[Laparoscopic hernia repair. A useful method for surgical treatment of inguinal hernia?].

Between September 1992 and May 1993 14 groin hernias in 13 patients were treated with laparoscopic transabdominal preperitoneal repair using a polypropylene mesh to reinforce the abdominal wall. There were two indirect and 12 direct hernias. Five hernias were recurrent. There were no perioperative complications. In the follow up period 14-24 months after the operations, two patients developed recurrent hernias after four and ten months respectively, one patient presented with a new hernia on the contralateral side, and one patient died from cardiac disease. Laparoscopic hernia repair is technically demanding and in our setting is more time- and resource consuming than an open, tension-free repair. Thus it is questionable whether this method should be used in primary hernia repair. It may, however, have a place in the treatment of recurrent hernias and bilateral hernias.

[Function of the abdominal wall and development and therapy of hernias (among others: the para-colostomy hernia)].

The peritoneal cavity has a fascial skeleton with musculature that is nearly always active, i.e. it has resting tone activity. During pneumoperitoneum this resting activity increases very markedly. The pelvic floor and its integrated sphincters also have a similar type of spontaneous activity depending on Onuf's nucleus in the spinal cord together with the somatic and autonomic nerves. Hernias such as umbilical hernias develop with disruption of a scar. While in a child the common inguinal hernia develops in an open vaginal processus, in an adult it develops as the result of a congenital muscular defect in the abdominal wall. A femoral hernia develops in a gap through the pressure of the resting activity of the abdominal wall. A paracolostomy hernia develops after an incision in the fascial skeleton and after pull-through of a very adipose sigma-mesosigma. It can often be treated it by pulling a slim colon segment through the innervated rectus muscle incision and closing the gap in the fascial skeleton with a running suture. Incisional or umbilical hernias can be successfully treated by suturing with a continuous nonabsorbable thread. The best therapy for inguinal hernias is suturing of the hyperplastic fascia transversalis and the reconstruction of the muscle sphincter mechanism. Bassini operated on very large hernias with hyperplastic fascia, thereby achieving excellent results. Fascial hyperplasia has been shown to follow the use of tissue expanders.

A rare cause of intestinal obstruction: incarcerated femoral hernia, strangulated obturator hernia.

Obturator hernia may occur bilaterally in association with another hernia, which is usually of the femoral type. We present a 77-year-old-woman who had abdominal pain with nausea and vomiting together with swelling of the right groin for 3 days. Incarcerated right femoral hernia and consequent mechanical small-bowel obstruction was diagnosed, and urgent operation was undertaken. As the incarcerated femoral hernia reduced spontaneously during the induction of anesthesia, a lower median incision was performed. During exploration, the real cause of mechanical intestinal obstruction was found to be a small intestinal loop strangulated in the left obturator hernia. Right femoral and left obturator hernia were repaired with preperitoneal polypropylene mesh. If there is enough time and general condition of the older patient is suitable, further diagnostic techniques for concomitant obturator hernias may be useful in patients who present with signs of incarcerated inguinal hernia and intestinal obstruction.

Laparoscopic versus open repair of groin hernia: a randomised comparison. The MRC Laparoscopic Groin Hernia Trial Group.

BACKGROUND: Repair of a groin hernia is one of the most common elective operations performed in general surgery. Our aim was to compare laparoscopic repair with open repair of groin hernia. METHODS: 928 patients with groin hernia, from 26 hospitals in the UK and Ireland, were randomly assigned to laparoscopic repair (n=468) or to open hernia repair (n=460, of which 433 were tension-free mesh repairs). Patients were clinically assessed at 1 week and 1 year after surgery, and were sent questionnaires at 3 months and 1 year. The primary endpoints were: complications; return to usual activities of social life (as the most generally applicable example of return to usual activities); hernia recurrence; groin pain that persisted at 1 year; and costs to the health services. All analyses were by intention to treat. FINDINGS: At 1 week, at least one complication was found in 108 (29.9%) patients allocated to laparoscopic repair and in 155 (43.5%) patients allocated to open repair (95% CI for difference -20.6% to -6.6%, p<0.001). There were three serious surgical complications all of which occurred in the laparoscopic group. Patients in the laparoscopic group returned to the usual activities of social life sooner than the patients in the open repair group (10 [IQR 7-21] vs 14 [7-28] days, p=0.004). At 1 year after the operation, the laparoscopic group had a lower rate of persistent groin pain than those who had open repair (28.7% vs 36.7% [95% CI for difference -14.7% to -1.4%], p=0.018). However, all seven hernia recurrences occurred in the laparoscopic group and not in the open repair group (1.9% vs 0.0% [95% CI for difference 0.5% to 3.4%], p=0.017). INTERPRETATION: Although laparoscopic hernia repair has advantages for patients, concerns about safety indicate that open repair is the more appropriate option for the general surgeon. Our findings lend support to the move towards laparoscopic hernia surgery becoming part of the domain of specialist surgeons.

