Introdução: A saúde bucal é um aspecto que não deve ser subestimado pelos pacientes, principalmente se considerar que as infecções odontogênicas podem levar a quadros graves, incluindo complicações cervicotorácicas, como Mediastinite e cervicofaciais, como Angina de Ludwig. Para tanto, é imprescindível que os profissionais da odontologia saibam reconhecer os principais sinais e sintomas dessas infecções, sua evolução, conhecer as complicações associadas e qual o manejo adequado. Objetivo: Assim, é objetivo deste trabalho, relatar, discutir um caso clínico de uma infecção odontogênica grave que acarretou em complicação cervical, com trajeto em direção ao mediastino, necessitando manejo multidisciplinar, e explorar os principais aspectos desse quadro e a conduta necessária, que exige, no mínimo, intervenção cirúrgica, antibioticoterapia e manutenção das vias aéreas. Relato de caso: O caso trata de um paciente com infecção odontogênica, iniciada como uma pericoronarite do dente 38 semieruptado, que evoluiu para a área cervical, demandando imediata drenagem nesta região pois encaminhava-se para uma mediastinite. Após a drenagem cervical e antibioticoterapia e, assim que houve redução do trismo, foi removido o dente 38, evoluindo para a cura.Conclusões:As infecções odontogênicas, principalmente as que acometem os espaços fasciais e cervicais profundos, são potencialmente graves e devem ter suas principais manifestações clínicas entre os domínios de conhecimento dos profissionais Bucomaxilofaciais, pois necessitam de diagnóstico preciso, manejo rápido e tratamento adequado e precoce, considerando a velocidade com que podem evoluir (AU).

Introduction: Oral healthis an aspect that should not be underestimated by patients, especially considering that dental infections can lead to serious symptoms, including cervicothoracic complications, such as Mediastinitis and cervicofacial complications, such as Ludwig's Angina. Therefore, it is essential that dental professionals know how to recognize the main signs and symptoms of these infections, their evolution, know the associated complications and appropriate management.Objective: Thus, this work aims to report and discuss a clinical case of a serious odontogenic infection that resulted in a cervical complication, with a path towards the mediastinum, requiring multidisciplinary management, and to explore the main aspects of this condition and the necessary conduct, which requires, at least, surgical intervention, antibiotic therapy and airway maintenance.Case report: The case concerns a patient with odontogenic infection, which began as pericoronitis of semi-erupted tooth 38, which progressed to the cervical area, requiring immediate drainage in this region as it was heading towards mediastinitis. After cervical drainage and antibiotic therapy and, as soon as the trismus was reduced, tooth 38 was removed, progressing towards healing.Conclusions: Odontogenic infections, especially those that affect the fascial and deep cervical spaces, are potentially serious and should have their main clinical manifestations among the domains of knowledge ofOral and Maxillofacial professionals, as they require accurate diagnosis, rapid management and adequate and early treatment, considering the speed at which they can evolve (AU).

Escisión de Glándula Submandibular por Sialoadenitis Crónica Esclerosante Asociada a Sialolito en el Conducto Submandibular / Submandibular Gland Excision Due to Chronic Sclerosing Sialadenitis Associated With Sialolith in Submandibular Duct

La sialoadenitis crónica esclerosante puede extenderse desde una sialoadenitis focal hasta una cirrosis completa de la glándula. Aparece entre los 40 y 70 años de edad y afecta principalmente a la glándula submandibular. Se asocia con sialolitos y agentes infecciosos inespecíficos. La causa más frecuente de sialolitiasis es la formación de cálculos macroscópicamente visibles en una glándula salival o en su conducto excretor, de los cuales el 80 % al 90 % provienen de la glándula submandibular. Esta predilección probablemente se deba a que su conducto excretor es más largo, más ancho y tiene un ángulo casi vertical contra la gravedad, contribuyendo así a la estasis salival. Además, la secreción semimucosa de la misma es más viscosa. El sitio principal de ubicación de los litos en el conducto submandibular es la región hiliar con un 57 %. La sintomatología típica de la sialolitiasis es el cólico con tumefacción de la glándula y los dolores posprandiales. Reportamos el caso de un paciente masculino de 55 años, quien ingresa al servicio de Cirugía Oral y Maxilofacial del Hospital General Balbuena de la Ciudad de México por presentar un aumento de volumen en la región submandibular izquierda de consistencia dura y dolorosa a la palpación de 15 días de evolución, acompañada de aumento de temperatura en la zona compatible con un absceso. Los estudios de imagen reportan un sialolito en la región hiliar del conducto submandibular de 2,0 x 1,7 x 1,0 cm. Debido a su localización y tamaño, el tratamiento ideal en estos casos es la escisión de la glándula junto con el lito previo drenaje del absceso e inicio de terapia antibiótica doble.

