Pancreas is digestive & endocrine organ of our body. As digestive organ it secrete enzymes which help in digestion mostly fat. It also secrete hormones such as insulin and glucagon which regulate sugar control
Acute Pancreatitis: Common Pancreatic Disease
Pancreas is digestive as well as endocrine organ; helps in fat digestion and blood sugar maintenance, Inflammation of pancreas is acute pancreatitis, most common pancreatic disorder .There are two main reasons one is Alcohol intake and other is Gallstone, Diagnosis is based on increased serum amylase and lipase level and the typical pain abdomen localized to epigastric region and radiating to back; CECT abdomen is done after 72 hrs of onset of pain abdomen to assess the severity of acute pancreatitis.
The course of disease is counted from the day of onset of pain abdomen, Organ failure in the first 72 hr carry a bad prognosis and high mortality rate; Initial phase is body inflammatory response to pancreatitis and can last up to 2-3 weeks, during this phase chances of pancreatic infection is less; After 4th week patient can develop pancreatic abscess and later on acute fluid collection may organize to pseudocyst.
First 2-3 weeks patients require critical care; Respiratory and Inotropic supports if required, Enteral nutrition should be started as early as possible; Most common indication of surgery in these patients is a Pancreatic abscess.
After an episode of acute pancreatitis if peri-pancreatic fluid collection does not resolve then after four weeks these are termed as pseudocysts, Not all pseudocyst require intervention because many of these pseudocysts remain stable or regress; however cyst which are increasing in size and causing pressure symptoms or develop complication require intervention, As many of this Pancreatic Pseudocyst communicate with pancreatic duct simple external drainage is not effective, these require some type of internal drainage into bowel; these drainages can be done either by endoscopy or surgical intervention; MRI abdomen will tell whether the contents of the cyst are liquidified or solid, because if the contents are solid endoscopy drainage will not be success; Surgical intervention are cysto-gastrostomy or cysto-jejunostomy depending on location and size of cyst.
Because pancreas is retro-peritoneal organ, pancreas injury is rare in trauma; Generally pancreas trauma is managed conservatively, pancreas injury is divided into proximal when it involves head and distal when it involves body and tail, when there is complete transaction of the pancreatic duct distal pancreatectomy is done, Pancreatic injury patients may develop pancreatic fistula later on.
Pancreatic head cancer
Risk factors for pancreatic cancer include smoking, alcohol, chronic pancreatitis; Pancreas is divided into three parts head, neck and body region, Symptoms depend at the site of tumor location, if the cancer is located in the head region patient present with jaundice/vomiting and if in neck and body region pain and abdomen mass as the main symptom; weight loss and decreased appetite are common symptom; CECT abdomen is done which show any local and distant spread; If the tumor is resectable the standard surgical procedure is Whipple procedure (Pancreatico-duodenectomy) if the tumor is located in the head region; and if the tumor is located in body and tail region the standard surgical procedure is distal pancreatectomy with splenectomy
Common Pancreatic procedures include Whipple Surgery, Necrosectomy, Pseudocyst drainage & Freys procedure (Lateral pancreatico-jejunostomy). Pancreatic surgery are complex surgeries requiring experienced GI Surgery team and dedicated ICU care for these patients
