Chronic lower abdominal pain in an elderly female patient: a case report about sigmoid colon fistula and pelvic abdominal infection.

An elderly woman patient presented with a history of recurrent right lower abdominal pain accompanied by fever and abnormal vaginal discharge for 36 years worse for two weeks. Conservative medical treatment was ineffective, by laparoscopic exploration combined with intraoperative colonoscopy, the presence of a sigmoid colon fistula and pelvic abdominal infection with foreign bodies were confirmed. It was hypothesized that the occurrence of recurrent right lower abdominal pain and intestinal fistula may be potentially associated with tubal injection sterilization performed 36 years ago.

Percutaneous Electrical Nerve Field Stimulation in Children and Adolescents With Functional Dyspepsia-Integrating a Behavioral Intervention.

OBJECTIVES: Functional dyspepsia (FD) includes postprandial distress and epigastric pain syndrome. Percutaneous electrical nerve field stimulation (PENFS) in addition to behavioral interventions (BI) has shown benefits in children with functional abdominal pain but not specifically in FD. We aimed to assess the efficacy of PENFS for treating FD and compare the outcomes with those who received the combination of PENFS + BI. MATERIALS AND METHODS: Charts of patients with FD who completed four weeks of PENFS were evaluated. A subset of patients received concurrent BI. Demographic data, medical history, and symptoms were documented. Outcomes at different time points included subjective symptom responses and validated questionnaires collected clinically (Abdominal Pain Index [API], Nausea Severity Scale [NSS], Functional Disability Inventory [FDI], Pittsburgh Sleep Quality Index [PSQI], Children's Somatic Symptoms Inventory [CSSI], Patient-Reported Outcomes Measurement Information Systems [PROMIS] Pediatric Anxiety and Depression scales). RESULT: Of 84 patients, 61% received PENFS + BI, and 39% received PENFS alone. In the entire cohort, API (p < 0.0001), NSS (p = 0.001), FDI (p = 0.001), CSSI (p < 0.0001), PSQI (p = 0.01), PROMIS anxiety (p = 0.02), and depression (p = 0.01) scores improved from baseline to three weeks and at three months. Subjective responses showed nausea improvement (p = 0.01) and a trend for improvement in abdominal pain (p = 0.07) at week three. Abdominal pain subjectively improved at week three and three months (p = 0.003 and 0.02, respectively), nausea at week three and three months (p = 0.01 and 0.04, respectively), and a trend for improvement in sleep disturbances at week three and three months (p = 0.08 and p = 0.07, respectively) in the PENFS + BI group vs PENFS alone. CONCLUSION: Abdominal pain, nausea, functioning, somatization, sleep disturbances, anxiety, and depression improved at three weeks and three months after PENFS in pediatric FD. Subjective pain and nausea improvement were greater in the PENFS + BI group than in the group with PENFS alone, suggesting an additive effect of psychologic therapy.

Irritable bowel syndrome in children with chronic gastrointestinal symptoms in primary care.

BACKGROUND: Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder in children. However, in primary care, it is still unknown whether there are differences in the prognosis of children with IBS compared to other diagnostic subgroups. Therefore, our aim was to describe the course of symptoms and health-related quality of life (HRQoL) for children with chronic gastrointestinal symptoms who either do or do not fulfil the Rome criteria for IBS in primary care. Second, we compared the diagnosis of the general practitioner (GP) with the Rome criteria. METHODS: We conducted a prospective cohort study with 1-year follow-up, including children aged 4-18 years with chronic diarrhoea and/or chronic abdominal pain in primary care. During follow-up, the Rome III questionnaire, Child Health Questionnaire, and symptom questionnaires were completed. RESULTS: A total of 60/104 children (57.7%) fulfilled the Rome criteria for IBS at baseline. Compared to children without IBS, children with IBS were more commonly referred to secondary care, used more laxatives, and more often developed chronic diarrhoea and low physical HRQoL during 1 year. The diagnosis "IBS" from the GP matched the Rome criteria for only 10% of children, as most were diagnosed with "Constipation." CONCLUSIONS: There seems to be a difference in the treatment and prognosis of symptoms and HRQoL between children with and without IBS in primary care. This suggests that it is relevant to differentiate between these groups. The evaluation and use of feasible criteria to define IBS in different healthcare settings remains subject for further studies.

