Abstract
PURPOSE To compare the characteristics of reimplantation (RI) using grafts with sinuses and remodeling (RM) with/without external suture annuloplasty using a pulsatile flow simulator. METHODS Porcine aortic roots were obtained from an abattoir, and six models of RM and RI with sinuses were prepared. External suture annuloplasty (ESA) was performed in the RM models to decrease the root diameter to 22 mm (RM-AP22) and 18 mm (RM-AP18). Valve models were tested at mean pulsatile flow and aortic pressure of 5.0 L/min and 120/80 (100) mmHg, respectively, at 70 beats/min. The forward flow, regurgitation, leakage, backflow rates, valve-closing time, and mean and peak pressure gradient (p-PG) were evaluated. Root configurations were examined using micro-computed tomography (micro-CT). RESULTS The backflow rate was larger in the RM models than in the RI models (RI: 8.56% ± 0.38% vs. RM: 12.64% ± 0.79%; p < 0.01). The RM-AP and RI models were comparable in terms of the forward flow, regurgitation, backflow rates, p-PG, and valve-closing time. The analysis using a micro-CT showed a larger dilatation of the sinus of the Valsalva in the RM groups than in the RI group (Valsalva: RI, 26.55 ± 0.40 mm vs. RM-AP22, 31.22 ± 0.55 mm [p < 0.05]; RM-AP18, 31.05 ± 0.85 mm [p < 0.05]). CONCLUSIONS RM with ESA and RI with neo-sinuses showed comparable hemodynamics. ESA to RM reduced regurgitation.

Abstract
INTRODUCTION Tamai zone 1 replantation poses a challenge due to the very small size of the vascular structures; often there is no vein for anastomosis. Replantation may have to be done with only an arterial anastomosis. In our study, we aimed to evaluate the success of replantation by combining external bleeding and hyperbaric oxygen treatment (HBOT) in Tamai zone 1 replantation. METHODS Between January 2017 and October 2021, 17 finger replantation patients who underwent artery-only anastomosis due to Tamai zone 1 amputation received 20 sessions of HBOT with external bleeding after the 24th postoperative hour. Finger viability was assessed at the end of treatment. A retrospective review of outcomes was performed. RESULTS Seventeen clean-cut finger amputation patients were operated on under digital block anaesthesia with a finger tourniquet. No blood transfusion was required. In one patient, complete necrosis developed and stump closure was performed. Partial necrosis was observed in three patients and healed secondarily. Replantation in the remaining patients was successful. CONCLUSIONS Vein anastomosis is not always possible in fingertip replantation. In Tamai zone 1 replantation with arteryonly anastomosis, post-operative HBOT with induced external bleeding appeared to shortened the hospital stay and was associated with a high proportion of successful outcomes.

Abstract
Objective:To summarize the clinical characteristics of children undergoing surgery of cochlear reimplantation, focus on various problems and management in cochlear reimplantation, in order to avoid related problems in surgery of cochlear reimplantation and the initial implantation. Methods:A total of 32 children who underwent cochlear reimplantation in Peking University Third Hospital from July 2018 to July 2022 were retrospectively analyzed, and the duration from the initial implantation was from 1 year to 8 years. The cochlear implant mapping was performed 4 weeks after the operation, and the auditory performance was evaluated. Results:Special intraoperative issues included 32 cases with bone and soft tissue hyperplasia at various sites(2 cases with obvious bone hyperplasia in cochlear window, 1 case with obvious bone hyperplasia in subperiosteal tunnel of wire), 5 cases with bone defects in important structures(including the posterior wall of the external auditory canal, the facial nerve canal, and the subperiosteal pocker of the receiver-stimulator), 1 case with cholesteatoma, 4 cases with other lesions or foreign bodies, 4 cases with abnormal position of the electrodes(migration or reversal). All operations were successfully completed without complications. Postoperative recoveries were smooth. Conclusion:In the initial cochlear implantation, attention should be paid to retain residual hearing as much as possible, fully consider the possibility of postoperative bone hyperplasia, avoid large amounts of non-absorbable adhesive materials, avoid bone defects in important structures(such as facial nerve canal or posterior wall of the external auditory canal), pay attention to the depth and orientation of electrode implantation. The possibility of "hidden injury" mentioned above should be fully considered in surgery of cochlear reimplantation to avoid new injury or complication.

