We herein report the case of a patient with a cecal cancer with simultaneous liver, spleen, and ovarian metastases as well as peritoneal dissemination who achieved a long-term survival. The patient was a 67-year-old female. Ileocecal resection with partial hepatectomy, splenectomy, simple total hysterectomy, bilateral salpingo-oophorectomy, and resection of the peritoneal dissemination were performed. The final diagnosis was Stage IV (T4a, N1, M1b[H1, P3, OTH]). Adjuvant chemotherapy was administered, but abdominal computed tomography(CT)revealed a metachronous liver metastasis 41 months later. We performed partial hepatectomy, and the patient continued adjuvant chemotherapy. The patient is currently alive and disease-free 30 months after the last operation, 72 months after the initial surgery.

A 66-year-old woman underwent total pelvic exenteration for a pelvic tumor. The pathological diagnosis was sigmoid colon cancer T4b(in the small intestine, uterus, and vagina), N0, M0, Stage II . The patient was treated with XELOX for 6 months as adjuvant chemotherapy and was then treated with IRIS for another 6 months. Brain metastasis developed in the left occipital lobe after 12 months, and she underwent craniotomy and enucleation of the tumor. Liver metastasis and peritoneal dissemination metastasis developed 16 months after her initial diagnosis. The patient underwent re-craniotomy and radiotherapy for recurrence of the brain metastasis 18 months after diagnosis and started taking TAS-102 3 months later. She began treatment with CPT-11 plus panitumumab 24 months after diagnosis, and the dose was increased 9 months later(ie, 35 months after the initial diagnosis). The patient remains alive 42 months after surgery.

We report our experiences of a case of repeated bleeding after hemorrhoid ligation. A 53-year-old man underwent hemorrhoid ligation for internal hemorrhoids at another hospital. Postoperatively, he developed severe and repeated bleeding. Scanning revealed extrahepatic portal venous obstruction. The severe bleeding persisted after transfer to our institution, where we re-sutured the ligature and performed superior rectal artery embolism, leading to arrest of bleeding. The rectal varix arose due to portal hypertension, which resulted in the diagnosis of idiopathic extrahepatic portal vein obstruction.

The authors present a case of rectal carcinoid tumor with lateral lymph node metastases and liver metastases that was successfully treated by 4 resections. A 70-year-old man was diagnosed with a rectal carcinoid tumor (20 mm in diameter) with submucosal (SM) invasion. Radical resection was performed at 25 months, 38 months, and 57 months, when abdominal computed tomography (CT) revealed metachronous liver metastases of the rectal carcinoid tumor. At 50 months, metachronous lateral lymph node metastases were also revealed. Three hepatectomies and a laparoscopic lateral lymph node dissection were performed. The patient is currently free of disease at 25 months after the last intervention.

Purpose: The purpose of this study was to evaluate the clinicopathological features of mucinous adenocarcinoma associated with perianal fistulas (MAF), to assess the importance of preoperative MRI analysis, and to determine the optimal surgery., Methods: We performed a retrospective analysis of the data from seven patients with MAF treated at our hospital between 2000 and 2013, and herein discuss the importance of preoperative magnetic resonance imaging (MRI) and of radical surgery., Results: The male to female ratio was 5:2, and the mean age of the patients was 63 years old (28-70). The median duration of chronic fistulation was 16 years (5-40). The tumor extension was classified as II+III+IV in five patients and as II+III in 2 patients according to the Sumikoshi classification, as determned by pelvic MRI. The performed surgeries were 3 abdominoperineal resections with sacral resection and 4 pelvic exenterations with sacral resection. Two local recurrences developed in patients with R1 resection, and 1 distant metastasis occurred in 1 patient with R0 resection., Conclusion: For patients with MAF, a curative surgical resection is the only definitive treatment that can be expected to provide a good prognosis. The application of the Sumikoshi classification using MRI may provide a precise assessment of the extension of MAF, which can allow the appropriate surgery to be selected for the patients with MAF.

Objective: To introduce the prophylactic laparoscopic lateral pelvic lymph node dissection performing by remarking the vesicohypogastric fascia following total mesorectal excision for patients with advanced lower rectal cancer without radiological evidence of lymph node involvement., Surgical Method: We set 5 ports for conventional laparoscopic rectal surgery. During the prophylactic laparoscopic lateral pelvic lymph node dissection, we retrieved the lymph nodes from the internal iliac area and obturator area. We recognized the pelvic nerve plexus, vesicohypogastric fascia (including internal iliac vessels), and parietal fascia (psoas muscle fascia, pubic bone and internal obturator muscle fascia) as the dissection borders from internal to external. Of note, the vesicohypogastric fascia can be recognized under magnified clear vision, and can be preserved by precise dissection, resulting in reduced hemorrhage from the internal iliac vessels and complications such as urinary dysfunction., Conclusion: Prophylactic laparoscopic lateral pelvic lymph node dissection after remarking on the vesicohypogastric fascia may contribute to a less invasive surgery compared with conventional laparoscopic lateral pelvic lymph node dissection.

