Inguinal hernia refers to an extraperitoneal hernia occurring in the inguinal region. The etiology of inguinal hernia is not completely clear, but is related to gender, age and family history. According to the anatomy of hernia, there are indirect hernia, direct hernia, femoral hernia, composite hernia and peripheral femoral hernia. According to the content of the hernia sac, it is divided into reducible hernia, irreducible hernia, incarcerated hernia and strangulated hernia. There are also several special types of hernia. Typical inguinal hernia can be diagnosed by medical history, symptoms and physical examination. If the diagnosis is unclear or difficult, the imaging examination can assist the establishment of diagnosis. Only through surgery, inguinal hernia in adult patients could heal. The following requirements should be fulfilled: (1)The surgeons need to acquire accreditation of medical residency and should have corresponding surgical training; (2)The qualification of laparoscopic surgeons require the completion of basic laparoscopic training and hernia fellowship training as well as passing relative examinations; (3)Training of hernia and abdominal wall surgeons should be completed in centers with corresponding qualifications; (4)Preoperative education should be provided to patients and/or their families, emphasizing the communication with patients before surgery and indicating the operation principle and measures, whether mesh should be used, and informed consent should be given. Hernia repair materials are mainly non-absorbable inert mesh. Surgery could be divided into two types: open and laparoscopic surgery, including tissue suture repair, repair with materials, total extraperitoneal repair (TEP) and trans-abdominal preperitoneal repair(TAPP), etc. Combined with the clinical practice in China,we completed the "Guideline for Diagnosis and Treatment of Adult Groin Hernia (2018 edition)" on the basis of the previous edition of the guideline. The relevant medical institutions and peers in China are requested to carry out this guideline according to actual clinical reference.

The present study compared the postoperative analgesic effects of ilioinguinal and iliohypogastric nerve block with infiltration of local anesthetics (bupivacaine) into the wound in children after inguinal hernia repair. Ninety children below 7 years old who were scheduled elective inguinal hernia repair were randomly allocated into one of three groups. The patients in nerve block (NB) group, ilioinguinal and iliohypogastric nerve block was done with 0.5 mL/kg of 0.25% bupivacaine. The patients in infiltration of local anesthetics (LI) group, 0.5 mL/kg of 0.25% bupivacaine was infiltrated into the wound after surgery. The patients in control group were allocated as a Control group. Postoperative pain was assessed at 1, 3, 5, and 24 hours after operation with FLACC scale and additional analgesic consumption were counted. The three groups were not significantly different in age, sex, body weight, and duration of operation. Pain scores at 1 hour and 3 hours after operation were significantly higher in Control group than in NB group and LI group (p<0.01), whereas there were no difference between NB group and LI group. The rescue analgesics administration was significantly higher in Control group (n=11) than in NB group (n=6) and LI group (n=7) (p<0.05). There were 2 cases of transient femoral nerve palsy in NB group. Both of ilioinguinal and iliohypogastric nerve block and infiltration of local anesthetics into the wound provided effective postoperative analgesia in early postoperative period following inguinal hernia repair in children. But no difference between the two methods. Technically, infiltration of local anesthetics into the wound was easier and safer than ilioinguinal and iliohypogastric nerve block.

PURPOSE: To compare the outcomes between laparoscopic total extraperitoneal (TEP) repair and prolene hernia system (PHS) repair for inguinal hernia. METHODS: A retrospective analysis of 237 patients scheduled for laparoscopic TEP or PHS repair of groin hernia from 2005 to 2009 was performed. RESULTS: The mean age was 52.3 years in TEP group and 55.7 years in PHS group. Of 119 TEP cases, 98 were indirect inguinal hernia, 15 direct type, 5 femoral hernia and 1 complex hernia; Of 118 PHS cases, 100 indirect, 18 direct type. All in TEP group were performed under general anesthesia and 64% of PHS group were performed under spinal or epidural anesthesia. Preoperatively, 10 cases of recurrent inguinal hernia were involved in our study (4 in TEP, 6 in PHS group). The mean operative time was similar in both groups (74.8 in TEP, 71.2 in PHS group), however mean hospital stay (1.6 days in TEP, 3.2 days in PHS group, P = 0.018) and mean usage of analgesics (0.54 times in TEP, 2.03 times in PHS group, P < 0.01), complications (36 cases in TEP, 6 cases in PHS group, P < 0.01) showed statistical differences. There is only 1 case of postoperative recurrence inguinal hernia in PHS group but it has no statistical significance (P = 0.314). CONCLUSION: Compared to PHS repair, laparoscopic TEP repair has some advantages; shorter hospital stay, less frequent need of analgesics; as well as more postoperative complications such as hematoma, seroma, scrotal swelling.

