Case reports: Online first

Morgagni hernias are unusual diaphragmatic hernias which usually present in adulthood. They have traditionally been repaired through transabdominal or transthoracic approaches. The authors present a case of a laparoscopic repair of a Morgagni hernia in a 52-year-old female. A tension free repair of the defect was accomplished utilizing Goretex (W.L. Gore & Associates, Inc., North Elkton, MD) mesh. The patient had an uneventful recovery and is asymptomatic at 6 months follow-up. The etiology, diagnosis and traditional surgical approaches to this problem are discussed. A technique for laparoscopic repair of a Morgagni hernia is described. The literature on the laparoscopic repair of a Morgagni hernia is reviewed and different operative techniques are discussed.     

The Laparoscopic Approach for Repair of Morgagni Hernias

Background and Objectives:

Morgagni hernias are unusual congenital diaphragmatic hernias that are generally asymptomatic and discovered incidentally. Surgical treatment is indicated once the diagnosis is made. These hernias have traditionally been repaired by the open abdominal or thoracic approaches. We report a case of Morgagni hernia repaired successfully via the laparoscopic approach.

Methods and Results:

The patient was noted to have a large anteromedial diaphragmatic hernia by chest radiograph and CT imaging. He underwent laparoscopy, during which the hernia was reduced and the defect repaired with mesh placement. We used intracorporeal suture placement to anchor the mesh. The patient recovered uneventfully after a short hospitalization.

Conclusions:

The laparoscopic approach for repair of Morgagni hernias offers diagnostic advantages as well as the potential for reduced morbidity when compared to laparotomy. We report intracorporeal knot-tying for fixation of the mesh to be a secure and satisfactory means to achieve the laparoscopic repair.     

Congenital diaphragmatic hernia in adults

Congenital diaphragmatic hernia is rarely seen in adults. A review of the literature is presented, and 2 additional cases of Morgagni and Bochdalek hernias are presented. They were both repaired with the laparoscopic approach.     

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.     

Laparoscopic repair of a morgagni hernia in a child: a case report

Morgagni hernias are anomalies of the sternal insertions of the diaphragmatic bundles and represent 1% to 4% of all surgically treated diaphragmatic hernias. We present a case of a laparoscopic repair of Morgagni hernia incidentally found in a 4-year-old boy. Primary laparoscopic closure of the defect with interrupted silk sutures was performed. The patient had uneventful recovery and is asymptomatic at 2 months of follow-up. We propose that the laparoscopic approach is feasible and effective treatment of this kind of hernia.     

Laparoscopic repair of a Morgagni-Larrey hernia

Morgagni-Larrey hernia is a congenital type of diaphragmatic hernia. It is quite uncommon, particularly when it occurs on the left side of the diaphragm. This is a report of a case of a large left-side diaphragmatic hernia through the foramen of Morgagni treated by laparoscopy. The hernia was repaired by incorporating and fixing a polypropylene double-filament mesh into the defect, leaving the sac in mediastinum. The patient recovered promptly after the hernia repair, and there was no recurrence or complaints 30 months after surgery. Our conclusion is that laparoscopically repairs of Morgagni hernias with a prosthetic material are a safe and effective treatment. A literature review also shows that laparoscopic techniques are the gold standard in diaphragmatic hernias repairs.     

Morgagni’s Hernia: Analysis of 21 Patients with Our Clinical Experience in Diagnosis and Treatment

