Laparoscopic hepaticojejunostomy and gastrojejunostomy for palliative treatment of pancreatic head cancer in 48 patients.

INTRODUCTION: Approximately 80% of patients with pancreatic cancer are not candidates for curative resection at the time of diagnosis. The objective of this study is to show that although endoscopic treatment is the standard palliation, surgical laparoscopic treatment is both feasible and effective for these patients. MATERIALS AND METHODS: Preoperative resectability was evaluated by dynamic contrast-enhanced computed tomography scans. Endoscopic palliation was the first choice for patients with metastatic disease and for patients with locally advanced pancreatic cancer with bad performance status. Laparoscopic surgical palliation was indicated for patients with jaundice and locally advanced pancreatic cancer (elective palliation) and for patients with jaundice with metastatic disease and failure in the endoscopic/percutaneous treatment (necessary palliation). Elective palliation consisted of Roux-en-Y hepaticojejunostomy and gastrojejunostomy and necessary palliation consisted of laparoscopic hepaticojejunostomy alone. RESULTS: A total of 48 patients received laparoscopic surgical palliation. Morbidity rate was 33.3% and mortality was 2.08%. There was no need for late surgeries in any of the patients. CONCLUSION: Surgical laparoscopic palliation is a feasible treatment option for locally advanced pancreatic cancer. Even though metallic stents are still the best palliation method for patients with systemic disease, if stents fail, the laparoscopic approach is a viable treatment.

Changes in gastrosplenic circulation and splenic function after distal pancreatectomy with spleen preservation and splenic vessel excision.

INTRODUCTION: Distal pancreatectomy with spleen preservation and splenic vessel excision is a commonly used technique. However, it produces significant gastrosplenic circulation and splenic function changes. PURPOSE: The aim of this work was to determine the immediate consequences on gastrosplenic circulation, late consequences on splenic function, and development of varicose veins. METHODS: Thirty-five patients with pancreatic tumors and anatomical feasibility were included. Preoperative splenic circulation was evaluated by dynamic contrast-enhanced computed tomography (CT) scans. Early splenic perfusion was assessed by CT 7 days after surgery and late changes in gastrosplenic circulation 6 months after surgery. Varicose veins were evaluated by CT and endoscopy 6 months after surgery. Pitted cells and Howell-Jolly bodies were used as markers of splenic function. Postoperatory findings included changes in splenic perfusion 7 days and 6 months after surgery, development of varicose veins on CT scans and endoscopy, and detection of markers of splenic hypofunction on blood smears. RESULTS AND CONCLUSION: Seven days after surgery, 63% of patients had some degree of splenic hypoperfusion, and 6 months after surgery, 83% of patients had normal perfusion. CT scans showed varices in 26 patients, and endoscopy revealed varicose veins in 11. Two patients experienced bleeding; markers of splenic hypofunction were found in 59% of cases.
