ABSTRACT
Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group. There were significant differences in the opera-tion time and postoperative pathological staging between the two groups ( t=2.62, χ2=5.93, P<0.05), and there was no significant difference in the reconstruction of digestive tract, duration of post-operative hospital stay, postoperative early complications between the two groups ( χ2=0.19, Z=0.40, χ2=2.50, P>0.05). (2) Follow-up. Of the 385 patients,202 cases were followed up during the post-operative 12 months, including 187 cases in the laparoscopic group and 15 cases in the open group. Cases with reflux esophagitis, cases with esophageal anastomotic stenosis were 48, 11 in patients of the laparoscopic group, versus 5, 2 in patients of the open group, showing no significant difference in the above indicators between the two groups ( P>0.05). The body mass index (BMI), hemoglobin (Hb), albumin (Alb) at postoperative 6 months and 12 months were (21±3)kg/m 2, (130±15)g/L, (40±4)g/L and (21±3)kg/m 2, (132±14)g/L, (41±4)g/L in patients of the laparoscopic group, versus (21±3)kg/m 2, (121±19)g/L, (37±5)g/L and (21±3)kg/m 2, (125±21)g/L, (43±6)g/L in patients of the open group. There were significant differences in postoperative Hb between the two groups ( Fgroup=5.88, Ftime=5.49, Finteraction=19.95, P<0.05) and there were significant differences in time effect of postopera-tive BMI and Alb between the two groups ( Ftime=9.53, 49.88, P<0.05). (3) Stratified analysis. ① Incidence of postoperative of reflux esophagitis and esophageal anastomotic stenosis in patients with different reconstruction of digestive tract. Of the 202 patients, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis were 168 and 34, respectively. The incidence rates of postoperative of reflux esophagitis were 26.79%(45/168)and 23.53%(8/34)in cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, showing no significant difference between them ( χ2=0.16, P>0.05). Cases undergoing esophageal anastomotic stenosis were 13 in patients with reconstruction of diges-tive tract as esophagogastric anastomosis. ② The BMI, Hb, Alb in patients with different reconstruc-tion of digestive tract. The BMI, Hb, Alb were (24±3)kg/m 2, (135±20)g/L, (41±5)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis before the operation, versus (23±3)kg/m 2, (130±19)g/L, (40±4)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis before the operation, showing no significant difference between them ( t=1.44, 1.77, 1.33, P>0.05). The BMI, Hb, Alb at postoperative 6 months and 12 months were (21±3)kg/m 2, (128±16)g/L, (39±4)g/L and (21±3)kg/m 2, (131±16)g/L, (41±4)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis, versus (20±4)kg/m 2, (133±13)g/L, (43±3)g/L and (21±3)kg/m 2, (135±12)g/L, (44±3)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis. There were significant differences in the group effect and time effect of postoperative Alb between patients with different reconstruction of diges-tive tract ( Fgroup=15.82, Ftime=5.43, P<0.05), and there was also a significant difference in the time effect of postoperative BMI between them ( Ftime=4.22 , P<0.05). Conclusion:LPG can be used to the treatment of proximal gastric cancer and adenocarcinoma of esophagogastric junction, with a good safety and short-term efficacy.
ABSTRACT
In recent years, the incidence of proximal gastric cancer and early gastric cancer as well as the proportion of proximal gastrectomy has been increased year by year. However, severe reflux esophagitis will occur after proximal gastrectomy, which will affect the quality of life of patients after operation. Therefore, the research on anti-reflux surgery has become a focus in the field across the world in recent years. Due to closing to the normal cardiac physiological structure, double muscle flap anastomosis has a good anti-reflux effect in proximal gastrectomy, which has been widely verified in clinical application. However, due to the disadvantages of traditional double muscle flap anastomosis, such as complex operation, long learning curve and high rate of anastomotic stenosis, researchers at home and abroad have continuously tried various modified muscle flap anastomosis. Among which, the modified double muscle flap anastomosis based on using the double barbed sutures has showed encouraging effects. At mean time, laparoscopic double muscle flap anastomosis through the left diaphragm muscle in the left thoracic cavity also further expands the application of double muscle flap anastomosis. The authors consult relevant research and focus on the discussion of current status and prospect of different modified muscle flap anastomosis in proximal gastrec-tomy, in order to promote the popularization and application of muscle flap anastomosis.
