Robot-assisted low anterior resection for a rectal cancer patient with ileal conduit: A case report.

Surgery for rectal cancer patients with an ileal conduit after total cystectomy is difficult because adhesions in the pelvis and around the ileal conduit are expected. In the present case, we performed robot-assisted low anterior resection of the rectum in a 69-year-old male patient with rectal cancer who underwent ileal conduit diversion after total cystectomy. In this procedure, the port was inserted into the left upper abdomen as a first step, and two additional ports were added on the left side. Low anterior resection was performed using two left hands to create more space in the abdominal cavity for the ileal conduit. We present this minimally invasive robotic procedure that is extremely useful for dissection of adhesions in a narrow pelvic cavity.

Robot-assisted surgery for rectal cancer with solitary sacrococcygeal metastasis after neoadjuvant chemoradiotherapy: A case report.

An 81-year-old man was referred to our hospital for anal bleeding. Colonoscopy revealed a type 3 tumor at the upper rectum and biopsy showed adenocarcinoma. An enhanced circumferential lesion at the upper rectum and a solitary soft-tissue shadow at the fifth sacral vertebra to the coccyx were detected on abdominal magnetic resonance imaging. Fluorodeoxyglucose uptake was observed at the same sites on positron emission tomography. The patient was diagnosed with rectal cancer with isolated sacrococcygeal metastasis and was treated with neoadjuvant chemoradiotherapy followed by robotic surgery. Hartmann's operation was performed in the lithotomy position. The left internal iliac artery and vein were then divided. The internal pudendal artery and vein, the piriformis muscle, and sacrospinous ligament were also divided while preserving the lumbosacral trunk. The scheduled transection line of the sacral surface was fully exposed to prevent massive bleeding during sacrectomy. The dorsal surface of the sacrum was then exposed in the prone position and communicated with the pelvic space. The sacrum was transected at the superior margin of S3 and a specimen was extracted. Pathological findings revealed the infiltration of cancer cells in the sacrococcygeal specimen. The postoperative course was uneventful and the patient was discharged on postoperative day 13.

Robot-assisted anterior resection for rectal cancer with double inferior vena cava: A case report.

Double inferior vena cava (DIVC) is a rare but generally asymptomatic condition that is often detected incidentally by radiological examinations such as computed tomography (CT). Here, we describe the case of a 73-year-old woman with DIVC, who underwent robot-assisted surgery (RS) for rectal cancer. In this case, 3D CT angiography showed DIVC with an interiliac vein from the left common iliac vein and a tortuous aorta. Intraoperatively, we identified the presence of the left IVC in addition to the inferior mesenteric vein, gonadal vein, and ureter, which require meticulous attention during vascular processing. By optimizing the port placement, we were able to ensure mobility of the robotic arm and sufficient field of view to safely perform a robot-assisted anterior resection with lymph node dissection. Careful preoperative assessment and development of a strategy for port placement using CT imaging are essential in avoiding iatrogenic injury and performing safe RS.

Robotic low anterior resection of rectal metastasis from small bowel adenocarcinoma: A case report.

A 69-year-old female underwent laparoscopic ileal partial resection for ileal adenocarcinoma. Pathological diagnosis was moderately differentiated tubular adenocarcinoma (UICC 8th; T4N0M0 StageIIB). The patient received adjuvant chemotherapy with modified 5-fluorouracil/leucovorin/oxaliplatin. Fourteen months after surgery, computed tomography revealed a mass in the upper rectum. Colonoscopy detected a submucosal protruding mass and a biopsy specimen showed moderately differentiated tubular adenocarcinoma. Robotic low anterior resection was performed. The tumor was located in the upper rectum and there was no macroscopic invasion or peritoneal dissemination. Pathologically, the tumor was moderately differentiated tubular adenocarcinoma located within the rectal wall with little evidence of a carcinoma component in the mucosal lining. Immunohistochemistry showed the same pattern as the previous ileal adenocarcinoma: negativity for cytokeratin 7 and positivity for cytokeratin 20 and caudal-type homeobox 2. In combination with the rectum showing no abnormalities in colonoscopy performed 15 mo previously, the mass was considered hematogenous metastasis from small bowel adenocarcinoma.

Laparoscopic resection of a gastrointestinal stromal tumor that recurred more than 15 years after surgery using lighted ureteral catheters: A case report.

