Abstract
BACKGROUND Rectal seed bezoars in children seem to present an uncommon problem that necessitates some operative intervention. PURPOSE Our objective is to determine the occurrence and clinical characteristics of rectal seed bezoars in children with fecal impaction. METHODS A retrospective review of hospital records of children with discharge diagnosis of fecal impaction was conducted from 1996 to 2005 in a university-affiliated general hospital RESULTS The study group is composed 59 children. A total of 53 had rectal seed bezoars: watermelon seeds in 43 children, prickly pear seeds in 6, sunflower seeds in 3, and pumpkinseeds in 1. Six children had seedless fecal impaction. All the children with seed bezoars were of Arab origin. Fifty children were treated under general anesthesia. Of the remaining 9 children, 5 underwent digital disimpaction without general anesthesia: 3 with seedless feces and 2 with rectal seed bezoars. Four children with rectal seed bezoars evacuated spontaneously without digital disimpaction. There was summer seasonal preference for watermelon and prickly pear seed bezoars, whereas sunflower seed bezoars occurred in the spring. CONCLUSIONS Fecal impaction owing to rectal seed bezoars is more common than previously believed. Its occurrence among Arab children alone in this study might indicate a high proportion of fecal seed bezoars throughout the Middle East. We propose that the preferred treatment should include disimpaction and irrigation of the rectal content under anesthesia. Greater awareness by primary care practitioners and parents might be beneficial in its prevention in the future.

Abstract
BACKGROUND [corrected] The megacolon is a frequent disease in our emergencie hospital, and approached in the urgency by your complications as fecal impaction, volvulus and perforations. The ulcerations in the megacolons contribute as probable sites of perforations AIM To compare the frequencies of stercoral ulceration in Chagas' megacolon operated at urgency, by volvulus or fecal impaction, and electively, aiming at a better surgical conduct in the urgency surgery METHODS It was analyzed 356 anatomy-pathological exams from colon resection of operated patients due to Chagas' megacolon at urgency (102 cases; 29%) and electively (254 cases; 71%), from 1980 to 2000. The surgical urgency indications were attributed to volvulus (71 cases; 69,6%), fecal impaction (25 cases; 24,5%), perforated acute abdomen after rectal catheter or sigmoidoscopy (6 cases; 5,9%). The ulceration frequency was compared in both groups of resections, using chi-square RESULTS The pathological anatomy - of surgery resection obtained at urgency surgeries, showed 26 cases of ulceration (25,5%) and in electively resections were verified 21 cases of ulceration (8,25%). The difference observed was statistically significant. The comparison among the groups of volvulus; fecal impaction and volvulus with fecal impaction, separately with electively surgery group evidenced significant differences in relation to volvulus and fecal impaction CONCLUSIONS The higher frequency of ulcerations in the megacolon operated at urgency character emphasizes the needs of immediate resection of sigmoid colon, instead of conservative conduct of simple decompression colostomy, even in exploration laparotomy which the macroscopic examination of sigmoid does not show necrotic signs. This way, should prevent the occurrence of perforation in megacolon at mediate postoperative, with serious results.

Abstract
PURPOSE Seed bezoars in the rectum have been considered an uncommon cause of fecal impaction in adults. Although there have been several reports on sunflower seed bezoars, seed bezoars from the fruit of the prickly pear cactus and watermelon have received little notice. This study was designed to determine the frequency of fecal impaction by seed bezoars in the rectum and their clinical characteristics in adults. METHODS A retrospective review of the medical records of patients hospitalized with the diagnosis of fecal impaction during a ten-year period. RESULTS During the study period (January 1996 to December 2005), 55 patients were hospitalized at the Western Galilee Hospital, in northern Israel, with the diagnosis of fecal impaction. Phytobezoars were found in 30 patients (55 percent). The seed bezoars were composed of prickly pear seeds in 12 patients, watermelon seeds in 10 patients, sunflower seeds in 4 patients, popcorn kernels in 1 patient, and pomegranate seeds in 1 patient. The Jew:Arab ratio for seed bezoars was 7:23. Seventy-three patients had seedless fecal masses with a Jew:Arab ratio of 58:15. All 30 patients with bezoar underwent digital disimpaction under general anesthesia. Only 21 of 73 patients with seedless fecal masses were treated under general anesthesia. CONCLUSIONS Seed bezoars found in the rectum were the most common cause of fecal impaction requiring hospitalization, probably to the result of the eating habits in the Middle East. The consumption of seeds with shell fragments or fruits containing many seeds (such as the prickly pear) should be accompanied by the awareness that large quantities may cause fecal impaction.

