Percutaneous electrical nerve field stimulation for adolescents with irritable bowel syndrome: Cost-benefit and cost-minimization analysis.

Abdominal pain drives significant cost for adolescents with irritable bowel syndrome (IBS). We performed an economic analysis to estimate cost-savings for patients' families and healthcare insurance, and health outcomes, based on abdominal pain improvement with percutaneous electrical nerve field stimulation (PENFS) with IB-Stim® (Neuraxis). We constructed a Markov model with a 1-year time horizon comparing outcomes and costs with PENFS versus usual care without PENFS. Clinical outcomes were derived from a sham-controlled double-blind trial of PENFS for adolescents with IBS. Costs/work-productivity impact for parents were derived from appropriate observational cohorts. PENFS was associated with 18 added healthy days over 1 year of follow-up, increased annual parental wages of $5,802 due to fewer missed work days to care for the child, and $4744 in cost-savings to insurance. Percutaneous electrical field nerve stimulation for adolescents with IBS appears to yield significant cost-savings to patients' families and insurance.

Electroacupuncture for abdominal pain relief in patients with acute pancreatitis: A three-arm randomized controlled trial.

BACKGROUND: Electroacupuncture (EA) may reduce the severity of acute pancreatitis (AP) and provide additional pain relief in patients with chronic pancreatitis. However, the ability of EA to relieve pain in patients with AP has not been well documented. OBJECTIVE: This study was undertaken to compare the pain-relieving effects of EA and conventional treatment in patients with AP. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This study was conducted using a randomized, controlled, three-arm, parallel-group and multi-center design. Patients diagnosed with AP were randomly and equally assigned to EA1, EA2 or control groups. All participants received conventional standard-of-care therapy for AP. Local EA alone was administered in EA1, and local plus distal EA was given in EA2. Local EA included two abdominal acupoints, while distal EA included twelve peripheral acupoints. EA groups underwent one session of EA daily for 4 days (days 1-4), or until pain was resolved or discharged. MAIN OUTCOME MEASURES: The primary outcome measure was the change in the visual analogue scale (VAS; 0-100) pain score between baseline and day 5. RESULTS: Eighty-nine participants were randomized into EA1, EA2 and control groups, and 88 (EA1, 30; EA2, 29; control, 29) were included in the full-analysis set. VAS score change (median [interquartile range]) on day 5 was (12.3 ± 22.5) in the EA1 group, (10.3 ± 21.5) in the EA2 group, and (8.9 ± 15.2) in the control group. There were not significant differences in the change in VAS score among treatments (P = 0.983). However, time to food intake was significantly shorter in the EA group (EA1 + EA2) than in the control group (median 2.0 days vs 3.0 days), with a hazard ratio of 0.581 (P = 0.022; 95% CI, 0.366-0.924). No significant adverse events occurred. CONCLUSION: EA treatment did not significantly reduce pain after 4 days of treatment in patients with AP-associated abdominal pain but significantly reduced time to first food intake.

[Holistic treatment of endometriosis]. / Ganzheitliche Behandlung der Endometriose.

BACKGROUND: The pain phenomena caused by endometriosis are manifold. In addition to nociceptive pain there is also a nociplastic reaction with central sensitization. Atypical symptoms, such as acyclic lower abdominal pain, radiating pain, nonspecific bladder and intestinal complaints or even depression increasingly occur in addition to the classical cyclic complaints, such as severe dysmenorrhea, cyclic lower abdominal pain, dyspareunia, dysuria and dyschezia. Due to the diffuse range of symptoms, affected patients often consult not just gynecologists but also specialists from other disciplines (internal medicine, gastroenterology, orthopedics, pain therapy, psychology etc.). OBJECTIVE: The complexity of endometriosis is presented. The resulting approaches to multimodal interdisciplinary holistic treatment are described. RESULTS: Interdisciplinary concepts should be involved in the optimal treatment of endometriosis patients along with hormonal and surgical treatment, mostly under the supervision of a gynecologist and pain management, dietary changes, psychological support and physiotherapeutic management should also be included. This article provides an overview of possible treatment strategies for chronic symptomatic endometriosis. CONCLUSION: Based on multimodal treatment strategies and regarding the complex pathophysiological alterations of this disease, the complex complaints that significantly impair the quality of life of endometriosis patients can be greatly improved.

