    Abstract Background: In patients with conjoined nerve roots, hemilaminectomy with sufficient exposure of the intervertebral foramen or lateral recess is required to prevent destabilization and ensure correct mobility of the lumbosacral spine. To the best of our knowledge, no case reports have detailed the long-term course of conjoined nerve roots after surgery.
    Case presentation: We report the case of a 51-year-old Japanese man with a conjoined nerve root. The main symptoms were acute low back pain, radiating pain, and right leg muscle weakness. Partial laminectomy was performed with adequate exposure to the conjoined nerve root. The symptoms completely resolved immediately after surgery. However, the same symptoms recurred 7 years postoperatively. The nerve root was compressed because of foraminal stenosis resulting from L5-S disc degeneration. L5-S transforaminal lumbar interbody fusion was performed on the contralateral side because of an immobile conjoined nerve root. At 44 months after the second surgery, the patient had no low back pain or radiating pain, and the muscle weakness in the right leg had improved.
    Conclusions: This is the first report of the long-term course of conjoined nerve root after partial laminectomy. When foraminal stenosis occurs after partial laminectomy, transforaminal lumbar interbody fusion from the contralateral side may be required because of an immobile conjoined nerve root.

    Abstract Objective: Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA.
    Patients and methods: We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7).
    Results: No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable.
    Conclusion: PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

    Abstract Introduction: Low serum amylase values are cross-sectionally associated with the prevalence of type 2 diabetes mellitus (T2DM) but have not been shown to be longitudinally associated with its incidence. This retrospective cohort (ie, historical cohort) study aimed to examine the association of previously lowered levels of serum amylase with incident T2DM.
    Research design and methods: Examined were 8316 individuals who had annual health examinations for 6 years (ie, 7 times) at the Toranomon Hospital Health Management Center. The trajectory of serum amylase as the study exposure was classified into two elements: (1) serum amylase level at entry and (2) change in serum amylase, which was expressed as the annual change rate. The annual change rate was calculated by dividing the change in the amylase values according to follow-up periods. Regression analyses were performed to examine the association between low and decreased levels of serum amylase and the incidence of T2DM.
    Results: Analyzed were 6917 individuals who had not developed T2DM within 1 year after cohort entry. T2DM thereafter occurred in 1021 patients. Cox regression indicated that the adjusted HR (95% CI) for incident T2DM for amylase ≤57 IU/L (quintile (Q) 1) was 0.97 (0.84 to 1.13) compared with amylase ≥58 IU/L (Q2-Q5). Logistic regression indicated that the adjusted OR (95% CI) for an annual change rate of amylase ≤-2.0% (Q1) vs ≥-1.9% (Q2-Q5) was 3.53 (3.00 to 4.16). The adjusted ORs were consistently significant throughout sensitivity analyses according to baseline amylase and the combination of age, body mass index, and hemoglobin A1c.
    Conclusions: Results showed that not low but previously decreased serum amylase was a risk factor for T2DM, suggesting the significance of periodic examinations of serum amylase values to detect individuals at high risk of T2DM.

    Abstract Background: When percutaneous transhepatic gallbladder drainage (PTGBD) is followed by laparoscopic cholecystectomy (LC), there is no consensus regarding whether the drainage tube should be preserved or removed before LC. We hypothesized that the surgical results of LC might differ between cases with PTGBD tube preservation versus removal. Here, we investigated how drainage tube preservation or removal affected the surgical outcome of LC.
    Methods: Using data from our previous multicenter study, we compared LC outcomes after PTGBD between patients with PTGBD tube preservation versus removal. This study included 208 patients who underwent LC over 12 days after PTGBD. In 83 cases, the PTGBD tube was preserved until LC, and in 125 cases, the tube was removed before LC. The results were verified by propensity score matching with 50 patients in each group.
    Results: Cases with tube preservation versus removal exhibited significantly longer surgery duration (174 ± 105 min vs 145 ± 61 min, P = .0118) and postoperative hospital stay (14 ± 16 days vs 7 ± 7 days, P < .0001), a significantly higher postoperative complication rate (13.2% vs 3.2%, P = .0061), and a marginally higher incidence of open conversion (12.0% vs 4.8%, P = .0547). Propensity score matching verified the inferior surgical outcomes in cases with tube preservation.
    Conclusions: These results imply that when LC is performed > 12 days after PTGBD, the surgical outcome may be inferior when the drainage tube is preserved rather than removed before LC.

    Abstract Introduction: Subtotal cholecystectomy (STC) has become recognized as a "bailout procedure" to prevent bile duct injury in patients undergoing laparoscopic cholecystectomy (LC). Predictors of conversion to STC have not been identified because LC difficulty varies based on pericholecystic inflammation. We analyzed data from patients enrolled in a previously performed multi-institutional retrospective study of the optimal timing of LC after gallbladder drainage for acute cholecystitis (AC). These patients presumably had a considerable degree of pericholecystic inflammation.
    Methods: In total, 347 patients who underwent LC after gallbladder drainage for AC were analyzed to examine preoperative and perioperative factors predicting conversion to STC.
    Results: Three hundred patients underwent total cholecystectomy (TC) and 47 underwent conversion to STC. Eastern Cooperative Oncology Group Performance Status (ECOG PS) (P < .01), severity of cholecystitis (P = .04), previous history of treatment for common bile duct stones (CBDS) (P < .01), and surgeon experience (P = .03) were significantly associated with conversion to STC. Logistic regression analyses showed that ECOG PS (odds ratio 0.2; P < .0001) and previous history of treatment for CBDS (odds ratio 0.37; P = .0073) were independent predictors of conversion to STC. Our predictive risk score using these two variables suggested that a score ≥2 could discriminate between TC and STC (P < .0001).
    Conclusion: Poor ECOG PS and previous history of treatment for CBDS were significantly associated with conversion to STC after gallbladder drainage for AC.

