Behavioral Outcomes Following Laparoscopic Sleeve Gastrectomy Performed After Failed Laparoscopic Adjustable Gastric Banding

Risk of Delayed Discharge and Reoperation of Gastric Bypass Patients with Psychiatric Comorbidity-a Nationwide Cohort Study

BACKGROUND

Gastric bypass (GBP) surgery is considered a safe and effective treatment for obesity. However, there is uncertainty regarding the impact of preexisting psychiatric comorbidity on GBP complications. We have investigated whether a psychiatric diagnosis before GBP surgery is associated with delayed discharge (the odds of being in the 90th percentile of length of stay) and rate of reoperation in a nationwide Swedish cohort.

METHODS

Patients undergoing GBP surgery during 2008-2012 were identified and followed up through the National Patient Register and the Prescribed Drug Register. Logistic regression models were fitted to the studied outcomes.

RESULTS

Among the 22,539 patients identified, a prior diagnosis of bipolar disorder, schizophrenia, depression, neurotic disorders, ADHD (attention deficit hyperactivity disorder), substance use disorder, eating disorder, personality disorder, or self-harm since 1997 (n = 9480) was found to be associated with delayed discharge after GBP surgery (odds ratio [OR] = 1.47, confidence interval [CI] 1.34-1.62), especially in patients with psychiatric hospitalization exceeding 1 week in the 2 years preceding GBP surgery (OR = 2.06, CI 1.30-3.28), compared with those not hospitalized within psychiatry. Likewise, patients with a prior psychiatric diagnosis were more likely to be reoperated within 30 days (OR = 1.25, CI 1.11-1.41), with twice the likelihood OR 2.23 (CI 1.26-3.92) for patients with psychiatric hospitalization of up to a week in the 2 years preceding GBP surgery, compared with patients who had not been hospitalized within psychiatry.

CONCLUSIONS

A psychiatric diagnosis before GBP surgery was associated with delayed discharge and increased likelihood of reoperation within 30 days. Patients with a prior psychiatric diagnosis may, therefore, need additional attention and support.

Psychological and Behavioral Aspects of Primary and Reoperative Surgery: a 6-Month Longitudinal Study

BACKGROUND

Problematic eating behaviors and general psychopathology have been associated with poor weight loss after bariatric surgery. However, little is known about how these aspects impact weight loss outcomes for the increasing number of patients undergoing reoperative surgeries. This study compares disordered eating and weight-related outcomes before and 6 months after surgery in patients undergoing primary (P-Group) and reoperative bariatric surgery (R-Group).

METHODS

This longitudinal study assessed 122 P-Group and 116 R-Group patients before and 6 months after surgery. The assessment included the eating disorder examination diagnostic items, and a set of self-report measures assessing eating disorder symptomatology, grazing, depression, anxiety, and negative urgency.

RESULTS

Preoperatively, no differences were found between the R- and P-Groups in terms of disordered eating-related variables (except for shape concern, which was higher for the R-Group). At 6 months after surgery, the R-Group revealed significantly higher values for restraint (F(1,219) = 5.84, p = 0.016), shape (F(1,219) = 5.59, p = 0.019), weight concerns (F(1,219) = 13.36, p = 0.000), depression (F(1,219) = 7.17, p = 0.008), anxiety (F(1,219) = 6.94, p = - 0.009), and compulsive grazing (F(1,219) = 6.13, p = 0.014). No significant pre- or post-surgery predictors of weight loss were found for the P-Group (χ2 = 0.70, p = 0.872). In the R-Group, post-surgery anxiety (Waldχ²(1) = 6.19, p = 0.01) and the post-surgery number of days with grazing in the previous month (Waldχ²(1) = 3.90, p = 0.04) were significant predictors of weight loss.

CONCLUSION

At 6 months after surgery, the R-Group presented more problematic eating and general psychological distress, which may put these patients at greater risk of poorer long-term weight outcomes.

APOLO-Bari, an internet-based program for longitudinal support of bariatric surgery patients: study protocol for a randomized controlled trial

Background

Despite evidence of successful weight loss for bariatric surgery patients, some patients experience considerable weight regain over the long term. Given the strong association between post-surgery health behaviors and outcomes, aftercare intervention to address key behaviors appears to be a reasonable relapse-prevention strategy. As the burden of obesity rates increases in healthcare centers, an internet-based program appears to be a reasonable strategy for supporting bariatric surgery patients in the long term. The primary purpose of the current project is to develop and test the efficacy and perceived utility of APOLO-Bari.

