Obesity: An Independent Predictor of Morbidity and Graft Loss after Kidney Transplantation.

BACKGROUND: There is conflicting information on current medical and surgical complications associated with high body mass index (BMI) after kidney transplantation. METHODS: In a single-center observational study, we analyzed the 5-year outcomes of all consecutive primary kidney transplant recipients between 2010 and 2015 based on BMI at the time of transplant. RESULTS: There were 1,467 patients included in this study, distributed in the following groups based on BMI: underweight (n = 32, 2.2%), normal (n = 407, 27.7%), overweight (n = 477, 32.5%), grade I obesity (n = 387, 26.4%), grade II obesity (n = 155, 10.6%), and grade III obesity (n = 9, 0.6%). Obesity was associated with an increased incidence of delayed graft function (p = 0.008), length of stay (LOS, p = 0.03), 30-day surgical re-exploration (p = 0.02), and hospital readmission (p < 0.0001). Obesity was also associated with higher 1-year serum creatinine (p = 0.03) and increased 5-year incidence of cardiac events (p < 0.0001) and congestive heart failure (p < 0.0001). Multivariable Cox regression analyses determined grade III obesity (HR = 5.84, 95% CI: 1.40-24.36, p = 0.01), LOS >4 days (HR = 1.94, 95% CI: 1.19-3.18, p = 0.008), hospital readmission (HR = 2.25, 95% CI: 1.20-4.22, p = 0.01), 1-year serum creatinine >1.5 (HR = 1.95, 95% CI: 1.20-3.18, p = 0.007), and proteinuria (UPC) >1 g/g (HR = 1.85, 95% CI: 1.06-3.24, p = 0.03) as independent predictors of death-censored graft failure. CONCLUSION: In the current era of renal transplant care, obesity is common, and high BMI remains associated with significant medical and surgical complications after transplant.

Laparoscopic-assisted ERCP and EUS in patients with prior Roux-en-Y gastric bypass surgery: a dual-center case series experience.

BACKGROUND: Patients with Roux-en-Y gastric bypass (RYGB) develop pancreatobiliary issues after surgery. Endoscopic management via the conventional route with endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) is quite limited due to the altered anatomy. Laparoscopic-assisted ERCP (LA-ERCP) via the excluded stomach has been highly successful. Reported use of laparoscopic-assisted EUS (LA-EUS) is extremely rare. METHODS: A retrospective review was conducted at two tertiary referral centers for cases that involved laparoscopic-assisted ERCP and EUS. Patient demographic data were collected along with data regarding procedure, indication, complications and length of stay. RESULTS: A total of 16 cases involving 15 patients were identified: 11 cases of LA-ERCP and five cases of combined LA-EUS plus LA-ERCP were performed. Four patients had previously undergone failed endoscopy via the conventional route (27 %). There was a 100 % biliary/pancreatic cannulation and intervention rate. There were no endoscopic-related complications. Therapeutic interventions included laparoscopic cholecystectomy, lysis of adhesions, biliary and pancreatic sphincterotomy, biliary and pancreatic stent placement, stone removal including mechanical lithotripsy and EUS biopsy and diagnosis of pancreatic cancer. Average discharge was on postoperative day 3.4. However, 50 % were discharged after 1 day. CONCLUSIONS: LA-ERCP and combined LA-EUS plus LA-ERCP are safe and highly successful diagnostic and therapeutic modalities for a wide variety of pancreatobiliary ailments in RYGB patients.

Diabetes remission and glycemic response to pre-bariatric surgery diet.

