Comparison of robotic-assisted vs conventional laparoscopy for extraperitoneal paraaortic lymphadenectomy.

OBJECTIVE: To evaluate the perioperative outcomes of robotic-assisted extraperitoneal paraaortic lymphadenectomy for locally advanced cervical cancer and to compare to a previous series of patients from our institution undergoing the same procedure by conventional laparoscopy. METHODS: 17 patients with locally advanced cervical cancer (FIGO stages IB2, IIA2 and IIB-IVA) underwent pretherapeutic extraperitoneal paraaortic lymphadenectomy by robotic-assisted laparoscopy. Perioperative outcomes including age, BMI, FIGO stage, operating time, blood loss, complications and length of hospital stay were compared to a series of 83 patients from our institution undergoing the same procedure by conventional laparoscopy. RESULTS: The median values for operating time and hospital days for the robotic-assisted and conventional laparoscopy groups were 150 vs. 150 min and 2 vs 2 days, respectively. In the robotic group, blood loss was lower (90 vs 20 ml, p<0.05) and more aortic nodes were removed (14 vs 17 nodes, p<0.05). Docking time was 7 min (range 3-15). There were no intraoperative complications. There were no differences for postoperative complications (17.6% vs 8.4%). CONCLUSION: Robotic-assisted and conventional laparoscopy provide similar perioperative outcomes other than lower blood loss and higher number of aortic nodes removed (both without clinical impact) in robotic patients for the performance of extraperitoneal paraaortic lymphadenectomy in patients with locally advanced cervical cancer. We believe that robotic surgery is an additional tool to perform the same surgical procedure. HIGHLIGHTS: Robotic-assisted and conventional laparoscopic extraperitoneal paraaortic lymphadenectomy provide similar perioperative outcomes.

Location of aortic node metastases in locally advanced cervical cancer.

BACKGROUND: To assess the location of aortic node metastasis in patients with locally advanced cervical cancer undergoing extraperitoneal aortic lymphadenectomy to define the extent of the aortic lymphadenectomy. MATERIAL AND METHODS: Between August 2001 and December 2010, 100 consecutive patients with primary locally advanced cervical cancer underwent extraperitoneal laparoscopic aortic and common iliac lymphadenectomy. The location of aortic node metastases, inframesenteric or infrarenal was noted. RESULTS: The mean number±standard deviation (SD) of aortic nodes removed was 15.9 ± 7.8 (range 4-62). The mean number ± SD of inframesenteric (including common iliac) nodes removed was 8.8 ± 4.5 (range 2-41) and the mean number ± SD of infrarenal nodes removed was 7.8 ± 4.1 (range 2-21). Positive aortic nodes were observed in 16 patients, and in 5 (31.2%) of them the infrarenal nodes were the only nodes involved, with negative inframesenteric nodes. CONCLUSION: Inframesenteric aortic nodes are negative in the presence of positive infrarenal nodes in about one third of patients with locally advanced cervical cancer and aortic metastases.

Robotic surgery for endometrial cancer: comparison of perioperative outcomes and recurrence with laparoscopy, vaginal/laparoscopy and laparotomy.

INTRODUCTION: Comparison of perioperative outcomes and recurrence in patients undergoing primary surgical treatment for endometrial cancer by robotics, laparoscopy, vaginal/laparoscopy, or laparotomy approaches. METHODS: Prospective analysis of 67 patients undergoing robotic surgery for endometrial cancer between March 2004 and December 2007. Comparison was made with similar patients operated between November 1999 and December 2006 by laparoscopy (37 cases), laparotomy (99 cases) and vaginal/laparoscopy approach (vaginal hysterectomy, bilateral adnexectomy/laparoscopic lymphadenectomy) (47 cases) and matched by age, body mass index (BMI), histological type and International Federation of Gynecologists and Obstetricians (FIGO) staging. RESULTS: Mean operating times for patients undergoing robotic, laparoscopy, vaginal/laparoscopy or laparotomy approach were 181.9, 189.5, 202.7 and 162.7 min, respectively (p = 0.006); mean blood loss was 141.4, 300.8, 300.0 and 472.6 ml, respectively (p <0.001); mean number of nodes was 24.7, 27.1, 28.6, and 30.9, respectively (p = 0.008); mean length of hospital stay was 1.9, 3.4, 3.5 and 5.6 days, respectively (p < 0.001). There were no significant differences in intra- or postoperative complications among the four groups. The conversion rate was 2.9% for robotics and 10.8% for the laparoscopy group (0.001). There were no differences relative to recurrence rates among the four groups: 9%, 14%, 11% and 15% for robotics, laparoscopy, vaginal/laparoscopy, and laparotomy, respectively. CONCLUSION: Robotics, laparoscopy and vaginal/laparoscopy techniques are preferable to laparotomy for suitable patients with endometrial cancer. Robotics is preferable to laparoscopy due to a shorter hospital stay and lower conversion rate and preferable to vaginal/laparoscopy due to a reduced hospitalization.

