Periodontal therapy for hopeless mandibular anterior teeth: a retrospective case report with a multidisciplinary approach and a 20-year follow-up

Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Quistes Dentígeros Asociados a Mesiodens. Revisión de la Literatura a Propósito de Dos Casos

El mesiodens es el diente supernumerario que se origina en la premaxila, siendo considerado el más prevalente o el más diagnosticado debido a las numerosas alteraciones que producen y que incluyen malposición de los dientes permanentes, formación de diastemas, retraso en la erupción de los incisivos anteriores superiores, y formación de quistes. La etiología de los mesiodens no está completamente comprendida, aunque se piensa que pueda deberse a la proliferación de la lámina dental u otros factores genéticos. El diagnóstico generalmente es tardío debido a que la mayoría permanece sin erupcionar, pudiendo generar complicaciones dentomaxilares que finalmente son el motivo de consulta de los pacientes. El quiste dentígero es un quiste odontogénico del desarrollo asociado a la corona de un diente incluido, numerario o supernumerario y su tratamiento es quirúrgico. El diagnóstico temprano y la planificación del tratamiento debe considerar una anamnesis minuciosa, un examen clínico e imágenes 3D. La cirugía debe consistir en la desinclusión del diente causal, la exéresis y legrado de la lesión, con o sin regeneración ósea inmediata del lecho quirúrgico con injerto. Se presentan dos casos de quiste dentígero asociado a un mesiodens que se diagnosticaron como hallazgo radiográfico. El plan de tratamiento consistió en evaluación y tratamiento endodóntico de los dientes desvitalizados, enucleción y legrado del quiste, junto a la desinclu sión del diente supernumerario, y seguimiento clínico y radiográfico en el largo plazo.

Mesiodens is the supernumerary tooth that originates in the premaxilla, considered the most prevalent or, the most diagnosed due to the multiple alterations that produce and that include malposition of the permanent teeth, formation of gaps, delayed eruption of the upper anterior incisors and cyst formation. The etiology of mesiodens is not fully established, although it is thought that it may be due dental lamina alteration or other genetic factors. Diagnosis is usually late because most remain unerupted, and can generate dentomaxillary complications that are ultimately the reason for patient consultation. The dentigerous cyst is a developmental odontogenic cyst associated with the crown of an included, numerary or supernumerary tooth and its treatment is surgery. Early diagnosis and treatment planning should consider a careful history, clinical examination, and 3D imaging. The surgery must consist of the disinclusion of the offending tooth, the exeresis and curettage of the lesion, with or without immediate bone regeneration of the surgical bed with a graft. Two cases of a dentigerous cyst associated with a mesiodens that were diagnosed as a radiographic finding are presented. The treatment plan consisted in evaluation and endodontic treatment of devitalized teeth, enucleation and curettage of the cyst, together with the disinclusion of the supernumerary tooth, and long-term clinical and radiographic follow-up.

Classification of interventional therapy and ICD coding of hepatic malignant tumors:a case study / 现代医院

Interventional therapy for hepatic malignant tumours primarily includes cardiovascular system surgery,diges-tive system surgery,and various diagnostic and therapeutic procedures.Referring to the"International Classification of Diseases,Ninth Edition,Clinical Modification,ICD-9-CM-3"(2011 revision),the relevant surgical procedure codes on the front page of the case are contained mainly in the 9th chapter for cardiovascular system surgery,the 11th chapter for digestive system surgery,and the 18th chapter for various diagnostic and therapeutic procedures and other related chapters on diagnostic and therapeutic procedures.It has become a challenge for the history coders to complete the first page of interventional surgery cases by reviewing the surgery records,extracting the surgical steps,and then identifying the appropriate surgery codes and their sequencing.Accord-ing to the current classification of interventional therapy for hepatic malignant tumors,it is suggested to conduct the search and re-trieval using the keywords like"arteriography""embolization""perfusion""implantation""destruction"and"ablation".

