Mortality and complications following surgery for diverticulitis: Systematic review and meta-analysis

BACKGROUND

The surgical treatment of diverticulitis is in a state of evolution. Clinicians across many disciplines need to counsel patients regarding surgical choices.

OBJECTIVES

A systematic review and meta-analysis was conducted to determine the mortality and complication rates following surgery for diverticulitis in both the emergent and elective setting.

METHODS

We searched PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) for relevant articles published from 1980 to 2012. The primary outcome of interest was the point estimate of mortality, following surgery for diverticulitis.

RESULTS

Of the 289 citations reviewed, we included 59 studies. Overall, the point estimate for mortality was 3.05%, with a 95% confidence intereval (CI) of 1.73-5.32 and p < 0.001. Mortality following emergent surgery was 10.64% (95% CI 7.95-14.11; p < 0.001), versus 0.50% (95% CI 0.46-0.54; p < 0.001) following elective operations. A laparoscopic approach had an estimated mortality of 0.75% (95% CI 0.35-1.58; p < 0.001), compared to an open surgical approach, which had a mortality of 4.69% (95% CI 2.29-9.36, p < 0.001). The mortality following a resection with primary anastomosis was 1.96% (95% CI 1.22-3.13; p < 0.001) and for the Hartmann's procedure was 14.18% (95% CI 9.83-20.03; p < 0.001). A comparative analysis found that the risk of post-operative mortality was significantly higher following emergent surgery, compared to elective surgery (odds ratio (OR): 6.12 with 95% CI 1.62-23.10; p = 0.008; Q = 2.56, p = 0.46 and I2 = 0); the open approach, compared to a laparoscopic approach (OR: 36.43 with 95% CI 9.94-133.6; p = 0.13; and Q = 2.79, p = 0.25 and I2 = 28.26); and for Hartmann's procedure, compared to primary anastomosis without diversion (OR: 25.45 with 95% CI 15.13-42.81, p < 0.001; and Q = 23.34, p = 0.14 and I2 = 27.16). The overall reported post-operative complication rate was 32.64% (95% CI 27.43-38.32; p < 0.00). The overall surgical and medical complication rates were 18.96% and 13.93%, respectively.

CONCLUSIONS

Urgent surgical treatment of diverticulitis has a significant complication rate. Even elective surgery has a significant complication rate that needs to be considered when doing the clinical decision-making for recurrent diverticulitis.

Management of malignant left colonic obstruction: is an initial temporary colostomy followed by surgical resection a better option?

AIM

The surgical management of obstructed left colorectal cancer (OLCC) is still a matter of debate, and current guidelines recommend Hartmann's procedure (HP). The study evaluated the results of the surgical management with a focus on a strategy of initial colostomy (IC) followed by elective resection.

METHOD

All patients operated on for OLCC were reviewed. Clinical, surgical, histological, morbidity and long-term results were noted.

RESULTS

From 2000-11, 83 patients (48 men) with a mean age of 70.3 ± 15.1 years underwent surgery for OLCC. Eleven (13.3%) had a subtotal colectomy owing to a laceration of the caecal wall. Eleven had a HP for tumour perforation (n = 6) or as palliation in a severely ill patient (n = 5). The remaining 61 (73.5%) patients had an IC, with the intention of performing an elective resection shortly after recovery. Postoperative complications occurred in six (9.8%) and there were two (3.3%) deaths. Fifty-nine operation survivors had a colonoscopy shortly afterwards which showed a synchronous cancer in two (3.4%). Twelve of the 59 patients had synchronous metastases. The subsequent elective resection including the colostomy site could be performed in 45 (74%) patients during the same admission at a median interval of 11 (7-17) days. The overall median length of hospital stay was 20 days and the 30-day mortality was 3/61 (5%).

CONCLUSION

IC followed by surgical resection is a technically simple strategy, allowing initial abdominal exploration with a short period of having a colostomy, and permitting elective surgery with a low morbidity and full oncological lymphadenectomy.

Laparoscopic Lavage in the Management of Perforated Diverticulitis: a Contemporary Meta-analysis

IMPORTANCE

Perforated diverticulitis carries the risk of significant comorbidity and mortality. Although colon resection provides adequate source control, the procedure itself carries morbidity, as well as later stoma reversal procedures. The effectiveness of laparoscopic lavage to treat perforated diverticulitis remains unclear.

