Laparoscopic versus open appendectomy: a retrospective cohort study assessing outcomes and cost-effectiveness.

ABSTRACT: Appendectomy is the most common surgical procedure performed in emergency surgery. Because of lack of consensus about the most appropriate technique, appendectomy is still being performed by both open (OA) and laparoscopic (LA) methods. In this retrospective analysis, we aimed to compare the laparoscopic approach and the conventional technique in the treatment of acute appendicitis.Retrospectively collected data from 593 consecutive patients with acute appendicitis were studied. These comprised 310 patients who underwent conventional appendectomy and 283 patients treated laparoscopically. The two groups were compared for operative time, length of hospital stay, postoperative pain, complication rate, return to normal activity and cost.Laparoscopic appendectomy was associated with a shorter hospital stay (2.7?±?2.5 days in LA and 1.4?±?0.6 days in OA), with a less need for analgesia and with a faster return to daily activities (11.5?±?3.1 days in LA and 16.1?±?3.3 in OA). Operative time was significantly shorter in the open group (31.36?±?11.13 min in OA and 54.9?±?14.2 in LA). Total number of complications was less in the LA group with a significantly lower incidence of wound infection (1.4 % vs 10.6 %, P?<0.001). The total cost of treatment was higher by 150 € in the laparoscopic group.The laparoscopic approach is a safe and efficient operative procedure in appendectomy and it provides clinically beneficial advantages over open method (including shorter hospital stay, decreased need for postoperative analgesia, early food tolerance, earlier return to work, lower rate of wound infection) against only marginally higher hospital costs.NCT02867072 Registered 10 August 2016.

Project description:BackgroundTraditionally, uncomplicated acute appendicitis (AA) has been treated with appendectomy. However, the surgical alternatives might carry out significant complications, impaired quality of life, and higher costs than nonoperative treatment. Consequently, it is necessary to evaluate the different therapeutic alternatives' cost-effectiveness in patients diagnosed with uncomplicated appendicitis.MethodsWe performed a model-based cost-effectiveness analysis comparing nonoperative management (NOM) with open appendectomy (OA) and laparoscopic appendectomy (LA) in patients otherwise healthy adults aged 18-60 years with a diagnosis of uncomplicated AA from the payer´s perspective at the secondary and tertiary health care level. The time horizon was 5 years. A discount rate of 5% was applied to both costs and outcomes. The health outcomes were quality-adjusted life years (QALYs). Costs were identified, quantified, and valorized from a payer perspective; therefore, only direct health costs were included. An incremental analysis was estimated to determine the incremental cost-effectiveness ratio (ICER). In addition, the net monetary benefit (NMB) was calculated for each alternative using a willingness to pay lower than one gross domestic product. A deterministic and probabilistic sensitivity analysis was performed.MethodsWe performed a model-based cost-effectiveness analysis comparing nonoperative management (NOM) with open appendectomy (OA) and laparoscopic appendectomy (LA) in patients otherwise healthy adults aged 18-60 years with a diagnosis of uncomplicated AA from the payer's perspective at the secondary and tertiary health care level.

An incremental analysis was estimated to determine the incremental cost-effectiveness ratio (ICER). In addition, the net monetary benefit (NMB) was calculated for each alternative using a willingness to pay lower than one gross domestic product. A deterministic and probabilistic sensitivity analysis was performed.ResultsLA presents a lower cost ($363 ± 35) than OA ($384 ± 41) and NOM ($392 ± 44). NOM exhibited higher QALYs (3.3332 ± 0.0276) in contrast with LA (3.3310 ± 0.057) and OA (3.3261 ± 0.0707). LA dominated the OA. The ICER between LA and NOM was $24,000/QALY. LA has a 52% probability of generating the highest NMB versus its counterparts, followed by NOM (30%) and OA (18%). There is a probability of 0.69 that laparoscopy generates more significant benefit than medical management. The mean value of that incremental NMB would be $93.7 per patient.ConclusionsLA is a cost-effectiveness alternative in the management of patients with uncomplicated AA. Besides, LA has a high probability of producing more significant monetary benefits than NOM and OA from the payer's perspective in the Colombian health system.

