Restoration of intestinal continuity following Hartmann's procedure: the Lothian experience 1987-1992

Comparison of the risk of postoperative wound infection in patients with rectal cancer by laparoscopic versus open Hartmann's surgery

Traditional Hartmann surgery is used when the patient is in an acute case where it might not be safe to carry out a one‐stage intestinal anastomosis. Laparoscopy has been extensively applied in the treatment of large intestine, which can significantly improve both short‐ and long‐term outcomes. While randomized, controlled studies and reviews have shown that laparoscopy is superior to that of open‐access colectomy, the impact of Hartmann's surgery on postoperative site infections has not been studied. The purpose of this study is to summarize the existing evidence to show that laparoscopy is better than open operation in the area of injury. Methods The Embase, PubMed and Cochrane Libraries were searched from the moment the database was created until November 2023. For binary results, the odds ratio was estimated, and a weighted average of consecutive results was calculated. Our findings indicate that there is a lower risk for SSIs after laparoscopic approach surgery than an open‐access procedure (OR, 0.26; 95% CI, 0.10, 0.69, p  = 0.006); Laparoscopy was associated with a reduction in the risk of dying after surgery (OR, 0.50; 95% CI, 0.30, 0.84, p  = 0.009); The operation time was not significantly different in open and laparoscope (MD, 12.23; 95% CI, −5.63, 30.09, p  = 0.18); laparoscopy was used to lower the incidence of SSI after surgery and to lower the mortality rate after surgery than by open‐access surgery. However, the time of operation did not differ significantly among the two methods. However, further controlled trials will need to be carried out to verify the results.

Hartmann's Reversal is More Complex Than Elective Left Colectomy

BACKGROUND

Hartmann's reversal (HR) is associated with significant technical complexity and morbidity. The decision to perform HR is difficult and up to 50% of patients with colostomies do not undergo a reversal. To better guide surgeons and patients with this decision, we sought to assess the surgical risks and outcomes of HR as compared to elective left colectomy (LC).

METHODS

We conducted a retrospective analysis of a prospective database at a tertiary medical center. Patients undergoing elective Hartmann's reversal and left colectomy between January 2014 and November 2021 were identified. We compared preoperative variables, intraoperative events, and short-term postoperative outcomes.

RESULTS

135 patients were identified: 30 HR and 105 LC. There were no significant differences in demographics or preoperative comorbidities between HR and LC. There were more open and fewer robotic cases in HR (23.3% vs 2.9%, P < .0001; 46.6% vs 76.0%, P < .01). Total operative time was significantly longer in HR than LC (261.8 vs 211.7 minutes, P = .02). There was a significantly higher percentage of intraoperative complications in HR (13.3% vs 1.9%, P < .01). There was a significantly higher rate of minor postoperative complications in HR than LC (46.7% vs 26.7%, P = .04), but not major (6.7% vs 5.8%, P = .85). Time to first flatus/bowel movement was significantly longer in HR than LC (3.6 vs 2.5 days, P < .001).

CONCLUSION

Hartmann's reversal is a more technically challenging operation than elective left colectomy and is associated with significantly higher rates of intraoperative and minor postoperative complications. Future studies should focus on mitigating these risk factors to optimize patient outcomes.

Hartmann's Reversal: Controversies of a Challenging Operation

PURPOSE

Hartmann's reversal is a complex operation with a high morbidity rate. Minimally invasive surgery has been used to reduce the impact of surgery on fragile patients. The aim of this comparative study is to look at the results of Hartmann's reversal procedures with different approaches.

METHODS

All the patients who underwent Hartmann's reversal were collected retrospectively (124 cases). Sixty-four patients (50.4%) had an open operation, 6 cases (5%) were treated with a conventional laparoscopic approach, 34 patients (28.1%) underwent single incision laparoscopic surgery (SILS), and 20 (16.5%) required other additional trocars.

RESULTS

SILS operations were slightly longer than the open procedures (175 min vs 150 min), with the same rate of postoperative complications and reoperations (p = 0.83 and p = 0.42), but with a shorter hospital stay (5 days p = 0.007). Age (p = 0.03), long operative time (p = 0.01), and ASA score (p = 0.05) were identified as independent factors affecting postoperative morbidity. The grade of adhesions caused a longer operative time (p = 0.001) and a higher risk of conversion (p < 0.001), and short rectal stump increased the risk of protective loop ileostomy (p = 0.008). Patients with grade 2-3 of adhesions had a longer length of stay (p = 0.05).

CONCLUSIONS

Minimally invasive procedures had a shorter hospital stay and did not show any increase in morbidity rate when compared with open cases. Age, longer operative time, and ASA score increased the risk of postoperative complications. Furthermore, patients with a short rectal stump had a higher chance of having a defunctioning ileostomy.

Reversal of left-sided colostomy utilizing single-port laparoscopy a multicenter European audit and overview of the literature

Background

Stoma reversal surgery can result in considerable morbidity and even mortality. Feasibility of utilizing single-port laparoscopy through the stoma fenestration have been shown before. Aim of the present observational study is to evaluate multicenter experiences of single-port reversal of left-sided colostomy (SPRLC) throughout Europe and to provide an overview of available literature on this topic.

Methods

All patients undergoing SPRLC in four different teaching hospitals throughout Europe are included. Primary outcome was 30-day postoperative complication rate. Secondary outcomes were postoperative length of stay (LOS), single-port success rate and conversion rates. Appraisal of the available literature in PubMed was performed.

Results

Of 156 SPRLC procedures, 98.7% of them were technically successful and 71.8% were without postoperative complications. No postoperative mortality was encountered. Superficial site infection occurred in 14.7%, anastomotic leakage in 3.9% and major complications in 8.3%. Median LOS was 4.0 days (1–69), single-port success rate was 64.7%, 12.8% and 21.2% (33/154) were converted to an open and multiport laparoscopic procedure, respectively. Literature shows equally favorable results in 131 patients divided over 5 cohorts with morbidity ranging from 0 to 30.4% and mortality from 0 to 2.2% and median LOS of 4–8 days.

Conclusion

This study confirms the safety, feasibility and favorable results of the use of single-port approach in the reversal of left-sided colostomy in different centers in Europe with laparoscopic experienced colorectal surgeons. The available literature on this topic support and show equally favorable results using single-port laparoscopy for left-sided colostomy reversal surgery.

Laparoscopic Versus Open Hartmann Reversal: A Case-Control Study

Background

Laparoscopic reversal of Hartmann's procedure (LHR) offers reduced morbidity compared with open Hartmann's reversal (OHR). The aim of this study is to compare the outcome of laparoscopic versus open Hartmann reversal.

Materials and Methods

Thirty-four patients who underwent Hartmann reversal between January 2017 and July 2019 were evaluated. Patients underwent either LHR (n = 17) or OHR (n = 17). Variables such as numbers of patients, patient's age, sex, body mass index (BMI), comorbidities, ASA (American Society of Anesthesiology) score, indication for previous open sigmoid resection, mean operation time, rate of conversion to open surgery, length of hospital stay, mortality, and morbidity were retrospectively evaluated.

Results

The two groups of patients were homogeneous for gender, age, body mass index, cause of primary surgery, time to reversal, and comorbidities. In 97% of the cases, HP was done by open surgery. Our data revealed no difference in mean operation time (LHR: 180.5 ± 35.1 vs. OHR: 225.2 ± 48.4) and morbidity rate, although, in OHR group, there were more severe complications. Less intraoperative blood loss (LHR: 100 ± 40 mL vs. OHR: 450 ± 125 mL; p value <0.001), shorter time to flatus (LHR: 2.4 days vs. OHR: 3.6 days; p value <0.021), and shorter hospitalization (LHR: 4.4 vs. OHR: 11.2 days; p value <0.001) were observed in the LHR group. Mortality rate was null in both groups. Discussion. LHR is feasible and safe even for patients who received a primary open Hartmann's procedure. We suggest careful patient's selection allowing LHR procedures to highly skilled laparoscopy surgeons.

