Hernia and abdominal wall surgery is a relatively new subspecialty in surgery. Although it started late in China, after 25 years of rapid development, it has made remarkable achievements and has become an important part of surgery, laying a solid foundation for the further development of the discipline. At the same time, one should also be soberly aware of the present deficiencies in this field. The development of the field should be more detailed and in-depth from the following aspects: correct understanding of new concepts of hernia and abdominal wall surgery, establishment of hernia patient registration and quality control system, technological innovation and development of technical equipment, especially the expansion of robot surgical systems, materials science progression to hernia and abdominal wall surgery. Faced with this challenge, China is expected to achieve high-quality development in the field of hernia and abdominal surgery.

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.

Complex ventral hernia refers to a large hernia that is complicated by a series of concurrent conditions. Change in intra-abdominal pressure is one of the main pathways through which various factors exert an impact on perioperative risk and postoperative recurrence. Taking abdominal pressure reconstruction as the core, the treatment strategy for complex abdominal hernia can be formulated from three aspects: improving patients' tolerance, expanding abdominal cavity volume, and reducing the volume of abdominal contents. Improving patients' tolerance includes abdominal wall compliance training and progressive preoperative pneumoperitoneum. To expand the volume of the abdominal cavity, implanting hernia repair materials, component separation technique, autologous tissue transplantation, component expend technique, and chemical component separation can be used. Initiative content reduction surgery and temporary abdominal closure may be performed to reduce the volume of abdominal contents. For different cases of complex ventral hernia, personalized treatment measures can be safely and feasibly adopted depending on the condition of the patients and the intra-abdominal pressure situation.

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.

Objective: To compare laparoscopic Keyhole repair with Sugarbaker repair in consecutive patients with parastomal hernia. Methods: From January 2015 to December 2021, 117 patients with parastomal hernia were treated with Keyhole or Sugarbaker laparoscopy repairs in the Department of Hernia and Bariatrci Surgery, the First Affiliated Hospital of University of Science and Technology of China, and the clinical data were retrospectively analyzed. There were 45 males and 72 females, aged (68.6±8.6) years (range: 44 to 84 years). Laparoscopic Sugarbaker repair was performed in 89 cases, and Keyhole repair was performed in 28 cases. The t-test, Mann-Whitney U test, χ² test and Fisher exact test were used to compare the observation indicators between the two groups, such as operation time, incidence of operation-related complications, and postoperative recurrence rate. Results: The follow-up period was (M(IQR)) 33 (36) months (range: 12 to 84 months). Compared to the Sugarbaker group, the hernia ring area of the Keyhole group was bigger (35 (26) cm² vs. 25 (16) cm², Z=1.974, P=0.048), length of stay was longer ((22.0±8.0) d vs. (14.1±6.2) d, t=5.485, P<0.01), and the postoperative rate of recurrence was higher (28.6% (8/28) vs. 6.7% (6/89), χ²=7.675, P=0.006). There was no difference in operation time and postoperative complications between the two groups. Conclusions: Laparoscopic Sugarbaker repair is superior to Keyhole repair in the recurrence rate of parastomal hernia treated with compsite mesh (not funnel-shaped mesh). There are no differences in operation time and postoperative complications between the two groups.

INTRODUCTION: The superiority of laparoscopic repair over open repair of incisional hernias (IHs) in the elective setting is still controversial. Our study aimed to compare the postoperative outcomes of laparoscopic and open elective IH repair in an Asian population. METHODS: This retrospective study was conducted in an acute general hospital in Singapore between 2010 and 2015. Inclusion criteria were IH repair in an elective setting, IHs with diameter of 3-15 cm, and location at the ventral abdominal wall. We excluded patients who underwent emergency repair, had recurrent hernias or had loss of abdominal wall domain (i.e. hernia sac containing more than 30% of abdominal contents or any solid organs). Postoperative outcomes within a year such as recurrence, pain, infection, haematoma and seroma formation were compared between the two groups. RESULTS: There were 174 eligible patients. The majority were elderly Chinese women who were overweight. Open repair was performed in 49.4% of patients, while 50.6% underwent laparoscopic repair. The mean operation time for open repair was 116 minutes (116 ± 60.6 minutes) and 139 minutes (136 ± 64.1 minutes) for laparoscopic repair (P = 0.079). Within a year after open repair, postoperative wound infection occurred in 15.1% of the patients in the open repair group compared to 1.1% in the laparoscopic group (P = 0.0007). Postoperative pain, recurrence and haematoma/seroma formation were comparable. CONCLUSION Elective laparoscopic IH repair has comparable outcomes with open repair and may offer the advantage of reduced postoperative wound infection rates.

