ObjectiveTo investigate the effectiveness of multiple tension reduction suture of in-situ return needle vertical mattress suture and in-situ return needle horizontal mattress suture combination with intradermal intermittent continuous suture (denominated as Zunyi’s Suture Method) on suturing the donor site of the anterolateral thigh flap. MethodsBetween January 2019 and December 2019, 62 patients were treated with anterolateral thigh flaps to repair wounds. There were 46 males and 16 females, aged 9-67 years (mean, 31 years). The size of anterolateral thigh flap ranged from 6 cm×5 cm to 25 cm×7 cm. The donor site of the flap was sutured directly by the Zunyi’s Suture Method. The skin on both sides of the incision was advanced to the middle, and the wound edge was attached and in a state of negative tension. The intradermal suture line was removed at 7 days after operation. The complications and scars at donor site were observed during follow-up. The Vancouver Scar Scale was used to assess the appearance of scars and the width of scars were measured at 6 months after operation.ResultsThe flaps survived smoothly, and the wounds healed by first intention. The incisions at donor sites healed by first intention at 2 to 3 weeks after operation. All patients were followed up 7-16 months, with an average of 10.7 months. There was no ischemic necrosis of the donor site or skin threading. There was pigmentation of the needle back point in the early stage, and the pigmentation completely disappeared after 3 to 6 months without scar hyperplasia. At 6 months after operation, liner scars were achieved in all the patients with an average Vancouver Scar Scale score of 2.5 (range, 1.0-3.5) and an average width of 2.4 mm (range, 0.8-9.1 mm). ConclusionThe suture of the donor site of the anterolateral thigh flap with Zunyi’s Suture Method can effectively reduce the tension on wound edges and scar hyperplasia.
ObjectiveTo evaluate the continuous half-thickness suture outside of the pectinate muscles in the right atrium incision in adult patients undergoing cardiac surgery. MethodsA total of 1 040 consecutive adult patients undergoing cardiac surgery by the right atrium incision with cardiopulmonary bypass (CPB) were randomly divided into a control group (n=518 with 236 males and 282 females at mean age of 44.55 years) and a trial group (n=522 with 242 males and 280 females at mean age 45.75 years) between January 2010 and June 2014. The right atrium incision was sutured by continuous full-thickness suture in the control group and sutured by continuous half-thickness suture in the trial group. After the suture, the bleeding in the right atrium incision was recorded. ResultsAll patients underwent the open-heart operation. Seven patients died of postoperative low cardiac syndrome including four patients in the control group and 3 patients in the trial group. The heart incision was inspected before suturing the pericardium. A total of 203 patients of local active bleeding were stitched again in the right atrium incision in the control group. Only 26 patients were stitched again in the trial group (P<0.001). In the cases of re-exploration for bleeding or tamponade after cardiac operation, 3 patients of bleeding due to the right atrium incision were confirmed in the control group, and no one was confirmed in the trial group. ConclusionThe continuous half-thickness suture in the right atrium incision can prevent the incision bleeding, and avoid locally stitching again in adult patients undergoing cardiac surgery.
ObjectiveTo investigate the effectiveness of arthroscopic all-inside combined with outside-in “suture loop” repair for meniscus bucket-handle tear (BHT).MethodsBetween August 2016 and May 2019, 44 case of meniscus BHT were treated with arthroscopic all-inside combined outside-in “suture loop”. There were 29 males and 15 females with an average age of 26.6 years (range, 18-42 years). The causes of injury included sports injury in 31 cases, falling injury in 7 cases, and sprain in 6 cases. There were 32 cases of medial meniscus posterior horn tears and 12 cases of lateral meniscus posterior horn tears. The disease duration ranged from 6 weeks to 3 months. Thirty-three cases were complicated with anterior cruciate ligament rupture. All patients had normal lower limb alignment. The preoperative Lysholm score was 42.1±9.1. According to the evaluation criteria of MRI and Barrett et al., the healing of meniscus was evaluated, and the effectiveness was evaluated by Lysholm score.ResultsAll the 44 patients were followed up 8-36 months with an average of 16.8 months. At last follow-up, according to the evaluation criteria of Barrett et al., 39 cases were clinically healed, 5 cases were not healed, the clinical healing rate was 88.6%; according to MRI evaluation, 32 cases were completely healed, 7 cases were partially healed, and 5 cases were not healed, the total healing rate was 88.6%, and the complete healing rate was 72.7%. Lysholm score was 87.8±4.8, which was significantly different from that before operation (t=31.060, P=0.000).ConclusionArthroscopic all-inside combined with outside-in “suture loop” repair is a reliable and effective method for the meniscus BHT, which can obtain good joint function.
