    Title translation Nezhoubné nádory a pseudotumory v porta hepatis maskující perihilární cholangiokarcinom.
    Abstract Background: Hilar cholangiocarcinoma (HC), also referred to as Altemeier-Klatskins tumour, is a lethal primary extrahepatic carcinoma of biliary epithelial origin, arising within 2cm of the hilar confluence. Radical surgical excision provides the best chance for a cure; however, the management of patients with HC is challenging not only because of the need for a high level of skill in biliary and hepatic resections, but also because of the difficulty in reaching an accurate diagnosis preoperatively. In fact, the differential diagnosis of HC is a diagnostic dilemma which is currently persisting, as modern, sophisticated diagnostic modalities are not always able to provide a definitive preoperative diagnosis. This difficulty is compounded by the fact that alternative entities that mimic HC may be present in up to 25% of patients with hilar obstruction. This makes precise preoperative characterisation of a hilar stricture extremely important by preventing unnecessary, high-risk, major surgical procedures. Therefore, alternative benign entities masquerading as Altemeier-Klatskins tumour deserve an important place in the differential diagnosis of hilar obstruction.
    Purpose: Considering the important clinical implications that a precise diagnosis of the aetiological cause of a biliary obstruction at the liver hilum would have, this paper will focus on the differentiation between HC and benign hilar obstructions and will review benign tumours and pseudotumours masquerading as HC along with their specific diagnostic features.

    Abstract Background: Organ perforation secondary to thermal ablation is a rare but severe complication that can occur in certain patients, in whom tissue dissection and preservation cannot be adequately achieved.
    Case description: A 69-year-old man presented with a gastrocutaneous fistula 20 days after a microwave ablation of liver metastases from colorectal cancer. Besides skin rash, local tenderness, and gastric content discharge from a wound where the probe had been placed, no other signs or symptoms were present. The patient was treated surgically, and a wedge-shaped gastric resection was performed. His postoperative course was uneventful. After 8 months, the patient underwent the same procedure for local progression of the same lesion, using a pulsed MW antenna and a dedicated hydrodissection needle, without complications.
    Conclusions: A gastrocutaneous fistula is a rare complication of microwave ablation. However, adequate hydrodissection can minimize the risk for the development of these complications. Proper treatment of these complications does not preclude repeated usage of microwave ablation in the future.

    Abstract Transposition of inferior vena cava, or, left-sided inferior vena cava (LS-IVC) is a rare clinical entity, in which the inferior vena cava ascends along the left side of the abdominal aorta. Literature contains mainly clinical case reports. Although it is usually not associated with clinical symptomatology, this anomaly should be detected during preoperative planning to avoid iatrogenic injuries intraoperatively. We present a case of left-sided inferior vena cava encountered during laparoscopic lymphadenectomy in a 45-year-old man with previous laparoscopic hemicolectomy due to colon adenocarcinoma. Preoperative CT abdomen revealed the left-sided location of infrarenal IVC and laparoscopic trans-peritoneal aortic lymphadenectomy was decided. Intraoperatively, transposition of inferior vena cava was confirmed in accordance with the CT findings. Resection of lymph node block was conducted with no complications and with minimal blood loss. The postoperative course was uneventful, and the patient was discharged from the hospital the day following surgery. In conclusion, transposition of the inferior vena cava, although rare, constitutes an anatomical variant that should be identified preoperatively to decrease intraoperative risks. Several anatomical variants have been associated with left-sided inferior vena cava.

