RESUMEN
A83 -year-old man was admitted to our hospital for the treatment of advanced ascending colon cancer with liver metastases. He had initially undergone an ileocecal resection for ascending colon cancer. Subsequently, we started oral administration of UFT/LV(UFT 400mg/day, LV 75 mg/day, and 4 weeks of therapy followed by a week suspension of treatment). After 3 courses, his tumors responded well to treatment, and CT showed marked regression of liver metastases. After 10 courses, liver metastases had almost disappeared. Two years passed without any adverse events since UFT/LV therapy was started. These findings suggest that UFT/LV therapy is very safe and effective for elderly patients with unresectable colorectal cancer.

BACKGROUND: Intersphincteric resection (IRS) is a surgical technique used to preserve sphincter function, mainly cases of low rectal cancer located less than 5 cm from the anal verge [1, 2]. There have been reports of laparoscopic ISR [3, 4], but discussion of the specific techniques used in this laparoscopic surgical procedure have not been sufficient. For better outcomes of this sophisticated procedure, extreme care must taken to prevent perforation of the rectal wall and to preserve the external sphincter muscle. The most difficult steps for ISR are the circular dissection and separation of the internal sphincter muscle from the external sphincter and puborectalis using the perineal approach. The authors' techniques and the advantages of laparoscopic ISR are shown by a video presentation of three rectal tumor cases. Also, the perioperative outcomes for the patients who underwent laparoscopic ISR with this technique are described. METHODS: From January 2006 to September 2009, laparoscopic ISR with total mesorectal excision was performed for 15 patients (10 men and 5 women). The median age of the patients was 60.5 years. The T categories of the tumor node metastasis (TNM) classification for the rectal cancers were Tis for two patients, T1 for one patient, T2 for four patients, and T3 for eight patients. The median distance from the anal verge to the tumor in this series was 3.7 cm. The Tis cases had large laterally spreading tumors that could not be removed by endoscopic submucosal dissection. The T1 case presented in the video had a small tumor just above the dentate line that had developed in the presence of chronic ulcerative colitis. Because this case required total proctocolectomy and ileal pouch anal anastomosis, local resection was not used (Table 1). Table 1 Patients' clinical characteristics (2006.1-2009.8) No. of patients: 15 Gender (M/F):10/5 Age: years (range): 60.5 (31-75) pT*: Tis (n=2), T1 (n=1), T2 (n=4), T3 (n=8) Distance from anal verge: cm (range): 3.7 (2-5) * Pathological T categories of the tumor node metastagis (TNM) classification CASES: The 68-year-old man in case 1 had a large, laterally spreading rectal tumor. The 61-year-old man in case 2 had rectal cancer, with a tumor located 4 cm from the anal verge. Laparoscopic surgery was performed after neoadjuvant chemoradiotherapy. The 71-year-old woman in case 3 had T1 rectal cancer, with a tumor located just above the dentate line. After dissection of the intersphincteric space, the prolapsing technique was used. METHODS: In the male patients, the rectum with the mesorectum was first dissected to the anal hiatus, initially on the posterior side along the avascular plane. Second, Denonvilliers' fascia was dissected, and the seminal vesicle was exposed. The third step was dissection of the lateral tissues followed by incision of Denonvilliers' fascia with the rectal wall exposure and care taken not to injure the neurovascular bundle (Fig. 1). Along this dissection plane, the puborectalis could be reached and intersphincteric space entered from the lateral side of the rectal wall (Fig. 2). The final step was dissection of the hiatal ligament at the posterior side of the rectum. Nearly circular dissection of the intersphincteric space could be completed. The difficulties associated with the perineal approach were reduced by this abdominal approach, and the tumor could be exteriorized easily. Fig. 1 After incission of the Denonvilliers' fascia at the lateral side of the seminal vesicle puborectalis muscle can be reached at the lateral side of the rectum. Fig. 2 Adhesion line between the puborectalis muscle and rectal wall is enposed. Intersphinecteric space can be entered along this dissection plane at the lateral side of the rectum. RESULTS: The mean duration of surgery was 386 min, and the mean blood loss was 108 ml. The mean postoperative hospital stay was 18 days. The diverting ileostomy was closed at a mean of 7.3 postoperative months. No remarkable perioperative complication was encountered (Table 2). Table 2 Perioperative outcomes (n=15) Duration of surgery: min (range) 386 (319-510) Blood loss: ml (range) 108 (0-180) Postoperative hospital stay: days (range) 18 (11-31) COMPLICATIONS: n (range) Anastomotic leakage 1 Stricture of the anastomosis 1 Pelvic abscess 1 Postoperative period until the stoma closure (months) 7.3 (3-16) CONCLUSION: Laparoscopic ISR enabled reduction of the difficulties associated with the perineal approach. An advantage of laparoscopic ISR is the ability clearly to visualize anatomic structures in the deep pelvic cavity.

