Parastomal hernia is a common complication after abdominal ostomy. Although the European Hernia Society guidelines recommend surgical treatment for parastomal hernia, there is still no "gold standard" procedure. The exploration and practice of parastomal hernia repair surgery has been carried out for many years, from the earlier hernia ring suture and stoma relocation repair, to the reinforcement of meshes (such as the Keyhole repair technique and the Sugarbaker repair technique) and the application of laparoscopic technique, and then to the combination of various methods. The intervention of single-port laparoscopic technique and robot-assisted surgery, the prevention of parastomal hernia, the specialization of treatment, multidisciplinary cooperation, and the improvement of diagnostic methods will all provide more optimal solutions for stoma patients. This article will review and summarize the development process and evaluation of parastomal hernia surgical techniques.

Parastomal hernia is one of the common complications of stoma surgery with an incidence of more than 30%, which can be diagnosed by physical examination and abdominal CT. Risk factors of parastomal hernia might include stoma approaches including the selection of intestine, relationship between stoma and peritoneum, stoma location, aperture size, operation time and the patient's own conditions. It is essential to prevent parastomal hernia in order to improve patients' quality of life. Prophylactic mesh and perioperative care might prevent parastomal hernias. The mesh type might also influence the incidence of parastomal hernia. To reduce the incidence of recurrence of parastomal hernia, placement of mesh by the laparoscopic Sugarbaker technique was an effective surgical approach. How to prevent and repair parastomal hernia and cure parastomal hernia repair still needs further high-quality research to provide evidence.

3.Clinical value of mesh prophylaxis for parastomal hernia based on evidence-based medicine.
Chinese Journal of Surgery 2023;61(6):446-450
The incidence of parastomal hernia is substantially high, significantly affecting the quality of life of patients with stoma. How to effectively solve the problem of parastomal hernia is a long-term focus of hernia and abdominal wall surgery and colorectal surgery. The European Hernia Society guidelines on prevention and treatment of parastomal hernia published in 2018 has recommended the use of a prophylactic mesh to prevent parastomal hernia for the first time. In the following 5 years, more randomized controlled trials of multi-center, large-sample, double-blind, long-term follow-up have been published, and no significant effect of mesh prophylaxis has been observed on the incidence of parastomal hernia. However, whether mesh could decrease surgical intervention by limiting the symptoms of parastomal hernias would become a potential value of prophylaxis, which requires further research to elucidate.

BACKGROUND:
It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.
METHODS:
A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided).
RESULTS:
The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107).
CONCLUSIONS:
The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly.

BACKGROUNDAlthough repair augmented with mesh has been proved its priority in anatomical and functional recovery after anterior compartment reconstruction, the data about posterior compartment are scarce. The aim of this study was to compare bowel functional outcome of posterior vaginal compartment repair with and without mesh in patients with pelvic organ prolapse (POP).
METHODSThis was a prospective, double-blind, clinical pilot study of 22 postmenopausal women with symptomatic POP (overall POP-quantification [POP-Q] Stage III-IV) who underwent total pelvic floor reconstruction. Patients were grouped according to the use of mesh for posterior vaginal compartment repair: A mesh group and a nonmesh group. POP-Q stage, the pelvic floor impact questionnaire short form-7 (PFIQ-7) and anorectal manometry were evaluated before and 3 months after surgery. Anatomical success was defined as POP-Q Stage II or less. A t-test was used to compare preoperative with postoperative data in the two groups.
RESULTSTotally, 17 (71%) were available for the follow-up. POP-Q measurements improved significantly compared to baseline (P < 0.05) in both groups. No recurrence was observed. Subjects in both groups reported improvement in pelvic floor symptoms, and there was no significant difference in the PFIQ-7 score between groups at follow-up (P > 0.05). Compared with baseline, the nonmesh group exhibited a statistically significant decrease in anal residual pressure, a significant increase in the anorectal pressure difference during bowel movement, and a reduced rate of dyssynergia defecation pattern (P < 0.05).
CONCLUSIONSProvided there is sufficient support for the anterior wall and apex of vagina with mesh, posterior compartment repair without mesh may be as effective as repair with mesh for anatomical recovery while providing better anorectal motor function.

7.Chinese expert consensus on the diagnosis and surgical treatment of rectal prolapse (2022 edition).
Chinese Journal of Gastrointestinal Surgery 2022;25(12):1081-1088
Surgery is currently the only cure for rectal prolapse. Standardized preoperative evaluation and appropriate selection of surgical methods are crucial to the outcome of rectal prolapse surgery. With the development of a series of clinical studies in China and abroad, transabdominal surgery (such as ventral mesh fixation) and transperineal (anal) surgery (such as Altemeier surgery) have been widely recognized. Precise preoperative assessment of rectal prolapse and appropriate selection of surgical approaches has important clinical value in reducing postoperative recurrence rates and surgical-related complications. However, the current rectal prolapse assessment system needs to be improved, and the choice of surgical procedures remains controversal. To guide the diagnosis and surgical treatment of patients with rectal prolapse in China, nationwide specialists of colorectal and pelvic floor surgery have been organized by the of Chinese Medical Doctor Association Anorectal Branch, the Pelvic Floor Surgery Committee, and Clinical Guidelines Committee. Experts have conducted rounds of discussions on the core content of standardized diagnosis and surgical treatment for rectal prolapse, and jointly formulated the "Chinese expert consensus on the diagnosis and surgical treatment of rectal prolapse (2022)". We hope that this consensus will provide useful resources for the colorectal and pelvic floor surgeons, and promote the standardization of diagnosis and surgical treatment for the rectal prolapse in China.