    Abstract Wound healing is a complex and meticulously orchestrated process involving multiple phases and cellular interactions. This narrative review explores the intricate mechanisms behind wound healing, emphasizing the significance of cellular processes and molecular factors. The phases of wound healing are discussed, focusing on the roles of immune cells, growth factors, and extracellular matrix components. Cellular shape alterations driven by cytoskeletal modulation and the influence of the 'Formin' protein family are highlighted for their impact on wound healing processes. This review delves into the use of absorbable meshes in wound repair, discussing their categories and applications in different surgical scenarios. Interleukins (IL-2 and IL-6), CD31, CD34, platelet rich plasma (PRP), and adipose tissue-derived mesenchymal stem cells (ADSCs) are discussed in their respective roles in wound healing. The interactions between these factors and their potential synergies with absorbable meshes are explored, shedding light on how these combinations might enhance the healing process. Recent advances and challenges in the field are also presented, including insights into mesh integration, biocompatibility, infection prevention, and postoperative complications. This review underscores the importance of patient-specific factors and surgical techniques in optimizing mesh placement and healing outcomes. As wound healing remains a dynamic field, this narrative review provides a comprehensive overview of the current understanding and potential avenues for future research and clinical applications.

    Abstract Purpose: To identify and sum all available evidence pertaining to the management of Amyand's hernia (AH).
    Methods: A systematic search of the MedLine, Scopus, and Google Scholar databases was performed for studies published until January 2020.
    Results: In total, 111 studies incorporating 161 patients were identified, 96 (86.4%) being case reports, 11 (9.9%) case series, and 4 (3.7%) retrospective patient cohorts. Mean patient age was 58.5 ± 19.6 years with 136 (83.9%) being males and 25 (16.1%) females. Furthermore, 149 (92.5%) cases were right-sided hernias while 12 (7.5%) cases were left-sided. Overall, 62.3% of patients presented emergently and 77.3% of patients' cohort were eventually diagnosed with incarcerated AH. Preoperative diagnosis of AH was established in 23.1% of patients and was achieved either by ultrasound (25%) or CT scan (75%). Operative findings consisted of normal appendix in 73 (45.4%) cases, uncomplicated appendicitis in 62 (38.5%) patients, and perforated appendix in 26 (16.1%). Regarding patients with appendicitis, mesh placement was reported for 17 (21.2%), herniorrhaphy was performed for 51 (63.7%) while 12 (15.1%) patients did not undergo hernia repair during the initial operation. Mesh utilization rates were significantly higher in patients with a normal appendix. Seven cases involved AH containing appendiceal neoplasms. Thirteen cases (8.6%) of postoperative complications were documented and a single case of postoperative death.
    Conclusion: AH is a rare type of inguinal hernia usually complicated by appendicitis. Hernia reconstruction should be tailored to each patient individually according to the extent of inguinal canal inflammation.

    Abstract We present a case of a 44-year-old male with chronic hepatitis B that visited the Emergency Department due to epigastric pain after a liver biopsy. The ultrasonography revealed signs of bleeding in the bile ducts. and angiography visualized an arterioportal fistula. Selective right hepatic artery branch embolization was performed, and the bleeding was controlled. Although, the clinical picture was initially improved, the patient presented later with acute abdomen, obstructive jaundice and fever. The patient underwent cholecystectomy with bile duct exploration and placement of a Kehr's T tube in the common bile duct. The postoperative course was uneventful. We also review the relevant literature concerning arterioportal fistula manifested as hemobilia as well as acute cholecystitis occurring after hemobilia.

    Abstract An aberrant muscular fascicle, the so-called "accessory cleido-occipital muscle", originated from the anterior border of the cleido-occipital portion of the right trapezius muscle, was detected during a routine dissection of a female cadaver. The aforementioned muscular bundle coursing in the posterior cervical triangle, almost parallel to the anterior border of the trapezius muscle, inserted ultimately to the clavicle's medial third. In addition, prior to its insertion, the muscle provided a fibrous arch attached to the midportion of clavicle, overlying the main trunk of supraclavicular nerves. We noted that during abduction of the right arm, the fibrous arch entrapped the supraclavicular nerve trunk, presumably leading to sensory disturbances in nerve's area distribution. We review the relative restricted data in the available literature concerning that muscular variant and elucidate its importance during differential diagnosis of a mass and surgical exploration of the posterior cervical triangle.
