Patients with functional GI disorders (FGIDs) are commonplace in the gastroenterologist's practice. A number of these patients may be refractory to peripherally acting agents, yet respond to central neuromodulators. There are benefits and potential adverse effects to using TCAs, SSRIs, SNRIs, atypical antipsychotics, and miscellaneous central neuromodulators in these patients. These agents can benefit mood, pain, diarrhea, constipation, nausea, sleep, and depression. The mechanisms by which they work, the differences between classes and individual agents, and the various adverse effects are outlined...

Functional gastrointestinal disorders (FGIDs) are diagnosed and classified using the Rome criteria; the criteria may change over time as new scientific data emerge. The Rome IV was released in May 2016. The aim is to review the main changes in Rome IV. FGIDs are now called disorders of gut-brain interaction (DGBI). Rome IV has a multicultural rather than a Western-culture focus. There are new chapters including multicultural, age-gender-women's health, intestinal microenvironment, biopsychosocial, and centrally mediated disorders...

OBJECTIVE: To examine the relative contributions of disease activity and psychological factors to self-reported symptoms and disability in children with Crohn's disease. STUDY DESIGN: Participants (n = 127 children age 8-18 years) completed questionnaires on symptom severity and disability, as well as psychological measures assessing anxiety, depression, pain beliefs and coping. Disease activity was measured by the Pediatric Crohn's Disease Activity Index. Structural equation modeling was used to test the effects of disease activity and psychological factors on symptoms and disability...

Chronic abdominal pain has a widespread impact on the individual and the society. Identifying and explaining mechanisms of importance for the pain experience within a biopsychosocial context are central in order to select treatment that has a chance for symptom reduction. With current knowledge of brain-gut interactions, chronic abdominal pain, which mostly appears in functional gastrointestinal disorders, to a large extent involves pain mechanisms residing within the brain. As such, the use of centrally targeted pharmacotherapy as an effective treatment option is obvious in a selected number of patients...

BACKGROUND: Alterations in brain-gut communication and the intestinal microenvironment have been implicated in a variety of medical and neuropsychiatric diseases. Three central areas require basic and clinical research: (1) how the intestinal microenvironment interacts with the host immune system, central nervous system and enteric nervous system; (2) the role of the intestinal microenvironment in the pathogenesis of medical and neuropsychiatric disease; (3) the effects of diet, prebiotics, probiotics and fecal microbiota transplantation on the intestinal microenvironment and the treatment of disease...

Centrally Mediated Abdominal Pain Syndrome (CAPS), formerly known as Functional Abdominal Pain Syndrome, can be distinguished from other functional GI disorders by its strong central component and relative independence from motility disturbances. CAPS is a result of central sensitization with disinhibition of pain signals rather than increased peripheral afferent excitability. A newly described condition, Narcotic Bowel Syndrome (NBS)/Opioid-Induced GI Hyperalgesia, is characterized by the paradoxical development of or increases in abdominal pain associated with continuous or increasing dosages of opioids...

In this paper, we provide a general framework for understanding the functional gastrointestinal disorders (FGID) from a biopsychosocial perspective. More specifically, we provide an overview of the recent research on how the complex interactions of environmental, psychological, and biological factors contribute to the development and maintenance of the FGID. We emphasize that considering and addressing all these factors is a conditio sine qua non for appropriate treatment of these conditions. First, we provide an overview of what is currently known about how each of these factors - the environment, including the influence of those in an individual's family, the individual's own psychological states and traits, and the individual's (neuro)physiological make-up - interact to ultimately result in the generation of FGID symptoms...

Functional gastrointestinal disorders (FGIDs), the most common diagnoses in gastroenterology are recognized by morphological and physiological abnormalities that often occur in combination including motility disturbance, visceral hypersensitivity, altered mucosal and immune function, altered gut microbiota and altered central nervous system processing. Research on these gut-brain interaction disorders is based on using specific diagnostic criteria. The Rome Foundation has played a pivotal role in creating diagnostic criteria thus operationalizing the dissemination of new knowledge in the field of FGIDs...

Opioid-induced constipation (OIC) is a frequent symptom in patients treated with opioids and impacts the patients' quality of life. However, there is no generally accepted definition for OIC. The aims of this study were to identify definitions for OIC in clinical trials and Cochrane Reviews and to compile assessment tools and outcome measures that were used in clinical trials. In a systematic review, 5 databases (MEDLINE, PubMed, The Cochrane Library, Web of Science, and EMBASE) were searched to identify clinical trials assessing OIC in adult patients or healthy volunteers...

BACKGROUND In spite of the increasing trend in opioid abusers worldwide, the prevalence of narcotic bowel syndrome (NBS) is undetermined. We aimed to estimate the prevalence of NBS and other opioid bowel dysfunction (OBD) in opioid abusers in Kerman, southeast Iran. According to the best of our knowledge, this is the first study to assess the prevalence of NBS in opioid abusers. METHODS By referring to addiction treatment centers in Kerman city and in a cross-sectional study, 577 subjects with opium or opioid subtracts abuse were included in our study...

OBJECTIVES: The paradoxical development of chronic abdominal pain is an underrecognized side effect of opioid use. Narcotic bowel syndrome (NBS), occurring in a small proportion of chronic opioid users, consists of chronic or intermittent abdominal pain, which often increases in severity despite continued or escalating dosages of opioids prescribed to relieve pain. METHODS: A PubMed search was conducted using terms such as "narcotic bowel syndrome" and "opioid hyperalgesia" through January 2014...

Prescription opioid use for chronic non-cancer pain has reached epidemic levels in the USA. With this increased use is the recognition of serious opioid-related gastrointestinal complications such as narcotic bowel syndrome (NBS) and opioid-induced constipation (OIC). NBS consists of a paradoxical worsening of abdominal pain with escalating doses of opioids and is likely mediated by the central nervous system. Therapy requires an intensive multidisciplinary approach to detoxification. OIC is the most common gastrointestinal side effect of opioids...

IMPORTANCE: Abdominal pain after cholecystectomy is common and may be attributed to sphincter of Oddi dysfunction. Management often involves endoscopic retrograde cholangiopancreatography (ERCP) with manometry and sphincterotomy. OBJECTIVE: To determine whether endoscopic sphincterotomy reduces pain and whether sphincter manometric pressure is predictive of pain relief. DESIGN, SETTING, AND PATIENTS: Multicenter, sham-controlled, randomized trial involving 214 patients with pain after cholecystectomy without significant abnormalities on imaging or laboratory studies, and no prior sphincter treatment or pancreatitis randomly assigned (August 6, 2008-March 23, 2012) to undergo sphincterotomy or sham therapy at 7 referral medical centers...

Jacob E Kurlander, Douglas A Drossman
With increased prescription of opioids has come increased recognition of adverse consequences, including narcotic bowel syndrome (NBS). Characterized by incompletely controlled abdominal pain despite continued or increasing doses of opioids, NBS is estimated to occur in 4.2-6.4% of patients chronically taking opioids. Patients with NBS have a high degree of comorbid psychiatric illness, catastrophizing and disability; comorbid substance abuse must also be considered among this population. NBS should be distinguished from opioid-induced bowel disorder, which results from the effects of opioids on gastrointestinal motility and secretion...
