RESUMO
BACKGROUND: This study aimed to clarify the efficacy and safety of minimally invasive transabdominal surgery (MIS) with transperineal minimal invasive surgery (tpMIS) for sacrectomy in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of MIS with tpMIS for sacrectomies. Surgery was performed between February 2019 and May 2023. The median follow-up period was 27 months (5-46 months). RESULTS: Fifteen consecutive patients were included in this analysis. The diagnoses were as follows: recurrent rectal cancer, n = 11 (73%); primary rectal cancer, n = 3 (20%); and recurrent ovarian cancer, n = 1 (7%). Seven patients (47%) underwent pelvic exenteration with sacrectomy, six patients (40%) underwent abdominoperineal resection (APR) with sacrectomy, and two patients (13%) underwent tumor resection with sacrectomy. The median intraoperative blood loss was 235 ml (range 45-1320 ml). The postoperative complications (Clavien-Dindo grade ≥ 3a) were graded as follows: 3a, n = 6 (40%); 3b, n = 1 (7%); and ≥ 4, n = 0 (0%). Pathological examinations demonstrated that R0 was achieved in 13 patients (87%). During the follow-up period, two patients (13%) developed local re-recurrence due to recurrent cancer. The remaining 13 patients (87%) had no local disease. Fourteen patients (93%) survived. CONCLUSIONS: Although the patient cohort in this study is heterogeneous, MIS with tpMIS was associated with a very small amount of blood loss, a low incidence of severe postoperative complications, and an acceptable R0 resection rate. Further studies are needed to clarify the long-term oncological feasibility.

BACKGROUND: Surgical site infections (SSIs) are common complications after abdominal surgery. AIM: To compare which suture devices could reduce the incidence of incisional surgical site infections (SSIs) after gastrointestinal surgery using a systematic review and network meta-analysis. METHODS: The CENTRAL, PubMed, and ICHUSHI-Web databases were searched from January 1st, 2000, to December 31st, 2022, for randomized clinical trials (RCTs) comparing the incidence of incisional SSI after gastrointestinal surgery among patients treated with different surgical suture devices, including non-absorbable sutures, absorbable sutures, skin staplers, and tissue adhesives (last searched in August 23th, 2023). The risk of bias was assessed using the criteria of the Cochrane Handbook for Systematic Reviews of Interventions. To estimate the pooled odds ratios (ORs) for each comparison, a fixed-effect inverse-variance model based on the Mantel-Haenszel approach was employed. FINDINGS: A total of 18 RCTs with 5496 patients were included in this study. The overall SSIs in absorbable sutures were significantly lower than those in skin staplers (OR: 0.77; 95% confidence intervals (CI): 0.63-0.95) and non-absorbable sutures (OR: 0.62; 95% CI: 0.39-0.99), whereas SSIs in absorbable sutures were not significantly different from the SSIs in tissue adhesive. The highest P-score was 0.91 for absorbable sutures. A funnel plot for estimating the heterogeneity of the studies revealed that a publication bias would be minimal (Egger test, P = 0.271). CONCLUSION: This study showed that absorbable sutures reduced incisional SSIs in gastrointestinal surgical operations compared to any other suture devices.

