Major Complication Caused by Inguinal Hernia Recurrence After Percutaneous Internal Ring Suturing Procedure in a Patient With Loeys-Dietz Syndrome: A Case Report.

Inguinal hernia repair is one of the most frequently performed procedures in pediatric surgery. Treatment methods include classical open repair and laparoscopic approach. In this report we analyze a case of a 14-month-old boy with Loeys-Dietz syndrome treated for an inguinal hernia with laparoscopic percutaneous internal ring suturing (PIRS). Two weeks post-operatively the patient was diagnosed with a recurrence of the hernia complicated by an intestine strangulation. As a re-operation of the hernia, the Lichtenstein method was applied successfully. We analyzed the literature to determine the safety and possible contradictions of the PIRS procedure, with particular emphasis on patients with comorbidities such as connective tissue disorders. We conclude that in the PIRS procedure, despite its safety, feasibility and low complication rate in healthy patients, too few studies were made to draw similar conclusions for patients with comorbidities such as connective tissue disorders.

An Amyand Hernia With Concurrent Appendicitis Secondary to a Neuroendocrine Neoplasm: A Case Report.

Amyand's hernia (AH) describes the rare instance of a vermiform appendix within an inguinal hernia. Primary appendiceal neoplasms are also rare with the majority of cases being found incidentally during routine histopathology. This case reports the management of a 15-year-old male, who presented to the emergency department with acute appendicitis located within an indirect right inguinal hernia, which was ultimately secondary to a neuroendocrine tumor (NET) with serosal involvement. Intraoperative findings included macroscopic appendicitis with no evidence of perforation. Histopathology returned as a neuroendocrine tumor (pT4) with involved proximal margin and curative treatment was undertaken with a caecectomy which returned no residual malignancy. Key considerations include management options of peritoneal spread within the inguinal canal and recommended management NET in the context of an AH. It is important to understand the varied presentations of common surgical diagnosis such as appendicitis and underlying malignancy should always be considered a differential.

Omental fibroma combined with right indirect inguinal hernia masquerades as a scrotal tumor: A case report.

BACKGROUND: The most common causes of scrotal enlargement in patients include primary tumor of the scrotum, inflammation, hydrocele of the tunica vaginalis, and indirect inguinal hernia; scrotal enlargement caused by external tumors of the scrotum is rare. The patient had both a greater omentum tumor and an inguinal hernia, and the tumor protruded into the scrotum through the hernia sac, which is even rarer. Moreover, omental tumors are mostly metastatic, and primary omental fibroma is rare. CASE SUMMARY: Here, we report a rare case of a 25-year-old young man with scrotal enlargement and pain for 3 months. Preoperative examination and multidisciplinary discussions considered intra-abdominal tumor displacement and inguinal hernia, and intraoperative exploration confirmed that the greater omentum tumor protruded into the scrotum. Therefore, tumor resection and tension-free inguinal hernia repair were performed. The final diagnosis was benign fibroma of the greater omentum accompanied by an indirect inguinal hernia. CONCLUSION: This unusual presentation of a common inguinal hernia disease illustrates the necessity of performing detailed history taking, physical examination, and imaging before surgery.

The effect of internal orifice narrowing in laparoscopic inguinoscrotal hernia repair to prevent seroma formation: a prospective double-blind randomized controlled trial.

