Edema pulmonar por reexpansión. Reporte de Caso / Pulmonary edema due to re-expansion. Case Report

Introducción. El edema pulmonar por reexpansión es una complicación poco frecuente, secundaria a una rápida reexpansión pulmonar posterior al drenaje por toracentesis o toracostomía cerrada. Al día de hoy, se ha descrito una incidencia menor al 1 % tras toracostomía cerrada, con mayor prevalencia en la segunda y tercera década de la vida. Su mecanismo fisiopatológico exacto es desconocido; se ha planteado un proceso multifactorial de daño intersticial pulmonar asociado con un desequilibrio de las fuerzas hidrostáticas. Caso clínico. Presentamos el caso de un paciente que desarrolló edema pulmonar por reexpansión posterior a toracostomía cerrada. Se hizo una revisión de la literatura sobre esta complicación. Resultados. Aunque la clínica sugiere el diagnóstico, la secuencia de imágenes desempeña un papel fundamental. En la mayoría de los casos suele ser autolimitado, por lo que su manejo es principalmente de soporte; sin embargo, se han reportado tasas de mortalidad que alcanzan hasta el 20 %, por tanto, es importante conocer los factores de riesgo y las medidas preventivas. Conclusión. El edema pulmonar de reexpansión posterior a toracostomía es una complicación rara en los casos con neumotórax, aunque es una complicación que se puede presentar en la práctica diaria, por lo cual debe tenerse en mente para poder hacer el diagnóstico y un manejo adecuado.

Introduction. Re-expansion pulmonary edema is a rare complication secondary to rapid pulmonary re-expansion after drainage by thoracentesis and/or closed thoracostomy. As of today, an incidence of less than 1% has been described after closed thoracostomy, with a higher prevalence in the second and third decades of life. Its exact pathophysiological mechanism is unknown; a multifactorial process of lung interstitial damage associated with an imbalance of hydrostatic forces has been proposed. Clinical case. We present the case of a patient who developed pulmonary edema due to re-expansion after closed thoracostomy, conducting a review of the literature on this complication. Results. Although the clinic suggests the diagnosis, the sequence of images plays a fundamental role. In most cases, it tends to be a self-limited disease, so its management is mainly supportive. However, mortality rates of up to 20% have been recorded. Therefore, it is important to identify patients with major risk factors and initiate preventive measures in these patients. Conclusions. Re-expansion pulmonary edema after thoracostomy is a rare complication in cases with pneumothorax; however, it is a complication that can occur in daily practice. Therefore, it must be kept in mind to be able to make the diagnosis and an adequate management.

Postoperative complications and related risk factors in COVID-19 patients / 基础医学与临床

The incidence of postoperative multi-system complications,such as pulmonary complications and sep-sis,as well as mortality of patients with COVID-19.Therefore,patients with COVID-19 should be fully recovered before elective surgery and a minimum of 7 weeks recovery time is routinely recommen-ded.At the same time,the occurrence of adverse outcomes such as postoperative complications in patients with COVID-19 should be consid-ered in a multidimensional manner,taking into account the related risk factors such as age,severity of the dis-ease,type of surgery,anesthesia method,underlying comorbidities,type of viral strain,vaccination status and other related risk factors.

Prognosis of congenital bile duct cysts after cyst resection and risk factors analysis of postoperative biliary calculus / 中华肝胆外科杂志

Objective:To study the prognosis of congenital bile duct cysts following cyst resection, and to analyze the risk factors associated with the development of postoperative biliary calculus.Methods:Clinical data of 149 patients with congenital bile duct cysts undergoing surgery in the First Affiliated Hospital of Nanjing Medical University from May 2004 to January 2022 were retrospectively analyzed, including 59 males and 90 females, with a median age of 32 (21, 47) years old. Patients were divided into two groups: the stone group ( n=51, biliary calculus occurred during the follow-ups after surgery) and non-stone group ( n=98). Clinical data such as gender, age, medical history, cyst type, biliary calculus, anastomotic stenosis and occurrence of cancer were compared. All patients were followed up via telephone consultations. A logistic regression analysis was used to identify the risk factors associated with the occurrence of biliary calculus after surgery. Results:The duration of the follow-ups was 120 (24, 211) months. The observed incidence of postoperative biliary calculus, anastomotic stricture, and cancer in the patients were 34.2% (51/149), 8.7% (13/149), and 4.7% (7/149), respectively. The logistic regression analysis indicated that incomplete cyst resection ( OR=3.332, 95% CI: 1.221-9.094) and postoperative anastomotic stenosis ( OR=13.300, 95% CI: 2.586-68.401) were associated with a higher risk of biliary calculus formation after cystectomy (all P<0.05). Conclusion:Patients with congenital bile duct cysts suffer a high risk of biliary calculus formation after cystectomy. The residual cyst and postoperative anastomotic stenosis are independent risk factors for biliary calculus after surgery.

