Postoperative effects of laparoscopic Hartmann reversal: A multicenter propensity score matched study

BACKGROUND

Although the advantages of laparoscopic Hartmann reversal (LHR) compared to open Hartmann reversal (OHR) have been reported in the literature, the number of multicenter studies with good matching investigating this topic is rare. In the present study, we aimed to confirm the advantages of LHR in terms of short-term outcomes through propensity score matching of LHR and OHR groups, using data collected from multiple institutions.

METHODS

Patients who underwent Hartmann reversal at six institutions under the Catholic Medical Center of the Catholic University of Korea between January 1, 2005, and December 31, 2021, were included. The patients were divided into the LHR and OHR groups based on the technique used. The two groups were matched using propensity score matching (1:1 ratio, logistic regression with the nearest-neighbor method). The primary outcome was postoperative ileus (POI) frequency, and secondary outcomes were time to solid diet (days) and length of stay (days).

RESULTS

Among 337 patients, propensity score matching was performed on 322, after excluding 15 who had undergone open conversion. Of these, 63 patients were assigned to each group through propensity score matching. There was no difference in the frequency of adhesiolysis (77.8% vs. 82.5%, p = 0.503) or the operation time. (210 (IQR 159-290) vs. 233 (IQR 160-280), p = 0.718) between the two groups. As the primary outcome, the LHR group showed significantly lower POI frequency than the OHR group. (4.8% vs. 22.2%, p = 0.0041) Regarding the secondary outcomes, the LHR group showed a shorter period to solid diet than the OHR group. The length of hospital stay was also significantly shorter in the LHR group (4 vs. 6, p < 0.0001; 9 vs. 12, p<0.0001).

CONCLUSION

LHR is an effective method to ensure faster recovery of patients after surgery compared to OHR.

Factors Predicting the Reversal of Hartmann’s Procedure

Aim

This paper investigates the risk factors preventing the reversal and nonreversal of Hartmann's procedure, as a surgical technique that has been performed in our clinic for ten years.

Methods

The study involved a ten-year Hartmann's procedure followed up at our center. The patients were divided into Hartmann reversal and nonreversal groups. Groups were examined in terms of age, gender, diagnosis, stage of malignancy, ASA score, comorbidity, perioperative morbidity-mortality, and the length of the operation.

Results

Age (p < 0.001), ASA score (p < 0.001), stage in case of malignancy (p = 0.002), and comorbidities (p < 0.001) were significant risk factors. The ratio of patients without any comorbidities to those with one or more comorbidities was 2.63 (95% CI 1.12–6.20). Among the malignant patients, the ratio of early-stage patients to advanced-stage patients in the group with reversal of Hartmann's colostomy was 2.82 (95% CI 1.30–6.10). In addition, the ratio of older patients to younger patients in group 2 was 0.95 (95% CI 0.92–0.98). A univariate analysis revealed that younger patients, those with lower ASA scores, those without comorbidities, and those with early-stage malignancy had a greater chance of closure of the stoma.

Conclusion

Although Hartmann's procedure is performed in emergency surgery, the nonreversal of the colostomy is a problem in itself. It should be kept in mind that patients who have high risks are likely to have a permanent stoma.

Is laparoscopy a reliable alternative to laparotomy in Hartmann's reversal? An updated meta-analysis

BACKGROUND

The aim of this study was to perform a systematic review of the literature on and updated meta-analysis of surgical postoperative complications after laparoscopic Hartmann's reversal (LHR) and open Hartmann's reversal (OHR).

METHODS

Studies comparing LHR versus OHR published from inception until June 2020 were selected and submitted to a systematic review and meta-analysis. Articles were searched in the MEDLINE and Cochrane Trials Register databases. Meta-analysis was performed with Review Manager 5.0.

RESULTS

Twenty-three retrospective comparative studies (including 5 case-controlled studies) with a total of 3139 patients with LHR and a total of 10,325 patients with OHR were included. Meta-analysis showed that LHR was significantly associated with a decreased rate of revision surgery (OR = 0.73, 95% CI = 0.60-0.89, p < 0.001), anastomotic leakage (OR = 0.61, 95% CI = 0.49-0.75, p < 0.00001), postoperative morbidity (OR = 0.53, 95% CI = 0.47-0.58, p < 0.00001), intra-abdominal abscess (OR = 0.67 [0.52-0.87], 95% CI = , p = 0.003), wound abscess (OR = 0.53 [0.46-0.61], 95% CI = , p < 0.00001), and postoperative ileus (OR = 0.46, 95% CI = 0.29-0.72, p = 0.0008), respectively. Conversely, mortality was comparable between LHR and OHR.

