Robotic surgery versus Laparoscopic surgery for anti-reflux and hiatal hernia surgery: a short-term outcomes and cost systematic literature review and meta-analysis.

PURPOSE: The objective of this study is to compare the operative time, intraoperative complications, length of stay, readmission rates, overall complications, mortality, and cost associated with Robotic Surgery (RS) and Laparascopic Surgery (LS) in anti-reflux and hiatal hernia surgery. METHODS: A comprehensive literature search was conducted using MEDLINE (via PubMed), Web of Science and Scopus databases. Studies comparing short-term outcomes and cost between RS and LS in patients with anti-reflux and hiatal hernia were included. Data on operative time, complications, length of stay, readmission rates, overall complications, mortality, and cost were extracted. Quality assessment of the included studies was performed using the MINORS scale. RESULTS: Fourteen retrospective observational studies involving a total of 555,368 participants were included in the meta-analysis. The results showed no statistically significant difference in operative time, intraoperative complications, length of stay, readmission rates, overall complications, and mortality between RS and LS. However, LS was associated with lower costs compared to RS. CONCLUSION: This systematic review and meta-analysis demonstrates that RS has non-inferior short-term outcomes in anti-reflux and hiatal hernia surgery, compared to LS. LS is more cost-effective, but RS offers potential benefits such as improved visualization and enhanced surgical techniques. Further research, including randomized controlled trials and long-term outcome studies, is needed to validate and refine these findings.

Correlation analysis between the changes in plasma ghrelin level and weight loss after sleeve gastrectomy combined with fundoplication.

BACKGROUND: Laparoscopic sleeve gastrectomy combined with fundoplication (LSGFD) can significantly control body weight and achieve effective anti-reflux effects. The aim of this study is to investigate the correlation between the alteration in Ghrelin levels and weight loss following SGFD, and to compare Ghrelin levels, weight loss and metabolic improvements between SG and SGFD, with the objective of contributing to the existing body of knowledge on SGFD technique in the management of patients with obesity and gastroesophageal reflux disease (GERD). METHODS: A retrospective analysis was conducted on the clinical data of 115 obese patients who underwent bariatric surgery between March 2023 and June 2023 at the Department of Minimally Invasivew Surgery, Hernia and Abdominal Wall Surgery, People's Hospital of Xinjiang Uygur Autonomous Region. The subjects were divided into two groups based on surgical methods: sleeve gastrectomy group (SG group, 93 cases) and sleeve gastrectomy combined with fundoplication group (SGFD group, 22 cases). Clinical data, such as ghrelin levels before and after the operation, were compared between the two groups, and the correlation between changes in ghrelin levels and weight loss effectiveness after the operation was analyzed. RESULTS: Three months after the operation, there was no significant difference in body mass, BMI, EWL%, fasting blood glucose, triglyceride, cholesterol, and uric acid levels between the SG and SGFD groups (P > 0.05). However, the SGFD group exhibited a significant decrease in body weight, BMI, and uric acid levels compared to preoperative levels (P < 0.05), while the decrease in ghrelin levels was not statistically significant (P > 0.05). Logistic regression analysis indicated that ghrelin levels three months after the operation were influential in postoperative weight loss. CONCLUSION: The reduction of plasma Ghrelin level in patients after SGFD is not as obvious as that in patients after SG, but it can make obese patients get the same good weight loss and metabolic improvement as patients after SG. Ghrelin level at the third month after operation is the influencing factor of postoperative weight loss.

[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.

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.

Impact of Age on Long-Term Outcomes of Laparoscopic Nissen Fundoplication-A Single Center Study.

Background and objectives: Gastroesophageal reflux disease (GERD) is a common disease affecting approximately 20% of the adult population. This study aimed to compare the results of laparoscopic Nissen fundoplication (LNF) in the treatment of GERD in patients of different age groups. Materials and Methods: A retrospective analysis was performed on patients who underwent LNF in one surgical department between 2014 and 2018. Patients were divided into three groups based on age: under 40 years of age, 40-65 years of age, and over 65 years of age. Results: A total of 111 patients (44.1% women) were analyzed in this study. The mean age was 50.2 ±15 years, and the mean follow-up was 50 months ± 16.6 months. Recurrence of symptoms occurred in 23%, 20%, and 23% in each age group, respectively (p = 0.13), and 85%, 89%, and 80% of patients from the respective groups reported that they would recommend the surgery to their relatives (p = 0.66). Furthermore, 83%, 92%, and 73% of patients from the respective age groups reported that they would undergo the surgery again with the knowledge they now had (p = 0.16). Conclusions: Given these results and observations, LNF has been shown to be a good method of treatment for GERD in every age group. In our study, there were no differences found in terms of satisfaction with surgery and associated recommendations between the studied age groups.

