ABSTRACT

Objective:To compare the short-term clinical effect of gastrointestinal or enterointestinal dominant channels after radical proximal gastrectomy combined with dual-channel anastomosis for upper gastric cancer.Methods:A total of 72 patients in Hefei Second People's Hospital from Jan 2017 to Jul 2021 were retrospectively analyzed, including 29 patients in the total gastrectomy group, and 43 patients in the group of radical proximal gastrectomy+dual-channel anastomosis, and by imaging results it was futher stratified into gastrointestinal dominant channel sub-group (26 cases) and intestinal dominant channel sub-group (17 cases).Results:The number of lymph node dissection in the total gastrectomy group was more than that in the proximal stomach group (27.9±3.2 vs. 25.4±2.9, t=3.441, P<0.05). While the 12 months post operation albumin [(36.1±2.4) g/L vs. (34.1 ± 2.3) g/L, t=3.526, P=0.001], hemoglobin [(122.9 ± 6.9) g/L vs. (115.9 ± 6.0) g/L, t=4.444, P=0.000], vitamin B12 [(349.0±21.7) pmol/ml vs. (77.9±8.5) pmol/ml, t=63.931, P=0.000] level, and the body mass index [(23.01±0.78) kg/m 2vs. (21.95±0.67) kg/m 2, t=5.978, P=0.000] decline level was unfavored ( P<0.05). The 12 months post operation vitamin B12 level, body mass index, albumin and hemoglobin level had no statistical difference in the two subgroups of proximal gastrectomy (all P>0.05). Conclusions:Laparoscopic proximal gastrectomy with double tract reconstruction for proximal gastric cancer is safe and reliable, which can effectively improve the postoperative nutritional status, prevent postoperative anemia.

ABSTRACT

Objective:To explore the uptake characteristics and temporal changes of 68Ga-fibroblast activation protein inhibitors (FAPIs) and 18F-FDG in the anastomotic site of reconstructed digestive tracts after radical surgery for gastrointestinal adenocarcinoma. Methods:A cohort of 43 patients (28 males, 15 females; age range 28-79 years) who underwent radical surgery for gastrointestinal adenocarcinoma and underwent 18F-FDG PET/CT follow-up between November 2020 and June 2022 in the First Affiliated Hospital of the Air Force Medical University was prospectively included. One week after the 18F-FDG PET/CT examination, 68Ga-FAPI-04 PET/CT imaging was performed. ROIs were drawn on the PET images at the highest uptake level of anastomotic sites of reconstructed digestive tract and abdominal wall incisions, and SUV max and target-to-background ratio (TBR) were determined. χ2 test, one-way analysis of variance, Kruskal-Wallis rank sum test (Bonferroni correction) and Wilcoxon signed-rank test were supplied. Results:There were 86 surgical wounds (13 gastric-intestinal anastomotic sites, 14 esophagus-intestinal anastomotic sites, 16 intestinal-intestinal anastomotic sites, and 43 abdominal wall incisions) included. In 68Ga-FAPI-04 PET imaging, SUV max of gastric-intestinal anastomotic sites was higher than that of abdominal wall incisions, with a statistically significant difference (adjusted P=0.014). The TBR did not show statistically significant differences among different types of surgical wounds ( H=3.88, P=0.275). In 18F-FDG PET imaging, SUV max of gastric-intestinal, esophagus-intestinal, and intestinal-intestinal anastomotic sites were all higher than that of abdominal wall incisions, with statistically significant differences (adjusted all P<0.001). There were no statistically significant differences in TBR among different types of surgical wounds ( H=3.02, P=0.388). In 68Ga-FAPI-04 PET imaging, the TBR of all types of anastomotic sites exhibited a decreasing trend with increasing postoperative time. Except for intestinal-intestinal anastomotic sites, the differences in TBR between < 0.5-year and ≥ 1.5-year groups were statistically significant for other types of surgical wounds (adjusted P<0.05). In 18F-FDG PET imaging, the TBR of abdominal wall incisions showed a decreasing trend with increasing postoperative time. However, the TBR of other types of surgical wounds did not show a decreasing trend, and the differences in TBR among different time groups were not statistically significant ( H values: 0.53-2.75, P values: 0.252-0.768). In comparing the two PET imaging agents, for all surgical wounds within the <0.5-year and 0.5-1.5-year groups, the 68Ga-FAPI-04 TBR was consistently higher than the 18F-FDG TBR ( z values: -3.17 and -2.55, P values: 0.002 and 0.011). However, in the ≥1.5-year group, the TBR values tended to be consistent, and the differences were not statistically significant ( z=-0.70, P=0.485). Conclusions:The 18F-FDG uptake in the anastomotic sites of reconstructed digestive tracts reaches a low level under half a year after surgery and does not significantly change over time, while the 68Ga-FAPIs uptake remains relatively high within the first 1.5 years after surgery but decreases over time. These patterns suggest that clinical attention should be paid to the differential diagnosis of anastomotic inflammation or fibrosis, which resulting in agent uptake and local tumor recurrence.

