Study of penehyclidine for the prevention of postoperative nausea and vomiting following laparoscopic sleeve gastrectomy under general anesthesia: a randomized, prospective, double-blind trial.

To investigate the efficacy of penehyclidine (PHC) for preventing postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG) under general anesthesia. In this prospective study, 219 patients who were scheduled to undergo LSG were randomly assigned to three cohorts: the control cohort (received normal saline), the infusion cohort (administered 0.25mg of PHC intravenously followed by an additional 0.25mg through an intravenous analgesia pump for 48h after LSG), and the bolus cohort (received a single intravenous dose of 0.5mg of PHC). The study outcomes included the incidence of PONV within the first 48h postoperatively, the severity and intensity of PONV, side effects and postoperative recovery outcomes. Univariate and multivariate logistic analyses were performed to identify independent risk factors associated with PONV. Compared with the control cohort, both the infusion and bolus cohorts presented considerably lower incidences of PONV (61.64% vs. 12.33% vs. 38.36%, P < 0.05), as well as significantly decreased PONV severities (P < 0.05) and intensities (P < 0.05). There were no significant differences in side effects and postoperative recovery outcomes among the three cohorts, with the exception of dry mouthand the administration of rescue antiemetic therapy (P < 0.05). Additionally, the Apfel risk score and PHC intervention were identified as independent risk factors associated with PONV incidence following LSG (P < 0.05). PHC effectively prevented PONV occurrence and reduced its severity in LSG patients without decreasing postoperative recovery outcomes, particularly in the infusion cohort.

Surgical treatment strategies for gastroesophageal reflux after laparoscopic sleeve gastrectomy.

Bariatric surgery has emerged as an effective therapeutic approach for combating obesity. As the most commonly performed bariatric surgery, laparoscopic sleeve gastrectomy (LSG) has a long-term and effective outcome in weight reduction. However, studies have reported an increased incidence of gastroesophageal reflux disease (GERD) among patients after LSG. For those who fail to respond to conventional oral acid-suppressing medication, surgical intervention comes into consideration. The most commonly performed revisional surgery for sleeve gastrectomy is the Roux-en-Y gastric bypass, which can effectively alleviate the symptoms of reflux in patients and also continues to promote weight loss in patients who have not achieved satisfactory results or have experienced weight regain. In addition to this established procedure, innovative techniques such as laparoscopic magnetic sphincter augmentation (MSA) are being explored. MSA is less invasive, has good reflux treatment outcomes, and its safety and efficacy are supported by the literature, making it a promising tool for the future treatment of gastroesophageal reflux. This article also explores the role of endoscopic interventions for GERD treatment of post-sleeve gastrectomy patients. Although these methods have shown some therapeutic effect, their efficacy still requires further study due to a lack of support from more clinical data. For patients with preoperative hiatal hernia or gastroesophageal reflux symptoms, some experts now consider performing LSG combined with hiatal hernia repair or fundoplication to alleviate or prevent postoperative reflux symptoms. Both of these surgical approaches have demonstrated favorable outcomes; however, the addition of fundoplication requires further investigation regarding its long-term effects and potential postoperative complications. This article gathers and examines the current laparoscopic and endoscopic treatments for refractory gastroesophageal reflux following LSG, as well as the concurrent treatment of LSG in patients with preoperative gastroesophageal reflux or hiatal hernia.

The effect of preadmission education given to bariatric surgery patients on postoperative recovery: A randomized controlled study.

To investigate the effect of preadmission education given to laparoscopic sleeve gastrectomy patients on preoperative and postoperative anxiety, postoperative pain, and patient vital signs. The study was designed as randomized, controlled, experimental, and single-blind. This study was conducted with 68 patients who met the inclusion criteria and underwent laparoscopic sleeve gastrectomy in the general surgery clinic of a university hospital between December 2022 and October 2023. Data were collected using the 'Perioperative Form,' 'Visual Analog Scale,' and 'State Anxiety Scale I-II.' Intervention group patients were informed and educated about the surgical process in the outpatient clinic. The anxiety levels of all patients were determined with the State Anxiety Scale the day before surgery. In the postoperative period, vital signs (once), anxiety (on the first day after surgery), and pain levels (eight times during 48 h) were measured. In the analysis between the groups, the difference between the duration of postoperative hospital stay (p = 0.007), pain (p = 0.000 for all measured), and anxiety levels (p = 0.000) was statistically significant. There were also significant differences in the diastolic blood pressure (p = 0.007), body temperature (p = 0.000), and saturation values (p = 0.000). Patients' readiness level for surgery was the most influential factor in postoperative pain levels (p = 0.000). The education given to the patients before hospitalization decreased preoperative and postoperative anxiety levels, postoperative hospital stay and pain levels, and positively affected diastolic blood pressure, body temperature and saturation levels. One-to-one education given to patients in the outpatient clinic also contributes positively to their readiness for surgery. This study provides valuable evidence to the wider global clinical community by demonstrating the important benefits of preadmission education for patients undergoing bariatric surgery. Implementation of similar educational interventions in diverse healthcare settings worldwide may lead to increased postoperative recovery and improved overall patient well-being after bariatric surgery.

