The endoscopic hemi-transseptal approach to the sella turcica: operative technique and case-control study.

ABSTRACT: Background The hemi-transeptal (Hemi-T) approach was developed to facilitate a binasal two-surgeon endoscopic approach for sellar tumors, with preservation of the nasoseptal flap and selective mobilization for reconstruction. Methods A retrospective case-control study was performed comparing the Hemi-T approach with previously used methods of sellar exposure and reconstruction. Outcome measures included operative time and postoperative nasal morbidity. Results A total of 23 patients underwent the Hemi-T approach versus 42 in whom traditional exposure was performed. Operative time was significantly shorter using the Hemi-T technique (152.6 ± 56.8 versus 205.2 ± 61.3 minutes; p = 0.001), as was the length of hospital stay (3.3 ± 1.9 versus 5.4 ± 3.6 days; p = 0.004). There was no difference in the rates of intraoperative or postoperative cerebrospinal fluid leak, cartilage necrosis, septal perforation, or mucosal adhesions. Conclusion The Hemi-T approach facilitates binasal two-surgeon access to the sella without compromise of the pedicle during the extended sphenoidotomies and tumor removal. Operative time and nasal morbidity is not increased, and iatrogenic injury to the nasal cavity is minimized when a flap is not required.

APACHE-Anterior Plating of the Acetabulum in Hemi-Endoscopic Technique: An Alternative Method for Internal Fixation of the Acetabulum.

Project description:Injuries of the acetabulum are often challenging in treatment and aftercare. One reason is the required surgical approach, which has high complication rates, including vascular lesion, hernias, and wound infection. We present an alternative endoscopic-assisted approach for the internal fixation of acetabular fractures to avoid the Pfannenstiel incision. An endoscopic approach similar to that used for endoscopic hernia surgery was used. The ilioinguinal approach's lateral window was used to achieve reduction and insertion of a reconstruction plate. The purpose of this study is to describe a minimally invasive technique as a possible method to reduce hospitalization and complications. Another goal is to give detailed technical recommendations and to assess the potential pitfalls of this surgical approach. The APACHE technique is a safe and suitable minimally-invasive approach for the successful treatment of complex acetabular fractures and can be considered in similar cases.

Effects of endoscopic sphincterotomy on biliary epithelium: a case-control study.

Project description:To study the long-term effects of endoscopic sphincterotomy on biliary epithelium.This is a prospective case-control study. A total of 25 patients with a median age of 71 years (range 49-89 years) and prior endoscopic sphincterotomy (ES) for benign disease formed the first group. The median time from ES was 42 mo (range 8-144 mo). Another 25 patients with a median age of 76 years (range 44-94 mo) and similar characteristics who underwent current endoscopic retrograde cholangiopancreatography (ERCP) and ES for benign disease formed the second group (control group). Brush cytology of the biliary tree with p53 immunocytology was performed in all patients of both groups. ERCPs and recruitment were conducted at the Endoscopic Unit of Aretaieion University Hospital and Tzaneio Hospital, Athens, from October 2006 to June 2010.No cases were positive or suspicious for malignancy. Epithelial atypia was higher in the first group (32% vs. 8% in the second group, P = 0.034). Acute cholangitis and previous biliary operation rates were also higher in the first group (acute cholangitis, 60% vs. 24% in the second group, P = 0.01; previous biliary operation, 76% vs. 24% in the second group, P = 0.001). Subgroup analysis showed that previous ES was the main causal factor for atypia, which was not related to the time interval from the ES (P = 0.407). Two patients (8%) with atypia in the first group were p53-positive.ES causes biliary epithelial atypia that represents mostly reactive/proliferative rather than premalignant changes. The role of p53 immunoreactivity in biliary atypia needs to be further studied.

Endoscopic transorbital extradural anterior clinoidectomy: A stepwise surgical technique and case series study [SevEN-013].

