ABSTRACT
Objective To investigate the clinical effect of two-step percutaneous transhepatic choledochoscopic lithotomy (PTCSL) in the treatment of complex hepatolithiasis. Methods A retrospective analysis was performed for the clinical data of 118 patients with complex hepatolithiasis who were admitted to 3201 Hospital of Xi'an Jiaotong University Health Science Center from January 2018 to June 2020, and according to the surgical procedure, they were divided into PTCSL group with 60 patients and surgery group with 58 patients. All patients were followed up for half a year to 3 years via telephone and outpatient service. The two groups were compared in terms of general information, perioperative indicators (including time of operation, intraoperative blood loss, incision length, time to first flatus and time to first defecation after surgery, time to extraction of abdominal drainage tube, and length of hospital stay), changes in liver function and inflammatory indicators, postoperative complications (bile leakage, acute cholangitis, wound infection, and venous thrombosis of lower extremities), stone clearance rate and recurrence rate, and quality of life. The two-independent-samples t -test was used for comparison of continuous data between two groups; the paired t -test was used for comparison between different periods of time within group; the chi-square test was used for comparison of categorical data between two groups. Results Compared with the surgery group, the PTCSL group had significantly shorter time of operation, time to first flatus and time to first defecation after surgery, and time to extraction of abdominal drainage tube, a significantly lower intraoperative blood loss, and a significantly shorter incision length (all P < 0.05). On day 1 after surgery, both groups had significant reductions in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ( P < 0.05) and a significant increase in white blood cell count (WBC) ( P < 0.05), and the PTCSL group had significantly lower levels of ALT, AST, and WBC than the surgery group (all P < 0.05). Compared with the surgery group, the PTCSL group had significantly lower incidence rates of postoperative bile leakage (5.0% vs 17.2%, P < 0.05), acute cholangitis (3.3% vs 13.8%, P < 0.05), wound infection (1.7% vs 10.3%, P < 0.05), and venous thrombosis of lower extremities (1.7% vs 12.1%, P < 0.05). Compared with the surgery group, the PTCSL group had a significantly higher stone clearance rate (58.3% vs 37.9%, P < 0.05) and a significantly lower long-term stone recurrence rate (10.0% vs 20.7%, P < 0.05). The PTCSL group had significantly higher quality of life scores than the surgery group (all P < 0.05). Conclusion For the treatment of complex hepatolithiasis, two-step PTCSL can effectively remove stones, with the advantages of fast postoperative recovery, low recurrence rate and incidence rate of complications, and high quality of life, and therefore, it is an effective alternative surgical procedure.
ABSTRACT
Objective To investigate the clinical effect of percutaneous transhepatic drainage combined with sequential percutaneous nephroscopy for necrosectomy and drainage in the treatment of refractory liver abscess after transcatheter arterial embolization (TACE). Methods A retrospective analysis was performed for three patients with refractory liver abscess after TACE in The Affiliated 3201 Hospital of Xi'an Jiaotong University School of Medicine from January 2018 to December 2020, and among the three patients, one had the formation of liver abscess after TACE for hepatic metastases after pancreaticoduodenectomy, one had liver abscess after repeated TACE for massive hepatocellular carcinoma, and one had secondary liver abscess after TACE for traumatic hepatic rupture. All three patients received percutaneous transhepatic drainage and sequential percutaneous nephroscopy for the treatment of refractory liver abscess, and their specific treatment process was summarized. Results All three patients were diagnosed with refractory liver abscess based on CT, routine blood test, procalcitonin, blood culture, and clinical manifestation. Percutaneous transhepatic catheterization under the guidance of conventional ultrasonography or CT and effective antibiotics had an unsatisfactory therapeutic effect, and after sequential percutaneous nephroscopy was performed for necrosectomy and drainage, liver abscess was cured and the patients had good prognosis. Conclusion For refractory liver abscess after TACE, when routine puncture treatment has an unsatisfactory therapeutic effect or a patient cannot tolerate surgical operation, percutaneous transhepatic drainage combined with sequential percutaneous nephroscopy is safe and effective in the treatment of refractory liver abscess.
