Review
The sphincter of Oddi is a delicate neuromuscular structure located at the junction of the biliary-pancreatic system and the duodenum. Sphincter of Oddi Dysfunction (SOD) can result in various clinical manifestations, including biliary-type pain and recurrent idiopathic pancreatitis. The management of SOD has been challenging. With the publication of the landmark Evaluating Predictors and Interventions in Sphincter of Oddi Dysfunction (EPISOD) trial and the Rome IV consensus, our clinical practice in the treatment of SOD has changed significantly in recent years. Currently, the management of type II SOD remains controversial and there is a lack of non-invasive therapy options, particularly for patients not responding to endoscopic treatment. In this mini review, we aimed to discuss the current knowledge on the treatment of biliary SOD.

PURPOSE OF REVIEW
Over the last few decades, there have been remarkable strides in endoscopy and radiological imaging that have advanced gastroenterology. However, the management of neurogastroenterological disorders has lagged behind, in part handicapped by the use of catheter-based manometry that is both non-physiological and uncomfortable. The advent of capsule technology has been a game changer for both diagnostic and therapeutic applications.
RECENT FINDINGS
Here, we discuss several capsule devices that are available or under investigation. There are three technologies that are FDA approved. Wireless motility capsule measures pH and pressure and provides clinically impactful information regarding gastric, small intestine and colonic transit, without radiation that has been demonstrated to guide management of gastroparesis, dyspepsia and constipation. Wireless ambulatory pH monitoring capsule is currently the gold standard for assessing gastroesophageal acid reflux. In the therapeutics arena, an orally ingested vibrating capsule has been recently FDA approved for the treatment of chronic constipation, supported by a robust phase 3 clinical trial which showed significant improvement in constipation symptoms and quality of life. There are several capsules currently under investigation. Smart capsule bacterial detection system and Capscan® are capsules that can sample fluid in the small or large bowel and provide microbiome analysis for detection of small intestinal bacterial (SIBO) or fungal overgrowth (SIFO). Another investigational gas sensing capsule analyzing hydrogen, CO volatile fatty acids and capsule orientation, can measure regional gut transit time and luminal gas concentrations and assess gastroparesis, constipation or SIBO. Therapeutically, other vibrating capsules are in development. Innovations in capsule technology are poised to transform our ability to investigate gut function physiologically, and non-invasively deliver targeted treatment(s), thereby providing both accurate diagnostic information and luminally-directed, safe therapy.

Robotic-assisted myotomy with partial fundoplication for patients with achalasia has been established as a safe and effective procedure with similar short-term results and lower rates of intraoperative esophageal perforations. Our aim was to investigate a defined patient cohort undergoing robotic-assisted and laparoscopic surgery providing pre- and postoperative symptom score and high-resolution manometry to evaluate the clinical and functional outcome.All patients underwent clinical, endoscopic, radiological and manometric investigation to verify the diagnosis of achalasia. High-resolution manometry was performed preoperatively and 6 months postoperatively and categorized according to the Chicago Classification (v4.0). We used the Eckardt Score to evaluate symptomatic outcome. All patients underwent either robotic-assisted or laparoscopic myotomy with partial anterior fundoplication (180° Dor) using the DaVinci Xi surgical system (Intuitive, Sunnyvale, California, USA). From a total amount of 101 patients, we analyzed the data of 78 (47 robotic and 31 laparoscopic) procedures between 2015 and 2020. All patients showed a significant decrease of the Eckardt Score in the robotic group (median 6 vs. 2) as well as in the laparoscopic group (median 7.5 vs. 3). The postoperative LESP and 4 s-IRP was significantly reduced in all patients in the robotic group [median LESP (mmHg) 34.16 vs. 16.9; median 4 s-IRP (mmHg) 28.85 vs. 14.55], as well as in the laparoscopic group [median LESP (mmHg) 35.34 vs. 17.3; median 4 s-IRP (mmHg) 25.6 vs. 15.9]. There was no significant difference for these parameters between the groups. There was no event of intraoperative esophageal perforation in the robotic cohort, whereas there were 2 in the laparoscopic group. Our data support the safe and effective robotic approach for the surgical treatment of achalasia. Not only the clinical outcome but also the functional results measured by high-resolution manometry are similar to the laparoscopic procedure. Further investigations in larger prospective multicenter studies are needed.

