Abstract
INTRODUCTION The objective of this systematic review of the literature is to compare a selection of currently utilized disposable and reusable laparoscopic medical devices in terms of safety (1st criteria), cost and carbon footprint. MATERIAL AND METHODS A search was carried out on electronic databases for articles published up until 6 May 2022. The eligible works were prospective (randomized or not) or retrospective clinical or medical-economic comparative studies having compared disposable scissors, trocars, and mechanical endoscopic staplers to the same instruments in reusable. Two different independent examiners extracted the relevant data. RESULTS Among the 2882 articles found, 156 abstracts were retained for examination. After comprehensive analysis concerning the safety and effectiveness of the instruments, we included four articles. A study on trocars highlighted increased vascular complications with disposable instruments, and another study found more perioperative incidents with a hybrid stapler as opposed to a disposable stapler. As regards cost analysis, we included 11 studies, all of which showed significantly higher costs with disposable instruments. The results of the one study on carbon footprints showed that hybrid instruments leave four times less of a carbon footprint than disposable instruments. CONCLUSION The literature on the theme remains extremely limited. Our review demonstrated that from a medical and economic standpoint, reusable medical instruments, particularly trocars, presented appreciable advantages. While there exist few data on the ecological impact, those that do exist are unmistakably favorable to reusable instruments.

[PMID: 35881243 PMCID: PMC9652209 DOI: 10.1007/s00464-022-09411-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 06/19/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Triangle pancreatoduodenectomy adds to the conventional procedure the en bloc removal of the retroperitoneal lympho-neural tissue included in the triangular area bounded by the common hepatic artery (CHA), the superior mesenteric artery (SMA), and the superior mesenteric vein/portal vein. We herein aim to show the feasibility of "cold" triangle robotic pancreaticoduodenectomy (C-Tr-RPD) for pancreatic cancer (PDAC). METHODS Cold dissection corresponds to sharp arterial divestment performed using only the tips of robotic scissors. After division of the gastroduodenal artery, triangle dissection begins by lateral-to-medial divestment of the CHA and anterior-to-posterior clearance of the right side of the celiac trunk. Next, after a wide Kocher maneuver, the origin of the SMA, and the celiac trunk are identified. After mobilization of the first jejunal loop and attached mesentery, the SMA is identified at the level of the first jejunal vein and is divested along the right margin working in a distal-to-proximal direction. Vein resection and reconstruction can be performed as required. C-Tr-RPD was considered feasible if triangle dissection was successfully completed without conversion to open surgery or need to use energy devices. Postoperative complications and pathology results are presented in detail. RESULTS One hundred twenty-seven consecutive C-Tr-RPDs were successfully performed. There were three conversions to open surgery (2.3%), because of pneumoperitoneum intolerance (n = 2) and difficult digestive reconstruction. Thirty-four patients (26.7%) required associated vascular procedures. No pseudoaneurysm of the gastroduodenal artery was observed. Twenty-eight patients (22.0%) developed severe postoperative complications (≥ grade III). Overall 90-day mortality was 7.1%, declining to 2.3% after completion of the learning curve. The median number of examined lymph nodes was 42 (33-51). The rate of R1 resection (7 margins < 1 mm) was 44.1%. CONCLUSION C-Tr-RPD is feasible, carries a risk of surgical complications commensurate to the magnitude of the procedure, and improves staging of PDAC.

Abstract
BACKGROUND With the rise in distal radius fracture (DRF) incidence and treatment through open reduction internal fixation, there are increasing concerns in the current medical cost containment climate. To help reduce costs, manufacturers are introducing sterile packed kits. The purpose of this study is to compare the costs of the single use kit (SK) against conventional reprocessed DRF surgical sets (RS). METHODS A four-year retrospective review at three surgical centers was performed to determine a company's RS average sterilization and processing costs. RS instrumentation cost was estimated by straight-line depreciation from the original purchase price. RS implant costs were calculated from the list price. SK list cost was obtained from the same company. Incidence of surgical delays was estimated by a survey of 23 hand surgeons and cost of delays was obtained from surgical center reports. Sensitivity analysis on delay frequency was performed to assess a range of overall costs. RESULTS OR delays were estimated at one out of 100 cases, with an average cost of $11 per case. For RS, average instruments, implants, and sterilization costs per case was $47, $2882, and $39. The total RS cost of $2,978 and the SK was $1,667 with a difference of $1,313 per case. CONCLUSION RS was found to cost $1,313 more per case than the SK in an ambulatory surgical setting and potentially more cost effective. Ultimately, pricing is highly variable at each center based on negotiated and contractual pricing.

