Radical hysterectomy: does the type of incision matter?

Pure versus hand-assisted retroperitoneoscopic live donor nephrectomy: a retrospective cohort study of 1508 transplants from two centers

BACKGROUND

Although minimally invasive procedures have been established as the standard for a donor nephrectomy, there are many different surgical techniques described in the literature. The aim of this study is to compare the outcomes of kidney transplant procedures using the pure retroperitoneoscopic donor nephrectomy (PRDN) and hand-assisted retroperitoneoscopic donor nephrectomy (HARDN) techniques.

METHODS

A retrospective study involving 1508 transplant procedures was conducted; 874 were PRDN procedures; and 634 were HARDN. We reviewed the outcomes of the PRDN and HARDN groups, which were performed at two different centers over an identical time period.

RESULTS

Donors in the PRDN group had a longer operation time (P < 0.0001), reduced estimated blood loss (P < 0.0001), less open conversion (P = 0.0002), lower postoperative serum C-reactive protein levels (P < 0.0001), and a shorter postoperative hospital stay (P < 0.0001) than the HARDN group. Recipients in the PRDN group had lower serum creatinine levels at postoperative day 1-6 and the decreased incidence of slow graft function (P = 0.0017) than the HARDN group. The HARDN procedure was an independent risk factor for the incidence of acute rejection (P = 0.0211) and graft loss (P = 0.0193).

CONCLUSIONS

Our study suggests that the PRDN procedure is less invasive for donors as it results in reduced blood loss, lower postoperative serum CRP levels, and a shorter postoperative stay than the HARDN procedure. Additionally, PRDN provides a better outcome for recipients as it lowers the incidence of acute rejection and improves graft survival compared to HARDN.

Incisional hernia, midline versus low transverse incision: what is the ideal incision for specimen extraction and hand-assisted laparoscopy?

BACKGROUND

Minimally invasive surgery is associated with smaller surgical incisions than those of traditional midline laparotomy. However, most colorectal resections and all hand-assisted procedures require an incision either for specimen retrieval or insertion of the hand-assist device. The ideal site of this incision has not been evaluated with respect to the incidence of incisional hernia. This study compares the rates of incisional hernia associated with a standard midline laparotomy, a midline incision of reduced length, and a Pfannenstiel incision.

METHODS

From March 2004 to July 2007, 512 consecutive patients were identified from a prospectively maintained database according to predefined inclusion and exclusion criteria. Patients were divided into three groups depending on the type of incision (open, midline, and Pfannenstiel). Demographic variables, rate of incisional hernia, and risk factors for hernia were compared among the groups.

RESULTS

There were 142, 231, and 139 patients in the open, midline, and Pfannenstiel groups, respectively. All three groups were comparable with respect to age, gender, steroid use, diabetes, number of patients with malignancy, and duration of follow-up. The Pfannenstiel group had a higher mean BMI (p = 0.015) and the open group had a higher rate of wound infection (28.2%) compared to the other groups. Incidence of incisional hernia was similar for the open and midline groups (19.7 and 16%, p = 0.36). At a mean follow-up of 17.5 months, not a single patient with a Pfannenstiel incision developed an incisional hernia (p < 0.001). BMI (p = 0.019), follow-up (p < 0.001), and Pfannenstiel incision (p < 0.001) were found to be predictors (protectors) of incisional hernia on multivariate analysis.

CONCLUSION

A Pfannenstiel incision is associated with the lowest rate of incisional hernia and should be the incision of choice for hand assistance and specimen extraction in minimally invasive colorectal resections wherever applicable.

Prechemotherapy laparoscopic nephrectomy for Wilms' tumor

Laparoscopic radical nephrectomy is emerging as the treatment of choice for localized renal malignancies in adults. Despite the widespread use of laparoscopic nephrectomy for benign renal disease in infants and children, the laparoscopic approach has not been employed for pediatric Wilms' tumor except following systemic chemotherapy. We report the results of laparoscopic radical nephrectomy for removal of unilateral Wilms' tumor prior to the administration of systemic chemotherapy in two patients.

Comparison of modified Cherney incision and vertical midline incision for management of early stage cervical cancer

OBJECTIVE

The aim of this study was to compare operative feasibility and surgical outcome of the modified Cherney incision and vertical midline incision in patients undergoing radical hysterectomy and pelvic lymphadenectomy.

