RESUMEN
Since the insurance coverage of colorectal stents for bowel obstruction due to colorectal cancer in 2012, the use of colorectal stenting for palliation has rapidly spread. We report a case of ascending colon cancer in which a colorectal stent was placed for palliation, but the stent was reimplanted due to obstruction, followed by radical resection. The patient was a 92- year-old woman who was brought to the emergency room at the age of 90 years with repeated vomiting and abdominal pain, and was diagnosed as colorectal cancer ileus caused by ascending colon cancer, and a colorectal stent was inserted. She received palliative care and had been asymptomatic for 1 year and 3 months, but due to in-stent stenosis, she had bowel obstruction and sent to emergency room, and another stent was installed. The patient had a good course, but 4 months after the second stenting, she was concerned about restenosis and referred to the department of surgery, then performed a radical resection. The indication for colorectal stents for palliative purposes should be considered on a case-by- case basis, including ADL, stage of the disease, and prognosis.

Solitary colonic metastasis from esophageal cancer is rare. The prognosis of patients with distant metastases from esophageal cancer is extremely poor. A case of long-term survival with colonic metastasis from esophageal cancer treated by multimodal therapy is reported. A 67-year-old man was diagnosed with middle thoracic esophageal squamous cell carcinoma. The patient received neoadjuvant chemotherapy and then underwent subtotal esophagectomy. Approximately 1 year after esophagectomy, an asymptomatic, solitary colonic mass was detected on the follow-up computed tomography for esophageal cancer. Preoperative colonoscopy showed a 5-cm type 3 tumor at the ascending colon, and histological findings of the biopsy specimen indicated possible metastasis from primary esophageal squamous cell carcinoma. The patient underwent laparoscopic ileocolic resection with D3 lymph noddle dissection. Histologically, the colonic tumor was confirmed to be a metastasis from the esophageal squamous cell carcinoma. To the best of our knowledge, only eight cases with resected solitary colonic metastasis, including the present case, have been reported, and the present patient achieved greater than 3-year survival after esophagectomy. Resection of an asymptomatic solitary organ metastasis from primary esophageal cancer appears to be a good therapeutic option, even following esophagectomy.

A 69-year-old man with dysphagia was diagnosed with advanced esophageal cancer by upper gastrointestinal endoscopy. He had undergone pancreatic tail and partial transverse colon resection for pancreatic cancer, and right hilar lymph node biopsy and partial lower lobe resection for the diagnosis of pulmonary sarcoidosis. Contrast-enhanced computed tomography(CT)scan showed no change over time in lymph node enlargement in the mediastinum, so metastasis of esophageal cancer was considered to be negative. Therefore, the diagnosis of advanced esophageal cancer, Mt, type 2, T2N0M0, cStage â ¡, was made, and surgery was performed after 2 courses of DCF therapy. Because of the adhesions in the thoracic cavity and possible problems with elevation of the gastric tube and blood flow due to resection of the pancreatic tail, it was decided to perform two-stage operation. Although imaging studies over time, as in the present case, can help in the diagnosis, it is difficult to distinguish whether enlarged lymph nodes are reactive changes or metastases. In this study, we experienced a case of thoracic esophageal cancer complicated by sarcoidosis with enlarged mediastinal lymph nodes.

An 84-year-old man with gastric cancer, cT2N0M0, cStage â underwent laparoscopic distal gastrectomy, D1+dissection, and Roux-en-Y reconstruction. We started enteral nutrition on the second postoperative day, but milky drainage appeared from the drain on the fifth postoperative day. The triglyceride in the ascites was markedly elevated, and it was diagnosed as a lymphorrhea. Neither conservative treatment nor lymphangiography were successful. We decided to perform surgical intervention because the lymphorrhea did not improve for about 1 month after gastrectomy. At laparotomy, we detected the lymphatic ducts using enteral nutrition of fat formulas during surgery and successfully closed the lymphatic ducts by suturing and ligation on the 38th postoperative day. Prolonged lymphorrhea causes extreme deterioration of the patient's general condition. Prolonged total parenteral nutrition also increases the risk of infection. It is important to perform surgical treatment for intractable lymphorrhea that does not improve with conservative treatment without hesitation.

