Abstract

The peritoneum exists as a closed sac within a second closed sac, the fascial layer derived from and continuous with transversalis fascia. Extraperitoneal abscess may occur between the peritoneum and the deep fascia anteriorly, posteriorly, or in the pelvis. Extrafascial abscess is a form of extraperitoneal abscess that develops outside the transversalis layer and may occur anteriorly a well as posteriorly. A classification of extraperitoneal infection is proposed, which is both clinically applicable yet reflects the anatomic relationship of the peritoneum and transversalis fascia.

IL-10 is a major mediator of sepsis-induced impairment in lung antibacterial host defense.

To explore the mechanism of immunosuppression associated with sepsis, we developed a murine model of sepsis-induced Pseudomonas aeruginosa pneumonia. CD-1 mice underwent either cecal ligation and 26-gauge needle puncture (CLP) or sham surgery, followed by the intratracheal (i.t.) administration of P. aeruginosa or saline. Survival in mice undergoing CLP followed 24 h later by the i.t. administration of saline or P. aeruginosa was 58% and 10%, respectively, whereas 95% of animals undergoing sham surgery followed by P. aeruginosa administration survived. Increased mortality in the CLP/P. aeruginosa group was attributable to markedly impaired lung bacterial clearance and the early development of P. aeruginosa bacteremia. The i.t. administration of bacteria to CLP-, but not sham-, operated mice resulted in an impressive intrapulmonary accumulation of neutrophils. Furthermore, P. aeruginosa challenge in septic mice resulted in a relative shift toward enhanced lung IL-10 production concomitant with a trend toward decreased IL-12. The i.p., but not i.t., administration of IL-10 Abs given just before P. aeruginosa challenge in septic mice significantly improved both survival and clearance of bacteria from the lungs of septic animals administered P. aeruginosa. Finally, alveolar macrophages isolated from animals undergoing CLP displayed a marked impairment in the ability to ingest and kill P. aeruginosa ex vivo, and this defect was partially reversed by the in vivo neutralization of IL-10. Collectively, these observations indicate that the septic response substantially impairs lung innate immunity to P. aeruginosa, and this effect is mediated primarily by endogenously produced IL-10.

Adhesion formation is reduced after laparoscopic surgery.

BACKGROUND: Adhesion formation after abdominal operations causes significant morbidity. METHODS: Adhesion formation in pigs was compared after placement of prosthetic mesh during celiotomy (group 1), laparoscopy with large incision (group 2), and laparoscopy (group 3). After peritoneum was excised, polypropylene mesh was fixed to the abdominal wall, then to the opposite abdominal wall in the preperitoneal space followed by peritoneal closure. Adhesion area, grade, and vascularity were measured. RESULTS: More adhesions (p < 0.02) covered intraperitoneal mesh (7.57 +/- 1.89 cm2) than covered reperitonealized mesh (2.16 +/- 1.13 cm2), and adhesion grade was significantly greater (p < 0.02). Adhesion areas were significantly greater in groups 1 and 2 than in group 3 (p = 0.001 and 0.03, respectively). Adhesion grade was significantly greater in groups 1 and 2 than in group 3 (p = 0.02 and p = 0.04, respectively). Groups 1 and 2 had more vascular adhesions than group 3 (p < 0.01 and p = 0.02, respectively) CONCLUSIONS: A foreign body within the peritoneum stimulates more numerous and denser adhesions. Tissue trauma distant from the site of adhesions increases their formation. A major advantage of laparoscopic surgery is decreased adhesion formation.

Abdominal, laparoscopic, and vaginal hysterectomy with bilateral salpingo-oophorectomy: a feasibility study for further evaluation in randomized trials.

BACKGROUND: The abdominal route is the traditional method of performing hysterectomy with bilateral salpingo-oophorectomy. In a feasibility study, we compared a nonconventional (vaginal) route for bilateral salpingo-oophorectomy at the time of vaginal hysterectomy (VH + BSO) to similar forms of hysterectomy performed abdominally or with operative laparoscopy. METHODS: Fifty-nine patients were subject to either total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH + BSO; n = 19), or laparoscopic-assisted vaginal hysterectomy and bilateral salpingo-oophorectomy (LAVH + BSO; n = 19) or VH + BSO (n = 21). RESULTS: VH + BSO resulted in a shorter operating time compared to LAVH + BSO (p < 0.001), shorter hospital stay compared with TAH + BSO (p = 0.001), and quicker long-term recovery compared to the other two operations. CONCLUSION: This preliminary but significant study shows that the vaginal route for salpingo-oophorectomy at the time of vaginal hysterectomy is superior to other methods of hysterectomy. A randomized trial is needed to confirm these initial findings.
