Position paper on transanal irrigation in chronic non-organic constipation

The practice of recto-colonic water irrigation to treat constipation has been used since ancient times with different, uncontrolled, and variably performing methods which have been considered interchangeably all alike. The use of better-performing devices with a standardized methodology is relatively recent, and the term Trans Anal Irrigation (TAI) defines a methodology performed with devices able to control the timing, volume, and pressure of the water introduced into the rectum and colon utilizing a catheter or a cone through the anus. Such practice has been implemented with favorable responses in patients with refractory chronic constipation secondary to neurological diseases. However, since the role of Trans Anal Irrigation as a therapeutic aid in chronic functional constipation and functional evacuation disorders is not yet fully clarified and standardized, a group of clinical investigators with recognized expertise in these clinical conditions intends to clarify the elements that characterize a TAI procedure that can benefit patients with functional constipation and functional defecation disorders defined according to the lastly updated Rome Diagnostic Criteria. Finally, the paper deals with adherence and practical implementation of TAI.

Azathioprine in the maintainance remission in inflammatory bowel disease patients: 7-year follow up

Background

Azathioprine (AZA) and thiopurine are widely used for induction and maintenance of remission in steroid dependent patients with inflammatory bowel disease (IBD).

Methods

Aim of this study has been to investigate its efficacy and safety in maintaining steroid-free remission in steroid dependent IBD patients seven year after the institution of treatment. Data from consecutive IBD outpatients referred in our Institution, between 1985-2016, were reviewed and all patients treated with AZA were included in this retrospective study. AZA was administered at the recommended dose of 2-2.5 mg/kg.

Results

Out of 2802 consecutive IBD outpatients visited in the index period, AZA was prescribed to 433 patients, 236 (54.5%) were affected by Crohn's disease (CD) and 197 (45.5%) by ulcerative colitis (UC). One hundred and seventy-nine patients with a follow-up < 84 months were excluded from the study. Two hundred and fifty-four patients were evaluated, 141 (55.5%) with CD and 113 (44.5%) with UC. One hundred and thirty-nine (54.7%) were male and 115 (45.3%) female (average age of 35.62 ± 14.20 SD years, range 14-74 y.). Seven year after the institution of treatment, 127 (50%) patients still were in steroid-free remission (83 CD vs 44 UC, 58.8% and 38.9%, respectively, p = 0.0024), 71 (27.9%) had a relapse requiring retreatment with steroids (29 CD vs 42 UC, 20.6% and 37.2%, respectively, p = 0.0047), 56 (22.1%) discontinued the treatment due to side effects (29 CD vs 27 UC, 20.6% and 23.9%, respectively). Loss of response from 1st to 7th year of follow-up was low, about 20%.

Conclusions

Seven year after the onset of treatment 50% of patients did not require further steroid courses. After the first year loss of response was low in six subsequent years. In the present series the maintenance of steroid-free remission was significantly higher in CD than in UC patients. The occurrence of side effects leading to the withdrawal of AZA treatment has been low.

Key messages

An important therapeutic moment of IBD is mantaining remission in steroid dipendent patients. AZA can be a viable and inexpensive alternative to treath these patients.

Rome IV. Gallbladder and Sphincter of Oddi Disorders

The concept that motor disorders of the gallbladder, cystic duct and sphincter of Oddi can cause painful syndromes is attractive and popular, at least in the USA. However, the results of commonly performed ablative treatments (cholecystectomy and sphincterotomy) are not uniformly good. The predictive value of tests that are often used to diagnose dysfunction (dynamic gallbladder scintigraphy and sphincter manometry) is controversial. Evaluation and management of these patients is made difficult by the fluctuating symptoms and the placebo effect of invasive interventions. A recent stringent study has shown that sphincterotomy is no better than sham treatment in patients with post-cholecystectomy pain and little or no objective abnormalities on investigation, so that the old concept of sphincter of Oddi dysfunction (SOD) type III is discarded. ERCP approaches are no longer appropriate in that context. There is a pressing need for similar prospective studies to provide better guidance for clinicians dealing with these patients. We need to clarify the indications for cholecystectomy in patients with Functional Gallbladder Disorder (FGBD) and the relevance of sphincter dysfunction in patients with some evidence for biliary obstruction (previously SOD type II, now called "Functional Biliary Sphincter Disorder - FBSD") and with idiopathic acute recurrent pancreatitis.

A cross-cultural investigation of attachment style, catastrophizing, negative pain beliefs, and symptom severity in irritable bowel syndrome

BACKGROUND

Little information exists regarding whether psychosocial variables in irritable bowel syndrome (IBS) vary by geographic location. Adult attachment is an important psychological concept rooted in childhood relationship experience that has not been previously studied in IBS. Catastrophizing and negative pain beliefs have been described in IBS and may be affected by attachment.

AIMS

In this cross-cultural study, we determined: (i) whether attachment differs between IBS patients and controls, (ii) whether geographic location has a significant effect on attachment style, catastrophizing and negative pain beliefs, and (iii) how all three variables correlate with IBS symptom severity.

METHODS

463 IBS patients, with moderate to severe symptom scores, and 192 healthy controls completed validated questionnaires about attachment, catastrophizing, negative pain beliefs and IBS-SSS in nine locations, USA (New York, Los Angeles), Mexico, Italy (Rome, Bari), Romania, Iran, India, and China.

KEY RESULTS

Attachment anxiety and avoidance scores were significantly higher in IBS patients than in controls (p < 0.001). This was particularly true for the fearful-avoidant attachment category, especially in China and Romania. Path analysis showed that attachment anxiety and avoidance had indirect effects on IBS-SSS through catastrophizing (p < 0.0001) and negative pain beliefs (p = 0.005). All three psychosocial measures varied significantly depending on location.

CONCLUSIONS & INFERENCES

In the IBS population studied, attachment style was significantly different in IBS compared to a control population. Geographic differences in attachment, catastrophizing and negative pain beliefs were documented and their correlation with symptom severity and thus, research of psychosocial variables in IBS should take into account the location of the population studied.

Patient with chest pain refractory to proton pump inhibitor: report of a case of eosinophilic esophagitis

Eosinophilic esophagitis (EoE) is the most common form of gastrointestinal disorders associated with eosinophilia. Typically, an inappropriate accumulation of eosinophils is found in the esophageal mucosa. EoE can be well managed and treated with several options that include an elimination diet, drug therapy (oral and topical steroids) and esophageal dilatations. We herein, report a case of a 49-year-old male affected by EoE associated to chest pain, treated with proton pump inhibitor without clinical response. The patient suffered from long lasting postprandial fullness and gastroesophageal reflux disease-like symptoms. He had a history of episodic asthmatic attacks and allergic rhinitis but had not dysphagia or food impaction. The patient recovered completely after an adequate treatment.