Abstract
OBJECTIVES Our aim was to evaluate the risk of concomitant aortic root replacement during frozen elephant trunk (FET) total arch replacement. METHODS Between 03/2013 and 02/2021, 303 patients underwent aortic arch replacement using the FET technique. Patient characteristics, intra- and postoperative data were compared between patients with (n = 50) and without (n = 253) concomitant aortic root replacement (implantation of a valved conduit or using the reimplantation valve sparing technique) after propensity score matching. RESULTS After propensity score matching there were no statistically significant differences in preoperative characteristics including the underlying pathology. There was no statistically significant difference regarding arterial inflow-cannulation or concomitant cardiac procedures, while cardiopulmonary bypass (p < 0.001) and aortic cross-clamp (p < 0.001) times were significantly longer in the root replacement group. Postoperative outcome was similar between the groups and there were no proximal reoperations in the root replacement group during follow-up. Root replacement was not predictive for mortality (p = 0.133, odds ratio: 0.291) in our Cox regression model. There was no statistically significant difference in overall survival (log rank: p = 0.062). CONCLUSIONS Concomitant FET implantation and aortic root replacement prolongs operative times, but does not influence postoperative outcomes or increase operative risk in an experienced high-volume centre. The FET procedure did not appear to be a contraindication for concomitant aortic root replacement even in patients with borderline indications for aortic root replacement.

Abstract
INTRODUCTION It is often questioned whether to perform replantation or revision amputation for amputation injuries in elderly patients and smokers. According to the current indication criteria, neither old age nor smoking in the absence of other risk factors are considered to be risk factors for replantation failure. However, many microsurgeons still may make the decision not to perform digital replantation based solely on these factors. MATERIAL AND METHODS In order to evaluate the influence of both factors, we provided univariate and multivariate analyses of patients who underwent replantation at our centre during a 10-year period. We divided patients in two groups according to age (< and ≥ 60 years) and smoking status. RESULTS In the univariate analysis, there were no differences in immediate results between the two age groups. In the multivariate analysis, no statistical difference was found in neither long-term nor short-term results between the two age groups and between smokers and non-smokers. CONCLUSION Smoking and age should not be considered the only risk factors when deciding whether to perform digital replantation.

Abstract
OBJECTIVES In terms of cochlear reimplantation, there is no consensus on the definition, range, or calculation formulation for the reimplantation rate. This study aims to put forward a relatively standardized and more explicit definition based on a literature review, calculate the rate of cochlear reimplantation, and examine the classification and distribution of the reimplantation causes. DESIGN A systematic review and retrospective study. A relatively clearer definition was used in this study: cochlear reimplantation is the implantation of new electrodes to reconstruct the auditory path, necessitated by the failure or abandonment of the initial implant. Seven English and Chinese databases were systematically searched for studies published before July 23, 2021 regarding patients who accepted cochlear reimplantation. Two researchers independently applied the inclusion and exclusion criteria to select studies and complete data extraction. As the effect size, the reimplantation rate was extracted and synthesized using a random-effects model, and subgroup and sensitivity analyses were performed to reduce heterogeneity. In addition, a retrospective study analyzed data on cochlear reimplantation in a tertiary hospital from April 1999 to August 2021. Kaplan-Meier survival analysis and the log-rank test were adopted to analyze the survival times of cochlear implants and compare them among different subgroups. RESULTS A total of 144 articles were included, with 85,851 initial cochlear implantations and 4276 cochlear reimplantations. The pooled rate of cochlear reimplantation was 4.7% [95% CI (4.2% to 5.1%)] in 1989 to 2021, 6.8% [95% CI (4.5% to 9.2%)] before 2000, and 3.2% [95% CI (2.7% to 3.7%)] after 2000 ( P =0.003). Device failures accounted for the largest proportion of reimplantation (67.6% [95% CI (64.0% to 71.3%)], followed by medical reasons (28.9% [95% CI (25.7% to 32.0%)]). From April 1999 to August 2021, 1775 cochlear implants were performed in West China Hospital (1718 initial implantations and 57 reimplantations; reimplantation rate 3.3%). In total, 45 reimplantations (78.9%) were caused by device failure, 10 (17.5%) due to medical reasons, and 2 (3.5%) from unknown reasons. There was no difference in the survival time of implants between adults and children ( P = 0.558), while there existed a significant difference between patients receiving implants from different manufacturers ( P < 0.001). CONCLUSIONS The cochlear reimplantation rate was relatively high, and more attention should be paid to formulating a standard definition, calculation formula, and effect assessment of cochlear reimplantation. It is necessary to establish a sound mechanism for long-term follow-up and rigorously conduct longitudinal cohort studies.

