Laparoscopic Removal of an Infected Mesh Following TEP Procedure for Femoral Hernia with Omental Patch Closure of a Peritoneal Defect.

BACKGROUND Mesh infection following inguinal hernia repair is rare, and mesh removal is mandatory. However, the laparoscopic approach is challenging to perform. Here, we present a case of laparoscopic repair of a mesh infection using a totally extraperitoneal approach (TEP). CASE REPORT A 76-year-old woman underwent repair of a right femoral hernia via TEP approach using a prosthetic mesh with unabsorbable tacks. A month and a half after the surgery, she reported pain in the right groin. Computed tomography revealed a subcutaneous abscess in the right groin. We suspected mesh infection and initially chose conservative management, which included percutaneous drainage and systemic antibiotic administration. Her symptoms temporarily resolved; however, symptom relapse and purulent discharge from the right groin were observed. We performed laparoscopic removal of the infected mesh and all tacks via the transabdominal preperitoneal approach. A drain was placed in the infected preperitoneal space, and the peritoneal defect was covered using the greater omentum. The patient's postoperative course was uneventful, and she was discharged on postoperative day 20. Infection relapse, symptoms of femoral hernia, and adhesive intestinal obstruction have not been observed. CONCLUSIONS A laparoscopic approach for mesh infection after TEP hernia repair is feasible, even if the mesh is fixed using a tack. Greater omental use for peritoneal defects is useful in clinical situations associated with a contaminated surgical field.

Urgent versus elective laparoscopic cholecystectomy following percutaneous transhepatic gallbladder drainage for high-risk grade II acute cholecystitis.

BACKGROUND: The aim of this study was to evaluate the safety of urgent laparoscopic cholecystectomy (Lap-C) for grade II acute cholecystitis (AC) in high-risk patients who were defined by Tokyo Guideline 18 as having age-adjusted Charlson comorbidity index ≥6 or American Society of Anesthesiologists physical status classification (ASA-PS) ≥ 3, compared with elective Lap-C following percutaneous transhepatic gallbladder drainage (PTGBD). METHODS: In 73 grade II AC patients who underwent Lap-C from January 2012 to March 2021, 35 were identified as high-risk; 22 underwent urgent Lap-C (urgent group) and 13 PTGBD followed by elective Lap-C (elective group). Surgical and perioperative outcomes were analyzed. RESULTS: There was no significant difference in operation time (median: 101 min vs 125 min; P = 0.371), blood loss (25 ml vs 7 ml; P = 0.853), morbidity rate (31.8% vs 38.5%; P = 0.726), or the incidence of total perioperative major complications (13.6% vs 15.4%; P = 1.000) between the two groups. The total duration of treatment was significantly shorter in the urgent group than the elective group (11 days vs 71 days; P < 0.001). Multivariate analysis revealed that blood loss ≥45 ml [odds ratio (OS): 12.14, 95% confidence interval (CI): 2.03-72.42, P = 0.006], and age ≥75 years with ASA-PS ≥ 3 (OS: 9.85, 95%CI: 1.26-77.26, P = 0.03) were the independent risk factors for total perioperative major complications. CONCLUSION: In well-selected high-risk patients with grade II AC, urgent Lap-C can be performed with comparable safety to elective Lap-C following PTGBD.

Case Report of a 58-Year-Old Woman with Anatomic Segment IV and VII Liver Metastases from a Primary Colonic Adenocarcinoma Who Underwent Laparoscopic Cone Segmental Partial Hepatectomy.

BACKGROUND Compared with wedge resection, anatomic segmental resection of liver metastases from primary colon cancer can improve tumor clearance and patient survival. We present the case of a 58-year-old woman with liver metastases from primary colon cancer who underwent laparoscopic cone unit resection for undetectable liver metastasis of segment VII. CASE REPORT The patient was a 58-year-old woman. Giant uterine myoma and advanced sigmoid colon cancer were detected on computed tomography. Two liver metastases (segments IV and VII) were simultaneously detected. The lesion of segment VII (5.0 mm in size) was not detected by echography and was located in the root of the hepatic vein, which connects to the right hepatic vein. However, the echography detected the hepatic vein. Therefore, we set the vein as the landmark of the undetectable liver tumor and planned to perform cone unit resection of segment VII with resection of the hepatic vein laparoscopically. We detected the landmark-set hepatic vein on intraoperative echography and transected the peripheral Glisson VII. Subsequently, the right hepatic vein was exposed from the root to the peripheral side and transected in its root. Cone unit resection was performed without tumor exposure. Operation time and blood loss were 582 min and 200 g, respectively. Pringle maneuver time, including hepatectomy of segments IV and VII, was 146 min. She was discharged on postoperative day 5 with no postoperative complications. CONCLUSIONS This case demonstrated the use of laparoscopic cone unit hepatectomy using an anatomical landmark in a patient with undetectable liver metastasis.

