ABSTRACT

PURPOSE: Laparoscopic techniques have been used and refined in hernia surgery for several years. The aim of this study was to compare an established method such as laparoscopic intra-peritoneal onlay mesh repair (lap. IPOM) with ventral Transabdominal Preperitoneal Patch Plasty (ventral-TAPP) in abdominal wall hernia repair. METHODS: Patient-related data of 180 laparoscopic ventral hernia repairs between June 2014 and August 2020 were extracted from our prospectively maintained database. Of these patients, 34 underwent ventral-TAPP and 146 lap. IPOM. After excluding hernias with a defect size > 5 cm and obtaining balanced groups with propensity-score matching, a comparative analysis was performed in terms perioperative data, surgical outcomes and cost-effectiveness. RESULTS: Propensity-score matching suggested 27 patients in each of the two cohorts. The statistical evaluation showed that intake of opiates was significantly higher in the lap. IPOM group compared to ventral-TAPP patients (p = 0.001). The Visual Analogue Scale (VAS) score after lap. IPOM repair was significantly higher at movement (p = 0.008) and at rest (p = 0.023). Also, maximum subjective pain during hospital stay was significantly higher in the lap. IPOM group compared to ventral-TAPP patients (p = 0.004). No hernia recurrence was detected in either group. The material costs of ventral-TAPP procedure (34.37 ± 0.47 €) were significantly lower than those of the lap. IPOM group (742.57 ± 128.44 € p = 0.001). The mean operation time was 65.19 ± 26.43 min in the lap. IPOM group and 58.65 ± 18.43 min in the ventral-TAPP cohort. Additionally, the length of hospital stay in the lap. IPOM cohort was significantly longer (p = 0.043). CONCLUSION: Ventral-TAPP procedures represent an alternative technique to lap. IPOM repair to reduce the risk of complications related to intra-peritoneal position of mesh and fixating devices. In addition, our study showed that postoperative pain level, material costs and hospital stay of the ventral-TAPP cohort are significantly lower compared to lap. IPOM patients.

ABSTRACT

Against the background of the growing economization of clinical medicine, in the last decades the topics of risk and complication management have also become more important in surgical disciplines. The standardization and reproducible documentation of outcome and complication data play a key role for valid quality control. In this article a digital system implemented at the surgical clinic of the Charité University Medicine in Berlin is analyzed with respect to its practicability for perioperative and postoperative monitoring of complications within the framework of quality assurance.

ABSTRACT

INTRODUCTION: As in the rest of the world, in Germany, inguinal hernia operations are among the most common operations. From an economic standpoint, very little is known about the influence of demographic, clinical or hernia-related parameters on the cost of inguinal hernia repair. We, therefore, evaluated individual patient parameters associated with higher costs with a special focus on multimorbidity. METHODS: A total of 916 patients underwent hernia repair for primary or recurrent inguinal hernia between 2014 and 2017 at a single university center and were included in the analysis. The clinical and financial data of these patients were analyzed to identify cost-increasing parameters. RESULTS: A majority of patients were male (90.7%), with a mean age of 55 years. The surgical methods utilized were mainly the TAPP (57.2%) and Lichtenstein (41.7%) procedures, with an average duration of surgery of 85 min and an average duration of anesthesia of 155 min. The mean cost of all procedures was 3338.3 € (± 1608.1 €). Older age, multimorbidity, emergency operations with signs of incarceration, longer hospital stays and postoperative complications were significant cost-driving factors. On the other hand, sex, the side of the hernia (left vs. right) and the presence of recurrent hernias had no influence on the overall direct costs. CONCLUSION: From a purely economic point of view, older age and multimorbidity are demographic cost-driving factors that cannot be influenced. The national hospital reimbursement system needs to consider and compensate for these factors. Emergency operations need to be prevented by early elective treatment. Long postoperative stays and postoperative complications need to be prevented by proper preoperative check-ups and accurate treatment.