Guidelines for clinical diagnosis and treatment of combined liver and kidney transplantation / 器官移植

Combined liver and kidney transplantation has been steadily applied in major transplantation centers, saving the lives of many patients with end-stage liver and renal failure. However, there are still multiple unresolved problems in the clinical diagnosis, treatment and long-term prognosis of combined liver and kidney transplantation. By referring to "Technical Operating Standards for Combined Liver and Kidney Transplantation (2019 Edition)" and the latest published literature and guidelines at home and abroad, "Guidelines for Clinical Diagnosis and Treatment of Combined Liver and Kidney Transplantation" was formulated. Recommendations and suggestions were delivered regarding the surgical indications and contraindications, preoperative preparation and evaluation, the timing of transplantation for end-stage liver and kidney diseases, the selection of surgical approaches and postoperative follow-up, specific pathophysiology, surgical techniques, complication management and immunosuppressive treatment of combined live and kidney transplantation, aiming to enhance the utilization rate of grafts and improve the survival and prognosis of combined liver and kidney transplant recipients.

Research progress in liver transplantation in patients with situs inversus totalis / 器官移植

Situs inversus totalis (SIT) is a rare congenital condition, with an extremely low incidence. There is no difference between SIT individuals without onset of diseases and healthy counterparts. However, when SIT individuals suffer from diseases, the diagnosis and treatment are highly challenging due to insufficient understanding of SIT populations, especially for those complicated with end-stage liver disease and requiring liver transplantation. It is a huge challenge for surgeons whether SIT individuals serve as donors or recipients of liver transplantation. In this article, recent case reports related to liver transplantation in SIT patients were summarized, and the development, key procedures, clinical prognosis and postoperative complications of liver transplantation in SIT patients were reviewed.

Viscotrabeculotomy with anterior chamber irrigation versus Ahmed glaucoma valve implantation for silicone oil glaucoma in the pseudophakic eye / Viscotrabeculotomia com irrigação da câmara anterior versus implante de válvula de Ahmed para glaucoma por óleo de silicone em olho pseudofácico

ABSTRACT Purpose: To compare viscotrabeculotomy with anterior chamber irrigation to Ahmed glaucoma valve implantation for secondary glaucoma following silicone oil removal. Methods: A prospective study was conducted on 43 vitrectomized pseudophakic eyes with persistent glaucoma after silicone oil removal. Patients were randomized to either viscotrabeculotomy with anterior chamber irrigation or Ahmed glaucoma valve implantation. All patients were examined on day 1, week 1, and months 1, 3, 6, 9, 12, 18, and 24 postoperatively. Postoperative complications were noted. Success was defined as an intraocular pressure between 6 and 20 mmHg and with an intraocular pressure reduction of >30% compared with the preoperative intraocular pressure. Results: There were 22 eyes in the viscotrabeculotomy with anterior chamber irrigation and 21 eyes in the Ahmed glaucoma valve implantation group. The mean preoperative and postoperative intraocular pressure in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 35.5 ± 2.6 mmHg and 35.5 ± 2.4 mmHg and 16.9 ± 0.7 mmHg and 17.9 ± 0.9 mmHg respectively (p˂0.0001). There was a statistically significant intraocular pressure reduction at all follow-up time points compared to preoperative values (p˂0.0001) in both groups. The unqualified success rate in the viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation groups were 72.73% and 61.9%, respectively. A minimal self-limited hyphema was the most common complication. Conclusions: Both viscotrabeculotomy with anterior chamber irrigation and Ahmed glaucoma valve implantation are effective in lowering the intraocular pressure in glaucoma after silicone oil removal with viscotrabeculotomy with anterior chamber irrigation providing greater reduction, higher success rates, and minimal complications.

