The effect of octreotide on the duration of postmastectomy wound drainage: A randomized controlled trial

Background: Following mastectomy, prolonged wound drainage delays adjuvant therapy and also prolongs hospitalization in an otherwise fit patient. This study determined the effect of octreotide on the duration of postmastectomy wound drainage. Methods: Patients scheduled for modified radical mastectomy were randomized into a treatment group that received 100 µg of octreotide and a control group that received 1 mL of sterile water intravenously 8 hourly for 5 days from the first postoperative day. Sociodemographic data, time to drain removal, total drain volume, and incidence of seroma were obtained. The groups were compared for the time to drain removal, total drain output, average drain output per day, and incidence of seroma. Statistical significance was set at P < 0.05. Results: Forty-one female breast cancer patients were recruited. The mean age was 53.1 ± 13.0 years. The most common histologic variant was invasive carcinoma of no special type (n = 27; 65.9%). Although not statistically significant, patients in the intervention group had a lower median time to drain removal of 11 days (interquartile range [IQR] = 3) compared with 13 days (IQR = 3) in the control group (P = 0.106) and similarly had a lower median total drain output compared with controls (892.0 mL vs. 1182.8 mL; P = 0.095). Both groups were comparable in terms of postoperative complications and these occurred in 13 patients (31.7%), the most common being seroma (n = 11; 50.0%). Conclusion: Octreotide had no statistically significant effect on either the total drain output or the duration of postmastectomy wound drainage among breast cancer patients.

Comprehensive analysis of risk factors for postoperative wound infection following radical mastectomy in breast cancer patients.

Surgical site infections (SSIs) following radical mastectomy in breast cancer patients can significantly affect patient recovery and healthcare resources. Identifying and understanding the risk factors for postoperative wound infections (PWIs) are crucial for improving surgical outcomes. This retrospective study was conducted from June 2020 to June 2023, including 23 breast cancer patients who developed PWIs post-radical mastectomy and a control group of 46 patients without such infections. Comprehensive patient data, including variables such as intraoperative blood loss, hospital stay duration, body mass index (BMI), operation time, anaemia, drainage time, diabetes mellitus, cancer stage, white blood cell (WBC) count, serum albumin levels and preoperative neoadjuvant chemotherapy, were meticulously gathered. Statistical analyses, including univariate and multivariate logistic regression, were performed using SPSS software (Version 27.0). The univariate analysis identified several factors significantly associated with an increased risk of PWIs, including preoperative neoadjuvant chemotherapy, low serum albumin levels, advanced cancer stage, diabetes mellitus and reduced WBC count. Multivariate logistic regression highlighted anaemia, prolonged drainage time, diabetes mellitus, advanced cancer stage, reduced WBC count, hypoalbuminemia and preoperative neoadjuvant chemotherapy as significant contributors to the increased risk of PWIs. Anaemia, extended drainage time, diabetes mellitus, advanced cancer stage, low WBC count, hypoalbuminemia and preoperative neoadjuvant chemotherapy are key risk factors for SSIs post-radical mastectomy. Early identification and proactive management of these factors are imperative to reduce the incidence of postoperative infections and enhance recovery outcomes in breast cancer patients.

Description of a novel robotic early post-prostatectomy anastomotic repair technique and institutional outcomes

