    ABSTRACT: To determine whether clinical outcomes after proximal gastrectomy are better than those after total gastrectomy with Roux-en Y reconstruction. We studied 10 consecutive patients with early gastric cancer who underwent esophagogastrostomy after proximal gastrectomy (PG group). Nutritional variables in these patients were compared with those in 10 consecutive patients who underwent Roux-en Y reconstruction after total gastrectomy (TG group). Patients were followed up for 5 years after operation. There was no anastomotic leakage. The total cholesterol level 1 year after operation was higher in the PG group than in the TG group (p< 0.05). Body mass index was significantly lower than the preoperative value between 1 month and 2 years postoperation in the PG group, whereas the TG group showed decreases between 3 months to 5 years postoperation. The percent decreases in body weight at 3 and 4 years in the PG group were lower than those in the TG group (both p< 0.05). Postoperative weight loss was thus milder in the PG group than in the TG group. Esophagogastrostomy after PG may produce better clinical outcomes than Roux-en Y reconstruction after TG in patients with early gastric cancer arising in the upper third of the stomach.

    ABSTRACT: This study was designed to assess the outcome of esophagogastrostomy before proximal gastrectomy in patients with early gastric cancers in the upper third of the stomach. From 1997 through 2004, we studied 10 consecutive patients. A stapler was introduced into the stomach, and an esophagogastrostomy was performed before proximal gastrectomy. Hill's posterior gastropexy and Dor's anterior fundic wrap were performed to prevent reflux esophagitis. The operation time was 171 ± 44 minutes, and the intraoperative bleeding volume was 294 ± 228 mL. There was no anastomotic leakage. Anastomotic stenosis, occurring in 40% of the patients, required endoscopic balloon dilatation. Symptoms of reflux esophagitis, occurring in 40% of the patients, resolved within 2 years after operation. As compared with the preoperative value, body mass index was significantly decreased 1 and 2 years after operation, but was similar at 3 to 5 years. The percent decrease in body weight after operation fluctuated between 6% and 8% between 2 and 5 years. Postoperative weight loss was thus mild. Esophagogastrostomy before proximal gastrectomy may be less invasive, simpler, and produce better outcomes than conventional procedures for the surgical treatment of early gastric cancer in the upper third of the stomach.

    ABSTRACT: A 47-year-old woman presented with an abdominal mass and nausea. Abdominal ultrasound and computed tomography (CT) showed a sausage-shaped mass with invagination. One polyp that appeared to exceed 3 cm was found in the sigmoid colon. Laparoscopy confirmed an intussusception mass, and the intussusception was dissected by hand-assisted laparoscopy (HALS). The sigmoid colon was also mobilized to the site of the small incision and resected. Generally, we believe enterectomy including polyps should be avoided as much as possible in Peutz-Jeghers syndrome (PJS) because poly-surgery may lead to short bowel syndrome. In addition, PJS patients often undergo multiple surgery, and therefore dense intra-abdominal adhesions are seen at subsequent laparotomy, which makes surgery increasingly difficult with repeated operations. Laparoscopic-assisted surgery seems beneficial, as in the present case.

    ABSTRACT: To assess the roles of the extent of gastric resection and duodenal food passage reconstruction in gastric cancer, we examined a consecutive series of 1,061 patients who underwent total or partial (proximal and distal) gastrectomies with or without duodenal food passage reconstruction between August of 1974 and January of 2002, and received gastrectomies with D2-3 lymph node dissection. Patients who underwent distal or proximal gastrectomy were found to have significantly better survival rates than those who underwent total gastrectomy in stages 1A (10-year survival: 86.6 and 78.9 vs. 61.6%), 2 (56.5 and 65.6 vs. 34.4%), 3A (45.9 and 33.3 vs. 15.2%), and 4 (5-year survival rates: 23.7 and 50.0 vs. 7.1%). Additionally, patients with duodenal food passage reconstruction or double tract reconstruction also showed significantly better survival rates than those without duodenal food reconstruction in stages 1A (10-year survival: 86.4 and 82.5 vs. 61.7%), 1B (69.9 and 90.6 vs. 54.1%), 2 (60.5 and 63.3 vs. 16.5%), and 3A (39.9 and 47.4 vs. 23.1%). In multivariate analysis, the independent prognostic factors were age at operation, depth of tumor, duodenal food passage reconstruction, and lymph node metastasis. Our results indicate that both the extent of gastric resection and duodenal food passage reconstruction were important factors in the outcome of gastric cancer patients, and that surgeons should perform minimal gastric resection with preservation of the duodenal food passage when the gastric stump is tumor-free.

