A case report of bilateral chylous hemothorax presenting after laparoscopic renal pedicle lymphatic disconnection / 中华泌尿外科杂志

Laparoscopic renal pedicle lymphatic disconnection is the most effective method for treating chyluria that has failed to respond to conservative management. Chylous hemothorax is a rare clinical occurrence resulting from the anatomic abnormality. This paper reported a case, who was admitted with painless gross hematuria for 1 month and was diagnosed with left chylous hematuria. Laparoscopic left renal pedicle lymphatic disconnection was performed, and bilateral chylous hemothorax occurred after the operation. After conservative treatment such as bilateral closed thoracic drainage and blood transfusion support, the patient recovered well. After 2 months of follow-up, there was no obvious effusion in the bilateral thoracic cavity, and the chylous test of urine fluid was negative.

Objective:To evaluate whether vagus nerve-guided robotic splenectomy and azygoportal disconnection (VNRSD) is feasible and safe and to determine whether VNRSD can be competent for well protecting vagus nerve.Methods:In this prospective clinical study, 12 cirrhotic patients with portal hypertension, hypersplenism and esophagogastric variceal bleeding (EVB) who accepted VNRSD at the Clinical School of Medicine of Yangzhou University between January 2022 and March 2022 were included, including 5 females and 7 males, aged (56.6±11.6) years old. Clinical data such as visual analog scale (VAS) pain score, conversion to laparotomy, esophagogastric variceal bleeding, and death were collected. The patients were asked to reexamine in the outpatient department 1 month after the operation, and the diarrhea, delayed gastric emptying and epigastric fullness were followed up.Results:VNRSD was successfully performed in all patients. There was no conversion to open or laparoscopic operations. The operation time was (170.0±16.8) min, blood loss was (60.8±11.3) ml, VAS pain score on the first day was (2.2±0.9) scores, and the postoperative hospital stay was (7.7±0.7) d, the four patients had main portal vein system thrombosis on the 7th day after operation. At the first day after operation, all patients were mange to take semi-fluid and off-bed activity. There were no incisional complications, pneumonia, gastric fistula, pancreatic fistula, and abdominal infection. No patients suffered from diarrhea, delayed gastric emptying, and epigastric fullness. None of the patients suffered from esophagogastric variceal bleeding, hepatic encephalopathy or death after operation and one month after operation, and the esophagogastric variceal were significantly improved. And no patient complained of abdominal distension or diarrhea.Conclusion:VNRSD procedure is not only technically feasible and safe, but also effectively protects anterior and posterior vagal trunks and all their branches, completely eradicating digestive system complications.

Objective:To investigate the value of liver fibrosis serum markers in predicting esophagogastric variceal re-bleeding (EGVR) after laparoscopic splenectomy and azygoportal discon-nection (LSD).Methods:The prospective study was conducted. The clinical data of 155 cirrhotic portal hypertension patients with EGVR after LSD in the Clinical Medical College of Yangzhou University from September 2014 to January 2017 were selected. Observation indicators: (1) grouping situations of the enrolled patients; (2) risk factors analysis for postoperative EGVR; (3) prediction of postoperative EGVR; (4) follow-up. Follow-up was conducted using telephone interview, outpatient examination and hospitalization. Patients were followed up once every 3 months after operation to detect occurrence of EGVR and survival of patient up to January 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data wite skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. The area under curve (AUC) of receiver operating characteristic (ROC) curve was used to estimate the diagnostic efficiency. The Youden index was used to determine the optimal cut-off point. Results:(1) Grouping situations of the enrolled patients. A total of 155 patients were selected for eligibility. There were 106 males and 49 females, aged (53±11)years. Of the 155 patients, there were 21 cases with EGVR in the postoperative 1 year and 134 cases without EGVR in the postoperative 1 year. The protein expression of laminin and collagen Ⅳ were 100.3(range, 16.1?712.2)μg/L and 68.4(range, 35.0?198.8)μg/L in patients with EGVR, vs 35.5(range, 2.0?521.2)μg/L and 43.5(range, 4.3?150.4)μg/L in patients without EGVR, showing significant differences between them ( Z=?4.55, ?4.52, P<0.05). (2) Risk factors analysis for postoperative EGVR. According to the Youden index, the optimal cut-off point of protein expression of laminin and collagen Ⅳ were 64.0 μg/L and 65.0 μg/L, respec-tively. Results of multivariate analysis showed that the protein expression of laminin ≥64.0 μg/L and the protein expression of collagen Ⅳ ≥65.0 μg/L were independent risk factors for postoperative EGVR ( odds ratio=9.69, 8.16, 95 confidence intervals as 3.05?30.82, 2.65?25.15, P<0.05). (3) Prediction of postoperative EGVR. Results of ROC curve showed that the AUC of laminin and collagen Ⅳ in predicting postoperative EGVR was 0.79 (95% confidence interval as 0.66?0.92), with sensi-tivity as 0.62 and specificity as 0.96. (4) Follow-up. All the 155 patients were followed up for 12(range, 1?12)months. During the follow-up, there were 21 of the 155 patients (13.55%) with post-operative EGVR, including 3 cases died of EGVR. Of the 21 patients with postoperative EGVR, there were 6 cases with postoperative EGVR during the first month after operation including 2 cases died, 5 cases with postoperative EGVR at postoperative 1?3 month, 6 cases with postoperative EGVR more than 3 month and less than 6 month after operation and 4 cases with postoperative EGVR at postoperative 6?12 months including 1 case died at postoperative 12 month. Conclusions:Laminin and collagen Ⅳ show satisfactory ability to predict EGVR after LSD.