Primary esophageal liposarcoma is an extremely rare malignancy, whereas liposarcoma is one of the most common soft tissue sarcomas, which develop mainly in the soft tissues of the extremities and retroperitoneum. A rare case of giant esophageal liposarcoma that originated from the cervical esophagus that was successfully excised by a cervical approach is reported. A 72-year-old woman presented with difficulty swallowing for 6 months. Esophagogastroduodenoscopy showed a pedunculated esophageal submucosal tumor arising just below the pyriform fossa in the esophagus. Contrast-enhanced computed tomography showed a giant, heterogeneous, intraluminal esophageal tumor from the cervical esophagus to the upper thoracic esophagus for approximately 17 cm. Based on the imaging findings, an esophageal liposarcoma was suspected. Since the symptom of dysphagia was gradually worsening, surgical treatment was planned. The giant esophageal tumor was successful resected through a cervical approach without either thoracotomy or laparotomy. The patient's postoperative course was uneventful, and she was discharged on day 15 after surgery. The histopathological and immunohistological findings showed well-differentiated esophageal liposarcoma, 15 × 7 × 5 cm in size. A cervical approach is an appropriate option for a tumor that developed at the cervical esophagus as a minimally invasive surgical technique.

A 78-year-female underwent distal gastrectomy for gastric cancer. The final diagnosis was moderately differentiated tubular adenocarcinoma, T4a, N2, M0, Stage â ¢B. Four years later, S6 hepatic metastasis and S9 pulmonary metastasis were detected. After 10 courses of S-1 plus oxaliplatin therapy, she received partial hepatectomy(S6). One year after hepatectomy, she underwent partial pulmonary resection for lung metastasis in the left lung(S9). Histopathological findings revealed the lung tumor was a pulmonary metastasis from gastric cancer with a small primary lung adenocarcinoma. There has been no recurrence for 30 months since the last operation.

A 71-year-old man with pathological Stage â (pT1bN0M0)underwent laparoscopic sigmoid colon cancer resection. After 18 months postoperatively, follow-up computed tomography(CT)showed a 30 mm enhanced soft tissue tumor near the anastomotic site. Considering the magnetic resonance imaging(MRI)and positron emission tomography(PET)results, we diagnosed sigmoid colon cancer with local recurrence. Laparoscopic radical resection of the colon and intestine, including the tumor, was performed. Pathologically, the tumor comprised spindle-shaped cells with collagen fibers and was diagnosed as a desmoid tumor by immunostaining(ß-catenin+, c-kit-, CD34-, α-SMA-, and DOG-1-). We report a case of intra-abdominal desmoid tumor near the anastomotic site after laparoscopic sigmoid colon cancer resection.

BACKGROUND: Advanced gastric cancer with peritoneal dissemination is difficult to treat, although prognosis has improved with chemotherapy and the introduction of molecular targeted drugs. CASE: A 65-year-old male was diagnosed as type 3 advanced gastric cancer on the posterior wall of antrum by esophagogastroduodenoscopy for anemia screening. When the patient underwent radical surgery, multiple disseminated nodules(P1c)were detected. After chemotherapy(SOX, PTX plus RAM)was administered, the tumor shrank, and staging laparoscopy was performed. Since disseminated nodules have disappeared, distal gastrectomy(R0)was performed as conversion surgery. As postoperative adjuvant chemotherapy, S-1 was administered for about 1 year and 6 months. During repair of incisional hernia at 1 year postoperatively, the patient was confirmed to have no disseminated recurrence. The patient is currently alive with no sign of recurrence for 4 years.

A 69-year-old man presented to our hospital with chief complaints of epigastral pain and nausea, was diagnosed with intestinal obstruction after gastric surgery. Abdominal CT performed on the admission showed the tumor located on the terminal ileum. On colonoscopy, type 1 cancer was found near the Bauhin valve in the ileum, and suspected primary ileal carcinoma. Laparoscopic ileocecal resection was performed. The pathological diagnosis was moderately differentiated adenocarcinoma, and the pathological stage was T3(SS), N1(3/16), M0, Stage â ¢A. Although superficial surgical site infection was occurred, the patient was discharged 11 days after surgery. He hoped to adopt without adjuvant chemotherapy, so he has been followed as outpatient. Twenty one months since the surgery, there has been no evidence of cancer recurrence.

