Paradoxical inflammatory reaction to Seprafilm: case report and review of the literature.
Abstract: This report describes a paradoxical inflammatory reaction to Seprafilm caused by extensive adhesion formation early in the postoperative period. A female patient had development of small bowel obstruction immediately after an uneventful low anterior resection for rectal carcinoma with placement of Seprafilm. The obstruction did not improve with nonoperative therapy. At laparotomy laparotomy /lap·a·rot·o·my/ (-rot´ah-me) incision through the flank or, more generally, through any part of the abdominal wall.

The information provided by this and other atypical reports suggests that further studies aimed at identifying the incidence and pathophysiological mechanisms for such paradoxical reactions are needed.
Key Words: Seprafilm, paradoxical adhesion, bowel obstruction, peritonitis peritonitis (pĕr'ĭtənī`tĭs), acute or chronic inflammation of the peritoneum, the membrane that lines the abdominal cavity and surrounds the internal organs.
It is estimated that postoperative adhesions occur in 67 to 93% of patients undergoing abdominal or pelvic surgery. (1,2) Such adhesions can lead to complications including small bowel obstruction (49 to 74%), infertility (15 to 20%), and chronic pelvic pain Women and Pelvic pain
Most women (and some men), at some time in their lives, experience pelvic pain. When the condition persists for longer than 3 months, it is called chronic pelvic pain (CPP). (20 to 50%). (3,4) Although the pathophysiology of adhesion formation is not completely understood, numerous surgical adjuncts have been introduced in recent years to decrease the incidence and clinical implication of adhesions. One such method involves the use of a bioabsorbable adhesion barrier composed of sodium hyaluronate hyaluronate /hy·al·uro·nate/ (hi?ah-ldbobr´ro-nat) a salt, anion, or ester of hyaluronic acid. The sodium salt and a derivative of it are used as analgesics in the treatment of osteoarthritis of the knee. and carboxymethylcellulose carboxymethylcellulose /car·boxy·meth·yl·cel·lu·lose/ (-meth?il-sel´u-los) a substituted cellulose polymer of variable size, used as the sodium or calcium salt as a pharmaceutical suspending agent, tablet excipient, and (Seprafilm, Genzyme Corp, Cambridge, MA).

(5-7) We report a case of extensive inflammatory reaction in a patient in whom Seprafilm was used during an uncomplicated low anterior resection. An extensive literature search yielded only two other case reports of paradoxical adverse reactions to this adhesion barrier. (8,9)

At surgery, the scant adhesions from the prior surgeries were lysed and the low anterior resection proceeded uneventfully.

At laparotomy, she was found to have extensive, dense adhesions involving the abdominal wall, omentum, and multiple loops of small bowel. There were several sites of obstruction with proximal dilation within this mass of adhesed loops. These loops were fused together in several sites, which prevented separation. The adhesions were lysed; however, four enterotomies were created, necessitating an ileocecectomy with a partial omentectomy and ileostomy. The previously created colorectal anastomosis appeared to be intact. However, two loops of ileum ileum: see intestine.

The pathology showed diffuse inflammation with multiple giant cells suggesting a foreign body reaction (Figs. 1 and 2). The patient recovered well and was ultimately transferred to a rehabilitation facility. She was doing well at her 6-week visit.
Postoperative adhesions form after most intraperitoneal procedures. Sixty-seven percent of patients undergoing laparotomy have development of adhesions, according to autopsy studies conducted by Weibel and Majno. (1) After multiple operations, this incidence rises to 93%, as demonstrated in the prospective clinical trial performed by Menzies and Ellis. (2) Such adhesions can cause numerous complications, costing substantial healthcare dollars. According to the National Inpatient Profile, more than 400,000 laparotomies were performed for lysis of adhesions in 1993 in the United States.
The precise cause of adhesion formation is not completely understood, although numerous methods have been used to prevent this complication, including mechanical barriers. Seprafilm is composed of two anionic polysaccharides, sodium hyaluronate and carboxymethylcellulose, which have been chemically modified. This barrier transforms into a gel after being placed in the peritoneum peritoneum (pĕrətənē`əm), multilayered membrane which lines the abdominal cavity, and supports and covers the organs within it. The part of the membrane that lines the abdominal cavity is called the parietal peritoneum. and is reabsorbed in approximately 7 days, after normal tissue repair has taken place and the inflammatory cascade has subsided. It thus prevents adhesions by physically separating raw surfaces temporarily.

However, the degree to which anastomotic leak contributed to their findings was not clear. An extensive review of the literature for adverse reactions to Seprafilm yielded only two other case studies. Klinger et al (9) published a report on Seprafilm-induced peritoneal inflammation in a patient who had undergone completion proctocolectomy. This patient had a fever and partial small bowel obstruction on postoperative day 4. (10,11) On exploratory laparotomy, an area of intense inflammation corresponding to the site of Seprafilm placement was observed. Histologic examination revealed a foreign body granulomatous granulomatous /gran·u·lom·a·tous/ (-lom´ah-tus) containing granulomas.

The high incidence of postoperative adhesion formation and the morbidity associated with its complications warrant the use of adjuncts such as mechanical barriers. Seprafilm is clinically proven to be safe and effective in preventing adhesion formation. Rarely, however, this substance may cause an intense inflammatory response that resembles peritonitis or may cause a bowel obstruction. Because these findings are uncommon, increased reporting will better clarify the incidence and help identify the cause of such paradoxical reactions.

* Seprafilm has been proven to be a safe and effective adhesion barrier after abdominopelvic surgery.
* Rare adverse inflammatory reactions to Seprafilm indicate that certain predisposing factors might exist that contribute to this phenomenon.
* Given the widespread use of adhesion barriers in abdominopelvic surgical procedures, further experimental studies are warranted for investigating the underlying pathophysiological mechanisms for these aberrant inflammatory reactions.
