    Objectives: Bowel preparation is burdensome because of long cleansing times and large dose volumes of conventional polyethylene glycol (PEG) lavage solution Niflec® (Nif). MoviPrep (Mov) ® is a hyperosmolar preparation of PEG, electrolytes, and ascorbic acid; despite the smaller dose volume of 2 L, it can be challenging for many patients. We examined a more effective and acceptable bowel preparation method without compromising cleanliness and effectiveness, combining low-residue diet and laxative (Modified Brown Method) in Mov administered 1 day pre-colonoscopy.

    Methods: This multicenter, randomized, open-label, parallel-group comparative study, conducted at Hiroshima University Hospital and 7 affiliated hospitals in May 2015-March 2016, evaluated adherence to and effectiveness of Mov in bowel preparation. Participants (n=380) were allocated to receive 1 of 3 pre-colonoscopy regimens: Nif+Modified Brown Method (Group A), Mov+Modified Brown Method (Group B), or Mov+Laxative (Group C).

    Results: Total intake volume showed no significant difference among the groups. Bowel preparation time was significantly shorter in Group B (112.4±44.8 min, n=118) than in Groups A (131.3±59 min, n=105) and C (122.6±48.1 min, n=115). Sleep disturbance (37%) was significantly higher in Group B than Group A; distension (11%) was significantly lower in Group C than in Groups A and B (p<0.05, respectively). No severe adverse events occurred in any group.

    Conclusions: Mov+Modified Brown method provided significantly shorter bowel preparation time, with no significant difference in total intake volume among the regimens. Mov+Laxative yielded significantly less distension than the other groups, with bowel preparation equivalent to that of the Nif+Modified Brown method.

    Objectives: Stoma outlet obstruction (SOO) occurs with an incidence of approximately 40% after proctocolectomy for Ulcerative colitis (UC) with diverting ileostomy.

    This study aimed to identify the risk factors for SOO after proctocolectomy with diverting ileostomy for patients with UC.

    Methods: We reviewed the data of 68 patients with UC who underwent proctocolectomy and diverting ileostomy between April 2006 and September 2021. These cases were analyzed on the basis of clinicopathological and anatomical factors. SOO was defined as small bowel obstruction displaying symptoms of intestinal obstruction, such as abdominal distention, abdominal pain, insertion of a tube through the stoma.

    Results: The study included 38 (56%) men and 30 (44%) women with a median age of 42 years (range, 21-80). SOO categorized as at least Clavien-Dindo grade II occurred in 11 (16%) patients. Six patients required earlier stoma closure than scheduled. Compared with patients without SOO, patients with SOO had a significantly higher total steroid dose from the onset of UC to surgery (p = 0.02), a small amount of intraabdominal fat (p = 0.04), and a higher rate of laparoscopic surgery (p < 0.01).

    Conclusions: A high preoperative steroid dose, a small amount of intraabdominal fat and laparoscopic surgery were identified as risk factors for SOO. Early detection and treatment for SOO are important for patients at risk.

    Objectives: This study evaluates the safety and efficacy of laparoscopic ventral rectopexy (LVR) in nonagenarian patients with external rectal prolapse (ERP) compared to Delorme's procedure.

    Methods: We conducted a retrospective analysis of prospectively collected data, including nonagenarian patients who underwent either LVR or Delorme's procedure, comparing outcomes such as morbidity, length of hospital stay (LOS), and recurrence rates.

    Results: Between September 2009 and August 2023, 22 patients (median age 91, range 90−94 years) underwent LVR, while 12 patients (median age 91, range 90−96 years) received Delorme's procedure. Baseline characteristics, including sex ratio, parity, American Society of Anesthesiology grade, and Body Mass Index, did not significantly differ between the groups. LVR had a significantly longer operating time but lower blood loss than Delorme's procedure. Postoperative LOS was significantly shorter for LVR patients (median 1, range 1−3 days) compared to Delorme's procedure patients (median 2.5, range 1−13 days; P = 0.001). Notably, no significant morbidity occurred in the LVR group, while one case of delirium and another of solitary rectal ulcer syndrome were observed in the Delorme's procedure group. Recurrence rates were lower in the LVR group, with no recurrences during a median follow-up of 23 months (range 1−65 months), compared to one recurrence at 2 months during a median follow-up of 34 months (range 1−96 months) in the Delorme's procedure group.

