JOURNAL FREE ACCESSWe evaluated the response and toxicity of Nedaplatin, a new platinum analog, in patients with recurrent and advanced esophageal carcinoma, and compared with Cisplatin. Material and Method: Seven patients with organ recurrence after curative esophagectomy and 21 with nonresected advanced esophageal carci-noma (18 squamous cell, 3 undifferentiated) were treated with 1 to 6 courses of Nedaplatin combined with 5-FU. Nedaplatin (100 mg/m2) was administered intravenously on day 1 followed by continuous infusion of 5-FU (500 mg/m2) from days 1 to 5. Result: Response was 29.2% in cases of squamous cell carcinoma. By disease site, response was 57.1% for the liver including 2 CR cases, 50% for the lung and kidney, and 55.5% for the lymph node. In cases of undifferentiated carcinoma, response was 66.6%. Grade 3 and 4 thrombocytopenia were observed in 14.8% and leukocytopenia in 7.4%. Nausea and vomiting were observed in 28.6%, and 1 case dropped out due to severe vomitting. No toxic effects were observed in 28.4% of all cases. Conclusion: Combined chemotherapy with Nedaplatin and 5-FU is useful in treating organ and lymph node metastasis in esophageal carcinoma, and is more effective than Cisplatin/5-FU combination therapy in lymph node metasta-sis. Toxicity was well tolerated.View full abstractDownload PDF (85K) -

JOURNAL FREE ACCESSTo assess risk factors influencing postoperative complications from perforated duodenal ulcer in patients undergoing omental implantation, we retrospectively studied 20 cases of perforated duodenal ulcer, subdivid-ing patients with perforated into those without postoperative complications (group A; n=10, aged 21.9 and 62.9 years with a mean age of 42.3 years) or with complications (group B; n=10, aged 25.3 and 85.8 years with a mean age of 53.6 years). The postoperative complication rate was 50%. Operative motality was 10%. The most common complications were respiratory diseases. More postoperative complications were seen in group B than group A (p<0.1). Two patients over 60 years old died of uncontrolled disseminated intravascular coagulation (DIC). Durations from disease onset to surgery was less than 10 hours in group A and 72 hours in group B. Total protein concentration was significantly lower in group B than in group A (p<0.01). CRP was significantly higher in group B than in group A (p<0.01). In preoperative hepatic and renal function, electro-cardiogram (ECG), and plain chest x-ray findings, complications and mortality were more frequently in pa-tients with hepatic disfunction and abnormal chest x-ray findings. Complications and mortality were more prevalent in patients with low proteinemia and anemia. Bacterial infection involving ascites was greater in group B than in group A. The most common bacteria in ascites were Candida albicans and Klebsiella pneumo-niae. Both patients who died had Klebsiella pneumoniae in ascites.View full abstractDownload PDF (44K) -

JOURNAL FREE ACCESSThe incidence of primary duodenal cancer is low among digestive tract cancers, but since it is often diag-nosed a few considerable progression, prognosis is poor. We clinicopathologically examined for 20 patients un-dergoing resection for primary duodenal cancer. Pancreatoduodenectomy numbered 15, partial duodenal ex-cision numbered 3, and pancreatoduodenectomy with preservation of the pyloric ring numbered 2 cases. Mu-ral invasion into the pancreas was observed in 14 cases and metastasis to lymph nodes in 15. Cumulative 5-year survival was 30%. Statistical analysis revealed 4 prognotic indicators of the extent of mural invasion, me-tastasis to lymph nodes, histological classification, and invasion of veins. Pancreatoduodenectomy with preser-vation of the pyloric ring acompanied by resection of the second group of lymph nodes was the standard mode for primary duodenal cancer. Pancreatoduodenectomy was required when the degree of invasion of the stomach was high, and partial duodenal excision was sufficient to radically cure early cancer with invasion of the mucosa but no metastasis to lymph nodes.View full abstractDownload PDF (47K) -

