ABSTRACT

ABSTRACT The current Covid-19 pandemic has been the most discussed topic of the year, mostly about protection and ways to avoid dissemination of the virus. In the healthcare system, especially in the operating rooms, the viability of laparoscopic surgery was questioned, mostly because of the transmission through aerosol. This article tries to suggest a way to minimize risks of laparoscopic surgery, during this situation, by using electrostatic filters, a simple, effective and low cost alternative.


RESUMO A atual pandemia do Covid-19 tem sido o assunto mais discutido do ano de 2020, principalmente no que se refere a proteção e as formas de limitar a disseminação do vírus. No cenário hospitalar, mais especificamente no centro cirúrgico, a viabilidade da cirurgia laparoscópica foi questionada, em relação a transmissibilidade do vírus por aerossol. Este artigo sugere uma forma de minimizar os riscos em cirurgias laparoscópicas durante esse cenário, com o uso de filtros eletrostáticos de ventilação mecânica. Uma alternativa simples, eficaz e de baixo custo.

ABSTRACT

INTRODUCCIÓN: La reciente pandemia por SARS-CoV-2 (COVID-19) ha hecho resurgir preocupación sobre la exposición inadvertida del equipo quirúrgico a agentes infecciosos transmisibles por vía aérea durante el acto quirúrgico. El objetivo de este trabajo es describir la confección de un sistema de filtrado simple y de bajo costo que permite reducir el riesgo de exposición al virus, particularmente en el proceso de aspiración, recambio y remoción del neumoperitoneo en cirugía laparoscópica. MATERIALES Y MÉTODO: Se diseñó e implementó un circuito cerrado de evacuación y de filtrado del neumoperitoneo en cirugías ginecológicas laparoscópicas en un centro de salud terciario. El circuito incluye un filtro HEPA (High Efficiency Particulate Air) y una trampa de vacío que contiene una solución de inactivación en base a amonio cuaternario o hipoclorito de sodio. RESULTADOS: Desde su implementación se han realizado 17 cirugías laparoscópicas ginecológicas por diversas patologías. Dos de ellas fueron en pacientes Covid-19 (+). A la fecha no se han reportado contagios en el equipo médico que participó en la cirugía. CONCLUSIONES: Es posible implementar un sistema de evacuación del neumoperitoneo en cirugía laparoscópica presumiblemente eficaz en minimizar el riesgo de exposición al virus SARS-COV-2 (Covid-19). Su bajo costo lo hace especialmente recomendable en países en vías de desarrollo.


INTRODUCTION: The recent SARS-CoV-2 (COVID-19) pandemics has raised concern on the incidental exposition of health team to air transmissible infectious agents during surgeries. The main goal of this work is to communicate a simple and low-cost filtering system allowing to reduce the risk of contagion related to the virus, associated with pneumoperitoneum removal during surgical laparoscopy. METHODS: A closed circuit of gas removal and filtering was developed and implemented in laparoscopic gynecologic procedures at a tertiary teaching hospital. The circuit included an HEPA (High Efficiency Particulate Air) filter and a vacuum trap containing an inactivating solution based on quaternary ammonium or sodium hypochlorite. RESULTS: Since its introduction, seventeen laparoscopic surgeries have been carried out for different gynecologic pathologies. Two of them in Covid (+) cases. To date, no contagion has been reported among health teammates participating in these surgeries. CONCLUSIONS: It is possible to implement a pneumoperitoneum evacuation system in laparoscopic surgery presumably effective in minimizing the risk of exposure to the SARS-COV-2 virus (Covid-19). Its low cost makes it especially recommended in developing countries.