Abstract
To investigate mortality and reoperation rates following limited distal repair after acute type A aortic dissection (ATAAD) at a single medium volume institution. We analyzed all patients that underwent limited distal repair (ascending aortic or hemiarch replacement) following ATAAD between January 1998 and April 2020 at our institution. During the study period, 489 patients underwent ATAAD surgery, of which 457 (94%) underwent limited distal repair with a 30-day mortality of 12.9%. Among 30-day survivors, late follow-up was 97.7% complete with a mean follow-up of 6.0 ± 5.5 years. In all, 50 patients (11%) required a reoperation during the study period at a mean of 3.4 ± 3.4 years after initial repair, with a 30-day mortality of 12%. An aortic reoperation was required in 4.1 (2.0-6.1)%, 10.3 (7.1-13.6)%, 15.1 (10.9-19.4)%, and 18.0 (13.0-22.9)% of patients at 1, 5, 10, and 15 years. A distal reoperation was required in 3.0 (1.2-4.7)%, 8.0 (5.1-10.9)%, 10.3 (6.8-13.8)%, and 12.4 (8.2-16.5)% of patients and 4.4 (2.3-6.4)%, 10.4 (7.1-13.7)%, 13.9 (9.8-18.0)%, and 16.9 (12.0-21.9)% of patents had a distal event at 1, 5, 10, and 15 years, respectively. Limited distal repair with an ascending aortic or hemiarch replacement was associated with acceptable survival and rates of reoperations and distal events. Limited distal repair is a safe and feasible standard approach to ATAAD surgery at a medium-volume center.

Abstract
BACKGROUND Ectopic replantation and regeneration of splenic tissue fragments following splenic trauma or splenectomy is known as replantation of splenic tissue. It typically takes place in the abdominal cavity, however, splenic tissue replantation in the liver is extremely rare and difficult to diagnose. It is often misdiagnosed as a liver tumor and removed. CASE PRESENTATION We present the case of a patient with a history of traumatic splenectomy 15 years prior to the replantation of splenic tissue in the liver. A 4 cm mass in the liver was found during the most recent physical examination, and a computed tomography scan indicated the possibility of a malignant tumor. The tumor was then removed using fluorescence laparoscopy. CONCLUSION There is a possibility of intrahepatic replantation of splenic tissue in patients who have had a splenectomy in the past, have recently discovered an intrahepatic space-occupying lesion, and do not have any high-risk factors for liver cancer. Unnecessary surgery can be avoided if 99mTc-labeled red blood cells imaging using mass puncture or radionuclide examination provides a clear preoperative diagnosis. Globally, there are no reports of the use of fluorescence laparoscopy in resecting replanted splenic tissue in the liver. Specifically, in the current case, there was no indocyanine green uptake in the mass, and only a small amount was found in the normally functioning liver tissue surrounding the tumor.

