One of the most common complications of pancreaticoduodenectomy (PD) is delayed gastric emptying (DGE), otherwise known as "gastroparesis," which is not fatal but results in prolonged hospital stay and increased hospital costs. Delayed gastric emptying is defined as nasogastric decompression after postoperative day (POD) 10 or a failure to tolerate a regular diet after POD 14. The incidence of DGE has been reported to range from 5% to 72%.

Further study details as provided by Kochi University:

Primary Outcome Measures:
  • the incidence of DGE [ Time Frame: 3-6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • the incidence of other complication associated with reconstruction [ Time Frame: 3-6 months ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 40
Study Start Date: April 2003
Estimated Study Completion Date: April 2010
Estimated Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: R-Y reconstruction
the reconstruction was performed by R-Y anastomosis
Procedure: R-Y reconstruction
The reconstruction was performed by R-Y anastomosis.
Other Name: the cutting R-Y anastmosis
No Intervention: conventional reconstruction
the anastomosis was performed by B-II

Detailed Description:

We hypothesized that the hand-sewn, two-layered, or continuous suture, could induce anastomotic edema to indeed the afferent peristalsis, which is one of the causes of DGE.
