[en] Esophageal peroral endoscopic myotomy (POEM) is the treatment of reference of major obstructive esophageal motility disorders but the detection of early complications remains challenging. Our aim was to report the radiological findings on meglumine diatrizoate esophagograms after esophageal POEM and identify variables associated with patient outcomes. The imaging and clinical files of 106 patients who underwent POEM for achalasia or other major obstructive esophageal motility disorders were retrospectively analyzed. Post POEM esophagograms were reviewed for the presence of pneumoperitoneum, pleural effusion, extraesophageal contrast leakage, and dislocated clips. Associations between length of hospital stay and radiological findings were searched for using a Cox multivariate analysis. A total of 106 patients (M/F = 56/50; mean age = 50 ± 2 [SD] years) underwent 106 POEM procedures with a meglumine diatrizoate esophagogram on postoperative day 1. Overall median hospital stay was 3 days (range 1–20 days). Pneumoperitoneum, pleural effusion, extraesophageal contrast leakage, and dislocated clips were observed in 90/106 (84.9%), 12/106 (11.3%), 4/106 (3.8%), and 0/106 (0%) patients, respectively. At multivariate analysis, pleural effusion (p = 0.005; adjusted hazard ratio [aHR] = 0.35 [95% CI 0.17–0.73]) and extraesophageal contrast leakage (p = 0.039; aHR = 0.27 [95% CI 0.08–0.94]) were associated with a prolonged hospital stay. Pneumoperitoneum was not associated with unfavorable outcome (p = 0.99). Pneumoperitoneum is a common finding after POEM and is not indicative of unfavorable patient outcome. Conversely, post POEM pleural effusion and extraesophageal contrast leakage are associated with a longer hospital stay.

[en] Positron Emission Tomography (PET) is a functional nuclear medicine imaging technique which clinical value in oncology has been demonstrated. PET indications are constantly evolving, thanks to the contribution of research. The use of PET in oncology has been the subject of recommendations according to the Standard-Options-Recommendations methodology from the Federation Nationale des Centres de Lutte Contre le Cancer in 2002, updated in 2003. However, many scientific works have been published since 2003 and new tracers have also obtained a marketing authorization in France. The objective of this work was therefore to update the recommendations established in 2003. In this context, in collaboration with the Societe francaise de medecine nucleaire, a working group was set up for the development of good clinical practice recommendations under the HAS-INCA methodological label. The present document is issued from a comprehensive review of the literature and rigorous appraisal by a panel of national experts, organ specialists, clinical oncologists, surgeons, and imaging specialists. It is intended to be used as a guide to decision-making for those oncology teams that are able to manage patients in various situations in which the AMM label is not sufficiently precise. (authors)