PURPOSE: Unlike males, inguinal hernia surgery in females is an uncommon surgical procedure. The efficacy of laparoscopic surgery for female hernia must be proven. This study compared the clinical characteristics of male and female hernia as well as the efficacy of laparoscopic surgery with that of open surgery in female hernia. METHODS: From March 2007 to February 2011, one surgeon (C.S.) at the authors' institution operated on 965 patients (male/female=884/81) who were each more than 19 years old. The female patients were divided into the laparoscopic (n=67, TEP/TAPP=66/1) and open surgery groups (n=14). RESULTS: The mean age of the female patients was lower than that of the male patients. The incidence of bilateral and direct hernia was higher in the male patients but the incidence of femoral hernia was higher in the female patients (0.6 vs. 8.6%, p<0.001). Among the 81 female patients, the mean age of the patients with femoral hernia was higher than that of the patients with other types of hernia (56.4+/-12.5/43.0+/-15.1, p<0.026). The operation times and pain scores of the two groups 7 days after surgery were comparable. CONCLUSION: The findings revealed a higher incidence of femoral hernia in the female patients than male patients. Patients with a femoral hernia were older than those with other types of hernia. Therefore, laparoscopic surgery must be considered for elderly female patients who have a high incidence of femoral hernia.

This case presents a rare complication of the spontaneous rupture of a femoral hernia in an elderly woman without causing much systemic effect despite the herniated bowel being necrosed and perforated, giving rise to an enterocutaneous fistula. The small bowel had also prolapsed through the fistula opening, making it a very rare and alarming presentation.

PURPOSE: The repair of groin hernias with local anesthesia has gained popularity. Two main methods have been described for local anesthesia. This study was aimed at comparing percutaneous truncular ilioinguinal-iliohypogastric block and step-by-step infiltration technique by using cadaver dissections. METHODS: The study was performed on an adult male cadaver by using blue dye injection. A percutaneous nerve block simulation was done on right side and the dye was given in between the internal oblique and transversus muscles. On the left side, a skin incision was deepened and the dye was injected under the external oblique aponeurosis. Following the injections, stained areas were investigated superficially and within the deeper tissues with dissection. RESULTS: There was a complete superficial staining covering the iliohypogastric and ilioinguinal nerves in the inguinal floor at both sides. On the right side, intraabdominal observation showed a wide and intense peritoneal staining, while almost no staining was seen on the left side. Preperitoneal dissection displayed a massive staining including testicular vascular pedicule and vas deferens on the right side. The dye solution also infiltrated the area of the femoral nerve prominently. On the contrary, a very limited staining was seen on the left. CONCLUSION: It may not always be easy to keep the percutaneous block within optimum anatomical limits without causing adverse events. A step-by-step infiltration technique under direct surgical vision seems to be safer than percutaneous inguinal block for patients undergoing inguinal hernia repair.

PURPOSE: Laparoscopic herniorrhaphy (LH) has an advantage for evaluating the viability of incarcerated bowel. In this retrospective study, we aimed to review the data for use of the TEP technique in treating incarcerated hernias in order to document the feasibility of the laparoscopic procedure. METHODS: During a 2-year period from January 2008 to December 2009, one surgeon (C.S) at our institution operated on 27 patients with acutely (n=3) or chronically (n=24) incarcerated hernia. Incarcerated hernias were divided into acute or chronic types arbitrarily, based on who had symptoms of acute abdominal pain and signs of intestinal obstruction. For acute cases, the TEP procedure was done following laparoscopic transperitoneal evaluation to assess viability of the incarcerated bowel. RESULTS: All patients except one having a femoral hernia were male. Mean age was 41 years old (range, 25~75). No case converted from a laparoscopic to an open procedure. Two acute incarcerated cases contained a segment of small bowel and the other contained small bowel and omentum. All acute cases were operated on successfully on an emergency basis by laparoscopic TEP repair. All chronic cases contained omentum without bowel. In one case of acute and seven cases of chronic type, a small inguinal incision was made to reduce hernia contents. No recurrence was noticed at a mean of 13 months of follow-up. CONCLUSION: If there is no entrapment of bowel in chronic incarcerated cases, the TEP procedure will be satisfactory. It may be reasonable, however, to evaluate viability of bowel transperitoneally before doing a TEP procedure in acute cases.

