RESUMO
Introducción. La neumatosis quística intestinal se describe como la presencia de gas dentro de la pared intestinal. Es una entidad poco frecuente, con una incidencia del 0,03 % en la población global. Aparece con predilección en el género masculino después de los 45 años yse localiza principalmente en el intestino delgado (42 %) y el colon. Se puede asociar a varias condiciones que en ocasiones requieren manejo quirúrgico. Caso clínico. Se presenta el caso de un hombre 75 años, con antecedente de hipertensión arterial, quien consultó por un cuadro de 15 días de evolución consistente en distensión abdominal, dolor y estreñimiento. En urgencias se solicitó una radiografía de tórax que mostró neumoperitoneo y varios niveles hidroaéreos, por lo que el cirujano de turno consideró una posible ruptura de víscera hueca. Resultados. Fue llevado a laparotomía exploratoria, donde se identificó neumatosis quística intestinal y estómago muy aumentado de tamaño, compatible con gastroparesia. Como resultado del tratamiento brindado, el paciente tuvo un desenlace satisfactorio logrando alta médica, apoyado con cuidados básicos de enfermería. Conclusiones. Si bien los casos de neumatosis quística intestinal son de presentación inusual, se puede encontrar en pacientes con hallazgos imagenológicos de neumoperitoneo. Por eso, se debe realizar un análisis concienzudo de cada paciente e individualizar el caso para el correcto diagnóstico.
Introduction. Cystic pneumatosis intestinalis is described as the presence of gas within the intestinal wall. It is a rare entity, with an incidence of 0.03% in the global population. It appears with a predilection in the male gender after 45 years of age and is located mainly in the small intestine (42%) and the colon. It can be associated with several conditions that sometimes require surgical management. Clinical case. The case of a 75-year-old man with a history of high blood pressure is presented, who consulted for a 15-day history consisting of abdominal distention, pain and constipation. In the emergency room, a chest x-ray was requested, which showed pneumoperitoneum and several air-fluid levels. The surgeon on call considered a possible rupture of the hollow viscus. Results. The patient was taken to exploratory laparotomy, where intestinal cystic pneumatosis and a greatly enlarged stomach were identified, compatible with gastroparesis. As a result of the treatment provided, the patient had a satisfactory outcome, achieving medical discharge, supported with basic nursing care. Conclusions. Although cases of intestinal cystic pneumatosis have an unusual presentation, it can be found in patients with imaging findings of pneumoperitoneum. Therefore, a thorough analysis of each patient must be carried out and the case individualized for the correct diagnosis.

INTRODUCTION: Intestinal obstruction due to flanges is common in patients with a surgical history. OBJECTIVE: Describe a clinical case with adherenciolysis. Surgery could not be performed, so pneumoperitoneum was used as pre-conditioning for elective surgery. CLINICAL CASE: Patient with intestinal obstruction due to flanges, with impossibility of performing an adherenciolysis, for which catheters are installed to administer progressive pneumoperitoneum in order to optimize the release of flanges in elective surgery, undergoing the postoperative period with enterocutaneous fistula that required multidisciplinary management with percutaneous drainage, parenteral nutrition and nursing care, with a successful result. DISCUSSION: In a flange obstruction, an extensive adherenciolysis is often required, which carries a greater risk of intestinal injury and enterocutaneous fistula. In this case, we believe that it decreased due to the pneumoperitoneum used to generate more lax and manageable flanges. CONCLUSION: Postoperative flanges generate significant morbidity and its surgical management requires an adherenciolysis that may be laborious or impossible in the first instance, requiring in this case the use of progressive pneumoperitoneum for complete flange release, a technique not described in the literature for this purpose.
