Curva de aprendizaje para el acceso con trocar óptico en cirugía pélvica laparoscópica: estudio prospectivo / Learning curve of optical trocar access during laparoscopic pelvic surgery: A prospective study

Introducción El acceso con trocar óptico (ATO) es una técnica modificada de laparoscopia cerrada cuyo objetivo es minimizar el riesgo de lesiones vasculares o intestinales y reducir la posible fuga de gas. Se ha analizado el efecto de la curva de aprendizaje (CA) para el ATO, considerando n=30 procedimientos como umbral para definir un nivel aceptable de experticia. Nuestro objetivo es evaluar el impacto de la CA en los primeros 30 casos de ATO realizados por un aprendiz. Métodos Se trata de un estudio prospectivo aleatorizado en 60 pacientes planificadas para cirugía ginecológica laparoscópica. Las pacientes fueron seleccionadas aleatoriamente para el ATO realizado por un cirujano sin entrenamiento previo en la técnica o por un cirujano experto. La CA se evaluó mediante: 1) tiempo hasta lograr el acceso; 2) número de correcciones hechas por el experto; 3) número de veces en que la punta del trocar se detuvo en la capa preperitoneal; 4) errores al realizar la incisión en la piel; 5) veces en que la punta del trocar termina bajo el epiplón; 6) complicaciones. Para analizar el CA en los 30 primeros casos, se estratificaron los procedimientos en 3 grupos (casos 1-10; 11-20; 21-30) tanto para el aprendiz como para el experto y se compararon las variables de la CA. Resultados De forma global, el tiempo medio de inserción para el ATO fue de 56s. No se registraron complicaciones intraoperatorias ni postoperatorias graves. El tiempo medio de inserción fue estadísticamente más largo para el aprendiz en comparación con el experto en los 10 primeros casos (91s frente a 33s, respectivamente, p=0,01). En los casos 11-20 y 21-30, la ventaja de tiempo del cirujano experto se hizo menos evidente (p=0,05). El número de veces que la punta del trocar se detuvo en la capa preperitoneal fue similar entre los grupos, así como las veces que la punta del trocar llegó por debajo del epiplón. Conclusiones La técnica de ATO es rápida y reproducible . ... (AU)

Introduction The optical trocar access (OTA) is a modified closed technique that aims to minimize the risk of vascular or bowel injuries while reducing the likelihood of gas leakage. A learning curve (LC) effect for OTA has been invoked with n=30 procedures being considered as a threshold to define expertise. We aim to evaluate the impact of the LC within the first thirty cases of OTA performed by a trainee. Methods This is a prospective randomized study on 60 patients elected to laparoscopic gynecological surgery. Patients were randomized to have OTA insertion by a junior surgeon or by an expert. LC was evaluated by: 1) insertion time; number of: 2) corrections by the senior; 3) times the tip of the trocar stopped in the preperitoneal layer; 4) mistakes of skin incision; 5) times the tip of the trocar ends under the omentum; 6) complications. To analyze the LC within the first 30 cases, procedures were stratified in 3 groups (cases 1-10; 11-20; 21-30) for both trainee and expert and LC variables were compared. Results Overall, mean OTA insertion time was 56s. No major intra- and post-operative complications were recorded. Mean insertion time was statistically significantly longer for the trainee compared to the expert within the first 10 cases (91 vs 33s respectively, p=0.01). For cases 11-20 and 21-30, time advantage of the senior surgeon is less evident (p=0.05). The number of times the tip of the trocar stopped in the preperitoneal layer was similar between groups, as well as times the tip of the trocar ends under the omentum. Conclusions OTA is a fast and simple way to achieve the pneumoperitoneum and first trocar insertion as a single step. The current series confirms the effectiveness of the technique since the beginning of the LC. (AU)

Nurses' role in the management of persons with chronic urogenital pelvic pain syndromes: A scoping review.

