We report a very rare case of surgery on gastric conduit cancer. A 67-year-old male patient underwent esophagectomy and intrathoracic esophagogastrostomy for squamous cell carcinoma of the lower thoracic esophagus 27 months ago. Upon follow-up, a gastric carcinoma at the intra-abdominal part of the gastric conduit was found on an esophagogastroduodenoscopy. We performed total gastrectomy and esophagocolonojejunostomy in the manner of Roux-en-Y anastomosis. The postoperative course was not eventful and an esophagogram on the 10th postoperative day showed no leakage or stenosis of the passage. The patient was discharged on the 17th day with no complications.

Objective: The purpose of this study was to investigate the efficacy and safety of spinal-Z, derived from Peganum harmala seeds and Dracocephalum Kotschyi Boiss leaves, in patients with esophageal and stomach adenocarcinoma, and squamous cell carcinoma of the esophagus. Methods: Sixty-one patients with malignancies of the upper gastrointestinal tract were randomly assigned to one of two groups (treatment or control) in a double-blind fashion. Six capsules of Spinal-Z were prescribed to the patients with the regimen of 600 mg/m2/day, and placebo to the control group, for six months. Results: There were no significant differences between the two groups with regard to age, sex, duration of cancer, type of cancer and family history of cancer. There were significant differences in abdominal pain, heartburn, constipation and vomiting between the two groups, following spinal-Z therapy. Evaluation of drug side effects showed no difference in cough or other respiratory symptoms, itching, headache or dizziness between the two groups, both before and after treatment. Conclusion: This study indicates that Spinal-Z is safe and efficacious in the management of patients with upper gastrointestinal tract cancers.

Cytologic diagnosis of the metastatic tumors to the thyroid is important in the management of the patients. There have been rare reports analyzing fine-needle aspiration (FNA) cytology of metastatic tumors to the thyroid. This study examines comprehensive cytologic findings of metastatic tumors to the thyroid with radiologic findings. The FNA cytology slides obtained from 12 cases with metastatic tumors of the thyroid; lung cancer (n=5), tongue and tonsil cancer (n=3), esophageal cancer (n=2), and breast cancer (n=2) were reviewed. Radiological study showed single mass with heterogeneous texture or multiple masses without calcification. Metastatic tumor was easily considered in a differential diagnosis of FNA cytology because they had peculiar cytological features which were not seen in primary thyroid tumor. The smear background varied from predominantly necrotic, bloody, and inflammatory to colloid. The aspirates exhibited a mixture of benign follicular cells and malignant cells in 6 cases. The characteristic cytoplasmic features of the tumor cells, such as keratin, mucin and melanin, were found in 9 cases. Although some cases mimic primary thyroid neoplasm, a careful examination of the cytological characteristics may help cytopathologists to recognize a metastatic tumor in the thyroid by FNA, and may help the clinicians to establish a proper treatment plan.

Objectives: The purpose of this systematic review was to evaluate the effects of herbal medicine on Chemo-Radiotherapy-induced oral mucositis. Methods: Electronic databases were used to search for studies published through 10 years until October 2022, and a randomized controlled study was conducted to evaluate efficacy of herbal medicine on chemo-radiotherapy-induced oral mucositis. Study quality was assessed using the Cochran's risk bias tool. Results: Two-hundred and three articles were initially searched, and 11 studies (head and neck cancer, breast cancer, colorectal cancer, esophageal cancer etc. undergoing radio-chemotherapy were included in analysis. The effect of herbal medicine on chemo-radiotherapy-induced oral mucositis, 9 studies reported that herbal medicine was more effective than the placebo group or conventional treatment. One study reported that the effect of the herbal compound treatment group was similar to that of the conventional herbal medicine, and one study reported that there was no difference in effect between the two herbal medicines and the group without treatment. Conclusion: This study suggests that herbal medicine effectively relieves the symptoms of chemo-radiotherapy-induced oral mucositis. However, there is limited evidence that herbal medicine may relief chemo-radiotherapy-induced oral mucositis, so further investigation is needed.

식도암으로 인한 기관지 식도 누공 환자는 음식물을 섭취하면 누공을 통하여 기관지로 음식물이 흡입되어 폐렴과 같은 합병증을 유발할 수 있다. 특히 전신쇠약이 동반되고 면역력이 저하되어 있는 식도암 환자에게는 치명적인 결과를 초래할 수 있다. 기관지 식도 누공의 내시경적 치료는 환자에게 경구 섭취를 가능하게 하고, 합병증의 발생을 예방할 수 있을 것으로 생각된다. 하지만 아직까지 장기간의 효과 지속성이나 재발에 관하여는 만족스러운 결과가 없는 실정이다. 향후 새로운 내시경 치료법의 개발 및 치료 효과에 대한 연구가 필요하다고 생각한다.

