Laparoscopic transabdominal preperitoneal hernioplasty for bilateral obturator hernias and left inguinal hernia with emaciation caused by anorexia nervosa: A case report.

A 55-year-old woman receiving treatment for anorexia nervosa presented with abdominal pain and right thigh pain. Her body mass index was 12.9 kg/m2 . Computed tomography showed fluid storage in the distal side of the right obturator foramen and revealed a dilated small bowel without a starting point of obstruction. We diagnosed a naturally reduced incarcerated right obturator hernia and performed elective surgery with a laparoscopic approach for hernia repair the next day. Intraperitoneal observation revealed bilateral obturator hernias and a left direct-type inguinal hernia. Transabdominal preperitoneal hernioplasty was performed using two self-gripping polyester meshes for bilateral obturator hernia repair and a lightweight 3D-shaped mesh for left inguinal hernia repair. Women with emaciation caused by anorexia nervosa may be more likely to have complex hernias, including obturator hernia, and laparoscopic approaches may be useful for preoperatively diagnosed nonstrangulated obturator hernias.

Rescue Anterior Capsulotomy after Failure of Nucleus Accumbens Deep Brain Stimulation in Anorexia Nervosa: A Case Report.

Anorexia nervosa (AN) is a highly disabling mental disorder with high rates of morbidity and mortality. Few psychological treatments and pharmacotherapy are proven to be effective for adult AN. Two invasive stereotactic neurosurgical interventions, deep brain stimulation (DBS) and anterior capsulotomy, are now commonly used as investigational approaches for the treatment of AN. Here, we report the long-term safety and efficacy of rescue bilateral anterior capsulotomy after the failure of bilateral nucleus accumbens (NAcc)-DBS in an 18-year-old female patient with life-threatening and treatment-resistant restricting subtype AN. Improvements in the neuropsychiatric assessment were not documented 6 months after the NAcc-DBS. Rescue bilateral anterior capsulotomy was proposed and performed, resulting in a long-lasting restoration of body weight and a significant and sustained remission in AN core symptoms. The DBS pulse generator was exhausted 2 years after capsulotomy and removed 3 years postoperatively. No relapse was reported at the last follow-up (7 years after the first intervention). From this case, we suggest that capsulotomy could be a rescue treatment for patients with treatment-resistant AN after NAcc-DBS failure. Further well-controlled studies are warranted to validate our findings.

[Functional Neurosurgery for Anorexia Nervosa].

Anorexia nervosa (AN) is a serious psychiatric disorder characterized by disturbances in body- and self-perception and excessive weight loss. AN is sometimes refractory to conventional treatments such as medication and psychological therapy. Therefore, the neurosurgery for psychiatric disorders (NPD) has been studied. While the efficacy of NPD has previously been reported and is currently being studied, it is not performed in Japan. We introduce the results of representative studies that investigated functional neurosurgery for AN. (Received May 22, 2020; Accepted November 20, 2020; Published April 1, 2021).

Deep brain stimulation telemedicine programming during the COVID-19 pandemic: treatment of patients with psychiatric disorders.

OBJECTIVE: The ongoing coronavirus disease 2019 (COVID-19) pandemic has considerably affected the delivery of postoperative care to patients who have undergone deep brain stimulation (DBS) surgery. DBS teleprogramming technology was developed and deployed in China before the COVID-19 outbreak. In this report, the authors share their experiences with telemedical DBS treatment of patients with psychiatric disorders during the COVID-19 outbreak. METHODS: Four patients (2 with obsessive-compulsive disorder, 1 with major depressive disorder, and 1 with anorexia nervosa) underwent DBS surgery at Ruijin Hospital and received continuous postoperative DBS telemedicine case management from January 2020 to July 2020. DBS teleprogramming, individualized psychological support, and medical consultations were provided via the authors' DBS telemedicine platform, which also incorporated a synchronous real-time video communication system. RESULTS: Forty-five DBS telemedicine sessions were conducted; there was no unexpected loss of network connection during the sessions. Of these, 28 sessions involved DBS teleprogramming. Adjustments were made to the stimulation voltage, frequency, pulse width, and contact site in 21, 12, 9, and 9 sessions, respectively. Psychological support and troubleshooting were provided during the remaining telemedicine sessions. Modest to substantial clinical improvements after DBS surgery were observed in some but not all patients, whereas stimulation-related side effects were reported by 2 patients and included reversible sleep and mood problems, headache, and a sensation of heat. CONCLUSIONS: DBS telemedicine seems to offer a feasible, safe, and efficient strategy for maintaining the delivery of medical care to psychiatric patients during the COVID-19 outbreak. The authors propose that implementation of a comprehensive DBS telemedicine system, which combines DBS teleprogramming with psychological counseling, medical consultations, and medication prescriptions and delivery, could be an efficient and effective approach to manage the mental health and quality of life of patients with psychiatric disorders during future local or global public health crises.

