Laparoscopic cytoreduction for primary advanced ovarian cancer

Laparoscopic-assisted cytoreduction for primary advanced ovarian cancer was found to be a feasible intervention technique with minimal morbidity.

Introduction:

We evaluated the feasibility of laparoscopic cytoreduction for primary advanced ovarian cancer.

Methods:

All patients with presumed stage 3/4 primary ovarian cancer underwent attempted laparoscopic cytoreduction. All patients had CT evidence of omental metastasis and ascites. A 5-port (5-mm) transperitoneal approach was used. A bilateral salpingo-oophorectomy, supracervical hysterectomy, and omentectomy were performed with PlasmaKinetic (PK) cutting forceps. A laparoscopic 5-mm Argon-Beam Coagulator was used to coagulate tumor in the pelvis, abdominal peritoneum, intestinal mesentery, and diaphragm.

Results:

Nine of 11 cases (82%) were successfully de-bulked laparoscopically without conversion to laparotomy. Median operative time was 2.5 hours, and median blood loss was 275 mL. All tumors were debulked to <2 cm and 45% had no residual disease. Stages were 1–3B, 7–3C, and 1–4. Median length of stay was one day. Median VAS pain score was 4 (discomforting). Two of 11 patients (18%) had postoperative complications.

Conclusion:

Laparoscopic cytoreduction was successful and resulted in minimal morbidity. Because of our small sample size, additional studies are needed.

Transvaginal application of a laparoscopic bipolar cutting forceps to assist vaginal hysterectomy in extremely obese endometrial cancer patients

INTRODUCTION

The purpose of this report is to evaluate our experience with transvaginal application of a laparoscopic bipolar cutting forceps to assist vaginal hysterectomy in extremely obese women with endometrial cancer in whom obesity precluded LAVH/BSO and lymphadenectomy and vaginal obesity limited visualization and exposure.

MATERIALS AND METHODS

We performed a retrospective review and identified 6 consecutive cases. No cases were excluded. A laparoscopic 33-cm Plasma Kinctic (PK) cutting forceps with a 5-mm diameter was applied transvaginally to coagulate and cut the uterosacral and cardinal ligaments, uterine vasculature, and ovarian ligaments. The uterus was delivered vaginally. Staging lymphadenectomy was not performed.

RESULTS

Median age was 51 years, median weight was 405 lbs, and median BMI was 66 kg/m². Five of 6 cases were successfully performed vaginally (83%). Median operative time was 1 hour 10 minutes, median blood loss was 500 mL, and pain was only discomforting. All patients were discharged the day after surgery. There were no complications. At median follow-up of 1 year, all patients were alive with no evidence of disease.

CONCLUSION

It is our opinion that the transvaginal application of a laparoscopic bipolar cutting forceps can successfully assist vaginal hysterectomy in extremely obese endometrial cancer patients who cannot tolerate LAVH/BSO and lymphadenectomy and vaginal obesity limits visualization and exposure.

A preliminary study of transcranial direct current stimulation for the treatment of refractory chronic pelvic pain

BACKGROUND

The modulatory effects of transcranial direct current stimulation (tDCS) appear beneficial for different chronic pain syndromes; however, it is unclear whether this method can be used to treat refractory chronic pelvic pain.

OBJECTIVE

The objective of this preliminary study was to determine the efficacy and safety of tDCS for the management of refractory chronic pelvic pain.

METHODS

Seven patients with chronic pelvic pain having failed standard medical or surgical therapy underwent a crossover, double-blind sham controlled tDCS treatment protocol consisting of 1 mA applied for 20 minutes on two consecutive days with 2 weeks of follow-up symptom recording. Symptoms were recorded using multiple scoring systems, including visual analog scales for different pains, as well as organ-specific symptom scales. Comparison between active and sham treatment was performed by using paired t tests.

RESULTS

Overall and pelvic pain scores were significantly lower after active compared with sham treatment, as were disability and traumatic stress scores. No patient discontinued the study because of side effects, which were infrequent.

