BACKGROUND: Extended pancreatic resections including resections of the portal (PV) may nowadays be performed safely. Limitations in distinguishing tumor involvement from inflammatory adhesions however lead to portal vein resections (PVR) without evidence of tumor infiltration in the final histopathological examination. The aim of this study was to analyze the impact of these "false negative" resections on operative outcome and long-term survival. METHODS: 40 patients who underwent pancreatic resection with PVR for pancreatic adenocarcinoma (PA) without tumor infiltration of the PV (PVR-group) were identified...

Neurogenic bladder occur as a consequence of several conditions, most commonly posterior urethral valves syndrome, spina bifida, tethered cord, sacral agenesis, and Arnold-Chiari malformation. It is characterized by diminished bladder capacity and/or reduced compliance, associated with high-pressure voiding that can lead to deterioration of renal function if left untreated. When medical management fails, bladder reconstruction with bowel (aumentation ileocystoplasty) becomes the treatment of choice for these patients...

Objective: To evaluate the adhesion effect of tissue engineering retinal nerve scaffolds modified with biological glue. Methods: Experimental study. To fabricate a biological glue by blending laminin, collagen Ⅳ, entactin and HSPG(2) with phosphate-buffered saline (PBS) buffer solution, scaffolds were then modified with the biological glue of various concentration levels (10 μl/cm(2), 20 μl/cm(2), 30 μl/cm(2) and 40 μl/cm(2)). The effects of various concentration levels glue on inducing scaffold adhesion were analyzed after 24 h...

To improve intraperitoneal chemotherapy and to prevent postsurgical peritoneal adhesion, we aimed to develop a drug delivery strategy for controlled release of a chemotherapeutic drug from the intraperitoneally injected thermosensitive poly( N -isopropylacrylamide)-based hydrogel (HACPN), which is also endowed with peritoneal anti-adhesion properties. Anticancer drug doxorubicin (DOX) was loaded into the hydrogel (HACPN-DOX) to investigate the chemotherapeutic and adhesion barrier effects in vivo. A burst release followed by sustained release of DOX from HACPN-DOX was found due to gradual degradation of the hydrogel...

Background: Cauda equina syndrome (CES) is a rare complication of spinal or epidural anesthesia. It is attributed to direct mechanical injury to the spinal roots of the cauda equina that may result in saddle anesthesia and paraplegia with bowel and bladder dysfunction. Case Description: The first patient underwent a hip replacement and received 5 mL of 1% lidocaine epidural anesthesia. Postoperatively, when the patient developed an acute CES, the lumbar magnetic resonance imaging (MRI) scan demonstrated clumping/posterior displacement of nerve roots of the cauda equina consistent with adhesive arachnoiditis attributed to the patient's previous L4-L5 lumbar decompression/fusion...

Neuroligin 2 is a synaptic cell adhesion molecule that is mainly located in inhibitory synapses and is crucial in the regulation of synapse function through protein-protein interactions. However, researchers have not clearly determined whether neuroligin 2 is involved in the development of postoperative pain. In the current study, Western blot, immunofluorescence staining and co-immunoprecipitation were used to examine the critical role of neuroligin 2 in postoperative pain hypersensitivity. A small interfering ribonucleic acid (siRNA)-targeting neuroligin 2 was used to inhibit neuroligin 2 expression...

Background: The approaches to thoracoscopic thymectomy in myasthenia gravis (MG) are debatable. We developed a novel approach via subxiphoid and subcostal arch, with a significantly shorter duration of operation and hospital stay, less estimated blood loss, and lower postoperative pain. Methods: From December 2012 to December 2014, 77 myasthenia gravis patients with or without thymoma underwent thoracoscopic extended thymectomy at our hospital. Among them, 41 patients were operated via the subxiphoid and subcostal arch approach and the other 36 via the conventional unilateral approach...

INTRODUCTION: An inguinal hernia with an incarcerated appendix is defined as Amyand's hernia, and it is relatively rare. Amyand's hernia complicated with appendicitis, especially perforated appendicitis, is even rarer. Postoperative surgical site infection (SSI) is a dangerous complication, especially in Amyand's hernia with appendix perforation. The selection of an appropriate surgical approach is necessary to prevent postoperative SSI. Here, we report a case of Amyand's hernia complicated with appendix perforation that was successfully managed using a two-stage surgical approach consisting of laparoscopic appendectomy followed by elective inguinal hernioplasty...

OBJECTIVE: The aim of this study was to investigate whether coexistent intraarticular lesions are negative prognostic factors for the results of arthroscopic capsular release in frozen shoulder patients. METHODS: Seventy-two patients who met inclusion criteria and underwent arthroscopic capsular release between March 2011 and August 2015 for the frozen shoulder were retrospectively evaluated. The patients were divided into two groups according to existence of concomitant intraarticular pathologies detected during arthroscopy...
