Subcutaneous Destruction of Sinus Tract with Long-term Vessel Loop Drainage as a Minimally Invasive Surgical Treatment for Primary Pilonidal Sinus.

The surgical management of pilonidal disease ranges from minimally invasive techniques to wide excision with secondary wound healing. Hypothetical counterarguments for using the minimally invasive techniques are that these techniques only incompletely remove the sinus tract and that they allow the formation of subcutaneous cavities as a result of rapid closure of small skin incisions. In order to avoid these problems we used a vessel loop drainage after subcutaneous destruction of the sinus tract.

Individual surgery for gastric gastrointestinal stromal tumors.

The management of gastric gastrointestinal stromal tumors (GIST) is complex. Local tumor resection with disease-free resection margins without lymphadenectomy is the treatment of choice for primary non-metastatic tumors. This can be achieved with several techniques including wedge resection, transgastric resection, partial gastrectomy, total gastrectomy, and multivisceral resection.
