TLDG can be performed safely after appropriate experience with LADG. Our results imply that TLDG may lead to faster recovery, better cosmesis, and improved quality of life in the short-term compared with LADG. Because of the limitations of a retrospective analysis on the study and a patient selection bias, a prospective randomized study should be conducted to reach definitive conclusions.

A 28-year-old man with no previous history of abdominal surgery presented at a local hospital with abdominal pain. He was diagnosed to have an intestinal obstruction and was treated conservatively. However, the symptoms persisted, and he was thereafter referred to this hospital. Plain abdominal radiographs demonstrated small-bowel gas. A computed tomographic scan of the abdomen disclosed wall thickening of an edematous, fluid-filled ileum. An exploratory laparotomy was performed to determine the cause of the intestinal obstruction. The ileum had herniated into the intersigmoid fossa, 100 cm proximal to the ileocecal valve, and the patient was diagnosed to have an intersigmoid hernia. Since the incarcerated portion of the small bowel was viable, reduction of the hernia and closure of the defect in the sigmoid mesocolon were performed. The postoperative course was uneventful. A sigmoid mesocolon hernia is an uncommon condition. This report presents a case of intersigmoid hernia and a review of 60 cases of sigmoid mesocolon hernia reported in Japan.

EAGLE was a randomized, multicenter phase III study which evaluated the superiority of bevacizumab 10 mg/kg plus FOLFIRI compared with bevacizumab 5 mg/kg plus FOLFIRI in patients with mCRC previously treated with first-line bevacizumab plus an oxaliplatin-based regimen. The results suggest that the higher 10 mg/kg dose offers no clear clinical benefit compared with bevacizumab 5 mg/kg in this setting.

We report a unique case of giant obstructing inflammatory polyposis associated with ulcerative colitis (UC). A 25-year-old Japanese man with an UC history of 2 years and 6 months was referred to our institution because of diarrhea and melena. His computed tomography scan showed marked dilation of the transverse and descending colon; therefore, we performed total colectomy. Macroscopic evaluation of the excised specimen indicated constricting lesions with giant polyposis in the transverse and descending colon. The polyposis consisted of narrow worm- or noodle-like polyps that bridged over the irregular ulcers. Histologic evaluation of the excised specimen indicated transmural inflammation with a thickened proper muscular layer overlaid with inflammatory polyposis. Based on these data, a diagnosis of giant inflammatory polyposis should be considered in patients who have had UC. Although giant inflammatory polyposis is considered benign, surgical treatment may be indicated to avoid serious complications.

BackgroundThe oxaliplatin-based regimen FOLFOX is widely used to treat patients with advanced colorectal cancer (CRC). However, dose-limiting toxicity after continuous oxaliplatin administration can lead to peripheral neuropathy. Several agents, including opioids, that have been employed to treat oxaliplatin-induced peripheral neuropathy (OIPN) have been examined in clinical settings regarding their protective and therapeutic effects. However, the pharmacotherapy of these agents has not yet been established. Therefore, we investigated the efficacy and tolerability of oxycodone for OIPN and subsequently with FOLFOX therapy in CRC patients.MethodsThis was a single-center retrospective study of 64 CRC patients who underwent FOLFOX therapy at the Toho University Sakura Medical Center (Sakura, Japan). Controlled-release (CR) oxycodone was concomitantly administered to 29 patients (OXY group), whereas the additional 35 patients (non-OXY group) were not given oxycodone during the FOLFOX treatment course. The incidence and severity of OIPN and the number of FOLFOX cycles were measured and compared between the two groups. Neurological toxicities were assessed according to the Common Terminology Criteria for Advanced Events, version 3.0.ResultsAll study patients had OIPN. Most patients experienced grade 1 or 2 sensory neuropathy. Grade 3 sensory neuropathy was observed in two patients in the non-OXY group. All patients in the OXY group completed the scheduled FOLFOX therapy, whereas FOLFOX therapy was discontinued in ten patients in the non-OXY group due to severe peripheral neuropathy. The median numbers of FOLFOX cycles in the OXY and non-OXY groups were 13 (range, 6–46) and 7 (range, 2–18), respectively (P < 0.05). The median cumulative oxaliplatin doses were 1072.3 mg/m2 (range, 408.7–3385.3 mg/m2) in the OXY group and 483.0 mg/m2 (range 76.2–1414.1 mg/m2) in the non-OXY group (P < 0.05).ConclusionsOur findings indicate that CR oxycodone might attenuate the severity of OIPN and extend the use of FOLFOX therapy.

