A Study of the Effect of Changes in Ano-Rectal Function after Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: It has been suggested that hysterectomy has a disturbing influence on bowel function, mainly constipation. We performed a prospective study to assess the changes of ano-rectal physiology after hysterectomy. METHODS: Fourteen consecutive patients were assessed before and two months after hysterectomy. A detail questionnaire was devised to allow assessment of bowel function and ano-rectal pressure test and balloon expulsion test were performed before and after hysterectomy. The parameters measured in ano-rectal pressure test included the minimal sensible volume, ano-rectal resting pressure, maximal squeezing pressure, recto-anal inhibitory reflex and balloon expulsion test. Data analysis was carried out by paired t-test. Statistical significance was inferred when the p value was0.05). There were no significant changes in ano-rectal pressure test after hysterectomy. The disturbance of balloon expulsion capacity was increased in four patients after hysterectomy(29%). CONCLUSION: Our results demonstrate that hysterectomy does not cause a decrease in ano-rectal pressure and rectal sensitivity, but has an adverse effect on rectal expulsion capacity in a some of patients.

A Case of Idiopathic Segmental Ileal Dilatation with Acute Intestinal Bleeding / 대한내과학회지

Idiopathic segmental ileal dilatation is a rare congenital condition in which the caliber of the bowel lumen increases locally without distal luminal obstruction or thickening of the muscle coats in involved lumen. Congenital abnormalities such as exomphalos, malrotation of the midgut, and Meckel's diverticulum are found frequently in the patients with segmental dilatation of the small bowel. Intermittent abdominal pain or anemia may be the symptoms of segmental dilatation of the small bowel in infants, children and occasionally adults. The radiologic finding in barium studies of the small bowel is characteristic axial segmental dilatation. The pathologic finding is nonspecific ulcer and mild congestion, but it has normal nervous system and smooth muscle bundle. There are no evidence of ischemic changes, inflammatory changes or neoplastic changes. The condition can be cured with surgical excision of the dilated segment. A case of idiopathic segmental ileal dilatation associated with melena and recurrent abdominal pain diagnosed by enteroclysis in a 47 years old man was presented with brief review of the literature.

Unusual Endoscopic Retrograde Cholangiographic Finding in a Case of Xanthogranulomatous Cholecystitis / 대한소화기내시경학회지

Xanthogranulomatous cholecystitis is a rare form of chronic gallbladder inflammation that is characterized by a severe proliferative fibrosis and has rarely been described in the radiologic literature. Like xanthogranulomatous pyelonephritis, it is an entirely benign but unusual expression of a reactive process and may be confused with a malignant neoplasm. Histologically, foamy histiocytes, multinucleated giant cells, other inflammatory cells, fibrous reaction with spindle cells, cholesterol cleft and noncaseating granuloma were found. Treatment of this benign inflammatory condition requires cholecystectomy to remove the focus of inflammation, control subsequent infection and relieve symptoms A case of xanthogranulomatous cholecystitis mimiking carcinoma of the gallbladder on abdominal USG, abdominal CT, and ERCP examination is presented with brief review of the literature.

A Case of Colonic Tuberculosis Cured by Secondary Anti - Tuberculosis Medicine / 대한소화기내시경학회지

Tuberculosis is common disease in developing countries manifested by multi-organ involvement. Although the incidence of tuberculosis has been reducing recently due to the advancement of anti-tuberculosis chemotherapy, improvement of public health, and early diagnosis, the rate is still higher in developing countries. The diagnasis of colonic tubcrculosis is difficult due to its frequency, vague manifestation, and difficulty in confirming the disease process. Fortunately, the advent of flexible colonoscopy has provided an opportunity to confirm the diagnosis of colonic tuberculosis, however biopsy can frequently leveal false negative results. A-27-year-old man was admitted with a 2 week history of rectal bleeding. He complained of anorexia, abdominal pain, and weight loss. Routine laboratory tests and chest X-ray findings were within normal limits, with the exception of left pleural thickening. A colonoscopy showed irregular and small, multiple, and shallow polypoid mucosal lesions in the ascending colon and multiple ulcers in the transverse colon. Multiple colonic biopsies suggested tuberculosis. After three months of prirnary anti-tuberculosis medica tion, the patient showed slightly improved coiono- scopic findings. Follow-up colono- scopic findings revealed more aggrevation and chest X-ray findings showed multiple patch consolidation in the left lung field. Primary anti-tuberculosis medication was stopped and substituted for secondary anti-tuberculosis medication. When clinical and colonoscopic methods are found to be compatible with intestinal tuberculosis in countries with a high prevalence of colonic tuberculosis, a therapeutic trial with an antituberculosis agent is usually considered. In a failed therapeutic trial, considerations must be made not only to other inflammatory bowel diseases such as crohn's disease, but also to multi-drug resistance tuberculosis.

A Case of Small Cell Carcinoma of Gallbladder / 대한내과학회지

Carcinoma of the gallbladder is relatively rare malignancy usually found in an elderly, predominantly female population. Histologically, adenocarcinoma predominate, with only 10% to 15% being of other varieties(small cell carcinoma and others). Small cell carcinoma of the gallbladder is a rare lesion and predominantly a disease of older women with clinical history of stones. These tumors show an aggressive clinical course and death usually occurs with in a few months of the diagnosis. The diagnosis of small cell carcinoma should be based on cell morphology, histologic pattern and immunohistochemical study. Correct diagnosis is important not only because these tumors give rise to endocrine syndromes, but also because the chemotherapeutic approach to small cell carcinoma differs from that for adenocarcinoma.