METHODS

Between March 2005 and December 2007, retrospective data of 78 patients (n=17; modified Cherney incision, n=61; vertical midline incision) with early stage cervical cancer who received radical hysterectomy and pelvic lymphadenectomy were reviewed.

RESULTS

Baseline characteristics of patients who underwent modified Cherney incision and vertical midline incision were similar except for age (mean+/-SD: 32.3+/-3.4 yr vs. 52.5+/-8.4 yr, p<0.001). Patients who received modified Cherney incision had earlier initiation of soft diet (mean+/-SD: 46.5+/-19.5 hr vs. 56.4+/-25.4 hr, p<0.016) and shorter hospital stay compared to those who received vertical midline incision (mean+/-SD: 18.0+/-4.8 days vs. 21.7+/-3.7 days, p<0.042). There was no difference in the number of dissected pelvic lymph nodes, hemoglobin change, postoperative pain, postoperative ileus, Foley indwelling duration, and perioperative complications.

CONCLUSION

Excluding the selection bias for age, there was no significant difference of the clinical outcome between the modified Cherney incision group and the vertical midline incision group. Modified Cherney incision can be cosmetically performed in young age women obtaining equal number of lymph nodes without increased operative morbidity compared to vertical midline incision.

Feasibility of the Maylard transverse incision for ovarian cancer cytoreductive surgery

The vast majority of abdominal incisions used in gynecologic surgery are either transverse or vertical midline. The advantages of a vertical midline incision are considered to be rapid abdominal entry and increased exposure to the abdomen and pelvis. The advantages of transverse incisions are purported to be cosmesis, decreased postoperative pain, decreased hernia rate, decreased abdominal adhesions, and fewer postoperative pulmonary complications. The Maylard incision is a transverse incision that combines the advantages of a transverse incision with improved pelvic and abdominal exposure. We wanted to evaluate the feasibility of the Maylard incision to provide adequate abdominal and pelvic exposure in women with advanced ovarian cancer undergoing cytoreductive surgery and to evaluate the extent of anterior abdominal wall adhesions at secondary cytoreductive surgery. In our experience, it appears that the Maylard incision provides adequate exposure to perform ovarian cytoreductive surgery. It appears that there are minimal anterior abdominal adhesions after cytoreductive surgery through a Maylard incision.

Comparison of midline and Pfannenstiel incision for radical hysterectomy with pelvic and paraaortic lymphadenectomy in cervical carcinoma

AIM

To compare Pfannenstiel and midline incisions with respect to efficacy and early postoperative surgical site complications in patients with early stage cervical carcinoma.

METHODS

Patients with cervical carcinoma who underwent radical hysterectomy during 1995-2004 are retrospectively reviewed. There were 40 patients in the Pfannenstiel group and 71 patients in the midline group. Patients' age, type of incision, operative time, hospitalization length, postoperative surgical site complications, pre and postoperative Hb levels, number of extracted pelvic and paraaortic lymph nodes were the variables collected from the patients' files and oncology follow-up forms.

RESULTS

Mean age (53.5+/-6.96 vs 55.9+/-10.5, P=0.2) and preoperative Hb levels of patients (12.52+/-1.48 vs 12.94+/-1.34, P=0.17) were not statistically different in midline and Pfannenstiel groups, respectively. Operative time (141.8+/-36 vs 135.8+/-31 min), number of extracted lymph nodes in pelvic (23.05+/-9.7 vs 23.5+/-8.07) and paraaortic areas (3.17+/-1.68 vs 2.66+/-1.15) were not significantly different among the midline and Pfannenstiel groups, respectively (P>0.05). Although postoperative incisional complications were more common in the midline group, this difference did not reach a significant level (11.3% vs 7.5%, P=0.52). Duration of hospitalization was not significantly different between the midline and Pfannenstiel groups, respectively (6.3+/-2.69 vs 6.2+/-2.72 days, P=0.21). Multivariate analysis revealed postoperative Hb levels to be significantly different among the groups (P=0.017, OR=1.59, 95% CI: 1.08-2.35).

