Clinicopathologic Analysis and Prognostic Factors for Survival in Patients with Operable Ampullary Carcinoma: A Multi-Institutional Retrospective Experience.

Background and Objectives: In ampullary cancer, 5-year survival rates are 30-50%, even with optimal resection and perioperative systemic therapies. We sought to determine the important clinicopathological features and adjuvant treatments in terms of the prognosis of patients with operable-stage ampullary carcinomas. Materials and Methods: We included 197 patients who underwent pancreaticoduodenectomy to treat ampullary carcinomas between December 2003 and May 2019. Demographics, clinical features, treatments, and outcomes/survival were analyzed. Results: The median disease-free survival (mDFS) and median overall survival (mOS) were 40.9 vs. 63.4 months, respectively. The mDFS was significantly lower in patients with lymphovascular invasion (p < 0.001) and lymph node involvement (p = 0.027). Potential predictors of decreased OS on univariate analysis included age ≥ 50 years (p = 0.045), poor performance status (p = 0.048), weight loss (p = 0.045), T3-T4 tumors (p = 0.018), surgical margin positivity (p = 0.01), lymph node involvement (p = 0.001), lymphovascular invasion (p < 0.001), perineural invasion (p = 0.007), and poor histological grade (p = 0.042). For the multivariate analysis, only nodal status (hazard ratio [HR]1.98; 95% confidence interval [CI], 1.08-3.65; p = 0.027) and surgical margin status (HR 2.61; 95% CI, 1.09-6.24; p = 0.03) were associated with OS. Conclusions: Nodal status and a positive surgical margin were independent predictors of a poor mOS for patients with ampullary carcinomas. Additional studies are required to explore the role of adjuvant therapy in patients with ampullary carcinomas.

Short­ and long­term outcomes after laparoscopic and open pancreatoduodenectomy for elderly patients: a propensity score­matched study.

BACKGROUND: The feasibility and safety of laparoscopic pancreatoduodenectomy (LPD) in elderly patients is still controversial. This study aimed to compare the clinical outcomes of LPD and open pancreatoduodenectomy (OPD) in elderly patients. METHODS: Clinical and follow-up data of elderly patients (≥ 65 years) who underwent LPD or OPD between 2015 and 2022 were retrospectively analyzed. A 1:1 propensity score-matching (PSM) analysis was performed to minimize differences between groups. Univariate and multivariate logistic regression analysis were used to select independent prognostic factors for 90-day mortality. RESULTS: Of the 410 elderly patients, 236 underwent LPD and 174 OPD. After PSM, the LPD group had a less estimated blood loss (EBL) (100 vs. 200 mL, P < 0.001), lower rates of intraoperative transfusion (10.4% vs. 19.0%, P = 0.029), more lymph node harvest (11.0 vs. 10.0, P = 0.014) and shorter postoperative length of stay (LOS) (13.0 vs. 16.0 days, P = 0.013). There were no significant differences in serious complications, reoperation, 90-day readmission and mortality rates (all P > 0.05). Multivariate logistic regression analysis showed that post-pancreatectomy hemorrhage (PPH) was an independent risk factor for 90-day mortality. Elderly patients with pancreatic ductal adenocarcinoma (PDAC) who underwent LPD or OPD had similar overall survival (OS) (22.5 vs.20.4 months, P = 0.672) after PSM. CONCLUSIONS: It is safe and feasible for elderly patients to undergo LPD with less EBL and a shorter postoperative LOS. There was no statistically significant difference in long-term survival outcomes between elderly PDAC patients who underwent LPD or OPD.

Feasibility of middle colic artery as a landmark for superior mesenteric artery - first approach in laparoscopic pancreatoduodenectomy: a prospective study.

