JOURNAL FREE ACCESSCardiovascular complication often occur during gastroendoscopy. Sudden cardiac arrests, myocardial infarctions and myocardial ischemias have all been reported during gastroscopy. Thus, comparisons were made of electrocardiograms (ECG) and vectorcardiograms (VCG) of elderly patients before, during and after gastroscopy. And blood pressure were monitored during gastroscopy of elderly patient. A standard 12 lead-electrocardiogram was taken on 35 aged patients (more than 60 years of age) and 10 control subjects (less than 59 years of age): (a) before gastroendoscopy, (b) after prifinium bromide intramuscular injection (30mg) and Xylocaine viscous anesthesia, and (c) during gastroendoscopy (GTF-S3 and GTF-B2). Maximum QRS vector, maximum T vector, QRS-T angle and QRS-T retio were recorded on vectorcardiograms in 19 other aged patients: (a) before gastroendoscopy, (b) during endoscopy and (c) after endoscopy. The heart rate increased in all 35 patients and 10 control subjects during gastroendoscopy. Twenty patients (57%) and 4 control subjects (40%) showed increases to more than 100 beats per minute. One aged patient a supraventricular premature beat, and another patient had a ventricular premature beat. Thirteen of these patients (37%) showed ST-T changes. One of them showed an ST-elevation and 12 showed ST-depressions. Maximum QRS vector and maximum T vector decreased in most aged patients. Most patients showed a tendency for an increase in the QRS-Tretio. Nine of 19 patients (47%) showed ischemic changes. The present study confirmed that many ischemic changes occur in elderly patients. Therefore, a precautionary cardiovascular examination is recommended of elderly patients prior to gastroendoscopy.View full abstractDownload PDF (10092K) -

JOURNAL FREE ACCESS17 cases (including 7 probable cases) of colonic tuberculosis (tbc) were studied in reference to clinical findings, the method of the definite diagnosis and X-ray features. Only 2 cases had active pulmonary tbc. Mantoux tests were all positive but one case, which had no ulceration. Erythrocyte sedimentation rate was accelerated on all cases with ulceration. 12 out of 17 cases had various stages of ulcer, and tubercle bacilli were detected by cultivation of biopsy specimen in 9 out of 12 ulcerated cases. One of 3 cases in which tubercle bacilli could not be detected was definitely diagnosed by the investigation of the resected material, the other 2 were treated with anti-tuberculous drugs before the culture. We could get high positive rate, 9 out of 10 (90%), on cultivation in cases without therapy. Biopsy specimen were taken from the bottom or edge of the ulcer and there was no relation between results of tubercle bacillus culture and shape, size or depth of ulcers. On the other hand, the histological examination by biopsy revealed granuloma only in one case, but caseous necrosis did not exist. It will be considered that tubercle bacilli always exist on the bottom of active ulcers and that tubercle bacillus culture will be more effective than the histological exmination for the definite diagnosis of the cononic tbc. Out of 10 definite cases, there were 3 cases which had not so-called "scarred area with discoloration." The author classified X-ray patterns of colonic the into 3 groups.View full abstractDownload PDF (6853K) -

JOURNAL FREE ACCESSEndoscopic classification of esophageal varices proposed by Japanese Portal Surgery Meeting was applied to 170 cases with portal hypertension for the purpose of determining which signs are useful in predicting variceal bleeding. The summarized conclusions are as follows: (1) Among 54 actively bleeding sources, esophago-gastric varices (48.1%) and hemorrha-gic gastritis (33.3%) were the most frequent. (2) Variceal bleeding was observed in 38% of stage 3 cases. Especially, in stage 3 cases with hematocystic spot, variceal bleeding was most frequently seen (78.5%). Thus, the hematocystic spot was thought to be the most important endoscopic sign to foresee the variceal bleeding. (3) As the result of endoscopic observations of varices for more than a year, an endoscopic examination should be performed once a year in stage 1 and once every 6 months in stage 2. (4) Follow-up study of esophageal varices suggested the necessity for prophylactic operation on varices not only in stage 3, but also on combined nodular and blue varices.View full abstractDownload PDF (3964K) -

