Intraperitoneal Tramadol in Abdominal Surgery: A Systematic Review.

BACKGROUND: Multimodal analgesic regimes are required to treat pain. Intraperitoneal (IP) agents, such as local anesthetics (LAs), have been shown to reduce pain after abdominal surgery. Other IP analgesics have been tested in several randomized control trials (RCTs), but no reviews or guidelines have evaluated their use. Tramadol is an effective oral and intravenous analgesia with recent evidence supporting the use of IP tramadol (IPT). We aimed to review the efficacy of IPT as an adjunct to intraperitoneal local anesthetics (IPLAs) for pain relief after abdominal surgery. MATERIALS AND METHODS: Relevant articles were identified by two independent reviewers from MEDLINE, EMBASE and PubMed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines up to January 2019. Only RCT comparing IPT + IPLA with IPLA alone were included. Outcomes recorded were the postoperative analgesic requirement, pain scores at 4 h and 24 h and adverse events. Data were analyzed with Review Manager, version 5.3. RESULTS: A total of five RCTs (4× laparoscopic cholecystectomy and 1× abdominal hysterectomy) were included in this review from 419 studies screened. All doses were given as a single bolus. Pain relief requirements over the first 24 h weres less in the IPT + IPLA groups when compared with those in IPLA alone. Pain scores were less for IPT + IPLA groups at 4 h and 24 h. There were no significant differences in adverse events between groups. CONCLUSIONS: In summary, IPT, in combination with IPLA, is effective in the management of acute postoperative pain and reduces the total amount of pain relief consumed in the first 24 h after surgery. Studies reporting the use of IPT + IPLA reported no toxicity or systemic adverse events. Further research into standardizing the dosing of IPT to optimize its effectiveness and further reduce the additional analgesic requirement is indicated.

Topical analgesia following excisional haemorrhoidectomy: a systematic review and meta-analysis of randomised controlled trials.

PURPOSE: Post-operative pain following excisional haemorrhoidectomy poses a particular challenge for patient recovery, as well as a burden on hospital resources. There appears to be an increasing role for topical agents to improve this pain, but their efficacy and safety have not been fully assessed. This systematic review aims to assess all topical agents used for pain following excisional haemorrhoidectomy. METHODS: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two authors independently assessed MEDLINE, EMBASE, and CENTRAL databases to 27 June 2019. All randomised controlled trials (RCTs) in English that investigated topical agents following excisional haemorrhoidectomy were included. Meta-analysis was performed using Review Manager, version 5.3. RESULTS: A total of 3639 records were identified. A final 32 RCTs were included in the qualitative analysis. Meta-analysis was performed on 9 RCTs that investigated glyceryl trinitrate (GTN) (5 for diltiazem, 2 for metronidazole and 2 for sucralfate). There were mixed significant changes in pain for GTN compared with placebo. Diltiazem resulted in significant reduction of pain on post-operative days 1, 2, 3 and 7 (p < 0.00001). Metronidazole resulted in significant reduction of pain on days 1 (p = 0.009), 7 (p = 0.002) and 14 (p < 0.00001). Sucralfate resulted in signification reduction of pain on days 7 and 14 (both p < 0.00001). CONCLUSION: Topical diltiazem, metronidazole and sucralfate appear to significantly reduce pain at various timepoints following excisional haemorrhoidectomy. GTN had mixed evidence. Several single trials identified other promising topical analgesics.

Local Anaesthesia Alone Versus Regional or General Anaesthesia in Excisional Haemorrhoidectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Excisional haemorrhoidectomy has been traditionally performed under general or regional anaesthesia. However, these modes are associated with complications such as nausea, urinary retention and motor blockade. Local anaesthesia (LA) alone has been proposed to reduce side effects as well as to expedite ambulatory surgery. This systematic review aims to assess LA versus regional or general anaesthesia for excisional haemorrhoidectomy. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE, EMBASE and CENTRAL databases were searched to 13 January 2020. All randomised controlled trials comparing LA only versus regional or general anaesthesia in patients who received excisional haemorrhoidectomy were included. The main outcomes included pain, adverse effects and length of stay. RESULTS: Nine trials, consisting of six studies comparing local versus regional anaesthesia and three comparing LA versus general anaesthesia, were included. Meta-analysis showed a significantly lower relative risk for need of rescue analgesia (RR 0.32 [95% CI 0.16-0.62]), intra-operative hypotension (RR 0.17 [95% CI 0.04-0.76]), headache (RR 0.13 [0.02-0.67]) and urinary retention (RR 0.17 [95% CI 0.09-0.29]) for LA when compared with regional anaesthesia. There was mixed evidence for both regional and general anaesthesia in regard to post-operative pain. CONCLUSIONS: LA alone may be considered as an alternative to regional anaesthesia for excisional haemorrhoidectomy with reduced complications and reduction in the amount of post-operative analgesia required. The evidence for LA compared to general anaesthesia for haemorrhoidectomy is low grade and mixed.

