Treatment of giant hiatal hernia by laparoscopic Roux-en-Y gastric bypass
Introduction Obesity is a risk factor for hiatal hernia. In addition, much higher recurrence rates are reported after standard surgical treatment of hiatal hernia in morbidly obese patients. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective surgical treatment for morbid obesity and is known to effectively control symptoms of gastroesophageal reflux (GERD). Case presentation Two patients suffering from giant hiatal hernias where a combined LRYGB and hiatal hernia repair (HHR) with mesh was performed are presented in this paper. There were no postoperative complications and at 1 year follow-up, there was no sign of recurrence of the hernia. Discussion The gold standard for all symptomatic reflux patients is still surgical correction of the paraesophageal hernia, including complete reduction of the hernia sac, resection of the sac, hiatal closure and fundoplication. However, HHR outcome is adversely affected by higher BMI levels, leading to increased HH recurrence rates in the obese. Conclusion Concomitant giant hiatal hernia repair with LRYGB appears to be safe and feasible. Moreover, LRYGB plus HHR appears to be a good alternative for HH patients suffering from morbid obesity as well than antireflux surgery alone because of the additional benefit of significant weight loss and improvement of obesity related co-morbidity
Reducing complication rates and hospital readmissions while revising the enhanced recovery after bariatric surgery (ERABS) protocol
Background: To optimize the postoperative phase following bariatric surgery, the enhanced recovery after bariatric surgery pathway (ERABS) has been developed. The aim of ERABS is to create a care path that is as safe, efficient and patient-friendly as possible. Continuous evaluation and optimization of ERABS are important to ensure a safe treatment path and may result in better outcomes. The objective of this study was to compare the clinical outcomes of patients undergoing bariatric surgery over 2014–2017, during which the ERABS protocol was continuously evaluated and optimized. Methods: This is a retrospective cohort study. Data were collected from patients undergoing a primary Roux-en-Y gastric bypass or sleeve gastrectomy between January 2014 and December 2017. Outcomes were early complications, unplanned hospital revisits, readmissions, duration of surgery and length of hospital stay. Results: 2889 patients underwent a primary bariatric procedure in a single center. There was a significant decrease in minor complications over the years from 7.0 to 1.9% (p < 0.001). Hospital revisit rates decreased after 2015 (p < 0.001). Readmission rates decreased over time (p < 0.001). The mean duration of surgery decreased from 52 (in 2014) to 41 (in 2017) minutes (p < 0.001). Median length of hospital stay decreased from 1.8 to 1.5 days in 2015 (p = 0.002) and remained stable since. Conclusion: An improvement of the ERABS protocol was associated with a decrease in minor complication rates, number of unplanned hospital revisits and readmission rates after primary bariatric procedures
The Influence of Surgical Experience on Postoperative Recovery in Fast-Track Bariatric Surgery
Introduction: Short duration of surgery is an important aspect in fast-track protocols. Peroperative training of surgical residents could influence the duration of surgery, possibly affecting patient outcome. This study evaluates the influence of the operator’s level of experience on patient outcome in fast-track bariatric surgery. Methods: Data was analyzed of all patients who underwent a primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) between January 2004 and July 2018. Residents were trained according to a stepwise training program. For each operator, learning curves of both procedures were created by dividing the procedures in time-subsequent groups (TSGs). Data was also analyzed by comparing “beginners” with “experienced operators,” with a cut-off point at 100 procedures. Primary outcome measure was duration of surgery. Secondary outcome measures were length of hospital stay (LOS), complications, and readmission rate within 30 days postoperatively. Results: There were 4901 primary procedures (53.1% LSG) performed by seven surgeons or surgical residents. We found no difference between beginning and experienced operators in complications or readmissions rates. The experience of the operator did not influence LOS (p = 0.201). Comparing each new operator with previous operator(s), the starting point in terms of duration of surgery was shorter, and thcorresponding author at Franciscus Gasthuis & Vlietland Rotterda
Quality of Life 1 Year After Laparoscopic Sleeve Gastrectomy Versus Laparoscopic Roux-en-Y Gastric Bypass: a Randomized Controlled Trial Focusing on Gastroesophageal Reflux Disease
Introduction: Bariatric surgery is the only treatment option that achieves sustained weight loss in obese patients and that also has positive effects on obesity-related comorbidities. Laparoscopic sleeve gastrectomy (LSG) seems to achieve equal weight loss as laparoscopic Roux-en-Y gastric bypass (LRYGB), but there is still much debate about the quality of life (QOL) after LSG, mainly concerning the association with gastroesophageal reflux. Our hypothesis is that QOL after LSG is comparable with QOL after LRYGB. Materials and Methods: Between February 2013 and February 2014, 150 patients were randomized to undergo either LSG or LRYGB in our clinic. Differences in QOL were compared between groups by using multiple QOL questionnaires at follow-up moments preoperatively and 2 and 12 months after surgery. Results: After 12 months of follow-up, 128 patients had returned the questionnaires. Most QOL questionnaires showed significant improvement in scores between the preoperative moment and after 12 months of follow-up. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) score deteriorated in the LSG group after 2 months, but recovered again after 12 months. After 2 months of follow-up, the mean GerdQ score was 6.95 ± 2.14 in the LSG group versus 5.50 ± 1.49 in the LRYGB group (p < 0.001). After 1 year, the mean GerdQ score was 6.63 ± 2.26 in the LSG group and 5.60 ± 1.07 in the LRYGB group (p = 0.001). Conclusion: This randomized controlled trial shows that patients who underwent LSG have significantly higher GerdQ scores at both 2 and 12 months postoperatively than patients who underwent LRYGB, whereas overall QOL did not differ significantly
