The American Society of Colon and Rectal Surgeons Clinical Practice Guidelines for the Management of Colonic Volvulus and Acute Colonic Pseudo-Obstruction

Ultrasound imaging of bowel obstruction in infants and children

We review the etiologies of bowel obstruction in infants and children that can be identified on ultrasound (US) including perforated appendicitis, intussusception, foreign body ingestion, colonic volvulus, intra-abdominal mass lesions, internal hernia, and stricturing inflammatory bowel disease. US can potentially identify the cause of bowel obstruction in these age groups, without the need for additional cross-sectional imaging, and can aid in patient management including interventional and surgical planning. Hence, it is important to be familiar with the sonographic imaging findings of bowel obstruction in infants and children.

Severe gastrointestinal problems in Duchenne muscular dystrophy: A case series

Due to improved supportive care, survival of patients with Duchenne muscular dystrophy (DMD) has increased significantly. Consequently, new challenges emerge in adult patients with DMD. In clinical practice we increasingly see patients with serious, even life-threatening, gastrointestinal (GI) problems in advanced disease stages. Little is known about the longitudinal course of GI problems and the appropriate management. We present a case-series of six adult patients with DMD with (recurrent) GI problems that required hospital admission. The most prevalent reported serious GI symptoms were gastrointestinal pseudo-obstruction, (sub)ileus and gastric dilatation. Besides, an overview is presented of the therapeutic options for GI problems in DMD. The current study provides insight in possible treatment options, however, there is a clear need for more research and an integral guideline on treatment of GI problems in adult patients with DMD in order to reduce associated morbidity and mortality.

Sigmoid and cecum colon volvulus: a case report

INTRODUCTION

Colon volvulus is the twisting of a segment of colon on its mesenteric axis, which can lead to the obstruction of the lumen and the blood supply. Colon volvulus is common in "volvulus belt" countries and can involve the sigmoid (60-70%) and cecum (25-40%).

CASE PRESENTATION

We report a case of a 47-year-old male, Alawites, who presented with bowel obstruction and dilated abdomen without any specific abdominal pain. Abdominal laparotomy showed both sigmoid and cecum volvulus with no signs of perforation or ischemia.

DISCUSSION AND CONCLUSION

One of the possible risk factors of sigmoid colon volvulus is the length of the rectum and sigmoid, while mobile cecum is considered as a possible reason for cecum volvulus. The management remains controversial and is specific for every case, depending mainly on the vitality of the colonic walls and the general condition of the patient.

Laparoscopic redo surgery for sigmoid volvulus following laparoscopic sigmoidectomy

BACKGROUND

Sigmoid volvulus (SV) is an acute abdominal condition characterized by torsion of the sigmoid colon around the mesentery, and often results in intestinal obstruction that may progress to bowel ischemia, necrosis, or perforation. Although SV commonly occurs due to predisposing factors like anatomic variations, age-related motility disorders, chronic constipation, and neurologic diseases, its incidence following sigmoid colon cancer surgery has rarely been reported. Herein, we report a rare case of recurrent SV following laparoscopic sigmoidectomy, which was successfully treated by laparoscopic redo surgery.

CASE PRESENTATION

The patient was a 77-year-old man who had previously undergone laparoscopic sigmoidectomy for sigmoid colon cancer. Sixteen months postoperatively, he developed an incisional hernia at the umbilical site, which was treated with a laparoscopic repair using an intraperitoneal onlay mesh. After the hernia surgery, the patient had no anastomotic leakage or stenosis on regular follow-ups. However, 65 months after the first surgery, he presented with abdominal pain and distension. A computed tomography revealed that the remnant sigmoid colon was distended in a twisting manner around the anastomosis, leading to the diagnosis of SV. Although endoscopic de-torsion was successful, the SV recurred 2 months later, requiring elective laparoscopic redo surgery. The procedure involved resection of the sigmoid colon including the prior anastomosis with a left pararectal incision and DST re-anastomosis using a 25-mm circular stapler. The operation lasted 165 min with minimal bleeding and no complications. The postoperative course was uneventful. Pathological analysis confirmed fibrosis without malignancy. The patient remains well without recurrence of SV and anastomotic stenosis more than 5 years after surgery.

CONCLUSION

SV following sigmoid colon cancer surgery has rarely been reported. This case illustrates the potential need for prophylaxis against postoperative SV, especially in patients with long sigmoid colon undergoing laparoscopic surgery for colorectal cancer. Further, laparoscopic redo surgery following initial laparoscopic surgery for colorectal cancer can be performed with minimal invasiveness, especially if patient selection is properly managed.

Acute colonic pseudo-obstruction: a retrospective review of the surgical outcomes

PURPOSE

Limited data exist regarding the surgical outcomes of acute colonic pseudo-obstruction (ACPO), commonly referred to as Ogilvie syndrome, in modern clinical practice. The prevailing belief is that surgery should be avoided due to previously reported high mortality rates. We aimed to describe the surgical results of ACPO treated within our institution.

METHODS

Our prospectively maintained colorectal surgery registry was queried for patients diagnosed with ACPO, who underwent surgery between 2009 and 2022. Postoperative complications were graded according to Clavien-Dindo (CD) classification. The primary outcome was postoperative mortality.

RESULTS

A total of 32 patients who underwent surgery for ACPO were identified. Overall, nonoperative therapy was initially administered to 21 patients (65.6%). The surgeries performed included total abdominal colectomy (15, 43.1%), ascending colectomy with end ileostomy (8, 25%), transverse colostomy (5, 15.6%), ileostomy and transverse colostomy (3, 9.4%), and Hartmann's operation (1, 3.1%). Severe postoperative complications (CD grade 3 or 4) occurred in five patients (15.6%). No recurrence of ACPO was observed and no patient required reoperation. The average postoperative length of stay was 14.5 days, 30-day mortality was 6.3% (n = 2), and 90-day mortality was 15.6% (n = 5) due to complications of underlying comorbidities.

