Laparoscopic adrenalectomy: comparison between pneumoperitoneum and the use of a laparoscopic lift device in dog cadavers / Adrenalectomia laparoscópica: comparação entre o pneumoperitônio e o uso de dispositivo paraliftlaparoscopy em cadáveres de cães

This study evaluated the feasibility of abdominal liftfor laparoscopic adrenalectomy and compared it with the conventional laparoscopic technique using pneumoperitoneum with medicinal CO2 in dog cadavers. The total surgical time (TST), adrenalectomy time (AT), and gland integrity after removal were evaluated. Thirty-eight adrenalectomies were performed in 19 cadavers. Regardless of the antimere, the TST was significantly lower in the CO2 procedures than in the lift laparoscopy procedures (P=0.001). When comparing the techniques between antimeres, the TST was significantly higher on the left side with lift laparoscopy than with CO2 (P=0.015) and similar between the techniques on the right side of the animals (P=0.086). In the comparison of AT, regardless of the execution side, no differences were observed between the techniques (P=0.05). The same was observed when AT was evaluated separately using antimeres (P=0.902). Of the 38 adrenals evaluated, 92.1% were removed in a single block, and 32.29% had a superficial lesion in the capsule. There was no difference between the groups in the removal capacity in a single block (P=0.340) and capsule integrity (P=0.287). Abdominal lift for laparoscopic adrenalectomy is a feasible technique in dog cadavers; however, it requires a longer surgical time than the conventional technique. The traction force used to elevate the abdominal wall must be evaluated.

O presente trabalho teve como objetivo avaliar a exequibilidade da adrenalectomia laparoscópica utilizando dispositivo de elevação da parede abdominal via liftlaparoscopy e comparar com a técnica laparoscópica convencional utilizando pneumoperitônio com CO2 medicinal em cadáveres de cães. Para isso, avaliou-se tempo cirúrgico total (TCT), tempo de adrenalectomia (TA) e integridade das glândulas após remoção. Foram realizadas 38 adrenalectomias em 19 cadáveres. Independentemente do antímero, o TCT foi significativamente menor nos procedimentos com CO2 do que com liftlaparoscopy (P=0,001). Na comparação das técnicas entre antímeros, o TCT foi significativamente maior no lado esquerdo com liftlaparoscopy do que com CO2 (P = 0,015) e semelhante entre as técnicas no lado direito dos animais (P=0,086). Já na comparação do TA, independente do lado de execução, não foram observadas diferenças entre os métodos (P=0,05). O mesmo foi observado quando o TA foi avaliado separadamente por antímero (P=0,902). Das 38 adrenais avaliadas, 92,1% foram removidas em um único bloco e destas, 32,29% apresentaram lesão superficial na cápsula. Não houve diferença entre grupos para capacidade de remoção em um único bloco (P=0,340) e da integridade da cápsula (P=0,287). A adrenalectomia laparoscópica por elevação da parede abdominal é factível de ser realizada em cadáveres de cães, entretanto, demanda maior tempo cirúrgico quando comparada à técnica convencional. Além disso, a força de tração empregada para elevar a parede abdominal necessita ser avaliada.

Effectiveness of an inexpensive short-term theoretical-practical course on videosurgery for surgeons in training.

BACKGROUND: The rapid development of video surgery and minimally invasive surgical techniques prompted many studies on the methods of teaching these techniques to young surgeons in training. However, the characteristics of a short-term course that is both easily accessible and efficient for this group of surgeons remain controversial. To investigate this issue, a short-term training method was proposed for first year surgery residents, using inexpensive handmade wooden simulation boxes with the students smartphones as cameras. Its effectiveness was evaluated, as well as possible factors that could influence student performance, such as gender and previous experience with video games. METHODS: Thirty-six first-year General Surgery residents, entering in 2019 and 2020, participated in the study: 21 were males and 15 were females with ages between 22 and 29 years old, (mean 25.47 years). All participants performed a pre-established exercise (placing two simple stitches using a laparoscopic simulator), which was timed and scored. They then participated in a short theoretical-practical course, consisting of an initial lecture followed by 4 exercises on handcrafted wooden laparoscopic video surgery simulators. Afterwards, they were asked to repeat the same exercise from the first step. Finally, they answered a questionnaire that included questions on previous videogame experience. The data were tabulated and submitted to statistical analysis. RESULTS: In the pre-training exercise, 15 (41.66%) participants were able to perform the two simple stitches in the simulator box within the maximum time limit of 5 minutes. After the short course, 22 (61.11%) of participants were able to perform the complete exercise. Improvement in the time to complete the practical exercise was statistically significant (p = 0.0296) after participating in the theoretical-practical course. A better pre- and post-training performance was demonstrated by the 17 participants with experience with video games (p = 0.0116), and a better post-training performance was demonstrated by female participants (p = 0.0405). CONCLUSION: This short-term inexpensive theoretical-practical course in laparoscopic training for surgeons in training was effective in reducing the execution time of a laparoscopic stitch in a simulation box. Previous experience with video games and/or female gender appear to be associated with improved performance.

