Prosthetic mesh repair of large and recurrent diaphragmatic hernias

Background Laparoscopic repair of large paraesophageal hernias (PEH) is associated with significant recurrence rates. Use of prosthetic mesh to complete tension-free repair of the hiatus has been suggested to decrease the recurrence rate. Methods Fifty-nine patients with large (n = 44) or recurrent (n = 15) PEH were operated on via the laparoscopic approach with the use of prosthetic mesh. Patients were followed with office visits and phone interviews. All patients were referred for barium studies. Data analysis included all patients, including conversions, on an intention-to-treat basis. Results Followup was completed in 56 (95%) patients. Mean followup time was 28.4 months. Forty patients (74%) had significant relief of all symptoms. Barium studies were performed in 45 patients (80.3%), including all symptomatic patients. Fifteen patients (33%) had a small sliding hernia, six (13.3%) had recurrent PEH, and four (8.8%) had narrowing of the gastroesophageal junction. Most patients with small hiatal hernias were symptomatic (60%). All responded to medical treatment. Conclusions Laparoscopic repair of large PEH with reinforcement mesh is feasible and safe with excellent short-term results. Long-term followup shows a low PEH recurrence requiring reoperation, but a significant number of patients develop symptomatic recurrent small hiatal hernias that can be managed nonoperatively.

Evaluation of acellular human dermis reinforcement of the crural closure in patients with difficult hiatal hernias

Background Biologic prosthetics may circumvent mesh-related complications at the esophageal hiatus by becoming remodeled by native cells. We present our experience with acellular human dermal matrix in the repair of difficult hiatal hernias (HH). Methods Records of 17 patients who underwent laparoscopic HH repair using acellular human dermis to buttress the crural closure were analyzed. Hernias were paraesophageal (PEH) in 12 patients, large type 1 in 1 patient, and recurrent after prior HH repair in 4 patients. Barium swallow (BAS) was obtained 6–12 months after surgery. (Data are presented as mean ± standard deviation.) Results Mean patient age was 65 ± 12 years and BMI was 31 ± 4. Mean gastroesophageal (GE) junction distance above the diaphragm in the PEHs was 4.9 ± 1.5 cm; 9 of 12 patients with PEH had more than 50% of the stomach in the chest. Mean operating time was 273 ± 48 min. Average hiatal defect size was 4.7 × 2.7 cm, with 4.2 ± 1.2 sutures used to close the crura. Nissen fundoplication was performed in all patients, esophageal lengthening in four patients, and anterior gastropexy in three patients. Mean hospital length of stay (LOS) was 2.3 ± 0.8 days. Mean followup was 14.4 ± 4.4 months. Postoperatively, only one (6%) patient had heartburn/regurgitation, one (6%) had mild dysphagia, and two (12%) take proton pump inhibitors. Followup BAS at 10.3 ± 4.9 months after surgery showed small recurrent hernias in two patients (12%), but only one was symptomatic. In addition, there was one symptomatic failure of a redo Nissen in an obese patient. Reoperative gastric bypass 15 months later showed an intact crural closure with a remodeled buttress site. Conclusions Acellular human dermal matrix may be an effective method to buttress the crural closure in patients with large hiatal hernias. Longer followup in larger numbers of patients is needed to assess the validity of this approach. Presented at the April 28, 2006 SAGES Meeting, Dallas, TX     