OBJECTIVE

We aimed to conduct a meta-analysis to evaluate current studies comparing laparoscopic lavage with colon resection in cases of perforated diverticulitis for the effectiveness in source control, without the need for subsequent interventions, stoma formation, and death.

DATA SOURCES

Electronic database searches were conducted using EMBASE, Pubmed, CINAHL, Cochrane databases, and clinicaltrials.gov following PRISMA guidelines.

STUDY SELECTION

Randomized controlled trials (RCTs) were included that compared laparoscopic lavage against colon resection for perforated diverticulitis.

DATA EXTRACTION AND SYNTHESIS

Risk of bias in RCT's was assessed the Cochrane Assessment of Bias risk tool and Jadad scale. A meta-analysis was performed using random-effects risk ratios (RR) and 95% confidence intervals (CI).

MAIN OUTCOME

Outcome measures included the total rate of reoperation, rate of reoperation for infection, need for subsequent percutaneous drainage, stoma formation, and mortality rate within 90 days.

RESULTS

Three eligible randomized controlled studies were identified, with a combined total of 372 patients. Laparoscopic lavage carried an increased rate of total reoperations (RR 2.07; CI 1.12-3.84; p = 0.021) and an increased rate of reoperation for infection (RR 5.56; CI 1.97-15.69; p = 0.001) compared with colon resection. In addition, laparoscopic lavage increased the rate of subsequent percutaneous drainage (RR 6.54; CI 1.77-24.16; p = 0.005) compared with colon resection, but a lesser risk of stoma formation within 90 days (RR 0.18; CI 0.12-0.27; p < 0.001). No difference in mortality rate was observed between treatments (RR 1.03; CI 0.45-2.34; p = 0.950).

CONCLUSION

Despite decreased rates of stoma formation and equivalent mortality rates as compared with colon resection, laparoscopic lavage for Hinchey III diverticulitis fails to completely control the source of infection. Our data show that laparoscopic lavage is associated with increased rates of total reoperations, increased rates of reoperation for infections, and need for subsequent percutaneous drainage.

Meta-analysis of surgical strategies in perforated left colonic diverticulitis with generalized peritonitis

PURPOSE

Surgical strategies for perforated diverticulitis (Hinchey stages III and IV) remain controversial. This systematic review aimed to compare the outcome of primary anastomosis, Hartmann procedure and laparoscopic lavage.

METHODS

A systematic literature search was conducted through Medline, Embase, Cochrane Central Register and Health Technology Assessment Database to identify randomized and non-randomized controlled trials involving patients with perforated left-sided colonic diverticulitis comparing different surgical strategies. The methodological quality of the included studies was assessed systematically (Grading of Recommendations, Assessment, Development and Evaluation) and a meta-analysis was performed.

RESULTS

After screening 4090 titles and abstracts published between 1958 and January 2018, 148 were selected for full text assessment. Sixteen trials (7 RCTs, 9 non-RCTs) with 1223 patients were included. Mortality rates were not significantly different between Hartmann procedure and primary anastomosis for Hinchey III and IV, neither in the meta-analysis of three RCTs (RR 2.03 (95% CI 0.79 to 5.25); p = 0.14, moderate quality of evidence) nor in the meta-analysis of six observational studies (RR 1.53 (95% CI 0.89 to 2.65); p = 0.13, very low quality of evidence). However, stoma reversal rates were significantly higher in the primary anastomosis group (RR 0.73 (95% CI 0.58 to 0.98); p = 0.008, moderate quality of evidence). Meta-analysis of four RCTs showed no significant difference between laparoscopic lavage for Hinchey III compared to sigmoid resection neither for mortality (RR 1.07 (95% CI 0.65 to 1.76); p = 0.79, moderate quality of evidence) nor for major complications (RR 0.86 (95% CI 0.69 to 1.08); p = 0.20, moderate quality of evidence).

CONCLUSIONS

This systematic review suggests similar rates of complications but higher rates of colonic restoration after primary anastomosis compared to Hartmann procedure in perforated diverticulitis with generalized peritonitis (Hinchey III and IV). Results in laparoscopic lavage for Hinchey III are not superior to primary resection. However, further studies with a careful interpretation of the meaning of re-interventions are required.

