RESUMO

BACKGROUND: Gastric gastrinoma and spontaneous tumor regression are both very rarely encountered. We report the first case of spontaneous regression of gastric gastrinoma. CASE SUMMARY: A 37-year-old man with a 9-year history of chronic abdominal pain was referred for evaluation of an 8 cm mass in the lesser omentum discovered incidentally on abdominal computed tomography. The tumor was diagnosed as grade 2 neuroendocrine neoplasm (NEN) on endoscopic ultrasound-guided fine-needle aspiration. Screening esophagogastroduodenoscopy revealed a 7 mm red polypoid lesion with central depression in the gastric antrum, also confirmed to be a grade 2 NEN. Laparoscopic removal of the abdominal mass confirmed it to be a metastatic gastrinoma lesion. The gastric lesion was subsequently diagnosed as primary gastric gastrinoma. Three months later, the gastric lesion had disappeared without treatment. The patient remains symptom-free with normal fasting serum gastrin and no recurrence of gastrinoma during 36 mo of follow-up. CONCLUSION: Gastric gastrinoma may arise as a polypoid lesion in the gastric antrum. Spontaneous regression can rarely occur after biopsy.

RESUMO

Introduction: An 80-year-old woman presented to the emergency department with severe right-sided abdominal pain that had started after her last meal. Physical examination revealed fever (38.6°C) and rebound tenderness in the right upper quadrant of the abdomen. The laboratory studies showed a leucocyte count of 11.3×109/L (normal, 3.7-8.0×109/L) and a C-reactive protein level of 2.34 mg/dL (normal, <0.03 mg/dL). There were no other significant findings. A CT scan of the abdomen with contrast revealed retroperitoneal air around a duodenal diverticulum (figures 1 and 2).Figure 1Computed tomography scan of the abdomen with contrast (coronal section). A diverticulum in the second portion of the duodenum (arrow) and retroperitoneal air (asterisk) are shown.Figure 2Computed tomography scan of the abdomen with contrast (axial section). The area with retroperitoneal air (asterisk) is marked. QUESTION: What is the most likely diagnosis and the cause underlying the condition?

RESUMO

Objective In the management of patients with suspected acute drug poisoning, a screening test using the patient's urine is usually performed. The Triage DOA® and INSTANT-VIEW M-1® kits are two commonly used point-of-care screening kits in Japan. However, the relationship between the results of these screening kits and the blood concentration of the poisoning drug is not clear. In this study, we evaluated which kit is more useful for acute drug poisoning screening based on a comparison of their results with the results of a serum drug analysis. Methods This prospective cross-sectional study investigated all patients with acute drug poisoning admitted to a general hospital in Tokyo, Japan, over a nine-month period. The Triage DOA® and INSTANT-VIEW M-1® screening kits were used, and a qualitative serum analysis was conducted simultaneously in all cases. We compared the kits for use in screening patients with acute drug poisoning and evaluated the utility of the kits. Results For the 117 patients enrolled in this study, the 2 kits showed different sensitivities to benzodiazepines (Triage®, 78.6%; INSTANT-VIEW®, 90.5%). Both kits showed high sensitivity to barbiturates (Triage®, 87.0%; INSTANT-VIEW®, 91.3%) but low sensitivity to tricyclic antidepressants (Triage®, 25.0%; INSTANT-VIEW®, 45.8%). Conclusion Because the sensitivity varies depending on the kind of drug, it is difficult to discuss the superiority of these kits. However, this study compared the results of two types of urinary drug screening kits with the results of qualitative analysis of drugs in serum as a gold standard, providing important reference data.

RESUMO

INTRODUCTION: The aim of this study was to introduce and examine a modified mechanical end-to-side esophagogastrostomy method ("reverse-Tornado" anastomosis) in laparoscopy-assisted proximal gastrectomy. METHODS: Five patients with gastric cancer who underwent laparoscopy-assisted proximal gastrectomy were analyzed retrospectively. Esophagogastrostomy in the anterior wall was performed in three patients, and esophagogastrostomy in the posterior wall was performed in two patients. Clinicopathological features, operative outcomes (operative time, operative blood loss), and postoperative outcomes (complications, postoperative hospital stay, reflux esophagitis) were evaluated. RESULTS: Operative time was normal (278 min). There was no marked operative blood loss, postoperative complications, prolonged hospital stay, or reflux esophagitis. CONCLUSION: Esophagogastrostomy was completed in a normal time with reverse-Tornado anastomosis. This method can be safe and can enable good postoperative quality of life.

RESUMO

INTRODUCTION: There are several techniques for creation of a neovagina in male-to-female reassignment surgery. Although vaginoplasty with the sigmoid colon is not a common procedure, it is becoming more common. Perforation of the recto-sigmoid neovagina after sex reassignment surgery is very rare. We hereby report a case of perforation of the neovagina that presented as acute peritonitis, with a massive abscess in the intra-abdominal cavity. CASE PRESENTATION: This case report describes a 33-year-old Asian woman presenting with mild persistent abdominal pain, nausea, and vomiting who had undergone male-to-female sex reassignment surgery four years prior. Physical examination revealed mild abdominal pain without rebound tenderness. An abdominal computed tomography scan showed a massive abscess that occupied a significant portion of the intra-abdominal cavity. Perforation of the neovagina was confirmed by exploratory laparotomy and surgical drainage with primary closure was performed without any complications. CONCLUSION: This is a rare case involving perforation of the neovagina that was successfully treated with surgical intervention. This case emphasizes the importance of taking a detailed medical history and to make physicians and patients aware that bowel vaginoplasty can result in a weak vagina.