Laparoscopic repair of large hiatal hernia with polytetrafluoroethylene

Background: Several studies have shown that large hiatal hernias are associated with a high recurrence rate. Despite the problem of recurrence, the technique of hiatal herniorrhaphy has not changed appreciably since its inception. In this 3-year study we have evaluated laparoscopic hiatal hernia repair in individuals with a hernia defect greater than 8 cm in diameter. Methods: A series of 35 patients with sliding or paraesophageal hiatal hernias was prospectively randomized to hiatal hernia repair with (n= 17) or without (n= 18) polytetrafluoroethylene (PTFE). All patients had an endoscopic and radiographic diagnosis of large hiatal hernia. Both repairs were performed by using interrupted stitches to approximate the crurae. In the group randomized to repair with prosthesis, PTFE mesh with a 3-cm ``keyhole' was positioned around the gastroesophageal junction with the esophagus through the keyhole. The PTFE was stapled to the diaphragm and crura with a hernia stapler. Results: Patients were followed with EGD and esophagogram at 3 months postoperatively, and with esophagogram every 6 months thereafter. Individuals with PTFE had a longer operation time, but the 2-day hospital stay was the same in both groups. The cost of the repair was $1050 ± $135 more in the group with the prosthesis. There were two complications (1 pneumonia, 1 urinary retention) in the group repaired with PTFE and one complication (pneumothorax) in the group without prosthesis. The group without PTFE was notable for three (16.7%) recurrences within the first 6 months of surgery. Conclusion: On the basis of these preliminary results it appears that repair with PTFE may confer an advantage, with lower rates of recurrence in patients with large hiatal hernia defects.

Is a barium swallow complementary to endoscopy essential in the preoperative assessment of laparoscopic antireflux and hiatal hernia surgery?

Background Barium swallow is considered essential in the preoperative assessment of gastroesophaeal reflux disease and hiatal hernias. The objective of this study was to investigate the effective value of a barium swallow if complementary to the commonly recommended endoscopy before laparoscopic antireflux and hiatal hernia surgery. Methods We prospectively evaluated 40 consecutive patients who were tested with preoperative barium swallow and endoscopy before laparoscopic surgery for gastroesophageal reflux disease and/or symptomatic hiatal hernia. Results regarding the presence and the type of hiatal hernia found by barium swallow and endoscopy were correlated with the intraoperative finding as the reference standard. Results Intraoperative findings revealed 21 axial, 7 paraesophageal, and 12 mixed hiatal hernias. Barium swallow and endoscopy allowed the diagnosis of hiatal hernia in 75% and 97.5%, respectively (p = 0.003). The correct classification of hiatal hernia was confirmed in 50% by barium swallow and 80% by endoscopy (p = 0.005). Conclusions Although barium swallow is recommended as an important diagnostic tool in the workup before surgical antireflux and hiatal hernia therapy, our results suggest that if mandatory endoscopy is performed preoperatively, a barium swallow does not provide any further essential information. It seems that barium swallow can be omitted as a basic diagnostic test before primary laparoscopic antireflux and hiatal hernia surgery.     

Endoscopic total extraperitoneal repair of primary and recurrent inguinal hernias

Background: In most reports different techniques have been described for combinations of primary and recurrent hernias. The aim of this study was to investigate and compare the results of endoscopic total extraperitoneal repair (TEP) of primary and recurrent inguinal hernias. Methods: From January 1993 to July 1995, 221 patients with an unilateral inguinal hernia (186 primary and 35 recurrent) underwent TEP repair. Follow-up, including physical examination, was performed at regular 3-month intervals. Results: The mean operation time was 37.6 min. Minor perioperative complications occurred in 23 cases. Conversion was required for 16 patients (7.2%). Postoperative complications were reported for 11.7% of the patients. Hospital stay was short. Mean follow-up was 40.4 months. The recurrence rate was 3.2% for primary hernias and 20% for recurrent hernias. Conclusions: This study confirms the preliminary success of TEP for primary inguinal hernia repair, as previously reported. The high recurrence rate after endoscopic repair of recurrent hernias needs to be studied further. Received: 3 December 1997/Accepted: 7 May 1998     

360° laparoscopic fundoplication with tension-free hiatoplasty in the treatment of symptomatic gastroesophageal reflux disease