About 50% of patients who have a permanent stoma experience some degree of parastomal hernia formation. To prevent this complication, the extraperitoneal route is considered to be more effective than the transperitoneal route in the case of open colorectal surgery. This technique also has superiority in avoiding postoperative intestinal obstruction. Although laparoscopic surgery for rectal cancer has not been proved to be as safe as open surgery by a randomized-controlled trial, some studies have shown the equality of long-term results with laparoscopic low anterior resection and laparoscopic abdominoperineal resection. It is anticipated that cases of laparoscopic abdominoperineal resection will increase in the near future. However, a laparoscopic technique for creation of a permanent stoma has hardly been discussed. Most operative procedures for laparoscopic stoma creation have been performed with transperitoneal route, which may cause parastomal hernia and/or intestinal obstruction. This report describes a laparoscopic technique for permanent sigmoid stoma creation through the extraperitoneal approach.

A 60-year-old-man underwent initial resection of a rectal tumor, with a transanal approach, on December 6, 2000. The tumor was diagnosed as a gastrointestinal stromal tumor(GIST) by KIT and CD34 immunohistochemistry. In June 2003, a third recurrence in the rectum was discovered, at the same location as the initial tumor, and he was referred to our hospital. Magnetic resonance imaging (MRI) revealed a tumor 3.0 cm in diameter, compressing the prostate anteriorly. After the oral administration of imatinib mesylate (Gleevec, Glivec) at a dose of 400 mg per day for 3 months, the size of the tumor had decreased to 1.2 cm in diameter. On December 12, 2003, a fourth operation was performed successfully, with a perineal approach, preserving sphincter function. More than 40 months after the fourth operation, neither local recurrence nor distant metastasis was detected. Our strategy of treatment with imatinib allows not only complete excision of the tumor but it also reduces postoperative impediments in patients with recurrent rectal GIST.

BACKGROUND: We have reported the efficacy and safety of S-1 combined with low-dose consecutive cisplatin therapy for advanced and recurrent gastric cancer, but the regimen was difficult because daily cisplatin administration was necessary. We have already confirmed that cisplatin of 6 mg/m2 twice-weekly maintained the same protein-bound Pt concentration as that of 3 mg/m2 of cisplatin daily. In the present study, the efficacy and safety of a combination of S-1 and low-dose twice-weekly cisplatin were investigated. PATIENTS AND METHODS: The participants were 32 patients treated at our hospital, and all were admitted for the first 2 weeks of therapy. S-1 at 80 mg/m2 daily was administered orally in two divided doses. Cisplatin at 6 mg/m2 was administered by intravenous drip infusion over 30 minutes on 2 days each week, day 1 and day 4. Each treatment cycle consisted of 4 weeks of drug administration followed by a 2-week drug-free period (6 weeks in total). RESULTS: A total of 146 cycles were administered, with a median of three cycles (range: 1-24) per patient. The results were rated as a complete response in 1 case, partial response in 24 cases and stable disease in 5 cases. The response rate was 78.1% (25/32) and the median survival time was 12.0 months (95% confidence interval (CI) 8.9-15.1 months). The response rate did not differ between previously treated and untreated patients. The one-year survival rate was 48.2% (95% CI 30.3-66.0%). The major adverse reactions were myelosuppression and gastrointestinal symptoms. The total incidence of grade 3 or greater adverse reactions was 15.6% (5/32). CONCLUSION: The combination of S-1 and low-dose twice-weekly cisplatin therapy appears to be highly efficacious and safe and shows promise as a useful treatment strategy, even in outpatient clinics.