JOURNAL FREE ACCESSA patient with Mallory-Weiss syndrome, 20-year-old male, presented with a chief complaint of hematemesis after alcohol ingestion followed by vomiting. An endoscopic examination revealed a mucosal tear on the posterior wall of the gastric cardia. A patient with Boerhaave's syndrome, 57-year-old male was hospitalized because of chest pain immediately after vomiting. A chest x-ray showed left pneumothorax and pleural effusion. Endoscopic and gastrograf in swallow studies demonstrated an esophageal ruputure on the left wall just above the esophagogastric junction. Emergent surgery with a diagnosis of spontaneous esophageal rupture was performed but the patient died of sepsis and G. I. bleeding. A patient with acute longitudinal linear ulcer of the stomach, 77-year-old male who was treated with reserpine for hypertension and analgegic for lumbago, entered the hospital because of tarry stools. He did not drink alcohol and denied any causes increasing abdom-inal pressure. Endoscopic examination revealed a longitudinal linear ulcer on the posterior wall of the gastric cardia. It seems to be important for making a diagnosis in such cases to take a detailed history and emergent endoscopic examination is imperative.View full abstractDownload PDF (4779K) -

JOURNAL FREE ACCESSUpper gastrointestinal emergent endoscopy was performed in 100 patients for the recent two years. All cases were examined with a panview type gastrointestinal endoscopy within 48 hours after hematemesis or melena appeared. The sources of upper gastrointestinal bleeding in these 100 cases were as follows; gastric ulcer (44), duodenal ulcer (19), esophago-gastric varices (11), Mallory-Weiss syndrome (11), stomal ulcer (2), hemorrhagic gastritis (2), esophagitis(2), gastric cancer(1), gastric polyp(1), hemoptysis(1), nasal bleeding(1), and unknown cases (5). Hemostasis was performed in 67 cases by conservative therapy and surgical operation was performed in 33 cases. Essential treatment was not performed in 4 died cases because of poor general conditions. After checking blood plessure, hematocrit value and ECG, this examination was performed during drip infusion to be safety of circular system. No complications were encountered. To confirm the source of bleeding at earlier stage, was useful to decide which way, that is conservative or surgical therapy in much better for the management.View full abstractDownload PDF (2852K) -

JOURNAL FREE ACCESSTiny white spots were found in the surrounding mucosa of 7 out of 21 removed polyps via colonoscope, all of which were histologically malignant. These white spots were best observed under colonoscopy and revealed histologically a collection of foamy cells just below the surface epithelium between tubules with faintly stained granules by H & E stain-ing. They were also seen in the adjacent mucosa of frank carcinomas and histological study of 100 consecutive colorectal carcinomas showed these foamy cells in 32 percent. Histochemically they were positive by PAS, alcian blue, mucicarmine and toluidine blue but negative by oil red O, showing most similar property of ′muciphages′ described by Azzopardi et al. In the surrounding mucosa of a large pedunculated adenoma and several adenomas in adenomatosis coli these white spots were also noticed. However, the presence of white spots seems to be a usefule marker for the colonoscopic diagnosis of focal and invasive carcinoma, although they were exceptionally found in other conditions such as ulcerative colitis and benign adenomas. The nature of these white spote were discussed and clinical usefulness of this findings was stressed.View full abstractDownload PDF (5316K) -

JOURNAL FREE ACCESSDye spraying method has been used jointly with routine rectosigmoidscopy in 217 cases complaining of diarrhea or lower abdominal discomforts. Age distribution of the above patients ranged from 17 to 78, and 46.6 in the average. After finishing the ordinary endoscopic observation of the rectum, 0.13% solution of indigocarmine was sprayed on the rectal mucosa under the direct vision. Sixty four minute polypoid lesions among 217 cases (29.5%) which were too small to be found out by ordinary endoscopic examination were detected through the contrast effect of the dye. Biopsy specimens revealed histologically tubular adenoma with mild atypia in 9, metaplastic polyp in 15 and solely rectal mucosa in 39 cases. In one particular case, scattering small polypoid lesions showed adenocarcinoma, which was confirmed later in autopsy to be a case with rectal metastasis from gastric cancer. It may be said that a dye-spraying method used jointly with rectosigmoidoscopic examination is useful not to overlook the small polypoid lesions.View full abstractDownload PDF (4970K) -

