Background: The incidence of pilonidal sinus shows a steadily rising tendency, especially in the patient age group of up to 40 years. Treatment of this condition is often protracted involving lengthy sick leave and an increased risk of recurrence. The optimal treatment of pilonidal sinus remains open to debate, but it should focus on decreasing the length of hospitalization, promoting a rapid return to daily life, maintaining low pain levels, and keeping costs at a minimum.

Materials and methods: In our study conducted between 2017 and 2021, we focused on treatment of pilonidal sinus. We performed 50 elastic ligature procedures with a median observation time of 30 months. The patients were divided into three groups according to the characteristics of pilonidal sinus: (1) acute primary abscess; (2) acute recurrent abscess; and (3) chronic fistula.

Results: Out of a total of 50 patients with a subsequent 30-month follow-up, we observed complete recovery in 47 patients and recurrence in three patients. Return to work was possible immediately after the operation, with an average total treatment time of 1 month for complete healing of the defect.

Conclusion: The current results suggest that the technique of elastic ligature is a desirable solution for pilonidal sinus, because of the initial low costs, no need for hospitalization, and good patient tolerance.

Aim: The aim of this work is to illustrate the diversity of vascular injuries in terms of vascular segments or body regions, accident mechanisms and specific patient constellations.

Method: A representative case collection was compiled based on current and relevant scientific references in PubMed, own clinical experiences, vascular surgical and novel image-guided interventional options.

Results: The diagnostics of vascular injuries in the context of trauma and fractures are based on a thorough physical examination. In addition, the hard and soft signs preferred by the Western Trauma Association should be included in the decision. Doppler ultrasonography examination is the safest and gentlest noninvasive examination procedure for a suspected vascular injury due to repeatable and comparative measurements. The stabilization of a fracture, ideally using an external fixator, should be performed before vascular reconstruction whenever possible, unless massive bleeding, hypovolemic shock or a rapidly spreading hematoma represent an immediate indication for surgery. In pediatric supracondylar fractures, avascular injury without relevant ischemia has frequently been described (pink pulseless hand). In this case, the fracture should first be reduced as the pulse often recovers. Due to the increasing availability, good technical handling and high technical success rate as well as the relatively limited interventional trauma, endovascular treatment of traumatic vascular injuries has become widely accepted. Traumatic aortic ruptures are associated with a high mortality even at the accident site. Rapid endovascular treatment using a stent prosthesis significantly increases the injured person's chances of survival.

Conclusion: Vascular injuries in connection with fractures or multiple injuries require interdisciplinary cooperation between the specialties involved.

At the latest since the Medical Services Healthcare Insurance Reform Act (MDK), the declared will of the legislation is the conversion of operations previously carried out in an inpatient setting to an outpatient setting. In trauma surgery and orthopedics numerous operations are carried out that could principally also be performed in an outpatient setting; however, a prerequisite is a medical assessment of the suitability of patients as well as an economic and normative framework that makes outpatient surgery attractive. Both the Outpatient Surgery in Hospitals Catalogue (AOP-Katalog) and the first edition of the Hybrid Diagnosis-related Groups (DRG) define interventions in trauma surgery that could be carried out in an outpatient setting. Hospitals are therefore required to find solutions for these interventions under processual and economic provisos. These range from omission of outpatient operations to the expansion as a separate financial department in the hospital. With the introduction of the hybrid DRG, the legislation enables equal remuneration for outpatient versus short-term inpatient treatment and leaves the case management up to the hospital; however, the performance of the AOP in the setting of a hospital and also hybrid case flat rates are as a rule not economically viable and bear the risk of the failure of all efforts at conversion to outpatient settings. It is necessary to carry out a fundamental revision of the remuneration and framework conditions for outpatient operations in trauma surgery and orthopedics in hospitals, involving practitioners. This is the only way that the conversion to outpatient treatment can succeed.

