In this study involving severely obese patients with type 2 diabetes, Roux-en-Y gastric bypass and biliopancreatic diversion achieved better glucose control than conventional medical therapy as assessed at 2 years. The prevalence of type 2 diabetes mellitus is rapidly increasing worldwide, in parallel with the current obesity epidemic. In 2010, the global prevalence of type 2 diabetes was estimated at 8.3% of the adult population, a proportion that is projected to increase to 9.9% by 2030. 1 As many as 23% of patients with morbid obesity have type 2 diabetes, 2 and the prevalence of screening-detected diabetes is 8%. 2 Global spending on diabetes was estimated to be at least $376 billion in 2010 and projected to be $490 billion in 2030. 3 Conventional medical treatment of type 2 diabetes only partially achieves adequate . . .

OBJECTIVE:--The purpose of this study was to clarify the effects of maternal obesity on insulin sensitivity and secretion in offspring. RESEARCH DESIGN AND METHODS--Fifty-one offspring of both sexes of obese (Ob group) and 15 offspring of normal-weight (control group) mothers were studied. Plasma glucose, insulin, and C-peptide were measured during an oral glucose tolerance test (OGTT). Insulin sensitivity was calculated using the oral glucose insulin sensitivity index, and insulin secretion and β-cell glucose sensitivity were computed by a mathematical model. Fasting leptin and adiponectin were also measured. Body composition was assessed by dual-X-ray absorptiometry. RESULTS:--No birth weight statistical difference was observed in the two groups. Of the Ob group, 69% were obese and 19% were overweight. The Ob group were more insulin resistant than the control group (398.58 ± 79.32 vs. 513.81 ± 70.70 ml⁻¹ · min⁻¹ · m⁻² in women, P < 0.0001; 416.42 ± 76.17 vs. 484.242 ± 45.76 ml⁻¹ · min⁻¹ · m⁻² in men, P < 0.05). Insulin secretion after OGTT was higher in Ob group than in control group men (63.94 ± 21.20 vs. 35.71 ± 10.02 nmol · m⁻², P < 0.01) but did not differ significantly in women. β-Cell glucose sensitivity was not statistically different between groups. A multivariate analysis of variance showed that maternal obesity and offspring sex concurred together with BMI and β-cell glucose sensitivity to determine the differences in insulin sensitivity and secretion observed in offspring. CONCLUSIONS:--Obese mothers can give birth to normal birth weight babies who later develop obesity and insulin resistance. The maternal genetic/epigenetic transmission shows a clear sexual dimorphism, with male offspring having a higher value of insulin sensitivity (although not statistically significant) associated with significantly higher insulin secretion than female offspring.

OBJECTIVE: The surgical option could represent a valid alternative to medical therapy in some diabetic patients. However, no data are available on long-term effects of metabolic surgery on diabetic complications. We aimed to determine whether patients with newly diagnosed type 2 diabetes who underwent bilio-pancreatic diversion (BPD) had less micro- and macrovascular complications than those who received conventional therapy. RESEARCH DESIGN AND METHODS: This was an unblinded, case-controlled trial with 10-years' follow-up, conducted from July 1998 through October 2009 at the Day Hospital of Metabolic Diseases, Catholic University, Rome, Italy. A consecutive sample of 110 obese patients (BMI >35 kg/m²) with newly diagnosed type 2 diabetes was enrolled. The study was completed by 50 subjects. The main outcome measure was long-term effects (10 years) of BPD versus those associated with conventional therapy on microvascular outcome, micro- and macroalbuminuria, and glomerular filtration rate (GFR). Secondary measures included macrovascular outcomes, type 2 diabetes remission, glycated hemoglobin, and hyperlipidemia. RESULTS: Ten-year GFR variation was -45.7 ± 18.8% in the medical arm and 13.6 ± 24.5% in the surgical arm (P < 0.001). Ten-year hypercreatininemia prevalence was 39.3% in control subjects and 9% in BPD subjects (P = 0.001). After 10 years, all BPD subjects recovered from microalbuminuria, whereas microalbuminuria appeared or progressed to macroalbuminuria in control subjects. Three myocardial infarctions, determined by electrocardiogram, and one stroke occurred in control subjects. After the 10-year follow-up, coronary heart disease (CHD) probability was 0.22 ± 0.10 and 0.05 ± 0.04 in the medical and surgical groups, respectively (P < 0.001). Remission from type 2 diabetes was observed in all patients within 1 year of surgery. Surgical and medical subjects had lost 34.60 ± 10.25 and 0.38 ± 6.10% of initial weight at the 10-year follow-up (P < 0.001). CONCLUSIONS: Renal and cardiovascular complications were dramatically reduced in the surgical arm, indicating long-term benefits of BPD on diabetic complications, at least in the case of morbid obesity with decompensated type 2 diabetes.

