Quality of gastroenterology research published in Saudi Arabian scientific journals.

BACKGROUND/AIMS: Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. PATIENTS AND METHODS: An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. RESULTS: A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1 st 5-year period (2003-2007) to 330 in the 2 nd period (2008-2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. CONCLUSION: In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals.

Post-bariatric surgery satisfaction and body-contouring consideration after massive weight loss.

BACKGROUND: Following a bariatric surgery and massive weight-loss, the outcome is usually sullied by consequences on the body's contour and redundant skin. AIMS: We aimed to record the frequency of contour irregularities and quantify patients' satisfaction with appearance and anticipations from body contouring surgery. MATERIALS AND METHODS: The ethical committee at King Abdulaziz University Hospital approved the study, and patients were consented. A cross-sectional study targeting the post-bariatric patients from May 2011 to April 2012 was conducted at our hospital. We used post-massive weight loss Satisfaction Questionnaire. RESULTS: The total numbers of patients were 64 (51 women and 13 men), of which 57 patients (89.2%) developed sagging skin. Most patients were dissatisfied with their appearance after weight loss. The most common zones were the upper arms (50%) and abdomen (45%). Considerably more women (36.2%) than men (24%) were dissatisfied with certain body areas. The most noticeable expectation of patients from body contouring surgery was improved cosmetic appearance (65.6%) and self-confidence (64.1%). More women (70.58%) than men (46.15%) expected a better cosmetic appearance after body contouring (P = 0.003). CONCLUSION: After bariatric surgery, sagging excess skin is an unsatisfactory problem. Therefore, body contouring surgery must be included in morbid obesity management.