Incidence and risk factors of post dural puncture headache after spinal anesthesia in Tripoli Hospitals

Post Dural Puncture Headache (PDPH) remains a prominent clinical concern to the present day and common complication seen in the field of anesthesiology and pain medicine. Identification of such risk factors is a crucial step in the rational modification of anesthetic practice and evaluation of therapeutic interventions. This study was conducted to demonstrate the incidence and risk factors of PDPH in patients after spinal Anesthesia during three days' post operations at general hospital in Tripoli, Libya. In this study certain factors related to patient history, baseline clinical state or anesthetic technique might be associated with an increased risk for this side effect, so it was collected historical, physiologic, and technical data to determine their association with PDPH. Out of total of 100 patients distributed over 5 different hospitals admitted over a period (from November 2020 to April 2021) 27% of them have a PDPH, while 92.5% of cases with PDPH are females, that 55.6% of PDPH cases are between 20 and 25 years old, and this percentage getting smaller as patients get older, most of the operations were caesarean section, at a rate of 58%, followed by lower abdominal surgeries with 19% of cases, and orthopedic surgeries with 17% of cases, while the lowest percentage was for the Urologic surgeries. 55% of cases with PDPH are classified as (case I), and 44% of them are classified as (case II), 81.5% of PDPH cases used noncutting needles. In this study the PDPH remains the most problem in hospitalized patients after spinal Anesthesia at Tripoli hospitals can be caused by variety of risk factors, associated with ASA physical states, nonprofessional technique, the females are more common than males and the percentage increasing in early age group

Portal thrombosis after surgical treatment of schistosomatic portal hypertension

SUMMARY OBJECTIVE: Several studies have investigated the correlation between the effects of different surgical treatments and laboratory exams for schistosomal portal hypertension, especially concerning portal system thrombosis. The etiopathogenic factors of this thrombosis are not fully understood. In this study, the correlation between surgical treatment for schistosomal portal hypertension and the occurrence of postoperative portal system thrombosis was investigated. METHODS: A total of 61 patients who underwent surgical treatment for schistosomal portal hypertension were distributed into four groups: Patients in Group 1 (n=12) underwent portal variceal disconnection associated with splenic artery ligation and spleen preservation. Patients in Group 2 (n=20) underwent portal variceal disconnection and total splenectomy. Patients in Group 3 (n=20) underwent portal variceal disconnection with subtotal splenectomy, preserving the upper splenic pole supplied by the splenogastric vessels. Patients in Group 4 (n=9) underwent portal variceal disconnection with total splenectomy and autogenous splenic implants on the greater omentum. Late postoperative portal vein thrombosis was diagnosed using Doppler ultrasound. RESULTS: Over the 10-year follow-up, portal vein thrombosis occurred in 26 operated patients (42.6%), with no significant difference observed among the four surgical groups (p=0.217). Most of the thrombi only partially occluded the portal system veins. All the patients presented with a thrombus inside the portal vein. There was no difference in hematological and biochemical tests between groups with or without portal vein thrombosis. CONCLUSIONS: Portal vein thrombosis is often observed in the late postoperative period, irrespective of the surgical treatment employed, and is not associated with patient characteristics or any hematological and biochemical tests.

Implante de válvula aórtica percutánea por acceso transcarotídeo: reporte del primer caso realizado en Chile / Percutaneous aortic valve replacement by trans-carotid approach: First case in Chile

La indicación en el implante de la válvula aortica percutánea (TAVI) se ha incrementado considerablemente en los últimos años, utilizando de preferencia el acceso transfemoral (TF), sin embargo, no queda claro cual debería ser la 2 vía de preferencia ante contraindicaciones a esta última. Presentamos un paciente de 81 años con alto riesgo quirúrgico en quien luego de discusión con heart team se decidió realizar TAVI y posterior a la identificación de obstrucción de la luz aortica descendente de 50%, se decidido realizar acceso transcarotideo izquierdo. Numerosos abordajes alternativos a la vía TF han sido descriptos en los últimos años. La vía transcarotidea ha sido la de mejores resultados en distintas revisiones clínicas y la que se ha presentado como 2° alternativa a la TF en algoritmos establecidos. Reportamos el primer implante de TAVI por vía transcarotidea en el hospital las Higueras, Chile.

