Introduction: The Buschke–Löwenstein tumor (BLT) is an uncommon sexually transmitted ailment attributed to the human papillomavirus (HPV)—usually the 6 or 11 type (90%)—with male predominance and an overall infection rate of 0.1%. BLT or giant condyloma acuminatum is recognized as a tumor with localized aggressiveness, displaying distinctive features: the potential for destructive growth, benign histology, a rate of 56% malignant transformation, and a high rate of recurrence after surgical excision. There are several treatment choices which have been tried, including laser, cryotherapy, radiotherapy, electrocoagulation, immunotherapy, imiquimode, sincatechins, intralesional injection of 5-fluoruracil (5-FU), isolated perfusion, and local or systemic chemotherapy. In the case of an extensive tumor, preoperative chemotherapy or radiotherapy is used for tumor shrinkage, making the debulking procedure safer. HPV vaccines significantly decrease the incidence of genital warts, also decreasing the risk of BLT; HPV-6 and HPV-11 are included in these vaccines. Materials and methods: We present a 53-year-old heterosexual man, hospitalized in our department in June 2021 with a typical cauliflower-like tumor mass involving the perianal region, which progressively increased in size for almost 7 years. The perianal mass was completely removed, ensuring negative surgical margins. The large perianal skin defect which occurred was reconstructed with fascio-cutaneous V-Y advancement flap. There was no need for protective stoma. The literature review extended from January 1980 and December 2022, utilizing Pubmed and Google Scholar as search platforms. Results: Due to the disease’s proximity to the anal verge and the limited number of reported cases, arriving at a definitive and satisfactory treatment strategy becomes challenging. The optimal approach entails thorough surgical removal of the lesion, ensuring well-defined surgical margins and performing a wide excision to minimize the likelihood of recurrence. In order to repair the large wound defects, various rotation or advancement flaps can be used, resulting in reduced recovery time and a diminished likelihood of anal stricture or other complications. Our objective is to emphasize the significance of surgical excision in addressing BLT through the presentation of a case involving a substantial perianal condyloma acuminatum, managed successfully with complete surgical removal and the utilization of a V-Y advancement flap technique. In the present case, after 5 months post operation, the patient came back with a buttock abscess, which was incised and drained. After another 5 months, the patient returned for difficult defecation, with an anal stenosis being diagnosed. An anal dilatation and sphincterotomy were carried out, with good postoperative results. Conclusions: The surgical management of Buschke–Löwenstein tumors needs a multidisciplinary team with specialized expertise. The reconstruction techniques involved can be challenging and may introduce additional complications. We consider aggressive surgery, which incorporates reconstructive procedures, as the standard treatment for Buschke–Löwenstein tumors. This approach aims to achieve optimal surgical outcomes and prevent any recurrence.

Introduction: Epidermolysis bullosa (EB) represents a group of rare disorders, genetically determined, characterized by skin fragility, blister formation and erosions due to minimal trauma. Depending on the ultrastructural level of skin cleavage, above or below the basement membrane, epidermolysis bullosa can be classified into four major types: simplex, junctional, dystrophic and Kindler Syndrome. In the junctional form of EB, the cleavage level is at the dermo-epidermal junction and the targeted proteins are laminin, type XVII collagen and integrins. The dystrophic form of EB is characterized by cleavage in the dermal layer, collagen VII being the targeted protein. In Kindler EB, multiple levels of cleavage have been described. The mutated gene is FERMT1. Another classification of this disease refers to phenotypic aspects such as extracutaneous lesions, severity, and distribution. The management of epidermolysis bullosa includes supportive wound treatments as well as nutritional support. Case report: We present a case of epidermolysis bullosa presented at birth, in a newborn with no family history of bullous skin conditions. The clinical presentation revealed extensive denuded areas and significant skin fragility as well as mucous and nail involvement. Prenatal diagnosis is very hard to achieve due to increased genetic heterogeneity of the disease. The short-term results were good. The importance of prenatal testing and possibilities of diagnosis are reviewed in this article. Conclusions: EB is a devastating disease. The presented case had a favorable evolution, with good short-term results. Significant morbidity can result from secondary infections of blisters and complications of the extracutaneous manifestations.

