Toxic megacolon (TM) is a severe condition characterized by acute colonic dilation, with specific radiological and clinical signs. The multifactorial etiology of TM is primarily associated with inflammatory bowel disease and infections. However, TM remains a challenging complication due to its potential for rapid progression to life-threatening conditions. This report describes a rare case of TM in a 25-year-old male with a history of recurrent constipation and chronic cocaine consumption. Examination and imaging indicated acute intestinal obstruction with dilated colon segments and fecal impaction, necessitating an urgent laparotomy. Surgery revealed pan-colonic dilatation and sigmoid perforations, leading to a total colectomy and ileostomy. Chronic constipation, often perceived as benign, can escalate into a critical situation, possibly exacerbated by cocaine-induced muscle weakness and hypoxia. Evidence suggests that cocaine negatively affects the intestinal mucosa, potentially leading to ischemia. Chronic factors, including the use of enemas, may have contributed to megacolon development and perforation. Overall, this report underscores the critical elements of diagnosis and the importance of patients\' medical history, particularly those with unusual risk profiles. In addition, it highlights the need for further research to fully understand the implications of these cases.

BACKGROUND: Urgent abdominal colectomy is indicated for patients with fulminant Clostridioides difficile infection (CDI) when other medical therapies fail, yet mortality remains high. Fecal microbiota transplant is a less invasive alternative approach for patients with fulminant CDI. We report the 30-day complications of patients with fulminant CDI who underwent either abdominal colectomy, fecal microbiota transplantation (FMT), or FMT followed by abdominal colectomy (FMT-CO). Methods: We performed a single-center, retrospective case review of combined medical and surgical patients with CDI at a large academic medical center between 2008 and 2016. Cohorts were identified as patients with fulminant CDI who underwent total abdominal colectomy alone (CO), FMT alone (FMT), or FMT-CO. We analyzed patient demographics, history, comorbidities, clinical and laboratory variables, CDI severity scores, and mortality outcomes at 30 days. Results: We identified 5,150 patients with CDI at our center during the review period; 16 patients met the criteria for fulminant CDI and were included in this study, with four patients in the CO cohort, eight patients in the FMT cohort, and four patients in the FMT-CO cohort. Demographics and CDI severity scores were similar for all three groups, although the selected comorbidity profiles differed significantly among the three cohorts. The 30-day mortality rates for patients in the CO, FMT, and FMT-CO groups were 25%, 12.5%, and 25%, respectively. Conclusions: FMT is an alternative or adjunctive therapy to colectomy for patients with fulminant CDI that is not associated with increased mortality. Implementation of FMT protocols in clinical practice would be dependent on the availability of qualified transplant material and successful early identification of patients likely to benefit from FMT.

UNASSIGNED: Robotic surgery has been progressively implemented for colorectal procedures but is still limited for multiquadrant abdominal resections. The present study aims to describe our experience in robotic multiquadrant colorectal surgeries and provide a systematic review and meta-analysis of the literature investigating the outcomes of robotic total proctocolectomy (TPC), total colectomy (TC), subtotal colectomy (STC), or completion proctectomy (CP) compared to laparoscopy.
UNASSIGNED: At our institution 16 consecutive patients underwent a 2- or 3-stage totally robotic total proctocolectomy (TPC) with ileal pouch-anal anastomosis. A systematic review of the literature was performed to select studies on robotic and laparoscopic multiquadrant colorectal procedures. Meta-analyses were used to compare the two approaches.
UNASSIGNED: In our case series, 14/16 patients underwent a 2-stage robotic TPC for ulcerative colitis with a mean operative time of 271.42 (SD:37.95) minutes. No conversion occurred. Two patients developed postoperative complications. The mean hospital stay was 8.28 (SD:1.47) days with no readmissions. Mortality was nil. All patients underwent loop-ileostomy closure, and functional outcomes were satisfactory. The literature appraisal was based on 23 retrospective studies, including 736 robotic and 9,904 laparoscopic multiquadrant surgeries. In the robotic group, 36 patients underwent STC, 371 TC, 166 TPC, and 163 CP. Pooled data analysis showed that robotic TC and STC had a lower conversion rate (OR = 0.17;95% CI, 0.04-0.82; p = 0.03) than laparoscopic TC and STC. The robotic approach was associated with longer operative time for TC and STC (MD = 104.64;95% CI, 18.42-190.87; p = 0.02) and TPC and CP (MD = 38.8;95% CI, 18.7-59.06; p = 0.0002), with no differences for postoperative complications and hospital stay. Reports on urological outcomes, sexual dysfunction, and quality of life were missing.
UNASSIGNED: Our experience and the literature suggest that robotic multiquadrant colorectal surgery is safe and effective, with low morbidity and mortality rates. Nevertheless, the overall level of evidence is low, and functional outcomes of robotic approach remain largely unknown.

