Two-Person Technique of Peroral Endoscopic Myotomy for Achalasia with an Advanced Endoscopist and a Thoracic Surgeon: Initial Experience

Achalasia

Approaches to achalasia include non-operative and operative techniques with Heller Myotomy and Per-Oral Endoscopic Myotomy (POEM) at the forefront of palliative strategies. Given the diverse subtypes and the time-dependent failure pattern for achalasia, there is no standard approach. We elect for a POEM for type III achalasia, poor functional status, hostile abdomen, and salvage after the previous myotomy. A Heller myotomy is elected over a POEM for type II achalasia, presence of diverticulum, and hiatal hernia. As long-term outcomes become available, an optimal customized strategy will become clearer.

One- or two-operator techniques for oesophago-gastro-duodenoscopy in unsedated patients: A comparative prospective randomized study

BACKGROUND

The standard oesophago-gastro-duodenoscopy procedure is performed with a single endoscopist (SE). Nurse-assisted (NA) oesophago-gastro-duodenoscopies have not yet been studied. We aimed to evaluate the efficacy of an NA endoscopy compared to an SE endoscopy.

METHODS

A prospective, single-center, randomized trial, in which 500 adult patients were divided into two groups. In the first group, patients underwent an endoscopy with an SE. In the second group, the endoscopy was performed with an NA. The ease of the procedure (scores 1-4; 1 difficult, 2 satisfactory, 3 easy, 4 veryeasy), evaluation of patient satisfaction (scores 1-4; 1 uncomfortable, 2 satisfactory, 3 comfortable, 4 verycomfortable), total time of the procedure and vocal cord observation were determined as quality indicators.

RESULTS

Mean patient satisfaction scores in groups 1 and 2 were 2.98±0.79 and 3.11±0.78, respectively (p=0.043), with uncomfortable ratings in 5.2% vs 4%, satisfactory in 16.8% vs 13.2%, comfortable in 53.2% vs 50.4%, and very comfortable in 24.8% vs 32.4% of patients in groups 1 and 2, respectively. Retching rates during the procedure were 54.4% and 45.2% (p=0.040) in groups 1 and 2, respectively. No differences were seen in vocal cord observation (54.4% vs 56.0%), total procedure time (2.35±1.56 vs 2.41±1.48min) and easy score (3.26±0.603 vs 3.25±0.64) in groups 1 and 2 for the procedures. Very easy, easy, satisfactory, and difficult ratings were given by 33.6% vs 34.8%, 60.4% vs 56.4%, 4.8% vs 7.6% and 1.2% vs 1.2% of groups 1 and 2, respectively.

CONCLUSIONS

Compared with the conventional method, the assisted endoscopic technique provides more comfort and less gag reflex without increasing the processing time or difficulty of performing the procedure.
