Comprehensive literature review of the applications of surgical laser in benign anal conditions.

Surgery for benign anal conditions is a common practice and is usually followed by a good outcome. The present review aimed to summarize the emergence and evolution of different laser techniques used for the treatment of benign anal conditions and report their current outcome. PubMed and Scopus were searched for studies that assessed the use of laser in benign anal conditions. Anal conditions reviewed were hemorrhoids, anal fistula, anal warts, anal stenosis, and anal fissure. The full text of the studies retrieved was summarized in a narrative and tabular form. Laser techniques used for the treatment of hemorrhoidal disease were laser open hemorrhoidectomy, laser hemorrhoidoplasty, and Doppler-guided hemorrhoidal laser dearterialization. Resolution of hemorrhoidal symptoms was reported in 72-100% of patients after laser treatment. YAG laser, fistula laser closure, and photodynamic therapy have been used for the treatment of anal fistula with success rates ranging from 20 to 92.6%. Anal warts can be treated with photodynamic therapy with or without YAG or CO2 laser with a success rate up to 88%. A few studies reported the use of laser in the treatment of chronic anal fissure and anal stenosis. The use of laser in the treatment of benign anal conditions is associated with promising outcomes. Laser was most assessed in hemorrhoidal disease and anal fistula and showed more consistent success rates with hemorrhoidal disease than with anal fistula. Preliminary reports assessed the outcome of laser treatment in other conditions as anal fissure and warts with acceptable outcomes.

Literature review of the outcome of and methods used to improve transperineal repair of rectocele.

BACKGROUND: Rectocele is commonly seen in parous women and sometimes associated with symptoms of obstructed defecation syndrome (ODS). AIM: To assess the current literature in regard to the outcome of the classical transperineal repair (TPR) of rectocele and its technical modifications. METHODS: An organized literature search for studies that assessed the outcome of TPR of rectocele was performed. PubMed/Medline and Google Scholar were queried in the period of January 1991 through December 2020. The main outcome measures were improvement in ODS symptoms, improvement in sexual functions and continence, changes in manometric parameters, and quality of life. RESULTS: After screening of 306 studies, 24 articles were found eligible for inclusion to the review. Nine studies (301 patients) assessed the classical TPR of rectocele. The median rate of postoperative improvement in ODS symptoms was 72.7% (range, 45.8%-83.3%) and reduction in rectocele size ranged from 41.4%-95.0%. Modifications of the classical repair entailed omission of levatorplasty, addition of implant, concomitant lateral internal sphincterotomy, changing the direction of plication of rectovaginal septum, and site-specific repair. CONCLUSION: The transperineal repair of rectocele is associated with satisfactory, yet variable, improvement in ODS symptoms with parallel increase in quality-of-life score. Several modifications of the classical TPR were described. These modifications include omission of levatorplasty, insertion of implants, performing lateral sphincterotomy, changing the direction of classical plication, and site-specific repair. The indications for these modifications are not yet fully clear and need further prospective studies to help tailor the technique to rectocele patients.

Sinus laser therapy versus sinus lay open in the management of sacrococcygeal pilonidal disease.

AIM: There is no standard method for the management of sacrococcygeal pilonidal disease (SPND); however, surgery remains the gold standard treatment. Wide surgical excision of the sinus is the traditional surgical treatment of SPND, yet it is associated with extended healing time and delayed recovery. This study aimed to compare the outcomes of sinus laser therapy (SiLaT) and sinus lay open in the management of SPND. METHODS: Patients with SPND who were treated with SiLaT or lay open were retrospectively reviewed. The main outcome measures were the success of surgery in terms of complete healing at 12 months postoperatively, time to complete healing, complications, operation time and quality of life (QoL). RESULTS: A total of 139 patients with a mean age of 25 years were included to the study. Sixty-two patients underwent SiLaT and 77 underwent lay open. Six patients experienced recurrence after SiLaT while there was no recorded recurrence after the lay open technique (P = 0.007). Sinus lay open had a shorter operation time than SiLaT (P < 0.0001). On the other hand, SiLaT was followed by a shorter healing time, lower incidence of delayed wound healing, better cosmetic outcome, and higher QoL scores compared to the lay open group. The complication rates were comparable between the two groups. CONCLUSION: Sinus lay open was associated with better success than SiLaT. On the other hand, SiLaT was associated with quicker healing, better cosmesis, better QoL and longer operation time. The complication rate of the two procedures was comparable.

Partial Division of Puborectalis Muscle with Lateral Internal Sphincterotomy: A Novel Surgical Technique for Management of Anal Hypertonia-Associated Anismus.

