Uncovering a Rare Case of Hepatic Round Ligament Epigastric Hernia

Abdominal wall hernias are one of the most common surgical diseases present in both males and females nowadays. However, with only a few cases reported in the literature, hepatic round ligament hernias are a rare clinical manifestation. This case shows how a common symptom such as epigastric pain can be associated with this rare condition. In general, abdominal computed tomography (CT) images are the choice of study to evaluate complications and the involvement of different intestinal sections. Some laboratory tests can be performed to suspect intestinal ischemia secondary to strangulated hernias. Primary repair utilizing mesh is the preferred surgical treatment. This procedure can be performed through laparoscopic or open technique, depending on the surgeon's skills and patient preference.

Multiple Complicated Concurrent Hernias in a Single Patient: A Case Report

Multiple complicated concurrent hernias with obturator hernia and paraesophageal hernia unusually occur in clinical settings. The obturator hernias belong to a rare pelvic hernia that accounts for a minority of all abdominal hernias. Besides, paraesophageal hernias occur commonly in elderly female patients. Clinical manifestations of these hernias are usually unspecific and the diagnosis is based on computed tomography (CT). In this paper, we presented a case of multiple complicated hernias in an 81-year-old woman. She was admitted to our hospital due to intestinal obstruction that was caused by a simultaneous obturator and paraesophageal hernia. She was successfully treated by laparoscopic hernia repair. Postoperative progression was favorable. She was then discharged from the hospital after four hospital days.

Beyond the Common: A Case Report on Right Paraduodenal Hernia

Paraduodenal hernias, particularly those on the right side, are rare but clinically significant occurrences characterized by the abnormal protrusion of abdominal contents through mesenteric defects adjacent to the duodenum. These hernias result from embryologic malformations and can lead to complications such as intermittent abdominal pain, nausea, and, in severe cases, bowel obstruction. This case describes a 48-year-old male who presented with a 24-hour history of colicky abdominal pain in the right upper quadrant, associated with nausea. Further investigation, including a computed tomography scan, revealed a right paraduodenal hernia with herniation of small bowel loops through a mesenteric defect. Timely surgical intervention via laparoscopic exploration confirmed the diagnosis and facilitated the reduction of herniated bowel, followed by meticulous repair of the mesenteric defect using nonabsorbable sutures. The patient's recovery was uneventful, with a return to normal bowel function, and postoperative follow-up showed the resolution of symptoms. This case underscores the clinical complexity and management challenges associated with right paraduodenal hernias. Surgical intervention, guided by laparoscopic exploration, emerged as an effective and minimally invasive approach. The successful reduction of herniated small bowel loops and meticulous closure of the mesenteric defect contributed to a favorable postoperative course, highlighting the importance of timely intervention to prevent complications.

Outcomes of a Large Series of Laparoscopic Ventral Hernia Repairs after Liver Transplantation

BACKGROUND

The hernia defects that develop in liver transplant recipients tend to be complex. Unfortunately, there is a paucity of data to guide post-transplant hernia management. Our goal was to evaluate the outcomes following laparoscopic ventral hernia repair (LVHR) in liver transplant recipients.

METHODS

A retrospective review of a prospectively kept database of liver transplant patients at a single tertiary healthcare facility was completed. All patients between 2007 and 2020 who underwent LVHR for a hernia at their transplant incision site were included. The primary outcome studied was hernia recurrence. Secondary outcomes included time-to-hernia repair, complications, and length of stay (LOS).

RESULTS

There were 89 patients who met inclusion criteria. 82% were male, mean age was 60 years, and mean body mass index was 30.2 kg/m2. 94.4% were on tacrolimus and 36% on mycophenolate mofetil. Median time-to-hernia repair was 16 months with a mean mesh size of 743 cm2 and length of stay of 3.7 days. None required conversion to an open operation. Postoperative complications included ileus (20.2%), acute kidney injury (11.2%), pneumonia (6.7%), and bleeding requiring re-operation (1.1%). Hernia-related complications included chronic suture site pain (1.1%), seroma requiring intervention (3.3%), surgical site infection (3.3%), nonoperative mesh infection (1.1%), and mesh infection requiring explantation (1.1%). Median follow-up was 23 months. Hernia recurrence occurred in 4.5% and no predictive variables for recurrence were identified.

CONCLUSIONS

Although the hernia defects that develop in liver transplant recipients are complex and their comorbidities significant, LVHR can safely and effectively repair these defects with low rates of recurrence and complications.

Pre-peritoneal Plus Portal Infiltration Versus Bilateral Transversus Abdominis Plane Block in Laparoscopic Hernia Repair

Background and objective The role of the pre-peritoneal infiltration of local anesthetic (PILA) in laparoscopic hernia repair has been equivocal. Ultrasound-guided transversus abdominis plane (TAP) block has been extensively studied. However, studies comparing these two methods are very scarce. Hence, this study was undertaken to compare the efficacy of pre-peritoneal plus portal infiltration with TAP block in this population. Materials and methods This double-blinded randomized comparative study was conducted on a total of 32 patients by allotting 16 patients in each group. Group A patients were given pre-peritoneal plus portal infiltration of 15 mL of 0.5% ropivacaine for each technique by the operating surgeon, while Group B patients were administered bilateral TAP block with 0.5% ropivacaine, 15 mL on each side under ultrasound guidance by the anesthesiologist. Results The demographic variables and duration of surgery were comparable between the two groups. Also, the postoperative requirement of fentanyl between the two groups was insignificant. However, the duration of anesthesia was significantly longer in Group B attributing to the extra time taken for the administration of the TAP blocks. Conclusion Both ultrasound-guided TAP block and the PILA plus portal infiltration are effective techniques for pain relief after laparoscopic hernia repair. Either of these two techniques can be chosen depending on the availability of resources, expertise, etc.

Return to Work in Patients With Unilateral Inguinal Hernia Surgery: A Comparative Study Between Laparoscopic Transabdominal Preperitoneal Approach and Lichtenstein Tension-Free Mesh Repair

Objective The objective of this prospective cohort study was to compare the time to return to work between patients who underwent laparoscopic transabdominal preperitoneal (TAPP) hernia repair and those who underwent Lichtenstein tension-free hernia repair with mesh for unilateral inguinal hernia. Methodology Patients were registered for unilateral inguinal hernia review at Aga Khan University Hospital, Karachi, Pakistan, from May 2016 to April 2017 and followed till April 2020. All patients aged 16-65 planned for unilateral transabdominal preperitoneal hernia repair or Lichtenstein tension-free hernia mesh repair were included. Patients with bilateral inguinal hernia repair, limited activity, or above retirement age were excluded. A non-probability consecutive sampling technique was implemented, and patients were divided into two cohort groups: Group A underwent laparoscopic transabdominal preperitoneal hernia repair, while Group B underwent Lichtenstein tension-free mesh repair. Patients were followed up at one week to inquire about the resumption of activities and then at one and three years for recurrence. Results Sixty-four patients met the inclusion criteria; three patients opted out of research, and 61 patients agreed to participate; one patient was excluded due to the conversion of the procedure. The remaining 30 in Group A and 30 in Group B were followed for the study period. The mean time to return to work in Group A was 5.33 ± 4.46 days; in Group B, it was 6.83 ± 4.58 days, with a p-value of 0.657. One recurrence was observed at three years in Group A. Conclusion Although the time to return to work at our hospital was slightly shorter in laparoscopic hernia repair than in the open technique, the results were not statistically significant. In addition, there was no significant difference in hernia recurrence at the one-year follow-up between laparoscopic transabdominal preperitoneal hernia repair and Lichtenstein tension-free hernia mesh repair for unilateral inguinal hernia.

