Quantification of fluoroscopic fundoplication anatomy: inter- and intraobserver reliability.

The etiology of postfundoplication dysphagia remains incompletely understood. Subtle changes of gastroesophageal junction (GEJ) anatomy may be contributory. Barium swallows have potential for standardization to evaluate postsurgical anatomical features. Using structured barium swallows, we aim to identify reproducible, objectively measured postfundoplication anatomical features that will permit future comparison between patients with/without dysphagia. At 6-12 months of postfundoplication, 31 patients underwent structured barium swallow with video-fluoroscopy recording: standing anteroposterior; standing oblique (×2); prone oblique (×2); and prone oblique with continuous free drinking. A primary observer recorded 11 variables of GEJ anatomy for each view, repeated 3 months later, forming two datasets to assess intraobserver consistency. Interobserver reliability was determined using a dataset each from the primary observer and two medical students (after training). Intraclass correlation coefficients (ICC) were based on two-way mixed-effects model (ICC agreement: 0.40-0.59 'fair'; 0.60-0.74 'good'; 0.75-1.00 'excellent'). Interobserver reliability was good-excellent for 47 of 66 measurements. Measures of maximal esophageal diameter cf. wrap opening diameter and posterior esophageal angle showed high interobserver reproducibility on all views (ICC range 0.84-0.91; 0.68-0.80, respectively). Interobserver agreement was good-excellent for 5/6 views when measuring anterior GEJ displacement and axis deviation (ICC range 0.56-0.79; 0.41-0.77, respectively). Measures of wrap length showed lower reproducibility. Prone oblique measurements showed highest reproducibility (good-excellent agreement in 19/22 measurements). Intraobserver consistency was excellent for 98% of measurements (ICC range 0.74-0.99). Objective measurements of postfundoplication GEJ anatomy using structured barium swallow are reproducible and may allow further interrogation of anatomical features contributing to postfundoplication dysphagia.

Quality and outcomes of synchronous two-team Ivor-Lewis oesophagectomy: Revisiting a variant technique.

BACKGROUND AND OBJECTIVES: In 1975, a modification of popular two-stage Ivor-Lewis oesophagectomy was published with synchronous resection in chest and abdomen. As data on this technique are rare and inconsistent, we aimed to investigate safety, feasibility, and outcome of this approach. METHODS: Outcome of 201 patients undergoing synchronous oesophagectomy from 2000 to 2013 was analysed retrospectively. Two groups (early: 2000-2006; late: 2007-2013) were analysed to allow comparison of outcome over time. RESULTS: Patients in the later period had fewer respiratory comorbidities (P = 0.010), median blood loss decreased significantly over time while lymph node yield increased (P < 0.001). Overall complications occurred in 58.9 (early) versus 51.7% (late) of patients (P = 0.320), anastomotic leaks in 14.3 versus 6.7% (P = 0.112), respiratory complications in 48.2 versus 34.8% (P = 0.063). Thirty-day/90-day mortality was 2.7% versus 3.4, respectively, 8.1% versus 6.8% (P ≤ 0.793). Long-term survival was better in the later cohort (P = 0.004). CONCLUSIONS: Our data of 201 patients over a period of 14 years suggests that this technique is a quick, feasible, safe, and reasonable alternative to standard two-stage Ivor-Lewis oesophagectomy. Quality of this approach and ultimate outcomes have improved over time, with similar complication rates/outcomes to literature accepted standards for two-stage approach, especially in the later time period.

Once in a Bile - the Incidence of Bile Reflux Post-Bariatric Surgery.