ABSTRACT
Laparoscopic techniques are more and more poplular in proximal gastrectomy. The traditional esophagogastric anastomosis may lead to severe reflux esophagitis after surgery, affecting patient's quality of life. In recent years, multiple methods of digestive tract reconstruction after laparoscopic proximal gastrectomy capable of resisting reflux have been applied to the clinic. Combining the results of the latest clinical studies and our clinical experience, we elaborate the views on digestive tract reconstruction after laparoscopic proximal gastrectomy. Esophagogastric anastomosis (posterior esophagogastric anastomosis, anterior esophagogastric anastomosis, gastric tube reconstruction, lateral esophagogastric anastomosis, Kamikawa anastomosis and modified Kamikawa anastomosis, etc.) and esophagojejunal anastomosis (interposition jejunum, interposition jejunum with pouch, and double-channel anastomosis, etc.) are mainly discussed. Of course, the anti-reflux mechanisms of different surgical procedures are not the same, the anti-reflux effects are variable, and the surgical difficulties under laparoscopy are also different. Therefore, how to choose a rational reconstruction method after proximal gastrectomy needs to be comprehensively considered based on patient's own situation and technical level of the surgeons.

Clinical data of 26 patients with proton pump inhibitor dependent gastroesophageal reflux disease (GERD) who underwent anti-reflux mucosectomy (ARMS) in Nanjing Drum Tower Hospital from July 2017 to December 2020 were reviewed, and the GERD questionnaire (GERD-Q) score, the short-form reflux-qual (RQS) score, esophageal motility and 24 h esophageal pH parameters before and after ARMS were compared. With a median follow-up period of 18.4 months (6-27 months), 23 (88.5%) patients reported symptomatic improvement and 15 (57.7%) patients discontinued the use of proton pump inhibitors. After ARMS, the mean scores of GERD-Q (6.23 VS 13.19, P=0.004) and RQS (26.67 VS 10.98, P<0.001) were significantly improved, the mean DeMeester score (10.69 VS 53.15, P<0.001), the mean acid exposure time percentage (3.56% VS 9.92%, P<0.001) and the mean number of acid reflux episodes (36.9 VS 139.9, P=0.001) were lower, and the mean rest pressure at lower esophageal sphincter (LES) (25.19 mmHg VS 13.63 mmHg, P<0.001) and the mean distal contractile integral (1 819.15 mmHg·s·cm VS 1 007.67 mmHg·s·cm, P<0.001) were significantly increased compared with those before surgery. ARMS has significant short-term efficacy in the treatment of proton pump inhibitor dependent GERD, which can effectively improve reflux symptoms and life quality of patients, and strengthen the rest pressure of LES and peristalsis of the esophageal body.
ABSTRACT
Biliary stent is an effective method for treating malignant biliary obstruction. However, duodenobiliary reflux is commonly found after conventional biliary stent, which causes complications such as biliary retrograde infection and stent blockage, and seriously reduces the quality of patients’ life. At present, anti-reflux biliary stent is considered as a promising palliative treatment method taking drainage and preventing duodenobiliary reflux into account. In this paper, research status of anti-reflux biliary stent was reviewed, and key problems such as design and evaluation of anti-reflux valve, valve and stent connection design, biomechanical analysis of anti-reflux biliary stent were mainly summarized. The current research progress and trend of anti-reflux biliary stent were summarized and analyzed.
ABSTRACT
Gastroesophageal reflux disease and its complications are harmful to human health. In recent years, due to the rising living standards and the changing diet structure of Chinese people, the incidence rate of gastroesophageal reflux disease in China is on the rise, and the awareness of clinicians on these diseases gradually increased. Laparoscopic anti-reflux surgery has become the main surgical method for the treatment of gastroesophageal reflux disease, and its curative effect has been widely recognized. At present, laparoscopic anti-reflux surgery for gastro-esophageal reflux disease has been carried out for more than 10 years in China, which has accumulated valuable experience and achieved rapid development, providing Chinese evidences for the academic community. Anti-reflux surgery for gastroesophageal reflux disease in China is also facing challenges and opportunities. How to promote anti-reflux surgery comprehensively, train professional clinicians, and improve the surgical efficacy is an important research topic of anti-reflux surgery in China. Based on the literatures at home and abroad and team experience, the authors reviewe the development of gastroesophageal reflux disease anti-reflux surgery in China, and look forward to the future development direction.
