Cosmetic appearance is a major concern for living donors. However, little is known about the impact of a surgical scar on body image changes in living liver donors. The aim of this study was to identify potential factors that cause displeasing upper midline incision scar, and to evaluate the overall satisfaction regarding body image and scarring after living donor hepatectomy. Donors who underwent right lobe hepatectomy were recruited. Exclusion criteria included reoperation, refusal to participate, and lost follow-up. All donors were invited to complete the Vancouver Scar Scale (VSS) and the body image questionnaire. According to the VSS results of upper midline incision scar, donors were divided into 2 groups: good scarring group (VSS ≤4) and bad scarring group (VSS >4). we compared the clinical outcomes, including the demographics, preoperation, intraoperation, and postoperation variables. The study also analyzed the results of the body image questionnaire. The proportion of male donors was 48.9%. The bad scarring group consisted of 63% of the donors. On multivariate analysis, being a male donor was found to be an independent predictor of a cosmetically displeasing upper midline incision scar with statistical significance. The results of body image questionnaires, there were significant differences in cosmetic score and confidence score among the 2 groups. The upper midline incision and male donors have higher rates of scarring in comparison with the transverse incision and female donors. Donors who reported having a higher satisfaction with their scar appearance usually had more self-confidence. However, the body image won’t be affected. Medical staff should encourage donors to take active participation in wound care and continuously observe the impact of surgical scars on psychological changes in living liver donors.

The purpose of this study is to compute the cost efficiency of international tourist hotels ( ITHs) in Taiwan and analyze how regional environmental quality affects cost efficiency. The study collects a variety of operating data of international tourist hotels in Taiwan between 1998 and 2009 from the Annual Tourist Hotels Operational Analysis Report, as published by the Tourism Bureau. The data of regional environmental quality are collected from the Taiwan Environment Data Warehouse. This study first uses data envelopment analysis ( DEA) for computing cost efficiency, and then applies the truncated regression to investigate the impact of environmental indicators on cost efficiency. Namely, it is a two-stage DEA-regression method. The empirical results indicate that the density of pungent air pollutants, such as O 3 and SO 2 , have significantly negative impacts on the cost efficiency of ITHs in Taiwan. However, the high volume of waste disposal and low recycling rate reflect a higher business activity intensity in a region, which positively enhances ITHs' cost efficiency.

Background Early hepatic artery (HA) thrombosis and primary graft failure contribute greatly to the mortality of patients after liver transplantation. Herein, we present the treatment of intimal injury of HA by intraoperative fluorescence vascular stenting. Methods A sample of 471 patients receiving liver transplantations underwent arterial anastomosis. Six patients (1.3%) were found to have early HA thrombosis. Two patients had thrombi that were impenetrable with a guide wire. Intimal injury on both the graft and the donor sides of the HA was found after thrombectomy. We performed anastomosis between unhealthy graft vessels and healthy recipient vessels. Intraoperative angiography was done immediately because of the guide wire being easier to insert through a fresh thrombus, and a long endovascular stent was inserted to bypass the injured vessels. Results The proper HA was reconstructed under microscopy. Three days after reconstruction, an angioplasty showed no dissection, stenosis, or pseudoaneurysm of the HA. Unexpectedly, these 2 patients survived well with acceptable graft functionality, one based on a 32-month follow-up and the other based on a 2-month follow-up. Conclusion Anastomosis of the intimally injured graft artery followed by immediate endovascular angioplasty with stenting to bypass the injury zone is an efficacious and tolerable procedure.

Background:The aims of this study were to investigate if recipient artery choice in right lobe living donor liver transplant affects postoperative complications and discuss solutions accordingly. Methods: Three hundred fourteen right lobe living donor liver transplantation patients were divided into 2 groups: 163 patients using right hepatic artery as the recipient vessel and 151 patients using left hepatic artery as the recipient vessel. Cases involving 2 recipient blood vessels or the use of other blood vessels as recipient vessels were excluded. Results: Overall vascular embolism rate in both groups was 1.3%, and our complication rate was lower than those in previous studies. There was no significant difference in complication rate between the groups, but a significant difference in recipient/donor artery size ratio was noted. Conclusions: Although left hepatic artery's anatomical position makes it less affected by bile duct anastomosis and thus fewer postoperative complications, we believe that the ratio of the donor-recipient blood vessel size and the length of the anastomosis vessel stumps are the key factors that affect the outcome of the vascular anastomosis.
