Endoscopic treatment of gastroesophageal reflux disease.

The endoscopic treatment of gastroesophageal reflux disease (GERD) has evolved significantly in the past 20 years. Current practices include devices specifically designed for GERD. Newer techniques aim to use less extra equipment, to be less costly, and to use accessories readily available in endoscopy units, as well as using standard endoscopes to apply such techniques. It is of utmost importance to properly select the patients for endoscopic therapy, and it should be done in a multidisciplinary approach.

El tratamiento endoscópico de la enfermedad por reflujo gastroesofágico (ERGE) ha evolucionado significativamente en los últimos 20 años. Las prácticas actuales incluyen dispositivos diseñados específicamente para la ERGE. Las técnicas más nuevas tienen como objetivo utilizar menos equipos adicionales, ser menos costosos y utilizar accesorios fácilmente disponibles en las unidades de endoscopia, así como utilizar endoscopios estándar para aplicar dichas técnicas. Es de suma importancia seleccionar adecuadamente a los pacientes para la terapia endoscópica, y debe hacerse en un enfoque multidisciplinario.

[Analysis of weight loss, metabolism, and anti-reflux effect of sleeve gastrectomy combined with fundoplication as treatment of obesity complicated by gastroesophageal reflux disease].

Objective: To explore the weight-loss, metabolism, and anti-reflux effect of laparoscopic sleeve gastrectomy combined with fundoplication (SGFD) as treatment of obesity complicated by gastroesophageal reflux disease (GERD) with the aim of identifying the best treatment for such patients. Methods: This was a retrospective cohort study. Relevant clinical data of 140 patients with obesity (body mass index≥30 kg/m2) complicated by GERD (confirmed by preoperative GerdQ score, gastroscope, upper gastrointestinal radiography, 24-hour pH monitoring of esophagus, and high-resolution esophageal manometry) who had undergone bariatric surgery in the Minimally Invasive Surgery, Hernia and Abdominal Surgery Department of the People's Hospital of Xinjiang Uygur Autonomous Region from January 2019 to February 2023 were collected. The participants were allocated to the following groups according to surgical procedure performed: sleeve gastrectomy group (SG group, 92 cases) versus SGFD (SGFD group, 48 cases). SGFD, a new type of anti-reflux weight loss surgery that achieves both anti-reflux and weight loss effects by a procedure involving "cutting first and then folding", was developed by our team. In this study, our main aim was to compare and analyze differences in outcomes between the SG and SGFD groups in terms of weight loss and improvements in metabolism and reflux 3 and 6 months postoperatively. Results: The 140 patients comprised 50 men and 90 women of average age 36.0±9.6 years and preoperative body mass index (BMI) (38.5±6.5) kg/m2. The average preoperative GERD score was 10.2±1.6. There were no significant differences in baseline characteristics between the SGFD and SG groups (all P>0.05). There were also no significant differences in postoperative hospital stay, intraoperative blood loss, or postoperative complications between the two groups (all P>0.05). However, the operation time was longer in the SGFD than SG group (137.5±10.5 minutes vs. 105.3±12.6 minutes, t=-15.131, P<0.001). Compared with preoperative values, fasting blood glucose, cholesterol, body mass, BMI, and GERD score were all lower 3 months postoperatively (all P<0.05). Six months postoperatively, triglyceride, uric acid, and DeMeester score were lower in the SGFD than SG group; however, the lower esophageal sphincter resting pressure was higher in the SGFD group (all P<0.05). There were no significant differences in weight loss indexes (body mass, BMI, percentage of excess body mass loss) or metabolic indexes (fasting blood glucose, triglyceride, cholesterol, and uric acid concentrations) between the SG and SGFD groups 3 and 6 months postoperatively (all P>0.05). However, anti-reflux indexes (GerdQ score, DeMeester score, and lower esophageal sphincter resting pressure) were all significantly better in the SGFD than SG group 6 months postoperatively (all P<0.05). Conclusion: Obese patients with GERD get good weight loss, metabolism improvement and anti-reflux effect after SGFD. SGFD is a safe and feasible surgical method, and its anti-reflux effect is better than SG at the 6th month after operation, so it is feasible.

