  • Stereotactic Surgery on a female patient with severe chronic anorexia nervosa: 10-year follow-up.
    Eating and weight disorders : EWD, 2019
    Co-Authors: Fabiola Guerrero Alzola, José Casas Rivero, Roberto Martínez-Álvarez
    Abstract:

    Anorexia nervosa (AN) is a serious disease with a high rate of chronification. In chronic and serious cases, psychotherapeutic and pharmacological treatments are not sufficient to control the disease. We present the case of a female patient with severe chronic restrictive anorexia nervosa resistant to psychomedical treatment. During the 31 years the illness evolved, the patient required multiple hospital admissions. With a body mass index (BMI) of 12.8 kg/m2 and consequent risk of death, Stereotactic cingulotomy was performed comprising bilateral blocking of the anterior cingulate cortex by Stereotactic radiofrequency thermocoagulation, confirmed by tractography 5 years later. After 10 years of follow-up, the patient is clinically stable with an increased BMI and improved neuropsychological indicators. Stereotactic Surgery may be an option for patients with chronic anorexia nervosa where conventional treatments have proved insufficient.

    Abstract:

    Introduction Anorexia nervosa (AN) is a serious disease with a high rate of chronification. In chronic and serious cases, psychotherapeutic and pharmacological treatments are not sufficient to control the disease. Case report We present the case of a female patient with severe chronic restrictive anorexia nervosa resistant to psychomedical treatment. During the 31 years the illness evolved, the patient required multiple hospital admissions. With a body mass index (BMI) of 12.8 kg/m^2 and consequent risk of death, Stereotactic cingulotomy was performed comprising bilateral blocking of the anterior cingulate cortex by Stereotactic radiofrequency thermocoagulation, confirmed by tractography 5 years later. After 10 years of follow-up, the patient is clinically stable with an increased BMI and improved neuropsychological indicators. Discussion Stereotactic Surgery may be an option for patients with chronic anorexia nervosa where conventional treatments have proved insufficient.

  • Clinical application of robotic tele-manipulation system in Stereotactic Surgery
    Zhonghua wai ke za zhi [Chinese journal of surgery], 2007
    Co-Authors: Zeng-min Tian, Tianmiao Wang, Quanjun Zhao, Guo-lai Zhang, Du Liu, Yan Chen, Mang-mang Bai, Feng Yin
    Abstract:

    OBJECTIVE To assess the clinical usefulness, accuracy, and safety of tele-manipulation for frameless Stereotactic Surgery using the CAS-R-5 robot system. METHODS We prospectively evaluated 32 patients underwent tele-manipulation of frameless Stereotactic operations from Sep. 2005 to Sep. 2006. Tele-manipulations were performed via a digital data network by a neurosurgeon in Beijing while the patients were located in Yan'an. The distance is 1300 kilometers away. The accuracy of location and improvement of symptom were observed after operation. The period of follow-up was from 3 to 14 months (the average was 12 months). RESULTS The surgical operations in 32 cases were successful. Remote fiducial registration was performed with a mean accuracy of 1. 50 mm and the standard difference were 0.32 mm between the planned and actual target. There were no complications. CONCLUSIONS Diagnosis and treatment for intracranial disease by tele-manipulation frameless Stereotactic surgeries are reliable and safe.

  • treatment of intractable anorexia nervosa with inactivation of the nucleus accumbens using Stereotactic Surgery
    Stereotactic and Functional Neurosurgery, 2013
    Co-Authors: Jing Wang, Xuelian Wang, Chongwang Chang, Ning Geng, Guodong Gao
    Abstract:

    Background: For 30% of anorexia nervosa (AN) patients, conventional treatments are unsuccessful; this is termed intractable AN. Objectives: This study investigates whether ablation of the nucleus accumbens (NAc) using Stereotactic Surgery can arouse the physiological drive to eat in intractable AN patients. Methods: Eight patients with intractable AN were included: 6 patients underwent bilateral Stereotactic radio frequency ablation in the NAc and 2 patients received bilateral NAc deep brain stimulation (DBS). Observations were made for basic vital signs, body mass index (BMI), menstruation, depression, anxiety, obsessive-compulsive disorder, personality, intelligence, memory, quality of life, social functioning, as well as complications and adverse events associated with the treatment. Results: Basic vital signs, BMI and menstruation had recovered 1 year after the operation. Depression, anxiety and obsessive-compulsive disorder were improved 1 year postoperatively. There were changes in personality scores for psychoticism, neuroticism and lie tendencies that seemed to be helpful to the recovery from AN. Intelligence and memory improved after 6 months postoperatively. Quality of life and social functioning were dramatically improved at 1 year postoperatively. Conclusions: The results of this study reveal that ablation of the NAc can increase the AN patients' physiological drive to eat. Furthermore, there were no severe and/or life-influencing complications associated with the treatment.

  • Preliminary findings in ablating the nucleus accumbens using Stereotactic Surgery for alleviating psychological dependence on alcohol
    Neuroscience letters, 2010
    Co-Authors: Xuelian Wang, Chongwang Chang, Li Gao, Ning Geng, Wei Zhao, Guodong Gao
    Abstract:

    Abstract We studied the effect of Stereotactic Surgery in cases of alcohol dependence. Twelve patients with a psychological dependence on alcohol (treated systematically with medication for detoxification 3–8 times in various rehabilitation centers before, but had relapsed within 2 weeks after withdrawal) were treated by ablating the nucleus accumbens (NA C ) bilaterally using Stereotactic Surgery. The therapeutic effect and safety evaluation index of the Surgery were analyzed. The timing of the conducted evaluations was preoperatively and in the sixth postoperative month. Currently, relapse has not occurred in 9 cases. Relapse occurred in 3 cases after Surgery. The prevalence of relapse was 16.7% within 6 months, and 25% within 12 months. Non-specific complications of this type of Surgery (e.g., intracranial hematoma, infection) were not observed. One case in 12 patients suffered dysosmia, but he recovered completely 4 months later after Surgery. The full-scale intelligence quotient (FSIQ) and memory quotient (MQ) of these patients were significantly improved 6 months postoperatively compared with preoperatively. The severity of alcohol dependence scale and a scale measuring alcohol craving in these patients were significantly decreased. There were also significant changes over time in the Minnesota multiphasic personality inventory (MMPI) profile, suggesting a decrease in depression, irritability, and psychopathy. Ablating specified targets (NA C ) using Stereotactic Surgery is a safe method to alleviate alcohol craving, reduce relapse rates and improve quality-of-life in patients with psychological dependence on alcohol.