Deep brain stimulation for the treatment of severe intractable anorexia nervosa.

Anorexia nervosa (AN) is a challenging multifactorial disorder with the highest mortality rate among all psychiatric disorders. Due to the low rate of long-term treatment success, new treatment options are needed. Here, we review Deep Brain Stimulation (DBS) as a treatment of Severe Intractable AN. The mechanisms of AN have shown significant involvement of the central nervous system especially the same brain regions which are involved with obsessive-compulsive disorder (OCD) and major depressive disorder (MDD). AN and OCD display many similarities in psychiatric practice such as compulsive behaviours and anxiety levels, which are related to networks in the brain, that can be altered using DBS. Our literature search revealed 8 studies totalling 28 individuals with AN and comorbid OCD or MDD. The most common stereotactic targets included the sub-callosal cingulate cortex (Brodmann area 25)/medial forebrain bundle (MFB) for AN and comorbid MDD and nucleus accumbens (NAc)/ventral striatum for AN and comorbid OCD. In most cases bilateral DBS of various structures of the reward system achieved good results in BMI, and core AN symptoms and psychiatric comorbidities showed sustained improvement. DBS is a promising treatment modality for AN and comorbid OCD or MDD. These results highlight promise and hope for patients with AN. However, further studies with larger patient populations are needed to shed light on the long-term outcomes of DBS and its effects in AN treatment.

Radiosurgery for Behavioral Disorders.

Psychiatric illnesses create great suffering for patients and the medical solution is sometimes limited. The experience observed after treating patients with obsessive-compulsive disorder (OCD), depression, and anorexia nervosa by Gamma Knife radiosurgery (GKRS) is presented. Ten patients with medically refractory OCD, 3 patients with depression resistant to medical treatment and electroconvulsive therapy, and 5 patients with refractory anorexia nervosa have been treated. Bilateral anterior capsulotomy has been performed to treat OCD and bilateral cingulotomy has been applied to treat severe depression and anorexia nervosa. The accumulated experience about treatment of OCD by GKRS is reviewed. In our experience, 70% of OCD patients achieved a full response. We observed a significant improvement in patients with depression and anorexia nervosa evidenced by the scales of assessment (mean reduction of 40% in the Beck Depression Inventory at 1-year follow-up and 40% average increase of body mass index at 6-month follow-up). No side effects have been observed. These procedures are effective in reducing obsession, compulsion, depression, and anxiety, improving the quality of life of the patients without side effects.

Long-Term Follow-up Study of MRI-Guided Bilateral Anterior Capsulotomy in Patients With Refractory Anorexia Nervosa.

BACKGROUND: Anorexia nervosa (AN) is one of the most challenging psychiatric disorders to treat. The poor clinical outcomes warrant novel treatments for AN, especially in severe and persistent cases. OBJECTIVE: To explore the feasibility of magnetic resonance imaging-guided bilateral anterior capsulotomy in the treatment of refractory AN. METHODS: Seventy-four patients diagnosed with refractory AN who underwent capsulotomy completed this 3-yr follow-up study. Outcomes included body mass index (BMI) and results from a series of psychiatric scales (for obsessive, depressive, and anxious symptoms) that were implemented at baseline (presurgery), and 1 mo, 1 yr, and 3 yr after surgery. RESULTS: Compared to presurgical levels, BMI increased significantly at 1-yr and 3-yr follow-ups. Compared to presurgery scores, psychiatric scale scores were significantly improved at 1-mo postsurgery, and continued to remain low at the 1-yr and 3-yr follow-ups. In addition, Mini-Mental State Examination (MMSE) scores were in the normal range during the long-term follow-up. The most common short-term side effects included urinary incontinence (n = 7), sleep disorders (n = 8), and fatigue (n = 6). Long-term complications included disinhibition (n = 6), memory loss (n = 3), and lethargy (n = 4). No patient in this study experienced death or disability. CONCLUSION: Capsulotomy enabled patients with refractory AN to normalize their weight, especially those in life-threatening conditions. While it appears to be an acceptable life-saving treatment, it is indicated only when fulfilling strict criteria given its complications and irreversibility.

