The B.Lynch suture to control massive postpartum hemorrhage : Authours present a case of massive postpartum hemorrhages by uterine of a 27 year-old gravida1 woman with stillbirth and severe hemorrhagic shock. All medical emergency treatment and bilateral hypogastric ligation were performed unsuccessful. Hysterectomy was indicated. But there is no reason why to do hysteretomy for a young primipara woman whose child was died. With the B.Lynch compression suture was immediately carried out, we have saved her life and preserve and maintain further her reproductive function.

The superior hypogastric plexus block (SHPB) is used for treating pelvic pain, especially in patients with gynecological malignancies. Various approaches to this procedure have been reported due to the anatomic obstacles of a high iliac crest or large transverse process of the 5th lumbar vertebra. Here, we report a new technique of superior hypogastric plexus block using a unilateral single-needle approach to block the bilateral superior hypogastric plexus with a Tuohy needle and epidural catheter. We have confidence that this new technique can be another option in performing the SHPB when the conventional bilateral approach is difficult to perform.

Total mesorectal excision (TME) is being established as the gold standard for rectal cancer surgery, however sexual and urinary dysfunction is an established risk after TME. By cadaver dissections, we clarify the correct surgical plane for TME and further determine the relation between the surgical plane and pelvic autonomic nerves. It must be noted that the pelvic plexus can be divided into 2 categories: aggregated shape and diffused shape. The latter is in tight contact with visceral fascia, which seems to be inseparable from each other by sharp dissection. Therefore, it is necessary to study the function of different units in pelvic plexus.

The paracolpium or paravaginal tissue is surrounded by the vaginal wall, the pubocervical fascia and the rectovaginal septum (Denonvilliers' fascia). To clarify the configuration of nerves and fasciae in and around the paracolpium, we examined histological sections of 10 elderly cadavers. The paracolpium contained the distal part of the pelvic autonomic nerve plexus and its branches: the cavernous nerve, the nerves to the urethra and the nerves to the internal anal sphincter (NIAS). The NIAS ran postero-inferiorly along the superior fascia of the levator ani muscle to reach the longitudinal muscle layer of the rectum. In two nulliparous and one multiparous women, the pubocervical fascia and the rectovaginal septum were distinct and connected with the superior fascia of the levator at the tendinous arch of the pelvic fasciae. In these three cadavers, the pelvic plexus and its distal branches were distributed almost evenly in the paracolpium and sandwiched by the pubocervical and Denonvilliers' fasciae. By contrast, in five multiparous women, these nerves were divided into the anterosuperior group (bladder detrusor nerves) and the postero-inferior group (NIAS, cavernous and urethral nerves) by the well-developed venous plexus in combination with the fragmented or unclear fasciae. Although the small number of specimens was a major limitation of this study, we hypothesized that, in combination with destruction of the basic fascial architecture due to vaginal delivery and aging, the pelvic plexus is likely to change from a sheet-like configuration to several bundles.

Pelvic visceral pain associated with both cancer and chronic benign conditions may be alleviated by superior hypogastric plexus block (SHPB). The complications of SHPB include infection, bleeding, or intravascular injection because of the adjacent location of the iliac vessel to the route of needle insertion, and pelvic visceral damage. However, acute ureteral obstruction leading to acute renal failure (ARF) as a complication of SHPB has not been reported to date in the literature. We report a patient with ARF that resulted from acute ureteral obstruction following SHPB performed for the relief of lower abdominal pain and tenesmus in metastatic ureter cancer.

Total mesorectal excision (TME) is the gold standard of surgical treatment for mid and low rectal cancer. It aims to improve the oncological outcomes as well as preserve anal sphincter, sexual and urinary function. Compared with sympathetic nerve injury alone, pelvic plexus and neurovascular bundle (NVB) injury has significant effect on postoperative sexual dysfunction, especially erectile function. Since the lateral surgical plane of TME is narrow and densely packed, dissecting outside the plane causes pelvic plexus injury, while dissecting inside it results in residual mesorectum. In this commentary, we review the research progress of lateral fascial anatomy of TME, and describe the anatomical characteristics of rectosacral fascia based on our previous research results. The prehypogastric fascia acts as a "fascia barrier" when dissecting the lateral space constantly from posterior to anterior. In addition, the pelvic plexus fuses with the prehypogastric fascia which is considered as the outer side layer of rectosacral fascia laterally. Thus, the rectosacral fascia should be dissected at the level of S4 vertebral body posterior to the rectum in an arc shape and then enter the superior-levator space. Before dissecting the lateral spaces, the anterior space of the rectum should be dissected first. After an "U" shape cutting of the Denonvilliers' fascia, the lateral space should be dissected from anterior to posterior. Finally, the lateral attachment of rectosacral fascia is transected to ensure the integrity of the mesorectum without damaging the pelvic plexus.