Efficacy and safety of a device used to prevent fogging and residue buildup on surgical optics during video-assisted thoracic surgical procedures (LacrimaSurg): a pilot in vivo study in 30 patients.

INTRODUCTION: Nowadays the majority of the surgical procedures are video surgeries. Despite technological advances, some problems remain. The buildup of residues in front of the lens is an example of this problem. To solve it, Abreu et al. (Surg Technol Int 26:43-47, 2015) developed LacrimaSurg, which works as a lacrimal duct in the optics preventing fogging and residues buildup on it. This had 98.1% of efficiency in an experimental study. OBJECTIVE: Study feasibility and safety of the device under real surgical conditions. MATERIALS AND METHODS: A pilot study included 30 patients undergoing thoracic procedures using LacrimaSurg. Procedures were recorded for further analysis by investigators. The characteristics of patients (age, sex, body mass index, Charlton comorbidity index), data of environment (Temperatures variances), and data of procedures (type of surgery and duration of it) were recorded. The investigators watched the videos and recorded the residue buildup and fogging events that impaired surgeon's vision. The number of times the optics got dirty, need for further jets of crystalloid solution, and need for mechanical cleaning were collected to evaluate efficacy. Comparative serum measurements of electrolytes before and after surgery were studied. Data were organized and analyzed by simple linear correlations and t test for continuous variables and Fisher's test for categorical variables. RESULTS: The use of the device allowed 97% of the procedures to be performed without interruption. No characteristics inherent to the patients or to the procedures that lead to fogging or filth of the optics were identified. There were no statistically significant differences between pre- and postoperative serum ions, and no postoperative complications related to the use of the device were observed. CONCLUSION: The device was effective in preventing interruption of surgical procedures due to dirt or fogging, its use was considered safe, and did not cause postoperative complications.

Sex identification of the ornamental amazon fish Astronotus ocellatus by videoceloscopy and gonadal biopsy.

This study was conducted to evaluate and validate the efficacy and safety of videoceloscopy and gonadal biopsy as sexing methods for the A. ocellatus. A total of 31 adult individuals were used. Florfenicol (50 mg/kg) and morphine (5 mg/kg) were administered intramuscularly during the pre-surgical period. Animals were maintained in a supine position preceding a ventral midline incision and endoscope optics were then utilized for gonad visualization and sex identification. A gonadal fragment was collected using laparoscopic forceps and conditioned in 10 % formalin. To suture the cavity, polyamide yarn was used in a simple and continuous pattern. At 15 days subsequent to surgery, healing was evaluated, and the stitches were removed. Videoceloscopy accuracy and gonadal biopsy effectiveness were 97 % and 83 %, respectively. Total time devoted in the videoceloscopy, gonadal biopsy and surgery was longer for animals identified as males compared to females The survival rate was 100 %. There were differences regarding food consumption at 24 and 36 h post-surgery when compared to control specimens (pre-surgical) Regarding position in the water column, differences were observed at 24 and 72 h after surgery when compared individually to the control specimens. There were differences for interaction behavior at 24, 36 and 60 h, and regarding search for hiding places at 12 and 24 h after surgery in relation to the control specimens. The applied videoceloscopy and gonadal biopsy surgical techniques are, therefore, effective and safe for A. ocellatus sexing procedures.

