Single-incision laparoscopic partial cecectomy for appendiceal mucocele in a patient with porphyria photosensitivity

Erythropoietic protoporphyria (EPP) is a rare hereditary subtype of cutaneous porphyria characterized by photosensitivity. Increased exposure to light irradiation may precipitate acute liver failure, and surgical light-induced intestinal burns and perforations are known to occur. We report a case of EPP in a patient who underwent laparoscopic partial cecectomy for appendiceal mucocele. A 55-year-old man with EPP was presented for treatment of appendiceal mucocele. A light test using two types of laparoscopes (Companies O and S) was performed preoperatively. Light from the laparoscope manufactured by Company O caused photosensitivity; this effect was not observed with light from the laparoscope manufactured by Company S. Therefore, we performed laparoscopic partial cecectomy through a single umbilical incision using the laparoscope from Company S. Except for the incision site, the patient's skin was completely covered using surgical drapes. No intra- or postoperative complications were observed. Histopathological examination of the resected specimen revealed a low-grade appendiceal mucinous neoplasm.

Automated summary

Erythropoietic protoporphyria (EPP) is a rare hereditary skin disease characterized by photosensitivity. We report a case of EPP patient who underwent laparoscopic surgery using a laparoscope that did not cause photosensitivity. The surgery was successful without any complications.