Abstract
Choledochoscopy, or cholangioscopy, is an endoscopic procedure for direct visualization within the biliary tract for diagnostic or therapeutic purposes. Since its conception in 1879, many variations and improvements are made to ensure relevance in diagnosing and managing a range of intrahepatic and extrahepatic biliary pathologies. This ranges from improved visual impression and optical guided biopsies of indeterminate biliary strictures and clinically indistinguishable pathologies to therapeutic uses in stone fragmentation and other ablative therapies. Furthermore, with the evolving understanding of biliary disorders, there are significant innovative ideas and techniques to fill this void, such as nuanced instances of biliary stenting and retrieving migrated ductal stents. With this in mind, we present a review of the current advancements in choledo-choscopy with new supporting evidence that further delineates the role of choledochoscopy in various diagnostic and therapeutic interventions, complications, limitations and put forth areas for further study.

Abstract
BACKGROUND Nickel-titanium (NiTi) open coils are common tools in fixed orthodontic treatments to apply light and continuous forces. Their favorable mechanical properties and their relatively high cost have prompted many clinicians to decide to reuse them. AIM The present study aimed to evaluate the effect of 10% hydrochloric acid (HCl) and 5.25% sodium hypochlorite (NaClO) solution and sterilization, on the unloading force of NiTi open-coils. MATERIALS AND METHODS This experimental in vitro study consisted of 160 NiTi open coils from two brands of Highland Metals and Masel were provided. Each group was randomly divided into four subgroups: control, three rounds of immersion, three rounds of autoclave sterilization, and three rounds of immersion and autoclaving. Each round of immersion process included 1 min in 10% HCl, followed by 5 min in 5.25% NaClO. Spring was compressed for 4 mm. Then, the unloading forces of each spring were recorded at 4, 3, 2, and 1 mm of compression, respectively. The data were analyzed with SPSS (P < 0.05), using one-way ANOVA and independent t-test. RESULTS One-way ANOVA showed a significant difference in the 2-mm compression of Group 1 and 3-mm compressions of Groups 1 and 2 compared to the control group in the Highland metals brand (P < 0.04, P < 0.014, and P < 0.007, respectively). There was no significant difference between the different compressed lengths and groups in the Masel brand. CONCLUSION One-minute immersion in 10% HCL and 5-min immersion in 5.25% NaOCl, followed by autoclave sterilization, even after repeating the process three times, did not significantly change the force properties of NiTi open springs. Therefore, the re-use of these springs with the above-mentioned method as preparation can be recommended.

Abstract
INTRODUCTION Clinical benefits of laparoscopic surgery are well established, but evidence for financial benefits is limited. This study aimed to compare the financial impact of the introduction of laparoscopic colorectal surgery. METHODS This study included patients who underwent colorectal surgery between January 2010 and 2015. We collected a range of financial data and divided the patients into 2 groups. Primary outcome was total cost defined by surgical-related costs. RESULTS A total of 1,246 patients were included, of which 440 surgeries were performed laparoscopically. The total median cost of laparoscopy was higher compared to open surgery (EUR 4,665 vs. EUR 4,268, p = 0.001). Laparoscopy was associated with higher equipment costs (EUR 857 vs. EUR 232, p < 0.001), longer operating time (3.2 vs. 2.5 hours, p < 0.001), and more readmissions (10.9 vs. 8.5%, p < 0.001). However, after adjusting for heterogeneity, no difference was found in total cost. Surgical-related costs were counterbalanced by lower costs associated with shorter median hospital stay (6 vs. 9 days, p < 0.001), less morbidity (37.3 vs. 55.1%, p < 0.001), and less mortality (1.8 vs. 5.6%, p = 0.013) for laparoscopy. CONCLUSION During the introduction of laparoscopy for colorectal surgery, no significant differences were found in total cost between laparoscopic and open colorectal surgery. However, favorable postoperative outcomes were achieved with laparoscopic surgery.