[Not Available]. / Tratamiento quirúrgico de la anorexia nerviosa resistente al tratamiento médico.

Gracias a los avances técnicos en técnicas neuroquirúrgicas, y debido a que el diagnóstico y la clasificación de las enfermedades psiquiátricas han evolucionado significativamente a lo largo de las últimas décadas, se están desarrollando tratamientos a nivel experimental para aquellos pacientes resistentes al manejo conservador.La anorexia nerviosa es una enfermedad de prevalencia creciente, con la tasa de mortalidad más elevada dentro de los trastornos psiquiátricos, y con aproximadamente un 20% de pacientes que presentan una evolución tórpida. Para estos pacientes que no responden a manejo conservador, la estimulación cerebral profunda ha surgido como una alternativa terapéutica, si bien la literatura especializada al respecto es escasa.A continuación presentamos una revisión de la fisiopatología de la anorexia nerviosa, así como de los distintos tratamientos neuroquirúrgicos realizados a lo largo de la historia. Se detalla la perspectiva de tratamiento quirúrgico actual, así como los aspectos éticos que se han de considerar en relación con el surgimiento de estas nuevas terapias.

Perioperative management of severe anorexia nervosa.

As the prevalence of anorexia nervosa (AN) increased, surgery in severe AN patients also increased in the 2000s. We experienced a surgical case of a patient with severe AN, showing an extremely low BMI of 8.6 kg m(-2). We investigated the problems associated with this case and propose criteria to manage severe AN. We endeavour to report on the perioperative management of rare and severe symptoms and surgical indications of severely malnourished patients. All published reports were identified through comprehensive searches using PubMed, BioMedLib, and the Japan Medical Abstracts Society with the following terms and keywords: 'anorexia nervosa', 'eating disorder', 'hypoglycaemia', 'leucocytopaenia', 'gelatinous bone marrow', 'surgery', and 'operation'. In cases of AN with a BMI under 13 kg m(-2), marked hypoglycaemia, leucocytopaenia <3.0×10(9) litre(-1), or both, potentially fatal complications frequently occur. Accordingly, patients need strict nutritional support to avoid re-feeding syndrome until surgery. During the course of anaesthesia, careless loading of glucose or catecholamine may lead to disturbance of electrolytes or fatal arrhythmia. Intensive care and early feeding as soon as possible after surgery are important to prevent surgical site infection. Although not many perioperative cases of AN have been reported, clinicians must be aware of the danger and the causes of mortality in critical cases. Thus, the decision to undertake surgery must be taken carefully and close perioperative coordination among physicians, surgeons, psychiatrists, anaesthesiologists, and intensivists is essential.

Treatment of intractable anorexia nervosa with inactivation of the nucleus accumbens using stereotactic surgery.

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.

Brain tumors and the area postrema.

Brain tumors can rarely present with symptoms mistaken for anorexia nervosa. We report a patient with a long-standing history of anorexia who developed headaches and was found on brain MRI to have a brain tumor in the area of the fourth ventricle. On admission, the patient presented with a 4 month history of headaches and a 10 year history of "anorexia nervosa". Interestingly, the patient did not endorse the classic sense of an altered self-body image. Her body weight on admission was 37 kg. The patient underwent surgical resection of the tumor. On postoperative day (POD) 1, the patient subjectively reported an increased appetite. On POD 2, we documented that she finished her entire food tray for the first time during her hospital stay. Her peri-operative course was without any complications. She presented for a follow-up clinic visit 2 weeks postoperatively and was noted to have a new body weight of 47 kg (10 kg gain). To our knowledge, this is the first reported occurrence of a sporadic, and third overall occurrence, of a hemangioblastoma that presented with an anorexia nervosa-like syndrome that was ultimately cured with surgical resection. In patients presenting with a history of psychiatric illness, it is important to consider the possibility of underlying, organic pathologies in the central nervous system affecting the relevant neuro-anatomical domains.