Xanthogranulomatous changes in the pancreas are extremely rare. A 66-year-old man presented with a 2-year history of epigastralgia. Computed tomography scan revealed a 4-cm low-density area around the body of the pancreas. Magnetic resonance imaging demonstrated that the mass appeared hyperintense on a T2-weighted image and isointense on a T1-weighted image. Based on a diagnosis of invasive ductal carcinoma of the pancreas, distal pancreatectomy and splenectomy were performed. Sections examined from the mass showed an aggregation of many foamy histiocytes, lymphocytes, and plasma cells. The surrounding pancreatic tissue showed fibrosis and chronic inflammation. These findings suggested a xanthogranulomatous inflammation, and resulted in a diagnosis of xanthogranulomatous pancreatitis.

BACKGROUND: Laparoscopic surgery for colon cancer has been shown by several randomized, controlled trials to be an acceptable alternative to open surgery; however, laparoscopic rectal surgery has not been evaluated in a randomized trial. One of the most serious problems associated with laparoscopic rectal surgery are bowel clamping, irrigation, and transection of the rectum, and laparoscopic rectal surgery has not been as reliable as open rectal surgery. MATERIALS AND METHODS: We present our new technique, the laparoscopic double-stapling technique, which eliminates these problems. This technique uses curved Doyen forceps introduced through the wound just above pubis symphysis for clamping the rectal wall at the anal side of the tumor. An endolinear stapler (length 60 mm) is inserted through the same wound, applied at the rectal wall parallel and caudal to the Doyen forceps, and transects the rectum under pneumoperitoneum. We used this technique for eight cases of rectal surgery. RESULTS AND DISCUSSION: The laparoscopic double-stapling technique provided secure bowel clamping and rectal irrigation. The number of cartridges used in laparoscopic double-stapling technique cases was not more than 2, with an average of 1.6 per patient. None of the laparoscopic double-stapling technique cases experienced major complications. CONCLUSION: We consider that many cases of rectal cancer that are suitable for laparoscopic low anterior resection can undergo laparoscopic surgery by using this technique, which will improve the quality of rectal surgery.

BACKGROUND: Unresectable biliary tract carcinoma is known to demonstrate a poor prognosis. We conducted a single arm phase II study of LFP therapy (5-FU (5-fluorourasil) continuous infusion (CVI) and Low-dose consecutive (Cisplatin) CDDP) for advanced biliary tract malignancies basically on an outpatient basis. METHODS: Between February 1996 and September 2003, 42 patients were enrolled in this trial. LFP THERAPY: By using a total implanted CV-catheter system, 5-FU (160 mg/m2/day) was continuously infused over 24 hours for 7 consecutive days and CDDP (6 mg/m2/day) was infused for 30 minutes twice a week as one cycle. The administration schedule consisted of 4 cycles as one course. RESIST criteria (Response evaluation criteria for solid tumors) and NCI-CTC (National Cancer Institute-Common Toxicity Criteria) (ver.3.0) were used for evaluation of this therapy. The median survival time (MST) and median time to treatment failure (TTF) were calculated by the Kaplan-Meier method. RESULTS: Patients characteristics were: mean age 66.5(47-79): male 24 (54%): BDca (bile duct carcinoma) 27 GBca (Gallbladder carcinoma) 15: locally advanced 26, postoperative recurrence 16. The most common toxicity was anemia (26.2%). Neither any treatment related death nor grade 4 toxicity occurred. The median number of courses of LFP Therapy which patients could receive was two (1-14). All the patients are evaluable for effects with an over all response rates of 42.9% (95% confidence interval C.I.: 27.7-59.0) (0 CR, 18 PR, 13 NC, 11 PD). There was no significant difference regarding the anti tumor effects against both malignant neoplasms. Figure 2 Shows the BDca a longer MST and TTF than did GBca (234 vs 150, 117 vs 85, respectively), but neither difference was statistically significant.The estimated MST and median TTF were 225 and 107 days, respectively. The BDca had a longer MST and TTF than GBca (234 vs 150, 117 vs 85, respectively), but neither difference was statistically significant. CONCLUSION: LFP therapy appears to be useful modality for the clinical management of advanced biliary tract malignancy.