Chronic sclerosing sialadenitis can range from focal sialadenitis to complete cirrhosis of the gland. It appears between 40 and 70 years of age and mainly affects the submandibular gland. It is associated with sialoliths and nonspecific infectious agents. The most common cause of sialolithiasis is the formation of macroscopically visible stones in a salivary gland or its excretory duct, of which 80 % to 90 % come from the submandibular gland. This predilection isprobably due to the fact that their excretory duct is longer, wider and has an almost vertical angle against gravity, thus contributing to salivary stasis. In addition, the semimucous secretion of it is more viscous. The main location of the stones in the submandibular duct is the hilar region with 57 %. The typical symptomatology of sialolithiasis is colic with swelling of the gland and postprandial pain. We report the case of a 55-year-old male patient, who was admitted to the Oral and Maxillofacial Surgery Service of the Hospital General Balbuena in Mexico City due to an increase in volumen in the left submandibular region that was hard and painful on palpation of 15 days of evolution, accompanied by increased temperature in the area compatible with an abscess. Imaging studies report a 2.0 x 1.7 x 1.0 cm sialolith in the submandibular duct hilar region. Due to its location and size, the ideal treatment in these cases is excision of the gland together with the stone previous drainage of the abscess and initiation of dual antibiotic therapy.

Fístula sigmoido-glútea como complicación infrecuente de la enfermedad diverticular / Sigmoid-gluteal fistula as a rare complication of diverticular disease

Las fistulas colo-cutáneas de origen diverticular son poco frecuentes, máxime en ausencia de cirugía o drenaje percutáneo previos. Presentamos una mujer de 90 años con una sigmoitis complicada con una colección abdominal perforada hacia el retroperitoneo y la región glútea. (AU)

Colocutaneous fistulas of diverticular origin are rare, especially in the absence of prior surgery or percutaneous drainage. We report the case of a 90-year-old woman with sigmoitis and a perforated abdominal collection in the retroperitoneum and gluteal region. (AU)

Mama supranumeraria: resección mediante técnica abierta con dren versus sin dren / Supranumerary breast: resection by open technique with drain vs without drain

Introducción. El tejido mamario accesorio es una anomalía congénita que se presenta en el 2-6 % de la población femenina. En este tejido se pueden desarrollar las mismas patologías que en la mama normal. El manejo curativo es la resección quirúrgica. El objetivo de este estudio fue comparar los resultados de la técnica de resección vía abierta de tejido mamario accesorio con dren vs sin dren. Métodos. Se realizó un estudio observacional tipo cohorte retrospectivo, teniendo en cuenta dos grupos de pacientes con tejido mamario accesorio: a uno de ellos se les realizó resección quirúrgica mediante técnica abierta con dren y al otro grupo sin dren. Además, se incluyó un brazo prospectivo donde se evaluó la calidad de vida y la satisfacción de las pacientes con el resultado posoperatorio mediante el uso de la herramienta Breast-Q. Resultados. Se recolectó la información de 82 pacientes, la mayoría mujeres; 22 se intervinieron con técnica con dren y 60 con técnica sin dren. 13,6 % de los pacientes presentaron complicaciones tempranas, siendo la infección de sitio operatorio la más frecuente (36,4 %). En general, las complicaciones fueron más comunes en el grupo con dren (40,9 % vs 3,4 %), con una diferencia estadísticamente significativa (p=0,000). La calidad de vida fue similar en ambos grupos. Conclusiones. Los pacientes a quienes se les realizó resección de mama supernumeraria y se dejó un sistema de drenaje en el lecho de disección presentaron más complicaciones posoperatorias que las pacientes a quienes no se les dejó dren

