Short-term results after laparoscopic repair of giant hiatal hernias with pledgeted sutures: a retrospective analysis

Robotic hiatal hernia repair without mesh

Background

Newer minimally invasive techniques have supplanted laparotomy and thoracotomy for management of hiatal hernias. Limited data exists on outcomes after robotic hiatal hernia repair without mesh despite the increasing popularity of this approach. We report our high-volume experience with durable robotic hiatal hernia repair with gastric fundoplication without mesh.

Methods

A retrospective review was conducted on patients with type I-IV hiatal hernias who underwent an elective robotic-assisted repair from 2016 to 2019 using a novel technique of approximating the hiatus with running barbed absorbable (V-locTM) suture and securing it with interrupted silk sutures. Main outcomes included length of stay, readmission rate, and recurrence rate.

Results

A total of 144 patients were reviewed. The average age of the patient was 61 years. Most of the patients were female [95 females (66%) to 49 males], and the average body mass index (BMI) was 29.96 kg/m2. The average operating time was 173 minutes (standard deviation 62 minutes). The average length of stay in the hospital was 2 days, and 89% of patients went home within the first 3 days. Ten patients (6.9%) were readmitted within 30 days, there were no mortalities in 30 days, and there were 6 (4.2%) recurrences on follow up requiring reoperation.

Conclusions

Elective robotic hiatal hernia repair with fundoplication and primary closure of the hiatus with V-locTM and nonabsorbable suture without mesh is safe and effective. The robotic approach has similar operative times, lengths of stay, and complications compared to nationally published data on laparoscopic hiatal hernia repairs.

Intraoperative endomanometric laparoscopic Nissen fundoplication improves postoperative outcomes in large sliding hiatus hernias with severe gastroesophageal reflux disease: a retrospective cohort study

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is the gold standard surgical intervention for gastroesophageal reflux disease (GERD). LNF can be followed by recurrent symptoms or complications affecting patient satisfaction. The aim of this study is to assess the value of the intraoperative endomanometric evaluation of esophagogastric competence and pressure combined with LNF in patients with large sliding hiatus hernia (>5 cm) with severe GERD (DeMeester score >100).

MATERIALS AND METHODS

This is a retrospective, multicenter cohort study. Baseline characteristics, postoperative dysphagia and gas bloat syndrome, recurrent symptoms, and satisfaction were collected from a prospectively maintained database. Outcomes analyzed included recurrent reflux symptoms, postoperative side effects, and satisfaction with surgery.

RESULTS

Three hundred sixty patients were stratified into endomanometric LNF (180 patients, LNF+) and LNF alone (180 patients, LNF). Recurrent heartburn (3.9 vs. 8.3%) and recurrent regurgitation (2.2 vs. 5%) showed a lower incidence in the LNF+ group ( P =0.012). Postoperative score III recurrent heartburn and score III regurgitations occurred in 0 vs. 3.3% and 0 vs. 2.8% cases in the LNF+ and LNF groups, respectively ( P =0.005). Postoperative persistent dysphagia and gas bloat syndrome occurred in 1.75 vs. 5.6% and 0 vs. 3.9% of patients ( P =0.001). Score III postoperative persistent dysphagia was 0 vs. 2.8% in the two groups ( P =0.007). There was no redo surgery for dysphagia after LNF+. Patient satisfaction at the end of the study was 93.3 vs. 86.7% in both cohorts, respectively ( P =0.05).

CONCLUSIONS

Intraoperative high-resolution manometry and endoscopic were feasible in all patients, and the outcomes were favorable from an effectiveness and safety standpoint.

Hiatal hernia recurrences after laparoscopic surgery: exploring the optimal technique

INTRODUCTION

The recurrence rate of hiatal hernia (HH) after laparoscopic surgery with crural repair and Nissen or Toupet fundoplication is high (< 25-42%). HH repair can be reinforced with additional anterior sutures, vertical mesh strips (VMS) or mesh placement but the effect in the long-term (> 1 year) is still unclear. We determined the recurrence rate of HH after surgery and established whether the use of reinforcement techniques could reduce long-term recurrence rates.

METHODS

In this retrospective cohort study patients were included if they underwent a laparoscopic fundoplication in this hospital between 2012 and 2019. HH was measured with computed tomography and baseline patient characteristics and surgical details were collected. Primary outcomes were recurrence of symptoms and re-intervention, secondary outcome was effect of surgical reinforcement techniques. Statistical analyses comprised chi-square tests, Mann-Whitney U tests and uni- and multivariable logistic regression analyses.

