ABSTRACT
BACKGROUND: Single anastomosis sleeve ileal (SASI) bypass is a modification of sleeve gastrectomy with transit bipartition (SG + TB). This study aims to assess the safety and efficacy of SASI as a primary metabolic and bariatric surgery (MBS). METHODS: This is a retrospective case series of 30 patients who underwent SASI bypass from January to December 2021. All patients completed at least 12 months of follow-up. RESULTS: Among the 30 patients, 93.3% were women, the mean age was 37.4 years, and the mean body mass index (BMI) was 45.6 kg/m2. The percentage of total body weight loss (TWL%) was 42.7%, the percent excess body weight loss (EWL%) was 92.7%, and the mean BMI at 12 months went from 45.6(35.2-58.4) to 25.8 kg/m2 (19.2-33.4). The obesity-associated complications remission rate was 87.5% for type 2 diabetes (T2D), 71.4% for hypertension (HTN) and 100% for obstructive sleep apnea (OSA). Thirteen patients (43.3%) had diarrhea, 7 (23.3%) had hypoalbuminemia, defined as serum albumin < 3 g/dl, and 6 (20%) underwent reversal of their index SASI. As for other nutritional issues, iron deficiency anemia was present in 21 patients (70%), while 19 patients (63.3%) had vitamin D, and 2(6.6%) had vitamin B12 deficiency. CONCLUSION: Despite good short-term weight loss and improvement of obesity-associated complications, SASI is accompanied by high alarming malnutrition, even in short-term follow-up. Novel MBS should be judged for their long-term effects and compared to well-tested standard operations before they are used in routine clinical practice.

BACKGROUND: Malnutrition and liver impairment after duodenal switch (DS) are possible and undesired complications, often conservatively treated. However, in specific cases, surgical revision may be necessary. This study aims to describe outcomes achieved by two bariatric surgery centers and address effectiveness and safety of revisional surgical procedures to resolve these complications. METHODS: A retrospective chart review was performed in two bariatric surgery centers from 2008 to 2022. Patients who required revisional surgery to treat malnutrition and/or liver impairment refractory to nutritional and total parenteral nutrition intervention (TPN) after duodenal switch were included. No comparisons were performed due to the descriptive nature of this study. RESULTS: Thirteen patients underwent revisional surgery, the mean age was 44.7, the 53.8% were females, and the mean preoperative BMI was 54.7 kg/m2; the mean time between DS and revisional procedure was 26.5 months, and 69.1% of patients were placed on TPN. One patient developed hepatic encephalopathy; one patient presented with ascites, pleural effusion, and renal insufficiency, undergoing reoperation after revisional procedure due to a perforated ileal loop. Mortality rate was 0%; all patients regained weight after the revisional procedure, and the mean total protein and albumin blood levels 12 months after surgery were 6.3 and 3.6 g/dl, respectively. CONCLUSIONS: While refractory malnutrition and/or liver failure are rare among patients post-DS, if underdiagnosed and untreated, this can lead to irreversible outcomes and death. All revisional procedures included in this study resulted in improvement of the nutritional status and reversal of liver impairment, with low complication rates.

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: One of the hallmarks of frailty in patients with severe aortic stenosis (AS) is malnutrition, for which one of the most up-to-date scoring systems is the Naples prognostic score (NPS). This study sought to investigate the predictive role of the NPS in determining mortality in patients undergoing transcatheter aortic valve replacement (TAVR) under long-term follow-up. METHODS: A total of 430 consecutive patients with symptomatic severe AS who underwent TAVR were included retrospectively. The primary endpoint of the study was the long-term all-cause mortality. The study population was divided into two groups according to the NPS value, including Group 1 (NPS 0-2) and Group 2 (NPS 3-4). RESULTS: The all-cause mortality occurred in 250 patients (62.5%) patients during a follow-up time of 40.6 (22.0-69.4) months. During the follow-up period, all-cause mortality was higher in Group 2 compared with Group 1 (87.9% vs. 42.9%, p < 0.001). Older age (p < 0.001), chronic obstructive pulmonary disease (p = 0.015), left ventricular ejection fraction (p = 0.021), and being in Group 2 (high NPS) (hazard ratio: 7.058, 95% confidence interval: 5.174-9.629, p < 0.001) were found to be independent predictors of all-cause mortality at long-term follow-up. CONCLUSION: The NPS as a malnutrition and inflammation marker in patients with severe aortic stenosis who underwent TAVR provides valuable information for all-cause mortality under long-term follow-up.