PURPOSE: Excellent metabolic improvement following one anastomosis gastric bypass (OAGB) remains compromised by the risk of esophageal bile reflux and theoretical carcinogenic potential. No 'gold standard' investigation exists for esophageal bile reflux, with diverse methods employed in the few studies evaluating it post-obesity surgery. As such, data on the incidence and severity of esophageal bile reflux is limited, with comparative studies lacking. This study aims to use specifically tailored biliary scintigraphy and upper gastrointestinal endoscopy protocols to evaluate esophageal bile reflux after OAGB, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). METHODS: Fifty-eight participants underwent OAGB (20), SG (15) or RYGB (23) between November 2018 and July 2020. Pre-operative reflux symptom assessment and gastroscopy were performed and repeated post-operatively at 6 months along with biliary scintigraphy. RESULTS: Gastric reflux of bile was identified by biliary scintigraphy in 14 OAGB (70%), one RYGB (5%) and four SG participants (31%), with a mean of 2.9% (SD 1.5) reflux (% of total radioactivity). One participant (OAGB) demonstrated esophageal bile reflux. De novo macro- or microscopic gastroesophagitis occurred in 11 OAGB (58%), 8 SG (57%) and 7 RYGB (30%) participants. Thirteen participants had worsened reflux symptoms post-operatively (OAGB, 4; SG, 7; RYGB, 2). Scintigraphic esophageal bile reflux bore no statistical association with de novo gastroesophagitis or reflux symptoms. CONCLUSION: Despite high incidence of gastric bile reflux post-OAGB, esophageal bile reflux is rare. With scarce literature of tumour development post-OAGB, frequent low-volume gastric bile reflux likely bears little clinical consequence; however, longer-term studies are needed.

HIDA and Seek: Challenges of Scintigraphy to Diagnose Bile Reflux Post-Bariatric Surgery.

INTRODUCTION: Oesophageal bile reflux after bariatric surgery may trigger development of Barrett's oesophagus. Gastro-oesophageal reflux of bile is captured by hepatobiliary iminodiacetic acid (HIDA) scintigraphy; however, anatomical and physiological changes after bariatric surgery warrant protocol modifications to optimise bile reflux detection. METHODS: HIDA scintigraphy occurred 6 months after either sleeve gastrectomy, Roux-en-Y gastric bypass or one-anastomosis gastric bypass. Standard HIDA scanning involves (i) 6-h fast and 24-h abstinence from opioids; (ii) IV administration of 99mTc di-isopropyl iminodiacetic acid; and (iii) dual anterior/posterior 60-min dynamic scanning of the duodenum, stomach and oesophagus. Three challenges were identified, and modifications were implemented, namely, (1) anatomical localisation of refluxed bile on planar scintigraphy was improved by adding a SPECT/CT for 3D imaging; (2) impaired cholecystokinin-controlled gallbladder emptying, following bypassed duodenum, was addressed by ingestion of a 'fatty meal'; and (3) intestinal hypomotility after gastric bypass was counteracted by longer scan duration (75-90 min) to allow bile to pass beyond the gastro-jejunal anastomosis. RESULTS: HIDA scan was undertaken in 18 patients, 13 of whom underwent the modified protocol. The tailored protocol ameliorated issues identified with the standard HIDA scan protocol; thus, accurate anatomical localisation was achieved in all patients, no delayed gallbladder emptying was observed, and bile was observed beyond the gastro-jejunal anastomosis in all gastric bypass patients. The modified technique was well tolerated by patients. CONCLUSION: A tailored HIDA scan protocol with addition of a SPECT-CT scan, ingestion of a fatty meal and prolonged scanning duration results in enhanced bile reflux detection in post-bariatric surgical patients.

Emergency management of massive haemoptysis.

In this manuscript, we present a rare case of massive haemoptysis secondary to rupture of a pulmonary artery aneurysm, which was unusual for having occurred in the absence of tuberculosis or a vasculitis. We describe the emergency management of this that ultimately resulted in the patient's survival from both an anaesthetic and surgical perspective, as well as discuss the role of interventional radiology in this situation.

Effectiveness and safety of inpatient versus extended venous thromboembolism (VTE) prophylaxis with heparin following major pelvic surgery for malignancy: protocol for a systematic review.

