Abstract: Objective To evaluate the effect on gastroesophageal reflux and gastric emptying in the different route of gastroesophageal anastomosis objectively after esophagectomy for patients with midesophageal carcinoma. Methods Forty patients with midesophageal carcinoma were randomly divided into two groups. Esophageal bed group (n=20): the gastroesophageal anastomosis were performed while the stomach were pulled on through the esophageal bed after esophagectomy; endothoracic group (n=20): gastroesophageal anastomosis were performed while the stomach were pulled on in the thoracic cavity. Ten persons had no disease of digestive system and healthy volunteers were recruited as normal control group. 24-hour esophageal pH monitoring and radioisotope gastric emptying checkup were carried out in all experimental subjects 3 months after operation, so as to observe the changes of gastroesophageal reflux and gastric emptying. Results All of the patients’s operation were success. And no anastomotic leakage and no anastomotic stenosis. Three months after operation, the patients in both operation groups were with different level of reflux. DeMeester total appraise score, the times of regurgitation of gastric juice in 24h, gt;5 min reflux frequency, the longest time of keep reflux, pHlt;4.00 total time and pHlt;4.00 of total time percent, these targets in both operation groups were higher than those in control group (Plt;0.01) DeMeester total appraise score, the times of regurgitation of gastric juice in 24 hours, the longest time of keeping reflux, pHlt;4.00 of total time and pHlt;4.00 of total time percent in esophageal bed group were lower than those in endothoracic group(Plt;0.01). The recent period of gastric emptying percentage (GE) in both operative groups were lower than that in normal control group. GE in esophageal bed group experimental meal in the stomach after entering the 30,60,90,120,180 and 240 min were higher than those in endothoracic group. Conclusion After the operation of esophagogastric anastomosis through esophageal bed in upper aortic site,gastroesophageal reflux and delayed gastric emptying exist objectively, However, the technique is superior to the traditional technique to reduce the extent of gastroesophageal reflux and delayed gastric emptying, its mechanism might be the result of mechanical factors.
Objective To compare the short-term curative results between Nissen, Thal and Toupet fundoplications in treatment of gastroesophageal reflux(GER) and to provide the basis for operative procedure. Methods Thirty-three male Japan rabbits were randomly divided into six groups: group reflux(n=7), transabdominal Heller’s esophagomyotomy (TAHE)；group Nissen(n=7)，TAHE and Nissen fundoplication；group Thal(n=7)，TAHE and Thal fundoplication；group Toupet(n=7)，TAHE and Toupet fundoplication； control group (n=5)，ventrotomy. The anti-reflux efficacy of fundoplication was evaluated by intraesophageal pH monitoring and MGV（maximal gastric volume sustained by lower esophageal sphincter）4 weeks postoperatively. Results ① The total number of reflux episodes and the reflux ratio（0.83±0.41,2.20%±1.12%） of group Nissen were significantly lower than those of group Thal (2.20±0.45, 4.32%±0.82%) and group Toupet (1.80±0.45, 4.20%±0.57%), respectively (Plt;0.05). ② MGV of group Nissen (233.00±9.44)ml was significantly larger than those of group Thal （203.40±11.13）ml and group Toupet（197.60±10.99）ml, respectively (Plt;0.05). ③There were no significant difference in total number of reflux episodes, reflux ratio and MGV between group Thal and group Toupet (Pgt;0.05).Conclusion Nissen fundoplication was better than Thal and Toupet fundoplications,Thal and Toupet fundoplications are similar in short-term curative result.