BACKGROUND: Pelvic pain has cognitive, behavioral, sexual, and emotional consequences. Nurses involved in pelvic floor rehabilitation clinics have contacts with patients reporting chronic pain and should know the most appropriate service for patient referral, to submit the problem to professionals capable of correctly assessing and managing the condition. Furthermore, in some countries nurses can use conservative methods to treat the painful symptoms inside a multidisciplinary team such as breathing retraining, biofeedback, and noninvasive neuromodulation. This paper aims to provide an overview of the literature regarding the role of rehabilitation nurses in dealing with patients suffering from chronic urogenital pelvic pain or urogenital painful syndromes, inside a multidisciplinary team. METHODS: Scoping review on Pubmed, CINAHL, Embase, Scopus, Web of Science including trials, reviews, case studies or series, and other descriptive studies regarding the role of nurses inside the multidisciplinary team in the management of males and females presenting chronic pelvic pain (CPP) or chronic pelvic pain syndrome (CPPS). RESULTS: The 36 papers included in this review allowed answering research questions in four areas of nursing: collecting basic information, referring the person to appropriate services, evidence-based nursing interventions for CPP and CPPS, and proper documentation. Clinical history and assessment of breathing pattern, Muscular assessment and research of trigger points are the main points of data collection. Techniques for muscular relaxation and breathing retraining are important aspects of treatment, as well as biofeedback and noninvasive neuromodulation where the law allows nurses to practice such techniques. The McGill pain questionnaire and the pain inventory of the International Pain Society allow systematic data collection and handover. CONCLUSION: Rehabilitation nurses work inside multidisciplinary teams when dealing with persons suffering from pelvic pain; further research is needed as our comprehension of the underlying pathophysiological mechanisms of CPP and CPPS evolve.

Robotic multiple sigmoid and rectal mucosa skinning in a multicentric deep infiltrating bowel endometriotic nodules: a case report

Endometriosis is a benign gynecological disease characterized by the presence of endometrial tissue outside the uterus. The eradication of non-gynecological localizations represents the real surgical challenge. A 29-year-old woman underwent robotic surgery with the Da Vinci system (Intuitive Surgical Inc.) for a diagnosis of stage IV deep endometriosis.The patient presented with 5 cm left ovarian endometrioma, an infiltration of the left posterior parametrium, and bilateral ureteral endometriosis. Once inside the pelvic cavity, deep intestinal infiltrating endometriosis implants were confirmed as triple, multicentric, and multifocal lesions, affected distal sigmoid, rectosigmoid junction, and upper rectum. An expert multiple excision, sparing the intestinal mucosa, was performed. To our knowledge, this is the first description of a multiple robotic shaving of multicentric endometriotic intestinal lesions. After the surgery, a normal diet was quickly restored, accelerating the recovery of the physiological peristalsis and the overall recovery time.

The Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration Project: Development of Criteria for Reporting Adverse Events During Surgical Procedures and Evaluating Their Impact on the Postoperative Course.

BACKGROUND: Intraoperative adverse events (iAEs) are surgical and anesthesiologic complications. Despite the availability of grading criteria, iAEs are infrequently reported in the surgical literature and in cases for which iAEs are reported, these events are described with significant heterogeneity. OBJECTIVE: To develop Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration criteria to standardize the assessment, reporting, and grading of iAEs. The ultimate aim is to improve our understanding of the nature and frequency of iAEs and our ability to counsel patients regarding surgical procedures. DESIGN, SETTING, AND PARTICIPANTS: The present study involved the following steps: (1) collecting criteria for assessing, reporting, and grading of iAEs via a comprehensive umbrella review; (2) collecting additional criteria via a survey of a panel of experienced surgeons (first round of a modified Delphi survey); (3) creating a comprehensive list of reporting criteria; (4) combining criteria acquired in the first two steps; and (5) establishing a consensus on clinical and quality assessment utility as determined in the second round of the Delphi survey. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Panel inter-rater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS AND LIMITATIONS: The umbrella review led to nine common criteria for assessing, grading, and reporting iAEs, and review of iAE grading systems led to two additional criteria. In the first Delphi round, 35 surgeons responded and two criteria were added. In the second Delphi round, 13 common criteria met the threshold for final guideline inclusion. All 13 criteria achieved the consensus minimum of 70%, with agreement on the usefulness of the criteria for clinical and quality improvement ranging from 74% to 100%. The mean inter-rater agreement was 89.0% for clinical improvement and 88.6% for quality improvement. CONCLUSIONS: The ICARUS Global Collaboration criteria might aid in identifying important criteria when reporting iAEs, which will support all those involved in patient care and scientific publishing. PATIENT SUMMARY: We consulted a panel of experienced surgeons to develop a set of guidelines for academic surgeons to follow when publishing surgical studies. The surgeon panel proposed a list of 13 criteria that may improve global understanding of complications during specific procedures and thus improve the ability to counsel patients on surgical risk.