The Effects of Laparoscopic Sleeve Gastrectomy on Body Mass Index (BMI) and Glycated Hemoglobin (HbA1c) Levels.

Background and significance Bariatric surgery is an effective surgical intervention for weight loss and metabolic improvement. Articles tackling obesity and bariatric surgery with its preoperative preferences and postoperative findings are needed. From that stance, we aim to accurately document the impact of bariatric surgery, particularly laparoscopic sleeve gastrectomy (LSG), on body mass index (BMI) and glycated hemoglobin (HbA1c) levels. Patients and methods We present a retrospective cohort study conducted on 111 LSG patients from a total of 1633 patients who underwent bariatric surgery from January 23, 2018, to December 31, 2019, at King Saud University Medical City in Riyadh, Saudi Arabia. Patients were divided into three groups: nondiabetics, prediabetics, and diabetics. For each group, demographic characteristics as well as preoperative and postoperative BMI and HbA1c values were collected. Results The mean patient age was 41.35±11.8 years, with 56.8% being female. Our analysis showed that BMI values for all three groups had a significant and nearly similar overall decrease in value postoperatively (mean difference: 14.43, p<0.001). HbA1c levels also significantly improved, with the largest reduction seen in the diabetic group (from 8.7±1.5 to 6.6±1.4, p<0.001), followed by the prediabetic group (from 5.9±0.2 to 5.4±0.3, p<0.001) and the nondiabetic group (from 5.4±0.1 to 5.2±0.3, p=0.003). Conclusion LSG leads to significant improvements in BMI and HbA1c levels. Postoperatively, diabetic patients showed the greatest reduction in HbA1c percentage, supporting LSG's role in enhancing metabolic health.

Comparable improvement and resolution of obesity-related comorbidities in endoscopic sleeve gastroplasty vs laparoscopic sleeve gastrectomy: single-center study.

Despite excellent surgical outcomes, a minority of qualified patients undergo weight loss surgery. Endoscopic Sleeve Gastroplasty (ESG), an incisionless procedure, has proven to be effective in achieving weight loss and comorbidity improvement. We aim to compare outcomes of ESG to those of Laparoscopic Sleeve Gastrectomy (LSG). A retrospective review of a prospective database of patients who underwent ESG and LSG at NorthShore University HealthSystem from 2016 to 2023 was completed. Demographic and outcome data were analyzed. Pre- and post-surgical data were compared using chi-square and two-sample t tests. Improvement or resolution of obesity-related comorbidities were also assessed. A total of 212 LSG and 68 ESG patients were reviewed. ESG patients were older (47 ± 10 vs. 43 ± 12, p = 0.006) and less obese (BMI 37.0 ± 5.5 vs. 45.8 ± 0.4, p < 0.001) than LSG patients. Median length of stay after ESG was 0days and after LSG 1day (p < 0.001). Severe adverse events were seen less frequent after ESG (1.47%, vs 3.77%). LSG achieved more significant %TBWL at 6 months (25.2 ± 8.9 vs 14.9 ± 7.4), 1 year (27.5 ± 10.8 vs 14.1 ± 9.8), and 2 years (25.7 ± 10.8 vs 10.5 ± 8.8, all p < 0.001) after surgery when compared to ESG. LSG achieved significantly greater %EWL compared to ESG at 6 months (57.0 ± 20.7 vs 50.4 ± 29.2, p = 0.137), 1 year (61.4 ± 24.6 vs 46.5 ± 34.0, p = 0.026), and 2 years postoperatively (59.7 ± 25.5 vs 32.6 ± 28.2, p = 0.001). There were no statistically significant differences in rates of improvement or resolution of diabetes, obstructive sleep apnea, hyperlipidemia, or hypertension. ESG is an effective procedure for weight loss and comorbidity resolution. Obesity-related comorbidities are comparably improved and resolved following ESG vs LSG. Although the weight loss in LSG is significantly higher, patients can expect a shorter hospital length of stay and a lower rate of complications after ESG. ESG continues to show promise for long-term weight loss and improvement in health.