A Morgagni’s hernia is a congenital defect found in the anterior aspect of the diaphragm between the costal and the sternal portions of this muscle. This defect is also referred to as the space of Larrey. It has been reported that 70% of patients with Morgagni’s hernia are female, 90% of the hernias are right-sided, and 92% of the hernias have hernia sacs. This type of hernia is a rare clinical entity and accounts for 3% of all surgically treated diaphragmatic hernias. There are no large retrospective or prospective studies on this topic. This type of hernia is a rare type among adults without a well-described prevalence and without well-established definitive management strategies. There are also few clinical reports about this clinical entity and its surgical treatment. We treated 21 patients with Morgagni’s hernia in a 12-year period, and we report our experience while discussing the surgical treatment of this disease. We performed a retrospective review of the 21 patients who were operated between 2003 and 2015. These patients had undergone surgical repair of Morgagni’s hernia. For each subject, demographic data, symptoms of presentation, physical examination findings, preoperative imaging studies and diagnosis, and surgical procedures were documented. Location of the hernia sac and its contents, postoperative complications, and duration of hospital stay were recorded and evaluated. Twelve patients were females and nine were males. The mean age of patients was 63.85 years. Dyspnea was the most prominent symptom in our patients. Morgagni’s hernias were located on the right side in 19 patients and on the left side in 2 patients. Chest X-ray in 10 patients and abdominal computerized tomography in 17 patients were the major diagnostic tools. Four patients were operated as emergency while others underwent elective surgery (17 patients). Twelve patients were operated with laparoscopy and the remaining nine were operated with the conventional open abdominal technique. Hernia sacs were observed in all of the patients and removed except in four of them. The omentum and the transverse colon were the most commonly seen organs in hernia sacs. Hernia defects were repaired with primary sutures in four patients (all open cases) and primary closure supported with mesh in six patients (four laparoscopic, two open cases). In the remaining 11 patients, hernia defects were closed with synthetic meshes (eight laparoscopic, three open cases). Mean postoperative hospital stay was 9.8 days. No recurrence was observed in any patients. Only one of our patients died during follow-up. In Morgagni’s hernias, surgical intervention is necessary as the hernia may cause complications such as strangulation of the colon or intestines. A laparoscopic approach has increased its popularity in recent years because of the well-known advantages of laparoscopy.     

Foramen of Morgagni hernia: changes in diagnosis and treatment

BACKGROUND: Foramen of Morgagni hernias are uncommon diaphragmatic hernias for which there are limited reported data. The purpose of this study is to report a recent case series of foramen of Morgagni hernias in the context of new diagnostic and treatment modalities. METHODS: A retrospective chart review was performed over a 15-year period, from 1987 to 2001. Twelve patients who had a foramen of Morgagni hernia repaired at our hospital were identified, and data from these patients were collected. RESULTS: The average age at treatment was 45 years, with 50% of patients being asymptomatic. Radiographic evaluation included computed tomography scans in two thirds of the patients with a 100% sensitivity for diagnosis. All hernias were right-sided, and the most common contents of the hernias were omentum and colon. The transabdominal route was the preferred surgical approach. Thoracoscopy was used in 2 patients to further characterize a mediastinal mass. Two patients underwent laparoscopic repair. Postoperative complications were infrequent, and there were no recurrences during a 6-month to 10-year follow-up. CONCLUSIONS: The emergence of highly accurate diagnostic computed tomography scans combined with less invasive surgical techniques utilizing laparoscopy and thoracoscopy has aided in the treatment of foramen of Morgagni hernias over the last 15 years.     

Laparoscopic repair of congenital bilateral Morgagni hernia

Morgagni hernia is a rare type of congenital diaphragmatic hernia found in the anterior aspect of the diaphragm. It typically presents in the pediatric population and rarely is diagnosed in adults. Only 3% of diaphragmatic hernias are the Morgagni type, and only 4% of these are found to present bilaterally. Surgical repair of Morgagni hernia has been performed through various approaches including open, laparoscopic, thoracotomy, and video-assisted thoracoscopic surgery (VATS), all with and without mesh. The optimal method of surgical repair is not known due to the rarity of this condition and the limitations of setting up a prospective, randomized trial to evaluate the different methods. Laparoscopic repair with mesh has been described with good short-term results. Few case reports exist in the world literature describing laparoscopic repair of a bilateral Morgagni hernia with mesh. At the University of Washington, the authors present a video showing their technique for laparoscopic repair of a congenital, bilateral Morgagni type hernia with mesh.

