Japanese Practice Guidelines for Fecal Incontinence Part 3 -Surgical Treatment for Fecal Incontinence, Fecal Incontinence in a Special Conditions- English Version.

In Japan, the surgical treatment for fecal incontinence (FI) can be performed using minimally invasive surgery, such as anal sphincteroplasty and sacral neuromodulation (SNM), as well as antegrade continence enema (ACE), graciloplasty, and stoma construction. In addition, currently, several other procedures, including biomaterial injection therapy, artificial bowel sphincter (ABS), and magnetic anal sphincter (MAS), are unavailable in Japan but are performed in Western countries. The evidence level of surgical treatment for FI is generally low, except for novel procedures, such as SNM, which was covered by health insurance in Japan since 2014. Although the surgical treatment algorithm for FI has been chronologically modified, it should be sequentially selected, starting from the most minimally invasive procedure, as FI is a benign condition. Injuries to the neural system or spinal cord often cause disorders of the sensory and motor nerves that innervate the anus, rectum, and pelvic floor, leading to the difficulty in controlling bowel movement or FI and/or constipation. FI and constipation are closely associated; when one improves, the other tends to deteriorate. Patients with severe cognitive impairment may present with active soiling, referred to as "incontinence" episodes that occur as a consequence of abnormal behavior, and may also experience passive soiling.

Clinical pharmacology of daikenchuto assessed by transit analysis using radiopaque markers in patients with colon cancer undergoing open surgery: a multicenter double-blind randomized placebo-controlled study (JFMC39-0902 additional study).

BACKGROUND: This exploratory trial was conducted to investigate whether daikenchuto accelerates the recovery of gastrointestinal function in patients undergoing open surgery for sigmoid or rectosigmoid cancer. METHODS: Eighty-eight patients who underwent colectomy at one of the 11 clinical trial sites in Japan from January 2009 to June 2011 were registered in the study. Patients received either placebo or daikenchuto (15.0 g/day, 5 g three times a day) from postoperative day 2 to postoperative day 8. The study end points included the gastrointestinal tract transit time evaluated with radiopaque markers and the time to first flatus. The safety profile of daikenchuto was also evaluated until postoperative day 8. RESULTS: Seventy-one patients (daikenchuto, n = 38; placebo, n = 33) were statistically analyzed. Although the number of radiopaque markers in the anal side of the small intestine at 6 h was significantly greater in the daikenchuto group than in the placebo group (15.19 vs 10.06, p = 0.008), the total transit analysis results and the mean time to first flatus did not differ significantly between the two groups. CONCLUSIONS: Daikenchuto has a positive effect on the resolution of delayed gastric emptying, but has a limited effect on the resolution of postoperative paralytic ileus after open surgery in patients with sigmoid or rectosigmoid cancer. Daikenchuto may contribute to early oral intake in the postoperative course.

Granulocyte-colony stimulating factor producing anaplastic carcinoma of the pancreas treated by distal pancreatectomy and chemotherapy: report of a case.

Granulocyte-colony stimulating factor (G-CSF) producing pancreatic cancers are extremely rare. These tumors have an aggressive clinical course but no established treatment. We encountered a patient with a G-CSF-induced pancreatic cancer who was treated by surgical resection, followed by steroid treatment and chemotherapy. A 68-year-old Asian male presented at a local hospital with a 3-month history of fever, loss of appetite, and 10-kg weight loss. Laboratory data showed leukocytosis and elevation of C-reactive protein. Computed tomography (CT) revealed a 50-mm mass in the tail of the pancreas, but no signs of infective foci. He was transferred to our hospital for further evaluation. Contrast-enhanced CT showed rapid growth of this tumor over 1 week, and (18) F-2-fluoro-2-deoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) showed FDG accumulation in the tail of the pancreas (SUV max, 17.1) but at no other sites in his body. Magnetic resonance imaging showed a heterogeneous mass, similar to that observed by CT. Three weeks later, the patient underwent a distal pancreatectomy with splenectomy. The resected specimen was 154 mm in diameter, a threefold increase from the initial image. Histopathological examination identified the tumor as an anaplastic carcinoma of the pancreas. Following surgery, his leukocyte count and body temperature were reduced. He recovered well and was discharged from our hospital on postoperative day 18. Immunohistochemical expression of G-CSF in the resected specimen and elevated serum G-CSF concentration confirmed that the mass was a G-CSF producing anaplastic carcinoma of the pancreas. Subsequently, the patient experienced a high fever and loss of appetite. CT showed recurrence of cancer in the abdominal cavity, for which he was started immediately on tegafur-gimeracil-oteracil potassium combination S-1 and steroid. Unfortunately, he died on postoperative day 83. To our knowledge, this patient was the first with a G-CSF producing anaplastic carcinoma of the pancreas to be treated by surgical resection, steroid and adjuvant chemotherapy.

[Two Patients with Recurrence of Hepatocellular Carcinoma after Liver Resection Who Achieved Long-Term Stable Disease with Small Doses of Sorafenib Therapy].

Case 1: A6 4-year-old man with hepatocellular carcinoma (HCC) had received local therapy repeatedly for 20 years. In 2012, he underwent hepatic right lobectomy for recurrence of HCC. Multiple recurrences were found in the hepatic remnant, and transcatheter arterial chemoembolization (TACE) was performed. Considering his condition, a small dose of sorafenib (200 mg per day) was administered. He complained of general fatigue, so we prolonged the administration interval (200 mg every other day). Thereafter, compliance improved and long-term stable disease (long SD), for more than 6 months, long SD was achieved. Case 2: A7 5-year-old man with HCC was treated by TACE repeatedly for multiple recurrences after liver resection (segment 6). In 2008, metastases to the thoracic vertebra and left rib were treated by radiation therapy and radiofrequency ablation, respectively. Subsequently, sorafenib (400 mg per day) was administered. We reduced the dose of sorafenib to less than 400 mg per day because of diarrhea, hypertension, and general fatigue. Thereafter, long SD was achieved despite the small dose of sorafenib. We report here 2 cases of HCC where we achieved long SD in spite of treating with a small dose of sorafenib.
