Impact of Chemoradiation-to-Surgery Interval on Pathological Complete Response and Short- and Long-Term Overall Survival in Esophageal Cancer Patients.

BACKGROUND: The impact of the neoadjuvant chemoradiation-to-surgery (CRT-S) interval in patients with esophageal cancer is not clear. We aimed to determine the relationship between CRT-S interval and pathological complete response rate (pCR) and overall survival (OS). METHODS: National Cancer Data Base patients with CRT followed by surgery were studied. CRT-S interval was studied as a continuous (weeks) and categorical variable (quintiles: 15-37, 38-45, 46-53, 54-64, and 65-90 days, with n = 1016, 1063, 1081, 1083, and 938 patients, respectively). RESULTS: A total of 5181 patients were included; 81% had adenocarcinoma. There was a significant increase of pCR rate across quintiles (18%, 21%, 24%, 25%, and 29%, p < 0.001) and per week increase of CRT-S interval [odds ratio (OR) 1.11, p < 0.001]. The 90-day mortality increased as CRT-S increased across quintiles (5.7%, 6.2%, 6.8%, 8.5%, and 8.2%, p = 0.02) and through weeks (OR 1.05, p = 0.03). Mean OS across CRT-S quintiles was 36.4, 35.1, 33.9, 33.2, and 30.7 months, respectively. Multivariate Cox regression showed significantly worse OS per week increase in CRT-S interval [hazard ratio (HR) 1.02, p = 0.02], especially among the last quintile (CRT-S = 65-90 days: HR 1.2, p = 0.009). The squamous cell carcinoma (SCC) and pCR groups had similar OS across CTR-S intervals. CONCLUSIONS: Despite the higher pCR rate with longer CRT-S interval, surgery is optimal less than 65 days after CRT to avoid worse 90-day mortality and achieve better OS. In patients with SCC and those with pCR, prolonged CRT-S interval had no impact on OS. Further studies are needed to consolidate our findings.

The Role of Completion Lymphadenectomy in Positive Regional Lymph Nodes in Melanoma: A Meta-analysis.

BACKGROUND: The optimal management of melanoma with positive sentinel lymph node (SLN) remains unclear. Completion lymph node dissection (CLND) only yields additional positive non-SLN in 20% of cases and its benefits on survival remains debatable. METHODS: An online database search of Medline was performed; key bibliographies were reviewed. Studies comparing outcomes after CLND versus observation were included. Odds ratios (ORs) with the corresponding 95% confidence intervals (CIs) by random fixed effects models of pooled data were calculated. The primary endpoints were disease-free survival (DFS), melanoma-specific survival (MSS), and overall survival (OS). RESULTS: Search strategy yielded 117 publications. Twelve studies were selected for inclusion, comprising 7966 SLN-positive patients. Among these patients, 5306 (66.6%) subjects underwent CLND and 2660 (33.4%) patients were observed. Median Breslow thickness and ulceration were similar between groups (2.8 ± 0.6 mm versus 2.5 ± 0.8 mm, P = 0.721; and 38.8% versus 37.2%, P = 0.136, CLND versus observation, respectively). CLND was associated with statistically significant improved 3-y (71.0% versus 66.2%, OR 0.82, 95% CI 0.69-0.97, P = 0.02) and 5-y DFS (48.3% versus 47.8%, OR 0.75, 95% CI 0.59-0.96, P = 0.02) compared with observation. However, no difference was demonstrated in 3-y MSS (83.7% versus 84.7%, OR 1.09, 95% CI 0.88-1.35, P = 0.41), 5-y MSS (68.4% versus 69.8%, OR 1.02, 95% CI 0.88-1.19, P = 0.78), or OS (68.2% versus 78.9%, OR 0.93, 95% CI 0.55-1.57, P = 0.78). CONCLUSIONS: Based on this large-scale analysis, CLND improved both 3- and 5-y DFS, possibly because of increased rates of local control; however, this did not translate in improved MSS or OS. Efforts toward the identification of molecular markers associated with poor outcomes in SLN-positive patients who undergo observation are warranted.

Perioperative and oncological outcomes of abdominoperineal resection in the prone position vs the classic lithotomy position: A systematic review with meta-analysis.

