Use of a microvascular coupler device for end-to-side venous anastomosis in oral and maxillofacial reconstruction

The aim of this study was to compare the use of a microvascular coupler device (MCD) for end-to-side venous anastomosis (ETS group) and phleboplasties combined with MCD for end-to-end venous anastomosis (ETE group) in free tissue transfer for oral and maxillofacial reconstruction, with regard to the anastomosis time and occurrence of postoperative vascular crisis. The ETS group included 22 patients and the ETE group included 40 patients. Patient demographic data, anastomotic time, coupler size, microvascular complications, and flap survival rates were collected and analyzed. In the ETS group, the most suitable donor vessel size was greater than 2 mm, varying from 2 mm to 4 mm. The average anastomosis time was 3.35 ± 0.89 min in the ETS group and 7.80 ± 2.93 min in the ETE group; the difference between the groups was statistically significant (p < 0.0001). There were no statistically significant differences in complications or outcomes between the two groups. The ETS venous anastomosis with MCD technique is a better choice for anastomosis when the donor vessel size is greater than 2 mm. In those cases with mismatched veins, ETS venous anastomosis with MCD could significantly reduce the anastomosis time compared to ETE venous anastomosis with MCD after phleboplasties.     

Reliability of the Mangled Extremity Severity Score in the Management of Peripheral Vascular Injuries in Children: A Retrospective Review

This study was aimed to evaluate different management modalities for peripheral vascular trauma in children, with the aid of the Mangled Extremity Severity Score (MESS). A single-center retrospective analysis took place between 2010 and 2017 at University Hospitals, having emergencies and critical care centers. Different types of vascular repair were adopted by skillful vascular experts and highly trained pediatric surgeons. Patients were divided into three different age groups. Group I included those children between 5 and 10 years; group II involved pediatrics between 11 and 15 years; while children between 16 and 21 years participated in group III. We recruited 183 children with peripheral vascular injuries. They were 87% males and 13% females, with the mean age of 14.72 ± 04. Arteriorrhaphy was performed in 32%; end-to-end anastomosis and natural vein graft were adopted in 18% and 29% respectively. On the other hand, 20% underwent bypass surgery. The age groups I and II are highly susceptible to penetrating trauma ( p  = 0.001), while patients with an extreme age (i.e., group III) are more susceptible to blunt injury ( p  = 0.001). The MESS has a significant correlation to both age groups I and II ( p  = 0.001). Vein patch angioplasty and end-to-end primary repair should be adopted as the main treatment options for the repair of extremity vascular injuries in children. Moreover, other treatment modalities, such as repair with autologous vein graft/bypass surgery, may be adopted whenever possible. They are cost-effective, reliable, and simple techniques with fewer postoperative complication, especially in poor/limited resources.     

手术治疗复杂尿道狭窄的技术探讨(附光盘)

尿道狭窄的疗效近年显著提高。对于前尿道狭窄,目前临床上应用口腔黏膜尿道成形术疗效满意,被公认为治疗前尿道狭窄的金标准。但对于长段前尿道狭窄,口腔黏膜移植物选取较长,手术颇为复杂。对于后尿道狭窄(或闭锁)的治疗,狭窄段切除端端吻合术是标准术式,但对于复杂的后尿道狭窄,由于狭窄段长、局部瘢痕较多、术野位置深、局部解剖层次不清而增加手术难度。本文重点阐述相关技术的注意事项和技术要点。     

胆管T型切除端端吻合在胆囊癌根治术中应用研究

End-to-end versus end-to-side anastomoses in free flap reconstruction: single centre experiences

Background: The choice of microsurgical anastomotic technique, end-to-end (ETE) or end-to-side (ETS), is a relevant point in free tissue transfer. The decision-making process of choosing ETE or ETS technique depends on several clinical and perioperative factors. This study evaluates the outcomes of microvascular procedures in a large single centre patient series, focusing on ETE vs ETS arterial anastomoses.

Materials and methods: Between January 2009 and June 2015, 838 patients underwent free flap surgery for reconstruction after trauma, infection, or malignancies. The cases were divided according to the microsurgical technique of the arterial anastomosis into an ETE (n?=?693) and an ETS (n?=?145) group. The series was retrospectively analysed and the two groups compared regarding outcomes.

Results: Overall, there was no significant difference in rates of surgical complications, flap failures, and re-explorations between the patient groups during the 3-months follow-up period.

Conclusion: The presented analysis includes a large series of microsurgical reconstructions evaluating outcomes in respect to type of performed arterial anastomosis. While the decision of performing an ETE or ETS arterial anastomosis must be made according to recipient vessel quality and accessibility, given no change in outcomes, an ETS anastomosis should be performed whenever feasible in order to preserve distal perfusion.     

END-TO-END ANASTOMOSIS AT THE DUODENOJEJUNAL FLEXURE: IS IT SAFE?

Resection of the proximal jejunum in the duodenojejunal junction area is described in four patients, in diverse clinical settings. The conventional approach would have been to perform a gastrojejunostomy because of the possibility of ischaernia at and around the duodenojejunal flexure. A uniform surgical approach was followed for mobilization, resection and end-to-end duodenojejunal anastomosis and the outcome was successful in all cases.
