Effectiveness of preserved vagal nerve in totally laparoscopy radical distal gastrectomy: a matched-paired cohort analysis.

BACKGROUND: The aim of this retrospective matched-paired cohort study was to clarify the effectiveness of preserving the vagus nerve in totally laparoscopic radical distal gastrectomy (TLDG). METHODS: One hundred eighty-three patients with gastric cancer who underwent TLDG between February 2020 and March 2022 were included and followed up. Sixty-one patients with preservation of the vagal nerve (VPG) in the same period were matched (1:2) to conventional sacrificed (CG) cases for demographics, tumor characteristics, and tumor node metastasis stage. The evaluated variables included intraoperative and postoperative indices, symptoms, nutritional status, and gallstone formation at 1 year after gastrectomy between the two groups. RESULTS: Although the operation time was significantly increased in the VPG compared with the CG (198.0 ± 35.2 vs. 176.2 ± 35.2 min, P < 0.001), the mean time of gas passage in the VPG was significantly lower than that in the CG (68.1 ± 21.7 h vs. 75.4 ± 22.6 h, P = 0.038). The overall postoperative complication rate was similar between the two groups (P = 0.794). There was no statistically significant difference between the two groups hospital stay, total number of harvested lymph nodes, and mean number of examined lymph nodes at each station. During follow-up, the morbidity of gallstones or cholecystitis (8.2% vs. 20.5%, P = 0.036), chronic diarrhea (3.3% vs. 14.8%, P = 0.022), and constipation (4.9% vs. 16.4%, P = 0.032) were significantly lower in the VPG than in the CG in this study. Moreover, injury to the vagus nerve was found to be an independent risk factor for gallstone formation or cholecystitis and chronic diarrhea in univariate analysis and multivariate analysis. CONCLUSION: The vagus nerve plays an imperative role in gastrointestinal motility, and hepatic and celiac branch preservation mainly exerts efficacy and safety in patients who undergo TLDG.

Colchicine usage for prevention of post atrial fibrillation ablation pericarditis in patients undergoing high-power short-duration ablation.

INTRODUCTION: Radiofrequency ablation (RFA) for atrial fibrillation (AF) has been associated with variable incidence (0.88%-10%) of pericarditis manifested as chest pain, possibly more prevalent with the advent of high-power short-duration (HPSD) ablation. This has led to the widespread use of colchicine in preventative protocols for postablation pericarditis. However, the efficacy of preventative colchicine has not been validated yet. OBJECTIVE: To evaluate the efficacy of a routine postoperative colchicine regimen (0.6 mg twice a day for 14 days post-AF ablation) for prevention of postablation pericarditis in patients undergoing HPSD ablation. METHOD: We retrospectively evaluated consecutive single-operator HPSD AF ablation procedures at our institution from June 2019 to July 2022. A colchicine protocol was introduced in June 2021 for the prevention of postablation pericarditis. All ablations were performed with 50 watts. Patients were divided into colchicine and noncolchicine groups. We recorded incidence of postablation chest pain, emergency room (ER) visit for chest pain, pericardial effusion, pericardiocentesis, any ER visit, hospitalization, AF recurrence, and cardioversion for AF within the first 30 days following ablation. We also recorded colchicine-related side effects and medication compliance. RESULTS: Two hundred and ninety-four consecutive HPSD AF ablation patients were screened for the study. After implementing the prespecified exclusion criteria, a total of 205 patients were included in the final analysis, yielding 101 patients in the colchicine group and 104 patients in the noncolchicine group. Both groups were well-matched for demographic and procedural parameters. There was no significant difference in postablation chest pain (9.9% vs. 8.6%, p = .7), pericardial effusion (2.9% vs. 0.9%, p = .1), ER visits (11.9% vs. 12.5%, p = .2), 30-day hospitalization for AF recurrence (0.9% vs. 0.96%, p = .3), and 30-day need for cardioversion for AF (3.9% vs. 5.7%, p = .2). Fifteen (15) patients had severe colchicine-related diarrhea, out of which 12 discontinued it prematurely. There were no major procedural complications in either group. CONCLUSION: In this single-operator retrospective analysis, prophylactic colchicine was not associated with significant reduction in the incidence of postablation chest pain, pericarditis, 30 day hospitalization, ER visits, or AF recurrence or need of cardioversion within first 30 days after HPSD ablation for AF. However, its usage was associated with significant diarrhea. This study concludes no additional advantage of prophylactic use of colchicine after HPSD AF ablation.

