How to perform duodenojejunostomy in addition to Roux-en-Y reconstruction following total gastrectomy to facilitate future duodenal surveillance.

We report two cases of total gastrectomy and Roux-en-Y reconstruction that required future endoscopic surveillance of the duodenum. As such, an additional proximal duodenojejunostomy was fashioned to facilitate endoscopic surveillance.

Prospective evaluation of a closed-incision negative pressure wound therapy system in kidney transplantation and its association with wound complications.

Introduction: Wound complications can cause considerable morbidity in kidney transplantation. Closed-incision negative pressure wound therapy (ciNPWT) systems have been efficacious in reducing wound complications across surgical specialties. The aims of this study were to evaluate the use of ciNPWT, Prevena™, in kidney transplant recipients and to determine any association with wound complications. Material and methods: A single-center, prospective observational cohort study was performed in 2018. A total of 30 consecutive kidney transplant recipients deemed at high risk for wound complications received ciNPWT, and the results were compared to those of a historical cohort of subjects who received conventional dressings. Analysis for recipients with obesity and propensity score matching were performed. Results: In total, 127 subjects were included in the analysis. Of these, 30 received a ciNPWT dressing and were compared with 97 subjects from a non-study historical control group who had conventional dressing. The overall wound complication rate was 21.3% (27/127). There was no reduction in the rate of wound complications with ciNPWT when compared with conventional dressing [23.3% (7/30) and 20.6% (20/97), respectively, p = 0.75]. In the obese subset (BMI ≥30 kg/m2), there was no significant reduction in wound complications [31.1% (5/16) and 36.8% (7/19), respectively, p = 0.73]. Propensity score matching yielded 26 matched pairs with equivalent rates of wound complications (23.1%, 6/26). Conclusion: This is the first reported cohort study evaluating the use of ciNPWT in kidney transplantation. While ciNPWT is safe and well tolerated, it is not associated with a statistically significant reduction in wound complications when compared to conventional dressing. The findings from this study will be used to inform future studies associated with ciNPWT in kidney transplantation.

Sarcopenia impacts perioperative and survival outcomes after esophagectomy for cancer: a multicenter study.

BACKGROUND: The impact of sarcopenia on outcomes after esophagectomy is controversial. Most data are currently derived from Asian populations. This study aimed to correlate sarcopenia to short-term perioperative complication rates and long-term survival and recurrence outcomes. METHODS: A retrospective analysis was performed of patients undergoing esophagectomy for cancer from 3 tertiary referral centers in Australia. Sarcopenia was defined using cutoffs for skeletal muscle index (SMI), assessed on preoperative computed tomography images. Outcomes measured included complications, overall survival (OS), and disease-free survival (DFS). RESULTS: Of 462 patients (78.4% male; median age, 67 years), sarcopenia was evident in 276 (59.7%). Patients with sarcopenia had a higher rate of major (Clavien-Dindo ≥ 3b) complications (27.9% vs 14.5%; P < .001), including higher rates of postoperative cardiac arrythmia (16.3% vs 9.7%; P = .042), pneumonia requiring antibiotics (14.5% vs 9.1%; P = .008), and 30-day mortality (5.1% vs 0%; P = .002). In the sarcopenic group, the median OS was lower (37 months [95% CI, 27.1-46.9] vs 114 months [95% CI, 75.8-152.2]; P < .001), as was the median DFS (27 months [95% CI, 18.9-35.1] vs 77 months [95% CI, 36.4-117.6]; P < .001). Sarcopenia was an independent risk factor for lower survival on multivariate analysis (hazard ratio, 1.688; 95% CI, 1.223-2.329; P = .001). CONCLUSION: Patients with preoperative sarcopenia based on analysis of SMI are at a higher risk of major complications and have inferior survival and oncologic outcomes after esophagectomy for esophageal cancer.

Revision Surgery is Possible in Patients With Previous Bovine Pericardium Inferior Vena Cava Reconstruction: A Case Series and Review of Literature.