White matter hyperintensities: repercussion on grey matter structures of the brain / Hiperintensidades da substância branca: repercussão em estruturas da substância cinzenta do cérebro

The extensive white matter of the brain, which comprises about one half of its volume, is constituted by an intricate and interwoven assemble of nerve fibers. The WMH (leukoaraiosis) represent the most frequent ischemic type of lesion of SVD, affecting the white matter. These lesions may be apparent or normal appearing on neuroimaging. In both cases such lesions may interrupt the affected white matter fibers, with consequent disconnection syndromes, and atrophy of the denervated grey matter structures. These conditions affect the structural neural networks (connectome), with functional repercussion on the cognitive and behavioral domains.

A extensa substância branca do cérebro, que compreende cerca da metade do seu volume, é constituída por um intricado e entrelaçado conjunto de fibras nervosas. As HSB (hiperintensidades da substância branca) (leucoaraiose) representam o mais frequente tipo de lesão isquêmica da DPV (doença dos pequenos vasos) que afeta a substância branca. Essas lesões podem ser aparentes ou de aparência normal na neuroimagem. Em ambos os casos tais lesões podem interromper essas fibras da substância branca, com consequente síndromes por desconexão e atrofia de estruturas de substância cinzenta desnervadas. Essas condições afetam as redes neurais estruturais (conectoma), com repercussão funcional nos domínios cognitivo e do comportamento.

There was no patient undergoing gastrointestinal hemorrhage and gastric reten-tion.Conclusion:Da Vinci robotic assisted vagus nerve-preserving splenectomy and azygoportal disconnection is safe and feasible for the treatment of cirrhotic portal hypertension patients with esophagogastric variceal bleeding and hypersplenism.

Decerebration induced by surgical transection of cerebral ganglion of crayfish

Background: Since the neural structures of the crayfish brain closely resemble their equivalent in the mammals. This can be suggested by observing the similarity that exists in the brain divided by the surgical transection of the crayfish brain in which the protocerebrum remains attached to the first two cranial nerves, findings also described by Frederic Bremer in 1935 in cats with cerebral transection.Methods: Total 11 Adult male crayfish were trained to respond with defense reflex, the animals were placed in water at 0°C, remained without any movement, and subsequently through a small incision of 3 mm in diameter in the medial antero region and dorsal cephalothorax region, a surgical section of the cerebral ganglion was performed. Immediately after surgery, metal microelectrodes were implanted to collect the activity of the photoreceptors and visual fibers.Results: Once the defense reflex begins to recover in previously decerebrated crayfish, it means that it shows signs of reconnection. The isolated protocerebrum with the deutocerebrum olfactory lobe remain alive for several days and the neuronal connections were reestablished, as measured throughout the bilateral defense activity. The defense reflex was observed in all animals and then recovered after surgery.Conclusions: The crayfish is an excellent model to work the visual activity, all coding of visual information was suppressed in de-cerebrated crayfish. The recovery of the neural disconnection is observed from 40 days, where the defence reflex appears again before visual stimuli.