Abstract
INTRODUCTION Some countries have implemented reuse of laparoscopic instruments for cost-effective purposes. An accurate cleaning as the first step of reprocessing would lead to the effective sterilization. The purpose was to evaluate the effect of cleaning guidelines implementation on microbial load of laparoscopic instruments which were used in laparoscopic cholecystectomy surgery. METHODS This experimental study was done in an educational hospital, in 2017 and included a total of 128 laparoscopic instruments randomly selected from cholecystectomy surgeries and divided into two cleaning groups. The instruments were checked out in terms of number (colony-forming units [CFU]/mL) and type of microorganisms in two groups of routine cleaning and according to guideline cleaning. This guideline was indigenous and taken from successful instruction in this context that was presented by the Association for the Advancement of Medical Instrumentation (AAMI). The appropriate statistical analysis was conducted by SPSS version 19. RESULTS The average microbial load was 2.4 × 106 CFU/100 mL after clinical use. It was reduced to 7.2 × 105 CFU/100 mL in the control group and 3.4 × 104 CFU/100 mL in the intervention group, after the cleaning process. The most common microorganisms that were isolated immediately after clinical use were Escherichia coli 81.2%, Pseudomonas 68.8%, Klebsiella 57.8%, and spp., and so on. CONCLUSION The AAMI cleaning method is recommended to be utilized by operating room nurses for laparoscopic instruments.

Abstract
PURPOSE Healthcare facilities could minimize the cost of surgical instrument and implant processing by using single-use devices. The main objective was to prospectively compare the total cost of a single-use and reusable device used in short lumbar spine fusion. METHODS A 1-year, single-centre, prospective study was performed on patients requiring a one- or two-level lumbar arthrodesis. Patients were randomized in two groups treated with either reusable or single-use device. A cost minimization analysis was performed using a micro-costing approach from a hospital perspective. Every step of the preparation process was timed and costed based on hourly wages of hospital employees, cleaning supplies and hospital waste costs. RESULTS Forty cases were evaluated. No significant difference in operation time was noted (reusable 176.1 ± 68.4 min; single use 190.4 ± 71.7 min; p = 0.569). Mean processing time for single-use devices was lower than for reusable devices (33 min vs. 176 min) representing a cost of 14€ versus 58€ (p < 0.05). Pre-/post-sterilization and spinal set recomposing steps were the most time-consuming in reusable device group. A total cost saving of 181€ per intervention resulted from the use and processing of the single-use device considering an additional sterilization cost of 137€ with the reusable device. The weight of the reusable device was 42 kg for three containers and 1.2 kg for the single-use device. CONCLUSIONS Owing to the absence of re-sterilization, single-use devices in one- and two-level lumbar fusion allow significant money and time savings. They may also avoid delaying surgery in case of reusable device unavailability.

Abstract
Background Although the effect of the recent Greek economic crisis and austerity on the population’s health and the health system effectiveness have been discussed a lot recently, data on common surgical conditions affecting large part of the population are missing. Using inguinal hernia as a model we investigated possible changes of citizens’ attitude regarding the time of referral, the perioperative details and the intraoperative findings of the emergency hernioplasties. Methods The present retrospective study was conducted by a Department of Surgery in a tertiary public hospital of the Greek capital. We reviewed the records of all hernioplasties performed during two 5-year periods: 2005–2009 and 2012–2016, i.e. before and during the crisis focusing on the emergency ones (either incarcerated or strangulated). Results An equal number of hernioplasties was performed in both periods. During the crisis however, an emergency hernioplasty was significantly more probable (HR 1.269, 95% CI 1.108–1.1454, p = 0.001), at a younger age (p = 0.04), mainly in patients younger than 75 years old (p = 0.0013). More patients presented with intestinal ischemia (7 vs 18, p = 0.002), requiring longer hospitalization (5.2 vs 9.6 days, p = 0.04), with higher cost (560 ± 262.4€ vs 2125 ± 1180.8€ p < 0.001). In contrast the percentage of patients with intestinal resection, their hospitalization length and treatment-cost remained unchanged. During the crisis there was a non-significant increase of emergency patients requiring ICU postoperatively (0 vs 4, p = 0.07) and a non-significant 60% increase of emergency operations in migrants/refugees population (3.5% vs 5.8%, p = 0.28). Epidural anesthesia was significantly more frequent during the crisis. Conclusion During the crisis: (i) the emergency hernioplasties increased significantly, (ii) more patients (exclusively Greek) presented with intestinal ischemia requiring longer hospitalization and higher treatment cost, (iii) the mean age of the urgently treated patients decreased significantly (iv) regional (epidural) anesthesia was more frequent. Although a direct causal relation could not be proven by the present study most observations can be explained by an increase of the patients who delayed the elective treatment of their hernia, and by a redistribution of the surgical workload towards big central hospitals. This can be prevented by adequately supporting the small district hospitals.

