Endometriosis is a rare disorder characterized by the presence of endometrial mucosa abnormally implanted in locations other than the uterine cavity. A 38-year-old woman who was admitted after complaining of abdominal pain and abdominal distention for three months underwent abdominal CT which revealed a tumor in the ileocecal area. Abdominal pain occurred during the menstrual cycle. Laboratory data revealed elevation of CA125. We performed ileocecal resection. Pathologically, ileocecal endometriosis with lymphovascular involvement was diagnosed. This case of intestinal endometriosis suggested lymhogenic progression. © 2014 The Japanese Society of Gastroenterological Surgery.

© 2014 Elsevier Ltd. All rights reserved. Background: Prognostic influences of hepatic transection by an anterior approach using the liver hanging maneuver (LHM) has not been fully clarified. Methods: We examined 233 patients who underwent major hepatectomy with the LHM (n = 75; hepatocellular carcinoma (HCC) in 35, colorectal liver metastasis (CLM) in 10, intrahepatic cholangiocarcinoma (ICC) in 14 and perihilar bile duct carcinoma (BDC) in 16) or without it (n = 158; HCC in 78, CLM in 21, ICC in 31 and BDC in 28). Results: In HCC patients, cancer-positive margin rate, blood loss, transection time and prevalence of posthepatectomy ascites in the LHM group were significantly lower than those in the non-LHM group (p < 0.05). In CLM, transection time in the LHM group was significantly lower than that in the non-LHM group (p < 0.05). In BDC patients, amount of blood loss, transection time and prevalence of ascites in the LHM group were significantly lower than those in the non-LHM group (p < 0.05). In CLM patients, tumor recurrence rate in the non-LHM group was significantly higher than that in the LHM group and disease-free survival in the LHM group was significantly better than that in the non-LHM group in CLM patients and, however, this difference was not observed in a large CLM exceeding 5 cm. However, significant differences of posthepatectomy disease-free and overall survivals were not observed in HCC, ICC and BDC patients. Conclusions: Although advantages of LHM improving surgical records in major anatomical liver resections were clarified, oncological advantages in the long-term survival of LHM was still uncertain in the hepatobiliary malignancies.

© 2015, Nagasaki University School of Medicine. All rights reserved. Endoscopic submucosal dissection (ESD) is a standard treatment for early gastric cancer, but it is not generally used for colorectal lesions because of its high risk of adverse events. An unanticipated adverse event of rectal ESD is reported. A 71-year-old man was found to have a laterally spreading tumor at the upper rectum. ESD was performed. During the ESD, rectal perforation occurred, and emergency laparoscopic surgery was performed. At the operation, rectal perforation with retroperitoneal emphysema was detected. Surprisingly, an 8-cm-long, lacerated wound was found at the cecum wall. It was thought to have been caused by heat injury due to ESD. The perforated site was resected, and the laceration of the cecum was repaired by extracorporeal suture. In patients with perforation during ESD, it is essential to keep in mind that other organs might have heat-induced injury, and the patient should be more carefully followed.

Background: Photodynamic therapy (PDT) is an effective laser treatment for locally advanced carcinoma and is promising as neoadjuvant chemotherapy before surgery. The aim of this study was to clarify the adverse effects of PDT using a photosensitizer, talaporfin sodium (Laserphyrin®), for wound healing. Methodology: For PDT, a laser light with a wavelength of 660 nm and a frequency of 10 Hz with a total energy fluency of 60 J/cm 2 was used. Macroscopic and histological findings of wound healing after PDT were examined in vivo (4-week-old male BALB/c mice). Results: In Model 1, in which skin was cut at 0, 3, 7 days after PDT (n=3, each), wounds were similarly healed 7 days after cutting in all groups, and regenerating epithelium and the number of fibroblasts on histological findings were not different. In Model 2, in which skin defects were created before or after PDT, the size of the defects was larger at day 7 in the groups with skin defects before or after PDT in comparison with groups with no PDT. However, macroscopic wound healing at day 14 was complete in all groups and there were no significant differences among the groups by this point. Histological findings of skin defects at day 14 showed no significant difference in terms of regenerating epithelium and number of fibroblasts in each group with or without PDT. Conclusions: PDT did not influence wound healing and can be safely applied before surgical therapy. © 2006-2012 Nagasaki University Library.