BACKGROUND: SMA-first approach in pancreatoduodenectomy (PD) has been widely applied in open surgery as well as laparoscopy. Finding the superior mesenteric artery (SMA), inferior pancreatoduodenal artery (IPDA), first jejunal artery (J1A) has become a great challenge in laparoscopic PD (LPD). Meanwhile, exposing the midde colic artery (MCA) might be a feasible approach to determine SMA, IPDA, and J1A. Our study aims to find the anatomical correlation between MCA and SMA, IPDA, J1A, especially in SMA-first approach LPD from the left. METHODS: Uncontrolled clinical trial with 33 patients undergoing LPD had preoperative contrast abdominal CT scan to analyze the anatomical relevance between MCA and SMA, J1A, IPDA. The operation was performed starting with exposing MCA in advance to find SMA, J1A and IPDA. The data was analyzed by SPSS 25.0. RESULTS: 90.9% of MCA started at 12-3 o'clock from SMA, the mean distance from the SMA root to the MCA and J1A was 56.4 mm and 37.4 mm, respectively. The distance between SMA and J1A was 19 mm. 72.7% J1A started at 9-12 o'clock, 69.7% J1A and IPDA had a common trunk. 78.8% IPDA started at 3-6 o'clock. 100% of the cases had J1A controlled intraoperatively, 81.8% for IPDA when approached from the left, 3% had MCA injury. The mean time to approach from the left was 98 min, median blood loss was 100 ml. CONCLUSION: Exposing MCA first helps determine SMA, J1A and IPDA safely, efficiently and faciliates SMA-first approach LPD from the left and complete dissection of the mesopancreas and lymph nodes.

What are the true benefits of robotic pancreaticoduodenectomy for patients with pancreatic cancer?

INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease, and multimodal treatment including high-quality surgery can improve survival outcomes. Pancreaticoduodenectomy (PD) has evolved with minimally invasive approaches including the implementation of robotic PD (RPD). In this special report, we review the literature whilst evaluating the 'true benefits' of RPD compared to open approach for the treatment of PDAC. AREAS COVERED: We have performed a mini-review of studies assessing PD approaches and compared intraoperative characteristics, perioperative outcomes, post-operative complications and oncological outcomes. EXPERT OPINION: RPD was associated with similar or longer operative times, and reduced intra-operative blood loss. Perioperative pain scores were significantly lower with shorter lengths of stay with the robotic approach. With regards to post-operative complications, post-operative pancreatic fistula rates were similar, with lower rates of clinically relevant fistulas after RPD. Oncological outcomes were comparable or superior in terms of margin status, lymph node harvest, time to chemotherapy and survival between RPD and OPD. In conclusion, RPD allows safe implementation of minimally invasive PD. The current literature shows that RPD is either equivalent, or superior in certain aspects to OPD. Once more centers gain sufficient experience, RPD is likely to demonstrate clear superiority over alternative approaches.

Impact on Long-term Survival of a Standardized Histopathological Protocol on the R1 Incidence in Pancreatoduodenectomy for Pancreatic Ductal Adenocarcinoma.

Background: Pancreatic Ductal Adenocarcinoma (PDAC) is a pathology with a very poor prognostic, the only curative treatment option being surgery, in association with chemotherapy. This study aims to assess the influence that the use of a standardized pathology report after a pancreaticoduodenectomy (PD) has on the R1 margins rate and the impact that this has on long term survival. Material and Methods: We included 116 patients admitted to the Regional Institute of Gastroenterology and Hepatology Prof. Dr. O. Fodor Cluj Napoca, who underwent PD for PDAC (Pancreatic Ductal Adenocarcinoma) between January 2012 and May 2017. We divided them in two groups: 59 patients for which a nonstandardized histopathological protocol was used and 57 patients for which a standardized protocol was implemented. We considered a margin to be R1 when there were tumor cells at ¤ 1 mm from the resection margin. Results: The R1 percentage in the first group of patients was of 39%, while the R1 resection rate in the second group was of 68.4%. The median survival rate was similar in the two groups, with no statistically significant difference between them, but in the prospective study when comparing R0 vs R1 margins there was a statistically differences in 5 year OS with a p-value = 0.03. Conclusion: The use of a standardized pathology report reveals a significant increase in R1 resection rates. Also study revealed not only increasing R1 incidence when using a standardized histopathology report, but also that those margins (R1) playing a determinant role in 5-year OS. The mesopancreas is the most frequently R1 resection margin.

Pancreatoduodenectomy combined with intestinal de-rotation as a complete artery-first approach for inexperienced surgeons.

