Long-term outcome of portomesenteric vein invasion and prognostic factors in pancreas head adenocarcinoma.
The purpose of this study was to clarify the post-operative prognosis of pancreatic head cancer with pathologic portal vein (PV) or superior mesenteric vein (SMV) invasion. ⋯ 34.8% of patients who underwent PV-SMV resection had no pathologic invasion. And PV-SMV resection did not increase the rate of severe complications and mortality. Furthermore, the prognosis for patients with pathologic PV-SMV invasion may be nearly the same as patients with no invasion. So, PV-SMV resection with reconstruction should be considered in pancreatic head cancer patients with suspected PV-SMV invasion.

Surgical mentors have helped trainees develop fulfilling and academically productive careers, while supervisors are formally assigned to impart skills and oversee training. This paper reviews the comparative roles of the supervisor and mentor and how they overlap, while exploring the impact of the 'unknown' mentor. While the supervisor's role in directing the student is formally recognized, the mentee will personally select a mentor who successfully models the career and life balance to which the mentee aspires. ⋯ Confusion between the two roles - mentor and supervisor - is due to their complementary nature as well as an overlap in roles. Both remain essential to the growth and development of the surgical trainee. The unknown mentor could give detached advice and guidance to the student, while acting as a positive role model.