Peritoneal Bridging Versus Nonclosure in Laparoscopic Ventral Hernia Repair: A Randomized Controlled Trial

Introduction

Postoperative seroma and pain are common problems following laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernias. These adverse outcomes may be avoided by dissecting and using the peritoneum in the hernial sac to bridge the hernia defect.

Methods

This was a patient- and outcome assessor-blinded, parallel-design, randomized controlled trial comparing nonclosure and peritoneal bridging approaches in patients scheduled for elective midline ventral hernia repair. The primary endpoint was seroma volume on ultrasonography. The secondary endpoints were postoperative pain, recurrence, and complications.

Results

Between November 2018 and December 2020, 112 patients were randomized, of whom 60 were in the nonclosure group and 52 were in the peritoneal bridging group. The seroma volume in the nonclosure and peritoneal bridging groups were 17 cm3 (6-53 cm3) versus 0 cm3 (0-26 cm3) at 1-month follow-up (P = 0.013). The median volume was zero at the 3-, 6-, and 12-month follow-ups in both groups. No significant differences were observed in early postoperative pain (P = 0.447) and in recurrence rate (P = 0.684). There were 4 (7%) and 1 (2%) perioperative complications that lead to reoperations in simple IPOM (sIPOM) and IPOM with peritoneal bridging (IPOM-pb), respectively.

Conclusions

Seroma was less prevalent after IPOM-pb at 1-month follow-up compared with sIPOM, with similar postoperative pain 1 week after index surgery in both groups. At subsequent follow-ups, the differences in seroma were not statistically significant. Further studies are required to confirm these results. Trial registration (NCT04229940).

Collateral damage of wandering ProTacks

CASE

A 75-year-old man presented with mixed obstructive and storage lower urinary tract symptoms (LUTS). He had undergone transurethral resection of the prostate (TURP) 5 years and laparoscopic inguinal hernia repair 20 years ago. He had a stone adherent to the bladder wall and an occlusive prostate.

OUTCOME

He underwent a re-do TURP and stone removal. Stone removal revealed an underlying metal coil straddling the bladder wall, which had served as a nidus for stone formation. The metal ring was a ProTack staple from previous hernia surgery, which had detached and wandered into the bladder. At follow-up after 12 weeks, the patient was asymptomatic, and his urine was sterile. Therefore, he chose to be treated conservatively for the ProTack and was started on periodic follow-up and cystoscopic surveillance. Shortly after review, he developed intestinal obstruction, which resolved spontaneously and was thought to be secondary to adhesions from other tacks that had migrated into the peritoneal cavity.

CONCLUSION

We have reported a case of a ProTack from a previous hernia repair migrating into the bladder and also causing intestinal obstruction. The case is very rare because of the combination of complications. Clinicians should beware of delayed complications and damage to other organs due to metallic hernia staples.

Small Bowel Does Not Belong in the Pericardium: Case of a Traumatic Intrapericardial Diaphragmatic Hernia

Intrapericardial diaphragmatic hernia (IPDH) is rare and most often a sequela of blunt thoracic trauma. The trans-abdominal or thoracic repair approaches are based on the acuteness of presentation and the expectation of encountering intrapericardial adhesions. We present an acute IPDH in an 80-year-old female patient managed with a laparoscopic trans-abdominal repair. Misdiagnosis and complications from the delayed presentation can be avoided with careful attention to the initial exam, imaging, and early operative repair if the patient is a candidate for the trans-abdominal approach.

Abdominal Wall Block Decreases Intraoperative Opioid Con-Sumption by Surgical Pleth Index-Guided Remifentanil Administration in Single-Port Laparoscopic Herniorrhaphy: A Prospective Randomized Controlled Trial

Abdominal wall blocks (AWBs) can reduce pain during surgery and lessen opioid demand. Since it is difficult to know the exact level of intraoperative pain, it is not known how much the opioid dose should be reduced. In this study, using the surgical pleth index (SPI), which indicates pain index from sympathetic fibers, the amount of remifentanil consumption was investigated. We conducted single-port laparoscopic hernia repair in 64 patients, as follows: the regional block group (R group) was treated with AWB, while the control group (C group) was only subjected to general anesthesia. In both groups, the remifentanil concentration was adjusted to maintain the SPI score between 30 and 40 during surgery. The primary parameter was the amount of remifentanil. A total of 52 patients completed the study (24 in the R group, 28 in the C group). The remifentanil dose during surgery was decreased in the R group (29 ± 21 vs. 56 ± 36 ng/kg/min; p = 0.002). Visual analogue scale score and additional administrated analgesics were also low in the R group. As such, AWB can reduce the remifentanil dose while maintaining the same pain level.

Laparoscopic versus open inguinal hernia repair in infants: an initial experience

BACKGROUND

Inguinal hernia repair is a common operation performed in children. In Australia, open repair (OR) continues to be the preferred method of treatment in infants, despite laparoscopic repair (LR) gaining popularity amongst some international centres. Our aim was to analyse initial outcomes with LR at our paediatric centre.

METHODS

We conducted a retrospective review of all patients <1 year of age who received LR or OR between January 2017 and July 2021 at our institution. Data were retrieved from both electronic and scanned medical records. Data were analysed using an unpaired t-test, Mann-Whitney test, Fisher's exact test or simple linear regression. A P-value <0.05 was considered significant.

RESULTS

A total of 376 patients were identified: LR was performed in 73 patients, and OR in 303 patients. Bilateral repair was more common amongst patients receiving LR: 56.2% versus 21.5%, P = 0.0001, treating either a symptomatic hernia or an intra-operative contralateral inguinal defect (70%). All LR patients received general anaesthetic, compared to 82.8% of patients in the OR group, P = 0.0001. There were no recurrences following LR and 3 with OR (P = 1.0). The metachronous contralateral inguinal hernia rate following OR was 10% (21/206). There was no significant difference in other complications, including wound infection, haematoma, testicular atrophy, and hydrocele formation.

CONCLUSION

In our population OR was performed more often than LR. Operative complication rates were equivalent between OR and LR groups. However, infants that underwent OR were significantly more likely to develop a MCIH.

An Evaluation of the Evidence Guiding Adult Midline Ventral Hernia Repair

Purpose:  Several guidelines have been published in recent years to guide the clinician in ventral hernia repair. This review distils this advice, critically assesses their evidence base, and proposes avenues for future study. Methods:  A PUBMED search identified four guidelines addressing midline ventral hernia repair published by major surgical societies between 2016 and 2020. The studies used to inform the advice have been critically appraised, including 20 systematic reviews/meta-analyses, 10 randomized controlled trials, 32 cohort studies, and 14 case series. Results:  Despite a lack of randomized controlled trials, case heterogeneity, and variation in outcome reporting, key themes have emerged. Preoperative computed tomography scan assesses defect size, loss of domain, and the likely need for component separation. Prehabilitation, frailty assessment, and risk stratification are beneficial in complex cases. Minimally invasive component separation techniques, Botox injection, and progressive pneumoperitoneum represent novel techniques to promote closure of large fascial defects. Rives-Stoppa sublay mesh repair has become the "gold" standard for open and minimally invasive repairs. Laparoscopic repair promotes early return to functional status. The enhanced-view totally extraperitoneal approach facilitates laparoscopic sublay mesh placement, avoiding mesh contact with viscera. Robotic techniques continue to evolve, although the evidence at present remains immature. Synthetic mesh is recommended for use in clean and clean-contaminated cases. However, optimism regarding the use of biologic and biosynthetic meshes in the contaminated setting has waned. Conclusions:  Surgical techniques in ventral hernia repair have advanced in recent years. High-quality data has struggled to keep pace; rigorous clinical trials are required to support the surgical innovation.

