Accuracy of intraoperative staging in colorectal cancer.

In 216 patients with colorectal adenocarcinoma 'operative' and 'final' staging using Duke's classification were compared. The overall 'accuracy' of operative staging was 66% with 17% of tumours understaged and 17% overstaged. The major error was found in nodal staging. If selective peroperative adjuvant therapy is to be considered, efforts should be directed to improve operative nodal staging. Any recommendation for adjuvant perioperative chemotherapy based on operative staging alone will result in a significant number of patients having unnecessary treatment.

Some clinical and technical aspects of circular stapled anastomoses of rectum and oesophagus.

A complete 8-year experience using the circular stapling instrument is described; 109 rectal and 59 oesophageal anastomoses were performed. Intra-operative problems included two suspected rectal leaks, damage to the tissues in two patients when using too large an instrument, cardiac arrythmias in one patient, precipitated by contact between the heart and the instrument, one instrument/operator failure, and inversion of the muscle layer was incomplete in three oesophageal anastomoses. Postoperative complications included two leaks, seven strictures, seven abscesses and one patient required reoperation. There were no deaths attributable to the use of the instrument or the method of anastomosis. The instrument has allowed satisfactory anastomoses to be performed in relatively inaccessible sites.

Solitary benign papilloma (papillary adenoma) of the cystic duct: a rare cause of biliary colic.

Benign tumours of the extrahepatic bile ducts are rare, mostly occurring in the common bile duct and hepatic ducts. Solitary papillomas occur mainly in the gallbladder or at the ampulla of Vater. Tumours of the cystic duct are extremely rare, and we are unaware of any reports of solitary papilloma of the cystic duct. Such a case in a 72-year-old woman is presented.
