ABSTRACT
To investigate the effectiveness and safety of diverticular peroral endoscopic myotomy (D-POEM) for mid-esophageal diverticulum. Data of consecutive patients in the prospective database with mid-esophageal diverticulum who received D-POEM in West China Hospital, Sichuan University between April 2014 to September 2019 were collected. The modified Eckardt scoring system for mid-esophageal diverticulum was used to evaluate the severity of diverticular symptoms. The effectiveness and safety of D-POEM were evaluated in terms of clinical success, technical success, complications and recurrence. A total of 7 patients with mid-esophageal diverticulum were included. Clinical and technical success was achieved in all patients with operation time of 16-70 minutes. No serious complications (2 cases with minor complications) or recurrence occurred. The follow-up time was 2-16 months. The median modified Eckardt score decreased from 3 points before operation to 0 points after operation. It is preliminarily believed that D-POEM ensures a complete septotomy between normal esophageal lumen and esophageal diverticulum. It is a safe and effective technique for mid-esophageal diverticulum. The modified Eckardt scoring system is suitable for symptom evaluation before and after treatment of mid-esophageal diverticulum.
ABSTRACT
Objective:To investigate the medium- and long-term efficacy of peroral endoscopic myotomy (POEM) for esophageal diverticulum and the risk factors for postoperative recurrence.Methods:A retrospective study was conducted on 31 cases of esophageal diverticulum who were treated by POEM in Zhongda Hospital, Southeast University from May 1st 2016 to August 1st 2019. The Eckardt score, the operative success rate, and the recurrence rate after the operation were observed and recorded. Multivariate logistic regression analysis was performed to explore the risk factors for postoperative recurrence.Results:POEM was successfully completed in all 31 patients, who were followed up for 30.6±11.1 months (20-63 months). The Eckardt score before the operation was 8.2±2.4, and was 1.4±0.7, 1.4±1.1, 1.3±1.1, and 1.3±0.9 at 1, 6, 12 and 24 months, respectively after the operation, which significantly decreased at all follow-up time points ( P<0.001). The success rates at 1, 6, 12, and 24 months after the operation were 96.8% (30/31), 90.3% (28/31), 90.3% (28/31) and 90.3% (28/31), respectively. Three patients suffered symptom relapse, with an overall recurrence rate of 9.7% (3/31). Logistic regression analysis showed that the disease duration ( P=0.038, OR=1.041, 95% CI: 1.002-1.080) and preoperative Eckardt score ( P=0.024, OR=2.299, 95% CI: 1.117-4.728) were risk factors for postoperative recurrence of POEM. Conclusion:POEM is safe and effective for esophageal diverticulum. Patients with long disease duration and high preoperative Eckardt score are associated with recurrence.
ABSTRACT
Introduction: Achalasia cardia is a primary esophageal motility disorder of an unknown etiology, characterized by abnormal peristalsis of the esophageal body and the absence of relaxation of the lower esophageal sphincter. Laparoscopic Heller cardiomyotomy is the surgical procedure of choice for achalasia cardia. Aim: The aim of the study was to the immediate safety and long-term efficacy of laparoscopic Heller’s cardiomyotomy with intraoperative endoscopy and Dor’s anterior partial fundoplication in patients with achalasia cardia. Materials and Methods: In this prospective study, laparoscopic Heller’s myotomy with intraoperative endoscopy and anterior Dor’s fundoplication were performed in all achalasia cardia patients. Patients’ demographic, clinical features such as dysphagia grade and Eckardt score, intraoperative, post-operative parameters, and response to treatment on follow-up were analyzed. Results: In 14 patients, 10 were females (71%), the mean age was 37±14.96 years. Mean pre-operative modified Takita’s dysphagia grade was 2.93±0.73. Endoscopic classic findings and barium swallow bird beak sign were diagnostic in all cases. Preoperative Eckardt score was 8.93±1.44. Eckardt score at discharge was 0.43±0.51 and at 12th month was 0.21±0.43. On analysis, there was a significant improvement in pre-operative values of modified Takita’s dysphagia grade and Eckardt score to normal values postoperatively (P < 0.0001) and the durable effect was persistently observed in 3rd and 6th, 9th, and 12th-month follow-up. Conclusion: Laparoscopic Heller’s myotomy with intraoperative endoscopy and Dor’s fundoplication are safe and effective with significant improvement in post-operative Takita’s dysphagia score and Eckardt score.
ABSTRACT
Objective To compare the advantage and disadvantage of peroral endoscopic myotomy (POEM)and pneumatic dilation(PD)for the treatment of achalasia of cardia(AC). Methods Patients with confirmed AC undergoing endoscopic therapy in Southwest Hospital, Third Military Medical University between January 2011 and September 2014 were divided into POEM treatment group(n=56)and PD treatment group(n = 30), according to the decision of the patients and their families. Postoperative improvement of clinical symptoms, changes in the maximum esophageal diameter, complications, hospital stay,and inpatient expenses were compared between the two groups. Results No significant differences were observed in general preoperative data between the two groups,including gender,age,body mass index (BMI),maximum esophageal diameter, Eckardt score and disease duration(all P>0.05). The Eckardt score showed a significant decrease in 1, 6, and 12 months after operation compared to the pre?operation score in both groups(P<0.05). No matter 1 month or 6 months after operation, the Eckardt score had no significant difference between the two groups(P>0.05). Six months after operation, the response rate between the two groups was no significantly different[93%(52/56)VS 80%(24/30), χ2=0.115, P=0.076],but the maximum esophageal diameter of the POEM group was smaller than that of the PD group (25.39±7.12 mm VS 32.12±9.99 mm,t=3.612,P=0.001). Twelve months after operation,the Eckardt score of the POEM group was lower than that of the PD group(0.44±0.85 score VS 1.26±1.74 score,t=2.940,P= 0.004), and the response rate was higher in the POEM group[93%(52/56)VS 80%(24/30),χ2=0.115, P=0.076]. The incidence of pneumatic complications was 32%(18/56)in the POEM group,but none occurred in the PD group(χ2=12.195,P=0.000). The hospital stay of the POEM group and the PD group was 12.33±4.13 days and 6.50±2.28 days, respectively(W=616, P=0.000). The inpatient expense of the POEM group and the PD group was 8 013.283± 4 322.695 yuan, and 1 571.018±1 590.193 yuan,respectively(W=505,P=0.000).Conclusion Both POEM and PD showed good short?term efficacy for AC.POEM is more effective,and its treatment outcome lasts longer,whereas PD has more widely indications because it is easier to operate with less complications,shorter hospital stay,and lower costs.Trail registration Chinese clinical trial registry,ChiCTR?OOC?15005889.
