Optimization of ERCP Technique to Improve the Sensitivity of Biliary Brushing: A Systematic Review and Meta-analysis.

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) with brush cytology is an important tool in the diagnosis of hepatobiliary malignancies. However, reported sensitivity of brush cytology is suboptimal and differs markedly per study. The aim of this study is to analyze the optimal technique of endobiliary brushing during ERCP. METHODS: A systematic review and meta-analysis according was performed using Pubmed, Embase and Cochrane library, and reported reported according to the PRISMA guidelines. The intervention reported should involve ERCP, performed by the endoscopist with a comparison of different brushing techniques. The primary outcome was sensitivity for malignancy. Studies published up to December 2022 were included. Percutaneous techniques and cytological or laboratory techniques for processing of material were excluded. Bias was assessed using the Quadas-2 tool. Pooled sensitivity rates and Forest plots were analyzed for the primary outcome. RESULTS: A total of 16 studies were included. Three studies reported on brushing before or after dilation of a biliary stricture. No improvement in sensitivity was found. Five studies reported on alternative brush designs. This did not lead to improved sensitivity. Seven studies reported on the aspiration and analysis of bile fluid, which resulted in a 16% increase in sensitivity (95% CI 4-29%). One study reported an increased in the number of brush passes to the stricture, providing an increase in sensitivity of 20%. Substantial heterogeneity between studies was found, both methodological and statistical. CONCLUSIONS: Increasing the number of brush-passes and sending bile fluid for cytology increases the sensitivity of biliary brushings during ERCP. Dilation before brushing or alternative brush designs did not increase sensitivity.

Active surveillance in renal transplant patients with prostate cancer: a multicentre analysis.

INTRODUCTION: Due to medical improvements leading to increased life expectancy after renal transplantation and widened eligibility criteria allowing older patients to be transplanted, incidence of (low-risk) prostate cancer (PCa) is increasing among renal transplant recipients (RTR). It remains to be established whether active surveillance (AS) for PCa represents a safe treatment option in this setting. Therefore, we aim to compare AS discontinuation and oncological outcomes of AS for PCa of RTR vs. non-transplant patients. METHODS: Multicentre study including RTR diagnosed with PCa between 2008 and 2018 in whom AS was initiated. A subgroup of non-RTR from the St. Antonius hospital AS cohort was used as a control group. Comparison of RTR vs. non-RTR was performed by 2:1 propensity score matched survival analysis. Outcome measures included tumour progression-free survival, treatment-free survival, metastasis rates, biochemical recurrence rates and overall survival. Patients were matched based on age, year of diagnosis, PSA, biopsy ISUP grade group, relative number of positive biopsy cores and clinical stage. RESULTS: A total of 628 patients under AS were evaluated, including 17 RTRs and 611 non-RTRs. A total of 13 RTR cases were matched with 24 non-RTR cases. Median overall follow-up for the RTR and non-RTR matched cases was, respectively, 5.1 (IQR 3.2-8.7) years and 5.7 (IQR 4.8-8.1) years. There were no events of metastasis and biochemical recurrence among matched cases. The matched-pair analysis results in a 1-year and 5-year survival of the RTR and non-RTR patients were, respectively, 100 vs. 92%, and 39 vs. 76% for tumour progression, 100 vs. 91% and 59 vs. 76% for treatment-free survival and, respectively, 100 vs. 100% and 88 vs. 100% for overall survival. No significant differences in tumour progression-free survival (p = 0.07) and treatment-free survival were observed (p = 0.3). However, there was a significant difference in overall survival comparing both groups (p = 0.046). CONCLUSIONS: AS may be carefully considered in RTR with low-risk PCa. In our preliminary analysis, no major differences were present in AS outcomes between RTR and non-RTR. Overall mortality was significantly higher in the RTR subgroup.

Evaluation of Serum Biomarker CEA and Ca-125 as Immunotherapy Response Predictors in Metastatic Non-small Cell Lung Cancer.

