A prospective study of erectile dysfunction in men after pelvic surgical procedures and its association with non-modifiable risk factors.

OBJECTIVE: A pelvic surgery can cause erectile dysfunction. The purpose of this study was to evaluate erectile function at various times after pelvic surgery in male patients; to search the non-modifiable risk factors associated with the presence and intensity of sexuality in these patients. This prospective study used the erectile dysfunction IIEF scale. RESULTS: The study population comprised of 106 male patients who had undergone minor pelvic surgery at least 9 months before and during the 2010-2016 period in the 4th Surgical Clinic. A control group of healthy males (N = 106) who underwent no pelvic surgery matched for age was also used for reference values. The main age of the participants was 66.16 ± 13.07 years old. A history of colectomy was present in 36.8%, 18.9% had undergone sigmoidectomy, and 33% inguinal hernia repair. The percentage of severe erectile function increased from 38.7% before surgery to 48.1% (25% increase) after surgery, at the end of the follow-up period (p < 0.05). In the multivariate analysis model, age emerged as an independent predictor of erectile function (p < 0.001). Age was the most important determinant of the IIEF score, which was aggravated by 25% from the first to the last assessment of patients.

Iatrogenic liver trauma managed with mesh-wrapping and ligation of portal vein branch: A case report.

INTRODUCTION: Liver trauma is a critical condition that requires swift multidisciplinary approach. In complex hepatic injuries perihepatic packing is an established life-saving procedure. The aim of this study is to evaluate and highlight the value of absorbable mesh wrapping of the injured liver, combined with ipsilateral ligation of portal vein branch. CASE PRESENTATION: An 82-year-old patient underwent an open cholocystectomy, for gallbladder empyema. The second postoperative day he was re-operated on due to active hemorrhage. The bleeding was controlled by suturing the bed of the gallbladder fossa. During this maneuver a portal vein branch was torn resulting in a rapidly expanding subcapsular liver hematoma which led to the formation of two deep lacerations on the liver parenchyma. This life-threatening condition was treated by wrapping an absorbable mesh around the right liver lobe and subsequently ligating the right portal vein branch extrahepaticaly. CONCLUSION: Mesh wrapping of the fragmented liver with absorbable mesh constitutes a safe and effective method, in treating grade IV and V liver injuries, especially when combined with ipsilateral ligation of the bleeding vessel.

Effect of collagen powder on lymphorrhea after modified radical mastectomy. A randomized controlled trial.

AIM: Postoperative lymphorrhea is a major complication of axillary lymphadenectomy. The aim of our study was to evaluate the impact of type I collagen in postoperative lymphorrhea in mastectomy patients. METHODS: Eighty patients that underwent modified radical mastectomy for breast cancer were randomized in two groups. In group A (collagen group, n = 42) collagen type I (Cellerate RX powder) was applied in the axillary cavity after lymphadenectomy while in group B (control group, n = 38) lymphadenectomy was performed in the standard fashion without the use of a sealant. Suction drains remained in place until the daily amount of lymphatic drainage fell under 30 ml. The total amount and the duration of drainage, as well as the morbidity and severity of arm pain were compared in the two groups. RESULTS: There was a non significant trend towards lower overall drainage in the collagen group. The duration of drainage and postoperative pain were similar in the two groups, as was morbidity. Subgroup analysis of patients according to the number of lymph nodes excised, revealed significantly less lymphorrhea in terms of volume and duration in patients who had more than ten lymph nodes excised. CONCLUSION: Collagen type I (Cellerate RX powder) appears to attenuate postoperative lymphorrhea in patients undergoing axillary lymphadenectomy especially when > 10 lymph nodes are removed.

Results of salvage abdominoperineal resection after failed chemoradiation therapy for epidermoid anal canal carcinoma: Retrospective analysis at a single institution.

PURPOSE: The standard therapeutic approach to epidermoid anal canal cancer consists of combined radiation therapy and chemotherapy. Although disease control has been reported to have excellent results, as many as 40% of patients will develop locoregional disease progression. The treatment of choice for patients with persistent (PD) or recurrent disease (RD) is salvage abdominoperineal resection (APR). The purpose of this study was to review our experience with salvage surgery in this group of patients. METHODS: The medical records of all patients with epidermoid anal canal cancer treated from 1997 to 2010 in our department were retrospectively reviewed. Nine patients who presented with persistent or locally recurrent anal canal cancer were subjected to salvage APR. Before surgery, all of the patients had received chemoradiation therapy (CRT). RESULTS: There were 9 patients (7 women, 2 men) with a median age of 59 years (range 40-79). Six patients underwent radical salvage APR for persistent disease and 3 patients for recurrent disease. There were no deaths attributable to operation. The median follow-up time was 31.75 months (range 3-108) after salvage surgery. Two patients died of disease progression, with a median survival time of 24 months (range 12-36). At the time of last follow-up, 6 patients were alive without evidence of recurrent disease, and one patient was lost to follow-up. The median follow-up time for survivors was 34.3 months (range 3-108). CONCLUSION: Long-term survival can be achieved in the majority of patients who undergo radical salvage APR after failed CRT for epidermoid carcinoma of the anal canal.

A novel technique for surgical reconstruction of the perineal floor following anteroposterior exenteration of the pelvis--case report and review of the literature.