CONCLUSION

Pfannenstiel incision can be used for radical hysterectomy with pelvic and paraaortic lymphadenectomy in selected patients with cervical carcinoma, without any negative influence on optimal resectability of tumor and surgical morbidity.

Nerve-sparing class III radical hysterectomy: a modified technique to spare the pelvic autonomic nerves without compromising radicality

The objectives were to describe our nerve-sparing class III radical hysterectomy technique and assess the feasibility and safety of the procedure as well as its impact on voiding function. From January to August 2005, 21 consecutive patients with FIGO stage IB-IIA cervical cancer and 1 patient with clinical stage II endometrial cancer underwent nerve-sparing radical hysterectomy with systematic pelvic lymphadenectomy. The transurethral catheter was removed on the seventh postoperative day. Then intermittent self-catheterization was performed and post-void residual urine volume (PVR) was recorded. The nerve-sparing procedure was completed successfully and safely in all of the patients. Eight (36%) and 6 (27%) patients had the PVR of < 100 ml and < 50 ml respectively at the initial removal of the catheter. On the fourteenth day, 82% and 77% of the patients had the PVR of < 100 ml and < 50 ml, respectively. The mean duration before the PVR became < 50 ml was 11.27 (5-26) days. In conclusion, the technique described in this preliminary study appears safe, adequate, and feasible in our population with satisfactory recovery of voiding function. A larger comparative study is needed on long-term urinary, bowel, and sexual function as well as recurrence and survival.

Pfannenstiel versus Vertical Laparotomy in Patients Undergoing Radical Retropubic Prostatectomy with Spinal Anesthesia: Results of a Prospective, Randomized Trial

OBJECTIVE

To evaluate the impact of a standard vertical laparotomy versus a Pfannenstiel transverse laparotomy on intra-, peri-operative, and 6-month follow-up outcome in patients undergoing radical retropubic prostatectomy with pelvic lymphadenectomy with spinal anesthesia.

METHODS

Between January 2003 and June 2003, 69 age-matched consecutive patients with clinically localized prostate cancer underwent radical retropubic prostatectomy with pelvic lymphadenectomy with spinal anesthesia and were randomized into Group 1 (vertical laparotomy: 35 patients) and Group 2 (Pfannenstiel laparotomy: 34 patients). An extensive analysis of the critical intra-, peri-operative, and 6-month follow-up clinical parameters was performed.

RESULTS

Both the hemodynamics and the biochemical balance were not significantly different between the two groups. Overall blood loss (p = 0.78), autologous (p = 0.88) and homologous (p = 0.36) blood transfusions were similar regardless of the type of laparotomy. Surgical time was not significantly (p = 0.27) different between the two groups. Similarly, the two forms of laparotomy did not differ regarding the length of the surgical incision (p = 0.21), as measured at the end of the procedure. Post-operative oxygen saturation percentage by pulse oximetry, as well as post-op sedation score, were not significantly different (p = 0.06 and p = 0.97, respectively). Waiting time in the post-operative holding area (p = 0.15), and pain score in the post-operative holding area (p = 0.9) as well as on post-operative day 1 (p = 0.1) were not significantly different between the two groups. The rate of first flatus passage and of unassisted ambulation were similar regardless of the type of laparotomy during post-operative day day 1. The two types of incision made it possible to remove a similar (p = 0.34) number of pelvic lymph nodes and were associated to a similar rate of positive surgical margins among pT2 patients. At the 6-month follow-up the occurrence of a pelvic lymphocele and of deep venous thrombosis was similar in the two groups (p = 0.6 and p = 0.16, respectively). Complete urinary continence and spontaneous erectile function recovery was reported in a similar number of patients regardless of the type of surgical incision (p = 0.59 and p = 0.40, respectively).

CONCLUSIONS

These results suggest that a Pfannenstiel transverse suprapubic laparotomy does not result in a significantly different outcome from a standard vertical laparotomy in patients undergoing a radical retropubic prostatectomy with pelvic lymphadenectomy with L2-L3 spinal anesthesia for clinically localized prostate cancer.

