Laparoscopic radical prostatectomy: The new gold standard?

Radical prostatectomy is the reference treatment for localized prostate cancer. The minimal invasive approach is gaining support in a large number of centers around the world because the laparoscopic approach seems to maintain the oncological control of open surgery with added benefits for the patient. In this paper, the main aspects of the different laparoscopic approaches, their benefits, difficulties, complications, and results are described and compared with the open radical prostatectomy. A critical review of the literature on radical prostatectomy comparing the open and laparoscopic techniques and the differences between each approach was done.     

Gastrostomy insertion in children: percutaneous endoscopic or percutaneous image-guided?

Background/Purpose

Gastrostomy insertion in children can be performed in many ways, but which is the best technique remains uncertain. This study evaluates the outcome of percutaneous endoscopic gastrostomy (PEG) and image-guided gastrostomy (IG).

Methods

We reviewed children who had either PEG (n = 136) inserted by pediatric surgeons or IG (n = 195) inserted by interventional radiologists in our hospital between May 2004 and July 2008. Gastrostomy-related complications were given scores ranging from 20 for major complications (eg, peritonitis, gastrointestinal bleed, and visceral injury) to 1 for minor (eg, site infection and tube migration), and total score per month of follow-up was calculated per patient.

Results

Conversion to laparoscopic or open gastrostomy was more frequent in PEG versus IG (P = .001). Fewer PEG patients (28%) had complications than did IG (47%) (P = .001). One PEG patient developed a gastrocolic fistula. In the IG group, 2 patients had transverse colon puncture, 1 had intraperitoneal tube detachment, and 1 had upper gastrointestinal bleeding. When scored and adjusted by length of follow-up, PEG had lower scores compared with IG, indicating a better outcome (P = .03). These findings were supported by zero-inflated Poisson regression analysis.

Conclusion

Major complications were rare and observed more frequently after IG. Minor complications were observed in both procedures but were significantly less common in PEG.     

Laparoscopic repair of colonoscopic perforation: a new standard?

Background  

Scientific evidence demonstrating interest in the laparoscopic approach for surgical repair of colonoscopic perforations is still lacking. The authors retrospectively reviewed the records of 43 patients who suffered from colonic perforations after colonoscopy between 1989 and 2008 in two tertiary centers in order to compare the results of the laparoscopic and the open approaches to repair.     

Single Port Access (SPA™) gastrostomy tube in patients unable to receive percutaneous endoscopic gastrostomy placement

Background  Access procedures for alimentation have been performed both endoscopically and surgically. In those patients in whom endoscopic tubes cannot be placed, the minimally invasive approach is a viable alternative. To minimize incisions and their sequelae, we have developed a single port access (SPA) technique in which minimal access surgery can be done through one portal of entry, often the umbilicus. Methods  We have used the SPA technique to place gastric feeding tubes in patients who are not candidates for PEG tubes due to supraglottic stenosis. We reviewed our experience in the first five procedures we performed. Results  In all five patients a gastrostomy tube was placed laparoscopically via an umbilical incision and a left-upper-quadrant tube insertion point. Mean operative time was 44 min. All patients began tube feeds on postoperative day 1. Conclusion  We present the first series of five SPA gastric tube placements, offering a viable alternative to PEG or open placement.     

Laparoscopic adrenalectomy: alternative or new standard?

Laparoscopy has become a standard approach for adrenalectomy because of its safety, low invasiveness, and less demanding technical nature and the readily removable size of tumor through trocar incision. Comparative studies between open and laparoscopic adrenalectomy document less blood loss, shorter hospital stay, and lower incidence of complication. These reports also show that the patients have less pain, use fewer narcotics postoperatively, and have quicker resumption of oral intake after surgery with the laparoscopic approach. The techniques for laparoscopic adrenalectomy started with the transperitoneal approach and developed into the retroperitoneal approach. Further technical development and recognition yielded three transperitoneal and two retroperitoneal approaches. Characteristics of each approach are discussed. Due to technical developments and experiences in laparoscopic surgery, application of the laparoscopic approach has been expanded to include excision for adrenal cancer and laparoscopic partial adrenalectomy for bilateral pheochromocytoma in certain cases and in selected institutes.     

Laparoscopic nephrectomy: new standard of care?

