Objective To compare effectiveness between laparoscopic Heller myotomy and peroral endoscopic myotomy (POEM) in treatment of achalasia of cardia (AC) in order to provide a basis for clinical choose. Method The literatures about the treatment of AC by laparoscopic Heller myotomy or POEM were retrieved from CNKI, Embase, PubMed databases, etc., and then the contents about curative effect and complications were summarized. Results The treatment models of AC included surgical treatment such as laparoscopic Heller myotomy and endoscopy such as POEM, but there was still lack of comparing data in these two treatment models, its selection remained controversial. There was a better short-term curative effect and slighter complications for POEM as compared with the laparoscopic Heller myotomy from the trend of published literatures. However, it’s long-term effects for these two treatment models were not clarified. Conclusions Both laparoscopic Heller myotomy and POEM are medicable for AC. POEM as a new treatment of AC shows some advantages of minimal invasion and exact efficacy, but it needs to be followed-up for a long-term. Treatment model for AC is chosen on basis of typing under endoscope, physical fitness, anatomy of easophagus, previous history, tolerance of surgery and other factors.
Objective To determine the effectiveness and safety of pneumatic balloon dilatation in patients with achalasia. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, issue 1, 2007), MEDLINE or PUBMED (1978-2007), Embase (1978-2007), OVID Database (1978-2007), Chinese Biological Medicine Database (CBMDisc, 1978-2007), CNKI (1979-2007), Chinese VIP Database (1989-2007) and Wanfang Database (1978-2007). We also checked the reference lists of retrieved articles and relevant proceedings. We used the methods recommended by The Cochrane Collaboration to conduct this systematic review. Results Twenty four trials involving 1045 patients were included. Meta-analyses showed that the short-term total effective rate was much higher with pneumatic dilatation than intrasphincteric botulinum toxin injection (P=0.0007). The long-term total effective rate was higher with pneumatic dilatation compared to intrasphincteric botulinum toxin injection (P=0.005). Intrasphincteric botulinum toxin injection was superior to pneumatic dilatation in terms of clinical relapse rate (Plt;0.0001). Our analyses of complications and adverse effects found that pneumatic dilatation was superior to intrasphincteric botulinum toxin injection (P=0.0008), and endoscopic sphincterotomy was superior to balloon dilatation (P=0.0006). Conclusions The limited current evidence shows that: pneumatic dilatation is safe and effective for the short- or long-term treatment of achalasia.
Objective To investigate short-term outcomes of robot-assisted Heller-Dor myotomy (RAHM-Dor) for achalasia of cardia and our learning curve experience. Methods The clinical data and recent follow-up results of 42 patients who received RAHM-Dor from November 2015 to January 2020 in the Department of Thoracic Surgery of the First Affiliated Hospital of Nanchang University were retrospectively analyzed, including 20 males and 22 females with a mean age of 40.8±18.4 years. ResultsDysphagia was the most common symptom, followed by heartburn and regurgitation. The mean operation time was 122.8±23.9 min. The mean blood loss was 47.5±32.7 mL. Two patients suffered mucosal injury, and successfully repaired by suturing during surgery. There was no esophageal fistula, conversion to an open operation or perioperative death in this series. The median length of hospital stay was 8 (6, 9) d. In all patients, the Stooler and Eckardt scores of postoperative 1, 6 and 12 months decreased compared to those of pre-operation (P<0.001). Conclusion RAHM-Dor is a safe and feasible avenue for the treatment of achalasia of cardia, and can achieve a satisfying short-term results. The learning curve shows a transition to the standard stage from the learning stage after 16-18 operations.
Objective Through the methods of evidence-based medicine, to make an individualized treatment plan for a patient with achalasia. Methods Based on an adequate assessment of the patient’s condition, clinical issues aimed at this case were put forward. And the best clinical evidence related to achalasia treatment was evaluated after being retrieved from The Cochrane library (1990 to 2010) and PubMed (1980 to 2010). Results 33 studies were retrieved including 29 RCTs and 4 systematic reviews. The efficacy and safety of drug therapy, endoscopic injection of botulinum, endoscopic balloon dilatation and surgical therapy were evaluated. Cosidering symptoms,age and comorbidities, we recommended endoscopic balloon dilatation or laparoscopic Heller postoperative plus Dor fundoplication surgery for treatment. The patient’s choice is endoscopic balloon dilatation. Symptoms of patient were relieved after treatment. Conclusion Making a rational therapeutic plan for achalasia patients by means of evidence-based treatment not only can improve therapeutic effect but also be beneficial for both doctors and patients to share uncertain risks.