CONCLUSIONS

Surgical treatment was effective for patients with ACPO refractory to medical therapy or presenting with acute complications. Although postoperative complications were frequent, both the 30- and 90-day mortality rates were lower than previously documented in the literature. Further investigations are warranted to determine the optimal surgical strategy, which may involve total or segmental colectomy, or diversion alone without resection.

Patience is key: Association of surgical timing with clinical outcomes in elderly patients with sigmoid volvulus

BACKGROUND

Current guidelines for sigmoid volvulus recommend endoscopy as a first line of treatment for decompression, followed by colectomy as early as possible. Timing of the latter varies greatly. This study compared early (≤2 days) versus delayed (>2 days) sigmoid colectomy.

METHODS

2016-2019 NRD database was queried to identify patients aged ≥65 years admitted for sigmoid volvulus who underwent sequential endoscopic decompression and sigmoid colectomy. Outcomes included mortality, complications, hospital length of stay, readmissions, and hospital costs.

RESULTS

842 patients were included, of which 409 (48.6 ​%) underwent delayed sigmoid colectomy. Delayed sigmoid colectomy was associated with reduced cardiac complications (1.1 ​% vs 0.0 ​%, p ​= ​0.045), reduced ostomy rate (38.3 ​% vs 29.4 ​%, p ​= ​0.013), an increased overall length of stay (12 days vs 8 days, p ​< ​0.001) and increased overall costs (27,764 dollar vs. 24,472 dollar, p ​< ​0.001).

CONCLUSION

In geriatric patient with sigmoid volvulus, delayed surgical resection after decompression is associated with reduced cardiac complications and reduced ostomy rate, while increasing overall hospital length of stay and costs.

A Case of Acute Colonic Pseudo-Obstruction and Anastomotic Leakage After Sigmoidectomy for Sigmoid Volvulus

Acute colonic pseudo-obstruction (ACPO) is characterized by significant colonic distension without a mechanical obstruction. We present a case of an 83-year-old male who developed ACPO following laparoscopic surgery for sigmoid volvulus. This report details the patient's postoperative journey, highlighting the diagnostic and management challenges encountered. Despite various medical interventions, the patient's condition necessitated further surgical attention due to complications. This case underscores the importance of early diagnosis and aggressive management in ACPO to prevent life-threatening consequences and improve patient outcomes.

Restoration of intestinal continuity following emergency sigmoid colectomy for sigmoid volvulus: An American College of Surgeons National Surgical Quality Improvement Program analysis using coarsened exact matching

BACKGROUND

There is limited data to guide decision-making between performing a primary anastomosis and fashioning an end colostomy following emergency sigmoid colectomy for patients with sigmoid volvulus. The aim of this study was to compare the outcomes of these two approaches.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2006 to 2021 was retrospectively analyzed. Missing data were multiply imputed, and coarsened exact matching was performed to generate matched cohorts. Rates of major complications and other postoperative outcomes were evaluated among patients who had a primary anastomosis as compared with matched controls who had an end colostomy following emergency sigmoid colectomy.

RESULTS

Overall, 4041 patients who had a primary anastomosis and 1240 who had an end colostomy met the inclusion criteria. After multiple imputation and coarsened exact matching, 895 patients who had a primary anastomosis had a matched control. The rate of major complications was lower in patients who had an end colostomy (33.2% vs. 36.7%), but this difference was not statistically significant (OR 0.86, 95% CI 0.70-1.05). Results were similar in subgroup analyses of higher-risk patients. There were no significant differences in overall complication rate, mortality, length of hospital stay, or readmission rate. Patients with a colostomy were more likely to be discharged to a care facility (OR 1.35, 95% CI 1.09-1.67).

CONCLUSION

Differences in rates of major complications and many other outcomes after primary anastomosis as compared with end colostomy were not statistically significant following emergency sigmoid colectomy for sigmoid volvulus.

Acute colonic pseudo-obstruction post-cesarean section is not a benign entity: A case series and review of the literature

Acute colonic pseudo-obstruction (ACPO) is an infrequent occurrence after cesarean section. Anecdotal evidence suggests that the clinical course of ACPO in the obstetric setting is different to that seen in non-pregnant adult patients with ACPO secondary to alternative causes, such as systemic illnesses, the use of certain medications, and after non-abdominal surgery. The risk of progression to ischemia and perforation, as well as the need for emergency surgery, appears to be higher after cesarean section. Here we describe the clinical course of ACPO in four patients after cesarean section from our institution, followed by a review of the literature and a discussion of the important issues surrounding this condition in the postpartum time period. The findings from our cohort of patients and the reports from the medical literature support a hands-on combined approach from a group of specialists including obstetricians, surgeons, radiologists, and enterostomal therapists. Immediate imaging followed by regular observation is mandatory for any patient being managed conservatively. Early use of endoscopic decompression should be considered for patients who are not resolving with a conservative approach. Clinical signs of peritonism or radiological signs of ischemia or perforation in patients with ACPO mandate immediate surgical intervention. Appropriate postoperative care is necessary to deal with the complex physiological and psychological consequences of emergency surgery and potential stoma formation so soon after cesarean section.