Motivaciones prosociales y desconexión moral en adolescentes desvinculados de grupos armados ilegales / Prosocial motivations and moral disengagement in adolescents disengaged from illegal armed groups

Resumen El artículo se propone describir las principales motivaciones prosociales y los mecanismos cognitivos de desconexión moral, así como analizar la relación entre ambos constructos en adolescentes desvinculados de grupos armados ilegales, ubicados en la modalidad Hogar Sustituto Tutor del Instituto Colombiano de Bienestar Familiar (ICBF), en Manizales, Colombia. Es una investigación cuantitativa, diseño no experimental de tipo transversal; estudio de alcance descriptivo-correlacional. Se realizó con una muestra no probabilística, compuesta de 35 adolescentes. Se utilizaron los instrumentos Escala de Tendencias Prosociales-revisada (PTM-R) y el Cuestionario de Mecanismos de Desconexión Moral (MMDS). Se obtuvo como resultados que las tendencias prosociales con mayor valor medio fueron complacencia y emergencia; los mecanismos de desconexión moral más utilizados fueron atribución de culpa, justificación moral y distorsión de las consecuencias. No se encontraron diferencias significativas entre hombres y mujeres. Se encontraron correlaciones significativas, de signo negativo, entre las tendencias prosociales por complacencia y altruista con la desconexión moral. El desplazamiento de la responsabilidad disminuye en un 34 % la probabilidad de que los adolescentes asuman un comportamiento pro-social. La deshumanización de la víctima disminuye la probabilidad en un 45 % de comportamientos prosociales orientados a la complacencia u obediencia, y en un 61 % la probabilidad de conductas prosociales con motivación altruista.

Abstract The articles aims to describe the main prosocial motivations and cognitive mechanisms of moral disconnection, and to analyze the relationship between the two constructs in adolescents separated from illegal armed groups, located in the form of a substitute home Tutor of the Colombian Family Welfare Institute (ICBF), in Manizales, Colombia. It is a quantitative research, non-experimental cross-sectional design; descriptive-correlational scope study. A non-probabilistic sample composed of 35 adolescents was used. The instruments used were Revised Prosocial Trends Scale (PTM-R) and the Moral Disconnection Mechanisms Questionnaire (MMDS). As results it was determined that the prosocial trends with the highest average value were complacency and emergence. The most commonly used mechanisms of moral disconnection were attribution of guilt, moral justification and distortion of consequences. No significant differences were found between men and women. It was found significant correlations, of a negative sign, between the prosocial tendencies of complacency and altruism and the moral disconnection. Displacement of responsibility decreases by 34 % the likelihood that adolescents will engage in prosocial behaviour. Dehumanization of the victim decreases the probability by 45 % of prosocial behaviors oriented to complacency or obedience and, by 61 % the probability of prosocial behaviors with altruistic motivation.

Introducción. El fracaso de la extubación (FE) está asociado a mayor riesgo de neumonía, estadía hospitalaria y mortalidad. Objetivo. Determinar la prevalencia del FE e identificar factores asociados en nuestra población. Materiales y métodos. Diseño observacional y retrospectivo. Ingresaron todos los pacientes mayores de 1 mes hasta 18 años que, en el período 2012-2016, requirieron asistencia respiratoria mecánica más de 12 h, y al menos tuvieron una extubación programada durante su internación. Se registraron los aspectos relacionados con la ventilación y las causas de fracaso. Resultados. Se extubaron 731 pacientes y la prevalencia de FE fue del 19,3 %. Las causas de fracaso fueron la obstrucción alta de la vía aérea (51,4 %), fatiga muscular (20,1 %), depresión del centro respiratorio (14,6 %) e incapacidad de proteger la vía aérea (9,7 %). Los factores independientes para explicar el FE según el análisis multivariado fueron afección crónica compleja neurológica (odds ratio -#91;OR-#93;= 2,27; intervalo de confianza del 95 % -#91;IC-#93;= 1,21-4,26); infección respiratoria aguda baja en el paciente con una secuela previa (OR= 1,87; IC 95 %= 1,113,15); lesión neurológica aguda (OR= 1,92; IC 95 %= 1,03-3,57); extubación no planeada (OR= 2,52; IC 95 %= 1,02-6,21) y la presencia de estridor (OR= 5,84; IC 95%= 3,66-9,31). Conclusión. La principal causa de FE fue la obstrucción alta de la vía aérea. La secuela neurológica y la afección neurológica aguda, la extubación no planeada y la presencia de estridor posextubación fueron identificadas como factores de riesgo asociados al FE.

