Concomitant Sigmoid Diverticulitis and Periampullary Duodenal Diverticulitis Complicated by Lemmel Syndrome: A Case Report.

Diverticular disease is a major cause of hospitalizations, especially in the elderly. Although diverticulosis and its complications predominately affect the colon, the formation of diverticula in the small intestine, most commonly in the duodenum, is well characterized in the literature. Although small bowel diverticula are typically asymptomatic, and diagnosed incidentally, a complication of periampullary duodenal diverticulum is Lemmel syndrome. Lemmel syndrome is an extremely rare condition whereby periampullary duodenal diverticula, most commonly without diverticulitis, leads to obstruction of the common bile duct due to mass effect and associated complications including acute cholangitis and pancreatitis. Here, we present the first case, to our knowledge, of periampullary duodenal diverticulitis complicated by Lemmel syndrome with concomitant colonic diverticulitis with colovesical fistula. Our case and literature review emphasizes that Lemmel syndrome can present with or without suggestions of obstructive jaundice and can most often be managed conservatively if caught early, except in the setting of emergent complications.

Like a Rolling (Gall)Stone: Optimal Treatment of Gallstone Obstruction of the Sigmoid Colon.

BACKGROUND: Sigmoid gallstone ileus is a rare complication of cholelithiasis, accounting for 1-4% of all cases of large-bowel obstruction. This is a highly morbid, and often fatal, condition due to its challenging diagnosis and late presentation. CASE PRESENTATION: We report a case of a 90-year-old woman admitted to Emergency Department with abdominal pain and large-bowel obstruction due to a 6 cm gallstone lodged in a diverticulum of the proximal sigmoid colon as a consequence of a cholecysto-colonic fistula. Colonoscopy was deferred due to gallstone size carrying a high possibility of failure. The patient underwent urgent laparotomy with gallstone removal via colotomy. The cholecystocolonic fistula was left untreated. The post-operative course was uneventful; the patient was discharged on 6th post-operative day. CONCLUSION: A multidisciplinary discussion between endoscopists and surgeons is often needed to choose the best therapeutic option, especially in high-risk patients.

Intestinal pneumatosis as a manifestation of systemic sclerosis.

A 60-year-old female patient was admitted to the emergency room for a 7-day history of abdominal bloating, nausea, vomiting, constipation, and lack of flatus. She had been diagnosed with systemic sclerosis (SSc) 10 years ago and had been using methotrexate, sildenafil, and prednisone. She did not present any signs of instability, but physical examination showed malnourishment status and abdominal tenderness and distention. Plain abdominal radiography was suggestive of sigmoid volvulus, confirmed and successfully resolved after endoscopic decompression therapy. Eight months later, the patient developed a new episode of abdominal obstruction. Computed Tomography (CT) scan identified a distended sigmoid colon due to its torsion with gas areas within the bowel wall. This time, endoscopic decompression had failed to treat, so exploratory laparotomy was performed. Colonic distention and sigmoid volvulus were identified during the procedure, after which sigmoidectomy followed by primary anastomosis was performed. Neither perforation nor masses were found. Furthermore, the anatomopathological study was inconsistent with vascular, inflammatory, or neoplastic diseases.

Recurrence-Preventive Role of Flatus Tubes Following Endoscopic Decompression in Sigmoid Volvulus.