Project description:BackgroundCarpal tunnel syndrome is the most common upper-extremity nerve compression syndrome. Over 500,000 carpal tunnel release (CTR) procedures are performed in the U.S. yearly. We estimated the cost-effectiveness of endoscopic CTR (ECTR) versus open CTR (OCTR) using data from published meta-analyses comparing outcomes for ECTR and OCTR.MethodsWe developed a Markov model to examine the cost-effectiveness of OCTR versus ECTR for patients undergoing unilateral CTR in an office setting under local anesthesia and in an operating-room (OR) setting under monitored anesthesia care. The main outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We modeled societal (modeled with a 50-year-old patient) and Medicare payer (modeled with a 65-year-old patient) perspectives, adopting a lifetime time horizon. We performed deterministic and probabilistic sensitivity analyses (PSAs).ResultsECTR resulted in 0.00141 additional QALY compared with OCTR. From a societal perspective, assuming 8.21 fewer days of work missed after ECTR than after OCTR, ECTR cost less across all procedure settings. The results are sensitive to the number of days of work missed following surgery. From a payer perspective, ECTR in the OR (ECTROR) cost $1,872 more than OCTR in the office (OCTRoffice), for an ICER of approximately $1,332,000/QALY. The ECTROR cost $654 more than the OCTROR, for an ICER of $464,000/QALY. The ECTRoffice cost $107 more than the OCTRoffice, for an ICER of $76,000/QALY. From a payer perspective, for a willingness-to-pay threshold of $100,000/QALY, OCTRoffice was preferred over ECTROR in 77% of the PSA iterations. From a societal perspective, ECTROR was preferred over OCTRoffice in 61% of the PSA iterations.ConclusionsFrom a societal perspective, ECTR is associated with lower costs as a result of an earlier return to work and leads to higher QALYs. Additional research on return to work is needed to confirm these findings on the basis of contemporary return-to-work practices. From a payer perspective, ECTR is more expensive and is cost-effective only if performed in an office setting under local anesthesia.Level of evidenceEconomic and Decision Analysis Level I.

Project description:BackgroundThere is no evidence supporting the feasibility of laparoscopic pancreaticoduodenectomy (LPD) compared to open pancreatoduodenectomy (OPD) following neoadjuvant chemotherapy (NACT) for pancreatic ductal adenocarcinoma (PDAC).MethodsThe clinical data of consecutive patients with borderline resectable PDAC who received NACT and underwent either LPD or OPD between January 2020 and December 2022 at Fudan University Shanghai Cancer Center was prospectively collected and retrospectively analyzed.ResultsThe analysis included 57 patients in the OPD group and 20 in the LPD group. Following NACT, the LPD group exhibited a higher median CA19-9 decrease rate compared to the OPD group (85.3% vs. 66.9%, P = 0.042). Furthermore, 3 anatomically borderline PDACs in the LPD group and 5 in the OPD group were downstaged into resectable status (30.0% vs. 12.3%, P = 0.069). According to RECIST criteria, 51 (66.2%) patients in the entire cohort were evaluated as having stable disease. The median operation time for the LPD group was longer than the OPD group (419 vs. 325 min, P < 0.001), while the venous resection rate was 35.0% vs. 43.9%, respectively (P = 0.489). There was no difference in the number of retrieved lymph nodes, with a median number of 18.5 in the LPD group and 22 in the OPD group, and the R1 margin rate (15.0% vs. 12.3%) was also comparable. The incidence of Clavien-Dindo complications (35.0% vs. 66.7%, P = 0.018) was lower in the LPD group compared to the OPD group. Multivariable regression analysis revealed that a tumor diameter > 3 cm before NACT (HR 2.185) and poor tumor differentiation (HR 1.805) were independent risk factors for recurrence-free survival, and a decrease rate of CA19-9 > 70% (OR 0.309) was a protective factor for early tumor recurrence and overall survival.ConclusionsLPD for PDAC following NACT is feasible and oncologically equivalent to OPD. Effective control of CA19-9 levels is beneficial in reducing early tumor recurrence and improving overall survival.