Objective We aimed to evaluate the prevalence of H.pylori infection and the prevalence of cagA+ strains in patients with and without Barrett’s esophagus. Methods A full literature search to February 2008 was conducted in PubMed, MEDLINE and EMbase databases to identify case-control studies or cohort studies evaluating the prevalence of H.pylori in patients with or without Barrett’s esophagus. Summary odds ratios (OR) and 95% confidence interval (CI) were calculated by RevMan 4.2.8. Results Nineteen studies were identified (16 case-controlled studies and 3 cohort studies). In case controlled studies, the prevalence of H.pylori infection significantly decreased in patients with Barrett’s esophagus as compared subjects with normal endoscopic appearance, with a overall OR of 0.56 (95%CI 0.40 to 0.79). The prevalence of H.pylori infection was no statistically significant difference in patients with Barrett’s esophagus as compared to those with gastroesophageal reflux disease, with a overall OR of 0.86 (95% CI 0.74 to 1.00). In cohort studies, the prevalence of H. pylori was no statistically significant difference in patients with Barrett’s esophagus as compared to patients with normal endoscopic appearance or patients with gastroesophageal reflux disease, with a overall OR of 1.12 (95%CI 0.77 to 1.61) and 1.10 (95%CI 0.32 to 3.83). When the analysis was stratified by the status of cagA, the prevalence of cagA positive strains significantly decreased in patients with Barrett’s esophagus as compared both to subjects with normal endoscopic appearance with OR 0.30 and 95% CI 0.12 to 0.74, and to those with gastroesophageal reflux disease (OR 0.55; 95%CI 0.33 to 0.94). Irrespective of the presence of intestinal metaplasia, similar magnitude for the reduction of H.pylori infection was observed for patients with Barrett’s esophagus and those with normal endoscopic appearance. While accompared with the presence of intestinal metaplasia, Barrett’s esophagus was associated with a significantly reduction as compared to the patients with gastroesophageal reflux disease (OR 0.81, 95%CI 0.68 to 0.98). When stratified analyses were performed, a significant reduction of H.pylori infection was observed only in patients with long-segment Barrett’s esophagus (OR 0.54; 95%CI 0.35 to 0.82), but not in those with short-segment Barrett’s esophagus (OR 0.72; 95%CI 0.43 to 1.20). Conclusion This meta-analysis indicated that the prevalence of H.pylori infection, especially the prevalence of cagA positive strains was significantly lower in patients with Barrett’s esophagus than in subjects with normal endoscopic appearance. However, the prevalence of H. pylori infection was no statistical difference in patients with Barrett’s esophagus as compared to those with gastroesophageal reflux disease. Colonization with cagA positive strains may be protective against the formation of Barrett’s esophagus.
ObjectiveTo summarize basic research progress and current status of clinical diagnosis and therapy for gastroesophageal reflux disease. MethodRelated literatures were collected to review the pathogenesis, clinical manifestations, diagnosis and therapy of gastroesophageal reflux disease. ResultsGastroesophageal reflux disease was caused by many factors, such as hiatus hernia, hypotensive lower esophageal sphincter pressure, acid pocket, prolonged esophageal clearance, and delayed gastric emptying. Extra-esophageal symptoms was a common clinical presentation to gastroesophageal reflux disease. The diagnosis methods for gastroesophageal reflux disease included the symptom observation, gastroscopy examination, 24 h pH monitoring of esophageal, proton pump inhibitor test, questionnaire of gastroesophageal reflux disease and so on. The laparoscopic fundoplication could essentially treat the pathophysiologic abnormalities of gastroesophageal reflux disease, which had an obvious curative effect and wide application prospect. ConclusionPathogenesis, diagnosis, and therapy of gastroesophageal reflux disease are associated with multiple factors, which is still controversial and remains to be further studied.
ObjectiveTo compare the curative effect of biliopancreatic diversion with duodenal switch (BPD/DS) with different gastrointestinal anastomotic position in the rat with obese diabetes. MethodsThe obese diabetic rat models were induced by high-fat feeding for 1 month combined with intraperitoneal injection of low-dose streptozotocin (35 mg/kg), then which were divided into modified BPD/DS (M-BPD/DS), BPD/DS, sleeve gastrectomy (SG), and sham operation (SO) groups according to the operation performed. Eight rats in each group were randomly selected for following experimental observation. The situation of weight loss, glucose reduction, nutrition, and esophagitis were compared among 4 groups, especially between the M-BPD/DS and BPD/DS groups. Results① The body mass and food intake of rats in the M-BPD/DS and BPD/DS groups at 1–4 month(s) after operation (except food intake at the 4th month) were lower than those in the SO group (P<0.05), but it was found that the food intake of the M-BPD/DS group was higher than that of the BPD/DS group at the first month after operation (P<0.05). ② The fasting blood glucose levels of the M-BPD/DS and BPD/DS groups were lower than those of the SO group (P<0.05) and were lower than those before the operation (P<0.05), but which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). ③ The area under receiver operating characteristic curve (AUC) of blood glucose level by oral glucose tolerance test, insulin tolerancetest (ITT), and the homeostasis model assessment-insulin resistance index at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were lower of the SO group (P<0.05) and before operation (P<0.05), but which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). It was also found that the AUCs of ITT values at the 4th month after operation of the M-BPD/DS and BPD/DS groups were higher than those of the 1st month after operation (P<0.05). ④ The AUCs of the glucagon like peptide-1 (GLP-1) levels at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were higher than those of the SO group (P<0.05), while the AUCs of the insulin index were lower than those of the SO group (P<0.05) at 1 and 4 months after operation. At the 1st and 4th month after operation, the AUCs of the GLP-1 were higher and the insulin were lower than those before operation (P<0.05) in the M-BPD/DS and BPD/DS groups, which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). ⑤ The albumin, calcium, and ferrum at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were statistically lower than those of the SO group (P<0.05) and lower than those before operation (P<0.05). ⑥ The thickness of esophageal squamous epithelium and rate of nipple elongation of the M-BPD/DS group were lower than those of the BPD/DS group (P<0.05). ConclusionThe results of this experiment suggest that moving the gastrointestinal anastomosis above the pylorus simplifies the operationof BPD/DS without affecting its weight loss and glucose lowering effect , and may have a protective effect on the esophagus.
