Do open repair and different laparoscopic techniques in pediatric inguinal hernia repairs affect the vascularization of testes?

PurposeThe aim of this study was to evaluate, using Doppler ultrasonography, the effects of different hernia repair techniques on testicular perfusion in the pediatric age group.MethodsThis study was based on a prospective clinical trial of 72 pediatric patients over 2 years of age with unilateral inguinal hernia. They were operated on using 1 of 3 different techniques. Group 1 included 26 patients who were treated with a conventional open hernia repair technique. Group 2 included 22 patients who underwent Schier intracorporeal laparoscopic suture technique. Group 3 included 24 patients who underwent the laparoscopic partial excision and purse-string technique described by Montupet. In all cases, blood flow index of the centripetal and capsular arteries of the testes, including peak systolic velocity (PSV) and resistivity index (RI), were examined by using Doppler ultrasound preoperatively and early and late postoperatively.ResultThe conventional open technique group (group 1) had transient temporary changes in PSV and RI values compared with preoperative findings; however, these changes were not statistically significant. No such changes were observed in the 2 laparoscopic groups.ConclusionNeither conventional open nor laparoscopic hernia repair techniques impaired testes vascularization. Surgical manipulations performed using the conventional open repair technique caused transient, but not significant, changes in PSV and RI values.     

Do the manipulations in pediatric inguinal hernia operations affect the vascularization of testes?

Purpose

The aim of this study is to evaluate the effect of manipulations performed in inguinal hernia operations on testicular perfusion, in pediatric age group using Doppler ultrasonography (DUS).

Methods

In this prospective clinical trial, 51 boys who underwent elective inguinal hernia repair were examined before the operation and in early-late postoperative periods. Blood flow indices of centripetal and capsular arteries including peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistivity index (RI) were examined by DUS.

Results

There was a statistically significant increase in early postoperative PSV and RI values compared with preoperative findings. These values turned to normal in late postoperative period. The increase in early and decrease in late postoperative EDV values were not statistically significant compared to preoperative findings.

Conclusions

The surgical manipulations performed in inguinal hernia operations in children cause transient changes in testes vascularization in early postoperative period but turns to normal late postoperatively.     

Undescended testes: Does age at orchiopexy affect survival of the testis?

Purpose

The optimal age at which to perform orchiopexy for cryptorchidism has long been debated. The aim of this study was to determine if age at orchiopexy affected testicular atrophy.

Methods

A retrospective review of patients undergoing orchiopexy from 2000 to 2010 was conducted. An individual testis, rather than patient, was used as the dependent variable. A total of 349 testicles from 1126 charts (ICD-9 = 752.51) were identified. Primary study outcome was testicular survival without atrophy.

Results

Mean follow up for the study was 25 months. There was postoperative atrophy in 27 testes (7.7%). Intraabdominal testicle was independently associated with increased postsurgical atrophy (p < 0.0001). The odds of postsurgical atrophy were 15.66 times higher for an abdominal vs. inguinal location (95% CI: 5.5–44.6). Testicular atrophy was highest for orchiopexy at ages 13–24 months (n = 16 of 133, 12%) vs. those less than 13 months (n = 3 of 64, 5%), and those greater than 24 months (n = 8 of 152, 5%) (p = 0.0024). After adjusting for location, age was not statistically significant with postsurgical atrophy (p = 0.055).

Conclusions

From this study we conclude that there is no increase in testicular atrophy in patients less than 13 months.     

Laparoscopic preperitoneal mesh repair or tension-free mesh plug technique? A prospective study of 471 patients with 543 inguinal hernias.

