BACKGROUND: Pneumothorax during surgery under general anesthesia is a life-threatening situation for the patient because it can progress easily to the tension pneumothorax due to positive pressure ventilation unless appropriate treatments such as inserting a drainage tube in the thoracic cavity are initiated. The authors experienced a case of intraoperative pneumothorax and the diffuse dissection of visceral pleura during liver transplantation surgery, and achieved successful repair by a trans-diaphragmatic approach without changing patient's body position...

BACKGROUND: Laparoscopic right hemicolectomy has become an acceptable treatment for right-sided colon cancer. Most centers use multiport laparoscopic right hemicolectomy extracorporeally (MRHE), whereas single-incision laparoscopic right hemicolectomy intracorporeally (SRHI) remains controversial. The aim of this study was to compare these two techniques using propensity score matching analysis. METHODS: We analyzed the data from 111 patients who underwent laparoscopic right hemicolectomy between December 2015 and December 2016...

PURPOSE: This study compares the posterior corneal elevation and corneal biomechanics after small incision lenticule extraction (SMILE) and laser-assisted subepithelial keratomileusis (LASEK) for myopia correction in a short- and long-term observation. METHODS: This prospective study included 32 patients in the SMILE group and 32 patients in the LASEK group. Corneal posterior central elevation (PCE), posterior mean elevation (PME), corneal back power (Kb), and anterior chamber depth (ACD) were evaluated with Pentacam, and intraocular pressure (IOP), corneal hysteresis (CH), and corneal resistance factor (CRF) were evaluated with the ORA at pre-operation and 3 months and 3 years post-operation...

Bullet embolization of the arterial or venous systems is a rare complication of penetrating gunshot injuries. A 29-year-old man presented at the emergency department with a gunshot wound to the left arm, which had transfixed the arm and entered the thorax, with no exit wound. Initial radiographies showed a projectile in the upper left thigh. Contrast-enhanced tomography showed a pseudo-aneurysm of the descending thoracic aorta and the bullet inside the proximal left superficial femoral artery. Physical examination found diminished left pedal pulses, and the patient complained of left toe numbness...

AIM: To assess the efficiency of endoscopic trans-esophageal submucosal tunneling surgery (EESTS) technique for diseases located around the aorta ventralis. METHODS: Nine pigs were assigned to EESTs. The procedures were as follows: First, a long esophageal submucosal tunnel was established. Second, full-thickness myotomy was created. Third, an endoscope was entered into the abdominal cavity through a muscle incision and the endoscope was around the aorta ventralis...

INTRODUCTION: Many patients have haemorrhagic and neurologic complications after surgery at the symphysis region, while this area between the mental foramina is commonly considered to be risk-free because the presence of vasculo-nervous anastomoses found in the mandibular incisive canal (MIC) and lingual foramina (LF). The purpose of our study was to better analyse these anatomical structures to better identify and preserve them during surgery. PATIENTS AND METHODS: This prospective radio-anatomical study evaluated the presence, morphology and topography of MIC and median LF (MLF) and paramedian LF (PLF) by cone-beam computed tomography according to age, gender and dentition of 50 consecutive patients...

Objective: To investigate the efficacy of single-portal arthroscopic-assisted reduction technique in the developmental dislocation of the hip in infants. Methods: From January 2014 to December 2016, 12 dislocated hips in 12 children with a median age of 14 months (10 to 20 months) were treated with single-portal arthroscopic-assisted reduction technique. The indication for intervention was failure of closed reduction after bilateral adductor and unilateral iliopsoas release under anesthesia. Adductor and iliopsoas tendon were released routinely through a medial approach...

Selecting an appropriate surgical approach for resection of huge skull base tumors involving pterygopalatine and infratemporal fossa is challenging because of their rarity and high possibility of vital anatomical structure injuries. To suggest the guidance of selecting the appropriate approach by analyzing outcomes and satisfactions of known surgical approaches with our previous experience, the authors retrospectively analyzed skull base tumor cases experienced for 24 years, and condensed to 4 well-known surgical approaches: maxillary swing, infratemporal fossa type C, transzygomatic, and a combined transzygomatic-midfacial degloving approach: to review indications, advantages, and limitations of these approaches...

AIM: To evaluate the efficacy of single-incision laparoscopic surgery for totally extraperitoneal repair in overweight or obese patients. MATERIALS AND METHODS: For outcome analyses, patients were subdivided by body mass index (BMI) as normal-weight (18.5≤BMI<25 kg/m), overweight (25≤BMI<30 kg/m) or obese (≥30 kg/m) and compared. RESULTS: In total, 201 patients were divided into a normal-weight group (n=152) and an overweight/obese group (n=49)...

BACKGROUND AND OBJECTIVES: Ketamine has been shown to reduce chronic pain; however, the adverse events associated with ketamine makes it challenging for use outside of the perioperative setting. The ketamine metabolite (2R,6R)-hydroxynorketamine ((2R,6R)-HNK) has a therapeutic effect in mice models of depression, with minimal side effects. The objective of this study is to determine if (2R,6R)-HNK has efficacy in both acute and chronic mouse pain models. METHODS: Mice were tested in three pain models: nerve-injury neuropathic pain, tibia fracture complex regional pain syndrome type-1 (CRPS1) pain, and plantar incision postoperative pain...

In the twentieth century the heavily channelized Raba River incised deeply in its mountain course. Abandonment of channelization structures in a 2.3-km-long reach within a forested corridor was followed by considerable channel widening during floods of 30- and 35-year recurrence interval, re-establishment of a multi-thread channel pattern and island development. Morphological and botanical surveys were conducted annually between 2011 and 2017 to determine the processes and patterns governing development of islands and their floristic complexity...
