The Efficacy of PTGBD for Acute Cholecystitis Based on the Tokyo Guidelines 2018.

BACKGROUNDS

We usually performed percutaneous transhepatic gallbladder drainage (PTGBD) for moderate and severe acute cholecystitis (AC) prior to cholecystectomy. But, the validity of preoperative drainage for AC is still controversial. The aim of this study is to evaluate the efficacy and safety of PTGBD for moderate and severe AC, based on the Tokyo Guidelines 2018.

MATERIALS

Total of 146 AC patients from 2012 to 2017 were enrolled. Patients were classified in the grade of severity according to TG18, compared with PTGBD and non-PTGBD group. We retrospectively reviewed clinical backgrounds and laboratory data at admission. We evaluated surgical performances as the primary outcomes and recovery periods based on guidelines.

RESULTS

A total of 61 cases were moderate, and 18 cases were severe AC, and PTGBD were performed in 34 cases. For moderate AC, age, DM rate and ASA in PTGBD group were significantly higher than those in non-PTGBD group. Also, serum albumin and hemoglobin at admission were significantly lower in the PTGBD group. However, surgical outcomes were almost the same. For severe AC patients, laparoscopic cholecystectomy was performed safely in all of pre-operating drainage cases, while almost all of non-PTGBD cases underwent open laparotomy and needed transfusion for massive bleeding.

CONCLUSIONS

Preoperative PTGBD is a useful and safe procedure for AC patients with comorbidities, especially in severe AC cases. Treatment flowchart in TG18 can be feasible to make accurate prediction for surgically high-risk patients in AC.