INTRODUCCIÓN: La obstrucción intestinal por bridas es frecuente en pacientes con antecedentes quirúrgicos. OBJETIVO: Describir un caso clínico con adherenciolisis frustra por cirugía, utilizando neumoperitoneo como preacondicionamiento para cirugía electiva. CASO CLÍNICO: Paciente con obstrucción intestinal por bridas, con imposibilidad de adherenciolisis, por lo que se instalan catéteres para administrar neumoperitoneo progresivo con el fin de optimizar la liberación de bridas en cirugía electiva, cursando en el postoperatorio con fístula enterocutánea que requirió manejo multidisciplinario con drenaje percutáneo, nutrición parenteral y cuidados por enfermería, que finalmente resultó exitoso. DISCUSIÓN: En una obstrucción por bridas muchas veces se requiere una adherenciolisis extensa que conlleva mayor riesgo de lesión intestinal y fístula enterocutánea, que en este caso creemos que disminuyó debido al neumoperitoneo utilizado para generar bridas más laxas y manejables. CONCLUSIÓN: Las bridas postoperatorias generan morbilidad importante y su manejo quirúrgico requiere adherenciolisis que puede resultar laboriosa o imposible en primera instancia, requiriendo en este caso el uso de neumoperitoneo progresivo para la liberación de bridas completa, técnica no descrita en la literatura para este fin.

Introducción. Las hernias gigantes con pérdida de domicilio son aquellas cuyo saco herniario alcanza el punto medio del muslo en bipedestación y su contenido excede el volumen de la cavidad abdominal. Estas hernias son un reto quirúrgico dada la difícil reducción de su contenido y del cierre primario de la fascia. Tienen mayor riesgo de complicaciones asociadas al síndrome compartimental abdominal, así como mayor tasa de recurrencia y morbilidad en los pacientes. Caso clínico. Paciente masculino de 81 años, reconsultante por hernia inguinoescrotal derecha gigante, de dos años de evolución, sintomática, con índice de Tanaka de 24 %. Se decidió aplicar el protocolo de neumoperitoneo secuencial (hasta 11.000 ml en total en cavidad) además de toxina botulínica en pared abdominal (dos sesiones). Resultados. Se logró la corrección exitosa de la hernia inguinoescrotal gigante, sin recaídas de su patología abdomino-inguinal. El paciente manifestó satisfacción con el tratamiento un año después del procedimiento. Conclusiones. El protocolo de neumoperitoneo secuencial es una alternativa en casos de hernias complejas, con alto riesgo de complicaciones, que requieren técnicas reconstructivas adicionales. La aplicación previa de toxina botulínica es un adyuvante considerable para aumentar la probabilidad de resultados favorables. Sin embargo, debe incentivarse la investigación en esta área para evaluar su efectividad.
Introduction. Giant hernias with loss of domain are those whose hernial sac reaches the midpoint of the thigh in standing position and whose content exceeds the volume of the abdominal cavity. These hernias are a surgical challenge given the difficult reduction of their contents and the primary fascial closure, with a higher risk of complications associated with abdominal compartment syndrome, as well as a higher rate of recurrence and morbidity in patients. Clinical case. A 81-year-old male patient with comorbidity, reconsulting due to a symptomatic giant right inguinoscrotal hernia of two years of evolution, with a Tanaka index of 24%, eligible for a sequential pneumoperitoneum protocol (up to a total of 11,000 cc in cavity) plus application of botulinum toxin (two sessions) in the abdominal wall. Results. Successful correction of the patient's giant inguinoscrotal hernia was achieved using this protocol, without recurrence of his abdomino-inguinal pathology and satisfaction with the procedure after one year. Conclusion. The sequential pneumoperitoneum protocol continues to be an important alternative in cases with a high risk of complications that require additional reconstructive techniques, while the previous application of botulinum toxin is a considerable adjuvant to further increase the rate of favorable results. However, research in the area should be encouraged to reaffirm its effectiveness.

Objective To explore the pneumoperitoneum signs of neonates on the bedside abdominal lying film.Methods The pneumoperitoneum signs of 52 neonates on the bedside abdominal lying films were analyzed retrospectively.Results Among 52 neonates with pneumoperitoneum,2 cases had no perforation,and there were 50 cases of digestive tract perforation,with 22 cases of gastric perforation,17 cases of small intestinal perforation and 11 cases of large intestinal perforation.Congenital muscular defect of gastric wall and necrotizing enterocolitis(NEC)were the most common causes of perforation.Forty-three cases with anteroposterior films all had pneumoperitoneum signs;and in 9 cases with anteroposterior and lateral films,6 cases with anteroposterior and lateral films all showed pneumoperitoneum signs,while 3 cases showed pneumoperitoneum signs only on lateral films.Pneumoperitoneum signs included 38 episodes of liver falciform ligament signs,37 episodes of football signs,22 episodes of Rigler signs,21 episodes of round liver ligament signs,10 episodes of liver area bright shadows,9 episodes of inverted"V"signs,6 episodes of scrotal gas,5 episodes of triangular signs,4 episodes of Cupola signs and 1 episodes of dolphin sign.Two or more signs were seen in 46 cases and three or more signs were seen in 31 cases.There was no statistically significant difference in the pneumoperitoneum signs except for scrotal gas among the three groups of gastric,small intestinal and large intestinal perforations(P>0.05).Conclusion Various signs such as liver falciform ligament signs,football signs,Rigler signs and round liver ligament signs can be seen on the bedside abdominal lying film for neonates pneumoperitoneum,and understanding the above signs is conducive to rapid and accurate diagnosis.