JOURNAL FREE ACCESSPatterns of residual liver recurrence after hepatectomy were examined to determine suitable hepatectomy for liver metastasis in colorectal cancer. Positive tumor margin and no adjuvant chemotherapy via the hepatic artery (HAI) were risk factors for residual liver recurrence after initial hepatectomy. Positive tumor margin and minor hepatectomy smaller than 1 segmentectomy were risk factors for liver recurrence after a second hepatectomy. Recurrent patterns were classified into 3 types based on the location of recurrent tumors, with multiple recurrence the most common pattern after initial hepatectomy. In contrast, recurrence close to the resected surface was most common for the second hepatectomy. Chronological examination for the onset of recurrence showed that a recurrent tumor originated in the primary colorectal tumor the initial hepatectomy. Conversely, a recurrent tumotr occurred from a metastatic liver tumor after the second hepatectomy. We concluded that partial hepatectomy with tumor-free margin followed by postoperative HAI is most appropriate for the first hepatectomy. Segmentectomy or further surgery may be necessary, however, for a second hepatectomy for residual liver recurrence.View full abstractDownload PDF (58K) -

JOURNAL FREE ACCESSThis report describes about a patient who died of septicemia accompanied with massive hemolysis that occurred after surgery for gastric carcinoma. Blood culture revealed Clostridium perfringens to be the causative agent for this septicemia with acute onset and fulminant clinical course. A small liver abscess was found at autopsy with no other apparent focus of infection, so that the route of Clostridium perfringens infection was estimated to be translocation from the gastointestinal tract. Despite its rality, Clostridium perfringens septicemia with massive hemolysis should be recognized as one of possible postoperative complications following gastrointestinal operation, because prompt diagnosis followed by appropriate treatment is essential for saving the patient.View full abstractDownload PDF (61K) -

JOURNAL FREE ACCESSWe report a case of squamous cell carcinoma of stomach with multiple liver metastases. The patient was a 65-year-old woman with epigastralgia and appetite loss. Gastric cancer in the upper body of the stomach and multiple liver metastases were diagnosed. Total gastrectomy and perigastric lymph node dissection with caudal pancreatectomy and splenectomy were performed. Mitomycin C and fluorouracil were infused through the hepatic artery with a subcutaneous reservoir. The histological examination demonstrated squamous cell carcinoma. There was no evidence of adenocarcinoma in the main tumor. However, a few of the lymph node metastases showed adenocarcinoma. The pathogenesis of squamous cell carcinoma of the stomach might be squamous differentiation in a pre-existing adenocarcinoma. Liver metastases were reduced by hepatic arterial infusion. The patient is doing well 33 months after operation.View full abstractDownload PDF (91K) -

JOURNAL FREE ACCESSWe encountered a case of hepatocellular carcinoma that had invaded the gallbladder in which intraluminal bleeding caused acute abdominal pain. A 60-year-old man who was found to have an abnormal low density area on computed tomography was referred to our hospital for abdominal pain. Several examinations suggested that a gallbladder tumor had invaded the liver parenchyma and caused bleeding. Resection of gallbladder, antrum of the somach, and segment 4a and 5 in Couinaud's classification was performed. Histopathological examination showed poorly differentiated hepatocellular carcinoma. The patient died of liver failure due to multiple hepatic recurrence 54 days after the operation. To our knowledge, there are seven reported cases of hepatocellular carcinoma invaded the gallbladder. And their prognosis was poor.View full abstractDownload PDF (98K) -

JOURNAL FREE ACCESSThis report documents a patient with malignant lymphoma of the gallbladder and multiple bone metastasis. A 67-year-old woman was admitted to our hospital due to her upper abdominal pain and distention lasting 2 weeks. Abdominal ultrasonography, computed tomography (CT), drip infusion cholangiography, endoscopic retrograde cholangiography showed an irregular tumor in the fundus of the gallbladder. She underwent laparotomy and cholecystectomy, liver resection, and choledochus. Microscopic findings revealed diffuse atypical lymphocytes. Immunohistochemical staining was B-cell positive. The final pathological diagnosis was malignant diffuse large B-cell lymphoma type. The postoperative course was dismal, evidencing bone metastasis after 18 months. Malignant lymphoma of the gallbladder is extremely rare, with only 18 cases reported in Japan. All were diagnosed based on postoperative pathological findings, with no extreme symptoms and radiological findings.View full abstractDownload PDF (91K) -