CONCLUSIONS

Active tDCS treatment induces a modest pain reduction in refractory chronic pelvic pain patients as compared with sham tDCS treatment. These results can guide the design and implementation of further studies investigating this method of neuromodulation for the treatment of refractory chronic pelvic pain.

A method for the consistent creation and quantitative testing of postoperative pelvic adhesions in a porcine model

INTRODUCTION

The assessment of methods for the prevention of postoperative pelvic adhesions is hampered by the lack of a quantifiable adhesion measurement technique. Currently available methods for adhesion model assessment rely on qualitative grading scales; a quantitative method would have many attendant benefits, including standardized reporting.

METHODS

A technique was developed to generate consistent and significant adhesions in a swine model that are suitable for quantitative assessment using a Material Testing System (MTS) machine platform. In this method, the uterine horns are cannulated and then attached to the pelvic sidewall using loose silk sutures. The underlying sidewall and adjacent uterine serosa are injured with electrocautery. Following a two-week survival the entire complex of uterine horn and sidewall are excised en bloc and prepared for MTS testing.

RESULTS

Extrication of the adhesion, as measured by the MTS platform, generates a quantitative assessment of adhesion strength that can be scaled and analyzed to produce several continuous variable descriptions.

DISCUSSION

This technique represents a novel quantitative method for adhesion assessment in an animal model. This quantitative technique may then be applied to accurately assess a range of adhesion prevention techniques, producing results which can be standardized for comparison.

Robotic radical hysterectomy

Robotic radical hysterectomy is increasingly being utilized in the treatment of cervical cancer and initial studies are promising. Compared to open radical hysterectomy, robotic radical hysterectomy is expected to result in decreased pain, infection, length of stay, and adhesions and quicker return to activity. Prospective randomized controlled trials are needed to compare robotic, laparoscopic and open radical hysterectomy for the treatment of cervical cancer.

Laparoscopic-assisted vaginal hysterectomy for uteri weighing 1000 grams or more

INTRODUCTION

Prospective randomized trials have proven the benefits of laparoscopic-assisted vaginal hysterectomy (LAVH) compared with abdominal hysterectomy. The purpose of this study was to evaluate the safety and efficacy of LAVH performed for uteri weighing > or =1000 grams.

METHODS

Fifteen patients underwent attempted LAVH for uteri >1000g. Median age was 45 years old (range, 31 to 57), and median weight was 170 pounds (range, 130 to 236); 64% had medical comorbidities, and 43% had prior pelvic surgery. Five ports (5 mm) were used to allow maximum uterine manipulation. Uterine vessels were doubly coagulated.

RESULTS

Fourteen of 15 cases (93%) were successfully completed laparoscopically. Median uterine weight was 1090 grams (range, 1000 to 1650). Median operative time was 3.5 hours (range, 2 to 4.6), and median blood loss was 400 mL (range, 100 to 1200). All patients were discharged on postoperative day one, and no patients developed a postoperative complication.

CONCLUSION

We believe that LAVH is a safe and effective approach for uteri larger than 1000 g. It is our opinion that 3 surgical techniques are required; maximum Trendelenburg position, adequate number of ports, and double coagulations of the uterine vessels.

Robotic radical hysterectomy

OBJECTIVE

Advanced laparoscopic procedures are increasing being used in gynecologic surgery. The da Vinci robotic system (Intuitive Surgical Corporation, Sunnyvale, CA) can further augment laparoscopic surgery. We describe our initial experience using the da Vinci robotic system to perform radical hysterectomy.

STUDY DESIGN

Twenty consecutive patients with primary stage IB-IIA cervical carcinoma underwent class 3 radical hysterectomy with the use of the da Vinci robotic system. Median age was 44 years, median weight was 69.9 kg, 65% of patients had medical comorbidity, and 40% had prior abdominal surgery.

RESULTS

All 20 patients successfully underwent robotic radical hysterectomy. Median operative time was 6.5 hours (3.5-8.5 hours) and median blood loss was 300 mL. All patients were discharged on the first day after surgery. At median follow-up of 2 years (0.6-3 years), 90% of patients are alive and disease free.