ABSTRACT

Introdução: A microcirurgia reparadora é ramo hoje indissociável e imprescindível na cirurgia plástica. O treinamento é longo, custo financeiro relativamente alto e exige muito dos proponentes. Para melhorar essa equação a favor da formação de novos microcirurgiões no Brasil, é fundamental facilitar o acesso ao treinamento experimental, utilizando materiais simples. Huaraca descreveu uma técnica utilizando um simples fio mononylon 5-0 para substituir o clamp vascular, que é instrumento indispensável da anastomose microcirúrgica e geralmente de alto custo. O objetivo é comparar a técnica de Huaraca com fio de mononylon e o clamp metálico tradicional durante anastomose microcirúrgica vascular. Métodos: Seis ratos da raça Wistar cujas duas artérias femorais foram aleatoriamente selecionadas para sutura término-terminal após secção completa, sendo um dos lados realizado com clamp vascular habitual e o contralateral com técnica de Huaraca, no mesmo tempo cirúrgico e pelo mesmo cirurgião. Resultados: Em ambas as situações, a taxa de patência foi de 67% após 72 horas, sendo que o tempo médio foi de 26 minutos com a técnica de Huaraca e de 18 minutos com o clamp tradicional (p=0,001). Conclusão: Apesar do tempo de execução mais longo, a técnica de Huaraca é medida simples e de baixo custo que pode substituir o clamp vascular tradicional.


Introduction: Reconstructive microsurgery is now an inseparable and essential branch of plastic surgery. The training is long, has a relatively high financial cost and requires a lot of the proponents. To improve this equation in favor of the formation of new microsurgeons in Brazil, it is essential to facilitate access to experimental training, using simple materials. Huaraca described a technique using a simple 5-0 mononylon thread to replace the vascular clamp, which is an indispensable instrument for microsurgical anastomosis and is generally expensive. The objective is to compare the Huaraca technique with mononylon thread and the traditional metal clamp during vascular microsurgical anastomosis. Methods: Six Wistar rats whose both femoral arteries were randomly selected for end-to-end suture after complete section, with one side performed with usual vascular clamp and the contralateral with Huaraca technique, at the same surgical time and by the same surgeon. Results: In both situations, the patency rate was 67% after 72 hours, with an average time of 26 minutes with the Huaraca technique and 18 minutes with the traditional clamp (p=0.001). Conclusion: Despite the longer execution time, the Huaraca technique is a simple and low-cost measure that can replace the traditional vascular clamp.

ABSTRACT

RESUMEN Introducción: El manejo inicial de neonatos con tetralogía de Fallot (TF), con síntomas asociados a una anatomía desfavorable y un flujo vascular pulmonar significativamente reducido es controversial, y un desafío clínico. Objetivo: Describir la evolución clínica y comparar el crecimiento de ramas pulmonares en neonatos con TF sintomáticos ingresados al Departamento de Cardiología del Hospital de Niños de Córdoba, desde marzo de 2011 hasta marzo de 2021, que recibieron anastomosis de Blalock-Taussig modificada (aBTm) versus colocación de stent en tracto de salida de ventrículo derecho (sTSVD). Material y métodos: Estudio retrospectivo, observacional. Se identificaron 113 pacientes con TF; 20 de ellos (18%) fueron neonatos sintomáticos y requirieron paliación inicial. Las variables categóricas se expresan como porcentaje; las continuas como mediana y rango intercuartilo (RIC). Un valor de p <0,05 se consideró significativo. Resultados: De los 20 pacientes incluidos en el estudio, 11 (55%) constituyen el grupo aBTm y 9 (45%) el grupo sTSVD. En el grupo aBTm la rama pulmonar derecha (RPD) pre paliación tenía un score Z -3 (RIC 4,20), que aumentó a -1,6 (RIC 1,56) (p = 0,11) post intervención; y la rama pulmonar izquierda (RPI) un score Z -2,5 (RIC 4,8) que se incrementó a -1,80 (RIC 2,36) (p = 0,44). En el grupo sTSVD la RPD pre paliación tuvo un score Z -3,45 (RIC 3,83) que aumentó a - 2,5 (RIC 3,58) (p = 0,021) y la RPI un score Z -4,10 (RIC 2,51) que se incrementó a -2,00 (RIC 3,75) (p = 0,011). La saturación de O2 (SO2) pre intervención fue 75% (RIC 6), y aumentó a 87% (RIC 9) en el grupo aBTm (p = 0,005); e inicialmente fue 75% (RIC 16) y aumentó a 91% (RIC 13) en el grupo sTSVD (p = 0,008). La mediana de estadía hospitalaria post procedimiento fue 10 días (RIC 11) en el grupo aBTm, y 6 (RIC 2) en el grupo sTSVD (p= 0,095). Conclusiones: En neonatos con TF sintomáticos, ambas estrategias paliativas mejoran la condición clínica. En los que recibieron sTSVD, se objetivó un crecimiento mayor de las ramas pulmonares. Mayor número de casos y seguimiento más largo serán necesarios para confirmar estos hallazgos.