Hernioplastia com aplicação de tela por laparoscopia em equino com hérnia incisional / Hernioplasty with laparoscopy mesh application in equine with incisional hernia

Background: Incisional hernia in the midline can be a consequence of abdominal surgeries, which incidence is around5.7-18%. Surgical indication occurs in cases of large hernias, and the most common techniques used involve the closingof the musculature in a primary way, with sutures, and the implantation of a mesh on the abdominal wall. Laparoscopichernioplasty emerged as a less invasive option, showing superiority when compared with open surgical techniques in human medicine, however there are few reports describing this technique in equines. So, the aim of this paper is to report acase of hernioplasty, using laparoscopic mesh, in a horse with midline incisional hernia.Case: A 13-year-old castrated male Brasileiro de Hipismo horse, weighing 415 kg, practitioner of classic equestrian, presented an incisional hernia after 14 days from an exploratory laparotomy surgery realized to treat colic syndrome. After 6months, the patient was referred to a Veterinary Medicine Teaching Hospital for the correction of the defect in the abdominal wall. During palpation, the animal did not present local pain or other sign of inflammation, and the hernia measuredapproximately 20 cm in diameter. The animal was submitted to general anesthesia and placed in dorsal decubitus for thehernioplasty surgical procedure. An incision was made in cranial region of the midline, close to the xiphoid to introduce asingle port; the abdomen was inflated with CO2 gas (12 mmHg) and the operating table was tilted in order to displace theorgans cranially, facilitating the laparoscopic procedure. The abdomen was inspected and the presence of a single adherence could be observed, which was disrupted with endoscopic forceps. The mesh was introduced through the single port...(AU)

Diagnóstico e tratamento videoassistido de tumor de células de Leydig em cadela com síndrome do ovário remanescente / Videoassisted diagnosis and treatment for Leydig cell tumor in a bitch with remaining ovary syndrome

Neoplasias ovarianas de origem primária são incomuns em cadelas, exigindo métodos diagnósticos e terapêuticos mais precisos. Fêmeas também possuem células intersticiais secretoras de esteróides, contudo o aparecimento do tumor de células de Leydig é considerado raro. Uma cadela sem raça definida e 12 anos apresentava sinais de estro após ovariohisterectomia pré-púbere. Na avaliação ultrassonográfica, foi identificada uma massa localizada na região abdominal lateral direita, sugestiva de ovário remanescente. Durante a inspeção laparoscópica foi identificada a massa distante caudalmente do coto ovariano direito, inserida em região de mesentério jejunal. O segmento intestinal foi apreendido e exteriorizado de maneira videoassistida, optando-se pela remoção do tumor associado à enterectomia do segmento afetado. A avaliação do coto ovariano esquerdo, revelou um cisto de 0,5cm de diâmetro que também foi removido. A análise histopatológica foi sugestiva de neoplasia de células intersticiais (tumor de células de Leydig) e um cisto epitelial ovariano. O tumor de células de Leydig é relatado com freqüência em machos, entretanto, sua aparição em fêmeas é considerada extremamente incomum acometendo principalmente animais não esterilizados. A neoplasia não aderida ao coto ovariano comprova ainda que resquícios de tecido ovariano que porventura fiquem livres na cavidade abdominal podem ser responsáveis pelo desenvolvimento da síndrome do ovário remanescente e neoplasias. O prognóstico para neoplasias ovarianas sem metástases é favorável, principalmente quando aplicada a intervenção cirúrgica como método terapêutico. O uso da videocirurgia para auxiliar no diagnóstico e tratamento demonstrou-se adequado para o caso descrito, mas que deve ser complementado pela análise histopatológica.