Project description:BackgroundAnterior clinoidectomy is an important procedure for approaching the central skull base lesions. However, anterior clinoidectomy through the endoscopic transorbital approach (ETOA) still has limitations due to technical difficulties and the structural complexity of the anterior clinoid process (ACP). Therefore, the authors designed a stepwise surgical technique of extradural anterior clinoidectomy through the ETOA. The purpose of this study was to evaluate the feasibility of this technique.MethodsAnatomical dissections were performed in 6 cadaveric specimens using a neuroendoscope and neuro-navigation system. The extradural anterior clinoidectomy through the ETOA was performed stepwise, and based on the results, this surgical technique was performed in the 7 clinical cases to evaluate its safety and efficiency.ResultsEndoscopic extradural anterior clinoidectomy was successfully performed in all cadaveric specimens and patients using the proposed technique. This 5-step technique enabled detachment of the lesser wing of sphenoid bone from the ACP, safe unroofing of the optic canal, and resection of the optic strut without injuring the optic nerve and internal carotid artery. Since the sequential resection of the 3 supporting roots of the ACP was accomplished safely, anterior clinoidectomy was then successfully performed in all clinical cases. Furthermore, no complications related to the anterior clinoidectomy occurred in any clinical case.ConclusionWe designed a stepwise surgical technique that allows safe and efficient anterior clinoidectomy through the ETOA. Using this technique, extradural anterior clinoidectomy can be accomplished under direct endoscopic visualization with low morbidity. Since this technique is applicable to the central skull base surgery where anterior clinoidectomy is necessary, it expands the application of the ETOA.

Trans-oral endoscopic endocrine surgery vestibular approach: Pioneering the technique in the Gulf Cooperation Council Countries - A case series.

Project description:Background:We present our experience with the first five thyroidectomies and parathyroidectomy in Kuwait performed via the transoral endoscopic vestibular approach. Methods:Retrospective data collection for all trans-oral endoscopic vestibular approach endocrine surgeries performed at a single institution in Kuwait between November 2019 and February 2021. Information on patient demographics, perioperative management and complications were collected and reviewed. Outcomes:All 5 cases were completed successfully; the intended specimen was extracted successfully via the trans-oral endoscopic vestibular approach and conversion to traditional trans-cervical approach (TCA) was not required. Operative time for the parathyroidectomy case was 225 min and the average operative time for the remaining 4 cases, thyroidectomies, was 151 min. Blood loss was minimal, and length of hospital stay was between 24 and 48 h. One patient had a transient mental nerve injury, and one patient experienced a postoperative seroma which required aspiration. One case required completion thyroidectomy as histopathology revealed papillary thyroid carcinoma. Conclusion:Transoral vestibular approach is a scar free and safe approach to thyroidectomies and parathyroidectomies. Careful patient selection and counselling with regards to risk versus benefit is required. It is an excellent alternative to the traditional transcervical approach and offers great cosmetic results.

Endoscopic Septoplasty-Two Handed Technique with Endoscope Holder: A Novel Approach.

Project description:The popularity of endoscopes has been expanding not only in diagnostics but also in therapeutics. The traditional septal surgery also has come under the purview of endoscopic surgery in the last few decades. Endoscopic septoplasty has definitely many advantages over the conventional procedure. But the only disadvantage of endoscopic surgery is that it is a single handed technique as the other hand is used for holding the endoscope which may compromise the overall surgical time as the hemostasis and suctioning of the surgical field off the blood cannot be done simultaneously, in addition to the surgeon fatigue associated with holding the endoscope in the left hand. Endoscope holder allows both hands of the surgeon to be free for surgical manipulation and also imitates more or less same actions of the left hand. To report the preliminary use of Khan's endoscope holder for endoscopic septoplasty. Prospective Non Randomized Clinical Study. Khan's Endoscope Holder, which was primarily designed for endoscopic ear surgery, has been used for two handed technique of endoscopic septoplasty. The design of the Endoscope holder is described in detail. A total of 49 endoholder assisted endoscopic septoplasties were operated from Nov 2014 to Jan 2015 in MIMER Medical College and Sushrut ENT Hospital, Talegaon D, Pune, India. Our Endoscope Holder is a good option for two handed technique in Endoscopic Septoplasty due to its advantages. The study reports the successful usage and applicability of the endo holder for endoscopic Septoplasty. Level of evidence IV.

Bi-nostril transseptal endoscopic approach to the sphenoidal gate. A new technique.

Project description:BackgroundThere are multiple approaches to reach the sellar region using microscope or endoscope, which are the old sublabial, with its post-operative morbidities, or the uni-nostril transseptal, which has a limited working field. Another technique is the direct transnasal, which is associated with tissue sacrifice, and lastly the bi-nostril (one side transseptal-other side transnasal), aiming to preserve one of the septal flaps.MethodWe have 27 case studies using a new technique in which we access the sphenoid endoscopicaly through the nasal septum from both nostrils under the mucoperichondrial-periosteal flap.ConclusionThis new technique provides easy way of wide exposure to the sphenoidal gate, with easier closure of the operative field.
