Nonanatomic Thoracoscopic Wedge Resection for Diffuse Lung Disease and Indeterminate Pulmonary Nodule

Video technology has revolutionized thoracoscopy dramatically, considerably increasing its indications. The clinical charts of patients who underwent a video-thoracoscopic procedure during a 6-year period were reviewed. Any patient in whom lung wedge resection for diffuse disease or an indeterminate nodule was performed met the inclusion criteria. Early and long-term outcomes were analyzed. A total of 310 thoracoscopic procedures were performed in the 250 patients reviewed. Of these patients, 60 presented with diffuse lung disease and 71 with an indeterminate pulmonary nodule. The total morbidity among diffuse disease patients was 5% (one intercostal vessel hemorrhage and two air leaks). Overall mortality for this group was 11% and was related to previous respiratory status and underlying disease. Patients not requiring preoperative mechanical ventilation ended up requiring it postoperatively, for a crossover rate of 23%. There was no morbidity or mortality in patients who did not require mechanical ventilation. The therapeutic impact index (defined as the total number of patients divided by the patients in whom initiation or withdrawal of specific treatment was due to the biopsy result) for diffuse lung disease was 0.9. Regarding lung nodule resection, early morbidity was present in one patient, who developed a persistent air leak. Late morbidity was present in three patients, who developed persistent intercostal pain. Total morbidity was 5.6%. No mortality was observed for this group. Nonanatomic wedge resection via video-thoracoscopy for diffuse pulmonary disease and indeterminate lung nodule is feasible using minimally invasive methods. Morbidity and mortality are related to the underlying disease and the respiratory status; they are not necessarily due to the procedure.     

Pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis

Although pseudoaneurysms are a rare complication of chronic pancreatitis, they are potentially serious both because of the events they can lead to and the diagnostic challenges they may pose. Historically, they used to be treated surgically, through ligation and/or resection; it was not until the last decade that scarcely invasive percutaneous endovascular procedures were introduced. This article reports the case of a patient with chronic pancreatitis presenting with severe upper digestive hemorrhage caused by the rupture of a pseudoaneurysm of the gastroduodenal artery. The patient was successfully treated using selective embolization.     

Use of a Roux Limb to Correct Esophagogastric Junction Fistulas after Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy (LSG) can be complicated, in the early postoperative course, by an esophagogastric junction (EGJ) leak with very serious consequences. A 48-year-old woman developed an EGJ leak 3 days after LSG surgery and was treated with conservative measures. Finally, 6 weeks after the original surgery, a Roux limb was brought to the EGJ and anastomosed side-to-end to the fistula. At the beginning, the Roux limb was the only functioning outlet and finally, 2 months later, both pathways (the gastric sleeve and the Roux-en-Y) are patent at 3 months after surgery. The Roux limb resolved a dangerous EGJ leak after a LSG.     

Pentafecta: a new concept for reporting outcomes of robot-assisted laparoscopic radical prostatectomy

Background

Widespread use of prostate-specific antigen screening has resulted in younger and healthier men being diagnosed with prostate cancer. Their demands and expectations of surgical intervention are much higher and cannot be adequately addressed with the classic trifecta outcome measures.

Objective

A new and more comprehensive method for reporting outcomes after radical prostatectomy, the pentafecta, is proposed.

Design, setting, and participants

From January 2008 through September 2009, details of 1111 consecutive patients who underwent robot-assisted radical prostatectomy performed by a single surgeon were retrospectively analyzed. Of 626 potent men, 332 who underwent bilateral nerve sparing and who had 1 yr of follow-up were included in the study group.

Measurements

In addition to the traditional trifecta outcomes, two perioperative variables were included in the pentafecta: no postoperative complications and negative surgical margins. Patients who attained the trifecta and concurrently the two additional outcomes were considered as having achieved the pentafecta. A logistic regression model was created to evaluate independent factors for achieving the pentafecta.

Results and limitations

Continence, potency, biochemical recurrence–free survival, and trifecta rates at 12 mo were 96.4%, 89.8%, 96.4%, and 83.1%, respectively. With regard to the perioperative outcomes, 93.4% had no postoperative complication and 90.7% had negative surgical margins. The pentafecta rate at 12 mo was 70.8%. On multivariable analysis, patient age (p = 0.001) was confirmed as the only factor independently associated with the pentafecta.

Conclusions

A more comprehensive approach for reporting prostate surgery outcomes, the pentafecta, is being proposed. We believe that pentafecta outcomes more accurately represent patients’ expectations after minimally invasive surgery for prostate cancer. This approach may be beneficial and may be used when counseling patients with clinically localized disease.     