JOURNAL FREE ACCESSA 75-year-old woman was referred to our hospital with hypochondriac right-abdomen pain. Abdominal ultrasonography and computed tomography showed a tumor (3cm), diagnosed as gallbladder carcinoma, in the gallbladder. Extended cholecystectomy was conducted. Macroscopically, the tumor was nodular infiltrative, 4.0×3.5cm. Microscopically, the tumor consisted mainly of small atypical cells with a high nuclear/cytoplasmic ratio forming solid cellular nests, with well-differentiated adenocarcinoma replacing the mucosa. And some of small atypical cells showed a positive argyrophil reaction and a positive result of chromogranin A. The final diagnosis was adenoendocrine cell carcinoma of the gallbladder.View full abstractDownload PDF (103K) -

JOURNAL FREE ACCESSA 71-year-old man was admitted due to abnormal gallbladder findings on echography had a papillary tumor in the common hepatic duct associated with primary sclerosing cholangitis (PSC) and intramural gallbladder cysts. Cholecystectomy and partial resection of the lateral wall of the common hepatic duct were conducted, but the cystic duct was preserved for use as a flap to cover the bile duct wall defect. Intraoperative histological examination of the common hepatic duct tumor revealed carcinoma in adenoma without tumor invasion of the surgical margin. To repair the bile duct, a cystic duct flap was made and placed over the ductal defect. Choledochojejunostomy was not done. Prevention of biliary infection and stenosis after bile duct resection is vital, especially in biliary reconstruction for bile duct cancer accompanying intrahepatic biliary stenosis such as PSC. Partial resection of the bile duct wall combined with repair of the bile duct for early bile duct cancer with PSC may thus be a useful option in avoiding postoperative biliary complications.View full abstractDownload PDF (118K) -

JOURNAL FREE ACCESSWandering spleen is a rare condition characterized by increased splenic mobility due to laxity or absence of its suspensory ligaments. We report a case of wandering spleen. A 15-year-old female was admitted to our hospital because of persistent abdominal pain after riding a roller coaster. At 13 years of age, she had come to our hospital with similar abdominal pain, but CT examination had not revealed any abnormal findings except splenomegaly. CT examination this time revealed that the spleen was not in its anatomically correct position in the left hypochondrium, but lower in the abdominal cavity. We diagnosed wandering spleen with extensive infarction by ultrasonography and angiography and performed laparoscopic splenectomy. Intraoperative inspecion revealed absence of the splenic ligaments, and histological examination showed a normal spleen with extensive infarction. The postoperative course was uneventful, and there were no signs of abdominal pain after surgery.View full abstractDownload PDF (88K) -

JOURNAL FREE ACCESSA 62-year-old man admitted to our department reported right lower abdominal quadrant pain. There was no history of previous surgery. On physical examination tenderness was localized to the right lower abdominal quadrant with associated rebound tenderness and guarding. No palpable masses were found. Abdominal x-ray revealed dilated loops of proximal small bowel with air-fluid level. Computed tomography revealed an oval, fatty paracolic mass lateral to the ascending colon, suggesting surrounding mesenteric inflammation and no appearance characteristic of appendicitis or diverticulitis. Small bowel obstruction due to epiploic appendagitis was diagnosed preoperatively. At laparotomy in emergency surgery we found inflamed appendix epiploica on the ascending colon and adhering to the mesenterium, leading to small bowel obstruction. The obstruction was relieved by lysis of adhesions. The involved appendage was excised and the stump inverted because a diverticulum was found within the appendage. Appendectomy was performed. Pathologycally, there was no inflammation in the appendix or diverticulum, therefore, we diagnosed primary epiploic appendagitis. We review 56 patients with epiploic appendagitis in the Japan literature.View full abstractDownload PDF (99K) -

