Introduction: Various techniques and reinforcements have been proposed over the years in order to prevent leaks and bleeding after sleeve gastrectomy (LSG). The aim of this study was to retrospectively compare the staple line complication (SLC) rate in patients who underwent LSG with the use of bioabsorbable membrane (GORE® SEAMGUARD®, GoR) for staple line versus those who received no reinforcement. Methods: Data on all consecutive patients undergoing LSG between 1 January 2014 and 31 December 2018 were retrospectively reviewed. Patients were divided into two groups: the GoR+ group if the SeamGuard (GoR) was used and the GoR- group if no reinforcement was applied on the staple line. Preoperative demographics and rate of SLC were compared between groups. All cases of SLC coming from other centers were also reviewed. Results: A total number of 626 LSGs were performed at our institution during the study period. GoR was applied in 450 (71.9%) cases (GoR+ group), while NR was used in 176 (28.1%) patients (GoR- group). Two (1.13%) cases of leaking and two (1.13%) cases of bleeding occurred in the GoR- group, while no SLC was recorded in patients who received GoR (p < 0.05). Thirteen cases of SLC coming from other institutions were treated at our hospital; all these cases were performed without any SLR. Conclusion: In our case series, the use of GoR reduced the rate of SLC after LSG. In all cases of SLC coming from other institutions, no reinforcement had been applied on the staple line during LSG.

Obesity is a worldwide epidemic, and bariatric surgery is considered the primary treatment for long-term weight loss and managing obesity-related health issues. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most performed procedures. Nutritional deficiencies are a significant concern following bariatric surgery and can have serious consequences. This study aims to compare the incidence of nutritional deficiencies in patients undergoing RYGB and SG. A retrospective analysis was conducted on the nutritional status of 505 consecutive patients who underwent either RYGB or SG between January and December 2019. Data were collected regarding vitamin B12, folic acid, vitamin D, calcium, PTH, magnesium, hemoglobin, iron, ferritin, and transferrin at preoperative, 6-month, and 12-month intervals post-surgery. The RYGB group showed significantly higher excess weight loss. Vitamin B12, hemoglobin, and ferritin levels were consistently higher in the SG group throughout the study. Vitamin D deficiency was prevalent, with no significant difference between the groups. Vitamin B12 deficiency was significantly more common in the RYGB group (6 months: 17.46% vs. 4.69%, p < 0.001; 12 months: 16.74% vs. 0.93%, p < 0.001). Despite differences in their mechanisms, bariatric surgeries were associated with nutritional deficiencies. It is crucial to efficiently assess, prevent, and manage these deficiencies tailored to each surgical procedure.

OBJECTIVE: This study aimed to compare complication rates between pylorus-preserving gastrectomy (PPG) and distal gastrectomy (DG) using Korean nationwide survey data and propensity score weighting (PSW). PPG preserves gastric function but may lead to more postoperative complications than DG.
RESULTS: We analyzed 9424 gastric cancer patients who underwent either DG (n = 9183) or PPG (n = 241). PSW balanced variables such as age, sex, TNM stage, comorbidities, ASA score, and surgical approach. Before PSW, 87.8% of DG patients and 87.1% of PPG patients had no complications (p = 0.053). Severe complications (Clavien-Dindo IIIa or higher) were more frequent in PPG (6.6%) than in DG (3.8%) (p = 0.039). After PSW, overall complication rates (p = 0.960) and severe complication rates (p = 0.574) were similar between groups. Incidence rates of anastomotic stricture and leakage were higher in PPG (2.9% and 1.7%) compared to DG (0.6% and 0.5%) (p = 0.001 and 0.036) before PSW, but these differences were not significant after PSW (p = 0.999 and 0.123).
CONCLUSIONS: The PSW-adjusted analysis indicates no significant difference in overall and severe complication rates between PPG and DG in gastric cancer patients.

