Abstract
BACKGROUND During left lateral section (LLS) resection for live liver donation, the vascular inflow and the bile drainage of segment 4 (S4) are compromised. We investigated the long-term changes of S4 after donation and their potential prognostic impact on living liver donors. MATERIALS AND METHODS This was a retrospective analysis of 42 consecutive left lateral (LLS, S2/3) liver resections for living donation. RESULTS There were 25 female and 17 male donors. Median age was 33 y and median body mass index was 26. Median LLS, S2/3, volume was 262 cc, and median sS4 volume was 160 cc. Complications were encountered in three donors (7%). An independent extrahepatic S4 artery (S4A) (with a proximal left heptic artery or a right hepatic artery origin) was identified in 41% of the donors. Ligation of the independent S4A was not associated with the rate of post resection liver dysfunction, complications, or the degree of S4 atrophy. Having a dominant S4 portal triad pedicle feeding the right anterior sectors, segment 5/8, of the liver was associated with increased parenchymal damage as evidenced by a higher peak of alanine aminotransferase but was not associated with postoperative complications. The median degree of atrophy of S4 at 1 y post donation as noted on imaging was 66%. The presence of a dominant S4 portal triad pedicle and the peak alanine aminotransferase early postoperatively were both predictors of the degree of S4 atrophy post donation. CONCLUSIONS The presence of an independent S4A or dominant S4 portal triad pedicle feeding the liver right anterior sectors, segment 5/8, should not be a contraindication for left lateral segment living donation.

Abstract
Objective: Optimal incision for major hepatectomy remains controversial. In this study, we described our experience with a limited upper midline incision (UMI) for major hepatectomy. The objective was to analyze the feasibility and safety of UMI in major hepatectomy.
Material and Methods: Fifty-seven consecutive patients who underwent major hepatectomies performed via an UMI were compared to a control group of 36 patients who underwent major hepatectomies with a conventional incision (CI).
Results: In 85% of the patients, the indication was malignancy, with a median tumor size of 6 cm. Fifty-three percent of the patients had underlying chronic liver disease, and liver fibrosis was found in 61% of the patients. Ninteen percent of the patients had previous upper abdominal surgery. Twenty- six patients underwent left hepatectomy, 20 patients had right hepatectomy and 11 patients trisegmentectomy. Additional combined surgical proce- dures were performed in 42% of the patients. Median operative time was 323 minutes, estimated blood loss was 500 ml, and median post-operative hospital stay was seven days. Surgical complications occurred in 22 patients (39%). 5-year overall survival was 67%. When compared with the control group with CI, patients with UMI had no statistical difference on operative time, estimated blood loss, length of hospital stay, complication rate, and overall survival.
Conclusion: Major hepatectomies can be safely performed through UMI. This approach should be considered as a reasonable option in addition to conventional and laparoscopic approaches for major hepatectomies.

A comparative study of portal vein embolization versus radiation lobectomy with Yttrium-90 micropheres in preparation for liver resection for initially unresectable hepatocellular carcinoma.

Abstract
BACKGROUND Portal vein embolization before liver resection is considered the therapy of choice for patients with inadequate future liver remnants. The concept of radioembolization with Yttrium-90 to achieve the same goal has limited data. METHODS We retrospectively compared patients who underwent portal vein embolization and Yttrium-90 lobectomy before resection of hepatocellular carcinoma in patients with chronic liver disease. RESULTS Seventy-three patients underwent portal vein embolization and 22 patients underwent Yttrium-90. Forty-seven percent of patients before portal vein embolization required additional procedures for tumor control, and 27% of patients after Yttrium-90 required additional procedure to mainly induce further hypertrophy. Both therapies achieved the goal of future liver remnants >40%, but the degree of hypertrophy was significantly higher in Yttrium-90 patients (63% for Yttrium-90, 36% for portal vein embolization, P < .01). Tumor response was significantly better with Yttrium-90, achieving complete response in 50% of patients. Resectability rate was higher after portal vein embolization (85% for portal vein embolization, 64% for Yttrium-90, P = .03). Tumor progression was the most common reason precluding surgery. Complete tumor control was the reason not to pursue surgery in 18% of patients after Yttrium-90. CONCLUSION Both preoperative portal vein embolization and Yttrium-90, increases liver resectability rates by inducing hypertrophy of future liver remnants in patients with hepatocellular carcinoma and chronic liver disease. Yttrium-90 lobectomy achieved better tumor control and provided more time to assess therapy response, optimizing the indication for surgery.
