Changes in glycemic control and body weight after explantation of the duodenal-jejunal bypass liner.

BACKGROUND AND AIMS: The duodenal-jejunal bypass liner (DJBL) is an endoscopic device that induces weight loss and improves glycemic control in patients with type 2 diabetes mellitus (T2DM). The aim of the current study was to assess the effects of DJBL explantation on glycemic control and body weight. METHODS: This prospective, observational study included only patients with T2DM who had the DJBL implanted for at least 6 months and had a follow-up of at least 12 months after explantation. The primary endpoints were changes in glycosylated hemoglobin A1c (HbA1c) and body weight during the 12 months after explantation. Secondary endpoints were changes in fasting plasma glucose, blood pressure, and plasma lipid levels. RESULTS: In total, 59 patients completed the 12-month follow-up after explantation. During this period body weight increased by 5.6 (standard deviation, 6.4) kg (P < .001) and HbA1c rose from 65 (SD 17) to 70 (SD 20) mmol/mol (P < .001). However, body weight remained 8.0 (SD 8.6) kg (P < .001) lower than before implantation, that is, corresponding to a net total body weight loss of 7.4% (SD 7.6) (P < .001). Although HbA1c was significantly higher 12 months after explantation compared with baseline and the mean daily dose of insulin used was comparable, the number of patients on insulin remained significantly lower than before implantation. CONCLUSIONS: Explantation of the DJBL is associated with weight gain and worsening of glycemic control, although some beneficial effects remained detectable 12 months after explantation. A change in strategy is needed to preserve the beneficial effects of DJBL treatment. (Clinical trial registration number: 746∖100111.).

A short or a long Roux limb in gastric bypass surgery: does it matter?

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) still remains the gold standard in bariatric surgery. However, no consensus exists on the optimal limb lengths to induce maximum weight reduction. The aim of the present study was to assess the effect of a longer alimentary limb (AL) length on weight reduction after RYGB. METHODS: A retrospective analysis of a prospectively collected database of patients who underwent a primary laparoscopic RYGB between January 2001 and March 2011 was performed. Patients received a short AL (SAL; 100 cm) or a long AL (LAL; 150 cm). Primary outcome was weight loss, and secondary outcomes were short- and long-term complication rates. RESULTS: A total of 768 patients received a RYGB during the study period. Of these, 730 consecutive patients were included for long-term analysis and had a mean follow-up (FU) of 37 ± 26 [range 0-120] months; 360 (47 %) patients received a SAL RYGB. Overall %TBWL was 33 ± 9 % after 2 years (FU 74 %) and 28 ± 12 % after 5 years (FU 20 %). No significant differences in %TBWL were found between SAL RYGB and LAL RYGB during the study period. The 30-day mortality rate was 0.13, 9 % overall short-term complication rate and 19 % cumulative long-term complication rate. No differences in complications were found between SAL and LAL RYGB patients. CONCLUSION: Lengthening of the alimentary limb from 100 to 150 cm did not affect post-RYGB weight loss. Overall complication rates were low and comparable in this series of RYGB patients.

Weight reduction and improvement in diabetes by the duodenal-jejunal bypass liner: a 198 patient cohort study.

BACKGROUND: The duodenal-jejunal bypass liner (DJBL) is an endoscopic treatment for patients with type 2 diabetes mellitus (T2DM) and (morbid) obesity. The aim of the current study was to determine its efficacy and safety profile. METHODS: Inclusion criteria for treatment with a DJBL were: age 18-70 years, BMI 28-45 kg/m2, and T2DM with a HbA1c > 48 mmol/mol. Primary outcomes were changes in HbA1c and body weight. Secondary outcomes included changes in blood pressure, lipids, and anti-diabetic medication. Predictive factors for success of treatment with the DJBL were determined. RESULTS: Between 2011 and 2014, 185 out of 198 patients successfully underwent a DJBL implantation procedure, with an intended implantation time of 12 months. In these 185 patients, body weight decreased by 12.8 ± 8.0 kg (total body weight loss of 11.9 ± 6.9 %, p < 0.001), HbA1c decreased from 67 to 61 mmol/mol (p < 0.001) despite a reduction in anti-diabetic medication, and blood pressure and serum lipid levels all decreased. In total, 57 (31 %) DJBLs were explanted early after a median duration of 33 weeks. Adverse events occurred in 17 % of patients. C-peptide ≥1.0 nmol/L and body weight ≥107 kg at screening were independent predictive factors for success. CONCLUSIONS: Treatment with the DJBL in T2DM patients with (morbid) obesity results in improvement in glucose control, a reduction in anti-diabetic medication, and significant weight loss. The largest changes are observed within the first 3-6 months. Initial C-peptide levels and body weight may help to select patients with the greatest chance of success.