Most cases of adult intussusception are caused by neoplastic lesions, and idiopathic adult intussusception is very rare. We present a case in which laparoscopic surgery was performed for idiopathic adult intussusception initially reduced by colonoscopy. A 53-year-old woman presented to the emergency department of our hospital with intermittent lower abdominal pain. Contrast-enhanced computed tomography and ultrasonography of the abdomen showed a concentric structure in the ascending colon. We diagnosed intussusception. Colonoscopy achieved successful reduction before surgery. Twelve days after this reduction, laparoscopic surgery was performed. Histopathological examination did not reveal any causative pathology; therefore, idiopathic adult intussusception was diagnosed. The postoperative course was uneventful, and the patient was discharged on postoperative day 14. Preoperative colonoscopy should be utilized to diagnose the main lesion and may be useful for reducing adult intussusception. Laparoscopic surgery is both minimally invasive and safe and can be performed following endoscopic reduction.
RESUMEN
AIMS: The reflux of duodeno-gastric contents into the remnant esophagus (gastric tube-esophageal reflux: GTER) is a significant issues in long-term esophageal cancer survivors after radical esophagectomy. We attempted endoscopic valve (funnel) creation for prevention for GTER using OverStitch endoscopic suturing system. METHODS: The OverStitch was mounted onto a standard double-channel endoscope. Under general anesthesia, the funnel creation was attempted by placing semi-full thickness sutures on the gastric wall, at 3 cm distal to the primary esophago-gastric anastomosis. The postoperative outcomes were also evaluated. RESULTS: In total, 4 sutures were needed and the operating time was 62 minutes without complication. The endoscopic and swallowing studies, as well as pH profile, were all improved postoperatively. The patient's quality of life was dramatically improved with complete disappearance of night-time reflux in spine position. CONCLUSIONS: Endoscopic antireflux funnel creation was feasible and safe. This procedure may become a useful treatment for patients with severe GTER after esophagectomy.
RESUMEN
BACKGROUND: Intestinal ischemia can lead to fatal complications if left unrecognized during surgery. The current techniques of intraoperative microvascular assessment remain subjective. Probe-based confocal laser endomicroscopy (pCLE) has the potential to objectively evaluate microvascular blood flow in real-time setting. The present study evaluated the technical feasibility of real-time intestinal bloodstream evaluation using pCLE in a porcine intestinal ischemia model. METHODS: Seven pigs were used. The intestinal ischemia model was prepared by sequentially dividing the mesenteric blood vessels. The intestinal bloodstream was evaluated on its serosal surface using pCLE (Cellvizio 488 probe, Ultra Mini O) at every 1-cm segment from a vessel-preservation border (i.e., the cut end of the vessel). Images of the blood vessels and flow of red blood cells (RBCs) in each visualized vessel were semi-qualitatively assessed using a 3-scale scoring system. In addition, 25 surgeons blindly assessed the 10 movies recorded at 0, 1, 2, 3, and 5 cm from a vessel-preservation border using a 4-scale scoring system to confirm the consistency of the evaluation of the pCLE system. RESULTS: Images of the blood vessels were successfully obtained from the cut end of the vessel to the segment 4 cm away. Good unidirectional flow of RBCs was observed from the cut end to the 2-cm segment, whereas the flow became bidirectional between 2 and 3 cm segments. Beyond 4 cm, no flow images were obtained. The specimen obtained from the segment beyond 4 cm showed remarkable mucosal color change, which was confirmed as a necrotic change histologically. The evaluations from the cut end of the vessel to the segment 1 cm away by surgeons were excellent or good and it was almost consistent. CONCLUSIONS: Real-time bloodstream evaluation using pCLE is feasible and potentially effective for predicting intestinal ischemia during surgery.

