简要总结
Main indications for distal pancreatectomy (DP) are pancreatic body and tail tumors including ductal adenocarcinoma, neuroendocrine tumors, and cystic neoplasms. Despite a less invasive operation with lower morbidity compared to pancreatic head surgery, DP is burdened by the occurrence of clinically-relevant postoperative pancreatic fistula (CR-POPF) in a significant proportion of patients.
Drain fluid amylase (DFA) on POD 1 (postoperative day 1) > 2,000 U/L appears as the best performing threshold to predict the occurrence of CR-POPF after distal pancreatectomy. Although there is preliminary evidence that early drain removal in the subgroup of patients with DFA1 < 2,000 U/L may reduce POPF, no prospective study has yet evaluated the impact of an early drain removal strategy compared to standard management.
The research question of this study is to evaluate to what extent early postoperative drain removal according to a validated DFA1 impact on clinically-relevant POPF rate after distal pancreatectomy in comparison to standard drain management. The primary hypothesis is that, early drain removal will result in a reduced proportion of patients experiencing grade B-C POPF according to ISGPS definition.
The proposed study is a two-group, assessor-blind, randomized trial. Participants will be randomly assigned with a 1:1 ratio into one of two groups: (1) standard drain management or (2) early drain removal strategy.
In this study adults (>18 years) patients with pancreatic body or tail diseases planned for distal pancreatectomy with or without splenectomy will be enrolled.The primary outcome is the POPF at 90 days after surgery, defined as grade B or C POPF according to ISGPS definition.
Participants will be asked to complete some questionnaires in order to assess their general health status, and they will be evaluated at time of hospital admission, at 15 days, at 30 days after surgery (via telephone follow-up), and at 90 days after surgery (via telephone follow-up).
详细描述
RATIONALE AND RESEARCH QUESTION Distal pancreatectomy (DP) is defined as the resection of the left portion of the pancreas extending from the neck to the tail of the gland. DP is burdened by the occurrence of clinically-relevant postoperative pancreatic fistula (CR-POPF) in a significant proportion of patients.Traditionally, during DP drains were placed intraoperatively in proximity of the pancreatic stump to mitigate the potential occurrence of POPF. Postoperatively, drains were usually kept in place until a POPF was ruled out by the presence of drain fluid amylase (DFA) values lower than 3-fold the upper limit of normal serum amylase, and a non "sinister" appearance of drain fluid in accordance with the International Study Group on Pancreatic Surgery (ISGPS) definition. For this reason, drains were usually maintained in place after surgery for at least 5 - 7 days. Although there is some preliminary evidence that early drain removal in the subgroup of patients with DFA1 < 2,000 U/L, no prospective study has yet evaluated the impact of an early drain removal strategy compared to standard management. Therefore, the overall aim of this study is to contribute evidence about the effect of an early drain removal policy on postoperative outcomes following distal pancreatectomy.
The primary research question is to evaluate to what extent does early postoperative drain removal according to a validated DFA1 impact on clinically-relevant POPF rate after distal pancreatectomy in comparison to standard drain management. The primary (confirmatory) hypothesis is that, early drain removal will result in a reduced proportion of patients experiencing grade B-C POPF according to ISGPS definition.
Furthermore the exploratory hypotheses that, in comparison to standard care, early drain removal will: (1) reduce time to postoperative functional recovery, (2) reduce number and severity of postoperative complications, (3) reduce postoperative surgical site infections, (4) improve self-reported physical function status, (5) improve generic health-related quality of life and (6) be cost-effective, will be tested.
STUDY DESIGN AND PARTICIPANTS The study is designed as a two-group, assessor-blind, randomized trial. Participants will be randomly assigned with a 1:1 ratio into one of two groups: (1) standard drain management or (2) early drain removal strategy. The intervention will be provided during hospital stay. Adult people with pancreatic body or tail diseases (i.e. pancreatic cancer, cystic neoplasms, pancreatic neuroendocrine tumors, etc.) planned for distal pancreatectomy with or without splenectomy at the San Raffaele Hospital IRCCS (HSR) will be considered for inclusion.