Primary ovarian neoplasms are uncommon in bitches, requiring more accurate diagnostic and therapeutic methods. Females also have steroid-secreting interstitial cells, however, the appearance of the Leydig cell tumor is considered rare. A 12-year-old mongrel bitch showed signs of estrus after prepubertal ovariohysterectomy. Ultrasound evaluation located a mass in the right lateral abdominal region, suggestive of a remaining ovary. During laparoscopic exploration, the mass was identified caudally distant from the right ovarian stump, adhered to the jejunal mesentery. The intestinal segment was apprehended and exteriorized by video-assisted technique, and removal of the tumor was performed associated with enterectomy of the affected segment. Evaluation of the left ovarian stump revealed a 0.5cm diameter cyst that was also removed. Histopathological analysis was suggestive of interstitial cell neoplasia (Leydig cell tumor) and an ovarian epithelial cyst. The Leydig cell tumor is frequently related in males, however, its appearance in bitches is considered uncommon, affecting mainly nonsterile animals. The mass non-adhered to the ovarian stump proves that remnants of ovarian tissue that may be free in the abdominal cavity and may be responsible for the development of the remaining ovary syndrome and neoplasms. The prognosis for ovarian neoplasms without metastasis is favorable, especially when surgical intervention is applied as a therapeutic method. The use of video surgery to assist in the diagnosis and treatment was considered appropriate for the case described, but it must be complemented by histopathological analysis.

Simulation in Pediatric Video Surgery: Training with Simple and Reproducible Exercises Elaborated by Residents.

Background: Most residents do not have a defined program for simulation training in video surgery in Brazil. The training takes place for the most part in vivo or in short courses. The goal of this article is to describe and evaluate a set of exercises using low-cost materials, created by the residents themselves, to enable basic skills training in video surgery. Materials and Methods: Seven exercises were elaborated aiming to simulate main maneuvers performed in video surgery. The residents were guided by a written and video description showing the execution of the exercises, performed the exercises, and answered a questionnaire. After 3 weeks of free training, the residents performed the exercises and answered the questionnaire again. Results: Seven residents started the study; however, 6 completed the two steps. Among the participants, 83% received in vivo video surgery training, and only 2 (33%) received some supervised simulation training in minimally invasive surgery before this time. All participants considered the set of seven exercises representative of the actual skills in video surgery. There was no difficulty in acquiring the materials or in assembling them to carry out the training. All the participants had a shorter training time than initially proposed, on average 1 day/week for 20 minutes. Conclusions: A simple set of exercises can be elaborated by the residents themselves and make feasible the simulated training in video surgery even without the availability of sophisticated and expensive materials. The presence of a tutor and the scheduling of exclusive training seem necessary for more satisfactory results.

Behavioural and physiological effects of methadone in the perioperative period on the Nile tilapia Oreochromis niloticus.

Through the analysis of behavioural changes, this study demonstrates that methadone has behavioural, but not analgesic, effects on Oreochromis niloticus. It provides information that suggests the drug has sedative abilities, as the recovery time was shorter in the fish receiving methadone. Future research, with different doses and stimuli, is required to provide more information about analgesia.

Resection of a giant nonparasitic splenic cyst by minilaparoscopy.

A female patient, 20 years old, with a history of a progressive increase in abdominal volume on the left side, starting 3 years ago, with no associated symptoms and no history of trauma. Ultrasonography and a computed tomography scan of the abdomen were performed, which revealed a large splenomegaly, and a partial minilaparoscopic splenectomy was indicated. We opted for unroofing of the cyst, and the procedure was uneventful, with a total surgical time of 47 min. The patient progressed clinically well, without abdominal pain, being discharged on the 2nd post-operative day.

Lung biopsy with guillotine cutting needle and biopsy forceps though transdiaphragmatic thoracoscopy in dogs with pulmonary alterations / Biópsia pulmonar com agulha cortante guilhotinada e pinça de biopsia por toracoscopia transdiafragmática em cães com alterações pulmonares

