Slow transit constipation (STC) has traditionally been considered as a functional disorder. However, evidence is accumulating that suggests that most of the motility alterations in STC might be of a neuropathic etiology. If the patient does not meet the diagnosis of pelvic outlet obstruction and poorly response to conservative treatment, surgical intervention with subtotal colectomy may be effective. The most unwanted complication of the procedure is anastomotic leakage, however, preservation of the superior rectal artery (SRA) may reduce its incidence. To evaluate the preservation of the SRA in laparoscopically assisted subtotal colectomy with ileorectal anastomosis in STC patients. This was a single-center retrospective observational study. STC was diagnosed after a series of examinations which included a colonic transit test, anal manometry, a balloon expulsion test, and a barium enema. Eligible patients underwent laparoscopically assisted total colectomy with ileorectal anastomosis and were examined between January 2016 and January 2018. The operation time, blood loss, time to first flatus, length of hospital days, and incidence of minor or major complications were recorded. A total of 32 patients (mean age, 42.6 years) who had received laparoscopic assisted subtotal colectomy with ileorectal artery anastomosis and preservation of the SRA. All patients were diagnosed with STC after a series of examinations. The mean operative time was 151 min and the mean blood loss was 119 mL. The mean day of first time to flatus was 3.0 d, and the mean hospital stay was 10.6 d. There were no any patients conversions to laparotomy. Post-operative minor complications including 1 wound infection and 1 case of ileus. There was no surgical mortality. No anastomosis leakage was noted in any of the patients. Laparoscopically assisted subtotal colectomy with ileorectal anastomosis and preservation of the SRA can significantly improve bowel function with careful patient selection. Sparing the SRA may protect against anastomosis leakage.

BACKGROUND Appendiceal mucinous neoplasms (AMNs), although not classified as rare, are relatively uncommon tumors most often discovered incidentally during colorectal surgery. Accurate identification of AMNs is difficult due to non-specific symptoms, overlapping tumor markers with other conditions, and the potential for misdiagnosis. This underscores the urgent need for precision in diagnosis to prevent severe complications. CASE SUMMARY This case report describes the unexpected discovery and treatment of a low-grade AMN (LAMN) in a 74-year-old man undergoing laparoscopic hemicolectomy for transverse colon adenocarcinoma (AC). Preoperatively, non-specific gastrointestinal symptoms and elevated tumor markers masked the presence of AMN. The tumor, presumed to be an AMN peritoneal cyst intraoperatively, was confirmed as LAMN through histopathological examination. The neoplasm exhibited mucin accumulation and a distinct immunohistochemical profile: Positive for Homeobox protein CDX-2 , Cytokeratin 20, special AT-rich sequence-binding protein 2, and Mucin 2 but negative for cytokeratin 7 and Paired box gene 8. This profile aids in distinguishing appendiceal and ovarian mucinous tumors. Postoperative recovery was uncomplicated, and the patient initiated adjuvant chemotherapy for the colon AC. CONCLUSION This case highlights the diagnostic complexity of AMNs, emphasizing the need for vigilant identification to avert potential complications, such as pseudomyxoma peritonei.

Anal stenosis is a rare but frustrating condition that usually occurs as a complication of hemorrhoidectomy. The severity of anal stenosis can be classified into three categories: mild, moderate, and severe. There are two main surgical treatments for this condition: scar revision surgery and anoplasty; however, no studies have compared these two approaches, and it remains unclear which is preferrable for stenoses of different severities. To compare the outcomes of scar revision surgery and double diamond-shaped flap anoplasty. Patients with mild, moderate, or severe anal stenosis following hemorrhoidectomy procedures who were treated with either scar revision surgery or double diamond-shaped flap anoplasty at our institution between January 2010 and December 2015 were investigated and compared. The severity of stenosis was determined via anal examination performed digitally or using a Hill-Ferguson retractor. The explored patient characteristics included age, sex, preoperative severity of anal stenosis, preoperative symptoms, and preoperative adjuvant therapy; moreover, their postoperative quality of life was measured using a 10-point scale. Patients underwent proctologic follow-up examinations one, two, and four weeks after surgery. We analyzed 60 consecutive patients, including 36 men (60%) and 24 women (40%). The mean operative time for scar revision surgery was significantly shorter than that for double diamond-shaped flap anoplasty (10.14 ± 2.31 [range: 7-15] min vs 21.62 ± 4.68 [range: 15-31] min; P < 0.001). The average of length of hospital stay was also significantly shorter after scar revision surgery than after anoplasty (2.1 ± 0.3 vs 2.9 ± 0.4 d; P < 0.001). Postoperative satisfaction was categorized into four groups: 45 patients (75%) reported excellent satisfaction (scores of 8-10), 13 (21.7%) reported good satisfaction (scores of 6-7), two (3.3%) had no change in satisfaction (scores of 3-5), and none (0%) had scores indicating poor satisfaction (1-2). As such, most patients were satisfied with their quality of life after surgery other than the two who noticed no difference due owing to the fact that they experienced recurrences. Scar revision surgery may be preferable for mild anal stenosis upon conservative treatment failure. Anoplasty is unavoidable for moderate or severe stenosis, where cicatrized tissue is extensive.