Does the Repair of an Accidentally Discovered Hiatal Hernia and Gastropexy Affect the Incidence of De Novo Postoperative GERD Symptoms After Laparoscopic Sleeve Gastrectomy?

The relationship between laparoscopic sleeve gastrectomy (LSG) and gastroesophageal reflux disease (GERD) is intricate. Hiatal hernia repair or gastropexy can have an impact on postoperative GERD. To assess the effect of the repair of an accidentally discovered HH and/or gastropexy on the development of de novo postoperative GERD symptoms after LSG. This retrospective study included all obese patients who underwent LSG at our hospital from January 2018 to June 2022. The data retrieved from patients' files comprised demographic and clinical data, including BMI, GERD symptoms, and comorbidities. Hiatal hernias, surgical technique, gastropexy, duration, and intraoperative complications were recorded. Postoperative data included early and late postoperative complications, weight loss, de novo GERD, and medication use. The study included 253 patients, 89 males (35.2%) and 164 females (64.8%), with a mean age of 33.3±10.04 years. De novo GERD was detected in 94 individuals (37.15%). HH was accidentally found and repaired in 29 patients (11.5%). Only 10.3% of LSG and HH repair patients had de novo GERD symptoms, compared to 40.6% of non-HH patients. 149 patients (58.9%) had gastropexy with LSG. Postoperative de novo GERD symptoms were comparable for LSG with gastropexy (40.5%) and LSG alone (40.9%). After one year, concurrent hiatal hernia repair and LSG seem to be safe and beneficial in lowering postoperative de novo GERD symptoms. The inclusion of gastropexy with LSG had no significant impact on postoperative de novo GERD. Both HH repair and gastropexy lengthened the operation but did not increase its complications.

Comparing the Efficacy of Robotic Versus Laparoscopic Sleeve Gastrectomy: A Systematic Review and Meta-Analysis.

Laparoscopic sleeve gastrectomy (LSG) has emerged as the predominant metabolic bariatric surgery. With a growing number of studies evaluating the feasibility of robotic sleeve gastrectomy (RSG), it becomes imperative to ascertain whether the outcomes of both techniques are comparable. This study endeavors to synthesize existing evidence and juxtapose the surgical outcomes of LSG and RSG. We collected articles comparing LSG and RSG published between 2011 and 2024. The compiled data included author names, study duration, sample size, average age, gender distribution, geographical location, preoperative body mass index (BMI), bougie diameter, duration of hospitalization, surgical duration, readmission rates, conversion rates, costs, postoperative percentage of excess weight loss (%EWL), postoperative BMI, mortality rates, and complications. We incorporated 21 articles. Both the RSG and LSG cohorts exhibited comparable rates of readmission, conversion, mortality, and incidence of complications (p > 0.05). Moreover, the efficacy of weight loss was similar between RSG and LSG. Nonetheless, RSG was linked to longer operative duration (WMD, -27.50 minutes; 95% confidence interval [CI], -28.82 to -26.18; p < 0.0001), prolonged hospitalization (WMD, -0.15 days; 95% CI, -0.25 to -0.04; p = 0.006), and elevated expenses (WMD, -5830.9 dollars; 95% CI, -8075.98 to -3585.81; p < 0.0001). While both RSG and LSG demonstrated positive postoperative clinical outcomes, RSG patients experienced extended hospital stays, longer operative times, and increased hospitalization costs compared to LSG patients. Using the robotic platform for sleeve gastrectomy (SG) in patients with obesity did not appear to offer any clear benefits.

Pain Assessment and Analgesic Requirements after Sleeve Gastrectomy: A Comparison Study of Robotic versus Laparoscopic Approaches.

Background: Sleeve gastrectomy is the most common bariatric procedure worldwide, yet postoperative pain management remains a concern. This study aimed to compare pain medication usage and pain scores between laparoscopic sleeve gastrectomy (LSG) and robotic sleeve gastrectomy (RSG) patients, addressing the potential benefits of RSG in postoperative pain control. Methods: A retrospective review of our institutional bariatric surgery registry included 484 patients (435 LSG, 49 RSG) who underwent surgery between September 2015 and November 2020. Pain management medications, including opioid use converted to morphine milligram equivalents (MMEs), and Numerical Rating Scale (NRS) scores were analyzed postoperatively using mixed-effects models. Results: RSG patients reported lower pain scores in the initial 24 h post-surgery and received significantly lower doses of morphine equivalents compared to LSG patients (median 7.5 mg vs. 12.5 mg, p < 0.001). RSG procedures had longer operative times (122.5 ± 27.1 vs. 89.9 ± 30.5 min, p < 0.001) but a shorter average length of stay (2.24 ± 0.60 vs. 2.65 ± 1.49 days) compared to LSG. Conclusions: These findings suggest that RSG may lead to reduced immediate postoperative pain and lower opioid requirements compared to the laparoscopic approach, despite longer operative times. Further randomized controlled trials are needed to confirm these observations and evaluate long-term outcomes.

