The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.

Helicobacter pylori is a gram-negative pathogen commonly associated with peptic ulcer disease and gastric cancer. H. pylori infection has also been reported in cholelithiasis, cholecystitis, gallbladder polyps, and biliary tract cancers. However, the association between H. pylori and gallbladder and biliary tract pathologies remains unclear due to the paucity of literature. In response to the current literature gap, we aim to review and provide an updated summary of the association between H. pylori with gallbladder and biliary tract diseases and its impact on their clinical management. Relevant peer-reviewed studies were retrieved from Medline, PubMed, Embase, and Cochrane databases. We found that H. pylori infection was associated with cholelithiasis, chronic cholecystitis, biliary tract cancer, primary sclerosing cholangitis, and primary biliary cholangitis but not with gallbladder polyps. While causal links have been reported, prospective longitudinal studies are required to conclude the association between H. pylori and gallbladder pathologies. Clinicians should be aware of the implications that H. pylori infection has on the management of these diseases.

Gallstone disease is a major surgical problem in many populations; it is probably related to diet, especially excessive consumption of meat. The objective of this study was to determine the chemical composition of gallstones and their association with neoplastic changes including cholangiocarcinomas in cholecystectomised patients. The chemical composition of gallstones from 40 patients (8 males and 32 females) was analyzed. This is a prospective study performed in Baquba teaching hospital in the period from 1/10/2012 to 1/1/2013 in which we collected the gallstones for the patients who underwent cholecystectomy, whether open or laparoscopic. The stones were classified according to their chemical composition as a mixed stones (MS), and examined using a stone analysis set (chemical qualitative method) for calcium, magnesium, phosphate, uric acid and oxalate which was used reagent for qualitative determination of main individual components of stones. The results of this study showed the highest incidence of gallstones in the age group 40-49 was 13 cases followed by 11, 8 and 4 cases for age groups 30-39, 50-59, 20-29 and 60 and above, respectively. The chemical analysis showed the majority of gallstones were mixed, 38 containing calcium followed by 37 cases with uric acid, 28 with magnesium, and 25 and 22 stones with oxalate and phosphate, respectively. Microscopically, we confirmed neoplastic changes (17.5%) as cholangiocarcinomas (CCCs) (7.55%) and dysplastic cells of carcinoma in situ in 4 (10%), 31 (77.5%) cases were chronic cholecystitis and 2 (5%) cases were acute cholecystitis with empyema out of bile duct disorders patients. In conclusion, majority of cases had mixed gallstones that involved five and four of inorganic chemicals of calcium, magnesium and phosphate, the highest incidence of gallstones in age group 40-49 years old was 13 cases, and neoplastic changes were confirmed (17.5%) including CCCs, (7.5%) and dysplastic cells of carcinoma in situ (10%), while 31 (77.5%) cases were chronic cholecystitis.

Laparoscopic cholecystectomy has been increasingly used because of several advantages, less pain, better expectation for cosmesis (requires small incisions), and more rapid recovery compared with open cholecystectomy. Oral intake is tolerated on the day of operation or on the next. In this study, we evaluated the effectiveness and safety of laparoscopic cholecystectomy in children. Nine cases of laparoscopic cholecystectomy for acute and chronic cholecystitis in children were performed at Asan Medical Center between April 2002 and April 2004. Laparoscopic cholecystectomy was performed on a total of 10 patients, but one of them was excluded because of the simultaneous splenectomy for sickle cell anemia. Clinical presentation, operative findings, operation time, length of hospital stay, and postoperative complications were analyzed. Mean age was 10.4 (4.15) years, and only 3 of patients were less than 10 years. One patient was female. In 8 the diagnosis was calculous cholecystitis. Mild adhesions were found in 3 cases and intraoperative bile leakage in 2. There was no conversion to open surgery and there were no vascular, bowel, or bile duct injuries. Mean operation time was 82.2 (20.160) minutes; mean length of hospital stay was 2.1 (1.3) day. There was no postoperative complication. Laparoscopic cholecystectomy in children was remarkably free of side effects and complications and had a short recovery time. Laparoscopic cholecystectomy for cholecystitis is considered to be a standard procedure in children.