Consensus of the SEPG on depression in the elderly.

BACKGROUND: The limitation of clinical-epidemiological know-how and evidence regarding therapeutic efficiency in depression among the elderly and extremely elderly patients has given rise to an excessive variety of practices in clinical care of these patients in the Spanish health system. The Spanish Society of Psychogeriatrics (SEPG) has raised the question of the need to unify criteria through a structured approach based on professional consensus. OBJECTIVES: To develop an expert consensus of clinical recommendations to improve the clinical treatment of depression in elderly patients in Spain, sponsored by the Spanish Society of Psychogeriatrics (SEPG). METHODS: Modified Delphi Consensus, in two rounds. The study was conducted in four phases: 1) constitution of a Scientific Committee, project promoter and responsible for bibliographic review and formulation of recommendations for discussion 2) constitution of a multicenter Panel of Experts with representatives from this specialist field 3) postal survey comprised of two rounds, with interim processing of opinions and a report for the experts and 4) discussion of results during an on-site meeting of the Scientific Committee. RESULTS: The survey evaluation was completed by 61 experts consulted, in two rounds. In the first round, consensus was reached in 39 of the 54 questions analyzed. Following interaction by the panel, this consensus was increased to a total of 46 survey items (85% of the proposed contents). It was impossible to obtain a sufficiently unanimous consensus on the remaining 8 questions, either due to differences of opinion among the professionals or a lack of established criterion in most of the experts. CONCLUSIONS: A full list of criteria and clinical recommendations for the purpose of rationalizing the treatment of depression in elderly patients and reducing excessive variability in clinical practice is presented. The recommendations are qualified in accordance with the degree of consensus of the professionals endorsing them and can be considered valid until new scientific information becomes available that justifies their review.

Metastatic and recurrent adenocarcinoma of the uterine cervix: a long-term survival of 16 years.

PURPOSE OF INVESTIGATION: Recurrent metastatic adenocarcinoma of the cervix is associated with an extremely poor prognosis. Treatment options for recurrent disease are limited and cure is extremely rare. CASE REPORT: We report a case of a 43-year-old patient with Stage IB adenocarcinoma of the cervix. She had multiple metastatic recurrence episodes salvaged with several radical surgeries, external and intraoperative irradiation, and chemotherapy over a survival period of 16 years. CONCLUSION: We conclude that long-term multi-modal salvage treatment may achieve longer survival in rare cases with recurrent metastatic adenocarcinoma of the cervix.

Robotic surgery in gynecology.

Robotic technology is nothing more than an enhancement along the continuum of laparoscopic technological advances and represents only the beginning of numerous more forthcoming advances. It constitutes a major improvement in the efficiency, accuracy, ease, and comfort associated with the performance of laparoscopic operations. Instrument articulation, downscaling of movements, absence of tremor, 3-D image, and comfort for the surgeon, assistant and scrub nurse are all new to the practice of laparoscopy. In our hands, robotic operative times for simple and radical hysterectomy are shorter than those obtained by conventional laparoscopy. Robotic technology is preferable to conventional laparoscopic instrumentation for the surgical treatment of gynecologic malignancies and most operations for benign disease of certain complexity such as hysterectomy myomectomy, and invasive pelvic endometriosis.

Feasibility of early discharge after acute Q wave myocardial infarction in patients not receiving thrombolytic treatment.

OBJECTIVES: The purpose of this study was to analyze the feasibility of early discharge (4 days) after acute myocardial infarction in patients not receiving thrombolytic therapy by first identifying predictors of short-term prognosis and then testing the derived risk profile in an independent cohort of patients. BACKGROUND: Previous studies have shown that early discharge after acute myocardial infarction is possible. However, physicians are reluctant to shorten the standard 7- to 10-day hospital stay, presumably because of difficulty in selecting low risk patients. METHODS: From January 1985 to November 1986, 358 patients with acute myocardial infarction who did not receive thrombolytic therapy were screened. Those with a Q-wave infarction showing no complications on day 4 were considered candidates for early discharge and were transferred to the ward for a mean of 12 days. During this period, we looked for any event (cardiac or noncardiac) that would have prompted readmission if the patient had been previously discharged. Univariate and multiple regression analysis were performed to identify predictors of these events among 25 baseline variables. The derived risk profile was tested in an independent validation cohort. RESULTS: One hundred five (29.3%) of the 358 patients were free of symptoms on day 4, and 29 (27.6%) had at least one cardiac event, including four deaths and one reinfarction. Multivariate analysis selected diabetes, ejection fraction < 40% and age as independent predictors of events. Using the risk profile, 18 (13.2%) of the 136 validation cohort patients were categorized as low risk, and only 1 of them had a major event (progressive angina). Sensitivity for the risk profile was high (91%), but specificity was low (34%). CONCLUSIONS: The use of simple clinical variables may allow the safe reduction of hospital stay after infarction in selected patients. However because the proportion of candidates for early discharge is small (12.6%), it seems unlikely that the current policies on length of hospital stay will change in the near future.

