Introduction: Gastrointestinal perforation due to foreign body intake is rare and often secondary to unintentional intake; hence, a misdiagnosis is likely. Herein, we report a case of perforation of the ileum due to fish bone. Case presentation: A 57-year-old woman presented with right lower abdominal pain. She did not provide any information about having a history of swallowing foreign bodies. Surgery for uterine fibroids and subtotal gastrectomy was performed 6 years ago. Diagnosis: Laboratory tests and imaging examination showed normal results. During laparotomy, a fish bone was found at the end of the ileum. Two senior radiologists re-evaluated the computed tomography scan, and confirmed the presence of the suspected foreign body. Interventions: Partial intestinal resection and manual ileum end anastomosis were performed. Outcomes: The patient recovered well after surgery and recalled that she had eaten fish the night before experiencing abdominal pain. Conclusion: An accurate diagnosis of complications due to fish bone intake, often secondary to the unintentional intake, is quite challenging. Detailed history-taking about the patient's diet and eating habits is therefore important. Clinical manifestations are mainly determined by the location of perforation, which typically occurs at the junction of the ileum and rectal sigmoid colon. Imaging examination and surgery are often used for definite diagnosis.
The present study examined kinetics of apoptosis and expression of apoptosis-related proteins Bcl-2, Bax, and caspase-3 in the CA3 hippocampus cells after diffuse brain injury (DBI) induced experimentally in rats. Percentage of apoptotic cells and expressions of above proteins were examined by flow cytometry and immunohistochemistry. Substantial neuronal apoptosis was documented in the CA3 hippocampus cells after DBI (22.26 ± 2.97 % at 72 h after DBI vs. 2.92 ± 0.88 % in sham-operated animals). Expression of Bc1-2 decreased, while expression of Bax and caspase-3 increased after DBI, with caspase-3 expression peaking after that of Bax (72 vs. 48 h, respectively). Further, the Bc1-2/Bax expression ratio decreased prior to increase of caspase-3 expression. In conclusion, cell apoptosis and altered expressions of Bcl-2, Bax, and caspase-3 are present in the CA3 region of hippocampus after experimental DBI. Changes in the Bc1-2/Bax expression ratio may facilitate activation of caspase-3 and aggravate neuronal apoptosis after brain injury.
Background Robot-assisted laparoscopic transverse colon tumor surgery requires precise tumor localization. The purpose of this study was to evaluate the safety and efficacy of nano-carbon and titanium clip combination labeling methods in robot-assisted transverse colon tumor surgery. Methods From January 2018 to January 2019, the clinical data of 16 patients who come from FuZhou, China underwent preoperative nano-carbon and titanium clip combined with robot-assisted laparoscopic transverse colon cancer surgery were retrospectively analyzed. Results Of the 16 patients, no signs of abdominal pain, fever, or diarrhea were observed after colonoscopy. Two titanium clips were seen on all of the 16 patients' abdominal plain films. Nano-carbon staining sites were observed during the operation, and no staining disappeared or abdominal cavity contamination. All patients underwent R0 resection. The average number of lymph nodes harvsted was 18.23 ± 5.04 (range, 9–32). The average time to locate the lesion under the laparoscopic was 3.03 ± 1.26 min (range, 1–6 min), and the average operation time was 321.43 ± 49.23 min (range, 240–400 min). All were consistent with the surgical plan, and there was no intraoperative change of surgical procedure or conversion to open surgery. Conclusion Preoperative colonoscopy combined with nano-carbon and titanium clip is safe and effective in robot-assisted transverse colon cancer surgery. A At the same time, the labeling method shows potential in shortening the operation time, ensuring sufficient safety margin and reducing complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
