Introduction: Minimally invasive esophagectomy is associated with lower postoperative morbidity and better quality of life compared to open esophagectomy in patients with comparable oncological outcomes. Robotic-assisted surgery represents the next step in the development of mini- mally invasive surgery. We aim to present the results of a pilot cohort of patients undergoing robotic-assisted minimally invasive esophagectomy (RAMIE).

Methods: An initial cohort of patients with RAMIE was retrospectively analyzed. Operative characteristics, histopathological results, postoperative course, incidence of complications, and postoperative mortality were evaluated.

Results: From 3/2022 to 6/2023, a total of 31 patients underwent RAMIE at our institution, including hybrid RAMIE (robotic abdomen, open chest) in 11 and total RAMIE in 20 patients. Most patients were male, had locally advanced tumors, predominantly adenocarcinoma and neoadjuvant treat- ment. Thirty patients had Ivor-Lewis and one patient had McKeown esophagectomy. The median total operative time was 495 minutes and median blood loss was 200 mL. R0 resection was achieved in 87% of patients. A median of 26 lymph nodes were removed. Postoperative Clavien-Dindo ≥3 complications occurred in 9 (29%) patients. Four (13%) patients required reoperation. Anastomotic leak was found in 5 (16%) and pneumonia in 9 (29%) patients. The median hospital stay was 9 days. One patient died in the postoperative period. Thirty-day and 90-day mortality rates were 0% and 3.2%, respectively.

Conclusion: Our initial experience shows that RAMIE is a safe surgical procedure and we consider its implementation at our institution to be success- ful. After overcoming the learning curve, we hope to reduce the operative time and increase the medical benefit for the patient.

Replacing an infected vascular prosthetic conduit with an allograft is a possible solution of this complication given the low recurrence of infection. It is most commonly utilized for cases where the use of autologous tissue is not an option. We present the case of a 70-year-old patient who had undergone repeated vascular reconstructions in the right lower limb. He was admitted to our department due to a progressively growing mass in the right groin and subsequently placed on the waiting list for a fresh allograft. The patient had the infected false aneurysm and prosthetic material of the femoral bifurcation replaced with an arterial allograft. The previous femoral popliteal autovenous bypass graft was reimplanted into the allograft. There were signs of sepsis during the operation; however, the blood culture was negative. Cultures from neither the wound nor the drain revealed the presence of any bacteria. The patient was discharged on the seventh post-operative day with prophylactic antibiotics. An early followup confirmed that there were no signs of recurrent infection and that the reconstruction remained patent. Seven and half months after the surgery, the femoral popliteal bypass graft became occluded and a conservative approach was chosen. A small thrombosed false aneurysm of the graft was revealed two years after the surgery due to transient non-compliance of the patient to immunosuppression therapy. It was treated conservatively. Two and a half years after the surgery, the allograft still remains open and the limb is preserved.

Introduction: Currently, bariatric surgery is the most effective treatment for the morbid obesity. It provides sustained weight loss as well as demonstrated positive effects on obesity-related comorbidities. The number of procedures performed worldwide has seen a sharp increase in the past twenty years. Therefore, an effort has been developed to establish a consensus in perioperative care based on best evidence.

Methods: The working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology prepared clinical practice guidelines for the ERAS (enhanced recovery after surgery) concept in perioperative care in bariatric surgery. The working group based its guidelines on ERAS guidelines published in 2021. The working group adopted the original text and then adapted the text and added its comments to specific items as appropriate. Electronic voting of all members of the working group was the final phase, by which the strength of consensus was expressed with respect to individual elements of the guidelines.

Results: The Czech working group reached a consensus with ERABS (enhanced recovery after bariatric surgery) guidelines for most elements. The quality of evidence is low for some interventions of the ERAS protocol for bariatric surgery. Therefore, extrapolation from other surgeries and fields is needed for evidence-based practice.

Conclusion: The guidelines are intended for clinical practice in bariatric surgery with the ERAS protocol based on updated evidence and guidelines. It is based on recent and comprehensive ERAS guidelines adopted and adapted by the Czech working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology. Some supplementations and specifications are reflected in comments added to the Czech version.

