Abstract Background Para-conduit hernia (PCH) formation is a rare and late complication of oesophagectomy that is associated with high risk morbidity. Minimally invasive oesophagectomy is associated with increased incidence of PCHs when compared to open or trans-hiatal oesophagectomies. Various techniques to repair PCHs including mesh repair, anterior/posterior hiatal suture repairs or even careful 360 degree repairs have been described in the literature1,2. But the risk of recurrence of PCH still remains high. We describe a unique laparoscopic technique which we believe to be associated with reduced risk of recurrence of PCH post-surgical repair. Method We present 4 cases of symptomatic PCH repairs performed laparoscopically. In this unique technique the contents of the sac is reduced and the hiatus is repaired anteriorly with interrupted ethibond sutures. The left lobe of the liver is mobilised and glued to the greater curve omentum along the conduit and the hiatus. This latter step is an additional way of preventing intraabdominal contents from entering the mediastinum. Data was collected retrospectively to include: patient demographics, details of original MIO surgery, pre-op imaging and details of the presenting symptoms with PCH including imaging, operative details and all available follow up. Results Between January 2022 and July 2024, 4 patients underwent laparoscopic repair of paraconduit hernia within 1-2 years post MIO. 3 were male and 1 female aged between 56-71 years. 3 of the procedures were performed electively and one as an emergency. All presented with symptomatic paraconduit hernias and managed with surgery using the technique described above. We present a video of laparoscopic repair as described. Conclusion We report a case series of 4 patients presenting with symptomatic PCH that were managed safely with a unique laparoscopic technique using suture repair and left liver lobe mobilisation to prevent recurrence of PCH.
