Incisional hernia after extreme lateral interbody fusion on the lumbar spine: A case report

IntroductionExtreme lateral interbody fusion is a minimally invasive lateral transpsoas approach for spine surgery. We herein report a case of an incisional hernia after an extreme lateral interbody fusion on the lumbar spine that was successfully treated by laparoscopic surgery with intraperitoneal onlay mesh repair.Presentation of caseA 78-year-old woman was referred to our hospital with a complaint of left abdominal bulge and pain. She had undergone an extreme lateral interbody fusion for a lumbar spinal canal stenosis from L1 to L4 a year prior. Abdominal computerized tomography showed a left lumbar incisional hernia, and laparoscopic surgery was performed. The hernia orifice was sutured closed and covered with mesh. The patient was discharged five days after the operation with no complications.DiscussionWhen performing XLIF for a spinal disorder, the muscles should be separated bluntly along their fibers to prevent muscle atrophy, and the incised fascia should be securely sutured closed. Abdominal wall incisional hernias can occur after spinal surgeries such as extreme lateral interbody fusion.ConclusionLaparoscopic repair for abdominal wall incisional hernia after spine surgery is safe and feasible.     

Complete mesh migration into the small bowel after incisional hernia repair: a case report and literature review

Introduction: Mesh migration into the intestine is very rare after incisional hernia repair.

Case report: We report the case of transmural mesh migration from the abdominal wall into the small bowel presenting as recurrent small bowel obstruction 18 years after repeated surgical repair of an incisional ventral hernia. At surgery, a mesh was found inside the resected ileal loop.

Discussion: Mesh migration into the intestine is a possible, although very rare, complication after incisional hernia repair with nonabsorbable meshes. It tends to occur late with obstructive symptoms, especially if the small intestine is involved. Avoiding the direct contact between the mesh and the intestinal wall may help to reduce this complication.

Central perineal hernia mimicking rectocele: a case report

Background A perineal hernia is a very rare clinical finding. Three forms are distinguished: anterior, posterior, and central. Diagnosis of the last one is difficult, and sometimes, it is falsely named a posterior rectocele. Aim This work presents a successfully treated case of central perineal hernia and makes a brief summary of existent literature on the problem. Presentation of the case We report of a 67-year-old female patient with a symptomatic central pelvic floor hernia. After radiological confirmation of the diagnosis, a transperitoneal approach was chosen to reposition the protruded segment of the small bowel. The hernial orifice was closed by extraperitoneal implantation of a polypropylene mesh. Discussion In the present case, the use of a laparoscopic technique seemed unsuitable due to the extension of the findings. For the repair of perineal hernia, we followed the principles of the “tension-free” concept. If there are no signs of a pelvic floor infection and if the mesh can be implanted totally extraperitoneally, we recommend the use of nonabsorbable alloplastic material (polypropylene) for reinforcement of the pelvic floor as a suitable technique for the repair of large perineal hernias.     

Laparoscopic repair of congenital diaphragmatic hernia with prosthesis: a case report

We report here our experience in the treatment of a large congenital diaphragmatic hernia, an uncommon pathology, approachable by laparoscopy. The patient was a 33-year-old woman with trisomy 21 syndrome, who only complained of colicky abdominal pain and a cough for 7 months before the hospitalization. Thoracic and abdominal CT scans showed a large anteromedial diaphragmatic hernia with slippage of the colon into the mediastinum and posterior displacement of the cardiovascular structures. The patient underwent laparoscopic repair of the hernia. The colon was put back in the abdomen; the defect (8×4 cm) was repaired by a Composix mesh (PTFE-polypropylene), fixed to the diaphragm by nonabsorbable stitches and staples. The patient was discharged on the third postoperative day. The postoperative course was uneventful. Follow-up at 18 months didn't show any complications or recurrence. We believe laparoscopic repair of diaphragmatic hernia to be the elective surgical choice, because of its technical feasibility and certain intra- and postoperative advantages.

