Side-specific factors for intraoperative hemodynamic instability in laparoscopic adrenalectomy for pheochromocytoma: a comparative study.

BACKGROUND: Adrenalectomy for pheochromocytoma (PHEO) is challenging because of the high risk of intraoperative hemodynamic instability (HDI). This study aimed to compare the incidence and risk factors of intraoperative HDI between laparoscopic left adrenalectomy (LLA) and laparoscopic right adrenalectomy (LRA). METHODS: We retrospectively analyzed two hundred and seventy-one patients aged > 18 years with unilateral benign PHEO of any size who underwent transperitoneal laparoscopic adrenalectomy at our hospitals between September 2016 and September 2023. Patients were divided into LRA (N = 122) and LLA (N = 149) groups. Univariate and multivariate logistic regression analyses were used to predict intraoperative HDI. In multivariate analysis for the prediction of HDI, right-sided PHEO, PHEO size, preoperative comorbidities, and preoperative systolic blood pressure were included. RESULTS: Intraoperative HDI was significantly higher in the LRA group than in the LLA (27% vs. 9.4%, p < 0.001). In the multivariate regression analysis, right-sided tumours showed a higher risk of intraoperative HDI (odds ratio [OR] 5.625, 95% confidence interval [CI], 1.147-27.577, p = 0.033). The tumor size (OR 11.019, 95% CI 3.996-30.38, p < 0.001), presence of preoperative comorbidities [diabetes mellitus, hypertension, and coronary heart disease] (OR 7.918, 95% CI 1.323-47.412, p = 0.023), and preoperative systolic blood pressure (OR 1.265, 95% CI 1.07-1.495, p = 0.006) were associated with a higher risk of HDI in both LRA and LLA, with no superiority of one side over the other. CONCLUSION: LRA was associated with a significantly higher intraoperative HDI than LLA. Right-sided PHEO was a risk factor for intraoperative HDI.

International survey on complications of religious fasting after metabolic and bariatric surgery.

Religious fasting in Ramadan the 9th month of the lunar year is one of five pillars in Islam and is practiced for a full month every year. There may be risks with fasting in patients with a history of metabolic/bariatric surgery (MBS). There is little published evidence on the possible complications during fasting and needs stronger recommendations and guidance to minimize them. An international survey was sent to surgeons to study the types of complications occurring during religious fasting in patients with history of MBS to evaluate the risk factors to manage and prepare more evidence-based recommendations. In total, 21 centers from 11 countries participated in this survey and reported a total of 132 patients with complications occurring during religious fasting after MBS. The mean age of patients with complications was 36.65 ± 3.48 years and mean BMI was 43.12 ± 6.86 kg/m2. Mean timing of complication occurring during fasting after MBS was 14.18 months. The most common complications were upper GI (gastrointestinal) symptoms including [gastroesophageal reflux disease (GERD), abdominal pain, and dyspepsia], marginal ulcers and dumping syndrome in 24% (32/132), 8.3% (11/132) and 23% (31/132) patients respectively. Surgical management was necessary in 4.5% of patients presenting with complications (6/132) patients due to perforated marginal or peptic ulcer in Single Anastomosis Duodenoileostomy with Sleeve gastrectomy (SADI-S), one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG), obstruction at Jejunojenostomy after Roux-en-Y gastric bypass (RYGB) (1/6) and acute cholecystitis (1/6). Patients after MBS should be advised about the risks while fasting including abdominal pain, dehydration, and peptic ulcer disease exacerbation, and a thorough review of their medications is warranted to minimize complications.

Biliary fistula and late recurrence of liver hydatid cyst: Role of cysto-biliary communication: A prospective multicenter study.

