Early adoption of laparoscopic liver surgery in Poland: a national retrospective cohort study.

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.

Long-term results of simultaneous and delayed liver resections of synchronous colorectal cancer liver metastases.

BACKGROUND: Complete resection is the only potential curative treatment of synchronous colorectal liver metastases. Although simultaneous liver and colon resections became an accepted procedure at specialized centres for selected patients, there is still little data about the long-term results of simultaneous operative procedures compared with those of delayed operations. In this retrospective study, the long-term survival rates of the patients who underwent simultaneous or delayed resections were presented. METHODS: A retrospective analysis of liver resections in our institution between 1997 and 2012 was performed. Among 131 patients presented with synchronous colorectal liver metastases, 52 underwent simultaneous and 79 delayed resection. Patients with extrahepatic metastases were excluded, except for 10 patients with metastases limited to liver and lungs that were qualified as resectable. RESULTS: Age, sex and localization of the primary tumour were similar in the two groups. In the delayed resection group, the majority of colon resections were performed in different hospitals. The frequency of complications did not differ between the groups. The 1, 5 and 10 years survival rates were 77%, 43% and 20% in simultaneous and 86%, 37% and 19% in delayed resection group, respectively. No cancer related deaths occurred after more than 10 years of observation. CONCLUSION: The long-term outcome of simultaneous resection of synchronous colorectal liver metastases is comparable to delayed resection.

The Glubran 2 glue for mesh fixation in Lichtenstein's hernia repair: a double-blind randomized study.

INTRODUCTION: With an average incidence rate of 11%, chronic pain is considered the most serious complication of inguinal hernioplasty after surgical site infection. One of the proposed solutions to this problem is to use tissue adhesive for mesh fixation, which helps prevent nerve and tissue damage. AIM: The goal of this study was to compare mesh fixation with the use of sutures vs. adhesive in Lichtenstein's inguinal hernia repair in a randomized, double-blind one-center study. MATERIAL AND METHODS: The study group consisted of 41 males with primary inguinal hernia undergoing Lichtenstein's repair (20 - adhesive; 21 - suture) and remaining in follow-up from July 2008 to November 2010. Randomization took place during the operation. The follow-up was performed by one surgeon (blinded) according to a pre-agreed schedule; the end-of-study unblinding was performed during the last follow-up visit, usually 16 months postoperatively. RESULTS: In 1 patient from the "adhesive" group, a recurrence was observed one year after the initial repair. The early postoperative pain was less intense in this group. In later postoperative periods the method of mesh fixation had no influence on the pain experienced by the patient. Other complications were not correlated with the method of mesh fixation. CONCLUSIONS: In this randomized, one-center double-blind clinical study of males with primary inguinal hernia it has been show during follow-up that the use of Glubran 2 cyanoacrylate adhesive for mesh implant fixation yields similar recurrence and chronic pain rates as the classical suture technique. In the early postoperative period, the pain reported by these patients was relatively weaker; patients undergoing adhesive mesh fixation experienced a quicker return to daily household activities.

Desarda versus Lichtenstein technique for primary inguinal hernia treatment: 3-year results of a randomized clinical trial.

BACKGROUND: The Shouldice method and other tissue-based techniques are still acknowledged to be acceptable for primary inguinal hernia repair according to the European Hernia Society guidelines. Desarda's technique, presented in 2001, is an original hernia repair method using an undetached strip of external oblique aponeurosis. This randomized trial compared outcomes after hernia repair with Desarda (D) and mesh-based Lichtenstein (L) techniques. METHODS: A total of 208 male patients were randomly assigned to the D or L group (105 vs. 103, respectively). The primary outcomes measured were recurrence and chronic pain. Additionally, early and late complications, foreign body sensation, and return to everyday activity were examined in hospital and at 7, 30 days, and 6, 12, 24, and 36 months after surgery. RESULTS: During the follow-up, two recurrences were observed in each group (p = 1.000). Chronic pain was experienced by 4.8 and 2.9% of patients from groups D and L, respectively (p = 0.464). Foreign body sensation and return to activity were not different between the groups. There was significantly less seroma production in the D group (p = 0.004). CONCLUSIONS: The results of primary inguinal hernia repair with the Desarda and Lichtenstein techniques are comparable at the 3-year follow-up. The technique may potentially increase the number of tissue-based methods available for treating groin hernias.

[Attempted assessment of the incidence and cost of surgical treatment of inginal hernias in Poland in the years 2001-2002]. / Próba oceny czestosci wystepowania i kosztów leczenia operacyjnego przepuklin pachwinowych w Polsce w latach 2001-2002.

A comprehensive, up-to-date assessment of the incidence and treatment cost of inguinal hernias in Poland is made difficult by the lack of a central data registry and insufficient accuracy of the data available. Therefore, research was undertaken in order to evaluate the incidence and cost of inguinal hernia treatment in the years 2001-2002 in Poland. Survey-derived data was collected from Regional Health Funds operating similar data management systems in 2002 and the Regional Branches of the National Health Fund in 2003. The number of inguinal hernia repairs, length of hospital stay, as well as the cost of these procedures and the overall number of insured people in the region were assessed. Data was obtained from 11 units (Regional Health Funds, Branches of the National Health Fund). The length of hospital stay differed between individual Regional Health Funds. The annual cost of inguinal hernia treatment amounts to approximately 100 million PLN.
