RESUMO

AIM: To assess the results of endoscopic mucosal resection with a ligation device (EMR-L) combined with three dimensional endoscopic ultrasonography (3D-EUS) using an ultrasonic probe for rectal carcinoids. In addition, diagnosis of the depth and size of lesions by EUS was evaluated. METHODS: Between January 2003 and March 2007, 20 patients underwent EMR-L with 3D-EUS using an ultrasonic probe (group A). 3D-EUS was combined with EMR-L at the time of injection of sterile physiological saline into the submucosal layer. For comparison, 14 rectal carcinoids that had been treated by EMR-L without 3D-EUS between April 1998 and December 2002 were evaluated as historical controls (group B). EUS was conducted for all of the patients before treatment to evaluate tumor diameter and depth of invasion. The percentage of complete resection and the vertical resection margin were compared between the two groups. RESULTS: The depth of invasion upon histopathological examination was in complete agreement with the pre-operative findings by EUS. The tumor diameter determined by EUS approximated that found in the tissue samples. There were no significant differences in the gender, tumor sites or tumor diameters between the two groups. The rate of complete resection for groups A and B was 100% and 71%, respectively (P<0.05). The vertical resection margin of group A was longer than that of group B. CONCLUSION: EMR-L is effective as an endoscopic treatment for rectal carcinoids. In combination with 3D-EUS, safe and complete resection is further assured.

RESUMO

A case was 23 years old woman. She came to our hospital with complain of continuing fever after common cold and mass like an egg was touched in right lower abdomen. No other surface lymph node was swelling. Abdominal US, CT and MRI showed that the mass was existed in the front of the psoas muscle and the maximum diameter of it was 6 cm in which necrotizing lesion was recognized. The size of the lymph node became smaller slowly but we could not perfectly exclude malignant disease, we examined needle biopsy for the diagnosis. The histopathological findings showed the histiocytic necrotizing lymphadenitis (HNL). HNL usually appears in the neck area, but in this case it was detected only in the abdomen. This case was very rare and we reported.