BACKGROUND: Hydatid cyst disease (HCD) is common in certain locations. Surgery is associated with postoperative biliary fistula (POBF) and recurrence. The primary aim of this study was to identify whether occult cysto-biliary communication (CBC) can predict recurrent HCD. The secondary aim was to assess the role of cystic fluid bilirubin and alkaline phosphatase (ALP) levels in predicting POBF and recurrent HCD. AIM: To identify whether occult CBC can predict recurrent HCD. The secondary aim was to assess the role of cystic fluid bilirubin and ALP levels in predicting POBF and recurrent HCD. METHODS: From September 2010 to September 2016, a prospective multicenter study was undertaken involving 244 patients with solitary primary superficial stage cystic echinococcosis 2 and cystic echinococcosis 3b HCD who underwent laparoscopic partial cystectomy with omentoplasty. Univariable logistic regression analysis assessed independent factors determining biliary complications and recurrence. RESULTS: There was a highly statistically significant association (P ≤ 0.001) between cystic fluid biochemical indices and the development of biliary complications (of 16 patients with POBF, 15 patients had high cyst fluid bilirubin and ALP levels), where patients with high bilirubin-ALP levels were 3405 times more likely to have biliary complications. There was a highly statistically significant association (P ≤ 0.001) between biliary complications, biochemical indices, and the occurrence of recurrent HCD (of 30 patients with recurrent HCD, 15 patients had high cyst fluid bilirubin and ALP; all 16 patients who had POBF later developed recurrent HCD), where patients who developed biliary complications and high bilirubin-ALP were 244.6 and 214 times more likely to have recurrent hydatid cysts, respectively. CONCLUSION: Occult CBC can predict recurrent HCD. Elevated cyst fluid bilirubin and ALP levels predicted POBF and recurrent HCD.

Intraoperative endomanometric laparoscopic Nissen fundoplication improves postoperative outcomes in large sliding hiatus hernias with severe gastroesophageal reflux disease: a retrospective cohort study.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) is the gold standard surgical intervention for gastroesophageal reflux disease (GERD). LNF can be followed by recurrent symptoms or complications affecting patient satisfaction. The aim of this study is to assess the value of the intraoperative endomanometric evaluation of esophagogastric competence and pressure combined with LNF in patients with large sliding hiatus hernia (>5 cm) with severe GERD (DeMeester score >100). MATERIALS AND METHODS: This is a retrospective, multicenter cohort study. Baseline characteristics, postoperative dysphagia and gas bloat syndrome, recurrent symptoms, and satisfaction were collected from a prospectively maintained database. Outcomes analyzed included recurrent reflux symptoms, postoperative side effects, and satisfaction with surgery. RESULTS: Three hundred sixty patients were stratified into endomanometric LNF (180 patients, LNF+) and LNF alone (180 patients, LNF). Recurrent heartburn (3.9 vs. 8.3%) and recurrent regurgitation (2.2 vs. 5%) showed a lower incidence in the LNF+ group ( P =0.012). Postoperative score III recurrent heartburn and score III regurgitations occurred in 0 vs. 3.3% and 0 vs. 2.8% cases in the LNF+ and LNF groups, respectively ( P =0.005). Postoperative persistent dysphagia and gas bloat syndrome occurred in 1.75 vs. 5.6% and 0 vs. 3.9% of patients ( P =0.001). Score III postoperative persistent dysphagia was 0 vs. 2.8% in the two groups ( P =0.007). There was no redo surgery for dysphagia after LNF+. Patient satisfaction at the end of the study was 93.3 vs. 86.7% in both cohorts, respectively ( P =0.05). CONCLUSIONS: Intraoperative high-resolution manometry and endoscopic were feasible in all patients, and the outcomes were favorable from an effectiveness and safety standpoint.

A prospective multicentre study evaluating the outcomes of the abdominal wall dehiscence repair using posterior component separation with transversus abdominis muscle release reinforced by a retro-muscular mesh: filling a step.