Severe malnutrition following one-anastomosis gastric bypass (OAGB) remains a concern. Fifty studies involving 49,991 patients were included in this review. In-hospital treatment for severe malnutrition was needed for 0.9% (n = 446) of patients. Biliopancreatic limb (BPL) length was 150 cm in five (1.1%) patients, > 150 cm in 151 (33.9%), and not reported in 290 (65%) patients. OAGB was revised to normal anatomy in 126 (28.2%), sleeve gastrectomy in 46 (10.3%), Roux-en-Y gastric bypass in 41 (9.2%), and shortening of BPL length in 17 (3.8%) patients. One hundred fifty-one (33.8%) patients responded to treatment; ten (2.2%) did not respond and was not reported in 285 (63.9%) patients. Eight (0.02%) deaths were reported. Standardisation of the OAGB technique along with robust prospective data collection is required to understand this serious problem.

BACKGROUND: Two-stage revision remains the gold standard for periprosthetic joint infection (PJI) treatment. Although previous studies have examined malnutrition and frailty independently, their cumulative effects are not clear. Therefore, this study aimed to assess the individual and combined influence of malnutrition and frailty on the two-stage revision surgery. METHODS: Patients with chronic PJI undergoing two-stage revision were retrospectively included. The definition of PJI is completely consistent with the evidence-based definition of PJI recorded by the MSIS in 2018. Preoperative serum albumin levels and 11-item modified frailty index scores were collected. Four cohorts were created: (1) Normal (N), (2) Frail (F), (3) Malnourished (M), and (4) Malnourished and frail (MF). Demographic data, comorbidities, and postoperative complications were collected and compared between the four cohorts. RESULTS: A total of 117 consecutive patients were enrolled, 48% of patients were healthy (27.4% F, 16.2% M, and 9.4% MF). MF group showed lower scores on the physical composite scale of the 12-item short-form health survey (SF12-PCS), mental composite summary (SF12-MCS), Harris hip score (HHS), and knee society score (KSS) (P < 0.05). The incidence of reinfection in the MF group was higher than that in all other groups (MF vs. N; odds ratio [OR] 3.7, 95% confidence interval [CI] 1.37 - 8.82, P = 0.032). The incidence of complications in the MF group was higher than that in all other groups (MF vs. N; OR 4.81, 95% CI 1.58-9.26, P = 0.018). Postoperative transfusion events (OR 2.92, 95% CI 1.27-3.09, P = 0.021), readmission at 60 days after the operation (OR 4.91, 95% CI 1.82-13.80, P = 0.012) was higher in the MF patients. In addition, the extended length of stay after the operation was highest in the MF patients, with an OR of 5.78 (95% CI 2.16-12.04, P = 0.003). CONCLUSION: The concurrent presence of concomitant malnutrition and frailty in patients with PJI is related to poor prognosis and may be a predictor of the efficacy of two-stage revision. Future research will be needed to describe the benefits of improving these risk factors for patients with PJI.

INTRODUCTION: The role of the common channel length in duodenal switch (DS) on remission of type II diabetes mellitus (DM), when stratifying patients based on diabetes severity, is not well understood. METHODS: We retrospectively reviewed 341 consecutive patients with DM undergoing DS with one of three different common channel (CC) lengths (100 cm, 150 cm, and 200 cm), each with a fixed 300 cm alimentary limb (AL). Patients were stratified by insulin dependence (IDDM) versus non-insulin dependent diabetes (NIDDM). Data was collected at one year and at the last available follow-up. RESULTS: The NIDDM group had a similar average HbA1c at last follow-up for each of the CC lengths. However, the IDDM group had lower average HbA1c with shorter CC lengths (100 cm = 5.4%, 150 cm = 6%, 200 cm = 6.4%, p < 0.05). Shorter CC lengths resulted in a greater proportion of patients achieving remission in the IDDM group (66%, 50%, 32% in the 100 cm, 150 cm, and 200 cm CC, respectively, p < 0.01). Improvements in HbA1c were independent of weight loss and average DiaRem scores were similar between CC lengths. Rates of nutritional deficiencies were higher in shorter common channel lengths. Revision for malnutrition was similar between common channel lengths (100 cm group: 3.7%; 150 cm group: 1.8%; 200 cm group: 0%, p = NS). CONCLUSIONS: When the AL is fixed, shortening CC lengths results in improved glycemic control and remission of DM in patients with the need for insulin preoperatively. Milder forms of DM are treated well with any of the CC lengths.

