Abstract Purpose: To describe a novel surgical technique for iridodialysis repair using iris retractor segments and report its clinical results.Methods: 53 eyes of 53 patients who underwent surgery for iridodialysis repair were enrolled in this retrospective study. Data recorded from patient files consisted of age, sex, history of trauma, surgical indications and type of surgery, preoperative and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), complications, and follow-up time. The novel, minimally invasive surgical technique was explicitly described in detail.Results: Mean follow-up time was 34.4 (range 12-84) months. The subjects were 29 (54.7%) men and 26 (45.3%) women, and the mean age was 56.6±14.0 years. Iridodialysis repair performed using one segment in 37 (69.8%) eyes, two segments in 15 (28.3%) eyes, and three segments in 1 (1.9%) eye. Pupilloplasty was performed in 17 eyes due to wide pupil diameter. The iridodialysis repair was combined with lens removal in 48 eyes, and anterior vitrectomy was performed in 10 eyes. CDVA significantly improved after surgery (p<0.001). Post-traumatic IOP rise was the most common complication, and six patients needed medical therapy for glaucoma control.Conclusion: Iridodialysis repair using iris retractor segment is a minimally invasive technique and found to be safe and effective, providing less surgical manipulation and surgical time than other techniques.

This article describes a minimally invasive surgical technique for implanting the pacemaker with a microelectromechanical system (MEMS) converter of kinematic energy into electrical energy in patients with life-threatening rhythm disorders. This kind of technique is recommended for patients with cardiac pathology who are preparing for surgical treatment of the main pathology with simultaneous implantation of the pacemaker with MEMS-converter of kinematic energy into electrical energy. Implantation of the pacemaker should be performed in the most energy-efficient zone of the epicardium, determined in advance by the method of tissue echocardiography.

Object Thoracic disc herniations can be surgically treated with a number of different techniques and approaches. However, surgical outcomes comparing the various techniques are rarely reported in the literature. The authors describe a minimally invasive technique to approach thoracic disc herniations via a transpedicular route with the use of tubular retractors and microscope visualization. This technique provides a safe method to identify the thoracic disc space and perform a decompression with minimal paraspinal soft tissue disruption. The authors compare the results of this approach with clinical results after open transpedicular discectomy. Methods The authors performed a retrospective cohort study comparing results in 11 patients with symptomatic thoracic disc herniations treated with either open posterolateral (4 patients) or mini-open transpedicular discectomy (7 patients). Hospital stay, blood loss, modified Prolo score, and Frankel score were used as outcome variables. Results Patients who underwent mini-open transpedicular discectomy had less blood loss and showed greater improvement in modified Prolo scores (p = 0.024 and p = 0.05, respectively) than those who underwent open transpedicular discectomy at the time of early follow-up within 1 year of surgery. However, at an average of 18 months of follow-up, the Prolo score difference between the 2 surgical groups was not statistically significant. There were no major or minor surgical complications in the patients who received the minimally invasive technique. Conclusions The mini-open transpedicular discectomy for thoracic disc herniations results in better modified Prolo scores at early postoperative intervals and less blood loss during surgery than open posterolateral discectomy. The authors' technique is described in detail and an intraoperative video is provided.

The present study was planned to evaluate minimally invasive tube cystotomy technique in calves suffering from obstructive urolithiasis having intact urinary bladder and urethra. Fifteen male non-castrated calves with age ranging from 1-10 months (mean 4.05 months), presented for treatment within one to three days (mean 2.2 days) of complete urinary tract obstruction due to urethral calculi with intact bladder and urethra, were included in this study. Under light sedation and local infiltration anaesthesia, all the animals were subjected through left paralumbar fossa, to a minimally invasive surgical tube cystotomy in which catheter was placed in the bladder lumen through a metallic cannula and fixed to the skin with a stay suture (Fazili’s technique). All the animals were discharged the same day. Time taken for the procedure varied from 8 to 17 minutes (mean 11.0 minutes). Normal urination resumed in twelve (80.0%) calves. Mean time taken for normal urination was 10.50 days. In two of the remaining calves, urine flow stopped through the catheter prematurely and they were then subjected to standard surgical tube cystotomy. One more calf did not urinate normally for 30 postoperative days and was lost to the follow up thereafter. Recurrence of the obstruction was not detected in ten and nine animals observed up to six and 12 months respectively. In conclusion, the outcome of this minimally invasive technique is similar to the standard tube cystectomy. Additionally, the procedure is cost effective, quick, simple and field applicable. It also minimizes exposure of abdominal cavity of metabolically compromised animals. However, the technique needs to be tried in larger number of such calves wherein better quality catheter of larger diameter be used before recommending its extensive use.