BACKGROUND
Although dysphagia and chest pain are the two most common symptoms in patients with achalasia, the mechanism of evoking symptoms is still unknown. The aim of this study was to reveal the relationship between symptoms and the subtypes of achalasia defined by the Chicago classification.
METHODS
A total of 71consecutive patients with newly diagnosed achalasia were enrolled between March 2009 and December 2017. Esophageal motility was assessed by high-resolution manometry (HRM) with the Chicago classification v 3.0. and esophagograms. Their symptoms were evaluated with structured self-reported questionnaires focused on dysphagia and chest pain. Symptom profiles and radiographic findings according to the manometric subtypes were investigated.
RESULTS
Among the total 71 patients, 69 patients (97%) had dysphagia and 39 patients (54%) had chest pain. Regarding dysphagia, type II patients reported dysphagia in the throat the most, while types I and III patients mostly felt it in the epigastrium. Type II patients often felt dysphagia at the time of swallowing (41%), but this was reported in only 8.7% of Type I and 33% of Type III patients (p = 0.02). Concerning chest pain, Type I patients rarely had pain during meals (14%), but more often while sleeping (43%) and in early morning (43%), while type III patients often had pain during meals (67%). Type III patients reported that solid food caused pain more often than other types (I/II/III 0/10/33%, p = 0.09).
CONCLUSIONS
Detailed symptoms of achalasia, such as its site and timing, varied by subtypes. The status of the esophageal body might induce those differences in symptoms.

OBJECTIVE
Pediatric inferior turbinate hypertrophy (PedTH) is a frequent and often overlooked cause or associated cause of nasal breathing difficulties. This clinical consensus statement (CCS) aims to provide a diagnosis and management framework covering the lack of specific guidelines for this condition and addressing the existing controversies.
METHODS
A clinical consensus statement (CCS) was developed by a panel of 20 contributors from 7 different European and North American countries using the modified Delphi method. The aim of the CCS was to offer a multidisciplinary reference framework for the management of PedTH on the basis of shared clinical experience and analysis of the strongest evidence currently available.
RESULTS
A systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria was performed. From the initial 96 items identified, 7 articles were selected based on higher-evidence items such as randomized-controlled trials, guidelines, and systematic reviews. A 34-statement survey was developed, and after three rounds of voting, 2 items reached strong consensus, 17 reached consensus or near consensus, and 15 had no consensus.
CONCLUSIONS
Until further prospective data are available, our CCS should provide a useful reference for PedTH management. PedTH should be considered a nasal obstructive disease not necessarily related to an adult condition but frequently associated with other nasal or craniofacial disorders. Diagnosis requires clinical examination and endoscopy, whereas rhinomanometry, nasal cytology, and questionnaires have little clinical role. Treatment choice should consider the specific indications and features of the available options, with a preference for less invasive procedures.

The American Journal of Gastroenterology Dec 2023The pathoetiology and treatment of levator ani syndrome (LAS) remain unclear.
INTRODUCTION
The pathoetiology and treatment of levator ani syndrome (LAS) remain unclear.
METHODS
We evaluated pathophysiology using translumbosacral motor-evoked potentials and anorectal manometry in patients with LAS and compared with healthy controls. A cohort underwent translumbosacral neuromodulation therapy (TNT).
RESULTS
Lumbar and sacral motor-evoked potential latencies were prolonged in 32 patients with LAS compared with 31 controls ( P < 0.013), with higher prevalence of anal neuropathy ( P = 0.026). TNT improved anorectal pain ( P = 0.003) and neuropathy ( P < 0.02) in 13 patients with LAS.
DISCUSSION
Patients with LAS demonstrate significant lumbosacral neuropathy that may cause anorectal pain. TNT improved anorectal pain and neuropathy, providing a novel therapeutic option.

BACKGROUND
Achalasia sub-types affect treatment response in adults, but there is no similar data in children. We studied the differences in clinico-laboratory features and response to therapy between achalasia sub-types in children.
METHODS
Forty-eight children (boys:girls-25:23, 14 [0.9-18] years) with achalasia (clinical, barium, high-resolution manometry [HRM], gastroscopy) were evaluated. The sub-type was determined by Chicago classification at HRM. Pneumatic dilatation (PD) or surgery was the primary therapy. Success was defined as Eckhardt score of ≤ 3.
RESULTS
Dysphagia (95.8%) and regurgitation (93.8%) were the most common symptoms. Forty of 48 cases had an adequate HRM study: Type I (n-19), II (n-19) and III (n-2). Types I and II had similar clinical profile. Type II had higher basal lower esophageal sphincter (LES) pressure (30.5 [16.5-46] vs. 22.5 [13-43] mmHg; p = 0.007) and less dilated esophagus on timed barium esophagogram (TBE, 25 [13-57] vs. 34.5 [20-81] mm; p = 0.006) than type I. Both types had similar success (86.6% [13/15] vs. 92.8% [13/14]; p = 1) after first PD and need of post-PD myotomy (5/17 vs. 1/16; p = 0.1) in follow-up. Twenty-three cases had TBE before and after PD; 15 (65.2%) had good clearance. These subjects required myotomy (1/15 vs. 4/8; p = 0.03) and repeat PD (5/15 vs. 4/8; p = 0.08) less often than those with poor clearance on TBE.
CONCLUSION
Types I and II achalasia have similar frequency and clinical profile. Type II has higher LES pressure and less dilated esophagus than Type I. Both respond equally well to initial PD. Type I required post-PD myotomy more often, though not significantly. TBE is useful for assessing therapeutic response.