ABSTRACT

Introducción. La neumatosis intestinal es una condición rara que se caracteriza por la infiltración submucosa o subserosa de gas en el tubo digestivo. Se encuentra más frecuentemente en el intestino delgado y, pocas veces, en localización extraintestinal. Su prevalencia estimada es de 0,03 %.Métodos. Se hizo una búsqueda bibliográfica en las bases de datos biomédicas Medline Pubmed, Science Direct, Tripdatabase y Uptodate, usando como palabras clave 'neumoperitoneo' y 'neumatosis cistoide intestinal' Para la presentación del caso clínico, se tomaron datos de la historia clínica y, además, imágenes de radiografía, tomografías y material fotográfico del procedimiento quirúrgico.Presentación del caso. Se trata de una mujer de 63 años de edad con antecedentes de colagenopatía, que consultó por dolor y distensión abdominal. Aunque no tenía signos de irritación peritoneal, las imágenes diagnósticas revelaron neumoperitoneo y líquido libre en la cavidad peritoneal, por lo que se sospechó una perforación intestinal y se practicó una laparotomía exploratoria, en la cual se encontró neumatosis quística intestinal y peritoneal.Conclusiones. No todos los casos de neumoperitoneo requieren cirugía. Existen casos espontáneos y sin irritación peritoneal, secundarios a neumatosis quística intestinal. En los casos de neumoperitoneo en pacientes estables con un diagnostico etiológico no muy claro, y en quienes se desee descartar perforación intestinal o isquemia mediante exploración quirúrgica, la laparoscopia diagnóstica es una buena opción y menos agresiva que la laparotomía


Introduction: Intestinal pneumatosis is a rare condition that is characterized by submucosal or subserosal gas infiltration in the digestive tract. It is found more frequently in the small intestine, and rarely in an extraintestinal location. Its estimated prevalence is 0.03%.Methods: A literature search was performed in the Medline Pubmed, Sciencedirect, Trip database and Up to date databases, using as keywords Pneumoperitoneum and Intestinal Cystoid Neumatosis. For the presentation of the clinical case, medical history data were collected, in addition to radiography images, tomography and photographic material of the surgical procedure.Clinical case: This is a 63-year-old woman with a history of collagenopathy, who consulted for abdominal pain and distension. Although she had no signs of peritoneal irritation, diagnostic images revealed pneumoperitoneum and free fluid in the peritoneal cavity. Intestinal perforation was suspected, and an exploratory laparotomy was performed, in which intestinal and peritoneal cystic pneumatosis in was found.Conclusions: Not all cases of pneumoperitoneum require surgery. There are spontaneous cases without peritoneal irritation, secondary to intestinal cystic pneumatosis. In cases of pneumoperitoneum in stable patients, with a not very clear etiological diagnosis, and in those who wish to rule out intestinal perforation or ischemia by surgical exploration, diagnostic laparoscopy is a good option and less aggressive than laparotomy

ABSTRACT

The aim of this study was to determine whether a pneumoperitoneum of 10 mmHg combined or not with the Trendelenburg position could lead to significant changes in intraocular pressure (IOP), ocular pressure perfusion (OPP), and cardiorespiratory variables; as well as determine whether a correlation exists between IOP and mean arterial blood pressure (MAP), and/or partial pressure of carbon dioxide in arterial blood (PaCO2) in cats. Animals were allocated in two groups (n=7/group): GC (without inclination) and GTREN (Trendelenburg position). The variables were recorded before (baseline) and during 30 minutes (T5-T30) after insufflation. In GTREN, a reduction in heart rate was observed at T5 and in respiratory rate at T5 and T15. There was an increase in IOP at T5-T30 in comparison to baseline. There was a reduction in potential of hydrogen in arterial blood in both groups at all times in comparison to baseline. Partial pressure of carbon dioxide in arterial blood was increased at T15-T30 in GC and at T5-T30 in GTREN. In conclusion, the pneumoperitoneum of 10mmHg CO2 did not significantly affect IOP or OPP in cats anaesthetised with isofluorane and kept under spontaneous ventilation. However, induced pneumoperitoneum combined with Trendelenburg position resulted in an increase in IOP in cats subjected to the same anaesthetic conditions, but did not affect OPP.