BACKGROUND: This study aimed to evaluate the results of posterior component separation (CS) and transversus abdominis muscle release (TAR) with retro-muscular mesh reinforcement in patients with primary abdominal wall dehiscence (AWD). The secondary aims were to detect the incidence of postoperative surgical site occurrence and risk factors of incisional hernia (IH) development following AWD repair with posterior CS with TAR reinforced by retromuscular mesh. METHODS: Between June 2014 and April 2018, 202 patients with grade IA primary AWD (Björck's first classification) following midline laparotomies were treated using posterior CS with TAR release reinforced by a retro-muscular mesh in a prospective multicenter cohort study. RESULTS: The mean age was 42 ± 10 years, with female predominance (59.9%). The mean time from index surgery (midline laparotomy) to primary AWD was 7 ± 3 days. The mean vertical length of primary AWD was 16 ± 2 cm. The median time from primary AWD occurrence to posterior CS + TAR surgery was 3 ± 1 days. The mean operative time of posterior CS + TAR was 95 ± 12 min. No recurrent AWD occurred. Surgical site infections (SSI), seroma, hematoma, IH, and infected mesh occurred in 7.9%, 12.4%, 2%, 8.9%, and 3%, respectively. Mortality was reported in 2.5%. Old age, male gender, smoking, albumin level < 3.5 gm%, time from AWD to posterior CS + TAR surgery, SSI, ileus, and infected mesh were significantly higher in IH. IH rate was 0.5% and 8.9% at two and three years, respectively. In multivariate logistic regression analyses, the predictors of IH were time from AWD till posterior CS + TAR surgical intervention, ileus, SSI, and infected mesh. CONCLUSION: Posterior CS with TAR reinforced by retro-muscular mesh insertion resulted in no AWD recurrence, low IH rates, and low mortality of 2.5%. Trial registration Clinical trial: NCT05278117.

Hepatobiliary manifestations following two-stages elective laparoscopic restorative proctocolectomy for patients with ulcerative colitis: A prospective observational study.

BACKGROUND: Hepatobiliary manifestations occur in ulcerative colitis (UC) patients. The effect of laparoscopic restorative proctocolectomy (LRP) with ileal pouch anal anastomosis (IPAA) on hepatobiliary manifestations is debated. AIM: To evaluate hepatobiliary changes after two-stages elective laparoscopic restorative proctocolectomy for patients with UC. METHODS: Between June 2013 and June 2018, 167 patients with hepatobiliary symptoms underwent two-stage elective LRP for UC in a prospective observational study. Patients with UC and having at least one hepatobiliary manifestation who underwent LRP with IPAA were included in the study. The patients were followed up for four years to assess the outcomes of hepatobiliary manifestations. RESULTS: The patients' mean age was 36 ± 8 years, and males predominated (67.1%). The most common hepatobiliary diagnostic method was liver biopsy (85.6%), followed by Magnetic resonance cholangiopancreatography (63.5%), Antineutrophil cytoplasmic antibodies (62.5%), abdominal ultrasonography (35.9%), and Endoscopic retrograde cholangiopancreatography (6%). The most common hepatobiliary symptom was Primary sclerosing cholangitis (PSC) (62.3%), followed by fatty liver (16.8%) and gallbladder stone (10.2%). 66.4% of patients showed a stable course after surgery. Progressive or regressive courses occurred in 16.8% of each. Mortality was 6%, and recurrence or progression of symptoms required surgery for 15%. Most PSC patients (87.5%) had a stable course, and only 12.5% became worse. Two-thirds (64.3%) of fatty liver patients showed a regressive course, while one-third (35.7%) showed a stable course. Survival rates were 98.8%, 97%, 95.8%, and 94% at 12 mo, 24 mo, 36 mo, and at the end of the follow-up. CONCLUSION: In patients with UC who had LRP, there is a positive impact on hepatobiliary disease. It caused an improvement in PSC and fatty liver disease. The most prevalent unchanged course was PSC, while the most common improvement was fatty liver disease.

Outcomes of side-to-end versus end-to-end colorectal anastomosis in nonemergent sigmoid and rectal cancers: a randomized controlled clinical trial.