Objective To analyze the relationship between neuroticism and gastroesophageal reflux disease (GERD) using the Mendelian randomization (MR) method. Methods Exposure and outcome data were downloaded from the Integrative Epidemiology Unit (IEU) database in August 2023, including summary statistics from genome-wide association studies (GWAS) for neuroticism (n=374 323) and GERD (n=602 604). MR was conducted using the weighted median method, MR-Egger method, inverse variance weighted method, weighted mode method, and simple mode method. The causal relationship between the two was assessed using odds ratio (OR), and sensitivity analyses were performed to ensure the accuracy of the results. ResultsNeuroticism was associated with an increased risk of GERD [OR=1.229, 95%CI (1.186, 1.274), P<0.001]. Similarly, GERD was associated with an increased risk of neuroticism [OR=1.786, 95%CI (1.623, 1.965), P<0.001]. Conclusion There is a bidirectional causal relationship between neuroticism and gastroesophageal reflux disease.
ObjectiveTo investigate the clinical effects of laparoscopic hiatus reconstruction with Bard Crurosoft patch associated with Nissen fundoplication in elderly patients with gastroesophageal reflux disease (GERD). MethodsFrom July 2006 to July 2009, 22 consecutive elderly patients （≥65 years） with GERD underwent laparoscopic hiatus reconstruction associated with Nissen fundoplication， 10 of them underwent laparoscopic Crurosoft patch hiatus reconstruction (hiatus diameter≥5 cm in 2 patients， lt;5 cm in 8 patients) and 12 underwent laparoscopic simple sutured hiatus reconstruction (hiatus diameter≥5 cm in 2 patients， lt;5 cm in 10 patients). Intra and perioperative data including symptoms (heartburn, regurgitation, dysphagia, and respiratory complications), functional evaluations (esophagogastroscopy, manometric evaluations in lower esophageal segment, and 24 h pH-monitoring values) were compared and analyzed. ResultsPatients in 2 groups had similar preoperative values in demographics, symptom scores, functional evaluations, as well as operative data except for mean operative time. Three-month and 1-year follow-up after operation, the results of symptoms scores and functional evaluations of patients in 2 groups compared with preoperative values wear improved （Plt;0.05）, but symptoms scores and functional evaluations of patients in patch group were evaluated to demonstrate more significant improvement than suture group （Plt;0.05）. In suture group, the results of 3 months after operation were better than 1 year after operation, with statistically significant difference （Plt;0.05）. Two patients underwent postoperative intrathoracic immigration of wrap in suture group, but this complication did not happen in patch group （Plt;0.05）. ConclusionsLaparoscopic hiatus reconstruction with Bard Crurosoft patch associated with Nissen fundoplication is a safe and effective treatment for elderly patients(≥65 years) with GERD.
