Laparoscopic repair of postoperative perineal hernia

Background Perineal hernia is an uncommon complication following abdominoperineal resection of the rectum. There are only a few reports concerning the management of this unusual problem. Various methods of repair have been described, but none of them is well established. The purpose of our study is to present our experience and to discuss the pathogenesis and the different surgical repair techniques of these hernias. Methods Between September 2003 and December 2004, four patients with perineal hernia observed several months following laparoscopic abdominoperineal resection for adenocarcinoma of the lower rectum were treated. All patients underwent the transabdominal laparoscopic approach using synthetic mesh for repair. Results In all patients, the hernia was repaired by the laparoscopic transabdominal approach using synthetic mesh. The blood loss was minimal and mean operating time was 54 ± 10 min. There were no cases that required conversion to laparotomy and there were no intraoperative or postoperative complications. Beginning of soft diet intake and ambulation times were on the second day following surgery. The average length of hospital stay was 4 ± 1 days. During 8.3 ± 6 months of follow-up, there was no recurrence of the hernia. Conclusion Perineal hernias are rare complications of major pelvic surgeries. Symptomatic hernias should be repaired surgically. The transabdominal laparoscopic approach using synthetic mesh provides an appropriate solution for these hernias.

Primary perineal hernia: a case report and review of the literature

Abstract Pelvic floor hernias are extremely rare. This study presents a successfully treated case of primary perineal hernia and takes a look at the existing literature. Case The case of a 75-year-old female patient with a great perineal hernia is presented. Diagnosis was secured by magnetic resonance tomography. The pelvic defect was successfully treated by primary suture with Prolene. Discussion The literature shows many different approaches for treatment of perineal hernia, such as open or laparoscopic mesh repair, and perineal, abdominal or combined access. Our case confirms that primary closure of the hernial orifice through an abdominal approach is also feasible.     

Obturator hernia repair – a new technique

Obturator hernia is a rare condition with few reports in the world literature. There appears to be no consensus on the ideal approach and repair for such a condition. We report a simple, quick technique via a lower midline incision using an autogenous peritoneal fold. It is ideal for the contaminated case and in settings where mesh is not readily available.

Use of histoacryl® for incisional hernia repair

Summary The use of fibrin glues for the closure of wounds in mesh repair of abdominal wall incisional hernias has been found to reduce the morbidity rate. However, the substances of this type derived from blood have the potential risk of virus transmission. The application of a nonbiologic adhesive would eliminate this risk, while offering the same advantages. We have performed a prospective study with the aim of analyzing results of the application of enbucrylate (Histoacryl ?, B. Braun Melsungen AG, Germany) between the muscle layers and subcutaneous tissue after incisional hernia repair with associated dermolipectomy, assessing local morbidity, mean hospital stay and need of wound care. The study included 42 patients divided into two groups, with and without enbucrylate, and results were compared between the groups. The two groups of patients were homogeneous with respect to their clinical data. The incisional hernia was at the midline in all cases, and was repaired using retromuscular prefascial polypropylene mesh in combination with dermolipectomy. Patients in the Histoacryl ? group developed less local morbidity (seromas, hematomas or abscesses) (p < 0.05), had a shorter mean hospital stay (p < o.o1) and required less wound care. We found that this approach improved the results of surgery for large eventrations when repaired by mesh placement and dermolipectomy and decreased global cost because morbidity and hospital stay were reduced.     

Incisional hernia repair in Sweden 2002

Incisional hernia is a common problem after abdominal surgery. The complication and recurrence rates following the different repair techniques are a matter of great concern. Our aim was to study the results of incisional hernia repair in Sweden. A questionnaire was sent to all surgical departments in Sweden requesting data concerning incisional hernia repair performed during the year 2002. Eight hundred and sixty-nine incisional hernia repairs were reported from 40 hospitals. Specialist surgeons performed the repair in 782 (83.8%) patients. The incisional hernia was a recurrence in 148 (17.0%) patients. Thirty-three per cent of the hernias were subsequent to transverse, subcostal or muscle-splitting incisions or laparoscopic procedures. Suture repair was performed in 349 (40.2%) hernias. Onlay mesh repair was more common than a sublay technique. The rate of wound infection was 9.6% after suture repair and 8.1% after mesh repair. The recurrence rate was 29.1% with suture repair, 19.3% with onlay mesh repair, and 7.3% with sublay mesh repair. This survey revealed that there is room for improvement regarding the incisional hernia surgery in Sweden. Suture repair, with its unacceptable results, is common and mesh techniques employed may not be optimal. This study has led to the instigation of a national incisional hernia register.     

