Tumor margin dissection was implemented in accordance with an updated neuro-navigation system and iMRI.
The major problems for the spreading of laparoscopic pancreatoduodenectomy are the dissection of retroperitoneal margin, the complicated reconstruction phase (further complicated by laparoscopic instruments), the length of operating time, and the lack of scientifically proved advantages compared to the conventional open technique.
The UNIPLATE was developed to improve operative times and limit dissection at the lateral margins of the vertebral bodies.
Anterior radical vulvectomy without inguinal lymph node dissection was performed with margins of at least 2 cm from the well defined lesion.
In the later Tertiary, uplift of the plateau that covers much of the SWBP led to erosion and dissection of the plateau margins and the creation of a more edaphically-complex landscape.
High-proliferative activity (>50%) is related to an elevated recurrence risk after surgery in patients with stage I tumours, making Ki-67 a potentially useful marker for patients in need of more extensive treatment (ie surgery with more extensive margins, neck dissection and postoperative radiotherapy).
Pathologically, the fractioned specimen involved moderately differentiated tubular adenocarcinoma invading the subserosal layer with positive margin of the dissection plane.
For patients with positive margins at the primary site at the time of TORS, an attempt can be made at the time of neck dissection to clear the positive margin transorally.
Abscess drainage was performed by two parallel incisions of the skin at 2 cm and 4 cm from the costal margin, followed by dissection of the subcutaneous tissue and the fascia of each flank, directly over each abscess at the point of greatest fluctuation.
The greater hospital resource use, costs, and complication rates associated with oncologic surgical resections relative to benign indications could be attributed to several differences in the surgical techniques required, extended tissue resection for adequate margins, lymph node dissection for staging, and/or the resection of ancillary tissues [13 15].
