RESUMO

PURPOSE: Penile carcinoma is a rare but mutilating malignancy. In this context, partial penectomy is the most commonly applied approach for best oncological results. We herein propose a simple modification of the classic technique of partial penectomy, for better cosmetic and functional results. TECHNIQUE: If partial penectomy is indicated, the present technique can bring additional benefits. Different from classical technique, the urethra is spatulated only ventrally. An inverted "V" skin flap with 0.5 cm of extension is sectioned ventrally. The suture is performed with vicryl 4-0 in a "parachute" fashion, beginning from the ventral portion of the urethra and the "V" flap, followed by the "V" flap angles and than by the dorsal portion of the penis. After completion of the suture, a Foley catheter and light dressing are placed for 24 hours. CONCLUSIONS: Several complex reconstructive techniques have been previously proposed, but normally require specific surgical abilities, adequate patient selection and staged procedures. We believe that these reconstructive techniques are very useful in some specific subsets of patients. However, the technique herein proposed is a simple alternative that can be applied to all men after a partial penectomy, and takes the same amount of time as that in the classic technique. In conclusion, the "parachute" technique for penile reconstruction after partial amputation not only improves the appearance of the penis, but also maintains an adequate function.

RESUMO

OBJECTIVE: No consensus has yet been established regarding the best minimally invasive access for radical ablation of renal tumors. Our objective was to prospectively compare the surgical results and oncologic management of two currently used endoscopic techniques. MATERIALS AND METHODS: Over a four-year period, 50 patients with renal tumors and clinical stage T1b-T2, smaller than 12 cm, underwent a radical nephrectomy at two reference institutions, 25 underwent retroperitoneoscopic radical nephrectomy (RRN) and 25 a hand-assisted laparoscopic radical nephrectomy (HALRN). Mean follow-up of both cohorts was 50 months. Operative parameters and oncological management were compared. RESULTS: The mean operative time was 180 min in RRN and 108 min in HALRN (p < 0.001). The time required to access the renal pedicle in RRN was 30 min. and in HALRN 40 min., Learning curve was shorter in HALRN than RRN. Mean blood loss was 100 mL in RRN and 242 mL in HALRN. Mean incision size for specimen retrieval in RRN was 6.5 cm and in HALRN 7.5 cm. One patient with intra operative occurrence of ascites and subsequent pathological stage pT2N0M0 grade 3 operated via HALRN, had neoplasic implants in the Hand-port incision 3 months after surgery followed by death 4 months after recurrence. One patient, with pathological stage pT3N0M0 grade 3 in RRN had metastasis after 36 months. CONCLUSION: Both, RRN and HALRN techniques are accepted minimally invasive options for endoscopic radical nephrectomy with equivalent long term oncological outcome in the treatment of renal tumors.

RESUMO

INTRODUCTION: Two positions have been reported for ureteroscopy (URS): dorsal lithotomy (DL) position and dorsal lithotomy position with same side leg slightly extended (DLEL). The aim of the present study was to compare the outcomes associated with URS performed with patients in DL vs. DLEL position. MATERIALS AND METHODS: A total of 98 patients treated for ureteral calculi were randomized to either DL or DLEL position during URS, and were prospectively followed. Patients, stone characteristics and operative outcomes were evaluated. RESULTS: Of the 98 patients included in the study, 56.1% were men and 43.9% women with a mean age of 42.6 +/- 16.8 years. Forty-eight patients underwent URS in DL position and 50 in DLEL position. Patients' age, mean stone size and location were similar between both groups. Operative time was longer for the DL vs. DLEL group (81.0 vs. 62.0 minutes, p = 0.045), mainly for men (95.2 vs. 63.9 minutes, p = 0.023). Mean fluoroscopy use, complications and success rates were similar between both groups. CONCLUSIONS: Most factors associated with operative outcomes during URS are inherent to patient's condition or devices available at each center, and therefore cannot be changed. However, leg position is a simple factor that can easily be changed, and directly affects operative time during URS. Even though success and complication rates are not related to position, placing the patient in dorsal lithotomy position with an extended leg seems to make the surgery easier and faster.