RESULTS

In total, 307 patients were included, 206 women and 101 men. During primary surgery, 208 patients underwent a Toupet fundoplication and 97 patients underwent a Nissen fundoplication. Reinforcements consisted of anterior sutures in 132 patients, VMS in 89 patients and mesh in 17 patients. After primary surgery, recurrence of HH was diagnostically confirmed in 64 patients (20.8%). Use of VMS during primary surgery was significantly associated with fewer recurrences (OR = 0.34, p = 0.048), corrected for confounding factors. Secondary surgery was performed in 54 patients (17.6%) and tertiary surgery in five patients (1.6%). Mesh and VMS were used more during secondary and tertiary surgery.

CONCLUSION

The recurrence rate among HH patients in this cohort study was 20.8% with a mean follow-up time of 6 years. Secondary surgery was performed in 17.6% of the patients. In future, the use of VMS might lead to fewer recurrences after primary laparoscopic repair of HH.

Surgical treatment of large and complicated hiatal hernias with the new resorbable mesh with hydrogel barrier (Phasix™ ST): a preliminary study

Evaluation of the efficacy and safety of the new monofilament fully resorbable mesh with hydrogel barrier (Phasix™ ST), for large and complex hiatal hernia repair. Between December 2017 and December 2020, 60 patients with large or complicated hiatal hernia were treated (40 robotic and 20 laparoscopic procedures). The mesh was placed after primary closure of the hiatal defect, in an onlay fashion around the esophagus, followed by 360^o fundoplication. Follow-up at 3, 6, 12, 18, 24 months from intervention included clinical evaluation and upper GI endoscopy. In cases of recurrence, radiologic survey and manometry were utilized. There were no conversions to open repair or significant postoperative incidents. Over a median follow-up of 21 months (range 3-36), no recurrences or mesh related complications were observed. From our early experience, Phasix™ ST mesh seems to be safe and effective for the reinforcement of crural defects in large and complex hiatal hernia.

Poor Gastric Emptying in Patients with Paraesophageal Hernias: Pyloroplasty, Per-Oral Pyloromyotomy, BoTox, or Wait and See?

Gastric emptying delay may be caused with both functional and anatomic derangements. Gastroparesis is suspected in patients presenting with certain foregut symptoms without anatomic obstruction. Data are still emerging regarding the best treatment of this condition. In cases where large paraesophageal hernias alter the upper gastrointestinal anatomy, it is difficult to know if gastroparesis also exists. Management of hiatal hernias is also still evolving, with various strategies to reduce recurrence being actively investigated. In this article, we present a systematic review of the existing literature around the management of gastroparesis and the management of paraesophageal hernias when they occur separately. In addition, since there are limited data to guide diagnosis and management of these conditions when they are suspected to coexist, we provide a rational strategy based on our own experience in patients with paraesophageal hernias who have symptoms or studies that raise suspicion for a coexisting functional disorder.

Transient delayed gastric emptying following laparoscopic Nissen fundoplication for gastroesophageal reflux disease

PURPOSE

Although laparoscopic Nissen fundoplication (LNF) is a kind of minimally invasive surgery, some transition time may still be required to allow the fundoplicated stomach to adapt to the new anatomical position. We observed transient delayed gastric emptying (DGE) post-LNF in our preliminary study. This study aimed to investigate the occurrence rate and development of transient DGE post-LNF.

METHODS

Patients who underwent LNF for gastroesophageal reflux disease (GERD) at our institution were recruited consecutively. They were treated with standardized LNF and prospectively followed up for 2 months. Proper diet guidance and/or pharmacologic therapy were given during these 2 months. GERD Health-Related Quality of Life (GERD-HRQL), DGE symptoms, and DGE status were evaluated preoperatively and postoperatively.

RESULTS

Fifty-one patients underwent LNF and completed a 2-month follow-up. LNF succeeded in all patients. Prior to LNF, no DGE was identified. At the 1-month follow-up, LNF led to a significant reduction in the GERD-HRQL total score but a significantly increased DGE score. Endoscopically, DGE was identified in forty-seven (n = 47, 92.2%) patients. At the 2-month follow-up, the GERD-HRQL scores continued to show decreases compared to the 1 month. The DGE score returned to the baseline value. Endoscopically, no DGE was identified in any patients (n = 0, 0.0%).

CONCLUSIONS

Transient DGE is a very common one-month post-LNF but can recover quickly in the second month following LNF.

[Planning and Design of a Prospective Randomised Multi-Centre Trial on the Repair of Large Hiatal Hernias with Sutures vs. Pledgeted Sutures vs. Absorbable Mesh]

BACKGROUND

The hernia recurrence rate after surgical treatment of large hiatal hernias is still very high. The optimal technique to reduce the recurrence rate is still under debate. The aim of this work is to clarify whether pledgeted reinforced sutures or a resorbable mesh can reduce the recurrence rate compared to hiatus closure with only sutures.

