Fecal Scrotal Abscess Secondary to Spontaneous Retroperitoneal Perforation of Ascending Colon

Introduction. Fecal abscess or enterocutaneous fistulas of the scrotum are rare and are invariably the result of incarcerated bowel loop in inguinal hernia. Spontaneous perforation of the colon (SPC) having no definite cause is also rare. Much rarer is posterior colonic perforations causing an extensively large retroperitoneal abscess. Similarly, spread of retroperitoneal abscess to the thigh or scrotum has rarely been reported. We report a case of spontaneous posterior perforation of ascending colon resulting in large retroperitoneal abscess eventually causing scrotal abscess, which resolved on conservative treatment and drainage of the scrotal fecal abscess. Case Presentation. A 20-year-old male presented with gradually increasing noncolicky pain right side abdomen with nonprojectile vomiting, obstipation, and progressive abdominal distension. Clinically, the abdomen was tender with guarding over the right side with signs of inflammation on the right side back with no associated hernia. On conservative treatment, he was gradually improved but developed right side scrotal abscess a week later. CT abdomen showed a large retroperitoneal collection having multiple internal air lucencies, displacing ascending colon and caecum medically with discontinuity in the posterior wall of ascending colon. The large retroperitoneal collection was extending from right pararenal and posterior perihepatic soft tissue planes to the right iliac fossa and thigh. On drainage of the scrotal abscess, about 350 ml of fecal contents was evacuated. The patient gradually recovered and was discharged on conservative treatment with an uneventful 4-year follow-up. Conclusion. Diagnosis of retroperitoneal perforation of the colon is often delayed due to the absence of peritoneal irritation. An extensively large retroperitoneal abscess may spread the infection to the scrotum and thigh due to extreme pressure, possibly by dissecting away the transversalis fascia through a deep ring along the side of the spermatic cord. Timely performed CT/MRI can avoid delay in the diagnosis of retroperitoneal abscess and further spread of infection.

Massive subcutaneous emphysema in the upper leg

Subcutaneous emphysema of the extremities can be associated with necrotizing fasciitis, a surgical emergency. It can sometimes also be caused by local spreading of air from a retroperitoneal bowel perforation. Other than this specific symptom, the diagnosis of retroperitoneal perforation is usually impeded by lack of signs of peritoneal irritation.

Endoscopic Extraction of CBD Stone: single centre experience in tertiary care centre

Background and Aims: Introduction: Endoscopic Retrograde Cholangiopancreatography(ERCP) has become the first line treatment for patients with common bile duct (CBD) stones. This technique may fail, however, due to presence of a large stone, multiple stones, periampullary diverticula or CBD stricture. The aim of this study was to evaluate the success of CBD cannulation, Endoscopic Sphincterotomy(EST) and CBD clearance in initial attempt, identify the failures of stone extraction and assess the post-ERCP complications. Methods: A prospective study was carried out over the period of January 2019 to January 2020 on 100 consecutive patients with CBD stones. ERCP was done and the stone size and number recorded. EST was performed using a diathermy unit with a cutting current and stones were extracted using a Balloon catheter or a Dormia basket. Results: Of the 100 patients, 44 were male and 56 were female with mean age of 52}17years. Selective CBD cannulation and cholangiogram was achieved in 90%, EST was successful in 90% and complete stone clearance was achieved in first attempt in 46 patients (59%). 52 patients had difficult CBD stone. There were nine complications, most of which rapidly resolved on conservative treatment (four post-ERCP pancreatitis, three bleeding and one retroperitoneal perforation) and one mortality in an old lady due to PSVT that couldn’t be directly attributed to ERCP. Among patients with Stone less than 15 mm in diameter(n=58), stone was removed successfully in 45 patients(78%) whereas in patients with stones over 15 mm (n=20) only one was removed successfully (5%) at initial attempt. Of these 32 patients with residual stones, 13 were referred for surgery and 19 had insertion of biliary stent to be followed by repeat ERCP. Conclusion: Endoscopic therapy is a simple, effective and safe method of treatment in patients with CBD stone.

Retroperitoneal perforation of a duodenal diverticulum containing a large enterolith after Roux-en-Y bypass and cholecystectomy

Roux-en-Y gastric bypass (RYGB) is one of the most frequently performed bariatric procedures worldwide. The postoperative incidence of cholelithiasis after RYGB is higher than in the general population (30% vs. 2–5%), because the altered anatomy may lead to impaired gallbladder motility and biliary stasis. We report the case of a 47-year-old female who presented 9 years after RYGB and cholecystectomy with acute pain in the upper abdomen because of a retroperitoneal perforation of a duodenal diverticulum. Intraoperatively, a huge enterolith was found in the diverticulum and removed via duodenotomy. We claim that the stone grew during the sober states as the bile accumulated locally, because the gall bladder has already been removed and no duodenal food passage remained. This acute and life-threatening situation was successfully managed by operation. Consequently, a duodenal diverticulum has to be considered as a possible but very rare complication after RYGB and cholecystectomy.