There is a paucity of research investigating revision surgery for patients with previous inferior vena cava (IVC) reconstruction using bovine pericardium (BP). To the best of our knowledge, no reports of redo procedures have been published in the medical literature. We describe two cases of redo surgery in patients with previous IVC reconstructions using BP following disease recurrence. The first case underwent resection of the BP graft with a second IVC reconstruction using BP, the second case underwent resection of the BP graft without reconstruction due to extensive thromboses. Neither case experienced perioperative complication or morbidity following their redo procedure, and previous IVC reconstruction with BP did not present significant intraoperative technical challenges. One case showed evidence of endothelialisation of the excised BP graft, however, it was not possible to definitively conclude if endothelialisation was present in the second case. Overall, these cases demonstrate that previous IVC reconstruction using BP should not be considered an absolute contraindication for redo surgery in the context of disease recurrence.

Aberrant Vascular Anatomy During Laparoscopic Cholecystectomy: A Case Report of Double Cystic Artery.

Introduction: Laparoscopic cholecystectomy is the standard surgical procedure for the management of benign gallbladder pathology. Anatomical variation, including aberrant cystic artery, increases the risk of complications during laparoscopic cholecystectomy. Obtaining a critical view of safety is important to avoid major vascular and bile duct injury. Case description: We present a case of aberrant anatomy with two cystic arteries of equal caliber in a 41-year-old female undergoing laparoscopic cholecystectomy for acute cholecystitis. Discussion: This case report aims to emphasize the importance of thorough knowledge of hepatobiliary vascular anatomy, as well as variations beyond the critical view of safety, which will contribute to the safety and success of laparoscopic cholecystectomy.

Bouveret syndrome: two approaches one stone.

Bouveret syndrome is a rare cause of gastric outlet obstruction, a consequence of a large impacted gallstone leading to the formation of a bilioenteric fistula. We present a case of a 79-year-old female who presented with a history of persistent nausea and vomiting. Computed tomography of the abdomen revealed a large gallstone impacted in the second part of the duodenum, complicated by a cholecystoduodenal fistula, leading to gastric outlet obstruction. After nasogastric decompression, the patient underwent an upper gastrointestinal endoscopy and attempted stone retrieval which was unsuccessful. Consequently, she underwent laparotomy, gastrotomy, and extraction of the stone. This case highlights the pitfalls of managing Bouveret syndrome via an endoscopic or an open surgical approach.

To stitch or not to stitch: the skin closure of laparoscopic port sites, a meta-analysis.

BACKGROUND: Previous meta-analyses examining skin closure methods for all surgical wounds have found suture to have significantly decreased rates of wound dehiscence compared to tissue adhesive; however, this was not specific to laparoscopic wounds alone. This study aims to determine the best method of skin closure in patients undergoing laparoscopic abdominopelvic surgery in order to minimize wound complications and pain, while maximize cosmesis, time and cost efficiency. METHODS: A comprehensive search of EMBASE, Medline, Pubmed, and CENTRAL was conducted from inception to 1st May 2020 for randomized controlled trials (RCTs). Two independent reviewers extracted data and assessed risk of bias. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to describe the quality of evidence. Meta-analysis was performed using a random-effects model. A summary relative risk (RR) was calculated for dichotomous outcomes where data could be pooled. (Prospero registration number: CRD42019122639). RESULTS: The literature search identified 11,628 potentially eligible studies. Twelve RCTs met inclusion criteria. There was no difference in wound complications (infection, dehiscence, and drainage) between sutures, tissue adhesives nor adhesive papertape. Low-quality evidence found transcutaneous suture had lower rates of wound complications compared with subcuticular sutures (RR 0.22, 95%: CI 0.05-0.98). There was no evidence of a difference in patient-evaluated cosmesis, prolonged pain, or patient satisfaction between the three groups. Closure with tissue adhesive and adhesive papertape was faster and cheaper than suture. CONCLUSION: Tissue adhesive and adhesive papertape offer safe, cost and time-saving alternatives to closure of laparoscopic port sites compared to suture.