[Study on the efficacy and complications of patients undergoing radical surgery and radical radiotherapy for localized prostate cancer].

OBJECTIVE: To compare the efficacy and complications of radical surgery (RP) and radical radiotherapy (RRT). METHODS: The clinical data of patients diagnosed with localized prostate cancer in General Hospital of Eastern Theater Command with RP and RRT from January 2015 to December 2019, Observed and recorded patient preoperative and postoperative PSA levels, biochemical Relapse-free Survival and clinical Relapse-free Survival,and the occurrence of hematuria, urinary incontinence, erectile dysfunction, ankylurethria, diarrhea, hemoproctia and radiocystitis. RESULTS: A total of 150 patients with localized prostate cancer were included in this study, including 105 patients with RP and 45 patients undergoing RRT. There was no significant difference between the complication rates of hematuria, urinary incontinence, erectile dysfunction and ankylurethria(P>0.05).Patients in the RRT group had higher rates of diarrhea(20.00% vs 2.86%), hemoproctia(15.56% vs 1.90%) and radiocystitis(13.33% vs 0%) than those in the RP group, with significant differences (P<0.05). The 5-year bRFS was lower than that in the RP group (95.1% vs 90.7%), with no statistical significance (P=0.832); the 5-year cRFS in the RP group was lower than that in the RRT group (91.2% vs 89.6%), with no significant difference (P=0.971). CONCLUSION: The incidence of diarrhea, hemoproctia and radiocystitis was lower in the RP group than in the RRT group, and the recurrence-free survival was not significantly different between the two groups.

Partial External Biliary Diversion for Severe Diarrhea After Liver Transplant in Patients with Progressive Familial Intrahepatic Cholestasis Type 1.

Progressive familial intrahepatic cholestasis is a heterogeneous group of autosomal recessive disorders, and liver transplant is the only curative treatment. A biliary diversion operation for disruption of enterohepatic circulation in patients with progressive familial intrahepatic cholestasis type 1 without cirrhosis is another option. We present a pediatric patient with progressive familial intrahepatic cholestasis type 1 who underwent liver transplant due to end-stage liver disease. After transplant, diarrhea and growth retardation complications resolved after partial external biliary diversion surgery.

Chronic abdominal pain and diarrhea.

Pigmented macules on the patient's oral mucosa provided an important clue to the diagnosis.

Young-Onset Ischemic Colitis: A Condition of Elusive Etiology Frequently Associated With Immune Dysregulation.

Ischemic colitis (IC) associates with older age, hypertension, and heart disease, among others. Young-onset IC is rare. We aimed to delineate clinical characteristics of young patients (<40 years) with IC. Cases from 1984 to 2017 were re-reviewed. Of the 60 cases available, 52% (n = 31) had histologic features of IC. Fifty-five percent were female with a mean age of 32 (range = 14-40) years. Fifty-eight percent (n = 18) were resections. The most common presentations were diarrhea and abdominal pain. Three teenagers had IC associated with prior surgery, volvulus, and constipation. In the 21- to 40-year group, 43% (n = 12) lacked clinical associations. A second subset (n = 6, 21%) had histories of immune dysregulation (lupus, dermatomyositis, vasculitis) and poorly controlled HIV/AIDS (n = 5, 18%). Smoking and cocaine were endorsed by 1 and 2 patients, respectively. One patient had premature atherosclerosis while another had HMG Co-A lyase deficiency. Vasculitis was identified in 22% of the resections and in none of the biopsies. Nineteen percent of patients died (n = 6) from complications of IC, all treated surgically, including 1 patient previously misdiagnosed as ulcerative colitis; 2 patients died of unrelated causes. While rare before 20 years of age, IC in teenagers relates to mechanical issues and is rare in children. Associations in young adults include immune dysregulation, cocaine and cigarette use, and premature atherosclerosis. Our retrospective cohort had a surgical mortality rate within the range reported by others, highlighting the importance of accurate diagnosis in young individuals.

