Incarcerated Small Bowel Herniation in a Stoma Mimicking Sigmoid End Colostomy Prolapse.

Introduction: A stoma prolapse is easy to diagnose by visual examination, and it rarely incarcerates. Therefore, manual reduction is usually performed as soon as the diagnosis is made. In this report, we describe a case of stoma prolapse that could not be reduced manually and ruptured because an incarcerated parastomal hernia occurred in the stoma, mimicking stoma prolapse. Case Presentation: A 66-year-old woman underwent total hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, omentectomy, resection of dissemination, and low anterior resection with formation of a sigmoid end colostomy for endometrial cancer with infiltration of the rectum. Fourteen months after the initial operation, she presented with stoma prolapse and multiple episodes of vomiting. The prolapsed stoma was 20 cm in length, appeared swollen and edematous, and was somewhat firm. Although it looked viable, some of the mucosa was darkish red, indicating congestion. Therefore, the diagnosis was sigmoid end colostomy prolapse with an ischemic component. An attempt at manual reduction resulted in rupture, so an emergency laparotomy was performed. Intraoperatively, we found that the ileum was incarcerated in the aperture created where the colostomy had been formed. When the incarcerated ileum was released, the stoma prolapse could be reduced easily. The end colostomy was refashioned in the left upper quadrant of the abdomen. Conclusion: An incarcerated parastomal hernia can mimic stoma prolapse. If the findings differ from those of typical stoma prolapse, imaging should be performed to confirm whether another clinical entity is involved in the stoma prolapse.

[Long-Term Complete Response in Postoperative Multiple Lung and Mediastinal Lymph Node Metastases of Esophageal Cancer Using Systemic Chemotherapy with DCF Treatment - A Case Report].

A 59-year-old man was diagnosed with advanced thoracic esophageal cancer.He underwent neoadjuvant chemotherapy with cisplatin(CDDP), 5-fluorouracil(5-FU)(CF)followed by transthoracic esophagectomy with three-field lymphadenectomy. Histopathological examination revealed that the tumor was poorly differentiated squamous cell carcinoma invading the adventitia with 6 regional lymph node metastases.Four months after surgery, follow-up thoracic computed tomography (CT)showed multiple lung and mediastinal lymph node metastases.The patient's general condition was favorable, and he underwent systemic chemotherapy with docetaxel, CDDP, 5-FU(DCF).After 2 courses of DCF, chest CT revealed that the lung and mediastinal lymph node metastases had markedly decreased in size to the point of being unmeasurable.After receiving additional chemotherapy consisting of 2 courses of DCF and 8 courses of monthly docetaxel, the patient has been followed up without treatment.No tumor re-recurrence has occurred in the 6 years and 8 months since the first recurrence.In cases of recurrent or unresectable esophageal cancer, the rate of clinical response is reported to be higher for DCF than for CF. DCF is a tolerable regimen, even for postoperative patients, provided that monitoring is conducted for severe adverse events. In patients whose general conditions are favorable, DCF should be considered as a treatment option for recurrent esophageal cancer.
