GIST is the commonest mesenchymal tumour of the gastrointestinal tract. Jejunal GIST is rare and spontaneous perforation of asymptomatic jejunal GIST is unique. A review of the English literature reveals only fifteen cases of perforated GIST till date. Pre-operative diagnosis is difficult. Diagnosis is confirmed on histopathology and immuno-histochemistry. Complete removal with postoperative im...

OBJECTIVE We sought to evaluate the surgical service in the central part of the Eastern Cape Province by reviewing the practice of appendicectomy at Frere Hospital. Specifically, it was our aim to compare the service to those patients who reside in and outside the East London metropolitan area and the outcomes of patients according to their operative finding. PATIENTS AND METHODS A retrospect...

This study aims to investigate a new shear reinforcement method which utilizes thin mild steel (TMS) plates as in deep beams replace conventional reinforcement. Thirteen reinforced concrete beam specimens with three different plate thicknesses and four varying perforated hole arrangements on the TMS were experimentally tested determine load-carrying capacity crack pattern. The experimental resu...

This work describes the in-plane uniaxial tensile mechanical properties of two-dimensional graded rectangular perforations metamaterials using numerical homogenization finite element approaches benchmarked by experimental results. The metamaterial configuration is based on patterns centre-symmetric perforated cells that can exhibit an auxetic (negative Poisson’s ratio) behavior. Global and loca...

background appendicitis is one of the most common causes of mortality, despite medical advances it continues to be a major problem. objectives the main goal of this study was healing initial of appendectomy infection wounds with washing method. patients and methods this study is a semiexperimental investigation which was performed on 300 patients with perforated appendicitis and infected ulcers...

Spontaneous perforation of the uterus is rare, its incidence being about 0.01%-0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of p...

BACKGROUND Clinical characteristics and complications of Duchenne muscular dystrophy caused by skeletal and cardiac muscle degeneration are well known. Gastro-intestinal involvement has also been recognised in these patients. However an acute perforated gastro-duodenal peptic ulcer has not been documented up to now. CASE PRESENTATION A 26-year-old male with Duchenne muscular dystrophy with a ...

We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares connected by small ligaments. Our combined analytical, experimental and numerical results indicate that under uniaxial tension the ligaments buckle out of plane, inducing the formation of 3D patterns whose morphology is controlled by the load direct...

Peptic ulcer is a common disease affecting millions of people every year. Despite improved understanding and treatment of the disease, the number of patients admitted with duodenal peptic ulcer perforation has not decreased. Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simp...

Between January 1968 and December 1977 a total of 230 patients with a perforated duodenal ulcer underwent emergency operation in the Royal Victoria Hospital. Simple suture closure of the perforation was carried out in 205, and in the remaining 25 a definitive ulcer procedure was performed in addition. Four patients died following operation, a mortality rate of 1.7%.During a mean follow-up perio...