RESUMO
Abstract Background: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy. Methods: Eighty ASA I-II patients aged between 18 and 60 years scheduled for elective laparoscopic cholecystectomy were included. The study was registered in the Australian New Zealand Clinical Trials (ACTRN12618000771257). Patients were randomly divided into either Group C (control, PEEP not applied), or Group P (PEEP applied at 10 cmH20). Optic nerve sheath diameter, hemodynamic, and respiratory parameters were recorded at six different time points. Ocular ultrasonography was used to measure optic nerve sheath diameter. Results: Peak pressure (PPeak) values were significantly higher in Group P after application of PEEP (p = 0.012). Mean respiratory rate was higher in Group C at all time points after application of pneumoperitoneum (p < 0.05). The mean values of optic nerve sheath diameters measured at all time points were similar between the groups (p > 0.05). The pulmonary dynamic compliance value was significantly higher in group P as long as PEEP was applied (p = 0.001). Conclusions: During laparoscopic cholecystectomy, application of 10 cmH2O PEEP did not induce a significant change in optic nerve sheath diameter (indirect indicator of intracranial pressure) compared to no PEEP application. It would appear that PEEP can be used safely to correct

Introducción. La neumatosis intestinal se define como la presencia de quistes aéreos en la pared del tracto digestivo, a nivel submucoso o subseroso, que comprometen principalmente el intestino delgado. Las manifestaciones clínicas son inespecíficas y los hallazgos imagenológicos son fundamentales en el enfoque diagnóstico. El manejo puede ser médico o quirúrgico, dependiendo del compromiso intestinal y las complicaciones asociadas. Caso clínico. Hombre de 78 años, que ingresó por cuadro de dolor abdominal crónico, con hallazgos imagenológicos de neumoperitoneo. Al ser llevado a intervención quirúrgica se encontró neumatosis intestinal masiva del íleon, requiriendo resección intestinal. Resultado. El paciente presentó una evolución postoperatoria satisfactoria y fue dado de alta, sin complicaciones. Conclusión. La neumatosis intestinal es una enfermedad poco frecuente, que se presenta principalmente en hombres. La sospecha diagnóstica se confirma con imágenes tomográficas. Los pacientes candidatos para el manejo médico deben presentar causas con curso benigno, sin compromiso hemodinámico ni complicaciones. El manejo quirúrgico se reserva para pacientes con abdomen agudo o signos de sepsis.
Introduction. Intestinal pneumatosis is defined as the presence of air cysts in the wall of the digestive tract at the submucosal or subserosal level, mainly compromising the small intestine. The clinical manifestations of the disease are nonspecific, and the imaging findings are essential in the diagnostic approach. Management can be conservative and/or surgical depending on the intestinal compromise and associated complications. Clinical case. The following is the case of a 78-year-old man, who was admitted due to chronic abdominal pain with imaging findings of pneumoperitoneum. Patient underwent surgery and a massive ileum pneumatosis was found, requiring intestinal resection. Results. The patient Ìs postoperative course was uneventful, and he was discharged without further complications. Conclusions. Intestinal pneumatosis is an uncommon disease, which mostly affect men population. Clinical suspicion of this condition should be confirmed with abdominal tomography. Candidates for medical management are those with benign course pathologies without hemodynamic compromise and/or complications. Surgical management should be reserved for patients with acute abdomen or sepsis.

