The use of a percutaneous closure device for closure of an accidental puncture of the aortic arch; a simple solution for a difficult problem.

Percutaneous closure devices are now often used for closure of the femoral puncture site after percutaneous vascular interventions. We describe a case were an accidental puncture in the aortic arch during placement of a central venous catheter is successfully closed with a closure device.     

Staple versus suture closure of skin incisions in a pig model

The purpose of this study was to find out whether skin staple closure was a reasonable alternative to conventional nylon suture closure. Mechanical strength, histologic characteristics and time of closure were compared in skin incisions made on the backs of Yorkshire swine. The results showed that stapled and sutured wounds have similar mechanical strength up to 21 days. Stapled wounds are substantially narrower and are associated with less inflammation than sutured wounds. Staple closure is much less time-consuming than suture closure.     

The "reading man" procedure: a new technique for the closure of circular skin defects

BACKGROUND: As most of the skin lesions tend to grow in a circular pattern, the resultant defects after surgical removal of these lesions are often circular. Although a number of local flap procedures have been described, alternative techniques are still needed for the closure of circular defects. PURPOSE: Here, a new surgical technique for the closure of circular skin defects is presented. This technique basically uses the extra skin relaxation gained with an unequal Z-plasty maneuver in favor of the defect closure. The procedure is named as "the reading man" because its surgical design resembles the silhouette of a man who is reading a book held in his hand. MATERIAL AND METHODS: In this technique, 2 flaps designed in an unequal Z-plasty manner are used. The first flap is transposed to the defect area whereas the second flap is used for closure of the first flap's donor site. For 3 years, this technique has been used for closure of the circular skin defects in 27 patients (19 men and 8 women) aged from 2 months to 68 years. The defect size was ranging between 1.5 and 14 cm in diameter. RESULTS: A tension-free defect closure was obtained in all patients. All flaps healed with no complications. There was no patient with dog ear formation. A mean follow-up of 15 months (6 months-3 years) revealed an esthetically acceptable scar formation in all patients. CONCLUSION: The reading man procedure was found to be a useful and an easy going technique for the closure of circular skin defects located on various anatomic regions. It enables surgeon to obtain a tension-free closure of considerably large skin defects with minimal scarring and additional healthy skin excision.     

Stapler vs suture closure of pancreatic remnant after distal pancreatectomy: a meta-analysis

Background

Suture closure and stapler closure of the pancreatic remnant after distal pancreatectomy are the techniques used most often. The ideal choice remains a matter of debate.

Methods

Five bibliographic databases covering 1970 to July 2009 were searched.

Results

Sixteen articles met the inclusion criteria. Stapler closure was performed in 671 patients, while suture closure was conducted in 1,615 patients. The pancreatic fistula rate ranged from 0% to 40.0% for stapler closure of the pancreatic stump and from 9.3% to 45.7% for the suture closure technique. There were no significant difference between the stapler and suture closure groups with respect to the pancreatic fistula formation rate (22.1% vs 31.2%; odds ratio, .85; 95% confidence interval, .66-1.08), although there was a trend toward favoring stapler closure. In 4 studies including 437 patients, stapler closure was associated with a trend (not statistically significant) toward a reduction in intra-abdominal abscess (odds ratio, .53; 95% confidence interval, .24-1.15).

Conclusions

No significant differences occur between suture and stapler closure with respect to the pancreatic fistula or intra-abdominal abscess after distal pancreatectomy, though there is a trend favoring stapler closure.     

Decreased re-operation rate for recurrence after defect closure in laparoscopic ventral hernia repair with a permanent tack fixated mesh: a nationwide cohort study

Purpose

To investigate whether defect closure in laparoscopic ventral hernia repair reduces the re-operation rate for recurrence compared with no defect closure.

Methods

Data were extracted from the Danish Ventral Hernia Database. Adults with an elective laparoscopic ventral hernia repair with tacks used as mesh fixation were included, if their first repair was between the 1st of January 2007 and the 1st of January 2017. Patients with defect closure were compared with no defect closure. Re-operation rates are presented as crude rates and cumulated adjusted re-operation rates. Sub-analyses assessed the effect of the suture material used during defect closure and also whether defect closure affected both primary and incisional hernias equally.

