RESUMEN
BACKGROUND: The impact of cirrhosis on the postoperative outcomes of distal pancreatectomy is yet to be reported. We aimed to evaluate the outcomes of distal pancreatectomy in patients with cirrhosis. METHODS: We conducted a retrospective, multicentric study patients with cirrhosis who underwent planned distal pancreatectomy between 2008 and 2020 in French high volume centers. Patients with cirrhosis were matched 1:4 for demographic, surgical, and histologic criteria with patients without cirrhosis. The primary endpoint was severe morbidity (Clavien-Dindo grade ≥III). The secondary endpoints were postoperative complications, specifically related to cirrhosis and pancreatic surgery, and survival for patients with pancreatic adenocarcinoma. RESULTS: Overall, 32 patients with cirrhosis were matched with 128 patients without cirrhosis. Most patients (93.5%) had Child-Pugh A cirrhosis. The severe morbidity rate after distal pancreatectomy was higher in patients with cirrhosis than in those without cirrhosis (28.13% vs 25.75%, P = .11. The operative time was significantly longer in the cirrhotic group compared with controls (P = .01). However, patients with and without cirrhosis had comparable blood loss and conversion rates. Postoperatively, the two groups had similar rates of pancreatic fistula, hemorrhage, reoperation, postoperative mortality, and survival rates at 1, 3, and 5 years. CONCLUSION: The current study suggests that distal pancreatectomy in high-volume centers is feasible for patients with compensated cirrhosis.

BACKGROUND: Minimally invasive surgery has gained momentum for left pancreatic resections. However, debate remains about whether it has any advantage over open surgery for distal pancreatectomy for pancreatic neuroendocrine tumors. METHODS: This retrospective review examined pancreatectomies performed for resectable pancreatic neuroendocrine tumors at 21 centers in France between January 2014 and December 2018. Short and long-term outcomes were compared before and after propensity score matching based on tumor size, sex, age, body mass index, center, and method of pancreatic transection. RESULTS: During the period study, 274 patients underwent left pancreatic resection for pancreatic neuroendocrine tumors [109 underwent distal splenopancreatectomy, and 165 underwent spleen-preserving distal pancreatectomy [(splenic vessel preservation (n = 97; 58.7%)/splenic vessel resection (n = 68; 41.3%)]. Before propensity score matching, minimally invasive surgery was associated with a lower rate of major morbidity (P = .004), lower rate of postoperative delayed gastric emptying (P = .04), and higher rate of "textbook" outcomes (P = .04). After propensity score matching, there were 2 groups of 54 patients (n = 30 distal splenopancreatectomy; n = 78 spleen-preserving distal pancreatectomy). Minimally invasive surgery was associated with less blood loss (P = .05), decreased rate of major morbidity (6% vs. 24%; P = .02), less delayed gastric emptying (P = .05) despite similar rates of postoperative fistula, hemorrhage, and reoperation (P > .05). The 5-year overall survival (79% vs. 75%; P = .74) and recurrence-free survival (10% vs 17%; P = .39) were similar. CONCLUSION: Minimally invasive surgery for left pancreatic resection can be safely proposed for patients with resectable left pancreatic neuroendocrine tumors. Minimally invasive surgery decreases the rate of major complications while providing comparable long-term oncologic outcomes.

Background: Brain metastases (BM) are rare in pancreatic ductal adenocarcinoma (PDAC) and little data exists concerning these patients and their outcomes. Aim: We aimed to analyze the management, practices, and outcomes of patients presenting BM from PDAC both in our institution and in all cases reported in the literature. Methods: We conducted a retrospective, monocentric analysis using a data mining tool (ConSoRe) to identify all patients diagnosed with PDAC and BM in our comprehensive cancer center (Paoli-Calmettes Institute), from July 1997 to June 2022 (cohort 1). Simultaneously, we reviewed and pooled the case reports and case series of patients with PDAC and BM in the literature (cohort 2). The clinical characteristics of patients in each cohort were described and survival analyses were performed using the Kaplan-Meier method. Results: In cohort 1, 19 patients (0.3%) with PDAC and BM were identified with a median age of 69 years (range: 39-81). Most patients had metastatic disease (74%), including 21% with BM, at diagnosis. Lung metastases were present in 58% of patients. 68% of patients had neurological symptoms and 68% were treated by focal treatment (surgery: 21%, radiotherapy: 42%, Gamma Knife radiosurgery: 5%). In cohort 2, among the 61 PDAC patients with BM described in the literature, 59% had metastatic disease, including 13% with BM at diagnosis. Lung metastases were present in 36% of patient and BM treatments included: surgery (36%), radiotherapy (36%), radiosurgery (3%), or no local treatment (25%). After the pancreatic cancer diagnosis, the median time to develop BM was 7.8 months (range: 0.0-73.9) in cohort 1 and 17.0 months (range: 0.0-64.0) in cohort 2. Median overall survival (OS) in patients of cohort 1 and cohort 2 was 2.9 months (95% CI [1.7,4.0]) and 12.5 months (95% CI [7.5,17.5]), respectively. Conclusion: BM are very uncommon in PDAC and seem to occur more often in younger patients with lung metastases and more indolent disease. BM are associated with poor prognosis and neurosurgery offers the best outcomes and should be considered when feasible.