ABSTRACT Background: The initial management of neonate patients with tetralogy of Fallot (TOF) associated with an unfavorable anatomy and significantly reduced pulmonary vascular flow is controversial and continues to be a clinical challenge. Objective: The aim of this study was to describe the clinical evolution and to compare pulmonary artery branch development in symptomatic neonatal TOF patients who received a modified Blalock Taussig shunt (mBT) versus right ventricular outflow tract stent placement (RVOTs) at the Department of Cardiology, Hospital de Niños de Córdoba, between March 2011 and March 2021. Methods: A retrospective, observational study identified 113 patients with TOF, 20 of which (18%) were symptomatic neonates requqiring initial palliative intervention. Categorical variables are expressed as percentage and continuous variables as median and interquartile range (IQR). A p value <0.05 was considered significant. Results: Among the 20 patients included in the study, 11 (55%) formed the mBT group and 9 (45%) the RVOTs group. In the mBT group, pre-palliative procedure right pulmonary artery (RPA) Z score was -3 (IQR 4.20) and increased to -1.6 (IQR 1.56) (p = 0.11) and left pulmonary artery (LPA) Z score of -2.5 (IQR 4.8) increased to -1.80 (IQR 2.36) (p = 0.44). In the RVOTs group, RPA Z score prior to palliative intervention was -3.45 (IQR 3.83) and increased to -2.5 (IQR 3.58) (p = 0.021) and LPA Z score of -4.10 (IQR 2.51) to -2.00 (IQR 3.75) (p = 0.011). Pre-intervention peripheral O2 saturation of 75% (IQR 6) increased to 87% (IQR 9) in the mBT group (p= 0.005) and from initially 75% (IQR 16) to 91% (IQR 13) in the RVOTs group (p= 0.008). Mean hospital stay after the procedure was 10 days (IQR 11) in the mBT group and 6 days (IQR 2) in the RVOTs group (p= 0.095). Conclusions: In symptomatic neonates with TOF, both palliative strategies improved the clinical condition. In patients who received RVOTs, there was greater development of pulmonary artery branches. A larger number of cases and longer-term follow-up will be necessary to confirm these findings.

ABSTRACT

ABSTRACT - BACKGROUND: Although many methods have been defined for colonic anastomosis, anastomotic leak still remains important for sepsis control and successful healing. AIM: The purpose of this study was to compare the effects of conventional suture, polyglactin 910 mesh, and omental flap coverage on healing and anastomotic leak in experimental colonic anastomosis in rats. METHOD: This study was conducted on 18 Wistar rats and the animals were divided into three groups as follows: Group 1: primary suture group; Group 2: primary suture plus polyglactin 910 mesh group; and Group 3: primary suture plus omental flap coverage group. Groups were compared in terms of anastomotic bursting pressure, inflammation, fibroblastic activity, neovascularization, and collagen amount. RESULTS: There was a statistically significant difference in anastomotic bursting pressure between Groups 1 and 2 and between Groups 1 and 3 (p=0.004, p<0.05). There was a significant difference in fibroblastic activity between Groups 1 and 3 (p=0.011, p<0.05) and between Groups 2 and 3 (p=0.030, p<0.05). There was a significant difference in neovascularization and collagen between Groups 1 and 2 and between Groups 1 and 3 (p<0.05). CONCLUSION: This experimental study found that polyglactin 910 mesh and omental flap coverage for colocolic anastomoses improved the physical strength and healing of the anastomosis compared to conventional hand-stitched anastomoses. The polyglactin may be a safe alternative to 910 mesh in cases where the omental flap coverage cannot be used in the colonic anastomosis.


RESUMO - RACIONAL: Embora muitos métodos tenham sido definidos para anastomose colônica, a fistula anastomótica ainda permanece importante para o controle da sepse e a cura bem-sucedida. OBJETIVO: comparar os efeitos da sutura convencional, tela de poliglactina 910 e cobertura de retalho omental na cicatrização e extravasamento anastomótico em anastomose colônica experimental em ratos. MÉTODO: estudo realizado em 18 ratos Wistar, sendo os animais divididos em 3 grupos. Grupo 1: Grupo de sutura primária; Grupo 2: sutura primária com malha de poliglactina 910; Grupo 3: Grupo sutura primária com cobertura de retalho omental. Os grupos foram comparados em termos de pressão de ruptura anastomótica, inflamação, atividade fibroblástica, neovascularização e quantidade de colágeno. RESULTADOS: houve diferença estatisticamente significativa na pressão de ruptura da anastomose entre os Grupos 1 e 2 e os Grupos 1 e 3 (p=0,004, p<0.05). Houve uma diferença significativa na atividade fibroblástica entre os Grupos 1 e 3 (p=0,011, p<0.05) e os Grupos 2 e 3 (p=0,030, p<0.05). Houve uma diferença significativa na neovascularização e colágeno entre os Grupos 1 e 2 e entre os Grupos 1 e 3 (p<0,05, p<0.05). CONCLUSÃO: o estudo experimental demonstrou que a tela de poliglactina 910 e a cobertura do retalho omental para anastomoses colocólicas melhoraram a resistência física e a cicatrização da anastomose em comparação com as anastomoses suturadas manualmente convencionais. A poliglactina pode ser uma alternativa segura à tela 910 nos casos em que a cobertura do retalho omental não pode ser utilizada na anastomose colônica.