Functional results after hiatal repair and gastropexy without fundoplication in patients with paraoesophageal hernia.

PURPOSE: Paraoesophageal hernias (PEH) are associated with a high complication rate and often occur in elderly and fragile patients. Surgical gastropexy without fundoplication is an accepted alternative procedure; however, outcomes and functional results are rarely described. Our study aims to evaluate short-term outcomes and the long-term quality of life after gastropexy as treatment for PEH. METHODS: Single center cohort analysis of all consecutive patients who underwent gastropexy for PEH without fundoplication. Postoperative outcomes and functional results were retrospectively collected. Reflux symptoms developed postoperatively were reported using the validated quality of life questionnaire: GERD-Health Related Quality of Life Qestionnaire (GERD-HRQL). RESULTS: Thirty patients (median age: 72 years (65-80)) were included, 40% classified as ASA III. Main PEH symptoms were reflux (63%), abdominal/thoracic pain (47%), pyrosis (33%), anorexia (30%), and food blockage (26%). Twenty-six laparoscopies were performed (86%). Major complications (III-IVb) occurred in 9 patients (30%). Seven patients (23%) had PEH recurrence, all re-operated, performing a new gastropexy. Median follow-up was 38 (17-50) months. Twenty-two patients (75%) reported symptoms resolution with median GERD-HRQL scale of 4 (1-6). 72% (n = 21) reported operation satisfaction. GERD-HRQL was comparable between patients who were re-operated for recurrence and others: 5 (2-19) versus 3 (0-6), p = 0.100. CONCLUSION: Gastropexy without fundoplication was performed by laparoscopy in most cases with acceptable complications rates. Two-thirds of patients reported symptoms resolution, and long-term quality-of-live associated to reflux symptoms is good. Although the rate of PEH recurrence requiring a new re-intervention remained increased (23%), it does not seem to affect long-term functional results.

Gastrointestinal Conditions: Gastroesophageal Reflux Disease.

Gastroesophageal reflux disease (GERD) affects more than 20% of adults. Risk factors include older age, obesity, smoking, and sedentary lifestyle. Lower esophageal sphincter (LES) dysfunction is a primary cause. Classic symptoms include heartburn and regurgitation. With classic symptoms, proton pump inhibitors (PPIs) can be prescribed without further testing; PPIs should be taken on an empty stomach. Patients with atypical symptoms and those not benefiting from management should undergo esophagogastroduodenoscopy (EGD), and potentially pH and impedance testing to confirm GERD or identify other conditions. This is important because GERD increases risk of esophageal erosions/stricture, Barrett esophagus, and esophageal adenocarcinoma. However, a large percentage of adults taking PPIs have no clear indication for treatment, and PPIs and other antisecretory therapy should be tapered off if possible. Of note, vonoprazan, a new drug approved by the Food and Drug Administration (FDA), has shown superiority to PPIs. In addition to pharmacotherapy, lifestyle changes are indicated, including losing weight if overweight, not lying down after meals, and ceasing tobacco use. Procedural interventions, including fundoplication and magnetic sphincter augmentation, can be considered for patients wishing to discontinue drugs or with symptoms unresponsive to PPIs. Procedural interventions are effective for the first 1 to 3 years, but effectiveness decreases over time.

Repair of type II paraesophageal hernia with Nissen fundoplication in a patient with von Willebrand disease and spondylolisthesis - a clinical case report.

Hiatal hernias continue to be fairly common in clinical practice. However, the variety of different symptoms presented by patients may hinder establishing the ultimate diagnosis. Nevertheless, currently, the diagnosis of hiatal hernia can be easily established, based on barium swallow radiography. We would like to present a clinical case report of a patient with complex medical history, including von Willebrand disease, degenerative spinal disease, and chronic sinusitis, who was finally diagnosed with hiatal hernia and treated with a standard laparoscopic Nissen fundoplication. Our case focuses on the significance of comorbidities on patients' symptoms, which sometimes may mislead the therapeutic process.