Conversion to below-elbow cast after 3 weeks is safe for diaphyseal both-bone forearm fractures in children
Background It is unclear whether it is safe to convert above-elbow cast (AEC) to below-elbow cast (BEC) in a child who has sustained a displaced diaphyseal both-bone forearm fracture that is stable after reduction. In this multicenter study, we wanted to answer the question: does early conversion to BEC cause similar forearm rotation to that after treatment with AEC alone? Children and methods Children were randomly allocated to 6 weeks of AEC, or 3 weeks of AEC followed by 3 weeks of BEC. The primary outcome was limitation of pronation/supination after 6 months. The secondary outcomes were re-displacement of the fracture, limitation of flexion/extension of the wrist and elbow, complication rate, cast comfort, complaints in daily life, and cosmetics of the fractured arm. Results 62 children were treated with 6 weeks of AEC, and 65 children were treated with 3 weeks of AEC plus 3 weeks of BEC. The follow-up rate was 60/62 and 64/65, respectively with a mean time of 6.9 (4.7-13) months. The limitation of pronation/supination was similar in both groups (18 degrees for the AEC group and 11 degrees for the AEC/BEC group). The secondary outcomes were similar in both groups, with the exception of cast comfort, which was in favor of the AEC/BEC group. Interpretation Early conversion to BEC cast is safe and results in greater cast comfort
Laparoscopic sleeve gastrectomy with an extensive posterior mobilization: Technique and preliminary results
Background: Laparoscopic sleeve gastrectomy (LSG) is becoming increasingly popular as a stand-alone procedure for the treatment of morbidly obese patients. A direct posterior approach to the angle of His was developed at our department to improve visualization of the difficult dissection of the short gastric vessels and to facilitate proper mobilization of the stomach around the left crus enabling safe realization of a tight sleeve. The technique and its preliminary results are described. Methods: LSG by posterior approach was performed in a consecutive series of 445 (110 male/335 female, age 18-63 years, mean body mass index 46 kg/m2 (range 35-76)) patients between 2007 and 2010. Results: Weight loss defined as mean percent excess weight loss (%EWL) was 71% (±26%) at 1 year, 69% (±25%) at 2 years, and 55% (±27%) at 3 years. Sixteen patients (4%) developed postoperative intra-abdominal hematoma, 8 patients (2%) anastomotic leakage, and 6 patients intra-abdominal abscess (1%), requiring reoperation in 20 patients (4%). Five patients (1%) had pulmonary embolism. Thirty-day mortality rate was 0.2%. Conclusions: LSG by the posterior approach is a safe and effective procedure, enabling a tight sleeve formation leading to satisfactory %EWL results. Since long-term results of LSG are unknown, further studies are needed to define the exact place of the LSG as a stand-alone bariatric proc
Pulmonary Function Testing and Complications of Laparoscopic Bariatric Surgery
__Abstract__
__Background__:
Obesity is associated with respiratory symptoms and impaired pulmonary function, which could increase the risk of complications after bariatric surgery. The purpose of this study is to assess the relationship between pulmonary function parameters before, and the risk of complications after, laparoscopic bariatric surgery. Methods: This prospective study included patients (age 18-60, BMI >35 kg/m2), who were eligible for bariatric surgery. Spirometry was performed in all patients. Complications up to 30 days after bariatric surgery were recorded. Results: Four hundred eighty-five patients were included (304 laparoscopic sleeve gastrectomy, 181 laparoscopic gastric bypass). There were 53 complications (8 pulmonary, 27 surgical, 14 infectious, 4 other) in 50 patients (10 %). There were 35 re-admissions (7.2 %), and 17 re-laparoscopies (3.5 %). Subjects with and without complications did not differ significantly with respect to demographics, weight, BMI, abdominal circumference or fat percentage. Subjects with complications had a significantly lower mean FEV1(mean 86.9 % predicted) and FVC (95.6 % predicted) compared to patients without complications (95.9 % predicted, p = 0.005, and 100.1 % predicted, p = 0.045, respectively). After adjustment for age, gender, BMI, and smoking, abnormal spirometry value remained the single predictive covariable of postoperative complications: FEV1/FVC <70 % adjusted OR 3.1 (95%CI 1.4-6.8, p = 0.006) and ΔFEV1≥12 % adjusted OR 2.9 (95 %CI 1.3-6.6, p = 0.010). Conclusions: The risk of pulmonary complications after laparoscopic bariatric surgery is low. However, subjects with abnormal spirometry test results have a threefold risk of complications after laparoscopic bariatric surgery. Preoperative pulmonary function testing might be useful to predict the risk of complications of laparoscopic bariatric surgery
Contribution of Type 2 Diabetes Mellitus to Subclinical Atherosclerosis in Subjects with Morbid Obesity
Introduction: Type 2 diabetes mellitus (T2DM) and obesity are both related to increased risk of cardiovascular disease and mortality. Early atherosclerotic vascular changes can be detected by non-invasive tests like carotid artery intima-media thickness (cIMT) and pulse wave velocity (PWV). Both cIMT and PWV are significantly impaired in T2DM patients and in obese patients, but the additional effect of T2DM on these vascular measurements in obese subjects has not been evaluated. Methods: Two hundred morbidly obese patients with or without T2DM were enrolled in a prospective cohort study and underwent extensive laboratory testing, including cIMT and PWV measurements. The cohort was divided into a group with and a group without T2DM. Results: Within this cohort, 43 patients (21.5%) were diagnosed with T2DM. These patients were older and had more often (a history of) hypertension as compared to patients without T2DM. HbA1c levels were significantly increased, while LDL cholesterol was significantly lower and the use of statins higher than in non-diabetic participants. cIMT and PWV were significantly increased in subjects suffering from T2DM. The variability in cIMT and PWV was related to differences in age and systolic blood pressure, but not to the presence of T2DM. Conclusion: While T2DM negatively affects the vasculature in morbid obesity, hypertension and age seem to be the major risk factors, independent from the presence of T2DM.

