Abstract
Background and Aims
Endoscopic ultrasonography-guided ethanol lavage and Taxol injection (EUS-ELTI) in pancreatic cystic lesions have been recently performed in some medical centers. This study aimed to optimize the patient selection and analyze the outcomes in patients who underwent surgery after EUS-ELTI in pancreatic cystic lesions.
Methods
Among 310 patients who underwent EUS-ELTI between January 2007 and December 2014, 23 underwent surgery after EUS-ELTI owing to incomplete treatment and/or adverse events. We evaluated the surgical outcomes in patients who underwent surgery after EUS-ELTI. Then, we retrospectively compared the clinical outcomes of the patients who underwent the surgery after EUS-ELTI with those of patients who underwent upfront surgery for left-sided pancreatic lesions without the EUS-ELTI procedure.
Results
The pathology revealed degenerated cysts in 12 patients, mucinous cyst neoplasms in five patients, neuroendocrine tumors in two patients, and one intraductal papillary mucinous neoplasm (IPMN), one solid pseudopapillary tumor, one pancreatic ductal adenocarcinoma arising from an IPMN, and one hepatoid carcinoma. Twelve patients underwent laparoscopic distal pancreatectomy and five patients underwent open distal pancreatectomy. All six patients who had lesions in the pancreatic head underwent open pancreaticoduodenectomy. When we retrospectively compared the clinical outcomes between patients who underwent laparoscopic distal pancreatectomy after EUS-ELTI and those who did not receive the EUS-ELTI procedure, the spleen-preserving rate was 0% in the EUS-ELTI group and 61.7% (365/592) in the non-EUS-ELTI group (P < 0.001). Clinically relevant postoperative pancreatic fistulas occurred in 33.3% of patients in the EUS-ELTI group and in 6.8% of patients in the non-EUS-ELTI group (P = 0.025). The mean postoperative hospital stay was also shorter in the non-EUS-ELTI group than in the EUS-ELTI group (8.66 ± 5.66 and 13.56 ± 7.20, P = 0.032).
Conclusion
Surgical outcomes are compromised after EUS-ELTI in the cystic tumor of the pancreas. Further investigations are needed for investigation of the efficacy and safety of the EUS-ELTI procedure.