Appropriate sedation and analgesia are crucial for successful endoscopic procedures, patient safety, and satisfaction. Endoscopic resection for upper gastrointestinal tumors requires a deep sedation level because the procedure is lengthy and induces moderate to severe pain. Continuous patient consciousness assessment and vigilant vital signs monitoring are required for deep sedation. General anesthesia may unintentionally occur even during deep sedation for endoscopic tumor resection, which may cause unexpected complications, especially in high-risk patients. Previous studies have revealed that general anesthesia increases the en bloc resection rate and decreases the procedure time. Complications, such as perforation, aspiration pneumonia, and cardiopulmonary instability, including hypoxemia, hypotension, and arrhythmia, occurred more frequently in patients with sedation compared to those with general anesthesia. Therefore, general anesthesia demonstrated potential benefits in endoscopic treatment results and patient safety. General anesthesia should be considered a useful alternative for sedation in patients undergoing endoscopic gastrointestinal tumor resection. However, more high-quality prospective studies are required to determine the safety and effectiveness of general anesthesia in endoscopic upper gastrointestinal tumor resection because most studies comparing general anesthesia and sedation in these procedures have been retrospectively conducted and the results were inconsistent.

Objective: To establish the prevalence and distribution profile of esophageal squamous cell carcinomas (ESCCs) over a 22-yr period in North China. Methods: Using endoscopy for primary diagnosis and histological analysis for the further confirmation, a total of 74,854 ESCC patients aged 20-89 between January 1985 and December 2006 were investigated to analyze the epidemiological profile including prevalence rates, distribution of age-of-onset, gender and geographical area of ESCC in Luoyang, the highest incidence area of North China. Results: A total of 4092 cases of ESCC were finally diagnosed among 74,854 patients who had their first endoscopies. The prevalence among males was higher than that among females (p<0.01), resulting in an overall male:female OR of 1.2 (95%CI, 1.2-1.3). The prevalence in rural areas was higher than in urban areas (p<0.01), resulting in an overall rural:urban OR of 2.6 (95%CI, 2.4-2.9). The rural:urban ORs and the 95% CI increased continuously from 2.6, 2.3-3.0 to 2.7, 2.2-3.3, respectively, for 4 consecutive periods during the 22-yr study period. Moreover, the median age of onset among females was higher than that among males (p<0.01). For both sexes and in both areas, the prevalence rates declined and the median age of onset rose for 4 consecutive periods in the 22-yrs time frame (p<0.01). Conculsions: These data reveal the epidemiological profile of ESCC in the area of North China, and suggest that urban areas and rural people account for a growing proportion of the ESCC patients although the prevalence of ESCC significantly declined and the median age-of-onset postponed over the 22-yrs period. Moreover, the prevalence status of ESCC in rural areas also underlines the need for public health initiatives aimed at reducing risk factors of this fatal disease.

Purpose: The optimal treatment for gastroesophageal junction adenocarcinoma (GEJA) remains controversial. We evaluated the treatment patterns and outcomes of patients with locally advanced GEJA according to the histological type. Materials and Methods: We conducted a single-institution retrospective cohort study of patients with locally advanced GEJA who underwent curative-intent surgical resection between 2010 and 2020. Perioperative therapies as well as clinicopathologic, surgical, and survival data were collected. The results of endoscopy and histopathological examinations were assessed for Siewert and Lauren classifications. Results: Among the 58 patients included in this study, 44 (76%) were clinical stage III, and all received neoadjuvant therapy (72% chemoradiation, 41% chemotherapy, 14% both chemoradiation and chemotherapy). Tumor locations were evenly distributed by Siewert Classification (33% Siewert-I, 40% Siewert-II, and 28% Siewert-III). Esophagogastrectomy (EG) was performed for 47 (81%) patients and total gastrectomy (TG) for 11 (19%) patients. All TG patients received D2 lymphadenectomy compared to 10 (21%) EG patients. Histopathological examination showed the presence of 64% intestinal-type and 36% diffuse-type histology. The frequencies of diffuse-type histology were similar among Siewert groups (37% Siewert-I, 36% Siewert-II, and 33% Siewert-III). Regardless of Siewert type and compared to intestinal-type, diffuse histology was associated with increased intraabdominal recurrence rates (P=0.03) and decreased overall survival (hazard ratio, 2.33; P=0.02). With a median follow-up of 31.2 months, 29 (50%) patients had a recurrence, and the median overall survival was 50.5 months. Conclusions: Present in equal proportions among Siewert types of esophageal and gastric cancer, a diffuse-type histology was associated with high intraabdominal recurrence rates and poor survival. Histopathological evaluation should be considered in addition to anatomic location in the determination of multimodal GEJA treatment strategies.
