ABSTRACT

Chyloperitoneum (CP) is a rare complication after bariatric surgery. We present a 37-year-old female with CP caused by a bowel volvulus following a gastric clipping with proximal jejunal bypass for morbid obesity. An abdominal CT image of a mesenteric swirl sign and abnormal triglyceride level of ascites fluid can confirm the diagnosis. In this patient, laparoscopy demonstrated dilated lymphatic ducts caused by a bowel volvulus resulting in the exudation of chylous fluid into the peritoneal cavity. After the reduction of bowel volvulus, she made an uneventful recovery with complete resolution of the chylous ascites. The presence of CP could indicate a situation of small bowel obstruction in patients with a history of bariatric surgery.

ABSTRACT

BACKGROUND: The techniques of intracorporeal anastomosis and specimen extraction after laparoscopic colectomy via a natural orifice have gained interest increasingly. We evaluated the feasibility of our unique techniques for colorectal reconstruction and report immediate postoperative outcomes in patients with rectosigmoid cancer. METHODS: Patients with sigmoid or rectal cancer were selected depending on the size of the tumor and its distance from the anal verge. Demographic data, operative parameters, and postoperative outcomes were assessed. After complete resection of the tumor, all patients underwent an intracorporeal side-to-end colorectal anastomosis following transrectal specimen extraction. RESULTS: Laparoscopic resection with our technique of intracorporeal anastomosis was successful in 32 patients. The average operative time was 192 ± 29 min, and mean blood loss was 51 ± 18 ml. All patients experienced mild postoperative pain, and bowel function returned before postoperative day 3 in most patients. They had an uneventful postoperative course with a median hospital stay of 6 days. Major perioperative complications or anastomotic leak were not encountered in this study. The mean size of the lesion was 3.3 ± 1.8 cm, and the mean number of harvested nodes was 14 ± 6. During the follow-up period, there were no functional disorders associated with the intracorporeal anastomosis or transrectal specimen extraction. CONCLUSIONS: Intracorporeal side-to-end colorectal anastomosis with transrectal specimen extraction in laparoscopic colorectal surgery is a safe and effective procedure for patients with rectosigmoid malignancy.

ABSTRACT

Retained surgical sponge (gossypiboma) following an inguinal herniorrhaphy is a rare condition and may cause medicolegal problems. Differential diagnosis for the lesion should be made meticulously. We report a case of a 45-year-old man who had a herniorrhaphy about 8 years previously. He presented one episode of painless gross hematuria. Laboratory and imaging studies excluded any significant lesion in the urological organs. Abdominal CT scan demonstrated a heterogeneous neoplasm of 4 cm in size in the left paravesical area that was retrieved laparoscopically. Abdominal CT and clinical suspicion are helpful for diagnosis. Laparoscopy may be used to confirm the diagnosis and to remove the retained surgical gauze, and considered as an alternative therapy for some selected patients.

ABSTRACT

BACKGROUND: Despite the high cost of initial cancer care, that is, care in the first year after diagnosis, limited information is available for specific categories of cancer-related costs, especially costs for specific services. This study purposed to identify causes of change in cancer treatment costs over time and to perform trend analyses of the percentage of cancer patients who had received a specific treatment type and the mean cost of care for patients who had received that treatment. METHODOLOGY/PRINCIPAL FINDINGS: The analysis of trends in initial treatment costs focused on cancer-related surgery, chemotherapy, radiation therapy, and treatments other than active treatments. For each cancer-specific trend, slopes were calculated for regression models with 95% confidence intervals. Analyses of patients diagnosed in 2007 showed that the National Health Insurance (NHI) system paid, on average, $10,780 for initial care of a gastric cancer patient and $10,681 for initial care of a lung cancer patient, which were inflation-adjusted increases of $6,234 and $5,522, respectively, over the 1996 care costs. During the same interval, the mean NHI payment for initial care for the five specific cancers increased significantly (p<0.05). Hospitalization costs comprised the largest portion of payments for all cancers. During 1996-2007, the use of chemotherapy and radiation therapy significantly increased in all cancer types (p<0.05). In 2007, NHI payments for initial care for these five cancers exceeded $12 billion, and gastric and lung cancers accounted for the largest share. CONCLUSIONS/SIGNIFICANCE: In addition to the growing number of NHI beneficiaries with cancer, treatment costs and the percentage of patients who undergo treatment are growing. Therefore, the NHI must accurately predict the economic burden of new chemotherapy agents and radiation therapies and may need to develop programs for stratifying patients according to their potential benefit from these expensive treatments.