Laparoscopic repair of congenital diaphragmatic hernias

Bochdalek and Morgagni hernias are the least common congenital diaphragmatic hernias, with the prevalence of Bochdalek hernia being 1/2200 births and the prevalence of Morgagni hernia being 1/1 million births. Although they are usually asymptomatic, congenital diaphragmatic hernias, especially Bochdalek and Morgagni hernias, are diagnosed in early childhood. In adulthood, they are diagnosed incidentally or when they become symptomatic. The repair of congenital diaphragmatic hernia is indicated in all children and symptomatic adults. We present three cases of congenital diaphragmatic hernia, two Morgagni and one Bochdalek hernias, repaired laparoscopically. We describe the operational methods. The results of the operations were satisfactory, with cure defined with radiological images after 1 month. We propose the use of laparoscopy in the repair procedure because it is a safe and effective method. Benefits include that it provides an excellent view of the surgical field, ease of execution, minimal surgical trauma, excellent cosmetic results, rapid recovery, and shorter hospitalization stay.     

Transabdominal Approach in the Surgical Management of Morgagni Hernia

Purpose Morgagni hernias are uncommon diaphragmatic hernias that are generally asymptomatic, and so far only limited data have been reported. The objective of this retrospective study was to evaluate the outcome of patients presenting with a complicated Morgagni hernia and who undergo a transabdominal repair. Methods Between September 1999 and October 2005, 11 patients with Morgagni hernia were operated on in our department. Eight of them had acute presentations because of a complicated Morgagni hernia. The patient demographics, presenting symptoms, operative approach, and complications were collected. The postoperative course was evaluated for morbidity and mortality. Results The patients' ages ranged from 42 to 85 years (mean 69.4). Two (18.2%) patients were male and nine (81.8%) patients were female. Chest roentgenograms, computed tomography, and contrast meal studies were used as diagnostic utilities. A transabdominal approach was used for all patients. One patient died due to pulmonary failure. The mean follow-up was 2.8 years. There was no recurrence or symptoms regarding the operation in the remaining patients. Conclusion We recommend the transabdominal approach in patients with Morgagni hernia as it makes it easy to reduce the hernia contents and repair of the hernia sac. Moreover, when complicated with strangulation, incarceration or perforation, a surgical repair through a transabdominal approach is mandatory.     

Use of a prosthetic patch for laparoscopic repair of Morgagni diaphragmatic hernia in children

BACKGROUND: Morgagni hernias are well suited to laparoscopic repair. A primary suture closure may result in tension on the repair, thereby predisposing the patient to a recurrence. A prosthetic patch (PP) can be used to provide a tension-free repair. In this study, we reviewed our experience with the laparoscopic PP repair of Morgagni hernias in children. METHODS: A retrospective chart review of all patients undergoing a laparoscopic Morgagni hernia repair using a PP was undertaken between November 2002 and January 2006. Outcome measures included age, gender, defect size, use of mesh, and outcome. The time of follow-up was from 6 to 37 months. RESULTS: Seven (7) patients (6 male, 1 female) underwent a laparoscopic repair of Morgagni hernia during this time period. Six (6) patients had a congenital hernia, and 1 patient was thought to have an iatrogenic hernia following a sternotomy for heart surgery. Defect size ranged from 4 to 7 cm in maximum dimension. All operations were completed laparoscopically, no patients presented with recurrence, and no PP complications were encountered. CONCLUSIONS: The laparoscopic repair of Morgagni hernia using a PP can be performed with relative ease and with a positive outcome, and may prevent future recurrence by effecting a tension-free repair.     

Laparoscopic tension-free repair of large paraesophageal hernias

The paraesophageal hernia is an unusual disorder of the esophageal hiatus that may be associated with life-threatening mechanical problems. Elective repair is recommended at the time the condition is diagnosed, and open surgery can be accomplished with a low incidence of complications. The option of performing these repairs through a laparoscopic approach may further reduce morbidity and recovery time associated with surgical intervention. The purpose of this report was to review available options for laparoscopic repair and to present our experience with a tension-free technique for large paraesophageal hernias. Three patients with large diaphragmatic defects had laparoscopic repairs using an expanded polytetrafluorethylene (PTFE) patch secured with intracorporeal suturing techniques. One of these patients also underwent laparoscopic Toupet fundoplication in conjunction with repair of the hernia. In the other two patients, the fundus was secured to the right diaphragmatic crus to reduce the potential for recurrence and minimize postoperative reflux symptoms. All patients underwent successful repair without perioperative complications and had excellent long-term results. Laparoscopic repair of paraesophageal hernias can be accomplished by a number of different reported techniques. The use of a tension-free repair with PTFE may be particularly suitable for large diaphragmatic defects. An antireflux operation may be added selectively depending on clinical circumstances.     