OBJECTIVES: Seroma represents the most prevalent postoperative complication following laparoscopic inguinal hernia repair, particularly in the case of large inguinoscrotal hernias. This randomized controlled trial was undertaken with the objective of assessing the effects of internal orifice narrowing achieved by suturing the divided distal hernia sac in laparoscopic repair of indirect inguinoscrotal hernias. METHODS: A total of 58 patients aged 18 years or older, were randomized into two groups: Group I, which underwent internal orifice narrowing, and Group II, which served as the control without narrowing. The study's primary endpoint was the incidence and volume of seroma in the inguinal region on postoperative days 1 and 7, as well as at 1, 3, and 6 months following the procedure. Secondary outcomes encompassed metrics like total operative time, acute and chronic pain levels, duration of hospital stay, recurrence rates, and the occurrence of any additional complications. RESULTS: In comparison to the control group, the experimental group exhibited a significantly lower incidence of seroma formation at 7 days (P = 0.001). Furthermore, the ultrasonic assessment indicated a reduced seroma volume in the operative group on postoperative day 7 (8.84 ± 17.71 vs. 52.39 ± 70.78 mL; P < 0.001). Acute pain levels and hospital stay were similar between the two groups (1.22 ± 0.76 vs. 1.04 ± 0.53, P = 0.073; 1.22 ± 0.07 vs. 1.19 ± 0.08, P = 0.627, respectively). Notably, neither chronic pain nor early recurrence, nor any other postoperative complications were observed in either group throughout the follow-up period, which extended for at least 6 months (range: 6-18 months). CONCLUSION: In the context of laparoscopic inguinoscrotal hernia repair, the incidence and volume of seroma can be significantly reduced through the implementation of internal orifice narrowing achieved by suturing the divided distal hernia sac. And, this reduction in seroma formation was not associated elevation in postoperative pain levels or recurrence rates.

Single-Incision Laparoscopic Percutaneous Extraperitoneal Surgery for the Treatment of Incarcerated Indirect Inguinal Hernia in Children.

Background: The aim of this study was to examine the feasibility and safety of the single-incision laparoscopic percutaneous extraperitoneal surgery for the treatment of incarcerated indirect inguinal hernia in children. Methods: Seventy-five patients who presented with incarcerated indirect inguinal hernia and underwent laparoscopic surgery from January 2019 to January 2022 in Children's Hospital, Zhejiang University School of Medicine were retrospectively analyzed. The data were collected including the clinical information of the patients, perioperative details, and postoperative outcomes. Results: The median age of these patients was 21 months with a median weight of 9 kg. Among these 75 patients, the herniated contents of 73 patients were pushed back successfully with external manual pressure under the monitoring of laparoscope, then we did the hernia sac high ligation by using fascial closure device. After successful reduction, three cases developed incarcerated intestine necrosis, we enlarged the umbilical incision, dragged out the necrotic intestine, and did parallel resection and anastomosis. Only in two patients, it was difficult to push back the herniated organ; therefore, these patients were converted to traditional open surgery. The average length of postoperative hospital stay for the patients who didn't get incarcerated organ necrosis was 2 days. All patients recovered very well; there was no recurrence of the hernia and any other postoperative complications. Conclusions: Single-incision percutaneous extraperitoneal laparoscopic surgery for the treatment of incarcerated indirect inguinal hernia in children appears to be safe and feasible. Our experience shows that it is recommended to perform laparoscopic surgery for incarcerated indirect inguinal hernia in children.

Clinical application of the modified neck-shoulder technique based on membrane autopsy to laparoscopic totally extraperitoneal prosthesis for indirect inguinal hernia.