Neurosurgical treatment of anorexia nervosa: review of the literature from leucotomy to deep brain stimulation.

This paper reviews the literature on the surgical treatment of refractory anorexia nervosa (AN) and examines how this literature can inform current circuit models of the disease. The literature contains reports of 35 patients undergoing a neurosurgical procedure for the specific treatment of refractory AN, with the first reported operation, a lobotomy, in 1950. All patients were deemed treatment resistant according to contemporary standards, with the nature of the procedure changing with evolving surgical techniques and methods. All procedures targeted the limbic system and, in a majority of cases, were associated with reported symptomatic improvement. Neurosurgery in AN has been, and continues to be, reserved for patients with chronic and life-threatening illness, for whom conventional treatment has failed. Early procedures, which were viewed as life-saving measures, were crude by today's standards but targeted anatomic structures and pathways implicated in modern models of AN. The last decade has seen a concerted effort in elucidating the neurocircuitry underlying prominent etiologic and maintaining factors in AN, including mood, anxiety and dysfunctional reward processing. This has translated into the development of novel, focused therapeutic options for patients with treatment-refractory AN.

Treating the brain deep down: Brain surgery for anorexia nervosa?

Using brain surgery, specific areas in the brain can be stimulated with electrical impulses to reversibly change their activity and alleviate symptoms related to mental illnesses. This so-called deep brain stimulation and other methodological advances that even more selectively activate specific groups of neurons can give us clues as to what neural circuitry is involved in a particular mental disorder and whether therapeutic activation of these brain areas and neurons may be effective. In "Bedside to Bench", Eric Nestler discusses two trials of individuals with anorexia nervosa in which deep brain stimulation of different brain areas resulted in improvement of behavioral domains associated with the syndrome. The results and potential of this technique in animals and humans may bring us closer to understanding the neurobiology of anorexia nervosa, which still remains a mystery and poses a challenge for treatment. In "Bench to Bedside", Jennifer Warner-Schmidt peruses recent findings that uncover the functional connectivity of brain regions involved in depression and how activation of cortical regions can result in antidepressant effects that can compensate for the malfunction of other brain circuits that results in depression.

Deep-brain stimulation for anorexia nervosa.

OBJECTIVE: Anorexia nervosa (AN) is a complex and severe, sometimes life-threatening, psychiatric disorder with high relapse rates under standard treatment. After decades of brain-lesioning procedures offered as a last resort, deep-brain stimulation (DBS) has come under investigation in the last few years as a treatment option for severe and refractory AN. METHODS AND RESULTS: In this jointly written article, Sun et al. (the Shanghai group) report an average of 65% increase in body weight in four severe and refractory patients with AN after they underwent the DBS procedure (average follow-up: 38 months). All patients weighed greater than 85% of expected body weight and thus no longer met the diagnostic criteria of AN at last follow-up. Nuttin et al. (the Leuven group) describe other clinical studies that provide evidence for the use of DBS for AN and further discuss patient selection criteria, target selection, and adverse event of this evolving therapy. CONCLUSION: Preliminary results from the Shanghai group and other clinical centers showed that the use of DBS to treat AN may be a valuable option for weight restoration in otherwise-refractory and life-threatening cases. The nature of this procedure, however, remains investigational and should not be viewed as a standard clinical treatment option. Further scientific investigation is essential to warrant the long-term efficacy and safety of DBS for AN.

Successful anterior capsulotomy in comorbid anorexia nervosa and obsessive-compulsive disorder: case report.