ABSTRACT

ABSTRACT - BACKGROUND: Several methods have been proposed for the reconstruction of digestive transit after pancreatoduodenectomy. Biliary anastomosis positioned before gastric anastomosis helps reduce postoperative reflux and cholangitis. AIMS: The objective of this study was to present the anatomical sequence of gastric and biliary continuity after pancreatoduodenectomy in patients with pancreatic tumor and to evaluate the short- and long-term results in an initial series of cases. METHODS: Two techniques were used: one with Roux-en-Y reconstruction and pancreaticojejunostomy and the other with a single jejunal loop and pancreatogastroanastomosis. In both the cases, the gastric anastomosis was placed performed before the biliary one. An analysis of demographic data, Wirsung's duct and common bile duct dilatation, the use of percutaneous drainage, and postoperative complications was carried out. RESULTS: A total of seven patients (four men and three women), with a mean age of 62 years, underwent surgery. All cases had Wirsung's duct and common bile duct dilatation. A percutaneous external biliary drainage was performed in four patients. There were three postoperative complications: one related to delayed gastric emptying and two related to wound infections. During a median follow-up of 12 months, no episode of cholangitis was recorded. CONCLUSIONS: Elevated percentages of cholangitis are reported in different reconstructions after pancreatoduodenectomy, and it is difficult to conclude reflux as the main etiology. The proposed gastric and biliary reconstructions show conforming results, facilitating posterior endoscopic access. Late follow-up and large number of cases may help assess whether the etiology of postoperative cholangitis is reflux or other factors unrelated to the order of the anastomoses.


RESUMO - RACIONAL: Múltiplas são as propostas de reconstrução do trânsito digestivo após as pancreadoduodenectomias. A anastomoses biliar posicionada antes da anastomose gástrica oferece argumentos de evitar refluxo e colangite pós-operatória. OBJETIVOS: apresentar a técnica de continuidade gástrica e biliar com sequência anatômica após pancreatoduodenectomia em portadores de adenocarcinoma de pâncreas e avaliar os resultados em uma série inicial de casos. MÉTODOS: Foram utilizadas duas técnicas, uma com reconstrução em Y de Roux e pancreaticojejunostomia e outra com alça única de jejuno e pancreatogastroanastomose. Em ambos, a anastomose gástrica foi colocada antes da biliar. E análise de dados demográficos, dilatação do ducto de Wirsung e ducto biliar comum, uso de drenagem percutânea e complicações pós-operatórias. RESULTADOS: Foram operados 7 doentes: 4 homens e 3 mulheres, com média de idade de 62 anos. Todos os casos apresentavam dilatação do ducto de Wirsung e ducto biliar comum. Em 4 dos casos foi realizada drenagem biliar externa percutânea. Ocorreram 3 complicações pós-operatórias, 1 esvaziamento gástrico retardado e 2 infecções de ferida operatória. Durante o acompanhamento médio de 12 meses, não foram registrados episódios de colangite. CONCLUSÕES: Porcentagens elevadas de colangite são relatadas nas diferentes reconstruções após pancreatodudenectomias, sendo difícil atribuir de forma absoluta o refluxo como a principal etiologia. As reconstruções gástrica e biliar propostas são mais harmoniosas, além de facilitar o acesso endoscópico posterior. Seguimento tardio e número maior de casos, pode esclarecer se a etiologia da colangite pós-operatória pode ser o refluxo ou a outros fatores não relacionados à ordem das anastomoses.

ABSTRACT

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left eye was used as control group. Results: After optic nerve resection and anastomosis, stable ERG amplitude of the right eye was lost after 302 seconds in group 1 and after 296 seconds on group 2. Left eye kept longer stable ERG amplitude curves. Conclusions: The animal model of whole eye transplantation was effective in describing a novel technique to be used in rabbits, with success of the anatomic procedure. Further studies will clarify the best anastomosis methods and maintenance of function of the receptor organ. Translational relevance: this animal model of whole eye transplantation provides a novel perspective for blind patients and the research models, since we describe a novel mammal animal model. This model can be used as basis of a human model of whole eye transplantation in future studies.


RESUMO Objetivo: Descrever uma técnica cirúrgica inovadora para transplante de olho em um modelo animal em coelhos. Métodos: Seis coelhos machos com Dutch Belted foram submetidos à orbitotomia lateral do olho direito, com ampla exposição da anatomia retrobulbar, dissecção do cone muscular, exposição e secção distal do nervo óptico seguida de anastomose por vicryl (Grupo 1) ou cola de fibrina (Grupo 2). O registro da eletrorretinografia foi realizado antes da secção do nervo óptico e a cada 30 segundos após, para monitorar a função da retina. O olho esquerdo foi usado como grupo controle. Resultados: Após a ressecção do nervo óptico, a estabilidade da amplitude da eletrorretinografia foi perdida no olho direito após 302 segundos no Grupo 1 e após 296 segundos no Grupo 2. O olho esquerdo manteve eletrorretinografia estável por períodos mais longos. Conclusão: O modelo animal de transplante total de olho foi eficaz em descrever uma nova técnica cirúrgica para ser utilizada em laboratório com coelhos, com sucesso do procedimento anatômico. Novos estudos esclarecerão os melhores métodos de anastomose e manutenção da função do órgão receptor.

