Laparoscopy-assisted distal gastrectomy (LADG) has been advocated as a minimally invasive operation for early gastric cancer which needs regional lymph node resection. However, since it is technically too complicated and difficult to perform all laparoscopic procedures within the abdominal cavity, LADG has not become the standard surgical procedure for early gastric cancer. Moreover, a skin incision of approximately 5cm is required to allow the reconstruction of the digestive tract after gastrectomy. Therefore, we have developed an operative procedure which we call hand-assisted laparoscopic distal gastrectomy (HALDG). In this procedure we make a skin incision of 6cm, and the surgeon inserts his/her left hand into the abdomen to assist the laparoscopic procedure. The surgeon can move his/her left hand freely, to palpate and explore the organs, as in an open surgery. Therefore, the operation time can be shortened. Our results thus far obtained demonstrated that HALDG was as safe and effective as open distal gastrectomy. HALDG assures the patients a better quality of life, --less surgical trauma, less pain, speedy return to dialy life activities. Thus, it is beneficial to the patients with early gastric cancer. We, therefore, advocate the use of HALDG in such cases.

BACKGROUND : This survey examined how a physician's specialty may influence attitudes towards blood glucose control in diabetic patients.
METHODS : A questionnaire was mailed to all members of the Ishikawa Medical Association (n=1,610) as well as diabetic specialists (n=36) querying their specialties, confidence in offering diabetic treatment, and treatment goals/change levels of plasma glucose levels for 5 theoretical cases.
RESULTS : 301 physicians responded. The percentage answering treatment goal/change levels was 93% of internal medicine physicians (n=145), 72% of surgeons (n=29), 52% of pediatricians (n=23) and 20% in other specialties (n=99). The percentage answering “I am confident in offering diabetic treatment” was 57% of internal medicine physicians, 14% of surgeons, 13% of pediatricians and 3% in other specialties. There were significant differences among specialties in the fasting plasma glucose levels in the treatment goal, and the postprandial plasma glucose change levels. Internal medicine specialists tended to give higher glucose levels than other specialties.
CONCLUSIONS : The majority of physicians interested in diabetes care appear to be internal medicine specialists. Physician's specialty may influence their attitude toward glucose control in diabetic patients.

A 65-year-old woman was referred for progressive dyspnea and leg edema. Physical examination revealed a continuous murmur along the right sternal border. Enhanced computed tomography showed an aneurysm that extended to the right atrium. Aortic angiography confirmed the rupture of the valsalva aneurysm into the right atrium. The patient underwent emergency surgery to close the aneurysm ostium and suture closure of the right atrial fistula. The patient's postoperative course was uneventful.

Aim:The usefulness of high-density barium, which was made to 150w/v% (MIX150), was examined to obtain better radiographs of the intestines. Methods: “MIX150” was compared with existing pharmaceutical “BAM100” to evaluate x-ray images (barium adhesion, dryness evaluation). MIX150 was used in 232 patients (mean age 56 years), while BAM 100 in 210 patients (mean age 55 years). Results: In terms of adhesion, MIX150 was excellent in the the cecum significantly and in dryness evaluation, in the entire region of the colon. Conclusion: High-density barium (150w/v%) was useful for enhancing the quality of radiographic images.

The results of pulmonary function tests (PFTs) given to those inhabitants in the western part of Kanagawa Prefecture who visited our hospital for medical examinations between April 1991 and March 1992 were studied comparatively, with their occupation, age, sex, environmental factors and smoking habits taken into account. For this purpose, the subjects totaling 1, 322 were classified into three groups-those who live in the hilly area, those who live in the suburban area and those who live in the coastal area. In the present study, the results of the four PFT items-FVC, FEV 1.0%, FVC and FEV 1.0%-were checked. Careful examination brought into relief the startling fact that many aged people, non-farmers and nonsmokers in the suburban subject group have impaired pulmonary function. It is said that because of the Tokyo-Nagoya expressway and many other motorways, the air in the suburban area is fouled up with exhaust gas to a greater extent than in the other two areas. Although our finding alone could not identify the cause of impaired pulmonary function definitely, air pollution was thought to be a culprit. Further investigation should be made into the living conditions of the examinees. Moreover, environmental monitoring and data analysis have to be carried out in the future.