RESUMO Objetivo: Comparar a viscotrabeculotomia com irrigação da câmara anterior com o implante de válvula de glaucoma de Ahmed para glaucoma secundário após remoção de óleo de silicone. Métodos: Foi realizado um estudo prospectivo de 43 olhos pseudofácicos vitrectomizados com glaucoma persistente após a remoção de óleo de silicone. Os pacientes foram randomizados para viscotrabeculotomia com irrigação da câmara anterior ou implante de válvula de Ahmed. Todos os pacientes foram examinados no primeiro dia, na primeira semana e 1, 3, 6, 9, 12, 18 e 24 meses após a cirurgia. Observaram-se complicações pós-operatórias. O sucesso foi definido como uma pressão intraocular entre 6 e 20 mmHg e uma redução da pressão intraocular >30% em comparação com a pressão intraocular pré-operatória. Resultados: Foram designados 22 olhos para o grupo da viscotrabeculotomia com irrigação da câmara anterior e 21 olhos para o grupo do implante de válvula de Ahmed. A pressão intraocular média pré-operatória foi de 35,5 ± 2,6 mmHg para o grupo da viscotrabeculotomia com irrigação da câmara anterior e pós- e de 35,5 ± 2,4 mmHg no grupo do implante de válvula de Ahmed. e Os valores pós-ope­ratórios foram de 16,9 ± 0,7 mmHg e 17,9 ± 0,9 mmHg para esses mesmos grupos, respectivamente (p<0,0001). Ambos os grupos tiveram uma redução estatisticamente significativa da pressão intraocular em relação aos valores pré-operatórios (p<0,0001) em todos os momentos do acompanhamento. A taxa de sucesso não qualificado nos grupos da viscotrabeculotomia com irrigação da câmara anterior e do implante de válvula de Ahmed foi de 72,73% e 61,9%, respectivamente. A complicação mais comum foi o hifema, autolimitado e mínimo. Conclusões: Tanto a viscotrabeculotomia com irrigação da câmara anterior quanto o implante de válvula de Ahmed são eficazes na redução da pressão intraocular no glaucoma após injeção de óleo de silicone, mas a viscotrabeculotomia com irrigação em câmara anterior proporcionou maior redução da pressão intraocular e maiores taxas de sucesso, com complicações mínimas.

Management of glaucoma with Boston type 1 keratoprosthesis / Manejo do glaucoma em olhos com ceratoprótese Boston tipo 1

ABSTRACT Purpose: To describe the frequency, clinical characteristics, complications, and management of glaucoma in eyes that underwent keratoprosthesis implantation. Methods: Patients who underwent keratoprosthesis surgery between June 2010 and January 2020 were retrospectively evaluated for glaucoma association and prognoses. Results: Among 17 patients who underwent keratoprosthesis surgery, 9 (52.9%) were associated with underlying or keratoprosthesis-induced glaucoma. Five eyes (29.4%) had underlying glaucoma and underwent a glaucoma drainage device implantation at least 6 months before keratoprosthesis surgery. One eye (5.9%) with normal intraocular pressure had glaucoma drainage device implantation at the same session with keratoprosthesis surgery due to high-risk characteristics of anterior segment structures. Four eyes with preexisting glaucoma showed progression after keratoprosthesis surgery. Additional antiglaucomatous treatment was commenced in two eyes whereas implantation of 2nd glaucoma drainage device was performed in two eyes. Postoperative complications in three eyes (100%) with glaucoma drainage device implanted 6 months before or at the same session with aphakic type keratoprosthesis surgery with partial vitrectomy included rhegmatogenous retinal detachment in two eyes and bacterial endophthalmitis in one eye. Migration of silicone oil through the tube to the subconjunctival area was seen after pars plana vitrectomy in one eye. None of the three eyes (0%) that underwent glaucoma drainage device implantation years before keratoprosthesis surgery experienced a posterior segment complication other than glaucomatous progression. Out of 11 eyes with no previous history of glaucoma, 3 (27.3%) showed high intraocular pressure and glaucomatous disc changes after keratoprosthesis surgery, which could be pharmacologically controlled. Conclusions: In this cohort, eyes with preexisting glaucoma were more difficult to manage compared to eyes with de novo glaucoma after keratoprosthesis surgery. Retinal complications appeared more often when glaucoma drainage device implantation was performed no more than 6 months before aphakic type keratoprosthesis surgery with partial vitrectomy.