OBJECTIVE: To compare two modem mesh-based "tension free" hernioplasties, laparoscopic repair and mesh plug technique. DESIGN: Prospective, non-randomised study. SETTING: Two major medical centres, Greece. SUBJECTS: 471 patients with 543 inguinal hernias. INTERVENTION: Patients entering the study were treated in two major medical centres either by laparoscopic repair under general anaesthesia (n = 237) in hospital A, or by insertion of a mesh plug under monitored local, epidural, or spinal anaesthesia (n = 234) in hospital B. Patients with known bilateral inguinal hernias, femoral hernias, and those with both inguinal hernias and cholelithiasis were encouraged to undergo laparoscopic repair. MAIN OUTCOME MEASURES: Operative time, hospital mortality, morbidity and length of stay, costs, time to return to work, and recurrence rate. RESULTS: The median operative time for laparoscopic repair was significantly longer (57 compared with 33 minutes, p < 0.001). Laparoscopic repair was more costly (1,200 US dollars compared with 500), and technically more demanding than insertion of a mesh plug. The median postoperative hospital stay, consumption of narcotic analgesics, and return to full work and heavy activities were similar in the two groups, whereas light activities were started earlier after plug repair [5.4 (2.4) compared with 3.4 (1.5) hours, p < 0.0001]. There were 6 recurrences in the laparoscopic group and 1 in the plug group. CONCLUSIONS: Mesh plug insertion is faster, cheaper, technically easier, does not require general anaesthesia, and is suitable to be done by surgeons as part of their general practice without special instruments and by junior surgeons. Plug repair resulted in fewer short or long term complications and reduced the recurrence rate.     

Laparoscopic insertion of ventriculoperitoneal shunts in pediatric patients — A retrospective cohort study

IntroductionVentriculoperitoneal shunts (VPSs) are the mainstay of treatment of hydrocephalus but have frequent complications including shunt failure and infection. There has been no comparison of laparoscopic versus open primary VPS insertion in children. We hypothesized that laparoscopic VP shunt insertion may improve patient outcomes.MethodsA prospectively-maintained, externally-validated database of pediatric patients who underwent VPS insertion at a single center between 2012 and 2016 was reviewed. Outcomes including subsequent revisions, shunt infections, operative time, and hospital stay between open and laparoscopic groups were compared.Results210 patients underwent VPS insertion — 41 laparoscopically and 169 open. Operative time was longer for laparoscopic insertions. There was no difference in shunt infections, complications or length of stay. There was no difference between overall revisions or in confirmed peritoneal obstructions in the laparoscopic (12%) versus open VPS insertions (5%), p = 0.13.ConclusionsThis first cohort analysis of laparoscopic versus open VPS insertion in pediatric patients indicates no difference in confirmed peritoneal obstructions. With increasing use of laparoscopic placement in some centers, it remains important to elucidate if there is a subset of pediatric patients who might benefit from this technique; possible candidates may be those who are overweight/obese or have had previous intra-abdominal surgery.Level of evidenceIII — Retrospective cohort study.     

Laparoscopic incisional hernia repair: are transfascial sutures necessary? A review of the literature

Background Laparoscopic repair of incisional and ventral hernias is rapidly becoming more commonplace in the armamentarium of general surgeons. Its utility and low recurrence rates make it a very attractive option. As with all newer procedures, controversies exist with this approach. One significant aspect is the method of fixation for the biomaterial. Most authors add the use of transfascial sutures. Others, in the minority, do not. Methods A literature search using Medline and PubMed was used to evaluate the best practice for fixation in laparoscopic incisional and ventral hernia repair. Results This review of the current literature (including comparative series) seems to show that the recurrence rate is approximately 4% with the use of sutures and 1.8% without their use. However, these data do not show that there is tremendous variation in the method and manner of placing transfascial sutures or that long-term follow-up evaluation is inadequate in most series. No firm conclusions can be drawn about whether it is detrimental to omit the use of transfascial sutures. Conclusions On the basis of this review, a larger overlap of the prosthesis (5 vs 3 cm) is necessary if sutures are not used. If sutures are used, they should be placed no more than 5 cm apart. Prospective randomized trials with and without of transfascial sutures using a consistent biomaterial are necessary to settle this issue.     

Robotic inguinal hernia repair: Is it a new era in the management of inguinal hernia?

