BACKGROUND/AIMS
According to the Chicago classification version 3.0, high-resolution manometry (HRM) should be performed in the supine position. However, with the patient in the upright/sitting position, the test could more closely simulate real-life behavior and may be better tolerated. We performed a systematic review of the literature to search whether the manometric variables and the final diagnosis are affected by positional changes.
METHODS
A literature search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies published in English that compared HRM results in different body positions were included. Moreover, the change in diagnosis of esophageal motility disorders according to the shift of body position was investigated.
RESULTS
Seventeen studies including 1714 patients and healthy volunteers met the inclusion criteria. Six studies showed a significant increase in lower esophageal sphincter basal pressure in the supine position. Integrated relaxation pressure was significantly higher in the supine position in 10 of 13 studies. Distal contractile index was higher in the supine position in 9 out of 10 studies. One hundred and fifty-one patients (16.4%) out of 922 with normal HRM in the supine position were diagnosed with ineffective esophageal motility (IEM) when the test was performed in the upright position ( < 0.001).
CONCLUSIONS
Performing HRM in the upright position affects some variables and may change the final manometric diagnosis. Further studies to determine the normal values in the sitting position are needed.

World Journal of Gastrointestinal... Aug 2016To evaluate the efficacy and safety of botulinum toxin type A (BTX-A) in the management of patients with anismus.
AIM
To evaluate the efficacy and safety of botulinum toxin type A (BTX-A) in the management of patients with anismus.
METHODS
An organized search of published literature was conducted using electronic databases including: PubMed/MEDLINE, and Cochrane Central Register of Controlled Trials, also an internet-based search using "Google Scholar" service was conducted. Both comparative and observational studies were included. We excluded irrelevant articles, editorials, case reports, reviews, and meta-analyses. The studies that followed the patients less than 6 mo were excluded. Variables collected were demographic data of the patients, technique of BTX-A injection and number of sessions, short-term and long-term clinical improvement, post-injection changes in electromyography (EMG), defecography, manometry, and balloon expulsion test, and complications recorded after BTX-A injection.
RESULTS
Seven studies comprising 189 patients were included in the review. The median age of the patients was 41.2 years and female-to-male ratio was 1.3:1. The median dose of BTX-A injected per procedure was 100 IU (range, 20-100 IU). Lateral injection was done in five trails and combined lateral and posterior injections in two trials. Three studies used endorectal ultrasonography-guided technique, one study used EMG-guided technique, whereas the remaining three studies used manual palpation with the index finger. The median percentage of patients who reported initial improvement of symptoms was 77.4% (range 37.5%-86.7%), this percentage declined to a median of 46% (range 25%-100%) at 4 mo after injection of BTX-A. Rates of improvement evaluated by balloon expulsion test, EMG, and defecography ranged between (37.5%-80%), (54%-86.7%), and (25%-86.6%), respectively. Fourteen (7.4%) patients developed complications after injection of BTX-A. Complication rates across the studies ranged from 0% to 22.6%.
CONCLUSION
Initial satisfactory improvement of symptoms after BTX-A injection remarkably deteriorated after 3 mo of the procedure. However, repeated injection may provide better sustained results with no additional morbidities. Further analysis of more patients is necessary to conclude the safety of BTX-A for the treatment of anismus.

With the advent of high-resolution esophageal manometry, it is recognized that the antireflux barrier receives a contribution from both the lower esophageal sphincter (intrinsic sphincter) and the muscle of the crural diaphragm (extrinsic sphincter). Further, an increased intra-abdominal pressure is a major force responsible for an adaptive response of a competent sphincter or the disruption of the esophagogastric junction resulting in gastroesophageal reflux, especially in the presence of a hiatal hernia. This review describes how the pressure dynamics in the lower esophageal sphincter were discovered and measured over time and how this has influenced the development of antireflux surgery.

