Background Complex procedures often have numerous acceptable approaches; it is unclear how surgical fellows choose between techniques. We used pancreaticoduodenectomy as a model to catalogue variability between surgeons and investigate factors that affect fellows' acquisition of techniques. Materials and methods Semistructured interviews and operative note analysis were conducted to determine techniques of 5 attending surgeons, and these data were mapped to identify variations. Identical interviews and questioning were completed with 4 fellowship graduates whose practice includes pancreaticoduodenectomy...

Background Preoperative localization of the parathyroid gland prior to a minimally invasive parathyroidectomy (MIP) is important because of varying locations of the parathyroid gland. Several methods have been described to localize the affected gland. One novel technique is the use of an iodine 125 (I-125) seed as a marker. The aim of this study is to evaluate the feasibility of using an I-125 seed in localizing the diseased parathyroid gland prior to MIP. Materials and methods This is a pilot study of 10 patients performed in the Amphia Hospital, the Netherlands...

Purpose To evaluate effectiveness of a novel hemostatic dissection tool in patients with congenital heart disease undergoing redo pericardiac dissections. Description This dissection tool employs ferromagnetic energy to cut and coagulate. The unit passes no electric current through the patient, thus eliminating cautery-induced dysrhythmias and electrical interference. Ferromagnetic dissection is precise and reduces thermal injury spread by as much as 90%. Evaluation We case matched 22 patients undergoing reoperation for congenital heart surgery by weight/operation...

Transanal, hybrid natural orifice translumenal endoscopic surgery (NOTES) and NOTES-assisted natural orifice specimen extraction techniques hold promise as leaders in the field of natural orifice surgery. We report the feasibility of a novel NOTES assisted technique for unlimited length, clean, endolumenal proctocolectomy in a porcine model. This technique is a modification of a transanal intussusception and pull-through procedure recently published by our group. Rectal mobilization was achieved laparoscopically; this was followed by a transanal recto-rectal intussusception and pull-through (IPT)...
