A warm-up laparoscopic exercise improves the subsequent laparoscopic performance of Ob-Gyn residents: a low-cost laparoscopic trainer.

INTRODUCTION: Residents traditionally acquire surgical skills through on-the-job training. Minimally invasive laparoscopic techniques present additional demands to master complex surgical procedures in a remote 2-dimensional venue. We examined the effectiveness of a brief warm-up laparoscopic simulation toward improving operative proficiency. METHODS: Using a "Poor-Man's Laparoscopy Simulator," 12 Ob/Gyn residents and 12 medical students were allocated 10 minutes to transfer 30 tablets with a 5-mm grasper from point A to point B via laparoscopic visualization in a warm-up exercise. Participants repeated the exercise following a 5-minute pause. Mean scores, expressed in seconds/tablet, and overall improvement (percentage difference between warm-up and follow-up) were analyzed according to postgraduate standing (PGY14), dexterity skills, and pertinent vocational activities. RESULTS: Significant improvements were noted for both residents (+25%) and medical students (+29%), P<0.0001. Scores between the 2 groups, however, were not significant (P=0.677). Proficiency was not influenced by PGY standing. Interestingly, the best (8.73 sec/pill) and the worst (25 sec/pill) scores were attained by a medical student and a chief resident, respectively, suggesting the contribution of individual aptitude. CONCLUSION: A brief warm-up exercise before an actual laparoscopic surgical procedure significantly improves subsequent laparoscopic performance.

Placement of a Word catheter: a resident training model.

OBJECTIVE: The present study developed and evaluated a practical teaching model and training protocol for Word catheter placement in the treatment of a Bartholin gland cyst. STUDY DESIGN: Residents were asked to treat a model of the female perineum, fashioned from harvested porcine tissue, with a simulated Bartholin cyst via Word catheter placement and drainage. Each resident was evaluated for procedural competence. They were retested after the viewing of a continuous 59-second video demonstrating catheter placement. RESULTS: The model's resemblance to female genitalia was confirmed by 68% of residents. Correct diagnosis and treatment of a Bartholin gland cyst was made by 61%. The mean pretraining score was 5.5 +/- 1.46, while the post-training average was 8.2 +/- 1.20, indicating an approximate 58% increase in resident proficiency (P < .05). CONCLUSION: A model of the female perineum fashioned from harvested porcine tissue is a suitable instructional aid in the recognition and treatment of a Bartholin cyst. Proficiency in Word catheter placement is improved through the use of the model and instructional video.

Sexual response in the patient after hysterectomy: total abdominal versus supracervical versus vaginal procedure.

OBJECTIVE: The present study examines the patient's own appraisal of her sexual responsiveness after hysterectomy. STUDY DESIGN: Four hundred women who had undergone hysterectomy within a 3-year period were selected randomly and asked to respond to a questionnaire that was devised to ascertain the patient's own objective evaluation of self-image, sexuality, and sexual response before and after hysterectomy. The confidential responses were analyzed, noting the presence of any significant divergence between demographic and procedural cohorts. RESULTS: Of 126 respondents, 48.4% underwent total abdominal hysterectomy; 34.1% underwent vaginal hysterectomy, and 17.4% underwent supracervical hysterectomy. The mean patient age was 49.7+/-8.7 years. No direct correlation was found between hysterectomy type and age. Most women did not report any significant deterioration in mental attitude after the procedure (P =.788). Self and body image also remained consistent, with only 25.3% indicating a change for the worse. Only 10.3% of respondents felt less feminine after hysterectomy; nearly 70% of the respondents did not feel less feminine. Responses that pertained to libido, sexual activity, or feelings of femininity did not reveal significant changes (P >.05). Satisfaction with procedural choice was positive (54.8%), with only 7.1% responding unfavorably. CONCLUSION: The responses suggest that neither self-image nor sexuality need diminish after hysterectomy. The type of hysterectomy that was performed did not appear to affect the attitudes of the respondents.

Obstetric predictors of placental/umbilical cord blood volume for transplantation.

OBJECTIVE: Umbilical cord blood is an effective alternative to bone marrow as a source of hematopoietic stem cells in transplantation. However, the amount of donor blood and the cell content that are collected may be insufficient for engraftment in some adult recipients. This study identifies obstetric factors that affect retrievable placental cord blood volume. STUDY DESIGN: A retrospective analysis of factors that were obtained by direct observation or medical record review that were related to harvested cord blood volume was conducted; the analysis involved 9205 deliveries from mothers who donated placental cord blood through the obstetric services of two New York City hospitals between 1993 and 1999. RESULTS: Obstetric factors that influenced significantly the total volume of blood that was collected were route of delivery, induction of labor, presence of a nuchal cord, infant birth weight, multiple births, placental weight, and duration of labor. The length of the umbilical cord from the venipuncture site and the length of time to cord blood collection also affected the volume that was retrieved. Maternal ethnicity was associated with cord blood yield; Caucasian mothers provided larger quantities than either African American or Asian mothers. CONCLUSION: Our results confirm that the volume of residual placental cord blood that is collected for hematopoietic stem cell transplantation is influenced by several factors, the presence of which predict the likelihood of an adequate collection. Collected volumes can be improved when a longer length of the cord is left with the placenta and when there is a shorter time between the delivery of the placenta and the collection.
