Article: Psychiatric disorders of patients seeking obesity treatment.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Obese and overweight people have a higher risk of both chronic physical illness and mental illness. Obesity is reported to be positively associated with psychiatric disorders, especially in people who seek obesity treatment. At the same time, obesity treatment may be influenced by psychological factors or personality characteristics. This study aimed to understand the prevalence of mental disorders among ethnic Chinese who sought obesity treatment. METHODS: Subjects were retrospectively recruited from an obesity treatment center in Taiwan. The obesity treatments included bariatric surgery and non-surgery treatment. All subjects underwent a standardized clinical evaluation with two questionnaires and a psychiatric referral when needed. The psychiatric diagnosis was made thorough psychiatric clinic interviews using the SCID. A total of 841 patients were recruited. We compared the difference in psychiatric disorder prevalence between patients with surgical and non-surgical treatment. RESULTS: Of the 841 patients, 42% had at least one psychiatric disorder. Mood disorders, anxiety disorders and eating disorders were the most prevalent categories of psychiatric disorders. Females had more mood disorders and eating disorders than males. The surgical group had more binge-eating disorder, adjustment disorder, and sleep disorders than the non-surgical group. CONCLUSION: A high prevalence of psychiatric disorders was found among ethnic Chinese seeking obesity treatment. This is consistent with study results in the US and Europe.BMC Psychiatry 01/2013; 13(1):1. · 2.55 Impact Factor -
Article: Randomized controlled trial comparing three methods of liver retraction in laparoscopic Roux-en-Y gastric bypass.

ABSTRACT: BACKGROUND: This study aimed to evaluate differences between three methods of liver retraction during laparoscopic Roux-en-Y Gastric bypass (LRYGB) and to compare novel liver retraction techniques with the traditional mechanical liver retractor in a randomized controlled trial. METHODS: In this study, 60 obese patients (26 males and 34 females) who underwent LRYGB between January and July 2010 were randomized to one of three groups (20 in each): group 1 (Nathanson liver retractor), group 2 (liver suspension tape), and group 3 (V-shaped liver suspension technique [V-LIST]). Data regarding demographics (age, sex, body mass index); liver function test (LFT) just before surgery; postoperative results immediately, then 18 h, 1 week, and 1 month after surgery; operative data, and visual analog scale (VAS) for pain on postoperative days (PODs) 1 and 2 were calculated and analyzed. RESULTS: The groups did not differ significantly in terms of preoperative LFT or operative data except that group 3 took significantly longer time for liver suspension than group 1 (p = 0.01) or group 2 (p = 0.03). The VAS score in group 2 was significantly lower on POD 1 than in group 1 (p = 0.04). Group 1 showed a significant rise in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) at 18 h compared with group 2 (p < 0.01 and p = 0.02, respectively) and group 3 (p < 0.01 and p = 0.01), at 1 week compared with group 2 (p = 0.04 and 0.04), and in AST levels alone during the immediate postoperative compared with group 3 (p = 0.04). CONCLUSION: The Nathanson liver retractor causes more liver dysfunction than V-LIST or the liver suspension technique and causes more postoperative pain than the liver suspension technique. Both V-LIST and liver suspension tape have a short learning curve and implications for single-port surgery.Surgical Endoscopy 07/2012; · 4.01 Impact Factor