PRehabIlitatiOn with pReoperatIve exercise and educaTion for patients undergoing major abdominal cancer surgerY: protocol for a multicentre randomised controlled TRIAL (PRIORITY TRIAL).

BACKGROUND: Radical surgery is the mainstream treatment for patients presenting with advanced primary or recurrent gastrointestinal cancers; however, the rate of postoperative complications is exceptionally high. The current evidence suggests that improving patients' fitness during the preoperative period may enhance postoperative recovery. Thus, the primary aim of this study is to establish the effectiveness of prehabilitation with a progressive, individualised, preoperative exercise and education program compared to usual care alone in reducing the proportion of patients with postoperative in-hospital complications. The secondary aims are to investigate the effectiveness of the preoperative intervention on reducing the length of intensive care unit and hospital stay, improving quality of life and morbidity, and reducing costs. METHODS: This is a multi-centre, assessor-blinded, pragmatic, comparative, randomised controlled trial. A total of 172 patients undergoing pelvic exenteration, cytoreductive surgery, oesophagectomy, hepatectomy, gastrectomy or pancreatectomy will be recruited. Participants will be randomly allocated to prehabilitation with a preoperative exercise and education program (intervention group), delivered over 4 to 8 weeks before surgery by community physiotherapists/exercise physiologists, or usual care alone (control group). The intervention will comprise 12 to 24 individualised, progressive exercise sessions (including aerobic/anaerobic, resistance, and respiratory exercises), recommendations of home exercises (16 to 32 sessions), and daily incidental physical activity advice. Outcome measures will be collected at baseline, the week prior to surgery, during the hospital stay, and on the day of discharge from hospital, and 1 month and 1 months postoperatively. The primary outcome will be the development of in-hospital complications. Secondary outcomes include the length of intensive care unit and hospital stay, quality of life, postoperative morbidity and costs. DISCUSSION: The successful completion of this trial will provide robust and high-quality evidence on the efficacy of a preoperative community- and home-based exercise and education intervention on important postoperative outcomes of patients undergoing major gastrointestinal cancer surgery. TRIAL REGISTRATION: This trial was registered prospectively with the Australian New Zealand Clinical Trials Registry ( ACTRN12621000617864 ) on 24th May 2021.

Cytomegalovirus adrenalitis mimicking adrenal metastasis in an immunocompetent patient.

The adrenal gland is a common site of metastasis due to its rich blood supply. Adrenalectomy is typical treatment in the management of oligometastatic disease. We present an unexpected finding of cytomegalovirus (CMV)-related adrenalitis mimicking adrenal metastasis. A 54-year-old female was reviewed with a history of BRCA2-mutated, hormone receptor-positive invasive ductal cancer of the right breast diagnosed 12 years prior. Surveillance fluorodeoxyglucose positron emission tomography (FDG-PET) demonstrated a new focus of FDG avidity in the left adrenal gland, for which she underwent adrenalectomy. Histopathology revealed CMV-related adrenalitis in an otherwise immunocompetent patient without history of human immunodeficiency virus (HIV) or other immunocompromise. We describe the first case of CMV adrenalitis in a patient without acquired immunodeficiency syndrome. This case was initially presumed to be adrenal metastasis in the context of disseminated metastatic breast cancer and a PET-avid left adrenal lesion.

Staged versus concurrent native nephrectomy and renal transplantation in patients with autosomal dominant polycystic kidney disease: A systematic review.