The indication for percutaneous aortic valve implantation (TAVI) has increased considerably in recent years, preferably using transfemoral access (TF); however, it is not clear which should be the preferred access in the event of contraindications to the latter. We present an 81-year-old patient with high surgical risk in whom a 50% obstruction of the descending aortic lumen was identified and so, a left transcarotid access was chosen. Numerous alternative approaches to the TF approach have been described in recent years. The transcarotid approach has been the one with the best results in different clinical reviews and the one that has been presented as the second alternative to TF in established algorithms. We report the first transcarotid TAVI implantation in Las Higueras Hospital, Talcahuano, Chile.

Endoscopic or Microscopic Tympanoplasty Advantages and Disadvantages: A Theory Domain Systematic Review

Abstract Introduction Tympanoplasty is a reparative surgery that has multiple indications. The aid of a microscope or an endoscope is necessary to carry out the procedure. The classic method utilizes the microscope; however, in the recent decades, the endoscope has been popular. Although many articles try to compare these two techniques, there is still no robust evidence that confirms the superiority of either technique. In the present work, we seek to perform a systematic review contribute with this discussion. Objectives The present systematic review attempted to compare endoscopic and microscopic surgery techniques and to discover whether there would be superiority in the results of any of them, based on data currently available in the literature. Data Synthesis The objectives of the present review were organized according to the PICO planning and strategy adapted for systematic reviews. The inclusion and exclusion criteria were established aiming to select only select primary data. The main medical databases were searched usingan optimized search string with appropriate descriptors. The searched databases were MEDLINE, LILACS, SciELO, and EMBASE. A total of 99 studies were selected and 38 were fully assessed after the inclusion criteria were applied. All included articles were reviewed by all authors and their results were discussed and summarized. Conclusion The endoscopic technique was shown to be a safer technique comparable in effectiveness to the use of microscopy. In addition, it provides possible advantages such as shortening the surgical time and better postoperative pain outcomes.

Outcomes of endoscopic percutaneous suture lateralization for neonatal and infantal bilateral vocal ford paralysis

Abstract Objective: Bilateral Vocal Fold Paralysis (BVFP) is a rare but significant resource of respiratory distress in neonates and infants. The objective of this study was to evaluate the efficacy and functional outcomes of Endoscopic Percutaneous Suture Lateralization (EPSL) for the treatment of BVFP in neonates and infants. Methods: A case series study of nine patients undergoing EPSL for BVFP between January 2019 and June 2021 was conducted. All patients were candidates for tracheostomy prior to EPSL. Demographic features including gender, age at diagnosis and surgery, main symptoms, airway comorbidities, airway support, and etiology were collected preoperatively. Patients were evaluated for breathing, swallowing and phonation postoperatively. Surgical success was defined as the ability to avoid tracheostomy. Functional Endoscopic Evaluation of Swallowing (FEES) was conducted to identify aspiration. Voice evaluation was based on clinical observation. Results: Nine patients underwent ten EPSL procedures (one in the left vocal fold, and nine in the right vocal fold). Eight patients (8/9) were able to successfully avoid tracheostomy and feed orally without aspiration after the procedure. One patient experienced clinical improvement in respiratory support requirements and underwent laparoscopic nissen and gastrostomy tube placement. At the last follow-up, two patients regained normal voice, two patients had mild dysphonia, and five patients had moderate dysphonia. Five patients showed partial return of the contralateral vocal fold function. Conclusion: EPSL is an effective and safe treatment for neonatal and infantal BVFP, which enables patients free from tracheostomy without significant impact on swallowing function or phonation. Level of evidence: Level 4.

