Boerhaave’s syndrome: Primary repair vs. esophageal resection—Case reports and meta-analysis of the literature

Boerhaave’s syndrome is a life-threatening disease with a high mortality. With regard to the heterogeneity of treatment strategies, no comparative studies exist and recommendations remain controversial. Seventeen cases of Boerhaave’s syndrome operated on between 1989 and 2000 at our hospital were reviewed retrospectively to compare the time period between perforation and diagnosis, and the morbidity and mortality among the different treatment options. In addition, we conducted a meta-analysis of the literature including all series containing five or more patients and compared the findings with our own data. Our patients with a perforation history of less than 12 hours showed significantly fewer signs of sepsis compared to patients with a history of more than 12 hours. In a comparison of patients with primary repair vs. patients treated with esophageal resection or an exclusion operation, no differences were found. In the literature, patients with a long period of perforation (more than 24 hours) were treated more often with an esophageal resection than patients with primary repair. In cases of Boerhaave’s syndrome, primary suturing of the esophageal perforation should be reserved only for those patients presenting within 12 hours after perforation. In all other cases, depending on the extent of the tissue damage, a two-stage esophageal resection with cervical esophagostomy and gastrostomy is recommended as the safest treatment.     

Congenital high airway obstruction syndrome: natural history and management

Background

Congenital high airway obstruction syndrome (CHAOS) is a life-threatening condition with a poorly understood natural history.

Methods

A retrospective review of five patients with CHAOS between 1997 and 2002 was performed.

Results

All fetuses had large echogenic lungs, dilated airways, inverted diaphragms, and massive ascites. One fetus with a laryngeal cyst was terminated at 22 weeks. A twin fetus with findings suggestive of a tracheal web had progressive hydrops, which led to fetal demise. The remaining 3 patients delivered via the ex utero intrapartum treatment (EXIT) procedure survived. The first patient tolerated progressive hydrops for 12 weeks in utero. He had tracheal atresia but underwent laryngotracheoplasty successfully. He is the first long-term CHAOS survivor and is speaking at 5 years of age. The 2 patients with relatively stable lung volumes prenatally have laryngeal atresia with a pinpoint posterior laryngeal fistula. Their postnatal clinical courses were much more benign than the first survivor.

Conclusions

The prenatal natural history and postnatal course of CHAOS depends on whether the airway obstruction is complete. The EXIT procedure offers the potential for salvage of this otherwise lethal condition. Hydrops may be well tolerated prenatally for weeks with potential resolution if airway fistulization is present.     

不稳定Hangman骨折的手术治疗

Objective To investigate the clinical effects of pedicle screw fixation in the treatment of unstable Hangman fractures. Methods From October 2001 to April 2006, 15 patients with the unstable Hangman fractures were treated by the pedicle screw fixation after skull traction and reduction through posterior cervical approach. By Levine-Edwards classification, there were 3 cases of Ⅱ type, 4 cases of ⅡA type, 8 cases of Ⅲ type. Results The mean follow-up time was 17 (3 to 30) months. Six cases of Grade D by Frankel classification recovered to Grade E. Postoperative X-rays revealed bony union in all cases. No screw loosening or obvious functional limitation of the cervical vertebrae was found. In the cases of incomplete reduction, C2, 3 fixation was performed for patients without severe dislocation, and additional CA fixation with lateral mass screw was supplemented for patients with serere dislocation. Conclusion Posterior pedicle screw fixation of C2,3 or C2-4 is an effective and safe method for treating the unstable Hangman fractures.     