Hemostatic Effect of Endoscopic Hemoclip Method, Hypertonic Saline Epinephrine Injection Method and Their Combined Method for Bleeding Peptic Ulcer / 대한소화기내시경학회지

BACKGROUND: Bleeding peptic ulcer is the most common cause of upper gastrointestinal bleeding. Various different endoscopic hemostatic methods were introduced to treat bleeding peptic ulcer. Many studies reported the efficacy and comparision of various methods. Endoscopic injection therapy is the most comman method among them because it is inexpensive and easy in use. Complications of injection therapy such as aggravation of bleeding, tissue neerosis and perforation were repoted rarely. Recently endoscopic hemoclipping method is considered to be safe and effective hemostatic method for upper gastrointestinal bleeding. METHODS: During the period between January 1993 and August 1996, we have conducted clinical trial and retrospective analysis among 100 patients in whom active bleeding or visible vessel was identified. RESULTS: 1) Three groups was divided, Hemoclip group 26 cases, Hypertonic Saline Epinephrine(HSE) group 59 cases, Combination group 15 cases. 2) The sources of bleeding in Hemoclip group were gastric ulcer in 23 Cases and duodenal ulcer in 3 cases, and in HSE group, gastric ulcer in 44 case, duodenal ulcer 14 cases and stomal ulcer in one case, and in combination group, gastric ulcer in 10 cases, duodenal ulcer in 3 cases and stomal ulcer in two cases. HSE and combination method were performed more than Hemoclip method in duodenal ulcer(23.7% and 20.0% versus 11.5%). 3) As the stigmata of bleeding in Hemoclip and HSE and Combination group, spurting were seen in 5 cases and 3 cases and 4 cases, and oozing in 10 cases and 17 cases and 3 cases, and nonbleeding visible vessel in 11 cases and 39 cases and 8 cases, respectively. Hemoclip method was performed more than HSE method in active bleeding state(57.6% versus 33.9%). 4) Initial hemostasis was achieved in 24 cases(92.3%) in Hemoclip group and 52 cases(88.1%) in HSE group, 13 cases(86.7%) in Combination group. 5) The rebleeding developed in 1 case(4.2%) in Hemoclip group and 8 cases(15.4%) in HSE group and 1 case(7.6%) in Combination group, the emergent operation was undewent 2 cases(7.7%) in Hemoclip group and 10 cases(17.0%) in HSE group and 1 case(6.7%) in Combination group, respectively. 6) The death was noticed in 1 cases(3.9%) in Hemoclip group and 2 cases(3.4%) in HSE group and 2 case(13.3%) in Combination group, repectively. 7) Permanent hemostasis by only endoscopic treatment was achieved in 24 cases(92.3%) in Hemoclip group and 48 cases(81.4%) in HSE group, 12 cases(80.0%) in Combination group. 8) Complication was noticed only in HSE group, aggravation of bleeding in one case and hematoma in two cases. CONCLUSION: Hemoclip method was effective hemostatic method same as HSE injection method, and safe method weth low complication in bleeding peptic ulcer. We suggest more detail selection of endoscopic hemostatic method in variously individualized endoscopic features.

Cushing's Disease Due to ACTH Producing Pituitary Carcinoma / 대한내분비학회지

Primary carcinoma of the pituitary is only rarely reported. About half of the reported cases are nonfunctional. It is generally agreed that the presence of distant metastasis is required to clearly establish the diagnosis of pituitary carcinoma. We have experienced a case of ACTH-producing pituitary carcinoma causing Cushing's syndrome which could be diagnosed by histologic features only without evidence of distant metastasis. A 35-year-old female with Cushingoid appearance was diagnosed as Cushing's disease after biochemical and neuroradiological evaluation. Near total removal of the pituitary tumor was performed. By histopathologic examination, the tumor revealed evidences of histological malignancy such as prominent nuclear pleomorphism, frequent mitoses and extensive tumor necrosis. Pseudosarcomatous components were also noted. By immunohistochemical studies, the tumor cells expressed ACTH. However, there was no evidence of distant metastasis at the initial operation. She was diagnosed as having ACTH producing pituitary carcinoma by histologic feature only. One month later, she complained progressive nausea and vomiting, and follow-up brain MRI revealed regrowing pituitary mass. She was reoperated and near total tumor bulk was removed again followed by radiotherapy with 5580 rads. Four month after the second operation, she developed generalized tonic clonic seizure. Brain CT showed multiple enhancing nodules on left temporal and frontal lobes, and around falx cerebri. She refused further treatment and was managed only with anticonvalsants. About month after discharge she died at home.

The thrombolytic effect of lumbrokinase is not as potent as urokinase in a rabbit cerebral embolism model

The purpose of the present study is to determine whether lumbrokinase has an in vivo thrombolytic effect in a rabbit cerebral embolism model. In our previous studies, we found that lumbrokinase, an extract from Korean earth worms, has a strong in vitro fibrinolytic effect without the presence of plasminogen and significant in vivo thrombolytic effects of lumbrokinase in a rat human-clot-induced cerebral embolism model. We established the cerebral embolism model in rabbits by injecting a piece of human clot into the internal carotid artery via the external carotid artery and confirmed the occlusion with angiography. Twenty one rabbits were divided into three groups and 5cc of saline, urokinase of 50,000 u/ml, and equipotent LK were injected intraarterially for 30 minutes into each group of 7 animals. Ten minutes after the end of infusion, an angiogram was performed to confirm the recanalization. Clot lysis occurred in one, six, and one animals in the saline, urokinase and lumbrokinase treated groups respectively. With regard to its in vitro effect, lumbrokinase is not as potent in vivo. Further investigation should be performed to determine the cause of its weakened in vivo effect and to develop a method to potentiate it.