[Giant Spigelian hernia associated with inguinal hernia. Repair with polypropylene prosthesis].

Spigelian or lateral ventral hernia is a rare pathology, representing about 2% of all abdominal wall hernias. This kind of hernia can be found in the area limited from the umbilicus and anterosuperior iliac spine, near the lateral edge of the rectus abdominis. The authors describe a rare case of "giant" Spigelian hernia related with homolateral direct inguinal hernia. A seventy-year-old and obese patient had a painless huge intumescence in the right side of periumbilical area, and besides--he had a homolateral direct inguinal hernia. Abdominal computerized tomography visualized a hernial gap, which diameter is larger than 7 cm, in pararectal subumbilical site and a wide herniated bowel in interaponeurotic site. This double hernial pathology has been treated in an only solution, placing an only subfascial polypropylene prosthesis, overlapping both hernial defects. The authors believe prosthetic "tension free" repair, previous suture of the defect, represents a gold standard in the treatment of Spigelian hernia. Such refined technique allows an effective repair especially when aponeurotic defect is out of size and/or is related with subsequent homolateral hernia, also allowing an early patient's rehabilitation.

Preoperative computed tomography finding predicts for postoperative inguinal hernia: new perspective for radical prostatectomy-related inguinal hernia.

OBJECTIVES: To investigate the incidence of radical prostatectomy-related inguinal hernia (RPRIH) and the predictive factors for RPRIH. METHODS: We reviewed the medical charts of patients who had undergone retropubic radical prostatectomy (RRP) at our institution from January 2002 to December 2004 and had a median follow-up of 17 months (range 3 to 42). All patients were examined for RPRIH every 3 months. We also reviewed the computed tomography results in a blinded manner and investigated the predictive factors for RPRIH with multivariate analysis using the Cox proportional hazards model. RESULTS: Of 98 patients analyzed, 17 were diagnosed with RPRIH after RRP (17.3%) at the median of 7 months (range 3 to 12). Preoperative computed tomography results were available for all patients, and subclinical inguinal hernia was identified in 20 (20.4%) of the 98 patients. Multivariate analysis showed that a subclinical inguinal hernia was the single predictive factor for RPRIH. The estimated rate of RPRIH was 60.6% in the subclinical inguinal hernia group and 9.5% in the normal group at 12 months (log-rank test, P <0.001). CONCLUSIONS: The results of the present study have indicated that a preoperative computed tomography finding of a subclinical inguinal hernia predicts for postoperative inguinal hernia formation after RRP. RRP might only advance the time at which the inguinal hernia would develop with or without surgery. Thus, all patients with a subclinical inguinal hernia finding should be informed about the possibility of the development of RPRIH within 12 months after RRP and recommended to undergo surgical repair at RRP.

Inguinal hernia revisited through comparative evaluation of peritoneum, processus vaginalis, and sacs obtained from children with hernia, hydrocele, and undescended testis.