BACKGROUNDS: Anastomotic leakage (AL) represents a major complication after rectal low anterior resection (LAR). Transanal drainage tube (TDT) placement offers a potential strategy for AL prevention; however, its efficacy and safety remain contentious. METHODS: A systematic review and meta-analysis were used to evaluate the influence of TDT subsequent to LAR as part of the revision of the surgical site infection prevention guidelines of the Japanese Society of Surgical Infectious Diseases (PROSPERO registration; CRD42023476655). We searched each database, and included randomized controlled trials (RCTs) and observational studies (OBSs) comparing TDT and non-TDT outcomes. The main outcome was AL. Data were independently extracted by three authors and random-effects models were implemented. RESULTS: A total of three RCTs and 18 OBSs were included. RCTs reported no significant difference in AL rate between the TDT and non-TDT groups [relative risk (RR): 0.69, 95% confidence interval (CI) 0.42-1.15]. OBSs reported that TDT reduced AL risk [odds ratio (OR): 0.45, 95% CI 0.31-0.64]. In the subgroup excluding diverting stoma (DS), TDT significantly lowered the AL rate in RCTs (RR: 0.57, 95% CI 0.33-0.99) and OBSs (OR: 0.41, 95% CI 0.27-0.62). Reoperation rates were significantly lower in the TDT without DS groups in both RCTs (RR: 0.26, 95% CI 0.07-0.94) and OBSs (OR: 0.40, 95% CI 0.24-0.66). TDT groups exhibited a higher anastomotic bleeding rate only in RCTs (RR: 4.28, 95% CI 2.14-8.54), while shorter hospital stays were observed in RCTs [standard mean difference (SMD): -0.44, 95% CI -0.65 to -0.23] and OBSs (SMD: -0.54, 95% CI -0.97 to -0.11) compared with the non-TDT group. CONCLUSIONS: A universal TDT placement cannot be recommended for all rectal LAR patients. Some patients may benefit from TDT, such as patients without DS creation. Further investigation is necessary to identify the specific beneficiaries.

The aim of this study was to conduct a systematic review and meta-analysis of the efficacy of fascial closure using antimicrobial-sutures specifically for the prevention of surgical site infections (SSIs) in gastrointestinal surgery, as part of the revision of the SSI prevention guidelines of the Japanese Society of Surgical Infectious Diseases (JSSI). We searched CENTRAL, PubMed and ICHUSHI-Web in May 2023, and included randomized controlled trials (RCTs) comparing antimicrobial-coated and non-coated sutures for fascial closure in gastrointestinal surgery (PROSPERO No. CRD42023430377). Three authors independently screened the RCTs. We assessed the risk of bias and the GRADE criteria for the extracted data. The primary outcome was incisional SSI and the secondary outcomes were abdominal wall dehiscence and the length of postoperative hospital stay. This study was supported partially by the JSSI. A total of 10 RCTs and 5396 patients were included. The use of antimicrobial-coated sutures significantly lowered the risk of incisional SSIs compared with non-coated suture (risk ratio: 0.79, 95% confidence intervals: 0.64-0.98). In subgroup analyses, antimicrobial-coated sutures reduced the risk of SSIs for open surgeries, and when monofilament sutures were used. Antimicrobial-coated sutures did not reduce the incidence of abdominal wall dehiscence and the length of hospital stay compared with non-coated sutures. The certainty of the evidence was rated as moderate according to the GRADE criteria, because of risk of bias. In conclusion, the use of antimicrobial-coated sutures for fascial closure in gastrointestinal surgery is associated with a significantly lower risk of SSI than non-coated sutures.
RESUMO
BACKGROUND: The purpose of this study was to clarify the efficacy and safety of transanal minimally invasive surgery (TAMIS) for total pelvic exenteration (TPE) in advanced primary and recurrent pelvic malignancies. METHODS: Using a prospectively collected database, we retrospectively analyzed the clinical, surgical, and pathological outcomes of TAMIS for TPE. Surgery was performed between September 2019 and April 2023. The median follow-up period was 22 months (2-45 months). RESULTS: Fifteen consecutive patients were included in this analysis M:F = 14:1 and median (range) age was 63 (36-74). Their diagnoses were as follows: primary rectal cancer (n = 5; 33%), recurrent rectal cancer (n = 4; 27%), primary anorectal cancer (n = 5; 33%), and gastrointestinal stromal tumor (n = 1; 7%). Bladder-sparing TPE was selected for two patients (13%). In nine of 15 patients (60%) the anal sphincter could be successfully preserved, five patients (33%) required combined resection of the internal iliac vessels, and two (13%) required rectus muscle flap reconstruction. The median operative time was 723 min (561-1082), and the median intraoperative blood loss was 195 ml (30-1520). The Clavien-Dindo classifications of the postoperative complications were as follows: grade 0-2 (n = 11; 73%); 3a (n = 3; 20%); 3b (n = 1; 7%); and ≥ 4 (n = 0; 0%). No cases of conversion to laparotomy or mortality were observed. The pathological results demonstrated that R0 was achieved in 14 patients (93%). CONCLUSIONS: The short-term outcomes of this initial experience proved that this novel approach is feasible for TPE, with low blood loss, acceptable postoperative complications, and a satisfactory R0 resection rate.

