Abstract
PURPOSE Metachronous contralateral inguinal hernia (MCIH) may occur after unilateral inguinal hernia (IH) repair, potentially as a result of occult IH (OIH). Contralateral OIH can be checked for during laparoscopic transabdominal hernioplasty for the treatment of unilateral IH. This study aims to assess the efficacy of laparoscopic iliopubic tract repair (IPTR) in treating contralateral OIH to reduce MCIH. METHODS The medical charts of 3165 patients aged > 18 years who underwent laparoscopic transabdominal hernioplasty for unilateral IH from January 2013 to December 2021 were retrospectively reviewed. The patients were categorized into two groups based on contralateral OIH presence: negative OIH (nOIH, 2657 patients) and OIH (508 patients). In cases of OIH, IPTR was performed, involving suturing of the iliopubic tract and transversalis fascia arch. RESULTS MCIH was indirect in 26 and direct in 4 patients in the nOIH group, and was direct in 3 patients in the OIH group. The incidence of indirect MCIH was higher in the nOIH group than in the OIH (1.0% [n = 26/2657] vs. 0.0% [n = 0/508], p = 0.048). There was no difference in postoperative complication rates, pain scores, return to daily life, or duration of hospitalization between the nOIH and OIH groups. CONCLUSION Laparoscopic IPTR for OIH treatment is an effective method for reducing the risk of indirect MCIH.

Hernia 2023; 27:1467-1472. [PMID: 36795186 DOI: 10.1007/s10029-023-02754-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 02/03/2023] [Indexed: 02/17/2023]
Abstract
PURPOSE Occult hernias, hernias seen on radiologic imaging but not felt on physical exam, are common. Despite their high prevalence, little is known about the natural history of this finding. Our aim was to determine and report on the natural history of patients with occult hernias including the impact on abdominal wall quality of life (AW-QOL), need for surgery, and risk of acute incarceration/strangulation. METHODS This was a prospective cohort study of patients who underwent a computed tomography (CT) abdomen/pelvis scan from 2016 to 2018. Primary outcome was change in AW-QOL using the modified Activities Assessment Scale (mAAS), a hernia-specific, validated survey (1 = poor, 100 = perfect). Secondary outcomes included elective and emergent hernia repairs. RESULTS A total of 131 (65.8%) patients with occult hernias completed follow-up with a median (IQR) of 15.4 (22.5) months. Nearly half of these patients (42.8%) experienced a decrease in their AW-QOL, 26.0% were unchanged, and 31.3% reported improvement. One-fourth of patients (27.5%) underwent abdominal surgery during the study period: 9.9% were abdominal procedures without hernia repair, 16.0% involved elective hernia repairs, and 1.5% were emergent hernia repairs. AW-QOL improved for patients who underwent hernia repair (+ 11.2 ± 39.7, p = 0.043) while those who did not undergo hernia repair experienced no change in AW-QOL (- 3.0 ± 35.1). CONCLUSION When untreated, patients with occult hernias on average experience no change in their AW-QOL. However, many patients experience improvement in AW-QOL after hernia repair. Additionally, occult hernias have a small but real risk of incarceration requiring emergent repair. Further research is needed to develop tailored treatment strategies.

[PMID: 37010657 PMCID: PMC10533595 DOI: 10.1007/s10029-023-02785-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 03/24/2023] [Indexed: 04/04/2023]
Abstract
PURPOSE Laparoscopic herniorrhaphy (LH) has become the treatment of choice in many centers for patients with inguinal hernia (IH). Our aim was to compare the morbidity outcomes of bilateral vs unilateral IH repair using the laparoscopic total extra-peritoneal (TEP) technique, to determine whether undertaking bilateral IH repair places patients at additional risk. METHODS Manuscripts published up to the end of 2021 on PubMed/MEDLINE, EMBASE, Cochrane Library, Scopus, and Web of Science were searched. Patients (> 16 years) undergoing a primary elective unilateral or bilateral TEP operation, using the standard 3-port laparoscopic technique, were identified. Quality of evidence was assessed using the GRADE criteria. Meta-analysis was conducted where possible. Where this was not possible, vote counting was conducted using effect direction plots. RESULTS Eight observational studies, with a total of 18,153 patients were included. Operative time was significantly longer for bilateral operations. There was no significant difference in conversion to open, post-operative seroma, urinary retention, haematoma, and length of hospital stay. There was an increased rate of hernia recurrence in patients undergoing bilateral IH repair. CONCLUSION Although limited by the observational nature of the included studies, there is no conclusive evidence to suggest a differential burden of morbidity between unilateral and bilateral TEP IH repair. As all included papers are from observational studies only, evidence from all outcomes is at best very low quality. This manuscript thereby highlights a need for randomized controlled trials to be conducted in this area.