ABSTRACT

PURPOSE: We evaluated the safety and efficacy of biweekly capecitabine in combination with oxaliplatin in previously untreated patients with locally advanced or metastatic gastric cancer. METHODS: Patients received oral capecitabine 1,000 mg/m(2) twice daily on days 1-10 plus oxaliplatin 85 mg/m(2) as a 2-h intravenous infusion on day 1, every 2 weeks (XELOX). The primary endpoint was overall response rate. Secondary endpoints included progression-free survival, overall survival, and toxicity. RESULTS: From March 2007 to October 2010, 46 patients were enrolled in this phase II study. The median age was 64 years (range 32-85). A total of 391 (median 7.5, range 1-29) cycles were delivered. Among the 41 patients evaluable for tumor response, 9 showed partial response and 25 had stable disease. The overall response rates of the evaluable and intent-to-treat (ITT) populations were 22 % (95 % CI 10-42 %) and 20 % (95 % CI 9-34 %), respectively. In the ITT analysis, the progression-free survival and overall survival were 5.6 months (95 % CI 4.1-6.3 months) and 8.0 months (95 % CI 6.3-10.1 months), respectively. The most common hematological toxicities were thrombocytopenia (35 %) and leucopenia (34 %), whereas the most common non-hematological toxicities were neuropathy (35 %), fatigue (33 %), diarrhea (27 %), vomiting (26 %), and hand-foot syndrome (25 %). Major grade 3-4 toxicities were anemia (11 %), diarrhea (9 %), and hand-foot syndrome (7 %). No patient died of treatment-related toxicities. CONCLUSIONS: Although the biweekly XELOX regimen failed its primary response rate endpoint, it showed modest efficacy and an acceptable safety profile in the treatment of advanced gastric cancer.

ABSTRACT

Gastric cancer (GC) has a high rate of morbidity and mortality among various cancers worldwide. The development of noninvasive diagnostic methods or technologies for tracking the occurrence of GC is urgent, and searching reliable biomarkers is considered.This study intended to directly discover differential biomarkers from GC tissues by two-dimension-differential gel electrophoresis (2D-DIGE), and further validate protein expression by western blotting (WB) and immunohistochemistry (IHC).Pairs of GC tissues (gastric cancer tissues and the adjacent normal tissues) obtained from surgery was investigated for 2D-DIEG.Five proteins wereconfirmed by WB and IHC, including glucose-regulated protein 78 (GRP78), glutathione s-transferase pi (GSTpi), apolipoprotein AI (ApoAI), alpha-1 antitrypsin (A1AT) and gastrokine-1 (GKN-1). Among the results, GRP78, GSTpi and A1ATwere significantlyup-regulated and down-regulated respectively in gastric cancer patients. Moreover, GRP78 and ApoAI were correlated with A1AT for protein expressions.This study presumes these proteins could be candidates of reliable biomarkers for gastric cancer.

ABSTRACT

INTRODUCTION: Operating on an enlarged spleen via the laparoscopic approach presents several challenges. A homemade bag may facilitate retrieval of the enlarged spleen assisted by a laparoscope and save medical expense. AIM: To assess the feasibility and safety of laparoscopic splenectomy for moderate or massive splenomegaly using our technique and a homemade retrieval bag. MATERIAL AND METHODS: Fifty patients underwent laparoscopic splenectomy for moderate or massive splenomegaly which was defined as the major axis exceeding 17 cm by abdominal computed tomography. A homemade retrieval bag made from a commercial sterile infusion container which costs about US$ 1-2 per piece was used for spleen retrieval. Two transabdominal sutures for suspension of the retrieval bag were made to aid specimen removal in this technique. RESULTS: There were 31 males and 19 females with mean age of 56 ±11 years. Laparoscopic splenectomy was successfully completed in 49 of these 50 patients. Overall, mean operative time was 149 ±31 min (range: 100-252 min). Median estimated blood loss was 189 ±155 ml (range: 50-920 ml). There were 12 minor complications but no mortality. Time to discharge after surgery ranged from 3 to 9 (mean: 4.7 ±1.7 days). The average splenic weight was 729 ±74 g (range: 632-930 g). CONCLUSIONS: Our preliminary results indicate that laparoscopic splenectomy is feasible and safe for moderate or massive splenomegaly and may be a well-tolerated alternative to open splenectomy. Not only is the cost of our homemade retrieval bag low, but also it is easy to make and ready to use.

