Combined Resection Approaches: Decision Making for Synchronous Resection, Timing of Staged Intervention to Optimize Outcome.

Advancement in systemic and regional radiation therapy, surgical technique, and anesthesia has provided a path for increased long-term survival and potential cure for more patients with stage IV rectal cancer in recent years. When patients have resectable disease, the sequence for surgical resection is classified in three strategies: classic, simultaneous, or combined, and reversed. The classic approach consists of rectal cancer resection followed by metastatic disease at a subsequent operation. Simultaneous resection addresses both rectal and metastatic disease in a single surgery. The reversed approach treats metastatic disease first, followed by the primary tumor in several months. Simultaneous resection is appropriate for selected patients to avoid delay of definitive surgery, and reduce number of surgeries, hospital stay, and cost to the health care system. It may also improve patients' psychological effect. Multidisciplinary discussions including colorectal and liver surgeons to review patients' baseline medical conditions, tumor biology and behavior, and disease burden and distribution is imperative to guide proper patient selection for simultaneous resection and perioperative treatments.

Pulmonary Hypertension and Transbronchial Lung Biopsy: Does It Increase the Risk of Hemorrhage?

Background Bronchoscopy with transbronchial lung biopsy (TBLB) is commonly used as a diagnostic tool for pulmonary disease. Hemorrhage is a major complication of TBLB. While pulmonary hypertension (PH) is considered a risk factor, evidence supporting this is limited. In this study, we compare complications of TBLB in patients with PH to those without PH. Material and methods We performed a retrospective review of patients who underwent TBLB in our institution from January 2010 to May 2016. PH and non-PH groups were compared with respect to patient demographics, biopsy guidance, number of lobes biopsied (single or multiple), positive pressure ventilation, pre- and post-procedure diagnoses, and complications. Complications were defined as major hemorrhage, prolonged intubation, and reintubation within 72 hours from TBLB. Results The PH group had 45 patients with a mean age of 71 ± 14 years, and the non-PH group had 349 patients with a mean age of 63 ± 14 years. There were no significant differences with regards to gender, pre-procedure anticoagulation and antiplatelet agents, biopsy guidance, or number of lobes biopsied (p > 0.371). There was no significant difference in the occurrence of major hemorrhage between the two groups (p = 0.491). Prolonged intubation occurred more frequently in the PH group (p = 0.007). Conclusions There appears to be no increased risk of post-procedure hemorrhage with TBLB in patients with mild PH. There is, however, an increased risk of post-procedure prolonged intubation in these patients.

Extraperineal enterocele in male: A case report and literature review.

INTRODUCTION: Enterocele is a herniation of the small bowel through the cul-de-sac. It is uncommon and most often seen in elder females. Large enterocele manifesting as rectal prolapse is exceedingly rare and only few cases are reported previously. Due to it rarity, the best surgical treatment is not yet established especially in male patients. We present a case of enterocele causing rectal prolapse in a male patient that was treated surgically. PRESENTATION OF CASE: A 47-year-old African American male with chronic constipation and straining presented with manually reducible rectal prolapse. A defecography revealed a large enterocele prolapsing through the anterior rectal wall. The patient underwent an open posterior suture rectopexy with peritoneoplasty. His symptoms completely resolved after surgery, and repeat defecography three months after the procedure showed no sign of recurrence. DISCUSSION & CONCLUSION: Extraperineal enterocele in male is a rare disease. Rectopexy with peritoneoplasty can provide a great symptom relieve and improvement on defecography. Long-term outcome should be evaluated.

Incidence of Surgical Site Infections after Thyroid and Parathyroid Surgery: No Role for Antimicrobial Prophylaxis.

To better define the value of antimicrobial prophylaxis (AMP) and antiseptic skin preparation (ASP) in thyroid and parathyroid surgery, we examined the rate of surgical site infections (SSIs) with and without AMP. Retrospective analysis was performed using the National Surgical Quality Improvement Program database at a single institution. Patients undergoing thyroid or parathyroid surgery with data entered into the National Surgical Quality Improvement Program database at our institution between November 2007 and June 2015 were studied, including patient demographics, wound classification, other risk factors for SSI, and wound outcome. Charts were retrospectively reviewed for AMP, ASP, and use of drains. Of the 534 patients who underwent thyroid (n = 358) or parathyroid (n = 176) surgery, 58 (10.9%) were diabetic, 54 (10.1%) used tobacco, and 14 (2.6%) were on steroids. Most wounds were classified as "clean" (99.6%). Betadine was used for ASP in 96 per cent. AMP was given to 141 patients (26%) using cefazolin, vancomycin, or clindamycin. The remaining 393 patients (74%) received no AMP. Zero infections occurred in the group who did not receive AMP. One (0.7%) superficial, nonpurulent SSI occurred in the group that received AMP which was not statistically significantly different (P = 0.319). The rates of SSI after thyroid and parathyroid surgery are extremely low, around two per 1000 cases, and do not decrease with AMP. Therefore, AMP is not necessary in thyroid and parathyroid surgery and should be avoided to reduce costs, adverse reactions, and antibiotic resistance.

