This study aimed to compare the success rates of fingertip replantation with and without venous anastomosis.
This retrospective study included 132 patients with 148 fingertip injuries who had ...undergone fingertip replantation (Ishikawa's classification I‒IV) between 2003 and 2020 at our hospital. Among them, 117 and 15 were men and women respectively, and their mean age was 43 years. There were 53, 44, and 51 fingertips with Ishikawa subzone II, III, and IV amputations respectively, and no cases were classified as Ishikawa subzone I. Venous anastomosis was performed on 64 fingertips (group A). This was not possible in the remaining 84 fingertips; thus, an external bleeding method was used (group B). Our external bleeding protocol consisted of 4-hourly skin pricks of the distal pulp with a 23-gauge needle for the first 5 days. The analyses included survival rates, hemoglobin levels (Hb), and blood transfusions administered.
The overall survival rate was 90.5% (134 of 148). In group A, survival was achieved in 92.3%, 100%, and 94.3% of those with subzones II, III, and IV amputations, respectively. In group B, survival was achieved in 100%, 82.1%, and 62.5% of those with subzones II, III, and IV, respectively. Subzone IV in group B showed a significantly lower rate of replantation success. In groups A and B, the preoperative and 7-day postoperative Hb levels were 14.5 g/dL and 14.6 g/dL, and 11.3 g/dL, and 11.6 g/dL, respectively. In addition, blood transfusion was required for five patients (7.9%) in group A and six patients (7.9%) in group B. Thus, the Hb levels and blood transfusion administered were similar between the two groups.
Subzone IV is an important threshold for artery-only replantation. Furthermore, our external bleeding protocol is a safe and effective method.

The replantation of multiple amputated digits is a technically challenging procedure for reconstructive surgeons that requires more time than the replantation of a single digit. We evaluated the ...effect of multiple-digit replantation on the success of digital replantation.
Patients who experienced digital amputation and underwent digital replantation from January 2018 to December 2021 were studied retrospectively. Patients who experienced successful and failed replantation were compared, as were digits that survived or became necrotic after replantation. A multivariate logistic regression (MLR) analysis was performed to evaluate the independent factors of replanted digit survival.
There were 378 patients with 497 amputated digits who underwent digital replantation. Of all 378 patients, 298 underwent single-digit replantation, and the other 80 patients underwent multiple-digit replantation. A total of 83.3% of the replanted digits survived (414 of 497). Compared with patients with surviving replanted digits, significantly more patients with necrotic replanted digits underwent multiple-digit replantation (37.7% vs. 17.5%, p < 0.001). On the other hand, a digit that developed necrosis after replantation was more likely to have been involved in the replantation of three or more digits (16% vs. 29%, p = 0.005). The subsequent MLR analysis revealed that the likelihood of necrosis was 2.355 (p = 0.003) times higher in the replantation of three or more digits than in the replantation of one or two digits.
Patients who underwent multiple-digit replantation exhibited a higher incidence of necrosis in the replanted digits. In cases involving patients with multiple-digit amputation, it is crucial to prioritize and perform selective replantation based on the amputated digits.
The technique of intentional replantation can provide a second chance to save teeth that would be destined for extraction. Therefore, the present systematic review aimed primarily to estimate tooth ...survival after intentional replantation and secondarily to compare treatment outcomes in single-rooted and multi-rooted teeth. The study protocol was developed before the analysis according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Articles were electronically searched in PubMed/MEDLINE, the COCHRANE library and Google Scholar by two independent reviewers, and those that met the eligibility criteria were included. A statistical analysis using the chi-square test with a p-value of <0.05 was performed on the reported outcomes of intentional replantation. A total of 44 single-rooted replanted teeth with five failures (11.36%) and 42 multi-rooted replanted teeth with six failures (14.28%) were reported in the literature, corresponding to a survival rate of 88.64% and 85.57%, respectively. The overall survival rate for the replantation procedure was 86.7%, indicating that intentional replantation can be considered a safe therapeutic choice, with no statistically significant difference between the survival rates of single-rooted and multi-rooted replanted teeth.