Robotic nerve-sparing radical hysterectomy.

AIM: The aim of this paper was to describe the robotic nerve-sparing technique and review the most recent data in the literature on this surgical approach. METHODS: Presentation of anatomical aspects regarding the nerve-sparing technique, besides discussion of the surgical steps as performed in our institution. RESULTS: Robotic-assisted nerve-sparing radical hysterectomy is a feasible approach for the treatment of cervical cancer patients, with remarkable advantages in terms of ergonomy, articulated movements and image magnification. All these features contribute for identification and preservation of the pelvic innervation, reducing the risk of surgical sequelae. CONCLUSION: Robotic nerve-sparing technique can be incorporated as a standard care without compromising radicality.

Primary surgery for stage IB-IIA cervical cancer, including short-term and long-term morbidity and treatment in pregnancy.

Radical hysterectomy and pelvic lymphadenectomy are indicated for the treatment of cervical carcinoma that is localized clinically to the cervix and upper vagina. Intraoperative complications have been reported in 1.1%-7.4% of patients. Long-term complications include bladder dysfunction (2% at 3 years), urinary fistula (vesical, 0.8%; ureteral, 1.2%), stress urinary incontinence (29%), ureteral stricture (1%), rectal dysfunction (80%), severe constipation (5.3%), lymphocysts (20% by ultrasonography; 2% clinically), and lymphedema (10%). The operative mortality is 0.7%. The 5-year survival rate for patients with stage IB disease is 85.7% and for stage IIA is 69.6%. The recurrence rate is 27.2%. Recurrences are distributed equally between the pelvis and extrapelvic sites. Radical hysterectomy is the treatment of choice for pregnant patients with early cervical cancer. It affords termination or delivery of the pregnancy at the same time that the treatment is provided. For patients with stage I disease treated with radical hysterectomy, the survival rate is 92.1%.

Disabling angina pectoris with normal coronary arteries in patients undergoing long-term hemodialysis.

Reports of patients undergoing long-term hemodialysis presenting with angina pectoris have usually shown severe coronary atherosclerosis. We studied a series of nine patients undergoing regular maintenance dialysis referred for incapacitating angina. Of them, four had strictly normal coronary angiograms. The patients with normal angiograms were all females who were significantly younger (p less than 0.05) and had more severe hypertension and higher left ventricular wall stress than patients showing coronary artery lesions. Anemia and increased myocardial oxygen consumption due to high blood pressure may explain the syndrome of angina pectoris in the presence of long-term dialysis in patients with normal coronary arteries. The prevalence of this association cannot be ascertained unless prospective studies are conducted. However, our data suggest that it might not be an uncommon finding.

Survival with painless strongly positive exercise electrocardiogram.

To determine the prognosis of patients with painless strongly positive exercise electrocardiogram, the 6-year cumulative survival rate was computed for 298 medically treated patients who terminated their exercise test with or without angina. All had horizontal or downsloping ST depression greater than or equal to 2 mm during a treadmill exercise test according to the standardized multistage Bruce protocol. Of the 298 patients, 119 terminated the exercise test because of dyspnea or fatigue and 179 stopped because of angina. Among the 119 patients without angina, there were 18 deaths, 16 from coronary artery disease (CAD), of which 8 occurred suddenly. Among the 179 patients with exercise-induced angina, 36 died, 33 from CAD, of which 13 were sudden deaths. The overall 6-year survival rate was 85 +/- 3% for patients without angina and 80 +/- 3% in those with angina (p less than 0.05). However, patients without angina achieved a significantly longer duration of exercise and had higher maximal heart rate and systolic blood pressure during exercise. In both groups, survival decreased with decreasing duration of exercise. In patients without angina, the 6-year survival rate was 97 +/- 3% in those achieving stage IV (greater than or equal to 541 s), 87 +/- 4% in stage III (361 to 540 s), 64 +/- 13% in stage II (181 to 360 s) and 60 +/- 15% in stage I (less than or equal to 180 s).(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence and prognosis after a first nontransmural myocardial infarction.