Limitations of the L3 skeletal muscle index and the Asian Working Group for Sarcopenia 2019 consensus diagnostic criteria for sarcopenia evaluation in a case of diffuse large B-cell lymphoma.

Sarcopenia is an adverse prognostic factor for diffuse large B-cell lymphoma. A case of diffuse large B-cell lymphoma whose diagnosis, severity, and therapeutic effect of sarcopenia were difficult to determine owing to lymphoma cell infiltration into the psoas major and femoral bone marrow is reported. At presentation, the cross-sectional area of left psoas major at L3 was enlarged owing to lymphoma cell infiltration; thus, sarcopenia evaluation was impossible by L3 skeletal muscle index. The patient was bedridden; thus, sarcopenia evaluation was impossible by the Asian Working Group for Sarcopenia 2019 consensus diagnostic criteria at presentation. At the terminal stage, she could not walk due to bilateral anterior thigh pain caused by lymphoma infiltration into femoral marrow; thus, sarcopenia evaluation was impossible by the Asian Working Group for Sarcopenia 2019 consensus diagnostic criteria. Although the L3 skeletal muscle index and the Asian Working Group for Sarcopenia 2019 consensus diagnostic criteria are representative sarcopenia evaluation systems, they cannot be used to evaluate sarcopenia in some diffuse large B-cell lymphoma patients.

Predictive factors of perforated appendicitis: Impact of the C-reactive protein level.

BACKGROUND: Perforated appendicitis without an associated abscess necessitates emergency surgery. However, it is difficult to predict the presence of perforation before surgery, and the predictive factors are still unclarified. Our purposes were to characterize a patient population with perforated appendicitis without an associated abscess to identify the preoperative predictive factors of appendiceal perforation. METHODS: We retrospectively identified 150 patients who underwent appendectomy for acute appendicitis at our institution from June 2018 to November 2020. Logistic regression analysis was performed to analyze the concurrent effects of various factors on the prevalence of perforated appendicitis. RESULTS: Forty (29%) of 150 patients had appendiceal perforation detected intraoperatively. Of these 40 patients, only 19 had appendiceal perforation detected on preoperative computed tomography. Multivariable analysis found that a higher C-reactive protein level, higher total bilirubin level, and the presence of an appendiceal fecalith were independent predictive factors for appendicitis with perforation. CONCLUSION: Our analysis suggests that the presence of an appendiceal fecalith, a total bilirubin level of more than 21.38 µmol/L, and a C-reactive protein level of more than 3.0 × 104 µg/L are predictive factors of perforated appendicitis.

Chronic expanding hematoma mimicking seroma, following a totally extraperitoneal approach for inguinal hernia: a case report.

Chronic expanding hematoma (CEH) mimicking seroma following inguinal hernia surgery has not been reported previously. A 78-year-old man underwent laparoscopic repair of a left direct hernia via a totally extraperitoneal approach. He was discharged 2 days after surgery without any complications. Two weeks later, he complained of left inguinal bulging without pain. We considered seroma and decided to observe the patient for 1 month. However, the cyst did not change in size. Additional cyst aspiration and drainage attempts were unsuccessful. Three months after the initial surgery, we performed a second surgery (resection of the cyst) because conservative therapies were ineffective. The resected cyst was pathologically diagnosed as a CEH. The postoperative course was uneventful, and no recurrence was observed. Complete excision of a CEH is mandatory because aspiration and drainage cannot prevent recurrence.

Successful Treatment of Protein-Losing Enteropathy After Superior Mesenteric Artery Occlusion without Surgery.