Relationship between stoma creation route for end colostomy and parastomal hernia development after laparoscopic surgery

BACKGROUND

The therapeutic benefits of extraperitoneal colostomy with laparoscopic surgery remain unclear. The aim of this study was to investigate the relationship between the route for stoma creation with laparoscopic surgery and stoma-related complications, especially parastomal hernia (PSH).

METHODS

From January 2007 to March 2015, a total of 59 patients who underwent laparoscopic abdominoperineal resection or Hartmann procedure were investigated. Patient demographic and treatment characteristics, including stoma-related complications, were analyzed retrospectively.

RESULTS

Transperitoneal and extraperitoneal colostomy were performed in 29 and 30 patients, respectively. Median follow-up duration was 21 months (range: 2-95). Patient demographic and treatment characteristics were comparable between the transperitoneal group (TPG) and the extraperitoneal group (EPG). PSH developed in 12 (41 %) patients in TPG, and 4 (13 %) patients in EPG (p = 0.020). The incidence of other stoma-related complications and non-stoma-related complications did not differ significantly between TPG and EPG. No patient characteristics except for transperitoneal route for stoma creation were associated with PSH development.

CONCLUSIONS

The extraperitoneal route for stoma creation is associated with a significantly lower incidence of PSH development after laparoscopic surgery. Whenever possible, extraperitoneal colostomy should be recommended, even with laparoscopic surgery.

Primary anastomosis and nonrestorative resection for perforated diverticulitis with peritonitis: meta-analysis of randomized trials

AIM

The aim of this meta-analysis was to comparatively evaluate the outcomes of primary anastomosis (PRA) and nonrestorative resection (NRR) as emergency surgery and ostomy reversal in patients with perforated diverticulitis and peritonitis.

METHODS

PubMed, MEDLINE via Ovid, Embase, CINAHL, Cochrane Library and Web of Science databases were systematically searched. Postoperative morbidity following emergency resection was the primary end-point. Quality assessment of the included studies was performed using the Cochrane Quality Assessment Tool including recruitment bias and crossover with intention-to-treat analysis. The Haenszel-Mantel method with odds ratios (OR, 95% CI) and the inverse variance method with mean difference (MD, 95% CI) as effect measures were utilized for dichotomous and continuous outcomes, respectively.

RESULTS

Four randomized controlled trials totaling 382 patients (180 PRA vs 204 NRR) were included. Morbidity rates following emergency resection did not differ (OR = 0.99, 95% CI 0.65, 1.51; P = 0.95; number needed to treat/harm (NNT) 96). Organ/space surgical site infection rates were 3.3% in PRA vs 11.3% in NRR (OR = 0.29, 95% CI 0.12, 0.74; P = 0.009; NNT = 13). Postoperative morbidity rates following ostomy reversal were significantly lower in PRA (OR = 0.31, 95% CI 0.15, 0.64; P = 0.001; NNT = 7). Pooled ostomy non-reversal rates were 16% in PRA vs 35.5% in NRR (OR = 0.37, 95% CI 0.22, 0.62; P = 0.0001; NNT = 6) with high heterogeneity (I²  = 63%; τ²  = 8.17). Meta-regression analysis revealed significant negative correlation between the PRA-to-NRR crossover rate and the ostomy non-reversal rate (P = 0.029).

CONCLUSION

This meta-analysis found that PRA was associated with better short- and long-term outcomes at the cost of significantly longer operating time at emergency surgery.

Single-port laparoscopic surgery for sigmoid volvulus

AIM: To report our experience with single-port laparoscopic surgery (SPLS) for sigmoid volvulus (SV).

METHODS: Between October 2009 and April 2013, 10 patients underwent SPLS for SV. SPLS was performed transumbilically or through a predetermined stoma site. Conventional straight and rigid-type laparoscopic instruments were used. After intracorporeal, segmental resection of the affected sigmoid colon, the specimen was extracted through the single-incision site. Patient demographics and perioperative data were analyzed.

RESULTS: SPLS for SV was successful in all 10 patients (4, resection and primary anastomosis; 6, Hartmann’s procedure). The median operative time and postoperative hospitalization period were 168 (range, 85-315) min and 6.5 (range, 4-29) d, respectively. No intraoperative complications were noted; there were 2 postoperative complications, including 1 anastomotic leak.

CONCLUSION: SPLS was a safe and feasible therapeutic approach for SV, when performed by a surgeon experienced in conventional laparoscopic surgery.