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.

Laparoscopic versus Open End Colostomy Closure: A Single-center Experience

The aim of this study was to review our experience with laparoscopic end colostomy closure. A retrospective review of a prospectively entered database was performed. Proportions and continuous variables were compared using the Fisher's exact and the Mann-Whitney U tests, respectively. Within the study period, 53 patients underwent closure of end colostomies. The main reasons for the colonic resections were perforated diverticulitis (52.7%) and neoplasms (20.8%). In 28 patients (53%), laparoscopic closure (LC) was attempted. Demographics did not differ between the attempted LC and the primary open closure (OC) group. The conversion rate from an LC to an OC was 50 per cent (14 of 28), mostly as a result of adhesions (71.4%). Hospital length of stay (HLOS) was significantly longer for the OC than with the attempted LC group (15.4 ± 11.9 days vs 11.3 ± 8.5 days, P = 0.046). The overall complication rate was not different between the completed LC and the OC groups (43 vs 56%, P = 0.634). The majority of complications detected (91.1%) were minor and could be treated conservatively. The role of laparoscopy to close end colostomies is questionable, because the conversion rate is high. However, a shorter HLOS can be expected when laparoscopy is successful. To reduce morbidity resulting from prolonged operation times, it is crucial to convert early and pre-emptively if hostile adhesions are found.

Total Laparoscopic Reversal of Hartmann's Procedure

Hartmann's procedure is still performed in those cases in which colorectal anastomosis might be unsafe. Reversal of Hartmann's procedure (HR) is considered a major surgical procedure with a high morbidity (55 to 60%) and mortality rate (0 to 4%). To decrease these rates, laparoscopic Hartmann's reversal procedure was successfully experienced. We report our totally laparoscopic Hartmann's reversal technique. Between 2004 and 2010 we performed 27 HRs with a totally laparoscopic approach. The efficacy and safety of this technique were demonstrated evaluating the operative data, postoperative complications, and the outcome of the patients. There were no open conversions or major intraoperative complications. Anastomotic leaking occurred in one patient requiring an ileostomy; one patient needed a blood transfusion and one had a nosocomial pneumonia. The mean postoperative hospitalization was 5.7 days. Laparoscopic HR is a feasible and safe procedure and can be considered a valid alternative to open HR.

Trans-stomal single-port laparoscopic Hartmann's reversal is an efficacious and efficient procedure: a case-controlled study

BACKGROUND

Hartman's reversal remains challenging and is associated with a widely variable success rate. In a previous study, we reported that laparoscopy may lower the mortality and morbidity rates of the procedure. The aim of the current study was to assess the operative results of single-port laparoscopic Hartmann's reversal (SP-HR) as compared to the more standard, multi-port laparoscopic variant (MP-HR).

METHODS

We performed a retrospective, non-randomized, case-controlled study of 44 consecutive patients who had SP-HR (Group A) compared to 44 patients who had MP-HR (Group B). The study was conducted in a high-volume colorectal unit in a 1200-bed university affiliated hospital, The Poissy-Saint Germain Medical Complex, France.

RESULTS

Preoperative patients' characteristics (sex, body mass index, American Society of Anesthesiologists status, prior surgery, comorbidities, colonic disease) were comparable in both groups. The conversion rate was 13.6% and 4.5% in Group A and in Group B, respectively (p = 0.084) and consisted of placement of any additional ports. Conversion to open surgery did not occur in any patient in either group (p = 1). Mean operative time was shorter in Group A than in in Group B, (105 vs. 155 min; p = 0.0133). The mortality rate was 2.2% in Group A and 0% in Group B (p = 0.3145). The overall morbidity rate was 11.4% in Group A and 18.2% in Group B (p = 0.5344). The median length of hospital stay was significantly shorter in Group than in Group B (4.8 vs. 6.8 days; p = 0.0102).

CONCLUSIONS

The SP-HR technique was found to be safe and efficient. It compares favorably with MP-HR. Moreover, indirect cost savings could be induced by the reduction in the length of hospital stay.

Identification of risk factors for morbidity and mortality after Hartmann's reversal surgery - a retrospective study from two French centers

Hartmann’s reversal procedures are often fraught with complications or failure to recover. This being a fact, it is often difficult to select patients with the optimal indications for a reversal. The post-recovery morbidity and mortality rates in the literature are heterogeneous between 0.8 and 44%. The identification of predictive risk factors of failure of such interventions would therefore be very useful to help the practitioner in his approach. Given these elements, it was important to us to analyze the practice of two French university hospitals in order to highlight such risk factors and to allow surgeons to select the best therapeutic strategy. We performed a bicentric observational retrospective study between 2010 and 2015 that studied the characteristics of patients who had undergone Hartmann surgery and were subsequently reestablished. The aim of the study was to identify factors influencing morbidity and postoperative mortality of Hartmann’s reversal. Primary outcome was complications within the first 90 postoperative days. 240 patients were studied of which 60.4% were men. The mean age was 69.48 years. The median time to reversal was 8 months. 79.17% of patients were operated as emergency cases where the indication was a diverticular complication (39.17%). Seventy patients (29.2%) underwent a reversal and approximately 43% of these had complications within the first 90 postoperative days. The mean age of these seventy patients was 61.3 years old and 65.7% were males. None of them benefited from a reversal in the first three months. We identified some risk factors for morbidity such as pre-operative low albuminemia (p = 0.005) and moderate renal impairment (p = 0.019). However, chronic corticosteroid use (p = 0.004), moderate renal insufficiency (p = 0.014) and coronary artery disease (p = 0.014) seem to favour the development of anastomotic fistula, which is itself, a risk factor for mortality (p = 0.007). Our study highlights an important rate of complications including significant anastomotic fistula after Hartmann’s reversal. Precarious nutritional status and cardiovascular comorbidities should clearly lead us to reconsider the surgical indication for continuity restoration.

Laparoscopic reversal of Hartmann's procedure: A single-center experience

INTRODUCTION

Laparoscopic reversal of Hartmann's procedure (LHR) is considered a technically complex major surgical procedure. We present a retrospective analysis of a single-institution experience that assesses the treatment patterns and outcomes of patients who underwent LHR.

MATERIALS AND SURGICAL TECHNIQUE

The study involved patients who underwent LHR between January 2004 and December 2017. All patients had previously undergone a conventional Hartmann's procedure for acute complicated diverticulitis or cancer. Patients were placed in a supine position with their legs spread apart and their left arm out to the side. Access into the abdomen was obtained through open laparoscopy, with a 12-mm trocar for a 30° laparascope inserted at the periumbilical site. We placed between three and five trocars depending on the level of operative difficulty encountered. The first surgical step was to dissect any existing adhesions, and then rectal mobilization was systematically performed to ensure the feasibility of the end-to-end anastomosis and to avoid bladder injury. The stoma was mobilized on the level of the abdominal wall and then freed from the fascia. We used a circular stapler to reestablish a tension-free anastomosis. Over 13 years, 20 patients underwent LHR. No patient required a temporary colostomy or ileostomy.

DISCUSSION

Reversal of Hartmann's procedure involves high operative morbidity and mortality, and usually only relatively young and healthy patients are eligible for reversal. Our results are consistent with previously published literature regarding the advantages of LHR compared to the conventional technique. However, high-level evidence is still needed.