RESUMO

INTRODUCTION: A wet colostomy can be done when the simultaneous diversion of fecal and urine streams are necessary. Laparoscopic access is gaining space in urinary diversion procedures. The aim of the present study was to present the technique and results of the first case reported of a video-assisted double-barreled wet colostomy. PATIENT AND METHODS: In this article, we report a case of a 50-year-old woman with actinic complex urinary and fecal fistula, treated through a retroperitoneoscopic double-barreled wet colostomy. Only the left kidney had function, so she was treated by video endoscopic retroperitoneal dissection of the left ureter, preplanned transverse 5-cm incision for exteriorization of left colon and ureter, extracorporeal section of the left colon with a linear stapler, extracorporeal antireflux ureterocolonic anastomosis, and maturation of the stoma 10 cm proximal to the end of the proximal colonic loop. RESULTS: Operative time was 135 minutes. No transfusion was required nor had intraoperative complications occurred. Oral intake was initiated in postoperative day 2, and the patient was discharged postoperative day 6 without complications. Normal activities were recovered after 21 days. In a 3-month follow-up, there were no infectious complications, and good urinary drainage was observed. She was satisfied and adapted to the stoma. CONCLUSIONS: Video-assisted double-barreled wet colostomy is a feasible procedure. The same goals of the open procedure were achieved, offering the advantages of the laparoscopic approach.

RESUMO

OBJECTIVES: Describe and illustrate a new minimally invasive approach for the radical resection of inguinal lymph nodes. SURGICAL TECHNIQUE: From the experience acquired in 7 operated cases, the video endoscopic inguinal lymphadenectomy (VEIL) technique was standardized in the following surgical steps: 1) Positioning of the inferior member extended in abduction, 2) Introduction of 3 work ports distal to the femoral triangle, 3) Expansion of the working space with gas, 4) Retrograde separation of the skin flap with a harmonic scalpel, 5) Identification and dissection of the long saphenous vein until the oval fossa, 6) Identification of the femoral artery, 7) Distal ligature of the lymph node block at the femoral triangle vertex, 8) Liberation of the lymph node tissue up to the great vessels above the femoral floor, 9) Distal ligature of the long saphenous vein, 10) Control of the saphenofemoral junction, 11) Final liberation of the surgical specimen and endoscopic view showing that all the tissue of the region was resected, 12) Removal of the surgical specimen through the initial orifice, 13) Vacuum drainage and synthesis of the incisions. COMMENTS: The VEIL technique is feasible and allows the radical removal of inguinal lymph nodes in the same limits of conventional surgery dissection. The main anatomic repairs of open surgery can be identified by the endoscopic view, confirming the complete removal of the lymphatic tissue within the pre-established limits. Preliminary results suggest that this technique can potentially reduce surgical morbidity. Oncologic follow-up is yet premature to demonstrate equivalence on the oncologic point of view.

RESUMO

PURPOSE: To make an objective controlled comparison of pain tolerance in transrectal ultrasound-guided prostatic biopsy using intrarectal topic anesthesia, injectable periprostatic anesthesia, or low-dose intravenous sedation. MATERIALS AND METHODS: One hundred and sixty patients were randomized into 4 groups: group I, intrarectal application of 2% lidocaine gel; group II, periprostatic anesthesia; group III, intravenous injection of midazolam and meperidine; and group IV, control, patients to whom no sedation or analgesic was given. Pain was evaluated using an analogue pain scale graded from 0 to 5. Acceptance of a repetition biopsy, the side effects of the drugs and complications were also evaluated. RESULTS: 18/20 (90%) and 6/20 (30%) patients reported strong or unbearable pain in the group submitted to conventional biopsy and topical anesthesia (p = 0.23, chi-square = 1.41); whereas those submitted to periprostatic blockade and sedation, severe pain occurred in only 2/60 (3%) patients (p < 0.001, chi-square = 40.19) and 3/60 (5%) patients (p < 0.001, chi-square = 33.34). Acceptance of repetition of the biopsy was present in only 45% of the patients submitted to conventional biopsy, 60% of those that were given topical anesthesia (p = 0.52, chi-square = 0.4), compared to 100% of those submitted to periprostatic anesthesia (p < 0.01, chi-square = 15.17), and 95% of those who were sedated (p < 0.001, chi-square = 25.97%). CONCLUSIONS: Transrectal ultrasound-guided prostatic biopsy is an uncomfortable experience; however application of periprostatic blockade and intravenous analgesia are associated to higher tolerance of the exam and patient comfort. Low dose sedation by association of intravenous meperidine and midazolam is an emerging and safe outpatient option.

