Abstract

Background
To support patients in their weight loss journey, it is important that healthcare professionals (HCPs) recognise their patient’s communication needs and adapt to them. This study looks at the health literacy and numeracy (HLN) of patients attending a bariatric outpatient clinic and the accuracy of HCPs’ estimations of patients’ HLN.

Method
Patients completed validated HLN measures—the Medical Term Recognition Test (METER) and General Health Numeracy Test Short Form (GHNT-6) and a demographics survey. HCPs provided an estimation of the patient’s HLN after their consultation based on the scoring categories of each measure. The score from the patient-completed measures and estimations from the HCP were compared.

Results
Data was collected from 31 patients attending clinic in a single tertiary centre. Based on METER, 80% of patients demonstrated functional health literacy and 7% low health literacy. There was poor agreement between HCPs estimations and measured health literacy (ICC = 0.14; 95% c.i. = -0.19, 0.443), with HCPs more likely to underestimate than overestimate patient’s health literacy (27.8% versus 11.1%). 61.1% of HCPs’ health literacy estimations agreed with METER categories. In the health numeracy measure 3.2% (n = 1) of participants answered all questions correctly, 22.6% of participants scored 0, and 19.4% (n = 6) answered the food label question correctly. There was poor agreement between HCP estimation and measured health numeracy (ICC = -0.196; c.i. = −0.487, 0.1360 P = 0.878), with HCPs more likely to overestimate than underestimate patients’ health numeracy (63.9% versus 22.2%). Only 13.9% of HCP health numeracy estimations agreed with GHNT-6 ratings.

Conclusion
There is poor agreement between HCPs’ perception of their patient’s HLN and patient’s assessed ability through a validated questionnaire. Health numeracy is a known barrier to understanding health-related information and is a demonstrated area for further development in this patient population. HCPs’ identification/appreciation of these is vital in supporting patients’ journeys through the challenging bariatric surgery pathway and postoperative course.
IBC Oxford University Oral Abstract 45 - Postoperative reduced oral feeding is a risk factor for lengthened period of hospital admission and readmission post bariatric surgery
Authors: Alhuniti M 
Published: February 2025

Abstract

Objectives
The revolution of the Laparoscopic bariatric techniques and improved postoperative recovery protocols and regimens have reduced hospital admissions, readmissions and stay; some patients continue to have prolonged admission for various reasons. This paper concentrates and explores whether postoperative oral feeding is a potential risk factor for lengthened hospitalization and readmission.

Methods
A prospective, double blinded, randomized investigation of 450 postoperative patients at King Hussein Hospital, King Hussein Medical City, Amman, Jordan, during the period March 2019–September 2023. Subjects (255 women and 195 men, aged 24–55, with an average of 36 years) were managed for morbid obesity, and were assigned to laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) groups. Subjects with perioperative hazards and previous bariatric techniques were ruled out. Early oral feeding (oral diet tolerance include solid food and drinking minimum of 1.5 l) with clear fluid on day zero associated with balanced intravenous fluids less than 2.5 l then light hospital diet on the first day after surgery and full hospital diet (solid and fluids) in the second day after surgery were encouraged included subjects with hospital admission (3 days) and group II included subjects with (&gt;3 days) readmission spanned 30days after surgery those are followed the old regimens of reduced oral feedings and full IV fluids from day zero and start clear oral fluids from day one till two weeks post operation (no balanced protocol between IV fluids and when to start clear and solid food time and regimens). Univariate and multivariate logistic regression were used to evaluate effect induced parameters on lengthened hospital admission and readmissions.

Results
The average period of hospitalization was 3 (2–4) days of hospital admission (HD), more days were recorded in 150/450 (33%) subjects: 90/300 (30%) LSG, and 60/150 (40%) LRYGB (P &lt; 0.005). SO, Reduced postoperative oral feeding, the old regimens, lengthened hospitalization, and increased readmission risk. Readmission incidence was 6% (27/450 readmissions): 16/300 (5%) LSG, and 11/150 (7%) LRYGB (P &gt; 0.05).

