RESUMO
A 56-year-old woman was diagnosed with rectal cancer and liver metastases(Stage IV), and underwent low anterior resection and laparoscopic partial hepatectomy. The patient received adjuvant chemotherapy(mFOLFOX6 for 24 weeks), but developed multiple lung metastases 11 months later. Before undergoing a pulmonary resection, the patient presented with acute small bowel obstruction. Abdominal computed tomography showed small bowel stenosis due to a tumor, and we suspected peritoneal metastases from the rectal tumor. We performed partial resection of the small intestine, and histopathological examination revealed a primary small bowel tumor. The patient was discharged to her home without complications, and later underwent pulmonary resections for bilateral lung metastases. We usually suspect that small bowel obstruction is due to peritoneal metastases in patients with advanced colorectal tumors, but must consider the rare possibility of a separate primary small bowel tumor, especially in patients with a solitary lesion. We report a rare primary small bowel tumor after FOLFOX treatment in a patient with Stage IV rectal cancer.

A 46-year-old woman was referred to our hospital because of nausea. Endoscopy revealed scirrhous gastric cancer, and abdominalcomputed tomography revealed peritonealdissemination. She was diagnosed with Stage IV gastric cancer and treated with S-1 plus CDDP combination chemotherapy. After 4 courses of chemotherapy, the primary tumor and peritoneal dissemination were considered clinically stable, but the uterus grew rapidly. She was diagnosed as having uterine metastasis based on cervicaland endometrialsmear class V cytology. As the chemotherapy was not effective for the uterine lesions, totalhysterectomy and bilateralsal pingo-oophorectomy were performed. Histological findings showed a poorly differentiated cancer with vascular emboli. Uterine metastases are an important consideration in women with scirrhous gastric cancer, and we recommend palliative hysterectomy for chemotherapy-resistant metastases if the primary tumor and other metastases are controlled.

Previous studies have demonstrated the safety of ABO-incompatible pediatric LDLT using preoperative plasmapheresis and rituximab; however, no reports have described the timing and dosage of rituximab administration for pediatric LDLT. This study aimed to describe a safe and effective dosage and timing of rituximab for patients undergoing pediatric ABO-incompatible LDLT based on the experience of our single center. A total of 192 LDLTs in 187 patients were examined. These cases included 29 ABO-incompatible LDLTs in 28 patients. Rituximab was used beginning in January 2004 in recipients older than two yr of age (first period: 375 mg/m(2) in two cases; second period: 50 mg/m(2) in two cases; and 200 mg/m(2) in eight cases). Two patients who received 375 mg/m(2) rituximab died of Pneumocystis carinii pneumonia and hemophagocytic syndrome. One patient who received 50 mg/m(2) rituximab required retransplantation as a consequence of antibody-mediated complications. All eight patients administered 200 mg/m(2) survived, and the mean CD20(+) lymphocyte count was 0.1% at the time of LDLT. In the preoperative management of patients undergoing pediatric ABO-incompatible LDLT, the administration of 200 mg/m(2) rituximab three wk prior to LDLT was safe and effective.

The use of donors with coagulation FIX deficiency is controversial, and there are no current protocols for peri-transplant management. We herein describe the first reported case of a pediatric LDLT from an asymptomatic donor with mild coagulation FIX deficiency. A 32-yr-old female was evaluated as a donor for her 12-month-old daughter with biliary atresia. The donor's pretransplant coagulation tests revealed asymptomatic mild coagulation FIX deficiency (FIX activity 60.8%). Freeze-dried human blood coagulation FIX concentrate was administered before the dissection of the liver and 12 h afterwards by bolus infusion (40 U/kg) and was continued on POD 1. The bleeding volume at LDLT was 590 mL. On POD 1, 3, 5, and 13, the coagulation FIX activity of the donor was 121.3%, 130.6%, 114.6%, and 50.2%, respectively. The donor's post-transplant course was uneventful, and the recipient is currently doing well at 18 months after LDLT. The FIX activity of the donor and recipient at nine months after LDLT was 39.2% and 58.0%, respectively. LDLT from donors with mild coagulation FIX deficiency could be performed effectively and safely using peri-transplant short-term coagulation FIX replacement and long-term monitoring of the plasma FIX level in the donor.