A 69-year-old woman underwent abdominoperineal resection for a gastrointestinal stromal tumor (GIST) of the rectum 15 years ago. She received adjuvant chemotherapy for 8 years. Seven years later, abdominal computed tomography revealed a soft-tissue shadow in the left lower abdomen, and fluorodeoxyglucose uptake was observed at the same site on positron emission tomography. The recurrence of GIST was suspected, and laparoscopic resection was performed. Laparoscopy showed that the tumor was located at the retroperitoneum near to the descending colon and invaded the left ovarian vessels. It also made contact with the left ureter; however, lighted ureteral catheters enabled us to identify and preserve the left ureter. An immunohistochemical examination revealed the recurrence of GIST. Recurrence may become apparent 15 years or more after GIST surgery, and, thus, a long-term follow-up is required. Lighted ureteral catheters were useful for identifying the ureter and preventing ureteral injury in a recurrent case suspected of invading the ureter.

Laparoscopic treatment for celiac artery stenosis caused by median arcuate ligament compression with Adachi V type vascular anomaly: a case report.

BACKGROUND: Median arcuate ligament syndrome (MALS), which results from compression of the median arcuate ligament (MAL), is a rare cause of abdominal pain and weight loss. Treatment is dissection of the MAL; however, the laparoscopic procedure is not yet established and it involves the risk of major vascular injury, especially in cases with an anomaly. CASE PRESENTATION: A 47-year-old man was evaluated at the hospital for epigastric pain. Contrast computed tomography scan revealed stenosis of the celiac artery origin due to the MAL. An Adachi V type vascular anomaly was also observed. Laparoscopic treatment was performed to release pressure on the celiac artery. Laparoscopic ultrasonography was used to less invasively confirm the release of the MAL. Despite a concomitant Adachi V type vascular anomaly, surgery was safely performed using the laparoscopic magnification view and intraoperative ultrasonography. Follow-up ultrasonography confirmed the celiac artery stenosis has not recurred. CONCLUSIONS: A rare case of MALS with an Adachi V type vascular anomaly is presented and the laparoscopic treatment is detailed.

Anticipation of umbistoma in laparoscopic anterior rectal resection: Ileostomy and ostomy closure.

OBJECTIVE: The use of laparoscopic surgery for rectal disease is expected to provide good cosmetic benefits for patients postoperatively. However, this expectation is significantly reduced when a diverting ileostomy is created. We present a new technique that reduces the size of the skin wound by constructing a diverting ileostomy in the umbilicus. This procedure, diverting umbilical ileostomy (umbistoma) does not require special tools for its construction and closure. METHODS: Twenty-nine patients underwent treatment with umbilical diverting stoma, including five women and 24 men, with a mean age of 70 years (range: 40-88 years). At the time of ostomy closure, a new umbilicus was formed by subcutaneously suturing the wound to the fascia. In addition, we did not close the new umbilical upper and lower spaces, so as to allow open drainage of the healing wound. RESULTS: All procedures were completed successfully without any perioperative complications. CONCLUSIONS: Our findings suggest that the umbilical diverting stoma could provide improved safety and cosmetic advantages in laparoscopic rectal resection.

Laparoscopic versus Open stoma creation: A retrospective analysis.

OBJECTIVES: This study aimed to compare open stoma (OS) creation with laparoscopic stoma (LS) creation considering the operation time, blood loss, time of oral intake, and complications. We also compared multiport LS and single-incision laparoscopic stoma (SILS) creation. METHODS: We reviewed the demographic data, diagnosis, indications, operation time, blood loss, time of oral intake, operative procedure, and complications of 50 patients who underwent stoma creation between April 2014 and April 2016. RESULTS: The mean blood loss was significantly lower in the LS group (7.85±18.4 ml) than in the OS group (38.1±73.2 ml; P=0.02). There were no statistical differences between the groups in terms of the operation time (LS, 72.1±32.7 min; OS, 61.2±31.2 min; P=0.23) or time of oral intake (LS, 1.0±0 days; OS, 1.91±2.71 days; P=0.17). Peristomal skin problems occurred in 11 patients (47.8%) in the OS group and 5 patients (18.5%) in the LS group. There were no statistically significant differences between the SILS and multiport LS groups, considering the operation time, amount of bleeding, and time of oral intake. CONCLUSIONS: LS is comparable with OS in terms of operation time and time of oral intake and may cause lesser blood loss. Considering its advantages, LS is a useful approach for patients requiring biopsies or intra-abdominal inspection. SILS is a minimally invasive technique, suitable for patients in whom the stoma site is preoperatively decided.

Facility-Related Factors Influencing the Place of Death and Home Care Rates for End-Stage Cancer Patients.

