This retrospective case series evaluated postoperative peritoneal effects on three patients undergoing laparoscopic endometriosis surgery who received a potato starch-based anti-adhesive agent, with assessment at second-look laparoscopy using medical, surgical, and histopathologic data. All patients developed de-novo intraperitoneal adhesions, and pathology showed noncaseating granulomatous inflammation of the peritoneum in each case. The authors explicitly caution that granulomatous inflammation and adhesiogenesis may be linked to how the agent was applied, noting that avoiding powder remnants through complete rinsing and using a gel transformation may be important. This paper is centrally about endometriosis — it reports granulomatous peritoneal inflammation and adhesion formation after potato starch-based anti-adhesive use in laparoscopic endometriosis surgery.

Abstract

BACKGROUND: Endometriosis is a chronic inflammatory oestrogen-dependent disease. It is characterised by elevated inflammatory markers in the peritoneal milieu with subsequent adhesiogenesis. Nowadays, excisional, and ablative surgeries are considered the main treatment of endometriosis, and adhesiolysis is being performed almost routinely during these procedures. Postoperative adhesion formation is a significant concern for many surgeons, especially as endometriosis patients are assumed to be predisposed to adhesiogenesis. In order to minimise adhesiogenesis after endometriosis surgery, the usage of different barrier methods have been discussed in the literature. Recent studies aim to investigate the effect of potato starch preparations on adhesion formation in endometriosis patients. OBJECTIVES: We aim to describe the findings of a second-look laparoscopy on patients who received a starch-based anti-adhesive agent. MATERIALS AND METHODS: We present a retrospective case series that included the medical, surgical, and histopathologic data of three patients. MAIN OUTCOME MEASURES: Intraperitoneal adhesion formation and peritoneal inflammation. RESULTS: All three patients had de-novo adhesions during the second-look laparoscopy. Pathological examination revealed noncaseating granulomatosis of the peritoneum in all patients. CONCLUSION: The use of potato starch-based agents as a peritoneal adhesion prophylaxis in laparoscopic endometriosis surgery could lead to granulomatous peritoneal inflammation. Correct application by avoiding powder remnants through complete rinsing and transformation to gel seems to be an important factor to avoid this adverse effect. WHAT IS NEW?: We aim to highlight that potato starch-based anti-adhesive agents similar to the one used in this study could be a cause of adhesiogenesis and peritoneal inflammation.

Abstract

Background: Endometriosis is a chronic inflammatory oestrogen-dependent disease. It is characterised by elevated inflammatory markers in the peritoneal milieu with subsequent adhesiogenesis. Nowadays, excisional, and ablative surgeries are considered the main treatment of endometriosis, and adhesiolysis is being performed almost routinely during these procedures. Postoperative adhesion formation is a significant concern for many surgeons, especially as endometriosis patients are assumed to be predisposed to adhesiogenesis. In order to minimise adhesiogenesis after endometriosis surgery, the usage of different barrier methods have been discussed in the literature. Recent studies aim to investigate the effect of potato starch preparations on adhesion formation in endometriosis patients.

Objectives

We aim to describe the findings of a second-look laparoscopy on patients who received a starch-based anti-adhesive agent.

Materials and methods

We present a retrospective case series that included the medical, surgical, and histopathologic data of three patients. Main Outcome Measures: Intraperitoneal adhesion formation and peritoneal inflammation.

Results

All three patients had de-novo adhesions during the second-look laparoscopy. Pathological examination revealed noncaseating granulomatosis of the peritoneum in all patients.

Conclusion

The use of potato starch-based agents as a peritoneal adhesion prophylaxis in laparoscopic endometriosis surgery could lead to granulomatous peritoneal inflammation. Correct application by avoiding powder remnants through complete rinsing and transformation to gel seems to be an important factor to avoid this adverse effect. What is new? We aim to highlight that potato starch-based anti-adhesive agents similar to the one used in this study could be a cause of adhesiogenesis and peritoneal inflammation.