A case of acute colonic pseudo-obstruction, sigmoid volvulus, and massive pneumoperitoneum in a young female patient

INTRODUCTION AND IMPORTANCE

Acute colonic pseudo-obstruction (ACPO) is an uncommon phenomenon that is especially rare in young patients and can result in bowl ischemia and perforation if left untreated. Furthermore, pneumoperitoneum is almost always a concerning imaging finding and in the context of recent colonic resection may be a sign of anastomotic leakage.

CASE PRESENTATION

We describe a case of a young female patient with postpartum ACPO who subsequently underwent a hemicolectomy with colorectal anastomosis. The patient's hospital course was complicated by massive postoperative pneumoperitoneum that resulted in resection of the anastomosis and creation of an end colostomy. However, despite this measure, there was recurrent pneumoperitoneum on cross-sectional imaging 36 h later. This was treated non-operatively and the remainder of their hospital course was uneventful.

CLINICAL DISCUSSION

A potential etiology for ACPO during pregnancy may be due to compression of parasympathetic plexus nerves by the gravid uterus. Idiopathic pneumoperitoneum has been documented on a number of occasions, though this is generally in older patients. It can present with signs of peritonitis or can be asymptomatic. Simultaneous pneumothorax and pneumoperitoneum is rare and may be due to the transmission of air from the peritoneum to the mediastinum and thorax. The pneumoperitoneum itself may be due the air leakage through the significantly distended colon into the peritoneum.

CONCLUSION

The combination of ACPO following pregnancy and associated pneumothorax, pneumomediastinum, and recurrent pneumoperitoneum suggest a communicating defect between the thoracic, mediastinal, and peritoneal cavities. Furthermore, the possibility of underlying colonic dysmotility should be considered prior to the restoration of large bowel continuity.

Management of acute colonic pseudo-obstruction: opportunities to improve care?

BACKGROUND

Acute colonic pseudo-obstruction (ACPO) is a functional bowel obstruction characterised by colonic dilatation in the absence of mechanical obstruction on imaging. Complications include bowel ischaemia, perforation and death. The aim of this study was to explore outcomes for patients treated for ACPO and to assess adherence to current ACPO treatment guidelines.

METHODS

This is a retrospective service evaluation and included patients with a diagnosis of ACPO between 1 March 2018 and 31 March 2023. Process measures were identified following discussion with the clinical team from published guidance. Patients were identified using clinical coding and radiological text reports. Cases were eligible for inclusion if they had radiologically confirmed ACPO. Data were collected following review of patient notes into Microsoft Excel. Descriptive analysis was performed with no formal statistical assessment.

RESULTS

A total of 45 patients were identified, of whom 13 were admitted under general surgery. All patients received admission bloods (n=45). Nearly all patients had computed tomography imaging (43/45, 96%). Only 3/45 (6.7%) of the patients received optimal conservative management (intravenous infusion, nil by mouth, flatus tube, treatment of reversible causes). In all, 11/45 (24%) required further treatment, of whom 7 received this within 72 h. The leading (11/45) complication following diagnosis of ACPO was hospital-acquired pneumonia. Mortality was seen in 9/45.

CONCLUSIONS

ACPO is often managed remotely by general surgeons. This may impact on the quality of conservative management, and timeliness of endoscopic or pharmacological intervention. Further work is needed to optimise management.

Dolichocolon (redundant colon) in a rhesus macaque (Macaca mulatta)

Dolichocolon (redundant colon) is an underdiagnosed cause of severe constipation in humans. The clinical presentation reported here in a rhesus macaque closely resembles that of intestinal adenocarcinoma, the most common neoplasia in macaques. Dolichocolon should be considered in differential diagnosis of macaques with anorexia, weight loss, and constipation.

Outcomes for sigmoid volvulus managed with and without early definitive surgery: 20-year experience in a tertiary referral centre

BACKGROUND

Sigmoid volvulus is rare in Western countries. Patients at risk of sigmoid volvulus are often older with significant co-morbidity. Without sigmoid colectomy there is a high recurrence rate, but indications for surgery are controversial.

METHODS

A retrospective observational study was conducted by reviewing clinical records of patients admitted to Waikato Hospital 1 January 2000 to 1 January 2020 with a diagnosis of sigmoid volvulus. Patient characteristics, clinical features, investigations, management, and outcomes were recorded.

RESULTS

One hundred and thirty-two patients (87 male) were included with 203 volvulus episodes. Median age 76 years, median Charlson co-morbidity index (CCI) 4. Median follow-up 11 years. 44/132 (33.3%) had surgery during the index admission, two had elective surgery and the remainder had planned non-operative management. 73/132 (55.3%) had surgery at any stage. 42/86 (48.8%) patients managed non-operatively recurred; 66.7% of recurrences were within 6 months. Forty-three (32.6%) died within 12 months of index admission; 28 (21.2%) died during an admission for volvulus. On univariate analysis higher age and abnormal vital signs were associated with inpatient and 12-month mortality; higher CCI was associated with 12-month mortality. On multi-variate analysis increasing age in years was associated with increased risk of death (HR 1.089 [1.052-1.128, P < 0.001]). Normal vital signs at presentation were associated with decreased risk of death (HR 0.147 [0.065-0.334, P < 0.001]).

CONCLUSION

Sigmoid colectomy should be considered at index presentation with sigmoid volvulus. Half of patients managed non-operatively recurred, with two-thirds recurring within 6 months. The mortality rate remains high for subsequent volvulus episodes.

Development and validation of multivariable predictive models for recurrence and mortality following nonoperative management of sigmoid volvulus

AIM

Sigmoid volvulus is a challenging condition, and deciding between elective surgery or expectant management can be complex. The aim of this study was to develop a tool for predicting the risk of recurrent sigmoid volvulus and all-cause mortality within 1 year following initial nonoperative management.

