Résumé
For medically refractory diabetic or idiopathic gastroparesis, gastric electrical stimulation (GES) is an excellent option for symptom control; however, a small subset of patients may develop recurrent or persistent symptoms. Per-oral pyloromyotomy (POP, also described by some authors as gastric per-oral endoscopic myotomy or G-POEM) is an emerging therapy for medically refractory gastroparesis. This study investigated the safety and feasibility of POP after previous GES for recurrent or persistent gastroparesis. We retrospectively identified all patients undergoing POP between January 2016 and December 2017, with GES in situ. Patient characteristics, gastroparesis etiology, and procedural data were collected. Symptoms were assessed with the Gastroparesis Cardinal Symptom Index (GCSI) both before and 30 to 90 days after POP. Standard pre- and post-procedure 4-hour gastric emptying tests were obtained when available. There were 22 patients who met inclusion criteria (81.8% female, mean age 42.3 ± 12.4 years). Causes of gastroparesis were diabetes in 38.1%, and idiopathic in 61.9%. The average time since GES insertion was 3.45 years. Mean preoperative 4-hour gastric retention was 50.1%. Most POP procedures were performed in the operating room (90.9%), with mean operative time of 40 minutes and a 1.4-day length of stay. There were 4 readmissions within 30 days, but no POP-related complications. Overall, GCSI improved by an absolute reduction of 1.63 points (p = 0.002), with significant improvements in all sub-scores. Of 11 patients with post-procedural motility or emptying studies available, 7 were normal. Per-oral pyloromyotomy appears to be safe and feasible for patients with recurrent gastroparesis symptoms after GES. Both symptoms and motility significantly improved in the short-term. These data replicate similar data suggesting laparoscopic pyloroplasty as an effective augmentative therapy after GES, but may provide a less invasive option for patients.

BACKGROUND
For medically refractory diabetic or idiopathic gastroparesis, gastric electrical stimulation (GES) is an excellent option for symptom control; however, a small subset of patients may develop recurrent or persistent symptoms. Per-oral pyloromyotomy (POP, also described by some authors as gastric per-oral endoscopic myotomy or G-POEM) is an emerging therapy for medically refractory gastroparesis. This study investigated the safety and feasibility of POP after previous GES for recurrent or persistent gastroparesis.
STUDY DESIGN
We retrospectively identified all patients undergoing POP between January 2016 and December 2017, with GES in situ. Patient characteristics, gastroparesis etiology, and procedural data were collected. Symptoms were assessed with the Gastroparesis Cardinal Symptom Index (GCSI) both before and 30 to 90 days after POP. Standard pre- and post-procedure 4-hour gastric emptying tests were obtained when available.
RESULTS
There were 22 patients who met inclusion criteria (81.8% female, mean age 42.3 ± 12.4 years). Causes of gastroparesis were diabetes in 38.1%, and idiopathic in 61.9%. The average time since GES insertion was 3.45 years. Mean preoperative 4-hour gastric retention was 50.1%. Most POP procedures were performed in the operating room (90.9%), with mean operative time of 40 minutes and a 1.4-day length of stay. There were 4 readmissions within 30 days, but no POP-related complications. Overall, GCSI improved by an absolute reduction of 1.63 points (p = 0.002), with significant improvements in all sub-scores. Of 11 patients with post-procedural motility or emptying studies available, 7 were normal.
CONCLUSIONS
Per-oral pyloromyotomy appears to be safe and feasible for patients with recurrent gastroparesis symptoms after GES. Both symptoms and motility significantly improved in the short-term. These data replicate similar data suggesting laparoscopic pyloroplasty as an effective augmentative therapy after GES, but may provide a less invasive option for patients.
