Positive effect of erythromycin on ineffective oesophageal motility in laryngopharyngeal reflux patients: Room for a novel treatment?

Introduction: Laryngopharyngeal reflux (LPR) management guidelines are currently derived from the management of gastroesophageal reflux disease (GORD) which has been shown to be poorly effective in controlling symptoms for these patients. Erythromycin is a macrolide antibiotic that has been used extensively as a prokinetic agent for the gastrointestinal tract. The management of LPR with prokinetics is a novel therapy being investigated with regard to its effectiveness.

Solid versus liquid pulmonary micro-aspiration of reflux disease. Does it make a difference in determining the need for intervention?

Background: Pulmonary micro-aspiration (PMA) is a feared complication of gastroesophageal reflux disease (GORD). A novel scintigraphic test for GORD has been developed and validated. It can demonstrate contamination of the upper and lower airways by refluxate.

Radiologic myosteatosis predicts major complication risk following esophagectomy for cancer: a multicenter experience.

Background: Myosteatosis is a measure of skeletal muscle quality that is readily identifiable on computed tomography (CT). The effect of preoperative myosteatosis on outcomes after radical esophagectomy remains unclear. This study aimed to correlate the presence of myosteatosis on CT scan with perioperative morbidity, mortality, and survival outcomes after esophagectomy in an Australian population across 3 esophageal cancer centers.

Scintigraphic Imaging of Extra-Esophageal Manifestation of Gastresophageal Reflux Disease.

Objectives: There is currently no reference standard test for the detection of the extra-esophageal manifestations of gastroesophageal reflux disease (GERD). The current suite of diagnostic tests principally assesses reflux events in the esophagus. A new scintigraphic technique has been developed and validated against reference standards.

The influence of socioeconomic disadvantage on short- and long-term outcomes after oesophagectomy for cancer: an Australian multicentre study.

Background: Socioeconomic status (SES) affects outcomes following surgery for various cancers. There are currently no Australian studies that examine the role of socioeconomic disadvantage on outcomes following oesophagectomy for cancer. This study assessed whether SES was associated with short-term perioperative morbidity, long-term survival, and oncological outcomes following oesophagectomy across three tertiary oesophageal cancer centres in Australia.

Sarcopenia impacts perioperative and survival outcomes after esophagectomy for cancer: a multicenter study.

Background: The impact of sarcopenia on outcomes after esophagectomy is controversial. Most data are currently derived from Asian populations. This study aimed to correlate sarcopenia to short-term perioperative complication rates and long-term survival and recurrence outcomes.

Risk of lymph node metastasis in T1 esophageal adenocarcinoma: a meta-analysis.

Patients with early (T1) esophageal adenocarcinoma (EAC) are increasingly having definitive local therapy endoscopically. Endoscopic resection is not able to pathologically stage or treat lymph node metastasis (LNM). Accurate identification of patients having nodal metastasis is critical to select endoscopic therapy over surgery.

Extensive lymphadenectomy may improve survival in node negative oesophageal cancer.

Lymph node metastases are a major prognostic factor in survival of patients with oesophageal cancer. The number of lymph nodes removed during oesophagectomy has been previously proven to be associated with improved survival. The aim of this study was to examine the effect of lymph node harvest on survival specifically in pathologically node negative (pN0) patients with oesophageal cancer.

Durability of radiofrequency ablation for long-segment and ultralong-segment Barrett's esophagus over 10 years.

Background: Long-term durability data for radiofrequency ablation (RFA) to prevent esophageal adenocarcinoma in long-segment (LSBE) and ultralong-segment Barrett's esophagus (ULSBE) is lacking. This study aimed to determine 10-year cancer progression, eradication, and complication rates in LSBE and ULSBE patients treated with RFA.

Methods: Single-surgeon prospective database of patients with LSBE (≥ 3 to < 8 cm) and ULSBE (≥ 8 cm) who underwent RFA (2001-2021) were retrospectively analyzed.

Recurrence in Paraesophageal Hernia: Patient Factors and Composite Surgical Repair in 862 Cases.

Background: Repair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study analyzed a large series of laparoscopic giant PEH repair to determine factors associated with anatomical recurrence.

Method: Data was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991 to 2021.

Laparoscopic common bile duct exploration: what factors determine success?