Lung diseases are common in small animal clinical routine. Diagnosis is usually affected due to nonspecific symptoms. Imaging features such as radiography and chest ultrasound are acceptable screening tests, although lung biopsy can provides a precise diagnosis. Thus thoracoscopy provides a minimally invasive diagnostic assessment for chest diseases and offers the benefits such as improved illumination and magnification of the image when compared with thoracotomy. In this study we evaluated the transdiaphragmatic thoracoscopic-assisted techniques of lung biopsy with a the guillotine cutting needle and biopsy forceps, in dogs presenting radiographic suspicion on pulmonary tumors. Fourteen dogs regardless of breed, gender, age and body weight admitted at the Hospital of Veterinary Clinics (HCV) of the Veterinary College (FAVET) of Universidade Federal do Rio Grande do Sul (UFRGS), were assessed. Inclusion criteria were presence of nodules on chest radiography and triage tests without changes that could hinder general anesthesia and surgical approach. The animals were positioned in dorsal recumbence and two thoracoscopic ports were established: the first port for working instruments; the second paraxyphoid port for the telescope. Three samples were collected using each sampling method from each lesion or from tumors macroscopically similar whenever their size was less than one centimeter. The samples were sent for histopathological examination in the Veterinary Pathology Laboratory of FAVET/UFRGS. Surgical time was recorded from first incision to wound closure and surgical complications were reported. The dogs were evaluated for the presence of subcutaneous emphysema, hematoma, seroma, local infection and dehiscence. No conversion to open surgery was necessary during the thoracoscopic procedure in any patient. Thoracoscopic assisted biopsy using guillotine needle and biopsy forceps was a safe and fast technique, without perioperative complications...(AU)

As afecções pulmonares são comuns na rotina clínica de pequenos animais, todavia, por apresentarem sintomas inespecíficos, muitas vezes o diagnóstico dessas doenças torna-se limitado. Recursos de imagem como a radiografia e a ultrassonografia torácica são válidos como exames de triagem, mas somente a biopsia pulmonar pode possibilitar um diagnóstico específico da doença. A toracoscopia fornece um meio minimamente invasivo de diagnóstico para as doenças torácicas e oferece os benefícios de melhor iluminação e ampliação da imagem, quando comparado com a toracotomia. O presente estudo teve como objetivo avaliar as técnicas de biópsia pulmonar por meio da agulha cortante guilhotinada e da pinça de biopsia, guiadas por toracoscopia, pelo acesso transdiafragmático em cães que apresentavam imagem sugestiva de nódulo pulmonar em exame radiográfico prévio. Foram utilizados 14 cães, independente de raça, sexo, idade e peso corporal. Somente caninos com nódulos visíveis na radiografia torácica e que apresentaram condições clínicas e laboratoriais de serem anestesiados foram incluídos no estudo. Os cães foram posicionados em decúbito dorsal e foram realizados dois acessos à cavidade torácica: um primeiro portal intercostal, para introdução dos dispositivos de biopsia; e outro portal paraxifoide transdiafragmático para introdução do endoscópio. Com cada instrumento de biopsia foram coletadas três amostras do mesmo nódulo ou de nódulos macroscopicamente semelhantes e próximos quando o tamanho destes era inferior a um centímetro. Posteriormente as amostras foram encaminhadas para exame histopatológico. O tempo cirúrgico foi cronometrado da incisão ao fechamento da ferida, e todas as informações foram registradas. No pós-operatório os cães foram avaliados quanto à presença de enfisema subcutâneo, hematoma, seroma, infecção local e deiscência de pontos. Não foi necessário converter os procedimentos toracoscópicos para cirurgia convencional em nenhum dos caninos...(AU)

Thoracoscopic assisted biopsy using guillotine needle and biopsy forceps was a safe and fast technique, without perioperative complications. Both devices provided good quality samples for histopathological analysis of lung abnormalities. However the cutting guillotine needle was more efficient especially in larger pulmonary nodules. The transdiaphragmatic access provided optimal approach for both hemithoraces.(AU)

Evaluation of ventral laparoscopic abomasopexy using surgical staples associated with suture material in dairy cattle

Background: Displaced Abomasum is known for being on of the main illnesses that affect milking cows. Increase in diagnosis of this illness is due to advancement in diagnosis techniques. Increase in incidence of this illness can be explained by genetic selection of animals with high production, breed systems and changes to the diet with a higher level of protein. For laparoscopic treatment, several surgical changes were performed to optimize the procedure and thus achieve better results. The main purpose of this study was to evaluate applicability of the ventral laparoscopic abomasopexy technique, using surgical clamps attached to the suture thread, to milking cows.Materials, Methods & Results: Six adult cows were placed under anesthesia with isoflurane and placed in dorsal decubitus. Animals were kept with no water for 24 h and no food for 48 h. Four laparoscopic accesses were performed. The first one was created with the intention of inspecting the abdominal cavity and the remaining three for access of surgical instruments. Serous membrane of the abomasum was cauterized, combined with suture threads and placed at the greater abomasal curvature. The free part of suture threads was kept out of the abdominal cavity and after traction of the abomasum against the abdominal wall was tied to the skin. Ultrasound exam was performed for abdominal evaluation after abomasopexy. Anesthesia time and surgery time were recorded and analyzes through average and standard deviation (SD). The average anesthesia time recorded was 94 min (SD 14.63 min) and average surgery time was 51 min (SD 14.71 min). The fasting period was considered adequate, however all animals had to undergo intubation with orogastric tube to drain liquids and gas during the procedure. Four of the six animals had lineal adhesion. Three of the four animals that had adhesion did not keep the abomasum at the retroperitoneal area, however viscera movement was stopped in the abdominal cavity.[...]

