ObjectiveTo evaluate the short-term outcomes for laparoscopic Rouxen-Y gastric bypass in 275 patients with a follow-up of 1 to 31 months. Summary Background DataThe Roux-en-Y gastric bypass is a highly successful approach to morbid obesity but results in significant perioperative complications. A laparoscopic approach has significant potential to reduce perioperative complications and recovery time. MethodsConsecutive patients (n ϭ 275) who met NIH criteria for bariatric surgery were offered laparoscopic Roux-en-Y gastric bypass between July 1997 and March 2000. A 15-mL gastric pouch and a 75-cm Roux limb (150 cm for superobese) was created using five or six trocar incisions. ResultsThe conversion rate to open gastric bypass was 1%. The start of an oral diet began a mean of 1.58 days after surgery, with a median hospital stay of 2 days and return to work at 21 days. The incidence of early major and minor complications was 3.3% and 27%, respectively. One death occurred related to a pulmonary embolus (0.4%). The hernia rate was 0.7%, and wound infections requiring outpatient drainage only were uncommon (5%). Excess weight loss at 24 and 30 months was 83% and 77%, respectively. In patients with more than 1 year of follow-up, most of the comorbidities were improved or resolved, and 95% reported significant improvement in quality of life. ConclusionLaparoscopic Roux-en-Y gastric bypass is effective in achieving weight loss and in improving comorbidities and quality of life while reducing recovery time and perioperative complications.Roux-en-Y gastric bypass (RYGBP) has been shown to produce significant weight loss in patients with clinically severe obesity: most studies report a weight loss of 60% to 70% of excess body weight.
LRYGBP resulted in significant weight loss (60% percent of excess body weight loss) and resolution (83%) of T2DM. Patients with the shortest duration and mildest form of T2DM had a higher rate of T2DM resolution after surgery, suggesting that early surgical intervention is warranted to increase the likelihood of rendering patients euglycemic.
The staging concept of LSG followed by LRYGBP is a safe and effective surgical approach for high-risk patients seeking bariatric surgery.
Objective: To evaluate pre-and postoperative clinical parameters associated with improvement of diabetes up to 4 years after laparoscopic Roux-en-Y gastric bypass (LRYGBP) in patients with type 2 diabetes mellitus (T2DM). Summary Background Data: The surgical treatment of morbid obesity leads to dramatic improvement in the comorbidity status of most patients with T2DM. However, little is known concerning what preoperative clinical factors are associated with postoperative longterm improvement in diabetes in the morbidly obese patient with diabetes. Methods: We evaluated pre-and postoperative data, including demographics, duration of diabetes, metabolic parameters, and clinical outcomes, in all patients with impaired fasting glucose (IFG) and type T2DM undergoing LRYGBP from July 1997 to May 2002. Results: During this 5-year period, 1160 patients underwent LRYGBP and 240 (21%) had IFG or T2DM. Follow up was possible in 191 of 240 patients (80%). There were 144 females (75%) with a mean preoperative age of 48 years (range, 26-67 years). After surgery, weight and body mass index decreased from 308 lbs and 50.1 kg/m 2 to 211 lbs and 34 kg/m 2 for a mean weight loss of 97 lbs and mean excess weight loss of 60%. Fasting plasma glucose and glycosylated hemoglobin concentrations returned to normal levels (83%) or markedly improved (17%) in all patients. A significant reduction in use of oral antidiabetic agents (80%) and insulin (79%) followed surgical treatment. Patients with the shortest duration (Ͻ5 years), the mildest form of T2DM (diet controlled), and the greatest weight loss after surgery were most likely to achieve complete resolution of T2DM. Conclusion: LRYGBP resulted in significant weight loss (60% percent of excess body weight loss) and resolution (83%) of T2DM. Patients with the shortest duration and mildest form of T2DM had a higher rate of T2DM resolution after surgery, suggesting that early surgical intervention is warranted to increase the likelihood of rendering patients euglycemic.
Surgical weight loss results in significant improvement of liver morphology in severely obese patients. These beneficial changes may be associated with a significant reduction in the prevalence of the metabolic syndrome.
Background: Morbid obesity (MO) is a risk factor for congestive heart failure (CHF). The presence of MO impairs functional status and disqualifies patients for cardiac transplantation. Bariatric surgery (BAS) is a frontline, durable treatment for MO; however, the safety and efficacy of BAS in advanced CHF is unknown. Hypothesis: We hypothesized that by utilizing a coordinated approach between an experienced surgical team and heart failure specialists, BAS is safe in patients with advanced systolic CHF and results in favorable outcomes. Methods: We performed a retrospective chart review of 12 patients with MO (body mass index [BMI] 53±7 kg/m 2 ) and systolic CHF (left ventricular ejection fraction [LVEF] 22±7%, New York Heart Association [NYHA] class 2.9±0.7) who underwent BAS, and then compared outcomes with 10 matched controls (BMI 47.2±3.6 kg/m 2 , LVEF 24±7%, and NYHA class 2.4±0.7) who were given diet and exercise counseling. Results: At 1 y, hospital readmission in BAS patients was significantly lower than controls (0.4±0.8 versus 2.5±2.6, p = 0.04); LVEF improved significantly in BAS patients (35±15%, p = 0.005), but not in controls (29±14%, p = not significant [NS]). The NYHA class improved in BAS patients (2.3±0.5, p = 0.02), but deteriorated in controls (3.3±0.9, p = 0.02). One BAS patient was successfully transplanted, and another listed for transplantation. Conclusions: Bariatric surgery is safe and effective in patients with MO and severe systolic CHF, and should be considered in patients who have failed conventional therapy to improve clinical status.
Purpose Mortality following bariatric surgery is a rare event in contemporary series, making it difficult for any single center to draw meaningful conclusions as to cause of death. Nevertheless, much of the published mortality data come from single center case series and reviews of administrative databases. These sources tend to produce lower mortality estimates than those obtained from controlled clinical trials. Furthermore, information about the causes of death and how they were determined is not always available. The aim of the present report is to describe in detail all deaths occurring within 30-days of surgery in the Longitudinal Assessment of Bariatric Surgery (LABS). Methods LABS is a 10-center observational cohort study of bariatric surgical outcomes. Data were collected prospectively for bariatric surgeries performed between March 2005 and April 2009. All deaths occurring within 30-days of surgery were identified, and cause of death assigned by an independent Adjudication Subcommittee, blinded to operating surgeon and site. Results 6118 patients underwent primary bariatric surgery. 18 deaths (0.3%) occurred within 30-days of surgery. The most common cause of death was sepsis (33% of deaths), followed by cardiac causes (28%) and pulmonary embolism (17%). For one patient cause of death could not be determined despite examination of all available information. Conclusions This study confirms the low 30-day mortality rate following bariatric surgery. The recognized complications of anastomotic leak, cardiac events, and pulmonary emboli accounted for the majority of 30-day deaths.