Results

Among patients with absorbable tacks as mesh fixation, 443 received defect closure and 532 did not. For patients with permanent tacks, 393 had defect closure and 442 did not. For patients with permanent tacks as mesh fixation, the crude re-operation rates were 3.6% with defect closure and 7.2% without defect closure (p?=?0.02). The adjusted cumulated re-operation rate was significantly reduced with defect closure and permanent tacks (hazard ratio?=?0.53, 95% confidence interval?=?0.28–0.999, p?=?0.05). The sub-analysis suggested that defect closure was only beneficial for incisional hernias, and not primary hernias. We did not find any benefits of defect closure for patients with absorbable tacks as mesh fixation.

Conclusion

This nationwide cohort study showed a reduced risk of re-operation for recurrence if defect closure was performed in addition to permanent tacks as mesh fixation during laparoscopic incisional hernia repair.

     

Use of a vacuum-assisted device to facilitate abdominal closure

The inability for abdominal closure in critically ill surgical patients provides a complex problem. Often, these patients are left with a large ventral hernia, which requires readmission for abdominal wall repair. We are reporting on the use of a vacuum-assisted device (VAD) to facilitate abdominal wall closure. Fifteen patients were enrolled for placement of a VAD. Selection was based on the diagnosis of abdominal compartment syndrome, the inability for abdominal closure at the initial operation, or the inability to close the abdomen upon re-exploration. Ten (67%) patients were successfully closed within 11 days using the VAD. Predictors of successful closure were the duration of VAD placement (< 12 days, P < 0.001), the total amount of VAD output (< 3 L, P < 0.04), the patient's cumulative fluid balance within the first 2 weeks (< 2 L, P < 0.002), or the presence of a systemic infection at the time of attempted closure (P < 0.001). After 6 months, there have been no complications in patients successfully closed with this device. There have been a few recent reports describing VAD abdominal closures. While not successful for every case, the majority of our patients were able to have their abdominal wall closed primarily. We plan to use this technique to help shorten hospital stay and prevent readmission for hernia repair.     

Primary insertion of a silastic spring-loaded silo for gastroschisis

Gastroschisis is traditionally managed by emergency primary closure, with a temporary silo reserved for large defects unable to be closed primarily. We recently have begun primary Silastic (Dow Coming, Midland, MI) spring-loaded silo (SLS) closure followed by elective closure and report our preliminary experience. A total of 15 infants (weight range, 2.1-13.5 kg) at 2 different institutions were treated by SC by 3 different surgeons between 1998 and 2002. A 3-, 4-, or 5-cm (ring diameter) silo was used depending on size of abdominal wall defect. Elective closure was performed in the operating room or at the bedside. Surgical parameters assessed included success of SLS, peak inspiratory pressures (PIPs) pre- and post-SLS closure, total time of staged closure with SLS, time to full feedings, and intra- and postoperative complications. Fifteen of 15 infants were successfully treated by SLS closure followed by elective closure. Two of 15 (13.3%) experienced temporary dislodgement of the silo prior to permanent closure. In both cases, the silo was safely reinserted at the bedside. Comparison of PIP values measured at various stages of SLS closure revealed no significant difference (P > 0.05). Mean times to final fascial closure (3.7 days) and full enteral feedings (22 days) were similar to historical controls obtained from the surgical literature. In 1 case where there was associated intestinal atresia, SLS closure was effective in permitting concomitant elective closure and re-establishment of bowel continuity. All children are alive and well at the time of this report. SLS closure permits safe, gentle, and gradual reduction of the exposed viscera leading to successful permanent abdominal wall closure. Respiratory embarrassment and hemodynamic instability associated with emergent (primary) closure of large abdominal wall defects can thus be avoided.     

Double Opposing-Rhomboid Flaps for Closure of a Circular Facial Defect in a Special Position

Various techniques are used to repair circular defects in special positions on the face. Simple closure will yield unsatisfactory results because of skin tension. As an ideal method of reconstruction, various flaps are used to provide a versatile and safe alternative. The authors applied double opposing-rhomboid flaps, which provided for closure of a circular skin defect without alteration to the original shapes of the vital structures and resulted in an imperceptible scar. With careful designing, 21 patients with circular defects caused by skin tumor excisions to special facial positions have attained effective functional and aesthetic results using this method since 2004.     