ABSTRACT
Objective: Traditional Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy can greatly decrease the anastomosis-related complications and reduce the incidence of reflux esophagitis, but its complexity limits the wide application. To decrease the complexity of Kamikawa anastomosis, the surgical team of Changzhi People's Hospital of Shanxi Changzhi Medical College improved this technique by using novel notion and reduced surgical procedures. This study aims to evaluate the efficacy and safety of modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy. Methods: A descriptive cohort study was carried out. Case enrollment criteria: (1) upper gastric carcinoma or esophagogastric junction carcinoma without distant metastasis was confirmed by preoperative gastroscopic biopsy and imaging examination; (2) tumor diameter was less than 4 cm; (3) preoperative clinical staging was cT1-3N1M0. Exclusion criteria: (1) patients received preoperative neoadjuvant chemotherapy; (2) patients had severe heart or lung disease, or poor nutritional status so that they could not tolerate surgery. Clinical data of 25 patients with upper gastric carcinoma or esophagogastric junction carcinoma who underwent modified Kamikawa anastomosis in digestive tract reconstruction in Heji Hospital (8 cases) and Changzhi People's Hospital (17 cases) from April 2019 to December 2020 were retrospectively collected. Of 25 patients, 21 were male and 4 were female, with mean age of 63.0 (49 to 78) years; 3 underwent open surgery and 22 underwent laparoscopic surgery. The modified Kamikawa anastomosis was as follows: (1) the novel notion of total mesangial resection of the esophagogastric junction was applied to facilitate the thorough removal of lymph nodes and facilitate hand-sewn anastomosis and embedding; (2) the diameter of the anastomotic stoma was selected according to the diameter of the esophageal stump, between 2.5 and 3.5 cm, to reduce the occurrence of anastomotic stenosis; (3) an ultrasonic scalpel was used to incise the esophageal stump, which could not only prevent bleeding of the esophageal stump, but also closely seal the esophageal mucosa, muscle layer and serosa to prevent esophageal mucosa retraction; (4) barbed suture was used to suture the remnant stomach fundus and esophagus to fix the stomach fundus in order to reduce the cumbersome and difficult intermittent sutures in a small space; (5) two barbed sutures were used to continuously suture the front and back walls of the anastomosis and complete the suture and fixation of the muscle flap. Relevant indicators of surgical safety, postoperative complications (using the Clavien-Dindo classification), esophageal reflux symptoms and the occurrence of esophagitis (using Los Angeles classification) were analyzed. The gastroesophageal reflux disease (GERD) score, gastroscopy, multi-position digestive tract radiography during postoperative follow-up were used to evaluate the residual gastric motility and anti-reflux efficacy. Results: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy was successfully performed in 25 patients. The surgical time was (5.8±1.8) hours, the intraoperative blood loss was (89.2±11.8) ml, and the average hospital stay was (13.8±2.9) days. Three cases (12.0%) developed postoperative anastomotic stenosis as Clavien-Dindo grade III and were healed after endoscopic dilation treatment. Postoperative upper gastrointestinal radiography showed 1 case (4.0%) with reflux symptoms as Clavien-Dindo grade I. Gastroscopy showed no signs of reflux esophagitis, and its Los Angeles classification was A grade. No anastomotic bleeding, local infection and death were found in all the patients. At postoperative 6-month of follow-up, GERD score showed no significant difference compared to pre-operation (2.7±0.6 vs. 2.4±1.0, t=-1.495, P=0.148). Conclusion: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy is safe and feasible with good anti-reflux efficacy.

ABSTRACT
Gastroesophageal reflux disease (GERD) is defined as refluxing of gastric contents to the esophagus, causing gastrointestinal tract symptoms and/or complications. Proton pump inhibitors are the first choice for the treatment of GERD, but have no such good effect as anti-reflux surgery on refractory GERD. Endoscopic anti-reflux procedures include transoral incisionless fundoplication (TIF), Stretta radiofrequency ablation, anti-reflux mucosectomy (ARMS), and endoscopic injection or implantation. Anti-reflux surgery involves laproscopic Nissen fundoplication (LNF), magnetic sphincter augmentation (MSA), electrical stimulation on the lower esophageal sphincter (LES), and bariatric surgery. This article introduces the progress in anti-reflux surgery for GERD.