BACKGROUND: Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. CASE PRESENTATION: A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg2 cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. CONCLUSIONS: The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.
RESUMEN
INTRODUCTION: Large esophageal hiatal hernias occur most commonly in elderly patients with comorbidities, in whom even an elective surgery cannot be performed without high risks. Although fundoplication is recommended for esophageal hiatal hernia repair, we prefer not to limit our options to fundoplication, as obstruction is a frequent main complaint. We favor an anterior gastropexy approach instead to perform anti-reflux surgery and prevent recurrent protrusion and torsion of the incarcerated organ with minimal risk. The aim was to evaluate the safety and effectiveness of anterior gastropexy for large hiatal hernia in elderly patients with comorbidities. CASE PRESENTATION: We retrospectively evaluated 8 patients who underwent laparoscopic anterior gastropexy for large hiatal hernia (type III or IV) since 2006. All patients were women with a median age of 82 years (range, 74-87 years). The major complaint was obstruction in all patients, with relatively mild reflux symptoms. They underwent successful laparoscopic surgery with no conversion to laparotomy. Fundoplication was performed in 4 cases. No perioperative complications occurred, and the main complaint resumed rapidly in all patients, without recurrence during postoperative follow-up of median 48 months (range, 5-77 months). CONCLUSION: Laparoscopic anterior gastropexy is safe and effective and can be considered as one of the practical surgical options for large hiatal hernias in elderly patients, whom surgical intervention should be minimized due to their comorbidities.
RESUMEN
Background and study aims: Gastric reflux into the remnant esophagus after subtotal or partial esophagectomy is associated with impairment in patient quality of life. We evaluated the feasibility, safety, and potential effectiveness of a novel procedure using a new endoscopic suturing device to create an anti-reflux valve (funnel) in pigs after esophagectomy with gastric tube reconstruction. Methods: The endoscopic procedure was performed in four pigs using a semi-full-thickness endoscopic suturing system (OverStitch; Apollo Endosurgery, Austin, Texas, USA). The operating time, funnel height, ratio of the height of the funnel to the diameter of the gastric tube, and adverse events associated with the procedure were evaluated. The "reflux angle" was measured morphologically and functionally during a reflux induction test, using contrast medium or artificial gastric fluid, by tilting the operating table gradually from a head up to a head down position. Reflux angles before and after funnel creation were compared. Results: The procedure was successful in all four animals. The median operating time was 43 minutes, and the median funnel height was 17âmm (56.7â% of gastric tube diameter). There were no adverse events associated with the procedure. The reflux angle was lower after the procedure compared with before in both morphological and functional assessments in all four cases. Conclusions: Endoscopic anti-reflux funnel creation using OverStitch was feasible, safe, and potentially effective.

BACKGROUND: In digestive cancers, it is mandatory to diagnose peritoneal metastasis prior to selecting therapy. Therefore, exploratory laparoscopy has gained wider clinical acceptance. In laparoscopy, the peritoneal metastasis is pathologically confirmed by excisional biopsy; however, there remain technical difficulties in performing precise diagnosis and adequate biopsy on small peritoneal lesions without damaging organs. We have focused on "optical biopsy" using probe-based confocal laser endomicroscopy (pCLE). The aims of this study were (1) to optimize current CLE system for real-time observation of peritoneal metastases and (2) to assess its potential usefulness as diagnostic modality in preclinical settings. METHODS: To optimize condition and evaluate feasibility, we prepared peritoneal metastasis mice model with gastric cancer cell line (MKN-45). On Day 10 after seeding, the mice were laparotomized and performed pCLE observations with CellvizioLAB (LSU-F 400/488 nm, Mauna Kea Technologies, Paris, France). We evaluated two different CLE probes, three different dyes, and optimal interval time. The detected sites were excised and pathologically evaluated on its morphology. Next, the feasibility and safety were validated in porcine model for clinical usage. After injection of fluorescein, pCLE was applied for the observation of intra-abdominal organs. RESULT: A miniature probe-type pCLE system with 60 µm focal depth (UltraMini O) and 1 % fluorescein dye was chosen for good visualization in mice model. The irregular microarchitecture images suspected to malignancy were obtained from the metastases. In the porcine model, observation of abdominal organs was feasible without any organ injury in the laparoscopic procedures. The dosage of 1 % fluorescein (3 ml/body) was appropriate in observing intra-abdominal organs, and each intra-abdominal organ was clearly observed with the same imaging quality we obtained in mice model. CONCLUSION: The pCLE was feasible and safe and potentially useful for the diagnosis of the peritoneal metastasis in in vivo animal models.

