Bariatric Times • June 2008 Journal Watch Then, after having achieved significant weight loss and reduction in comorbidities, underwent laparoscopic Roux-en-Y gastric bypass. The results are discussed, and authors conclude that this two-stage method is safe and effective for high-risk patients seeking bariatric surgery. PMID: 16738970 Laparoscopic sleeve gastrectomy (LSG): Review of a new bariatric procedure and initial results. Mognol P, Chosidow D, Marmuse JP. Surg Technol Int 2006;15:47–52. Review. Synopsis: To evaluate the outcomes and initial results of laparoscopic sleeve gastrectomy, the authors conducted a literature review and performed a retrospective analysis of operative time, complication rates, hospital length of stay, and percentage of excess body weight loss for the initial 10 patients (5 female) who underwent this procedure. Based on the results, they conclude that this procedure can be integrated safely into a bariatric treatment program as a one-step restrictive procedure if long-term results are good or as a first-step procedure before gastric bypass or duodenal switch. PMID: 17029161 A prospective multicenter study of 163 sleeve gastrectomies: Results at 1 and 2 years. Nocca D, Krawczykowsky D, Bomans B, et al. Obes Surg Epub ahead of print 2008 Mar 4. Synopsis: To evaluate the effectiveness and feasibility of laparoscopic sleeve gastrectomy as a restrictive procedure, researchers conducted a multicenter prospective study of 163 morbidly (n=84), severely (n=35), or super (n=44) obese patients (68% female) with high-volume eating disorders and severe comorbidities such as diabetes, sleep apnea, and hypertension. Based on the results, authors conclude that laparoscopic sleeve gastrectomy may be proposed for volume-eater patients or to prepare superobese patients for laparoscopic gastric bypass or laparoscopic duodenal switch, but that long-term outcomes remain to be evaluated. PMID: 18317859 Indications for sleeve gastrectomy as a primary procedure for weight loss in the morbidly obese. Tucker ON, Szomstein S, Rosenthal RJ. J Gastrointest Surg 2008;12(4):662–7. Epub 2008 Feb 9. Synopsis: To evaluate single-stage laparoscopic sleeve gastrectomy as a surgical option for morbid obesity, researchers retrospectively reviewed 148 cases in which this technique was performed as a onestage primary restrictive procedure from November 2004 to April 2007. Based on the results, authors conclude that laparoscopic sleeve gastrectomy has acceptable operative time, intraoperative blood loss, and perioperative complication rate, and represents a safe option for weight loss in the morbidly obese. PMID: 18264685 CARDIOVASCULAR RISK FACTORS AND ISSUES Systemic inflammation and cardiovascular risk factors: Are morbidly obese subjects different? Faintuch J, Marques PC, Bortolotto LA, et al. Obes Surg Epub ahead of print 2008 Apr 3. Synopsis: To analyze correlation among variables related to systemic inflammation and cardiovascular risk factors, specifically inflammatory markers, pulse-wave velocity, and intima-media thickness, researchers conducted a prospective study of 29 morbidly obese patients (82.8% female), all of whom were clinically stable candidates for elective bariatric operation. Based on the results, authors conclude that a unique interaction exists between adiposity, inflammation, and cardiovascular risk in seriously obese subjects. PMID: 18392896 Reversibility of cardiac abnormalities in morbidly obese adolescents. Ippisch HM, Inge TH, Daniels SR, et al. J Am Coll Cardiol 2008;51(14): 1342–8. Synopsis: To evaluate changes in cardiac geometry and function before and after weight loss in morbidly obese adolescents, left ventricular mass, left ventricular geometry, and systolic and diastolic function were assessed in 38 adolescents (29 female) before and after they underwent bariatric surgery (mean follow up 10 +/- 3 months). Based on the findings that elevated left ventricular mass index, concentric left ventricular hypertrophy, altered diastolic function, and cardiac workload significantly improved following surgically induced weight loss, the authors conclude that large weight loss due to bariatric surgery improves predictors of future cardiovascular morbidity in adolescents. PMID: 18387434 Improvement in dilated cardiomyopathy after bariatric surgery. Ristow B, Rabkin J, Haeusslein E. J Card Fail 2008;14(3):198–202. Synopsis: The authors report on two cases of patients with severe systolic dysfunction and Class IV heart failure who were referred for bariatric surgery in order to achieve enough weight loss to then be considered for cardiac transplantation. It was found that after undergoing laparoscopic vertical gastrectomy and losing 46 to 52 kg, both individuals exhibited enough cardiac improvement two years post-surgery that they are no longer listed for transplant. PMID: 18381182 Shrinking cardiovascular risk through bariatric surgery: Application of Framingham risk score in gastric bypass. Kligman MD, Dexter DJ, Omer S, Park AE. Surgery 2008;143(4):533–8. Epub 2008 Jan 30. Synopsis: Researchers conducted a retrospective analysis of 101 consecutive patients who underwent laparoscopic Roux-en-Y gastric bypass to evaluate the effect of this procedure on the prevalence of coronary heart disease risk factors and also used the Framingham risk score to estimate postoperative reduction in 10-year coronary heart disease risk. Based on the results, authors conclude that gastric bypass surgery reduces 10-year coronary risk by more than half. PMID: 18374051 Metabolic syndrome phenotype in very obese women. Chang C, Garcia-Garcia AB, Hamilton E, et al. Metab Syndr Relat Disord 2007;5(1):3–12. Synopsis: To determine the pattern of metabolic risk factors in very obese women considered candidates for bariatric surgery, 28 women of this type (11 with type 2 diabetes; 26 met criteria for metabolic syndrome) were compared to 28 nonobese women. Based on the results, authors conclude that the metabolic syndrome apparently typical of very obese women is characterized by insulin resistance, glucose intolerance, and a proinflammatory state, and that this pattern is more likely to lead to type 2 diabetes prior to development of clinically evident cardiovascular disease. PMID: 18370809 of print 2008 Mar 27. Synopsis: To establish normative data on suspected psychosurgical risk factors for bariatric surgery (i.e., to determine if males and females differ in these factors), researchers analyzed the results of a psychological test and a depression inventory administered to 361 consecutive bariatric surgery candidates. Among the findings are that males have significantly higher BMIs, but females have tried significantly more diets and are significantly more likely to report histories of depression and anxiety. Authors conclude that males and females differ significantly on suspected psychosurgical risk factors and recommend that assessments of bariatric surgery candidates recognize that males and females have different baselines for such factors. PMID: 18368463 Gender comparisons in psychological characteristics of obese binge eaters. Jirik-Babb P, Norring C. Eat Weight Disord 2005;10(4):e101–4. Synopsis: Researchers investigated differences in levels of depression, anxiety, and self-esteem between genders and between obese binge eaters versus obese nonbinge eaters by evaluating 48 female (26 binge eaters and 22 nonbinge eaters) and 13 male (4 binge eaters and 9 nonbinge eaters) outpatients in a hospital weight-loss program. It was found that the females had higher levels of depression compared to the males, and in both genders, the binge eaters had higher levels of depression and anxiety and lower levels of self-esteem than the nonbinge eaters. PMID: 16682863 Gender and binge eating among bariatric surgery candidates. Mazzeo SE, Saunders R, Mitchell KS. Eat Behav 2006;7(1):47–52. Epub 2005 Jun 13. Synopsis: Researchers examined gender differences and their correlates within a sample of 487 patients presenting for bariatric surgery. They found that women were more depressed, dieted more, and were more likely to report that their weight interfered with feeling good about themselves. They also found that among women, both depression and self-esteem were associated with binge-eating symptomatology, while among men only depression contributed to binge-eating scores.
