Spade-Shaped Anastomosis after Laparoscopic Proximal Gastrectomy Using Double Suture Anchoring between the Posterior Wall of the Esophagus and the Anterior Wall of the Stomach (SPADE Operation): A Case Series

We introduced SPADE operation, a novel anastomotic method after laparoscopic proximal gastrectomy (PG). Technical modifications were performed and settled. This report aimed to demonstrate the short-term clinical outcomes after settlement. Data from 34 consecutive patients who underwent laparoscopic PG with SPADE between June 2017 and March 2020 were retrospectively reviewed. Reflux was evaluated based on the patients’ symptoms and follow-up endoscopy using Los Angeles (LA) classification and RGB Classification (Residue, Gastritis, Bile). Other complications were classified using the Clavien–Dindo method. The incidence of reflux esophagitis was 2.9% (1/34). Bile reflux was observed in six patients (17.6%), and residual food was observed in 16 patients (47.1%) in the endoscopy. Twenty-eight patients had no reflux symptoms (82.4%), while five patients (14.7%) and one patient (2.9%) had mild and moderate reflux symptoms, respectively. The rates of anastomotic stricture and ileus were 14.7% (5/34) and 11.8% (4/34), respectively. No anastomotic leakage was observed. The incidence of major complications (Clavien-Dindo grade III or higher) was 14.7%. The SPADE operation following laparoscopic PG is effective in reducing gastroesophageal reflux. Its clinical usefulness should be validated using prospective clinical trials.

Predictors of Patient-Reported Dysphagia and Reflux Symptoms in Obstructive Sleep Apnea

Purpose: Despite the reported high prevalence of dysphagia and reflux, patients with obstructive sleep apnea (OSA) are not routinely screened for dysphagia or reflux during conventional OSA management. The purpose of this exploratory study was to (a) identify prevalences of dysphagia and reflux self-reported symptoms in patients with OSA and (b) determine associations between dysphagia and reflux symptoms and demographic and clinical variables. Method: A chart review was completed on 75 patients with treated OSA during routine medical management at a university-affiliated sleep center. All participants completed the 10-Item Eating Assessment Tool (EAT-10) and Reflux Symptom Index (RSI) questionnaires, which are patient-reported outcome measures (PROMs) of swallowing and reflux symptoms, respectively. Relevant demographic and clinical variables were extracted. A binary logistic regression was computed to examine the relationships between dysphagia and reflux PROMs and demographic and clinical variables. Result: Sixty-three participants met eligibility criteria ( M age = 64 years). In addition, 14% ( n = 9) and 11% ( n = 7) of patients with OSA syndrome reported swallowing and reflux symptoms, respectively. Among the demographic and clinical variables investigated, there were no significant predictive factors for EAT-10 scores. Age and apnea–hypopnea index were significant predictive factors for RSI scores. Conclusions: To our knowledge, this is the first preliminary study to investigate swallowing and reflux symptoms concurrently in OSA, as well as potential mitigating factors. Although our findings suggest a relatively low percentage of patients with OSA report dysphagia and reflux symptoms, the true prevalences of swallowing and reflux disorders may be higher based on previous evidence suggesting that pharyngeal afferent (sensory) dysfunction may cause patients to underestimate their symptoms.

Combination of Symptom Profile, Endoscopic Findings, and Esophageal Mucosal Histopathology Helps to Differentiate Achalasia from Refractory Gastroesophageal Reflux Disease

: Achalasia, a rare primary esophageal motility disorder, is often misdiagnosed as refractory gastroesophageal reflux disease (GERD). This study is aimed to identify the clinical and histopathologic features that may help to differentiate these two entities. Patients with untreated achalasia and those with refractory reflux symptoms despite ≥8 weeks of proton-pump inhibitor treatment were enrolled prospectively. All patients underwent validated symptom questionnaires, esophagogastroduodenoscopy with biopsy, and high-resolution impedance manometry (HRIM). Histopathology of esophageal mucosa was compared based on four pre-determined histological criteria: basal cell hyperplasia or papillae elongation, eosinophilic infiltration, petechiae formation, and hypertrophy of the muscularis mucosae (MM). Compared with the GERD patients, patients with achalasia had similar reflux symptoms, but higher Eckardt scores, fewer erosive esophagitis and hiatal hernia, more esophageal food retention on endoscopy, and higher prevalence of hypertrophy of the MM and petechiae formation on histopathology. Multivariate logistic regression based on Eckardt score ≥4, normal esophagogastric junction morphology or esophageal food retention, and coexistence of petechiae formation and hypertrophy of the MM, established the best prediction model for achalasia. Therefore, combination of routinely accessible variables, including Eckardt score, endoscopic features, and histopathology obtained via esophageal mucosal biopsy, may provide an earlier identification of achalasia.

A Novel Method of Piggyback Jejunal Interposition Reconstruction Single-Tract Reconstruction After Proximal Gastrectomy for Siewert II and III Adenocarcinoma of the Esophagogastric Junction with a Diameter <4 cm