AIM: Precise biomarkers for predicting prognosis could help to identify high-risk Crohn's disease (CD) patients to facilitate better follow-up during the postoperative course. In this study, the primary aim is the identification of the most reliable nutrition marker that predicts surgical relapse in CD patients. METHOD: We first evaluated the predictive value of various nutrition markers for postoperative surgical relapse in CD patients and identified the advanced lung cancer inflammation index (ALI) as a promising biomarker. Then, we assessed the clinical significance of preoperative ALI in CD patients using two cohorts. RESULTS: Preoperative ALI showed the highest correlation with reoperation rate compared with other nutritional parameters in CD patients receiving surgical resection (sensitivity 53%, specificity 86%, area under the curve 0.71). Lower levels of preoperative ALI were significantly correlated with the presence of perianal disease. A lower level of preoperative ALI was an independent prognostic factor for reoperation rate after an intestinal resection (hazard ratio 3.37, 95% CI 1.38-10.12, P = 0.006), and the prognostic impact of preoperative ALI was successfully validated in an independent cohort using the same cut-off value. CONCLUSION: Preoperative ALI might be useful for postoperative management of CD patients.

Introduction Fistula formation around the ostomy site is a stoma-related complication often requiring surgical intervention. This complication may be caused by sutures or may develop as a complication of inflammatory bowel disease. Before conducting a clinical trial, we set out to investigate the safety of ostomy creation with fewer sutures using tissue adhesives in this pilot study. Methods Patients with inflammatory bowel disease who required surgery with ostomy creation at the Hyogo College of Medicine between January 2014 and December 2015 were enrolled. Safety was assessed by evaluating the incidence of stoma-related complications. Ostomy was restricted to loop ileostomy and was created with two sutures and tissue adhesives. Results A total of 14 patients were enrolled. Mean body mass index was 18.9 ± 2.0 kg/m2. There were no cases of ostomy retraction and no severe adverse events were observed. Conclusions This pilot study demonstrates that ostomy creation using tissue adhesives is safe. Although retraction and adverse events were not observed, even in patients with inflammatory bowel disease who generally exhibit delayed wound healing, the body mass index was extremely low in this series. This study does not strongly recommend ostomy creation with tissue adhesives; further studies are needed to clarify the efficacy and safety of the procedure.

We evaluated the clinical efficacy and safety of teicoplanin according to the pharmacokinetics (PK) therapeutic level achieved in patients with renal dysfunction. Target trough concentration (Cmin) was ≥15-30 µg/ml which has been recommended in patients with normal renal function. Adult patients (estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2)) who were treated by teicoplanin were included in the study. We adopted two types of regimen for the initial 3 days: the conventional regimen, and the enhanced loading regimen (10 mg/kg twice daily on the 1st day, followed by 6.7-10 mg/kg once daily for the 2nd and 3rd days]. Two hundred and eighty-eight patients were evaluated for safety, and 106 patients with methicillin-resistant Staphylococcus aureus (MRSA) infections were evaluated for clinical efficacy. A significantly higher success rate was obtained in patients who achieved the target initial Cmin compared with those that did not (75.0 % vs 50.0 %, p = 0.008). In a multivariate analysis, initial Cmin ≥15 µg/ml was an independent factor for clinical success (adjusted odds ratio: 4.20, 95 % confidence interval: 1.34-13.15). In patients with 15-30 µg/ml of maximal Cmin during therapy, nephrotoxicity occurred in 13.1 %, and hepatotoxicity in 2.6 %, and these incidences were not significantly higher compared with those patients with <15 µg/ml. In conclusion, achievement of Cmin of 15-30 µg/ml without delay was necessary to improve clinical outcomes for the treatment by teicoplanin in patients with renal dysfunction. Further investigation is required regarding the optimal loading regimen to achieve the therapeutic levels in those patients.