Abstract Introduction Intentional replantation is an alternative to tooth extraction and prosthetic replacement when conventional endodontic treatment modalities are unfeasible or contraindicated. ...This study assessed tooth retention and healing after intentional replantation and explored predictors of these outcomes. Methods Data of intentional replantation procedures performed between March 2000 and December 2010 were collected prospectively, excluding teeth with preoperative periodontal and root defects. A cohort of 159 teeth was followed up for 0.5–12 years. Retention and healed status without complications (periapical radiolucency, external root resorption, ankylosis, signs/symptoms, probing ≥6 mm) was recorded and analyzed with Kaplan-Meier survival analysis and Cox proportional hazard regression model ( P < .05). Results Complications leading to extraction occurred in 8 of 159 teeth (5%). Kaplan-Meier survival function suggested 93% cumulative 12-year retention. Cumulative healed rates declined from 91% at 6 months to 77% at 3 years. The healed rate was significantly lower for maxillary teeth without preoperative periapical radiolucency, replanted in more than 15 minutes, and root-end filled with ProRoot MTA. Cox regression identified extraoral time ≤15 minutes as predictor of complication-free healing ( P < .04; hazard ratio, 2.767; 95% confidence interval, 1.053–7.272). Conclusions This prospective cohort study of contemporary intentional replantation suggested a cumulative 12-year retention rate of 93% and healed rate of 77% after 3 years. Healing occurred 1.7 times more frequently in teeth replanted within 15 minutes. Although most complications occurred within 1 year after replantation, follow-up should extend for at least 3 years to capture late complications.
Genital self-mutilation is a rare urologic surgical emergency that is usually encountered in patients with underlying psychiatric illness. Because of shortage of published data and variance in ...management schemes worldwide, these conditions can present a significant management dilemma.
In this case report we present this rare phenomenon, where a known schizophrenic patient presented after he amputated both of his testes and penis under the influence of command hallucination. After 15 h of the incident, macroscopic replantation of the severed genitalia was done and psychiatric evaluation and management initiated simultaneously. But the replantation failed after 9th post operative day.
Initial management of patients presenting with genital amputation should be resuscitation. The severed organ has to be washed with sterile saline and placed in “double bag”. There are multiple factors for the success of replantation, the major ones are cooling of the amputated organ and precise microsurgical replantation.
Early intervention and microscopic replantation are crucial for the successful outcome.
•Bilateral testicular and penile self- amputation is one of the rarest forms of self-amputation.•Prolonged ischemia time has detrimental effect in successful replantation of the severed organ.•If it is possible replantation of organs should bed done using microscopic surgery.

Purpose We characterize the use of pediatric open, laparoscopic and robot-assisted laparoscopic ureteral reimplantation in the United States from 2000 to 2012. Materials and Methods We used the Kids’ ...Inpatient Database to identify patients who underwent ureteral reimplantation for primary vesicoureteral reflux. Before 2009 laparoscopic ureteral reimplantion and robot-assisted laparoscopic ureteral reimplantation were referred to together as minimally invasive ureteral reimplantation. A detailed analysis of open vs robot-assisted laparoscopic ureteral reimplantation was performed for 2009 and 2012. Results A total of 14,581 ureteral reimplantations were performed. The number of ureteral reimplantations yearly decreased by 14.3%. However, the proportion of minimally invasive ureteral reimplantations increased from 0.3% to 6.3%. A total of 125 robot-assisted laparoscopic ureteral reimplantations were performed in 2012 (81.2% of minimally invasive ureteral reimplantations), representing 5.1% of all ureteral reimplantations, compared to 3.8% in 2009. In 2009 and 2012 mean ± SD patient age was 5.7 ± 3.6 years for robot-assisted laparoscopic ureteral reimplantation and 4.3 ± 3.3 years for open reimplantation (p <0.0001). Mean ± SD length of hospitalization was 1.6 ± 1.3 days for robot-assisted laparoscopic ureteral reimplantation and 2.4 ± 2.6 for open reimplantation (p <0.0001). Median charges were $22,703 for open and $32,409 for robot-assisted laparoscopic ureteral reimplantation (p <0.0001). These relationships maintained significance on multivariate analyses. On multivariate analysis robot-assisted laparoscopic ureteral reimplantation use was associated with public insurance status (p = 0.04) and geographic region outside of the southern United States (p = 0.02). Only 50 of 456 hospitals used both approaches (open and robotic), and only 6 hospitals reported 5 or more robot-assisted laparoscopic ureteral reimplantations during 2012. Conclusions Treatment of primary vesicoureteral reflux with ureteral reimplantation is decreasing. Robot-assisted laparoscopic ureteral reimplantation is becoming more prevalent but remains relatively uncommon. Length of stay is shorter for the robotic approach but the costs are higher. Nationally robot-assisted laparoscopic ureteral reimplantation appears to still be in the early phase of adoption and is clustered at a small number of hospitals.
