Effect of laparoscopic handle size on surgical performance: A randomized crossover trial.

Laparoscopic instrument handles design and dimensions are crucial to determine the configuration of surgeons' hand grip and, therefore, can have a deleterious effect on overall surgical efficiency and surgeons' comfort. The aim of this study is to investigate the impact of laparoscopic handle size and hand surface area on surgical task performance. A single-blind, randomized crossover trial was carried out with 29 novice medical students. Participants performed three simulated tasks in "black box" simulators using two scissor-type handles of different sizes. Surgical performance was assessed by the number of errors and time required to complete each task. Hand anthropometric data were measured using a 3D scanner. Execution time was significantly higher when cutting and suturing tasks were performed with the smaller handle. In addition, hand surface area was positively correlated with peg transfer task time when performed with the standard handle and was correlated with cutting task time in small and standard handle groups. We also found positive correlations between execution time and the number of errors executed by larger-handed participants. Our findings indicate that laparoscopic handle size and hand area influence surgical performance, highlighting the importance of considering hand anthropometry variances in surgical instrument design.

Epidemiological and clinical assessment of patients undergoing Videolaparoscopic Cholecystectomy at a Curitiba teaching hospital. / Análise do perfil clínico epidemiológico dos pacientes submetidos a Colecistectomia Videolaparoscópica em um hospital de ensino de Curitiba.

OBJECTIVE: to assess clinical and epidemiological factors of patients undergoing video cholecystectomy at the Hospital da Cruz Vermelha do Paraná, Curitiba unit, operated from September 2016 to September 2018, as well as the influence of comorbidities, sex and advanced age on the postoperative prognosis, while in the hospital. METHODS: Analytic retrospective study. The analyzed variables were obtained by the review of medical records. Statistical analyses were performed considering the significance level p < 0.05. RESULTS: 389 patients, of whom 265 were women and 124 men, were included. The mean age was 51.5 years, 58.8% of the patients were diagnosed with at least one comorbidity, and 74.6% were overweight or obese. The incidence of intraoperative complications was 1.3%, postoperative 3.8% and, mortality, 0.3%. Some risk factors were identified as worse postoperative prognosis, such as Diabetes Mellitus, hypertension, presence of one or more comorbidities and mainly, advanced age, which was related to longer hospitalization times (p < 0,001), need of intensive therapy (p < 0,001), conversion to open surgery (p = 0,003) and postoperative complications (p < 0,001). Furthermore, the male sex was predictive of longer hospitalization times (p = 0,003) and need of intensive therapy (p = 0,01). CONCLUSION: the presence of comorbidities, male sex, and advanced age are predictive factors of bad prognosis for patients undergoing video laparoscopic cholecystectomy.

OBJETIVO: Analisar o perfil clínico e epidemiológico de pacientes submetidos a colecistectomia por vídeo no Hospital da Cruz Vermelha do Paraná, unidade de Curitiba, operados no período de setembro de 2016 a setembro de 2018, assim como a influência de comorbidades, sexo e idade avançada no prognóstico pós-operatório, durante o mesmo internamento. MÉTODOS: Estudo retrospectivo analítico, com dados coletados por revisão de prontuários. Análises estatísticas realizadas, considerando nível de significância p < 0,05. RESULTADOS: 389 casos foram incluídos, sendo 265 mulheres e 124 homens. A média de idade foi de 51,5 anos, 58,8% dos pacientes eram portadores de pelo menos uma comorbidade e 74,6% dos doentes tinham sobrepeso ou eram obesos. A incidência de complicações intraoperatórias foi de 1,3%, pós-operatórias de 3,8% e, a mortalidade, de 0,3%. Foram identificados fatores clínicos relacionados a pior prognóstico pós-operatório, como DM, HAS, presença de uma ou mais comorbidades e, destacadamente, idade avançada, que relacionou-se com maior tempo de internamento (p < 0,001), necessidade de UTI (p < 0,001), conversão para operação aberta (p = 0,003) e risco de complicações pós-operatórias (p < 0,001). Além disso, o sexo masculino foi preditivo para maior tempo de internamento (p = 0,003) e maior necessidade de UTI (p = 0,01). CONCLUSÃO: o perfil clínico-epidemiológico corresponde àquele exposto na literatura e a presença de comorbidades, o sexo masculino e a idade avançada são fatores preditivos de mau prognóstico na evolução pós-operatória de pacientes submetidos a colecistectomia videolaparoscópica.