BACKGROUND: Sigmoid volvulus may recur following endoscopic decompression. Flatus tubes are traditionally used to prevent an early recurrence. This study aims to evaluate the recurrence-preventive role of the flatus tubes in sigmoid volvulus. METHODS: Sigmoid volvulus recurrence was retrospectively analyzed in prospectively collected clinical data of endoscopically decompressed 60 patients, in whom no tube, rectal tube, or sigmoidal tube was used. RESULTS: Mean pain/discomfort scores were higher in rectal and sigmoidal tube groups than that of no tube group (1.2 ± 0.4, 4.2 ± 0.9, and 3.5 ± 0.9, respectively, P < .001). The early recurrence was seen in 3 patients in the no tube group, while no early recurrence was determined during tube placement in the rectal and sigmoidal tube groups (15.0%, 0.0%, and 0.0%, respectively, P < .05, P < .05, and P > .05). The tubes were removed or spontaneously discharged in 13 (65.0%) and 12 patients (60.0%) in the rectal and sigmoidal tube groups, respectively, and sigmoid volvulus recurred in 2 patients in each group following the removal or spontaneous discharge. There was no statistically significant difference between the early recurrence rates of the no tube, rectal tube, and sigmoidal tube groups following the removal or spontaneous discharge of the tubes (15.0%, 15.4%, 16.7%, respectively, P > .05) and in total (15.0%, 10.0%, and 10.0%, respectively, P > .05). CONCLUSION: Flatus tubes may prevent the early volvulus recurrence during their placement in sigmoid volvulus. Nevertheless, they generally cause pain and discomfort, and they are frequently removed or spontaneously discharged, which suppresses their recurrence- preventive effects.

Management of sigmoid volvulus during labor : a challenging situation.

Acute intestinal obstruction is rare during pregnancy. Its diagnosis is difficult because the symptoms can be minimal and mimic signs of a regular pregnancy. Sigmoid volvulus is a common cause of these obstructions. The management is challenging because it depends on many factors, and affects maternal-fetal outcomes. We report a case of a 32-year-old woman with sigmoid volvulus associated with fetal demise that came during labor and we discuss the management options.

Factors precipitating volvulus formation in sigmoid volvulus.

BACKGROUND: Sigmoid volvulus (SV), the wrapping of the sigmoid colon around itself, is a rare intestinal obstruction form world-wide. For this reason, the physiopathology of SV, particularly the precipitating factors, are not clearly identified. The aim of this study is to evaluate the precipitating factors in SV. METHODS: The clinical records of consecutive 416 patients with SV were reviewed prospectively from January 1986 to July 2020. As a control, the records of consecutive 100 patients with non-volvulus intestinal obstruction were reviewed prospectively in the past 24 months. The premorbid symptoms including acute diarrhea, sudden and excessive body motions, overeating after a prolonged starvation, coughing spell, and labor was evaluated. RESULTS: Among the premorbid symptoms, 1-5-day interval of diarrhea (42 patients, 10.1%, p<0.05), harvesting activation (35 patients, 8.4%, p<0.05), and overeating after Ramadan fasting (31 patients, 7.5%, p<0.05) were found to be statistically significant precipitating factors in SV. CONCLUSION: Although there are few studies about the precipitating factors of SV in the literature, increased bowel motility, excessive body motions, and overeating following a prolonged starvation look like the precipitating factors in the development of SV.

The role of sigmoid colon anatomic dimensions in the development of sigmoid volvulus, North-Western Ethiopia.

INTRODUCTION: Sigmoid colon anatomic dimensions have been studied to have roles in the occurrence of sigmoid volvulus; however, these studies are few in number and failed to control the confounding effect of acute sigmoid obstruction on the anatomic dimensions. The main objective of this study was to assess the role of sigmoid colon anatomic dimensions in the development of sigmoid volvulus controlling the effect of acute sigmoid obstruction on the anatomic dimensions. MATERIALS AND METHODS: The study was carried out from Dec, 2019 to April, 2021 at Tibebe Ghion Specialized Hospital and Felege Hiwot Comprehensive Specialized Hospital, two referral hospitals in Bahir Dar city, North-Western Ethiopia to compare sigmoid anatomic dimensions among three independent groups of participants: patients with no history of sigmoid volvulus (I), those for whom elective surgery was done after non-surgical detorsion of sigmoid volvulus (II), and patients for whom emergency surgery was done for sigmoid volvulus (III). The anatomic dimensions were compared using fixed effects one-way ANOVA or Kruskal-Wallis H test at p-value ≤ .05 (two-sided) and Tukey method or Dunn-Bonferroni's test was used for post-hoc comparisons. RESULTS: A total of 66 consecutive eligible patients (22 for each of the three groups) were included and analyzed in the study. The means of anatomic dimensions (in cm) for groups (I, II, III) were: sigmoid colon length-SCL (35.91, 71.07, 80.86), meso-sigmoid height-MSH (17.11, 26.52, 28.86), meso-sigmoid maximal width-MSMW (9.70, 14.89,16.80), and meso-sigmoid root width-MSRW (8.34, 7.48, 8.11). SCL, MSH, MSMW, MSH/MSRW, and MSMW/MSRW were found to be statistically significantly different in patients with sigmoid volvulus. MSRW and MSH/MSMW were not different between the study groups. CONCLUSION: A long sigmoid colon with long and wide mesentery, but with a constant base is highly likely to predispose individuals to sigmoid volvulus.