Damage control strategy in perforated diverticulitis with generalized peritonitis

Background

The best treatment for perforated colonic diverticulitis with generalized peritonitis is still under debate. Concurrent strategies are resection with primary anastomosis (PRA) with or without diverting ileostomy (DI), Hartmann’s procedure (HP), laparoscopic lavage (LL) and damage control surgery (DCS). This review intends to systematically analyze the current literature on DCS.

Methods

DCS consists of two stages. Emergency surgery: limited resection of the diseased colon, oral and aboral closure, lavage, vacuum-assisted abdominal closure. Second look surgery after 24–48 h: definite reconstruction with colorectal anastomosis (−/ + DI) or HP after adequate resuscitation. The review was conducted in accordance to the PRISMA-P Statement. PubMed/MEDLINE, Cochrane central register of controlled trials (CENTRAL) and EMBASE were searched using the following term: (Damage control surgery) AND (Diverticulitis OR Diverticulum OR Peritonitis).

Results

Eight retrospective studies including 256 patients met the inclusion criteria. No randomized trial was available. 67% of the included patients had purulent, 30% feculent peritonitis. In 3% Hinchey stage II diverticulitis was found. In 49% the Mannheim peritonitis index (MPI) was greater than 26. Colorectal anastomosis was constructed during the course of the second surgery in 73%. In 15% of the latter DI was applied. The remaining 27% received HP. Postoperative mortality was 9%, morbidity 31% respectively. The anastomotic leak rate was 13%. 55% of patients were discharged without a stoma.

Conclusion

DCS is a safe technique for the treatment of acute perforated diverticulitis with generalized peritonitis, allowing a high rate of colorectal anastomosis and stoma-free hospital discharge in more than half of the patients.

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.

Laparoscopic reversal of Hartmann procedure

Background:

The Hartmann procedure is a standard life-saving operation for acute left colonic complications. It is usually performed as a temporary procedure with the intent to reverse it later on. This reversal is associated with considerable morbidity and mortality by open method. The laparoscopic reestablishment of intestinal continuity after Hartmann procedure has shown better results in terms of decrease in morbidity and mortality.

Materials and Methods:

The laparoscopic technique was used consecutively in 12 patients for the reversal of Hartmann procedure in the last 3 years. The adhesiolysis and mobilization of the colon was done under laparoscopic guidance. The colostomy was mobilized and returned to abdominal cavity after tying the anvil in the proximal end. An end-to-end intracorporeal anastomosis was performed between the proximal colon and the rectum using the circular stapler.

Results:

Mean age of the patients was 40 years and the mean time of restoration of intestinal continuity was 130 days. Two patients were converted to open. The mean time of operation was 90 min. There were no postoperative complications and mortality. The mean hospital stay was 5 days.

Conclusion:

Laparoscopic reversal of Hartmann is technically safe and feasible.

Standardization of laparoscopic reversal of the Hartmann procedure: A single-center report

INTRODUCTION

Reestablishing continuity after the Hartmann procedure, the Hartmann reversal has been recognized as a complex procedure with a high morbidity rate. Laparoscopic reversal of the Hartmann procedure (LHR) is technically challenging, although good short-term results have been reported. We formulated this technique in 2013 and have been gradually devising and standardizing it.

MATERIAL AND SURGICAL TECHNIQUE

Ten patients who had undergone the Hartmann procedure from January 2013 to December 2019 and subsequently LHR were retrospectively examined. During the procedure, a circular incision was made at the original site of the colostomy to safely reach the abdominal cavity, and pneumoperitoneum was performed using the glove technique. Next, pelvic adhesions and the descending colon were dissected. If the rectal stump was difficult to identify, an intraoperative endoscope was used. Finally, either a Gambee or stapled anastomosis without tension was performed. The median surgical time was 265 minutes (range, 160-435 minutes), and the median blood loss was 100 mL (range, 10-700 mL). The median postoperative hospital stay was 11 days (range, 8-14 days). In one case, laparotomy was performed because of severe intra-abdominal adhesion.

DISCUSSION

No major complication was observed during or after surgery. Therefore, LHR can be performed safely. Standardizing this procedure could render it minimally invasive, although a high level of evidence is needed.

