Factors influencing the morbidity of colostomy closure

Proximal protective diverting ostomy following colon anastomosis for penetrating trauma may not be protective: A matched cohort study

INTRODUCTION

Despite the shift toward liberal primary anastomosis in penetrating colon injuries, some surgeons recommend a protective diverting ostomy (DO) proximal to the anastomosis. This study evaluates the effect of DO on outcomes in patients undergoing colon resection and anastomosis following penetrating trauma.

METHODS

The TQIP database (2013-2018) was queried for penetrating colon injuries undergoing colectomy and anastomosis. Patients receiving DO were propensity matched to patients without diverting ostomy (woDO) (1:3). Outcomes were compared between groups.

RESULTS

After matching, 89 DO patients were analyzed. The DO group had more surgical site infections (32 ​% vs. 21 ​%; p ​< ​0.05) and longer hospital stay (20 [13-27] vs. 15 [9-25]; p ​< ​0.05) compared to the woDO group. Mortality and unplanned operations were similar between groups.

CONCLUSIONS

Diverting ostomy after colon resection and anastomosis is associated with increased infectious complications without decreasing unplanned operations or mortality. Its routine role in penetrating colon trauma needs reassessment.

PHaLIR: prevent hernia after loop ileostomy reversal-a study protocol for a randomized controlled multicenter study

BACKGROUND

Rectal cancer is a common cancer worldwide. Surgery for rectal cancer with low anterior resection often includes the formation of a temporary protective loop ileostomy. The temporary ostomy is later reversed in a separate operation. One complication following stoma closure is the development of a hernia at the former stoma site, and this has been reported in 7-15% of patients. The best method to avoid hernia after stoma closure is unclear. The most common closure is by suturing only, but different forms of mesh have been tried. Biological mesh has in a randomized trial halved hernia incidence after stoma reversal. Biosynthetic mesh and retromuscular mesh are currently being evaluated in ongoing studies.

METHODS

The present multicenter, double-blinded, randomized, controlled study will compare standard suture closure of the abdominal wall in loop ileostomy reversal with retromuscular synthetic mesh at the stoma site. The study has been approved by the Regional Ethical Review board in Stockholm. Patients aged 18-90 years, operated on with low anterior resection and a protective loop ileostomy for rectal cancer and planned for ileostomy reversal, will be considered for inclusion in the study. Randomization will be 1:1 on the operation day with concealed envelopes. The estimated sample size is intended to evaluate the superiority of the experimental arm and to detect a reduction of hernia occurrence from 12 to 3%. The operation method is blinded to the patients and in the chart and for the observer at the 30-day follow-up. The main outcome is hernia occurrence at the stoma site within 3 years postoperatively, diagnosed through CT with strain. Secondary outcomes are operation time, length of hospital stay, pain, and 30-day complications.

DISCUSSION

This double-blinded randomized controlled superiority study will compare retromuscular synthetic mesh during the closure of loop ileostomy to standard care. If this study can show a lower frequency of hernia with the use of prophylactic mesh, it may lead to new surgical guidelines during stoma closure.

Study of Purse-string Skin Closure Plus Negative-pressure Wound Therapy for Stoma Closure

Background

Although purse-string skin closure (PSC) is an effective method for stoma closure considering wound infection, the period for scarring will be prolonged. The aim of this study was to assess whether negative-pressure wound therapy (NPWT) can reduce the wound-scarring period for PSC after stoma closure.

Methods

Patients who underwent stoma closure between January 2015 and August 2020 at our department were retrospectively assessed. Patients in the control group received only PSC, and patients in the NPWT group received both PSC and NPWT using the VAC® or PICO®. The primary endpoint of this study was the short-term reduction ratio (RR). The RR is calculated by the length, width, and depth of the wound of the stoma closure site. The secondary endpoints were scarring period and wound-related complications such as surgical site infection, dermatitis, bleeding, enterocutaneous fistula, and ventral hernia.

Results

Of the 53 patients included in this study, 21 had their stoma closed by PSC and 32 had their stoma closed by PSC plus NPWT. No significant differences were observed in patient characteristics or peri-operative states. The RR in the NPWT group was significantly smaller than that in the PSC group at 7 postoperative days (p=0.04). There was no difference in scarring period between the two groups (p=0.11).The rates of postoperative wound-related complications were similar in the two groups (control group: 4 (19%), NPWT group: 7 (21.9%), p=1.0).

Conclusions

Our study suggests that PSC plus NPWT might be more effective for wound healing after stoma closure than only PSC.

Destructive colon injuries requiring resection: Is colostomy ever indicated?

BACKGROUND

The management of destructive colon injuries requiring resection has shifted from mandatory diverting stoma to liberal use of primary anastomosis. Various risk criteria have been suggested for the selection of patients for primary anastomosis or ostomy. At our center, we have been practicing a policy of liberal primary anastomosis irrespective of risk factors. The purpose of this study was to evaluate the colon-related outcomes in patients managed with this policy.

METHODS

This retrospective study included all colon injuries requiring resection. Data collected included patient demographics, injury characteristics, blood transfusions, operative findings, operations performed, complications, and mortality.