BACKGROUND AND OBJECTIVES: This study is a systematic review with meta-analysis designed to compare the perioperative and oncological outcomes of the abdominoperineal resection (APR) carried out in the prone jack-knife position (P-APR) vs the classic lithotomy position (C-APR). METHODS: We conducted an electronic search through PubMed utilizing the PRISMA guidelines. We included all randomized and nonrandomized studies which allowed for comparative analysis between the two groups. Research that focused on and analyzed the extralevator abdominal excision were excluded. Pooled variables and number of events were analyzed using the random-effect model. RESULTS: The final analysis included seven nonrandomized retrospective cohorts encompassing 1663 patients. P-APR was associated with decreased operative time (OT) (DM, -43.8 minutes; P < 0.01) and estimated blood loss (EBL) (DM, 86.9 mL; P < 0.01). There were no observed differences regarding perineal wound infections (PWI) (odds ratio [OR], 0.36; P = 0.18), intraoperative perforation of rectum (IOP) (OR, 0.98; P = 0.97), circumferential resection margin (CRM) positivity (OR, 1.02; P = 0.98) or 5-year LR (OR, 1.00; P = 0.99). CONCLUSION: The prone approach for APR is associated with decreased EBL and OT, although not with any change in the incidence of PWI or IOP. Moreover, surgical positioning per se does not appear to affect the CRM positivity rates or LR rate.

Long-term Quality of Life and Gastrointestinal Functional Outcomes After Pancreaticoduodenectomy.

OBJECTIVE: To perform a comprehensive assessment of long-term quality of life (QOL) and gastrointestinal (GI) function in patients following pancreaticoduodenectomy (PD). SUMMARY OF BACKGROUND DATA: Survival after PD has greatly improved and thus has resulted in a larger population of survivors, yet long-term QOL and GI function after PD is largely unknown. METHODS: Patients were identified from a global online support group. QOL was measured using the Short Form-36, while GI function was assessed using the Gastrointestinal Symptom Rating Scale. QOL and GI function were analyzed across subgroups based on time after PD. QOL was compared with preoperative measurements and with established values of a general healthy population (GHP). Multivariate linear regression was used to identify predictors of QOL. RESULTS: Of the 7605 members of the online support group, 1102 responded to the questionnaire with 927 responders meeting inclusion criteria. Seven hundred seventeen (77.3%) of these responders underwent PD for malignancy. Mean age was 57 ±â€Š12 years and 327 (35%) were male. At the time of survey, patients were 2.0 (0.7, 4.3) years out from surgery, with a maximum 30.7-year response following PD. Emotional and physical domains of QOL improved with time and surpassed preoperative levels between 6 months and 1 year after PD (both P < 0.001). Each GI symptom worsened over time (all P < 0.001). Independent predictors of general QOL in long-term survivors (> 5 years) included total GSRS score [ß = -1.70 (-1.91, -1.50)], female sex [ß = 3.58 (0.67, 6.46)], and being a cancer survivor [ß = 3.93 (0.60, 7.25)]. CONCLUSIONS: Long-term QOL following PD improves over time, however never approaches that of a GHP. GI dysfunction persists in long-term survivors and is an independent predictor of poor QOL. Long-term physical, psychosocial, and GI functional support after PD is encouraged.

Autogenous hepatic tissue transplantation into the omentum in a novel ectopic liver regeneration murine model.

BACKGROUND: Liver regeneration involves hyperplasia and hypertrophy of hepatic cells. The capacity of macroscopic liver tissue to regenerate in ectopic sites is unknown. We aim to develop a novel in vivo model of ectopic liver survivability and regeneration and assess its functionality. METHODS: Adult male Sprague-Dawley rats (n = 23) were divided into four groups: (1) single-stage (SS) group, wedge liver resection was performed, and the parenchyma was directly implanted into the omentum; (2) double-stage (DS) group, omentum pedicle was transposed over the left hepatic lobe followed by wedge liver resection along with omental flap; (3) Biogel + DS group, rats received intraperitoneal injection of inert polymer particles prior to DS; (4) Biogel + DS + portal vein ligation (PVL) group, Biogel + DS rats underwent subsequent PVL. Hepatobiliary iminodiacetic acid scintigraphy assessed bile excretion from ectopic hepatic implants. RESULTS: Histologically, the scores of necrosis (P < 0.001) and fibrosis (P = 0.004) were significantly improved in rats undergoing DS procedure (groups 2, 3, and 4) compared with the SS group. Biogel rats (Biogel + DS and Biogel + DS + PVL) demonstrated statistically increased scores of bile duct neoformation (P = 0.002) compared to those without the particles (SS and DS). Scintigraphy demonstrated similar uptake of radiotracer by ectopic hepatic implants in groups 2, 3, and 4. CONCLUSIONS: Omental transposition provided adequate microcirculation for proliferation of ectopic hepatic cells after liver resection. Inert polymers enhanced the regeneration by promoting differentiation of new bile ducts. The ectopic hepatic implants showed preserved function on scintigraphy. This model provides insights into the capacity of liver parenchyma to regenerate in ectopic sites and the potential as therapeutic target for cell therapy in end-stage liver disease.