BACKGROUNDQuadratus femoris pedicled bone grafting has yielded satisfactory long-term clinical outcome for osteonecrosis of the femoral head (ONFH) in pre-collapse ONFH without extensive lesion. However, for pre-collapse ONFH with extensive necrotic area, it is still challenging to preserve the femoral head. The current study aimed to introduce a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus and to evaluate its short-term outcomes.
METHODSFrom January 2008 to December 2008, 10 ONFH patients (12 hips) underwent operations by a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus (group A). According to the ARCO classification system, there were two hips in stage II B and 10 hips in stage II C. Also in the same period, 12 ONFH patients (16 hips) underwent operations by the conventional procedure of quadratus femoris pedicled bone grafting (group B). There were 6 hips in stage II B and 10 hips in stage II C. All patients were males and suffered from alcohol induced ONFH. For the new technique, the necrotic area was evaluated, and a titanium mesh piece of the same size (range from 2.5 cm × 2.8 cm to 2.8 cm × 3.4 cm) was obtained and shaped to match the contour of the head. The cancellous bone was first placed underneath the subchondral bone and was densely impacted (about 1 to 2 mm thick). Then the titanium mesh piece was inserted. The length of the decompressive trough was measured. A titanium cylinder mesh cage with a diameter of 1.6 cm of the same length was obtained, with a "U" shaped window in the wall being created to make room for the muscle pedicle. The muscle pedicle bone was inserted into the titanium mesh cage to form a bone graft-titanium cage complex and, then the complex was inserted. The hundred percent score method was used for outcome evaluation. Clinical and radiographic outcomes were compared between group A and group B.
RESULTSThe average operative time was 150 minutes (130 to 185 minutes) in group A, with an average of 130 minutes (120 to 180 minutes) in group B. The mean blood loss was 400 ml (300 to 500 ml) in group A and 350 ml (250 to 500 ml) in group B. Group A patients were followed up for an average of 19.2 months (14 to 24 months), with an average of 18.5 months (12 to 24 months) for Group B. Full weight bearing was allowed 5 to 7 months postoperatively. Pain and function were obviously improved. For group A, pain score improved from a mean of 9.8 points preoperatively to an average of 24.6 points postoperatively, and function score improved from a mean of 9.0 points preoperatively to an average of 17.4 points postoperatively. In group B, pain score improved from a mean of 9.5 points preoperatively to an average of 24.2 points postoperatively and function score improved from a mean of 9.2 points preoperatively to an average of 17.2 points postoperatively. The range of motion changed the least, with score improvement from a preoperative mean of 13.9 points to postoperative 16.8 points for group A and from a preoperative mean of 13.7 points to postoperative 16.5 points for group B. Radiographic score improved from preoperative 31 points to postoperative 38 points for group A, in comparison with an improvement from preoperative 31 points to postoperative 37 points for group B. At the latest follow up, 11 hips were rated as excellent and 1 hip was better for group A, with 14 hips being rated as excellent and 2 hips being better in group B. There was no statistically significant difference between groups A and B in clinical and radiographic outcomes.
CONCLUSIONFor ONFH in stage ARCO IIC, satisfactory clinical outcome can be achieved by the new technique in the short-term period while the long-term clinical outcome has yet to be determined.

Objective: To examine the preliminary effect of laparoscopic extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis for the prevention of parastomal hernia after abdominoperineal resection for rectal cancer. Methods: This study is a prospective case series study. From June 2021 to June 2022, patients with low rectal cancer underwent laparoscopic abdominoperineal resection combined with extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis at the First Department of General Surgery, Shaanxi Provincial People's Hospital were enrolled. The clinical data and postoperative CT images of patients were collected to analyze the incidence of surgical complication and parastomal hernia. Results: Totally 6 cases of patient were enrolled, including 3 males and 3 females, aging 72.5 (19.5) years (M(IQR)) (range: 55 to 79 years). The operation time was 250 (48) minutes (range: 190 to 275 minutes), the stoma operation time was 27.5 (10.7) minutes (range: 21 to 37 minutes), the bleeding volume was 30 (35) ml (range: 15 to 80 ml). All patients were cured and discharged without surgery-related complications. The follow-up time was 136 (105) days (range: 98 to 279 days). After physical examination and abdominal CT follow-up, no parastomal hernia occurred in the 6 patients up to this article. Conclusions: A method of laparoscopic extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis is established. Permanent stoma can be completed with this method safely. It may have a preventive effect on the occurrence of parastomal hernia, which is worthy of further study.
