Minimally invasive stomas.

Traditionally, stoma creation and end stoma reversal have been performed via a laparotomy incision. However, in many situations, stoma construction may be safely performed in a minimally invasive nature. This may include a trephine, laparoscopic, or combined approach.

Surgisis mesh repair of a postsacrectomy perineal hernia along with posterior proctosigmoidectomy for concomitant stricture.

Postsacrectomy hernias are uncommon and can present with different signs and symptoms, including constipation, fecal incontinence, bowel obstruction, pain, and posterior bulging. We report a 50-year-old man who underwent sacrectomy for malignant fibrosarcoma complicated with sacral hernia. He presented with obstructive symptoms resulting from a strictured segment of herniated sigmoid colon and underwent bowel resection along with repair of his hernia.

Reoperation for recurrent colorectal cancer.

Recurrence of colorectal carcinoma represents a significant challenge. As the majority of recurrences involve more than just the anastomosis, surgical resection is ordinarily a major undertaking. Curative resection may require resection of other organs and structures, resulting in complex reconstructive procedures and substantial morbidity.

Preventing intra-abdominal adhesions with polylactic acid film: an animal study.

Purpose: The aim of this study was to evaluate the efficacy of an absorbable polylactic acid film (SurgiWrap) in preventing postoperative intra-abdominal adhesions in an animal model.

Methods: Forty-four female Sprague-Dawley rats underwent laparotomy with subsequent cecal wall abrasion and abdominal wall injury. Rats were divided equally between untreated and treated groups.

Primary malignant melanoma of the right colon.

The small and large intestines are the most common sites for metastases from cutaneous malignant melanoma. However, primary melanomas in these sites are exceedingly rare. There are several case reports of patients with primary melanoma of the small bowel, but finding of a solitary primary melanoma in the colon is exceedingly rare.

Colorectal malignancies in HIV-positive patients.

Due to the development of more effective medications, those infected with HIV are living longer. Consequently, more tumors and infections have been added to the AIDS-defining criteria in the last decade. Our aim was to review the occurrence and clinical course of colorectal (CR) malignancies in HIV infected/AIDS patients from a single institution.

Anal trauma and foreign bodies.

Although anal trauma is rare, iatrogenic injury is not uncommon. Immediate recognition is vital to a successful outcome and may obviate the need for a diverting stoma. Evaluation must include a search for involvement of other structures and an evaluation of the anal sphincters.
