Treatment of rectal cancer by chemoradiation followed by surgery: analysis and early clinical outcome in 66 patients.

BACKGROUND: Abdominoperineal resection entails the need for a permanent colostomy, which significantly reduces patient self-image and quality of life. OBJECTIVE: To investigate the effectiveness of preoperative chemoradiation in increasing the resectability rates of rectal cancer and increasing the anal sphincter preservation rate. METHODS: The study group included 66 patients aged 33-84 years with T2-T3 rectal carcinoma who were treated in our institute from 1997 to 2002 with preoperative chemoradiation followed by surgery 6 weeks later. All patients underwent preoperative transrectal endoscopic ultrasound for tumor staging and localization. The duration of follow-up was 25 months. RESULTS: Chemoradiation led to tumor downstaging in 61 patients (92.4%), all of whom underwent low anterior resection. Only 11.4% of this group needed a temporary (6 weeks) loop colostomy/ileostomy. None of the 16 patients with post-treatment T0 tumors had evidence of malignant cells on pathologic study. Five patients (7.6%) failed to respond to chemoradiation and underwent APR. There were no major complications, such as leakage, and no deaths. CONCLUSIONS: Neoadjuvant chemoradiation is an effective modality to downstage advanced rectal cancer, improving patient quality of life by significantly reducing the need for a terminal permanent colostomy, or even a temporary one.

Colonic anastomosis with the nickel-titanium temperature-dependent memory-shape device.

BACKGROUND: This study was prompted by our successful experience with a compression anastomosis clip (CAC) in an animal model. METHODS: The study sample included 20 patients scheduled for colonic resections, of whom 10 underwent anastomosis with the CAC and 10 with staplers. RESULTS: Neither group had anastomotic or other complications, except for 1 patient in the CAC group in whom a subphrenic infected hematoma developed after left hemicolectomy with splenectomy. CONCLUSIONS: Our study demonstrates that this CAC is safe and simple to use, coming close to the "no touch surgery concept" and is of low cost compared with the staples used today.

Percutaneous transhepatic cholecystostomy: effective treatment of acute cholecystitis in high risk patients.

BACKGROUND: The mortality rate for cholecystectomy for acute cholecystitis in the elderly is 10% in low risk patients and increases threefold in high risk patients. Ultrasound-guided percutaneous transhepatic cholecystostomy may serve as a rapid and relatively safe tool to relieve symptoms of sepsis and decrease gallbladder distension. OBJECTIVE: To determine the safety and effectiveness of PTC in the treatment of acute cholecystitis in elderly debilitated high risk patients. METHODS: The study sample included 10 patients aged 63-88 (mean 77.6 years) with clinical and sonographic signs of acute cholecystitis for more than 48 hours (fever, white blood cells > 12,000/mm, positive Murphy sign and distended gallbladder) who underwent ultrasound guided PTC. All had severe underlying disease (coronary heart disease, renal failure, chronic obstructive pulmonary disease, and others) that places them at high risk for surgical intervention. RESULTS: Eight patients showed rapid regression of the clinical symptoms following PTC drainage. One patient with bacterial endocarditis was febrile for 5 days after catheter insertion, but with rapid resolution of the biliary colic and sepsis. One patient died from perforation of the gallbladder and small bowel. PTC catheters were withdrawn 3-25 days after the procedure and the patients remained free of biliary symptoms. Two patients underwent successful elective cholecystectomy 3 weeks later. CONCLUSION: PTC may be a safe and effective treatment for high risk elderly patients with acute cholecystitis. It can be followed by elective cholecystectomy if the underlying condition improves, as soon as the patient stabilizes and no sepsis is present, or by conservative management in high surgical-risk patients.