BACKGROUND/AIM: Treatment options for advanced non-small cell lung cancer (NSCLC) include immunotherapy. Elevated carcinoembryonic antigen (CEA) and cancer antigen 125 (Ca-125) levels are associated with poorer prognoses of resected NSCLC, but currently no predictive biomarkers exist for immunotherapy response. This study evaluated CEA and Ca-125 as predictive biomarkers for immunotherapy efficiency in patients with metastatic NSCLC. PATIENTS AND METHODS: The single-centre observational retrospective study includes NSCLC stage III/IV patients treated with programmed death-ligand 1 (PD-L1) inhibitors nivolumab or pembrolizumab. The primary study endpoint was treatment response assessed by CT-scan following RECIST-criteria 1.1. CEA/Ca-125 serum values were determined at initiation of treatment and repeated every 2 weeks. Values closest to the day of CT-scan were compared to baseline values. RESULTS: A total of 136 patients were treated with mono-immunotherapy. Of these, 73 patients were included in the CEA group and 53 patients were included in the Ca-125 group. Baseline CEA and Ca-125 ranged from 8.14 to 5,909 and 1.1 to 4,238 respectively. The sensitivity for Ca-125 as predictor for tumor response was 62.9% (95% CI=61.8%-63.6%), specificity 61.1% (95% CI=60.2%-62.0%), with a positive predictive value (PPV) of 75.9% (95% CI=75.2%-76.7%). For CEA, the sensitivity was 72.0% (95% CI=71.5%-72.5%), specificity 47.1% (95% CI 46.4%-47.8%), with a PPV of 80.0% (95% CI=79.6%-80.4%). CONCLUSION: Increased serum CEA might predict tumor progression in NSCLC patients treated with PD-L1 inhibitors. Unconfirmed progression accompanied by increased CEA would support discontinuation of the immunotherapy, while continuation would be advised when serum CEA is not increased.

Evaluation of Ureteroenteric Anastomotic Strictures after the Introduction of Robot-Assisted Radical Cystectomy with Intracorporeal Urinary Diversion: Results from a Large Tertiary Referral Center.

PURPOSE: Benign ureteroenteric anastomotic strictures following radical cystectomy are a critical complication. The incidence is highly dependent on study design, surgical technique and surgeon experience. We studied the incidence of ureteroenteric anastomotic strictures after open vs robot-assisted radical cystectomy with an intracorporeal urinary diversion, and determined the influence of the introduction of robot-assisted radical cystectomy in our clinic. MATERIALS AND METHODS: A retrospective, single center, cohort study was performed between January 2012 and December 2017 in all patients undergoing radical cystectomy. Multivariate analysis was performed to determine which patient or disease-specific factors were associated with development of ureteroenteric anastomotic strictures. RESULTS: Of 279 patients, 192 (69%) underwent open radical cystectomy and 87 (31%) underwent robot-assisted radical cystectomy with intracorporeal urinary diversion. In total, 47/279 patients (17%) developed ureteroenteric anastomotic strictures after a median of 3.0 months (95% CI 2.4-3.7). The difference in incidence of ureteroenteric anastomotic strictures was statistically significant between open and robot-assisted radical cystectomy (13% vs 25%, p <0.001). On multivariate analysis, only surgical technique (open vs robot-assisted radical cystectomy) was independently associated with development of ureteroenteric anastomotic strictures (p=0.004). There was a peak incidence of ureteroenteric anastomotic strictures after robot-assisted radical cystectomy of 47% during the first year after introduction of the robot-assisted procedure. CONCLUSIONS: Introducing robot-assisted radical cystectomy with intracorporeal urinary diversion can result in an initial peak incidence of strictures, highlighting the importance of surgeon experience and the presence of a learning curve. Nonetheless, after experience has been gained, our results show that patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion are still more likely to develop ureteroenteric anastomotic strictures compared to those undergoing open radical cystectomy.

Open surgical repair of post-dissection thoraco-abdominal aortic aneurysms: early and late outcomes of a single-centre study involving over 200 patients.

