RESUMEN
PURPOSE: To investigate pain and other complications following inguinal hernioplasty performed by the Lichtenstein technique with mesh fixation by fibrin glue or sutures. METHODS: Five hundred and twenty patients were enrolled in this 12-month observational multicenter study and received either sutures or fibrin glue (Tissucol(®)/Tisseel(®)) based on the preference of the surgeon. Pain, numbness, discomfort, recurrence, and other complications were assessed postoperatively and at 1, 3, 6, and 12 months. Pain intensity was assessed by a visual analog scale (VAS; 0 [no pain] to 10 [worst pain]). RESULTS: One hundred and seventy-one patients received sutures and 349 received fibrin glue. During the early postoperative phase, 87.4% of patients in the fibrin glue group and 76.6% of patients in the sutures group were complication-free (P = 0.001). Patients who received fibrin glue were also less likely to experience hematoma/ecchymosis than those in the suture group (both P = 0.001). The mean pain score was significantly lower in the fibrin group than the sutures group (2.5 vs. 3.2, P < 0.001). At 1 month, significantly fewer patients in the fibrin glue group reported pain, numbness, and discomfort compared with patients in the sutures group (all P < 0.05). Fibrin glue patients also experienced less intense pain (0.6 vs. 1.2; P = 0.001). By 3 months, the between-group differences had disappeared, except for numbness, which was more prevalent in the sutures group. By 12 months, very few patients reported complications. CONCLUSIONS: Tissucol fibrin glue for mesh fixation in the Lichtenstein repair of inguinal hernia shows advantages over sutures, including lower incidence of complications such as pain, numbness, and discomfort, and should be considered as a first-line option for mesh fixation in hernioplasty.

The peritoneal inclusion cyst is a rare, probably congenital, pathology of the mesothelium that develops on coelomatic residues. A case is reported of an unusual location of peritoneal cyst, in which the increase in volume, associated with the patient's concern and the presumed anatomic site of the lesion led to its removal by the laparoscopic route. The type of location and the relative inaccuracy of preoperative imaging are discussed.

AIM: The aim of the work was to study in colon-rectum cancer mucosae the binding charateristics, as sex steroid receptors. METHODS: Specific androgen (AR), estrogen (ER) and progesterone (PgR) receptors were measured in the tissue samples of 35 patients (15 males, 20 females) undergoing colectomy or coloproctectomy for adenocarcinoma. The characteristics of androgen receptor (AR, DHT-R: dihydrotestosterone receptor) were also investigated using competitive activity of cyproterone acetate, cortisol, aldosterone and steroid-like substances such as deoxycholic and lithocholic acid, present in the milieu of the considered organ. Binding assays and competition tests were conducted using a charcoal dextran method. RESULTS: When present (50%), ER and PgR receptors showed very low levels and no difference was noted between cancerous and the surrounding healthy mucosa. AR were found in all samples from both neoplastic and non neoplastic surrounding mucosa, with no significant difference. Androgen receptor however exhibited an altered binding activity in cancer specimens. Cyproterone acetate did not displace DHT from AR while significant displacing activity was elicited by DHT, testosterone, as well as by lithocholic acid, but not by deoxycholic acid. CONCLUSION: In cancerous large bowel mucosa, androgen receptors show altered binding characteristics. The selective binding of lithocholic acid to AR supports the hypothesis that diet-related endoluminal substances may play a role in cancer development model where molecular alterations such as DNA damage or mutation is the 1st event.
