[A Case of Radical Resection after CapeOX Therapy for Locally Advanced Sigmoid Colon Cancer with Anemia and Abscess Formation in a Jehovah's Witness].

The patient-a Jehovah's Witness-was a woman in her 60s, with locally advanced sigmoid colon cancer. She had severe anemia, and a computed tomography scan of her abdomen showed a tumor with abscess formation and perforation that had invaded into the left urinary duct and the left ovary, without distant metastasis. It was difficult to perform curative resections without transfusion; therefore, CapeOX therapy was plannedas the neoadjuvant treatment. After 3 courses of CapeOX therapy, the patient's anemia improved, and the tumor and abscess had shrunk. Subsequently, a sigmoidectomy with D3 lymph node dissection, partial resection of the small intestine, and the left adnexectomy, as a radical surgery, were performed without blood transfusion. In cases of concomitant colon cancer with anemia that are treated with highly invasive surgery, it might be necessary to conduct systematic treatment in order to complete non-transfusion therapy.

Right-sided Bochdalek hernia in an elderly adult: a case report with a review of surgical management.

BACKGROUND: Bochdalek hernias are one of the most common types of diaphragmatic hernia, with most cases diagnosed during the neonatal period. In contrast, diagnosis of a Bochdalek hernia in an adult is rare and is typically observed on the left side of the diaphragm. Even more rare is the diagnosis of a right-sided Bochdalek hernia in an adult, where there is concurrent visceral malformation in most cases. CASE PRESENTATION: We describe a case of an 89-year-old female who presented with abdominal pain. An abdominal computed tomography (CT) scan showed decreased intravenous contrast uptake and thickening of the wall of herniated small intestine through the right side of the diaphragm, which led to the diagnosis of a strangulated diaphragmatic hernia. The patient underwent emergent laparotomy and required a partial resection of the necrotic ileum and a hernia repair with direct closure. Interestingly, in this case, organ malformation was not observed. The patient was discharged approximately 2 weeks after surgery without complication. CONCLUSIONS: Adult right-sided Bochdalek hernia with strangulation in the absence of hepatic atrophy is a rare entity. Considering the severity of this condition, accurate diagnosis and proper treatment are needed. A tailored operative approach is required on an individual case basis.

Totally laparoscopic anterior resection with transvaginal assistance and transvaginal specimen extraction: a technique for natural orifice surgery combined with reduced-port surgery.

BACKGROUND: Natural orifice specimen extraction (NOSE) has been developed as a means of decreasing the incidence of surgical wound complications. However, NOSE performed using a conventional multiport technique has been reported previously. The current authors performed totally laparoscopic anterior resection with transvaginal specimen extraction (TVSE) using the reduced-port surgery (RPS) technique. The Alexis wound retractor (Applied Medical, Rancho Santa Margarita, CA, USA) and Free Access (Top Corporation, Tokyo, Japan) were attached to the transvaginal route for transvaginal assistance and smooth specimen extraction. The authors documented this simple and safe technique and its short-term results. METHODS: Data were prospectively collected for five patients who underwent totally laparoscopic anterior resection with TVSE for colorectal cancer between June 2012 and December 2012. A multiport access device (GelPOINT advanced-access platform; Applied Medical) was inserted into the navel, and a 5-mm port was inserted into the right lower quadrant to be used as a drain site. Transverse transvaginal posterior colpotomy then was performed. One ring of an Alexis ring pair was inserted into the peritoneal cavity through the vagina. The other white ring was placed outside of the vagina and then covered with a Free Access to maintain the pneumoperitoneum for insertion of a 12-mm port. Lymph node dissection and transection of the distal colon were performed with transvaginal assistance. The specimen then was extracted transvaginally. After the Alexis had been removed, the vaginal incision was closed transvaginally. End-to-end colorectal anastomosis was performed using the double-stapling technique. RESULTS: Transvaginal extraction was completed in all five cases. The median operation time was 235 min. One case was complicated by chyloperitoneum. The median hospital stay was 6 days. Only one patient required intravenous analgesics once on postoperative day 1. All the patients remained disease free. CONCLUSION: Totally laparoscopic anterior resection using TVSE with RPS appears to be feasible, safe, and oncologically acceptable for selected cases.

[A case of hyperammonemic encephalopathy related to 5-FU in an aged patient with recurrent colon cancer treated with FOLFIRI therapy].

We report a case of hyperammonemic encephalopathy related to 5-FU in an aged patient with recurrent colon cancer treated with FOLFIRI therapy. An 80-year-old man underwent right hemicolectomy for cecal cancer. After 10 months, surgical resection was performed for its local recurrence. He was then treated with FOLFIRI therapy, and during the fifth course, he presented with a sudden onset of congestive disturbances. Through radiographic examination and laboratory data, only hyperammonemia was found; he was therefore diagnosed with hyperammonemic encephalopathy. By starting branchedamino acid solutions for its treatment, his consciousness and serum ammonia were promptly improved. Hyperammonemic encephalopathy related 5-FU is caused by increasing ammonia production and its metabolic inhibition, and is worsened by renal dysfunction, dehydration, constipation, infections, or body weight loss. On account of the potential decrease of metabolic function of liver and kidney, an aged person tends to have hyperammonnemia more than a youth. Clinicians should be aware of the adverse events associated with hyperammonemia when then administer a large amount of 5-FU to elderly patients.

