ABSTRACT

INTRODUCTION: Extreme 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 CASE: A 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. DISCUSSION: When 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. CONCLUSION: Laparoscopic repair for abdominal wall incisional hernia after spine surgery is safe and feasible.

ABSTRACT

INTRODUCTION: Cryptorchidism or undescended testis is the most common disorder of male children, which is often diagnosed and treated during childhood. Adult patients with cryptorchidism are uncommon. Herein we report the case of adult inguinal hernia with cryptorchidism successfully treated by laparoscopic surgery simultaneously. PRESENTATION OF CASE: We report a case of 68 year-old-man who was admitted to our hospital with a complaint of bulge and pain in the right groin area from 2 weeks before. CT or MRI revealed a right inguinal hernia and an undescended testis in the right inguinal canal. He was diagnosed with right inguinal hernia accompanied by cryptorchidism. Laparoscopic transabdominal preperitoneal repair (TAPP) and orchiectomy were performed simultaneously. Postoperative period was uneventful and he was discharged home on the 1st postoperative day. Pathological examination of the specimen was reported as atrophic testis with no malignancy. There has been no recurrence during a follow-up. DISCUSSION: To our Knowledge, the case report of adult inguinal hernia with cryptorchidism treated by laparoscopic surgery is rare. All cases recommended the feasibility of laparoscopic surgery. CONCLUSION: Adult inguinal hernia with cryptorchidism is a rare condition. TAPP and simultaneous laparoscopic orchiectomy for inguinal hernia with cryptorchidism were safe and feasible. It could be the first surgical option for the treatment of such adult patients.

ABSTRACT

Mast-cell-development in the bone-marrow (BM) and the spleen is restrictedly controlled by stromal-cells which produce positive-regulators such as stem cell factor (SCF), and negative-regulators such as transforming growth factor-ß (TGF-ß). How the balance between positive- and negative-regulation is achieved or maintained by stromal-cells is not well understood. We intravenously injected 5-fluorouracil (5-FU) and lipopolysaccharide (LPS) into C3H/HeN mice to disrupt mast-cell-development in order to reveal mechanisms of mast-cell-regulation. 5-FU treatment induces a rapid decrease in the number of mast-cell-progenitor (colony-forming unit (CFU)-mast) cells in the BM and spleen, followed by rapid recovery of CFU-mast numbers. Expression of the SCF gene is one-fiftieth the level of that of TGF-ß during the steady-state in BM and spleen. After 5-FU treatment, SCF mRNA levels in the BM markedly increased, approaching TGF-ß mRNA levels, whereas SCF levels in the spleen showed limited oscillations whose increases paralleled those in TGF-ß levels. In contrast, LPS treatment induces a rapid decrease in CFU-mast number in the BM and a rapid increase in of CFU-mast number in the spleen. After LPS treatment, SCF mRNA levels in the BM markedly decreased, whereas SCF levels in the spleen remained unchanged. These results suggest that regulation of mast-cell-development is dominated by negative-signals in the BM and spleen during the steady-state, and, under biostress-conditions such as 5-FU and LPS treatment, the balance between positive- and negative-regulation can be changed in the BM but not in the spleen. The difference in the regulation of mast-cell-development in the BM versus the spleen probably reflects the different roles of tissue-specific stromal-cells.
