Abstract
Pancreatic pseudocyst is a collection of pancreatic juice outside the normal ductal network of the ductal system that lacks epithelial lining and can be located almost everywhere in the abdominal cavity. In most of the time however they are found in the lesser sac behind the stomach (Alaa et al., 2004).
A pseudocyst results from disruption of the pancreatic ductal system, occurring most commonly in acute pancreatitis and less commonly in chronic pancreatitis, trauma, or with pancreatic neoplasms (John et al., 2001).
The natural history of pancreatic pseudocysts, which allows to rationally plan their management, has paralleled improvements in abdominal imaging. In an early study using serial transabdominal US, reported that pseudocysts persisting for longer than six weeks were unlikely to regress and were frequently associated with complications. It is now known that many pancreatic pseudocysts resolve spontaneously. Operative management was performed only for such complications as persistent abdominal pain, pseudocyst enlargement, and infection (Yeo et al., 1999).
In 2002, Nealon and Walser proposed a classification based solely on pancreatic duct (PD) anatomy :
Type I: Normal duct, no communication.
Type II: Normal duct with duct-cyst communication.
Type III: Otherwise normal duct with stricture no duct-cyst communication.
Type IV: Otherwise normal duct with stricture and duct-cyst communication.
Type V: Otherwise normal duct with complete cut-off.
Type VI: Chronic pancreatitis, no duct-cyst communication.
Type VII: Chronic pancreatitis with duct-cyst communication.
There are four approaches of pseudocyst drainage once the need is recognized. Open surgical drainage by way of cyst-gastrostomy, jejunostomy or duodenostomy (Sarr et al., 2000). Laparascopic drainage either cyst-gastrostomy or jejunostomy in contrast to other technique allows a confident biopsy of the pseudocyst wall (Murr et al., 2003). Endoscopic drainage is the treatment of choice in some centers either trans-mural or trans-papillary (Sarr et al., 2000), and Percutaneous drainage it was originally performed for infected cyst and sever embarrassment with immature cyst. The improvement of US, CT, and MRI can greatly facilitate accurate localization of the pseudocyts (Alaa et al., 2004).
Aim of the work :
Is to identify the various modalities of management of pancreatic pseudocysts.
