The effectiveness of image-guided percutaneous catheter drainage in the management of acute pancreatitis-associated pancreatic collections.

PURPOSE: Acute pancreatitis is commonly complicated by the development of pancreatic collections (PCs). Symptomatic PCs warrant drainage, and the available options include percutaneous, endoscopic, and open surgical approaches. The study aimed to assess the therapeutic effectiveness and safety of image guided percutaneous catheter drainage (PCD) in the management of acute pancreatitis related PCs. MATERIAL AND METHODS: This was a single-centre prospective study covering a 4-year study period. Acute pancreatitisrelated PCs complicated by secondary infection or those producing symptoms due to pressure effect on surrounding structures were enrolled and underwent ultrasound or computed tomography (CT)-guided PCD. The patients were followed to assess the success of PCD (defined as clinical, radiological improvement, and the avoidance of surgery) and any PCD-related complications. RESULTS: The study included 60 patients (60% males) with a mean age of 43.1 ± 21.2 years. PCD recorded a success rate of 80% (16/20) for acute peripancreatic fluid collections (APFC) and pancreatic pseudocysts (PPs), 75% (12/16) for walled-off necrosis (WON), and 50% (12/24) for acute necrotic collections (ANCs). Post-PCD surgery (necrosectomy ± distal pancreatectomy) was needed in 50% of ANC and 25% of WON. Only 20% of APFCs/PPs patients required surgical/endoscopic treatment post-PCD. Minor procedure-related complications were seen in 4 (6.6%) patients. CONCLUSION: PCD is an effective, safe, and minimally invasive therapeutic modality with a good success rate in the management of infected/symptomatic PCs.

Isolated left ventricular hypoplasia - A singularity.

Isolated left ventricular hypoplasia is an entity with uncertain natural history and etiology. The presentation could vary from being asymptomatic to sudden death. This form of cardiomyopathy has been reported in infants as well as in adults. This case report aims to alert physicians to this diagnosis and the undeniable advantage of cardiac magnetic resonance.

Cerebrotendinous xanthomatosis - A case report.

Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder resulting from a defective enzyme in bile acid synthesis pathway leading to neurological, ocular, vascular, and musculoskeletal symptoms from deposition of cholestanol and cholesterol in these tissues. We present clinical and imaging features of a 32-year-old female who presented with mental retardation, gait instability and swelling along posterior aspect of both ankles. Imaging studies were performed which revealed spectrum of CTX findings in brain and tendons. Subsequently the diagnosis was confirmed by biopsy and laboratory tests.

Evaluation of various patient-, lesion-, and procedure-related factors on the occurrence of pneumothorax as a complication of CT-guided percutaneous transthoracic needle biopsy.

PURPOSE: To assess the influence of various patient-, lesion-, and procedure-related variables on the occurrence of pneumothorax as a complication of CT-guided percutaneous transthoracic needle biopsy. MATERIAL AND METHODS: In a total of 208 patients, 215 lung/mediastinal lesions (seven patients were biopsied twice) were sampled under CT guidance using coaxial biopsy set via percutaneous transthoracic approach. Incidence of post procedure pneumothorax was seen and the influence of various patient-, lesion-, and procedure-related variables on the frequency of pneumothorax with special emphasis on procedural factors like dwell time and needle-pleural angle was analysed. RESULTS: Pneumothorax occurred in 25.12% (54/215) of patients. Increased incidence of pneumothorax had a statistically significant correlation with age of the patient (p = 0.0020), size (p = 0.0044) and depth (p = 0.0001) of the lesion, and needle-pleural angle (p = 0.0200). Gender of the patient (p = 0.7761), emphysema (p = 0.2724), site of the lesion (p = 0.9320), needle gauge (p = 0.7250), patient position (p = 0.9839), and dwell time (p = 0.9330) had no significant impact on the pneumothorax rate. CONCLUSIONS: This study demonstrated a significant effect of the age of the patient, size and depth of the lesion, and needle-pleural angle on the incidence of post-procedural pneumothorax. Emphysema as such had no effect on pneumothorax rate, but once pneumothorax occurred, emphysematous patients were more likely to be symptomatic, necessitating chest tube placement. Gender of the patient, site of the lesion, patient position during the procedure, and dwell time had no statistically significant relation with the frequency of post-procedural pneumothorax. Surprisingly, needle gauge had no significant effect on pneumothorax frequency, but due to the small sample size, non-randomisation, and bias in needle size selection as per lesion size, further studies are required to fully elucidate the causal relationship between needle size and post-procedural pneumothorax rate. The needle should be as perpendicular as possible to the pleura (needle-pleural angle close to 90°), to minimise the possibility of pneumothorax after percutaneous transthoracic needle biopsy.

