Objective: To investigate the functional outcomes and postoperative complications of Cheng's GIRAFFE reconstruction after proximal gastrectomy. Methods: A descriptive case series study was conducted. Clinical data of 100 patients with adenocarcinoma of the esophagogastric junction who underwent Cheng's GIRAFFE reconstruction after proximal gastrectomy in Cancer Hospital of University of Chinese Academy of Sciences (64 cases), Zhejiang Provincial Hospital of Chinese Medicine (24 cases), Lishui Central Hospital (10 cases), Huzhou Central Hospital (1 case) and Ningbo Lihuili Hospital (1 case) from September 2017 to June 2021 were retrospectively analyzed. Of 100 patients, 64 were males and 36 were females; the mean age was (61.3 ± 11.1) years and the BMI was (22.7±11.1) kg/m(2). For TNM stage, 68 patients were stage IA, 24 were stage IIA and 8 were stage IIB. Postoperative functional results and postoperative complications of radical gastrectomy with Giraffe reconstruction were analyzed and summarized. Gastroesophageal reflux disease questionnaire (RDQ) score and postoperative endoscopy were used to evaluate the occurrence of reflux esophagitis and its grade (grade N, grade A, grade B, grade C, and grade D from mild to severe reflux). The continuous data conforming to normal distribution were expressed as (mean ± standard deviation), and those with skewed distribution were presented as median (Q1, Q3). Results: All the 100 patients successfully completed R0 resection, including 77 patients undergoing laparoscopic surgery and 23 patients undergoing laparotomy. The Giraffe anastomosis time was (38.6±14.0) min; the blood loss was (73.0±18.4) ml; the postoperative hospital stay was 9.5 (8.2, 13.0) d; the hospitalization cost was (6.0±0.3) ten thousand yuan. Fourteen cases developed perioperative complications (14.0%), including 7 cases of pleural effusion or pneumonia, 3 cases of anastomotic leakage, 2 cases of gastric emptying disorder, 1 case of gastrointestinal hemorrhage and 1 case of anastomotic stenosis, who were all improved and discharged after symptomatic management. Patients were followed up for (33.3±1.6) months. Eight patients were found to have reflux symptoms by RDQ scale six months after surgery, and 11 patients (11/100,11.0%) were found to have reflux esophagitis by gastroscopy, including 6 in grade A, 3 in grade B, and 2 in grade C. All the patients could control their reflux symptoms with behavioral guidance or oral PPIs. Conclusion: Cheng's GIRAFFE reconstruction has good anti-reflux efficacy and gastric emptying function; it can be one of the choices of reconstruction methods after proximal gastrectomy.

OBJECTIVE: To analyze the differences in reflux patterns in 24-hour esophageal pH-impedance monitoring in patients with non-erosive reflux disease (NERD), reflux hypersensitivity (RH) and functional heartburn (FH) and explore the possible mechanism of symptoms in patients with heartburn and negative endoscopic findings. METHODS: Seventy-nine patients with heartburn as the main symptoms but negative endoscopic findings, including 35 with NERD, 16 with RH and 28 with FH, were enrolled in this study.All the patients underwent 24-h esophageal pH-impedance monitoring and esophagogastroscopy, and the results were compared among the 3 groups. RESULTS: Acid reflux episode was significantly increased and weakly alkaline reflux episode was significantly decreased in NERD group in comparison with RH group and FH group ( CONCLUSIONS Patients with NERD, RH and FH had different reflux patterns.Acid reflux is predominant in the NERD, while weakly alkaline reflux is significantly increased RH and FH.In patients with normal esophageal acid exposure but without symptoms or without recorded symptoms during esophageal pH-impedance monitoring, analysis of the total reflux episode, mixed reflux episode, proximal acid reflux episode and percentage can help in the differential diagnosis between RH and FH.

OBJECTIVETo investigate the feasibility of segmental pylorus-reservation gastrectomy in patients with early gastric cancer.