RESUMO

OBJECTIVES: Inguinal metastases are one of the major determinants of mortality in patients with penile cancer. In high risk patients, while prophylatic inguinal lymphadenectomy may offer survival advantages, it still carries a relatively high morbidity. We describe in this paper the first report of the Video Endoscopic Inguinal Lymphadenectomy (VEIL) in the clinical practice, a technique which aims at reducing the morbidity of the procedure without compromising the cancer control or reducing the template of the dissection. METHODS: A 40 year old male with a pT2 penile cancer underwent prophylatic bilateral inguinal lymphadenectomy 6 weeks after partial penectomy. We performed the VEIL technique at the right and a standard radical inguinal lymphadenectomy through an inguinal incision at the left (control). After developing a plane deep to Scarpa's fascia, locating 3 ports and infusing gas at 5-10 mmHg, a retrograde dissection with the same limits as the standard open surgery was performed. Intraoperative data, patology, post operatory evolution and oncological follow-up is described for both sides. RESULTS: Operative time was 130 min for the VEIL and 90 min for open surgery. Eight and 7 lymphnodes were retrieved at the VEIL side and open side, respectively, and none of then showed positivity at pathology. There were no complications in the limb which underwent the VEIL and there was skin necrosis in the side of the open surgery. After 25 months of follow up, no signs of disease progression were noted. Asked about how he felt about both surgeries, the patient chose the endoscopic approach. CONCLUSION: VEIL is feasible in clinical practice. New studies with a greater number of patients and long-term follow-up may confirm the oncological efficacy and possible lower morbidity of these new approach.

RESUMO

We present a case of retrocaval ureter featuring laparoscopic technique treatment using extraperitoneal access and extracorporeal suture of the ureteral stumps. Surgical time was 130 minutes, and the anastomosis was performed in 40 minutes. There were no intra- or postoperative complications, and the patient was discharged from hospital on the second postoperative day. The medium-term outcome featured similar results to pure laparoscopic technique. We conclude that this technical variation for treatment of retrocaval ureter makes the procedure easier and provides a drastic reduction in surgical time, without compromising the minimally invasive aspect of this kind of approach.

RESUMO

INTRODUCTION: We describe our experience with hand-assisted laparoscopy (HAL) as an option for the treatment of large renal specimens. MATERIALS AND METHODS: Between March 2000 and August 2004, 13 patients candidate to nephrectomies due to benign renal conditions with kidneys larger than 20 cm were included in a prospective protocol. Unilateral nephrectomy was performed in cases of hydronephrosis (6 patients) or giant pyonephrosis (4 patients). Bilateral nephrectomy was performed in 3 patients with adult polycystic kidney disease (APKD) with low back pain refractory to clinical treatment previous to kidney transplant. The technique included the introduction of 2 to 3 10 mm ports, manual incision to allow enough space for the surgeon's wrist without a commercial device to keep the pneumoperitoneum. The kidney was empty, preferably extracorporeally, enough to be removed through manual incision. We have assessed operative times, transfusions, complications, conversions, hospital stay and convalescence. RESULTS: The patients mean age (9 women and 4 men) was 58 years. Mean operating time was 120 +/- 10 min (hydronephrosis), 160 +/- 28 min (pyonephrosis) and 190 +/- 13 min (bilateral surgery for APKD). There was a need for a conversion in 1 case and another patient needed a transfusion due to a lesion in the renal vein; 2 patients had minor complications. CONCLUSIONS: HAL surgery is a minimally invasive alternative in the treatment of large renal specimens, with or without significant inflammation.

RESUMO

OBJECTIVE: To present results obtained with laparoscopic correction of incisional lumbar hernia in patients with minimum follow-up of 1 year. MATERIALS AND METHODS: We prospectively studied 7 patients diagnosed with incisional lumbar hernia after physical examination and computerized tomography. We used laparoscopic transperitoneal access through 3 ports. One polypropylene mesh was introduced in the abdominal cavity and fixed by titanium clamps to the margins of the hernia ring following release of the peritoneum. RESULTS: All cases were successfully completed with no conversion required. Mean surgical time was 120 minutes and discharge from hospital occurred between the 1st and the 2nd postoperative days. There were no intraoperative complications or hernia recurrence in any case. Postoperatively, we had 2 minor complications: one case of seroma that resolved spontaneously after 60 days and one patient presenting lumbar pain that persisted until the 3rd postoperative month. The return to usual activities occurred on average 3 weeks following intervention. Of the 7 patients, 6 were satisfied with the esthetical and functional effect produced by the procedure. CONCLUSIONS: The surgical correction of incisional lumbar hernia by laparoscopic access is an excellent option for a minimally invasive treatment, with adequate long-term results.