Safety experience with the duodenal-jejunal bypass liner: an endoscopic treatment for diabetes and obesity.

BACKGROUND: The duodenal-jejunal bypass liner (DJBL) is a new, device-based endoscopic treatment for type 2 diabetes mellitus (T2DM) and obesity. OBJECTIVE: To report serious safety events of subjects treated with the DJBL while offering a simple guideline to mitigate risk. DESIGN: Single-center observational study. SETTING: Tertiary referral center. PATIENTS: For commercial use, patients were eligible for implantation of the DJBL when they met the following criteria: age 18 to 65 years, body mass index 28 to 45 kg/m(2), T2DM, and negative serum Helicobacter pylori test. INTERVENTIONS: Endoscopic implantation of the DJBL. MAIN OUTCOME MEASUREMENTS: Adverse events, serious adverse events, early explantation. RESULTS: Between October 2007 and January 2014, 152 of 165 planned implantations (92%) and 94 explantations were performed in our center. Significant weight loss and improvement in T2DM and other cardiovascular parameters were achieved. Early removal of the device occurred because of persistent GI symptoms in 16 patients (11%). Serious adverse events were observed in a subset of patients: 7 GI bleeds, 5 of which required early removal; 2 cases of pancreatitis; 1 case of hepatic abscess; and 1 obstruction of the sleeve. Explantation resulted in an esophageal tear in 2 cases. LIMITATIONS: Single-center study. CONCLUSION: The DJBL improves glycemic control while causing weight loss. The safety profile of the DJBL demonstrates a reasonable tolerability profile. However, serious safety adverse events can occur. Patient selection, expert use of the device at placement and removal, and the supportive care of an experienced multidisciplinary team are key for safe and effective use of the DJBL.

Acute pancreatitis as an adverse event in patients with the duodenal-jejunal bypass liner.

Placement of the duodenal-jejunal bypass liner (DJBL) is a minimally invasive technique for the management of patients with type 2 diabetes mellitus and obesity. Acute pancreatitis was seen in 5 of 167 patients (3 %) in our series. It is suggested that acute pancreatitis in patients with the DJBL results from either direct blockage or edema of the major duodenal papilla, which may be caused by the following: migration of the anchor of the DJBL, accumulation of food debris between the liner and the duodenal wall, or reflux of duodenal contents into the pancreatic duct due to intraluminal hypertension caused by the liner. Early removal of the DJBL resulted in fast and complete recovery, whereas delayed diagnosis and removal led to severe, necrotizing acute pancreatitis.

Correction to: Adequate Multivitamin Supplementation after Roux-En-Y Gastric Bypass Results in a Decrease of National Health Care Costs: a Cost-Effectiveness Analysis.

In the original article, there are some incorrect data in the "Results" section of the Abstract.

A long biliopancreatic and short alimentary limb results in more weight loss in revisional RYGB surgery. Outcomes of the randomized controlled ELEGANCE REDO trial.