MATERIALS AND METHODS

An Austria-wide, multi-centre, prospective, randomised study was planned. The study protocol was prepared by the main test centre (University Clinic for General, Visceral and Thoracic Surgery, Paracelsus Medical University Salzburg). The study includes patients who are scheduled to undergo laparoscopic or robot-assisted surgery for a large symptomatic hiatal hernia. A large hiatal hernia is defined as > 5 cm in manometry or gastroscopy or at least ⅓ of the stomach lying intrathoracically. The primary study endpoint is defined as the hernia recurrence rate, objectively assessed by gastroscopy. After inclusion in the study, patients will be followed up for 6 months, 1 year, 3 years and 5 years after the operation, using standardised questionnaires and gastroscopy. The power calculation showed a requirement of 55 patients per group. Preoperative randomisation and data management are software-based.

RESULTS

The study approval by the leading ethics committee is currently pending and the study itself has been registered on ClinicalTrials.gov since October 2020. The Clinical Trials Registration Number is NCT04591860. Five clinics are participating in the study at the moment and all centres are actively enrolling patients. The duration of the study is set until January 2027.

CONCLUSION

This study is the world's first prospective randomised study that examines the value of pledgets and resorbable mesh to reduce the recurrence rate after treatment of large hiatal hernias. The results will help to find the optimal technique to close the hiatus of large hiatal hernias.

Reparación laparoscópica de hernia hiatal gigante

Introducción. La reparación laparoscópica es el estándar de tratamiento en hernia hiatal gigante. Sin embargo, a pesar de su baja morbilidad, la tasa de recurrencia sigue siendo alta. Nuestro objetivo fue describir los resultados de la reparación laparoscópica de hernia hiatal gigante, independientemente de la técnica de cruroplastia empleada. Métodos. Se llevó a cabo un estudio retrospectivo de pacientes llevados a reparación laparoscópica de hernia hiatal gigante en el periodo 2009-2017. Se analizaron los datos demográficos, la técnica quirúrgica, las complicaciones y la estancia hospitalaria. Se revisaron los resultados de la endoscopia, la radiografía de vías digestivas altas y la escala de síntomas GERD-HRQOL, obtenidos luego de un año de cirugía. Resultados. Se incluyeron 44 pacientes con un tamaño promedio de la hernia de 7 cm. Se practicó cruroplastia con sutura simple en 36,4 %, sutura más refuerzo con politetrafluoroetileno (PTFE) o dacrón, en 59,1 %, y se usó malla en 4,5 %. Hubo 12 complicaciones, la estancia hospitalaria promedio fue de 3,5 días y no hubo mortalidad. Se encontró recurrencia endoscópica o radiológica en 6/20 pacientes, todas pequeñas y asintomáticas. En 23 pacientes, la escala GERD-HRQOL reportó un valor promedio de 7,7 y 78 % de satisfacción. Solo un paciente requirió cirugía de revisión. Conclusión. El método preferido de reparación laparoscópica de la hernia hiatal gigante es la cruroplastia sin malla, técnica asociada a baja morbilidad y adecuado control de los síntomas. La tasa de recurrencia es similar a la reportada en la literatura. Se requieren estudios prospectivos con seguimiento completo a largo plazo para validar estos resultados.

Large paraesophageal hernia in elderly patients: Two case reports of laparoscopic posterior cruroplasty and anterior gastropexy

BACKGROUND

Paraesophageal hernia (PEH) is a rare form of hiatal hernia, which commonly occurs in elderly people. Although asymptomatic, it can be associated with severe life-threatening complications, such as gastric volvulus. Surgical treatment is reserved for symptomatic patients. Herein, we present two cases of complicated PEH that were treated with laparoscopic posterior cruroplasty and anterior gastropexy.

CASE SUMMARY

An 88-year old woman presented with epigastric pain, hematemesis and food intolerance for the last two days. Physical exam revealed mild abdominal distention. Chest X-ray showed a left thoracic opacity, and barium swallow images showed a mixed type III PEH. Abdominal CT-scan images confirmed the diagnosis of incomplete gastric volvulus. The patient underwent a laparoscopic hernia reduction with sac excision, posterior cruroplasty and anterior gastropexy with continuous barbed suturing. The postoperative course was uneventful, and follow-up showed complete resolution of her symptoms. A 91-year old patient was admitted for dyspnea and fever, with vomiting and food intolerance for the last 7 days. Physical exam revealed absent sounds on both lungs. Chest X-ray showed a large left opacity. CT-scan images revealed a giant PEH with complete gastric volvulus. The patient underwent emergency laparoscopic hernia reduction and sac excision, with re-inforced posterior cruroplasty, and anterior gastropexy with continuous barbed suturing. There were no surgical complications, but the patient died on the 4^th day postoperatively due to respiratory failure.

CONCLUSION

Early laparoscopic posterior cruroplasty and anterior gastropexy is a safe and effective surgical alternative for elderly patients with comorbidities, presenting with symptomatic PEH.
