Objective: To investigate the factors influencing small intestinal ischemia in elderly patients with incarcerated hernia. Methods: The clinical data of 105 elderly patients admitted for surgical procedures of incarcerated hernia at Department of General Surgery, Huadong Hospital between January 2014 and December 2021 were retrospectively analyzed. There were 60 males and 45 females, aged (86.1±4.3) years (range: 80 to 96 years). They were divided into normal group (n=55) and ischemic group (n=50) according to intraoperative intestinal canal condition. The t test, χ² test and Fisher's exact probability method were used for the univariate analysis of the factors that influence intestinal ischemia in patients, and Logistic regression was used for multifactorial analysis. Results: In all patients, 18 patients (17.1%) had irreversible intestinal ischemia with bowel resection. Six patients died within 30 days, 3 cases from severe abdominal infection, 2 cases from postoperative exacerbation of underlying cardiac disease, and 1 case from respiratory failure due to severe pulmonary infection. The results of the univariate analysis showed that there were differences in gender, history of intussusception, duration of previous hernia, white blood cell count, neutrophil percentage, C-reactive protein, type of incarcerated hernia, and preoperative intestinal obstruction between the two groups (all P<0.05). The Logistic regression results showed that the short time to the previous hernia (OR=0.892, 95%CI 0.872 to 0.962, P=0.003), high C-reactive protein (OR=1.022, 95%CI 1.007 to 1.037, P=0.003), non-indirect incarcerated hernia (OR=10.571, 95%CI 3.711 to 30.114, P<0.01) and preoperative intestinal obstruction (OR=6.438, 95%CI 1.762 to 23.522, P=0.005) were independent risk factors for the development of intestinal ischemia in elderly patients with incarcerated hernia. Conclusions: The short duration of the previous hernia, the high values of C-reactive proteins, the non-indirect incarcerated hernia, and the preoperative bowel obstruction are influencing factors for bowel ischemia in elderly patients with incarcerated hernia. A timely operation is necessary to reduce the incidence of intestinal necrosis and improve the prognosis.

Objective: To analyze the recurrence factors and reoperation effect of laparoscopic inguinal hernia repair. Methods: A total of 41 patients with recurrence after laparoscopic repair of the inguinal hernia admitted to the Department of Hernia and Abdominal Wall Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2017 to December 2021 were retrospectively analyzed. All patients were males, aging (62±7) years (range: 51 to 75 years). The recurrence intervals were 3 days to 7 years postoperatively. The surgical methods, causes of recurrence, and treatment outcomes of the patients were analyzed. Fisher exact probability method is used to compare the rates. Results: Among all cases, the primary surgical procedures included transabdominal preperitoneal herniorrhaphy (TAPP) in 31 cases and total extraperitoneal herniorrhaphy in 10 cases. The reoperative procedures included the TAPP of 11 cases and the Lichtenstein procedure of 30 cases. The factors of recurrent cases in all patients could be divided into 4 categories, including insufficient mesh coverage in 23 cases, mesh curling in 9 cases, mesh contractuture in 7 cases, and improper mesh fixation in 2 cases. Recurrence, infection, chronic pain, foreign body sensation didn't occur in the followed period of(M(IQR)) 18(24) months(range: 12 to 50 months). There was no statistical difference in the incidence of postoperative seroma between the TAPP and Lichtenstein procedure (3/11 vs. 20.0% (6/30), P=0.68). Conclusions: Postoperative recurrence of laparoscopic inguinal hernia is mostly caused by the lack of mesh coverage. Due to the emphasis on standardized surgical operation, a good outcome could be achieved through reoperation by the TAPP or Lichtenstein procedure.

Vasectomy damage is a common complication of open nonmesh hernia repair. This study was a retrospective analysis of the characteristics and possible causes of vas deferens injuries in patients exhibiting unilateral or bilateral vasal obstruction caused by open nonmesh inguinal herniorrhaphy. The site of the obstructed vas deferens was intraoperatively confirmed. Data, surgical methods, and patient outcomes were examined. The Anderson-Darling test was applied to test for Gaussian distribution of data. Fisher's exact test or Mann-Whitney U test and unpaired t-test were used for statistical analyses. The mean age at operation was 7.23 (standard deviation [s.d.]: 2.09) years and the mean obstructive interval was 17.72 (s.d.: 2.73) years. Crossed (n = 1) and inguinal ( n = 42) vasovasostomies were performed. The overall patency rate was 85.3% (29/34). Among the 43 enrolled patients (mean age: 24.95 [s.d.: 2.20] years), 73 sides of their inguinal regions were explored. The disconnected end of the vas deferens was found in the internal ring on 54 sides (74.0%), was found in the inguinal canal on 16 sides (21.9%), and was found in the pelvic cavity on 3 sides (4.1%). Location of the vas deferens injury did not significantly differ according to age at the time of hernia surgery ( ≥ 12 years or <12 years) or obstructive interval (≥15 years or <15 years). These results underscore that high ligation of the hernial sac warrants extra caution by surgeons during open nonmesh inguinal herniorrhaphy.

This study aimed to investigate the incidence of patent processus vaginalis (PPV) in pediatric patients with a unilateral nonpalpable testis and explore the associated factors. From May 2014 to April 2017, 152 boys who were diagnosed with a unilateral nonpalpable testis and underwent laparoscopy in Shanghai Children's Hospital (Shanghai, China) were included in this study. The data were collected and reviewed, and the results were analyzed regarding the age at operation, side, development, and position of the nonpalpable testis. The mean age of the patients was 2.6 (standard deviation: 2.3) years. The testis was absent in 14 cases, nonviable in 81 cases, and viable in 57 cases. The incidence of PPV was 37.5% (57 of 152) on the ipsilateral side and 16.4% (25 of 152) on the contralateral side. The ipsilateral PPV was more prevalent when the nonpalpable testis occurred on the right side ( P < 0.01). Besides, patients with a viable testis had a greater incidence of ipsilateral PPV than those with a nonviable or absent testis ( P < 0.01). Moreover, this rate was the highest when the testis was in the abdominal cavity and the lowest when the testis was in the scrotum (both P < 0.01). However, the incidence of contralateral PPV was independent of all the factors. In conclusion, in children with a nonpalpable testis, the incidence of an ipsilateral PPV was significantly related to the side, development, and position of the testis, while it was independent of these factors on the contralateral side.