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.

The Challenges of the Hartmann's Rectal Stump Reversal: A Clinical Audit and Review of the Literature

Background:

Hartmann's procedure is performed in patients who are not candidates for immediate reestablishment of colonic continuity. A shrunken rectal stump poses a great challenge at the time of its reversal.

Objective:

To determine the factors [level of inferior mesenteric artery (IMA) ligation and duration prior to Hartmann's reversal] contributing to a shrunken rectal stump. The value of imaging and success rate of the technique used in the Hartmann's reversal were also assessed.

Methods:

A retrospective analysis of 36 patients who underwent Hartmann's procedure and reversal between 2012 and 2014 was performed. Patient demographic profile, initial pathology, operation setting, level of IMA ligation, complications, duration prior to reversal, imaging modality, state of rectal stump, outcome, and reversal technique were documented.

Results:

Thirty-six patients were considered for reversal of Hartmann's procedure. In 95.5% of subjects who underwent a high IMA ligation, proximal rectum stricture and short, shrunken rectal stumps were noted. Patients who underwent reversal after 6 months had a significant incidence of a short shrunken rectal stump (n = 19; 82.6%). The percentage of successful outcomes in the reversal of the short rectal stump using the stapling technique was 93.8% (n = 27). Twenty-six patients who underwent barium enema correlated strongly with the operation findings.

Conclusion:

High ligation in Hartmann's procedure contributes to a short shrunken rectal stump. The duration prior to reversal of more than 6 months correlates with a shrunken rectal stump. Preoperative imaging evaluation serves as a good predictor for the length of the rectal stump. A staples anastomotic technique shows good outcome.

Emergency Hartmann's Procedure and Its Reversal: A Totally Laparoscopic 2-Step Surgery for the Treatment of Hinchey III and IV Diverticulitis

BACKGROUND

Hartmann's procedure (HP) followed by reversal restoration is the first choice for treatment of diffuse diverticular peritonitis. There is no unanimous consensus regarding the use of laparoscopy to treat the same condition.

METHODS

Data from 60 patients with diverticular diffuse peritonitis who underwent urgent HP followed by laparoscopic reversal were retrospectively analyzed. Patients were divided into 2 groups according to the open or laparoscopic HP (OHP, 24 patients; LHP, 36 patients). Outcomes were measured in terms of functional recovery, morbidity, mortality, and length of hospital stay.

RESULTS

HPs showed no differences among the groups in terms of operative time, blood loss, and length of intensive care unit stay. Overall morbidity was significantly lower in LHP than in OHP, corresponding to 33.3% and 66.7% respectively ( P = .018). The incidence of both surgical and medical complications was higher in OHP than in LHP (41.7% vs 22.2% [ P = .044] and 45.8% vs 24.3% [ P = .023], respectively). Mortality was 16.6% for each group. LHP showed a faster return to bowel movements and a shorter hospital stay than OHP. The secondary intestinal reversal was possible in 92% of cases, successfully completed laparoscopically in 91.3%. No patients of LHP group required a conversion to open intestinal reversal.

CONCLUSION

LHP for treatment of diverticular diffuse peritonitis showed significantly lower morbidity, faster recovery, shorter hospital stay, and higher rates of successful laparoscopic reversal when compared with OHP.

Case Selection for Laparoscopic Reversal of Hartmann's Procedure

BACKGROUND

Laparoscopic reversal of Hartmann's procedure offers reduced morbidity compared with open surgery while improving reversal rates. However, it is one of the most technically challenging operations in minimally invasive colorectal surgery, with further < 20% of the reversal procedures being attempted laparoscopically. Complications related to late conversion to open surgery may suggest a selective use of the laparoscopic approach for Hartmann's reversal in a subgroup of patients: The aim of this study is to systematically investigate the literature to identify the ideal case for a laparoscopic approach.

MATERIALS AND METHODS

Data were extracted from a systematic review of the literature of Medline, Scopus, Web of Science, Embase, and the Cochrane Central Register of controlled trials. Subgroup analysis to identify suitable patients for laparoscopic surgery included age at surgery, body mass index, American Society of Anesthesiologists status, indication for the index Hartmann's procedure (HP), interval time to reversal from the index HP, conversion to open surgery, and temporary ileostomy rate.

RESULTS

A total of 862 patients were included, with 403 cases performed laparoscopically. Conversion to open surgery occurred in 65 patients (mean 16.1%). The indication for the HP showed a trend toward more benign patients included in the laparoscopic group, and the interval time between the index Hartmann's procedure and its reversal was significantly shorter in the laparoscopic group with a trend toward a higher rate of temporary ileostomy in patients undergoing an open procedure.

CONCLUSIONS

Patients' selection can explain these differences, with more complex disease operated via an open approach. Nevertheless, future studies are needed to demonstrate an increasing number of reversals attempted laparoscopically in high-volume centers.

Risk Factors for Surgical Site Infection in Open and Laparoscopic Hartmann Closure: A Multivariate Analysis

BACKGROUND

Hartmann reversal is a high-morbidity procedure. The aim of this study is to identify risk factors for surgical site infection (SSI) in the era of laparoscopy.

MATERIALS AND METHODS

A query of the National Surgical Quality Improvement Program database was done. Patients undergoing open or laparoscopic Hartmann reversals were identified. Risk factors for and the incidence of SSI were assessed in both groups.

RESULTS

A total of 7970 patients were identified and 1431 (18%) were done laparoscopically. The SSI rate in the overall population was 13.6%, with 14.9% in those undergoing open surgery and 8% with laparoscopic procedures. Obese patients and smokers had the highest incidences of SSI (18% and 17.5%, respectively). Open surgery (odds ratio=1.8, P<0.001) and obesity (odds ratio=1.6, P<0.001) significantly correlated with higher SSI rates.

CONCLUSIONS

Patients undergoing Hartmann closure are at risk for SSI. Our findings indicate that laparoscopy can significantly reduce SSI, particularly in obese patients.

Comparison of Short-term Outcomes After Laparoscopic Versus Open Hartmann Reversal: A Case-matched Study

PURPOSE

The aim of this study is to compare short-term outcomes of laparoscopic versus open Hartmann reversal.

MATERIALS AND METHODS

Patients who underwent Hartmann reversal between January 2005 and September 2014 were identified and matched for age, sex, body mass index, American Society of Anesthesiologists score, and creation of diverting ileostomy to open counterparts. Patient characteristics and postoperative outcomes (30 d) were evaluated.

RESULTS

Eighteen patients with laparoscopic Hartmann reversal were matched to 18 open patients. There were no differences between laparoscopic versus open groups in terms of operative time (157.7±52.2 vs. 151.5±49.3 min, P>0.05) or overall complication rates [6 (33.3%) vs. 6 (33.3%) (P>0.05)]. No anastomotic leaks or mortality occurred in either group. However, the laparoscopic group was associated with significantly decreased estimated blood loss (114±103 vs. 217±125 mL, P<0.05), faster return of bowel function (3.2±0.6 vs. 4±0.6 d, P<0.05), and reduced hospital stay (5.4±3.1 vs. 8.3±4.8 d, P<0.05).

CONCLUSIONS

Laparoscopic Hartmann reversal can be safely performed with better short-term outcomes in carefully selected patients.

Reversal of the Hartmann's procedure: A comparative study of laparoscopic versus open surgery

BACKGROUND:

The Hartmann's operation, although less frequently performed today, is still used when initial colonic anastomosis is too risky in the short term. However, the subsequent procedure to restore gastrointestinal continuity is associated with significant morbidity and mortality.