    Abstract Background: There is no consensus on the optimal timing of laparoscopic cholecystectomy (LC) after gallbladder drainage for acute cholecystitis (AC). To obtain evidence for a consensus, we investigated surgical outcomes of LC after gallbladder drainage with respect to the time elapsed from gallbladder drainage to surgery in a multi-institutional retrospective study.
    Methods: This study enrolled 347 patients who underwent LC after gallbladder drainage for AC at 15 institutions. Surgical outcome of LC was investigated in the cases based on the interval from gallbladder drainage to surgery.
    Results: The median interval from gallbladder drainage to surgery of the patients was 34 days, with a mean ± standard deviation of 58 ± 99 days. Patients were divided into four groups based on quartiles of the interval: Group A, cases with an interval of 1-12 days; Group B, cases with an interval of 13-34 days; Group C, cases with an interval of 35-73 days; and Group D, cases with an interval of ≥74 days. Surgical outcomes, which were evaluated with respect to intraoperative blood loss, operation time, postoperative hospital stay, rate of intraoperative accident, conversion from laparoscopic to open surgery, and postoperative complication, were worse in Group B than in the other groups. The finding was verified by propensity score-matched analysis.
    Conclusions: Surgical outcome of LC after gallbladder drainage for AC was inferior in Group B compared with the other groups. This finding could be useful for determining the optimal timing of LC after gallbladder drainage for AC.

    Abstract Aim: Minimally invasive liver resection (MILR) is considered a safe and feasible treatment for malignant liver tumors. However, few studies have investigated the surgical outcomes of MILR in patients with impaired liver function. Liver damage is used for consideration of hepatectomy. The aim of this study is to clarify the efficacy of MILR for patients with impaired liver function by using propensity score matching.
    Methods: Ninety-nine patients with liver damage B underwent hepatic resection were analyzed. The patients were divided into two groups, the MILR group (n = 24) and the open liver resection (OLR) group (n = 75). After matching of a propensity score, we compared clinicopathological features and surgical outcomes.
    Results: After matching, 36 patients (18 patients from each group) were selected and the patients' characteristics and tumor characteristics were not significantly different between the two groups. Blood loss (P = 0.0163) and complication rate (P = 0.0162) were significantly decreased in the MILR group. Complications were observed in eight patients, comprising one patient in the MILR group and seven patients in the OLR group. The postoperative hospital stay was significantly shortened in the MILR group (P = 0.0118).
    Conclusion: Minimally invasive liver resection might be effective for patients with impaired liver function. It reduces surgical complications and consequently shortens hospitalization time.

    Abstract Aim: The aim of this study was to investigate the therapeutic potential of sodium glucose cotransporter 2 inhibitor (SGLT2I) as an effective therapeutic option for non-alcoholic fatty liver disease (NAFLD).
    Methods: In this prospective study, nine patients with NAFLD complicated by type 2 diabetes mellitus (DM), were introduced to the regimen of canagliflozin 100 mg once daily for 24 weeks and were evaluated by liver histology at pretreatment and at 24 weeks after the start of treatment. The primary outcome was histological improvement, defined as a decrease in NAFLD activity score of one point or more without worsening in fibrosis stage. Glucose metabolism was evaluated based on the meal tolerance test. The usefulness of extracellular and exosome microRNA-122 (miR-122) as early predictors of histological improvement was investigated.
    Results: All of the nine patients achieved histological improvement. Scores of steatosis, lobular inflammation, ballooning, and fibrosis stage decreased by 78%, 33%, 22%, and 33% at 24 weeks compared to the pretreatment, respectively. Six patients showed improvement in insulin resistance, and the other three patients showed partial improvement of insulin secretion function. Six patients, who showed a decrease in both extracellular and exosome miR-122 ratios (the ratio of miR-122 levels at 1 day after treatment to that at baseline), showed histological improvement. Furthermore, one patient, who showed a decrease in exosome miR-122 ratios regardless of the increase in extracellular miR-122 ratios, also showed decreases in NAFLD activity score and fibrosis stage.
    Conclusion: A prospective study showed that SGLT2I for NAFLD complicated by DM improved histological features in connection with glucose metabolism. This trial was registered as clinical trial UMIN000018166.

    Abstract Solid serous cystadenoma of the pancreas is the rarest subtype of serous cystadenoma. Cystic structures are difficult to recognize by imaging studies. In the clinical setting, it is crucial to discriminate a solid serious cystadenoma from other solid pancreatic tumors. The present study reported a case of solid serous cystadenoma in which the magnetic resonance cholangiopancreatography (MRCP) findings were useful for diagnosis and decision-making regarding the surgical strategy, with a review of the previous reports of solid serous cystadenoma. A 50-year-old woman was referred to our hospital for investigation of a pancreatic body mass. A 2-cm hypervascular solid tumor was revealed by computed tomography. No typical radiological imaging findings of small cysts were detected, such as a honeycomb structure, and an adequate specimen could not be gained by biopsy under endoscopic ultrasonography. However, the tumor showed high intensity on MRCP, suggesting its cystic nature. A solid serous cystadenoma was suspected based on these radiological findings, and middle segment pancreatectomy was performed as a function-preserving surgery. The histological findings were compatible with a solid serous cystadenoma. In conclusion, MRCP imaging may be helpful for diagnosis and decision-making regarding the most appropriate surgical method for solid serous cystadenomas.