Abstract
In this video tutorial, we demonstrate that minimally invasive cardiac surgery and all its benefits can be applied even to complex, multiple cardiac procedures. We present a 71-year-old patient with severely obstructive hypertrophic cardiomyopathy, moderate mitral regurgitation for systolic anterior motion of the mitral valve, moderate aortic stenosis and regurgitation and atrial fibrillation. We performed a mitroaortic valve replacement, transmitral and transaortic septal myectomy and left atrial appendage closure through a minimally invasive approach (right anterolateral minithoracotomy). After establishing peripheric cardiopulmonary bypass, aortic cross-clamping and a left atrium opening, the anterior mitral leaflet was incised circumferentially at its insertion on the annulus to allow an optimal transmitral myectomy. Subsequently, mitral valve removal was completed, and a bioprosthesis was implanted. After closure of the left atrium, the left atrial appendage was closed using a 40-mm device (Atriclip). The aorta was then opened, the aortic valve was excised and a transaortic septal myectomy was completed. Finally, a sutureless aortic bioprosthesis was implanted. Postoperative transoesophageal and transthoracic surgery demonstrated a residual left ventricular outflow tract gradient of 14 mmHg and the correct performance of both biological prostheses. Minimally invasive heart surgery can be offered even to patients requiring complex and multiple procedures, including septal myectomy. Combining the benefits of the operation with those of a minimally invasive approach may optimize postoperative and long-term surgical outcomes.

Abstract
Fourth-generation bypass techniques are novel constructs that may be useful when standard bypass methods fail.1-3 They involve the use of an unconventional (i.e., intraluminal) suturing technique (type 4A) or vascular orientation (type 4B).4 We report the use of a type 4B fourth-generation reimplantation bypass for treatment of a recurrent middle cerebral artery (MCA) aneurysm. A woman in her mid-60s presented with recurrence of a previously treated unruptured MCA aneurysm. Her aneurysm was partially coiled, and recurrence developed at the base of the coil mass. Informed consent was obtained from the patient. The MCA bifurcation was exposed with a pterional-transsylvian approach (Video 1). The aneurysm fundus was mobilized to visualize the origin at the bifurcation between the middle and frontal trunk of the MCA. Clip reconstruction was attempted via a "picket-fence" technique.5 Indocyanine green videoangiography revealed occlusion of the middle trunk. The middle trunk was transected and reimplanted to the frontal trunk in end-side fashion, with intraluminal suturing (type 4A bypass). Indocyanine green videoangiography showed no flow because of endothelial damage from the endovascular therapy. The middle trunk was transected off the frontal trunk and diverted to the temporal trunk, where a type 4B side-to-side reimplantation bypass was performed using a longer arteriotomy to maximize the anastomotic area. Patency and aneurysm occlusion were confirmed with Yellow 560 fluorescence. The patient tolerated the procedure well, and no postoperative neurologic deficits were noted. The fourth-generation bypass concepts allow the surgeon to conceive atypical constructs, which are especially useful for troubleshooting challenging revascularization scenarios.3.

Abstract
A standard surgical treatment of distal ureteric defects is represented by the ureteroneocystostomy-ureteric reimplantation. However, the procedure involves an anatomical alteration of the ureterovesical (neo)junction that often hinders the retrograde catheterisation of the reimplanted ureter.We describe a case of antegrade ureterolithotripsy (AULT) in a psoas-hitch reimplanted ureter. A woman with severe left hydronephrosis supported by a subcentimetric proximal ureteral stone in a psoas-hitch reimplanted ureter was referred to our unit. Retrograde ureteroscopy was unsuccessful due to impossibility in incannulating the ureteral neo-orifice. Following the placement of a percutaneous nephrostomy, percutaneous AULT through ureteral sheath was successfully performed with complete treatment of the stone.AULT may represent a viable alternative in the management of ureteral stones when the upper urinary tract is not amenable to retrograde ureteroscopy. In experienced hands, the procedure is straightforward and may avoid the adoption of transabdominal approaches.

