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.

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.

With the development of modern surgery, the field of hernia and abdominal wall surgery is undergoing a transformative change, and new techniques, new concepts, and recent progress are being updated, which have motivated the high-quality development of the discipline. In the past two decades, the development of hernia and abdominal wall surgery in China has been recognized by international peers. Many young surgeons have gradually become the main force in the treatment of hernia and leaders in surgical technique. The innovation and development of discipline will never terminate; young surgeons as the main force should seriously think about how to improve their professional qualities. Young surgeons are interested in the innovation of surgical techniques and need to push for a traditional operation on the one hand and an innovative operation on the other. Updates to concepts and acquisition of new materials are more important, which can provide a solid foundation for technological innovation. Young surgeons should start with the basics and classics. Understanding the history and development of new techniques, new concepts and recent progress, and grasping indications of clinical application, is the important part of growing up for young surgeons, which can make surgical treatment more standardized, benefit patients, and promote the progress of Chinese specialized medical education.

Objective: To examine the patterning cropped and shaped mesh repair for perineal hernia after abdominoperineal excision (APE) in rectal cancer. Methods: The clinical data of 8 patients with perineal hernia after APE who accepted surgical treatment in the Department of Hepatopancreatobiliary and Hernia Surgery, the First Affiliated Hospital of Fujian Medical University from March 2017 to December 2022 were retrospectively reviewed. There were 3 males and 5 females, aged (67.6±7.2) years (range: 56 to 76 years). Eight patients developed a perineal mass at (11.3±2.9) months (range: 5 to 13 months) after APE. After surgical separation of adhesion and exposing the pelvic floor defect, a 15 cm×20 cm anti-adhesion mesh was fashioned as a three-dimensional pocket shape to fit the pelvic defect, then fixed to the promontory or sacrum and sutured to the pelvic sidewalls and the anterior peritoneum, while two side slender slings were tailored in front of the mesh and fixed on the pectineal ligament. Results: The repair of their perineal hernias went well, with an operating time of (240.6±48.8) minutes (range: 155 to 300 minutes). Five patients underwent laparotomy, 3 patients tried laparoscopic surgery first and then transferred to laparotomy combined with the perineal approach. Intraoperative bowel injury was observed in 3 patients. All patients did not have an intestinal fistula, bleeding occurred. No reoperation was performed and their preoperative symptoms improved significantly. The postoperative hospital stay was (13.5±2.9) days (range: 7 to 17 days) and two patients had postoperative ileus, which improved after conservative treatment. Two patients had a postoperative perineal hernia sac effusion, one of them underwent placement of a tube to puncture the hernia sac effusion due to infection, and continued irrigation and drainage. The postoperative follow-up was (34.8±14.0) months (range: 13 to 48 months), and 1 patient developed recurrence in the seventh postoperative month, no further surgery was performed. Conclusions: Surgical repair of the perineal hernia after APE can be preferred transabdominal approach, routine application of laparoscopy is not recommended, combined abdominoperineal approach can be considered if necessary. The perineal hernia after APE can be repaired safely and effectively using the described technique of patterning cropped and shaped mesh repair.

No consensus on standardized technique of enterostomy creation has been made meanwhile high heterogeneity of surgical procedure exists in 'stoma creation' chapters of textbooks or atlases of colorectal surgery. The present article reviews the anatomy of tendinous aponeurotic fibers which is crucial for abdominal wall tension and integrity. Through empirical practice we hypothesize a procedure of enterostomy creation basied on abdominal wall tension plus anchor suture for fascia fixation which could theoretically decrease short-term stoma complication rates and long-term parastomal hernia rates. Surgical techniques are as followed: (1) preoperative stoma site mark for de-functioning ileostomy should be positioned at the lateral border of rectus abdominis muscle (RAM) to decrease the difficulty of stoma reversal and for permanent colostomy should be placed overlying the RAM to promote adhesion; (2)Optimal circular removal or lineal opening of skin, and avoid dissection of subcutaneous tissue; (3) Lineal dissection of natural strong fascia (rectus sheath) at stoma site and blunt separation of muscular fibers. The tunnel of the fascia should be made with appropriate size without undue tension. To prevent the formation of dead space, additional suturing at fascia layer is unnecessary. (4) Anchor suture for fascia fixation at two ends of fascia opening could be considered to avoid delayed fascia disruption and parastomal hernia. (5) After pull-through of ileum or colon loop, 4-8 interrupted seromuscular sutures could be placed to attach loop to skin. For ileostomy, self-eversion of mucosa can be successful in vast majority of cases and a Brooke ileostomy is not necessary. The efficacy and safety of this procedure should be tested in future trials.