PATIENTS AND METHODS:

The review of an institutional review board (IRB)-approved prospectively maintained database provided data on the Hartmann's reversal procedure performed by either laparoscopic or open technique at our institution. The data collected included: demographic data, operative approach, conversion for laparoscopic cases and perioperative morbidity and mortality.

RESULTS:

Over a 14-year period from January 1997 to August 2011, 74 Hartmann's reversal procedures were performed (laparoscopic surgery—49, open surgery—25). The average age was 55 years for the laparoscopic and 57 years for the open surgery group, respectively. Male patients represent 61% of both groups. There was no significant difference in operative time between the two groups (149 min vs 151 min; P = 0.95), and there was a tendency to lower morbidity (3/49—7.3% vs 4/25—16%; P = 0.24) in the laparoscopic surgery group. In the laparoscopic group, eight patients (16.3%) were converted to open surgery, mostly due to severe adhesions. The length of hospital stay was significantly shorter for the laparoscopic group (5 days vs 7 days; P = 0.44).

CONCLUSIONS:

The Hartmann's reversal procedure can be safely performed in the majority of the cases using a laparoscopic approach with a low morbidity rate and achieving a shorter hospital stay.

Laparoscopic versus open Hartmann's reversal: a systematic review and meta-analysis

BACKGROUND

Hartmann's reversal is a major surgical procedure with consistent morbidity and mortality rates. Laparoscopy has been extensively applied to colorectal surgery providing significant benefits on short- and long-term outcomes. We performed a meta-analysis of the current evidence comparing the short-term outcomes of laparoscopic Hartmann's reversal (LHR) to open Hartmann's reversal (OHR).

METHODS

A systematic search of Medline, Scopus, Web of Science, Embase, and the Cochrane database was performed. Comparative studies reporting short-term outcomes of LHR versus OHR with an intention-to-treat analysis were considered for eligibility. Primary outcome was 30-day morbidity. Secondary outcomes were 30-day mortality, 30-day reoperations, length of hospital stay (LOS), operating time, and estimated blood loss.

RESULTS

Thirteen studies comparing 862 patients (403 LHR vs 459 OHR) were included. There was no difference in mortality, while LHR was associated with a reduced overall postoperative 30-day morbidity (OR, 0.24; 95 % CI, 0.16 to 0.34). Wound infections (OR, 0.54; 95 % CI, 0.35 to 0.85) and ileus (OR, 0.47; 95 % CI, 0.25 to 0.87) were more common after OHR. LOS was shorter in the laparoscopic group as it was the time to flatus. Meta-regression analysis showed that the results were independent from potential effect modifiers.

CONCLUSIONS

LHR has less short-term complications than OHR in terms of overall morbidity, wound infection, and postoperative ileus. LOS is shorter in the LHR group, while no significant difference exists in the operating time. Randomized controlled trials are needed to confirm these findings on unbiased populations.

Reversal of Hartmann's procedure utilizing single-port laparoscopy: an attractive alternative to laparotomy

BACKGROUND

Complications after restoration of intestinal continuity (RIC) following Hartmann's procedure occur frequently and are often serious. These complications result in a reported morbidity of 4-30 % and a reported mortality of 10-14 %. Reducing the amount of surgical trauma accompanying abdominal access seems an attractive tool to reduce perioperative morbidity. This possibility is offered by single-port Hartmann's reversal (SPHR) through the colostomy site.

METHODS

The purpose of the present prospective study was to compare outcome of SPHR to a retrospectively collected historical control group of conventional open Hartmann's reversal (OHR). All patients undergoing RIC between January 1, 2009, and January 1, 2014, were included in the present study. Operation time, morbidity and hospital stay were assessed. Postoperative surgical results of SPHR and OHR were the main outcome of the study.

RESULTS

During the study period, 41 patients (M/F = 23:18; median age 58 (26-85) years) were included in the present study. Sixteen patients underwent OHR; 25 patients underwent SPHR. No mortality was observed in the present series. Median operation time was similar between groups [184 (29-377) vs. 153.5 (73-332) min]. Hospital stay was significantly shorter in the SPHR group [16 (4-74) vs. 4 (1-34) days, p < 0.05]. The number of complications was significantly lower in the SPHR group (33 vs. 10, p < 0.05); furthermore, significantly less patients had severe complications (Clavien-Dindo III or higher) in the SPHR group (7/33 vs. 1/10). Less wound-related complications occurred in the SPHR group (12 vs. 5, p < 0.05).

CONCLUSION

This study confirms recent findings in the literature regarding the safety and feasibility of SPHR. SPHR seems to be an attractive alternative to OHR.

Surgical outcome in patients undergoing reversal of Hartmann's procedures: a multicentre study

AIM

Recent evidence has suggested that a laparoscopic rather than an open approach to reversal of Hartmann's procedure (ROH) may be associated with fewer complications. Much of the data for comparison are historical or based on small case series. The aims of this study were to determine the morbidity and mortality of ROH in 10 hospitals in the modern era and to identify risk factors for complications.

METHOD

A multicentre study of patients undergoing ROH (2007-2013) was performed. Data were collected retrospectively from perioperative health databases and casenotes where appropriate on patient demographics, laboratory investigations and operative details. Complications were classified as minor (I-II) or major (III-IV) based on the Clavien-Dindo criteria. Risk factors for complications were assessed by multivariate analysis with calculation of OR with 95% CI.

RESULTS

Ten hospitals in Scotland provided data on 252 patients undergoing ROH. Most operations were open (85%) with 15% started laparoscopically (conversion rate 64%). In the postoperative period, 35 (14%) patients had a major complication, including anastomotic leakage in 10 (4%) and postoperative death in one (0.4%). Patients with a complication stayed significantly longer in hospital (12 days vs 7 days, P < 0.001). On multivariate analysis, a wound complication after the original Hartmann's procedure (OR = 3.85, 95% CI: 1.08-13.75, P = 0.038) was associated with any complication after ROH, but only American Society of Anesthesiologists (ASA) grade (OR = 3.35, 95% CI: 1.38-8.09, P = 0.007) was independently associated with the development of a major complication.

CONCLUSION

ROH has a low postoperative mortality but significant morbidity. Most operations are still performed by open surgery, and in those attempted laparoscopically, the conversion rate is high.

Who gets Hartmann's reversed in a regional centre?

BACKGROUND

Many patients who undergo a Hartmann's procedure do not have their stoma reversed. We analysed parameters and co-morbidity scales to assess their accuracy in predicting likelihood of undergoing reversal.

MATERIAL AND METHODS

Retrospective analysis of 165 patients from a prospective colorectal database who were discharged home following a Hartmann's procedure at Barwon Health (Geelong, Australia), a regional centre, between 2002 and 2010. Parameters measured included age, sex, time to reversal, ICU admission and pathology results were recorded. Patients' ASA, POSSUM and Elixhauser co-morbidity scales were retrospectively analysed.

RESULTS

Reversal of Hartmann's was performed in 74/165 (45%) patients after a median of 294 days (range 70-902). Age (mean 58.5 vs 72.9 years, p < 0.001), ICU stay (34/74 vs 66/91, p < 0.001), ASA (p < 0.002), Elixhauser co-morbidity count (mean 1.14 vs 1.92, p < 0.002) and a malignant diagnosis (9/74 vs 31/91, p < 0.002) were all associated with a decreased reversal rate on univariate analysis. Age was the only parameter found to be significant on multivariate analysis. The complication rate was 23/74, with 7/74 noted to have major complications (Clavian-Dindo III-IV). Reasons for not reversing patients included age and co-morbidities, patient refusal, and malignant disease progression.