Imatinib therapy for a patient with metastasis of colonic gastrointestinal stromal tumor: report of a case.

Gastrointestinal stromal tumors (GISTs) developing in the colon are rare, accounting for <5 % of all GISTs. There are few data on the clinical efficacy of tyrosine kinase inhibitors in colonic GISTs. We report here on an 80-year-old male patient with advanced GIST of the transverse colon. The patient underwent palliative resection of the primary tumor because the disease was associated with multiple liver metastases and peritoneal dissemination. Immunohistochemical analysis of the surgical specimens showed KIT and CD34 expression. Sequence analysis revealed that the tumor harbored deletion mutation at codons 557-558 in exon 11 of the c-kit gene. A diagnosis of colonic GIST was made. The patient postoperatively underwent imatinib therapy for the remaining metastatic tumors. Imatinib therapy induced a cyst-like appearance of the liver metastases and stabilized the disease. In the present case, c-kit gene analysis was found to be clinically helpful for validating the diagnosis and therapeutic decision making for this rare disease.

[A case of locally advanced rectal cancer had a pathological complete response to XELOX Therapy].

The patient was a 62-year-old man with bowel obstruction in a locally advanced rectal cancer. Computed tomography (CT) scan of the abdomen showed tumor enlargement(11.4 × 9.0 cm)that invaded the urinary bladder, but no distant metastasis. XELOX therapy was planned in order to shrink or eliminate the tumor after a sigmoid colostomy. Four courses of XELOX therapy were perfomed. Consequently, the level of the tumor marker had been restored to a normal range. CT scan revealed marked shrinkage of the tumor (6.1 × 5.2 cm) and a sharply-defined border between the tumor and the urinary bladder. Three weeks after chemotherapy, a low anterior resection as a radical surgery, and a temporary ileostomy were performed. The post-operative course was good. The histological effect was judged to be grade 3. There were no viable cancer cells in the rectal tumor and lymph nodes. The patient is alive and has been disease-free for 10 months after the operation. XELOX therapy as pre-operative chemotherapy might be safe and effective for patients with locally advanced rectal cancer.

Totally laparoscopic sigmoid colectomy with transanal specimen extraction.

BACKGROUND: Conventional techniques for laparoscopic-assisted colectomy (LAC) require abdominal minilaparotomy for extraction of the specimen. Abdominal wound complications often increase the invasiveness of LAC. To decrease the incidence of wound complications, natural orifice specimen extraction (NOSE) has been reported. However, only a few devices that allow smooth extraction and reduced intracorporeal contamination have been reported previously. We performed totally laparoscopic sigmoid colectomy using transanal specimen extraction (TASE) and the Alexis(®) wound retractor (Applied Medical, Rancho Santa Margarita, CA, USA). We document this simple and safe technique and its short-term results. METHODS: We prospectively collected data on 18 patients who underwent totally laparoscopic sigmoid colectomy with TASE from April 2009 to July 2010. Lymph node dissection and transection of proximal and distal colon were performed in conventional manner. The transected rectal stump was opened transversely, and a long Babcock grasper was inserted transanally through the opened rectal stump. One of a pair of Alexis rings was held and pulled out of the anus. The other ring was placed in the opened rectal stump. The specimen was then extracted transanally through the Alexis. After the Alexis had been removed, the rectal opening was reclosed with a linear stapler. End-to-end colorectal anastomosis was then performed using the double-stapling technique. RESULTS: Transanal extraction was achieved in 17 cases. We switched to conventional LAC in a case involving a bulky specimen. In 16 cases not including the combined cholecystectomy case, mean operation time was 241 min. One case was complicated by anastomotic leakage and wound infection, while another had enterocolitis. Median hospital stay was 6 days. All patients remained disease free. Mean Wexner score at 12 months after operation was 2.3. CONCLUSION: Totally laparoscopic sigmoid colectomy using TASE and the Alexis appears to be feasible, safe, and oncologically acceptable for selected cases.

[A case of fungal pyogenic spondylitis with ulcerative colitis].

A 58-year-old man with refractory ulcerative colitis underwent subtotal colectomy 4 months after the diagnosis. He developed intense back pain and high fever 9 days after the operation. Findings of a CT scan and an MRI confirmed the diagnosis of pyogenic spondylitis, and Candida albicans was cultured from the biopsy specimen. His clinical condition gradually improved after receiving therapy with rest and antifungal agents. Physicians should be aware of the possibility of pyogenic spondylitis in patients with back pain is treated for ulcerative colitis.