METHOD

This is a retrospective cohort study using Medicare claims data from 2016 to 2018 of beneficiaries admitted urgently/emergently for volvulus, undergoing colonic decompression and discharged alive without surgery (excluding those discharged to hospice). The primary outcomes were recurrent sigmoid volvulus and all-cause mortality within 1 year. Proportional hazards models and logistic regression were employed to identify risk factors and develop prediction equations, which were subsequently validated.

RESULTS

Among the 2078 patients managed nonoperatively, 36.1% experienced recurrent sigmoid volvulus and 28.6% died within 1 year. The prediction model for recurrence integrated age, sex, race, palliative care consultations and four comorbidities, achieving area under the curve values of 0.63 in both the training and testing samples. The model for mortality incorporated age, palliative care consultations and nine comorbidities, with area under the curve values of 0.76 in the training and 0.70 in the testing sample.

CONCLUSION

This study provides a straightforward predictive tool that utilizes easily accessible data to estimate individualized risks of recurrent sigmoid volvulus and all-cause mortality for older adults initially managed nonoperatively. The tool can assist clinicians and patients in making informed decisions about such risks. While the accuracy of the calculator was validated, further confirmation through external validation and prospective studies would enhance its clinical utility.

Epidemiology and age-related trends in surgical outcomes for sigmoid volvulus: a 17-year analysis

BACKGROUND

Sigmoid volvulus, a gastrointestinal disorder characterized by twisted bowel, often requires medical intervention, either through endoscopic or surgical means, to avoid potentially severe outcomes. This study examined the challenges elderly patients face in undergoing surgical treatment, encompassing both mortality and morbidity. Furthermore, it aimed to determine how medical practices and outcomes have changed over a period of 17 years.

METHODS

We utilized data from the National Surgical Quality Improvement Project, which covers the period from 2005 to 2021, to identify patients who underwent left hemicolectomy for colonic volvulus. The patients were categorized into three age groups: < 60 years, 60-75 years, and > 75 years. We performed a meticulous logistic regression analysis, carefully adjusted for risk factors, to compare mortality, morbidity, and types of surgical treatment administered among the different age groups.

RESULTS

Our study included 6775 patients. The breakdown of the patient population was as follows: 2067 patients were < 60 years of age, 2239 were between 60 and 75 years of age, and 2469 were > 75 years of age. The elderly cohort, those aged above 75 years, were predominantly male, had lower BMIs, underwent fewer laparoscopic surgeries, required more diverting stomas and end-ostomies, and had longer hospital stays. Notably, the elderly population faced a mortality risk that was 5.67 times (95% CI 3.64, 9.20) greater than that of their youngest counterparts, with this risk increasing by 10% (95% CI 1.06, 1.14) for each additional year of age. Furthermore, the odds of mortality associated with emergency surgery were 1.63 times (95% CI 1.21, 2.22) higher than those associated with elective surgery. The postoperative morbidity odds were also elevated for emergency surgeries, 1.30 times (95% CI 1.08, 1.58) greater than that for elective cases. Over the 17-year period, we observed a decline in mortality rates, an increase in the utilization of laparoscopic procedures, and overall stability of morbidity rates.

CONCLUSION

Our findings highlight the increased vulnerability of patients over 75 years of age, who are not only at an elevated risk of mortality compared to their younger counterparts, but also a continuously increasing risk with age. By focusing on elective surgeries for younger patients and minimizing emergency surgeries for the elderly, it may be possible to reduce the mortality risk associated with surgical interventions in this population.

Seeds of Discomfort: An Unusual Case of Pediatric Abdominal Pain

This case describes a seven-year-old healthy boy who presented with seven days of abdominal pain, small-volume liquid stools, tenesmus, fevers, and dehydration after consuming an unknown amount of shelled watermelon seeds. He was ultimately found to have a large rectal seed bezoar that caused irritation, resulting in stercoral colitis with rectal inflammation. He was additionally found to have sigmoid volvulus during one of his disimpactions, which was also likely secondary to his rectal seed bezoar. This case uniquely highlights the importance of maintaining an index of suspicion for rectal seed bezoars, discusses previously unreported pediatric complications of rectal seed bezoars, including stercoral colitis and sigmoid volvulus, and addresses the management of this rare presentation.

Management of Colonic Emergencies

The etiology of colonic emergencies includes a wide-ranging and diverse set of pathologic conditions. Fortunately, for the surgeon treating a patient with one of these emergencies, the surgical management of these various causes is limited to choosing among proximal diversion, segmental colectomy with or without proximal diversion, or a total abdominal colectomy with end ileostomy (or rarely, an ileorectal anastomosis). The nuanced complexity in these situations usually revolves around the nonsurgical and/or endoscopic options and deciding when to proceed to the operating room.

Cecal volvulus with acute appendicitis in a 33-year-old male managed by manual detorsion, cecopexy, and appendectomy: A case report

INTRODUCTION

A volvulus is a serious surgical emergency caused by torsion or hyper-flexion of the bowel loop and its mesentery on a fixed point. Cecal volvulus is an uncommon cause of intestinal obstruction, accounting for just 1-1.5 % of all cases of bowel obstruction.

