Objective: Splenectomy is regularly performed in total and distal pancreatectomy due to technical reasons, lymph node dissection and radicality of the operation. However, the spleen serves as an important organ for competent immune function, and its removal is associated with an increased incidence of cancer and a worse outcome in some cancer entities (Haematologica 99:392-398, 2014; Dis Colon Rectum 51:213-217, 2008; Dis Esophagus 21:334-339, 2008). The impact of splenectomy in pancreatic cancer is not fully resolved (J Am Coll Surg 188:516-521, 1999; J Surg Oncol 119:784-793, 2019)., Methods: We therefore compared the outcome of 193 pancreatic cancer patients who underwent total or distal pancreatectomy with (Sp) or without splenectomy (NoSp) between 2015 and 2021 using the StuDoQ|Pancreas registry of the German Society for General and Visceral Surgery. In addition, we integrated our data into the existing literature in a meta-analysis of studies on splenectomy in pancreatic cancer patients., Results: There was no difference between the Sp and NoSp groups regarding histopathological parameters, number of examined or affected lymph nodes, residual tumor status, or postoperative morbidity and mortality. We observed a significantly prolonged survival in pancreatic cancer patients who underwent total pancreatectomy, when a spleen-preserving operation was performed (median survival: 9.6 vs. 17.3 months, p = 0.03). In this group, splenectomy was identified as an independent risk factor for shorter overall survival [HR (95%CI): 2.38 (1.03 - 6.8)]. In a meta-analysis of the existing literature in combination with our data, we confirmed splenectomy as a risk factor for a shorter overall survival in pancreatic cancer patients undergoing total pancreatectomy, distal pancreatectomy, or pancreatic head resection [HR (95%CI): 1.53 (1.11 - 1.95)]., Conclusion: Here, we report on a strong correlations between removal of the spleen and the survival of pancreatic cancer patients undergoing total pancreatectomy. This should encourage pancreatic surgeons to critically assess the role of splenectomy in total pancreatectomy and give rise to further investigations., Competing Interests: Declarations.

The paradigm shift in the treatment concept for acute appendicitis is currently the subject of intensive discussions. The diagnosis and differentiation of an uncomplicated from a complicated appendicitis as well as the selection of an adequate treatment is very challenging, especially since nonoperative treatment models have been published. The laparoscopic appendectomy is still the standard for most cases. Guidelines for the treatment of acute appendicitis do not exist in Germany. Therefore, a group of experts elaborated 21 recommendations on the treatment of acute appendicitis after 3 meetings. After initial definition of population, intervention, comparison and outcome (PICO) questions, recommendations have been finalized through the Delphi voting system. The results were evaluated according to the current literature. The aim of this initiative was to define a basic support for decision making in the clinical routine for treatment of acute appendicitis.

Objective: To assess the long-term survival and quality of life in total pancreatectomies and to identify risk factors for perioperative morbidity and mortality., Background: Total pancreatectomy may be required in locally advanced or centrally located pancreatic neoplasms to achieve complete tumor clearance, but available data on short- and long-term results are limited., Methods: A total of 434 consecutive total pancreatectomies for primary pancreatic or periampullary tumors were performed between October 2001 and September 2012 at the authors' institution and were prospectively documented and analyzed. Long-term outcome was assessed using Kaplan-Meier and quality of life analysis (EORTC-QLQ-C30 and PAN26). Uni- and multivariate analysis was performed to identify perioperative risk factors and predictors for long-term survival., Results: Extended total pancreatectomies were performed in 54% of cases, with arterial and portal vein resections in 15% and 32%, respectively. Overall 30-day and in-hospital mortality rates were 3.7% and 7.8%, respectively. High blood loss, long operative time, and arterial resections were independently associated with increased perioperative mortality (P ≤ 0.018). In malignant disease, median and 5-year survival were good for standard total pancreatectomies (28.6 months and 24.3%, respectively) and were significantly impaired after vascular resections (P < 0.001). Poor tumor grading, high American Joint Commission on Cancer tumor stage, age more than 70 years, and an R1 resection were independent prognostic parameters. Long-term global quality of life was comparable with a matched healthy control group., Conclusions: Standard total pancreatectomy, if needed, is associated with good long-term outcome in pancreatic cancer. Marked surgical morbidity and impaired survival associated with vascular resections reflect the invasiveness of extended total pancreatectomies and the underlying advanced malignant disease.