Using new technicque in sigmoid volvulus surgery in patients affected by COVID19

INTRODUCTION

Coronavirus pandemic-initiated Wuhan city, Hubei Province, China. It mainly involves respiratory system and cause fever, cough. However, it has other manifestations such as GI system, CNS and skin involvement. It is transmitted mostly through respiratory system, but some researchers claim that in can potentially spread by oral, fecal or intestinal gas. During colorectal surgeries such as volvulus sigmoid, surgeons are at risk of exposure to intestinal gas.

CASE PRESENTATION

A 57-year-old mentally retarded man came to our emergency department with complain of abdominal pain, constipation, obstipation, nausea, vomiting and abdominal distention. His vital sign was stable and his laboratory data revealed no abnormality. His abdominal x-ray showed intestinal obstruction with suspicious of sigmoid volvulus. His PCR for COVID 19 was positive and his chest CT scan has manifestations of lung involvement. He was proceeded for surgery.

CONCLUSION

Owing to odds of spread of coronavirus through intestinal gas, in this case, sigmoid colon was removed without evacuation of intestinal gas.

Complicated diverticular disease: Position statement on outpatient management, Hartmann's procedure, laparoscopic peritoneal lavage and laparoscopic approach. Consensus document of the Spanish Association of Coloproctology and the Coloproctology Section of the Spanish Association of Surgeons

The Spanish Association of Coloproctology (AECP) and the Coloproctology Section of the Spanish Association of Surgeons (AEC), propose this consensus document about complicated diverticular disease that could be used for decision-making. Outpatient management, Hartmann's procedure, laparoscopic peritoneal lavage, and the role of a laparoscopic approach in colonic resection are exposed.

An outcome analysis of laparoscopic management of diverticulitis

BACKGROUND

All operative procedures for simple or complicated diverticulitis, including primary resection and anastomosis (PRA) with or without a diverting stoma, Hartmann procedure (HP), or stoma reversal, whether done in an elective setting or as an emergency, can be performed laparoscopically. However, owing to low incidence of the disease and complexity of the procedure, there are very few studies on outcomes of laparoscopic surgery for sigmoid diverticulitis from India.

AIM

The present study was undertaken to evaluate outcomes of laparoscopically treated patients of sigmoid diverticulitis.

METHODS

Prospective observational study enrolled 37 patients with sigmoid diverticulitis managed laparoscopically from March 2015 to March 2017. Demographic, clinical, operative, postoperative, and complication data were entered into a patient proforma and analyzed.

RESULTS

Eleven simple and 26 complicated diverticulitis patients were operated laparoscopically, 22 in emergency setting and 15 in elective setting. Only three patients required conversion to open surgery-two due to dense adhesions and one due to chronic obstructive pulmonary disease (COPD). No patients had ureteric or bowel injury. Eighteen patients underwent laparoscopic PRA without stoma, 11 patients had PRA with stoma, 6 had HP, and 2 had laparoscopic lavage. Results showed lesser blood loss, shorter hospital stay, and fewer complications in the elective group and simple diverticulitis patients. None of the patients had anastomosis-related complications. Two patients had stoma-related complications.

CONCLUSION

Laparoscopic management of diverticulitis is feasible, safe, provides the benefits of less wound-related complications, and shorter hospital stay and should be the surgical procedure of choice in elective or emergency setting for simple/complicated diverticulitis.

Surgical results of Hartmann procedure in emergency cases with left-sided colorectal cancer

OBJECTIVE

We aimed to define indication of Hartmann procedure (HP) under emergency conditions, analyze, and present in which cases this procedure should be used.

METHODS

The patients who underwent emergency surgery for colorectal cancer were analyzed. Rates of mortality, overall, and disease-free survival of the patients were evaluated. The colostomy closure rate, operative mortality, and surgical complications of the secondary operation performed after the HP were also assessed.

RESULTS

Fifty-seven patients who underwent HP were included in the study. The indications were obstruction (n = 37) or perforation (n = 20). The post-operative mortality and morbidity rates were 21.1% and 63.2%, respectively. The 1-, 3-, and 5-year survival rates for all patients were 54%, 49%, and 45%.

CONCLUSION

HP can be a life-saving procedure in cases of high risk, emergency colorectal disease. Surgeons create a temporary stoma as a part of this procedure that is generally closed with a second operation. However, it is not possible to close the stoma in some cases, and the potential physical and emotional issues related to the stoma should be a part of the surgeon's considerations.