[Pain and quality of life after laparoscopic transabdominal preperitoneal hernioplasty with different ways of fixing the peritoneum. Results of early completion randomized clinical trial]

OBJECTIVE

To compare and statistically evaluate the severity of pain syndrome and quality of life depending on the method of fixation of the parietal peritoneum during laparoscopic hernia repair (suture fixation or the use of tack fixation).

METHODS

A randomized clinical trial was conducted from May to June 2021 at the Lomonosov Moscow State University Medical Center. It was planned to observe patients for a year. In the first group, the fixation of the parietal peritoneum was performed using suture fixation, in the second group, the peritoneal flap was fixed using a fixation device. In the course of statistical data processing, it was planned to study the dependence of the duration of the operation, the severity of the pain syndrome in the early postoperative period, the frequency of complications, the quality of life of patients in the postoperative period on the chosen method of the fixation of the parietal peritoneum.

RESULTS

At the initial stage of the study, 8 patients with inguinal hernias were selected in the first group during randomization, and 6 patients were selected in the second group. Each patient of the second group in the early postoperative period had a more pronounced local pain, protective muscle tension in the projection of fixation of the parietal peritoneum with tacks, which was accompanied by negative psychoemotional reactions, an increase in the dose of analgesic drugs. Due to the revealed features of the early postoperative period in patients of second group, it was considered unethical and inappropriate to continue the study within the protocol.

CONCLUSION

The results obtained do not allow us to draw statistically supported conclusions. The solution of the problem of the peritoneal flap fixation method is possible in two ways: abandoning stapler fixation in favor of suture or conducting additional clinical studies with an analysis of the impact of the choice of peritoneal fixation technique not only on acute and chronic postoperative pain, but on quality of life in the early and delayed postoperative periods.

Laparoscopic repair of the left paraduodenal hernia: A rare case of an internal hernia

Paraduodenal hernia (PDH) is a rare congenital anomaly, the most common cause of internal hernia. The left-sided PDHs (LPDHs) are more common than the right-sided and are common in male patients at the 4th and 6th years of life. LPDH is been often clinically asymptomatic and often detected by chance in surgical patients. Abdominal computed tomography is the gold standard in diagnosis. PDH can cause ischemia with the high mortality rates due to intestinal obstruction. Therefore, surgical repair should be done as soon as possible after diagnosis. Here, we present a case of LPDH that was laparoscopically diagnosed and repaired early.

Concurrent laparoscopic totally extraperitoneal inguinal hernia repair and transurethral resection of prostate: Breaking with convention - A retrospective study

AIM

This study aimed to evaluate concurrent laparoscopic totally extraperitoneal (TEP) inguinal hernia repair and transurethral resection of the prostate (TURP) with determination of outcomes.

MATERIALS AND METHODS

This retrospective study was conducted at our hospital, from June 2011 to June 2020. Over 9 years, 17 patients with co-existing uncomplicated unilateral or bilateral inguinal hernia (primary/recurrent) and significant benign prostatic hypertrophy were operated in the same sitting. The following outcomes were compared: duration of the surgery, conversion to open hernia surgery, intraoperative and post-operative complications, duration of hospital stay, recurrence, time taken to resume normal activity and cost of the treatment.

RESULTS

This study included 17 patients with a mean age of 65 years (range of 50-87 years). The average time taken for the surgery was 115 min with no conversion to open hernia repair. The mean post-operative stay was 3.7 days. There were four patients (23.5%) with seromas identified at day 10, only two remained at 6 weeks and none at 12 weeks. None had significant bleeding intraoperatively or postoperatively. There was no superficial or deep wound infection (including mesh infection). There was no recurrence of inguinal hernia. Two patients (11.7%) developed post-TURP urethral stricture and underwent cystoscopic stricturoplasty, 3 and 2.5 months after the initial procedure. The time taken to resume normal activity was 7 (±1) days. The hospital cost is reduced by 25% as compared to the sum of costs when both the operations are done separately.

CONCLUSION

Concurrent TEP inguinal hernia repair and TURP is a practical, safe and cost-effective procedure.

Non-closure of the Free Peritoneal Flap During Laparoscopic Hernia Repair of Lower Abdominal Marginal Hernia: A Retrospective Analysis

Background: During lower abdominal marginal hernia repair, the peritoneal flap is routinely freed to facilitate mesh placement and closed to conclude the procedure. This procedure is generally called trans-abdominal partial extra-peritoneal (TAPE). However, the necessity of closing the free peritoneal flap is still controversial. This study aimed to investigate the safety and feasibility of leaving the free peritoneal flap in-situ. Methods: A retrospective review was conducted on 68 patients (16 male, 52 female) who underwent laparoscopic hernia repair between June 2014 and March 2021. Patients were diagnosed as the lower abdominal hernia and all required freeing the peritoneal flap during the operation. Patients were divided into 2 groups: one group was TAPE group with the closed free peritoneal flap, another group left the free peritoneal flap unclosed. Analyses were performed to compare both intraoperative parameters and postoperative complications. Results: There were no significant differences in demographic, comorbidity, hernia characteristics and ASA classification. The intra-operative bleeding volume, visceral injury, hospital stay, urinary retention, visual analog scale (VAS) score, dysuria, intestinal obstruction, surgical site infection, mesh infection, recurrence rate and hospital stay were similar among the two groups. Mean operative time of the flap closing procedure was higher than for patients with the free peritoneal flap left in-situ (p = 0.002). Comparisons of postoperative complications showed flap closure resulted in a higher incidence of seroma formation (p = 0.005). Conclusion: Providing a barrier-coated mesh is used during laparoscopic lower abdominal marginal hernia repair, it is safe to leave the free peritoneal flap in-situ and this approach may prevent the occurrence of seromas.

Safety and Feasibility of Laparoscopic Transabdominal Preperitoneal Hernia Repair for Octo- and Nonagenarians

Background: The feasibility of laparoscopic hernia repair in octo- and nonagenarians has not been investigated in detail. The aim of this retrospective study was to evaluate the safety and feasibility of laparoscopic hernia repair in octo- and nonagenarians. Methods: This study included 607 patients who underwent transabdominal preperitoneal laparoscopic hernia repair at our hospital between April 2014 and October 2020. Patients were divided into an over 80 group (112 patients aged 80 years and older) and a control group (495 patients younger than 80 years). The clinical outcomes were compared between the groups. In addition, among patients aged 80 years and older, those who underwent elective laparoscopic hernia repair (laparoscopic group: 111 patients) were compared with patients who underwent elective open hernia repair during the same study period (open group: 79 patients). Results: The number of patients who underwent bilateral hernia repair was significantly larger in the over 80 group (26.7% versus 11.7%, P < .001). The incidence of postoperative complications was not significantly different between the over 80 group and the control group. Compared with open group, the number of patients who underwent bilateral hernia repair was significantly larger in the laparoscopic group (27.0% versus 2.5%, P < .001). The incidence of postoperative complications (2.7% versus 10.1%) and the incidence of readmission (0.9% versus 6.3%) were significantly greater in the open group. Conclusions: Laparoscopic hernia repair in octo- and nonagenarian patients yields safe and noninferior outcomes. Laparoscopic hernia repair in octo- and nonagenarian patients is considered more suitable for detecting and repairing contralateral hernias simultaneously.