Saphena varix is very rare disease that characterized by isolated distention of the saphenous vein below the sapheno-femoral junction. Saphena varix must be differentiated from other medical problems that can cause a groin mass. A 49-year-old man presented with a palpable mass on the right upper thigh and he'd had the mass for 6 months. There was no history of trauma, and the mass was especially noticeable when he was standing. On the physical examination, a 5 cm-sized soft, nontender, compressible mass was detected at the right upper medial thigh near the femoral foramen. Doppler sonography showed a saccular venous dilatation of the great saphenous vein just below the saphenofemoral junction. On computed tomography, there were superficially dilated veins in the right thigh and calf, a focal saccular aneurysm at the proximal segment of the right greater saphenous vein and no evidence of deep vein thrombosis. Aneurymal excision and stripping of the greater saphenous vein were performed. No complication was observed at the 2 week follow-up.

PURPOSE: The aims of this study were to evaluate the efficacy of laparoscopic totally extraperitoneal (TEP) repair of femoral hernia. METHODS: Eight patients who underwent laparoscopic TEP repair for femoral hernia between 2008 and 2010 were reviewed retrospectively. In total, 256 adult patients underwent inguinal or femoral hernia repair; TEP was performed in 224 patients. The preoperative diagnosis, clinical symptom, operative finding, postoperative complications, chronic pain, and recurrence were analyzed. RESULTS: The incidence of femoral hernia was 8 (3.1%) in the present study. The female to male ratio was 3:1 (6 females and 2 males). Seven patients were preoperatively misdiagnosed with inguinal hernia using ultrasonography. Computed tomography (CT) was performed in three patients, and femoral hernia was diagnosed in two patients. Two patients had synchronous femoral hernia with direct or indirect inguinal hernia. One patient has previously undergone ipsilateral inguinal hernia repair. In all patients, the hernia sac was irreducible by gas insufflation. Seven patients had lipoma-like soft tissue in hernia sac. Peritoneal tears developed in three patients. There was one postoperative complication: chronic discomfort due to seroma. There was no recurrence during median 6.5 months (range 2~26). CONCLUSION: Laparoscopic TEP repair is safe and effective therapeutic option for repair of femoral hernia. CT images are the most valuable type for the evaluation of the femoral hernia.

PURPOSE: Misdiagnosis is frequent in femoral hernia as inguinal hernia. The aims of this study were to examine the diagnostic concordance and to define the factors having influence on the correct diagnosis of femoral hernia. METHODS: Thirty-two patients who underwent femoral hernia operations were analyzed retrospectively. RESULTS: The mean age of the study subjects was 65.8+/-15.5 (36~97) and the female to male ratio was 5.4:1. The mean body mass index (BMI) was 19.8 kg/m2 (14.6~26.9 kg/m2). Twelve patients (37.5%) showed pre- and post-operative diagnostic concordance and 20 patients (62.5%) did not. Among the 20 misdiagnosed cases, 16 cases were misdiagnosed as inguinal hernia, 2 cases as lipoma, and 1 case as lymphadenopathy. The factors related to the correct diagnosis of femoral hernias were associated with groin mass (96.9%, 31/32: 23 painless and 8 painful), size fluctuation of mass (cyclic wax and wane pattern) (84.4%, 27/32), long duration of mass (over 1 month) (75.0%, 24/32), femoral venous compression CT findings (63.6%, 14/22), and positive ultrasonographic findings (42.1%, 8/19). Emergency operation was done in 12 cases (37.5%). Incarceration was found in 23 cases (71.9%) and most of the incarcerated organs were omental fat (11 cases) and small bowel (10 cases). Bowel resection was done in 4 cases and 2 patients combined inguinal hernia. CONCLUSION: Through the careful taking of medical history and physical examination, physicians can achieve the correct diagnosis and can also decrease the frequency of emergency operations and their related complications.