RESUMO

INTRODUCTION: The present study shows and discusses the preliminary experience of customized and staged approach in the minimally invasive treatment of inflammatory renal diseases, using either pure laparoscopic surgery or the hand-assisted technique. MATERIALS AND METHODS: We prospectively assessed 17 patients with inflammatory renal diseases operated by laparoscopic approach. Mean age was 41 years and the surgical indication was repeated pyelonephritis in 8 cases, pyonephrosis in 4 cases and renal exclusion due to staghorn stone in 5 cases. The staged laparoscopic approach was chosen based on kidney size and on the presence or not of tomographic findings showing significant perirenal infiltration. Thus, retroperitoneal access was chosen in cases where the kidney was smaller than 12 cm or in the absence of signs of significant perirenal infiltration on the computerized tomography. For the remainder, transperitoneal access was employed. RESULTS: Of the 17 patients, 11 underwent laparoscopic nephrectomy by retroperitoneal access, and all cases were successful. Mean surgical time was 160 minutes. In 6 cases where the nephrectomy was performed by laparoscopic transperitoneal access, the use of hand assistance was required. Four surgeries were successfully completed with mean time of 190 minutes and 2 were converted to open surgery with mean time of 220 minutes. CONCLUSION: The laparoscopic nephrectomy for inflammatory renal disease is feasible, but presents a high degree of complexity, requiring a customized approach. The use of hand assistance is an attractive option when the inflammatory process is intense, and can avoid conversions, maintaining the advantages of minimally invasive treatments.

RESUMO

OBJECTIVE: To describe surgical and functional results with extraperitoneal laparoscopic radical prostatectomy with duplication of the open technique, from the experience obtained in the treatment of 28 initial cases. MATERIALS AND METHODS: In a 36-month period, we prospectively analyzed 28 patients diagnosed with localized prostate cancer undergoing extraperitoneal laparoscopic radical prostatectomy. RESULTS: Mean surgical time was 280 min, with mean blood loss of 320 mL. As intraoperative complications, there were 2 rectal lesions repaired with laparoscopic suture in 2 planes. There was no conversion to open surgery. Median hospital stay was 3 days, with return to oral diet in the first post-operative day in patients. As post-operative complications, there were 3 cases of extraperitoneal urinary fistula. Two of these cases were resolved by maintaining a Foley catheter for 21 days, and the other one by late endoscopic reintervention for repositioning the catheter. Five out of 18 previously potent patients evolved with erectile dysfunction. The diagnosis of prostate cancer was confirmed in all patients, with focal positive margin occurring in 3 cases. During a mean follow-up of 18 months, 2 patients presented increased PSA, with no clinical evidence of disease. CONCLUSION: Laparoscopic radical prostatectomy is a laborious and difficult procedure, with a long learning curve. Extraperitoneal access is feasible, and it is possible to practically duplicate the principles of open surgery. The present technique can possibly offer advantages in terms of decreased blood loss, preservation of erectile function and prevention of positive margins.

RESUMO

OBJECTIVE: Evaluate objectively pain tolerance in transrectal ultrasound-guided prostate biopsy (TRUS) using local periprostatic anesthesia applied intrarectally, compared to the conventional method. MATERIAL AND METHODS: Forty patients were submitted to TRUS-guided prostate biopsy due to clinical suspicious of neoplasia. Patients were randomized in 2 groups: group-I, with 20 patients submitted to local anesthesia by 4 periprostatic injection of 2.5 mL 1% lidocaine, without epinephrine, TRUS-guided; and group-II, with 20 controls, with no sedatives or analgesia. After biopsy, patients were questioned about pain intensity during the procedure, using a grading scale from 0 to 5, correlating numbers, colors, and pain intensity. Pain related to probe manipulation or biopsy punctures, acceptance of an eventual re-biopsy, side effects of the drug used, and later complications of the procedure were also evaluated. RESULTS: Both groups were consistent comparing PSA levels, and prostate volume. As for pain intensity, 18/20 patients had severe or intolerable pain on the group submitted to conventional biopsy, while for those submitted to periprostatic blockage this event occurred in 3/20 patients (Chi(2 ) =22.50; p<0.01). The most important pain component was manipulation of the transrectal probe in 28% of patients, and puncture itself in 72%. Acceptance of re-biopsy as a pain evaluation criterion occurred in only 45% of patients submitted to conventional biopsy, compared to 100% of those submitted to periprostatic anesthesia (Chi (2)=15.17; p<0.01). CONCLUSION: TRUS-guided prostate biopsy is a traumatic and painful experience, but the periprostatic blockage use is clearly associated with more tolerance and patient comfort during the exam.

