Superior Turbinectomy: Role for a Two-surgeon Technique in Endoscopic Endonasal Transsphenoidal Surgery—Technical Note

We describe a practical technique of superior turbinectomy followed by posterior ethmoidectomy as a less invasive procedure for two-surgeon technique on endoscopic endonasal transsphenoidal surgery. After identification of the superior turbinate and the sphenoid ostium, the inferior third portion of the superior turbinate was coagulated and resected. This partial superior turbinectomy procedure exposed the posterior ethmoidal sinus. Resection of the bony walls between the sphenoid and posterior ethmoid sinuses provided more lateral and superior exposure of the sphenoid sinus. This technique was performed in 56 patients with midline skull base lesions, including 49 pituitary adenomas and 7 other lesions. Meticulous manipulation of instruments was performed in all cases without surgical complications such as permanent hyposmia/anosmia or nasal bleeding. Our findings suggested that the partial superior turbinectomy followed by retrograde posterior ethmoidectomy is a simple and safe technique providing a sufficient surgical corridor for two-surgeon technique to approaching midline skull base regions, mainly involving pituitary adenomas.     

Epiploic Appendagitis: Is There Need for Surgery to Confirm Diagnosis in Spite of Clinical and Radiological Findings?

Background  

The present retrospective study was conducted to review the authors’ experience and describe clinical and radiologic features of epiploic appendagitis (EA), which is an uncommon, self-limiting clinical entity mimicking acute appendicitis and diverticulitis. Awareness of the features of EA would allow a correct diagnosis and avoid unnecessary surgical interventions.     

Endoscopic Transnasal Surgery as a Replacement for Maxillotomy Techniques to Approach the Central Skull Base: Fewer Complications and More Acceptable to Patients?

Objectives To compare the complication rates of endoscopic transnasal and open maxillotomy approaches for the central skull base. Design Retrospective review. Setting Single-center study, London, United Kingdom. Participants From 1992 to 2012, 81 patients underwent surgery for skull base lesions, 59 by maxillotomy and 22 by endoscopy. Main Outcome Measures Total time of surgical anesthesia, blood loss, complications, duration of tracheal intubation, duration of hospital stay, myelopathy score, and mortality rate. Results The surgical time, blood loss, and duration of the postoperative intubation period were significantly less with endoscopy (p < 0.001). Requirements for intensive care, ward stay, and total hospital stay were also significantly less in the endoscopic group (p = 0.01, p < 0.001, and p < 0.001, respectively). The complication rate was lower with transnasal endoscopic surgery. Conclusion In patients for whom open maxillotomy or endoscopic surgery are both feasible, the preference should be to perform endoscopic surgery, with better visualization and fewer complications.     

The Use of a Compression Device as an Alternative to Hand-Sewn and Stapled Colorectal Anastomoses: Is Three a Crowd?

Background  

The NiTi CAR™ 27 is a newer device that uses compression to create an anastomosis. An analysis of this device in the creation of colorectal anastomoses in humans has yet to be reported in the USA.     

An Operating Microscope with Higher Magnification and Higher Resolution for Cerebral Aneurysm Surgery: Preliminary Experience—Technical Note

We describe a higher magnifying power operating microscope system to improve one method of high-quality microsurgical clipping for cerebral aneurysm in some cases. This higher magnification is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnifications (distinctiveness of 7 μm). This higher-resolution operating microscope system provides the surgeon with higher-magnified images (at the maximum of more than 30× magnifications as each working distance) in the operating field. The magnifications can be changed from low power (2.9×) to high power (62.0×) depending on the circumstances in a given procedure. We have used this operating microscope system on 11 patients with microsurgical clipping for cerebral aneurysms. Microsurgical treatment could be performed safely and precisely. All aneurysms were treated without any technical complications. We think that the use of this microscope would have potential benefits for microsurgical treatment for cerebral aneurysms because of better visualization.     

Hypogonadism as a New Comorbidity in Male Patient's Selection for Bariatric Surgery: Towards an Extended Concept of Metabolic Surgery?

Hypogonadism and subfertility can be frequently associated to obesity. These endocrine alterations may have consequences in the health and quality of life of obese men since they may result in impaired fertility and poor sexual life. As many clinical reports suggest, weight loss can ameliorate hypogonadism and, more generally, alterations in sex hormones. This effect is evident even when weight loss is induced by bariatric surgery. The evidence that hypogonadism in morbidly obese patients can regress after bariatric surgery should lead us to consider it as a modifiable comorbidity associated to obesity. This would have as a consequence that obese male patients with symptomatic hypogonadism could be candidates for bariatric surgery even with a BMI?<?40 kg/m². Controlled clinical trials, involving obese hypogonadal males, should be encouraged.     

Surgical Site Infection in General and Thoracic Surgery: Surveillance of 2 663 Cases in a Japanese Teaching Hospital

Purpose We conducted a prospective survey of 2 663 surgical patients in a Japanese teaching hospital to look for any risk factors predisposing to surgical site infection (SSI) other than the National Nosocomial Infection Surveillance (NNIS) System risk indices; namely, performance status, operative time, wound classification, and endoscopic use. Methods Our Infection Control Team recorded data for 5 years using the Japanese SSI surveillance system. We divided the incidence of SSI for each risk index category by the NNIS reference data to produce the standardized infection ratio (SIR). Results The representative procedure, SSI rate, and SIR in the 2663 patients were as follows: colectomy, 6.0%, 0.917; esophagectomy, 19.4%, 6.020; mastectomy, 0.5%, 0.401; rectal surgery, 8.7%, 1.136; thoracic surgery, 1.5%, 1.137; and biliary surgery, 13.4%, 1.937. We also found age to be a significant risk factor. Conclusions The NNIS system risk indices should separate rectal surgery from colorectal surgery, and separate esophagectomy from other gastrointestinal surgery. Age should also be included as an SSI risk index.