ABSTRACT

BACKGROUND: Minimally invasive techniques have been broadly introduced to liver surgery during the last couple of years. In this study, we aimed to report the incidence and potential risk factors for incisional hernia (IH) as well as health-related quality of life (HRQoL) after laparoscopic liver resections (LLR). METHODS: All patients undergoing LLR between January 2014 and June 2017 were contacted for an outpatient hernia examination. In all eligible patients, photo documentation of the scar was performed and IH was evaluated by clinical examination and by ultrasound. Patients also completed a questionnaire to evaluate IH-specific symptoms and HRQoL. Obtained results were retrospectively analyzed with regard to patients' characteristics, perioperative outcomes and applied minimally invasive techniques, such as multi-incision laparoscopic liver surgery or hand-assisted/single-incision laparoscopic surgery (HALS/SILS). RESULTS: Of 184 patients undergoing surgery, 161 (87.5%) met the inclusion criteria and 49 patients (26.6%) participated in this study. After a median time of 26 months (range 19-50 months) after surgery, we observed an overall incidence of IH of 12%. Five of 6 patients were overweight or obese (BMI ≥ 25) and 5 of 6 hernias were located at the umbilical site. Univariate analysis suggested the performance status at time of operation (ASA score ≥ 3; HR 5.616, 95% CI 1.012-31.157, p = 0.048) and the approach (HALS/SILS, HR 6.571, 95% CI 1.097-39.379, p = 0.039) as potential risk factors for IH. A higher frequency of hernia-related physical restrictions (HRR; p = 0.058) and a decreased physical functioning (p = 0.17) were noted in patients with IH; however, both being short of statistical significance. CONCLUSION: Advantages of laparoscopic surgery with regard to low rates of IH can be translated to minimally invasive liver surgery. Even though there are low rates of IH, patients with poor performance status at the time of operation should be monitored closely. While patients' characteristics are hard to influence, it might be worth focusing on surgical factors such as the approach and the closure of the umbilical site to further minimize the rate of IH.

ABSTRACT

INTRODUCTION: Elective and emergency inguinal hernia surgery is a central task for general and abdominal surgeons. As a standard procedure it is regarded as having a relatively low income in the German diagnosis-related groups (DRG) system. This can lead to an economic imbalance, especially in a cost-intensive environment of a university hospital. The aim of this analysis was to investigate the influence of clinical factors on costs and the contribution margin as well as the overall economic evaluation of elective inguinal hernia surgery at a university hospital. MATERIAL AND METHODS: All patients undergoing elective inguinal hernia surgery at two locations of the Charité University Medicine Berlin in 2014 and 2015 were included in the analysis. The influence of clinical, patient and surgical factors on the economic outcome of the cases was evaluated. RESULTS: A total of 419 patients were included, mostly after a Lichtenstein operation (44.9%) and laparoscopic transabdominal preperitoneal (TAPP) surgery (53.9%). The greatest impact on the economic outcome was the occurrence of postoperative complications. Also, a patient clinical complexity level (PCCL) value of >1, more than 8 encoded secondary diagnoses and a duration of hospital stay of less than 2 days had a significantly negative impact on the contribution margin. Overall, elective inguinal hernia surgery led to a negative contribution margin of €â€¯651 per case. CONCLUSION: Elective inguinal hernia surgery in the environment of a university hospital has a high financial deficit; however, since a complete discontinuation of this treatment is not an alternative multifactorial approaches are required to improve the economic outcome.

ABSTRACT

OBJECTIVES: The Model for End-Stage Liver Disease score and King's College Hospital (KCH) criteria are accepted prognostic models acute liver failure (ALF), while the use of (APACHE) scores predict to outcomes of emergency liver transplantation is rare. MATERIALS AND METHODS: The present study included 87 patients with ALF who underwent liver transplantation. We calculated (KCH) criteria, as well as MELD, APACHE II, and APACHE III scores at the listing date for comparison with 3-month outcomes. RESULTS: According to the Youden-Index, the best cut-off value for the APACHE II score was 8.5 with 100% sensitivity, 49% specificity, 24% positive predictive value (PPV), and 100% negative predictive value (NPV). Patients with <8.5 points had a significantly higher survival rate (P < .05). The proposed APACHE III cut-off was 80. The APACHE III score demonstrated the highest specificity and PPV (90% specificity, 50% PPV). The NPV was 92%. With a 90-point threshold the specificity increased to 98% with 75% PPV and 89% NPV. Only 1 of 4 patients with a score >90 survived transplantation (P = .001). MELD score and KCH criteria were not significant (P > .05). According to the Hosmer-Lemeshow test, only the APACHE III score adequately describe the data. CONCLUSIONS: The APACHE III score was superior to KCH criteria, MELD score, and APACHE II score to predict outcomes after transplantation for ALF. It is a valuable parameter for pretransplantation patient selection.