A superior approach? The role of robotic sleeve gastrectomy in patients with super super obesity using the 2019-2022 MBSAQIP database.

Laparoscopic sleeve gastrectomy (LSG) in patients with BMI ≥ 60 presents technical challenges, that might be overcome by robotic surgery, but its effectiveness has not been rigorously evaluated. We compared the 30-day outcomes of LSG and robotic sleeve gastrectomy (RSG) in patients with BMI < 60 versus ≥ 60 and between LSG and RSG in patients with BMI ≥ 60. Patients aged 18-65 years who underwent sleeve gastrectomy were included using the 2019-2022 MBSAQIP database. We performed a Propensity Score Matching analysis, with 21 preoperative characteristics. We compared 30-day postoperative outcomes for patients with BMI < 60 versus ≥ 60 using either a laparoscopic (Analysis 1) or robotic approach (Analysis 2) and compared LSG versus RSG in patients with BMI ≥ 60 (Analysis 3). 297,250 patients underwent LSG and 81,008 RSG. Propensity-matched¸ outcomes in analysis 1 (13,503 matched cases), showed that patients with BMI ≥ 60 had higher rates of mortality (0.1% vs. 0.0%, p=0.014), staple line leak (0.3% vs. 0.2%, p=0.035), postoperative bleeding (0.2% vs 0.1%, p=0.028), readmissions (3.5% vs. 2.4%, p<0.001), and interventions (0.7% vs. 0.5%, p=0.028) when compared to patients with BMI < 60. In analysis 2 (4350 matched cases), patients with BMI ≥ 60 demonstrated longer operative times, length of stay, and higher rates of unplanned ICU when compared to patients with BMI < 60. In analysis 3 (4370 matched cases), patients who underwent RSG had fewer readmissions (2.9% vs. 3.7%, p=0.037), staple line leaks (0.1% vs. 0.3%, p=0.029), and postoperative bleeding (0.1% vs. 0.3%, p=0.045), compared to LSG. Conversely, a longer operative time (92.74 ± 38.65 vs. 71.69 ± 37.45 min, p<0.001) was reported. LSG patients with BMI ≥ 60 have higher rates of complications compared to patients with a BMI < 60. Moreover, some outcomes may be improved with the robotic approach in patients with BMI ≥ 60. These results underscore the importance of considering a robotic approach in this super super obese population.

SAFETY AND FEASIBILITY OF THE THREE PORT TECHNIQUE FOR CONCOMITANT CHOLECYSTECTOMY DURING SLEEVE GASTRECTOMY: A COMPREHENSIVE ANALYSIS AND CLINICAL IMPLICATIONS

Introduction:Obesity, a prevalent global health issue, has led to an increased demand for bariatric surgeries, with laparoscopic sleeve gastrectomy (LSG) being a preferred option due to its efficacy and minimal invasiveness. Concomitant cholecystectomy (CC) during LSG has gained traction among patients with obesity and gallstones. While various techniques have been explored, concerns persist regarding safety and efficacy. Our study aims to evaluate the feasibility and outcomes of a three-port laparoscopic technique for this combined procedure. Methodology:Ahigh-volume bariatric center in Saudi Arabia conducted a retrospective cohort study involving patients who underwent three-port sleeve gastrectomy (3PSG) with CC between January 2022 and January 2024. We collected and analyzed data on demographics, preoperative evaluation, intraoperative details, and postoperative outcomes using descriptive statistics. Results:Out of 360 LSG patients, 76 underwent CC with the three-port technique. The mean age was 42.18 years, with a female predominance (71.0%) and a mean BMI of 44.67 kg/m2. Intraoperatively, the mean operative time was 109.8 minutes, with minimal blood loss and no complications or conversions to open surgery. The average hospital stay was 2.1 days. Postoperatively, the complication rate was 4%, primarily consisting of early bleeding, port-site infection, and atelectasis, all of which were managed conservatively. No severe complications, mortalities, or thrombotic events occurred during the 3-month follow-up. Conclusion:Thethree-port laparoscopic technique for concomitant cholecystectomy during sleeve gastrectomy appears safe and feasible, offering favorable outcomes in terms of operative time, blood loss, and postoperative complications. This approach presents a promising option for minimizing surgical trauma and enhancing recovery in obese patients who require both procedures.

