Jun-Ichiro Nakamura, Kiyoshi Yoshihara
BACKGROUND: Percutaneous full-endoscopic discectomy (PED) is being increasingly used because of its potential to minimalize soft-tissue damage and decrease hospital stay. PED using the interlaminar approach (PED-IL) at L4-L5 is performed by only a few surgeons. To the best of our knowledge, the safety and efficacy of PED-IL at L4-L5, without experience in PED via a transforaminal approach (PED-TF) has not been previously reported. OBJECTIVE: This study aimed to evaluate initial clinical outcomes and complications of PED-IL at L4-L5 without experience in PED-TF...

Gastric volvulus (GV) is characterized by the abnormal rotation of a portion of the stomach around a horizontal or vertical axis that can cause obstruction, vascular disorder and even strangulation, and may evolve into necrosis or even perforation. It can be classified according to its aetiology into primary or secondary GV, according to its anatomy into axial organ or into axial mesenteric GV, and according to its presentation into chronic or acute GV. Both types of volvulus require treatment; however, in spite of the classic treatment being open surgery, there is no standard treatment, nor is there consensus on the alternative of choice at present...

REVIEW
Wayland J Wu, Zeph Okeke
Percutaneous nephrolithotomy has become the preferred treatment modality for patients with large renal calculi. The technique provides excellent stone clearance, but complication rates are higher than those of minimally invasive techniques, such as ureteroscopy and shockwave lithotripsy. Guy's stone score, S.T.O.N.E. nephrolithometry, the CROES nomogram, and S-ReSC are contemporary scoring systems introduced to provide standardized grading of stone complexity and outcomes of percutaneous stone surgery. Guy's stone score is easy to apply and has been validated in multiple studies...

Laparoscopy has become the standard surgery mode of right hemicolectomy, including conventional laparoscopy, hand-assisted laparoscopic surgery (HALS), single-port laparoscopic surgery (SPLS), natural orifices translumenal endoscopic surgery (NOTES) and robotic laparoscopy. How to select reasonable laparoscopic mode could be confusing sometimes. For patients, safety, cost-effectiveness and radical cure of the surgery are very important. For doctors, advance and convenience of the surgery must be considered as well...

PURPOSE: In endoscopic surgery such as video-assisted thoracoscopic surgery and laparoscopic surgery, providing the surgeon a good view of the target is important. Rigid endoscope has for years been the go-to tool for this purpose, but it has certain limitations like the inability to work around obstacles. To improve on current tools, a novel multi-articulated endoscope (MAE) is currently under development. To investigate its feasibility and possible value, we performed a user test using virtual prototype of the MAE with the intent to show that it outperforms the conventional endoscope while bringing minimal additional burden to the operator...

BACKGROUND: In recent years, laparoscopic sleeve gastrectomy (LSG) has become more acceptable for obese patients. Single-port sleeve gastrectomy (SPSG) is more popular since each abdominal incision carries the risk of bleeding, hernia, and internal organ injury as well as exponentially affecting cosmesis. This cross-sectional study aimed at comparing multi-port sleeve gastrectomy (MPSG) and SPSG in terms of their early results and complications. METHODS: Out of129 obese patients candidated for LSG, 102 patients were assigned to 2 groups of SPSG and MPSG...

Three-dimensional (3D) visualization of preoperative and intraoperative medical information becomes more and more important in minimally invasive surgery. We develop a 3D interactive surgical visualization system using mobile spatial information acquisition and autostereoscopic display for surgeons to observe surgical target intuitively. The spatial information of regions of interest (ROIs) is captured by the mobile device and transferred to a server for further image processing. Triangular patches of intraoperative data with texture are calculated with a dimension-reduced triangulation algorithm and a projection-weighted mapping algorithm...

Retroperitoneal fibrosis is a disease that may condition a severe involvement of various organs, mainly upper urinary tract, even causing renal insufficiency. It was first described by Albarran in 1905 and it is also known as Ormonds disease. The correct diagnosis includes, in many cases, the performance of one or more tests: CT scan, MRI, renal scan, etc. It is often necessary the insertion of double J catheters on percutaneous nephrostomy tubes with the aim to preserve renal function. Initial treatment is medical, based on corticoids, and , less frequent, immunosuppressive or chemotherapy drugs...

OBJECTIVE: Renal transplant surgery has not undergone any major changes until a few years ago, probably due to the technical difficulty involved in performing a laparoscopic transplant. With the introduction of robotic technology, the difficulties derived from laparoscopic surgery in certain procedures have been reduced, so we can now offer a minimally invasive approach to kidney recipients. METHODS: Review of published literature on robotic kidney transplantation...

OBJECTIVES: Uretero-pelvic junction (UPJ) obstruction has been classically treated by open dismembered pyeloplasty. Recently, laparoscopic (LP) and robotic pyeloplasty (RP) have become the techniques of choice for the treatment of UPJ stenosis in adult and pediatric population. Our objective in this paper is to review the results of minimally invasive surgery as the treatment of UPJ obstruction, the trend to use these approaches and the current limits of LP and RP. METHODS: A review of most relevant papers and meta-analysis about LP and RP in pediatric and adult population was performed using PubMed...

OBJECTIVES: Laparoscopic ureteral reconstructive surgery is routinely performed , because it demonstrated efficacy and safety profiles similar to open surgery in expert hands. The most frequent surgical complications after transplant are urological, appearing in up to 12,5% of the cases; they can compromise graft function and mortality. The most frequent ones include ureterovesical anastomosis stenosis (2,5-7,5%) and vesicoureteral reflux (0,4-2,2), which present in up to 80% of the cases...

M Cassano
Surgical closure of nasal septal perforation is one of the most challenging procedures in nasal surgery. During the last decade, many endoscopic repair techniques have been described with a success of post-operative repair between 76.4% and 100%. The advantages of this approach are its minimal invasiveness (with no external scars), optimal exposure of the operative field (with better visibility of structures) and good control of perforation margins. The drawbacks are that it is time-consuming and can be difficult to perform, requiring years of endoscopic experience...

Ashley Russo, Vivian E Strong
The World Health Organization (WHO) has declared gastric carcinoma a global health concern and gastric cancer remains the third leading cause of cancer deaths worldwide. With the rising incidence of gastric cancer, a body of both retrospective and randomized data has emerged since the early 1990's evaluating the role of minimally invasive platforms in the management of gastric cancer. While Eastern studies have shown that the laparoscopic approach is safe and feasible for advanced gastric cancer in Eastern patients, it is not clear whether this is true for patients in the West...

The critical shortage of donor organs has spurred investigation of alternative approaches to either generate replacement organs or implant exogenous cells for treatment of end-stage organ failure. Non-thermal irreversible electroporation (NTIRE), which uses brief high electric field pulses to induce irreversible permeabilization of cell membranes, has emerged as a technique for tumor ablation. Here, we introduce a new application for NTIRE that employs in situ cell ablation to create a niche within a solid organ for engraftment of exogenous cells in vivo...

BACKGROUND: Extreme lateral interbody fusion (ELIF) has gained popularity as minimally invasive technique for indirect decompression. However, graft subsidence potentially threatens the long-term success of ELIF. The aim of the study was to evaluate whether 26mm wide cages can eliminate subsidence and subsequent loss of decompression in ELIF. METHODS: Patients undergoing ELIF surgery using a 26mm wide cage were analyzed retrospectively. Patient demographics and peri-operative data for radiographic and clinical outcomes were recorded...