BACKGROUND: Venous thromboembolism (VTE) is a common postoperative complication associated with significant morbidity and mortality. The use of prophylactic heparin postoperatively reduces this risk, and the use of extended duration prophylaxis is becoming increasingly common. Malignancy and pelvic surgery both independently further increase the risk of postoperative VTE and patients undergoing major pelvic surgery for malignancy are at particularly high risk of VTE. However, the optimum duration of prophylaxis specifically in this population currently remains unclear. METHODS: We will conduct a systematic review of literature in accordance with the Cochrane Handbook for Systematic Reviews of Interventions (Higgins JPT, Green S. Cochrane Handbook for Systematic Reviews of Interventions version 5.1.0.,2011) to evaluate current evidence of the effectiveness and safety of inpatient versus extended VTE prophylaxis with heparin (all forms) following major pelvic surgery for malignancy. We will search PubMed, EMBASE, and the Cochrane Library. Regarding safety, Food and Drug Administration (FDA), and Therapeutic Goods Administration (TGA) websites will be searched, including all levels of evidence. Results will be the postoperative timeframe in which a VTE event can be considered to have been provoked by the surgery, and the number of patients needed to treat with both inpatient and extended prophylaxis to prevent a VTE event in this timeframe, comparing these to determine if there is a significant benefit from extended prophylaxis. DISCUSSION: This systematic review will aim to identify the postoperative period in which patients undergoing major pelvic surgery for malignancy are at further increased risk of VTE as a result of their surgery and the optimum duration of heparin VTE prophylaxis with heparin to reduce this risk. Determining this will allow evidence-based recommendations to be made for the optimum duration of heparin VTE prophylaxis post major pelvic surgery for malignancy, leading to improved standards of care that are consistent between different providers and institutions. SYSTEMATIC REVIEW REGISTRATION: In accordance with guidelines, our systematic review was submitted to PROSPERO for consideration of registration on 16/12/17 and was registered on 12/1/18 with the registration number CRD42018068961 , and it was last updated on December 1, 2018.

Gas in gallbladder-gallstone ileus?

Gallstone ileus is an uncommon presentation among acute surgical patients. Its diagnosis is often delayed due to its non-specific clinical presentation. We report the case of an 81-year-old gentleman with a 2-day history of small bowel obstruction (SBO). He had a history of gallstone disease and no past surgical history. Plain abdominal radiography was consistent with SBO. A computed tomography (CT) abdomen scan would be warranted given the presentation of SBO in a virgin abdomen. However, this case emphasizes the importance of early CT imaging in a case of suspected gallstone ileus given that the diagnosis could not be made on plain abdominal radiography. CT abdomen is superior in detecting small amounts of gas and at discriminating soft tissue density.

Intrabilary obstruction by colorectal metastases.

Intrabiliary colorectal metastases are rare. We present a case of an 84-year-old man who developed obstructive jaundice secondary to intrabiliary growth of colorectal metastases. The patient presented with three weeks of jaundice and significant weight loss in the preceding months. The patient's background included metastatic colorectal carcinoma, with a previous right hemicolectomy and left hepatectomy for liver metastases. A MRCP showed an obstruction of the biliary tract transitioning at the ampulla. Histology confirmed a malignant adenocarcinoma. When compared to the patient's previous resected colorectal liver metastases, morphology and immunohistochemistry was consistent with colorectal metastases. This case highlights the importance of differentiating a new intraductal papillary neoplasm from a colorectal metastasis. Correctly identifying these lesions requires the use of MRCP and ERCP, as well as immunohistochemistry. This is a priority for clinicians to ensure appropriate therapy.

Detecting Bile Reflux-the Enigma of Bariatric Surgery.

Duodeno-gastro-esophageal reflux, or bile reflux, is a condition for which there is no diagnostic gold standard, and it remains controversial in terms of carcinoma risk. This is pertinent in the context of an increasingly overweight population who are undergoing weight-loss operations that theoretically further increase the risk of bile reflux. This article reviews investigations for bile reflux based on efficacy, patient tolerability, cost, and infrastructure requirements. At this time, whilst no gold standard exists, hepatobiliary scintigraphy is the least invasive investigation with good-patient tolerability, sensitivity, and reproducibility to be considered first-line for diagnosis of bile reflux. This review will guide clinicians investigating bile reflux.

