Currie A, Chetwood A, Ahmed AR, 2011, Bariatric surgery and renal function, Obes Surg, Vol: 21, Pages: 528-539, ISSN: 1708-0428
Obesity causes a significant healthcare burden and has been shown to be an important risk factor in the development of cardiovascular disease, type 2 diabetes, and increasingly chronic kidney disease. Bariatric surgery is the most effective treatment for obesity and has been shown to drastically improve both blood pressure and diabetic control. However, the interaction of bariatric surgery and renal function is less clear. This review focuses on the effect of bariatric surgery on renal function both in the acute situation, with respect to acute kidney injury, and also on changes in renal function parameters post-bariatric surgery weight loss. The interaction of obesity, bariatric surgery, and nephrolithiasis as a precipitant of acute kidney injury will also be considered. The role of bariatric surgery in pre- and post-renal transplant recipients is discussed as well as possible mechanisms underlying the improvement in renal function.

Ahmed AR, Rickards G, Johnson J, et al., 2009, Radiological findings in symptomatic internal hernias after laparoscopic gastric bypass., Obes Surg, Vol: 19, Pages: 1530-1535
BACKGROUND: Internal hernias (IHs) can complicate laparoscopic Roux-en-Y gastric bypass (LRYGB). A number of radiological investigations can be used in the diagnosis. These include plain X-rays, upper gastrointestinal (UGI) series, ultrasound, and computed tomography (CT) scanning. We present radiological findings in our series of 58 symptomatic internal hernias based on our 6-year experience (2000-2006) of 2,572 LRYGB patients. METHODS: A retrospective chart review was performed of all patients undergoing LRYGB who developed symptomatic internal hernia requiring operative intervention between January 1, 2000 and September 15, 2006. Types of radiological tests performed and their results were recorded. RESULTS: Fifty-eight symptomatic internal hernias were recorded, of which 56/58 (97%) underwent radiological investigation; 2/58 went directly to surgery. Of the 56 patients who underwent diagnostic imaging, 41 plain abdominal X-rays, 37 CT scans, 26 UGI series, and eight ultrasound scans were performed. Sixty-five percent of UGI series and 92% of CT scans had positive features diagnostic of internal hernia. Performing both CT and UGI series successfully diagnosed IH in 100% of cases. Subgroup analysis did not reveal any association between positive result of imaging test and type of internal hernia. CONCLUSION: CT scanning is the single most effective radiological investigation for diagnosing internal hernias post-LRYGB. In non-diagnostic cases, the addition of an upper GI series increases the diagnostic rate to 100%.

Ahmed AR, Rickards G, Coniglio D, et al., 2009, Laparoscopic Roux-en-Y gastric bypass and its early effect on blood pressure., Obes Surg, Vol: 19, Pages: 845-849, ISSN: 0960-8923
BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is known to have a significant effect on obesity-related comorbidities such as hypertension curing it in some (50-70%) while improving control in others. Our aim was to observe the changes in blood pressure (BP) in a cohort of 100 patients followed prospectively for 1 year after LRYGB. METHODS: BP measurements were recorded prospectively in 100 consecutive patients preoperatively and then postoperatively at weeks 1, 5, 9, and months 6 and 12. In order to reduce bias, three BP measurements were made by the same nurse at each office visit and the mean recorded. Pre- and postoperative usage of antihypertensive medication was also noted. RESULTS: Eighty-nine women and 11 men underwent LRYGB and their BP monitored for 1 year. There was an 85% follow-up rate with mean % excess body weight loss of 60. Reductions in systolic (9 mmHg) and diastolic (7 mmHg) BP measurements were seen as early as week 1 postoperatively and maintained for the duration of the observation period (P < 0.05). Furthermore, postoperative usage of antihypertensive medication is reduced to a third of preoperative use. CONCLUSION: LRYGB is associated with an early reduction in BP and antihypertensive medication usage which is maintained at 1 year after surgery. This early impact on blood pressure occurs before any significant weight loss is achieved thereby suggesting a hormonal mechanism that may be involved for the changes observed.
