BACKGROUND

The Division of Colorectal Surgery at the Philippine General Hospital (PGH) conducts hundreds of surgeries annually for benign and malignant colorectal conditions. Since 2019, the Division has implemented an Enhanced Recovery After Surgery (ERAS) program to improve patient outcomes. However, its impact on hospital costs—critical for a government hospital—has not yet been studied.

This study aimed to evaluate the effect of ERAS on healthcare costs for elective colorectal surgeries performed at PGH in 2021.

A retrospective observational study was conducted on adult patients who underwent elective colorectal surgeries under the ERAS protocol in 2021. Medical and billing records were retrieved using the hospital’s electronic medical records (EMR) system, excluding cases with incomplete data. Procedures were categorized by type [stoma closure, colonic or rectal resection, reversal of Hartmann’s, or cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC)] and surgical approach (open, laparoscopic, or robotic). Costs were classified into diagnostics, facility fees, medications, surgery, and hospital supplies. ERAS compliance rates were extracted from the online ERAS Interactive Audit System (EIAS), and linear regression analysis was performed.

Among 114 elective colorectal surgeries, records for 90 cases were analyzed. Surgery-related expenses accounted for the highest mean hospital costs across all procedure types. An inverse correlation between ERAS compliance and total cost was observed for open surgeries, with statistically significant reductions in stoma closures and open colon resections (p-value: 0.0213 and 0.0134, respectively). However, minimally invasive surgeries (MIS) did not demonstrate cost reductions with increasing ERAS compliance, likely due to additional expenses associated with advanced equipment. Linear regression indicated that higher compliance rates generally led to decreased hospital costs.

Standardized care through ERAS has been associated with cost savings compared to traditional perioperative management. This study supports the conclusion that higher ERAS compliance can reduce hospital costs in open colorectal surgeries. However, the higher costs of MIS procedures, driven by equipmentrelated expenses, may offset potential savings from ERAS adherence. Further research is warranted to explore the cost implications of ERAS in MIS cases.

Background and Objective: One of the uses of indocyanine green (ICG) in the surgical field is the evaluation of the anastomotic margins in colorectal surgery. This is of particular importance because fluorescence imaging may aid in detecting vascular compromise, allowing the surgeon to change the resection margin thereby decreasing the chance of an anastomotic leak. To date, there has been no study with its use locally. This study aimed to determine whether the use of ICG can safely identify if the margins of resection are well-vascularized in patients undergoing left-sided colon or rectal surgery, which in turn may reduce anastomotic leak rates. Methods: Through a retrospective study design, the investigators gathered data of patients who underwent left-sided colon or rectal surgery. The groups were divided into those with and without the use of ICG and a comparative data on the anastomotic leak rates were analyzed. Results: Eighty-six (86) patients with similar patient characteristics, tumor staging, and surgical approach were compared. Both the leak rates identified during the initial hospital stay and at 30 days post-operatively were lower in those where ICG was used (p=0.035, p=0.047, respectively) than those where ICG was not used. Conclusion ICG fluorescence imaging may reduce the anastomotic leak rates in patients undergoing colorectal surgery.

BACKGROUND AND OBJECTIVE

Robotic surgery for rectal malignancies in the Philippines is emerging. Evidence has shown promising results for robot-assisted (R) rectal surgery when compared to the laparoscopic (L) and open (O) approach. This study discussed the clinicopathologic outcomes of the first robotic rectal resections versus laparoscopic and open rectal resections at the Philippine General Hospital (PGH).

This was a retrospective cohort of 45 consecutive surgical resections for rectal malignancy done at the PGH from March 2019 to October 2019 that compared the outcomes of the first 15 robotic procedures done at the institution versus laparoscopic (n=15) and open (n=15) operations performed during the same time period. One-way ANOVA was done to determine significant differences among variables, while Bonferonni multiple comparison test was done to analyze differences among means.