    ABSTRACT: The patient was a 61-year-old female who developed ileus. Physical findings showed abdominal distension but peritoneal irritation signs were not observed. After the conservative treatment by the ileus tube, encircling stenosis was observed in the jejunum at about 50 cm on the anal side from the Treitz ligament on contrast radiography of the small intestine through the ileus tube. Tumor markers were normal except for mild elevation of IL2-R (609 U/ml). After confirming sufficient bowel decompression and the absence of other lesions, surgery was performed based on a preoperative diagnosis of small intestinal tumor including adhesive ileus, GIST, or malignant lymphoma. First, under the laparoscopic observation, the lesion was resected and definitive diagnosis was established as primary moderately to poorly differentiated adenocarcinoma of the small intestine by rapid intraoperative pathological diagnosis. Then, extensive jejunal resection involving sufficient lymph node dissection was performed as open surgery. Radical surgery was successfully performed.

    ABSTRACT: A 44-year-old male presented to our hospital with abdominal pain. The upper endoscopy revealed advanced gastric cancer. On the abdominal CT, there was evidence of multiple, massive liver metastases. After total gastrectomy, the patient was treated with daily oral administration of 120 mg TS-1 for 4 weeks followed by 2 weeks' rest and 6 weekly infusions of 10 mg CDDP in an intra-hepatic artery as 1 cycle. On the follow-up CT, the liver metastases had decreased significantly both in size and number after 2 cycles. The current case suggests that TS-1 and CDDP may have a potent therapeutic efficacy in cases of advanced gastric cancer with multiple liver metastases.

    ABSTRACT: Tracheal agenesis is a rare congenital anomaly which results inevitably in immediate respiratory distress after delivery. Since the first report of the case in 1900, more than 150 cases reported in the Japanese and world literature. Attempts to save these children have failed to permit survival although a slight prolongation of life was achieved in some. We treated a baby girl with tracheal agenesis associated with other multiple anomalies and surgical intervention was attempted but without success due to incorrectable anatomy. Herein we describe her clinical picture and autopsy findings. Along with a review of the Japanese literature, we discuss this rare anomaly in terms of its anatomy, associated anomalies, pathogenesis, and clinical management.

    ABSTRACT: The purpose of this study is to determine whether a lymph node identified with high radioisotope (RI) activity is a sentinel node. We studied 26 patients with either esophageal or gastric cancer whose preoperative imaging studies showed no lymph node metastasis. Before surgery, Tc-99m tin colloid was injected via endoscopy into the submucosa. In lymph nodes dissected at surgery, RI activity was measured by a scintillation counter, and metastatic status was examined by hematoxylin-eosin staining. The number of dissected nodes was 45 +/- 15 (mean +/- SD) per patient, and the number of nodes with high RI activity was 4 +/- 1. Nodal metastasis occurred in 11 of 26 patients. In 9 of these 11 patients, metastatic foci were found in one or more nodes with high RI activity. In one of the 2 remaining patients, endoscopic clipping was applied just above the injection sites, and in the other patient, the tumor invasion was beyond the muscle layer. For further analysis, the case with clipping was excluded, and only those in which the tumor invasion was confined within the muscle layer were evaluated. Six of 18 patients in this analysis showed nodal metastasis. Each of the 6 patients had at least one node that showed high RI activity and that was positive for metastasis. We conclude that when tumor invasion remains within the muscle layer, lymph nodes with high RI activity can be regarded as sentinel nodes.

    ABSTRACT: There are no strategies to predict a patient's response to therapy. In a previous report, we classified Japanese patients into four groups according to the incidence of HLA antigens, by using quantification method III. In that study, we examined the patients' incidence of HLA antigens before surgery and evaluated their outcome according to the HLA classification by quantification method III. The aim of the present study is to evaluate whether HLA classification should be used in the treatment of individual cancer patients.A consecutive series of 76 Japanese patients who had undergone gastrectomy between July 1998 and January 2000 was evaluated to compare the patients HLA classifications, derived from quantification method III, with their prognoses following gastrectomy.Retrospective analysis of 193 gastric cancer patients revealed that HLA type I, type II, and type IV patients who had received postoperative adjuvant chemotherapy concomitant with PSK survived longer than those who had received postoperative adjuvant chemotherapy, whereas HLA type III patients who had received postoperative adjuvant chemotherapy showed significantly longer survival than those with chemotherapy+PSK. Following these results, we started a prospective study; we treated patients with HLA type I, type II, and type IV for postoperative chemotherapy+PSK, and those with HLA type III for postoperative chemotherapy following gastrectomy. The prospective study showed that patients who had been examined for HLA antigens showed significantly longer survival than those who had not been examined for HLA antigens.From the results of our retrospective and prospective studies, it can be inferred that it is necessary to examine gastric cancer patients for HLA antigens, and that HLA-oriented therapy is a very promising strategy for cancer treatment. We are planning to conduct an important study with control subjects.

