Length of Barrett’s segment predicts success of extensive endomucosal resection for eradication of Barrett’s esophagus with early neoplasia

Background  

Although the efficacy and safety of extensive endomucosal resection (EMR) in eradicating Barrett’s esophagus (BE) harbouring early neoplasia have been established, factors predicting efficacy remains unclear.     

Prevalence of early stages of chronic kidney disease in healthy army personnel

Introduction: Chronic kidney disease (CKD) is associated with significant morbidity and mortality. Screening and detection of early stages of CKD can help institute interventions that may delay the progression of the disease. One aim was to study the prevalence of early stages of CKD in the Army.Methods: A cross-sectional study ofArmy Personnel in an Army cantt in Central India was carried out. All participants filled a structured questionnaire and anthropometric data was collected. Investigative profile included routine urine exam, semi-quantitative microalbuminuria (MAU), serum creatinine, lipid profile and fasting blood glucose. Glomerular Filteration rate (eGFR) was calculated using the Modification of Diet in Renal Diseases (MDRD) study equation.Result: A total of 1920 subjects were examined with 731 (38.07%) from Arms and 1189 (6I.93%) from Services. 348 were excluded and of the remaining 1572 subjects, 141 (8.97%) had MAU and 157 (9.99%) had deranged Albumin Creatinine Ratio (ACR). Mean eGFR by MDRD equation was 102 ± 25.84 ml/min/1.73m². Early CKD was seen in 150 (9.54%) with 84 (5.34%) in stage I CKD, 55 (3.5%) in stage II and 11 (0.7%) in stage III. Multiple logistic regression showed BMI > 23, the presence of DM and HTN were independent risk factors for CKD.Conclusion: 9.54 % of healthy army personnel were found to have early stages of CKD. Institution of screening programs can result in early detection of CKD.     

EXPERIENCE WITH VIPERINE ENVENOMATION

Two hundred and twenty one cases of viperine envenomation, who presented to hospital without specific treatment, seen over an twenty five years period, have been presented. Mild, moderate and severe envenomation was encountered in 33 per cent, 47 per cent and 20 per cent respectively. Bites on feet and ankles were seen in 85.5 per cent of cases. The average time interval between bite and hospitalisation was 4.8 hours, range being 15 minutes to 7 days. Local swelling was observed in 97.7 per cent, hematuria in 62 per cent, mucosal haemorrhages in 24.8 per cent and haematemesis in 19 per cent of patients. Average Antisnake Venom (ASV) required in mild, moderate and severe envenomation was 50 ml, 147.5 ml and 324 ml respectively. Major complications observed were renal failure in 10, intracompartmental syndrome in 3, intracerebral bleed and septicaemia in 2 each. One patient each developed finger gangrene, osteomyelitis, perirenal haematoma, sinus bradycardia and uncontrolled bleeding. Blood transfusion was required in 32 patients. Reactions to ASV were seen in 12 patients and overall there were 5 deaths.KEY WORDS: Antisnake venom, Viperine envenomation     

'Short' double-balloon enteroscope endoscopic retrograde cholangiopancreatography in patients with a surgically altered upper gastrointestinal tract

BACKGROUND:

Endoscopic retrograde cholangiopancreatography (ERCP) remains a challenge for endoscopists in patients with surgically altered anatomy of the upper gastrointestinal tract. Double-balloon enteroscopes (DBEs) have revolutionized the ability to access the small bowel. The indication for its therapeutic use is expanding to include ERCP for patients who have undergone small bowel reconstruction. Most of the published experiences in DBE-assisted ERCP have used conventional double-balloon enteroscopes that are 200 cm in length, which do not permit use of the standard ERCP accessories. The authors report their experience with DBE-assisted ERCP using a ‘short’ DBE in patients with surgically altered anatomy.

METHODS:

A retrospective review of patients with previous small bowel reconstruction who underwent ERCP with a ‘short’ DBE at the Centre for Therapeutic Endoscopy and Endoscopic Oncology (Toronto, Ontario) between February 2007 and November 2008 was performed.

RESULTS:

A total of 20 patients (10 men) with a mean age of 57.9 years (range 26 to 85 years) underwent 29 sessions of ERCP with a DBE. Six patients underwent Billroth II gastroenterostomy, seven patients Roux-en-Y hepaticojejunostomy, five patients Roux-en-Y gastrojejunostomy, one patient Roux-en-Y esophagojejunostomy and one patient a Whipple’s operation with choledochojejunostomy. Some patients (n=12 [60%]) underwent previous attempts at ERCP in which the papilla of Vater or bilioenteric anastomosis could not be reached with either a duodenoscope or pediatric colonoscope. All procedures were performed with a commercially available DBE (working length 152 cm, distal end diameter 9.4 mm, channel diameter 2.8 mm). The procedures were performed under conscious sedation with intravenous midazolam, fentanyl and diazepam, except in one patient in whom general anesthesia was administered. Either the papilla of Vater or bilioenteric anastomosis was reached in 25 of 29 cases (86.2%) in a mean duration of 20.8 min (range 5 min to 82 min). Bile duct cannulation was successful in 24 of 25 cases in which the papilla or bilioenteric anastomosis was reached. Therapeutic interventions were successful in 15 patients (24 procedures) including sphincterotomy (n=7), stone extraction (n=9), biliary dilation (n=8), stent placement (n=9) and stent removal (n=8). The mean total duration of the procedures was 70.7 min (range 30 min to 117 min). There were no procedure-related complications.

CONCLUSION:

DBEs enable successful diagnostic and therapeutic ERCP in patients with a surgically altered anatomy of the upper gastrointestinal tract. It is a safe, feasible and less invasive therapeutic option in this group of patients. Standard ‘long’ DBEs have limitations of long working length and the need for modified ERCP accessories. ‘Short’ DBEs are equally as effective in reaching the target limb as standard ‘long’ DBEs, and overcomes some limitations of long DBEs to result in high success rates for endoscopic therapy.     

A SURVEY OF HOSPITAL MORBIDITY,MORTALITY AND QUALITY OF LIFE FOLLOWING CORONARY ARTERY BYPASS SURGERY IN A UK INDO-ASIAN POPULATION

To survey the in-hospital morbidity, mortality, length of stay in the intensive therapy unit (ITU) and hospital and quality of life in patients of Indo-Asian origin following coronary artery bypass (CABG) surgery, 345 consecutive patients (mean age 58 years; SD 8.9; range 32-88 years) undergoing primary, isolated CABG were studied. Non-elective CABG was undertaken in 41% of patients. The left anterior descending artery (LAD) was grafted in 89%, although in 30% of these the internal mammary artery (IMA) was not used. Following CABG, the hospital morbidity and mortality was within the expected range, although there was a trend towards higher in-hospital mortality in the Parsonnet low risk group of patients. The length of ITU and hospital stay was not prolonged. Using the SF-36 questionnaire in postoperative patients, low quality of life scores were obtained for six of the eight modalities tested including physical functioning, bodily pain and general health perception. The low quality of life scores and IMA usage in Indo-Asians needs to be addressed.
