Clinical and Imaging Characteristics of Herlyn-Werner-Wunderlich Syndrome: a Comprehensive Analysis.

PURPOSE: To describe the clinical and imaging characteristics of Herlyn-Werner-Wunderlich syndrome (HWWS). METHODS: This study presented an observational case series involving consecutive patients diagnosed with HWWS, whose medical records were retrospectively reviewed. From June 2012 to December 2022, there were a total of 85 patients with HWWS enrolled in our study. We obtained the medical history, including demographic characteristics, clinical presentation, treatment, complications, and radiologic examinations performed. Patients > 18 years of age (n = 58) were recontacted. RESULT: In our analysis, 27 patients were categorised as having complete obstruction, and 58 were categorised as having incomplete obstruction. The mean age at the onset of symptoms and diagnosis of complete obstruction was significantly younger than incomplete obstruction (P < 0.05). For complete obstruction, the median time between menarche and the onset of symptoms was 2.1 years, while for incomplete obstruction, it was 5.3 years. There was a significantly lower incidence of intermittent mucopurulent discharge, irregular vaginal haemorrhage, and occasional examination findings of complete obstruction than incomplete obstruction (P < 0.05). Complete obstruction was significantly associated with dysmenorrhea and pelvic endometriosis compared with incomplete obstruction (P < 0.05). CONCLUSIONS: There are distinct clinical differences between patients with complete obstruction of the hemivagina and those with incomplete obstruction. HWWS can manifest as various combinations of uterine anomalies, communications anomalies, and renal anomalies. Early recognition and treatment can avoid complications and preserve fertility. KEYSWORDS: Herlyn-Werner-Wunderlich syndrome (HWWS); complete obstruction; incomplete obstruction; obstructed hemivagina; congenital malformation.

Predictors of clinical and endoscopic findings in differentiating Crohn's disease from intestinal tuberculosis.

BACKGROUND: There are many similarities and overlaps in clinical manifestations and ileocolonoscopic features between Crohn's disease (CD) and intestinal tuberculosis (ITB). Differentiation between CD and ITB is of great importance. AIM: To investigate the values of clinical and endoscopic findings in differential diagnosis between CD and ITB. METHODS: Clinical and endoscopic features of a cohort of 130 cases of CD and 122 cases of ITB from June 2003 to February 2009 were retrospectively reviewed following predetermined criteria. Parameters were screened by logistic regression analysis. Furthermore, the diagnostic efficacy of screened parameters was analyzed by regression equation (mathematical model) and receiver operating characteristic curve (ROC curve). RESULTS: The clinical features helpful in differentiating CD from ITB are hematochezia, intestinal surgery, perianal diseases, pulmonary tuberculosis, ascites, and positive of PPD skin test; the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of regression mathematical model established by clinical features were 90.3, 76.8, 83.8, 80.7, and 88.0%, respectively. The endoscopic features helpful in differentiating CD from ITB were rectum involved lesions, longitudinal ulcer, cobblestone appearance, fixed-open ileocecal valve, transverse ulcer, and rodent ulcer; the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of regression mathematical model established by endoscopic features were 82.9, 82.0, 82.5, 82.9, and 82.0%, respectively. CONCLUSIONS: It was proposed that a diagnostic algorithm based on available clinical and endoscopic regression equation could improve the current sensitivity, specificity, and accuracy in differentiating between CD from ITB.

[Analysis of clinical characteristics of 43 surgical patients with Crohn disease using the Montreal classification].

OBJECTIVE: To investigate the clinical features of Crohn disease according to the Montreal classification. METHODS: Clinical data of 43 surgical patients with Crohn disease (surgical group) and 125 non-surgical patients with Crohn disease (non-surgical group) were retrospectively analyzed and compared between two groups. The Montreal classification was used. RESULTS: In the surgical group, 28 patients (65.1%) were A2, 14 (32.6%) were A3 and only one was A1, which was not significantly different as compared to the non-surgery group. The proportions of L1, L2, L3, and L4 subtype in the surgical group were 41.9%, 25.6%, 30.2%, and 2.3%, respectively, which was not significantly different as compared to that in the non-surgery group. In the surgical group,B1 disease was found in 1 case (2.3%), B2 in 26 cases (60.5%), and B3 in 16 cases (37.2%), while in the non-surgical group, B1 was found in 79 cases (63.2%), B2 in 44 cases (35.2%) and B3 in 2 cases (1.6%). Differences were significant between two groups in disease behavior (P=0.001, P=0.004, P=0.001). CONCLUSIONS: Most surgical patients of Crohn disease are A2. L1 and L3 are the main lesion location. As disease behavior, B2 and B3 are the main reasons for operation.