CONCLUSION

We report the first series of robotic radical hysterectomy for early stage cervical cancer. All cases were successfully performed robotically with minimal complications and all patients were discharged on postoperative day 1.

Phase I/II prospective trial of autologous platelet tissue graft in gynecologic surgery

STUDY OBJECTIVE

To perform the original phase I/II trial of autologous platelet tissue graft in gynecologic surgery to evaluate toxicity and efficacy on decreasing pain.

DESIGN

Prospective nonrandomized trial (Canadian Task Force classification II-A).

SETTING

Teaching hospital.

PATIENTS

Fifty-five consecutive patients undergoing major gynecologic surgery were entered into this prospective phase I/II trial and were matched with 55 patients from the previous 6 months.

INTERVENTION

After anesthesia was induced, peripheral venous blood (55 mL) was obtained from the patient producing, autologous platelet tissue graft (20 mL). At completion of surgery, autologous platelet tissue graft was directly applied to the surgical site.

MEASUREMENTS AND MAIN RESULTS

Median pain on the day of surgery was 2.7 (mild) in the autologous platelet tissue graft group vs 6.7 (severe) in the control group, p <.001. Likewise, pain on postoperative day 1 was 2.1 (mild) in the autologous platelet tissue graft group vs 5.5 (moderate) in the control group, p < or =.001. Median of morphine per hospital stay for the autologous platelet tissue graft group was 17 mg (range 1-98 mg) vs 26 mg (range 3-90 mg) in the control group, which was statistically significant at p = .02. There were no adverse effects associated with autologous platelet tissue graft.

CONCLUSIONS

In the original phase I/II prospective trial of autologous platelet tissue graft in gynecologic surgery, there were no apparent adverse effects, and pain was significantly reduced.

Findings from a 10-year follow-up of bone mineral density in competitive perimenopausal runners

OBJECTIVE

To evaluate bone mineral density (BMD) in perimenopausal competitive runners with long-term follow-up.

STUDY DESIGN

Fifteen master female runners between 40 and 50 years old who ran at least 20 miles per week were evaluated. BMD was measured by dual-energy x-ray absorptiometry (DEXA) at baseline and at the 10-year follow-up.

RESULTS

The median age was 46 and median miles run per week, 25. At baseline, after a median of 11 years of competitive running, hip BMD was above peak bone mass (T-score = 0.8) and that of age-matched controls (Z-score = 1.6), while lumbar spine BMD was below peak bone mass (T-score = -0.8) and equal to that of age-matched controls (Z-score = -0.1). At the 10-year follow-up, hip BMD fell below peak bone mass (T-score = -0.2, p = 0.0004) but was still above that of age-matched controls (Z-score = 0.5, p = 0.002), while there was little change in lumbar spine BMD.

CONCLUSION

Competitive running prior to the perimenopausal period seems to be associated with improved hip BMD. However, continued competitive running during the perimenopausal period is not associated with prevention of a perimenopausal hip BMD decline. In contrast, competitive running had little effect on peri-menopausal lumbar spine BMD.

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.

Cost-effectiveness analysis of the treatment of large leiomyomas: laparoscopic assisted vaginal hysterectomy versus abdominal hysterectomy

OBJECTIVE

The purpose of this study was to perform a cost-effectiveness analysis comparing the treatment of large leiomyomas by laparoscopic assisted vaginal hysterectomy (LAVH) versus abdominal hysterectomy (AH).

STUDY DESIGN

Twenty consecutive LAVH were compared to 20 consecutive AH for leiomyoma > or = 250 g. Hospital costs were obtained through Healthcare cost accounting system. The 6 principles of cost-effectiveness analysis were used.

RESULTS

The groups were similar in respect to age, weight, race, medical comorbidities, blood loss, and operative time. Median uterine weight (513 g) was approximately 20% > for LAVH. Length of stay and pain was significantly less for LAVH. Total hospital cost for AH was approximately 12% less expensive ($4394 vs $5023, P = .18).

CONCLUSION

Because of multiple benefits of LAVH versus AH and no significant difference in cost, we believe LAVH is an acceptable treatment for large leiomyoma.

