INTRODUCTION: Basilar invagination can result from a variety of systemic diseases that can weaken the structural integrity of the craniocervical junction. Definitive treatment often requires ventral decompression along with posterior decompression and fusion. Endonasal odontoidectomy is a relatively new minimal access procedure, however, quality of life after this procedure has not been reported. METHODS: We reviewed a consecutive database of endonasal odontoidectomy patients and identified those having posterior decompression and fusion...

Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...

BACKGROUND: Stereotactic laser ablation (SLA), also termed laser interstitial thermal therapy (LITT), is a minimally invasive procedure that is increasingly utilized in neurosurgery. We wished to examine how/if SLA is changing the landscape of treatment options for neurosurgical patients. METHODS: Patients undergoing stereotactic laser ablation were prospectively enrolled in the Laser Ablation of Abnormal Neurological Tissue (LAANTERN) registry. Data from the first 100 enrolled patients are presented here...

Introduction: Primary hyperparathyroidism is one of the most common endocrine disorders requiring surgical parathyroidectomy for its definitive treatment. Surgical exploration is traditionally performed through conventional open neck approach. A wide range of minimal access and minimally invasive endoscopic techniques (gas less and with gas) have been attempted in the past two decades. In this context, we evaluated the feasibility and safety of an innovative transoral endoscopic parathyroidectomy (EP) technique, which represents a paradigm shift in transluminal endocrine surgery...

Introduction: Since the first description by William Ladd, the Ladd's procedure has been the surgery of choice for the correction of malrotation. The laparoscopic Ladd's procedure is becoming popular with the advent of minimal access surgery and is described in the literature. Various techniques of the Ladd's procedure have been described but none of them describes the stepwise technique for derotation of volvulus which is the most difficult and confusing part of the surgery. We describe 'steering wheel' technique for easy derotation of volvulus associated with malrotation...

BACKGROUND: Minimally invasive and remote access thyroid surgery has been evolving with the transoral endoscopic thyroidectomy vestibular approach (TOETVA) emerging as a true "scarless" thyroidectomy. In this study, we describe a hybrid transoral and submental thyroidectomy (TOaST) technique for thyroid lobectomy. MATERIALS AND METHODS: A TOaST right thyroid lobectomy was performed for a 4 cm cytologically benign right thyroid nodule. Initial incision was made in the submental region with two additional 5 mm lateral ports inserted transorally...

BACKGROUND: Minimally invasive surgical techniques (MISTs) could have tremendous benefits in resource-poor environment. There is growing interest in MISTs in most low- and middle-income countries (LMIC), but its adoption has remained limited; this is largely due to high cost of the initial setup, lack of technological backup and limited access to training among others. An affordable laparoscopic setup will go a long way in improving access to MISTs. METHODS: A common zero degrees 10 mm scope is attached on the camera of a low-price smartphone...

Minimally invasive aortic valve replacement has been used for more than 20 years, but its uptake has been limited. The volumes have increased steadily over the last 10 years, but it is still not regarded as a mainstream procedure. The issue, to some extent, is due to the lack of perceived evidence that minimal access incisions confer any benefit other than cosmetic appearance. In this article, the current literature on minimally invasive aortic valve replacement is reviewed, and it is concluded that benefits are demonstrable, particularly in higher risk, comorbid settings...

BACKGROUND: Endopancreatic surgery (EPS) is an experimental minimally invasive technique for resection of pancreatic tissue from inside the pancreatic duct, accessed via the duodenum and papilla. It is proposed as an alternative to duodenum-preserving pancreatic head resection in benign diseases such as chronic pancreatitis (CP). This study evaluated the use of EPS for resection of pancreatic duct stenoses. Moreover, greenlight laser (GLL) and monopolar electrosurgical device (MES) were compared as resection tools for EPS...

Interbody fusions are routinely used in deformity surgery to achieve both coronal and sagittal correction and attain increased fusion rates. Minimally invasive interbody techniques, including the prepsoas approach, are being utilized to decrease tissue disruption, blood loss, and patient morbidity with similar outcomes compared to traditional surgery. The prepsoas oblique lateral interbody fusion, accesses the spine between the iliac arteries or aorta and psoas muscle, and allows for exposure of the lumbar spine while avoiding some complications commonly seen with a direct lateral approach...

