Aims Laparoscopic magnetic sphincter augmentation (MSA) or LINX® procedure is gaining popularity as a treatment for gastro-oesophageal reflux disease. We looked at the long-term outcomes of this procedure with regards to its efficacy, in particular studying the dysphagia rate in relation to the LINX® device size. Methods Postal questionnaires were sent to all patients who underwent MSA procedure between 2012-2019 at a single institution. Patients were asked to quantify, as a percentage, their symptom resolution, proton pump inhibitor (PPI) intake and side effects. Results 124 patients (male:female ratio was 45:55) underwent MSA procedure, with 82 responding to the questionnaire. Patients' age range was 18-71 years (median 49). Over 90% of patients reported improvements in reflux symptoms with 75% reporting complete resolution. 67% of patients no longer required PPI medication, whilst 21% of patients had >50% reduction in their medication. Post-operative dysphagia occurred in 59% of patients at 3 months, which decreased to 16% at 1 year. There was no significant difference in size of LINX® device used between patients with dysphagia at ≥ 1 year versus those without dysphagia at ≥ 1 year (p = 0.554). In total 3 patients (2%) required explantation of the LINX® device. Overall 86% of patients rated their outcomes as satisfactory or very satisfactory. Conclusions Our 7 years of experience with laparoscopic MSA has demonstrated that this procedure is safe with high patient satisfaction rates. Dysphagia, although common in the early post-operative period, usually resolves within 3-6 months and is unrelated to LINX® device size.

Most ingested foreign bodies will pass through the gastrointestinal tract without any problems. On the other hand long, slender objects such as a toothbrush will rarely be able to negotiate the angulated and fixed retroperitoneal duodenal loop. Spontaneous toothbrush passage has never been described and therefore endoscopic or surgical removal is always required. Here we describe an asymptomatic young female presenting to out-patient clinic with a history of unintentional toothbrush ingestion 4 yearsprior. Endoscopic removal was unsuccessful because the toothbrush was partially embedded in to the gastric mucosa. We describe the second case to date of laparoscopic removal of a toothbrush via a gastrotomy with subsequent intra-corporeal repair of the defect.Key words: Foreign body, gastronintestinal, laparoscopic, surgery, toothbrush

The aim of this study was to test the hypothesis that gastric bacterial overgrowth is a side effect of acid suppression therapy in patients with gastroesophageal reflux disease (GERD) and that the bacteria-contaminated gastric milieu is responsible for an increased amount of deconjugated bile acids. Thirty patients with GERD who were treated with 40 mg of omeprazole for at least 3 months and 10 patients with GERD who were off medication for at least 2 weeks were studied. At the time of upper endoscopy, 10 ml of gastric fluid was aspirated and analyzed for bacterial growth and bile acids. Bacterial overgrowth was defined by the presence of more than 1000 bacteria/ml. Bile acids were quantified via high-performance liquid chromatography. Eleven of the 30 patients taking omeprazole had bacterial overgrowth compared to one of the 10 control patients. The median pH in the bacteria-positive patients was 5.3 compared to 2.6 in those who were free of bacteria and 3.5 in the control patients who were off medication. Bacterial overgrowth only occurred when the pH was >3.8. The ratio of conjugated to unconjugated bile acids changed from 4:1 in the patients without bacterial overgrowth to 1:3 in those with bacterial growth greater than 1000/ml. Proton pump inhibitor therapy in patients with GERD results in a high prevalence of gastric bacterial overgrowth. The presence of bacterial overgrowth markedly increases the concentration of unconjugated bile acids. These findings may have implications in the pathophysiology of gastroesophageal mucosal injury.

To quantitate and characterize the motility abnormalities present in patients with epiphrenic diverticula and to assess the outcome of surgical treatment undertaken according to these abnormalities.The concept that epiphrenic diverticula are complications of esophageal motility disorders rather than primary anatomic abnormalities is gradually becoming accepted. The inconsistency in identifying motility abnormalities in patients with epiphrenic diverticula is a major obstacle to the general acceptance of this concept.The study population consisted of 21 consecutive patients with epiphrenic diverticula. All patients underwent videoesophagography, upper gastrointestinal endoscopy, and esophageal motility studies. The diverticula ranged in size from 3 to 10 cm and were predominantly right-sided. Seventeen patients underwent transthoracic diverticulectomy or diverticulopexy with esophageal myotomy and an antireflux procedure. The length of the myotomy was determined by the extent of the motility abnormality. Transhiatal esophagectomy was performed in one patient with multiple diverticula. Two patients declined surgical treatment and another patient died of aspiration before surgery. Symptomatic outcome was assessed via a questionnaire at a median of 24 months after surgery.The primary symptoms were dysphagia in 5 (24%) patients, dysphagia and regurgitation in 11 (52%) patients, and pulmonary symptoms in 5 (24%) patients. The median duration of the primary symptoms was 10 years. Esophageal motility abnormalities were identified in all patients. An esophageal motor disorder was diagnosed only by 24-hour ambulatory motility testing in one patient, and 24-hour ambulatory motility testing clarified the motility diagnosis in five other patients. The most common underlying disorder was achalasia, which was detected in nine (43%) patients. A hypertensive lower esophageal sphincter was diagnosed in three patients, diffuse esophageal spasm in five, "nutcracker" esophagus in two, and a nonspecific motor disorder in two patients. One patient had an intraoperative myocardial infarction and died. Two patients had persistent mild dysphagia after surgery. The remaining patients had complete relief of their primary symptoms.There is a high prevalence of named motility disorders in patients with epiphrenic diverticula, and this condition is associated with the potential for lethal aspiration. Twenty-four-hour ambulatory motility testing can be helpful if the results of the stationary examination are normal or indefinite. Resection of the diverticula and a surgical myotomy of the manometrically defined abnormal segment results in relief of symptoms and protection from aspiration.

A female in her sixties presented with recurrent gastrointestinal bleeding over a two-month period requiring multiple hospital admissions. Inconclusive upper and lower gastrointestinal endoscopies in addition to an initial negative CT angiogram initially left the diagnosis uncertain. A subsequent catastrophic bleed prompted a further CT angiogram that demonstrated a fistula between the aorta and third part of the duodenum with active contrast extravasation. Emergency surgery was carried out but ultimately the patient did not survive.

Laparoscopic subtotal cholecystectomy (LSC) is considered to be a safe option in severe cholecystitis with non-discernible anatomy within the Calot’s triangle where there is a potential risk of causing injury to the common bile duct. Here we present two cases of gallstone pancreatitis associated with use of an endoscopic stapler during LSC.