Background: Since laparoscopic Nissen fundoplication was first described by Cuschieri in 1989 and later by Dallemagne in 1991, this procedure has been widely employed for the treatment of symptomatic gastroesophageal reflux disease (GERD) and/or hiatal hernia. However, a relatively high incidence (7–11%) of intrathoracic Nissen valve migration/paraesophageal hernia following laparoscopic fundoplication has recently been reported. Methods: Between November 1992 and August 1995, 65 consecutive patients with severe GERD and/or hiatal hernia underwent laparoscopic 360° fundoplication. In nine of these 65 (13.8%) patients, an intrathoracic Nissen valve migration had occurred within 4 months. Six of these patients were symptomatic and were again submitted to the laparoscopic intervention. Videotapes of both the first and second operation were reviewed. In all cases, it was apparent that, at the first operation, closure by stitches of the hiatus was under tension, and at the second operation, the muscle fibers of the right crus were disrupted, probably due to the tension between the suture margins during the inspiratory movements of the diaphragm. These findings prompted us to perform an effective tension-free closure of the hiatus. A polypropylene mesh (3 × 4 cm) was placed on the hiatus behind the esophagus and fixed with eight metallic agraphes (2 + 2 on the superior edge and 2 + 2 on the lateral sides of the right and left cruses). Results: Between August 1995 and February 1998, the technique, complete with 360° fundoplication, was used for 67 patients with GERD. At mean follow-up of 22.5 months (range, 1–30), there was no evidence of postoperative paraesophageal hernia or complications related to the use of the mesh. Conclusions: This tension-free hiatoplasty seems to be an effective solution to prevent postoperative paraesophageal hernia in patients undergoing antireflux laparoscopic surgery. However, longer follow-up is still needed. Received: 9 July 1998/Accepted: 19 April 1999     

Laparoscopic mesh hiatoplasty for paraesophageal hernias and fundoplications

Background Little grade A medical evidence exists to support the use of prosthetic material for hiatal closure. Therefore, the authors compiled and analyzed all the available literature to determine whether the use of prosthetic mesh in hiatoplasty for routine laparoscopic fundoplications (LF) or for the repair of large (>5 cm) paraesophageal hernias (PEH) would decrease recurrence. Methods A literature search was performed using an inclusive list of relevant search terms via Medline/PubMed to identify papers (n = 19) describing the use of prosthetic material to repair the crura of patients undergoing laparoscopic PEH reduction, LF, or both. Results Case series (n = 5), retrospective reviews (n = 6), and prospective randomized (n = 4) and nonrandomized (n = 4) trials were identified. Laparoscopic procedures (n = 1,368) were performed for PEH, gastroesophageal reflux disease (GERD), hiatal hernia, or a combination of the three. Group A (n = 729) had primary suture repair of the crura, and group B (n = 639) had repair with either interposition of mesh to close the hiatus or onlay of prosthetic material after hiatal or crural closure. The use of mesh was associated with fewer recurrences than primary suture repair in both the LF and PEH groups. The mean follow-up period did not differ between the groups (20.7 months for group A vs. 19.2 months for group B). None of the papers cited any instance of prosthetic erosion into the gastrointestinal tract. Conclusions The current data tend to support the use of prosthetic materials for hiatal repair in both routine LF and the repair of large PEHs. Longer and more stringent follow-up evaluation is necessary to delineate better the safety profile of mesh hiatoplasty. Future randomized trials are needed to confirm that mesh repair is superior to simple crural closure.     

A randomized, controlled, clinical study of laparoscopic vs open tension-free inguinal hernia repair

