Hysteroscopic myomectomy for submucosal type 2 fibroids with cold enucleation technique and complete fibroid extraction using a double-lumen intracervical cannula.

OBJECTIVE: To introduce a new double-lumen intracervical cannula designed to allow a single-step hysteroscopic myomectomy with nonfragmented complete fibroid extraction after cold enucleation of submucosal type 2 fibroids, avoiding complications related to the use of energy and hypo-osmolar solutions. DESIGN: Video article depicting the use of a new double-lumen intracervical cannula for single-step hysteroscopic cold myomectomy, according to our institutional care guidelines and after obtaining the patient's informed consent. (The publication of this video has been authorized by the Institutional Ethics Committee of CES University in Medellín, Colombia.) SETTING(S): Private infertility clinic. PATIENT(S): A 45-year-old woman with abnormal uterine bleeding consisting of polymenorrhea and hypermenorrhea, nonresponsive to medical treatment, caused by three type 2 (FIGO leiomyoma subclassification system) submucosal fibroids of 17, 15, and 13 mm with more than 80% of intramyometrial component. INTERVENTION(S): Hysteroscopic enucleation of three submucosal fibroids performed by blunt dissection using the 30° Bettocchi hysteroscope's bevel under continuous observation of the avascular subcapsular plane of the fibroids. Once full enucleation was attained, cervical dilatation to 12 mm with Hegar plugs was performed followed by intracervical placement of a newly designed double-lumen intracervical cannula that allows the concomitant introduction of the Bettocchi diagnostic hysteroscope and a 5-mm laparoscopic tenaculum into the uterine cavity for complete nonfragmented fibroid extraction under direct visualization. MAIN OUTCOME MEASURE(S): Complete and unfragmented fibroid extraction in a single intervention, absence of surgical complications, and postoperative course. RESULT(S): Ambulatory hysteroscopic myomectomy of three submucosal type 2 fibroids was successfully performed by blunt enucleation and complete nonfragmented fibroid extraction using the double-lumen intracervical cannula. The total operative time was 32 minutes, and the total amount of distension media (normal saline) used was 800 mL with a liquid balance of 50 mL. No surgical or anesthesia-related complications occurred. In the postsurgical evaluation, the patient classified her pain as minimal, giving it a score of 1 on a pain scale of 1 to 5 (in which 1 is the lowest and 5 the highest pain perception). When asked about the level of satisfaction with the surgical procedure, the patient reported the highest degree of satisfaction with a score of 5 on a satisfaction scale of 1 to 5 (in which 1 is the lowest and 5 the highest satisfaction). The patient reported having postsurgical regular menstrual cycles every 28 days and 3 bleeding days without hypermenorrhea. CONCLUSION(S): An efficient hysteroscopic myomectomy of submucosal type 2 fibroids with deep intramyometrial component can be performed with complete and nonfragmented fibroid extraction in a single intervention by using a newly designed double-lumen intracervical cannula. This technique allows the completion of the surgery without the need of a resectoscope, electrosurgery, or hypo-osmolar uterine distension media, thus avoiding potential complications such as thermal-induced myometrial injury and hyponatremia; a second surgical intervention will not be required because the fibroid enucleation is complete. The procedure can be performed with the use of a diagnostic hysteroscope that is widely available in gynecologic practices.

Changing the view: Video versus direct laryngoscopy for intubation in the pediatric emergency department.

The aim of this study was to compare the success of first-attempt tracheal intubation in pediatric patients >1-year old performed using video versus direct laryngoscopy and compare the frequency of tracheal intubation-associated events and desaturation among these patients.Prospective observational cohort study conducted in an Academic pediatric tertiary emergency department. We compared 50 children intubated with Mcgrath Mac video laryngoscope (VL group) and an historical series of 141 children intubated with direct laryngoscopy (DL group). All patients were aged 1 to 18 years.The first attempt success rates were 68% (34/50) and 37.6% (53/141) in the VL and DL groups (P < .01), respectively. There was a lower proportion of tracheal intubation-associated events in the VL group (VL, 31.3% [15/50] vs DL, 67.8% [97/141]; P < .01) and no significant differences in desaturation (VL, 35% [14/50] vs DL 51.8% [72/141]; P = .06). The median number of attempts was 1 (range, 1-5) for the VL group and 2 (range, 1-8) for the DL group (P < .01). Multivariate logistic regression showed that video laryngoscope use was associated with higher chances of first-attempt intubation with an odds ratio of 4.5 (95% confidence interval, 1.9-10.4, P < 0.01).Compared with direct laryngoscopy, VL was associated with higher success rates of first-attempt tracheal intubations and lower rates of tracheal intubation-associated events.