RESUMO Objetivo: Descrever a frequência, as características clínicas, as complicações e o manejo do glaucoma em olhos submetidos a implantes de ceratoprótese. Métodos: Pacientes submetidos à cirurgia de ceratoprótese entre junho de 2010 e janeiro de 2020 foram avaliados retrospectivamente em termos de glaucoma associado e prognóstico. Resultados: Dos 17 pacientes submetidos à cirurgia de ceratoprótese, em 9 (52,9%) foi constatado glaucoma subjacente ou induzido por ceratoprótese. Cinco olhos (29,4%) tinham glaucoma subjacente e receberam a implantação de um dispositivo de drenagem de glaucoma pelo menos 6 meses antes da cirurgia de ceratoprótese. Um olho (5,9%) com pressão intraocular normal teve implantado um dispositivo de drenagem de glaucoma na mesma sessão da cirurgia de ceratoprótese, devido às características de "alto risco" das estruturas do segmento anterior. Quatro dos olhos com glaucoma preexistente apresentaram progressão após a cirurgia de ceratoprótese. Foi iniciado um tratamento antiglaucomatoso adicional em 2 olhos, enquanto outros 2 olhos receberam o implante de um segundo dispositivo de drenagem de glaucoma. Foram observadas complicações pós-operatórias em 3 olhos (100%) com dispositivo de drenagem de glaucoma implantado 6 meses antes ou na mesma sessão da cirurgia de ceratoprótese tipo afácica com vitrectomia parcial, incluindo descolamento de retina regmatogênico em 2 olhos e endoftalmite bacteriana em 1 olho. Em 1 olho observou-se migração do óleo de silicone para a área subconjuntival através do tubo após vitrectomia via pars plana. Nenhum dos 3 olhos (0%) implantados com dispositivo de drenagem de glaucoma anos antes da cirurgia de ceratoprótese apresentou complicações do segmento posterior, exceto progressão glaucomatosa. Dos 11 olhos sem história prévia de glaucoma, 3 (27,3%) apresentaram alta pressão intraocular e alterações do disco glaucomatoso após cirurgia de ceratoprótese, condições que podem ser controladas clinicamente. Conclusões: Nesta coorte, os olhos com glaucoma pré-existente foram mais difíceis de manejar, comparados àqueles que desenvolveram glaucoma após a cirurgia de ceratoprótese. Apareceram mais complicações retinianas quando o implante do dispositivo de drenagem de glaucoma foi realizado no máximo 6 meses antes da cirurgia de ceratoprótese do tipo afácico com vitrectomia parcial.

Observation of early clinical efficacy of unilateral biportal endoscopy technique in the treatment of lumbar postoperative adjacent segmental diseases / 中国骨伤

OBJECTIVE@#To investigate early clinical efficacy of unilateral biportal endoscopy technique for the treatment of lumbar postoperative adjacent segmental diseases.@*METHODS@#Fourteen patients with lumbar postoperative adjacent segmental diseases were treated with unilateral biportal endoscopy technique from June 2019 to June 2020. Among them, there were 9 males and 5 females, aged from 52 to 73 years old, and the interval between primary and revision operations ranged from 19 to 64 months. Adjacent segmental degeneration occurred after lumbar fusion in 10 patients and after lumbar nonfusion fixation in 4 patients. All the patients received unilateral biportal endoscopy assisted posterior unilateral lamina decompression or unilateral approach to the contralateral decompression. The operation time, postoperative hospital stay and complications were observed. The visual analogue scale (VAS) of low back pain and leg pain, Oswestry Disability Index (ODI), modified Japanese Orthopaedic Association (mJOA) score were recorded before operation and at 3 days, 3 months, and 6 months after operation.@*RESULTS@#All procedures were successfully completed. Surgical duration ranged from 32 to 151 min. Postoperative CT showed adequate decompression and preservation of most joints. Out of bed walking 1 to 3 days after surgery, postoperative hospital stay was 1 to 8 days, and postoperative follow-up was 6 to 11 months. All 14 patients returned to normal life within 3 weeks after surgery, and VAS, ODI, and mJOA scores improved significantly at 3 days and 3, 6 months after surgery. One patient occurred cerebrospinal fluid leak after operation, received local compression suture, and the wound healed after conservative treatment. One patient occurred postoperative cauda equina neurologic deficit, which was gradually recovered about 1 month after rehabilitation therapy. One patients advented transient pain of lower limbs after surgery, and the symptoms were relieved after 7 days of treatment with hormones, dehydration drugs and symptomatic management.@*CONCLUSION@#Unilateral biportal endoscopy technique has a good early clinical efficacy in the treatment of lumbar postoperative adjacent segmental diseases, which may provide a new minimally invasive, non-fixation option for the treatment of adjacent segment disease.

Global leadership initiative on malnutrition(GLIM)criteria in the diagnosis and treatment of malnutrition in patients with colorectal cancer / 肠外与肠内营养

Objective:This study aims to evaluate the incidence of postoperative malnutrition in colorectal cancer patients who underwent curative colorectal cancer surgery using the Golbal Leadership Initiative on Malnutrition(GLIM)criteria,and to explore the impact of malnutrition defined by the GLIM criteria on short-term clinical outcomes in patients with colorectal cancer.Method:We included a prospective cohort of 171 patients who underwent curative colorectal cancer surgery in Chongqing JiuLongpo People's Hospital from September 2022 to May 2023.Nutritional Risk Screening 2002(NRS 2002)was used for nutritional risk screening and GLIM criteria was used for the diagnosis of malnutrition.To compare the short-term postoperative clinical outcomes between the well-nourished group and the malnourished group under the GLIM criteria.Logistic regression analysis was conducted to analyze the risk factors of postoperative complications.Result:Among the included cases,nutritional screening data showed that 74(43.27％)patients were considered to be at risk of malnutrition(NRS 2002≥3),while based on GLIM criteria,63 patients(36.84％)were diagnosed as malnutrition.Univariate logistic regression analysis showed that GLIM-defined malnutrition was associated with total postoperative complications[odds ratio:2.075(95％CI:1.292～3.333),P=0.002].Multivariat analysis showed that women,BMI＜18.5kg/m2,smoking history,low differentiation of tumor,sarcopenia,laparotomy,low prealbumin,were independent risk factors for total postoperative complications.Conclusions:The nutritional diagnosis based on the GLIM criteria can effectively reflect the preoperative nutritional status of patients with colorectal cancer.GLIM-defined preoperative malnutrition can predict the risk of short-term complications in colorectal cancer patients who underwent curative colorectal cancersurgery.