Introduction. Accessory breast tissue is a congenital anomaly that occurs in 2-6% of the female population. It can develop the same pathologies that in the normal breast. The curative management of this pathology is surgical resection. The objective of this study was to compare the results of the accessory breast tissue open resection technique with a drain vs without a drain. Methods. An observational retrospective cohort study was conducted considering two groups of patients with accessory breast tissue: one of them underwent surgical resection using an open technique with a drain and the other group without a drain. In addition, a prospective arm where the quality of life and satisfaction of the patients with the postoperative result was evaluated by the Breast-Q tool. Results. Eighty-two patients were included, most of them women; 22 were operated with open technique with drain and 60 without drain. 13.6% of patients presented early complications, with surgical site infection being the most frequent (36.4%) and, in general, complications were more common in the group with drain (40.9% vs 3.4%) with a statistically significant difference (p=0.000). Quality of life was similar in both groups.Conclusions. Patients who undergo supernumerary breast resection and leaving drainage in the dissection bed present more postoperative complications compared to those without drain

Advances in surgical treatment of hidradenitis suppurative / 浙江大学学报·医学版

Hidradenitis suppurative is a chronic, refractory and recurrent dermatological disease. The disease should be managed by targeted surgical intervention on the basis of medical treatment. Currently, the surgical treatment methods include local treatments like incision and drainage, unroofing, laser therapy, intense pulsed light therapy, photodynamic therapy, as well as complete lesion resection such as skin-tissue saving excision with electrosurgical peeling and extended excision. The clearance range, therapeutic effect, postoperative complications, and recurrence risk vary among the different treatment methods. Local treatments cause less damage, but have high recurrence rates, and are mainly for mild to moderate hidradenitis suppurative patients. Complete lesion resections have relatively low recurrence rates, but may bring more surgical injuries, and postoperative reconstructions are needed, which are mainly for moderate to severe hidradenitis suppurative patients. In this article, the surgical treatment principles and various surgical treatment methods of hidradenitis suppurative are reviewed, to provide a reference for the diagnosis and treatment of this disease in clinical practice.

Comparison of therapeutic effects of arthroscopic popliteal cyst internal drainage and capsular wall resection / 中国骨伤

OBJECTIVE@#To investigate efficacy between arthroscopic popliteal cyst drainage and arthroscopic popliteal cyst resection.@*METHODS@#From January 2013 to June 2021, 54 patients with popliteal cyst (Rausching-Lindgren gradeⅠto Ⅲ) were treated with arthroscopic surgery. There were 24 males and 30 females. The age ranged from 44 to 72 years old, with a mean of (62.67±6.08) years old. The course of the disease ranged from 1 to 72 months, with a mean of(15±14) months. Twenty-four patients (group A) were underwent arthroscopic internal drainage of popliteal cyst. Thirty patients (group B) were underwent arthroscopic resection of popliteal cyst. Preoperative main symptoms included knee pain, swelling, walking pain, popliteal swelling, popliteal mass and so on. After 1, 3, 6 months and 1, 2 years of surgery, routine outpatient follow-up was conducted to observe and compare the surgical time, bleeding volume, preoperative and postoperative visual analog scale (VAS), knee Lysholm score, and complications between two groups.@*RESULTS@#All incisions healed at one stage after operation. All 54 patients were followed up, and the duration ranged from 6 months to 2 years, with an average of (13.89±4.29) months. There was no intraoperative vascular or nerve injury. Operation time and intraoperative blood loss of the two groups:group A of (62.08±9.55) min and (8.00±1.69) ml, group B of (69.50±6.99) min and (8.70±2.00) ml. Popliteal pain, swelling, limitation of flexion and extension were significantly relieved after operation. VAS before and one month after operation between two groups:group A of 5.38±1.21 and 2.63±0.71, group B of 5.60±1.26 and 2.80±0.81. Lysholm scores of knee joint before and 6 months after operation:group A of 62.59±4.99 and 89.74±2.90, group B of 63.87±3.23 and 89.02±2.35. Knee joint function improved significantly in both groups. In group A, 4 cases had popliteal cyst at 3 months after operation, and 2 cases had small isolated cyst at 1 year after operation. There was no recurrence of cyst in group B.@*CONCLUSION@#The results between two arthroscopic treatments of popliteal cyst are satisfactory, and there is no significant difference in the amount of blood loss, safety, postoperative pain VAS score and knee function recovery. It is suggested that arthroscopic resection of the cyst wall should be performed when the technique is mature, especially for large cysts and septal cysts.