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.

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.

Tailoring the wrap: intraoperative functional lumen imaging probe (FLIP) during hiatal hernia repair.

INTRODUCTION: The introduction of the functional lumen imaging probe (FLIP) has provided objective, real-time feedback on the geometric variations with each component of a hiatal hernia repair (HHR). The utility of this technology in altering intraoperative decision-making has been scarcely reported. Herein, we report a single-center series of intraoperative FLIP during HHR. METHODS: A retrospective review of electronic medical records between 2020 and 2022 was conducted and all patients undergoing non-recurrent HHR with FLIP were queried. Patient and hernia characteristics, intraoperative FLIP values and changes in decision-making, as well as early post-operative outcomes were reported. Both diameter and distensibility index (DI) were measured at 40 ml and 50 ml balloon inflation after hiatal dissection, after hiatal closure, and after fundoplication when indicated. RESULTS: Thirty-three patients met inclusion criteria. Mean age was 62 ± 14 years and mean BMI was 28 ± 6 kg/m2. The majority (53%) were type I hiatal hernias. The largest drop in DI occurred after hiatal closure, with minimal change seen after fundoplication (mean DI of 4.3 ± 2. after completion of HH dissection, vs 2.7 ± 1.2 after hiatal closure and 2.3 ± 1 after fundoplication when performed). In 13 (39%) of cases, FLIP values directly impacted intraoperative decision-making. Fundoplication was deferred in 4/13 (31%) patients, the wrap was loosened in 2/13 (15%); the type of fundoplication was altered to achieve adequate anti-reflux values in 2/13 (15%) patients, and in 1/13 (3%) the wrap was tightened. CONCLUSION: FLIP measurements can be used intraoperatively to guide decision-making and alter management plan based on objective values. Long-term outcomes and further prospective studies are required to better delineate the value of this technology.

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.

Personalized anti-reflux surgery: connecting GERD phenotypes in 690 patients to outcomes.

BACKGROUND: Anti-reflux operations are effective treatments for GERD. Despite standardized surgical techniques, variability in post-operative outcomes persists. Most patients with GERD possess one or more characteristics that augment their disease and may affect post-operative outcomes-a GERD "phenotype". We sought to define these phenotypes and to compare their post-operative outcomes. METHODS: We performed a retrospective review of a prospective gastroesophageal database at our institution, selecting all patients who underwent an anti-reflux procedure for GERD. Patients were grouped into different phenotypes based on the presence of four characteristics known to play a role in GERD: hiatal or paraesophageal hernia (PEH), hypotensive LES, esophageal dysmotility, delayed gastric emptying (DGE), and obesity. Patient-reported outcomes (GERD-HRQL, dysphagia, and reflux symptom index (RSI) scores) were compared across phenotypes using the Wilcoxon rank-sum test. RESULTS: 690 patients underwent an anti-reflux procedure between 2008 and 2022. Most patients underwent a Nissen fundoplication (302, 54%), followed by a Toupet or Dor fundoplication (205, 37%). Twelve distinct phenotypes emerged. Non-obese patients with normal esophageal motility, normotensive LES, no DGE, with a PEH represented the most common phenotype (134, 24%). The phenotype with the best post-operative GERD-HRQL scores at one year was defined by obesity, hypotensive LES, and PEH, while the phenotype with the worst scores was defined by obesity, ineffective motility, and PEH (1.5 ± 2.4 vs 9.8 ± 11.4, p = 0.010). There was no statistically significant difference in GERD-HRQL, dysphagia, or RSI scores between phenotypes after five years. CONCLUSIONS: We have identified distinct phenotypes based on common GERD-associated patient characteristics. With further study these phenotypes may aid surgeons in prognosticating outcomes to individual patients considering an anti-reflux procedure.

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.

Laparoscopic heller myotomy versus peroral endoscopic myotomy for the treatment of achalasia.

PURPOSE OF REVIEW: To compare different therapeutic modalities and determine their role in the treatment of esophageal achalasia. RECENT FINDINGS: The last 3 decades have seen a significant improvement in the diagnosis and treatment of esophageal achalasia. Conventional manometry has been replaced by high-resolution manometry, which has determined a more precise classification of achalasia in three subtypes, with important treatment implications. Therapy, while still palliative, has evolved tremendously. While pneumatic dilatation was for a long time the main choice of treatment, this approach slowly changed at the beginning of the nineties when minimally invasive surgery was adopted, initially thoracoscopically and then laparoscopically with the addition of partial fundoplication. And in 2010, the first report of a new endoscopic technique - peroral endoscopic myotomy (POEM) - was published, revamping the interest in the endoscopic treatment of achalasia. SUMMARY: This review focuses particularly on the comparison of POEM and laparoscopic Heller myotomy (LHM) with partial fundoplication as primary treatment modality for esophageal achalasia. Based on the available data, we believe that LHM with partial fundoplication should be the primary treatment modality in most patients. POEM should be selected when surgical expertise is not available, for type III achalasia, for the treatment of recurrent symptoms, and for patients who had prior abdominal operations that would make LHM challenging and unsafe.