Management of staple line leaks after laparoscopic sleeve gastrectomy: Single-center experience

Objective: In obesity surgery, laparoscopic sleeve gastrectomy (LSG) is a frequently applied method. However, there are certain complications. Leakage is one of the most serious complications after surgery, causing postoperative morbidity and sometimes mortality. There is no consensus about management of leaks after LSG. In our study, we aimed to present our experience on the management of LSG leaks. Patients and Methods: Patients who underwent LSG between 2010-2017 in a tertiary university hospital were analyzed retrospectively. Demographic characteristics, endoscopic and surgical interventions, morbidity, and mortality rates of patients diagnosed with LSG leak were analyzed from prospectively recorded data. Results: Leak was observed in 11 (2.15%) of a total of 510 LSG patients. Six (54%) patients were diagnosed as acute and 5 were early leaks. Stent was applied to most of the patients (72%) with or without surgical exploration. The average length of stay in hospital was 21 days. Mortality was observed in 2 patients. Conclusions: Consequently, leakage after LSG is a complication that requires multimodal therapy. Surgical treatment combined with endoscopic intervention may increase success.

Laparoscopic Sleeve Gastrectomy: Suture or not Suture Staple Line

Background The severity of postoperative complications is the main disadvantage of laparoscopic sleeve gastrectomy (LSG). Staple line reinforcement (SLR) is strongly advocated. Recently, oversewing has been proposed as a cost-effective and helpful method for reinforcing the staple line. Aim of the study: To evaluate the benefit of staple lines over sewing in decreasing postoperative complications and their severity. Patients and methods: One hundred laparoscopic surgery group (LSG) patients were randomly assigned to either group (A) without staple line over sewing or (B) with staple line over sewing from January 2022 to January 2023 in a prospective study conducted at three hospitals (Alhussein Medical City, Alkafeel Private Hospital, and Zain Alabdin Private Hospital). We want to learn if laparoscopic sleeve gastrectomy patients benefited more from a staple line than a sewn one. Results: The most frequently reported complication was bleeding, which was reported in two patients in group A and one patient in group B, respectively; vomiting was reported more frequently in group B. The cross-tabulation between complications and comorbidities revealed no significant association between them. The hospital stay was the same in both groups except for patients with non-surgical complications, which need more hospital stay time. In regard to the severity of complications, we found that complicated cases in group A needed more hospital stays and more interventions to control the problem in comparison to those in group B. Conclusion: Laparoscopic sleeve gastrectomy with staple line over sewing is a technique that may decrease early complications and the severity of complications. There was no significant difference between the two groups (with and without staple line over sewing) in regard to the relation between complications on one side and the comorbidity on the other.

Laparoscopic Sleeve Gastrectomy Smart Trocar Site Modification in Patients with Extreme Obesity.

Laparoscopic sleeve gastrectomy (LSG) is one of the most common bariatric surgeries performed worldwide. Although it has established itself as a satisfactory procedure on its own, it can also function as the first part of a two-stage treatment strategy. This is especially true in situations of extreme obesity (obesity grade IV or higher). One rationale for choosing a two-stage treatment is the technical difficulty of doing other types of bariatric procedures involving anastomoses due to body physique and level of visceral adiposity. LSG in patients with such a high body mass index (BMI) is comparatively simpler technically, but it does also have a degree of complexity for similar reasons. Here, we present an innovative port configuration for LSG that can significantly reduce ergonomic challenges and enhance the safety of the procedure in patients with extreme obesity. This new trocar site arrangement is generally suitable for individuals with grade IV obesity or above. It is especially effective for people with obesity at or above grade V. Only standard laparoscopic instruments are used. This design preserves the ideal manipulation and elevation angles at 60° and allows surgeons to use standard laparoscopic instruments with lowered shoulders, reducing muscular strain and fatigue. Additionally, it improves patient safety. In patients with extreme obesity, this proposed port configuration for LSG can significantly reduce ergonomic difficulties and increase surgical safety.

Short-Term Changes in Weight, Body Composition, and Metabolic Biomarkers After Laparoscopic Sleeve Gastrectomy in Patients with Obesity: A Comparative Prospective Study.