BACKGROUND/PURPOSE: Histological structures of peritoneum, processus vaginalis, and sacs obtained from girls with inguinal hernia and boys with inguinal hernia, hydrocele, and undescended testis have been compared through immunohistochemical features to evaluate if any clue descriptive for the etiology of inguinal hernia exists. METHODS: Parietal peritoneums (n = 6), processus vaginalises (n = 4), female hernia sacs (n = 5), male hernia sacs (n 12), and sacs from hydrocele (n = 5) and undescended testis (n = 9) were stained with indirect immunoperoxidase method. Anti-CD9, CD26, CD29, CD31, CD36, CD44, CD49a, CD49b, CD49c, CD49d, CD49e, CD49f, CD54, CD55, CD56, CD62E & P, CD71, CD98, CD102, CD106, CD146, CD151 monoclonals and NFL-NPH, S-100 antiserums were used. The histological structures of each group of samples were identified and compared. RESULTS: Smooth muscle layers have been encountered within the walls of hernia sacs of both boys and girls. Although the hydrocele sacs have shown smooth muscle bundles distributed as patchy areas, smooth muscle bundles have been observed infrequently among sacs from patients with undescended testis. Peritoneum and processus vaginalis samples have been free of smooth muscle. CONCLUSIONS: Inguinal hernia during childhood seems to be related to the presence of smooth muscle within the wall of the sac. The smooth muscle bundles may have played a role both in prevention of obliteration and clinical outcome. Because the sacs associated with undescended testis are without smooth muscles, and herniation is not a frequent association, they may not share the same etiologic basis with inguinal hernia.

Pseudomyxoma peritonei in a hernia sac: analysis of 20 patients in whom mucoid fluid was found during a hernia repair.

INTRODUCTION: Pseudomyxoma peritonei syndrome is a rare disease that causes extensive accumulation of non-invasive mucinous tumour and mucinous fluid throughout the abdomen and pelvis. The primary tumour is a perforated appendiceal adenoma or mucinous adenocarcinoma. In patients with an open processus vaginalis or other peritoneal defect, the adenomatous epithelial cells may accumulate within the hernia sac, causing mucoid fluid to be present at the time of hernia repair. MATERIALS AND METHODS: From February 1991 to September 1997, the diagnosis of pseudomyxoma peritonei syndrome was established in 20 patients in whom mucoid material was found in a hernia sac during a hernia repair. Clinical features of these patients were critically evaluated using the completeness of cytoreduction as an endpoint. RESULTS: The treatments delivered at the time of hernia repair had no impact on the outcome. A lack of interim events vs the use of interim treatments between hernia repair and definitive cytoreduction was significant in relation to a complete vs incomplete cytoreduction. Non-aggressive histology and an interval of less than 1 year was statistically significantly associated with a favourable outcome from surgical intervention. CONCLUSION: When mucoid fluid is encountered at the time of a hernia repair, recovery of that fluid and the hernia sac for histologic study is important. When adenomatous epithelial cells are present, a CT scan should be performed to look for the typical distribution of mucinous tumour and fluid that suggests the pseudomyxoma peritonei syndrome. If the diagnosis can be confirmed, referral to a centre experienced in the treatment of this rare disease is suggested.

Radiologist performance in the diagnosis of internal hernia by using specific CT findings with emphasis on transmesenteric hernia.

PURPOSE: To evaluate the performance of radiologists in the diagnosis of internal hernia with specific computed tomographic (CT) findings. MATERIALS AND METHODS: Abdominal CT scans obtained in 42 patients were retrospectively reviewed by three radiologists. The case group consisted of 18 patients with internal hernias (two paraduodenal, 16 transmesenteric); the comparison group was 24 patients with no internal hernia. Images were reviewed in a random and blinded fashion. Individual and group performance was evaluated with receiver operating characteristic (ROC) analysis, and interobserver agreement was measured with Cronbach coefficient alpha. Individual CT signs relevant as predictors of transmesenteric hernia were identified with logistic regression analysis and ranked by their odds ratio and P values. RESULTS: Both paraduodenal hernias were diagnosed by all readers on the basis of CT signs, including a retrogastric saclike mass of small-bowel loops. Diagnosis of transmesenteric hernia was more difficult and variable, with an average accuracy of area under the ROC curve (A(z)) of 77%, sensitivity of 63%, and specificity of 76%. CT signs of transmesenteric hernia were recognized consistently (Cronbach coefficient alpha >or= 0.80) and included a cluster of dilated small-bowel segments and stretching and displacement of mesenteric vessels. Coexisting volvulus and ischemia were diagnosed with low sensitivity (46% and 43%, respectively) but high specificity (96% and 98%, respectively). CONCLUSION: Diagnosis of internal hernia with CT remains difficult. Special attention should be given to the clustering of bowel loops, the mesenteric vessels, and signs of small-bowel obstruction.

