RESUMEN
Ureterosciatic hernia is a rare urological entity. We report a case of successful laparoscopic surgery for a ureterosciatic hernia that recurred repeatedly after conservative treatment. A 73-year-old woman complained of left abdominal pain. Computed tomography (CT) showed a left ureterosciatic hernia. After placement of the ureteral stent, the ureterosciatic hernia improved. The ureteral stent was removed after ureteral migration became normal. Four years and 8 months later, left ureterosciatic hernia recurred. Same treatment was performed; however, it recurred again. Therefore, laparoscopic surgery using a mesh was performed. The patient had no recurrence 9 months postoperatively.
RESUMEN
The prognosis of patients with scirrhous gastric cancer (SGC) is extremely poor. However, recent advances in therapeutic strategies against SGC, using effective anticancer drugs, have prolonged the survival of patients with SGC. This paper reviews the recent therapeutic outcomes of this type of gastric cancer and introduces a new treatment protocol for SGC.

Locally advanced carcinomas arising in the hypopharynx, cervical esophagus, or thyroid are traditionally treated by resection of the hypopharynx and cervical esophagus. Various methods of reconstruction aiming to achieve safety and functionality have been reported, including the myocutaneous flap and the free jejunal graft. With advances in microscopic surgery, the free jejunal transplant is now used dominantly; however, this procedure is not without major risks. In this review we examine the short- and long-term complications of this procedure. We also describe our technique of free jejunal graft reconstruction after pharyngoesophagectomy and total laryngectomy with definitive tracheostomy. We used free jejunal graft reconstruction after resection with hypopharyngeal cancer or thyroid cancers in 22 patients. Twenty-one of these patients acquired a good quality of life, but one died after loss of the jejunal graft. Thus, using a free jejunal graft for reconstruction of the hypopharynx or cervical esophagus can be very useful in improving the quality of life of patients.

Optimal treatment of patients with gastric cancer with synchronous distant metastases is palliative chemotherapy. However, occasionally gastrectomy should be selected due to control bleeding from tumors, perforation, or obstruction. The aim of this study is to evaluate the survival benefits of non-curative gastrectomy for patients with synchronous distant metastasis. Total 78 gastric cancer patients with synchronous distant metastasis treated in our hospital between 2003 and 2012 were enrolled in this study. Of these, 74 patients (95 %) received S1 based chemotherapy. During the treatment, 37 patients (47.4 %) underwent palliative gastrectomy because of bleeding from tumors (n = 15), tumor perforation (n = 6), and obstruction (n = 16). Survival benefits were compared in resected and non-resected patients, retrospectively. The two groups were clinicopathologically similar. Palliative gastrectomy was performed safely (morbidity: 10.8 % and mortality: 0) in resection group. However, resection showed survival benefits only in 13 patients (16.7 %) with single metastasis and without peritoneal metastasis. Their 2-year survival rate was 40 % and their median survival was 19 months. Non-curative gastrectomy with precise surgical techniques followed careful postoperative nutrition management may improve survival only for patients with a single metastatic site, except for peritoneal dissemination.
RESUMEN
BACKGROUND: Laparoscopic surgery requires a more detailed understanding of local anatomy than does conventional open surgery. The aim of this study was to examine the usefulness of dynamic computed tomography (D-CT) for identification of the location of the left gastric vein (LGV) and existence of the aberrant left hepatic artery (ALHA) compared with conventional enhanced computed tomography (E-CT). METHODS: Sixty-eight patients underwent laparoscopic-assisted gastrectomy (LAG). E-CT and D-CT were performed in 32 and 36 patients, respectively, and three-dimensional computed tomographic angiography (3D-CTA) was performed in addition to D-CT. The location of the LGV and existence of the ALHA were confirmed during LAG, and these results were compared with those determined preoperatively by CT imaging. RESULTS: The location of the LGV as detected by preoperative E-CT and D-CT was consistent with that identified during LAG in 28 (87.5%) and 31 (88.9%) patients, respectively, with no statistical differences. The existence of the ALHA as detected by preoperative E-CT and D-CT was consistent with that identified during gastrectomy in 24 (75%) and 36 (100%) patients, respectively, with a statistical difference (P = 0.005). Furthermore, the type of ALHA could be identified in 10 of 12 patients (83.3%) by D-CT. CONCLUSION: D-CT can produce excellent images of the vascular supply, and thus undoubtedly contributes to the preoperative planning of LAG. Preoperative D-CT might be an informative tool with which to help overcome the disadvantages of LAG.
RESUMEN
PURPOSE: Treatment of patients with stage IV gastric cancer is controversial. This study was retrospectively designed to elucidate the best treatment for these patients. METHODS: Between 2003 and 2010, a total of 558 patients with gastric cancer were treated at the Department of Surgery, Tottori University Hospital, 96 (17.2 %) of whom were diagnosed with stage IV. Among 96, 54 underwent palliative gastrectomy while 42 underwent chemotherapy, exploratory laparotomy, or gastrojejunostomy for unresectable cases. Surgical morbidity, mortality, and patient survival were analyzed with respect to several factors. RESULTS: Among resected cases, high age, R2 operation, and neoadjuvant chemotherapy did not increase the occurrence of postoperative complications. Patient age, R1 operation, and sufficient chemotherapy were indicated as better prognostic factors for resected stage IV gastric cancers. Even after R2 operation, continuous chemotherapy with changing regimens prolonged R2 resected patients' survival to 25 months (mean). In unresectable cases, bypass operation did not affect patients' survival. But, chemotherapy with changing regimens prolonged the survival of unresectable cases. CONCLUSIONS: Adequate management can resolve surgery-related morbidity, and continuous chemotherapy may be one of the most important prognostic factors in stage IV gastric cancer.

