Laparoscopic surgery is one of the most significant surgical advances of the twentieth century. Recently, the focus has been on the development of minimally invasive techniques in the form of single-incision laparoscopic surgery. The single-incision technique provides a less invasive alternative to conventional laparoscopic surgery, requiring only one(More)
INTRODUCTION Single-port/incision laparoscopic appendectomy (SPILA) is a modern advancement toward stealth surgery, using a single point of entry. Despite the paucity of clinical data, it is increasingly being used to minimize scarring and, potentially, pain associated with the multiple entry points. We aimed to summarize and present available data on this(More)
OBJECTIVE To describe the clinical features and cytogenetic analysis of patients with Down syndrome (DS). DESIGN An observational study. PLACE AND DURATION OF STUDY The Departments of Paediatrics and Internal Medicine of Military Hospital, Rawalpindi (MH, RWP) from January 1998 to December 2001. PATIENTS AND METHODS Two hundred and ninety-five(More)
To evaluate the clinical results of the use of biodegradable oesophageal stents in malignant strictures. Eleven patients were included in this prospective analysis in which a woven polydioxanone biodegradable oesophageal stent was used. The inclusion criterion was that the patient underwent neoadjuvant treatment or radical radiotherapy after the stent(More)
INTRODUCTION The traditional management of appendiceal mass has been an initial conservative approach followed by interval appendicectomy. More recently, the necessity of interval appendicectomy has been questioned by a growing amount of evidence in the surgical literature. The aim of this study was to review the available scientific evidence and to(More)
BACKGROUND Appendicectomy is a well established surgical procedure used in the management of acute appendicitis.  The operation can be performed with minimally invasive surgery (laparoscopic) or as an open procedure. A recent development in appendicectomy has been the introduction of less invasive single incision laparoscopic surgery, using a single(More)
BACKGROUND Laparoscopic liver resection is increasingly being used for the excision of benign and malignant hepatic lesions. The aim of this study was to perform meta-analysis on the compiled data from available observational studies. METHODS All the studies comparing laparoscopic versus open liver resections were searched on the available databases. Data(More)
The face of surgery has changed over the past two decades with the introduction of laparoscopic techniques. The majority of surgical specialties now perform minimally invasive procedures hence decreasing the scarring, pain, and infection historically associated with open surgery. To further reduce the invasiveness of surgery, new surgical techniques like(More)
INTRODUCTION Since the introduction of minimally invasive techniques, there is little agreement about use of laparoscopic surgery for malignant liver lesions as compared to open resection. We aim to analyse all available data comparing both these groups. METHODS All the studies that compared laparoscopic and open liver resections for malignant lesions(More)
Surgical smoke containing potentially carcinogenic and irritant chemicals is an inevitable consequence of intraoperative energized dissection. Different energized dissection methods have not been compared directly in human laparoscopic surgery or against commonly encountered pollutants. This study undertook an analysis of carcinogenic and irritant volatile(More)
