RESUMO

BACKGROUNDS: Intestinal ischemia of strangulated small bowel obstruction (SSBO) requires prompt identification and early intervention. This study aimed to evaluate the risk factors and develop a prediction model of intestinal ischemia requiring bowel resection in SSBO. METHODS: This was a single-center, retrospective cohort study of consecutive patients underwent emergency surgery for SSBO from April 2007 to December 2021. Univariate analysis was performed to identify the risk factors for bowel resection in these patients. Two clinical scores (with contrasted computed tomography [CT] and without contrasted CT) were developed to predict intestinal ischemia. The scores were validated in an independent cohort. RESULTS: A total of 127 patients were included, 100 in the development cohort (DC) and 27 in the validation cohort (VC). Univariate analysis showed that high white blood cell count (WBC), low base excess (BE), ascites and reduced bowel enhancement were significantly associated with bowel resection. The ischemia prediction score (IsPS) comprised 1 point each for WBC ≥ 10,000/L, BE ≤ -1.0 mmol/L, ascites, and 2 points for reduced bowel enhancement. The simple IsPS (s-IsPS, without contrasted CT) of 2 or more had a sensitivity of 69.4%, specificity of 65.4%. The modified IsPS (m-IsPS, with contrasted CT) of 3 or more had a sensitivity of 86.7%, specificity of 76.0%. AUC of s-IsPS was 0.716 in DC and 0.812 in VC, and AUC of m-IsPS was 0.838 and 0.814. CONCLUSION: IsPS predicted possibility of ischemic intestinal resection with high accuracy and can help in the early identification of intestinal ischemia in SSBO.

RESUMO

We report the case of long-term survival of a patient with advanced antral gastric cancer with multiple paraaortic lymph nodes metastasis who was successfully treated with multidisciplinary therapy. A 70-year-old female was admitted to our hospital complaining of vomiting. Upper gastrointestinal endoscopy revealed a Type 3 tumor in the gastric antrum. Computed tomography(CT)showed a marked decrease in the size of the primary gastric tumor and lymph nodes after 9 courses of mFOLFOX6 therapy. Subsequently, 7 courses of paclitaxel plus ramucirumab(PTX plus Rmab)therapy and 10 courses of nivolumab therapy were administered. After nivolumab therapy, marked shrinkage of the lymph nodes was observed on CT. Distal gastrectomy with D2(+ #16a2+b1)lymph node dissection was performed. The pathological finding was ypT0N1M0 with a Grade 3 effect of the chemotherapy. After 6 months of adjuvant chemotherapy with S-1, CT revealed supraclavicular lymph node metastases. After 4 courses of nivolumab therapy, CT showed a marked increase in the size of the lymph node. Consequently, the regimen was changed to irinotecan. After 16 courses of irinotecan therapy, CT showed a marked shrinkage in the size of the lymph node. The patient is currently alive with no signs of recurrence for 5 years, ie, since the initiation of the multidisciplinary therapy.

RESUMO

The patient is a 22-year-old, female. She had a family history of familial adenomatous polyposis(FAP)and a prophylactic total colorectal resection was performed for FAP at age of 18. She presented with fever and abdominal distention and palpated a mass with tenderness in the right lower abdomen. Contrast-enhanced CT scan of the abdomen showed a heterogeneous contrast effect around the tumor margins. With the diagnosis of intra-abdominal desmoid tumor, a partial duodenal resection, small bowel mass resection, and right fallopian tube resection were performed along with the tumor, and an artificial anus was created with the jejunum. Contrast-enhanced CT scan of the abdomen 16 months after resection of desmoid tumor showed a 6.5 cm long desmoid tumor recurrence in the mesentery. She received 5 courses of doxorubicin (DOX)plus dacarbazine(DTIC)therapy followed by continued NSAIDs. Seven years after the operation, she has been able to maintain the shrinkage of the recurrent tumor and is still on medication. Long-term surveillance is necessary because of the possibility of the appearance of other associated lesions in the future.

RESUMO

The patient was a 21-year-old male. He presented with right lower abdominal pain and showed tenderness in the same area. An abdominal contrast-enhanced CT examination revealed a 45 mm tumor that continuously stained in the right transverse colon. The patient presented with tenderness and rebound tenderness. Due to a suspected submucosal tumor, laparotomy was performed and an elastic hard tumor of 5 cm in size was found on the serous membrane side of the right transverse colon. As malignancy could not be ruled out, a right hemicolectomy with lymph node dissection was performed. The pathological diagnosis was an inflammatory myofibroblastic tumor(IMT), characterized by the proliferation of spindle- shaped spindle-shaped fibroblast-like cells with inflammatory cell infiltration. As of 9 years post-surgery, there has been no recurrence. However, long-term surveillance is necessary.

