Laparoscopic repair of hiatal hernia

Laparoscopic Large Hiatal Hernia Repair With RefluxStop: Outcomes of Six Months Follow-up in Thirty Patients

OBJECTIVE

The antireflux surgical technique with the RefluxStop device is one of the latest approaches to treating patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the safety and feasibility of laparoscopic hiatal hernia (HH) repair with the RefluxStop device in patients with GERD and concurrent large HH (≥4 cm).

PATIENTS AND METHODS

A retrospective chart review was performed for the first 30 patients with a large HH who consented and underwent HH surgery with the RefluxStop device. The operative technique and outcomes were evaluated to assess safety and feasibility, HH recurrence, dysphagia, and patient satisfaction.

RESULTS

Between May 2020 and April 2022, 30 patients underwent laparoscopic HH repair with the RefluxStop device. All patients had typical symptoms of GERD, such as heartburn and regurgitation, and 15 patients (50%) had preoperative dysphagia. Median HH size was 5 cm (interquartile range, 4 to 5). Median operating time was 56 minutes (interquartile range, 52 to 63), with no intra and postoperative complications related to the device. One patient required laparotomy due to adhesions and associated bleeding when accessing the abdomen. All patients had postoperative imaging (video fluoroscopy) on postoperative day 1 and at 3 months, confirming the correct location of the RefluxStop device. One patient (3.3%) needed postoperative balloon dilatation due to severe dysphagia. Reflux symptoms (heartburn and acid regurgitation) resolved significantly in all patients ( P < 0.001) at 6 months. One episode of recurrence of HH (3.3%) occurred during the follow-up period of 6 months.

CONCLUSION

This study demonstrates the short-term safety and feasibility of laparoscopic HH repair with the RefluxStop device in patients with large HH, with a low rate of postoperative dysphagia and subsequent improvement or resolution of reflux symptoms in all patients.

Continuously sutured versus linear-stapled anastomosis in robot-assisted hybrid Ivor Lewis esophageal surgery following neoadjuvant chemoradiotherapy: a single-center cohort study

BACKGROUND

Esophageal cancer surgery is technically highly demanding. During the past decade robot-assisted surgery has successfully been introduced in esophageal cancer treatment. Various techniques are being evaluated in different centers. In particular, advantages and disadvantages of continuously sutured (COSU) or linear-stapled (LIST) gastroesophageal anastomoses are debated. Here, we comparatively analyzed perioperative morbidities and short-term outcomes in patients undergoing hybrid robot-assisted esophageal surgery following neoadjuvant chemoradiotherapy (nCRT), with COSU or LIST anastomoses in a single center.

METHODS

Following standardized, effective, nCRT, 53 patients underwent a hybrid Ivor Lewis robot-assisted esophagectomy with COSU (n = 32) or LIST (n = 21) gastroesophageal anastomoses. Study endpoints were intra- and postoperative complications, in-hospital morbidity and mortality. Duration of operation, intensive care unit (ICU) and overall hospital stay were also evaluated. Furthermore, rates of rehospitalization, endoscopies, anastomotic stenosis and recurrence were assessed in a 90-day follow-up.

RESULTS

Demographics, ASA scores and tumor characteristics were comparable in the two groups. Median duration of operation was similar in patients with COSU and LIST anastomosis (467 vs. 453 min, IQR 420-521 vs. 416-469, p = 0.0611). Major complications were observed in 4/32 (12.5%) and 4/21 (19%) patients with COSU or LIST anastomosis, respectively (p = 0.697). Anastomotic leakage was observed in 3/32 (9.3%) and 2/21 (9.5%) (p = 1.0) patients with COSU or LIST anastomosis, respectively. Pleural empyema occurred in 1/32 (3.1%) and 2/21 (9.5%) (p = 0.555) patients, respectively. Mortality was similar in the two groups (1/32, 3.1% and 1/21, 4.7%, p = 1.0). Median ICU stay did not differ in patients with COSU or LIST anastomosis (p = 0.255), whereas a slightly, but significantly (p = 0.0393) shorter overall hospital stay was observed for COSU, as compared to LIST cohort (median: 20 vs. 21 days, IQR 17-22 vs. 18-28).

CONCLUSIONS

COSU is not inferior to LIST in the performance of gastroesophageal anastomosis in hybrid Ivor Lewis operations following nCRT.

Preoperative calculation of angles of vision and working area in laparoscopic surgery to treat a giant hiatal hernia

BACKGROUND

Giant hiatal hernias still pose a major challenge to digestive surgeons, and their repair is sometimes a highly complex task. This is usually performed by laparoscopy, while the role of the thoracoscopic approach has yet to be clearly defined.

AIM

To preoperatively detect patients with a giant hiatal hernia in whom it would not be safe to perform laparoscopic surgery and who, therefore, would be candidates for a thoracoscopic approach.

METHODS

In the present study, using imaging test we preoperatively simulate the field of vision of the camera and the working area (instrumental access) that can be obtained in each patient when the laparoscopic approach is used.

RESULTS

From data obtained, we can calculate the access angles that will be obtained in a preoperative computerised axial tomography coronal section, according to the location of the trocar. We also provide the formula for performing the angle calculations If the trocars are placed in loss common situations, thus enabling us to determine the visibility and manoeuvrability for any position of the trocars.

CONCLUSION

The working area determines the cases in which we can operate safely and those in which certain areas of the hernia cannot be accessed, which is when the thoracoscopic approach would be safer.

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.