Interventional pathway in the management of refractory chronic flank pain: Prospective series in 45 patients.

BACKGROUND: Chronic flank pain can pose a therapeutic challenge. Current management centres on visceral pathology affecting the renal system. Acute exacerbations can be severe, requiring emergency admission. Patients usually have well-established visceral pathology including polycystic kidney disease, Fowler's syndrome, and renal calculi disease that often cause recurrent urinary tract infections. However, in many cases, despite negative investigations including imaging, biochemistry and urine analysis, flank pain persists. Abdominal myofascial pain syndrome is a poorly recognized pathology in this cohort. The report describes the underlying pathophysiology and a novel interventional management pathway for patients presenting with refractory flank pain secondary to abdominal myofascial pain syndrome. METHODS: Adult patients with refractory chronic flank pain at a tertiary renal unit were included as a part of an on-going prospective longitudinal audit. Patients refractory to standard management were offered the interventional pathway. The pathway included two interventions: quadratus lumborum block with steroid and pulsed radio frequency treatment. Patients completed brief pain inventory and hospital anxiety and depression scale questionnaires at baseline, 3 and 6 months postprocedure. Outcomes collected included ability to maintain employment, change in opioid consumption at 6 months and impact on emergency hospital admissions at 12 months after initiation of the pathway. RESULTS: Forty-five patients were referred to the pain medicine clinic over a seven-year period between 2014 and 2021. All patients were offered the interventions. Four patients refused due to needle phobia. Forty-one patients received transmuscular quadratus lumborum plane block with steroids. Twenty-seven patients (27/41, 66%) reported durable benefit at 6 months and six patients (6/41, 15%) had clinically significant relief at 3 months. Fifteen patients received pulsed radiofrequency to quadratus lumborum plane and 11 patients (73%) reported > 50% analgesia at 6 months. Treatment failure rate was 10% (4/41). Opioid consumption at 6 months and emergency admission at 12 months were reduced post intervention. CONCLUSION: Abdominal myofascial pain syndrome is a poorly recognized cause of chronic flank pain syndrome. The interventional management pathway could be an effective solution in this cohort.

Effects of Spinal Cord Stimulation in Patients with Chronic Nausea, Vomiting, and Refractory Abdominal Pain.

BACKGROUND: Patients with chronic nausea and vomiting often also have chronic abdominal pain. Spinal cord stimulation (SCS) may provide pain control, but scarce data are available regarding the effect of SCS on chronic nausea and vomiting. AIMS: We aimed to determine the effect of SCS in patients with chronic nausea, vomiting, and refractory abdominal pain. METHODS: Retrospective chart review of 26 consecutive patients who underwent SCS trial for a primary diagnosis of nausea, vomiting and refractory abdominal pain. RESULTS: 26 patients underwent SCS trial, with an average age of 48 years. Twenty-three patients (88.5%) reported > 50% pain relief during the temporary SCS trial and then underwent permanent implantation. Patients were then followed for 41 (22-62) months. At baseline, 20 of the 23 patients (87.0%) reported daily nausea, but at 6 months and the most recent follow-up, only 8 (34.8%) and 7 (30.4%) patients, respectively, had daily nausea (p < 0.001). Days of nausea decreased from 26.3 days/month at baseline to 12.8 and 11.7 days/month at 6 months and at the most recent visit, respectively. Vomiting episodes decreased by 50%. Abdominal pain scores improved from 8.7 to 3.0 and 3.2 at 6 months and the most recent visit, respectively (both p < 0.001). Opioid use decreased from 57.7 mg MSO4 equivalents to 24.3 mg at 6 months and to 28.0 mg at the latest patient visit (both p < 0.05). CONCLUSIONS: SCS may be an effective therapy for long-term treatment of symptoms for those patients afflicted with chronic nausea, vomiting, and refractory abdominal pain.

A therapeutic guide on pediatric irritable bowel syndrome and functional abdominal pain-not otherwise specified.

