Chest injuries are classified into penetrating and blunt trauma. In Japan, penetrating thoracic trauma is infrequent, accounting for approximately 15% of all chest traumas. Most penetrating lung injuries do not require thoracotomy and are treated with a thoracic drain. We have experienced a case in which pulmonary tractotomy was useful for penetrating lung injury and a foreign body in the lung. A 30-year-old man had been operating an industrial press machine when a piece of metal flew out of it and embedded in the left thorax. Chest X-ray and CT scans revealed that metal fragments were retained in the lingular segment of the left lung and confirmed the diagnosis of penetrating lung injury due to a foreign body. A thoracotomy was performed to identify and treat the injury as well as to remove the foreign body. The entry hole of the metal piece was found in the upper left lobe, and a hard foreign body was palpable in the lingular segment. Stapled pulmonary tractotomy was successfully performed to ensure hemostasis and remove the foreign body. The patient had a good postoperative course and was discharged from our hospital without any complications on the 23 rd POD. Our experience suggests that pulmonary tractotomy is a useful technique for penetrating lung injury caused by a metal fragment.
Although afferent loop syndrome associated with gastric cancer often requires surgical treatment, it remains unclear whether invasive procedures are appropriate for terminal cancer patients. Case : A 57-year-old man had undergone Roux-en Y reconstruction for distal gastrectomy. Multiple peritoneal dissemination nodules were observed and the histopathological diagnosis was poorly differentiated Stage Ⅳ adenocarcinoma. During postoperative chemotherapy, the patient developed a complicated malignant bowel obstruction. A segmental resection of small intestine with a concomitant colostomy did not improve the symptoms ; therefore, the treatment goal was shifted to palliative care for better quality of life. However, stiffness and pain in the lower back with high fever occurred subsequently. As a blood test and abdominal computed tomography (CT) indicated afferent loop syndrome, we performed a percutaneous transhepatic biliary drainage. A catheter tip was also successfully inserted into the duodenum to reduce the pressure of the afferent loop. Subsequently, the back pain improved. The patient was discharged from hospital and began to receive home care services. Conclusion : Our experience suggests that decompression of afferent loop syndrome through percutaneous transhepatic biliary drainage is a promising option for the treatment of afferent loop obstruction due to peritoneal dissemination, even in terminal patients. Key words:afferent loop obstruction,percutaneous transhepatic biliary drainage,peritoneal dissemination
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.