ABSTRACT

PURPOSE: We aimed to evaluate the feasibility of staged laparoscopic colectomy for acute malignant colon obstruction. METHODS: Through a laparoscopic approach, emergency blowhole colostomy and subsequent elective resection were performed. RESULTS: There were 14 men and 8 women, ages ranging from 42 to 79 years. All patients underwent laparoscopic blowhole colostomy for fecal diversion. Of these stomas, 6 were located at the splenic flexure, 7 at the descending colon, and 9 at the sigmoid colon. Subsequently, 20 of the 22 patients achieved an elective laparoscopic resection including takedown of the stoma. They were left hemicolectomy in 11 and anterior resection in 9. The mean total length of hospital stay was 20 ± 4.6 days (range, 16 to 33 d) in these 20 patients. The remaining 2 patients did not undergo reversal of the colostomy. The median follow-up period was 23 months. Seven patients died of disease progression and 15 patients remained alive and well. CONCLUSIONS: Our results suggest that staged laparoscopic colon resection is a feasible and effective technique for acute malignant colonic obstruction. The length of hospital stay is justified as compared with conventional single-staged resection. Our technique can also be recommended when colonic stenting is not available.

ABSTRACT

BACKGROUND: The identification of KRAS, BRAF, and PIK3CA mutations before the administration of anti-epidermal growth factor receptor therapy of colorectal cancer has become important. The aim of the present study was to investigate the occurrence of KRAS, BRAF, and PIK3CA mutations in the Taiwanese population with colorectal cancer. This study was undertaken to identify BRAF and PIK3CA mutations in patients with colorectal cancer by high-resolution melting (HRM) analysis. HRM analysis is a new gene scan tool that quickly performs the PCR and identifies sequence alterations without requiring post-PCR treatment. METHODS: In the present study, DNAs were extracted from 182 cases of formalin-fixed, paraffin-embedded (FFPE) colorectal cancer samples for clinical KRAS mutational analysis by direct sequencing. All the samples were also tested for mutations within BRAF V600E and PIK3CA (exons 9 and 20) by HRM analysis. RESULTS: The results were confirmed by direct sequencing. The frequency of BRAF and PIK3CA mutations is 1.1%, and 7.1%, respectively. Intriguingly, we found that nine patients (4.9%) with the KRAS mutation were coexistent with the PIK3CA mutation. Four patients (2.2%) without the KRAS mutation were existent with the PIK3CA mutation. Two patients (1.1%) without the KRAS mutation were existent with the BRAF mutation. CONCLUSIONS: In the current study, we suppose that HRM analysis is rapid, feasible, and powerful diagnostic tool for the detection of BRAF and PIK3CA mutations in a clinical setting. Additionally, our results indicated the prevalence of KRAS, BRAF, and PIK3CA mutational status in the Taiwanese population.

ABSTRACT

The objective of this study is to explore the inflammatory modulation effect of glutamine-enriched total parenteral nutrition (TPN) by investigating the alterations of inflammation-related cytokines in gastrointestinal (GI) cancer patients postoperatively. Fifty GI cancer patients received postoperative 7 days of isocaloric and isonitrogenous TPN after operation. They were randomly divided to receive either glutamine-enriched TPN or standard TPN. The inflammation-related cytokines including interleukin-6, interleukin-10, and tumor necrosis factor-α were also determined. Records of nutritional assessments, inflammatory status, and postoperative complications were compared between the two groups. Of 50 enrolled patients, 25 patients were classified as the intervention group, and the control group also comprised 25 patients. The differences of gender, age, primary GI malignancies, and hematological and biochemical data between the two compared groups were not statistically significant (all P > 0.05). Compared with standard TPN, a higher serum prealbumin level and better nitrogen balance were observed in glutamine-enriched TPN (P = 0.039 and 0.048 respectively). A significantly lower serum interleukin-6 level was found in comparing glutamine-enriched with standard TPN (P = 0.01), but not in interleukin-10 (P = 0.374) and tumor necrosis factor-α levels (P = 0.653). Moreover, a significant lower serum C-reactive protein level was detected in glutamine-enriched TPN compared with standard TPN (P = 0.013). Indeed, four cases of postoperative infectious complications were noted in the control group, but no postoperative infectious complications were observed in the interventional group (P = 0.037). Our present study shows that glutamine-enriched TPN may be beneficial in improving the inflammatory status and decreasing the infectious morbidity in postoperative GI cancer patients.