OBJECTIVE: To investigate the anatomical basis and clinical application value of the modified neck-shoulder technique based on membrane autopsy in laparoscopic totally extraperitoneal prosthesis (TEP) for tension-free repairs of indirect inguinal hernia. METHODS: In this retrospective cohort study, we analyzed the clinical data of 136 patients with indirect inguinal hernia who underwent laparoscopic TEP for tension-free repairs at the Department of Gastroenterological Surgery Unit 1, the First Hospital of Putian City, Fujian Province from June 2017 to June 2020. The patients were divided into the modified neck-shoulder technique group (68 cases) and the traditional surgery group (68 cases), according to the different surgical methods. The intraoperative and postoperative conditions of the two groups were compared. RESULTS: Both the modified neck-shoulder technique group and the traditional surgery group completed the herniorrhaphy. Compared with the traditional surgery group, the modified neck-shoulder technique group had a shorter operation time [(37.15 ± 5.320) min vs. (54.04 ± 5.202) min, t = 18.472, p < 0.001], less intraoperative blood loss [(5.53 ± 1.634) ml vs. (16.21 ± 3.375) ml, t = 23.544, p < 0.001], lower incidence of intraoperative peritoneal injury [3 cases (4.41%) vs. 9 cases (13.26%), χ2 = 3.29, p = 0.07], lower intraoperative conversion rate [1 case (1.47%) vs. 8 cases (11.76%), χ2 = 5.83, p = 0.016], and lower incidence of postoperative chronic pain [1 case (1.47%) vs. 12 cases (17.65%), χ2 = 10.291, p = 0.001], all of which were statistically significant (p < 0.05). Both groups were followed up for 12 months after surgery. Relapse was not observed in any case. CONCLUSION: Drawing upon the surgical principles of the open neck-shoulder technique and the understanding of the membrane autopsy in the inguinal region, our center has summarized a set of operation procedures called the "modified neck-shoulder technique" for laparoscopic TEP in the tension-free repairs of indirect inguinal hernias. This new surgical technique could expeditiously and precisely navigate the interlayer gap in the preperitoneal space under the enlarged view of the laparoscope. It facilitated the high ligation, disconnection, or repositioning of the hernia sac, enhancing the reliability of patch placement while minimizing collateral damage, reducing postoperative complications, and shortening operation time.

Clinical efficacy of laparoscopic closed hernia ring combined with a patch repair for Gilbert type III indirect inguinal hernia.

Purpose: The incidence of seroma and postoperative pain after Gilbert type III inguinal hernia repair is high. To reduce postoperative complications, this study investigated the clinical efficacy of laparoscopic closed hernia ring combined with a patch repair for Gilbert type III indirect inguinal hernia. Methods: Through a prospective randomized controlled study, a total of 193 patients with Gilbert type III indirect inguinal hernia admitted to Nanchong Central Hospital affiliated with Chuanbei Medical College from May 2020 to December 2021 were selected and randomly divided into the inner ring closed group (85 patients) and the inner ring non-closed group (95 patients). The patients in both groups underwent laparoscopic tension-free repair of their inguinal hernias. General information such as operative time, postoperative hospital stay, and hospital cost were compared between the two groups, and the patients were followed up at 1, 7, 14, 21, and 28 days and then 3, 6, and 12 months after surgery to compare complications such as incidence of seroma, volume of the seroma fluid, incidence of pain, and visual analogue scale (VAS) pain score. Results: There was no conversion to open procedures in any of the patients. The operation time of the closed group was significantly longer than that of the non-closed group (64.2 ± 12.2 vs. 55.3 ± 9.5 min, P < 0.01). The proportion of patients with postoperative pain in the two groups was 39 (46%) vs. 59 (62%), P = 0.029 on 7 days; 17 (20%) vs. 33 (35%), P = 0.028 on 14 days; and 6 (7%) vs. 22 (23%), P = 0.003 on 21 days in the postoperative closed group and was significantly lower than that in the non-closed group, while we found that the non-closed group had a higher VAS pain score than that of the closed group (2.36 ± 0.61 vs. 1.95 ± 0.71, P = 0.003 on 7 days and 2.12 ± 0.49 vs. 1.65 ± 0.49, P = 0.002 on 14 days) after surgery according to the statistical results of the VAS pain score. The incidence of postoperative seroma and the amount of seroma fluid decreased gradually in both groups, but when comparing the two groups, the proportion of cases of seroma in the closed group on 7 days [45 (53%) vs. 79 (83%), P < 0.01]; 14 days [23 (27%) vs. 43 (45%), P = 0.011]; and 21 days [10 (12%) vs. 29 (31%), P = 0.002] after the operation were significantly less than that in the non-closed group. For the comparison of the amount of seroma fluid between the groups, the seroma fluid volume in the non-closed group was greater than that in the closed group (34.48 ± 20.40 vs. 43.87 ± 16.40 ml, P = 0.006, 7 days) and (21.79 ± 8.42 vs. 30.74 ± 10.39 ml, P = 0.002, 14 days) after surgery. There were no differences in the length of stay, total hospital costs, or postoperative complications (urinary retention, intestinal obstruction, nausea, vomiting, bleeding, and infection) between the two groups, and the differences were not statistically significant (P > 0.05). The postoperative follow-up period was 3-20 months, and no chronic pain or recurrence occurred during the postoperative follow-up period in either group. Conclusions: Closure of the hernia ring is safe and effective for laparoscopic hernia repair for Gilbert type III inguinal hernia, and it significantly reduces the incidence of postoperative seroma and further reduces the postoperative pain without increasing the risk of postoperative infection and recurrence.