BACKGROUND: Recent technical advances have reduced the incidence of intraoperative complications associated with pancreatoduodenectomy (PD). We aimed to determine whether inexperienced surgeons (ISs) would be as successful as experienced surgeons (ESs) when performing the complete artery-first approach using the intestinal de-rotation method of PD. METHODS: Seventy patients who underwent PD using the intestinal de-rotation method in Tokushima University Hospital were enrolled in the present study. Intra- and post-operative parameters were compared between patients operated on by ESs (n=20) or ISs (n=50). RESULTS: The surgical procedure lasted longer in the IS group (ES : 402 }68 min vs. IS : 483 }51 min, p<0.0001), but the volume of blood loss was similar (p=0.7304). There was no mortality in either group, and the incidences of postoperative complications with a Clavien-Dindo grade of>III did not differ between the groups. Grade B postoperative pancreatic fistulae developed in 20.0% of patients in the ES group and 22.0% in the IS group (p=0.9569). Finally, the postoperative hospital stay of the IS group (32 }33 days) was equivarent to that of the ES group (33 }16 days) (p=0.9256). CONCLUSION: ISs were able to perform similarly successful PDs using the intestinal de-rotation method to ESs. J. Med. Invest. 71 : 75-81, February, 2024.

Laparoscopic Pancreaticoduodenectomy Combined With Portal-Superior Mesenteric Vein Resection and Reconstruction: Inferior-Posterior "Superior Mesenteric Artery-First" Approach.

BACKGROUND: Laparoscopic pancreaticoduodenectomy (LPD) with portal-superior mesenteric vein (PV/SMV) resection and reconstruction is increasingly performed. We aimed to introduce a safe and effective surgical approach and share our clinical experience with LPD with PV/SMV resection and reconstruction. METHODS: We reviewed data for the patients undergoing LPD and open pancreaticoduodenectomy (OPD) combined with PV/SMV resection and reconstruction at the First Hospital of Jilin University between April 2021 and May 2023. The inferior-posterior "superior mesenteric artery-first" approach was used. We compared the preoperative, intraoperative, and postoperative clinicopathological data of the 2 groups to conduct a comprehensive evaluation of LPD with major vascular resection. RESULTS: A cohort of 37 patients with periampullary and pancreatic tumors underwent pancreaticoduodenectomy (PD) with major vascular resection and reconstruction, consisting of 21 LPDs and 16 OPDs. The LPD group had a longer operation time (322 vs. 235 min, P =0.039), reduced intraoperative bleeding (152 vs. 325 mL, P =0.026), and lower intraoperative blood transfusion rates (19.0% vs. 50.0%, P =0.046) compared with the OPD group. The LPD group had significantly shorter operation times in end-to-end anastomosis (26 vs. 15 min, P =0.001) and artificial grafts vascular reconstruction (44 vs. 22 min, P =0.000) compared with the OPD group. There was no significant difference in the rate of R0 resection (100% vs. 87.5%, P =0.096). The length of hospital stay and ICU stay did not show significant differences between the 2 groups (15 vs. 18 d, P =0.636 and 2.5 vs. 4.5 d, P =0.726, respectively). However, the postoperative hospital stay in the LPD group was notably shorter compared with the OPD group (11 vs. 16 d, P =0.007). Postoperative complication rates, including postoperative pancreatic fistula (POPF) Grade A/B, biliary leakage, and delayed gastric emptying (DGE), were similar between the two groups (38.1% vs. 43.8%, P =0.729). In addition, 1 patient in each group developed thrombosis, with vascular patency improving after anticoagulation treatment. CONCLUSION: LPD combined with PV/SMV resection and reconstruction can be easily and safely performed using the inferior-posterior "superior mesenteric artery-first" approach in cases of venous invasion. Further studies are required to evaluate the procedure's long-term outcomes.

Effect of artificial or autologous coverage of the pancreatic remnant or anastomosis on postoperative pancreatic fistulas after partial pancreatectomy: meta-analysis of randomized clinical trials.

BACKGROUND: Postoperative pancreatic fistulas remain a driver of major complications after partial pancreatectomy. It is unclear whether coverage of the anastomosis or pancreatic remnant can reduce the incidence of postoperative pancreatic fistulas. The aim of this study was to evaluate the effect of autologous or artificial coverage of the pancreatic remnant or anastomosis on outcomes after partial pancreatectomy. METHODS: A systematic literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) up to March 2024. All RCTs analysing a coverage method in patients undergoing partial pancreatoduodenectomy or distal pancreatectomy were included. The primary outcome was postoperative pancreatic fistula development. Subgroup analyses for pancreatoduodenectomy or distal pancreatectomy and artificial or autologous coverage were conducted. RESULTS: A total of 18 RCTs with 2326 patients were included. In the overall analysis, coverage decreased the incidence of postoperative pancreatic fistulas by 29% (OR 0.71, 95% c.i. 0.54 to 0.93, P < 0.01). This decrease was also seen in the 12 RCTs covering the remnant after distal pancreatectomy (OR 0.69, 95% c.i. 0.51 to 0.94, P < 0.02) and the 4 RCTs applying autologous coverage after pancreatoduodenectomy and distal pancreatectomy (OR 0.53, 95% c.i. 0.29 to 0.96, P < 0.04). Other subgroup analyses (artificial coverage or pancreatoduodenectomy) showed no statistically significant differences. The secondary endpoints of mortality, reoperations, and re-interventions were each affected positively by the use of coverage techniques. The certainty of evidence was very low to moderate. CONCLUSION: The implementation of coverage, whether artificial or autologous, is beneficial after partial pancreatectomy, especially in patients undergoing distal pancreatectomy with autologous coverage.