RESULTS

A total of 287 colon injuries were identified, 101 of whom required resection, forming the study population. The majority (63.4%) were penetrating injuries. Furthermore, 16.8% were hypotensive on admission, 40.6% had moderate or severe fecal spillage, 35.6% received blood transfusion of >4 U, and 41.6% had Injury Severity Score of >15. At index operation, 88% were managed with primary anastomosis and 12% with colon discontinuity, and one patient had stoma. Damage-control laparotomy (DCL) with temporary abdominal closure was performed in 39.6% of patients. Of these patients with DCL, 67.5% underwent primary anastomosis, 30.0% were left with colon discontinuity, and 2.5% had stoma. Overall, after the definitive management of the colon, including those patients who were initially left in colon discontinuity, only six patients (5.9%) had a stoma. The incidence of anastomotic leaks in patients with primary anastomosis at the index operation was 8.0%, and there was no colon-related mortality. The incidence of colon anastomotic leaks in the 27 patients with DCL and primary anastomosis was 11.1%, and there was no colon-related mortality. Multivariate analysis evaluating possible risk factors identified discontinuity of the colon as independent risk factor for mortality.

CONCLUSION

Liberal primary anastomosis should be considered in almost all patients with destructive colon injuries requiring resection, irrespective of risk factors.

Article Commentary: Evolving Colon Injury Management: A Review

The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

Hernia at the stoma site after loop ileostomy reversal

PURPOSE

To estimate the incidence of and risk factors for stoma site hernia after closure of a temporary diverting ileostomy.

METHOD

In a non-comparative cohort study, charts (n = 216) and CT-scans (n = 169) from patients who had undergone loop ileostomy closure following low anterior resection for rectal cancer 2010-2015 (mainly open surgery) at three hospitals were evaluated retrospectively. Patients without hernia diagnosis were evaluated cross-sectionally through a questionnaire (n = 158), and patients with symptoms of bulging or pain were contacted and offered a clinical examination or a CT scan including Valsalva maneuver.

RESULTS

In the chart review, five (2.3%) patients had a diagnosis of incisional hernia at the previous stoma site after 8 months (median). In 12 patients, the CT scan showed a hernia, of which 8 had not been detected previously. The questionnaire was returned by 130 (82%) patients, of which 31% had symptoms of bulging or pain. Less than one in five of patients who reported bulging were diagnosed with hernia, but the absolute majority of the radiologically diagnosed hernias reported symptoms. By combining clinical and radiological diagnosis, the cumulative incidence of hernia was 7.4% during a median follow up time of 30 months. Risk factors for stoma site hernia were male sex and higher BMI.

CONCLUSION

Hernia at the previous stoma site was underdiagnosed. Less than a third of symptomatic patients had a hernia diagnosis in routine follow up. Randomized studies are needed to evaluate if prophylactic mesh can be used to prevent hernias, especially in patients with risk factors.

Laparoscopic reversal of Hartmann's procedure

Reestablishing continuity after a Hartmann's procedure is considered a major surgical procedure with high morbidity/mortality. The aim of this study was to assess the short-/long-term outcome of laparoscopic restoration of bowel continuity after HP. A prospectively collected database of colorectal laparoscopic procedures (>800) performed between June 2005 and June 2013 was used to identify 20 consecutive patients who had undergone laparoscopic reversal of Hartmann's procedure (LHR). Median age was 65.4. Ten patients (50 %) had undergone surgery for perforated diverticulitis, 3 (15 %) for cancer, and 7 (35 %) for other reasons (volvulus, posttraumatic perforation, and sigmoid perforation from foreign body). Previous HP had been performed laparoscopically in only 3 patients. Median operative time was 162.5 min. All the procedures were completed laparoscopically. Intraoperative complication rate was nil. Post-operative mortality and morbidity were respectively 0 and 10 % (1 pneumonia, 1 bowel obstruction from post-anastomotic stenosis which required resection and redo of the anastomosis). Median time to first flatus was 3 days, to normal diet 5 days. Median hospital stay was 9 days without readmissions. We followed up the patients for a median of 44 months: when asked, all 20 (100 %) said they would undergo the operation (LHR) again; 3 (15 %) had been re-operated of laparoscopic mesh repair for incisional hernia. When performed by experienced surgeons, LHR is a feasible, safe, reproducible operation, which allows early return of bowel function, early discharge and fast return to work for the patient. It has a low morbidity rate.