Mini-mesh repair for femoral hernia

INTRODUCTION

Femoral hernia consists only 4% of all primary groin hernias. It is described as “the Bête Noire of Hernias” because of its nature and anatomy which is difficult to understand for the surgeons and tendency to recurrence. Although there is some large series of femoral hernia in the literature, few studies prospectively comparing repair techniques especially for this type of hernia has been published. A new technique named mini-mesh repair is described here.

PRESENTATION OF CASE

After hernia sac is dissected completely and sent back into the preperitoneal space, femoral canal is exposed. A round or oval shaped patch is prepared in 1.5–2.5 cm in diameter according to the size of the femoral canal. Mesh is secured to the Cooper''s ligament with 2/0 polypropylene suture. Eight femoral hernias in 8 patients were repaired with this new technique. Patient satisfaction is very good. One seroma and one limited ecchymosis were recorded. No recurrence was observed in a mean follow-up of 22.4 months. No chronic pain was recorded.

DISCUSSION

Many techniques for femoral hernia repair have been described to date with a variety of clinical outcomes. Each technique has its own advantages and disadvantages. Mesh repairs without tension seems to be better choices. When the transversalis fascia is healthy and strong in a patient with femoral hernia a large piece of mesh may be unnecessary. The simple technique described in this paper can be a good alternative. It is totally problem-oriented, and the burden of prosthetic material is very limited.

CONCLUSION

Mini mesh repair may be a good solution for selected patients with femoral hernia.

Traumatic abdominal wall hernia: Delayed repair: Advantageous or taxing

INTRODUCTIONTraumatic abdominal wall hernia (TAWH) is a rare entity. Most cases occur in children, following an injury from the bicycle handle bar. In adults, it usually results from road traffic accidents (RTA). We present one of the largest reported cases of TAWH following RTA managed by delayed mesh repair.PRESENTATION OF CASEA 35 yr old obese male with RTA was diagnosed with TAWH with 19 cm × 15 cm defect in left flank. As there were no intra abdominal injuries and overlying skin was abraded, he was planned for elective repair after 6 months. On exploration a defect of 30 cm × 45 cm was found extending from midline anteriorly to 8 cm short of midline posteriorly in transverse axis and costal margin to iliac crest in craniocaudal axis. After restoration of bowel into abdominal cavity, primary closure or even approximation of muscular defect was not possible thus a mesh closure using 60 cm × 60 cm prolene mesh in subcutaneous plane was done. After 4 months follow up, patient is healthy and has no recurrence.DISCUSSIONEmergent surgical management of TAWH is usually favoured due to high incidence of associated intra abdominal injuries. Delayed repair may be undertaken in selected cases.CONCLUSIONTAWH, although rare, should be suspected in cases of RTA with abdominal wall swellings. With time, the hernia defect may enlarge and muscles may undergo atrophy making delayed repair difficult.

Polyester composite versus PTFE in laparoscopic ventral hernia repair

Introduction:

Both polyester composite (POC) and polytetrafluoroethylene (PTFE) mesh are commonly used for laparoscopic ventral hernia repair. However, sparse information exists comparing perioperative and long-term outcome by mesh repair.

Methods:

A prospective database was utilized to identify 116 consecutive patients who underwent laparoscopic ventral hernia repair at The Mount Sinai Hospital from 2004-2009. Patients were grouped by type of mesh used, PTFE versus POC, and retrospectively compared. Follow-up at a mean of 12 months was achieved by telephone interview and office visit.