COVID-19 Impact on Operative Management of Pediatric Neck Abscesses

Abstract Introduction For multiple reasons, elective pediatric otolaryngology surgical procedures have declined during the COVID-19 pandemic. Objective The purpose of the present study was to assess whether the prevalence of pediatric neck abscesses managed with operative drainage decreased compared with previous years. Methods Medical records of all pediatric cases at a tertiary care children's hospital diagnosed with abscess of the neck and treated with incision and drainage were evaluated between the dates of April 1 and November 30 from 2015 to 2020. Outcomes were compared for each year from 2015 to 2019 to 2020, which included location, abscess size, duration of antibiotic treatment, microbiology, and the number of cases per year. Results A total of 201 cases were included. The mean ± standard deviation (SD) presenting age in the 2015 to 2019 group was 5.05 ± 5.03 years old and 2.24 ± 1.91 years old in the 2020 group. The mean number of cases between 2015 and 2019 was 35.6 ± 4.2, whereas the number of cases in 2020 was 23 (p = 0.002). Of those patients who underwent IV antibiotic therapy prior to presentation (n = 43), the mean number of days before admission was 1.98 ± 2.95 (n = 40) from 2015 to 2019 and 12.00 ± 10.39 (n = 3) in 2020 (p = 0.008). The percent of cases with multiple strains cultured between 2015 and 2019 was 13.4% versus 18.2% in 2020 (p = 0.007). Conclusion There was a decrease in the number of operative neck abscesses in 2020 compared with the mean number per year from 2015 to 2019. COVID-19 mitigation strategies leading to reduced transmission of other viral and bacterial illnesses and a tendency toward prolonged medical management to avoid surgery are two possible explanations.

Trifocal intraocular lens implantation to treat visual demands in Mongolian patients / Монголын Анагаах Ухаан

Introduction@#Intraocular lens (IOL) implants are monofocal and trifocal lenses which helps to clear up the vision after cataract surgery.@*Goal@#In this work, we aimed to compare the monofocal and trifocal IOL implantation during phacoemulsification surgery.@*Materials and Methods@#This study was conducted on 133 participants. Females comprised n=81, mean n=52 into equal groups. Preoperative and Postoperative cataract surgery UCVA and BCVA were measured and compared during the after 1 day, week 1, 2 weeks and month1. @*Statistical analysis@#The results of the study were processed using the SPSS 25.0 program after coding the data and checking for typographical errors. The normality of the data distribution was tested by inspecting a histogram. Categorical variables were compared using the chi-square test or Fisher's test. Statistical significance was determined at a p-value lower than 0.05@*Ethical statement@#The study was approved by the Research Ethics Committee of the Mongolian National University of Medical Sciences (No.2021/05/21).

The expression and significance of protease activated receptor 2 in ovarian epithelial carcinoma / 中华肿瘤杂志

Objective: To investigate the expression and significance of protease activated receptor 2 (PAR2) in ovarian epithelial carcinoma. Methods: PAR2 mRNA expression levels in 410 cases of epithelial ovarian carcinoma and 88 cases of human normal ovary were analyzed from cancer Genome Atlas (TCGA) database and tissue genotypic expression database (GTEx). Immunohistochemical (IHC) staining of PAR2 protein was performed in 149 patients with ovarian cancer who underwent primary surgical treatment at Cancer Hospital of Chinese Academy of Medical Sciences. Then the relationship between mRNA/protein expression of PAR2 and clinicopathological features and prognosis was analyzed. Gene functions and related signaling pathways involved in PAR2 were studied by enrichment analysis. Results: The mRNA expression of PAR2 in epithelial ovarian carcinoma was significantly higher than that in normal ovarian tissue (3.05±0.72 vs. 0.33±0.16, P=0.004). There were 77 cases showing positive and 19 showing strong positive of PAR2 IHC staining among the 149 patients, accounting for 64.4% in total. PAR2 mRNA/protein expression was closely correlated with tumor reduction effect and initial therapeutic effect (P<0.05). Survival analysis showed that the progression free survival time (P=0.033) and overall survival time (P=0.011) in the group with high PAR2 mRNA expression was significantly lower than that in the low PAR2 mRNA group. Multivariate analysis showed tumor reduction effect, initial therapeutic effect were independent prognostic factors on both progression-free survival and overall survival (P<0.05). The progression-free survival (P=0.016) and overall survival (P=0.038) of the PAR2 protein high expression group was significantly lower than that of the low group. Multivariate analysis showed PAR2 expression, initial treatment effect and chemotherapy resistance were independent prognostic factors on both progression-free survival and overall survival (P<0.05). Based on Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), PAR2 target genes were mainly enriched in function related to intercellular connection, accounting for 40%. Gene enrichment analysis (GSEA) showed that the Wnt/β-catenin signaling pathway (P=0.023), the MAPK signaling pathway (P=0.029) and glycolysis related pathway (P=0.018) were enriched in ovarian cancer patients with high PAR2 mRNA expression. Conclusions: PAR2 expression is closely related to tumor reduction effect, initial treatment effect and survival of ovarian cancer patients. PAR2 may be involved in Wnt/β-catenin signaling pathway and intercellular connection promoting ovarian cancer invasion and metastasis.