Introduction. Extubation failure (EF) is associated with a higher risk for pneumonia, hospital stay, and mortality. Objective. To determine the prevalence of EF and identify the associated factors in our population.Materials and methods. Observational and retrospective design. All patients aged 1 month old to 18 years old who required mechanical ventilation for more than 12 hours and underwent at least one scheduled extubation during their stay in the 2012-2016 period were included. The aspects related to ventilation and the causes of failure were recorded. Results. Seven hundred and thirty-one patients were extubated and the prevalence of EF was 19.3 %. The causes of failure included upper airway obstruction (51.4 %), muscle fatigue (20.1 %), respiratory center depression (14.6 %), and inability to protect the airways (9.7%). As per the multivariate analysis, the independent factors that accounted for EF were neurological complex chronic condition (odds ratio [OR] = 2.27; 95 % confidence interval [CI] = 1.21-4.26); acute lower respiratory tract infection in a patient with prior sequelae (OR = 1.87, 95 % CI = 1.11- 3.15); acute neurological injury (OR = 1.92, 95 % CI=1.03-3.57); unplanned extubation (OR =2.52, 95 % CI = 1.02-6.21), and presence of stridor (OR = 5.84, 95 % CI = 3.66-9.31). Conclusion. The main cause of EF was upper airway obstruction. Neurological sequelae, acute neurological injury, unplanned extubation, and the presence of postextubation stridor were identified as risk factors associated with EF

The corpus callosum is the largest white matter tract in the human brain, and its specific function is still unclear. Corpus callosum infarction is clinically rare, and its manifestations are complex and diverse. It is easy to miss and misdiagnose early. Corpus callosum infarction is often accompanied by other parts infarction, and the incidence of the infarction at the splenium of corpus callosum is the highest. Isolated corpus callosum infarction can be characterized by typical disconnection symptoms, such as apraxia, tactile disorder, Alien hand syndrome, visual deformity, etc. The prognosis of the corpus callosum infarction is generally better. This article reviews the etiology, clinical manifestations, imaging, differential diagnosis, and research status of treatment of corpus callosum infarction.

Repair effect of dental pulp stem cells on facial nerve injury in rabbits and its mechanism / 吉林大学学报(医学版)

Objective: To establish the rabbit facial nerve injury model by surgery and to explore the repair effect of dental pulp stem cells on the facial nerve injury in the rabbits, and to clarify its possible mechanism. Methods: The dental pulp stem cells were isolated, cultured and induced. A total of 45 rabbits were randomly divided into normal control group, model group and experiment group, and there were 15 rats in each group. Except for normal control group, the rabbits in the other groups were cut along the corner of mouth to the front of the ear to form a incision about 3 cm, the upper buccal branches were disconnected, and the facial nerve buccal injury models were established. After 1 week, 0. 1 mL dental pulp stem cell suspension (5×106) was injected into the operative cavity of the rats in experiment group, and the rabbits in normal control group did not receive any treatment. The rabbits in model group were injected with the same amount of phosphate buffer (PBS). Two weeks after operation, the behavior and movement function scores of facial beard of the rabbits in various groups were evaluated; the pathomorphology of facial nerve tissue of the rabbits in various groups was observed by HE staining; immunohistochemical staining was used to detect the number of brain derived nerve growth factor (BDNF) and ciliary neurotrophic factor (CNTF) positive cells; the number of regenerated nerve fibers, the diameter of fiber and the thickness of myelin sheath were observed under transmission electron microscope. Results: The primary dental pulp stem cells of young rabbits were successfully separated and identified. Most of them were fibroblast like and long fusiform. The HE staining results showed that the nucleus of the third generation of the dental pulp stem cells showed a dark blue and oval shape, and the spindle shaped hyperchromatic cells were fibroblast like cells. Compared with normal control group, the movement function score of facial beard of the rabbits in model group was significantly decreased (P