Disorders of the gut-brain interaction negatively impact quality of life and carry a substantial socioeconomic burden. Irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP-NOS) are common functional abdominal pain disorders in childhood. The pathophysiology is not fully understood, and high-quality intervention trials and international guidelines are missing. Therefore, the management of these disorders remains challenging. This review aims to provide an up-to-date overview of therapeutic possibilities for pediatric IBS or FAP-NOS and recommends management strategies. To prevent unnecessary referrals and extensive costs, it is fundamental to make a positive diagnosis of IBS or FAP-NOS in children with chronic abdominal pain with only minimal investigations. A tailor-made approach for each patient, based on the accompanying physical and psychological symptoms, is proposed to date. CONCLUSION: Shared decision-making including non-pharmacological and pharmacological interventions should be considered and discussed with the family. WHAT IS KNOWN: • Irritable bowel syndrome and functional abdominal pain-not otherwise specified are common in childhood. • Although the number of treatment options has grown recently, managing these disorders can be challenging and unsatisfactory, and no evidence-based international management guidelines are available. WHAT IS NEW: • We suggest using a stepwise individualized approach to management, where after first-line management, both non-pharmacological and pharmacological interventions should be discussed.

Analgesia in patients with adhesion-related chronic abdominal and pelvic pain after surgery: a systematic review.

BACKGROUND AND OBJECTIVE: Adhesions are the most common cause of chronic abdominal pain after surgery. Surgical adhesiolysis can relieve symptoms in selected patients, but many require other treatments. The aim of this study is to evaluate analgesic treatments other than abdominal surgery in chronic pain related to adhesions. DATABASE AND DATA TREATMENT: A search was conducted in PubMed, Embase, and Central. Studies with patients suffering from chronic postoperative pain related to adhesions and undergoing all types' analgesic treatment were included. The primary outcome was the number of patients who improved in pain at long-term follow-up (at least 1 year). Secondary outcomes included improvement in pain at 3 months follow-up, quality of life, and physical functioning. RESULTS: Searches identified 3022 citations. Four studies were included, one trial, one cohort study, and two case reports. The primary outcome was not reported. In a small trial (n = 18) pregabalin tended to have a benefit over placebo improving pain at 3 months. In the cohort study, 17 patients with chronic pelvic pain underwent a trial of sacral nerve stimulation. Eight patients who responded positively received an implanted device for continuous modulation, reporting sustainable improvement during follow-up (range: 6-36 months). One case report described improved pain at 6 months with trans-abdominis plane stimulation. The second report described improvement of physical function with manual therapy at long-term follow-up. CONCLUSIONS: Low level of evidence is available regarding analgesic treatments of chronic abdominal and pelvic pain related to adhesions. The benefit of pregabalin is doubtful; nerve modulation is promising in a selected group.HighlightsAdhesions are a frequent cause of chronic abdominal and pelvic pain after surgery.Many patients are not good candidates for surgery (Adhesiolysis) or have relapses of pain.There is an important knowledge gap regarding non-surgical analgesic treatment.Analgesia in adhesion-related chronic abdominal pain after surgery.

[Application of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain]. / è¶ å£°å¼•å¯¼å† é•œä¸‹é€†è¡Œé˜‘å°¾ç‚Žæ²»ç–—æœ¯åœ¨é˜‘å°¾ç›¸å ³æ ¢æ€§è ¹ç—›æ‚£å„¿ä¸­çš„åº”ç”¨ä»·å€¼.

OBJECTIVES: To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain. METHODS: A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate. RESULTS: Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×109/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%). CONCLUSIONS: Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

Chronic Abdominal Pain in General Practice.

Background and Summary: Chronic abdominal pain is a challenging complaint for both primary care providers and gastroenterologists alike, due to a broad differential diagnosis and sometimes extensive and negative workup. In the absence of red flag features that herald more acute conditions, the majority of patients with chronic abdominal pain have a benign cause or a functional disorder (e.g., irritable bowel syndrome). The costs associated with a diagnostic workup are an expensive burden to health care. A systematic approach for evaluating patients and initiating a management plan are recommended in the primary care setting. Undiagnosed abdominal pain should be investigated starting with a detailed history and physical examination. Diagnostic investigations should be limited and adapted according to the clinical features, the alarm symptoms, and the symptom severity. This review will focus on the diagnostic tools which general practitioners utilize in the evaluation of chronic abdominal pain. Key Messages: The primary role of the general practitioner is to differentiate an organic disease from a functional one, to refer to a specialist, or to provide treatment for the underlying cause of pain. The functional disorders should be considered after the organic pathology has been confidently excluded. Once a diagnosis of functional pain is established, repetitive testing is not recommended and the patient should be referred to receive psychological support (e.g., cognitive therapy) associated with available pharmacological therapeutic options.