Objective To investigate the effectiveness of modified percutaneous suture in repairing acute closed Achilles tendon rupture by comparing with conventional open suture. Methods Between January 2006 and October 2009, 50 patients with acute closed Achilles tendon rupture were treated with modified percutaneous suture by making 5 small incisions at both sides of Achilles tendon and zigzag suture (improved group, n=22) and with Kessler suture (conventional group, n=28), respectively. No significant difference was found in gender, age, time from injury to operation between 2 groups (P gt; 0.05). Results In improved group, the patients achieved healing of incisions by first intention after operation and nocomplication occurred; however, incision infection occurred in 1 case, Achilles tendon re-rupture in 1 case, and incision scar contracture in 2 cases in conventional group. The operation time of improved group [(38.7 ± 6.6) minutes] was significantly shorter (t= —12.29, P=0.00) than that of conventional group [(52.3 ± 6.9) minutes]; the blood loss of improved group [(4.9 ± 2.0) mL] was significantly less (t= —25.20, P=0.00) than that of conventional group [(40.7 ± 7.1) mL]. The patients were followed up 2-3 years (mean, 29.9 months). The American Orthopaedic Foot and Ankle Society (AOFAS) score was 99.6 ± 1.0 in improved group and was 98.4 ± 3.0 in conventional group, showing no significant difference between 2 groups (t=1.66, P=0.10). Conclusion Comparison with conventional open suture, modified percutaneous suture has some advantages, such as easy operation, less complications, rapid recovery of limb function, and so on. Modified percutaneous suture is one of the best choices for the treatment of acute closed Achilles tendon rupture.
Objective To evaluate the effectiveness and feasibility of a transverse small incision intrathecal “loop” minimally invasive suture for acute Achilles tendon rupture. Methods The clinical data of 30 patients with acute Achilles tendon rupture treated with transverse small incision intrathecal “loop” minimally invasive suture between January 2022 and October 2023 was retrospectively analyzed. The patients were all male, aged from 29 to 51 years, with an average of 39.8 years. The cause of injury was acute sports injury, and the time from injury to operation was 1-14 days, with an average of 3.4 days. The operation time, incision length, intraoperative blood loss, intraoperative complications, wound healing, and hospital stay were recorded. Postoperative appearance and function of ankle were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Vancouver Scar Scale (VSS) score, and Arner-Lindholm score. Results The operation time ranged from 30 to 90 minutes, with an average of 54.2 minutes; the incision length ranged from 1.3 to 3.5 cm, with an average of 2.2 cm; the intraoperative blood loss ranged from 5 to 70 mL, with an average of 22.3 mL; and the hospital stay ranged from 2 to 6 days, with an average of 3.7 days. All incisions healed by first intention, and there was no incision infection, poor healing, and deep venous thrombosis. All patients were followed up 5.3-22.0 months (mean, 14.7 months). During the follow-up, all the 30 patients had returned to exercise, and there was no complication such as Achilles tendon re-rupture, postoperative infection, and gastrocnemius muscle injury. At last follow-up, the AOFAS ankle-hindfoot score was 82-100, with an average of 95.1; the VSS score was 1-4, with an average of 2.1; according to the Arner-Lindholm score, 24 cases were rated as excellent and 6 cases as good. Conclusion Transverse small incision intrathecal “loop” minimally invasive suture for the treatment of acute Achilles tendon rupture has the advantages of simple instrument, convenient operation, small trauma, quick recovery, and satisfactory effectiveness.