A minimally invasive treatment of an asymptomatic case of mesh erosion into the caecum after total extraperitoneal inguinal hernia repair

Background: Mesh migration and erosion into adjacent viscera is a rare complication after laparoscopic inguinal hernia repair. We present a minimally invasive treatment of an asymptomatic case of mesh erosion into the caecum after total extraperitoneal inguinal hernia repair, including an overview of the relevant recent literature.

Methods: A male patient underwent a laparoscopic inguinal hernia repair at the age of 42. Two years after this procedure, a screening colonoscopy revealed erosion of the mesh into the caecum. A laparoscopy was performed with partial resection of the mesh and minimal resection of the involved colon. Results of a systematic review of English PubMed articles on mesh migration and erosion after inguinal hernia repair is presented.

Results: We report a first-time minimally invasive treatment of mesh erosion into the colon. A laparoscopic approach is feasible and provides an excellent exposure. Partial removal of the mesh is suggested in uncomplicated cases to avoid complications associated with complete mesh removal.     

Chronic inguinal pain after laparoscopic intraperitoneal onlay mesh (IPOM) repair for inguinal hernia treated successfully with laparoscopic selective neurectomy: A case report

IntroductionLaparoscopic intraperitoneal onlay mesh (IPOM) repair is occasionally used for inguinal hernia repair. Here, we report a case of chronic neuropathic pain after laparoscopic IPOM repair for inguinal hernia, which was treated successfully with laparoscopic selective neurectomy.Presentation of caseA 59-year-old man with bilateral inguinal hernia underwent laparoscopic repair. Transabdominal preperitoneal repair was performed on the left side, whereas IPOM repair was performed on the right side due to a peritoneal defect. At postoperative month 1, he presented with severe pain and numbness distributed from the right inguinal region to the inner thigh region. The symptoms had persisted for 1 year despite medical treatment. We diagnosed that the symptoms might be due to the entrapment of nerves in the contracted mesh, and performed a second surgery via laparoscopic approach 13 months after the first surgery. On laparoscopic exploration, the lateral side of the mesh was contracted and involved nerve branches. We ligated and cut off these nerve branches. His symptoms resolved immediately after the surgery. At postoperative month 12, he has passed without any pain, numbness, and hernia recurrence.DiscussionLaparoscopic exploration would be useful to figure out chronic neuropathic pain after laparoscopic inguinal hernia repair.ConclusionLaparoscopic IPOM repair for inguinal hernia should be avoided as much as possible because it may cause chronic neuropathic pain. Laparoscopic selective neurectomy is an option for patients with chronic neuropathic pain after laparoscopic hernia repair.     

Multiple large enteroliths associated with an incisional hernia: a rare case

The surgeon frequently encounters renal and biliary stones but rarely may also encounter enteric stones or enteroliths. An enterolith is a stony foreign body that is formed in the gastrointestinal tract. We present a rare case of multiple, large enteroliths found associated with a longstanding incarcerated incisional hernia.     

Appendicitis in an incisional hernia after radical nephrectomy: a case report

Appendicitis is one of the most common surgical emergencies, and is usually diagnosed clinically on point tenderness in the right iliac fossa. The diagnosis can be difficult if there is abnormal anatomy. This case looks into the presentation of appendicitis within an incisional hernia secondary to radical nephrectomy. Appendicitis may present within hernias, and there should be a low threshold for computed tomography assessment of hernias when there is clinical doubt about the symptoms associated with the hernia.     

The lateral incisional hernia: anatomical considerations for a standardized retromuscular sublay repair

Background  The management of incisional hernias outside the midline remains a challenging procedure. Evidence-based data and even any kind of guidelines for dealing with this problem are still lacking. The aim of the study was to elucidate this field of hernia surgery and give some guidelines for retromuscular sublay mesh repair outside the midline. Materials and methods  Fresh-frozen corpses were used to perform anatomical studies. During all the investigations the main target was to find the layer which can maintain the maximum overlap of healthy tissue with the implanted mesh material. Afterwards the findings were evaluated during clinical situations, using photo-documentation and drawings. Results  The layer between the external oblique muscle and the internal oblique muscle is the ideal place to position the mesh with adequate overlap. Even for subcostal hernias, this layer offers adequate mesh overlap behind the ribs. For lumbar hernias the same plane of dissection is usually useful. Only if the defect is situated close to the bone might preperitoneal dissection and mesh placement be necessary. Conclusion  The repair of lateral hernias must follow the same principles as median sublay repair. With sufficient knowledge of the anatomical layers of the abdominal wall, adequate mesh overlap can be achieved for any kind of lateral hernia. Therefore the retromuscular sublay repair can be regarded as the standard procedure for all types of hernia outside the midline.     