Position paper: management of perforated sigmoid diverticulitis

Over the last three decades, emergency surgery for perforated sigmoid diverticulitis has evolved dramatically but remains controversial. Diverticulitis is categorized as uncomplicated (amenable to outpatient treatment) versus complicated (requiring hospitalization). Patients with complicated diverticulitis undergo computerized tomography (CT) scanning and the CT findings are used categorize the severity of disease. Treatment of stage I (phlegmon with or without small abscess) and stage II (phlegmon with large abscess) diverticulitis (which includes bowel rest, intravenous antibiotics and percutaneous drainage (PCD) of the larger abscesses) has not changed much over last two decades. On the other hand, treatment of stage III (purulent peritonitis) and stage IV (feculent peritonitis) diverticulitis has evolved dramatically and remains morbid. In the 1980s a two stage procedure (1st - segmental sigmoid resection with end colostomy and 2nd - colostomy closure after three to six months) was standard of care for most general surgeons. However, it was recognized that half of these patients never had their colostomy reversed and that colostomy closure was a morbid procedure. As a result starting in the 1990s colorectal surgical specialists increasing performed a one stage primary resection anastomosis (PRA) and demonstrated similar outcomes to the two stage procedure. In the mid 2000s, the colorectal surgeons promoted this as standard of care. But unfortunately despite advances in perioperative care and their excellent surgical skills, PRA for stage III/IV diverticulitis continued to have a high mortality (10-15%). The survivors require prolonged hospital stays and often do not fully recover. Recent case series indicate that a substantial portion of the patients who previously were subjected to emergency sigmoid colectomy can be successfully treated with less invasive nonoperative management with salvage PCD and/or laparoscopic lavage and drainage. These patients experience a surprisingly lower mortality and more rapid recovery. They are also spared the need for a colostomy and do not appear to benefit from a delayed elective sigmoid colectomy. While we await the final results ongoing prospective randomized clinical trials testing these less invasive alternatives, we have proposed (based primarily on case series and our expert opinions) what we believe safe and rationale management strategy.

A multi-disciplinary review of the potential association between closed-suction drains and surgical site infection

BACKGROUND

Despite the putative advantages conferred by closed-suction drains (CSDs), the widespread utilization of post-operative drains has been questioned due to concerns regarding both efficacy and safety, particularly with respect to the risk of surgical site infection (SSI). Although discipline-specific reports exist delineating risk factors associated with SSI as they relate to the presence of CSDs, there are no broad summary studies to examine this issue in depth.

METHODS

The pertinent medical literature exploring the relationship between CSDs and SSI across multiple surgical disciplines was reviewed.

RESULTS

Across most surgical disciplines, studies to evaluate the risk of SSI associated with routine post-operative CSD have yielded conflicting results. A few studies do suggest an increased risk of SSI associated with drain placement, but are usually associated with open drainage and not the use of CSDs. No studies whatsoever attribute a decrease in the incidence of SSI (including organ/space SSI) to drain placement.

CONCLUSIONS

Until additional, rigorous randomized trials are available to address the issue definitively, we recommend judicious use and prompt, timely removal of CSDs. Given that the evidence is scant and weak to suggest that CSD use is associated with increased risk of SSI, there is no justification for the prolongation of antibiotic prophylaxis to "cover" an indwelling drain.

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.

Modified triangulating stapling technique for closure of a temporary loop stoma

PURPOSE

To describe a new stapling technique for closure of a temporary loop stoma and report the results of a retrospective investigation of its efficacy.

METHODS

Thirty-nine patients underwent a total of 40 loop stoma closure procedures, performed by the same surgeon using the same method, between 2004 and 2009. Thirty-six procedures were performed after rectal surgery, 1 was done for rectal malignant lymphoma, 2 were performed in the same patient after resection of rectal gastrointestinal stromal tumor, and 1 was performed after colonic surgery. The short-term outcomes were evaluated retrospectively. For this technique, after the minimum necessary dissection of both limbs of the bowel from the abdominal wall, the everted part of the oral limb is returned to its proper anatomy. The stoma is closed in the vertical direction using two lines of staples in an everted fashion.

RESULTS

The stoma was located in the terminal ileum (n = 36), transverse colon (n = 3), or sigmoid colon (n = 1). The mean operating time was 55 min and the estimated blood loss was 32 g. There were two postoperative wound infections and one anastomotic stenosis.

CONCLUSION

Stapling closure of a temporary loop stoma with two lines of staples may be a feasible alternative that decreases morbidity and reduces the operating time.

Endoscopy-based early enterostomy closure for superior mesenteric arterial occlusion

AIM: To evaluate the efficacy of endoscopic examination of blood flow and edema in the remnant bowel.

METHODS: We retrospectively studied 15 patients who underwent massive bowel resection with enterostomy for superior mesenteric arterial occlusion (SMAO); the patients were divided into a delayed closure group (D group) and an early closure group (E group).

RESULTS: The mean duration from initial operation to enterostomy closure was significantly shorter in the E group (18.3 ± 2.1 d) than in the D group (34.3 ± 5.9 d) (P < 0.0001). The duration of hospitalization after surgery was significantly shorter in the E group (33 ± 2.2 d) than in the D group (51 ± 8.9 d) (P < 0.0002).

CONCLUSION: Endoscopic examination of blood flow and edema in the remnant bowel is useful to assess the feasibility of early closure of enterostomy in SMAO cases.

Laparoscopic and open reversal of Hartmann's procedure--a comparative retrospective analysis

BACKGROUND

Restoration of intestinal continuity after Hartmann's procedure has traditionally required laparotomy. This study compares our experience with laparoscopic and open reversal of Hartmann's procedure.

STUDY DESIGN

All laparoscopic and open Hartmann's reversal procedures performed between January 1998 and June 2006 were reviewed. Patients with laparoscopic reversal were retrospectively matched by age, body mass index (BMI), and indication to controls with open reversal. Demographic data, perioperative course, and postoperative complications were documented.

