#1
Mesut Sipahi, Ergin Arslan
PURPOSE: Intracorporeal knot tying in laparoscopic surgery continues to be a problem especially for beginners and inexperienced surgeons. A wide-angle needle holder was designed to make the knot maneuver easier while also ensuring that the knot does not come out of the needle holder. In this study, it was planned to compare the wide-angle needle holder with the classic needle holder in regard to knot tying time. MATERIAL AND METHOD: A total of 11 male volunteers were randomly selected from freshmen students of the faculty of medicine, who had no experience of surgery or laparoscopic surgery...

BACKGROUND: Several techniques have been introduced to treat acromioclavicular (AC) separation using the semitendinosus tendon as a graft for coracoclavicular (CC) ligament reconstruction. However, the tendon may have been used previously or the patient may not want it harvested. Hence, synthetic tendon transfers have become increasingly popular. METHODS: Five patients with chronic AC separations were treated. A synthetic polyurethane urea tendon graft (Artelon Tissue Reinforcement [ATR]) was chosen for its ability to partially transform into connective tissue...

Advanced videoendoscopic equipment (such as motorized drills, chisels, and rongeurs) facilitates the use of modern decompression tools through the inner working channel of the spinal endoscope using the transforaminal approach. Postoperative dysesthetic leg pain, however, is common because of irritation of the dorsal root ganglion. This article presents a novel surgical technique employing an expandable balloon placed into the hollow intervertebral space in patients without any functional disc tissue to distract the stenotic motion segment...

BACKGROUND: Open reduction and internal fixation of rib fractures is recommended to decrease mortality, shorten the duration of mechanical ventilation, and lower hospital length of stay. Prosthetic titanium plates are frequently used to repair chest wall trauma, and are typically contoured to the patient's anatomy at the time of implant in the operating room. We describe the use of 3-dimensional (3D) digitally corrected rapid prototyping to generate a model of a patient's skeletal anatomy for the purposes of preoperative customization of standard titanium plates for fixation of rib fractures...

INTRODUCTION: Preoperative planning is an essential prerequisite for the success of plastic surgery. In procedures such as breast reduction, freehand drawings may be associated with a number of challenges during the determination of axes vertical and parallel to the surgical site. Furthermore, many procedures involve subjective maneuvers, such as attempts aimed at positioning both nipples on the same line and transferring nipple-areola complexes in a well-matched manner. Our newly designed instrument, that is, the goniometer (TG), aims to ensure metric measurements appropriate for the axes, and it may also be used in circumstances that require angle measurements...

It remains unclear if single incision laparoscopic liver surgery is superior to standard multiport resections and in what regard patients might benefit from this approach. We retrospectively analyzed the course of all patients undergoing laparoscopic left lateral sectionectomy at our center between 2009 and 2017. In total, 11 single incision and 31 multiport left lateral sectionectomies were performed at our center between July 2009 and May 2017. Six patients were excluded due to multivisceral resections. Indications included adenoma (n = 7 vs n = 2), focal nodular hyperplasia (n = 4 vs n = 3), hepatocellular carcinoma (n = 4 vs n = 4), colorectal liver metastasis (n = 4 vs n = 0), noncolorectal metastasis (n = 2 vs n = 1), hemangioma (n = 3 vs n = 0), abscess (n = 1 vs n = 0), and cysts (n = 1 vs n = 0)...

PURPOSE: A positive resection margin (RM+) is acknowledged as a poor prognostic factor after gastrectomy. Microsatellite instability (MSI-H) gastric cancer has been identified as a subgroup of gastric cancer that may be associated with an improved prognosis. The aim of the study was an analysis of MSI status on patients with margin involvement after gastrectomy and examination of the association between MSI, margin status, and survival outcomes. METHODS: From a large prospectively annotated surgical database we collected clinicopathological and survival data on patients who had undergone a potentially curative resection for gastric cancer...

BACKGROUND: After surgery for liver tumors, recurrence rates remain high because of residual positive margins or undiagnosed lesions. It has been suggested that detection of hepatic tumors can be obtained with near-infrared fluorescence imaging (FI). Indocyanine green (ICG) has been used with contrasting results. The aims of this study were to explore ICG-FI-guided surgery methodology and to assess its potential applications. MATERIALS AND METHODS: Out of 14 patients with liver tumors, 5 were not operated on, and 9 patients (3 primary and 6 metastatic tumors) underwent surgery...

The aim of this pilot test was to test a new self-locking resorbable implant for hilum occlusion during a video-assisted thoracoscopic lung lobectomy in a surviving pig model. Once the thoracic cavity was assessed and structures identified, the right middle lobe and its respective hilum were exposed. The implant was introduced with a semiclosed loop through a working channel and positioned around the pulmonary lobe. Occlusion was performed with a conventional Crile forceps and a laparoscopic Kelly forceps. Lobe section was done with laparoscopic Metzenbaum scissors and tissue removal through the dorsal access...

BACKGROUND: Combining the strengths of surgical robotics and minimally invasive surgery (MIS) holds the potential to revolutionize surgical interventions. The MIS advantages for the patients are obvious, but the use of instrumentation suitable for MIS often translates in limiting the surgeon capabilities (eg, reduction of dexterity and maneuverability and demanding navigation around organs). To overcome these shortcomings, the application of soft robotics technologies and approaches can be beneficial...

Konstantinos Laios
Professor Samuel David Gross (1805-1884) is considered as one of the founders of American surgery. He was a skillful surgeon who could excellently perform a lithotomy, an amputation, and a cataract surgery. He introduced many new surgical techniques and designed new surgical and medical instruments. He expertise was not limited to surgery alone; he also published studies concerning internal medicine, pathology, experimental physiology, and pharmacology. His most important treatise was his 2-volume work, A System of Surgery, Pathological, Diagnostic, Therapeutic and Operative (1861), which was a standard reference book in surgery in the United States during the second half of 19th century...