The Role of Surgical Resection for Stage IV Gastric Cancer With Synchronous Hepatic Metastasis.

BACKGROUND: With improved responses to chemotherapy and targeted treatments, the role of surgery in metastatic gastric cancer (MGC) to the liver needs to be revisited. We sought to examine whether surgical resection is associated with improvement of long-term survival. METHODS: The National Cancer Database was queried for MGC to the liver (2010-2014). Survival analysis was performed to compare the effect of gastrectomy and perioperative chemotherapy (G-CT) to palliative chemotherapy (PCT) alone. RESULTS: We identified 3175 patients with MGC to the liver. Most patients (94%, n = 2979) were treated with PCT, whereas 6% (n = 196 patients) underwent G-CT. Overall survival improved in patients treated with G-CT compared to PCT alone (16 versus 9.7 mo, P < 0.001). In patients undergoing G-CT, neoadjuvant chemotherapy was associated with increased overall survival compared to adjuvant chemotherapy (18.9 versus 14.8 mo, P = 0.011). Hazards of death significantly decreased with gastrectomy (hazard ratio [HR]: 0.53, 95% confidence interval [CI]: 0.44-0.63, P < 0.001). Negative prognostic factors included advanced age (HR: 1.10, 95% CI: 1.06-1.14, P < 0.001), treatment at nonacademic institution (HR: 1.23, 95% CI: 1.13-1.33, P < 0.001), and poorly differentiated grade (HR: 1.54, 95% CI: 1.17-2.03, P < 0.001). CONCLUSIONS: G-CT is associated with improved survival in patients with gastric cancer and synchronous liver metastasis. Further experience with well-designed prospective trials may be warranted to confirm these findings.

Utilisation of radiology rotations in ACGME-accredited general surgery programmes.

BACKGROUND: General surgery (GS) residents are often required to provide immediate preliminary interpretations of radiological images, especially in critical situations. It is unclear whether residents in Accreditation Council for Graduate Medical Education-accredited GS programmes receive sufficient radiological training to deliver adequate patient care. OBJECTIVES: Determine the utilisation of radiology rotations (RR) during GS residency. METHODS: Between February and March 2015, a pilot voluntary 19-item survey was electronically distributed to GS programme directors (PDs) regarding the availability and value of a RR during GS training. RESULTS: A total of 234 PDs received the questionnaire and the response rate was 36.8% (n=86). Sixty-five (77.4%) PDs expected their trainees to interpret imaging studies in the acute setting; however, only 8.3% of programmes had a dedicated RR. RRs are more prevalent among community-based than university-based programmes (71.4% vs 27.9% p=0.003). The implementation of a RR may be limited due to insufficient number of GS residents in the department (p=0.002). 75.4% of PDs expect GS residents to confirm their findings with a radiologist. In those programmes with RR, most PDs (85.7%) believed that a dedicated rotation improved GS residents' understanding of radiological imaging. CONCLUSION: The majority of PDs are currently not confident that GS residents are capable of interpreting radiological imaging independently; however, the implementation of a mandatory RR in GS residency curriculum yet seems to be controversial. Given the expectation of PDs and the continued need to improve patient care, the integration of a dedicated RR in GS training should be encouraged.

Impact of medical or surgical admission on outcomes of patients with acute cholecystitis.

BACKGROUND: Although acute cholecystitis (AC) is a surgical disease, patients with the condition may be admitted to medical-related services (MS). This may lead to delayed cholecystectomy thereby affecting outcomes and quality of care. METHODS: Between July 2010 and March 2013, 329 patients under 70 years old presented to a community-based tertiary care hospital with AC and underwent same admission cholecystectomy. Outcomes were compared between patients admitted to MS and surgical services (SS). RESULTS: Two hundred fifteen patients (65.3%) were admitted to a MS. Patients under the MS had longer LOS (3.0 days vs. 2.0 days, p < 0.001), waiting time to surgical consultation (7.3 h vs. 5.0 h, p < 0.001) and to cholecystectomy (1.0, 0-2 days vs. 1.0, 0-1 day, p < 0.001), and increased hospital costs ($3685 vs. $4,688, p < 0.001) compared to the SS. Readmission and mortality rates were not significantly different between groups. CONCLUSION: Patients under 70 years old with AC undergoing cholecystectomy admitted to MS had increased LOS, delay to the operation, and hospital costs compared to those admitted to a SS. Admission of patients with AC to a SS needs to be emphasized to reduce costs and improve quality of care.