Background: The aim of this prospective, randomized, controlled clinical study was to compare laparoscopic transabdominal preperitoneal (TAPP) hernia repair with a standard tension-free open mesh repair (open). Methods: A total of 108 low-risk patients with unilateral (primary or recurrent) or bilateral hernias were randomized to TAPP (group 1 = 52 cases) or open (group 2 = 56 cases). The outcome measures included operating time, complications, postoperative pain, return to normal activity, operating theater costs, and recurrences. Results: The mean operative time was longer for the TAPP than for the open group only in unilateral primary hernias. At rest, the median Visual Analog Scale (VAS) score was higher for group 1 than group 2 at 48 h postoperatively. Mild to discomforting pain in the inguinal region after 7 days, night pain after 30 days, and inguinal hardening after 3 months were more frequent in group 2 than group 1. No significant differences were observed in return to normal activities between the groups. One hernia recurrence was observed after 1 month in group 1. TAPP was significantly more expensive than open. Conclusions: TAPP was associated with less postoperative pain than open. The increase in operating theater costs, however, was dramatic and was not compensated by shorter time away from work. TAPP should not be adopted routinely unless its costs can be drastically reduced. Received: 10 June 1997/Accepted: 6 October 1997     

Laparoscopic ventral hernia repair

Introduction: Effective surgical therapy for ventral and incisional hernias is problematic. Recurrence rates following primary repair range as high as 25–49%, and breakdown following conventional treatment of recurrent hernias can exceed 50%. As an alternative, laparoscopic techniques offer the potential benefits of decreased pain and a shorter hospital stay. This study evaluates the efficacy of the laparoscopic approach for ventral herniorrhaphy. Methods: A retrospective review was performed for 100 consecutive patients with ventral hernias who underwent laparoscopic repair at our institutions between November 1995 and May 1998. All patients who presented during this period and were candidates for a mesh hernia repair were treated via an endoscopic approach. Results: One hundred patients underwent a laparoscopic ventral hernia repair. There were 48 men and 52 women. The patients were typically obese, with a mean body mass index (BMI) of 31 kg/m². Each had undergone an average of 2.5 (range; 0–8) previous laparotomies. Forty-nine repairs were performed for recurrent hernias. An average of two patients (range; 1–7) had previously failed open herniorhaphies; in 20 cases, intraabdominal polypropylene mesh was present. There were no conversions to open operation. The mean size of the defects was large at 87 cm² (range; 1–480). In all cases, the mesh (average, 287 cm²) was secured with transabdominal sutures and metal tacks or staples. Operative time and estimated blood loss averaged 88 min (range; 18–270) and 30 cc (range; 10–150). Length of stay averaged 1.6 days (range; 0–4). There were 12 minor and (two) major complications: cellulitis of the trocar site (two), seroma lasting >4 weeks (three), postoperative ileus (two), suture site pain > 2 weeks (two), urinary retention (one), respiratory distress (one), serosal bowel injury (one), and skin breakdown (one) and bowel injury (one). Both of the latter complications required mesh removal. With an average follow-up of 22.5 months (range; 7–37), there have been (three) recurrences. Conclusion: The laparoscopic approach to the repair of both primary and recurrent ventral henias offers a low conversion rate, a short hospital stay, and few complications. At 23 months of follow-up, the recurrence rate has been 3%. Laparoscopic repair should be considered a viable option for any ventral hernia.

Mesh configurations in laparoscopic extraperitoneal herniorrhaphy

Background: Laparoscopic total extraperitoneal (TEP) hernia repair utilizes slit mesh that is placed around the spermatic cord to secure the prosthesis and prevent recurrence. Because of concern that encircling of the cord might increase pain and morbidity, we compared patients with mesh repairs using encircled and nonencircled techniques. Methods: The 191 male patients who underwent bilateral TEP repairs were divided into three groups. In 100 consecutive patients (group A), the slit mesh was closed around both spermatic cords; in 56 patients (group B), the slit mesh was tucked under the spermatic cords but not closed; in 35 consecutive patients (group C), the slit was closed around one cord and tucked under the other, in a randomized fashion. Results: The groups had similar operative times (A: 83 ± 25 min; B: 79 ± 21; C; 77 ± 24), use of pain medication (A: 2.7 ± 2.5 days; B: 2.4 ± 1.9; C: 3.1 ± 2.4), and recovery before return to work (A: 7.9 ± 7.0 days; B: 8.2 ± 6.1; C: 6.7 ± 4.8). The incidence of indirect hernias was similar in all groups. Complication rate was 20% in A, 20% in B, and 14% in C (p= NS). Chronic pain was more frequent in A (A: 6, B: 0, p= 0.06). In group C, fluid collections were more common on the closed side (closed: 3, tucked: 0; p= 0.08). There were no recurrences in any group. Conclusions: Closing the slit around the spermatic cord in laparoscopic inguinal hernia repair is not essential for prevention of early recurrence. Fluid collections tended to be more frequent when the mesh was closed around the cord, and chronic pain was more frequent in the group with closed mesh bilaterally.