CONCLUSIONS

More than half the patients undergoing a Hartmann's procedure did not proceed to a closure of their stoma. Age was the only parameter significant in predicting those patients undergoing reversal.

Laparoscopic Reversal of Hartmann's Procedure: State of the Art 20 Years after the First Reported Case

Introduction. Aim of the present work is to review the literature to point out the role of laparoscopic reversal of Hartmann procedure. Material and Methods. Number of patients, age, sex, etiology, Hinchey classification, interval between procedure and reversal, position of the first trocars, mean operative time (min), number and causes of conversion, length of stay, mortality, complications, and quality of life were considered. Results. 238 males (52.4%) and 216 females (47.6%) between 38 and 67 years were analyzed. The etiology was diverticulitis in 292 patients (72.1%), carcinoma in 43 patients (10.6%), and other in 70 patients (17.3%). Only 7 articles (22.6%) reported Hinchey classification. The interval between initial procedure and reversal was between 50 and 330 days. The initial trocar was open positioned in 182 patients (43.2%) through umbilical incision, in 177 patients (41.9%) in right upper quadrant, and in 63 patients (14.9%) in colostomy site. The operative time was between 69 and 285 minutes. A total of 83 patients (12.1%) were converted and the causes were reported in 67.4%. The length of stay was between 3 and 12 days. 5 patients (0.7%) died. The complications concern 112 cases (16.4%). Conclusion. The laparoscopic Hartmann's reversal is safer and achieves faster positive results.

Robotic-assisted reversal of Hartmann's procedure for diverticulitis

The minimally invasive laparoscopic approach for the reversal of Hartmann's procedure (HP) has been shown to be a safe and feasible approach associated with low morbidity and fast recovery. Robotic surgery has not yet been described for HP reversal. We report the case of an 84-year-old man originally operated on in an emergency setting by conventional HP for complicated diverticulitis who underwent a robotic-assisted HP reversal. The surgical procedure and the post-operative follow-up were uneventful, with low post-operative pain, early return to bowel function, and discharge at day 3. The robotic surgery appeared to be a safe, feasible, and valuable approach for HP reversal.

Laparoscopic colorectal surgery for diverticular disease is not suitable for the early part of the learning curve. A retrospective cohort study

AIM

We evaluate the challenges of laparoscopic colorectal surgery for diverticular disease.

METHODS

Retrospective study of elective laparoscopic colorectal procedures (LCP) performed 2002-2011. The study compares LCP for Diverticular disease (S group) with both LCP for other pathology (C1 group) and open procedures for diverticular disease (C2 group). Statistical analysis was performed using Fisher's exact test, Student "t" test and Mann Whitney U-test.

RESULTS

The study included 194 LCP out of which 22 were in S group. Conversion rate in S group was 27.3% vs 9.9% in C1 group, p = 0.017. The mean operating time was significantly higher in S group (250 min) compared with 196 min in C1 group, p = 0.0004. The median length of hospital stay was 6 days in S group and 4 days in C group, p = 0.12. Both morbidities and mortality rates were not statistically different between the two groups. In the second part of the study we compare LCP with OCP performed for diverticular disease.

CONCLUSION

LCP for Diverticular disease are technically challenging and should be attempted later in the learning curve.

Should laparoscopic reversal of Hartmann's procedure be the first line approach in all patients?

BACKGROUND/AIMS

To assess if the laparoscopic reversal of Hartmann's can be attempted in all patients, without detriment to short or long-term outcomes if the patient is subsequently converted to open.

METHODS

Retrospective review of a prospectively collected database of all reversals under 8 surgeons at a single unit over 105 months, two surgeons attempting laparoscopic reversal in all patients, two pre-selecting for the laparoscopic approach and four utilising the open approach. Long-term follow-up data for re-admissions, re-operations and incisional hernia rate obtained from a postal questionnaire.

RESULTS

45 laparoscopic and 50 primary open reversals were identified. There was no difference in the mean age or previous peritonitis rate in either group. Laparoscopic conversion rate was 29% (13 patients). On intention to treat analysis, a significant difference was identified in the overall 30-day post-operative surgical morbidity (8.9% Laparoscopic-attempted vs 26.0% Open, p = 0.030). There was no difference in operating times (mean 164 vs 172 min, p = 0.896) despite the 13 patients converted to an open procedure. Mean length of stay was significantly lower in the laparoscopic-attempted group at 6.8 days (5.2-8.4) vs 14.9 days (6.4-23.7) in the open group (p = 0.001). Anastomotic leak rates were not statistically different. The median follow up was 27 months (range 6-105); 60% of patients completed a postal follow-up questionnaire. There was no difference in short-term or long-term re-admission or reoperation rates.

CONCLUSIONS

Laparoscopic reversal of Hartamann's is associated with shorter hospital stay and lower morbidity even in unselected patients. Long-term outcomes are similar.

Laparoscopic reversal of Hartmann's procedure: safety and feasibility

Aims: The present study aimed to compare the surgical outcomes of patients receiving laparoscopic reversal of Hartmann’s procedure (RHP) with those receiving open surgery.

Methods: Records of all patients with RHP performed in our unit (including laparoscopic and open surgery) between 2000 and 2012 were retrieved. Data were retrospectively reviewed and compared.

Results: Eighty-two RHPs were performed between 2000 and 2012. Thirty-five were performed with an open approach and 47 with a laparoscopic approach. Conversion rate was 28% in the laparoscopic group. There was no difference, between the two groups, in operation time or blood loss. The median length of stay was significantly shorter in the laparoscopic group (12 vs 14 days, P = 0.002) and fewer patients in the laparoscopic group had complications with post-operative paralytic ileus (2 vs 17%, P = 0.038). None of the patients in the laparoscopic group developed incisional hernia at the conclusion of follow-up, as opposed to five in the open group (0 vs 14%, P = 0.012).

Conclusion: Laparoscopic RHP is safe and feasible, with more favorable surgical outcomes, when compared with open surgery. Conversion rate is acceptable. It should be the technique of choice for patients undergoing RHP.

Hartmann reversal: obesity adversely impacts outcome

BACKGROUND

Comprehensive analyses are lacking to identify predictors of postoperative complications in patients who undergo a Hartmann reversal.

OBJECTIVE

The aim of this study is to identify predictive factors for morbidity after reversal.

DESIGN

This study is a retrospective review of prospectively collected data.

SETTINGS

The study was conducted at Cleveland Clinic Florida.

PATIENTS

Consecutive patients from January 2004 to July 2011 who underwent reversal were included.

MAIN OUTCOME MEASURES

Variables pertaining to Hartmann procedure and reversal were obtained for analyses in patients with and without postoperative complications. Univariate and multivariate analyses were performed.

RESULTS

A total of 95 patients (mean age 61 years, 56% male) underwent reversal, with an overall morbidity of 46%. Patients with and without complications had similar demographics, comorbidities, diagnoses, and Hartmann procedure intraoperative findings. Patients with complications after reversal were more likely to have prophylactic ureteral stents (61% vs 41%, p < 0.05) and an open approach (91% vs 75%, p < 0.04). Complications were associated with longer hospital stay (8.8 vs 6.9 days,p < 0.006) and higher rates of reintervention (9% vs 0%, p < 0.03) and readmission (16% vs 2%, p < 0.02). Predictors of morbidity after reversal included BMI (29 vs 26 kg/m, p < 0.04), hospital stay for Hartmann procedure (15 vs 10 days, p < 0.03), and short distal stump (50% vs 31%, p < 0.05). BMI was the only independent predictor of morbidity (p < 0.04). Obesity was associated with significantly greater overall morbidity (64% vs 40%, p < 0.04), wound infections (56% vs 31%, p < 0.04), diverting ileostomy at reversal (24% vs 13%, p < 0.05), and time between procedures (399 vs 269 days, p < 0.02).