BACKGROUND: Before bariatric surgery, some patients with type 2 diabetes mellitus (T2DM) experience improvement in blood glucose control and reduced insulin requirements while on a preoperative low-calorie diet (LCD). We hypothesized that patients who exhibit a significant glycemic response to this diet are more likely to experience remission of their diabetes in the postoperative period. MATERIALS AND METHODS: Insulin-dependent T2DM patients undergoing bariatric surgery between August 2006 and February 2011 were eligible for inclusion. Insulin requirements at day 0 and 10 of the LCD were compared. Patients with a ≥ 50% reduction in total insulin dosage to maintain appropriate blood glucose control were considered rapid responders to the preoperative LCD. All others were non-rapid responders. We analyzed T2DM remission rates up to 1 y postoperatively. RESULTS: A total of 51 patients met inclusion criteria and 29 were categorized as rapid responders (57%). The remaining 22 were considered non-rapid responders (43%). The two groups did not differ demographically. Rapid responders had greater T2DM remission rates at 6 (44% versus 13.6%; P = 0.02) and 12 mo (72.7% versus 5.9%; P < 0.01). In patients undergoing laparoscopic gastric bypass, rapid responders showed greater excess weight loss at 3 mo (40.1% versus 28.2%; P < 0.01), 6 mo (55.2% versus 40.2%; P < 0.01), and 12 mo (67.7% versus 47.3%; P < 0.01). CONCLUSIONS: Insulin-dependent T2DM bariatric surgery patients who display a rapid glycemic response to the preoperative LCD are more likely to experience early remission of T2DM postoperatively and greater weight loss.

The impact of previous fundoplication on laparoscopic gastric bypass outcomes: a case-control evaluation.

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common comorbid condition in morbidly obese gastric bypass candidates. Unfortunately, some patients who ultimately present for bariatric surgery have previously undergone Nissen fundoplication for GERD. Many surgeons consider previous fundoplication to be a relative contraindication to subsequent laparoscopic Roux-en-Y gastric bypass (LRYGB) due to increased technical complexity and risk. We sought to compare the perioperative and long-term outcomes of a cohort of patients who had first undergone fundoplication and ultimately chose to later pursue LRYGB for morbid obesity (revision) to matched control patients. METHODS: Data were obtained from our prospectively maintained bariatric surgery database. Patients who underwent laparoscopic takedown of a previous fundoplication and conversion to LRYGB were compared to control patients who underwent primary LRYGB. For every revision patient, two control subjects were randomly selected from the database after matching for preoperative body mass index and year of surgery. RESULTS: From July 2002 to April 2011, 14 patients underwent laparoscopic takedown of a previous Nissen fundoplication and then underwent LRYGB. During the same interval, 673 patients underwent LRYGB as a primary procedure for obesity from which 28 were selected as controls. There were no conversions to open laparotomy in any patient. Subjects were similar demographically. Operating time and duration of hospital stay were significantly longer in revision patients. Complications were more frequent in revisions (36% revisions vs. 7% controls, P = 0.03). Excess weight loss 1-year after surgery was excellent in both groups and did not differ (69% revision vs. 69.6% controls, P = 0.93). CONCLUSIONS: Although associated with longer operating times, longer duration of hospital stay, and complications, LRYGB after fundoplication is feasible and safe. Long-term weight loss outcomes are similar to those seen following primary LRYGB. Previous fundoplication is not a contraindication to LRYGB.

Impact of gastrojejunostomy diameter on long-term weight loss following laparoscopic gastric bypass: a follow-up study.

BACKGROUND: Stenosis of the gastrojejunostomy after laparoscopic Roux-en-Y gastric bypass is a common occurrence. We have previously presented data demonstrating that the use of a 25-mm circular stapler results in a decreased incidence of stenosis compared to the results of a 21-mm circular stapler (6.2 vs. 15.9%, P=0.03). One potential drawback of the larger-diameter stapler is the possibility for impaired long-term weight loss due to decreased restriction. We sought to determine the impact of circular stapler diameter on excess weight loss up to 5 years after surgery. METHODS: Our initial technique for creating the gastrojejunostomy after laparoscopic gastric bypass involved the transgastric passage of a 21-mm circular stapler anvil (group 1). After a large initial experience, we switched to a 25-mm circular stapler (group 2). Follow-up data were entered prospectively into a computer database. Weight loss was recorded as percent of excess weight lost. Only patients with follow-up beyond 3 years postoperatively were eligible for inclusion. RESULTS: Group 1 consisted of 145 consecutive patients and group 2 consisted of 116 consecutive patients. There was no significant difference in weight loss between the groups at 3 (66.1 vs. 65.2%, P=0.76, n=134), 4 (66.4 vs. 58.6%, P=0.1, n=66), and 5 years after gastric bypass (62.7 vs. 57.5%, P=0.24, n=75). CONCLUSIONS: The use of a 25-mm circular stapler in laparoscopic gastric bypass operations instead of a 21-mm stapler does not result in significantly different long-term weight loss. The 25-mm stapler is preferred with our technique.