BACKGROUND: Data supporting active surveillance of meticillin-resistant Staphylococcus aureus (MRSA) for the prevention of postoperative infection remain controversial. AIM: To investigate the efficacy of MRSA screening in patients undergoing gastroenterological surgery. METHOD: Nasal carriage of MRSA was screened using a polymerase chain reaction (PCR) assay on two gastroenterological surgery wards (A and B). Occurrence of postoperative MRSA infection was analysed according to nasal MRSA carriage status (pre-operative carriage and postoperative acquisition). FINDINGS: The incidence of pre-operative MRSA carriage was 9.7% on Ward A and 4.3% on Ward B (P = 0.009). Postoperative nasal MRSA acquisition was confirmed in 16.2% and 6.0% of patients, respectively (P < 0.001). There was no significant difference in the incidence of MRSA surgical site infections (SSIs) between patients with and without pre-operative nasal colonization on either ward. On Ward A, where MRSA nasal acquisition was more common, the MRSA infection rate in patients with postoperative nasal acquisition was 26.8%, which was significantly higher than the rates in patients with pre-operative MRSA colonization and patients without colonization during hospitalization. Postoperative nasal MRSA acquisition was an independent factor associated with MRSA infection on both wards [Ward A: odds ratio (OR) 7.192, 95% confidence interval (CI) 2.981-17.352; Ward B: OR 5.761, 95% CI 1.429-23.220]. CONCLUSION: MRSA SSIs were prevented by a screening-based strategy in pre-operative MRSA carriers. Postoperative nasal acquisition was a significant factor affecting MRSA infection, and the effect of screening varied according to the incidence of postoperative MRSA acquisition on the ward.

AIMS: Increasing evidences suggest a similarity in the pathophysiological mechanisms of neuronal cell death in amyotrophic lateral sclerosis (ALS) and myofibre degeneration in sporadic inclusion body myositis (sIBM). The aim of this study is to elucidate the involvement of ALS-causing proteins in the pathophysiological mechanisms in sIBM. METHODS: Skeletal muscle biopsy specimens of five patients with sIBM, two with oculopharyngeal muscular dystrophy (OPMD), three with polymyositis (PM), three with dermatomyositis (DM), three with neurogenic muscular atrophy, and three healthy control subjects were examined. We analysed the expression and localization of familial ALS-causing proteins, including transactive response DNA binding protein-43 (TDP-43), fused in sarcoma/translocated in liposarcoma (FUS/TLS), Cu/Zn superoxide dismutase (SOD1) and optineurin (OPTN) by immunohistochemistry. RESULTS: TDP-43, OPTN and, to a lesser extent, FUS/TLS were more frequently accumulated in the cytoplasm in patients with sIBM and OPMD than in patients with PM, DM, neurogenic muscular atrophy, or healthy control subjects. SOD1 was accumulated in a small percentage of myofibres in patients with sIBM and OPMD, and to a very small extent in patients with PM and DM. Confocal microscopy imaging showed that TDP-43 proteins more often colocalized with OPTN than with FUS/TLS, p62 and phosphorylated Tau. CONCLUSIONS: These findings suggest that OPTN in cooperation with TDP-43 might be involved in the pathophysiological mechanisms of skeletal muscular degeneration in myopathy with rimmed vacuoles. Further investigation into these mechanisms is therefore warranted.

OBJECTIVE: To determine the antioxidant supplementation effect on accommodation among VDT users. DESIGN: A double blind randomized placebo controlled study. Registered under ClinicalTrials.gov Identifier No. NCT00877201. PARTICIPANTS AND CONTROLS: Fourty right eyes of 40 healthy VDT users (30 females, 10 males, mean age: 43.8±2.8 years, range: 40-49 years). 20 subjects (15 females, 5 males; mean age: 44.0±2.7 years, range: 40-49 years). METHODS: Subjects were required to take an antioxidant supplement, 20 age and sex matched subjects (15 females, 5 males; mean age: 43.6±3.1 years, range: 40-49 years) were required to take placebo medication for 4 weeks. RESULTS: The mean of the change in accommodation power was significantly higher in the group receiving antioxidant supplements (0.20±0.50 Diopter(D)) compared to the placebo group (-0.12±0.48(D)) (p<0.05). CONCLUSIONS: Antioxidant supplementation was observed to improve accommodation in Japanese Visual Display Terminal (VDT) Users.

