PURPOSE The removal of smooth muscle during stapled hemorrhoidopexy raises concerns regarding its effects on postoperative anorectal function. The purpose of this study was to evaluate the correlation between the amount of muscle removed and changes in anorectal manometry following stapled hemorrhoidopexy. METHODS Patients with symptomatic II, III, or IV degree hemorrhoids that underwent stap...

Background/Aims Although many advances in the management of Hirschsprung's disease have recently been achieved, postoperative outcomes of these patients remain difficult in a non-negligible number of cases. Therefore, this study aims at investigating characteristics of anorectal manometry and its relationship with postoperative outcomes during long-term follow-up in Hirschsprung patients. Met...

STUDY OBJECTIVES The published AASM guidelines approve use of a nasal cannula/pressure transducer to detect apneas/hypopneas, but require esophageal manometry for Respiratory Effort-Related Arousals (RERAs). However, esophageal manometry may be poorly tolerated by many subjects. We have shown that the shape of the inspiratory flow signal from a nasal cannula identifies flow limitation and eleva...

BACKGROUND Somatostatin has been used to prevent pancreatitis after endoscopic retrograde cholangiopancreatography but its effect on acute non-biliary pancreatitis is still unclear. AIM The purpose of this study was to evaluate the function of the sphincter of Oddi (SO) and the effect of somatostatin on patients with non-biliary pancreatitis. METHODS Twenty patients (18 males, two females) ...

BACKGROUND Normal values for water-perfused esophageal high-resolution manometry have still not been established in our environment, despite its generalized use and the recommendation to determine reference values for each Motility Unit based on their equipment. Normal values established with solid-state highresolution manometry are currently being used as reference values for water-perfused hi...

We reviewed the recent literature concerning investigations of esophageal peristaltic function. The gold standard for the assessment of esophageal peristaltic function is manometry with pH monitoring. Even with this investigation modality, however, we are in fact doing no more than estimating esophageal peristaltic function from the manometry and pH results. With esophageal fluoroscopy and scin...

BACKGROUND AND AIM Anorectal manometry is used in the evaluation of disorders of the lower gastrointestinal tract: constipation, incontinence, anorectal pain. Most of these conditions are invalidating. Moreover, the patients do not benefit from a perfect therapy. Therefore many of them also use alternative therapies, but we still miss data on the use of alternative therapies in anorectal disord...
