AIM:To investigate all patients referred to our center with non-responsive celiac disease (NRCD),to establish a cause for their continued symptoms.METHODS:We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period.These individuals were investigated to establish the eitiology of their continued symptoms.The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement.They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion.A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible.Colonoscopy,lactulose hydrogen breath testing,pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted.Their clinical progress was followed over a minimum of 2 years.RESULTS:One hundred and twelve consecutive patients were referred with NRCD.Twelve were found not to have celiac disease (CD).Of the remaining 100 patients,45% were not adequately adhering to a strict gluten-free diet,with 24 (53%) found to be inadvertently ingesting gluten,and 21 (47%) admitting noncompliance.Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%.Refractory CD was diagnosed in 9%.Three of these were diagnosed with intestinal lymphoma.After 2 years,78 patients remained well,eight had continuing symptoms,and four had died.CONCLUSION:In individuals with NRCD,a remediable cause can be found in 90%:with continued gluten ingestion as the leading cause.We propose an algorithm for investigation. 展开更多

AIM:To evaluate the safety and feasibility of biliary tract reoperation by laparoscopy for the patients with retained or recurrent stones who failed in endoscopic sphincterotomy. METHODS:A retrospective analysis of data obtained from attempted laparoscopic reoperation for 39 patients in a single institution was performed, examining open conversion rates, operative times, complications, and hospital stay. RESULTS:Out of the 39 cases, 38 (97%) completed laparoscopy, 1 required conversion to open operation because of difficulty in exposing the common bile duct. The mean operative time was 135 min. The mean post-operative hospital stay was 4 d. Procedures included laparoscopic residual gallbladder resection in 3 cases, laparoscopic common bile duct exploration and primary duct closure at choledochotomy in 13 cases, and laparoscopic common bile duct exploration and choledochotomy with T tube drainage in 22 cases. Duodenal perforation occurred in 1 case during dissection and was repaired laparoscopically. Retained stones were found in 2 cases. Postoperative asymptomatic hyperamlasemia occurred in 3 cases. There were no complications due to port placement, postoperative bleeding, bile or bowel leakage and mortality. No recurrence or formation of duct stricture was observed during a mean follow-up period of 18 mo. CONCLUSION:Laparoscopic biliary tract reoperation is safe and feasible if it is performed by experiencedlaparoscopic surgeons, and is an alternative choice for patients with choledocholithiasis who fail in endoscopic sphincterectomy. 展开更多

Objectives:This study aimed to evaluate the effectiveness of slow deep breathing relaxation exercise(SDBRE)in reducing patients’pain levels during chest tube removal(CTR)post coronary artery bypass grafting(CABG)surgery.Methods:In 2019,fifty post-CABG patients were conveniently selected from a cardiac intensive care unit in Jordan’s major referral heart institute.The patients were randomly assigned to either an intervention group or a control group.A total of 25 patients were assigned into the experimental group who received slow deep breathing relaxation Exercise(SDBRE)alongside the conventional care before CTR.The remaining 25 patients constituted the control group(50%)that had CTR following conventional care.The Visual Analogue Scale(VAS)was used to measure the participants’pain levels during three phases:before CTR(Time 1),5-min post CTR(Time 2),and 15-min post CTR(Time 2)to compare the intervention effect between the two groups.Results:The data analysis findings for the control and intervention group of patients showed that there was a statistically significant decline in their pain level across time for both groups(H¼32.71,P<0.01;H=47.23,P<0.01)respectively.The intervention group had significantly lower pain levels than the control group at Time 2(3.50[1.20,5.30]vs.7.90[7.00,9.00],P<0.01)and Time 3(0.00[0.00,1.30]vs.3.60[2.40,4.10]P<0.01).Conclusions:Using SDBRE during CTR is an effective technique for reducing pain which can minimize the need for analgesics and their associated adverse effects. 展开更多

Objective To examine long term efficacy of percutaneous transluminal coronary angioplasty (PTCA),coronary stenting and to assess the factors affecting its efficacy Methods A total of 790 patients who underwent successful PTCA and PTCA+stent in this hospital were followed by direct interview or letter The rate of follow up was 84 2% and the period of follow up was 0 9-12 7 (3 5±2 4) years Results During follow up, 4 (0 5%) patients died, 22 (2 8%) had nonfatal acute myocardial infarction, 10 (1 3%) had coronary artery bypass surgery, and 98 (12 4%) had repeat PTCA The rate of recurrent angina pectoris was 31 1% The cardiac event free survival rate calculated by the Kaplan Meier method was 88 2% at 1 year and 80 6% at 12 7 years Cox regression analysis showed that there was a positive correlation between AMI history, stent implantation and the risk of cardiac events, and there was a negative correlation between the number of diseased arteries and the risk of cardiac events Compared to the PTCA group, patients with PTCA+stent had significantly lower rates of total cardiac events Conclusion The long term efficacy of PTCA, especially PTCA + stent in Chinese patients was very satisfactory, suggesting that PTCA+stent therapy should be the major treatment for revascularization in patients with coronary heart disease 展开更多