Clinico-pathologic findings in patients with median arcuate ligament syndrome (celiac artery compression syndrome).

Median Arcuate Ligament Syndrome (MALS) is a rare entity characterized by severe post-prandial epigastric pain, nausea, vomiting, and/or weight loss. Symptoms have been attributed to vascular compression (celiac artery compression syndrome, CACS), but it remains controversial whether they could be secondary to neural compression. Literature review identified rare description of pathologic findings in surgery journals. The clinico-pathologic findings of four MALS patients who underwent robotic or laparoscopic surgery in our hospital are described. All our patients were female with a median age of 32.5 (range 25-55 years), and a median BMI of 23.5 kg/m2. They presented with chronic often post-prandial abdominal pain (4/4), nausea (3/4), emesis (2/4), anorexia (1/4), and weight loss (1/4). Two patients had a history of Crohn's disease. At intraoperative exploration, the celiac artery and adjacent nerves and ganglia were encased and partially compressed by fibrotic tissue in each patient. In each case laparoscopic excision of fibrotic tissue, celiac plexus and ligament division and was performed; celiac plexus nerve block was also performed in one patient. After surgical intervention, symptoms improved in three of the patients whose specimens show periganglionic and perineural fibrosis with proliferation of small nerve fibers. Our findings support neurogenic compression as a contributing factor in the development of pain and other MALS symptoms, and favor the use of MALS rather than CACS as diagnostic terminology. To further study the pathogenesis of this unusual syndrome, surgeons should submit all tissues excised during MALS procedures for histopathologic examination.

Dyspepsia in children: organic or functional? Experience in a tertiary care hospital.

INTRODUCTION: Dyspepsia comprises a group of symptoms that can have organic or functional origin. The purpose of this study was to describe the main causes of dyspepsia and its clinical evolution in children cared for in a tertiary care hospital. MATERIAL AND METHODS: Retrospective study in children with dyspepsia. Patients underwent endoscopy with biopsy and rapid urease test to detect the presence of Helicobacter pylori. In case of normal endoscopy and biopsy, hydrogen breath test was performed. In all cases, follow-up was provided in order to evaluate symptom improvement. RESULTS: One hundred children were included, out of whom 52 were girls; mean age was 8.59 years. Esophagitis or erosive gastropathy were found in 54% of the cases (n = 54), H. pylori infection in 12% (n = 12), small intestinal bacterial overgrowth in 12% (n = 12), and functional dyspepsia in 20% (n = 20). CONCLUSION: In children with dyspepsia, organic causes should first be ruled out before dyspepsia being characterized as functional. In general terms, we consider that a stepped approach that includes endoscopy with biopsy, search for H. pylori and hydrogen breath test is necessary.

INTRODUCCIÓN: La dispepsia consiste en un conjunto de síntomas que pueden tener origen orgánico o funcional. El objetivo de este estudio fue describir las principales causas de la dispepsia y su evolución clínica en niños en un hospital de tercer nivel. MATERIAL Y MÉTODOS: Estudio retrospectivo en niños con dispepsia. Los pacientes fueron sometidos a endoscopia con toma de biopsia y prueba de urea rápida para Helicobacter pylori. En caso de endoscopia y biopsia normal, se tomó prueba de hidrogeniones en aliento. En todos los casos se dio seguimiento para evaluar la mejoría de síntomas. RESULTADOS: Se incluyeron 100 niños, de los cuales 52 eran niñas; la edad media fue de 8.59 años. Se encontró esofagitis y gastropatía erosiva en el 54% de los casos (n = 54), infección por H. pylori en el 12% (n = 12), sobrecrecimiento bacteriano del intestino delgado en el 12% (n = 12) y dispepsia funcional en el 20% (n = 20). CONCLUSIÓN: En niños con dispepsia se deben de descartar primero causas orgánicas antes de diagnosticar dispepsia funcional. En términos generales consideramos que es necesario un abordaje escalonado que incluya endoscopia con toma de biopsia, búsqueda de H. pylori y una prueba de hidrogeniones.