ABSTRACT

Objective:To explore the postoperative biliary leakage and severe complication rate and its related risk factors of hepaticojejunostomy (HJ) for biliary disease.Methods:The clinical data of patients undergoing HJ for benign biliary diseases at the First Affiliated Hospital of Anhui Medical University from Jan 2003 to Dec 2017 were retrospectively analyzed. Multi-factor analysis was used to find a risk factor for postoperative bile leakage and severe complications.Results:Two hundred and eighty-three patients received HJ. The median age was 39 years.The short-term complication rate after surgery was 19.1% ( n=54), and the biliary leakage rate was 11.7% ( n=33), and the severe complication rate was 15.2% ( n=43). By multi-factor analysis: preoperative sepsis[ OR=3.875, 95% CI (1.583, 9.485), P=0.003], liver cirrhosis [ OR=3.212, 95% CI (1.001, 10.307), P=0.050], intraoperative blood loss≥400 ml [ OR=6.054, 95% CI (1.231, 29.781), P=0.027],postoperative hospitalization ≥9 days [ OR=6.738, 95% CI (2.287, 19.855), P=0.001] are the independent risk factors for postoperative bile leakage. Main bile duct stone[ OR=2.764, 95% CI (1.174, 6.510), P=0.020], preoperative sepsis [ OR=4.310, 95% CI (1.666, 11.149), P=0.003], intraoperative bleeding ≥400 ml [ OR=5.944, 95% CI (1.231, 29.781), P=0.022] and postoperative hospitalization ≥ 9 days [ OR=11.422, 95% CI (1.317, 49.859), P=0.001] are the independent risk factors for serious complications. Conclusions:HJ should be conducted when the sepsis was under control and sufficient bile drainage.The patients' condition should be comprehensively and accurately assessed before operation. The indications for partial hepatectomy need to be strictly defined.

ABSTRACT

Objective:To investigate the effect of optimizing perioperative measures on reducing postoperative gastric emptying disorder in gastrointestinal reconstruction after pancreaticoduodenectomy.Methods:The clinical data of 146 patients who underwent pancreaticoduodenectomy from Jan 2019 to Dec 2020 at the Department of Hepatobiliary and Pancreatic Surgery,the First Affiliated Hospital ,Anhui Medical University were analyzed retrospectively. Among them, 78 cases underwent traditional Billroth Ⅱ gastrojejunal anastomosis for gastrointestinal reconstruction, and 68 cases in the improvement group took optimization measures. The time to first postoperative flatus, time to oral intake, postoperative hospital stay and complications were observed.Results:The operation time in the control group was (351.4±71.6) min, less than that in the improved group (368.8±97.6) min, while the time [(9.9±6.5)d vs. (7.6±6.0)d] to first oral take and postoperative hospital stay [(20.7±8.6)d vs. (17.9±7.0)d] were significantly longer than those in the improved group. The incidence of postoperative gastric emptying disorder (19.2% vs. 7.4%) was significantly higher than that in the improved group ( P<0.05). There was no significant difference in postoperative time to first flatus and postoperative gastrointestinal bleeding between the two groups (all P>0.05). Conclusions:The measures of optimizing gastrointestinal reconstruction in the perioperative period of pancreaticoduodenectomy have obvious advantages in reducing gastric emptying disorder, promoting the recovery of gastrointestinal function and shortening the length of hospital stay.

ABSTRACT

Kasai portoenterostomy is the preferred treatment for biliary atresia. Age at Kasai portoenterostomy is an important factor affecting the prognosis of children with biliary atresia and avoiding liver transplantation. Choosing the appropriate surgical age, restoring good bile drainage, improving the native liver survival rate, and avoiding early liver transplantation are the items that clinicians have always been working on. The age at Kasai portoenterostomy was correlated with the jaundice clearance rate, native liver survival rate, and the incidence of postoperative cholangitis. This article systematically reviewed the research advances on the relationship between age at Kasai portoenterostomy and prognosis for biliary atresia, aiming to provide the basis for the ideal surgical age of Kasai.

ABSTRACT

Objective:To investigate feasibility, efficiency and safety of kissing pancreatojejunostomy after pancreatoduodenectomy.Methods:From Jan 2006 to Sep 2020, the clinical data of 267 patients undergoing pancreatoduodenectomy and kissing pancreatojejunostomy were retrospectively analyzed.Results:Grade B postoperative pancreatic fistula (POPF) occurred in 6.37%, Grade C POPF in 2.25% of patients. There was no mortality within 30 days postoperatively as to pancreatic fistula, by cut-off of pancreatic duct diameter at 3mm, there was no significant difference between two subgroups (15/140 vs. 8/127, P=0.20). also, when grouped by texture of the pancreas, no there was significant difference (20/194 vs. 3/73, P=0.11). Conclusions:Kissing pancreatojejunostomy is feasible and easy to perform. It also does not increase the POPF rate when applied to the pancreatojejunostomy with thin pancreatic duct and soft texture.

ABSTRACT

Objective:To study the single purse-string parachute suturing technique for pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy, and to determine its feasibility and safety.Methods:The clinical data of 71 patients who underwent laparoscopic pancreaticoduodenectomy using the single purse-string parachute suturing technique for pancreaticojejunostomy from October 2018 to October 2021 at the Second Hospital of Hebei Medical University were retrospectively analyzed. There were 41 males and 30 females, with age (59.1±9.7) years old. The operative time, intraoperative blood loss, complication rate and other data were analyzed.Results:All 71 patients successfully underwent total laparoscopic pancreaticoduodenectomy, with 5 patients who underwent 2D laparoscopic surgery and 66 patients 3D laparoscopic surgery. There were additional vascular resection and reconstruction in 2 patients. The operative time was (388.9±92.9) min, the intraoperative blood loss was (411.3±176.9) ml, and the postoperative hospital stay was (14.1±5.8) d. The operation time of 71 patients who underwent the single purse-string parachute technique of pancreaticojejunostomy was (26.9±6.8) min. Postoperative complications occurred in 18 patients (25.4%). Grade B pancreatic fistula occurred in 2 patients (2.8%), and the longest time for removal of abdominal drain was 17 days after operation. Among the 71 patients, complications including biliary fistula occurred in 6 patients (8.5%), delayed gastric emptying in 5 patients (7.0%), pulmonary infection in 4 patients (5.6%), non-pancreatic fistula-related abdominal infection in 4 patients (5.6%), non-pancreatic fistula-related abdominal bleeding in 1 patient (1.4%), biliary tract bleeding in 1 patient (1.4%), and chylous leakage in 2 patients (2.8%).Conclusion:The single purse-string parachute technique of pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy had the advantages of being safe and reliable. The procedure is worthy of furthers promotion.