Conclusion
The old feeding protocols and reduced oral feeding is a risk factor for lengthened hospitalization and readmission. And the early feeding with the new feeding protocols decreases hospital stays postop and decrease re admissions.

Abstract

Introduction
Since the introduction of Single anastomosis Sleeve ileal Bipartition (SASI) many studies have focused on the nutritional malnutrition effect of SASI. Although there is still no consensus on whether SASI causes malnutrition, many studies have disagreed with such claims. In this study, we focused on re-evaluating the malnutritional effects of SASI using the same methodology in the short-term outcome.

Methods
147 cases of SASI were recruited retrospectively from 2018 to 2023 with a 2-year follow-up period. All cases had undergone periodical follow-ups for Cholesterol, LDL, HDL, TG, Serum iron, Ferritin, Calcium, Vitamin D3, and Vitamin B12.

Results
Postoperative Lipid profile significantly reduced (P ≤ 0.001). However, there was no significant reduction in serum iron (P = 0.387), Ferritin (P = 0.061), and serum calcium (P = 0.091). with postoperative supplementation, there was a significant reduction in, Vitamin D3 (P ≤ 0.001), and Vitamin B12 (P ≤ 0.001).

Conclusion
Although there is a rising concern for malnutrition with SASI, unification of the SASI technique, and the usage of the correct postoperative supplementation with regular follow-ups does avoid malnutrition.
IBC Oxford University Poster Abstract 10 - Conversion to laparotomy for laparoscopic sleeve gastrectomy post endoscopic sleeve gastroplasty
Authors: Al Haifi M , Hassan I 
Published: February 2025

Abstract

Introduction
Endoscopic Sleeve Gastroplasty (ESG)is an endoscopic minimally invasive weight loss procedure based on full thickness endoscopic suturing using Apollo’s Overstitch device. In the ESG procedure a series of sutures are placed through the gastric wall reducing the stomach volume by 80%creating a restrictive endoscopic sleeve.

Case Discussion
52 years old lady with a Body mass index of 39 kg/m2 with previous history of Endoscopic gastroplasty (EGP) done 2 years before with no significant response regarding weight loss. Had been counselled for Laparoscopic Sleeve Gastrectomy (LSG). Preoperative gastroscopy showed loose intragastric sutures and wide stomach. During LSG tense gastric bed adhesions were noticed (suspected sealed old leak) during adhesiolysis a major arterial bleeding at splenic bed noticed that required immediate conversion to laparotomy. Bleeding from splenic artery was controlled by primary repair with proline sutures and sleeve Gastrectomy was performed open. Patient had smooth recovery. Follow up CT was performed 2 days after procedure that revealed patent splenic artery and no gastric tube leakage. Patient was kept for two weeks on low molecular weight heparin to avoid mesenteric vascular occlusion.

Conclusion
EGP can be converted to LSG for non-responders, but extra care should be taken during surgery especially if a sealed leakage is suspected from history or during procedure.
IBC Oxford University Poster Abstract 12 - Naturally banded sleeve gastrectomy (sewefy wrap) versus non-banded sleeve gastrectomy, reporting of early results
Authors: Sewefy A M , Esmaeel T E , Kayed T H 
Published: February 2025

Abstract

Background
Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric procedure, but weight regain remains the main drawback. Banded Sleeve improves the long-term result of LSG on weight loss but, as a foreign body, it has some serious complications. We aimed to test the efficacy of using the round ligament of the liver as a natural band with LSG.

Methods
A prospective randomized controlled trial was conducted from October 2022 to December 2023 at Minia university hospital, included 80 patients. Patients were randomly assigned to 2 equal groups. Group 1: patients were operated by LSG plus banding using the round ligament of the liver. Group 2: patients were operated on by standard LSG without banding. All cases completed one year follow up.

