Effect of pyloroplasty on clinical outcomes following esophagectomy.

Introduction: The role of concurrent pyloroplasty with esophagectomy is unclear. Available literature on the impact of pyloroplasty during esophagectomy on complications and weight loss is varied. Data on the need for further pyloric intervention are scarce.

Risk factors for and treatment of anastomotic strictures after Ivor Lewis esophagectomy.

Introduction: Anastomotic strictures following esophagectomy occur frequently and impact on nutrition and quality of life. Although strictures are often attributed to ischemia and anastomotic leaks, the role of anastomosis size and pyloroplasty is not well evaluated. Our study aims to assess the rate of and risk factors for anastomotic stricture following esophagectomy, and the impact of treatment with regular endoscopic balloon dilatations.

Largest sized enterolith ileus due to a duodenal diverticulum in a virgin abdomen causing small bowel obstruction.

We describe the case of a 73-year-old woman with a high body mass index and a virgin abdomen who presented with a 5-day history of abdominal pain, emesis and confusion on admission. Inflammatory markers and renal function were significantly deranged. CT of the abdomen and pelvis demonstrated a clear transition point and faecalisation of the small bowel proximal to the obstruction.

Low grade dysplasia in Barrett's esophagus: Should we worry?

The optimal management for low-grade dysplasia (LGD) in Barrett's esophagus is unclear. In this article the importance of LGD is discussed, including the significant risk of progression to esophageal adenocarcinoma. Endoscopic surveillance is a management option but is plagued by sampling error and issues of suboptimal endoscopy.

Retraction-related liver lobe necrosis after laparoscopic gastric surgery.

Background: Liver retraction is necessary for optimal exposure during laparoscopic gastric surgery. Though transient venous congestion of the retracted lobe of the liver is invariably seen during operations, major parenchymal injury is rare. We describe a case of Nathanson liver retractor-induced left lobe liver necrosis and review the pertinent literature.

Ratio of metastatic lymph nodes to total number of nodes resected is prognostic for survival in esophageal carcinoma.

Introduction: The role of the number of metastatic nodes in esophageal cancer surgery is of interest. We assess predictors of survival after oesophagectomy for esophageal and gastroesophageal junction malignancy.

Methods: Prospective data of consecutive patients undergoing oesophagectomy and systematic lymphadenectomy between 1991 and 2007.

Laparoscopic duodenojejunostomy for the treatment of superior mesenteric artery (SMA) Syndrome: case series.

Superior mesenteric artery (SMA) syndrome is an atypical, rare cause of both acute and chronic high intestinal obstruction. Identification of this syndrome can be a diagnostic dilemma and is frequently made by exclusion. The most characteristic symptoms are postprandial epigastric pain, eructation, fullness, and voluminous vomiting.

Barrett's oesophagus: intestinal metaplasia is not essential for cancer risk.

Objective: Barrett's oesophagus is the main identifiable risk factor for oesophageal adenocarcinoma. It has been suggested that only patients with intestinal metaplasia are at risk of cancer, but the British Society of Gastroenterology (BSG) guidelines suggest that glandular mucosa is all that is needed. The aim of this study was to quantify the risk of adenocarcinoma in columnar-lined lower oesophagus, with or without specialized intestinal metaplasia.

Bilateral ovarian metastases from carcinoma of the gallbladder.

Background: Metastasis of carcinoma of the gallbladder to other intra-abdominal organs is recognised, but is rare. Ovarian metastases can mimic the clinical and morphological appearances of primary ovarian tumours, making the diagnosis difficult particularly when the primary source is not apparent.

Case: A patient presented with abdominal pain and was found to have gallstones and bilateral ovarian masses.

The use of 5-aminolaevulinic acid as a photosensitiser in photodynamic therapy and photodiagnosis.

Photodynamic therapy (PDT) is a treatment for cancer and pre-malignant conditions, which involves the administration of a photosensitising agent followed by exposure of the tissue to light. 5-Aminolaevulinic acid (ALA) is a naturally occurring compound in the haem biosynthetic pathway, which is metabolised to a photosensitive product, protoporphyrin IX (PpIX). The major advantage of ALA when compared to synthetic photosensitisers is the rapid metabolism, which significantly reduces the period of cutaneous photosensitivity.