To investigate the changes in weight, body composition, and metabolic biomarkers in patients with obesity after laparoscopic sleeve gastrectomy (LSG) and compare those changes between patients with and without metabolic syndrome (MS). This retrospective longitudinal study included 76 patients who underwent LSG, among whom 32 had complete 1-year postoperative body composition and metabolic biomarkers. Body composition was measured by quantitative CT. Weight changes were compared between the MS and non-MS groups at 1-, 3-, 6-, and 12-month post-LSG in all patients; changes in body compositions and metabolic biomarkers from one day pre-LSG to 12-month post-LSG were also compared in those 32 patients. MS occurred in 46% (35/76) of all patients and 44% (14/32) of patients with complete follow-up data. Excess weight loss was lower in the MS group than that in the non-MS group at 1-, 3-, 6-, and 12-month post-LSG; the 12-month difference was significant (MS vs. non-MS: 0.91 ± 0.22 vs. 1.07 ± 0.42, P = 0.04). The greatest rate of visceral fat area (VFA) change occurred 12-month post-LSG in both the non-MS [0.62(0.55,0.7)] and MS [0.6(0.51,0.63)] groups. The most significant reduction in ectopic fat occurred in liver fat (LF) [non-MS, 0.45(0.22,0.58); MS, 0.39(0.23,0.58)]. LGS significantly improves weight, body composition, and metabolic biomarkers in populations with obesity, regardless of whether they have MS. Among the body composition, VFA and LF were the most significantly improved body composition measurements.

Prevention of the stapler line leak after laparoscopic sleeve gastrectomy in patients with morbid obesity

Obesity has become a global pandemic, leading to increased morbidity and mortality among patients, both young and old. Bariatric surgery is the most effective method for treating pathological obesity. Laparoscopic sleeve gastrectomy has become the most popular bariatric procedure worldwide. However, staple line leak is the most dreaded postoperative complication following laparoscopic sleeve gastrectomy. In order to reduce the incidence of this complication, most surgeons prefer to reinforce the staple line. However, there is no compelling evidence to suggest that peritonealization of the staple line or the use of coated stapler cartridges during laparoscopic sleeve gastrectomy reduces the risk of leakage. Therefore, we conducted a retrospective analysis to assess the impact of coated stapler cartridges on preventing staple line leaks. The aim of the study. To evaluate the effect of using stapler with coating on preventing staple line leaks during laparoscopic sleeve gastrectomy in patients with morbid obesity. Materials and methods. This was a retrospective analysis of 45 patients who underwent laparoscopic sleeve gastrectomy using endostapler from Medtronic (Endo GIA™) without additional reinforcement (Group I) and 46 patients who underwent a similar procedure using endostapler from Medtronic (Endo GIA™) stapler with coating (Group II). Both patient groups were homogeneous in terms of demographic characteristics. We compared the duration of surgery, intraoperative blood loss, length of hospital stay, and the incidence of staple line leak. Results. The incidence of staple line leak was statistically significantly higher in Group I compared to Group II (5/40 vs. 0/46; χ2 = 5.4, p = 0.021). This resulted in a statistically significant increase in blood loss (U = 706; p = 0.006), prolonged total operation time (U = 310; p = 0.001), and extended postoperative hospital stay (U = 245; p = 0.001) in Group I. The median time to healing of the leak was 32 [20; 59] days. No patient died. Conclusions. Using the endostapler with purple cartridges with coating from Medtronic during laparoscopic sleeve gastrectomy significantly reduced postoperative leak rate and significantly decreased postoperative hospital stay.

Impact on carotid intima-media thickness after laparoscopic sleeve gastrectomy in patients with morbid obesity.

