Laparoscopic liver resection has become a standard practice in many surgical wards in elective liver surgery, due to its positive impact on reducing hospital stay and postoperative complications, including lower blood loss and transfusion rate. However, achieving proper hemostasis in liver...

Background: The need for safe and efficient dissemination of minimally invasive approach in liver surgery is among the current challenges for hepatobiliary surgeons. After the stage of innovators and pioneers, the following countries should adopt a laparoscopic approach. The aim of this study was to assess the national experience and trend in implementing laparoscopic liver resection (LLR) in Poland. Materials and methods: A national registry of LLR performed in Poland was established in June 2020. All LLR cases performed before were included retrospectively, followed by prospectively collected new cases. Baseline characteristics, preoperative and intraoperative data, short-term results and long-term follow-up were recorded. Results: Since 2010 up to the end of 2022 there were 718 LLRs performed in Poland. The national rate of laparoscopic approach has gradually increased since 2017 (P<0.001), reaching the rate of 11.7% in 2022. There were 443 (61.7%), 107 (14.9%), and 168 (23.4%) LLRs performed in accordance to increasing grades of difficulty. The move towards more demanding cases had an increasing trend over the years (P<0.001). Total intraoperative adverse event and postoperative severe complications rates were estimated for 13.5% (n=97) and 6.7% (n=48), respectively. 30-day reoperation, readmission and postoperative mortality rates were 3.6% (n=26), 2.8% (n=20), and 0.8% (n=6), respectively. While the R0 resection margin was assessed in 643 (89.6%) cases, the total textbook outcomes (TO) were achieved in 525 (74.5%) cases. Overcoming the learning curve of 60 LLRs, resulted in an increasing TO rate from 72.3 to 80.6% (P=0.024). Conclusions: It is the first national analysis of a laparoscopic approach in liver surgery in Poland. An increasing trend of minimizing invasiveness in liver resection has been observed. Responsible selection of cases in accordance with difficulty may provide results within global benchmark values and textbook outcomes already during the learning curve.

Loop ileostomy is commonly performed by colorectal and general surgeons to protect newly created large bowel anastomoses. The optimal timing for ileostomy closure remains debatable. Defining the timing associated with the best postoperative outcomes can significantly improve the clinical results for patients undergoing ileostomy closure. The LILEO study was a prospective multicenter cohort study conducted in Poland from October 2022 to December 2023. Full data analysis involved 159 patients from 19 surgical centers. Patients were categorized based on the timing of ileostomy reversal: early (6 months). Data on demographics, clinical characteristics, and perioperative outcomes were analyzed for each group separately and compared. No significant differences were observed in length of hospital stay (p = 0.22), overall postoperative complications (p = 0.43), or 30-day reoperation rates (p = 0.28) across the three groups. Additional analysis of Clavien–Dindo complication grades was performed and did not show significant differences in complication severity (p = 0.95), indicating that the timing of ileostomy closure does not significantly impact perioperative complications or hospital stay. Decisions on ileostomy reversal timing should be personalized and should consider individual clinical factors, including the type of adjuvant oncological treatment and the preventive measures performed for common postoperative complications.

Summary Drug interactions are a growing problem in the practice of otolaryngology. The use of drugs in patients treated with polypharmacy generates the risk of adverse drug interactions which requires specialized knowledge and active prevention. The most common interactions encountered by ENT physicians are identified on the basis of the analysis of medical order sheets and discussed in the article.

Background and Objectives: The growing number of colorectal cancer patients has highlighted the importance of surgical education in colorectal surgery. Despite the negative impact of the COVID-19 pandemic on surgical training, recent changes in the Polish surgical training program have increased the number of intestinal procedures required to be completed by residents. This study aims to assess the safety of ileostomy reversal procedures performed by surgical residents. Materials and Methods: A multicenter prospective cohort study, the LILEO study, was conducted from October 2022 until December 2023 across 20 Polish surgical departments. The study included 199 patients who underwent ileostomy reversal and were divided into two groups: 139 patients operated by specialist surgeons and 60 patients operated by surgical residents. The primary outcomes measured were postoperative complications, length of hospital stay (LOS), and 30-day reoperation rate. Secondary outcomes included the severity of perioperative complications assessed using the Clavien–Dindo classification and a focused analysis of loop ileostomy reversal outcomes. Results: The median LOS was significantly shorter in the resident group (5.5 days vs. 6 days, p < 0.05). Although the overall complication rate was lower in the resident group (21.7% vs. 33.1% in the specialist surgeon group), this difference was not statistically significant (p = 0.105). The 30-day reoperation rate was 3.3% in the resident group and 8.6% in the specialist surgeon group (p = 0.179). In terms of severity, minor complications (Clavien–Dindo grades 1 and 2) were more common in the specialist group (p < 0.05). The analysis of loop ileostomy reversals revealed no significant differences in postoperative outcomes between the two groups. Conclusions: Ileostomy reversal procedures performed by surgical residents under supervision are safe and feasible, with outcomes comparable to those performed only by specialist surgeons. These findings support ileostomy reversal as a valuable procedure for developing surgical residents’ skills and do not negatively affect postoperative outcomes.

Purpose Laparoscopic liver resection (LLR), being an established method, strongly relies on preoperative and intraoperative imaging. The aim of this study is to assess the utility, with a primary focus on oncological radicality, of intraoperative laparoscopic ultrasonography (IOUS) in nonanatomical laparoscopic liver resections data based on National Polish Registry of Minimally Invasive Liver Surgery. Methods An observational multicenter cohort study involving data from 8 Polish liver surgery departments was conducted. Patients who underwent minimally invasive nonanatomical liver resection in the years 2010–2024 in Poland were included in the research. Patients were divided into a control group without intraoperative ultrasonography and a study group with IOUS. Statistical analysis was performed to assess the perioperative results of IOUS usage in LLR. Results Study results show that IOUS is associated with a considerably higher R0 resection margin (91,6% vs. 84,2%, p = 0,039) with, yet not statistically significant, but higher textbook outcome (82,8% vs. 78,2%, p = 0,258). Other results, such as intraoperative blood loss (median 200 ml vs. 150 ml, p = 0,62 and transfusion rate (9,3% vs. 9,7%, p = 0,896), as well as postoperative complications (11,2% vs. 11,6%, p = 0,175) were similar in both groups. IOUS is associated with longer operation time (median 200 min. vs. 140 min., p < 0,001), however, it is chosen by liver surgeons in more difficult cases (28,4% vs. 15,2% posterosuperior segments, p = 0,003). Conclusion Laparoscopic intraoperative ultrasonography is a useful tool in non-anatomical liver surgery, that ensures oncologic radicality with similar other outcomes compared to no IOUS usage. Therefore, it should be considered as mandatory in LLR. Furthermore, IOUS training programmes should be weighed into being a part of LLR training programmes.
