema, and inflammation were encountered from all of the specimens of group A, B, and C, only slight congestion was noted in all specimens of group D. The difference between group D and other groups was statistically very significant (P < .001). When the sections from duodenums of groups were evaluated, the degree of congestion, edema, and inflammation were found to be moderate in group B, mild-moderate in group A, and mild in group C. Histopathologic examinations of specimens of the small, large bowel, and isolated colonic segment showed severe congestion, edema, and inflammation in group A, moderate-mild in group B, and mild in group C. The difference between A and B, A and C, and A and D was statistically significant (P < .01). Although severe congestion was encountered in liver specimens of group A, only mild congestion was encountered in groups B and C (P= .0001). The matched durations of irrigations and total volume of irrigation solutions were found to be not related with the difference in histopathologic findings. CONCLUSIONS WBI has induced varying degrees of histopathologic alterations from mild to severe in the rat gastrointestinal tract. Lactated Ringer's solution and PEG solution have induced the least alterations. Therefore, WBI with Lactated Ringer's solution and PEG solution seem to be safe alternatives of mechanical bowel preparation before elective large bowel surgery. Because saline solution has caused detrimental alterations in distal gastrointestinal tract histology, WBI with saline solution seems to be unadvisable.

Abstract
Whole bowel irrigation (WBI) with a polyethylene glycol electrolyte lavage solution (PEG-ELS) is a gastrointestinal (GI) decontamination procedure used after selected ingestions of toxic substances. The purpose of this study was to evaluate the ability of WBI, with and without metoclopramide pretreatment, to clear the GI tract of foreign bodies using previously established WBI end points, ie, the presence of a clear effluent or the administration of 2 L/h PEG-ELS for 5 hours. Eleven healthy, adult, male volunteers participated in this controlled, two-phase, blinded, crossover study. Ten fluorescent coffee beans were ingested after an overnight fast followed 1 hour later by 10 mg of metoclopramide syrup or an equivalent volume of placebo; 30 minutes later, WBI with PEG-ELS was begun at 2 L/h. All volunteers received 10 L of PEG-ELS during a 5-hour period. No statistically significant difference (P > .05) was found between the two pretreatments. For the metoclopramide group, the mean number of beans passed was equal to 3.8 (+/- 2.5 standard deviation [SD]; 1 to 8 R); the mean number at clear effluent was equal to 2.3. For the placebo group, the mean number of beans passed was equal to 3.5 (+/- 1.9 SD; 2 to 7 R), and the mean number at clear effluent was equal to 2.3. In conclusion, the presence of a clear effluent or the administration of 10 L of PEG-ELS are not valid markers for the termination of WBI if complete elimination of a foreign body is required. Pretreatment with 10 mg of oral metoclopramide does not enhance the efficiency of WBI.

Abstract
The authors present a report of four cases of children with posttraumatic posterior urethral stenosis who were surgically corrected through a posterior sagittal approach, with resection of the stenotic area and end-to-end anastomosis. In all cases whole colonic irrigation was used to prepare the bowel for surgery without the use of colostomy. The results were good in all cases and there were no complications. The anatomic bases of the surgical approach as well as the technical details of the procedure are analyzed, and the advantages are compared with other techniques used for the same purpose.

Abstract
A polyethylene glycol electrolyte solution was evaluated as a mechanical bowel preparation prior to surgery in an outpatient setting. Twelve children underwent outpatient bowel preparation (OPBP) prior to a variety of surgical procedures. The technique was well tolerated and consistently produced a well-prepared intestinal tract. This technique will decrease the overall cost of hospitalization, and it enhances patient and parental acceptance of mechanical bowel preparation.

Abstract
The effect of whole bowel irrigation (WBI) with a polyethylene glycol electrolyte lavage solution (PEG-ELS; 27 children) was compared to the WBI with two electrolytic solutions: normal saline with added potassium chloride (NS; 25 children) and Ringer's injection (RI; 29 children). The PEG-ELS required less volume and time, and did not cause the weight gain, hemodilution, and hyperchloremia associated with use of the electrolytic solutions. A balanced PEG-ELS is preferred in WBI of children.