Abstract
OBJECTIVE Surgical treatment of constipation and obstructed defecation (OD) carries frequent recurrences, as OD is an 'iceberg syndrome' characterized by 'underwater rocks' or occult diseases which may affect the outcome of surgery. The aim of this study was to evaluate occult disorders in order to alert the clinician of these and minimize failures. METHOD One hundred consecutive constipated patients with OD symptoms, 81 female patients, median age 52 years, underwent perineal examination, proctoscopy, anorectal manometry, and anal/vaginal ultrasound. Anorectal physiology and imaging tests were also carried out when indicated, as well as psychological and urogynaecological consultation. Symptoms were graded using a modified 1-20 constipation score. Both evident (e.g. rectocele) and occult (e.g. anismus) diseases were prospectively evaluated using a novel 'iceberg diagram'. The type of treatment, whether conservative or surgical, was also recorded. RESULTS Fifty-four (54%) patients had both mucosal prolapse and rectocele. All patients had at least two occult OD-related diseases, 66 patients had at least three: anxiety-depression, anismus and rectal hyposensation were the most frequent (66%, 44% and 33% respectively). The median constipation score was 11 (range 2-20), the median number of 'occult disorders' was 5 (range 2-8). Conservative treatment was carried out in most patients. Surgery was carried out in 14 (14%) patients. CONCLUSION The novel 'iceberg diagram' allowed the adequate evaluation of OD-related occult diseases and better selection of patients for treatment. Most were managed conservatively, and only a minority were treated by surgery.

Abstract
Megacolon, resulting in severe constipation, is one of the most common manifestations of Chagas' disease. We herein report a case of megacolon with fecaloma in a 39-year-old Brazilian man who presented with severe constipation. He underwent a total proctocolectomy and ileal J-pouch anal anastomosis. Histologically, there was a marked thickening of the proper muscle layer, and a moderate decrease in the myoenteric nerve plexuses and neurons in the megacolon area. A feasible outcome has been achieved after a 1-year follow-up. A total proctocolectomy with ileal J-pouch anal anastomosis may therefore be one of the useful strategies for the surgical treatment of patients with chagasic megacolon.

Abstract
Pediatric abdominal complaints are common presentations in emergency departments, and emergency physicians are challenged every day with a vast array of gastrointestinal disorders. Differentiating the child with a benign abdominal process from the child with a more serious condition can be difficult. We report a case of massive dilatation of the colon due to fecal impaction. Means for distinguishing constipation from alternative diagnoses are discussed.

Abstract
Symptoms of fecal impaction extend from constipation, anorexia, nausea, vomiting and abdominal pain, to full blown sepsis. We present the case of a patient with cerebral palsy and mental retardation, who presented to the Emergency Department with a 3-day history of diffuse abdominal pain and fecal incontinence. Evaluation revealed severe fecal impaction. The patient developed systemic inflammatory response syndrome (SIRS), with negative workup for underlying etiology. He responded well to digital disimpaction and antibiotics. Our case illustrates the serious sequelae of fecal impaction, which should be considered in patients with neurologic disorders and SIRS.

