Women's Perception of Transgastric and Transvaginal Natural Orifice Transluminal Endoscopic Surgery (NOTES) - Impact of Medical Education, Stage of Life and Cross-Cultural Aspects.

Introduction: Despite that NOTES produces at least matchable clinical long-term results when compared to laparoscopy, still a restraint within the medical community and among patients is evident. Consequently, it might be meaningful to evaluate factors of patient's NOTES perception to promote its acceptance. NOTES is still quite novel and questionnaires regarding its perception by the public is still lacking even so in the Middle East.

Technical aspects of paediatric robotic pancreatic enucleation based on a case of an insulinoma.

Background: Insulinomas are rare insulin-producing pancreatic neuroendocrine tumours leading to severe episodes of hypoglycaemia. Surgery is the predominant curative therapy.

Methods: We report here the first paediatric case of an insulinoma of the pancreatic body resected completely robotically under ultrasound guidance in a 10-year-old male with multiple endocrine neoplasia type 1.

Added value of surgical interdisciplinarity- The Joel-Cohen's abdominal incision.

Background: Surgical methods have profited from the exchange of knowledge among different specialties. Endoscopy which was introduced by gynecologists, surgeons, and internists is used now by all disciplines, and most of yesterday's laparotomies have now endoscopic alternatives. However, laparotomies are still needed, and there is no agreement among surgeons about what is the optimal abdominal incision.

Impact of ASA-score, age and learning curve on early outcome in the initiation phase of an oncological robotic colorectal program.

The ASA score is known to be an independent predictor of complications and mortality following colorectal surgery. We evaluated early outcome in the initiation phase of a robotic oncological colorectal resection program in dependence of comorbidity and learning curve. 43 consecutive colorectal cancer patients (median age: 74 years) who underwent robotic surgery were firstly analysed defined by physical status (group A = ASA1 + 2; group B = ASA3).

Platelets Boost Recruitment of CD133 Bone Marrow Stem Cells to Endothelium and the Rodent Liver-The Role of P-Selectin/PSGL-1 Interactions.

We previously demonstrated that clinical administration of mobilized CD133 bone marrow stem cells (BMSC) accelerates hepatic regeneration. Here, we investigated the potential of platelets to modulate CD133BMSC homing to hepatic endothelial cells and sequestration to warm ischemic livers. Modulatory effects of platelets on the adhesion of CD133BMSC to human and mouse liver-sinusoidal- and micro- endothelial cells (EC) respectively were evaluated in in vitro co-culture systems.

Dorsal Track Control (DTC): A Modified Surgical Technique for Atraumatic Handling of the Distal Esophagus in Esophagojejunostomy.

Surgical therapy for adenocarcinoma of the esophagogastric junction II requires distal esophagectomy, in which a transhiatal management of the lower esophagus is critical. The 'dorsal track control' (DTC) maneuver presented here facilitates the atraumatic handling of the distal esophagus, in preparation for a circular-stapled esophagojejunostomy. It is based on a ventral semicircular incision in the distal esophagus, with an intact dorsal wall for traction control of the esophagus.

A standardized suprapubic bottom-to-up approach in robotic right colectomy: technical and oncological advances for complete mesocolic excision (CME).

Backround: Several studies have demonstrated a direct correlation between lymph node yield and survival after colectomy for cancer. Complete mesocolic excision (CME) in right colectomy (RC) reduces local recurrence but is technically demanding. Here we report our early single center experience with robotic right colectomy comparing our standardized bottom-to-up (BTU) approach of robotic RC with CME and central vessel ligation (CVL) facilitated by a suprapubic access with the "classical" medial-to-lateral (MTL) strategy.

A Role for NF-κB in Organ Specific Cancer and Cancer Stem Cells.

Cancer stem cells (CSCs) account for tumor initiation, invasiveness, metastasis, and recurrence in a broad range of human cancers. Although being a key player in cancer development and progression by stimulating proliferation and metastasis and preventing apoptosis, the role of the transcription factor NF-κB in cancer stem cells is still underestimated. In the present review, we will evaluate the role of NF-κB in CSCs of glioblastoma multiforme, ovarian cancer, multiple myeloma, lung cancer, colon cancer, prostate cancer, as well as cancer of the bone.

CD133 bone marrow stem cells (BMSC) control platelet activation - Role of ectoNTPDase-1 (CD39).

Background: We previously demonstrated CD133+ bone marrow stem cells (BMSC) to promote hepatic proliferation for liver regeneration. Here, we evaluated the capacity of CD133+BMSC to utilize platelets for homing to vasculature and concomitant controlling their aggregability upon ADP stimulation.

Methods: CD133+BMSC and platelets were co-cultured along micro endothelial cells under variable flow conditions and tested for homing levels along vasculature.

Hybrid techniques and patients' safety in implementing transoral sublingual thyroidectomy.

Purpose: Cosmetic advantages and minimally invasive aspects become more and more important for patients undergoing thyroidectomy. We report on our personal experience and conceptual design in dealing with approaches to the thyroid gland, which we were the first to describe. We report on ideas and experiences concerning its implementation.

Laparoscopic cholecystectomy versus transvaginal natural orifice transluminal endoscopic surgery cholecystectomy: results of a prospective comparative single-center study.

Background And Aims: Laparoscopic cholecystectomy (LC) in female individuals has been challenged recently by transvaginal natural orifice transluminal endoscopic surgery cholecystectomy (TVC). TVC has not been widely accepted as a standard procedure, even though it is reported to be a safe and painless alternative to LC. This prospective comparative study aims to not only prove equality of TVC and LC but to underline the advantages of TVC over LC with regard to postoperative pain.

Exploring the umbilical and vaginal port during minimally invasive surgery.

This article focuses on the anatomy, literature, and our own experiences in an effort to assist in the decision-making process of choosing between an umbilical or vaginal port. Umbilical access is more familiar to general surgeons; it is thicker than the transvaginal entry, and has more nerve endings and sensory innervations. This combination increases tissue damage and pain in the umbilical port site.

Transoral thyroidectomy: limitations, patients' safety, and own experiences.

For patients undergoing thyroidectomy, the minimally invasive aspect and the cosmetic advantage of the procedure seem to be important factors in surgery. Studies in cadaver and animals have shown that different endoscopic techniques can be performed in a safe and successful way. In the evolution of thyroid surgery, for many endocrine surgeons, the transoral approach seems to be the next step.

Endoscopic thyroidectomy: the transoral approach.

Transoral endoscopic thyroid surgery seems to be the logical consequence in the evolution of thyroid surgery. Animal and cadaver studies have shown that different endoscopic techniques can be performed in a safe and successful way. Presently, the minimally invasive aspect and cosmetic advantage seem to be the most important factor for the patients.