RESULTS

We identified 41 patients who underwent laparoscopic reversal of Hartmann's procedure and these were matched to 41 patients with open reversal. The groups had similar average age and BMI. The predominant indication for surgery in both groups was diverticular disease. Conversion to laparotomy occurred in eight patients (19.5%), and was due to dense adhesions or difficulty in identification of the rectal stump. Adhesions were significantly greater in the conversion group (p <0.05), and the rectal stump was not marked in any of these cases. The most common short-term complications were ileus and surgical site infection. There were no anastomotic leaks and no mortalities. The mean operative times in the laparoscopic and open groups were 193 versus 209 min, respectively (p = 0.33). The laparoscopic group had a significantly lower estimated blood loss of 166 versus 326 mL (p < 0.0005), shorter time to bowel function return (4.1 versus 5.2 days, p < 0.05), and a shorter hospital stay (6.4 versus 8.0 days, p < 0.05). The major complication rate was also significantly lower in the laparoscopic group than in the open group (4.8% versus 12.1%, p < 0.05).

CONCLUSIONS

Laparoscopic reversal of Hartmann's procedure is a safe and practical alternative to open reversal. It can be performed with similar operative time, fewer complications, and a faster recovery time. Conversion during the reversal procedure was significantly impacted by severity of adhesions and marking of the rectal stump.

Laparoscopically assisted reversal of Hartmann's procedure

BACKGROUND

Restoration of bowel continuity after Hartmann's procedure is a major surgical procedure associated with substantial morbidity and occasional mortality. The authors review their experience with laparoscopically assisted reversal of Hartmann's procedure (LARH) to assess difficulties and potential advantages associated with this procedure.

METHODS

A retrospective chart review of a prospectively entered database was performed to identify patients who underwent LARH over a period of 7 years. Data regarding demographic and clinical characteristics, surgical details, and postoperative course were reviewed. Specifically, age, gender, diagnosis at initial operation, American Society of Anesthesiology (ASA) score, comorbidities, operative time, conversion, surgical team, complications, postoperative bowel movements, and hospital stay were assessed. All surgeries were performed by six experienced laparoscopic surgeons.

RESULTS

A total of 27 patients, 17 men and 10 women, with mean ages of 58.1 and 62.9 years, respectively, underwent LARH. The procedure was laparoscopically completed for 23 patients. Conversion to laparotomy was required for four patients (14.8%) because of dense adhesions after the initial Hartmann's procedure in three patients and rectal perforation in one patient. The median operative time was 226 min, and the median hospital stay was 6 days. The overall morbidity rate was 33% (9 patients), attributable to colostomy site infection in 5 of the 9 patients. One patient required reoperation because of intraabdominal bleeding. No anastomotic leaks or intraabdominal abscesses were recorded. There was no operative mortality.

CONCLUSIONS

Laparoscopically assisted reversal of Hartmann's procedure is technically challenging and time consuming. However, in the hands of experienced laparoscopic surgeons, it is safe and associated with a reasonably low conversion rate. Furthermore, the relatively low morbidity rate, short hospital stay, and earlier return of bowel function may be beneficial to patients.

A multivariate analysis of limiting factors for stoma reversal in patients with rectal cancer entered into the total mesorectal excision (TME) trial: a retrospective study

BACKGROUND

In many patients with rectal cancer, defunctioning stomas are created to limit the consequences of anastomotic leakage. Although intended to be temporary, a substantial proportion of these stomas might never be reversed for various reasons. We aimed to describe stoma policy by use of data from the total mesorectal excision (TME) trial in patients with rectal cancer and to identify factors that limit stoma reversal.

METHODS

924 Dutch patients with rectal cancer who underwent a low anterior resection were selected from the TME trial, a prospective, randomised multicentre trial studying the effects of short-term preoperative radiotherapy in 1861 patients who underwent TME. Creation of stomas and time to stoma reversal were analysed retrospectively by use of multivariate analysis.

FINDINGS

In 523 of 924 (57%) patients, a primary stoma (defined as a stoma created at the time of TME) was constructed after a low anterior resection. Geographical differences in the number of primary stomas constructed were reported throughout the Netherlands. 19% of stomas that were created were never reversed. Postoperative complications and secondary constructed stomas (defined as a stoma created during a second or subsequent procedure after TME) were associated with a high likelihood of a permanent stoma. However, perioperative complications were not a limiting factor for stoma closure.

INTERPRETATION

Postoperative complications are an important limiting factor for stoma reversal because, after occurrence of these complications, patients and surgeons might be reluctant to reverse the stoma, so a substantial proportion of these stomas are never closed. Future guidelines for stoma creation and closure should consider these factors.

Colon and rectal injuries

PURPOSE

This study was designed to develop treatment algorithms for colon, rectal, and anal injuries based on the review of relevant literature.

METHODS

Information was obtained through a MEDLINE ( www.nobi.nih.gov/entrez/query.fcgi ) search, and additional references were obtained through cross-referencing key articles cited in these papers.

RESULTS

A total of 203 articles were considered relevant.

