Audio Stimuli

In this paper, we argue that moving away from written stimuli in acceptability judgment experiments is a necessary step to address the systematic exclusion of particular empirical phenomena, languages/varieties, and speakers in (psycho)linguistics (e.g., Anand, Chung, & Wagers 2011). We provide user-friendly guidelines for conducting acceptability experiments which use audio stimuli in three platforms: Praat, Qualtrics, and PennController for Ibex (Zehr & Schwarz 2018). Finally, we qualitatively compare the results of two experiments investigating English constituent order using audio and written stimuli. We hope this paper will not only increase the types of languages, speakers, and phenomena which are included in experimental syntax, but help researchers who are interested in conducting experiments overcome the initial learning curve.

Summary This study aimed to demonstrate the learning curve of robot-assisted minimally invasive esophagectomy (RAMIE). A retrospective analysis of the first 124 consecutive patients who underwent RAMIE with intrathoracic anastomosis (Ivor Lewis) by a single surgeon between May 2015 and August 2020 was performed. An risk-adjusted cumulative sum (RA-CUSUM) analysis was applied to generate a learning curve of RAMIE considering the major complication rate, which reflected the technical proficiency. The overall 30-day morbidity rate was 38.7%, while the major complication rate was 25.8%. The learning curve was divided into two phases based on the RA-CUSUM analysis: phase I, the initial learning phase (cases 1–51) and phase II, the proficiency phase (cases 52–124). As we compared the proficiency phase with the initial learning phase, significantly decreased trends were observed in relation to the major complication rate (37.3% vs. 18.7%, P = 0.017), total operation time (330.9 ± 55.6 vs. 267.3 ± 39.1 minutes, P < 0.001), and length of hospitalization (10 [IQR, 9–14] days vs. 9 [IQR, 8–11] days, P = 0.034). In conclusion, the learning curve of RAMIE consisted of two phases, and at least 51 cases were required to gain technical proficiency.

Aims and Objectives: In the past years, further development in knee replacement still continues. Computer-assisted surgery techniques in total knee arthroplasty (TKA) are on the rise. One point of criticism is the prolonged time of surgery and associated cost as known from old techniques like navigation. The primary objective of this study was to determine the learning curve for the time of surgery and accuracy in implant positioning for an imageless robotic system for TKA. Materials and Methods: In this prospective study, the first 30 robotic-assisted TKA from a single senior surgeon were analyzed with regard to time of surgery and accuracy of implant position on the basis of the intraoperative plan and the postoperative x-rays. This data was compared to the last 30 manual TKAs of the same surgeon with the same prosthesis. Evaluation of the learning curve was performed with CUSUM analysis. The time of surgery after finishing the learning curve in the robotic group was compared to the manual group. Results: The learning curve in the robotic group for surgery time was finished after 11 cases. The robotic experience did not affect the accuracy of implant positioning, such as limb alignment and restoration of the joint line. The mean absolute deviation of the postoperative limb alignment to the intraoperative plan was 2° (+/- 1,1). The mean absolute deviation of the medial proximal tibial (mPTA) and distal lateral femoral angle (dLFA) was 1° (+/- 0,9) for both. The mean surgery time in the robotic group after finishing the learning curve was 66 minutes (+/- 4,2) and in the total manual group 67 minutes (+/- 3,5) (n.s.). Conclusion: After finishing the initial learning curve of 11 cases for robotic-assisted TKA the time of surgery is equal to the manual conventional technique. However, there is no learning curve for implant positioning with the imageless robotic system. The implementation of the intraoperative plan is accurate to 1° with the robotic system.

Laparoscopic Anastomosis

This study evaluated the learning curve for a second-year general surgery resident and compared 2 totally laparoscopic aortic surgery techniques in 10 pigs: the transretroperitoneal apron approach and the transperitoneal retrocolic approach. Five end points were compared: success rate, percentage of conversion, time required, laparoscopic anastomosis quality, and learning curve. The first 3 interventions required an open conversion. The last 7 were done without complications. Mean dissection time was significantly higher with the apron approach compared with the retrocolic approach. The total times for operation, clamping, and arteriotomy time were similar. All laparoscopic anastomoses were patent and without stenosis. The initial learning curve for laparoscopic anastomosis was relatively short for a second-year surgery resident. Both techniques resulted in satisfactory exposure of the aorta and similar mean operative and clamping time. Training on an ex vivo laparoscopic box trainer and on an animal model seems to be complementary to decrease laparoscopic anastomosis completion time.

Open Pancreaticoduodenectomy

Abstract Background : To analyze the initial learning curve (LC) for robot-assisted pancreaticoduodenectomy (RAPD) and compare RAPD during the initial LC with open pancreaticoduodenectomy (OPD) in terms of outcome. Methods : This study is a retrospective review of patients who consecutively underwent RAPD between October 2015 and May 2019 in our hospital. Experiences from 30 initial consecutive RAPD cases, considered the initial LC of a single surgeon team, were compared with those from laparotomy cases during the same period in terms of outcome. Preoperative demographic and comorbidity data were obtained. Perioperative data on operation time, blood transfusion, numbers of harvested lymph nodes, 90-day mortality and readmission, surgery-related complications, postoperative hospital stay, and total costs were acquired for analysis. The operation time for RAPD was evaluated using the cumulative sum(CUSUM) method. Results : Seventy-eight patients, including 30 consecutive RAPD cases and 48 consecutive open cases, were enrolled for review. The demographic and comorbidity characteristics of the two groups were similar. Compared with OPD, RAPD required a significantly longer operative time (423.67 ± 137.627 min vs. 228.75 ± 44.988 min, P < 0.001) and higher cost (185700 ± 54500 RMB vs. 120600 ± 41700 RMB, P < 0.001). Moreover, compared with the OPD group, the RAPD group revealed a significantly smaller mean number of lymph nodes harvested in malignant cases (8.72 ± 4.9 vs 14.26 ± 7.633, P = 0.007). No statistically significant differences were observed between the two groups in terms of incidence of Clavien–Dindo grade III–V morbidities and 90-day mortality and readmission. In the CUSUM graph, one peak point was observed at the 8th case, after which the operation time began to decrease. Conclusions : RAPD is safe when performed in well-selected patients by well-trained teams with extensive experience in open pancreaticoduodenectomy during the initial LC,and the LC of RAPD may be shorten less than 30 cases.