JOURNAL FREE ACCESSLaparoscopic examinations were performed in 30 patients with pancreatic cancer and 7 patients with chronic pancreatitis. As to the method of pancreatic observation, a supragastric method was chosen in the cases of pancreatic cancer in the body and / or tail and chronic pancreatitis. The results obtained as were follows: 1) In all 16 cases except one with pancreatic cancer in the head, the greenish liver accompanied by enlarged gallbladder was observed. In such cases of obvious obstructive cholestasis, endoscopic detection of intraperitoneal metastasis was mainly conducted, instead of unnecessary observation of pancreas itself. 2) Observation of the pancreas was succeeded in 10 out of 11 cases with pancreatic cancer in the body and / or taro (91%), and in 4 out of 7 cases with chronic pancreatitis (57%). Three cases were not tried to observe pancreas, because the liver metastasis was obvious. 3) In both chronic pancreatitis and pancreatic cancer which had not invaded the pancreas capsule yet, the pancreas appeared increasing in its white color tone and in its consistency. 4) In pancreatic cancer which had already invaded the capsule, findings of vascular stenosis and cut off of fine vessels on the pancreatic surface were observed. In pancreatic cancer which had not invaded the capsule yet, however, endoscopic differenti-ation from chronic pancreatitis seemed almost impossible. 5) An aspiretion biopsy of the pancreas by a fine needle was proved as very useful procedure for the differential diagnosis between pancreatic cancer and chronic pancreatitis.View full abstractDownload PDF (7561K) -

JOURNAL FREE ACCESSAssessments of the diagnostic value of 4 tests in 22 patients with a proven carcinoma of the pancreas were made. ERCP, US, CT and RI were interpreted as correct, suspicious and incorrect according to the criteria described previously by us and others. ERCP and CT were most sensitive in diagnosing pancreatic cancer (77.3%, 72.2%, respectively). These 4 tests offered complementary, correct or suspicious information in the evaluation of pancreatic cancer. An indirect sign on US and CT in patients with jaundice is dilatation of the intrahepatic biliary tree. All the 4 tests are useful for the diagnosis in patients with or without jaundice. Most of tumors are not found at a resectable stage. In this series only 4 patients had a resectable pancreatic cancer. ERCP gave the correct diagnosis in these 4 patients. ERCP is the best means of detecting a resectable tumor. Most patients, however, ex-perienced vague, nonspecific symptoms at an early stage in the disease process. If an effec-tive diagnostic procedure were used at an earlier stage, not only, would the prognosis after resection be improved, but also a further group of patients who would otherwise progress to non-resectable disease could be identified and offered radical surgical treatment. We proposed a decision tree for the diagnosis of pancreatic cancer. A more sensitive diagnostic modality for the correct diagnosis of pancreatic cancer remains to be established. CT combined with angiography, RI with subtraction and direct magnification during ERCP are under investigation.View full abstractDownload PDF (10094K) -

JOURNAL FREE ACCESSClinical and pathophysiological features of 29 aged patients with duodenal ulcer were studied in comparison with young patients. Clinical and pathophysiological manifestions of aged duodenal ulcer patients were as follows; (1) Concerning the chief complaints, nearly half of the patients did not complain epigastric a / o back pain, but gastrointestinal bleeding (hematemesis, melena) and the symp-toms of functional pyloric stenosis after food intake were frequently noted. (2) In aged duodenal ulcer patients, a recurrent history was more common and the ulcer healing tended to delay compared to young patients. (3) Gastric acid secretion (BAO, MAO) maintained relatively at a high level and endoscopic congo-red patterns indicated a closed type, mainly type C1 or C2, compared to age-matched normal controls or gastric ulcer patients. (4) Gastric emptying was considerably rapid in all duodenal ulcer patients, tended to be more rapid with age and highly correlated with the recurrent history. (5) There was no significant tendency on the fasting plasma gastrin levels and integrated gastrin response to test meal.View full abstractDownload PDF (1022K) -

JOURNAL FREE ACCESSEndoscopy of the total colon has made much progress after repeated improvements of the colonoscope and technique of insertion, however, there still remain some difficulties. In our department, colonoscopy is performed without fluoroscopic controle in all cases. How-ever, at the sigmoid-descending junction or other strongly bending portion, it sometimes takes time in finding the bowel lumen. Furtheremore, the lesions behind the semilunal folds or just inner side of strongly bending portions may be overlooked occasionally. To resolve these difficulties, the authors emphasized the usefulness of the colonoscope with a wider view field since the beginning of its development. Now, for practical use, the authours have made a trial model colonoscope with a wider view field in cooperations with Olympus Optical Co.. Clinical significance of such wider view field has been studied, the results of which are stated below. Advantages of the colonoscope with a wider view field: (1) The bowel lumen can be found more easily, which makes it easy to introduce the instrument into the proximal colon. (2) A wider area of lesions including stenosis can be easily observed. (3) It is superior in observation of such areas as behind the semilunar folds or just inner side of strongly bending portions, which tend to be blind area. Disadvantage with a wider view field : (1) Distortion of the image is much larger than that of the conventional one.But in practical use, there seems to be little problem as to the distortion of the image with the examiner becoming experienced in using the wide angle lens. In conclusion, a colonoscope with a wider view field seems to have more advantages as a whole in comparison with the conventional instrument.View full abstractDownload PDF (8349K) -