Comparison of Recurrence and Complication Rates Following Laparoscopic Inguinal Hernia Repair among Preterm versus Full-Term Newborns: A Systematic Review and Meta-Analysis

Background: Laparoscopic inguinal hernia repair (LHR) in children has been widely performed in the last decades, although it is still not sufficiently researched in preterm infants. This systematic review and meta-analysis compared the recurrence and complication rates following laparoscopic hernia repair among preterm (PT) versus full-term (FT) newborns. Methods: Scientific databases (PubMed, EMBASE, Scopus, and Web of Science databases) were systematically searched for relevant articles. The following terms were used: (laparoscopic hernia repair) AND (preterm). The inclusion criteria were all preterm newborns with a unilateral or bilateral inguinal hernia who underwent LHR. The main outcomes were the incidence of recurrence of hernia and the proportion of children developing postoperative complications in comparison with FT newborns following LHR. Results: The present meta-analysis included four comparative studies. Three studies had a retrospective study design while one was a prospective study. A total of 1702 children were included (PT n = 523, FT n = 1179). The incidence of hernia recurrence showed no significant difference between the PT versus FT groups (RR = 2.58, 95% CI 0.89–7.47, p = 0.08). A significantly higher incidence of complications was observed in the PT group compared to the FT group (RR = 4.05, 95% CI 2.11–7.77, p < 0.0001). The PT group of newborns accounted for 81% and 72% of the major and minor complications. The major complications were either non-surgical (i.e., severe respiratory distress requiring reintubation with prolonged ventilation (or high-frequency ventilation), seizures, bradycardia), or surgical (i.e., hydroceles requiring operative intervention and umbilical port-site hernia). Conclusions: LHR in PT infants is associated with similar recurrence rates as in FT infants. However, the incidence of complications is significantly higher in PT versus FT infants.

Mesh fixation with fibrin glue versus tacker in laparoscopic totally extraperitoneal inguinal hernia repair

BACKGROUND

The advent of mesh was a breakthrough in the field of hernia surgery. Mechanical methods of mesh fixation are hypothesized to cause more tissue trauma than nonmechanical methods. The present study was conducted to study the outcomes of mesh fixation using fibrin glue, a nonmechanical method versus tackers in totally extraperitoneal repair (TEP) of unilateral inguinal hernia.

METHODS

A randomized controlled single blinded study was conducted in India from June 2017 to March 2019. Patients diagnosed with unilateral uncomplicated inguinal hernia with a hernial sac of size not more than 5 cm were invited to participate in the study. Sample size was 60 patients randomized into groups just before mesh fixation. In group A mesh was fixed using tackers while in group B mesh was fixed using fibrin glue. Patients were followed-up prospectively for 3 months.

RESULTS

There was no statistical difference between the two groups with respect to operating time. Average hospital stay and pain scores at all follow-ups were better for fibrin glue group. There was no difference in the incidence of postoperative urinary retention, seroma formation and hematoma formation between the two groups. Patients of fibrin glue group had early restart of daily activities at 15 days follow-up when compared to tacker group.

CONCLUSION

Fibrin glue fixation technique should be advocated over tackers for mesh fixation in TEP considering the better outcomes and cost-effectiveness of the technique.

Technique and Outcomes in Laparoscopic Repair of Morgagni Hernia in Adults

Background: Morgagni hernias (MHs) are rare anteromedial congenital diaphragmatic hernias. This study describes the effectiveness of a laparoscopic approach for these defects. Methods: A prospectively collected institutional database at a tertiary referral center was queried for patients (≥18 years) with MHs. Results: Fifteen adults underwent laparoscopic MH repair. Abdominal pain was the most common presentation (71.5%), and 2 patients (13.3%) presented with acute obstruction. Laparoscopic bridged mesh repair was the most common approach (66.7%) and was achieved by suturing a bridged synthetic mesh to the diaphragmatic portion of the defect and fixing it with transfascial sutures and/or tacks to the anterior abdominal wall. Primary suture repair was utilized for smaller defects. No mortalities or recurrences occurred after 20.2 months median follow-up. Conclusions: Laparoscopic synthetic mesh repair of adult MHs offers an effective hernia repair with minimal complications and no detected recurrences in long-term follow-up of this patient sample.

The Operative Time for Unilateral Inguinal Hernia Repair in Children Performed with Percutaneous Internal Ring Suturing (PIRS) or Open Approach Method

In this study, we compared the operative time for unilateral inguinal hernia repair in children performed with either an open approach (OA) or the Percutaneous Internal Ring Suturing (PIRS) method. It was a retrospective chart review of all patients ages 0 to 18 who underwent unilateral inguinal hernia repair in the Department of Pediatric Surgery, Urology and Traumatology of the Regional Hospital in Kielce between January 2011 and December 2018. Patients with bilateral hernias or additional problems were excluded. Of 878 patients qualified for the study, 701 were in the OA group and 177 in the PIRS group. Overall, the time needed to complete the procedure was significantly longer for the OA method. The operative time was longer if the hernia was left-sided (p = 0.024). Analysis by gender showed that operative time was generally longer in males. For both genders, surgery was shorter if the PIRS method was used. For males in the PIRS group the operative time was affected by the location of the hernia, and it was longer for a left-sided hernia. The take-home message is that the PIRS procedure is faster than the OA for inguinal hernia repair in children and it might be considered as a preferred method, especially in females.

The Comparison of Balloon and Camera Dissection of the Preperitoneal Space in Totally Extraperitoneal Repair Hernia Repair. Our Initial Experience!

Purpose. To perform totally extraperitoneal repair of a hernia, it is essential to create a working space for the placement of instruments. In this study, we aimed to compare balloon dissection (BD) and camera or telescopic dissection (CD) with respect to the surgical outcomes, without considering the cost-effectiveness. Methods. Forty consecutive, healthy, unilateral inguinal hernia patients who underwent Totally Extraperitoneal Repair hernia repair were randomized into 2 groups according to whether they received BD or CD. The perioperative demographic characteristics were recorded. All the operations were video recorded from the beginning to the end of each procedure. The virtually constructed periods of the procedures were evaluated by another surgeon who watched each video. The time spent for each period, the severity score assigned by the surgeon, the total operation time, the peritoneal laceration rate, the presence of early and late postoperative pain, the number of postoperative visits, the total analgesic requirements, and the complications were recorded. Results. The demographic properties of the patients, the perioperative and postoperative complications, and the severity scores in the BD and CD groups were statistically similar. The total operating time and the time from the dissection of the peritoneum to the reduction of the hernia sac were significantly longer in the CD group. Post-discharge analgesic consumption, Visual Analog Scale scores, and the number of visits were similar between the groups. Conclusions. The dissection of the working space in the preperitoneal area can be achieved using camera dissection without the risk of common complications associated with balloon dissection, particularly balloon rupture.