Paraesophageal hernia recurrence following repair: making the case for reoperative surgery in a propensity-matched cohort.

BACKGROUND: Paraesophageal hernia repairs (PEHRs) have high rates of radiographic recurrence, with some patients requiring repeat operation. This study characterizes patients who underwent PEHR to identify the factors associated with postoperative symptom improvement and radiographic recurrence. We furthermore use propensity score matching to compare patients undergoing initial and reoperative PEHR to identify the factors predictive of recurrence or need for reoperation. METHODS: After IRB approval, patients who underwent PEHR at a tertiary care center between January 2018 and December 2022 were identified. Patient characteristics, preoperative imaging, operative findings, and postoperative outcomes were recorded. A computational generalization of inverse propensity score weight was then used to construct populations of initial and redo PEHR patients with similar covariate distributions. RESULTS: A total of 244 patients underwent PEHR (78.7% female, mean age 65.4 ± 12.3 years). Most repairs were performed with crural closure (81.4%) and fundoplication (71.7%) with 14.2% utilizing mesh. Postoperatively, 76.5% of patients had subjective symptom improvement and of 157 patients with postoperative imaging, 52.9% had evidence of radiographic recurrence at a mean follow-up of 10.4 ± 13.6 months. Only 4.9% of patients required a redo operation. Hernia type, crural closure, fundoplication, and mesh usage were not predictors of radiographic recurrence or symptom improvement (P > 0.05). Propensity weight score analysis of 50 redo PEHRs compared to a matched cohort of 194 initial operations revealed lower rates of postoperative symptom improvement (P < 0.05) but no differences in need for revision, complication rates, ED visits, or readmissions. CONCLUSIONS: Most PEHR patients have symptomatic improvement with minimal complications and reoperations despite frequent radiographic recurrence. Hernia type, crural closure, fundoplication, and mesh usage were not significantly associated with recurrence or symptom improvement. Compared to initial PEHR, reoperative PEHRs had lower rates of symptom improvement but similar rates of recurrence, complications, and need for reoperation.

Management of symptomatic, asymptomatic, and recurrent hiatal hernia: a systematic review and meta-analysis.

BACKGROUND: The surgical management of hiatal hernia remains controversial. We aimed to compare outcomes of mesh versus no mesh and fundoplication versus no fundoplication in symptomatic patients; surgery versus observation in asymptomatic patients; and redo hernia repair versus conversion to Roux-en-Y reconstruction in recurrent hiatal hernia. METHODS: We searched PubMed, Embase, CINAHL, Cochrane Library and the ClinicalTrials.gov databases between 2000 and 2022 for randomized controlled trials (RCTs), observational studies, and case series (asymptomatic and recurrent hernias). Screening was performed by two trained independent reviewers. Pooled analyses were performed on comparative data. Risk of bias was assessed using the Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized and non-randomized studies, respectively. RESULTS: We included 45 studies from 5152 retrieved records. Only six RCTs had low risk of bias. Mesh was associated with a lower recurrence risk (RR = 0.50, 95%CI 0.28, 0.88; I2 = 57%) in observational studies but not RCTs (RR = 0.98, 95%CI 0.47, 2.02; I2 = 34%), and higher total early dysphagia based on five observational studies (RR = 1.44, 95%CI 1.10, 1.89; I2 = 40%) but was not statistically significant in RCTs (RR = 3.00, 95%CI 0.64, 14.16). There was no difference in complications, reintervention, heartburn, reflux, or quality of life. There were no appropriate studies comparing surgery to observation in asymptomatic patients. Fundoplication resulted in higher early dysphagia in both observational studies and RCTs ([RR = 2.08, 95%CI 1.16, 3.76] and [RR = 20.58, 95%CI 1.34, 316.69]) but lower reflux in RCTs (RR = 0.31, 95%CI 0.17, 0.56, I2 = 0%). Conversion to Roux-en-Y was associated with a lower reintervention risk after 30 days compared to redo surgery. CONCLUSIONS: The evidence for optimal management of symptomatic and recurrent hiatal hernia remains controversial, underpinned by studies with a high risk of bias. Shared decision making between surgeon and patient is essential for optimal outcomes.

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.