METHODA retrospective cohort study on clinical data of 6 patients strictly met the criteria of early gastric cancer locating in the middle of the stomach undergoing laparoscopic segmental gastrectomy from January 2014 to April 2016 at Department of General Surgery, Peking Union Medical College Hospital was carried out. Preoperative clinical staging revealed T1N0M0 for all the cases. One case received endoscopic mucosa resection(EMR) first, and postoperative pathology showed moderate differentiated adenocarcinoma invading substratum of mucosa, so a complementary laparoscopic segmental gastrectomy was performed. Surgical procedure was laparoscopic segmental gastrectomy with D1 or D2 lymph node dissection. Vagus nerve was not reserved during lymph node dissection in lesser curvature side. Number of resected lymph node, postoperative complication and long-term gastric function were observed.

RESULTOf 6 cases, 3 were male and 3 were female with age ranging from 55 to 59 years old. The distal resection margin was (4.6±0.5) cm away from pylorus. The average number of resected lymph node was 18.3±7.5 without metastasis. Follow-up time was 1 to 29 months for all the 6 cases and no relapse or metastasis was found during the follow-up. In 4 cases with follow-up beyond 1 year, 3 cases had slight distension in superior belly after meal and dyspepsia; another one case had vomiting nocturnal occasionally. Gastroscope examination one year after operation found food residue in all the cases. Images indicated the decrease of stomach size in all the cases. Two cases had esophagogastric reflux. All the patients had delayed gastric emptying symptoms after operations and were relieved within one year.

CONCLUSIONSIt is technically feasible to perform laparoscopic segmental gastrectomy in patients with early gastric cancer. Whether vagus nerve should be reserved requires further investigation.

BACKGROUND/AIMS: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease, with eosinophilic infiltration limited to the esophagus. A minority of EoE patients respond well to proton pump inhibitor (PPI) therapy alone, and that condition is labelled PPI-responsive esophageal eosinophilia (PPI-REE). The prevalence of PPI-REE among EoE cases is unknown. We aimed to identify clinical manifestations of PPI-REE, and the proportion of PPI-REE among all EoE cases. METHODS: We reviewed pathology of the 4,075 patients who underwent esophageal biopsy at an institution from March 2003 to July 2015. EoE was diagnosed based on esophageal symptoms and eosinophilic infiltration limited to the esophagus, with ≥15 eosinophils per high-power field. We collected endoscopic and pathologic findings, and clinical features for these patients. RESULTS: Thirteen (0.3%) patients were diagnosed with EoE. Clinical manifestations were dysphagia (30.8%), foreign body sensation (23.1%), regurgitation (23.1%), cough (15.4%), heartburn (15.4%), nausea (7.7%), dyspepsia (7.7%). The endoscopic findings noted were polypoid lesion (23.1%), whitish plaque or exudate (23.1%), linear furrow (7.7%), concentric ring (7.7%), nodularity (7.7%), erosion (7.7%), and normal (30.8%). Of these patients, five had a favorable course with PPI as monotherapy. CONCLUSIONS: The proportion of EoE among all patients undergoing endoscopic biopsy was 0.3%. Of those, PPI-REE comprised 38%. Most of the endoscopic findings were atypical or normal when compared to the typical findings in EoE. In conclusion, patients who present with symptoms related to esophageal dysfunction need esophageal biopsy, regardless of the endoscopic findings. Moreover, patients diagnosed with EoE need to be treated first with PPI alone.

Gastroesophageal reflux (GER) and cow's milk allergy (CMA) are common disorders in infants. In recent years, more and more research has investigated the relationship between these two diseases. Some studies reported that about half of the cases of GER in infants younger than 1 year may be an association with CMA. Therefore, overall understanding the role of CMA on the pathogenesis of GER has a great importance on improving clinical level of diagnosis and therapy. This review article tried to elaborate advances in research on the relationship between CMA and GER in infants, including epidemiology, pathogenesis, clinical manifestations, diagnosis and treatment.