Laparoscopic Totally Extraperitoneal (TEP) Groin Hernia Repair in Patients After Contralateral TEP Groin Hernia Repair. SURGICAL LAPAROSCOPY, ENDOSCOPY & PERCUTANEOUS TECHNIQUES 2021; 32:79-83. [PMID: 34570075 DOI: 10.1097/sle.0000000000001006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 08/24/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND The totally extraperitoneal (TEP) repair for groin hernia is considered difficult in patients with a healed surgical scar in the lower abdomen. We reported the feasibility of repair in those patients and found that the most frequent previous procedure in patients for whom the procedure was changed intraoperatively was a contralateral TEP after TEP repair. We now report an expanded patient cohort with a suggested unified treatment strategy. MATERIALS AND METHODS From 2006 to 2020, 443 patients underwent laparoscopic TEP groin hernia repair. A contralateral TEP after TEP repair was performed in 35 patients. The conversion rate after TEP was compared with that after other operations. Patients were divided into completed contralateral TEP after TEP repair (N=28) and changed procedure groups (N=7). Clinical characteristics were compared including age, body mass index, location and type of hernia, and interval after previous surgery. Multivariate analysis was performed to evaluate risk factors for conversion of the TEP procedure. RESULTS Patients undergoing contralateral TEP after TEP repair were significantly overrepresented among patients for whom the procedure was changed compared with other previous operations (P<0.01), with an odds ratio of 19.91. Comparing completed TEP after TEP repair and changed procedure groups, there were no significant differences regarding age (mean: 67 vs. 69 y old), body mass index (22.4 vs. 22.5 kg/m2), type of hernia (indirect or direct), or duration after previous TEP repair (median: 642 vs. 470 d) and identified no significant risk factors. CONCLUSIONS The contralateral TEP after TEP repair for groin hernia is feasible. However, dense adhesions may be present if balloon dissection was performed at the previous TEP repair, and it is necessary to carefully dissect being ready to convert to other procedures such as TAPP repair or an anterior approach.

The Value of Preoperative Ultrasound in the Detection of Contralateral Occult Inguinal Hernia in the Treatment of Symptomatic Inguinal Hernia. SURGICAL LAPAROSCOPY, ENDOSCOPY & PERCUTANEOUS TECHNIQUES 2021; 32:35-40. [PMID: 34369480 DOI: 10.1097/sle.0000000000000987] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 06/04/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND The true incidence of contralateral occult inguinal hernia (OIH) is a debate. The repair of contralateral OIH in the treatment context of clinical symptomatic unilateral inguinal hernia (IH) is controversial. This study aimed to assess the effect and clinical benefit of preoperative ultrasound (US) in the diagnosis of contralateral OIH performed before surgery. METHODS The retrospective data of 155 consecutive male patients who underwent IH repair between January 2014 and January 2020 were analyzed. The surgical procedures for IH and the clinical outcomes of the US were evaluated. RESULTS Of 155 patients, 29 (18.7%) presented with bilateral IH. Preoperative US was performed in 73 cases of clinical unilateral IH (n=126), and 30 (23.8%) patients were found to have a contralateral OIH. The totally extrapreperitoneal (TEP) or Lichtenstein repair was conducted. Bilateral IH repair was proposed for all, but only 28 agreed and underwent bilateral repair. Patients with clinically bilateral hernia had more complications compared with patients diagnosed to have occult contralateral IH after the US (n=3 vs. n=0). In the overall group, the TEP procedure resulted in shorter hospital stay (P=0.001) and less pain (P=0.021). CONCLUSIONS The preoperative US may be recommended to assess the presence of a contralateral OIH as it is a noninvasive, radiation-free, widely available, relatively cheap diagnostic method. The preoperative US may change the surgical approach in up to 1/4 patients with a clinical unilateral IH. Either Lichtenstein repair or TEP repair can be performed with an acceptable complication rate in the case of OIH.

Contralateral exploration and repair of occult inguinal hernias during laparoscopic inguinal hernia repair: systematic review and Markov decision process. BJS Open 2020; 5:6045324.

