Abstract
This study was designed to demonstrate non-inferiority of robot-assisted total pancreatectomy (RATP) to open total pancreatectomy (OPT) based on an intention-to-treat analysis, having occurrence of severe post-operative complications (SPC) as primary study endpoint. The two groups were matched (2:1) by propensity scores. Assuming a rate of SPC of 22.5% (non-inferiority margin: 15%; α: 0.05; β: 0.20; power: 80%), a total of 25 patients were required per group. During the study period (October 2008–December 2019), 209 patients received a total pancreatectomy. After application of exclusion and inclusion criteria, matched groups were extracted from an overall cohort of 132 patients (OPT: 107; RATP: 25). Before matching, the two groups were different with respect to prevalence of cardiac disease (24.3% versus 4.0%; p = 0.03), presence of jaundice (45.8% versus 12.0%; p = 0.002), presence of a biliary drainage (23.4% versus 0; p = 0.004), history of weight loss (28.0% versus 8.0%; p = 0.04), and vein involvement (55.1% versus 28.0%) (p = 0.03). After matching, the two groups (OTP: 50; RATP: 25) were well balanced. Regarding primary study endpoint, SPC developed in 13 patients (26.0%) after OTP and in 6 patients (24.0%) after RATP (p = 0.85). Regarding secondary study endpoints, RATP was associated with longer median operating times [475 (408.8–582.5) versus 585 min (525–637.5) p = 0.003]. After a median follow-up time of 23.7 months (10.4–71), overall survival time [22.6 (11.2–81.2) versus NA (27.3–NA) p = 0.006] and cancer-specific survival [22.6 (11.2–NA) versus NA (27.3–NA) p = 0.02] were improved in patients undergoing RATP. In carefully selected patients, robot-assisted total pancreatectomy is non-inferior to open total pancreatectomy regarding occurrence of severe post-operative complications.

Abstract
Minimally invasive surgical approaches in transplantation are gaining increasing interest, and many centers are reporting their, mainly laparoscopic, experiences. Robotic surgery (RS) has some hypothetical advantages over traditional laparoscopy and has been successfully applied, although infrequently to organ transplantation. Our goal was to review and critique the publications reporting RS use in organ transplantation. Most of the RS experience has been with living renal donor organ procurement and, to a lesser extent, with RS procedures in the transplant recipient. The available literature suggests that RS appears to be a safe surgical alternative to standard open procedures. RS in living liver donor surgery remains limited, and more experience is required before commenting on RS-related outcomes RS in pancreatic transplantation is exceedingly rare. The enhanced precision and ergonomics of RS may expand its applicability to liver living donation and pancreas transplantation at some point in the future.

Abstract
RATIONALE Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. PATIENTS AND METHODS Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien-Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. DIAGNOSIS AND OUTCOMES The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450-540 minutes), the mean estimated blood loss was 266 mL (range 100-400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8-24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. LESSONS Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy.

Abstract
Pancreatic surgery is one of the most technically challenging and complex types of surgery. Most pancreatic surgery is performed with the open technique, yet minimally invasive surgery has become the standard of care for many other intra-abdominal operations. The unique qualities of the robotic platform have made this approach to pancreatic surgery safe and feasible with at least equivalent if not better results than the open platform in terms of surgical and oncological outcomes.

Abstract
Pancreatic cancer is the 4th leading cause of cancer-related death in Western countries. Considering the low incidence of pancreatic cancer, population-based screening is not feasible. However, the existence of a group of individuals with an increased risk to develop pancreatic cancer has been well established. In particular, individuals suffering from a somatic or genetic condition associated with an increased relative risk of more than 5- to 10-fold seem to be suitable for enrollment in a surveillance program for prevention or early detection of pancreatic cancer. The aim of such a program is to reduce pancreatic cancer mortality through early or preemptive surgery. Considering the risk associated with pancreatic surgery, the concept of preemptive surgery cannot consist of a prophylactic removal of the pancreas in high-risk healthy individuals, but must instead aim at treating precancerous lesions such as intraductal papillary mucinous neoplasms or pancreatic intraepithelial neoplasms, or early cancer. Currently, results from clinical trials do not convincingly demonstrate the efficacy of this approach in terms of identification of precancerous lesions, nor do they define the outcome of the surgical treatment of these lesions. For this reason, surveillance programs for individuals at risk of pancreatic cancer are thus far generally limited to the setting of a clinical trial. However, the acquisition of a deeper understanding of this complex area, together with the increasing request for screening and treatment by individuals at risk, will usher pancreatologists into a new era of preemptive pancreatic surgery. Along with the growing demand to treat individuals with precancerous lesions, the need for low-risk investigation, low-morbidity operation and a minimally invasive approach becomes increasingly pressing. All of these considerations are reasons for preemptive pancreatic surgery programs to be undertaken in specialized centers only.

