Laparoscopic technique in enlarged cystic duct.

The risk of dislodgment of endoclips placed during laparoscopic cholecystectomy in enlarged cystic duct is higher with minor bile leak. From January 2000 to April 2004, we performed 1013 procedures; in 12 patients we have showed a enlarged duct ligated with 4 laparoscopic cholecystectomy endoclips after a 180 degrees rotation of the gallbladder during a retrograde cholecystectomy. We haven't registered complications and all the cases were discharged the first postoperative day. The method is safe and economically sound.

[Longo hemorrhoidopexy vs Milligan-Morgan hemorrhoidectomy: perspective analysis].

The authors analyzed their experience from January 2001 to February 2005 on 117 patients treated with Longo hemorrhoidopexy (46 cases) and Milligan-Morgan hemorroidectomy (71 cases). All the patients were observed after a week and one month after surgical procedure; at 6 months the Authors controlled 70 patients treated with Milligan-Morgan and 33 treated with Longo technique. The pain after 24 hours was the same in two groups but after a week a significative difference between two groups (p<0.05) was registered with a better quality of life for hemorrhoidopexy group. At 6 months pain during defecation was present in two cases of Longo group and in 6 cases of Milligan-Morgan group. In author's experience the Longo technique is a safe treatment with lower postsurgical pain and lower complications.

Skeletal muscle and peripheral nerve changes caused by chronic arterial insufficiency--significance and clinical correlations--histological, histochemical and ultrastructural study.

A histological, histochemical and ultrastructural study on muscle changes in chronic arterial insufficiency has been carried out in 40 patients. Muscle biopsy probes were taken in each patient either from the gastrocnemius or rectus femoris. In 7 patients submitted for amputation of a lower limb due to a more severe vascular disease, specimens were also obtained from both the sciatic and sural nerve for light and electron microscopic study. Our findings confirm the previous histological, histochemical and ultrastructural data on chronic ischemia of the skeletal muscle, suggesting that muscle damage is mainly based on a neurogenic noxa initiated by an ischemic peripheral neuropathy. In addition, many morphologic features also show the presence of a primary myopathic noxa, possibly depending on the direct damage of the mitochondrial respiratory chain by the deficit of the muscle blood supply.

Symptomatic non-parasitic congenital cysts of the liver.

Seven cases of symptomatic non-parasitic congenital cysts of the liver are reported. Preoperative correct diagnosis can be established with non-invasive examinations, essentially with echotomography. Laparoscopy can represent a decisive investigation, permitting the direct view of the cysts. Surgical treatment of non-parasitic congenital cysts is based upon the excision of the lesions when symptomatic; this is the only definitive treatment.

[Aerobic bacterial flora in the bile (author's transl)].

Bacteriological investigation was carried out on bile samples obtained during surgery from patients with multiple diseases of the biliary tract. This study, aimed only at the aerobic biliary flora, showed that the highest incidence of gacteria in the bile was found in repeat surgery for post-operative stenosis of the hepatic bile duct; second in order was lithiasis of the common bile duct. The antibiogram results on the bacterial species isolated are reported.

Major acute inflammatory complications of diverticular disease of the colon: planning of surgical management.

BACKGROUND/AIMS: The aim of this study was to determine the most appropriate surgical strategy in the management of patients with major inflammatory complications of colonic diverticular disease. MATERIALS AND METHODS: Out of 259 patients affected by complicated diverticular disease of the colon, 43 consecutive patients (16.6%) who underwent urgent or emergency surgical intervention for diverticular perforation during a 20-year period (1975-1994) were retrospectively analyzed. According to the changes in the surgical approach over the time, the series was divided into two groups: 1975-1985 group A (n = 23), 1986-1994 group B (n = 20). The clinical diagnosis was confirmed by operative and pathologic findings. RESULTS: Out of 43 patients, 11 underwent derivative procedure and 32 resection. There were no significant differences among the two groups of patients according to sex ratio and mean age. The overall percentage of patients in group B who underwent resective procedure (100%) was significantly greater in comparison with that in group A (52%) (p < 0.001). Colostomy and drainage was employed only during the first period (30%)(vs group B, p < 0.05) and the proportion of patients who underwent primary resection and anastomosis was significantly higher during the second period (45%) (vs group A, p < 0.05). CONCLUSIONS: It must be stressed that resection of the diseased segment at initial operation appears mandatory; one-stage procedure is indicated when infection is confined to the mesentery, while resection and anastomosis with covering colostomy (two-stage procedure) is preferable whenever peritoneal contamination has occurred. Hartmann's operation remains the procedure of choice in the patients presenting known impaired immunity or fecal contamination.

From Bassini to tension-free mesh hernia repair. Review of 1409 consecutive cases.

The short and long-term results of traditional and tension-free inguinal hernia repairs have been assessed in three surgical units. In order to standardise the results, hernias were classified according with Nyhus. There were 109 type I, 311 type II, 854 type III, and 125 type IV hernias. Follow-up was possible in 1201 patients (1249 hernia repairs). Postoperative course, postoperative pain, and recurrences were analysed. Recurrences ranged from 0.7% up to 9.3%. The tension-free methods of repair provided the most important advantages in term of low recurrence rate and early return to work even if, in our series, recurrences resulted mainly related to the type of hernia than to the type of repair. The Authors conclude that any hernia repair should be sized to the type of hernia defect in order to avoid over-treatment and abusive placing of a foreign body such as polypropylene mesh.