Objective To systematically evaluate the short-term outcomes of laparoscopic splenectomy and azygoportal disconnection (LSD) with open splenectomy and azygoportal disconnection (OSD) in the prevention and treatment of portal hypertension (PHT) hemorrhage.Methods A meta-analysis was conducted to evaluate the short-term outcomes published in randomized controlled studies and high quality casecontrolled studies on patients who underwent LSD or OSD from January 2006 to January 2016.Results 1 359 patients from 18 Chinese and English articles which met the inclusion criteria were included into this study.LSD and OSD were performed in 685 patients (the LSD group) and 674 patients (the OSD group),respectively.Meta-analysis showed that there was no significant difference in operation time between the LSD and OSD groups [MD=17.66,95％CI=(-2.46 ～37.78),P＞0.05].When compared with the OSD group,the LSD group had a shorter postoperative hospitalization stay [MD =-3.99,95％ CI =(-4.82 ～ -3.16),P ＜ 0.05],earlier postoperatively first passing of flatus [MD =-1.09,95％ CI =(-1.41 ～ -0.78),P ＜ 0.05],less intraoperative bleeding [MD =-272.66,95％ CI =(-345.11 ～-200.21),P ＜ 0.05],a lower complication rate [OR =0.34,95％ CI =(0.25 ～ 0.47),P ＜ 0.05],less postoperative pain [MD =-2.54,95％ CI =(-2.79 ～-2.29),P ＜ 0.05],shorter postoperative ambulation time [MD =-3.16,95％ CI =(-3.53 ～-2.79),P ＜ 0.05],less amount of peritoneal drainage [MD =-180.28,95％ CI =(-293.06 ～-67.49),P ＜0.05] and earlier recovery from postoperative loss in appetite [MD =-1.42,95％ CI =(-1.70 ～-1.13),P ＜ 0.05].Conclusion Compared with the traditional OSD,LSD had the advantages of less invasiveness,quicker recovery and higher quality of life in the perioperative period.LSD is the preferred operation for the prevention and treatment of PHT massive hemorrhage.

Sobre o feminino e os transtornos da procriação, ou a disjunção mulher-mãe / About the feminine and procreation disorders, or the woman-mother disconnection / A propos du féminin et des troubles de la procréation, ou la disjonction femme-mère / Sobre lo femenino y los trastornos de la procreación, o la disyunción mujer-madre

O artigo analisa o recurso, no discurso psicopatológico, a categorias diagnósticas para delimitar o que diverge da norma relativa ao que se espera da mulher no lugar de mãe. Discute-se, a partir da perspectiva em que a psicanálise aborda o tema do feminino, que a abordagem patologizante desconsidera justamente tal dimensão, na qual o feminino inclui, não como exceções à norma, o impasse frente à maternidade. Neste sentido, tal patologização denunciaria o horror por ele suscitado.

The article analyses the use of diagnostic categories in the psychopathological discourse to outline the boundaries between what is expected from a woman as a mother and what diverges from such expectation. Based on the perspective that the psychoanalysis addresses the topic of feminine, we discuss that the pathologizing approach disregards such dimension, in which the feminine includes, not as exceptions to the rule, the deadlock posed by maternity. In this regard, such pathologization would uncover the horror it arouses.

Cet article analyse l'utilisation, dans le discours psychopathologique, des catégories de diagnostic pour définir ce qui s'écarte de la norme par rapport à ce que l'on attend des femmes dans leur rôle de mère. Basé sur la perspective de la psychanalyse par rapport à la question du féminin, on affirme que l'approche de la pathologisation ne tient pas compte précisément de cette dimension dans laquelle le féminin comprend — non comme exception à la règle — la maladresse en ce qui concerne la maternité. En ce sens, cette pathologisation dénonce l'horreur qu'elle suscite.

El artículo analiza el recurso, en el discurso psicopatológico, y las categorías diagnósticas para delimitar lo que diverge de la norma relativa a lo que se espera de la mujer en el papel de madre. Se discute, desde la perspectiva en la que el psicoanálisis aborda el tema de lo femenino, que el abordaje patologizante desconsidera, justamente, tal dimensión, en la cual lo femenino incluye, no como excepciones a la norma, el impasse frente a la maternidad. En este sentido, tal patologización denunciaría el horror por él suscitado.

Der vorliegende Artikel analysiert die Verwendung von diagnostischen Kategorien im psychopathologischen Diskurs, um das zu definieren, was sich von der Norm abhebt, welche bestimmt was von der Frau in ihrer Mutterrolle erwartet wird. Basierend auf der psychoanalytischen Sicht des Weiblichen wird die Auffassung vertreten, dass der pathologisierende Ansatz gerade diese Dimension ignoriert, in der das Weibliche die Zweifel an der Mutterschaft beinhaltet, und zwar nicht als Ausnahme zur Norm. In diesem Sinn verrät diese Pathologisierung den von ihnen erzeugte Abscheu.