Chronic pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain regardless of its etiology. Sympathetic nerve block is effective and safe for treatment of pelvic visceral pain. One of them, the inferior hypogastric plexus, is not easily assessable to blockade by local anesthetics and neurolytic agents. Inferior hypogastric plexus block is not commonly used in chronic pelvic pain patients due to pre-sacral location. Therefore, inferior hypogastric plexus is not readily blocked using paravertebral or transdiscal approaches. There is only one report of inferior hypogastric plexus block via transsacral approach. This approach has several disadvantages. In this case a favorable outcome was obtained by using coccygeal transverse approach of inferior hypogastric plexus. Thus, we report a patient who was successfully given inferior hypogastric plexus block via coccygeal transverse approach to treat chronic pelvic pain conditions involving the lower pelvic viscera.

PURPOSE: We wanted to study the precise anatomical location of the branches of the pelvic plexus from the sacral root to the cavernous nerve. MATERIALS AND METHODS: We performed microdissection on the pelvises from 4 male formalin fixed cadavers under a Zeiss surgical microscope and we traced the location of the branches of the pelvic plexus at a magnification of 6x. RESULTS: The configuration of the pelvic plexus was an irregular diamond shape rather than rectangular. It was located retroperitoneally on the lateral wall of the rectum 8.2 to 11.5cm from the anal verge. Its midpoint was located 2.0 to 2.5cm from the seminal vesicle posterosuperiorly. A prominent neurovascular bundle (NVB) was located on the posterolateral portion of the apex and the mid portion of the prostate. The pelvic splanchnic nerve (PSN) joined the NVB at a point distal and inferior to the bladder-prostate (BP) junction. The PSN components joined the NVB in a spray-like distribution at multiple levels distal to the BP junction. The distance from the membranous urethra to the NVB was 0.5 to 1.2cm. We also found multiple tiny branches on the anterolateral aspect of the prostate apex. CONCLUSIONS: In contrast to the usual concept, the NVB was much wider above the mid portion of the prostrate and it supplied multiple tiny branches on the anterolateral aspect of the prostate. The PSN branches arose from the more posteroinferior area of the pelvic plexus. Therefore, we recommend a more anterior dissection of the lateral pelvic fascia for nerve sparing radical prostatectomy. If surgeons plan a nerve graft after radical prostatectomy, they should consider this neuroanatomy for obtaining a successful outcome.

Optimal goals of rectal cancer surgical treatment should include appropriate local control, higher survival rates, scrupulous operation procedures and good quality of life with maintained sexual and voiding function through the conservation of anal sphincter. Complete surgical removal of rectal cancer mass and adjacent lymph nodes in en-bloc package decreases the risk of local recurrence. Furthermore heightened awareness of better surgical techniques has created much interest in the anatomy involved in total mesorectal excision (TME), with particular focus on the fascial planes, nerve plexuses and their relationship to the surgical planes of excision. Total mesorectal excision focuses on several technical components and the quality of operated specimen. Sharp anatomic pelvic dissection along the visceral pelvic fascia must avoid any breach from the mesorectum haboring metastatic tumor deposits and lymph nodes. Also any coning down or blunt dissection should not be allowed. The rectal cancer mass and its surrounding mesorectum must be removed as one complete unit. Circumferential and distal resection margin must be also adequately obtained. Such sharp pelvic dissection instead of blunt dissection requires precised knowledge of the pelvic anatomy. Studying the hemisected cadevaric pelvis shows a clear relationship between the fascia and rectum. Also pelvic autonomic nerves can be saved to preserve the patient's sexual and voiding functions. Therefore the clincial importances of anatomical structures must be emphasized at each step of surgery. Upon such understanding of techniques, TME was performed in rectal cancer patients routinely and was able to obtain fair oncologic results and improved quality of life regarding sexual and voiding functions.

OBJECTIVETo investigate the clinical value of extended radical resection with nerve- preservation for rectal cancer.

METHODNinety-eight patients with rectal cancer received extended radical resection with nerve- preservation in our hospital. The questionnaire were used to collect the data of the patients urination and sexual function. The survival was analyzed retrospectively.

RESULTS62.3% (61/98) of the patients could erect normally and 57.1% (56/98) of the patients had normal sexual function. The average time of catheterization in 57 patients was 60 hours, the residual urine volume (RUV) was 28 ml and the max-micturition-desire urine volume was 400 ml. The 5-year survival rate of those who underwent extended radical resection with nerve-preservation was 61.2%.

CONCLUSIONExtended radical resection with nerve-preservation,which could decrease the incidences of post-operative urination and sexual dysfunction, and have not affect the survival, was the most optimal operation for rectal cancer.