ObjectiveA vesicourethral anastomotic leak (VUAL) is a known complication following robotic-assisted radical prostatectomy. The natural history of a VUAL has been well described and is frequently managed with prolonged catheterization. With increasing emphasis on patient reported outcomes, catheter duration and VUAL are associated with significant short-term quality of life impairment. We aimed to present a case series of our robotic early post-prostatectomy anastomotic repair technique, defined as revision within 6 weeks from index surgery. MethodsA single institution prospective database identified eleven patients with a VUAL from July 2016 to October 2022 who underwent robotic early post-prostatectomy anastomotic repair by a single surgeon. Patients were diagnosed with a VUAL on pre-operative CT urogram or CT/fluoroscopic cystogram. The primary outcome was resolution of the anastomotic leak, defined as no contrast extravasation on post-operative cystography. Secondary outcomes included post-repair catheter duration and continence on the last follow-up defined as pad(s) per day. ResultsThe mean time to intervention after robotic-assisted radical prostatectomy was 21 days. Eight of the eleven (72.7%) patients had no evidence of extravasation on post-repair cystogram. The range from intervention to first cystogram was 7–20 days. The median catheter duration for those with successful intervention was 10 days. The median catheter duration for those with the leak on initial post-operative cystogram was 20 days. At a mean follow-up time of 25 months, eight (72.7%) patients reported using no pads per day, and three (27.3%) patients reported one pad per day. ConclusionManagement of a VUAL has traditionally relied on prolonged catheter drainage and the tincture of time. As the role of robotic reconstruction has been shown to be a viable modality for management of bladder neck contracture, it is important to reconsider prior dogmas of urologic care. Our case series suggests that an early repair is safe and has a high success rate. Early robotic intervention gives providers an additional tool in aiding patient recovery.

Evaluation of Perioperative Clinical Parameters and Quality of Life in Patients Undergoing Radical Perineal or Retropubic Prostatectomy: A Prospective Randomized Study

Objective: The objective of study is to investigate the effects of radical retropubic and perineal prostatectomy methods in addition to the effect of pelvic lymph node dissection on perioperative morbidities, oncological outcomes and 1-year quality of life in patients with clinically local stage prostate cancer. Material and methods: Patients admitted to our clinic between January 2013 and March 2015 and diagnosed with clinically localized stage prostate cancer were included. A total of 103 patients were randomized into 3 groups in which 38 patients received radical perineal prostatectomy(RPP), 31 had radical retropubic prostatectomy(RRP), and 34 RRP with pelvic lymph node dissection(PLND). Age, comorbidities, preoperative Gleason scores and serum prostate-specific antigen(PSA) data as well as the surgical parameters, clinical and pathological stages, and 1-year follow-up data were recorded for each patient.“Extended prostate cancer index composite (EPIC)” and “SF-12v2™ Health Survey(Version 2.0)” questionnaires were used for overall and disease-specific quality of life at month 0, 1, 6 and 12 visits. Results: No difference was found between the groups with regard to preoperative data such as age, serum PSA levels, clinical stage, biopsy Gleason score and Charlson comorbidity index while intraoperative data for the amount of bleeding and the average amount of transfusion were significantly lower in RPP group(RPP:645cc, RRP:960cc, RRP+PLND:890cc).1-year recurrencefree survivals for RPP, RRP, and RRP+PLND groups were 9.9 months, 11.2 months and 10.2 months, respectively, with no significant difference.Overall and prostate cancer-specific quality of life was similar for all 3 groups.No additional benefit with nerve-sparing surgery was shown in any of the groups in terms of incontinence and erectile functions. Conclusion: Perineal dissection is beneficial in terms of the amount of bleeding and blood transfusion while prolonged postoperative drainage and wound infection rates are higher compared to retropubic approach.All 3 groups were similar in urinary, sexual, gastrointestinal and hormonal functions as well as the quality of life.

How good are surgeons at disclosing periprosthetic joint infection at the time of revision, based on pre- and intra-operative assessment? A study on 16,922 primary total hip arthroplasties reported to the Norwegian Arthroplasty Register.

Revision due to infection, as reported to the Norwegian Arthroplasty Register (NAR), is a surrogate endpoint to periprosthetic joint infection (PJI). We aimed to find the accuracy of the reported causes of revision after primary total hip arthroplasty (THA) compared with PJI to see how good surgeons were at disclosing infection, based on pre- and intraoperative assessment. We investigated the reasons for revision potentially caused by PJI following primary THA: infection, aseptic loosening, prolonged wound drainage, and pain only, reported to the NAR from surgeons in the region of Western Norway during the period 2010-2020. The electronic patient charts were investigated for information on clinical assessment, treatment, biochemistry, and microbiological findings. PJI was defined in accordance with the Musculoskeletal Infection Society (MSIS) definition. Sensitivity, specificity, and accuracy were calculated. 363 revisions in the NAR were eligible for analyses. Causes of revision were (reported/validated): infection (153/177), aseptic loosening (139/133), prolonged wound drainage (37/13), and pain only (34/40). The sensitivity for reported revision due to infection compared with PJI was 80%, specificity was 94%, and accuracy-the surgeons' ability to disclose PJI or non-septic revision at time of revision-was 87%. The accuracy for the specific revision causes was highest for revision due to aseptic loosening (95%) and pain only (95%), and lowest for revision due to prolonged wound drainage (86%). The accuracy of surgeon-reported revisions due to infection as representing PJI was 87% in the NAR. Our study shows the importance of systematic correction of the reported cause of revision in arthroplasty registers, after results from adequately taken bacterial samples.