Introduction: Pneumatosis cystoides intestinalis (PCI) is a rare entity characterized by cysts or air bubbles in the intestinal wall, usually asymptomatic. Its uncomplicated forms are managed conservatively, and the severe ones require surgical intervention. The presence of pneumoperitoneum is a disturbing radiological finding but not an indicator of surgical intervention. Clinical case: A 23-year-old man presented with weight loss, diarrhea, and rectal bleeding; a colonoscopy showed multiple violaceous cysts in the sigmoid and descending colon that collapsed after puncture and biopsies. Computed tomography (CT) confirmed the diagnosis and the presence of an encapsulated pneumoperitoneum. The absence of signs of potential lethality allowed conservative treatment with clinical remission during the first eight months of follow-up. Discussion: The pathophysiology of PCI is not well defined. Our patient's diagnosis was incidental when performing a colonoscopy for rectal bleeding. Asymptomatic encapsulated pneumoperitoneum should be interpreted as an important but not decisive sign of surgical intervention. Its presence, along with the medical history and physical, biochemical, endoscopic, and imaging examination, can prevent unnecessary surgery.
Introducción: la neumatosis quística intestinal es una entidad infrecuente, caracterizada por la presencia de quistes o burbujas de aire en la pared intestinal, usualmente asintomática. Sus formas no complicadas son manejadas conservadoramente y las graves requieren intervención quirúrgica. La presencia de neumoperitoneo es un hallazgo radiológico inquietante, pero no es indicador de intervención quirúrgica. Caso clínico: hombre de 23 años con pérdida de peso, diarrea y rectorragia, la colonoscopia mostró múltiples quistes violáceos localizados en el sigmoide y descendente que colapsaron tras la punción y biopsias, la tomografía axial computarizada (TAC) confirmó el diagnóstico y la presencia de un neumoperitoneo encapsulado. La ausencia de signos de potencial letalidad permitió un tratamiento conservador con remisión clínica durante los primeros 8 meses de seguimiento. Discusión: la fisiopatología de la neumatosis quística intestinal no está bien definida. En el paciente presentado el diagnóstico se realizó de forma incidental al realizar una colonoscopia por una rectorragia. El neumoperitoneo asintomático encapsulado debe interpretarse como un signo importante pero no determinante de intervención quirúrgica y su presencia junto con los antecedentes médicos, examen físico, bioquímico, endoscópico e imagenológico puede evitar cirugías innecesarias.
RESUMO
A 26 year old male patient presented with abdominal distension following ingestion of liquid nitrogen and was diagnosed to have massive pneumoperitoneum both clinically and radiologically. Patient underwent emergency laparotomy in search of perforation, the stomach, Intestines was examined and no hollow viscous perforation was found. All abdominal contents were normal, no tissue necrosis or haemorrhage, no free ?uid or bleeding was found in the abdomen. Two abdominal drains were placed in the lesser sac and the pelvis and abdomen were closed. The patient was stable post operatively and tolerated oral feeds and discharged on 7th post operative day. Our study revealed that despite of having massive pneumoperitoneum, site of perforation cannot be identi?ed
RESUMO
La hernia incisional compleja es un desafío para el cirujano. Son ampliamente conocidos los factores que han permitido mejorar los resultados de la reparación herniaria, entre ellos el neumoperitoneo preoperatorio. Durante la insuflación preoperatoria, el aire difunde tanto en la cavidad abdominal como en el saco herniario. Sin embargo, gran porcentaje del contenido administrado, se distribuye mayormente en el saco herniario y no en la cavidad abdominal. En Latinoamérica, diversos equipos de cirujanos de pared abdominal han compartido experiencias en lo que respecta a la optimización de esta técnica como adyuvancia para el manejo de las hernias complejas. En este contexto, y para optimizar la distribución del aire insuflado hacia la cavidad abdominal, se comenzó a utilizar un dispositivo externo de compresión. Este trabajo busca estandarizar por primera vez esta técnica durante el neumoperitoneo preoperatorio buscando disminuir el volumen de aire insuflado, los días de neumoperitoneo y, por lo tanto, los días de hospitalización previo a la cirugía.