The aim of this study was to investigate the survival rate of teeth intentionally replanted with a modern technique and to compare their cost-effectiveness with that of single-tooth implants.
Four ...databases were systematically searched for articles that met inclusion criteria published between January 1966 and February 2017. Overall survival rate of intentional replantation was determined through a meta-analysis using a random-effects model. Cost of different procedures was determined from the 2016 American Dental Association Dental Fees Survey. Cost-effectiveness analysis was performed for different treatment modalities.
Six studies met the inclusion criteria. Meta-analysis resulted in a survival rate of 89.1% (95% confidence interval, 83.8%–94.4%). Compared with a single-tooth implant, intentional replantation was more cost-effective even when custom post/core and crown are also needed.
The meta-analysis revealed a high survival rate for intentional replantation. Although the survival rate of implants is higher, intentional replantation is a more cost-effective treatment modality. Intentional replantation should be a treatment option discussed with patients, especially because an implant can still be placed if intentional replantation is unsuccessful.
•First systematic review on survival rate of teeth intentionally replanted with a modern technique and first cost-effectiveness analysis of intentionally replanted teeth.•Survival rate of intentionally replanted teeth is 89.1%.•Intentional replantation is more cost-effective than a single-tooth implant.•When nonsurgical and surgical retreatments are not possible, intentional replantation is an alternative to extraction and replacement with a single-tooth implant.
This European Society of Endodontology (ESE) position statement on surgical extrusion, intentional replantation and tooth autotransplantation represents the consensus of an expert committee, convened ...by the ESE. A narrative review in the International Endodontic Journal (Plotino et al. 2020, international Endodontic Journal, 53, 1636-52) formed the basis for the position statement. The review provided detailed information on the background, clinical procedures and the outcome of surgical extrusion, intentional replantation and tooth autotransplantation techniques. The aim of the current statement is to summarize the best available evidence on these clinical techniques to provide appropriate clinical guidance to undergraduate and postgraduate students, dental practitioners, clinical teachers and researchers. The current position statement will be updated by the ESE periodically to reflect new evidence as it becomes available to provide the most current treatment guidance for clinical practice.
Aggressive chemotherapy/radiotherapy and bone marrow transplantation can cure >90% of girls and young women affected by disorders requiring such treatment. However, the ovaries are very sensitive to ...cytotoxic drugs, especially to alkylating agents. Several options are currently available to preserve fertility in cancer patients. The present review reports the results of 60 orthotopic reimplantations of cryopreserved ovarian tissue performed by three teams, as well as 24 live births reported in the literature to date. Restoration of ovarian activity occurred in almost all cases in the three series. Among the 60 patients, eleven conceived and six of those had already delivered twelve healthy babies. In the future, we are looking to: 1) improve freezing techniques; and 2) enhance the “vascular bed” before reimplantation to increase pregnancy rates. On the other hand, cryopreservation of ovarian tissue may be combined with removal, via puncture, of small antral follicles, making it possible to freeze both ovarian tissue and isolated immature oocytes.