BACKGROUND: Patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) frequently undergo native nephrectomy before transplantation. The nephrectomy may be a staged procedure or undertaken simultaneously with transplantation. When performed simultaneously, the transplant procedure is more prolonged, involves a larger operative field and incision. There is also a concern of a greater risk of graft loss with simultaneous nephrectomy and transplantation. Moreover, staged surgery may allow nephrectomy to be performed before immunosuppression introduction via a smaller incision or involving a minimally invasive approach. However, staged nephrectomy may require a period of dialysis not otherwise necessary if a transplant and nephrectomy were simultaneous. Moreover, only a single procedure is needed, implying the avoidance of a prior nephrectomy and its attendant morbidity in a patient with chronic renal insufficiency. To account for these issues, this study aims to compare the cumulative morbidity of two-staged procedures versus a single simultaneous approach in term of morbidity and graft outcomes. OBJECTIVES: This study aims to systematically review the literature to determine whether a staged or simultaneous approach to native nephrectomy in ADPKD is the optimal approach in terms of morbidity and graft outcomes. METHODS: A literature search of MEDLINE and EMBASE was conducted to identify published systematic reviews, randomized control trials, case-controlled studies and case studies. Data comparing outcomes of staged and simultaneous nephrectomy for patients undergoing kidney transplantation was extracted and analyzed. The main outcomes analyzed were length of hospitalization, blood loss, operative time, other early postoperative complications and risk of graft thrombosis. Meta-analysis was conducted where appropriate. RESULTS: Seven retrospective cohort studies were included in the review. There was a total of 385 patients included in the analysis, of whom 273 patients underwent simultaneous native nephrectomy and kidney transplantation. Meta-analysis showed an increased cumulative operative time in staged procedures (RR 1.86；95% CI 0.43-3.29 p = 0.01) and increased risk of blood transfusions (RR 2.69; 95% CI 1.92-3.46 p < 0.00001). For the transplant procedure, there were no significant difference in the length of stay (RR 1.03; 95% CI -2.01-4.14 p = 0.52), major postoperative complications (RR 0.02; 95% CI -0.15-0.10 p = 0.74) and vascular thromboses (RR 1.42 95% CI 0.23-8.59 p = 0.7). CONCLUSION: The results suggest that staged nephrectomy followed by kidney transplantation is associated with a longer cumulative operative time and increased cumulative risk of blood transfusions. There is no evidence to suggest that performing a simultaneous nephrectomy and kidney transplant procedure increases the perioperative mortality rate, major postoperative complication rates or risk of vascular thrombosis.

Catastrophic chemotherapy toxicity leading to diagnosis of Fanconi anaemia due to FANCD1/BRCA2 during adulthood: description of an emerging phenotype.

Fanconi anaemia due to biallelic loss of BRCA2 (Fanconi anaemia subtype D1) is traditionally diagnosed during childhood with cancer rates historically reported as 97% by 5.2 years. This report describes an adult woman with a history of primary ovarian failure, who was diagnosed with gastrointestinal adenocarcinoma and BRCA2-associated Fanconi anaemia at 23 years of age, only after she suffered severe chemotherapy toxicity. The diagnostic challenges include atypical presentation, initial false-negative chromosome fragility testing and variant classification. It highlights gastrointestinal adenocarcinoma as a consideration for adults with biallelic BRCA2 pathogenic variants with implications for surveillance. After over 4 years, the patient has no evidence of gastrointestinal cancer recurrence although the tumour was initially considered only borderline resectable. The use of platinum-based chemotherapy, to which heterozygous BRCA2 carriers are known to respond, may have had a beneficial anticancer effect, but caution is advised given its extreme immediate toxicity at standard dosing. Fanconi anaemia should be considered as a cause for women with primary ovarian failure of unknown cause and referral to cancer genetic services recommended when there is a family history of cancer in the hereditary breast/ovarian cancer spectrum.

Individualised, targeted step count intervention following gastrointestinal cancer surgery: The Fit-4-Home randomised clinical trial.