ABSTRACT
Objective To observe the clinical characteristics of infants with pertussis syndrome and the influence of gastroesophageal reflux (GER) on pertussis syndrome in small infants, and provide experience for improving curative effect. Methods ① The clinical data of 807 infants with pertussis syndrome treated at Wuhan Children's Hospital from January 2015 to June 2017 were retrospectively analyzed, in which their clinical characteristics including symptoms, signs and related physical and chemical examinations were summarized. ② Prospective randomized controlled trials were performed at the Children's Hospital of Wuhan from June 2017 to June 2018, there were 120 infants with ages < 6 months diagnosed as pertussis syndrome and simultaneously accompanied by gastric volvulus (GV) and GER, and they were randomly divided into a study group and a control group according to the date sequence of definite diagnosis, 60 cases in each group. The control group was given conventional medical treatment, while in the study group, additionally the infants received massage to restore gastric proper position and anti-reflux therapy. The clinical efficacies of two groups were observed. Results ① Retrospective analysis showed that clinically, pertussis syndrome commonly occurred in infants of ages < 6 months, accounting for 88.30% (713 cases); all cases had spastic cough, and 60.00% (484 cases) infants' coughing was severer at night. In laboratory examinations, 83.27% (672 cases) of the infants had elevated platelets (PLT), 25.03% (202 cases) had abnormal myocardial zymograms, and 70.38% (568 cases) had elevated white blood cells (WBC). In the pathogen examination, only were pathogens found in 34.8% infants, mainly single pathogen infection, accounting for 86.12%. Chest radiographs suggested 71.50% of infants with pneumonia, and 73.00% of infants with GER, among which 77.92% of infants were accompanied by GV. ② The prospective study showed that in the treatment of infants with pertussis syndrome accompanied by GV and GER, manual massage should be used timely to correct GV and simultaneously anti-reflux therapy should be given, in the aspects of time required to improve cough symptoms (days: 5.36±1.40 vs. 6.59±1.56, P < 0.01) and shortening of the hospital stay (days: 6.50±1.41 vs. 8.09±1.63, P < 0.01) in the study group were superior to those in the control group; the case of respiratory failure in the study group was lower than that in the control group [2 cases vs. 8 cases, P < 0.05]. Conclusions In pertussis syndrome, lymphocytes occupy the main proportion of WBC elevation that is an important differential criterion between pertussis syndrome and infantile pneumonia with gastric volvulus and gastroesophageal reflux. PLT elevation in pertussis syndrome suggests that attention should be paid to the elevation as that might be related to the disease prognosis. It is necessary to further investigate whether the positive pathogen discovered in the course of pertussis syndrome is a pathogenic one, and attention should also be paid to the medical examination of GV and GER in the small infants with pertussis syndrome, since early proper intervention to correct GV and GER can significantly improve their clinical efficacies.
ABSTRACT
Objective To investigate the clinical efficacy of laparoscopic fundoplication for gastroesophageal reflux disease complicated with Barrett's esophagus.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 12 patients with gastroesophageal reflux disease complicated with Barrett's esophagus who were admitted to Beijing Chao-Yang Hospital of Capital Medical University between July 2012 to July 2016 were collected.Preoperative tests of patients included distal esophageal manometry and 24-hour pH monitoring,gastroscopy and upper gastroenterography.According to preoperative evaluation of patients,laparoscopic Nissen fundoplication was preferred,and laparoscopic Dor fundoplication was used for patients with discordant esophageal peristalsis function.Observation indicators:(1) surgical and postoperative recovery situations;(2) follow-up:① subjective changes of reflux symptoms;② distal esophageal manometry and 24-hour pH monitoring after operation;③ progression of esophageal mucosal lesions.Patients were followed up using outpatient examination and telephone interview with questionnaire at one month after operation and gastroscopy every 6 months up to June 2018.Measurement data with normal distribution were represented as (x)±s and measurement data with skewed distribution were described as M (range).Results (1) Surgical and postoperative recovery situations:of 12 patients,7 underwent laparoscopic Nissen fundoplication and 5 underwent laparoscopic Dor fundoplication.Seven patients complicated with esophageal hiatal hernia underwent laparoscopic repair of esophageal hiatal hernia,without conversion to open surgery.Operation time,volume of intraoperative blood loss and duration of hospital stay were (98±21) minutes,(27± 13) mL,(2.3± 1.2) days.There were no intraoperative and postoperative severe complications in the 12 patients.