腹腔镜下腹壁切口疝修补术(附41例报告)

目的探讨腹腔镜下采用聚丙烯和膨化聚四氟乙烯复合补片（Bard Composix Mesh）修补腹壁切口疝的效果。方法2004年10月～2005年8月，对41例切口疝（腹壁缺损长径3～25cm，宽径3～18cm）腹腔镜下用超声刀进行腹腔内粘连松解和采用强生疝修补用缝合器行补片固定修补术。结果41例均顺利完成，无中转开腹。手术时间60～182min，平均85min。术后疼痛轻微，术后排便、排气时间25～41h，平均32h。术后第2天进食。术后住院5～7d，平均6d。41例随访6～16个月，平均9个月，未见切口疝复发。结论腹腔镜下采用复合补片修补腹壁切口疝是一种安全、有效的方法，值得临床推广应用。     

Perforated caecal diverticulum as a content of inguinal hernia — report of a rare case

A tablet induced perforation of a caecal diverticulum into a hernial sac is a rare happening. The report discusses the presentation and outcome of a patient with such an unusual disease. A 55-year-old man presented with features of irreducible right sided indirect inguinal hernia. A hard swelling near upper pole of right testis was noted. Scrotal ultrasound revealed a normal testis. At operation caecum and proximal ascending colon were found in the hernial sac with the caecum adherent to the testis. As caecal malignancy could not be ruled out and enbloc Rt Haemicolectomy with Rt orchidectomy was performed. The patient had an uneventful recovery. Pathological examination of the specimen revealed a perforated caecal diverticulum with presence of multiple tablets in its lumen invaginating the upper pole of right testis without any evidence of malignancy. Tablet induced perforation of a caecal diverticulum into a hernial sac is a rare clinical entity. If malignancy cannot be negated at operation, a right haemicolectomy is a safe and feasible option.     

Bronchial leiomyoma in a chemical warfare victim-a causative agent or an incidental finding: A case report

INTRODUCTIONBronchial leiomyoma is one of the rarest benign tumors of the lower respiratory system, compromising less than 2% of reported benign pulmonary tumors. Chemical warfare is a known cause of chronic pulmonary diseases in soldiers who survives of the chemical wars. Most of these patients are chronically under treatment by respiratory drugs and acute exacerbations of their symptoms prompt for investigations for diagnosis of a new complication in these patients.PRESENTATION OF CASEIn this case report we present a 43 y/o male chemical warfare victim who was under treatment for his respiratory disease for near 20 years but at last bronchial leiomyoma was diagnosed as the cause of exacerbation of his symptoms. He was undergone right thoracotomy and sleeve resection of left main bronchus. Severe adhesions plus lymphadenitis in the mediastinum might be due to the effects of prior inflammatory process.DISCUSSIONBecause of rarity of this tumor, bronchial leiomyoma in this patient may be the result of previous exposure to nitrogen mustard but the exact relationship remained to be confirmed.CONCLUSIONAlthough the association between chemical warfare and lung neoplasias has not been well understood, it is the first time that a bronchial leiomyoma is reported in a nitrogen mustard survivor.     