BACKGROUND: For a number of years the laparoscopic adjustable gastric band has been one of the leading bariatric procedures with good short-term outcomes. However, inadequate weight loss, weight regain, and other band-related complications in the long term led to an increase in revisional Roux-en-Y gastric bypass (RYGB) procedures. Lengthening the biliopancreatic limb, a relatively simple and safe adjustment of the standard technique, could improve the results of the revisional procedure. OBJECTIVES: The aim of this randomized controlled trial was to evaluate the effect of a long biliopancreatic limb RYGB (LBP-GB) and standard RYGB (S-GB) as revisional procedure after laparoscopic adjustable gastric band. SETTING: General hospital specialized in bariatric surgery METHODS: One hundred forty-six patients were randomized in 2 groups; 73 patients underwent an S-GB (alimentary/biliopancreatic limb 150/75 cm), and 73 patients underwent LBP-GB (alimentary/biliopancreatic limb 75/150). Weight loss, remission of co-morbidities, quality of life, and complications were assessed during a period of 4 years. RESULTS: Baseline characteristics between the groups were comparable. At 48 months the follow-up rate was 95%. Mean total weight loss after 24 months was 27% for LBP-GB versus 22% S-GB (P = .015); mean total weight loss after 48 months was 23% and 18%, respectively (P = .036). No significant differences in other parameters were found between the groups. CONCLUSIONS: A LBP-GB as revisional procedure after a failing laparoscopic adjustable gastric band improves short- and long-term total weight loss compared with an S-GB. Together with future modifications this technically simple adjustment of the RYGB could significantly improve disappointing results after revisional surgery.

Adequate Multivitamin Supplementation after Roux-En-Y Gastric Bypass Results in a Decrease of National Health Care Costs: a Cost-Effectiveness Analysis.

INTRODUCTION: Patients with morbid obesity undergoing metabolic surgery are prone to develop vitamin and mineral deficiencies, which may worsen in time. In order to prevent these deficiencies after metabolic surgery, all patients are advised to take daily multivitamin supplementation. The aim of the study was to assess the cost-effectiveness of specially developed multivitamins (WLS Forte®) for metabolic surgery and over-the-counter (standard) multivitamin supplementation (sMVS). METHODS: This cost-effectiveness analysis was preformed alongside an RCT for the Netherlands. Between June 2011 and March 2012, a total of 148 patients were randomized to one tablet daily of either WLS Forte® or sMVS. The patients were followed for 12 months. Data on costs within the health sector and outside the health sector were collected. The primary outcome is financial and logistic advantages, in terms of less patient visits to the outpatient department and the relevant costs to the employer due to absenteeism. RESULTS: In total, 10 (14%) patients in the WLS Forte® group versus 23 (30%) patients in the sMVS group developed a deficiency. The costs for the WLS forte® supplement were €38 versus €23 for sMVS. Additional return visits and associated costs for medical staff were the largest costs, up to 43% in the sMVS group. Total costs for supplementation with sMVS were €243 versus €134 for WLS Forte®. CONCLUSION: Preventing deficiencies with WLS Forte® seem initially more expensive than sMVS. However, treatment with WLS Forte® resulted in less vitamin and mineral deficiencies, which eventually resulted in less overall costs.

Long-term nutritional status in patients following Roux-en-Y gastric bypass surgery.

BACKGROUND & AIMS: Roux-en-Y gastric bypass (RYGB) is an effective treatment for obesity. However, it also leads to multiple nutritional deficiencies. Much is known about the short term prevalence, but hardly any long term data is available on deficiencies. The aim of this study was to assess the long term outcome of nutritional status after RYGB. METHODS: We performed a retrospective analysis of prospectively collected data obtained from 51 morbidly obese patients who underwent a primary laparoscopic RYGB. Primary outcomes were iron, vitamin B12 and vitamin D deficiencies. Secondary outcomes were deficiencies of other vitamins and minerals and compliance of the patients to multivitamin use. RESULTS: The mean follow-up was 81 ± 27 months. A total of 35%, 16% and 55% of the patients had deficiencies for iron, vitamin B12 and vitamin D respectively. Sixty-nine percent of patients used a (nonspecific) multivitamin supplement on a daily basis. Patients with multivitamin usage had a lower rate of iron deficiency (26% vs. 56%, p = 0.034), vitamin B12 (11% vs. 25%, p = 0.46) and vitamin D (46% vs. 75%, p = 0.07), compared to non-compliant patients. CONCLUSIONS: Nutritional deficiencies are common after a RYGB operation. Therefore, strict follow-up by a bariatric surgeon, endocrinologist or general practitioner is required, both short and long term.

Treatment of Vitamin and Mineral Deficiencies After Biliopancreatic Diversion With or Without Duodenal Switch: a Major Challenge.