Management of Paraesophageal Hernias.

Paraesophageal hernias are classified according to the altered anatomic relationships between the gastroesophageal junction or stomach and the diaphragmatic hiatus. Herniation of these structures into the mediastinum may produce common complaints such as reflux, chest pain, and dysphagia. The elective repair of these hernias is well tolerated and significantly improves quality of life among patients with symptomatic disease. The hallmarks of a quality repair include the circumferential mobilization of the esophagus to generate 3 cm of tension-free intra-abdominal length and the performance of a fundoplication.

Pediatric nutritional surgery and its implications: results from a unicentric retrospective analysis.

PURPOSE: Existing guidelines provide weak recommendations on the surgical management of nutritional problems in children. The objective was to design a management pathway to address the best nutritional surgery (NS) procedure in a given patient. METHODS: Retrospective analysis of children treated at our department from January 2015 to December 2019. The sample was divided into two groups according to presence or absence of neurological impairment (NI). Patients with NI (Group 1) were classified in three subgroups based on presenting symptoms: A-Dysphagia without gastroesophageal reflux (GER); B-GER with or without dysphagia; C-Symptoms associated with a delayed gastric emptying. RESULTS: A total of 154 patients were included, 111 with NI. One-hundred-twenty-eight patients underwent only one procedure. Complications and mortality were superior in Group 1. In subgroup A, isolated gastrostomy was the first NS in all patients. In subgroup B most of patients were subjected to a Nissen fundoplication, while in 5 cases total esophagogastric dissociation (TEGD) was the first intervention. Considering the entire sample, 92.3% patients who underwent a TEGD did not require further procedures. CONCLUSION: NS encompasses various procedures depending on presenting symptoms and neurological status. A management flowchart for these patients is proposed.

Lessons learned from revision procedures: a case series pleading for reinforcement of the anterior hiatus in recurrent hiatal hernia.

BACKGROUND: Hiatal Hernia (HH) is a common structural defect of the diaphragm. Laparoscopic repair with suturing of the hiatal pillars followed by fundoplication has become standard practice. In an attempt to lower HH recurrence rates, mesh reinforcement, commonly located at the posterior site of the esophageal hiatus, has been used. However, effectiveness of posterior mesh augmentation is still up to debate. There is a lack of understanding of the mechanism of recurrence requiring further investigation. We investigated the anatomic location of HH recurrences in an attempt to assess why HH recurrence rates remain high despite various attempts with mesh reinforcement. METHODS: A retrospective case series of prospectively collected data from patients with hiatal hernia repair between 2012 and 2020 was performed. In total, 54 patients with a recurrent hiatal hernia operation were included in the study. Video clips from the revision procedure were analyzed by a surgical registrar and senior surgeon to assess the anatomic location of recurrent HH. For the assessment, the esophageal hiatus was divided into four equal quadrants. Additionally, patient demographics, hiatal hernia characteristics, and operation details were collected and analyzed. RESULTS: 54 patients were included. The median time between primary repair and revision procedure was 25 months (IQR 13-95, range 0-250). The left-anterior quadrant was involved in 43 patients (80%), the right-anterior quadrant in 21 patients (39%), the left-posterior quadrant in 21 patients (39%), and the right-posterior quadrant in 10 patients (19%). CONCLUSION: In this study, hiatal hernia recurrences occured most commonly at the left-anterior quadrant of the hiatus, however, posterior recurrences were not uncommon. Based on our results, we hypothesize that both posterior and anterior hiatal reinforcement might be a suitable solution to lower the recurrence rate of hiatal hernia. A randomized controlled trial using a circular, bio-absorbable mesh has been initiated to test our hypothesis.

Efficacy and safety of endoscopic cardia peripheral tissue scar formation (ECSF) for the treatment of refractory gastroesophageal reflux disease: A systematic review with meta-analysis.

