JOURNAL FREE ACCESSThe purpose of this study was to investigate the risk fatcors of local recurrence and distant metastasis. Forty-four patients undergoing surgery for rectal cancer invading proper muscle were evaluated clinicopathologically. Four findings were recognized as risk factors of local recurrence, lymph node metastasis, moderately or poorly differenciated adenocarcinoma in the most invasive area of the tumor, lymhpatic vessel involvement (ly2 or ly3), and NPG type (by Shimoda's classification). Three risk factors of distant metas-tasis were also detected, lymph node metastasis, venous vessel involvement (v2 or v3), and NPG type. Two findings, lymph node metastasis and NPG type, were chosen for prognostic factors, and patients were classified into three groups, patients with no factor, with one factor, and with two factors. The cumulative 5-year survival rates were 100% in the no factor group, 87.8% in the one factor group, and 50.0% in the two factors group. Therefore, nerve preserving operation is reasonable for patients with no prognostic factor, but it is neccessary for some patients with one or two prognostic factors to undergo more wide ly-mphadenectomy or more extended surgery such as non-nerve-sparing procedure.View full abstractDownload PDF (594K) -

JOURNAL FREE ACCESSA 57-year-old female visited our hospital with the chief complaint of a large tumor incarcerating and prolapsing through the anus. Histopathologically, the biopsy specimen was villous adenoma with severe epithelial dysplasia. Both the gastrographin-enema and abdominal computed tomography confirmed the diagnosis of villous adenoma of the rec-tum.
Excision of the rectal tumor was carried out with a transanal approach in order to preserve the anal sphincter. The resected specimen was a flat elevated tumor, measuring 12.5 cm in size, which histopathologically was found to be well differenciated adeno-carcinoma in tubulovillous adenoma and was confined to the mucosa. The local excision was considered to be complete.
The patient is alive and well without recurrence of rectal cancer or anorectal strictu-re after 5 years of follow-up.
When a villous tumor of the rectum prolapses through the anus without intussuscep-tion or rectal prolapse, excision of the tumor by a tansnal approach may be appropriate because most such tumors may be confined to the mucosal layer regardless of its size.View full abstractDownload PDF (4480K) -

JOURNAL FREE ACCESSA case of appendiceal intussusception was reported. A 69-year-old female was admitted to our hospital complaining of right lower quadrant pain. A hard mass with tenderness was palpated in the right lower abdomen. Initial ultrasonographic examination of the abdomen revealed a dilated large intestine with multiple layer sign and the 5cm-sized mass in the lead. Computed tomography of the abdomen showed the lamellar structure of the large intestine and the mass with calcification. By enema study using gastrografin, the patient was diagnosed as having intussusception of the transverse colon. Subsequently, colonofiberscopy revealed a giant ulcer of the transverse colon and a protruding mass at the base of the cecum. Ultrasonography of the cecum also demonstrated a dilated appendix with multiple concentric ring sign. On laparotomy, the mass of the cecum was diag-nosed as intussusception of the vermiform appendix. This was reduced and an appendec-tomy was performed. The pathological diagnosis of the specimen was carcinoma in ade-noma of the appendix. Such a case of appendiceal intussusception with adenocarcinoma of the appendix is extremely rare. Retrospectively, preoperative ultrasonography showed the characteristic appearance of appendiceal intussusception. Although preoperative diagnosis of appendiceal intussusception is very difficult, it was emphasized that ultrasonographic examination may be valuable for diagnosis thereof.View full abstractDownload PDF (5859K) -

JOURNAL FREE ACCESSA 43-year-old male patient with analgesia and prulent discharge from the perianus was admitted to our hospital. He underwent restorative proctocolectomy with covering ileostomy for ulcerative colitis 52 months ago, and ileostomy was closed 4 months later. Perineal abscess appeared one year after ileostomy closure. Transanal and transperineal operation was performed twice for perianal fistula, but fistula recurred one month after each operation. Fistulography combined with pouchography showed a complicated fistula around the pouch originating at the anastomotic line.
Transsacral, transanal, and transperineal approaches were used to remove all fistu-la tracts. All fistula tracts could be treated under a fine surgical field, and the primary lesion was excised and resutured. Covering ileostomy was recreated. No recurrent disease has been observed 10 months since operation. The transsacral approach was considered to be an option for treating a fistula after restorative proctocolectomy.View full abstractDownload PDF (2618K) -

JOURNAL FREE ACCESSIt has been noted that a past history of cancer in the uterine body or breast is a risk factor forcolorectal cancer. A clinicopathological study was conducted to investigate the association of colorectal cancer with ovarian cancer. Six of 195 patients who underwent surgery for ovarian cancer at the department of obstetrics and gynecology between 1975 and 1985 had colorectal cancer.Histological diagnosis of the ovarian tumor was endometrioid adenocarcinoma in 4 of the 6 patients. Colorectal cancer was found in 18.2% of 22 patients with ovarian endometrioid adenocarcinoma. The association between colorectal cancer and endometrial cancer, which is characterized by Lynch syndrome II, is strong A similar relationship was suggested between colorectal cancer and ovatiam endometrioid adenocarcinoma, which had histological features similarto those of endometrial cancer,View full abstractDownload PDF (248K) -

JOURNAL FREE ACCESSTwo cases of diffuse liver metastasis of colon cancer were treated with intraarterial chemotherapy, which consisterd of continuous infusion of 5FU 250mg/day for 7 days followed by 7 drug-free days as long as popssible. CT scan showd remarkable anticancer effect one yer later : decreased number of foci and shrinkage of the rest tumor. Then partial hepatectomy was performed to remove the residual tumor masses macroscopically. Histo-pathological anticancer effect on liver metastasis were lb (1/3-2/3 of the tumor tissues were degenerated). However, they were succumbed to liver and lung metastases relapsed 2 year 6 months and 4 year 5 months later after beginning chemotherapy respectively.View full abstractDownload PDF (6137K) -
