ABSTRACT
Objective:To analyze the difference and clinical significance of reflux related parameters between patients with reflux asthma (RA) and typical gastroesophageal reflux disease (TGERD).Methods:From June 2017 to June 2020, at PLA Rocket Force Characteristic Medical Center, the clinical data of 120 patients with gastroesophageal reflux disease (GERD) who underwent gastroscopy, high-resolution esophageal manometry (HREM) and 24 h pH-impedance monitoring contemporaneously were retrospectively analyzed. The GERD patients were divided into RA group and TGERD group according to the symptom correlated indexes, 60 cases in each group. The reflux related indexes of two groups were compared, which included reflux esophagitis (RE) score, esophageal hiatal hernia, Hill grade score of gastroesophageal flap valve, upper esophageal sphincter (UES) pressure, DeMeester score, and reflux episodes. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:There were no significant differences in RE score and Hill grade score between TGERD group and RA group (0.0, 0.0 to 1.0 vs. 0.0, 0.0 to 1.8; 3.0, 2.0 to 3.0 vs. 3.0, 2.0 to 3.0) (both P>0.05). The detection rate of UES pressure less than 34 mmHg (1 mmHg=0.133 kPa) of RA group was higher than that of TGERD group (41.7%, 25/60 vs. 23.3%, 14/60), and the difference was statistically significant ( χ2=4.596, P=0.032). The UES pressure of RA group was lower than that of TGERD group (51.7 mmHg, 23.6 mmHg to 70.1 mmHg vs. 62.0 mmHg, 37.4 mmHg to 77.4 mmHg), and the difference was statistically significant ( Z=-2.105, P=0.035). There were no significant differences in other parameters of HREM between TGERD group and RA group (all P>0.05). The detection rates of DeMeester score more than 14.7, acid exposure time more than 4.5% and total reflux episodes more than 73 episodes of RA group were all higher than those of TGERD group (41.7%, 25/60 vs. 23.3%, 14/60; 40.0%, 24/60 vs. 21.7%, 13/60; 38.3%, 23/60 vs. 20.0%, 12/60, respectively), and the differences were all statistically significant ( χ2=5.546, 4.728 and 4.881, all P<0.05). The total reflux episodes and weak acid gas reflux episodes of RA group were both higher than those of TGERD group (60 episodes, 43 episodes to 98 episodes vs. 52 episodes, 34 episodes to 69 episodes; 12 episodes, 6 episodes to 21 episodes vs. 9 episodes, 3 episodes to 14 episodes), and the differences were statistically significant ( Z=-2.323 and -2.053, both P<0.05). There were no significant differences in other parameters of 24 h pH-impedance monitoring between TGERD group and RA group (all P>0.05). Conclusion:Low UES pressure, abnormal esophageal acid exposure and increased reflux episodes, especially weak acid gas reflux episodes, may be more likely to induce RA.
ABSTRACT
Objective To evaluate the effectiveness and complications of laparoscopic repair for hiatal hernia.Methods The clinical data of 992 patients with hiatal hernia undergoing laparoscopic repair from Jan 2008 to June 2014 were collected and analyzed.Postoperative symptom scores,postoperative complications,recurrence rate and satisfaction were evaluated.Results 858 cases were followed up,including type Ⅰ HH accounting for 79.8％,type Ⅱ for 1.3％,type Ⅲ for 17.1％,type Ⅳ for 1.8％ respectively.HH repaired with mesh in 520 cases.The overall improvement rate was 96.2％.Postoperative symptom scores significantly decreased.Recurrence of anatomy and symptoms were 31 and 15 cases respectively.Short-term and long-term of postoperative complications were 35.8％ and 5.6％ respectively.Excellent,fair and poor result were achieved in 91.8％,4.3％,3.9％ of postoperatively follow-up cases,respectively.Conclusion The laparoscopic approach for repair of hiatal hernias is of minimally invasive,lower recurrence rate,less complications and high satisfaction.
ABSTRACT
Objective To investigate the relationship between obesity and esophageal high resolutionmanometry ,24‐hour pH monitoring and gastroscopic results of patients with gastroesophageal reflux disease (GERD) .Methods A total of 196 patients with GERD(DeMeester score>14 .72) were selected and divided into normal weight group (18 .5 kg/m2 0 .05) .The percent total time pH≤4 of obesity group was 15 .42% (10 .31% to 21 .49% ) ,percent supine time pH≤4 was 14 .21% (5 .75% to 34 .98% ) and percent upright time pH≤4 was 14 .25% (8 .19% to 18 .13% ) .The reflux episodes (106 .50 ,67 .00 to 145 .75) and the longest duration of reflux episodes (28 .10 min ,10 .90 min to 47 .93 min) were more than those of normal group (9 .74% ,5 .35% to 15 .96% ;7 .31% ,3 .25% to 11 .80% ;8 .45% ,5 .43% to 17 .48% ;72 .50 ,53 .00 to 100 .50;15 .80 min ,9 .90 min to 21 .28 min) and overweight group (11 .36% , 6 .74% to 15 .87% ;7 .74% ,2 .36% to 15 .05% ;11 .27% ,3 .37% to 14 .73% ;85 .50 ,58 .75 to 117 .75;21 .40 min ,11 .50 min to 39 .90 min) ,and the differences were statistically significant (Z=7 .054 ,11 .181 , 6 .429 ,6 .452 ,8 .246 ,all P0 .05) .There was no statistically significant difference in the incidence of Barrett′s esophagus among three groups (all P>0 .05) .Conclusions Compared with that of normal weight group and overweight group of patiento with GERD ,abdominal length of LES of obesity group was shorter .With an increase in BMI , acid exposure and the incidences of reflux esophagitis and hiatal hernia also increased .