BACKGROUND: To determine the effectiveness of an individualised, daily targeted step count intervention and usual care compared with usual care alone on improving surgical and patient reported outcomes. METHODS: The Fit-4-Home trial was a pragmatic, randomised controlled trial conducted from April 2019 to February 2021. Patients undergoing elective surgery for liver, stomach or pancreatic cancer in two Australian hospitals were recruited. Participants were randomly allocated to receive an individualised, targeted step count intervention and usual care (intervention) or usual care alone (control). A wearable activity tracker was provided to the intervention group to monitor their daily step count target. Primary outcome was the length of stay in the gastrointestinal ward. Secondary outcomes included postoperative complication rates, discharge destination, quality of life, physical activity, pain, fatigue, distress and hospital re-admission within 30 days. Outcome measures were compared between groups using non-parametric statistics. RESULTS: Of the 96 patients recruited, 47 were randomised to the intervention group and 49 were randomised to the control group. The median (interquartile) length of stay in the ward was 7 days (5.0-13.0) in the intervention group and 7 days (5.0- 12.0) in the control group (p = 0.330). Fatigue scores were worse in the intervention group when compared to control (p = 0.018). No other differences between groups were observed. CONCLUSIONS: An individualised, daily targeted step count intervention and usual care did not confer additional benefits in reducing the length of stay in the ward compared to usual care alone for patients undergoing gastrointestinal cancer surgery. TRIAL REGISTRATION: Registered with the Australia and New Zealand Clinical Trials Registry (ACTRN12619000194167).

Quality of Life Instruments and Trajectories After Pancreatic Cancer Resection: A Systematic Review.

ABSTRACT: This systematic review aimed to investigate the instruments available to measure quality of life (QOL) after pancreatic cancer surgery and to describe short- and long-term QOL outcomes. A comprehensive literature search was completed using PubMed, Embase, and Medline from inception to March 2019. Studies investigating QOL outcomes in patients undergoing pancreatic cancer surgery who were 18 years or older were included. The main outcomes of interest were QOL instruments and short (≤6 months) and long term (>6 months) QOL outcomes. The overarching domains of physical, psychosocial, overall QOL, symptoms, and other were used to summarize QOL outcomes. Thirty-five studies reporting on 3573 patients were included. Fifteen unique QOL instruments were identified, of which 4 were disease-specific instruments. Most of the included studies reported no changes in QOL at short- and long-term follow-ups for the overarching domains. No difference in QOL outcomes was reported between different surgical approaches, except laparoscopic versus open distal pancreatectomy, and pancreaticoduodenectomy versus distal pancreatectomy. There are a wide range of instruments available to measure QOL outcomes in pancreatic cancer surgical patients, although only few are disease-specific. Most of the included studies reported no significant changes in QOL outcomes at short- or long-term follow-ups.

Real world outcomes of neoadjuvant chemotherapy and radiotherapy for borderline resectable pancreatic cancer: a multicentre observational study.

BACKGROUND: Neoadjuvant therapy may increase the likelihood of complete (R0) resection for borderline resectable pancreatic cancer. The optimal approach is unknown and differs amongst treatment centres. METHODS: We identified patients with biopsy-proven borderline resectable pancreatic adenocarcinoma who commenced neoadjuvant therapy between January 2012 and June 2019 at three centres in Sydney, Australia. Patterns of care and outcomes of varying approaches were examined. RESULTS: Forty-eight patients were identified. Median age was 66 years (range: 41-84). Staging included endoscopic ultrasound in 98%, PET-CT scan in 77%, laparoscopy in 46%. Neoadjuvant regimens used were a combination of chemotherapy and chemo-radiation (58%), chemotherapy alone (13%) and chemoradiation alone (29%). Radiologic complete or partial response occurred in 33% and progression in 25%. Complete macroscopic surgical resection was achieved in 50%, and R0 resection in 38%. At median follow-up of 15 months, the 1-year and 2-year overall survival was 75% and 63% respectively, and the 1-year and 2-year progression-free survival was 50% and 29% respectively. Significant predictors of macroscopic resectability were radiologic response (p = 0.005) but not addition of radiotherapy to chemotherapy (OR 0.87, p = 0.81). Predictors of overall survival included baseline Ca19.9 level (p = 0.04) and a trend to the use of systemic chemotherapy (HR 0.51, p = 0.07), but not use of radiotherapy (HR 0.70, p = 0.47). CONCLUSION: There is high variability in staging and neoadjuvant approaches for borderline resectable pancreas cancer. Despite aggressive neoadjuvant therapies, R0 resection and prolonged survival are uncommon. The incremental benefit of neoadjuvant radiotherapy after neoadjuvant chemotherapy was not demonstrated in this observational study.

