Pancreaticoduodenectomy With Arterial Approach of Total Mesenteric Resection of the Pancreas for Pancreatic Head Cancer
Bibliographic record
Abstract
BACKGROUND: This study aims to observe and analyze the clinical efficacy of the pancreaticoduodenectomy (PD) with total mesopancreas excision (TMpE) via the artery approach for carcinoma of head of the pancreas. METHODS: From October 2015 to October 2016, 60 patients with pancreatic head cancer were enrolled in this study. Twenty-eight patients were treated with PD with TMpE via the artery approach (group A), while 32 patients were treated with PD alone (group B) in our hospital. The clinical data of the patients were retrospectively collected, including intra-operative evaluation index, R0 resection rate of postoperative pathological specimens, postoperative complications, and the tumor recurrence time was observed after operation (at third, sixth, and 12th months). Clinical efficacy of PD with TMpE via the artery approach was evaluated between the two groups. RESULTS: There was no significant difference in the operation time or perioperative death between the two groups (P > 0.05). Postoperative specimen pathology showed that there was a statistically significant difference in the R0 resection rate between the two groups (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Tumor recurrence rate at month 3 post operation was 0 (0/28) in group A and 3.13% (1/32) in group B. There was no significant difference in the 6-month recurrence rate (P > 0.05). Postoperative recurrence rate in group A was significantly lower than that in group B at month 12 (P < 0.05). CONCLUSIONS: The PD with TMpE via the artery approach treatment of pancreatic head cancer can reduce the amount of intra-operative bleeding and save the operation time without increasing postoperative complications. It provides effective technical support for combined vascular anastomosis in the treatment of pancreatic head cancer with venous system invasion, and ensures the safety of operation. Moreover, this procedure can improve the R0 resection rate and reduce the recurrence rate in the near future. As a safe, effective and feasible surgical method for the treatment of pancreatic head cancer, it can be widely used in clinical practice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