An unexpected diagnosis of primary omental endometrial stromal sarcoma in a patient with acute right abdominal pain: A case report and review of literature.

INTRODUCTION: Extrauterine Endometrial Stromal Sarcoma (EESS) is an extremely rare mesenchymal tumour that simulates other pathologies, and therefore poses a diagnostic challenge. This report outlines a case of EESS arising from the greater omentum mimicking a colonic tumour, with review of literature. PRESENTATION OF CASE: A 47-year-old woman, with history of hysterectomy for menorrhagia and hormone replacement therapy (HRT), presented with right sided abdominal pain and localized peritonism. On exploratory laparoscopy an omental tumour, suspected to arise from the transverse colon was identified and biopsied. The histological features suggested an EESS. Colonoscopy ruled out colonic lesion. A laparoscopic tumour resection and bilateral salpingo-oophorectomy (BSO) was performed. Immunohistochemistry confirmed the diagnosis. No additional lesions or associated endometriosis were found. Resection was followed by adjuvant medroxyprogesterone-acetate therapy. DISCUSSION: We reviewed 20 cases of EESS originating from extragenital abdominopelvic organs reported since 1990. Acute presentation is rare, as well as upper abdominal occurrence. Isolated omental involvement was previously reported in only one case. Endometriosis is a risk factor for development of EESS and history and/or histological evidence for endometriosis is usually present. HRT is another acknowledged risk factor, mostly on the background of endometriosis. To our knowledge, this is the only report of EESS occurring in a woman on HRT treatment without background of endometriosis. CONCLUSION: EESS can occur without endometriosis and HRT may be an aetiological factor. The condition can mimic a chronic or acute abdominal pathology and laparoscopic core biopsy is the best way to achieve a diagnosis and formulate management.

Toward a skin-material interface with vacuum-integrated capped macroporous scaffolds.

Avulsion, epidermal marsupialization, and infection cause failure at the skin-material interface. A robust interface would permit implantable robotics, prosthetics, and other medical devices; reconstruction of surgical defects, and long-term access to blood vessels and body cavities. Torus-shaped cap-scaffold structures were designed to work in conjunction with negative pressure to address the three causes of failure. Six wounds were made on the backs of each of four 3-month old pigs. Four unmodified (no caps) scaffolds were implanted along with 20 cap-scaffolds. Collagen type 4 was attached to 21 implants. Negative pressure then was applied. Structures were explanted and assessed histologically at day 7 and day 28. At day 28, there was close tissue apposition to scaffolds, without detectable reactions from defensive or interfering cells. Three cap-scaffolds explanted at day 28 showed likely attachment of epidermis to the cap or cap-scaffold junction, without deeper marsupialization. The combination of toric-shaped cap-scaffolds with negative pressure appears to be an intrinsically biocompatible system, enabling a robust skin-material interface. © 2016 Wiley Periodicals, Inc.

Surface-bound collagen 4 is significantly more stable than collagen 1.

Collagen 1 (C1) is commonly used to improve biological responses to implant surfaces. Here, the stability of C1 was compared with collagen 4 (C4) on a mixed macrodiol polyurethane, both adsorbed and covalently bound via acetaldehyde glow discharge polymerization and reductive amination. Substrate specimens were incubated in solutions of C1 and C4. The strength of conjugation was tested by incubation in 8 M urea followed by enzyme linked immunosorbent assays to measure residual C1 and C4. The basal lamina protein, laminin-332 (L332) was superimposed via adsorption on C4-treated specimens. Keratinocytes were grown on untreated, C1-treated, C4-treated, and C4 + L332-treated specimens, followed by measurement of cell area, proliferation, and focal adhesion density. Adsorbed C4 was shown to be significantly more stable than C1 and covalent conjugation conferred even greater stability, with no degradation of C4 over twenty days in 8 M urea. Cell growth was similar for C1 and C4, with no additional benefit conferred by superimposition of L332. The greater resistance of C4 to degradation may be consequent to cysteine residues and disulphide bonds in its non-collagenous domains. The use of C4 on implants, rather than C1, may improve their long-term stability in tissues. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 105A: 1364-1373, 2017.

