A rare presentation of large bowel obstruction post haemorrhoidectomy: a case report

Abstract

Abstract Background Hemorrhoidal disease is a common anorectal pathology. Complications post hemorrhoidectomy are rare. Postoperative complications following hemorrhoidectomy include bleeding (2%), infection (0.4–8%), urinary retention (15%), and constipation (15–30%). Case presentation A 40-year-old of Asian background female presented to a tertiary colorectal service with large bowel obstruction post hemorrhoidectomy. This is the first case in the surgical literature describing large bowel obstruction secondary to extrinsic compression from urinary retention following hemorrhoidectomy. The patient developed urinary retention and obstructed defecation in setting of inadequate analgesia post hemorrhoidectomy. The patient required indwelling catheter insertion and aggressive constipation management to resolve symptoms. Histopathology from the hemorrhoidectomy did not reveal a malignancy. Conclusion Anesthetic choice and postoperative analgesia are important factors to avoid the development of complications. A missed malignancy diagnosis must always be excluded with patients presenting post hemorroidectomy with bowel obstruction.