Background The principle to avoid surgery for haemorrhoids and/or anal fissure in Crohn’s disease (CD) patients is still currently valid despite advances in medical and surgical treatments. In this study we report our prospectively recorded data on medical and surgical treatment of haemorrhoids and anal fissures in CD patients over a period of 8 years. Methods Clinical data of patients affected by perianal disease were routinely and prospectively inserted in a database between October 2003 and October 2011 at the Department of Surgery, Tor Vergata University Hospital, Rome. We reviewed and divided in two groups records on CD patients treated either medically or surgically according to the diagnosis of haemorrhoids or anal fissures. Moreover, we compared in each group the outcome in patients with prior diagnosis of CD and in patients diagnosed with CD only after perianal main treatment. Results Eighty-six CD patients were included in the study; 45 were treated for haemorrhoids and 41 presented with anal fissure. Conservative approach was initially adopted for all patients; in case of medical treatment failure, the presence of stable intestinal disease made them eligible for surgery. Fifteen patients underwent haemorrhoidectomy (open 11; closed 3; stapled 1), and two rubber band ligation. Fourteen patients required surgery for anal fissure (Botox ± fissurectomy 8; LIS 6). In both groups we observed high complication rate, 41.2% for haemorrhoids and 57.1% for anal fissure. Patients who underwent haemorrhoidectomy without certain diagnosis of CD had significantly higher risk of complications. Conclusions Conservative treatment of proctologic diseases in CD patients has been advocated given the high risk of complications and the evidence that spontaneous healing may also occur. From these preliminary results a role of surgery is conceivable in high selected patients, but definitve conclusions can’t be made. Further randomized trials are needed to establish the efficacy of the surgical approach, giving therapeutic recommendations and guidelines.

Background The effectiveness of restrictive procedures has been inferior to that of malabsorbitive ones. Recent variants of restrictive procedures, i.e., gastric banding and sleeve gastrectomy, confirm the strive for more efficacious solutions with less complications. We investigated the balance between effectiveness and complications for a new restrictive procedure, a Transoral Endoscopic Vertical Gastroplasty (TOGa®) Methods Seventy-nine morbidly obese patients were submitted to one out of three surgical procedures: TOGa® (29 patients), laparoscopic gastric bypass (LRYGBP; 20 patients), and biliopancreatic diversion (BPD; 30 patients). Mean BMI were 41.7 (35.4–46.6), 44.8 (36.4–54), and 47.5 (41–60.3), respectively. All the patients reached a 2-year follow-up. Results In TOGa® group BMI, respectively at 12 and 24 months, was 34.5 and 35.5, with 44 and 48.3 % of patients with BMI lower than 35. In LRYGBP group, BMI was 30.7 and 29.2 kg/m 2 , with 80 and 85 % of patients with BMI < 35. In BPD group, BMI was 30 and 29.6 kg/m 2 , with 100 and 93.3 % of patients with BMI < 35. In TOGa® group, 59 % of patients with an initial BMI < 45 reached a BMI < 35, in comparison to 48 % recorded in the whole group and to 14.3 % in patients with initial BMI ≥ 45. Conclusions In selected patients, TOGa®, was associated with good results after two years in terms of weight loss, even in comparison with LRYGBP and BPD. Minimal trauma, absence of complications, and short hospital stay justify this procedure for patients with low BMI.

Background Bilio-pancreatic diversion (BPD) induces permanent weight loss in previously severe obese patients through a malabsorptive mechanism. The aim of the study was to evaluate the modifications of circulating thyroid hormones after BPD, a surgical procedure which interferes with the entero-hepatic circulation of biliary metabolites. Methods Forty-five patients were studied before and 2 years after BPD. Thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), anti-thyroid antibodies, iodine urinary excretion, lipid profile, insulin and glucose plasma levels were assessed. The insulin-resistance HOMA IR index was calculated, and colour Doppler ultrasonography of the neck was performed. Results The subjects (23%) had subclinical hypothyroidism prior to BPD (TSH levels above the normal range with normal fT3 and fT4 levels). After 2 years 40.42% of the population showed subclinical hypothyroidism, while 6.3% became frankly hypothyroid, all of them with no evidence of auto-immune thyroiditis. Most of the patients, who became sub-clinically hypothyroid only following BPD, had already thyroid alterations at the sonogram (multi-nodular euthyroid goiter and thyroidal cysts) prior to surgery. Conclusions BPD increases the prevalence of subclinical or even frank hypothyroidism, without causing a defect in thyroid function itself, through several integrated mechanisms. (1) It induces iodine malabsorption, which is partially compensated by iodine excretion contraction. (2) The entero-hepatic open circulation determines fT3 loss, which induces subclinical or frank hypothyroidism in patients with pre-existing thyroid alterations, interfering also with the weight loss progress. Iodine supplementation should be recommended in those patients reporting thyroid alterations at the sonogram prior to BPD, LT4 therapy should be strictly monitored in patients suffering of subclinical hypopthiroidism and T3 therapy should eventually be considered for patients diagnosed with frank hypothyroidism prior to BPD.