Laparoscopic Hartmann Reversal: Experiences From a Developing Country

Purpose

Laparoscopic surgery is considered a promising approach for Hartmann reversal but is also a complicated major surgical procedure. We conducted a retrospective analysis at a city hospital in Vietnam to evaluate the treatment technique and outcomes of laparoscopic Hartmann reversal (LHR).

Methods

A colorectal surgery database in 5 years between 2015 and 2019 (1,175 cases in total) was retrieved to collect 35 consecutive patients undergoing LHR.

Results

The patients had a median age of 61 years old. The median operative time was 185 minutes. All the procedures were first attempted laparoscopically with a conversion rate of 20.0% (7 of 35 cases). There was no intraoperative complication. Postoperative mortality and morbidity were 0 and 11.4% (2 medical, 1 deep surgical site infection, and 1 anastomotic leak required reoperation) respectively. The median time to first bowel activity was 2.8 days and median length of hospital stay was 8 days.

Conclusion

When performed by skilled surgeons, LHR is a feasible and safe operation with acceptable morbidity rate.

Contemporary management of diverticulitis

The treatment of diverticulitis is experiencing a shift in management due to a number of large scale clinical trials. For instance, clinicians are beginning to recognize that avoidance of antibiotics in uncomplicated diverticulitis is not associated with worse outcomes. Additionally, while the decision to proceed with elective surgical resection for recurrent uncomplicated disease is less conclusive and favors a patient-centric approach, complicated disease with a large abscess denotes more aggressive disease and would likely benefit from elective surgical resection. Lastly, in patient with acutely perforated diverticulitis who require urgent surgical intervention, laparoscopic lavage is generally not recommended due to high re-intervention rates and the preferred surgical procedure is primary anastomosis with or without diversion due to high morbidity and low rates of Hartmann reversal.

Primary anastomosis with diverting loop ileostomy vs. Hartmann's procedure for acute diverticulitis: what happens after discharge? Results of a nationwide analysis

BACKGROUND

Current guidelines recommend resection with primary anastomosis with diverting loop ileostomy over Hartmann's procedure if deemed safe for acute diverticulitis. The primary objective of the current study was to compare the utilization of these strategies and describe nationwide ostomy closure patterns and readmission outcomes within 1 year of discharge.

METHODS

This was a retrospective, population-based, cohort study of United States Hospitals reporting to the Nationwide Readmissions Database from January 2011 to December 2019. There were 35,774 patients identified undergoing non-elective primary anastomosis with diverting loop ileostomy or Hartmann's procedure for acute diverticulitis. Rates of ostomy closure, unplanned readmissions, and complications were compared. Cox proportional hazards and logistic regression models were used to control for patient and hospital-level confounders as well as severity of disease.

RESULTS

Of the 35,774 patients identified, 93.5% underwent Hartmann's procedure. Half (47.2%) were aged 46-65 years, 50.8% female, 41.2% publicly insured, and 91.7% underwent open surgery. Primary anastomosis was associated with higher rates of 1-year ostomy closure (83.6% vs. 53.4%, p < 0.001) and shorter time-to-closure [median 72 days (Interquartile range 49-103) vs. 115 (86-160); p < 0.001]. Primary anastomosis was associated with increased unplanned readmissions [Hazard Ratio = 2.83 (95% Confidence Interval 2.83-3.37); p < 0.001], but fewer complications upon stoma closure [Odds Ratio 0.51 (95% 0.42-0.63); p < 0.001]. There were no differences in complications between primary anastomosis and Hartmann's procedure during index admission [Odds Ratio = 1.13 (95% Confidence Interval 0.96-1.33); p = 0.137].

CONCLUSION

Patients who undergo primary anastomosis for acute diverticulitis are more likely to undergo ostomy reversal and experience fewer postoperative complications upon stoma reversal. These data support the current national guidelines that recommend primary anastomosis in appropriate cases of acute diverticulitis requiring operative treatment.

Safety of early Hartmann reversal during adjuvant chemotherapy in colorectal cancer: a pilot study

Introduction

Most patients undergoing the Hartmann procedure for complicated colorectal cancer require chemotherapy because of their advanced status. Stoma created during the procedure is typically closed after the completion of postoperative chemotherapy. However, stomas can induce medical or surgical complications and disturb quality of life. This study aimed to evaluate the safety of Hartmann's reversal during postoperative chemotherapy.

