Post-incisional ventral hernia repair in patients undergoing chemotherapy: improving outcomes with biological mesh.

BACKGROUND: Patients requiring ventral hernia (VH) repair during perioperative chemotherapy have a higher risk for post-operative complications. The aim of the study was to perform a case-controlled analysis in patients undergoing chemotherapy who underwent VH repair using biological mesh or synthetic mesh. METHODS: From January 2013 to December 2015, 32 patients, within 8 weeks from chemotherapy administration, were treated electively for VH repair using a biological mesh (BIOMESH). A control group (CG) receiving chemotherapy within the same time interval and treated with synthetic meshes was selected. There were no differences regarding sex, age, American Society of Anesthesiologists (ASA) score III, BMI, and size of the defect. Morbidity, type of complications, and recurrence rate were investigated and compared between the two groups. RESULTS: In the BIOMESH group, eight patients (25 %) experienced complications. Wound dehiscence occurred in four (12.5 %) patients and was treated conservatively. Only three small seromas not requiring treatment were observed. The CG presented a higher mean Clavien-Dindo complication grade (1.94 ± 0.44 vs 1.63 ± 0.52; p = 0.13) and a higher incidence of wound dehiscence (n = 9/32, 28.1 % vs n = 4/32, 12.5 %; p = 0.11). Five patients developed seroma treated by wound drainage. One patient experienced an intra-abdominal collection treated by percutaneous drainage. At the univariate and multivariate analysis use of traditional mesh, BMI and the ASA III were predictive factors of post-operative complications. Two patients (6.3 %) developed a VH recurrence only in the CG. CONCLUSIONS: Biological meshes could be considered a valid option to improve post-operative short-term outcomes in selected high-risk patients undergoing chemotherapy treated for VH repair.

Locoregional IL-2 therapy in the treatment of colon cancer. Cell-induced lesions of a murine model.

BACKGROUND: Local therapy with IL-2 may be very effective in the treatment of different forms of cancer. The aim of this study was to determine the effectiveness of IL-2 locoregional application in the treatment of colon cancer. MATERIALS AND METHODS: Twenty eight syngenic BDIX rats were utilized in this study. The rats were divided into two groups of fourteen animals: group T (treatment) and group C (control). All rats of both groups were injected, under the splenic capsule, with T 10(7) DHD/K2/ TRb neoplastic cells. Then, within and around the site of the previous inoculation, the T group was injected with 1 ml of glucosate solutions + 0.1% albumin (BSA) containing 2.5 x 10(6) IU of IL-2 ( Proleukin-Chiron), whereas the C group was injected with 1 ml of BSA alone. After three weeks, rats were sacrificed and the liver and spleen were removed. The following parameters were considered: volume and weight, neoplastic-non neoplastic tissue index of the spleen, mitotic index and vascular density of splenic and hepatic lesions. RESULTS: All the studied parameters showed statistically significant differences in treated and untreated animals. CONCLUSION: This study of a murine model demonstrated that IL-2 locoregional therapy may be effective in the treatment of colon cancer.

[Hemorrhoidectomy with ropivacaine (Naropin) local anesthesia. Preliminary experience]. / L'emorroidectomia in anestesia locale con ropivacaina (Naropina). Esperienza preliminare.

BACKGROUND: The use of local anesthesia in non-septic anal surgery is now well established. Tolerance to local injection, duration of local effect and the risk of local or systemic complications still represent unsolved issues. Ropivacaine, a new local anesthetic, seems particularly indicated for this kind of surgery because of its pharmacologic properties which reduce patient's discomfort during infiltration and provide good antalgic coverage in the first hours following the operation. METHODS: The first 20 consecutive cases operated with local anesthesia by ropivacaine have been prospectively studied. All patients have been given an 11-point box VAS scale which is used for subjective evaluation of pain. RESULTS: Mean pain score resulted 1.1, 1.6 and 1.4 at 1, 2 and 3 postoperative hours, respectively. Thirty percent of patients subsequently required pain medication up to the first bowel movement. No complications related to the use of ropivacaine has been observed. CONCLUSIONS: This new drug can be safely used in the outpatient or Day-Surgery treatment of hemorrhoids.

[Surgical rehabilitation of stomal disease]. / La riabilitazione chirurgica delle patologie stomali.

The Authors report their experience in the surgical rehabilitation of patients with complicated ileo- or colostomy. Mechanical and psychosocial implications as well as different rehabilitative methods are discussed. The results of a surgical protocol in the treatment of stomal diseases observed in 63 patients are herein reported. In 14 patients the surgical treatment was performed in general anaesthesia, while in 49 local anaesthesia was used. The latter was better tolerated by the patients. In conclusion, surgery should play a major role in this rehabilitation protocol, either in terms of prevention or definitive treatment.

[Endolaparoscopic "Rendez-vous" in the treatment of cholecysto-choledochal calculosis]. / Il "Rendez-vous" endolaparoscopico nel trattamento della calcolosi colecisto-coledocica.

Different methods, all of which equally efficacious and safe, can be selected to access the choledochus in patients with cholecysto and choledocholithiasis on the basis of clinical and anatomosurgical parameters. From 1990 we evaluated three groups of patients who underwent surgery at different times and with different methods: sequentially (endoscopic sphincterotomy and laparoscopic cholecystectomy), one step laparoscopy and combined laparo-endoscopy. The results obtained seem to show that the treatment with laparoscopy alone is the most advantageous in terms of cost-benefit, while the endoscopic access of the choledochus during laparoscopic cholecystectomy is the one to prefer in terms of efficacy and safety.

[Gastric resection and subtotal gastrectomy. Principles and updated surgical technique]. / La resezione gastrica e la gastrectomia subtotale. Princìpi ed attualità di tecnica chirurgica.

The Authors describe their last 10 years experience in gastric surgery. They report the results obtained in 12 gastric resections performed for complications following gastric and/or duodenal peptic ulcers, in 33 cases of total gastrectomies (34%), and 48 cases of subtotal gastrectomies (49%) for early and advanced cancer. The results lead to interesting conclusions: first of all achieving a wide jejunojejunostomy between the afferent and the efferent loop the problems related to gastric resection (as postoperative sequelae, dumping syndrome, reflux esophagitis, alkaline gastritis, etc.) are avoided. Problems regarding lymphadenectomy in patients submitted to subtotal gastrectomy (D2-D3) are then reported. After a brief history of gastric reconstruction following gastric resection the evolution in surgical techniques and the results obtained during the last 10 years are described. The good long term results allow to conclude that our strategy in gastric surgery ensures a good quality of life of the patients as well as a radical operation in case of gastric cancer.

[Pain and pancreaticojejunostomy. Considerations on surgical anatomy and physiopathology]. / Dolore e pancreatico-digiunostomia. Considerazioni di anatomia chirurgica e fisiopatologia.

The Authors report the case of a patient who, following a side-to-side Wirsung-jejunostomy for chronic pancreatitis, became symptomatic again for anastomotic obstruction and progression of the pancreatic disease. Results of pancreaticojejunostomy are compared to those reported by other Authors. Controversies on pathophysiology, diagnosis, and therapy are analyzed as well.
