    Surgical Repair of Bile Duct Injuries Due to Cholecystectomy—An Experience from a Referral Center in Slovenia

    by Irena Plahuta, Špela Turk, Barbara Lovrenčič Petreski, Tomislav Magdalenić, Stojan Potrč, Arpad Ivanecz

    Background: Bile duct injury (BDI) during (laparoscopic) cholecystectomy has an incidence of up to 1.5%. This retrospective study aimed to report the outcomes of surgical repair of BDI due to these procedures at a tertiary referral center. Methods: A retrospective review of patients’ records was conducted. The BDI’s clinical presentations, Strasberg classification, surgical repairs, and outcomes were reported. Results: From 2003 to 2024, 47 BDIs were identified. In total, 34.0% were recognized intraoperatively. The BDI types included Strasberg types B (2, 4.3%), C (5, 10.6%), D (11, 23.4%), E1 (4, 8.5%), E2 (12, 25.5%), E3 (5, 10.6%), E4 (3, 6.4%), and E5 (5, 10.6%). The T-tube group included 6 (12.8%) patients, the primary repair and T-tube group included 10 (21.3%) patients, and the Biliodigestive anastomosis group included 31 (65.9%) patients. The overall morbidity rate was 40.4%, the major morbidity rate was 21.3%, and the mortality rate was 4.3%. Grade A patency was achieved in 95.6% of patients. In the Biliodigestive anastomosis group, the actuarial 1-, 5- and 10-year grade A patency rates were 77.0%, 70.0%, and 70.0%, respectively. Conclusion: The rate of BDI remains stable. The outcomes of repairs in terms of complications and patency rates are comparable to those in other reports.

    Laparoscopic and Open Distal Pancreatectomy—An Initial Single-Institution Experience with a Propensity Score Matching Analysis

    by Irena Plahuta, Žan Šarenac, Medeja Golob, Špela Turk, Bojan Ilijevec, Tomislav Magdalenić, Stojan Potrč, Arpad Ivanecz

    Laparoscopic distal pancreatectomy is a minimally invasive approach for the surgical treatment of neoplasms in the distal pancreas. This study aimed to compare this approach to the open procedure. A retrospective analysis of a prospectively maintained database of 400 pancreatectomies was performed. The laparoscopic distal pancreatectomy group (LDP) was compared to the open distal pancreatectomy group (ODP). A propensity score matching analysis (PSM) was performed. From 2016 to 2023, 108 distal pancreatectomies were carried out, 19 (17.6%) laparoscopically and 89 (82.4%) openly. The conversion rate was 13.6%. The severe morbidity rates were 28.1% in the ODP group, 47.4% in the LDP group, and 15.8% in the ODP-PSM group. The difference between the latter two was statistically significant (p = 0.034) due to the high rate of Clavien–Dindo grade 3a complications (42.1% versus 10.5%, p = 0.042) in the LDP group. The 90-day mortality rates were 3.3% in the ODP group and 5.3% in the other two groups. The LDP group had a shorter duration of intravenous narcotic analgesia (5 versus 7 days, p = 0.041). There was no difference in the R0 resection or postoperative pancreatic fistula rates. Our attention should be drawn to preventing postoperative complications because the oncological outcomes are already comparable with those of the open procedure, and postoperative pain management is promising.

    Ranking as a Procedure for Selecting a Replacement Variable in the Score Predicting the Survival of Patients Treated with Curative Intent for Colorectal Liver Metastases

    by Irena Plahuta, Matej Mencinger, Iztok Peruš, Tomislav Magdalenić, Špela Turk, Aleks Brumec, Stojan Potrč, Arpad Ivanecz

    Background and Objectives: The issue of a missing variable precludes the external validation of many prognostic models. For example, the Liverpool score predicts the survival of patients undergoing surgical therapy for colorectal liver metastases, but it includes the neutrophil–lymphocyte ratio, which cannot be measured retrospectively. Materials and Methods: We aimed to find the most appropriate replacement for the neutrophil–lymphocyte ratio. Survival analysis was performed on data representing 632 liver resections for colorectal liver metastases from 2000 to 2020. Variables associated with the Liverpool score, C-reactive protein, albumins, and fibrinogen were ranked. The rankings were performed in four ways: The first two were based on the Kaplan-Meier method (log-rank statistics and the definite integral IS between two survival curves). The next method of ranking was based on univariate and multivariate Cox regression analyses. Results: The ranks were as follows: the radicality of liver resection (rank 1), lymph node infiltration of primary colorectal cancer (rank 2), elevated C-reactive protein (rank 3), the American Society of Anesthesiologists Classification grade (rank 4), the right-sidedness of primary colorectal cancer (rank 5), the multiplicity of colorectal liver metastases (rank 6), the size of colorectal liver metastases (rank 7), albumins (rank 8), and fibrinogen (rank 9). Conclusions: The ranking methodologies resulted in almost the same ranking order of the variables. Elevated C-reactive protein was ranked highly and can be considered a relevant replacement for the neutrophil–lymphocyte ratio in the Liverpool score. These methods are suitable for ranking variables in similar models for medical research.

