Retained staples causing rectal bleeding and severe proctalgia after the STARR procedure

Does the removal of retained staples really improve postoperative chronic sequelae after transanal stapled operations?

BACKGROUND

Transanal stapled procedures are increasingly being used. Several postoperative complications can be referred to their application, including those related to the presence of retained staples at the level of the staple line.

OBJECTIVE

This study was conducted to assess whether the removal of the retained staples is a useful approach to improve some of the most common postoperative complications of these surgical techniques.

DESIGN

This is a retrospective study.

SETTINGS

The study was conducted at the One-Day Surgery Unit of St. Andrea Hospital.

PATIENTS

All of the patients who underwent a stapled transanal procedure from January 2003 to December 2011 were included in the study. Patients included in the study were followed postoperatively for 1 year after surgery to identify the presence of retained staples.

INTERVENTIONS

If identified, the retained staples were removed endoscopically or transanally.

MAIN OUTCOME MEASURES

After the staple removal, patients were followed with biweekly office visit for 2 months to evaluate the progression of symptoms.

RESULTS

From the 566 patients included in the study, 165 experienced postoperative complications, and in 66 of these cases, retained staples were found and removed. With the removal of retained staples, symptoms were almost all resolved or improved. In only 1 case did the retained staples removal not modify the symptoms.

LIMITATIONS

The study design may have introduced potential selection bias. In addition, the study was limited by the lack of a specific questionnaire for the evaluation of symptoms improvement.

CONCLUSIONS

The removal of the retained staples is an efficacious and safe procedure to solve or improve postoperative complications and should be always considered.

Agraffectomy after low rectal stapling procedures for hemorrhoids and rectocele

BACKGROUND

Various sequelae which might lead to reintervention have been described after stapled rectal mucosectomy for hemorrhoids. One potential treatment modality for persistent complaints after stapled hemorrhoidopexy (SHP) or stapling for rectocele is the so-called agraffectomy (removal of the retained staples). This treatment option means a further procedure that can range from removal of the staples through the anoscope to removal of the entire staple line with the associated scar tissue.

METHODS

In order to review the published literature, we conducted a search on Medline, Pubmed, and Embase using different terms for "agraffectomy."

RESULTS

Overall, fourteen reports were found, dealing with agraffectomy for various conditions after low rectal stapling for hemorrhoids or rectocele. Agraffectomy is a rarely mentioned treatment option for conditions after SHP. In rectal stenosis with complete occlusion of the rectal lumen, the removal of the stenotic anastomosis and remaining staples seems to be reasonable. The same can be said of the removal of retained staples for rectal bleeding or in order to avoid penile injuries in anal intercourse. In contrast, the collected published reports on agraffectomy in this review only provide low-level evidence that this procedure provides relief for other problems such as incontinence or chronic pain.

CONCLUSIONS

There is no clear evidence that agraffectomy is indicated if not in case of rectal stenosis and hemorrhage caused by the staples.

Doppler-guided hemorrhoidal artery ligation: the experience of a single institution

PURPOSE

This study aims to review the short-term recurrence and complications of Doppler-guided hemorrhoidal artery ligation (DG-HAL) with mucopexy.

METHODS

Approval was obtained for a retrospective chart review of patients who underwent DG-HAL from January 2007 to June 2009. A treatment failure was recorded if internal hemorrhoids were noted at follow up or symptoms persisted. All recurrences were assessed for predictive factors.

RESULTS

The procedures were performed by four surgeons. Ninety-six patients were included. The average age was 63.5 years (21-81 years). The mean follow up was 15 months (3-35 months). Of the patients, 93 (96.8%) reported bleeding pre-operatively. Mucopexy accompanied DG-HAL in 87 (90.6%). Postoperative complications occurred in nine (9%) patients. Residual hemorrhoids were evident in 20 (21%) patients, 13 of whom required further management for symptomatic disease, five with DG-HAL. Fifty percent (10/20) and 70% (9/13) of the recurrences necessitating further treatment transpired during the first 20 procedures of each surgeon. All 13 symptomatic recurrences demonstrated large, circumferential internal hemorrhoids.

CONCLUSIONS

DG-HAL is a simple procedure with a low complication rate. Recurrences are more frequent during the learning curve. Patients with large, circumferential internal hemorrhoids should be counseled about a possible higher rate of recurrence. DG-HAL can be effectively repeated for recurrences.