Background: Transforaminal lumbar endoscopic discectomy is a minimally invasive surgical procedure that can be performed in awake patients through an incision less than 1 cm. The procedure requires very little bony removal to access the herniated disc material because the approach is through the foramen, and only a small amount of the superior articulating process is removed to access Kambin's triangle. This study describes our experience with transforaminal endoscopic lumbar decompression (TELD) for the treatment of lumbar disc herniation...

INTRODUCTION: Endovascular aortic interventions are suitable alternatives to open surgery, being less invasive and having lower mortality and complications. Accurate positioning of the stent graft is a critical point because of systolic thrush. Techniques used to prevent it include pharmacological (antihypertensive drugs, nitroglycerin, adenosine) and mechanical methods (temporary caval occlusion by balloon). Rapid Right Ventricular Pacing (RRVP) is an emerging alternative with good patient tolerance and low level of complications...

INTRODUCTION: Prevalence of Abdominal Aortic Aneurysm (AAA) with concomitant malignancy rounds 3-13%. Considering only urological neoplasms the prevalence is around 3.6%. Survival at 5 years of bladder carcinoma without extravesical invasion (stage II) rounds 63%. Endovascular Aneurysm Repair (EVAR), due to its minimally invasive profile, is an option for treatment of AAA prior to urological surgery as it does not require laparotomy not conditioning the delay of oncologic surgery. METHODS: Male, 62 years old...

INTRODUCTION: Thoracic endovascular aortic aneurysm repair (TEVAR) is an established treatment for thoracic aortic disease in both the acute and elective setting, with such a widespread use that almost 50% of all thoracic aortic surgery in Europe is performed by these means. Nonetheless, the feasibility of TEVAR is determined by several anatomic factors, and the suitability of the proximal and distal landing zones remain one of the main limitations to its use. The advent of custom-made thoracic stent grafts widened the endovascular options in some challenging anatomies...

INTRODUCTION: Intravascular or catheter embolization of a foreign body, either by fracture or migration, is a rare condition, occurring in approximately 1%. This study is focused on the migration of catheters since they represent the majority of cases of embolization. We present one of the largest published series of removal of foreign bodies with endovascular techniques. The objective of the present study is to demonstrate the different locations where foreign bodies, in most cases catheters, can reach, the technique used to remove them and the affected population...

BACKGROUND: Renal cell carcinoma has a natural tendency to extend through the renal vein. When the thrombus reaches the vena cava, thrombectomy and the necessary reconstruction of the vena cava are typically performed by open pathway. Robot-assisted technology provides advantages for performing this complex technique, using a minimally invasive access. MATERIAL AND METHODS: We present the technique we employed in the first case performed in our department. After performing renal artery embolisation, we conducted the surgery with the Vinci S robotic system...

Pan Li, Zhiyong Yang, Shan Jiang
Image-guided robot-assisted minimally invasive surgery is an important medicine procedure used for biopsy or local target therapy. In order to reach the target region not accessible using traditional techniques, long and thin flexible needles are inserted into the soft tissue which has large deformation and nonlinear characteristics. However, the detection results and therapeutic effect are directly influenced by the targeting accuracy of needle steering. For this reason, the needle-tissue interactive mechanism, path planning, and steering control are investigated in this review by searching literatures in the last 10 years, which results in a comprehensive overview of the existing techniques with the main accomplishments, limitations, and recommendations...

BACKGROUND: Hip arthroscopic treatment is not equally beneficial for every patient undergoing this procedure. Therefore, the purpose of this study was to develop a clinical prediction model for functional outcome after surgery based on preoperative factors. METHODS: Prospective data was collected on a cohort of 205 patients having undergone hip arthroscopy between 2011 and 2015. Demographic and clinical variables and patient reported outcome (PRO) scores were collected, and considered as potential predictors...