OBJECTIVES: Chronic, post-dissection thoraco-abdominal aortic aneurysms (TAAAs) are increasingly being treated by (hybrid) endovascular means. Although it is less invasive, thoracic endovascular aortic repair is technically complex with the risk of incomplete aneurysm exclusion, necessitating frequent reinterventions with potentially reduced long-term outcomes. The aim of this study was to evaluate contemporary early and late outcomes after open surgical repair of post-dissection TAAA. METHODS: At our centre, 633 patients underwent open repair for TAAA over a 20-year period (1994-2015), including 217 (34%) patients for post-dissection TAAA, who were included in this analysis. Circulatory support was obtained by either left heart bypass (173 patients, 79.7%), deep hypothermic circulatory arrest (41 patients, 18.9%) or simple aortic cross-clamping in 3 patients. We analysed all relevant perioperative and intraoperative variables with respect to adverse outcomes. Additionally, long-term survival and the need for aortic reinterventions were studied. RESULTS: The mean age was 60.2 ± 11.9 years (men 68.2%). We identified 66 Type I (30.4%), 113 Type II (52.1%), 25 Type III (11.5%), 10 Type IV (4.6%) and 3 Type V (1.4%) TAAAs. Early mortality and spinal cord deficit were 5.9% and 5.5%, respectively. Follow-up was 100% complete (mean 6.0 ± 5.8 years), with long-term survival of 71.4% at 10 years, and freedom from death and reoperation was 68.2% at 10 years. CONCLUSIONS: Although it is more invasive than current endovascular approaches for post-dissection TAAA, open surgical repair can be performed safely with acceptable rates of morbidity and mortality when it is done in a specialized aortic centre. Long-term survival and freedom from aortic reintervention are excellent and should also be taken into account when evaluating less invasive alternatives.

Open thoracoabdominal aortic aneurysm repair in the modern era: results from a 20-year single-centre experience.

OBJECTIVES: The efficacy and durability of actual treatments (open, endovascular and hybrid) for thoracoabdominal aortic aneurysm (TAAA) repair are not yet completely defined. Open surgical repair using a multi-adjunct (ADJ) approach has been the standard of care for many years and may still be an effective treatment option. This study aimed to assess the outcomes of open TAAA repair since the introduction of the available ADJ. METHODS: From 1994 to 2014, 542 consecutive patients underwent open TAAA repair in our institution, routinely receiving aortic distal perfusion and the other ADJ (either for visceral and spinal cord protection). The aetiology of TAAA was identified to be degenerative in 325 (60%) patients and chronic post-dissection in 160 (29.5%) patients. Other causes such as connective tissue disorders, vasculitis and infective aneurysms were less represented (10.5%). Extensive type I and II repair was required in 128 (23.6%) and 285 (52.6%) patients, respectively. All patients were followed up at 3 and 6 months after surgery and yearly thereafter using computed tomography angiogram. RESULTS: The overall 30-day mortality and paraplegia rates were 8.5 and 4.2%, respectively. Age [odds ratio (OR) 1.07 per year, 95% confidence interval (CI) 1.02-1.13], female gender (OR 2.52, 95% CI 1.27-4.99), urgency (OR 2.78, 95% CI 1.12-6.20) and emergency (OR 3.81, 95% CI 1.00-11.50) emerged as independent risk factors for 30-day mortality. Follow-up was 100% complete (mean 6.32 years). Overall 1-, 5- and 10-year survival was 85.9 ± 1.5, 74.2 ± 2.0 and 61.6 ± 2.5%, respectively. The extent of surgical repair did not significantly influence late hospital death (P = 0.56). For patients surviving the first 30 days, a degenerative aneurysm aetiology negatively impaired long-term survival compared with the other diseases [hazard ratio = 1.66; 95% CI (1.13-2.44)]. Five- and 10-year freedom from reoperation was 86.3 ± 1.8 and 80.7 ± 2.3%, respectively, and 8.5% of patients required aortic reinterventions. CONCLUSIONS: In elective cases, open TAAA repair has to be considered an effective option associated with low necessity of reoperation at follow-up. The extent of aortic resection did not affect long-term mortality. Conversely, survival was mainly determined by patient age and preoperative condition.