CONCLUSIONS

These results suggest that LHR significantly improved surgical postoperative outcomes. However, considering the low level of evidence, further randomized trials are required to validate these findings.

Analysis of factors affecting reversal of Hartmann's procedure and post-reversal complications

Although Hartmann’s procedure (HP) is commonly used as emergency treatment for colorectal disease, the reversal of HP (HR) is infrequently performed. The aims were to evaluate the rate of HR and determine the factors predictive of achieving HR. We retrospectively reviewed the medical records of patients who underwent HP between January 2007 and June 2019 at six Hallym University-affiliated hospitals. Multivariable analysis was performed to identify which factors were independently associated with HR. In the study period, 437 patients underwent HP, and 127 (29.0%) subsequently underwent HR. Of these, 46 (35.9%) patients experienced post-HR complications. In multivariable analysis, an interval between HP and HR of > 6 months was associated with the only lower rate of post-HR complications. Multivariate analysis showed that HR was less likely in patients aged > 70 years, those with American Society of Anesthesiologists (ASA) class III or IV, elective surgery, those experiencing more than two HP-related complications, and those with a malignancy (an indication for HP). One-third of the patients underwent HR. Age > 70 years, ASA class III or IV, elective surgery, more than two HP-related complications, and malignancy were associated with a non-HR rate.

Hartmann's reversal: factors affecting complications and outcomes

AIM

Hartmann's procedure is commonly performed emergently for infectious, inflammatory, or malignant processes. Most patients historically do not undergo reversal, and those who do have been found to suffer significant morbidity. The aim of this study was to study factors associated with complications after Hartmann's reversal and to provide information and guidance to surgeons.

METHOD

A retrospective review of patients undergoing Hartmann's reversal between May 2002 and October 2017 was conducted at a tertiary medical center. Data included patient characteristics at the time of surgery and intra- and postoperative complications. Chi-square test was used for categorical variables. The Wilcoxon signed rank or t test where appropriate was used for multivariate analysis.

RESULTS

Two hundred forty-nine patients were included. Mean age at reversal was 58.8 years, and 114 (58%) were male. Sixty-two (31.8%) patients experienced a major complication following reversal. Eight (4%) patients had an anastomotic leak. Thirteen (6.67%) patients had an intra-abdominal abscess which required either IR or operative drainage. Patients who experienced a major complication were more likely to have an ASA 4 at time of reversal (14.3% vs. 4.24%, p = 0.019), liver disease (6.6% vs. 0.8%, p = 0.021), and BMI < 30 (35% vs. 17.3%, p = 0.020).

CONCLUSIONS

Nearly one-third of patients who had reversal surgery experienced a major complication. Four percent of patients undergoing reversal had an anastomotic leak, comparable to previously reported rates. Patients with ASA 4, liver disease, and BMI < 30 were at higher risk of a major complication following reversal. Patients who underwent laparoscopic reversal had no significant difference in outcomes.

AIM

What does this paper add to the literature? The decision of whether to reverse a colostomy after Hartmann's procedure. Our study aims to identify risk factors associated with complications after Hartmann's reversal to better guide surgeon's facing the dilemma of whether or not to reverse the stoma.

Endoscopic vacuum therapy for treatment of rectal stump leakage

BACKGROUND

Symptomatic rectal stump leakage (RSL) is a serious complication after discontinuity resection and requires immediate surgical, interventional, or endoscopic therapy. Re-operations are associated with high morbidity and mortality in these mostly very ill patients. Endoscopic vacuum therapy (EVT) has been established for management of anastomotic leakage; however, its effectiveness for RSL treatment has not been analyzed in detail yet.

METHODS

A retrospective analysis of patients treated with EVT for RSL between 2001 and 2018 analyzing factors predicting therapy success and duration was carried out.

RESULTS

Fifty-six patients with RSL at a median age of 66 years were included. Of these, 18 patients (32%) had been referred for EVT from external departments or institutions. RSL was associated with a relevant clinical deterioration in all patients, and 55 patients (98%) had been classified as ASA 3 and 4, preoperatively. In 9 patients (16%), additional surgical revision was necessary with initiation of EVT. In 47 patients (84%), EVT was successful and local control of the inflammatory focus was achieved. The median duration of therapy was 20 days. Two patients (4%) suffered from minor EVT-associated bleeding that was endoscopically controlled. Preoperative radiation of the pelvis was significantly associated with EVT failure (P = 0.035), whereas patient age represented a predictive factor for therapy length (P = 0.039). In 12 patients (21%), restoration of intestinal continuity was achieved in the further course.

CONCLUSIONS

We present the first specific series on EVT for RSL. EVT for RSL was shown to be an effective and safe minimal-invasive treatment option, avoiding surgical revision in the majority of patients.