Laparoscopy as a Diagnostic and Therapeutic Modality for Chronic Abdominal Pain of Unknown Etiology: A Literature Review.

BACKGROUND: Investigate the diagnostic and therapeutic utility of laparoscopy in the management of patients with chronic abdominal pain of unknown origin. METHODS: Ovid MEDLINE, PubMed, and SCOPUS databases were queried to identify relevant published studies. Data on the diagnostic and therapeutic utility of laparoscopy were abstracted and summarized. RESULTS: Laparoscopy achieved a diagnosis in 65% to 94% of patients with chronic abdominal pain of unknown origin. Common intraoperative findings included adhesions, chronic appendicitis, hernias, and enlarged mesenteric lymph nodes. These findings corresponded with the therapeutic procedures that were performed, including laparoscopic adhesiolysis, appendectomy, and hernia repair. Therapeutic utility of laparoscopy based on pain relief, patient satisfaction, and quality of life ranged from 63% to 94%. CONCLUSIONS: Based on current available evidence, diagnostic laparoscopy (DL) is a safe and effective method for identifying organic causes of chronic abdominal pain. Laparoscopic treatment also resulted in substantial pain relief for a majority of patients. However, the efficacy of laparoscopic adhesiolysis remains controversial. We would recommend the use of DL as an early diagnostic tool, but more robust studies are needed to establish the breadth of its therapeutic utility in clinical practice.

Ultrasound-Guided Subcostal TAP Block with Depot Steroids in the Management of Chronic Abdominal Pain Secondary to Chronic Pancreatitis: A Three-Year Prospective Audit in 54 Patients.

BACKGROUND: Chronic pancreatitis is a common cause of recurrent chronic abdominal pain that utilizes significant health care resources. Pain in chronic pancreatitis can be of two types. Visceral pain occurs during ongoing pancreatic inflammation. Once pancreatic inflammation subsides, the pain generator can move to the abdominal wall as a result of viscerosomatic convergence and present as abdominal myofascial pain syndrome. Subcostal transversus abdominis plane block is an abdominal plane block that has been proven effective in upper abdominal pain of somatic origin. DESIGN: The authors discuss the two distinct types of chronic abdominal pain as a result of pancreatitis and present a prospective audit of a management pathway. METHODS: Over a three-year period, 54 patients with chronic abdominal pain as a result of pancreatitis were prospectively audited at a tertiary care university hospital. Patients were offered bilateral subcostal transversus abdominis plane block with depot steroids as the primary interventional treatment in the pathway. RESULTS: In patients with myofascial pain secondary to chronic pancreatitis, the block was effective in producing clinically significant pain relief at three months (95%, 20/21) and durable pain relief lasting six months (62%, 13/21). In patients with visceral pain, the block produced a transient benefit lasting two to three weeks in one-third (six of 17). CONCLUSIONS: Subcostal transversus abdominis plane block may be an option in the management of abdominal myofascial pain syndrome secondary to chronic pancreatitis. The block is ineffective in producing clinically significant pain relief in the presence of ongoing pancreatic inflammation.

Diagnostic Potential of Magnetic Resonance Imaging in Chronic Abdominal Pain.