The common morphology and clinical significance of the axillary arch / 中华外科杂志

Axillary arch is the most common type of axillary muscle fiber variation, with about 10.8% incidence in the Chinese population. Its natural forms are varied and fluid, with different starting points and terminations, and clinicians frequently lack recognition. Under commonly applicated sentinel lymph node biopsy, the axillary arch has been endowed with more clinical significance. The fabric of axillary arch will not only block lymphatic drainage in axilla and unclear anatomical level of axillary dissection, but also compress the axillary neurovascular bundle, causing upper limb venous thrombosis, lymphedema and nerve entrapment. The intumescent axillary arch may also show abnormal axillary bulge. In addition to finding axillary arch during cadaveric study and operation, several of imaging methods availably diagnose axillary arch preoperative, which can create new way for detection of axillary arch and extension of the surgical plan of sentinel lymph node biopsy. Although embryology and comparative anatomy have been used to explain the origin of the axillary arch, most of the ideas are still hypotheses and need further study.

Evaluation of uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculous empyema / 中华外科杂志

Objective: To examine the safety and efficacy of the uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculosis empyema. Methods: From January 2018 to December 2020, 122 cases of tuberculous empyema treated by decortication in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed, including 100 males and 22 females, aged(M(IQR)) 29.5(28.0) years (range: 13 to 70 years). According to the surgical approach and drug resistance, patients with drug-resistant tuberculosis who underwent uniportal video-assisted thoracoscopic decortication were included in group A (n=22), and those who underwent thoracotomy decortication were included in group B (n=28). Drug-sensitive patients who underwent uniportal video-assisted thoracoscopic decortication were included in group C (n=72). There was no statistical difference in the baseline data of the three groups (P>0.05). The operation, early postoperative recovery, and prognosis-related indicators were compared among three groups by Kruskal-Wallis test and χ2 test by Mann-Whitney U test and Bonferroni method between groups A and B, groups A and C. Results: The intraoperative blood loss of group A, group B, and group C was 200(475) ml, 300(200) ml, and 225(300) ml, respectively. There was no significant difference in intraoperative hemorrhage (H=2.74, P=0.254) and treatment outcome (χ2=4.76, P=0.575) among the three groups. Compared with group B, the operation time of group A (302.5(187.5) minutes vs. 200.0(60.0) minutes, U=171.0, P=0.007) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0 (2.2) months, U=146.5, P=0.032) were longer, and the postoperative drainage duration (9.5(7.8) days vs. 13.0(10.0) days, U=410.0, P=0.044), and the postoperative hospitalization time (12.0(7.8) days vs. 14.5(4.8) days, U=462.2, P=0.020) were shorter. There was no significant difference in complications between group A and group B (63.6%(14/22) vs. 71.4%(20/28), χ2=0.34, P=0.558). Compared with group C, the postoperative drainage duration of group A (9.5(7.8) days vs. 7.0(4.0) days, U=543.5, P=0.031), the postoperative hospitalization time (12.0(7.8) days vs. 9.0(4.0) days, U=533.0, P=0.031) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0(2.0) months, U=961.5, P=0.001) were longer. The operation time (302.5(187.5) minutes vs. 242.5(188.8) minutes, U=670.5, P=0.278), and complications (63.6%(14/22) vs. 40.3%(29/72), χ2=3.70, P=0.054) were not different between group A and group C. Conclusions: For drug-resistant tuberculous empyema, the uniportal video-assisted thoracoscopic decortication can achieve the same good therapeutic effect as drug-sensitive tuberculous empyema, and it is as safe as thoracotomy. At the same time, it has the advantage of minimally invasive and can accelerate the early postoperative recovery of patients.