Trocar placement and camera-dissection in the midline is the most commonly applied method for total extraperitoneal inguinal hernia repair (TEP), for which the theory of membrane anatomy has guiding significance. We hereby applies the theories and concepts, such as "fascia lining", "multi-layer", "inter-fascial planes", "combined inter-fascial plane" and "plane transition", to elucidate the key steps of TEP, for instance, space creation, hernia sac dissection, mesh flattening. Camera-dissection is performed along the posterior sheath of the rectus abdominis. Firstly, the camera enters retro-rectus space locating between the rectus abdominis and the transversalis fascia (TF). There are inferior epigastric vessels and their branches in the retro-rectus space, thus over-dissection should be avoided. Secondly, the camera goes downward through the TF into the pre-peritoneal space. The pre-peritoneal space is divided into the parietal plane and visceral plane by pre-peritoneal fascia (PPF). Both bladder and spermatic cord components locate on the visceral plane. Dissection of the median area should be implemented on the parietal plane, namely "surgical space", to protect the bladder. The parietal plane is the "holy plane" of TEP. Dissection of the indirect hernia area should be implemented on the visceral plane, namely "anatomical space", to protect the spermatic cord components. The reduction of direct hernia could be understood as the easy separation of TF and PPF. The reduction of indirect hernia is relatively difficult separation of peritoneum and spermatic cord components. During the transition of parietal and visceral planes, PPF (especially the pre-peritoneal loop) should be dissected for complete parietalization, in order to flatten the mesh.

Chylous ascites is a rare complication following bariatric surgeries. Little data is available regarding chylous ascites following bariatric surgeries per se or in association with internal hernias. Herein we present two cases of chylous ascites following Roux-En-Y gastric bypass; the first one is a 60-year-old male who was presented to the ER six months after a gastric bypass operation suffering from abdominal pain, CT scan and upper endoscopy were normal, however chylous ascites and internal hernia were found during exploratory laparoscopy. The second case is a 39-year-old female patient who was admitted three years following the gastric bypass operation and diagnosed to have small bowel obstruction due to internal hernia, and during exploratory laparoscopy a chylous ascites was found.

OBJECTIVETo evaluate the safety and feasibility of radical surgery for giant desmoid in abdominal wall accompanied with the repair of giant myofascial defect using synthetic prosthesis.

METHODSWe analyzed the clinical and follow-up data of 31 patients with giant desmoid in abdominal wall undergoing radical resection and immediate abdominal wall reconstruction with synthetic prosthesis from January 2007 to January 2017 retrospectively. Patients were recruited at the Diagnostic and Therapeutic Center of Hernia and Abdominal Wall Diseases, the First Affiliated Hospital of Chinese PLA General Hospital and the Department of General Surgery, Chinese PLA General Hospital. Operative conditions, morbidity of complication, short- and long-term outcomes were summarized. All the patients underwent radical resection and infiltrated organs or tissues were simultaneously treated. Synthetic prosthesis was used to perform primary-intention reconstruction of giant myofascial defect in anterior or lateral abdominal wall. Bridging repair procedure for incisional hernia was used to perform double border fixation between prosthesis border and myofascial defect border. Placement and fixation of prosthesis followed the idea of "conformal repair", then prosthesis was finally repaired as arch in accordance with original abdominal wall.

RESULTSOf 31 patients, 28 cases were female with mean age of 35.2 (16-58) years and 3 were male with mean age of 42.6 (20-79) years. Six initial cases (19.4%) were diagnosed by preoperative biopsy, and 25 recurrent cases (60.6%) were diagnosed by medical history. The mean minimal diameter of tumors was 18.2 (14-25) cm, and the mean maximal diameter was 45.3 (32-53) cm. All 31 patients underwent radical resection and immediate abdominal wall reconstruction using synthetic prosthesis in bridging fashion successfully, and rapid pathological examination showed that all resection margins were negative. The average operative time was 335 (245-610) min, and the average intra-operative blood loss was 1260 (500-3500) ml. The size of abdominal wall defect after removal of desmoid ranged from 21 cm × 23 cm to 35 cm × 60 cm. The defects in 29 patients were repaired with compound synthetic prosthesis and the defects in 2 patients were repaired with compound prosthesis and polypropylene mesh. Four patients(12.9%) developed postoperative infection, in whom 3 patients had prosthesis infection during 1 month postoperatively, then 1 case recovered with conservative therapy, the other 2 cases were healed after the removal of infected prosthesis at 2 weeks and 3 months postoperatively, respectively; 1 patient had infection of artificial vessel prosthesis and received a second operation to remove the infected artificial vessel. The other 27 patients recovered smoothly and got primary intention wound healing. These 31 patients were followed up for a median of 60.5 (10-121) months with complete data. No marginal recurrence, incisional hernia, and abdominal wall bulge happened. One patient undergoing removal of all anterior and lateral abdominal wall had difficult defecation and urination during the first month after operation, and recovered through practising chest breathing. Ten patients developed fresh desmoids in other body positions postoperatively within 1-3 years, in whom 3 patients died of intestinal obstruction due to rapid neoplasm development and 7 patients survived with tumor receiving conservative therapy. All the 28 survival patients could restore normal life and workand have appropriate sports.

CONCLUSIONRadical resection and immediate reconstruction of giant myofascial defect using synthetic prosthesis for patients with giant desmoid in abdominal wall is safe and effective.