Abstract
BACKGROUND Obstructed defaecation and faecal incontinence are complex functional disorders that pose management challenges. In recent times, the antegrade continence enema (ACE) has been tried both as a primary procedure and as a final resort to avoid a colostomy in patients with a variety of functional problems. The purpose of this study was to evaluate the role of the ACE procedure as a treatment option for adult patients suffering from obstructed defaecation with or without faecal incontinence, some of whom also had slow transit constipation. METHODS Twenty female patients underwent ACE as an appendicostomy (65%) or caecostomy (35%). The median age was 44 years (range, 20-65 years). The indications were obstructed defaecation with faecal incontinence (65%) and obstructed defaecation alone (35%). Fifteen of these patients were followed for 3-51 months (median, 6 months). Cleveland continence score, bowel score and quality of life score were recorded pre- and postoperatively along with post-procedure complications. RESULTS Thirteen (65%) patients were satisfied with the outcome and recorded improvement in their scores while two (10%) remained the same and one (5%) was worse. This latter woman and another patient stopped using their ACE, whilst follow-up data was unavailable for three patients. Minor wound infections were noted in nine patients (45%), of whom one needed drainage of an abscess; the rest settled with antibiotics and dressings. Bowel and Cleveland continence scores improved postoperatively (p<0.001 and p=0.001, respectively) but SF36 scores did not. To date, no patient has had a colostomy following an ACE procedure. CONCLUSIONS Colostomies can be avoided in patients with obstructed defaecation. There is, however, a need to minimise wound infections which seem to be the most troublesome complication.

Abstract
BACKGROUND This is the first case report of a Miami pouch sigmoid fistula developing passage of urinary stones resulting in the presentation of constipation secondary to impaction. CASE REPORT A 49-year-old woman who developed a recurrence of invasive squamous cell cervical carcinoma 1 year after pelvis radiation. She then underwent anterior pelvic exenteration and creation of a Miami pouch. Approximately 14 years after the primary radiation therapy and 13 years after the creation of the exenterative procedure, the patient developed a Miami pouch sigmoid fistula. The decision was made at this time to repair the fistula and remove the urinary stones from the sigmoid colon. Postoperatively, the patient remained continent using intermittent catheterization of the pouch and there was no evidence of recurrence of the cancer. CONCLUSION Conservative management of urinary reservoir complications should always be considered before surgical intervention is attempted. When indicated, surgical management should not be delayed.

Abstract
OBJECTIVE To call attention to constipation as a frequent sign of lichen sclerosus (LS) in girls. METHODS A focused questionnaire was sent to parents of 24 girls with anogenital LS seen in the pediatric dermatology clinic at the Children's Hospital of Wisconsin between January 2001 and May 2004. RESULTS Eighteen of 24 questionnaires were completed and returned. The average age of onset of LS was 4.2 years, but average age at diagnosis was 5.2 years; only 1 patient was diagnosed correctly by her primary care physician. Itching was the most common symptom (78%). Severe constipation was reported in 67% of patients, and 89% had at least 1 gastrointestinal complaint (bleeding with bowel movements, fissuring, soiling, fecal impaction, or constipation). CONCLUSIONS Childhood anogenital LS often presents with recalcitrant constipation or some other gastrointestinal complaint. Primary care physicians need to consider the diagnosis of LS and perform a thorough examination by looking for anogenital lesions when a female pediatric patient presents with unexplained constipation or other severe gastrointestinal complaints.

Abstract
A donkey developed abdominal discomfort and distension together with cardiovascular collapse and gastric reflux 24 to 36 hours after ingesting a large amount of poultry feed. Rectal findings prompted a laparotomy that identified extensive gastric dilation, an empty, atonic small intestine, dry colonic content and an easily corrected caecal displacement. These findings were not consistent with the severity of the signs, which were attributed to endotoxaemia. The donkey was euthanased during recovery. Necropsy revealed acute necrotising pancreatitis with massive gastric dilation and right dorsal colon impaction. The clinicopathological features of acute equine pancreatitis associated with grain overload are discussed.

Abstract
Constipation is extremely common and may affect a variety of patients from different age groups. This article outlines the causes of constipation and describes the nurse's role in the management of patients with constipation, from assessment to intervention. The skills required of the nurse, including taking a detailed history from the patient, the subsequent examination, and the administration of laxatives are discussed in detail. Nurses are best placed to assess, plan, implement and evaluate care for patients presenting with constipation. The article stresses the need for healthcare professionals to aim to prevent constipation and to identify early those patients at risk of developing constipation, to ensure that patients' needs are met fully. Recommendations for good practice are given.

