RESUMEN
Objective: To evaluate the safety and efficacy of domestically produced magnetic sphincter augmentation (MSA) for gastroesophageal reflux disease. Method: This study is a prospective cohort study. Patients with typical heartburn and reflux symptoms (at least partial response to proton pump inhibitors), abnormal esophageal acid exposure and normal esophageal peristalsis were included, prospectively in the Department of Gastroesophageal Surgery, Rocket Force Characteristic Medical Center from June 2019 to September 2022. Patients with hiatal hernia >2 cm and severe esophagitis were excluded. The MSA was wrapped around the distal esophagus after esophageal hiatus repair by laparoscopy. A postoperative questionnaire survey was conducted to assess the relief of symptom, complications, the discontinuation rate of proton pump inhibitor, and surgical satisfaction. Gastroscopy, high-resolution esophageal pressure measurement, and pH value impedance monitoring were also reviewed. The pre- and postoperative rates were compared using the McNeinar χ2 test. Result: Currently, 23 patients with gastroesophageal reflux disease were enrolled and underwent MSA surgery. There were 20 males and 3 females, aged (M (IQR)) 48 (14) years (range: 25 to 64 years). All cases were successfully implanted with MSA. Subjective indicators were followed for 17 (18) months (range: 14 to 53 months), while objective indicators were followed for 17 (1) months (range: 12 to 23 months). The postoperative gastrointestinal and extraesophageal symptom scores showed a significant decrease compared to preoperative levels as follows: the degree of subjective relief of overall digestive symptoms was 90 (20)% (range:0~100%), the degree of subjective relief of overall respiratory symptoms was 100(10)% (range: 10%~100%), the overall satisfaction rate was 83% (19/23), the proton pump inhibitor discontinuation rate was 70% (16/23). The proportion of esophagitis has decreased from 44% (10/23) to 9% (2/23) (κ=0.169, P=0.039), The Hill grade of gastroesophageal valve morphology improved from 1 case of grade â , 5 cases of grade â ¡, 10 cases of grade â ¢, and 7 cases of grade â ¢ preoperative to 22, 1, 0, and 0 cases postoperative. The proportion of lower esophageal sphincter pressure below normal has decreased from 70% (16/23) to 35% (8/23) (κ=0.170, P=0.012). There were 21 patients who restored normal esophageal acid exposure. Eleven patients had mild long-term dysphagia, but it didn't affect their daily life. No postoperative device migration, erosion, or secondary surgical removal occurred. Conclusions: Laparoscopic implantation of the MSA device was safe and well tolerated. It can effectively control the symptoms of gastroesophageal reflux disease, reduce medication, restore normal cardia morphology and function, and esophageal acid exposure. The main postoperative complication was dysphagia, but it was relatively mild.

Objective: To investigate the effect of a novel laparoscopic W-H fundoplication in the treatment of proton pump inhibitor (PPI) dependent gastroesophageal reflux disease (GERD). Methods: The clinical data of PPI dependent GERD patients who underwent laparoscopic W-H fundoplication in PLA Rocket Force Characteristic Medical Center from October 1st, 2018 to April 30th, 2019 were analyzed retrospectively. The GERD symptom score, subjective symptom relief, PPI withdrawal, efficacy satisfaction and postoperative complications were followed up and analyzed by a questionnaire. Results: A total of 80 GERD patients were included in this study, and 49 were male and 31 were female, with a median age of 58 years. Among all patients, 85% (68/80) are with esophagitis and 77.5% (62/80) with hiatal hernia. The operation time was 67 (52, 73) minutes, without intraoperative complications and conversion to laparotomy. The postoperative follow-up period was 16 (14, 18) months. The postoperative GERD symptom scores were significantly lower than those before surgery, with an statistical difference (all P<0.05). The subjective remission degree of the overall digestive and respiratory symptoms were 100 (90, 100)% and 100 (80, 100)%, respectively. During the follow-up period, the PPI discontinuation rate was 83% (69/80), and the satisfactory rate was 93% (75/80). Postoperative complications included dysphagia, flatulence, increased exhaust and diarrhea, and the incidence was 61% (49/80), 8% (6/80), 5% (4/80) and 4% (3/80), respectively, and 16% (13/80) of the patients had prolonged occasional mild dysphagia. There was no death, symptomatic recurrence or reoperation. Conclusions: The novel W-H fundoplication has a good medium-term efficacy, with significant GERD symptom control rate and PPI discontinuation rate. The postoperative dysphagia is common, but it is self-limiting and does not affect the satisfaction of the surgical effect.