Abstract
BACKGROUND Contralateral clinically occult hernias are frequently noted at the time of laparoscopic unilateral inguinal hernia repair. There is no consensus on the role of contralateral exploration and repair. This systematic review assessed the safety and efficacy of operative repair of occult contralateral inguinal hernias found during unilateral repair. METHODS PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched from inception to February 2020. Adults diagnosed with a unilateral inguinal hernia undergoing laparoscopic repair were included. The primary outcome was the incidence of occult contralateral hernias. Summative outcomes of operative and expectant management were reported along with development of a Markov decision process. RESULTS Thirteen studies (1 randomized trial, 12 observational cohorts) with 5000 patients were included. The incidence of occult contralateral inguinal hernias was 14.6 (range 7.3-50.1) per cent. Among patients who underwent repair, 10.5 (4.3-17.0) per cent experienced a postoperative complication. Of patients managed expectantly, 29 per cent later required elective repair for symptoms. Mean follow-up was 36 (range 2-218) months. Using a Markov decision process, it was calculated that, for every 1000 patients undergoing unilateral inguinal hernia repair, contralateral exploration would identify 150 patients with an occult hernia. Repair would result in 15 patients developing a postoperative complication and 105 undergoing unnecessary repair. Alternatively, expectant management would result in 45 patients requiring subsequent repair. CONCLUSION Contralateral repair is not warranted in patients with occult hernias diagnosed at the time of elective hernia repair. The evidence is largely based on observational studies at high risk of bias.

J Family Med Prim Care 2020; 9:2975-2979. [PMID: 32984158 PMCID: PMC7491803 DOI: 10.4103/jfmpc.jfmpc_207_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 03/13/2020] [Accepted: 03/23/2020] [Indexed: 02/05/2023] Open
Abstract
Background: The incidence of contralateral occult hernia (COH) varies from 4.2% to 57.5%. Total extraperitoneal (TEP) gives us opportunity to visualize contralateral groin for occult hernia and its simultaneous repair. Ultrasonography (USG) helps to diagnose occult hernia preoperatively with detection rate of 96.6% with specificity 84.4%. Objective: The aims of this study were to identify the incidence of contralateral occult inguinal hernia in clinically diagnosed unilateral inguinal hernia patients using USG as diagnostic modality and to compare the clinical outcomes of unilateral TEP vs. bilateral TEP with respect to pain, duration of hospital stay, time for return to normal work, and postoperative complications. Setting and Design: This was a prospective observational, single-center study. Materials and Methods: A total of 30 male patients were included in the study who was having clinically diagnosed unilateral hernia. All patients were assessed by USG for contralateral occult inguinal hernia. Results: Incidence of COH was 10%, two (6.7%) had indirect defect, and 1 (3.3%) had direct defect. Two (6.7%) patients underwent bilateral TEP and 28 (93.3%) underwent unilateral TEP. No significant difference was observed in terms of mean duration of hospital stay, duration of surgery, and visual analog scale score for pain in both unilateral and bilateral TEP. The mean for resuming daily work in unilateral TEP was 4.86 ± 0.833 days and in bilateral TEP the mean was 7.50 ± 0.70 days and this showed statistically significant difference (P < 0.001). Conclusion: Patients with COH should be counselled for synchronous repair as there is no significant difference in clinical outcomes of unilateral and bilateral TEP. On the basis of this pilot study, it can be concluded that preoperative USG is mandatory for diagnosis and simultaneous management of preexisting contralateral hernia.

Abstract
BACKGROUND With the widespread use of advanced imaging there is a need to quantify the prevalence and impact of hernias. We aimed to determine the prevalence of abdominal wall hernias among patients undergoing computed tomography (CT) scans and their impact on abdominal wall quality of life (AW-QOL). METHODS Patients undergoing elective CT abdomen/pelvis scans were enrolled. Standardized physical examinations were performed by surgeons blinded to the CT scan results. AW-QOL was measured through the modified Activities Assessment Scale. On this scale, 1 is poor AW-QOL, 100 is perfect, and a change of 7 is the minimum clinically important difference. Three surgeons reviewed the CT scans for the presence of ventral or groin hernias. The number of patients and the median AW-QOL scores were determined for three groups: no hernia, hernias only seen on imaging (occult hernias), and clinically apparent hernias. RESULTS A total of 246 patients were enrolled. Physical examination detected 62 (25.2%) patients with a hernia while CT scan revealed 107 (43.5%) with occult hernias. The median (interquartile range) AW-QOL of patients per group was no hernia = 84 (46), occult hernia = 77 (57), and clinically apparent hernia = 62 (55). CONCLUSIONS One-fourth of individuals undergoing CT abdomen/pelvis scans have a clinical hernia, whereas nearly half have an occult hernia. Compared with individuals with no hernias, patients with clinically apparent or occult hernias have a lower AW-QOL (by 22 and seven points, respectively). Further studies are needed to determine natural history of AW-QOL and best treatment strategies for patients with occult hernias.