Thiol surface functionalization via continuous phase plasma polymerization of allyl mercaptan, with subsequent maleimide-linked conjugation of collagen.

Thiol groups can undergo a large variety of chemical reactions and are used in solution phase to conjugate many bioactive molecules. Previous research on solid substrates with continuous phase glow discharge polymerization of thiol-containing monomers may have been compromised by oxidation. Thiol surface functionalization via glow discharge polymerization has been reported as requiring pulsing. Herein, continuous phase glow discharge polymerization of allyl mercaptan (2-propene-1-thiol) was used to generate significant densities of thiol groups on a mixed macrodiol polyurethane and tantalum. Three general classes of chemistry are used to conjugate proteins to thiol groups, with maleimide linkers being used most commonly. Here the pH specificity of maleimide reactions was used effectively to conjugate surface-bound thiol groups to amine groups in collagen. XPS demonstrated surface-bound thiol groups without evidence of oxidation, along with the subsequent presence of maleimide and collagen. Glow discharge reactor parameters were optimized by testing the resistance of bound collagen to degradation by 8 M urea. The nature of the chemical bonding of collagen to surface thiol groups was effectively assessed by colorimetric assay (ELISA) of residual collagen after incubation in 8 M urea over 8 days and after incubation with keratinocytes over 15 days. The facile creation of useable solid-supported thiol groups via continuous phase glow discharge polymerization of allyl mercaptan opens a route for attaching a vast array of bioactive molecules. © 2016 Wiley Periodicals, Inc.

Preparing surgeons for rural Australia: the RACS Rural Surgical Training Program.

BACKGROUND: The Royal Australasian College of Surgeons' Rural Surgical Training Program (RSTP) ran from 1996 to 2007. As a formal review of the RSTP had never occurred, it remained unknown whether the RSTP had achieved its objectives of training surgeons for and retaining them in practice in rural Australia. METHODS: Sixty-six RSTP fellows and 67 general surgery fellows were asked to complete a survey evaluating factors influencing the decision to pursue a rural surgical career, the influence of the RSTP on subsequent career pathways and the adequacy of the RSTP in preparing its trainees for rural work. RESULTS: Fifty-one out of 66 RSTP fellows were noted to be in practice in metropolitan Australia, with only 15 in rural Australia. Responses obtained revealed rural surgical rotations during training as a major influence in the decision to perform rural work. Thirty out of 35 RSTP participants stated that the RSTP did not influence their subsequent careers. Six out of 15 RSTP respondents responded positively when asked about the adequacy of the RSTP in preparing its trainees for rural work. CONCLUSION: The RSTP largely succeeded in preparing its trainees for rural work, but did not succeed in retaining the majority of its trainees in practice in rural Australia. It appears that targeting doctors at the point of admission to surgical training, in the hope that this would translate into more rural surgeons, did not result in improved retention in rural areas.

Massive pericardial effusion following a laparoscopic adjustable gastric banding.

Laparoscopic adjustable gastric banding (LAGB) is currently the most common bariatric surgical procedure. The most frequent complications of LAGB surgery are pouch dilatation, gastric prolapse, band erosion, stoma obstruction and access-port problems. We report a rare life-threatening case of massive pericardial effusion as a complication of an infected Lap-Band. The management of this condition included subxiphoid pericardial window, removal of the band and later conversion to gastric bypass.

Laparoscopic adjustable gastric banding in the treatment of obesity: a systematic literature review.

