Congenital markers for chronic intestinal pseudoobstruction.

OBJECTIVES: Chronic intestinal pseudoobstruction (CIP) is difficult to differentiate from true mechanical obstruction, so many patients undergo multiple operations before the diagnosis is established. This is because of a lack of easily identifiable signs and symptoms that can differentiate true intestinal obstruction from pseudoobstruction. The digital arch is the least common (10%) of the three patterns of fingerprints (arches, loops, and whorls) found in primates. Digital arches have also been reported in association with mitral valve prolapse, which in turn is associated with joint laxity. Fingerprints and mitral valve prolapse are congenital features and are influenced by heredity, so we evaluated CIP patients for coexistence of these clinical markers. METHODS: Fingerprints were examined in 1566 consecutive gastrointestinal specialty referrals. In 43 patients, the initial diagnosis of CIP was confirmed by subsequent testing. Because of the clinical impression that four features were present with increased frequency in CIP patients, these signs and symptoms were recorded prospectively: 1) number of digital arches (DA); 2) presence of mitral valve prolapse (MVP), 3) presence of joint laxity (JL), and 4) onset of constipation before age 10 (C < 10). RESULTS: Forty-three CIP patients (39 female, four male, ages 18-62) were seen. Using the test for significance of differences in proportions, the presence of DA, MVP, JL, and C < 10 proved significantly higher (p < 0.001) in CIP patients than in age- and sex-matched controls and the general population. CONCLUSIONS: We conclude that: 1) CIP may be a heritable syndrome because it is associated with heritable congenital markers (DA, MVP, JL, and C < 10; 2) these markers are identified with higher frequency in CIP patients t

Pudendal neuropathy is not related to physiologic pelvic outlet obstruction.

Chronic straining because of pelvic outlet obstruction is hypothesized to cause pudendal neuropathy (PN) by stretch injury. PURPOSE: The aim of this study was to determine any association between PN and pelvic outlet obstruction. METHODS: One hundred forty-seven constipated patients were evaluated by cinedefecography and pudendal nerve terminal motor latency assessment. PN was defined as a latency longer than 2.2 ms. Pelvic outlet obstructive patterns of evacuation included paradoxic contraction, nonrelaxation of the puborectalis muscle, or failure of opening of the anal canal. RESULTS: Median length of constipation including straining during evacuation was eight (range, 1-47) years. Ninety-one (62 percent) subjects had a normal pattern of evacuation, and 56 (38 percent) had an obstructed pattern. Both groups had a similar median age (68 vs. 69 years, respectively; P > 0.05) and same median length of symptoms. Overall incidence of PN was 23.8 percent (10.9 percent unilateral and 12.9 percent bilateral). There was no difference in the incidence of PN between patients with normal evacuation and patients with obstructed evacuation (24.2 percent vs. 23.2 percent, respectively; P > 0.05). Patients with PN had a similar incidence of physiologic pelvic outlet obstruction as did patients without PN. However, median age of patients with PN was higher than those without PN (73 vs. 66 years, respectively; P > 0.05). CONCLUSION: There was a difference in the incidence of PN between normal and obstructed patterns of evacuation. Therefore, the espoused theory that obstructed defecation causes PN appears flawed.

Duplications of the alimentary tract in infants and children.

Duplications of the alimentary tract are rare congenital anomalies that could present a diagnostic as well as therapeutic challenge. Twenty-seven patients with duplications of the alimentary tract were treated at Childrens Hospital Los Angeles between 1961 and 1992. Ages ranged from a few days to 5 years (67% younger than 1 year). The most common symptoms were nausea and vomiting, and the most common sign was a palpable abdominal mass. Three patients presented with gastric duplication, which was excised. The majority of the duplications were in the jejunum and ileum. All patients except one had primary resection of the duplication. One patient with a 45-cm tubular jejunal duplication was treated with mucosal stripping of the duplication. Five patients had cecal duplication, three patients presented with melena because of ectopic gastric tissue in the duplication, and two presented with intestinal obstruction. One of the latter patients presented with intussusception with cecal duplication as the leading point. Three patients with colonic duplication presented with abdominal pain and vomiting leading to excision of the duplication. Of the five patients with rectal duplication, three presented with chronic constipation. The other two patients presented elsewhere with perianal swelling, which eventually was drained because of a mistaken diagnosis of perianal abscess. Subsequently, these two patients came to us with persistent perineal fistula. In all our patients, rectal duplications were removed through a sacroperineal incision. The only patient in this series who died was a 6-week-old boy with gastric duplication; his death was attributed to an associated severe cardiac lesion.(ABSTRACT TRUNCATED AT 250 WORDS)
