INTRODUCTION: Single-port laparoscopic surgery has some technical limitations with respect to control of the forceps inserted through the single-access site, which results in increased internal collisions due to coaxial alignment of the instruments, as well as and decreased range of motion and visualization. To overcome these limitations, we employ a "modified marionette technique" as a way to carry out laparoscopic colorectal surgery. Materials and Surgical Technique: The procedures for the modified marionette technique are performed as follows: An Internal Organ Retractor (IOR)™ and an atraumatic clip designed to firmly grasp tissue, with 1-0 nylon thread, are inserted through a 12-mm trocar and secured in place where adequate visualization and traction for cutting with a radio knife is required...

Prosthetic mesh infection after open or laparoscopic hernia repair is a rare complication. Superficial wound infection can be resolved by treatment with a combination of antibiotics and wound drainage, whereas deep-seated mesh infection, which can lead to chronic groin sepsis, usually requires removal of the mesh. A 56-year-old Japanese man was admitted to our hospital for the treatment of deep-seated mesh infection. The patient had undergone inguinal hernia repair at another hospital 18 months earlier. The operation was prosthetic mesh repair via an anterior approach...

Traumatic chopstick injury is very rare, especially in the vascular system. We present an unusual case of a 19-year-old man who presented at the emergency department after being stabbed with a chopstick by his elder brother. Computed tomography revealed a left subclavian artery pseudoaneurysm, which increased from 4 mm to 7 mm in diameter within 47 days. We successfully deployed a Niti-S stent graft for the increasing aneurysm, thereby avoiding a surgical operation. Balloon angioplasty was added for re-stenosis 8 months after the first intervention...

BACKGROUND: Characteristics of a cancer-positive margin around a resected uncinate process of the pancreas (MUP) due to a pancreticoduodenectomy are difficult to understand by standardized evaluation because of its complex anatomy. The purposes of this study were to subclassify the MUP with tissue marking dyes of different colors and to identify the characteristics of sites that showed positivity for cancer cells in patients with pancreatic head carcinoma who underwent circumferential superior mesenteric arterial nerve plexus-preserving pancreaticoduodenectomy...

BACKGROUND: Laparoscopic anti-reflux surgery (LARS) is generally the treatment of choice for patients with gastroesophageal reflux disease (GERD). This report describes our experiences in performing LARS on patients with GERD, and focuses retrospectively on the pathophysiology of individual patients and the current status of Japanese patients who have undergone LARS. We demonstrate that patients with non-erosive reflux disease resistant to proton pump inhibitors (PPI-resistant NERD) and high-risk giant hernia, whom we are sometimes hesitant to treat surgically, can be safely and successfully treated with LARS (depending on the pathophysiology of individual patients)...

The guidelines for the treatment of atopic dermatitis (AD) issued by the Japanese Dermatological Association (JDA), which are basically designed for dermatologists, were first prepared in 2000 and revised in 2016. The guidelines for AD of the Japanese Society of Allergology (JSA), which are basically designed for allergologists, including internists, otorhinolaryngologists, ophthalmologists, and dermatologists, were first prepared in 2009 and revised in 2014. In this article, I review the definition, pathophysiology, etiology, epidemiology, diagnosis, severity classification, examination for diagnosis and severity assessment, and treatments for AD in Japan according to these two guidelines for AD (JDA and JSA)...

BACKGROUND: The healing process of bone fracture requires a well-controlled multistage and sequential order beginning immediately after the injury. However, complications leading to nonunion exist, creating serious problems and costs for patients. Transforming growth factor-beta 1 (TGF-β1) and bone morphogenic protein 2 (BMP-2) are two major growth factors involved in human bone fracture healing by promoting various stages of bone ossification. In this study, we aimed to determine the role of these factors during the fracture healing of human long bones and assess their impacts on nonunion condition...

OBJECTIVE: Asymmetric dimethylarginine (ADMA) is an endogenous nitric oxide synthase inhibitor and a marker of vascular endothelial damage. Angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker (ARB) are reported to reduce the serum ADMA level. Our group administered either ARB or calcium antagonist to patients after cerebral infarction and discussed the ADMA changes observed. METHODS: Hypertensives in the chronic stage of cerebral infarction were enrolled...