AIM
The functional lumen imaging probe (FLIP) is a recently developed technique to evaluate the esophagogastric junction (EGJ) distensibility. Unlike timed barium esophagogram (TBE) and high-resolution manometry (HRM), FLIP can be used during peroral endoscopic myotomy (POEM). The aim of this study was to evaluate the association of intraoperative FLIP parameters with clinical outcomes as recorded in a single-center database and to investigate a systematic review of literatures.
METHODS
We reviewed consecutive patients diagnosed with achalasia and scheduled for POEM between June 2016 and March 2019 in our tertiary referral hospital. All patients underwent intraoperative FLIP assessment during POEM. The final FLIP measurements were compared between the patients with good and poor clinical response. We comprehensively reviewed studies evaluating whether intraoperative FLIP measurements reflected clinical outcomes.
RESULTS
We evaluated 23 patients with achalasia who underwent intraoperative FLIP before and after POEM. Two exhibited poor clinical responses after 3 months (Eckardt scores = 3). The final distensibility index (DI) did not differ significantly between good and poor responders (5.01 [4.52] vs. 4.91 [3.63-6.20] mm2/mmHg at a balloon distension of 50-mL, median [IQR], P = 0.853). The final DI did not differ significantly between post-POEM reflux esophagitis and non-reflux esophagitis groups (6.20 [5.15] vs. 4.23 [1.79] mm2/mmHg at a balloon distension of 50-mL, median [IQR], P = 0.075).
CONCLUSIONS
A systematic review of both prospective and retrospective studies including our data indicated that the final intraoperative FLIP measurements did not differ significantly between good and poor responders. Further study with more patients is necessary to explore whether FLIP can predict short- and long-term clinical responses.

Esophageal achalasia is classified into three subtypes according to manometric findings. Since several factors, including clinical characteristics and treatment response, have been reported to differ among the subtypes, the underlying pathogenesis may also differ. However, a comprehensive understanding regarding the differences is still lacking. We therefore performed a systematic review of the differences among the three subtypes of achalasia to clarify the current level of comprehension. In terms of clinical features, type III, which is the least frequently diagnosed of the three subtypes, showed the oldest age and most severe symptoms, such as chest pain. In contrast, type I showed a higher prevalence of lung complications, and type II showed weight loss more frequently than the other types. Histopathologically, type I showed a high loss of ganglion cells in esophagus, and on a molecular basis, type III had elevated serum pro-inflammatory cytokine levels. In addition to peristalsis and the lower esophageal sphincter (LES) function, the upper esophageal sphincter (UES) function of achalasia has attracted attention, as an impaired UES function is associated with severe aspiration pneumonia, a fatal complication of achalasia. Previous studies have indicated that type II shows a higher UES pressure than the other subtypes, while an earlier decline in the UES function has been confirmed in type I. Differences in the treatment response are also crucial for managing achalasia patients. A number of studies have reported better responses in type II cases and less favorable responses in type III cases to pneumatic dilatation. These differences help shed light on the pathogenesis of achalasia and support its clinical management according to the subtype.

BMC Anesthesiology Feb 2024To evaluate and summarize literature pertaining to evidence of peripheral arterial catheterization in adults, and to provide a reference for clinical practice.
OBJECTIVE
To evaluate and summarize literature pertaining to evidence of peripheral arterial catheterization in adults, and to provide a reference for clinical practice.
METHODS
We undertook a systematic review of literature on the removal of peripheral arterial manometric catheters in adult patients from various sources such as UpToDate, BMJ, National Institute for Health and Care Excellence (NICE), Medlive, Cochrane Library, Joanna Briggs Institute (JBI) Evidence-based Health Care Center Database, CINAHL, PubMed, Wanfang Data, VIP, and other databases. The retrieval time was set as from the establishment of the database till August 30, 2021. We screened the studies that fulfilled the inclusion criteria, evaluated their quality, and retrieved and summarized such articles.
RESULTS
The review included 8 articles: 1 clinical decision, 3 guidelines, 2 evidence summaries, 1 systematic review, and 1 expert consensus. In all, 17 pieces of strong evidence were collected and extracted based on the following 5 dimensions: assessment of removal timing, preparation before removal, removal procedure, compression time, and key points after removal.
CONCLUSIONS
The removal of a peripheral arterial manometry catheter requires careful consideration by medical professionals. In order to increase the removal standardization rate and decrease the incidence of clinical complications, standardized procedures and training need to be developed.

BACKGROUND
Urinary incontinence (UI) is defined as any involuntary urine loss that predominantly affects older women. There is evidence that pelvic floor muscles training (PFMT) program is effective on the treatment of pelvic floor (PF) dysfunctions and is considered to be first-line treatment. The evaluation of pelvic floor muscles (PFM) function and strength is central to validate the effectiveness of the training protocol in UI decrease. The Oxford Grading Scale and manometry are fundamental to evaluate the PFM function and strength.
OBJECTIVE
The aim of the study was to systematize the scientific evidence about the effects of PFMT in older women, assessing the PF function and strength through Oxford Grading Scale and manometry.
METHODS
The research of randomized controlled clinical trials was performed through B-on, EBSCO, PEDro, Pubmed, and SciELO data carried out from 2003 to 2016.
RESULTS
A total of 35 studies were identified, 26 of these were selected and fully analyzed. From the analyzed studies (n = 26), 20 were excluded for not meeting the criteria for inclusion, and only 6 studies were classified as high methodological quality, scoring an overall 4 points according the PEDro scale.
CONCLUSION
The PFMT seems to be effective in treating UI in older women; the Oxford Grading Scale and manometry are considered the most reliable in the random and controlled clinical trials results. However, future investigations with high methodological quality with older women are necessary to support these results.