Impact of early postoperative haemodynamic and laboratory parameters on outcome after the Fontan procedure.

To identify early postoperative haemodynamic and laboratory parameters predicting outcomes following total cavopulmonary connection. Patients who underwent total cavopulmonary connection between 2012 and 2021 were evaluated. Serial values of mean pulmonary artery pressure, mean arterial pressure, peripheral oxygen saturation, and lactate levels were collected. The influence of these variables on morbidities was analyzed. Cut-off values were calculated using the receiver operating characteristic analysis. A total of 249 patients were included. All patients had previous bidirectional cavopulmonary shunt. Median age and weight at total cavopulmonary connection were 2.2 (1.8-2.7) years and 11.7 (10.7-13.4) kg, respectively. All patients were extubated in the ICU at a median of 3 (2-5) hours after ICU admission. Postoperative pulmonary artery pressure, around 12 hours after extubation, was significantly associated with chest tube drainage (p = 0.048), chylothorax (p = 0.021), ascites (p = 0.016), and adverse events (p = 0.028). Receiver operating characteristic analysis revealed a cut-off value of 13-15 mmHg for chest tube drainage and chylothorax and 17 mmHg for ascites and adverse events. Mean arterial pressure 1 hour after extubation was associated with prolonged chest tube drainage (p = 0.015) and adverse events (p = 0.008). Peripheral oxygen saturation 6 hours after extubation (p = 0.003) was associated with chest tube duration and peripheral oxygen saturation 1 hour after extubation (p < 0.001) was associated with ascites. Lactate levels on 2nd postoperative day (p = 0.022) were associated with ascites and lactate levels on 1st postoperative day (p = 0.009) were associated with adverse events. Higher pulmonary artery pressure, lower mean arterial pressure, lower peripheral oxygen saturation, and higher lactate in early postoperative period, around 12 hours after extubation, predicted in-hospital and post-discharge adverse events following total cavopulmonary connection.

Total Sealing Technique (TST) with a bipolar vessel sealing system reduces lymphorrhea and seroma formation for axillary lymph node dissection in primary breast cancer

BackgroundThe purpose of this study is to evaluate the potential of a novel surgical procedure, the Total Sealing Technique (TST), using the latest bipolar vessel sealing system (BVSS; LigaSure™ Exact Dissector) to reduce lymphatic leakage and seroma formation after electrocautery axillary lymph node dissection (ALND) in breast cancer surgery. Prolonged drainage is a common occurrence after ALND, primarily due to lymphatic leakage. In addition, the presence of seroma often leads to delays in the administration of postoperative adjuvant chemotherapy even after drain removal. MethodsWe conducted a comparative analysis of 36 patients who underwent total mastectomy with ALND using conventional electrocautery technique (CONV) during the first 3 years, and 35 patients who underwent the same procedure using TST during the subsequent 3 years. The following factors were compared to assess the impact of TST: operation time, blood loss, total drainage volume, mean time to drain removal, postoperative hospital stay, mean time to initiation of postoperative chemotherapy, and postoperative complications in each group. ResultsTST significantly reduced drainage volume (360.5 vs. 820.6 mL, p < 0.001), days to drain removal (4.8 vs. 6.8 days, p < 0.001), postoperative hospital stay (5.9 vs. 9.6 days, p < 0.001), the incidence of seroma (28.6 % vs. 65.9 %, p = 0.001), and time to chemotherapy initiation (33.1 vs. 61.4 days, p < 0.001) compared to CONV. ConclusionsTST in total mastectomy with ALND effectively decreases the incidence of lymphorrhea and seroma formation; thus, it can be recommended for total mastectomy with ALND.