CASE PRESENTATION

A 33-year-old intellectually disabled male presented to the emergency department with complaints of generalized abdominal pain, absolute constipation, and non-projectile vomiting. He had a grossly distended and rigid abdomen with generalized tenderness and guarding. The abdomen was hyper-resonant. Bowel sounds were hypoactive. Digital rectal examination revealed an empty and collapsed rectum with no stool staining of the finger. Laboratory reports showed leukocytosis and neutrophilia. Radiographic imaging was consistent with acute intestinal obstruction. Laparotomy was performed, and cecal volvulus with viable bowel and acute appendicitis was diagnosed intra-operatively. Manual detorsion, cecopexy, and appendectomy were performed. The patient had an uneventful postoperative course. The patient is still on follow-up since June 2023, and no complication has occurred.

CLINICAL DISCUSSION

Cecal volvulus is an uncommon cause of intestinal obstruction with multiple etiologies. The annual incidence of cecal volvulus is estimated to be between 2.8 and 7.1 cases per million. Cecal volvulus may lead to life-threatening complications such as bowel ischemia and perforation.

CONCLUSION

Diagnosis of cecal volvulus must be made promptly to prevent bowel gangrene and perforation. In this case, manual detorsion and cecopexy were performed as the bowel was viable per-operatively due to early surgical intervention.

Reversed midgut rotation revealed by cecal volvulus in the elderly: A case report

INTRODUCTION

Reverse midgut rotation constituted an extremely rare intestinal malrotation. Its recognition in the elderly was challenging as in our case revealed by cecal volvulus.

CASE PRESENTATION

A 78-years old man consulted for diffuse abdominal, vomiting, bowel movement and passing gas inability. Computed tomography concluded to cecal and last ileum loop volvulus with small intestine dilation upstream. Emergent laparotomy confirmed the existence of a cecal volvulus associated to a reversed midgut rotation non diagnosed at computed tomography before surgery. A Ladd' procedure was carried out. An isoperistaltic side-by-side ileocolic manual anastomosis was performed.

DISCUSSION

Our case illustrated an extremely rare reversed midgut rotation in the elderly accounting for 2 to 7 % of all embryologic midgut malrotation anomalies. It could be revealed by mobile right colon volvulus as in our case, whole midgut volvulus, retro-arterial tunnel pressure transverse colon stenosis, or Ladd' bands duodenojejunal obstruction. Its recognition at the elderly was challenging and needed careful computed tomography combined signs determination. Surgical treatment accounted for the treatment of choice for reversed midgut rotation especially in emergency settings as in our case. Ladd' procedure is still the most performed procedure.

CONCLUSIONS

Reverse midgut rotation constituted an extremely rare congenital intestinal malrotation. Its diagnosis in the elderly was challenging implicating careful interpretation of computed tomography.

Percutaneous endoscopic cecostomy for management of Ogilvie's syndrome: a case series and literature review with an update on current guidelines (with video)

INTRODUCTION

Percutaneous endoscopic cecostomy (PEC) is a viable treatment option for patients with persistent or recurrent acute colonic pseudo-obstruction (ACPO; Ogilvie's syndrome). It should be generally considered in patients that are refractory to pharmacologic and endoscopic decompression, especially those not amenable to surgical intervention due to an increased perioperative risk. Physicians are rather unfamiliar with this approach given the limited number of reports in the literature and paucity of guideline resources, although guidelines concerning ACPO and covering the role of endoscopy were recently published by three major expert societies, all within the last 2 years.

PATIENTS AND METHODS

We retrospectively identified three consecutive patients who underwent PEC placement at a Czech tertiary referral center between May 2018 and December 2021: all for recurrent ACPO. In addition, we summarized the current guidelines in order to present the latest knowledge related both to the procedure and management approach in patients with ACPO.

RESULTS

The placement of PEC was successful and resulted in clinical improvement in all cases without any adverse events.

CONCLUSION

The results of our experience are in line with previous reports and suggest that PEC may become a very useful tool in the armamentarium of modalities utilized to treat ACPO. Furthermore, the availability of guideline resources now offers comprehensive guidance for informed decision-making and the procedural aspects.

A Percutaneous Endoscopic Colostomy Tube to the Rescue

Percutaneous endoscopic colostomy (PEC) tube placement is a minimally invasive procedure used to treat recurrent colonic pseudo-obstruction, sigmoid volvulus, chronic intractable constipation, and neurogenic bowel. PEC is a viable treatment alternative for patients who have failed conservative therapies and are deemed high risk for surgical management. We present a case of acute colonic pseudo-obstruction after Clostridioides difficile infection that was unresponsive to medical treatment or endoscopic decompression. A PEC tube was placed into the transverse colon with successful resolution of the colonic distension.

Pyridostigmine in chronic intestinal pseudo-obstruction - a systematic review

BACKGROUND

Chronic intestinal pseudo-obstruction (CIPO) may be a primary or secondary phenomenon and is often multifactorial. Treatment is largely directed at improving colonic motility. The use of cholinesterase inhibitors such as pyridostigmine has been hypothesized to increase acetylcholine in the bowel, improving symptoms and transit times.

METHODS

A systematic review of the use of pyridostigmine in CIPO was conducted using scientific and commercial search engines identifying scientific studies enrolling adult human subjects, published from 2000 to 2022 in the English language.

RESULTS

Four studies were identified including two randomized controlled trials (RCT) and two observational studies. The studies had heterogenous inclusion criteria, dosing regimens and reported outcomes. Two studies were identified as being at high risk of bias. All studies reported improved patient outcomes with use of pyridostigmine, and low rates (4.3%) of mild cholinergic side effects. No major side effects were reported.

CONCLUSION

The use of pyridostigmine in management of CIPO is biologically plausible due to its ability to increase colonic motility, and early studies on its role are uniformly suggestive of benefit with low side-effect profile. Four clinical studies have been conducted to date, with small sample sizes, heterogeneity and high risk of bias. Further high-quality studies are required to enable assessment of pyridostigmine's utility as an effective management strategy in CIPO.