Influence of the hernia sac treatment method on the occurrence of seroma after laparoscopic transabdominal preperitoneal hernia repair.

PURPOSE: To determine whether transection of the hernia sac during laparoscopic transabdominal preperitoneal hernia repair (TAPP) affects the occurrence of seroma, and to explore the risk factors for seroma. METHODS: In total, 330 consecutive male patients with indirect inguinal hernia who underwent TAPP repair at the Qingdao University Affiliated Hospital from January 2020 to June 2021 were retrospectively enrolled in this study. According to the intraoperative hernia sac treatment, patients were divided into a completely reduced sac group and a transected sac group. RESULTS: Among the 330 inguinal hernia male patients, 240 received hernia sac reduction and 90 received hernia sac transection. Fifty-four patients developed seroma, with an incidence of 16.4%. In patients with a hernia defect measuring ≥3 cm and extension into the scrotum, the difference in the incidence of seroma between the two treatment groups approached significance (P = 0.052). The risk factors for seroma, high body mass index, hernia sac ≥3 cm, extension of the hernia into the scrotum and operation time were significantly associated with postoperative seroma. CONCLUSION: This study showed that the incidence of seroma after TAPP was as high as 16.4%. For patients with a hernia sac that is too large and descended extends into the scrotum, transection may be better than complete dissection of the hernia sac and preventive measures should be taken for patients with high body mass index, hernia sac measuring ≥3 cm, and a high risk of the hernia extending into the scrotum.

Effects of intraoperative fixation of residual hernia sac on postoperative seroma in laparoscopic transabdominal preperitoneal inguinal hernia repair: a prospective randomized controlled trial.

The study was aimed to evaluate a prospective randomized controlled trial (RCT) In laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP), whether fixation of the residual sac after transecting the hernia sac can reduce the severity of postoperative seroma. A total of 252 male patients with a primary unilateral indirect inguinal hernia who underwent TAPP from September 2018 to November 2022 were recruited. Patients were randomized to the control group (CG)and the experimental group (EG). In the experimental group, after the hernia sac was transected, the residual sac was fixed to the lower edge of the rectus abdominis, while it was left in the preperitoneal space in the control group. Close follow-up was arranged to observe the incidence of seroma and other postoperative complications. All 214 patients were discharged successfully. 106 patients were randomly assigned to the control group, and 108 patients were assigned to the experimental group. There was no significant difference in the incidence of postoperative fluid extraction between the experimental group and the control group (11.1% VS.10.4%, p = 0.862), but the patients with seroma after the operation had fewer repeated extraction (0% VS. 45.5%, P = 0.033). The incidences of other postoperative complications were comparable in the two groups. In the treatment of indirect inguinal hernia with TAPP, after transecting the hernia sac, suturing and fixing the residual sac to the inferior edge of the rectus abdominis can reduce the incidence of repeated aspiration.

Novel modification of Marcy operation for indirect inguinal hernia reconstituting deep inguinal ring shutter action.