Abstract
BACKGROUND The enhanced dexterity offered by robotic assistance could be excessive for distal pancreatectomy but not enough to improve the outcome of laparoscopic pancreaticoduodenectomy. Total pancreatectomy retains the challenges of uncinate process dissection and digestive reconstruction, but avoids the risk of pancreatic fistula, and could be a suitable operation to highlight the advantages of robotic assistance in pancreatic resections. METHODS Eleven laparoscopic robot-assisted total pancreatectomies (LRATP) were compared to 11 case-matched open total pancreatectomies. All operations were performed by one surgeon during the same period of time. Robotic assistance was employed in half of the patients, based on robot availability at the time of surgery. Variables examined included age, sex, American Society of Anesthesiologists score, body mass index, estimated blood loss, need for blood transfusions, operative time, tumor type, tumor size, number of examined lymph nodes, margin status, post-operative complications, 90-day or in-hospital mortality, length of hospital stay, and readmission rate. RESULTS No LRATP was converted to conventional laparoscopy, hand-assisted laparoscopy or open surgery despite two patients (18.1 %) required vein resection and reconstruction. LRATP was associated with longer mean operative time (600 vs. 469 min; p = 0.014) but decreased mean blood loss (220 vs. 705; p = 0.004) than open surgery. Post-operative complications occurred in similar percentages after LRATP and open surgery. Complications occurring in most patients (5/7) after LRATP were of mild severity (Clavien-Dindo grade I and II). One patient required repeat laparoscopic surgery after LRATP, to drain a fluid collection not amenable to percutaneous catheter drainage. One further patient from the open group required repeat surgery because of bleeding. No patient had margin positive resection, and the mean number of examined lymph nodes was 45 after LRATP and 36 after open surgery. CONCLUSIONS LRATP is feasible in selected patients, but further experience is needed to draw final conclusions.

Abstract
The goal of IAT is the preservation of beta-cell mass at the time of pancreatectomy. The majority of recipients have significant endogenous beta-cell function with positive blood C-peptide after surgery, even if only approximately one third achieve insulin independence. In appropriately selected patients, total pancreatectomy combined with IAT achieves relief of pain and improves quality of life with relatively easier-to-manage glycemic control and avoidance of hyper- and hypoglycemic episodes. Current research is focused on improving techniques of islet isolation and engraftment as well as long-term survival of autografted islets.

Abstract
INTRODUCTION Because of the potential benefit of robotics in pancreatic surgery, we review our experience at two minimally invasive pancreatic surgery centers that utilize a robotically controlled laparoscope holder to see if smaller robots that enable the operating surgeon to maintain contact with the patient may have a role in the treatment of pancreatic disease. METHODS From March 1994 to June 2011, a total of 200 laparoscopic pancreatic procedures utilizing a robotically controlled laparoscope holder were performed. RESULTS A total of 72 duodenopancreatectomies, 67 distal pancreatectomies, 23 enucleations, 20 pancreatic cyst drainage procedures, 5 necrosectomies, 5 atypical pancreatic resections, 4 total pancreatectomies, and 4 central pancreatectomies were performed. Fourteen patients required conversion to an open approach and eight a hand-assisted one. A total of 24 patients suffered a major complication. Sixteen patients developed a pancreatic leak and 19 patients required reoperation. Major complications occurred in 14 patients and pancreatic leaks occurred in 13 patients. Ten patients required conversion to a lap-assisted or open approach and six patients required reoperation. CONCLUSIONS Currently, a robotically assisted approach using a camera holder seems the only way to incorporate some of the benefits of robotics in pancreatic surgery while maintaining haptics and contact with the patient.

Abstract
For patients with severe chronic pancreatitis refractory to medical interventions, total pancreatectomy can be considered to relieve the root cause of pain. The goal of a simultaneous islet autotransplant is to prevent or minimize the otherwise inevitable surgical diabetes. Islet autotransplant can successfully preserve some endogenous islet function in the majority of recipients, which mediates protection against brittle diabetes. Most maintain reasonably good glycemic control, while 30 %-40 % successfully discontinue insulin therapy. With islet autotransplants reaching a wider clinical audience, refinements in islet isolation techniques and strategies to protect islet grafts post-transplant may further improve the success of this procedure.