We aimed to investigate the impact of laparoscopic sleeve gastrectomy (LSG) on carotid intima-media thickness (CIMT) & left ventricular dysfunction (LVD) which are the independent predictors of subclinical atherosclerosis. To assess the change in CIMT & echocardiographic parameters of left ventricular function & correlate with %EWL 6months and 12months after LSG, the mean CIMT of bilateral common carotid arteries were measured at 3 different places & 7 parameters were assessed for left ventricular dysfunction after 6 and 12months of LSG & correlated with the %EWL. A total of 30 patients (27(90%) women & 3(10%) men) with the mean age of 38 ± 7.84 were prospectively enrolled. BMI was significantly reduced from 42.66 ± 3.79 to 37.93 ± 3.60kg/m2 at six months to 36 ± 3.34 at 12months after LSG. CIMT values were significantly decreased at 6months after surgery from 0.50 ± 0.11mm to 0.46 ± 0.09mm (p < 0.01) to 0.39 ± 0.07 (p < 0.05) at 12months. However, no significant change was observed in the right mean CCA values at 6months after surgery 0.50 ± 0.11mm vs 0.47 ± 0.09mm (p = 0.07) as compared to decrease at 12months after surgery to 0.40 ± 0.08 (p < 0.05). Left mean CCA values at 6months changed from 0.50 ± 0.11 to 0.45 ± 0.09 (p < 0.01) and at 12months after surgery to 0.39 ± 007(p < 0.05). On 2D ECHO, ejection fraction increased at 6months from 60.80 ± 5.89 to 61.93 ± 4.47 (p < 0.5) to after 12months at 64.30 ± 4.20 (p < 0.05). Wave deceleration time changed at 6months from 170 ± 36.80 to 150 ± 28.82 (p < 0.05) to 12months 139.07 ± 17.98 (p < 0.05). Peak early diastolic mitral annular velocity (e) changed at 6months from 8.12 ± 1.66 to 7.02 ± 1.76 (p < 0.05) to 12months 6.33 ± 0.76 (p < 0.05). Inter-ventricular septum thickness (IVSD) changed at 6months from 0.99 ± 0.14 to 0.91 ± 0.14 (p < 0.05) to 12months 0.82 ± 0.09 (p < 0.05). Intraventricular relaxation time (IVRT) at 6months changed from 94.33 ± 21.71 to 84.36 ± 14.85 (p < 0.03) to 12months after surgery 77.40 ± 10.19 (p < 0.05). Left atrial volume index (LAVI) at 6months decreased from 38.08 ± 11.23 to 30.93 ± 7.16 (p < 0.01) to 12months after surgery 25.43 ± 3.65 (p < 0.05). Left ventricular diastolic dysfunction [LVIDD] at 6months changed from 4.32 ± 0.52 to 4.11 ± 0.52 (p < 0.02) to 3.94 ± 0.26 (p < 0.05) to 3.94 ± 0.26 (p < 0.05) at 12months after surgery. PwD at 6 and 12months changed from 1.00 ± 0.19 to 0.87 ± 0.10 (p < 0.01) to 0.82 ± 0.08 (p < 0.05) respectively. LV mass changed in 6months from 148.37 ± 33.09 to 117 ± 29.90 (p < 0.001) to 12months at 110.64 ± 20.79 (p < 0.05) and left ventricular mass index [LVMI] changed in 6months from 70 ± 16.89 to 59.626 ± 15.35 (p < 0.001) reaching a value of 57.53 ± 11.18 (p < 0.05) at 12months. The mean 10-year risk of death due to CVD calculated was significantly reduced from 5.45 ± 6.6 to 2.8 ± 1.7% at 6months (p < 0.05). This significant decrease in CVD risk has a positive correlation with the decrease in CIMT over 6months showing a correlation coefficient of 0.018 with statistically significant analysis (p value < 0.05). We observed a significant reduction in CIMT & improvement in 2D ECHO parameters at 6 after LSG although no statistically significant change was observed in mean right CIMT & EF at 6months.

Ramadan fasting following laparoscopic sleeve gastrectomy: a prospective online survey cohort study in Egypt.

This study aims to explore the feasibility and implications of Ramadan fasting for patients who have undergone laparoscopic sleeve gastrectomy (LSG), assessing impacts on hydration, nutrient intake, weight management, and gastrointestinal symptoms. A prospective online survey was conducted among 218 LSG patients and 83 control individuals with obesity who had not undergone surgery. Participants were surveyed before and after Ramadan, providing data on fasting practices, hunger and satiety levels, fluid and nutrient intake, and the occurrence of gastrointestinal symptoms. Statistical analysis was used to compare outcomes between fasting and non-fasting periods and between LSG patients and control participants. A total of 70.2% of LSG patients completed the entire month of Ramadan fasting, with a significant correlation found between the duration post-surgery and the ability to fast. Fasting LSG patients reported decreased hunger, increased satiety, and significant reductions in fluid and nutrient intake during Ramadan. Weight loss was reported in 90.8% of fasting patients, with an average total weight loss of 7.2%. Gastrointestinal symptoms were mild and manageable. The majority of LSG patients can successfully fast during Ramadan with appropriate precautions, including adequate fluid and protein intake. The study highlights the need for patient education and tailored nutritional guidance to ensure safe and effective fasting post-LSG. In order to fast for the entire month, patients may be advised to consider postponing surgery for a few months after Ramadan, avoid overeating during non-fasting hours, and ensure sufficient fluid consumption and protein intake during fasting.

LSG vs OAGB: 7-Year Follow-up Data of a Randomised Control Trial and Comparative Outcome Based on BAROS Score.