Treatment of Pauwels Ⅲ femoral neck fractures with open reduction and fixation with cannulated screws and an augmented plate: a 3-year follow-up report / 中华创伤骨科杂志

Objective:To observe the curative effects and complications of open reduction and fixation with cannulated screws and an augmented plate for Pauwels type Ⅲ femoral neck fractures.Methods:A retrospective study was conducted to analyze the data of 8 patients with fresh Pauwels Ⅲ femoral neck fracture who had been treated from January 2015 to October 2018 at Department of Trauma and Orthopaedics, Xinjiang Uygur Autonomous Region Hospital of Traditional Chinese Medicine. There were 7 males and 1 female with an age of (47.7±14.0) years. The Pauwels angle ranged from 50° to 70° in 6 cases and was >70° in 2 cases. As the original closed reduction was not ideal in all the patients, open reduction via the modified Smith-Petersen approach and fixation with cannulated screws and an augmented plate were performed. Fracture healing, Harris hip score, and complications were followed up at 1 month, 6 months, 1 year, and 3 years postoperatively.Results:At 1 month after operation: 8 patients were followed up, their Harris hip score was (38.4±3.6) points, and there were 7 cases of femoral neck shortening and 1 case of incision fat liquefaction. At 6 months after operation: 7 patients were followed up, their Harris hip score was (70.6±2.8) points, and 1 patient healed anatomically, 4 patients healed with shortening, and 2 patients healed with delay and shortening. Femoral neck shortening, withdrawal of cannulated screws, and screw loosening within the augmented plate were all increased compared with 1 month after operation. At 1 year after operation: 7 patients were followed up, their Harris hip score was (85.5±4.4) points, there were no significant changes in fracture healing or complications compared with 6 months after operation. At 3 years after operation: the patient lost to prior follow-up died of heart disease 34 months after operation, 1 patient had to undergo total hip arthroplasty due to fracture nonunion and cutout of cannulated screws at 16 months after operation, and the other 6 patients had a Harris hip score of (93.6±2.5) points. Of the 6 patients, femoral neck fracture healed in 5 (shortening healing in 4, including 1 case complicated with femoral head necrosis, and anatomical healing in 1) but did not in one.Conclusions:In the treatment of Pauwels type Ⅲ femoral neck fractures, open reduction and fixation with cannulated screws and an augmented plate does not lead to ideal curative effects. The main complication is shortening of the femoral neck. The auxiliary role of augmented plate fixation is not obvious.

Accuracy of bedside lung ultrasound in predicting postoperative pulmonary complications in patients undergoing radical resection of gastrointestinal cancer / 中华麻醉学杂志

Objective:To evaluate the accuracy of bedside lung ultrasound in predicting postoperative pulmonary complications (PPCs) in the patients undergoing radical resection of gastrointestinal cancer.Methods:One hundred and eight patients of both sexes, aged >18 yr, undergoing elective radical resection of gastrointestinal cancer with general anesthesia, were enrolled in the study. Lung ultrasound was performed before surgery (T 1) and at 2, 4 and 7 days after surgery (T 2-4). Lung ultrasound score (LUS) and B-line score were recorded. Serum procalcitonin (PCT) concentrations and blood routine were recorded, and systemic immune-inflammatory index (SII) was calculated. All the patients underwent chest CT examination before surgery and 7 days after surgery. The results of chest CT and clinical diagnosis were used as the gold standard for PPCs. The occurrence of PPCs within 7 days after surgery was recorded. The patients were divided into PPCs group and non-PPCs group according to the development of PPCs. Spearman′s correlation analysis was used to analyze the correlation of B-line score and LUS with PPCs, PCT and SII. The receiver operating curve was used to evaluate the accuracy of B-line score and LUB in predicting PPCs. Results:One hundred and three patients were finally enrolled in the study, including 45 patients in PPCs group and 58 patients in non-PPCs group, and the incidence of PPCs was 43.7%. Both B-line score and LUS were positively correlated with PPCs at T 1 ( P<0.001), and B-line score and LUS were positively correlated with PCT and SII at T 2-4 ( P<0.001). The AUC (95% confidence interval) of B-line score and LUB in predicting PPCs were 0.926 (0.879-0.972) and 0.909 (0.852-0.965), respectively ( P<0.001), the best cut-off values of B-line score and LUB in predicting PPCs were set at 25.5 and 11.5 respectively, and the sensitivity and specificity of B-line score were 0.80 and 0.88 respectively, and the sensitivity and specificity of LUB were 0.78 and 0.93 respectively. Conclusions:Bedside pulmonary ultrasonography (B-line score and LUS) can accurately predict the occurrence of PPCs in the patients undergoing radical resection of gastrointestinal cancer and dynamically evaluate the condition of PPCs, and B-line score >25.5 and LUS score >11.5 indicate a high risk of PPCs.