PURPOSE: The two most frequent and significant complications after inguinal hernia repair are hernia recurrence and post-herniorrhaphy chronic pain. To add anatomic and physiologic strength to the tissue repair, especially in indirect inguinal herniorrhaphy, we devised a modification of Marcy operation that can reconstitute inguinal shutter action more efficiently by changing the direction of the sutures vertical to horizontal. METHODS: During 36 months from 1st Jan. 2019, 148cases of 140 patients were operated for Indirect inguinal hernia or Pantaloon hernia (11 cases). 145 indirect inguinal herniorrhaphy were performed exclusively with author's modification of Marcy operation. Hernia recurrence during the follow-up period (3 months-36 months), and postoperative chronic pain at 3 months after herniorrhaphy were analyzed. RESULTS: 104 cases among the 145 indirect inguinal hernia (71.7%) were operated with only deep inguinal ring (DIR) reconstruction as author modified. In 41 cases (28.3%), posterior wall reconstruction was done simultaneously. There was no recurrence or reoperation case during the follow-up period. The incidence of postoperative chronic pain at postoperative 3 months of VAS greater than 3.0 was 2.2% (3 cases). CONCLUSIONS: Author's modification of Marcy operation was feasible anatomically in all indirect inguinal hernia repair, which is theoretically superior to classic Marcy operation in that repositioning the DIR more laterally and securing the obliquity and shutter action of the DIR. Result is at least not inferior in the aspect of short-term recurrence and chronic post-herniorrhaphy pain.

Combined pantaloon and femoral hernia: a common pathology in medicine occurring simultaneously.

Inguinal hernias are typically classified based on their location and can be divided into two types. The most commonly seen inguinal hernias are direct and indirect, which can both potentially require surgical intervention. When both types of hernias are seen simultaneously, it is classified as a pantaloon hernia. This case describes an instance of a femoral hernia being found along with a pantaloon hernia. We present a case of what was projected to be a common inguinal hernia repair but progressed to a rare presentation of a femoral hernia superimposed on a pantaloon hernia. Pantaloon hernias plus a femoral hernia is a rare defect that does not present as often as the different types of isolated hernias.

Large Incarcerated Inguinal Hernia: A Case Report.

A 90-year-old white male cadaver was found to have an incarcerated left inguinal hernia (IH). Although IHs are a very common pathology, the size and extent of this IH make it a unique case study. Upon gross dissection of the abdominal and pelvic cavities, 79 cm of small and large bowel was removed from the scrotal sac. The extent of the herniation had enlarged the scrotal sac to over 14 cm in both height and width and over 10 cm in depth. The herniation also caused the penis to become buried in the skin and not visible.

Pediatric ovarian sliding inguinal hernia, is surgical repair urgent?

OBJECTIVES: To find if repairing sliding inguinal hernias containing the ovary should be carried out urgently or not. METHODS: A retrospective chart review carried out at King Abdulaziz Medical City, Riyadh, Saudi Arabia from 2015-2022. All cases with an ovarian inguinal hernia in females aged 0-14 years were reviewed after obtaining approval from the Institutional Review Board. RESULTS: Female children with inguinal hernia patients were 191. A total of 28 cases were sliding inguinal hernias involving the ovary. All were repaired electively except for 4 cases that had an initial presentation of an incarcerated ovary at age less than 90 days which required urgent reduction and repair. CONCLUSION: Based on our review, ovarian sliding hernias in female patients can be repaired electively, although newborns are at a higher risk of complications from sliding inguinal hernias.

Surgical repair of indirect inguinal hernia in bonnet macaque (Macaca radiata).

Background: Hernia is a protrusion of an organ from the wall of the cavity bearing it. Omentum, adipose tissue, and intestinal loops are the most frequently involved organs. The present case report is a rare case of indirect inguinal hernia having omentum engaged in scrotum through hernial ring in a bonnet macaque (Macaca radiata) and its surgical management. Case Description: A 19-year-old male bonnet macaque was presented with distension of the right inguinal and scrotal region. Physical examination revealed an inguinal hernia. Surgical intervention was deemed necessary considering the state of the animal. The herniation was surgically corrected by the removal of the protruded fatty mass. The monkey was kept in strict confinement till complete healing. The animal recovered uneventfully in 2 weeks without any post-operative complications. This case report details a successful surgical repair of an indirect inguinal hernia in a bonnet macaque. Conclusion: Based on the present case study, it is concluded that surgery can be an ideal and effective option for the treatment of inguinal hernias in primates.