Vitamin D status of morbidly obese bariatric surgery patients.

BACKGROUND: Abnormal vitamin D levels are common in bariatric surgery patients. The incidence of deficiencies and the response to therapy is not accurately delineated. The purpose of this study was to define the vitamin D status of patients who undergo either a malabsorptive (gastric bypass) or restrictive (adjustable gastric band) bariatric surgery both prior to and after surgery. METHODS: A retrospective analysis was performed on patients to undergo bariatric surgery from July 2002 to February 2007. Serum levels of vitamin D (Vit D), parathyroid hormone (PTH), and calcium were analyzed. RESULTS: Mean patient age was 45 y; 82% of patients were women. Of 127 total patients, 84% were Vit D deficient preoperatively. These patients had a higher preoperative body mass index (BMI) than those with normal Vit D levels on initial assessment (BMI 44 versus 50 kg/m(2), P < 0.01). A correlation was found between preoperative BMI and Vit D (r(2) = 0.12, P < 0.01) and PTH levels (r(2) = 0.07, P < 0.01). One year following gastric bypass surgery, 20% of patients with elevated PTH levels had normal Vit D levels. The incidence of observed deficiencies for adjustable gastric band versus gastric bypass did not differ statistically at any interval. CONCLUSIONS: Morbidly obese patients seeking bariatric surgery are often deficient in Vit D, a fact that should be accounted for when evaluating the impact of bariatric surgery on Vit D levels. Elevated BMI and increasing degrees of obesity may be risk factors for both Vit D deficiency and secondary hyperparathyroidism. Despite normal Vit D levels, some gastric bypass patients continue to show elevated levels of PTH.

The impact of perioperative dexmedetomidine infusion on postoperative narcotic use and duration of stay after laparoscopic bariatric surgery.

Dexmedetomidine (Precedex, Hospira, Lake Forest, IL) is an alpha-2 receptor agonist with sedative and analgesic sparing properties. This medication has not been associated with respiratory suppression, despite occasionally high levels of sedation. For 10 months, all patients undergoing a laparoscopic bariatric procedure received a dexmedetomidine infusion 30 min before the anticipated completion of the procedure (n = 34). A control group was comprised of a similar number of patients to have had laparoscopic bariatric surgery in the time period immediately before these 10 months (n = 37). All pathways and discharge criteria were identical for patients in each group. A total of 73 patients were included in this retrospective chart review. Two gastric bypass patients were excluded for complications requiring additional surgery (one bleed and one leak). Gastric bypass patients who received a dexmedetomidine infusion required fewer narcotics (66 vs 130 mg of morphine equivalents) than control patients and met discharge criteria on post-op day (POD) 1 more often (61% discharged POD 1 vs 26% discharged POD 1, p = 0.02). Vital signs and pain scores were similar in all groups. Dexmedetomidine infusion perioperatively is safe and may help to minimize narcotic requirements and decrease duration of stay after laparoscopic bariatric procedures. This may have important patient safety ramifications in a patient population with a high prevalence of obstructive sleep apnea. A well-organized prospective, randomized, double-blinded trial is necessary to confirm the benefits of dexmedetomidine suggested by this study.

