No-Touch isolation procedures might prevent the dissemination of cancer cells from the primary tumor. However, these techniques are not widely accepted in laparoscopic pancreatoduodenectomy (LPD) by now. We herein present in-situ No-Touch isolation LPD with partial resection and reconstruction of the superior mesenteric vein (SMV) for pancreatic cancer after neoadjuvant therapy.
Laparoscopic pancreatoduodenectomy (LPD) is a standard radical operation for pancreatic head malignant tumors by now. Due to the complex laparoscopic resection and reconstruction techniques, it is difficult to perform LPD for patients with locally advanced pancreatic head cancer after neoadjuvant therapy. Our team initiates LPD using the in-situ No-Touch isolation technique. The innovation and optimization of this modified No-Touch isolation technique emphasize exploring the distal section of superior mesenteric vein (SMV) and the left side of the superior mesenteric artery (SMA) prior to evaluating the resectability by subcolonic mesenteric approach, which is an ideal exploring approach. After that, we use the median-anterior, and left-posterior of SMA approaches to cut off the blood flow of the pancreatic head to make the tumor isolated intact, then move and dissect the tumor. It is a process fitting the surgical principle of tumor-free. This article aims to demonstrate the feasibility and safety of performing LPD using the in-situ No-Touch isolation technique, which might elevate the R0 resection rate. It is an oncological ideal operation process.
Pancreaticoduodenectomy (PD) is a standard surgical procedure for cancer in the pancreaticoduodenal region. The Kocher maneuver is widely used for the efficient exposure of the duodenum and pancreatic head during conventional PD. The mobilization and squeezing of the pancreaticoduodenal area during surgery may cause metastasis of the tumor cells before the ligation of surrounding vessels1. A recent study had shown that the tumor cells had the potential possibility of being squeezed into the portal vein (PV) because of the handling and squeezing of the tumor area by the surgeons, which might further increase the risk of liver metastasis after surgery2.
With the development of biomedical technology, a scientist could detect the spread of solid tumor cells, including pancreatic cancer cells, into the vessels as circulating tumor cells (CTC)3,4.
No-Touch isolation procedures, which have been used in colon cancer, might prevent the dissemination of cancer cells, such as circulating tumor cells, from the primary tumor5. Several studies have reported the use of a no-touch isolation technique for pancreatic head cancer during laparotomy pancreaticoduodenectomy6,7. The concept of this procedure is that the surgeon does not touch the duodenum and pancreatic head region (including the tumor) before ligating and dissecting the vessels (arteries and veins) around the pancreatic head.
No-Touch isolation techniques have been reported in LPD for pancreaticoduodenal region neoplasm8. We herein present a modified in-situ No-Touch isolation LPD with partial resection and reconstruction of SMV for pancreatic cancer after neoadjuvant therapy, which dissects all the inflow arteries first, transects the involved vein with sufficient margin, resects the tumor in-situ, and removes the specimen en-bloc.
The goal and advantages of this method are to ensure that all steps follow the oncologic principles of No-Touch in order to decrease the risk of metastasis of the tumor cells. The rationale behind the development and use of this technique is that the tumor should be mobilized at the final stage, including resecting the tumor in situ and removing the specimen en bloc after tumor inflow arteries and outflow veins are occluded. However, as this procedure requires complex resection and reconstruction techniques when surgeons decide whether to use this method, they need to estimate their own situations such as the learning curve, tumor type, vascular condition, and other factors.
This study was permitted by the Ethics Committee of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine.

A 55-year-old man with upper abdominal pain and marasmus was diagnosed with a 4.2 cm x 3.1 cm tumor in the uncinate process of the pancreas, and the SMV was involved over 180° (Figure 5). The patient was previously healthy and had a relatively normal body mass index (19.47 kg/m2). No distant metastasis was found on the preoperative contrast-enhanced CT scan. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed to acquire the pathology diagnosis of adeno...
PDAC is one of the most lethal malignant diseases. Despite the fact that the overall 5-year survival rates are still unsatisfactory, surgery remains the only curative therapeutic method till now10. According to the National Comprehensive Cancer Network (NCCN) and International Study Group of Pancreatic Cancer (ISGPS), patients diagnosed with PDAC should be defined as borderline resectable cases while the portal-superior mesenteric vein is suspiciously involved, and in order to improve R0 resection...