PURPOSE: The outcomes of open colorectal anastomosis of side-to-end versus end-to-end in nonemergent sigmoid and rectal cancer surgery in adults were compared. METHODS: A randomized controlled trial on individuals with sigmoid and rectal cancers was conducted between September 2016 and September 2018. RESULTS: The mean age was 62.58±12.3 years in the side-to-end anastomotic (SEA) group and 61.03±13.98 years in the end-to-end anastomotic (EEA) group. Except for the operative time, intraoperative data revealed no significant differences between the studied groups, and the SEA group revealed that the mean anastomotic time was significantly shorter. Perioperative blood loss, length of stay, reoperation, inpatient death, infection, and bleeding were significantly associated with leakage. There is a statistically significant change regarding the range of bowel frequency in the EEA group only (P=0.04). There is a statistically significant difference regarding incontinence for flatus in the SEA group only (P≤0.001). A statistically significant change in both groups regards incontinence for liquid stools (P≤0.001) and clustering of stools (P≤0.001 and P=0.043). The quality of life in the SEA group significantly dropped at 6 months and then returned to baseline as regards to physical well-being (PWB), functional well-being (FWB), and colorectal cancer symptoms (CCS) with no difference as regards SWB and EWB, while in the EEA group, the exact change happened only as regard PWB and FWB, but SWB and CCS percentage did not return to baseline. CONCLUSION: The SEA group offers a safe alternative approach to the EEA group.

Sleeve Gastrectomy and Cholecystectomy are Safe in Obese Patients with Asymptomatic Cholelithiasis. A Multicenter Randomized Trial.

BACKGROUND: Obesity is a severe health problem. Gallstones may symptomatize after sleeve gastrectomy (SG). Concomitant laparoscopic cholecystectomy (LC) with SG is controversial. The effects of SG and LC versus delayed LC following SG in obese patients with asymptomatic gallbladder stones were evaluated. METHODS: A randomized trial of 222 morbidly obese patients with gallbladder stones divided them into two equal groups: SG + LC and SG-only. This multicenter study conducted from January 2016 to January 2019. RESULTS: Except for operative time and postoperative hospital stay, there was no statistically significant difference between LSG + LC group and SG group (P < 0.001). In SG + LC group, LC added 40.7 min to SG, three patients (3%) required conversion, early postoperative complications occurred in 9 cases (9/111, 9%), three cases required re-intervention (3%). In SG group, the complicated cases required LC were 61 cases (61/111, 55%). Acute cholecystitis (26/61, 42.7%) was the most common gallstone symptoms. Most complicated cases occurred in the first-year follow-up (52/61, 85%). In the delayed LC group (61 patients), operative time was 50.13 ± 1.99 min, open conversion occurred in 2 cases (2/61, 3.2%), early postoperative complications occurred in four patients (4/61, 6.4%) and postoperative re-intervention were due to bile leaks and cystic artery bleeding (2/61, 3.2%). CONCLUSIONS: SG with LC prolongs the operative time and hospital stay, but the perioperative complications are the same as delayed LC; LC with SG minimizes the need for a second surgery. Concomitant LC with SG is safe.

Recurrent appendicitis following successful drainage of appendicular abscess in adult without interval appendectomy during COVID-19. Prospective cohort study.

BACKGROUND: COVID-19 infection is a global pandemic that affected routine health services and made patients fear to consult for medical health problems, even acute abdominal pain. Subsequently, the incidence of complicated appendicitis increased during the Covid-19 pandemic. This study aimed to evaluate recurrent appendicitis after successful drainage of appendicular abscess during COVID-19. MATERIAL AND METHODS: A prospective cohort study conducted in the surgical emergency units of our Universities' Hospitals between March 15, 2020 to August 15, 2020 including patients who were admitted with the diagnosis of an appendicular abscess and who underwent open or radiological drainage. Main outcomes included incidence, severity, and risk factors of recurrent appendicitis in patients without interval appendectomy. RESULTS: A total of 316 patients were included for analysis. The mean age of the patients was 37 years (SD ± 13). About two-thirds of patients were males (60.1%). More than one-third (39.6%) had co-morbidities; type 2 diabetes mellitus (T2DM) (22.5%) and hypertension (17.1%) were the most frequent. Approximately one quarter (25.6%) had confirmed COVID 19 infection. About one-third of the patients (30.4%) had recurrent appendicitis. More than half of them (56.3%) showed recurrence after three months, and 43.8% of patients showed recurrence in the first three months. The most frequent grade was grade I (63.5%). Most patients (77.1%) underwent open surgery. Age, T2DM, hypertension, COVID-19 infection and abscess size >3 cm were significantly risking predictors for recurrent appendicitis. CONCLUSIONS: Interval appendectomy is suggested to prevent 56.3% of recurrent appendicitis that occurs after 3 months. We recommend performing interval appendectomy in older age, people with diabetes, COVID-19 infected, and abscesses more than 3 cm in diameter. RESEARCH QUESTION: Is interval appendectomy preventing a high incidence of recurrent appendicitis after successful drainage of appendicular abscess during COVID-19 pandemic?

