Other indications for pancreaticoduodenectomy include chronic pancreatitis, benign tumors of the pancreas, cancer metastatic to the pancreas, multiple endocrine neoplasia type 1 [5] and gastrointestinal stromal ...
The resected size and shape can be controlled, en bloc resection is possible even in a large neoplasm, and neoplasms with submucosal fibrosis are also resectable. So this technique can be applied to the resection of complex neoplasms such as large neoplasms, ulcerative non-lifting neoplasms, and recurrent neoplasms.
Ostectomy or En – bloc resection: in addition to the above treatments, these may be required due to the issue of recurrence. Ostectomy is removal of peripheral bone. En – block resection is removal of the cyst with the surrounding tissue. Extensive cysts may require a bone graft after bone resection and reconstruction of the area.
Cases in which a lung tumor invades the chest wall and an en bloc resection of ribs must be performed to achieve negative resection margins generally are felt to abrogate the value of VATS. Also pneumonectomy by VATS is a safe and feasible treatment for both benign and malignant lung diseases that induces acceptable damage and has lower morbidity.
At an early stage, colorectal cancer may be removed during a colonoscopy using one of several techniques, including endoscopic mucosal resection or endoscopic submucosal dissection. [5] Endoscopic resection is possible if there is a low possibility of lymph node metastasis and the size and location of the tumor make en bloc resection possible ...
Resection may refer to: Resection (surgery), the removal by surgery of all or part of an organ or other body structure; Segmental resection (or segmentectomy), the partial removal of an organ or other body structure; Position resection and intersection, a means of establishing a location by measuring angles only to known points
Using a double-channel scope, the lesion is grasped and lifted by the first snare and strangulated with the second snare for complete resection. [citation needed] Endoscopic resection with injection of concentrated saline and epinephrine is carried out using a double-channel scope. The lesion borders are marked with a coagulator.
