The most useful issue is differentiation between early and advanced GC, which allows for potential endoscopic resection versus more invasive surgical resection and/or neoadjuvant chemotherapy, respectively.
Second, the tumors in the incomplete resection group may have been more invasive, which made a complete resection rather difficult during the surgery.
As such it can be offered to patients who could not withstand more invasive procedures such as surgical resection.
Although the recurrence rate after TEM is higher than after radical resection for more invasive tumours, TEM offers an alternative in patients with significant co-morbidity [ 27].
Basically, palliative reduction is thought to be appropriate for pressure symptoms of simple liver cysts [1], but marsupialization or percutaneous drainage may be insufficient, and more invasive procedures such as cystic wall resection and hepatectomy may be recommended to prevent the recurrence of the symptoms.
Continued experience in evaluating quantitative measures in combination with morphologic features, including margin contour, internal architecture, and nodule size, will further aid in guiding crucial decisions pertaining to the use of CT surveillance vs more invasive approaches including biopsy and surgical resection.
The more invasive biliopancreatic diversion with duodenal switch (BPD-DS) results in a partial resection of the stomach with the pylorus retained, bypass of jejunum and proximal ileum, and an approximately 250 cm delay of the bile inlet.
However, such a trial comparing laparoscopic with open hepatic resection is likely to be challenging, as patients may resist being randomized to a more invasive procedure.
How much more invasive can one get?
But some looks are more invasive than others.