Introduction of robotic pancreatoduodenectomy following phase 2a IDEAL guidelines.

BACKGROUND: Robotic pancreatoduodenectomy (RPD) is a newly introduced procedure, which is still evolving and lacks standardization. An objective assessment is essential to investigate the feasibility of RPD. The current study aimed to assess our initial ten cases of RPD based on IDEAL (Idea, Development, Exploration, Assessment, and Long-term study) guidelines. METHODS: This was a prospective phase 2a study following the IDEAL framework. Ten consecutive cases of RPD performed by two surgeons with expertise in open procedures at a single center were assigned to the study. With objective evaluation, each case was classified into four grades according to the achievements of the procedures. Errors observed in the previous case were used to inform the procedure in the next case. The surgical outcomes of the ten cases were reviewed. RESULTS: The median total operation time was 634 min (interquartile range [IQR], 594-668) with a median resection time of 363 min (IQR, 323-428) and reconstruction time of 123 min (IQR, 107-131). The achievement of the whole procedure was graded as A, "successful", in two patients. In two patients, reconstruction was performed with a mini-laparotomy due to extensive pneumoperitoneum, probably caused by insertion of a liver retractor from the xyphoid. Major postoperative complications occurred in two patients. One patient, in whom the jejunal limb was elevated through the Treitz ligament, had a bowel obstruction and needed to undergo re-laparotomy. CONCLUSIONS: RPD is feasible when performed by surgeons experienced in open procedures. Specific considerations are needed to safely introduce RPD.

Adjuvant chemotherapy omission after pancreatic cancer resection: a French nationwide study.

BACKGROUND: Adjuvant chemotherapy (AC) improves the prognosis after pancreatic ductal adenocarcinoma (PDAC) resection. However, previous studies have shown that a large proportion of patients do not receive or complete AC. This national study examined the risk factors for the omission or interruption of AC. METHODS: Data of all patients who underwent pancreatic surgery for PDAC in France between January 2012 and December 2017 were extracted from the French National Administrative Database. We considered "omission of adjuvant chemotherapy" (OAC) all patients who failed to receive any course of gemcitabine within 12 postoperative weeks and "interruption of AC" (IAC) was defined as less than 18 courses of AC. RESULTS: A total of 11 599 patients were included in this study. Pancreaticoduodenectomy was the most common procedure (76.3%), and 31% of the patients experienced major postoperative complications. OACs and IACs affected 42% and 68% of the patients, respectively. Ultimately, only 18.6% of the cohort completed AC. Patients who underwent surgery in a high-volume centers were less affected by postoperative complications, with no impact on the likelihood of receiving AC. Multivariate analysis showed that age ≥ 80 years, Charlson comorbidity index (CCI) ≥ 4, and major complications were associated with OAC (OR = 2.19; CI95%[1.79-2.68]; OR = 1.75; CI95%[1.41-2.18] and OR = 2.37; CI95%[2.15-2.62] respectively). Moreover, age ≥ 80 years and CCI 2-3 or ≥ 4 were also independent risk factors for IAC (OR = 1.54, CI95%[1.1-2.15]; OR = 1.43, CI95%[1.21-1.68]; OR = 1.47, CI95%[1.02-2.12], respectively). CONCLUSION: Sequence surgery followed by chemotherapy is associated with a high dropout rate, especially in octogenarian and comorbid patients.

Pancreaticoduodenectomy with Anatomical Vascular Variant in Groove Pancreatitis-A Case Report.