(2) Follow-up:12 patients were followed up for 20-42 months with a average time of 32 months.① Subjective changes of reflux symptoms:12 patients completed questionnaires at one month after operation.Scores of heartburn in the 12 patients were 0.Acid regurgitation in the 12 patients was relieved,requiring no acid-inhibitory drugs.Upper abdominal dull pain in 3/4 of the patients and retrosternal pain in 2 patients were relieved.Patients had mild dysphagia or abdominal distention at 2 weeks after operation and recovered to normal diet by dietary instruction within 4 weeks.Score of dysphagia was 2 (range,0-4) and no patient need hospitalization or surgical treatment.Score of surgery satisfaction was 9 (range,7-10) in the patients.② Distal esophageal manometry and 24-hour pH monitoring after operation:lower esophageal sphincter pressure and DeMeester score were (12.8 ± 2.8) mmHg (1 mmHg =0.133 kPa) and 11±3 respectively.③ Progression of esophageal mucosal lesions:2 of 9 patients with short Barrett's esophagus were detected complete regression of esophageal mucosal lesions at postoperative one year,1 was detected partial regression of esophageal mucosal lesions at postoperative one year and 6 were detected no change at postoperative 2 years.One of 3 patients with long Barrett's esophagus was detected partial regression of esophageal mucosal lesions at postoperative one year and 2 complicated with mild poor differentiation were detected no change at postoperative 2 years.Conclusion Laparoscopic fundoplication for gastroesophageal reflux disease complicated with Barrett's esophagus can improve subjective symptom and objective markers of patients and provide satisfactory efficacy.
ABSTRACT
Objective To explore the retrograde contamination of drainage bag outlets,and provide basis for the formulation of related guideline for healthcare-associated infection(HAI)management. Methods On October 14,2016,with sterile manipulation,urine,5% glucose solution,glucose normal saline,sterile water,and 0.9% nor-mal saline were injected into anti-reflux drainage bags(anti-reflux group)and common drainage bags(common group)respectively,entrances of bags were sealed and bags were hung in two ways:outlets were 10 cm away from the ground(suspended group)and touched the ground(ground-touching group)respectively,specimens were col-lected from bag outlets to perform bacterial culture every 3 days,a total of 10 times of cultures were performed,re-trograde contamination of drainage bag outlets was observed dynamically.Results Retrograde contamination rate of drainage bag outlets of anti-reflux group was significantly lower than common group(7.7% vs 46.0%,P=0.000);suspended group was significantly lower than ground-touching group(17.9% vs 35.8%,P=0.000). Retrograde contamination rates of outlets of drainage bags filled with different properties of liquid were as follows:urine (54.3%)>5% glucose solution(34.5%)>glucose normal saline(24.3%)>0.9% normal saline(10.8%)>ste-rile water(10.5%),pairwise comparison showed a significant difference(P=0.000).The initial occurrence time of contamination in anti-reflux group and common group was on the 13thday and 7thday respectively,two group was significantly different on the 7thday(P=0.041). There was a medium intensity correlation between the types of drainage bags and liquid properties(PearsonC=0.5).Conclusion Different types of drainage bags,retention time,and liquid property can impact retrograde contamination of drainage bag outlets,regular urine culture during the use of drainage bags should be paid attention in clinical practice,so as to use antimicrobial agents rationally and guide replacement time of drainage bags.
ABSTRACT
Because most surgeons perform an esophagectomy and colonic transposition as the main reconstruction method for patients with esophageal stenosis caused by swallowing corrosive materials, we report 2 cases in which ileocolonic transposition was used to treat such patients. Both patients displayed stenosis in the middle third of the esophagus. Their chief complaint was dysphagia. Ileocolonic transposition using vascularization of the Drummond and ileal arteries was followed by a prepared ileocolic graft by ligating ileocolic vessels. We performed an ileocolonic transposition esophagogastric bypass without an esophagectomy. All surgeries resulted in minimal intraoperative bleeding. Patients experienced no leakage, postoperative fistulas, dysphagia, or postoperative reflux. Three weeks after surgery, 1 patient experienced reversible hoarseness caused by extensive laryngeal-nerve manipulation. Cumulatively, ileocolonic transposition with cervical anastomosis for the treatment of patients with esophageal stenosis caused by corrosive esophageal injury can be considered to be an antireflux treatment because the ileocaecal sphincter is maintained.

