Surgery for degenerative rotator cuff tears: a health technology assessment

Source at https://www.fhi.no/.Vi har utarbeidet en fullstendig metodevurdering av kirurgi med sutur sammenlignet med ikke-kirurgisk behandling ved degenerativ fulltykkelse rotatorcuff-ruptur. Vi inkluderte fem randomiserte og 18 ikke-randomiserte studier. Vi sammenstilte studiene i metaanalyser og vurderte tilliten til effektestimatene med GRADE-tilnærmingen. For pasienter med ruptur i én sene gir kirurgi liten eller ingen klinisk relevant forskjell i smerte, nattesmerte, funksjon, pasienttilfredshet og helserelatert livskvalitet sammenlignet med ikke-kirurgisk behandling ved ett år (GRADE: middels til lav). For pasienter med ruptur i én eller to sener gir kirurgi litt høyere pasienttilfredshet, men liten eller ingen klinisk relevant forskjell i smerte, nattesmerte, funksjon og helserelatert livskvalitet sammenlignet med ikke-kirurgisk behandling ved ett år (GRADE: middels til lav). Re-ruptur / manglende tilheling forekom hos mellom 5 % og 35 % seks måneder til ti år etter kirurgi og økt rupturstørrelse hos 59 % etter ti år ved ikke-kirurgisk behandling (GRADE: ikke vurdert). Det ble rapportert få alvorlige uønskede hendelser, men kunnskapsgrunnlaget her er tynt og vi er usikre på absolutt risiko. Den helseøkonomiske hovedanalysen viste at kirurgi er det mest kostbare alternativet, med en kostnadsforskjell på ca 36 000 kroner og en forventet akkumulert forskjell i effekt over fem år på 0,09 QALYs. Dette gir en IKER på 389 035 kroner per QALY. • Potensielle årlige kostnadsbesparelser ved å velge kun ikke-kirurgisk behandling framfor kirurgi kan utgjøre inntil 81 millioner kroner. Estimatet er usikkert, og vil antakelig være noe lavere siden kirurgi vil være et behandlingsalternativ for enkelte pasienter. </uli

A novel technique of Roux-en-Y gastric bypass reversal for postprandial hyperinsulinemic hypoglycaemia: a case report

We describe an evaluation of the effects of partial Roux-en-Y gastric bypass (RYGB) reversal on postprandial hyperinsulinaemic hypoglycaemia, insulin and GLP-1 levels.A 37 year old man was admitted with neuroglycopenia (plasma-glucose 1.6mmol/l) 18 months after RYGB, with normal 72h fasting test and abdominal CT. Despite dietary modifications and medical treatment, the hypoglycaemic episodes escalated in frequency. Feeding by a gastrostomy tube positioned in the gastric remnant did not prevent severe episodes of hypoglycaemia. A modified reversal of the RYGB was performed. Mixed meal tests were done perorally (PO), through the gastrostomy tube 1 (GT1), 4 weeks (GT2) after placement and 4 weeks after reversal (POr), with assessment of glucose, insulin and GLP-1 levels.Plasma-glucose increased to a maximum of 9.6, 5.4, 6.5 and 5.8mmol/l at the PO, GT1, GT2 and POr tests respectively. The corresponding insulin levels were 2939, 731, 725 and 463pmol/l. A decrease of plasma-glucose followed: 2.2, 3.0, 3.9 and 2.9mmol/l respectively and insulin levels were suppressed at 150min: 45, 22, 21 and 14pmol/l, respectively. GLP-1 levels increased in the PO test (60min: 122pmol/l, 21 fold of basal), but was attenuated in the two latter tests (12-23pmol/l at 60min).Reduction of plasma-glucose, insulin and GLP-1 excursions and symptoms were seen after gastric tube placement and partial RYGB reversal. This attenuation of GLP-1 response to feeding could reflect an adaptation to nutrients

Micronutrient Supplementation after Biliopancreatic Diversion with Duodenal Switch in the Long Term

Background Malabsorptive bariatric surgery requires lifelongmicronutrientsupplementation.Basedontherecommendations, we assessed the number of adjustments of micronutrientsupplementationandtheprevalenceofvitaminandmineral deficiencies at a minimum follow-up of 5 years after biliopancreatic diversion with duodenal switch (BPD-DS). Methods Between October 2010 and December 2013, a total of 51 patients at a minimum follow-up of 5 years after BPDDS were invited for a clinical check-up with a nutritional blood screening test for vitamins and minerals. Results Forty-three of fifty-one patients (84.3 %) completed the blood sampling with a median follow-up of 71.2 (range 60–102) monthsafter BPD-DS. At that time,all patientswere supplemented with at least one multivitamin. However, 35 patients (81.4 %) showed either a vitamin or a mineral deficiencyoracombinationofit.Nineteenpatients(44.1%)were anemic,and17patients(39.5%)hadanirondeficiency.High deficiency rates for fat-soluble vitamins were also present in 23.2 % for vitamin A, in 76.7 % for vitamin D, in 7.0 % for vitamin E, and in 11.6 % for vitamin K. Conclusions Theresultsofourstudyshowthattheprevalence ofvitaminandmineraldeficienciesafterBPD-DSis81.4%at a minimum follow-up of 5 years. The initial prescription of micronutrientsupplementationandfurtheradjustmentsduring thefirstfollow-upwereinsufficient toavoidlong-term micronutrient deficiencies. Life-long monitoring of micronutrients at a specialized bariatric center and possibly a better micronutrient supplementation, is crucial to avoid a deficient micronutrient status at every stage after malabsorptive bariatric surger