Abstract
We report a novel use of transcatheter aortic valve replacement (TAVR) for valve-in-valve tricuspid valve replacement. A man in his 50s with prohibitive risks for surgical intervention underwent this procedure to improve severe, symptomatic tricuspid stenosis. Though current literature is limited to case reports, the Valve-in-Valve International Database (VIVID) reports similar mortality rates between surgical and transcutaneous replacement. As a novel, off-label procedure, there is limited operator experience. Nonetheless, in non-operative or high-risk patients, similar outcomes are noted in between transcatheter tricuspid valve replacement and surgical replacement. This registry sets the framework for further studies with the possibility of observing outcomes as operator experience increases, while highlighting the feasibility of the procedure.

Abstract
Importance Recent evidence suggests that select delayed replantation may not adversely affect digit survival; however, whether surgical timing (overnight or daytime) is associated with digit replantation outcomes is unknown. Objective To assess whether digit survival, complication rate, and duration of surgery are associated with time of replantation. Design, Setting, and Participants This retrospective case series study included all replantations performed at a single tertiary referral academic center between January 1, 2000, and August 1, 2021. Data were analyzed between October 2, 2021, and January 1, 2022. Four daytime surgery intervals were selected based on literature review. Daytime replantations started within the intervals whereas overnight replantations began outside the intervals. For each case, the procedure difficulty score and the attending surgeon expertise score were calculated. Logistic and linear regressions adjusting for confounders including procedure difficulty score and expertise score were used to assess surgical timing and outcomes. Participants were adults (aged ≥18 years) undergoing digit replantations between January 2000 and August 2021 with at least 1-month follow-up. Replantation was defined as the reattachment of a completely amputated digit that necessitated anastomosis of both artery and vein. Exposures Daytime or overnight digit replantation. Main Outcomes and Measures Viable replanted digit at 1-month follow-up, number of complications, and duration of surgery. Results A total of 98 patients (mean [SD] age, 39.5 [15.3] years; 136 [93%] men) and 147 digits met inclusion criteria. Overall success rate was 55%. Between 4 pm and 7 am, overnight replantations were associated with 0.4 fewer complications (β, -0.4; 95% CI, -0.8 to -0.1) and 90.7 minutes shorter operative time (β, -90.7; 95% CI, -173.6 to -7.7). A 1-point increase in surgeon expertise score was associated with 1.7 times increased odds of replantation success for all intervals (adjusted odds ratio, 1.7; 95% CI, 1.2 to 2.4; P = .002). There were no differences in digit survival by surgical time. Conclusions and Relevance In this case series study of digit replantations, time of operation was not associated with replantation success. Overnight replantation was associated with fewer complications and shorter duration of surgery compared with daytime surgery. Results of this study suggest that overnight replantations may be performed with outcomes comparable to daytime replantations at a tertiary care academic center.

Abstract
BACKGROUND In addition to the surgical demands of hip revision arthroplasty, the reimbursement of the different types of interventions represents a major economic challenge for orthopaedic hospitals. With complex revision endoprostheses such as, for example, modular systems or custom-made implants, the flat-rate DRG is usually not sufficient to cover the costs generated and assure sufficient revenue. TREND In Germany, the reimbursement of various replacement interventions in hip revision surgery has been differentiated and reduced in recent years and mostly not in favour of orthopaedic surgeons. Recently, the isolated cup exchange was substantially downgraded from the significantly better rated DRG I46B to the clearly lower rated DRG I47A. Isolated stem exchanges or complete exchanges of the entire endoprosthesis are sometimes only economically affordable for hospitals with supportive reimbursement by means of additional fees. An additional burden for hospitals in recent years has been the repeated deletion of additional OPS codes by insurance companies, which has led to the triggering of an additional fee. CONCLUSION In summary, hip revision arthroplasty is an economically difficult terrain, in which cost coverage with appropriate reimbursement can only be achieved under the prerequisite of high case numbers, great experience and negotiation of adequate additional fees.