BACKGROUND: Vitamin and mineral deficiencies are a major concern after biliopancreatic diversion (BPD) and BPD with duodenal switch (BPD/DS). Evidence-based guidelines how to prevent or how to treat deficiencies in these patients are currently lacking. The aim of the current study is to give an overview of postsurgical deficiencies and how to prevent and treat these deficiencies. METHODS: Retrospective evaluation of a 1-year structured monitoring and treatment schedule for various deficiencies in 34 patients after BPD or BPD/DS. RESULTS: Patients were introduced into the program 12-90 months after surgery. Vitamin B1, B6, B9, and B12 deficiencies could be prevented by mean daily doses of 2.75 mg, 980 µg, 600 µg, and 350 µg, respectively. However, many patients continued to develop deficiencies of vitamin A, D, iron, calcium, and zinc despite major dose adjustments. Current observations suggest that at least total daily doses of 200 mg Fe in premenopausal women and 100 mg in men, 100 mg of Zinc, 3000 mg of calcium, and weekly doses of at least 50,000 IU solubilized vitamin A and vitamin D are needed to prevent the occurrence of major deficiencies. CONCLUSION: Exceptionally high supplementation doses are needed to prevent and treat vitamin and mineral deficiencies in patients after BPD or BPD/DS. Further refinement and simplification of treatment schedules is needed. Focus on improvement of compliance to treatment is recommended.

A Longer Biliopancreatic Limb in Roux-en-Y Gastric Bypass Improves Weight Loss in the First Years After Surgery: Results of a Randomized Controlled Trial.

BACKGROUND: Despite the fact that the RYGB is performed on a broad scale worldwide as a reliable treatment for morbid obesity, there is no uniform technique for this operation. A number of studies have tried to demonstrate an additional weight loss effect by lengthening the alimentary limb, but to no avail. At this moment in time, the role of the biliopancreatic limb on weight loss is for the greater part unknown. The aim of this randomized controlled trial was to compare the effect on weight loss of a long biliopancreatic limb Roux-en-Y gastric bypass (LBP-GB) with a standard RYGB (S-GB). METHODS: A LBP-GB (BPL 150 cm, alimentary limb 75 cm) was compared with a S-GB (BPL 75 cm, alimentary limb 150 cm). One hundred forty-six patients were randomized in two groups. Weight loss, morbidity, reduction of comorbidities, nutritional status, and quality of life were measured during a period of 4 years. RESULTS: Patient characteristics were comparable in both groups. Mean EWL in the LBP-GB group after 12, 24, 36, and 48 months was 81, 85, 78, and 72% respectively versus 71, 73, 68, and 64% in the S-GB group. The %EWL difference between groups was significant as soon as 9 months postoperatively and continued throughout the follow-up period. CONCLUSIONS: While LBP-GB achieved a significant increase in %EWL in the first years after surgery, no difference in long-term %TWL was observed after 4 years. In this study, the advantage of LBP-GB with respect to weight loss is modest, but shows promising gripping points for future improvements in RYGB design.

Efficacy of oral compared with intramuscular vitamin B-12 supplementation after Roux-en-Y gastric bypass: a randomized controlled trial.

Background: After Roux-en-Y gastric bypass (RYGB), patients often develop a vitamin B-12 deficiency. Objective: Our objective was to investigate whether oral supplementation increases and normalizes low vitamin B-12 concentrations (vitamin B-12 > 200 pmol/L) in RYGB patients as compared to intramuscular injections. Design: A randomized controlled trial in RYGB patients with subnormal serum B-12 concentrations was performed. One group (IM B-12) received bimonthly intramuscular hydroxocobalamin injections (2000 µg as loading dose and 1000 µg at follow-up) for 6 mo. The second group (oral B-12) received daily doses of oral methylcobalamin (1000 µg). Serum vitamin B-12 was determined at baseline (T0) and at 2 (T1), 4 (T2), and 6 mo (T3) after start of treatment. Concentrations of the secondary markers methylmalonic acid (MMA) and homocysteine (Hcy) were measured at T0 and T3. Results: Fifty patients were included and randomized, 27 in IM B-12 and 23 in oral B-12. The median vitamin B-12 concentration at T0 was 175 pmol/L (range: 114-196 pmol/L) for IM B-12 and 167 pmol/L (range: 129-199 pmol/L) for oral B-12. Vitamin B-12 normalized in all individuals, and there was no significant difference in vitamin B-12 between the two groups. MMA and Hcy concentrations decreased significantly after 6 mo within each group (P < 0.001 and P < 0.001 for MMA and P = 0.03 and P = 0.045 for Hcy, respectively). There was no significant difference between the groups at 6 mo for both MMA and Hcy (P = 0.53 and P = 0.79). Conclusion: The efficacy of oral vitamin B-12 supplementation was similar to that of hydroxocobalamin injections in the present study. Oral supplementation can be used as an alternative to hydroxocobalamin injections to treat RYGB patients with low values of serum vitamin B-12. This trial was registered at clinicaltrials.gov as NCT02270749.