Perioperative outcomes and survival in elderly patients aged ≥ 75 years undergoing gastrectomy for gastric cancer: an 18-year retrospective analysis in a single Western centre.

PURPOSE: Surgical resection for elderly patients with gastric cancer is controversial. This study aims to evaluate the preoperative features and postoperative short- and long-term outcomes of elderly patients following surgical resection for gastric adenocarcinoma. METHODS: Between January 2000 and May 2018, a total of 177 consecutive patients underwent curative gastrectomy for gastric adenocarcinoma was retrospectively reviewed. Propensity score matching (PSM) analysis was used to balance confounding covariates between the elderly and non-elderly groups. Clinicopathological characteristics, intraoperative characteristics, postoperative complications and long-term survival outcomes including overall survival (OS) and Disease Specific Survival (DSS) were compared and analysed using the Kaplan-Meier log-rank test. Multivariate cox proportional hazards regression analysis of clinicopathological factors influencing survival were evaluated. RESULTS: There were 50 patients in the elderly group (age ≥ 75 years) and 127 patients in the non-elderly group (age < 75 years). Elderly patients had more comorbid conditions (p < 0.001), lower albumin concentration (p = 0.034), lower haemoglobin levels (p = 0.001), and poorer renal function (p = 0.043). TNM stage was similar between both groups (p = 0.174); however, lymphatic invasion (p = 0.006) and lymph node metastasis (p = 0.029) were higher in the elderly group. Elderly patients were much less likely to receive any chemo- (p < 0.001) or radiotherapy treatment (p = 0.007) with surgical treatment. After PSM, there were 50 patients in each group. Elderly patients were more likely to develop complications (Clavien Dindo ≥ 2: 50% vs. 26%, p = 0.003). The most common postoperative complications were pneumonia (12% vs. 6%, p = 0.498) and delirium (10% vs. 0%, p = 0.066). Elderly patients had a longer median length of hospital stay (median (IQR): 15.6(9.5) vs. 11.3 (9.9), p = 0.030). There were no differences in 30-day mortality (elderly vs. non-elderly: 1% vs. 1%, p = 0.988). Before and after PSM, age remains an independent predictor of postoperative complications. Before PSM, the estimated mean OS for the elderly and non-elderly patients were 108 months (95%CI, 72.5-143.5) and 143 months (95%CI, 123.0-163.8), respectively (p = 0.264). After PSM, the estimated mean OS for the elderly and non-elderly patients were 108 months (95%CI, 72.5-143.5) and 140 months (95%CI, 112.1-168.2), respectively, (p = 0.360). Before PSM, the estimated mean DSS for the elderly and non-elderly patients were 94 months (95%CI, 61.9-127.5) and 121 months (95%CI, 100.9-141.0), respectively (p = 0.405). After PSM, the estimated mean DSS for the elderly and non-elderly patients were 94 months (95%CI, 61.9-127.5) and 115 months (95%CI, 87.3-143.3), respectively (p = 0.721). Age was not an independent predictor of mortality following gastrectomy for gastric cancer in both PSM matched and unmatched cohort. CONCLUSION: Chronological age alone is not a contraindication to curative resection of gastric adenocarcinoma in elderly patients with acceptable risk. Whilst age affects perioperative complications, the incidence of postoperative mortality and overall survival were not significantly different between elderly and non-elderly gastric cancer patients treated with curative surgery. Gastrectomy with D2 lymphadenectomy can also be performed in carefully selected elderly patients by surgeons with expertise in gastric resection along with appropriate perioperative management.

