Lightweight polypropylene mesh fixation in laparoscopic incisional hernia repair

Abstract Introduction: The choice of the mesh and fixation methods in laparoscopic incisional hernia repair is a crucial issue in preventing complications and recurrence. The authors report a series of 40 consecutive laparoscopic incisional hernia repairs, focusing on the use of lightweight polypropylene mesh and on the way of mesh fixation. Material and methods: Forty laparoscopic incisional hernia repairs performed consecutively in 38 patients (16 males, 22 females) were retrospectively evaluated. Patients were divided into two groups depending on tacks used: Titanium tacks vs absorbable tacks. Results: All patients received totally laparoscopic incisional hernia repair by the use of lightweight polypropylene mesh. No major post-operative complications were reported. Post-operative pain (evaluated by VNS) was higher in Group A (titanium tacks, p < 0.05). No differences in follow-up as well as in recurrence incidence (one case in both groups, <6 months time interval) were reported. Conclusions: Securestrap™ absorbable tacks are safe and effective and easy to use and did not increase the risk of mesh dislocation compared with non-absorbable tacks. The specific design well fits the lightweight polypropylene mesh Physiomesh™. Further evaluations in larger randomized studies are needed to confirm these preliminary data.

Upper gastrointestinal symptoms in obese patients and their outcomes after bariatric surgery

Obesity is considered an important risk factor for the development of gastrointestinal (GI) disorders, likely through alterations of GI motility. Even though gastroesophageal reflux disease is the condition mainly studied at present, the prevalence of other upper GI symptoms is also augmented in obese patients. Owing to their chronic trend, these disorders have a bearing on public spending and their correct diagnosis would avoid unnecessary cost-consuming investigations. Furthermore, bariatric surgery dramatically changes GI anatomy and physiology, influencing GI symptom outcomes. The aim of this review is to categorize the available results in a pathophysiological framework in an attempt to set up the correct clinical GI management of obese patients before and after bariatric surgery. This would be helpful in tentatively reducing their considerable economic burden on public health services.

External Jugular Vein Approach for TIVAD Implantation: First Choice or Only an Alternative? A Review of the Literature:

Purpose Totally implantable venous access devices (TIVADs) can be implanted by percutaneous approach (to the subclavian or internal jugular vein) or by surgical approach, through cephalic vein or external jugular vein (EJV). The authors present a review of the literature about EJV approach for TIVAD implantation. Methods A review of articles indexed in MEDLINE (PubMed) and Cochrane Central Register on “EJV access,” “EJV cut-down,” and “TIVADs” was performed, even matching the terms. We gathered articles from papers quoting patient number, specialist involved, number of devices implanted, site and technique of implantation and complications. Results A total of 1,308 TIVAD implantations through EJV have been reported, with a success rate ranging from 73.7% to 100% and a complication rate up to 13%. Only in 4 on 10 series reported (with more than 15 procedures) the EJV approach was the first choice, while in the other 6 series this approach was the alternative after failure of other approaches. Conclusions Despite the lack of consistent series and prospective studies comparing EJV with other approaches, data present in the literature may support the evidence that EJV approach for TIVAD implantation is safe and effective, and may be considered as the first approach in selected patients.

Parathyroid reimplantation with PR-FaST technique in unselected patients during thyroidectomy. A case series with long term follow up confirming graft vitality and parathormone production

