Statistical Observation of Ileocecal Intussuception

This report includes experiences of 63 cases of lntussusception treated in Severance Hospital from October 1964 to September 1968. 1. In age distribution, 44 cases were observed under one year of age (69.9%) and peak incidence occurs from the 4th to 7th month (38%). Males showed a decidedly higher incidence than females with a ratio of 2.3:1. Seasonal incidence showed 33.3 per cent in the Summer. 2. The cardinal symptoms and signs were irritability or abdominal pain, palpable abdominal mass, vomiting, and bloody mucous stools. 3. 7 out of 63 cases had an underlying cause; Meckel's diverticulum 2, enteric cyst 1, submucosal cyst 1, lymphosarcoma 1, reticulum cell sarcoma 1, and malrotation, and 5 cases out of six were under 3 years of age. 4. Of 63 cases, operative intervention without trial of barium enema reduction was used in 24 cases, 7 cases had only diagnostic barium enema. In the rest of the cases, namely 32 cases, hydrostatic pressure barium enema was performed and successful reduction was accomplished in 13 cases.

Experimental Study on Fat Absorption (I131-Triolein) from the Parasite Infected Intestine

The effects of Clonorchis sinensis, Hymenolepis nana and Toxocara canis infection on fat absorption in the intestine were studied. For this purpose, I131-Triolein was given to the animals which were infected by those parasites, and amounts of the excretion in the feces were counted and following results were obtained. In the Clonorchis sinensis infected group, the excretion of Triolein was increased to 4. 10~4.49% compared with that of the control group. In the Hymenolepis nana infected group, the excretion of Triolein was increased to 4~5% compared with that of control group. In the Toxocara canis infected group, the excretion was about twice as much as that of the control group. It is concluded that parasite infection in digestive system diminishes fat absorption in gastrointestinal tract of the host.

Observation of Primary Carcinoma of the Lung

Analysis of our primary bronchogenic carcinoma is restricted to 65 cases that have been regarded as having satisfactory histological and cytological proof of diagnosis by bronchial washing and bronchos opic biopsy and they were primarily diagnosed by roentgenography. Of these 65 cases, 59 cases were diagnosed by bronchoscopic biopsy and 6 cases were proved by bronchial washing. In the sex incidence, there were 49 males and 16 females, The peak incidence of bronchogenic carcinoma was 41.5 per cent in the fifth decade, 30.8 per cent in the fourth decade, and 1.5 per cent in the second decade. Cough, sputum raising, chest pain, and dyspnea were the most common complaints but three patiens had no signs or symptoms. The pathological classification, metastasis and complication were discussed for these 59 cases. Radiological classification of lung cancer revealed the following types: central pneumonic form; central solid form; central infiltrating form; peripheral solid form; peripheral cavitary form. 86.2% was central hilar type and 13.8% was peripheral type. For distribution of these 65 cases, 60% showed right lung involvement and 40% showed left lung involvement.

Granulomatous Lesions of the Colon

The study consists of an analysis of 39 cases of all kinds of granulomatous lesions in the colon observed at our X-ray department during 3year period between Jan. 1960. and the end of. 1962. Of these 39, 13 cases were Crohn's disease of the colon and 15 cases were tuberculous colitis. The remaining 11 cases were due to ulcerative colitis 3, amoebic colitis 4, and non-specific pericolitis 4. 17 males and 22 females were seen and, the peak incidence was from 40 to 49 years of age. The diagnosis of each granulomatous lesion was confirmed by tissue examination obtained by exploratory celiotomy or by biopsy. Crohn's disease and tuberculos colitis were more frequently encountered in the large bowel rather than in the ileo-cecal region. Granulomatous lesions in the colon must be differentiated from a number of causes of large bowel pathology e. g. carcinoma or lymphoma. The diseases with which it is more commonly confused are ulcerative colitis, tuberculous colitis, Crohn's disease and amoebic colitis. X-ray features of each of these granulomatous lesions are presented in detail and the points of differential diagnosis are discussed.