Benign Colonic Strictures.

CASE SUMMARY: A 46-year-old man with no significant medical or surgical history presented to the emergency department with a 1-week history of worsening constipation, abdominal distension, nausea, and nonbloody, nonbilious emesis. Workup included a CT scan that was notable for a 5.3 × 3.9 cm "apple core-type" mass located within the sigmoid colon with proximal large-bowel dilation. Carcinoembryonic antigen was 1.4. No metastatic disease was seen on chest, abdominal, or pelvic CT scans. Flexible sigmoidoscopy identified a sigmoid colon mass 30 cm from the anal verge with near complete obstruction. Biopsies of the mass did not show evidence of dysplasia or malignancy. The Gastroenterology service declined to place a stent without a malignancy diagnosis. The patient subsequently underwent exploratory laparotomy, sigmoid colectomy, and end colostomy. Recovery was uneventful. Final pathology showed diverticulitis with abscess formation and no evidence of malignancy. A completion colonoscopy was unremarkable, and the patient underwent colostomy reversal 3 months later.

An infarcted wandering spleen leading to a sigmoid volvulus presenting with acute large bowel obstruction: a case report.

A wandering spleen is a very rare event characterised by the absence of the spleen in its anatomical position due to the hyperlaxity of its ligaments. We present a case of wandering spleen complicated by splenic vascular pedicle torsion, thrombosis and subsequent splenic infarction. Compression of the infarcted spleen on the rectosigmoid junction led to the development of a sigmoid volvulus, which presented as an acute large bowel obstruction. The patient underwent emergency laparotomy, splenectomy, sigmoid decompression and sigmoidopexy. After a follow-up period of two years, the volvulus had not recurred.

Recurrent sigmoid volvulus: Cause of colon perforation, sepsis, and fetal death.

Sigmoid volvulus is one of the most common reasons for intestinal obstruction. Recurrent sigmoid volvulus occurred in only a few cases. Torsion of the sigmoid colon around the mesenteric portion initiates ischemia, gangrene, and perforation. Here, we presented a case with recurrent sigmoid volvulus. A 19-year-old Syrian refugee has been admitted to emergency room during 30th gestation week with acute abdomen, constipation, and lack of gas passage. She had a medical history of rectosigmoidoscopy and detorsion of sigmoid volvulus 6 days ago. Her vital signs showed tachycardia, hypotension, and tachypne, and her body temperature was 35.6°C. Sonography revealed nonviable fetus. Emergency laparotomy has been performed. Sigmoid volvulus and contaminated intraperitoneal area with feces was evaluated. A cesarean section, total colectomy, and end-ileostomy have been performed. Patient stayed 3 days in intensive care unit and was discharged on the 17th day. Sigmoid volvulus is a real emergency. Delayed treatment of sigmoid volvulus is related to maternal and fetal mortality.

Hypogastric Artery-Colonic Fistula after Coil Embolization of Left Hypogastric Artery Aneurysm.

Coil migration into the colon is an extremely rare complication of aneurysm embolization and only three cases have been reported. Two of these cases were managed with resection of the involved colon and the remaining case was managed with serial imaging. We present a 70-year-old man who developed hematochezia 2 years after coil embolization of a ruptured left hypogastric artery aneurysm. The patient was successfully treated with diverting colostomy and endoscopic closure of the sigmoid colon defect. We present the only case report of the use of advanced endoscopy to treat endovascular coil migration.
