Minimally invasive techniques have improved post-operative outcomes, however, the majority of pancreatic surgery, known for its complexity, is still performed via open approaches. The development of robotics has improved dexterity which may allow for application in more complex surgeries. We queried a prospectively maintained robotic database to identify patients who underwent robotic pancreatic resection by a single surgeon between 2012 and 2016. Patient demographics and operative outcomes were compared using Mann-Whitney U, Kruskal Wallis and Pearson's Chi-square test as appropriate. We identified 119 patients; 65 Whipples [Robotic Whipple (RW)], 43 distal pancreatectomies, 4 total pancreatectomies, 6 pancreatic enucleations, and 1 robotic cyst gastrostomy with a median age of 71 [24-91], median body mass index (BMI) of 27.6 (16.8-40.2), and American society of anesthesiologists (ASA) of 3. The median estimated blood loss (EBL) was 125 [25-800] and loss of heterozygosity (LOH) 6 [1-34]. Mean operative time for RW decreased after 15 cases (578 vs. 457 minutes, P<0.004). Conversions to open occurred in 5 (4.2%) patients. In total of 117 (98.3%) patients underwent R0 resections and the median lymph node (LN) harvest was 16 [0-37]. The 30 and 90 days mortality was 1 (0.8%). Major complications (Clavien-Dindo grade 3-5) were seen in 16 (13.4%) cases (20.3%) but decreased steadily as volume increased (case 30). Pancreatic leaks occurred in 14 (11.8%): A, 8 (6.7%); B, 4 (3.4%); and C, 2 (1.7%). Robotic assisted approaches to pancreatic resections is feasible. However, it takes approximately 15 cases before a decrease in operative time and 30 cases before major complications are decreased. These trends in complications are associated with surgeon experience and volume are critical to consider in robotic pancreatic surgery.

We have come a long way from the onset of surgery for esophageal cancer. Surgical resection is pivotal for the long-term survival in patients with locally advanced esophageal cancer. Moreover, advancements in post-operative care and surgical techniques have contributed to reductions in morbidity. More recently minimally invasive esophagectomy has been increasingly used in patients undergoing esophageal cancer resection. Potential advantages of MIE include: the decreased pulmonary complications, lower post-operative wound infection, decreased post-operative pain, and decreased length of hospitalization. The application of robotics to esophageal surgery is becoming more widespread. Robotic esophageal surgery has potential advantages over the known limitations of laparoscopic and thoracoscopic approaches to esophagectomy while adhering to the benefits of the minimally invasive approach. This paper is a review of the evolution from open esophagectomy to the most recent robotic approach.

Background: We sought to examine the impact of neoadjuvant chemotherapy (NCT), single agent or multiagent chemotherapy, and neoadjuvant chemoradiation (NCRT) on survival in pancreatic cancer. Methods: Utilizing the National Cancer Database, we identified patients who underwent pancreatic resection for adenocarcinoma (2006 to 2013). Overall survival (OS) analysis was performed using the Kaplan-Meier method. Multivariable cox proportional hazard models (MVA) and propensity score matching (PSM) were developed to identify predictors of survival. For upfront surgery (UFS), OS was limited to receipt of adjuvant treatment. Results: We identified 26,563 patients who underwent pancreatic resection: UFS =23,877, NCRT =1,482, and NCT =1,204. Multiagent chemotherapy was utilized in 77% of NCT and 42% of NCRT. There was improved R0 resections associated with neoadjuvant therapy compared to UFS, however, there was no difference between NCT and NCRT. In addition, the was improved R0 with MA-NCT (P<0.001) but not for single agent NCT (P=0.26). After PSM, the median OS for UFS, SA-NCT, MA-NCT, SA-NCRT,