The selection of meaningful clinical tests and its reference values from a high-dimensional clinical data with imbalanced class distribution, one class is represented by a large number of examples while the other is represented by only a few, is an important issue for differential diagnosis between similar diseases, but difficult. For this purpose, this study introduces methods based on the concepts of both discernibility matrix and function in rough set theory (RST) with two discretization approaches, equal width and frequency discretization. Here these discretization approaches are used to define the reference values for clinical tests, and the discernibility matrix and function are used to extract a subset of significant clinical tests from the translated nominal attribute values. To show its applicability in the differential diagnosis problem, we have applied it to extract the significant clinical tests and its reference values between normal (N = 351) and abnormal group (N = 101) with either cholecystitis or cholelithiasis disease. In addition, we investigated not only the selected significant clinical tests and the variations of its reference values, but also the average predictive accuracies on four evaluation criteria, i.e., accuracy, sensitivity, specificity, and geometric mean, during l0-fold cross validation. From the experimental results, we confirmed that two discretization approaches based rough set approximation methods with relative frequency give better results than those with absolute frequency, in the evaluation criteria (i.e., average geometric mean). Thus it shows that the prediction model using relative frequency can be used effectively in classification and prediction problems of the clinical data with imbalanced class distribution.

Backgrounds/Aims: Endoscopic retrograde cholangiopancreatography-guided gallbladder drainage (ERGD) is an alternative to percutaneous cholecystostomy (PTC) for hospitalized acute cholecystitis (AC) patients. Methods: We retrospectively analyzed propensity score matched (PSM) AC hospitalizations using the National Inpatient Sample database between 2016 and 2019 to compare the outcomes of ERGD and PTC. Results: After PSM, there were 3,360 AC hospitalizations, with 48.8% undergoing PTC and 51.2% undergoing ERGD. There was no difference in median length of stay between the PTC and ERGD cohorts (p = 0.110). There was a higher median hospitalization cost in the ERGD cohort, $62,562 (interquartile range [IQR] $40,707-97,978) compared to PTC, $40,413 (IQR $25,244-65,608; p < 0.001). The 30-day inpatient mortality was significantly lower in hospitalizations with ERGD compared to PTC (adjusted hazard ratio 0.16, 95% confidence interval [CI]: 0.1-0.41; p < 0.001). There was no difference in association with blood transfusions, acute renal failure, ileus, small bowel obstruction, and open cholecystectomy conversion (p > 0.05) between hospitalizations with ERGD and PTC. There was lower association of acute hypoxic respiratory failure (adjusted ratio [AOR] 0.46, 95% CI: 0.29-0.72; p = 0.001), hypovolemia (AOR 0.66, 95% CI: 0.49-0.82; p = 0.009) and higher association of lower gastrointestinal bleed (AOR 1.94, 95% CI: 1.48-2.54; p < 0.001) with ERGD compared to PTC. Conclusions: ERGD is a safer alternative to PTC in patients with AC. The risk complications are lower in ERGD compared to PTC but no difference exists based on mortality or conversion to open cholecystectomy.

황색육아종성 염증은 드문 염증 반응으로서 조직병리학적으로 지방을 함유한 큰포식세포의 집단인 황색종의 소견이 특징적이다. 이 질환은 공격적 성향을 보여 종종 주변으로 국소 침습하지만, 원격 장기를 침범하는 경우는 매우 드물어 전신질환이 있는 경우에 극히 예외적으로 관찰된다. 우리는 영상의학적 검사에서 주변부 침윤을 동반한 낭성 병변으로 보이는 증례에서 심한 황색육아종성 담낭염과 드물지만 국소성 황색육아종성 신우신염을 의심하였고 수술적 절제를 통해 병리학적으로 황색육아종성 담낭염에 연관되어 병발한 국소형 황색육아종성 신우신염을 확진하였다. 우리가 아는 한, 황색육아종성 담낭염에 국소성 황색육아종성 신우신염이 병발한 경우는 이전에 보고된 바가 없다. 또한, MRI T2 강조 영상에서의 낭성 병변 주위로 아마도 황색육아종성 염증의 출혈과 섬유화를 반영할 것으로 추정되는 저신호 강도 주변부를 확인하였다.