ABSTRACT
Introducción: La alteración de la distensibilidad de la unión gastro esofágica (UGE) es un factor etiológico para la enfermedad de reflujo gastroesofágico. El incremento de la distensibilidad permite el reflujo de contenido gástrico incrementa las relajaciones transitorias del esfínter, el número de reflujos y la exposición al ácido. Ha sido descrito que la UGE puede ser calibrada en el acto operatorio utilizando sonda balón, que permite una medida en tiempo real de la capacidad, diámetro y presión de la UGE. Objetivos: evaluar la utilidad de la medida de la distensibilidad de la UGE como predictor de éxito en fundoplicatura laparoscópica (FPL) mediante el uso de la sonda Endoflip ® (Crospon) utilizada intra operatoriamente en pacientes sometidos a FPL como tratamiento anti reflujo practicando mediciones antes y después de la plicatura. Materiales y métodos: La FP se realizó según técnica de Toupet. Se tomaron medidas de distensión del balón con llenado de 40 ml de solución salina 0,2% a) después de la inducción de la anestesia b) después de la reparación de la crura y c) al finalizar el arropado. Los datos fueron analizados por t students. P<0,05 fue considerado significativo. Resultados: Fueron evaluados 9 pacientes, el promedio de edad fue de 45,2; en todos los pacientes existía indicación de cirugía, todos presentaban hernia hiatal. La FPL redujo el promedio de distensibilidad de la UGE de 52,8 mm2/mmHg a 29,8 mm2/mmHg (p=0,0021, (43,5%). Conclusión: Este método permite tomar decisiones en cirugía de la UGE donde el valor objetivo de la distensibilidad puede definir el éxito de la cirugía y evitar eventos adversos post operatorios.
Introduction: The altered distensibility of the gastro esophageal junction (GEJ) is recognized as a primary pathophysiologic factor in the development of gastro esophageal reflux disease (GERD). The increase in GEJ distensibility allows reflux of large volumes of gastric contents into the esophagus, increases transient relaxations of the lower esophageal sphincter and increases the number of reflux and esophageal exposure to acid. Moreover, other pathologies with functional obstruction of the GEJ as achalasia have very little distensibility. Recently was reported that GEJ can be calibrated during surgery using balloon catheter, allowing real-time measurement of capacity, diameter and GEJ pressure during surgery. Objectives: To review the usefulness of the measurement of the distensibility of the GEJ as a predictor of success in laparoscopic fundoplication (LP) using Endoflip® commercial catheter, used intra-operatively in patients undergoing LP anti reflux surgery practicing measurements before and after plication. Material and Methods: The Toupet Fundoplication (TFP) was performed under standard technique, balloon distension measurements were taken, filling with 40 ml of 0.2% saline solution as specified by the manufacturer: a) after induction of anesthesia and once the pneumo peritoneum was stabilized b) After repairing the crura of the diaphragm and c) after the wrapping. Data was analyzed by students t P <0.05 and was considered significant. Results: A total of 9 patients (6 men), age average was 45.2 (32-72), all patients had previous functional and endoscopic studies and surgical indication existed, they all had a diagnosis of hiatal hernia, they all signed informed consent. No patient had postoperative complications. The Toupet Fundoplication (TFP) significantly reduced average GEJ distensibility to 40 ml of 52.8 to 29.8 mm2/mmHg mm2/mmHg (p = 0.0021, which represents a reduction of 43.5%). Conclusion: This method allows the gastro surgical team to make decisions on GEJ surgery in which the target value of distensibility can define the success of the surgery and avoid postoperative adverse events.
ABSTRACT
Objective To discuss the effect of the application of anti-reflux venous indwelling needle after gastrointestinal polyps endoscopic resection.Methods 400 cases of patients after gastrointestinal polyps endoscopic resection were selected in our department.200 cases of patients using ordinary venous indwelling needle were set as the control group.In addition,200 cases of patients chose anti-reflux indwelling needles which were produced by a certain medical instrument Co.,Ltd were set as the experimental group.The incidence rate of phlebitis,tube blocking,blood return and indwelling time in the process of using anti-reflux indwelling needle were observed in two groups.Results During the indwelling time of two kinds of indwelling needles,the incidence rates of phlebitis,tube blocking and blood return of anti-reflux indwelling needle in the experimental group were significantly lower than those of the control group.The average indwelling time of the experimental group was 1.2 days,longer than that of the control group.Conclusions Anti-reflux indwelling needle can effectively protect the blood vessels,ensure the patients to use drugs in time,improve the work efficiency of nurses,reduce the damage to patients and effectively reduce the burden of patients.
