    Background: Gastric banding (GB) is one of the most popular bariatric procedures for morbid obesity. Apart from causing weight loss by alimentary restriction, it can interfere with functions of the esophagus and upper stomach. The aim of this study was to evaluate if the results of extensive preoperative upper GI testing were correlated with long-term outcome and complications after GB. Methods: Using a prospectively maintained computerized database including all the patients undergoing bariatric operations in both our hospitals, we performed a retrospective analysis of the patients who underwent complete upper gastrointestinal (GI) testing (endoscopy, pH monitoring, and manomatry) before GB. Results: One hundred thirty-four patients underwent complete testing before GB. Abnormal pH monitoring (increased total reflux time, increased diurnal reflux time, increased number of reflux episodes) predicted the development of complications and especially pouch dilatation and food intolerance. The mean De Meester score was higher among patients who developed complications than in the remaining ones (25.4 vs 17.7, P = 0.03). High lower esophageal sphincter pressure also predicted progressive long-term food intolerance. Endoscopic findings were not predictive of the long-term outcome. Conclusions: There is some association between the function of the upper digestive tract and long-term complications after gastric banding. Abnormal pH monitoring predicts overall long-term complications, especially food intolerance with or without reflux, and pouch dilatation, and a high lower esophageal sphincter pressure predicts long-term food intolerance. Extended upper gastrointestinal testing with endoscopy, 24-h pH monitoring, and esophageal manometry is probably worthwhile in selecting patients for gastric bandin

    Background: Bariatric surgery is often associated with reduced food tolerance and sometimes frequent vomiting, which influence quality of life, but are not included in the overall evaluation of these procedures, notably the BAROS. Our aim was to develop a simple questionnaire to evaluate food tolerance during follow-up visits. Methods: A one-page questionnaire including questions about overall satisfaction regarding quality of alimentation, timing of eating over the day, tolerance to several types of food, and frequency of vomiting/ regurgitation was developed. A composite score was derived from this questionnaire, giving a score of 1 to 27.Validation was performed with a group of nonobese adults and a group of morbidly obese nonoperated patients. Patients were administered the questionnaire at follow-up visits since January 1999. Data were collected prospectively. Results: It takes 1-2 minutes to fill out the questionnaire. Food tolerance is worse in the morbidly obese population compared with non-obese adults (24.2 vs 25.2, P=0.004). Following Roux-en-Y gastric bypass, food tolerance is reduced after 3 months (21.2), but becomes comparable to that of the normal population and remains so at 1year postoperatively. Following gastric banding, food tolerance is already significantly reduced after 3months (22.3), and worsens continuously over time (19.03 after 7years). In the gastric banding population, the decision to adjust the band is based at least partially on food tolerance, and the questionnaire proved helpful in that respect. Conclusion: Our new questionnaire proved very easy to use, and helpful in day-to-day practice, especially after gastric banding. It was also helpful in comparing food tolerance over time after surgery, and in comparing food tolerance between procedures. Evaluation of food tolerance should be part of the overall evaluation of the results after bariatric surger

    Roux-en-Y gastric bypass (RYGBP) is one of the most commonly performed bariatric procedures for morbidly obese patients. It is associated with effective long-term weight loss, but can lead to significant complications, especially at the gastrojejunostomy (GJS). All the patients undergoing laparoscopic RYGBP at one of our two institutions were included in this study. The prospectively collected data were reviewed retrospectively for the purpose of this study, in which we compared two different techniques for the construction of the GJS and their effects on the incidence of complications. In group A, anastomosis was performed on the posterior aspect of the gastric pouch. In group B, it was performed across the staple line used to form the gastric pouch. A 21-mm circular stapler was used in all patients. A total of 1,128 patients were included between June 1999 and September 2009—639 in group A and 488 in group B. Sixty patients developed a total of 65 complications at the GJS, with 14 (1.2%) leaks, 42 (3.7%) strictures, and 9 (0.8%) marginal ulcers. Leaks (0.2% versus 2%, p = 0.005) and strictures (0.8% versus 5.9%, p < 0.0001) were significantly fewer in group B than in group A. Improved surgical technique, as we propose, with the GJS across the staple line used to form the gastric pouch, significantly reduces the rate of anastomotic complications at the GJS. A circular 21-mm stapler can be used with a low complication rate, and especially a low stricture rate. Additional methods to limit complications at the GJS are probably not routinely warrante

    Recurrent Left Colonic Diverticulitis Episodes: More Severe Than the Initial Diverticulitis?