O objetivo deste estudo foi determinar se o pneumoperitônio de 10 mmHg associado, ou não, à posição de Trendelenburg poderia levar a alterações significativas na Pressão Intraocular (PIO), Pressão de Perfusão Ocular (PPO) e variáveis cardiorrespiratórias, bem como determinar se havia correlação entre a PIO e a Pressão Arterial Média (PAM) e/ou Pressão Parcial de Dióxido de Carbono no Sangue Arterial (PaCO2) em gatos. Os animais foram alocados em dois grupos (n = 7/grupo): GC (sem inclinação) e GTREN (posição de Trendelenburg). As variáveis foram registradas antes (linha de base) e durante 30 minutos (T5-T30) após a insuflação. No GTREN, foi observada redução na frequência cardíaca em T5 e, na frequência respiratória, em T5 e T15. Houve aumento da PIO no T5-T30 comparativamente ao valor basal. Houve redução no Potencial de Hidrogênio no sangue arterial em ambos os grupos em todos os momentos comparativamente à linha de base. A Pressão Parcial de Dióxido de Carbono no sangue arterial aumentou em T15-T30 no GC e em T5-T30 no GTREN. Concluiu-se que o pneumoperitônio de 10mmHg CO2 não afetou significativamente a PIO ou a PPO em gatos anestesiados com isofluorano e mantidos sob ventilação espontânea. No entanto, o pneumoperitônio induzido combinado à posição de Trendelenburg resultou em aumento da PIO em gatos submetidos às mesmas condições anestésicas, mas não afetou a PPO.

ABSTRACT

Early removal of a percutaneous transhepatic biliary drainage (PTBD) tube commonly causes pneumoperitoneum. However, we encountered a patient who developed pneumoperitoneum even with an indwelling PTBD tube. An 84-year-old man was admitted with type III combined duodenal and biliary obstruction secondary to metastatic bladder cancer. A biliary stent was placed using a percutaneous approach, and a duodenal stent was placed endoscopically. A large amount of subphrenic free air was detected after the procedures. Laboratory tests indicated intestinal perforation; however, peritoneal signs were absent. The patient was treated conservatively using an indwelling Levin tube. Seven days later, the massive amount of subphrenic free air disappeared. Follow-up tubography revealed unrestricted bile flow into the small intestine, and the PTBD tube was removed. Prolonged endoscopic procedures in patients with a PTBD tract communicating with the gastrointestinal tract can precipitate pneumoperitoneum. Clinicians should be careful to avoid misdiagnosing this condition as intestinal perforation.

ABSTRACT

BACKGROUND: The current evidence on the safe use of supraglottic airway for pediatric laparoscopic surgeries is limited. Although i-gel has been successfully used in adult laparoscopic surgeries, to our knowledge, no studies have compared it to the endotracheal tube (ETT) in pediatric laparoscopic surgeries. This study evaluated the effectiveness of i-gel over ETT with regards to the respiratory and hemodynamic parameters during pediatric laparoscopic surgeries. METHODS: A total of 60 pediatric patients undergoing elective laparoscopic surgeries were randomly allocated to either the i-gel or ETT groups. Anesthetics used included ketamine, sevoflurane, and rocuronium. The primary outcome measured was the peak airway pressure (PAP) and the secondary outcomes measured were leak fraction, end-tidal CO₂, respiratory rate, insertion time, heart rate, blood pressure and perioperative complications. RESULTS: The PAP during surgeries was higher in the ETT group than in the i-gel group. There were no statistically significant differences in the leak fraction, end-tidal CO₂, and respiratory rate. The i-gel group had a shorter insertion time compared with the ETT group. The changes in heart rate were comparable in both groups. However, systolic and diastolic pressures were higher in the ETT group following intubation, before and after the creation of pneumoperitoneum. The incidence of perioperative complications was similar in both groups. CONCLUSIONS: The i-gel provided adequate ventilation with lower PAP compared with ETT. In addition, it provided minimal hemodynamic changes compared with ETT. Therefore, the i-gel may provide a suitable alternative to ETT in pediatric laparoscopic surgeries.

