INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are clinically asymptomatic until they reach a significant size; therefore, GISTs that are 2cm or less are typically asymptomatic. Patients with symptomatic GISTs typically present with abdominal pain, gastrointestinal bleeding, or a palpable mass but rarely present with hemoperitoneum. PRESENTATION OF CASE: A 72-year-old Japanese man presented to us with acute onset abdominal pain. Physical examination showed peritoneal irritation in the lower abdomen...

BACKGROUND: An abdominal aortic aneurysm (AAA) (pathological enlargement of the aorta) is a condition that can occur as a person ages. It is most commonly seen in men older than 65 years of age. Progressive aneurysm enlargement can lead to rupture and massive internal bleeding, which is fatal unless timely repair can be achieved. Despite improvements in perioperative care, mortality remains high (approximately 50%) after conventional open surgical repair. Endovascular aneurysm repair (EVAR), a minimally invasive technique, has been shown to reduce early morbidity and mortality as compared to conventional open surgery for planned AAA repair...

REVIEW
George Pei Cheung Yang
Laparoscopic repair for ventral and incisional hernias was first reported in the early 1990s. It uses intraperitoneal only mesh placement to achieve a tension-free repair of the hernia. However, in recent years, there has been greater concern about long-term complication involving intraperitoneal mesh placement. Many case reports and case series have found evidence of mesh adhesion, mesh fistulation, and mesh migration into hollow organs including the esophagus, small bowel, and large bowel, resulting in various major acute abdominal events...

INTRODUCTION: Trocar dislodgment can occur frequently during minimally invasive surgery. Closing the entry port at the fascial layer after the end of a long laparoscopic surgery is time-consuming. Here, I introduce Tehran's Tie, a simple trick to overcome these problems. MATERIALS AND SURGICAL TECHNIQUE: After the first trocar site has been created with the open technique and before the first port is inserted, the fascial wound is grasped with a loop of nylon thread, similar to a transverse matrix suture...

Iatrogenic nerve palsies due to faulty positioning on the operating table are commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus (BP) is rarely encountered and is a recently reported phenomenon due to the increasing number of complex surgeries including hepatobiliary surgical procedures. Brachial plexus injury (BPI) needs to be recognized as a potential complication of prolonged abdominal surgery. The present case report highlights the potential for BPI and its early recognition, management, and prevention in complex prolonged abdominal surgical procedures...

♦Background: Percutaneous insertion of peritoneal dialysis (PD) catheters by nephrologists is a safe and effective alternative to open surgical techniques. These patients are usually carefully selected due to anatomical considerations and medical comorbidities, with the current literature suggesting exclusion of patients with prior abdominal surgery. ♦ Method: We conducted a retrospective cohort study of pre-dialysis patients who attended a preprocedural clinic in a tertiary center over 6 years. Procedural complications and catheter survival were assessed...

INTRODUCTION: The optimal timing for the closure of loop ileostomies remains controversial. The aim of this study is to determine whether ileostomy closure (<3 months post formation) affects stoma-related morbidity compared to late closure (≥3 months post formation). METHODS: All patients who had loop ileostomy and ileostomy closure between 2012 and 2015 were identified from an IRB-approved, prospectively maintained institutional database.The patients who underwent ileostomy closure (<3 months) were compared against matched patients undergoing ileostomy closure (≥3 months)...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

The stromal vascular cell fraction (SVF) of visceral and subcutaneous adipose tissue (VAT and SAT) has increasingly come into focus in stem cell research, since these compartments represent a rich source of multipotent adipose-derived stem cells (ASCs). ASCs exhibit a self-renewal potential and differentiation capacity. Our aim was to study the different expression of the embryonic stem cell markers NANOG (homeobox protein NANOG), SOX2 (SRY (sex determining region Y)-box 2) and OCT4 (octamer-binding transcription factor 4) and to evaluate if there exists a hierarchal role in this network in ASCs derived from both SAT and VAT...

OBJECTIVE: Although adipose tissue hydrogen peroxide (H2O2) and its metabolizing enzymes have been linked to obesity and insulin resistance in animal studies, this relation remains to be evaluated in humans. METHODS: Non-diabetic men (N = 43, median age, 49 (37, 54 y)) undergoing abdominal surgeries were studied. Participants were classified by body mass index (BMI) into normal-weight (N = 19), or overweight/obese (Ow/Ob; BMI ≥25; N = 24). Centrally obese men were identified by waist-height ratio ≥0...

BACKGROUND: Intraoperative hypercapnia and acidosis are risk factors during thoracoscopy in neonates and infants. METHODS: In a prospective pilot study, we evaluated the effects of thoracoscopy in neonates and infants on cerebral microcirculation, oxygen saturation, and oxygen consumption. Regional cerebral oxygen saturation and blood flow were measured noninvasively using a new device combining laser Doppler flowmetry and white light spectrometry. Additionally, cerebral fractional tissue oxygen extraction and approximated oxygen consumption were calculated...

There is disagreement regarding the benefits of goal-directed therapy in moderate-risk abdominal surgery. Therefore, we tested the hypothesis that the addition of non-invasive cardiac index and pulse pressure variation monitoring to mean arterial pressure-based goal-directed therapy would reduce the incidence of postoperative complications in patients having moderate-risk abdominal surgery. In this pragmatic multicentre randomised controlled trial, we randomly allocated 244 patients by envelope drawing in a 1:1 fashion, stratified per centre...

Mark Scott Johnstone
AIMS: Plastic surgical reconstruction of the perineum is often required after abdominoperineal excision of the rectum. Options for this reconstruction include a vertical rectus abdominis myocutaneous (VRAM) flap, gluteal fasciocutaneous flap, and gracilis myocutaneous flap. Although the VRAM flap is well established at most centers, less experience exists with the gluteal and gracilis flaps. In the era of laparoscopic colorectal resection, plastic surgeons are being forced to use gluteal and gracilis flaps because the VRAM flap must be tunnelled intra-abdominally requiring laparotomy...

Brad Denney, Jorge I de la Torre
Component separation with mesh reinforcement has become the primary modality for complex abdominal wall reconstruction. However, many fundamental questions remain unanswered, such as whether underlay versus overlay mesh placement is superior, and what is the best means of suture fixation technique for mesh placement? This study presents the senior author's technique for onlay biologic mesh placement with multipoint suture fixation in combination with component separation and its subsequent low recurrence rates...

BACKGROUND: Hyperthermic isolated limb perfusion (HILP) represents a limb-sparing treatment for unresectable soft tissue sarcoma (STS) of the extremities with substantial complete response rates. HILP often provides good functional limb preservation, hence a significant improvement also in terms of quality of life of the patient. Notwithstanding these clear advantages, the traditional technique is still hindered by relatively high post-operative morbidity. METHOD: We treated a 78-year-old female with unresectable angiosarcoma of the left leg using a new surgical approach: an entirely laparoscopic HILP...