BACKGROUND: Treatment of anismus usually starts with biofeedback therapy and injection of botulinum toxin in the puborectalis muscle (PRM). Patients refractory to conservative treatment may require surgery. The present cohort study aimed to assess a combined technique of partial division of PRM and tailored lateral internal sphincterotomy (LIS) in treatment of anismus. METHODS: Patients with anismus who failed conservative treatments were assessed clinically and with high-resolution anal manometry (HRAM), EMG, defecography, and underwent combined partial division of PRM on one side and tailored LIS on the contralateral side. Main outcome measures were improvement in symptoms and quality of life, changes in HRAM and defecography postoperatively, complications, and patient satisfaction. RESULTS: A total of 73 patients (61 male) of a mean age of 37 years were included to the study. In total, 89% of patients showed a significant improvement in symptoms at 12 months postoperatively. The mean modified Altomare score decreased significantly (p < 0.0001) from 16.4 ± 1.7 to 6.6 ± 1 at 12 months postoperatively. There was a significant increase in the mental and physical components of quality of life at 12 months postoperatively. The numbers of patients with positive findings of anismus in postoperative defecography, EMG, and balloon expulsion test were significantly less than before surgery. The mean total satisfaction score was 86.5 ± 8.7. Five (6.5%) patients developed minor complications. CONCLUSION: Partial division of puborectalis muscle combined with LIS is an effective technique in the management of anal hypertonia-associated anismus with satisfactory results and low incidence of complications.

Laparoscopic Ventral Mesh Rectopexy Versus Transvaginal Posterior Colporrhaphy in Management of Anterior Rectocele.

BACKGROUND: Management of rectocele is challenging. Treatment usually starts with conservative measures and may involve surgical intervention in non-responding patients. We compared the outcomes of transvaginal posterior colporrhaphy (PC) and laparoscopic ventral mesh rectopexy (LVMR) in treatment of anterior rectocele. METHODS: Patients with anterior rectocele who underwent PC or LVMR were functionally assessed using Cleveland Clinic Constipation Score (CCCS) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Pelvic Organ Prolapse Quantification System (POP-Q) was used for clinical assessment, defecography for anatomic assessment, and manometry for physiologic assessment. In addition, quality of life was assessed. RESULTS: A total of 231 female patients with a mean age of 39 years were included to the study. One hundred fifty-nine underwent PC and 72 underwent LVMR. The LVMR group showed significantly a better functional outcome as compared with the PC group (p < 0.0001). The mean of CCCS at 1 year after LVMR was 6 ± 2.3 vs 9.2 ± 1.2 after PC. The mean of PISQ-12 at 1 year after LVMR was 39.3 ± 2.8 vs 35.8 ± 2.2 after PC. LVMR showed better anatomic correction by defecography, had significantly higher quality of life scores, and had a longer operative time as compared with PC, yet with comparable incidence of complications. CONCLUSION: PC and LVMR are both effective treatment options for treatment of rectocele. LVMR was associated with better anatomic correction and greater improvement in constipation, sexual symptoms, and quality of life compared with PC. Although LVMR had a longer operation time than PC, the complication rate of the two procedures was comparable.

Impact of Pyloric Injection of Magnesium Sulfate-Lidocaine Mixture on Postoperative Nausea and Vomiting After Laparoscopic Sleeve Gastrectomy: a Randomized-Controlled Trial.

BACKGROUND: One of the most common adverse effects of laparoscopic sleeve gastrectomy (LSG) is postoperative nausea and vomiting (PONV). The present study aimed to assess the impact of local injection of a mixture of magnesium sulfate and lidocaine into the pylorus on gastric intraluminal pressure (ILP) and PONV after LSG. METHODS: Patients with morbid obesity who underwent LSG were randomly allocated to one of two equal groups: treatment group (pyloric injection of a mixture of magnesium sulfate and lidocaine) and control group (pyloric injection of normal saline). PONV and antiemetic requirements were recorded at 6 and 24 h postoperatively. RESULTS: Seventy patients (63 female) with a mean age of 34.6 ± 9.9 years were included. The mean preoperative and postoperative gastric ILP was comparable in the two groups. The pyloric injection of magnesium sulfate-lidocaine mixture resulted in 31% reduction in the mean gastric ILP (19.4 ± 4.7 mmHg before injection to 13.4 ± 4.1 mmHg after injection, p < 0.0001). Pyloric injection of saline did not result in significant change in ILP (19.9 ± 4.9 vs 20.3 ± 5.1 mmHg). Of the treatment group patients, 17.1% had significant PONV at 6 h compared to 91.4% of control group patients (p < 0.0001). At 24 h, none of the treatment group patients had significant PONV versus 40% of the control group patients (p < 0.0001). CONCLUSION: Pyloric injection of magnesium sulfate-lidocaine mixture during LSG resulted in lower incidence of PONV and less use of antiemetic medications in the first 24 h after LSG without being associated with higher complication rate.

Bariatric Bypass Surgery to Resolve Complicated Childhood Morbid Obesity: Case Report Study.

Children obesity has become one of the most important public health problems in many countries worldwide. Although the awareness of childhood obesity as a modifiable health risk is high, but many societies do not prioritize this issue as a health care problem, which may lead to comorbidities and even premature death. Despite the rising interest in bariatric surgery for children, only laparoscopic sleeve gastrectomy (LSG) is being considered in resolving childhood obesity who failed other dietary or drug therapies; however many of LSG procedures failed to reduce the weight in children or resulted in complications postsurgery.Here, we present a novel bariatric procedure to clue out a female child 13 years old presented with Legg-Calvé-Perthes disease-associated morbid obesity. The surgical bariatric technique applied both fundal resection and surgical bypass in pediatric obesity using the Elbanna novel bariatric technique.Bariatric surgical bypass may be considered in complicated-childhood cases who failed all other options.