The 45 patients in the study had a mean age of 56.04 ± 13.45 years. The patients were mostly male (60%). Most of the tumors were located in the low rectum (27/45; 60%). Most of the patients had locally-advanced (at least Stage IIIB) disease (27/45; 60%), and warranted neoadjuvant treatment (41/45; 91.11%). Most patients underwent a sphincter-saving procedure (34/45; 75.56%). All three groups had comparable baseline characteristics. The R-group had the longest operative time (438.07 ± 124.57; p value < 0.0001). Blood loss was significantly highest in the R-group (399 ± 133.07 cc; p value - 0.0020) as well, while no statistical difference was observed between the Oand L-groups (p value – 0.75). No conversion to open was noted in the R- and L-groups. Most of the patients had well-differentiated adenocarcinoma (22/45; 48.49%). All patients in the L- and O-groups had an R0 resection There were two R1 resections in the R-group. All patients who underwent an open surgery had a negative circumferential resection margin (CRM); L-group 93.99%, R-group 69.23%. All patients had adequate proximal and distal resection margins. Those who underwent an open surgery had the shortest post-operative length of stay (LOS) (p value – 0.0002). Post-operative ileus (7/45; 15.56%) was the most commonly encountered morbidity, and was seen mostly in the R-group (3/15; 20%). One patient in the R-group underwent a transanal repair of an anastomotic dehiscence and was discharged three days after reoperation. There was no reported mortality.

Our institution with a beginning robotic colorectal surgery program showed promise as its initial outcomes for rectal cancer were compared to the more often-performed open and laparoscopic procedures. The authors expect more favorable clinicopathological outcomes as our staff overcome the prescribed learning curve for robotic surgery.

The duodenum is the most common extra-colonic site of diverticulum. If present, it rarely manifests with symptoms or complications. A case is discussed involving a 78-year-old female who presented with massive upper gastrointestinal bleeding from duodenal diverticula. Due to hemodynamic instability, she eventually underwent duodenal resection, with a side-to-side duodenojejunostomy as a means of restoring intestinal continuity. The postoperative course was unremarkable. The patient was able to feed enterally and had no recurrence of bleeding.

OBJECTIVE: Surgical site infection (SSI) is one of the most common healthcare-associated infections. This study aimed to determine SSI rate and the associated factors among colorectal surgery patients. METHODS: This included adult patients who underwent surgery under the Division of Colorectal Surgery from January to May 2018. Clinico-demographic, operative, and SSI outcome data were reviewed. Occurrence of SSI during admission until discharge, and up to 30 days after the surgery was analyzed. RESULTS: A total of 172 surgeries were performed. Majority were elective procedures (68.0%), and performed via open approach (67.4%). Most were malignant cases (62.6%). Sixty-three colorectal resections were done (41 colon and 22 rectal). SSI rate prior to discharge was 6.4%, and 15.7% at 30 days. Among colorectal resections, 18 (28.6%) patients had SSI at 30 days. SSI rates were significantly higher among patients who were ASA 2 or 3; received chemotherapy 12 weeks prior to surgery; had malignant pathology; underwent emergency surgery; received perioperative transfusion; had stapled skin closure; had low anterior resection for rectal cancer; and had multivisceral resection. CONCLUSION The Division of Colorectal Surgery at the Philippine General Hospital had a higher SSI rate as compared to literature. Although this could be partly explained by the differences in patient and surgeon population, improving on SSI rates will be the unit's goal. Continued SSI surveillance with more patient accrual may provide better insight to the associated risk factors.

Ninety percent of cases of malrotation have shown signs and symptoms of intestinal obstruction by the first year of life. It is thus an often-overlooked etiology in adult patients. Evidence-based recommendations are also limited because of the paucity of cases. This paper discusses the two cases of malrotation from diagnosis to surgical management at a tertiary academic hospital. Both are previously well adult male patients with virgin abdomen who presented with vomiting and signs of intestinal obstruction. During medical decompression, CT scan with triple contrast clinched the diagnosis of malrotation for which Ladd's procedure was done, with no operative complications. The authors' experience and previous literature support early decompression, imaging, and surgery for all cases of malrotation regardless of severity of symptoms.