Impact of routine and long-term follow-up on weight loss after laparoscopic gastric bypass.

BACKGROUND: Weight loss after gastric bypass varies among patients. It is difficult to maintain contact with patients who have undergone surgery several years previously. Continued and long-term follow-up care at a bariatric surgery clinic might be a factor affecting long-term excess weight loss (EWL). METHODS: Patients with 3-4 years of follow-up data after laparoscopic gastric bypass were included in this retrospective analysis. The patients were divided into 3 groups: group 1 patients had attended every scheduled postoperative appointment, group 2 patients had attended every appointment for 1 year before being lost to follow-up, and group 3 patients had been lost to follow-up before 1 year. Comparisons were made to determine the relationship between the length of follow-up and EWL. RESULTS: We identified 34 group 1 patients and 51 group 2 or 3 patients of 130 patients eligible to be included as determined by their date of surgery. The interval since surgery was similar at approximately 3 years. Although the EWL did not differ at 1 year of follow-up (mean EWL 70% for group 1 versus 65% for group 2, P >.05), a significant difference in the EWL was observed at 3-4 years (74% for group 1 versus 61% for group 2 versus 56% for group 3; P <.05). The distance traveled to the clinic was similar for all 3 groups. The most common explanation for missed follow-up appointments was a lack of insurance coverage. CONCLUSION: Laparoscopic gastric bypass patients who attended all scheduled follow-up appointments experienced greater long-term weight loss than those who did not. On-going, multidisciplinary care is likely a critical component in maintaining the benefit after surgery. Patients must be encouraged to continue to attend their bariatric medical appointments, and payors should provide coverage for these visits.

Laparoscopic gastric bypass: risks vs. benefits up to two years following surgery in super-super obese patients.

BACKGROUND: Super-super obesity (body mass index [BMI] >/= 60 kg/m(2)) is thought to be a risk factor for complications and mortality in laparoscopic Roux-en-Y gastric bypass. Excess weight loss has been demonstrated to be diminished compared with less obese patients following surgery. However, we hypothesize that super-super obese patients who undergo laparoscopic gastric bypass can realize major improvements in their health and a good quality of life without a significantly increased risk of complications when compared with less obese patients. METHODS: From July 2002 to July 2005, University of Wisconsin Health bariatric surgeons performed 288 consecutive laparoscopic Roux-en-Y gastric bypass procedures. Patients were divided into 2 groups: BMI >/= 60 kg/m(2) (n = 28) and BMI < 60 kg/m(2) (n = 260). The groups were compared at defined time intervals during a 2-year period following surgery. Comparison criteria included complications, weight loss, comorbidities, and quality of life. RESULTS: Both groups had similar morbidity and mortality rates. Excess weight loss was shown to be less, but total pounds lost were greater, for the super-super obese patients at all postoperative time intervals specified for postoperative analysis. Despite this fact, overall health improved to a similar degree in each group of patients following surgery; both groups also had similar Moorehead-Ardelt quality of life scores. Using the Bariatric Analysis and Reporting Outcome System (BAROS) to categorize outcomes, the average result for a patient in either group of patients would be considered "very good" at 1 year following surgery. CONCLUSIONS: Laparoscopic Roux-en-Y gastric bypass can be accomplished safely even in extremely obese patients. Although excess weight loss in the super-super obese is diminished postoperatively when compared with less obese patients, health is improved and quality of life is good regardless of a patient's preoperative BMI. Therefore, laparoscopic gastric bypass is a good option even in the extremely obese.