Transient Gerstmann syndrome as manifestation of stroke: Case report and brief literature review / Síndrome de Gerstmann transitória como manifestação de acidente vascular encefálico: relato de caso e breve revisão de literatura

ABSTRACT Gerstmann Syndrome (GS) is a rare neurological condition described as a group of cognitive changes corresponding to a tetrad of symptoms comprising agraphia, acalculia, right-left disorientation and finger agnosia. It is known that some specific brain lesions may lead to such findings, particularly when there is impairment of the angular gyrus and adjacent structures. In addition, the possibility of disconnection syndrome should be considered in some cases. The purpose of this article is to report a case of a young, cardiac patient, non-adherent to treatment, who presented with a stroke in which transient clinical symptoms were compatible with the tetrad of GS. The case report is followed by a discussion and brief review of the relevant literature.

RESUMO A síndrome de Gerstmann (SG) é uma condição neurológica rara, caracterizada por um grupo de alterações cognitivas que correspondem a uma tétrade composta por agrafia, acalculia, desorientação direita-esquerda e agnosia para dedos. Sabe-se que certas lesões encefálicas específicas podem levar a tais achados, particularmente quando ocorre acometimento do giro angular e estruturas adjacentes. Além disso, a possibilidade de síndrome de desconexão deve ser considerada em alguns casos. O propósito deste artigo é relatar o caso de um paciente jovem cardiopata e não aderente ao tratamento que se apresentou com uma síndrome encéfalo-vascular associada a alterações clínicas transitórias compatíveis com a tétrade da SG. Este relato de caso é acompanhado de discussão e breve revisão de dados pertinentes da literatura.

Design of interlocking-style vascular shunt device and its in vitro experiment / 医疗卫生装备

Objective To develop an interlocking-style vascular shunt device for the treatment of distal limb ischemia resulting from vascular disconnection and defect.Methods A one-way interlocking buckle was designed with the space between the clamping teeth being 0.5 mm,which prevented the device from moving backwards and fixed the vessel and shunt tube conveniently.The interlocking buckle combined with silicone tube was used to connect the two ends of the defected vessel,which was compared with conventional method by suture ligation and silicone tube by the tests on vessel bursting pressure and tensile biomechanics.Results The vessel repaired with the developed device behaved better than that by the conventional method in the tests on vessel bursting pressure and tensile biomechanics (P＜0.05).Conclusion The vascular shunt device can be used for the treatment of distal limb ischemia resulting from vascular disconnection and defect,and thus facilitates the vascular graft in rear hospital after evacuation.

Self-made single-port and three port retroperitoneoscopic renal pedicle lymphatic disconnection for chyluria / 中国内镜杂志

Objective To explore the clinical safety and efficacy of self-made single-port retroperitoneoscopic renal pedicle lymphatic disconnection for chyluria. Methods From Feb 2013 to Mar 2016, clinical data of 34 patients were collected. Of them, 16 cases underwent self-made single-port retroperitoneoscopic renal pedicle lymphatic disconnection and 18 cases underwent three port retroperitoneoscopic renal pedicle lymphatic disconnection. No significant difference was shown in age, body mass index between the two groups (P > 0.05). Mean operative time, estimated bleeding volume, drainage time, postoperative hospital stay, postoperative pain evaluation, satisfaction scores of incision were compared between the two groups. Results All procedures were successfully performed without conversion to open surgery. Compared with the three port surgery group, results in the single-port group were superior in terms of mean operative time [(102.3 ± 16.1) versus (132.4 ± 21.6) min, P < 0.05], there were no significant differences in estimated blood loss, drainage time, postoperative hospital stay, the date in postoperative pain evaluation, satisfaction scores of incision shown that single-port group was superior to three port group. Conclusion Our initial experience revealed that single-port retroperitoneoscopic renal pedicle lymphatic disconnection was a safe, effective, cost-effective and less-invasive procedure for chyluria with improved postoperative pain and cosmetic results.

Application of the arterial approach in laparoscopic pancreatoduodenectomy / 中华消化外科杂志

Pancreaticoduodenectomy is the main treatment method for pancreatic head carcinoma and periampullary cancer,and is also the only possible cure way.With the development of minimally invasive surgery,laparoscopic pancreaticoduodenectomy has been widely carried out,it even has been the routine operation in some pancreatic surgery center.The traditional approach is still the main approach for laparoscopic pancreaticoduodenectomy.In recent years,the procedure of the artery approach with its advantages has been put forward and gradually developed in laparoscopic pancreaticoduodenectomy through the continuous study and exploration.On the basis of the early arterial approach,authors' center established an artery preferential disconnection procedure in laparoscopic pancreaticoduodenectomy,which has been named arterial first approach.In the clinical practices and studies,this procedure also represents its unique advantages.