Timing of colostomy reversal following Hartmann's procedure for perforated diverticulitis

AIM

Hartmann's procedure is the surgical treatment of choice for perforated acute diverticulitis. Hartmann's reversal (HR) that is performed at a later stage may be challenging. The optimal timing for HR is still a subject for controversy. The aim of this study is to assess whether the timing of HR affects surgical outcome.

PATIENTS AND METHODS

A retrospective-cohort multi-center study was conducted, including all patients who underwent HR for acute diverticulitis from January 2004 to June 2015 in 5 medical centers. Patient data included demographics, surgical data and post-operative outcome.

RESULTS

One hundred and twenty-two patients were included in the database. Median time from Hartmann's procedure to reversal was 182.7 days, with the majority of patients (76 patients, 62.2%) operated 60 to 180 days from the Hartmann's procedure. Fifty-seven patients (46.7%) had post-operative complications, most commonly wound infections (27 patients, 22.1%). Receiver operating characteristic (ROC) curve and a propensity score match analysis (P=0.43) correlating between days to HR from the index procedure showed no specific cut-off point regarding post-operative complications (P=0.16), Major (Clavien-Dindo score of 3 or more) complications (P=0.19), Minor (Clavien Dindo 1-2) and no complications (P=0.14). Median length of stay was 10.9 days (range 3-90) and Pearson correlation failed to demonstrate a correlation between timing of surgical intervention and length of stay (P=0.4).

CONCLUSION

Hartmann's Reversal is a complex surgical procedure associated with high rates of complications. In our series, timing of surgery did not affect surgical complications rate or severity or the length of hospital stay.

Association of Timing of Colostomy Reversal With Outcomes Following Hartmann Procedure for Diverticulitis

Importance

The Hartmann procedure (end colostomy) remains a common operation for diverticulitis requiring surgery. However, the timing of subsequent colostomy reversal remains widely varied, and the optimal timing remains unknown.

Objective

To investigate the association of the timing of colostomy reversal with operative outcomes.

Design, Setting, and Participants

This retrospective analysis of the Healthcare Cost and Utilization Project State Inpatient Databases for California, Florida and Maryland included patients with colostomy for diverticulitis linked to their colostomy reversal. Patients with readmissions between the index surgery and reversal were excluded, leaving a final cohort of 1660 patients. Data were collected from January 1, 2010, to December 31, 2016, and analyzed from December 1, 2017, through May 31, 2018.

Exposures

Patients were divided based on timing of colostomy reversal following the index surgery into early (45-110 days), middle (111-169 days), and late (≥170 days) reversal timing.

Main Outcomes and Measures

Primary outcomes of interest after reversal included mortality, morbidity, and readmissions and were compared among all groups using logistic regression adjusted for comorbidities and age.

Results

In total, 7165 patients with at least 1 year of follow-up were identified, and 2028 (28.3%) underwent reversal within 1 year. Of patients who underwent reversal within 1 year, 1660 had no readmissions before reversal (860 men [51.8%]; median age, 61 years [interquartile range {IQR}, 51-70 years]). The median time to reversal was 129 days (IQR, 99-182 days). On multivariable analysis, patient characteristics associated with early reversal included being 60 years or younger (odds ratio [OR], 1.31; 95% CI, 1.00-1.70; P = .0497), white race (OR, 1.32; 95% CI, 1.05-1.67; P = .02), and private insurance vs Medicaid (OR, 2.45; 95% CI, 1.67-3.60; P < .001). Mortality, transfusion, ileus, and major complications were not significantly different among the reversal timing groups. However, prolonged length of stay (OR, 1.62; 95% CI, 1.19-2.21; P = .002) and 90-day readmissions (OR, 1.61; 95% CI, 1.18-2.22; P = .003) were significantly more likely in the late vs early timing groups.

Conclusions and Relevance

Less than one-third of patients undergo colostomy reversal within 1 year after end colostomy for diverticulitis, and reversal timing is associated with socioeconomic disparities. In selected patients with an uncomplicated course, improved outcomes are associated with earlier reversal, and colostomy reversal is safe as early as 45 to 110 days after the initial procedure.

Outcomes of Hartmann's procedure and subsequent intestinal restoration. Which patients are most likely to undergo reversal?

BACKGROUND

Aim of the study was to describe characteristics and outcomes of Hartmann's procedure (HP) and subsequent intestinal restoration.

METHODS

Retrospective study including all patients who underwent HP over a period of 16 consecutive years. We propose a classification and regression tree for a more accurate view of the relationship between the variables related to intestinal restoration and their weighting in the decision to reverse HP.

