This paper studies the effects of retailer's information-superiority on participant's profit in the existence of spot market. Two cases considered: manufacturer knows retailer's ...information-superiority and manufacturer does not know retailer's information- superiority. Our theoretical analysis and numerical experiments suggest that the appearance of spot market benefits retailer and system, but damages manufacturer. When manufacturer knows that retailer has better information, improved retailer's market-knowledge always benefits manufacturer and the system, but hurts the retailer himself. Whereas when manufacturer does not know retailer's information-superiority, improved retailer's market-knowledge greatly benefits the retailer and system, but decreases manufacturer's profit.
•This paper introduces a special immediate nipple reconstruction technique in two prosthesis reconstruction patients.•This technique uses the intercostal artery perforator (ICAP) pedicle to rebuild ...the nipples immediatly.•The reconstructed nipple made by this technique has ample blood supply, and the lower thoracic advancement flap facilitated the creation of the neo-inframammary fold.
Several techniques can be used for nipple reconstruction, including nipple sharing and skin graft technique, local flap technique, and autologous flap technique. A well-performed nipple-areola complex (NAC) reconstruction has several advantages. However,there is no one technique suitable for all kind of nipple-areola complex (NAC) reconstruction. Here, we introduce a special immediate nipple reconstruction technique in two prosthesis reconstruction patients.
Both patients received nipple sparing mastectomy before, but their nipples were found to be involved with cancer after the surgery. We used intercostal artery perforator (ICAP) pedicle to rebuild the nipples. We chose the pedicle under the inframammary fold, separated the ICAP flap with enough width and length, carefully kept the ICAP and detected blood supply with lysne crystal green. According to the fluorescence light, we cut off the ischemia part. The C-V nipple reconstruction technique was used to rebuild a nipple with intercostal perforator. The peri-areolar incision was shrunken by purse-string suture. The reconstructed nipple was put to the shrunken peri-areolar incision, and the lower thoracic advancement flap facilitated the creation of the neo-inframammary fold at last.
Through the evaluation of breast surface beautiful score (BSBs) and Breast-Q, both patients were satisfied with the results, and neither regretted the surgery. Neither of them wanted the tattoo of the NAC. After half a year follow-up, the reconstructed nipples survived well.
The ICAP flap is a good technique for immediate nipple reconstruction. The technique is advantageous because this flap has reliable blood supply, suitable volume, and covert scar. Appropriate selection of patients, coordinated planning and careful intra-operative management is the key points of this technique.
BACKGROUNDEsophageal perforation is a serious, but rare complication of high mortality following the endoscopic submucosal dissection (ESD) procedure. The aim of this study is to evaluate the ...efficacy and safety of nonsurgical treatment of esophageal perforations caused by ESD based on our clinical experience. METHODSFrom January 2009 to November 2013, 8 patients were diagnosed with endoscopic perforation of the esophagus caused by ESD in our center. All cases were treated with nonsurgical measures, such as metallic clips, conservative treatment alone and therapeutic drainage. RESULTSThe places of perforation were closured by metallic clips immediately in 4 patients. Two patients were cured with conservative treatment alone. Therapeutic drainage with large-bore tube thoracostomy was applied in another 2 patients who had empyema following esophageal perforation. All of the patients were treated nonsurgically, and recovered well. CONCLUSIONEsophageal perforation caused by ESD can be detected and treated timely, and nonsurgical treatment seems to be a feasible and effective option for clinicians.