Abstract Background Lumbar interbody fusion is a standard technique for treating degenerative lumbar disorders involving instability. Due to its invasiveness, a minimally invasive technique, extraforaminal lumbar interbody fusion (ELIF), was introduced. On surgically approaching posterolaterally, the posterior muscles and spinal canal are barely invaded. Despite its theoretical advantage, ELIF is technically demanding and has not been popularised. Therefore, we developed a microendoscopy-assisted ELIF (mELIF) technique which was designed to be safe and less invasive. Here, we aimed to report on the surgical technique and clinical results. Methods Using a posterolateral approach similar to that of lateral disc herniation surgery, a tubular retractor, 16 or 18 mm in diameter, was placed at the lateral aspect of the facet joint. The facet joint was partially excised, and the disc space was cleaned. A cage and local bone graft were inserted into the disc space. All disc-related procedures were performed under microendoscopy. The spinal canal was not invaded. Bilateral percutaneous screw-rod constructs were inserted and fixed. Results Fifty-five patients underwent the procedure. The Oswestry Disability Index and visual analogue scale scores greatly improved. Over 90% of the patients obtained excellent or good results based on Macnab’s criteria. There were neither major adverse clinical effects nor the need for additional surgery. Conclusions mELIF is minimally invasive because the spinal canal and posterior muscles are barely invaded. It produces good clinical results with fewer complications. This technique can be applied in most single-level spondylodesis cases, including those involving L5/S1 disorders.

Abstract Introduction The accepted treatment of pilonidal disease still consists of surgical excision with primary wound closure. This treatment has complications such as excessive pain, delayed wound healing, and recurrence. We introduced this technique using a radial laser probe (SiLaCTM, Biolitec, Germany). Previous studies have shown encouraging results with respect to safety, patient satisfaction, and minimal recurrence rates. Method The pilot project was planned with the objectives to assess postoperative complications and reoperation rates. All operations were performed as day case procedures under general anaesthesia. We studied the data of our first 25patients operated with this technique between January 2019 and December 2019 using a prospective database and outpatient clinic follow up. Results The median follow up duration was 13 months. The initial success rate was 64%(16/25), reoperation was required in 32%(8/25) and one patient was lost to follow up. one patient returned with abscess formation in the postoperative period. Conclusions SiLaC is a safe and minimally invasive technique for the destruction of the pilonidal cyst and sinus. The success rate is modest, making this new therapy a minimally invasive option for the majority of the patients with pilonidal disease but it should be offered with caution.

Purpose. To compare the functional and clinical outcomes of the iris-claw intraocular lens (IOL) placed on the anterior versus posterior surface of the iris. Patients and Methods. A multicenter, retrospective study. Data on eyes that underwent anterior or retropupillary iris-claw IOL implantation because of inadequate capsular support secondary to complicated cataract surgery, trauma, and dislocated/opacified IOLs since January 2015 were analyzed. For study inclusion, evaluation results had to be available in the medical records both preoperatively and at 1 and 12 months after implantation. The following parameters were compared between the groups: best-corrected distance visual acuity (BCDVA), spherical and cylindrical refractive error, endothelial cell density (ECD), central macular thickness (CMT), and percentage and type of postoperative complications. Results. In total, 60 eyes of 60 patients aged 73 ± 13 years were included: 28 eyes (47%) involved anterior, and 32 eyes (53%) retropupillary, iris-claw IOL fixations. Preoperatively, the groups were similar in all parameters except for a significantly higher proportion of retropupillary fixations in patients who had previously experienced a closed-globe trauma (p=0.03). The groups showed comparable improvements in BCDVA after surgery (final BCDVA: 0.34 ± 0.45 vs. 0.37 ± 0.50 logMAR in the anterior and retropupillary placement groups, respectively). During follow-up, no group difference was observed in refractive error or CMT. Both groups experienced similarly marked ECD loss and showed similar incidence of postoperative complications, with cystoid macular edema being the most common complication. Multivariable linear regression showed that BCDVA at 1 month was the best predictor of the final BCDVA. Conclusions. Anterior chamber and posterior chamber iris-claw IOL fixations proved equally effective and safe for aphakic correction in eyes with inadequate capsular support.

Sialendoscopy has emerged as a safe, effective and minimally invasive technique for management of obstructive and inflammatory salivary gland disease. The aim of our study was to analyze outcomes of sialendoscopy and steroid irrigation in patients with sialadenitis without sialoliths. We performed a retrospective analysis of patients who underwent interventional sialendoscopy with steroid irrigation from 2013 to 2016, for the treatment of sialadenitis without sialolithiasis. Twenty-two patients underwent interventional sialendoscopy with ductal dilation and steroid irrigation for the treatment of sialadenitis without any evidence of sialolithiasis. Conservative measures had failed in all. Eleven patients had symptoms arising from the parotid gland, 4 patients had symptoms arising from the submandibular gland, while 6 patients had symptoms in both parotid and submandibular glands. One patient complained of only xerostomia without glandular symptoms. The mean age of the study group which included 1 male and 21 females was 44.6 years (range: 3-86 years). Four patients had autoimmune disease, while 7 patients had a history of radioactive iodine therapy. No identifiable cause for sialadenitis was found in the remaining 11 patients. The mean follow-up period was 378.9 days (range: 16-1143 days). All patients underwent sialendoscopy with ductal dilation and steroid irrigation. Twelve patients showed a complete response and 9 patients had a partial response, while 1 patient reported no response. Only 3 patients required repeat sialendoscopy. The combination of sialendoscopy with ductal dilation and steroid irrigation is a safe and effective treatment option for patients with sialadenitis without sialoliths refractory to conservative measures. Prospective studies with a larger case series are needed to establish its role as a definitive treatment option.