A comparison of imaging guided double percutaneous aspiration injection and surgery in the treatment of cystic echinococcosis of liver.

OBJECTIVE: To compare the results and complications of treatment by double percutaneous aspiration injection (DPAI) in cystic echinococcosis (CE) of the liver with those of surgery. To the best of our knowledge, such a study has not been carried out till date. METHODS: From November 2012 to November 2015, 43 patients were randomly allocated to DPAI group (n = 22) and surgery group (n = 21). After the intervention, patients were evaluated monthly for 3 months, then at the sixth month and 6 monthly thereafter. RESULTS: Average hospital stay was 2.38 days in DPAI group and 8.23 days in the surgery group. Response to DPAI was categorized as successful in 95.3% (n = 20) patients and incomplete in 4.7% (n = 1) patients. Response to surgery was characterized as successful in 85.7% (n = 18) patients and incomplete in 4.7% (n = 1) patients, and recurrence was seen in 9.5% (n = 2) patients. Using a 10% margin for non-inferiority, treatment response in the DPAI group was non-inferior to that of the surgery group. In the DPAI group, 19 patients had no complications, minor complications were seen in 4.7% (n = 1) patients and a major complication was seen in 4.7% (n = 1) patients. In the surgery group, no complications were seen in 13 patients, major complications were seen in 28.57% (n = 6) patients and minor complications were seen in 9.5% (n = 2) patients. CONCLUSION: Over a follow-up period of 3 years, DPAI is non-inferior to surgery in the treatment of CE of the liver, while there is a statistically significant difference in the hospital stay and occurrence of complications. Advances in knowledge: DPAI offers advantages such as a short hospital stay, minimal invasiveness and morbidity, while being non-inferior to surgery. Total Immunoglobulin G antibody titres have limited utility in follow-up of patients treated.

Profile of leptin, adiponectin, and body fat in patients with hyperprolactinemia: Response to treatment with cabergoline.

INTRODUCTION: Though hypoadiponectinemia and leptin resistance have been proposed as potential factors for weight gain in patients with hyperprolactinemia (HPL), the effects of HPL and cabergoline on these adipocyte-derived hormones are not clear. Aims of this study were (i) to assess the alterations of body fat, leptin, and adiponectin in patients with HPL (ii) effect of cabergoline treatment on these parameters. METHODS: Nineteen consecutive patients with prolactinoma (median prolactin [PRL] 118.6 (interquartile range: 105.3) µg/L) and 20 controls were studied in a nonrandomized matched prospective design. The controls were age, gender, and body mass index (BMI) matched. Anthropometric data, metabolic variables, leptin, and adiponectin were studied at baseline and 3 and 6 months after cabergoline treatment. RESULTS: Patients with prolactinoma had increased level of fasting plasma glucose (P < 0.001) as compared to age-, gender-, and BMI-matched healthy controls. Estradiol concentration of controls was higher than that of patients (P = 0.018). Patients with prolactinoma had higher levels of leptin (P = 0.027) as compared to healthy controls without a significant difference in adiponectin levels. There was a significant decrease of body weight at 3 months (P = 0.029), with a further decline at 6 months (P < 0.001) of cabergoline therapy. Furthermore, there was a significant decrement of BMI (P < 0.001), waist circumference (P = 0.003), waist-hip ratio (P = 0.03), total body fat (P = 0.003), plasma glucose (P < 0.001), leptin levels (P = 0.013), and an increase in estradiol concentration (P = 0.03) at 6 months of cabergoline treatment. CONCLUSION: Patients with prolactinoma have adverse metabolic profile compared to matched controls. Normalization of PRL with cabergoline corrects all the metabolic abnormalities.