Laparoscopic repair of Morgagni hernia

BACKGROUND: Morgagni hernia is a rare type of diaphragmatic hernia which represents less than 5% of all congenital diaphragmatic hernias. Patients are generally asymptomatic and are diagnosed incidentally. When symptomatic, it generates symptoms due to the compression of thoracic organs or compression of herniated intraabdominal organs. Once diagnosed, the condition requires prompt surgical correction. The defect is repaired either by primary suture or by the use of a prosthetic mesh. In adults, prosthetic mesh repair is preferred. Recently, laparoscopic repair of Morgagni hernia has been introduced and gained wide acceptance. MATERIALS AND METHODS: Between 2002 and 2004, 5 patients with Morgagni hernia were treated laparoscopically at our department. Female/male ratio was 3/2. Mean age was 56 years (range 41 to 69 y). Diagnosis were made by chest x-ray and CT scan. Herniation was on the left in 2 patients, and on the right in 3. The content of hernial sac was transverse colon and stomach. There were 2 separate defects in a patient with left-sided hernia. All cases were laparoscopically treated using prosthetic material. RESULTS: All operations were completed laparoscopically. The postoperative hospital stay was 3 to 5 days with a mean of 4 days. None of the patients developed any complication in the early postoperative period. The mean follow-up period is 7 months (range 3 to 24 mo). All patients are actually in good health and without recurrence. CONCLUSION: Laparoscopic repair of Morgagni hernia is a safe, simple, and reliable procedure which presents all the advantages of the minimally invasive surgery.     

Presentation and management of Morgagni hernias in adults: a review of 298 cases

Background  Morgagni hernias are a very rare form of diaphragmatic hernias. No robust studies have been performed to show the true natural history of this disease process. This study aimed to summarize clinically relevant data with respect to Morgagni hernias in adults. These data should help surgeons workup, diagnose, and treat Morgagni hernias in adult patients. Methods  A literature search was performed using PubMed, Google scholar, and the following key words: Morgagni, Larrey, retrosternal, retrocostoxiphal, retrochondrosternal, parasternal, substernal, anterior diaphragmatic, and subcostosternal. All case reports and series after 1951 that pertained to adults were included in the review. The following data points were queried: age, sex, presentation, studies used during workup, laterality, surgical approach, hernia sac management, specific laparoscopic techniques, and follow-up evaluation. Results  These criteria were met by 135 articles representing 298 patients. Based on the data provided, several conclusions regarding this disease process can be drawn. Most patients (72%) present with symptoms related to their hernia. Pulmonary complaints are the most common symptoms (36%). Men present earlier in life than women. Thoracotomy is the most widely used surgical approach (49%). However, laparoscopic repair has gained popularity since its first report in 1992. Laparoscopic surgeons usually repair the defect with mesh (64%) and do not remove the hernia sac (69%). Laparoscopic repair can be performed with a low complication rate (5%) and a short hospital stay (3 days). Outcomes of other surgical approaches also are reported. Conclusions  Using modern surgical techniques including laparoscopy, repair of Morgagni hernia can be performed safely with a short hospital stay and with little morbidity or mortality.

Technical description of laparoscopic Morgagni hernia repair with primary closure and onlay composite mesh placement

Introduction

Morgagni hernias rarely present in adult life and, thus, little data exist on the optimal method of surgical repair. The laparoscopic approach has grown in popularity since the first reported case in 1992. This article showcases a method for laparoscopic repair of Morgagni hernias using both primary closure and mesh reinforcement.

Operative approach

There were three obese women who presented in adulthood with cardiopulmonary symptoms; in all cases, the symptoms were attributable to local compressive effects of large Morgagni hernias. All three hernias were repaired laparoscopically, first by approximating the diaphragm to the fascia of the anterior abdominal wall, followed by insertion of a composite mesh, tacked to the diaphragm, to buttress the closure. All patients had excellent outcomes with symptom resolution.

