Abstract Background Dengue fever is a major public health problem with an increased incidence in recent years. Gall bladder wall thickening has been reported as one of the most common findings in dengue fever. There is a paucity of literature regarding the various patterns of gall bladder wall thickening in dengue fever and their significance in predicting the severity of disease. Methodology and Significant Findings Out of 93 seropositive patients included in the study, 54 patients with dengue fever had gall bladder wall thickening. 4 patterns of gall bladder wall thickening are demonstrated in this study. A uniform echogenic pattern in 20 patients, striated or tram track pattern in 11 patients, an asymmetric pattern in 2 patients and a honeycombing pattern in 21 patients. The range of patterns of wall thickening included normal wall thickening or uniform echogenic wall thickening in DF without warning signs, a striated or tram track pattern, and a honeycomb pattern in severe DF. Serial ultrasound done on consecutive alternate days revealed a change in the pattern of gall bladder wall thickening according to the severity of disease. Conclusion The present study revealed 4 distinct patterns of gall bladder wall thickening. The uniform echogenic pattern was found to be more prevalent in dengue fever without warning signs, while the honeycomb pattern was found to be more prevalent in severe dengue fever. A change in the pattern of gall bladder wall thickening on subsequent serial ultrasound can predict the severity of the disease.

AbstractIntroduction: Radiographic findings of dengue fever have not yet been clearly elucidated in relation to clinical and serological findings, despite the fact that two-fifths of the world population lives in areas where the virus is endemic. The current study is a retrospective analyzis of ultrasonographic (USG) features of patients presenting with probable dengue fever during the outbreak of DF of 2006 in North India.Methods: Case records of a 169 patients with probable dengue fiver were included. Ten individual sonographic parameters were reviewed vis-à-vis ascites, hepatomegaly, splenomegaly, gall bladder wall edema (GBWE), pleural effusion (right or left or both), pericardial effusion, pericholecystic collection, perinephric collection. Subjects who had GB wall thickness >3 mm as measured on ultrasound were identified as positive for GBWE. The cases were analyzed in view of their serological profile.Results: The mean age of the subjects was 27.9 +/− 13.4 years. The mean value of the platelet count was 57.4 +/− 22.3 x 103/cmm. The most common ultrasonographic feature was ascites (126, 74.6%) followed by gall bladder wall edema (122, 72%), hepatomegaly (78, 46.2%), splenomegaly (66, 39.1%) and pericholecystic collection (63, 37.3%); 48 (28.4%) subjects demonstrated evidence of pleural effusion on the right side, while 19 (11.2%) had bilateral effusion. None of the subjects had an isolated left pleural effusion. Twenty-seven (16%) subjects reported bleeding manifestations in the form of petechiae and five (3%) developed renal dysfunction. Presence of pleural and pericardial effusions was found to be specific while ascites and GBWE were identified as highly sensitive markers for seropositive Primary DF.Conclusions: Ultrasonographic evidence of ascites, pleuro-pericardial effusion, and gallbladder wall edema are rapidly aquired, non-invasive markers of dengue and can be helpful before serological investigations become available. These findings may indicate severity and may herald the onset of bleeding (petechiae) or predict the development of acute renal dysfunction.

A simple and reproducible method has been developed for following fluid transport by an in vitro preparation of mammalian gall bladder, based upon weighing the organ at 5 minute intervals. Both guinea pig and rabbit gall bladders transport NaCl and water in isotonic proportions from lumen to serosa. In the rabbit bicarbonate stimulates transport, but there is no need for exogenous glucose. The transport rate is not affected by removal of potassium from the bathing solutions. Albumin causes a transient weight loss from the gall bladder wall, apparently by making the serosal smooth muscle fibers contract. Active NaCl transport can carry water against osmotic gradients of up to two atmospheres. Under passive conditions water may also move against its activity gradient in the presence of a permeating solute. The significance of water movement against osmotic gradients during active solute transport is discussed.