JOURNAL FREE ACCESS44 patients of malignant lymphomas who were hospitalized for last ten years were stud-ied about their gastrointestinal lesions. We divided these cases into two groups, Hodgkin's disease (9 cases) and non Hodgkin's lymphoma (35 cases). Gastrointestinal infiltrating lesions of malignant lymphomas were found in one case of the former and ten cases of the latter. We found 6 infiltrating lesions in the stomach and small intestine, respectively and 3 lesions in the colon. We had observed an interesting gastric involvement endoscopically for three years. This case was forty-nine years old man and diagnosed lymphosarcoma, stage 4b. Gastric lesion was IIc like appearance with converging folds at the greater curvature of the gastric body. This lesion was considered the early state as the gastric involvement. Thereafter submucosal tumors and ulcerative lesions apperased at the posterior wall of the gastric body for three 'years. Finally this case was operated and the infitration of lymphosarcoma was proved. Furthermore we studied other benign gastrointestinal lesions of malignant lymphomas. Ten cases of ulceration and eight cases of massive GI bleeding due to the erosion were observed. One of ulcerations was perforated. The prognosis of patient have great relation with gastrointestinal lesions, which are not only infitrating, but also other benign lesions. Therefore we should diagnose them promptly and treat properly.View full abstractDownload PDF (5091K) -

In this paper, we present two successful cases of endoscopic extraction of misdrunk needle in children. One is a 1-years-old boy, and the other is a 2-yeprs-old girl. Under GOF anesthesia, endoscopy was applied by using a small size panendoscope (GIF-P2, Olympus), and the needle was found sticking into the gastric or duodenal mucosa. Using a snare catheter inserted through the f iberscope, the needle was successfully extracted under direct vision with no hazards. In addition, the usef ullness of upper GI endoscopy to pediatric patients is discussed in this paper.View full abstractDownload PDF (5637K) -

JOURNAL FREE ACCESSCancer of the residual stomach have been generally divided into two groups, depending upon the initial operation whether it is for benign disease or gastric cancer. This time, we have experienced 8 cases of cancer of the residual stomach, which devel-oped ten or more years after partinal gastrectomy. The diagnosis of these patients at the primary restction, were as follows:. 3 cases were gastric ulcer, one case was duodenal ulcer, 3 cases were early gastric cancer, and one case was advanced gastric cancer. Macroscopically, they were recognized as Borrmann type 111 in 6 cases, and as Borrmann type N in 2 cases. Pathologically, all cases were adenocar-cinoma.It is reaffirmed that endoscopy is useful on diagosis for cancer of the residual stomach. The selection of instrument might be necessary in individual cases.View full abstractDownload PDF (4060K) -

JOURNAL FREE ACCESSA 34-year-old male was admitted to our hospital complaining of epigastric pain and loss of weight. A barium examination revealed poor distensibility of the entire stomach and mural rigidity: no ulcer crater could be identified. Endoscopic examination showed a rough-granular protruded lesions of the stomach. Scirrhous carcinoma of the stomach was suspected, however malignant cell was negative in several gastric biopsy materials. Gross finding of resected stomach was smooth and showed no evidence of ulceration. Histologically a great number of epethelioid cell tubercles mixed with Langhans' giant cells were seen in the muscularis propria. Although special stains failed to reveal the presence of tubercle bacilli, the diagnosis of tuberculosis of the stomach was made based upon patholo-gical findings.View full abstractDownload PDF (4690K) -

