Closed Incision Negative Pressure Wound Therapy for Elective Hip and Knee Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BackgroundPersistent wound drainage after total joint arthroplasty (TJA) increases the risk of surgical site infections (SSIs). Closed incision negative pressure wound therapy (ciNPWT) decreases infections in traumatic wounds, but evidence for its use after elective TJA is limited. The purpose of this meta-analysis of level I studies is to determine the effect of ciNPWT on risk of SSI and wound complications following TJA.MethodsMEDLINE, EMBASE, CINAHL, and Cochrane Library were searched for randomized controlled trials comparing ciNPWT vs standard dressings after total hip (THA) and total knee arthroplasty (TKA). Studies exclusively involving THA for femoral neck fractures were excluded. Risk of SSI and noninfectious wound complications (blisters, seroma, hematoma, persistent drainage, dehiscence, and wound edge necrosis) following TJA were analyzed.ResultsSSI risk was lower with ciNPWT compared to standard dressings (3.4% vs 7%; relative risk [RR] 0.48, P = .007), specifically in revision THA and TKA (4.1% vs 10.5%; RR 0.41, P = .03). ciNPWT increased the noninfectious complication risk after primary TKA (RR 4.71, P < .0001), especially causing wound blistering (RR 12.66, P < .0001). ciNPWT decreased hospital length of stay by 0.73 days (P = .04) and reoperation rate (RR 0.28, P = .01).ConclusionciNPWT decreases SSI risk compared to standard dressings after revision TJA, but not primary TJA. ciNPWT is associated with >12-fold increased risk of wound blistering after primary TKA. ciNPWT plays a role in revision TJA management, but additional randomized controlled trials with uniform wound assessment methods must be performed to sufficiently power findings and draw conclusions on the use of ciNPWT after primary TJA.

Reduced port laparoscopic surgery using umbilical zigzag incision for Meckel’s diverticulitis

IntroductionReduced port laparoscopic surgery using an umbilical zigzag incision is comparable to conventional multiport laparoscopic surgery. This method is associated with improved cosmesis and decreased wound pain.Presentation of caseA 67-year-old man visited our hospital. He presented emergency room with a chief complaint of right lower abdominal pain by walking. The patient was diagnosed Meckel’s diverticulitis by computed tomography (CT). At first, antibiotics therapy and fasting were performed. Three months later, the patient underwent resection of Meckel’ diverticulum with zigzag transumbilical laparoscopic surgery. The patient’s postoperative course was good, and he rarely felt wound pain. The patient started oral intake three days after surgery, and was discharged 10 days after surgery.DiscussionZigzag transumbilical laparoscopic surgery is very useful for resection of the small intestine. This method is associated with improved cosmesis and decreased wound pain. In the case of Meckel’s diverticulitis, we suggest that interval resection of Meckel’s diverticulum was very useful as it was an operation that could be performed easily.ConclusionReduced port laparoscopic surgery using an umbilical zigzag incision is considered to be an excellent technique in terms of operability and aesthetic outcomes.     

传统外侧“L”形切口钢板内固定与跗骨窦小切口微型钢板内固定治疗跟骨骨折患者的效果

目的比较传统外侧“L”形切口钢板内固定与跗骨窦小切口微型钢板内固定治疗跟骨骨折患者的效果。方法选取福建医科大学附属三明第一医院2019年1—12月收治的59例跟骨骨折患者,随机分为试验组(31例)和对照组(28例)。对照组采取外侧“L”形切口钢板内固定治疗,试验组采取跗骨窦小切口微型钢板内固定治疗,比较两组的治疗效果。结果试验组手术时间、住院时间均短于对照组,术中出血量少于对照组,差异有统计学意义(P<0.05);两组骨折愈合时间比较,差异无统计学意义(P>0.05)。术后,两组跟骨结节关节角、Gissane角均大于术前,差异有统计学意义(P<0.05);但组间跟骨结节关节角、Gissane角比较,差异无统计学意义(P>0.05)。试验组并发症发生率低于对照组,Maryfand评分、足部功能恢复优良率均高于对照组,差异有统计学意义(P<0.05)。结论跗骨窦小切口微型钢板内固定治疗跟骨骨折患者的效果优于传统外侧“L”形切口钢板内固定,可有效促进患者足部功能恢复,且安全性较高。

The Superiority of the Left Subcostal Incision Compared to Mid-line Incisions in Surgery for Morbid Obesity

We describe a 13-year experience using a left subcostal incision in performing gastroplasties and Roux-en-Y gastric bypasses (RYGBP) in morbidly obese patients. We have also used it successfully in the general population in several other types of surgical procedures, including Nissen fundoplications in adults and infants, gastrectomies, truncal vagotomies, pyloroplasties, jejunoileal bypass reversals, and elective splenectomies. Over 200 cholecystectomies have been carried out through this incision as additional procedures with relative ease, not requiring any further extension of the incision. There were no hernias in a group of 1067 primary gastroplasty and RYGBP patients, and the wound infection rate has been quite low, apparently because of the incision's distance from the potentially contaminated umbillicus. We feel that the use of this incision further simplifies and therefore adds a safety factor not seen with the standard vertical incision in this group of surgical patients.