BACKGROUND AND IMPORTANCE: State-of-the-art treatment of anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) often proves ineffective. Both disorders have common features, and anterior capsulotomy is a last-resort treatment for OCD. We document the effect of bilateral anterior capsulotomy in a patient with comorbid AN and OCD. CLINICAL PRESENTATION: A 38-year-old woman with life-threatening, chronic, treatment-refractory AN and OCD underwent anterior capsulotomy. Psychiatric and neuropsychological evaluations at baseline and at follow-up document the severity and progress of the case. Bilateral anterior capsulotomy resulted in normalization of eating pattern and weight and a significant decrease of food-related and overall obsessive-compulsive symptoms. Psychiatric evaluations and exposure to food cues confirmed the clinical improvement that was evident immediately after surgery and sustained at 3-month follow-up. CONCLUSION: This case report suggests that bilateral anterior capsulotomy can be a therapeutic option for patients with comorbid AN and OCD. However, a well-controlled study is warranted.

Eating disorder symptoms improved by antireflux surgery: a case report with a six-year follow up.

BACKGROUND: Anorexia nervosa (AN) is a chronic disorder that can overlap with lower esophageal sphincter failure and delayed gastric emptying. Patients with anorexia nervosa or other eating disorders may have a high incidence of gastrointestinal complaints, which can also be observed in gastroesophageal reflux disease (GERD). The overlap in the symptoms of these disorders may cause problems in differential diagnosis and treatment decisions. CASE DESCRIPTION: We report on a case of a patient with anorexia nervosa who did not benefit from conventional treatment strategies such as psychotropic drugs and psychotherapy, but remitted after antireflux surgery. CONCLUSION: When dealing with patients with symptoms of anorexia nervosa, physicians should keep in mind that these patients may have serious esophagogastric complications that can affect their response to psychiatric treatment. Alternatively, some patients with primary esophageal disorders may present with symptoms of eating disorders.

Electrical stimulation in the lateral hypothalamus in rats in the activity-based anorexia model.

OBJECT: One quarter of patients with anorexia nervosa have a poor outcome and continue to suffer chronically or die. Electrical brain stimulation may be of therapeutic benefit in some of these patients; however, the brain target for inducing symptom relief is unknown. In this study, the authors evaluated the effects of acute and chronic electrical stimulation in the lateral hypothalamus on food intake, locomotor activity, and survival time in rats in an activity-based anorexia model. METHODS: In an acute experiment, the authors electrically stimulated at 100 Hz and 0, 25, 50 and 75% of the maximal stimulation amplitude (that is, the amplitude leading to severe side effects) in the lateral hypothalamus on consecutive days during 4 test sessions in 10 rats and evaluated food intake and locomotor activity. In a chronic experiment, they compared food intake, wheel revolutions, and survival time between 6 rats that underwent electrical stimulation in the lateral hypothalamus (50% of maximal stimulation amplitude) and 8 rats that did not undergo stimulation. RESULTS: In the acute experiment, overall electrical stimulation (25, 50, and 75% combined) and stimulation at 75% of the maximal stimulation amplitude significantly decreased the locomotor activity. However, if the authors omitted results of 1 rat, in which the electrode tip was not located in the lateral hypothalamus on one side but rather in the supraoptic chiasm, the remaining results did not yield significance. No other differences were observed. CONCLUSIONS: When the findings of the current study are extrapolated to patients with anorexia nervosa, the authors do not expect major effects on symptoms with electrical stimulation at high frequency in the lateral hypothalamus.

[Legally effective consent with minors and incompetent patients]. / Rechtswirksame Einwilligung bei minderjährigen und willensunfähigen Patienten.

Legal consent to medical treatment requires comprehensive clarification and the patient's capability to consent. Minors under 14 years are usually not capable of consent -- the right to decide rests with the parents. With persons over 14 years the doctor must test for capability to consent. With adults incapable of consent the court-appointed guardian decides. In acute cases the doctor may act first and obtain permission afterwards. Contractual capability is decisive for a treatment contract to be effective and the doctor's claim for remuneration. Minors up to 7 years are absolutely contractually incapable. Since minors under 18 years are only limitedly contractually capable, the approval of the statutory guardian suffices. With contractually incapable adults the court-appointed guardian or in serious cases the Guardianship Court decides. The legal position is explained, using three sample cases.