JOURNAL FREE ACCESSIt has been possible to find so many cases of prolapsing gastric polyps and polypoid early gastric cancers reported in Japan so far and prolapse of a polyp from the antrum is not an unusual occurrence on routine X-ray examination. On the other hand, a submucosal tumor of the stomach prolapsed or intussuscepted into the duodenum has been thought to be extremely rare. To the best of our knowledge, 25 cases of prolapsing submucosal tumors have been reported in Japan including 1 personal case (Table 2). In about half of the collected cases the lead tumors originated from upper areas of the stomach, and most cases were old age. This paper presented such a case, and a review was made on the literatures with reference to the clinical aspects, and discussed about the mechanism why nonpeduncu-lated large tumors located in the upper areas of the stomach were capable of prolapsing through the pylorus. The patient, a 74 year-old female, was admitted with complaints of continuous epiga-stric pain accompanied by nausea and postprandial vomiting. Physical examination on admis-sion revealed a tender mass in the epigastrium which was oval in shape and newborn hand in size. Upper GI series and endoscopic examinations revealed a submucosal tumor origin-ating in the body of the stomach intussuscepted into the duodenum with part of the gastric wall (Figure 1-4). Operative specimen (Figure 5) showed a smooth-surfaced oval tumor, 8 x 5.5 x 5.5 cm in size, and weighing 130 g. The tumor was elastic, soft and the mucous membrane was loosely attached to the tumor. Microscopical examination showed the tumor to be a schwannoma (Figure 6).View full abstractDownload PDF (6423K) -

JOURNAL FREE ACCESSA 56-year-old man with hepatoma, who had been treated with total 3, 960 rad of 60Co-irradiation 2 months previously, was readmitted to the hospital because of fever and anemia. Following admission, he passed tarry stools every day. Barium meal examination revealed esophageal varices and erosive gastritis of the antrum. At endoscopy, many hemor-rhagic erosions were found in the gastric antrum and the first part of duodenum, which were located in the irradiation area. Since repeated blood transfusion failed to improve anemia, a complete fasting with intravenous hyperalimentation and antacid therapy were started. Two months later, feeding was started and thereafter continued without any appre-ciable GI bleeding or worsening of anemia. Endoscopic examination at this time revealed only a few erosions scattered over the edematous antral mucosa as well as the proximal duodenum. IVH, antacids and abstinence from food seem to be an effective measure in the treatment of radiation injury of the gut.View full abstractDownload PDF (2871K) -

JOURNAL FREE ACCESSStomach cancer that shows healing and recurrence of the malignant ulcer repeatedly is called malignant cycle. Malignant cycle is often difficult to differentiate from benign one endoscopically. This is a case which showed recurrence of malignant cycle for three times during three years of endoscopic observation. The patient was 42 years old when he com-plained epigastric pain and was found a small round ulcer at the gastric angle by endoscopic examination for the first time. The ulcer seemed non-malignant endoscopically and healed at the end of the 2nd month. At the 4th month, the ulcer recurred and several regenerative epithelial foci were observed in shallow ulcer. At the 8th month, the ulcer healed at a red scar. At the 20th month, the ulcer recurred apparently, but healed to be a linear scar two months later. At the 30th month, the ulcer relapsed with some irregular margin. At the 36th month, the ulcer enlarged with manifest appearance of malignant cancer. Endoscopic biopsy was carried out at the first, 2nd, and 3rd recurrence, but was positive only at the last one. The ulcer might be a mucosal cancer from the beginning. The problem was a negative biopsy either by the covering benign regenerative tissue or the failure of aiming.View full abstractDownload PDF (11251K) -

JOURNAL FREE ACCESSBetween 1972 and 1979, 2, 076 ERCP examinations have been performed using conven-tional fiberduodenoscope with visual angle of 64°. Cannulation into the orifice of the papilla of Vater was successful in 1, 990 (95%). A success rate for cannulation of the pancreatic duct was 92% and successful cannulation of the common bile duct was achieved in 81%. A new wide-viewing fiberduodenoscope was recently developed. The Fujinon FD-QB has a visual angle of 105°, working length of 1, 340 mm, the tip deflection of 120° and focal depth of 2-80 mm. Advantages of using this scope for ERCP are as follows: (1) the papilla of Vater is easily searched due to the wide viewing angle; (2) ideal position for the cannu-lation into the common bile duct is obtained due to the wide viewing angle and soft deflec-table section; (3) examination time can be mitigated. Using this scope 374 ERCP examina-tions have been performed. An overall success rate for cannulation was 98%. Selection of the desired duct was significantly improved. A success rate for cannulation of the pan-creatic duct, bile duct and both the pancreatic and bile ducts was 96%, 87% and 90% res-pectively.View full abstractDownload PDF (4391K)