ObjectiveWe compared outcomes of elective inguinal hernia repair performed at one institution by three approaches: robotic-assistance, laparoscopic, and open.MethodsCharacteristics of the patients, the hernia and the procedures performed during 2014–2016 were accessed from patient electronic medical files of 137 elective inguinal hernia repairs. 24 surgeries were robotic-assisted, 16 laparoscopic and 97 open repairs.ResultsDistributions of age, sex and BMI did not differ between the groups. Bilateral repair was more common in the robotic (70.8%) than the laparoscopic (50.0%) and open groups (12.4%) (p < 0.001). Direct hernias were more common in the open (45.4%) than the robotic (20.8%) and laparoscopic (12.5%) groups (p < 0.001). Only 3 hernias were inguinoscrotal, all in the robotic group. The median operation times were 44.0, 79.0 and 92.5 min for the open, laparoscopic and robotic methods, respectively (p < 0.001). Among the unilateral repairs, the median operative times were the same for the robotic and laparoscopic procedures, 73 min, and less for the open procedures, 40 min. The proportion of patients hospitalized for 2–3 days was higher for open repair (13.4% vs. 6.2% and 0% for laparoscopic and robotic), but this difference was not statistically significant. The median maximal postoperative pain according to a 0-10-point visual analogue score was 5.0, 2.0 and 0 for open, laparoscopic and robotic procedures, respectively (p < 0.001).ConclusionsThis report demonstrated the safety and feasibility of robotic-assisted inguinal hernia repair.     

Is minilaparoscopic inguinal hernia repair feasible? A preliminary experience

INTRODUCTION: Laparoscopy has rapidly emerged as the preferred surgical approach to a number of different diseases because it allows for a correct diagnosis and proper treatment. It seems to be moving toward the use of mini-instruments (5 mm or less in diameter). The aim of this paper is to illustrate retrospectively the results of an initial experience of minilaparoscopic transabdominal preperitoneal (miniTAPP) repair of groin hernia defects performed at two institutions. MATERIALS AND METHODS: Between February 2000 and December 2003, a total of 303 patients (mean age, 45 years) underwent a miniTAPP procedure: 213 patients (70.2%) were operated on bilaterally and 90 (28.7%) for a unilateral defect, with a total of 516 hernia defects repaired. The primary endpoint was the feasibility rate for miniTAPP. The secondary endpoint was the incidence of mini-TAPP-related complications. RESULTS: No conversions to laparoscopy or an anterior open approach were required. There were no major complications, while minor complications ranged as high as 0.3%. CONCLUSION: While limited by its retrospective design, the present study indicates that the minilaparoscopic approach to groin hernia repair is safe and effective, making miniTAPP a challenging alternative to laparoscopy in the approach to groin hernia repair.     

Does resident post graduate year influence the outcomes of inguinal hernia repair?

INTRODUCTION: We evaluated the effect of the postgraduate medical education level (PGY) of surgery residents on recurrence of inguinal hernia, complications, and operative time. METHODS: Post hoc analysis was performed on prospectively collected data from a multicenter Veterans Affairs (VA) cooperative study. Men were randomly assigned to open or laparoscopic inguinal hernia repairs with mesh. Surgery residents performed repairs with designated attending surgeons present throughout all procedures. PGY level of the resident was recorded for each procedure. All patients were followed for 2 years for hernia recurrence and complications. PGY levels were grouped as follows: group I = PGY 1 and 2; group II = PGY 3; group III = PGY >/= 4; rates of recurrence, complications and mean operative time were compared. RESULTS: A total of 1983 patients underwent hernia repair. group III residents had significantly lower recurrence rates for open repairs when compared with group I (adjusted odds ratio = 0.24, 95% confidence interval [CI], 0.06, 0.997). The recurrence rate was similar among the groups for laparoscopic repair (P > 0.05) Complication rates were not different for either repair (P > 0.05). Mean operative time was significantly shorter for group III compared with group I for both open (-6.6 minutes; 95% CI, -11.7, -1.5) and laparoscopic repairs (-12.9 minutes; 95% CI, -19.8, -6.0) and between group II and group I for laparoscopic repair (-15.0; 95% CI, -24.3, -5.7). CONCLUSIONS: Despite the presence of an attending surgeon, open hernia repairs performed by junior residents were associated with higher recurrence rates than those repaired by senior residents. Lower resident level was associated with increased operative time for both open and laparoscopic repair.     