Prevalence, prognosis, and coronary anatomy associated with nontransmural myocardial infarction (MI) were prospectively assessed in 458 consecutive men admitted to our coronary care unit with a first MI. Cardiac catheterization was performed in 402 of the 436 survivors within 1 month of the acute event. Mean follow-up was 33 months (range 5 to 72). Nontransmural MI was diagnosed in 28 patients (6%). These patients were younger (46 +/- 10 versus 51 +/- 7 years, p less than 0.001) and had lower peak creatine kinase values (601 +/- 319 versus 1,141 +/- 923 U, p less than 0.01) and better ejection fraction (63 +/- 8 versus 46 +/- 14, p less than 0.001) than did their counterparts. Survivors of nontransmural MI also had fewer affected arteries (p less than 0.001) and a lower prevalence of total or subtotal occlusion (greater than 90%) in the involved artery (p less than 0.01). Mortality in the acute phase and long-term survival at 4 years (Kaplan-Meier) in patients with nontransmural MI (94%) were similar to those in patients with transmural MI (90%). The occurrence of new nonfatal coronary events was also similar in both groups of MI survivors. Thus, in the absence of symptoms, more aggressive management to improve survival does not seem warranted after nontransmural MI.

Significance of Q-wave regression after transmural acute myocardial infarction.

A total of 313 consecutive patients was studied to assess the prevalence and prognostic implications of Q-wave loss after transmural acute myocardial infarction. Heart catheterization, including single-plane left ventriculography and selective coronary arteriography, was performed before hospital discharge. After a mean follow-up of 65 (1 to 100) months, 34 patients (11%) lost their Q waves. The time interval from the acute event to the first electrocardiogram showing Q-wave disappearance was 14 (1 to 32) months. Peak creatine kinase value was significantly higher in patients who retained their Q waves than in those who lost them (1,121 +/- 813 vs 779 +/- 464 IU, respectively, p less than 0.05). Severity of coronary artery disease, as judged by the number of diseased arteries and the number of arteries with total or subtotal occlusion, was similar in both groups. However, patients showing Q-wave regression had lower left ventricular end-diastolic pressure, higher ejection fraction and fewer abnormally contracting segments than their counterparts (12 +/- 6 vs 15 +/- 7 mm Hg, p less than 0.05; 53 +/- 11 vs 44 +/- 14%, p less than 0.001; 1 +/- 1 vs 2 +/- 1 segments, p less than 0.001, respectively). In addition, no patient with normalized electrocardiogram presented with left ventricular aneurysm. Although differences in mortality, nonfatal reinfarction and new onset of angina between the 2 groups were not significant, congestive heart failure was prevalent among patients with permanent Q waves (23 vs 6%, p less than 0.05). Our findings suggest that Q-wave loss after AMI may be related to a smaller infarct size.

Myocardial infarction with normal coronary arteries: a prospective clinical-angiographic study.

The association of myocardial infarction with normal coronary arteries was analyzed prospectively. A series of 259 consecutive men aged 60 years or less underwent selective coronary angiography 30 days after a definite infarct. Coronary arterial lesions were documented in 251 patients, normal coronary arteries in the remaining 8. The latter patients had a significantly lower (p less than 0.001) mean age than the former; no patient older than 50 years had patent coronary arteries, whereas 5 of the 11 patients under age 35 had normal arteries. The prevalence of risk factors was similar in both groups of patients. Although there were no group differences in infarct size or location, patients with normal coronary arteries had a higher ejection fraction (p less than 0.01) and a lower left ventricular end-diastolic pressure (p less than 0.05). A previous history of angina or infarction and the occurrence of new coronary events were confined to patients with coronary arterial lesions. The clinical course of patients presenting with normal angiograms was uneventful. Transient coronary occlusion, the most likely mechanism of infarction in this group of patients, could not be ascribed to either spasm or platelet hyperactivity.

Office management of ovarian cysts.

Ovarian cysts are detected in female patients of all ages. The patient's age, the size of the cyst, and the ultrasound appearance are helpful in determining which ovarian cysts necessitate observation and which necessitate surgical excision. The cancer antigen 125 level alone does not help to distinguish between benign and malignant ovarian cysts. The combination of benign findings on pelvic examination, a benign ultrasound appearance, and a cancer antigen 125 level within normal limits indicates a benign origin in practically all cases.

Intentional ureteral ligation in advanced pelvic malignant disease.

It is now widely accepted that debulking operative resections can provide effective palliation for some patients with advanced pelvic malignancy, particularly with those malignancies originating in the ovary. Some of these radical operations require the resection of long segments of the ureter and portions of the bladder. Although there is a variety of techniques that can be used in this situation to restore the continuity of the urinary tract, in some instances a simple ureteral ligation may represent the best method of managing the "short ureter." In our experience with 23 patients who underwent intentional ureteral ligation, the procedure was found to be safe, expeditious, and beneficial in managing some of the complex problems associated with advanced pelvic malignant disease.