Complicated incisional hernia is challenging for surgeons. The factors that have improved the results of hernia repair are widely known, including preoperative pneumoperitoneum. During preoperative insufflation, air diffuses into both the abdominal cavity and the hernia sac. However, a large percentage of the administered content is distributed mainly in the hernia sac and not in the abdominal cavity. Latin-American teams of abdominal wall surgeons have shared experiences regarding the optimization of this technique as an adjuvant for the management of complicated hernias. In this context and to optimize the distribution of the insufflated air into the abdominal cavity, an external compression device began to be used. This article aims to standardize this technique for the first time during preoperative pneumoperitoneum. The target is to reduce the volume of air insufflated, the days of pneumoperitoneum and, therefore, the days of hospitalization prior to surgery.
RESUMO
Pneumobilia is a phenomenon associated with the presence of a biliary-enteric fistula or manipulation of the bile duct during procedures or surgical interventions that cause dysfunction of the sphincter of Oddi. A known, but infrequently reported event, is the increase in intraabdominal pressure after closed abdominal trauma, which causes pneumobilia due to a mechanism of retrograde air leakage towards the bile duct. Depending on the general compromise of each patient, the prognosis can vary from a benign condition that only requires conservative management, to being life threatening. We present the case of a 75-year-old male patient who, after suffering a closed thoraco-abdominal trauma, presented with rib fracture and, in addition, gallbladder wall rupture, pneumoperitoneum, pneumobilia, and pneumowirsung, having a favorable clinical course after receiving conservative management.
La neumobilia es un fenómeno asociado a presencia de fístula bilioentérica o manipulación de la vía biliar durante procedimientos o intervenciones quirúrgicas que condicionan disfunción del esfínter de Oddi. Un evento poco reportado, pero ya conocido, es el aumento de la presión intraabdominal tras un trauma abdominal cerrado, que condiciona neumobilia por un mecanismo retrógrado de fuga de aire hacia la vía biliar. Según el compromiso general de cada paciente, el pronóstico puede variar desde un cuadro benigno, que solo requiere un manejo conservador, hasta ser amenazante para la vida. Se presenta el caso de un paciente varón de 75 años, quien después de presentar un trauma toracoabdominal cerrado cursa con fractura costal y, además, ruptura de pared vesicular, neumoperitoneo, neumobilia, y neumowirsung, cursando con evolución favorable tras recibir manejo conservador.
RESUMO
Abstract Concomitant use of a nasopharyngeal catheter is frequently used for oxygen supply during fiberoptic bronchoscopy (FOB). This is a procedure that presents possible complications that are not negligible. We demonstrate the case of a 61-year-old woman who underwent FOB due to a history of hemoptoic sputum. During the procedure, gastric rupture occurred with a large pneumoperitoneum and bilateral pneumothorax requiring immediate drainage of the air and an emergent laparotomy. This was probably a complication of the nasopharyngeal catheter. The knowledge of these complications is essential for their correct identification and treatment.

Objective To evaluate the effects of low pneumoperitoneum pressure under deep muscle relaxation on inflammatory factors,oxidative stress and morphology of distal greater omental capillary endothelial cells in patients undergoing laparoscopic radical gastrectomy(LAG)for gastric cancer.Methods Sixty patients with LAG were selected from January to June 2022,45 males and 15 females,aged 40-75 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ.Patients were randomly divided into two groups:low pneumoperitoneum pressure group(group PL)and the control group(group PH),30 patients in each group.Both groups were treated with deep muscle relaxation condition(PTC=1 or 2),and the pneumo-peritoneum pressure was set at 10 mmHg in group PL,and 14 mmHg in group PH.The duration of pneumo-peritoneum maintenance,surgical time,anesthesia time,extubation time,PACU stay time,postoperative hospitalization time,the number of effective PCIA compressions and total PCIA compressions within 48 hours after surgery,and number of relief analgesia were recorded.The plasma concentrations of interleukin-1 β(IL-1β),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α),contents of malondialdehyde(MDA),superoxide dismutase(SOD),and reduced glutathione(GSH)were recorded 5 minutes before induction,5 minutes before abdominal closure,and 24 hours after surgery.The morphology of capillary en-dothelial cells in the omental membrane was observed 5 minutes after opening abdomen and 5 minutes before abdominal closure.Results Compared with group PH,the number of effective PCIA compressions and total PCIA compressions in group PL were significantly reduced within 48 hours after surgery(P<0.05),the concentration of IL-6 was significantly decreased in group PL 5 minutes before abdominal closure and 24 hours after surgery(P<0.05),the content of MDA was significantly decreased in group PL 5 minutes be-fore abdominal closure(P<0.05).The endothelial cell of the greater omental capillaries was slightly edematous and unevenly thick,while the nuclear contractile function was slightly weakened and the vascular lumen was moderately narrowed in group PL 5 minutes before abdominal closure.By contrast,the group PH showed obvious swelling of the endothelial cells with significant intracellular fluid accumulation and severe edema,while the vascular lumen turned to be extremely narrow and the nucleus became severe swelling.Conclusion The use of deep muscle relaxation with low abdominal pressure at 10 mmHg in laparoscopic surgery for gastric cancer can diminish inflammation and oxidative stress,alleviating postoperative pain,re-duce the pneumoperitoneum pressure-induced damage on capillary endothelial cells,and leading to better early postoperative recovery.
