Abstract
Background
The aberrant left hepatic artery (ALHA) is an anatomic variation that may present an obstacle in laparoscopic antireflux procedures. Based on our experience, we addressed the following questions: How frequent is ALHA? When or why is it divided? What is the outcome in patients after division of the ALHA?
Methods
From a prospective collected database of 720 patients undergoing laparoscopic antireflux surgery, we collected the following information: presence of an ALHA, clinical data, diagnostic workup, operative reports, laboratory data, and follow-up data.
Results
In 57 patients (7.9%) (37 men and 20 women; mean age, 51 ± 15.7 years), an ALHA was reported. Hiatal dissection was impaired in 17 patients (29.8%), requiring division of the ALHA. In three patients (5.3%), the artery was injured during dissection; in one case (1.8%), it was divided because of ongoing bleeding. Ten of the divided ALHA (55.5%) were either of intermediate size or large. Mean operating time was 2.2 ± 0.8 h; mean blood loss was 63 ± 49 ml. Postoperative morbidity was 5.3% and mortality was 0%. None of the patients with divided hepatic arteries had postoperative symptoms related to impaired liver function. Postoperatively, two patients (11.7%) had transient elevated liver enzymes. At a mean follow-up of 28.5 ± 12.8 months, no specific complaints could be identified.
Conclusions
ALHA is not an uncommon finding in laparoscopic antireflux surgery and may be found in ≥8% of patients. Division may be required due to impaired view of the operating field or bleeding. Patients do not experience clinical complaints after division, but liver enzymes may be temporarily elevated.