Backgrounds: Laparoscopic common bile duct exploration (LCBDE) has been shown to be effective in managing choledocholithiasis whilst avoiding ERCP-related complications. However, patient and technical factors effects outcome. This study aimed to explore the matters effecting the failure of LCBDE.

Acute oxygen desaturation characterizes pulmonary aspiration in patients with gastroesophageal reflux disease and laryngopharyngeal reflux.

The aim of this study was to characterise pulmonary aspiration of refluxate in patients with gastroesophageal reflux disease (GORD) and laryngopharyngeal reflux (LPR) by continuous pulse oximetry (SpO2) during the supine phase of a scintigraphic reflux study. Variables assessed for significance included age, hiatus hernia, frequency, amplitude of reflux and clearance of reflux from the oesophagus/pharynx. The patients included in this study had established GORD and LPR by clinical history.

Clinicopathologic and survival differences between adenocarcinoma of the distal oesophagus and gastro-oesophageal junction.

Background: The incidence of adenocarcinoma of the distal oesophagus (DO) and gastro-oesophageal junction (GOJ) are increasing. They may represent differing disease processes. This study aimed to assess clinicopathological and survival differences between patients with DO and GOJ adenocarcinomas.

Different clinical symptom patterns in patients with reflux micro-aspiration.

Background: Pulmonary manifestation of gastro-oesophageal reflux disease (GORD) is a well-recognised entity; however, little primary reported data exists on presenting symptoms of patients in whom reflux micro-aspiration is confirmed. The aim of this study is to report symptoms and presenting patterns of a large group of patients with confirmed reflux micro-aspiration.

Patients And Methods: Data was extracted from a prospectively populated database of patients referred to a tertiary specialist centre with severe, refractory or atypical reflux.

Failed fundoplication with delayed gastric emptying: efficacy of subtotal gastrectomy.

Background: The management of patients with gastroparesis and recurrent reflux after previous fundoplication is challenging. The aim of this study was to evaluate the safety and efficacy of subtotal gastrectomy with Roux-en-Y reconstruction as a remedial procedure in this select patient population.

Method: Retrospective analysis of a prospectively populated database identified all patients that underwent subtotal gastrectomy with Roux-en-Y reconstruction (SGRNY) due to reflux symptoms and delayed gastric emptying (DGE).

Oesophageal adenocarcinoma: In the era of extended lymphadenectomy, is the value of neoadjuvant therapy being attenuated?

Background: Neoadjuvant chemotherapy (NACT) and oesophagectomy is the standard of care for resectable oesophageal adenocarcinomas. Survival outcomes following resection have been improving over time while NACT remain largely unchanged. Indeed, a recent meta-analysis of randomized control trials did not demonstrate a survival benefit in adding NACT, raising the possibility that improved surgical techniques may be reducing the perceived effectiveness of NACT.

Post-reflux swallow-induced peristaltic wave is impaired in laryngopharyngeal and gastro-oesophageal reflux disease.

Introduction: Laryngopharyngeal reflux (LPR) and gastro-oesophageal reflux disease (GORD) result from the reflux of gastric contents. The post-reflux swallow-induced peristaltic wave (PSPW) is an oesophageal reflex that facilitates chemical clearance of gastric contents following reflux events. PSPW index is a novel parameter that has been validated in assessing the effectiveness of chemical clearance in GORD, but not in LPR.

Conventional and simple methods of measuring esophageal nocturnal baseline impedance show excellent agreement.

Objectives: Mean nocturnal baseline impedance (MNBI) shows promise in investigating reflux disease by reflecting esophageal mucosal integrity. This study aimed to measure MNBI by both conventional and simple methods in patients with laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD) in order to evaluate the efficacy of the simple measurement method.

Methods: Altogether 187 patients were divided into LPR (n = 105) or GERD (n = 82) groups according to their predominant symptom profile, and underwent off-therapy impedance-pH monitoring.

Modified Reflux Scintigraphy Detects Pulmonary Microaspiration in Severe Gastro-Esophageal and Laryngopharyngeal Reflux Disease.

Introduction: Previously described methodologies for detecting laryngopharyngeal reflux (LPR) have limitations. Symptoms alone are non-diagnostic, and pH-impedance studies have poor sensitivity. Pulmonary micro-aspiration is under-recognised in LPR and gastro-esophageal reflux disease (GERD).
