A Rare Case of Ectocervical Pregnancy and Its Successful Management: A Case Report and Review of the Literature.

Cervical pregnancy is a very rare form of ectopic pregnancy, which can be life-threatening due to the potential risk of massive haemorrhage. The most likely site of cervical implantation is within the endocervical canal. We report here an unusual and another possible site of cervical pregnancy on the surface of the ectocervix (portio).

The Natural History of Asymptomatic Gallstones: A Longitudinal Study and Prediction Model.

Background & Aims: Despite the high prevalence of asymptomatic gallstones (AGs), there are limited data on their natural history. We aimed to determine the rate of symptom development in a contemporary population, determine factors associated with progression to symptomatic gallstones (SGs), and develop a clinical prediction model.

Methods: We used a retrospective cohort design.

Manometric Esophageal Length to Height (MELH) Ratio Predicts Hiatal Hernia Recurrence.

Introduction: The shortened esophagus is poorly defined and is determined intraoperatively, as there exists no objective test to identify a shortened esophagus before surgical hiatal hernia repair. We devised a unique manometric esophageal length to height (MELH) ratio to define the presence of a shortened esophagus and examined the role of esophageal length in hiatal hernia recurrence.

Patients And Methods: A retrospective review identified 254 patients with hiatal hernia who underwent preoperative esophageal manometry and either an open hernia repair with Collis gastroplasty and fundoplication (with Collis) or laparoscopic repair and fundoplication without Collis gastroplasty (without Collis) from 2005-2016.

Epidemiology of Large Bowel Carcinoid Tumors in the USA: A Population-Based National Study.

Background And Aims: Prior studies have shown that about 90% of all carcinoid tumors occur in the GI tract. However, epidemiological studies of these tumors have been limited by small sample size. Our aim was to obtain a more robust epidemiologic survey of large bowel carcinoids (LBC), using population-based data in order to more accurately identify risk factors for these tumors.

Cryotherapy in the management of premalignant and malignant conditions of the esophagus.

Endoscopic cryotherapy is a relatively new thermal ablative modality used for the treatment of neoplastic lesions of the esophagus. It relies on cycles of rapid cooling and thawing to induce tissue destruction with a cryogen (liquid nitrogen or carbon dioxide) leading to intra and extra-cellular damage. Surgical treatment was once considered the standard therapeutic intervention for neoplastic diseases of the esophagus and is associated with considerable rates of morbidity and mortality.

Esophageal Mucosal Impedance Patterns Discriminate Patients With Eosinophilic Esophagitis From Patients With GERD.

Background & Aims: It is a challenge to make a diagnosis of eosinophilic esophagitis (EoE) because its symptoms and histologic features overlap with those of gastroesophageal reflux disease (GERD). A minimally invasive device was recently developed to detect mucosal impedance (MI) that measures epithelial integrity during upper endoscopy. We aimed to quantify MI along the esophagus and identify patterns that differentiated patients with and without GERD from those with EoE, and determine whether MI values and patterns are sufficient to identify patients with EoE using histologic findings as a reference.

Esophageal Mucosal Impedance Pattern is Distinct in Patients With Extraesophageal Reflux Symptoms and Pathologic Acid Reflux.

Objectives/study Design: Current diagnostic tests for gastroesophageal reflux disease (GERD) do not consistently measure chronicity of reflux. Mucosal impedance (MI) is a minimally invasive measurement to assess esophageal conductivity changes due to GERD. We aimed to investigate MI pattern in patients with symptoms of extraesophageal reflux (EER) in a prospective longitudinal cohort study.
