Neurogastroenterol Motil 2024; 36:e14791. [PMID: 38587047 DOI: 10.1111/nmo.14791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/14/2024] [Accepted: 03/19/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND The functional lumen imaging probe (FLIP) is a test of anal sphincter distensibility under evaluation by specialist centers. Two measurement protocols termed "stepwise" and "ramp" are used, risking a lack of standardization. This study aims to compare the performance of these protocols to establish if there are differences between them. METHODS Patients with fecal incontinence were recruited and underwent measurement with both protocols at a tertiary pelvic floor referral unit. Differences in minimum diameter, FLIP bag pressure, and distensibility index (DI) at rest and during squeeze were calculated at various FLIP bag volumes. KEY RESULTS Twenty patients (19 female, mean age 61 [range: 38-78]) were included. The resting minimum diameter at 30 and 40 mL bag volumes were less in the stepwise protocol (mean bias: -0.55 mm and -1.18 mm, p < 0.05) along with the DI at the same bag volumes (mean bias: -0.37 mm2/mmHg and -0.55 mm2/mmHg, p < 0.05). There was also a trend towards greater bag pressures at 30 mL (mean bias: +2.08 mmHg, p = 0.114) and 40 mL (mean bias: +2.81 mmHg, p = 0.129) volumes in the stepwise protocol. There were no differences between protocols in measurements of minimum diameter, maximum bag pressure, or DI during voluntary squeeze (p > 0.05). CONCLUSION AND INFERENCES There are differences between the two commonly described FLIP measurement protocols at rest, although there are no differences in the assessment of squeeze function. Consensus agreement is required to agree the most appropriate FLIP measurement protocol in assessing anal sphincter function.

Clin Res Hepatol Gastroenterol 2024; 48:102275. [PMID: 38158155 DOI: 10.1016/j.clinre.2023.102275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 12/13/2023] [Accepted: 12/27/2023] [Indexed: 01/03/2024]
Abstract
PURPOSE Three subtypes of fecal incontinence (FI) are described in the literature: urge, mixed and passive FI, but the relevance of this classification remains unknown. To our knowledge, no questionnaire has been validated in a general population of patients with FI to classify patients between the different subtypes of FI. The aim of the present study was to validate the Fecal Incontinence Subtype Assessment (FI-SA) questionnaire in a general population of patients with FI. METHODS All consecutive patients referred to our unit for physiological investigations of anorectal function in case of FI were included. A feasibility study was done to assess the acceptability, understanding, and the reproducibility of the FI-SA questionnaire. Its performance to correctly classify patients between subtypes of FI was evaluated in both a feasibility study and in a validation study, using clinical interview as gold standard. RESULTS The FI-SA questionnaire was found to be well accepted and easily understood by patients. Moreover, it was filled rapidly by patients, with a good reproducibility with an intra-class correlation coefficient of 0.97 and 0.87 for questions 1 and 2. Lastly, the accuracy of the FI-SA questionnaire to predict subtypes of FI was 93.3 % in the feasibility study (n = 30) and 81.1 % in the validation study (n = 100), in comparison with clinical interview as gold standard. CONCLUSION The FI-SA questionnaire could be used in the future to help standardize the methodology used among studies to evaluate the classification of patients in different subtypes of FI and ultimately to guide therapeutics.

White E, Mutalib M. Use of endolumenal functional lumen imaging probe in investigating paediatric gastrointestinal motility disorders. World J Clin Pediatr 2023; 12:162-170. [PMID: 37753495 PMCID: PMC10518749 DOI: 10.5409/wjcp.v12.i4.162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 08/09/2023] [Accepted: 08/23/2023] [Indexed: 09/06/2023] Open
Abstract
Investigating gastrointestinal (GI) motility disorders relies on diagnostic tools to assess muscular contractions, peristalsis propagation and the integrity and coordination of various sphincters. Manometries are the gold standard to study the GI motor function but it is increasingly acknowledged that manometries do not provide a complete picture in relation to sphincters competencies and muscle fibrosis. Endolumenal functional lumen imaging probe (EndoFLIP) an emerging technology, uses impedance planimetry to measure hollow organs cross sectional area, distensibility and compliance. It has been successfully used as a complementary tool in the assessment of the upper and lower oesophageal sphincters, oesophageal body, the pylorus and the anal canal. In this article, we aim to review the uses of EndoFLIP as a tool to investigate GI motility disorders with a special focus on paediatric practice. The majority of EndoFLIP studies were conducted in adult patients but the uptake of the technology in paediatrics is increasing. EndoFLIP can provide a useful complementary data to the existing GI motility investigation in both children and adults.