RESUMO

OBJECTIVE: To compare, prospectively, 4 different schemes of antibiotic prophylaxis previously to transrectal prostate biopsy. MATERIALS AND METHODS: 257 patients were randomized in 4 groups: Group I: single dose of ciprofloxacin 2 hours before the procedure; Group II: ciprofloxacin 3 days; Group III: chloramphenicol 3 days; and Group IV: norfloxacin 3 days. The complication rate was assessed in a blind way on the third and on the thirtieth days through a questionnaire. Groups were compared by the qui-square method and, in small samples, by the Fisher method, with statistical significance of 95%. RESULTS: Complications index throughout the sample differed between the 4 groups of patients under study, being 3.1% for group I, 2.1%for group II, 18.3% for group III and 10.5% for group IV. Schemes employing ciprofloxacin were statistically superior to those that used norfloxacin or chloramphenicol (p < 0.05). There was no difference between a single dose and 3 days of ciprofloxacin (p > 0.05). CONCLUSION: Schemes using ciprofloxacin presented better results in prophylaxis previously to prostate biopsy. We recommend using a single dose of ciprofloxacin due to its posologic ease and low cost, associated with a therapeutic response equivalent to 3-day regimens.

RESUMO

OBJECTIVE: No consensus has yet been established regarding the best minimally invasive access for radical ablation of renal tumors. Our objective was to prospectively compare the surgical results and oncologic management of two currently used endoscopic techniques. MATERIAL AND METHODS: Over a four-year period, 50 patients with renal tumors and clinical stage T1b-T2, smaller than 12 cm, underwent a radical nephrectomy at two reference institutions, 25 underwent retroperitoneoscopic radical nephrectomy (RRN) and 25 a hand-assisted laparoscopic radical nephrectomy (HALRN). Mean follow-up of both cohorts was 50 months. Operative parameters and oncological management were compared. RESULTS: The mean operative time was 180 min in RRN and 108 min in HALRN (p < 0.001). The time required to access the renal pedicle in RRN was 30 min. and in HALRN 40 min., Learning curve was shorter in HALRN than RRN. Mean blood loss was 100 mL in RRN and 242 mL in HALRN. Mean incision size for specimen retrieval in RRN was 6.5 cm and in HALRN 7.5 cm. One patient with intra operative occurrence of ascites and subsequent pathological stage pT2N0M0 grade 3 operated via HALRN, had neoplasic implants in the Hand-port incision 3 months after surgery followed by death 4 months after recurrence. One patient, with pathological stage pT3N0M0 grade 3 in RRN had metastasis after 36 months. CONCLUSION: Both, RRN and HALRN techniques are accepted minimally invasive options for endoscopic radical nephrectomy with equivalent long term oncological outcome in the treatment of renal tumors.

RESUMO

OBJECTIVE: The present study aims to report the preliminary experience with videolaparoscopic retroperitoneal lymphadenectomy in the treatment of patients with non-seminomatous testicular tumor. MATERIALS AND METHODS: Seven surgeries were performed in order to access retroperitoneal lymph nodes in patients with non-seminomatous testicular cancer. We performed the videolaparoscopic retroperitoneal lymphadenectomy (LRL) technique in 5 patients with stage I disease and laparoscopic resection of residual mass (LRRM), following chemotherapy (ChT), in 2 patients with stage II disease. Initial approach was obtained through 4 trocars, using an incision in supra-umbilical midline when manual assistance was required. Surgical time was analyzed, as well as blood loss, need for analgesic drugs postoperatively, hospital stay, complications, need for blood transfusion, histopathological data and tumor control in a mean follow-up of 18 months. RESULTS: Mean surgical time was 200 to 260 minutes in LRL and LRRM groups respectively, mean blood loss was 300 mL for the LRL group and 400 mL for the LRRM group, without need for transfusions. There was a lesion in the vena cava in the LRL group, which was managed with manual assistance and one conversion in the LRRM group, due to a 10-cm tumor mass that was adhered to the aorta. Mean hospital stay was 3 days, excluding the converted case, and the use of analgesic drugs was needed until the second postoperative day. Of the stage I patients, 2 had active disease in retroperitoneum, and underwent adjuvant ChT. The 2 residual masses were teratomas. There was no recurrence during the follow-up period. CONCLUSIONS: Videolaparoscopic retroperitoneal lymphadenectomy is a procedure with high technical complexity and a higher potential for conversion when performed following chemotherapy.