BACKGROUND: The double-stapling technique (DST) for esophagojejunostomy using the transorally inserted anvil (OrVil; Covidien Japan, Tokyo, Japan) is one of the reconstruction methods used after laparoscopy-assisted total gastrectomy (LATG). This technique has potential advantages in terms of less invasive surgery without the need to create a complicated intraabdominal anastomosis. METHODS: From 2008 to 2011, 262 patients with gastric cancer underwent total gastrectomy and reconstruction with a Roux-en-Y anastomosis, and 52 patients underwent LATG with DST. A retrospective analysis then was performed comparing the patients who experienced postoperative stenosis after LATG-DST (positive group) and the patients who did not (negative group). A comparative analysis was performed among patients comparing conventional open total gastrectomy and LATG, and multivariate analysis was performed to evaluate risk factors for the development of anastomotic stenosis. RESULTS: A minor leak was found in 1 patient (1.9 %), and 11 patients experienced anastomotic stenosis (21 %) after LATG with DST. Among the patients with anastomotic stenosis, three (3/4, 75 %) anastomoses were performed with the 21-mm end-to-end anastomosis (EEA) stapler, and eight anastomoses were performed (8/47, 17 %) with the 25-mm EEA stapler. The median interval to the diagnosis of anastomotic stenosis was 43 days after surgery. The patients with stenosis needed endoscopic balloon dilation an average of four times, and the rate of perforation after dilation was 13 %. The clinical and operative characteristics did not differ between the two groups. Anastomotic stenosis after open total gastrectomy occurred in two cases (0.98 %). Multivariate analysis showed that the size of the EEA stapler and the use of DST were risk factors for anastomotic stenosis. CONCLUSION: Esophagojejunostomy using DST with OrVil is useful in performing a minimally invasive procedure but carries a high risk of anastomotic stenosis.

Bilioenteric anastomotic stricture after liver transplantation is still frequent and early detection and treatment is important. We established the management using double-balloon enteroscopy (DBE) and evaluated the intractability for bilioenteric anastomotic stricture after pediatric living donor liver transplantation (LDLT). We underwent DBE at Jichi Medical University from May 2003 to July 2009 for 25 patients who developed bilioenteric anastomotic stricture after pediatric LDLT. The patients were divided into two types according to the degree of dilatation of the anastomotic sites before and after interventional radiology (IVR) using DBE. Type I is an anastomotic site macroscopically dilated to five times or more, and Type II is an anastomotic site dilated to less than five times. The rate of DBE reaching the bilioenteric anastomotic sites was 68.0% (17/25), and the success rate of IVR was 88.2% (15/17). There were three cases of Type I and 12 cases of Type II. Type II had a significantly longer cold ischemic time and higher recurrence rate than Type I (P = 0.005 and P = 0.006). In conclusion, DBE is a less invasive and safe treatment method that is capable of reaching the bilioenteric anastomotic site after pediatric LDLT and enables IVR to be performed on strictures, and its treatment outcomes are improving. Type II and long cold ischemic time are risk factors for intractable bilioenteric anastomotic stricture.

PURPOSE: Hepatopulmonary syndrome (HPS) is a progressive, deteriorating complication of end-stage liver disease (ESLD) that occurs in 13-47% of liver transplant candidates. Although LT is the only therapeutic option for HPS, it has a high morbidity and mortality, especially in patients with severe hypoxemia before transplantation, but the course of HPS after living donor liver transplantation (LDLT), especially for biliary atresia (BA) patients is not well established. PATIENTS AND METHODS: The present study evaluated 122 patients who received an LDLT for BA and of these, 3 patients had HPS at the time of LDLT in a single-center series. RESULTS: Two patients of the HPS patients them had biliary and/or vascular complications, but they recovered uneventfully with interventional treatment. None of the patients required supplemental oxygen and had no residual cardiopulmonary abnormalities at a follow-up of more than 24 months. CONCLUSION: Although a series of three patients is too small for definitive conclusion and further investigations must be conducted, pediatric LDLT can be a favorable therapeutic option for HPS.