Use of a vascularized tunica vaginalis flap for repair of testicular rupture in a pediatric patient

The management of testicular rupture in children with a large tunical defect is challenging. We describe a technique suitable when primary closure cannot be achieved. A 16-year-old boy presented with right testicular rupture. Owing to the large tunical separation and excessive edema, primary closure could not be achieved. A tunica vaginalis flap was then fashioned with a broad-based pedicle to complete closure. The patient had an uneventful recovery. At 4 months postoperatively, the testis was of normal size and position, and the ultrasound findings were normal. The vascularized tunica vaginalis flap provides an excellent alternative method for closure of pediatric testicular rupture.     

Enterostomy closure site hernias: a clinical and ultrasonographic evaluation

BACKGROUND: Parastomal hernia with a reported incidence of up to 50% is a major problem after ostomy formation. Hernias at the closure site may be a problem after the closure of the enterostomy. In this study, in addition to physical examination, we used ultrasonography (USG) in order to find the true incidence of ostomy closure site and laparotomy incisional hernias. METHODS: We examined patients with closed enterostomy sites by both physical examination and USG for the detection of hernias. Risk factors for hernia formation, such as age, gender, body mass index (BMI), ostomy type, and surgical site infections, were determined. RESULTS: The evaluation of 31 patients with ostomies resulted in a 32% incidence of closed ostomy site hernias when patient medical history, physical examination, and ultrasonographic examination were used together. With physical examination and USG, incisional hernias at the laparotomy incision were found in 58% of cases. USG was able to detect hernias which were not clinically evident at the ostomy closure site and the laparotomy wound. BMI, age, gender, ostomy type, and surgical site infection did not have a significant effect on hernia formation. CONCLUSION: Ostomy closure site and laparotomy incisional hernias are important clinical problems with a high incidence after ostomies are closed. Closure of the enterostomy site should be regarded as a hernia repair rather than a simple fascial closure. USG is a valuable clinical tool in combination with physical examination for the detection of minor defects.     

Trocar site closure: a new and easy technique

The GORE (W.L. Gore & Associates, Phoenix, AZ) Suture Passer, a new reusable fascial closure device, is one of the best devices on the market for closure of laparoscopic trocar site wounds. The technique for closure of fascia using this device is described. It is a cost-effective, safe, and easy.     

Preperitoneal Richter hernia after a laparoscopic gastric bypass

Trocar-site incisional hernias are potentially dangerous because of their susceptibility to become Richter hernias. The authors describe a morbidly obese patient in whom developed an unusual type of Richter hernia after a laparoscopic isolated Roux-en-Y gastric bypass at a 10-mm trocar site. Although the fascial closure of the trocar hernia site was intact, a hernia developed through the peritoneum into the preperitoneal space. For morbidly obese patients, the thick preperitoneum is a potential space that allows for the development of a Richter hernia, despite adequate fascial closure. It is recommended that all 10-mm and 12-mm trocar sites be closed, incorporating the peritoneum into the fascial closure to obliterate the preperitoneal space, to prevent this postoperative complication.     

The sandwich design: a new method to close a high-output enterocutaneous fistula and an associated abdominal wall defect

Fistulas draining through large abdominal wall defects are exceptionally difficult to treat and are associated with a very high mortality. This case report describes a new method for closure of these fistulas where prior conservative and surgical treatment had failed. Initial use of a vacuum-assisted closure (VAC) system optimized wound care and led to coverage of the exposed intestines with granulation tissue. The serratus muscle of a composite free latissimus dorsi-serratus flap was used to close the fistula, while the large abdominal wall defect was closed with the musculocutaneous latissimus dorsi flap. Temporary placement of a VAC system between the serratus muscle and the latissimus dorsi muscle immobilized the serratus to the fistula and counteracted changes in abdominal pressure. The layering of muscle, VAC system, and muscle resembles a sandwich. The advantage of the sandwich design is an extraperitoneal approach that provides tension-free closure of the fistula and abdominal wall, with well-vascularized tissue.     

Delayed primary closure of fasciotomy wounds with Wisebands, a skin- and soft tissue-stretch device