Ocorrência e fatores de risco de infecção de sítio cirúrgico em colecistectomia videolaparoscópica / Occurrence and risk factors of surgical site infection in laparoscopic cholecystectomy

A infecção de sítio cirúrgico (ISC) é uma complicação que pode acometer o paciente, acarretando incremento da mortalidade e morbidade, bem como aumento dos custos em saúde. A videocirurgia surgiu como opção menos invasiva de acesso à cavidade abdominal, reduzindo as taxas de ISC, mas nem mesmo a modernização gerada pela cirurgia minimamente invasiva conseguiu extinguir esse tipo de infecção. O presente estudo teve como objetivo geral analisar a ocorrência e os fatores de risco de infecção de sítio cirúrgico, em pacientes submetidos à colecistectomia videolaparoscópica. Trata-se de estudo descritivo exploratório conduzido em hospital de pequeno porte, localizado no sudoeste de Minas Gerais. A amostra foi composta por 118 pacientes. Para a coleta de dados, elaborou-se instrumento, o qual foi submetido à validação de face e conteúdo por estudiosos da área de conhecimento de enfermagem perioperatória. A coleta dos dados foi realizada no período de março a novembro de 2016 e, em três momentos, a saber: perioperatório, retorno ambulatorial e busca ativa fonada. Os dados foram coletados pelo pesquisador e um auxiliar de pesquisa devidamente treinados. A ocorrência de ISC foi de 5,9% (n=7), sendo todos os casos diagnosticados como infecção incisional superficial. As variáveis investigadas relacionadas ao paciente foram sexo, faixa etária, Índice de Massa Corporal, presença de doença crônica e classificação ASA. As variáveis estudadas relacionadas ao procedimento anestésico-cirúrgico foram tempo total de internação, porte cirúrgico, tempo de anestesia e tempo de cirurgia. Os resultados não apresentaram diferença estatisticamente entre as variáveis de interesse e a presença de ISC. Todos os casos de ISC foram diagnosticados, após a alta hospitalar, desses, seis pacientes (86%) tiveram o diagnóstico no retorno ambulatorial, e um paciente (14%) foi diagnosticado durante a busca ativa fonada. A condução do estudo oferece subsídios para a compreensão da problemática, no âmbito nacional. Além disso, gerou evidências para a reflexão dos profissionais de saúde em relação à subnotificação desse tipo de infecção em cirurgia minimamente invasiva, reforçando a necessidade de implantação de programa de vigilância pós-alta, nos serviços de saúde

Surgical site infection (SSI) is a complication that can affect the patient, leading to an increase in mortality and morbidity, as well as an increase in health costs. Video surgery emerged as a less invasive option for access to the abdominal cavity, reducing SSI rates; however, not even the improvement generated by minimally invasive surgery was enough to eliminate this type of infection. This study aimed to analyze the occurrence and risk factors of surgical site infection in patients submitted to laparoscopic cholecystectomy. It is an exploratory-descriptive study conducted in a small hospital, located in the southwest of Minas Gerais. The sample consisted of 118 patients. An instrument was developed for data collection, which was submitted to face and content validation by experts in perioperative nursing. Data collection was performed from March to November 2016 and, in three stages: perioperative, outpatient return and active phone search. Data were collected by the researcher and a properly trained research assistant. The occurrence of SSI was 5.9% (n=7), being all cases diagnosed as superficial incisional infection. The studied variables related to the patient were gender, age, Body Mass Index, presence of chronic disease and ASA classification. The studied variables related to the anesthetic surgical procedure were total length of hospitalization, surgical procedure size, time of anesthesia and time of surgery. The results did not show statistically difference between the variables of interest and the presence of SSI. All cases of SSI were diagnosed after patient discharge, and among them, six patients (86%) were diagnosed during outpatient return, and one patient (14%) was diagnosed during the active phone search. This study offers subsidies for understanding the problem at national level. In addition, it generated evidence for the reflection of health professionals regarding the underreporting of this type of infection in minimally invasive surgery, reinforcing the need to implement a post-discharge surveillance program in health services