CONCLUSIONS

The management of penetrating and blunt colon, rectal, and anal injuries has evolved during the past 150 years. Since the World War II mandate to divert penetrating colon injuries, primary repair or resection and anastomosis have found an increasing role in patients with nondestructive injuries. A critical review of recent literature better defines the role of primary repair and fecal diversion for these injuries and allows for better algorithms for the management of these injuries.

Predictors for Complications after Loop Stoma Closure in Patients with Rectal Cancer

PURPOSE

This unmatched case control study was undertaken to evaluate factors contributing to surgery-related complications of loop stoma closure in patients with rectal cancer.

METHODS

Cases were consecutive patients with complications identified from a local registry. Complications were defined as surgery-related and included 30 days overall mortality. Controls were all other patients with stoma closure from the same population of the registry without the endpoint.

RESULTS

Of the 243 patients, 47 (19%) patients experienced a surgery-related complication, including 5 patients who died within 30 days after surgery. Significant risk factors in the univariate analysis were supervised operation (odds ratio 0.50; 95% confidence interval 0.27-0.95; P=0.04), stapled anastomosis (odds ratio 0.40; 95% confidence interval 0.17-0.91; P=0.04) and using a soft silicone drain (odds ratio 2.03; 95% confidence interval 1.07-3.85; P=0.04). Using a soft silicone drain (odds ratio 2.17; 95% confidence interval 1.10-4.26; P=0.03) and stapled anastomosis (odds ratio 0.38; 95% confidence interval 0.15-0.98; P=0.04) were the only significant predictors in the multivariate analysis.

CONCLUSIONS

The present study in a homogeneous group of patients with rectal cancer as elective indication for temporary loop stoma construction confirms the high complications rate and mortality rate associated with stoma closure. Intraperitoneal drains should be omitted after loop stoma closure.

Morbidity of temporary loop ileostomy in patients with colorectal cancer

PURPOSE

This study was designed to quantify the temporary loop ileostomy-related morbidity in patients with colorectal cancer and contrast the morbidity rates after ileostomy closure before, during, and after the start of adjuvant therapy.

METHODS

Between 1997 and 2004, 120 patients with colorectal carcinoma underwent colorectal resection and creation of a temporary loop ileostomy to protect the low anastomosis. Stoma-related complications and perioperative morbidity after ileostomy closure were assessed retrospectively by reviewing the medical records.

RESULTS

Sixteen of the 120 patients (13.3 percent) suffered stoma-related complications, requiring early ileostomy closure in three. After ileostomy closure, anastomotic leakage of the ileoileostomy occurred in 3 of the 120 patients (2.5 percent), 2 of them died postoperatively (1.7 percent). The rate of minor complications (16.7 percent in all patients) was much higher in patients undergoing adjuvant chemotherapy or radiochemotherapy (25.5 percent) than in patients receiving no additional therapy (9.2 percent). In the former patients, there was a trend toward fewer complications when ileostomy closure was performed before (12.5 percent), rather than during (42.9 percent) or after (21.2 percent), the start of adjuvant therapy.

CONCLUSIONS

The morbidity following closure of a temporary loop ileostomy in colorectal cancer patients is much higher in patients receiving adjuvant chemotherapy or radiochemotherapy. The morbidity, however, might possibly be lowered to the level of patients receiving no additional therapy if ileostomy closure is performed before the start of adjuvant therapy.

Dual endoscopic-assisted endoluminal colostomy reversal: a feasibility study

BACKGROUND

Emergent colostomies are associated with increased morbidity related to second closure operations. The purpose of this canine pilot study was to create a minimally invasive procedure that would reduce the time interval and morbidity involved with colostomy reversals after left colon end colostomies.

METHODS

Six mongrel dogs underwent modified laparoscopic Hartmann's procedures in which the stapled end of the rectal stump was approximated to the left colon proximal to the stoma. After 1 week, they underwent an endoluminal colostomy reversal with a computer-mediated, circular stapling device and varying anvil insertion methods. Variables recorded included anvil insertion technique and feasibility, OR time, complications, and number of days to first meal and bowel movement. A contrast enema performed 1 week post colostomy reversal ruled out anastomosis leaks and stenosis. The dogs were euthanized and subjected to necropsy.

RESULTS

Of four anvil insertion techniques tested, the most feasible employed a large-bore needle to perforate through the stapled end of the Hartmann pouch into the lumen of the left colon. Simultaneous endoluminal views of the rectal stump with a sigmoidoscope and the left colon lumen with an endoscope permitted a controlled and safe needle puncture. Through the needle, a guide wire was inserted to withdraw the anvil via the colostomy into place. A transanally inserted stapler was then married to the anvil under fluoroscopic guidance, thus completing the anastomosis. The colostomy was then taken down and transected at the level of the colocolostomy. Average operating time was 126 min (range 90-180), diet was tolerated within 1.5 days, and average number of days to first bowel movement was 2.5. The absence of stenosis, leaks, and inadvertent visceral injuries confirmed feasibility.