Comparison of Warm Blood Cardioplegia Delivery With or Without the Use of a Roller Pump.

Various techniques for administration of blood cardioplegia are used worldwide. In this study, the effect of warm blood cardioplegia administration with or without the use of a roller pump on perioperative myocardial injury was studied in patients undergoing coronary artery bypass grafting using minimal extra-corporeal circuits (MECCs). Sixty-eight patients undergoing elective coronary bypass surgery with an MECC system were consecutively enrolled and randomized into a pumpless group (PL group: blood cardioplegia administration without roller pump) or roller pump group (RP group: blood cardioplegia administration with roller pump). No statistically significant differences were found between the PL group and RP group regarding release of cardiac biomarkers. Maximum postoperative biomarker values reached at T1 (after arrival intensive care unit) for heart-type fatty acid binding protein (2.7 [1.5; 6.0] ng/mL PL group vs. 3.2 [1.6; 6.3] ng/mL RP group, p = .63) and at T3 (first postoperative day) for troponin T high-sensitive (22.0 [14.5; 29.3] ng/L PL group vs. 21.1 [15.3; 31.6] ng/L RP group, p = .91), N-terminal pro-brain natriuretic peptide (2.1 [1.7; 2.9] ng/mL PL group vs. 2.6 [1.6; 3.6] ng/mL RP group, p = .48), and C-reactive protein (138 [106; 175] µg/mL PL group vs. 129 [105; 161] µg/mL RP group, p = .65). Besides this, blood cardioplegia flow, blood cardioplegia line pressure, and aortic root pressure during blood cardioplegia administration were similar between the two groups. Administration of warm blood cardioplegia with or without the use of a roller pump results in similar clinically acceptable myocardial protection.

Mechanochemical endovenous ablation versus radiofrequency ablation in the treatment of primary small saphenous vein insufficiency (MESSI trial): study protocol for a randomized controlled trial.

BACKGROUND: Minimally invasive endothermal techniques, for example, radiofrequency ablation (RFA), have revolutionized the treatment of insufficient truncal veins and are associated with an excellent outcome. The use of thermal energy requires the instillation of tumescent anesthesia around the vein. Mechanochemical endovenous ablation (MOCA™) combines mechanical endothelial damage, using a rotating wire, with simultaneous infusion of a liquid sclerosans. Tumescent anesthesia is not required as no heat is used. Prospective studies using MOCA™ in both great and small saphenous veins showed good anatomical and clinical results with fast postoperative recovery. METHODS/DESIGN: The MESSI trial (Mechanochemical Endovenous ablation versus radiofrequency ablation in the treatment of primary Small Saphenous vein Insufficiency) is a multicenter randomized controlled trial in which a total of 160 patients will be randomized (1:1) to MOCA™ or RFA. Consecutive patients with primary small saphenous vein incompetence, who meet the eligibility criteria, will be invited to participate in this trial. The primary endpoint is anatomic success, defined as occlusion of the treated veins objectified with duplex ultrasonography at 1 year follow-up. Secondary endpoints are post-procedural pain, initial technical success, clinical success, complications and the duration of the procedure. Initial technical success is defined as the ability to position the device adequately, treat the veins as planned and occlude the treated vein directly after the procedure has been proven by duplex ultrasonography. Clinical success is defined as an objective improvement of clinical outcome after treatment, measured with the Venous Clinical Severity Score (VCSS). Power analyses are conducted for anatomical success and post-procedural pain.Both groups will be evaluated on an intention-to-treat principle. DISCUSSION: The hypothesis of the MESSI trial is that the anatomic success rate of MOCA™ is not inferior to RFA. The second hypothesis is that post-procedural pain is significantly less after MOCA compared to RFA. TRIAL REGISTRATION: NTR4613 Date of trial registration: 28 May 2014.