RESUMO
Objective To investigate the characteristics of liver deformation and changes in abdominal vascular diameter under artificial pneumoperitoneum based on CT images,and also to reveal the impact of intestinal adhesion on these characteristics.Methods A retrospective study was conducted on 61 patients who underwent abdominal CT scan and artificial pneumoperitoneum CT.Eight cases did not meet the inclusion criteria.The sample included 41 patients with postoperative intestinal adhesion(POIA)and 12 patients without POIA.A three-dimensional post-processing software was used to quantify the gas volume,liver volume,liver surface area,and lumen of the abdominal aorta,inferior vena cava,and portal vein on CT images of patients who underwent abdominal CT scan and artificial pneumoperitoneum CT.The measured indices were compared before and after artificial pneumoperitoneum in all patients,and the impact of intestinal adhesion on the aforementioned indices was evaluated.Results At equivalent levels of pneumoperitoneum pressure,no statistically significant difference was observed in the quantity of gas in the abdominal cavity between patients with and without POIA(P=0.753).In the absence of pneumoperitoneum,POIA patients exhibited a significantly higher liver volume than non-adhesion patients(P<0.01).Following the application of artificial pneumoperitoneum pressure,both liver volume and liver surface area were reduced in all patients,with a more pronounced decrease in POIA group(P=0.003,P=0.002).In addition,the reductions in the internal diameters of the inferior vena cava at three locations and the portal vein position 1 were also observed in all patients(P<0.05).Notably,the POIA group exhibited more significant decrease in the internal diameters of inferior vena cava position 1 and the portal vein position 1(P=0.022,P=0.038).No significant differences were observed in the changes of internal diameter of other blood vessels or in the intergroup comparison.Conclusion Artificial pneumoperitoneum can reduce the volum,the surface area of liver,and the inner diameter of some abdominal vessels,which provides a scientific basis for navigation and real-time correction in laparoscopic abdominal surgery for patients,especially for patients with POIA.
RESUMO
Objective:To study the effects of different carbon dioxide (CO 2) pneumoperitoneum pressures combined general anesthesia with sevoflurane-propofol on cerebral oxygenmetabolism balance and stress response in elderly patients undergoing colorectal cancer surgery. Methods:A retrospective collection of 100 colon cancer cases from February 2020 to February 2021 in the Jiading Branch of Shanghai First People′s Hospital (Jiangqiao Hospital, Jiading District) and the Shanghai First People′s Hospital were divided into low pressure group and high pressure group according to different CO 2 pneumoperitoneum pressure values, each with 50 cases and 12 mmHg(1 mmHg = 0.133 kPa) and 18 mmHg CO 2 pneumoperitoneum pressure values were used to inflate, and the perioperative status, cerebral oxygen metabolism status, and stress response of the two groups were observed. Results:The take food time, first time out of bed in the low pressure group were lower than those in the high pressure group: (45.67 ± 7.34) h vs. (49.67 ± 8.16) h, (34.69 ± 8.26) h vs. (39.87 ± 7.16) h, there were statistical differences( P<0.05). The time of first anal exhaust and hospital stay in the two groups had no significant differences ( P>0.05). Repeated measures analysis of variance results showed that the levels of partial pressure of carbon dioxide in artery, oxyhemoglobin saturation, arterial blood lactate acid, benous blood lactic acid were different followed the time and treatment methods ( P<0.05). The levels of heart rate, mean arterial pressure, cortisol and thyroid stimulating hormone in the low pressure group were higher than those in the high pressure group: (73.68 ± 6.35) beats/min vs. (84.84 ± 6.86) beats/min, (81.67 ± 13.68) mmHg vs. (93.68 ± 14.37) mmHg, (100.24 ± 12.34) μg/L vs. (135.68 ± 13.69) μg/L, (3.12 ± 0.43) mU/L vs. (3.54 ± 0.34) mU/L, there were statistical differences ( P<0.05). Conclusions:Different CO 2 pneumoperitoneal pressures affect the brain oxygen metabolism of patients, and clinical attention should be paid to them.