The impact of circular stapler diameter on the incidence of gastrojejunostomy stenosis and weight loss following laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Gastrojejunostomy stenosis after laparoscopic Roux-en-Y gastric bypass is a common occurrence. The incidence varies widely among reported series. We evaluated the impact of circular stapler size on the rate of stenosis and weight loss. METHODS: Our initial technique utilized a 21-mm circular stapler to construct the gastrojejunostomy. We switched to a 25-mm stapler after a large preliminary experience. Stenosis was confirmed by endoscopy in patients complaining of the inability to eat or excessive vomiting, and was defined as a gastrojejunostomy diameter less than that of a therapeutic endoscope (11-mm). RESULTS: Stenosis occurred in 23 of 145 patients (15.9%) with a 21-mm gastrojejunostomy. Five of 81 patients with a 25-mm circular stapled anastomosis have developed a stenosis (6.2%, p = 0.03). Weight loss was similar for each sized stapler at 6 and 12 months. CONCLUSIONS: The use of a 25-mm circular stapler in laparoscopic gastric bypass is preferable to a 21-mm stapler. The larger stapler is associated with a significantly decreased incidence of gastrojejunostomy stenosis without compromising early weight loss.

One-year Surgical Outcomes and Costs for Medicaid Versus Non-Medicaid Patients Undergoing Laparoscopic Roux-en-Y Gastric Bypass: A Single-Center Study.

PURPOSE: To compare 1-year outcomes and costs between severely obese Medicaid and non-Medicaid patients who underwent laparoscopic Roux-en-Y gastric bypass surgery. METHODS: This is a single-institution retrospective review comparing 33 Medicaid patients to 99 randomly selected non-Medicaid patients (1:3 case-control). Ninety-day and 1-year outcomes were extracted from the electronic health record. Costs were obtained from the UW information technology division. Bivariate analyses were used to compare study variables. RESULTS: Emergency department visits (48.2% vs. 27.4%; P=0.06) and readmissions (37.0% vs. 14.7%; P=0.01) were more common for Medicaid patients. Medicaid patients had less excess body weight loss (50.7% vs. 65.6%; P=0.001) but similar comorbidity resolution and complication rates. One-year median costs were similar between Medicaid and non-Medicaid patients ($21,160 vs. $24,215; P=0.92). CONCLUSIONS: One-year comorbidity resolution, complications, and costs following laparoscopic Roux-en-Y gastric bypass were similar between Medicaid and non-Medicaid patients. Focusing on reducing emergency department presentations and readmissions would be a high-impact area for future quality improvement initiatives.

Lessons learned from the first 100 cases in a new minimally invasive bariatric surgery program.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a technically demanding procedure with a steep learning curve. Experienced laparoscopic surgeons and bariatric surgeons can learn from the outcomes and complications of their initial experience in LRYGBP. METHODS: Between August of 2002 and July of 2003, we performed our first 100 LRYGBPs. Our surgical technique involves the ante-colic, ante-gastric placement of the Roux-limb. A 21-mm circular stapler is used to create the gastrojejunostomy. The stapler anvil is placed transgastrically. RESULTS: The mean preoperative BMI was 49.7 kg/m(2) (range 37-70). 12% of patients were male. Early complications (14%) included 3 leaks, 4 bleeding episodes and 2 gastrogastric fistulas. There was 1 peri-operative mortality and 1 conversion to laparotomy. Late complications (17%) included stenosis of the gastrojejunostomy which occurred in 14 patients. Leaks occurred more commonly in males (16% vs 1%, P<0.05). Elevated BMI was also found to be a risk factor for leak (BMI 58.7 leak vs 49.3 no leak, P<0.05). Stenosis was often associated with other complications such as leak or marginal ulcer. Stenosis responded well to endoscopic dilation. Co-morbid medical conditions responded to weight loss in all patients, regardless of initial BMI. Mean excess weight loss was 69% at 1 year, but varied according to preoperative BMI. CONCLUSIONS: Careful recording of patient outcomes and complications is important, particularly in a new minimally invasive bariatric surgery program. Review and analysis of specific complications may help to minimize the occurrence of similar subsequent complications.

Laparoscopic gastric bypass results in decreased prescription medication costs within 6 months.