Objective: To analyze the relationship between the severity of esophageal acid reflux and esophageal motility, esophageal mucosal injury and morphological anatomy of gastroesophageal junction (GEJ) in patients with gastroesophageal reflux disease (GERD). Methods: The clinicaldata of GERD patients who underwent 24 h pH-impedance monitoring, gastroscopy and high-resolution manometry (HRM) from January 2016 to January 2019 in the Gastroesophageal Surgery Department of PLA Rocket Force Characteristic Medical Center were retrospectively analyzed. The patients were divided into non-pathological acid reflux group, mild pathological acid reflux group and moderate to severe pathological acid reflux group according to the DeMeester score. The gender and age of each group were matched, with 60 cases in each group. Statistical analysiswas performed to analyze thedifferences in upper esophageal sphincter pressure, lower esophageal sphincter pressure (LES), LES length, length of ventral LES, percentage of ineffective swallowing, esophagitis, Hill grade of GEJ, and hiatus hernia (HH) in each group. The comparison and correlation analysis are also carried out between the groups. Results: The male-female ratio was 33/27, and the age was (57±13) years in each group. Non-parametric analysis showed that the LES pressure and the length of the ventral LES decreased with the severity of acid reflux, and there was a statistical difference (P= 0.033, P=0.015). The detection rate of HH by HRM increased significantly (χ(2)=0.001) as well. Esophagitis score increased with the severity of acid reflux and there was statistical difference (P<0.001).The detection rate of esophagitis increased significantly (χ(2)<0.001) as well. Hill grading score of GEJ increased with the severity of acid reflux, and there was statistical difference (P<0.001).The detection rate of HH by endoscopy increased significantly (χ(2)<0.001) as well. The correlation between DeMeester score and LES pressure, length of ventral LES, percentage of ineffective swallowing, esophagitis score, and Hill grade score were statistically significant (P<0.05). Conclusions: The esophageal low motility (such as low LES pressure) and anatomical abnormalities (abdominal esophageal shortening, GEJ flabbiness, and even HH formation) of the GEJ regionare significantly associated with the severity of acid reflux. These factors may be important causes of increased acid reflux. In addition, the aggravation of acid reflux can also increase the incidence and severity of esophagitis.

Objective: To analyze esophageal motility dysfunction in gastroesophageal reflux disease (GERD) with different severity of esophagitis, and the relationship between the esophageal motility dysfunction and the severity of esophagitis. Methods: GERD patients simultaneously undergone endoscopy and high-resolution manometry were divided into four groups: Non-esophagitis (Non-erosive gastroesophageal reflux disease, NERD) group, mild esophagitis group, moderate esophagitis group and severe esophagitis group. The gender and age were matched for each group, and every group consisted of 80 cases. Nonparametric test was used to analyze the differences in HRM parameters, such as upper esophageal sphincter (UES) pressure, lower esophageal sphincter (LES) pressure, LES length, LES-CD (crural diaphragm) separation distance, and the percentage of failed peristalsis of the four groups, and the differences between each two of the groups were also analyzed. Results: Nonparametric test showed that the LES pressure and length decreased with the severity of esophagitis, and there were statistical differences (P<0.001, P=0.030). The failed peristalsis percentage increased with the severity of esophagitis and the difference was statistically significant (P<0.001). The LES-CD separation distance was increased with the severity of esophagitis and had statistically significance (P<0.001). When comparing the differences between each two of the groups, there were significant differences (P<0.001, P=0.012, P<0.001, P<0.001) between NERD group and severe esophagitis group in the HRM parameters of the lower esophageal sphincter pressure, the LES length, the LES-CD separation distance, and the percentage of ineffective swallowing in the NERD and severe esophagitis group. The detection rate of HH was significantly increased from NERD to severe esophagitis, the detection rate of HH was 6.3% to 82.5% in gastoracopy and 16.3% to 45.0% in HRM, and the diagnostic consistency was fair (Kappa Value: 0.31). Conclusions: Hypo-dynamic state of esophageal and HH are the main motility characteristics of erosive gastroesophageal reflux disease, Esophageal motility abnormalities increase in parallel with the severity of GERD from NERD to severe esophagitis, these motility disorders may also play important roles in causing esophagitis.
