Reduction en masse can be treated using pure laparoscopic transabdominal preperitoneal hernioplasty following early CT diagnosis: report of a case.

Reduction en masse refers to the rare occurrence of an incarcerated inguinal hernia arising from the manual reduction of a hernia. Such a condition constitutes a medical emergency because the hernia contents, such as the small bowel, remain strangulated in the preperitoneal space. Therefore, an early and accurate diagnosis, with early treatment, is important. A 61-year-old Japanese man presented with an irreducible lump over his left groin, leading to the reduction of an incarcerated inguinal hernia by a doctor at another hospital. Later, he was admitted to our hospital with vomiting and abdominal pain. Computed tomography showed a ball-like lesion containing an incarcerated bowel loop over his left pelvis. The patient was diagnosed with an incarcerated small bowel obstruction due to a reduction en masse; a laparoscopic transabdominal preperitoneal (TAPP) hernioplasty was performed. TAPP hernioplasty is a safe method for treating reductions en masse that allows confirmation of bowel viability.

Prospective longitudinal evaluation of quality of life in patients with permanent colostomy after curative resection for rectal cancer: a preliminary study.

PURPOSE: The aim of this study was to evaluate health-related quality of life in patients with a colostomy immediately before and during the first year after surgery. SUBJECTS AND SETTING: Patients (aged ≥20 years) who were diagnosed with rectal cancer and scheduled to undergo curative surgery with a permanent colostomy were recruited for this study. Data were collected at 2 university hospitals in Tokyo. METHODS: Participants were asked to complete a self-administered questionnaire regarding health-related quality of life before surgery and a mailed or hand delivered questionnaire to evaluate quality of life at 2, 6, and 12 months after surgery using the Short Form-36 version 2. For patients who responded at all 4 time points, the scores at each time point were compared using paired t tests to examine longitudinal changes in quality of life after surgery. RESULTS: Mean quality-of-life scores in most domains before surgery and during the first year after surgery were lower than the normal control in the norm-based scoring method. Scores at 2 months after surgery were lower than those before surgery. At 12 months after surgery, however, quality-of-life scores improved almost to the level observed before surgery, with the exception of the score in the social functioning domain. Statistical differences in scores between the time points of the survey were observed in the role-physical, bodily pain, and mental health domains. CONCLUSIONS: These results suggest that patients with permanent colostomy after curative resection for rectal cancer need additional medical support and care before surgery and during the first year after surgery.

[A case of colonic neuroendocrine carcinoma with severe liver dysfunction by multiple liver metastases successfully treated with hepatic arterial infusion].

A 63-year-old male was diagnosed as ascending colon cancer with severe liver dysfunction caused by multiple liver metastases. Initially, hepatic arterial infusion (HAI) chemotherapy was started to reduce the size of metastatic tumors and to prevent a liver failure. After 7 courses of HAI chemotherapy, he recovered from liver dysfunction, and underwent right hemicolectomy. Pathological examination of the resected specimen revealed the tumor was neuroendocrine carcinoma. After surgery, a systemic infusion of mFOLFOX6/bevacizumab regimen was started. A partial response (PR) of metastatic lesions was observed. Irinotecan/cetuximab was administered as the second-line. He survived for 10 months after HAI. HAI for colonic neuroendocrine carcinoma with severe liver dysfunction by multiple liver metastases might be benefitial to prevent a liver failure.

[Clinical characteristics of cancer of unknown primary (CUP)--a summary of 22 cases].

Cancer of unknown primary site (CUP) is not a rare entity and accounts for 3-5% of all malignant neoplasias. CUPs are diagnosed with metastatic lesion so they are all in the advanced stage. Systemic chemotherapy is applied in many cases, but the ideal therapeutic strategy has not yet been determined. CUP shows much histological and therapeutic heterogeneity. Histologically, half of CUPs are adenocarcinoma and the rest are undifferentiated carcinomas. We analyzed the clinical and therapeutic characteristics 22 cases of CUP patients. Most CUP patients are found from lymph node swelling. There is no significant tendency as to the site of lymph node metastasis. Bone metastases are frequently encountered. It seems undifferentiated carcinomas are more responsive to chemotherapy. Chemo-sensitive patients are likely to have a longer life expectancy. In our experience all of the chemo-responsive cases are treated with platinum-based chemotherapy. Today several platinum-based combination chemotherapies are reported, but there is no large-scale randomized study. Because of its variety, individualized therapy may be ideal for CUP.

AFP-producing hepatoid adenocarcinoma in association with Barrett's esophagus with multiple liver metastasis responding to paclitaxel/CDDP: a case report.

A case of alpha-fetoprotein (AFP)-producing hepatoid adenocarcinoma in association with Barrett's esophagus with multiple liver metastases, responding to chemotherapy, is reported. A 47-year-old man was admitted to our hospital with abdominal pain after subtotal esophagectomy for an esophageal adenocarcinoma in association with Barrett's esophagus, and was diagnosed as having multiple liver tumors. Most tumor markers were normal, but the serum AFP level was markedly elevated. Dynamic computed tomography and ferumoxide enhanced magnetic resonance imaging did not provide evidence of any primary hepatocellular carcinoma. Since microscopic examination of the resected tumor showed a poorly-differentiated adenocarcinoma with hepatoid features displaying AFP-immunoreactivity, the liver tumors were thus considered to be metastatic deposits. Surgery was not feasible so chemotherapeutic agents were tried, and the combination of paclitaxel (TXL) and cisplatin (CDDP) gave a partial response and good control for a period. This is the first report, to our knowledge, of effective chemotherapy for liver metastases from an AFP-producing hepatoid adenocarcinoma of the esophagus.

Alpha-FP normalization as a prognostic factor for mediastinal origin embryonal carcinoma: report of five cases.

It is well known that a subgroup of germ cell tumors, embryonal carcinoma of extra-gonadal origin have a poor prognosis. We have encountered five cases of mediastinal embryonal carcinoma treated with high-dose chemotherapy (HD-CT) supported by auto-PBSCT in four, and resection in three. Our cases indicated that normalization of the alpha-FP tumor marker level during standard chemotherapy is a very important factor for cure, and the resection of the residual mass after chemotherapy is indicated due to the great risk of remnant malignant cells despite HD-CT.