Stercoral Colitis in the Emergency Department: A Retrospective Review of Presentation, Management, and Outcomes.

STUDY OBJECTIVE: Stercoral colitis is inflammation of the bowel wall caused by fecal impaction. Despite reported high morbidity and risk of perforation, little research assessing outcomes is available. This study characterizes the presentation, management, and outcomes of emergency department patients with stercoral colitis. METHODS: We performed a retrospective chart review of ED patients with stercoral colitis identified on computed tomography (CT) scan. Of 814, 522 visits to multiple EDs across the US, 269 met the inclusion criteria. Variables regarding patient presentation, management, and outcomes were extracted from electronic medical records. Results were analyzed with percentages and 95% confidence intervals (CIs). RESULTS: Of 269 patients, the median age was 76 years. The most common chief concern was abdominal pain/distension (33.8%). However, abdominal pain was documented as absent in 62.1% of cases. The most common CT findings included fecal impaction (96.7%), bowel wall inflammation (72.9%), and fat stranding (48.3%). Eighty-four (31.2%) patients were discharged home from the ED, and over half of these (45/84, 53.6%) received no enema, laxatives, or disimpaction. Overall, 9 patients (3.3%, 95% CI 1.6% to 6.5%) required surgical management of a related complication within 3 months, 27 (10.0%, 95% CI 6.8% to 14.4%) returned to the ED within 72 hours, and 9 (3.3%, 95% CI 1.6% to 6.5%) died from a cause related to stercoral colitis within 3 months. CONCLUSION: Patients with stercoral colitis often present in a nonspecific manner, and short-term mortality is substantial. In this study, most discharged patients did not receive recommended treatment. This represents the largest ED study of stercoral colitis and provides further evidence linking this diagnosis with adverse outcomes.

Non-pharmacological strategies to treat irritable bowel syndrome: 2022 update.

Irritable bowel syndrome (IBS) is a chronic functional disorder characterized by abdominal pain associated with changes in stool frequency or form, in absence of organic disease. The treatment of IBS is often challenging and should be individually adjusted according to the prevalent symptomatology. Pharmacological treatment for IBS with diarrhea includes peripheral opioid agonists, bile acid sequestrants and antibiotics, while IBS with constipation can be treated with soluble fibers, osmotic agents or prokinetics. In case of abdominal pain, the available pharmacological options are antispasmodics, peripheral opioid agonists or antidepressants. Along with pharmacotherapy, non-pharmacological interventions should be considered as they can play an important role in symptom control. The first-line approach includes lifestyle modifications and dietary advice. Microbiota manipulation through probiotics, prebiotics and symbiotics is a widely used strategy, although the evidence upon the most effective among these in specific IBS subtypes is still unclear. Fecal microbiota transplantation is still in experimental phase for IBS, but it is giving promising results. Psychological therapies may be effective in patients with IBS, despite their application can be limited by long duration, high costs and poor patient's acceptance. Alternative medicine approaches, such as acupuncture, body relaxation techniques, dietary supplements or Chinese herbs, have been proposed; however, the evidence upon their efficacy and safety is still controversial.

[Efficacy of newly developed kombucha-based specialized food product for treatment of constipation-predominant irritable bowel syndrome].