Minilaparotomy for type II and III radical hysterectomy: technique, feasibility, and complications

The objective was to assess the feasibility, the operative and postoperative outcome, and complications in the use of minilaparotomy for type II and III radical hysterectomy (RH) and pelvic lymphadenectomy (PLN) in early-stage cervical/endometrial cancer. A pilot study on 91 consecutive patients submitted to type II and III RH and PLN for early-stage cervical/endometrial cancer was performed between March 2002 and May 2003 in the Division of Gynecologic Oncology (UCSC, Rome). Thirty-two of 91 cases (35.2%) were eligible for minilaparotomy. The mean operative time was 156.7 min, whereas the mean intraoperative estimate of blood loss was 303.7 ml. A mean number of 32.7 pelvic lymph nodes and 6.2 common iliac nodes were removed. Ileus and removal of bladder catheter were on mean postoperative day 2.4 and 3.4, respectively. The mean number of postoperative days spent in the hospital was 3.7. Intra- and postoperative parameters were compared to laparotomy controls and literature data on laparoscopy and Pfannenstiel incision, showing substantially comparable results. Minilaparotomy is acceptable for selected patients undergoing radical abdominal hysterectomy (RAH) and PLN and does not compromise the adequacy of the procedure. It can be considered as an alternative to the classic midline vertical incision or even to the Pfannenstiel incisions and laparoscopy.

Cancer of the endometrium: current aspects of diagnostics and treatment

Background

Endometrial cancer represents a tumor entity with a great variation in its incidence throughout the world (range 1 to 25). This suggests enormous possibilities of cancer prevention due to the fact that the incidence is very much endocrine-related, chiefly with obesity, and thus most frequent in the developed world. As far as treatment is concerned, it is generally accepted that surgery represents the first choice of treatment. However, several recommendations seem reasonable especially with lymphadenectomy, even though they are not based on evidence. All high-risk cases are generally recommended for radiotherapy.

Methods

A literature search of the Medline was carried out for all articles on endometrial carcinoma related to diagnosis and treatment. The articles were systematically reviewed and were categorized into incidence, etiology, precancerosis, early diagnosis, classification, staging, prevention, and treatment. The article is organized into several similar subheadings.

Conclusions

In spite of the overall good prognosis during the early stages of the disease, the survival is poor in advanced stages or recurrences. Diagnostic measures are very well able to detect asymptomatic recurrences. These only seem justified if patients' chances are likely to improve, otherwise such measures increases costs as well as decrease the patients' quality of life. To date neither current nor improved concepts of endocrine treatment or chemotherapy have been able to substantially increase patients' chances of survival. Therefore, newer concepts into the use of antibodies e.g. trastuzumab in HER2-overexpressing tumors and the newer endocrine compounds will need to be investigated. Furthermore, it would seem highly desirable if future studies were to identify valid criteria for an individualized management, thereby maximizing the benefits and minimizing the risks.

Adequate staging for uterine cancer can be performed through Pfannenstiel incisions

OBJECTIVE

To determine if the type of operative incision influences the adequacy of surgical staging in patients with uterine cancer.

METHODS

All patients with uterine cancer referred to the Swedish Medical Center Cancer Institute for adjuvant radiotherapy between June 1, 1989, and June 1, 1999, who underwent comprehensive surgical staging and for whom complete records could be obtained were eligible. Data on type of incision, weight, medical comorbidities, histology, total number and distribution of lymph nodes (LN), estimated blood loss, complications, and length of stay were abstracted retrospectively. Statistical analysis with two-tailed Student t test, chi(2), Fisher's exact, and Kaplan-Meier survival curves were performed.

RESULTS

Five hundred four women with uterine cancers were referred to the Cancer Institute with 332 meeting inclusion criteria. A vertical midline incision (ML) was used in 236 (72%) while 96 (28%) received a Pfannenstiel incision (PI). No panniculectomies were performed. There were no statistically significant differences in age, weight, stage, histology, comorbidities, or estimated blood loss between the ML and PI groups. ML was associated with significantly more intraoperative and postoperative complications (34 vs. 7; P = 0.003). When compared to ML a greater number of total LN (21.0 vs. 16.8; P = 0.001) and a comparable number of pelvic LN (13.7 vs. 12.2; P = 0.14) were procured through a PI. More patients with a ML (72% vs. 63%; P = 0.13) had para-aortic lymph nodes (PALN) dissected; however, when obtained equivalent numbers of nodes were removed (3.52 vs. 4.36; P = 0.14). Overall, the median length of stay was statistically shorter for those patients operated on via a PI (4 vs. 3 days; P = 0.007). The projected 5-year disease-free (83% vs. 85%) and disease-specific (87% vs. 85%) survival was unaffected by incision. In the heaviest quartile of patients (>180 lb), a statistically greater number of total LN (23.3 vs. 16.5; P = 0.005) and pelvic LN (16.7 vs. 11.5; P = 0.05) were obtained with a PI. Again, PALN were sampled more frequently (67% vs. 56%; P = 0.45) in patients with a ML, but the mean LN yield was no different (3.91 vs. 5.20; P = 0.37). Likewise, in this heaviest quartile, there were no statically significant differences in operative complications (7 vs. 1; P = 0.43) with either incision.

