Does obesity affect the vaginal hysterectomy outcomes?

OBJECTIVE: To evaluate the effects of obesity on the perioperative outcomes in women who underwent vaginal hysterectomy. STUDY DESIGN: In this retrospective cohort study of all women who underwent vaginal hysterectomy for benign disorders at Temple University from January 1997 to December 2002, perioperative indices were compared between 149 obese (BMI ≥ 30 kg/m(2)) and 175 non-obese women (BMI < 30 kg/m(2)). RESULTS: The groups were similar with respect to age, parity, uterine weight, race, surgical indication, and previous pelvic surgery. Among medical conditions, hypertension and diabetes were significantly more common in obese women. Conversion to laparotomy occurred at similar rates in both obese (3.3%) and non-obese (5.7%) women. There was no significant difference between the groups regarding the operative time, length of hospital stay, transfusion rate, perioperative hemoglobin change, and perioperative complications (p < 0.05). CONCLUSION: Obesity does not affect the perioperative outcomes and surgical complications of vaginal hysterectomy.

The effect of obesity on total abdominal hysterectomy.

OBJECTIVE: To compare perioperative outcomes of total abdominal hysterectomy (TAH) between obese and nonobese women. METHODS: The medical charts of all women who underwent TAH for benign gynecological conditions at Temple University Hospital between 1997 and 2002 were reviewed. We excluded those who had concomitant surgery except for adnexal removal. The rates of perioperative indices were compared between obese (body mass index [BMI] ≥ 30 kg/m²) and nonobese women; p < 0.05 was considered significant. RESULTS: Of 357 women, 172 (48.2%) were obese, and 185 (51.8%) were not. Among the baseline characteristics, only race was statistically different between the groups. There were more African American women among the obese women (82.5% vs. 70%, p < 0.05). Postoperative complications, including urinary tract injury, were not significantly increased in the obese group. On the contrary, nonobese women had a significantly higher incidence of ileus (13.5% vs. 6.4%, p < 0.05). Although operative time was significantly prolonged for obese women, obesity did not increase the length of hospitalization, transfusion rate, and perioperative hemoglobin change. All these results remained the same even after controlling for race. CONCLUSIONS: Contrary to the general opinion, obesity does not significantly affect the perioperative outcomes for TAH performed for benign gynecological causes.

Is prior uterine surgery a risk factor for adenomyosis?

OBJECTIVE: The objective of our study was to assess whether prior uterine surgery is a risk factor for adenomyosis. METHODS: Medical records of women who had a hysterectomy for benign conditions between January of 1995 and June of 2002 were reviewed. Women with and without adenomyosis were compared with respect to history of prior uterine surgery, such as cesarean delivery, myomectomy, endometrial ablation, dilation and evacuation, and dilation and curettage. RESULTS: Of 873 completed records available, 412 patients (47.1%) had adenomyosis. Mean age and race distribution were similar between the 2 groups. The group with adenomyosis had significantly higher gravidity (P < .001) and parity (P = .004), but smaller uterine size (P < .001) and uterine weight (P < .001). Univariable analysis for each aforementioned specific surgical procedure did not indicate a significant difference between women with and without adenomyosis. However, history of any prior uterine surgery increased the risk of adenomyosis (48.8% and 41.0%, odds ratio 1.37, 95% confidence interval 1.05-1.79) on univariable analysis. This association remained significant when all of the factors were combined in a multivariable logistic regression model. CONCLUSION: In this study, we found a significantly increased risk of adenomyosis with prior uterine surgery. The absence of significant association with any specific surgical procedure is possibly the result of a smaller number of subjects in each individual group. LEVEL OF EVIDENCE: II-3.

Hysterectomy in obese women: a comparison of abdominal and vaginal routes.

OBJECTIVE: To compare perioperative outcome measures of abdominal and vaginal hysterectomies in obese women. METHODS: We reviewed the charts of all obese women (body mass index more than 30 kg/m(2)) who underwent abdominal or vaginal hysterectomy for benign gynecologic conditions in our institution between 1997 and 2002. Laparoscopically assisted vaginal hysterectomies and hysterectomies with concomitant major pelvic or abdominal surgery were excluded. The rate of operative and postoperative complications, length of hospitalization, operative time, and perioperative change of hemoglobin concentration were analyzed for abdominal hysterectomy and vaginal hysterectomy. RESULTS: The study group consisted of 369 obese women, of whom 189 (51.2%) underwent abdominal, and 180 (48.8%), vaginal hysterectomy. Patient characteristics were statistically comparable between the groups except for uterine weight, which was higher in the abdominal group, and parity, which was greater for women who underwent vaginal hysterectomy (P <.05). After controlling for all the significantly different variables, vaginal hysterectomy resulted in lower incidence of postoperative fever (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.12-0.39), ileus (OR 0.21, 95% CI 0.06-0.75), urinary tract infection (OR 0.21, 95% CI 0.06-0.75), shorter operative time (126.8 +/- 58.7 minutes compared with 109.7 +/- 68.5 minutes) and length of hospital stay (3.5 +/- 1.9 days compared with 1.9 +/- 1.1 days). Seven women (3.7%) who underwent abdominal hysterectomy developed wound infections during their hospital stay compared with none in the vaginal hysterectomy group. CONCLUSION: For obese women, vaginal hysterectomy is superior due to its lower incidence of postoperative fever, ileus, and urinary tract infection and shorter operative time and hospital stay.