JOURNAL FREE ACCESSA 41-year-old female with no surgical history was treated at our hospital in 1991 and 1993 for lower abdominal pain. When intermitent hypochondrial abdominal pain suddenly occurred on the evening of November 7, 1999, and gradually increased, she visited our department of internal medicine. Marked tenderness in the hypochondrial abdomen and increased bowel sounds were noted, but she did not exhibit rebound tenderness or muscular defense. White blood count and C-reactive protein were within normal limits. Radiography and computed tomography (CT) of the abdomen revealed a dilated small intestine with air-fluid under the diaphragm on the anterior surface of the liver. After vomiting, and a diagnosis of ileus, a nasogastric tube inserted and the woman was hospitalized. Since abdominal pain persisted despite analgesics, she was referred to the department of surgery. Due to tympanism and metallic bowel sounds in the abdomen, emergency surgery was conducted for suspected internal hernia. Marked fibrous adhesion between the liver and abdominal wall with violin string, like funicular substances enclosing the small intestine existed was observed. The small intestine was retracted and the fibrous adhesion resected, curing of the ileus. Slight inflammation in the uterine appendages was noted, and a postoperative blood sample was positive for chlamydia IgA antibody 1.38 and IgG antibody 5.41. Based on intraoperative findings, we diagnosed ileus caused by perihepatitis apparently due to chlamydia trachomatis infection.View full abstractDownload PDF (69K) -

JOURNAL FREE ACCESSA 32 years old male patient with AIDS complicated with perforation of small bowel malignant lymphoma, which was successfully treated by emergency surgery, is reported. He was diagnosed as AIDS, with a history of Candida esophagitis and an esophageal ulcer, on September 1996, and had been treated with antiretroviral drugs.
On December 1998, he had been received radiation to right maxillary lymphoma. On September 1999 pulmonary, bone, and intraperitoneal metastases were recognized and CT scan revealed an intraabdominal mass sized 6×3 cm involving the small bowel. He noted sudden onset of abdominal pain on March 2, 2000, and was transferred to the department of surgery with the diagnosis of perforation of the intestinal tract.
Perforation of malignant lymphoma of the jejunum and a total of 7 masses on small intestine were recognized during emergency surgery. Partial resection of the ileum and jejunum including the perforated segment, drainage, and jejunostomy were performed. Pathologically the tumor was non Hodgkin's lymphoma, B cell type. The postoperative course was uneventful, but he was died of malignant lymphoma on 143 days after the surgery.View full abstractDownload PDF (218K) -

JOURNAL FREE ACCESSPrimary malignant lymphoma of the small intestine is next highest in frequency following the stomach. Burkitts'primary malignant lymphoma (Burkitts'lymphoma) of the small intestine is rare, as are cases leading to leukemic transformation, only 2 of the latter have been reported in Japanese including our case. Additionally, our case showed anormaly of chromosome. An 83-year-old woman was referred to our department due to melena during admission for a fractured left femur. A mass 10 cm in diameter with tenderness was palpated on right lower abdomen. She was diagnosed with malignant lymphoma of the cecum by abdominal computed tomography (CT) and colono fiberscopy and ilececal resection was done. The resected specimen showed a tumor at the terminal ileum with a “starry sky” appearance microscopically, so she was diagnosed with Burkitts'lymphoma of the ileum. Two weeks after surgery, her general condition worsened. Blood tests showed extremely elevated white blood cell count and the occurrence of lymphoblasts. She was diagnosed with leukemic transformation and started on chemotherapy, but the disease progressed and she died 3 weeks postoperatively.View full abstractDownload PDF (91K) -

JOURNAL FREE ACCESSA 70-year-old man was admitted to our hospital for ascending colon cancer reported headaches before being transferred to our surgical floor. Brain CT showed no metastasis to the brain but showed sulcal enhancement of the cerebellum. Laparotomy revealed ascending colon cancer with diffuse lymph nodes metastases and peritoneal dissemination. We suspected that the patient had meningeal carcinomatosis because he became somnolent after postoperative day (POD) 3. A lumbar puncture showed spinal fluid contained cancer cells. The clouding of consciousness and liver dysfunction were progressive and he died on POD 12.
Meningeal carcinomatosis is rare in carcinoma of the colon, and many cases involve highly advanced cancer and a relatively poor prognosis.View full abstractDownload PDF (104K) -