Incidence of incipient contralateral hernia during laparoscopic hernia repair

Background: In addition to its well-known benefits of decreased postoperative pain and shorter recovery time, laparoscopic hernia repair has the major advantage of allowing the surgeon to explore the side contralateral to the clinically diagnosed hernia. The purpose of this study was to evaluate the incidence of incipient unsuspected contralateral hernia during totally extraperitoneal (TEP) laparoscopic inguinal herniorrhaphy and to analyze the risks and benefits of identifying these hernias at the time of the initial surgery. Methods: We did a retrospective review of the charts of all of the 724 male patients who underwent laparoscopic TEP repair of 958 groin hernias between September 1991 and September 1999. The initial clinical impression of the existence of unilateral or bilateral hernias was noted and compared to our operative findings. The same surgeon performed all the repairs. Exploration of the contralateral side was performed in a systematic fashion. A second mesh prosthesis was placed if a contralateral hernia was found. Results: Bilateral hernia repair was performed on 234 patients (32.3%). In 62 of them (11.2%), the contralateral hernia was diagnosed only at the time of the procedure. Operative time ranged from 14 to 185 min (median, 38.6). The operative time for the contralateral exploration ranged from 2 to 5 min (median, 2.8). The rate of complications was 4.1%, but no complications were directly related to the exploration of the asymptomatic side. Conclusion: Our study shows that a large number of inguinal hernias are undiagnosed by physical examination (11.2%). Systematic contralateral exploration using the TEP approach is safe and does not greatly increase the operative time. Early identification and repair of a contralateral hernia obviates the need for reoperation, reduces overall costs to the health care system, and eliminates any further work loss for the patient.

Prosthetic reinforcement of posterior cruroplasty during laparoscopic hiatal herniorrhaphy

Symptomatic gastroesophageal reflux after Nissen fundoplication may occur if the wrap herniates into the thorax. In an attempt to prevent recurrent hiatal hernia we employed polytetrafluoroethylene (PTFE) mesh reinforcement of posterior cruroplasty during laparoscopic Nissen fundoplication and hiatal herniorrhaphy. Three patients with symptomatic gastroesophageal reflux and a large (≥8 cm) hiatal defect underwent laparoscopic posterior cruroplasty and Nissen fundoplication. The cruroplasty was reinforced with a PTFE onlay. No perioperative complications occurred, and in follow-up (≤11 months) the patients are doing well. When repairing a large defect of the esophageal hiatus during fundoplication, the surgeon may consider reinforcement of the repair with PTFE mesh. Received: 5 March 1996/Accepted: 3 June 1996     

Open or laparoscopic preperitoneal mesh repair for recurrent inguinal hernia?