Abstract
OBJECTIVES To investigate the combined effect of changing pulse shape and grounding configuration to manage facial nerve stimulation (FNS) in cochlear implant (CI) recipients. PATIENTS Three adult CI recipients with severe FNS were offered a replacement implant when standard stimulation strategies and programming adjustments did not resolve symptoms. Our hypothesis was that the facial nerve was less likely to be activated when using anodic pulses with "mixed-mode" intra-cochlear and extra-cochlear current return. INTERVENTION All patients were reimplanted with an implant that uses a pseudo-monophasic anodic pulse shape, with mixed-mode grounding (stimulus mixed-mode anodic)-the Neuro Zti CI (Oticon Medical). This device also allows measurements of neural function and loudness with monopolar, symmetric biphasic pulses (stimulus MB), the clinical standard used by most CIs as a comparison. MAIN OUTCOME MEASURES The combined effect of pulse shape and grounding configuration on FNS was monitored during surgery. Following CI activation, FNS symptoms and performance with the Neuro Zti implant were compared with outcomes before reimplantation. RESULTS FNS could only be recorded using stimulus MB for all patients. In clinical use, all patients reported reduced FNS and showed an improvement in Bamford-Kowal-Bench sentences recognition compared with immediately before reimplantation. Bamford-Kowal-Bench scores with a male speaker were lower compared with measurements taken before the onset of severe FNS for patients 1 and 2. CONCLUSIONS In patients where CI auditory performance was severely limited by FNS, charge-balanced pseudo-monophasic stimulation mode with a mixed-mode grounding configuration limited FNS and improved loudness percept compared with standard biphasic stimulation with monopolar grounding.

Abstract
Amputation of the penis is a rare and devastating injury. The etiologies vary from accidental, self-inflicted to attacks due to sexual jealousy and revenge. In the present era of microvascular surgery, replantation is the standard care. However, replantation of the penis comes with its own set of difficulties and complications. Knowledge of the anatomy and prior knowledge of the possible complications makes the surgeon aware of the course of events after a replantation. It helps in devising strategies to overcome these challenges methodically. We present a case of penile replant with the complications that we encountered, and the measures are taken to counter them on our way to a successful outcome.

Int J Surg 2022; 98:106214. [PMID: 34995808 DOI: 10.1016/j.ijsu.2021.106214] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Revised: 12/11/2021] [Accepted: 12/18/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND Microsurgical anastomosis is technically difficult especially for less-experienced surgeons. Traditionally, surgeons in training could only accomplish these surgeries under intensive guiding and supervision from senior surgeons. This study presents and characterises a new method for microsurgical trainees to objectively evaluating the quality of vascular anastomosis intraoperatively. MATERIALS AND METHODS We conducted a prospective study to determine the utility of patency test of vascular anastomosis with assistance of high-speed video recording (PTHVR) to evaluate the quality of vascular anastomosis during microsurgery. To determine whether the use of PTHVR outperformed traditional supervision from senior surgeons (historical control), we compared the outcomes of microsurgeries including free flap transfer and replantation between the two groups. RESULTS A total of 211 patients were enrolled, of which 98 underwent surgery under traditional supervision and 113 underwent surgery with PTHVR. Of the 211 patients, 102 underwent digit replantation (48%), 22 underwent limb replantation (10%), and 87 underwent free flap transfer (42%). There was no statistical difference between the two groups in age, gender, BMI, pre-existing comorbidities, smoking status, alcohol consumption, and duration of surgery. Use of PTHVR as an intraoperative guide significantly decreased the rate of re-exploration surgeries (PTHVR, 8.0% [9/113]; control, 23.5% [23/98]; P = 0.002) and replantation/free flap failures (PTHVR, 8.8% [10/113]; control, 19.4% [19/98]; P = 0.029) compared with historical control under traditional supervision. CONCLUSIONS PTHVR is a useful tool for improving the success rate of microsurgery for less-experienced surgeons when compared with traditional supervision mode.