ABSTRACT

BACKGROUND: Laparoscopic donor nephrectomy is considered less painful than open nephrectomy but is still associated with significant postoperative pain. Studies reported that intraperitoneal instillation of local anesthetics provides uncertain pain relief after laparoscopic surgery. This randomized, double-blind study evaluated the effect of intraperitoneal nebulization of ropivacaine on postoperative pain relief after laparoscopic donor nephrectomy. METHODS: Sixty patients undergoing elective laparoscopic donor nephrectomy were randomly assigned to receive either an instillation of 20 ml 0.5% ropivacaine after the induction of pneumoperitoneum or nebulization of 5 ml 1% ropivacaine before and after surgery. The primary outcome was the degree of pain relief (static and dynamic) after surgery. The secondary outcomes were postoperative fentanyl consumption, incidence of shoulder pain, unassisted walking and postoperative nausea and vomiting (PONV). Data were collected in the postanesthesia care unit (PACU) and at 6, 24, and 48 h after surgery. RESULTS: Compared to patients in the instillation group, those in the nebulization group showed significant reductions in postoperative pain and fentanyl consumption, and none complained of significant shoulder pain (visual analog scale score ≥ 30 mm). Within 20 h of surgery, 13.3% of patients in the instillation group and 93.3% in the nebulization group started unassisted walking (absolute risk reduction, 38%; P = 0.001). In the nebulization group, PONV was significantly reduced in the PACU and at 6 h. CONCLUSIONS: Intraperitoneal nebulization of ropivacaine reduced postoperative pain, fentanyl consumption, referred shoulder pain, and PONV while enabling earlier mobility without any difference in the length of hospital stay.

ABSTRACT

PURPOSE: This study aimed to evaluate the clinical and radiologic findings suggestive of spontaneous intestinal perforation (SIP) in extremely-low-birth-weight infants (ELBWIs) with persistent gasless abdomen, and to investigate the usefulness of abdominal ultrasonography for the diagnosis of SIP. METHODS: In total, 22 infants with birth weights less than 1,000 g who showed persistent gasless abdomen on simple abdominal radiography were included. Perinatal, neonatal, and perioperative clinical findings were retrospectively reviewed, and the risk factors for intestinal perforation were evaluated. Abdominal sonographic findings suggestive of intestinal perforation were also identified, and postoperative short-term outcomes were evaluated. RESULTS: In total, eight of the 22 infants (36.4%) with gasless abdomen had SIP. The number of infants with patent ductus arteriosus who were treated with intravenous ibuprofen or indomethacin was significantly higher in the SIP group than in the non-SIP group (P<0.05). Greenish or red gastric residue, abdominal distension, or decreased bowel sound were more frequent in infants with SIP (P<0.05), in addition to gray or bluish discoloration of abdomen, suggestive of meconium peritonitis (P<0.05). Pneumoperitoneum on simple abdominal radiography was found in only one of the eight infants (12.5%) with SIP. Intramural echogenicity and echogenic extramural material on abdominal ultrasonography were exclusively observed in infants with SIP. Four infants (50%) with SIP died after surgical intervention. CONCLUSION: Intestinal perforation may occur in ELBWIs with gasless abdomen. As intramural echogenicity and extraluminal echogenic materials on abdominal ultrasonography are indicative of SIP, this technique could be useful for diagnosing SIP.

ABSTRACT

The goals of this study were, first, to evaluate the feasibility of inducing gastric perforation with 99% alcohol injection after electrocautery (EA-method), and, second, to observe “enhanced peritoneal stripe sign (EPSS)” and other lesions upon induction of gastric perforation. Six clinically normal beagle dogs were prepared for gastric perforation using endoscopy. After gastric perforation, EPSS and other lesions on ultrasonography were observed eventually (at 0 h, 3 h, day 1, day 2, day 3, day 4, day 5, and day 6). We graded the EPSS depending on its width and number. EPSS was observed until day 4 of the examination in all the 6 dogs. The grades of EPSS were the highest at 3 h and declined gradually. Peritoneal effusion was observed in all dogs at 3 h and on day 1. Regional bright mesenteric fat was confirmed in all dogs on days 3 and 4. In conclusion, gastric perforation can be induced by EA-method. EPSS and peritoneal effusion appear at a very early stage, and regional bright mesenteric fat was identified on days 3 and 4 in almost all dogs with gastric perforation.