Acne treatment with a 1,450 nm wavelength laser and cryogen spray cooling

BACKGROUND AND OBJECTIVES: A laser with a wavelength in the mid-IR range targeting the depth in skin where sebaceous glands are located in combination with cryogen spray cooling was evaluated for treatment of acne. In this non-ablative treatment, the laser energy heats the dermal volume encompassing sebaceous glands whereas the cold cryogen spray preserves the epidermis from thermal damage. STUDY DESIGN/MATERIALS AND METHODS: Monte Carlo simulations and heat transfer calculations were performed to optimize the heating and cooling parameters. A variety of heating and cooling parameters were tested in an in vivo rabbit ear study to evaluate the histological effect of the device on sebaceous glands and skin. Similar experiments were performed on ex vivo human skin. A clinical study for the treatment of acne on backs of human males was also conducted. RESULTS: Monte Carlo simulations and heat transfer calculations resulted in a thermal damage profile that showed epidermal preservation and peak damage in the upper dermis where sebaceous glands are located. Ex vivo human skin histology confirmed the damage profile qualitatively. In vivo rabbit ear histology studies indicated short-term thermal alteration of sebaceous glands with epidermal preservation. In the human clinical study on the back, a statistically significant reduction in lesion count on the treated side compared to the control side was seen (p < 0.001). Side effects were transient and few. CONCLUSIONS: The studies reported here demonstrate the feasibility of treating acne using a photothermal approach with a mid-IR laser and cryogen cooling.     

Splenectomy versus medical treatment for idiopathic thrombocytopenic purpura

BACKGROUND: Treatment strategies for idiopathic thrombocytopenic purpura (ITP) are still uncertain and its management is primarily empirical. The aim of this study was to investigate the role of splenectomy in the therapy of ITP and to evaluate whether medical or surgical treatment is superior. METHODS: Ninety-two patients with ITP were included in the study. All of these patients had medical therapy and 38 of them underwent splenectomy subsequently. Follow-up was completed in 91 patients after a median of 64 months. RESULTS: Side effects of medical therapy were noticed in 32 patients (35%), whereas after surgery only 2 patients (5%) had minor complications. A complete or partial remission was achieved in 35 patients (92%) after splenectomy, whereas this was achieved in only 27 patients (30%) after medical therapy. On multivariate analysis splenectomy and age were the only significant independent factors for complete and partial remission. CONCLUSIONS: Splenectomy is highly effective and safe in the treatment of ITP and is superior over medical therapy. These results should stimulate the discussion about splenectomy for ITP, possibly establishing evidence-based guidelines for surgical treatment in hematology.     

动脉瘤性蛛网膜下腔出血后脑血管痉挛的低温治疗

脑血管痉挛(cerebral vasospasm,CVS)是导致动脉瘤性蛛网膜下腔出血(aneurysm subarachnoid hemorrhage,aSAH)患者死亡和残疾的主要原因之一.人们对SAH后CVS进行了广泛的研究,认为红细胞分解产物、血管内皮功能障碍以及分子机制在其发病起关键作用.目前对脑血管痉挛的治疗尚无确切治疗方法,近年来人们尝试应用低温治疗脑血管痉挛,现就SAH后CVS的病理生理机制和低温对于CVS的治疗进展作一综述.     

Quality of life in GERD patients: Medical treatment versus antireflux surgery

Medical and surgical treatments are able to improve symptoms in patients with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the outcome in GERD patients without therapy, under continuous medical treatment, and after laparoscopic antireflux surgery. Five hundred seventy-nine consecutive patients underwent medical or surgical treatment for GERD-induced symptoms. Patients were studied in detail before and after treatment by means of a symptom questionnaire, endoscopy, esophageal manometry, 24-hour esophageal pH monitoring, and a barium esophagogram. In addition, quality of life was measured by the means of the Gastrointestinal Quality of Life Index (GIQLI) and the Health-Related Quality of Life (HRQL) questionnaire. Surgery was indicated and performed in 351 patients with persistent or recurrent GERD symptoms and/or complications, and in patients preferring surgery to medical treatment, despite the use of an adequate medication. The remaining 228 patients were treated with proton pump inhibitors (PPI) in the standard dose, or if required, the double dose. The outcome was assessed 3 and 12 months after treatment. While symptoms and quality of life were highly impaired in GERD patients without therapy compared with normal people, a significant improvement was obtained by PPI therapy. Following surgery, quality of life was normalized in all subsections and was significantly higher compared with the medically treated group. These results stayed constant in short-term and intermediate follow-up. Medical and surgical therapies are both able to improve symptoms and quality of life in GERD patients. Nevertheless, the outcome is significantly better following surgery. It can be suggested that surgical treatment may be the more successful therapy in the long-term.