Can Percutaneous Internal Ring Suturing Procedure Take the Place of Open Method in the Surgical Treatment of Girls with Inguinal Hernia?

Objectives: Percutaneous internal ring suturing (PIRS) method for inguinal hernia (IH) repair in girls is increasingly used in clinics especially experienced in minimal invasive surgery. We aimed to evaluate and compare our results of laparoscopic PIRS and the open procedure for IH repair in girls in our series. Methods: We retrospectively evaluated female patients in our pediatric surgery clinic who underwent IH surgery between 2012 and 2017 and results were assessed statistically. Results: We identified 293 girls operated in our clinic with IH. In 164 of them, PIRS procedure (group 1) was performed; 73 had right, 26 had left, and 65 (39.6%) had bilateral IH. Among these 65 patients, 16 had only right and 11 had only left IH according to preoperative examination, which turned out to be bilateral during laparoscopy. In the open surgery group (Group II), there were 129 patients. Seventy-eight patients had right, 38 had left, and 13 (10%) had bilateral IH. Sliding fallo-pian tubes were present in seven of Group I versus 21 of group II (p<0.001), while sliding ovaries were present in seven of Group I versus 16 of Group II (p=0.015). Recurrence was observed in only one patient in Group I (p>0.05). Conclusion: The higher rate of bilaterality is still the problem for laparoscopic procedures. Despite over-diagnosis, no more complications were not detected due to PIRS. High ratio of sliding tubes and ovaries can be due to traction for preparing the sac in open surgery. Hematoma can be a serious problem to complete PIRS procedure. Preferred technique from the surgeon's point of view is in favor of PIRS procedure. In addition, PIRS pro-cedure can be more protective for internal genitalia, but more studies with higher numbers and longer follow-up period are needed.

Application of Noncontact Laparoscopic High Ligation of the Hernia Sac of the Vas Deferens in Children with Indirect Inguinal Hernia.

Objective: This study aims to evaluate the usefulness of vas deferens noncontact laparoscopic high ligation of the hernia sac in children with indirect inguinal hernia (IIH). Materials and Methods: The clinical data of 146 male children with IIH treated in the Anhui Children's Hospital from January 2018 to June 2019 were analyzed retrospectively. There were 82 patients in the observation group in which the inner ring opening was sutured and closed using the vas deferens noncontact suture and 64 patients in the control group in which the peritoneum at the inner ring opening was closed using the intradermal suture. The operation time, surgical complications, postoperative complications, and recurrence rate were compared between the two groups (followed up for 2 years). Results: The operation was successful in all the patients in both groups. In the observation group, there was one case of intraoperative spermatic cord vascular injury and one case of infra-abdominal wall vascular injury, and no intraoperative complications occurred in the control group. The operation time was 12.8 ± 1.4 minutes in the control group and 10.4 ± 2.6 minutes in the observation group (P < .01). The two groups of patients were followed up for 2 years, and no complications and no recurrence occurred. Conclusion: The vas deferens noncontact laparoscopic high ligation of the hernia sac to close the inner ring opening has several advantages: The operation is simple; the operation time is shorter than the traditional method, avoiding the possibility of vas deferens injury; and it is a safe, reliable, and effective surgical method. However, due to the small number of clinical cases in this study, its long-term effect requires further observation.

Factors associated with TNF-alpha levels in patients with indirect inguinal hernia: A cross-sectional study.