LIMITATIONS

This study was limited by its retrospective design.

CONCLUSIONS

Hartmann reversal is associated with significant morbidity; BMI independently predicts complications. Therefore, patients who are obese should be encouraged or even potentially required to lose weight before reversal.

Low complication rate after stoma closure. Consultants attended 90% of the operations

AIM

To evaluate complications after stoma closure.

METHOD

Using a retrospective review of 997 medical records, data were collected from all patients undergoing stoma closure at the Department of Surgery P, Aarhus University Hospital, Denmark, from 1996 to 2010. Patient data after Hartmann reversal and loop-ileostomy closure were compared. Data regarding the grade of the operating surgeon and assistant were extracted.

RESULTS

Out of 997 patients, 700 (70.6%) had a loop-ileostomy closure and 172 (17.4%) had a Hartmann reversal. Postoperative mortality was 0.5%. Seven patients required re-operation (0.7%). Morbidity was registered in 31.9% of the patients, with 131 (13.1%) having early complications and 187 (18.8%) having late complications. Wound infection was the most frequent early complication, which occurred in 31 patients (3.1%). Only 10 patients (1%) had an anastomotic leak. Incisional hernia was the most frequent late complication, occurring in 92 patients (9.3%). A consultant attended 90% of the operations. Junior surgeons never performed stoma closure without supervision. Body mass index was significantly associated with the development of incisional hernia. Hartmann reversal was associated with higher rates of complications compared with loop-ileostomy closure. In patients with Hartmann reversal, stapled anastomosis was associated with stricture in 12 out of 95 cases (12.6%), whereas hand-sewn anastomosis was not associated with stricture (0 out of 64 patients; 0%; P < 0.05).

CONCLUSION

Stoma closure is associated with low rates of leakage. A favourable case mix and high degree of consultant attendance may explain the good results.

Elective sigmoid colectomy for diverticular disease. Laparoscopic vs open surgery: a systematic review

AIM

A meta-analysis of nonrandomized studies and one randomized trial was conducted to compare laparoscopic surgery with open surgery in the elective treatment of patients with diverticular disease.

METHOD

Published randomized and controlled clinical trials that directly compared elective open (OSR) with laparoscopic surgical resection (LSR) in patients with diverticular disease were identified using the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. End-points included 30-day mortality and morbidity and were compared by determining the relative risk ratio, odds ratio, and the absolute effects.

RESULTS

Eleven nonrandomized studies of 1430 patients were identified and included in the meta-analysis. There was only one randomized study, which included 104 patients. The meta-analysis suggested that elective LSR was a safe and appropriate option for patients with diverticular disease and was associated with lower overall morbidity (P = 0.01) and minor complication rate (P = 0.008).

CONCLUSION

The results of the nonrandomized study generally agreed with those of the randomized study, except for the incidence of minor complications, which was higher in both the LSR and OSR groups of the randomized study. In this study, the high overall morbidity of 42.3% reported in the LSR group is a cause for concern.

Hartmann's operation: how often is it reversed and at what cost? A multicentre study

AIM

The study evaluated the rate of reversal of Hartmann's operation after the initial surgery and its morbidity.

METHOD

A multicentre retrospective study was carried out in seven hospitals in the Valencia area of patients who underwent Hartmann's operation from 2004 to 2008. The incidence of reversal was determined.

RESULTS

Four hundred and fifty-two patients of mean age 67.5 ± 15.4 years were included, of whom 78.8% had an emergency operation. The most common diagnosis was cancer (58.6%), although diverticulitis predominated in the emergency setting. At a median follow up of 44 months, 159 (35.2%) patients had undergone reversal, including 16.6% after elective surgery and 40.4% after an emergency Hartmann's procedure (P < 0.001). The most frequent reason why reversal was not done was death (74 [25%] patients). Patients undergoing reversal were younger and had a low ASA risk. Trauma was associated with a higher rate of reversal, followed by diverticular disease. Surgery was performed at a median of 10 months. An open approach with stapled anastomosis was used in most cases. The mortality was 3.5%. Complications occurred in 45.2%, with a 6.2% rate of anastomotic leakage. Complications were associated with age, diabetes mellitus, arteriosclerosis, obesity, smoking, chemotherapy and COPD.

CONCLUSION

Hartmann's reversal was performed in a small percentage of patients, mostly including those with benign disease. It had a significant morbidity.

Technical aspects and outcome of a standardized full laparoscopic approach to the reversal of Hartmann's procedure in a teaching centre

AIM

Laparoscopic reversal of Hartmann's procedure is technically demanding. We evaluated the technical aspects and outcome of a standardized approach in a single centre and examined the feasibility of including this into training curricula.

METHOD

The procedure entails a laparoscopy for adhesiolysis and identification and mobilization of the rectal stump. Mobilization of the splenic flexure is performed if necessary, and a colorectal anastomosis is fashioned after introduction of the stapler anvil via the colostomy with intra-abdominal positioning and delivery into the proximal colonic segment to be anastomosed. The stoma is excised as the last step in the operation.

RESULTS

Forty-two patients underwent the procedure over an 8-year period with either an expert (n=21) or trainee under expert mentorship (n=21) as first operator. Intra-operative data and postoperative outcomes were evaluated by retrospective review of clinical charts and theatre records. There was a 9.5% conversion rate and 0% mortality. One patient suffered a ureteric injury, while postoperative surgical complications occurred in 7 patients (including one clinical anastomotic leakage). The mean operative time was 117 min. There was no significant difference in intra operative technical parameters or postoperative clinical consequences between procedures performed by a trained surgeon or by a trainee under mentorship.

CONCLUSION

Adherence to a standardized operative protocol and expert mentorship allows this technically demanding operation to be associated with low conversion and complication rates. The absence of any difference between procedures performed by a trainee or trained surgeon suggests that the operation can be included in training programmes for laparoscopic surgery.

Laparoscopic colostomy reversal after a Hartmann procedure: a prospective series, literature review and an argument against laparotomy as the primary approach

BACKGROUND

Open restoration of bowel continuity after a Hartmann procedure has been associated with significant morbidity, including anastomotic leak, incisional hernia, wound infections and inability to re-establish intestinal continuity. Few studies have examined the role of laparoscopy in performing a Hartmann reversal. The aim of this study was to review our laparoscopic Hartmann reversal (LHR) experience with an emphasis on intra- and postoperative adverse events.

METHODS

A prospectively collected laparoscopic colorectal database involving 3 surgeons in 4 academic centres between 1991 and 2008 was reviewed. Factors evaluated were patient demographics, diagnosis, duration of surgery, intra- and postoperative complications, recovery of bowel function and length of stay in hospital.

RESULTS

Twenty-eight consecutive patients (13 men, 15 women) with a mean age of 61.1 (standard deviation [SD] 15.3) years and a mean weight of 72.3 (SD 20.1) kg underwent LHR. The diagnosis at initial surgery was complicated diverticulitis in 19 patients (67.9%), cancer in 6 patients (21.4%) and "other" in 3 patients (10.7%). The median duration of surgery was 166.2 (SD 74.4) minutes. There were no conversions. There was 1 major intraoperative complication (bleeding; 3.6%). There were 3 postoperative complications (10.7%): 1 abscess, 1 prolonged ileus and 1 wound hematoma. Only 1 patient with an abscess required readmission. There were no observed clinical anastomotic leaks. All patients underwent successful reanastomosis. The median time to return of bowel function was 4 (interquartile range [IQR] 3-4) days. The median length of stay in hospital was 5 (IQR 3-6) days. There was no mortality.