BACKGROUND: Fasciotomy incisions for limb compartment syndrome usually cannot be closed primarily. The conventional method of wound closure with split-thickness skin grafting is effective, but it results in an insensate and disfiguring wound and is associated with donor site morbidity. We present our experience in delayed primary closure of fasciotomy wounds with Wisebands (WB), a skin- and soft tissue-stretching device. PATIENTS: Between 2000 and 2003, we treated 16 patients with extremity fasciotomy wounds for which primary closure was not feasible. RESULTS: The Wisebands devices achieved controlled stretching of the wound edges, including skin and underlying soft tissue, until primary closure was feasible. Fourteen patients (88%) had successful wound closure, two patients (12%) had minor wound complications that did not necessitate the removal of the device, and two patients had local wound complications (infection, intractable pain) and their devices were removed prematurely. Delayed primary closure was achieved at the initial surgery using intraoperative skin stretching in 3 of the 14 cases (21%). After a 2-year follow-up (1.3-4 years), the treated area showed stable scarring with good aesthetic outcome and no functional deficit. CONCLUSIONS: The Wisebands device facilitates closure of fasciotomy wounds with low complication rates and good functional and aesthetic outcome. Its application is simple and safe and requires a short learning curve. Nevertheless, appropriate patient selection, intraoperative judgment and close postoperative supervision are essential for optimal results.     

Temporary silastic mesh closure for adult liver transplantation: a safe alternative for the difficult abdomen.

Primary fascial closure is often difficult after adult orthotopic liver transplantation (OLT), complicated by donor-to-recipient graft size mismatch, post-reperfusion hepatic edema, coagulopathy, or intestinal edema. Attempts at closing the abdomen under these circumstances can cause increase in intra-abdominal pressures, resulting in significant complications, including graft loss. Temporary closure with silastic mesh has been used as a viable option in children receiving transplants, but there is no experience recorded with its use in adults. A retrospective review was conducted on 200 consecutive liver transplantations performed over 42 months (October 2002 to February 2006). Records were evaluated for patient and donor demographics, perioperative factors including Model for End-Stage Liver Disease and Child-Turcotte-Pugh scores, indications for OLT, ischemic times, blood product administration, and use of temporary silastic mesh closure. Patients requiring silastic mesh were further evaluated for indication, time to primary fascial closure, duration of intubation, length of stay, graft function, and complications (infectious, vascular, biliary, and hernia development). Comparisons were made with a cohort of patients undergoing OLT over the same time period but who were closed primarily, without the use of temporary silastic mesh. Fifty-one liver transplantations (25.5%) of the 200 total transplant cohort used silastic mesh closure. Comparison of the cohorts (primary closure vs. temporary mesh) revealed that no differences existed, except the requirement of all blood products was significantly greater in the silastic mesh group (P < 0.001). Bowel edema (47.1%) and coagulopathy (37.3%) were the most common indications for mesh closure, with less frequent reasons including donor to recipient size mismatch (11.8%), hemodynamic instability, and a large preexisting fascial defect (2.0% each). The average time from transplant to final fascial closure was 3.4 days (range 2-9 days). In the silastic cohort, 41 transplants where closed primarily, 3 required the addition of synthetic mesh, and 6 had component separation and flap closure. After fascial closure, the mean time to extubation was 1 day. The median length of follow-up was 1.3 years for the silastic closure group. Long-term wound complications in the silastic closure group included 1 instance of colonic fistula, 2 incisional hernias, and 2 wound infections. The 30-day and 1-year patient survival for this group were 93.6 and 82.4%, respectively, and the graft survival for those same periods were 90.2 and 77.7%, respectively. Wound complications, rates of hepatic artery thrombosis or stricture, portal vein thrombosis or stricture, biliary complications, and allograft and patient survival were no different than those in patients undergoing initial primary closure. In adult liver transplantation with a difficult (or potentially difficult) abdomen, temporary closure with silastic mesh was found to allow for uncomplicated fascial closure in a short period of time, with rapid extubation times, excellent graft function, and minimal instances of infectious or wound complications. In circumstances where large amounts of blood products are required, where a size mismatch exists, or where bowel edema is present during adult liver transplantation, temporary closure with silastic mesh is an ideal strategy.     

Comparing over-the-scope clip versus endoloop and clips (KING closure) for access site closure: a randomized experimental study

Background

A safe technique is essential for successful access site closure in Natural Orifice Translumenal Endoscopic Surgery (NOTES) and for closures of iatrogenic perforations.

Aim

To compare an over-the-scope clip (OTSC) versus an endoloop + endoclips closure technique (KING closure).

Methods

40 minipigs underwent NOTES peritoneoscopy with liver biopsy. Gastrotomies and rectotomies were closed with OTSC (n = 20; 10× stomach, 10× rectum) or KING closure (n = 20; 10× stomach, 10× rectum). The animals were euthanized 28 days after the procedure. The main outcome variables were technical feasibility, effectiveness, and healing.