Management of vitamin K deficiency after biliopancreatic diversion with or without duodenal switch.

BACKGROUND: Reduced serum vitamin K levels are frequently observed after biliopancreatic diversion (BPD) and BPD with duodenal switch (BPD/DS). The criteria for treatment are not precisely defined. OBJECTIVES: To assess the effects of standardized vitamin K supplementation in patients who develop vitamin K deficiency after BPD or BPD/DS. SETTING: Teaching hospital specializing in bariatric surgery. METHODS: Serum vitamin K levels, clotting times, and vitamin K-dependent coagulation factors were measured after an overnight fast at baseline and then at 4 days and 1, 4, and 52 weeks after the start of vitamin K supplementation in 10 consecutive patients who had developed severe vitamin K deficiency after BPD or BPD/DS. Vitamin K was administered in a dose of 5 mg/d for 1 week, followed by a maintenance dose of 5 mg once a week. RESULTS: At baseline, all patients had serum vitamin K1 levels below the limit of detection, but none reported symptoms of easy bleeding. Minor prolongation of the prothrombin time and minimal decreases of some coagulation factors were observed in a minority of patients. During the first week of vitamin K loading, median serum vitamin K1 levels rose into the high normal range. During maintenance treatment, median vitamin K1 levels settled in the low normal range. CONCLUSION: Vitamin K1 deficiency in patients with BPD or BPD/DS is not commonly associated with bleeding or clinically relevant decreases in coagulation factor activity. We hypothesize that vitamin K2 production in the large intestine is usually sufficient to compensate for vitamin K1 deficiency and to maintain total liver vitamin K stores within the range required for (near) normal coagulation factor production.

An optimized multivitamin supplement lowers the number of vitamin and mineral deficiencies three years after Roux-en-Y gastric bypass: a cohort study.

BACKGROUND: Vitamin and mineral deficiencies are common after Roux-en-Y gastric bypass (RYGB) surgery. In particular, inadequate serum concentrations of ferritin and vitamin B12 have been found in 11% and 23% (respectively) of patients using a standard multivitamin supplement (sMVS) 1 year after RYGB. OBJECTIVE: To evaluate the effectiveness and safety of Weight Loss Surgery (WLS) Forte® (a pharmaceutical-grade, optimized multivitamin supplement) compared with an sMVS and a control group (nonuser) 3 years after RYGB. SETTING: General hospital specialized in bariatric surgery. METHODS: A follow-up cohort study of a triple-blind randomized, controlled clinical trial. RESULTS: At baseline 148 patients were enrolled (74 [50%] in the sMVS group and 74 [50%] in the WLS Forte group). After a mean follow-up of 36 months, 11 (7%) patients were lost to follow-up, of whom 2 were secondary to death. At the end of the study, 11 (17%) patients in the WLS Forte and 17 (24%) in the sMVS group stopped using a supplement. In addition, 64 (47%) patients were using WLS Forte and 45 (33%) patients a sMVS. Patient characteristics and follow-up length were comparable between the groups. Significantly more patients were diagnosed with anemia (16% versus 3% [P = .021]), a ferritin deficiency (14% versus 3% [P = .043]), and a zinc deficiency (8% versus 0% [P = .033]) in the sMVS group compared with WLS Forte. Five patients developed a vitamin B12 deficiency while using WLS Forte, versus 15 of sMVS users (P = .001). No adverse events occurred that were related to supplement use. CONCLUSION: At 3 years postoperative of RYGB, an optimized multivitamin supplement (WLS Forte) was more effective in reducing anemia and ferritin, vitamin B12, and zinc deficiencies compared with a standard supplement and control.