Results
Of the patients, 55 (68.8%) were females, and 25 (31.2%) were male. The mean BMI was 47.6 kg/m2. The mean age was 36.3 years. The operative time was 37 minutes in Group 1 versus 33 minutes in Group 2 (P &lt; .001). The mean gastric volume at one year in Group 1 was 110 ml versus 147 ml in Group 2 (P &lt; .0001). The mean %EWL at one year in Group 1 was 85.8 versus 79.5 in Group 2 (P = 0.002). The mean score of food intolerance after one year was 20.8 in Group 1 versus 21.1 in Group 2 (P = .172).

Conclusion
Naturally banded SG leads to better weight loss than non-banded SG at one year after surgery with minimal sleeve pouch dilatation, but long term follow up is needed.
IBC Oxford University Poster Abstract 14 - The waist-to-hip ratio in bariatric surgery—does a higher ratio mean higher risk?

Abstract

Background
Obesity is rapidly emerging as a significant epidemic in developing countries. Although promising therapeutics are in development, bariatric surgery remains the most effective treatment. To better characterize this disease, waist and hip circumference measurements, and waist-to-hip ratio were developed. These measures provide valuable insights into body fat distribution and its associated health risks, enabling more accurate assessments and targeted interventions.

Methods
A retrospective review of 858 patients submitted to bariatric surgery between 1st January 2019 and 31st December 2023 and comprising waist-to-hip ratio data, was performed. The study’s primary objective was to analyze the correlation between a higher waist-to-hip ratio and perioperative and postoperative complications, as well as surgery duration and conversion rates. Other variables proven to be significantly related to a higher waist-to-hip ratio, namely patients’ comorbidities such as arterial hypertension, dyslipidemia, diabetes mellitus, and obstructive sleep apnea syndrome (OSA) were also included.

Results
There was no significant correlation between waist-to-hip ratio and post-operative complications (M = 0.95; SD = 0.10 versus M = 0.94; SD = 0.09; P = 0.07), neither surgery duration (r = 0.043, P = 0.223), nor conversion rates (due to sample size, n = 0). As a secondary outcome, there was a higher proportion of individuals with diabetes, dyslipidaemia, and OSA among those who had complications and, after adjustment, diabetes remained associated with higher complications (OR = 1.70, 95% c.i. [1.01, 2.87]).

Conclusions
Although there was no significant correlation between a higher waist-to-hip ratio and surgical complications, it was possible to establish a significant relationship between secondary variables, namely the presence of diabetes, and a greater risk of surgical complications. By understanding these relationships, healthcare providers can better identify at-risk patients and tailor surgical approaches to minimize complications and optimize outcomes aiming to enhance patient safety and surgical success.
IBC Oxford University Poster Abstract 16 - In the era of ‘sleeve revision’, what is the perfect algorithm? Suggested algorithm with review of the literature
Authors: Mohamed E 
Published: February 2025

Abstract

Background
Laparoscopic sleeve gastrectomy (LSG) is the mainstream treatment option for patients with morbid obesity due to restrictive and endocrine mechanisms, however it requires modifications for a subset of patients because of weight regain and tough complications, such as gastroesophageal reflux, strictures, gastric leak, and persistent metabolic syndrome. Revision surgeries have become more and more indispensable in bariatric surgery, accounting for 7.4% in 2016.

Methods
A systematic literature search was performed in PubMed, Embase and Cochrane library. Data were collected and analysed.

Results
Revisional bariatric surgeries after LSG include Roux-en-Y gastric bypass, repeated sleeve gastrectomy, biliopancreatic diversion, duodenal switch, duodenal-jejunal bypass, one-anastomosis gastric bypass (MGB), single anastomosis duodeno-ileal bypass (SADI) and transit bipartition. The overall revision rate was 10.4%, but for patients with ≥10-year follow-up, the rate was 22.6%. European studies had a higher revision rate (14.4%) than other studies. The most common reason for revision was failure in weight loss, and the most frequent revisional procedure was gastric bypass.

Conclusion
Reaching a clear algorithm for revisional bariatric surgery is still debated. However, we assume that it depends mainly on pre-revisional BMI and presence of GERD symptoms as follows: patients with BMI&gt; 40 kg/m2 should receive Standard R-Y gastric bypass, those with BMI &lt;40 kg/m2 with GERD should have R-Y gastric bypass with long biliopancreatic limb or MGB with RY configuration. Patients with BMI &lt;40 kg/m2 without GERD may benefit from MGB or SADI.

