Surgical Outcomes after Laparoscopic Repairs of Para-colostomy Hernia and Para-ileal-conduit Hernia: A Comparative Study.

Objectives: The aim of the study was to investigate the differences in clinical characteristics and surgical outcomes between para-colostomy hernia (PCH) and para-ileal-conduit hernia (PICH) after laparoscopic repairs.
Methods: We retrospectively analyzed data from 41 laparoscopic parastomal hernia repairs performed at the Jikei University Daisan Hospital between June 2012 and September 2023. The data were divided into PCH (n=31) and PICH (n=10) groups and compared.
Results: The comparison of patient backgrounds and hernia characteristics showed no significant differences between PCH and PICH groups. Surgical procedures included laparoscopic Sugarbaker repair (LSB) for PCH (29 cases) and PICH (8 cases), and endoscopic Pauli repair (ePauli) for both PCH (2 cases) and PICH (2 cases). Intraoperative findings indicated a significantly higher rate of severe intra-abdominal adhesions (Zühlke index III/IV) in the PICH group (60%) compared to the PCH group (23%) (p=0.0485). The median operation time was significantly longer for PICH (223 [120-423] minutes) than for PCH (158 [48-386] minutes) (p=0.0467). Perioperative complications occurred in 1 PCH case (3%) and 2 PICH cases (20%), with no significant difference in postoperative hospital stay (9 [4-19] vs. 9 [6-14] days). With the follow-up period of 57 [2-110] months for PCH and 52 [20-104] months for PICH, recurrence was observed in 4 PCH cases (12%) but not statistically significant.
Conclusions: The comparison of PCH and PICH suggests that PICH is associated with more severe intra-abdominal adhesions and longer operation times, indicating higher operative difficulty. Therefore, it would be advisable to discuss the surgical outcomes of repair for these stomas separately.