OBJECTIVE@#To compare the clinical efficacy of full endoscopic lamina fenestration discectomy (Endo-LOVE) with full endoscopic transforaminal approach discectomy in the treatment of degenerative lumbar lateral recess stenosis.@*METHODS@#A retrospective analysis of 48 patients with degenerative lumbar lateral recess stenosis between March 2018 and March 2019 was performed. There were 32 males and 16 females, aged from 60 to 83 years old with an average of (72.9±6.5) years, course of disease ranged from 5 to 16 years with an average of (8.0±2.8) years. The patients were divided into observation group and control group according to surgical approaches. There were 28 cases in observation group, underwent Endo-LOVE surgery;and 20 cases in control group, underwent full endoscopic foraminal approach discectomy. The operation time, intraoperative blood loss, hospitalization day and complications were observed between two groups. Visual analgue scale (VAS), Japanese Orthopaedic Association(JOA), Oswestry Disability Index(ODI), lateral crypt angle were compared between two groups. And clinical effects were evaluated by modified Macnab standard.@*RESULTS@#There was no significant difference in follow-up and operation time between two groups (P>0.05). Intraoperative blood loss was from 5 to 15 ml with an average of (8.4±3.6) ml in observation group and 5 to 25 ml with an average of (11.5±5.4) ml in control group. The hospitalization day was from 5 to 8 days with an average of (6.0±1.0) days in observation group and 6 to 9 days with an average (7.2±1.1) days in control group. Intraoperative blood loss and hospitalization day were significantly lower in observation group(P<0.05). There were no serious complications in both groups. The VAS, JOA scores, and ODI at 3-month and final follow-up were significantly improved in both groups (P<0.05), and observation group was significantly better than control group (P<0.05). The skeletal lateral crypt angle and soft lateral crypt angle were significantly greater than the preoperative angle at 3 days postoperatively(P<0.05), and observation group was significantly better than control group(P<0.05). At the final follow-up, the modified Macnab criteria was used to assess clinical efficacy, in observation group, 22 patients obtained excellent results, 5 good and 1 fair;while 11 excellent, 4 good and 5 fair in control group;the clinical efficacy of observation group was significantly better than that of control group(P<0.05).@*CONCLUSION@#Both surgical methods are performed under direct vision, with high safety and good clinical efficacy. However, Endo-LOVE enlarged the lateral crypt more fully.

Comparative analysis of clinical efficacy between posterior percutaneous endoscopic discectomy and anterior cervical discectomy and fusion in the treatment of cervical spondylotic radiculopathy / 中国骨伤

