Novel Use of the Perceval Valve for Prosthetic Aortic Valve Endocarditis Requiring Root Replacement

The surgical management of aortic valve endocarditis can be challenging. Infection with abscess formation can destroy the root and annulus, making it difficult to anchor a valve conduit. In this article, we present a novel and efficient strategy for proximal aortic reconstruction. We used a Dacron tube graft and anchored it proximally with a running suture line deep in the left ventricular outflow tract. The coronary buttons were attached, and a Perceval valve was then deployed inside the neo-root to create a bio-Bentall.

Use of hydrocolloid dressing in infants requiring open chest management after cardiac surgery

Purpose Sternal splintage is known as an effective maneuver to stabilize hemodynamics during the immediate postoperative period, particularly in very sick infants. On the other hand, its wound management is not always straightforward. We employed dressing using a product made of a hydrocolloid material in such circumstances. This report describes our experience in utilizing the dressing in term of its potential advantages. Materials and methods Six infants needed open chest management following complicated procedures for congenital heart disease. A polytetrafluoroethylene patch was fixed to augment the skin defect at the time of sternal splintage, and a hydrocolloid dressing was applied to entirely cover the wound including the suture line. Result All patients survived their difficult circumstances. None of them suffered wound complications such as infection or healing problem during sternal splintage or subsequent to eventual chest closure. The dressing product was easy to handle with no adverse events associated with its material. Conclusions It is reconfirmed that a dressing made of hydrocolloid material was of practical use for sealing the wound in infants requiring open chest management after cardiac surgery.

Uses for Incomplete Ammonite Sutures: Lateral Lobe and Second Saddle as Markers of Sutural Complexity

Ammonoid sutures are geometric patterns formed by the intersection of the septa and the shell wall, and have long been a diagnostic tool for ammonite researchers for such applications as species identification, taxonomic relationships, ontogenetic change, functional and evolutionary morphology, determination of ecological niche, and other aspects of ammonoid paleobiology. Researchers interested in a variety of paleobiological questions related to ammonoids have almost always required access to the entire hemisuture. Without access to specimens in museum or institutional collections, researchers must rely on previously published illustrations and photographs of ammonoid sutures. However, due to the perspective in photographs, distortion of the marginal elements of suture geometry occurs due to shell curvature near the venter and umbilicus when photographed in profile. The revised approach described here, which we refer to as the Lateral Lobe Saddle, or LLS approach, makes use of only the lateral lobe and second saddle S2 (lateral lobe-second saddle pairs, or LLS) which lie in the central, mid-whorl undistorted sector of a suture line as viewed in lateral, profile shell photos and illustrations. The factors by which fractal dimension of LLS data convert to fractal dimension of the standard hemisuture measurements are largely consistent within genera. The LLS method’s non-requirement of a full hemisuture also facilitates comparisons among sutures within an ontogenetic sequence, or sutures from multiple ammonite taxa where ventral and umbilical sutural elements are hidden by whorl overlap or poor preservation.

Postinfarction ventricular septal defect closure

After a median full sternotomy, cardiopulmonary bypass is installed in the usual manner. Apical ventriculotomy is performed through the infarcted myocardium. Polypropylene pledgeted mattress sutures are passed from the right to the left ventricular side through the ventricular septal defect, with the pledgets remaining on the right ventricle. Great care must be taken to place the suture on healthy myocardium and away from the edge of the ventricular septal defect; otherwise the chances of a recurrent postoperative ventricular septal defect would increase. The sutures are subsequently positioned through a heterologous patch, previously prepared to be appropriate for the ventricular septal defect closure. A collar of 3 to 4 cm is left on the external side of the patch. A 4-0 polypropylene running suture is placed through this collar and the left ventricle to further reinforce the ventricular septal defect closure. The left ventricular incision is closed with polypropylene 3-0 continuous sutures. For each ventricular edge, the running suture is passed through 2 polytetrafluoroethylene felts: one on the endoventricular side and the other on the epicardial side. Finally, the suture line is reinforced with a continuous 2-0 polypropylene suture, which is passed through the polytetrafluoroethylene felts, the ventricular wall, and the heterologous patch used to close the ventricular septal defect.

SPONTANEOUS RUPTURE OF THE RIGHT CONGENITAL DIAPHRAGMATIC EVENTRATION ON THE RIGHT SUBJECTED TO SURGICAL CORRECTION IN A CHILD WITH MEGADOLICOCOLON

Спонтанний розрив гемідіафрагми у випадках вродженої діафрагмальної евентрації зустрічається вкрай рідко, у літературі повідомляють про унікальні випадки.In this context, the authors present the case of an 8-year-old child who was hospitalized in the coloproctology service for abdominal pain, lack of stool for more than 7 days, pronounced abdominal distension. The child suffers from Down's disease. In 2017, he was occasionally diagnosed with right diaphragmatic eventration and underwent surgical correction by thoracic approach. After a thorough evaluation, with signs suggestive of diaphragmatic hernia on the right, the child underwent surgery, intraoperatively the rupture of the right hemidiaphragm was found with intrathoracic ascension of the malrotated intestinal loops, transverse colon and omentum. The repair of the diaphragmatic eventration complicated by rupture was used using the “overcoat” folding procedure, on the suture line being carefully applied a collagen foil covered with components of the fibrin adhesive. The postoperative period passed without complications.Conclusion. Spontaneous rupture of the diaphragm is a rare complication in children with diaphragmatic eventration, especially on the right side, in this case obstruction of the malformative colon ascended intrathoracically with progressive dilation of the intestinal loops being responsible for distension with gradual thinning of the hemidiaphragm sac resulting malformation in diaphragmatic rupture with herniation and progressive obliteration of the pleural space. The case of rupture of the diaphragmatic eventration associated with megadolicocolon confirms that the respiratory symptoms characteristic of this clinical situation may be overshadowed by the predominance of signs of intestinal obstruction, without leading to sudden progressive clinical deterioration, which proved to be a misleading moment in diagnosis. certainty of this serious complication rarity.