Introduction: A relevant aspect in pediatric anesthesia is the management of the airway. Anatomical differences in this population makes them more susceptible to devices designed for their management. Video laryngoscopy improves panoramic vision of the glottis. Objective: To compare the use of video laryngoscopy with direct laryngoscopy for orotracheal intubation in pediatric patients. Methods: With an observational descriptive design, 276 cases were studied, patients from 5 to 17 years old, undergoing planned surgery, with general anesthesia plus orotracheal intubation. The specialist decided on the handling device. The data was transcribed from the forms and analyzed with the SPSS 22.0 program. The descriptive analysis was based on median, mode, average, minimum value, maximum value. Standard deviation and range dispersion measurements. A value of p ≤ 0.05 was considered statistically significant. Results: The average age of the study was 9.83 years. With direct laryngoscopy 97.4% intubation was performed at the first attempt and with video laryngoscopy 88.4% (p = 0.003). In 94.2% of cases of direct laryngoscopy, a successful intubation was performed in less than 10 seconds, with video laryngoscopy it was 75.2% (p = 0.000). Complications occurred in 6.6% of intubations with video laryngoscopy versus 2.6% with conventional laryngoscopy (p = 0.103). 56.2% of specialists prefer direct laryngoscopy to manage a pediatric airway without predictors of difficulty. Conclusions: Video laryngoscopy provides additional support in routine airway management, always requiring prior knowledge and skills. The evidence to support one technique over another is insufficient.

Video-assisted ovariohysterectomy in domestic cats (Felis catus, Linnaeus, 1758) using two access portals.

PURPOSE: To describe video-assisted ovariohysterectomy (OHE) with two portals access in adult intact queens. METHODS Fifty-two females cats were used. A 4 mm cannula was positioned in the abdomen through an incision close to the umbilicus (first portal), and a pneumoperitoneum was established. A second portal was positioned in the midline of the pre-pubic region. Females were positioned in right lateral recumbency to locate the left ovarian pedicle, and the uterine horn was held by a transcutaneous suture. The pedicle was cauterized and incised. The procedure was then performed on the contralateral ovary. The ovaries were exteriorized from the abdomen, along with the uterus, through the second access point. The uterine body was exposed, fixed and sectioned, and the abdominal incisions were sutured. RESULTS Surgeries were performed in an average of 41.4±14.2 minutes. The main complications included hypotension (7.7%) and subcutaneous emphysema (7.7%), and 13.5% of the surgeries were converted to laparotomy. CONCLUSION Ovariohysterectomy using a video-assisted technique and two access portals is safe, has minimal risks and is effective for the spaying of queens.

Catheter for Cleaning Surgical Optics During Surgical Procedures: A Possible Solution for Residue Buildup and Fogging in Video Surgery.

Currently, there is a tendency to perform surgical procedures via laparoscopic or thoracoscopic access. However, even with the impressive technological advancement in surgical materials, such as improvement in quality of monitors, light sources, and optical fibers, surgeons have to face simple problems that can greatly hinder surgery by video. One is the formation of "fog" or residue buildup on the lens, causing decreased visibility. Intracavitary techniques for cleaning surgical optics and preventing fog formation have been described; however, some of these techniques employ the use of expensive and complex devices designed solely for this purpose. Moreover, these techniques allow the cleaning of surgical optics when they becomes dirty, which does not prevent the accumulation of residue in the optics. To solve this problem we have designed a device that allows cleaning the optics with no surgical stops and prevents the fogging and residue accumulation. The objective of this study is to evaluate through experimental testing the effectiveness of a simple device that prevents the accumulation of residue and fogging of optics used in surgical procedures performed through thoracoscopic or laparoscopic access. Ex-vivo experiments were performed simulating the conditions of residue presence in surgical optics during a video surgery. The experiment consists in immersing the optics and catheter set connected to the IV line with crystalloid solution in three types of materials: blood, blood plus fat solution, and 200 mL of distilled water and 1 vial of methylene blue. The optics coupled to the device were immersed in 200 mL of each type of residue, repeating each immersion 10 times for each distinct residue for both thirty and zero degrees optics, totaling 420 experiments. A success rate of 98.1% was observed after the experiments, in these cases the device was able to clean and prevent the residue accumulation in the optics.

