Purpose Intestinal bowel endometriosis is reported in up to 37% of women with proven endometriosis. The aim of this study was to evaluate by colonoscopy and magnetic resonance imaging, patients suspected of deep infiltrating endometriosis (DIE) including the bowel wall that presented with cyclic hematochezia. Methods Twenty-four patients with cyclic hematochezia were retrospectively analyzed on colonoscopic features of colonoscopy, corresponding biopsy data, and outcome of magnetic resonance imaging evaluation. Fifteen out of 24 patients underwent bowel resection because of insufficient response to hormonal treatment (N=14) or obstructive ileus (N=1). Outcome of surgery and histologic examination of the resected specimens were evaluated. Results Colonoscopy proved intestinal endometriosis in only one out of 24 (4%) patients with cyclic hematochezia. In 13 out of 15 bowel resections endometriosis was found at histopathology. The location and dimension of lesions during surgery correlated well with magnetic resonance imaging findings. However, magnetic resonance imaging revealed a limited capacity to detect luminal narrowing of the bowel. Conclusions This study shows that colonoscopic findings of bowel endometriosis are aspecific. Colonoscopy, an invasive investigation, should therefore not be performed to diagnose endometriosis infiltrating the bowel wall. Magnetic resonance imaging provides good diagnostic work-up and in selected patients a roadmap to surgery.

Nose And Sinuses

Seventy-five patients with a wide range of sinus disease have been investigated by magnetic resonance (MR): these included congenital conditions, allergic and inflammatory sinus disease, fungus infections, and the necrotizing granulomata. In addition, a variety of benign and malignant tumours have been examined, and in the more recent sinus malignancies the paramagnetic contrast agent, Gadolinium (Gd) DTPA (Schering Health Care) has been used. This experience of magnetic resonance scanning has shown that it is superior to computed tomography in demonstrating the extent of malignant disease in the nose and sinuses; most especially when Gd DTPA is used, reaching an accuracy of over 96% by biopsy correlation. An additional advantage of this technique is the wide coverage of the head and neck for the assessment of malignant disease, provided by direct 3 plane imaging and the multislice facility. The main disadvantage of magnetic resonance of the sinuses is the poor demonstration of calcification and bone. For this reason the MR scans may need to be augmented by high resolution CT performed specifically to show bone detail.

To evaluate the accuracy of the acoustic reflection (AR) technique for determination of nasal cavity cross-sectional areas, the area-distance function of both sides of the nose was determined in 10 subjects and compared with magnetic resonance imaging (MRI). Interindividual variation for the correlation between MRI and AR was seen, but in general the areas from 1 to 6 cm into the nasal cavity measured by AR were larger than areas measured by MRI, especially where the surface was most convoluted. The total volume for this region was 6.47 +/- 1.83 (SD) cm3 for AR and 5.65 +/- 1.34 cm3 for MRI. It was demonstrated that this could be due to errors in calculation of the areas on the basis of MRI and AR. In the posterior part of the nasal cavity and the epipharynx, there was a convincingly higher correlation between acoustic measurements and a scan perpendicular to the assumed geometrical axis of the epipharynx than between acoustic measurements and coronal scanning. This indicates that the sound axis roughly follows the geometrical axis. In a model of two tubes (nasal cavities) joined in a larger tube (the epipharynx), closure of the posterior part of the latter revealed that the contralateral nasal cavity is likely to cause overestimation of the posterior part of the epipharynx during AR compared with MRI.

Introduction. To investigate the clinical results of arthroscopic management for the unstable inferior leaf of the lateral meniscus anterior horn and associated cysts through an inframeniscal portal. Methods. From March 2005 to October 2014, 64 patients with an unstable inferior leaf of the lateral meniscus anterior horn and associated cysts underwent arthroscopic management with an inframeniscal portal. The mean age of the patients was 36.9 years (range, 18 to 49 years). The mean follow-up period was 28 months (range, 24 to 44 months). Clinical results were assessed using physical examination, the Lysholm knee score, and postoperative magnetic resonance scanning. Results. The median Lysholm score improved significantly at 1 year after surgery and at final follow-up. Magnetic resonance scanning at least one year after the operation revealed no recurrent meniscal tears or cysts. No reoperations were required after an average follow-up of 28 months. All patients reported significant symptomatic relief after the operation. They had full range of motion at three months and returned to normal activities and sports one year after surgery. Conclusion. The direct inframeniscal portal can provide an effective approach to manage lesions in the anterior horn of the lateral meniscus with predictable clinical outcomes.