This study aims to evaluate and compare long-term results of laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) based on bariatric analysis reporting and outcome system (BAROS) score. Patients operated for morbid obesity between 2013 and 2015 were randomised to LSG and OAGB groups. Based on inclusion and exclusion criteria, 201 patients (100 LSG and 101 OAGB) were analysed for changes in total body weight (TBW), body mass index (BMI), percent excess weight loss (%EWL), percent total weight loss (%TWL), QoL (quality of life) scores, comorbidity resolution and outcome based on BAROS at 7years. Sixty-six LSG and 64 OAGB patients were followed up at 7years. Mean pre-operative TBW and BMI were 119 ± 28.2 and 44.87 ± 7.71 for LSG group and 113.25 ± 23.74 and 44.71 ± 8.75 for OAGB group respectively. At 7years after surgery, there was significant drop in mean TBW and BMI in both groups. Mean %EWL for LSG and OAGB patients was 50.78 ± 28.48 and 59.99 ± 23.32 and mean %TWL for LSG and OAGB patients was 23.22 ± 12.66 and 27.71 ± 12.27 respectively. Mean QoL scores at 7years were significantly higher than the pre-operative scores and most of the patients in both groups had remission or improvement in their comorbidities. 68.76% OAGB patients had very good or excellent outcome on BAROS score while only 36.37% LSG patients had similar outcome. LSG and OAGB are successful bariatric procedures over the long term. OAGB outperforms LSG and has significantly higher %EWL and %TWL over the long term.

Rationale and Trial Protocol for a Double-Blinded Randomized Controlled Trial to assess the Impact of a Concomitant Crural Repair during Laparoscopic Sleeve Gastrectomy in Patients with a Lax Gastroesophageal Junction without Frank Hiatal Hernia (REPAIR trial protocol).

Laparoscopic sleeve gastrectomy (LSG) is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The role of crural repair during LSG is still controversial. The preoperative laxity of the gastroesophageal junction (GEJ), graded by the Hill's classification, is more predictive for postoperative GERD and EE after LSG than the presence of a hiatal hernia seen on endoscopy. Thus, the authors hypothesize that a concomitant crural repair in a specific subgroup of patients with a lax GEJ (Hill's III) may reduce the incidence of postoperative GERD and EE. A double-blinded, randomized controlled trial of patients with Hill's III GEJ undergoing LSG will be randomized to a concomitant crural repair (experimental) versus LSG alone (control). Primary outcome measures will be presence of EE at 1-year. Secondary outcome measures will include proton pump inhibitor use, postoperative complications, operative time, blood loss, quality of life, GERD and gastrointestinal symptoms. Conflicting crural repair results may be explained by differences in preoperative GEJ laxity. Patients with a frank hiatal hernia and patulous GEJ (Hill's IV) have a very high, while patients with an apposed GEJ (Hill's I, Hill's II) have a low incidence of postoperative GERD and EE respectively. Thus, the authors hypothesize that patients with a lax GEJ without frank hiatal hernia (Hill's III), might benefit from a crural repair. This study results can potentially highlight the clinical importance of preoperative endoscopic evaluation of the GEJ in all patients planned for LSG, to determine which subgroup patients may benefit from a crural repair.

A Simple Way to Estimate a Difficult Sleeve Gastrectomy Prior to Operating

BackgroundToday, bariatric procedures are common. These surgeries’ difficulties are classified as patient- or surgical team–related and are estimated by body mass index (BMI). More efficient methods are needed to help surgeons. This study evaluated the effect of measuring patients’ subcutaneous fat tissue thickness (SFT) and umbilicus-xiphoid (DXU) to anticipate surgical difficulties.Material and MethodsThis was a prospective retrospective data analysis study. Laparoscopic sleeve gastrectomy patients seen between May and October 2022 were included in the analysis and divided into three groups, according to a surgeon’s assessment. All patients’ SFT, DXU, rectus muscle thickness, total fat tissue amount (TFT), and operational time were recorded prospectively and analyzed.ResultsIn all, 151 patients were included in the study; of these, 124 (82.1%) were women and 27 (17.9%) were men. Their mean BMI value was 41.1 ± 6.2. Based on expert’s opinion, we classified three groups: easy (n = 123, 81.5%), intermediate (n = 22, 14.6%), or difficult (n = 6, 4%). When the easy group was compared to the intermediate/difficult groups, we found that intermediate/difficult groups’ SFT values were statistically significantly higher than the easy group (p = 0.000). Also, the intermediate/difficult group’s TFT value was statistically significantly higher than the easy group (p = 0.000). We found no statistically significant differences between groups’ DXU and rectus muscle thickness.ConclusionThis is the first study to anticipate sleeve gastrectomy difficulty using SFT and TFT. This is an easy technique to apply and no additional costs. Anticipating difficulties based on these criteria can ensure necessary preparations are made and help avoid complications.Graphical
