Background: Achieving complete cytoreduction of peritoneal surface malignancies (PSM) can be challenging. In most cases, delivery of heated intra-peritoneal chemotherapy (HIPEC) is straightforward. However, using the closed technique in some cases may be technically challenging; for example, in patients requiring abdominal closure using a large synthetic mesh. In cases where groin hernias are present, it is imperative to resect the hernia sac, since it may contain tumor deposits. In cases with major inguinal involvement where disease may spread out of the hernia sac or in cases where a hernia repair was performed while disease is present, inguinal perfusion should be considered.
Aim: To describe our experience with combined intra-peritoneal and inguinal perfusion of HIPEC following cytoreductive surgery.
Patients and Methods: This is a retrospective review of all patients who underwent cytoreductive surgery (CRS) and HIPEC at our institution. A prospectively maintained database containing data of patients treated by CRS and HIPEC (n=122) was reviewed. All patients with macroscopic inguinal involvement by PSM with complete cytoreduction perfused by HIPEC were included.
Results: We identified five cases who underwent CRS and combined intraperitoneal and inguinal perfusion after resection of large inguinal tumor deposits (n=4) or after a recent hernia repair with hernial sac involvement by mucinous adenocarcinoma (n=1). All five patients were successfully perfused using an additional outflow catheter placed in the groin.
Discussion: In cases of inguinal involvement by PSM, complete cytoreduction should be achieved and perfusion of the involved groin considered as it is feasible and safe.