Infections in patients with chronic renal failure and kidney transplant recipients in Brazil

Patients with chronic renal failure who are undergoing dialysis and kidney transplant recipients are susceptible to infection for several reasons. In this study, the profile of infections in patients with chronic renal failure and kidney transplant recipients treated at a hospital in northern Paraná, Brazil, from 2007 to 2009 was examined. The study involved 187 patients: 59 kidney transplant recipients and 128 patients undergoing dialysis. The frequency of infection was 25% (32/128) in dialysis patients and 8% (5/59) in transplant recipients (P = .008). Staphylococcus aureus was the most prevalent infectious agent, cultured from 27% (13/48) of samples, followed by Escherichia coli at 17% (8/48). All isolates of S aureus were sensitive to vancomycin and resistant to penicillin, and 43% were resistant to oxacillin. Most S aureus samples (43%) were isolated from cultures of blood samples. As for the E coli, 75% were resistant to cephalothin and 38% were resistant to sulfamethoxazole/trimethoprim. Most isolates of E coli (62%) were cultured from specimens of patients with suspected urinary tract infection.     

Simple intraoperative technique for minor dural gap repair using fibrin glue and oxidized cellulose

INTRODUCTION: Several methods have been proposed to achieve a watertight dural closure, including the use of fibrin sealant to reinforce sutures. We propose a fast technique using oxidized cellulose and fibrin glue to achieve firm and watertight closure of minor dural defects in supratentorial cranial surgery. TECHNICAL NOTE: Oxidized cellulose is cut to the shape of the dural defect and applied as an onlay graft. Fibrin sealant is then applied over the cellulose and the dural margins defect. The web conformation of oxidized cellulose avoids adhesion of fibrin glue to the underlying cortical surface of the brain. This technique has been applied in 45 of 467 supratentorial craniotomies during two consecutive years. The procedure was performed in few seconds. Postoperatively, three patients developed subgaleal fluid collection, which resolved conservatively in two cases. There were no other complications or reoperations. CONCLUSION: We used a piece of oxidized cellulose, reinforced by fibrin glue, as a sutureless graft with more ease and less technical demand than other techniques. The reported technique is a fast and valid alternative to small dural defect closure methods.     

Laparoscopy should be the approach of choice for acute appendicitis in the morbidly obese

BACKGROUND: The current study compared the outcome of morbidly obese patients undergoing laparoscopic versus open appendectomy. METHODS: We obtained data from the University HealthSystem Consortium (UHC) database on 1,943 morbidly obese patients who underwent appendectomy for acute or perforated appendicitis between 2002 and 2007. RESULTS: Compared to open appendectomy, laparoscopic appendectomy was associated with a shorter length of stay (3 vs 4 days) and a lower overall complication rate (9% vs 17%). Most notably, a lower rate of wound infection was noted (1% vs 3%). Within a subset analysis of morbidly obese patients who underwent appendectomy for perforated appendicitis, there was a higher overall complication rate (27% vs 18%) and cost ($16,600 vs $12,300) in the open appendectomy group. CONCLUSION: In the morbidly obese, laparoscopic appendectomy performed for acute and perforated appendicitis is associated with a shorter length of stay and lower morbidity and costs. Laparoscopic appendectomy should be the procedure of choice for the treatment of acute appendicitis in the morbidly obese population.     

Benefit of Neoral C2 monitoring in de novo cardiac transplant recipients receiving basiliximab induction

BACKGROUND: For cyclosporine (CsA), 2-hr postdose level (C2) is the best single time point predictor of the area under the curve and a critical measure for effective dosing. The therapeutic CsA microemulsion (Neoral) C2 range in de novo heart transplant patients remains to be determined. PURPOSE: The purpose of this study was to determine the efficacy of CsA C2 monitoring in de novo heart transplant patients receiving basiliximab induction. METHODS: This prospective, multicenter, randomized study enrolled 87 adult heart transplant recipients stratified according to 4 to 6 hrs posttransplant serum creatinine less than or equal to 170 micromol/L (cohort A) or more than 170 micromol/L (cohort B). Patients in cohort A were randomized into three C2 ranges (A1: "high" n=25, 1600-1800 ng/mL; A2: "intermediate" n=27, 1400-1600 ng/mL; and A3: "low" n=24, 1200-1400 ng/mL). Patients in cohort B were randomized into intermediate (n=5) and low C2 (n=6). Target ranges were progressively lowered after 1 month. Immunosuppression included basiliximab, Neoral, mycophenolate mofetil, and corticosteroids. Endpoints were acute rejection and renal function. RESULTS: The incidence of acute rejection at 12 months was 44% in group A1, 41% in group A2, 33% in group A3, and 27% in cohort B. Pretransplant and 12-month creatinine clearance (mL/min) were group A1, 72+/-25 and 64+/-24; group A2, 81+/-32 and 68+/-25; group A3, 91+/-28 and 86+/-26; and cohort B, 62+/-28 and 79+/-37. CONCLUSION: These results suggest that C2 monitoring is safe in de novo heart transplant patients. A low Neoral C2 range in combination with basiliximab induction resulted in preserved renal function without increased risk of acute rejection.
