Giant condyloma acuminata, first described by Buschke and Löwenstein in 1925 as a penile lesion, is extremely rare in the anorectal region. The cauliflower-like tumor behaves clinically in a malignant fashion, although it shows no histomorphological criteria of malignancy. Up to the time of writing only 33 cases of anorectal origin, 42% with malignant transformation, have been published. The authors report 2 more cases of squamous-cell carcinoma in giant anorectal condylomata acuminata. Buschke-Löwenstein tumor is an intermediate entity between "ordinary" condyloma acuminata and squamous-cell carcinoma. Benign condyloma acuminata is caused by human papillomavirus 6 or 11. Carcinogenic cofactors promote the transition to giant, locally destructive condyloma acuminata and subsequent malignant transformation. Cure can only be achieved by early and radical excision. Formation of multiple fistulas and destruction of the sphincter may necessitate abdomino-perineal resection. Adjuvant radiation therapy should only be considered to render a tumor operable, as radiation may act as a cocarcinogenic effect and lead to a less differentiated and more aggressive cancer. The small number of cases reported and the variety of treatment regimens applied, however, do not allow the formulation of definitive therapeutic guidelines.

This study set out to compare adhesion reformation after conventional and laparoscopic adhesiolysis using two different laparoscopic dissection techniques. In a first operation, 36 rabbits underwent fixation of 6 cm2 of the cecum with the serosa removed to the lateral abdominal wall to induce standardized adhesions. After 4 weeks, adhesiolysis was performed laparoscopically (n = 12) or via laparotomy (n = 12) using sharp and blunt dissection. In a third group (n = 12), laparoscopic adhesiolysis was performed using monopolar electrocautery. Outcome was assessed by incidence, extent, and localization of adhesion reformation. After conventional adhesiolysis, all rabbits developed new adhesions relative to 79% after laparoscopic adhesiolysis. The extent of reformed adhesions (median) was greater after conventional adhesiolysis than laparoscopic adhesiolysis (2725 mm2 vs 230 mm2, P < 0.001). The latter did not differ significantly from laparoscopic adhesiolysis by electrocautery (310 mm2). There were small adhesions to 3 of 72 trocar wounds, but extensive adhesions to 33% of the abdominal incisions were found in the conventional group. In this standardized experimental setting, laparoscopic adhesiolysis is associated with a significantly reduced reformation of adhesions. Different laparoscopic dissection techniques have no significant influence on the extent of adhesion reformation.

Phospholipids and icodextrin were effective in preventing re-formation of adhesions.

This study aimed to compare new adhesion formation after laparoscopic and conventional adhesiolysis. In a first operation, 24 rabbits underwent fixation of deserosated cecum (6 cm2) to the lateral abdominal wall to induce standardized adhesions. After 4 weeks, adhesiolysis was performed by laparoscopy (n = 12) or laparotomy (n = 12). Outcome was assessed by the incidence, extent, and location of adhesion reformation. After conventional adhesiolysis, new adhesions developed in all the rabbits, as compared with 75% after laparoscopic adhesiolysis. The extent of newly formed adhesions was significantly reduced (p < 0.001) after laparoscopic adhesiolysis (368+/-115 mm2) as compared with conventional adhesiolysis (2434+/-245 mm2). There were no adhesions to trocar wounds, but adhesions to the abdominal incision were found in 33% of the conventional group. In a rabbit model comparing laparoscopic and conventional adhesiolysis in a standardized experimental setting, laparoscopic adhesiolysis is associated with a significantly reduced formation of new postoperative adhesions.

The objective of this study was to analyze the etiologic factors possibly associated with the development of recurrent groin hernias in infants and children. For this purpose we analyzed the records of 2754 pediatric patients operated on for primary hernias between 1966 and 1990 at our department who have not had recurrences. They were compared with 28 boys and 4 girls we treated for recurrent hernias during the same period. We found an indirect hernia in 29 cases, a direct hernia in 4 patients, and a femoral hernia in 1 child at the time of reoperation. A significantly high recurrence rate was found to be associated with incarceration (21.9% versus 7.6%), postoperative complications (9.4% versus 1.8%), concomitant diseases (31.2% versus 5.7%), and premature birth. Day case treatment was closely related to concomitant diseases. No impact on the development of recurrences was seen for the surgeons' educational level and the time of day the surgery was performed. Knowledge of the factors contributing to hernia recurrence and perfect surgical technique with reduction of incarcerated hernias and early elective operation may result in fewer recurrences in infants and children.