Application of minimally invasive technique in kidney transplantation / 器官移植

Since the 21st century, minimally invasive technique has become a main development direction of surgery, which has been widely applied in all branches of surgery. In the field of kidney transplantation, minimally invasive technique has been mainly applied in the procurement of living donor kidney, kidney transplantation and the management of complications after kidney transplantation. It not only increases the resource of donor kidney, but also reduces the incidence of postoperative complications and enhances the quality of life of the recipients. The application of minimally invasive technique has become one of the research hot spots in the field of kidney transplantation. In this article, research progresses on the application of minimally invasive technique in the procurement of living donor kidney, kidney transplantation and management of complications after kidney transplantation were reviewed, aiming to provide reference for increasing the resource of donor kidney, enhancing the success rate of kidney transplantation and improving clinical prognosis of kidney transplant recipients, thereby promoting the development of minimally invasive technique in surgery.

Prospective study on the effect of prophylactic octreotide administration in preventing pancreatic fistula after pancreatoduodenectomy / 中华胰腺病杂志

Objective:To evaluate the effect of prophylactic octreotide administration on pancreaticoduodenectomy (PD)associated postoperative pancreatic fistula (POPF), total complications, peri-operative death and postoperative in-hospital days.Methods:From January 2020 to August 2021, 148 patients who underwent PD in the Department of Biliary-Pancreatic Surgery in Ren Ji Hospital affiliated with School of Medicine of Shanghai Jiao Tong University were recruited into this single-center randomized control double-blinded clinical trial. Patients were randomly assigned into octreotide group ( n=74) and control group ( n=74). Octreotide group was subcutaneously injected with 0.1 mg (1 ml) octreotide after preoperative anesthesia, and was subcutaneously injected with the same dose every 8 hours for 5 days, with a total of 16 doses. Control group was injected with 1 ml normal saline in the same way, and relevant clinical data and indicators of the two groups were recorded. The primary endpoint was clinically relevant pancreatic fistula, and the secondary endpoints were total complications, perioperative death and postoperative in-hospital days. Univariate and multivariate logistic regression analysis were used to screen the risk factors of clinically related POPF after PD. Results:120 patients were finally enrolled, including 61 in octreotide group and 59 in control group. There were no significant differences on age, gender ratio, body mass index, preoperative surgery rate of jaundice reduction, preoperative major biochemical indicators, operation time, intraoperative blood loss, pancreatic duct diameter, pancreatic texture and pathological type composition ratio. The total incidence of clinical relevant POPF was 8.3%, and there were no significant differences on biochemical leakage (4.9% vs 8.5%, P=0.435), grade B fistula (4.9% vs 8.5%, P=0.435) and grade C fistula (1.6% vs 1.7%, P=0.981). The total complication incidence (24.5% vs 28.8%, P=0.601), perioperative mortality (0 vs 3.3%, P=0.147) and postoperative in-hospital days (20.6±11.1 d vs 19.5±12.2 d, P=0.633) were not significantly different between two groups. Univariate analysis showed that preoperative serum albumin level <30 g/L( P<0.001) and pathological type of pancreatic ductal adenocarcinoma ( P=0.036) were independent risk factors for POPF after PD, while multivariate analysis found no statistically significant risk factors. Conclusions:Octreotide can neither reduce the incidences of POPF, total complications and postoperative mortality, nor shorten postoperative in-hospital days. However, for patients with preoperative hypoproteinemia and (or) the pathological type of pancreatic duct adenocarcinoma, the prophylactic use of octreotide during PD and after PD may reduce the occurrence of POPF.