Complications of ankle arthroscopy: frequency, prevention, and treatment.

The complication rate of ankle arthroscopy (AA) ranges from 3.5% to 14%. To avoid such complications, it is essential to have a thorough understanding of the anatomy of the ankle, to perform the procedure very carefully and with appropriate instrumentation, and to use a non-invasive distraction technique. The most frequent complications are neurological (cutaneous nerve injuries), which are usually caused by direct injury during arthroscopic portals or by a distracting pin when using an invasive distraction technique. They usually resolve spontaneously within a few months. The iatrogenic formation of a pseudoaneurysm is a severe but extremely rare complication (an incidence of 0.008%). There are several treatments for pseudoaneurysms: external compression; direct thrombin injection, surgical intervention (resection of the damaged segment of the artery and reconstruction with a reversed long saphenous vein interposition graft), and endovascular embolisation. Other rare complications include wound infections (localised superficial infection), problems at the portal incisions (prolonged portal drainage, residual pain in the portal, portal scar dehiscence, cyst at the portal site), type I complex regional pain syndrome, instrument breakage, painful scars and nodules, and a number of other rarer complications. In conclusion, when performing AA, it is important to remember the potential complications and try to avoid them. When they do occur, it is essential to diagnose and treat them appropriately.

Translated article] Wound closure after knee and hip replacement (TKA and THA): Survey results on the clinical practice in Spain

Background and objectiveIn orthopaedic surgery, it is clear that an optimal standardised closure technique has not yet been developed. Locally, there are no objective data describing the standard surgical practice in wound closure. The aim of this study is to analyse the clinical practice of surgical wound closure in orthopaedic surgery by means of a survey of a representative local sample and thus obtain information on the context of closure in Spain. Material and MethodAn ad hoc group of specialists in orthopaedic surgery and traumatology was formed. The group of experts, after analyzing the literature, developed a questionnaire of 32 closed multiple-choice questions divided into the following blocks: hemostasis, surgical wound closure (deep, superficial, and cutaneous), and dressings. ResultsA total of 471 surgeons responded to the survey completely and with sufficient information to perform the descriptive analysis. 79% believe that ATX can influence the decrease in surgical site infection rate. 96% believe that the type of deep closure at the level of the arthrotomy could influence outcomes and complications after hip and/or knee replacements. 85% believe that the type of shallow closure at the subcutaneous level may influence outcomes and complications after hip and/or knee replacement. 64% of surgeons use single-use incisional negative pressure therapy for the treatment of surgical wound complications (seroma, prolonged drainage, dehiscence). ConclusionsThere is a high level of variability in wound closure in our setting and a low level of training on the subject. The authors recommend that the different scientific societies invest resources to improve training in this field and reduce the percentage of surgeons who are considered inadequately trained, as well as adapting closure techniques to those considered gold standard according to the evidence.

OGC O09 Fluorescence lymphography using indocyanine green in the prevention of chyle leakage after minimally invasive esophagectomy

