After PPPD, we have consistently performed gastrointestinal reconstruction by
Imanaga procedure that entailed an end-to-end dudenojejunostomy, end-toside
pancreatojejunostomy (pancreatic duct to jejunal mucosa anastomosis) and
choledochojejunostomy, performed in that order.
PPPD-Imanaga, which leaves no blind intestinal segment, simulates the normal
anatomic arrangement and provides a physiological mixture of food and bile
in the upper portion of the jejunum. The good mixing was evidenced by dual
scintigraphy with few exceptions. As another advantages, insertion of endoscopy
is easier postoperatively and as a result, we can check patency of pancreatic and
biliary anastomotic stomas. This is important to evaluate postoperative function
of remnant pancreas and liver, and early to detect local recurrence.
Since 1986, we have experienced 272 cases of PPPD/PD-Imanaga (PPPD 233
/ PD 39), which consists of patients with pancreatic head cancer 122, bile duct
cancer 55, Vater cancer 36 and another 61.
Overall 5-year-survival is 14.2% in pancreatic head cancer, and 25.3% in distal
bile duct cancer.

For the treatment of pancreatic cancer, it is most important to perform radical
resection (R0) and in addition, an adequate and effective adjuvant therapy will be
required. We have performed radical operation including combined resection of
the vessels, if necessary. On the other hand, to maintain the patient’s quality of
life and to adopt sufficient adjuvant therapy, we have also made effort to preserve
organ function as much as possible.
In cases of pancreatic body and/or tail cancer, cancer often invades to the origin
of the common hepatic artery, the splenic artery or the celiac axis (CA). For
such cases, we performed “whole stomach-preserving distal pancreatectomy with
combined resection of the celiac axis (WSP-DP-CAR)” in 1987, and published as
the first report in 19911).
In this procedure, the arterial blood supply to the whole stomach and the liver is
secured only via the inferior pancreaticoduodenal artery arising from the superior
mesenteric artery (SMA). So the bifurcation of the gastroduodenal artery (GDA)
from the common hepatic artery must be safely preserved after strict evaluation
whether cancer invades to this site or not.
The indications of this procedure should be applied to patients who diagnosed as
1) no distant metastases, 2) no tumor involvement of the SMA and GDA and 3)
resectable extrapancreatic nerve plexus invasion or lymph node metastases, and
will undergo pancreatectomy with curative intent.
Since June 1987, we have performed this procedure to sixteen cases. For two
cases, we were able to preserve the left gastric artery, and for five cases, the
portal vein was resected and reconstructed. There were no severe postoperative
complications, though delayed gastric emptying (DGE) in two cases, pancreatic
fistula (Grade B: ISGPF) in three cases were observed, and there was no problem
with the blood supply to the stomach and the liver. For ten cases, we obtained
complete resection (R0). Due to the good postoperative state, adjuvant therapy
could be applied to all cases intended. Up to the end of July 2014, five patients
still survive (four have no recurrences), eight patients lived more than one
year (one year survival rate: 69.6%), two patients lived more than five years,
including one 205-months-survivor. Median survival time (MST) of all patients
is 18.8 months. There was no local recurrence except for only one non-curative
resection case due to the tumor invasion to the pancreatic cut margin.
This procedure of WSP-DP-CAR has been safely performed and the postoperative
course is almost same as that of standard distal pancreatectomy. We will perform
this procedure because there is a chance that it may enhance local control and
improve survival of pancreatic cancer invading around the CA.
I will present this procedure of WSP-DP-CAR, using the motion picture.