Bowel Reconstruction to Treat Chronic Diarrhea and Hypoproteinemia Following Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy: a Single-Site Experience.

BACKGROUND: Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of the biliopancreatic diversion with duodenal switch (BPD-DS) surgery. A concern with SADI-S is chronic diarrhea and hypoproteinemia. Common channel lengthening (CCL) is a surgical procedure to increase absorption in the small intestine to decrease diarrhea. OBJECTIVES: The aim of this study was to assess the occurrence and treatment of hypoproteinemia and chronic diarrhea with CCL following SADI-S surgery. SETTING: Private practice in the USA. METHODS: Patients were included if they underwent SADI-S from September 2013 to March 2018 and following surgery underwent CCL. RESULTS: Average operating time for laparoscopic CCL is 56.5 ± 4.6 min. The average bowel movements for the eight patients before laparoscopic CCL were 9.1 ± 4.7 a day. After the surgery, the bowel movements were reduced to 2.6 ± 0.4 a day. This difference was found to be statistically significantly different (p = .002). The two patients experiencing hypoproteinemia improved protein levels following CCL. CONCLUSION: CCL is an effective way to treat symptomatic chronic diarrhea after SADI-S when conservative treatments have failed.

Laparoscopic revisional surgery for an unusual complication of Roux-en-Y gastric bypass.

With the worldwide epidemic of obesity, there has been an increase in the numbers of primary and revisional procedures of bariatric surgery such as the Roux-en-Y gastric bypass (RYGBP). Nevertheless, this type of surgery is not exempt from complications. An excessive length of non-functional Roux limb proximal to the jejunojejunostomy can cause abnormal upper gastrointestinal symptoms after laparoscopic RYGBP. We present the case of a female patient who presented these unspecific abdominal symptoms after laparoscopic RYGBP who underwent laparoscopic resection in order to reduce the length of the dilated blind loop responsible for the symptoms.

[A man with abdominal pain, diarrhoea and rectal bleeding]. / Een man met buikpijn, diarree en rectaal bloedverlies.

A 49-year-old man came to the emergency room with abdominal pain, vomiting, diarrhoea and rectal bleeding. Both colonoscopy and CT of the abdomen showed cecocolic intussusception caused by an appendiceal mucocele. An ileocecal resection was performed via a laparoscopic approach and microscopy of the tissue showed a low-grade mucinous neoplasm.

Conversion of standard Roux-en-Y gastric bypass to distal bypass for weight loss failure and metabolic syndrome: 3-year follow-up and evolution of technique to reduce nutritional complications.

BACKGROUND: Standard proximal Roux-en-Y gastric bypass (RYGB) fails to achieve long-term weight maintenance and/or control of metabolic syndrome in up to 35% of patients. OBJECTIVES: To improve the performance of the standard proximal gastric bypass by increasing the biliopancreatic limb length at the expense of the common channel. SETTINGS: Academic-affiliated private practice. METHODS: A retrospective review of all patients who underwent conversion to distal RYGB from 2010 to 2016 was performed. RYGB was modified by dividing the Roux limb at the jejunojejunostomy and transposing it distally to create a shortened total alimentary limb length (TALL) of 250 to 300 cm in the initial 11 patients. Of these, 7 developed protein calorie malnutrition and diarrhea requiring a second procedure to lengthen the common channel an additional 100 to 150 cm (TALL 400-450 cm), leading to resolution of all symptoms. The subsequent 85 patients were converted to distal RYGB with TALL 400 to 450 in a single-stage operation. RESULTS: Ninety-six RYGB patients underwent conversion to distal RYGB. The mean body mass index and mean excess weight loss at the time of distalization was 40.6 kg/m2 and 33.6%. At 1, 2, and 3 years after distalization, the mean body mass index was reduced to 34.4, 33.1, and 32.2 kg/m2, respectively, and excess weight loss improved to 41.9%, 53.7%, and 65.7%, respectively. Diabetes resolved in 66.7%, hypertension resolved in 28.6%, hyperlipidemia resolved in 40%, and sleep apnea resolved in 50% at 1 year. The 30-day complication rate and reoperation rates were 6.3% and 5.2%; an additional 7.3% (7/96) required reoperation for limb lengthening. Hypoalbuminemia developed in 21% at 3 years, but no increase in iron deficiency was observed. Calcium metabolism was affected by the distalization procedure to a greater degree as 21% of patients had low corrected calcium levels, 77% were deficient in vitamin D, and parathyroid hormone levels were above normal in 64% at 3 years. CONCLUSION: Revision of proximal RYGB to distal RYGB results in substantial improvement in weight loss and resolution of co-morbidities at 3 years. Diarrhea and protein calorie malnutrition were seen frequently in patients with TALL of 250 to 300 cm, whereas patients with TALL 400 to 450 cm demonstrated a lower incidence of nutritional issues, but the effect on calcium, parathyroid hormone, and the fat soluble vitamins A and D is still a major concern.