The latest technique of transvaginal NOTES partial gastrectomy is described in detail. The procedure involves new "over-tube steering" technique and usage of two newly developed endoscopic accessories. The technique is feasible, safe, and practical, since all devices used in the case are off-the-shelf products.
RESUMEN
There is no standard therapy for advanced gastric cancer patients who had already failed treatment with major anti-cancer drugs including fluoropyrimidine, cisplatin, taxans, and irinotecan. We report the results of treatment with capecitabine and cisplatin(XP)after the failure of all other conventional therapies. A total of five advanced gastric cancer patients were treated. The median age was 59 years(range, 46-76); there were 3male and 2 female patients; performance status was 0/1/2: 2/2/ 1 patients, respectively. The median duration from start of first-line chemotherapy to XP was 653 days(range, 372-1,107). Three patients were treated after fourth-line therapy and two patients after fifth-line therapy. All of the patients had received S-1, cisplatin, irinotecan, paclitaxel, and docetaxel previously. Patients received 80mg/m2 of cisplatin intravenously on day 1, and 1,000mg/m2 of capecitabine orally twice a day from day 1 to day 14 followed by a 7-day rest period. Treatment courses were between 2 to 5. Median time to progression was 107 days. Median overall survival was 245 days. One PR and one SD were reported. All reported adverse events were manageable. XP is considered one of the effective regimens for advanced gastric cancer after all conventional therapies have failed.

We report a case of advanced gastric cancer successfully treated with preoperative S-1/Lentinan (LTN)chemotherapy followed by curative gastrectomy. The patient was a 75-year-old man with right hypochondralgia. Endoscopic examination revealed a huge type 2 gastric cancer in the middle body of the stomach. Abdominal computed tomography (CT) revealed multiple perigastric lymph node metastases and bulky para-aortic lymph node metastases. The clinical diagnosis was cT 4N3M1( LYM) with cStage IV. We thought a complete resection would be difficult, so he was treated with S-1( 80 mg/m2 day 1-28/q6w) and LTN (2 mg weekly) in May 2010. After 3 courses, the primary lesion was markedly reduced, and gastric endoscopic biopsy showed no malignant lesion. After 4 courses, abdominal CT showed no lymph node swelling at the perigastric and para-aortic areas. After 5 courses, distal gastrectomy with D2 lymphadenectomy was performed. The histological diagnosis was ypT2( MP) N0M0, Stage IB. Histological features of the primary tumor and lymph nodes were judged to be Grade 2 and Grade 3, respectively. After surgery, S-1/LTN treatment was continued for 1 year. During this period, there were no serious adverse events. The patient has been in good health without recurrence for 28 months after surgery.

We report a case of human epidermal growth factor receptor(HER)2-positive advanced gastric cancer successfully treated with a combination of capecitabine, cisplatin(CDDP), and trastuzumab as first-line chemotherapy. A 66-year-old woman diagnosed as having advanced gastric cancer underwent chemotherapy after abdominal computed tomography (CT)revealed multiple metastases to the liver, lung, lymph nodes, and peritoneum. Histopathological examination indicated a type 3, tub1, cT3(SS), N3, H1, P1, M1(LYM, PUL), cStage IV gastric tumor. Because overexpression of HER2 protein was observed in primary tumor immunostaining, combination therapy of capecitabine+CDDP+trastuzumab was administered as first-line chemotherapy. After 4 courses, CT scans revealed decreased primary tumor size, liver lesion, lymph nodes, and elimination of the lung lesion, thereby suggesting a partial response(PR). The grade 3 adverse events were neutropenia, anemia, and anorexia. After discontinuation of CDDP because of elevation of serum creatinine levels, combination therapy with capecitabine and trastuzumab was continued.