Basic principles,methods and evaluation of minimally invasive treatment for infected pancreatic necrosis / 中华外科杂志

Infected pancreatic necrosis(IPN) is the main surgical indication of acute pancreatitis. Minimally invasive debridement has become the mainstream surgical strategy of IPN,and it is only preserved for IPN patients who are not response for adequate non-surgical treatment. Transluminal or retroperitoneal drainage is preferred,and appropriate debridement can be performed. At present,it is reported that video assisted transluminal,trans-abdominal and retroperitoneal approaches can effectively control IPN infection. However,in terms of reducing pancreatic leakage and other complications,surgical and endoscopic transgastric debridement may be the future direction in the treatment of IPN.

Analysis of the causes of long-standing pelvic anterior sacral space infection and discussion of management techniques / 中华肿瘤杂志

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

The timing of pericardial drainage catheter removal and restart of the anticoagulation in patients suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran: Experiences from 20 cases / 中华心血管病杂志

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

Application of modified alternate negative pressure drainage instrument after posterior lumbar fusion / 中国骨伤

OBJECTIVE@#To investigate the effect of modified alternate negative pressure drainage on postoperative outcomes after posterior lumbar interbody fusion (PLIF) surgery.@*METHODS@#This was a prospective study involving 84 patients who underwent PLIF surgery between January 2019 and June 2020. Of these patients, 22 had single-segment surgery and 62 had two-segment surgery. Patients were grouped by surgical segment and admission sequence:the observation group included patients with a single-segment surgery, and the control group included patients with a two-segment surgery. Natural pressure drainage was given to 42 patients in the observation group (modified alternate negative pressure drainage group) after surgery, which was then changed to negative pressure drainage after 24 hours. In the control group, 42 patients were given negative pressure drainage after surgery, which was then changed to natural pressure drainage after 24 hours. The total drainage volume, drainage time, maximum body temperature at 24 hours and 1 week after surgery, and drainage-related complications were observed and compared between the two groups.@*RESULTS@#There was no significant difference in operative time and intraoperative blood loss between the two groups. The postoperative total drainage volume was significantly lower in the observation group (456.69±124.50) ml than in control group (572.36±117.75) ml, and the drainage time was significantly shorter in the observation group (4.95±1.31) days than in the control group (4.00±1.17) days. Maximum body temperature at 24 hours after surgery was similar in both groups (37.09±0.31)°C in the observation group and (37.03±0.33)°C in the control group, while on the 1st week after surgery, it was slightly higher in the observation group (37.05±0.32)°C than in the control group (36.94±0.33)°C, but the difference was not significant. There were no significant differences in drainage-related complications, with one case(2.38%) of superficial wound infection in the observation group and two cases(4.76%) in control group.@*CONCLUSION@#Modified alternate negative pressure drainage after posterior lumbar fusion can reduce the drainage volume and shorten the drainage time without increasing the risk of drainage-related complications.

Feasibility and safety of one-stage bilateral video-assisted thoracic surgery for resection of bilateral multiple pulmonary nodules / 南方医科大学学报

OBJECTIVE@#To evaluate the feasibility and safety of one- stage bilateral video-assisted thoracic surgery (VATS) for resection of bilateral multiple pulmonary nodules (BMPNs).@*METHODS@#We analyzed the clinical characteristics, pathological features, perioperative outcomes and follow-up data of 41 patients with BMPNs undergoing one-stage bilateral VATS from July, 2011 to August, 2021.@*RESULTS@#One-stage bilateral VATS was performed uneventfully in 40 of the patients, and conversion to open surgery occurred in 1 case. The surgical approaches included bilateral lobectomy (4.9%), lobar-sublobar resection (36.6%) and sublobar-sublobar resection (58.5%) with a mean operative time of 196.3±54.5 min, a mean blood loss of 224.6±139.5 mL, a mean thoracic drainage duration of 4.7±1.1 days and a mean hospital stay of 14±3.8 days. Pathological examination revealed bilateral primary lung cancer in 15 cases, unilateral primary lung cancer in 21 cases and bilateral benign lesions in 5 cases. A total of 112 pulmonary nodules were resected, including 67 malignant and 45 benign lesions. Postoperative complications included pulmonary infection (5 cases), respiratory failure (2 cases), asthma attack (2 cases), atrial fibrillation (2 cases), and drug-induced liver injury (1 case). No perioperative death occurred in these patients, who had a 1-year survival rate of 97.6%.@*CONCLUSION@#With appropriate preoperative screening and perioperative management, one-stage bilateral VATS is feasible and safe for resection of BMPNs.