Comparison of efficacy and safety of the enhanced-view totally extraperitoneal (eTEP) and transabdominal (TARM) minimal access techniques for retromuscular placement of prosthesis in the treatment of irreducible midline ventral hernia

Background:

Retromuscular plane for mesh placement is preferred for ventral hernia repair. With the evolution of minimal access surgeries, newer techniques to deploy a mesh in the sublay plane have evolved. We compared two such minimally invasive approaches for repair of irreducible ventral midline hernia with respect to the efficacy and safety of the procedures.

Patients and Methods:

This is a retrospective study of a prospectively maintained database of 73 patients operated with retromuscular placement of mesh for irreducible ventral midline hernia by enhanced-view totally extraperitoneal (eTEP) or transabdominal retromuscular (TARM) repair. We recorded and compared the intraoperative and post-operative complications, post-operative pain score, recovery, recurrence, subjective technical ease of procedure and patient satisfaction after 3 months and 12 months of the surgery.

Results and Conclusion:

Thirty-eight patients were operated by eTEP technique and the subsequent 35 were operated by TARM repair. There was no significant difference in the outcome of surgery and complications by the two techniques. However, there was a significant subjective technical ease in the TARM group due to ergonomic triangulated port placement and adhesiolysis and reduction of hernia contents under vision. The number of ports used and post-operative pain were, however, higher in the TARM group as compared to that of the eTEP group. Nearly 96% of the patients belonging to both groups were satisfied with their surgery after a year on telephonic follow-up. However, further studies and follow-up of patients would be required to establish the advantage of one technique over the other.

[Outcomes of various techniques of mesh prosthesis fixation in laparoscopic hernia repair]

OBJECTIVE

To compare early and long-term results of various mesh prosthesis fixation methods in laparoscopic inguinal hernia repair.

MATERIAL AND METHODS

It is a prospective clinical non-randomized trial. The study included 212 patients. Conventional stapler fixation (112 patients), self-gripping mesh implants (48 patients) and n-butyl cyanoacrylate adhesive fixation (52 patients) were compared. We estimated surgery time, pain syndrome severity in early and long-term postoperative period, postoperative morbidity and recurrence rate were evaluated.

RESULTS

Early postoperative morbidity, activation of patients and hospital-stay were similar in all groups. Pain syndrome within 6 postoperative hours in the first group exceeded the same parameter in the second group by 1.23 times (95% CI 1.15-1.31, p<0.05) and by 1.19 times in the third group (95% CI 1.12-1.26, p<0.05). Within 12 hours, pain syndrome in the first group was 1.27 times more severe compared to the third group (95% CI 1.20-1.34, p<0.05). Pain syndrome in long-term period was similar in all groups. In the first group, one recurrence was detected (0.9%).

CONCLUSION

There were no significant between-group differences. However, we found the correlation of postoperative pain syndrome with mesh implant fixation technique.

[Minimally invasive correction of anatomical features of anterior abdominal wall and ventral hernias]

Conventional «open» procedures for ventral hernias and diastasis recti are widely known, used everywhere and have a great number of author's improvements related to surgeon's experience, availability of modern information, equipment and materials. K. LeBlanc and W. Booth (1993) reported IPOM-method with non-adhesive coating that is considered a milestone in surgery of anterior abdominal wall and ventral hernia. This technique has gained recognition among surgeons around the world due to its technical simplicity, minimal invasiveness and high reproducibility. However, certain disadvantages of this technique have been shown over the past time that justified advisability of searching for another methods of anterior abdominal wall reinforcement. Thus, E-Milos, LIRA, TESAR, eTEP, REPA, TARM, TARUP techniques are currently available. This review is devoted to technical features of these techniques, their potential advantages and disadvantages.

Laparoscopic Repair of Extraperitoneal Ureteral Inguinal Hernia With Mesh Placement

Ureteral inguinal hernias are a well-described entity, within the spectrum of sliding hernias, with over 140 cases described since 1880. Though herniation of the ureter is relatively rare and complete ureteric obstruction is infrequent, a massive herniation may cause complete obstruction, leading to hydronephrosis. Management of these hernias is challenging and poses a significant danger of inadvertent injury and entrapment of a tortuous ureter. When faced with this type of hernia, extreme care should be taken to perform the appropriate preoperative workup and thoroughly plan the surgical approach. The present case describes a patient with a known ureteral inguinal hernia, who underwent a laparoscopic repair of the hernia with mesh placement.

Ovarian Incarceration and Torsion in Single-Ovary Versus Multiple-Reproductive Organ Prolapse in Female Inguinal Hernia: A Retrospective Study of 510 Infants Who Underwent Laparoscopic Hernia Repair

Purpose: Although inguinal hernia repair is common in infants, few studies have focused on the condition in female infants. In female infantile inguinal hernia, there is a risk of oophorectomy when torsion and strangulation occur due to ovarian prolapse. We aimed to evaluate the risks of ovarian incarceration and torsion in single-ovary versus multiple-reproductive organ prolapse in female infantile inguinal hernia. Methods: Females ≤12 months old who underwent laparoscopic transabdominal inguinal hernia repair from September 2012 to December 2019 were retrospectively analyzed. If manual reduction failed at initial diagnosis, surgery was performed within 24 hours in all incarceration cases. The clinical characteristics and surgical outcomes were compared between those with single-organ versus multiple-organ prolapse. Results: Of 510 patients, 465 (91.2%) had single-organ prolapse, most commonly a single ovary (381/465), followed by intestine (84/465). Forty-five patients (8.8%) had multiple-organ prolapse, most commonly a single ovary plus intestine (27/45), followed by both ovaries plus the uterus (10/45). The manually irreducible incarceration rate was higher in patients with multiple-organ prolapse (57.8%) than single-organ prolapse (23.4%; P < .000). In patients with ovarian incarceration, the ovarian torsion rate was higher in the single-ovary group (38/109, 34.9%) than the multiple-organ group (1/26, 3.8%; P < .000). There was no significant difference between the two groups in recurrence or oophorectomy rate. Conclusion: Most female infantile inguinal hernias involve ovarian prolapse. There is a high risk of incarceration in multiple-organ prolapse and a high risk of ovarian torsion in single-ovary prolapse.

Laparoscopic Total Extraperitoneal Groin Hernia Repair in Females: Comparison of Outcomes Between Preservation or Division of the Uterine Round Ligament

Background: Laparoscopic repair has been recommended as the method-of-choice of groin hernia repair among women. Whether the round ligament of uterus should be divided to facilitate mesh placement remains controversial. This study aims to review the outcomes of laparoscopic total extraperitoneal (TEP) groin hernia repair in women and to evaluate the impact of division of round ligament. Methods: Consecutive female patients with inguinal or femoral hernias who underwent elective laparoscopic TEP repair at a single institution from 2006 to 2017 were included for retrospective analysis. Primary outcomes were postoperative pain, genital prolapse, and recurrence. Outcomes of patients who had the round ligament divided were further compared with those with round ligament preserved and multivariable adjusted analysis was performed. Results: Sixty-eight patients with a total of 77 TEP repairs were included in the 12-year study period. The mean age was 45 ± 16 years old. Incidental femoral hernia was identified in 4 patients (5.9%). There was 1 (1.3%) recurrence upon mean follow-up of 42.9 ± 37.3 months. The round ligament was divided in 67.5% of patients, and upon multivariable adjusted analysis, there were no statistically significant differences in outcomes in terms of chronic pain (odds ratio [OR] = 2.210, P = .357), paresthesia (OR = 0.241, P = .149), and genital prolapse (OR = 0.327, P = .415) when compared with patients with preserved round ligament. Conclusion: Laparoscopic groin hernia repair in women is associated with low recurrence. Division of round ligament intraoperatively facilitates mesh placement and has minimal impact on clinical outcomes.