Ocorrência e fatores de risco de infecção de sítio cirúrgico em colecistectomia videolaparoscópica / Occurrence and risk factors of surgical site infection in laparoscopic cholecystectomy

A infecção de sítio cirúrgico (ISC) é uma complicação que pode acometer o paciente, acarretando incremento da mortalidade e morbidade, bem como aumento dos custos em saúde. A videocirurgia surgiu como opção menos invasiva de acesso à cavidade abdominal, reduzindo as taxas de ISC, mas nem mesmo a modernização gerada pela cirurgia minimamente invasiva conseguiu extinguir esse tipo de infecção. O presente estudo teve como objetivo geral analisar a ocorrência e os fatores de risco de infecção de sítio cirúrgico, em pacientes submetidos à colecistectomia videolaparoscópica. Trata-se de estudo descritivo exploratório conduzido em hospital de pequeno porte, localizado no sudoeste de Minas Gerais. A amostra foi composta por 118 pacientes. Para a coleta de dados, elaborou-se instrumento, o qual foi submetido à validação de face e conteúdo por estudiosos da área de conhecimento de enfermagem perioperatória. A coleta dos dados foi realizada no período de março a novembro de 2016 e, em três momentos, a saber: perioperatório, retorno ambulatorial e busca ativa fonada. Os dados foram coletados pelo pesquisador e um auxiliar de pesquisa devidamente treinados. A ocorrência de ISC foi de 5,9% (n=7), sendo todos os casos diagnosticados como infecção incisional superficial. As variáveis investigadas relacionadas ao paciente foram sexo, faixa etária, Índice de Massa Corporal, presença de doença crônica e classificação ASA. As variáveis estudadas relacionadas ao procedimento anestésico-cirúrgico foram tempo total de internação, porte cirúrgico, tempo de anestesia e tempo de cirurgia. Os resultados não apresentaram diferença estatisticamente entre as variáveis de interesse e a presença de ISC. Todos os casos de ISC foram diagnosticados, após a alta hospitalar, desses, seis pacientes (86%) tiveram o diagnóstico no retorno ambulatorial, e um paciente (14%) foi diagnosticado durante a busca ativa fonada. A condução do estudo oferece subsídios para a compreensão da problemática, no âmbito nacional. Além disso, gerou evidências para a reflexão dos profissionais de saúde em relação à subnotificação desse tipo de infecção em cirurgia minimamente invasiva, reforçando a necessidade de implantação de programa de vigilância pós-alta, nos serviços de saúde

Surgical site infection (SSI) is a complication that can affect the patient, leading to an increase in mortality and morbidity, as well as an increase in health costs. Video surgery emerged as a less invasive option for access to the abdominal cavity, reducing SSI rates; however, not even the improvement generated by minimally invasive surgery was enough to eliminate this type of infection. This study aimed to analyze the occurrence and risk factors of surgical site infection in patients submitted to laparoscopic cholecystectomy. It is an exploratory-descriptive study conducted in a small hospital, located in the southwest of Minas Gerais. The sample consisted of 118 patients. An instrument was developed for data collection, which was submitted to face and content validation by experts in perioperative nursing. Data collection was performed from March to November 2016 and, in three stages: perioperative, outpatient return and active phone search. Data were collected by the researcher and a properly trained research assistant. The occurrence of SSI was 5.9% (n=7), being all cases diagnosed as superficial incisional infection. The studied variables related to the patient were gender, age, Body Mass Index, presence of chronic disease and ASA classification. The studied variables related to the anesthetic surgical procedure were total length of hospitalization, surgical procedure size, time of anesthesia and time of surgery. The results did not show statistically difference between the variables of interest and the presence of SSI. All cases of SSI were diagnosed after patient discharge, and among them, six patients (86%) were diagnosed during outpatient return, and one patient (14%) was diagnosed during the active phone search. This study offers subsidies for understanding the problem at national level. In addition, it generated evidence for the reflection of health professionals regarding the underreporting of this type of infection in minimally invasive surgery, reinforcing the need to implement a post-discharge surveillance program in health services