New head-mounted display system applied to endoscopic management of upper urinary tract carcinomas

Purpose We tested a new head-mounted display (HMD) system for surgery on the upper urinary tract. Surgical Technique Four women and one man with abnormal findings in the renal pelvis on computed tomography and magnetic resonance imaging underwent surgery using this new system. A high definition HMD (Sony, Tokyo, Japan) is connected to a flexible ureteroscope (Olympus, Tokyo, Japan) and the images from the ureteroscope are delivered simultaneously to various participants wearing HMDs. Furthermore, various information in addition to that available through the endoscope, such as the narrow band image, the fluoroscope, input from a video camera mounted on the lead surgeon’s HMD and the vital monitors can be viewed on each HMD. Results Median operative duration and anesthesia time were 53 and 111 minutes, respectively. The ureteroscopic procedures were successfully performed in all cases. There were no notable negative outcomes or incidents (Clavien-Dindo grade ≥1). Conclusion The HMD system offers simultaneous, high-quality magnified imagery in front of the eyes, regardless of head position, to those participating in the endoscopic procedures. This affordable display system also provides various forms of information related to examinations and operations while allowing direct vision and navigated vision. .

Single-incision videolaparoscopic appendectomy with conventional videolaparoscopy equipment.

BACKGROUND: Acute appendicitis is the most common surgical emergency in daily practice, and is approached laparoscopically in many centers. Efforts have been undertaken for the development of minimally invasive techniques that reduce tissue trauma and offer improved cosmetic results, one of such being the single-incision laparoscopic surgery (SILS). AIM: To present a minimally invasive technique for appendectomy (SILS) undertaken with conventional instruments. METHOD: Eleven patients were treated in the emergency care center presenting abdominal pain in the right iliac fossa that was suggestive of appendicitis. Diagnostic investigation was subsequently conducted, including physical examination, laboratory and imaging exams (CT scan with intravenous contrast or total abdominal ultrasound), and the results were consistent with acute appendicitis. Thus, after consent, these patients underwent SILS appendectomy under general anesthesia with three trocars (two 10 mm and one 5 mm), using conventional and optical laparoscopic tweezers (10 mm, 30º). The base and pedicle of the appendix were ligated with titanium LT 400 clips. The procedure occurred uneventfully. Inclusion criteria were absence of diffuse peritonitis, BMI (body mass index) less than 35 and absence of serious comorbidities or sepsis. RESULTS: Seven men and four women were operated with average age of 25.7 years and underwent appendectomy through this technique. Mean procedure duration was of 37.2 min. Regarding surgical findings, three had appendicitis in stage 1, four in stage 2 and four in stage 3. All patients improved well, without surgical complications, and did not require conversion to open surgery or conventional laparoscopy technique. CONCLUSION: Appendectomy conducted through Single Incision Laparoscopic Surgery is a feasible and promising technique that can be performed with conventional laparoscopic instruments.

Video-assisted anal fistula treatment: technical considerations and preliminary results of the first Brazilian experience.

BACKGROUND: Anorectal fistula represents an epithelized communication path of infectious origin between the rectum or anal canal and the perianal region. The association of endoscopic surgery with the minimally invasive approach led to the development of the video-assisted anal fistula treatment. AIM: To describe the technique and initial experience with the technique video-assisted for anal fistula treatment. TECHNIQUE: A Karl Storz video equipment was used. Main steps included the visualization of the fistula tract using the fistuloscope, the correct localization of the internal fistula opening under direct vision, endoscopic treatment of the fistula and closure of the internal opening which can be accomplished through firing a stapler, cutaneous-mucosal flap, or direct closure using suture. RESULTS: The mean distance between the anal verge and the external anal orifice was 5.5 cm. Mean operative time was 31.75 min. In all cases, the internal fistula opening could be identified after complete fistuloscopy. In all cases, internal fistula opening was closed using full-thickness suture. There were no intraoperative or postoperative complications. After a 5-month follow-up, recurrence was observed in one (12.5%) patient. CONCLUSION: Video-assisted anal fistula treatment is feasible, reproducible, and safe. It enables direct visualization of the fistula tract, internal opening and secondary paths.

Comparison of the TruView infant EVO2 PCD™ and C-MAC video laryngoscopes with direct Macintosh laryngoscopy for routine tracheal intubation in infants with normal airways.

