Review Case Reports
Perforated diverticulum of the caecum. A difficult preoperative diagnosis. Report of 2 cases and review of the literature.
Perforation of a solitary caecal diverticulum is a rare cause of acute abdomen and an uncommon differential diagnosis for acute appendicitis. Nine hundred cases have been described since Potiers' first description of perforated caecal diverticulum in 1912. ⋯ The surgeon must be familiar with the diagnosis and management of this rare, inflammatory benign caecal entity.

The aim of this study was to evaluate operative risk factors, the mortality, morbidity and survival in old patients with colorectal cancer. ⋯ Elderly patients have a lower capacity to react to postoperative complications, but the relative survival is similar to younger patients. Advanced age alone should not be used as a criterion to deny surgery for colorectal cancer.

Persistence of underlying disease in the residual rectal mucosa and anal transition zone (ATZ) following ileal pouch-anal anastomosis (IPAA) for ulcerative colitis and familial adenomatous polyposis provides a site for potential malignancy. For this reason endoscopic surveillance is performed, although conventional assessment may be unreliable. We hypothesized that the novel technique of high-magnification chromoscopic pouchoscopy (HMCP) may permit accurate anatomical localization of this high risk zone in vivo and permit improved biopsy accuracy. ⋯ This is the first study to evaluate this novel application of high magnification chromoscopy. Magnification pouchoscopy is a valid predictor of ATZ and cuff anatomy, permitting accurate biopsy targeting. Further randomized studies validating this technique with an emphasis on dysplasia detection in larger cohorts are required.

Stump appendicitis is a rare clinical situation when there is incomplete appendectomy. A wide spectrum of diseases in the differential diagnosis of right lower quadrant pain of the abdomen and presence of appendectomy operation in a patient's history delay the diagnosis. We report such a case of perforated stump appendicitis and generalized peritonitis occurring eight months after appendectomy.

A 44-year-old man presented with a large and rapidly growing skin lesion approximately six months after resection of a rectal carcinoma. The lesion measured 40 cm in size, extended from the suprapubic area to the proximal half of the left groin, and showed a particular zosteriform aspect. ⋯ Their gross appearance is not distinctive, although the skin tumors are usually solid, small (less than 5 cm) and painless nodules or papules. Early biopsies for suspicious skin lesions are needed in patients with a history of colorectal cancer.
