Randomized Controlled Trial Clinical Trial
Phase II trial of radical surgery for locally advanced pelvic neoplasia.
Reported operative mortality and survival rates following total pelvic exenteration (TPE) for recurrent pelvic neoplasia are now as good as those for many primary treatments. The currently accepted primary treatments for these tumours are, however, still either radiotherapy alone or radiotherapy and chemotherapy. The primary aim of this study was to evaluate the safety and tolerability of TPE and secondarily to ascertain survival after TPE. ⋯ The survival and operative mortality rates that are now attainable with TPE are comparable to those achieved with chemoradiotherapy in advanced pelvic neoplasia. TPE should no longer be reserved for salvage therapy and should perhaps be compared with chemoradiotherapy as first-line treatment in a phase III randomized trial in patients with these tumours.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective randomized comparison between pylorus-preserving and standard pancreaticoduodenectomy.
Pancreaticoduodenectomy, with either gastrectomy (Whipple procedure) or pylorus-preserving pancreaticoduodenectomy (PPPD), is a complex procedure. Technical diversity, variation and sampling bias exist among surgeons. Previous reports comparing these two procedures are retrospective and not randomized. These factors should be considered seriously and eliminated in comparisons between the two procedures. ⋯ In this prospective randomized study, both PPPD and the Whipple procedure were associated with low mortality and operative morbidity rates. There was no significant difference between PPPD and Whipple resection in terms of operative mortality and morbidity, operating time, blood loss and blood transfusion. PPPD was associated with more frequent delayed gastric emptying, although study of more patients is needed to confirm this.

Randomized Controlled Trial Clinical Trial
Prospective randomized trial of end-to-end versus side-to-side biliary reconstruction after orthotopic liver transplantation.
Biliary reconstruction is the Achilles heel of liver transplantation. Side-to-side anastomosis of donor and recipient bile duct has been claimed to be superior to end-to-end anastomosis in uncontrolled studies. ⋯ Side-to-side and end-to-end biliary anastomosis at liver transplantation are equally effective.

Randomized Controlled Trial Clinical Trial
Prospective randomized double-blind trial between laparoscopic Nissen fundoplication and anterior partial fundoplication.
In the operative management of gastro-oesophageal reflux, a balance must be achieved between adequate control of reflux and excessive dysphagia. The ideal technique is not known. A randomized study was performed to determine whether laparoscopic anterior fundoplication is associated with a lower incidence of postoperative dysphagia than laparoscopic Nissen fundoplication, while achieving equivalent control of reflux. ⋯ Laparoscopic anterior fundoplication achieved equivalent control of reflux, more physiological postoperative manometry parameters, and an improved clinical outcome at 6 months. Continued follow-up remains necessary to confirm the long-term efficacy of the partial fundoplication procedure.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized comparison of prevertebral and retrosternal gastric tube reconstruction after resection of oesophageal carcinoma.
After potentially curative resection of oesophageal cancer and prevertebral gastric tube reconstruction, approximately one-quarter of patients develop secondary dysphagia due to locoregional recurrence. In half of them dysphagia can be prevented by using an extra-anatomical reconstruction route. The present randomized study was conducted to compare the technical and functional results after prevertebral and retrosternal gastric tube reconstruction. ⋯ After subtotal oesophagectomy retrosternal gastric tube reconstruction can be performed easily and safely, and gives functional results similar to those obtained with prevertebral reconstruction. In patients at high risk for developing secondary malignant dysphagia the extra-anatomical route is the reconstruction of first choice.
