Objective To discuss the safety and feasibil ity of treating complex renal aneurysm with ex vivo aneurysmectomy and renal revascularization and renal autotransplantation after hand-assisted retroperitoneoscopic nephrectomy. Methods In October 2006, one male patient with complex renal aneurysm was treated. The preoperative color Doppler ultrasonograph, CT and DSA showed that there was an aneurysm (3.4 cm × 4.3 cm × 4.5 cm) located in the main renalartery bifurcation and its five branches of the left kidney. The patient had a history of hypertension with no response to treatment. After successful hand-assisted retroperitoneoscopic nephrectomy, the kidney off-body was perfused by the renal irrigating solution immediately to protect the kidney. Then ex vivo aneurysmectomy and renal artery revascularization were performed, the renal artery was reconstructed with an autologous right internal il iac artery. The reconstructed left kidney was re-implanted into the right il iac fossa. Results The operation was successful and the patient recovered without perioperative complications. The postoperative renal function was normal and the color Doppler ultrasonograph showed that the blood circulation in the transferred renal artery of the right il iac fossa and its branches was smooth, the blood circulation of the renal venous was smooth and no stenosis in the ureter 2 weeks after operation. Thirteen months follow-up showed the blood pressure was recovered to normal and the renal function was normal. Conclusion The method of ex vivo aneurysmectomy and autotransplantation is safe, feasible and minimally invasive for treating complex hilar renal artery aneurysms.
OBJECTIVE: To evaluate the clinical result of repairing degloving injury of hand with abdominal bipedicled subdermal vascular-network flap in emergence. METHODS: From 1994 to 1997, 19 cases with degloving injury of hand were treated with two flaps, one flaps with the inferior epigastric artery as pedicle, another with superficial epigastric artery. The two skin flaps were designed oppositely to cover the injured hands. RESULTS: All the flaps survived. Followed up for 1 to 3 years, the contour of hands were fine. Extension of fingers was normal and opponers of thumbs was good. Range of flexion of metacarpo-phalangeal joints was from 45 to 60 degrees, and the proximal interphalangeal joints was from 10 to 25 degrees. CONCLUSION: For the subdermal vascular network, the bipedicled flaps of abdomen in repair of degloving injury of hand have sufficient blood supply, b resistance to infection, high survival rate, and good contour.
OBJECTIVE: To explore a new surgical approach to repair skin and soft tissue defect of hands. METHODS: Based on the anatomical study of the origin, course, branch, distribution, and anastomosis of the posterior interosseous artery and its recurrent branches in 40 upper limbs of cadavers, the posterior forearm serial flap, pedicled with the posterior interosseous artery and its recurrent branches, was designed and applied clinically in 17 cases to repair the skin and soft tissue defect of hands from August 1998 to July 2000. The size of flaps ranged from 7 cm x 5 cm to 15 cm x 10 cm. All of the cases were followed up for 3 weeks to 6 months. RESULTS: The anatomy study showed that the posterior forearm serial flap had long vascular pedicle, suitable thickness and large skin area. The clinical application indicated that the flaps survived in 16 cases. But flap necrosis at the distal end, sized 2 cm x 3 cm, was observed in one case, in which the defect was repaired by delayed skin grafting, CONCLUSION: The posterior forearm serial flap pedicled with the posterior interosseous artery and its recurrent branch have the character of avoidance of sacrificing the major arteries of the extremity, longer vascular pedicle, larger area and suitable thickness. The posterior forearm serial flap is a safe and easily manipulated surgical approach to repair the skin and soft tissue defect of the hands, especially of the thumb, palm, and proximal part of the fingers.
Objective To share the experience of the diagnosis and treatment of children with hand-foot-mouth disease. Methods We retrospectively analyzed 31 children with hand-foot-mouth disease in our hospital from April 2007 to June 2007 in terms of epidemiology, clinical features, treatment and prognosis. Results The average age of the children was 2.8 years, and 20 out of the 31 cases were from nurseries and kindergartens. Eighteen had clear contact history. Typical signs and symptoms, including oral ulcerative herpes and blister-like rash in extremities, were found in all cases. All the children were cured after timely diagnosis and early treatment with ribavirin, without any severe complications. Conclusion Timely treatment based on early diagnosis and considerate care are important for children with hand-foot-mouth disease. Nurseries, kindergartens and primary schools should attach great importance to relevant prophylaxis and isolation. These are essential for reducing the occurrence and prevalence of this disease.