Can late supraclavicular echo Doppler reliably predict angiographical string sign of lima to lad area grafts?

OBJECTIVE: To investigate whether supraclavicular ultrasonography of left internal mammary artery (LIMA) to left anterior descending (LAD) area grafts can reliably predict (distal) string sign grafts on arteriography. METHODS: Fifty-five patients (42 M, 61 +/- 7 years) with the LIMA to LAD area grafting were prospectively studied. Control arteriography was performed at 1.4 +/- 0.8 years postoperatively. Angiography demonstrated in 46 patients (group I) functional grafts, in 4 patients (group II) sequential distal string sign grafts and in 5 patients (group III) total string sign grafts. Ultrasonography was performed at 1.8 +/- 0.8 year postoperatively and compared with control angiography. Data were tested by unpaired t- and ANOVA tests. The diagnostic accuracy was assessed by the area under the curve of the Receiver Operator Characteristic. A formula was developed to predict the probability of (distal) string sign phenomena of sequential as well as single LIMA grafts. RESULTS: Between the groups all duplex parameters showed a highly significant linear relation (p < or = 0.004) and all parameters between group I and III are significantly different with high Area Under Curve values. The model for the probability of (distal) string sign grafts fitted best with diastolic and systolic peak velocities as the most discriminative factors for (distal) string sign grafts. CONCLUSIONS: Postoperative supraclavicular duplex as a method to assess the patency of LIMA to LAD area grafts allows discriminating functional grafts from (distal) string sign grafts.

Renal function after endovascular aortic aneurysm repair: a single-center experience with transrenal versus infrarenal fixation.

PURPOSE: To describe the short-term consequences of endovascular aortic aneurysm repair (EVAR) on renal function after infrarenal (IR) versus transrenal (TR) stent-graft fixation. METHODS: Between December 1996 and January 2006, 369 consecutive patients were treated with EVAR. All patients had an AneuRx or a Talent stent-graft implanted using IR (AneuRx) or transrenal (Talent) fixation. Post-EVAR, a standardized follow-up scheme included computed tomography (CT) scanning and serum creatinine measurements at 2 days, 3 months, and 12 months. Postoperative renal dysfunction was defined as a >20% decrease in serum creatinine clearance compared to baseline, the presence of new-onset dialysis, or both. Of the 369 patients, 309 (291 men; mean age 71+/-7 years, range 63-82) had complete 1-year follow-up and were included in this study. An IR stent-graft was placed in 190 patients, and a TR stent-graft was placed in the remaining 119 patients. RESULTS: At discharge, renal dysfunction occurred in 3.7% of the patients in the IR group versus 5.9% in the TR group (p = NS) and rose significantly to 13.7% in the IR group (p = 0.001) and 15.1% in the TR group (p = 0.02) at the 1-year follow-up. However, no significant difference was noted between the IR and TR groups at either time point. At the 1-year follow-up, at least 50% of renal dysfunction was caused by obstructions of (accessory) renal arteries and renal infarctions. During the follow-up interval, 3 (0.97%) of 309 patients underwent new-onset dialysis. CONCLUSION: Both infrarenal and transrenal fixation techniques in EVAR will lead to a significant rise in renal dysfunction during the first year. A few patients with dysfunction will require dialysis.

Preserved hyperaemic response in (distal) string sign left internal mammary artery grafts.