INTRODUCTION: About half of the adult patients suffering from chronic abdominal pain may have no organ-related cause. Our purpose was to evaluate the additional information of magnetic resonance imaging (MRI) in diagnosing the underlying organic causes of such pain. METHODS: We performed retrospective audit of 636 consecutive abdominal MRI in patients suffering from nonspecific abdominal pain (NSAP) during years 2014-2017. Medical history, clinical examination, endoscopy reports, and the results of MRI were compared in all patients. The hypothesis was that MRI increases markedly the diagnostic specificity of patients' symptoms. RESULTS: The mean age of patients was 66 ± 14 years and 60 percent were females. Duration of abdominal pain ranged from 1 month to 30 years (median 1.1 ± 4.0 years). Concurrently with abdominal MRI (n = 636), also ultrasound (n = 106, 17%), colonoscopy (n = 222, 35%), and gastroscopy (n = 217, 34%) were performed. Abdominal MRI revealed additional information in 161/636 (25%) of NSAP patients. Spinal and pelvic bone abnormalities (n = 107) and malignant tumors (n= 31) were the most significant organ-specific findings changing the treatment algorithm. CONCLUSIONS: When computerized tomography is not available in outpatient clinics, abdominal MRI increases markedly diagnostic specificity and alters the treatment in 1 of 4 patients suffering from NSAP. Abdominal MRI is therefore suggested for patients suffering from severe symptoms of NSAP.

A Comprehensive Review of the Celiac Plexus Block for the Management of Chronic Abdominal Pain.

PURPOSE OF REVIEW: Chronic abdominal pain (CAP) is a significant health problem that can dramatically affect quality of life and survival. Pancreatic cancer is recognized as one of the most painful malignancies with 70-80% suffering from substantial pain, often unresponsive to typical medical management. Celiac plexus neurolysis and celiac plexus block (CPB) can be performed to mitigate pain through direct destruction or blockade of visceral afferent nerves. The objective of this manuscript is to provide a comprehensive review of the CPB as it pertains to CAP with a focus on the associated anatomy, indications, techniques, neurolysis/blocking agents, and complications observed in patients who undergo CPB for the treatment of CAP. RECENT FINDINGS: The CAP is difficult to manage due to lack of precision in diagnosis and limited evidence from available treatments. CAP can arise from both benign and malignant causes. Treatment options include pharmacologic, interventional, and biopsychosocial treatments. Opioid therapy is typically utilized for the treatment of CAP; however, opioid therapy is associated with multiple complications. CPB has successfully been used to treat a variety of conditions resulting in CAP. The majority of the literature specifically related to CPB is surrounding chronic pain associated with pancreatic cancer. The literature shows emerging evidence in managing CAP with CPB, specifically in pancreatic cancer. This review provides multiple aspects of CAP and CPB, including anatomy, medical necessity, indications, technical considerations, available evidence, and finally complications related to the management.

Neuromodulators for Functional Gastrointestinal Disorders (Disorders of Gut-Brain Interaction): A Rome Foundation Working Team Report.

BACKGROUND & AIMS: Central neuromodulators (antidepressants, antipsychotics, and other central nervous system-targeted medications) are increasingly used for treatment of functional gastrointestinal disorders (FGIDs), now recognized as disorders of gut-brain interaction. However, the available evidence and guidance for the use of central neuromodulators in these conditions is scanty and incomplete. In this Rome Foundation Working Team report, a multidisciplinary team summarized available research evidence and clinical experience to provide guidance and treatment recommendations. METHODS: The working team summarized the literature on the pharmacology of central neuromodulators and their effects on gastrointestinal sensorimotor function and conducted an evidence-based review on their use for treating FGID syndromes. Because of the paucity of data for FGIDs, we included data for non-gastrointestinal painful disorders and specific symptoms of pain, nausea, and vomiting. This information was combined into a final document comprising a synthesis of available evidence and recommendations for clinical use guided by the research and clinical experience of the experts on the committee. RESULTS: The evidence-based review on neuromodulators in FGID, restricted by the limited available controlled trials, was integrated with open-label studies and case series, along with the experience of experts to create recommendations using a consensus (Delphi) approach. Due to the diversity of conditions and complexity of treatment options, specific recommendations were generated for different FGIDs. However, some general recommendations include: (1) low to modest dosages of tricyclic antidepressants provide the most convincing evidence of benefit for treating chronic gastrointestinal pain and painful FGIDs and serotonin noradrenergic reuptake inhibitors can also be recommended, though further studies are needed; (2) augmentation, that is, adding a second treatment (adding quetiapine, aripiprazole, buspirone α2δ ligand agents) is recommended when a single medication is unsuccessful or produces side effects at higher dosages; (3) treatment should be continued for 6-12 months to potentially prevent relapse; and (4) implementation of successful treatment requires effective communication skills to improve patient acceptance and adherence, and to optimize the patient-provider relationship. CONCLUSIONS: Based on systematic and selectively focused review and the consensus of a multidisciplinary panel, we have provided summary information and guidelines for the use of central neuromodulators in the treatment of chronic gastrointestinal symptoms and FGIDs. Further studies are needed to confirm and refine these recommendations.