Results

Stomach: All but one closure (KING) was successfully completed. The times of closure were similar between the techniques. At necropsy, all access sites were healed. In two animals (1× KING, 1× OTSC), an abscess, probably related to the closure technique, was found. Histologically, transmural healing with muscular bridging was observable in nine pigs for KING versus two pigs for OTSC closure (p = 0.003). Inflammation was present in three pigs for KING versus seven pigs for OTSC closure (p = 0.08). Rectum: All closures were successfully completed. The times of closure were similar between the techniques. At necropsy, all closure sites had healed. Transmural healing with muscular bridging was present in nine pigs for KING versus two pigs for OTSC closure (p = 0.003). Inflammation was present in two pigs for KING versus seven pigs for OTSC closure (p = 0.03). In one animal (OTSC), an enterocolic fistula developed in the proximity of the closure site.

Conclusions

OTSC and KING closure are comparable closure techniques in terms of technical feasibility and effectiveness. KING closure provides a superior histological outcome compared with OTSC closure.     

Elevation as a treatment for fasciotomy wound closure

There are currently numerous techniques described in the literature that attempt to optimize wound closure following a fasciotomy. However, primary closure of fasciotomy wounds continues to be difficult to accomplish successfully because of the underlying edema sustained from the compartment syndrome. The approach described in the present report is simple and physiologically sound, and addresses the underlying pathology. The authors focus on alleviating edema by strictly elevating the limb, followed by primary closure. Twelve consecutive fasciotomy wounds, referred from 2005 to 2012, were closed using this approach. The average wound closure time was 3.4 days (range three to five days) following the initial consultation. All 12 fasciotomy wounds responded with no revisions, complications, failures or loss of skin sensation. The approach was successful in all anatomical locations that were closed and conversion to any techniques currently available in the literature was not necessary. There are no costs associated with this approach, making it practical in settings with limited resources. It has a high success rate, superior cosmetic results and, most importantly, it achieves an efficient closure time. Therefore, this approach is superior to current techniques and should be a part of a plastic surgeon’s armamentarium.     

Methods for avoiding a dire surgical complication: Bronchopleural fistula after pulmonary resection

Bronchopleural fistula after pulmonary resection represents a dire surgical complication associated with a high mortality. Suture and staple closure are both associated with a small but significant incidence of bronchopleural fistula (2.6 percent). Both techniques have their proponents, as do methods of reinforcing the closure. None are totally preventive. Carcinoma in the bronchial suture line, the method of reinforcement of the stump, and the way a particular surgeon performs either technique are significant determinants of outcome. To further define determinants of outcome, the operative notes should consistently define the type of stapler, the size of the staples used, the length and thickness of the bronchus, and problems encountered in closure. Frozensection analysis of the bronchial resection margin should be obtained for proximal lesions. Reresection, bronchoplasty, and further reinforcement of the closure may be indicated.     

25-year experience of using a linear stapler in laryngectomy

BACKGROUND: Stapler application for pharyngeal closure after total laryngectomy allows for rapid watertight closure without field contamination and for potentially reduced fistula rate. METHODS: One thousand four hundred fifteen patients underwent laryngectomy with linear stapler closure. In 98.6%, laryngectomy was performed after radiation failure. RESULTS: A relatively high incidence of pharyngeal fistulae (12%) was seen, although these rates were reduced to 5.5% during the recent decade. Simultaneous creation of tracheoesophageal fistula and myotomy by a novel technique was introduced. Swallowing problems were observed in 11 patients and local recurrences in nine patients (0.6%). CONCLUSION: The advantages of mechanical sutures with the closed stapling technique are simple and rapid application, watertight closure with good hemostasis, prevention of field contamination, good speech and deglutition, no increase in fistula rate, and low local recurrence rates. Operating room expenses may also be significantly reduced, rendering this method cost-effective as well.     

Surgical removal of an embolised patent ductus arteriosus amplatzer occluding device in a 4-year-old girl

Alternative strategy of non-surgical closure of patent ductus arteriosus (PDA) is presently the first line of therapy. Several devices are being used for transcatheter closure of PDA. A four-year-old girl underwent a second attempt at PDA closure with an amplatzer device. However, after the deployment of the device it got dislodged into the right pulmonary artery hilum. Several attempts by catheter retrieval failed. The girl underwent surgical removal of the device which was complicated by pulmonary artery injury and subsequent repair was performed on cardiopulmonary bypass.