(1) Background: Alcohol consumption is one of the main causes of acute pancreatitis. (2) Material and Methods: In this unicentric retrospective cohort study, we selected 1855 patients from the Bucharest Acute Pancreatitis Index (BUC-API) who presented with acute pancreatitis. We investigated correlations between Alcoholic Acute Pancreatitis (AAP) and the rate of complications, cost, length of hospitalization and rate of recurrence. (3) Results: We found a moderately strong association between AAP and recurrence (p < 0.01) and observed that the disease is likelier to evolve with pseudocysts and walled-off necrosis than other forms of AP. Patients with AAP are less likely to have a morphologically normal pancreas than patients suffering from AP of other causes (p < 0.01), but a low probability of requiring intensive care unit admission (p < 0.01) significantly lowers daily cost (Md = 154.7 EUR compared to Md = 204.4 EUR) (p < 0.01). (4) Conclusions: This study\'s data show that patients with AAP have a greater rate of pseudocyst occurrence, lower intensive care unit admittance rate and lower cost of hospitalization than patients with AP of other causes. Typical Sketch: A middle-aged male tobacco smoker with recurrent AP, lower risk of in-hospital mortality and complications such as pseudocysts; treated in a gastroenterological ward and discharged at-will.

Roux-en-Y gastric bypass (RYGB) is a treatment for severe obesity. However, many patients have insufficient total weight loss (TWL) after RYGB. Although multiple factors have been involved, their influence is incompletely known. The aim of this exploratory study was to evaluate the feasibility and reliability of the use of machine learning (ML) techniques to estimate the success in weight loss after RYGP, based on clinical, anthropometric and biochemical data, in order to identify morbidly obese patients with poor weight responses. We retrospectively analyzed 118 patients, who underwent RYGB at the Hospital Clínico Universitario of Valencia (Spain) between 2013 and 2017. We applied a ML approach using local linear embedding (LLE) as a tool for the evaluation and classification of the main parameters in conjunction with evolutionary algorithms for the optimization and adjustment of the parameter model. The variables associated with one-year postoperative %TWL were obstructive sleep apnea, osteoarthritis, insulin treatment, preoperative weight, insulin resistance index, apolipoprotein A, uric acid, complement component 3, and vitamin B12. The model correctly classified 71.4% of subjects with TWL < 30% although 36.4% with TWL ≥ 30% were incorrectly classified as \"unsuccessful procedures\". The ML-model processed moderate discriminatory precision in the validation set. Thus, in severe obesity, ML-models can be useful to assist in the selection of patients before bariatric surgery.

BACKGROUND: Morbid obesity is a complex chronic condition characterized by a body mass index of 40 kg/m2 or higher. The incidence of the condition is on the rise in developed countries, and bariatric surgery has been proposed as a potential solution to address this trend. Nonetheless, bariatric surgery may also result in adverse effects, including a reduction in bone mineral density (BMD) and muscle mass, as well as an increased risk of fractures. The present study aims to elucidate the effects of bariatric surgery and whole-body vibration (WBV) training on body composition, microbiota, physical fitness, quality of life, and cardiometabolic markers.
METHODS: Twenty-eight participants (14 females), aged 18 to 50 years, will undergo sleeve gastrectomy surgery. They will be randomly allocated into a control group or a WBV training group. The WBV group will train three times per week with increasing intensities and duration ranging from 30 to 45 min over the 4-month training period. Measurements of body composition (dual-energy X-ray absorptiometry and peripheral quantitative computed tomography), physical fitness (muscular strength, agility, cardiorespiratory fitness, and balance), gait biomechanics, cardiometabolic markers, gut microbiota, quality of life, and physical activity levels will be collected at four different time points: (1) prior to the surgery, (2) 45 days post-surgery, (3) 6 months post-surgery, and (4) 18 months post-surgery.
CONCLUSIONS: Both groups are expected to experience improvements in most of the aforementioned variables. Nonetheless, we expect the WBV group to show larger improvements proving that the training is effective and safe.