The aim of this study was to evaluate the clinical usefulness of the palliative prognostic (PaP) score in patients with non-resectable advanced gastric cancer. The PaP score was calculated prior to each course of chemotherapy in 44 consecutive patients with non-resectable advanced gastric cancer between 2003 and 2010 at the Tottori University Hospital, Yonago, Japan. The prognosis was evaluated according to the PaP score and the different chemotherapeutic agents. The median survival time (MST) was 10 months. The PaP score classified the heterogeneous patient sample into three isoprognostic groups with regard to the possibility of a 1-month survival period, with 28 patients in group A (>70% chance), 12 in group B (30-70% chance) and 4 in group C (<30% chance). The MST of the three groups was 11, 3 and 1 months for group A, B and C, respectively. In group A, chemotherapeutic regimens did not affect patient survival, although the docetaxel regimen prolonged survival of patients in group B. In conclusion, the PaP score may be useful in selecting the best chemotherapeutic regimen in patients with non-resectable gastric cancer.
RESUMEN
Proximal gastrectomy (PG) has been introduced for patients who are preoperatively diagnosed with early gastric cancer located in the upper third of the stomach. In the present study, we compared the prognosis of patients who underwent PG with that of patients who underwent total gastrectomy (TG). Between 1997 and 2006, 51 patients were diagnosed with early gastric cancer located in the upper third of the stomach and underwent PG. In the same period, 35 patients were diagnosed with early gastric cancer and underwent TG. Of these, in 24 patients, the cancer was localized in the middle to upper part of the stomach, and 11 patients had multiple cancers. We compared the clinicopathologic differences and prognoses between the two groups. Significantly fewer lymph nodes were dissected in the PG group (mean, 18.2) than in the TG group (mean, 36.6;P < 0.001). Complications were detected in 17.6% of patients in the PG group and in 14.3% of patients in the TG group, which was not significant (P = 0.678). The overall and disease-specific 5-year survival rates in the 51 patients who underwent PG (88.7% and 97.1%, respectively) were not different from those in the 35 patients who underwent TG (87.6% and 93.4%; P = 0.971 and P = 0.553; respectively). These findings indicate that PG can be performed safely and may have various advantages compared with TG in terms of patients' daily lives.