Study on the relationship between intraoperative pain and postoperative complications in mid-aged and elderly osteoporotic vertebral fracture patients treated with vertebroplasty / 中华老年医学杂志

Objective:To examine the correlation between intraoperative pain scores during puncturing and postoperative complications in elderly patients with osteoporotic vertebral fractures(OVF)treated with vertebroplasty(VP).Methods:In a retrospective case-control study, clinical data of 326 patients with single-segment OVF treated with VP, including 42 patients(12.9%)(the complication group)with complications within 1 month of surgery and 284 patients(87.1%)without complications(the control group), were compared.Changes in patient numerical evaluation scale(NRS)scores were recorded and compared for the complication group and the control group at different time points, which concluded preoperative(T0), intraoperative puncturing of soft tissues(T1), bone puncturing(T2), bone cement injection into the vertebral body(T3), 24 hours(T4), 1 month(T5)and 3 months(T6)after surgery.Results:NRS scores for patients in the complication group vs.those in the control group at different phase were(5.78±2.11 vs.6.10±2.21)points at T0, (7.59±1.46 vs.4.63±0.86)points at T1, (7.30±1.35 vs.5.14±1.07)points at T2, (6.97±1.24 vs.6.11±1.58)points at T3, (4.09±0.82 vs.2.19±0.87)points at T4, (2.07±0.80 vs.1.93±0.78)points at T5, and(1.83±0.72 vs.1.74±0.65)points at T6, but there was no significant difference between the two groups at T0( P>0.05).The complication group had higher NRS scores than the control group at T1, T2, T3, and T4(all P<0.05).For intra-group comparisons, both the complication group and the control group showed statistically significant differences between T0 and T4, between T0 and T5, and between T4 and T5(all P<0.05). Conclusions:Elderly OVF patients who are treated with VP and exhibit post-surgery complications often experienced severe pain during surgery, and an NRS score greater than 7 may be an independent risk factor for postoperative complications of VP.Effort should be made to avoid or reduce complications related to surgery, reduce pain and improve treatment outcomes of VP for elderly patients.

Recomendaciones para el manejo clínico del niño en el posoperatorio de adenoamigdalectomía / Recommendations for the clinical management of the child in the postoperative adenoamygdalectomy

El síndrome de apneas e hipoapneas obstructivas del sueño se asocia con una disminución de la calidad de vida, bajo rendimiento escolar y, hasta en el 40% de los niños, trastornos de conducta como hiperactividad, enuresis, ansiedad y depresión. Varios estudios demostraron que la adenoamigdalectomía es efectiva para mejorar o resolver los trastornos respiratorios del sueño. Si bien esta cirugía tiene resultados beneficiosos, no está exenta de riesgos. El dolor y el sangrado posoperatorio son las dos causas principales de morbilidad. Otras complicaciones de la cirugía son las náuseas y los vómitos posoperatorios, el retraso en la alimentación, la deshidratación, la otalgia referida, los cambios en la voz y, raras veces, la muerte.En este artículo se realizan recomendaciones sobre el cuidado posoperatorio de los niños con adenoamigdalectomía

Obstructive sleep apnea and hypopnea syndrome is associated with decreased quality of life, poor school performance and, in up to 40% of children, behavioral problems such as hyperactivity, enuresis, anxiety and depression. Several studies have shown that adenoamygdalectomy is effective in improving or resolving sleep-disordered breathing. While this surgery has beneficial results, it is not without risks. Postoperative pain and bleeding are the two main causes of morbidity. Other complications of surgery include postoperative nausea and vomiting, delayed feeding, dehydration, referred earache, voice changes, and, rarely, death. Recommendations on postoperative care for children undergoing adenoamygdalectomy are mentioned in this article.

Resultados asociados con la realización de colecistectomía subtotal en un hospital de tercer nivel de Bogotá / Results of partial cholecystectomy in a tertiary level hospital in Bogotá

Resumen Introducción: La colecistectomía laparoscópica es actualmente el gold standard en patología vesicular litiásica. Hay un grupo de pacientes que tiene un gran proceso inflamatorio que impide la identificación adecuada del triángulo de seguridad. Dado lo anterior, una alternativa es la realización de colecistectomía subtotal por laparoscopia, para reducir el riesgo de lesión de vía biliar. Objetivo: Describir los resultados clínicos y quirúrgicos en pacientes que se sometieron a la realización de colecistectomía subtotal laparoscópica en el Hospital Universitario Clínica San Rafael en el periodo comprendido entre febrero de 2015 y febrero de 2017. Materiales y Método: Serie de casos, donde se realizó un análisis descriptivo para determinar la distribución de las variables, se utilizaron tablas de contingencia, pruebas Fischer según el caso y su distribución en número y normalidad. Resultados: Se obtuvo información de 28 pacientes, con un promedio de edad de 56,1 años, mayor proporción de hombres. En cuanto a las características clínicas se observaron los antecedentes de diabetes e hipertensión arterial. No hubo complicaciones ni sangrado intraoperatorio importantes. En resultados posoperatorios no se presentó lesión de vía biliar en ninguno, hubo 3 reingresos (10,7%) y hubo una reintervención relacionada con colección intraabdominal. Se reportó una mortalidad secundaria a neumonía. Conclusión: La colecistectomía subtotal es un procedimiento seguro en cuanto a la prevención de lesión de vía biliar.