BACKGROUND: Endoscopic treatment is increasingly used for refractory gastroesophageal reflux disease (rGERD). Unlike the mechanism of conventional surgical fundoplication, gastroesophageal junction ligation, anti-reflux mucosal intervention, and radiofrequency ablation have extremely similar anti-reflux mechanisms; hence, we collectively refer to them as endoscopic cardia peripheral tissue scar formation (ECSF). We conducted a systematic review and meta-analysis to assess the safety and efficacy of ECSF in treating rGERD. METHODS: We performed a comprehensive search of several databases, including PubMed, Embase, Medline, China Knowledge Network, and Wanfang, to ensure a systematic approach for data collection between January 2011 and July 2023. Forest plots were used to summarize and combine the GERD-health-related quality of life (HRQL), gastroesophageal reflux questionnaire score, and DeMeester scores, acid exposure time, lower esophageal sphincter pressure, esophagitis, proton pump inhibitors use, and patient satisfaction. RESULTS: This study comprised 37 studies, including 1732 patients. After ECSF, significant improvement in gastroesophageal reflux disease health-related quality of life score (mean difference [MD] = 18.27 95% CI: 14.81-21.74), gastroesophageal reflux questionnaire score (MD = 4.85 95% CI: 3.96-5.75), DeMeester score (MD = 42.34, 95% CI: 31.37-53.30), acid exposure time (MD = 7.98, 95% CI: 6.03-9.92), and lower esophageal sphincter pressure was observed (MD = -5.01, 95% CI: -8.39 to 1.62). The incidence of serious adverse effects after ECSF was 1.1% (95% CI: 0.9%-1.2%), and postoperatively, 67.4% (95% CI: 66.4%-68.2%) of patients could discontinue proton pump inhibitor-like drugs, and the treatment outcome was observed to be satisfactory in over 80% of the patients. Subgroup analyses of the various procedures showed that all 3 types improved several objective or subjective patient indicators. CONCLUSIONS: Based on the current meta-analysis, we conclude that rGERD can be safely and effectively treated with ECSF as an endoscopic procedure.

Enhanced recovery after surgery may mitigate the risks associated with robotic-assisted fundoplication in lung transplant patients.

INTRODUCTION: A history of lung transplantation is a risk factor for poor outcomes in patients undergoing laparoscopic fundoplication. We wanted to determine whether enhanced recovery after a robotic-assisted surgery program would mitigate these risks. METHODS: We performed a single-center retrospective analysis of the Society of Thoracic Surgery database for patients who underwent elective antireflux procedures from 1/2018 to 2/2021 under the enhanced recovery after surgery program using robotic assistance. We identified the patient and surgical characteristics, morbidity, length of stay, and 30-day readmission rates. RESULTS: Among 386 patients who underwent barrier creation, 41 had previously undergone a lung transplant, either bilateral (n = 28) or single (n = 13). There were no significant differences in postoperative complications (9.8% vs. 5.2%, p = 0.27), median hospital length of stay (1 d vs. 1 d, p = 0.28), or 30-day readmission (7.3% vs. 4.9%, p = 0.46). Bivariate analysis showed that older age (p = 0.03), history of DVT/PE (p < 0.001), history of cerebrovascular events (p = 0.03), opioid dependence (p = 0.02), neurocognitive dysfunction (p < 0.001), and dependent functional status (p = 0.02) were associated with postoperative complications. However, lung transplantation was not associated with an increased risk of postoperative complications (p = 0.28). DISCUSSION: The risk of surgical complications in patients with a history of lung transplantation may be mitigated by the combination of ERAS and minimally invasive surgery such as robot-assisted surgery.

Perioperative outcomes of the surgical management of achalasia in two tertiary Cameroonian hospitals: a cohort study.

