A transhiatal esophagectomy without thoracotomy and esophageal reconstruction with gastric transponsition was performed in a recurrent laryngeal carcinoma spread to cervical esophagus. There were several benefits to performing this method: 1) It could be performed in one stage, took shorter operating time, and provided safe and efficient palliation in the patient with esophageal carcinoma. 2) The possible maximum surgical margin was obtained and the incidence of suture line tumor recurrence was minimized. 3) Postoperative death from anastomotic disruption and secondary mediastinitis and sepsis were virtually eliminated. 4) Clinically significant gastroesophageal reflux rarely occured.

Purpose: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. Results: Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, $1.68{\pm}3.37$ vs. normal, $0.76{\pm}1.06$; p<0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio (p<0.05), friability and postprandial dominant frequency (p<0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency (p<0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, $33.59{\pm}15.52$ vs. normal, $28.10{\pm}17.23$; p<0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. Conclusion: In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.

The fact that long-term use of proton pump inhibitors (PPIs) aggravates corpus atrophic gastritis in patients with Helicobacter pylori infection has been proven clinically and experimentally. Corpus atrophic gastritis is a known risk factor for gastric cancer. Therefore, gastric neoplasia might be associated with the long-term use of PPIs. One of the causes of worsening corpus atrophic gastritis, leading to the development of adenocarcinoma, might be bacterial overgrowth under conditions of hypochlorhydria. The production of potentially carcinogenic N-nitrosocompounds by nitrosating organisms under conditions of hypochlorhydria might be associated with carcinogenesis. Interactions between bile acids, pH, and H. pylori might also contribute to carcinogenicity, especially in patients with gastro-esophageal reflux disease (GERD). The concentration of soluble bile acids, which have bactericidal or chemorepellent properties toward H. pylori, in gastric contents is considerably higher in patients undergoing continuous PPI therapy than in healthy individuals with normal acid production. Under these circumstances, H. pylori might colonize the stomach body rather than the pyloric antrum. Hypergastrinemia induced by PPI administration might promote the development of gastric cancer. Because the main cause of corpus atrophic gastritis is H. pylori infection, and not PPI administration, H. pylori infection should be eradicated before starting long-term PPI therapy.

Laparoscopic proximal gastrectomy (LPG) is theoretically a superior choice of minimally-invasive surgery and function-preserving surgery for the treatment of proximal early gastric cancer (EGC) over procedures such as laparoscopic total gastrectomy (LTG), open total gastrectomy (OTG) and open proximal gastrectomy (OPG). However, LPG and OPG are not popular surgical options due to three main concerns: the first, oncological safety; the second, functional benefits; and the third, anastomosis-related late complications (reflux symptoms and anastomotic stricture). Numerous recent studies have concluded that OPG and LPG present similar oncological safety profiles and improved functional benefits when compared with OTG and LTG. While OPG with modified esophagogastrostomy does not provide satisfactory results, OPG with modified esophagojejunostomy showed similar rates of anastomosis-related late complications when compared to OTG. At this stage, no standard reconstruction method post-LPG exists in the clinical setting. We recently showed that LPG with double tract reconstruction (DTR) is a superior choice over LTG for proximal EGC in terms of maintaining body weight and preventing anemia. However, as there is no definitive evidence in favor of LPG with DTR, a randomized clinical trial comparing LPG with DTR to LTG was recommended. This trial, the Korean Laparoscopic Gastrointestinal Surgery Study-05 (NCT01433861), is expected to assist surgeons in choice of surgical approach and strategy for patients with proximal EGC.

Purpose: The aims of this study were to make serial comparisons of the quality of life (QoL) between patients who underwent total gastrectomy and those who underwent distal subtotal gastrectomy for gastric cancer and to identify the affected scales with consistency. Materials and Methods: QoL data of 275 patients who were admitted for surgery between September 2008 and June 2011 and who underwent subtotal gastrectomy or total gastrectomy were obtained preoperatively and postoperatively at 3, 6, 9, 12, 18, and 24 months. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL. Results: QoL, as assessed by the global health status/QoL and physical functioning, revealed a brief divergence with worse QoL in the total gastrectomy group 3 months postoperatively, followed by rapid convergence. QoL related to restrictive symptoms (nausea/vomiting, dysphagia, reflux, and eating restrictions) and dry mouth was consistently worse in the total gastrectomy group during the first 2 postoperative years. Conclusions: The general QoL of patients after gastrectomy is highly congruent with subjective physical functioning, and the differences between patients who undergo total gastrectomy and subtotal gastrectomy are no longer valid several months after surgery. In order to further reduce the differences in QoL between patients who underwent total gastrectomy and subtotal gastrectomy, definitive preoperative informing, followed by postoperative symptomatic management, of restrictive symptoms in total gastrectomy patients is the most rational approach.

