Immunohistochemical evaluation of initial biopsy specimens of rectal cancer with APAF-1, Cox-2 and VEGF may predict tumour response to neoadjuvant therapy in patients with advanced rectal adenocarcinoma. Those with an expected limited response may be considered for other investigational neoadjuvant protocols.

A perforated peptic ulcer in a child is a rare entity. Severe abdominal pain in an ill-appearing child with a rigid abdomen and possibly with signs of shock is the typical presenting feature of this life-threatening complication of peptic ulcer disease. We present a case of a 14.5-year-old adolescent girl who developed abdominal and shoulder pain that resolved after 1 day. She was then completely well for 2 days until the abdominal and shoulder pain recurred. On examination, she appeared well, but in pain. A chest radiograph revealed a large pneumoperitoneum. She underwent emergent laparoscopic omental patch repair of a perforated ulcer on the anterior wall of her stomach. Result of a urea breath test to detect Helicobacter pylori was negative. The differential diagnosis of pneumoperitoneum in children is discussed, as are childhood perforated peptic ulcer in general, and the unique clinical features present in this case in particular.

BACKGROUND: Full-thickness rectal prolapse has a significant negative impact on quality of life. The therapeutic options, specifically in elderly patients, are imperfect. Perineal stapled rectal prolapse resection is a novel operation for treating external rectal prolapse. Long-term follow-up following this procedure is lacking. In our study, we report a long-term follow-up of 30 patients, analyzing the long-term recurrence rate, morbidity, and functional outcome. OBJECTIVE: This study aimed to examine the long-term results of perineal stapled rectal resection in a population unfit for prolonged general anesthesia. DESIGN: This was a cohort study with a prospective follow-up. SETTINGS: This study was conducted at a single tertiary referral center. PATIENTS: Patients undergoing perineal stapled rectal resection from January 2010 to June 2013 were included. INTERVENTIONS: Perineal stapled rectal prolapse resection was performed. MAIN OUTCOME MEASURES: The primary outcome measured was prolapse recurrence. RESULTS: A total of 30 patients underwent the surgical intervention. The median follow-up period was 61 months (range, 37–65). No intraoperative or postoperative complications occurred. Six patients (20%) had recurrent rectal prolapse, and continence was not achieved in any of the patients. Two patients who had recurrence underwent a redo perineal stapled rectal resection. LIMITATIONS: This study was limited by the small cohort of selected patients. CONCLUSIONS: Frail patients that can only endure a short procedure under regional anesthesia should be considered for perineal stapled rectal prolapse resection. The lack of mortality and morbidity, specifically in this population, along with the low long-term recurrence rates, make this a favorable surgical alternative.