INTRODUCTION: Achalasia is a rare esophageal disease with potentially lethal complications. Knowledge of the outcomes of the different surgical treatment modalities for achalasia by Heller's cardiomyotomy (HCM) helps to choose the safest and most effective option. However, data on the management of achalsia using a Heller myotomy is limited in Africa. Thus, our aim was to determine the perioperative morbidity, mortality and short-term functional outcomes of HCM in Cameroon. METHODOLOGY: We conducted a cohort study throughout a 10-year chart review of patients who underwent HCM for achalasia and were followed up postoperatively for at least three months at two tertiary health centers in Cameroon. We analyzed demographic data, preoperative clinical and imaging data, treatment details, and outcomes at three to twelve months after HCM using the Eckardt score. RESULTS: We enrolled 29 patients with achalasia having a mean age of 24 ± 16 years and predominantly females (M/F of 1/3.8). The mean symptom duration was 51 ± 20 months. In 80% of cases, the diagnosis was made through a conventional x-ray contrast imaging or "barium swallow test" (93%) and/or an upper gastrointestinal endoscopy (86%). The gold standard diagnostic method via esophageal manometry was unavailable. Preoperatievly, all patients had symptoms suggestive of an active achalasia. HCM was performed via laparotomy in 75% as opposed to 25% laparoscopic HCM procedures. Dor's anterior partial fundoplication was the main anti-reflux procedure performed (59%). Mucosal perforations were the only intraoperative complications in eight patients (2 during laparoscopy vs. 6 during laparotomy; p > 0.5) and were managed successfully by simple sutures. Postoperative complications were non-severe and occurred in 10% of patients all operated via laparotomy. The mean postoperative length of hospital stay was 7 ± 3 days for laparotomy vs. 5 ± 2 days for laparoscopy; p > 0.5. The perioperative mortality rate was nil. Overall, the short-term postoperative functional outcome was rated excellent; average Eckardt score of 1.5 ± 0.5 (vs. preoperative Eckardt Score of 9 ± 1; p < 0.0001). CONCLUSION: Achalasia is diagnosed late in this resource-limited setting. HCM yields satisfactory outcomes, especially via laparoscopic management. An improvement in diagnostic esophageal manometry and mini-invasive surgical infrastructure and the required surgical training/skills are needed for optimal achalasia care.

A systematic review of Sandifer syndrome in children with severe gastroesophageal reflux.

PURPOSE: Sandifer syndrome (SS), which combines gastroesophageal reflux (GER) and a neurological or psychiatric disorder, is an uncommon condition that often takes a long time to diagnosis. We aimed to systematically review available papers regarding SS. METHODS: After presenting our two cases of SS, we systematically reviewed articles published in MEDILINE/PubMed, Cochrane Library, and Web of Science. RESULTS: The meta-analysis included 54 reported cases and 2 of our own cases. Our results showed that all cases achieved symptom improvement with appropriate treatment for GER. Notably, 19 of the 56 cases exhibited anatomical anomalies, such as hiatal hernia and malrotation. Significantly more patients with than without anatomical anomalies required surgery (p < 0.001). However, 23 of the 29 patients without anatomical anomalies (79%) achieved symptom improvement without surgery. Patients who did not undergo surgery had a median (interquartile range) duration to symptom resolution of 1 (1-1) month. CONCLUSION: The primary care providers should keep SS in the differential diagnosis of patients presenting with abnormal posturing and no apparent neuromuscular disorders. Fundoplication may be effective especially for patients with anatomical anomalies or those whose symptoms do not improve after more than 1 month with nonsurgical treatment.

A Three-Arm Randomized Controlled Trial of Primary One-Anastomosis Gastric Bypass: With FundoRing or Nissen Fundoplications vs. without Fundoplication for the Treatment of Obesity and Gastroesophageal Reflux Disease.