Abstract Background For oncological reasons, the thoracic duct is resected during esophagectomy for cancer. Its anatomy and vulnerability render it prone to injury and mainly side branches and collaterals are often hard to visualize. Chyle leakage is one of the most challenging complications in esophagectomy, with an incidence of 14-21%. The clinical implications for patients are prolonged thoracic drainage and hospital admission, additional reinterventions, unpleasant dietary restrictions, and decreased long-term survival. Fluorescence lymphography using indocyanine green (ICG) can accurately visualize the thoracic duct and collaterals, which may possibly reduce the incidence of chyle leakage and intra-operative detected chyle leakage can be treated directly. Methods A prospective observational cohort study will be performed. Patients aged over 18 years with resectable (cT1-4a, N0-3, M0) esophageal carcinoma undergoing a minimally invasive esophagectomy will be included. The primary endpoint of the study is postoperative chyle leakage. Secondary endpoints are overall morbidity and mortality, nature of dietary restrictions, reinterventions, hospital costs, 2 year survival rate and quality of life. Twenty-five milligram of ICG is dissolved in 10 ml of sterile water, obtaining a solution of 2.5 mg ICG per mL. In the McKeown esophagectomy, before the thoracic phase, the surgeon administers a bilateral bolus of 2 mL ultrasound-guided into inguinal lymph nodes. In an Ivor Lewis esophagectomy, 2mL of reconstituted ICG will be injected into the small bowel mesenteric root just under the peritoneum of the mesentery, at the level where the jejunostomy is placed. Additionally, 50 mL of cream is enterally administered through the just established feeding jejunostomy. Subsequently, the operating area is inspected for chyle leakage with fluorescence lymphography after thoracic duct ligation and just before terminating the procedure. Results We aim to include 50 patients to assess the feasibility of fluorescent lymphography using ICG and enteral cream to prevent chyle leakage after minimally esophagectomy. Inclusion is ongoing. At this time 39 of 50 patients are included. Results will be expected before the congress. Conclusions It is hypothesized that as a result of this technique the patients will benefit from lower incidence of postoperative chyle leakage, shorter thoracic drainage, reduced hospital admission, reduced dietary restriction, less re-interventions, and improved overall survival.

A 10-Year Retrospective Review on the Use of Prophylactic Spinal Reconstruction in Spinal Surgery Involving High-Risk Patients.

Spinal surgeries are being offered to a broader patient population who are both medically and surgically complex. History of prior spinal surgery, advanced age, and presence of comorbidities, such as obesity, malnutrition, steroid use, and tobacco use, are risk factors for postoperative complications. Prophylactic spinal reconstruction at the time of spinal surgery has been shown to have improved outcomes and decreased wound complications; however, outcomes focusing specifically on complex patients with a history of previous spinal surgery (or surgeries) have not been well described. This is a retrospective study performed at the University of Maryland Medical Center (Baltimore, MD) of high-risk patients who underwent complex spinal surgery with prophylactic spinal reconstruction from 2011 to 2022. One hundred forty-three consecutive surgeries from 136 patients were included in the study. Patients younger than 17 years or who had an incomplete medical record were excluded. Most patients were female (63.6%) versus male (31.5%). The average American Society of Anesthesiologists score was 3. All but 6 patients (11%) had a history of at least 1 spinal surgery, with nearly half of patients having had between 2 and 5 spinal surgeries. Reconstruction was performed with paraspinous flaps in most cases (n = 133 [93%]). The overall complication rate was 10.5%, with surgical site infection being the most common complication. Seventeen patients (12.5%) underwent reoperation within 90 days of initial surgery. Average length of follow-up was 4.18 months (range, 0.03-40.53 months). In appropriately selected patients, prophylactic spinal reconstruction offers improved outcomes with decreased wound complications compared with salvage. For large defects, paraspinous flaps are recommended over other reconstructive options. Prolonged drain placement is felt to be protective against complications.

The impact of liver abscess formation on prognosis of patients with malignant liver tumors after transarterial chemoembolization.

Liver abscess is a rare and serious complication after transarterial chemoembolization (TACE) for liver cancer; however, its impact on the prognosis is unclear. This retrospective study examined the outcomes of patients with liver abscess formation following TACE for malignant liver tumors to elucidate the impact of liver abscess formation on the prognosis of thesepatients. From January 2017 to January 2022, 1,387 patients with malignant tumors underwent 3,341 sessions of TACE at our hospital. Clinical characteristics of patients at baseline and follow-up were examined, including treatment and outcome of liver abscess, tumor response to the TACE leading to liver abscess, and overall survival time. Of 1,387 patients, 15 (1.1%) patients with liver abscess complications after TACE resulted in a total of 16 (0.5%) cases of liver abscess after 3,341 TACE sessions (including one patient with two events). After antibiotic or percutaneous catheter drainage (PCD) treatment, all the infections associated with liver abscesses were controlled. In the PCD group, eight patients died before drainage tube removal, one retained the drainage tube until the end of follow-up, and five underwent drainage tube removal; the mean drainage tube removal time was 149.17 ± 134.19 days. The efficacy of TACE leading to liver abscess was evaluated as partial response (18.75%), stable disease (37.5%), and progressive disease (43.75%). Eleven patients died during the follow-up period owing to causes unrelated to infections caused by liver abscesses. The survival rates at 3 months, 6 months, 1 year, and 5 years were 86.7%, 50.9%, 25.5%, and 17%,respectively. Patients with liver abscess formation following TACE for malignant liver tumors experienced prolonged drainage tube removal time after PCD; while this condition did not directly cause death, it indirectly contributed to a poor prognosis in these patients.