Enhanced Recovery After Surgery (ERAS) protocols have changed perioperative care, aiming to optimize patient outcomes. This study assesses ERAS implementation effects on postoperative complications, length of hospital stay (LOS), and mortality in colorectal cancer (CRC) patients. A retrospective real-world analysis was conducted on CRC patients undergoing surgery within a Northern Italian Cancer Registry. Outcomes including complications, re-surgeries, 30-day readmission, mortality, and LOS were assessed in 2023, the year of ERAS protocol adoption, and compared with data from 2022. A total of 158 surgeries were performed, 77 cases in 2022 and 81 in 2023. In 2023, a lower incidence of postoperative complications was observed compared to that in 2022 (17.3% vs. 22.1%), despite treating a higher proportion of patients with unfavorable prognoses. However, rates of reoperations and readmissions within 30 days post-surgery increased in 2023. Mortality within 30 days remained consistent between the two groups. Patients diagnosed in 2023 experienced a statistically significant reduction in LOS compared to those in 2022 (mean: 5 vs. 8.1 days). ERAS protocols in CRC surgery yield reduced postoperative complications and shorter hospital stays, even in complex cases. Our study emphasizes ERAS\' role in enhancing surgical outcomes and recovery.

OBJECTIVE: We examined the association between Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) and fracture risk, including major osteoporotic fractures (MOF), and the use of anti-osteoporosis medication (AOM). While RYGB is associated with impaired bone health and increased fracture risk, it remains uncertain whether SG has a similar impact, and whether this risk is primarily due to MOF or any fracture.
METHODS: We conducted a nationwide cohort study covering patients treated with RYGB (n=16,121, 10.2 years follow-up) or SG (n=1,509, 3.7 years follow-up), from 2006-2018, comparing them to an age- and sex-matched cohort (n=407,580).
METHODS: We computed incidence rates and adjusted hazard ratios (HR) with 95% confidence intervals (CIs), using Cox regression for any fracture, MOF, and use of AOM with adjustment for comorbidities.
RESULTS: Compared to the general population cohort, RYGB was associated with an increased risk of any fracture (HR 1.56 [95% CI: 1.48; 1.64]) and MOF (HR 1.49 [1.35; 1.64]). SG was associated with an increased risk of any fracture (HR 1.38 [1.13; 1.68]), while the HR of MOF was 1.43 [0.97; 2.12]. The use of AOM was low but similar in all cohorts (approximately 1%).
CONCLUSIONS: Bariatric surgery increased the risk of any fracture and MOF to similar extend. Risks were similar for RYGB and SG. However, SG had a shorter follow-up than RYGB, and the cohort size was rather small. More research is needed for long-term SG fracture risk assessment. The use of AOM was low in all cohorts.

BACKGROUND: The three types of evidence-based treatment options for adults with overweight and obesity - behavioral weight management, anti-obesity medications (AOM), and bariatric surgery - are underutilized in the Veterans Health Administration (VHA) system. Our objective in this manuscript is to describe the study protocol for an adequately powered randomized controlled trial (RCT) of a behavioral intervention: TOTAL (Teaching Obesity Treatment Options to Adult Learners) to increase patient uptake of obesity treatment.
METHODS: In this multi-site, parallel, RCT, eligible Veterans with a body mass index [BMI] ≥ 27 who had not received obesity treatment within the past 12 months were randomly assigned to TOTAL or usual care. TOTAL involves watching an 18-min video that highlights obesity health risks, pros/cons of all three evidence-based obesity treatments, and expected treatment outcomes. It also includes motivational sessions delivered via televideo at 2 weeks, 6 months, and 12 months after the video (target n = 494 participants). The primary outcome is initiation of behavioral weight management treatment within 18 months of randomization. Secondary outcomes include sustained behavioral weight management treatment, initiation of AOM, bariatric surgery referral, and weight change across 18 months.
CONCLUSIONS: TOTAL, which seeks to increase delivery of weight management treatment within the largest integrated health system in the U.S., combines patient education with motivational interviewing components. If efficacious in this trial, further evaluation of intervention effectiveness and implementation throughout the VHA and other healthcare systems would be warranted.