OBJECTIVE@#To explore the clinical efficacy of posterior percutaneous endoscopic discectomy(PPECD) in the treatment of cervical spondylotic radiculopathy.@*METHODS@#A total of 56 patiens with single segment cervical spondylotic radiculopathy from December 2017 to October 2020, were randomly divided into observation group and control group. In observation group, there were 16 males and 11 females, including 8 cases of C4,5, 13 cases of C5,6 and 6 cases of C6,7 performed posterior percutaneous endoscopic discectomy, aged from 34 to 61 years old with an average of (51.15±6.29) years old. In control group, there were 19 males and 10 females with single segment cervical spondylotic radiculopathy including 10 cases of C4,5, 14 cases of C5,6 and 5 cases of C6,7 performed anterior cervical discectomy and fusion, aged from 40 to 65 years old with an average of (53.24±5.31) years old. The operative time, intraoperative blood loss, postoperative time of lying in bed and length of postoperative hospital stay were recorded. Visual analogue scale(VAS) and neck disability index(NDI) were used to evaluate the clinical efficacy. Cervical plain films or MRIs, CTs were taken for re-visiting patients.@*RESULTS@#All patients were followed up more than 2 years. The observation group patients were followed up, the duration ranged from 24 to 42 months with an average of (30.48±4.91) months. The control group patients were followed up, the duration ranged from 25 to 47 months, with an average of (32.76±4.53) months. Compared with control group, operative time, intraoperative blood loss, postoperative time of lying in bed and length of postoperative hospital stay were decreased(P<0.05). Compared with pre-operation, VAS of neck and upper limb and NDI at the latest follow-up between two groups were significantly improved(P<0.05). Compared with control group, VAS of neck and upper limb at 1 day after operation in observation group were significantly reduced(P<0.05). There was no significant difference in VAS of neck and upper limb and NID at 1, 3 months and the latest follow-up after operation between two groups(P>0.05). In the observation group, one patient's deltoid muscle strength was weakened to grade 4 after operation, and returned to normal after 12 weeks of conservative treatment. In control group, there was 1 case of postoperative adjacent spondylosis with symptoms of spinal compression after 2 years operation, then underwent cervical artificial intervertebral disc replacement. And there was 1 case of dysphagia after operation in control group and improved after 1 year. There was no significant difference in incidence of complications between two groups.@*CONCLUSION@#PPECD has advantages of shortening operative time, decreasing intraoperative blood loss, reducing postoperative time of lying in bed and length of postoperative hospital stay. However, applicable age range of patients and long-term clinical efficacy needs further study.

Comprehensively promoting the application of whole-course nutritional management in surgery / 中华消化外科杂志

Surgery is the main approach for treating surgical diseases, but it can bring traumatic stress to the body, causing metabolic changes and nutritional deficiencies. In addition to the primary surgical disease, the underlying health condition can also have an impact, and thus, at different stages, including preoperative, intraoperative, postoperative, and post-discharge, surgical patients often experience varying degrees of metabolic changes and malnutrition. These metabolic changes and nutritional deficiencies at any stage can mutually influence each other, ultimately reducing the therapeutic effect of surgical treatment and affecting both short-term and long-term clinical outcomes. The concept and techniques of nutritional therapy have undergone rapid deve-lopment in recent decades, greatly improving the success rate of disease treatment. It is recommen-ded to promote the application of whole-course nutritional management in surgery, which integrates nutritional screening, assessment, and intervention throughout the entire process of preoperative, intraoperative, postoperative, and post-discharge care during the disease treatment and recovery process. This approach can maximize the therapeutic benefits of nutritional therapy, accelerate postoperative recovery, and improve patient′s prognosis. Based on clinical practices and literatures, the author explores the importance and necessity, primary tasks, key measures, and final guarantees of whole-course nutritional management.

Objective:To compare the clinical efficacy of laparoscopic pelvic floor three-level internal repair and stapled transanal rectum resection (STARR) in the treatment of male patients with intrarectal prolapse. Mlethds A total of 101 male patients with rectal intrarectal prolapse from Feb 2013 to Oct 2017 were enrolled into this study. Fifty-two patient in group A received laparoscopic pelvie floor three-level internal repair, and 49 patients in group B received STARR. The Wexner incontinence scale (WIS), Wexner constipation scale (WCS) score, gastrointestinal quality of life index (GIQLI) and degree of internal rectal prolapse (DIRP) were systematically evaluated before surgery and 3 months, 1 year and 3 years after surgery. Results:There were no significant differences in age, BMI, number of bowel movements(BM), WIS, WCS, GIQLI and DIRP between the two groups before surgery(all P>0.05). The WIS, WCS, GIQLI and DIRP in 3 months, 1year and 3 years after surgery in both two groups were significantly better than those before surgery ( t=20.169, 25.229, 27.278, 23.818, 23.489, 21.152, -3.550, -23.042, -22.901, 82.852, 40.915, 30.010, 11.323, 13.237, 11.452, 19.473, 18.647, 17.108, -8.791, -5.254, -5.846, 37.439, 30.598, 22.852, all P<0.001). The GIQLI in Group A was significantly better than that of group B at 1 year and 3 years after surgery ( P<0.001) but close to that in Group B at 3 months after surgery ( t=1.428, P=0.156). The WIS, WCS and DIRP in group A were significantly better than those in group B at 3 months, 1 year and 3 years after surgery, with statistical significance ( t=-8.243, -15.688, -20.193, -4.268, -4.768, -4.851, 11.329, 13.543, -5.399, -4.745, -4.598, all P<0.001). There was no signifcant difference in grade Ⅰ-Ⅲ complications between the two groups (χ 2=0.046, P=1.00). Conclusion:Laparoscopic pelvic floor three-level internal repair is more effective than transanal STARR in the treatment of male internal rectal prolapse.

