ABSTRACT
BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD-DS) is the most effective and durable metabolic and bariatric surgery to achieve a target weight loss. However, many surgeons are hesitant to adopt BPD-DS due to a lack of training, technical complexity, and long-term nutrition deficiencies. This meta-analysis aimed to investigate long-term nutrition outcomes after primary BPD-DS in the management of obesity. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles from their inception to February 2023 by 2 independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42023391316). RESULTS: From 834 studies screened, 8 studies met the eligibility criteria, with a total of 3443 patients with obesity undergoing primary BPD-DS. At long-term follow-up (≥5 years), 25.4% of patients had vitamin A deficiency (95% CI: -.012, .520, I2 = 94%), and 57.3% had vitamin D deficiency (95% CI: .059, 1.086, I2 = 86%). Calcium deficiency was observed in 125 patients (22.2%, 95% CI: .061, .383, I2 = 97%), and 69.7% had an abnormal parathyroid hormone level (95% CI: .548, .847, I2 = 78%). Ferritin level was abnormal in 30 patients (29.0%, 95% CI: .099, .481, I2 = 79%). CONCLUSIONS: Despite displaying comparable nutrition-related outcomes to mid-term follow-up, our study demonstrated that BPD-DS could result in a high level of long-term nutrition deficiency after BPD-DS for selected patients. However, further randomized controlled studies with standardized supplementation regimens and improvement in compliance are necessary to evaluate and prevent long-term nutritional deficiencies after BPD-DS.

BACKGROUND: Weight loss failure or weight regain may occur after Roux-en-Y gastric bypass (RYGB). Revisional surgery includes distalization. However, few studies have looked at the associations between the total alimentary limb length (TALL) and weight loss outcomes, none with long-term results. OBJECTIVES: Peri- and postoperative outcomes were assessed after employing TALL of either 250 cm or 300 cm in the failed RYGB. METHODS: This study is a retrospective cohort analysis of 90 patients that underwent laparoscopic distalization between January 2006 and January 2016 due to failed RYBG. The index RYGB was modified to TALL of 250 cm (n = 48) or of 300 cm (n = 42) which entailed elongating the bilio-pancreatic limb (BPL) and transposing the Roux limb (RL) to a common limb (CL) of 100 cm and 150 cm, respectively. Long-term weight loss outcomes along with nutritional and vitamin status were analyzed. RESULTS: Preoperative BMI at distalization was 38.6 kg/m2. After 8 years, excess weight loss (EWL) was 61.8%. No differences between the two groups were seen in weight loss outcomes or early surgical complication rates (6.7%). However, more vitamin and nutritional deficiencies were present in the TALL 250-cm group (50.0% and 35.4%, respectively) versus the TALL 300-cm group (33.3% and 14.3% respectively), which led to laparoscopic revision in 27 patients by lengthening the TALL with 100 cm. Patients with weight regain after index RYGB had in average 59.9% higher EWL than patients with EWL failure. CONCLUSION: Distalization of the failed RYGBP is safe and effective, but TALL should not be shorter than 300 cm (and CL 150 cm) due to high rates of malnutrition. Adequate supplementation and long-term follow-up are mandatory to prevent serious malnutrition.

PURPOSE: Lifelong daily multivitamin supplementation is highly recommended after sleeve gastrectomy (SG). Based on previous research, a specialized multivitamin supplement (MVS) for SG patients was developed and optimized (WLS Optimum 1.0 and 2.0). This study presents its mid-term effectives and compares micronutrient status of SG patients using this specialized MVS to users of standard MVS (sMVS) and non-users of multivitamin supplementation during the first three years post-surgery. MATERIALS AND METHODS: Of the 226 participants that were included at baseline, yearly follow-up blood tests were completed by 193 participants (85%) at 12 months, 176 participants (78%) at 24 months, and 140 participants (62%) at 36 months of follow-up. At each time point, participants were divided into four groups: (1) Optimum 1.0, (2) Optimum 2.0, (3) sMVS, and (4) non-users. Serum concentrations (linear mixed-effects models) and the prevalence of micronutrient deficiencies (chi-square tests) during follow-up were compared between the groups. RESULTS: Users of specialized MVS (Optimum 1.0 and 2.0) had higher serum concentrations of hemoglobin, folic acid, and vitamin D compared to sMVS users and non-users during follow-up. Serum concentrations of vitamin B12 and (corrected) calcium were also higher in specialized MVS users than in non-users. Overall, fewer deficiencies for folic acid and vitamin D were observed in the Optimum groups. CONCLUSION: Although the perfect multivitamin supplement for all SG patients does not exist, WLS Optimum was more effective in sustaining normal serum concentrations than standard, over-the-counter supplementation. Non-users of MVS presented with most micronutrient deficiencies and will evidently develop poor nutritional status on the longer term.