Combination of Polypropylene Mesh and in Situ Injectable Mussel-Inspired Hydrogel in Laparoscopic Hernia Repair for Preventing Post-Surgical Adhesions in the Piglet Model

Polypropylene (PP) mesh has been used successfully for a long time in clinical practice as an impressive prosthesis for ventral hernia repair. To utilize a physical barrier for separating mesh from viscera is a general approach for preventing adhesions in clinical practice. However, a serious abdominal adhesion between the mesh and viscera can possibly occur post-hernia, especially with the small intestine; this can lead to a series of complications, such as chronic pain, intestinal obstruction, and fistula. Thus, determining how to prevent abdominal adhesions between the mesh and viscera is still an urgent clinical problem. In this study, a dopamine-functionalized polysaccharide derivative (oxidized-carboxymethylcellulose-g-dopamine, OCMC-DA) was synthesized; this was blended with carboxymethylchitosan (CMCS) to form a hydrogel (OCMC-DA/CMCS) in situ at the appropriate time. The physical and chemical properties of the hydrogel were characterized successfully, and its excellent biocompatibility was presented by the in vitro cell test. The combination of this hydrogel and PP mesh was used in laparoscopic surgery for repairing the abdominal wall defect, where the hydrogel could become fixed in situ on the PP mesh to form an anti-adhesion gel-mesh. The results showed that the gel-mesh could prevent abdominal adhesions effectively in the piglet model. Moreover, the histology and immunohistochemical staining proved that the gel-mesh could effectively alleviate the inflammation reaction and deposition of collagen around the mesh, and it did not disturb the integration between mesh and abdominal wall. Thus, the gel-mesh has superior tissue compatibility.

Retromuscular Mesh Repair Using Extended Totally Extraperitoneal Repair Minimal Access: Early Outcomes of an Evolving Technique-A Single Institution Experience

Background: Enhanced-view extended totally extraperitoneal repair (eTEP) technique for laparoscopic retromuscular ventral hernia (VHR) repair is a novel application recently described by some authors. We present our early single institution experience on this technique. Methods: Retrospective review of the eTEP technique for laparoscopic retromuscular VHR repair cases at our institution from October 2018 to June 2019 with 1 month follow-up was evaluated. Data analyses include patients characteristics, operative details, and complications. Results: A total of 18 patients were treated with eTEP. One patient was reoperated using the same procedure and hospital stay was 6 days. The same patient who had undergone transversus abdominis release developed a seroma that could be observed 20 days after surgery. Conclusion: Our short-term experience with eTEP access suggests feasibility of this approach in accordance with results from other authors. We do not think the technique is challenging, but it is necessary for it to be performed by surgeons with skills in laparoscopic abdominal wall reconstruction.

A minimally invasive treatment of an asymptomatic case of mesh erosion into the caecum after total extraperitoneal inguinal hernia repair

BACKGROUND

Mesh migration and erosion into adjacent viscera is a rare complication after laparoscopic inguinal hernia repair. We present a minimally invasive treatment of an asymptomatic case of mesh erosion into the caecum after total extraperitoneal inguinal hernia repair, including an overview of the relevant recent literature.

METHODS

A male patient underwent a laparoscopic inguinal hernia repair at the age of 42. Two years after this procedure, a screening colonoscopy revealed erosion of the mesh into the caecum. A laparoscopy was performed with partial resection of the mesh and minimal resection of the involved colon. Results of a systematic review of English PubMed articles on mesh migration and erosion after inguinal hernia repair is presented.

RESULTS

We report a first-time minimally invasive treatment of mesh erosion into the colon. A laparoscopic approach is feasible and provides an excellent exposure. Partial removal of the mesh is suggested in uncomplicated cases to avoid complications associated with complete mesh removal.

Modified Implantation of Self-Adhesive Mesh in Laparoscopic Total Extraperitoneal Inguinal Hernia Repair

Introduction: The self-adhesive mesh has become increasingly popular since its launch and has been proven to be reliable in laparoscopic hernia reparation. However, self-adhesive mesh may encounter unexpected adhesions during operation because one side of the mesh was covered with microgrips. Objective: Performing a modified technique of self-adhesive mesh implantation to avoid unexpected adhesions to the mesh itself and to the surrounding tissues in the operation space. Methods: We carried out a modified self-adhesive mesh implantation during May 2017 and March 2018. The modification was using a plastic membrane to cover the microgrips side of the mesh, and then rolling up the mesh to a cigarette shape. The mesh was inserted into the groin through a 10 mm trocar, and it was opened up with the membrane being removed meanwhile. Results: A total of 21 cases of laparoscopic total extraperitoneal inguinal hernia repair were successfully performed. The mesh could be conveniently put on the right place with no unexpected adhesions and the operation time was greatly shortened by using this modified technique. Conclusion: Putting a plastic membrane on the microgrips side of the self-adhesive mesh could avoid the mesh adhering itself when rolling up and could be easy to spread up the mesh in the operative field without unexpected adhesions, which simplified the surgical process and shortened the surgical duration.

Primary lumbar hernia: A rare case report and a review of the literature

Primary lumbar hernia is a rarely encountered hernia. Surgical correction is the standard treatment for lumbar hernia, and either an open or laparoscopic procedure can be performed with equivalent success. However, open repairs are most commonly performed. Here, we present a case of a primary lumbar hernia that was successfully treated laparoscopically and discuss surgical modalities of treatment reported in the literature. There are two laparoscopic approaches: transabdominal and extraperitoneal. The main advantage of the laparoscopic approach is that it helps the surgeon to precisely locate and evaluate the characteristics of the defect. It also has a lower morbidity rate, shorter length of hospital stay, less postoperative pain, and an earlier return to daily routine activities than the open approach. In the present study, a patient with a superior lumbar hernia was treated laparoscopically by the transabdominal approach. Laparoscopic repair in such cases is feasible and achieves a good result when done by an experienced laparoscopic hernia surgeon.

Dexmedetomidine Effect on Emergence Agitation and Delirium in Children Undergoing Laparoscopic Hernia Repair: a Preliminary Study

Objective To evaluate the safety and efficacy of dexmedetomidine (Dex) to prevent emergence agitation (EA) and delirium (ED) in children undergoing laparoscopic hernia repair under general anesthesia. Methods 100 children (1-5 years, 10-25 kg) were randomized into four groups: controls (saline) and intravenous Dex at 0.25, 0.5, and 1.0 µg/kg (D1, D2, D3, respectively). Dex/saline infusion was started following anesthesia. EA and ED were evaluated on a 5-point scale. Results For the C, D1, D2, and D3 groups, respectively, EA frequencies were 45.8%, 30.4%, 12%, 4%; ED frequencies 29.1%, 13%, 4%, 4%; CHIPPS scores 8, 6, 3, 3; sevoflurane doses from 13.2 ± 3.4 (controls) to 9.4 ± 3.5 ml (D3). Intervals until mask removal/spontaneous eye opening were significantly longer for D2 and D3 than controls. PACU stay was longer for D3. Conclusions There was significantly less postoperative EA and pain, with less sevoflurane required, using Dex.