Background and Objectives: Obesity and gastroesophageal reflux disease (GERD) are steadily increasing world weight and antireflux surgery must be performed simultaneously with bariatric surgery in obese patients. The purpose of this study is to compare bariatric and antireflux results after OAGB with different methods of fundoplication using the excluded stomach and without fundoplication. Materials and methods: This open-label, randomized, parallel three-arm trial was conducted from March 2019 and December 2021. All patients underwent laparoscopic one-anastomosis gastric bypass and suture cruroplasty, and then had a follow-up at 24 months. Group 1 of patients had fundoplication FundoRing using the excluded stomach (FundoRingOAGB); Group 2, with Nissen fundoplication using the excluded stomach (NissenOAGB); and Group 3, without fundoplication (OAGB). We studied changes in BMI, GERD symptoms (GERD-HRQL), and the VISICK score. Results: Of 219 participants screened, 150 were randomly allocated to 3 groups: FundoRingOAGB group (n = 50), NissenOAGB group (n = 50), and OAGB group (n = 50). At post-treatment month 24, BMI changes were as follows: from 40.7 ± 5.9 (31-53) to 24.3 ± 2.8 (19-29) kg/m2 in FundoRingOAGB group; from 39.9 ± 5.3 (32-54) to 26.3 ± 2.9 (23-32) kg/m2 in Nissen group; and from 40.9 ± 6.2 (32-56) to 28.5 ± 3.9 (25-34) kg/m2 in OAGB group. The mean pre-operative GERD-HRQL heartburn score improved post-op in FundoRingOAGB group from 20.6 ± 2.24 (19.96, 21.23) to 0.44 ± 0.73 (0.23, 0,64); in NissenOAGB group from 21.34 ± 2.43 (20.64, 22.03) to 1.14 ± 1.4 (0.74, 1.53); and in OAGB group 20.5 ± 2.17 (19.9, 21.25) to 2.12 ± 1.36 (1.73, 2.5). GERD-HRQL total scores were from pre-op 25.2 ± 2.7 (24.4, 25.9) to 4.34 ± 1.3 (3.96, 4.7) post-op in FundoRingOAGB group; 24.8 ± 2.93 (24, 25.67) pre-op to 5.42 ± 1.7 (4.9, 5.9) in the NissenOAGB group; and from 21.46 ± 2.7 (20.7, 22.2) to 7.44 ± 2.7 (6.6, 8.2) in the OAGB group. The mean VISICK score improved from 3.64 ± 0.94 (3.7, 3.9) to 1.48 ± 1.26 (1.12, 1.84) in FundoRingOAGB, from 3.42 ± 0.97 (3.1, 3,7) to 2.5 ± 1.46 (2.06, 2.9) in NissenOAGB group and from 3.38 ± 0.88 (3.1, 3,69) to 2.96 ± 1.19 (2.62, 3.2) in OAGB group. Conclusions: Antireflux and bariatric results of FundoRingOAGB are better than using the NissenOAGB method and significantly better than OAGB without the use of fundoplication.

Current Status of Anti-Reflux Surgery as a Treatment for GERD.

Anti-reflux surgery (ARS) is an efficient treatment option for gastroesophageal reflux disease (GERD). Despite growing evidence of the efficacy and safety of ARS, medications including proton pump inhibitors (PPIs) remain the most commonly administered treatments for GERD. Meanwhile, ARS can be an effective treatment option for patients who need medications continuously or for those who are refractory to PPI treatment, if proper candidates are selected. However, in practice, ARS is often regarded as a last resort for patients who are unresponsive to PPIs. Accumulating ARS-related studies indicate that surgery is equivalent to or better than medical treatment for controlling typical and atypical GERD symptoms. Furthermore, because of overall reduced medication expenses, ARS may be more cost-effective than PPI. Patients are selected for ARS based on endoscopic findings, esophageal acid exposure time, and PPI responsiveness. Although there is limited evidence, ARS may be expanded to include patients with normal acid exposure, such as those with reflux hypersensitivity. Additionally, other factors such as age, body mass index, and comorbidities are known to affect ARS outcomes; and such factors should be considered. Nissen fundoplication or partial fundoplication including Dor fundoplication and Toupet fundoplication can be chosen, depending on whether the patient prioritizes symptom improvement or minimizing postoperative symptoms such as dysphagia. Furthermore, efforts to reduce and manage postoperative complications and create awareness of the long-term efficacy and safety of the ARS are recommended, as well as adequate training programs for new surgeons.