OBJECTIVE: This study is aimed at determining the preoperative nutritional status of patients with hepatic alveolar echinococcosis (HAE), and subsequently establish a concise and reasonable nutritional evaluation indicator. The established evaluation method could be used for clinical preoperative risk assessment and prediction of post-operation recovery. METHODS: The basic patient information on height, body weight, BMI and hepatic encephalopathy of 93 HAE patients were examined. Subsequently, abdominal ultrasonography, blood coagulation and liver function tests were done on the patients. Liver function was assessed using the Child-Pugh improved grading method while nutritional status was evaluated using the European Nutrition Risk Screening 2002 (NRS 2002) method. Additional parameters including hospitalization time, the hemoglobin (HGB) level on the 3rd day after the operation, and the number of postoperative complications of HAE patients were also recorded. RESULTS: The NRS 2002 score was negatively correlated with body weight, body mass index (BMI)and albumin (ALB) (P<0.01), and positively correlated with the transverse and longitudinal diameters of the lesions (P<0.01). A worse grading of liver function was associated with a low ALB and a high NRS 2002 score (P<0.01). Results of the NRS 2002 score indicate that the hospitalization time of the normal nutrition group was significantly shorter than that of the malnourished group (P < 0.05). The HGB level of the control group on the 3rd day after the operation was significantly higher than that of the malnourished group (P < 0.05), and the number of postoperative complications was lower than that of malnutrition group (P < 0.05). CONCLUSION: Malnutrition is common in HAE patients. The nutritional status of HAE patients is related to many clinical factors, such as Child-Pugh classification of liver function, size of the lesion, and ALB among others. Although both BMI and ALB can be used as primary screening indicators for malnutrition in HAE patients, NRS 2002 is more reliable and prudent in judging malnutrition in HAE patients. Therefore, BMI and ALB are more suitable for preoperative risk assessment and prediction of postoperative recovery.

BACKGROUND: Despite the success of the Biliopancreatic Diversion with Duodenal Switch procedure (BPD-DS) in weight loss and comorbidities resolution, reversal of BPD-DS is necessary in 0.2-0.6% of BPD-DS cases for vitamin, protein, and other micronutrient deficiencies. Different techniques are available to reverse the malabsorptive component of the BPD-DS. METHODS: A retrospective chart review for a 37-year-old female patient who presented with lower leg edema and signs of malnutrition 5 years after a BPD/DS. The patient was not compliant with the required daily vitamin and protein intake. Thus, after extensive discussion with the patient, a decision was made to reverse the malabsorptive component of the BPD-DS. RESULTS: A laparoscopic reversal of the malabsorptive component of the BPD-DS was concluded by transecting the roux limb distally at the ileo-ileal anastomosis and reconnecting it to the proximal jejunum thus substantially lengthening the common channel for absorption. At 6 months follow-up, the patient normalized her vitamin deficiency and had a normal level of serum protein. Her weight, BMI, EWL%, and TBWL% were 72 kg, 27.5 kg/m2, 90%, and 45%, respectively. CONCLUSIONS: Proper nutrition and vitamin supplementation is essential to avoid nutritional complications. Different techniques are available to reverse the malabsorptive component of the BPD-DS. However, no standard approach is adopted by the surgical community. We demonstrate our preferred technique in reversing the malabsorptive component of the BPD-DS.

OBJECTIVE: Our aim was to determine the effect of hypoalbuminaemia as a marker of malnutrition on the 30-day postoperative complication rate and mortality in patients receiving surgical treatment for hip fractures using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. METHODS: We analyzed all patients admitted with hip fractures receiving surgical treatment from 2011 to 2013. Patients were dichotomized based on their albumin levels; hypoalbuminaemia (albumin <3.5g/dL), and nonhypoalbuminaemia (albumin >3.5g/dL). Patient demographics, postoperative complications, and length of stay were analysed. Logistic regression analysis was conducted to assess the ability of albumin level for predicting postoperative complications, length of stay, and mortality. RESULTS: A total of 10,117 patients with hip fractures were identified with 5414 patients with normal albumin levels, and 4703 with low albumin. Multivariate analysis showed that when controlling for comorbidities; hypoalbuminaemia alone was a predictor of postoperative complications (death, unplanned intubation, being on a ventilator >48h, sepsis, and blood transfusion), and increased length of stay (6.90±7.23 versus 8.44±8.70, CI 0.64-1.20, P<0.001). CONCLUSION: Hypoalbuminaemia alone can predict postoperative outcomes in patients with hip fractures. Furthermore, patients with hypoalbuminaemia had a longer hospital length of stay. Further studies are needed to assess whether nutritional support can improve postoperative complications in patients with hypoalbuminaemia.

Nutritional and metabolic complications can develop after Roux-en-Y gastric bypass (RYGB) when there is an exaggerated response to the anatomical and functional changes or when there is inadequate nutritional supplementation. Severe malnutrition is rare, but deficiencies of vitamin B12, iron, calcium and thiamin, metabolic bone disease and gallstones are common after RYGB. Shortage of vitamin B12, iron, calcium and also cholelithiasis are caused at least partially by excluding the duodenum and proximal jejunum from food transit. We designed a new procedure, with the maintenance of the duodenum and proximal jejunum in the gastrointestinal transit through interposition of jejunal loop, as a primary operation to prevent such deficiencies or as corrective surgery for severe malnutrition after RYGB with failure in responding to conservative treatment. Complicações nutricionais e metabólicas podem se desenvolver após a derivação gástrica em Y de Roux (DGYR) quando há uma resposta exagerada às mudanças anatômicas e funcionais ou quando há suplementação nutricional inadequada. A desnutrição grave é rara, mas deficiências de vitamina B12, ferro, cálcio e tiamina, doença óssea metabólica e cálculos biliares são comuns após a DGYR. Dessas deficiências mencionadas, a de vitamina B12, de ferro, de cálcio e também a colelitíase, são causadas, ao menos parcialmente, pela exclusão do duodeno e jejuno proximal. Um novo procedimento com a manutenção do duodeno e do jejuno proximal no trânsito gastrointestinal, mediante interposição de alça jejunal, foi idealizado como operação primária para prevenir essas deficiências ou como cirurgia corretiva de desnutrição grave após DGYR com falha na resposta a exaustivas tentativas de tratamento conservador.