Generalized secondary peritonitis is a life-threatening intra-abdominal infection requiring urgent surgical intervention. Despite advances in surgical and antimicrobial therapy, morbidity and mortality remain high. Identifying key prognostic factors is crucial for improving patient outcomes. This review examines significant prognostic indicators and explores the potential role of scoring systems and artificial intelligence in risk stratification. A review was conducted using PubMed, Web of Science, Scopus, and Medline databases. Studies published from 2000 to 2024 focusing on prognostic factors in secondary peritonitis were included. A total of 145 studies were identified, with 40 selected based on relevance and methodological quality. Data extraction included patient demographics, comorbidities, severity scores, microbiological profiles, and artificial intelligence applications in peritonitis management. Poor prognosis was associated with advanced age, severe sepsis, organ failure, chronic kidney disease, cardiovascular comorbidities, and diabetes mellitus. The Mannheim Peritonitis Index (MPI) remains a widely validated prognostic tool, while APACHE II and SOFA scores also provide valuable risk estimates. Increasing multidrug-resistant infections further complicate management and impact outcomes. Emerging evidence suggests that machine learning algorithms may improve early risk stratification and individualized outcome prediction when integrated with conventional scoring systems. Identifying prognostic factors remains essential for optimizing outcomes in secondary peritonitis, and future research should prioritize the clinical validation and integration of AI-based models into perioperative management protocols.

Introduction: Acute secondary peritonitis is a common clinical condition encountered in emergency hospital units, affecting a wide range of patients. The mortality rate for these patients is high and increases with the onset of sepsis, while the risk factors associated with poor outcomes remain under debate. The aim of this study was to analyze the prognostic factors that increase morbidity and mortality in generalized secondary peritonitis. Generalized secondary peritonitis accounts for approximately 1% of emergency hospital admissions. Mortality in generalized secondary peritonitis remains high, ranging from 6% to as much as 55% in cases of severe sepsis, according to various studies. Materials and methods: This study was conducted by searching publications listed on the most prominent search engines and identifying the most relevant articles from our perspective, with a focus on prioritizing studies from recent years. Results/Discussion: Multiple prognostic factors were identified in the studied articles, including age, the presence of associated conditions (cardiovascular, renal, hepatic, neurological, metabolic, oncological), preoperative time, type of peritonitis, septic shock, or severe sepsis. Conclusions: The most consistent prognostic factors increasing morbidity and mortality were advanced age, cardiovascular diseases, chronic renal failure, cancer, and sepsis. Scoring systems greatly assist us in daily practice, and the simpler they are, the more practical they become. Artificial intelligence is making its way into all fields, promising to revolutionize the monitoring of patients with peritonitis.

Background: Minimally invasive surgery has become the standard of care in colorectal cancer management, with laparoscopic techniques widely adopted due to their established short-term benefits and comparable oncological outcomes to open surgery. More recently, robotic-assisted surgery has emerged as an advanced minimally invasive alternative, offering enhanced visualization, improved instrument dexterity, and superior ergonomics. However, the extent to which these technical advantages translate into clinically meaningful improvements remains a subject of ongoing debate. Methods: A systematic review of the literature was conducted using PubMed, Scopus, and Web of Science databases, including studies published between 2005 and 2025. Eligible studies comprised randomized controlled trials, observational studies, cohort studies, and meta-analyses comparing laparoscopic and robotic colectomy for colon cancer. Outcomes of interest included intraoperative parameters (operative time, blood loss, conversion rate), postoperative outcomes (length of hospital stay, complications, mortality), and oncological endpoints (lymph node yield, resection margins, survival). The review was performed in accordance with PRISMA 2020 guidelines. Results: A total of 150 studies met the inclusion criteria. Robotic colectomy was consistently associated with reduced intraoperative blood loss, lower conversion rates to open surgery, and shorter length of hospital stay, albeit at the expense of longer operative times, particularly during the learning phase. Oncological outcomes, including lymph node harvest and margin status, were comparable between approaches, with some studies reporting a modest increase in lymph node yield in robotic procedures. The adoption of intracorporeal anastomosis was significantly higher in robotic surgery, contributing to improved postoperative recovery and reduced wound-related complications. Composite quality metrics, such as textbook outcome (TO), were more frequently achieved in robotic cohorts, largely driven by shorter hospitalization and lower complication rates. However, evidence from randomized controlled trials remains limited, and heterogeneity among studies persists. Conclusions: Robotic colectomy and rectal resection represent a safe and effective alternative to laparoscopic surgery in the treatment of colon cancer, offering potential advantages in perioperative outcomes and surgical precision. Its benefits appear particularly relevant in technically demanding cases, such as deep pelvic dissection and obese patients. Nevertheless, higher costs, longer operative times during the initial learning curve, and limited high-quality randomized evidence warrant cautious adoption. Future large-scale randomized studies are needed to clarify long-term oncological outcomes, cost-effectiveness, and the optimal integration of robotic platforms into standard colorectal surgical practice.