RESUMO

Laparoscopic surgery in urology is definitely incorporated to the techniques of minimally invasive treatment for urogenital diseases. Though the classic access to organs in the urinary tract is extraperitoneal, this access has not been prioritized when the videoendoscopic technique is used. In Brazil, few groups use this approach and little has been discussed about its true practical applicability. The authors intended to discuss the main technical aspects and criteria for indication, reported though the improvement achieved in a 5-year period with 150 operated cases. A review of the literature shows that the worldly acceptance of the extraperitoneal endoscopic approach is increasing. Nevertheless, there are no evidences that the extraperitoneal access is superior to the transperitoneal route. Thus, the choice depends basically on the surgeon's preference. Major advantages are the immediate access to the renal hilum and isolation of peritoneal structures. Employing this access is useful when one suspects that significant peritoneal adherences could prevent the surgical act or when one wishes to preserve the integrity of the peritoneal cavity.

RESUMO

INTRODUCTION: The laparoscopic radical prostatectomy is a continually developing technique. Transperitoneal access has been preferred by the majority of centers that employ this technique. Endoscopic extraperitoneal access is used by a few groups, nevertheless it is currently receiving a higher acceptance. In general, the antegrade technique is used, with dissection from the bladder neck to the prostate apex. The objective of the present paper is to describe the extraperitoneal technique with reproduction of the open surgery's surgical steps. SURGICAL TECHNIQUE: With this technique, the dissection of the prostate apex is performed and, following the section of the urethra while preserving the sphincteric apparatus, the Foley catheter is externally tied and internally recovered, which allows cranial traction, similarly to the way it is performed in conventional surgery. The retroprostatic space is posteriorly dissected and the seminal vesicles are identified by anterior and posterior approach, obtaining with this method an optimal exposure of the posterolateral pedicles and the prostate contour. The initial impression is that this technique does not present higher bleeding rate or difficulty level when compared with antegrade surgery. Potential advantages of this technique would be the greater familiarity with surgical steps, isolated extraperitoneal drainage of urine and secretions and a good definition of prostate limits and lateral pedicles, which are critical factors for preserving the neurovascular bundles and avoiding positive surgical margins. A higher number of cases and a long-term follow-up will demonstrate its actual value as a technical option for endoscopic access to the prostate.

RESUMO

INTRODUCTION: Surgery represents the main therapeutic modality for stress urinary incontinence. In incontinent patients with urethral hypermobility, the retropubic colposuspension by Burch technique is one of the surgeries that present better long-term results. Current trends towards performing minimally invasive techniques led proposing the Burch surgery through videolaparoscopy. The laparoscopic technique's long-term efficacy is a highly controversial issue. However, even if late results turn out to be satisfactory, the assumed advantages of laparoscopy (faster recovery, less pain, early return to daily activities, etc.) must be evident, in order to justify the use of this minimally invasive surgical access. MATERIALS AND METHODS: We reviewed our records and analyzed the medical charts of 26 female patients who underwent Burch surgery by open approach and 36 female patients by laparoscopic approach, between May 1999 and February 2001. The satisfaction level, surgical complication rates, surgery length, hospital stay and return to daily activities were analyzed. RESULTS: Mean age was 42 years, ranging from 27 to 68 years. Epidemiological data from both groups were not statistically different. Patients operated by laparoscopic route had a shorter hospital stay (p = 0.002) and a faster return to their daily activities (p < 0.001). However, there were no statistical differences in the following parameters: surgical time (p = 0.11), surgical complications (p = 0.98), patient satisfaction immediately (p = 0.77) and 90 days following surgery (p = 0.84), surgery acceptance (p = 0.85), indication of this surgery to a friend (p = 0.93) and score given to the procedure (p = 0.68). CONCLUSIONS: Even if the efficacy of both methods is similar, we did not observe significant advantages of laparoscopic surgery over open surgery, concerning the recovery in recent post-operative period.