Complicações referentes à correção videolaparoscópica de hérnia inguinal: um estudo comparativo entre as técnicas TEP e TAPP realizado em um hospital terciário / Complications related to inguinal hernia videolaparoscopic repair: a comparative study between TEP and TAPP techniques in a terciary hospital

Hérnias de parede abdominal estão entre as enfermidades mais comuns na prática cirúrgica. Atualmente, duas técnicas videolaparoscópicas são utilizadas: totalmente extraperitoneal (TEP) e transabdominal pré-peritoneal (TAPP). Este estudo busca descrever e comparar as características clínico-epidemiológicas dos pacientes submetidos a herniorrafia videolaparoscópica por essas técnicas Para tal, foram analisados prontuários de pacientes atendidos no serviço de cirurgia geral do Hospital Cruz Vermelha Brasileira - Curitiba, entre novembro de 2009 e dezembro de 2018. Trata-se de um estudo transversal analítico com coleta de dados retrospectiva. Os dados evidenciaram uma prevalência em homens, idade média de 50 anos e hérnia inguinal à direita. Quando comparadas, não houve associação entre frequência de complicações e técnica utilizada. Hérnias que acometem o lado esquerdo, tendem a recidivar com maior frequência. O estudo reforça a recomendação da literatura: a técnica preferencial deve ser escolhida conforme experiência do cirurgião.

Abdominal wall hernias are among the most common diseases in surgical practice. Currently, two videolaparoscopic techniques are used: totally extraperitoneal (TEP) and pre-peritoneal transabdominal (TAPP). This study aims to describe and quantify the clinical and epidemiological characteristics of patients submitted to videolaparoscopic herniorrhaphy by these techniques, in order to identify which is the preferred one. For that, charts from patients who underwent treatment in the general surgery service of the Brazilian Red Cross Hospital - Curitiba, during November 2009 and February 2018, were analyzed. This is a cross-sectional analytical study with retrospective data collection. The data showed a prevalence of men, mean age of 50 years and right inguinal hernia. When compared, there was no association between the frequency of complications and the technique used. Hernias that affect the left side tend to recur more frequently. The study reinforces the recommendation of the literature: the preferred technique should be chosen according to the experience of the surgeon.

Uterine transposition: technique and a case report.

OBJECTIVE: To report the first uterine transposition for fertility preservation in a patient with rectal cancer. DESIGN: Case report. SETTING: Community hospital. PATIENT(S): A 26-year-old patient with stage cT3N1M0 rectal adenocarcinoma located 5 cm from the anal margin. INTERVENTION(S): Laparoscopic transposition of the uterus to the upper abdomen, outside of the scope of radiation, was performed to preserve fertility. After the end of radiotherapy, rectosigmoidectomy was performed and the uterus was repositioned into the pelvis. MAIN OUTCOME MEASURE(S): Uterine and ovarian function preservation. RESULT(S): The patient had two menstrual periods and exhibited normal variation in ovarian hormones throughout the course of neoadjuvant therapy. Menstruation began 2 weeks after reimplantation into the pelvis, and the cervix exhibited a normal appearance on clinical examination after 6 weeks. Eighteen months after the surgery, the uterus was normal and there was no sign of disease. CONCLUSION(S): Uterine transposition might represent a valid option for fertility preservation in women who require pelvic radiotherapy and want to bear children. However, studies that assess its viability, effectiveness, and safety are required.

Laparoscopic promontofixation for the treatment of recurrent sigmoid neovaginal prolapse: case report and systematic review of the literature.

Prolapse of a sigmoid neovagina, created in patients with congenital vaginal aplasia, is rare. In correcting this condition, preservation of coital function and restoration of the vaginal axis should be of primary interest. A 34-year-old woman with vaginal agenesis underwent vaginoplasty using sigmoid colon. Almost 6 years after the initial operation, she started complaining of a bearing-down sensation and an increase in vaginal discharge. She underwent 2 open surgeries and one vaginal surgery to treat the prolapse with no success. She came to our service and at vaginal examination the neovagina protruded approximately 5 cm beyond the hymen. The prolapse was treated successfully using a laparoscopic approach to suspend the neovagina to the sacral promontory (laparoscopic promontofixation). Prolapse of an artificially created vagina is a rare occurrence, without a standard treatment. Laparoscopy may be an alternative approach to restore the neovagina without compromising its function.