BACKGROUND: We attempted to compare the safety and efficacy of laparoscopic adjustable gastric banding with vertical-banded gastroplasty and gastric bypass. Morbid obesity presents a serious health issue for Western countries, with a rising incidence and a strong association with increased mortality and serious comorbidities, such as diabetes, hyperlipidemia, and cardiovascular disease. Unfortunately, conservative treatment options have proven ineffective. Surgical interventions, such as vertical-banded gastroplasty (stomach stapling), Roux-en-Y gastric bypass, and, more recently, laparoscopic gastric banding have been developed with the aim of providing a laparoscopically placed device that is safe and effective in generating substantial weight loss. METHODS: Electronic databases were systematically searched for references relating to obesity surgery by (1) laparoscopic adjustable gastric banding (LAGB), (2) vertical banded gastroplasty (VBG), and (3) Roux-en-Y gastric bypass (RYGB). RESULTS: Only 6 studies reported comparative results for laparoscopic gastric banding and other surgical procedures. One study reported comparative results for all 3 surgical procedures, and this study was only of moderate quality. In total, 64 studies were found that reported results for LAGB and 57 studies reported results on the comparative procedures. LAGB was associated with a mean short-term mortality rate of approximately 0.05% and an overall median morbidity rate of approximately 11.3%, compared with 0.50% and 23.6% for RYGB, and 0.31% and 25.7% for VBG. Overall, all 3 procedures produced considerable weight loss in patients up to 4 years in the case of LAGB (the maximum follow-up available at the time of the review), and more than 10 years in the case of the comparator procedures. CONCLUSIONS: The Australian Safety and Efficacy Register of New Interventional Procedures-Surgical Review Group concluded that the evidence base was of average quality up to 4 years for LAGB. Laparoscopic gastric banding is safer than VBG and RYGB, in terms of short-term mortality rates. LAGB is effective, at least up to 4 years, as are the comparator procedures. Up to 2 years, LAGB results in less weight loss than RYGB; from 2 to 4 years there is no significant difference between LAGB and RYGB, but the quality of data is only moderate. The long-term efficacy of LAGB remains unproven, and evaluation by randomized controlled trials is recommended to define its merits relative to the comparator procedures.

Multicenter, prospective, double-blind, randomized trial of laparoscopic nissen vs anterior 90 degrees partial fundoplication.

HYPOTHESIS: Laparoscopic anterior 90 degrees partial fundoplication for gastroesophageal reflux is associated with a lower incidence of postoperative dysphagia and other adverse effects compared with laparoscopic Nissen fundoplication. DESIGN: A multicenter, prospective, double-blind, randomized controlled trial. SETTING: Nine university teaching hospitals in 6 major cities in Australia and New Zealand. PARTICIPANTS: One hundred twelve patients with proven gastroesophageal reflux disease presenting for laparoscopic fundoplication were randomized to undergo either a Nissen (52 patients) or an anterior 90 degrees partial procedure (60 patients). Patients with esophageal motility disorders, patients requiring a concurrent abdominal procedure, and patients who had undergone previous antireflux surgery were excluded from this study. INTERVENTIONS: Laparoscopic Nissen fundoplication with division of the short gastric vessels or laparoscopic anterior 90 degrees partial fundoplication. MAIN OUTCOME MEASURES: Independent assessment of dysphagia, heartburn, and overall satisfaction 1, 3, and 6 months after surgery using multiple clinical grading systems. Objective measurement of esophageal manometric parameters, esophageal acid exposure, and endoscopic assessment. RESULTS: Postoperative dysphagia, and wind-related adverse effects were less common after a laparoscopic anterior 90 degrees partial fundoplication. Relief of heartburn was better following laparoscopic Nissen fundoplication. Overall satisfaction was better after anterior 90 degrees partial fundoplication. Lower esophageal sphincter pressure, acid exposure, and endoscopy findings were similar for both procedures. CONCLUSIONS: At the 6-month follow-up, laparoscopic anterior 90 degrees culine partial fundoplication is followed by fewer adverse effects than laparoscopic Nissen fundoplication with full fundal mobilization, and it achieves a higher rate of satisfaction with the overall outcome. However, this is offset to some extent by a greater likelihood of recurrent gastroesophageal reflux symptoms.