Study Design.
Retrospective Cohort Study

Objective.
To quantify the pathology of the spine in patients with scoliosis through one-dimensional feature analysis.

Summary of Background Data.
Biplanar radiograph (EOS) imaging is a low-dose technology offering high-resolution spinal curvature measurement, crucial for assessing scoliosis severity and guiding treatment decisions. Machine learning (ML) algorithms, utilizing one-dimensional image features, can enable automated Cobb angle classification, improving accuracy and efficiency in scoliosis evaluation while reducing the need for manual measurements, thus supporting clinical decision-making.

Methods.
This study used 816 annotated AP EOS spinal images with a spine segmentation mask and a 10-degree polynomial to represent curvature. Engineered features included the first and second derivatives, Fourier transform, and curve energy, normalized for robustness. XGBoost selected the top 32 features. The models classified scoliosis into multiple groups based on curvature degree, measured through Cobb angle. To address class imbalance, stratified sampling, undersampling, and oversampling techniques were employed, with 10-fold stratified K-fold cross-validation for generalization. An automatic grid search was used for hyperparameter optimization, with K-fold cross-validation (K=3).

Results.
The top-performing model was Random Forest, achieving an ROC AUC of 91.8%. An accuracy of 86.1%, precision of 86.0%, recall of 86.0%, and an F1 score of 85.1% were also achieved. Of the three techniques employed to address class imbalance, stratified sampling produced the best out-of-sample results. SHAP values were generated for the top 20 features, including spine curve length and linear regression error, with the most predictive features ranked at the top, enhancing model explainability.

Conclusions.
Feature engineering with classical ML methods offers an effective approach for classifying scoliosis severity based on Cobb angle ranges. The high interpretability of features in representing spinal pathology, along with the ease of use of classical ML techniques, makes this an attractive solution for developing automated tools to manage complex spinal measurements.

Study design.
Secondary analysis of prospective study.

Objective.
To assess the risk factors for postoperative non-satisfaction despite improvement in the Oswestry Disability Index (ODI) two years after elective lumbar surgery.

Background.
The ODI and postoperative satisfaction are important markers of postoperative success. While ODI improvement is expected to correlate with satisfaction, their exact relationship remains unclear. Additionally, some patients may achieve functional improvement yet report non-satisfaction postoperatively.

Methods.
A secondary analysis was performed on a prospective study of patients undergoing lumbar surgery for degenerative conditions. Patients with a 2-year ODI and satisfaction follow-up were included. Risk factors for non-satisfaction despite ODI improvement were investigated using t-tests, Wilcoxon-tests, and Fisher’s-exact-tests. Significant variables were analyzed with multivariable logistic regression, adjusting for covariates.

Results.
355 patients (65±10 y, 58% female) were included. Non-satisfied patients showed significantly higher scores in pre- (64[52-76], P<0.001) and postoperative (36[20-44], P<0.001) ODI and lower absolute (18[8-30], P<0.001) and percentage (30[17-52], P<0.001) improvement rates from pre- to postoperatively. Higher baseline (OR1.03, 95%CI 1.01-1.05, P<0.001) and postoperative (OR1.08, 95%CI 1.06-1.10, P<0.001) ODI scores, and lower absolute (OR0.94, 95%CI 0.92-0.96, P<0.001) and percentage (OR0.95, 95%CI 0.94-0.97, P<0.001) improvement rates, were significant risk factors for experiencing non-satisfaction, despite ODI improvement. Higher fat infiltration (FI) of the multifidus (MF) (OR1.03, 95%CI 1.00–1.06, P=0.042) or the erector spinae (ES) (OR1.06, 95%CI 1.03–1.09, P<0.001) were significantly correlated with postoperative non-satisfaction, after adjusting for covariates.