Predictive value of spinal CSF volume in the preoperative assessment of patients with idiopathic normal-pressure hydrocephalus.

The pathophysiology, diagnosis, and management of idiopathic normal pressure hydrocephalus (iNPH) remain unclear. Although some prognostic tests recommended in iNPH guidelines should have high sensitivity and high predictive value, there is often no positive clinical response to surgical treatment. In our study, 19 patients with clinical and neuroradiological signs of iNPH were selected for preoperative evaluation and possible further surgical treatment according to the guidelines. MR volumetry of the intracranial and spinal space was performed. Patients were exposed to prolonged external lumbar drainage in excess of 10 ml per hour during 3 days. Clinical response to lumbar drainage was assessed by a walk test and a mini-mental test. Twelve of 19 patients showed a positive clinical response and underwent a shunting procedure. Volumetric values of intracranial space content in responders and non-responders showed no statistically significant difference. Total CSF volume (sum of cranial and spinal CSF volumes) was higher than previously published. No correlation was found between spinal canal length, CSF pressure, and CSF spinal volume. The results show that there is a significantly higher CSF volume in the spinal space in the responder group (n = 12) (120.5 ± 14.9 ml) compared with the non-responder group (103.1 ± 27.4 ml; n = 7). This study demonstrates for the first time that CSF volume in the spinal space may have predictive value in the preoperative assessment of iNPH patients. The results suggest that patients with increased spinal CSF volume have decreased compliance. Additional prospective randomized clinical trials are needed to confirm our results.

Antegrade biliary stenting following surgical management of choledocholithiasis

Background: T-tube drainage of the common bile duct following bile duct exploration has been standard surgical practice for most of the past century. An important drawback of surgical duct exploration and clearance over ERCP is the need for prolonged external biliary drainage via T-tubes and consequently added morbidity. As such interest grew in reassessing the need for T-tube drainage after CBD Exploration. This was especially augmented by increased popularity of laparoscopic CBD exploration at the time of cholecystectomy which could provide a solution to both problems in a single sitting. Methods: This is a prospective observational study. We present a series of 31 cases of open and laparoscopic bile duct exploration where we closed the choledochotomy over an endo-biliary stent which was subsequently removed endoscopically, thus obviating external biliary drainage. Results: In this study 31 patients undergoing CBD exploration at our institution between January 2017 and August 2018 were included after informed consent. These patients underwent primary closure of the CBD over an endobiliary stent without any T-tube. The mean age of the patients was 42 years (36-57 yrs). 19 of the patients were female and 12 were male. The average operating time was 135 min (120-150 min) for open surgery and 160 min (140-170 min) for laparoscopic cases. The average number of days of hospitalization was 5 in laparoscopic cases (4-14 days) and 7 in open surgical cases (6-12 days). The median follow up of patients was up to 18moths years (8 mths-2 yrs). There were no cases of bilioma/intra-abdominal collections requiring drainage. On long term follow up we could not find any clinical/laboratory evidence of development of biliary strictures. Conclusions: Endobiliary stenting after open or laparoscopic bile duct exploration is a safe and attractive option for biliary drainage with many advantages over T-tube and can be achieved with minimal additional skill and operative time.

Review of patients discharged post thoracic surgery with chest drain in situ and nurse-based follow-up clinic.