CONCLUSIONS

In this canine model, a dual endoscopic-assisted colostomy reversal with a computer-mediated, circular stapling device is feasible. Using this technique, colostomy reversals can possibly be performed 1 week post-colostomy without entering the peritoneal cavity, thus reducing the number of invasive operations and subsequent morbidity required to manage emergent colon perforations.

A technique for wound closure that minimizes sepsis after stoma closure

BACKGROUND

The aim of the present study was to assess the incidence of wound sepsis following closure of ileostomies and colostomies in our institution.

METHODS

Circumferential subcuticular wound approximation was used in 51 patients in our institution. Evidence of wound sepsis (assessed by the presence of cellulitis, induration and or purulent discharge) was documented both in the postoperative period and in outpatient follow-up.

RESULTS

A wound infection rate of 0% was achieved, both in the immediate postoperative period and upon 6-week follow-up.

CONCLUSIONS

Circumferential subcuticular wound approximation is, therefore, a safe and efficacious technique for dealing with the skin wound after stomal closure, virtually abolishing wound sepsis.

Fechamento precoce das colostomias em pacientes com trauma do reto: um estudo prospectivo e casualizado

Foi feito um estudo prospectivo e casualizado de 35 pacientes portadores de colostomias devido a lesões traumáticas do reto admitidos no Hospital Jõao XXIIII no período de novembro de 1994 a junho de 1997. O objetivo foi avaliar os resultados do fechamento precoce das colostomias nestes pacientes. Após o atendimento inicial, os pacientes foram sorteados de acordo com o número do registro de admissão em dois grupos: os do grupo 1 (N = 14) foram submetidos ao fechamento precoce da colostomia programado para o 10º dia pós-operatório do tratamento da(s) lesão(ões) e os do grupo 2 (N = 21) submetidos ao fechamento tardio da colostomia, programado para oito semanas após a operação inicial. Nos dois grupos, o restabelecimento do trânsito intestinal somente foi realizado após o fechamento da lesão retal confirmado por um estudo radiológico contrastado. Houve um predomínio de pacientes jovens, do sexo masculino e vítimas de traumatismo penetrante. Todos eram portadores de uma colostomia em alça. A taxa global de complicações após o fechamento das colostomias foi de 25,7%, com a infecção de ferida operatória sendo a complicação mais freqüente (17,1%). No grupo 1, as complicações ocorreram em 35,7% dos casos e, no grupo 2, em 19,1% (p = 0,423). A análise dos resultados permitiu-nos concluir que a taxa de complicações, a duração da operação para o fechamento da colostomia e o tempo total de permanência hospitalar não apresentaram diferenças significantes entre os dois grupos. Os pacientes submetidos ao fechamento precoce (grupo 1) permaneceram apenas 10 dias em média com a colostomia, enquanto nos pacientes do grupo 2 a média de permanência com a colostomia foi de 66,3 dias (p< 0,001 - Teste de Kruskal-Wallis). Baseados nestes resultados, concluímos que os pacientes portadores de colostomias utilizadas para o tratamento de lesões traumáticas do reto e que não apresentem complicações da operação inicial, poderão ser submetidos ao seu fechamento a partir do 10ºDPO da operação inicial.

Colostomy Closure: Impact of Preoperative Risk Factors on Morbidity

The objective of this study was to stratify patients for colostomy closure into risk categories according to preoperative variables. This was a retrospective case series. Median follow-up was 82 months. A tertiary care academic medical center was the setting for this study. A study sample of 155 consecutive patients who underwent colostomy closure at a single institution between 1985 and 1995 were included in this study. The following preoperative variables were analyzed: indication for colostomy fashioning; age; gender; American Society of Anesthesiology (ASA) class; presence of cardiac, renal, or pulmonary dysfunctions; presence of diabetes mellitus; and immunosuppression. The occurrence of adverse outcome, as evidenced by postoperative morbidity and mortality, was used as the main outcome measure. Complications occurred in 49 patients (31.6%), including a 1.3 per cent mortality. There was a trend of increasing morbidity with increasing ASA class. The single factor that showed a statistically significant increase in morbidity was the presence of diabetes (P = 0.036). Predicted probabilities of complications for patients with ASA HI with renal disease was 31 per cent, increased to 47.9 per cent if cardiac disease was also present and to 77 per cent with the addition of diabetes. The presence of diabetes carries an independent risk factor for adverse outcome in colostomy closure. This study provides information about stratification of postoperative risk based on commonly available preoperative variables. In the majority of cases, colostomy closure seems to carry a very acceptable complication rate. In selected patients with multiple preoperative risk factors, the morbidity becomes significantly higher.

Complications of abdominal stoma surgery

PURPOSE

This study was undertaken to review and summarize the complications of ileostomy and colostomy creation and subsequent closure.

METHODS

The English-language medical literature for at least the past 15 years was reviewed comprehensively.

RESULTS

Complications of surgery for the creation of end, loop, and "end loop" stomas are presented. Technical factors, which might influence complication rates, are discussed. Optimal management of ostomy complications is presented, especially for peristomal hernias. Similarly, techniques and complications for stoma closure are analyzed.

CONCLUSIONS

Stoma creation is not a trivial undertaking; careful surgical technique minimizes complications (which are relatively frequent), and promotes good ostomy function. Peristomal hernias are difficult to cure permanently. The morbidity of ileostomy and colostomy closure is also appreciable.