Subclinical hypothyroidism and its relation to obesity in patients before and after Roux-en-Y gastric bypass.

BACKGROUND: Subclinical hypothyroidism (SH), defined as a raised serum thyroid-stimulating hormone (TSH) with a normal free thyroxine (FT4), is occasionally observed in morbidly obese patients. OBJECTIVES: It is currently not known whether thyroid hormone treatment is indicated. The aim of the present study was to assess the changes in thyroid hormone levels in thyroxine-naïve patients with SH in response to weight loss induced by Roux-en-Y gastric bypass (RYGB). SETTING: General hospital specialized in bariatric surgery. METHODS: Serum levels of TSH and FT4 were measured at baseline in 503 patients presenting for RYGB. In patients diagnosed with SH, these measurements were repeated 12 months postoperatively. RESULTS: SH de novo was present in 71 out of 503 patients (14.1%). One-year follow-up was available in 61 out of 71 patients (86%). TSH level >10 mU/L was observed in 3 patients (.5%). RYGB induced a decrease in BMI from 47±8 kg/m(2) to 33±6 kg/m(2) at 12-month follow-up (P<.001), and this was associated with a decrease in TSH from 5.8±2.0 to 2.8±1.3 mU/L (P<.001) and a decrease in FT4 from 15.2±2.1 to 13.9±2.3 pmol/L (P<.001), respectively. SH completely resolved in 53 (87%) of the de novo cases. CONCLUSION: The prevalence of SH de novo is high in morbidly obese patients. After RYGB it resolves in about 90% of patients. This high degree of spontaneous recovery suggests that follow-up alone is sufficient in the majority of patients.

Vitamin and Mineral Deficiencies After Biliopancreatic Diversion and Biliopancreatic Diversion with Duodenal Switch--the Rule Rather than the Exception.

INTRODUCTION: Malabsorptive bariatric procedures, like the biliopancreatic diversion (BPD) and BPD with duodenal switch (BPD/DS), have excellent results in terms of weight loss. However, these malabsorptive techniques are associated with severe malnutrition and vitamin deficiencies. The aim of this study was to evaluate the vitamin and mineral status after BPD and BPD/DS in the long term. METHODS: All patients who underwent BPD or BPD/DS were selected and invited for an additional follow-up (FU) visit, including blood sampling for vitamin and mineral levels. RESULTS: Forty patients completed the blood sampling with a median FU of 42 (range 12-90) months. At that time, all patients used some kind of supplementation. However, 93 % of all patients were diagnosed with a deficiency. There were no significant differences in mean serum level vitamins and minerals between BPD and BPD/DS. Forty-three per cent of the patients were anaemic, and 40 % had an iron deficiency (ID). High deficiency rates for fat-soluble vitamins were present: vitamin A in 28 %, vitamin D in 60 %, vitamin E in 10 % and vitamin K in 60 % of the patients. Hypervitaminosis was found in 43 % of the patients for vitamin B1 and in 50 % for vitamin B6. CONCLUSION: High numbers of vitamin and mineral deficiencies were found after BPD and BPD/DS despite vitamin supplementation. Anaemia, ID and deficiencies for fat-soluble vitamins are frequently diagnosed. Repeated monitoring is necessary to detect deficiencies at an early stage. Taking all of this into consideration, a stringent multivitamin supplementation regimen should be implemented after malabsorptive procedures.

Secondary surgery after sleeve gastrectomy: Roux-en-Y gastric bypass or biliopancreatic diversion with duodenal switch.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a stand-alone procedure with good short-term results for weight loss. However, in the long-term, weight regain and other complications are reported. Demand for secondary surgery is rising, partly for these reasons. OBJECTIVES: To review the indications and effects of secondary surgery, biliopancreatic diversion with duodenal switch (BPD/DS) versus laparoscopic Roux-en-Y gastric bypass (LRYGB), after LSG. METHODS: Data from all patients who underwent revision of LSG was retrospectively analyzed, concerning data on indications for secondary surgery, weight loss, and complications. RESULTS: 43 Patients underwent secondary surgery after LSG; 25 BPD/DS and 18 LRYGB, respectively. Main indications for secondary surgery were inadequate weight loss (n = 17 [40%]) and weight regain (n = 8 [19%]). For these indications, the median excess weight loss was greater for BPD/DS (59% [range 15-113]) compared to LRYGB (23% [range -49-84]) (P = .008) after 34 months (range 14-79). In case of dysphagia or gastroesophageal reflux disease the complaints resolved after converting to LRYGB. BPD/DS patients were more likely to develop a short-term complication and vitamin deficiencies compared to LRYGB. CONCLUSIONS: Secondary surgery of LSG to BPD/DS or LRYGB is feasible with slightly more complications after BPD/DS. Conversion to LRYGB is preferred in cases of dysphagia or gastroesophageal reflux disease. In cases of weight regain or insufficient weight loss after LSG, patients had better weight loss with a BPD/DS; however, this procedure has the risk of complications, such as severe vitamin deficiencies.