    Background: Until recently, it was accepted that the rate of complications and failure of medical therapy were higher during recurrent episodes of diverticulitis. New data and new interpretation of older studies have challenged this opinion. The aim of the present study was to determine whether recurrent diverticulitis in comparison with the initial episode has a different short-term outcome after medical or surgical treatment. Methods: This was a retrospective cohort study of 271 consecutive patients admitted for diverticulitis confirmed by computed tomography (CT) between 2001 and 2004. Altogether 202 patients had an initial episode (group I), and 69 had recurrent diverticulitis (group R). A total of 20 clinical and 15 radiologic parameters were analyzed and compared between the two groups, including need for surgery, clinical presentation at admission, response to treatment, complications, laboratory parameters, and pathologic CT features (colonic wall thickening, abscess, pneumoperitoneum, free intraperitoneal fluid). An unpaired Student's t-test and Fisher's and Wilcoxon's tests were applied for statistical analysis. Results: None of the clinical or radiologic parameters was statistically different between the two groups. Regarding surgery, 15.8% of the group I patients needed surgery at admission compared to 5.8% in group R (p=0.04). Conservative treatment failure was similar in the two groups (10.7% vs. 10.0%; p=0.84). There was 3% mortality at 30days in group I compared to 0% in group R. Conclusions: Recurrent episodes of diverticulitis do not lead to more complications and more conservative treatment failure. Moreover, surgery at admission was less frequent among patients who presented with a recurrenc

    BACKGROUND: Asthmatics and patients with chronic obstructive pulmonary disease (COPD) have more severe outcomes with viral infections than people without obstructive disease. OBJECTIVE: To evaluate if obstructive diseases are risk factors for intensive care unit (ICU) stay and death due to coronavirus disease 2019 (COVID19). METHODS: We collected data from the electronic medical record from 596 adult patients hospitalized in University Hospital of Liege between March 18 and April 17, 2020, for severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection. We classified patients into 3 groups according to the underlying respiratory disease, present before the COVID19 pandemic. RESULTS: Among patients requiring hospitalization for COVID19, asthma and COPD accounted for 9.6% and 7.7%, respectively. The proportions of asthmatics, patients with COPD, and patients without obstructive airway disease hospitalized in the ICU were 17.5%, 19.6%, and 14%, respectively. One-third of patients with COPD died during hospitalization, whereas only 7.0% of asthmatics and 13.6% of patients without airway obstruction died due to SARS-CoV2. The multivariate analysis showed that asthma, COPD, inhaled corticosteroid treatment, and oral corticosteroid treatment were not independent risk factors for ICU admission or death. Male gender (odds ratio [OR]: 1.9; 95% confidence interval [CI]: 1.1-3.2) and obesity (OR: 8.5; 95% CI: 5.1-14.1) were predictors of ICU admission, whereas male gender (OR 1.9; 95% CI: 1.1-3.2), older age (OR: 1.9; 95% CI: 1.6-2.3), cardiopathy (OR: 1.8; 95% CI: 1.1-3.1), and immunosuppressive diseases (OR: 3.6; 95% CI: 1.5-8.4) were independent predictors of death. CONCLUSION: Asthma and COPD are not risk factors for ICU admission and death related to SARS-CoV2 infection

    Age at onset as stratifier in idiopathic Parkinson’s disease – effect of ageing and polygenic risk score on clinical phenotypes

    Several phenotypic differences observed in Parkinson’s disease (PD) patients have been linked to age at onset (AAO). We endeavoured to find out whether these differences are due to the ageing process itself by using a combined dataset of idiopathic PD (n = 430) and healthy controls (HC; n = 556) excluding carriers of known PD-linked genetic mutations in both groups. We found several significant effects of AAO on motor and non-motor symptoms in PD, but when comparing the effects of age on these symptoms with HC (using age at assessment, AAA), only positive associations of AAA with burden of motor symptoms and cognitive impairment were significantly different between PD vs HC. Furthermore, we explored a potential effect of polygenic risk score (PRS) on clinical phenotype and identified a significant inverse correlation of AAO and PRS in PD. No significant association between PRS and severity of clinical symptoms was found. We conclude that the observed non-motor phenotypic differences in PD based on AAO are largely driven by the ageing process itself and not by a specific profile of neurodegeneration linked to AAO in the idiopathic PD patients

    Roux-en-y Gastric Bypass is Superior to Gastric Banding in Non-superobese Patients. a Matched-case Study with Five-year Follow-up