CONCLUSIONS

Comprehensive surgical staging for uterine cancers can be adequately performed through a PI without greater morbidity or mortality. By using this surgical approach, patients with uterine cancer can benefit from the inherent benefits previously described for PI. Appropriate patient selection, however, is necessary.

Minilaparotomy in early stage endometrial cancer: an alternative to standard and laparoscopic treatment

OBJECTIVE

Our objective was to determine whether minilaparotomy could be a safe and feasible approach for the surgical treatment of early endometrial cancer patients and whether it could be considered a valid alternative to the laparoscopic treatment.

METHODS

A pilot study of 50 consecutive patients with FIGO stage I-IV endometrial cancer undergoing surgery at our Department was performed between May and December 2001. All patients were evaluated for a minimal transabdominal approach. Exclusion criteria were considered: special histotype, poorly differentiated tumors, clinical stage >/=Ic, Ca125 >35 U/ml, BMI >30, lymph nodal involvement assessed by MRI, and severe cardiopulmonary disease precluding steep Trendelenburg position.

RESULTS

Twenty-six (52%) cases were considered eligible for minilaparotomy. The mean age was 55.4 years and the mean BMI was 24.1. All patients underwent TAH, BSO, pelvic lymphadenectomy +/- omental or peritoneal biopsy. A mean number of 28 pelvic lymph nodes were removed. The mean operative time was 113.0 min and the mean intraoperative blood loss was 220.0 ml. There was 1 severe operative hemorrhage and 1 patient needed postoperative blood transfusion. No immediate complications of wound infection or separation occurred. The mean hospital stay was 3.4 days. Intra- and postoperative parameters were compared to laparotomy controls and literature data on laparoscopy, showing substantially comparable results.

CONCLUSION

Minilaparotomy is a feasible alternative to the standard treatment in endometrial cancer patients. It offers the patient a cost-effective procedure that avoids many of the potential complications of standard therapy, prevents long hospital recovery periods, and accomplishes all of the important goals of standard recommendations.

Radical abdominal hysterectomy

Radical abdominal hysterectomy and pelvic lymphadenectomy remain the gold standard procedures for the treatment of early cervical cancer. Over the years, the establishment of formal gynecologic oncology training programs, general medical advancements, and new surgical techniques have resulted in a satisfactory tumor resection, with improved overall therapeutic index and reliable cure rates. The role of neoadjuvant and adjuvant therapy continues to be defined as the results from randomized trials emerge.

A Retrospective Analysis of Radical Hysterectomies Done for Cervical Cancer: Is There a Role for the Pfannenstiel Incision?

OBJECTIVE

The goal of this work was to review patients with early-stage cervical cancer undergoing radical hysterectomy, comparing Pfannenstiel and vertical midline incisions for surgical feasibility, complications, and length of stay.

METHODS

Patients were identified by searching our institutional database. Data were collected from review of each patient's medical record, including demographics, cancer stage, histology, procedural information, length of stay, and complications. Associations between variables were studied using chi(2) and two-tailed t tests. Multivariate analysis was performed using logistic regression.