Atezolizumab is a programmed death-ligand 1 (PD-L1) targeted antibody that prevents the binding of PD-L1 to specific T-cell receptors, thereby increasing anticancer immunity. It has been regarded as a useful first-line treatment in patients with small-cell lung cancer with a more tolerable side effect profile than chemotherapeutic agents. However, few studies focusing on the severity of adverse effects from immune checkpoint inhibitors (ICPI) have been previously reported, particularly acute fulminant colitis requiring surgical invention. We report a case of fulminant colitis refractory to high dose corticosteroid treatment in a patient with known ulcerative colitis (UC) undergoing treatment for small-cell lung cancer (SCLC) with atezolizumab. The upregulation of PD-L1 expression in patients with ulcerative colitis may play a significant role in an imbalanced T-helper cell response creating a pro-inflammatory state. The use of ICPIs to treat SCLC has been reported to increase the risk of developing inflammatory colitis. Atezolizumab use in a patient with known inflammatory bowel disease (IBD) may predispose this population to a higher risk of developing severe inflammatory colitis. We present an unusual complication associated with medical intervention in an immunocompromised patient without an established pathophysiology. The suspicion of using ICPIs in patients with IBD as a potential cause for the development of fulminant colitis is relevant and essential in the diagnostic workup for this patient population complaining of significant gastrointestinal symptoms.

OBJECTIVE: This study primarily aimed to compare the long-term prognosis of patients who underwent total colectomy/proctocolectomy with or without mucosectomy to the dentate line for the diagnosis of familial adenomatous polyposis (FAP).
METHODS: Patients who underwent total colectomy/proctocolectomy for FAP between January 1979 and December 2020 and were followed up at Hamamatsu University Hospital were included in this study. Those who underwent total proctocolectomy with hand-sewn ileal pouch-anal anastomosis were defined as the mucosectomy group. Those who underwent total colectomy or total proctocolectomy using the stapled ileal pouch-anal anastomosis approach were defined as the no mucosectomy group.
RESULTS: A total of 61 individuals (37 families) were diagnosed during the surveillance period (median, 191 months). Between the mucosectomy (n = 24) and no mucosectomy groups (n = 34), metachronous rectal cancer was significantly more common in the no mucosectomy group (21% in no mucosectomy vs. 0% in mucosectomy, P = 0.02). Overall survival in the no mucosectomy group was worse than that in the mucosectomy group (84.5% in no mucosectomy vs. 100% in mucosectomy at 120 months, 81.1% vs. 90.0% at 240 months, 50.6% vs. 75.0% at 360 months, P = 0.09). Cox regression analysis revealed an independent effect of not performing mucosectomy on overall survival (P = 0.03).
CONCLUSIONS: Long-term surveillance revealed that colectomy or total proctocolectomy without mucosectomy had a negative impact on the overall survival of patients with FAP. Therefore, we recommend total proctocolectomy with mucosectomy, i.e., hand-sewn ileal pouch-anal anastomosis, for FAP.

BACKGROUND: The balance between quality of life and colorectal cancer risk in familial adenomatous polyposis (FAP) patients is of primary importance. A cut-off of less than 30 polyps under 1 cm of diameter in the rectum has been used as an indication for performing ileo-rectal anastomosis (IRA) in terms of lower rectal cancer risk. This study aimed to assess clinical and surgical features of FAP patients who developed cancer of the rectal stump.
METHODS: This retrospective study included all FAP patients who underwent total colectomy/IRA from 1977 to 2021 and developed subsequent rectal cancer. Patients\' features were reported using descriptive statistics by considering the overall case series and within pre-specified classes of age (<20, 20-30, and >30 years) at first surgery.
RESULTS: Among the 715 FAP patients, 47 (6.57%, 95% confidence interval: 4.87; 8.65) developed cancer in the rectal stump during follow-up. In total, 57.45% of the population were male and 38.30% were proband. The median interval between surgery and the occurrence of rectal cancer was 13 years. This interval was wider in the youngest group (p-value: 0.012) than the oldest ones. Twelve patients (25.53%) received an endoscopic or minimally invasive resection. Amongst them, 61.70% were Dukes stage A cancers.
CONCLUSIONS: There is a definite risk of rectal cancer after total colectomy/IRA; however, the time interval from the index procedure to cancer developing is long. Minimally invasive and endoscopic treatments should be the procedures of choice in patients with early stage cancers.