Circulating tumour cells (CTCs) are tumour cells identified in the peripheral blood of patients with malignant disease. CTCs present a very interesting biomarker with promising potential for use in the treatment management of patients with colorectal cancer. Unlike other tumour biomarkers, CTCs are living tumour cells that carry molecular and biological information about the tumour as a whole and reflect ongoing mutational changes. Detection of CTCs from peripheral blood presents a simple and easily repeatable method of liquid biopsy. However, various techniques of CTC selection and detection render clinical use of CTC as a clinical biomarker difficult. The presence/amount of CTCs correlates very well with prognosis and patients ́ survival. Since CTCs have metastatic potential, knowledge of the effect of different treatment modalities on the amount of CTCs in the blood appears to be very important. It can be expected that a more effective treatment regimen will be associated with a reduction in blood CTC levels, and also with a better prognosis. Conversely, an increase or persistence of CTC levels will be associated with resistance to the applied treatment. Routine use of CTCs in clinical practice is limited predominantly by price and very high variability of available scientific evidence. Recently published studies demonstrated the promising potential of CTCs; however, further research will be required for their routine use in clinical practice.

The most common indication for surgical treatment of parathyroid gland pathology is primary hyperparathyroidism where extirpation of the pathologically changed parathyroid gland is the first-choice treatment. Embryonic development of the lower pair of parathyroid glands is quite complex and is closely related to the tissue of the thymus; for this reason it is not uncommon for a parathyroid adenoma to be located in the mediastinum or directly in the tissue of the thymus. The treatment of primary hyperparathyroidism is becoming a multidisciplinary issue in which radiodiagnostics and nuclear medicine methods play a significant role as they are needed to accurately localize the affected gland and to plan an adequate surgery. In case of intrathoracic localization of parathyroid adenoma, the therapy belongs in the hands of thoracic surgery. At our department, the endocrine surgery program, including parathyroid gland surgery, has a long tradition, and complicated patients are concentrated here, often patients with refractory hyperparathyroidism after a previous procedure. In the last 10 years, almost 2,300 procedures for parathyroid pathology have been performed at the IIIrd Department of Surgery of the 1st Faculty of Medicine, Charles University and University Hospital in Motol, of which some pathologies with mediastinal localization were managed using minimally invasive methods, i.e. videothoracoscopy or robotic-assisted surgery.

Bosworth fracture (BF) is a rare, but a severe injury to the ankle, characterized by displacement of a fragment of the fractured fibula (mostly of Weber B type) from the tibiofibular incisure to the posterior surface of the distal tibia. In 70% of cases, it is associated with a fracture of the posterior malleolus. This injury is not quite well known, with only 175 cases described in the literature to date. BF requires CT examination, including 3D reconstructions. Closed reduction almost always fails as there is an increased risk of compartment syndrome, mainly after repeated attempts at closed reduction. Therefore, operative treatment is indicated as a standard. The outcome of the operation should be always checked by postoperative CT examination.

Introduction: The ureter is present in surgical field during inguinal hernia repair in 0.5-4% of cases. It typically occurs in obese patients, in men and patients after kidney transplants. Right-sided and indirect location of ureteral herniation prevails. The clinical picture is mostly asymptomatic, but possible manifestations include increased frequency of urination with urgency, nocturia, recurrent pyelonephritis, urosepsis, feeling of incomplete emptying of the bladder, signs of GIT obstruction. Diagnostic methods include retrograde pyelography or CT urography. Surgical treatment is indicated in every case of ureteral herniation. Reposition of the ureter retroperitoneally and standard plasty of the inguinal canal is the method of choice.

Methods: 33 cases of ureteral hernia were reviewed in order to write a systematized review of the topic. The case report describes a 68-year-old patient with prostatic hyperplasia and dysuria treated at our institution. A preoperative CT examination with intravenous contrast showed herniation of the right ureter into the inguinal area with hydronephrosis of 2nd degree. Preoperative insertion of a mono-J stent into the right ureter and reposition of the ureter retroperitoneally followed by hernia repair using alloplastic material was performed. There were no postoperative complications.

