Colorectal fecaloma is a mass of accumulated feces that is much harder in consistency than a fecal impactation. The rectosigmoid area is the common site for fecalomas and the cecum is the most unusual site. Diagnosis is usually made by distinctive radiographic findings of a mobile intraluminal mass with a smooth outline and no mucosal attachment. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, endoscopic procedures or a surgical intervention may be needed. We report here that a cecal fecaloma caused by intestinal tuberculosis scar was successfully removed by endoscopic procedures.

The treatment of constipation aims to regulate the frequency and quantity of stool in order to promote successful defecation. Numerous studies on pharmacologic treatments and non-pharmacologic therapies for constipation have attempted to overcome limitations such as temporary and insufficient efficacy. Conventional laxatives have less adverse effects and are inexpensive, but often have limited efficacy. Recently developed enterokinetic agents and intestinal secretagogues have received attention owing to their high efficacies and low incidences of adverse events. Studies on biofeedback and surgical treatment have focused on improving symptoms as well as quality of life for patients with refractory constipation.

To manage chronic constipation, dietary and lifestyle modifications should be tried before pharmacological intervention. Although there is no standardized treatment guideline for medical practice, the key considerations in the choice of laxative include the treatment duration, dosing schedule, type of agent, effects and side effects of the agent, and cost. The first-line treatment is a bulking or osmotic laxative. If the patient is still symptomatic, the physician can add or switch to other laxatives. Next, prucalopride, a highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist, could be considered. If the constipation is refractory to combination therapy with conventional laxatives and prucalopride, patients should be referred for further evaluation, including physiological testing.

The treatment for constipation should be individualized and dependent on the cause, coexisting morbidities, and patient's cognitive status. Although most cases of constipation respond to conservative treatment, including dietary and life-style changes, or mild laxatives, some patients still complain of consistent symptoms and need an assessment of defecatory dysfunction. There is insufficient evidence to support the use of enemas in chronic constipation, although many clinicians and patients find them useful and effective for the treatment of fecal impaction when used with other modalities. In addition, suppositories can be considered as an initial trial for the treatment of defecatory dysfunction, since they help to initiate or facilitate rectal evacuation. The routine use of enemas is typically discouraged, especially sodium phosphate enemas, although tap-water enemas seem safe for more regular use. Soapsuds enemas are not recommended due to possible rectal mucosal damage.

PURPOSE: To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. METHODS: Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. RESULTS: The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was 0.68±0.18 g/kg/d; according to age, the dose was 0.73±0.16 g/kg/d (<8 years), 0.53±0.12 g/kg/d (8 to <12 years), and 0.36±0.05 g/kg/d (12 to 15 years). The dose of lactulose was 1.99±0.43 mL/kg/d (<8 years) or 1.26±0.25 mL/kg/d (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). CONCLUSION: CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

BACKGROUND/AIMS: The marketing of newer agents for treatment of constipation and irritable bowel syndrome with constipation (IBS-C) emphasize improvements in abdominal pain. However, it is not clear whether this observation reflects a unique visceral analgesic effect of these agents or is a general feature of effective laxation. We sought to determine the relationship between improvements in bowel frequency and decreases in abdominal pain in clinical trials of patients with constipation or IBS-C. METHODS: We searched "PubMed" and "Embase" databanks for clinical trials in patients with constipation or IBS-C, targeting publications that provided detailed data on bowel movement frequency and pain intensity before and after an intervention. We abstracted the results and performed meta-analytic and meta-regression analyses. RESULTS: Twenty-seven trials (16 constipation and 11 IBS) met entry criteria. Baseline weekly bowel movement frequency was low with 2.35 (2.07-2.64) with differences between constipation (2.00 [1.62-2.38]) and IBS-C (2.77 [2.40-3.14]; Q = 8.18; P = 0.002). Studies reported moderate pain levels (2.12 [1.81-2.42]) with comparable baseline levels in constipation (2.02 [1.63-2.42]) and IBS-C (2.35 [2.10-2.60]; Q = 1.92; P = 0.167). Treatments increased bowel frequency by 2.17 [1.88-2.47] and lowered pain ratings by 0.58 [0.49-0.68]. Meta-regression demonstrated a significant correlation between treatment-induced increases in bowel frequency and decreased pain ratings. CONCLUSIONS: Our analysis suggests that reduction of abdominal pain observed in clinical trials of constipation and IBS-C is associated with laxation, and may not require specific drug mechanisms, thus arguing against a unique advantage of newer agents over traditional laxatives in the treatment of constipation and IBS-C.

Chronic constipation is a common functional gastrointestinal disorder that may have a significant impact on the quality of life of affected individuals. If dietary and lifestyle modifications are not successful, pharmacological interventions should be used to manage chronic constipation. The first-line conventional laxatives include bulk-forming, osmotic, and stimulant laxatives. If chronic constipation is refractory to conventional laxatives, prucalopride should be considered. The choice of a laxative should be made based on a consideration of the treatment duration, dosing schedule, type of agent, effects, and side effects of the agent, as well as cost-effectiveness. An individualized approach is needed according to the patient's underlying disease and clinical condition.

The relationship between functional abdominal pain (FAP) and occult constipation (OC) in children who did not meet the Rome III criteria for constipation has rarely been reported. This study aimed to estimate the prevalence of OC in patients with FAP and to compare the effectiveness of prokinetic drugs and laxatives for FAP and OC. Pediatric outpatients (n = 212; aged 4–15 years) who satisfied the Rome III criteria for childhood FAP were divided into 2 groups based on Leech scores: group 1 < 8; group 2 ≥ 8. Group 2 received either prokinetic drugs or laxatives and pain severity was assessed after 2 weeks, 1 month, and 3 months. A total 52.4% (111/212) of patients had OC in this study. More patients who received laxatives had reduced pain scores compared with those who received prokinetic drugs. Those treated with laxatives in group 2 had a better response than those treated with prokinetic drugs throughout the study period (P < 0.001, P < 0.001, and P = 0.002 after 2 weeks, 1 month, and 3 months, respectively). OC was frequently encountered in children with FAP. Laxatives can be more effective than prokinetic drugs for relieving symptoms of FAP in children with a Leech score ≥ 8 and suspected OC.

Constipation is a common condition affecting approximately 16.5% of population in Korea. Evaluation of constipation should be done with a history and physical examination at first. In patients with alarm sign, blood test, radiography or colonoscopy should be considered. Additionally, for defining the pathophysiology and treatment of severe constipation, physiologic studies are needed. Treatment of constipation based on the pathophysiology is generally successful. Exercise and fiber are helpful in some patients with constipation. The laxative including osmotic agent, stimulant laxatives and stool softer have been shown to be more effective than placebo at relieving symptoms of constipation. Traditional laxatives are not tolerated and are not effective in all patients with constipation. Promising drug classes, new enterokinetic agents such as 5-hydroxytyptamine-4 receptor agonists and chloride channel activators could be effective in patients with severe constipation. Biofeedback could relieve symptoms in selected patients with pelvic floor dysfunction and severe constipation. Surgical treatment could be helpful in carefully selected patients with refractory constipation.