목적 황색육아종성 담낭염을 벽비후형 담낭암으로부터 감별진단하기 위한 자기공명영상(MRI) 점수체계를 고안하고, 그 점수체계의 진단능을 영상의학과 의사의 시각적 평가와 비교하고자 한다. 대상과 방법 복부 MRI 및 수술을 시행한 각각 황색육아종성 담낭염과 벽비후형 담낭암으로 진단된 23명과 35명의 환자를 후향적으로 분석하였다. 세 명의 영상의학과 의사가 모든 MRI 소견을 분석하였다. 저자들은 이러한 MRI 소견을 이용하여 벽비후형 담낭암으로부터 황색육아종성 담낭염을 감별진단하기 위한 점수체계를 고안하였고 이 점수체계의 진단능을 수신자 운영 특성 곡선의 곡선 하 면적을 영상의학과 의사의 시각적 평가와 비교하였다. 결과 9가지의 MRI 소견이 두 질환의 감별에 유의미한 차이를 보였다: 미만형 벽 비후(p < 0.001), 점막 균일성(p = 0.002), 벽내 T2 고신호강호(p < 0.001), 점막 당김(p = 0.016), 담낭 결석(p < 0.001), T1 중등도 혹은 고신호강도(p = 0.033), 확산 제한(p = 0.005), 조영증강 패턴(p < 0.001), 조영증강 최고점 시기(p = 0.008). MRI 점수체계는 곡선 하 면적이 0.972로 뛰어난 진단능을 나타내었고 이는 영상의학과 의사의 시각적 평가보다 유의미하게 높았다. 결론 MRI 점수체계는 황색육아종성 담낭염을 벽비후형 담낭암으로부터 감별진단하는 데 있어 영상의학과 의사의 시각적 평가보다 좋은 진단능을 나타내었다.

Purpose: Gallbladder (GB) wall thickening can be found in various conditions unrelated to intrinsic GB disease. We investigated the predisposing etiologies and the outcome of acalculous GB wall thickening in children. Methods: We retrospectively analyzed 67 children with acalculous GB wall thickening who had visited our institute from June 2010 to June 2013. GB wall thickening was defined as a GB wall diameter > 3.5 mm on abdominal ultrasound examination or computed tomography. Underlying diseases associated with GB wall thickening, treatment, and outcomes were studied. Results: There were 36 boys and 31 girls (mean age, $8.5{\pm}4.8years$ [range, 7 months-16 years]). Systemic infection in 24 patients (35.8%), acute hepatitis in 18 (26.9%), systemic disease in 11 (16.4%), hemophagocytic lymphohistiocytosis in 4 (6.0%), acute pancreatitis in 3 (4.5%), and specific liver disease in 3 (4.5%) predisposed patients to GB wall thickening. Systemic infections were caused by bacteria in 10 patients (41.7%), viruses in 5 patients (20.8%), and fungi in 2 patients (8.3%). Systemic diseases observed were systemic lupus erythematosus in 2, drug-induced hypersensitivity in 2, congestive heart failure in 2, renal disorder in 2. Sixty-one patients (91.0%) received symptomatic treatments or treatment for underlying diseases. Five patients (7.5%) died from underlying diseases. Cholecystectomy was performed in 3 patients during treatment of the underlying disease. Conclusion: A wide range of extracholecystic conditions cause diffuse GB wall thickening that resolves spontaneously or with treatment of underlying diseases. Surgical treatments should be avoided if there are no definite clinical manifestations of cholecystitis.
