Transoral thyroidectomy has superior cosmesis and better postoperative voice outcomes than conventional thyroidectomy. However, it usually requires a steep learning curve and longer operative time. Th...
We retrospectively studied 173 consecutive patients who underwent TORT with or without central neck dissection from July 2017 to August 2021. We assessed the TORT learning curve using operative time, ...
Total thyroidectomy operative time was significantly longer than those of lobectomy and isthmusectomy (p < 0.001). In correlation analysis, a significantly positive correlation was observed between bo...
The CUSUM learning curve of TORT was about 52-55 cases, and the operative time, total complication rate, and procedure conversion decreased significantly after the learning curve. The operative time w...
Laparoscopic pyloromyotomy is the preferred surgical management of hypertrophic pyloric stenosis at most centers. We aimed to analyze the learning curve for laparoscopic pyloromyotomy using the experi...
A retrospective review of consecutive patients undergoing laparoscopic pyloromyotomy was performed. All cases were performed with general surgery residents. Cumulative sum (CUSUM) analysis for operati...
A total of 414 patients were included in the analysis as not all surgeons had reached 150 cases at time of analysis. The mean operating time was 29.2 min for all cases across the 5 surgeons. CUSUM ana...
Three distinct phases of learning for laparoscopic pyloromyotomy were identified with no differences in outcomes across the phases. The operating time differed only for the Learning Phase, suggesting ...
Oncoplastic surgery (OPS) is a form of breast conservation surgery involving partial mastectomy followed by volume displacement or replacement surgery. As the field of OPS is growing, we sought to det...
A retrospective chart review was conducted of all patients who underwent OPS over a 6-year period with a single surgeon formally trained in both Plastic Surgery and Breast Oncology. Cumulative summati...
Mean operative time decreased significantly across the 6-year period, generating three distinct learning curve phases: Learner phase (cases 1-23), Competence phase (24-73), and Mastery phase (74 and g...
As with many complex operations, there does appear to be a learning curve with OPS, as the operative time and the rates of partial nipple loss decreased over time....
To evaluate MWA efficacy and safety by cumulative MWA volume and interventional experience....
3113 primary liver cancers treated by 7 operators between 2006 and 2018 were studied. Conditional logistic regression was used to estimate within-operators effects of increasing cumulative MWA volume ...
Lower severe complication rate was detected only in higher MWA volume (HR: 0.31, P = 0.02)). TE rates increased with the increase of MWA volume ((100-150 procedures (HR: 0.33, P = 0.00); 150-200 proce...
Early and intensive performance of MWA procedures would reduce major complication rates regardless of tumor size and tumor location, but could not improve TE rate in high-risk locations....
While anterior cervical discectomy and fusion as well as cervical disk arthroplasty are gold standard treatments for the surgical treatment of cervical radiculopathy, posterior endoscopic cervical for...
The learning curve in operative time for two fellowship-trained spine surgeons at independent institutions was retrospectively assessed for 90 uniportal PECF procedures (PBD: n = 26, CPH: n = 64) perf...
There was no significant difference in operative time between surgeons (p = 0.420). The start of a plateau for Surgeon 1 occurred at 9 cases and 111.6 min. The start of a plateau for Surgeon 2 occurre...
PECF is an advanced endoscopic technique with an initial improvement in operative time that occurred after as few as 8 cases to as many as 28 cases in this series. A second learning curve may occur wi...
The most common surgical intervention in childhood is inguinal hernioplasty....
The aim of the authors was to evaluate the learning curve of PIRS (percutaneous internal ring suturing)....
A prospective observational cohort was studied including patients under the age of 18 years with planned PIRS between 2018 and 2019. Patients with urgent intervention (incarceration) or other surgical...
PIRS was performed in 126 patients (57 boys, 69 girls) with an average age of 4.6 years. The average surgical time was 26.5 min, in the case of experts it was reduced to 22.9 min. The surgeries were l...
PIRS is a good laparoscopic "teaching" procedure during the training, but the open procedure has still place in the treatment....
PIRS is a safe procedure in childhood and can be easily learned. It is an excellent method in basic laparoscopic training by use of which metachronous hernia can be recognized. Orv Hetil. 2023; 164(7)...
Training is essential for the safe and uncomplicated placement of hemodialysis catheters. This study explores the learning curve of this procedure....
In this prospective study, 60 patients who needed emergency hemodialysis without vascular access were included. All catheters were placed under ultrasound guidance. One nephrologist was included in ea...
The patients' mean age was 67.92 ± 14.23 years. The mean catheter insertion time of the senior nephrologist was significantly shorter than that of the junior. According to cumulative total analysis, t...
This study suggests that 22 catheter insertions under the supervision of a senior nephrologist are needed to complete the learning curve for a junior nephrologist. If the number of nephrologists at th...
The aim of this study was to examine the development of surgical skills among surgeons learning total laparoscopic hysterectomy (TLH), using differences in complication rates between surgeons with dif...
This retrospective, single-center cohort study included 576 total laparoscopic hysterectomy procedures conducted between January 2015 and December 2019 at the municipal hospital in Karlsruhe, Germany....
No differences in complication rates were seen between experienced and inexperienced surgeons. With growing numbers of procedures, most surgeons quickly became faster, leading to reduced operating tim...
Learning laparoscopic hysterectomy in routine practice is safe for patients, and surgeons rapidly become faster as growing numbers of procedures are performed. Operating times for experienced surgeons...
Prediction of proficiency of laparoscopic skills is essential to establish personalized training programs. Objective assessment of laparoscopic skills has been validated in a laparoscopic box trainer ...
Surgical residents in their first year of training performed six different tasks in the Lapron box trainer. Force, motion and time data, three objective measures of tissue manipulation and instrument ...
A total of 6010 practice sessions performed by 42 trainees from 13 Dutch hospitals were assessed and included for analysis. Proficiency level was determined as a mean result of seven experts performin...
The learning curve of proficiency of laparoscopic skills can accurately be predicted after three repetitions of six tasks in a training box with force, path length and time recognition. This will faci...
Varicocele occurs in 15% of general male population and in 35% of infertile men. Since 1992, surgical correction with laparoscopic varicocelectomy is the gold standard for treatment of symptomatic pat...
