Objective: To introduce a new telesurgical concept and system, we describe the TELELAP Alf-X system and report the results of the preliminary laboratory experiments on dry lab skill exercises.
Methods: The TELELAP Alf-X system offers a novel approach to remotely operated 3-dimension endoscopy by adding haptic sensation, an eye-tracking system, and a high degree of configuration versatility. The Alf-X system consists of a remote control unit, manipulator arms, connection node, and reusable endoscopic instruments. To test the hand-eye coordination, manual dexterity, depth of field, and ability to make optimal sutures and knots, the Alf-X system was used in a laparoscopic trainer utilizing specific tools by a single surgeon (SG) who repeated three different exercises ten times. The time and accuracy of the exercises were recorded.
Results: By using the TELELAP Alf-X system, the surgeon was able to work repeatedly and to perform all the exercises scheduled. In all exercises, the best results were achieved after the first five cases.
Conclusion: The TELELAP Alf-X system shows excellent stability, easy-to-use interface, and ability to perform essential endoscopic skills. Further experimentation, especially in live tissue, could identify the role of this new technology for the surgical repertoire.
Laparoscopic Fluorescence Angiography with Indocyanine Green to Control the Perfusion of Gastrointestinal Anastomoses Intraoperatively

The principle of fluorescence angiography using indocyanine green has been known for a long time and was used especially by photographs and ophthalmologists for retinal diagnostics. After one publication about perfusion control in open surgery we were the first who examined the perfusion of colorectal anastomoses by laparoscopic fluorescence angiography intraoperatively. Since 2008, 49 laparoscopic operations (45 colorectal anastomoses, 4 gastric sleeve resections) were performed using the fluorescence control. In all cases a correct perfusion of the anastomotic/stapler region could be shown. In cases of decreased perfusion a resection of this area could have been necessary. The laboratory tests with isolated, perfused pig colon could show areas with hypoperfusion after dissection of segmental arteries. Laparoscopic fluorescence angiography could become a standard method to detect a decreased perfusion intraoperatively. Further studies will be needed to show if the rate of anastomotic insufficiency can be lowered by using this new method.

Background: Laparoscopic hepatic surgery has only recently become an established field. Technological limitations in devices used to transect the liver parenchyma and control hemostasis have been a rate limiting step. However, as a result of advances in products specifically tailored to liver surgery, there has been steady progress in the complexity of laparoscopic hepatectomies performed, from the minimally invasive fenestration of liver cysts, to peripheral wedge resections, major hepatectomy, and recently donor hepatectomy. Herein, we discuss the role of several laparoscopic devices which include the endoscopic stapler, pre-coagulators, ultrasonic dissector, ultrasonic shears, and vessel sealing devices. Conclusion: Laparoscopic liver surgery introduces new challenges to even the experienced surgeon. It is important to have a solid understanding of the advantages and limitations of available instruments in order to safely and effectively expand the use of laparoscopy in hepatic surgery.

There are few options for the treatment of fistulas, leaks, and perforations endoscopically. Here we describe our experience with an endoscopic clipping system. A retrospective review of all cases using the Over-The-Scope-Clip system (Ovesco Endoscopy AG, Tuebingen, Germany) was performed. The system was utilized in ten patients with gastrointestinal surgical complications. Four patients had gastric leaks following sleeve gastrectomy, one had a post-operative colonic leak, two had gastro-gastric fistulas following gastric bypass, and three had esophageal perforations. Two leak patients had complete resolution, one had a contained leak following clip placement that was clinically insignificant, and the fourth patient had a persistent leak despite two clipping procedures. Two patients had gastro-gastric fistulas following roux-en-y gastric bypass surgery and, while they both had initial success, the fistulas recurred. One patient presented with anastomotic leak following colon resection but the system was unable to reach the treatment site. Three patients were successfully treated for esophageal perforation. There were no complications.
The Safety and Biocompatibility of Gelatin Hemostatic Matrix (Floseal and Surgiflo) in Neurosurgical Procedures

Adequate hemostasis in cranial and spinal surgery is of paramount importance in a neurosurgeon's daily practice. Generalized ooze bleeding from the surgical wall cavities, coming from the dura mater or nervous tissue may be troublesome and may limit visualization in minimally invasive neurosurgery. Hemostatic matrix is a mixture of a flowable gelatin matrix (bovine or porcine) and a thrombin component mixed together. A total of 318 patients undergoing cranial, craniospinal, and spinal procedure with the use of gelatin hemostatic matrix (Floseal and Surgiflo) were enrolled in this clinical study. We compared the different hemostatic techniques using the gelatin hemostatic matrix, and investigated indications, time to bleeding control, and its efficacy and safety in neurosurgery.
The Use of Rotational Bladder Flap and Hemostatic Matrix Sealant (FloSeal): A Modified Transabdominal Approach to Repair Supratrigonal and Complex Vesicovaginal Fistula

Vesicovaginal fistula (VVF), commonly caused by prolonged obstructed labor, is one of the worst complications of childbirth and poor obstetric care in the developing world. We investigated the clinical efficacy and outcome of technical modifications of the current transperitoneal supravesical technique for supratrigonal and complex vesicovaginal fistula. We studied a total of 20 patients with iatrogenic supratrigonal and complex vesicovaginal fistula following obstetric trauma and hysterectomy. All patients underwent a modified transabdominal technique: the modifications consisted of passing a Foley catheter through the fistulous opening, inflating the balloon, and applying traction on the catheter to provide effective anchorage and to minimize the oozing from the cystotomy edges. The cystotomy was directed in the parasagittal line, and medial side of the bladder was rotated as a flap into the bladder defect; the urethral de Pezzare catheter was used for urinary drainage. We used hemostatic matrix sealant (FloSeal, Baxter BioSurgery, Westlake Village, California) to promote healing and hemostasis. The vesicovaginal fistula was successfully corrected in all patients after the first attempt, and no significant bladder dysfunction or decrease in bladder capacity was seen after repair. Interposition flaps were used in all patients, and six patients (30%) required ancillary procedures for other associated anomalies at the time of fistula repair. At a mean follow-up of two years, fourteen women were sexually active, and 5 (35%) from this group of patients complained of mild-to-moderate dyspareunia. In our study, supratrigonal VVFs were repaired with a transabdominal, transperitoneal, transvesical approach. Tailoring the cystotomy in a parasagittal line permitted closure of fistula by rotation of bladder flap into the defect. This excellent method should be a viable option when repairing complex VVF.
