Our results are comparable to previous studies (19-22) and indicate that EMR remains an acceptable method for treating <20 mm colorectal LSTs with regard to mean procedure time, en bloc resection
rate, and complete resection rate.
The patient underwent en bloc resection
of the mass by a head and neck surgeon, with preservation of the spinal accessory nerve.
When a tumour spilled into a joint, an en bloc resection
would be preferable.
In our series, we performed en bloc resection
in all patients and adhesions were confirmed as malignant in all patients after histopathologic examination.
Endoscopic submucosal dissection (ESD) has been gaining wide-spread acceptance as a treatment for gastric neoplasms, including early gastric cancer, GIST (gastrointestinal stromal tumor), and so on , because of its high rate of en bloc resection
.1-3 The "grasp-and-snare" technique in EMR, using snare and injection needle devices, has been proven to be safe and effective.4,5 Nonetheless, "grasp-and- cut" ESD can become a technically demanding and particularly time-consuming procedure in cases with large(2-4 cm) or giant (>4 cm) lesions, and there are still several unsolved problems associated with ESD using, such as high incidence of perforation, bleeding, and other complications.3
Ifpenis, prepuce, and regional lymph nodes are extensively involved, surgical options are en bloc resection
with or without penile retroversion [13-15] or penile transection just distal to a perineal urethrostomy [16,17].
NNA - En bloc resection
of tumors of the bladder using HybridKnife is a new surgical procedure that allows recently discovered cancer of the bladder to be effectively treated.
Table 4: Frequency of en bloc resection
of adjacent organs in gastric carcinoma cases.
The tumor is reported to be treated with a segmental or en bloc resection
of the mandible.
Patients with resectable lesions who are candidates for operation should be treated by en bloc resection
with clear margins, since this provides the best chance for a cure.
Concerning the clinicopathological characteristics of the duodenal neoplasms, following data were collected: en bloc resection
rate, R0 resection rate, resected specimen size, resected lesion size, operation time, estimated blood loss, number of port sites, rate of conversion to open surgery, complication (anastomotic leakage, stenosis and bleeding), time until restart of oral intake, and postoperative hospital stay length.
Therefore en bloc resection
and subsequent reconstruction with an osteoarticular allograft was performed.