Pilonidal sinus: is histological examination necessary?

BACKGROUND: Pilonidal sinus is a common pathology occurring in a number of sites including the gluteal cleft between the buttocks. Surgery is the principal mode of treatment with a variety of techniques proposed to cure the disease and prevent recurrence. The rate of malignant degeneration is estimated at 0.1% in patients with chronic pilonidal disease. A case series study of pilonidal sinus found that most patients with malignancy were over the age of 50 years and had had chronic pilonidal disease for several years. This study aimed to review the value of histological analysis of pilonidal sinus specimens. METHODS: A retrospective observational study was conducted of all patients who have undergone pilonidal sinus excision by the Department of General Surgery at Counties Manukau District Health Board in the past 10 years. RESULTS: This study reviewed 1324 admissions with a pilonidal disease requiring surgical management. There were 325 pilonidal resections with 320 histological specimens analysed. Pilonidal sinus was detected in 312 specimens, eight others were benign and there were no specimens with malignancy. CONCLUSION: No cases of malignancy were found in all pilonidal specimens that were sent for histological review. Routine histological examination of pilonidal sinus specimens appears to be unnecessary; however, it should be considered in patients over the age of 50 years.

Prophylactic Foley catheter insertion into defunctioning ileostomy to reduce obstruction after colorectal surgery: pilot randomized controlled trial.

BACKGROUND: Defunctioning ileostomies provide faecal diversion in major colorectal surgery. This reduces the consequences of an anastomotic leak. However, the formation of an ileostomy carries risks including obstruction at the level of the fascia. Post-operative oedema at the level of the fascia may contribute to obstruction. We hypothesize that the prophylactic insertion of a Foley catheter into the afferent limb of a defunctioning loop ileostomy may help decompress and improve time to low-residue diet (LRD). The objective of the study was to assess the feasibility of a Foley catheter, prophylactically inserted into the afferent limb of a defunctioning loop ileostomy, after major colorectal surgery. METHODS: The study was a prospective pilot-randomized controlled trial. Ethical approval was obtained from Northern B Health and Disability Ethics Committee 15/NTB/91 ANZCTR Trial ID: ACTRN12615000691549. RESULTS: Forty-nine patients undergoing major elective colorectal surgery with a defunctioning ileostomy, between the years of 2015 and 2018 at North Shore Hospital, Auckland, New Zealand were included in this study. Patients were randomly allocated to either the Foley catheter (n = 26) or non-Foley catheter (n = 23) group. The median time taken to tolerate LRD the primary outcome, was 2 days in the Foley group versus 2 days in the non-Foley group (P = 0.05). There were no differences in the secondary outcome measures such as time to stoma output, length of stay or complications. CONCLUSION: This trial failed to show a statistical difference in time taken to tolerate a LRD residue in the Foley catheter group. There was no difference in length of stay, time to flatus or stoma output.

Patient information needs in upper gastrointestinal cancer: what patients and their families want to know.

BACKGROUND: The treatment of upper gastrointestinal cancer (UGIC) patients is complex. Patients are often elderly, comorbid as well as nutritionally depleted and treatment involves multimodality therapy incorporating chemotherapy, radiation therapy and surgery. The pre-treatment information requirements of UGIC patients are not clear but crucially important in ensuring they complete treatment successfully. METHODS: A systematic review of the English language literature was performed to determine the specific information needs of patients with UGIC. RESULTS: Following abstract review and comprehensive analysis six articles were included. UGIC patients nominated information regarding post-operative recovery, quality of life, expected survival, management of post-operative symptoms and coping strategies for insurance and financial issues, relationships and family as being most important to them. Patients' families nominated information on the effects of diagnosis on patient well-being over the ensuing months and detailed information on available support services as being most important. One-on-one consultations with senior medical staff were the preferred method of information transfer followed by web-based information services. CONCLUSIONS: For effective treatment of UGIC patients, physicians and surgeons must address issues pertaining to quality of life, finance and relationships and may require specific training, or administrative support, in these areas.