Are routine ultrasound examinations helpful in the detection of bleeding complications following laparoscopic inguinal hernia repair?

PURPOSE

Intraabdominal bleeding is a dreaded complication after laparoscopic transabdominal preperitoneal inguinal hernia repairs. Routine postoperative sonographic (US) examination and hemoglobin measurement have been suggested to identify bleeding after surgery. We retrospectively assessed the value of these tests.

METHODS

A total of 995 consecutive patients admitted for laparoscopic inguinal hernia repair to a single teaching hospital were analyzed. US examinations were performed postoperatively on the operative day to identify intraabdominal bleeding. In addition, hemoglobin measurements were obtained on the first postoperative day.

RESULTS

Postoperative US examinations were performed on 971 patients (97.6%). Of these, 945 were examined within 24 hours of surgery. Reoperation was necessary in 1.1% (11/995) of the patients because of a persistent seroma in five cases, intraabdominal or inguinal bleeding or hematomas in five cases, and a trocar hernia in one case. In none of the 11 patients requiring reoperation did US examination or hemoglobin measurement indicate acute bleeding or hematoma.

CONCLUSIONS

Routine postoperative US examination and hemoglobin measurement within the first 24 hours of surgery are not suitable for identifying patients with intraabdominal bleeding who require a reoperation. Instead, US examination and hemoglobin measurement should be part of the patient workup when there is a clinical suspicion of a postoperative complication. © 2016 Wiley Periodicals, Inc.

Randomised controlled trial of n-butyl cyanoacrylate glue fixation versus suture fixation of mesh in laparoscopic totally extraperitoneal hernia repair

BACKGROUND:

We present a randomised control trial to compare suture fixation of the mesh with non-mechanical fixation using n-butyl cyanoacrylate (NBCA) glue for laparoscopic totally extraperitoneal (TEP) hernioplasty.

PATIENTS AND METHODS:

After a standard dissection for laparoscopic TEP hernioplasty, the mesh was fixed using sutures or NBCA glue to the Cooper's ligament as per the randomised allocation. The primary endpoints were recurrence at 24 months and chronic groin pain. The secondary endpoints were pain scores, analgesic requirement in the post-operative period and duration of surgery.

RESULTS:

Group A consisting of suture fixation had 127 patients which included a total of 173 hernias while Group B consisting of NBCA had 124 patients including a total of 171 hernias. The patients’ age, sex distribution, body mass indices and co-morbidities were comparable in both groups. No patient suffered any major intra-operative or post-operative complication or mortality. There were no conversions to open surgery in either of the groups. The operating time was similar in both the groups though there was a tendency toward a shorter surgery time in Group B. There was lesser consumption of analgesics in the immediate post-operative period in Group B but this did not reach statistical significance. Using visual analogue scale to measure pain, there was no difference in pain at 48 h; however, Group B patients complained of significantly less pain on day 7 as compared to Group A. Almost 98% of Group A patients and 99.2% of Group B patients completed 24 months of follow-up. There were no recurrences in either groups or was there any significant difference in chronic groin pain, in fact, none of the Group B patients complained of chronic groin pain.

CONCLUSION:

Using NBCA glue to fix the mesh in laparoscopic TEP hernia repair is effective and associated with less pain on day 7 as compared to suture fixation of the mesh.

Innovation in Laparoscopic Inguinal Hernia Reparation - Initial Experiences with the Parietex Progrip Laparoscopic(™) - Mesh

Introduction

The Laparoscopic TAPP (transabdominal pre-peritoneal inguinal hernia repair) – technique is becoming more widely and frequently used due to higher patient satisfaction and lower rates of both relapse and complications.

Materials and methods

The role of the fixation of the mesh is especially important in regard to the endoscopic technique. The fixation of mesh through penetrating techniques using staples, clips, or screws is associated with a significantly increased risk of developing a chronic post-herniotomy inguinal pain syndrome (CPIP). In order to answer the question “fixation or no fixation of the mesh,” the use of self-adhesive mesh is an optimal compromise.

Conclusion

With the authors own operative technique consisting also of a standard pre- and post-operative management, the self-adhesive mesh was proven to be extremely reliable. As no specific materials to fix the mesh were needed, the method was fast, simple, and economical. We could also reduce the incidences of chronic inguinal pain in our patient population by using the self-adhesive mesh, without the risk of an increased recurrence rate in the observation period.

Laparoscopic Hernia Repair With 3-Millimeter Instruments: A Point of Technique and Illustrative Case Video

The repair of inguinal hernia has been a controversial issue in surgical practice since its conception. The article demonstrates that use of 3 mm instruments can be incorporated in Laparoscopic hernia repair. The second aim of this article is that use of TAP block (Transverse abdominal plane block) without curare is efficient, safe and reproducible.

Laparoscopic repair of incisional and ventral hernias with the new type of meshes: randomized control trial

Introduction

Laparoscopic incisional and ventral hernia repair (LIVHR) was first reported by Le Blanc and Booth in 1993. Many studies are available in the literature that have shown that laparoscopic repair of incisional and ventral hernia is preferred over open repair because of lower recurrence rates (less than 10%), less wound morbidity, less pain, and early return to work.

Aim

To identify the long-term outcomes between the different types of meshes and two techniques of mesh fixation, i.e., tacks (method Double crown) and transfascial polypropylene sutures.

Material and methods

A total of 92 patients underwent LIVHR at our department between January 2009 and August 2012. The hernias were umbilical in 26 patients, paraumbilical in 15 patients and incisional in 51 patients. All patients admitted for LIVHR were randomized to either group I (tacker fixation of ePTFE meshes) or group II (suture fixation of meshes with nitinol frame) using computer-generated random numbers with block randomization and sealed envelopes for concealed allocation.

Results

The mean mesh fixation time was significantly higher in the tacker fixation group (117 ±15 min vs. 72 ±6 min, p < 0.01). There were no conversions in either group. The median postoperative hospital stay was 3.5 ±1.5 days. All patients were followed up at 1, 3, 6, 12 and every 6 months thereafter postoperatively. There were 5 recurrences in the study population. In group I there were 4 patients with recurrence, and only 1 patient in the group with meshes with a nitinol frame.

Conclusions

Meshes of the new generation with a nitinol framework can significantly improve laparoscopic ventral hernia repair. The fixation of these meshes is very simple using 3–4 transfascial sutures. The absence of shrinkage of these meshes makes the probability of recurrence minimal. Absence of tackers allows postoperative pain to be minimized. We consider that these new meshes can significantly improve laparoscopic ventral hernia repair.

Laparoscopic inguinal hernia repair in children using the percutaneous internal ring suturing technique - own experience

INTRODUCTION

Percutaneous internal ring suturing (PIRS) is a method of laparoscopic herniorrhaphy, i.e. percutaneous closure of the internal inguinal ring under the control of a telescope placed in the umbilicus.

AIM

To evaluate the usefulness of the PIRS technique.

MATERIAL AND METHODS

Fifty-five children (39 girls and 16 boys) underwent surgery using this method in our institution between 2008 and 2010.

RESULTS

In 10 cases the presence of an open inguinal canal on the opposite side was also noted during surgery, and umbilical hernia was recognized in 2 patients. In 5 cases it was necessary to convert to the open surgery because of the inability to continue the laparoscopic procedure. In 1 case, male pseudohermaphroditism was diagnosed during surgery. Recurrent inguinal hernia required a conventional method of surgery in 1 child. Other children did not exhibit the characteristics of hernia recurrence. The inguinal canals were followed up with postoperative ultrasound examination in 29 children. In 23 children, the ultrasound examination showed no dilatation of the inguinal canal. In the other 6 children dilatation of the inguinal canal or the presence of fluid within the inguinal canal was observed during ultrasound. In 6 children symptoms such as swelling and soreness around the inguinal canal developed within 3 to 6 months after surgery.