Focus on current and future management possibilities in inflammatory bowel disease-related chronic pain.

INTRODUCTION: Visceral pain is a symptom reported by over 70% of inflammatory bowel disease (IBD) sufferers. So far, a single, specific cause of this debilitating state has not been established. Chronic pain is one of the most important factors decreasing the quality of life in IBD course. Concurrently, management of pain is the most challenging issue encountered by clinicians in IBD treatment. AREAS COVERED: This review focuses on pathophysiology of inflammatory bowel disease-caused visceral pain and explores currently available approaches to its management. We also covered recent pharmacological developments in the field. CONCLUSIONS: Pain-related disability has major effects on quality of life and on functional and social outcomes in IBD patients. Currently, there is no one standardized method of managing chronic visceral pain in IBD. Therefore, future development, focusing primarily on alleviating the pain, but also on reducing inflammation, is essential.

Fructose malabsorption in asymptomatic children and in patients with functional chronic abdominal pain: a prospective comparative study.

The objective of this prospective cohort study was to compare fructose malabsorption in patients with functional chronic abdominal pain and in healthy children. The sample was divided into two groups: asymptomatic children and pain-predominant functional gastrointestinal disorders according to the Rome IV criteria. All children were tested for fructose malabsorption by a standardized breath hydrogen test. Hydrogen and methane were measured and the test was presumed positive when it exceeded 20 ppm above baseline. If positive, patients were given a low-fructose diet and the response was evaluated. One hundred five children were included (34 healthy children, 71 with functional chronic abdominal pain), with similar demographic characteristics in both groups (35.2% male, age 9.5 ± 2.8 years). Hydrogen levels in breath were tested through a hydrogen test for fructose demonstrating malabsorption in 58.8% of healthy children (95%CI 40.8%-76.8%) and in 40.8% of children with chronic abdominal pain (95%CI 28.7%-53.0%), removing those who had bacterial overgrowth. Twenty-one of 31 patients with symptoms and a positive test (72.4%) reported an improvement on a low-fructose diet.Conclusion: Fructose malabsorption is more common in asymptomatic children than in patients with chronic abdominal pain. Better standardized test conditions are necessary to improve accuracy of diagnosis before using this test in clinical practice. What is Known: • Although fructose malabsorption is believed to be related with chronic abdominal pain, high-quality evidence is lacking. • Concerns have raised regarding the use of breath hydrogen test for fructose malabsorption in children with chronic abdominal pain. What is New: • Fructose malabsorption is not more common in children with pain-predominant functional gastrointestinal disorders than in asymptomatic children. • Improvement in symptoms with low-fructose diet may indicate that, although patients with pain-predominant functional gastrointestinal disorders did not have a higher percentage of malabsorption, they had greater fructose intolerance.

Severity of Diverticulitis Does Not Influence Abdominal Complaints during Long-Term Follow-Up.

BACKGROUND: Diverticulitis can lead to localized or generalized peritonitis and consequently induce abdominal adhesion formation. If adhesions would lead to abdominal complaints, it might be expected that these would be more prominent after operation for perforated diverticulitis with peritonitis than after elective sigmoid resection. AIMS: The primary outcome of the study was the incidence of abdominal complaints in the long-term after acute and elective surgery for diverticulitis. METHODS: During the period 2003 through 2009, 269 patients were operated for diverticular disease. Two hundred eight of them were invited to fill out a questionnaire composed of the gastrointestinal quality of life index and additional questions and finally 109 were suitable for analysis with a mean follow-up of 7.5 years. RESULTS: Analysis did not reveal any significant differences in the incidence of abdominal complaints or other parameters. CONCLUSION: This retrospective study on patients after operation for diverticulitis shows that in the long term, the severity of the abdominal complaints is influenced neither by the stage of the disease nor by the fact of whether it was performed in an acute or elective setting.
