Background and objective: Little is known about the clinical impact of double-balloon enteroscopy (DBE) in patients with PeutzJeghers syndrome (PJS).The aim of this study was to assess the efficacy and safety of DBE in the management of small-bowel polyps in PJS patients.Patients and methods: We conducted a multicentre, retrospective cohort study, which included all consecutive patients diagnosed with PJS who underwent DBE for polypectomy between January 2006 and August 2012. In all cases, previous videocapsule enteroscopy had shown at least one polyp ≥ 10 mm in size.Results: Twenty-five patients (13 men; median age 36 years; 14 with prior laparotomy) underwent 46 DBE procedures (1 to 5 per patient, 44 via oral route). Polypectomy was performed in 39/46 DBEs. A total of 214 polyps were removed (median-size 30 mm), with a median number of polypectomies per procedure of 5.0 (range 1-18). The estimated maximum-sizes of resected polyps significantly decreased at each session: 30.0, 25.0, 20.0, 15.0, and 17.5 mm (p = 0.02). In 7 DBEs no polypectomy was performed (4-only minor polyps detected; 3-endoscopic irresecability). Complications occurred in 3/39 of therapeutic procedures (2-minor delayed bleeding; 1-mucosal tear), all of them dealt with conservative or endoscopic therapy. Six patients underwent elective surgery post DBE due to polyps not amenable for endoscopic resection. There were no small-bowel polyp related complications during a median follow-up of 56.5 months.Conclusion: DBE showed to be a safe and effective technique in the management of small-bowel polyps in PJS patients, allowing a presymptomatic and non-surgical approach.

IntroductionIrritable bowel syndrome (IBS) is a functional bowel disorder characterized by chronic or recurrent abdominal pain in association with defecation or a change in bowel habits. A predominant disorder of bowel habits, IBS is classified into three main subtypes: constipation-predominant IBS (IBS-C), diarrhea-predominant IBS (IBS-D) and IBS alternating between constipation and diarrhea (IBS-M). Linaclotide is a first-in-class, oral, once-daily guanylate cyclase-C receptor agonist (GC-CA) that is licensed for the symptomatic treatment of moderate-to-severe IBS-C in adults. This review aims to facilitate and optimize clinical practices, establishing common guidelines to monitor patients with IBS-C that are treated with linaclotide.MethodsA group of experts in functional digestive disorders was convened to review the efficacy and safety of linaclotide and to develop an updated consensus report for the treatment of patients with IBS-C. A search was performed for English, French and Spanish language articles in PubMed. On the basis of the articles identified, an initial document was drafted addressing different issues frequently raised by general practitioners and GI specialists that are related to the prescription, efficacy and safety of linaclotide. This document was then reviewed and modified by the expert panel until a final text was agreed upon and validated.ResultsBased on the evidence, the panel addressed the following recommendations: (1) Linaclotide is indicated for the treatment of moderate to severe IBS-C in adults; (2) it is recommended that patients take linaclotide continuously and not sporadically; (3) patients should be warned about the risk of diarrhea and given choices concerning how to deal with this possible side effect; (4) the absence of tachyphylaxis or potential risks implies that linaclotide treatment can be maintained for long periods of time.ConclusionsThis document seeks to lay down a set of recommendations and to identify key issues that may be useful for the clinical management of IBS-C patients treated with linaclotide.

More than half of the patients had rebleeding after 5 years of follow-up, although transfusion requirements decreased. Patients with high-risk comorbidities are more likely to rebleed.