The onset of hypertrophic pyloric stenosis in the postoperative course of esophageal atresia with tracheoesophageal fistula is rarely reported. The diagnosis could be delayed due to its mimicking symptoms of other postoperative complications including gastroesophageal reflux or anastomotic stricture. We present an infant who had surgery for esophageal atresia with tracheoesophageal fistula. He had never fed since birth. The infant presented with an increased amount of orogastric tube drainage and consistently distended gastric air on simple abdominal X-ray. Abdominal ultrasonography showed hypertrophic thick pyloric muscle. The diagnosis of pyloric stenosis was confirmed d is rarely reported. The diagnosis could be delayed due to its mimicking symptoms of other postoperative complications including gastroesophageal reflux or anastomotic stricture. We present an infant who had surgery for esophageal atresia with tracheoesophageal fistula. He had never fed. The infant presented with uring surgery, After pyloromyotomy, the patient's condition improved.

Background and Objectives： Complications arising from endotracheal intubation are uncommon but, when they do occur, can be significant. Placement of an endotracheal tube frequently results in trauma to the underlying laryngeal and tracheal tissue, although the trauma is usually reversible. Occasionally, these changes can be of a more permanent nature and result in severe impairment of the airway and/or voice. It is proposed that a common factor-gastroesophageal reflux-might be responsible. This study was performed in order to develop the animal model of LPRD using rats and investigated that LPRD could produce significant damage to larynx especially vocal cords. Materials and Methods : The each four rats were used in the experiment and control study. Each was anesthetized and larynx was exposed and injured in the unilateral aritenoid. Injured site was contact with normal saline(control group) and synthetic gastric juice(experimental group). The larynx was examined after 7days in normal environment. Results : All was survived in the control group and two was survived in the experimental group. In the control group, some inflammation cells was found but in the experimental group, granulation was found. Conclusion : We developed animal model of LPRD using rat and thought LPRD may Play an important role in the development of permanent laryngeal injury.

목 적: 영유아에서 위식도 역류는 흔한 질환이며, 위식도 역류의 합병증으로 위 내용물의 폐 흡인에 의한 만성 호흡기 질환이 생길 수 있으나 이를 진단하기 위한 표준적인 검사 방법이 없다. 본 연구에서는 위식도 역류와 폐 흡인 진단 방법으로서 위식도 역류 신티그래피의 유용성을 평가하고자 하였다. 방 법: 위식도 역류로 인한 흡인 폐렴이 의심된 35명의 환아와 정상 대조군 5명을 대상으로 하였다. 모든 대상아에게 $^{99m}Tc$-tin colloid를 첨가한 우유를 수유한 후 위식도 역류 신티그래피를 시행하였다. 위식도 역류를 진단하기 위해 1시간 동안 동적 영상을 촬영하였고, 폐 흡인을 진단하기 위해 6시간과 24시간 후 지연 영상으로 정적 영상을 얻었다. 폐 흡인의 진단을 위해 육안분석과 함께 양쪽 폐에 관심 영역을 설정하여 정량 분석을 시행하였다. 흡인 지수는 관심 영역에서 배경 영역의 계수치를 뺀 값으로 정의하였다. 결 과: 35명의 환아 중 23명에서 신티그래피상 위식도 역류가 관찰되었고, 정상 대조군 5명에서는 위식도 역류가 발견되지 않았다. 환아군 35명 중 24명에게 24시간 하부 식도 pH 검사를 시행하였고, 7명에서 산성역류가 확인되었다. 신티그래피와 하부 식도 pH 검사를 동시에 받은 24명 중 8명에서 두 검사의 결과가 일치하여 두 검사는 위식도 역류의 진단에 있어 일치하지 않았다. 환아군 35명 중 16명에게 흉부 전산화 단층 촬영을 시행하여 13명의 환아에서 의존성 위치에 폐 경화가 발견되어 흡인 폐렴으로 진단하였고, 이 환아들이 신티그래피에서도 폐 흡인이 있었는지 그 일치도를 알아보았을 때, 두 검사는 폐 흡인의 진단에 있어 일치하지 않았다. 한 명의 환아에서 6시간 후 지연 영상에 우폐로 역류된 방사능이 육안적으로 관찰되었다. 대조군과 비교하였을 때, 30명(85.7%)의 환아에서 흡인 지수가 결정점인 0.3보다 높아 폐 흡인의 가능성이 높은 것으로 진단하였다. 역류군과 비 역류군을 비교하였을 때, 6시간 후 지연 영상에서 흡인 지수는 역류군에서 유의하게 높았다(p<0.05). 결 론: 위식도 역류 신티그래피는 비 침습적이고 안전한 검사로 위식도 역류의 진단에 있어서는 24시간 하부 식도 pH 검사에 비하여 부족하지만 역류로 인한 소량의 폐 흡인을 진단하는데 유용하며, 앞으로 통계학적으로 의미 있는 수의 대조군 연구가 수행된다면 폐 흡인을 확진할 수 있는 진단 기준이 나올 것으로 생각된다.