Objective Through a retrospective study on esophageal function changes and symptom relief after video-assisted thoracoscopic surgery treatment for achalasia of cardia (AC) to assess the clinical value of this operation. Methods We reviewed the data of 34 AC patients who received modified Heller operation by video-assisted thoracoscopic surgery in the Affiliated Hospital of Guizhou Medical University from March 2012 to September 2014. There were 11 males and 23 females with a median age of 35 (11–67) years. These patients were divided into four groups according to the time of treatment and follow-up: preoperative group, postoperative one-month group, postoperative three-month group and postoperative six-month group. Changes of symptoms, radiography and esophageal dynamics before and after therapy were collected. These different groups were analyzed based on statistical methods. Results There was no statistical difference in ages and genders among groups (P>0.05). The surgery was successful and no complication or death occurred. Symptoms of patients showed different degrees of relief and the postoperative grade of clinical symptoms decreased (P<0.05). After surgery, lower esophageal sphincter pressure (LESP), lower esophageal sphincter resting pressure (LESRP) and esophageal body pressure (EBP) decreased significantly, while lower esophageal sphincter relax rate (LESRR) increased (P<0.05). While there was no significant difference in length of lower esophageal sphincter (LESL,P>0.05). Angiography of upper digestive tract revealed that compared to the preoperative group, the maximum width in postoperative three-month group decreased significantly (P<0.05). During the follow-up, 3 patients suffered gastroesophageal reflux, 2 patients esophageal perforation and 1 patient empyema due to esophago-pleural fistula. No massive hemorrhage of upper digestive tract and hiatal hernia occured. Conclusion Sugery can significantly ameliorate the clinical symptoms of the patients with AC, and improve esophageal dynamics. And it is simple and easy to perform with less complications and better long-term outcomes. Improved Heller operation by video-assisted thoracoscopy is a less invasive procedure when compared with the traditional thoracotomy. Moreover, esophageal manometry can objectively assist in the diagnosis and degree of the disease and effect of therapy.
Background Though nitrates have been used in achalasia for a long time, the effectiveness of nitrates for achalasia is still controversial. Objectives To quantify short-term and long-term effects of nitrate therapy in patients with achalasia. Search strategy Trials were identified by searching the Cochrane Controlled Trials Register (Issue 4, 2001), MEDLINE (1966-2001), EMBASE (1980-2001), LILACS-Latin American and Caribbean health science literature (1982-2001) and CBM-Chinese Biomedical Database (1980-2000). Additionally, all references in the identified trials were checked for further relevant trials. Selection criteria All randomised controlled trials involving achalasia patients given any type of nitrates were included. Data collection amp; analysis Data were extracted By two independent observers based on the intention-to-treat principle. Odds ratios for the patients need to treat by invasive procedures, improvement of symptoms, LES pressure decrease, oesophageal emptying, and side effects were calculated. Numbers needed to treat (NNT) for avoiding invasive procedure, improvement of symptoms, oesophageal emptying, and numbers needed to harm (NNH) of side effects were also determined. Main results Two randomised cross-over studies were found, But no results are included. Due to the design of the studies and the method of reporting the results in the original paper it was not possible to extract the necessary information to examine any of the outcomes. Authors have been contacted to obtain this information. Reviewers’ conclusion We can conclude no implications for practice at this stage. Much more RCT data are needed to determine the effects of nitrates.
Mini-invasive video-assisted thoracoscopic surgery (VATS) has been employed in diagnosis and treatment of esophageal diseases for about 10 years. The potential advantages of VATS over thoracotomy are reduction of chest pain just after the operation and in the long run, lower incidence of postoperative respiratory complications, and reduction of aesthetic sequelae. Thoracoscopic staging of esophageal cancer is to evaluate the invasion and metastasis of cancer, which is helpful for better selection of patients for appropriate treatment .Operation of esophageal cancer with VATS is prescribed mainly in the early stage of carcinoma, but it’s application is restricted due to the multiple sites of operation and complexity of procedures. VATS for benign esophageal diseases such as esophageal leiomyoma and achalasia is becoming the preferable choice of operation in qualified medical centers.