Surgical consequences in infants with delayed diagnosis of congenital chloride diarrhea.

Despite the usual typical presentation, congenital chloride diarrhea (CCD) poses multiple diagnostic challenges. It has an incidence of 1/5000 in Saudi Arabia. CCD can mimic intestinal obstruction and result in avoidable surgical interventions. Contributing factors are abdominal distension and the watery (urine-like) diarrhea that is often interpreted as delayed passage of meconium. Surgical interventions would unnecessarily increase the morbidity. Therefore, a high index of suspicion and educating neonatologists, general pediatricians, and pediatric surgeons regarding this diagnostic entity is essential. Here we describe five such cases.

Ileocaecal valve syndrome after surgery in adult patients: myth or reality?

AIM: The onset of symptoms after removal of the ileocaecal valve (ICV) may be perceived as an unwanted effect of surgery and induce patients to bring unnecessary litigation against surgeons. The aim of our study is to assess the real impact on the quality of life of patients whose ICV has been surgically removed, using three validated questionnaires. METHOD: In patients who had their ICV removed surgically, the Gastrointestinal Quality of life (GIQLI) questionnaire and those used by the European Organization for research and Treatment of Cancer (EORTC) were administered before and after surgery. The empirical rule effect size method was used to evaluate the clinical significance of the statistical data. RESULTS: We interviewed 225 patients. Data collected through the three questionnaires highlighted a trend towards postoperative improvement of the selected gastrointestinal symptoms compared with the baseline. The GIQLI questionnaire showed a statistically significant improvement in 'pain', 'nausea' and 'constipation' during the follow-up. Constipation appeared more frequently in patients older than 70 years compared with younger ones. The EORTC-QLQ-C30 questionnaire showed a significant correlation between diarrhoea and extended right colectomy at 3 months after surgery, which was not confirmed at 6 months. The EORTC QLQ-CR29 questionnaire showed a slight deterioration of 'leakage of stools from the anal opening' at 6 months after surgery, but this symptom was not deemed clinically significant. CONCLUSION: We found that bowel functions in most patients after surgical removal of the ICV were satisfactory. Providing patients with a comprehensive and exhaustive informed consent during preoperative consultations could promote patient trust and avoid misunderstandings.

Mycobacterium genavense-induced spindle cell pseudotumor in a pediatric hematopoietic stem cell transplant recipient: Case report and review of the literature.

We describe the first reported pediatric patient to our knowledge with a spindle cell pseudotumor caused by Mycobacterium genavense in a hematopoietic stem cell transplant recipient, and review the literature of such an entity in the transplant population.

Colonoscopy and Sigmoidoscopy are Equally Effective for the Diagnosis of Colonic Acute Graft-versus-Host Disease in Patients with Diarrhea after Allogeneic Stem Cell Transplantation: A Prospective Controlled Trial.