Endovascular Repair of Three Concurrent Mycotic Pseudoaneurysms.

INTRODUCTION: Mycotic pseudoaneurysm has traditionally been repaired surgically with excision of the infected artery and revascularization via extra-anatomical or in situ bypass. There have been reports of endovascular repair for high-risk patients for formal surgical repair. We present a case of a patient with 3 large pseudoaneurysms arising from the right subclavian artery, descending thoracic aorta, and right popliteal artery treated with endovascular and hybrid intervention. CASE: A 74-year-old male with remote history of coronary artery bypass graft and recent sternoclavicular joint abscess developed 3 concurrent pseudoaneurysms arising from the right subclavian artery, distal descending thoracic aorta, and right popliteal artery. He underwent right axillary to common carotid bypass with endovascular stent graft placement in the distal innominate and proximal subclavian artery, and subsequently had thoracic endovascular aortic repair and right popliteal stent graft. Four months later, he presented with hemoptysis due to compression of the lung secondary to the pseudoaneurysm. He underwent right anterior thoracotomy and debridement of the pseudoaneurysm. Patient recovered from the procedure and discharged. CONCLUSION: Endovascular repair of mycotic pseudoaneurysm is an acceptable alternative for high-risk patients. Even when open approach became necessarily, endovascular stent graft decreased blood loss and morbidity.

Sarcoid-Like Mediastinal Lymphadenopathy in Gynecologic Malignancy.

Noncaseating granulomas are seen surrounding tumors with varying frequency, possibly as part of an immune response to tumor cells. However, data about the association of sarcoid with gynecologic malignancy is sparse. We performed a search of our institutional database for all EBUS-TBNA biopsies conducted within the past five years that revealed granulomatous inflammation. All adult female patients with a history of gynecologic malignancy were included. Patients with a history of sarcoidosis or fungal or mycobacterial infection were excluded. All patients with evidence of malignant cells on TBNA specimen were excluded. Our results revealed 65 patients with histologic diagnosis of a noncaseating granuloma on EBUS-TBNA. Five patients (7.69%) had a history of gynecologic malignancy. Two patients had evidence of PET-positive nodes on surveillance scans, which led directly to the examination. Our findings suggest that distant malignancies may cause granulomatous lymphadenitis, through yet undefined mechanisms. As such, patients with evidence of mediastinal lymphadenopathy could benefit from routine sampling and histologic examination to define the pathology in the correct clinical context.

Lung Resection in the Postpneumonectomy Patient.

Pulmonary resection after pneumonectomy is a reasonable option in selected patients. Wedge resection for single peripheral metachronous disease has the best outcome with 5-year survival as high as 63%. Current and predicted postoperative cardiopulmonary reserve should be evaluated carefully. Stereotactic body radiotherapy is a promising alternative for inoperable patients.

Elective intubation and positive pressure ventilation for transbronchial lung biopsy.

BACKGROUND: The safety of transbronchial lung biopsy (TBLB) on positive pressure mechanical ventilation has been controversial due to a presumed risk of pneumothorax. Data are especially limited on TBLB with elective intubation and mechanical ventilation. In this study, we compared complications of TBLB in patients who were electively mechanically ventilated for the procedure to those who were not. MATERIAL AND METHODS: A retrospective review of nonventilator-dependent patients who underwent TBLB in our institution from January 2010 to May 2016 was performed. The mechanical ventilation (MV) and nonmechanical ventilation (NMV) groups were compared with respect to patient demographics, numbers of lobes biopsied (single or multiple), preprocedure and postprocedure diagnoses, and complications. Complications were defined as pneumothorax of any size, major hemorrhage, prolonged intubation, and reintubation within 72 hours from TBLB. RESULTS: A total of 394 patients were identified. The MV group had 351 patients with mean age of 64.6 years, and the NMV group had 43 patients with mean age of 60.0 years. There were no significant differences with regards to age, gender, or number of lobes biopsied. There was no significant difference in the occurrence of pneumothorax (5.4% versus 4.7%, P = 1.00), hemorrhage (1.7% versus 4.7%, P = 0.21), and prolonged intubation or reintubation (3.1% versus 2.3%, P = 1.00) between the two groups. CONCLUSIONS: When performing TBLB, there was no significant difference observed in the rate of complications between MV and NMV groups. Elective positive pressure mechanical ventilation for TBLB for nonventilator-dependent patients is safe and does not increase the risk of complications.