Subclinical cardiac dysfunction in obesity patients is linked to autonomic dysfunction: findings from the CARDIOBESE study
Aims: Obesity doubles the lifetime risk of developing heart failure. Current knowledge on the role of obesity in causing cardiac dysfunction is insufficient for optimal risk stratification. The aim of this study was first to estimate the prevalence of subclinical cardiac dysfunction in obesity patients and second to investigate the underlying pathophysiology. Methods and results: The CARDIOBESE study is a cross-sectional multicentre study of 100 obesity patients [body mass index (BMI) ≥ 35 kg/m2] without known cardiovascular disease and 50 age-matched and gender-matched non-obese controls (BMI ≤ 30 kg/m2). Echocardiography was performed, blood samples were collected, and a Holter monitor was affixed. Fifty-nine obesity patients [48 (42–50) years, 70% female] showed subclinical cardiac dysfunction: 57 patients had decreased global longitudinal strain (GLS), and two patients with normal GLS had either diastolic dysfunction or increased brain natriuretic peptide (BNP). Only one non-obese control had diastolic dysfunction, and none had another sign of cardiac dysfunction. Multivariable logistic analysis identified male gender and standard deviation of all NN intervals (SDNN) index, which is a measure of autonomic dysfunction, as independent significant risk factors for subclinical cardiac dysfunction in obesity patients. Conclusions: There was a high prevalence (61%) of subclinical cardiac dysfunction in obesity patients without known cardiovascular disease, which appeared to be best identified by GLS. Subclinical cardiac dysfunction in obesity was linked to autonomic dysfunction and male gender, and not to the presence of traditional cardiac risk factors, increased C-reactive protein, increased BNP, increased high-sensitivity troponin I, or increased left ventricular mass
Cross-sectional and prospective follow-up study to detect early signs of cardiac dysfunction in obesity: Protocol of the CARDIOBESE study
Introduction In view of the increasing occurrence of both obesity and heart failure, a growing overlap of these two clinical entities in the near future is expected. Significant advances in our understanding of the pathophysiological consequences of obesity for the cardiovascular system have been made over the past two decades. However, to optimise management and treatment of obesity patients, further research is required to improve early identification of cardiac dysfunction in obesity and to gain insight in the underlying pathophysiology. The CARdiac Dysfunction In OBesity - Early Signs Evaluation (CARDIOBESE) study has been designed to address these issues. Methods and analysis CARDIOBESE is a cross-sectional multicentre study of 100 obesity patients scheduled for bariatric surgery (body mass index (BMI) ≥35 kg/m 2) without known cardiovascular disease, and 50 age-matched and gender-matched non-obese controls (BMI <30 kg/m 2). Echocardiography, blood and urine biomarkers and Holter monitoring will be used to identify parameters that are able to show cardiac dysfunction at a very early stage in obesity patients (primary objective). Furthermore, a prospective follow-up study of obesity patients before and 1 year after bariatric surgery will be done to gain insight in the pathophysiology of obesity causing cardiac dysfunction (secondary objective). Ethics and dissemination The study was approved by the Medical Ethics Committee Toetsingscommissie Wetenschappelijk Onderzoek Rotterdam e.o. (TWOR). Inclusion of patients and controls is almost complete. Analyses of the investigations are currently being performed, and dissemination through peer-reviewed publications and conference presentations is expected from the first quarter of 2019. By identifying early markers of cardiac dysfunction in obesity, and by understanding the underlying pathophysiology of the abnormalities of these markers, the CARDIOBESE study may provide guidance for risk stratification, monitoring and treatment strategies for obesity patients