We herein report a case of rectosigmoid cancer metastasizing to a fistula in ano. A 53-year-old man complaining of anal bleeding consulted another hospital. He had been suffering from an anal fistula since 7 years. On the left upper side of the skin surface around the anus a fistula end was seen as a hole that tunneled down into the back passage, although no hard tumor was palpable on the hole. Complete colonoscopy revealed an ulcerative tumor in the rectosigmoid colon. On 5 February 2004, anterior resection and lymphadenectomy was performed. The post-operative pathological diagnosis was rectosigmoid cancer, Type 2, T2, N0, M0, stage II. The anal fistula was a simple type and mucinous discharge was not observed. On 23 February 2004, coring out the anal fistula was performed by the former hospital. Pathological diagnosis of the excised fistula revealed well-differentiated adenocarcinoma; identical to the colon tumor. Immunohistochemical staining of these two lesions were negative for (CK) 7 but staining with CK20 revealed some stained tumor cells in two lesions. We diagnosed this tumor as metastatic adenocarcinoma from a rectosigmoid cancer. Recurrent lesions were not seen during the first year after the first operation.

We herein report the case of a patient with mucinous gastric carcinoma with peritoneal dissemination that disappeared after neoadjuvant chemotherapy with S-1 alone. The patient has survived for over 23 months after surgery, without recurrence. A 60-year old man was referred to our hospital because of an advanced gastric cancer, detected by upper gastrointestinal endoscopy at another hospital. Staging laparoscopy was performed on October 25, 2002, and revealed massive peritoneal dissemination. Two courses of neoadjuvant chemotherapy with S-1 were administered, at 120 mg/day for 28 days, as one course. Total gastrectomy, with D2 lymph node dissection, was performed on January 24, 2003. The peritoneal dissemination had macroscopically disappeared and the cytology of the peritoneal lavage fluid was class III. His final diagnosis was gastric carcinoma, MLU, type 3, T2(SS), P0, H0, M0, N3, CY0, stage IV.

A 79-year-old woman presented with epigastralgia, and computed tomography showed a 3-cm multiloculated mass with a mural nodule in the head of the pancreas. Arteriography showed stenosis of the celiac artery and a saccular aneurysm, arising from the first jejunal artery. We made a preoperative diagnosis of intraductal papillary adenocarcinoma of the pancreatic head and performed a laparotomy. Transection of the median arcuate ligament failed to restore adequate hepatic blood flow, necessitating construction of celiac vascularization, achieved by a gastroduodenal to jejunal artery anastomosis. After ligation of the jejunal artery aneurysm, we performed a pylorus-preserving pancreaticoduodenectomy. Microscopically, the tumor had papillary intracystic growth, and was lined by plump cells with abundant eosinophilic cytoplasm, consistent with a diagnosis of intraductal oncocytic papillary neoplasm. We discuss this recently recognized entity of papillary neoplasm of the pancreas, and the importance of managing hepatic blood flow during pancreaticoduodenectomy in celiac artery compression syndrome.

Biliary cystadenoma in the extrahepatic bile ducts is a very rare tumor. A 62-year-old woman with jaundice was admitted to our hospital. Imaging studies revealed a 4-cm cystic lesion around the hepatic hilum, compressing the common bile duct (CBD). When laparotomy was performed, a cystic tumor was detected in the hepatic hilum, filling the lumen of the CBD. Bile duct resection that included the tumor was performed, followed by biliary reconstruction. Microscopically, the cyst wall was lined by a single layer of cuboidal epithelial cells, covering an ovarian-like stroma. The degree of atypia was low and warranted the diagnosis of cystadenoma.

Antimicrobial susceptibility of Pseudomonas aeruginosa isolated at Kochi Municipal Central Hospital between 2001 and 2003 was assessed according to the NCCLS interpretive criteria. 1. The piperacillin-susceptible rate was 92.9%. 2. Among cephem antibiotics, the ceftazidime-susceptible rate was the highest (96.0%). 3. As for aminoglycosides, susceptibility to tobramycin and amikacin remained with a susceptible rate of 93.2% and 94.8%, respectively. 4. The carbapenem-susceptibility remained high. The susceptible rate for meropenem (94.1%) was higher than that for imipenem (88.3%). 5. Acquisition of resistance was observed in urinary isolates. Four multi-drug resistant P. aeruginosa, which are resistant to all of imipenem, amikacin and ofloxacin were isolated in this study and all were isolated from urine. 6. Of 388 isolates, 34 isolates were resistant to imipenem, but no positive isolate was found in screening of metallo-beta-lactamase-producing bacteria.