Pelvic exenteration is the only potentially curative surgical procedure for patients with recurrent cervical, vaginal, vulvar or rectal cancers, especially following adjuvant chemotherapy or radiotherapy. Morbidity rates, however, remain high, which is significantly attributed to complications of the pelvic floor reconstruction techniques. We describe a novel reconstruction technique of the pelvic floor, involving a combination of an oblique rectus abdominis myocutaneous flap and a synthetic absorbable mesh as a pelvic sling for additional support, in a 63-year-old female patient with recurrent vulvar carcinoma. Combining the use of myocutaneous flaps and prosthetic mesh material can provide an effective alternative solution to the complications arising from pelvic floor reconstruction of large defects after exenteration procedures, especially in previously irradiated settings. Further studies are necessary to define the long-term outcomes and indications of these techniques, as well as the optimal combination between the available myocutaneous flaps and prosthetic materials.

Desferrioxamine attenuates minor lung injury following surgical acute liver failure.

Acute liver failure (ALF) can be complicated by lung dysfunction. The aim of this study was to test the hypothesis that inhibition of oxidative stress through iron chelation with desferrioxamine (DFX) attenuates pulmonary injury caused by ALF. 14 adult female domestic pigs were subjected to surgical devascularisation of the liver and were randomised to a study group (DFX group, n = 7), which received post-operative intravenous infusion of DFX (14.5 mg x kg(-1) x h(-1) for the first 6 h post-operatively and 2.4 mg x kg(-1) x h(-1) until completion of 24 h), and a control group (n = 7). Post-operative lung damage was evaluated by histological and bronchoalveolar lavage fluid (BALF) analysis. DFX resulted in reduced BALF protein levels and tissue phospholipase (PL)A(2) activity. Plasma malondialdehyde and BALF nitrate and nitrite concentrations were lower, while catalase activity in the lung was higher after DFX treatment. PLA(2), platelet-activating factor acetylhydrolase and total cell counts in BALF did not differ between groups. Histological examination revealed reduced alveolar collapse, pneumonocyte necrosis and total lung injury in the DFX-treated animals. DFX reduced systemic and pulmonary oxidative stress during ALF. The limited activity of PLA(2) and the attenuation of pneumonocyte necrosis could represent beneficial mechanisms by which DFX improves alveolar-capillary membrane permeability and prevents alveolar space collapse.

Extraovarian peritoneal serous papillary carcinoma mimicking colonic obstruction.

Involvement of the colon by extraovarian peritoneal serous papillary carcinoma (EPSPC) is considered as rare. During a 10-year period the records of five female patients with a mean age of 73.4 years who were admitted for colonic obstruction due to EPSPC were reviewed. Preoperative and postoperative data were studied. All patients presented with symptoms of colonic obstruction and high concentrations of CA-125. Involvement of the sigmoid colon was demonstrated preoperatively both in CT and colonoscopy. Operative findings of multiple peritoneal implantations involving the surface of the ovaries in two cases, the greater omentum in three cases and invasion of the sigmoid colon in all cases prompted us to perform sigmoidectomy and omentectomy in all cases with bilateral salpingo-oophorectomy in four of them. All patients received adjuvant paclitaxel plus platinum-based combination chemotherapy.

Role of lipid emulsion administration in acute lung injury during liver transplant rejection: a case report.

We report the case of a 58-year-old woman who developed rejection and acute lung injury 10 days after an orthotopic liver transplantation while receiving total parenteral nutrition. Examination of bronchoalveolar lavage fluid revealed large lipid droplets in the alveolar macrophages. Intensification of the immunosuppressive therapy attenuated the liver allograft rejection followed by resolution of lung injury.

Effect of the portacaval shunt on reperfusion injury after 65% hepatectomy in pigs.

BACKGROUND: Portal flow diversion by portacaval shunts (PCS) has been shown to prevent primary graft nonfunction in liver transplantation using small-for-size grafts. In this study, we examine whether PCS can improve reperfusion injury after major hepatectomy in pigs. MATERIALS AND METHODS: In 14 pigs, a partial PCS was constructed following 65% hepatectomy and 1 h of inflow ischemia. During 24 h of reperfusion, the shunt was either closed (group A, n = 7) or left open (group B, n = 7). RESULTS: 24 h after reperfusion, group A had higher levels of alanine aminotransferase (70 +/- 12 IU/l vs. 51 +/- 5.9 IU/l; p < 0.05), alanine aminotransferase per gram of liver remnant (0.41 +/- 0.07 IU/l/g vs. 0.21 +/- 0.05 IU/l/g; p < 0.05), prothrombin time (24.1 +/- 2.4 s vs. 14.3 +/- 2.9 s; p < 0.05), international normalized ratio (2.11 +/- 0.15 vs. 1.29 +/- 0.28; p < 0.05), hepatocyte necrosis scores and percentages of nuclei stained for proliferating cell nuclear antigen (52.57 +/- 8.9% vs. 36.71 +/- 6%; p < 0.05) compared to group B. CONCLUSIONS: Partial portal flow diversion appears to attenuate reperfusion injury in a porcine model of major hepatectomy.

A malignant eccrine poroma in a pregnant woman: case report and review of the literature.

Malignant eccrine poroma is a rare cutaneous neoplasm that originates from the intraepidermal portion of the eccrine gland. It affects mainly elderly people while its occurrence in younger adults is extremely rare. We present the first reported case of a malignant eccrine poroma in a pregnant woman, with emphasis on its pathologic and immunohistochemical features. Early diagnosis and treatment of eccrine neoplasms are of crucial importance when pregnancy coexists, because of their tendency to aggravate under the influence of gestation-related changes.