Determine a surgical procedure for diabetic foot with chronic refractory wound / 中华显微外科杂志

Objective:To evaluated the options in selection of surgical procedures for treatment of the patients suffering from diabetic feet with chronic refractory wounds.Methods:From January 2020 to June 2021, 23 patients with diabetic feet complicated with refractory wounds were treated in Department of Hand Surgery, Shunde Heping Surgical Hospital. The patients were 15 males and 8 females, aged 51-86 years old and with an average age of 65 years old. All the patients had Type-II diabetes for over 5 - 22 years. Average blood glucose of the patients was found at 15.6 mmol/L on admission. Free anterolateral thigh perforator flaps (ALTPF) were used for reconstruction of the wound of diabetic feet in 19 patients, 2 patients received vascular bypass surgery and 2 had amputations. Regular outpatient follow-up were conduct on all patients after surgery.Results:Follow-up time lasted for 8 to 30 months, 12 months in average. At the last follow-up, the donor and recipient sites healed well in the 19 patients who received flap reconstruction, without an infection, necrosis and wound recurrence. Pains were significantly relieved after the surgery in the 2 patients who received vascular bypass surgery, and wounds all healed well after symptomatic treatment and dressing change without recurrence of wounds at the last follow-up. Average Maryland score of foot function was 84 for the patients who had limb salvage, and 2 patients were in excellent and 19 in good at the last follow-up. The 2 patients who had amputation successfully survived through the perioperative period, and the wounds healed well at the last follow-up.Conclusion:The treatment is complicated in the patient suffering from diabetic foot with chronic refractory wounds due to factors such as advanced age, co-existing and complicated underlying diseases together with the complex wounds. Most patients can achieve good prognosis in wound treatment of free flap transfer or vascular bypass surgery. However, a limb salvage is recommended with caution for the patients who have severe infections and dry gangrene.

Gradual traction-unlocking closed reduction technique for Tile C old pelvic fractures / 中华创伤骨科杂志

Objective:To explore the technical points and efficacy of gradual traction-unlocking closed reduction technique (GT-UCRT) for Tile C old pelvic fractures.Methods:From August 2012 to June 2021, 6 patients with Tile C old pelvic fracture were treated and followed up at Department of Orthopedics, The Fourth Medical Center, General Hospital of Chinese PLA. They were 4 males and 2 females with an age of (35.8±10.5) years. By Tile classification: 4 cases of type C1.2, 1 case of type C1.3, and 1 case of type C2; time from injury to surgery: 153.8 (64.3, 204.8) days. The 6 patients were treated with GT-UCRT. The time for gradual traction reduction, operation time, hospital stay, intraoperative blood loss and complications were recorded. The modified Matta score was used to evaluate the reduction quality of pelvic fractures, and the Majeed score was used to evaluate the pelvic function at the last follow-up.Results:The 6 patients were followed up for (40.3±22.9) months (from 12 to 72 months) after surgery. The time for gradual traction reduction was (26.7±4.6) days, operation time (119.2±4.6) minutes, hospital stay (11.5±2.9) days, and intraoperative blood loss (533.3±189.6) mL. By the modified Matta score, the pelvic reduction after surgery was rated as satisfactory in 5 cases and as unsatisfactory in 1 case. The length disparity between both lower limbs in the 6 patients was (6.9±1.6) cm before surgery and (1.0±0.4) cm immediately after surgery, showing a statistically significant difference ( t=11.135, P<0.001). One fracture healed 3 months after surgery and 5 fractures 6 months after surgery. The Majeed pelvic score at the last follow-up was (80.8±9.0) points for the 6 patients, yielding 2 excellent cases, 3 good cases and 1 fair case. Delayed wound healing was reported in 1 patient, calf intermuscular venous thrombosis in 2 cases, and emotional anxiety and sleep disorder in 1 patient. No new lumbosacral plexus injury was found in any patient. Conclusions:In the treatment of Tile C old pelvic fractures, since our self-designed GT-UCRT combines the advantages of Ilizarov technique and unlocking closed reduction technique, it can not only protect the lumbosacral plexus but also obtain satisfactory reduction of the fracture.

