    <B>Objective:</B> This study was conducted to assess the validity of laparoscopic lymphadenectomy for gynecologic malignancies at our hospital.<BR><B>Methods:</B> Twenty-five patients undergoing laparoscopic (LS) paraaortic and pelvic lymphadenectomy for endometrial carcinoma were compared with 21 control subjects similarly treated via laparotomy (LT). Only surgeries involving systematic lymphadenectomy were included. Extracted lymph nodes were classified using The General Rules for Clinical and Pathological Management of Uterine Cervical Cancer<SUP>1)</SUP>.

    <B>Objective:</B> Considered to be a cause of unexplained chronic pelvic pain, appendiceal endometriosis is relatively rare, accounting for only 3% of all pathologic lesions of this disorder. In this study, we analyzed the clinicopathologic findings of resected appendices with an abnormal appearance discovered during laparoscopic surgery for endometriosis.<BR><B>Patients and Methods:</B> We performed laparoscopic surgery on 309 patients with endometriosis between January 2006 and December 2008 in Hokkaido University Hospital and its affiliated hospitals. Nineteen patients underwent laparos..., Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy, Japanese

    <B>Objectives:</B> The aims of this study were to report the feasibility of laparoscopic surgery for early-stage endometrial cancer and to assess the effects of laparoscopic surgery on the survival of patients.<BR><B>Methods:</B> Twenty-three patients with clinical stage I and IIa endometrial cancer were treated by laparoscopy (laparoscopy group [LS]). The surgical procedures included hysterectomy, salpingo-oophorectomy, and para-aortic-pelvic lymphadenectomy. Peri-operative morbidities and outcomes were compared with 20 control patients who were treated with traditional open surgery (lapar..., Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy, Japanese

    <B>Objectives:</B> The purpose of this study was to determine the feasibility and radicality of endoscopic radical hysterectomy (ERH) and endoscopic modified radical hysterectomy (EmRH) combined with pelvic lymphadenectomy (ELND) in invasive cervical cancer patients.<BR><B>Methods:</B> Five patients with invasive cervical cancer underwent ERH or EmRH between May 2003 and March 2007 at Hokkaido University Hospital. Two patients with stage I a adenocarcinoma underwent an EmRH, and two patients with stage I b1 and one patient with stage II a underwent an ERH.

  • Incidence of pulmonary embolism in patients undergoing laparoscopic surgery for gynecologic malignancies

    Objectives: The true incidence of pulmonary embolism (PE) in patients undergoing laparoscopic surgery for gynecologic malignancies is unknown. The aims of this study were to determine the incidence of PE in laparoscopically-treated cancer patients, to compare the results with those treated with open surgery, and to investigate the efficacy of low-dose unfractionated heparin (LDUH) to prevent the occurrence of PE.<BR>Methods: Thirty-three patients with gynecologic malignancies were laparoscopically-treated (laparoscopy group [LS] ) . The procedures included paraaortic-pelvic lymphadenectomy ..., JAPAN SOCIETY OF GYNECOLOGIC AND OBSTETRIC ENDOSCOPY AND MINIMALLY INVASIVE THERAPY, Japanese
  • Total Laparoscopic Myomectomy : Application for Uterine Submucosal Myoma

    Background: Submucosal myoma has been treated with hysteroscopic transcervical resection (TCR) . However, in cases of unstalked submucosal myoma over 3cm in diameter, TCR could lead to not only extended operation time but also extensive thermal damage on endometrium by electrocoagulation. In this study, we validated the feasibility and utility of total Laparoscopic approach for submucosal myoma treatment.<BR>Materials and Methods: Total laparoscopic myomectomy (TLM) was performed on 12 women with submucosal myoma. Our TLM procedure was as follows: a balloon catheter was detained in the uter..., JAPAN SOCIETY OF GYNECOLOGIC AND OBSTETRIC ENDOSCOPY AND MINIMALLY INVASIVE THERAPY, Japanese
  • Experience of pelvic peritonectomy in patients with persistent pelvic pain

    OBJECTIVE: The aim of this study was to assess the efficacy of laparoscopic resection of pelvic peritoneum in addition to conventional laparoscopic uterosacral nerve ablation (LUNA) procedure on the relief of treatment refractory pelvic pain in patients without preoperative diagnosis of endometriosis.<BR>METHODS: We performed laparoscopic peritonectomy combined with LUNA in 13 patients who had not been diagnosed as endometriosis. Intraoperative findings were re-assessed by videos recorded during surgery. Peritoneal specimens were pathologically reviewed.