BACKGROUND/AIMS: Proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE) is a newly recognized form of eosinophilic esophagitis (EoE) that responds to PPI therapy. It remains unclear whether PPI-REE represents a subphenotype of gastroesophageal reflux disease, a subphenotype of EoE, or its own distinct entity. The aim was to evaluate the clinicopathologic features of PPI-REE. METHODS: Six patients were diagnosed with PPI-REE based on symptoms, endoscopic abnormalities, esophageal eosinophilia with > or =15 eosinophils/high-power field, and a response to PPI treatment. Symptoms and endoscopic and pathological findings were evaluated. RESULTS: The median follow-up duration was 12 months. Presenting symptoms included dysphagia, heartburn, chest pain, foreign body sensation, acid reflux, and sore throat. All patients had typical endoscopic findings of EoE such as esophageal rings, linear furrows, nodularity, and whitish plaques. Three patients had a concomitant allergic disorder, and one had reflux esophagitis. Four patients exhibited elevated serum IgE, and five had positive skin prick tests. All patients experienced symptomatic resolution within 4 weeks and histologic resolution within 8 weeks after starting PPI therapy. There was no symptomatic recurrence. CONCLUSIONS: PPI therapy induced rapid resolution of symptoms and eosinophil counts in patients with PPI-REE. Large-scale studies with long-term follow-up are warranted.

About one-third of patients with suspected gastro-oesophageal reflux disease (GERD) do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to respond to PPIs include inadequate acid suppression, non-acid reflux, oesophageal hypersensitivity, oesophageal dysmotility and psychological comorbidities. Functional oesophageal tests can exclude cardiac and structural causes, as well as help to confi rm or exclude GERD. The use of PPIs should only be continued in the presence of acid reflux or oesophageal hypersensitivity for acid reflux-related events that is proven on functional oesophageal tests.

INTRODUCTIONThe presence of trigger factors may help to distinguish asthma from chronic obstructive pulmonary disease (COPD). Knowing and avoiding trigger factors for both asthma and COPD can facilitate the design of comprehensive management programmes that can aid disease control. This study aimed to describe the relative frequency and range of various trigger factors in asthma and COPD.

METHODSWe conducted a telephone-based survey involving asthma and COPD patients on follow-up at a university hospital in Singapore.

RESULTSA total of 779 asthma patients and 129 COPD patients participated in this study. Among these patients, 93.8% of those with asthma and 42.6% of those with COPD had trigger factors (p < 0.001). The median number of trigger factors was greater among asthma patients than among those with COPD (3 vs. 0, p < 0.001). Trigger factors found to be significantly more prevalent among asthma patients compared to those with COPD include tobacco smoke, alcohol, upper respiratory tract infections, incense smoke, perfume, laughter, a dusty environment, air-conditioning, heavy rain, heavy traffic fumes, citrus fruits, gastro-oesophageal reflux, household pets, flowers/pollen, medications and psychological triggers. Trigger factors that were not previously described, such as bathing, fatigue, insufficient sleep, crowded places and overeating, were also reported.

CONCLUSIONTrigger factors, although found in both groups of patients, were more common among asthma patients. Knowledge of these trigger factors may be useful in distinguishing between the two diseases and optimising disease management.

Chronic cough is one of the most common reasons for referral to a respiratory physician. Although fatal complications are rare, it may cause considerable distress in the patient's daily life. Western and local data shows that in patients with a normal chest radiograph, the most common causes are postnasal drip syndrome, postinfectious cough, gastro-oesophageal reflux disease and cough variant asthma. Less common causes are the use of angiotensin-converting enzyme inhibitors, smoker's cough and nonasthmatic eosinophilic bronchitis. A detailed history-taking and physical examination will provide a diagnosis in most patients, even at the primary care level. Some cases may need further investigations or specialist referral for diagnosis.

Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallow. These tests play a complimentary role in establishing the diagnosis of suspected achalasia. High-resolution manometry has now identified three subtypes of achalasia, with therapeutic implications. Pneumatic dilation and surgical myotomy are the only definitive treatment options for patients with achalasia who can undergo surgery. Botulinum toxin injection into the lower esophageal sphincter should be reserved for those who cannot undergo definitive therapy. Close follow-up is paramount because many patients will have a recurrence of symptoms and require repeat treatment.