Groove pancreatitis represents a chronic focal form of pancreatitis affecting the zone between the pancreatic head and the duodenal "C" loop, known as the groove area. This is a rare condition that affects the pancreatic periampullary part, including the duodenum and the common bile duct, which is usually associated with long-term alcohol and tobacco misuse, and is more frequent in men than in women. The most common clinical symptoms of groove pancreatitis include weight loss, acute abdominal pain, nausea, and jaundice. This report is about a 66-year-old woman with a history of heavy smoking, presenting with weight loss, nausea, and upper abdominal pain. Contrast-enhanced computed tomography revealed the existence of chronic pancreatitis as well as the dilatation of the main pancreatic duct, a cyst of the pancreatic head, and enlargement of the biliary tract. Conservatory treatment was initiated but with no improvement of symptoms. Since endoscopic retrograde cholangiopancreatography was not possible due to the local changes, we decided to perform pancreatoduodenectomy, as surgery appears to be the single effective treatment.

Intraperitoneal prophylactic drain after pancreaticoduodenectomy: an Italian survey.

Intraperitoneal prophylactic drain (IPD) use in pancreaticoduodenectomy (PD) is still controversial. A survey was designed to investigate surgeons' use of IPD in PD patients through 23 questions and one clinical vignette. For the clinical scenario, respondents were asked to report their regret of omission and commission regarding the use of IPD elicited on a scale between 0 (no regret) and 100 (maximum regret). The threshold model and a multilevel mixed regression were applied. One hundred three (97.2%) respondents confirmed using at least two IPDs. The median regret due to the omission of IPD was 84 (67-100, IQR). The median regret due to the commission of IPD was 10 (3.5-20, IQR). The CR-POPF probability threshold at which drainage omission was the less regrettable choice was 3% (1-50, IQR). The threshold was lower for those surgeons who performed minimally invasive PD (P = 0.048), adopted late removal (P = 0.002), perceived FRS able to predict the risk (P = 0.006), and IPD able to avoid relaparotomy P = 0.036). Drain management policies after PD remain heterogeneous among surgeons. The regret model suggested that IPD omission could be performed in low-risk patients.

Deconstructing the Operative Times of Robotic Pancreaticoduodenectomy.

INTRODUCTION: Despite numerous benefits offered, robotic procedures take longer than "open" procedures. With the intent to reduce operative duration, we examined the degree each operative step contributes to operative duration in robotic pancreaticoduodenectomy. MATERIALS AND METHODS: With IRB approval, we prospectively followed 88 patients to determine the duration of robotic pancreaticoduodenectomy, and the duration of 12 key steps. Each operative step was regressed against the operation date, from most distant to most recent operation date. Data are presented as median (mean ± SD) for illustrative purposes. RESULTS: Patients were 73 (71 ± 10.2) years old; 53% were men. Total time patient spent in the operating room was 471 (488 ± 93.3) minutes. Total operative time was 399 (421 ± 90.7) minutes. Total console time was 293 (297 ± 68.0) minutes. The 3 longest portions of the operation were (1) mobilization of the specimen and specimen extraction; (2) construction of the duodenojejunostomy; and (3) closure. CONCLUSION: A third of the operative time is spent off the console. Over half of the steps required more than 20 minutes each to complete. Since robotic operations are associated with shorter LOS and without increased complication rates relative to "open" operations, salutary benefit can be gained by decreasing operative times of robotic procedures. Operative duration is an important metric that needs to be addressed. We need to target the most time-consuming steps, and break them into smaller pieces, to reach optimal efficiency and provide the benefits of decreased operative duration to the patients, hospitals, and providers.

Learning Curve of a Laparoscopic Pancreaticoduodenectomy Program at a Second Institution.

BACKGROUND: Historically, pancreaticoduodenectomy (PD) has been performed via a laparotomy, but increasingly, laparoscopic and robotic platforms are being employed for PD. Laparoscopic PD has a steep surgeon specific learning curve and programmatic elements that must be optimized. These factors may limit a surgeon who is proficient at laparoscopic PD to develop a program at another institution. We hypothesize that the learning curve for a surgeon transferring a program to a second institution is shorter than the initial laparoscopic PD learning curve for the same surgeon. METHODS: A retrospective review of patients who underwent laparoscopic PD for any indication at the first institution (FI) from 2012 to 2017 and the second institution (SI) from 2018 to 2021 was conducted. Standard statistical analysis was performed. The learning curve was identified using one-sided CUSUM analysis of operative times. RESULT: We identified 110 participants, 90 from the FI and 20 from the SI. More patients at the FI were diagnosed with periampullary adenocarcinoma on final pathology compared to the SI (65.6% vs 40.0%, P = .0132). FI operative times stabilized after the 25th laparoscopic PD and SI operative times stabilized after the 5th operation. No statistically significant difference was identified in postoperative complications. CONCLUSIONS: The learning curve and average operative time of an SI laparoscopic PD program was shorter than the initial learning curve for a single surgeon with comparable outcomes. This suggests that complex minimally invasive surgical programs can be safely transferred to another high-volume institution without significant loss of progress.