BACKGROUND: Infundibular dilatation (ID) is a funnel-shaped enlargement of the origin of cerebral arteries. The coexistence of an aneurysm and ID is relatively rare. Patients with IDs are rarely followed up. However, some IDs have been reported to develop into aneurysms with subsequent rupture. Here we report on a case of an aneurysm that coexisted with ID of the posterior communicating artery. CASE PRESENTATION: A 51-year-old woman underwent magnetic resonance imaging (MRI) to check for aneurysms and other problems...

Epidural analgesia is used to promote rehabilitation in patients with refractory complex regional pain syndrome (CRPS) who cannot bear physical programs due to intense pain. However, the actual rehabilitation process has not been focused in previous reports. Here, we outline our experience of treating a young woman with CRPS type 1 who underwent rehabilitation facilitated by a continuous lumbar epidural block. A 15-year-old girl developed throbbing pain from her left toe to her ankle, with no obvious cause...

Severe trauma injuries, such as open pelvic fractures and degloving injuries, have recently become salvageable. However, extensive soft-tissue defects often remain and can lead to disuse atrophy of the extremities, prolonged hospital stays, and numerous other problems. Such injuries can be easily and effectively treated by a general trauma surgeon performing the pedicled omental flap technique. We report on 2 highly diverse and complicated cases of soft-tissue defect that were both successfully treated with this technique...

BACKGROUND: In decompensated liver cirrhosis, hypoalbuminemia still persists even after they have been treated with branched-chain amino acid (BCAA) granules. We prospectively evaluated whether BCAA enriched nutrient switched from BCAA granules would increase the serum albumin level, and consequently extend the survival time after hepatocellular carcinoma (HCC) treatment. METHODS: This study included 77 patients treated for liver cirrhosis with HCC. After the nutritional assessment, all patients initially received BCAA granules...

BACKGROUND: When percutaneous endoscopic gastrostomy is not feasible, a gastrostomy tube may be inserted for enteral access by a laparoscopic or open technique. The aim of this study was to compare the postoperative pain of laparoscopic versus open gastrostomy in patients with complete obstruction caused by advanced esophageal cancer. METHODS: Fifteen patients who had undergone either a reduced port access laparoscopic gastrostomy/jejunostomy (LGJ, n=7) or open gastrostomy/jejunostomy (OGJ, n=8) between July 2011 and December 2015 were retrospectively studied...

BACKGROUND: The influence of varus insertion of femoral implants in uncemented total hip replacement arthroplasty (THR) remains unclear. Thus, in this study, we retrospectively assessed the clinical impact of uncemented THR with femoral implants that were inserted in varus on the basis of radiological findings. MATERIALS AND METHODS: The study participants included 89 patients who underwent uncemented THR for 106 joints and were followed-up for >3 years. From clinical records, we retrieved Japanese Orthopaedic Association (JOA) pain scores and the range of motion (ROM) of flexion and abduction both preoperatively and at the final follow-up...

Toxic epidermal necrolysis (TEN) is a rare skin condition, most often drug-induced, known for its skin detachment and high mortality. In general, acute TEN is considered a T-cell mediated, type IV hypersensitivity disorder. It mostly results from a cumulative effect of risks from the drug structure, drug metabolism, HLA alleles and T cell clonotypes. However, the precise mechanism of TEN is still unknown. Apoptosis or necroptosis causes keratinocytes to lose their shape and adhesion, and necrosis predominates within a few days...

Pott's puffy tumor is a subperiosteal abscess of the frontal bone with osteomyelitis which has become rare because of the widespread use of antibiotics. Here, we report a case of Pott's puffy tumor in a 46-year-old man who visited the department of dermatology with painful swelling of the forehead. Despite open drainage and oral antibiotic therapy, the symptoms recurred twice in the following month. Computed tomography revealed a fistula of frontal bone. The eventual diagnosis was Pott's puffy tumor. The patient underwent endoscopic surgery at the department of otorhinolaryngology and achieved a complete recovery...

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein...

On the basis of computed tomography (CT) examination, a prosthetic graft infection of very late onset was suspected in a 72-year-old man who had undergone replacement of an bifurcated prosthetic graft 6 years earlier because of an abdominal aortic aneurysm and bilateral common iliac artery aneurysms. Emergency CT-guided needle aspiration was performed, and analysis of directly aspirated fluid confirmed the rapid diagnosis. Instead of conventional emergency surgery, CT-guided catheter drainage was the initial treatment and led to the gradual improvement of symptoms and laboratory data...
