According to current revised Fukuoka guidelines, there is an indication for resection of BD-IPMN of the pancreas with "worrisome features", as there is a risk of malignant degeneration of up to 30%. This can be performed as a non-anatomical local excision in the absence of clinical, radiological and laboratory signs of malignancy.Robotic enucleation for benign tumours of the pancreas is a very good alternative to resecting procedures, especially those using open techniques. This surgical treatment option is recommended by the "International consensus statement on robotic pancreatic surgery" in a case of a minimum distance to the main pancreatic duct of at least 2 mm.In addition to the known advantages of minimally invasive surgery, this parenchyma-sparing approach results in preservation of endo- and exocrine function (ca. 90%) and 10-year progression-free survival of ca. 75% with slightly increased morbidity (ca. 60%) compared with resecting procedures.The following video article presents the surgical video of a robotic cyst enucleation (for suspected BD-IPMN with "worrisome features") in the pancreatic head and uncinate process in a 62-year-old female patient with special emphasis on the most important vascular landmarks, special features of the approach and advantages of the robotic technique., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: In recent years, there have been changes in the treatment of ductal pancreatic carcinoma with regard to multimodal therapy and also surgical therapy. These changes have not yet been explored in large nationwide studies in Germany. The present work gives an initial overview from a surgical perspective of the developments in diagnosis, therapy and survival of pancreatic cancer within the last 19 years in Germany., Methods: In this cohort of 18 clinical cancer registries in Germany, patients with a diagnosis of ductal pancreatic cancer from 2000-2018 were included. The patients were categorised according to the years of diagnosis (2000-2009 vs. 2010-2018) and treatment modalities and compared., Results: In the cohort of approx. 48000 patients with ductal pancreatic cancer, the number of newly diagnosed cases increased from approx. 18000 to 30000 patients in the two ten-year periods. The median overall survival increased slightly but statistically significantly from 7.1 to 7.9 months (p < 0.001). The resection rate increased from 25% to 32%, with the proportion of patients for whom no specific therapy was reported decreased by 11%. The rate of palliative chemotherapy and neoadjuvant chemotherapy also increased from 16% to 20% of the patients and from less than 1% to 2% of the patients, respectively. The median survival in the curatively treated subgroups was up to 24 months., Summary: The cancer registry data appear to confirm the known increase in the incidence of pancreatic cancer in the western world. Resection rates and the rates of treatment with neoadjuvant and palliative intent also increased. The overall survival of all patients with ductal pancreatic cancer only increased marginally. In the subgroups of patients who were treated with curative intent, however, significantly longer survival times were found., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

In the surgical treatment of gastroesophageal reflux disease and of hiatal hernias, the high rate of recurrence of hiatal hernias is a central problem. Against this background, various, primarily alloplastic, meshes are used to augment suture closure on the esophageal hiatus. Very different results have been reported in the past and the use of meshes in hiatus reconstruction is controversial. In addition to the frequency of recurrences, reports about complications of mesh augmentation are in the foreground. On the basis of several prospective randomised double-blinded comparative studies and meta-analyses (class Ia and Ib evidence), the current data do not show any advantages of mesh-augmented hiatoplasty for the prevention of recurrence of hiatal hernia. At the same time, there exist reports of more long-term postoperative complications, especially dysphagia, after use of meshes for augmentation of hiatus reconstruction. Therefore, routine use of mesh augmentation for hiatus reconstruction is currently not recommended., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The frequency of bariatric operations has increased in Germany. Primary operations are usually performed at specialised centres. However, late complications may develop months or even years after the operation, and every general and visceral surgeon may be confronted with them, regardless of the size and specialisation of their clinics. The laparoscopic Roux-Y gastric bypass is the most frequently performed bariatric operation worldwide. During this procedure, the alimentary loop is lifted up in front of the colon to form a pouch, which creates a mesenteric space, also called the Petersen space, dorsal to the alimentary loop and below the transverse colon. Both here and around the mesenteric space of the Roux anastomosis, an internal hernia may develop, i.e. the small intestine can twist on its own axis. Abdominal discomfort due to intestinal obstruction is unspecific, but very pronounced. Clinically, patients either present with an acute abdomen or with intermittent unspecific abdominal pain with nausea, and rarely also with vomiting. Clinical examinations and lab chemistry tests usually do not reveal any indicative findings. In cases of doubt, therefore, contrast-enhanced computed tomography of the abdomen is the diagnostic imaging procedure of choice. A diagnostic laparoscopy should be performed in every patient with a clinical suspicion of an internal hernia, even if the CT scan is unremarkable. This should be done by a surgeon who is well-versed in laparoscopy and experienced in bariatric surgery, since classification of the intestinal loops is very difficult without knowledge of the hernial orifices. First, an inframesocolic view is obtained with the transverse colon being lifted. From here, the open Petersen space offers a direct view of the ligament of Treitz from the right side. If small intestine is found to the right of the ligament, there is a Petersen hernia. After the inframesocolic view, the gastroenterostomy should be located and the alimentary loop should be followed in distal direction towards the jejunojejunostomy, where the second possible space may be found. Once both spaces have been located and a hernia has been reduced as appropriate, the spaces should be closed with non-absorbable suture., (Georg Thieme Verlag KG Stuttgart · New York.)