A comparative analysis of robotic versus open pancreaticoduodenectomy in octogenarians.

Old age is a predictor of increased morbidity following pancreatic operations. This study was undertaken to compare the peri-operative variables between robotic and 'open' pancreaticoduodenectomy, in octogenarians (≥ 80 years of age). Since 2012, with IRB approval, we retrospectively followed 69 patients, who underwent robotic (n = 42) and 'open' (n = 27) pancreaticoduodenectomy. Statistical analysis was performed using chi-square test and Student's t test. Data are presented as median(mean ± SD), and significance accepted with 95% probability. Patients who underwent the robotic approach had a greater Charlson Comorbidity Index [6 (6 ± 1.6) vs 5 (5 ± 1.0), (p = 0.01)] and previous abdominal operations [n = 24 (57%) vs n = 9 (33%), (p = 0.04)]. The robotic approach led to longer operative time [426 (434 ± 95.8) vs 240 (254 ± 71.1) minutes, (p < 0.0001)], decreased blood loss [200 (291 ± 289.2) vs 426 (434 ± 95.8) mL (p = 0.008)], and decreased intraoperative blood transfusions (p < 0.05). Patients who underwent robotic pancreaticoduodenectomy had comparable and at times superior outcomes, consistent with the literature regarding robotic and 'open' pancreaticoduodenectomy. This study indicates that robotic pancreaticoduodenectomy continues to offer same benefits for patients of advanced age and demonstrates age should not be a preclusion to robotic operations.

Pancreatic head resection for carcinoma of the ampulla vateri - better long-term prognosis, but more postoperative complications.

BACKGROUND: Pancreatoduodenectomies are complex surgical procedures with a considerable morbidity and mortality even in high-volume centers. However, postoperative morbidity and long-term oncological outcome are not only affected by the surgical procedure itself, but also by the underlying disease. The aim of our study is an analysis of pancreatoduodenectomies for patients with pancreatic ductal adenocarcinoma (PDAC) and ampullary carcinoma (CAMP) concerning postoperative complications and long-term outcome in a tertiary hospital in Germany. METHODS: The perioperative and oncological outcome of 109 pancreatic head resections performed for carcinoma of the ampulla vateri was compared to the outcome of 518 pancreatic head resections for pancreatic ductal adenocarcinoma over a 20 year-period from January 2002 until December 2021. All operative procedures were performed at the University Hospital Freiburg, Germany. Patient data was analyzed retrospectively, using a prospectively maintained SPSS database. Propensity score matching was performed to adjust for differences in surgical and reconstruction technique. Primary outcome of our study was long-term overall survival, secondary outcomes were postoperative complications and 30-day postoperative mortality. Postoperative complications like pancreatic fistula (POPF), postpancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE) were graded following current international definitions. Survival was estimated using Kaplan Meier curves and log-rank tests. A p-value < 0.05 was considered statistically significant. RESULTS: Operation time was significantly longer in PDAC patients (432 vs. 391 min, p < 0.001). The rate of portal vein resections was significantly higher in PDAC patients (p < 0.001). In CAMP patients, a pancreatogastrostomy as reconstruction technique was performed more frequently compared to PDAC patients (48.6% vs. 29.9%, p < 0.001) and there was a trend towards more laparoscopic surgeries in CAMP patients (p = 0.051). After propensity score matching, we found no difference in DGE B/C and PPH B/C (p = 0.389; p = 0.517), but a significantly higher rate of clinically relevant pancreatic fistula (CR-POPF) in patients with pancreatoduodenectomies due to ampullary carcinoma (30.7% vs. 16.8%, p < 0.001). Long-term survival was significantly better in CAMP patients (42 vs. 24 months, p = 0.003). CONCLUSION: Patients with pancreatoduodenectomies due to ampullary carcinomas showed a better long-term oncological survival, by reason of the better prognosis of this tumor entity. However, these patients often needed a more elaborated postoperative treatment due to the higher rate of clinically relevant pancreatic fistula in this group.