RESUMO

The patient was a 100-year-old woman who underwent right lobe thyroidectomy for papillary thyroid cancer in another hospital around 1990. She developed local recurrence in 2010 and underwent anterior tracheal local recurrence resection in May 2017. Subsequently, metastases were confirmed in the lateral cervical lymph nodes, but the patient only received TSH suppression because of her advanced age. Multiple pulmonary metastases developed in November 2020 and supraclavicular lymph node metastases in July 2021, but the patient was under the care of a visiting physician on best supportive care. The patient was referred to our hospital in January 2022 due to the appearance of a cutaneous mass in the sternal incision area, which gradually increased in size. A well-mobile, well-defined, spherical mass was found in the sternotomy area. The maximum diameter was 19 mm. The cytological findings were consistent with cutaneous metastasis of papillary thyroid carcinoma. As the patient was elderly and had multiple pulmonary metastases, she was temporarily observed. However, by June 2022, the mass had increased from 19 mm to 33 mm with cutaneous discoloration. There was no tendency for multiple pulmonary metastases to grow during this period. The decision was made to operate in order to prevent a decline in quality of life due to self-destruction of the cutaneous metastasis. The tumor was removed under general anesthesia, including the cutaneous discoloration, and reconstructed with a rhomboid skin flap. Post-operatively, there was no local recurrence or significant increase in pulmonary metastases. It is suggested that resection of cutaneous metastasis of malignant tumors may be effective in preserving quality of life even in a 100-year-old elderly patient like the present case and should be considered as an indication.

RESUMO

Perforation of esophageal cancer is one of the fatal oncologic emergencies, and a prompt and accurate treatment strategy is required. Here, we report a case of advanced esophageal cancer that had perforated during preoperative chemotherapy and was successfully resected with multidisciplinary treatment. The prognosis of perforated esophageal cancer can be expected to improve by multidisciplinary treatment appropriately combining initial treatment for infection control and subsequent cancer treatment.

RESUMO

A 74-year-old woman with a chief complaint of hematochezia was admitted to our hospital. Colonoscopy revealed a 2 cm submucosal tumor with an erosion in the Rb of the rectum. Biopsy showed various inflammatory cell clusters, but no malignant findings. Thoracoabdominal CT and abdominal MRI showed no abnormal findings other than that of rectal wall thickening. Somatostatin receptor scintigraphy performed on suspected rectal NET showed no abnormal accumulation. A total of 3 biopsies were performed, but a definitive diagnosis was not confirmed, and transanal rectal mucosal resection was performed for diagnostic purposes. Immunohistochemistry showed CD20(+)and bcl-2(+), and the lesion was diagnosed as malignant rectal B cell lymphoma. For 1 year postoperatively, the patient showed no recurrence. For this case, biopsy often failed to confirm a definitive diagnosis on rectal submucosal tumors. If the tumor is >1 cm in diameter in a rectal NET, a rectal resection with lymph node dissection is required, and anal function may be impaired. Local tumor excision for diagnosis and treatment may be worthwhile in rectal submucosal tumors if pre-resection diagnosis with biopsy is difficult.

RESUMO

In nivolumab therapy for unresectable advanced esophageal cancer, there are a few cases that show a complete response, and long-term survival can be expected in such cases. Here, we report a case in which nivolumab had a complete response to multiple lymph node metastases during multidisciplinary treatment for esophageal cancer and survived for a relatively long period despite being elderly. Examination of complete response cases provides us with significant insights in considering the unexplained biomarkers of immune checkpoint inhibitors and treatment discontinuation during complete response.

RESUMO

Disseminated intravascular coagulation(DIC)has a poor prognosis in gastric cancer. The patient was a 78-year-old man. He had been diagnosed with Stage Ⅳ gastric cancer. Before chemotherapy, thrombocytopenia and elevated D-dimer occurred, and we diagnosed DIC. We started SOX therapy to treat gastric cancer with DIC. DIC improved on the 10th day after the onset of DIC. But developed DIC again on the 21st day. We started SOX therapy again. However, the DIC did not improve. The patient died 32 days after the initial DIC. Oxaliplatin regimen may be a potential treatment for DIC.

RESUMO

The patient was a 60's man, whose chief complaints were melena and weight loss. He visited our hospital, and further evaluation revealed rectal cancer(Ra)invading the abdominal wall with multiple liver metastases. The clinical diagnosis was cT4b(abdominal wall)N2bM1a(H1), cStage Ⅳ. We performed a transverse colostomy on the day prior to chemotherapy administration. He was administered 8 courses of FOLFOXIRI plus bevacizumab. After the chemotherapy, the primary tumor and liver metastases showed PR, with a diagnosis of ycT3N1bM1a(H1), Stage Ⅳ. We performed a robot-assisted laparoscopic low anterior resection for the primary tumor. Two months later, the partial resection of liver S6 and S8 was performed. The patient has been cancer-free for 6 months now.

