Outcomes of first-line endoscopic management for patients with sigmoid volvulus

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.

Clinical outcome of patients treated with endoscopic decompression after failure of detorsion for uncomplicated sigmoid volvulus

Background

Endoscopic treatment is the first-line therapy for uncomplicated sigmoid volvulus (SV). However, there are few reports on the clinical course of SV. We investigated the clinical courses of successful and unsuccessful endoscopic detorsions for bowel decompression in patients with uncomplicated SV.

Methods

Between May 2009 and February 2022, patients with uncomplicated SV who underwent endoscopic detorsion or decompression only if detorsion failed were enrolled. A case analysis (all cases) and a patient analysis (first episode cases) were performed. Outcomes were compared between the detorsion and decompression groups, including length of hospital stay, recurrence rate, and days to readmission due to SV.

Results

Seventy patients were included in this study. The success rate of endoscopic detorsion of the SV was 28.6%. There were no differences in age, sex, or other characteristics between the two groups. The hospital stay tended to be longer in the decompression group than in the detorsion group. However, there was no difference in the 30-day, 6-month, or 12-month recurrence rate or the number of days to readmission for SV between the two groups in the case and patient analyses.

Conclusions

This study suggests that endoscopic decompression is a feasible alternative to endoscopic detorsion in patients with uncomplicated SV.

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.

Endoscopic sigmoidopexy for recurrent sigmoid volvulus in inoperable patients: a retrospective series of 15 patients

BACKGROUND

Recurrent sigmoid volvulus is frequent and sometimes occurs in frail patients with contraindications to surgical sigmoidectomy. Percutaneous endoscopic sigmoidopexy (PES) has recently been proposed as an alternative to elective sigmoidectomy. We aimed to describe the efficacy and safety of PES.

METHODS

All consecutive patients who underwent PES for recurrent sigmoid volvulus at two French centers between January 2017 and March 2021 were included in this retrospective case series. Recurrent sigmoid volvulus was defined as at least two symptomatic episodes treated by endoscopic decompression. Under endoscopic guidance, anchors were placed to attach the sigmoid to the anterior abdominal wall, allowing the placement of pigtail Chait catheters.

RESULTS

15 patients (60 % female; median age 74 years [range 49-96]) were included. Median number of previous sigmoid volvulus episodes was 3 (range 2-6). Procedures were technically successful with no intraprocedural adverse events for 14 patients (93 %). Peritonitis occurred at Day 2 in one patient (serious adverse event rate 7 %). Median follow-up time was 10 months (range 1-30). No sigmoid volvulus recurrence occurred during follow-up.

CONCLUSION

PES using Chait catheters was feasible and effective for recurrent sigmoid volvulus and should be considered as an alternative to sigmoidectomy in inoperable patients.

Total colonic volvulus with a 720° twist of freely mobile colon

Segmental colonic volvulus involving the sigmoid or ileocaecal region is an important cause of large bowel obstruction and a well-established surgical emergency. Volvulus of the entire colon however is hazardously rare, in which case the diagnosis is likely to be made intraoperatively. The surgeon is then faced with the conundrum of the best surgical management, especially in the case of early intervention with viable bowel. To our knowledge this has never been reported.

Laparoscopic fixation of volvulus by extra-peritonealization: a case series

BACKGROUND

Volvulus is one of the leading causes of colonic obstruction with a high recurrence rate following endoscopic decompression. Although colonic resection remains the treatment of choice, it is often associated with significant morbidity and mortality, especially in elderly patients. Colonic fixation with extra-peritonealization has been suggested as an alternative to colonic resection. The aim of this study was to evaluate the surgical outcomes of patients with colonic volvulus in our initial experience with this procedure.

METHODS

A retrospective analysis of a prospectively maintained database of all patients who underwent colonic extra-peritonealization for volvulus between January 2016 and April 2021 in Sheba medical center (Ramat-Gan, Israel) was performed. Patients' demographics, clinical, peri-operative and post-operative data were recorded and analyzed.