PURPOSE: Malnutrition is a potentially modifiable risk factor of periprosthetic joint infection (PJI). The purpose of this study was to analyze the role of nutritional status as a risk factor for failure after one- stage revision hip or knee arthroplasty for PJI. METHODS: Retrospective, single-center, case-control study. Patients with PJI according to the 2018 International Consensus Meeting criteria were evaluated. Minimum follow-up was 4 years. Total lymphocyte count (TLC), albumin values, hemoglobin, C-reactive protein, white blood cell (WBC) count and glucose levels were analyzed. An analysis was also made of the index of malnutrition. Malnutrition was defined as serum albumin < 3.5 g/dL and TLC < 1500/mm3. Septic failure was defined as the presence of local or systemic symptoms of infection and the need of further surgery as a result of persistent PJI. RESULTS: No significant differences were found between increased failure rates after a one-stage revision hip or knee arthroplasty for PJI and TLC, hemoglobin level, WBC count, glucose levels, or malnutrition. Albumin and C-reactive protein values were found to have a positive and significant relationship with failure (p < 0.05). Multivariate logistic regression identified only hypoalbuminemia (serum albumin < 3.5 g/dL) (OR 5.64, 95% CI 1.26-25.18, p = 0.023) as a significant independent risk factor for failure. The receiver operating characteristic (ROC) curve for the model yielded an area under the curve of 0.67. CONCLUSION: TLC, hemoglobin; WBC count; glucose levels; and malnutrition, understood as the combination of albumin and TLC, were not found to be statically significant risk factors for failure after single-stage revision for PJI. However, albumin < 3.5 g/dL, alone was a statically significant risk factor for failure after single-stage revision for PJI. As hypoalbuminemia seems to influence the failure rate, it is advisable to measure albumin levels in preoperative workups.

BACKGROUND: Bariatric surgery (BS) can lead to postoperative nutritional deficiencies (NDs) due to restrictive and malabsorptive mechanisms, but there is limited literature quantifying NDs' prevalence over time and their predictors among patients undergoing BS. OBJECTIVE: To characterize time trends and predictors of postoperative NDs. SETTING: This retrospective cohort study used the U.S. IBM MarketScan commercial claims database (2005-2019) to include adults who underwent BS with continuous enrollment. METHODS: BS included Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), adjustable gastric band (AGB), and biliopancreatic diversion with duodenal switch. NDs included protein malnutrition, deficiencies in vitamins D and B12, and anemia that may be related to NDs. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of NDs across BS types after adjusting for other patient factors. RESULTS: Within 83,635 patients (mean age [SD], 44.5 [9.5] yr; 78% female patients), 38.7%, 32.9%, and 28% underwent RYGB, SG, and AGB, respectively. Age-adjusted prevalence of any NDs within 1, 2, and 3 years after BS ranged from 23%, 34%, and 42%, respectively (in 2006) to 44%, 54%, and 61%, respectively (in 2016). Relative to the AGB group, the adjusted OR of any 3-year postoperative NDs was 3.00 (95% CI, 2.89-3.11) for the RYGB group and 2.42 (95% CI, 2.33-2.51) for the SG group. CONCLUSIONS: RYGB and SG were associated with 2.4- to 3.0-fold odds of developing 3-year postoperative NDs compared with AGB, independent of baseline ND status. Pre- and postoperative nutritional assessments are recommended for all patients undergoing BS to optimize postoperative outcomes.