JOURNAL FREE ACCESSA 49-year-old man with anemia was found in endoscopic examination to have a subpedunculated polypoid tumor in the descending colon. The top of the tumor was white, lustrous, and movable with almost normal mucosa. We suspected it as a cancer of the descending colon and conducted left hemicolectomy. Macroscopically, the tumor was 22×18 mm and elastically soft. Microscopically, it showed proliferation of uniform atypical lymphocytes with hyperchromatic unclei in the superficial layer of the tumor head. Singularly, the tumor had hyalinofibrous connective tissue in the center of the head and peduncle. Immunohistochemically, tumor cells were positive to T-cell markers (CD3, MT1) and negative to B-cell markers (L26, MB1). The tumor had invaded the submucosal layer without lymph node metastasis and was diagnosed as non-Hodgkin's lymphoma, diffuse medium cell, T-cell in LSG. This case case was extremely rare, since it involved the descending colon, was subpedunculated, was early lymphoma, and was T-cell.View full abstractDownload PDF (113K) -

JOURNAL FREE ACCESSA 69-year-old man underwent colonoscopy due to a positive fecat occult blood test and a sessile polyp with central depression in the rectosigmoid area was found. Endoscopic mucosal resection was conducted piecemeal. Histological examination of the endoscopic resected specimen showed cancer invasion with mucous nodules into the deep submucosal layer. The patient was referred to our hospital and additional anterior resection of the rectum was conducted. Histological examination revealed no residual cancer cells and several mucous nodules in the submucosal layer. Endoscopic mucosal resection as complete biopsy is thus useful, but piecemeal resection may make it difficult to evaluate cancer invasion into the submucosal layer and metastasis risk. When endoscopically removed specimens histologically show mucous nodules, we strongly recommend surgical resection with lymph node dissection.View full abstractDownload PDF (74K) -

JOURNAL FREE ACCESSA 59-year-old man with 30-year history of anal fistula was admitted to our hospital reporting a growing perianal tumor. At the right side of the anus, the tumor was palpable, at 5 cm in diameter. Pus was discharged from the fistula through the tumor. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an abcess and fistula beside the tumor. Rectal cancer was found 10 cm from the anus by colonoscopy. A biopsy was done and revealed moderately differentiated adenocarcinoma. We conducted abdominoperineal resection (D2) for the perianal tumor and resected right inguinal lymph nodes. The anal defect was repaired with a gracilis myocutaneous flap. The perianal tumor showed the same histological appearance as the rectal cancer, so we concluded that free tumor cells from the rectal cancer may have been implanted in the anal fistula.View full abstractDownload PDF (91K) -

JOURNAL FREE ACCESSFour patients, aged 63-72 years, with small hepatocellular carcinoma (HCC) were treated with computed tomography (CT)-guided percutaneous microwave coagulation therapy (PMCT). Not all tumors were demonstrable by sonography due to their size or tumor location. All patients had a solitary HCC nodule in the right hepatic lobe from 9 to 20 mm in diameter. Three had HCC nodule recur after surgery. All received transcatheter arterial embolization using Lipiodol. All nodules were represented as Lipiodol spots on subsequent CT serving as marker for CT-guided localization and needle puncture. Distances between the skin puncture point and target nodules ranged from 27 to 62 mm. Tumor puncture with a fine needle and subsequent placement of the PMCT needle were without complication. All treated nodules were surrounded by non attenuated areas on dynamic CT using contrast enhancement, indicating complete tumor necrosis. No local recurrence was seen in the treated lesions. Three patients are still alive and died of multiple intrahepatic HCC recurrence. In conclusion: CT-guided PMCT is useful for in detecting small HCCs not found by sonography.View full abstractDownload PDF (54K) -