Primary repair for colonic gunshot wounds

BACKGROUND

Penetrating injuries of the colon have been managed traditionally by diverting colostomy. Recently, a trend towards primary repair has been observed, particularly for knife injuries. The purpose of this study is to evaluate the safety of primary repair for colonic gunshot wounds in the presence of certain clinical risk factors.

METHODS

A retrospective analysis of 223 patients with colonic bullet injuries in a period of 3 years (1990-93) was performed.

RESULTS

Of 223 patients with colonic trauma, 168 were primarily repaired (group A) and 55 underwent a colostomy (group B). Intra-abdominal septic complications occurred in 5.9% of group A patients and 10.9% of group B patients (P > 0.05, NS). These patients were, furthermore, stratified according to well-known risk factors for the development of complications, namely, site of injury, presence of shock on admission, degree of faecal contamination and number of associated injuries. We were unable to find any statistically significant differences in intra-abdominal septic complication rates between patients treated with primary repair and patients treated with colostomy.

CONCLUSIONS

Primary repair seems to be a safe therapeutic option for gunshot wounds of the colon. Even in the presence of the above-mentioned risk factors, colostomy may be avoided in most cases as primary repair does not appear to be associated with higher complication rates.

Colostomy closure. Ochsner Clinic experience

PURPOSE

We retrospectively reviewed the records from our past five years of experience with colostomy closure at a large multispecialty hospital to determine postoperative morbidity.

RESULTS

From March 1988 to April 1993, 46 patients underwent colostomy closure. Patients ranged in age from 24 to 87 (mean, 41.8) years, and 25 (54 percent) were women. Stomas had been created during emergency operations in 40 patients (87 percent); most operations (54 percent) were for complications of acute diverticulitis. Of the 46 procedures, 40 (87 percent) were end colostomies, and 6 were loop colostomies. Stomas were closed at a range of 11 to 1,357 days after creation (mean, 207 days; median, 116 days). Twenty-six patients (57 percent) underwent colostomy closure alone, and the remainder underwent additional procedures ranging from appendectomy to hepatic lobectomy. Duration of operations ranged from 1 to 9.5 (mean, 4.2) hours, and estimated blood loss averaged 400 ml. Overall hospital stay for closure was 6 to 62 (mean, 11.5) days. Inpatient complications occurred in 15 percent of patients, including congestive heart failure (2 percent), cerebrovascular accident (4 percent), pneumonia (2 percent), enterocutaneous fistula (2 percent), and pulmonary embolus with death (2 percent). The most common long-term complication was midline wound hernia, which occurred in 10 percent of surviving patients. Overall, complications occurred in 24 percent.

CONCLUSIONS

Colostomy closure is a major operation; however, with good surgical judgement and technique, associated morbidity and mortality can be minimized.

Laparoscopic-assisted colostomy closure after Hartmann's procedure

PURPOSE

The aim of the study was to review our experience with colostomy closure after Hartmann's procedure and the possible impact of laparoscopic colostomy closure.

METHODS

A retrospective review of hospital stay after colostomy closure by laparotomy in the last four years was conducted. A chart review of patients undergoing laparoscopic colostomy closure after Hartmann's procedure since the introduction of operative laparoscopy at our institution was also done.

RESULTS

One hundred twenty patients had colostomy closure carried out by the trauma service at the University of Miami/Jackson Memorial Hospital. In thirty-seven patients, colostomy closure was associated with other surgical procedures such as ventral herniorrhaphy, delayed closure of the open abdomen, ureteroneocytostomy, and so forth, or they underwent loop colostomy closure. These patients were excluded from further review. Sixty-five patients underwent reversal of Hartmann's procedure by laparotomy. They had an average hospital stay of 9.5 days (range, 6 to 34 days). This group of patients had colostomy closure prior to the introduction of operative laparoscopy in our institution. With increased laparoscopy experience, laparoscopically assisted Hartmann's reversal has been attempted in 18 patients and completed in 14 patients. The average hospital stay in the laparoscopically completed group was 6.3 days (range, 4 to 10 days). This group had a 0 percent mortality and a 14.3 percent morbidity. This compares favorably to recently reported series of colostomy closure by laparotomy.

CONCLUSION

Laparoscopically assisted Hartmann's reversal results in comparable morbidity, but may be associated with shorter hospital stay when compared with laparotomy.

Same admission colostomy closure (SACC). A new approach to rectal wounds: a prospective study

OBJECTIVE

The purposes of this project were to study the healing of protected rectal wounds (RWs) using contrast enemas (CEs) and to establish the safety of same admission colostomy closure (SACC) in terms of colostomy closure (CC) and rectal wound-related outcomes, for selected patients with radiologically healed RWs.

SUMMARY BACKGROUND DATA

Traditional treatment of RWs has included a diverting colostomy that is closed 2 or more months later during a readmission.

METHODS

All patients admitted with a rectal injury were entered into this prospective study, treated with a diverting colostomy and presacral drainage, and managed according to a postoperative protocol that included a CE per anus to detect healing of the RW. Patients with no leaking on their first CE, no infection, and anal continence underwent SACC.