ABSTRACT

BACKGROUND: The supraglottic airway device is an appropriate alternative to tracheal intubation in laparoscopic surgery. We compared the Baska MaskⓇ with i-gelⓇ by measuring the oropharyngeal leak pressure (OLP) and hemodynamic and respiratory parameters during laparoscopic cholecystectomy.METHODS: A total of 97 patients were randomly allocated to either i-gel group (n = 49) or Baska Mask group (n = 48). Insertion time, number of insertion attempts, fiber-optic view of the glottis, and OLP were recorded. Heart rate, mean arterial pressure, peak airway pressure (PAP), lung compliance, and perioperative complications were assessed before, during, and after pneumoperitoneum.RESULTS: There were no significant differences between the two groups regarding demographic data, insertion time, fiber-optic view of the glottis, and the use of airway manipulation. The OLP was higher in the Baska Mask group than in the i-gel group (29.6 ± 6.8 cmH₂O and 26.7 ± 4.5 cmH₂O, respectively; P = 0.014). Heart rate, mean arterial pressure, PAP, and lung compliance were not significantly different between the groups. The incidence of perioperative complications was small and not statistically significant.CONCLUSIONS: Both the i-gel and Baska Mask provided a satisfactory airway during laparoscopic cholecystectomy. Compared with the i-gel, the Baska Mask demonstrated a higher OLP.

ABSTRACT

A recent achalasia guideline suggests that peroral endoscopic myotomy (POEM) is a safe option for achalasia that is as effective as Heller myotomy. It is recommended that POEM should be performed under general anesthesia. The incidence of adverse events such as bleeding, perforation, and carbon dioxide insufflation-related complications was lower in POEM under endotracheal general anesthesia than in POEM under sedation. Subcutaneous emphysema, pneumothorax, pneumomediastinum, pneumoperitoneum, and accompanying hemodynamic instability can be caused by carbon dioxide insufflation. Treatment of possible physiological changes and adverse events during the POEM procedure from the point of view of anesthesiologists may give endoscopists a new perspective on improving patient safety. The territory of therapeutic endoscopy can be expanded through cooperation with other departments, including anesthesia services. Efforts to understand different perspectives will certainly help not only secure patient safety but also expand the area of treatment.

ABSTRACT

BACKGROUND: Elevated intracranial pressure (ICP), a disadvantage of laparoscopic or robotic surgery, is caused by the steep angle of the Trendelenburg position and the CO₂ pneumoperitoneum. Recently, sonographically measured optic nerve sheath diameter (ONSD) was suggested as a simple and non-invasive method for detecting increased ICP. This study aimed to explore the changes in ONSD in relation to different anesthetic agents used in gynecologic surgery.METHODS: Fifty patients were randomly allocated to two groups, sevoflurane (group SEV, n = 25) and propofol-based total intravenous anesthesia (TIVA) group (group TIVA, n = 25). The ONSD was measured at five time points (T0–T4): T0 was measured 5 min after induction of anesthesia in the supine position; T1, T2, and T3 were measured at 5, 15, and 30 min after CO₂ pneumoperitoneum induction in the Trendelenburg position; and T4 was measured at 5 min after discontinuation of CO₂ pneumoperitoneum in the supine position. Respiratory and hemodynamic variables were also recorded.RESULTS: The intra-group changes in mean ONSD in the Trendelenburg position were significantly increased in both groups. However, inter-group changes in mean ONSD were not significantly different at T0, T1, T2, T3, and T4. Heart rates in group TIVA were significantly lower than those in group SEV at points T1–T4.CONCLUSIONS: There was no significant difference in the ONSD between the two groups until 30 min into the gynecologic surgery with CO₂ pneumoperitoneum in the Trendelenburg position. This study suggests that there is no difference in the ONSD between the two anesthetic methods.

