Study Details

Study Description

Brief Summary

Postoperative fistula is the major complications of distal pancreatectomies which prohibit patients' recovery. Previous studies have reported controversial results regarding the efficacy of pancreatic stump reinforcement methods. Prior research has commonly included minimally invasive and open cases together. Moreover, stapler and suture were combined in most studies making interpretation difficult. Data has shown that staple line plus reinforcement might potentially decrease the CR-POPF rate of patients who underwent distal pancreatectomies, but well-designed high-quality evidence is lacking. Thus, the investigators design the present study to the question that whether routine staple line plus reinforcement would bring benefit for participants.

Detailed Description

Distal pancreatectomy (DP)is the standard surgical method for benign or malignant pancreatic tumors locating at body and tail [1]. Clinically relevant postoperative pancreatic fistula (CR-POPF) is the major complication after pancreatectomy. In literature, reported CR-POPF rate after distal pancreatectomy varied between 5% and 64% from different centers. It's still a challenge to prevent CR-POPF via effective pancreatic remnant closure and no consensus on the optimal surgical technique has been established. Reported surgical strategies to prevent CR-POPF included stapler transection, staple line reinforcement, stump coverage with autologous tissue or fibrin glue, mesh reinforcement, and prophylactic administration of octreotide. However, none had convincing outcome [2-4].

Data has shown that staple line plus suture reinforcement might potentially decrease the CR-POPF rate of patients who underwent distal pancreatectomies, but well-designed high-quality evidence is lacking. Meanwhile, prior researches have commonly included minimally invasive and open cases together. Moreover, stapler and suture were combined in most studies making interpretation difficult [5-8].

Thus, the investigators design a single-centered, parallel, randomized controlled trial to compare the efficacy of routine staple line plus reinforcement versus staple only on the CR-POPF rate of participants who underwent minimally invasive distal pancreatectomies.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Staple line plus reinforcement

In this experimental group, a lock stitch will be placed after transecting the pancreas with stapler.

Procedure: reinforcement of the staple line
The operator will perform reinforcement of the staple line with a continuous lock stitch.

Other: staple line with no reinforcement

In this control group, no additional reinforcement is used after transecting the pancreas with stapler.

Procedure: staple only
The operator transect the pancreas with stapler only, without staple line reinforcement.

Outcome Measures

Primary Outcome Measures

  1. Clinically relevant postoperative pancreatic fistula (CR-POPF) [Postoperative postoperative day 30.]

    CR-POPF is defined according to the revised 2016 version of ISGPS (International Study Group on Pancreatic Surgery) classification and grading of POPF. A CR-POPF is defined as a drain output of any measurable volume of fluid with amylase level greater than 3 times the upper Institutional normal serum amylase level, associated with a clinically relevant development/condition related directly to the POPF.

Secondary Outcome Measures

  1. Operative time [Postoperative postoperative day 30.]

    Skin-to-skin time

  2. Estimated blood loss [Postoperative postoperative day 30.]

    Total blood loss during surgery

  3. Length of postoperative hospital stay [Postoperative postoperative day 30.]

    Days of hospital stay after surgery