Laparoscopic groin hernia surgery: the TAPP procedure. Transabdominal preperitoneal hernia repair.

OBJECTIVE: To describe the technique and results of laparoscopic transabdominal preperitoneal (TAPP) hernia repair. DESIGN: A case series, with a detailed description of the operative technique. SETTING: A university affiliated hospital. PATIENTS: A consecutive series of 554 patients (494 male, 60 female) who underwent laparoscopic hernia repair in a single institution. The mean follow-up was 14 months. INTERVENTIONS: Laparoscopic TAPP hernia repair was performed in almost all patients. Simple closure was performed in a patient with a strangulated hernia, and a mesh-based repair was used in a patient with bilateral obturator hernias. MAIN OUTCOME MEASURES: Complications and recurrence. RESULTS: The laparoscopic TAPP repair was successful in 550 of the 554 patients who underwent 632 hernia repairs. conversion was necessary in 4 patients. Complications were infrequent and there were no recurrences. Only 3.4% of patients were lost to follow-up. The most frequent complications were urinary retention (27) and hematoma and seroma (38) in the early postoperative period. Neuralgia (11) and hydrocele (10) also occurred. Mesh infection occurred in only 1 patient and port-site hernias in 3 patients. there was 1 death from an acute myocardial infarction. CONCLUSION: Laparoscopic TAPP hernia repair is associated with an exceedingly low recurrence rate and an acceptable complication rate.

Laparoscopic repair of Morgagni hernia and paraesophageal hernia on the same patient.

Morgagni hernias have been recognized with increasing frequency as a source of abdominal pain and dyspnea in adults. Morgagni hernias are rarely accompanied by paraesophageal hernias. We report a case of Morgagni hernia associated with paraosephageal hernia, both repaired laparoscopically. On the 65-year-old woman patient, diaphragmatic defect and paraesophageal hernia were closed with primary sutures, and Hill-type gastropexy was performed successfully. The procedure lasted 115 min. The patient was discharged 5 days after surgical treatment and there were no complications following the operation. Primary closure with direct sutures is rapid, simple, and effective and can be combined with other laparoscopic procedures, as in our case. It can be performed by surgeons trained in intracorporeal suturing and knotting in all kinds of hospitals. The laparoscopic approach to Morgagni hernias minimizes trauma and shortens postoperative hospital stay, and patients have a comfortable postoperative period.

Combination of paraesophageal hernia and Morgagni hernia in an old patient.

Paraesophageal hiatal hernia is an uncommon condition that requires urgent correction to prevent life-threatening complications. It is present in 14% of all hiatal hernias. The incidence of Morgagni hernia among all diaphragmatic defects is 3-4% and about 90% of the hernias occur on the right, 8% are bilateral and 2% are on the left. The combination of a Morgagni hernia and paraesophageal hernia is very rare and only four cases have been reported in the literature. All of them occurred in the right. This report describes an old case admitted to our clinic with dyspnea, chest pain and chronic gastrointestinal symptoms, found to have combined left Morgagni and paraesophageal hernia. Surgical repair was performed via transabdominal approach. This unusual case and surgical approaches are discussed in light of the data presented in the literature.

[Risks and benefits of laparoscopic hernia-plasty (TAPP). 5 years experiences with 3,400 hernia repairs].