According to studies, the prevalence of constipation in the population can reach 27% due to the low intake of dietary fiber. Increasing dietary fiber intake can improve bowel movements. The aim of the study was to assess the efficacy of a non-alcoholic fermented pasteurized kombucha drink enriched with inulin and vitamins in patients with constipation-predominant irritable bowel syndrome (IBS). Material and methods. The study (NCT05164861) was approved by Local Ethics Committee and enrolled subjects with IBS (according to ROME IV). The subjects were randomized to receive either 220 ml of a non-alcoholic drink, based on pasteurized kombucha (KG), enriched with inulin (1.15 g/100 ml) or 220 ml water (control group, CG), for 10 days. Standard examination included evaluation of stool frequency (bowel movements per day), stool form (with the Bristol stool scale) and evaluation of concomitant symptoms (abdominal pain/discomfort, abdominal fullness, bloating, and feeling of incomplete bowel emptying) with the use of 5-point Likert scale before (BL) and 10 days after the start of intervention (EOT). Using visual analog scales (VAS), the palatability of the studied food was assessed at the beginning and end of the observation period. Results. Significant increase of stool frequency was found at the EOT compared to BL in KG (n=20), Mean±SD: 0.60±0.31 to 0.85±0.19 times/day; p=0.004, while there was no change in CG (n=20): 0.63±0.33 vs 0.72±0.28, p=0.6. Mean values of stool scale form increased in KG (3.0±1.2 to 4.4±1.0, p=0.001), while remained unchanged in CG (2.9±1.2 vs 3.4±1.2, p=0.6). Mean values of the Bristol stool scale in KG and CG differed significantly at EOT (p=0.018). Significant decrease in mean values of incomplete bowel emptying feeling was found in KG (1.88±0.78 at BL vs 1.41±0.56 points at EOT, p=0.015), but not in the control group. There were no statistically significant differences between patient's reports of the studied groups for other symptoms (bitterness and dryness in the mouth, heartburn, nausea, abdominal pain and heaviness in the stomach after eating). Conclusion. The effectiveness of a pasteurized fermented non-alcoholic drink based on kombucha enriched with inulin has been proven by reducing the intensity of complaints significant for constipation, normalizing the frequency and consistency of stools.

The effect of 'Zesy002' kiwifruit (Actinidia chinensis var. chinensis) on gut health function: a randomised cross-over clinical trial.

Functional gastrointestinal disorders including constipation affect up to 14 % of the world's population. Treatment is difficult and challenging resulting in a need for alternative safe and effective therapies. The present study investigated whether daily consumption of three gold-fleshed kiwifruit could alleviate constipation and improve gastrointestinal discomfort in mildly constipated individuals with and without pain. A total of thirty-two participants were enrolled in a 16-week randomised, single-blind, crossover study. Participants received either three 'Zesy002' kiwifruit or 14·75 g Metamucil® (5 g dietary fibre/d (a positive control)) for 4 weeks each with a 4-week washout between treatments. A 2-week washout period was included at the beginning and end of the study. Daily bowel habit diaries were kept throughout the study. The primary outcome measure was differences in the number of complete spontaneous bowel movements (CSBM). Secondary outcome measures were bowel movement frequency and stool form as well as digestive symptoms and comfort. The number of CSBM per week was significantly greater during daily consumption of three kiwifruit compared with the baseline (6·3 v. 3·3; P < 0·05) and the Metamucil® treatment (6·3 v. 4·5; P < 0·05). Stool consistency was also improved, with kiwifruit producing softer stools and less straining (P < 0·05). Gastrointestinal discomfort was also improved compared with baseline for abdominal pain, constipation and indigestion (P < 0·05) during the kiwifruit intervention and constipation during the Metamucil® intervention (P < 0·05). This randomised controlled trial demonstrates that daily consumption of three gold-fleshed kiwifruit is associated with a significant increase of two CSBM per week and reduction in gastrointestinal discomfort in mildly constipated adults.

Neurostimulation for abdominal pain-related functional gastrointestinal disorders in adolescents: a randomised, double-blind, sham-controlled trial.

