Three-Dimensional Vascular Reconstruction of the Pancreas on Multi detector Computed Tomography images and its impact on patients undergoing Pancreatoduodenectomy - A Prospective Observational Study IPDA is difficult to identify in pre op in routine CECT images IPDA is difficult to identify in intra op Identification of those major blood vessels (SMA, MCA, Left Renal vein) that lie around the IPDA and then to measure the distances between these major vessels and the IPDA, helps to determine the location of the IPDA

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pancreaticoduodenectomy (PD) is a complex surgical procedure performed for benign and malignant indications .

Vascular anatomy of the pancreatic head, is important in multiple aspects

* Classical arterial anatomy is observed in 55-79% of cases
* Arterial Variation is observed in around 25-30% of cases
* Relationship of the tumor to the blood vessels determines the resectability of tumor The presence of anatomical variations may increase the risk of complications through
* direct (bleeding due to intraoperative vessel injury)
* indirect (postoperative ischemia of tissues and anastomotic leakage) Preoperative understanding of the vascular anatomy of the pancreatic head is important in order to reduce intraoperative bleeding.
* IPDA is difficult to identify in pre op in routine CECT images. It is identified in only 20% of patients.
* IPDA is difficult to identify in intra op because- It generally originates from the posterior wall of superior mesenteric artery (SMA).The origin of IPDA frequently varies, which makes it difficult to identify in some patients. It is surrounded by dense lymphovascular tissue, which makes it difficult to identify IPDA during surgery.

IPDA can be identified in up to 86% of the time using 3D MDCT . Identification of those major blood vessels (SMA, MCA, Left Renal vein) that lie around the IPDA and then to measure the distances between these major vessels and the IPDA, helps to determine the location of the IPDA.

In the existing studies, they have not defined the impact of identifying IPDA on intra operative parameters ( Operative time, Blood loss) These studies have not used uniform landmarks in the identification of IPDA

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Consecutive adult patients undergoing pancreaticoduodenectomy

All the consecutive patients who undergo pancreaticoduodenectomy will be recruited into the study after obtaining informed consent

Pancreaticoduodenectomy

Intervention Type PROCEDURE

In Pre Operative phase

64 Slice MD CT scan will be taken in all patients undergoing PD in pre op period 3D reconstruction of Peripancreatic vascular system using MDCT images Measure longitudinal distance between Root of Left renal vein, origin of IPDA Measure distance between origin of SMA , MCA and the IPDA

In Intraoperative period

Distance will be measured using standard disposable ruler from Root of Left renal vein to IPDA after Transection of Pancreas followed by specimen removal and to measure the distance between MCA, SMA and IPDA using standard disposable ruler .