Volvulus of the colon is the third important reason for colon obstruction, which can occur in different parts of the colon for various reasons and can lead to ischemia and necrosis of the colon wall tissue. In this article, we are going to describe a simultaneous sigmoid and colon volvulus which was operated on with suspicion of sigmoid volvulus. A 72-year-old patient presented with suddenly severe generalized abdominal pain with a past medical history of inflammatory bowel disease (IBD) and prolonged constipation who underwent laparotomy for suspected colonic volvulus. During the operation, it was found that transverse colon volvulus occurred simultaneously with sigmoid colon volvulus with colon necrosis along its length. Therefore, a total colectomy with ileorectal anastomosis was performed. After one week, the patient was discharged from the surgical ward after tolerating feeding and with stable vital signs. The simultaneous transverse colon and sigmoid volvulus is a rare phenomenon, and there are several ways to diagnose and evaluate this situation. However, none of them can help us diagnose this disease. Unfortunately, no specific algorithm has been designed for the approach in this situation, and it all depends on the patient\'s condition. Simultaneous occurrence of the sigmoid and transverse colon can make a high-risk emergency condition that could threaten the patient\'s life. Therefore, paying attention to the patient\'s symptoms and patient\'s condition and clinical findings, with high accuracy and speed and subsequently selecting the best surgical technique, if surgery is necessary, and according to the finding during surgery, especially the extent of necrotic tissue, the most crucial issue in treating the patient.

Liver disease is a common manifestation of inflammatory bowel disease. Although less common than other hepatic manifestations, autoimmune hepatitis can be seen in patients with ulcerative colitis. One possible mechanism in the relationship between the two is through the leaky gut where defects in the colonic mucosal barrier increase exposure to gut-derived toxins and bacterial products leading to immune activation. We report two cases of autoimmune hepatitis with concomitant severe ulcerative colitis in which complete remission of autoimmune hepatitis was seen following total colectomy.

UNASSIGNED: Ehlers Danlos syndromes (EDS) are a group of genetic disorders, characterized by skin hyperelasticity, joint hyperlaxity and tissue weakness. Vascular EDS is rare and is differs from other types of EDS by an inconsistent acrogenic morphotype and the occurrence of severe digestive and vascular complications, which can be lifethreatening.
UNASSIGNED: We report the case of a 27-year-old man with a type IV vascular Ehlers-Danlos syndrome revealed by a colonic perforation after appendectomy for peritonitis secondary to appendicitis. The etiology of the perforation remained a challenge till a genetic research was carried out for COL3A1 gene mutation, which was positive in favor of vascular Ehlers Danlos disease. Then, a totalization of the colectomy with ileorectal anastomosis was performed.
UNASSIGNED: Vascular Ehlers Danlos syndrome (VEDS) is due to qualitative and quantitative abnormalities in the synthesis of type III collagen, which is a major constituent of the vessel wall, skin, joint capsules, uterus and gastrointestinal tract, particularly the colon. Colonic perforation, particularly sigmoidal perforation, is the most frequent complication in SEDV and most often precedes the molecular diagnosis. Colonic perforations are uncommon. The Hartmann procedure is a well-established surgical treatment modality, especially for emergency surgery. Given the iterative risk of colonic perforation and anastomotic leakage, preventive treatment by total colectomy with ileo-rectal anastomosis or definitive ileostomy is recommended by several authors.
UNASSIGNED: SEDV is a rare pathology with a difficult diagnosis. However, it should be keeped in mind when there is any spontaneous colonic perforation in the young people.

(1) Background: The aim of this study was to assess the outcomes for patients who underwent total colectomy (TC) as a part of surgery for ovarian cancer (OC). (2) Methods: We performed a retrospective analysis of 1636 OC patients. Residual disease (RD) was reported using Sugarbaker\'s completeness of cytoreduction score. (3) Results: Forty-two patients underwent TC during primary debulking surgery (PDS), and four and ten patients underwent TC during the interval debulking surgery (IDS) and secondary cytoreduction, respectively. The median overall survival (mOS) in OC patients following the PDS was 45.1 months in those with CC-0 (21%) resection, 11.1 months in those with CC-1 (45%) resection and 20.0 months in those with CC-2 (33%) resection (p = 0.28). Severe adverse events were reported in 18 patients (43%). In the IDS group, two patients survived more than 2 years after IDS and one patient died after 28.6 months. In the recurrent OC group, the mOS was 6.9 months. Patient age above 65 years was associated with a shortened overall survival (OS) and the presence of adverse events. (4) Conclusions: TC as a part of ultra-radical surgery for advanced OC results in high rates of optimal debulking. However, survival benefits were observed only in patients with no macroscopic disease.