Purpose: This study aims to evaluate surgical outcomes (i.e. length of stay [LOS], 30-day morbidity, mortality, reoperation, and readmission rates) with the use of the Enhanced Recovery After Surgery (ERAS) pathway, and determine its association with the rate of compliance to the different ERAS components. Methods: This was a prospective cohort of patients, who underwent the following elective procedures: stoma reversal (SR), colon resection (CR), and rectal resection (RR). The primary endpoint was to determine the association of compliance to an ERAS pathway and surgical outcomes. These were then retrospectively compared to outcomes prior to the implementation of ERAS. Results: A total of 267 patients were included in the study. The overall compliance to the ERAS component was 92.0% (SR, 91.8%; CR, 93.1%; RR, 90.7%). There was an associated decrease in morbidity rates across all types of surgery, as compliance to ERAS increased. The average total LOS decreased in all groups but was only found to have statistical significance in SR (12.1±6.7 days vs. 10.0±5.4 days, P=0.002) and RR (19.9±11.4 days vs. 16.9±10.5 days, P=0.04) groups. Decreased postoperative LOS was noted in all groups. Morbidity rates were significantly higher after ERAS implementation, but reoperation and mortality rates were found to be similar. Conclusion Increased compliance to ERAS protocol is associated with a decrease in morbidity across all surgery types. The implementation of an ERAS protocol significantly decreased mean hospital LOS, without any increase in major surgical complications. Having your own hospital ERAS pathway improves documentation and accuracy of reporting surgical complications.

Buschke-Lowenstein tumor (BLT) is a sexually transmitted infection (STI) caused by the human papillomavirus. This study investigated the profile, management, and outcomes of patients who underwent surgery for BLT from 2015 to 2019 at the Philippine General Hospital. Seven patients underwent surgery for BLT. All were male, with ages ranging from 21 to 41 years. Presenting symptoms were anal mass, foul-smelling discharge, pain, bleeding, and pruritus. All were positive for human immunodeficiency virus. All admitted to having engaged in both insertive and receptive anal intercourse, with multiple partners. All underwent excision with healing by secondary intention. Two had recurrence of warts. Four had an anal stricture. Of these, 3 underwent anal dilatation, while 1 had to undergo proximal bowel diversion. One had intraepithelial carcinoma without dermal invasion on histopathologic analysis. BLT is a rare STI characterized by local aggressiveness but with low malignant potential. Wide excision remains to be the mainstay of treatment.

Benign mesenchymal tumors of the urinary bladder are extremely rare. This is a case of a 56- year old female presenting with an enlarging abdomen initially managed as a case of an ovarian new growth. Aside from the ruptured ovarian mass, a urinary bladder mass was also noted intraoperatively and a surgical dilemma was resolved by imaging review. The patient underwent exploratory laparotomy, enterolysis, total hysterectomy, bilateral salpingooophorectomy, and partial cystectomy. Final histopathology identified the bladder tumor to be a leiomyoma. The patient had an uneventful postoperative course. Awareness of this clinical entity and presentation will aid in diagnosis and management.

This is a case of a 65-year-old female diagnosed with appendiceal carcinoma, who underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy. Profuse bleeding through the peritoneal drains, with hemodynamic instability, warranted a re-exploration on the fourth postoperative day. Intraoperatively, there was 500 mL of blood clots mostly on the right upper quadrant, diffuse muscle oozing along the previously-stripped right hemidiaphragm and right paracolic gutter, and a non-expanding hematoma on the right anterior abdominal wall. Bleeding parameters were checked postoperatively, and derangements pointing to a disseminated intravascular coagulation were noted. The patient was managed with multiple blood transfusions of packed red blood cells, fresh frozen plasma, platelet concentrates, and cryoprecipitate. Dexamethasone and tranexamic acid were given intravenously. The patient was discharged well on postoperative day 14 after clinical resolution of the bleeding. Eight days after discharge, however, patient succumbed to myocardial infarction.
