Laparoscopic total left-sided surgical approach versus traditional bilateral surgical approach for treating hiatal hernia: a study protocol for a randomized controlled trial

Application of Intravenous Anesthesia in Laparoscopic Hiatal Hernia Repair of Children

In order to solve the stress problem in laparoscopic hiatal hernia repair of children, improve surgical safety, and reduce surgical risk, this study compared the perioperative changes of epinephrine, norepinephrine, IL-6, IL-10, and hemodynamics in children undergoing laparoscopic surgery under intravenous general anesthesia and general anesthesia combined with an epidural block. In this study, 40 children aged 1-3 years who planned to undergo laparoscopic ortopexy and those who planned to undergo laparoscopic high ligation of hernia sac, aged 23.84 1.6 months and weighed 14.9 1.1 kg, were randomly divided into general anesthesia combined with the epidural block group (group A) and a total intravenous anesthesia group (group B), with 20 subjects in each group. The results are as follows: There were no differences in age, gender, body weight, anesthesia time, pneumoperitoneum duration, and functional time between the two groups. Cytokines: Compared with T0, the levels of IL-6 in T2, T3, T4, and T5 groups were significantly increased (P < 0.01). IL-10 levels: T2, T3, T4, and T5 groups were further increased, and the difference was statistically significant compared with T0 (P < 0.01). There was no difference between groups (P > 0.05). The recovery time in group B was shorter than that in group A (P < 0.01), and the total amount of propofol and fentanyl in group B was less than that in group A (P < 0.01). Through research on intravenous anesthesia treatment, it has been proved that total intravenous anesthesia can relieve perioperative pressure, reduce intravenous injection, and reduce the recovery time of children. However, its effect on cytokines is not obvious, so intravenous anesthesia is the most appropriate anesthesia mode in laparoscopic hiatal hernia repair surgery, which has practical significance.

A new technique for treating hiatal hernia with gastroesophageal reflux disease: the laparoscopic total left-side surgical approach

Introduction

Although the traditional bilateral surgical approach to treat hiatal hernia (HH) with gastroesophageal reflux disease (GERD) can provide local protection of the vagus nerve, the integrity of the entire vagus nerve cannot be evaluated. Therefore, we developed and described the total left-side surgical approach (TLSA), which theoretically reduces injury to the vagus nerve, and described the detailed surgical procedure.

Methods

Initially, we performed a cadaver study to explore the characteristics of the vagus nerve. Then, we prospectively evaluated the TLSA in 5 patients with HH and GERD between June 2020 and September 2020. Demographic characteristics, surgical parameters, perioperative outcomes, and follow-up findings were analyzed.

Results

The TLSA was successfully used in five patients (40–64 years old), and no major complications were noted. The median total operative time was 114 min, median blood loss was 50 mL, and median postoperative hospital stay was 3.8 days. Gastrointestinal function recovered within 4 days of surgery in all the patients. The 6-month follow-up gastroscopy examination showed well-established gastroesophageal flap valves. Compared with the baseline results, the 6-month follow-up results showed lower values for the total GerdQ score (12.4 vs. 6.2) and the total esophageal acid exposure time (3.48% vs. 0.38%). Based on the European Organization for Research and Treatment of Cancer quality of life questionnaire-stomach module 52 results, the incidence of dysphagia and flatulence decreased over time after the TLSA.

Conclusions

The TLSA provides a clear and broad surgical field, less trauma, and rapid recovery; moreover, it is technically simple. Although our results suggest that the TLSA provides safety and short-term efficacy and is feasible for patients with HH and GERD, long-term results from a larger clinical trial are needed to validate these findings.

Current Advancement on the Dynamic Mechanism of Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is a common clinical disease associated with upper gastrointestinal motility disorders. Recently, with improvements in living standards and changes in lifestyle and dietary habits, the incidence of GERD has been increasing yearly. However, the mechanism of GERD has not been fully elucidated due to its complex pathogenesis, and this had led to unsatisfactory therapeutic outcomes. Currently, the occurrence and development of GERD involve multiple factors. Its pathogenesis is mainly thought to be related to factors, such as lower esophageal sphincter pressure, transient lower esophageal sphincter relaxation, crural diaphragmatic dysfunction, hiatus hernia, and impaired esophageal clearance. Therefore, explaining the pathogenesis of GERD more clearly and systematically, exploring potential and effective therapeutic targets, and choosing the best treatment methods have gradually become the focus of scholars' attention. Herein, we reviewed current advancements in the dynamic mechanism of GERD to better counsel patients on possible treatment options.