BACKGROUND/PURPOSE: An aggressive approach is required to resect advanced carcinoma of the gallbladder. Therefore, an extended surgical procedure often brings about a poor surgical outcome. To test whether an aggressive surgical treatment can improve the survival rate for primary advanced carcinoma of the gallbladder, 59 patients with stage IV primary gallbladder carcinoma were studied. METHODS: Patients were divided into three treatment groups for the survival analysis: group A (resectional surgery, n = 29), group B (low-dose cis-diamminedichloroplatinum-II and 5-fluorouracil therapy, n = 10), and group C (exploratory laparotomy, other treatment modalities, or no treatment, n = 20). RESULTS: The prognosis of group A patients was significantly better than that of group B (P = 0.018) or group C (P = 0.0009). Furthermore, group A patients were divided into subgroups. The prognosis of patients resected with no distant metastasis (group A1) was significantly better than that of patients resected with distant metastases of the distant lymph nodes and the liver (group A2) (P = 0.0004). Also, there was no significant difference in the survival rate between the patients resected with distant metastasis (group A2) and chemotherapy cases (group B). CONCLUSIONS: These results indicated that radical surgery should be performed for patients with no distant metastasis, and that chemotherapy might be a useful alternative treatment for patients with distant metastasis in advanced carcinoma of the gallbladder.

BACKGROUND: In this study we evaluated the efficacy and toxicities of combination chemotherapy consisting of continuous 5-fluorouracil (5-FU) infusion and low-dose cisplatin infusion (low-dose FP therapy) in the treatment of advanced hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Thirty-eight patients with advanced HCC in whom local treatment was not indicated were enrolled. The low-dose FP therapy consisted of 5-FU (170 mg/m2/day on days 1 to 7/week, continuous infusion) and cisplatin (3 mg/m2/day in 100 ml normal saline, infusion more than 30 minutes, on days 1 to 5/weeks). The patients were treated for 4 consecutive weeks with a subsequent one-week rest period. RESULTS: Thirty-seven of the 38 patients (97%) completed this therapy. A partial response was obtained in 18 (47%), no change in 10 and progressive disease in 9. The time to progression was 211 days. The most common toxicity was nausea/vomiting (13.2%). CONCLUSION: Low-dose FP therapy has a substantial effect on low-grade toxicity in long-term treatment. Low-dose FP therapy is useful for the treatment of advanced HCC.

BACKGROUND/PURPOSE: The utility of hepatectomy for patients with metastatic liver tumors from gastrointestinal stromal tumors (GISTs) was evaluated in the present study. METHODS: Between 1989 and 2001, ten patients with liver metastases from GIST (four men and six women; age, 34-77 years) underwent hepatectomy at our hospital. All patients underwent complete resection of the primary tumor and hepatectomy with or without microwave coagulation therapy (MCT) for all detectable hepatic tumors. RESULTS: The median survival time after hepatectomy was 39 months (range, 1 to 96 months). There was one postoperative death. One patient is still alive with relapse of hepatic tumors, and the remaining eight patients died of disease (liver in six, peritoneum in one, and bone in one). Relapse of hepatic tumors occurred in seven patients. The disease-free rate after hepatectomy was 22% at 2 years and 11% at 5 years. The survival times of the four patients who received hepatic arterial chemoembolization for recurrent hepatic metastases were 7 months (still alive), 17, 23, and 28 months (average, 19 months). CONCLUSIONS: Our data suggest that aggressive surgery (hepatectomy and MCT) for all detectable hepatic tumors and hepatic arterial chemoembolization for recurrent hepatic metastases improve survival.

