Transthoracic Littre's hernia presenting with faecopneumothorax following perforation of the Meckel's diverticulum: a late complication of oesophagectomy.

A Littre's hernia is an unusual phenomenon where a Meckel's diverticulum protrudes through a potential abdominal opening. We wish to present a unique case of a 79-year-old man with respiratory distress following a fall from standing, initially managed as a haemothorax. After a chest drain was placed, bowel contents were drained from the pleural cavity and he was taken to theatre.

Bleeding and hemostasis in laparoscopic liver surgery.

Background: Minimally invasive liver resection is gaining acceptance worldwide. However, the laparoscopic approach often is reserved for small segmental resections due to the fear of significant blood loss. The expansion of laparoscopic liver surgery will depend on the ability of expert surgeons and technological advances to address the management of bleeding and hemostasis with any new approach.

Thoracic splenosis masquerading as bronchial cancer.

A 57-year-old woman presented with adhesional small bowel obstruction and required a laparotomy and adhesiolysis. The postoperative period was complicated by pulmonary embolism. In addition, computed tomography (CT) pulmonary angiogram also demonstrated several indeterminate pleural based pulmonary nodules suspicious of a primary malignancy.

In vivo measurement of 5-aminolaevulinic acid-induced protoporphyrin IX photobleaching: a comparison of red and blue light of various intensities.

Background: In recent years, 5-aminolaevulinic acid (ALA) has become an increasingly popular photosensitizing drug for use in both photodynamic therapy (PDT) and photodetection (PD) of cancers. ALA metabolizes within tissue to form the photosensitizer protoporphyrin IX (PpIX). Like most photosensitizers, PpIX is fluorescent, and this fluorescence progressively decreases during PDT.

Treatment of grade III anal intraepithelial neoplasia with photodynamic therapy: report of a case.

Purpose: We report the use of photodynamic therapy to treat a 53-year-old female with Grade III anal intraepithelial neoplasia.

Methods: Topical 5-aminolevulinic acid cream was applied to the affected area five hours before light treatment. The distribution of 5-aminolevulinic acid-induced protoporphyrin IX was identified by its characteristic red fluorescence.