Update on the Diagnosis and Management of Acute Colonic Pseudo-obstruction (ACPO)

PURPOSE OF REVIEW

Acute Colonic Pseudo-obstruction (ACPO) is a cause of large intestinal dilation and obstruction without any physical transition point. It remains difficult to diagnose and treat. We review the recent updates on diagnosis and management of ACPO.

RECENT FINDINGS

Recent guidelines have posited that conservative management can be tried in most cases of ACPO, but that early decompression and surgery should be considered. Use of neostigmine is still a viable option but there is also promising data on pyridostigmine as well as prucalopride. Resolution of ACPO should be followed by daily use of polyethylene glycol (PEG) to help prevent recurrence. ACPO warrants early and accurate diagnosis with exclusion of alternate causes of large bowel dilation. Conservative management can be attempted for 48-72 h in those with cecal diameters < 12 cm and without signs of peritonitis and perforation. Early escalation of management should be attempted with neostigmine followed by endoscopy and/or surgery as needed, given that longer periods of dilation are associated with worse outcomes. There is promising new evidence for use of pyridostigmine and prucalopride, but further trials are needed prior to incorporating them into regular use. Finally, studies are lacking regarding prevention of ACPO after initial resolution.

Twists and turns: A case report of cecal volvulus

We present a case of a 22-year-old male presenting in the emergency room with colicky abdominal pain, vomiting, and abdominal distension for which an early computed tomography scan was done and diagnosed as cecal volvulus. Following diagnosis case was managed promptly by laparotomy with right hemicolectomy and primary anastomosis.

Cecal Volvulus: A Report of a Challenging Case

Cecal volvulus represents a rare form of acute intestinal obstruction caused by an axial twist of the terminal ileum, ascending colon, and cecum surrounding the mesenteric pedicle. It is responsible for 1%-1.5% of all intestinal obstruction cases in adults. Radiological imaging assists in the diagnosis of cecal volvulus, particularly a CT scan with contrast as the gold standard for both diagnosis and risk assessment. In this case report, we present a challenging case of cecal volvulus seen in a 75‑year‑old male patient with multiple comorbidities who presented with abdominal guarding/tenderness and high WBC and lactate, which evolved into septic shock. The purpose of this study is to underline the significance of early diagnosis and effective treatment of this uncommon condition in abdominal surgeries.

Caecal Volvulus Presenting as an Obstructed Inguinal Hernia: A Case Report

Caecal volvulus (CV) is an uncommon cause of large intestinal obstruction due to the axial torsion of the caecum, ascending colon, and terminal ileum. We describe the case of a 37-year-old man who presented with bilateral inguinal hernias (the left larger than the right), diffuse abdominal pain, vomiting, difficulty passing stool, and flatus that were comparable to those of an obstructed hernia. Imaging tests revealed a collapsed ascending colon, free fluid collection, and a significantly dilated proximal ileum. An urgent laparotomy showed a perforated, clockwise-twisted caecum that required a right hemicolectomy. Postoperatively, the patient had a good recovery. CV is uncommon, and its symptoms are vague, making diagnosis difficult. For an accurate diagnosis and prompt action, imaging tools and a high index of suspicion are essential. This case serves as a reminder of the significance of taking rare entities into consideration in developing a differential diagnosis of complex abdominal presentations and the necessity for a differential diagnostic approach to choose the most suitable surgical course of action.

Ogilvie Syndrome, Bradycardia, and Neostigmine

Acute colonic pseudo-obstruction (ACPO), known as Ogilvie Syndrome, is an acute dilation of the colon in the absence of an underlying mechanical or anatomic cause. Neostigmine treatment is indicated following failed conservative management of ACPO, however neostigmine has its contraindications. This is a report of a unique case of a patient with a past medical history of symptomatic first degree heart block with a permanent pacemaker who received a bolus dosage of neostigmine treatment for ACPO in an ICU setting.

A Challenge Called Ogilvie´s Syndrome

Ogilvie´s syndrome is a colonic dilation without any existing mechanical obstruction. The risk factors that cause it are not completely understood, but if untreated, the distension can result in rupture or ischaemic bowel perforation. Additionally, the existing guidelines do not agree with each other about the next steps if conservative treatment fails. We report the case of a 71-year-old woman in whom Ogilvie´s syndrome was particularly difficult to manage, and with it, we try to add clinical data to a field with scarce evidence.

Bowel Preparation Before Nonelective Sigmoidectomy for Sigmoid Volvulus: Highly Beneficial but Vastly Underused

BACKGROUND

Although strong evidence exists for combined mechanical and oral antibiotic bowel preparation before elective colorectal resection, the utility of preoperative bowel preparation for patients undergoing sigmoid resection after endoscopic decompression of sigmoid volvulus has not been previously examined. The goal of this study was to evaluate the association between bowel preparation and postoperative outcomes for patients undergoing semielective, same-admission sigmoid resection for acute volvulus.

STUDY DESIGN

Patients from the 2012 to 2019 Colectomy-Targeted American College of Surgeons NSQIP dataset who underwent sigmoid resection with primary anastomosis after admission for sigmoid volvulus were included. Multivariable logistic regression was used to compare the risk-adjusted 30-day postoperative outcomes of patients who received combined preoperative bowel preparation with those of patients who received either partial (mechanical or oral antibiotic alone) or incomplete bowel preparation. Effort was made to exclude patients whose urgency of clinical condition at hospital admission precluded an attempt at preoperative decompression and subsequent bowel preparation.