PURPOSE: Bowel perforation after liver transplantation (LT) is a rare, but highly lethal complication with a poor prognosis. Here, we report the outcome of cases of bowel perforation after pediatric LT in our department. PATIENTS AND METHODS: The study subjects were 148 patients who underwent pediatric living donor liver transplantation. The 114 with biliary atresia (BA) were divided into two groups: those with associated bowel perforation (Group A) and those without (Group B). RESULTS: Four patients in all (2.5%) suffered bowel perforation. Their original disease was BA and emergency surgery was performed in all cases, with a mortality rate of 50.0%. Comparison of Groups A and B revealed significant differences in the patient age, body weight, duration of surgery, cold ischemic time, and blood loss volume. The survival rates in Groups A and B were 50.0 and 99.1%, respectively (p < 0.01). Duration of surgery was an independent risk factor (p = 0.05). CONCLUSION: Bowel perforation after LT is a potentially fatal complication. LT is a procedure that requires care and precision, and the possibility of bowel perforation should always be borne in mind during post-operative management, when the duration of surgery has been long.

CONTEXT: Although surgical resection is the only curative therapeutic option for recurrent or metachronous pancreatic carcinomas, most such cancers are beyond surgical curability. We herein report on two rare cases of remnant pancreatectomy used to treat recurrent or metachronous pancreatic carcinomas. CASE REPORTS: CASE#1 A 65-year-old male developed weight loss and diabetes mellitus 83 months after a pylorus-preserving pancreaticoduodenectomy followed by two years of adjuvant chemotherapy (5-fluorouracil plus leucovorin plus mitomycin C) for a pancreatic carcinoma in the head of the pancreas (stage IA). An abdominal CT scan revealed a 3 cm tumor in the remnant pancreas which appeared as a 'hot' nodule on FDG-PET. A remnant distal pancreatectomy was performed and a pancreatic carcinoma similar in profile to the primary lesion (stage IIB) was confirmed pathologically. CASE#2 A 67-year-old male showed increased CA 19-9 levels 25 months after a distal pancreatectomy for a pancreatic carcinoma in the body of the pancreas (stage IA). An abdominal CT scan revealed a cystic lesion in the cut end of the pancreas which appeared as a 'hot' nodule on FDG-PET. A remnant proximal pancreatectomy with duodenectomy was performed and a metachronous pancreatic carcinoma (stage III) was confirmed pathologically. CONCLUSION: Remnant pancreatectomy can be considered a treatment option for recurrent or metachronous pancreatic carcinomas. FDG-PET can play a key role in detecting remnant pancreatic carcinomas.

A 65-year-old man underwent a total gastrectomy and distal pancreatectomy for acinar cell carcinoma of the pancreas. Multiple metastatic liver lesions were found one year postoperatively. He was treated with S-1 chemotherapy over 34 months, and the tumors significantly reduced in size without severe side effects. Four years after surgery, the liver metastases increased in size, associated with pain especially in the right upper quadrant. We then performed right hepatectomy. Peritoneal dissemination and multiple lung metastases were found 8 months after liver resection. Acinar cell carcinoma of the pancreas is a rare and highly malignant tumor, and there are few reports regarding treatment with chemotherapy. Herein, we report a case with multiple liver metastases which were controlled by systemic chemotherapy using S-1.

Portal vein stenosis (PVS) after living donor liver transplantation (LDLT) is a serious complication that can lead to graft failure. Few studies of the diagnosis and treatment of late-onset (> or = 3 months after liver transplantation) PVS have been reported. One hundred thirty-three pediatric (median age 7.6 years, range 1.3-26.8 years) LDLT recipients were studied. The patients were followed by Doppler ultrasound (every 3 months) and multidetector helical computed tomography (once a year). Twelve patients were diagnosed with late-onset PVS 0.5-6.9 years after LDLT. All cases were successfully treated with balloon dilatation. Five cases required multiple treatments. Early diagnosis of late-onset PVS and interventional radiology therapy treatment may prevent graft loss.

