Pancreatitis in pediatric patients with pancreatic solid pseudopapillary neoplasms- a single center experience

What This Episode Covers

A single-center case series examining an unexpected complication: adolescent patients who develop chronic pancreatitis after curative resection of solid pseudopapillary neoplasms 0:09 0:15 0:22 0:25. The focus is on genetic and anatomic risk factors that predict this outcome 0:32 0:48.

Key Findings

Solid pseudopapillary neoplasms are one of the most frequent pancreatic tumors in pediatric patients 0:09. Surgery is usually curative and outcomes are excellent 0:15. In this series, 10 adolescent girls underwent surgical resection 0:22.

Three of the 10 patients developed acute recurrent or chronic pancreatitis after resection 0:25. Every patient who developed ongoing pancreatitis had genetic risk factors like CFTR gene variants or pancreas divisum 0:32. Some patients with post-resection pancreatitis ultimately required completion pancreatectomy 0:40.

Clinical Implications

The pattern is clear: resection of a low-grade tumor in a patient with underlying pancreatic vulnerability can unmask or precipitate chronic pancreatitis 0:25 0:32. The genetic and anatomic factors identified here — CFTR variants and pancreas divisum — are known pancreatitis risk factors in other contexts 0:32. Their presence in every patient who developed post-resection pancreatitis suggests they are not incidental 0:32.

Identifying genetic and anatomic risk factors before surgery may change management of patients with solid pseudopapillary neoplasms 0:48. For a trainee, this means considering preoperative genetic testing and detailed pancreatic duct imaging in patients with these tumors 0:48. The decision to resect remains straightforward when risk factors are absent, but when present, the discussion with the family must include the possibility of trading a curable tumor for chronic pancreatitis — and potentially completion pancreatectomy 0:25 0:40.

The series does not resolve what alternative management might look like for high-risk patients, nor does it quantify the risk precisely 0:48. It establishes that the risk exists and is not rare in this small cohort 0:22 0:25.

What This Episode Covers

A single-center case series examined outcomes after surgical resection of solid pseudopapillary neoplasms in ten adolescent girls and found an unexpectedly high rate of post-resection pancreatitis linked to underlying genetic and anatomic risk factors 0:22 0:25. The findings suggest that preoperative risk stratification may alter surgical planning for what is typically considered a straightforward resection.

Key Findings

Solid pseudopapillary neoplasms are one of the most frequent pancreatic tumors in pediatric patients, and surgery is usually curative with excellent outcomes 0:09 0:15. In this series, however, three of ten patients developed acute recurrent or chronic pancreatitis after resection 0:25. Every patient who developed ongoing pancreatitis had identifiable risk factors: CFTR gene variants or pancreas divisum 0:32. Some of these patients ultimately required completion pancreatectomy 0:40.

Clinical Implications

The association between genetic variants and anatomic anomalies with post-resection pancreatitis raises the question of whether preoperative genetic testing and detailed pancreatic imaging should be routine. Identifying CFTR variants or pancreas divisum before surgery may change management — whether that means more conservative resection margins, prophylactic ductal interventions, or in some cases reconsidering the timing or extent of resection 0:48. The series is small, but the pattern is consistent: all three cases of post-resection pancreatitis occurred in patients with identifiable predisposing factors.

What This Changes

For surgeons and gastroenterologists managing pediatric pancreatic masses, this series argues against treating all solid pseudopapillary neoplasms as uniformly low-risk. The tumor itself may be indolent, but the operation and its sequelae are not risk-free when the patient carries genetic or anatomic vulnerabilities. Preoperative workup should include CFTR sequencing and careful assessment for pancreas divisum. For patients with these risk factors, shared decision-making should include the possibility of recurrent pancreatitis and the potential need for further intervention, including completion pancreatectomy.
