BACKGROUND: Leakage from the staple line is the most serious complication encountered after sleeve gastrectomy, occurring in 2.4% of surgeries. The use of inappropriately sized staplers, because of variability in stomach wall thickness, is a major cause of leakage. OBJECTIVES: To measure stomach wall thickness across different stomach zones to identify variables correlating with thickness. METHODS: The study comprised 100 patients (52 females)...

Conventional surgical techniques to seal and repair defects in highly stressed elastic tissues are insufficient. Therefore, this study aimed to engineer an inexpensive, highly adhesive, biocompatible, and biodegradable sealant based on a modified and naturally derived biopolymer, gelatin methacryloyl (GelMA). We tuned the degree of gelatin modification, prepolymer concentration, photoinitiator concentration, and crosslinking conditions to optimize the physical properties and adhesion of the photocrosslinked GelMA sealants...

BACKGROUND: Benign liver cysts are common and are often detected incidentally. Most patients do not require intervention. Occasionally, large dominant or multifocal small cysts cause symptoms as a result of rapid growth, secondary infection, intra-cystic bleeding or compression of adjacent organs. AIM: To compare presenting symptoms and outcomes of a consecutive series of patients with benign liver cysts treated either conservatively or by surgical intervention...

BACKGROUND: Anastomotic leakage following colorectal resection remains one of the most significant complications with relevant morbidity and mortality. There is evidence that a higher number of stapler firings for rectal division can affect the leak rate in double stapling anastomosis. However, there are no data concerning compression anastomosis. We present our institutional experience addressing this issue. DESIGN: This is a retrospective review of a prospective institutional database of patients undergoing colonic and rectal resection for benign and malignant indications between January 2008 and December 2014 at the surgical department of the St...

Background A growing number of operations are performed using minimally invasive techniques. Therefore, a lot of new requirements must be met by the staplers currently available. At the present time, the most widely used methods of minimally invasive vascular occlusion involve high-frequency energy, clips, and staplers. The most important quality parameter is burst pressure, which is measured with a variety of experimental set-ups, all of which are subject to criticism. With this study, we want to introduce a fully automated vascular burst pressure measuring system that largely mimics physiological conditions...

BACKGROUND: A number of evidence-based interventions have been proposed to reduce post cesarean wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥ 2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. OBJECTIVE: We sought to estimate the impact of a group of evidence-based surgical measures (prophylactic antibiotics administered prior to skin incision, chlorhexidine-alcohol for skin antisepsis, closure of subcutaneous layer, and subcuticular skin closure with suture) on wound complications after cesarean, and to estimate residual risk factors for wound complications...

Wound closure in primary knee arthroplasty is important both for surgical success, by minimizing the risk of wound complications and infection, and for patient satisfaction with wound care and cosmesis. This article reports the use of a topical self-adhering, pressure-sensitive polyester mesh combined with 2-octyl cyanoacrylate adhesive for final skin closure of primary knee arthroplasty without external staples or sutures. During a 2.5-year period, 360 consecutive primary knee arthroplasty procedures (321 total knee arthroplasty procedures and 39 partial knee arthroplasty procedures) performed by 1 surgeon at 1 institution were reviewed...

BACKGROUND: The benefits of video-assisted thoracoscopic surgery (VATS) have been demonstrated over the past decades; as a result, VATS has become the gold-standard treatment for primary spontaneous pneumothorax (PSP). Due to improvements in surgical technique and equipment, single-port VATS (s-VATS) is emerging as an alternative approach to conventional three-port VATS (t-VATS). The aim of this study was to evaluate s-VATS as a treatment for PSP by comparing operative outcomes and recurrence rates for s-VATS versus t-VATS...