Results:

Of the 116 patients, 66 underwent ventral hernia repair with PTFE and 50 with POC mesh. Patients were well matched by patient demographics. No difference in mean body mass index (BMI) was demonstrated between the PTFE and POC group (31.8 vs. 32.5, respectively; P=NS). Operative time was significantly longer in the PTFE group (136 vs.106 minutes, P<.002). Two perioperative wound infections occurred in the PTFE group and none in the POC group (P=NS). No other major complications occurred in the immediate postoperative period (30 days). At a mean follow-up of 12 months, no significant difference was demonstrated between the PTFE and POC groups in hernia recurrence (3% vs. 2%), wound complications (1% vs. 0%), mesh infection, requiring removal (3% vs. 0%), bowel obstruction (3% vs. 2%), or persistent pain or discomfort (28% vs. 32%), respectively (P=NS).

Conclusion:

Our study demonstrated no significant association between types of mesh used and postoperative complications. In the 12-month follow-up, no differences were noted in hernia recurrence.     

Laparoscopic ventral hernia repair under spinal anesthesia: a feasibility study

BACKGROUND: Regional anesthesia has not been used as the sole anesthetic procedure in laparoscopic ventral hernia repair due to the fear of potential adverse effects of the pneumoperitoneum. However, there are recent reports on the feasibility of performing laparoscopic procedures, such as cholecystectomy, in fit patients, under spinal anesthesia alone. The current study aimed to detect the feasibility of performing laparoscopic ventral hernia repair under spinal anesthesia. METHODS: Twenty-five American Society of Anesthesiologists (ASA) I or II patients underwent laparoscopic ventral hernia repair with low-pressure CO2 pneumoperitoneum under spinal anesthesia. In 9 cases the hernia was umbilical/para-umbilical, in 5 cases epigastric, and in 11 cases incisional. Intraoperative incidents, complications, postoperative pain, and recovery in general, as well as patient satisfaction at follow-up examination, were prospectively recorded. RESULTS: All operations were completed laparoscopically and conversion from spinal to general anesthesia was not required in any of the cases. Median pain score at 4 hours postoperatively was .5 (range 0-5), at 8 hours 1.5 (range 0-6), and at 24 hours 1.5 (range 0-4). Most patients were discharged 24 hours after the operation; the median hospital stay was 1 day (range 1-3 days). At 2-weeks follow-up, no late complications were detected and all patients reported being satisfied with the anesthetic procedure. CONCLUSION: Laparoscopic ventral hernia repair with low-pressure CO2 pneumoperitoneum can be successfully and safely performed under spinal anesthesia. Furthermore, it seems that spinal anesthesia is associated with minimal postoperative pain and smooth recovery.     

Lichtenstein repair of inguinal hernia with Surgisis inguinal hernia matrix soft-tissue graft in immunodepressed patients

While polypropylene mesh remains the preferred prosthesis material for hernioplasties, there are some problems with infections, intestinal obstruction and fistulization, and migration particularly in immunodepressed patients. A new degradable and reabsorbable material, the porcine small intestinal submucosa (Surgisis) has been developed for hernia repairs in humans. This prospective study evaluated the safety and efficacy of Lichtenstein hernioplasty using the Surgisis inguinal hernia matrix soft-tissue graft as a mesh in ten immunodepressed subjects. Six subjects were HIV-positive in the immunodepressive phase, and the other four had undergone transplantation (three kidney, one liver). There were no intraoperative or postoperative complications, recurrences, or wound infections. Thus Lichtensteins hernioplasty using the Surgisis inguinal hernia matrix soft-tissue graft in immunodepressed patients promises safety and efficacy.     

Postoperative pain after laparoscopic ventral hernia repair: a prospective comparison of sutures versus tacks.

BACKGROUND AND OBJECTIVES: Mesh fixation in laparoscopic ventral hernia repair typically involves the use of tacks, transabdominal permanent sutures, or both of these. We compared postoperative pain after repair with either of these 2 methods. METHODS: Patients undergoing laparoscopic ventral hernia repair at the Mount Sinai Medical Center were prospectively enrolled in the study. They were sorted into 2 groups (1) those undergoing hernia repairs consisting primarily of transabdominal suture fixation and (2) those undergoing hernia repairs consisting primarily of tack fixation. The patients were not randomized. The technique of surgical repair was based on surgeon preference. A telephone survey was used to follow-up at 1 week, 1 month, and 2 months postoperatively. RESULTS: From 2004 through 2005, 50 patients were enrolled in the study. Twenty-nine had hernia repair primarily with transabdominal sutures, and 21 had repair primarily with tacks. Both groups had similar average age, BMI, hernia defect size, operative time, and postoperative length of stay. Pain scores at 1 week, 1 month, and 2 months were similar. Both groups also had similar times to return to work and need for narcotic pain medication. CONCLUSIONS: Patients undergoing laparoscopic ventral hernia repair with primarily transabdominal sutures or tacks experience similar postoperative pain. The choice of either of these fixation methods during surgery should not be based on risk of postoperative pain.     