Postoperative femoral motor neuropathy: diagnosis and treatment without neurologic consultation or testing

OBJECTIVE

To review the diagnosis and treatment of postoperative femoral motor neuropathy without neurologic consultation or testing.

STUDY DESIGN

A retrospective review of 6 consecutive patients with postoperative femoral motor neuropathy following gynecologic surgery. Diagnosis was made on clinical evaluation: history of falling during postoperative ambulation, quadriceps weakness, straight leg raise weakness, diminished knee jerk response, and no evidence of psoas hematoma or abscess. Neurologic consultation, electromyography, nerve conduction study and radiologic imaging, such as computed tomography, were not obtained. Instead, a physical therapy consultation was obtained for a knee orthotic and rehabilitation.

RESULTS

Four postoperative femoral motor neuropathies developed following 3,014 cases of major gynecologic surgery (0.1%). Two additional cases were seen in consultation. The median age was 57 years. All patients fell while attempting ambulation on postoperative day 1. Recovery occurred at a median of 3 months (1-4). At a median follow-up of 4 years, no patient had developed additional neurologic sequelae. A history of prior postoperative femoral motor neuropathy was noted in 2 of 6 patients (33%).

CONCLUSION

This was the first study of diagnosis and treatment of postoperative femoral motor neuropathy following gynecologic surgery without neurologic consultation or testing. Because of the significant expense of neurologic consultation and testing, patients with postoperative femoral motor neuropathy can have the condition diagnosed by the gynecologist and be referred directly to physical therapy without adversely affecting outcome. This also was the first study to elicit a prior history offemoral neuropathy in 33% of patients. Thus, a prior history may be a risk factor for recurrence.

A laparoscopic simulator tool for objective measurement of residents' laparoscopic ability

OBJECTIVE

We sought to develop an objective measurement of residents' laparoscopic ability by using a laparoscopic simulator assessment tool.

METHODS

An inexpensive laparoscopic simulator was developed. Three laparoscopic assessment procedures were created: 1) bead/pom-pom drop, 2) checkerboard drill, and 3) bead manipulation. Two minimally invasive surgeons and 8 PGY 3/4 and 15 PGY 1 residents were timed performing the 3 procedures. Ten of the PGY 1 residents were retested at the end of their PGY 1 year.

RESULTS

The minimally invasive surgeons completed the laparoscopic drills in approximately half the time of the PGY 3/4 (P=0.02), and PGY 3/4 were 60% faster than PGY 1 (P=0.01). PGY 1 completed the drills in half the time at the end of the PGY 1 year (P=0.005). As an objective measurement of residents' laparoscopic surgery competency, by the completion of the academic year, all PGY 1 residents must be able to complete the drills as fast as or faster than the original PGY 3/4 times.

CONCLUSION

We developed an inexpensive, objective, simple laparoscopic simulator assessment tool for measurement of residents' laparoscopic ability.

A laparoscopic bipolar cutting forceps can assist in a case of difficult vaginal hysterectomy

A vaginal approach to hysterectomy can become challenging when visualization is limited by poor or absent uterine descent, obesity, or other factors that make an approach to the uterine pedicles difficult. When factors occur that make application or visualization of conventional vaginal instruments difficult, using an instrument designed for laparoscopic application, with its thin, elongated shape, may permit continuation of a vaginal approach. In such a case, a Gyrus bipolar laparoscopic cutting forceps was used for coagulation and transection of the uterine pedicles during a vaginal hysterectomy. This represents a way to expand on traditional techniques for completion of difficult vaginal hysterectomy, which may be used concurrently. Surgical techniques that more easily and safely permit completion of hysterectomy by the vaginal approach can improve outcomes for all.

Examining interactions between biomeds and caregivers

Quality healthcare delivery is a team effort requiring trust, mutual respect and a little professional courtesy when stress levels are high and equipment problems arise. Trust and professional respect are best established through other means like committees or special projects done together rather than the heat of a crisis, yet bonds created during difficulties are some of the strongest. Biomedical technicians equipped with an attitude of patience and humility can contribute to a positive learning experience when the problem lies with the equipment operator.