Trends in heart failure incidence and survival in a community-based population.

CONTEXT: The epidemic of heart failure has yet to be fully investigated, and data on incidence, survival, and sex-specific temporal trends in community-based populations are limited. OBJECTIVE: To test the hypothesis that the incidence of heart failure has declined and survival after heart failure diagnosis has improved over time but that secular trends have diverged by sex. DESIGN, SETTING, AND PARTICIPANTS: Population-based cohort study using the resources of the Rochester Epidemiology Project conducted in Olmsted County, Minnesota. Patients were 4537 Olmsted County residents (57% women; mean [SD] age, 74 [14] years) with a diagnosis of heart failure between 1979 and 2000. Framingham criteria and clinical criteria were used to validate the diagnosis MAIN OUTCOME MEASURES: Incidence of heart failure and survival after heart failure diagnosis. RESULTS: The incidence of heart failure was higher among men (378/100 000 persons; 95% confidence interval [CI], 361-395 for men; 289/100 000 persons; 95% CI, 277-300 for women) and did not change over time among men or women. After a mean follow-up of 4.2 years (range, 0-23.8 years), 3347 deaths occurred, including 1930 among women and 1417 among men. Survival after heart failure diagnosis was worse among men than women (relative risk, 1.33; 95% CI, 1.24-1.43) but overall improved over time (5-year age-adjusted survival, 43% in 1979-1984 vs 52% in 1996-2000, P<.001). However, men and younger persons experienced larger survival gains, contrasting with less or no improvement for women and elderly persons. CONCLUSION: In this community-based cohort, the incidence of heart failure has not declined during 2 decades, but survival after onset of heart failure has increased overall, with less improvement among women and elderly persons.

Quality of life is impaired in association with the need for prolonged postoperative therapy by somatostatin analogs in patients with acromegaly.

OBJECTIVE: To assess the influence of long-acting somatostatin analogs (SSTA) after initial pituitary surgery on long-term health-related quality of life (HR-QoL) in relation to disease control in patients with acromegaly. DESIGN: This is a cross-sectional study in two tertiary referral centers in The Netherlands. PATIENTS AND METHODS: One hundred and eight patients with acromegaly, in whom transsphenoidal (n=101, 94%) or transcranial (n=7, 6%) surgery was performed. Subsequently, 46 (43%) received additional radiotherapy and 41 (38%) were on postoperative treatment with SSTA because of persistent or recurrent disease at the time of study. All subjects filled in standardized questionnaires measuring HR-QoL. Disease control at the time of study was assessed by local IGF1 SDS. RESULTS: IGF1 SDS were slightly higher in patients treated with SSTA in comparison with patients without use of SSTA (0.85±1.52 vs 0.25±1.21, P=0.026), but the percentage of patients with insufficient control (IGF1 SDS >2) was not different (17 vs 9%, P=0.208). Patients using SSTA reported poorer scores on most subscales of the RAND-36 and the acromegaly QoL and on all subscales of the multidimensional fatigue inventory-20. A subgroup analysis in patients with similar IGF1 levels (SSTA+, n=26, IGF1 SDS 0.44±0.72 vs SSTA-, n=44, IGF1 SDS 0.41±0.65) revealed worse scores on physical functioning, physical fatigue, reduced activity, vitality, and general health perception across all HR-QoL questionnaires in patients treated with SSTA. CONCLUSION: QoL is impaired in association with the need for prolonged postoperative therapy by SSTA in patients with acromegaly despite similar IGF1 levels.
