Background One of the best sources for high quality information about healthcare interventions is a systematic review. A well-conducted systematic review includes a comprehensive literature search. There is limited empiric evidence to guide the extent of searching, in particular the number of electronic databases that should be searched. We conducted a cross-sectional quantitative analysis to examine the potential impact of selective database searching on results of meta-analyses.

Industry sponsorship has been identified as a source of bias in several fields of medical science. To date, the influence of industry sponsorship in the field of general and abdominal surgery has not been evaluated.A systematic literature search (1985-2014) was performed in the Cochrane Library, MEDLINE, and EMBASE to identify randomized controlled trials in general and abdominal surgery. Information on funding source, outcome, and methodological quality was extracted. Association of industry sp...

Background Incisional hernias are one of the most common long-term complications associated with open abdominal surgery. The aim of this review and meta-analysis was to systematically assess laparoscopic versus open abdominal surgery as a general surgical strategy in all available indications in terms of incisional hernia occurrence.

This systematic review was performed to investigate the ethical justification, methodological quality, validity and safety of placebo controls in randomized placebo-controlled surgical trials. Central, MEDLINE, and EMBASE were systematically searched to identify randomized controlled trials comparing a surgical procedure to a placebo. “Surgical procedure” was defined as a medical procedure involving an incision with instruments. Placebo was defined as a blinded sham operation involving no change...

Aim To examine how effectively forwards citation searching with Web of Science (WOS) or Google Scholar (GS) identified evidence to support public health guidance published by the National Institute for Health and Care Excellence. Method Forwards citation searching was performed using GS on a base set of 46 publications and replicated using WOS. Outcomes WOS and GS were compared in terms of recall; precision; number needed to read (NNR); administrative time and costs; and screening time and costs...

Background Pancreatic cancer is the fourth-leading cause of cancer death for both, men and women. The standard treatment for resectable tumours consists of a classic Whipple (CW) operation or a pylorus-preserving pancreaticoduodenectomy (PPW). It is unclear which of these procedures is more favourable in terms of survival, postoperative mortality, complications, and quality of life. Objectives The objective of this systematic review was to compare the effectiveness of CW and PPW techniques for s...

Background Resections of the pancreatic body and tail reaching to the left of the superior mesenteric vein are defined as distal pancreatectomy. Most distal pancreatectomies are elective treatments for chronic pancreatitis, benign or malignant diseases, and they have high morbidity rates of up to 40%. Pancreatic fistula formation is the main source of postoperative morbidity, associated with numerous further complications. Researchers have proposed several surgical resection and closure techniqu...

Introduction Mesh augmentation seems to reduce recurrences following laparoscopic paraesophageal hernia repair (LPHR). However, there is an uncertain risk of mesh-associated complications. Risk-benefit analysis might solve the dilemma. Materials and Methods A systematic literature search was performed to identify randomized controlled trials (RCTs) and observational clinical studies (OCSs) comparing laparoscopic mesh-augmented hiatoplasty (LMAH) with laparoscopic mesh-free hiatoplasty (LH) with ...

The choice of bibliographic database during the systematic review search process has been an ongoing conversation among information specialists. With newer information sources, such as Google Scholar and clinical trials registries, we were interested in which databases were utilized by information specialists and systematic review researchers.We retrieved 144 systematic reviews and meta-analyses from 4 clinical endocrinology journals and extracted all information sources used during the search p...

Purpose null Patients submitted to curative surgery for non-functioning pancreatic neuroendocrine neoplasms (NF-PanNENs) exhibit a variable risk of disease relapse. Aims of this meta-analysis were to estimate the rate of disease recurrence and to investigate the risk factors for disease relapse in patients submitted to curative surgery for NF-PanNENs. null Methods null Medline/Pubmed and Web of Science databases were searched for relevant studies. A meta-regression analysis was performed to inve...

Background null The exact role of laparoscopic liver resection (LLR) in patients with hepatocellular carcinoma (HCC) and underlying liver cirrhosis (LC) is not well defined. In this meta-analysis, both long- and short-term outcomes following LLR versus open liver resection (OLR) were analysed. null Methods null PubMed, EMBASE, Scopus and Web of Science databases were searched systematically for randomised controlled trials (RCTs) and propensity-score matched (PSM) studies reporting outcomes of L...

PURPOSE Minimally invasive surgery has been universally accepted as a valid option for the treatment of diverticular disease, provided specific expertise is available. Over the last decade, there has been a growing interest in the application of robotic approaches for diverticular disease. We aimed at evaluating whether robotic colectomy may offer some advantages over the laparoscopic approach for surgical treatment of diverticular disease by meta-analyzing the available data from the medical li...

BACKGROUND Minimally invasive oesophagectomy (MIO) for oesophageal cancer may reduce surgical complications compared with open oesophagectomy. MIO is, however, technically challenging and may impair optimal oncological resection. The aim of the present study was to assess if MIO for cancer is beneficial. METHODS A systematic literature search in MEDLINE, Web of Science and CENTRAL was performed and randomized controlled trials (RCTs) comparing MIO with open oesophagectomy were included in a meta...

Historically, invasion of the inferior vena cava (IVC) represented advanced and often unresectable hepatic disease. With surgical and anesthetic innovations, IVC resection and reconstruction have become feasible in selected patients. This review assesses technical variations in reconstructive techniques and post-operative management. A comprehensive literature search was performed according to PRISMA. Inclusion criteria were (i) peer-reviewed articles in English; (ii) at least three cases; (iii)...
