To compare laparoscopic with open hernia repair in a randomized clinical trial at a median follow-up of 5 years. ⋯ These data show a similar outcome for laparoscopic and open hernia repair, and both procedures have a place in managing this common problem.
-
To audit the results of endoscopic transanal resection of tumor (ETAR) performed by a single surgeon at a specialized colorectal unit during a 10- year period. ⋯ Endoscopic transanal resection of tumor is safe and effective and offers successful palliation or definitive treatment of rectal lesions with low rates of death and complications when performed by a dedicated surgeon.

Randomized Controlled Trial Comparative Study Clinical Trial
Laparoscopic repair for perforated peptic ulcer: a randomized controlled trial.
To compare the results of open versus laparoscopic repair for perforated peptic ulcers. ⋯ Laparoscopic repair of perforated peptic ulcer is a safe and reliable procedure. It was associated with a shorter operating time, less postoperative pain, reduced chest complications, a shorter postoperative hospital stay, and earlier return to normal daily activities than the conventional open repair.

To evaluate the benefit of staging laparoscopy in patients with gallbladder cancer and hilar cholangiocarcinoma. ⋯ Laparoscopy identifies the majority of patients with unresectable hilar cholangiocarcinoma or gallbladder carcinoma, thereby reducing both the incidence of unnecessary laparotomy and the length of stay. The yield of laparoscopy is lower for hilar cholangiocarcinoma but can be improved by targeting patients at higher risk of occult unresectable disease. All patients with potentially resectable primary gallbladder cancer and patients with T2/T3 hilar cholangiocarcinoma should undergo staging laparoscopy before surgical exploration.

To evaluate the pathogenesis of metaplastic processes within the esophagus using a human model in which the exact duration of reflux was known. ⋯ Esophageal columnar metaplasia is a common complication after gastric pull-up esophagectomy. Metaplasia is more likely to develop in patients with previous BE than other patients. Metaplasia develops in response to squamous epithelial injury in predisposed individuals.