Objective To investigate an operative method of repairing large skin defect of the forearm and the hand. Methods From July 2003 to September 2008, 11 patients with large skin defect of the forearm and the hand were repaired using bilateral groin flaps in complex with abdominal flaps, including 7 males and 4 females aged 17-55 years old (average33.5 years old). Among the 11 cases, 5 were caused by carding machine and 4 by traffic accident, and the interval between injury and operation was 90 minutes to 6 hours (average 3.5 hours); 2 cases suffered from severe cicatricial contracture deformity in the late stage of burn injury, and the interval between injury and operation was 7 months and 19 months, respectively. The size of skin defect ranged from 42 cm × 12 cm to 60 cm × 16 cm. The flaps harvested during operation was 45.0 cm × 10.5 cm - 62.0 cm × 18.0 cm in size. Pedicle division of the combined flaps was performed 4 weeks after operation. The donor site wound was repaired by direct suturing in 7 cases and by free skin grafting in 4 cases. Results All flaps survived. All incisions healed by first intention. The donor site wound all healed by first intention. Skin graft all survived. All patients were followed up for 2 months to 3 years. The flaps were soft in texture, full in contour, and normal in color. Sensory recovery of the flaps was evaluated according to the Criteria of UK Medical Research Council (1954), 4 cases were in grade S1, 6 in grade S2, and 1 in grade S3. Hand function was assessed by the Criteria of Chinese Hand Surgery Society, 7 cases were graded as excellent, 2 as good, 2 as poor, and the excellent and good rate was 81.8%. Conclusion Combined use of bilateral groin flaps and abdominal flap is an effective approach to repair large skin defect of the forearm and the hand due to its simple operative procedure and satisfying effect.
Objective To investigate the procedure and applications ofantegrade and retrograde dorsal metacarpal flaps with cutaneous branches as pedicles in repairing soft tissue defects of wrist and fingers. Methods From 1995 to 2003, we observed that the proximal and distal branches, deriving from the dorsal metacarpal artery, formed a consistent anastomosis arc subdermally. The anastomosis arc was paralleled to the dorsal metacarpal artery. Antegrade and retrograde dorsal metacarpal flaps could be designed using proximal anddistal branches as pedicles. Twenty-seven cases of soft tissue defects were treated by use of dorsal metacarpal flaps with cutaneous branches as pedicles, including 3 cases of defects on dorsum of hand with antegrade flaps, and 24 cases of defects on fingers with retrograde flaps ( index finger:12 cases; middle finger: 6 cases; ring finger: 4 cases; and little finger:2 cases). The dimensions of the antegrade flaps were 2.0 cm×4.0 cm～4.0 cm×6.0 cm, and the dimensions of theretrograde flaps were 2.5 cm×3.5 cm～3.0 cm×7.0 cm.The incision of the donor site was closed directly. Results All flaps survived. After a follow-up of 13 years, the texture and color of the flaps were good, and the shape and function of the donors were normal. Conclusion The antegrade or retrograde flap pedicled with the distal or proximal cutaneous branches of thedorsal metacarpal artery, is an optimal flap in repairing finger or wrist softtissue defects.
Objective?To approach feasibility, safety, and the application range of pure laparoscopic resection （PLR）, hand-assisted laparoscopic resection （HALR）, and robotic liver resection （RLR） in the minimally invasive liver resection （MILR）. Methods?The clinical data of 128 patients underwent MILR in the Surgical Department of the Shanghai Ruijin Hospital from September 2004 to January 2012 were analyzed retrospectively. According to the different methods, the patients were divided into PLR group, HALR group, and RLR group. The intraoperative findings and postoperative recovery of patients in three groups were compared.?Results?There were 82 cases in PLR group, 3 cases of which were transferred to open surgery；the mean operating time was （145.4±54.4） minutes （range：40-290 minutes）；the mean blood loss was （249.3±255.7） ml （range：30-1 500 ml）；abdominal infection was found in 3 cases and biliary fistula in 5 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （7.1±3.8） days （range：2-34 days）. There were 35 cases in HALR group, 3 cases of which were transferred to open surgery；the mean operating time was （182.7±59.2） minutes （range：60-300 minutes）；the mean blood loss was （754.3±785.2） ml （range：50-3 000 ml）；abdominal infection was found in 1 case, biliary fistula in 2 cases, and operative incision infection in 2 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （15.4±3.7） days （range：12-30 days）. There were 11 cases in RLR group, 2 cases of which were transferred to open surgery； the mean operating time was （129.5±33.5） minutes （range：120-200 minutes）； the mean blood loss was （424.5±657.5） ml （range：50-5 000 ml）； abdominal infection was found in 1 case and biliary fistula in 1 case after operation, but all recovered after conservative treatment； the mean length of hospital stay was （6.4±1.6） days （range：5-9 days）. The operating time （P=0.001） and length of hospital stay （P=0.000） of the RLR group were shortest and the blood loss （P=0.000） of the PLR group was least among three groups. Conclusions?Minimally invasive resection is a safe and feasible. Different surgical procedures should be chosen according to different cases. The robotic liver resection provides new development for treatment of liver tumor.