Changing the innate consensus about mesh fixation in trans-abdominal preperitoneal laparoscopic inguinal hernioplasty in adults: Short and long term outcome. Randomized controlled clinical trial.

INTRODUCTION: Inguinal hernioplasty is the standard treatment for inguinal hernia in adults. Mesh fixation was used to keep mesh in place for which various mesh fixation techniques have been used in laparoscopic inguinal hernia repair in adults, but their effectiveness has remained inconclusive. AIM OF THE WORK: to evaluate non fixation method of mesh laparoscopic inguinal hernioplasty as safe and effective as regard short and long term outcomes. PATIENTS AND METHODS: Over the period from July 2013 to July 2018, 798 patients with oblique inguinal hernias undergoing Trans abdominal preperitoneal technique (TAPP) were randomized into 3 groups: Group A; mesh non fixation 266 patients. Group B; tacker mesh fixation 266 patients Group C: Cyanoacrylic tissue glues (Histoacryl) mesh fixation 266 patients. Clinical effects were assessed by the following variables: intraoperative data, postoperative outcome as regard recurrence rate, postoperative pain [on visual analogue score (VAS)], analgesic consumption, operation time, hospital stay, and patient costs. Follow up was 18 months. RESULTS: There was no statistical difference between groups (A) and Group (C) regarding operative time, postoperative complications, and length of hospital stay and risk of chronic groin pain, postoperative pain score. In Group (B): the postoperative pain and complications were higher. There were 5 cases of hernia recurrence in all groups, but no significant differences among the three groups. CONCLUSION: Tacker Mesh fixation increased the risk of chronic groin pain. Pain score was higher with tacker mesh fixation. Laparoscopic TAPP inguinal hernia repair without tacker mesh fixation was safe and feasible with no significant increase in recurrence rates. Furthermore, mesh fixation with tacker procedure increased the risk of postoperative complications and patient costs. All ethical approval was given by our Faculty of Medicine medical ethical committee.

Modified perineal linear stapler resection for external rectal prolapse.

BACKGROUND: rectal prolapse can cause bleeding and fecal incontinence that affects the life quality of patients. The treatment of external rectal prolapse is surgical. There are many procedures (abdominal or perineal) that can be used depending on the severity of the condition and patient tolerability for operation. In this study, a simple safe procedure is used for the treatment of the rectal prolapse in old, fragile and comorbid patients who cannot withstand the major surgeries and the risk of long-duration anesthesia. METHODS: from December 2016 to July 2019, 36 elderly comorbid patients with rectal prolapse were involved in this study which is performed in the GIT surgery unit of Zagazig University Hospital. A modified linear stapler resection technique is used for the rectal prolapse. Postoperative follow up was done for one year to evaluate the functional outcome, operative time, hospital stay duration and complications. RESULT: this study was conducted on 36 patients; The median age was 75 years (range 48-95). The postoperative complication rate was 11.1%. The median operative time was 25 min and 4 days for the hospital stay. Fecal incontinence improved in more than 90% of patients and constipation disappeared in 66% of total constipating patients. CONCLUSION: The modified perineal linear stapler resection for external rectal prolapse is a good, easy, rapid treatment for elderly comorbid patients with good functional outcomes.