RESULTS

Included were 2,429 patients, 322 (13.3%) of whom underwent complete bowel preparation and 2,107 (86.7%) of whom underwent partial or incomplete bowel preparation. Complete bowel preparation was protective against several postoperative complications (including anastomotic leak), mortality, and prolonged postoperative hospitalization.

CONCLUSIONS

This study demonstrates a significant benefit for complete bowel preparation before semielective, same-admission sigmoid resection in patients with acute sigmoid volvulus. However, only a small percentage of patients in this national sample underwent complete preoperative bowel preparation. Broader adoption of bowel preparation may reduce overall rates of complication in patients who require sigmoid colectomy due to volvulus.

Stage IV Colorectal Cancer Management and Treatment

(1) Background: Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related mortality worldwide. Up to 50% of patients with CRC develop metastatic CRC (mCRC). Surgical and systemic therapy advances can now offer significant survival advantages. Understanding the evolving treatment options is essential for decreasing mCRC mortality. We aim to summarize current evidence and guidelines regarding the management of mCRC to provide utility when making a treatment plan for the heterogenous spectrum of mCRC. (2) Methods: A comprehensive literature search of PubMed and current guidelines written by major cancer and surgical societies were reviewed. The references of the included studies were screened to identify additional studies that were incorporated as appropriate. (3) Results: The standard of care for mCRC primarily consists of surgical resection and systemic therapy. Complete resection of liver, lung, and peritoneal metastases is associated with better disease control and survival. Systemic therapy now includes chemotherapy, targeted therapy, and immunotherapy options that can be tailored by molecular profiling. Differences between colon and rectal metastasis management exist between major guidelines. (4) Conclusions: With the advances in surgical and systemic therapy, as well as a better understanding of tumor biology and the importance of molecular profiling, more patients can anticipate prolonged survival. We provide a summary of available evidence for the management of mCRC, highlighting the similarities and presenting the difference in available literature. Ultimately, a multidisciplinary evaluation of patients with mCRC is crucial to selecting the appropriate pathway.

Constipation in transverse myelitis

Transverse myelitis is an extremely rare neuroinflammatory disorder. About half of the affected patients develop paraplegia associated with urinary and bowel dysfunction. The bowel dysfunction is thought to be benign and is usually managed with dietary management and laxatives. We report a case of a man in his 60s presenting with transverse myelitis and the acute disease course complicated with treatment refractory intestinal dysfunction resulting in intestinal perforation, eventually leading to his death. Thus, this case helps us weigh the fact that intestinal dysfunction in the case of transverse myelitis is not always benign but can lead to deadly outcomes as well.

Value of Humanized Nursing under Emergency Green Channel on Gastrointestinal Function Recovery in Patients with Acute Intestinal Obstruction after Operation

Acute intestinal obstruction (AIO) is one of the most common surgical acute abdomens. Emergency green channel refers to a fast and efficient service system provided by hospitals for critically ill patients. It is the key to ensure that emergency patients receive timely, standardized, efficient and thoughtful medical services, improve the success rate of rescue, and reduce medical risks. Acute intestinal obstruction is mainly treated by surgery in the clinic. Previous reports have shown that the application of different nursing methods in the operation of acute intestinal obstruction has different effects on the results of surgical treatment. In this study, the clinical data of 80 patients with AIO were retrospectively analyzed to explore the value of humanistic care under the emergency green channel in promoting the recovery of gastrointestinal function after AIO surgery.

Sigmoid volvulus: Evaluating identification strategies and contemporary multicenter outcomes

BACKGROUND

There is limited epidemiologic data on sigmoid volvulus (SV) from non-endemic regions. Therefore, we performed a multicenter study to report contemporary outcomes and appraise literature-based methods that pair diagnostic and procedural codes to identify SV.

METHOD

Using an automated search for patients with 'volvulus' in our system from 2011 to 2021, we reviewed electronic charts to clarify the diagnosis, automatically replicate three strategies to identify SV, and retrieved 6-month outcomes.

RESULTS

Of 895 patients, 109 had SV. Literature-based strategies poorly identified SV. At the index admission, patients underwent endoscopic reduction alone (33%), emergent (16.5%), semi-elective (34%), or elective (16.5%) surgery. Endoscopic reduction alone had high recurrence rates and delayed surgery was associated with worse outcomes.

CONCLUSION

Literature-based strategies to identify SV suffer from misclassification bias which affects patient counseling. In this large series, one-third of patients do not undergo during their index admission despite improved outcomes with earlier surgery.

Acute Colonic Pseudo-Obstruction

CASE SUMMARY

A 33-year-old man with a history of chronic alcohol use, generalized anxiety disorder, and hypertension presented to the emergency department after a syncopal event. He was admitted to the medical intensive care unit for alcohol withdrawal, requiring intubation and sedation. On hospital day 7, abdominal x-ray image demonstrated a dilated cecum to 12 cm, transverse colon dilation to 7 cm, and decompressed distal colon ( Fig. 1 ). CT scan of the abdomen and pelvis confirmed dilation of the cecum and ascending and transverse colons ( Fig. 2 ). Colonoscopy showed no evidence of distal obstruction, but colonic distension persisted, and he subsequently underwent cecal decompression with an open "blow-hole" cecostomy fully matured at skin level via a small right lower quadrant incision. The nasogastric tube was removed on postoperative day 2, and his diet was slowly advanced. Abdominal x-ray image on postoperative day 5 demonstrated no colonic dilation. He was discharged home on postoperative day 7. The patient re-presented to the hospital 3 months later with cecostomy prolapse. He underwent cecostomy takedown with ileocecectomy via circumstomal incision. He was discharged home on postoperative day 2.

