“…Moreover, various stent-induced complications (both short-and long-term) have been reported and receive much attention, including bile duct strictures and stones, liver abscess, stent occlusion or migration, pancreatitis, intestinal obstruction, and intestinal perforation. [ 2 – 6 ] To the best of our knowledge, the long-term complication of stent-related small bowel perforation has occurred in only 2 cases: 1 case occurred 2 years after PD, and the other occurred 19 years after PD. [ 4 , 5 ] However, stent-related small bowel perforation occurring within 1 week after surgery has not been reported before.…”

Small bowel perforation caused by pancreaticojejunal anastomotic stent migration after pancreaticoduodenectomy

et al. 2020

Introduction: Pancreaticoduodenectomy (PD) has been widely applied as a standard surgical procedure to treat periampullary diseases. The placement of a pancreaticojejunal anastomotic stent is considered an effective and safe method for preventing pancreatic fistula after PD. Recently, the role of pancreaticojejunal anastomotic stents has been challenged, as gradually increasing complications have been observed. Stent-related small bowel perforation has only occurred in 2 cases as long-term complications but has not been reported to occur within 1 week after surgery. Patient concerns: Here, we report the case of a 71-year-old female patient complaining of painless jaundice who underwent PD with a pancreaticojejunal anastomotic stent for a duodenal papillary adenocarcinoma (T4N1M0). Four days after surgery, she had a sudden rise in temperature, high white blood cell count, significantly elevated C-reactive protein and 400 ml green-brown drainage fluid. Enhanced computed tomography showed hydrops abdominis. Diagnosis: Small bowel perforation caused by stent migration was considered first. Interventions: An emergency exploratory laparotomy was performed. We located the pancreaticojejunal anastomotic stent, which extended 2 cm from the small bowel, and sutured the jejunum hole after cutting away the protruding part of the stent. Outcomes: The patient recovered smoothly and was discharged on the 7th day after the second surgery. After more than 12 months of follow-up, the patient is doing well and is free of any symptoms related to the procedure. Conclusion: We caution that stent-related complications can occur when perioperative patients suffer from unexplained or sudden changes in vital signs after PD. In addition, the function of the pancreaticojejunal anastomotic stent needs to be reevaluated by future studies.

“…No significant difference was observed between the fibula implantation and tantalum rod implantation for small osteonecrosis range. Considering the damage to the donor site, fibula implantation was not effective compared with tantalum rod implantation when the osteonecrosis range is small [21,22]. …”

BackgroundThe aim of this study was to contrast the collapse values of the postoperative weight-bearing areas of different tantalum rod implant positions, fibula implantation, and core decompression model and to investigate the advantages and disadvantages of tantalum rod implantation in different ranges of osteonecrosis in comparison with other methods.Material/MethodsThe 3D finite element method was used to establish the 3D finite element model of normal upper femur, 3D finite element model after tantalum rod implantation into different positions of the upper femur in different osteonecrosis ranges, and other 3D finite element models for simulating fibula implant and core decompression.ResultsThe collapse values in the weight-bearing area of the femoral head of the tantalum rod implant model inside the osteonecrosis area, implant model in the middle of the osteonecrosis area, fibula implant model, and shortening implant model exhibited no statistically significant differences (p>0.05) when the osteonecrosis range was small (60°). The stress values on the artificial bone surface for the tantalum rod implant model inside the osteonecrosis area and the shortening implant model exhibited statistical significance (p<0.01).ConclusionsTantalum rod implantation into the osteonecrosis area can reduce the collapse values in the weight-bearing area when osteonecrosis of the femoral head (ONFH) was in a certain range, thereby obtaining better clinical effects. When ONFH was in a large range (120°), the tantalum rod implantation inside the osteonecrosis area, shortening implant or fibula implant can reduce the collapse values of the femoral head, as assessed by other methods.

Recent studies have found that triterpene acid type compounds has many effects including antiinflammatory, regulating blood sugar level, antiviral and antitumor activity. More importantly, triterpene acid type compounds has become one of the most popular topics recently because its selective toxic effects on cancer cells and harmless to normal cells at the same time. This review summarized the antitumor activity and the mechanism of triterpene acid type compounds, providing guideline for further research and development of new antitumor natural products.