RESUMO

A 60s-year-old male, who had laparoscopic partial colectomy with resection of left colic artery for descending colon cancer 8 years ago and completed 5-year-follow-up without the evidence of recurrence, was diagnosed as anastomotic recurrence of descending colon cancer, and referred to our hospital. We planned and safely performed single-incision laparoscopic colectomy(SILC)with intracorporeal anastomosis(ICA)(operation time of 390 min and estimated blood loss of 60 g). Following the adhesiolysis, the intracorporeal resection of the lesion was performed with automatic stapling device preserving middle colic and inferior mesenteric arteries and veins. Then, after the recovery of the specimen, ICA was performed as follows; after making a small hole just below the staple line at the opposite side of mesenteric attachment, the oral and the anal stump of colon was pulled-up and placed side-by-side with temporary strings and automatic suturing device was inserted into the holes and fired to form a side-to-side anastomosis, then the common stab incision was pulled- up with 3 temporary strings and closed with a stapler. The postoperative course was smooth and discharged on postoperative day 8. The ICA can be a good option for SILC when colonic and vascular tension would be the limiting factor of anastomosis.

RESUMO

PURPOSE: Pancreatic fistula (PF) is a common and serious complications after pancreaticoduodenectomy (PD). However, few studies have discussed the time required for PF healing in patients with this complication. This study investigates the PF healing time (PF-HT) and its association with findings of postoperative fistulography performed via the drainage tubes. METHODS: The subjects of this study were 35 patients with PF among a total of 144 patients who underwent PD for periampullary diseases in our hospital. PF-HT, which was defined as the duration from the first postoperative fistulography to removal of the drainage tubes, was assessed in the enrolled patients. Fistulography findings were classified into four types based on fluid collection and communication with the jejunal loop. We investigated the factors affecting the PF-HT, including the fistulography findings. RESULTS: The average PF-HT was 22 ± 20 days. Multivariate analysis revealed that the fistulography type was the only independent factor that affected PF-HT significantly. The PF-HT was significantly shorter in patients without fluid collection than in those with fluid collection. Moreover, those patients with fluid collection and a communication had a significantly shorter PF-HT than those without a communication. CONCLUSIONS: We found that fistulography findings were significantly associated with the PF-HT. This suggests that fistulography findings could help to predict the time needed for PF healing.

RESUMO

PURPOSE: Anatomical variation of the cystic duct (CD) is rare but can result in misunderstanding of the CD anatomy during laparoscopic cholecystectomy, potentially leading to bile duct injury. Therefore, the precise preoperative identification of CD variation is important. However, preoperative imaging analyses of the biliary system are not always possible or sufficient. We therefore investigated CD variations based on the anatomy of the hepatic vasculature. METHODS: This study enrolled 480 patients who underwent imaging before hepatobiliary pancreatic surgery. We assessed the variation of the CD and hepatic vasculature and evaluated the correlations among these variations. RESULTS: A variant CD anatomy was identified in 12 cases (2.5%) as CD draining into the right hepatic bile duct (BD) in 4 cases and into the right posterior BD in 8 cases. CD variation was significantly more common in cases with portal vein (PV) and BD variation than in those without the variation. We developed a scoring system based on the presence of PV and BD variations that showed good discriminatory power for identification of CD variants. CONCLUSION: Cases with a variant CD anatomy were more likely to exhibit variant PV and BD anatomies than cases with a normal CD anatomy. These findings will be useful for the preoperative identification of CD variants.

RESUMO

CASE: A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver. CONCLUSION: Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.

RESUMO

A 70-year-old woman underwent treatment for cecal cancer(pT4bN1M0, Stage Ⅲb)in 2010. Four years and 2 months after the first surgery, she underwent ileum resection for stenosis due to perineal dissemination(P3). Two years after this recurrence, during which time she had completed 26 courses of FOLFIRI plus bevacizumab(Bmab), 9 courses of capecitabine plus oxaliplatin(CapeOX)plus Bmab, and 3 courses of Cape, no peritoneal dissemination was detected by computed tomography( CT). Thereafter, an additional 19 courses of Cape plus Bmab were introduced, but CEA continued to increase. Right ovarian metastasis was suspected based on CT and FDG-PET/CT examination. Four years and 1 month after the initial recurrence of perineal dissemination, the patient underwent bilateral ovarian resection, during which the lack of peritoneal dissemination was confirmed. Pathologically, right ovarian metastasis was diagnosed. The patient is still alive 4 years and 6 months after the first operation.