Background: Giant prosthetic reinforcement of the visceral sac (GPRVS), an open preperitoneal mesh repair, is a very effective groin hernia repair. Laparoscopic transabdominal preperitoneal repair (TAPP), based on the same principle, is expected to combine low recurrence rates with minimal postoperation morbidity. Methods: Seventy-nine patients with 93 recurrent and 15 concomitant primary inguinal hernias were randomized between GPRVS (37 patients) and TAPP (42 patients). Operating time, complications, pain, analgesia use, disability period, and recurrences were recorded. Results: Mean operating time was 56 min with GPRVS versus 79 min with TAPP (p < 0.001). Most complications were minor, except for a pulmonary embolus and an ileus, both after GPRVS. Patients experienced less pain after a laparoscopic repair. Average disability period was 23 days with GPRVS versus 13 days with TAPP (p= 0.03) for work, and 29 versus 21 days, respectively (p= 0.07) for physical activities. Recurrence rates at a mean follow-up of 34 months were 1 in 52 (1.9%) for GPRVS versus 7 in 56 (12.5%) for TAPP (p= 0.04). Hospital costs in U.S. dollars were comparable, with GPRVS at $1,150 and TAPP at $1,179. Conclusions: Laparoscopic repair of recurrent inguinal hernia has a lower morbidity than GPRVS. However, laparoscopic repair is a difficult operation, and the potential technical failure rate is higher. With regard to recurrence rates, the open preperitoneal prosthetic mesh repair remains the best repair. Received: 14 April 1998/Accepted: 28 May 1998     

Repair of post–bariatric surgery,recurrent, and de novo hiatal hernias improves bloating,abdominal pain,regurgitation, and food intolerance

BackgroundPost–bariatric surgery hiatal hernias are associated with a cluster of symptoms, including bloating (nausea/vomiting or fullness), abdominal pain, regurgitation, and food intolerance or dysphagia (BARF).ObjectivesTo report the short-term outcomes of repairing post–bariatric surgery hiatal hernias in patients with BARF.SettingLarge, multispecialty group practice with university affiliation.MethodsWe reviewed the records of all consecutive patients who underwent repair of post–bariatric surgery hiatal hernias (2012–2020). Data are shown as means ± standard deviations.ResultsWe repaired hiatal hernias in 52 patients (age, 57 ± 10 yr), 4 ± 3 years post sleeve gastrectomy (SG; n = 27), 11 ± 6 years following Roux-en-Y gastric bypass (RYGB; n = 24), and 11 years post duodenal switch with SG (DS-SG; n = 1). Diagnoses were made by upper gastrointestinal contrast study (80%), computed tomography (70%), and/or endoscopy (56%). Hernias in patients with SG were repaired by a posterior cruroplasty after reducing the neo-stomach into the abdomen (n = 11 SG patients; n = 1 DS-SG patient) or converting the SG to RYGB (n = 16). All 24 RYGB patients underwent hernia repair similarly. At 12 ± 10 months of follow-up, dysphagia or regurgitation improved in >80% of patients; nausea, vomiting, or abdominal pain improved in 70% of patients; and heartburn persisted in 56% of patients. Subsequent recurrent hernias that required operative repair developed in 3 patients.ConclusionsHiatal hernias containing the neo-stomach present earlier after SG than RYGB. The diagnosis can be made with a combination of imaging studies and endoscopy. Repair of post–bariatric surgery hiatal hernias markedly improves symptoms of BARF in most patients.     

Laparoscopic extraperitoneal inguinal hernia repair with spinal anesthesia and nitrous oxide insufflation

Background: Laparoscopic repair of inguinal hernia is traditionally performed under general anesthesia mainly because of the adverse effects that carbon dioxide pneumoperitoneum has on awake patients. Since a mandatory use of general anesthesia for all hernia repairs is questionable, the feasibility of laparoscopic extraperitoneal herniorraphy using spinal anesthesia combined with nitrous oxide insufflation was investigated. Methods: Over a 4-month period, February to May 1998, we performed 35 consecutive total extraperitoneal inguinal hernia procedures (24 unilateral, 11 bilateral) using spinal anesthesia and nitrous oxide extraperitoneal gas. Data on operative findings, self-reported operative and postoperative pain and discomfort (visual analog pain scale), procedure-related hemodynamics, and complications were collected prospectively. Results: All 35 procedures were completed laparoscopically without the need to convert to general anesthesia. Mean operative time was 39 ± 7 min for unilateral hernia and 65 ± 10 min for bilateral hernia. Incidental peritoneal tears occurred in 22 patients (63%) resulting in nitrous oxide pneumoperitoneum, which was well tolerated. The patients remained hemodynamically stable throughout the procedure, and operative conditions and visibility were excellent. Complications at a mean of 4 months after the procedure included seven uninfected seromas (20%), three patients with transient testicular pain, and one (3%) recurrence. Conclusions: Laparoscopic total extraperitoneal hernia repair can be safely and comfortably performed using spinal anesthesia with extraperitoneal nitrous oxide insufflation gas. This method provides a good alternative to general anesthesia. Received: 17 February 1999/Accepted: 1 July 1999     