INTRODUCTION Parathyroid damage or unintentional excision still affect thyroid surgery and may cause permanent hypoparathyroidism. The only way to recover the excised or ischemic gland functionality is still reimplantation. Many sites of reimplantation have been described, each of one showing both advantages and drawbacks. The aim of this study is to verify results of a new procedure called PR-FaST: Parathyroid Reimplantation in Forearm Subcutaneous Tissue, in a series of unselected patients after long-term follow-up. MATERIALS AND METHODS From January 2013 to October 2015, 296 consecutive total thyroidectomies have been performed) to treat both benign and malignant thyroid diseases. in 42 cases (14.1%), due to an insufficient blood supply or accidental removal, one parathyroid gland was reimplanted with the PR-FaST technique. Post-operative evaluation was carried out by: total serum calcium (Ca), magnesium (Mg) and phosphorus (P) analysis in the 1st and 2nd postoperative days; Ca, Mg, P and serum iPTH from both arms analysis one week after surgery; Ca and iPTH measurement from both arms 1 months, 3, 6 and 12 months after surgery. RESULTS We observed transient hypocalcemia requiring calcium replacement therapy in 5 on 42 (11.9%) patients submitted to PR-FaST. No case of permanent hypoparathyroidism was reported. At 1 week after surgery, only 20 patients (47.6%) showed graft vitality, while the number of patients showing graft vitality arised to 33 (79%) after 1 month and to 39 (92.8%) after three and six months. At 1 year 38 (90.5%) patients showed good graft functionality. Considering levels of serum iPTH from both arms, we observed that in case of graft functionality, samples from reimplanted arm revealed in almost all cases values at least 2-3 folds higher than in non reimplanted arm. CONCLUSIONS Results from this prospective evaluation suggest that PR-FaST is a safe and effective procedure, with potential advantages when compared to other techniques of parathyroid reimplantation, that are mainly the possibility to evaluate graft functionality in the follow-up and the easy and well reproducible technique. Furthermore, it can be applied, when needed, to potentially all patients undergoing thyroidectomy.

Ultrasound-Guided Vein Puncture Versus Surgical Cut-Down Technique in Totally Implantable Venous Access Devices (Tivads): A Prospective Comparative Study on Safety, Efficacy and Complications

otally implantable venous access devices (TI-VADs) consist of a central venous catheter(made of silicone rubber or polyurethane) and asubcutaneously-implanted injection port made oftitanium or plastic, providing a simple, safe, andpermanent means of accessing the vascular systemfor intravenous delivery of drugs and fluids.

Parathyroid Autotransplantation During thyroid Surgery. Where we are? A Systematic Review on Indications and Results

ABSTRACT Introduction: Hypoparathyroidism still represents an important concern in thyroid surgery. Careful dissection with identification and preservation of parathyroid glands in situ remains the best way to maintain gland vitality and avoid post-operative failure. Nevertheless, parathyroid glands are still inadvertently removed in up to 11% of cases. Parathyroid autotransplantation may represent the only way to restore parathyroid gland functionality in case of inadvertent removal or devascularization during thyroid surgery. Despite this, there is still no agreement on the effectiveness of this procedure. The present systematic review is focused on the mainly debated matters regarding the procedure, indications, technique and results. Methods: This review has been carried out according to PRISMA statement and checklist. The research item was: (((parathyroid autotransplantation[Title]) OR parathyroid reimplantation[Title]) NOT hyperparathyroidism[Title]) AND english[Language]. Results: A total of 31 studies have been found according to limitations already described, reporting from 4 to 890 procedures, with a total amount of 4088 PA. Among these studies, there are only 7 prospective case-series evaluations, 2 prospective randomized trials, while the other 22 studies are retrospective evaluations. The main concerns are: when and how to perform autotransplantation; in which anatomical site; which result to be expected, and how to manage and control the graft. Conslusions: Parathyroid autotransplantatin is an important tool to avoid or minimize the risk for hypoparathyroidism following thyroid surgery in selected cases. Parathormone assay can help the surgeon to determine when reimplantation is indicated or not. Further studies could theoretically give definitive results.

CT diagnosis of small bowel obstruction caused by internal hernia from persistent attachment of a Meckel’s diverticulum to the umbilicus by the obliterated omphalomesenteric duct.

We report a case of small bowel obstruction (SBO) caused by internal hernia from persistent attachment of a Meckel’s diverticulum (MD) to the umbilicus by the obliterated omphalomesenteric duct that was diagnosed by multidetector CT and confirmed during laparoscopic surgery. Although clinical, pathological and radiological features of MD and its complications are well known, the diagnosis of MD is difficult to establish preoperatively. CT findings that allow the diagnosis of this very unusual cause of SBO are presented here with laparoscopic surgery correlation.