We investigated the efficacy of lacrimal punctal occlusion surgery with a cautery device in patients with chronic GVHD (cGVHD)-related dry eye, with recanalization of puncta and recurrent punctal plug extrusion. A total of 23 puncta from 14 eyes of 10 patients with chronic GVHD (cGVHD)-related dry eye underwent punctual thermal cauterization with a high-temperature disposable cautery device. All patients were refractory to conventional treatment, including artificial tear eye drops, autologous serum eye drops and vitamin A eye drops, and had a history of recanalization and recurrent punctal plug extrusion. The effect of lacrimal punctal cauterization by thermal cautery device was evaluated by changes in subjective symptom scores, corrected distance visual acuity, Schirmer's test values, fluorescein staining scores, rose bengal staining scores, and tear-film break-up time before and 3 months after the surgery. Subjective symptom scores, Schirmer's test values, fluorescein and rose bengal scores, and tear-film break-up time improved significantly 3 months after the surgery. Recanalization of puncta was not observed in all the cases (0 of 14 eyes, 0%). Lacrimal punctal cauterization was effective with no recanalization and significant improvements in subjective symptoms and the ocular surface environment in cGVHD-related dry eye patients who had been refractory to conventional treatments.

OBJECTIVE: Familial amyloid polyneuropathy (FAP), which is a fatal disorder inherited in an autosomal dominant fashion, is characterized by systemic accumulation of polymerized transthyretin (TTR) in the peripheral nerves and systemic organs. Liver transplantation has become an accepted treatment of this disorder because it stops the major production of amyloidogenic TTR. However, improved survival of transplant patients compared with that of nontransplant patients has not been sufficiently demonstrated. This study investigated whether transplantation improved the long-term outcome of patients by comparing the survival of patients who had transplantations with that of patients who had not had transplantations. METHODS: Eighty consecutive patients with FAP Val30Met who visited Kumamoto University Hospital between January 1990 and December 2010 were studied. The transplant group consisted of 37 patients who had a partial hepatic graft via living donor transplantation in Japan or who underwent liver transplantation in Sweden, Australia, or the United States. The nontransplant group consisted of 43 patients with FAP. Survival was evaluated by using Kaplan-Meier analysis, and the difference in survival was examined via the log-rank test. RESULTS: The transplant group had prolonged survival (p < 0.001) compared with the nontransplant group. The estimated probability of survival at 10 years was 56.1% for the nontransplant group vs 100% for the transplant group. CONCLUSION: Liver transplantation should be considered as an effective treatment in clinical management of patients with FAP Val30Met. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that liver transplantation prolongs survival in patients with FAP Val30Met.

PURPOSE: To determine whether the incidence rate and severity of dry eye after hematopoietic stem cell transplantation varies with donor vs recipient gender. METHODS: We limited this study to patients received bone marrow transplantation (BMT). In all, 172 patients received BMT at Keio University School of Medicine between January 2000 and May 2007. Of them, 136 recipients who survived at least 70 days were studied prospectively. We classified the 136 patients according to the gender of the donor and the recipient (group I: female to female; group II: male to male; group III: male to female; group IV: female to male). The incidence and severity of chronic graft-vs-host disease-associated dry eye were determined for each group. The donor gender was masked when we assessed dry eye and calculate the incidence. RESULTS: The incidence of dry eye was 47.4% for group I, 37.5% for group II, 58.6% for group III, and 42.9% for group IV. The percentage of patients with severe dry eye was 44.4, 50.0, 35.3, and 77.8% respectively. There was a significant difference between the percent severe dry eye/total dry eye incidences in groups III and IV (P=0.0375) (odds ratio, 7.6; 95% confidence interval, 1.00-101.01). CONCLUSIONS: Close attention must be paid to the development of dry eye in cases of female to male BMTs, because the ratio of severe/total dry eye is more common in cases of female to male BMTs than in other gender combination.