Methods/design

This study is a randomized control trial, which will be conducted in two hospital centers in the North of Portugal; it includes a control group receiving treatment as usual and an intervention group receiving the APOLO-Bari program for one year in addition to treatment as usual. A total of 180 male and female participants who underwent bariatric surgery (gastric sleeve or gastric bypass surgery) for 12 to 20 months will be recruited. Both groups will complete a similar set of questionnaires at baseline, every 4 months until the end of the intervention, and at 6 and 12 months follow-up. Assessment includes anthropometric variables and psychological self-report measures. The primary outcome measure will be weight regain measured at the end of treatment, and at 6 and 12 months follow-up. The secondary aims are to test the cost-effectiveness of the intervention and to investigate psychological predictors and trajectories of weight regain. APOLO-Bari was developed to address the weight regain problem in the bariatric population by offering additional guidance to bariatric patients during the postoperative period. The program includes: (a) a psychoeducational cognitive-behavioral-based self-help manual, (b) a weekly feedback messaging system that sends a feedback statement related to information reported by the participant, and (c) interactive chat sessions scheduled with a trained psychologist in the field.

Discussion

APOLO-Bari may play an important role in broadening therapeutic reach to bariatric patients who would not otherwise have continuous support, with important implications for public health treatment.

ANALYSIS OF FOOD TOLERANCE IN PATIENTS SUBMITTED TO BARIATRIC SURGERY USING THE QUESTIONNAIRE QUALITY OF ALIMENTATION

BACKGROUND

Due to the increased prevalence of obesity in many countries, the number of bariatric surgeries is increasing. They are considered the most effective treatment for obesity. In the postoperative there may be difficulties with the quality of alimentation, tolerance to various types of food, as well as vomiting and regurgitation. Few surveys are available to assess these difficulties in the postoperative.

AIM

To perform a systematic literature review about food tolerance in patients undergoing bariatric surgery using the questionnaire "Quality of Alimentation", and compare the results between different techniques.

METHOD

A descriptive-exploratory study where the portals Medline and Scielo were used. The following headings were used in english, spanish and portuguese: quality of alimentation, bariatric surgery and food tolerance. A total of 88 references were found, 14 used the questionnaire "Quality of Alimentation" and were selected.

RESULTS

In total, 2745 patients were interviewed of which 371 underwent to gastric banding, 1006 to sleeve gastrectomy, 1113 to Roux-en-Y gastric bypass, 14 to biliopancreatic diversion associated with duodenal switch, 83 were non-operated obese, and 158 non-obese patients. The questionnaire showed good acceptability. The biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to other techniques, but it was evaluated in a single article with a small sample. The longer the time after the operation, the better is the food tolerance. Comparing the sleeve gastrectomy and the Roux-en-Y gastric bypass, there are still controversial results in the literature. The gastric banding had the worst score of food tolerance among all the techniques evaluated.

CONCLUSION

The questionnaire is easy and fast to assess the food tolerance in patients after bariatric surgery. Biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to sleeve gastrectomy and the Roux-en-Y gastric bypass. Gastric banding still remains in controversy, due it presented the worst score.

Five-year weight loss in primary gastric bypass and revisional gastric bypass for failed adjustable gastric banding: results of a case-matched study

BACKGROUND

Despite their now frequent use, the long-term results for adjustable gastric bands are variable and often less than gastric bypass. Laparoscopic Roux-en-Y gastric bypass (LRYGB) provides good early results and seems to be the revisional procedure of choice. Nevertheless, the long-term outcomes following revisional LRYGB (rLRYGB) for failed adjustable gastric banding have not been compared with those for primary LRYGB (pLRYGB).

METHODS

The objective was to compare weight loss and changes in obesity related co-morbidities 5 years after pLRYGB and rLRYGB for failed adjustable gastric banding. The prospective database of a single surgery university center (Paris, France) was queried for clinical and other relevant data. From January 2004 to September 2008, 58 and 272 patients have undergone rLRYGB and pLRYGB, respectively. Rate of lost to follow-up was 13.3%. We matched 45 patients undergoing rLRYGB (case group) with 45 undergoing pLRYGB (control group) for age, sex, and initial body mass index (BMI).

RESULTS

Case and control groups did not differ for initial BMI (46.9±7.2 versus 46.9±7.5 kg/m²; P=.99), age (43.4±9.4 versus 43.6±9.8y; P=.91), or sex ratio (91.1% female, P=.99). The rates of coexisting conditions in the 2 groups were similar. At 5 years, weight loss (kg) (39.9±16.4 versus 31.4±15.8; P=.02), percentage of weight loss (%) (30.8±9.8 versus 24.8±11.5; P=.03), and percentage of excess weight loss (%) (68.4±20.6 versus 55.7±26.3; P=.007) were higher for pLRYGB than rLRYGB. Rates of remission and improvement of coexisting conditions were similar.

CONCLUSION

After 5 years of follow-up, pLRYGB provides greater weight loss than rLRYGB with similar rates of improvement and remission of coexisting conditions. Patients and surgeons should be aware of such results before primary and revisional bariatric surgery.