Endoscopic submucosal dissection involves dissecting manipulation performed with tumors in an exposed condition for a long period of time. Thus, there is a risk for implantation of tumor cells. The objectives of this study were to examine exfoliated tumor cells after colorectal endoscopic submucosal dissection and to elucidate the effectiveness of intraluminal lavage to remove these cells. The subjects were 8 patients who had undergone colorectal endoscopic submucosal dissection at our hospital between September and December 2012. A retrospective study was conducted on the cytological findings of intraluminal lavage samples in these patients. Seven of the 8 patients (88%) had exfoliated tumor cells in the lavage samples at the beginning of lavage. Only 3 patients (3 8%) had exfoliated tumor cells after lavage with 300 ml of water. A large number of tumor cells were thought to have exfoliated into the intestinal lumen after endoscopic submucosal dissection. Sufficient intraluminal lavage after colorectal endoscopic submucosal dissection is necessary to remove exfoliated tumor cells.

Radical surgery is often necessary in patients with local recurrence of rectal cancer or in those with carcinoma associated with an anal fistula. The surgery may include extended excision of the perineal area and can create a large dead space in the pelvis and a large skin defect, often necessitating reconstruction of the pelvic floor using rectus abdominis musculocutaneous (RAM) flap transposition. Wound dehiscence and incisional hernia are common complications of RAM flap transposition. We report herein our encounter with 3 patients in whom we used a "sliding door" technique for reconstruction of the abdominal wall after the creation of a RAM flap. One patient underwent abdominoperineal resection with sacrectomy and RAM flap transposition; he experienced a postoperative surgical site infection and wound dehiscence, which we urgently repaired by reconstructing the abdominal wall using the sliding door technique. Two other patients underwent posterior pelvic exenteration with sacrectomy and RAM flap transposition. These patients underwent simultaneous abdominal wall reconstruction using the sliding door technique. No patient experienced postoperative pelvic sepsis, wound dehiscence, or incisional hernia. The sliding door technique might be useful for preventing wound dehiscence and incisional hernia in patients undergoing RAM flap transposition.

Objective: The aim of this study was to evaluate the outcomes of patients who underwent extensive pelvic surgery for locally advanced primary or recurrent non-colorectal pelvic malignancies., Patients and Methods: We performed a retrospective review of the medical records of 19 patients with non-colorectal pelvic malignancies who underwent extensive surgery at our institution between January 2005 and May 2013. Overall survival and progression-free survival were estimated using the Kaplan-Meier method and compared using the logrank test., Results: With regard to tumor histology, 6 patients (31.6%) had gynecological tumors, 8( 42.1%) had urological tumors, 2( 10.5%) had sarcomas, and 3( 15.8%) had other malignancies. Total pelvic exenteration was performed in 13 patients (68.4%), and other procedures were performed in 6 patients( 31.6%). For all patients, the median operation time and blood loss were 699 min and 2,930 mL, respectively. Complete tumor resection( R0) was achieved in 13 patients( 68.4%), and 16 patients had complications( 84.2%). The median overall survival was 18.5 months for patients who underwent R0 resection, compared with 7.3 months for those who underwent R1/R2 surgery (p=0.113), and the median progression-free survival was 7.3 months for cases of R0 resection, compared with 2.0 months for cases of R1/R2 surgery (p=0.035)., Conclusion: Our findings indicate that extensive pelvic surgery may be an optimal treatment for some patients with locally advanced primary or recurrent non-colorectal pelvic malignancies. Careful patient selection according to oncological, anatomical, and patient-related factors may improve the outcomes of patients undergoing this extensive, aggressive pelvic surgical procedure.

Aim: To evaluate the technical feasibility of laparoscopic lateral pelvic lymph node dissection (LPLD) following total mesorectal excision (TME) as prophylaxis for patients with advanced lower rectal cancer but no radiologic evidence of lymph node involvement., Patients and Methods: TME was performed on 30 patients with cT3N1-2M0 lower rectal cancer. LPLD was performed by laparoscopic surgery in 12 patients (LAP group),and open surgery in 18 patients (Open group). Statistical analysis was used to compare the number of harvested lymph nodes, operative time, operative blood loss, transfusion rate, and volume of transfusion between the groups., Results: No significant difference was observed in the number of harvested lymph nodes. Operative time was significantly longer in the LAP group; however, operative blood loss, transfusion rate, and volume of transfusion were significantly lower in the LAP group., Conclusion: Laparoscopic LPLD, when performed by a well-trained laparoscopic team, is safe and feasible in some selected lower rectal cancer patients. This approach has the potential to achieve oncologic lymph node clearance equivalent to open surgical LPLD, and to overcome the cited disadvantages of LPLD, which include greater operative blood loss and urinary dysfunction.

A 63-year-old woman was admitted to our hospital because of tarry stool several years previously. At the time, café-au-lait spots and dermal nodules were found on her entire body, and a diagnosis of von Recklinghausen disease was established. Small bowel endoscopy revealed a submucosal tumor in the jejunum. Laparotomy was therefore performed on the suspicion of intestinal GIST. Numerous extramural tumors with a diameter of 3-5mm were observed along the jejunum and ileum, in addition to the primary tumor. Partial resection of the jejunum, including the primary tumor and only one small nodule was performed to prevent short bowel syndrome. Immunopathological studies of the tumors were positive for KIT and CD34 and we diagnosed multiple intestinal GISTs. Imatinib mesylate was not administered, but no growth of the residual tumors have been recognized for 10 months after surgery.