Is Laparoscopy Underutilized for Sigmoid Volvulus?

PURPOSE

Minimally invasive surgery has become increasingly prevalent. However, the majority of colectomies for volvulus are still performed via an open technique. The purpose of this study is to determine whether there is a difference in outcomes between laparoscopic and open procedures for sigmoid volvulus.

MATERIALS AND METHODS

The American College of Surgeons National Surgical Quality Improvement Program and colectomy-targeted procedure databases were queried from 2013 to 2018. Patients undergoing partial colectomy without ileal resection for the indication of volvulus were compared based on approach (planned laparoscopic vs. planned open). The 2 groups were propensity score matched for perioperative variables. A subgroup analysis was performed comparing unplanned laparoscopic conversion to open (CTO) with planned open procedures. The primary outcomes were overall morbidity, mortality, and length of stay.

RESULTS

Total 2493 patients were identified. Four hundred ninety-two cases began laparoscopically (20%), of which 391 were completed laparoscopically (79%). Laparoscopic approach was associated with longer operative times (133 vs. 104 min, P<0.001). Laparoscopic approach was associated with decreased overall morbidity (OR: 0.71, 95% CI, 0.54 to 0.93) and decreased length of stay when >7 days (OR: 0.70, 95% CI, 0.52 to 0.94). On subgroup analysis, there was no difference in outcomes when comparing unplanned CTO to planned open approach.

CONCLUSIONS

Laparoscopic approach is used in a fraction of cases for colonic volvulus. When utilized, the majority are completed without CTO. Laparoscopy is associated with fewer complications and shorter hospital stays. Even with unplanned conversion to open, there is no difference in outcomes compared against planned open procedures. Surgeons should consider the utilization of laparoscopy for colonic volvulus.

Back Propagation Neural Network-Based Magnetic Resonance Imaging Image Features in Treating Intestinal Obstruction in Digestive Tract Diseases with Chengqi Decoction

This study was to explore the adoption effect of magnetic resonance imaging (MRI) image features based on back propagation neural network (BPNN) in evaluating the curative effect of Chengqi Decoction (CD) for intestinal obstruction (ileus), so as to evaluate the clinical adoption value of this algorithm. Ninety patients with ileus were recruited, and the patients were treated with CD and underwent MRI scans of the lower abdomen. A BPNN model was fabricated and applied to segment the MRI images of patients and identify the lesion. As a result, when the overlap step was 16 and the block size was 32 × 32, the running time of the BPNN algorithm was the shortest. The segmentation accuracy was the highest if there were two hidden layer (HL) nodes, reaching 97.3%. The recognition rates of small intestinal stromal tumor (SIST), colon cancer, adhesive ileus, and volvulus of MRI images segmented by the algorithm were 91.5%, 88.33%, 90.3%, and 88.9%, respectively, which were greatly superior to those of manual interpretation (P < 0.05). After the intervention of CD, the percentages of patients with ileus that were cured, markedly effective, effective, and ineffective were 65.38%, 23.16%, 5.38%, and 6.08%, respectively. The cure rate after intervention of CD (65.38%) was much higher in contrast to that before intervention (13.25%) (P < 0.05). In short, CD showed a good therapeutic effect on ileus and can effectively improve the prognosis of patients. In addition, MRI images based on BPNN showed a good diagnostic effect on ileus, and it was worth applying to clinical diagnosis.

The Unfolding Situation of Caecal Volvulus: A Retrospective Analysis of 36 Cases From a Single Center

Background

Caecal volvulus (CV) is a rare cause of bowel obstruction. However, there has been a steady rise in the number of cases over the decades. The demographic profile of patients developing CV has changed to a much older population. We conducted a retrospective review to determine the incidence, demographic profile, management, and outcomes of CV patients in our institution during the last nine years.

Methodology

A retrospective audit of all patients diagnosed with CV at Worcestershire Acute Hospitals NHS Trust between 01 January 2011 and 31 March 2020 was performed. Patients admitted with any other type of volvuli such as sigmoid volvulus, small bowel volvulus, and gastric volvulus were excluded.

A systematic search of the electronic medical records for all patients admitted under the International Classification of Diseases, Tenth Revision code K562: volvulus was performed for the study duration. It yielded a total of 1,019 patients. After excluding all patients who did not have either a CV or caecal bascule, we included 36 patients in the final analysis.

Results

Most of our patients were females (78%) with a median age was 76 years. The majority (86%) had at least one medical comorbidity, and 36% had a previous abdominal operation. Abdominal pain was the main complaint in 94% of patients. All patients had undergone a computed tomography (CT) scan to confirm their diagnosis. Most of our patients (84%) underwent surgery. Open right hemicolectomy was the most commonly performed operation (87%). Out of the six patients who did not undergo surgery, three responded to bowel rest and nasogastric tube decompression; one patient underwent successful colonoscopic decompression. In contrast, two patients, unfortunately, passed away. The median length of hospital stay was nine days, with a 30-day mortality of 3%.

Conclusions

CV remains a rare cause of bowel obstruction. Most of our patients were old, frail, and had medical comorbidities. More than one-third of patients had undergone previous abdominal surgery. Early CT scan followed by right hemicolectomy was associated with low mortality.

Sigmoid volvulus: Treatment options and volvulus recurrence

Sigmoid Volvulus (SV) is principally treated with non-operative decompression, whereas it may require surgical management in some situations. Depending upon the treatment method, SV recurs in about one fourth of the cases, which doubles the mortality and morbidity rates. In this paper, we discuss the management and related recurrence of SV in the light of the largest single-center SV series over the world.
