FTP5.10 Predictors of re-intervention following index cholecystectomy

Abstract

Abstract Aim Index Cholecystectomy (IC) is safe and reduces patient morbidity. However, IC can be challenging due to inflammation of hepatocystic triangle, increasing the risk of postoperative complications. Study was conducted to evaluate factors influencing postoperative complications following IC. Method Retrospective review of consecutive IC performed as a primary procedure was carried out between February 2021 and July 2022 in our trust. Primary outcome was postoperative Grade 3 Clavien-Dindo (CDC) complication, in comparison to patients with uncomplicated recovery. Pre-operative factors including age, CRP, WBC, LFT, surgeon grade, modality (laparoscopic/open) and number of previous admissions were included for analysis. Categorical and continuous data were analysed using Chi-Square and Mann-Whitney-U tests respectively. P-value <0.05 was statistically significant. Results 100 IC were included. Most IC were consultant-led [80/100(80%)]. 11/100(11%) patients developed Grade 3 CDC complication; 4/100(4%) bile leak requiring ERCP and stent insertion, 3/100(3%) post-operative collection requiring radiological-assisted drainage, 2/100(2%) retained bile duct stones requiring ERCP, 1/100(1%) incision and drainage of port site seroma and 1/100(1%) biloma requiring laparoscopic washout. Re-intervention was common in older patients (61±18years vs 55±22years, p=0.04) and higher median peak CRP levels (312±178 vs 154±284, p=0.01). There were no differences in LFT parameters, number of previous admissions or timing of operation from day of admission between the two groups. Conclusion Age>65 and higher pre-operative CRP were associated with increased risk of postoperative procedural intervention. Larger prospective studies are needed to confirm these findings. Surgeons should consider these factors for consenting and risk assessment purposes.
