ABSTRACT
BACKGROUND: Although sacrococcygeal teratoma (SCT) is relatively common in children, it is rare in adults. The prognosis for malignant cases is poor, so prompt surgical resection is required. Transabdominal and transsacral approaches are common approaches for tumor resection. In recent years, there have been reports of tumor removal with laparoscopic assistance, but all have applied transabdominal approaches. CASE PRESENTATION: A 27-year-old woman visited our gynecology department because of abdominal pain and genital bleeding. Magnetic resonance imaging (MRI) revealed a 3-cm-sized cystic mass in the left retrorectal area, and she was referred to our department for detailed examinations and treatment. She was diagnosed with a presacral cystic tumor and decided to undergo surgery. We used a transsacral approach to perform tumor excision. Since it was difficult to confirm the deep part of the tumor through direct visualization, we used GelPOINT® Path (a transanal access platform) and AirSEAL® System (insufflation device) to remove the tumor endoscopically. The postoperative course was uneventful with no bladder or rectal dysfunction. Histopathological examination revealed a mature teratoma. CONCLUSIONS: When the tumor is relatively small and located in the lower sacrum, the endoscopically assisted transsacral approach can establish a stable field of view by expanding the depth of the surgical field. This method is useful considering its ability to perform excision without leaving residual tumor tissue and satisfactory safety and cosmetic results.
ABSTRACT
INTRODUCTION: Enema examination is considered safe, but in rare cases, complications may result. Here, we report a rare case of iatrogenic bowel perforation during enema examination through a colostomy without leakage of contrast agent. PRESENTATION OF CASE: A 36-year-old man who had undergone a sigmoid loop colostomy was diagnosed with ulcerative colitis. A bowel enema through a colostomy was performed by nurses and radiological technologists. During the procedure, a balloon catheter was inserted into the proximal lumen of the colostomy, and the balloon was inflated. The patient developed severe abdominal pain a few minutes following withdrawal of the catheter. Computed tomography showed intraperitoneal free air, although contrast agent leakage into the intraperitoneal cavity was not observed. The patient underwent emergency laparotomy. Intraoperatively, there was a 3-cm bowel perforation just inside the colostomy where the inflated balloon was pressing. DISCUSSION: The perforation site may have been sealed by the inflated balloon during the enema examination. In addition, the patient maintained a supine position during and after the examination. This led to contrast agent accumulating on the dorsal side and not leaking out from the perforation site after the balloon was deflated. CONCLUSION: Iatrogenic bowel perforation can occur without leakage of contrast agent during enema examination through a colostomy, and the examination should be performed under the supervision of an attending doctor. In the case of an enema examination through a colostomy, clinicians must be aware of the possibility of bowel perforation even if leakage of contrast agent is not observed.
ABSTRACT
BACKGROUND: Douche injury is a rare consequence of water recreation activities. Generally, this type of trauma occurs when people fall into the water in a sitting position during high-speed activities such as using a personal watercraft (PWC). Here, we report a rare case of anorectal injury caused by water jets from a PWC during sudden acceleration from rest. CASE PRESENTATION: A 21-year-old male passenger on a PWC fell off backward from the rear seat when the craft suddenly accelerated. He fell into the water in a supine position with his legs open, and the water jets of the PWC struck his perineum directly. Thereafter, bleeding from the anus was seen, and he was transferred to our hospital. On physical examination, there was a deep laceration interrupting the external anal sphincter in the posterior rectal wall. Abdominal computed tomography revealed a full-layer perforation of the posterior rectal wall and leakage of feces into the extraperitoneal space, but intraperitoneal free air was not seen. Laparoscopic sigmoid loop colostomy and primary suturing of the sphincter and mucosa were performed. He did not have any complications and was discharged from our hospital 16 days after the surgery. His anal function was almost perfectly preserved, and his diverting colostomy was closed 4 months later. CONCLUSION: Anorectal injuries related to PWCs can occur not only while traveling at high speeds, but also when suddenly accelerating from rest. A diverting colostomy should be performed for this type of trauma. In these trauma cases, clinicians must suspect complex and life-threatening anorectal injuries early.
ABSTRACT
We report the frequency of lacrimal passage disorder and the outcomes of treatment. This retrospective study was performed on 55 cases that were treated with S-1 for at least 1 month. We asked patients about ocular symptoms. An ophthalmic surgeon examined all patients and diagnosed lacrimal passage disorder in 6 of 55 patients (12. 5%). The mean dose of S- 1 was 10, 300 mg, and the average period to onset of lacrimal passage disorder was 5. 7 months. The causes of epiphora included occlusion/stenosis of lacrimal canaliculus, occlusion of lacrimal puncta and stenosis of nasolacrimal duct. Lacrimal surgery was performed in all 6 patients and epiphora improved. Lacrimal passage disorder may result from systemic treatment of patients with S-1. Symptoms of lacrimal passage disorder improved with early detection and treatment by insertion of a silicone tube.