CONCLUSIONS

Inguinal hernia surgery using the PIRS procedure is an alternative, effective, minimally invasive method of surgery. Visualization of the peritoneal cavity allows for detection of other abnormalities, as well as for performing other procedures during the same session (such as closing the contralateral inguinal canal or umbilical hernia surgery).

Infected inguinal hernia mesh presenting as pseudotumor of the bladder

Pseudotumors are uncommon benign tumors considered as a reactive inflammatory lesion. We report a case of a 53-year-old male with a history of right laparoscopic hernia repair and now referred for suspected urachal cyst. Imaging investigations revealed an abdominal mass arising from the wall of the urinary bladder. During dissection, we found a tumor arising from the urinary bladder infiltrating the posterior wall of rectus muscles and further dissection revealed presence of the previously placed inguinal mesh. Postoperative histopathological examination revealed inflammatory pseudotumor. With only one comparable case described, an infected mesh presenting as pseudotumor of the bladder is extremely rare.

Minimally invasive spigelian hernia repair

INTRODUCTION

Spigelian hernia is an uncommon ventral hernia characterized by a defect in the linea semilunaris. Repair of spigelian hernia has traditionally been accomplished via an open transverse incision and primary repair. The purpose of this article is to present 2 case reports of incarcerated spigelian hernia that were successfully repaired laparoscopically using Gortex mesh and to present a review of the literature regarding laparoscopic repair of spigelian hernias.

METHODS

Retrospective chart review and Medline literature search.

RESULTS

Two patients underwent laparoscopic mesh repair of incarcerated spigelian hernias. Both were started on a regular diet on postoperative day 1 and discharged on postoperative days 2 and 3. One patient developed a seroma that resolved without intervention. There was complete resolution of preoperative symptoms at the 12-month follow-up.

CONCLUSION

Minimally invasive repair of spigelian hernias is an alternative to the traditional open surgical technique. Further studies are needed to directly compare the open and the laparoscopic repair.

Total extraperitoneal preperitoneal laparoscopic hernia repair using spinal anesthesia

BACKGROUND

Laparoscopic herniorrhaphy is a well-debated approach to inguinal hernia repair. Multiple technical and outcome variables have been compared with those of traditional open inguinal hernia repairs. One of these variables is the choice of anesthesia. To date, no reports describe the use of spinal anesthesia for laparoscopic hernia repairs. We present herein a review of our experience with spinal anesthesia for the total extraperitoneal preperitoneal laparoscopic hernia repair (TEP).

METHODS

We prospectively reviewed 30 patients undergoing TEP while under spinal anesthesia. Methods of anesthesia, surgical procedure, operative and anesthesia delivery times, as well as outcomes were reviewed. Patients were followed up over a 2-year period. Short- and long-term results of the surgical procedure and anesthesia delivered were noted.

RESULTS

All patients underwent successful laparoscopic hernia repair while under spinal anesthesia without conversion to general anesthesia. Forty-four hernias were repaired in 30 patients. Short- and long-term follow-up (2 years) revealed no significant untoward affects from the spinal anesthesia in this series of patients. Aside from inguinodynia in 3 patients in the short-term, no other short-term or long-term untoward sequelae occurred.

CONCLUSIONS

Spinal anesthesia is a feasible, and in our experience, the preferable method of anesthesia for total extraperitoneal laparoscopic hernia repair.

Diagnosis and laparoscopic repair of type I obturator hernia in women with chronic neuralgic pain

BACKGROUND

We performed a pilot study review of 7 female patients suffering with obturator neuralgia produced by a type I obturator hernia. Diagnosis and laparoscopic treatment of this rare hernia are presented.

METHODS

Patients with chronic pelvic pain and signs of obturator neuralgia were identified retrospectively by chart review. These patients had been referred to our chronic pelvic pain clinic. Outcomes of their surgery from February through November 2001 were analyzed. Median length of follow-up was 11 months (range, 6 to 16). A new technique using Cooper's ligament and arcus tendineus fasciae pelvis was used for the tension-free mesh hernia repair.

RESULTS

In this pilot study, 6 of 7 patients (86%) received greater than 50% relief of their chronic pelvic pain, which leads to the conclusion that we have at least 95% confidence that the pain reduction achieved is greater that 50%. Due to the small sample size, no statistically meaningful conclusions could be reached. All of the patients have reported some pain relief and increased function since surgery.

CONCLUSION

Symptomatic type I obturator hernias may be more common than previously thought. Patients with obturator neuralgia, persisting longer than 6 months despite conservative therapy, may respond to laparoscopic reduction of the pilot fat tag and mesh overlay of the obturator canal.

Laparoscopic herniorrhaphy with porcine small intestinal submucosa: a preliminary study

INTRODUCTION

Using mesh or a synthetic prosthesis during the laparoscopic repair of inguinal hernias has been demonstrated to be safe and effective. A new material, porcine small intestinal submucosa (SIS mesh), has been successfully used in canine and rodent animal models with excellent results. This mesh is degradable and resorbable with a marked decrease in the possibility of becoming infected. However, the amount of fibroblast ingrowth is equal to that with polypropylene mesh.

METHODS

A comparison was made between this new SIS mesh to repair 15 inguinal hernias in 12 patients and polypropylene mesh used in 12 similar patients. A preperitoneal approach with balloon dissection was used in all patients.

RESULTS

Demographics were similar in both groups. The results were excellent and compared equally. Complications (seroma, discomfort) were minimal in both groups and were similar.

CONCLUSIONS

Porcine small intestinal submucosa, SIS mesh, can be used for laparoscopic repair of inguinal hernias. Long-term follow-up will be necessary to confirm these preliminary results.

The role of laparoscopy in the management of groin hernia

INTRODUCTION

The advantage of using minimally invasive techniques over open techniques in the repair of groin hernias is still debated. Despite its more widespread use, an apparent dichotomy exists. While some surgeons continue to believe that no advantage is gained using the laparoscopic technique, others argue laparoscopic hernia repair (LHR) offers a quicker recovery with the use of a tension-free repair.

METHODS

A mailing to the general surgeon members of the Society of Laparoendoscopic Surgeons, an international multidisciplinary laparoendoscopic society, was performed (mailing size = 1680).

RESULTS

Nine hundred and ninety-three surgeons responded (60%). Across all demographic variables, 60% of respondents performed approximately 27% of their hernia repairs laparoscopically (40% of respondents did not perform LHR). Surgeon age less than 45 was the only demographic characteristic that predicted the likelihood to perform LHR (p < 0.0001) and the percentage of hernias repaired laparoscopically (p < 0.005). Most respondents felt that the presence of bilateral hernias (73%) or a recurrent hernia (74%) were indications for LHR. Eighty-nine percent of respondents felt that LHR would still be performed 20 years from now. Surgeons expressed concerns regarding increased cost, the need for more anesthesia, and a lack of long-term follow-up for LHR.

CONCLUSIONS

Only surgeon age predicted the likelihood of a surgeon performing LHR or the percentage of hernias that would be repaired laparoscopically.