Anti-reflux mucosectomy (ARMS) for refractory gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) is one of the most common diseases seen by gastroenterologists worldwide. A significant proportion of patients have a suboptimal response to acid inhibitors, especially proton pump inhibitors and potassium-competitive acid blockers. Due to concerns regarding the safety of long-term medication, many patients are unwilling to take lifelong medication. Endoscopic antireflux management offers a minimally invasive option for GERD patients. In recent decades, there have been several endoscopic antireflux therapies, including radiofrequency therapy, transoral fundoplication, and mucosal resection or mucosal ablation. Of these, antireflux mucosectomy (ARMS) is an effective and safe therapy for refractory GERD. This review provides an updated summary of antireflux mucosectomy.

MAGNETIC SPHINCTER AUGMENTATION DEVICE FOR GASTROESOPHAGEAL REFLUX DISEASE: EFFECTIVE, BUT POSTOPERATIVE DYSPHAGIA AND RISK OF EROSION SHOULD NOT BE UNDERESTIMATED. A SYSTEMATIC REVIEW AND META-ANALYSIS.

BACKGROUND: Magnetic ring (MSA) implantation in the esophagus is an alternative surgical procedure to fundoplication for the treatment of gastroesophageal reflux disease. AIMS: The aim of this study was to analyse the effectiveness and safety of magnetic sphincter augmentation (MSA) in patients with gastroesophageal reflux disease (GERD). METHODS: A systematic literature review of articles on MSA was performed using the Medical Literature Analysis and Retrieval System Online (Medline) database between 2008 and 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies. RESULTS: A total of 22 studies comprising 4,663 patients with MSA were analysed. Mean follow-up was 27.3 (7-108) months. The weighted pooled proportion of symptom improvement and patient satisfaction were 93% (95%CI 83-98%) and 85% (95%CI 78-90%), respectively. The mean DeMeester score (pre-MSA: 34.6 vs. post-MSA: 8.9, p=0.03) and GERD-HRQL score (pre-MSA: 25.8 vs. post-MSA: 4.4, p<0.0001) improved significantly after MSA. The proportion of patients taking proton pump inhibitor (PPIs) decreased from 92.8 to 12.4% (p<0.0001). The weighted pooled proportions of dysphagia, endoscopic dilatation and gas-related symptoms were 18, 13, and 3%, respectively. Esophageal erosion occurred in 1% of patients, but its risk significantly increased for every year of MSA use (odds ratio - OR 1.40, 95%CI 1.11-1.77, p=0.004). Device removal was needed in 4% of patients. CONCLUSIONS: Although MSA is a very effective treatment modality for GERD, postoperative dysphagia is common and the risk of esophageal erosion increases over time. Further studies are needed to determine the long-term safety of MSA placement in patients with GERD.

Prophylactic anti-reflux procedure for children undergoing laparoscopic gastrostomy: Rethinking of the routine practice.

AIM: Laparoscopic gastrostomy is a frequently performed procedure in children requiring long-term enteral nutrition. The role of prophylactic anti-reflux surgery during gastrostomy placements is controversial. The current study aims to evaluate the role of prophylactic anti-reflux procedures during gastrostomy placement. METHODS: A retrospective single-center analysis of all children without reflux receiving laparoscopic gastrostomy from January 2005 through December 2021 was performed. Demographics and clinical outcomes were compared between patients receiving gastrostomy placement alone and patients receiving gastrostomy with prophylactic anti-reflux surgery. RESULTS: A total of 79 patients had a confirmed absence of reflux by a 24-h pH/impedance study before operation. Thirty-six of these patients underwent prophylactic anti-reflux surgery (PAR) while 43 received gastrostomy (PG) alone. The operative time and conversion rate were significantly higher in the PAR group (140.5 ± 67.5 vs. 80.2 ± 66.8 min, p = 0.0001 and 8.3% vs. 0%, p = 0.04). There were no major complications in either group. De novo reflux was detected in five patients (11.6%) in the PG group. None of these patients progressed to require anti-reflux surgery. CONCLUSION: The occurrence of de novo reflux after laparoscopic gastrostomy was low and could be managed without anti-reflux surgery. A routine pre-operative pH study is helpful for appropriate patient selection to avoid unnecessary anti-reflux surgery, which lengthens operative time and increases the conversion rate.
