Peri-Operative Prophylaxis in Patients of Neonatal and Pediatric Age Subjected to Cardiac and Thoracic Surgery: A RAND/UCLA Appropriateness Method Consensus Study.

Surgical site infections (SSIs) represent a potential complication of surgical procedures, with a significant impact on mortality, morbidity, and healthcare costs. Patients undergoing cardiac surgery and thoracic surgery are often considered patients at high risk of developing SSIs. This consensus document aims to provide information on the management of peri-operative antibiotic prophylaxis for the pediatric and neonatal population undergoing cardiac and non-cardiac thoracic surgery. The following scenarios were considered: (1) cardiac surgery for the correction of congenital heart disease and/or valve surgery; (2) cardiac catheterization without the placement of prosthetic material; (3) cardiac catheterization with the placement of prosthetic material; (4) implantable cardiac defibrillator or epicardial pacemaker placement; (5) patients undergoing ExtraCorporal Membrane Oxygenation; (6) cardiac tumors and heart transplantation; (7) non-cardiac thoracic surgery with thoracotomy; (8) non-cardiac thoracic surgery using video-assisted thoracoscopy; (9) elective chest drain placement in the pediatric patient; (10) elective chest drain placement in the newborn; (11) thoracic drain placement in the trauma setting. This consensus provides clear and shared indications, representing the most complete and up-to-date collection of practice recommendations in pediatric cardiac and thoracic surgery, in order to guide physicians in the management of the patient, standardizing approaches and avoiding the abuse and misuse of antibiotics.

Place of surgery in the management of post-operative chronic pain after placement of prosthetic material based on a series of 107 cases.

The objective of this study was to evaluate the efficacy of surgical removal of prosthetic material, possibly combined with nerve release, on chronic postoperative pain following placement of prosthetic material. Single-tertiary-centre study on 107 patients managed between November 2004 and April 2016 for removal of prosthetic material responsible for postoperative chronic pain: retropubic suburethral sling (n = 32), transobturator suburethral sling (n = 50), prolapse mesh (n = 16), and hernia mesh (n = 9). The primary endpoint was at least 50% reduction of pain evaluated by a pain numerical rating scale (NRS). The mean interval between the initial operation involving placement of prosthetic material and reoperation for removal of prosthetic material was 41.2 ± 35.4 months. In all cases pain apperaed immediately following prosthetic material placement surgery. Pain presented neuropathic features in almost 30% of cases and was poorly systematized in more than one-half The mean follow-up of the study population was 8.4 ± 10.3 months. The mean pain NRS score for the overall population was seven preoperatively and three at last follow-up. At least 50% reduction of the pain NRS score was observed 67% of cases at last follow-up. During follow-up, 45% of patients experienced relapse of the disorder for which the prosthetic material was initially placed with, in particular, a 62% recurrence rate of urinary incontinence after removal of transobturator suburethral tape. Surgical removal of prosthetic material to treat chronic postoperative pain, achieved global improvement of pain in about two-thirds of cases, but with a risk of recurrence of the initial disorders.

Éventrations. Prothèses infectées : traitement et prévention

En chirurgie propre (Altemeier I), la présence d’une prothèse n’augmente pas l’incidence des infections. Les infections de prothèse sont plus fréquentes et plus graves en ventral qu’en inguinal. L’ablation de la prothèse règle le problème infectieux mais pose d’autres problèmes tout aussi épineux, incitant : (i) à explorer les traitements conservateurs, finalement souvent réalisables, et (ii) au strict respect des mesures préventives. In clean surgery (Altemeier Class I), the incidence of infections is not increased by the placement of prosthetic material. Prosthetic mesh infections occur more frequently and are more serious in ventral incisional repair than in inguinal hernia repair. While removal of the mesh resolves the infectious problem, it creates other problems that are equally difficult. This underscores the need to: (i) explore other conservative hernia treatment options; in the end, these are often feasible; (ii) respect and implement strict measures to prevent infection.

Abdominal wall incisional hernias: Infected prosthesis: treatment and prevention

In clean surgery (Altemeier Class I), the incidence of infections is not increased by the placement of prosthetic material. Prosthetic mesh infections occur more frequently and are more serious in ventral incisional repair than in inguinal hernia repair. While removal of the mesh resolves the infectious problem, it creates other problems that are equally difficult. This underscores the need to: explore other conservative hernia treatment options; in the end, these are often feasible; respect and implement strict measures to prevent infection.