Abstract
UNLABELLED Pancreatic tumours are a serious medical and social issue. Patients come to the doctor too late, when the disease is well advanced. The most frequently applied method of surgical treatment is pancreatoduodenectomy (Whipple procedure). The most frequently used technique of pancreatoduodenectomy is the Child-Waugh method. The procedure can be performed in a classic way or as modified by Traverso (with preservation of the pylorus). MATERIAL AND METHODS Between August 2008 and June 2011, in the Department of Thoracic, General and Oncologic Surgery of Medical University in Łódź, a total of 79 patients with pancreatic tumours were hospitalized. In 61, pancreatoduodenectomy was performed. The patients were divided into two groups, depending on the diagnosis and the procedures performed: group 1 comprised patients in whom the pylorus was resected (n = 43); group 2 comprised patients in whom the pylorus was preserved (Traverso-Longmire procedure; n = 18). RESULTS Mean duration of surgery was about 3 hours and 50 minutes in both groups. Mean duration of hospitalization after the procedure was 15.6 days in group 1 and 12.2 days in group 2 (p < 0.05). Early complications (within 30 days of the procedure) were observed in 33.2% of patients in both groups. Blood transfusion was necessary in 21% of patients in group 1 and 28% of patients in group 2 (p>0.05). CONCLUSIONS There are specific indications for each method of surgical treatment, however, it seems that both techniques of pancreatic resection can be recommended as standard surgical treatment, and the number of complications after both procedures is similar.

Abstract
BACKGROUND Total pancreatectomy (TP) with intraportal islet autotransplantation (IAT) can relieve pain and preserve β-cell mass in patients with chronic pancreatitis (CP) when other therapies fail. We report on a >30-year single-center series. STUDY DESIGN Four hundred and nine patients (including 53 children, 5 to 18 years) with CP underwent TP-IAT from February 1977 to September 2011 (etiology: idiopathic, 41%; Sphincter of Oddi dysfunction/biliary, 9%; genetic, 14%; divisum, 17%; alcohol, 7%; and other, 12%; mean age was 35.3 years, 74% were female; 21% has earlier operations, including 9% Puestow procedure, 6% Whipple, 7% distal pancreatectomy, and 2% other). Islet function was classified as insulin independent for those on no insulin; partial, if known C-peptide positive or euglycemic on once-daily insulin; and insulin dependent if on standard basal-bolus diabetic regimen. A 36-item Short Form (SF-36) survey for quality of life was completed by patients before and in serial follow-up since 2007, with an integrated survey that was added in 2008. RESULTS Actuarial patient survival post TP-IAT was 96% in adults and 98% in children (1 year) and 89% and 98% (5 years). Complications requiring relaparotomy occurred in 15.9% and bleeding (9.5%) was the most common complication. IAT function was achieved in 90% (C-peptide >0.6 ng/mL). At 3 years, 30% were insulin independent (25% in adults, 55% in children) and 33% had partial function. Mean hemoglobin A1c was <7.0% in 82%. Earlier pancreas surgery lowered islet yield (2,712 vs 4,077/kg; p = 0.003). Islet yield (<2,500/kg [36%]; 2,501 to 5,000/kg [39%]; >5,000/kg [24%]) correlated with degree of function with insulin-independent rates at 3 years of 12%, 22%, and 72%, and rates of partial function 33%, 62%, and 24%. All patients had pain before TP-IAT and nearly all were on daily narcotics. After TP-IAT, 85% had pain improvement. By 2 years, 59% had ceased narcotics. All children were on narcotics before, 39% at follow-up; pain improved in 94%; and 67% became pain-free. In the SF-36 survey, there was significant improvement from baseline in all dimensions, including the Physical and Mental Component Summaries (p < 0.01), whether on narcotics or not. CONCLUSIONS TP can ameliorate pain and improve quality of life in otherwise refractory CP patients, even if narcotic withdrawal is delayed or incomplete because of earlier long-term use. IAT preserves meaningful islet function in most patients and substantial islet function in more than two thirds of patients, with insulin independence occurring in one quarter of adults and half the children.

All children were on narcotics before, 39% at follow-up; pain improved in 94%; and 67% became pain-free. In the SF-36 survey, there was significant improvement from baseline in all dimensions, including the Physical and Mental Component Summaries (p < 0.01), whether on narcotics or not. CONCLUSIONS TP can ameliorate pain and improve quality of life in otherwise refractory CP patients, even if narcotic withdrawal is delayed or incomplete because of earlier long-term use. IAT preserves meaningful islet function in most patients and substantial islet function in more than two thirds of patients, with insulin independence occurring in one quarter of adults and half the children.
