Rarer complications purchase flomax 0.4 mg without a prescription prostate lymph drainage, such as, vascular or liver injury, pulmonary embolism and bilobed stomach have all been described. Failure of Anti-Reflux Surgery It is difcult to get an accurate estimate of the rates of redo anti-refux sur- gery as most studies are of small volume or from a single centre. Lafullarde published a reoperation rate of >10% in patients who underwent a fun- doplication between 1991 and 1994. Other causes of a poor outcome include failure to recognise delayed gastric emptying; failure to recognise a short oesophagus or wide hiatus; failure to recognise oesophageal dysmotility/endstage refux disease and failure in the technical aspects of the procedure. Common surgical pitfalls include: • The fundus being wrapped around the stomach instead of the oesopha- gus • Incomplete oesophageal mobilisation to obtain a 2–3 cm of abdominal oesophagus • Incomplete mobilisation of the gastric fundus (some cases may neces- sitate division of the short gastric vessels) resulting in a tight fundopli- cation • Incomplete crural closure or tight crural stitches leading to strangulation of the crural muscles (use of pledgets and meshes is advocated by some). Management of Recurrent or Persistent Symptoms After Surgery Patients present with persistent symptoms, recurrent symptoms or new symptoms. Failure to relieve preoperative symptoms is likely due to an initial misdiagnosis. Recurrence of symptoms following an initial relief after surgery suggests the possibility of a disrupted, slipped or herniated fundoplication. New-onset symptoms, like persistent dysphagia, are linked to a tight, misplaced or twisted wrap. To clarify the aetiology an upper gastrointestinal barium study (video fuoroscopy) and endoscopy is essential (Figs. Oesophageal high defnition manometry can help in the diagnosis of a slipped fundopli- cation. Operative times, length of hospital stay and morbidity is greater in revisional surgery compared to the primary procedure. Outcomes of revisional surgery are not as good as the primary procedure with an increased incidence of gas bloat and dysphagia and poorer control of symptoms. A gastropexy to anchor the fundoplication to the crura is occasionally used to minimise the risk of wrap migration. The use of pledget reinforcement to the crural or gastric sutures can help avoid early disruption of the repair. Subsequent randomized trial of the Stretta and sham endoscopy showed no diference at six-month follow-up. In a randomized sham controlled trial, symptom scores improved following the EndoCinch procedure, but the results did not compare well with the outcomes of laparoscopic anti- refux surgery. A sham controlled trial actually showed a signifcant reduc- tion in oesophageal acid exposure from 10% to 7% at three months, but the degree of improvement was inferior to a surgical anti-refux procedure. An endoscope is passed through the device and both are passed transorally into the stomach. A plastic arm then compresses the fundus against the oesophagus and multiple polypropylene fasteners are passed between the oesophagus and the fundus to anchor them together. Fasteners are applied starting from the greater curvature and advancing radially towards the lesser curvature to produce a 200–300° anterior partial fundoplication. Limited published clinical studies suggest that in some patients a fundopli- cation can be constructed. However, the short-term results are still inferior to a laparoscopic fundoplication. It uses a purpose built disposable Chapter 6: Surgical Aspects of Gastro-oesophageal Refux 83 endoscope that contains stapling and ultrasound devices.