Efficiency of preoperative esophagogastroduodenoscopy in identifying operable hiatal hernia for bariatric surgery patients.

BACKGROUND: Gastroesophageal reflux (GERD) is a symptom frequently found in obese patients, and often is related to the presence of a hiatal hernia (HH). Surgeons may evaluate for the presence of HH on esophagogastroduodenoscopy (EGD). However, preoperative endoscopic presence or absence of a significant HH does not always correlate with intraoperative findings. OBJECTIVE: To compare the rate of detection of repairable HH between clinical, endoscopic, and intraoperative methods SETTING: Independent, university-affiliated teaching hospital METHODS: A retrospective chart review of all consecutive patients who had undergone a primary bariatric procedure sleeve gastrectomy, gastric bypass, or biliopancreatic diversion/duodenal switch with routine preoperative EGD in a single institution from 2009-2013 was performed. Data points included the diagnosis of GERD/heartburn/proton pump inhibitor or histamine antagonist from history, the diagnosis of HH from preoperative EGD, and the diagnosis of HH intraoperatively that merited repair. RESULTS: 1570 consecutive patients were included in the study. Eight hundred fifty-seven (55%) had diagnosis of GERD or heartburn, and 713 (45%) were asymptomatic (negative for GERD or heartburn). Hiatal hernia repair was performed in 153 (18%) patients with the diagnosis of GERD or heartburn and in 107 (15%) patients without the diagnosis of GERD and or heartburn. In all, 434 (28%) out of 1570 patients had a finding of HH on EGD; 204 (47%) were repaired. On endoscopy, 326 (75%) were defined as small, 87 (20%) as moderate, and 21(5%) as large HH. Of these, repairs were done on 128 (39%), 60 (70%), and 16 (76%). The sensitivity of detecting repairable HH by clinical indicators such as GERD or heartburn was 55% (P = .123) and sensitivity of EGD findings was 78% (P = .000). Specificity was 46% and 82%, respectively. CONCLUSION: Small HH are over-diagnosed with EGD, as most do not require repair. However, moderate and large HH are accurately detected.

Rationale for a Minimum Number of Lymph Nodes Removed with Non-Small Cell Lung Cancer Resection: Correlating the Number of Nodes Removed with Survival in 98,970 Patients.

BACKGROUND: The benefit of thoracic lymphadenectomy in the treatment of resectable non-small cell lung cancer (NSCLC) continues to be debated. We hypothesized that the number of lymph nodes (LNs) removed for patients with pathologic node-negative NSCLC would correlate with survival. METHODS: The National Cancer Data Base (NCDB) was queried for resected, node-negative, NSCLC patients treated between 2004 and 2014. Patients were grouped according to the number of LNs removed (1-4, 5-8, 9-12, 13-16, and ≥17). Patients with <10 LNs removed were also compared with those with ≥10 LNs removed. A Cox regression analysis was performed and hazard ratios (HRs) calculated, with 95 % confidence intervals (CIs). RESULTS: Of 1,089,880 patients with NSCLC reported to the NCDB during the study period, 98,970 (9.0 %) underwent resection without evidence of pathologic nodal involvement. Lobectomy was performed in 83.9 %, sublobar resection was performed in 12.7 % and pneumonectomy was performed in 2.8 % of patients. The number of LNs removed correlated with increasing tumor size and extent of resection. On multivariate analysis, increasing age, male sex, white ethnicity, high tumor grade, larger tumor size, pneumonectomy, and positive surgical margins were all negatively correlated with overall survival. The number of LNs removed and lobectomy/bi-lobectomy correlated with improved survival. The removal of <10 LNs was associated with a 12 % increased risk of death (HR: 1.12, 95 % CI 1.09-1.14; p < 0.001). CONCLUSION: Survival of early-stage NSCLC patients is associated with the number of LNs removed. The surgical management of early-stage NSCLC should include thoracic lymphadenectomy of at least 10 nodes.