Background: Partial pancreatico-duodenectomy (PD) is the standard treatment for tumors of the pancreatic head. Today, preservation of the pylorus has been widely accepted as the surgical standard in this procedure. A common postoperative complication is the occurrence of delayed gastric emptying (DGE), which causes impairment of oral intake andpatients' quality of life, prolongation of hospital stay and delay of further treatment (for example adjuvant chemotherapy). In a small number of two retrospective and one randomized studies, a modification by resection of the pylorus with preservation of the stomach has shown to reduce DGE incidence. The aim of the present study is to investigate the effect of pylorus resection on postoperative DGE in PD., Methods/design: Patients undergoing elective PD for any indication equal or older than 18 years and who have given informed consent will be included. Patients will be randomized to either PD with pylorus preservation or PD with pylorus resection and complete stomach preservation. Sample size (n = 89 patients per group) is calculated on an assumed difference in DGE incidence of 20%. Primary study endpoint is DGE within 30 days; secondary endpoints are operation time, blood loss, morbidity, mortality, hospital stay and quality of life (QoL)., Discussion: DGE is a relevant clinical problem following PD with a great impact on patients' recovery, length of hospital stay, QoL and consecutive adjuvant therapies. As there is no causal therapy, prevention of DGE is essential to improve outcome. The technical modification of pylorus resection may offer a simple and effective method for this purpose. The present study is designed to increase the existing body of evidence and potentially change the future standard surgical procedure of PD., Trial Registration: German Clinical Trials Register DRKS00004191.

Objectives: To investigate the incidence, characteristics, and prognostic impact of prior extrapancreatic malignancies on patients with pancreatic cancer (PDAC)., Methods: Records from 1733 patients who underwent surgery for PDAC were analyzed for the occurrence of prior extrapancreatic malignancies. Patients' records showing extrapancreatic malignancies were then analyzed for tumor type, epidemiological data, risk factors, PDAC tumor stage, and long-term survival., Results: A total of 239 patients with PDAC (13.8%) had a history of 271 extrapancreatic tumors; 26 patients had a history of two pancreatic cancers, and 3 patients had 3 extrapancreatic cancers. The most common extrapancreatic tumors were breast cancer (56 patients) and prostate cancer (41 patients), followed by colorectal, reno/urothelial, and gynecologic tumors (39, 32, and 23 patients, respectively). No significant difference in overall survival was found between patients with PDAC with or without extrapancreatic malignancies., Conclusions: Pancreatic cancer is associated with extrapancreatic malignancies in a remarkable number of patients. A history of extrapancreatic malignancies does not influence prognosis and should not be an obstacle to a curative therapeutic approach. Surveillance of patients with extrapancreatic malignancies, especially breast, prostate, and colorectal cancer, could allow for earlier PDAC diagnosis and therefore improve prognosis of these patients.

Objective: To evaluate the safety and outcome of multivisceral pancreatic resections for primary pancreatic malignancies., Background: Curative resection is the only potential cure for patients with pancreatic cancer, but some patients present with advanced tumors that are not resectable by a standard pancreatic resection. Data on risk and survival analysis of extended pancreatic resections is limited., Methods: One hundred one patients who had a multivisceral pancreatic resection between 10/2001 and 12/2007 were identified from a prospective database, and perioperative and long-term results were compared with those of 202 matched patients with a standard pancreatic resection. Uni- and multivariate regression analysis were performed to identify parameters that are associated with perioperative morbidity. Long-term survival was evaluated., Results: Colon, stomach, adrenal gland, liver, hepatic or celiac artery, kidney, or small intestine were resected in 37.6%, 33.7%, 27.7%, 18.8%, 16.8%, 11.9%, and 6.9% of the 101 patients with multivisceral resection, respectively. Additional portal vein resection was performed in 20.8% of patients. Overall and surgical morbidity but not mortality was significantly increased compared with standard pancreatic resections (55.5% vs. 42.8%, 37.6 vs. 25.3%, and 3.0% vs. 1.5%, respectively). Uni- and multivariate analysis identified a long operative time and the extended multivisceral resection of 2 or more additional organs as independent risk factors for intraabdominal complications or need for relaparotomy. Median survival was comparable to that of standard pancreatic resections., Conclusions: Multivisceral resections can be performed with increased morbidity but comparable mortality and long-term prognosis as compared with standard pancreatic resections at high volume centers. Increased morbidity is related to extended multivisceral resections with a long operative time.

Up to now, in most surgical departments there has been no central patient management coordinating the admission, the diagnostic work-up, and the surgical procedures of patients with the resources available in the hospital. In future, however, it will be essential for surgical departments to establish such a central patient management, not only in view of the importance of patient-oriented medicine but also considering the planned introduction of diagnosis related groups. A central patient management will reduce preoperative and overall length of stay through adequate organisation and communication structures. In addition, a central patient management will make optimal use of the available resources in terms of operation rooms and hospital beds. In this article, we will present our basic concept of a central patient management in a surgical university department.