Rectovaginal fistulas (RVF) represent less than 5% of anorectal fistulas. The classification of RVF is based on the localization (low vs. high) and the etiology. The most frequent causes of RVF are birth trauma, Crohn's disease, previous surgery and pelvic irradiation. In most cases a clinical diagnostic assessment is sufficient. Additionally, endosonography is a reliable tool to detect sphincter defects. Computed tomography (CT) and magnetic resonance imaging (MRI) are reserved for special situations (e.g., RVF related to anastomotic leakage, after pelvic irradiation or associated with complex perianal fistulizing Crohn's disease). The surgical treatment is primarily oriented to the localization and etiology. Surgical techniques range from local procedures (e.g., endorectal advancement flap repair, transvaginal or transperineal closure) up to more invasive tissue interposition (e.g., bulbocavernosus muscle fat tissue flap or transposition of the gracilis muscle). In "high" RVF transabdominal approaches such as coloanal anastomosis, pull through procedures or omental interposition are indicated. All surgical procedures show high recurrence rates. Several operations are mostly necessary and a stoma creation is often required.

Introduction: Venous aneurysms are a rare entity in vascular surgery, which are mostly described in individual case series and meta-analyses generated from them. The treatment concepts are diverse and surgical treatment is highlighted due to the risk of thrombosis and pulmonary embolism. There is still an ongoing debate regarding the postoperative necessity and duration of anticoagulation.

Method: Case series of a consecutive patient cohort with venous aneurysms from the last 18 years in a center of (highly specialized care) vascular surgery including i) own experiences obtained in daily vascular surgical practice and ii) a selected and current literature search of relevant references on possible and, in particular, established diagnosis-specific therapeutic concepts.

Results: Between 2005 and 2023, a total of 11 cases of venous aneurysms were reported in patients aged 30-84 years (mean: 52.5, median: 50), with 1 patient requiring surgery for a recurrence after 2 years. The gender ratio was 7:3 (m:f) and the popliteal vein was the most frequently affected anatomical region with 36.4%, followed by the internal jugular vein and axillary/subclavian vein each with 18.2%. Aneurysms of the inferior vena cava, the common iliac vein and the cubital vein occurred only once. Surgical treatment of the aneurysms was performed in 9 cases. The surgical methods used were i) tangential resection of the aneurysm wall and continuous purse-string suture, ii) resection of the aneurysm and interposition of an 8‑mm GORE-TEX® vascular graft prosthesis (Gore, Putzbrunn, Germany), iii) ligation of the aneurysm and iv) ligation with subsequent resection of the aneurysm.

Conclusion: The rarity of venous aneurysms should be a reason to register these cases centrally (possibly, nationwide diagnosis-related register). Surgical treatment is usually unproblematic and associated with few complications. The risk of pulmonary embolism appears to be significantly increased in venous aneurysms of the extremities, pelvic veins and inferior vena cava, while venous aneurysms of the head and neck are significantly less prone to this. Perioperative and postoperative anticoagulation has been adapted to the development of specific anticoagulants and novel drugs, in favor of treatment with direct oral anticoagulants (DOAC). In personal experience, immediate postoperative heparin perfusion (low dose) and subsequent therapeutic bridging with low-molecular-weight heparin before switching to an anticoagulant for outpatient clinic-based care appears to safeguard the perioperative phase with respect to keeping the surgery-related complication rate (e.g., thrombosis, bleeding) low.

Pancreatic cystic lesions represent a challenging heterogeneous entity with a potential risk of malignant transformation. The diagnostics include in particular medical history taking with collection of relevant clinical information and high-resolution imaging, preferably using magnetic resonance imaging (MRI) with MR cholangiopancreatography (MRCP) and/or endoscopic ultrasonography. A differentiation between different cystic entities and identification of risk factors are crucial for making appropriate treatment decisions. Only a small proportion of pancreatic cystic neoplasms require surgery. Pancreatic cystic lesions with a relevant risk of malignancy, such as main duct intraductal papillary mucinous neoplasms (IPMN), mucinous cystic neoplasms (MCN), solid pseudopapillary neoplasms (SPN) and general cystic pancreatic lesions with risk factors regardless of the entity, should be resected, whereas an individualized approach is required for branch duct IPMN and serous cystic neoplasms (SCN) and dysontogenetic cysts require no treatment. Parenchyma-sparing and minimally invasive resection techniques should be preferred whenever possible for resecting pancreatic cystic tumors. Approximately 10% of patients develop recurrences over time.