ABSTRACT

Objective:To compare the clinical outcomes of a double purse-string and bridging technique versus duct-to-mucosal pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of patients who underwent laparoscopic pancreaticoduodenectomy using the double purse-string and bridging pancreaticojejunostomy technique versus those who underwent duct-to-mucosa pancreaticojejunostomy at the Affiliated Jinhua Hospital of Zhejiang University School of Medicine from January 2016 to August 2021 were retrospectively analyzed. Of the 93 patients who underwent laparoscopic pancreaticoduodenectomy, there were 48 males and 45 females, with age of (62±10) years old. These patients were divided into two groups: patients who underwent double purse-string and bridging pancreaticojejunostomy (the double purse-string group, n=51), and patients who underwent duct-to-mucosa pancreaticojejunostomy (the duct-to-mucosa group, n=42). The clinical data of the two groups were compared. Results:All the 93 patients underwent laparoscopic pancreaticoduodenectomy successfully, and there were no deaths within 3 months of operation. Compared with the duct-to-mucosa group, the double purse-string group had significantly shorter time of pancreaticojejunal anastomosis [(32.41±8.75) vs. (47.62±8.90) min] and time of operation [(365.75±43.74) vs. (389.07±45.31) min] (all P<0.05). The postoperative pancreatic fistula rates were 9.8% (5/51) in the double purse-string group and 7.1% (3/42) in the duct-to-mucosa group. There was no significant difference between the two groups ( P>0.05). In the double purse-string group, there were 18 patients with a pancreatic duct diameter >3 mm, and 3 of these patients developed grade B pancreatic fistula, giving a grade B pancreatic fistula rate of 16.6% (3/18). In the duct-to-mucosa group, there were 11 patients with a pancreatic duct diameter >3 mm, and no patients developed grade B pancreatic fistula, giving a pancreatic fistula rate of 0(0/11). Conclusion:Compared with the duct-to-mucosa anastomosis, the double purse string and bridging pancreaticojejunostomy was technically simpler. It shortened the time of pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy, especially for patients with a non-dilated pancreatic duct.

ABSTRACT

Abstract Introduction: End-to-end anastomosis and extended end-to-end anastomosis are typically used as surgical approaches to coarctation of the aorta (CoAo) with access at the subclavian artery or an interposition graft. The objective of this study is to analyze the impact of surgical and anatomical characteristics and techniques on early outcomes after surgical treatment of CoAo without cardiopulmonary bypass through left thoracotomy. Methods: This is a quantitative, observational, and cross-sectional analysis of patients who underwent repair of CoAo between July 1, 2010 and December 31, 2017. Seventy-two patients were divided into three groups according to age: 34 in group A (≤ 30 days), 24 in group B (31 days to one year), and 14 in group C (≥ 1 year to 18 years). Results: Aortic arch hypoplasia was associated in 30.8% of the cases, followed by ventricular septal defect (13.2%). The preductal location was more frequent in group A (73.5%), ductal in group B (41.7%), and postductal in group C (71.4%). Long coarcted segment was predominant in groups A and C (61.8% and 71.4%, respectively) and localized in group B (58.3%). Extended end-to-end anastomosis technique was prevalent (68%), mainly in group A (91.2%). Mortality in 30 days was 1.4%. Conclusion: Most of the patients were children under one year of age, and extended end-to-end anastomosis was the most used technique, secondary to arch hypoplasia. Further, overall mortality was low in spite of moderate morbidity in the first 30 postoperative days.

ABSTRACT

Abstract Damage control has well-defined steps. However, there are still controversies regarding whom, when, and how re-interventions should be performed. This article summarizes the Trauma and Emergency Surgery Group (CTE) Cali-Colombia recommendations about the specific situations concerning second interventions of patients undergoing damage control surgery. We suggest packing as the preferred bleeding control strategy, followed by unpacking within the next 48-72 hours. In addition, a deferred anastomosis is recommended for correction of intestinal lesions, and patients treated with vascular shunts should be re-intervened within 24 hours for definitive management. Furthermore, abdominal or thoracic wall closure should be attempted within eight days. These strategies aim to decrease complications, morbidity, and mortality.


Resumen El control de daños es uno de los pilares de la cirugía de trauma. Sin embargo, la reintervención aún genera controversias en cuanto a quién, cuándo y cómo debe realizarse. El presente artículo presenta las recomendaciones del grupo de Cirugía de Trauma y Emergencias (CTE) de Cali, Colombia, respecto a las reintervenciones después de una cirugía de control de daños. Se recomienda el empaquetamiento como la estrategia de control de sangrado y se debe desempaquetar en un lapso entre 48 y 72 horas. La anastomosis diferida debe ser la opción de reparo en las lesiones intestinales. La reintervención vascular en los pacientes manejados con shunt vascular debe ser antes de las 24 horas para dar el manejo definitivo. En un lapso de 8 días se debe intentar realizar el cierre de la pared abdominal o torácica. Estas estrategias buscan disminuir la frecuencia de complicaciones y de morbimortalidad.