RESUMO
Resumen Introducción: El procedimiento de neumoperitoneo progresivo preoperatorio para el manejo de hernias gigantes con "Pérdida de dominio" o Pérdida de derecho a domicilio" fue introducido en 1940 por Goñi Moreno en Argentina. Autores como Herszage, Berlemont, Koontz, Gravez y Martínez Munive presentaron variaciones interesantes del método original. Su uso se recomienda para preparación previa de pacientes con hernias gigantes y grandes contenidos de vísceras en el saco herniario, en los cuales no sería posible su re-introducción y efectuar la hernioplástia, o en los que su reducción de manera forzada pudiera llevar al paciente al desarrollo de un síndrome compartimental abdominal en el postoperatorio inmediato. Caso clínico: Paciente de sexo masculino de 65 años de edad, que presenta cuadro clínico de un mes de evolución caracterizado por dolor a nivel de la región inguinal izquierda, en el cual se evidencia presencia de hernia inguino escrotal gigante izquierda, no reductible, con aproximadamente un 40% de contenido abdominal. Resultados: La mayoría de los estudios describen el uso del neumoperitoneo progresivo para la reparación de las eventraciones gigantes, sin embargo, en nuestra experiencia y en la de otros autores, esta técnica también puede utilizarse para resolver las hernias inguinales y umbilicales gigantes, con buenos resultados. En todos los casos se aconseja utilizar material protésico. Conclusión: El uso del neumoperitoneo preoperatorio progresivo, se trata de una técnica segura y fácil de realizar que puede complementar las técnicas de eventroplastía complejas, aportando ventajas en la preparación de los pacientes con grandes defectos de pared abdominal y obteniendo buenos resultados.
Abstract Introduction: The procedure of progressive preoperative pneumoperitoneum for the management of giant hernias with "Loss of domain" or "Loss of the right of domain" was introduced in 1940 by Goñi Moreno in Argentina, followed in later years by authors such as Herszage, Berlemont, Koontz, Gravez and Martínez Munive, all with some interesting variations of the original method. Its use is recommended for previous preparation of patients with giant hernias and large contents of viscera in the hernial sac, in which it would not be possible to re-introduce and perform hernioplasty, or in which its forced reduction could lead to the patient to the development of an abdominal compartment syndrome in the immediate postoperative period. Clinical case: A 65-year-old male patient with a clinical picture of one month of evolution characterized by pain in the left inguinal region. There was evidence of a giant left inguinal scrotum, not reducible, with approximately 40% abdominal contents. Results: Most studies describe the use of progressive pneumoperitoneum for the repair of giant hernias, however, in our experience and in that of other authors, this technique can also be used to resolve hernias giant inguinal and umbilical, with good results. In all cases it is recommended use prosthetic material. Conclusion: The use of progressive preoperative pneumoperitoneum is a safe and easy-to-perform technique that can complement complex eventroplasty's techniques, providing advantages in the preparation of patients with large abdominal wall defects and obtaining good results.

Objective: To observe the hemodynamic effects of a single bolus dose of dexmedetomidine in patients undergoing elective laparoscopic surgeries.Methods: A total of 60 adult patients were randomized into two groups of 30 each. Group D patients were given 1 µg/kg dexmedetomidine in 50 mL of saline as a single-dose infusion over 10 min before induction. Group S patients were given a 50-mL 0.9% NS slow infusion over 10 min. Groups D and S patients were premedicated 10 min prior to surgery. Baseline vital and hemodynamic parameters were monitored during the perioperative period. Conclusion: Premedicating with a single bolus of 1 µg/kg IV dexmedetomidine has been proven safe and effective in maintaining perioperative hemodynamic stability, although few developed bradycardia and hypotension, which were managed without any adverse outcome. Furthermore, dexmedetomidine effectively reduced the incidence of shivering.