BACKGROUND: Interleukin-6 (IL-6) is known to be a multifunctional cytokine and IL-10 is an immunosuppressive factor. Both have been reported to be related to the disease prognosis in some human solid tumors. In the present study, we evaluated the clinical significance of preoperative serum IL-6 and IL-10 levels as new tumor markers in patients with gastric cancer (GC). METHODS: Preoperative serum samples from 90 patients with GC and 9 normal healthy volunteers were assayed. Levels of IL-6 and IL-10 were determined by enzyme-linked immunosorbent assay (ELISA). The clinical significance of serum IL-6 and IL-10 levels was evaluated and compared with serum carcinoembryonic antigen (CEA) levels and serum C-reactive protein (CRP) levels in these patients. RESULTS: The serum level of IL-6 was significantly higher in the GC patients than in the healthy subjects. Serum IL-6 levels were strongly correlated with CRP levels, but did not correlate with CEA or carbohydrate antigen (CA) 19-9 levels. Serum IL-10 levels did not correlate with CEA, CA19-9, or CRP. Strong positive correlations between serum IL-6 levels and tumor size and tumor stage were observed. On the other hand, IL-10 did not correlate with such clinicopathological findings of tumors. However, high serum IL-10 levels were associated with a worse prognosis in the GC patients, independently of their tumor stage. CONCLUSION: These findings indicate that serum IL-6 may suggest gastric cancer progression. On the other hand, IL-10 may play an important role in host immunity and the prognosis of GC patients.

BACKGROUND: Carcinoma arising in the cardioesophageal junction is a distinct clinical entity compared with tumors located in other regions of the stomach. The prognosis for adenocarcinoma of the upper stomach is considered to be relatively poorer than carcinomas of the more distal stomach. We have therefore investigated patients with carcinoma of the gastric cardia in order to evaluate the underlying cause of this poor prognosis. MATERIALS AND METHODS: Clinicopathologic features and postoperative prognosis of 101 patients with carcinoma of the cardia were evaluated and compared with findings on 1884 patients with tumors in other regions of the stomach. RESULTS: Tumors of the cardia had a mean size of 6.8 cm, which was significantly larger than the mean size of 5.9 cm for tumors found in the middle- and lower third of the stomach. The incidence of serosal invasion, lymph node metastasis, and lymphatic and blood vessel invasion was higher in association with adenocarcinoma of the cardia than with adenocarcinoma in remaining parts of the stomach. In the analysis of patients who had undergone curative resection, the 5-year survival rates were 61.6, 79.1, and 82.6% in patients with carcinoma of the cardia, upper one-third, and remaining middle- and lower one-third of the stomach, respectively, and the differences were statistically significant. Multivariate analysis indicated that adenocarcinoma of the gastric cardia is an independent prognostic factor. With regard to the site of recurrence, both lymph node and hematogenous recurrence were observed more frequently in the cardia than in the remaining parts of the stomach. CONCLUSIONS: Our data indicate that the prognosis of patients with adenocarcinoma of the gastric cardia is extremely poor. To improve their prognosis, new treatments in addition to gastrectomy with extensive lymph node dissection are needed.

BACKGROUND: The gene expression of the cytokines interleukin-2 (IL-2) and IL-10 in peritoneal washings was examined in relation to the presence of cancer cells in the peritoneal cavity in patients with gastric cancer. METHODS: Total RNA was extracted from 50-ml peritoneal wash samples from 124 patients (gastric cancer, n = 110; controls, n = 14). Carcinoembrionic antigen (CEA) messenger RNA (mRNA) was used to identify the number of cancer cells in peritoneal wash samples by a real-time reverse transcription-polymerase chain reaction (RT-PCR) method, which method was also used to assay the IL-2 and IL-10 gene expression levels. RESULTS: In the 14 control samples, CEA mRNA was not detected, while CEA mRNA was detected in 2 of the 51 stage I gastric cancer patients. Thus, the specificity of this method for the detection of cancer cells in peritoneal wash samples was 97% (63/65). The CEA-based real-time RT-PCR method demonstrated greater prognostic impact than the traditional cytological method. IL-2 gene expression in peritoneal wash samples that were CEA mRNA-positive was suppressed compared with that in peritoneal wash samples that were CEA mRNA-negative, while IL-10 gene expression did not differ according to the CEA mRNA findings. CONCLUSION: The detection of small numbers of cancer cells in peritoneal wash samples from patients with advanced gastric cancer is a good marker for peritoneal metastatic recurrence. In the peritoneal cavity, cancer cells may escape from immune surveillance by controlling the expression of cytokines.
