Technical modification to laparoscopic appendectomy.
An alternative technique for laparoscopic appendectomy is described. The isolated appendix is exteriorized through the trocar wound, ligated, and resected. The cecum is then returned to the abdomen.

A descriptive study of emergencies admitted to a surgical department.
A study was undertaken to evaluate the pattern of emergency admissions and their management by the surgical firm in a medium size (700 beds) general hospital. Over a three month period, 258 patients were admitted to one surgical team that was on take every third day. All patients were entered into a protocol that was updated daily by a registrar. In four (13.3%) of the 30 days on take, patients had to be referred to a nearby hospital due to shortage of emergency beds. The accuracy of diagnosis by the Accident and Emergency (A&E) resident, surgical resident and surgical team were 75.7, 77.2 and 88.4% respectively. The mean delay before attendance by an intern after admission was 47 (SD +/- 29) mins. Forty-four (17%) of these admissions were probably unnecessary. A further 22 (8.5%) patients had to be referred to other disciplines, indicating an initial wrong diagnosis. A substantial number of investigations were unnecessarily done on an emergency basis. Ninety-three (36.0%) patients required surgery. The median duration of hospital stay was three days. The overall morbidity was 4.2% and mortality 1.2%. The study was valuable in revealing the deficiencies in the existing emergency service; leading to new proposals to achieve our ultimate aim of providing high quality patient care.

The surgical treatment of multiple small bowel strictures in Crohn's disease by combined resection and stricturoplasty.
Crohn's disease is extremely rare among Asians. Resection of strictures causing obstruction has traditionally been the accepted choice in surgical therapy. This may lead to problems such as iatrogenic short bowel syndrome and its sequelae. Stricturoplasty is an acceptable and safe alternative. We report a case where combined stricturoplasty and resection was performed safely and advocate its use.

The technique of laparoscopic Billroth II gastrectomy.
This report describes the technique of totally intra-abdominal Billroth II gastrectomy. Because the procedure is minimally invasive, patient recovery is remarkable compared with the conventional open technique. The development of this procedure completes the minimally invasive revolution in the management of peptic ulcer disease, which began with the introduction of laparoscopic vagotomy.

Laparoscopic posterior truncal vagotomy and anterior highly selective vagotomy--a case report.
Laparoscopic vagotomy provides a viable alternative to expensive long-term treatment with H2 antagonists in patients with intractable peptic ulcer disease. The minimally invasive procedure offers reduced postoperative discomfort and improved cosmesis. Here, we report our first case of a posterior truncal vagotomy and anterior highly selective vagotomy performed laparoscopically for the first time in Asia. The surgery was uneventful. Diet was resumed on day 3 and the patient was discharged on day 4. Post-vagotomy acid secretion tests on the third week revealed a dramatic decrease in acid production. With further experience, laparoscopic vagotomy can be an attractive alternative to long term medication in peptic ulcer disease.

Combined resection of hepatoblastoma and intracaval right atrial extension with profound hypothermia and circulatory arrest.
Hepatoblastoma is an uncommon liver neoplasm in children but its intraatrial extension through the inferior vena cava is extremely rare. The case described is a 3-year-old boy in whom profound hypothermia and circulatory arrest were used to resect a hepatoblastoma and its extension to the right atrium. This technique allows maximal resection and relief of venous obstruction from atrial extension of hepatoblastoma.

Endoscopic management of bleeding peptic ulcers in Singapore: a multimodality approach.
Endoscopic haemostasis is becoming increasingly important in the management of bleeding peptic ulcers. In this study, rather than being confined to one modality of treatment, the endoscopist was allowed to customize the treatment according to the configuration of the ulcer, accessibility, and rate of bleeding in any particular patient. Fifty patients with actively bleeding peptic ulcers or stigmata of recent haemorrhage were treated endoscopically. Initial haemostasis was achieved in 48 (96%) patients. Eleven patients rebled of whom eight underwent repeat endoscopic treatment. Of these eight patients, three rebled of whom two required surgery. Permanent haemostasis was achieved in 43 of 50 patients (86%). The rate of surgery in the endoscopically treated group was 10%. There was one death due to causes not related to bleeding. The multimodality approach is a useful method of treatment in bleeding peptic ulcers, giving flexibility to the endoscopist in deciding on the best way to deal with the problem.

Cystic duplication of the caecum mimicking intussusception.
Diagnosis of gut duplications are often only made intraoperatively as they are uncommon and do not feature strongly in the differential diagnoses. A case of caecal cystic duplication mimicking intussusception is discussed with the aim of improving diagnostic accuracy in future cases. A 7 month old boy presented with the classical triad of abdominal pain, bleeding per rectum and a palpable mass. Barium enema revealed a mass in the caecum suggestive of an intussusceptum. Repeated attempts at hydrostatic reduction were unsuccessful as the mass was immobile. Laparotomy revealed cystic duplication of the caecum without intussusception. The bleeding per rectum was due to an ulcer in the colonic epithelium overlying the cyst.

A multimodality approach to endoscopic treatment of bleeding peptic ulcers.
The role of endoscopic haemostasis in the treatment of bleeding peptic ulcers is widely studied. Many trials to date have compared one or more modalities against a medical control with variable results. To date, no single modality has been shown conclusively to be superior to others. As such, in this study we have not confined the endoscopist to one modality of treatment but allowed him to customize the method of endoscopic haemostasis according to the configuration, accessibility and rate of bleeding in any particular patient. Seventy-three patients with non-variceal upper gastrointestinal (GI) bleeding were admitted to the National University Hospital in Singapore between May 1, 1988 and April 30, 1989. All were gastroscoped and 48 were found to have chronic peptic ulcer. Twenty-nine (60%) with actively bleeding peptic ulcer or stigmata of recent haemorrhage (SRH) were treated endoscopically. Initial haemostasis was achieved in 27 (93%) patients. Seven patients rebled (26%) of which four underwent repeat endoscopic treatment. Of these four patients only one rebled again and required surgery. Permanent haemostasis was achieved in 23 of 29 patients (79%). The multimodality approach for the treatment of bleeding peptic ulcers gives the endoscopist flexibility in deciding on the best way to deal with a bleeding gastric or duodenal ulcer. Each instrument has its strengths and weaknesses and the right choice of instrument is often a critical factor especially in treating a bleeding ulcer in a situation where access poses a problem.

Traumatic posterior dislocation of the hip--a local experience and review of the literature.
The results of 30 patients who sustained traumatic posterior dislocation of the hip treated in both Departments of Orthopaedic Surgery in the Singapore General Hospital from January 1980 to May 1987 were analysed. The most common cause was motorcycle accidents. Young adult males formed the majority of affected cases. 90% of the dislocations were of the Types I and II. Associated injuries were common. The primary treatment was closed reduction under anaesthesia. The subsequent period of traction and non-weight bearing was variable, but it did not seem to affect the final results. Avascular necrosis of the femoral head and secondary osteoarthritis were the major complications. The overall functional results were good.