Resumen: Objetivo: Evaluar el comportamiento de las presiones intrapulmonares con la inversión del índice inspiración espiración durante la colecistectomía electiva videolaparoscópica. Material y métodos: Se realizó un ensayo clínico controlado fase tres acerca de tales presiones intrapulmonares, durante operaciones de colecistectomía laparoscópica, en el Hospital Universitario «Manuel Ascunce Domenech¼, en el período de septiembre del 2016 a febrero del 2020. El universo estuvo constituido por los pacientes que cumplieron con los criterios de inclusión, y una muestra de 106 de ellos, los cuales se dividieron en dos conjuntos de 53 personas cada uno, por método aleatorio simple. La fuente primaria de obtención de datos la constituyeron las historias clínicas y el resultado de una encuesta. Los datos se recogieron en un modelo diseñado en correspondencia con la bibliografía. Resultados: Se presentó aumentos de la presión inspiratoria pico y presión meseta luego del neumoperitoneo, con descenso de ambas tras la transposición del índice I:E, además de hipertensión arterial, arritmias e hipotensión arterial, sin guardar relación con la aplicación del indicador I:E invertido. Conclusiones: La inversión de la inspiración espiración contribuyó a mejorar los efectos del neumoperitoneo sobre dichas presiones intrapulmonares, manteniendo una oxigenación adecuada y nulos efectos cardiovasculares.
Abstract: Objective: Evaluating the behavior of intrapulmonary pressures with the inversion of the inspiration expiration index, during elective videolaparoscopic cholecystectomy. Material and methods: A phase three controlled clinical trial was conducted on intrapulmonary pressures during laparoscopic cholecystectomies at the «Manuel Ascunce Domenech¼ University Hospital, from September 2016 to February 2020, the universe consisted of patients who met the inclusion criteria, from which a sample of 106 patients was selected, by a simple randomizing method. The primary source of data collection was the medical records and the result of a survey. These data were collected in a model designed in correspondence with the bibliography reviewed. Results: Measured by variation in peak inspiratory pressure and plateau pressure after pneumoperitoneum, with significant decrease of both after inversion of I:E index. More than half of the patients presented arterial hypertension, arrhythmias and arterial hypotension, without them being related to the application of the inverted I:E index. Conclusions: The inversion of inspiratory expiration contributed to improve the effects of pneumoperitoneum on intrapulmonary pressures, with adequate oxygenation and no cardiovascular effects.
RESUMO
Introduction: Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by gas-filled cysts in the intestinal wall. Although rare, it may also involve other regions, such as the mesentery. PCI is classified as primary or secondary and is associated with multiple predisposing factors. It may be associated with either a benign condition or a potentially fatal condition, such as mesenteric ischemia. The objective of this study was to review the medical literature on the rare benign presentations of PCI, excluding cases associated with intestinal ischemia.Methods: We conducted a systematic literature review according to the PRISMA statement. We searched PubMed and LILACS databases for articles published between January 2015 and December 2020 using the following Medical Subject Headings: "pneumatosis cystoides intestinalis" and "pneumoperitoneum," "pneumatosis intestinalis," and "pneumoperitoneum" or "mesenteric pneumatosis."Results: We included 51 articles comprising 58 patients with PCI and pneumoperitoneum. Most patients were men, and mean patient age was 64.9 years. We identified an idiopathic etiology in 29.31% of cases, and the most common predisposing factor was immune dysfunction (29.31%). A total of 24.13% of patients were asymptomatic. The most commons symptoms were abdominal pain (43.10%), nausea and vomiting (41.37%), and abdominal distention (37.93%). Diagnostic surgery was conducted in 26 patients (44.82%). Only 1 patient underwent surgical treatment.Conclusions: PCI is a clinical condition that may have a benign etiology and not require surgery. Treatment of the benign etiology is conservative. Thus, life-threatening conditions should be excluded in all cases.