ABSTRACT

BACKGROUND: Metachronous liver metastasis (MLM) occurs in 20-40% of colorectal cancer (CRC) patients following surgical treatment. The aim of the present study was to determine the risk factors affecting the development of MLM in CRC patients following curative resection. METHODS: A total of 1,356 patients who underwent curative intent resection for CRC were retrospectively studied. Of these patients, those who with 30 days postoperative mortality (n=23), incomplete medical record (n=32), synchronous liver metastasis (n=148) and UICC stage IV (n=54) were excluded, and finally 1,099 patients were analyzed, including 977 patients without liver metastasis and 122 patients with MLM-only. Clinical and pathological records for each patient were reviewed from medical charts. The clinicopathologic characteristics of 1,099 patients were investigated. RESULTS: The median timing of developing MLM was 13 months with a range of 4 to 79 months. Univariate analysis identified that preoperative serum carcinoembryonic antigen (CEA) level, depth of invasion, lymph nodes metastasis, vascular invasion, and perineural invasion were significantly correlated with the development of MLM (all P<0.05). Meanwhile, a multivariate analysis showed that preoperative serum carcinoembryonic antigen (CEA) level>5 ng/ml (Odds Ratio [OR]=1.591; 95% Confidence Interval [CI], 1.065-2.377; P=0.024), tumor depth (OR=2.294; 95% CI, 1.103-4.768; P=0.026), positive lymph node metastasis (OR=2.004; 95% CI, 1.324-3.031; P=0.001) and positive vascular invasion (OR=1.872; 95% CI, 1.225-2.861; P=0.004) were independent prognostic factors contributing to the occurrence of MLM. CONCLUSIONS: The present study demonstrates that preoperative serum CEA level, tumor depth, lymph node metastasis, and positive vascular invasion could affect the occurrence of MLM in CRC patients following curative resection, and thus could help to define these high-risk patients who would benefit from enhanced surveillance and therapeutic program(s).

ABSTRACT

AIM: To investigate the use of lipid emulsion substituting for glucose in postoperative hypocaloric peripheral parenteral nutrition (HPPN). METHODS: This prospective, randomized study was conducted on 20 postoperative gastrointestinal cancer patients. They were randomized and equally divided into interventional group and control group, and both were administered isocaloric and isonitrogenous diets with for lipid emulsion substituting for partial glucose loads in the interventional group. RESULTS: Nutritional parameters and biochemical data were compared between the two groups before and after 6-d of HPPN. Most investigated variables showed no significant changes after administration of HPPN with lipid emulsion. However, the postoperative triglyceride level was significantly lower in the interventional group than in the control group (P < 0.05). In comparison with lipid emulsion, glucose administration resulted in less decrease in postoperative prealbumin level (P < 0.05). CONCLUSION: In addition to supplementing with essential fatty acid, it seems that HPPN with lipid emulsion is well-tolerated and beneficial to postoperative gastrointestinal cancer patients.

ABSTRACT

This report describes a patient with a gastrointestinal stromal tumor (GIST) and upper gastrointestinal hemorrhage as initial presentations of the Carney triad, a synchronous or metachronous condition involving gastric leiomyosarcoma, extra-adrenal paraganglioma and pulmonary chondroma. A 26-year-old woman presented with dizziness and several episodes of melena over 3 days. Physical examination revealed pale conjunctiva but normal hemodynamic status. Gastroendoscopy showed one antral submucosal tumor with evidence of an associated bleeder (the bleeder over the mucosal surface of the gastric tumor). An abdominal computed tomography scan showed an antral submucosal tumor, two secondary lesions over segment II/V of the liver and a retroperitoneal tumor. Surgical removal of the tumor and subsequent recovery were uneventful. The gastric GIST with liver metastasis and retroperitoneal paraganglioma were confirmed by pathologic study. The patient was treated with imatinib mesylate for the GIST with liver metastasis, and continued follow-up treatment at our hospital. An abdominal computed tomography scan at 32 months after surgery showed no change in the liver metastatic lesions and no evidence of local recurrence. Another follow-up visit at 33 months after surgery confirmed the stable condition. Of nearly 100 cases reported in the literature, this case is the first to be reported in Taiwan. This case highlights the possibility of this rare syndrome occurring in young female patients with one of the three components of the triad and the need for further diagnostic studies for early identification of tumors when curative surgery is still possible.

ABSTRACT

Glomus tumors are usually thought of as benign tumors although some malignant cases have been reported. These tumors arise from the glomus body and are commonly observed in the dermis or subcutis, but rarely in visceral organs. Here, we report a 37-year-old female who initially presented with epigastric discomfort. The preoperative diagnosis was a gastrointestinal stromal tumor. A minilaparotomy was done with an incision length of 4 cm followed by wedge resection. The final pathologic diagnosis was a gastric glomus tumor. We have reviewed the only five cases of gastric glomus tumors that have been reported to date in Taiwan, including the present case, and compare these cases with those reported in other countries. The age of onset ranged from 35 to 69 years (median, 41 years) with female dominance (4 females and 1 male). Two of the five cases presented with gastrointestinal bleeding with an ulcerative tumor, and the others only had epigastric discomfort. The tumors were located around the prepyloric antrum of the stomach. No definite diagnosis was reached before surgery in any of the five cases, and all of the tumors were considered likely to be benign lesions. Clinicians who treat such patients should be aware of this problem because of the difficulty in accurate preoperative diagnosis.