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.

Direct suture repair with mesh reinforcement is the main surgical procedure in ventral hernia repair. The best place for mesh implantation is retromuscular space which means sublay. The most commonly used techniques are open sublay and laparoscopic IPOM repair. But open sublay repair may cause more trauma to the abdominal wall and result in more infections. Laparoscopic IPOM repair carries an increased risk in bowel injury, mesh-related complications and postoperative pain. Germany surgeon Reinpold developed a new technique defined as "MILOS concept" by combining the advantages of open sublay and laparoscopic IPOM repair. This technique uses mini or less incision hybrid with endoscopic technique to accomplish minimally invasive sublay repair. The MILOS operation has the advantages of less operative trauma, fewer postoperative complications, low recurrence rate and high economic efficiency. "MILOS concept" has been applied with several modifications by using endoscopic technique (EMILOS and eTEP) or robotic surgery. This new minimal invasive ventral hernia repair technique is accepted and applied in clinical practice by most surgeons worldwide. Several literatures already reported that this procedure had very good surgical outcomes, and confirmed its value in further popularization.

OBJECTIVETo observe the safety and efficacy of biological patch (Biodesign Surgisis mesh, SIS) in hybrid technique for incisional herniorrhaphy.

METHODSClinical and follow-up data of 14 incisional hernia patients who underwent incisional herniorrhaphy with hybrid technique, using porcine small intestinal submucosa acellular matrix patch, at the First Affiliated Hospital of Sun Yat-sen University from January 1, 2012 to June 31, 2016 were analyzed retrospectively. This Biodesign Surgisis patch for incisional hernia is produced by the Cook company in the United States. The size of patch ranged from 9 cm × 15 cm to 20 cm × 25 cm. During operation, according to abdominal wall defect, the patch was cut to ensure the distance from its edge to the border of abdominal wall defect more than 5 cm.

RESULTSThere were four male and tenfemale patients with average age of (67.7±11.6) years and average body mass index(BMI) of (25.5±1.7) kg/m². As for operative history of these 14 cases, 7 cases had gastrointestinal tumor surgery, 2 had appendectomy, 1 had upper abdominal white line hernia repair, 1 had hysterectomy, 1 had cholecystectomy, 1 had splenectomy plus portal vein dissection, and 1 had right kidney and right ureter total resection plus partial excision of bladder wall. Ten casesdeveloped incisional infection after previous surgery. The duration of incisional hernia ranged 1 to 180 months (median, 8 months). Two cases were refractory hernia, 1 was incarcerated hernia, and 11 were reversible hernia. The locations of incisional hernia included 4 cases of right ventral wall, 1 case of left ventral wall, 2 cases of supra-umbilical incision, 4 cases of infra-umbilical midline incision, and 3 cases of peri-umbilical midline incision. There were 3 cases of middle incisional hernia, 5 cases of large incisional hernia and 6 cases of huge incisional hernia. All the patients completed operations eventlessly. The average operative time was (202.5±72.9) minutes. The average length and width of hernia ring were (10.9±4.3) cm and (9.3±3.9) cm, respectively. Clean operation was performed in 11 cases, potential contaminative operation in 2 cases and contaminative operation in 1 case. The amount of operative bleeding was (15.0±4.8) ml. The NRS pain scores within 24 hours after the operation, at POD3 and at POD7 were 5.1±0.9, 4.2±0.7 and 3.7±0.9, respectively. The time to flatus after operation was (2.5±0.9) days and the time to liquid diet was (3.8±1.2) days. No patient died during the perioperative period. The average hospitalization time was (21.5±12.0) days. Postoperative complications occurred in 8 cases, including 4 cases of fever, 8 cases of incision complications, 4 cases of abdominal infection, 4 cases of intestinal obstruction, 5 cases of effusion under patch, 2 cases of pneumonia, and 1 case of acute myocardial infarction. According to the Clavien-Dindo classification, 3 cases were grade zero, 3 cases were grade I(, 6 cases were grade II(, 1 case was grade III(, and 1 case was grade IIII(. Thirteen patients received follow-up and the average follow-up time was (33.2±12.3) (18.2-61.0) months. One patient died of cerebral infarction 38 months after operation. The chronic abdominal pain or discomfort was found in 4 cases. The recurrent incisional hernia developed in 5 cases and the average time of recurrence was (11.0±8.3) months.

CONCLUSIONSBiological patch can be used safely and effectively in hybrid technique for incisional herniorrhaphy. However, the morbidity of postoperative complication and the risk of recurrence are high. Terefore, the long-term outcome is still subject to observation.