ABSTRACT

Abstract Damage control surgery is based on temporal control of the injury, physiologic recovery and posterior deferred definitive management. This strategy began in the 1980s and became a formal concept in 1993. It has proven to be a strategy that reduces mortality in severely injured trauma patients. Nevertheless, the concept of damage control in non-traumatic abdominal pathology remains controversial. This article aims to gather historical experiences in damage control surgery performed in non-traumatic abdominal emergency pathology patients and present a novel management algorithm. This strategy could be a surgical option to treat hemodynamically unstable patients in catastrophic scenarios such as hemorrhagic and septic shock caused by peritonitis, pancreatitis, acute mesenteric ischemia, among others. Therefore, damage control surgery is light amid better short- and long-term results.


Resumen La cirugía de control de daños es una estrategia de control temporal del daño tisular y recuperación fisiológica para un manejo definitivo diferido. Esta estrategia tiene antecedentes en el mundo del trauma desde la década de 1980, hasta su formalización conceptual en 1993. Hasta el momento ha demostrado ser una estrategia factible y que reduce la mortalidad en los pacientes críticamente enfermos. Sin embargo, el manejo de patologías abdominales no traumáticas aun es tema de discusión sobre su factibilidad y seguridad. El presente articulo tiene como objetivo realizar un relato histórico y experiencias en la aplicación de la cirugía de control de daños en emergencias quirúrgicas abdominales no asociadas a trauma y presentar un algoritmo de manejo usando los principios de la cirugía de control de daños. La aplicabilidad del control de daños en no trauma se enfrenta a los contextos de shock hemorrágico y séptico para patologías como peritonitis generalizada, peritonitis postquirúrgica, pancreatitis, isquemia mesentérica aguda, entre otras. Se ha demostrado que el uso de control de daños representa una luz para el cirujano ante la tormenta de la incertidumbre de la descompensación metabólica en el manejo de emergencias abdominales, para crear un puente para su manejo definitivo y permitir anastomosis como estrategia de reconstrucción intestinal y mejorar los resultados a corto y largo plazo.

ABSTRACT

In patients with abdominal trauma who require laparotomy, up to a quarter or a third will have a vascular injury. The venous structures mainly injured are the vena cava (29%) and the iliac veins (20%), and arterial vessels are the iliac arteries (16%) and the aorta (14%). The initial approach is performed following the ATLS principles. This manuscript aims to present the surgical approach to abdominal vascular trauma following damage control principles. The priority in a trauma laparotomy is bleeding control. Hemorrhages of intraperitoneal origin are controlled by applying pressure, clamping, packing, and retroperitoneal with selective pressure. After the temporary bleeding control is achieved, the compromised vascular structure must be identified, according to the location of the hematomas. The management of all lesions should be oriented towards the expeditious conclusion of the laparotomy, focusing efforts on the bleeding control and contamination, with a postponement of the definitive management. Their management of vascular injuries includes ligation, transient bypass, and packing of selected low-pressure vessels and bleeding surfaces. Subsequently, the unconventional closure of the abdominal cavity should be performed, preferably with negative pressure systems, to reoperate once the hemodynamic alterations and coagulopathy have been corrected to carry out the definitive management.


En pacientes con trauma de abdomen que requieren laparotomía, hasta una cuarta o tercera parte, habrán sufrido una lesión vascular. Las estructuras venosas principalmente lesionadas son la vena cava y las iliacas, y de vasos arteriales, son las iliacas y la aorta. El abordaje de este tipo de heridas vasculares se puede ser difícil en el contexto de un paciente hemodinámicamente inestable ya que requiera medidas rápidas que permita controlar la exanguinación del paciente. El objetivo de este manuscrito es presentar el abordaje del trauma vascular abdominal de acuerdo con la filosofía de cirugía de control de daños. La primera prioridad en una laparotomía por trauma es el control de la hemorragia. Las hemorragias de origen intraperitoneal se controlan con compresión, pinzamiento o empaquetamiento, y las retroperitoneales con compresión selectiva. Posterior al control transitorio de la hemorragia, se debe identificar la estructura vascular comprometida, de acuerdo con la localización de los hematomas. El manejo de las lesiones debe orientarse a la finalización expedita de la laparotomía, enfocado en el control de la hemorragia y contaminación, con aplazamiento del manejo definitivo. Lo pertinente al tratamiento de las lesiones vasculares incluyen la ligadura, derivación transitoria y el empaquetamiento de vasos seleccionados de baja presión y de superficies sangrantes. Posteriormente se debe realizar el cierre no convencional de la cavidad abdominal, preferiblemente con sistemas de presión negativa, para consecutivamente reoperar una vez corregidas las alteraciones hemodinámicas y la coagulopatía para realizar el manejo definitivo.