Laparoscopic repair of hiatus hernia: Does mesh type influence outcome? A meta-analysis and European survey study

Background

Synthetic mesh (SM) has been used in the laparoscopic repair of hiatus hernia but remains controversial due to reports of complications, most notably esophageal erosion. Biological mesh (BM) has been proposed as an alternative to mitigate this risk. The aim of this study is to establish the incidence of complications, recurrence and revision surgery in patients following suture (SR), SM or BM repair and undertake a survey of surgeons to establish a perspective of current practice.

Methods

An electronic search of EMBASE, MEDLINE and Cochrane database was performed. Pooled odds ratios (PORs) were calculated for discrete variables. To survey current practice an online questionnaire was sent to emails registered to the European Association for Endoscopic Surgery.

Results

Nine studies were included, comprising 676 patients (310 with SR, 214 with SM and 152 with BM). There was no significant difference in the incidence of complications with mesh compared to SR (P = 0.993). Mesh significantly reduced overall recurrence rates compared to SR [14.5 vs. 24.5 %; POR = 0.36 (95 % CI 0.17–0.77); P = 0.009]. Overall recurrence rates were reduced in the SM compared to BM groups (12.6 vs. 17.1 %), and similarly compared to the SR group, the POR for recurrence was lower in the SM group than the BM group [0.30 (95 % CI 0.12–0.73); P = 0.008 vs. 0.69 (95 % CI 0.26–1.83); P = 0.457]. Regarding surgical technique 503 survey responses were included. Mesh reinforcement of the crura was undertaken by 67 % of surgeons in all or selected cases with 67 % of these preferring synthetic mesh to absorbable mesh. One-fifth of the respondents had encountered mesh erosion in their career.

Conclusions

Both SM and BM reduce rates of recurrence compared to SR, with SM proving most effective. Surgical practice is varied, and there remains insufficient evidence regarding the optimum technique for the repair of hiatal hernia.

     

Laparoscopic management of mesh migration into urinary bladder following laparoscopic totally extraperitoneal inguinal hernia repair—A case report

Introduction and importanceMesh migration into urinary bladder is one of the rare complications following inguinal hernia repair (Laparoscopic/Open). On reviewing the literature, erosion of mesh following inguinal hernia repair has been into the urinary bladder in most of the cases, and the erosion may occur as early or late complication. It may occur as a result of improper suturing, inadequate fixation or foreign body reaction. The most common presentation is recurrent urinary tract infection and haematuria and may mimic bladder malignancy.Case presentationA 38-year male presented with recurrent UTI and mimicked to have bladder malignancy on CT scan. On Cystoscopy, mesh along with tackers is visualized within the bladder lumen. A diagnosis of Mesh migration into bladder following laparoscopic inguinal hernia repair was made. The Patient underwent Complete laparoscopic removal of mesh with partial cystectomy, per urethral and suprapubic catheter were placed. The patient made a good recovery without any post-operative complications. On follow-up, Patient underwent Fluoroscopy to look for urinary leakage, and suprapubic catheter removal was done. Patient is asymptomatic on follow-up.Clinical discussionMesh migration into bladder is one the rare complications following laparoscopic hernia repair. Proper preoperative evaluation is necessary to determine whether mesh is free floating in the bladder lumen or adherent to bladder wall. This will help in deciding the surgical technique for route of extraction.ConclusionA case of mesh migration into the bladder can be easily managed by laparoscopic TAPP approach and it is better approach compared to other techniques.
