It is technically challenging to perform LPD with portal vein resection and reconstruction. CASE SUMMARY A 71-year-old female patient was diagnosed with distal cholangiocarcinoma. After preoperative examination and rigorous preoperative preparation, the patient underwent LPD using 3D laparoscopy on July 17, 2018. During the surgery, we found that the tumor invaded the right wall of the portal vein;thus, pancreaticoduodenectomy combined with partial portal vein wall resection was performed. The defect of the portal vein wall was approximately 2.5 cm × 1.0 cm. The hepatic ligamentum teres was excised by laparoscopy and then recanalized in vitro. Following recanalization, the hepatic ligamentum teres was cut longitudinally and then trimmed into vascular patches that were then used to reconstruct the defect of the portal vein through 3D laparoscopy. The operative time was 560 min, and intraoperative blood loss was 100 mL. The duration of the blood occlusion time was 63 min. No blood transfusion was required. The patient underwent enhanced recovery after surgery procedures after the operation. The patient was discharged on postoperative day 11. Follow-up for 6 months after discharge showed no stenosis of the portal vein and good patency of blood flow. CONCLUSION It is safe and feasible to use the hepatic ligamentum teres patch to repair portal vein in LPD. However, the long-term patency of this technique for venous reconstruction requires further investigation.展开更多

Initial examination revealed a fist-size mass at the epigastric fossa. Ultrasonography showed a hemangioma and a mosaic echoic lesion in the ventromedian with poor blood-flow signal and linear hyperechoic part inside, and a clear border to the surroundings. Dynamic computed tomography revealed a highly enhanced effect from the portal-venous phase continuing to the equilibrium phase. T1-weighted gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced image revealed a high intensity effect at the early phase that continued to the next phase. On the other hand, it contained a low intensity area by a fat suppression of that image. In addition, a T2-weighted image did not show a high intensity effect. Laparotomy was performed on the second day of hospitalization. The tumor had arisen from the ligamentum teres of the liver, and no metastasis or invasion of other organs was noted. It consisted of a lipid component of mature adipocytes and a fibrous component of deep dyeing pleomorphic or multinuclear atypical stromal cells. Immunohistochemical study of the atypical stromal cells demonstrated that they were positive for MDM2 and CDK4. A pathological diagnosis of atypical lipomatous tumor(ALT) was made, and the patient was discharged on the eighth day following the procedure. At the 6-mo follow-up dynamic CT, the patient was free of recurrence or metastasis. We experienced a patient with ALT in the ligamentum teres of the liver. This case suggests the need for a careful and detailed examination when encountering patients presenting with a mass; when neoplastic lesion is confirmed by image inspection, we should thoroughly investigate, including further image investigations and pathologic examination. The latter is the most important.展开更多

A male patient in his 70 s was diagnosed with advanced gallbladder cancer directly infiltrating the right hepatic duct(RHD), together with RSLT. Preoperative three-dimensional simulation of the liver based on multiple detector computed tomography images after cholangiography revealed ramifications of all segmental portal veins from the portal trunk and discordance of the arterial and biliary branching patterns of segment 8. Fusion analysis of the biliary architecture and segmental volumetry showed that the RHD drained segments 1 r, 5, 6, and 7. We successfully performed a modified right-sided hepatectomy sparing segment 8(i.e., resection of the RHD drainage territory), with negative surgical margins. This report is the first to describe major hepatectomy for advanced gallbladder cancer with RSLT.展开更多

Although there are only occasional reports of variations of the rotator cuff muscles, this paper reports the first combined occurrence of triple-tailed teres minor and infraspinatus muscle possessing two distinct parts, infraspinatus major and minor which are of clinical and sporting importance. Aberrant variations of rotator cuff muscles need to be brought to the knowledge of radiologists, surgeons and anatomists.展开更多

Tendon transfer surgery extended to the use for traumatic reconstructive surgery during World War I, with key surgical pioneers, including Mayer, Sterling Bunnell, Guy Pulvertaft and Joseph Boyes. In 1921, Robert Jones first described the transfer of pronator teres (PT) to the wrist extensors for irreparable radial nerve paralysis in infantile hemiplegia. Although, a detailed description of its indication and surgical outcomes were not published until 1959 and 1970 by Stelling and Meyer, and Keats, respectively. Pronator teres is often the tendon of choice for reconstructing wrist extensors, and used in a multiple of pathologies, including radial nerve palsy, cerebral palsy, and tetraplegia. Reconstruction of finger extensors are less straightforward and options include flexor carpi radialis (FCR), flexor carpi ulnaris (FCU), and flexor digitorum superficialis (FDS). Our article describes the techniques and outcomes of 25 patients that undergone pronator teres transfer. A good understanding of the pronator teres anatomical location and potential variations, aids efficient harvesting and limits unnecessary tissue dissection. Pronator teres tendon harvest is best performed through a systematic and anatomic approach.展开更多