Introduction: Laparoscopic cholecystectomy is actually the gold standard surgical approach to the gallbladder disease. Some patients with severe cholecystitis and inflammatory changes that makes impossible to dissect the hepatocystic triangle. Is in this case, where the laparoscopic subtotal cholecystectomy is an option, to reduce the risk of biliary injury. Aim: To describe the clinical and surgical results in patients that underwent in laparoscopic subtotal cholecystectomy at Hospital Universitario Clínica San Rafael since February 2015 to February 2017. Materials and Method: A case series study was carried out, with a descriptive analysis to determine the distribution of them. We used contingency tables and fischer tests. Results: 28 laparoscopic subtotal cholecystectomy. The average age of 56.1 years, fifty percent was men. At the clinical characteristics, the history of diabetes and arterial hypertension was observed. There was no bile duct lesion in any and there was a reintervention due to intra-abdominal collection and only one mortality. 50% had biliary leakage and 25% of cases required endoscopic intervention. Conclusion: Laparoscopic subtotal cholecystectomy is a safe procedure.

Impacto do envelhecimento nos resultados cirúrgicos dos pacientes com câncer gástrico / Impact of aging in the surgical outcomes of gastric cancer patients

ABSTRACT BACKGROUND: As age advances, a higher burden of comorbidities and less functional reserve are expected, however, the impact of aging in the surgical outcomes of gastric cancer (GC) patients is unknown. OBJECTIVE: The aim of this study is to evaluate surgical outcomes of GC patients according to their age group. METHODS: Patients submitted to gastrectomy with curative intent due to gastric adenocarcinoma were divided in quartiles. Each group had 150 patients and age limits were: ≤54.8, 54.9-63.7, 63.8-72, >72. The outcomes assessed were: postoperative complications (POC), 90-day postoperative mortality, disease-free survival (DFS) and overall survival (OS). RESULTS: Major surgical complications were 2.7% in the younger quartile vs 12% for the others (P=0.007). Major clinical complications raised according to the age quartile: 0.7% vs 4.7% vs 5.3% vs 7.3% (P<0.042). ASA score and age were independent risk factors for major POC. The 90-day mortality progressively increased according to the age quartile: 1.3% vs 6.0% vs 7.3% vs 14% (P<0.001). DFS was equivalent among quartile groups, while OS was significantly worse for those >72-year-old. D2 lymphadenectomy only improved OS in the three younger quartiles. Age >72 was an independent risk factor for worse OS (hazard ratio of 1.72). CONCLUSION: Patients <55-year-old have less surgical complications. As age progresses, clinical complications and 90-day mortality gradually rise. OS is worse for those above age 72, and D2 lymphadenectomy should be individualized after this age.

RESUMO CONTEXTO: Conforme a idade avança, se esperam mais morbidades e menor reserva funcional. Entretanto não está claro qual o impacto do envelhecimento nos resultados cirúrgicos do câncer gástrico (CaG). OBJETIVO: O intuito deste estudo é avaliar os resultados cirúrgicos de pacientes com CaG de acordo com o grupo etário. MÉTODOS: Pacientes submetidos a gastrectomia por adenocarcinoma gástrico com intuito curativo foram divididos em quartis. Cada grupo incluiu 150 indivíduos e os limites etários foram: ≤54,8; 54,9-63,7; 63,8-72; >72. Os resultados avaliados foram: complicações pós-operatórias (CPO), mortalidade em 90 dias, sobrevida livre de doença (SLD) e sobrevida global (SG). RESULTADOS: Complicações cirúrgicas maiores ocorreram em 2,7% dos pacientes no quartil mais jovem vs 12% para os demais (P=0,007). A incidência de complicações clínicas maiores aumentou conforme o quartil: 0,7% vs 4,7% vs 5,3% vs 7,3% (P<0,042). A pontuação ASA e a idade foram fatores de risco independentes para CPO maiores. A mortalidade em 90 dias aumentou progressivamente conforme o quartil etário: 1,3% vs 6,0% vs 7,3% vs 14% (P<0,001). A SLD foi equivalente entre os quartis, enquanto a SG foi significativamente pior para os >72 anos de idade. Linfadenectomia D2 aumentou a SG apenas para os 3 quartis mais jovens. Idade > 72 foi fator independente de risco para pior SG (razão de chances de 1,72) CONCLUSÃO: Pacientes < 55 anos tem menos complicações cirúrgicas. Conforme a idade avança, as complicações clínicas e a mortalidade em 90 dias aumenta gradualmente. A SG é pior se >72 anos e a indicação de linfadenectomia D2 deve ser individualizada a partir dessa idade.
