Discussion
Giant hernias are rare in present times. They are present due to neglect (Patsas et al. 2010). The use of local anesthesia for hernioplasty techniques that encourage patients to undergo an operation shortly after diagnosis leads to rare occurrence of giant inguinal hernia today. The patient may remain asymptomatic or present with acute renal failure, perforation with concomitant peritonitis (Goonetille et al. 2010 and Gaedecke et al. 2013). In such giant hernia, ulceration, dermatitis, or candidiasis of scrotal skin could usually lead patients to seek medical care. There is a case report in which the incident of a gastric rupture in context with a giant left scrotal hernia has occurred (Walgenbach et al. 2001). Walking, sitting, simply lying down, and voiding may become extremely difficult for the patient. Penis could be buried, and only one testicle could be palpated. Usual content is gut, and sometimes the entire mesenteric small bowel and the entire colon may be lodged appendix, omentum, or bladder (Conda Sanchez et al. 2001 and Tahir et al. 2008). Rarely malrotated intestine could be present in a giant inguinal hernia (Lee 2012).
Due to rarity of condition, repair of giant inguinal hernia is always challenging, demanding to the surgeon, and stressful to the patient. Surgical management has to be tailored to the individual situation of the patient using all therapeutic options (Zippel et al. 2001). Loss of domain, recurrence and residual scrotal skin, and scrotal hematoma are the major problems encountered in management of such hernias (Coetzee 2011). A proper preoperative preparation for surgery in patients with giant hernias is desirable, especially involving respiratory status.
In elective repair, preoperative use of progressive pneumoperitoneum is effective in the treatment of large inguinal hernias (Piskin et al. 2010). Creation of pneumoperitoneum leads to optimal space for reduction of herniated contents into abdominal cavity and avoids abdominal morbidity in form of bowel resection, abdominal compartment, and extended abdominal wall reconstruction by the use of mesh (Vasiliadis et al. 2010). Laparoscopic component separation technique has been recommended to increase the capacity of the abdominal cavity to facilitate closure and reduce postoperative complications in patients who had loss of domain (Hamad et al. 2013).
El-Dessouki (2001) presented a technique for giant inguinal hernia in which hernia sac is pulled up to the abdomen and fashioned as a rotation flap to augment and close the peritoneum over the replaced contents; a giant polypropylene mesh is inserted in the preperitoneal space to cover the midline defect created and to buttress both inguinal regions. Zuvela et al. (2003) described the Rives technique (direct inguinal approach) in the treatment of large inguinoscrotal and recurrent hernias. Merret et al. (2009) advocated a technique for giant inguinal hernia involving the reduction of hernia; the repair of hernial orifices with Marlex mesh and the creation of a midline abdominal wall defect to increase the intra-abdominal capacity followed by covering this defect with Marlex mesh with a rotation flap of inguinoscrotal skin. Lichtenstein technique has also been advocated for repair of giant inguinal hernia (Bierca et al. 2013). A multistage operation for giant inguinal hernia with scrotal ulcer has been recommended where insufflation and prosthetic mesh are not available. In first stage, resection of ulcer and surrounding scrotal skin and partial reduction of hernia sac content are done. Partial reduction of hernia sac contents and resection of scrotal skins are done in stage two. In the last stage, bowel resection, ileocolic anastomosis, hernia repair, and resection of scrotal skin are done (Groen et al. 2011).
In an emergency, surgical treatment of giant abdominal hernias includes reduction of the hernia content and tension-free closure of the abdominal wall. Surgical treatment in complicated cases may require debulking the contents of the hernia sac by performing a right hemicolectomy and a small bowel resection and reconstruction of the abdominal wall using Marlex mesh and a tensor fasciae latae flap (Mehendal et al. 2000 and Goonetilleke et al. 2010). Inguinal incision aided by midline infraumbilical incision aids in the reduction of contents into abdominal cavity in giant inguinal hernia (Tahir et al. 2010).
Conclusion
Giant inguinal hernia presenting as intestinal obstruction is rare. Reduction of contents into abdominal cavity in giant inguinal hernia may be done by enlarging internal ring.