Optimal Surgical Management for Occult Breast Carcinoma: A Meta-analysis.

BACKGROUND: Occult breast cancer (OBC) represents a rare clinical entity and poses a therapeutic dilemma. Due to limited experience, no optimal treatment approaches have yet been established. METHODS: A meta-analysis was performed using MEDLINE and EMBASE databases to identify all studies investigating the surgical options for OBC: (1) axillary lymph node dissection (ALND) with radiotherapy (XRT); (2) ALND with mastectomy; and (3) ALND alone. Comparative studies including nonoperative management (observation or XRT alone) were excluded. The primary endpoints were locoregional recurrence, distant metastasis, and mortality rates. RESULTS: The literature search yielded 42 publications. Seven studies met the inclusion criteria comprising 241 patients. Among these patients, 94 (39 %) underwent ALND with XRT, 112 (46.5 %) underwent mastectomy, and 35 (14.5 %) underwent ALND alone. Mean follow-up was 61.8 ± 16.2 months (range 5-396 months). Locoregional recurrence (12.7 vs. 9.8 %), distant metastasis (7.2 vs. 12.7 %), and mortality rates (9.5 vs. 17.9 %) were similar between ALND with XRT and mastectomy. ALND with XRT was superior to ALND alone regarding locoregional recurrence (12.7 vs. 34.3 %, p < 0.01) and there was a trend toward improved mortality rates (9.5 vs. 31.4 %, p = 0.09). CONCLUSIONS: There was no difference in survival outcomes between mastectomy and ALND with XRT of patients with OBC. Radiotherapy improves locoregional recurrence and, possibly mortality rates of patients undergoing ALND. Based on this meta-analysis, combined ALND and radiation therapy may appear as the optimal surgical approach in these patients.

Vascular Reconstruction Is Not Warranted in Most Civilian Traumatic Shank Vascular Injuries.

BACKGROUND: Operative management of traumatic shank vascular injuries (SVI) evolved significantly in the past few decades, thereby leading to a dramatic decrease in amputation rates. However, there is still controversy regarding the minimum number of patent shank arteries sufficient for limb salvage. METHODS: Between January 2006 and September 2011, 191 adult trauma patients presented to an urban level I trauma center in Miami, Florida, with traumatic lower extremity vascular injuries. Variables collected included age, gender, mechanism of injury, and clinical status at presentation. Surgical data included vessel injury, technical aspects of repair, associated complications, and outcomes. RESULTS: A total of 48 (25.1%) patients were identified comprising 66 traumatic shank arterial injuries. Mean age was 38.2 ± 13.4 years, and the majority of patients were men (40 patients, 83.3%) presenting with blunt injuries (35 patients, 72.9%). Ligation was performed in 38 injured arteries (57.6%) and no vascular intervention was required in 20% of the patients. Vascular reconstruction was performed in only 6 patients (9.1%): 4 (6.1%) with concurrent popliteal trauma, 1 (1.5%) isolated anterior tibial, and 1 (1.5%) 3-vessel injury. Autogenous venous interposition conduit and polytetrafluoroethylene grafting were performed in 5 (7.6%) and 1 (1.5%) patient, respectively. All amputations (8 patients, 16.7%) occurred in blunt trauma patients presenting with unsalvageable limbs. The overall mortality rate in this series was 2.1%. CONCLUSIONS: Civilian shank arterial injuries are associated with acceptable rates of limb loss. Patients with a single-vessel patent inflow did not require vascular reconstruction in this series. Arterial reconstruction may no longer be determinant for successful management of isolated and double arterial SVI, whereas it is yet essential in the presence of 3-vessel or concurrent above-the-knee vascular injuries. Further investigation including larger number of patients is still warranted to define the role of conservative management in these complex injuries.

Repair of an acute blunt popliteal artery trauma via endovascular approach.

Popliteal vascular trauma remains a challenging entity and carries the greatest risk of limb loss among the lower extremity vascular injuries. Operative management of patients presenting with traumatic popliteal vascular injuries continues to evolve. We present a case of successful endovascular repair with stent grafting of an acute blunt popliteal artery injury. Endovascular repair of traumatic popliteal vascular injuries appears as an attractive alternative to surgical repair in a very selective group of patients. Further investigation is still needed to define the safety and feasibility of endovascular approach in the management of traumatic popliteal vascular injuries.