RESUMO

We describe a case of residual stomach preserving surgery performed under evaluation of residual gastric blood flow with indocyanine green(ICG)fluorography, for gastric cancer with recurrence of splenic lymph node metastasis after distal gastrectomy( DG)in a 65-year-old man. After 4 courses of S-1 plus CDDP(SP)therapy for advanced gastric cancer with ascites, DG, D2 dissection, and Billroth Ⅰ reconstruction were performed and radical resection was obtained(L, Type 3, pap/tub, ypT3N1H0P0CY0M0, ypStage ⅡB). Three years and 6 months after the surgery, a mass 4 cm in diameter was found in the splenic hilum, and a pancreatosplenial resection was performed to remove the tumor for diagnosis and treatment purposes. We confirmed that there was no problem with blood flow, and we were able to preserve the stomach. Intraoperative ICG fluorescence imaging was considered a promising method for evaluating residual gastric blood flow.

RESUMO

Follicular cholangitis is a new, rare disease that causes severe biliary stricture. We herein describe the findings from a resected case of follicular cholangitis, suggesting a distinct disease entity that causes benign biliary stricture. A 60-year-old man who was referred to our hospital due to elevated γ-glutamyl transpeptidase levels and dilatation of the B8 bile duct. Although bile juice cytology and bile duct brushing cytology showed no malignancy, the dilatation was progressive. Therefore, right hepatectomy combined with caudate lobectomy was carried out on suspicion of intrahepatic cholangiocarcinoma. The wall of the resected bile duct was markedly thickened due to severe fibrosis under the mucosal layer. Histology of the mucosal epithelium indicated no malignancy. Infiltration of plasma cells characterized by remarkable formation of lymphoid follicles with germinal centers was observed around the bile ducts. The patient was diagnosed with follicular cholangitis based on histological findings. We thus observed a rare case of follicular cholangitis. This case and review of published reports suggest that, despite its rarity, follicular cholangitis should be considered at the differential diagnosis of biliary stricture. This case report could contribute to a better understanding of how to address this disease.

RESUMO

There have been few reports discussing treatments for primary duodenal cancer. In this study, 15 cases of primary duodenal cancer that were treated by curative resection in our hospital between April 2005 and December 2017 were analyzed to study appropriate operative procedures. Prognostic analysis revealed that the median of relapse-free survival and overall survival were 49 months and 74 months, respectively. The 5-year survival rate was 47%. On univariate analysis of relapse-free survival, lymph node metastasis(p<0.01)and post-operative adjuvant therapy(p=0.02)were significant independent prognostic factors. Analysis of the relationship between lymph node metastasis and the depth or location of tumors suggested that pancreaticoduodenectomy with lymph node dissection should be performed to achieve radical resection, since there were some cases that involved lymph node metastasis around the pancreatic head or hepatoduodenal ligament.

RESUMO

A60s woman was followed-up regularly for primary biliary cholangitis and a solitary enlarging hepatic mass in the S6 segment of her liver was discovered by ultrasonography. We diagnosed the mass as hepatocellular carcinoma by contrast ultrasonography, contrast computed tomography, and ethoxbenzyl magnetic resonance imaging and laparoscopic partial hepatectomy of S6 segment was performed. The resected specimen was histopathologicaly diagnosed as liver-reactive lymphoid hyperplasia(RLH). The patient is alive without recurrence 17 months after the surgery. Although liver RLH is a rare disease, it should be considered in the differential diagnosis of small liver tumors.

RESUMO

A 68-year-old man underwent a subtotal stomach-preserving pancreatoduodenectomy(SSPPD)for a distal bile duct carcinoma(BDC)pT3aN1M0, pStage ⅡB and adjuvant chemotherapy with gemcitabine. One year 7 months after the initial surgery, CT revealed a nodule with an increasing tendency in the left lung. As it was difficult to distinguish primary lung cancer from BDC lung metastasis, we performed a thoracoscopic left wedge resection. The histopathology of the resected specimen was BDC lung metastasis. In the follow-up with adjuvant chemotherapy with S-1 for 10 months, 2 nodules were found in the right lung, and we performed thoracoscopic right S6 segmentectomy. Eight months later, another nodule was found in the left lung, and we performed thoracoscopic left wedge resection. The histopathology was BDC lung metastasis for all the resected specimens. The patient is alive with no evidence of recurrence after 9 months of the latest surgery(4 years 11 months after the initial surgery). Although the standard treatment for metastatic recurrence of BDC is systemic chemotherapy, some cases treated with surgical resection had relatively good prognosis, such as the present case. Surgical resection might be feasible as a treatment option for metastatic recurrence of BDC.