Low molecular weight heparin in prophylaxis of deep vein thrombosis in Asian general surgical patients: A Kashmir experience.

BACKGROUND AND OBJECTIVES: Deep vein thrombosis (DVT) occurs at a lower rate in Asia than in the rest of the world. We wanted to study the significance and efficacy of low molecular weight heparin (LMWH) in prophylaxis of DVT in major general surgical patients in the Kashmir Valley (India, Asia) so as to make it a routine in our patients. PATIENTS AND METHODS: This was a prospective study in which the effect of LMWH was compared with no prophylaxis. RESULTS: LMWHs are more effective than no prophylaxis in the prevention of DVT and pulmonary thromboembolism in highest-risk general surgical patients (odds ratio = 16.64; 95% confidence interval = 3.63-1130.03; P-value = 0.014). CONCLUSION: LMWHs have a significant prophylactic effect on DVT in general surgical patients, with a higher benefit to risk ratio, and, in spite of the low incidence of DVT in Asia, its prophylaxis should routinely be considered in this part of the world as well, preferably in the form of LMWHs.

Hemobilia in a child due to right hepatic artery pseudoaneurysm: multidetector-row computed tomography demonstration.

We present a case of a 12-year-old boy who developed upper gastrointestinal bleeding in the form of hematemesis and melena 1 month after blunt trauma to liver. Computed tomography (CT) angiography with multidetector-row CT demonstrated pseudoaneurysm of right hepatic artery related to old liver laceration to be the cause of the bleeding. Pseudoaneurysm was resected using the roadmap provided by CT angiography findings.

Computed tomography findings in bilateral perinephric lymphangiomatosis.

Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis.

64-slice CT imaging in a case of total anomalous pulmonary venous circulation.

For long, catheter angiography has been the investigation of choice for the diagnosis of congenital anomalies of the heart such as total anomalous pulmonary venous circulation (TAPVC). In the last few years, MRI and multislice CT scan have also been introduced for this purpose. We report a case where 64-slice CT scan was found very useful in the evaluation of TAPVC.

Primary mediastinal hydatid disease leading to popliteal artery hydatid cyst embolization.

Hydatid disease is a zoonosis caused by Echinococcus granulosus . Infected dogs release eggs through their feces and the eggs infect humans through food and water. The most common locations of hydatid cysts are the liver and lungs, but primary mediastinal involvement, though rare, can be encountered. We report on a 16-year-old female with a primary mediastinal hydatid cyst leading to popliteal arterial embolization. The mediastinal lesion was treated with partial pericystectomy with removal of the germinal membrane and prophylactic albendazole. In endemic areas, it is important to consider hydatid cysts in the differential diagnosis of an acute arterial occlusion.

Uncomplicated spontaneous rupture of the pancreatic pseudocyst into the gut--CT documentation: a series of two cases.

Spontaneous rupture of the pancreatic pseudocyst into the surrounding hollow viscera is rare and, may be associated with life-threatening bleeding. Such cases require emergency surgical intervention. Uncomplicated rupture of pseudocyst is an even rarer occurrence. We present herein two cases of uncomplicated spontaneous rupture of a pancreatic pseudocyst into the stomach with complete resolution.

CT findings in obturator hernia with Meckel's diverticulum--a case report.

Obturator hernia is rare, constituting <2% of all abdominal hernias. Clinical diagnosis is rarely made due to vague signs and symptoms. Delayed diagnosis markedly increases postoperative morbidity and mortality especially because the affected patients are often old with other comorbid conditions. Pelvic CT is almost 100% accurate in the diagnosis of obturator hernia and should be the modality of choice in older patients presenting with intestinal obstruction of unknown etiology.