Introduction: Risk factors associated with inguinal hernia include a patent processus vaginalis due to an obliteration failure, defects in the transversalis fascia, increased intra-abdominal pressure, smoking, malnutrition, genetic factors, connective tissue defects and impaired collagen metabolism. Type I collagen predominates in the fascia, which plays a key role in the development of an inguinal hernia. Molecularly, the production of abnormal matrix components or increased inflammatory mediators in collagen such as TNF-α has a very important role in the occurrence of inflammation in inguinal hernias. The study aimed to determine the factors associated with TNF-alpha levels in patients with indirect inguinal hernias. Methods: We evaluate the effect of TNF-α on the anterior rectus sheath tissue collagen in 46 patients with indirect inguinal hernia using a cross-sectional study design. The ELISA method was used to evaluate the levels of collagen TNF-α. We used ANOVA, Pearson's correlation test, and Spearman's correlation test to determine which results were statistically significant, defined by a p-value < 0.05. Results: Body mass index (BMI) average results were 25.7 kg/m2. Mean clinical onset was 70.13 months across 46 samples. TNF-α levels and BMI were correlated (p = 0.009). The TNF-α levels in the clinical-grade group (p = 0.044) and the clinical onset group (p = 0.047) varied according to ANOVA. Conclusion: Clinical onset, BMI, clinical grade of indirect inguinal hernia, and TNF-α levels have a significant relationship.

Feasibility of laparoscopic indirect inguinal hernia repair with lateral umbilical fold covering internal inguinal ring combined with patch repair.

Introduction: For an indirect inguinal hernia (IIH), it is a challenge to repair the internal inguinal ring (IIR) with self-tissue reconstruction in laparoscopic repair. Aim: To evaluate the efficacy and safety of covering the IIR with the lateral umbilical fold (LUF) combined with patch repair in laparoscopic indirect inguinal hernia repair. Material and methods: Patients with IIH treated by trans-abdominal preperitoneal (TAPP) hernia repair at the Department of General Surgery, Shanghai Public Health Clinical Centre between September 2019 and March 2021 were retrospectively analyzed. In group I (n = 57) the LUF was overturned and sutured to cover the IIR under a laparoscope and subsequently repaired with a patch. In group II (n = 62), the IIR was not covered by the LUF but only repaired with a self-gripping mesh. Results: We noted a longer suture time in group I than in group II. Although the LUF was covered after suturing, no significant difference in postoperative pain was observed between the two groups. However, significant differences in surgery time and hospitalization cost (p < 0.05) were found. One case of recurrence was observed in group II. Conclusions: The LUF can be used in IIH to cover the IIR and is a feasible approach. The LUF covering the IIR has no significant difference in pain.

A randomised controlled study on the effects of hernial sac stump fenestration on ultrasound seroma prevention in laparoscopic Type III inguinal hernia repair.

BACKGROUND: The incidence of ultrasound seromas has significantly increased after large hernial sac surgery. Several methods are available for preventing ultrasound seromas, but the clinical results are poor. It has also been demonstrated that hernial sac stump fenestration during laparoscopic incisional hernia repair surgery can significantly decrease the incidence of ultrasound seromas. MATERIALS AND METHODS: Ninety patients aged 18-75 years who were treated in our hospital for primary Type III indirect inguinal hernia from March 2017 to March 2018 were randomised to a preventive fenestration group and a control group. All patients underwent transabdominal preperitoneal repair. The number of ultrasound seromas in the inguinal regions and ultrasound seroma volume on day 6 and months 1 and 3 after surgery in the two groups were compared. The secondary outcomes included length of surgery, urinary retention, acute pain, chronic pain, length of hospitalisation, recurrence rate and other complications. RESULTS: There were no significant differences in demographic characteristics. Ultrasound seroma incidence and ultrasound seroma volume on day 6 and months 1 and 3 after surgery were significantly lower in the preventive fenestration group than that in the control group. There were no significant differences in the length of hospitalisation or incidence of acute pain or urinary retention between the two groups. CONCLUSIONS: Hernial sac stump fenestration after hernial sac transection in inguinal hernia repair surgery is a simple method that can effectively reduce post-operative ultrasound seromas.