Pop goes the tumour! Spontaneous haemorrhage of a hepatocellular carcinoma tumour.

An 84-year-old man presented to a rural hospital in Australia with haemodynamic instability and abdominal pain. Investigation revealed haemorrhage from a lesion in his liver-an incidental finding of a hepatocellular carcinoma. Initial resuscitation and damage control surgery was performed at the peripheral hospital prior to transfer to a tertiary centre 386 km away for the second stage of management. The second stage of management included interventional radiological embolization of the bleeding liver vessel and subsequent resection of the liver tumour. This was all undertaken with new policies in place to limit the spread of infection at the peak of the COVID-19 epidemic.

Comparison of the effect of single vs dual antiplatelet agents on post-operative haemorrhage after renal transplantation: A systematic review and meta-analysis.

OBJECTIVES: A significant proportion of renal transplant patients have cardiovascular comorbidities for which they receive treatment with antiplatelet agents. The aim of this study was to systematically review the current literature reporting perioperative outcomes for patients receiving dual antiplatelet therapy compared to single antiplatelet therapy at the time of kidney transplantation with particular reference to the risks of postoperative haemorrhage. MATERIALS AND METHODS: Embase, Medline and Cochrane databases were utilized to identify articles reporting outcomes of renal transplant recipients on single antiplatelet therapy and dual antiplatelet therapy. These outcomes were compared using a random effects model meta-analysis where appropriate. RESULTS: Six articles were incorporated in the analysis, including 130 receiving dual antiplatelet therapy, and 781 in the single antiplatelet therapy group. There was a significantly higher risk of post-operative haemorrhagic events in the dual antiplatelet therapy group compared to the single antiplatelet therapy group (RR 1.58, 95% CI 1.19-2.09, p = 0.001). Post-operative cardiovascular event rates were similar between both groups in individual studies, although this could not be quantitatively analysed. CONCLUSIONS: The use of dual antiplatelet therapy was associated with a higher risk of post-operative haemorrhage compared to the use of single antiplatelet therapy without increased rates of surgical intervention. However, the use of dual antiplatelet therapy may provide protection from cardiovascular events in an inherently higher risk patient group.

Prophylactic Wound Drainage in Renal Transplant: A Survey of Practice Patterns in Australia and New Zealand.

OBJECTIVES: Drains are used routinely in many centers at the conclusion of kidney transplant, despite a paucity of evidence to guide practice in kidney transplant. Studies have not shown benefit from prophylactic drain placement following other major abdominal and vascular operations, and usage is consequently declining. Our aim was to understand practice patterns and rationale for behavior in drain placement and management in kidney transplant. MATERIALS AND METHODS: We conducted an online survey of surgeons who routinely perform kidney transplants across Australia and New Zealand. RESULTS: The response rate was 66% (43/66). Of respondents, 61% reported routine drain insertion, whereas 21% seldom inserted drains. Concerns about bleeding and anticoagulation (63%) and routine practice (58%) were the dominant reasons for drain insertion. The factors selected as most significant in determining drain removal were both volume and time (44%) and volume alone (33%). A volume of < 50 mL/day (51%) was the most commonly reported threshold for removal. The postoperative period of days 3 to 5 was the most commonly selected time point for drain removal (63%). Seventy-four percent of respondents would consider enrolling their patients in a randomized controlled trial to determine the benefits and harms of drain insertion. CONCLUSIONS: Although drain insertion is a common practice, transplant surgeons in Australia and New Zealand reported sufficient uncertainty concerning the potential benefits and harms to warrant design and conduct of a randomized controlled trial.