ABSTRACT

RESUMEN Los trastornos pancreáticos, las pancreatitis agudas de etiología biliar son infrecuentes en pediatría y más aún los pseudoquistes pancreáticos, los cuales son colecciones líquidas rodeadas por una cápsula fibrosa sin epitelio, generalmente secundario a una pancreatitis aguda. Presentamos el caso de una paciente femenina de 14 años, con antecedente de pancreatitis aguda de origen biliar hace 10 meses, que presenta dolor abdominal y una masa palpable en epigastrio. Se realizaron estudios imagenológicos, confirmando el diagnóstico de pseudoquiste pancreático y colelitiasis. Se optó por las bondades técnicas y estéticas de la laparoscopía, para esta población. Por lo cual, se realizó una cistogastroanastomosis y colecistectomía laparoscópica, con una evolución favorable. Nosotros reafirmamos que esta técnica, es un método seguro y efectivo, para el manejo de esta patología en pacientes pediátricos, y debería considerarse como primera opción, al no contar con procedimientos endoscópicos. Siendo este, el primer reporte en nuestro medio.


ABSTRACT The pancreatic disorders, as acute pancreatitis, of biliary etiology are rare in pediatrics, even more the pancreatic pseudocysts. They are liquid collections surrounded of a fibrous capsule without epithelium, secondary to acute pancreatitis. We present the case of a 14-year-old female patient with a history of acute pancreatitis because of biliary etiology, 10 months prior. She complained of intermittent abdominal pain and a palpable mass in the epigastrium. The Imaging studies showed a pancreatic pseudocyst and cholelithiasis. The laparoscopy was chosen because the technical and esthetic benefits for this population. Therefore, a laparoscopic cystogastro-ostomy-anastomosis and cholecystectomy were performed, with good progress. We affirm this technique is a safe and effective method for the management of this pathology in pediatric patients, and it should be considered as the first option in case endoscopic procedures are not available. This is the first report in our settings.

ABSTRACT

Objective:To evaluate the effect of different superficial vascular patterns on pregnancy outcome and residual anastomosis following laser coagulation in placentae with twin-to-twin transfusion syndrome (TTTS).Methods:This study retrospectively collected and analyzed the clinical data and postnatal placenta perfusion characteristics of 57 cases of TTTS who received fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) and delivered at Peking University Third Hospital from April 2014 to April 2019. According to the vascular pattern, all the cases are divided into four groups, which were parallel, staggered, mixed, and monoamniotic groups. Differences in the operation time and method, pregnancy outcome, and residual vascular anastomosis between the four groups were compared using analysis of variance, non-parametric tests, and Chi-square (or Fisher's exact) tests. Results:Among the 57 cases, the staggered, mixed, parallel, and monoamniotic types were accounted for 68.4%(39/57), 15.8%(19/57), 14.0%(8/57), and 1.7%(1/57), respectively. After exclusion of one case of monoamniotic type, gestational weeks at onset and surgery in the parallel group were both later than the staggered and mixed groups [23.0 (22.0-26.3) weeks vs 21.0 (17.0-24.7) weeks and 22.6 (21.3-23.9) weeks, H=10.306, P=0.006; 25.0 (22.6-26.3) weeks vs 22.0 (17.4-24.9) weeks and 23.2 (22.4-24.0) weeks, H=9.926, P=0.007; all P'<0.016 7]. There was no statistical significance in the differences in operation time and method, gestational age at the end of the pregnancy, neonatal birth weight, or birth weight discordance between the three groups. The diameter of residual vascular anastomosis of women in the staggered group was less than that in the mixed group [0.6 (0.1-5.0) mm vs 1.4 (0.3-5.1) mm, P'<0.016 7], but no significant difference was observed in the parallel-group [0.9 (0.2-3.6) mm] neither with the mixed or staggered group. The staggered group was noted for an increased distance ratio of umbilical cord insertion compared with the parallel and the mixed group [0.66 (0.59-1.00) vs 0.49 (0.25-0.55) and 0.48 (0.42-0.53); P'<0.016 7]. There was no significant difference between the parallel and the mixed groups. Conclusions:Placental superficial vascular patterns may affect the residual vascular anastomosis in women with TTTS following FLOC, which should be thoroughly evaluated before the operation to develop an individual management plan to reduce residual anastomosis incidence.

ABSTRACT

Objective:To evaluate clinical characteristics and treatment of postoperative anastomotic stricture in pediatric congenital biliary dilatation patients.Methods:The clinical data of 24 children with postoperative anastomotic stricture from Apr 2012 to Oct 2019 in Beijing Children's Hospital was retrospectively analyzed.Results:There were 6 males and 18 females. Patients were divided into bile- leak group (BL, n=6) and non bile-leak group (NBL, n=18) based on whether there was anastomotic leakage after primary surgery. The main symptoms in BL group was persistent obstructive jaundice, and recurrent cholangitis in NBL group. Postoperative symptoms were first shown in an average of 7.0 months in BL group, compared to 59.0 months in NBL group, P<0.05. In BL group, 4 underwent redoing hepaticojejunostomy, 2 underwent anastomosis plasty. In NBL group, 3 underwent redoing hepaticojejunostomy, 15 did anastomosis plasty with multiple biliary stones found necessitating extraction. After reoperation, one patient had bile leakage, 2 patients had recurrent cholangitis within one-month, 21 patients had uneventful recovery. Five were found to have biliary stones in long-term follow-up. Conclusions:Biliary-enteric anastomotic leakage can cause stricture in postoperative patients of congenital biliary dilatation ,reoperation is necessary in symptomatic patients.