Comparison of laparoscopic and open repair of incisional and primary ventral hernia: results of a prospective randomized study

Background Incisional hernia is an important complication of abdominal surgery. Its repair has progressed from a primary suture repair to various mesh repairs and laparoscopic repair. Laparoscopic mesh repair is a promising alternative, and in the absence of consensus, needs prospective randomized controlled trials. Methods Between April 2003 and April 2005, 66 patients with incisional, primary ventral and recurrent hernias were randomized to receive either open retrorectus mesh repair or laparoscopic mesh repair. These patients were followed up at 1-, 3-, and 6-month intervals thereafter for a mean of 12.17 months (open repair group) and 13.73 months (laparoscopic repair group). Results Lower abdominal hernias after gynecologic operations constituted the majority of the hernias (∼50%) in both groups. There was no significant injury to viscera or vessel in either group and no conversions. The defect size was 42.12 cm² in the open (group 1) and 65.66 cm² in the laparoscopic group (group 2), and the prosthesis sizes were, respectively, 152.67 cm² and 203.83 cm². The hospital stay was 3.43 days in open group and 1.47 days in laparoscopic group (p = 0.007). There was no significant difference in the pain scores between the two groups. More wound-related infectious complications occurred in the open group (33%) than in the laparoscopic group (6%) (p = 0.013). There was one recurrence in the open repair group (3%) and two recurrences in laparoscopic group (6%) (p = 0.55). Conclusions Laparoscopic repair of incisional and ventral hernias is superior to open mesh repair in terms of significantly less blood loss, fewer complications, shorter hospital stay, and excellent cosmetic outcome.     

Littre's hernia, an incarcerated ventral incisional hernia containing a strangulated meckel diverticulum: report of a case

Meckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract. Any hernia containing Meckel’s diverticulum is classified as a Littre hernia. Littre hernias typically occur in the inguinal region, and they may cause bowel obstruction secondary to strangulation or incarceration of the diverticulum within the hernial sac. This case appears to be the second reported of an incarcerated incisional hernia due to Littre’s hernia.     

An incidental finding of intraocular choristoma in an enucleated microphthalmic globe: A histopathologic case report

Introduction and importanceChoristomas are benign growth of normal tissue in abnormal location and in the ophthalmic practice, they are more commonly found in the epibulbar region. Intraocular choristoma has been reported in different ocular structures but it is very rare especially in association with microphthalmos.Case presentationWe present a 13-month-old child with bilateral microphthalmia with the left side being more significantly smaller than the right that required enucleation for introducing a larger silicone implant. The histopathological examination revealed an intraocular choristoma consisting of chondroid and adipose tissue with surrounding fibrosis. Other areas in the globe were also underdeveloped and dysplastic including the optic nerve, which was replaced by dense wavy collagen fibers and fibrovascular tissue.DiscussionEven though choristomas are benign, they may be extensive interfering with visual development especially the ones involving the epibulbar area.Systemic disease can have choristomas as an ocular feature such as in Goldenhar-Gorlin syndrome. Choristomas inside the eye are rare and they commonly involve the uveal tissue and the optic nerve head mostly in the form of ectopic glandular tissue and choroidal osseous choristoma. Our case is unique in its intraocular retrolental location, composition of chondroid tissue and fat, in addition to the fact that it was found within a microphthalmic globe with other interesting histopathological findings.ConclusionWe report a case of an incidental finding of intraocular choristoma with associated microphthalmia, genetic testing may be useful for establishing a genetic etiology in such cases even in the absence of dysmorphic features.     

Burkitt's lymphoma of the caecum as a rare cause of acute abdomen: a case report

Burkitt's lymphoma is a highly aggressive B-lymphoproliferative disorder. Clinically it most often manifests with extranodal involvement, typically affecting the gastrointestinal tract as a large and rapidly proliferating tumor mass, which may present as acute abdomen. We present a case report of a young man admitted with signs of acute appendicitis. A tumor of the ileocaecal junction was discovered perioperatively and resolved by a right-sided hemicolectomy. Histological examination of the tumor confirmed Burkitt's lymphoma. On the ninth postoperative day, the patient developed signs of ileus and a follow-up CT scan showed tumor masses in the area of the ileotransversoanastomosis. He was transferred to undergo radical adjuvant chemotherapy. Intestinal passage was restored during the next two days. Our aim is to report on the limited role of surgical treatment in this type of malignancy, due to the extremely rapid proliferation of the tumor tissue, when the tumor can grow back to its original size over a period of a few hours or days.
