Study Notes
Pancreatic Injury and Complications
- Pancreatic injury incidence during splenectomy is up to 6%, with a retrospective study indicating 16% during laparoscopic procedures.
- Isolated hyperamylasemia occurs in half of the pancreatic injury cases during laparoscopic splenectomy.
- If pancreatic injury is suspected, place a closed suction drain adjacent to the pancreas and obtain drain amylase prior to patient discharge.
- Colonic injuries are rare but possible during mobilization due to proximity; mechanical bowel preparation isn't recommended.
- Gastric injuries can arise from direct trauma or thermal damage during short gastric vessel division; oversewing concerning areas is advised.
- Diaphragmatic injuries may occur with splenic pole mobilization, especially in perisplenitis; careful dissection of the splenophrenic ligament can reduce risk.
Early Postoperative Complications
- Pulmonary complications affect nearly 10% of open splenectomy patients, significantly less common in laparoscopic cases.
- Subphrenic abscess occurs in 2-3% after open splenectomy but is uncommon (0.7%) in laparoscopic cases; treatment involves percutaneous drainage and IV antibiotics.
- A prolonged postoperative ileus after open splenectomy warrants evaluation for possible complications like subphrenic abscess or portal vein thrombosis (PVT).
- Wound complications such as hematomas and infections are more frequent (4-5%) after open splenectomy compared to minimally invasive techniques (1-2%).
- Thrombocytosis and thrombotic complications can arise post-splenectomy; symptoms of PVT occur in 8-12.5% of patients and can lead to mesenteric thrombosis if untreated.
Late Postoperative Complications
- Overwhelming postsplenectomy infection (OPSI) can occur throughout an asplenic patient's lifetime, with a mortality rate of 0.73 per 1,000 patient years.
- Cancers of the distal pancreas have a high potential for peritoneal metastases without surgical palliation; elevated CA19-9 levels might indicate metastatic disease.
Surgical Treatment Options
- The Whipple procedure (pancreaticoduodenectomy) involves the resection of the pancreatic head, distal bile duct, duodenum, jejunum, and gastric antrum.
- Pylorus-sparing Whipple has not shown improved survival or lower morbidity compared to traditional methods.
- Distal pancreatectomy is preferred for lesions in the body and tail of the pancreas, typically involving spleen resection.
- The radical antegrade modular pancreatosplenectomy (RAMPS) technique improves R0 resection rates for distal pancreatic tumors over traditional approaches.
- Minimally invasive pancreatectomy demonstrates similar outcomes in overall survival and R0 resection rates compared to open surgeries.
Common Postoperative Considerations
- Delayed gastric emptying, pancreatic fistula, and wound infection are common complications following pancreaticoduodenectomy.
