Abstract Introduction and hypothesis In addition to laparoscopic sacrocolpopexy (LS), laparoscopic pectopexy (LP) is a novel surgical method for correcting apical prolapse. The descended cervix or vaginal vault is suspended with a synthetic mesh by fixing the bilateral mesh ends to the pectineal ligaments. This study was aimed at developing a learning curve for LP and to compare it with results with LS. Methods We started laparoscopic/robotic pectopexy in our department in August 2019. This retrospective study included the initial 18 consecutive women with apical prolapse receiving LP and another group undergoing LS (21 cases) performed by the same surgeon. The medical and video records were reviewed. Results The age was older in the LP group than in the LS group (65.2 vs 53.1 years). The operation time of LP group was significantly shorter than that of the LS group (182.9 ± 27.2 vs 256.2 ± 45.5 min, p < 0.001). The turning point of the LP learning curve was observed at the 12th case. No major complications such as bladder, ureteral, bowel injury or uncontrolled bleeding occurred in either group. Postoperative low back pain and defecation symptoms occurred exclusively in the LS group. During the follow-up period (mean 7.2 months in LP, 16.2 months in LS), none of the cases had recurrent apical prolapse. Conclusions Laparoscopic pectopexy is a feasible surgical method for apical prolapse, with a shorter operation time and less postoperative discomfort than LS. LP may overcome the steep learning curve of LS because the surgical field of LP is limited to the anterior pelvis and avoids encountering the critical organs.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.

Introduction. Anterior and apical prolapse is the most common type of pelvic organ prolapse. The insufficient  effectiveness of native tissue repair in the pelvic organs leads to the search of new methods of the pelvic floor reconstruction. Objective. The current analysis was undertaken to evaluate the efficiency of the use of the Pelvix anterior mesh system (Lintex) with sacrospinous fixation of the apex in the treatment of anterior and apical prolapse. Methods. This study involved 150 women suffering from anterior-apical prolapse (stages III and IV). Reconstruction with the use of the mesh was performed in all the patients. To evaluate the results of surgical treatment, data of a vaginal examination (POP-Q), uroflowmetry, bladder ultrasound, and validated questionnaires (PFDI-20, PFIQ-7, PISQ-12) were used. All the listed parameters were determined before the surgery and on follow-up visits in 1, 6, 12, and 24 months after the treatment. Results. Mean operation time was 47 minutes. No cases of intraoperative clinically significant bleeding were reported. Anatomical cure rate (< stage II / asymptomatic stage II, according to the Baden-Walker system) at 12 months was found to be 94.4%, and at 24 months — 92.7%. Within the first month of follow-up, de novo stress urinary incontinence and de novo urgency occurred in 8.0% and 7.2% of patients, respectively. Statistically significant (p < 0.05) improvement in uroflowmetry parameters and decreased post-voiding urine volume were achieved after the surgery and did not change by 24 months. Comparison of the scores by the questionnaires revealed a significant improvement in the quality of life in the postoperative period. Conclusion. The use of the Pelvix anterior mesh system in the surgical correction of the anterior and apical prolapse is a safe uterus-sparing technique. At two-year follow-up, it provides a high anatomical efficiency, normalizes urodynamic parameters and improves quality of life.

Physiopathological bases of cryosurgical damage are described: hypothermia, freezing, thawing are all disruptive moments causing necrosis. Last-generation cryosurgical apparatus allows the use of liquid nitrogen circulating through thin probes that are inserted percutaneously under u.s. guidance. Also thermosensors are used to monitor the procedure placing them in selected spots. 404 patients were treated in 3 different but homogeneous groups. Results of control biopsies were available at 3 months for 298 (15 pos.) and for 141 at 12 months (13 pos.). Cryoablation appears to be an interesting procedure, but its complexity requires accurate training with a steep “learning curve”; only long-term follow-up will test in the future its real efficacy.

A common assertion regarding the trajectory of surgeons from training to independent practice is that the first five years after completing training encompass the steepest learning curve of a young surgeon’s career. That assertion is often made in the context of beginning to perform operations independently.  However, it is likely that an under-recognized but equally steep learning curve will occur as newly minted surgeons begin to run their own clinics. In fact, it is likely that there is no aspect of surgical training with a greater discrepancy between the educational value for and the interest by surgical trainees than preoperative, postoperative, and follow-up clinics for surgical patients.

Abstract Women who underwent vaginal pelvic reconstructive surgery with or without mesh consecutively between 2004 and 2018 were retrospectively analyzed to determine the learning curve in vaginal pelvic reconstructive surgery. With cumulative summation (CUSUM) analysis of surgical failure and operation time, we assessed the learning curve of vaginal pelvic reconstructive surgery, including sacrospinous ligament fixation, anterior colporrhaphy, posterior colporrhaphy, and optional vaginal hysterectomy with or without mesh placement. Two hundred and sixty-four women with stage III or IV pelvic organ prolapse underwent vaginal pelvic reconstructive surgery by surgeon A or B. The median follow-up time of 44 months ranged from 24 to 120 months. Surgical proficiency was achieved in 32-54 vaginal pelvic reconstructive surgery procedures without mesh and 37-61 procedures in the same surgery with mesh. The surgical success rates for surgeons A and B were 82.2% and 94.1%, with median follow-up times of 60 and 33 months, respectively. The learning phase of vaginal pelvic reconstructive surgery in advanced pelvic organ prolapse in this institutional cohort required 54 and 61 procedures, respectively. A higher number of procedures were required for the learning curve of vaginal pelvic reconstructive surgery with mesh. Having crossed the boundary of proficiency, the surgical success rate and operation time were improved.

AbstractBackgroundNasal deformity associated with cleft lip deformity is a challenging issue, encompassing controversies, theories, and a diversity of techniques. Historically, esthetic outcomes have ranged from being below expectations to barely acceptable.MethodBased on the concept that the nasal cartilaginous framework in clefts is similar to that of a collapsing pyramid, a novel suspension technique has been described. The entire cartilaginous structure is lifted from the infratip segment with a loop suture and is secured in a cantilever fashion onto the periosteum overlying the nasal bone. This part of the operation is performed in a semiclosed manner. The technique is applied during primary surgery in bilateral and unilateral nasal cleft lip deformities, with changes in the orientation of the cantilever loop suture. Studies conducted by Masters S. Tajima, H. McComb, H. Thomson, D. Fisher, and J. Mulliken, which are most relevant to this article, have been reviewed and discussed throughout.ResultsThe technique was first applied over 10 years ago. A case series of nine children whose parents consented to the developing technique is presented with follow-up ranging from months to years, along with technical descriptions and illustrative drawings. None of these cases had preoperative orthopedic correction, molding, or postoperative nostril splints. The esthetic outcome was optimal enough; none of the cases requested a secondary correction.ConclusionThe nasal cantilever technique is a novel concept in cleft nasal deformity, which can be used in conjunction with an appropriate lip technique, per the surgeon’s discretion. Other than a learning curve, we believe that it provides a solid correction by securing the cartilaginous structures after they have been mobilized to a stable base, the nasion.