OBJECTIVE: The pace of implementation of a laparoscopic nephrectomy programme is affected by factors including surgical expertise, case load, learning curves and outcome audits. We report our experience in introducing a laparoscopic nephrectomy programme over a 3-year period. METHODS: From January 2001 to December 2003, 187 nephrectomies were performed (105 by conventional surgery, 82 by laparoscopy). Hand-assisted laparoscopy was used predominantly. The indications for surgery, factors affecting the approach and outcome parameters were studied. A cost comparison was made between patients with similar-sized renal tumours undergoing laparoscopic versus open surgery. RESULTS: Most operations were performed for malignancy in both the open (70%) and laparoscopic (67%) surgery groups. The laparoscopic approach was most commonly used in upper tract transitional cell cancers (TCCs; 70% of 30 patients) and benign pathologies (49% of 35 patients), followed by radical nephrectomies (34% of 99 patients) and donor nephrectomies (44% of 23 patients). There was a rapid rise in laparoscopic surgeries, from 30% in 2001 to 58% in 2002. The median hospital stay was 5.8 days in the laparoscopic group and 8.1 days in the open surgery group. The procedure cost for laparoscopic surgery was 4,943 dollars compared with 4,479 dollars for open surgery. However, due to a shorter hospital stay, the total hospital cost was slightly lower in the laparoscopic group (7,500 dollars versus 7,907 dollars). CONCLUSION: The laparoscopic approach for various renal pathologies was quickly established with a rapid increase in the number of laparoscopic procedures.     

Laparoscopic cholecystectomy for elderly patients: gold standard for golden years?

HYPOTHESIS: Laparoscopic cholecystectomy (LC) has known physiological benefits and positive socioeconomic effects over the open procedure. Although recent studies have questioned the technique's efficacy in elderly patients (>65 years), we hypothesize that LC is safe and efficacious in that patient group. METHODS: Five thousand eight hundred eighty-four consecutive patients (mean age, 40 years; 26% male) underwent an attempted LC (conversion rate, 5.2%) from 1991 to 2001 at a teaching institution. Of these, 395 patients (6.7%) were older than 65 years. Analysis included patient age, sex, American Society of Anesthesiologists classification, conversion rate, morbidity, mortality, and assessment of results over time. RESULTS: Elderly patients were predominantly male (64%). Septuagenarians had a 40% incidence of complicated gallstone disease, such as acute cholecystitis, choledocholithiasis, or biliary pancreatitis, and octogenarians had a 55% incidence. Overall mortality was 1.4%. The conversion rate was 17% for the first 5 years of the study period and 7% for the second half. The conversion rate was 22% for patients with complicated disease and 2.5% for patients with chronic cholecystitis. Average hospital stay decreased from 10.2 days to 4.6 days during the first and second half of the study period, respectively. CONCLUSIONS: The results of LC in patients aged 65 to 69 years are comparable with those previously reported in younger patients. Patients older than 70 years had a 2-fold increase in complicated biliary tract disease and conversion rates, but a low mortality rate (2%) compared with results of other authors (12%), despite an increase in American Society of Anesthesiologists classification. Increased technical experience with LC favorably affected outcomes over time. Early diagnosis and treatment prior to onset of complications are necessary for further improvement in the outcomes of elderly patients undergoing LC.     

Treatment of ruptured abdominal aneurysms with stent grafts: a new gold standard?

Ruptured abdominal aortoiliac aneurysms, when treated with open surgical repair, have high morbidity and mortality rates. Since 1994, the authors have used endovascular approaches to treat this entity. Patients with presumed ruptured aortoiliac aneurysms were treated with restricted fluid resuscitation (hypotensive hemostasis), transport to the operating room, placement under local anesthesia of a brachial or femoral guide wire into the supraceliac aorta, and arteriography. If aortoiliac anatomy was suitable, an endovascular graft (stent-graft) repair was performed. If the anatomy was unfavorable, standard open repair was performed. Only if circulatory collapse occurred was a supraceliac balloon placed and inflated using the previously positioned guidewire. Of 35 patients treated in this manner, 29 underwent endovascular graft repair, and 6 required open repair. Four patients died within 30 days (operative mortality rate, 11%). Only 10 patients required supraceliac balloon control. Endovascular grafts, when combined with hypotensive hemostasis and other endovascular techniques including proximal balloon control, may improve treatment outcomes with ruptured abdominal aortoiliac aneurysms. The authors believe these techniques will become widely used for the treatment of ruptured aneurysms.     

Buccal mucosal urethroplasty: is it the new gold standard?