Objective To investigate the gastrin level in patients with type 2 diabetes mellitus (T2DM) with gastroesophageal reflux disease (GERD), and analyze the possible mechanism of gastrin in the pathogenesis of T2DM combined with GERD. Methods Thirty-eight patients with T2DM combined with GERD treated between January 2013 and January 2015 were designated as group A; 40 patients with T2DM only were regarded as group B; 36 patients with GERD only were regarded as group C; and another 40 healthy volunteers who underwent physical examination at the same period were regarded as group D. The fasting serum levels of gastrin were measured and compared among the above four groups. Results The fasting serum level of gastrin was significantly higher in group A [(116.53±22.02) pg/mL] than group B [(101.89±20.76) pg/mL], group C [(90.04±21.16) pg/mL], and group D [(92.48±19.69) pg/mL] (P<0.01). The fasting serum level of gastrin in group B was significantly higher than group C and D (P<0.05). There was no significant difference between group C and D in terms of fasting serum level of gastrin (P>0.05). Conclusions There is a high level of gastrin in patients with GERD combined with T2DM. Abnormal secretion of gastrin may be closely related with the occurrence and development of T2DM and GERD.
ObjectiveTo present the safety and efficiency of laparoscopic Nissen fundoplication for hiatal hernia in elderly patients. MethodsClinical data of 35 elderly patients with hiatal hernia who underwent laparoscopic Nissen fundoplication in The Affiliated Hospital of Xuzhou Medical College between August 2013 and March 2014 was retrospectively analyzed. ResultsAll patients underwent laparoscopic Nissen fundoplication. The operation time was 72-minute in average (65-105 minutes) and intraoperative blood loss was 30 mL in average (10-120 mL). The mean value of postoperative hospital stay was 5-day (3-23 days). Patients' stomachs and esophagus were restored to normal position after surgery. No complication was noted except 2 patients had mild gastroesophageal reflux after operation, and 1 patient suffered from transient dysphagia after operation, all the symptoms subsided after conservative treatment. Afterwards, 33 of them achieved follow-up for 6 to 12 months (mean of 8.5 months), the other 2 patients were lost to follow-up. During the follow-up period, a questionnaire regarding to the criteria for Reflux Diagnostic Questionnaire (RDQ) score were conducted in the 33 patients, and the results showed that the symptoms including acid reflux, heartburn, chest pain, cough, dyspnea, lump sensation in the pharynx, and hoarseness were improved significantly in 6 months after operation (P<0.05), and no recurrence was found during the follow-up period. ConclusionLaparoscopic Nissen fundoplication is a safe operation for elderly patients with hiatal hernia, and it can achieve good clinical result.
ObjectiveTo evaluate laparoscopic anti-reflux surgery for treatment of chronic obstructive pulmonary disease (COPD) associated with gastroesophageal reflux disease (GERD).MethodsA total of 20 patients with GERD and COPD underwent laparoscopic anti-reflux procedure in the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2017. The reflux diagnostic questionnaire, pulmonary function, COPD assessment test scale, 24-hour esophageal pH-impedance monitoring and esophageal pressure measurement were performed in all patients. All drug-refractory patients underwent the laparoscopic anti-reflux surgery. After 12 months follow-up, the parameters of COPD and GERD were evaluated again.ResultsTwenty patients with COPD and GERD were successfully performed laparoscopic anti-reflux surgery, no hernia patch repair patient and death patient occurred. There was no esophageal rupture, bleeding, infection, and other serious postoperative complications. Although 8 patients had the different degree dysphagia and 10 patients had the different degree abdominal distention, they all relieved themselves. Twenty patients with GERD and COPD were followed up for 1 year. Compared with the values before treatment, the GERD symptom score, reflux times, DeMeester score, and COPD assessment test score of the patients were significantly reduced (P<0.05), the lower esophageal sphincter pressure, percentage of forced expiratory volume in one second (FEV1) in the predicted value and FEV1/forced vital capacity (FVC) were significantly increased (P<0.05) after the treatment. According to the grading standard of The Global Initiative for Chronic Obstructive Lung Disease (GOLD), 5 cases of grade Ⅰ, 2 cases of grade Ⅱ and 1 case of grade Ⅲ were cured; 1 case of grade Ⅰ, 4 cases of grade Ⅱ and 4 cases of grade Ⅲ were improved; 1 case of grade Ⅰ, 1 case of grade Ⅱ and 1 case of grade Ⅳ were ineffective. The total effective rate was 85% (17/20).ConclusionsCOPD is closely related to GERD. Laparoscopic anti-reflux surgery can not only effectively treat GERD, but also markedly improve COPD.