Background: Dengue Fever is an acute mosquito transmitted viral infection caused by one of the 4 serotypes of the genus flavivirus which has become a major international public health problem. The diagnosis of DF is often delayed owing to time taken for availability of serology test results. Moreover, this test is expensive and not widely available. Ultrasonography (USG) is a cheap, rapid and widely available non-invasive imaging method. In recent years several studies concluded that Ultrasonography of the chest and abdomen can be an important adjunct to clinical profile in diagnosis of DF and diagnosis can be made early in the course of the disease compared with other modes of diagnosis. The aim of  the study is to demonstrate the ultrasound findings of dengue fever and also evaluate the specificity of gall bladder findings in dengue fever. Subjects and Methods: We conducted a prospective study in Govt Medical College& Hospital, Srikakulam and Konaseema Institute of Medical Sciences, Amalapuram, A.P. Study included 50 patients referred to the department of Radio-Diagnosis and Imaging for Ultrasonography with clinical suspicion of dengue fever, during a period of July 2018 to December 2019. USG of the abdomen, pelvis and chest was performed in  all cases and findings were noted. Dengue serology was performed later and all the ultrasound findings were correlated with dengue serology. Results:  In our study of 50 patients all the patients studied were diagnosed with dengue fever based on dengue serology. In our study, 100%  of our patients diagnosed with DF (by dengue serology) showed gall bladder wall thickening, 88% showed splenomegaly, 44% showed ascites. Pleural effusion was present in 30% of which 66.66% of pleural effusion was bilateral and the rest 33.33% was right sided. Isolated left sided pleural effusion was not found in our study. Hepatomegaly was present in 28% of our patients. In our study mortality and complications from dengue fever were not seen. Conclusion: Ultrasound findings in dengue fever are gall bladder wall thickening, splenomegaly, ascites, pleural effusion and hepatomegaly. In an area where DF is an epidemic, when Ultrasonography shows gall bladder wall thickening in a febrile patient with thrombocytopenia DF should be suggested On Ultrasonography, when there is gall bladder wall thickening, splenomegaly, ascites, and pleural effusion in a febrile patient with thrombocytopenia in a DF epidemic area a diagnosis of DF should be considered in a differential diagnosis until proved otherwise.

Background: Histopathological changes induced by gall stone disease or cholelithiasis are diverse including acute inflammation, chronic inflammation, glandular hyperplasia, granulomatous inflammation, cholesterosis, dysplasia and carcinoma. Hence, this study was planned to assess gallbladder mucosal changes in patients undergoing laparoscopic cholecystectomy (LC) and it’s correlation with number and types of stone.Methods: A total of 50 patients with symptomatic cholelithiasis scheduled to undergo laproscopic cholecystectomy (LC) after written and informed consent from October 2015 to October 2018 at Teerthanker Mahaveer Medical College and Research Centre, Moradabad were followed prospectively. Preoperative biochemical profile and ultrasonography of whole abdomen of all the patients was obtained. LC was done under the hands of the skilled and experienced surgeons. Morphologic profile of gallstones was recorded and analysed. Gallbladder mucosal tissues were sent to general pathology department for analysis. Histopathological typing of all the gallbladder mucosal specimens was done and was correlated with the number and type of gallstones.Results: In majority (76%) cases, cholecystitis was found. Hyperplasia was seen in 10% patients. Cholecystitis with metaplasia in 10 percent of the cases and carcinoma in 2 percent of the cases. While correlating the gallbladder mucosal response with the number and type of stones, non-significant results were obtained.Conclusions: There might be some association between gall bladder mucosal changes and gall stone. We cannot say an etiologic and effective correlation from the results of this study; possible mechanism may be gall stone erodes gall bladder wall constantly over a period of time which may constitute a risk. While correlating gallbladder mucosal response with the number and type of stones, non-significant results were obtained.

Background: Laparoscopic cholecystectomy (LC) has become the gold standard treatment for gallstone disease. Though mostly safe occasionally it can be difficult due to various problems faced during surgical procedure. Anticipation of likely difficulty can help in avoiding complications.Methods: With the aim of identifying various predictors of difficulty and their correlation with likely difficulty this prospective study on 50 adults undergoing laparoscopic cholecystectomy for symptomatic cholelithiasis was undertaken. Various clinical, radiological and biochemical predictors and frequency and type of intraoperative difficulty was recorded.Results: In present study adverse clinical factors only showed significant predictive value (p value - 0.005). Adverse radiological predictors although showing trend towards, did not achieve statistical significance (p value 0.065). In clinical predictors duration of symptoms >1yr, History of acute cholecystitis and BMI >30 showed statistically significant association. Age >50yrs, Male gender, radiological predictors (Thickened gall bladder wall, small contracted gall bladder, Single large impacted stone) and deranged LFT did not show significant predictive value.Conclusions: Clinical predictors are most reliable factors. Use of good clinical judgement regarding possibility of and likely difficulty along with understanding of available resources is important in making decision in each case.
