'noli me tangere' - Latin phrase for 'Touch Me Not'
According to the Wikipedia, the organ that typically fits the description of this phrase is the pancreas. This is due to some of the perceived attributes of pancreas and its surgery - the location of pancreas with resultant difficulty in accessing it during 'routine' abdominal operations, its close relation to major blood vessels and significant morbidity of pancreatic operations.
No wonder the maxim "eat when you can, sleep when you can, don't mess with the pancreas" was a common surgical anecdote. In the current times, such wisecracks are merely of historical interest and no longer hold any validity.
Emergence of specialized pancreatic surgeons with better understanding of pancreatic diseases & refined surgical techniques coupled with an effective management of procedure related complications has resulted in the current era of pancreatic surgery with low mortality and acceptable morbidity.
Modern pancreatic surgery can aptly be described as being safe, elegant, patient friendly surgery that is based on highest quality medical research ('medical evidence') and increasing utilizes minimally invasive surgery techniques such as robotic surgery.
Over last 2 decades, notable advancements have been made in all domains of pancreatic surgery for:
- Pancreratic necrosis following severe acute pancreatitis
- Chronic pancreatitis
- Pancreatic cancer
These are briefly discussed in following sections.
Surgery for infected pancreratic necrosis following severe acute pancreatitis (SAP)
SAP with bacterial infection of pancreatic necrosis is one of most serious pancreatic diseases that necessitates intervention for salvage. About a decade ago, this disease entity was treated by open surgical removal of dead peripancreratic tissue ('necrosectomy') – a procedure associated with high mortality and complication rates.
Over the last decade, 'Step Up Approach' has emerged as the preferred alternative treatment strategy for SAP patients with infected necrosis. As an initial management, surgical drains are placed in such infected collections under CT scan guidance. This minimally invasive approach may help avoid further surgical intervention in up to 2/3 of SAP patients with infected necrosis. The patients who do not adequately respond to such drain placement are advised to undergo a laparoscopic necrosectomy.Modern management of infected pancreatic necrosis has thus evolved towards more patient friendly minimally invasive interventions with better outcomes.
Surgery for chronic pancreatitis (CP)
The aim of treatment for patients with CP is lasting relief of pain and available options include endoscopic therapy and surgery. It is pertinent to add that pancreatic ductal stones in the absence of pain do not require any further treatment. High impact studies over last 10 years show that following endotherapy, pain is likely to recur in up to 2/3 of patients within 2 years. In contrast, surgery for CP has several advantages. It can be performed safely with minimal blood loss and postoperative complications and offers a lasting pain relief in up to 80% patients. Also there is emerging evidence that an early surgery may lead to preservation of pancreatic function.
Minimally invasive surgical techniques are being increasing utilized which make surgery for CP more acceptable option than ever before.
Whipple's procedure for resectable cancer of head of the pancreas
Whipple's procedure is the only currently available treatment that can potentially provide long term survival for pancreatic head cancer. Emergence of specialized pancreatic surgeons, refinements in surgical techniques and image guided, effective management of complications have resulted in mortality of Whipple's procedure ranging between 1-5% at centers of excellence
With safety of the Whipple's procedure no longer a matter of debate, novel strategies are now being adapted to expand the indications of surgery. These include the concept of 'Borderline Resectable Pancreas Cancer' and initiation of neoadjuvant therapy to downstage the disease in order to make it amenable for margin negative resection.
Also in line with other domains of pancreatic surgery, minimally invasive surgery techniques including robotic assisted surgery are being increasing utilized for Whipple's procedure without any compromise on quality or safety of surgery.
Department of Surgical Gastroenterology, Max Superspeciality Hospital, Saket, New Delhi, has successfully incorporated all aforementioned best practices and surgical advancements including minimally invasive robot assisted surgery to provide state of art management of pancreatic diseases at outcomes that are comparable to international centers of excellence.