Discussion

This case series describes a method of laparoscopic Morgagni hernia repair using primary closure reinforced with a mesh, with excellent postoperative outcomes. Others have described thoracic or open approaches. The authors feel that the method described herein is likely to reduce recurrence in a patient population who are often overweight or obese and, thus, have a high risk of this complication. Furthermore, we discuss all reported laparoscopic repair cases in the literature and highlight the paucity of evidence on the optimal approach.

     

Laparoscopic Incisional Hernia Repair in Liver Transplant and Other Immunosuppressed Patients

We report the early results of laparoscopic incisional hernia repair in a small group of immunosuppressed patients and compare these results with a cohort of patients with open repair. We describe a modification used to secure the cephalad portion of the Gore-Tex mesh in high epigastric incisional hernias often encountered after liver transplantation. Data were gathered retrospectively for all incisional hernia repairs by our group from March 1996 to January 2001. Twelve of 13 attempted patients had successful completion of their laparoscopic hernia repairs with no reported recurrences to date. Two of these procedures were performed for recurrent hernias. We completed nine of nine attempted laparoscopic hernia repairs in liver transplant patients with epigastric incisional hernias. We repaired two of three attempted lower midline incisional hernias in renal disease patients. One of these patients was soon able to reuse his peritoneal dialysis catheter. A total of 15 patients, 12 with liver transplants, underwent open repair of their incisional hernias. These patients had seven recurrences and/or serious mesh infections with five patients electing repeated operations. In our initial series, laparoscopic mesh repair of incisional hernias is practical and safe in the abdominal organ transplant population with a low incidence of early recurrence and serious infections.     

Laparoscopic reduction of an acute gastric volvulus and repair of a hernia of Bochdalek

We report a case of an acute strangulated gastric volvulus in a hernia of Bochdalek in an adult female patient that was repaired successfully via the laparoscopic approach. A left-sided diaphragmatic hernia contained a strangulated but viable gastric volvulus and a noncompromised colon. The contents of the hernia were reduced, and the 4-cm congenital diaphragmatic defect was primarily repaired with nonabsorbable sutures. The patient was discharged on the second postoperative day and remained symptom-free at 7 months. Unlike the very few previous reports of elective laparoscopic repair of uncomplicated Bochdalek hernias, this appears to be the first report of an urgent laparoscopic repair of a complicated hernia of this type.     

Laparoscopic repair of diaphragmatic hernias: experience of six cases

OBJECTIVE: Laparoscopic diaphragmatic hernia repair is increasingly performed in adults for congenital diaphragmatic hernias and chronic traumatic diaphragmatic hernias. This study reviewed our experience with laparoscopic diaphragmatic hernia repair to evaluate its safety, efficacy and outcomes. METHODS: Between January 1999 and December 2002, four male and two female patients presented to us with diaphragmatic hernias, three with traumatic and three with congenital hernias. The mean age of patients was 58.6 years (range, 42-83 years). Five patients presented with main complaints of postprandial retrosternal/chest discomfort and one patient had an acute gastric outlet obstruction. Dissection was performed laparoscopically to reduce the contents of the sac and the hernial defect was repaired using prolene sutures and a polypropylene mesh. RESULTS: Laparoscopic repair of diaphragmatic hernias was completed successfully in all patients. The mean size of the defect was 6.8 cm (range, 3-12 cm) and the mean operative time was 100 minutes (range, 60-150 minutes). There were no major intraoperative complications. One patient required placement of a chest tube due to inadvertent opening of the pleura with the hernial sac and one patient had prolonged postoperative gastric ileus. The mean hospital stay was 2.3 days (range, 1-4 days) and the mean pain score was 4 (range, 2-6). All patients remained asymptomatic over a mean follow-up of 2.9 years. CONCLUSION: Adult congenital and chronic traumatic diaphragmatic hernias are amenable to laparoscopic repair. Laparoscopic repair is safe and feasible and confers all the advantages of minimal access surgery.