OV07 LAPAROSCOPIC HIATAL HERNIA MESH-SUTURE REPAIR

Aim “A new original laparoscopic operative technique was used to suture paraesophageal hernia (PEH) with the strips of mesh. Material and Methods The Mercilen (MercilenTM) mesh suture was used to close large hiatal hernia. The strips of mesh, instead of normal thread, were applied to close the gap between diaphragm’s crura in 12 patients with hernia defect more than 5 cm. Mesh suture were tighten as a simple laparoscopic intracorporeal knot. The surgical technique and surgical outcomes are presented. Results 12 patients underwent a laparoscopic PEH suturing with Mercilen strips of mesh. We recorded no recurrence or dysphagia at 6 and 12 months follow-up. Conclusions Mesh-sutured repairs of diaphragm’s hernia support the concepts of force distribution and resistance to suture pull through. The new original technique avoids using the sheet of mesh and enables to reduce the amount of dangerous complications connected with mesh and its fixation. Mesh-sutured closures of hiatal hernias seem to be safe and effective in tension closure of large hiatal defects. Further investigations are needed to evaluate the results. Using the mesh suture technique for the closure of large PEH, we protect the cruras from being cutting through. Besides, the mesh stripes and its knots produce tissue scarring around the esophagus making the suture line stronger.

OV05 CONCOMITANT MIRS (MINI INVASIVE RIVES STOPPA) AND DREAM (DIASTASIS REPAIR ENDOSCOPICALLY ASSISTED MINI-INVASIVE) FOR THE CORRECTION OF COMBINED VENTRAL HERNIA AND DIASTASIS RECTI

Aim Concomitant MIRS (Minimally Invasive Rives-Stoppa) and DREAM (Diastasis Repair Endoscopically Assisted Minimally-invasive) for the correction of combined ventral hernias and diastasis recti. Material and Methods The video shows the combined repair of umbilical hernia and diastasis correction by concomitant minimally invasive hernia repair without division of the posterior sheath and diastasis correction by parietoscopy. Results A short periumbilical incision is performed, the Alexis retractor is put in place, preaponeurotic dissection is carried out by direct access and two axial incisions of both anterior sheaths are performed parallel to and 1cm next to the midline. The umbilical hernia and one unexpected epigastric hernia are reduced and repaired by suture. Additional suture approximating the medial borders of anterior sheath incisions over the previous suture is performed to strengthen the repair. The patch is deployed in the retromuscular space superficial to the suture line, without any incision of the posterior sheath and without any fixation. Then the top of the Alexis retractor and the camera are put in place, insufflation at 10mm Hg is started and the parietoscopic step is carried out. Two 5mm trocars are placed and preaponeurotic dissection is extended up to the xiphoid process. The diastasis correction is carried out by a continuous suture approximating both rectus muscles from the xiphoid process to the umbilical hernia suture. Conclusions The MIRS technique consists of retromuscular patch repair without division of the posterior sheath, and concomitant DREAM technique reinforces the hernia repair and provides diastasis correction.

O10 REINFORCED TENSION LINE SUTURE RESULTS IN LOW INCISIONAL HERNIA RATE AFTER CRS/HIPEC OPERATIONS

Aim Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis entails several risk factors for incisional hernia (IH). At our institution fascia closure has been performed in a 4:1 manner with a 2-0 polydiaxanone suture (the PDS-group) or a 2-0 polypropylene preceded by a reinforced tension line (RTL) suture (the RTL-group). Our hypothesis was that reinforcing the suture line results in fewer IH at one year. Material and Methods Single-center retrospective study on primary CRS/HIPEC 2004-2019. CT-diagnosed IH one year ±3 months postoperative. Additional data retrieved from clinical records and a prospective CRS/HIPEC database. Results Of 193 patients, 63 were not evaluable for IH of which two, both in the PDS-group, were reoperated for fascial dehiscence (FD). 130 patients; 83 (45 women) in the PDS- and 47 (23 women) in the RTL-group, mean age 57 years (19-77) remained. RTL-patients were five years younger (54 vs 59), had a higher Karnofsky index and less bleeding (807 vs 1409 mL). No differences regarding sex, BMI, recent midline incisions, excision of midline scars, peritoneal cancer index score, complications (Clavien-Dindo 3b or higher), neo-adjuvant or adjuvant chemotherapy were found. Twelve IH (9%) were found, 11 (13%) in the PDS- and 1 (2%) in the RTL-group (p = 0.055). Conclusions Despite many potential IH risk factors, the overall IH-incidences do not seem higher than after laparotomies in general. The RTL-group showed 2% IH compared to 13% in the PDS-group. The PDS-group were further burdened by two FD. The results are clinically relevant, suggesting an advantage with RTL-closure for these patients.