STUDY DESIGN: Case study. OBJECTIVES: Subacute myelo-optico-neuropathy (SMON) is a severe neuro-degenerative disorder caused by poisoning due to over-dose and prolonged oral administration of clioquinol; this disorder was more frequent during 1957-1970. It is characterized by axonal degeneration and gliosis in the cervical gracile fasciculus. Recently, copper-deficient myelo-neuropathies presenting similar symptoms (that is, painful dysesthesia/paresthesia in the lower limbs, ataxia, spastic paraplegia, autonomic disorders and visual impairment) were reported. Magnetic resonance imaging (MRI) of these patients detected T2-weighted hyperintensities in the cervical spinal cord. An unbalanced zinc-copper metabolism was suggested as one of the candidate pathogenesis of clioquinol toxicity because of its metal-chelating ability. The aim of this study was to present MRI findings of old SMON patients and to compare them with those of current copper-deficient myelo-neuropathies. SETTING: Japan. METHODS: We conducted and analyzed cervical and brain MRIs of seven old SMON patients who contracted the disorder during the 1960s. Serum iron, magnesium, copper, zinc and ceruloplasmin levels were also measured. RESULTS: Cervical T2-weighted MRIs showed mild volume loss and faint hyperintensities in the dorsal columns, which might reflect residual gliosis. Brain fast fluid-attenuated inversion-recovery images and tractography were normal. Current levels of serum copper and zinc were within almost normal ranges. CONCLUSION: Although fainter, the abnormal T2 MRI signals we observed were similar to and occurred in the same locations as those reported in copper-deficient myelo-neuropathy patients. We suggest that these findings are useful to study the mechanism of clioquinol toxicity before using it to treat neurodegenerative diseases such as Alzheimer's disease.

The aim of this study was to confirm the effect of implementing a hospital-wide project for appropriate use of antimicrobial prophylaxis (AMP) to reduce the rate of antibiotic-resistant organisms. Fifteen different manuals for each surgical department have been simultaneously implemented since February 2007. Compliance rate was compared between pre- and postintervention periods (3 months for each period). As an effect of this intervention, we analyzed changes in the rates of Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus among organisms isolated postoperatively. The number of operations was 1,627 in both periods. Among patients whose surgeries were longer than 3 h in duration, 75% received an additional intraoperative antimicrobial dose in the postintervention period and 23% in the preintervention period (P < 0.001). Although most patients received postoperative AMP with an interval of q12 h in the preintervention period, 63% of the patients received AMP with an interval of q8 h in the postintervention period. The duration of AMP use was reduced from 2.4 ± 1.9 to 1.6 ± 1.5 days (P < 0.001). Forty-seven percent of patients discontinued AMP within 24 h and 81% within 48 h. Isolation rates of P. aeruginosa among all gram-negative organisms significantly decreased from 13% (68/538 patients) to 7.3% (37/509 patients) (P = 0.004). Execution of a hospital-wide project to promote the appropriate use of AMP, including shortening the duration of AMP use, was useful to decrease the rate of P. aeruginosa isolated postoperatively.

We evaluated ocular surface alterations in allogeneic hematopoietic stem cell transplantation (HSCT) recipients with or without chronic GVHD-related dry eye in a prospective study. Fifty eyes of 25 post-HSCT patients and 28 eyes of 14 age-matched healthy controls were included. Meibomian gland (MG) obstruction, tear evaporation rate, corneal sensitivity (CS), Schirmer test-I, tear break-up time (BUT) and ocular surface vital staining were examined. Conjunctival impression and brush cytology specimens were collected to evaluate the goblet cell density (GCD) and the inflammatory cell numbers. Obvious MG obstruction, decreased CS and enhanced tear evaporation rate were found in post-HSCT patients compared with normal controls. In addition, decreased conjunctival GCD, increased conjunctival squamous metaplasia and inflammatory cells were noted in cGVHD-related dry eyes compared with normal controls and post-HSCT without dry eye subjects. Furthermore, the conjunctival inflammatory cells were significantly higher in severe dry eyes compared with mild dry eyes (P=0.03). We found comprehensive ocular surface alteration in post-HSCT patients, regardless of whether they had cGVHD-related dry eye or not. The results suggest that the extent of inflammatory process seems to have a pivotal role in the outcome of the cGVHD-related dry eye.