CONCLUSION

Laparoscopic colostomy reversal after a Hartmann procedure is safe and feasible in experienced hands. It is associated with low morbidity, quick return of bowel function and short stay in hospital.

[Laparoscopic approach for intestinal passage reconstruction after Hartmann's operation: experience with 30 patients]

INTRODUCTION

Intestinal passage reconstruction after Hartmann's (PRH) operation is associated with a high morbidity and mortality of about 1%. Despite the increasing use of laparoscopy as an alternative in PRH, there is a lack of patient series at international level.

PATIENTS AND METHODS

The prospective series of patients subjected to (PRH) by laparoscopy was analysed using the demographic parameters, ASA classification, reason for primary surgery, time between initial surgery and reconstruction, operation time, conversion to open surgery, bowel rest recovery time, complications, hospital stay and follow up.

RESULTS

A total of 30 patients with a mean age of 61.5 ± 13 years were operated on using laparoscopy. The ASA classification was 1.8 ± 0.3 the BMI was 26.1 ± 2 Kg/m(2). A total of 63% were admitted due to complicated Hinchley III or IV acute diverticulitis. The interval between initial surgery and the passage reconstruction was 7.1 ± 2 months. Conversion to open surgery was necessary in three cases. The mean intestinal passage recovery was 2.1 ± 1 days and the hospital stay was 5.6 ± 1 days. The long-term complications were one mechanic ileum due to bridles and one case of anastomotic stenosis.

CONCLUSIONS

The post-Hartmann laparoscopic passage reconstruction is associated with a short intestinal motility recovery time, as well as a less prolonged hospital stay compared to an open surgery series. Randomised studies are needed to determine whether laparoscopic reconstruction is superior to the conventional technique.

Factors affecting reversal following Hartmann's procedure: experience from two district general hospitals in the UK

PURPOSE

Restoration of gastrointestinal continuity following Hartmann's procedure is a challenging task associated with significant morbidity and mortality. New strategies to avoid a stoma are not readily available in general hospitals. Knowledge of the factors related to reversal is required to develop treatment strategies and counsel patients realistically. The present study was conducted to determine the reversal rate and factors affecting Hartmann's reversal in our practice.

METHODS

This study retrospectively reviewed the medical records of patients who underwent Hartmann's procedure and its reversal in two United Kingdom District Hospitals between January 1996 and December 2005.

RESULTS

Case notes from 184 patients were reviewed. Hartmann's procedure was reversed in 51 (34.7%) of the surviving patients, with a complication rate of 37.3% and no mortality. Reversal of Hartmann's procedure was significantly related to patient age (P < 0.001), mode of admission (P = 0.003), American Society of Anesthesiologists grading (P = 0.003), Dukes' staging (P = 0.003), benign pathology (P = 0.001), and extracolonic cancer (P = 0.023).

CONCLUSIONS

Despite the challenging nature of Hartmann's reversal, colostomy closure can be achieved without mortality in a district general hospital. Familiarity with the factors associated with reversal should enable a genuine discussion with patients regarding reversal.

Laparoscopic peritoneal lavage for perforated colonic diverticulitis: a systematic review

AIM

This systematic review aimed to evaluate the efficacy, morbidity and mortality of laparoscopic peritoneal lavage for patients with perforated diverticulitis.

METHOD

We searched PubMed, EMBASE, Web of Science, the Cochrane Library and CINAHL databases, Google Scholar and five major publisher websites without language restriction. All articles which reported the use of laparoscopic peritoneal lavage for patients with perforated diverticulitis were included.

RESULTS

Two prospective cohort studies, nine retrospective case series and two case reports reporting 231 patients were selected for data extraction. Most (77%) patients had purulent peritonitis (Hinchey III). Laparoscopic peritoneal lavage successfully controlled abdominal and systemic sepsis in 95.7% of patients. Mortality was 1.7%, morbidity 10.4% and only four (1.7%) of the 231 patients received a colostomy.

CONCLUSION

There have been no publications of high methodological quality on laparoscopic peritoneal lavage for patients with perforated colonic diverticulitis. The published papers do, however, show promising results, with high efficacy, low mortality, low morbidity and a minimal need for a colostomy.

Open vs laparoscopic approach for reversal of Hartmann's procedure: a systematic review

AIM

A meta-analysis of published literature comparing open vs laparoscopic Hartmann's reversal.

METHOD

MEDLINE, EMBASE, CINAHL, PubMed and the Cochrane databases were searched from January 1993 to August 2008. The bibliography of selected trials was scrutinized and relevant references obtained. A systematic review was performed to obtain a summative outcome.

RESULTS

Eight comparative studies involving 450 patients were analysed. One hundred and ninety-three patients were in the laparoscopic and 257 in the open group. Laparoscopic reversal has a significantly reduced complication rate (z = -2.92, P < 0.01), intra-operative blood loss (z = -7.34, P < 0.001) and hospital stay (z = -3.16, P < 0.01) compared with the conventional approach. No difference in leak rates was found.

CONCLUSION

Laparoscopic reversal of Hartmann's procedure is safe, has fewer complications and shorter hospital stays. This approach may be considered for reversal, however, randomized controlled trials are required to strengthen the evidence.

Current indications and role of surgery in the management of sigmoid diverticulitis

Sigmoid diverticulitis is a common disease which carries both a significant morbidity and a societal economic burden. This review article analyzes the current data regarding management of sigmoid diverticulitis in its variable clinical presentations. Wide-spectrum antibiotics are the standard of care for uncomplicated diverticulitis. Recently published data indicate that sigmoid diverticulitis does not mandate surgical management after the second episode of uncomplicated disease as previously recommended. Rather, a more individualized approach, taking into account frequency, severity of the attacks and their impact on quality of life, should guide the indication for surgery. On the other hand, complicated diverticular disease still requires surgical treatment in patients with acceptable comorbidity risk and remains a life-threatening condition in the case of free peritoneal perforation. Laparoscopic surgery is increasingly accepted as the surgical approach of choice for most presentations of the disease and has also been proposed in the treatment of generalized peritonitis. There is not sufficient evidence supporting any changes in the approach to management in younger patients. Conversely, the available evidence suggests that surgery should be indicated after one attack of uncomplicated disease in immunocompromised individuals. Uncommon clinical presentations of sigmoid diverticulitis and their possible association with inflammatory bowel disease are also discussed.

Conventional and laparoscopic reversal of the Hartmann procedure: a review of literature

PURPOSE

The aim of this study was to provide a systematic overview on both laparoscopic and conventional Hartmann reversal. Furthermore, the Hartmann procedure is reevaluated in the light of new emerging alternatives.

METHODS

Medline, Ovid, EMBASE, and Cochrane database were searched for studies reporting on outcomes after Hartmann reversal.

RESULTS

Thirty-five studies were included in this review of which 30 were retrospective. A total of 6,249 patients with a mean age of 60 years underwent Hartmann reversal. Two thirds of patients were classified as American Society of Anesthesiologists (ASA) I-II. The mean reversal rate after a Hartmann procedure was 44%, and mean time interval between Hartmann procedure and Hartmann reversal was 7.5 months. The most frequent reported reasons for renouncing Hartmann reversal were high ASA classification and patients' refusal. The overall morbidity rate ranged from 3% to 50% (mean 16.3%) and mortality rate from 0% to 7.1% (mean 1%). Patients treated laparoscopically had a shorter hospital stay (6.9 vs. 10.7 days) and appeared to have lower mean morbidity rates compared to conventional surgery (12.2% vs. 20.3%).