Evaluation of DualMesh for repair of large hiatus hernia in a porcine model

BACKGROUND: Prosthetic fascial grafts are frequently used for augmentation of cruroplasty in large hiatus hernia repair to decrease the chances of recurrence. Potential complications such as intraluminal erosion may be related to the constant movement of mesh and diaphragm over the outer surface of the esophagus. This study aimed to evaluate DualMesh for repair of large hiatal defects in a porcine model. METHODS: In this study, 18 Landrace x large white x Duroc crossbred pigs underwent either primary hiatal repair or tension-free prosthetic repair using DualMesh (80 x 50 mm or 80 x 100 mm). The animals were killed at 3 or 28 weeks for macroscopic and histologic evaluation of the hiatal region and gastroesophageal junction. RESULTS: All grafts had become encapsulated at 28 weeks, and the majority had filmy adhesions only to the visceral aspect. In all models, the esophagus moved freely over the cut edge of the prosthesis. No signs of intraluminal erosion were documented. At histologic examination, significant ingrowth was noted on the porous side of the mesh, whereas no defined mesothelial layer was identified on the capsule of the nonporous side. CONCLUSION: In this animal model of large hiatus hernia repair, DualMesh showed optimal characteristics in terms of host tissue incorporation on the porous side and absence of adhesions on the visceral side of the prosthesis. The absence of adhesions and intraluminal erosion in this study may provide reassurance to surgeons using mesh at the hiatus.     

The open tension-free mesh repair of inguinal hernia Analysis of 1,235 cases

Summary 1235 outpatient repairs of inguinal hernias under local anesthesia with IV sedation were performed between September 1993 and June 1997. The average age was 63. Twelve percent were recurrent repairs. All indirect hernias and all focal diverticular type V direct defects were treated with a cone-shaped polypropylene plug plus an overlay mesh strip. All broad fusiform type IV direct defects were repaired either by the same plug method or in the manner of a Lichtenstein repair. Mortality was zero. There were 3 recurrences, 5 superficial hematomas, 5 seromas, 1 questionable neuralgia, 1 dysejaculation, 1 ischemie orchitis, 1 flare-up of gout and 1 TIA, for a complication rate of 1.46%. Infection rate was zero. Recurrence rate thus far is only 0.24%, 0.16% for primary repair and 0.67% for recurrent repair.

Robot-assisted laparoscopic repair of perineal hernia after abdominoperineal resection: A case report and review of the literature

IntroductionPerineal hernia is a protrusion of the pelvic floor containing intra-abdominal viscera. The occurrence of postoperative perineal hernia after abdominoperineal resection (APR) is rare, but reports have indicated a recent increase in occurrence following surgical treatment for rectal cancer. This has been attributed to a shift towards extralevator abdominoperineal resection, together with more frequent and long-term use of neoadjuvant therapy.Presentation of caseHere, we report the case of a patient who underwent APR for cancer. Twenty months postoperative, a perineal hernia was detected. The patient was electively scheduled for surgery. Robot-assisted laparoscopy was performed using the da Vinci Surgical System. The perineal hernia was repaired by primary closure with the placement of Symbotex Composite mesh as reinforcement for the pelvic floor. The surgery was performed without any adverse events, and the patient was discharged the day after surgery. Clinical follow-up proceeded at the designated time intervals without difficulties.DiscussionRecurrence rates of perineal hernia remain high, and surgeons face numerous challenges related to poor view, suturing and mesh placement in the deep pelvis. Numerous approaches have been described, but there is still no consensus as to the optimal repair technique for perineal hernia.ConclusionSymptomatic perineal hernias can feasibly be repaired with robot-assisted laparoscopy. Furthermore, suturing and mesh placement require less effort with the robot approach when compared to the open and laparoscopic approaches. These promising findings are demonstrated in the included video.