Plasma cell neoplasms are characterized by dysregulated proliferation of mature B cells, which can present with either single (solitary plasmacytoma) or systemic (multiple myeloma (MM)) involvement. MM with extramedullary plasmacytoma (EMP) is a rare disease that accounts for approximately 3–5% of all plasmacytomas. EMP with gastrointestinal (GI) system involvement is an even rarer entity, accounting for <1% of MM cases. We present a case of aggressive MM with EMP invading the duodenum, initially presented with massive upper GI hemorrhage and small bowel obstruction. A 67-year-old woman was admitted to our hospital owing to a lack of either gas or feces passage for 3 days. Abdominal distention and vomit with a high coffee ground content were observed for 24 h. The patient’s condition was initially diagnosed as small bowel obstruction, upper gastrointestinal bleeding, severe anemia, acute renal failure, and hypercalcemia. Furthermore, an analysis of immunoelectrophoresis in the blood, bone marrow aspiration, and tissue biopsy supported the diagnosis of MM and EMP invading the duodenum, upper GI hemorrhage, and small bowel obstruction. Our study provided the possible involvement of MM and EMP in the differential diagnosis of patients with unexplained GI hemorrhage and small bowel obstruction. A thorough review of the literature regarding the association between MM, GI hemorrhage, and small bowel obstruction is presented in this study.

Giant inguinoscrotal hernias are huge inguinal hernias that extend below the midpoint of the inner thigh in the standing posture. Giant inguinoscrotal hernias are rare in developed countries because of their better medical resources and early treatment. However, they can develop in patients who refuse surgery or ignore their condition. Intervention is inevitable because strangulation and organ perforation can occur, leading to peritonitis and sepsis. Common surgical approaches include open abdominal and inguinal approaches or a combination of both. We present the case of a 73-year-old man who visited our emergency department with a huge mass in his left scrotum and septic complications. Abdominal computed tomography revealed a large left inguinoscrotal hernia that contained small bowel loops and the colon. Emergency surgical intervention was performed immediately because intestinal strangulation was highly suspected. The operative repair was performed using a combination of mini-exploratory laparotomy and the inguinal approach. The incarcerated organs, which included the ileum and sigmoid colon, had relatively good intestinal perfusion without perforation or ischemic changes. They were successfully reduced into the abdomen, and bowel resection was not necessary. A tension-free prosthetic mesh was used for the hernia repair. Two weeks after the initial surgery, and with adequate antimicrobial therapy, the patient recovered and was discharged from our hospital. No evidence of hernia relapse was noted during the outpatient follow-up examination 3 mo after surgery. Emergency surgery involving combined mini-exploratory laparotomy and the inguinal approach should be performed for serious incarcerated giant inguinoscrotal hernias.

Intestinal intussusception is relatively rare in adults and accounts for approximately 5% of intestinal obstruction. Intussusception is classified into subtypes according to the location, including ileoileal, ileocolic, ileo-ileocolic, colo-colic, jejuno-ileal, or jejuno-jejunal; the ileocolic type being the most common. However, intussusception of a combination of different subtypes has rarely been reported in the available literature. Abdominal computed tomography (CT) is the most accurate tool to evaluate intestinal intussusception. The pathological lead point in the intestine typically results in adult intussusception. Surgical intervention is usually adopted in cases of adult intussusception due to a high incidence of underlying bowel malignancy. An inflammatory fibroid polyp (IFP) is one of the uncommon benign neoplasms of the gastrointestinal (GI) system, which can result in intestinal intussusception. Herein, we present a case of a 50-year-old female with combined ileoileal and ileocolic intussusception, which was initially diagnosed by abdominal CT. Therefore, laparoscopic right hemicolectomy surgery was performed, confirming the final diagnosis as ileoileal and ileocolic intussusception secondary to IFP.