Before the introduction of high density barium for contrast studies of the upper gastrointestinal tract, we conducted a survey concerning the adverse reactions to a swallow of barium and barium concentration.
The incidence of side effects rose as the density of barium increased but the effects were transient. There were no cases requiring medical treatment.
Furthermore, the constipation group and the normal group were examined separately.
The ratio of adverse reactions was high in the constipation group even when the barium density was low. In this group stool hardening and delayed excertion were also noticed.
The constancy of barium stool excretion was basically normal, and the barium density had little effect.
The effects of a laxative on the excretion consistency were investigated. The administration of a laxative did not always have a positive affect on excretion. The timing of the administration of the laxative and the amount of water intake should be examined in the future.
We also investigated how the patients feel when they are swallowing barium. We found that whether feel uncomfortable or not depended on the properties of barium rather than its density.
From these results it appears that appropriate guidance is necessary about the use of high density barium, in order to supress the occurrence of side effects, especially in the constipation group.

STUDY DESIGN: Retrospective review. PURPOSE: To describe a safe and effective surgical procedure for old distractive flexion (DF) injuries of the subaxial cervical spine. OVERVIEW OF LITERATURE: Surgical treatment is required in old cases when a progression of the kyphotic deformity and/or persistent neck pain and/or the appearance of new neurological symptoms are observed. Since surgical treatment is more complicated and dangerous in old cases than in acute distractive-flexion cases, the indications for surgery and the selection of the surgical procedure must be carefully conducted. METHODS: To identify a safe and effective surgical procedure, the procedure selected, reason(s) for its selection, and associated neurological complications were investigated in 13 patients with old cervical DF injuries. RESULTS: No neurological complications were observed in nine patients (DF stage 2 or 3) who underwent the anterior-posterior-anterior (A-P-A) method and two patients (DF stage 1) who underwent the posterior method. It was initially planned that two patients (DF stage 2) who underwent the P-A method would be treated using the Posterior method alone; however, anterior discectomy was added to the procedure after the development of a severe spinal cord disorder. CONCLUSIONS: The A-P-A method (anterior discectomy, posterior release and/or partial facetectomy, reduction and instrumentation, anterior bone grafting) is considered to be a suitable surgical procedure for old cervical DF injuries.

Data from the first trial of the computer-based nationwide common achievement test in medicine, carried out from February through July in 2002, were analyzed to evaluate the applicability of the item-response theory. The trial test was designed to cover 6 areas of the core curriculum and included a total of 2791 items. For each area, 3 to 40 items were chosen randomly and administered to 5693 students in the fourth to sixth years; the responses of 5676 of these students were analyzed with specifically designed computer systems. Each student was presented with 100 items. The itemresponse patterns were analyzed with a 3-parameter logistic model (item discrimination, item difficulty, and guessing parameter). The main findings were: 1) Item difficulty and the percentage of correct answers were strongly correlated (r=-0.969to-0.982). 2) Item discrimination and the point-biserial correlation were moderately strongly correlated (r=0.304 to 0.511). 3) The estimated abilities and the percentage of correct answers were strongly correlated (r=0.810 to 0.945). 4) The mean ability increased with school year. 5) The correlation coefficients among the 6 curriculum area ability scores were less than 0.6. Because the nationwide common achievement test was designed to randomly present items to each student, the item-response theory can be used to adjust the differences among test sets. The first trial test was designed without considering the item-response theory, but the second trial test was administered with a design better suited for comparison. Results of an analysis of the second trial will be reported soon.

STUDY DESIGN: Retrospective case series. PURPOSE: To clarify the influence of cervical spinal canal stenosis (CSCS) on neurological functional recovery after traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation. OVERVIEW OF LITERATURE: The biomechanical etiology of traumatic CSCI remains under discussion and its relationship with CSCS is one of the most controversial issues in the clinical management of traumatic CSCI. METHODS: To obtain a relatively uniform background, patients non-surgically treated for an acute C3-4 level CSCI without major fracture or dislocation were selected. We analyzed 58 subjects with traumatic CSCI using T2-weighted mid-sagittal magnetic resonance imaging. The sagittal diameter of the cerebrospinal fluid (CSF) column, degree of canal stenosis, and neurologic outcomes in motor function, including improvement rate, were assessed. RESULTS: There were no significant relationships between sagittal diameter of the CSF column at the C3-4 segment and their American Spinal Injury Association motor scores at both admission and discharge. Moreover, no significant relationships were observed between the sagittal diameter of the CSF column at the C3-4 segment and their neurological recovery during the following period. CONCLUSIONS: No relationships between pre-existing CSCS and neurological outcomes were evident after traumatic CSCI. These results suggest that decompression surgery might not be recommended for traumatic CSCI without major fracture or dislocation despite pre-existing CSCS.
