Giant mature cyst formation following mesh repair of hernias: An underreported complication?

Mesh Antibioma: A New Entity in the Presentation of Late-Onset Mesh Infection

Antibioma is a tough-walled abscess, which usually forms as a sequela of inadequate or lack of pus drainage during infection and inappropriate use of antibiotics by the patient. In this case report, we present a case of the development of antibioma due to infected polypropylene mesh used in umbilical hernia repair 10 years ago in a 59-year-old obese male. He had a history of umbilical and right inguinal hernioplasty 10 years back. Intraoperatively, we found antibioma whose wall was made up of fibrous mesh and the center was filled with pus and nonfibrous mesh remnants. The pus was found to be sterile, and the wall was made up of fibromuscular adipose tissue with chronic inflammatory cells around it. This is a very rare presentation of umbilical site deep mesh infection as it had no signs of acute inflammation, neither pain nor any pus discharge. We conclude that the possible explanation for the formation of antibioma and its very delayed presentation could be due to mesh infolding and seroma/hematoma formation during previous surgery may have led to the formation of abscess and thick fibrous wall without any fistulous tract and other complications of deep mesh infection.

Plastic Treatment for Giant Pseudocyst after Incisional Hernia Mesh Repair: A Case Report and Comprehensive Literature Review

Giant pseudocyst is a very rare complication after incisional hernia repair with mesh. We present a case of 54-year-old male patient with a giant pseudocyst, which developed after incisional hernia repair with mesh. A patient was discussed during multidisciplinary team meeting and operative treatment was suggested to the patient. Extirpation of the cyst was accomplished. There was observed no defect in the abdominal wall. The patient was discharged on the 7th postoperative day. Ultrasonography two weeks after discharge again showed fluid collection. There were 6 aspirations every week starting from 400 ml serous fluid at the beginning and 60 ml at the end. There were no signs of fluid collection one month after the last aspiration. Surgical plastic treatment of giant pseudocyst after incisional hernia mesh repair is safe and feasible despite its low prevalence.

Laparoscopic Fenestration of a Giant Pseudocyst after Totally Extra Peritoneal Inguinal Hernia Repair

A giant pseudocyst is a rare complication after hernioplasty and is seldom seen. The pathophysiology is unclear; it characteristically does not contain epithelial lining and can be considered giant if the diameter exceeds 10 cm. Pseudocysts are mostly described after incisional hernia repairs and are usually treated with surgical resection. We report a case of a giant pseudocyst three years after totally extra peritoneal inguinal hernia repair. Laparoscopic fenestration without removing the pseudocyst with or without removal of the polypropylene mesh is a safe and effective minimal invasive approach to the treatment of a symptomatic pseudocyst and should also be considered in the approach of other large symptomatic cysts.

Persistent inguinal seroma managed with sprinkling of talcum powder: a case report

Introduction

We present a new method to treat recurrent seromas, which is based on our experience with a patient who had recurrent groin seroma and was treated successfully with a sprinkling of talcum powder in the seroma cavity.

Case presentation

A 67-year-old Caucasian man with a suprapubic recurrent right groin hernia underwent inguinal hernioplasty with a polypropylene plug. Three days later the patient presented with a right groin fluctuating mass beneath the surgical wound with no signs of infection, and was discharged after seroma aspiration. After 23 days of increasing drainage, the seroma cavity was thoroughly dried with clean gauze swabs, and four g of sterilized dry talcum powder was sprinkled into the seroma cavity with a five-cc syringe. A compressive dressing was placed, and the patient was discharged. One week after the sprinkling of talcum powder, the surgical wound was almost closed with only minimal oozing from the drainage incision. The patient did not report any adverse effects. Two weeks later, the wound was fully healed.

Conclusion

Talcum powder sprinkling could be an effective, quick, and safe method for the treatment of inguinal seromas after inguinal hernioplasty when conservative management has failed. Nevertheless, larger series are needed before assessing this technique as the treatment of choice.

First cases of giant pseudocyst complicating inguinal hernia repair

INTRODUCTION

Giant pseudocyst is a rare type of complication following incisional hernia repair and its correct management is still unknown.