In the present study, for the first time the aspects of risk, benefit and the costs of laparoscopic hernioplasty in the transabdominal technique with preperitoneal placement of a polypropylene mesh are examined prospectively in a very large group of patients with 3,400 hernia repairs. The median operation time was 45 min for unilateral primary hernias, 50 min for unilateral recurrent hernias and 76 min for bilateral hernias. The frequency of complications showed a significant dependence on the individual steps in the development of the method and the individual learning curve. The same is true for the rate of recurrency. Whereas initially the rate of serious complications was 2.75%, the rate of minor complications 11% and the rate of recurrences 4.5% the corresponding figures are at present 0.4%, 4.4% and 0.5%. Laparoscopic hernioplasty proved to be equally as effective in the treatment of primary hernias, recurrent hernias and bilateral hernias. The large number of 11 surgeons participating proves that laparoscopic hernioplasty can be learned and that even in a teaching hospital it can be performed safely, efficiently and cost-effectively.

Laparoscopic transperitoneal hernia repair of incarcerated hernias: Is it feasible? Results of a prospective study.

BACKGROUND: Laparoscopic transperitoneal hernia repair (TAPP) has proved its efficiency in elective surgery. However, TAPP results with incarcerated hernias still are unknown. METHODS: Data from a prospective study were evaluated with regard to TAPP repair for both chronically and acutely incarcerated hernias. RESULTS: During a 6-year period, 220 incarcerated hernias were repaired (194 via TAPP). The median operation time for TAPP was 55 min. An accompanying resection therapy became necessary for only four of the emergency cases (11.1%) and two of the chronically incarcerated cases (1.3%) in the TAPP group. Postoperative morbidity was 2.8% in the emergency group and 3.8% in the chronically incarcerated group, which does not differ from the rate for TAPP used on reducible hernias. One recurrence was found 26 months after TAPP reconstruction (0.5%). CONCLUSION: Laparoscopic inguinal hernia repair (TAPP) represents an efficient therapeutic concept in the treatment of both chronically and acutely incarcerated inguinal hernias.

Preperitoneal gridiron hernia repair for inguinal hernia: single-center experience with 2 years of follow-up.

The optimal operation technique for groin hernia repair has not been established. This study evaluates the long-term recurrence rate and perioperative complications after posterior inguinal mesh hernia repair using a gridiron incision described by Frans Ugahary. A retrospective analysis was performed of the medical records of 366 patients who underwent Ugahary hernia repair. Operative results and perioperative morbidity were evaluated retrospectively. Follow-up was done by clinical examination. The main outcome measure was recurrence rate at a mean follow-up of 2 years. Of the 386 groin hernia repairs, 263 hernia repairs were examinated in the outpatient clinic. The overall recurrence rate was 6.5% with a mean follow-up of 2 years, and 10.1% of the patients had minor complications. This retrospective study demonstrates that the repair according to Ugahary is a safe technique for operating on groin hernia. However, the procedure is difficult to reproduce in nonexpert hands. This technique must be compared to other inguinal hernia operation techniques in the near future.

Umbilical hernia repair with the prolene hernia system.

BACKGROUND: Despite its extensive application for the repair of inguinal hernias, the use of the Prolene Hernia System (PHS; Ethicon, West Somerville, NJ) for the repair of umbilical hernias has been sparse. The purpose of this prospective study was to assess, in comparison with currently available techniques, the effectiveness of the PHS in repairing umbilical hernias. METHODS: Fifty consecutive patients diagnosed with a primary umbilical hernia were enrolled for the study. They were randomized and underwent elective repair of umbilical hernia using either the PHS (n = 17), Mayo repair (n = 18), or onlay repair with mesh (n = 15). Data for the time required for the surgical repair method, length of hospital stay, postoperative pain, analgesic necessity, and return to work, and early and late complications were recorded, and compared with respect to the repair procedure. RESULTS: The mean operating time and the mean length of hospital stay were the longest in the onlay repair with mesh group (P < .05). Those patients operated on using the PHS described minimum pain on the postoperative first , second, and seventh days (P < .05) and also the necessity of analgesic was significantly lower in this group (P < .05). There were 2 recurrences in Mayo repair group. The mean follow-up duration was 22 months (range 6 to 44 months). CONCLUSION: The PHS seemed to be useful for umbilical hernia repairs in selected patients as it caused minimal postoperative pain and less analgesic necessity.