ABSTRACT

Resumen La cirugía para la corrección de las hernias ventrales gigantes, con pérdida de domicilio abdominal, representa un reto importante debido a la gran cantidad de comorbilidades potenciales. En esta patología se produce una migración de los órganos abdominales hacia el saco herniario; eventualmente, se atrofian los elementos de la pared y al tratar de retornarlos a su posición normal, se puede provocar múltiples efectos adversos en el paciente. Por eso, se debe realizar una cuidadosa planificación, preoperatoriamente. El uso de neumoperitoneo preoperatorio progresivo, permite una adaptación más adecuada desde el punto de vista fisiológico, tanto a nivel sistémico, como en la capacidad abdominal, para tolerar el retorno de los contenidos que han perdido su domicilio. Se presenta aquí el caso de una paciente femenina de 58 años, con una hernia ventral gigante con pérdida de domicilio abdominal, en cuyo manejo se utilizó la introducción preoperatoria progresiva de neumoperitoneo, descrita por primera vez por Goñi Moreno, en 1940.


Abstract Surgery for the correction of giant ventral hernias, with loss of abdominal domain, represents a major challenge due to the large number of potential comorbidities. In this pathology there is a migration of the abdominal organs to the hernia sac; eventually, the elements of the wall undergo atrophy and when trying to return the organs to their normal position, it can cause multiple adverse effects in the patient. Therefore, a careful planning must be carried out preoperatively. The use of progressive preoperative pneumoperitoneum, allows a more adequate adaptation from the physiological point of view, both at a systemic level, as in the abdominal capacity, to tolerate the return of contents that have lost their domain. We present here the case of a 58 year old female patient, with a giant ventral hernia with loss of abdominal domain, in whose management, the introduction of progressive preoperative pneumoperitoneum was used, described for the first time by Goñi Moreno, in 1940.

ABSTRACT

BACKGROUND/AIMS: Direct endoscopic pancreatic necrosectomy is increasingly being utilized to treat infected or symptomatic walled-off necrosis (WON) located close to the stomach or duodenum. Laterally-placed WON has traditionally been treated surgically. We evaluated a less utilized technique of sinus tract endoscopy (STE) for symptomatic laterally-placed WON. METHODS: Two hundred seventy-six patients with acute pancreatitis admitted in our hospital, 32 had symptomatic or infected WON requiring intervention. Of the 12 patients with laterally placed WON, 10 were treated by STE. STE was performed with a standard adult gastroscope passed through a percutaneous tract created by the placement of a 32-Fr drain. RESULTS: Ten patients (7 males; mean age, 43.8 years) underwent STE. Mean number of sessions was 2.3 (range, 1–4), with mean time of 70 minutes for each session (range, 15–70 minutes). While 9 patients had complete success, 1 patient had fever and chose to undergo surgery. Two patients developed pneumoperitoneum, which was treated conservatively. There was no mortality, cutaneous fistula, or recurrence during follow-up. CONCLUSIONS: Laterally placed WON can be successfully managed by STE performed through a percutaneously placed drain. Details of the technique and end-points of STE require further evaluation.

ABSTRACT

This paper presents a case report of tension pneumoperitoneum that occurred in a 4-month-old girl with intussusception during pneumatic reduction. Tension pneumoperitoneum is a rare but life threatening complication in air pressure enema that is commonly used to turn the intussuscepted bowel to its original position. The incidence of a simple pneumoperitoneum due to a bowel perforation associated with attempted pneumatic reduction for intussusception is as high as 4%. The simple pneumoperitoneum changed rapidly to tension pneumoperitoneum and immediate needle decompression was life-saving in this case. Similar to a tension pneumothorax, the diagnosis is clinical and management should not be delayed awaiting other confirmatory tests. The emergency physician must recognize this rare complication of pneumatic reduction and promptly treat the ensuing tension pneumoperitoneum after bowel perforation with immediate needle decompression as a part of the initial resuscitation.