Methods

We conducted a retrospective review of electronic medical records. Between 2017 and 2021, 96 patients underwent Hartmann reversal for after colorectal cancer surgery. Among them, the number of patients who underwent Hartmann procedure with radical resection of complicated colorectal cancer and Hartmann reversal during adjuvant chemotherapy was 13. The clinical, surgical, and pathological characteristics of the patients were evaluated.

Results

Eight and five patients had obstructions and perforations, respectively. Two patients with synchronous liver metastases underwent simultaneous liver resection and reversal simultaneously. Five and eight patients received adjuvant chemotherapy with capecitabine and FOLFOX, respectively. The median interval between the Hartmann procedure and reversal was 3.31 months (2.69-5.59). The median operative time for Hartmann's reversal was 190 min (100-335). The median hospital stay was 10 days (7-21). Four patients (30.8%) developed postoperative complications, and the rate of 3 or higher grade according to the Clavien-Dindo classification within 90 days postoperatively was 0%. Except for 1 patient who refused continuation of chemotherapy, 12 patients completed the planned chemotherapy. Median total duration of adjuvant chemotherapy was 6.78 months (5.98-8.48). There was no mortality.

Conclusion

Early Hartmann reversal during adjuvant chemotherapy is tolerable and safe in carefully selected patients. In particular, it can be used as a therapeutic option for patients with complicated colorectal cancer with synchronous resectable metastases.

Catastrophic outcome following misidentification of bowel anatomy during Hartmann's reversal: A case report and technical considerations

BACKGROUND

Reversal of Hartmann's procedure is a complex surgery with potential complications. This case report describes a rare and severe complication following an attempted reversal.

CASE PRESENTATION

A 53-year-old male who had undergone a Hartmann's procedure for non-metastatic sigmoid colon cancer presented with bowel obstruction 10 days after attempted reversal surgery at another hospital. Imaging studies suggested an entero-colic fistula. Emergency laparotomy revealed dense adhesions and multiple bowel injuries. The procedure was terminated, and controlled fistulae were created.

MANAGEMENT AND OUTCOME

The patient required two months of intensive care. A subsequent surgery excised the fistulae and restored intestinal continuity, leaving the patient with an end colostomy and approximately 120 cm of ileum.

CONCLUSION

This case highlights the potential risks of Hartmann's reversal and emphasizes the importance of proper patient selection, timing, and surgical expertise. It underscores the need for thorough preoperative evaluation and preparation when attempting such complex surgeries.

Bowel Preparation for Elective Hartmann Operation: Analysis of the National Surgical Quality Improvement Program Database

Background: Use of pre-operative bowel preparation in colorectal resection has not been examined solely in patients who have had colorectal resection with primary colostomy (Hartmann procedure). We aimed to evaluate the association of bowel preparations with short-term outcomes after non-emergent Hartmann procedure. Patients and Methods: The National Surgical Quality Improvement Program Participant Use File colectomy database was queried for patients who had elective open or laparoscopic Hartmann operation. Patients were grouped by pre-operative bowel preparation: no bowel preparation, oral antibiotic agents, mechanical preparation, or both mechanical and oral antibiotic agent preparation (combined). Propensity analysis was performed, and outcomes were compared by type of pre-operative bowel preparation. The primary outcome was rate of any surgical site infection (SSI). Secondary outcomes included overall complication, re-operation, re-admission, Clostridioides difficile colitis, and length of stay. Results: Of the 4,331 records analyzed, 2,040 (47.1%) patients received no preparation, 251 (4.4%) received oral antibiotic preparation, 1,035 (23.9%) received mechanical bowel preparation, and 1,005 (23.2%) received combined oral antibiotic and mechanical bowel preparation. After propensity adjustment, rates of any SSI, overall complication, and length of hospital stay varied significantly between pre-operative bowel regimens (p < 0.005). The use of combined bowel preparation was associated with decreased rate of SSI, overall complication, and length of stay. No difference in rate of re-operation or post-operative Clostridioides difficile infection was observed based on bowel preparation. Conclusions: Compared with no pre-operative bowel preparation, any bowel preparation was associated with reduced rate of SSI, but not rate of re-operation or post-operative Clostridioides difficile infection.
