Adenomyomatosis of the gallbladder is Characterized by hyperplastic changes including overgrowth of the mucosa, thickening of the muscle wall, and intramural diverticula, crypts, or sinus tracts(Rokitaasky-Aschoff sinuses). The main diagnostic test for the detection of this disease is oral cholecystography but it's use is being decreased. Recently, Ultrasound, ERCP, and CT have been used for diagnosis. We present a report of case in whom ademomyomatosis of gallbladder was disgnosed on ultrasound and ERCP and confirmed by surgery. The essential feactures of ultrasound and ERCP diagnosis are discussed.

BACKGROUND: Obstructive sleep apnea (OSA) is a common sleep disorder that causes daytime dysfunction and cardiovascular diseases. Nocturnal polysomnography (NPSG) is the standard method of evaluating OSA; however, it is time-consuming, inconvenient, and expensive. Selective performance of NPSG would be possible if we could better predict those who are more likely to have clinically significant OSA. The aim of this study is to define clinical and anthropometric predictors of OSA. METHODS: We included 100 consecutive patients in whom OSA was clinically suspected. Structured sleep interview, anthropometric measurement, and NPSG were performed in all subjects. Presence of OSA was defined when the apnea-hypopnea index was five or more. Parameters from sleep interview and anthropometric data were investigated with multiple logistic regression using the SAS program (ver 8.1, USA) to identify independent predictors of OSA. RESULTS: OSA was diagnosed in seventy-six patients after NPSG. Univariate analysis showed that the male sex, co-existing diabetes, overweight (BMI>or=25), habitual alcohol drinking, large neck circumference (>or=40 cm), high waist circumference/hip circumference (WC/HC) ratio (>or=0.94), and observed apnea were significantly more frequent in OSA patients (p<0.05). Using multivariate analysis, large neck circumference (>or=40 cm) (adjusted OR=4.43, 95% CI: 1.05~18.61) and high WC/HC ratio (adjusted OR=3.48, 95% CI: 1.12~10.80) were found to be the independent predictors of OSA on the NPSG. CONCLUSIONS: We report the predictors of OSA that could be easily identified by clinical and anthropometric evaluations before performing NPSG. This might aid the clinical decision whether or not to perform NPSG in subjects with clinically suspected OSA syndrome.

PURPOSE: Brain metastasis is infrequent in colorectal cancer patients. The purpose of this study was to analyze the clinical characteristics including the survival, type of treatment, and metastatic patterns of brain metastasis in colorectal cancer. METHODS: Between January 1993 and September 2002, we analyzed 2,019 surgical patients with colorectal carcinoma operated at Korea Cancer Center Hospital. Among these patients, 13 patients were identified with metastatic colorectal cancer to the brain. The medical records of these patients were reviewed retrospectively and survival analysis was performed. RESULTS: During the study period, the incidence of brain metastasis of colorectal cancer was 0.6%. Male-to-female ratio was 1:1.6. Mean age was 55.2+/-9.7 years and median age was 56 years (34~67years). The most frequent primary tumor site was the rectum (11 cases, 84.6%). and the most frequent symptom of brain metastasis was headache. According to the TNM staging system, there were 1 case in stage II, 8 cases in stage III, and 4 cases in stage IV at the time of initial diagnosis of colorectal cancer. Brain metastases were often occurred concurrently with lung metastases (9 cases, 69.2%), otherwise solitary brain metastasis was found in 4 cases. Between the diagnosis of primary cancer and the diagnosis of brain metastasis, the mean interval was 25.9+/-6.9 months and the median interval was 16 months (5~97) in stage II and III patients. The mean survival time after the diagnosis of brain metastasis was 18.5 months for patients who underwent surgery and 3.3 months for patients who received non-surgical therapy. CONCLUSIONS: Brain metastasis of colorectal cancer is relatively uncommon and the incidence is significantly low, commonly more or less than 1%. It is often accompanied by pulmonary metastasis. The results of this study show that surgical resection may increase the survival of these patients. Though inability to the awareness of the possibility and early diagnosis of brain metastasis in colorectal cancer could affect the poor prognosis, aggressive treatment in suitable cases might enhance the survival for this group of patients.