Background Digestive tract reconstruction after proximal gastrectomy (PG) has been extensively discussed. Herein, we introduce a novel method of PG with piggyback jejunal interposition reconstruction single-tract reconstruction (PJIRSTR) for Siewert II and III adenocarcinoma of the esophagogastric junction (AEG) with a diameter <4 cm, and investigate its safety, practicability, and short-term and long-term clinical outcomes of this procedure. Method The clinical data of 33 patients with Siewert II or Siewert III AEG who underwent PJIRSTR in Shanxi Cancer Hospital from July 2013 to November 2016 were retrospectively reviewed. Data of clinicopathologic characteristics, postoperative and surgical outcomes, and follow-up findings, especially postoperative reflux esophagitis and postoperative reflux symptoms, were analyzed.Results The mean operation time was 136.7±22.4 (range: 110-180) min, including 32.3 ± 5.0(range: 26-45) min of the digestive tract reconstruction; the mean estimated blood loss was 87.6±18.1 mL; the mean number of dissected lymph nodes was 14.7±5.1; and the mean duration of postoperative hospitalization was 7.5±1.2 days. The early complication rate was 9% (n=3), including one case each of anastomotic bleeding, incision infection, and ileus. The late complication rate was 6% (n=2): both patients had gastroesophageal reflux symptoms (Visick grade II), but only one patient had Los Angeles grade B reflux esophagitis by endoscopy. Conclusion PJIRSTR is a safe, feasible, and innovative reconstruction method after PG for patients with Siewert II and III AEG with a diameter <4 cm. Furthermore, it has excellent efficiency in terms of preventing reflux symptoms and reflux esophagitis after surgery.

Impact of Gastropexy/Omentopexy on Gastrointestinal Symptoms after Laparoscopic Sleeve Gastrectomy

Background Laparoscopic sleeve gastrectomy (LSG) has become a single-step operation for the management of severe obesity. A statistically significant number of participants who undergo this procedure experience nausea, vomiting, and reflux symptoms early after the operation. The objectives of this study were to measure the positive or negative effect of gastropexy on reducing distressing postoperative LSG-related gastrointestinal symptoms. Patients and Methods This was a comparative randomized study conducted from January 2018 to January 2021. The study was carried out in the general surgery department at Menoufia University Hospital, Menoufia Faculty of Medicine in Egypt. Two hundred participants were included randomly during this trial. The participants were divided into two groups, with 100 patients in each group. Patients in group A underwent gastropexy, and patients in group B underwent LSG without gastropexy. Results There was no significant difference between the groups in age or sex (p > 0.05). There was no significant difference in the length of hospital stay (p > 0.05). There was a significant difference between the two groups regarding nausea, vomiting, reflux symptoms, and the amount and frequency of antiemetics used (p < 0.001). There was also a significant difference in hospital readmissions (p < 0.05) and in clinic visits during the postoperative period. Conclusions Patients who underwent gastropexy showed a significant reduction in antiemetic consumption and a significantly lower incidence of postoperative nausea, vomiting, gastroesophageal reflux disease symptoms and gastric torsion than those who did not undergo gastropexy.

P-O02 Management Experiences of Post-gastrectomy Severe Alkaline Reflux Oesophagitis

Background Alkaline reflux oeosphagitis is a recognized complication of procedures that compromise the lower oesophageal sphincter (LES), including gastrectomy. Incidence of reflux is dependent on the reconstructive procedure with Roux-en-Y esophagojejunostomy commonly accepted as the optimal method. The authors report their experience of 6 patients who underwent remedial intervention for severe alkaline reflux esophagitis following gastric surgery. Methods A retrospective review of 6 patients who had underwent a previous gastric procedure and developed symptoms of gastroesophageal reflux disease, over a 6-year period (2014-2020). Reflux symptoms were diagnosed by clinical history, radiology, endoscopy and esophageal manometry prior to proceeding to surgical reflux control. Post-operative outcomes following anti-reflux surgery were assessed by means of serial outpatient assessments and endoscopy. Results Six patients were included in this report, 4 males and 2 females with an average age of 73 years (range 58-91). Primary diagnoses encompassed; 4 gastric adenocarcinomas, 1 gastric neuroendocrine tumour and 1 patient with debilitating gastric antral vascular ectasia (GAVE) syndrome. Four patients underwent total gastrectomy and 2 subtotal gastrectomy with Roux-en-Y reconstruction. Onset of post-operative reflux symptoms ranged from 2-weeks to 3-years. Failing medical management, all patients underwent jejunojejunal anastomosis and Roux limb length revision with surgical jejunostomy. At follow up 5 patients had some degree of symptom resolution; 3 complete resolution, 2 initial resolution and 1 with unresolved symptoms. Conclusions Severe alkaline reflux oesophagitis is a recognized complication of gastric procedures compromising the LES. The authors report our experience of managing this complication following gastrectomy with jejunojejunal anastomosis and Roux limb length revision, with a majority of patients having improvement in if not complete resolution of reflux symptoms.

Esophageal Pressure and Clinical Assessments in the Gastroesophageal Reflux Disease Patients with Laryngopharyngeal Reflux Disease

Laryngopharyngeal reflux disease (LPRD) might be associated with reflux symptoms, and its severity is correlated with the Reflux Symptoms Index. Diagnosis is often challenging because of a lack of accurate diagnostic tools. Although an association between LPRD and gastroesophageal reflux disease (GERD) exists, the extent to which esophageal pressure changes in patients with LPRD with GERD has been unknown. Therefore, this study surveys the clinical assessments and extent of esophageal pressure changes in LRPD patients with various GERD severities, and compares esophageal sphincter pressures between ages, genders, and body mass index (BMI). This observational study assessed patients with LPRD and GERD. High-resolution esophageal manometry was used to gather data pertaining to the area pressure on the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), and the correlation between such pressure and symptom severity was determined. We compared the esophageal pressure of different UES and LES levels in the following categories: gender, age, BMI, and GERD severity. We analyzed correlations between esophageal pressure and clinical assessments among 90 patients with throat globus with laryngitis with LPRD. LPRD was measured using laryngoscopy, and GERD was measured using esophagoscopy and 24 h PH monitoring. There were no significant differences in the clinical assessments among the four grades of GERD. The LPRD patients with serious GERD had a lower UES and LES pressure. The lowest pressure and longer duration of LES and UES were also observed among patients with LPRD of grade D GERD. No significant differences in UES and LES pressures among ages, genders, or BMIs were noted.