Tension-free repair versus Bassini technique for strangulated inguinal hernia: A controlled randomized study

By Evidence Based Medicine (EBM) principles, several meta-analyses concluded that use of mesh is superior to the non-mesh operations in inguinal hernia surgery. Wound infection is a potential complication of all hernia repairs and deep-seated infection involving an inserted mesh may result in chronic groin sepsis. In the event of incarcerated or strangulated hernias, however; placement of prosthetic material is presumed to increase that risk of infection. Aim Aim of the study is to compare the outcome of tension-free mesh repair to Bassini technique used to treat strangulated inguinal hernia. Patients and methods In the period from May 2004 to December 2006, 54 patients were submitted to emergency operation because of strangulated inguinal hernia. The patients were randomized into two groups (27 patients in each group). Group A patients underwent open tension-free anterior repair utilizing a monofilament polypropylene mesh according to Lichtenstein “tension-free” technique, whereas group B patients underwent Bassini technique. Mesh hernioplasty was not attempted in patients with preoperative peritonitis, inflammatory hernia and for those in whom bowel resection was perfumed for ischemic necrosis caused by strangulated inguinal hernia and they were excluded from the study. Assessment of the primary outcome included surgical complications and hospital stay and secondary outcome was the recurrence of hernia. Results Postoperative complication rate did not differ significantly between the two groups. Postoperative hospital stay was also significantly longer in group B compared to group A (5 ± 3.4 days versus 3 ± 2.1 days, p < 0.01). During the follow-up, (mean 22 ± 6months), three patients had recurrence after Bassini operation (group B), but there was no recurrent hernia after mesh herniorrhaphy (group A) (0/27 = 0% versus 3/27 = 7, 11.1%, p < 0.001). Conclusion The use of Lichtenstein “tension-free” technique in emergency treatment of strangulated inguinal hernia is safe, effective with an acceptably low rate of postoperative complications and without recurrence.

Preliminary results of a two-layered prosthetic repair for recurrent inguinal and ventral hernias combining open and laparoscopic techniques

The use of prosthetic mesh has become the standard of care in the management of hernias because of its association with a low rate of recurrence. However, despite its use, recurrence rates of 1% have been reported in primary inguinal repair and rates as high as 15% with ventral hernia repair. When dealing with difficult recurrent hernias, the two-layer prosthetic repair technique is a good option. In the event of incarcerated or strangulated hernias, however; placement of prosthetic material is controversial due to the increased risk of infection. The same is true when hernia repairs are performed concurrently with potentially contaminated procedures such as cholecystectomy, appendectomy, or colectomy. The purpose of this study is to report our preliminary results on the treatment of recurrent hernias by combining laparoscopic and open techniques to construct a two-layered prosthetic repair using a four ply mesh of porcine small intestine submucosa (Surgisis, Cook Surgical, Bloomington, IN, USA) in a potentially infected field and a combination of polypropylene and ePTFE (Gore-Tex, W.L. Gore and Associates, Flagstaff, AZ, USA) in a clean field. From September 2002 to January 2004, nine patients (three males and six females) underwent laparoscopic and open placement of surgisis mesh in a two layered fashion for either recurrent incisional or inguinal hernias in a contaminated field. A total of eight recurrent hernia repairs were performed (five incisional, three inguinal) and one abdominal wall repair after resection of a metastatic tumor following open colectomy for colon carcinoma. Six procedures were performed in a potentially contaminated field (incarcerated or strangulated bowel within the hernia), two procedures were performed in a contaminated field because of infected polypropylene mesh, and one was in a clean field. Mean patient age was 56.4 years. The average operating time was 156.8 min. Operative findings included seven incarcerated hernias (four incisional and three inguinal), one strangulated inguinal hernia, and one ventral defect after resection of an abdominal wall metastasis for a previous colon cancer resection. In two of the cases, there was an abscess of a previously placed polypropylene mesh. All procedures were completed with two layers of mesh (eight cases with surgisis and one with combination of polypropylene/ePTFE). Median follow up was 10 months. Complications included two seromas, one urinary tract infection, two cases of atelectasis and one prolonged ileus. There were no wound infections. The average postoperative length of stay was 7.8 days. There have been no mesh-related complications or recurrent hernias in our early postoperative follow-up period. The use of a new prosthetic device in infected or potentially infected fields, and the two-layered approach shows promising results. This is encouraging and provides an alternative approach for the management of difficult, recurrent hernias.