RESULTS

One hundred and thirty nine patients were admitted due to acute colonic volvulus, 48 of whom were treated surgically. Eleven patients underwent extra-peritonealization of the sigmiod or cecum during the study period. Mean age was 64.5 years. Six patients (54.55%) were males. Seven patients (63.63%) presented with sigmoid volvulus and 4 (36.36%) with cecal volvulus. Median American Society of Anesthesiologists (ASA) class was 3 (range 2-4). One patient (9.09%) was required urgent surgery. The majority of patients was operated on using a laparoscopic approach (10 patients, 90.9%). Median length of stay was 3 days (range 1-6 days) and no post-operative complications or readmissions within 30 days after surgery were recorded. Median length of follow-up was 283 days (range 21-777 days). During the follow-up period, three patients (27.27%) presented with recurrent volvulus and required an additional surgical intervention with colonic resection. Of the patients with volvulus recurrence, one patient (9.09%) required an urgent surgical intervention.

CONCLUSIONS

Extra-peritonealization of colonic volvulus is feasible and safe. Although recurrence rates are fairly high, the low morbidity associated with the procedure makes it an appealing alternative to colonic resection, especially in patients with high risk for post-operative complications.

Prognostic factors in the decision-making process for sigmoid volvulus: results of a single-centre retrospective cohort study

Background

Sigmoid volvulus is a common cause of emergency surgical admission. Those patients are often treated conservatively with a high rate of recurrence. We wondered if a more aggressive management might be indicated.

Methods

We have reviewed data of patients diagnosed with acute sigmoid volvulus over a 2-year period. The primary endpoint was patient survival.

Results

We analysed 332 admissions of 78 patients. 39.7% underwent resection. Survival was 54.9 ± 8.8 months from the first hospitalization, irrespective of the treatment. Long-term survival was positively influenced by being female, having a low “social score”, a younger age and surgery. Multivariate analysis showed that only being female and surgery were independently associated with better survival.

Conclusion

Early surgery may be the best approach in patients with recurrent sigmoid volvulus, as it ensures longer survival with a better quality of life, regardless of the patient’s social and functional condition.

Sigmoid volvulus: outcomes of treatment and predictors of morbidity and mortality

Purpose

To analyze the treatment outcomes for sigmoid volvulus (SV) and identify risk factors of complications and mortality.

Methods

Observational study of all consecutive adult patients diagnosed with SV who were admitted from January 2000 to December 2020 in a tertiary university institution for conservative management, urgent or elective surgery. Primary outcomes were 30-day postoperative morbidity, mortality and 2-year overall survival (OS), including analysis of risk factors for postoperative morbidity or mortality and prognostic factors for 2-year OS.

Results

A total of 92 patients were included. Conservative management was performed in 43 cases (46.7%), 27 patients (29.4%) underwent emergent surgery and 22 (23.9%) were scheduled for elective surgery. Successful decompression was achieved in 87.8% of cases, but the recurrence rate was 47.2%. Mortality rates following episodes were higher for conservative treatment than for urgent or elective surgery (37.2%, 22.2%, 9.1%, respectively; p = 0.044). ASA score > III was an independent risk factor for complications (OR = 5.570, 95% CI = 1.740–17.829, p < 0.001) and mortality (OR = 6.139, 95% CI = 2.629–14.335, p < 0.001) in the 30 days after admission. Patients who underwent elective surgery showed higher 2-year OS than those with conservative treatment (p = 0.011). Elective surgery (HR = 2.604, 95% CI = 1.185–5.714, p = 0.017) and ASA score > III (HR = 0.351, 95% CI = 0.192–0.641, p = 0.001) were independent prognostic factors for 2-year OS.

Conclusion

Successful endoscopic decompression can be achieved in most SV patients, but with the drawbacks of high recurrence, morbidity and mortality rates. Concurrent severe comorbidities and conservative treatment were independent prognostic factors for morbidity and survival in SV.

