Abdominal wall endometriomas.

OBJECTIVE: To investigate the clinical characteristics, treatment, and factors of recurrence of abdominal wall endometriomas (AWE). METHOD: Sixty-four cases of AWE diagnosed at Peking Union Medical College Hospital (PUMCH) from 1983 to 2003 were reviewed retrospectively. RESULT: There was an AWE incidence of 0.044% among the parturients undergoing cesarean section at PUMCH, of whom 87.5% had the typical complaint of an enlarging mass and pain during menstruation. Among these women, 62 underwent low abdominal surgery for endometrioma (2 for primary umbilicus endometrioma); 2 women with small endometriomas opted for a temporary medical solution and had relief after menopause. The latent period of AWE positively correlated to the women's age at onset of symptoms (P<0.001). Of the 62 women who underwent local excision, 19 had an unsatisfactory experience with medical management. There were 5 recurrences and 1 evolution to malignancy during a mean follow-up of 83.7 months. Recurrence was closely related to the size and depth of lesions. CONCLUSION: Because of its typical clinical manifestations, abdominal wall endometriomas could be diagnosed before pregnancy. Surgical excision is the only effective treatment and wide local excision with clear margins is the key point to prevent recurrence.

[Clinical analysis of 11 cases with perineal endometriosis].

OBJECTIVE: To report the diagnosis and treatment of 11 cases with perineal endometriosis (PE). METHODS: Eleven patients with PE treated in our department from 1983 - 2000 years were analyzed retrospectively and were followed for 0.5 - 7.0 years. RESULTS: The incidence of PE is 0.37% of total endometriosis cases operated in our department or 0.087 per thousand of total episiotomy undergone in our delivery room during the 18 year period. Their diagnosis were confirmed clinical manifestations and pathological evidences. All except one had history of perineal tear and episiotomy. The latent period of patient who was less than 30 years old is within one year. The latent period of patient who was more than 30 years old is more than one years (P < 0.05). Complete surgical excision with a cure rate of 91% (10/11). CONCLUSIONS: PE is mainly diagnosed by clinical manifestations. Surgical excision is the first choice of treatment.

[Congenital vaginal atresia: report of 16 cases].

OBJECTIVE: To analyze the clinical features of congenital vaginal atresia (CVA) with normal uterine corpus and investigate the relationship between the subtypes and management. METHODS: Sixteen cases, partical atresia (type I) 10 and complete atresia (type II) 6, treated in Peking Union Medical College Hospital, during the past 16 years, were analysed retrospectively. RESULTS: Patients with type I CVA had an earlier onset of symptoms [(13.0 +/- 1.1) years of age], duration of [(3.5 +/- 2.4) months], greater pelvic masses [(7.7 +/- 3.0) cm in diameter] with lower location as compared with type II CVA [(15.5 +/- 3.4) years of age, 24.0 months, (5.3 +/- 1.0) cm in diameter, P < 0.01]. Distal colpoplasty was performed on 10 type I cases and vaginal mold was placed postoperatively. Dysmenorrhea relieved in all cases during median 21 month follow-up. Vaginal dilatation was done in 4 cases due to readhesion and constriction. One out of the 2 married patients delivered viable neonate by cesarean section. Three out of 6 type II patients were complicated with either endometriosis or hematosalpinx or double uterus. Hysterectomy with or without colpoplasty was done. While the other 3 underwent colpoplasty and cervical canalization. Only 2 had menses after operation, but 1 of the developed dysmenorrhea, ovarian endometrioma and was treated surgically again, the other 1 had hypomenorrhea. CONCLUSION: Patients with type I CVA had better outcomes after colpoplasty if they persist on placing vaginal mold. While for type II CVA, hysterectomy usually needed in most cases.

[Laparoscopic surgery in patients with hypovolemic shock due to ectopic pregnancy].

OBJECTIVE: To evaluate the feasibility and safety of operative laparoscopy for ectopic pregnancy with hypovolemic shock. METHODS: Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. Group I included 21 patients of ectopic pregnancy with shock and intraperitoneal hemorrhage more than 1,000 ml, and group II included 194 hemodynamically stable patients with blood loss less than 1,000 ml. The clinical data of perioperative periods in two groups were analyzed. RESULTS: All patients were tube pregnancies. The rate of tube rupture was higher in group I than that in group II (81% versus 16%), the difference was statistically significant (P < 0.01). Intraabdominal blood loss was significantly higher in group I (1,775 +/- 531) ml than that in group II (133 +/- 176) ml, autologous blood transfusions were given to 95% and 9% of patients in group I and II respectively (P < 0.01). Laparoscopic salpingectomy was performed to 86% and 51% of patients in group I and II, the difference was significant. The operating time was longer in group I than in group II (50 +/- 24) and (43 +/- 24) min, but the difference was not significant. All patients had no perioperative complications. CONCLUSIONS: Operative laparoscopy in patients with hypovolemic shock can be safely and effectively performed by experienced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring and autologous blood transfusion.