    Background: Roux-en-Y gastric bypass (RYGBP) and gastric banding (GB) are the two most popular bariatric procedures. Only few studies have compared their results and follow-up duration is usually limited to &lt;3 years. Patients and Methods: Using our prospective bariatric database, we matched non-superobese GB to RYGBP patients for sex, age and BMI to RYGBP. Follow-up considered up to five years. Results: 442 patients were matched in 221 pairs. Mean age (38,6) and mean BMI (43) were identical. Overall operative morbidity was higher after RYGBP (17,2 versus 5,4 %, p&lt;0,001), but major morbidity was similar (3,6 versus 2,2 %, p=0,57). More patients developed long-term complications after GB (43,9 % versus 19 %, p&lt;0,001), and more required reoperations (24,4 % versus 12 %, p=0,001). After RYGBP, reoperations were mainly due to internal hernias (87 %), with no reversal, whereas 18,5 % of the GB patients required band removal. Even including only patients who retained their band, weight loss after RYGBP was better throughout the study period, with 5-year EBMIL of 77,6 % and 61,7 % (p&lt;0,001) after RYGBP and GB respectively. RYGBP was associated with better food tolerance and greater improvement of the lipid profile. Conclusions: GB is associated with a smaller overall operative morbidity and similar major morbidity, but with more long-term complications, more reoperations, a significant number of reversal or conversion procedures, and reduced weight loss when compared with RYGBP. Five-year results of RYGBP are superior to GB and patients should be informed accordingly

    Rapid Improvement and Maintenance of the Lipid Profile After Roux-en-Y Gastric Bypass (RYGBP)

    Background: Dyslipidemia, a major component of the metabolic syndrome and an important cardiovascular risk factor, is one of the commonest comorbidity associated with morbid obesity. The aim of this paper is to show that RYGBP markedly improves dyslipidemia and that this improvement maintains over time. Patients and Methods: Prospectively updated databank for bariatric patients. Patients undergoing RYGBP have yearly blood tests during follow-up. The results for lipids at one to five years were compared with preoperative values. Results: The mean excess BMI loss after one and five years was 77,9 % and 72,3%respectively. After one year, there was a significant reduction of the mean total cholesterol, LDL-cholesterol, total cholesterol/HDL ratio and triglyceride values, which maintained up to five years, and an increase of the HDL fraction, which progressed until five years. The proportion of patients with abnormal values decreased from 24,3 to 6,2% for total cholesterol, from 45,1 to 11,7 %for HDL, from 53,3 to 21,9 for LDL, and from 40,5 to 10 % for triglycerides, with no significant change between three and five years, despite some weight regain. Conclusions: RYGBP rapidly improves all components of dyslipidemia, and thereby reduces the overall cardiovascular risk in operated patients

    Laparoscopic Gastric Banding: A Prospective, Randomized Study Comparing the Lapband and the SAGB: Early Results

    No full text
    OBJECTIVE: The objective of this study was to evaluate the results of laparoscopic gastric banding using 2 different bands (the Lapband [Bioenterics, Carpinteria, CA] and the SAGB [Swedish Adjustable Gastric Band; Obtech Medical, 6310 Zug, Switzerland]) in terms of weight loss and correction of comorbidities, short-and long-term complications, and improvement of quality of life in morbidly obese patients SUMMARY BACKGROUND DATA: During the past 10 years, gastric banding has become 1 of the most common bariatric procedures, at least in Europe and Australia. Weight loss can be excellent, but it is not sufficient in a significant proportion of patients, and a number of long-term complications can develop. We hypothesized that the type of band could be of importance in the outcome. METHODS: One hundred eighty morbidly obese patients were randomly assigned to receive the Lapband or the SAGB. All the procedures were performed by the same surgeon. The primary end point was weight loss, and secondary end points were correction of comorbidities, early- and long-term complications, importance of food restriction, and improvement of quality of life. RESULTS: Initial weight loss was faster in the Lapband group, but weight loss was eventually identical in the 2 groups. There was a trend toward more early band-related complications and more band infections with the SAGB, but the study had limited power in that respect. Correction of comorbidities, food restriction, long-term complications, and improvement of quality of life were identical. Only 55% to 60% of the patients achieved an excess weight loss of at least 50% in both groups. There was no difference in the incidence of long-term complications. CONCLUSIONS: Gastric banding can be performed safely with the Lapband or the SAGB with similar short- and midterm results with respect to weight loss and morbidity. Only 50% to 60% of the patients will achieve sufficient weight loss, and close to 10% at least will develop severe long-term complications