Endoscopic Decompression of Sigmoid Volvulus: Review of 748 Patients

Background: Sigmoid volvulus (SV) is the twisting of the sigmoid colon around itself. Endoscopy both helps diagnosis and provides treatment in the absence of peritonitis or perforation in SV. Nevertheless, there are some controversies or limitations on this subject. The aim of this study is to evaluate the current role of the endoscopic decompression in the treatment of SV. Materials and Methods: The clinical records of 1040 patients with SV treated over a 55-year period from June 1966 to July 2021 were reviewed retrospectively until June 1986 and prospectively thereafter. For each case, preoperational parameters, treatment options, and prognosis were noted. Results: Endoscopic decompression was tried in 748 patients (71.9%). The procedure was successful in 585 cases (83.2%), whereas unsuccessful in 118 (16.8%) of 703 patients (94.0%) with viable bowel. The mortality rate was 0.5% (4 patients), the morbidity rate was 1.9% (14 patients), the early recurrence rate was 5.5% (32 patients), whereas the mean hospitalization period was 34.6 hours (range: 24-96 hours). Conclusions: Despite some controversies or limitations in some subjects including the strategy in ischemic or gangrenous cases, the factors affecting the success, kind of the used instruments, technical details of the application, role of the flatus tubes, and the specific topics such as SV in childhood or pregnancy, endoscopic decompression is the first-line therapy in selected patients with SV.

Surgical Management of Sigmoid Volvulus: A Multicenter Observational Study

Purpose: This study aimed to evaluate real-world clinical outcomes from surgically treated patients for sigmoid volvulus.Methods: Five tertiary centers participated in this retrospective study with data collected from October 2003 through September 2018, including demographic information, preoperative clinical data, and information on laparoscopic/open and elective/emergency procedures. Outcome measurements included operation time, postoperative hospitalization, and postoperative morbidity.Results: Among 74 patients, sigmoidectomy was the most common procedure (n = 46), followed by Hartmann’s procedure (n = 23), and subtotal colectomy (n = 5). Emergency surgery was performed in 35 cases (47.3%). Of the 35 emergency patients, 34 cases (97.1%) underwent open surgery, and a stoma was established for 26 patients (74.3%). Elective surgery was performed in 39 cases (52.7%), including 21 open procedures (53.8%), and 18 laparoscopic surgeries (46.2%). Median laparoscopic operation time was 180 minutes, while median open surgery time was 130 minutes (P < 0.001). Median postoperative hospitalization was 11 days for laparoscopy and 12 days for open surgery. There were 20 postoperative complications (27.0%), and all were resolved with conservative management. Emergency surgery cases had a higher complication rate than elective surgery cases (40.0% vs. 15.4%, P = 0.034).Conclusion: Relative to elective surgery, emergency surgery had a higher rate of postoperative complications, open surgery, and stoma formation. As such, elective laparoscopic surgery after successful sigmoidoscopic decompression may be the optimal clinical option.

Endoscopic Detorsion Results in Sigmoid Volvulus: Single-Center Experience

Endoscopic detorsion is the first-line recommended treatment modality in sigmoid volvulus patients who have no peritoneal irritation signs on admission. In this paper, we present the results of endoscopic detorsion procedures applied at the time of presentation with the diagnosis of sigmoid volvulus and review the current literature about this topic.

American Society for Gastrointestinal Endoscopy guideline on the role of endoscopy in the management of acute colonic pseudo-obstruction and colonic volvulus

Colonic volvulus and acute colonic pseudo-obstruction (ACPO) are 2 causes of benign large-bowel obstruction. Colonic volvulus occurs most commonly in the sigmoid colon as a result of bowel twisting along its mesenteric axis. In contrast, the exact pathophysiology of ACPO is poorly understood, with the prevailing hypothesis being altered regulation of colonic function by the autonomic nervous system resulting in colonic distention in the absence of mechanical blockage. Prompt diagnosis and intervention leads to improved outcomes for both diagnoses. Endoscopy may play a role in the evaluation and management of both entities. The purpose of this document from the American Society for Gastrointestinal Endoscopy's Standards of Practice Committee is to provide an update on the evaluation and endoscopic management of sigmoid volvulus and ACPO.
