RESUMO

Objective A percutaneous cholecystostomy (PC) is a suitable option for treating acutely inflamed gallbladders. Its use has been postulated before for treating acute cholecystitis (AC), especially in elderly populations. The primary aim of our study is to analyze and present the positive results of PC as a bridge to laparoscopic cholecystectomy. Methods All patients who underwent PC at our hospital, Princess Royal University Hospital, King's College Hospital NHS Foundation Trust, London, GBR, from October 2020 were reviewed using a retrospective approach. Results Our study comprises 123 patients, with 72 females (58.5%) and 51 males (41.4%). In our study, many patients had significant comorbidities, and some of them were categorized as high-risk due to their frailty and medical conditions. The majority of the patients were in American Society of Anaesthesiologists' (ASA) groups II and III (45, 61), respectively. Though hospital stays can depend on variable factors, in our experience, the mean hospital length of stay was 12.7 days. In our study, 119 patients (96.8%) had the procedure through the interventional radiological approach, while only four patients had it through the laparoscopic approach. The transhepatic route for drainage was more commonly practiced at our center and was used in 108 patients. At the time of writing this article, 54 patients have already had a laparoscopic cholecystectomy (LC) done as an interval procedure after surpassing the acute attack of cholecystitis, while 42 patients are still awaiting their surgical procedure. Conclusion Our results show that PC is a viable option, especially in cases of AC that are not responding to conservative treatments. Our study has shown low complications and conversion rates after PC. We believe PC is a safe and effective tool for managing severe and refractory cases of AC.

RESUMO

OBJECTIVES: The purpose of this study was to quantify contrast-enhanced ultrasound enhancement of focal fatty sparing (FFS) and focal fatty infiltration (FFI) and compare it with adjacent liver parenchyma. METHODS: This was a retrospective observational study yielding 42 cases in the last 4 years. Inclusion criteria were a focal liver lesion, adequate video availability, and an established diagnosis of FFS or FFI based on clinical or imaging follow-up or a second modality. Contrast-enhanced ultrasound examinations were performed with a standard low-mechanical index technique. Commercially available software calculated quantitative parameters for a focal liver lesion and a reference area of liver parenchyma, producing relative indices. RESULTS: In total, 42 patients were analyzed (19 male) with a median age of 18 (interquartile range, 42) years and a median lesion diameter of 30 (interquartile range, 16) mm. The cohort included 26 with FFS and 16 with FFI. Subjectively assessed, 27% of FFS and 25% of FFI were hypoenhancing in the arterial phase, and 73% of FFS and 75% of FFI were isoenhancing. In the venous and delayed phases, all lesions were isoenhancing. The peak enhancement (P = .001), wash-in area under the curve (P < .01), wash-in rate (P = .023), and wash-in perfusion index (P = .001) were significantly lower in FFS compared with adjacent parenchyma but not the mean transit time. In the FFI subgroup, no significant difference was detected. Comparing relative parameters, only the wash-in rate was significantly (P = .049) lower in FFS than FFI. The mean follow-up was 2.8 years. CONCLUSIONS: Focal fatty sparing shows significantly lower and slower enhancement than the liver parenchyma, whereas FFI enhances identically. Focal fatty sparing had a significantly slower enhancement than FFI.