Colonic acute graft-versus-host disease (aGVHD) affects approximately 10% of patients who have undergone allogeneic stem cell transplantation (allo-SCT). Diarrhea is a major clinical sign but also a common post-transplantation symptom in these patients. Comprehensive histopathologic examination of the colon is therefore regarded as crucial to establish a diagnosis, but the colonic segment that should be targeted for a diagnostic biopsy remains a topic of debate. The primary objective of this study was to compare prospectively colonoscopy with sigmoidoscopy regarding their capabilities to provide a histopathologically proven diagnosis of colonic aGVHD. Thirty-seven allo-SCT patients with diarrhea all underwent a colonoscopy. All biopsies collected from the descending colon were regarded as also attainable by sigmoidoscopy, whereas biopsies collected in regions further up the colon (from the transverse and ascending colon) were regarded as acquirable exclusively by colonoscopy. Biopsies attainable by colonoscopy and sigmoidoscopy were positive for GVHD in 25 (68%) and 24 (65%) patients, respectively (95% confidence interval for difference of proportions, -.185 to .245; P = .978; z = .0271 by the z-test). Sigmoidoscopy is as effective as colonoscopy in establishing a diagnosis of colonic aGVHD in patients who have diarrhea after allo-SCT.

Single-balloon enteroscopy: a single-center experience of 48 procedures.

The aim of this study was to report the analysis of a single-center experience with single-balloon enteroscopy (SBE). A retrospective analysis of patients with small-bowel disorder who underwent SBE procedure from February 2011 to February 2013 was carried out. A total of 40 patients underwent 48 SBE procedures. Antegrade and retrograde approaches were used in 68.8 % and 31.2 % of subjects, respectively. The main indications were obscure gastrointestinal bleeding (n = 28), chronic diarrhea (n = 6), and chronic abdominal pain (n = 6). Average (SD) insertion length by antegrade approach was 150.6 (31.4) cm (range 90-210 cm) beyond the duodenojejunal flexure and by retrograde approach was 106.6 (29.4) cm (range 40-140 cm) proximal to the ileocecal junction. Average procedure time for antegrade approach was 46.3 (9.0) min (range 25-60 min) and for retrograde approach was 61.3 (12.8) min (range 45-90 min). Panendoscopy was not possible in any of the eight patients in whom antegrade and retrograde approaches were performed. Overall diagnostic yield was 55 % and therapeutic procedures were done in 20 % of patients. There were no significant complications. SBE is a safe and effective method to diagnose patients with small-bowel disease and provides a useful tool for intervention.

Small intestinal ganglioneuromatosis in a dog.

A 9-year-old female neutered collie-cross dog was presented with a 2-month history of persistent diarrhoea, weight loss and intermittent vomiting. Abdominal ultrasonography revealed one loop of jejunum with a markedly thickened and multifocally hyperechoic wall, without loss of wall layering. Laparotomies were performed for biopsy and resection of affected intestine. Histopathological examination revealed small intestinal ganglioneuromatosis (GN). The dog recovered well from surgery and the diarrhoea resolved. Eleven months later the dog has gained weight and remains asymptomatic. This is the first report of small intestinal GN affecting a mature dog, in which pathology was localized to the mucosal lamina propria and surgical treatment resulted in a successful outcome.

Quality of life and sexual function 1 year after laparoscopic rectosigmoid resection for endometriosis.

AIM: Endometriosis is relatively common condition in fertile women and may affect the alimentary tract. Laparoscopic rectosigmoid resection for endometriosis has been found to be both feasible and safe. The aim of the present study was to prospectively evaluate the quality of life and sexual function of patients who have undergone rectosigmoid resection for endometriosis. METHOD: All patients undergoing rectal or sigmoid resection for endometriosis in two specialist hospitals were prospectively recruited in the study. Details regarding demography, endometriosis-related symptoms, procedure and postoperative recovery were collected. One year after the operation patients were sent a postal questionnaire asking about endometriosis-related symptoms, quality of life and sexual functioning. The 15D Questionnaire and McCoy Female Sexuality Questionnaire were used for this purpose. RESULTS: A total of 26 patients responded to the 15D questionnaire. Endometriosis-related bowel symptoms decreased significantly after the operation. The responses showed improvements in the overall score and scores for five different dimensions (usual activities, P = 0.04; discomfort and symptoms, P < 0.001; distress, P < 0.001; vitality, P < 0.001; sexual activity, P < 0.001). Sexual satisfaction was greater 1 year after the operation (P = 0.01). Sexual problems and partner satisfaction scores had not changed significantly. CONCLUSION: Laparoscopic rectal and sigmoid resection for endometriosis significantly reduce endometriosis-related symptoms and improve quality of life and sexual well-being.
