Virtual reality system for planning minimally invasive neurosurgery

2008

Object The authors report on their experience with a 3D virtual reality system for planning minimally invasive neurosurgical procedures. Methods Between October 2002 and April 2006, the authors used the Dextroscope (Volume Interactions, Ltd.) to plan neurosurgical procedures in 106 patients, including 100 with intracranial and 6 with spinal lesions. The planning was performed 1 to 3 days preoperatively, and in 12 cases, 3D prints of the planning procedure were taken into the operating room. A questionnaire was completed by the neurosurgeon after the planning procedure. Results After a short period of acclimatization, the system proved easy to operate and is currently used routinely for pre…

How to select early-stage cervical cancer patients still suitable for laparoscopic radical hysterectomy: a propensity-matched study

2020

Background: Recently, it was reported that minimally invasive surgery (MIS) has a negative impact on early-stage cervical cancer (ECC) patient survival. At the same time, advantages of MIS regarding quality of life and low rate of intra- and postoperative complications are well known. Therefore, it is essential to select patients who may benefit from MIS without worsening their oncologic outcomes. The aim of this study is to investigate which pathological factors could guide surgeons’ choice about the best approach in ECC. Patients and Methods: Patients with 2009 FIGO stage from IA1 with lymphovascular space invasion (LVSI) to IB1/IIA1 treated by open or laparoscopic surgery were judged eli…

The minimally invasive supraorbital subfrontal key-hole approach for surgical treatment of temporomesial lesions of the dominant hemisphere

2009

INTRODUCTION: Surgery in the temporomesial region is generally performed using a subtemporal, transtemporal, or pterional-transsylvian approach. However, these approaches may lead to approach-related trauma of the temporal lobe and frontotemporal operculum with subsequent postoperative neurological deficits. Iatrogenic traumatisation is especially significant if surgery is performed in the dominant hemisphere. METHODS: During a five-year period between January 2003 and December 2007, we have approached the temporomesial region in 21 cases via the supraorbital approach. In 15 cases, the lesion was located within the dominant hemisphere, all lesions had space-occupying effects. In all cases, …

The supraorbital endoscopic approach for aneurysms.

2013

Objective To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of intracranial aneurysms, using the supraorbital keyhole craniotomy. Methods The supraorbital keyhole approach was performed through an eyebrow skin incision in 793 cases for treatment of 989 intracranial aneurysms. Of patients, 474 were operated on after subarachnoid hemorrhage, and 319 were operated on under elective conditions. After lateral frontobasal burr hole trephination, a limited subfrontal craniotomy was created. To achieve adequate intraoperative exposure through the limited approach, endoscopes were used routinely. Surgical outcome was assessed using the mo…

Intraocular pressure after small incision cataract surgery: temporal sclerocorneal versus clear corneal incision.

2001

To compare intraocular pressure (IOP) after phacoemulsification and foldable intraocular lens (IOL) implantation using a temporal sclerocorneal or clear corneal incision.Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany.One hundred patients (100 eyes) with cataract having phacoemulsification with posterior chamber IOL implantation were randomly assigned to receive a temporal sclerocorneal or clear corneal tunnel incision. Intraocular pressure was measured preoperatively and 6 hours, 1, 2, and 3 days, and 5 months postoperatively. Statistical significance was determined by nonparametric group comparisons using 2-sample random Wilcoxon tests.Six hours postoperatively,…

Short-Term Functional and Oncologic Outcomes of Nephron-Sparing Surgery for Renal Tumours ≥7cm

2011

Abstract Background Nephron-sparing surgery (NSS) for renal tumours preserves renal function and has become the standard approach for small renal tumours. Little is known about perioperative and oncologic outcomes of patients following NSS in renal tumours ≥7cm in the presence of a healthy contralateral kidney. Objective To analyse oncologic outcomes and perioperative morbidity in patients treated by NSS for renal tumours ≥7cm. Design, setting, and participants In total, 5767 patients were treated for renal tumours at two institutions from 1984 to 2009. In 91 patients, elective NSS was performed for renal tumours ≥7cm. Measurements Complication rates were assessed in detail and stratified u…

Minimally invasive video-assisted thyroidectomy: four-year experience of a single team in a General Surgery Unit.

2013

Minimally invasive video-assisted thyroidectomy (MIVAT) is a surgical technique that has showed increasingly good results, particularly in endocrine surgery centers. The aim of this prospective, non-randomized study was to evaluate feasibility, advantages and critical aspects of MIVAT in a general surgery unit.Two hundred twenty-four patients underwent total thyroidectomy for benign thyroid disease from May, 2008 to April, 2011. They were divided into two groups: one underwent conventional thyroidectomy (CT), and the other underwent MIVAT. The inclusion criteria were thyroid volume ≤35 mL and main nodule size ≤35 mm. For each patient, socio-demographic variables, hospitalization data and ou…

Minilaparoscopy-guided spleen biopsy in systemic disease with splenomegaly of unknown origin.

2002

With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with systemic disease of unknown origin and splenomegaly, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear systemic disease were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode …

Hand-assisted laparoscopic living-donor nephrectomy versus open surgery: evaluation of surgical trauma and late graft function in 82 patients

2009

Abstract Objective We evaluated and quantified surgical trauma and late graft function in cases of hand-assisted laparoscopic living-donor nephrectomy (HALLDN) versus open living-donor nephrectom (OLDN). Methods This study is a retrospective nonrandomized single-center analysis. Between 1995 and January 2008, 82 patients with end-stage renal disease received kidney transplantations from living donors. Open living-donor nephrectomy was performed in 37 donors, and 45 underwent laparoscopic hand-assisted nephrectomy. Demographic data and perioperative and postoperative data, such as markers of acute phase (C-reactive protein; serum amyloid A) and biochemical markers of glomerular filtration (s…