We report two resected cases of advanced gastric cancer with peritoneal dissemination after successful treatment with TS-1 plus low-dose CDDP. Patient 1 presented with right hypochondralgia and underwent laparotomy with diagnosis of type 4 gastric cancer by gastrointestinal fiberscopy. However, the tumor was judged to be unresectable due to peritoneal dissemination, and chemotherapy was performed. At the completion of course 1, he underwent laparotomy again. Although the tumor involved the body of the pancreas and transverse colon, there was no peritoneal dissemination. Therefore, a total gastrectomy was performed with distal pancreatectomy, partial colectomy, cholecystectomy, and D2 lymph node dissection. Patient 2 presented with anorexia and was diagnosed with type 3 gastric cancer by gastrointestinal fiberscopy. CT revealed the tumor was unresectable due to peritoneal dissemination, and so chemotherapy was performed. He underwent laparotomy at the completion of course 3. There was no peritoneal dissemination, so a total gastrectomy was performed with cholecystectomy and D2 lymph node dissection. Both patients remain alive and in good condition without any signs of recurrence after surgery.

In this study, we evaluate the efficacy of low-dose cisplatin and continuous 5-FU infusion systemic chemotherapy (LFP therapy) for the treatment of unresectable and recurrent liver metastases from colorectal cancer after weekly high-dose 5-FU therapy via the hepatic artery (WHF therapy). At the start of chemotherapy, 12 patients with multiple extrahepatic lesions were treated with the LFP therapy (LFP group), and 18 patients with none or a few extrahepatic lesions were treated with the WHF therapy followed by the LFP therapy (LFP after WHF group). In the LFP group, the response rate was 50.0% (PR 6) and the one-year survival rate was 50.0%. On the contrary, in the LFP after WHF group, the response rate was 38.9% (CR 1, PR 6) and the one-year survival rate after LFP started was 46.0%. We conclude that the LFP therapy may be effective for the treatment of liver metastases from colorectal cancer even after the WHF therapy.

BACKGROUND/AIMS: The diagnosis and treatment for hilar bile duct carcinoma has greatly improved. Frozen section is one of the modalities used to determine the intrahepatic surgical margin and the surgical approach for tumor resection. But we are sometimes faced with the case where we are perplexed whether to carry out additional surgical resection or not according to the result of frozen section, due to its inaccuracy. We studied herein the relation between the prognosis and the intrahepatic surgical margin according to the result of frozen section. METHODOLOGY: We reviewed 23 cases of hilar bile duct carcinoma whose intrahepatic surgical margin was determined by frozen section and studied the cause of death and surgical procedure. Results of the frozen sections were compared with the permanent paraffin sections. RESULTS: The overall survival rates at 1, 3 and 5 years after operation were 68.1, 41.3, and 33.0%, respectively. The accuracy, sensitivity and specificity of frozen section was 56.5%, 75.0%, and 46.7%, respectively. CONCLUSIONS: We concluded that by evaluating the diagnosis of frozen section during the surgery it was difficult to determine intrahepatic surgical margin. Aggressive hepatic resection sometimes causes a high risk of hepatic failure in which case the histological diagnosis of the frozen section throughout should not be carried out.

We evaluated the clinical effect of 5-FU and low-dose Cisplatin (LFP) therapy alone and LFP therapy combined with radiation therapy in patients with advanced or recurrent esophageal cancer. From March 1995 to September 2000, 11 patients with inoperable esophageal cancer, 8 patients with adjuvant chemotherapy post operation, and 14 patients with recurrent esophageal cancer were treated with LFP therapy. 5-FU (160 mg/m2/day) was continuously infused over 24 hours, and CDDP (3-7 mg/m2/day) was infused for 30 minutes. The administration schedule consisted of 5-FU for 7 consecutive days and CDDP for 5 days followed by a 2-day rest, each for four weeks. We combined radiation therapy for the patients with all lesions that could be included in the radiation field. Of 30 patients with measurable lesions the response rates of LFP therapy alone and LFP therapy combined with radiation therapy were 33% and 60%, respectively. Toxicity over grade 3 appeared in 3 of 15 patients with LFP therapy combined with radiation therapy. There was no significant difference between LFP therapy alone and LFP therapy combined with radiation therapy with regard to survival rate of inoperable and recurrent esophageal cancer. In conclusion, LFP therapy alone may be effective for esophageal cancer.