MATERIALS AND METHODS

Herein, we describe two unreported cases of giant pseudocyst after inguinal hernia repair. Both patients underwent surgical treatment with partial excision of the pseudocapsule. The two patients were free from recurrence after 6 and 10 months of follow up, respectively.

CONCLUSION

Subtotal surgical removal of the pseudocapsule is a definitive treatment.

Abdominal pseudocyst complicating incisional hernia repair: our experience and literature review

Giant pseudocyst is a rare complication of incisional hernia repairs whose etiology and incidence remains unknown. We have reviewed all cases of abdominal incisional hernia repair in our abdominal wall unit since its creation 6 years ago. Pseudocyst formation was observed in seven cases out of 871 incisional hernia repair operations. Four of them underwent surgical exploration with excision of the mass. To the best of our knowledge, only 18 cases of giant pseudocyst have been described in the literature. From both our personal experience and the reported literature, we understand that abdominal pseudocyst is an extremely rare or underreported late complication of hernia repair surgery. The complete excision of the cyst and its fibrous wall is the definitive treatment of choice.

[Late complication after mesh repair of incisional hernias: pseudocyst formation]

INTRODUCTION

Using mesh for hernia repair is a very common procedure; they are particularly useful for postoperative incisional hernias. The most common complications of mesh repair are seroma, haematoma or abscess formation. Previous literature data suggested that fibrotic cyst formation appearing in the late postoperative period is relatively rare. However, more recent studies and our own experience indicate that its incidence is more common and we have to consider it in the differential diagnosis of the complications of hernia repair.

PATIENTS

148 incisional hernia mesh repairs were carried out between a period of 1st January, 2001 to 31st December, 2005. Fibrotic pseudocyst formation was observed in five cases. All developed as a late complication between 4 to 25 months postoperatively. An onlay polypropylene mesh was used in each case. All five patients underwent a wide excision of the pseudocyst wall and they recovered without complications.

DISCUSSION

The etiology of pseudocyst formation is unclear. Nevertheless, a possible relationship between the development of seroma and haematoma can not be ruled out, despite no fibrotic pseudocyst formation was observed in the early postoperative period. There is no evidence whether the characteristics of the mesh or the way of implantation would have any effect on pseudocyst formation, as well. It is noted that the only treatment of this late complication is surgical excision. Pseudocyst formation might be prevented by the application of sublay and minimally invasive techniques.

Giant pseudocyst of the anterior abdominal wall following mesh repair of incisional hernia: a rare complication managed laparoscopically

Giant pseudocyst formation of the anterior abdominal wall, following on-lay polypropylene mesh repair for incisional hernia is an under reported complication. We report an unusual case of a 56-year-old female who underwent a polypropylene mesh repair of incisional hernia 2 years back. Subsequently she developed a giant pseudocyst of the anterior abdominal wall, which was occupying the whole of the abdomen from the xiphisternum to the pubic bone, and over both the flanks. Over a period of one year, the cyst had defied multiple attempts at aspiration. The patient underwent a laparoscopic drainage of the collection with piecemeal excision of the entire cyst wall. Histopathology of the cyst wall revealed necrotic material with intervening areas of hemorrhage. No epithelial lining was seen. There has been no recurrence in the two years of follow-up.

CONCLUSION

giant pseudocyst of the anterior abdominal wall is a rare complication following mesh repair of an incisional hernia. Such pseudocysts can be managed successfully by laparoscopic procedures.

Two cases of cystic seroma following mesh incisional hernia repair

Cystic seromas, or mature fibrous cysts, are rare complications after ventral and incisional hernioplasties employing polypropylene mesh. We analyzed the medical records of patients, whose abdominal-wall hernias were surgically repaired with polypropylene mesh from November 1996 to February 2004 (N=685). Of the 162 patients, who had incisional hernias repaired with the Rives technique (preperitoneal mesh), we detected two patients who developed giant cystic seromas. Both patients underwent surgical resection of the cyst wall. As follow-up care improves for patients undergoing hernioplasties with polypropylene meshes, more cystic seromas are detected, thereby improving our knowledge of the clinical, radiological, and histopathological characteristics of this complication. However, the etiologic factors related to the appearance of this chronic cyst remain uncertain.