ObjectiveTo investigate the effectiveness of digital technology in repairing wounds of the hand and foot with anterolateral thigh flap. MethodsBetween September 2013 and September 2014, 16 cases of wounds of the hand and foot were treated with the anterolateral thigh flap. There were 10 males and 6 females, with an average age of 31 years (range, 20-52 years). The causes included traffic accident injury in 8 cases, crushing injury by machine in 6 cases, burning injury in 1 case, and animal biting injury in 1 case. The locations of soft tissue defect were the dorsum of the foot in 5 cases, the ankle in 4 cases, the planta pedis in 1 case, and the hand and forearm in 6 cases. The time was 2 hours to 45 days from injury to hospitalization (mean, 14.3 days). All defects were associated with exposure of bone and tendon. The size of wound was from 9.0 cm×4.0 cm to 29.0 cm×8.5 cm. CT angiography (CTA) was performed before operation, and the appropriate perforator as well as the donor site was selected. Then the Mimics15.0 software was used to reconstruct the data of CTA so as to locate the main perforators, design the three-dimensional models of the anterolateral thigh flap, and simulate operation. The flap was obtained according to preoperative plan during operation. The size of flaps varied from 11 cm×5 cm to 31 cm×10 cm. The donor sites were sutured directly in 14 cases and were repaired by free skin graft in 2 cases. ResultsThe lateral femoral circumflex artery identified by Mimics15.0 software before operation, as well as the starting position of its descending branch, the blood vessel diameter at start site, vascular distribution, the maximum cutting length of the vascular pedicle were consistent with the actual observation during operation. All flaps were harvested and were used to repair defect smoothly. Vascular crisis occurred in 1 flap after operation, and the other flaps survived successfully. The wounds and the incisions obtained healing by first intention, and grafted skin survived completely. All cases were followed up 6-17 months (mean, 9 months). Fifteen flaps had good shape;but a second-stage operation was performed to make the flap thinner in 1 case. At last follow-up, the results were excellent in 3 cases, good in 2 cases, and fair in 1 case according to total active motion (TAM) in 6 cases of hand and forearm injury;the results were excellent in 5 cases, good in 3 cases, and fair in 2 cases according to American Orthopaedic Foot and Ankle Society (AOFAS) in 10 cases of foot injury. The total excellent and good rate was 81.25%. ConclusionThe preoperative individualization design of the flap can be realized through CTA digital technology and Mimics15.0 software;it can reduce the operation risk.
Objective To summarize the clinical experiences of various types of the second dorsal metacarpal artery (SDMA) flap for hand reconstruction. Methods From 1988 to 2003, 139 SDMA flaps were transferred for hand injuries. The flaps were used in 5 types according to vascularization and technique in transplantation:orthograde pedicled island SDMA flaps in 37 cases (cutaneous in 24and teno-cutaneous in 13), retrograde pedicled island SDMA flaps in 25 cases(cutaneous in 19 and teno-cutaneous in 6),double pivot SDMA flaps in 36 cases(cutaneous in 28 and teno-cutaneous in 8), distal perforator branch pedicledflaps in 19cases (cutaneous in 16 and composite in 3), free SDMA flaps in 22 cases (cutaneous in 15 and composite in 7). The skin islands were 3.0 cm×1.5 cm to 6.3 cm×5.0 cm in size. Results Of the 139 flaps, 135 flaps survived completely, 3 survived partially, and1 failed in the operation because of intractable vascular spasm. Follow-up wasdone in 116 cases for 12 to 57 months. The flap had good texture and color match. The twopoint discrimination was 5 to 9 mm in 78 sensate flaps, while it was 10 to 15 mm in 38 nonsensate flaps. In 21 tenocutaneous flaps, the TAM score of range of motion was 60% to 70% of the healthy side. Conclusion The SDMA flap has a constant and reliable vessel and a thin, pliable, and good-quality skin. It is versatile in creatingcomposite flaps. It is a good flap resource for hand and finger reconstruction.
Objective To introduce the application of the pedicled anterolateral thigh flap transferring for coverage of the oversized skin defect of the hand. Methods The pedicled anterolateral thigh flap was transferred to cover the large skin defects of the hands or the skin defects of theabdomen after the abdominal flap transferred to the hand in 5 male patients aged 16-44 years from April 2002 to August 2005. The injured sites were as follows:4 right hands and 1 left hand, including 2 hands injured by a machine and 3 hands injured by burning.The mechanically injured patients underwent an operation within 6 hours after the injury. The burned patients were reconstructed by the flap transferring 4-7 days after the burn when the decayed tissues could be clearly indentified.The areas of the hand defects were 12.19 cm×18.22 cm.The areas of the pedicled anterolateral thigh flaps were 7.12 cm×16.24 cm. The areas of the abdominal flaps were 13.20 cm×19.23 cm.The pedicles were separated 3 weeks after the repairing operation. Results All the flaps survived well and there was no vascular crisis, with the wound healing of the first intention. The skin defects of the hand were covered completely. Five patients were followed up for 6-12 months. The texture of the flaps was soft and the flaps had a good blood circulation. Of the patients, 3 underwent the finger exclusion and degreasing operation 47 months after operation. All the flaps of the hands had protective sensation, which could meet the requirement of the daily life. Conclusion The pedicled anterolateral thigh flap can provide the large coverage for the skin defects of the hands. The risk of the operation can be greatly decreased by obviation of the vessel anastomosis. It can be an optimal choice for themanagement of the oversized skin defects of the hands.
