Pancreatic injury following blunt abdominal trauma is rare, but it has high morbidity and mortality. Various treatments have been attempted, but none has yet been clearly established. The pancreatic neck transection is usually managed by using a distal pancreatectomy with or without a splenectomy. However, pancreatic insufficiency and the risk of post-splenectomy infection remain significant problems. To avoid these problems in patients with a pancreatic neck transection, one may use a pancreaticoenteric anastomosis as a treatment option, but a pancreatic fistula from the pancreaticoenteric anastomosis remains a significant cause of morbidity and mortality. Recently, several reports proposed the binding pancreaticogastrostomy to minimize the possibility of a postoperative pancreatic fistula developing after pancreatic surgery. Thus, we report a case of a traumatic pancreatic neck transection successfully treated with a binding pancreaticogastrostomy.

Improvements in the operative management of traumatic aortic transection have resulted in safe and expeditious repair. Nonetheless, multisystem injuries continue to inflict significant numbers of deaths. We have experienced a case of acute traumatic aortic transection in 41 years old male patient by a traffic accident. The transection was just distal to the origin of the left subclavian artery. We have done a synthetic graft interposition under left atrium to left femoral artery bypass with centrifugal pump. His postoperative course was smooth, and discharged without any complications.

Objectives : The evaluation of peripheral nerve injuries has traditionally relied on a clinical history, physical examination, and electrodiagnostic studies. The purpose of the present study was to examine serial magnetic resonance image(MRI) changes following acute muscle denervation under experimental conditions and to identify potential advantages and disadvantages of this use of MRI. Methods : An experimental transection of right sciatic nerve on Spargue-Dawley rats was performed. MRI was performed with T1-weighted spin-echo and STIR sequences. The imaging findings were compared with EMG in order to determine its sensitivity relative to this standard procedure. A simultaneous histopathological study provided information about the morphological basis of the imaging findings. Signal intensities were expressed as a ratio of abnormal to normal. Results : The signal intensity ratio of muscles with the STIR sequence was increased significantly at 2 weeks after sciatic nerve transection(p<0.05), although definite signal change was seen as early as 4 days postdenervation in one. EMG revealed significant denervation potential from 3 days after nerve transection. Diffuse cell atrophy was revealed hostologically at 2 weeks after transection, which was at the same time of significant signal change in MRI. Conclusion : MRI signal changes in denervated muscles secondary to nerve injury correlate with the degree of muscle atrophy on histologic examination. In addition to EMG, MRI can document the course of muscle atrophy and mesenchymal abnormalities in denervation. These results indicate that MRI can play a complementary role in the evaluation of patients with denervation.

While axons in the peripheral nerve can regenerate and lead to functional recovery to a certain extent after injury, its efficacy varies depending on the severity and duration of the injury. Here, we investigated the effects of Boyanghwano-tang (BYHOT) treatment on the regenerative responses in the sciatic nerves after prolonged transection and coaptation surgery. In mice given crush injury, axonal regeneration was completed when analyzed 1 week later and did not show any difference in regenerative reponses in the distal portion of the nerve between saline- and BYHOT-treated groups. In animal models with transection and reconnection, axonal regeneration was markedly retarded compared to animals with crush injury. Regenerating axons were extended into the reconnected distal portion of the nerve more actively in animals treated with BYHOT than saline controls. Cdc2 protein was similarly induced in nerves with crush injury and with transection and recollection, and its level was lower in BYHOT-treated animal than saline control when measured 2 weeks after nerve reconnection. These results suggest that BYHOT may be useful to promote axonal regeneration in the peripheral nerve after severe injury.

Laparoscopic distal gastrectomy has become widespread as a treatment for early gastric cancer in eastern Asia, but a standard method for setting the stomach transection line has not been established. Here we report a novel method of setting this line based on anatomical landmarks. At the start of the operation, two anatomical landmarks along the greater curvature of the stomach were marked with ink: the proximal landmark at the avascular area between the last branch of the short gastric artery and the first branch of the left gastroepiploic artery, and the distal landmark at the point of communication between the right and left gastroepiploic arteries. Just before specimen retrieval, the stomach was transected from the center of these two landmarks toward the lesser curvature. Then, about two-third of the stomach was reproducibly resected, and gastroduodenostomy was successfully performed in 26 consecutive cases. This novel method could be used as a standard technique for setting the transection line in laparoscopic distal gastrectomy.

Objective : Filum transection is one of the most commonly performed operative procedure in pediatric neurosurgery. However, the clinical and pathological features as well as the surgical indication are not well-established. This study aimed to analyze the characteristics of patients who underwent transection of the filum during the last 10 years in a single institute. Methods : A total of 82 patients underwent transection of the filum during the period. As a general rule, we performed the transection in patients who are symptomatic or have abnormality in the urologic or neuromuscular evaluations. There were exceptions as asymptomatic patients who only fit the definition of thickened filum (width greater than 2.0 mm or conus level below L3 vertebral body) were operated by parent's wish or surgeon's preference according to radiological findings, etc. Results : Seventy-six out of 82 patients had fibrous tissue in the pathologic specimen of filum. Interestingly, patients who had glial cells were more correlated with no preoperative syrinx, and no progression of syrinx even for those who did have syrinx initially. Also, larger percentage of symptomatic patients had peripheral nerve twigs than asymptomatic patients. No difference in conus level or thickness of filum was found between patients with or without preoperative syrinx. Significantly more patients with syrinx (56%) were chosen to be operated without any symptom or abnormality in study i.e., solely based on radiological findings than those without syrinx (21%). The surgical outcome for syrinx was favorable, as all but one patient had either improved or static syrinx. The exceptional case had increase in size due to the upward displacement of the proximal end of the cut filum. Conclusion : This study evaluated the pathological, clinical, radiological features of patients who underwent transection of the filum. Interesting correlations between pathological findings and clinical features were found. Excellent outcome regarding preoperative syrinx was also shown.

Traumatic aortic transection after blunt chest injury is highly lethal and has high operative mortality. Recently, the diagnostic and therapeutic method of this injury is advanced, especially in spinal cord protection during aortic cross-clamping. We have experienced two cases of traumatic aortic transection with left hemothorax after blunt chest injury, which was diagnosed in operative field. The transected aorta was primarily repaired with clamp and sew method and postoperative paraplegia had not occured. The patients were dischraged without any significant complications. We report these cases with a review of literature.

Rapid adoption of a robotic approach as a minimally invasive surgery tool has enabled surgeons to perform more complex hepatobiliary surgeries than conventional laparoscopic surgery. Although various types of liver resections have been performed robotically, parenchymal transection is challenging as commonly used instruments (Cavitron Ultrasonic Surgical Aspirator [CUSA] and Harmonic) lack articulation. Further, CUSA also requires a patient-side assistant surgeon with hepatobiliary laparoscopic skills. We present a case report of total robotic right hepatectomy for multifocal hepatocellular carcinoma in a 70-year-old male using 'Vessel Sealer' for parenchymal transection. Total operative time was 520 minutes with a blood loss of ~400 mL. There was no technical difficulty or instrument failure encountered during surgery. The patient was discharged on postoperative day five without any significant complications such as bile leak. Thus, Vessel Sealer, a fully articulating instrument intended to seal vessels and tissues up to 7 mm, can be a promising tool for parenchymal transection in a robotic surgery.
