Long-term recurrence after endoscopic versus surgical ampullectomy of sporadic ampullary adenomas: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Ampullary adenomas are treated both surgically and endoscopically, however, data comparing both techniques are lacking. We aimed to compare long-term recurrence of benign sporadic adenomas after endoscopic (EA) and surgical ampullectomy (SA). METHODS: A comprehensive literature search of multiple databases (until December 29, 2020) was performed to identify studies reporting outcomes of EA or SA of benign sporadic ampullary adenomas. The outcome was recurrence rate at 1 year, 2-year, 3 year and 5 years after EA and SA. RESULTS: A total of 39 studies with 1753 patients (1468 EA [age 61.1 ± 4.0 years, size 16.1 ± 4.0 mm], 285 SA [mean age 61.6 ± 4.48 years, size 22.7 ± 5.4 mm]) were included in the analysis. At year 1, pooled recurrence rate of EA was 13.0% (95% confidence interval [CI] 10.5-15.9], I2 = 31%) as compared to SA 14.1% (95% CI 9.5-20.3 I2 = 15.8%) (p = 0.82). Two (12.5%, [95% CI, 8.9-17.2] vs. 14.3 [95% CI, 9.1-21.6], p = 0.63), three (13.3%, [95% CI, 7.3-21.6] vs. 12.9 [95% CI, 7.3-21.6], p = 0.94) and 5 years (15.7%, [95% CI, 7.8-29.1] vs. 17.6% [95% CI, 6.2-40.8], p = 0.85) recurrence rate were comparable after EA and SA. On meta-regression, age, size of lesion or enbloc and complete resection were not significant predictors of recurrence. CONCLUSION: EA and SA of sporadic adenomas have similar recurrence rates at 1, 2, 3 and 5 years of follow up.

Portal vein reconstruction during pancreaticoduodenal resection using an internal jugular vein as a graft.

Portal vein involvement by malignant tumours of the head of the pancreas is observed in almost 50% of the patients. In the past, this finding usually rendered the tumor inoperable. Over the past 30 years, the operative morbidity and mortality rate of pancreatectomy combined with portal vein resection has greatly decreased, and portal vein resection in pancreatic surgery has become a well-tolerated operative procedure in large-volume centres. Options for a venous reconstruction after SMV/PV resection include prosthetic, autologous or cryopreserved cadaveric vein grafts.Vascular resection and reconstruction provides great opportunity for R0 resection and improvement of oncological results in patients with pancreatic tumors and involvement of venous vessels, in the absence of distant metastases. If a longer graft length is required, there is the option of using either synthetic prosthesis or cryopreserved grafts. Their weak sides can be avoided by the use of jugular vein graft. Portal vein resection will be performed more often, safely and aggressively over the next years.

Rare, Uncommon, and Unusual Complications After Pancreaticoduodenal Resection.

Complications after pancreaticoduodenal resection occur in at least 30% of patients. Most are a direct result of an intraoperative event, dissection, or anastomoses which account for the most serious morbidities, sepsis, pseudoaneurysms, and hemorrhage. Rarely, complications are due to the systemic impact of the procedure even if the procedure itself was unremarkable. Rare systemic complications after PDR (Transfusion transmitted Babesiosis, pituitary apoplexy, and TRALI) and a number of uncommon and unusual other complications are discussed. Pancreaticoduodenal resection is a significant operation with serious consequences. Decisions on selection of candidates and safe operations should be thoughtful and always in surgeons' minds.

Cancer of the Pancreas-Actual 5, 10, and 20+Year Survival: The Lucky and Fortunate Few.

Cancer of the pancreas (CaP) is a dismal, uncommon, systemic malignancy. This article updates an earlier experience of actual long-term survival of CaP in patients treated between 1991 to 2000, and reviews the literature. Survival is expressed as actual, not projected, survival.