INTRODUCTION: Single anastomosis sleeve ileal bypass (SASI) is a combined bariatric metabolic technique, in which few studies have shown its outcomes efficacy. However, this technique has a high risk of malnutrition due to long biliopancreatic limb. Single anastomosis sleeve jejunal bypass (SASJ) has a shorter limb. Therefore, it seems to have a lower risk of nutrient deficiency. Furthermore, this technique is relatively new, and little is known about the efficacy and safety of SASJ. We aim to report our mid-term follow-up of SASJ from a high-volume center for bariatric metabolic surgery in the Middle East region. METHODS: For the current study, the 18-month follow-up data of 43 patients with severe obesity who underwent SASJ was collected. The primary outcome measures were demographic data, weight change variables according to ideal body mass index (BMI) of 25 kg/m2 at 6, 12, and 18 months, laboratory assessments, remission of obesity-associated medical problems, and other potential bariatric metabolic complications after the surgery. RESULTS: No patient was lost due to follow-up. After 18 months, patients lost 43.4 ± 11 kg of their weight and 68 ± 14% of their excess weight, and their BMI decreased from 44.9 ± 4.7 to 28.6 ± 3.8 kg/m2 (p < 0.001). The percentage of total weight loss till 18 months was 36.3%. The T2D remission rate at 18 months was 100%. Patients neither faced deficiency in significant markers for nutrition state nor represented major bariatric metabolic surgery complications. CONCLUSION: SASJ bypass achieved satisfactory weight loss and remissions in obesity-associated medical problems within 18 months after surgery without major complications and malnutrition.

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.

BACKGROUND: Malnutrition after bariatric operation is a rare but potentially life-threatening complication. The safety and efficacy of revisional bariatric operation in malnourished patients are not well elucidated. STUDY DESIGN: We performed a retrospective chart review of patients who underwent revisional bariatric operation for severe malnutrition at our institution between 2008 and 2020. Associations of demographic and clinical characteristics with dichotomous outcomes of interest were examined using Fisher's exact tests, Cochran-Armitage tests for trend, and two-sample t -tests when appropriate. RESULTS: Fifty-three patients underwent revisional bariatric operation for malnutrition from 2008 and 2020. The median follow-up was 24 months. The anatomy before revision was Roux-en-Y gastric bypass (n = 40, 75%), biliopancreatic diversion with duodenal switch (n = 6, 11%), sleeve gastrectomy (n = 4, 8%), and mini gastric bypass (n = 3, 6%). The percentage of patients requiring supplemental or total nutritional support decreased from 89% preoperatively (47% on enteral feedings and 42% on total parenteral nutrition (TPN) with or without tube feeding) to 13.2% at the last encounter after revision (7.5% still requiring enteral feedings and 5.7% on TPN). There was an association between the number of prior abdominal operations and postoperative pneumonia (p 0.03) and need for blood transfusion (p 0.01). There were no associations between major complications or last encounter nutrition and any preoperative variables other than age at the time of operation. There were 2 mortalities during a median follow-up of 24 months, and both occurred more than 1 year postoperatively. CONCLUSION: Revisional operation for severely malnourished bariatric operation patients is effective in the discontinuation of supportive nutrition. Postoperative complications are increased but not prohibitive.

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.

BACKGROUND: Santoro's operation is a sleeve gastrectomy with transit bipartition. The operation aims to maintain passage to the duodenum to minimize nutritional deficiency. This procedure is rapidly changed to single anastomosis sleeve ileal (SASI) bypass. SAS-J bypass is a modification of SASI with a short biliary limb. MATERIAL AND METHODS: This study is a retrospective study of prospectively collected data. The study includes a comprehensive review of 1986 patients who underwent SAS-J bypass over 6 years. The total number is used to evaluate the perioperative data. One- and two-year follow-up was used to evaluate weight loss and comorbidities; follow-up of more than 5 years was used to obtain long-term results. RESULTS: In this study, 70.4% of patients were female and 29.6% were male. The mean body mass index (BMI) was 44.7. The mean age was 42 years. Regarding comorbidities, 25.8% of the patients had type 2 diabetes, 31% were hypertensive, 14.2% had sleep apnea syndrome, 6.6% had gastroesophageal reflux disease (GERD), and 39.6% had hyperlipidemia. Of the 1294 patients who complete one-year follow up, %EWL reached 87%. Blood glucose levels were normalized in 98.5% of patients, hypertension remitted in 93%, hyperlipidemia improved in 97%, SAS is improved in all cases, and GERD improved in 89% of patients. After 5 years, 94 patients' BMI decreased from 44.3 to 28.3 without significant nutritional deficiency. CONCLUSIONS: Laparoscopic SAS-J bypass is an effective and simple alternative bariatric procedure at short- and long-term follow-up.

