JOURNAL FREE ACCESSPURPOSE: The aim of this study was to assess the accuracy of preoperative magnetic resonance imaging for the prediction of external anal sphincter invasion and para-external anal sphincter muscle invasion in lower rectal cancer patients.
METHOD: Twenty-six patients with lower rectal cancer who underwent curative abdomino-perineal resection were investigated. The para-external anal sphincter invasion was defined when tumor was observed within 1mm from the inter rim of the external anal sphincter muscle. We established the criteria for external anal sphincter invasion on magnetic resonance imaging. Preoperative magnetic resonance imaging was compared with pathological results prospectively.
RESULT: External anal sphincter invasion was seen in only two patients, and para-external anal sphincter invasion was seen in 7 of the 26 patients histologically. Accuracy of preoperative magnetic resonance imaging for detecting external and para-external anal sphincter invasion was a sensitivity of 89% and a specificity of 82%.
CONCLUSION: Preoperative magnetic resonance imaging could be useful for detecting external and paraexternal anal sphincter invasion in rectal cancer patients.View full abstractDownload PDF (3328K) -

JOURNAL FREE ACCESSWe investigated 144 patients of colorectal cancer with macroscopic invasion into the adjacent organs (Si⋅Ai) to find a determinant of therapeutic choice. Primary lesions were resected in 115 cases, and in 49.6% of them, macroscopic diagnosis was consistent with histological diagnosis. The cases of Si⋅Ai were frequently detected among poorly differentiated and mucinous adenocarcinoma according to histopathological types, and the rate of consistency of macroscopic diagnosis with histologic diagnosis was high in such carcinomas. The survival rate of Si⋅Ai cases showed that the patients with a high cure rate had a good prognosis. In Cur A cases, the survival rate was similar in Si⋅Ai cases and SS⋅SE⋅A1⋅A2 cases when lymph node metastasis was n0 and n1, but the survival rate was poorer in Si⋅Ai cases than in SS⋅SE⋅A1⋅A2 cases with n2-3 metastasis. Although aggressive extensive resection should be performed in patients with Si⋅Ai, surgical therapy is not sufficient for the treatment of such cases with n2-3 metastasis.View full abstractDownload PDF (361K) -

JOURNAL FREE ACCESSWe investigated the incidence and clinical course of extraintestinal manifestations (EIM) in 233 patients with ulcerative colitis (UC) and 233 patients with Crohn's disease (CD) who underwent abdominal surgery in our department. One hundred and three patients with UC (44.2%) and 99 patients with CD (42.5%) exhibited one or more ElMs. Cholelithiasis was the most frequently observed EIM and occurred in 28 patients with UC (12.0%) and in 29 patients with CD (12.4%). About 70% of cholelithiasis occurred after abdominal surgery in patients with UC as well as with CD. In patients with CD, cholelithiasis was more frequent in patients with ileitis than in patients with ileocolitis (p<0.05) or patients with colitis (not significant). As for specific ElMs to CD, vitamin or trace element deficiency was found in 20 patients with CD (8.6%). In patients with UC, peripheral arthritis, pyoderma gangrenosum and uveitis were frequently observed EIMs, which developed in 20 (8.6%), 16 (6.9%) and seven patients (3%), respectively. Most of the cases of pyoderma gangrenosum and uveitis improved after total colectomy. However, most of the cases of peripheral arthritis deteriorated or developed after total colectomy. For surgical therapy of UC or CD, it is important to know well the influence of bowel resection on the clinical course of EIMs.View full abstractDownload PDF (558K) -

JOURNAL FREE ACCESSA 48-year-old man visited our hospital complaining of high fever and systemic eruption. With swelling, redness and ulcerations of the scrotum, he was diagnosed as Fournier's gangrene and treated by incision and drainage. He had been occasionally treated in the same way for Fournier's gangrene. As severe anemia was pointed out, further examination for the cause of anemia was done and he was diagnosed as myelodysplastic syndrome (MDS RA type).
He was readmitted for therapy of recurrent Fournier's gangrene. After incision of the scrotum and castration, complication with panperitonitis due to perforation of the gastrointestinal tract was found. Multiple small punched-out ulcerations at the small intestine were revealed and ileocecal resection was performed. Postoperative colonoscopy revealed intestinal Behçet disease for multiple ulcerations and scars at the small and large intestine. He has been receiving home parenteral nutrition. Here we summarize 36 cases of Behçet disease associated with MDS in Japan.View full abstractDownload PDF (2836K) -

JOURNAL FREE ACCESSWe report a case of descending colon cancer which formed a colocolic fistula and jejunocolic fistula at the same time. A 73-year-old woman visited our hospital because of left lower abdominal tumor and anemia. We made a diagnosis of descending colon cancer with suspected fistulation into the transverse colon and small intestine. Upon laparotomy, the tumor had infiltrated the transverse colon and the jejunum 40cm on the anal side from the Treitz ligament. Left hemicolectomy and partial resection of the jejunum were performed. On the resected specimen, fistula formation into the transverse colon mucosa and jejunal mucosa was revealed. Histopathological study showed moderately differentiated adenocarcinoma, without lymph node metastasis. The incidence of colon cancer with fistula formation in other intestine is very rare. This is the first report of a synchronous complicated case of colocolic fistula and jejunocolic fistula.View full abstractDownload PDF (5711K) -

JOURNAL FREE ACCESSIntestinal malignant peripheral nerve sheath tumor (MPNST) is a very rare disease. We report a case of MPNST of the rectum. A 71-year-old female came to our department because of constipation. Barium enema showed irregular narrowing of the rectum. Colonoscopic examination demonstrated rectal tumor 10cm from the anal verge. Biopsied specimens revealed neurilemmoma, but CT and MRI showed the rectal tumor invading to the uterus and the right ureter. Therefore we speculated malignancy. Low, anterior resection with hysterectomy, bilateral salpin-goophorectomy and the right lower part ureterectomy was performed. Histologically, atypical tumor cells were seen closely in deep layer, and then diagnosed as MPNST. There are no signs of recurrence 12months after the operation.View full abstractDownload PDF (3472K) -