The prevalence of obesity has reached epidemic proportions. The treatment of obesity-related health conditions is costly. Although laparoscopic gastric bypass is expensive, health care costs in obese patients should decrease with subsequent weight loss and overall improved health. Specifically, monthly prescription medication costs should decrease quickly after surgery. Fifty consecutive laparoscopic gastric bypass patients at a university-based bariatric surgery program were enrolled in the study. Medication consumption was prospectively recorded in a database. Patients' monthly prescription (not over-the-counter) medication costs before surgery and 6 months postoperatively were calculated. Retail costs were determined by a query to drugstore.com, an online pharmacy. Generic drugs were selected when appropriate. Costs for diabetic supplies and monitoring were not included in this analysis. Patients were mostly female (86%). Mean body mass index preoperatively was 51 kg/m2. Mean excess weight loss at 6 months was 52%. Patients took an average of 3.7 prescription medications before surgery compared with 1.7 after surgery (P < 0.05). All patients took nonprescription nutritional supplements, including multivitamins, oral vitamin B12, and calcium postoperatively. Laparoscopic gastric bypass resulted in a significant improvement in comorbid health conditions as early as 6 months after surgery. In an unselected group of patients, this led to a substantial overall mean monthly prescription medication cost savings, especially in those with gastroesophageal reflux disease, hypertension, diabetes, and hypercholesterolemia.

Factors associated with readmission after laparoscopic gastric bypass surgery.

BACKGROUND: Studies have demonstrated that laparoscopic Roux-en-Y gastric bypass (RYGB) is associated with the greatest readmission rate among bariatric surgeries. Some readmissions might be avoidable. We sought to evaluate the risk factors for readmission in a high-volume bariatric surgery program at a university hospital in the United States. METHODS: We performed a retrospective review of prospectively maintained data. Patients readmitted within 30 days of laparoscopic RYGB were randomly matched to control patients who had undergone RYGB in the same year but were not readmitted. The readmissions were categorized as technical complications (leak), wound infections, or malaise (nausea, dehydration, or benign abdominal pain). Patients with a wound infection treated in an outpatient setting were also evaluated and compared with the patients admitted with a wound infection. RESULTS: From July 2002 to July 2008, 450 patients underwent RYGB. Readmission occurred in 42 patients (9%). Of these 42 patients, 6 were admitted with wound infections (14%), 18 (43%) with malaise, and 18 (43%) with technical complications. The patients admitted with wound infections were similar to their controls, except that they were more likely to have publicly funded insurance (Medicare or Medicaid) and more likely to present for medical attention to the emergency department after clinic hours. The patients admitted with malaise reported a greater pain score at discharge and were also more likely to have public health insurance than controls. The patients with technical complications did not differ from the control patients in any examined variable. CONCLUSIONS: Patients with publicly funded insurance are at increased risk of readmission after RYGB. Outpatient mechanisms for managing wound infections and malaise might result in decreased readmissions.

Revisional surgery for failed vertical-banded gastroplasty.

Vertical-banded gastroplasty (VBG) was once a common bariatric procedure. It has fallen out of favor due to the emergence of the adjustable gastric band and late complications including band erosion and stenosis. Options for revision include conversion to a Roux-en-Y gastric bypass (RYGB) or VBG reversal via gastrogastrostomy. Patients undergoing revision of a previous VBG were identified. VBG reversal was performed laparoscopically. Conversion to RYGB was performed by both laparotomy and laparoscopy. Perioperative outcomes and long-term weight loss were evaluated. A total of 34 patients with a previous open VBG underwent revision over a nearly 8-year period (January 2003 to September 2010). Conversion to RYGB was performed in 25 (four laparoscopically) and VBG reversal in nine patients. Mean age for all patients was 56.3 years (range 36-70), and VBG had been performed 23 years previously (range 16-30). Patients to undergo VBG reversal were more likely to be male and less likely to be morbidly obese at the time of revision. Operative time and length of stay were shorter for laparoscopic procedures. Complication rates did not differ based on technique or procedure. Patients with a previous VBG may present with complications and obesity decades after the primary procedure. Revisional surgery can be accomplished laparoscopically. Following VBG reversal, most patients gain weight and many become morbidly obese again. Conversion to RYGB is associated with weight loss and resolution of morbid obesity in most patients. When feasible, laparoscopic conversion to RYGB may offer the best outcomes.