Peroral endoscopic myotomy (POEM), which has been used to treat achalasia and other esophageal motility disorders for the past 10 years, has proven to be secure and efficient. Every year, more and more essays on this subject are published. We sought to investigate the global scientific outputs and hotspots of POEM produced by various nations, organizations, and authors. From 2010 to October 2022, there were 875 papers on POEM that were found in the Web of Science Core database. The bibliometric visualization analyses of nations/regions, institutions, authors, journals, references, and keywords were conducted by CiteSpace V.5.8.R3. Eight hundred seventy-five publications were included in this analysis. With 68 publications, Inoue H had the highest output. While Showa University in Japan was the most productive institution, the United States was the most productive nation. Among the journals, Surgical Endoscopy published the highest number of articles, followed by Gastrointestinal Endoscopy and Endoscopy. The top 10 keywords that appeared most frequently were achalasia, peroral endoscopic myotomy, POEM, myotomy, esophageal achalasia, dysphagia, heller myotomy, endoscopy, gastroparesis and peroral endoscopic myotomy. Seven frontiers, including meta-analysis, high-resolution esophageal manometry, geriatric patient, third space endoscopy, adverse event, endoscopic submucosal dissection, and gastric peroral endoscopic myotomy, had an impact on future research on POEM. The previous 10 years have seen a considerable rise in POEM research, and this trend will continue. The most recent research frontiers, which require more attention, are meta-analysis, high-resolution esophageal manometry, geriatric patient, third space endoscopy, adverse event, and gastric peroral endoscopic myotomy.

BACKGROUND
In the last two decades the development of high-resolution manometry (HRM) has changed and revolutionized the diagnostic assessment of patients complain foregut symptoms. The role of HRM before and after antireflux procedure remains unclear, especially in surgical practice, where a clear understanding of esophageal physiology and hiatus anatomy is essential for optimal outcome of antireflux surgery (ARS). Surgeons and gastroenterologists (GIs) agree that assessing patients following antireflux procedures can be challenging. Although endoscopy and barium-swallow can reveal anatomic abnormalities, physiologic information on HRM allowing insight into the cause of eventually recurrent symptoms could be key to clinical decision making.
METHOD
A multi-disciplinary international working group (14 surgeons and 15 GIs) collaborated to develop consensus on the role of HRM pre- and post- ARS, and to develop a postoperative classification to interpret HRM findings. The method utilized was detailed literature review to develop statements, and the RAND/University of California, Los Angeles Appropriateness Methodology (RAM) to assess agreement with the statements. Only statements with an approval rate >80% or a final ranking with a median score of 7 were accepted in the consensus. The working groups evaluated the role of HRM prior to ARS and the role of HRM following ARS.
CONCLUSION
This international initiative developed by surgeons and GIs together, summarizes the state of our knowledge of the use of HRM pre- and post-ARS. The Padova Classification was developed to facilitate the interpretation of HRM studies of patients underwent ARS.

BACKGROUND AND AIMS
Esophageal symptoms, that is, heartburn, regurgitation, dysphagia, and chest pain are common in the general population. Also common are symptoms of back pain related to pathology in the lumbosacral spine. The right crus of the diaphragm that forms the esophageal hiatus, originates from lumbar spine, may be affected by lumbar spine pathology resulting in esophageal symptoms. We studied whether there was an association between esophageal symptoms and spine symptoms.
METHODS
Two patient groups of 150 each were investigated: group 1 (ES); patients referred to the esophageal manometry study for assessment of esophageal symptoms, group 2 (SC); patients undergoing screening colonoscopy (control group). Both groups completed standardized questionnaires assessing esophageal and spine symptoms.
RESULTS
Back pain was reported by 74% of patients in the ES group as compared to 55% of patients in the SC group. Thirty percent of patients in the SC group reported one or more esophageal symptoms and these patients were regrouped with the ES group, resulting in 2 groups, ES1 and SC1, with and without esophageal symptoms, respectively. The ES1 group was 3.3 times more likely to experience back pain compared to the SC1 group (95% confidence interval: 1.95-5.46). Thoracolumbar was the most common site of pain in both groups. Pain score was greater for the group with esophageal symptoms compared to controls. Narcotic intake for most patients in the ES1 group was for back pain.
CONCLUSION
A strong association between esophageal symptoms and thoracolumbar back pain raises the possibility that structural and functional changes in the esophageal hiatus muscles related to thoracolumbar spine pathology lead to esophageal dysmotility and symptoms.