RESULTS

533 patients were included. Overall morbidity rate of HP was 53.5% and mortality 21.0%. Overall morbidity of the intestinal continuity reconstruction was 47.3% and mortality 0.9%. Patients with a benign disease, aged under 69 years and with low comorbidity, had an 84.4% probability of undergoing intestinal reconstruction.

CONCLUSIONS

HP is associated with high morbidity and mortality. Restoration of intestinal continuity involves minor, but frequent, morbidity and a low mortality rate. Age and comorbidities can decrease, and even override, the decision to reverse HP.

COLOSTOMY CLOSURE: RISK FACTORS FOR COMPLICATIONS

Background

: The restoration of intestinal continuity is an elective procedure that is not free of complications; on the contrary, many studies have proven a high level of morbidity and mortality. It is multifactorial, and has factors inherent to the patients and to the surgical technique.

Aim

: To identify epidemiological features of patients that underwent ostomy closure analyzing the information about the surgical procedure and its arising complications.

Method

: It was realized a retrospective analysis of medical records of patients who underwent ostomy closure over a period of seven years (2009-2015).

Results

: A total of 39 patients were included, 53.8% male and 46.2% female, with mean age of 52.4 years. Hartmann´s procedure and ileostomy were the mainly reasons for restoration of intestinal continuity, representing together 87%. Termino-terminal anastomosis was performed in 71.8% of cases, by using mainly the manual technique. 25.6% developed complications, highlighting anastomotic leakage; there were three deaths (7.6%). The surgical time, the necessity of ICU and blood transfusion significantly related to post-operative complications.

Conclusion

: It was found that the majority of the patients were male, with an average age of 52 years. It was observed that the surgical time, the necessity of blood transfusion and ICU were factors significantly associated with complications.

Reversal of Hartmann's procedure: a single-centre experience of 533 consecutive cases

AIM

Hartmann's procedure (HP) is common. However, restoration of intestinal continuity is not so frequent. The aim of this study was to determine predictive factors which might influence outcomes following the reversal of HP.

METHOD

All consecutive patients who underwent elective and emergency HP in a single institution between January 1999 and December 2014 were included. Data concerning patient, disease and treatment features were collected. Univariate and multivariate binary logistic regression models were used to determine prognostic factors.

RESULTS

A total of 533 consecutive patients underwent HP over the 16-year period. Factors that were associated with a higher probability of reversal were age (< 69 years), American Society of Anesthesiologists (ASA) grade (I or II), indication for HP (likelihood of anastomotic leakage) and length of rectal stump reaching or exceeding the sacral promontory. A reduced probability of intestinal reconstruction was associated with anal incontinence, Stage IV cancer, postoperative transfusion or elective surgery.

CONCLUSION

Age, ASA grade, the indication for HP, the length of rectal stump, anal incontinence, tumour stage, postoperative transfusion and elective surgery determine the probability of reversal.

Considerations for Hartmann's reversal and Hartmann's reversal outcomes-a multicenter study

PURPOSE

Hartmann's procedure is commonly practiced in emergent cases with the restoration of bowel continuity planned at a second stage. This study assessed the rate of restorations following Hartmann's procedure and evaluated factors affecting decision-making.

METHODS

Data on patient demographics, comorbidities, causes for Hartmann's procedure, reversal rate, and complications were collected in a multicenter retrospective cohort study of patients who underwent Hartmann's procedure in five medical centers.

RESULTS

Six hundred forty patients underwent Hartmann's procedure for diverticular disease (36.1%), obstructing malignancy (31.8%), benign obstruction (5%), and other reasons (23.1%). Overall, 260 (40.6%) patients underwent subsequent restoration of bowel continuity. One hundred twenty-one (46.5%) patients had post-reversal complications, with an average Clavien-Dindo score of 1.4 and a mortality rate of 0.77%. Decision to avoid reversal was mostly related to comorbidities (49.7%) and metastatic disease (21.6%). Factors associated with the decision to restore bowel continuity included male gender (P = 0.02), patient age (62.3 years in Hartmann's reversal patients vs 73.5 years in non-reversal patients; P < 0.0001), number of comorbidities (1.1 vs 1.58; P < 0.001), average Charlson score (1.93 vs 3.44; P < 0.001), and a neoplastic etiology (P < 0.0001). A sub-analysis excluding all patients who died in the 30 days following Hartmann's procedure showed similar factors associated with ostomy closure.

CONCLUSION

Many patients do not have restoration of bowel continuity after undergoing Hartmann's procedure. Hartmann's reversal is associated with a significant postoperative morbidity. Surgeons and patients should be aware of the possibility that the colostomy might become permanent.