Computer-based logbook for surgical registrars.

BACKGROUND: The documentation and monitoring of operative experience is an important component of advanced surgical training. The Royal Australasian College of Surgeons (RACS) monitors the adequacy of training by use of the surgical logbook. The logbook has been a paper-based record that does not permit longitudinal evaluation of the progress of an individual trainee or comparison of different surgical units. METHODS: An electronic logbook has been developed in FileMaker Pro version 5.03 (FileMaker, Santa Clara, California, USA). RESULTS: The electronic logbook has been employed for 1 year and has been used on both Windows and Macintosh platforms without difficulty. Appropriate summaries of the training experience were provided for the RACS at the conclusion of each rotation. CONCLUSIONS: The use of a relational database for logbook purposes provides trainees with a convenient and versatile record of their experience while meeting RACS requirements for documentation of surgical experience.

Improvement of respiratory symptoms following laparoscopic Nissen fundoplication.

BACKGROUND: Laparoscopic fundoplication has become the standard of care for the management of symptomatic gastro-oesophageal reflux disease (GORD). Although atypical and respiratory symptoms are frequently described in standard texts in association with reflux, the response of respiratory symptoms to management of GORD has not been extensively studied. METHODS: Herein is reported a prospective series of 29 patients who presented with predominantly respiratory symptoms. Typical and respiratory symptoms were graded according to a standard scale. All patients had preoperative investigations confirming GORD. These patients were treated by a laparoscopic Nissen fundoplication and followed up for a minimum of 14 months (range: 14-48 months). Patients were contacted and interviewed by an independent observer. RESULTS: Conversion to open surgery was necessary in three patients. There were four significant complications. Ultimately control of typical reflux symptoms was achieved in 88%. Cough was completely relieved in 81% and improved in a further 13%. Wheeze and nocturnal bronchospasm was completely relieved in 50% and improved in the balance. Dysphagia remains a significant problem, with only 42% of patients completely free of trouble. CONCLUSIONS: Overall the respiratory symptoms were improved in the majority of patients, with cough responding somewhat better than wheeze. Appropriate patient selection remains the greatest challenge when a patient with cough or wheeze that is considered to be due to GORD is referred for surgery.

Thoracoscopic talc pleurodesis for malignant pleural effusion.

BACKGROUND: Malignant pleural effusion (MPE) is a common and distressing condition at the end of life for many patients with disseminated cancer. The challenge for the surgeon lies in managing this problem in order to deliver the most effective palliation with the least impact on the limited time available to these patients. METHODS: Herein is reported a retrospective review of outcomes for a consecutive series of 66 MPE (61 patients) treated over a 5-year period from 1995 to 2000. A standard operative technique involving a single-lung anaesthetic and two-port thoracoscopy was employed. Outcomes were determined by contacting the referring practitioner or the patients themselves. Principal outcome measures included time to recurrence of the effusion and survival. RESULTS: Complete follow up was achieved for 60 MPE (55 patients; five of whom were treated for metachronous, bilateral disease). The three most common primary sites were breast, lung and mesothelial tissue. The planned procedure was not completed in two cases due to encasement of the underlying lung by tumour. Primary failure (immediate recurrence of the effusion) occurred in six cases. Delayed recurrence of the effusion occurred in a further 23 MPE resulting in complete control in 31 cases (52%) until death. Overall median survival was 220 days and the 30-day mortality was 0. CONCLUSIONS: Complete and permanent control of a malignant effusion is difficult to achieve. Management based on thoracoscopy and talc insufflation produces satisfactory results with an acceptable morbidity and no early mortality. The ability to inspect the pleural space, break down adhesions and completely drain pockets of fluid to achieve complete lung expansion probably contributes to this.