RESULTS

Between March 1996 and June 2000, 113 patients from the University and Presbyterian Hospitals, Oklahoma City, Oklahoma, underwent radical hysterectomy and pelvic and paraortic lymph node dissection with records available for review. Group 1 consisted of 40 patients who had vertical incisions and group 2 consisted of 73 patients who had Pfannenstiel incisions. There was no difference in race, number of previous abdominal surgeries, distribution of stage, histology, percentage of type III hysterectomies, estimated blood loss, nodal counts, pathologic margin positivity, and postoperative complications among the two groups. Group 2 were younger (41.6 vs 46.5, P = 0.02) and had a lower average QI than group 1 (24.9 vs 28.9, P = 0.001). Group 2 also had a shorter average hospital stay (4.6 days vs 5.8 days, P = 0.04) and shorter operative time (215 min vs 273 min, P = 0.09). Multivariate analysis resulted in Pfannenstiel incisions (P = 0.002), younger age (P = 0.004), and smaller body mass index (P = 0.01) being significant predictors of length of stay.

CONCLUSIONS

Pfannenstiel incisions are feasible without increased morbidity and equal nodal retrieval as compared with vertical midline incisions in patients with early-stage cervical cancer. Pfannenstiel incisions may offer an advantage besides cosmesis in the form of shorter operating room time and earlier discharge from the hospital.

Subspecialty training: does it affect the outcome of women treated for a gynecologic malignancy?

A review of available direct and indirect scientific reports strongly suggests that subspecialty training increases the likelihood that the appropriate surgical procedure will be completed in women operated on for gynecologic cancer. It is likely that specialty care lessens the costs associated with diagnosis, treatment and surveillance, and frequently improves survival.

Laparoscopically assisted ileocolectomy for Crohn's disease through a pfannenstiel incision

Recently, laparoscopically assisted bowel resections have been shown to be less morbid than the traditional laparotomy, especially for benign conditions such as Crohn's disease. While reports describing laparoscopically assisted bowel resections use a small midline or right transverse incision, we describe a novel laparoscopically assisted approach employing a Pfannenstiel incision for Crohn's patients. We attempted the Pfannenstiel incision since it is well known to be associated with less postoperative pain, decreased ileus and hospital stay, and low rates of wound infection and incisional hernia, compared with midline or right transverse incisions. Furthermore, we found that the Pfannenstiel incision offers additional advantages that may be uniquely suited for Crohn's patients. First, the cosmetic position of the incision is particularly attractive to the young population affected by Crohn's. Second, the Pfannenstiel incision preserves fresh tissue in the midline, right, and left lower quadrants in the event that reoperation or stoma placement are required in the future owing to recurrent disease. We describe our technique in 10 consecutive patients undergoing ileocolectomy for Crohn's disease. Our patients experienced minimal morbidity and were pleased with the cosmetic results of their incisions.

Laparoscopic radical hysterectomy with pelvic lymphadenectomy for early, invasive cervical carcinoma

STUDY OBJECTIVE

To demonstrate the feasibility and evaluate the efficacy of laparoscopic radical hysterectomy with pelvic lymphadenectomy for early, invasive cervical cancer.

DESIGN

Prospective study (Canadian Task Force classification II-2).

SETTING

University-affiliated hospital.

PATIENTS

Eighteen women (age range 29-70 yrs) with early, invasive cervical cancer.

INTERVENTION

Laparoscopic radical hysterectomy with pelvic lymphadenectomy.

MEASUREMENTS AND MAIN RESULTS

Diagnoses were squamous cell carcinoma in15 patients and adenocarcinoma of the cervix in 3; these were graded microcarcinoma in 6 and stage Ib (<4 cm) in 12. Mean operating time was approximately 363 +/- 65 minutes (range 240-475 min). Blood loss averaged 619 +/- 297 ml (range 250-1000 ml). The average number of pelvic lymph nodes obtained was 22.0 +/- 8.5 (range 14-40). Specimen weight averaged 117 +/- 67 g (range 60-340 g). Surgical margins were clear in all patients. No procedure was converted to laparotomy. There were no major intraoperative complications involving injury to main blood vessels, nerves, bowel, bladder, or ureters.

CONCLUSION

In our experience, laparoscopic radical hysterectomy with pelvic lymphadenectomy is acceptable in accordance with the standards of gynecologic oncology. Despite the longer operating time than traditional abdominal radical hysterectomy, all patients recovered as quickly as they would after laparoscopic-assisted vaginal hysterectomy. We believe that this procedure could be an alternative to abdominal radical hysterectomy for selected women, especially those who have stage Ib1 cervical cancer.