PURPOSE: A duodenal stump fistula is one of the most severe complications after gastrectomy for gastric cancer. We aimed to analyze the risk factors for this problem, and to identify the methods used for its prevention and management. METHODS: We retrospectively reviewed the clinical data of 716 consecutive patients who underwent curative gastrectomy with a duodenal stump for gastric cancer between 2008 and 2013. RESULTS: A duodenal stump fistula occurred in 16 patients (2.2%) and there were 2 deaths in this group. Univariate analysis revealed age >60 years (odds ratio [OR], 3.09; 95% confidence interval [CI], 0.99-9.66), multiple comorbidities (OR, 4.23; 95% CI, 1.50-11.92), clinical T stage (OR, 2.91; 95% CI, 1.045-8.10), and gastric outlet obstruction (OR, 8.64; 95% CI, 2.61-28.61) to be significant factors for developing a duodenal stump fistula. Multivariate analysis identified multiple comorbidities (OR, 3.92; 95% CI, 1.30-11.80) and gastric outlet obstruction (OR, 5.62; 95% CI, 1.45-21.71) as predictors of this complication. CONCLUSION: Multiple comorbidities and gastric outlet obstruction were the main risk factors for a duodenal stump fistula. Therefore, preventive methods and aggressive management should be applied for patients at high risk.

PURPOSE: Defecography is a dynamic investigation which can influence clinical decision making in patients with pelvic outlet obstructive disease (POOD). The current study was designed to establish defecographic findings in patients with POOD. Specifically, we sought to assess the physiologic characteristics of categorized types by using anorectal physiologic tests. METHODS: One hundred seven patients (disease group; 45 men, 62 women) with POOD were retrospectively categorized as type I [non-relaxation of puborectalis (NRPR) only, n=19], type II [NRPR and rectocele, n=20], type III [NRPR, rectocele, and dynamic perineal descent (PD), n=17], type IV [deformed rectocele, mild-to-moderate fixed PD, and absence of NRPR, n=29], and type V [rectocele, severe fixed PD, and absence of NRPR, n=20] on the bases of defecographic findings. The ability to evacuate, the frequency/degree of intarectal intussusception (IRI), and the size of the rectocele were evaulated in these defecographic types of POOD. Age, duration of symptoms, and the physiologic findings of anal manometry and EMG/PNTML were compared for the five types. Eighteen healthy volunteers who had no defecation difficulty were used to estimate the normal findings of defecography. RESULTS: The age and the sex showed no significant differences among the types. The duration of symptoms was gradually lengthened from type I to V (P<0.01). The ability to evacuate in patients with POOD was significantly worse (failed to effectively evacuate) compared to that in the healthy volunteers (P<0.01). The frequency of IRI was increased more and more from type I to V (P<0.01). The size of the rectocele was significantly increased in types V compared to the other types (P<0.01). Manometric and neurologic findings, including EMG/PNTML, revealed no significant differences among the types. CONCLUSIONS: Even though there were no specific differences in the findings of the anal manometric and neurologic tests, the evacuation dynamics; were different in the five defecographic categories of patients with POOD. Specifically, these differences were relevants to the presence of NRPR, rectoceles, IRI, and perineal descent.

PURPOSE: Since the first case of bone metastasis of a rectal carcinoma was reported by Curling in 1870, bone metastasis in primary colorectal cancer has remained uncommon event. The aim of our study was to gain insight into the clinical characteristics of bone metastasis of colorectal cancer. METHODS: This is a 10-year retrospective study that covers patients with bone metastasis of colorectal cancer in the Department of Surgery, Korea Cancer Center Hospital, from Jan. 1993. RESULTS: In a total of 1461 cases of primary colorectal cancer treated in the same period, the clinical analysis was possible in 1356 cases. Of these, 53 cases showed bone metastasis. The incidence of bone metastasis was 3.9 Thirteen cases (25%) had bone metastasis only whereas 40 cases (75%) had bone metastasis combined with metastases of other organs. The most frequent site of bone metastasis was the vertebral bone (38, 71.7%), especially the thoracic spine (21, 39.6%). The median survival after onset of bone metastasis was 4.4 months, including 9.8 months in the bone-metastasis-only group and 3.5 months in bone metastasis with other-site- metastasis group. However, there was no significant difference in survival rate from the onset of bone metastasis between the two groups (P=0.3876). CONCLUSIONS: If the colorectal cancer patient has complaint of bony pain, bone metastasis should be considered even though it is a rare event. However, most cases of bone metastasis occur with metastases of other organs. Management is often limited to simple procedures intended to relieve pain in the terminal phase of the disease.