CONCLUSION

Hartmann reversal carries a high risk on perioperative morbidity and mortality. The mean reversal rate is considerably low (44%). Laparoscopic reversal compares favorably to conventional; however, high level evidence is needed to determine whether it is superior.

Reversal of Hartmann's procedure following acute diverticulitis: is timing everything?

BACKGROUND

Patients who undergo a Hartmann's procedure may not be offered a reversal due to concerns over the morbidity of the second procedure. The aims of this study were to examine the morbidity post reversal of Hartmann's procedure.

METHODS

Patients who underwent a Hartmann's procedure for acute diverticulitis (Hinchey 3 or 4) between 1995 and 2006 were studied. Clinical factors including patient comorbidities were analysed to elucidate what preoperative factors were associated with complications following reversal of Hartmann's procedure.

RESULTS

One hundred and ten patients were included. Median age was 70 years and 56% of the cohort were male (n = 61). The mortality and morbidity rate for the acute presentation was 7.3% (n = 8) and 34% (n = 37) respectively. Seventy six patients (69%) underwent a reversal at a median of 7 months (range 3-22 months) post-Hartmann's procedure. The complication rate in the reversal group was 25% (n = 18). A history of current smoking (p = 0.004), increasing time to reversal (p = 0.04) and low preoperative albumin (p = 0.003) were all associated with complications following reversal.

CONCLUSIONS

Reversal of Hartmann's procedure can be offered to appropriately selected patients though with a significant (25%) morbidity rate. The identification of potential modifiable factors such as current smoking, prolonged time to reversal and low preoperative albumin may allow optimisation of such patients preoperatively.

Laparoscopically assisted reversal of Hartmann procedure

INTRODUCTION

Restoration of intestinal continuity following Hartmann procedure is an operation associated with a lengthy stay in hospital, protracted convalescence, and a high morbidity rate. With the aim of using the advantages of minimally invasive surgery, such as rapid mobilization, less postoperative pain, early restoration of bowel function, and a rapid return to a normal diet, and reduced morbidity, the laparoscopic modality was employed. The objective of the present study was to investigate the usefulness of laparoscopic restoration of intestinal continuity following Hartmann procedure.

METHOD

A total of 71 patients who, in the period between 1995 and 2005 within the framework of the prospective multicenter study "Laparoscopic Colorectal Surgery Study Group," underwent a laparoscopically assisted restoration of bowel continuity following Hartmann procedure, were investigated.

RESULTS

In 62 patients (87%), the laparoscopic procedure was completed as planned, whereas 9 cases had to be converted to open surgery-mostly on account of massive intra-abdominal adhesions. The 39 male (55%) and 32 female (45%) patients had an average body mass index of 25 (range, 19 to 38), a height of 168 cm (range, 150 to 190 cm), and a weight of 72 kg (range, 49 to 103 kg). Mean operating time was 164 min (range, 60 to 410 min) and the intraoperative blood loss 196 mL (range, 10 to 1000 mL). Five patients (7%) received packed red cells. In all, 85.9% of the procedures (n=61) were free of complications. The most common intraoperative complications were injuries to the bowel and problems with the anastomosis (dehiscence, difficult stapling), each occurring in 5.6% of the cases (n=4). Intraoperative lesions to the ureters (0%), the bladder (n=1/1.4%), and blood vessels (n=1/1.4%) played a numerically subordinate role. Purely parenteral nutrition was applied up to the third postoperative day (range, 0 to seventh postoperative day). In those patients who were able to take a liquid meal on the third postoperative day (range, first to eighth postoperative day), enteral nutrition was initiated on the fifth postoperative day (range, second to tenth postoperative day). On average, bowel movements were restored on the fourth postoperative day (range, second to ninth postoperative day). Patients in whom a bladder catheter was placed for the operation had it removed on the third postoperative day (range, first to twelfth postoperative day) and had normal urination thereafter. In Hartmann procedure, patients without such a catheter, normal urination was possible from postoperative day 1 onward (range, 0 to second postoperative day). Postoperative complications included hematomas/abscesses (n=3/4.2%), transit disorders (n=2/2.8%), surgery-requiring ileus (n=2/2.8%), cardiopulmonary complications (n=1/1.4%), and surgery-requiring hemorrhage (n=1/1.4%), with other complications accounting for 4.2% (n=3). The median hospital stay was 11 days (range, 5 to 35 d); the mortality rate was 1.4% (n=1).

CONCLUSIONS

Reversal of Hartmann procedure employing the laparoscopic modality is compatible with acceptable morbidity and mortality rates. The elevated conversion rate is a reflection of the fact that the operation is technically demanding.

Surgical practices for malignant left colonic obstruction in Germany

AIM

Data from the multicentric observation study Kolon/Rektum-Karzinome (Primärtumor) (primary colorectal carcinoma) are adduced to assess the status of surgical treatment of this condition in Germany and to compare different operative approaches in the emergency treatment of obstructive left-sided colon cancer, especially diversion (Hartmann's procedure) and primary anastomosis.

PATIENTS AND METHODS

Out of 15,911 patients with cancer of the left colon, recorded between 01.01.2000 and 31.12.2004, a total of 743 patients underwent emergency surgery for an obstructive tumour, performed as a radical resection. These patients were compared in respect of their risk profile and postoperative result.

RESULTS

In 57.9% (n=430) a one-stage operation (Group I), in 11.7% (n=87) a primary anastomosis with protective stoma (Group II), and in 30.4% (n=226), Hartmann's procedure (Group III) was performed. In Group III more patients were male, overweight and multimorbid, and more had advanced-stage tumours. The morbidity and hospital mortality (overall hospital mortality, 7.7%; n=57) did not differ significantly between the groups. The insertion of a protective stoma did not affect the rate of anastomotic insufficiency (Group I, 7%; Group II, 8.0%).

CONCLUSIONS

Primary anastomosis for emergency left colon carcinoma obstruction should only be regarded as indicated in cases where the risk profile is favourable. Our results suggest that in advanced obstruction and in high-risk cases Hartmann's procedure should be used. A protective stoma did not appear to confer any advantage.

Nonreversal of Hartmann's procedure for diverticulitis: derivation of a scoring system to predict nonreversal

PURPOSE

A Hartmann's procedure is performed in perforated diverticulitis, but in some patients the colostomy is never closed. Identification of patients at risk for Hartmann's nonreversal would be helpful to determine the extent of resection. The aim of this study was to quantify the risk of nonclosure by deriving a predictive score.

METHODS

Patients undergoing a Hartmann's procedure for diverticulitis were identified from database. They were separated into those who underwent Hartmann's reversal within one year of the initial operation, and those who did not. The data were analyzed in univariable and multivariable logistic regression. A predictive scoring system of Hartmann's reversal was created. The predictive power of the multivariable models, the predictive scoring system, and colorectal POSSUM physiology scores were compared.

RESULTS

Eighty of 117 patients (68.4%) had their colostomy reversed. Multivariate analysis identified age, American Society of Anesthesiologists' score, pulmonary comorbidity, preoperative blood transfusion, perforation, and anticoagulants as the factors of failure for stoma reversal. All 36 patients with a predictive score of less than 14 had their stoma reversed. Twenty-two of 25 patients (88%) with scores greater than 18 did not have a reversal. Predictive power was similar when using only colorectal POSSUM physiology scores alone, or with preoperative data.

CONCLUSIONS

More than 30% of patients undergoing a Hartmann's procedure for diverticulitis will not have their stoma reversed within a year. If this scoring system can be validated in an independent group of patients, it will be useful in allowing surgeons to strategize accurately and to counsel patients realistically.
