Laparoscopic transversus abdominis plane block is useful in pain relief after laparoscopic stapled repair of diastasis recti and ventral hernia.

Background: There is still no consensus on perioperative pain control techniques in patients undergoing laparoscopic surgery; protocols of conventional therapy can be improved by the use of perioperative anaesthesiologic techniques, such as epidural or loco-regional analgesic administration as transversus abdominis plane (TAP) block. The aim of this evaluation was to investigate the role of laparoscopic-assisted TAP block during repair of diastasis recti associated with primary midline hernias in term of post-operative pain relief. Methods: This was a retrospective evaluation of a prospectively maintained database including patients undergoing laparoscopic repair of diastasis recti associated with primary ventral hernia. Patients were divided into two groups: Group A patients (n = 34) received laparoscopic-assisted bilateral TAP-block of 7.5 mg/ml ropivacaine for each side and Group B patients (n = 29) received conventional post-operative therapy. All patients received 24 h infusion of 20 mg morphine; pain was checked at 6, 24 and 48 h after surgery by numeric rating scale (NRS) score. A rescue analgesia by was given if NRS score was >4 or on patient request. Results: No differences in operative time, complications and post-operative stay, no complications related to TAP-block technique were found. Post-operative pain scores (determined by NRS) were found to be significantly different between groups. Group A patients showed a significant reduction in NRS score at 6, 24 and 48 h (P < 0.005) and in the number of patients requiring further analgesic drugs administration (P < 0.005) compared to Group B patients. Conclusions: Laparoscopic-guided TAP-block can be considered safe and effective in the management of post-operative pain and in the reduction of analgesic need in patients undergoing laparoscopic repair of diastasis recti and ventral hernias. The non-randomised nature of the study and the lack of a consistent series of patients require further evaluations.

Cystic adrenal lesions: clinical and surgical management. The experience of a referral centre.

BACKGROUND: Cystic adrenal lesions (CALs) represent a rare entity having heterogeneity in etiology and clinical manifestations. Due to their very low incidence and heterogeneity in clinical aspects, many controversials still exist about their management. METHODS: From 1984 to 2012, 21 patients (7 M, 14 F, mean age 48.2 years) underwent adrenalectomy for CALs. 9 patients suffered from hypertension, and 7 were affected by thyroid disorders. RESULTS: 4 patients presented with vague abdominal pain, while in 17 patients the CAL was incidentally identified during imaging examinations. All patients underwent evaluation of adrenal functionality and imaging study. We found 1 case of cystic pheochromocytoma (confirmed by urinary and blood sampling, and MIBG-scan). All patients underwent adrenalectomy (open approach in the first 10 patients treated from 1984 to 1996, laparoscopic lateral transabdominal approach in the other 11 cases). Indication to surgery included: size over 4.5 cm in 16 cases, suspected malignancy at imaging evaluation (not confirmed by histology) in 4 cases, cystic pheochromocytoma in 1 case. Histology revealed 11 endothelial cysts, 3 pseudocysts, 6 epithelial cysts and 1 cystic pheochromocytoma. CONCLUSIONS: The presence of CAL, even asymptomatic, requires complete endocrinological evaluation and imaging study. In the presence of large size, endocrine activity or any suspicion of malignancy, patients must be referred to surgery.

Recurrence of paratesticular liposarcoma: a case report and review of the literature.

Paratesticular liposarcomas are rare tumors that typically affect adult. Diagnosis is very difficult and inadequate surgical excision leads to a high rate of recurrence.We report a case of local recurrence of paratesticular liposarcoma diagnosed six months following surgery.Since there is low response to adjuvant treatments, extensive surgery remains the only curative approach, as shown by the case described here and the following review of the literature.

Surgical treatment of pheochromocytoma in MEN 2.

Multiple endocrine neoplasia type 2 (MEN 2) is a rare autosomal dominant cancer syndrome. Forty to fifty percent of patients with MEN 2A develops pheochromocytoma. Surgeons treating these patients with pheochromocytoma have always been faced with question of whether to perform mono-or bilateral adrenalectomy and the timing of surgical intervention. Over the past 20 years, thanks to the development of ever more sophisticated techniques of diagnostic imaging (TC, MRI, Scintigraphy, PET), which make it possible to identify small lesions, and to ever more rapid laboratory tests, there has been a change in the surgical management of this condition. Surgeons moved from bilateral open adrenalectomy (6- 9) to laparoscopic partial adrenalectomy and cortical sparing (10-13). After partial adrenalectomy one third of the patients require replacement therapy because the function of the residual parenchyma was compromised by excessive devascularization during surgery. In patients with bilateral pheochromocytoma it is advisable to perform only partial adrenalectomy of at least one gland, i.e. to completely remove the gland with the larger lesion and remove part of the gland with the smaller lesion to reduce the risk of recurrence. The authors report 4 cases of MEN 2, including 2 first-degree relatives, which illustrate the progress made in surgical treatment for pheochromocytoma.

A rare case of malignant epithelioid angiomyolipoma in multiple locations: multifocal disease or metastases?

BACKGROUND: Perivascular epithelioid cell tumors (PEComas), make up a family of extremely rare mesenchymal neoplasms, with characteristic morphological, immunohistochemical and molecular findings. Malignant PEComas and gastrointestinal epithelioid angiomyolipoma (E-AML) are especially rare. To the best of our knowledge E-AML have not been found in the breast. The difficulty in determining what constitutes optimal therapy for PEComas, owing to the sparse literature available, led us to report this rare case. METHODS: We report a case of a 44-year-old woman, with a family history of multiple endocrine neoplasia syndrome (MEN) (gastrinoma, medullary thyroid cancer and parathyroid hyperplasia), affected by PEComa located in the kidney, stomach, ileum, liver and breast. RESULTS: The renal, gastric, ileal and mammarian tumors were completely resected, with no evidence of local disease. Liver lesions were biopsied. The morphological and immunohistochemical findings confirm the diagnosis of PEComa. CONCLUSION: On this basis it is difficult to determine if some E-AML are multifocal tumors or metastatic disease.