Whilst techniques for urethral reconstruction have developed in the past few decades the quest for an ideal substitute continues. We critically review the literature on buccal mucosal grafts for substitution urethroplasty, to determine the efficacy and complications arising from its use. Buccal mucosal grafts have proved to be a versatile substitute for strictures attributable to a wide range of causes. Placing the graft dorsally appears to be more successful than ventrally and was successful in 96% of cases; after treating complex urethral strictures with two-stage procedures about a quarter of patients required a revision after the first stage with fewer complications then when skin was used as a substitute. Thus, buccal mucosa is most likely to become the new gold standard for substitution urethroplasty and longer term results with its use are eagerly awaited.     

Vacuum assisted wound closure in postoperative periprosthetic groin infections: a new gold standard?

AIM: This study was designed to control the results of conservative treatment using vacuum assisted wound closure (VAWC) applied exclusively to cases of deep groin infections with involvement of alloplastic graft material. METHODS: During a 2 year period 10 patients with 11 deep inguinal infections involving alloplastic graft material were treated with supportive VAWC. Intraoperative management included extensive debridement, sartorius myoplastic and VAWC application. A retrospective case-note review was performed. Variables comorbidity, surgical management of the infection, microbiological results, complications and Doppler results were analysed. RESULTS: Six early graft infections (< 30 days after implantation) and 5 late infections were treated. In 3 cases (27.3%) the infected graft material was replaced by a silver-coated Dacron prosthesis. The mean duration of VAWC was 16+/-7.7 days; postoperative mean hospital stay was 25.3+/-8.5 days. Mean postoperative follow-up was 13.1 months with no procedure-related mortality. CONCLUSION: Even in the presence of synthetic vascular graft material, negative pressure therapy can greatly simplify challenging wound healing problems under maintenance of the alloplastic grafts. These preliminary results demonstrate the safety and effectiveness of VAWC for the treatment of deep alloplastic graft infections.     

Laparoscopic radical nephrectomy for T1 renal cancer: the gold standard? A comparison of laparoscopic vs open nephrectomy

OBJECTIVE: To evaluate the complication rate and clinical follow-up of patients treated for T1 renal cancer by open or laparoscopic nephrectomy at the same institution, as this approach appears to be attractive for treating small renal cancers. PATIENTS AND METHODS: Between 1995 and 2002, 39 patients underwent retroperitoneal laparoscopic and 26 transperitoneal open radical nephrectomy for T1 renal cancer (TNM 1997). Variables before during and after surgery, e.g. cancer recurrence, were compared between the groups. RESULTS: There were no differences between the laparoscopic and open groups in age, sex ratio, weight, height, fitness score, operative duration (134 vs 133 min), minor or major complications, tumour diameter, Fuhrman grade or length of follow-up. Patients who underwent laparoscopic surgery had less blood loss (133 vs 357 mL, P < 0.001), less need for transfusion (none vs 150 mL, P = 0.04), a lower consumption of analgesia drugs, and shorter hospitalization (5.5 vs 8.8 days, P < 0.001). With a mean follow-up of 20.4 months there was no recurrence or tumour progression. CONCLUSION: Laparoscopic radical nephrectomy for patients with T1 renal cancer is a safe, reliable procedure that decreases hospitalization time and bleeding, and ensures the same cancer control as open nephrectomy.     

Classification and diagnosis of prostatitis: a gold standard?

The National Institutes of Health Classification System for prostatitis has now been accepted by the North American and International urology community. This categorization system consists of category I (acute bacterial prostatitis), category II (chronic bacterial prostatitis), category III (chronic prostatitis/chronic pelvic pain syndrome - CP/CPPS) and category IV asymptomatic inflammatory prostatitis. The evaluation of a patient with category I and category II bacterial prostatitis consists of history and physical examination and urine culture for lower urinary tract localization cultures, respectively. The clinical tests for the evaluation of CP/CPPS can be classified as mandatory, recommended and optional. Mandatory evaluations include history and physical examination, urinalysis and urine culture. Recommended evaluations include lower urinary tract localization tests, symptom index, flow rate, residual urine determination and urine cytology. Optional evaluations include semen analysis and culture, urethral swab, urodynamics, cystoscopy, imaging, and prostate specific antigen determination. The physician must individualize a rational diagnostic strategy for each patient. There is no 'gold standard' for the diagnosis and evaluation of patients presenting with prostatitis.
