Ligamentum teres augmentation (LTA) for hiatal hernia repair after minimally invasive esophageal resection: a new use for an old structure.

ABSTRACT:

Purpose

Hiatal hernias with intrathoracic migration of the intestines are serious complications after minimally invasive esophageal resection with gastric sleeve conduit. High recurrence rates have been reported for standard suture hiatoplasties. Additional mesh reinforcement is not generally recommended due to the serious risk of endangering the gastric sleeve. We propose a safe, simple, and effective method to close the hiatal defect with the ligamentum teres.

Methods

After laparoscopic repositioning the migrated intestines, the ligamentum teres is dissected from the ligamentum falciforme and the anterior abdominal wall. It is then positioned behind the left lobe of the liver and swung toward the hiatal orifice. Across the anterior aspect of the hiatal defect it is semi-circularly fixated with non-absorbable sutures. Care should be taken not to endanger the blood supply of the gastric sleeve.

Results

We have used this technique for a total of 6 patients with hiatal hernias after hybrid minimally invasive esophageal resection in the elective (n = 4) and emergency setting (n = 2). No intraoperative or postoperative complications have been observed. No recurrence has been reported for 3 patients after 3 months.

Conclusion

Primary suture hiatoplasties for hiatal hernias after minimally invasive esophageal resection can be technically challenging, and high postoperative recurrence rates are reported. An alternative, safe method is needed to close the hiatal defect. Our promising preliminary experience should stimulate further studies regarding the durability and efficacy of using the ligamentum teres hepatis to cover the hiatal defect.

Project description:PurposeTo systematically review the literature to better understand the current indications for ligamentum teres reconstruction (LTR), current graft and acetabular fixation options used, patient-reported outcomes after LTR, and incidence of complications and reoperations after LTR.MethodsA systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. All literature related to LTR published prior to July 2020 was identified. The inclusion criteria consisted of investigations reporting on human patients with pathology of the ligamentum teres who underwent LTR, including mentions of the indications, graft type, acetabular fixation method, postoperative patient-reported outcome scores, and incidence of complications and reoperations.ResultsSeven studies comprising 26 patients (28 hips) were included. The most commonly reported indication for LTR was persistent pain and instability after failed prior hip arthroscopy (68%, 19 of 28 hips). The mean postoperative modified Harris Hip Score, Non-arthritic Hip Score, and visual analog scale score all showed improvement when compared with preoperative values. A total of 2 complications occurred. Complication rates ranged from 0% to 100% in included case reports and 0% to 11% in included case series. A total of 9 reoperations were performed. Reoperation rates ranged from 0% to 100% for case reports and 18% to 100% for case series. Reoperation rates ranged from 33% to 100% in studies with patients receiving acetabular fixation using anchors versus 0% to 22% in studies performing LTR with buttons. Reoperation rates in athletic patients and patients with Ehlers-Danlos syndrome ranged from 0% to 100% and 0% to 50%, respectively.ConclusionsThe main indication for LTR was persistent hip or groin pain and instability after a prior hip arthroscopy. The short-term postoperative modified Harris Hip Score, Non-arthritic Hip Score, and visual analog scale score after LTR showed favorable outcomes. However, reoperations after LTR were not uncommon.Level of evidenceLevel V, systematic review of Level IV and V studies.

Project description:BackgroundGiant hiatal hernias are more common in older patients and can significantly reduce their quality of life. However, open surgery for patients of advanced age is thought to be associated with high morbidity and mortality. The aim of this retrospective study was to evaluate the safety of laparoscopic giant hiatal hernia repair for elderly patients as compared to younger patients.MethodsFrom January 2015 to January 2020, 152 consecutive patients underwent laparoscopic mesh repair of giant hiatal hernia. Two cases of missing follow up were excluded. Patients were divided into an elderly group (N=62, age ≥75) and a younger group (N=88, age <75). Interrupted non-absorbable suture was applied for crus closure and as an additional reinforcement, the mesh was fixed with absorbable tacks or medical glue. Procedure-related complications, score-based variation tendency of symptoms, gastrointestinal quality of life index (GIQLI), mortality, recurrence rate, hemoglobin, and the use of PPI were investigated.ResultsAll patients underwent the procedure uneventfully. Dor fundoplication was used in 39 patients (62.9%) in the elderly group and 44 (50.0%) in the younger group and no case was converted to open. While the elderly group had a significantly higher percentage of ASA Class level 3 and cardiovascular and cerebrovascular diseases as compared to the younger group, the two groups had similar operative times, intraoperative blood loss, and percentage of intrathoracic stomach. Elderly group patients tended to have higher perioperative complications including pneumonia (3.2%) and atelectasis (3.2%) without statistical significance, as well as transfer to the intensive care unit compared, to younger patients (9.7% vs. 3.2%; P=0.144). The mean post-operative hospital stay was also significantly shorter in the younger group (2.8 days) compared with the elderly group (3.5 days; P=0.001). There was no mortality, recurrence, mesh-related complications such as visceral erosion, adhesion, or severe dysphagia during follow up in the two groups, and both groups demonstrated significant improvement in GIQLI scores and hemoglobin. The percentage of patients who needed PPI was also reduced in both groups.ConclusionsLaparoscopic mesh repair of giant hiatal hernia for elderly patients is safe and effective when performed at experienced centers.