BACKGROUND: Development of safe and effective therapies for paediatric abdominal pain-related functional gastrointestinal disorders is needed. A non-invasive, US Food and Drug Administration-cleared device (Neuro-Stim, Innovative Health Solutions, IN, USA) delivers percutaneous electrical nerve field stimulation (PENFS) in the external ear to modulate central pain pathways. In this study, we evaluated the efficacy of PENFS in adolescents with abdominal pain-related functional gastrointestinal disorders. METHODS: In this randomised, sham-controlled trial, we enrolled adolescents (aged 11-18 years) who met Rome III criteria for abdominal pain-related functional gastrointestinal disorders from a single US outpatient gastroenterology clinic. Patients were randomly assigned (1:1) with a computer-generated randomisation scheme to active treatment or sham (no electrical charge) for 4 weeks. Patients were stratified by sex and presence or absence of nausea. Allocation was concealed from participants, caregivers, and the research team. The primary efficacy endpoint was change in abdominal pain scores. We measured improvement in worst abdominal pain and composite pain score using the Pain Frequency-Severity-Duration (PFSD) scale. Participants with less than 1 week of data and those with organic disease identified after enrolment were excluded from the modified intention-to-treat population. This trial has been completed and is registered with ClinicalTrials.gov, number NCT02367729. FINDINGS: Between June 18, 2015, and Nov 17, 2016, 115 children with abdominal pain-related functional gastrointestinal disorders were enrolled and assigned to either PENFS (n=60) with an active device or sham (n=55). After exclusion of patients who discontinued treatment (n=1 in the PENFS group; n=7 in the sham group) and those who were excluded after randomisation because they had organic disease (n=2 in the PENFS group; n=1 in the sham group), 57 patients in the PENFS group and 47 patients in the sham group were included in the primary analysis. Patients in the PENFS group had greater reduction in worst pain compared with sham after 3 weeks of treatment (PENFS: median score 5·0 [IQR 4·0-7·0]; sham: 7·0 [5·0-9·0]; least square means estimate of change in worse pain 2·15 [95% CI 1·37-2·93], p<0·0001). Effects were sustained for an extended period (median follow-up 9·2 weeks [IQR 6·4-13·4]) in the PENFS group: median 8·0 (IQR 7·0-9·0) at baseline to 6·0 (5·0-8·0) at follow-up versus sham: 7·5 (6·0-9·0) at baseline to 7·0 (5·0-8·0) at follow-up (p<0·0001). Median PFSD composite scores also decreased significantly in the PENFS group (from 24·5 [IQR 16·8-33.3] to 8·4 [3·2-16·2]) compared with sham (from 22·8 [IQR 8·4-38·2] to 15·2 [4·4-36·8]) with a mean decrease of 11·48 (95% CI 6·63-16·32; p<0·0001) after 3 weeks. These effects were sustained at extended follow-up in the PENFS group: median 24·5 (IQR 16·8-33·3) at baseline to 12 (3·6-22·5) at follow-up, compared with sham: 22·8 (8·4-38·2) at baseline to 16·8 (4·8-33·6) at follow-up (p=0·018). Ten patients reported side-effects (three of whom discontinued the study): ear discomfort (n=6; three in the PENFS group, three in the sham group), adhesive allergy (n=3; one in the PENFS group, two in the sham group), and syncope due to needle phobia (n=1; in the sham group). There were no serious adverse events. INTERPRETATION: Our results show that PENFS with Neuro-Stim has sustained efficacy for abdominal pain-related functional gastrointestinal disorders in adolescents. This safe and effective approach expands treatment options and should be considered as a non-pharmacological alternative for these disorders.

A randomized placebo-controlled trial on the effects of Menthacarin, a proprietary peppermint- and caraway-oil-preparation, on symptoms and quality of life in patients with functional dyspepsia.