BACKGROUND Protein-losing enteropathy as a complication of superior mesenteric artery occlusion is extremely rare and severe, and sometimes requires intestinal resection. However, the ideal treatment strategy has not yet been determined. CASE REPORT A 77-year-old man with underlying hypertension and diabetes was admitted to the Emergency Department with acute abdominal pain after eating. Contrast-enhanced computed tomography revealed complete occlusion of the superior mesenteric artery with thrombosis, and superior mesenteric artery occlusion was diagnosed. It was successfully treated with interventional therapy, followed by continuous intra-arterial prostaglandin E1 infusion and continuous intravenous heparin infusion. However, the patient developed hypoproteinemia and diarrhea about 10 days after the interventional therapy. Colonoscopy and X-ray studies did not reveal any abnormal findings; however, technetium-99m-labeled human serum albumin scintigraphy indicated protein-losing enteropathy. With total parenteral nutrition and protein-rich oral nutrition, with protein intake at twice the amount in a standard diet, serum albumin improved from 15 g/L to 32 g/L after treatment. Additionally, we administered diuretics to avoiding edema related to the hypoproteinemia. The patient recovered from the hypoproteinemia and diarrhea without complications. CONCLUSIONS Protein-losing enteropathy is an extremely rare but critical complication of superior mesenteric artery occlusion. Treating the underlying pathology is the mainstay of protein-losing enteropathy and dietary modifications also play a critical role. Our patient was successfully treated with strict nutritional therapy, combined oral protein-rich nutrition and total parenteral nutrition, which avoided surgery.

Preventive Effect of High-Dose Digestive Enzyme Management on Development of Nonalcoholic Fatty Liver Disease after Pancreaticoduodenectomy: A Randomized Controlled Clinical Trial.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a complication of pancreaticoduodenectomy (PD). We conducted a randomized clinical trial to determine if high-dose digestive enzymes prevented the development of NAFLD after PD. STUDY DESIGN: This parallel-group, nonblinded, multicenter study enrolled patients undergoing elective PD at Shinshu University School of Medicine, from June 2011 to April 2017. Patients were randomly assigned to receive normal-dose (Excelase: 3.0 g/day [Meiji Seika Pharma Holdings Co, Ltd]) or high-dose digestive enzyme treatment (Excelase: 3.0 g/day; Pancreatin [Tokyo Chemical Industry Co Ltd]: 3.0 g/day; Berizym [Kyowa Pharmaceutical Industry Co Ltd]: 3.0 g/day; and Toughmac-E [Ono Pharmaceutical Co, Ltd]: 3.0 g/day) within 1 week after surgery. Because patients in the control group switched interventions upon receiving a diagnosis of NAFLD, intention-to-treat analysis was used. The primary endpoint was incidence of NAFLD within 1 year, and the secondary endpoints were the incidences of NAFLD at 1, 3, 6, and 12 months and the rate of improvement in NAFLD with high-dose transfer in the control group. The secondary analysis comprised assessment of risk factors for the development of NAFLD. RESULTS: Eighty-four patients were randomly assigned (42 per group), 80 of whom were finally analyzed (39 normal-dose, 41 high-dose). The incidence of NAFLD was significantly lower in the high-dose (8 of 41) compared with the normal-dose (25 of 39) patients (p < 0.001). Multivariate analysis identified normal-dose (odds ratio [OR] 14.65, p < 0.001), total protein ≤ 6.5g/dL (OR 9.01, p = 0.018), pre-albumin ≤ 22.0 mg/dL (OR 7.71, p = 0.018), and pancreatic function diagnostic test ≤ 70% (OR 6.66, p = 0.009) as independent risk factors. There were no adverse effects. The model was accurate (c-index = 0.92) and reliable (Hosmer-Lemeshow test p = 0.32). CONCLUSIONS: High-dose administration of digestive enzymes significantly reduced the onset of NAFLD after PD compared with normal-dose administration.

Successful use of ligamentum teres hepatis for perforated duodenal ulcer following omentectomy: a case report.

Our patient was a 59-year-old woman with past history of hysterectomy, bilateral salpingo-oophorectomy, regional lymphadenectomy and omentectomy performed for advanced ovarian cancer. She was experiencing abdominal pain over the past 2 days and visited our hospital owing to pain exacerbation. Contrast-enhanced computed tomography revealed free air around the liver, ascites and duodenal perforation; thus, emergent abdominal surgery was performed. The 5-mm duodenal perforation at the anterior wall of the duodenal bulb was sutured with absorbable thread. We used ligamentum teres hepatis (LTH) as a patch for the sutured site as the greater omentum could not be used. The postoperative course was uneventful, and she was discharged on postoperative Day 8. There were no complications 1 month after surgery. Although the greater omentum is conventionally used for upper gastrointestinal perforation, the LTH was a plausible alternative with good indication in our case.