RESULTS

From 1990 to 1993, 30 consecutive patients had rectal injuries, 90% of which resulted from gunshot wounds. The first CE was performed in 29 patients 5 to 10 days after injury. In this group, 21 patients did not and 8 did have leakage from their RWs. The proportions of RWs radiologically healed at 7 and 10 days after injury were 55.2% and 75%, respectively. Sixteen patients with a normal CE underwent SACC 9 to 19 days after injury (mean, 12.4 days). There were two fecal fistulas (2 of 7; 28.6%) after simple suture closure, none (0 of 9) after resection of the stoma with end-to-end anastomosis, and no RW-related complications after SACC. The mean hospitalization time was 17.4 days.

CONCLUSIONS

The following conclusions were drawn: (1) CE confirmed healing of RWs in 75% of patients by 10 days after injury; (2) 60% of patients with RWs were candidates for SACC, and 53% were discharged with their colostomies closed; (3) SACC was performed without complications in 87.5% of patients with radiologically healed RWs; and (4) there were no RW-related complications after SACC.

Morbidity and timing of colostomy closure in trauma patients

The reported morbidity of colostomy closure in trauma patients varies from 5 to 27 per cent. Low morbidity rates are cited as a factor favouring colostomy creation and against expanded indications for primary repair in the treatment of colonic injuries. In order to assess the morbidity of colostomy closure, we reviewed all colonic injuries from 1979 to 1991 at our institutions. In all, 86 trauma patients who underwent colostomy creation and closure were identified. There were 82 men and four women with an age range of 16 to 74 years (mean 28.1 years). Of these, 95 per cent (N = 82) resulted from penetrating trauma. Of the patients, 63 per cent (N = 54) received end colostomies and 81 per cent (N = 70) of the patients had associated injuries. Of the patients, 38 per cent (N = 33) had a complication with their initial operation. There were no deaths after colostomy closure, but a total morbidity of 24.4 per cent (N = 21) was noted. There were 11 anastomotic complications (two of which required repeat laparotomy) and nine wound infections. The average length of stay was 10.4 days. Morbidity was concentrated in the group who had complications at their initial hospitalization. This was especially true if these patients underwent closure earlier than 3 months after injury. Conversely, if the first operation was uncomplicated, waiting longer than 3 months to perform colostomy closure did not improve results further.

The present role of colostomy in the management of trauma

The role of colostomy in the treatment of abdominal trauma has changed over the past several decades. Primarily as a result of its successful use in military settings, colostomy initially was the mainstay of treatment for penetrating injury to the colon, rectal injury, and some forms of blunt trauma. Subsequent civilian experience with the techniques of primary repair of penetrating colon injury resulted in a decrease in the number of colostomies performed. Coupled with this experience, early data on adverse outcome from colostomy closure tended to support the trend of the ever-diminishing place of colostomy for trauma. Colostomy has always been used for two purposes in trauma care: prevention or arrest of fecal contamination of the peritoneal cavity and diversion of the fecal stream. Despite the decreased need for colostomy in some forms of penetrating colon injury, there are several conditions that still utilize colostomy to accomplish one or both of these purposes. Indications for colostomy can now be regarded as absolute or relative depending upon the need for diversion or the requirement to prevent contamination. There are relatively few contraindications to colostomy use. Present results of colostomy closure do not represent excessive risk to the patient and should not impact negatively on the decision to perform a colostomy for trauma.

New technique for Hartmann's reconstruction

Since the introduction of Hartmann's operation and its broader applications, restoration of intestinal continuity has posed technical challenges and significant morbidity. We describe a technique for Hartmann's reconstruction, utilizing a circular anastomotic stapling device that is simple and fast and that minimizes the potential for contamination, in which the bowel lumen remains closed at all times.

Protective colostomy closure: the hazards of a "minor" operation

A retrospective study of 87 patients, subjected to colostomy closure between 1976 and 1987, was conducted in order to evaluate the role of 8 potential risk factors on morbidity and mortality. Possible risk factors were age greater than 65 years, presence of hypoalbuminaemia (less than 3.0 gr%), anaemia (Hb less than 10 gr%), operative technique, duration of colostomy, site of colostomy, underlying disease and presence of subcutaneous drainage. Apart from hypoalbuminaemia, no clear risk factor was identified, although an interval of more than 90 days between construction and closure of colostomy appears to be safer than shorter intervals. A comparison was also made between two different periods from 1976 to 1982 and from 1983 to 1987 which resulted in important changes in patient management in the second period including: type of antibiotic prophylaxis, type of anastomosis and suture material, site of colostomy and mean duration of colostomy. Four post-operative deaths (4.6%) (two for myocardial insufficiency and two for sepsis), 11 major (13%) and 25 (29%) minor complications were recorded. The analysis of the two different periods showed a strong reduction in both mortality and morbidity in the second period, which could be related to a better management of this type of patient. In conclusion, the incidence of mortality and morbidity in colostomy closure cannot be underestimated and therefore the same skill and meticulous approach are required for this operation as for any major surgical procedure on the colon.