OBJECTIVE: To correlate supraclavicular ultrasonography at rest and in hyperaemic response with angiographically patent and (distal) 'string sign' left internal mammary artery (LIMA) to left anterior descending (LAD) area grafts. METHODS: Fifty-three patients with LIMA to LAD area grafting were prospectively entered in a follow-up study. Arteriography (native and LIMA) was performed at 1.4+/-0.8 years postoperatively and ultrasonography was performed at rest, in hyperaemic response and 2min after hyperaemic response at 1.8+/-0.8 years postoperatively and was compared to arteriography. Ultrasonographic parameters analysed were systolic and diastolic peak velocity, systolic and diastolic velocity integral, diastolic/systolic peak velocity ratio and diastolic/total velocity integral ratio. RESULTS: One patient was excluded because obesity hampered ultrasonography. Arteriography demonstrated functional grafts in 43 patients (group I), sequential distal 'string sign grafts' in 4 patients (group II) and total 'string sign grafts' in 5 patients (group III). Between the groups all ultrasonographic velocities showed a significant linear relation (p

Surgery for acute type A aortic dissection: is advanced age a contraindication?

BACKGROUND: With the general increase in human lifespan, cardiac surgeons are faced with treating an increasing number of elderly patients. The purpose of this study was to demonstrate early and late results of surgery for aortic dissection in patients older than 70 years of age compared with those younger than 70 years and to clarify the clinical problems related to this subset of patients. METHODS: Between 1976 and 2001, 315 patients underwent emergency operation for acute type A dissection: 245 were younger than 70 years (group 1) and 70 patients were 70 years of age and older (group 2). Early and late outcomes of both groups were compared. RESULTS: The hospital mortality rates were 20.5% in group 1 and 17.6% in group 2 (p = 0.751). The mean extracorporeal circulation time was 192.6 +/- 65.2 minutes and 185.7 +/- 58.4 minutes in groups 1 and 2, respectively (p = 0.42). The mean cross-clamp time was 116.3 +/- 45.8 minutes and 100 +/- 36.7 minutes in groups 1 and 2, respectively (p = 0.009). Actuarial survival rates were 77.1% after a mean follow-up time of 259 +/- 9 months for patients of group 1 and 80% after 77 +/- 5 months for patients of group 2, without any statistically significant difference (p = 0.619). CONCLUSIONS: No significant differences were observed in the 30-day mortality and actuarial survival between the two groups. Therefore we believe that surgery for type A acute aortic dissection in patients 70 years of age or older can be performed with acceptable risk of death and satisfactory results.

Introduction of adjuncts and their influence on changing results in 402 consecutive thoracoabdominal aortic aneurysm repairs.

OBJECTIVE: To assess the influence of adjuncts, cerebrospinal fluid drainage (CSFD) and evoked potentials, on morbidity and mortality after thoracoabdominal aortic aneurysm (TAAA) repair and to update our experience. METHODS: Between February 1981 and February 2003, 402 consecutive patients underwent repair of their TAAA using simple cross-clamping between 1981 and 1994 (n = 123; CC), left heart bypass (from 1987; n = 254) or extracorporeal circulation (n = 25; ADJ). Somatosensory evoked potentials were used in 264 patients and motor evoked potentials in 176 patients. CSFD was used in 202 patients (50.2%). RESULTS: Overall hospital mortality was 10.9:14.1% in the CC-group versus 9.1% in the ADJ-group (P = 0.07). The incidence of postoperative dialysis was 6.1%. Paraplegia and paraparesis together was found in 11.3%. Independent risk factors for hospital mortality were age (OR 1.1 per year, 95% CI 1.04-1.16), rupture (OR 3.8, 95% CI 1.7-8.8) and postoperative hemodialysis (OR 8.1, 95% CI 3.2-20.3). For postoperative hemodialysis the risk factors were age >/=75 years (OR 3.2, 95% CI 1.1-9.7), a preoperative creatinine level higher than 150 microM/l (OR 6.5, 95% CI 2.6-16.2), and as a protective factor operation performed after 1995 (OR 0.2, 95% CI 0.06-0.6). For spinal cord dysfunction (paraplegia and paraparesis together) the protective factors were age >/=75 years (OR 0.16, 95% CI 0.02-1.2), operation performed after 1995 (OR 0.31, 95% CI 0.15-0.65) and a previous aortic dissection (OR 0.38, 95% CI 0.15-0.9). CONCLUSIONS: The use of different adjuncts introduced over the years clearly influenced our results in a positive way.