Clinical management and prognosis for descending necrotizing mediastinitis / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the clinical characteristics, treatment experiences and prognostic factors for descending necrotizing mediastinitis (DNM). Methods: A retrospective analysis was performed on the data of 22 patients with DNM diagnosed and treated in Henan Provincial People's Hospital from January 2016 to August 2022, including 16 males and 6 females, aged 29-79 years. After admission, all patients underwent CT scanning of the maxillofacial, cervical, and thoracic regions to confirm their diagnoses. Emergency incision and drainage were performed. The neck incision was treated with continuous vacuum sealing drainage. According to the prognoses, the patients were divided into cure group and death group, and the prognostic factors were analyzed. SPSS 25.0 software was used to analyze the clinical data. Rusults: The main complaints were dysphagia (45.5%, 10/22) and dyspnea (50.0%, 11/22). Odontogenic infection accounted for 45.5% (10/22) and oropharyngeal infection accounted for 54.5% (12/22). There were 16 cases in the cured group and 6 cases in the death group, with a total mortality rate of 27.3%. The mortality rates of DNM typeⅠand typeⅡwere respectively 16.7% and 40%. Compared with the cured group, the death group had higher incidences for diabetes, coronary heart disease and septic shock (all P<0.05). There were statistically significant differences between the cure group and the death group in procalcitonin level (50.43 (137.64) ng/ml vs 2.92 (6.33) ng/ml, M(IQR), Z=3.023, P<0.05) and acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score (16.10±2.40 vs 6.75±3.19, t=6.524, P<0.05). Conclution: DNM is rare, with high mortality, high incidence of septic shock, and the increased procalcitonin level and APACHE Ⅱ score combined diabetes and coronary heart disease are the poor prognostic factors for DNM. Early incision and drainage combined with continuous vacuum sealing drainage technique is a better way to treat DNM.

Methods: We conducted a systematic search for relevant studies published from inception to October 2022 across multiple databases, including PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP. Meta-analysis was performed using Review Manager 5.4 software. The primary outcomes included total incidence of anastomotic leak, grade B and C anastomotic leak rates, reoperation rate, anastomotic bleeding rate, and overall complication rate. Results: Three randomized controlled trials involving 1115 patients (559 patients in the TDT group and 556 in the non-TDT group) were included. Meta-analysis showed that the total incidences of anastomotic leak and of grade B anastomotic leak were 5.5% (31/559) and 4.5% (25/559), respectively, in the TDT group and 7.9% (44/556) and 3.8% (21/556), respectively, in the non-TDT group. These differences are not statistically significant (P=0.120, P=0.560, respectively). Compared with the non-TDT group, the TDT group had a lower incidence of grade C anastomotic leak (1.6% [7/559] vs. 4.5% [25/556]) and reoperation rate (0.9% [5/559] vs. 4.3% [24/556]), but a higher incidence of anastomotic bleeding (8.2% [23/279] vs. 3.6% [10/276]). These differences were statistically significant (P=0.003, P=0.001, P=0.030, respectively). The overall complication rate was 26.5%(74/279) in the TDT group and 27.2% (75/276) in the non-TDT group. These differences are not statistically significant (P=0.860). Conclusions: TDT did not significantly reduce the total incidence of anastomotic leak but may have potential clinical benefits in preventing grade C anastomotic leak. Notably, placement of TDT may increase the anastomotic bleeding rate.

Evolution and progress of surgical intervention strategies for acute pancreatitis / 中华外科杂志

Acute pancreatitis is one of the common surgical acute abdominal diseases. Since people first recognized acute pancreatitis in the middle of the nineteenth century, a diversified minimally invasive treatment model with standardization has been formed today. According to the main line of surgical intervention of acute pancreatitis treatment,this period can be roughly divided into five stages:exploration stage, conservative treatment stage, pancreatectomy stage, debridement and drainage of the pancreatic necrotic tissue stage, and minimally invasive treatment as the first choice led by the multidisciplinary team mode stage. Throughout history, the evolution and progress of surgical intervention strategies for acute pancreatitis cannot be separated from the progress of science and technology, the update of treatment concepts and the further understanding of the pathogenesis. This article will summarize the surgical characteristics of acute pancreatitis treatment at each stage to explain the development of surgical treatment of acute pancreatitis,to help investigate the development of surgical treatment of acute pancreatitis in the future.