Gastric volvulus with perforation 1 year after total pancreatectomy: a case report.

BACKGROUND: Because of its rare indication and relatively simple reconstruction procedure (only choledochojejunostomy and gastrojejunostomy) compared to those for pancreatoduodenectomy, the technical tips and pitfalls of total pancreatectomy are rarely discussed. Herein, we discuss a rare case of gastric volvulus 1 year after total pancreatectomy and provide advice to prevent such cases. CASE PRESENTATION: A 66-year-old woman underwent total pancreatectomy with splenectomy for mixed-type intraductal papillary mucinous neoplasm of the pancreas. Choledochojejunostomy (retro-colic route) and gastrojejunostomy (ante-colic route, Billroth II method) were performed for reconstruction. The final diagnosis was mixed-type intraductal papillary mucinous adenoma of the pancreas without malignant neoplasm. She had no clinical symptoms, such as abdominal pain and fever, during postoperative follow-up. However, at 1 year postoperatively, she complained of abdominal pain. Contrast-enhanced abdominal computed tomography showed volvulus and perforation of the stomach. Emergent surgery was performed. The stomach fornix was located on the right side and was partly perforated. We resected the perforation site with a linear cutter® (New Type Linear Cutter, Ethicon, USA) and released the gastric volvulus. Moreover, we fixed the stomach to the left abdominal wall using non-absorbable thread. The cause of the perforation was clinically and pathologically unclear. Her serum albumin and cholinesterase levels temporarily decreased postoperatively, but gradually increased. A recurrence of volvulus-related symptoms has not been observed. CONCLUSIONS: After total pancreatectomy with splenectomy, although the stomach is connected with the jejunum, it is typically fixed only by the pedicle of the left gastric artery and vein. In the present case, this anatomical change may have been a cause of the gastric volvulus. Thus, it might be better to fix the remnant stomach in total pancreatectomy with splenectomy.

Successful management of chylous ascites after pancreatoduodenectomy using etilefrine: a case report.

An 84-year-old woman underwent subtotal stomach pancreatoduodenectomy (PD) for distal cholangiocarcinoma. Over 1000 ml of serous ascites, which appeared milky after starting a high-protein, low-fat, middle-chain triglyceride diet, was discharged from the inserted drain. On postoperative day (POD) 13, she underwent right hemicolectomy for transverse colonic volvulus, which occurred on POD 9 and was refractory to conservative therapies. Following second surgery, the chylous ascites (CA) amount continued to increase. Octreotide, albumin and diuretics were administered, but the amount of ascites did not decrease. Etilefrine was administered on POD 19; the ascites amount gradually decreased. The drain was removed 3 days after etilefrine administration. She had no symptoms of abdominal distention after drain removal. Etilefrine's effectiveness for chylothorax after esophagectomy and CA after distal pancreatectomy has been reported. We present a case of CA successfully treated by etilefrine following PD. Our case highlights etilefrine's usefulness for CA following PD.

Infected hepatic cyst following pancreatoduodenectomy treated with transhepatic drainage and minocycline hydrochloride injection: A case report.

INTRODUCTION: Asymptomatic hepatic cysts, often observed on computed tomography, have never been reported as a risk factor for infection following pancreatoduodenectomy. Symptomatic liver cysts are treated surgically or non-surgically. We encountered a case of infected hepatic cyst following pancreatoduodenectomy. PRESENTATION OF CASE: An 88-year-old woman underwent pancreatoduodenectomy for adenocarcinoma in the duodenum papilla of Vater. She was discharged (postoperative day 23), following an uneventful course. However, 7 days later, she was re-admitted because of a high fever; postoperative cholangitis was suspected. A peripheral-venous blood bacterial culture was negative. Her C-reactive protein level and white blood cell count were 0.57 mg/dl and 5290/µl, respectively. Antibiotics were administered, but her high fever only temporarily decreased. Contrast-enhanced computed tomography showed ring enhancement surrounding the largest of several hepatic cysts. Percutaneous transhepatic drainage was performed; thereafter, minocycline hydrochloride was repeatedly injected into the infected cyst through the drain to prevent infection recurrence. The drain was removed 49 days after drainage. On contrast-enhanced computed tomography at 6 months postoperatively, the infected hepatic cyst had reduced in size from 6.0 to 1.7 cm and no findings of bile duct stenosis were observed. No further infectious events have been observed. DISCUSSION: Relatively large hepatic cysts may be at risk of infection following pancreatoduodenectomy and, in particular, biliary reconstruction. CONCLUSION: Transhepatic drainage, rather than antibiotic administration, is essential, and minocycline hydrochloride injection into infected cyst that have no evidence of communication with the biliary tree is effective in preventing infection recurrence, without the complication of bile duct stenosis.