BACKGROUND/AIMS: Laparoscopic-assisted distal gastrectomy (LADG) is a minimally invasive procedure for patients with gastric carcinoma. We have previously reported gasless LADG with a Billroth-I reconstruction using a 5-7cm minilaparotomy. We modified the technique for gasless LADG to include a Roux-en Y reconstruction and to expand the indications for its use. METHODOLOGY: A total of 40 patients with early stage gastric tumors (T1 n=38, T2 n=2) underwent this procedure. Following gasless laparoscopic distal gastrectomy with lymph node dissection, a jejunum to greater curvature of the gastric remnant anastomosis was performed using an intracorporeal laparoscopic stapled method. The jejuno-jejunal anastomosis was performed using a hand-sewn technique under direct vision through a mini-laparotomy. RESULTS: The mean surgical time (n=40) was 222 min, estimated blood loss 101 ml, and the mean number of lymph nodes harvested was 21. There were no postoperative complications such as bleeding, leak, or cardio-pulmonary dysfunction. Mean body weight loss was 3.9 kg, and there is no evidence of recurrence during a mean followup of 14 months. CONCLUSIONS: Gasless LADG with Roux-en-Y reconstruction is a feasible, novel procedure for a minimally invasive approach to gastric cancer.

A 34-year-old woman was referred to our hospital with ileus. She had undergone surgical resection following chemotherapy for yolk sac tumor at the age of 12 years, and had received additional surgery and radiation therapy for a local recurrence at age 13. Following evaluation, a sigmoid colon tumor was detected and was surgically resected. Histology proved well differentiated adenocarcinoma with chronic irradiation colitis, suggesting that irradiation may have induced the colon cancer.

Solitary mediastinal lymph node metastasis of hepatocellular carcinoma (HCC) is rare. We report a case of metachronically solitary mediastinal metastases of HCC treated by video-assisted thoracic surgery (VATS) twice. A 66-year-old man underwent repeated laparoscopic radiofrequency ablation or trans-arterial catheter chemo-embolization against HCC for more than 10 years. The level of alpha fetoprotein protein was elevated, and radiological modalities including FDG-PET revealed solitary mediastinal tumor metachronically. VATS was performed bilaterally twice. The postoperative course was uneventful and there had no recurrence of extra-hepatic metastases and tumor markers are within normal limits at 18 months after second VATS. VATS is a minimally invasive and useful procedure for solitary mediastinal lymph node metastasis of HCC. If primary HCC was controlled and lymph node metastasis was solitary, mediastinum lymphadenectomy using VATS might give good short and long term results.

BACKGROUND/AIMS: To evaluate the feasibility and usefulness of gasless laparoscopy-assisted distal gastrectomy except when treating obese patients compared with open distal gastrectomy for early cancer. METHODOLOGY: We treated 92 patients with distal gastrectomy for early gastric cancer consecutively. Patients with massive submucosal invasion and/or LN swelling were allocated for the open method, and patients with slightly invasive submucosal cancer were allocated for gasless laparoscopy-assisted surgery. As exceptions we employed open surgery for overweight patients and gasless laparoscopy for elderly and/or feeble patients. RESULTS: We attempted to perform open and laparoscopy-assisted surgery on 52 and 40 patients, respectively. Three cases in the laparoscopy-assisted group were converted to open surgery because of obesity. The age was older and BMI was lower in the laparoscopy-assisted group. In terms of operative time and blood loss as well as postoperative recovery, the results for the laparoscopy-assisted group were superior to those of the open surgery group. There were no cases of cardiopulmonary complications for the laparoscopy-assisted group. CONCLUSIONS: Gasless laparoscopy-assisted distal gastrectomy is feasible and useful for early gastric cancer except when treating obese patients.

BACKGROUND/AIMS: The purpose of this study was to assess the outcome of liver retransplantation in adults at our institution and identify the subset of patients in which the outcome was too poor to justify retransplantation. METHODOLOGY: Over a 12-year period, we performed 346 liver transplantations in 305 adult patients, and of these, 41 (11.8%) were retransplantations. Survival data were stratified and multivariate analysis was conducted to identify variables associated with poor outcome after retransplantation. RESULTS: The 90-day, 1-year, and 5-year survival rates after liver retransplantation were 65.9%, 62.6%, and 48.2%, respectively. These rates were significantly inferior compared to those following single liver transplantation. Major adverse events affecting patient survival after retransplantation occurred within the first 90 days after surgery. Three independent prognostic variables of patient survival after retransplantation were identified: preoperative coagulation factor, total bilirubin, and the need for preoperative dialysis. Using these variables, we defined a simplified mathematical model available at the time of decision of retransplantation. CONCLUSIONS: The present study indicated three important prognostic factors associated with a poor outcome after retransplantation. Based on our newly developed scoring-system estimating patient survival, we suggest that retransplantation must be indicated before the deterioration of more than two organs. These findings should assist in the decision process for liver retransplantation in adult patients.