Diagnosis and treatment of 18 cases of Chiari malformation with hoarseness / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the diagnosis and treatment of Chiari malformation patients with hoarseness and other otorhinolaryngological symptoms. Methods: The clinical data of 18 patients of Chiari malformation with hoarseness were retrospectively collected, which was composed of 5 men and 13 women, aged 3-71 with median age of 52. All the patients were admitted to the Affiliated Hospital of Qingdao University from January 1989 to January 2020. All patients underwent brain MRI and laryngoscopy. The patient's symptoms and first diagnosis department, diagnosis time, total course of disease, hoarseness course, diagnosis and treatment, and postoperative recovery time were summarized. Follow-up time was 3-16 years, with median follow-up time of 6.5 years. Descriptive methods were used for analysis. Results: The first visit departments of 18 patients included neurology (9 cases), otorhinolaryngology head and neck surgery (5 cases), pediatrics (2 cases), orthopedics (1 case) and respiratory department (1 case). Except for the 7 cases in neurology department, the other 11 patients were not diagnosed in time. The disease duration of 18 patients with Chiari malformation ranged from 2 months to 5 years, and hoarseness was present from 20 days to 5 years. After diagnosis, 9 patients underwent posterior fossa decompression surgery, and 1 of them underwent syrinx drainage at the same time. The symptoms of 8 cases improved significantly after operation, with the improvement time from 1 to 30 days. In addition, 9 patients chose conservative treatment, among whom 8 had no improvement in symptoms and 6 progressed. Conclusions: Posterior fossa decompression is an effective treatment for Chiari malformation, and the prognosis is good. Timely diagnosis and treatment can improve the prognosis of patients.

Piomiositis de los obturadores tratada con drenaje percutáneo guiado por ecografía en un niño. Presentación de un caso / Obturator pyomyositis in a pediatric patient resolved by ultrasound-guided percutaneous drainage. Case report

El objetivo de esta presentación es dar a conocer el manejo de la miositis piógena del músculo obturador interno en un paciente pediátrico que fue tratado mediante un drenaje percutáneo guiado por ecografía. Se trata de un niño de 5 años de edad, con manifestaciones clínicas y valores de laboratorio de infección muscular profunda en el obturador interno. Se identificó específicamente con resonancia magnética, es un área de difícil acceso quirúrgico, por lo cual se realizó un tratamiento percutáneo guiado por ecografía que permitió drenar el contenido purulento de la zona afectada. La resonancia magnética hizo posible lograr un diagnóstico más acertado en los casos de infección piógena temprana y, a su vez, decidir la vía de abordaje más adecuada. En ocasiones, se puede optar por la guía ecográfica con la cual se evita el abordaje quirúrgico formal y así disminuyen las complicaciones de la herida y la mayor morbimortalidad. La adición de procedimientos percutáneos guiados por imágenes es una herramienta muy útil para tratar enfermedades infecciosas y una gran ayuda para el ortopedista. Nivel de Evidencia: V

The objective of this case report is to present the management of a case of pyogenic myositis of the obturator muscle in a pediatric patient using ultrasound-guided percutaneous drainage. The patient is a 5-year-old pediatric patient with clinical and laboratory manifestations of deep muscular infection at the obturator level, an area of difficult surgical access, for which the least invasive treatment possible was used to drain purulent content from the affected area. The use of magnetic resonance imaging studies allows for a more accurate diagnosis in cases of early pyogenic infection, as well as determining the most effective approach to treatment. In some cases, ultrasound guidance can be used to avoid a formal surgical approach, reducing wound complications and morbidity and mortality. The addition of image-guided percutaneous procedures is a very useful tool for the treatment of infectious diseases and a great help to the orthopedist. Level of Evidence: V