    Conclusions: LVR is a safe and effective surgical option for nonagenarian ERP patients, showing favorable outcomes in terms of morbidity, LOS, and recurrence rates compared to Delorme's procedure.

    Objectives: Double incontinence (DI), which is the co-occurrence of fecal incontinence (FI) and urinary incontinence (UI), increases with age and has a greater negative impact on the quality of life (QOL) than either incontinence alone. We aimed to assess lower urinary tract symptoms (LUTS) in patients with FI to elucidate the prevalence and characteristics of DI.

    Methods: This study enrolled consecutive patients who visited our hospital with FI symptoms. FI was evaluated using the Cleveland Clinic Florida Fecal Incontinence Score (CCFIS). LUTS were assessed using the International Prostate Symptom Score (IPSS), QOL score (IPSS-QOL) and Overactive Bladder Symptom Score (OABSS).

    Results: This study evaluated 140 patients (96 women [mean age: 70.7 years] and 44 men [mean age: 74.4 years]). The mean IPSS was significantly higher in men than in women (12.0 vs. 7.5, p = 0.003). A positive correlation was found between IPSS and CCFIS in women (r = 0.256, p = 0.012) but not in men. For both sexes, the older group (aged ≥70 years) had higher OABSS scores and more urge UI instances than the younger group (aged ≤69 years). Of the 140 patients with FI, 78 (55.7%) had DI, and DI was more common in women than in men (63.5% vs. 38.6%, p = 0.006).

    Conclusions: The characteristics of LUTS and UI in patients with FI were comparable to those in the general population for both sexes; however, the prevalence of DI was much higher among patients with FI than that in the general population.

    Inflammatory myofibroblastic tumors (IMTs) are neoplastic lesions characterized by the proliferation of spindle cells with myofibroblastic features and lymphocyte infiltration. Primary lesions can develop in several locations but rarely arise in the colon as described herein. The present case was that of a 69-year-old woman who visited our hospital with complaints of bloody bowel discharge and a prolapsed mass from the anus. A 20-mm tumor was identified on visual and digital examination. Lower gastrointestinal endoscopy revealed a pedunculated, elevated lesion above the dentate line, which showed contrast enhancement on abdominal computed tomography. The patient was preoperatively diagnosed with an anal polyp, which was resected transanally. During the procedure, a mobile tumor coated by anal epithelium was observed at the 11 o'clock position above the dentate line. Deeper parts of the tumor were contiguous with the internal anal sphincter (IAS) muscle. Suspecting a neoplastic lesion, we resected the mass en bloc with part of the IAS. Tumor histopathology after surgery led to a final diagnosis of an IMT of the anus. IMT is difficult to diagnose preoperatively. No adjuvant therapy has been formally established; thus, an adequate surgical margin and close monitoring are essential.

    Although robotic rectal resections are now widely performed, there are few robotic suction tools that can be easily used by console surgeons. It can therefore be difficult to maintain a clear visual field in the pelvis when there is effusion and bleeding from either a highly advanced cancer or from preoperative cancer treatment. In this report, we introduce our unique surgical technique that uses a soft catheter with a small gauze ball attached, inserted through the assistant port. This simple and inexpensive "instrument" can be used by the console surgeon as a retractor as well as a reliable suction device to secure their view of the operative field in the pelvis. This technique can be used in a narrow surgical field and does not rely on an assistant surgeon, making it potentially applicable to all types of surgery.