BACKGROUND: In Japan, palliative home care is subject to increasing demand from patients. However, the number of deaths at home is still not as high as that of palliative home care users. OBJECTIVE: This study aimed to clarify factors influencing the place of death and home care rates, involving end-stage cancer patients targeted for palliative care by a general home-visit nursing agency. METHODS: A total of 87 patients who had used palliative home nursing care services provided by the study facility within a 6-year period after its opening were studied. RESULTS: The numbers of deaths at home supported by family physicians and those in hospital after readmission were 70 and 17, respectively. The numbers of deaths at home using services provided by the study facility and nurses belonging to it time-dependently increased, revealing a strong correlation between them. Furthermore, the place of death and home care rates were closely associated with the mean duration of home nursing services and home visits in collaboration with family physicians in charge. CONCLUSION: These results suggest that it may be possible to increase the rate of home care for end-stage cancer patients and meet their desires regarding the place of death through approaches to establish trust-based relationships with them and their families, such as strengthening manpower in home-visit nursing agencies and promoting collaboration between visiting nurses and family physicians in charge during home visits.

Going back to home to die: does it make a difference to patient survival?

BACKGROUND: Many patients wish to stay at home during the terminal stage of cancer. However, there is concern that medical care provided at home may negatively affect survival. This study therefore explored whether the survival duration differed between cancer patients who received inpatient care and those who received home care. METHODS: We retrospectively investigated the place of care/death and survival duration of 190 cancer patients after their referral to a palliative care consultation team in a Japanese general hospital between 2007 and 2012. The patients were classified into a hospital care group consisting of those who received palliative care in the hospital until death, and a home care group including patients who received palliative care at home from doctors in collaboration with the palliative care consultation team. Details of the place of care, survival duration, and patient characteristics (primary site, gender, age, history of chemotherapy, and performance status) were obtained from electronic medical records, and analyzed after propensity score matching in the place of care. RESULTS: Median survival adjusted for propensity score was significantly longer in the home care group (67.0 days, n = 69) than in the hospital care group (33.0 days, n = 69; P = 0.0013). Cox's proportional hazard analysis revealed that the place of care was a significant factor for survival following adjustment for covariates including performance status. CONCLUSIONS: This study suggests that the general concern that home care shortens the survival duration of patients is not based on evidence. A cohort study including more known prognostic factors is necessary to confirm the results.

Evaluation of A Novel Information-Sharing Instrument for Home-Based Palliative Care: A Feasibility Study.

AIM: To examine the feasibility and usefulness of a novel region-based pathway: the Regional Referral Clinical Pathway for Home-Based Palliative Care. METHOD: This was a feasibility study to evaluate the frequency of variances and the perceived usefulness of pathway using in-depth interviews. All patients with cancer referred to the palliative care team between 2011 and 2013 and received home care services were enrolled. RESULT: A total of 44 patients were analyzed, and pathway was completed in all the patients. The target outcome was achieved in 61.4% while some variances occurred in 54.5%. Nine categories were identified as the usefulness of the pathway, such as reviewing and sharing information and promoting communication, education, motivation, and relationships. CONCLUSION: This novel pathway is feasible and seems to be useful.

[Type 4 advanced gastric cancer responding to histological complete response after neoadjuvant S-1 combined with CDDP therapy-report of a case].

A 75-year-old man with type 4 advanced gastric cancer was referred to our hospital. We diagnosed the tumor as cStage III B(cT4a, cN2, cM0)gastric cancer. We selected neoadjuvant S-1 combined with CDDP therapy for him. After 2 courses of chemotherapy, the extension of the gastric wall improved. After an additional 2 courses of chemotherapy, the primary tumor revealed a partial response(PR), judged from a barium meal study and upper GI endoscopic findings, and a total gastrectomy with lymph node dissection was performed. The pathological specimens showed no cancer cells in the gastric wall and lymph nodes, so the histological effect was judged as Grade 3.

Mycotic abdominal aneurysm caused by campylobacter fetus: a case report for surgical management.

We report a rare case of mycotic abdominal aortic aneurysm associated with Campylobacter fetus. A 72-year-old male admitted to the hospital because of pain in the right lower quadrant with pyrexia. The enhanced abdominal computed tomography (CT) examination showed abdominal aortic aneurysm (AAA) measuring 50 mm in maximum diameter and a high-density area of soft tissue density from the right lateral wall to the anterior wall of the aorta. However, since the patient showed no significant signs of defervescence after antibiotics administration, so we performed emergency surgery on the patient based on the diagnosis of impending rupture of mycotic AAA. The aneurysm was resected in situ reconstruction using a bifurcated albumin-coated knitted Dacron graft was performed. The cultures of blood and aneurysmal wall grew Campylobacter fetus, allowing early diagnosis and appropriate surgical management in this case, and the patient is making satisfactory progress. This is the fifth report of mycotic AAA characterizing culture positive for Campylobacter fetus in blood and tissue culture of the aortic aneurysm wall.