Effect of circular staple line buttressing material on gastrojejunostomy failure in laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: To determine the effect of bovine pericardium strip (BPS) reinforcement of the circular stapler on the gastrojejunostomy leak rates and staple line failure after laparoscopic Roux-en-Y gastric bypass (LRYGB) at a university hospital in the United States. Gastrojejunostomy leak after LRYGB is a devastating complication. Various techniques, including buttressing the gastrojejunostomy staple line with biomaterial, have been used in an effort to minimize leaks. METHODS: A total of 350 consecutive patients underwent LRYGB without staple line buttressing. After this initial experience, BPS reinforcement of the gastrojejunostomy was conducted in 81 consecutive patients. BPS reinforcement was not used for the final 69 consecutive patients in this 500 patient series. Circular staple line failures (intraoperative immediate and complete failure of the anastomosis) and leaks were evaluated retrospectively. RESULTS: Three leaks (and no intraoperative staple line failures) occurred in 419 patients without BPS buttressing, all in the first 100 cases of our experience, and 3 leaks and an anastomotic staple line failure occurred in the 81 patients with BPS buttressing (.7% versus 4.9%, P = .02). The body mass index and other potential leak risk factors did not differ between the 2 groups. CONCLUSION: In our experience, buttressing of the circular staple line with BPS during LRYGB was associated with an increased staple line adverse event rate. BPS buttressing of the gastrointestinal circular staple lines should be used with caution.

National bariatric surgery and massive weight loss body contouring survey.

BACKGROUND: As bariatric surgery has become more popular, plastic surgeons have seen increases in post-bariatric surgery body contouring procedures. The aim of the authors' survey was to better understand perspectives of bariatric surgeons toward body contouring procedures and referral patterns to plastic surgeons. METHODS: A questionnaire was sent to 500 surgeon members of the American Society for Metabolic and Bariatric Surgery. Questions focused on bariatric surgery practices, perspectives toward massive weight loss body contouring, and referral patterns. One hundred eighty-eight surveys were analyzed. RESULTS: Sixty-four percent of surgeons surveyed reported that patients ask about body contouring procedures before bariatric procedures. Only 54 percent reported routine counseling on the potential functional and aesthetic consequences of bariatric surgery. Ninety-six percent of bariatric surgeons have access to plastic surgeons, but only 7 percent of bariatric surgeons always refer their patients to a plastic surgeon and 33 percent rarely refer to a plastic surgeon. Fifty-one percent of surgeons report that patients who have undergone body contouring procedures are overall more satisfied with their decision to undergo bariatric surgery versus bariatric patients who have not had body contouring. Seventy-five percent of surgeons reported that patients rarely express any concern regarding their decision to undergo plastic surgery. CONCLUSIONS: Bariatric surgery requires multispecialty care from bariatric and plastic surgeons. Results and outcomes can be improved with body contouring procedures, especially with regard to better self-image, self-confidence, and satisfaction. However, there are deficiencies in pre-bariatric surgery counseling regarding outcomes and discussions of body contouring procedures. Therefore, better methods of referrals to plastic surgeons need to be identified.

Bariatric surgery.

It is estimated that more than 5% of US adults are morbidly obese (body mass index higher than 40). Morbid obesity is associated with adverse health conditions including prolonged morbidity and early mortality while affecting people of lower socioeconomic means. A variety of surgical procedures have evolved over the past 30 years to address this problem with varying degrees of success and longevity. For those patients achieving dramatic weight loss, reconstructive cosmetic surgery is often necessary or desirable. Techniques to achieve this are described.
