The aim of this study was to describe a new technique for laparoscopic removal of large ovarian cystic masses. The authors performed a retrospective study during the period January 2008 to December 2009 in the Second Department of Obstetrics and Gynecology of Aretaieion University Hospital; 19 women with large ovarian cysts were included in the study. During the study period, 53 women underwent laparoscopic excision of ovarian cysts. Among them, 19 had very large complex ovarian cysts with a mean diameter of 8.4 cm. The mean age of the patients was 32.1 years. Ultrasound examination revealed findings suggestive of benign disease in all patients. In 8 out of 19 patients CA-125 levels were elevated, ranging from 40.5 to 194.7 IU/mL. A 5-mm suprapubic trocar was directly inserted into the cyst and fluid contents aspirated, so the decompressed cyst could fit in a 5-cm laparoscopic bag. The cyst wall was carefully detached from the healthy ovarian tissue and placed in the bag without any spillage. The remaining cyst wall was removed from the peritoneal cavity with the laparoscopic bag. The mean operative time was 45 minutes. No operative or postoperative complications were noted. There was no conversion to laparotomy. Mean hospital stay was 1 day. Pathology revealed 7 endometriomas, 3 mucinous cystadenomas, 3 serous cystadenomas, 3 serous cysts, and 3 teratomas. Direct trocar insertion within the ovarian cyst followed by aspiration of the fluid contents is a safe and feasible method for the laparoscopic management of large ovarian cysts.

Robot-assisted surgery is gaining momentum as a new trend in minimally invasive surgery. With limited evidence supporting its use in place of the far less expensive conventional laparoscopic surgery, it has been suggested that marketing pressure is partly responsible for its widespread adoption. The impact of phrases that promote the novelty of robot-assisted surgery on patient decision making has not been investigated. We conducted a discrete choice experiment to elicit preference of partial colectomy technique for a hypothetical diagnosis of colon cancer. A convenience sample of 38 participants in an ambulatory general surgery clinic consented to participate. Each participant made 2 treatment decisions between robot-assisted surgery and conventional laparoscopic surgery, with robot-assisted surgery described as “innovative” and “state-of-the-art” in one of the decisions (marketing frame), and by a disclosure of the uncertainty of available evidence in the other (evidence-based frame). The magnitude of the framing effect was large with 12 of 38 subjects (31.6%, P = .005) selecting robot-assisted surgery in the marketing frame and not the evidence-based frame. This is the first study to our knowledge to demonstrate that words that highlight novelty have an important influence on patient preference for robot-assisted surgery and that use of more neutral language can mitigate this effect.

Introduction. Longo’s technique (or PPH technique) is well known worldwide. Meta-analysis suggests that the failure due to persistence or recurrence is close to 7.7%. One of the reasons for the recurrence is the treatment of the advanced hemorrhoidal prolapse with a single stapling device, which is not enough to resect the appropriate amount of prolapse. Materials and methods. We describe the application of “Double PPH Technique” (D-PPH) to treat large hemorrhoidal prolapses. We performed a multicentric, prospective, and nonrandomized trial from July 2008 to July 2009, wherein 2 groups of patients with prolapse and hemorrhoids were treated with a single PPH or a D-PPH. Results were compared. The primary outcome was evaluation of safety and efficacy of the D-PPH procedure in selected patients with large hemorrhoidal prolapse. Results. In all, 281 consecutive patients suffering from hemorrhoidal prolapse underwent surgery, of whom 74 were assigned intraoperatively to D-PPH, whereas 207 underwent single PPH. Postoperative complications were 5% in both groups (P = .32), in particular: postoperative major bleeding 3.0% in PPH versus 4.1% D-PPH (P = .59); pain 37.9 % PPH versus 27.3% D-PPH (mean visual analog scale [VAS] = 2.5 vs 2.9, respectively; P = .72); and fecal urgency 2.1% PPH versus 5.7% D-PPH (P = .8). Persistence of hemorrhoidal prolapse at 12-month follow-up was 3.7% in the PPH group versus 5.9% in the D-PPH group (P = .5). Conclusions. Our data support the hypothesis that an accurate intraoperative patient selection for single (PPH) or double (D-PPH) stapled technique will lower in a significant way the incidence of recurrence after Longo’s procedure for hemorrhoidal prolapse.

Surgical treatment in patients with peritoneal carcinomatosis is often limited by the extent of small bowel involvement. We investigated the results of the application of cold-plasma coagulation on the surface of the small bowel.

The burden of global cataract blindness continues to rise, because the number of surgical ophthalmologists is insufficient, and they are unevenly distributed. There is an urgent need to train surgeons quickly and comprehensively in high-quality, low-cost cataract removal techniques. The authors suggest manual small-incision cataract surgery as a safe alternative to phacoemulsification cataract surgery in the developing world. They discuss the development of a novel, full-immersion, physics-based surgical training simulator as the centerpiece of a scalable, comprehensive training system for manual small-incision cataract surgery.

Virtual reality (VR)-based simulations offer rich opportunities for surgical skill training and assessment of surgical novices and experts. A structured evaluation and validation process of such training and assessment tools is necessary for effective surgical learning environments.

The main limitation of perfusion assessment with indocyanine green fluorescence angiography during colorectal surgery is that the surgeon assesses the quality of perfusion subjectively. The ideal intestinal viability test must be minimally invasive, objective, and reproducible. We evaluated the quantitativity and reproducibility of laser speckle contrast imaging for perfusion assessment during colorectal surgery.

With the availability of low-cost head-mounted displays (HMDs), virtual reality environments (VREs) are increasingly being used in medicine for teaching and clinical purposes. Our aim was to develop an interactive, user-friendly VRE for tridimensional visualization of patient-specific organs, establishing a workflow to transfer 3-dimensional (3D) models from imaging datasets to our immersive VRE.

Nowadays, minimally invasive video-assisted thyroidectomy (MIVAT) is considered a safe and effective option. However, its complication rate has not been specifically discussed yet. The aim of this systematic review was enrolling a large number of studies to estimate early and late complications (transient and definitive, uni- and bilateral laryngeal nerve palsy; transient and definitive hypocalcemia; cervical hematoma; hypertrophic or keloid scar) of MIVAT compared with conventional technique.

To compare outcomes of hemorrhoid artery ligation with recto-anal repair (HAL-RAR) and excisional hemorrhoidectomy (EH). The primary objective was to compare postoperative pain, and the secondary objectives were the following: symptom resolution rates, postoperative morbidity, recurrence, and changes in quality of life.
