Robotic D3 Partial Duodenal Resection with Primary Side-to-Side Anastomosis
0 Views •
2023
This protocol presents a case of a robotic partial duodenal resection with primary side-to-side duodeno-jejunal reconstruction in a patient with a 5 cm duodenal stenosis. This is done at the third duodenal segment (D3) after an endoscopic mucosal resection (EMR) for a duodenal polyp.

2026
This video case report demonstrates the unique management of a duodenal gastrointestinal stromal tumor with a rare, understudied, exon 8 KIT mutation. Neoadjuvant therapy resulted in a 30% reduction in tumor size, making the patient a candidate for a robotic-assisted duodenal sleeve resection instead of the more morbid pancreaticoduodenectomy.

Laparoscopic surgery is widely used in the treatment of right-sided colon cancer and offers numerous advantages. This paper describes the caudal-to-cranial surgical approach combined with complete mesocolic excision (CME) and D3 lymph node dissection, which may potentially reduce the technical difficulty and appear to be a safe approach.

Source: Alomari, S., et al. Implementation of Minimally Invasive Brain Tumor Resection in Rodents for High Viability Tissue Collection. J. Vis. Exp. (2022)This video demonstrates the use of a minimally invasive resection system (MIRS) to excise tumor tissue from an anesthetized mouse implanted with a tumor. The procedure involves securing the mouse onto a stereotactic frame, reopening the previous surgical site to access the brain, and inserting a specialized cannula that utilizes suction and a...
FAQs
The third portion lies in an anatomically complex region, so surgeons must identify the affected segment while protecting nearby structures and maintaining adequate blood supply. This relationship influences exposure, dissection, vascular control, and the choice of reconstruction. Careful anatomic planning helps limit unnecessary removal and supports preservation of the remaining digestive tract.
Blood-vessel control allows the surgeon to separate and remove the diseased or injured segment while managing the vessels adjacent to the duodenum. It is an essential part of safely isolating the operative field and maintaining viable tissue for reconstruction. The operative findings determine how vascular control is performed and how much intestine can be preserved.
After the segment has been divided and removed, the remaining gastrointestinal tract must be reconnected. A duodenojejunal anastomosis, meaning a surgical connection between the duodenum and jejunum, may be used, although another bowel anastomosis can be selected according to operative findings. The reconstruction aims to restore passage while preserving digestive function.
Removing only the affected portion can provide local treatment while retaining healthy intestine and supporting normal digestive function. This balance is important because the operation must address disease or injury without unnecessarily sacrificing viable bowel. Intraoperative assessment guides the extent of resection and helps determine the most suitable reconstruction.
The procedure generally proceeds by isolating the affected segment, controlling nearby blood vessels, dividing the duodenum, removing the selected portion, and reconstructing gastrointestinal continuity. The sequence is adjusted to the anatomy and operative findings. This structured approach supports local treatment while allowing the surgeon to preserve suitable bowel and plan the final anastomosis.
D3 duodenal resection may be considered for selected disease or injury involving the horizontal portion of the duodenum. Its use depends on the location and extent of the problem, the condition of surrounding structures, and findings during surgery. These factors also guide the amount removed, the reconstruction performed, and subsequent patient assessment.
Postoperative care must account for the resected segment, the reconstructed bowel connection, and the condition of the surrounding tissues. Patient assessment focuses on recovery after restoration of gastrointestinal continuity and on recognizing potential complications associated with the operation. Understanding the surgical anatomy and sequence helps clinicians interpret the postoperative course and plan appropriate follow-up.