Persistent air leaks and prolonged drainage are recognized complications of thoracic surgery, increasing hospital stay and costs. Patients can be discharged with a chest drain and followed up in a nurse-led clinic. We reviewed such patients and the rate of readmission after discharge to assess the effectiveness of the drain follow-up clinic. We conducted a retrospective review of our prospective database spanning 22 months, from March 2019 to January 2021. The analysis focused on the indication and duration of chest drainage, complications, and readmission for any reason. 62 patients (representing 5% of all thoracic surgery patients) were discharged with a chest drain. The median age was 67 years (range 22-85 years), with 24 females and 38 males. 52% underwent video-assisted thoracoscopic surgery, 27% had a thoracotomy, and 21% had bedside chest drain insertion. Following discharge, the median duration of chest drainage was 11 days [interquartile range (IQR) 7-18.75 days]. Patients had 106 review episodes in the ward-based nurse-led clinic. The indications were prolonged air leak (71%; 72 clinic reviews), persistent fluid drainage following empyema evacuation (16%; 24 clinic reviews), and persistent fluid drainage for simple effusion (13%; 10 clinic reviews). The median length of drain stay was 30 days (IQR 19.75-54 days) for empyema, 10 days (IQR 6-16 days) for air leak, and 8 days (IQR 6.5-12 days) for simple effusion. 9 patients required readmission (14.5%), and empyema had developed in 3 patients (4.8%). Patients discharged with a chest drain in place can be followed up in a dedicated ward-based nurse-led monitoring clinic for optimal quality of care.

322. FLUORESCENCE LYMPHOGRAPHY USING INDOCYANINE GREEN IN THE PREVENTION OF CHYLE LEAKAGE AFTER MINIMALLY INVASIVE ESOPHAGECTOMY

Partial versus radical nephrectomy in pT2a renal cell carcinoma tumors: which is the superior surgical approach?

BackgroundControversy persists regarding the superiority of partial nephrectomy (PN) versus radical nephrectomy (RN) in pT2a renal cell carcinoma (RCC) tumors. In this study we aimed to compare survival and clinical outcomes between these two techniques in Iran.MethodsIn this retrospective cohort, 96 patients who underwent either RN or PN for their pT2a RCC tumors were included. Overall survival (OS), cancer specific survival (CSS), recurrence free survival (RFS), major postoperative complications and postoperative renal function were compared, subsequently.ResultsDuring a mean follow-up time of 57.3 ± 24.0 months, OS, CSS, RFS, postoperative bleeding, postoperative urinary leak, postoperative prolonged wound drainage and length of hospital stay were not statistically different between RN versus PN patients (p = .09, .42, .09, .27, .27, .06 and .78, respectively). Nevertheless, post-operative creatinine was significantly lower in PN patients compared to RN patients (p = .01). Our multivariable cox regression models indicated that higher Fuhrman grade detrimentally affected CSS (p < .01) and increased the risk of recurrence (p = .02). Moreover, prior history of ischemic heart disease (IHD) was a significant determinant of lower OS (p = .03) and RFS (p = .02).ConclusionsIn conclusion, our data suggested that although OS, CSS, RFS and major postoperative complications were similar between PN and RN, PN may offer better postoperative renal function and can be thus regarded as the superior approach in pT2a tumors.

Management of the Leaky Wound After Arthroplasty: A Review

Total knee and hip arthroplasty are widely performed surgeries for end stage osteoarthritis with highly successful outcomes. However, prolonged postsurgical wound drainage leads to slower healing and predisposes to periprosthetic joint infection. Persistent wound discharge after joint arthroplasty affects patient satisfaction and outcome measures, can cause unexplained re-admissions, and increases the cost burden on the health system. Preventive measures are crucial and include preoperative nutritional assessment, achieving adequate hemostasis, minimizing dead spaces and watertight wound closure. Monitoring these patients with serial C-reactive protein levels is strongly recommended. Many management strategies have been described for such complications, including cessation of deep venous thrombosis prophylaxis, dressings and wound care, antimicrobial therapy, surgical washout and polyethylene insert replacement. However, these conditions are not addressed thoroughly in the literature and optimal management protocol for such complications is still lacking. This article aimed to review the best available literature to date and summarize the findings to help physicians treating these wounds develop objective guidelines in identifying and managing such conditions.

Factors contributing to prolonged drain duration in prepectoral staged implant-based breast reconstruction

Factors contributing to prolonged drain duration in prepectoral staged implant-based breast reconstruction
