Clinical effects of robot-assisted esophageal hiatal hernia repair and laparoscopic esophageal hiatal hernia repair: a retrospective comparative study / 中华外科杂志

Objective: To analyze the short-term clinical effects of robot-assisted and laparoscopic repair of the hiatal hernia. Methods: The clinical data of 56 patients underwent minimally invasive hiatal hernia repair from January 2021 to January 2022 in the Department of Minimally Invasive Surgery, Hernias and Abdominal Wall Surgery, People's Hospital of Xinjiang Uygur Autonomous Region were retrospectively analyzed. There were 32 males and 24 females, aging (59.7±10.7) years (range: 28 to 75 years). All patients were divided into laparoscopy group (n=27) and robot group (n=29) according to surgical procedures. Perioperative conditions, hospital stay, and improvement in symptoms before and after surgery were compared between the two groups by the t test, Wilcoxon rank-sum test and χ2 test. Results: All surgical procedures were successfully completed, without conversion to laparotomy or change in operation mode. There were no serious complications related to the operation. The intraoperative blood loss of the robot group was less than that of the laparoscopic group (M (IQR)): (20 (110) ml vs. 40 (80) ml, Z=-4.098, P<0.01). The operation time ((111.7±33.6) minutes vs. (120.4±35.0) minutes, t=-0.943, P=0.350) and hospitalization time ((3.9±1.4) days vs. (4.7±1.9) days, t=-1.980, P=0.053) of the robot group and the laparoscopic group were similar. Follow-up for 12 months after the operation showed no postoperative complications and recurrence. The score of the health-related quality of life questionnaire for gastroesophageal reflux disease in the robot group decreased from 10.8±2.8 before the operation to 6.5±0.6 after the operation, and that in the laparoscopic group decreased from 10.6±2.1 before the operation to 6.3±0.6 after the operation. There was no difference in the influence of different surgical methods on the change in score (t=0.030,P=0.976). Conclusion: Compared with laparoscopic repair of the hiatal hernia, robot-assisted hiatal hernia repair has the advantages of less bleeding, rapid postoperative recovery and good short-term effect.

Abuse of diphenoxylate and related factors of forced drug abstainer in Gansu province / 中华流行病学杂志

Objective: To investigate the prevalence of diphenoxylate abuse and related factors of forced drug abstainer in Gansu province. Methods: By using a self-designed questionnaire, an epidemiologic investigation was carried out among 2 108 forced drug abstainer selected from the compulsory isolation detoxification center of Gansu province. A case-control study was conducted to analyze the factors related with diphenoxylate abuse. Results: The diphenoxylate abuse rate among forced drug abstainer in Gansu was 19.8% (406/2 046), ranking first in medical drug abuse. Multiple logistic regression analysis showed that factors as relieving withdrawal symptoms (OR=2.08, 95%CI: 1.01- 4.32), ways to obtain diphenoxylate (other ways: OR=1.00; regular clinic: OR=27.67, 95%CI: 2.64-289.82; friend: OR=0.01, 95%CI: 0.01-0.03), degree of euphoria (high: OR=1.00; medium: OR =3.36, 95%CI: 1.18-9.55; low: OR=26.16, 95%CI: 10.30-66.42), years of drug abuse (<5 years: OR=1.00; 10-15 years: OR=2.48, 95%CI: 1.02-6.04), abuse at home or in friend's house (OR=3.04, 95%CI: 1.08-8.68), abuse in car (OR=0.05, 95%CI: 0.00-0.68) and detoxification for the first time (OR=0.61, 95%CI: 0.43-0.86) were the possible influencing factors for diphenoxylate abuse. Conclusions: The prevalence of diphenoxylate abuse in forced drug abstainer in Gansu was relatively high. Reasons of abusing, the way to obtain diphenoxylate, whether using drug together with friends, degree of euphoria, years of abuse, abuse place and times for detoxification were related factors influencing the abuse of diphenoxylate.

Epidemiological characteristics and related risk factors on placental abruption in Hebei province / 中华流行病学杂志

Objective: The aim of this study was to assess the risk factors and epidemiological characteristics of placental abruption (PA) in Hebei province. Methods: A cross-sectional survey was conducted to collect data on 218 880 pregnant women who were hospitalized in 22 hospitals which were under a monitoring program, in Hebei province, from January 1, 2013 to December 31, 2016. Data regarding epidemiological characteristics as time distribution, population distribution and related risk factors of placental abruption were gathered and analyzed. Results: In this cohort study, 218 880 women were included, with 669 (0.31%) of the pregnant women having PA. The overall prevalence rates were higher in the South than in the north parts of the area and higher in more developed regional economic centers. The average age of women having the episode was (27.87±4.50) years and presented "J" distribution on the prevalence of maternal age. Results from the multivariate regression analysis showed that the following factors were independently at risk for placental abruption: pregnancy the including hypertension (OR=1.65, 95%CI: 1.09-2.50), mild preeclampsia (OR=3.65, 95%CI: 2.40-5.56), severe preeclampsia (OR=4.72, 95%CI: 3.86-5.76) and anemia (OR=2.41, 95%CI: 2.05-2.83) which were all increased in pregnant women with PA compared with the normal female population without placental abruption. Conclusions: Placental abruption seemed to be associated with a moderate increasing risk of age, and was seen higher in those population older than 35 or younger than 20 year-olds. It was suggested that appropriate inoculation programs should be taken in different regions, especially on high-risk groups. Health education on related disease was of great significance for improving the prenatal outcome.
