Transverse changes after surgically assisted rapid palatal expansion

The aim of this retrospective study was to investigate the amount of skeletal and dental expansion in patients submitted to surgically assisted rapid palatal expansion (SARPE). The sample consisted of 21 patients (14 female and seven male) with a mean age of 25.4 years (range 17.4–41.8 years). Postero-anterior (PA) cephalograms were taken pre-expansion (T1), immediately after expansion (T2), and at post-expansion retention of 120 days (T3). SARPE promoted significant transverse skeletal changes, which were maintained from T2 to T3. Dentoalveolar expansion and dental tipping were also observed in the region of the first molars and first premolars; however the net effect at the first molars was significantly less than that at the first premolars. No statistically significant effect on the width of the nasal cavity was observed. The findings indicate that peculiarities inherent to dental effects may influence the clinical options for SARPE. Skeletal expansions with SARPE were significant and stable. Dental changes were different between molars and premolars. The transverse changes after SARPE should be observed for future procedures related to the retention and the completion of orthodontic treatment.     

改良胰管空肠黏膜端侧吻合胰十二指肠切除术临床效果研究

目的探讨改良胰管空肠黏膜端侧吻合的胰十二指肠切除术临床效果。方法回顾性分析2016年1月至2019年3月62例行胰十二指肠切除术(PD)患者临床资料,其中30例行改良胰管空肠黏膜端侧吻合术(改良组),32例行传统胰管空肠黏膜端侧吻合术(传统组)。选用SPSS 20.00统计学软件进行数据分析,围术期相关指标和术后第1、3、5、7、9 d的腹腔引流液淀粉酶水平用(±s)表示,采用独立t检验;并发症发生率采用χ^2检验,P<0.05差异有统计学意义。结果改良组出血量明显小于传统组(P<0.05),其余相关围术期指标差异均无统计学意义(P>0.05);改良组术后发生1例胰瘘明显小于传统组9例(P<0.05),其中改良组B级胰瘘发生率明显小于传统组(P<0.05),生化瘘、C级胰瘘发生率、淋巴瘘、胃排空发生率比较差异均无统计学意义(P>0.05);两组患者腹腔引流液淀粉酶含量在术后第1、3、5、7、9 d的检测期间内,传统组腹腔引流液淀粉酶含量小于改良组(P<0.05)。结论改良胰管空肠黏膜端侧吻合术相比于传统胰管空肠黏膜端侧吻合术在PD中能有效降低胰瘘的发生率,具有一定的临床推广价值。     

Urethral advancement in hypospadias with a distal division of the corpus spongiosum: Outcome in 158 cases

ObjectiveOutcome of urethral mobilization and advancement (Koff procedure) in hypospadias with a distal division of the corpus spongiosum and redo cases with distal urethral failure.Materials and methodsFrom January 1999 to November 2012, 158 children with a distal hypospadias (115 primary cases and 43 redo cases) underwent surgical repair using the Koff technique with a median age at surgery of 21 months (range, 12–217 months).ResultsMean follow-up was 19 months (median, 14 months). Thirty patients (19%) presented with a complication (13.9% in primary cases and 32.5% in redo surgery) mostly at the beginning of our experience. Meatal stenosis was the most common one (3.5% in primary case, 6% overall). Ventral curvature (>10°), which is considered as a possible long-term iatrogenic complication of the Koff procedure, was not found in patients with fully grown penis except in one redo patient who had, retrospectively, an inadequate indication for this type of repair. Of 158 patients, 33 reached the age of puberty (>14 years old) with a mean follow-up of 34 months, only one presented with a significant ventral curvature.ConclusionUrethral mobilization and advancement is a reasonable alternative for anterior hypospadias and distal fistula repair in selected cases. It has two major advantages compared to other techniques: it avoids any urethroplasty with non-urethral tissue and eliminates dysplastic tissues located beyond the division of the corpus spongiosum, which may not grow at the same pace as the rest of the penis. Significant iatrogenic curvature in fully grown penis is not supported by this series.     

Esophageal positions relative to the left atrium; data from 293 patients before catheter ablation of atrial fibrillation

AimsThree-dimensional rotational angiography (3DRA) of the left atrium (LA) and the esophagus is a simple and safe method for analyzing the relationship between the esophagus and the LA during catheter ablation of atrial fibrillation. The purpose of this study is to describe the location of the esophagus relative to the LA and mobility of the esophagus during ablation procedure.MethodsFrom 3/2011 to 9/2015, 3DRA of the LA and esophagus was performed in 326 patients before catheter ablation of atrial fibrillation. 3DRAwas performed with visualization of the esophagus via peroral administration of a contrast agent. The positions of the esophagus were determined at the beginning of the procedure, for part of patients also at the end of procedure with contrast esophagography.ResultsThe most frequent position is behind the center of the LA (91 pts., 31.9%) The least frequent position is behind the right pulmonary veins (27 pts., 9.4%). The average shift of the esophagus position was 3.36 ± 2.15 mm, 3.59 ± 2.37 mm and 3.67 ± 3.23 mm for superior, middle and inferior segment resp.ConclusionsThe position of the esophagus to the LA is highly variable. The most common position of the esophagus relative to the LA is behind the middle and left part of the posterior wall of the LA. The least frequently observed position is behind the right pulmonary veins. No significant position change of esophagus motion from before to after the ablation procedure in the majority (≥95%) of the patients was observed.     

Surgical treatment of the severe thoracic gastrocutaneous fistula by pedicled muscle flap filling and thoracoplasty after oesophagectomy for oesophageal squamous cell carcinoma: A case report

Background: Thoracic anastomotic fistula (TAF) is a severe postoperative complication of oesophagectomy, and its occurrence coupled with a thoracic gastrocutaneous fistula (TGCF) and tracheostenosis is very unusual and may lead to a fatal consequence.Case presentation: We describe a case of an old female diagnosed with mid-oesophageal carcinoma, who presented with a TAF after oesophagectomy, which was healed by an effective treatment, while a severe TGCF and tracheostenosis appeared one month postoperation. The complications were detected by gastroscopy, barium oesophagogram and thoracic computed tomography (CT). Through surgical treatments, including pedicled muscle flap filling and thoracoplasty, and a correlated corrective procedure, the patient completely recovered and was discharged six months after the admission.Conclusion: Treatment by pedicled muscle flap filling and thoracoplasty after oesophagectomy for oesophageal squamous cell carcinoma can be a curative alternative for the severe thoracic gastrocutaneous fistula.