A 57-year-old woman underwent modified radical mastectomy for cancer of the left breast (stage IIB) in February 2004. Invasive lobular carcinoma was diagnosed on histopathological examination. The patient received postoperative chemotherapy and endocrine therapy on an outpatient basis and was observed. In August 2005, anorexia developed. Blood chemical tests showed elevated levels of liver enzymes and bilirubin. Computed tomography (CT) of the abdomen revealed an enlarged duodenum and dilated intrahepatic biliary and pancreatic ducts. Upper gastrointestinal endoscopy showed edema of the duodenum. A biopsy yielded a diagnosis of poorly differentiated adenocarcinoma. Duodenal carcinoma was suspected, and a pancreatoduodenectomy was performed. Duodenal metastasis from invasive lobular carcinoma was diagnosed on postoperative histopathological examination. After surgery, the patient recovered uneventfully and was discharged from the hospital. In March 2006, bilateral hydronephrosis apparently caused by peritoneal metastasis developed, and she subsequently died. Invasive lobular carcinoma is characterized by the development of gastrointestinal metastases and is rarely detected before autopsy. We describe our experience with a patient in whom invasive lobular carcinoma of the breast with metastasis to the duodenal wall was definitively diagnosed on laparotomy.

SummaryPurpose Continuous treatment with FOLFOX therapy is associated with peripheral nerve toxicity, and to improve this inconvenient side effect various methods of administration are being investigated. A regimen of intermittent oxaliplatin administration by continuous infusion therapy, i.e., modified FOLFOX7 (mFOLFOX7) + bevacizumab, was designed with the goal of alleviating severe peripheral nerve disorders and hematological toxicity. A phase II clinical study was conducted to evaluate the efficacy and safety of this regimen. Methods Previously untreated patients were assigned to mFOLFOX7 (oxaliplatin 85 mg/m2, levofolinate [l-LV] 200 mg/m2, 5-fluorouracil [5-FU] 2400 mg/m2) + bevacizumab (5 mg/kg) administered every 2 weeks for 8 cycles, maintenance without oxaliplatin for 8 cycles, and reintroduction of mFOLFOX7 + bevacizumab for 8 cycles or until disease progression. Progression free survival (PFS) following the first dose (PFS 1) and following reintroduction of oxaliplatin (PFS 2) were used as indices for assessing the efficacy of intermittent administration. Results Fifty-two patients were enrolled, with median age of 64 years (range, 36–74). Median PFS 1 was 11.8 months (95 % confidence interval [CI], 9.5 to 13.7), median time to treatment failure was 10.3 months (95 % CI, 5.6 to 12.1), percentage of patients with neutropenia of grade 3 or higher was 7.8 %, and percentage with peripheral nerve disorders was 3.9 %. Response rate was 50 %, and 84.4 % of patients who started modified simplified LV5FU2 + bevacizumab were reintroduced to oxaliplatin. Conclusion By excluding 5-FU bolus administration and administering bevacizumab continuously the mFOLFOX7 + bevacizumab regimen with preplanned withdrawal of oxaliplatin showed high tolerability and prevented severe peripheral neuropathy and neutropenia without reducing efficacy.

Gastric leakage is a challenging complication of sleeve gastrectomy. Multimodal approaches, including drainage, clipping, and stenting of the leak, are occasionally insufficient. We report successful management of refractory gastric leakage using percutaneous transesophageal gastro-tubing (PTEG). Drainage and stenting proved inadequate for treating sleeve leakage near the esophagogastric junction in two patients. PTEG was finally performed, and enteral feeding was started on the following day. The patients were discharged within 1 week. The PTEG-tube was removed after confirming oral food intake. Both patients continue to do well without recurrence. PTEG was developed for patients who are unsuitable for percutaneous endoscopic gastrostomy. PTEG provides decompression and permits enteral feeding in patients refractory to other endoscopic treatments. PTEG is an option for managing intractable sleeve leakage without surgery.