Upper-GI diseases are one of the most relevant issue in primary care. Nowadays they are still responsible for about 100 million ambulatory care visits only in the US. The diagnosis of almost every upper-GI condition is still deputed to invasive tests such as upper gastrointestinal endoscopy, gastroesophageal manometry or radiography. The possibility of analysing serum markers like Pepsinogens I and II, produced by gastric mucosa, in order to assess the functional characteristics of the upper GI tract has spread itself since the 80's especially in the diagnosis of peptic ulcer. The discovery of Helicobacter pylori by Marshall and Warren in 1983 and the scientific consecration of its role in the pathogenesis of gastric cancer and peptic ulcer (crystallized in Peleo Correa's Cascade, 1992), led to an increase importance of non-invasive tests, raising the attention towards the assessment of both immunoglobulins anti-H.p. and Gastrin hormone produced by antral G cells, as an implementation of the panel of gastric markers. This narrative review aims to analyze the huge landscape of non-invasive tests for diagnosis of GI diseases, studying the literature of the recent years.

Achalasia is a rare esophageal disorder characterized by abnormal esophageal motility and swallowing difficulties. Pain and/or spasms often persist or recur despite effective relief of the obstruction. A survey by UK charity 'Achalasia Action' highlighted treatments for achalasia pain/spasms as a key research priority. In this patient-requested systematic review, we assessed the existing literature on pharmacological therapies for painful achalasia. A systematic review of the literature using Medline, Embase and Cochrane databases was performed to identify studies evaluating pharmacological therapies for achalasia. Methodological quality of included randomized controlled trials was assessed using the Cochrane Risk of Bias tool. In total, 70% (40/57) of survey respondents reported experiencing pain/spasms. A range of management strategies were reported. Thirteen studies were included in the review. Seven were randomized controlled trials. Most studies were >30 years old, had limited follow-up, and focussed on esophageal manometry as the key endpoint. Generally, studies found improvements in lower esophageal pressures with medications. Only one study evaluated pain/spasm specifically, precluding meta-analysis. Overall risk of bias was high. The achalasia patient survey identified that pain/spasms are common and difficult to treat. This patient-requested review identified a gap in the literature regarding pharmacological treatments for these symptoms. We provide an algorithm for investigating achalasia-related pain/spasms. Calcium channel blockers or nitrates may be helpful when esophageal obstruction and reflux have been excluded. We advocate for registry-based clinical trials to expand the evidence base for these patients.

INTRODUCTION
Epiphrenic diverticula (ED) are infrequent and conventional surgical treatment entails aggressive open or transthoracic surgery. Minimally invasive treatment has changed the surgical approach but some surgical controversies are not resolved.
OBJECTIVE
The objective of this study is to describe our experience in minimally invasive treatment of the ED and to perform a systematic review of the current literature in this subject.
MATERIALS AND METHODS
We reviewed all data from the Hospital de Sant Pau, focusing on patients that underwent minimally invasive treatment for an ED since 1998 to date. Furthermore, we performed a systematic literature review focused on the minimally invasive approach for ED.
RESULTS
A total of 6 patients have been treated (5 transhiatal and 1 with abdominal and thoracic approach). We found a predominance of males with a median age of 63. The diagnosis was made with an endoscopy, barium swallow and manometry. Half of the manometry results were pathologic. The surgical technique involved a diverticulectomy, myotomy and a Dor partial founduplication. Two patients that presented suture line leakage (SLL) were treated conservatively. No mortality was reported. The systematic review was carried out under the Preferred Reporting Items for Systematic Reviews and Meta-analyses scheme, with a total of 20 studies where 189 patients were found. No comparative or prospective randomised trials were found. Overall morbidity was 24%, with a SLL rate of 12%, hospital stay of 5 days and mortality of 1.5%. After a median follow-up of 42 months, 81.5% of the patients were asymptomatic.
CONCLUSION
The minimally invasive approach for ED is a safe and feasible procedure.