OBJECTIVES: To understand the prevalence of malnutrition and its association with chronic limb-threatening ischemia (CLTI) outcomes; to clarify the differential impact of revascularization methods on outcomes; to assess the ability of the CLTI Frailty Risk Score (CLTI-FRS) to predict adverse events in patients hospitalized with CLTI. BACKGROUND: Despite advances in the management of CLTI, a majority still undergo major amputation, and a minority heal within 6 months. There is a lack of validated assessment tools for the identification and management of frailty and malnutrition in these patients. METHODS: Using the National Inpatient Sample from January 2012 to September 2015, we identified all patients with CLTI using International Classification of Diseases Ninth Edition Clinical Modification codes. The cohort was divided into three groups according to nutritional status. Multivariable regression analysis was used to analyze the interaction between malnutrition and outcomes of interest. RESULTS: Of 1,414,080 CLTI-related hospitalizations, 163,835 (11.6%) were malnourished, 332,855 (23.5%) patients were frail, 917,390 (64.9%) were well-nourished. In-hospital mortality, major amputation, the average length of stay, and hospital costs were highest among malnourished or frail patients and lowest in well-nourished patients (p < 0.001). Malnourished and frail patients were observed to have lower rates of mortality with endovascular revascularization as compared to surgical (adjusted odds ratios: 0.675 [0.533-0.854; p = 0.001]). CONCLUSION: Many patients with CLTI are malnourished or frail, and this is associated with mortality and amputation. Both malnourished and frail patients were observed to have a mortality benefit with a less invasive approach to revascularization. Better assessment of nutritional and frailty status of CLTI patients may guide therapy and help prevent amputation and death.

BACKGROUND: Gastroparesis (GP) is a rare condition for which several symptomatic treatments are available, but they may fail, leading to a discussion of gastrectomy. Few studies have described gastric-preserving surgery, particularly in malnourished patients. OBJECTIVE: To describe the treatment of severe refractory GP with Roux-en-Y gastric bypass (RYGB). SETTING: A university center. METHODS: A retrospective review was conducted of adult patients who underwent laparoscopic RYGB. Severity and frequency of GP symptoms were compared before and 1 year after surgery using the Gastroparesis Cardinal Symptom Index (GCSI) score (0-5), the vomiting (VM) score (0-4), and the visual analog scale (VAS) for abdominal pain. RESULTS: Of the 9 patients with refractory GP, 7 were malnourished and 2 had obesity. There were no postoperative deaths. One patient was operated on for internal hernia without bowel necrosis. The mean GCSI score decreased significantly from 3.6 (range: 1-5) preoperatively to 2.1 (range: .3-4.4) postoperatively (P = .0019). The mean VM score improved significantly after surgery, from .22 (range: 0-1 units) preoperatively to 2.55 (range: 1-4) postoperatively (P = .007). The mean VAS score also decreased significantly from 7.0 (range: 5-9) preoperatively to 2.44 (range: 0-7) postoperatively (P = .0015). A nonsignificant weight and albumin change was observed at 1 year postoperatively, with a tendency for weight regain in malnourished patients. CONCLUSION: In malnourished patients with severe and refractory GP, this study suggests the feasibility, safety, and efficacy of RYGB for the treatment of vomiting and abdominal pain.