BACKGROUND: Functional dyspepsia (FD) is a very common condition affecting more than 10% of the population. While there is no cure, a few drugs have been found to be effective for the relief of symptoms, although most are only effective in a subgroup of patients. We assess and compare the efficacy of a fixed peppermint/caraway-oil-combination (Menthacarin) on symptoms and quality of life (QoL) in patients with FD symptoms consistent with epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS). METHODS: In a prospective, double-blind, multicenter trial, 114 outpatients with chronic or recurrent FD were randomized and treated for 4 weeks with the proprietary peppermint- and caraway-oil-preparation Menthacarin or placebo (2×1 capsule/day). Improvement of abdominal pain and discomfort were used as co-primary efficacy measures (scores measured with the validated Nepean Dyspepsia Index). KEY RESULTS: After 2 and 4 weeks, active treatment was superior to placebo in alleviating symptoms consistent with PDS and EPS (P all <.001). After 4 weeks of treatment, pain and discomfort scores improved by 7.6±4.8 and 3.6±2.5 points (full analysis set; mean±SD) for Menthacarin and by 3.4±4.3 and 1.3±2.1 points for placebo, respectively. All secondary efficacy measures showed advantages for Menthacarin. CONCLUSIONS & INFERENCES: Menthacarin is an effective therapy for the relief of pain and discomfort and improvement of disease-specific QoL in patients with FD and significantly improves symptoms consistent with EPS and PDS.

Beta-glucan, inositol and digestive enzymes improve quality of life of patients with inflammatory bowel disease and irritable bowel syndrome.

OBJECTIVE: To evaluate the efficacy of a mixture of beta-glucan, inositol and digestive enzymes in improving gastrointestinal symptoms in patients affected by inflammatory bowel disease (IBD)-irritable bowel syndrome (IBS). PATIENTS AND METHODS: The study was conducted at the IBD Unit of the University of Catanzaro. Forty-three IBD patients with IBS symptoms were included in the study. IBD diagnosis was performed by clinical, endoscopic, histological and radiological criteria. Patients were in clinical remission and in treatment only with systemical and topical mesalamine. All study participants fulfilled the Rome III criteria for the diagnosis of IBS. The study participants were randomized into 2 groups: group A (n=23) received conventional treatment (systemical and topical mesalamine) plus a mixture of beta-glucan, inositol and digestive enzymes (one tablet after lunch and dinner) for four consecutive weeks; group B (n=20) received only conventional treatment. The prevalence and intensity of gastrointestinal (GI) symptoms were evaluated both at the enrollment (T0) and after four weeks of treatment (T1). RESULTS: Patients who received mesalamine plus the mixture of beta-glucan, inositol and digestive enzymes (group A) reported a reduction in abdominal pain together with reduction in bloating and flatulence after four weeks of treatment. Importantly, an overall improvement in the general well-being has been recorded. Patients who underwent only mesalamine treatment (group B) reported a mild reduction in the evacuative urgency without any other improvements. CONCLUSIONS: We have shown that supplementation with a mixture of beta-glucan, inositol and digestive enzymes reduces bloating, flatulence and abdominal pain, improving the overall clinical condition of IBD-IBS patients.

Diagnóstico y tratamiento de la enfermedad diverticular del colon derecho: revisión de conjunto / Diagnosis and management of right colonic diverticular disease: A review

El objetivo de esta revisión es definir las características clínico-patológicas y aclarar el tratamiento de la enfermedad diverticular del colon derecho. Es poco frecuente en Europa, Estados Unidos y Australia, y más común en Asia. Durante los últimos años, su incidencia ha aumentado en Occidente, con diferentes distribuciones entre poblaciones. Muchos estudios han mostrado que es difícil diferenciar antes de la cirugía los síntomas de presentación de esta enfermedad de los de la apendicitis, ya que los síntomas y signos son similares, por lo que no es infrecuente encontrarse con un diagnóstico incorrecto. Con estudios de diagnóstico por la imagen exactos es posible establecer un diagnóstico preoperatorio preciso a fin de evaluar una estrategia de tratamiento adecuada. Actualmente, el tratamiento de esta enfermedad no está bien definido, no se han propuesto recomendaciones claras y no se sabe si también se pueden aplicar las recomendaciones para la enfermedad diverticular del colon izquierdo. Varios autores han señalado que el tratamiento conservador es el mejor enfoque, incluso en caso de reincidencia, y que la cirugía solo estaría indicada en determinados casos

