Mood disorders in laparoscopic sleeve gastrectomy patients: does it affect early weight loss?
ABSTRACT Research has demonstrated that laparoscopic Roux-en-Y gastric bypass patients with a lifetime history of a mood disorder have a lower percentage of excess weight loss (%EWL) compared with patients without this lifetime history. No studies have examined the effect of psychiatric history on postoperative outcomes among laparoscopic sleeve gastrectomy (LSG) patients. The objectives of the present study were to determine whether mood disorders relate to the first year of weight loss for patients undergoing LSG at an academic medical center.
A total of 104 patients (78.6% white and 71.2% women), with a median body mass index of 60.35 kg/m(2) (range 31.37-129.14) underwent LSG. The patients were prospectively followed up at 1, 3, 6, 9, and 12 months. The semistructured preoperative psychiatric evaluations demonstrated that 43.1% had a current, and 62.5% a lifetime, diagnosis of a mood disorder.
LSG patients with current mood disorders had a significantly lower %EWL than patients without a psychiatric diagnosis at the 1-, 3-, 6-, and 9-month follow-up visits. LSG patients with a lifetime history of a mood disorder had a significantly lower %EWL than patients without psychiatric diagnosis at the 1-, 9-, and 12-month follow-up examinations. However, after removing patients with bipolar disorder from the analyses, no significant differences were found in the %EWL between patients with and without a lifetime history of depressive disorders.
Consistent with the laparoscopic Roux-en-Y gastric bypass findings, a lifetime history of mood disorders appears to be associated with significantly less weight loss in LSG patients. These findings highlight the importance of the psychiatric assessment in bariatric patients. Additionally, patients with a current or lifetime history of mood disorders might need additional pre- and postoperative care to improve their outcomes.

ABSTRACT: Laparoscopic gastric bypass (GBP) is becoming a common approach for treatment of morbid obesity. We analyzed preoperative factors that may be associated with operative outcomes in laparoscopic GBP. This prospective study evaluates 150 consecutive laparoscopic GBP procedures performed by a single surgeon. Preoperative factors were grouped into three categories: 1) patient-specific (gender, age, abdominal surgical history, smoking), 2) obesity-specific (body mass index, hypertension, diabetes, sleep apnea), and 3) procedure-specific (operative experience of the surgeon [75 cases or less versus more than 75 cases]). Length of operation (240 minutes or less versus more than 240 minutes), postoperative complications (yes versus no), major complications (yes versus no), reoperation (yes versus no), and length of hospital stay (4 days or less versus more than 4 days) were the operative outcomes considered. In this series all patients who had a major complication required a reoperation. Data were analyzed using univariate and multiple logistic regression analyses. Operative experience of surgeon (75 cases or less) was associated with lengthy operative time (adjusted odds ratio [AOR], 3.8; 95% confidence interval [CI], 1.7 to 8.3), major complications (AOR, 15.0; 95% CI, 1.5 to 143.0), and a lengthy (more than 4 days) hospital stay (AOR, 4.5; 95% CI, 1.1 to 18.0). Higher patient age (50 years or more) was associated with more postoperative complications (AOR, 11.4; 95% CI, 3.0 to 43.1) and major complications (AOR, 7.6; 95% CI, 1.1 to 48.7). Male gender also was associated with more postoperative complications (AOR 5.2; 95% CI, 1.1 to 23.1). Obesity-related comorbidities, body mass index, past abdominal surgical history, and smoking had no statistical association with operative outcomes in this study. There is an association of clinical outcomes after laparoscopic GBP with the age and gender of the patient and the operative experience of the surgeon. An operative experience of more than 75 laparoscopic GBP cases was associated with decreases in operative time, length of hospital stay, and number of major complications.Journal of the American College of Surgeons 11/2003; 197(4):548-55; discussion 555-7. · 4.50 Impact Factor

ABSTRACT: Because of the possibility of being denied or delayed surgery, bariatric patients might have a motivation to minimize any emotional difficulties in the preoperative psychological evaluation. This study examined changes in the psychometric test scores when extremely defensive patients were asked to repeat the testing. Changes in the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scale scores were studied in a subsample of patients referred to the author for a preoperative psychological evaluation. After producing defensive MMPI-2 test profiles, these bariatric patients (n = 31) were provided feedback on their defensiveness and asked to be more open and honest on the repeat testing. The vast majority (94%) of the patients produced valid profiles on the second test. On the second test, significant differences were found on 6 of the 13 MMPI-2 scales, as well as on separate measures of depression, anxiety, and anger. It appears to be important to include a psychometric measure that includes a validity scale in the evaluation process, because patients might be motivated to present in a defensive or overly virtuous light in fear that a negative evaluation from the psychologist would adversely affect a decision regarding their candidacy for surgery. It is recommended that patients who are defensive in their testing be asked to repeat the test battery.Surgery for Obesity and Related Diseases 01/2007; 3(2):184-8. · 4.12 Impact Factor

ABSTRACT: Gastric restrictive surgery induces a marked change in eating behavior. However, the relationship between preoperative and postoperative eating behavior and weight loss outcome has received limited attention. This study assessed a range of eating behaviors before and 1 year after laparoscopic adjustable gastric banding (LAGB) and explored the nature and extent of change in eating patterns, their clinical associates, and impact on weight loss. A 12-month observational study assessed presurgical and postsurgical binge eating disorder (BED), uncontrolled eating, night eating syndrome (NES), grazing, nutrient intake and eating-related behaviors, and markers of psychological distress. A total of 129 subjects (26 male and 103 female, mean age 45.2 +/- 11.5 and BMI 44.3 +/- 6.8) participated in this study. Presurgical BED, uncontrolled eating, and NES occurred in 14%, 31%, and 17.1% of subjects, which reduced after surgery to 3.1%, 22.5%, and 7.8%, respectively (P = 0.05 for all). Grazing was prevalent before (26.3%) and after surgery (38.0%). Preoperative BED most frequently became grazers (P = 0.029). The average percentage weight loss (%WL) was 20.8 +/- 8.5%; range -0.67 to 50.0% and percentage of excess weight loss (%EWL) 50.0 +/- 20.7%; range -1.44 to 106.9% (P < 0.001). Uncontrolled eating and grazing after surgery showed high overlap and were associated with poorer %WL (P = 0.008 and P < 0.001, respectively) and elevated psychological distress. Consistent with recent studies, uncontrolled eating and grazing were identified as two high-risk eating patterns after surgery. Clearer characterization of favorable and unfavorable postsurgical eating behaviors, reliable methods to assess their presence, and empirically tested postsurgical intervention strategies are required to optimize weight loss outcomes and facilitate psychological well-being in at-risk groups.Obesity 03/2008; 16(3):615-22. · 3.92 Impact Factor