OBJECTIVE: Single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S) is a powerful form of bariatric surgery; however, it has a high risk of malnutrition. Single anastomosis sleeve ileal (SASI) bypass with sleeve gastrectomy may be used as an alternative procedure to avoid malnutrition associated with SADI-S; however, no comparison between the two procedures has been performed. METHODS: Sprague-Dawley rats with diabetes (n = 32) were divided into four groups: SADI-S (n = 8), SASI (n = 8), SG (n = 8), and SHAM (n = 8). Body weight, food intake, and fasting blood glucose were measured, and the oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed before and after surgery. Blood samples were collected before and after the surgery to assess the levels of glucagon-like peptide-1 (GLP-1), hemoglobin, albumin, vitamin B12, calcium, and iron. RESULTS: The SADI-S and SASI groups showed significantly greater weight loss and better glucose control than the SG group postoperatively. The SADI-S and SASI groups showed similar improvements in glucose control throughout the study. The SADI-S and SASI groups had significantly higher GLP-1 levels than the SG group at 6 months. The SADI-S and SASI groups presented with various degrees of deficiencies, with the SADI-S group showing a higher risk for hypoalbuminemia and iron deficiency than the SASI group. CONCLUSIONS: The SASI procedure may be a better alternative as it has excellent bariatric and metabolic results with lower risk for hypoalbuminemia and can be easily converted into either SADI-S or SG procedures. Nevertheless, further clinical results are needed.

OBJECTIVE: The objective of this study was to evaluate, through multivariate analysis, the configuration of nutritional predictors that impact the development pharyngocutaneous fistula (PCF) after total laryngectomy. METHODS: A retrospective cohort study carried out on 203 consecutive patients with laryngeal squamous cell carcinoma who underwent total laryngectomy with neck dissection between June 2015 and June 2020. Patients with risk factors for PCF formation, other than malnutrition, were excluded to eliminate the potential impact of that risk factors on PCF formation and to make the study group homogenous. Five parameters were evaluated including preoperative serum prealbumin, albumin and transferrin levels, Body Mass Index (BMI) and Malnutrition Screening Tool (MST). RESULTS: Univariate analysis revealed that preoperative prealbumin, albumin and transferrin levels significantly correlated with PCF development. Multivariate logistic regression analysis revealed that preoperative prealbumin level was the best independent nutritional predictor of PCF (P value <0.001, odd ratio 11.951 [95% CI 3.686-38.749]) followed by preoperative albumin (P value 0.006, odd ratio 3.985 [95% CI 1.485- 10.694]). CONCLUSION: Preoperative prealbumin level is considered the best independent nutritional predictor of PCF. It should be used to evaluate the nutritional status of patients undergoing total laryngectomy and hence their need for nutritional support.

STUDY DESIGN: Retrospective longitudinal cohort study. OBJECTIVE: To investigate postoperative medical complications in patients with malnutrition after cervical posterior surgery. METHODS: A total of 256 patients were participated and divided into PNI < 50 group (group L) or PNI ≥ 50 (group H). Patient data, preoperative laboratory data, surgical data, hospitalization data, JOA score, complication data were measured. RESULTS: Group L and group H were 127 and 129 patients, each PNI was L: 44.8 ± 4.3, H: 54.6 ± 4.0, P < 0.01. There was significant difference in mean age (L: 72.2 years vs H: 64.8 years, P < 0.01), BMI (23.1 vs 24.7, P < 0.01), serum albumin (L: 3.9 ± 0.4 g/dl vs H: 4.4 ± 0.3 g/dl, P < 0.01), total lymphocyte count (L: 1.3 ± 0.5 103/µL vs H: 2.1 ± 0.7 103/µL, P < 0.01), hospital stay (L: 25.0 days vs H: 18.8 days, P < 0.05), discharge to home (87.5% vs 57.5%, P < 0.01), delirium (L: 15.9% vs H: 3.9%, P < 0.01), medical complications (L: 25.2% vs H: 7.0%, P < 0.01), pre- and post- operative JOA score (L: 11.3 ± 2.8 vs H: 12.4 ± 2.6, P < 0.01; L: 13.3 ± 3.0 vs H: 14.1 ± 2.4, P = 0.02). Multiple logistic regression analysis showed that significant risk factors for medical complications were PNI<50 (P = 0.024, odds ratio [OR] 2.746, 95% confidence interval [CI] 1.143-6.600) and age (P = 0.005, odds ratio [OR] 1.064, 95% confidence interval [CI] 1.020-1.111). CONCLUSION: Medical complications are significantly higher in patients with PNI < 50 and higher age. The results showed that PNI is a good indicator for perioperative medical complications in cervical posterior surgery. Improvement of preoperative nutritional status is important to avoid medical complications. LEVEL OF EVIDENCE: 3.