Metastatic liver tumor from a primary gastric cancer with infiltration of the Glisson's pedicle: A case report.

INTRODUCTION: Metastatic liver tumors from primary gastric cancer are rarely resected because of the high rate of metastasis and recurrence of gastric cancer, and there is little information regarding the pathological assessment of these tumors. We present a case of a single metastatic liver tumor from gastric cancer with invasion of the interlobular bile duct for which we achieved margin-free resection with good clinical outcomes. PRESENTATION OF CASE: An 80-year-old patient presented with a tumor in segment V of the liver, with invasion of Glisson's pedicle confirmed on preoperative magnetic resonance and positron emission tomography imaging. On the basis of the preoperative assessment, we proceeded with partial hepatectomy, with transection of one of the roots of Glisson's pedicle performed under echography guidance. Pathological examination confirmed gastric cancer as the primary source of the metastatic tumor. R0 resection was achieved, with no evidence of cancer recurrence at one year after surgery. DISCUSSION: Our experience supports partial hepatectomy with R0 margin tumor resection as an oncologically feasible treatment for metastatic liver tumor arising from primary gastric cancer (in the absence of other metastatic lesions) and shows that a good prognosis can be achieved. Of note, intraoperative echography did not detect tumor invasion of Glisson's pedicle, which was evident only on preoperative imaging. CONCLUSION: This case suggests that magnetic resonance and positron emission tomography imaging findings are important for surgical planning of hepatectomy. Further follow-up data and more cases are needed to completely define the clinical significance of tumor invasion of Glisson's pedicle.

Pseudolymphoma with atrophic parenchyma of the liver: Report of a case.

INTRODUCTION: Pseudolymphoma of the liver is a very rare disease. It is usually resected and pathologically diagnosed because of the difficulty of discrimination from the malignant neoplasm. For this reason, few cases which were observed for several years have been reported. We present a case of this disease observed and slightly enlarged for two years. PRESENTATION OF CASES: The patient was a 46-year-old woman who underwent laparoscopic partial nephrectomy for right renal cell carcinoma two years ago. The preoperative computed tomography (CT) showed the mass 7 mm in diameter with localized parenchymal atrophy of the liver (segment Ⅵ). Two years later, CT showed enlarged mass from 7 to 11 mm in diameter. We performed laparoscopic partial hepatectomy because the patient desired definite diagnosis by surgery. The resected specimen showed white and solid mass. The lymphocyte and plasma cells are histologically observed. Immunohistological staining showed CD10 positive, Bcl-2 negative, and cyclin D1 negative. The pathological diagnosis was pseudolymphoma of the liver. DISCUSSION: Pseudolymphoma is rarely observed in the liver. It is reported that chronic hepatitis, collagen diseases, and malignant diseases were often accompanied, but detail pathogenesis has been unknown. She had the history of renal carcinoma, but the lesion was not vanished regardless of clearance of renal neoplasm. Surgical resection is usually performed because discrimination with malignant neoplasm is difficult. The present case is probably the first one, which is followed for long term duration. CONCLUSION: The present case may contribute to clarify the pathophysiology of this entity.

[OPERATIONAL EXPERIENCE OF AUTOMATIC POSTING SYSTEM TO THE NATIONAL CLINICAL DATABASE USING FILEMAKER PRO].

We would like to introduce a semi-automated registration system for the National Clinical Database. Japan Surgery Society runs the National Clinical Database since January 2011. And automated registration system is long-awaited due to the number of cases and diverse items to register. Well-known database management system, FileMakerPro enabled collecting and registering the items to the web-site automatically. Still some items need to copy one by one, but after filling the data, all data would be input to the web page for registration. Merit for this automated system is increasing not only the efficiency of administration work but the quality and the usefulness of this database. This paper is to report the outline of the registration system to the NCD database.

Anatomical Resection of the Bile Duct: A Hidden Door to the Bile Duct.