INTRODUCTION: Laparoscopic gastric devascularization of the upper stomach in patients with gastric varices has rarely been reported. Perioperative clinical data were compared with patients who underwent open surgery. PRESENTATION OF CASES: From 2009 to 2012, we performed laparoscopic gastric devascularization without splenectomy for the treatment of gastric varices in eight patients. The patients included four males and four females. Peri-gastric vessels were divided using electrical coagulating devices or other devices according to the diameter of the vessels. Two patients underwent conversion to open surgery due to intraoperative bleeding. DISCUSSION: Intraoperative blood loss in patients who accomplished laparoscopic devascularization was very small (mean 76ml). However, once bleeding occurs, there is a risk of causing massive bleeding. CONCLUSION: With further improvement of laparoscopic devices, laparoscopic gastric devascularization without splenectomy must be an effective and less-invasive surgical procedure in the treatment of gastric varices.
RESUMO
A 76-year-old man developed jaundice and was hospitalized in January 2002. A 3 cm tumor was found in the head of the pancreas by abdominal CT, and the patient underwent laparotomy. The tumor was histologically diagnosed as a well-differentiated adenocarcinoma, and showed extensive invasion to the portal vein (T4NXM 0 Stage IV a). Incisional biopsy and hepaticojejunostomy were performed. On the basis of a drug sensitivity test, chemotherapy with 800 mg/m2/week gemcitabine was administered. The patient showed prolonged NC without any symptoms for 22 months, although the CEA and DUPAN-2 levels gradually increased during this time and massive ascites were detected in a routine abdominal CT at 22 months postsurgery. The patient died after 25 months of chemotherapy. Here we report a case of unresectable pancreatic cancer treated with gemcitabine on the basis of a drug sensitivity test.

INTRODUCTION: Radical resection of bile duct carcinoma may require resection of hepatic arteries. Preoperative segmental embolization of the hepatic artery for resection of hilar cholangiocarcinoma has been reported. We report a patient with bile duct carcinoma infiltrating the proper hepatic artery. PRESENTATION OF CASE: A 66-year old male with jaundice was diagnosed with mid-distal bile duct carcinoma. A replaced left hepatic artery originated from the left gastric artery. Pylorus-preserving pancreaticoduodenectomy (PPPD) with combined resection of hepatic artery was planned. To promote the development of collateral blood flow after excision of the hepatic artery, preoperative segmental embolization of the proper hepatic artery was performed. The patient underwent PPPD with concurrent resection of the common hepatic, right hepatic, and middle hepatic arteries without arterial reconstruction. He received adjuvant chemotherapy with gemcitabine for six months and is alive three years after surgery without tumor recurrence. DISCUSSION: The growth of collateral vessels after selective embolization of the proper hepatic artery has been used for hilar lesions and bile duct lesions. Resection of the hepatic artery without the need for complex arterial reconstruction, allowing a radical resection, may have contributed to this patient's relatively unremarkable recovery and long-term survival. Retroperitoneal mobilization of the pancreatic head and duodenum must be limited as important collaterals may originate in that area. CONCLUSION: Preoperative segmental embolization of the hepatic artery before PPPD for a patient with a replaced left hepatic artery encouraged the growth of collateral blood supply, allowing radical resection including the vessels and obviated the need for arterial reconstruction.
RESUMO
A 43-year-old Japanese man had an increasing level of serum CEA pointed out by annual physical check-ups. No abnormal findings were detected in the lungs or gastrointestinal tract. The only pathological lesions were a 1.5-cm-sized nodule in the pancreatic tail and a 5-cm-sized thyroid tumor. The thyroid tumor was shown to be medullary carcinoma by aspiration cytology. He underwent total thyroidectomy with extensive lymph node dissection. After thyroid surgery, the patient received distal pancreatectomy 2 weeks later. Pathological examination revealed the pancreatic tumor to be a metastasis of thyroid medullary carcinoma. The patient is alive and well without recurrence 5 years after thyroidectomy and pancreatectomy. The serum levels of CEA and calcitonin remain within normal limits. Thus, the patient seems to have had a solitary metastatic tumor from thyroid medullary cancer.