Conclusion.
Higher pre- and postoperative ODI scores and lower ODI improvement were linked to postoperative non-satisfaction. Higher FI in the MF or ES was also a significant risk factor for postoperative non-satisfaction, despite ODI improvement. The findings highlight that postoperative satisfaction is influenced by various factors affected by ODI-measured disability. Additionally, paraspinal muscle health greatly affects postoperative outcomes and should guide preoperative planning and postoperative care.

Published: February 2025

Objectives:
To determine the impact of short-acting beta-blocker therapy on outcomes in adult patients with septic shock.

Data Sources:
We searched MEDLINE, Embase, and unpublished sources from inception to April 19, 2024.

Study Selection:
We included randomized controlled trials (RCTs) that evaluated short-acting beta-blockers compared with usual care in patients with septic shock.

Data Extraction:
We collected data regarding study and patient characteristics, beta-blocker administration, and clinical, hemodynamic, and biomarker outcomes.

Data Synthesis:
Twelve RCTs proved eligible (n = 1170 patients). Short-acting beta-blockers may reduce 28-day mortality (relative risk [RR], 0.76; 95% CI, 0.62–0.93; low certainty) and probably reduce new-onset tachyarrhythmias (RR, 0.37; 95% CI, 0.18–0.78; moderate certainty) but may increase the duration of vasopressors (mean difference [MD], 1.04 d; 95% CI, 0.37–1.72; low certainty). Furthermore, there is an uncertain effect as to whether short-acting beta blockers impact 90-day mortality (RR, 0.98; 95% CI, 0.73–1.31), ICU length of stay (MD, –0.75 d; 95% CI, –3.43 to 1.93 d), hospital length of stay (MD, 1.03 d; 95% CI, –1.92 to 3.98 d), duration of mechanical ventilation (MD, –0.10 d; 95% CI, –1.25 to 1.05 d) (all very low certainty), bradycardia episodes (RR, 3.14; 95% CI, 0.91–14.01), and hypotension episodes (RR, 4.74; 95% CI, 1.62–14.01) (all very low certainty).

Conclusions:
In patients with septic shock, short-acting beta-blockers may improve survival and reduce new-onset tachyarrhythmias. However, these findings were based on low certainty evidence and given ongoing concerns regarding adverse effects and the increase duration of vasopressor use, we need larger and more rigorous RCTs to evaluate this intervention.

Abstract

Background
Lupus cystitis may cause significant lower urinary tract symptoms (LUTS). This study aimed to evaluate LUTS and identify potential risk factors in female patients with systemic lupus erythematosus (SLE).

Materials and methods
In this case-control study, 46 female patients with SLE were assessed for LUTS using the International Consultation on Incontinence Modular Questionnaire on Female Lower Urinary Tract Symptoms (ICIQ-FLUTS). The findings were compared with a control group of 20 women.

Results
The total incidence rates of LUTS in the SLE and control groups were 82.6% and 55%, respectively (p = 0.022). Statistically significant differences were observed between the 2 groups in symptom duration (p < 0.001), filling (p < 0.001), voiding (p = 0.001), incontinence (p < 0.001), and total LUTS scores (p < 0.001) as measured by ICIQ-FLUTS. Additional significant differences included renal echogenicity (p = 0.003), bladder wall thickness (p = 0.045), and the presence of pus cells in urine (p = 0.045). The possible risk factors for the occurrence of LUTS in patients with lupus cystitis included rapid weight loss (p = 0.025), easy fatigability (p = 0.006), fever (p = 0.046), psychosis (p = 0.033), and both renal (p = 0.025) and clinical (p = 0.047) SLE disease activity indices. The Spearman correlation between the total ICIQ-FLUTS score and the SLE Disease Activity Index was not significant (r = −0.203; p = 0.181). However, a statistically significant but weak correlation was observed between the ICIQ-FLUTS score and easy fatigability (r = 0.381; p = 0.013).

Conclusions
The ICIQ-FLUTS demonstrated acceptable content validity and consistency in evaluating LUTS in patients with lupus cystitis. Rapid weight loss, easy fatigability, fever, psychosis, and elevated renal and clinical SLE Disease Activity Index scores were significantly associated with the occurrence of LUTS in these patients.