BACKGROUND/AIMS: Pancreas-preserving resection of the bile duct has been attempted as an organ preserving procedures for the treatment of low-grade malignant neoplasms of the bile duct. The fact that the lower bile duct penetrates pancreas head to join the duodenum, makes those attempts one of the challenging procedures in biliary tract surgery. Here we present a novel and unique surgical technique for anatomically resecting lower bile duct, focusing on the anatomy of the pancreas head. METHODOLOGY: A patient with middle bile duct cancer underwent this procedure. Subsequent to Kocher's maneuver, pancreas head was dissected from the posterior side of the duodenum that was a key step to recognize the embryological fusion plane between the anterior and the posterior pancreatic segments. Along this fusion plane pancreas head was able to be divided and the covering pancreatic parenchyma was split open to expose the whole intrapancreatic bile duct. RESULTS: The patient had no signs of pancreatic fistula and post-operative course was uneventful. Negative surgical margins were obtained thanks to the presented technique. CONCLUSIONS: This procedure might be applicable for the treatment of bile duct neoplasms, in case of lesions spread to the lower bile duct. Otherwise that might require pancreatoduodenectomy.

A novel combined laparoscopic-endoscopic cooperative approach for duodenal lesions.

PURPOSE: A surgical approach with minimal invasion and excellent outcome for removal of duodenal lesions, using laparoscopic-endoscopic cooperative surgery (LECS), was established. PATIENTS AND METHODS: Two patients underwent the resection of duodenal lesions with our novel LECS approach. Case 1 (age: 49 years; male) had a 20-mm 0-IIa-like lesion (group IV tumor on biopsy) in the duodenal bulb. LECS interventions, performed under general anesthesia, employed a total of four trocars. The extent of lesions was determined with the endoscopic submucosal dissection (ESD) technique. The affected duodenal wall was then perforated before a one fifth turn resection was performed to expose lesions of the whole layer. A tumor, confirmed under laparoscopy, was turned over toward the abdominal cavity to facilitate resection. Case 2 (age: 49 years; female) had 20-mm 0-IIc lesions (group III adenoma) located at the second portion of the duodenum. LECS procedures for duodenal resection were performed in a manner similar to case 1 . A total of five trocars were used. RESULTS: Histologic diagnosis of the tumor in case 1 was tubular adenoma with moderate atypia (size: 20 x 12 mm). As for case 2, histopathologic findings confirmed a tubular adenoma with moderate atypia (size: 18 x 18 mm) and an adenoma-negative surgical margin. The postoperative courses, in both cases, were uneventful. CONCLUSIONS: Although only 2 cases were surgically intervened with limited experience, the present novel LECS approach allowed a reliable, adequate resection of tumors located in the duodenum, with abbreviated operation times (156-179 versus 202-229 minutes), minimal bleeding, less postoperative stress imposed on the surgeons, and an uneventful postoperative course, compared to conventional surgical methods.

[A case of complete response (CR) persisting for 3 years and 3 months from combination therapy of S-1 and CDDP in a patient with advanced gastric cancer with multiple liver metastases].

The case was a 70-year-old man with type-2 gastric cancer in the lesser curvature accompanied by multiple liver metastases. He received combination chemotherapy of S-1 and CDDP. S-1 was administered at 100 mg/body/day for 21 days followed by withdrawal for 14 days, and CDDP was prescribed at 80 mg/body/day div on day 8. After 3 courses of treatment, the multiple liver metastases disappeared. The primary gastric lesion had changed to a scar and endoscopic biopsy revealed no cancer cell. After the 4th course, we changed the therapy to S-1 alone and after that to UFT alone. Now, 3 years and 3 months after inducing CR, the patient continues to receive UFT with no regrowth of the tumor.

[A case of advanced gastric cancer responding to paclitaxel/CDDP neoadjuvant chemotherapy leading to pathologically complete response].

A 74-year-old male with advanced gastric cancer(cT3N1M0H0P0CY0, cStage III A)was treated with paclitaxel/ CDDP as neoadjuvant chemotherapy. Paclitaxel (80 mg/m(2)) and CDDP (25 mg/m(2)) were administered on days 1, 8 and 15 as one cycle. After the second course, a significant tumor reduction was obtained. Total gastrectomy, splenectomy, and D2 type nodal dissection were performed. The histological diagnosis revealed complete disappearance of cancer cells in the stomach and all of the lymph nodes, a so-called pathologically complete response. The patient has now been in good health without any recurrence for 9 months after surgery. This case suggests that neoadjuvant chemotherapy with paclitaxel/CDDP is a potential regimen for advanced gastric cancer.
