Objective To summarize the recent progress of cell-based approaches for promoting bone regeneration in distraction osteogenesis (DO). Methods Recent literature concerning enhancement of bone regeneration following DO using cell-based approaches was reviewed and analyzed. Results An overview of 4 different cell-based approaches was mainly provided: single cell injection, cell scaffold-based strategies/injectable tissue engineered bone, microtissue technology or cell aggregate technology, and stem cell gene therapy. Each has its advantages and disadvantages. Other methods are still in the experimental research except that compound injection of bone marrow mesechymal stem cells and platelet-rich plasma has been applied to clinical practice. Conclusion The cell-based approach is a promising strategy in the field of bone regenerative medicine. These approaches have bright future in promoting bone regeneration and reducing the treatment period in DO in the clinical application. However, well-designed preclinical studies are required to establish safe and effective guidelines for cell-based approaches to promoting bone regeneration during DO.
Objective To explore the effectiveness of tension-free herniorrhaphy with Ultrapro Plug (UPP) mesh through a femoris approach for femoral hernia repair. Methods Between March 2009 and January 2013, 123 patients (126 sides) underwent tension-free herniorrhaphy with UPP mesh through a femoris approach. There were 17 males and 106 females, aged 32-95 years (mean, 63.3 years). The locations were the left side in 48 cases, the right side in 72 cases, and both sides in 3 cases. The disease duration was 1 month to 26 years (median, 25 months). Of 123 cases, 35 cases (36 sides) were reducible and 88 cases (90 sides) were irreducible. According to American Society of Anesthesiologists (ASA) classification, 20 cases were rated as grade I, 42 cases as grade II, 56 cases as grade III, and 5 cases as grade IV. The operation time, postoperative hospitalization time, complication, recurrence, and chronic pain were recorded. Results The operation time was 7-28 minutes (mean, 14.5 minutes); postoperative hospitalization time was 2-96 hours (mean, 19.4 hours) (112 patients discharged from hospital within 24 hours). Wound dehiscence occurred in 1 case and fat liquefaction in 2 cases. A total of 119 patients (122 sides) were followed up 4-50 months (median, 18 months); no recurrence was noted. Two cases (2 sides) suffered from chronic pain after operation, whose visual analogue scale (VAS) was 20 mm and 30 mm, respectively. Conclusion Tension-free herniorrhaphy with UPP mesh through a femoris approach should be recommended because it has the advantages of simple operation, short operation time, less complication, and lower incidence of chronic pain.
ObjectiveTo observe the effect of transabdominal preperitoneal (TAPP) laparoscopic hernia repair by same-day surgery mode for patients with inguinal hernia. MethodsThe patients who underwent TAPP laparoscopic hernia repair were retrospectively collected in the Day Surgery Center of West China Tianfu Hospital from July 2022 to June 2023. All patients in this study were admitted according to the same-day surgery plan, and those who were admitted to the hospital on the same day, operated on the same day, and returned to their homes on the same day, i.e., those who did not stay in the hospital overnight (the same-day surgery plan of the West China Tianfu Hospital of Sichuan University is now basically in the range of 8∶00–20∶00, and the latest discharge is at 21∶00) were classified as the same-day surgery group; however, the patients whose special cases needed to be postponed due to the condition of their illnesses, or those who were discharged from the hospital after 21∶00 due to safety considerations because of other reasons such as postoperative observation of patients with general anesthesia for a period of less than 2–4 h, or those who had a strong desire to be admitted to the hospital overnight, and whose hospital stay was not more than 24 h, were classified as the non-same-day surgery group. The age, gender, marital status, body mass index, hernia type, surgical site, home address, intraoperative bleeding, operative time, total hospitalization cost, pain score at discharge, unplanned revisit rate within 30 d after surgery, discharge satisfaction were compared between the patients of two groups. ResultsA total of 167 patients underwent TAPP laparoscopic hernia repair were enrolled in this study, including 97 in the same-day surgery group and 70 in the non-same-day surgery group. There were no statistically significant differences in the age, gender, marital status, body mass index, hernia type, surgical site, intraoperative bleeding, operative time, and total hospitalization cost between the two groups (P>0.05). However, it was found that the patients in the non-same-day surgery group had a higher pain score at discharge and a higher proportion of home address outside Chengdu city as compared with the same-day surgery group (P=0.042, P<0.001, respectively); The satisfaction rate of all patients in this group was 100% on the 28th day after discharge, and the unplanned revisit rate within 30 d after surgery was 3.6% (6/167), although which in the same-day surgery group was slightly higher than the non-same-day surgery group, the difference was not statistically significant by Fisher test [4.1% (4/97) versus 2.9% (2/70), P=0.226]. ConclusionFrom the analysis results of this study, TAPP laparoscopic hernia repair for patients with inguinal hernia by the same-day surgery mode is safe, and it can further shorten the hospitalization time as compared with the non-same-day surgery.