    ABSTRACT: In a 55-year-old man, a tumor about 3 cm in diameter was detected in the upper abdomen by abdominal ultrasound screening during follow-up of chronic hepatitis C discovered in 1990. There were no symptoms and no abnormalities on physical examination. Tests for tumor markers were negative. By barium meal and gastroscopy, submucosal tumor was found on the lesser curvature of the stomach, with bridging fold in the absence of central ulceration. Biopsy revealed no tumor tissue. Under the diagnosis of submucosal tumor of the stomach, either a leiomyoma or leiomyosarcoma, partial resection of stomach was performed. Direct invasion of the surrounding organs, lymph node metastasis or distant metastasis was not observed grossly in the operation. Histologic examination of the resected specimen revealed proliferation of spindle cells and oval cells in an interlacing pattern. Immunohistochemistry for CD34, vimentin and c-kit protein was strongly positive, while smooth muscle actin, S-100 protein, desmin and p53 protein were negative. The proliferating cell nuclear antigen index was about 50%, while the MIB-1 index was < or = 1%. From these findings, this tumor was diagnosed as a gastrointestinal stromal tumor of the uncommitted type.

    ABSTRACT: To detect the effect of the loss of alimentation rhythmicity on a circadian rhythm of human growth hormone (HGH) secretion, a 24-hour profile of HGH was studied in a growing child on cyclic nocturnal total parenteral nutrition (TPN). Twenty-four-hour profiles of substrates and metabolic hormones were also studied to evaluate the efficiency of cyclic nocturnal TPN on childhood growth. Periodic blood samples from a child with megacystis-microcolon-intestinal-hypoperistalsis syndrome were obtained on five occasions, at ages 6, 7, 8, 9, and 11, when she was on cyclic nocturnal TPN. Peak HGH secretion appeared with the onset of deep sleep despite the concomitant hyperglycemia and hyperinsulinemia induced by TPN at night. Smaller peaks of HGH were also observed during the noninfusion period during the day. Twenty-four-hour profiles of substrates and metabolic hormones indicated a switch from glucose use during the infusion phase to an oxidation of lipids during the noninfusion period. The fact that the patient's growth curve remains within normal limits suggests that cyclic nocturnal TPN would be an efficient method of nutritional support. During cyclic nocturnal TPN, regular rhythm of HGH secretion occurs, and normal childhood growth is achieved.

    ABSTRACT: We encountered six cases of total parenteral nutrition (TPN)-associated lactic acidosis during the 6-y period of 1988-1993. The patients were characterized by severe disease of the digestive organs, minimal food intake before surgery, and postoperative TPN with no food intake and with no vitamin supplements. Within 4 wk of TPN, they developed hypotension (< or = 80/60 mmHg), Kussmaul's respiration, and clouding of consciousness, as well as abdominal pain not directly related to the underlying disease. Routine laboratory examinations revealed no acute aggravation in hepatic, renal, or pancreatic functions. Arterial blood gas analysis showed pH < or = 7.134 and base excess < or = -17.5 mmol/L. Additional laboratory examinations revealed serum lactate > or = 10.9 mmol/L, serum pyruvate > or = 159 mumol/L, and lactate/pyruvate ratio > or = 0.029. None of the patients responded to sodium bicarbonate or other conventional emergency treatments for shock and lactic acidosis. After the first case, we suspected that thiamine deficiency might be responsible for this pathologic condition, Serum thiamine was proved to be < or = 196 nmol/L in 5 patients. Thiamine replenishment at intravenous doses of 100 mg every 12 h resolved lactic acidosis and improved the clinical condition in 3 patients. This article includes a review of 11 relevant reports published from 1982-1992 and a discussion of the biochemical mechanism of onset of thiamine deficiency-associated lactic acidosis. We emphasize the needs (1) to supplement TPN with thiamine-containing vitamins for the patients whose food intake does not meet nutritional requirements; (2) to monitor the patients routinely measuring serum thiamine concentration and erythrocyte transketolase activity during TPN; and (3) to intravenously replenish using high-dose thiamine simultaneously with the manifestation of signs and symptoms of lactic acidosis.