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.

We investigated the associations of clinical and socioeconomic factors with delayed orchidopexy for cryptorchidism in China. A retrospective study was conducted on cryptorchid boys who underwent orchidopexy at Children's Hospital at Chongqing Medical University in China from January 2012 to December 2017. Of 2423 patients, 410 (16.9%) received timely repair by 18 months of age, beyond which surgery was considered delayed. Univariate analysis suggested that the laterality of cryptorchidism (P = 0.001), comorbidities including inguinal hernia/scrotal hydrocele (P < 0.001) or urinary tract disease (P = 0.016), and whether patients lived in a poverty county (P < 0.001) could influence whether orchidopexy was timely or delayed. Logistic regression analysis suggested that the following factors were associated with delayed repair: unilateral rather than bilateral cryptorchidism (odds ratio [OR] = 1.752, P < 0.001), absence of inguinal hernia or hydrocele (OR = 2.027, P = 0.019), absence of urinary tract disease (OR = 3.712, P < 0.001), and living in a poverty county (OR = 2.005, P < 0.001). The duration of postoperative hospital stay and hospital costs increased with the patient's age at the time of surgery.

Objective: To investigate the success rate and safety of percutaneous vasoseminal vesiculography with the disposable vasographic interventional therapy kit (VITK). METHODS: This study included ninety-six 19－65 (mean 43) years old male patients with infertility, hematospermia, seminal vesicle cyst, ejaculatory duct cyst, ejaculatory dysfunction, or vas deferens injury, with disease courses varying from 1 month to 7 years. With an open, multi-centered, single-group, self-controlled design and using the disposable VITK, we treated the patients by percutaneous vasoseminal vesiculography via injection of contrast medium into the vas deferens cavity under local anesthesia. RESULTS: Percutaneous vasoseminal vesiculography was successfully performed in 92 (97.87%) of the patients, which revealed abnormal seminal ducts in 51 cases (54.3%). Among the 28 infertile patients, 3 were found with bilateral and 5 with unilateral vas deferens obstruction. Vesiculitis was detected in 36 (81.8%) of the 44 hematospermia patients and bilateral vas deferens abnormality in 5 (38.5%) of the 13 patients with ejaculatory dysfunction. Transectional damage was observed in 2 patients with vas deferens injury induced by bilateral inguinal hernia repair. Three cases of seminal vesicle cyst and 4 cases of ejaculatory cyst were definitely diagnosed by vasoseminal vesiculography. CONCLUSIONS The disposable vasographic interventional therapy kit, with the advantages of simple operation and high safety, deserves a wide clinical application in vasoseminal vesiculography.

OBJECTIVETo explore the appropriate operative strategy in recurrent groin hernia repair.

METHODSClinical and follow-up data of 82 patients with recurrent groin hernia undergoing operation at Department of Pancreatobiliary Surgery, Xiangya Hospital of Central South University from April 2010 to April 2017 were analyzed retrospectively. The operative approaches included laparoscopic transabdominal preperitoneal (TAPP) hernia repair, Lichtenstein repair and hybrid repair. Surgical method selection was based on the basis of European Hernia Society guidelines, combined with hernia histories, preoperative examination results and intra-operative results: (1) When an anterior approach (Lichtenstein, Bassini or Shouldice surgery) was adopted in the previous operation, TAPP was preferred for the recurrent groin hernia. (2) When the previous operation was an posterior approach [TAPP or total extraperitoneal hernioplasty (TEP)], Lichtenstein method was preferred. Moreover, Lichtenstein surgery with local anesthesia or nerve block was also selected when the patient could not tolerate general anesthesia. (3) When extensive preperitoneal adhesions were found in patients with previous anterior approach repair during laparoscopic exploration, especially in patients who had relapsed after multiple operations or had previous biochemical glues injection, hybrid surgery was preferred.

RESULTSAll 82 patients completed operations smoothly. TAPP, Lichtenstein and hybrid operation were applied in 74, 4 and 4 patients, respectively, with median operative time of 70 minutes (40-130 minutes) in TAPP, 60 minutes (40-90 minutes) in Lichtenstein and 120 minutes (70-150 minutes) in hybrid operation, respectively. The median numerical rating scales (NRS) score was 2 (0-6) on postoperative day 1. The incidences of postoperative seroma, pain and urinary retention were 4.9% (4/82), 2.4% (2/82) and 1.2% (1/82) respectively. The median postoperative hospital stay was 2 days (1-6 days). Seventy-two patients were followed-up from 11 to 87 months. The median follow-up period was 27 months. The median inguinal pain questionnaire (IPQ) score was 2 (0-8) month after operation. One recurrent case was reported 1 year after operation. No incision or mesh infection and long-term inguinal chronic pain were observed.

CONCLUSIONSFor recurrent patients with previous open anterior approach, TEP and TAPP repair are equivalent surgical techniques, and the choice should be tailored to the surgeon's expertise. For those with previous TAPP or TEP repair, Lichtenstein technique is recommended. For those with adhesions both in anterior transverse fascia and pre-peritoneum, hybrid operation may be the preferable choice according to adhesion conditions.