The role of MR cholangiopancreatography in preoperative assessment for repair of major iatrogenic biliary injury: 10-year experience.

BACKGROUND/AIMS: Major iatrogenic biliary injury is a potentially life-threatening complication after laparoscopic cholecystectomy. Early diagnosis is essential to improve outcomes, however, to date, there is no consensus regarding the best imaging approach for preoperative assessment of these injuries. METHODOLOGY: From March 2002 to February 2012, 40 patients with postoperative major biliary injury underwent biliary reconstruction at our Institution. Mean age was 51.7 ± 18.1 years (19-86) with 30 (75%) females. Magnetic resonance cholangiopancreatography (MRCP) were compared with different diagnostic modalities and definitive intraoperative findings. RESULTS: Of 40 patients, 10 (25%) had Bismuth type I, 10 (25%) Bismuth type II, 6 (15%) Bismuth type III injury, 10 (25%) Bismuth type IV and, 4 (10%) Bismuth type V. MRCP has similar accuracy to define injury site, but is superior in delineating proximal ductal anatomy that was often not visualized with endoscopic retrograde cholangiopancreatography (ERCP). CONCLUSION: MRCP is a reliable, accurate and readily available diagnostic tool to assess complex biliary injuries. It provides adequate visualization of the proximal and distal biliary trees and may be considered as first-line test in the management of major iatrogenic biliary injuries. Revision of current guidelines for diagnostic approach of this condition is warranted.

Pancreatic intraepithelial neoplasia arising from an ectopic pancreas in the small bowel.

BACKGROUND: Ectopic pancreatic tissue is relatively uncommon, and is characterized as pancreatic tissue with no contact with the normal pancreas, and with its own ductal system and blood supply. It is usually asymptomatic, and can be incidentally diagnosed by conventional imaging studies. METHOD: A 69-year-old woman with a prior history of bilateral breast carcinoma presented with ectopic pancreatic intraepithelial neoplasia (PanIN) that was identified incidentally in the small bowel during an oncological resection of a synchronous primary pancreatic adenocarcinoma, and renal cell carcinoma. RESULTS: The patient underwent subtotal pancreatectomy with splenectomy, regional lymphadenectomy, radical left nephrectomy, and small bowel resection with primary anastomosis of ectopic PanIN-2. She had an uneventful hospitalization and was discharged home on postoperative day 7. CONCLUSIONS: The occurrence of ectopic PanIN is extremely unusual with only few cases previously reported in the literature. The need for negative margins after surgical resection of ectopic PanIN lesions remains controversial.

Replacement of infected aortic prosthetic graft with aortic homograft after heart transplantation: 13-year follow-up.

Acute ascending aortic dissection (AAAD) is a rare complication after orthotopic heart transplantation. We report a patient with AAAD after heart transplantation in whom repair was complicated by infection of the ascending aortic prosthetic graft. This was successfully managed by re-do replacement with two cryopreserved aortic homografts. Despite extensive calcification in the wall, the homografts show no aneurysm or dilation after 10 years.

Robotic removal of eroded vaginal mesh into the bladder.

Vaginal mesh erosion into the bladder after midurethral sling procedure or cystocele repair is uncommon, with only a few cases having been reported in the literature. The ideal surgical management is still controversial. Current options for removal of eroded mesh include: endoscopic, transvaginal or abdominal (either open or laparoscopic) approaches. We, herein, present the first case of robotic removal of a large eroded vaginal mesh into the bladder and discuss potential benefits and limitations of the technique.

Biliary-colonic fistula caused by cholecystectomy bile duct injury.

Biliary-colonic fistula is a rare complication after laparoscopic cholecystectomy. We present a case of post-cholecystectomy iatrogenic biliary injury that resulted in a fistula between the common hepatic duct and large bowel. Magnetic resonance cholangiopancreatography provided good visualization of injury even with concurrent normal level of alkaline phosphatase. Radiologic findings and surgical management of this condition are discussed in detail.

Unexpected persistent left superior vena cava and absent right superior vena cava in situs solitus patient.

We, herein, report a patient with persistent left superior vena cava with enlarged coronary sinus and absent right superior vena cava. This anomaly, diagnosed intraoperatively during the third open-heart surgery in the course of transesophageal echocardiography examination, was not mentioned during the patient's previous two cardiac operations. Challenges in intraoperative management and implications for subsequent treatments are discussed.