    ABSTRACT: Shoshin beriberi is a state of cardiovascular collapse due to metabolic acidosis caused by vitamin B1 (thiamine) deficiency. A 36-year-old female was admitted to the hospital because of disturbance of consciousness and edema in the lower extremities and face. She had taken only precooked foods for long periods. Hemodynamic abnormalities with a high cardiac output (5.871/min/m2) and high CVP (18 cmH2O) were observed in a state of severe metabolic acidosis (pH 6.87, BE-21.4mEq/l). Chest X-ray film demonstrated slightly enlarged cardiac size. CT and ultrasound studies revealed the dilated inferior vena cava and enlarged spleen and liver. In cardiac ultrasound test, pericardial effusion was noticed. The circulatory failure and metabolic acidosis were resistant to the intensive therapy with catecholamines, sodium bicarbonate and various fluid transfusions. After administration of thiamine (200 mg IV every day for 4 days), the abnormalities of hemodynamics and acid base balance returned to normal range. Consciousness state also recovered to normal condition in 5 hours after thiamine therapy. In conclusion shoshin beriberi should be considered in patients with malnutrition or alcoholic who develop cardiac failure or metabolic acidosis of unexplained etiology.

    ABSTRACT: Three-dimensional images of the pelvic structure of patients with anorectal malformation (ARM) were constructed by computer graphics based on radiographic computerized tomography (CT) and magnetic resonance (MR) images. Organ contour data from CT images and raw MR image data were transferred to a personal computer and to a graphic workstation respectively. On MR image processing, organs were extracted semiautomatically by thresholding enclosed areas. After several steps of image processing, three-dimensional anatomy of each anomaly was visualized with emphasis on position and shape of the muscle complex. In control patients without an anomaly, images showed that the rectum is supported by the levator muscle from behind and descends along with the urethra. In the male patient, the anal canal separates from the urethra and penetrates through the middle of the sphincter complex to reach the orifice. In those with low-type anomaly with a fistula opening to the perineum or the vestibule, images showed the fistula descending through the anterior portion of the sphincter complex. Images of those with a rectourethral fistula could show the muscle complex behind the rectum and at the region where the external sphincter should be. In those with cloacal anomalies, anatomical position and the shape of three different viscera were easily recognized, and the muscle complex was shown like that of rectourethral-type anomalies. This study is a new approach to the anomaly to facilitate understanding it and can assist a surgeon in planning a procedure. This kind of application would make it possible for a surgeon to consider the strategy on a display screen before the real surgery.

    ABSTRACT: A 19-month-old girl who had a history of constipation since birth and suspected cytomegalovirus (CMV) infection was admitted. Barium enema revealed no caliber change in the colon, anorectal manometry failed to show sphincter relaxation on rectal distension, and biopsied rectal specimens contained ganglion cells. She underwent rectal myectomy, after which her symptoms improved significantly. Morphologic studies, including electron micrographs of the muscle, demonstrated nerve plexuses with degenerative Schwann cells containing abundant eosinphilic cytoplasmic granules that resembled those of a granular-cell tumor. Granular-cell tumorlike change of the plexus is an unprecedented finding in any form of Hirschsprung's disease or its allied disorders, but appears to have been responsible for her symptoms. CMV as a causative agent is also discussed with a review of the literature.

    ABSTRACT: The current role of surgery was evaluated in seven consecutive patients with high-risk neuroblastoma (six stage 4 patients and one stage 3, abdominal origin, and all over 12 months of age at diagnosis) treated with new modalities utilizing bone marrow transplantation (BMT). In six of these seven patients, a grossly complete excision of the primary tumor was achieved, and four have survived for 133, 69, 39, and 28 months with no further evidence of disease. The remaining patient with celiac neuroblastoma only underwent a biopsy during a second-look laparotomy after chemoradiotherapy, and thereafter developed local and distant recurrences and ultimately succumbed to the tumor. The timing of surgical intervention varied, either before or after chemotherapy, and did not appear to affect the ultimate survival. Although surgical excision of the primary tumor remains a very high priority in the overall treatment scheme, the most important factor remains the eradication of the tumor by well-planned courses of intensive chemotherapy (e.g., A1 Protocol of the Study Group of Japan). Thus, after having induced complete remission, for consolidation, it is necessary to kill all remaining tumor cells by giving supralethal doses of chemotherapy including total body irradiation (TBI) assisted by BMT.