Abstract
OBJECTIVE Lumbar arthrodesis is a common surgical technique that consists of the fixation of one or more motion segments with pedicle screws and rods. However, spinal surgery using these techniques is expensive and has a significant impact on the budgets of hospitals and Healthcare Systems. While reusable and disposable instruments for laparoscopic interventions have been studied in literature, no specific information exists regarding instrument kits for lumbar arthrodesis. The aim of the present study was to perform a complete health technology assessment comparing a disposable instrument kit for lumbar arthrodesis (innovative device) with the standard reusable instrument. METHODS A prospective and observational study was implemented, by means of investigation of administrative records of patients undergoing a lumbar arthrodesis surgical procedure. The evaluation was conducted in 2013, over a 12- month time horizon, considering all the procedures carried out using the two technologies. A complete health technology assessment and a multi-criteria decision analysis approach were implemented in order to compare the two alternative technologies. Economic impact (with the implementation of an activity based costing approach), social, ethical, organisational, and technology-related aspects were taken into account. RESULTS Although the cost analysis produced similar results in the comparison of the two technologies (total cost equal to € 4,279.1 and € 4,242.6 for reusable instrument kit and the disposable one respectively), a significant difference between the two instrument kits was noted, in particular concerning the organisational impact and the patient safety. CONCLUSIONS The replacement of a reusable instrument kit for lumbar arthrodesis, with a disposable one, could improve the management of this kind of devices in hospital settings.

Abstract
We investigate the inventory management practices for reusable surgical instruments that must be sterilized between uses. We study a hospital that outsources their sterilization services and model the inventory process as a discrete-time Markov chain. We present two base-stock inventory models, one that considers stockout-based substitution and one that does not. We derive the optimal base-stock level for the number of reusable instruments to hold in inventory, the expected service level, and investigate the implied cost of a stockout. We apply our theoretical results to a dataset collected from a surgical unit at a large tertiary care hospital specializing in colorectal operations. We demonstrate how to implement our model when determining base-stock levels for future capacity expansion and when considering alternative stockout protocols. Our analysis suggests that the hospital can reduce the number of reusable instrument sets held in inventory if on-site sterilization techniques (e.g., flash sterilization) are employed. Our results will guide future procurement decisions for surgical units based on costs and desired service levels.

Abstract
PURPOSE Over 300,000 ventral hernia repairs (VHRs) are performed each year in the US. We sought to assess the economic burden related to ventral hernia recurrences with a focused comparison of those with the initial open versus laparoscopic surgery. METHODS The Premier Alliance database from 2009 to 2014 was utilized to obtain patient demographics and comorbid indices, including the Charlson comorbidity index (CCI). Total hospital cost and resource expenses during index laparoscopic and open VHRs and subsequent recurrent repairs were also obtained. The sample was separated into laparoscopic and open repair groups from the initial operation. Adjusted and propensity score matched cost outcome data were then compared amongst groups. RESULTS One thousand and seventy-seven patients were used for the analysis with a recurrence rate of 3.78 %. For the combined sample, costs were significantly higher during recurrent hernia repair hospitalization ($21,726 versus $19,484, p < 0.0001). However, for index laparoscopic repairs, both the adjusted total hospital cost and department level costs were similar during the index and the recurrent visit. The costs and resource utilization did not go up due to recurrence, even though these patients had greater severity during the recurrent visit (CCI score 0.92 versus 1.06; p = 0.0092). Using a matched sample, the total hospital recurrence cost was higher for the initial open group compared to laparoscopic group ($14,520 versus $12,649; p = 0.0454). CONCLUSIONS Based on our analysis, need for recurrent VHR adds substantially to total hospital costs and resource utilization. Following initial laparoscopic repair, however, the total cost of recurrent repair is not significantly increased, as it is following initial open repair. When comparing the initial laparoscopic repair versus open, the cost of recurrence was higher for the prior open repair group.
