Abstract

Hyperbaric oxygenation is achieved when a patient breathes 100 percent oxygen in an environment of elevated atmospheric pressure. Physiologically, this produces a directly proportional increase in the plasma volume fraction of transported oxygen which is readily available for cellular metabolism. A number of beneficial biochemical, cellular and physiologic effects result which account for the use of hyperbaric oxygen as an adjunctive therapy in the treatment of clostridial myonecrosis, crush injuries, compromised flaps, osteoradionecrosis and chronic problem wounds. Indications, modes of treatment, contraindications, side effects, costs and experimental and clinical results are presented. Overall, these data demonstrate that hyperbaric oxygen is no longer "a therapy in search of diseases". However, more randomized controlled clinical trials are necessary to demonstrate its efficacy.

Indications of liver transplantation in patients with complications of cirrhosis.

Transplantation is the only option for reversing liver insufficiency and its complications in patients with end-stage cirrhosis. Transplantation is generally considered after the first episode of decompensation of cirrhosis, provided no specific intervention can result in a longstanding return to the compensated state. Alcohol abuse and hepatitis C virus infection are the predominant causes leading to transplantation in Western countries. In cases of alcoholic cirrhosis, a 6-month period of abstinence is needed before transplantation. Patients with hepatitis C virus infection are considered independent of viral replication, even if post-transplantation recurrence is almost constant. Conversely, in cases of hepatitis B infection, only patients without viral replication (or with extremely low viral load) are suitable candidates. Hepatocellular carcinoma represents an increasing proportion of the indications and offers excellent long-term survival. However, transplantation should be limited to patients with small tumours. HIV infection no longer represents a definitive contraindication.

Severely disordered esophageal peristalsis is not a contraindication to laparoscopic Nissen fundoplication.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) is the preferred operation for the control of gastroesophageal reflux disease (GERD). The use of a full fundoplication for patients with esophageal dysmotility is controversial. Although LNF is known to be superior to a partial wrap for patients with weak peristalsis, its efficacy for patients with severe dysmotility is unknown. We hypothesized that LNF is also acceptable for patients with severe esophageal dysmotility. METHODS: A multicenter retrospective review of consecutive patients with severe esophageal dysmotility who underwent an LNF was performed. Severe dysmotility was defined by manometry showing an esophageal amplitude of 30 mmHg or less and/or 70% or more nonperistaltic esophageal body contractions. RESULTS: In this study, 48 patients with severe esophageal dysmotility underwent LNF. All the patients presented with symptoms of GERD, and 19 (39%) had preoperative dysphagia. A total of 10 patients had impaired esophageal body contractions, whereas 32 patients had an abnormal esophageal amplitude, and 6 patients had both. The average abnormal esophageal amplitude was 24.9 +/- 5.2 mmHg (range, 6.0-30 mmHg). The mean percentage of nonperistaltic esophageal body contractions was 79.4% +/- 8.3% (range, 70-100%). There were no intraoperative complications and no conversions. Postoperatively, early dysphagia occurred in 35 patients (73%). Five patients were treated with esophageal dilation, which was successful in three cases. One patient required a reoperative fundoplication. Overall, persistent dysphagia was found in two patients (4.2%), including one patient with severe preoperative dysphagia, which improved postoperatively. Abnormal peristalsis and/or distal amplitude improved postoperatively in 12 (80%) of retested patients. There were no cases of Barrett's progression to dysplasia or carcinoma. During an average follow-up period of 25.4 months (range, 1-46 months), eight patients (16%) were receiving antireflux medications, with six of these showing normal esophageal pH study results. CONCLUSION: The LNF procedure provides low rates of reflux recurrence with little long-term postoperative dysphagia experienced by patients with severely disordered esophageal peristalsis. Effective fundoplication improved esophageal motility for most of the patients. A 360 degrees fundoplication should not be contraindicated for patients with severe esophageal dysmotility.

An investigation of leakage tracts along stressed suture lines in phantom tissue.

Suturing is still one of the most important procedures used in trauma and surgery environments. It does however rely on piercing other wise healthy tissue. In doing so channels are opened which may act as conduits for bacteria to enter the body or to allow material such as blood or intestinal bacteria to leak from vessels. This work shows by means of finite element analysis and physical modelling through the use of a phantom that the tension in the suture has a direct bearing on the opening of these channels. It was found that for the phantom the channel cross-sectional area was approximately proportional to the applied tension and suture thread deflection. Leakage channels of up to 0.1mm(2) cross-section were achieved with suture tensions of 120 grammes force. Channels of this size are significantly larger than the bacteria suggesting transmission is theoretically possible.