Technique and early results of outpatient laparoscopic mesh onlay repair of ventral herniasrid=""id=""Presented to the Canadian Association of General Surgeons at the 67th Annual Meeting of the Royal College of Physicians and Surgeons of Canada, Toronto, Ontario, September 1998

Background: This report describes the technique and early results of a simple outpatient laparoscopic ventral hernia repair. Methods: Data were gathered prospectively for all laparoscopic ventral hernia repairs from January 1996 to December 1997 at a 228-bed hospital. Prolene mesh was stapled to the peritoneal surface of the abdominal wall, leaving sac in situ and mesh uncovered. Patients were seen by the operating surgeon within 2 months, and by an impartial surgeon (J.S.) after 3 to 14 months (average, 7 months; median, 6 months). Results: Repairs involved 44 hernias with orifice sizes 2 to 20 cm in diameter, and an average area of 20 cm². Of these 44 hernias, 36 were postoperative and 8 primary. Furthermore, 20% were recurrent hernias. There were four conversions. The outpatient rate was 98%, with one readmission for ileus. The early recurrence rate was 5%. Conclusions: Laparoscopic mesh onlay repair is a safe, easy, and effective procedure with minimal discomfort and a low early recurrence rate that can be performed safely on an outpatient basis.

Critical evaluation of a novel DualMesh repair for large hiatal hernias

Background  The use of mesh for laparoscopic repair of large hiatal hernias may reduce recurrence rates in comparison to primary suture repair. However, there is a potential risk of mesh-related oesophageal complications due to prosthesis erosion. The aim of this study was to critically evaluate a novel mesh (DualMesh) repair of hiatal hernias with particular reference to intraluminal erosion. Method  Medical records of 19 patients who underwent laparoscopic hiatal hernia repair with DualMesh reinforcement of the crural closure were reviewed from a prospectively collected database. Quality of life and symptom analysis was performed using quality of life in reflux and dyspepsia (QOLRAD) questionnaires pre- and postoperatively after 6 weeks, 6 months, 1 year and 2 years. Barium studies were performed on patients pre-operatively and two years postoperatively to assess hernia recurrence. After 2 years, oesophagogastric endoscopy was performed to assess signs of erosion. Results  Mean patient age was 70.5 years (range 49–85 years). Two years after hiatal hernia repair, there was significant improvement in quality-of-life scores (QOLRAD: p < 0.001). Follow-up barium studies performed at 31.3 months (range 29–40 months) after surgery showed moderate recurrent hernias (>4 cm) in 1/14 patients (7%). Endoscopies performed at 34.4 months (range 28–41 months) after surgery did not show any signs of prosthetic erosion. Conclusion  Laparoscopic reinforcement of primary hiatal closure with DualMesh leads to a durable repair in patients with large hiatal hernias. Long-term endoscopic follow-up did not show any signs of mesh erosion after prosthetic reinforcement of the crural repair.     