Beating heart valve surgery in patients with low left ventricular ejection fraction.

BACKGROUND: Patients with very low left ventricular ejection fraction (LVEF) are at high risk for valve surgery. We herein present our experience with beating heart valve surgery in such patients. METHODS: From May 2000 to October 2006, 346 consecutive patients underwent beating heart valve surgery. Of these, 50 patients had LVEF <30%: 7 had LVEF 21 to 29%, 34 had LVEF <20%, and 9 had LVEF <10%. Mean age was 57.44 +/- 12.45 years (range 28 to 85 years). There were 40 males (80%) and 10 females (20%). RESULTS: Isolated mitral valve (MV) and aortic valve replacements were performed in 11 (22%) and 10 (20%) of patients, respectively. Fourteen (28%) patients underwent combined coronary artery bypass grafting and valve replacements. MV repairs were performed; 13 (26%) patients and 2 (4%) patients had combined MV replacements and tricuspid repairs. Mean hospital stay was 15.37 +/- 13.12 days (range 3 to 55 days). Overall early mortality (<30 days) was 6% (three patients) and one patient (2%) died late (>30 days). CONCLUSIONS: Beating heart valve surgery in patients with poor LVEF yields results similar to conventional surgery using cardioplegia. Additional studies are needed to fully evaluate the potential benefits of this method of myocardial perfusion for this high-risk group of patients.

Paradigm change in the management of patients with acute type A aortic dissection who had prior cardiac surgery.

BACKGROUND: Acute type A aortic dissection (ATAAD) is a life-threatening disease entity. Untreated, it usually results in death due to rupture of the proximal aorta into the pericardial cavity, leading to cardiac tamponade. Should patients who have had prior cardiac surgery presenting with ATAAD be treated emergently with surgery, or should they be managed medically? We herein present preliminary evidence that suggests that medical treatment, at least initially, is the best option for these patients. Surgery is indicated in the follow-up, depending on increased size of the dissection or aorta, or to prevent or treat complications. PATIENTS AND METHODS: From January 2004 to November 2009, ten consecutive male patients with prior cardiac surgery were admitted to hospital with the diagnosis of ATAAD. Mean age was 61.90 +/- 14.68 years (range, 36 to 79 years), with nine (90%) males and one (10%) female. All were treated medically as the definitive form of management. RESULTS: Mean follow-up duration was 14.62 +/- 11.12 months (range, 1 to 31 months). Overall mortality during follow-up was 20% (two patients). Eight patients (80%) are alive and well. CONCLUSIONS: This initial experience with a small, consecutive series of patients, suggests that medical treatment is an option in the initial management of patients with ATAAD who had prior cardiac surgery. It appears that emergency surgery is seldom needed. A larger series of patients and longer follow-up period are needed prior to recommending this treatment approach for such patients.

Pulmonary embolectomy: recommendation for early surgical intervention.

BACKGROUND: Acute pulmonary embolism (PE) is a life-threatening disease which often results in death if not diagnosed early and treated aggressively. Despite all efforts at improving outcomes, there is no consensus on the management of acute severe PE. METHODS: From May 2000 to June 2009, 16 consecutive patients underwent surgical pulmonary embolectomy at our institution. Mean age was 45 +/- 17 years (range, 14 to 76) with nine (56%) males and seven (43%) females. Preoperatively, all cases were classified as massive PE; seven (43%) patients were in hemodynamic collapse and emergently underwent operation while receiving cardiopulmonary resuscitation. RESULTS: There were nine (56%) urgent/emergent and seven (44%) salvage patients undergoing surgical pulmonary embolectomy. Of nine nonsalvage patients, seven (77%) patients presented with moderate to severe right ventricular (RV) dilation/dysfunction. Mean cardiopulmonary bypass time was 43 +/- 41 minutes (range, 9 to 161). Mean follow-up duration was 48 +/- 38 months (range: 0.3 to 109), with seven in-hospital deaths (43%): mortality was 11% (1/9) in emergent operations and 85% (6/7) in salvage operations. CONCLUSIONS: Surgical pulmonary embolectomy should be considered early in the management of hemodynamically stable patients with PE who show evidence of RV dilation and/or failure, as it is associated with satisfactory outcomes. Conversely, pulmonary embolectomy has dismal results under salvage conditions. Revision of current guidelines for the surgical management of this condition may be warranted.