Clinicopathological features of intraabdominal bronchogenic cyst: an analysis of 8 cases / 中华全科医师杂志

Objective:To analyze the clinicopathological features of intraabdominal bronchogenic cyst.Methods:The clinical data of 8 patients with intraabdominal bronchogenic cyst admitted in 3 Grade-A tertiary hospitals in Yunnan province between 2014 and 2023 were retrospectively analyzed. The clinical and pathological features, diagnosis, treatment and prognosis of intraabdominal bronchogenic cyst were reviewed.Results:There were 1 male and 7 females with an mean age of 45±12 years (21-65 years). Two patients presented with abdominal pain and 5 asymptomatic patients were found during physical examination. The cysts were located in retroperitoneum in 4 cases, located between the pancreas tail, spleen and the posterior wall of the stomach in 2 cases, located in the posterior wall of the stomach in 1 case, and located close to left adrenal gland in 1 case. Two patients had elevated tumor markers, while tumor markers in the remaining 6 cases were normal. Seven cases underwent laparoscopic complete cyst resection and 1 case had open surgical resection. The wall of most cysts were lined with respiratory epithelium and composed of goblet cells or pseudostratified ciliated columnar epithelium. The wall of cysts was composed of fibrous connective tissue or smooth muscle bundles, and the cavity contained serous mucous glands. Two cases showed cartilage tissue and one showed the infiltration of large number of inflammatory cells. The mean follow-up time was 31±32 months (range 5-107 months), and no recurrence or metastasis was found during the follow-up.Conclusions:Abdominal bronchogenic cyst is often found in adulthood, and most cases are symptomatic and found during physical examination. The diagnosis mainly depends on pathological examination, and tumor markers are not specific for its diagnosis. Surgery is the best way for treatment.

Treatment experience of neck tumor surgeries involving carotid artery / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate surgical treatment of carotid artery diseases in neck tumor surgery. Methods:A retrospective analysis of the clinical data on carotid artery treatment was conducted in the five cases of neck tumor surgeries treated at Department of Surgical Oncology, the First Peoples Hospital of Lanzhou from March 2010 to May 2020. Surgical methods, including carotid artery resection and ligation, tumor-involved artery resection and vascular reconstruction, and tumor peeling and carotid rupture repairing were used, respectively. Results:Five cases were successfully operated on. One case of carotid artery ligation was followed by intermittent dizziness and decreased contra-lateral limb strength after the surgery. The remaining patients exhibited no neurological complications. A patient with cervical low-grade myofibroblastoma developed into lung metastases 8 months after the surgery. Another patient with cervical lymph node metastases in papillary thyroid cancer developed into lung metastases 24 months after the surgery. Conclusion:Currently, surgical methods for clinical treatment of diseased carotid arteries include carotid artery resection and ligation, simple tumor peeling, tumor invasion artery resection and vascular reconstruction, and interventional therapy. Each surgical method has its own advantages and disadvantages. Therefore, the choice of treatment depends on the patient's specific conditions, physician's clinical experience, and the equipment available.