Laparoscopic extraperitoneal inguinal hernia repair in the day-care setting

Background: Totally extraperitoneal (TEP) laparoscopic inguinal hernia repair is gaining popularity, and our preference is to perform this procedure as a day case. This study evaluates the suitability of TEP repair in the day-care setting. Methods: A policy of day-care TEP repair, unless contraindicated, was adopted for inguinal hernia repair, and the outcome was prospectively evaluated. Of 87 consecutive inguinal hernia repairs, day-care TEP was possible in 54 (62%); 17 (20%) were in-patient TEP, 14 (16%) were open repairs, and 2 (2%) were converted from TEP to open repairs. Results: Among day-care TEP repairs, median visual analog pain score at discharge was 2.3/10, and 43% of patients had no pain. Complications included cord hematoma 2 (4%) and seroma 3 (6%). Median times for stopping analgesia, resumption of full activity, and return to work were 3, 3, and 6 days respectively. Complete satisfaction with day-care TEP was expressed by 91% of patients; 9% were moderately satisfied, and none expressed dissatisfaction. Conclusions: Day-care TEP repair is feasible in the majority of patients with inguinal hernias, and it is associated with minimal complications, excellent recovery, and a high degree of patient satisfaction.

Laparoscopic intraperitoneal polytetrafluoroethylene (PTFE) prosthetic patch repair of ventral hernia

Background: The purpose of this study was to determine whether laparoscopic intraperitoneal polytetrafluoroethylene (PTFE) prosthetic patch (LIPP) repair of a ventral hernia is superior to open prefascial polypropylene mesh (OPPM) repair in a tertiary care university hospital in an urban environment. Methods: Data on 39 consecutive patients undergoing either LIPP repair (n= 21) or OPPM repair (n= 18) were compared. Results: Findings showed that LIPP repair is characterized by less painful recovery and shorter hospital stay, with 90% of patients treated successfully as outpatients as compared with 7% in the OPPM group. The total facility costs for the LIPP repair ($8,273 ± $2,950) was significantly lower than for the OPPM repair ($12,461 ± $5,987) (p < 0.05). Two serious delayed complications in the LIPP group were treated by reoperation (colocutaneous fistula, mesh infection), but the higher readmission costs in this group did not negate the overall cost advantage for LIPP repair. In the follow-up evaluation, 1 hernia recurrence was found in the LIPP repair group, and none in the OPPM group. Conclusions: Initial experience suggests that LIPP repair has advantages over OPPM repair in terms of decreased hospitalization, postoperative pain, and disability. Refinements in the technique to reduce complications may make LIPP repair the procedure of choice for repair of ventral hernias. Received: 5 June 1998/Accepted: 15 October 1999     

Do recurrences after paraesophageal hernia repair matter?

Background The recurrence rate for paraesophageal hernias (PEH) can be as high as 30% following laparoscopic repair. The aim of this study was to determine the severity of symptoms in patients with recurrences and the need for reoperation 10 years after surgery. Methods and Procedures Consecutive laparoscopic paraesophageal cases performed at a single institution between 1993 and 1996 were identified from the institution’s foregut database. Patients were asked about the presence and severity of symptoms (heartburn, chest pain, regurgitation, and dysphagia). Patients were also asked whether they had (1) been diagnosed with hernia recurrence or (2) undergone repeat surgical intervention. Results Complete follow-up was obtainable in 31 of the total of 52 patients (60%). The proportion of patients reporting moderate/severe symptoms was less at 10 years than preoperatively: heartburn 12% versus 54% (p < 0.001), chest pain 9% versus 36% (p = 0.01), regurgitation 6% versus 50% (p < 0.001), and dysphagia 3% versus 30% (p = 0.001). Two patients underwent repeat surgical intervention for symptomatic recurrences within the first postoperative year. Eight more patients have been diagnosed with hernia recurrences on either contrast esophagram or upper endoscopy but had not required reoperation. At ten years, more patients with hernia recurrence had heartburn than those who did not have recurrences (60% versus 14%; p < 0.05). Conclusions Despite a hiatal hernia recurrence rate of 32% 10 years after surgery, laparoscopic PEH was a successful procedure in the majority of patients; most remained symptomatically improved and required no further intervention 10 years after surgery.