Cervical and transdiaphragmatic paraxiphoid thoracoscopy in dogs: evaluation of respiratory response and blood pressure / Toracoscopias cervical e paraxifóide transdiafragmática em cães: aplicação de técnica e avaliação da resposta respiratória e pressão sanguínea

This study evaluated the cervical and transdiaphragmatic thoracoscopic approaches regarding their implementation, intrathoracic evaluation and application of a chest tube, using the treatment of pneumothorax as an experimental model. After injection of 20ml kg-1 of air per hemithorax, thoracoscopy was made by transdiaphragmatic paraxiphoid or cervical positions. After cavity examination, a thoracic drain was inserted using the surgical site to drain the pneumothorax. The cardiorespiratory function and arterial blood gas were measured during time of evaluation. The cavity examination allowed visualizing the aspect and function of intrathoracic structures. There were no significant differences between the two approaches when comparing the measurements made in each period evaluated. Both enabled intracavitary exploration and application of thoracic drain. Cervical access shows viability, but resulted in the death of two patients, and it not recommended as a substitute for the latter in the insertion of thoracic drains in dogs.(AU)

Este estudo avaliou os acessos toracoscópicos cervical e paraxifóide em relação à sua aplicação, avaliação intratorácica e colocação de dreno torácico, utilizando o tratamento de pneumotórax como modelo experimental. Após a injeção de 20ml kg-1 de ar por hemitórax, a toracoscopia foi realizada pelas técnicas cervical ou paraxifóide transdiafragmática. Após a exploração da cavidade, foi inserido um dreno torácico utilizando o acesso cirúrgico para drenar o pneumotórax. A função cardiorrespiratória e a gasometria arterial foram aferidas durante o tempo de avaliação. A exploração da cavidade permitiu visualização do aspecto e função das estruturas intratorácicas. Não houve diferenças significativas entre os dois acessos quanto aos dados aferidos em cada período de avaliação. Ambos permitiram exploração intracavitária e aplicação do dreno torácico. O acesso cervical demonstra viabilidade, porém resultou na morte de dois pacientes, e não é recomendado como substituta à paraxifóide transdiafragmática para a aplicação de drenos torácicos em cães.(AU)

Ovariohisterectomia videoassistida com dois portais para o tratamento de piometra em cadela

This report describes pyometra's treatment in a bitch which was submitted to video-assisted ovariohysterectomy by two portals. The approach into abdominal cavity was carried through two midline incisions of 1cm each, and the ovaries fixed in the abdominal wall by a transcutaneous suspension suture and after the identification of the vascular bed, titanium clips were placed for hemostasis with subsequent section of the ovarian stumps. The pre-pubic incision had to be enlarged to remove the ovaries and uterine horns, ligating the uterine body externally by the conventional technique. The video-assisted treatment of pyometra with two portals was performed in able surgical time when compared with similar procedures described, without complications and minimal blood loss.

O presente trabalho descreve o tratamento de piometra em uma cadela submetida à ovariohisterectomia videoassistida por meio de dois portais. O acesso da cavidade abdominal ocorreu através de duas incisões de 1cm em linha média, sendo os ovários fixados na parede abdominal por um reparo transcutâneo e, após a visualização do leito vascular, iniciou-se a colocação de clipes de titânio para hemostasia com posterior secção dos cotos ovarianos. A incisão pré-púbica foi ampliada, sendo os ovários e útero exteriorizados e o corpo uterino ligado pelo método convencional de pediculação. O tratamento de piometra videoassistido com dois portais foi realizado em tempo cirúrgico hábil, quando comparado aos observados em procedimentos laparoscópicos na literatura, sem complicações e com perda sanguínea mínima.