Abstract
OBJECTIVE Recent evidence suggests that autistic children may have significant gastrointestinal symptoms. Although constipation occurs in 2% to 5% of healthy children, its clinical diagnosis is often difficult in children with behavioral disorders. We thus aimed to assess the prevalence of fecal loading in autistic children with gastrointestinal symptoms and to identify possible predictors of constipation. METHODS We studied abdominal radiographs of 103 autistic children (87 boys) who were referred for gastroenterological assessment, in comparison with 29 control radiographs from children who were referred to the emergency department, most with abdominal pain. Radiographs were scored independently, in blinded manner, by 4 pediatric gastroenterologists and a radiologist. The severity of constipation was determined using a validated index. Details of stool habit, abdominal pain, dietary history, and laxative use were obtained from case notes. RESULTS The incidence of constipation in the control subjects with abdominal pain was higher than reported for normal children. Despite this, moderate or severe constipation was more frequent in the autistic group than in the control subjects (36% vs 10%). Analysis of rectosigmoid loading showed more striking differences (54.4% of autistic children had moderate/severe loading or acquired megarectum compared with 24.1% of control subjects). Multivariate regression analysis showed consumption of milk to be the strongest predictor of constipation in the autistic group, whereas stool frequency, gluten consumption, soiling, and abdominal pain were not predictive of constipation. CONCLUSIONS Constipation is a frequent finding in children with gastrointestinal symptoms and autism, particularly in the rectosigmoid colon, often with acquired megarectum. The absence of any correlation between the clinical history and the degree of fecal impaction in autistic children confirms the importance of an abdominal radiograph in the assessment of their degree of constipation.

Abstract
BACKGROUND AND AIMS Prickly pear fruit rectal seed bezoars are an extremely rare entity. Only nine cases of rectal seed bezoar have been reported, only one of which involved the prickly pear fruit seed. Furthermore, to our knowledge, this is also the first reported case presenting as rectal perforation. PATIENTS AND METHODS We report a case of prickly pear fruit bezoar occurring in the elderly whom presented with rectal perforation. Consistent with physical signs, laboratory results, and radiological findings the patient was diagnosed with acute perforation of the rectum. A Hartman procedure was performed, and a colostomy was placed. RESULTS Currently there are very few data regarding seed bezoars reaching the rectum. There are even fewer data concerning this occurrence in the elderly, and the literature contains no report of this phenomenon presenting or even progressing into perforation. We report this rare entity to the existing literature. CONCLUSION We report a rare but important case. A prickly pear fruit phytobezoar presenting as rectal perforation. This case may add to the increasing awareness of the danger associated with ingestion of certain foodstuffs. The previously benign sunflower and psyllium seeds are now known to cause bezoar. We feel that the prickly pear fruit should join this small but important list.

Abstract
BACKGROUND/PURPOSE Rectal biopsies are performed as a definitive means of diagnosing Hirschsprung's Disease (HD) in children presenting with constipation. The authors hypothesized that key features in the history, physical examination, and radiographic evaluation would allow us to avoid unnecessary rectal biopsies. METHODS A retrospective analysis was conducted on patients undergoing rectal biopsy between 1995 and 2001. Patients with HD were identified (n = 50), and a concurrent cohort of patients with idiopathic constipation (IC; n = 50) was selected. Pertinent features in patients with HD versus those with IC were cross tabulated using Pearson Chi2 testing (significance was P <.05). RESULTS Sixty percent of patients with HD and 15% of patients with IC experienced onset of symptoms in the first week of life. HD patients more frequently experienced delayed passage of meconium (P <.05), abdominal distension (P <.05), vomiting (P <.05), and transition zone on contrast enema (P <.05). All patients with HD had one or more of these significant features. In contrast, only 64% of patients with IC had one or more of these features. The classic triad of symptoms (ie, delayed passage of meconium, vomiting, and abdominal distension) was present in 18%, and one or more of these symptoms was present in 98% of HD patients. In contrast, only 60% of patients with IC had a history of delayed passage of meconium, vomiting, or abdominal distension. CONCLUSIONS A history of delayed passage of meconium, abdominal distension, vomiting or the results of a contrast enema identified all patients with HD and excluded HD in approximately 36% of patients with idiopathic constipation. The authors have shown that key features in a patient's history, physical examination, and radiologic evaluation can differentiate between HD and IC. In a child presenting with constipation and none of the above features, it is not necessary to perform a rectal biopsy to exclude HD.
