Infant-to-infant whole liver transplantation (I2I-WLT) has been rarely performed in Korea. We analyze clinical sequences of our 7 cases of I2I-WLT and present evolution of surgical techniques to prevent PV stenosis.

A total of 7 cases of I2I-WLT were performed at our institution during last 13 years, which represented 0.1% of our LT volume. Patient perioperative profiles and clinical sequences were analyzed with focusing on portal vein (PV) complications.

Donor ages were 6-17 months and graft weights were 140-525 g. Recipient ages were 7-16 months and body weights were 6-10.1 kg and Primary diagnoses were biliary atresia in 6 and progressive familial intrahepatic cholestasis in 1. The first case underwent PV stenting 2 months after I2I-WLT, and underwent retransplantation 6 years later. The second case underwent intraoperative PV stenting, but died 32 days later. The third case underwent repeated PV dilatation. The fourth, fifth and seventh cases experienced no surgical complications, and PV reconstruction was performed using a side-to-side unification venoplasty technique. The sixth case had poor development of the PV system, so customized PV venoplasty was performed, but PV occlusion requiring PV stenting occurred. Early retransplantation was performed, but scanty PV flow was detected despite no obvious PV stenosis, resulting in graft failure. Serious PV complications developed in 4, but none experienced after adoption of side-to-side unification venoplasty.

As PV size in infant donors and recipients is very small, PV reconstruction in I2I-WLT requires specialized surgical techniques of side-to-side unification venoplasty.

Surgical resection for the treatment of multiple hepatocellular carcinomas (HCCs) is controversial. This study aimed to evaluate the clinical and oncological outcomes after liver resection in patients with multiple HCCs.

Clinicopathological and survival data of 187 patients who underwent curative resection for multiple HCCs between June 2004 and December 2016 at Asan Medical Center, Seoul, South Korea were retrospectively reviewed. The prognostic factors for recurrence and survival were identified using univariate and multivariate analyses.

Of the 187 patients, 153 (81.8%) had two nodules, 23 (12.3%) had three nodules, and 11 (5.9%) had more than three nodules. Multiple tumors were located in the ipsilateral lobe in 163 (87.2%) patients. Veliparib chemical structure Anatomical resection, non-anatomical resection, and both types of resections were performed in 81.3%, 8.0%, and 10.7% patients, respectively. Recurrence occurred in 133 (71.1%) patients, and the mean time to recurrence after surgery was 34.2 months. Independent risk factors for tumor recurrence in multivariate analyses were indocyanine green retention rate at 15 min ≥15%, preoperative alpha-fetoprotein level ≥400 ng/ml, and total tumor diameter ≥6 cm. The 1-, 3-, 5-, and 10-year disease-free survival rates were 94.1%, 81.7%, 69.7%, and 39.4%, respectively, and the 1-, 3-, 5-, and 10-year survival rates were 93.5%, 74.2%, 64.9%, and 38.8%, respectively.

Our experience shows that liver resection can be considered a first-line treatment option for selected patients with multiple HCCs who have well-preserved liver function.

Intrahepatic recurrence is frequent result after hepatectomy for hepatocellular carcinoma (HCC). We analyzed the clinical results of patients who had the intrahepatic recurrences of HCC after curative surgical resections.

From January 2009 to December 2016, 320 patients underwent curative surgical resection for HCC in department of Surgery, Korea Cancer Center Hospital. After surgical resection, 155 patients had suffered HCC recurrence during follow-up period. Among them, 122 patients had only intrahepatic recurrence initially, who were included in this retrospective study. We analyzed about the period of the recurrence after surgery, treatment methods for the recurred tumors, and poor prognostic factors for survival after intrahepatic recurrences.

Among the 122 patients, 83 patients had recurrence within 24 months after surgery. Thirty-eight patients underwent curative treatment for the recurred tumors (re-resection in 18, radiofrequency ablation in 20 patients). Non-curative treatments were performed in 77 patients (TACE in 68 patients, radiotherapy in 9 patients) and conservative management in 7 patients. Five-year survival rate of patients who underwent curative treatment is 86.4% (

≤0.001). Five-year survival rate of non-curative treatment is 55.7% (

≤0.001), conservative management is 0% (

=0.021). Among the clinical factors, non-curative treatment for recurred tumor, AFP level at the time of recurrence, size of recurred tumor were independent poor prognostic factors for survival after intrahepatic recurrences (

<0.001).

For the patients who had intrahepatic recurrent HCC after surgery, aggressive local treatment can improve the prognosis in selective cases. Further study is necessary to validate this retrospective investigation.

To evaluate our initial experience of bridging role of trans-arterial radio-embolization (TARE) before major hepatectomy for hepatocellular carcinoma (HCC) in risky patients with small expected remnant liver volume (ERLV).

We reviewed the data of patients with HCC who underwent major hepatectomy after TARE during the period between March and December 2017. Patients included had uni-lobar large HCC (＞5 cm) requiring major hepatectomy with small ERLV.

Five patients were included in our study. All patients were Child Pugh class A. A single session of TARE was applied in all patients. None developed any adverse events related to irradiation. The mean tumor size at baseline was 8.4 cm and 6.1 cm after TARE (

=0.077). The mean % of tumor shrinkage was 24.5%. ERLV improved from 354.6 ml at baseline to 500.8 ml after TARE (

=0.012). ERLV percentage improved from 27.2% at baseline to 38.1% after TARE (

=0.004). The mean % of ERLV was 39.5%. The mean interval time between TARE and resection was 99.6 days. Four patients (80%) underwent right hemi-hepatectomy and one patient (20%) underwent extended right hemi-hepatectomy.