OBJECTIVE: Videolaryngoscopy has mainly been developed to facilitate difficult airway intubation. However, there is a lack of studies demonstrating this method's efficacy in pediatric patients. The aim of the present study was to compare the TruView infant EVO2 and the C-MAC videolaryngoscope with conventional direct Macintosh laryngoscopy in children with a bodyweight ≤10 kg in terms of intubation conditions and the time to intubation. METHODS: In total, 65 children with a bodyweight ≤10 kg (0-22 months) who had undergone elective surgery requiring endotracheal intubation were retrospectively analyzed. Our database was screened for intubations with the TruView infant EVO2, the C-MAC videolaryngoscope, and conventional direct Macintosh laryngoscopy. The intubation conditions, the time to intubation, and the oxygen saturation before and after intubation were monitored, and demographic data were recorded. Only children with a bodyweight ≤10 kg were included in the analysis. RESULTS: A total of 23 children were intubated using the C-MAC videolaryngoscope, and 22 children were intubated using the TruView EVO2. Additionally, 20 children were intubated using a standard Macintosh blade. The time required for tracheal intubation was significantly longer using the TruView EVO2 (52 sec vs. 28 sec for C-MAC vs. 26 sec for direct LG). However, no significant difference in oxygen saturation was found after intubation. CONCLUSION: All devices allowed excellent visualization of the vocal cords, but the time to intubation was prolonged when the TruView EVO2 was used. The absence of a decline in oxygen saturation may be due to apneic oxygenation via the TruView scope and may provide a margin of safety. In sum, the use of the TruView by a well-trained anesthetist may be an alternative for difficult airway management in pediatric patients.

Surgical infection in a videolaparoscopic cholecystectomy when using peracetic acid for the sterilization of instruments.

OBJECTIVE: To determine the frequency of surgical site infection in patients undergoing laparoscopic cholecystectomy with instruments sterilized by peracetic acid. METHODS: We conducted a retrospective, cohort, descriptive, cross-sectional study. Peracetic acid has been used for sterilization following the protocol recommended by the manufacturer. We observed the criteria and indicators of process and structure for preventing surgical site infection pre and intraoperatively. For epidemiological surveillance, outpatient visits were scheduled for the 15th and between the 30th and 45th days after discharge. RESULTS: Among the 247 patients, there were two cases of surgical site infection (0.8%). One patient was readmitted to systemic antibiotic therapy and percutaneous puncture; in the other the infection was superficial and followed at the clinic. CONCLUSION: Ethical issues prevent the conduction of a prospective study because of peracetic acid have been banned for the sterilization of instruments that penetrate organs and cavities. Nevertheless, these results encourage prospective case-control studies comparing its use (historical control) with ethylene oxide sterilization.

Infecção cirúrgica em colecistectomia videolaparoscópica usando ácido peracético como esterilizante dos instrumentais / Surgical infection in a videolaparoscopic colecistectomy when using peracetic acid for the sterilization of instruments

OBJETIVO: Determinar a frequência de infecção de sítio cirúrgico em pacientes submetidos à colecistectomia videolaparoscópica usando o ácido peracético como esterilizante. MÉTODOS: Foi realizado estudo retrospectivo descritivo do tipo coorte transversal. O ácido peracético foi usado para esterilização seguindo protocolo preconizado pelo fabricante. Foram observados os critérios e indicadores de processo e estrutura para prevenção de infecção de sítio cirúrgico no pré e intraoperatório. Para a vigilância epidemiológica, consultas ambulatoriais eram agendadas para o 15º e entre o 30º e 45º dias após a alta. RESULTADOS: Entre 247 pacientes foram diagnosticados dois casos de infecção de sítio cirúrgico (0,8%). Um paciente reinternou para antibioticoterapia sistêmica e punção percutânea; no outro, a infecção foi superficial e acompanhada ambulatorialmente. CONCLUSÃO: Eticamente não é permitida a realização de um estudo prospectivo pelo fato do ácido peracético ter sido proibido para a esterilização de instrumentais que penetrem em órgãos e cavidades; contudo, estes resultados encorajam estudo prospectivo caso-controle, comparando o uso dele (controle histórico) com a esterilização por óxido de etileno.

Infecção por micobactérias de crescimento rápido após procedimentos videocirúrgicos: a hipótese do glutaraldeído / Rapidly growing mycobacteria infection after videosurgical procedures: the glutaraldehyde hypothesis

Between August 2006 and February 2007, in the state of Rio de Janeiro, Brazil, a massive outbreak of RGM infections after video laparoscopy was mainly associated to the recently described Mycobacterium massiliense species. All confirmed and probable cases reports described the use of high-level disinfection of medical devices by using 2 percent glutaraldehyde (2 percent GA) for 30 min before the surgical procedures. We investigated the susceptibility of the M. massiliense isolates recovered during the outbreak to high-level disinfection after 30 min, 1h, 6h and 10h of exposure to the commercial disinfectants. Reference strains for official mycobactericidal tests such as Mycobacterium abscessus, Mycobacterium bovis, Mycobacterium chelonae, Mycobacterium neoaurum and Mycobacterium smegmatis were included as controls. Although all the reference strains were eliminated in 30 min of exposure to 2 percent GA, we observed the recovery of all M. massiliense clinical isolates even after 10h of exposure. This study suggests that failures in high-level disinfection and the high tolerance of these M. massiliense clinical strains to the 2 percent GA were strongly associated to the magnitude of the outbreak.
