ABSTRACT
Objective To study the preoperative diagnosis and treatment strategy of laparoscopic pancreatoduodenectomy (LPD) in patients with arterial anomalies.Methods The clinical data of 16 patients with arterial anomalies who underwent counterclockwise LPD at the Hunan People's Hospital from January 2016 to December 2017 were analyzed.Results The operation time was 370.0±109.0 min.The blood loss was 92.0±45.0 ml.In 14 patients,arterial anomalies were found preoperatively and were confirmed intraoperatively.The number of patients with a replaced right hepatic artery (rRHA),common hepatic artery (CHA) which originated from superior mesenteric artery (SMA),right hepatic artery (RHA) crossing in front of common bile duct (CBD),celiac artery (CA) and SMA with a common origin,right renal artery (RRA) anomaly were 5,3,3,2,and 1,respectively.In 2 patients,the anomalies were not found before operation:a dorsal pancreatic artery (DPA) originating from CHA,and a cystic artery and a right gastric artery (RGA) originating from left hepatic artery (LHA).Operative complications included biochemical fistula in 3 patients;peritoneal local effusion in 2 patients;pleural effusion in 2 patients;gastrointestinal anastomosis bleeding in 1 patient;delayed gastric emptying in 1 patient;a proper hepatic artery (PHA) pseudoaneurysm in 1 patient;and a subumbilical incision infection in 1 patient.The pathological results showed all the 16 patients had malignant tumors of the pancreas or ampulla.All the tumors were resected by R0 resection.Conclusion Arterial anomaly was common in LPD.Preoperative targeted radiological reading of X-rays,regional anatomical division combined with counterclockwise resection could result in early detection,identification and help to protect the arterial anomaly from injury and reduce the risk of serious postoperative complications.