    Outcomes of the surgical treatment for adenocarcinoma of the cardia – single institution experience

    by Stojan Potrc, Arpad Ivanecz, Bojan Krebs, Urska Marolt, Bojan Iljevec, Tomaz Jagric

    Adenocarcinomas at the cardia are biologically aggressive tumors with poor long-term survival following curative resection. For resectable adenocarcinoma of the cardia, mostly esophagus extended total gastrectomy or esophagus extended proximal gastric resection is performed; however, the surgical approach, transhiatal or transthoracic, is still under discussion. Postoperative morbidity, mortality and long-term survival were analyzed to evaluate the potential differences in clinically relevant outcomes. Of altogether 844 gastrectomies performed between January 2000 and December 2016, 166 were done for the adenocarcinoma of the gastric cardia, which we analyzed with using the Cox proportional hazards model. 136 were esophagus extended total gastrectomy and 125 esophagus extended proximal gastric resection. A D2 lymphadenectomy was performed in 88.2%, splenectomy in 47.2%, and multivisceral resections in 12.4% of patients. R0 resection rate was 95.7%. The mean proximal resection margin on the esophagus was 42.45 mm. It was less than 21 mm in 9 patients. Overall morbidity regarding Clavien-Dindo classification (> 1) was altogether 28.6%. 15.5% were noted as surgical and 21.1% as medical complications. The 30-day mortality was 2.2%. The 5-year survival for R0 resections was 33.4%. Multivisceral resection, depth of tumor infiltration, nodal stage, and curability of the resection were identified as independent prognostic factors. Transhiatal approach for resection of adenocarcinoma of the cardia is a safe procedure for patients with Siewert II and III regarding the postoperative morbidity and mortality; moreover, long-term survival is comparable to transthoracic approach. The complications associated with thoracoabdominal approach can therefore be avoided with no impact on the rate of local recurrence.

    Impact factors for perioperative morbidity and mortality and repercussion of perioperative morbidity and long-term survival in pancreatic head resection

    by Stojan Potrc, Arpad Ivanecz, Vid Pivec, Urska Marolt, Sasa Rudolf, Bojan Iljevec, Tomaz Jagric

    Background: The focus of the present study was to reveal any impact factors for perioperative morbidity and mortality as well as repercussion of perioperative morbidity on long-term survival in pancreatic head resection.Patients and methods: In a retrospective study, clinic-pathological factors of 240 patients after pancreatic head (PD) or total resection were analyzed for correlations with morbidity, 30- and 90-day mortality, and long-term survival. According to Clavien–Dindo classification, all complications with grade II and more were defined as overall complications (OAC). OAC, all surgical (ASC), general (AGC) and some specific types of complications like leaks from the pancreatoenteric anastomosis (PEA) or pancreatic fistula (PF, type A, B and C), leaks from other anastomoses (OL), bleeding (BC) and abscesses (AA) were studied for correlation with clinic-pathological factors.Results: In the 9-year period, altogether 240 patients had pancreatic resection. The incidence of OAC was 37.1%, ASC 29.2% and AGC 15.8%. ASC presented themselves as PL, OL, BC and AA in 19% (of 208 PD), 5.8%, 5.8%, and 2.5% respectively. Age, ASA score, amylase on drains, and pancreatic fistulas B and C correlated significantly with different types of complications. Overall 30- and 90-day mortalities were 5 and 7.9% and decreased to 3.5 and 5% in P2.Conclusions: High amylase on drains and higher mean age were independent indicators of morbidity, whereas PL and BC revealed as independent predictor for 30-day mortality, and physical status, OAC and PF C for 90-day mortality.

    Aortoduodenal fistula three years after aortobifemoral bypass: case report and literature review.

    by Urska Marolt, Stojan Potrc, Andrej Bergauer, Nuhi Arslani, Dino Papes

    Secondary aortoenteric fistulas (SAEF) are a relatively rare but dangerous complication of aortal reconstructive surgery. We present a patient that underwent aortobifemoral bypass three years before developing the signs of aortoenteric fistula, and we reviewed the literature on the topic. Since the clinical signs are nonspecific, physicians should have a high index of suspicion for SAEF in patients who underwent aortal reconstructive surgery. The most useful diagnostic tools for stable patients are upper gastrointestinal endoscopy and computed tomography scan with contrast that can, in combination with history and clinical signs, enable accurate diagnosis in more than 90% of patients. Unstable patients with suspected aortoenteric fistula should undergo exploratory laparotomy. The treatment of choice is open surgery with graft excision, wide debridement of infected tissue, bowel repair or resection followed by an extra-anatomic bypass or in situ placement of a new graft. Early postoperative mortality remains high, around 30% in most analyses. Currently there are no guidelines for the diagnosis and management of SAEF, so individualized approach is necessary for each patient.

    Rectal cancer treatment and survival--comparison of two 5-year time intervals.

    by Bojan Krebs, Miran Kozelj, Stojan Potrc

    In last two decades there was a huge step forward concerning rectal cancer treatment. The aim of our study was comparison of two time intervals regarding the methods of treatment and results of radical rectal cancer surgery. 407 patients operated on for rectal cancer were included in study. Those were patients with elective radical resection of solitary rectal tumor who survived first month after the operation. Patients were divided in two groups regarding the time of operation. In group one were patients operated on between 1996 and 2000 and in group two patients operated on between 2001 and 2005. We compared our results in both intervals with special interest about type of operation considering localization of the tumor, local recurrence and cancer related survival. Significant differences were found between two groups. There were more sphincter saving operations in second group, less local recurrences and better survival than in first group. This study observed significant improvements at recurrence rates and total survival for patients operated on rectal cancer.