Desmoplastic small round cell tumor (DSRCT) is an uncommon, poor prognostic tumor which is found mainly in young adults. A 23-year-old woman was admitted to our hospital with a complaint of anal pain. Pelvic CT revealed a 50-mm tumor in the anal and swollen lymph nodes in the bilateral inguinal region. DSRCT was diagnosed by biopsy, and Mile's operation with bilateral inguinal lymph nodes dissection was performed. Though adjuvant radiation was performed to prevent recurrence of the disease, 6 months later, she experienced multiple distant metastasis. She was treated with multiagent chemotherapy (18 courses of VDC-IE, 13 courses of gemcitabine/docetaxel) which inhibited tumor growth for long periods. Here, we report a case of perianal DSRCT. © 2013 The Japanese Society of Gastroenterological Surgery.

Background Acinar cell carcinoma (ACC) is a very rare malignancy and represents only 1% to 2% of pancreatic exocrine carcinomas. At the time of diagnosis, 75% of ACC are resectable. Reliable data concerning effective adjuvant chemotherapy has not been established. Case presentation A 30-mm tumor in the pancreatic tail was incidentally discovered by computed tomography in a 71-yearold man. Several swollen lymph nodes were seen around the main tumor. Endoscopic retrograde cholangiopancreatography (ERCP) revealed disruption of the main pancreatic duct. The patient underwent curative resection (R0) with distal pancreatectomy and node dissection. Histopathological examination revealed ACC with lymph node metastases; adjuvant chemotherapy was performed with gemcitabine after surgery. Twelve months later, the patient showed no sign of recurrence. Conclusion The prognosis of ACC is dismal, although compared to ductal adenocarcinoma, the mean survival appears to be longer. Patients with advanced-stage ACC might benefit from gemcitabine-based adjuvant chemotherapy.

Although the protein-induced vitamin K absence or antagonist-II (PIVKA-II) is used as a prognostic marker in hepatocellular carcinoma (HCC), a newly-improved assay, NX-PVKA (PIVKA-II measured using P-11 and P-16 antibodies) and NX-PVKA-R (ratio of PIVKA-II and NXPVKA), are more accurate markers of PIVKA-II. We conducted a prospectively preliminary analysis of the relationship between NX-PVKA-R and clinicopathological parameters and prognosis in 22 patients with HCC who underwent hepatectomy and measured changes of this marker's levels after treatment. Median value of PIVKA-II (80 mAU/ml), NX-PVKA (60 mAU/ml), NX-PVKA-R (1.5) and NX-PVKA-D (difference of markers, 15 mAU/ml) were determined. Tumor relapse was observed in six patients, and the one year relapse-free survival rate was 88%. Correlation between PIVKA-II or alpha-fetoprotein levels and NX-PVKA, NX-PVKA-R or -D levels was significant (p < 0.001). NXPVKA- R was significantly correlated with tumor size (p < 0.05). In patients who underwent pre-treatment before hepatectomy, PIVKA-II, NX-PVKA and NX-PVKA-R tended to be higher than in patients without pre-treatment, but this difference was not significant (p > 0.10). For macroscopic findings, NX-PVKA-R for the confluent-nodular type was significantly higher than that for the simple-nodular type (p < 0.05). The tumor-free survival rate in the group with a high NX-PVKA-R was significantly lower than that in the group with a low NX-PVKA-R group (p < 0.05). In patients with tumor recurrence, postoperative NX-PVKA-R increased again. We conclude that a high value of NX-PVKA-R after hepatectomy for HCC reflects malignant potential and predicts early recur rence in patients with HCC.