High-dose aspirin in addition to daily low-dose aspirin decreases platelet activation in patients before and after percutaneous coronary intervention.

BACKGROUND: Activated platelets play a major role in acute vessel closure after coronary angioplasty. Although aspirin is the routine therapy during angioplasty, it only incompletely prevents acute closure. This might be due to suboptimal dosing. OBJECTIVE: First, to study the effect of additional high-dose aspirin on platelet activation during coronary angioplasty. Second, to assess the potential of the new PFA-100 analyzer to evaluate the effect of different doses of aspirin in patients undergoing angioplasty. METHODS: Fifty-one patients on 100 mg aspirin/day for at least 1 month were randomized to continuation of 100 mg aspirin/day only (Group A=24 patients), or to this regime plus a bolus of 1000 mg of aspirin given 1 day before angioplasty (Group B=27 patients). Results were compared with 15 controls. Platelet function was measured before angioplasty by the PFA-100 analyzer; platelet activation was measured by flow cytometry just before and 1 h after angioplasty. RESULTS: At baseline, Group A had significantly more activated platelets than the control group (P<.001). High-dose aspirin in Group B resulted in significantly lower platelet activation as compared with both controls (P<.001) and Group A (P<.001). During angioplasty, the number of activated platelets decreased significantly in Group A (P<.001), while there was no change in Group B (P=.6). The PFA-100 analyzer was unable to detect differences between the two treatment groups. CONCLUSIONS: The addition of high-dose aspirin to daily low-dose aspirin, 1 day before coronary angioplasty, significantly reduced the platelet activation state before and after intervention. The PFA-100 analyzer did not detect differences in the effect of low- versus high-dose aspirin on platelet function.

Eating patterns in morbidly obese patients before and after a gastric restrictive operation.

BACKGROUND: The present study was set up to analyze the relationships between eating patterns in morbidly obese patients who had undergone an adjustable silicone gastric banding (ASGB) followed for at least 2 years and morbidly obese patients without a gastric restrictive procedure. METHODS: Eating pattern was monitored by using the Dutch Eating Behavior Questionnaire in 99 morbidly obese patients (BMI > or = 35 kg/m2) preoperatively and in 31 patients who had undergone a stomach reduction by the Lap-Band followed at least 2 years. Both groups were compared to the Dutch normative scores. RESULTS: In the preoperative group, the scores on emotional eating and external eating were significantly higher than the Dutch normative scores. The scores on restrained eating were preoperatively equal to the Dutch normative scores. Although not significant, the scores in the postoperative group on external eating were lower than the Dutch normative scores and equal on emotional eating. The variable restrained eating postoperatively was significantly higher compared with the preoperative group. On emotional and external eating, the scores postoperatively were significantly lower compared with the preoperative group. CONCLUSIONS: According to the results, surgical treatment using an ASGB or another gastric restrictive operation could be the right solution in patients with an emotional and external eating behavior. Placement of the ASGB has a negative effect on restrained eating behavior.

Coping behavior and loneliness among obese patients.

BACKGROUND: Morbid obesity can be accompanied by physical and social problems that may influence interpersonal relationships and the recruitment of social support. The problems can be tackled with a variety of coping strategies. METHODS: 104 patients with a body mass index (BMI) 32-64 kg/m2 and mean age 36 yr were presented with the Utrecht Coping List (UCL) and the Loneliness Scale. Of these patients, 94 were female, and this cohort was analyzed more extensively. RESULTS: Patients exhibited elevated values on the Loneliness Scale and in the UCL sub-scales palliative response, avoidance / wait-and-see, passive / depressive response pattern and expression of emotions / anger. The active approach UCL sub-scale scored lower than in a control group. CONCLUSION: Obese female patients displayed avoidance, wait-and-see and passive response pattern as coping behavior, experiencing their intimate relationships as relatively unreliable and not very intimate. More research is needed to determine the effect of coping behavior on therapeutic effect.