The aim of this narrative review is to define the clinical-pathological characteristics and to clarify the management of right colonic diverticular disease. It is rare in Europe, USA and Australia and more common in Asia. In the recent years its incidence has increased in the West, with various distributions among populations. Many studies have reported that it is difficult to differentiate the presenting symptoms of this disease from those of appendicitis before surgery, because the signs and symptoms are similar, so misdiagnosis is not infrequent. With accurate imaging studies it is possible to reach a precise preoperative diagnosis, in order to assess an accurate treatment strategy. Currently the management of this disease is not well defined, no clear guidelines have been proposed and it is not known whether the guidelines for left colonic diverticular disease can also be applied for it. Several authors have stated that conservative management is the best approach, even in case of recurrence, and surgery should be indicated in selected cases

Prevalence of pelvic floor disorders in women with suspected gynecological malignancy: a survey-based study.

INTRODUCTION AND HYPOTHESIS: Understanding of pelvic floor disorders among women with gynecological cancer is limited. The objective of this study was to describe the prevalence of pelvic floor disorders in women with suspected gynecological malignancy before surgery. METHODS: A cross-sectional study was performed of women aged ≥18 with a suspected gynecological malignancy who enrolled in the University of North Carolina Health Registry/Cancer Survivorship Cohort (HR/CSC) from August 2012 to June 2013. Demographics were obtained from the HR/CSC self-reported data; clinical data were abstracted from the electronic medical record. Subjects completed validated questionnaires (Rotterdam Symptom Checklist and the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms) to assess bladder and bowel function. RESULTS: Among 186 women scheduled for surgery for gynecological malignancy, 152 (82 %) completed baseline assessments before surgery. Mean age was 58.1 ± 13.3 years, and mean BMI was 33.6 ± 8.8 kg/m(2). The majority of subjects had uterine cancer (61.8 %), followed by ovarian (17.1 %) and cervical (11.1 %). At baseline, the rate of urinary incontinence (UI) was 40.9 %. A third of subjects reported stress UI, and one quarter reported urge UI. The overall rate of fecal incontinence was 3.9 %, abdominal pain was 47.4 %, constipation was 37.7 %, and diarrhea was 20.1 %. When comparing cancer types, there were no differences in pelvic floor symptoms. CONCLUSION: Pelvic floor disorders are common in women with suspected gynecological malignancy at baseline before surgery. Recognizing pelvic floor disorders in the preoperative setting will allow for more individualized, comprehensive care for these women.

Buyers beware: lead poisoning due to Ayurvedic medicine.

A 29-year-old man, who recently emigrated from India, presented with a 2-week history of abdominal pain, as well as nausea, constipation, and fatigue. He underwent removal of a parathyroid adenoma 6 weeks prior to admission and received a locally made Indian traditional medicine (Ayurveda) for pain control; however, this information was not initially available. He was instructed to take approximately 15 g/day. Initial evaluation revealed a normocytic anemia, but other workup including imaging and endoscopy was unrevealing. Given his recent use of Ayurvedic medicines, we tested for lead poisoning and found a blood lead level of 72 mcg/dl. We sent his medicine for analysis and found it had a high lead concentration of 36,000 mcg/g, which is over 25,000 times the maximum daily dose. He improved with cessation of the medicine and treatment with succimer. Lead poisoning can present with a variety of nonspecific signs and symptoms, including abdominal pain and anemia. Ayurvedic medicines, as well as traditional medicines from other cultures, may be a source of lead or other heavy metals. It is essential for physicians to be aware of adverse effects of Ayurvedic medicines as they are easily available and increasing in popularity.