Results and conclusion: In risky cases, the surgeon should assume the possible presence of a ureter in the inguinal region. Careful dissection in the inguinal area reduces the risk of iatrogenic damage to the ureter.

Introduction: Anal fistula is a common disease with incidence of 5.6 per 100,000 women and 12.3 men. It is most often of cryptoglandular origin. The aim of this study is to evaluate our experience with patients treated for complex anal fistula with our own complex surgical procedure with advancement endorectal flap.

Methods: 524 patients with complex anal fistulas who were sent to our surgical clinic from January 2005 to the end of December 2022 were in- cluded in the study. We established the diagnosis by detecting the fistula tract by physical examination, anoscopy, probing the fistula tract and endorectal ultrasonography. We performed a complex operation together with the construction of the advancement endorectal flap in our own modification for all patients.

Results: Primary surgical intervention in a group of 326 patients with complex anal fistulas (excluding patients with Crohn's disease) was successful in 283 (87%) patients. We identified advancement endorectal flap defect in the postoperative period in 17 (5.2%) patients, soiling in 16 (4.9%) and flatus incontinence in 9 (2.7%) patients. In a group of 120 patients after multiple surgeries (excluding patients with Crohn's disease), our surgical procedure was successful in 92 (76.6%) patients. In the postoperative period, we identified a advancement endorectal flap defect in 6 (5%) patients, soiling in 8 (6.6%) and flatus incontinence in 3 (2.5%) patients.

Conclusions: The construction of the advacement endorectal flap was curative and without affecting the level of anal continence in 87% of patients after primary surgical intervention and in 76.6% after multiple surgical procedures. Complex surgery with the construction of the advancement endorectal flap according to our procedure preserves the function of the sphincters and has a relatively low percentage of recurrences. The number of previous surgical interventions had no affect on the level of anal continence.

Lung transplantation has become a standardized and widely accepted treatment modality for selected end-stage lung diseases. Many factors influ- ence the long-term survival of patients after lung transplantation. One of the most important is clearly the development of chronic lung allograft dysfunction (CLAD). This review summarizes current knowledge of the histopathology of CLAD and its clinical characteristics. It also describes lung re-transplantation as the only causal therapy, its possible complications, and outcomes in standard and high-urgency patients awaiting a suitable organ with extracorporeal membrane oxygenation support. Fundoplication is an important surgical modality potentially leading to an improvement of the patients' condition. The indications and outcomes of this surgical procedure are discussed in a separate chapter. In addition, several nonsurgical treatment options aimed at slowing the progression of CLAD are outlined, as well as ongoing research focused on extending the life of these patients.

The article reviews the history of inguinal hernia surgery. At various times, different procedures and diverse materials were used for hernia repair. However, the effectiveness and safety of inguinal hernia repair emerged only after the anatomic features of the inguinal region had been elucidated in a monograph by Henri Fruchaud "Anatomie des hernies de l'aine" published in 1956. The Italian surgeon Edoardo Bassini began a new era in herniology. For a longtime, his classic procedure with its modifications was the most popular in surgical practice. In 1959, Lloyd M. Nyhus proposed inguinal hernia repair according to the concept of the pre-abdominal (posterior) approach that later became the basis for developing the transabdominal preperitoneal hernia repair (TAPP). In 1992, M. Arregui performed the first ТАРР using a prolene mesh. In 1986, Irving Lichtenstein proposed the concept of "tension-free repair". Basing on his concept, Lichtenstein described an open technique of inguinal hernia repair, which now bears his name and is popular in surgical practice. In 1993, the term "extraperitoneal hernia repair" first appeared in an article by Edward H. Phillips. However, J. Dulucq developed the modern ТЕР technique. Currently, three tension-free inguinal hernia repairs (TAPP, ТЕР and Lichtenstein procedure) and one tension inguinal hernia repair (Shouldice procedure) dominate in inguinal hernia surgery.
