Acute abdominal pain is a common cause for presentation to the emergency room and hospital admission. Many of these patients will undergo exploration for suspected appendicitis, but in 20–35% of cases a normal appendix is found. Because of the limited access provided by the gridiron incision, a definitive diagnosis may not be found. Other patients may be(More)
The complications of open antireflux operations may be reduced by laparoscopic techniques. Fifteen patients of median age 42 (range 16-79) years with gastro-oesophageal reflux underwent laparoscopic fundoplication. Preoperative and postoperative assessment was by clinical scoring, oesophageal pH measurement and manometry. Median (range) operating time was(More)
Background: Direct and capacitive coupling of diathermy current have been reported as causes of occult injury during surgical laparoscopy. Methods: In order to determine the incidence of electrosurgical injury adjacent to metal and plastic cannulas, skin biopsies at 19 port sites used for monopolar electrosurgery were analyzed for coagulative necrosis.(More)
Continued haemorrhage from oesophageal varices despite adequate injection sclerotherapy and tamponade has a high mortality rate. Such patients are usually referred for surgery. Over a 10-year period, 30 patients (21 men and nine women of median age 52 (range 21-70) years) with acute variceal haemorrhage uncontrolled by initial treatment underwent early(More)
INTRODUCTION The use of laparoscopy as a diagnostic and therapeutic tool is being used increasingly in the emergency setting with many of these procedures being performed by trainees. While the incidence of iatrogenic injuries is reported to be low, we present six emergency or expedited cases in which the bladder was perforated by the suprapubic trocar. (More)
Laparoscopic appendicectomy for acute appendicitis has been promulgated in many European countries during the 1980s. The introduction of the microchip camera and visual assistance on a monitor has increased the appeal of laparoscopic appendiceal resection. It carries a unique appeal in that the extent of inflammation and the presence of other pathological(More)
BACKGROUND Dumping syndrome is a recognized complication of various gastric surgical procedures, such as vagotomy, pyloroplasty, and gastrojejunostomy. However, it has not to date been reported following laparoscopic Nissen fundoplication in adults. CASE REPORT We describe the case of a 34-year-old woman who developed late dumping syndrome following an(More)

On examination she was tachycardic with a distended abdomen with left-sided tenderness. On admission her C reactive protein was 77 mg/l, white cell count of 9.9×10l and normal liver function tests. Abdominal plain(More)
Uterine leiomyomas (fibroids) are seen in up to 4% of pregnancies, and most commonly present with pain in pregnancy, which can be due to red degeneration or torsion. Most cases previously have been managed with open resection. We report the case of a 35-y-old primagravida woman, presenting with acute lower abdominal pain at 11 wk gestation. Ultrasound(More)
